[Indices of the interferon system in patients with viral myocarditis and dilated cardiomyopathy].

The authors presented some data on the investigation of the interferon system in patients with dilatation cardiomyopathy (DCM) and viral myocarditis (VM). Diagnosis was verified according to the WHO criteria. Altogether 10 DCM patients and 24 VM patients with a grave course were investigated. Antibodies to Coxsackie B virus and influenza were detected in the VM patients. A decrease in the alpha- and gamma-interferon activity was shown in all DCM patients. The VM patients with a grave course also demonstrated a decrease in the alpha- and especially gamma-interferon (immune) activity. Methods of immune correction in such patients were discussed.
