Postcovid Multisystemic Inflammatory Syndrome in a Child with Acute Obstructive Pneumonia

Abstract Childhood inflammatory multisystemic syndrome (CIS-C) is a serious late complication of SARS-CoV-2 infection that can develop in some children and young adults. Criteria for defining SIM-C in children include fever≥ 38.0°C, laboratory findings suggestive of an inflammatory process increased - C-reactive protein, D-dimer, VSH, ferritin, LDH, IL-6, neutrophils, procalcitonin, venous blood gas and lactate levels, brain natriuretic peptide; decreased - lymphocytes, platelets, serum albumin, serum sodium, manifestations of multisystem involvement with >2 organs/systems (cardiac, renal, respiratory, haematological, gastrointestinal, dermatological or neurological), absence of plausible alternative diagnosis, recent or currently positive COVID-19 infection, or contact with confirmed COVID-19 case within 4 weeks prior to onset of symptoms. The authors present the case of a 3-year-old girl aged 3 years and 5 months, admitted to the Pediatric Clinic of the Hospital Clinic Judetean de Urgenta Constanta in January 2022, for fever (39.5°C), microerythematous rash, semi-productive cough. and dyspnea. Investigations detected anticovid antibodies present, with no SARS cov2 infection diagnosed in the personal pathological history.
