Popis: Introduction Differential diagnosis of the systemic juvenile idiopathic arthritis (sJIA) is often complicated, because of the variability in clinical presentation and the absence of specific signs. Material and Methods The PubMed/Medline and Scopus databases from the years 2013–2022 were analysed for full articles in English and the following key words were used: “juvenile idiopathic arthritis” and “MIS-C”; “juve-nile idiopathic arthritis” and “Kawasaki disease”. As an example of the problem the case description of a 3-year-old patient is presented. Results In the first step 167 publications were identified; however, after exclusion of duplicated articles and those not relevant to the topic, only 13 were included in the analysis. We analysed studies that de-scribe overlapping clinical features of sJIA and Kawasaki disease (KD) or multisystem inflammatory syndrome in children (MIS-C). The main issues we discussed were the search for the specific fea-tures that would distinguish one disease from another. Fever refractory to intravenous immuno-globulin treatment was the most frequent indicator among the features of clinical courses. Among other clinical signs prolonged, recurrent fever, rash, an incomplete KD phenotype, Caucasian race, splenomegaly, and complicated macrophage activation syndrome also supported sJIA diagnosis. Among laboratory tests, high ferritin and serum interleukin-18 levels were found to be the most useful in differentiation. The present case demonstrates that prolonged, unexplained, recurrent fe-ver with a specific pattern should be the reason to suspect sJIA. Conclusions Overlapping features of sJIA and SARS-CoV-2-related MIS-C complicates diagnosis in the era of the COVID-19 pandemic. Our case presentation adds symptoms of prolonged, spiking, unexplained, re-current fever with a specific pattern for supporting systemic juvenile idiopathic arthritis diagnosis.
