Introduction. HCV infection was common cause of morbidity and mortality in patients with hemophilia before 1986. We wanted to investigate the effect of treatment with combination therapy in HCV positive patients with hemophilia. Material and methods. The research included totally 13 persons afflicted with hemophilia and HCV infection out of 21 tested. The patients were submitted to laboratory and clinical tests as well as genotypization, whereby a different hepatitis C virus genetic adherence was observed. Parallel with this subcategory the other one was put into comparison, consisting of 12 patients afflicted with chronic C hepatitis, marked as non-hemophilics. The both subcategories were treated with combination antiviral therapy (peginterferon a-2a and ribavirin) during 48 weeks for genotype 1 and 4, in reference to 24 weeks for genotype 2 and 3. Within the treatment, clinical and laboratory side-effects were noticed, which did not require therapy interruption. A more frequent hemorrhage during the therapy was found within the hemophilics, rather than before initiliazing it. Results. After the statistical processing of the results (Students' t-test), statistically significant difference among these two subcategories was noticed as values for ALT (***p<0.0001) after 24 weeks of therapy, red blood cells (*p<0.05), haemoglobin and haematocrite (***p<0.0001) 24 weeks after therapy completing. By PCR examination of the patients, 6 months after the end of treatment, a sustained viral response (SVR) of the same percentage was registrated within both subcategories, which is even greater than what the other authors have described. Discussion. Main results were without important difference between two subgroups, except for higher number of spontanuous bleeding in group with hemophilia, which was somewhat expected. Most importantly, we didn't find any difference in SVR rates between groups. Conclusion. HCV positive patients with hemophilia could be successfully treated with combination therapy of peginterferon alfa-2a and ribavirin.

Abstract Background According to the WHO there are 185 million people infected with HCV in the world.Egypt has the highest prevalence of hepatitis C virus (HCV) in the world reaching 13% equating to an estimated 12 million Egyptians . HCV is one of the main causes of liver cirrhosis and hepatocellular carcinoma.HCV can develop kidney disease because of extrahepatic manifestations of HCV or as a disease process independent of the HCV infection.In addition, hemodialysis has been a risk factor for acquiring HCV infection. The prevalence of HCV infection is high in patients with ESRD, on hemodialysis ranges from 6% to 60% in different parts of the world. Several studies show that patients on hemodialysis have an increased overall mortality risk if they have chronic HCV when compared with those on dialysis who do not have HCV. Antiviral treatment in CKD patients can be complicated because many of the agents used for anti-HCV therapy can accumulate to toxic levels in the setting of renal impairment. Treatment of HCV compensated cirrhosis with the new DAA therapy Qurevo “ombitasvir/paritaprevir/ritonavir” with ribavirin in ESRD was approved in many countries. Aim of the study To evaluate the efficacy and safety of Qurevo/Ribavirin regimen in ESRD Egyptian patients who are infected with hepatitis C virus (HCV) . Patients and Methods A prospective cohort study evaluated the outcome of 12-week ombitasvir (NS5A inhibitor)/paritaprevir (NS3/4A protease inhibitor)/ritonavir with ribavirin combination therapy for 50 ESRD patients with HCV at the hepatic virology clinic at Ain Shams University hospital over a period of 15 months (from December 2016 to February 2018). The primary endpoint was sustained virologic response 12 weeks after therapy (SVR12). Results 50 ESRD patients with a mean age of 51.4 years, range from 23-77 years were enrolled.The SVR12 rate was 96% (48/50); 2 patients had virologic failure. As regards adverse events, the most frequent was fatigue/asthenia in 44 patients (88%) and worsening anemia (Hb dropped to &lt; 10 g/dl) in 42 patients (84%). GIT upset occurred in 10 patients (20%), sleep disorders in 8 patients (16%), decreased appetite in 8 patients (16%),respiratory distress in 6 patients (12%), headache, dizziness in 6 patients(12%). Muscle spasms in 4 patients (8%). Itching(pruritis) occurred in 3 patients(6%).2 patients (4%) were non-responders to treatment and another 2 (4%) were relapsers.Death occurred in 4 patients (8%) due to myocardial infarction, pulmonary edema, severe hypotension on hemodialysis sessions, shock due to blood loss in retroperitoneal hematoma following peritoneal dialysis. Hepatic decompensation, hypersenisitivity (angioedema), teratogenicity and drug interactions did not occur in any patient (0%).Other events occurred in 11 patients (22%). They were parenchymal liver changes in ultrasound at the end of therapy after being normal before therapy (in 3 patients), thrombocytopenia, increased alkaline phosphatase, hiccough, deterioration of hypertension, urinary tract infection, lower limb cellulitis, vaginal bleeding, chest infection(in 1 patient each). SVR12 was achieved in 100% of patients who had to stop or modify ribavirin dose;this means that Ribavirin absence didn’t affect the sustained viral response in these patients. Conclusion Our results confirm the efficacy of Qurevo “ombitasvir/paritaprevir/ritonavir” with Ribavirin combination therapy in ESRD patients with HCV infection, with anemia as the most frequent adverse event.

Background & Aims: Smoking has multiple effects on factors influencing hepatitis C and antiviral therapy, including lipid metabolism, fibrosis, platelet count and adherence aspects. The aim of this analysis was to determine the impact of smoking on hepatitis C virus antiviral therapy. Methods: Data of two cohorts of an observational multicenter study including therapy-naïve patients infected with genotype 1 hepatitis C virus (HCV) treated with dual antiviral therapy (n=7,796) with pegylated interferon alpha 2a in combination with ribavirin, or triple antiviral therapy (n=1,122) containing telaprevir or boceprevir, were analysed. Results: In the univariate matched pair analysis of dual antiviral therapy patients (n=584), smoking was significantly associated with lower sustained viral response rates (p=0.026, OR 0.69 CI: 0.50 – 0.96). The effect of smoking on sustained viral response remained significant (p=0.028, OR 0.67 CI: 0.47 – 0.96) in the multivariate analysis when adjusting for all other baseline parameters with a significant association in the univariate analysis, i.e. diabetes, fibrosis, body mass index, transaminases and baseline viral load. Under protease inhibitors the influence of smoking on virological response did not arise. Conclusions: Smoking has a negative impact on antiviral therapy in naïve patients infected with HCV genotype 1 independently of age, gender, history of drug use or alcoholic liver disease. The effects of smoking might be overcome by the new antiviral agents.Abbreviations: APRI: AST to platelet ratio index; DAA: direct antiviral agent; DT: dual antiviral therapy; EoTR: end of treatment response; RVR: rapid virological response; EVR: early virological response; HCV: hepatitis C virus; IFN: interferon alpha; MPA: Matched Pair Analysis; NS: non-smokers; PEG-IFN: pegylated interferon alpha 2a; PI: protease inhibitor; RBV: ribavirin; SAE: serious adverse event; SOC: standard of care; S: smokers; SVR: sustained viral response.

The present study assessed the clinical significance of hepatitis C virus (HCV) genotypes and their influence on response to long term recombinant-interferon-alpha (r-IFN-<FONT FACE="Symbol">a</FONT>) therapy in Brazilian patients. One hundred and thirty samples from patients previously genotyped for the HCV and with histologically confirmed chronic hepatitis C (CH-C) were evaluated for clinical and epidemiological parameters (sex, age, time of HCV infection and transmission routes). No difference in disease activity, sex, age or mode and time of transmission were seen among patients infected with HCV types 1, 2 or 3. One hundred and thirteen of them were treated with 3 million units of r-IFN-<FONT FACE="Symbol">a</FONT>, 3 times a week for 12 months. Initial response (IR) was significantly better in patients with genotype 2 (100%) and 3 (46%) infections than in patients with genotype 1 (29%) (p < 0.005). Among subtypes, difference in IR was observed between 1b and 2 (p < 0.005), and between 1b and 3a (p < 0.05). Sustained response (SR) was observed in 12% for (sub)type 1a, 13% for 1b, 19% for 3a, and 40% for type 2; significant differences were found between 1b and 2 (p < 0.001), and between 1b and 3a (p < 0.05). Moreover, presence of cirrhosis was significantly associated with non response and response with relapse (p < 0.05). In conclusion, non-1 HCV genotype and lack of histological diagnosis of cirrhosis were the only baseline features associated with sustained response to treatment. These data indicate that HCV genotyping may have prognostic relevance in the responsiveness to r-IFN-<FONT FACE="Symbol">a</FONT> therapy in Brazilian patients with chronic HCV infection, as seen in other reports worldwide.

BACKGROUND: Hepatitis C is a blood-borne, infectious, viral disease that is caused by a hepatotropic virus called Hepatitis C virus (HCV).AIM: The aim of this study is to determine the prevalence of active HCV infection (HCV–RNA) in the cases that were anti-HCV positive.MATERIAL AND METHODS: Plasma of 301 high-risk for HCV infection consecutive from University Hospital Centre “Mother Theresa” Tirana-Albania, during January 2007 to December 2010 was included in this study. To identify the presence of HCV RNA, the samples were examined by Cobas Amplicor HCV test (qualitative method).RESULTS: From 301 samples analyzed in total, 214 of them resulted positive for the presence of HCV-RNA's, corresponding to a prevalence of 71.1%, with 95% CI interval [65.8 - 75.9] for value of χ2 = 52.7 p value <0.0001. Divide by the sex 56% were males and 44% females, with statistically significant difference between them for value χ2 =4306 p value=0.0380. Among the age groups the highest prevalence was observed in the age groups > 25 years with a significant difference with other age groups for p value <0.001.CONCLUSION: Among tested samples, 71.1 % were confirmed to be positive for HCV –RNA infections. The prevalence of male was highest compared to female. For males and females infected the prevalence was highest in the age group of > 25 years.

ABSTRACT Hepatitis C virus (HCV) infection is an independent risk factor for developing chronic renal impairment and end-stage renal disease. Limited treatment options are available for HCV genotype 2, 3, 5, and 6 infections in patients with an estimated glomerular filtration rate (eGFR) of <30 ml/min. Glecaprevir and pibrentasvir are active against all six major HCV genotypes, are primarily excreted in the bile, and have minimal renal elimination. Therefore, combined treatment with these direct-acting antivirals may be useful for patients with HCV infection and chronic kidney disease. A phase 1, multicenter, open-label study evaluated the effects of renal impairment on the pharmacokinetics and safety of glecaprevir-pibrentasvir. In substudy 1, 38 subjects with stage 2 to 5 chronic kidney disease who were not on dialysis or who had normal renal function received single doses of the combination of 300 mg glecaprevir and 120 mg pibrentasvir. In substudy 2, 8 subjects requiring hemodialysis received single doses of the combination of 300 mg glecaprevir and 120 mg pibrentasvir under dialysis and nondialysis conditions. Regression analyses demonstrated increased glecaprevir and pibrentasvir plasma exposures, as determined by the area under the curve, with decreasing renal function, up to 56% and 46%, respectively, in subjects with an eGFR of <15 ml/min/1.73 m 2 . In dialysis-dependent subjects, glecaprevir and pibrentasvir exposures were similar (≤18% difference) when study drugs were administered before hemodialysis or on a nondialysis day. Adverse events were mostly mild, with the most common being self-limited fatigue (3 subjects). The study findings support the clinical evaluation of glecaprevir-pibrentasvir without dose adjustment in HCV-infected subjects with renal impairment. (This study has been registered at ClinicalTrials.gov under registration number NCT02442258.)

Abstract: Hepatitis C virus infection causes approximately 4 million new infections worldwide, and 399 000 deaths due to its complications, cirrhosis and hepatocellular carcinoma (HCC). Microenvironmental changes, chronic inflammation, oxidative stress, endoplasmic reticulum stress caused by HCV infection, via genetic and epigenetic changes can result in primary liver cancer during decades. The direct oncogenic property of HCV is wellknown. The transforming effect of four HCV proteins (core, NS3, NS4B, NS5A) has been proven. Effective antiviral therapy, sustained viral response decreases the HCV-related general and liver-related mortality. Interferon-based therapy reduces the risk of HCC development. Shorter therapy with direct acting antiviral agents (DAA) has higher efficacy, fewer side-effects. Publications have reported the unexpected effects of DAA. The authors review the articles focusing on the occurrence of HCC in connection with DAA therapies. There is a need for prospective, multicentric studies with longer follow-up to examine the risk of HCC formation. After antiviral therapy, HCC surveillance is of high importance which means abdominal ultrasound every 3–6–12 months in sustained viral response patients as well. Orv Hetil. 2019; 160(22): 846–853.
