Abstract
BACKGROUND: Recently a severe form of COVID-19 infection has been described in a cluster of children presenting as multisystem inflammatory condition. One of the important spectrum of this condition is incomplete Kawasaki disease (KD). CASE REPORT: A 5-month-old male child presented with high-spiking fever for 5 days with skin rash, bilateral non-purulent conjunctivitis and irritability. His C-reactive protein was markedly elevated (215.4 mg/l). Echocardiography revealed dilated left main coronary artery (3.0 mm, Z score +4.30) and left anterior descending artery (2.37 mm, Z score +3.76). Concomitantly Reverse Transcription- Polymerase Chain Reaction for COVID-19 was positive on fifth day sample. He was diagnosed as incomplete KD with COVID-19 infection and treated with intravenous immunoglobulin (IVIG) (2 g/kg), oral aspirin and azithromycin. Patient improved after 48 h and was discharged on oral aspirin. CONCLUSION: Incomplete KD may co-exist with COVID-19 infection in infant. Early institution of IVIG may lead to better outcome.
