[COVID-19-associated hyperinflammatory state in a 15-year-old female patient].

Paediatric Multisystem Inflammatory Syndrome Temporally Related to SARS-CoV-2 (PIMS-TS) is a rare novel clinical entity observed in children and adolescents with evidence of a recent COVID-19 infection, and is characterized by a marked hyperinflammatory state with involvement of multiple organ systems.We report a case of a previously healthy 15-year-old female patient, who was admitted to paediatric intensive care with cardiac failure and was subsequently shown to have positive COVID-19 serology. The presenting symptoms were fever, cough, chest pain and gastro-intestinal symptoms. She was supported with milrinone and a low dose of vasopressors. Her hyperinflammatory state was treated with intravenous immunoglobulins, high dose aspirin and high-dose methylprednisolone. PIMS-TS is a rare, potentially life threatening novel clinical entity in children and adolescents with evidence of a COVID-19 infection. Clinicians need to be aware of the possibility of this new disease, to ensure prompt recognition and treatment.
