Staphylococcus aureus endocarditis and pyomyositis: Rare complications of rotavirus gastroenteritis.

Rotavirus may cause life-threatening complications in untreated patients during the course of gastroenteritis. Electrolyte imbalance, bacteremia and sepsis are the most common complications of rotavirus gastroenteritis (RG). It is believed that translocation of intestinal microorganisms as a result of intestinal epithelium dysfunction is the underlying mechanism of bacteremia in RG. Although Gram-negative bacteremia has been noted as a complication in RG, Staphylococcus aureus bacteremia and endocarditis have not been reported previously. A 22-month-old boy was admitted with complaints of fever, diarrhea and dehydration. He was diagnosed with RG complicated with S. aureus bacteremia, pyomyositis and endocarditis. We call attention to these complications in patients with prolonged or late-onset fever during RG as rare complications of the disease.
