Small study (n = 12), showing that immune responses to SARS-CoV-2 mRNA vaccines are induced in most patients who have been treated with CAR-T cell therapies targeting B cell lineage antigens.


Collier AR, Yu J, Mcmahan K, et al. COVID-19 mRNA Vaccine Immunogenicity in Immunosuppressed Individuals. J Inf Dis November 18 2021, jiab569, https://academic.oup.com/jid/advance-article/doi/10.1093/infdis/jiab569/6430790

This study analyzed 69 participants who were receiving immunosuppressive therapy (IS) for solid organ transplant, bone marrow transplant, and/or chronic inflammatory disease. IS reduced neutralizing, binding, and non-neutralizing antibody functions in addition to CD4 and CD8 T cell IFN-γ responses following mRNA vaccination compared to immunocompetent individuals. Moreover, IS therapy reduced cross-reactivity against SARS-CoV-2 variants. According to the authors, these populations will “likely not be protected by the current two dose regimens of mRNA COVID-19 vaccines”.

See title. In this small study from Switzerland, response rates of S-specific CD8+ T cells were higher in 26 ocrelizumab-treated (96%) and 11 rituximab-treated patients (82%) as compared to 22 controls (67%). S-specific T cells were polyfunctional but expressed more activation markers in patients than in controls. The authors conclude that this elicited T cell memory response “could reduce complications of SARS-CoV-2 infection in this vulnerable population”.

In 77 patients with chronic inflammatory diseases treated with immunosuppressive drugs, longitudinal analysis showed the greatest reductions in neutralizing antibodies and Fc effector functions capacity in individuals treated with TNF-α inhibitors (TNFi), and this pattern appeared worse against Delta. Within five months of vaccination, serum neutralizing titers of all TNFi-treated patients tested fell below the presumed threshold correlate for protection. However, TNFi-treated patients receiving a third mRNA vaccine dose boosted their neutralizing antibody titers by more than 16-fold.

Anti-COVID-19 immunity dynamics were assessed in patients with cancer in a small cohort. Waning of immunity was detected 4-6 months post-vaccination with significant increases in anti-spike IgG titers after booster dosing, and 56% (18/32) of seronegative patients seroconverted post-booster vaccination. Prior anti-CD20/BTK inhibitor therapy was associated with reduced vaccine efficacy.

Good news for all who are treated with immunosuppressive drugs. In this propensity score matched cohort (including 12,841 immunosuppressed patients and 29,386 non-immunosuppressed patients), immunosuppression was associated with a reduced risk of invasive ventilation (HR 0.89, 95% CI: 0.83–0.96). With the exception of rituximab (HR 1.72, 1.10–2.69), there was no increased risk of mechanical ventilation or in-hospital death for the rheumatological, antineoplastic, or antimetabolite therapies examined.

Lancet Oncology November 09, 2021. https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045(21)00574-X/fulltext

The VOICE trial was the first prospective COVID-19 vaccination trial in patients with solid tumours: the vast majority developed an adequate antibody response to vaccination with mRNA-1273 (MODERNA). However, 9 (7%) of 131 of the patients treated with immunotherapy, 37 (16%) of 229 of the patients treated with chemotherapy, and 16 (11%) of 143 of the patients treated with chemoimmunotherapy were classified as suboptimal responders or non-responders compared with one (<1%) of 240 of the participants without cancer.

With regard to COVID-19 severity, patients with cancer represent a heterogenous group. In this large cohort of patients with COVID-19, those with recent cancer treatment had significantly higher rates of adverse outcomes compared with patients without cancer. In the fully adjusted models, however, only patients with recent cancer treatment had a statistically significant increase in the 30-day risk of death, ICU stay, and hospitalization. Patients with no recent cancer treatment had similar or even lower risks.

Routine immunization services faced stark challenges in 2020, with the COVID-19 pandemic causing the most widespread and largest global disruption in recent history. Although the latest coverage trajectories point towards recovery in some regions, a combination of lagging catch-up immunization services, continued SARS-CoV-2 transmission, and persistent gaps in vaccine coverage before the pandemic still left millions of children under-vaccinated or unvaccinated against preventable diseases at the end of 2020, and these gaps are likely to extend throughout 2021.

JAMA Netw Open June 28, 2021; 4(6):e2114866. https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2781462?resultClick=1

This cross-sectional study suggests that the COVID-19 pandemic was associated with impaired mental health. The mental well-being and life satisfaction in adolescents in Austria were significantly lower in 2021 compared with 2018. However, owing to the online nature of the study, a self-selection bias toward higher participation of adolescents with a higher mental health burden may be possible.

One day, when humans will all be gone from earth, nature will quickly come out of its holes. Mountain lions first (according to this study where GPS collars were placed on six animals). Results: The drastic change in human behavior due to the Covid-19 pandemic had cascading effects on mountain lion habitat selection. Under normal circumstances, mountain lions strongly avoid urban areas. When human mobility declined by more than 50% during the Covid-19 associated lockdown, mountain lions relaxed their fear of the urban edge during the lockdown.

A decrease in influenza was already seen following relatively modest control measures, including mask-wearing recommendations among only ill or symptomatic individuals. Influenza remained nearly absent for the remainder of 2020. International travel restrictions likely contributed to this. For enterovirus/rhinovirus and adenovirus, reductions were only seen after lockdown, and these viruses rebounded earlier than others. Continued mandatory mask wearing did not appear to prevent this.

Crime largely decreased around the globe during COVID-19 stay-at-home orders, but with substantial variation across cities and types of crime. Property-based crimes decreased substantially, but homicide was relatively unchanged. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime.

This large study shows a weak immunogenicity of mRNA vaccines in transplant recipients. In 367 patients the prevalence of anti–SARS-CoV-2 antibodies was 33.8% one month after the second dose. Recipients of liver transplant showed a better humoral response than recipients of other organs. According to the authors, an increased antigen dose or a third vaccine dose can be proposed to improve the vaccination response in this specific population. Of note, the French Health Authorities have recently recommended offering a third dose to immunosuppressed patients.

In this cohort study of 102 patients with cancer from Israel who were receiving active treatment and 78 healthy controls, 92 patients with cancer (90%) and 100% of the controls were seropositive after the BNT162b2 vaccine (BioNTech/Pfizer). The median IgG titer in the patients with cancer was significantly lower than that in the controls. In a multivariate analysis, the only variable that was significantly associated with lower IgG titers was treatment with chemotherapy plus immunotherapy.

PLoS ONE 16(4): e0250796. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250796

In this prospective observational cohort study of 210 consecutive solid organ transplant recipients hospitalized with COVID-19 in 12 Spanish centers, four baseline features were identified as independent predictors of intensive care need or death: advanced age, high respiratory rate, lymphopenia, and elevated level of lactate dehydrogenase. A shorter interval between transplantation and COVID-19 diagnosis had a negative impact on clinical prognosis.

This study showed significant differences in ACE2 and protease expression in normal and malignant tissues with a subgroup expressing very high levels of ACE2 RNA (in particular in NSCLC and gastrointestinal cancer). These findings, together with the increased presence of inflammatory cells in tumors displaying high ACE2 levels might explain why cancer patients are more severely affected by COVID-19.

Some evidence indicates immunosuppressive therapy inhibits humoral response to the influenza, pneumococcal and hepatitis B vaccines. The degree to which this will translate to impaired COVID-19 vaccine responses is unclear. This article outlines the existing data on the effect of anti-rheumatic therapy on vaccine responses in patients with inflammatory arthritis and formulates a possible pragmatic management strategy for COVID-19 vaccination.

Analyzing 75,463 patients from the UK, Chloe Bloom and colleagues show that patients with chronic pulmonary disease had a high level of mortality, with a prevalence of 40% for in-hospital death. Of patients with asthma, only those with severe asthma had increased mortality compared to those without an underlying respiratory condition. Patients with asthma (aged ≥ 50 years) had a lower mortality risk if they had used inhaled corticosteroids within 2 weeks of admission.

A large single-center, retrospective analysis of 820 cancer patients with COVID-19 treated with various immunomodulatory agents within 90 days prior to SARS-CoV-2 diagnosis, mainly anti-CD20 therapies (rituximab, ofatumumab, or obinutuzumab) and immunotherapy (PD-1, PDL-1, or CTLA-4 blockade). Of note, whereas cytotoxic chemotherapy itself was not a risk for worse outcomes, pre-COVID-19 neutropenia was associated with worse COVID-19. In assessing whether certain oncologic medications are associated with worse COVID-19 outcomes, considering cancer type, degree of effect (i.e. neutropenia or other bone marrow suppression) and other patient-specific factors is crucial.

What is the potential biological rationale behind the enhanced risk of COVID-19 among cancer patients? Jennifer Yin Yee Kwan from Toronto and colleagues suggest an increased expression of SARS-CoV-2 viral entry genes in the cancer state, particularly in respiratory, gastrointestinal, and genitourinary tract tissues. Elevation of ACE2, TMPRSS2, and CTSL in cancer vs. normal tissue was observed in many of the tissues examined. Moreover, it appeared that some entry genes have transient elevation with radiotherapy or chemotherapies.

This large case-control study from Denmark indicates that patients treated for hypothyroidism or hyperthyroidism do not have an increased risk of contracting SARS-CoV-2 infection. The results also suggest that treatment for thyroid dysfunction, when controlling for relevant confounding, does not influence the prognosis of SARS-CoV-2 infection.

This deterministic, compartmental HIV transmission model for MSM in Baltimore, US, used available data on COVID-19-related disruptions to HIV services to predict effects of reductions in sexual partners, condom use, HIV testing, viral suppression, PrEP and ART use. Results: it depends. A 25% reduction in sexual partnerships is estimated to offset the effect of the combined service disruptions on new HIV infections.

Patients without disease modifying therapies (DMTs), with previous cardiovascular diseases, or with a severe degree of disability may be at a higher risk of severe COVID-19. In this review of 873 published cases, immunosuppressive therapy itself did not appear to be a substantial risk factor. The authors argue that it might be reasonable to assume that these therapies could be protective, either directly by mitigating the cytokine storm, or indirectly by reducing the disease activity of MS.

  • Mortality increased in stepwise fashion according to Child-Pugh class.
  • Other risk factors for death included advancing age and alcohol-related liver disease.
  • Mortality risk was higher in patients with advanced cirrhosis than propensity-score-matched controls without liver disease.
  • The majority of deaths in patients with cirrhosis were from COVID-19-related lung disease.

In people living with HIV (PLWH), immune deficiency is a possible risk factor for severe COVID‐19, even in the setting of HIV virologic suppression. There is no evidence for a protective effect of PIs or tenofovir alafenamide. This is the result of a multi-center cohort study which evaluated risk factors for morbidity and mortality of COVID‐19 in PLWH infected with SARS‐CoV‐2 in three countries. Patients with severe COVID‐19 had a lower current CD4 T cell count and a lower CD4 T cell nadir, compared with patients with mild‐to‐moderate COVID‐19. In a multivariate analysis, the only factor associated with risk for severe COVID‐19 was a current CD4+ T cell count of < 350/µl (adjusted odds ratio 2.85, 95% confidence interval 1.26‐6.44, p = 0.01). The only factor associated with mortality was a low CD4 T cell nadir.

What do you know about the relationships between substance use disorders (SUDs), overdose and COVID-19 severity and mortality? Patients with histories of SUD and drug overdose could face disproportionate risk of critical COVID-19 illness, is the answer by Bennett Allen et al. However, the authors concede that they cannot assure whether the outcomes were due to COVID-19 or unrelated because they adjusted for few comorbidities. In particular, due to missing data, body mass index was not assessed.

Of the total Scottish population on March 1, 2020 (n = 5.463.300), the population with diabetes was 319.349 (5,8%), 1082 (0,3%) of whom developed fatal or critical care unit treated COVID-19 by July 31, 2020. In the population without diabetes, 4081 (0,1%) of 5.143.951 people developed fatal or critical care unit-treated COVID-19. As of July 31, the overall odds ratio (OR) for diabetes, adjusted for age and sex, was 1,395 compared with the risk in those without diabetes. The OR was 2,4 in type 1 diabetes and 1,4 in type 2 diabetes. Among people with diabetes, adjusted for age, sex, and diabetes duration and type, those who developed fatal or critical care unit-treated COVID-19 were more likely to be male, live in residential care or a more deprived area, have a COVID-19 risk condition, retinopathy, reduced renal function, or worse glycemic control, have had a diabetic ketoacidosis or hypoglycemia hospitalization in the past 5 years, be on more anti-diabetic and other medication (all p < 0.0001), and have been a smoker (p = 0.0011).

Among 66.646 (6,5%) admissions with a COVID-19 diagnosis across 613 US hospitals, 12.388 (18,6%) died in-hospital. In multivariable analysis, male sex was independently associated with 30% higher mortality risk (aRR, 1.30, 95% CI: 1.26 – 1.34). Of note, diabetes without chronic complications was not a risk factor at any age (aRR 1.01, 95% CI: 0.96 – 1.06), and hypertension without chronic complications was only a risk factor in younger people (20-39 year-olds) (aRR, 1.68, 95% CI: 1.17 – 2.40). Diabetes with chronic complications, hypertension with chronic complications, and obesity were risk factors in most age groups, with highest relative risks among 20-39 year-olds (respective aRRs 1.79, 2.33, 1.92; p ≤ 0.002).

According to this brief review, many questions about COVID-19 in patients with rheumatic diseases remain unanswered. These patients, when analyzed as a combined group, might have a slightly increased risk of death, although the role of disease activity and treatment was not taken into account in most studies. Chronic use of glucocorticoids at moderate or high doses is associated with hospitalization for severe COVID-19. Treatment with cytokine inhibitors could reduce the risk of SARS-CoV-2 infection, although the mechanisms of this protective effect are not clear.

The OpenSAFELY project analysed factors associated with COVID-19 deaths in 17 million patients. The picture that arose differs significantly from initial reports. For example, hypertension is not an independent risk factor for COVID-19 death, but renal disease very much is. Dialysis (aHR 3.69), organ transplantation (aHR 3.53) and CKD (aHR 2.52 for patients with eGFR < 30 mL/min/1.73 m2) represent three of the four co-morbidities associated with the highest mortality risk from COVID-19. The risk associated with CKD Stages 4 and 5 is higher than the risk associated with diabetes mellitus (aHR range 1.31–1.95, depending upon glycemic control) or chronic heart disease (aHR 1.17). This article defines essential action points, among which is advocating the inclusion of CKD patients in clinical trials, testing the efficacy of drugs and vaccines to prevent severe COVID-19.

In this multicenter cohort study following more than 1,3 million patients with hypertension from the USA and Spain, no clear association of increased risk of COVID-19 diagnosis, hospital admission, or subsequent complications was seen with the outpatient use of ACEI or ARB. These findings support recent recommendations that patients should not halt their ACEI or ARB therapy despite previously posited mechanisms of increased COVID-19 risk. Furthermore, the marginal difference between ACEIs and ARBs does not warrant class switching to reduce COVID-19 susceptibility.

Tofacitinib is a Janus kinase inhibitor (JAKi) approved for the treatment of ulcerative colitis (UC) and other immune-mediated diseases. As many JAKis, it is also evaluated in COVID-19 trials. Manasi Agrawal and colleagues here describe characteristics and outcomes of COVID-19 in 37 patients with IBD treated with tofacitinib compared with other medications in the SECURE-IBD registry. Overall, they found no difference in COVID-19 outcomes between the two groups. Good to see: though tofacitinib at the higher dose has been associated with venous thromboembolism, none of the tofacitinib-treated patients in this cohort experienced thrombotic complications.

Some reports of Guillain-Barré syndrome (GBS) have emerged during the coronavirus disease 2019 (COVID-19) pandemic. Here, Michael Lunn, Stephen Keddie and colleagues from University College London Hospitals NHS Foundation Trust studied the epidemiology of GBS cases reported to the UK National Immunoglobulin Database from 2016 to 2019 and compared it to cases reported during the COVID-19 pandemic. The result: GBS incidence has fallen during the pandemic, which may be the influence of lockdown measures reducing transmission of GBS inducing pathogens such as Campylobacter jejuni and respiratory viruses.

Asthma may not be a risk factor for poor prognosis of COVID-19. In a nationwide retrospective cohort study, Seon Cheol Park, Sang Chul Lee and colleagues from South Korea selected 7272 adult COVID-19 patients, 686 of whom had a history of asthma. After adjusting for age, sex, and the Charlson comorbidity score, asthma was not a significant risk factor for respiratory failure or mortality among all COVID-19 patients (odds ratio [OR] = 0,99, p = 0,997 and OR = 1,06, p = 0,759). Only a history of acute exacerbation in the previous year before COVID-19 was a significant risk factors for death (OR = 2,63, P = 0,043).

Sporadic episodes of sexual dysfunction? Don’t worry, it’s COVID. The reassuring news has just been published by Mehmet Gökhan Çulha and colleagues in a short summary of an online survey among 185 healthcare professionals. Sexual desire, weekly sexual intercourse/masturbation number, foreplay time, sexual intercourse time – everything decreased. When factors affecting sexual dysfunction were analyzed as univariate and multivariate, sexual dysfunction was shown to be significantly more common in males and alcohol users.

HIV infection and COVID-19 death: a population-based cohort analysis of UK primary care data and linked national death registrations within the OpenSAFELY platform. Lancet HIV 2020, published 11 December. Full-text: https://doi.org/10.1016/S2352-3018(20)30305-2

Should people with HIV in the UK be at increased risk of COVID-19 mortality? This would be the suggestion of a retrospective cohort study by Ben Goldacre, Krishnan Bhaskaran and colleagues who analyzed the data of 17 282 905 adults, of whom 27 480 (0·16%) had HIV recorded. 14,882 COVID-19 deaths occurred during the study period, with 25 among people with HIV. People living with HIV had higher risk of COVID-19 death than those without HIV after adjusting for age and sex: hazard ratio (HR) 2·90 (95% CI 1·96–4·30; p<0·0001). In a comment, Laura Waters and Anton Pozniak urge for caution in interpretating the results of this study. (Waters LJ, Pozniak AL. COVID-19 death in people with HIV: interpret cautiously. Lancet HIV 2020, published 11 December. Full-text: https://doi.org/10.1016/S2352-3018(20)30332-5.) They emphasize a low absolute mortality of less than 0·1% and recall that 23 (92%) of 25 people with HIV who died had comorbidities.

Several studies suggest that mental health deteriorated in many countries before and during lockdowns. The authors show that the highest levels of depression and anxiety occurred in the early stages of lockdown but declined fairly rapidly, possibly because individuals adapted to circumstances.

PubMed: https://pubmed.gov/33268442. Full-text: https://doi.org/10.1136/annrheumdis-2020-218310

Large French database, including patients with inflammatory rheumatic and musculoskeletal diseases (iRMD). Of 694 adults, 438 (63%) developed mild (not hospitalized), 169 (24%) moderate (hospitalized non-ICU) and 87 (13%) severe (ICU/deceased) disease. In multivariable imputed analyses, the variables associated with severe infection were age, male gender, hypertension and higher BMI. Use of corticosteroids (OR=1.97), mycophenolate mofetil (OR=6.6) and rituximab (OR=4.21) were also risk factors.

Registry case data from Italy: the cumulative incidence of SARS-CoV-2 infection in solid organ transplantation recipients (SOTRs) is three times higher than that estimated for the Italian population, highlighting that SOTRs are more at risk of infection than non-SOTRs. The 30- and 60-day cumulative incidence of mortality of COVID+ SOTRs was twice as high when compared to non-SOTRs.

Peripheral nerve injury can occur in COVID-19 patients secondary to post-infectious inflammatory neuropathy, prone positioning-related stretch/compression injury, systemic neuropathy, or nerve entrapment from hematoma. MR neurography and high-resolution ultrasound are excellent diagnostic tools for peripheral nerve injury. For COVID-19 patients and survivors with neuromuscular complications, imaging of peripheral nerves can aid medical decision-making, rehabilitative care, and patient/family counseling.

Oops! In this retrospective study on 689 patients with COVID-19 and Type 2 diabetes from Wuhan, China, insulin treatment was associated with a significant increase in mortality (27.2% vs. 3.5%; adjusted HR, 5.38). Further analysis showed that insulin treatment was associated with enhanced systemic inflammation and aggravated injuries of vital organs. However, this was a retrospective observation which could not establish a causal effect relationship between insulin treatment and high mortality. Moreover, there were significant differences in several baseline characteristics and laboratory indices at admission (for examples, SpO2, NT-proBNP and albumin), which may contribute to the different severity and outcome observed in patients treated with insulin.

Gunjan L. Shah from Memorial Sloan Kettering Cancer Center and colleagues retrospectively investigated 77 patients with SARS-CoV-2 who were recipients of cellular therapy (Allo, 35; Auto, 37; CAR T, 5; median time from cellular therapy, 782 days). Overall survival at 30 days was 78%. Mortality was largely driven by patients with active malignancy, especially relapsed leukemia, in whom the goals of care were affected both by COVID-19 severity and the decision to forgo anti-cancer treatment during an active infection. Immune profiling revealed reductions and rapid recovery in lymphocyte populations across lymphocyte subsets. Many patients were able to recover from COVID-19 infection and mount an antibody response with similar overall survival to the general hospitalized population.

Vitamin D might have beneficial potential due to its immunomodulatory and anti-inflammatory properties. But is a deficiency associated with disease severity? Perhaps. In this cross-sectional study, 335 COVID-19 patients admitted to the Wuhan Tongji Hospital were retrospectively analyzed. A vitamin D deficiency (< 30 nmol/L) was significantly associated with COVID-19 severity (OR 2.7). Prospective studies have to confirm these results.

Patients with diabetes mellitus are at increased risk of severe COVID-19. The authors discuss potential pathogenetic links between COVID-19 and diabetes mellitus; tight control of glucose levels; explain that insulin and dipeptidyl peptidase 4 inhibitors can be used safely in patients with diabetes mellitus and COVID-19; and caution that metformin and sodium–glucose co-transporter 2 inhibitors might need to be withdrawn in patients at high risk of severe disease.

Survivors of COVID-19 appear to be at increased risk of psychiatric sequelae. Here, Maxime Taquet and colleagues used a global federated network that captures anonymized data from electronic health records in 54 health care organizations in the US, totaling 69.8 million patients and 62,354 patients diagnosed with COVID-19. In patients with no previous psychiatric history, a diagnosis of COVID-19 was associated with increased incidence of a first psychiatric diagnosis in the following 14 to 90 days compared with six other health events (i.e., hazard ratio [HR] 2.1 vs influenza). The HR was greatest for anxiety disorders, insomnia, and dementia. The incidence of a first diagnosis of dementia in the 14 to 90 days after COVID-19 diagnosis was 1.6% in people older than 65 years. A psychiatric diagnosis in the previous year was associated with a higher incidence of COVID-19 diagnosis (relative risk 1.65).

Among a total of 1685 patients who were hospitalized with COVID-19, 473 (28%) received psychiatric diagnoses prior to hospitalization. After controlling for demographic characteristics, other medical comorbidities, and hospital location, the risk of death remained significantly greater among patients with a psychiatric disorder (hazard ratio, 1.5; 95% CI, 1.1-1.9; P = .003). Reasons are unclear. Psychiatric symptoms may arise as a marker of systemic pathophysiologic processes such as inflammation, that may, in turn, predispose to mortality. Similarly, psychiatric disorders may augment systemic inflammation and compromise the function of the immune system, while psychotropic medications may also be associated with mortality risk. Or is there confounding?

More health workers seem to have died in Mexico than anywhere else. Why? Limited specialized equipment of poor quality. Working conditions, workplace safety, job continuity (contracts) have all also been cited. Mexico also keeps “a very disaggregated register of the numbers on health worker deaths.”

Among 286 HIV-infected patients who were included by US healthcare providers, mortality rates were 9.4% (27/286) overall, 16.5% (27/164) among those hospitalized, and 51.5% (24/47) among those admitted to an ICU. Older age, chronic lung disease, and hypertension were associated with severe outcomes. A lower CD4 count (< 200 cells/mm³) was associated with the primary and secondary endpoints. There was no association between the antiretroviral regimen or lack of viral suppression and predefined outcomes.

A systematic search was performed for articles published up to June 15, 2020, revealing 223 liver transplant recipients with COVID-19 in 15 studies. Immunosuppression was modified in 32.8% of recipients. The case fatality rate was 19.3%. Dyspnea on presentation, diabetes mellitus, and age 60 years or older were significantly associated with increased mortality (P ≤ 0.01) with a trend to a higher mortality rate observed in those with hypertension and those receiving corticosteroids at the time of COVID-19 diagnosis.

Is treatment for vitamin D deficiency associated with reductions in the risk of COVID-19? Maybe. In this retrospective cohort study of 489 patients who had a vitamin D level measured in the year before COVID-19 testing, the relative risk of testing positive for COVID-19 was 1.77 times greater for patients with likely deficient vitamin D status compared with patients with likely sufficient vitamin D status. However, as with all retrospective studies, be aware of confounding: vitamin D deficiency may be a consequence associated with a range of chronic health conditions or behavioral or environmental factors that increase COVID-19 risk.

Among 198 CLL patients diagnosed with symptomatic COVID-19 across 43 international centers, the overall case fatality rate was 33%, although 25% remain admitted. Watch-and-wait and treated subgroups had similar rates of admission, ICU admission, intubation and mortality. Of note, CLL-directed treatment with Bruton tyrosine kinase inhibitors (BTKis, have been proposed as a potential treatment for COVID-19) at COVID-19 diagnosis did not impact survival, though BTKis were held during the COVID-19 course for most patients.

In this retrospective multicenter study, which included 402 allo-HCT recipients (adults and children) with upper and/or lower respiratory tract disease (RTD) caused by seasonal HCoV diagnosed through multiplex PCR assays 2012-2019, a significant morbidity was found. HCoV infection frequently required hospitalization (18%), oxygen administration (13%) and ICU admission (3%). Three-month overall mortality after HCoV detection was 7% in the full cohort and 16% in those with lower RTD. Three conditions were identified with higher mortality in recipients with lower RTD: low absolute lymphocyte counts, corticosteroids and, not suprisingly, ICU admission.

No increased risk of death for patients with liver transplants. In this multicenter cohort study, Gwilym Webb et al. collected data on 151 adult liver transplant recipients from 18 countries and 627 patients who had not undergone liver transplantation. After adjusting for age, sex, creatinine concentration, obesity, hypertension, diabetes, and ethnicity, liver transplantation did not significantly increase the risk of death in patients with SARS-CoV-2 infection. However, ICU admission (43 [28%] vs 52 [8%], p<0·0001) and invasive ventilation (30 [20%] vs 32 [5%], p < 0·0001) were more frequent in the liver transplant cohort.

Do PPIs increase the odds for acquiring SARS-CoV-2 infection? Maybe. Using an online survey of 53,130 participants (3,386 with a positive test), Christopher V Almario and colleagues found that individuals using PPIs either once daily (aOR 2.15; 95% CI, 1.90-2.44) or twice daily (aOR 3.67; 95% CI, 2.93-4.60) had significantly increased odds for reporting a positive COVID-19 test when compared with those not taking PPIs. Individuals taking histamine-2 receptor antagonists were not at elevated risk. However, before you stop your PPI: please consider that like all observational studies, this study is very susceptible to confounding (for example, people suffering from other comorbidities may be more likely to take PPIs). Moreover, people participating in this survey were not representative of the general population. Let’s keep an eye out for more data.

Retrospective cohort study of 1,213 hospitalized individuals with COVID-19 and pre-existing type 2 diabetes (T2D). Metformin use was significantly associated with a higher incidence of acidosis, particularly in cases with severe COVID-19, but not with 28-day COVID-19-related mortality. Furthermore, metformin use was significantly associated with reduced heart failure and inflammation. These findings provide some evidence in support of continuing metformin treatment in individuals with COVID-19 and pre-existing T2D, but acidosis and kidney function should be carefully monitored.

SARS-CoV-2 infection may cause thrombotic vascular events. In patients presenting with large vessel stroke during the COVID-19 pandemic, COVID-19 patients were significantly younger, with a mean age of 59 years, than patients who tested negative for SARS-CoV-2, who had a mean age of 74 years. Johanna Fifi and J Mocco recommend that, in otherwise healthy, young patients who present with stroke during the pandemic, the diagnosis of COVID-19 should be thoroughly investigated.

Among a total of 309 patients with cancer and concurrent COVID-19 at the Memorial Sloan Kettering Cancer Center, cytotoxic chemotherapy administered within 35 days of a COVID-19 diagnosis was not significantly associated with a severe or critical COVID-19 event (HR, 1.10; 95% CI, 0.73 to 1.60). However, patients with active hematologic or lung malignancies, peri–COVID-19 lymphopenia, or baseline neutropenia had worse COVID-19 outcomes. Findings remained consistent in a multivariate model and in multiple sensitivity analyses.

Using data from Kaiser Permanente Northern California, a large health care delivery system with 255 clinics providing care for more than 4.4 million persons throughout Northern California, Mathew Solomon and colleagues show that the weekly rates of hospitalization for acute myocardial infarction decreased by up to 48% during the COVID-19 period. Decreases were similar among patients with NSTEMI (incidence rate ratio, 0.51) and those with STEMI (0.60). Of note, demographic characteristics, hemodynamic measures on admission, initial and peak troponin I values, and the burden of other examined co-existing conditions were similar in patients who presented during the COVID-19 period and in those who presented before the first case of COVID-19 occurred.

In some years and in some countries, the annual influenza epidemic can result in tens of thousands in deaths. Now clinicians face a second respiratory virus associated with morbidity and mortality several-fold higher than that of influenza. In this short Insight article, Daniel Solomon and colleagues stress the importance of widespread implementation of seasonal influenza vaccination and preservation of non-pharmacologic interventions (such as mandatory face coverings in public, closure of schools and retail spaces, and restrictions on movement) until community immunity is achieved through an effective SARS-CoV-2 vaccine and/or natural infection.

A double hit by Jonathan Valabhji and colleagues! In the first paper (Holman et al.), the authors did a population-based cohort study of people with diabetes in the UK. Between 16 February and 11 May 2020, 1,604 people with type 1 diabetes and 36,291 people with type 2 diabetes died from all causes. Of these deaths, 464 in people with type 1 diabetes and 10,525 in people with type 2 diabetes were defined as COVID-19 related, of which 289 (62.3%) and 5,833 (55.4%), respectively, occurred in people with a history of cardiovascular disease or with renal impairment (eGFR < 60 mL/min per 1.73 m2). Increased COVID-19-related mortality also corresponded with glycemic control and body mass index.

In the second paper (Barron et al.), the authors did a whole-population study assessing risks of in-hospital death with COVID-19 between 1 March and 11 May 2020. Among the 23,698 in-hospital COVID-19-related deaths, a third occurred in people with diabetes: 7,434 (31.4%) in people with type 2 diabetes, 364 (1.5%) in those with type 1 diabetes, and 69 (0.3%) in people with other types of diabetes.

In this retrospective cohort study, Sara Tartof and colleagues determined the adjusted effect of body mass index (BMI), associated comorbidities, sociodemographic factors, and other factors on risk for death due to COVID-19. Compared with patients with a BMI of 18.5 to 24 kg/m2, those with BMIs of 40 to 44 kg/m2 and greater than 45 kg/m2 had relative risks of 2.68 and 4.18, respectively. This risk was most striking among those aged 60 years or younger and men. The authors found no increased risk for death associated with Black or Latino race/ethnicity or other sociodemographic characteristics.

Myasthenia gravis is an autoimmune disease in which antibodies bind to acetylcholine receptors (AChRs) or to functionally related molecules in the post-synaptic membrane at the neuromuscular junction. Now Domenico Restivo and colleagues describe 3 patients without previous neurologic or autoimmune disorders who were diagnosed with myasthenia gravis within 5 to 7 days after fever onset related to COVID-19. The authors speculate that antibodies directed against SARS-CoV-2 proteins might cross-react with AChR subunits.

One-third of U.S. adults reported experiencing stress, anxiety, and great sadness that was difficult to cope with by themselves, a significantly higher proportion than in other countries. Over 30 percent of Americans faced negative economic impacts due to the pandemic, significantly more than in the comparison high-income countries. Can the US do more regarding mental health, an existing concern before COVID-19?

Is COVAN the new HIVAN? Collapsing glomerulopathy was first characterized in the setting of HIV infection and termed HIV-associated nephropathy (HIVAN). In recent months, five case reports of collapsing glomerulopathy akin to those seen during the HIV epidemic have been published describing cases of collapsing glomerulopathy in association with SARS-CoV-2 infection. All of these cases were in patients of African ethnicity. Juan Carlos Velez and co-authors propose the term COVID-19-associated nephropathy (COVAN) to be used to describe this specific entity.

Massimo Rugge, Manuel Zorzi and Stefano Guzzinati describe 9,275 patients with SARS-CoV-2 infection (CV2+ve), 723 of whom (7.8%) had a cancer diagnosis. The proportion of patients hospitalized was higher among patients with cancer (56.6% versus 34.4% among other patients), and so was the proportion of deaths (14.7% versus 4.5%). The risk of adverse outcomes of SARS-CoV-2 infection was significantly higher for patients with cancer versus those without, particularly for males and older people. Breast cancer and hematological cancers were associated with a higher risk of both hospitalization and death. Lung cancer was associated with a fourfold risk of death due to SARS-CoV-2 infection. The authors insist that the clinical importance of these results warrants further investigation.

Are COVID-19 patients at risk of heart problems after surviving an illness? In a prospective observational cohort study, Eike Nagel and colleagues from the University of Frankfurt, Germany, evaluated cardiovascular magnetic resonance (CMR) images of 100 patients who were recovering from COVID-19 disease. A total of 78 patients (78%) had abnormal CMR findings, including raised myocardial native T1 (n = 73), raised myocardial native T2 (n = 60), myocardial late gadolinium enhancement (n = 32), and pericardial enhancement (n = 22). Endomyocardial biopsy in patients with severe findings revealed active lymphocytic inflammation. At the time of CMR, high-sensitivity troponin T was detectable (3 pg/mL or greater) in 71 patients recently recovered from COVID-19 (71%) and significantly elevated (13.9 pg/mL or greater) in 5 patients (5%). Of note, the median time interval between COVID-19 diagnosis and CMR was 71 (IQR: 64-92) days. The authors stress the need for ongoing investigation of the long-term cardiovascular consequences of COVID-19.

How much is COVID-19 associated with myocardial injury, possibly as the result of viral infection of the heart? Dirk Westermann and colleagues from the University Heart and Vascular Center in Hamburg, Germany, report on a series of 39 autopsies of patients with COVID-19 in whom pneumonia was the clinical cause of death in 35 of 39. SARS-CoV-2 was documented in 24 of 39 patients (61.5%) and viral load above 1000 copies per μg RNA in 16 of 39 patients (41.0%). A cytokine response panel consisting of 6 proinflammatory genes was increased in those 16 patients compared with 15 patients without any SARS-CoV-2 in the heart. In situ hybridization suggested that the most likely localization of SARS-CoV-2 was not in the cardiomyocytes but in interstitial cells or macrophages invading the myocardial tissue.

CLL patients have impaired humoral and cellular immune function. The authors describe the first large, disease-specific series in a defined cohort of hematologic cancer patients from 43 international centers. Of 198 CLL patients diagnosed with symptomatic COVID-19, 39% were treatment-naïve (“watch and wait”) while 61% received at least one CLL therapy. At a median follow-up of 16 days, the overall case fatality rate was 33%, while another 25% were still in hospital. Discover differences between “Watch and wait” and treated cohorts with regard to ICU admission, intubation, and mortality. CLL patients are at high risk of death.

The authors assessed the incidence of, and risk factors for, venous and arterial thrombotic events in patients with COVID-19 in 4 hospitals in New York City. Among 3334 consecutive patients, a thrombotic event occurred in 16.0%. 207 (6.2%) were venous (3.2% PE and 3.9% DVT) and 365 (11.1%) were arterial (1.6% ischemic stroke, 8.9% MI, and 1.0% systemic thromboembolism). All-cause mortality was 24.5% and was higher in those with thrombotic events (43.2% vs 21.0%). D-dimer level at presentation was independently associated with thrombotic events, consistent with early coagulopathy.

Sorry for being 40 days late to present this article published in June. As obesity is recognized as an independent risk factor for severe illness and death with COVID-19, a reminder of the players involved in the obesity pandemic is always helpful. The authors have a concise message: “Food industries around the world must immediately stop promoting, and governments must force reformulation of, unhealthy foods and drinks.” As food industries won’t stop promoting, governments must regulate them.

This review provides an assessment of prognostic factors in patients with diabetes and COVID-19. A poorer prognosis would be the consequence of the syndromic nature of diabetes: hyperglycemia, older age, comorbidities, and in particular hypertension, obesity, and cardiovascular disease. All would contribute to an increased risk.

The collateral damage is just as great. Using established transmission models, data indicate that in countries with a high burden of malaria, HIV and tuberculosis, COVID-19 related disruptions in care could lead to a loss of life-years of over 5 years, that is of the same order of magnitude as the direct impact from COVID-19. The authors estimate that deaths due to HIV, tuberculosis, and malaria over 5 years could increase by up to 10% due to HIV (mainly due to treatment interruptions), 20% to TB (less timely diagnosis and treatment of new cases), and 36% to malaria (interruption of planned net campaigns), respectively.

How will we deal with influenza next winter? Baloxavir marboxil (baloxavir) is a prodrug of the cap-dependent endonuclease inhibitor baloxavir acid and was approved as a single-dose treatment for uncomplicated influenza A and B in Japan and in the US in 2018. Among 752 household contacts of 545 index patients (96% influenza A) virus infection, the percentage in whom clinical influenza developed was significantly lower in the baloxavir group than in the placebo group (1.9% vs. 13.6%).

Sickle cell disease (SCD) disproportionately affects Black or African-American persons in the United States and can cause multisystem organ damage and reduced lifespan. Among 178 persons with SCD in the US who were reported to an SCD–coronavirus disease case registry, 122 (69%) were hospitalized and 13 (7%) died. According to the authors, this is alarming, given that the mean patient age was < 40 years. However, there may be bias toward more severe cases in this registry.

The pandemic has major implications for blood transfusion. There are uncertain patterns of demand, and transfusion institutions need to plan for reductions in donations and loss of crucial staff because of sickness and public health restrictions. This article provides a synthesis of the published literature and guidance during times of potential or actual shortage. However, a reduction in donor numbers has largely been matched by reductions in demand for transfusion.

Patients with autoimmune rheumatic disease might be more susceptible. Within 42 families with at least one member suffering from a rheumatic disease, COVID-19 was diagnosed in 27 (63%) of 43 patients with a rheumatic disease and in 28 (34%) of 83 of their family members with no rheumatic disease (adjusted odds ratio 2.68, 95% CI 1.14–6.27). Patients with rheumatic disease who were taking hydroxychloroquine had a lower risk of COVID-19 infection than patients taking other disease-modifying anti-rheumatic drugs (OR 0.09, 0.01–0.94).

COVID-19 is associated with hyperglycemic emergencies in COVID-19. In this case series of 35 patients from three hospitals in north London, UK, March 1–30, 2020, an over-representation of type 2 diabetes in patients presenting with diabetic ketoacidosis and long-lasting ketosis was observed. Findings suggest acute insulinopenia in patients with COVID-19 and with type 2 diabetes, which persisted up until the time of discharge in 30% of patients previously not insulin-treated. Moreover, the study sample, with almost half of patients of African background, had protracted ketonemia and ketoacidosis.

This registry-based cohort study from France has included 347 patients with MS with a confirmed or highly suspected diagnosis of COVID-19. In total, 73 patients (21.0%) had a COVID-19 severity score of 3 or more, and 12 patients (3.5%) died. Age, Expanded Disability Severity Scale score (EDSS; ranging from 0 to 10, with cutoffs at 3 and 6), and obesity were independent risk factors for severe COVID-19; there was no association found between exposure to disease-modifying therapies and severity.

Anticoagulants, or other antithrombotic agents such as antiplatelet drugs, might counteract the coagulopathic effects of COVID-19 resulting in improved outcomes. This small, matched-control study shows that this is probably not the case. Patients on aspirin (n=18), on clopidogrel (n=8), apixaban (n=12), warfarin (n=7) and some other drugs did not have a significantly different mortality risk to patients not taking these drugs. According to the authors, this could suggest these agents negate any potential increased mortality risk attributable to whichever disease the drugs had been prescribed, but further data on comorbidities is required to confirm this assertion.

The survey was conducted from 6 to 15 April, 2020 and filled out by 762 researchers from 52 countries. It captured opinions from across all career stages on how COVID-19 has severely impacted laboratory research (i.e., 65% of laboratories were mostly or completely shut). From the crippling of ongoing and planned clinical trials across the full breadth of stem cell research to the devastating loss of productivity for those researchers near career transitions, the survey revealed some of the bleak truths on the impact of COVID-19 in the stem cell community.

MMWR Morb Mortal Wkly Rep. ePub: 22 June 2020. Full-text: https://www.cdc.gov/mmwr/volumes/69/wr/mm6925e2.htm

National syndromic surveillance data has found that emergency department (ED) visits declined 42% during the early months of the pandemic. This report describes trends in ED visits for three acute life-threatening health conditions, immediately before and after declaration of the COVID-19 pandemic as a national emergency: in the 10 weeks following the declaration, ED visits declined 23% for heart attack, 20% for stroke, and 10% for hyperglycemic crisis. The substantial reduction might be explained by many pandemic-related factors including fear of exposure to COVID-19, unintended consequences of public health recommendations to minimize non-urgent health care, stay-at-home orders, or other reasons.

The authors review the evidence to date to see whether a history of hematological malignancy is associated with increased risk of COVID‐19. Results: Multivariable analysis does indicate that patients with hematological malignancy, especially those diagnosed recently, are at increased risk of death with COVID‐19 compared to the general population. The evidence that this risk is higher than for those with solid malignancies is conflicting. There is suggestive evidence from smaller cohort studies that those with myeloid malignancy may be at increased risk within the blood cancer population, but this needs to be confirmed through larger studies.

ACE inhibitors are not harmful, even in Denmark (one of the countries with the best epidemiological data). In a retrospective cohort study of 4,480 (!) patients diagnosed as having COVID-19, prior ACEI/ARB use, compared with no use, was not significantly associated with mortality (adjusted hazard ratio, 0.83). In a nested case-control study of a cohort of 494,170 patients with hypertension, use of ACEI/ARB, compared with use of other antihypertensive medications, was not significantly associated with COVID-19 diagnosis (adjusted hazard ratio, 1.05).

In this population-based cross-sectional study of 5,325 patients with out-of-hospital cardiac arrests in New York City, the number undergoing resuscitation was 3-fold higher during the COVID-19 period compared with the similar period in 2019. The authors report 2,653 excess out-of-hospital cardiac arrests (90% of these excess cases resulted in out-of-hospital deaths).

Question of the day. Answer: Some did so, yes. Out of the 2,102 participants of this survey, 34.7% reported drinking “more or much more” alcohol since the begin of the lockdown. Binary logistic regression analyses showed that especially low educated subjects and subjects with higher levels of perceived stress due to the lockdown were at risk of consuming more alcohol during the lockdown.

This study investigated the association between the outbreak of COVID-19 and PCI rates for ACS (Acute Coronary Syndromes) in the Campania region, which, with 5.8 million residents, represents ≈10% of the Italian population. The outbreak was associated with a decline in the number of PCIs for ACS by 32%. In the last 2 weeks of the observational period, PCIs for ACS were reduced by 50%. In comparison with PCI volumes for the same time in 2019, the decline in PCI rates was of a similar magnitude (between 36% and 38%).

There is no good time for surgery: In this cohort study of 41 surgical patients with COVID-19 and 82 tightly matched control patients, significant differences were documented regarding rates of early mortality and complications (odds ratios 9.5 and 5.0, respectively), mainly pneumonia and thrombotic complications, were significantly associated with COVID-19, and different models identified COVID-19 as the first variable associated with surgical complications. These data suggest that, whenever possible, surgery should be postponed in patients with COVID-19.

The authors analyzed over 700 lung transcriptome samples of patients with comorbidities associated with severe COVID-19 and found that ACE2 was highly expressed in these patients, compared to control individuals. Findings suggest that the higher expression of ACE2 in the lungs is associated with higher chances of developing a severe form of COVID-19, by facilitating SARS-CoV-2 entry into lung cells during the infection.

First large analysis on liver transplant recipients. At a median follow-up of 18 days, 16/100 died from COVID-19. Of note, mortality was observed only in patients aged 60 years or older (16/73) and was more common in male recipients than in female recipients. Although not statistically significant, more patients who were transplanted at least 2 years earlier died than did those who received their transplant within the past 2 years (15/82, 18% vs 1/21, 5%).

Ooops. They don’t trust their own authors (Mehra 2020). “Recently, substantive concerns have been raised about the quality of the information in that database”, editor Eric Rubin writes, washing NEJM’s hands in innocence. “We have asked the authors to provide evidence that the data are reliable. In the interim and for the benefit of our readers, we are publishing this Expression of Concern about the reliability of their conclusions.” Ok. Let’s wait and see what happens. But bad news because even in a journal like NEJM, bad data quality is possible.

This was the original work of concern. Bad news that we cannot trust it. This was our comment: “The first study analyzed a total of 8,910 COVID-19 patients (from 169 hospitals located in 11 countries) for whom discharge status was availably by March 29 (Mehra 2020). A total of 515 (5.8%) died in the hospital. Factors independently associated with an increased risk of in-hospital death were an age greater than 65 years (odds ratio, 1.93), coronary artery disease (2.70), heart failure (2.48; 95% CI, 1.62 to 3.79), cardiac arrhythmia (1.95; 95% CI, 1.33 to 2.86), chronic obstructive pulmonary disease (2.96; 95% CI, 2.00 to 4.40), and current smoking (1.79; 95% CI, 1.29 to 2.47). No increased risk was found for the use of ACE inhibitors (0.33; 95% CI, 0.20 to 0.54) or the use of ARBs (1.23; 95% CI, 0.87 to 1.74). Of note, use of either ACE inhibitors or statins was associated with better survival. However, these associations should be considered with extreme caution as the study design cannot exclude the possibility of confounding.”

31 people living with HIV (PLWH) were hospitalized for COVID-19. All patients were on antiretroviral therapy and virologically suppressed at the time of admission. One was mild (3%), 2 moderate (6.5%), 21 severe (60%) and 7 were critical (23%). At the time of analysis, 8 (25.8%) patients had died, 21 (67.7%) were alive and discharged and 2 (6.5%) were alive and hospitalized. Four deaths occurred in subjects over 65 years of age and 4 in patients between 50 and 65 years of age.

Cohort study from the USA, Canada, and Spain, analysing 928 cancer patients with COVID-19. Median age was 66 years (IQR 57–76) and the most prevalent malignancies were breast (21%) and prostate (16%). In total 121 (13%) patients had died. Beside general risk factors (age, male sex etc), independent factors associated with increased mortality were an ECOG status of 2 or higher and “active” cancer.

COVID-19 has halted many ongoing CNS clinical trials, especially in Alzheimer’s disease. While some of these trials will need to restart, others can re-start at different points with substantial protocol amendments. Authors propose the concept of mechanistic modeling-based virtual twin patients as a possible solution to harmonize the readouts from these complex and fragmented clinical datasets in a biologically relevant way.

The authors describe their way of taking care of the most vulnerable patient groups using telemedicine. They contacted 236/465 adult patients who received an allogeneic transplantation. Physicians felt confident about the management of patients using teleconsultations, and patients—reassured that they were not left alone while in quarantine—provided positive feedback on this approach.

Weekly prescriptions of PEP at a large center in London dropped from a peak of 54 (from Feb 17–23, 2020) to four (from March 30–April 5, 2020) during lockdown. The most obvious explanation for this decline is that individuals are engaging in less condomless sex during lockdown. However, this might also reflect people’s reluctance to travel during this period, which would mean that individuals are not accessing the PEP they require.

Comment of the copy-editor: “And might also mean, that if they have less desire to travel, are hooking up less, and perhaps less sex is happening.”

An important and large study, analysing 525 patients with IBD from 33 countries. Thirty-seven patients (7%) had severe COVID-19, and 16 patients died (3% case fatality rate). Risk factors for severe COVID-19 among IBD patients included increasing age, ≥2 comorbidities, systemic corticosteroids (aOR 6.9, 95% CI 2.3-20.5), and sulfasalazine or 5-aminosalicylate use (aOR 3.1, 95% CI 1.3-7.7). Maintaining remission with steroid-sparing treatments will be important in managing patients with IBD through this pandemic. However, a causal relationship cannot be definitively established. Notably, TNF antagonist treatment was not associated with severe COVID-19.

Review of the literature on thromboembolic events (TE) associated with COVID-19. The causation between the effects of ibuprofen and TE remains speculative. The role of ibuprofen on a vascular level remains unclear as well as whether ibuprofen is able to interact with SARS-CoV-2 through some mechanism. However, the authors recommend careful consideration to avoiding a high dosage of ibuprofen in subjects at particular risk of thromboembolic events.

This paper offers some recommendations on the optimization of leukemia management during high-risk COVID-19 periods. Instead of reducing patient access to specialized cancer centers and modifying therapies to ones with unproven curative benefit, there is more rationale for less intensive yet effective therapies that may require fewer visits to the clinic or hospitalizations.

The first larger case series in HIV-infected patients. No excess morbidity and mortality was found among symptomatic COVID-19 cases. As the majority (22/33) was treated with tenofovir, including those developing severe or critical disease, data indicate no or only minimal clinical effect of tenofovir against SARS-CoV-2. Four patients also were on darunavir when they developed COVID-19 symptoms.

Like SARS-CoV-2, influenza A viruses have been shown to use the ACE2 receptor. Using the linked electronic health care records of 5.6 million persons in the United Kingdom, authors have investigated the incidence of influenza among adults who received a prescription for an ACE inhibitor from 1998 through 2016. Main results: the use of ACE inhibitors and ARBs was associated with either no effect on the incidence of influenza or a lower incidence.

The hitherto largest retrospective study on the impact of type 2 diabetes (T2D) has carefully analyzed 7,337 cases of COVID-19 in Hubei Province, China, among them 952 with pre-existing T2D. The authors found that subjects with T2D required more medical interventions and had a significantly higher mortality (7.8% versus 2.7%; adjusted hazard ratio, 1.49) and multiple organ injury than the non-diabetic individuals. Well-controlled blood glucose was associated with markedly lower mortality (in-hospital death rate 1.1% versus 11.0%) compared to individuals with poorly controlled BG.

Patients on these drugs (n=43) had significantly lower concentrations of CRP (p = 0.049) and procalcitonin (p = 0.008) than patients on other antihypertensive drugs (n = 83). Furthermore, trends toward lower proportions of critical diseases (9.3% vs 22.9%; p = 0.061) and death rates (4.7% vs 13.3%; p = 0.216) were observed.

Baseline use of biologics is not associated with worse COVID-19 outcomes. A case series of 86 patients with immune-mediated inflammatory disease (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, psoriasis, inflammatory bowel disease, or related conditions) and symptomatic COVID-19, among them 62 (72%) receiving biologics or Janus kinase (JAK) inhibitors. The percentage of patients who were receiving biologics or JAK inhibitors at baseline was higher among the ambulatory patients than among the hospitalized patients. In contrast, hospitalization rates were higher in patients treated with oral glucocorticoids, hydroxychloroquine and methotrexate.

Best paper title of the day. Using a French Registry, the authors found a spectacular drop of 25% for admission due to STEMI between March 2019 and March 2020. The steep decline was found for both acute (< 24hrs) and late presentation (> 24 hrs) STEMI. But where did they go? According to the authors, explanations may be patients’ fear of coming to the hospital or disturbing busy caregivers, especially in the case of mild STEMI clinical presentation. Other hypothetical reasons are reduced air pollution, better adherence to treatment, limited physical activity or absence of occupational stress during lockdown. When will we ever learn?

Brand new information: smoking is not the best idea. However, this is particularly true in the current pandemic. Ever having smoked significantly and substantially increased pulmonary ACE2 expression by 25%. The significant smoking effect on ACE2 pulmonary expression may suggest an increased risk for viral binding and entry of SARS-CoV-2 in lungs of smokers.

Nice review. Data from 12 animal studies and from 12 human studies overwhelmingly imply that administration of ACEIs/ARBs does not increase ACE2 expression. Available evidence does not support the hypothesis that ACEI/ARB use increases ACE2 expression and the risk of complications from COVID-19. The authors conclude that patients being treated with ACEIs and ARBs should continue their use for approved indications.

Same idea: in this retrospective, multi-center study of 1128 adult patients with hypertension diagnosed with COVID-19, 188 patients taking ACEI/ARB were compared with 940 patients without using ACEI/ARB. Unadjusted mortality rate was lower in the ACEI/ARB group versus the non-ACEI/ARB group (3.7% vs. 9.8%). In a Cox model, after adjusting for age, gender, comorbidities, and in-hospital medications, the detected risk for all-cause mortality was lower in the ACEI/ARB group (adjusted HR 0.42; 95%CI, 0.19-0.92).
