Sumario: | OBJECTIVES: To study (1) epidemiological factors, clinical profile and outcomes of COVID-19 related multisystem inflammatory syndrome in children (MIS-C), (2) clinical profile across age groups, (3) medium-term outcomes and (4) parameters associated with disease severity. DESIGN: Hospital-based prospective cohort study. SETTING: Two tertiary care centres in Kerala, India. PARTICIPANTS: Diagnosed patients of MIS-C using the case definition of Centres for Disease Control and Prevention. STATISTICAL ANALYSIS: Pearson χ(2) test or Fisher’s exact test was used to compare the categorical variables and independent sample t-test or Mann-Whitney test was used to compare the continuous variables between the subgroups categorised by the requirement of mechanical ventilation. Bonferroni’s correction was used for multiple comparisons. RESULTS: We report 41 patients with MIS-C, mean age was 6.2 (4.0) years, and 33 (80%) were previously healthy. Echocardiogram was abnormal in 23 (56%), and coronary abnormalities were noted in 15 (37%) patients. Immunomodulatory therapy was administered to 39 (95%), steroids and IVIg both were used in 35 (85%) and only steroids in 3 (7%) patients. Intensive care was required in 36 (88%), mechanical ventilation in 8 (20%), inotropic support in 21 (51%), and 2 (5%) patients died. Mechanical ventilation requirement in MIS-C was associated with hyperferritinaemia (p=0.001). Thirty-seven patients completed 3 months follow-up by April 2021, of whom 6 (16%) patients had some residual echocardiographic changes. CONCLUSIONS: Patients with MIS-C in our cohort had varied clinical manifestations ranging from fever with mild gastrointestinal and mucocutaneous involvement to fatal multiorgan dysfunction. Immediate and medium-term outcomes remain largely excellent except for the echocardiographic sequelae in a few patients which are also showing a resolving trend. Hyperferritinaemia was associated with the requirement of mechanical ventilation. |
