Suramin treatment for chronic active hepatitis B—toxic and ineffective

Abstract

Suramin has recently been shown to inhibit the activity of the duck hepatitis B virus DNA polymerase (DHBV DNAp) in vitro. However, we found no demonstrable in vivo suppression of human hepatitis B virus DNA polymerase (HBV DNAp) activity in three male patients with severe chronic active hepatitis. Suramin treatment resulted in prolongation of the prothrombin time in all cases and a rise in bilirubin in two and it may have led to haemorrhage from oesophageal varices in one patient and to hepatic encephalopathy in another. Its use in chronic hepatitis is not recommended.
