Two cases of acute myositis associated with influenza A virus infection in the elderly

J Nippon Med Sch. 2000 Apr;67(2):126-9. doi: 10.1272/jnms.67.126.

Abstract

During the influenza epidemic of 1998-1999, we observed two elderly patients with influenza-like symptoms who had evidence of acute myositis with elevated serum enzymes. Influenza A infection was confirmed serologically in either case. The present cases suggest that it is important to distinguish influenzal myositis from other forms of myopathy in the elderly patients.
