BACKGROUND The optimization of combination therapy with ribavirin (RBV) and pegylated interferon alpha has substantially improved sustained virologic response (SVR) rates and lowered virologic relapse rates in patients infected with hepatitis C virus (HCV). In this study, we performed an analysis of the relationship between the end-of-treatment plasma RBV(More)
BACKGROUND/AIM Sorafenib is the medical reference for treatment of hepatocellular carcinoma (HCC). Multiple forms of cytotoxicity are induced by sorafenib in HCC cells in vitro but it is unclear what extent of apoptosis and necrosis is induced in HCC patients receiving sorafenib. PATIENTS AND METHODS The M30 and M65 biomarkers, which reflect the release(More)
N-methyl-2-pyridone-5-carboxamide (2PY, a major metabolite of nicotinamide, NAM) was recently identified as a uremic toxin. Recent interventional trials using NAM to treat high levels of phosphorus in end-stage renal disease have highlighted new potential uremic toxicities of 2PY. In the context of uremia, the accumulation of 2PY could be harmful-perhaps by(More)
Anemia is a well-known RBV-related event in HCV therapy which is exacerbated by the addition of telaprevir and boceprevir. This retrospective study evaluated and compared ribavirin exposure and parameters able to influence hemoglobin decrease in a large population of patients treated with dual or triple therapy. Patients on triple therapy had higher(More)
Despite the availability of new oral anticoagulants, vitamin K antagonists (VKA, such as fluindione, acenocoumarol or warfarin) remain currently the goal standard medicines for oral prevention or treatment of thromboembolic disorders. They inhibit the cycle of the vitamin K and its participation in the enzymatic gamma-carboxylation of many proteins. The VKA(More)
Ribavirin-induced anemia is the major side effect observed during HCV therapy. In an in vitro study, we recently discovered that DHEA can strongly inhibit this adverse event. We also evaluated a possible link between pre-treatment serum DHEA and hemoglobin during HCV therapy. Among the 108 patients of our cohort serum baseline DHEA levels were associated(More)
BACKGROUND/AIM Organ transplant patients treated with the immunosuppressive drug cyclosporine A often present malignant kidney tumors. Cyclosporine A can promote oncogenesis in a cell-intrinsic manner by increasing the production of vascular endothelial growth factor (VEGF). MATERIALS AND METHODS We explored the impact of cyclosporine A and the role of(More)
