Hepatitis B virus with primary resistance to adefovir.
The reverse-transcriptase inhibitor lamivudine (Zeffix, GlaxoSmithKline) is often used to treat chronic infection with hepatitis B virus (HBV) until resistance develops. Treatment may then be switched to the reverse-transcriptase inhibitor adefovir (Hepsera, Gilead), which has a lower frequency of resistance. Here, we describe three cases of primary adefovir resistance that were sensitive to te...
متن کاملHEPATITIS B VIRUS INFECTION IN AN ANTI-HBC NEGATIVE PATIENT: A CASE REPORT
ABSTRACT One of the best reliable markers of hepatitis B virus infection is antibodies to the core antigen (Anti-HBc). A first-time blood donor with HBsAg positivity was identified as an HBV carrier that was anti-HBc negative. The patient was followed for 24 months in order to investigate the evolution of his HBV serological profiles and HBVDNA (PCR). In the follow-up for 24 months, HBsAg, HBe...
متن کاملComplex dynamics of hepatitis B virus resistance to adefovir.
UNLABELLED In patients with hepatitis B e antigen-negative chronic hepatitis B, adefovir dipivoxil administration selects variants bearing reverse transcriptase rtN236T and/or rtA181V/T substitutions in 29% of cases after 5 years. The aim of this study was to characterize the dynamics of adefovir-resistant variant populations during adefovir monotherapy in order to better understand the molecul...
متن کاملPathological femoral fractures due to osteomalacia associated with adefovir dipivoxil treatment for hepatitis B: a case report
UNLABELLED We present a case of a 62-year-old man who underwent total hip arthroplasty for treatment of pathologic femoral neck fracture associated with adefovir dipivoxil-induced osteomalacia. He had a 13-month history of bone pain involving his shoulders, hips, and knee. He received adefovir dipivoxil for treatment of lamivudine-resistant hepatitis B virus infection for 5 years before the occ...
متن کاملPseudoporphyria in association with Hepatitis C virus infection: A case report
Pseudoporphyria is an uncommon bullous disease with similar clinical and histopathological findings to porphyria cutanea tarda, in the absence of detectable porphyrin elevation. We present a 34-year-old man with clinical and histological findings compatible with porphyria cutanea tarda, whose his urinary uroporphyrin was negative and we concluded that he was a case of pseudoporphyria. Concomita...
