Abstract
BackgroundHepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM) are two major public health problems associated with increasing complications and mortality rates worldwide. The objective of this study is to evaluate the prevalence of hepatitis C virus (HCV) infection in diabetic patients and to investigate the influence of several epidemiological and clinical factors on HCV infection.MethodA total number of one hundred and eighty diabetic patients were recruited for this study. Consented subjects made up of 71(39.4%) males and 109(60.56%) females were recruited for the study. While one-Hundred (100) Non-Diabetics (Controls) were also recruited for the study. Structured questionnaires were administered to the consented participants to obtain relevant data. Sera samples were assayed for antibodies to HCV using an enzyme linked immunosorbent assay [Inteco Diagnostic Limited]. ELISA technique.ResultOverall prevalence of HCV infection among diabetes patients assayed was 13.3% out of which 8(11.3%) was obtained from the male subjects compared to 16 (14.7%) seropositivity recorded among the females (P=0.511; P>0.05). Considering age distribution, Subjects aged 41-50years recorded, 9 (22.5%) positivity (P=0.238; P>0.05).Considering educational status of subjects screened, 22 (14.9%) positivity was rescored among subjects who have attained tertiary status of education.(P=0.574;P>0.05).Risk factors considered showed that, 7 (18.9%) seropositive subject were alcoholic consumers(P value=0.2621;P>0.05) while 5 (8.9%) recorded history of sharing sharp objects P=0.2427;P>0.05).ConclusionOur study shows a slightly higher prevalence of hepatitis C infection in type 2 diabetics. This call for urgent routine screening exercise among diabetic patients for HCV infection. This study also emphasizes the need for public enlightenment on the association between HCV infection and T2DM, to avert possible complications among diabetic patients.

Abstract
Aim We analyzed the impact of hepatitis C virus eradication by direct-acting antiviral (DAA) therapy on the risk of development of hepatocellular carcinoma (HCC), prognosis, and portal hypertension in patients with liver cirrhosis. Methods The rate of HCC development and overall survival after achievement of sustained virological response (SVR) in 173 DAA-treated compensated cirrhosis patients without HCC history were retrospectively compared with that of 125 cirrhosis patients who achieved SVR by interferon (IFN)-based therapy or that of 85 cirrhosis patients who failed to respond to anti-HCV therapy. Changes in esophagogastric varices (EGV) and incidence of portosystemic encephalopathy were analyzed in 87 consecutive cirrhosis patients. Results The cumulative HCC development rates at 1, 3, and 5 years were 2%, 7%, and 7% for the DAA-SVR group, significantly lower than the 3%, 7%, and 18% for the non-SVR group (log-rank,P < 0.001). The cumulative overall survival rates were also significantly improved in the DAA-SVR group compared to the non-SVR group (log-rank,P < 0.001). These rates were similar between DAA-SVR and IFN-SVR groups (P = 0.121 and 0.261, respectively). Esophagogastric varices were aggravated, and portosystemic encephalopathy occurred in a subset of cirrhosis patients who achieved SVR by DAA therapy. These events were more frequent in patients with large feeding vessels for EGV and portosystemic shunts at the time of SVR. Conclusion Achievement of SVR by DAA therapy reduces the risk of HCC development and prolongs survival, similar to theresults achieved with IFN-based therapy, but portal hypertension is not immediately improved in compensated liver cirrhosis patients.
