An increase in genotypes 1a and 4a suggest migration of people, possibly from Balochistan and the northern war-zone area. Government should focus on public education regarding infection routes.

BackgroundHepatitis C can lead to liver fibrosis and cirrhosis. We compared readily available non-invasive fibrosis indexes for the fibrosis progression discrimination to find a better combination of existing non-invasive markers.MethodsWe studied 157 HCV infected patients who underwent liver biopsy. In order to differentiate HCV fibrosis progression, readily available AAR, APRI, FI and FIB-4 serum indexes were tested in the patients. We derived a new fibrosis-cirrhosis index (FCI) comprised of ALP, bilirubin, serum albumin and platelet count. FCI = [(ALP × Bilirubin) / (Albumin × Platelet count)].ResultsAlready established serum indexes AAR, APRI, FI and FIB-4 were able to stage liver fibrosis with correlation coefficient indexes 0.130, 0.444, 0.578 and 0.494, respectively. Our new fibrosis cirrhosis index FCI significantly correlated with the histological fibrosis stages F0-F1, F2-F3 and F4 (r = 0.818, p < 0.05) with AUROCs 0.932 and 0.996, respectively. The sensitivity and PPV of FCI at a cutoff value < 0.130 for predicting fibrosis stage F0-F1 was 81% and 82%, respectively with AUROC 0.932. Corresponding value of FCI at a cutoff value ≥1.25 for the prediction of cirrhosis was 86% and 100%.ConclusionsThe fibrosis-cirrhosis index (FCI) accurately predicted fibrosis stages in HCV infected patients and seems more efficient than frequently used serum indexes.

Chronic hepatitis C virus infection and associated liver diseases represent a major health care burden all over the world. The current standard of care, i.e. peginterferon-alfa (PEG-IFNα) plus ribavirin (RBV) are associated with frequent and sometimes serious adverse effects and contraindications, which further limit their therapeutic efficacy. The approval of first and second generation HCV protease inhibitors represents a major breakthrough in the development of novel direct acting antivirals (DAAs) against different HCV genotypes and establishes a new standard of care for chronically infected HCV genotypes 1 patients. Similarly, next generation protease inhibitors and HCV RNA polymerase inhibitors have shown better pharmacokinetics and pharmacodynamics in terms of broader HCV genotypes coverage, better safety profile, fewer drug interactions and possible once daily administration than first generation direct acting antivirals. The testing of adenovirus-based vector vaccines, which escalates the innate and acquired immune responses against the most conserved regions of the HCV genome in chimpanzees and humans, may be a promising therapeutic approach against HCV infection in coming future. This review article presents up-to-date knowledge and recent developments in HCV therapeutics, insights the shortcomings of current HCV therapies and key lessons from the therapeutic potential of improved anti-HCV treatment strategies.
