Hepatitis B virus reactivation during combined therapy with deferiprone and desferioxamine in a hepatitis B surface antigen thalassemic carrier.

In this report we firstly describe a case of reactivation of hepatitis B virus (HBV) replication occurred in a patient affected by Thalassemia major which underwent a combined chelation therapy with desferioxamine (DFO) and deferiprone (DFP). Clinical symptom and increase in alanine aminotransferase (ALT) level were detected when the prescription of DFO (30 mg/kg) was increased from 3 to 5 days/week; a raise in HBV-DNA levels of greater than or equal to tenfold compared with baseline was thereafter detected. Diagnosis was troublesome because increasing ALT levels, first suggested toxicity to DFP administration.
