RESUMEN
BACKGROUND AND STUDY AIMS: Hepatitis C virus (HCV) impairs glucose homoestasis, thus influences its clinical picture and prognosis. This study aimed at evaluating Diabetes mellitus (DM) on Egyptian patients with chronic hepatitis C (CHC), and its impact on their virologic response when treated with directly acting antiviral (DAA) medications. PATIENTS AND METHODS: Adult patients with CHC were divided into 2 groups; Diabetic patients, and Non diabetic patients serving as control group. All patients were subjected to thorough clinical evaluation, basic biochemical laboratory tests including fasting blood glucose/glycosylated haemoglobin (HbA1C), and virologic assay. They were treated with various combined DAAs, and were monitored during, at and after end of treatment. RESULTS: Diabetic patients constituted 9.85 % of CHC, and had generally worse laboratory tests (significantly higher transaminases, platelet count, Fib4 and hepatic steatosis) than non diabetic patients, and a less sustained virologic response (SVR) (significantly in Sofosbuvir (SOF) + pegylated interferon (PegIFN) + ribavirin (RBV), SOF + RBV, SOF + daclatasvir (DAC)). Although DM did not play a significant influence on SVR, yet Fib4 and SOF + RBV + PEG-IFN were significant factors affecting SVR among diabetics, while female gender and viraemia were significant factors affecting SVR among non diabetics. Hepatic fibrosis and SOF/RBV significantly influenced SVR in both groups. CONCLUSIONS: Diabetic patients with CHC have worse liver biochemical profile, yet DM per se did not influence the virologic response to DAAs, however, some factors played roles in affecting SVR among them.
