Current level of evidence on causal association between Hepatitis C virus and type 2 diabetes: A review

Publication date: Available online 2 December 2016 Source:Journal of Advanced Research Author(s): Giacomo Gastaldi, Nicolas Goossens, Sophie Clément, Francesco Negro The association between hepatitis C virus (HCV) infection and type 2 diabetes (T2D) has been known for over 20 years. Cross-sectional and longitudinal studies have shown a higher prevalence and incidence, respectively, of T2D in patients with chronic HCV infection. HCV induces glucose metabolism alterations mostly interfering with the insulin signalling chain in hepatocytes, although extrahepatic mechanisms seem to contribute. Both IR and T2D accelerate the histological and clinical progression of chronic hepatitis C as well as the risk of extra-hepatic complications such as nephropathy, acute coronary events and ischemic stroke. Before the availability of direct-acting antivirals (DAAs), the therapeutic choice was limited to interferon (IFN)-based therapy, which reduced the incidence of the extra-hepatic manifestations but was burdened with several contraindications and poor tolerability. A better understanding of HCV-associated glucose metabolism derangements and their reversibility is expected with the use of DAAs. Graphical abstract

This study aimed to compare the therapeutic efficacy of metformin and other anti-hyperglycemic agents in hepatocellular carcinoma (HCC) patients with type 2 diabetes (T2D). MATERIALS: A systematic electronic search on keywords including HCC and different anti-hyperglycemic agents was performed through electronic databases including Medline and EMBASE. The primary outcome was the overall survival (OS). The secondary outcomes were the recurrence-free survival (RFS) and progression-free survival (PFS). RESULTS: Six retrospective cohort studies were included for analysis: Four studies with curative treatment for HCC (6...

Undergoing earlier menopause is a sign of a greater burden of age-related damage and dysfunction, so it should not be surprising to see that this correlates with a greater incidence of chronic disease in the years thereafter. People with a greater burden of cell and tissue damage tend to exhibit all of the manifestations of aging earlier than their less damaged peers. These variations in damage burden and consequences from individual to individual are near all the results of lifestyle choices, particularly smoking, weight, and exercise, and environmental factors such as exposure to chronic viral infection. Genetics plays o...
