Saffold virus infection associated with human myocarditis

Publikation: Bidrag til tidsskriftLetterForskningfagfællebedømt

BACKGROUND: Saffold virus was described in 2007 as one of the first human viruses within the genus cardioviruses. Cardioviruses may cause severe infections of the myocardium in animals, and several studies have associated saffold virus with human disease. As a result, saffold virus has been isolated from different anatomical compartments, including the myocardium, but, until now, it has not been possible to demonstrate the accompanying histopathological signs of inflammation.

OBJECTIVES: The aim of the study was to examine if saffold virus is capable of causing invasive infection in the human myocardium.

STUDY DESIGN: Using real-time PCR, we retrospectively examined formalin-fixed paraffin embedded cardiac tissue specimens from 150 deceased individuals diagnosed with myocarditis at autopsy. The results were compared with histological findings.

RESULTS AND CONCLUSIONS: Saffold virus was detected in the myocardium, lung tissue and blood of one child and was accompanied by histopathological inflammation in the heart and lungs, which was supportive of a viral infection. These findings suggest that cardioviruses may be associated with myocarditis in humans.
