HEPATITIS MONTHLY 2016; 16:e40357. [PMID: 27826320 PMCID: PMC5097177 DOI: 10.5812/hepatmon.40357] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/25/2016] [Accepted: 08/14/2016] [Indexed: 12/11/2022]
Abstract
CONTEXT The hepatitis C virus (HCV) is classified into seven genotypes and more than 100 subtypes. The treatment regimen, duration and efficacy of HCV therapy may vary according to the HCV genotype. Therefore, the HCV genotype should be determined prior to antiviral therapy. The objective of the current study was to review systematically all studies reporting the distribution of HCV genotypes in the countries that make up the Middle East. EVIDENCE ACQUISITION Articles were identified by searching electronic databases, including Scopus, PubMed and Google scholar, with timeline limits (articles published between 1995 and 2016). We carried out a systematic search regarding the distribution of HCV genotypes in Middle Eastern countries. RESULTS A total of 579 studies were identified by the electronic search. Of these, a total of 187 were identified as eligible papers including 60,319 patients who were meta-analyzed for pooled distribution of HCV genotypes. In Turkey, Israel, Cyprus, and Iran, genotype 1 was the most prevalent HCV genotype with rates of 82% (95% CI, 82%-83%), 68% (95% CI, 67%-69%), 68% (95% CI, 59%-77%), and 55% (95% CI, 54%-55%), respectively. In Egypt, Iraq, Saudi Arabia, and Syria, HCV genotype 4 was the most common genotype with rates of 86% (95% CI, 85%-88%), 60% (95% CI, 56%-64%), 56% (95% CI, 54%-55%), and 57% (95% CI, 54%-61%), respectively. On the basis of adjusted data, HCV genotype 4 was the most prevalent genotype in the Middle East region, with a rate of 74.7% (95% CI, 73.4%-76%), followed by genotype 1 at 15.1% (95% CI, 14.1%-16%). CONCLUSIONS Our results showed that HCV genotype 4 is the most prevalent genotype in the Middle East region. However, HCV genotype 1 is the most prevalent among non-Arab countries in the region including Turkey, Iran, Cyprus, and Israel.

Co-Infection of the Hepatitis C Virus With Other Blood-Borne and Hepatotropic Viruses Among Hemophilia Patients in Poland. HEPATITIS MONTHLY 2016; 16:e35658. [PMID: 27822257 PMCID: PMC5088732 DOI: 10.5812/hepatmon.35658] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 06/12/2016] [Accepted: 07/02/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND The prevalence of HCV infection in people with hemophilia is substantially higher than that in the general population (63% - 98%). Multiple transfusions and substitutive therapy have also been linked to a high risk of HBV and HIV transmission. However, the prevalence of other blood-borne viral infections in this population is less well known. OBJECTIVES This study aimed to assess the prevalence of co-infection with HBV and other blood-borne viruses in Polish HCV-infected hemophiliacs. METHODS Seventy-one individuals, the majority of whom were male (94.36%), who had congenital bleeding disorders (60 had hemophilia A, five had hemophilia B, and six had other factor deficiencies) and HCV infection, which was defined as the presence of positive anti-HCV antibodies, were included in this study. The study group was divided into two subgroups according to the year in which blood donors were first tested for HBsAg in Poland. The serological markers were screened using commercially available enzyme immunoassays according to the manufacturer's instructions. The molecular tests were performed using real-time PCR technology with commercial assays according to the manufacturer's instructions. RESULTS The spontaneous elimination rate of HCV RNA was 29.6%. The HCV genotype 1 was detected in 28 patients (65.1%), genotype 2 in one patient (2.3%), genotype 3 in 11 patients (25.6%), genotype 4 in two patients (4.7%), and a mixed infection with genotypes 1 and 4 was detected in one person (2.3%). Fifty-three patients (74.6%) were anti-HBc positive. Among the seven HBsAg(+) patients, three individuals were HBV-DNA positive. No occult hepatitis B was detected. In six HBsAg positive patients, the HCV RNA was positive, while one patient was also infected with HIV. The prevalence rate of past infection with HAV in the study group was 30.9%, with a tendency for a higher prevalence in older patients. The prevalence of CMV and EBV infection was high and similar to that seen in the general population. All the patients were HGV and HTLV-1 negative. CONCLUSIONS The diagnostics and management of infections with hepatotropic viruses, particularly HBV, are neglected in hemophilic patients. All patients with coagulation disorders and a history of exposure to non-inactivated blood products should be screened for blood-borne infections. The prevalence of other potentially blood-borne viral infections exhibited a pattern similar to that observed in the general population.

Abstract
Background/Aims Chronic hepatitis C (CHC) is a major comorbidity in patients with hemophilia. However, there are no published data on the efficacy of antiviral therapy in Korea. We assessed the safety and efficacy of combination therapy with peginterferon α-2a plus ribavirin for CHC in hemophilia. Methods Patients (n=115) were enrolled between March 2007 and December 2008. Seventy-seven patients were genotype 1 or 6, and 38 patients were genotype 2 or 3. We evaluated rapid virologic responses (RVRs), early virologic response (EVRs), end-of-treatment response (ETRs), sustained virologic response (SVRs), and relapses. Safety evaluations included adverse events and laboratory tests. Results Eleven patients were excluded from the study because they had been treated previously. Among the remaining 104 treatment-naïve patients, RVR was achieved in 64 (60.6%), ETR was achieved in 95 (91.3%), and SVR was achieved in 89 (85.6%). Relapse occurred in eight patients (8.9%). Common adverse events were hair loss (56.7%) and headache (51.0%). Common hematologic adverse events were neutropenia (22.1%), anemia (27.9%), and thrombocytopenia (3.8%). However, there were no serious adverse events such as bleeding. RVR was the only predictor of SVR in multivariate analysis. Conclusions Peginterferon α-2a plus ribavirin combination treatment produced a favorable response rate in CHC patients with hemophilia without serious adverse events.

Abstract
Single-nucleotide polymorphisms (SNPs) near the IL28B gene were identified as major predictors of treatment response (sustained virologic response--SVR) and spontaneous clearance of HCV. Haemophilia patients have the highest prevalence of HCV, and are a unique target for genetic studies. The Israeli population is ethnically heterogeneous; therefore, genetic variability is anticipated. To determine the IL28B haplotypes in HCV-infected haemophilia patients and association with SVR and spontaneous viral clearance. IL28B polymorphism at SNPs rs12979860 and rs8099917 was determined in sera obtained from 130 HCV-infected haemophilia patients. The frequency of the various haplotypes was analysed according to treatment response, spontaneous HCV clearance, viral load and degree of fibrosis. The CC haplotype at SNP rs12979860 was found in 31% of patients, whereas the TT genotype at SNP rs8099917 was detected in 57% of cases. SVR was achieved in 70% of patients carrying the CC haplotype (P = 0.0196 vs. CT/TT), and 50% of the TT genotype at SNP rs8099917 (P = 0.0227 vs. TG/GG). Thirty-five percent of patients carrying the CC haplotype and 26% with the TT genotype at SNP rs8099917 showed spontaneous clearance of HCV infection (P = 0.00262 vs. CT/TT; and P = 0.00371 vs. TG/GG respectively). The C-allele frequency was exceptionally high (71%) in immigrants from the Asian republics of Russia. In HCV-infected haemophilia patients, SVR was more commonly achieved among patients who had the CC (rs12979860) or TT (rs8099917) genotype. Likewise, patients who possess harbour the CC or TT genotypes were more likely to clear HCV infection spontaneously. A unique distribution of the CC genotype was observed in some ethnic groups.

Abstract
Serodiagnosis of infectious disease is often based on the detection of pathogen-specific antibodies in a patient's blood. For this, mixtures of pathogen-related antigens are used as bait to capture corresponding antibodies in solid phase immunoassays such as enzyme immunoassay (EIA). Western blots provide improved diagnostic power as compared with EIA due to the fact that the mixture of markers in the EIA well is resolved and tested as individual antigens on the Western blot. Hence, confirmation of EIA results is accomplished using the antigen arrays of Western blots. Here we took this approach one step further and tested the attributes of using epitope arrays in a diagnostic platform coined "combinatorial diagnostics." As a case in point, we tested a panel of phage-displayed epitope-based markers in the serodiagnosis of hepatitis C virus (HCV). The repertoire of HCV antigens was deconvoluted into panels of distinct linear and conformational epitopes and tested individually by quantitative EIA. Combinatorial diagnostics proved to be effective for the discrimination between positive and negative sera as well as serotyping of HCV.

Hepatitis C virus infection in the Middle East and North Africa "MENA" region: injecting drug users (IDUs) is an under-investigated population. Infection 2012; 40:1-10.

Abstract
PURPOSE Investigation of the injecting drug users (IDUs) population is becoming extremely critical and timely in light of the recent evidence that IDUs now act as the core of hepatitis C virus (HCV) epidemics in developed countries. The purpose of this article, therefore, is not only to review the epidemiology of HCV in the Middle East and North Africa (MENA) region, but also to see whether IDUs were adequately studied and whether harm reduction strategies to be applied for their protection have been set. METHODS A literature review was carried out of articles published within the last decade on HCV infection. RESULTS The gathered data showed that the population of IDUs is severely under-investigated throughout the whole region, possibly due to religious and cultural impediments. CONCLUSION In order to reduce the risk of HCV infection in IDUs, a set of recommendations are advanced emphasizing the urgent need for bio-behavioral studies in this population in order to help identify the source and mode of transmission and the genotypes of HCV involved. These results may allow the development of effective and, yet, socially acceptable intervention strategies. We believe that the role which IDUs play in sustaining HCV infection is also an under-investigated topic in many developing countries. Similar reviews and, hence, interventions should be initiated in these regions.

Abstract
BACKGROUND AND AIM Decisions on public health issues are dependent on reliable epidemiological data. A comprehensive review of the literature was used to gather country-specific data on risk factors, prevalence, number of diagnosed individuals and genotype distribution of the hepatitis C virus (HCV) infection in selected European countries, Canada and Israel. METHODOLOGY Data references were identified through indexed journals and non-indexed sources. In this work, 13,000 articles were reviewed and 860 were selected based on their relevance. RESULTS Differences in prevalence were explained by local and regional variances in transmission routes or different public health measures. The lowest HCV prevalence (≤ 0.5%) estimates were from northern European countries and the highest (≥ 3%) were from Romania and rural areas in Greece, Italy and Russia. The main risk for HCV transmission in countries with well-established HCV screening programmes and lower HCV prevalence was injection drug use, which was associated with younger age at the time of infection and a higher infection rate among males. In other regions, contaminated glass syringes and nosocomial infections continue to play an important role in new infections. Immigration from endemic countries was another factor impacting the total number of infections and the genotype distribution. Approximately 70% of cases in Israel, 37% in Germany and 33% in Switzerland were not born in the country. In summary, HCV epidemiology shows a high variability across Europe, Canada and Israel. CONCLUSION Despite the eradication of transmission by blood products, HCV infection continues to be one of the leading blood-borne infections in the region.

Abstract
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 alpha-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
Prior to the process of viral inactivation in the 1980s most haemophilic patients were infected with hepatitis C virus, currently one of the disease's main causes. The prevalence of infection by hepatitis C virus in haemophilic patients enrolled in the Hemocenter of the Regional University Hospital maintained by the State University of Maringá is evaluated from social and epidemiologic data and from serum and molecular tests. Possible association between haemophilia's type and severity, type of treatment, data of start of treatment and hepatic enzyme rates of Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) was verified. Sixty-nine haemophilic patients, 82.6% with haemophilia A and 17.4% with haemophilia B, in the 1 - 67 years age bracket, average age 22 years, were investigated. Whereas anti-HCV was investigated with third generation immunoenzymatic test and confirmed by HCV-RNA, LiPA technique determined genotypes. HCV-prevalence infection reached 37.7% and 21.7% respectively when antibody anti-HCV and HCV-RNA detection and associated significantly (p<0.05) with type of treatment, date of start of treatment and ALT and AST hepatic enzyme rates are taken into account. HCV genotype 1 predominated (53.3%) followed by genotype 3 (40.0%) and genotype 2 (6.7%). HCV predominance is high in haemophilic patients although infection has not been reported in patients under the age of 17.
