Clinically, the disease manifests itself most often 2\u20136 weeks after overcoming the infection. Young and middle-aged patients are especially affected. The clinical picture of the disease is very diverse. The dominant symptoms are mainly fever and myalgia, usually accompanied by various, especially extrapulmonary, manifestations. Cardiac damage (often in the form of cardiogenic shock) and significantly increased inflammatory parameters are often associated with MIS-A, while respiratory symptoms, including hypoxia, are less frequent. Due to the seriousness of the disease and the possibility of rapid progression, the basis of a successful treatment of the patient is early diagnosis, based mainly on anamnesis (overcoming the disease of COVID-19 in the recent past) and clinical symptoms, which often imitate other severe conditions such as, e.g., sepsis, septic shock, or toxic shock syndrome. Because of the danger of missing the treatment, it is necessary to initiate it immediately after the suspicion of MIS-A is expressed, without waiting for the results of microbiological and serological examinations. The cornerstone of pharmacological therapy is the administration of corticosteroids and intravenous immunoglobulins, to which the majority of patients clinically react. In this article, the authors describe the case report of a 21-year-old patient admitted to the Clinic of Infectology and Travel Medicine for febrility up to 40.5 \u00b0C, myalgia, arthralgia, headache, vomiting, and diarrhea three weeks after overcoming COVID-19. However, as part of the routine differential diagnosis of fevers (imaging and laboratory examinations), their cause was not clarified. Due to the overall worsening of the condition, the patient was transferred to the ICU with suspicion of developing MIS-A (he met all clinical and laboratory criteria). Given the above, reserve antibiotics, intravenous corticosteroids, and immunoglobulins were added to the treatment due to the risk of missing them, with a good clinical and laboratory effect. After stabilizing the condition and adjusting the laboratory parameters, the patient was transferred to a standard bed and sent home.<\/jats:p>","DOI":"10.3390\/diagnostics13050983","type":"journal-article","created":{"date-parts":[[2023,3,6]],"date-time":"2023-03-06T06:29:06Z","timestamp":1678084146000},"page":"983","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Multisystem Inflammatory Syndrome in Adults Associated with Recent Infection with COVID-19"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2682-4994","authenticated-orcid":false,"given":"Ondrej","family":"Zahornacky","sequence":"first","affiliation":[{"name":"Department of Infectology and Travel Medicine, Faculty of Medicine, Louis Pasteur University Hospital, Pavol Jozef \u0160afarik University, 04190 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2020-7573","authenticated-orcid":false,"given":"\u0160tefan","family":"Porub\u010din","sequence":"additional","affiliation":[{"name":"Department of Infectology and Travel Medicine, Faculty of Medicine, Louis Pasteur University Hospital, Pavol Jozef \u0160afarik University, 04190 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2282-1366","authenticated-orcid":false,"given":"Alena","family":"Rovnakova","sequence":"additional","affiliation":[{"name":"Department of Infectology and Travel Medicine, Faculty of Medicine, Louis Pasteur University Hospital, Pavol Jozef \u0160afarik University, 04190 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6518-9308","authenticated-orcid":false,"given":"Pavol","family":"Jarcuska","sequence":"additional","affiliation":[{"name":"Department of Infectology and Travel Medicine, Faculty of Medicine, Louis Pasteur University Hospital, Pavol Jozef \u0160afarik University, 04190 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1741","DOI":"10.1016\/S0140-6736(20)31129-6","article-title":"Kawasaki-like disease: Emerging complication during the COVID-19 pandemic","volume":"395","author":"Viner","year":"2020","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"P\u00e9rez, A., Torregrosa, I., D\u2019Marco, L., Juan, I., Terradez, L., Sol\u00eds, M.\u00c1., Moncho, F., Carda-Batalla, C., Forner, M.J., and Gorriz, J.L.
