Introduction: Kawasaki disease (KD) is one of the most common vasculitis of childhood. It contributes significantly to acquired heart disease in children and results in coronary artery abnormalities including aneurysm in 25% of untreated children. This study aims to retrospectively assess the clinical course, laboratory results, and presenting symptoms of patients with complete and incomplete KD treated at tertiary care hospital in Kathmandu.Method: This retrospective study was conducted in the Department of Pediatrics. Data from January 2020 to December 2020 were retrieved from medical records department of the hospital and analyzed using Microsoft excel.Result: The total number of cases evaluated in our study was 9. The median age at the time of the diagnosis of KD was 24 months (median age for incomplete KD-21 months, complete KD-37 months). Male to female ratio was 1.2:1. The peak season of KD occurrence was Spring (March – May). Mean duration of stay in the hospital was 7 days. All children presented with fever, with an mean fever duration of 7 days at the time of presentation. Fever was present in every case. The most common principal symptom was a polymorphous skin rash, observed in 88% of the cases. Elevated CRP levels (≥3 mg/dl) were noted in all 9 cases. Cardiovascular complications were present in 88% of the patients, with coronary artery aneurysm (CAA) detected in 11%, coronary artery dilation in 22%, and mild pericardial effusion documented in 66% of the cases. Eight patients (88%) received IVIG, all 9 patients (100%) received aspirin, and 2 patients received steroids. There were no fatalities.Conclusion: KD is a common vasculitis in children which do not have significant sex predilection in oppose to most of the studies. Majority of cases occurred in spring season. The most common symptom was polymorphous rash. A high level of suspicion for diagnosing KD is essential, and early treatment is crucial to prevent complications and reduce the future economic burden on families and the nation.
