A rare case of metapneumovirus-induced rhabdomyolysis and multi-organ dysfunction in a 4-year-old child.

Human metapneumovirus (hMPV) is a common cause of acute respiratory tract infections in children. In immunocompetent individuals, the course of hMPV infection is usually benign and self-limiting. A developmentally normal, previously healthy 4-year-old girl presented with pneumonia and later developed rhabdomyolysis and multi-organ dysfunction syndrome (MODS) which was fatal. Extensive microbiological investigation for a possible viral aetiology was positive only for hMPV, thus making it the first reported case of hMPV infection-related rhabdomyolysis. Abbreviations: ARDS, acute respiratory distress syndrome; CK, creatinine kinase; hMPV, human metapneumovirus; MODS, multi-organ dysfunction syndrome; RSV, respiratory syncytial virus [ABSTRACT FROM AUTHOR]
