Abstract Background Autotaxin (ATX) is an emerging biomarker for liver fibrosis. Achievement of sustained virological response (SVR) by direct-acting antivirals (DAAs) results in hepatic fibrosis regression in chronic hepatitis C (CHC) patients. In this context, the clinical implications of ATX have not yet been well-defined. In this study, we aimed to assess the impact of achieving SVR with DAA therapy on serum ATX levels and whether these levels can reflect the regression of hepatic fibrosis in CHC patients. We evaluated serum ATX levels at baseline and 12 weeks post-DAA therapy in 48 CHC patients. We compared ATX with FIB4 score and AST-to-Platelet Ratio Index (APRI) as regards the detection of grade F3–4 fibrosis. Results Serum ATX levels were significantly declined in 47 patients after the achievement of SVR12 (p < 0.001). The diagnostic ability of ATX for the detection of grade F3–4 fibrosis was inferior to FIB4 and APRI scores at baseline and SVR12. Conclusion Achievement of SVR with DAA therapy causes a significant decline in serum autotaxin concentrations, suggesting early regression of hepatic fibrosis in CHC patients. However, its diagnostic capability for routine patient monitoring and follow-up is still under debate.

Abstracts Objectives: Direct acting antivirals (DAAs) have dramatically changed our approach towards management of chronic hepatitis C by yielding a high sustained virological response (SVR). Genotype-3 is the most common genotype found in Kashmir (Northern India) besides having an aggressive nature with increased risk of steatosis and hepatocellular carcinoma. We assessed the efficacy and safety of sofosbuvir plus valpatasvir based therapy in chronic hepatitis C genotype-3 infection in Kashmiri population. Aims and objectives: An observational, prospective, open label, hospital based study was carried over a period of two years which included 230 treatment naïve chronic hepatitis-C genotype-3 patients. Patients were divided in two groups. Group-A: Non-cirrhotics who received sofosbuvir (400 mg daily) with valpatasvir (100 mg) in fixed–dose combination for 12 weeks. Group B included CPT class A cirrhotics who received sofosbuvir (400mg daily) with valpatasvir (100 mg daily) and weight based ribavarin for 12 weeks. The primary end point was a sustained virologic response at 12 weeks after the end of therapy. Results and observations: We observed 98.57 % (138/140) SVR 12 in non-cirrhotics who received valpatasvir plus sofosbuvir treatment regimen. Cirrhotics who received Sofosbuvir plus valpatasvir with ribavirin observed SVR of 96.6 % (87/90). All patients tolerated the drug regimens well without any serious adverse effect. Conclusion: Once daily oral Sofosbuvir plus valpatasvir based fixed dose rerimen is highly efficient and safe in treatment of both cirrhotics and non-cirrhotic hepatitis C patients.

ABSTRACT BACKGROUND: In recent years the management of hepatitis C virus infection and the possibility of its eradication have been researched due to the importance that they represent in the health of the world population. Obtaining data that help to cope with this pathology improves the quality of life of those affected by it. The present study evaluated the effectiveness of direct-acting antiviral therapies provided by the Brazilian Ministry of Health in accordance to the Clinical Protocol and Therapeutic Guidelines of 2015. OBJECTIVE: To evaluate the epidemiological profile of patients with chronic hepatitis C and the rate of sustained virologic response using direct-acting antivirals of all individuals that attended the referral service for the treatment of chronic hepatitis C at the Hospital of the Federal University of Rio Grande. METHODS: This was an observational, retrospective/prospective study with all patients with chronic hepatitis C who had their treatments available from December 2015 to August 2017 according to the criteria of the Clinical Protocol and Therapeutic Guidelines of 2015. In the first phase, the clinical and demographic variables of all individuals enrolled in a treatment for hepatitis C were selected and collected from the Reference Service database. In the second phase, treatment data were collected. The outcome variable, sustained virologic response, was defined as an undetectable viral load on the blood test three months after the end of treatment. The descriptive and bivariate analyzes were performed with Pearson’s chi-square and Fisher’s Exact test, adopting a P value ≤0.05 in the SPSS 20 software. RESULTS: Of the 252 participants in the study, 228 (90.5%) had a sustained virologic response, 55.2% were male with an average age of 58.6 years (SD±9.1). Genotype 1 was the most prevalent, observed in 54.4% of the participants, and 87.4% of the patients had moderate/advanced hepatic fibrosis. After the statistical analysis, it was observed that the individuals with genotype 3 and moderate/advanced hepatic fibrosis had lower sustained virologic response rate (P=0.05 and P=0.04, respectively). CONCLUSION: It was observed that the use of direct-acting antivirals, in comparison to previous therapeutic regimens, increases the sustained virologic response, reaching all patients with mild fibrosis. This study provides information that helps in the hepatitis C treatment by showing that prescribing early treatment for patients without hepatic fibrosis and/or genotype 3 virus could increase therapeutic effectiveness.
