title: HBV-related liver disease in renal insufficiency: successful antiviral therapy with entecavir.
abstract: Hepatitis B virus (HBV) infection persists among patients with renal insufficiency in the industrialized world. A variety of therapeutic options are now available for the treatment of chronic hepatitis B infection, including potent new nucleos(t)ide analogs, along with standard and pegylated interferon. We report on a patient with aggressive hepatitis B and renal insufficiency who was successfully treated with nucleoside analogs (mostly entecavir monotherapy) for two years. He received intense immunosuppression for severe myopathy of lower limbs, probably related to vasculitis. HBV DNA (at the beginning, > 1 x 10(8) IU/mL) was no longer detectable in serum after a few months of antiviral therapy, while HBeAg and HBsAg seroconversion occurred with ALT normalization. Clinical signs of vasculitis disappeared. Five months after discontinuation of entecavir therapy, he remained HBsAg negative with detectable anti-HBs antibody in serum. We conclude that nucleos(t)ide analogs can offer excellent response in selected patients with renal insufficiency and hepatitis B-related liver disease. Prospective, controlled clinical trials are needed to confirm these encouraging results.
