Influenza B infection can present with severe myocarditis and myositis requiring advanced mechanical circulatory and renal support.
Successful multimodal support feasible in refractory pediatric influenza B myocarditis; leaves optimal protocols and broader applicability open.
OBJECTIVE: To report an influenza B infection with associated myocarditis and severe skeletal myositis. DESIGN: Case report. SETTING: Cardiac intensive care unit in a university-affiliated children's hospital. PATIENT: A 4-yr-old girl. RESULTS: The patient was successfully supported with extracorporeal membrane oxygenation for profound myocardial dysfunction and a combination of plasmapheresis and continuous venovenous hemodialysis for rhabdomyolysis and acute renal failure. CONCLUSIONS: This case provides a reminder that patients presenting with viral illness or myoglobinuria accompanied by renal failure, with or without associated myocarditis, may be demonstrating symptoms of influenza B.

Tabbutt et al. (2004) conducted a case report in Influenza B infection with associated myocarditis and severe skeletal myositis (n=1). Extracorporeal membrane oxygenation, plasmapheresis, and continuous venovenous hemodialysis was evaluated. A 4-year-old girl with severe influenza B myocarditis and myositis was successfully supported with extracorporeal membrane oxygenation, plasmapheresis, and continuous venovenous hemodialysis.
