<p>Low-dose adefovir dipivoxil–induced hypophosphatemia osteomalacia in five chronic hepatitis B virus–infected patients. Is low-dose adefovir dipivoxil–induced nephrotoxicity completely reversible?</p>

Adefovir dipivoxil (ADV) is one of the most important nucleostide analogues currently in use for the treatment of chronic hepatitis B virus (HBV) infection. Low-dose ADV-induced nephrotoxicity in most cases was reported to be reversible after the discontinuation of ADV or by decreasing the dose of ADV. In our study, we have 5 documented cases of low-dose ADV-induced hypophosphatemia osteomalacia with or without Fanconi syndrome which were...
