ABSTRACT Background The effectiveness of antiviral therapy with pegylated interferon and ribavirin for chronic hepatitis C is far from ideal and presents several adverse events. Among such events, there is the depressive episode that can even lead to treatment discontinuity Objective Analyze the incidence of depressive episodes in patients with chronic hepatitis C treated with pegylated interferon (IFN-PEG) and ribavirin, as well as the possible factors associated with its occurrence and its impact on patients' sustained virological response. Methods People with chronic hepatitis C undergoing antiviral therapy were interviewed at the baseline, at the 4th, 12th, 24th and 48th treatment weeks and 4 weeks after the end of it, using the HADS scale for tracking the depressive episode. Patients with HADS ≥9 were subjected to Beck Depression Inventory (BDI-II) to grade the episode. Clinical, sociodemographic, laboratorial and histological variables were obtained to identify factors related to the onset of depression. The sustained virological response rate (negative HCV-RNA 6 months after end of therapy) was compared among patients with and without depressive symptoms. Results The study comprised 32 patients, most men (59%) with mean age of 54±11.13 years old. Genotype non-1 was prevalent (56%) and 81% of the patients were non-cirrhotic. The depressive episode was diagnosed in 25% of the patients and the peak incidence was found in the 12th treatment week. The depressive episode was moderate in 87% of the patients and only one patient abandoned the treatment. None of the analyzed factors was associated with depressive episode onset. A trend was observed in female patients ( P=0.08). The sustained virological response rate was of 75% and 67% in patients with and without depressive episode, respectively (P =0.66). Conclusion The incidence of depressive episodes in patients with chronic hepatitis C undergoing antiviral therapy was of 25% and the 12th treatment week was the most critical one. The presence of depressive episode did not affect the sustained virological response rate.

Introduction: In chronic hepatitis C-virus infection the possible role of gene variants encoding cytokines has become the focus of interest. Aim: The aim of the study was to investigate the effect of IL28B polymorphisms on the outcome of chronic hepatitis C-virus genotype 1 infection in the Hungarian population. In addition, the association between IL28B genotypes and the Th1/Th2 cytokine production of activated peripheral blood monocytes and lymphocytes was evaluated. Method: Total of 748 chronic hepatitis C-virus genotype 1 positive patients (365 males and 383 females, aged between 18 and 82 years; mean age, 54±10 years) were enrolled, of which 420 patients were treated with pegylated interferon plus ribavirin for 24–72 weeks. Of the 420 patients, 195 patients (46.4%) achieved sustained virological response. The IL28B rs12979860 polymorphism was determined using Custom Taqman SNP Genotyping Assays (Applied Biosystems, Life Technologies, Foster, CA, USA). For cytokine studies, tumour necrosis factor-α, interleukin-2, interferon-γ, interleukin-2 and interleukin-4 production by LPS-stimulated monocytes and PMA-ionomycine activated lymphocytes were measured from the supernatant of the cells obtained from 40 hepatitis C-virus infected patients, using FACS-CBA Becton Dickinson test. The cytokine levels were compared in patients with different (CC, CT, TT) IL28B genotypes. Results: The IL28B rs12979860 CC genotype occurred in lower frequency in hepatitis C-virus infected patients than in healthy controls (26.1% vs 51.4%, OR 0.333, p<0.001). Patients carried the T allele with higher frequency than controls (73.9%, vs 48.6%, OR 3.003, p<0.001). Pegylated interferon plus ribavirin treated patients with the IL28B CC genotype achieved higher sustained virological response rate than those with the CT genotype (58.6% vs 40.8%, OR 2.057, p = 0.002), and those who carried the T allele (41.8%, OR1.976, p = 0.002). LPS-induced TLR-4 activation of monocytes resulted in higher tumour necrosis factor-α production in patients with the IL28B CC genotype compared to non-CC individuals (p<0.01). Similarly, increased tumour necrosis factor-α, interleukin-2 and interferon-γ production by lymphocytes was found in the IL28B CC carriers (p<0.01) Conclusions: The IL28B CC genotype exerts protective effect against chronic hepatitis C-virus infection and may be a pretreatment predictor of sustained virological response during interferon-based antiviral therapy. The IL28B CC polymorphism is associated with increased Th1 cytokine production of activated peripheral blood monocytes and lymphocytes, which may play a role in interferon-induced rapid immune control and sustained virological response of pegylated interferon plus ribavirin treated patients.

BackgroundTreatment of hepatitis C virus infection in post-transplantation patients is a challenge due to poor tolerance and low success rates.ObjectiveTo determine the response rate to pegylated interferon and ribavirin in post-liver transplant patients with hepatitis C recurrence.MethodsBetween 18 May 2002 and 18 December 2011, 601 patients underwent liver transplantation at our service (Hospital Universitário Walter Cantídio, University of Ceará), 176 (29.2%) of whom were hepatitis C virus positive. Forty received antiviral therapy and were included in this cohort study. Twenty-eight (70%) completed the treatment protocol, which consisted of pegylated interferon and ribavirin for 48 weeks.ResultsThe sustained virological response rate was 55% according to intention-to-treat analysis. Recipient age and exposure to antiviral drugs prior to liver transplantation were associated with sustained virological response in the multivariate analysis. Patients were followed for 57 months on the average. Survival at 1 and 5 years was 100% in responders, versus 100% and 78%, respectively, in non-responders.ConclusionSustained virological response rates were satisfactory in our series of liver transplantation patients, and decreased with increasing recipient age. Non-exposure to antiviral drugs prior to liver transplantation was positively associated with sustained virological response. The overall survival of responders and non-responders was similar.
