Inflammatory Syndrome

Earlier in its course, SARS-CoV-2 was primarily identified to cause an acute respiratory illness in adults, the elderly and immunocompromised, while children were known to be afflicted with milder symptoms. However, since mid-April of 2020, latent effects of the virus have begun emerging in children and adolescents, which is characterised by a multisystem hyperinflammatory state; thus, the term Multisystem Inflammatory Syndrome in Children (MIS-C) was introduced by the WHO and CDC. The syndrome manifests itself approximately 4 weeks after COVID-19 infection, with symptoms mimicking Kawasaki Disease and Kawasaki Disease Shock Syndrome. Demographically, MIS-C peaks in children aged 5 to 14 years, with clusters in Europe, North and Latin America seen, later followed by Asia. Although the exact pathophysiology behind the syndrome is unknown, recent studies have proposed a post-infectious immune aetiology, which explains the increased levels of immunoglobulins seen in affected patients. Patient presentation includes, but is not limited to, persistent fever, rash, gastrointestinal symptoms and cardiac complications including myocarditis. These patients also have raised inflammatory markers including C reactive protein, ferritin and interleukin-6. In poorly controlled patients, the syndrome can lead to multiorgan failure and death. The mainstay of treatment includes the use of intravenous immunoglobulins, steroids, immune modulators and aspirin. Adjunct therapy includes the use of low molecular weight heparin or warfarin for long term anticoagulation. Currently very little is known about the syndrome, highlighting the need for awareness amongst healthcare workers and parents. Moreover, with increased cases of COVID-19 as a result of the second wave, it is essential to keep MIS-C in mind when attending patients with a past history of COVID-19 exposure or infection. Additionally, once these patients have been identified and treated, strict follow-up must be done in order carry out long term studies, and to identify possible sequelae and complications.

The Relationship

One of the most intriguing and mysterious phenomena observed during the COVID-19 pandemic has been represented by the occurrence of the multisystem inflammatory syndrome in children and adolescents (MIS-C). Patients with this condition have some overlapping signs and symptoms with those of Kawasaki disease (KD), but also display clinical features that are uncommon or less frequent in this illness, such as diarrhea, abdominal pain and myocardial involvement. The sickest patients may develop multiorgan failure and shock, usually due to myocarditis. Management is based on the administration of intravenous immunoglobulin, glucocorticoids and, in the most severe instances, anakinra. It is still debated whether MIS-C and KD represent different illnesses or are part of the same disease spectrum. The aim of the present review is to analyze critically the evidence in favor of the latter hypothesis and to provide the authors' personal interpretation of the relationship between the two conditions.

Abstract Objectives To describe the characteristics of children and adolescents affected by an outbreak of Kawasaki-like multisystem inflammatory syndrome and to evaluate a potential temporal association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Design Prospective observational study. Setting General paediatric department of a university hospital in Paris, France. Participants 21 children and adolescents (aged ≤18 years) with features of Kawasaki disease who were admitted to hospital between 27 April and 11 May 2020 and followed up until discharge by 15 May 2020. Main outcome measures The primary outcomes were clinical and biological data, imaging and echocardiographic findings, treatment, and outcomes. Nasopharyngeal swabs were prospectively tested for SARS-CoV-2 using reverse transcription-polymerase chain reaction (RT-PCR) and blood samples were tested for IgG antibodies to the virus. Results 21 children and adolescents (median age 7.9 (range 3.7-16.6) years) were admitted with features of Kawasaki disease over a 15 day period, with 12 (57%) of African ancestry. 12 (57%) presented with Kawasaki disease shock syndrome and 16 (76%) with myocarditis. 17 (81%) required intensive care support. All 21 patients had noticeable gastrointestinal symptoms during the early stage of illness and high levels of inflammatory markers. 19 (90%) had evidence of recent SARS-CoV-2 infection (positive RT-PCR result in 8/21, positive IgG antibody detection in 19/21). All 21 patients received intravenous immunoglobulin and 10 (48%) also received corticosteroids. The clinical outcome was favourable in all patients. Moderate coronary artery dilations were detected in 5 (24%) of the patients during hospital stay. By 15 May 2020, after 8 (5-17) days of hospital stay, all patients were discharged home. Conclusions The ongoing outbreak of Kawasaki-like multisystem inflammatory syndrome among children and adolescents in the Paris area might be related to SARS-CoV-2. In this study an unusually high proportion of the affected children and adolescents had gastrointestinal symptoms, Kawasaki disease shock syndrome, and were of African ancestry.

Inflammatory Syndrome

COVID-19 is generally a benign or asymptomatic infection in children, but can occasionally be severe or fatal. Delayed presentation of COVID-19 with hyperinflammation and multi-organ involvement was recently recognized, designated the Multisystem Inflammatory Syndrome in Children (MIS-C). Six children with MIS-C with molecular and serologic evidence of SARS-CoV-2 infection were admitted to our hospital between May 5, 2020 and June 25, 2020. All had fever and weakness; 4/6 presented with gastrointestinal symptoms. Two children had features of complete Kawasaki disease, 3 had incomplete Kawasaki disease, while 1 had terminal ileitis with delayed onset of circulatory shock. Treatment consisted of intravenous immunoglobulin and aspirin for Kawasaki-like disease. Remdesivir, corticosteroids, and infliximab were used when indicated. Median hospitalization was 7 days. Immediate treatment resulted in rapid clinical improvement. In children presenting with hyperinflammatory syndromes without cardiac manifestations, testing for SARS-CoV-2 RNA and antibodies, with close cardiac monitoring should be pursued due to the manifold presentations of SARS-CoV-2 infection in children.

Abstract Background Although symptoms and signs of COVID-19 (Coronavirus disease 2019) in children are milder than adults, there are reports of more severe cases which were defined as pediatric inflammatory multisystem syndrome (PIMS). The purpose of this report was to describe the possible association between COVID-19 and PIMS in children. Methods From 28 March to 24 June 2020, 10 febrile children were admitted with COVID-19 infection showing characteristics of PIMS in Buali tertiary hospital of Sari, in Mazandaran province, northern Iran. Demographic and clinical characteristics, laboratory and imaging findings, and therapeutic modalities were recorded and analyzed. Results The mean age of the patients was 5.37 ± 3.9 years (13 months to 12 years). Six of them were boys. Kawasaki disease, myocarditis, toxic shock syndrome, appendicitis, sepsis, urosepsis, prolonged febrile seizure, acute hemorrhagic edema of infancy, and COVID-19-related pneumonia were their first presentation. All of them had increased C-reactive protein levels, and most of them had elevated erythrocyte sedimentation rate, lymphopenia, anemia, and hypoalbuminemia. Three of them had thrombocytopenia(PLT < 106). Six of them were serologically or polymerase chain reaction positive for COVID-19, and 4 of them were diagnosed as COVID-19 just by chest computed tomography scan. Most of the patients improved without a residual sequel, except one who died with multiorgan failure and another case was discharged with a giant coronary aneurysm. Conclusions Children with COVID-19 may present symptoms similar to Kawasaki disease and inflammatory syndromes. PIMS should be considered in children with fever, rash, seizure, cough, tachypnea, and gastrointestinal symptoms such as vomiting, diarrhea, and abdominal pain.

AbstractBackgroundKawasaki disease is an acute systemic vasculitis. Cardiac complications are frequent and include endothelial dysfunction in patients with coronary anomalies. Thus far, endothelial dysfunction in patients with no coronary lesions is poorly understood. Our aim was to access the vascular function in adolescents and young adults long term after Kawasaki disease, but without coronary aneurysms or any other cardiac risk factors.MethodsWe carried out a single-centre prospective study in a Portuguese population. We evaluated two groups of subjects: (1) Kawasaki disease patients over 11 years of age, diagnosed >5 years ago, with no coronary lesions or any other risk factors for cardiovascular disease; (2) control group of individuals without cardiovascular risk factors. Patients and controls were clinically assessed. Endo-PAT and carotid intima-media thickness assessment were performed to determine vascular function.ResultsIn total, 43 Kawasaki disease patients were assessed and compared with 43 controls. Kawasaki disease patients presented a decreased reactive hyperaemia index compared with controls (1.59±0.45 versus 1.98±0.41; p<0.001). Augmentation index was similar in both groups (−4.5±7 versus −5±9%; p 0.6). The mean carotid intima-media thickness was not significantly increased in the Kawasaki disease group. There were no statistically significant changes with regard to laboratory data.ConclusionsChildren with Kawasaki disease may have long-term sequelae, even when there is no discernible coronary artery involvement in the acute stage of the disease. Further research is needed to assess whether known strategies to improve endothelial function would bring potential benefits to Kawasaki disease patients.

Abstract Multisystem Inflammatory Syndrome in Children (MIS-C) is characterized by an inflammation with fever, elevated inflammatory markers, conjunctivitis, rash, impaired coagulation, gastrointestinal symptoms and cardiac abnormalities that may progress to multiorgan failure. The presence of a positive COVID-19 antigen via a PCR test, serological testing for antibodies or close contact with a person diagnosed with COVID-19 helps differentiate MIS-C from other diseases. Gastrointestinal symptoms are recognized to be associated with COVID-19 infection or MIS-C in children, presenting as abdominal pain, gastrointestinal infection with watery stools, appendicitis, ileitis, pancreatitis and hepatitis, confusing the diagnosis with other gastrointestinal diseases. In this case report, we describe an 11 year old boy with MIS-C, who presents acute phlegmona of the appendix for which he undergoes appendectomy, accompanied with acute pancreatitis. These manifestations of MIS-C in our patient resolved without additional complications after a 2 month follow up. We call attention to MIS-C presenting in pediatric patients with fever and abdominal pain which might be caused by appendicitis and pancreatitis, and we recommend abdominal imaging and additional laboratory investigation to promote earlier diagnosis.

The prevalence of multisystem inflammatory syndrome in children (MIS-C) has increased since the coronavirus disease 2019 (COVID-19) pandemic started. This study was aimed to describe clinical manifestation and outcomes of MIS-C associated with COVID-19. This systematic review and meta-analysis were conducted on all available literature until July 3rd, 2020. The screening was done by using the following keywords: (“novel coronavirus” Or COVID-19 or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or coronavirus) and ("MIS-C" or "multisystem inflammatory" or Kawasaki). Data on gender, ethnicity, clinical presentations, need for mechanical ventilation or admission to intensive care unit (ICU), imaging, cardiac complications, and COVID-19 laboratory results were extracted to measure the pooled estimates. Out of 314 found articles, 16 articles with a total of 600 patients were included in the study, the most common presentation was fever (97%), followed by gastrointestinal symptoms (80%), and skin rashes (60%) as well as shock (55%), conjunctivitis (54%), and respiratory symptoms (39%). Less common presentations were neurologic problems (33%), and skin desquamation (30%), MIS-C was slightly more prevalent in males (53.7%) compared to females (46.3%). The findings of this meta-analysis on current evidence found that the common clinical presentations of COVID-19 associated MIS-C include a combination of fever and mucocutaneous involvements, similar to atypical Kawasaki disease, and multiple organ dysfunction. Due to the relatively higher morbidity and mortality rate, it is very important to diagnose this condition promptly.

Inflammatory Syndrome

During the COVD-19 pandemic, some pediatric patients in many countries around the world experienced a syndrome resembling a severe Kawasaki disease (KD), often accompanied by shock. Due to the incomplete signs of the classic KD in the era before the present pandemic, in many publications from European countries and the United States, this condition was called «multisystem inflammatory syndrome in children – MIS-C» or «hyperinflammatory shock» or «Kawasaki-like syndrome». This syndrome with a new coronavirus infection is characterized by refractory fever, frequent gastrointestinal symptoms, heart damage (including coronary dilation in some patients, and acute left ventricular failure in the majority), increased ESR and CRP levels, neutrophilia, extremely high troponin levels, increased ferritin, AST, ALT, lactate dehydrogenase, creatine phosphate kinase, interleukin-6 and interleukin-10, coagulopathy with an increase in D-dimer and fibrinogen, thrombocytopenia, sometimes procalcitonin increase. The manifestations of a cytokine storm may meet the criteria for secondary hemophagocytic syndrome. The mechanism of myocardial damage remains unclear. Treatment with high-dose intravenous immunoglobulin is effective, and in the presence of signs of hemophagocytic syndrome, dexamethasone or methylprednisolone. Further research is needed to understand the pathogenesis, resemblance and differences of this syndrome with classic KD, understanding of heart injuiry and early recognition for the need of urgent care.

Introduction: Following the SARS-CoV-2 pandemic peak, children suffering from a multiorgan inflammatory disease that often leads to shock have been reported. This condition shares features with Kawasaki disease, but its etiopathogenesis is unknown. Hypothesis: We aimed to describe presentation and hospital course for this pediatric inflammatory multisystemic syndrome associated with COVID-19 (PIMS-TS). Methods: Data were collected from a retrospective review of children from 33 participating European, Asian and American sites. Results: We included 183 patients (109 males, 59·6%) with PIMS-TS, at a mean age of 7·0 (±4·7) years. Fifty-six (30·6%) had black ethnicity and obesity was present in 48 (26·2%) cases. Overall, 114/183 (62·3%) had biological evidence of current or recent SARS-CoV-2 infection. At admission, all presented with fever, 117/183 (63·9%) with gastrointestinal symptoms and 79/183 (43·2%) with shock, that was associated with more frequent black ethnicity, higher inflammatory markers and more cardiac involvement. Twenty-seven patients (14·7%) fulfilled criteria for Kawasaki disease. They were younger with no shock, fewer gastrointestinal, cardio-respiratory and neurological symptoms. Among the remaining PIMS-TS patients, 77 (49·3%) had mainly fever and inflammation with less cardiac involvement. For the entire cohort of 183 patients, the mean duration of admission was 8·6 (±5·6) days. Inotropic support, mechanical ventilation and ECMO were indicated in 72 (39·3%), 43 (23·5%) and 4 (2·2%) patients, respectively. Three patients (1·6%) died. A shorter duration of symptoms before admission was a risk factor for worse outcome and for ECMO/death, with 63% increased risk per day reduction (95%CI 0·39-0·93, p=0·03) and with 51·4% increased risk per day reduction (95%CI 0·36-0·9, p=0·03), respectively. Conclusions: We describe the first largest international series of children with PIMS-TS. Life-threatening shock is a common presentation. A shorter duration of symptoms prior to admission characterizes the fulminant form of the disease with potentially worse outcome.

Coronavirus disease 19 (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus which emerged in Wuhan, China in 2019, and from there spread to other parts of mainland China and around the world. The virus spreads mainly through respiratory droplets produced when an infected person coughs, sneezes, or speaks. On average, the time from exposure to SARS-CoV-2 to the appearance of symptoms is 5–6 days but can range from 1–14 days. Asymptomatic infections with SARS-CoV-2 can occur. In those with symptoms, most people (approx. 80%) will experience a mild to moderate respiratory illness and recover without hospital management. Adults 65 years of age and older, and individuals of any age with underlying medical conditions, are at increased risk for severe COVID-19 and death. Complications include respiratory failure, acute respiratory distress syndrome, sepsis/septic shock, thromboembolism, multiorgan failure and death. In rare cases, children and adults can develop a severe inflammatory syndrome a few weeks after SARS-COV-2 infection. Vaccines are available to help prevent COVID-19 disease; by August 2021, 7 vaccines had been authorized for use by the WHO to prevent COVID-19 caused by SARS-CoV-2, with others approved by country regulatory authorities.
