[Hyperinflammatory immune response syndrome PIMS-TS].

Introduction: PIMS-TS is a rare hyperinflammatory immune response syndrome, usually occurring two to six weeks after SARS-CoV-2 infection, which mainly affects schoolchildren and is often associated with the need for intensive care (2). The most common clinical signs are high fever, gastrointestinal symptoms such as abdominal pain, vomiting and diarrhea, cardiovascular dysfunction (impaired LVEF, hypotension, shock) and neurological symptoms such as headache and encephalopathy (1, 2, 4). The definition criteria include various clinical and laboratory parameters, which vary slightly depending on the authors (4, 6, 7). With intensive care treatment with circulatory support and administration of methylprednisolone, mortality and long-term consequences remain low.
