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.

Difficult-to-treat populations with chronic hepatitis C (CHC), in the era of interferon treatment, included patients with liver cirrhosis, kidney impairment, treatment-experienced individuals, and those coinfected with the human immunodeficiency virus. The current study aimed to determine whether, in the era of direct-acting antivirals (DAA), there are still patients that are difficult-to-treat. The study included all consecutive patients chronically infected with hepatitis C virus (HCV) who started interferon-free therapy between July 2015 and December 2020 in the Department of Infectious Diseases in Kielce. The analyzed real-world population consisted of 963 patients, and most of them were infected with genotype 1 (87.6%) with the predominance of subtype 1b and were treatment-naïve (78.8%). Liver cirrhosis was determined in 207 individuals (21.5%), of whom 82.6% were compensated. The overall sustained virologic response, after exclusion of non-virologic failures, was achieved in 98.4%. The univariable analysis demonstrated the significantly lower response rates in males, patients with liver cirrhosis, decompensation of hepatic function at baseline, documented esophageal varices, concomitant diabetes, body mass index ≥25, and previous ineffective antiviral treatment. Despite an overall very high effectiveness, some unfavorable factors, including male gender, genotype 3 infection, liver cirrhosis, and treatment experience, significantly reduce the chances for a virologic response were identified.

Abstract Background Clearance of hepatitis C virus (HCV) results in rapid changes in metabolic parameters early in direct-acting antiviral (DAA) therapy. Long-term changes after sustained virologic response (SVR) remain unknown. Methods We investigated longitudinal changes in metabolic and inflammatory outcomes in chronic hepatitis C (CHC) patients: low-density lipoprotein (LDL), high-density lipoprotein, triglycerides, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) using a general linear model for repeated measurements at 5 clinical time points and by human immunodeficiency virus (HIV) coinfection and IFNL4 genotype. Results The mean LDL increased markedly during DAA therapy (pre-DAA, 86.6 to DAA, 107.4 mg/dL; P < .0001), but then it decreased to 97.7 mg/dL by post-SVR year 1 (P < .001 compared with DAA; P = .0013 compared with SVR). In patients who carry the IFNL4-ΔG allele, mean LDL increased during treatment, then decreased at post-SVR year 1; however, in patients with TT/TT, genotype did not change during and after DAA treatment. The mean ALT and AST normalized rapidly between pre-DAA and DAA, whereas only mean ALT continued to decrease until post-SVR. Metabolic and inflammatory outcomes were similar by HIV-coinfection status. Conclusions Changes in LDL among CHC patients who achieved SVR differed by IFNL4 genotype, which implicates the interferon-λ4 protein in metabolic changes observed in HCV-infected patients.
