385. Kawasaki’s Disease and Sars-Cov-2: an Unexpected Pediatric Global Crisis?

Abstract

Background: Infection by SARS-CoV-2 can lead to dyspnea, edema, deposition of intra alveolar fibrin, thrombosis and hemorrhages. During the COVID-19. outbreak, several questions were raised about the risks for the pediatric population. Pediatric patients appeared to be relatively safe, with only minor symptoms and a quick recovery. However, there have been reports of a relationship between COVID 19 and a Kawasaki-like inflammatory disease in this population. Kawasaki's disease (KD) is a rheumatological vasculitis prevalent in childhood characterized mainly by diffuse inflammation of the arteries associated with skin rash, changes in the mucosa and its main complication is coronary aneurysms. Method(s): A systematic literature review was performed in the PubMED database using the keywords "Kawasaki disease", "COVID-19" and "Pediatrics". The selected filters were "Case reports", "Multicenter study", "Clinical Study", "Observational study", "Human" and "English". A total of 18 articles were seleted. Result(s): There seems to be a convergence between the literature published so far, pointing to a greater propensity for pediatric patients infected with Sars-Cov-2 to develop KD. The number of patients with KD symptoms seen at a specific center increased from 2 to 17 in 11 days (MOREIRA, 2020). In a sample space of 21 patients diagnosed with KD, 91% had previous contact with SARS-CoV-2 (TOUBIANA, 2020) whereas other studies point to a 30-fold increase in the prevalence of KD since the beginning of 2020 (VERDONI, 2020). There is already an established relationship between DK and HCoV-NH, describing that 4.5% of patients with this infection develop KD. Therefore, it was suggested that infection with another Coronavirus strain could have a similar relationship. Conclusion(s): Despite the relationship described between pediatric patients infected with COVID-19 being more likely to develop KD, further studies are needed to prove a statistical relationship between both condition.
