Mortality indicators with clinical profile of multisystem inflammatory syndrome in children during SARS-CoV-2 second wave in India: A tertiary referral center experience.

Abstract

Post-COVID-19 cases are being reported with features of hyperinflammatory state causing multiple system dysfunctions in previously healthy children. To describe clinical characteristics, laboratory, and radiological profile of children affected with COVID-19-related multisystem inflammatory syndrome postsecond wave in India and compare them with respect to adverse outcome. This prospective, observational study was conducted in the department of pediatrics of a tertiary care center in Eastern India over a period of 3 months. Demographic data, clinical details, biochemical parameters, and treatment with clinical outcome were recorded. Children who survived the clinical course were compared with those died during hospital stay. Thirty-five children with a median age of 4.8 (3.9) years were included who were admitted between June 16 and September 15, 2021. Only 17.14% had reverse transcription-polymerase chain reaction positivity previously with 77.14% had positive COVID-19 serology. Most common features were fever (100%), edema (68.6%), gastrointestinal (71.4%), mucocuteneous (65.7%), cardiovascular (57.1%), and neurological symptoms (45.7%). Twenty (57.1%) children had shock at presentation. Decreased ejection fraction (<55%) was the most common echocardiographic feature (37.14%) followed by coronary dilatation (20%). Majority (77.14%) of the patients required intensive care with inotrope requirement in 62.86% cases. Forty percent patients were intubated with mean duration of 9.94 (±10.5) days. All patients received methylprednisolone and 76% were given intravenous immunoglobulin. Tocilizumab was used in three patients. Nine patients died (25.7%) with overall median pediatric intensive care unit stay of 13 (14) days. Of the parameters described, we have found shock, heart failure, neurological involvement at presentation, infancy, and laboratory parameters such as C-reactive protein, CPK, D-Dimer, and lactate dehydrogenase were the predictors of mortality.
