Abstract:
Purpose - to analyze the literature data on possible variants of the course of pediatric multisystem inflammatory syndrome (PIMS-TS) in children; to describe our own experience in the diagnosis and treatment of some cases of PIMS-TS in children of different age groups; to present possible variants of clinical manifestations of the above disease; to draw attention to the need for early diagnosis and team care and treatment of such children. This novel clinical syndrome later identified as PIMS-TS temporally associated with SARS-CoV-2. In contrast with KD, PIMS-TS appears to occur in children at an older age with a predominance of gastrointestinal symptoms, hemodynamic instability, and myocardial dysfunction. However, the exact pathomechanism remains to be understood. Nevertheless, the post-viral immunological reaction is postulated to be the
underlying mechanistic underpinnings. The paper describes the clinical course of the disease in a 5-year-old boy who complained of abdominal pain and hyperthermia,
and the disease was masked by surgical pathology. The phenomena of intoxication syndrome, polyserositis, skin manifestations in the form of a polymorphic rash, hyperemia of the conjunctiva, swelling of the feet and hands increased in dynamics. The course of the disease in a 10-year-old girl who had symptoms of a viral infection is also described. However, upon going to the hospital, both children were diagnosed with a serious condition, they were hospitalized and given appropriate treatment. Therefore, the multifaceted nature of the PIMS-TS’ course underlines the need for early recognition and multispecialty care and management. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors
