1Assessing cardiovascular risk in hepatitis C: An unmet need显示文摘Chronic hepatitis C virus(HCV) is associated with significant morbidity and mortality, as a result of the progression towards cirrhosis and hepatocellular carcinoma. Additionally, HCV seems to be an independent risk factor for cardiovascular diseases(CVD) due to its association with insulin resistance, diabetes and steatosis. HCV infection represents an initial step in the chronic inflammatory cascade, showing a direct rolein altering glucose metabolism. After achieving sustained virological response, the incidence of insulin resistance and diabetes dramatically decrease. HCV core protein plays an essential role in promoting insulin resistance and oxidative stress. On the other hand, atherosclerosis is a common disease in which the artery wall thickens due to accumulation of fatty deposits. The main step in the formation of atherosclerotic plaques is the oxidation of low density lipoprotein particles, together with the increased production of proinflammatory markers [tumor necrosis factor-α, interleukin(IL)-6, IL-18 or C-reactive protein]. The advent of new direct acting antiviral therapy has dramatically increased the sustained virological response rates of hepatitis C infection. In this scenario, the cardiovascular risk has emerged and represents a major concern after the eradication of the virus. Consequently, the number of studies evaluating this association is growing. Data derived from these studies have demonstrated the strong link between HCV infection and the atherogenic process, showing a higher risk of coronary heart disease, carotid atherosclerosis, peripheral artery disease and, ultimately, CVD-related mortality.Javier Ampuero Manuel Romero-Gómez 2015World Journal of Hepatology2015,7,19:1
2Hepatitis C virus genotype 3: Meta-analysis on sustained virologic response rates with currently available treatment options显示文摘AIM: To address the therapeutic efficacy of various treatment regimens in genotype 3 selecting randomized clinical trials and prospective National Cohort Studies.METHODS:(1) PEG-INF-based therapy including sofosbuvir(SOF) + RBV for 12 wk vs SOF + RBV 24 wk;(2) SOF + RBV therapy 12 wk/16 wk vs 24 wk; and(3) the role of RBV in SOF + daclatasvir(DCV) and SOF + ledipasvir(LDV) combinations. This metaanalysis provides robust information with the intention of addressing treatment strategy for hepatitis C virus genotype 3.RESULTS: A combination treatment including SOF + RBV + PEG-IFN for 12 wk notes better SVR than with only SOF + RBV for 12 wk, although its association with more frequent adverse effects may be a limiting factor. Longer duration therapy with SOF + RBV(24 wk) has achieved higher SVR rates than shorter durations(12 or 16 wk). SOF + LDV are not an ideal treatment for genotype 3. CONCLUSION: Lastly, SOF + DCV combination is probably the best oral therapy option and the addition of RBV does not appear to be needed to increase SVR rates substantially.Javier Ampuero K Rajender Reddy Manuel Romero-Gomez 2016World Journal of Gastroenterology2016,22,22:1
