Kawasaki-like syndrome in children (March/April 2020)

A new twist in this new pandemic: at the end of March 2020, Jones et al. described the case of a six-month-old baby girl with fever, rash and swelling characteristic of a rare pediatric inflammatory condition, Kawasaki syndrome (Jones 2020). The child is treated according to treatment guidelines with a single dose of 2g/kg intravenous immunoglobulin and high dose acetylsalicylic 20mg/kg four times daily. The fever breaks within hours.

A month later, on 27 April, the National Health Service (NHS) sends an email alert to members of the British Paediatric Critical Care Society (PICS) highlighting “a small rise in the number of cases of critically ill children presenting with an unusual clinical picture.” Many of these children have tested positive for COVID-19, while some had not. The alert indicates that “the cases have in common overlapping features of toxic shock syndrome and atypical Kawasaki disease with blood parameters consistent with severe COVID-19 in children. Abdominal pain and gastrointestinal symptoms have been a common feature as has cardiac inflammation”, (see the PICS statement).

A few days later, Sylvain Renolleau, head of the intensive care unit at Necker hospital, Paris, reports more than 20 children and adolescents 3 to 17 years old hospitalized in intensive care. The first cases were seen around 15 April. Symptoms included abdominal pain, diarrhea and vomiting, sometimes fever, myocarditis, and a strong inflammatory syndrome. Although not all children tested positive for SARS-CoV-2, all seem to have been in contact with the virus. No deaths have been reported so far. At the end of April, nearly 100 cases had been found in children in France, Great Britain, Italy, Spain, Switzerland and the United States.

On 1 May 2020, the Royal College of Paediatrics and Child Health released guidance describing a systemic inflammatory response sharing “common features with other pediatric inflammatory conditions including: Kawasaki disease, staphylococcal and streptococcal toxic shock syndromes, bacterial sepsis, and macrophage activation syndromes (Royal College of Paediatrics and Child Health 2020).” On 4 May, New York City’s Department of Health issued a similar alert (NYC Health 2020). Two days later, 64 cases were reported from New York (New York Department of Health 2020).

Kawasaki Disease

Kawasaki disease (KD) is an acute-onset systemic vasculitis of medium-sized vessels that mostly affects infants and toddlers (Hedrich 2017).

The first English-language report of 50 patients goes back to Tomisaku Kawasaki in 1974 (Kawaski 1974, Burns 2000). The KD incidence is much higher in Northeast Asian countries including Japan, South Korea, China, and Taiwan, 10–30 times higher than that of KD in North America and Europe (see the world map in Kim GB 2019).

More than 90% of children were less than 5 years old in a study from Inner Mongolia (Zhu 2015). Untreated, KD leads to coronary artery aneurysms in around 25% of cases (don’t miss this paper: McCrindle 2017). The diagnosis of “classic KD” is based on the presence of ≥5 days of fever plus four out of five diagnostic criteria including erythema of the lips or mouth, trunk rash, swelling or erythema of the hands or feet, conjunctivitis, and lymph node swelling (see the detailed discussion in McCrindle 2017).

Prompt diagnosis is essential, immune globulin being the mainstay of initial treatment. Even in these COVID-19 times, physicians should keep an eye out for KD in all children with prolonged fever, especially in those younger than 1 year (Harasheh 2020).

The cause of KD remains unknown. Some lines of evidence point to a post-infectious trigger causing hyperreaction of the immune system (Dietz 2017) and an association between viral respiratory infections and KD (Jordan-Villegas 2010, Kim JH 2012, Turnier 2015). The primarily winter-spring KD seasonality and well-documented Japanese epidemics with wave-like spread also support an infectious trigger (Rowley 2018).

The Future

It is still unknown if there is a correlation between the cases described above and COVID-19. If there is a correlation, it is unclear whether COVID-19-associated inflammatory disorder and Kawasaki disease are identical (COVID-19-associated cases seem to have more severe abdominal pain, nausea and vomiting; those with severe shock are often older than the typical Kawasaki patients; and in Kawasaki cases, heart vessels seem to be more involved).


  • A new Kawasaki-like syndrome may be emerging in children of all ages.
  • The syndrome is rare.
  • This syndrome may be related to SARS-CoV-2 but could as well be related to a different infectious pathogen with similar characteristics.
  • So far, little is known about the new syndrome.
  • To be remembered: serious COVID-19 complications are very rare among children. Throughout Europe, SARS-CoV-2 has caused very few victims among children. In Britain, only 9 children aged 0 to 19 have died after testing positive for coronavirus (0.05% of the 21,678 deaths recorded at the end of April).

According to this review of 24 studies, children appear to be less affected by COVID-19 than adults by observed rate of cases in large epidemiological studies. Limited data on attack rate indicate that children are just as susceptible to infection. Data on clinical outcomes are scarce but include several reports of asymptomatic infection and a milder course of disease in young children, though radiological abnormalities have been noted.

From 177 infected pediatric patients, 44 were hospitalized and 9 were critically ill. Of these, 6/9 were adolescents and young adults > 15 years of age. Although asthma was the most prevalent underlying condition overall, it was not more common among patients with severe disease. There were no significant differences in the presence of underlying conditions overall or any specific underlying diagnosis. Asthma exacerbation is not the primary determinant of more severe disease.

Outcome of 427 pregnant women admitted to hospital with confirmed SARS-CoV-2 infection between 1 March 2020 and 14 April 2020: Most (but not all) outcomes were good, and transmission of SARS-CoV-2 to infants was uncommon. Of note, there were 233 (56%) women from black or other ethnic minority groups, 281 (69%) were overweight or obese, 175 (41%) were aged 35 or over, and 145 (34%) had pre-existing comorbidities. 266 (62%) women gave birth or had a pregnancy loss; 196 (73%) gave birth at term. Forty one (10%) women admitted to hospital needed respiratory support, and five (1%) women died. Twelve (5%) of 265 infants tested positive for SARS-CoV-2 RNA, six of them within the first 12 hours after birth.

Of 82 pregnant patients, 4 presented with severe COVID-19 symptoms, including 1 with concomitant preeclampsia; all 4 underwent cesarean delivery and required ICU admission. Among patients with mild symptoms at presentation, all patients with a vaginal birth had excellent outcomes. In contrast, 13.5% of women undergoing cesarean delivery had severe maternal outcomes and 21.6% had clinical deterioration. Women undergoing cesarean delivery may have been at higher risk of adverse outcomes, but after adjusting for confounding factors, cesarean birth remained independently associated with an increased risk of clinical deterioration. The physiological stress induced by surgery is known to increase postpartum maternal complications

Stewart DJ, Hartley JC, Johnson M, et al. Renal dysfunction in hospitalised children with COVID-19. Lancet Child Adol Health. June 15, 2020. Full-text:  https://doi.org/10.1016/S2352-4642(20)30178-4

Of 52 hospitalized children, 24 (46%) had elevated serum creatinine, and 15 (29%) met the diagnostic criteria for acute kidney injury (AKI). Most AKI cases occurred in those admitted to the pediatric ICU (93%), and in those with pediatric inflammatory multisystem syndrome temporarily associated with SARS-CoV-2 (PIMS-TS; 73%). This underlines the importance of renal function surveillance in all hospitalised pediatric cases of COVID-19, while simultaneously avoiding factors that exacerbate kidney injury, such as hypovolemia and the use of nephrotoxic drugs. According to the authors, standard care should involve screening for nephritis and follow-up for long-term sequelae of acute kidney injury, such as hypertension and proteinuria.

The median age was 8.3 years, 115 patients (62%) were male, 135 (73%) had previously been healthy, 131 (70%) were positive for SARS-CoV-2 by RT-PCR or antibody testing. Detailed analysis of clinical manifestation revealed the gastrointestinal system (92%), cardiovascular (80%), hematologic (76%), mucocutaneous (74%), and respiratory involvement (70%). In total 148 patients (80%) received intensive care, 37 (20%) received mechanical ventilation, and 4 (2%) died. Coronary-artery aneurysms were documented in 15 patients (8%), and Kawasaki’s disease–like features were documented in 74 (40%).

No differences between adults and children. The authors isolated culture-competent virus in vitro from 12 (52%) of 23 SARS-CoV-2–infected children; the youngest was 7 days old. SARS-CoV-2 viral load and shedding patterns of culture-competent virus in the 12 symptomatic children resembled those in adults. Therefore, transmission of SARS-CoV-2 from children is plausible.

Another large cohort of 95 patients with a multi-system inflammatory syndrome in children (MIS-C), reported to the New York State Department of Health. Detailed analysis of the characteristics: Elevated levels of C-reactive protein, d-dimer, and troponin were found in 100%, 91%, and 71% of the patients, respectively; 53% had evidence of myocarditis, 80% were admitted to an intensive care unit, and 2 died.

A case series of 4 children with COVID-19 and neurological symptoms is described. Symptoms included encephalopathy, headaches, brainstem and cerebellar signs, muscle weakness, and reduced reflexes. All 4 patients had signal changes in the splenium of the corpus callosum on neuroimaging and required intensive care admission for the treatment of COVID-19 pediatric multisystem inflammatory syndrome.

First study on detection and decline over time of antibodies in infants born to women with COVID-19. Among the 24 infants born to women with COVID-19, 15 (62.5%) had detectable IgG and 6 (25.0%) had detectable IgM; nucleic acid test results were all negative. Among 11 infants tested at birth, all had detectable IgG and 5 had detectable IgM. IgG titers with positive IgM declined more slowly than those without.

Of 100 children (median age 3 years), 21% were asymptomatic, 58% had mild disease, 19% had moderate disease, 1% had severe disease, and 1% were in critical condition. The incidence of transmission through apparent exposure to a family cluster was lower than that in other cohorts, possibly because of the late lockdown in Italy.

Lancet Child Adolesc Health July 09, 2020. Full-text: https://doi.org/10.1016/S2352-4642(20)30215-7

In 78 cases of PIMS-TS reported by 21 of 23 centres in the UK, male patients (67%) and those from ethnic minority backgrounds (78%) were over-represented. In total, 36 (46%) were invasively ventilated and 28 (36%) had evidence of coronary artery abnormalities (18 aneurysms and ten echogenicity). Three children needed ECMO and two children died.

Pregnancy outcomes at St George’s University Hospital, London, were evaluated in two periods: from October 2019 to January 2020 and from February to June 2020. The incidence of stillbirth was significantly higher during the pandemic period (9.31 per 1000) than during the pre-pandemic period (2.38 per 1000). Of note, the increase in stillbirths may have also resulted from indirect effects such as reluctance to attend hospital when needed, fear of contracting infection, or not wanting to add to the National Health Service burden. Changes in obstetric services may have played a role secondary to staff shortages or reduced antenatal visits, ultrasound scans, and/or screening.

Transmission of COVID-19 is unlikely to occur if correct hygiene precautions are undertaken. This recommendation is confirmed via an observational cohort study in neonates born at three hospitals in New York City to mothers positive for SARS-CoV-2 at delivery. Of a total of 1481 deliveries, 116 (8%) mothers tested positive for SARS-CoV-2; 120 neonates were identified. All neonates were tested at 24 h of life and none were positive for SARS-CoV-2. All mothers were allowed to breastfeed. Of the neonates who completed follow-up at day 5–7 and day 14 of life, none was infected. The message: allowing neonates to room in with their mothers and direct breastfeeding are safe procedures when paired with effective parental education of infant protective strategies.

Multisystem inflammatory syndrome in children (MIS-C) is a rare but severe condition that has been reported approximately 2–4 weeks after the onset of COVID-19 in children and adolescents. Now Shana Godfred-Cato and colleagues report 570 US MIS-C patients who met the CDC case definition as of July 29. A total of 203 (35.6%) of the patients had a clinical course consistent with previously published MIS-C reports, characterized predominantly by shock, cardiac dysfunction, abdominal pain, and markedly elevated inflammatory markers, and almost all had positive SARS-CoV-2 test results (Class 1). The remaining 367 (64.4%) of MIS-C patients (Class 2 and 3) had manifestations that appeared to overlap with acute COVID-19 or had features of Kawasaki disease. 364 patients (63.9%) required care in an intensive care unit ICU. Ten patients (1.8%) died. The median patient age was 8 years (range = 2 weeks–20 years). Approximately two thirds of the children had no preexisting underlying medical conditions.

MMWR Morb Mortal Wkly Rep. ePub: 7 August 2020. Full-text: http://dx.doi.org/10.15585/mmwr.mm6932e3

COVID-NET conducts population-based surveillance for laboratory-confirmed COVID-19–associated hospitalizations in 14 US states. From March 1 to July 25, 576 children hospitalized with COVID-19 were reported to COVID-NET. Although the cumulative COVID-19–associated hospitalization rate among children was low compared with that among adults, weekly hospitalization rates in children increased during the surveillance period. Children can develop severe COVID-19 illness; during the surveillance period, one in three children was admitted to the ICU. Hispanic and black children had the highest rates of COVID-19–associated hospitalization.

The authors report on 45 newborns born to SARS-CoV-2 positive mothers. The majority of positive mothers, 27 (60%), were asymptomatic. Mothers were encouraged to provide skin-to-skin care and breastfeeding. All the newborns were tested for SARS-CoV-2; only 3 (6.6%) tested positive (see Figure 1). Those three newborns were monitored until two consecutive tests obtained at least 24 h apart were negative and they remained asymptomatic, thus suggesting transient colonization.

Children and adolescents make up only a small percent of all COVID-19 cases. However, in the past months, reports from Europe, North America, Asia, and Latin America described children and adolescents with COVID-19-associated multisystem inflammatory conditions which are both similar and distinct from other well described inflammatory syndromes in children, including Kawasaki disease, Kawasaki disease shock syndrome, and toxic shock syndrome. In this review, Zulfiqar Bhutta and colleagues provide an overview of the epidemiology, causes, clinical features, and current treatment protocols.

Lael Yonker and colleagues from Massachusetts General Hospital in Boston postulate that children may be a potential source of contagion in the SARS-CoV-2 pandemic in spite of milder disease or lack of symptoms. A total of 192 children (mean age 10.2 years) were enrolled, among them 49 children with acute SARS-CoV-2 infection. Nasopharyngeal viral load was highest in children in the first 2 days of symptoms, significantly higher than hospitalized adults with severe disease. Age did not impact viral load, but younger children had lower ACE2 expression.

In a post-mortem analysis of cardiac tissue by electron microscopy, Marisa Dolhnikoff et al. report identified spherical viral particles of 70 – 100 nm in diameter, consistent in size and shape with the Coronaviridae family, in the extracellular compartment and within several cell types—cardiomyocytes, capillary endothelial cells, endocardium endothelial cells, macrophages, neutrophils, and fibroblasts. The autopsy showed myocarditis, pericarditis, and endocarditis, with intense and diffuse tissue inflammation, and necrosis of cardiomyocytes. The authors conclude that clinical, echocardiographic, and laboratory findings strongly indicate that heart failure was the main determinant of the fatal outcome.

Congenital infection is rare. This comprehensive literature search (up until June 9, 2020) identified 1,992 pregnant women, of which 1,125 (56.5%) gave birth to 1141 neonates. Of these, 58 neonates were reported with SARS-CoV-2 infection. Postpartum acquisition was the commonest mode of infection, and only 4 had a congenital infection.

In this cross-sectional study of 216 children hospitalized with COVID-19 in Wuhan, China, 49 (22.7%) had (mild, self-healing) ocular manifestations, including conjunctival discharge, eye rubbing, and conjunctival congestion. Children with systemic symptoms or cough were more likely to develop ocular symptoms.

Estimating the epidemic in children. Overall, the prevalence of positive SARS-CoV-2 test results in children without symptoms at 28 children’s hospitals across the US was low (0.65%, 95% CI, 0.47%-0.83%): Only 250 of 33,041 children were PCR positive through 29 May 2020. Of note, there was a strong association between prevalence and contemporaneous weekly incidence of COVID-19 in the general population.

Data from the BRAVE Kids study, Matthew Kelly, Jillian Hurst and colleagues describe the clinical and epidemiological characteristics of 382 children and adolescents who had close contact with a SARS-CoV-2-infected individual. Children aged 6 – 13 years were frequently asymptomatic (39%) and had respiratory symptoms less often than younger children (29% vs 48%) or adolescents (29% vs 60%). Compared to children aged 6 – 13 years, adolescents more frequently reported influenza-like (61% vs 39%), gastrointestinal (27% vs 9%; p = 0.002), and sensory symptoms (42% vs 9%), and had more prolonged illnesses [median (IQR) duration: 7 (4, 12) vs 4 (3, 8) days]. The authors also found that SARS-CoV-2-infected children were more likely to be Hispanic (p < 0.0001), less likely to have asthma (p = 0.005), and more likely to have an infected sibling contact (p = 0.001) than uninfected children.

In this prospective observational cohort study, Malcolm Semple, Olivia Swann and colleagues report on 651 children and young people aged less than 19 years. Median age was 4.6 years, 35% (225/651) were under 12 months old. 18% (116/632) of children were admitted to critical care. Six patients died in hospital, all of whom had profound comorbidity. The 11% (52/456) who met the WHO MIS-C criteria were five times more likely to be admitted to critical care. Ethnicity seems to be a factor in both critical care admission and MIS-C. The authors also identified a systemic mucocutaneous-enteric symptom cluster in acute cases that shares features with MIS-C. They suggest that the WHO MIS-C preliminary case definition be refined.

How many pediatric SARS-CoV-2 cases would doctors miss if they focused on only testing symptomatic patients? Maybe up to 90%, say Jong-Hyun Kim, Eun Hwa Choi, Mi Seon Han and colleagues from Korea. In this case series of children with COVID-19, 20 children (22%) were asymptomatic during the entire observation period. Among 71 symptomatic cases, only 6 (9%) were diagnosed at the time of symptom onset while 47 children (66%) had unrecognized symptoms before diagnosis and 18 (25%) developed symptoms after diagnosis. The authors conclude that there is no other good alternative to extensive testing for early detection of SARS-CoV-2 infection.

Summary of the clinical symptoms (91 patients):

Asymptomatic 22%
Cough 41%
Fever > 38º C 30%
Sore throat 29%
Runny nose 27%
Diarrhea 12%
Loss of sense of taste 12%

Fifty-one percent had “mild” disease, 22% “moderate” disease and 2% “severe” disease. No patient required intensive care.

Roberta DeBiasi and Meghan Delaney comment on the previous study and underline the three “take-home points”:

  1. Not all infected children have symptoms, and even those with symptoms are not necessarily recognized in a timely fashion.
  2. Duration of symptoms in symptomatic infected pediatric patients varies widely.
  3. Virus was detectable for a mean of 17.6 days overall and was detectable for a prolonged period of time in all cohorts of children, whether symptoms were present or not. (Detectability does not mean infectivity in all cases, though.)

Important summary in view of the current school re-openings.

Should pregnancy shield women from depression and anxiety in these COVID times? The authors enrolled 544 pregnant women and 315 non-pregnant women. In this study, 5.3%, 6.8%, 2.4%, 2.6%, and 0.9% of pregnant women were identified to have symptoms of depression, anxiety, physical discomfort, insomnia, and post-traumatic stress disorder (PTSD), respectively. However, the corresponding prevalence rates among non-pregnant women were 17.5%, 17.5%, 2.5%, 5.4%, 5.7%, respectively. In China, pregnant women seemed to have an advantage of facing mental problems caused by COVID-19.

Among 263 initial infants enrolled in the PRIORITY study, adverse outcomes, including preterm birth, NICU admission, and respiratory disease did not differ between those born to mothers testing positive for SARS-CoV-2 (n=184) and those born to mothers testing negative (n=79). No pneumonia or lower respiratory tract infection was reported through 6-8 weeks of age. Among infants born to mothers who tested positive for SARS-CoV-2, the estimated incidence of a positive infant was low at 1.1% (0.1%, 4.0%), and infants had minimal symptoms. Overall, these results are reassuring and suggest that infants born to mothers infected with SARS-CoV-2 generally do well in the first 6-8 weeks after birth.
