Abstract
The introduction of clotting factor concentrates has substantially improved the lives of people with clotting factor deficiencies. Unfortunately, the transmission of blood-borne viral infections through these plasma-derived products led to a huge epidemic of human immunodeficiency virus and viral hepatitis in people with haemophilia (PWH). In a significant proportion of PWH exposed to these viruses, the ensuing decades-long chronic infection resulted in excess morbidity and mortality. Fortunately, developments in the safety of blood products, as well as vaccination and highly effective antiviral treatments have improved the prospects of PWH. The present article reviews the background of the viral hepatitis epidemic in PWH, the natural history of hepatitis B and C infections and their long-term management.

Abstract
An option currently being explored for the treatment of COVID-19 is the use of interferons (INFs), either alone or in combination with other antiviral agents. INFs are known to shift the metabolism of tryptophan (TRP) away from its role as a precursor of serotonin. For some patients, reduction in TRP levels may either expose an underlying vulnerability to depression or trigger a de novo episode of depression. This Commentary discusses the pathway involved and recommends in-hospital augmentation with foods or supplements that increase TRP levels for COVID-19 patients treated with INFs. Selective serotonin reuptake inhibitors may also be tried if the depressive symptomatology is not short-lived.

Abstract
Background Interferon therapy is used as a line of treatment of chronic hepatitis C virus (HCV) in several areas of the world including Egypt. Objective Our aim was to investigate the value of hepatic progenitor cells (HPCs) in predicting response of patients with chronic HCV, genotype 4 to pegylated interferon (PEGIFN) plus ribavirin (RBV) therapy. Methods Pre-treatment liver biopsies obtained from 110 patients with chronic HCV, genotype 4 were examined immunohistochemically for HPCs using cytokeratin19. The mean number of HPCs as ductular reaction (DR) and as isolated progenitor cells (IPCs) was counted in each case. The patients were classified into: those with sustained virological response (SVR) and those who did not achieve SVR. The results were compared between the two groups. Also, the relationships between HPCs and other clinico-pathologic variables were estimated using multivariate analysis. Results The mean number of HPCs was the only independent predictor of therapeutic response, being significantly higher in non-responders (P = 0 for DR and P = 0.03 for IPCs). On the other hand, fibrosis stage and steatosis were the only independent factors which showed a significant direct association with the mean number of HPCs in the form of DR and IPCs (P = 0 for each). Conclusion The number of HPCs provides prognostic information in chronic HCV since it is significantly associated with stage of fibrosis. More importantly, it can be used as a marker to predict response of patients with chronic HCV to PEGIFN plus RBV therapy.

Psychiatric side effects of pegylated interferon-α and ribavirin therapy in Iranian patients with chronic hepatitis C: A meta-analysis. Exp Ther Med 2018; 16:971-978. [PMID: 30116347 DOI: 10.3892/etm.2018.6255] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Accepted: 02/08/2018] [Indexed: 12/19/2022] Open
Abstract
An estimated 185 million people worldwide are infected with hepatitis C virus (HCV). Combination therapy with pegylated interferon-α (peg IFN) and ribavirin is the first line of treatment against the psychiatric side effects, including mood disorders, anxiety and irritability. In the present study, all of the studies electronically published between 2000 and 2016 were retrieved using databases including Scopus, PubMed, Institute for Scientific Information, Science Direct and Google Scholar. All of the articles were independently evaluated by two reviewers and the results were compared, followed by removal of duplicate, irrelevant and re-published studies after reviewing. The studies were assessed based on the heterogeneity of their results using the Cochrane test and I2 analysis. All groups included neuropsychiatric side effects, fatigue was reported at the highest rate in 60.41% [95% confidence interval (CI)=39.18-81.64%] and insomnia was reported at a lower rate in 16.28% of cases (95% CI=6.59-25.98%). In conclusion, the present meta-analysis indicated that treatment with peg IFN + ribavirin or interferon only is associated with a wide range of neuropsychiatric side effects, including fatigue, mood disorders, anxiety, irritability, emotional ability and agitation.

Abstract
There are over 10 million hepatitis C virus (HCV)-infected patients in Pakistan. For these patients, a combination of interferon with ribavirin is the most economical and easily available treatment. Single-nucleotide polymorphisms in interleukin genes have been reported to be associated with the pathogenesis and clearance of HCV, and sustained virologic response (SVR). An interleukin 28B (IL28B) gene polymorphism has been shown to modify treatment outcomes, but the effects of interleukin 10 (IL10) polymorphisms have not been previously assessed in the Pakistani population. The present study was conducted with 302 subjects categorized into two groups: 100 healthy volunteers (Group I) and 202 patients with chronic HCV (Group II). Patients within Group II were further divided into two subgroups according to therapeutic response: SVR (responders = 132) and NR (non-responders/relapsers = 70). IL28B (rs8099917, rs12979860) and IL10 (rs1800872, rs1800871, rs1800896) gene polymorphisms were studied in all subjects. A significant difference in the distribution of IL28B rs12979860C/T genotypes between the two groups (p<0.05) was observed, while of the three IL10 polymorphisms, a significant difference was only shown for rs1800896 A/G. Haplotype analysis (IL28B and IL10) showed a significant association of TTGTC and TTGTA when comparing the groups. There was a strong association of the favorable alleles rs8099917T and rs12979860C in the SVR group as compared with the NR group (p<0.05), and rs1800896 also showed an association with the SVR group as compared to the NR group (p<0.004). Haplotype analysis showed significant associations when comparing the SVR and NR subgroups, i.e. TCATC (p=0.009), TTGTA (p=0.005), TCATA (p<0.0005), TCACA (p=0.002), GTGCC (p=0.002) and TCGTC (p=0.005). IL28B (rs8099917 and rs12979860) and IL10 (rs1800896) polymorphisms alone, or in combination, are good predictors of therapeutic response in HCV-3a patients.

Abstract
BACKGROUND The aim of this study was to determine whether two polymorphisms of the human interferon lambda 4 (IFNL4) gene (rs12979860 and rs8099917) can predict sustained virologic response (SVR) following antiviral therapy in patients with inherited bleeding disorder and chronic hepatitis C (CHC). METHODS This retrospective study was conducted on 294 patients with congenital bleeding disorder and CHC who were treated with Peg-Interferon-α (PegIFN) and Ribavirin (RBV). Baseline patient and viral parameters were measured and analyzed statistically to assess their combined and individual contributions to SVR prediction. RESULTS The most prevalent variants of rs12979860 and rs8099917 identified among the study patients were CT (45.9%) and TT (57.6%), respectively. Overall, SVR was achieved in 69% of the study patients. The rate of SVR was lower in patients with HCV genotype-1 than in those with HCV genotype-3 (62% vs 88%; P<.001; OR=0.23). Multivariate analysis of SVR predictors in patients with HCV genotype-1 infection included age (<24 years), BMI (<25), absence of cirrhosis, HCV RNA level (<400 000 IU/mL), rs8099917 TT and rs12979860 CC, all of which were associated with a higher SVR rate. In HCV genotype-3 infection, only rs12979860 CC was significantly associated with SVR. CONCLUSION These results demonstrate that polymorphisms of the IFNL4 gene are highly associated with SVR to PegIFN and RBV combination therapy in patients with a congenital bleeding disorder and CHC. Assessment of rs12979860 and rs8099917 genotypes can guide physicians in choosing an optimal treatment regimen, including less expensive therapies that may only be available in many geographic locales.

Abstract
Background: A dinucleotide variant rs368234815 in interferon lambda 4 (IFNL4) gene was recently found to be associated with the hepatitis C virus (HCV) treatment response. This study aimed to assess the impact of IFNL4 rs368234815 polymorphism on treatment response to pegylated-IFN alpha (Peg-IFN-α) and ribavirin (RBV) in hemophilic patients with chronic hepatitis C (CHC). Materials and Methods: In this retrospective study, 92 hemophilic patients with CHC who were treated with Peg-IFN-α/RBV were investigated. Single-nucleotide polymorphisms (SNPs) in IFNL genomic region including rs368234815, rs12979860, and rs8099917 were analyzed by DNA sequencing. Results: Of the 92 patients, 63 (68.5%) achieved sustained virological response (SVR). Of the 43 patients with rs368234815 TT/TT genotype, 36 (83.7%) achieved SVR, while in 49 patients with non-TT/TT genotypes, 27 (55.1%) achieved SVR. Other pretreatment parameters predicted SVR were patients’ body mass index, HCV genotype, rs12979860, and rs8099917 SNPs. In multivariate analysis, all above-mentioned parameters except rs8099917 remained as predictors of SVR. IFNL4 rs368234815 was a strong predictor of SVR; however, the prediction power of this SNP was the same as that of rs12979860 SNP in the patients of the current study. Conclusion: IFNL4 rs368234815 SNP can be considered for decision-making in the treatment of HCV-infected patients.

Abstract
AIM This study explores the potential role of a novel interferon-containing regimen for treatment of patients with chronic hepatitis C (CHC) and underlying haemophilia. METHODS This trial (NCT01741545) was an open-label, non-randomized phase 3 study, which included adult haemophiliacs with hepatitis C virus (HCV). Patients with HCV genotypes (GT)-2 or -3 were treated with Lambda-IFN/ribavirin (RBV)/daclatasvir (DCV) for 12 weeks (cohort A). Patients with HCV GT-1b or -4 were treated with Lambda-IFN/RBV/DCV for 12 weeks, followed by Lambda-IFN/RBV for an additional 12 weeks (cohort B). The primary endpoint was the proportion of patients with a sustained virologic response at post-treatment follow-up week 12 (SVR12). Clinical development of Lambda-IFN was discontinued during this trial leading to study termination before a 24-week post-treatment follow-up was obtained for all participants. RESULTS Overall, 51 patients were treated (cohort A, n = 12; cohort B, n = 39). The proportion of patients achieving SVR12 was 92% in cohort A and 90% in cohort B. Therapy was generally well tolerated. The most common adverse events (AEs) were related to elevations in serum transaminases and/or bilirubin. Five serious AEs, four discontinuations due to AEs, and no deaths were reported. The rate of grade 3-4 bilirubin elevations was 17-18% across cohorts. CONCLUSION Lambda-IFN/RBV/DCV treatment demonstrated a high SVR rate and was generally well tolerated with a safety profile consistent with expectations for this special patient population. This study supports use of DCV as part of a combination treatment regimen for haemophiliacs with CHC.

Abstract
Occult hepatitis C virus (HCV) infection is a new form of chronic HCV infection described by the presence of the genomic HCV-RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) samples, and undetectable levels or absence of HCV-RNA and in the absence or presence of anti HCV antibodies in the plasma specimens. The aim of the present study was to evaluate the occurrence of occult HCV infection (OCI) among Iranian subjects infected with human immunodeficiency virus (HIV) using RT-nested PCR. From March 2014 until April 2015, 109 Iranian patients with established HIV infection were enrolled in this cross-sectional study. After extraction of viral RNA from the plasma and PBMC samples, HCV-RNA status was examined by RT-nested PCR using primers from the 5'-NTR. HCV genotyping was conducted using RFLP analysis. For the confirmation of HCV genotyping by RFLP method, the PCR products were sequenced. Of the 109 patients, 50 were positive for antibodies against HCV. The HCV-RNA was detected in PBMC specimens in 6 (10.2%) out of the total 59 patients negative for anti-HCV Abs and undetectable plasma HCV-RNA and also from 4 (8.0%) out of the total 50 patients positive for anti-HCV Abs and undetectable plasma HCV-RNA. HCV genotyping analysis showed that 6 (60.0%) patients were infected with HCV subtype 3a, 3 (30.0%) were infected with HCV subtype 1a and 1 (10.0%) patient was infected with HCV subtype 1b. This study revealed the incidence of OCI (9.2%) in HIV-infected Iranian patients. Hence, designing prospective studies focusing on the detection of OCI in these patients would provide more information. J. Med. Virol. 88:1960-1966, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
Scarce data is available on the efficacy of Pegylated Interferon (Peg-IFN) and Ribavirin (RBV) combination therapy in hemophilic children with chronic hepatitis C. The aim of this study was to evaluate the efficacy of Peg-IFN and RBV combination therapy for hemophilic children infected with hepatitis C virus (HCV) in comparison with adult hemophilic patients with chronic hepatitis C. A case-control study comprised 31 pediatric hemophilic patients ages under 16 years with previously untreated HCV genotype-1 or -3 infection as the case group and 62 treatment naive adult hemophilic patients with chronic HCV infection as the control group. Case and control groups were matched case by case according to HCV genotype, HCV RNA level and rs12979860 polymorphism. All patients in the case and control groups were treated with Peg-IFN and RBV for 24-48 weeks according to HCV genotype. Sustained virological response (SVR) was achieved in 26 (83.9%) pediatric patients and in 39 (62.9%) of adult patients (P = 0.05, OR = 3.07, 95%CI = 1.03-9.09). The rate of SVR was not different according to HCV genotype, HCV RNA level, and rs12979860 polymorphism in both studied groups whereas achieving early virological response was associated with achievement of SVR in both groups. The efficacy of Peg-IFN and RBV combination therapy in hemophilic children with chronic hepatitis C is higher than that of adult hemophilic patients.

The Association of Substitutions in the Hepatitis C Virus Subtype 1b Core Gene and IL28B Polymorphisms With the Response to Peg-IFNα-2a/RBV Combination Therapy in Azerbaijani Patients. HEPATITIS MONTHLY 2016; 16:e35597. [PMID: 27313635 PMCID: PMC4908614 DOI: 10.5812/hepatmon.35597] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 03/23/2016] [Accepted: 04/12/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND The hepatitis C virus (HCV) infection has been identified as a leading cause of progressive liver diseases worldwide. Despite new treatment strategies, pegylated interferon alfa-2a (Peg-IFNα-2a), in combination with ribavirin (RBV), still represents the gold standard of therapy for hepatitis C in developing countries. OBJECTIVES The aim of this study was to investigate the association of substitutions in the HCV subtype 1b (HCV-1b) core protein and the rs12979860 polymorphism in the interleukin 28B gene (IL28B) with the response to Peg-IFNα-2a/RBV combination therapy in Azerbaijani patients. PATIENTS AND METHODS A total of fifty-one chronically HCV-1b-infected Azerbaijani patients were enrolled in this cross-sectional study from March 2010 to June 2015. After RNA extraction from pre-treatment plasma, the core region of the HCV genome was amplified using the nested reverse transcription (RT) polymerase chain reaction (PCR) method, followed by standard sequencing. In addition, genomic DNA was extracted from peripheral blood mononuclear cell (PBMC) specimens, and the rs12979860 single nucleotide polymorphism (SNP) was identified using a PCR-restriction fragment length polymorphism (PCR-RFLP) assay. RESULTS In this study, a significant association was observed between the non-responders and relapsers to antiviral therapy and substitutions in the HCV-1b core region at positions 43 (R43K, P = 0.047), 70 (R70Q, P < 0.001), 91 (M91L, P = 0.037), and 106 (S106N, P = 0.018). Concerning the IL28B polymorphism, the results showed that sustained virological response was significantly associated with homozygous CC patients (P = 0.009) as compared with other genotypes, while homozygous TT subjects were associated with HCV relapse after therapy (P = 0.006). CONCLUSIONS The data of the present study suggest that amino acid substitutions at position 43, 70, 91, and 106 in the HCV-1b core protein are correlated with the response to the Peg-IFNα-2a/RBV treatment in Azerbaijani patients with chronic hepatitis C. Moreover, host genetic polymorphisms, such as those of the IL28B locus, might be useful for predicting the responsiveness to Peg-IFNα-2a/RBV combination therapy against HCV.

Abstract
Objectives This study aimed to evaluate the specificity, sensitivity, cost, and turn-around time of three methods of gene polymorphism analysis and to study the relationship between IL28B rs12979860 and SVR rate to pegIFN-α/RVB therapy among patients with chronic hepatitis C. Methods A total of 100 samples from chronic hepatitis C patients were analyzed in parallel using the three methods: direct sequencing, real-time polymerase chain reaction (PCR), amplification refractory mutation system (ARMS)-PCR. Results The different profiles for IL28B rs12979860 alleles (CC, CT, and TT) obtained with PCR-RFLP, ARMS-PCR, and direct sequencing were consistent among the three methods. Prevalence of rs12979860 genotypes CC, CT and TT in HCV genotype 1a was 10(19.6%), 35(68.6%), and six (11.8%), respectively, and in HCV genotype 31, it was 13(26.5%), 31(63.3%), and five (10.2%), respectively. No significant difference was seen between rs12979860 genotype and HCV genotype (p = 0.710). Conclusion Screening by ARMS – PCR SNOP detection represents the most efficient and reliable method to determine HCV polymorphisms in routine clinical practice.

Abstract
AIM To evaluate the efficacy of pegylated interferon in Iranian chronic hepatitis C patients in relation to interferon-λ (IFNL) polymorphisms. METHODS This study enrolled patients with chronic hepatitis C referred to the Tehran Blood Transfusion Hepatitis Clinic in 2011. Patients were included in the study if they had no concomitant hepatic illness, were negative for human immunodeficiency virus antibodies, and had no prior history of treatment with any type of pegylated interferon. Patients were treated with 180 μg pegylated interferon alpha-2a (Pegaferon(®)) weekly and 800-1200 mg ribavirin daily for 24 or 48 wk depending on weight and hepatitis C virus (HCV) genotype. Blood samples were collected from patients to obtain DNA for determination of IFNL rs12979860 and rs8099917 polymorphisms. The virologic response in patients was then evaluated and compared between the different IFNL genotypes. RESULTS A total of 152 patients with a mean age of 41.9 ± 10.0 years were included in the study, of which 141/152 were men (92.8%). The most frequent HCV genotype was type-1, infecting 93/152 (61.2%) patients. Sustained virologic response (SVR) was achieved in 81.9% of patients with HCV genotype-1 and 91.1% of patients with HCV genotype-3. Treatment success was achieved in 91.2% (52/57) of patients with the IFNL rs12979860 CC genotype and 82.1% (78/95) in those with other genotypes. Similar treatment response rates were also observed in patients with rs8099917 TT (39/45; 86.7%) and non-TT (61/68; 89.7%) genotypes. Univariate analyses identified the following factors which influenced treatment response for inclusion in a multivariate analysis: age, HCV RNA level, stage of liver fibrosis, rs12979860 CC genotype, and aspartate transaminase level. A logistic regression analysis revealed that only the rs12979860 CC genotype was significantly associated with achievement of SVR (OR = 6.2; 95%CI: 1.2-31.9; P = 0.03). CONCLUSION The rs12979860 CC genotype was associated with SVR in patients receiving pegylated interferon plus ribavirin, however, the SVR rate in other rs12979860 genotypes was also relatively high.

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
BACKGROUND A recent genome-wide association study (GWAS) on patients with chronic hepatitis C (CHC) treated with peginterferon and ribavirin (pegIFN-α/RBV) identified a single nucleotide polymorphism (SNP) on chromosome 19 (rs12979860) which was strongly associated with a sustained virological response (SVR). The aim of this study was twofold: to study the relationship between IL28B rs12979860 and sustained virological response (SVR) to pegIFN-α/RVB therapy among CHC patients and to detect the rs12979860 polymorphism by high resolution melting curve (HRM) assay as a simple, fast, sensitive, and inexpensive method. MATERIALS AND METHODS The study examined outcomes in 100 patients with chronic hepatitis C in 2 provinces of Iran from December 2011 to June 2013. Two methods were applied to detect IL28B polymorphisms: PCR-sequencing as a gold standard method and HRM as a simple, fast, sensitive, and inexpensive method. RESULTS The frequencies of IL28B rs12979860 CC, CT, and TT alleles in chronic hepatitis C genotype 1a patients were 10% (10/100), 35% (35/100), and 6% (6/100) and in genotype 3a were 13% (13/100), 31% (31/100), and 5% (5/100), respectively. In genotype 3a infected patients, rs12979860 (CC and CT alleles) and in genotype 1a infected patients (CC allele) were significantly associated with a sustained virological response (SVR). The SVR rates for CC, CT and TT (IL28B rs12979860) were 18%, 34% and 4%, respectively. Multiple logistic regression analysis identified two independent factors that were significantly associated with SVR: IL-28B genotype (rs 12979860 CC vs TT and CT; odds ratio [ORs], 7.86 and 4.084, respectively), and HCV subtype 1a (OR, 7.46). In the present study, an association between SVR rates and IL28B polymorphisms was observed. CONCLUSIONS The HRM assay described herein is rapid, inexpensive, sensitive and accurate for detecting rs12979860 alleles in CHC patients. This method can be readily adopted by any molecular diagnostic laboratory with HRM capability and will be clinically beneficial in predicting treatment response in HCV genotype 1 and 3 infected patients. In addition, it was demonstrated that CC and CT alleles in HCV-3a and the CC allele in HCV-1a were significantly associated with response to pegIFN-α/RBV treatment. The present results may help identify subjects for whom the therapy might be successful.

Abstract
BACKGROUND Treatment with Peginterferon Alpha-2b plus Ribavirin is the current standard therapy for chronic hepatitis C (CHC). However, many host related and viral parameters are associated with different outcomes of combination therapy. OBJECTIVES The aim of this study was to develop an artificial neural network (ANN) model to predetermine individual responses to therapy based on patient's demographics and laboratory data. PATIENTS AND METHODS This case-control study was conducted in Tehran, Iran, on 139 patients divided into sustained virologic response (SVR) (n = 50), relapse (n = 50) and non-response (n = 39) groups according to their response to combination therapy for 48 weeks. The ANN was trained 300 times (epochs) using clinical data. To test the ANN performance, the part of data that was selected randomly and not used in training process was entered to the ANN and the outputs were compared with real data. RESULTS Hemoglobin (P < 0.001), cholesterol (P = 0.001) and IL-28b genotype (P = 0.002) values had significant differences between the three groups. Significant predictive factor(s) for each group were hemoglobin for SVR (OR: 1.517; 95% CI: 1.233-1.868; P < 0.001), IL-28b genotype for relapse (OR: 0.577; 95% CI: 0.339-0.981; P = 0.041) and hemoglobin (OR: 0.824; 95% CI: 0.693-0.980; P = 0.017) and IL-28b genotype (OR: 2.584; 95% CI: 1.430-4.668;P = 0.001) for non-response. The accuracy of ANN to predict SVR, relapse and non-response were 93%, 90%, and 90%, respectively. CONCLUSIONS Using baseline laboratory data and host characteristics, ANN has been shown as an accurate model to predict treatment outcome, which can lead to appropriate decision making and decrease the frequency of ineffective treatment in patients with chronic hepatitis C virus (HCV) infection.

Abstract
Interferons are able to exert an antiviral effect against hepatitis C virus (HCV) infection via induction of interferon-stimulated genes (ISGs). This study tested whether differential expression of an important ISG with antiviral properties, tripartite motif 22 (TRIM22), correlates with a response to Peg-IFNα-2a/RBV combination therapy in treatment-naive patients with chronic hepatitis C. A total of 32 patients with chronic hepatitis C were enrolled in this study and received standard Peg-IFNα-2a/RBV combination therapy. HCV viral load was measured during treatment, at the end of treatment, and 6 months later to determine the treatment outcome. Quantitative real-time PCR was used to assess the expression levels of TRIM22 in peripheral blood mononuclear cells (PBMCs) of the patients before antiviral therapy. Of the 32 patients, 26 (81.3%) were males. In this study, there were 16 (50%) individuals with a sustained virologic response (SVR), and a virologic relapse was observed in the remaining half of the subjects. Testing for the presence of genomic HCV RNA in blood during therapy revealed a rapid virologic response (RVR) in 10 (31.2%) and a partial and complete early virologic response (EVR) in 8 (25%) and 24 (75%) of the cases, respectively. TRIM22 mRNA levels were significantly higher in patients with a sustained virologic response than in relapsers (P = 0.002) and in patients with a rapid virologic response than in the others (P = 0.040). No statistically significant difference was seen in the expression of TRIM22 between patients with a partial early virologic response and a complete early virologic response. This study showed that pretreatment upregulation of TRIM22 may be associated with responsiveness to Peg-IFNα-2a/RBV combination therapy.

Abstract
The cross-border symposium on hepatitis C, entitled “why treating now?” was held on 15th May 2013 during the 5th International Tehran Hepatitis Congress. The present report summarizing communicated insights during this symposium is intended to help health care providers to make well-informed decisions when treating patients with chronic hepatitis C (CHC). Since today’s evolving science of hepatitis C management has introduced new treatment options, one should be well-versed about the potential benefits as well as untoward effects or practical challenges when using these regimens. In addition to outline HCV treatment advances, this symposium focused on the central question that why eligible patients with hepatitis C who may mostly benefit from the currently available protease inhibitors, should be treated now rather than be waited for the future therapies. Moreover, an overview of long term local experience with protease inhibitors in our challenging hepatitis C patients was presented during this interactive symposium.

[PMID: 24032043 PMCID: PMC3759779 DOI: 10.5812/hepatmon.11038] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2013] [Revised: 04/08/2013] [Accepted: 05/25/2013] [Indexed: 12/11/2022]
Abstract
BACKGROUND Various aspects of adherence to HCV treatment such as frequency, risk factors as well as causes of non-adherence, and its real role in clinical and virological outcome of the infected patients have remained largely unknown. OBJECTIVES The current study aimed to evaluate patients' adherence to anti-HCV medications in Iran. MATERIALS AND METHODS From October 2010 to March 2011, socio-demographic characteristics, features of HCV infection, clinical properties, and habitual history of 190 patients were collected. Adherence of each patient to anti-HCV medications was determined at months 1, 3, and 6 of treatment by self-reporting and pill or empty ampoule counting. Adherence to anti-HCV treatment regimen was determined based on the 80/80/80 rule. RESULTS Adherence rate to interferon, ribavirin, or a combination of them over the first 6 months of therapy in Iranian HCV patients measured by both methods of self-reporting and pill counting were 35.4-65.8%, 46.3-56.8%, and 28.4-51.1%, respectively. Delay in receiving new prescription, financial issues, and adverse drug reactions were the most common causes of non-adherence in the patients. Adherence to ribavirin was identified as an independent predictor of achieving the end of treatment response, or sustained virological response. CONCLUSIONS The rate of adherence to interferon and ribavirin varied significantly according to the method of calculation. Over the treatment course, adherence to interferon alpha and ribavirin, each or their combination, diminished significantly.

Abstract
We report a case of successful treatment of chronic hepatitis C infection with telaprevir-based triple therapy in a patient with hemophilia A complicated by factor VIII inhibitor. A twenty-two years old male with hereditary hemophilia A and high-titer factor VIII inhibitor was taking maintenance doses of recombinant factor VIII. He visited our clinic for treatment of his chronic hepatitis C with the newly instituted protease inhibitor based therapy. He was diagnosed with hepatitis C genotype 1a at one year of age. He was initiated on telaprevir, ribavirin and peg-interferon for treatment of hepatitis C and qualified for response-guided therapy. He completed treatment at 24 wk with minimal adverse effects. Notably, after 4 wk of hepatitis C treatment, his factor VIII inhibitor screen was negative and the dose for recombinant factor VIII decreased by half of the initial dosing before he was treated for hepatitis C. We suspect that suppressing hepatitis C may help decrease factor VIII inhibitor level and the need for recombinant factor VIII.

Abstract
BACKGROUND Despite significant advances in the treatment of chronic hepatitis C in the past decades, factors which can affect response rates to combination therapy; peginterferon and ribavirin, are still under study and reaching sustained virological response (SVR) is affected by several different factors. OBJECTIVES To investigate predictor factors contributing to SVR in Iranian patients. PATIENTS AND METHODS The present non-randomized, clinical trial was conducted on 100 patients referred to the Tehran Hepatitis Center in 2009-2011. The patients were administered combined peginterferon α-2a-ribavirin treatment, based on the standard protocol of the Iranian Ministry of Health. At the end of the treatment, the SVR rate and predictors were evaluated. RESULTS The mean age of the patients was 42 and 78% were male. Genotype 1a was the most common (70%) and 55% of patients were treatment naïve. The outcomes showed that 12%, 16% and 22% patients were; non-responders, breakthroughs and relapsers, respectively, while 50% of the patients reached SVR. Patients reaching SVR were aged 40 years or lower, they were less likely to have been a non-responder in prior treatments, more likely to have a non-1a genotype and a higher number had an HCV RNA of less than 600 000 IU/ml. The multivariate analysis showed that an age of 40 or lower (OR = 3.74, CI95% = 1.52-9.22), a non-1a genotype (OR = 3.71, CI 95% = 1.40-9.81) and an HCV RNA less than 600 000 IU/ml (OR = 2.52, CI 95% = 1.03-6.15) may be useful SVR predictors. CONCLUSIONS The findings of the present study showed that half of the patients reached SVR through combined peginterferon α-2a and ribavirin treatment, the majority of whom had genotype 3a and a minority had genotype 1a. In addition, an age of 40 or lower, non-1a genotype and a viral load less than 600 000 IU/ml were strong SVR predictors.

Low dose ribavirin for treatment of hepatitis C virus infected thalassemia major patients; new indications for combination therapy. HEPATITIS MONTHLY 2012; 12:372-81. [PMID: 22879826 PMCID: PMC3412553 DOI: 10.5812/hepatmon.6592] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2012] [Revised: 05/15/2012] [Accepted: 05/30/2012] [Indexed: 02/05/2023]
Abstract
BACKGROUND Treatment guidelines contraindicate ribavirin for treatment of hepatitis C virus (HCV) infection in thalassemia major patients. Nevertheless, the current evidence suggests that ribavirin might be tolerated by these patients. OBJECTIVES Despite this evidence, low dose ribavirin combination therapy has not been compared with peginterferon monotherapy in these patients so far. PATIENTS AND METHODS Two hundred eighty thalassemia patients with detectable HCV-RNA PCR (≥ 50 IU/mL) and liver histology consistent with chronic HCV infection were self-assigned to receive peginterferon alfa-2a (n = 81) monotherapy or its combination therapy with ribavirin, 600-800 mg QD, according to hemoglobin levels (n = 199). Treatment experienced patients were eligible for this study. RESULTS Sustained virological response (SVR) was significantly higher in patients who received ribavirin (51 % vs. 38 % P = 0.02). In multivariate regression, OR of ribavirin for prediction of SVR was 2.2 (95 % CI 1.24-3.91). The SVR was significantly higher in the ribavirin group in subgroups of patients with more than 24 years of age, elevated ALT, ferritin < 2006 ng/mL, previous treatment failure, genotype 1, positive history of splenectomy, fibrosis score of 0-4 HAI and viral load < 600,000 IU/mL. Treatment discontinuations due to the safety concerns were comparable between the treatment groups (6.5 and 8 %). Furthermore, transfusion intervals were almost halved in patients who received low dose ribavirin. CONCLUSIONS According to the present study, adult thalassemia patients with HCV infection can be treated successfully with low dose ribavirin. Hence, we strongly advise combination therapy in thalassemia patients with aforementioned clinical characteristics. Moreover, ribavirin does not seem to be beneficial in thalassemia patients below 18 years of age.

Abstract
CONTEXT Hepatitis C virus (HCV) infection is a public health problem. HCV alone is responsible for 90% cases of acute hepatitis among multiply transfused patients who are at risk of cirrhosis and hepatocellular carcinoma (HCC). OBJECTIVES To provide a clear picture of available data, we performed a systematic review of the epidemiological characteristics of HCV infection among patients with inherited coagulation disorders in the countries under the Eastern Mediterranean Region Office (EMRO). EVIDENCE ACQUISITION Meta-analysis was carried out on the basis of results of electronic and manual search. This analysis included studies in English, French, and Persian that met with the following criteria: (1) appropriate study design: cross-sectional, case-control, and cohort; (2) studies reporting HCV prevalence according to enzyme immune assay; (3) studies in which the sample population was enrolled from EMRO countries. According to the results of the heterogeneity tests, we used fixed-effect/random-effect model for our meta-analysis, with the "Metan" command. RESULTS We included 30 studies, most of which were from Iran. The mean age of the subjects ranged from 13 to 27.1 years. The majority of the patients were male (range, 81% to 100%). The pooled estimate of HCV infection among patients with inherited coagulation disorders was 48.07% (95% confidence interval [CI], range: 27.39-55.68) in Iran, 36.03% (95% CI, range: 4.466-67.598) in Pakistan, and 48.27% (95% CI, range: 36.12-60.43) in all the EMRO countries taken together. CONCLUSIONS In Iran and other EMRO countries, the HCV infection rate among patients with inherited coagulation disorders is high. Our study shows that there is a lack of knowledge about infections in such patients in most of the EMRO countries. It is the responsibility of health-policy makers to address this knowledge gap and provide safe and adequate treatment for patients in high-risk groups.

Abstract
BACKGROUND In 2009, 3 genome-wide association studies implicated IL28B single-nucleotide polymorphisms (SNPs) as the strongest genetic pretreatment predictor of sustained virological response (SVR) in hepatitis C infection. Recently, the American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL) included IL28B testing in their guidelines. OBJECTIVES The main aim of this study was to develop and validate a simple, rapid, and inexpensive polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for genotyping of common IL28B polymorphisms (rs12979860 and rs8099917). PATIENTS AND METHODS Two methods were developed to genotype common IL28B polymorphisms: 1) PCR-sequencing as a reference method and 2) PCR-RFLP as a rapid and inexpensive method. Both polymorphisms were genotyped in 104 Iranian hepatitis C patients by both methods simultaneously. To validate the PCR-RFLP method, the PCR-RFLP genotyping results should be 100% concordant with the PCR-sequencing results. RESULTS Genotyping of rs12979860 and rs8099917 by PCR-RFLP was concordant with PCR-sequencing in 104 (100%) individuals. The analytical sensitivity and specificity of the PCR-RFLP method for genotyping of both SNPs are 100%. Among these 104 patients with chronic hepatitis C, the frequency of the rs12979860 CC, CT and TT genotypes were 40.4%, 47.1% and 12.5% and the frequency of the rs8099917 TT, GT and GG genotypes were 59.6%, 35.6% and 4.8%, respectively. Also, three IL28B haplotypes (rs12979860-rs8099917) were found among our patients including C-T, T-G and T-T with 63.9%, 22.6% and 13.5% frequency, respectively. C-G haplotype was absent in all of our patients. CONCLUSIONS We have developed a validated, fast, and simple PCR-RFLP method for genotyping of common IL28B SNPs that is more cost-effective than sequencing.

Abstract
Aim: The aim of our study was to investigate the correlation between the presence of plus-/minus-strand HCV RNA in peripheral blood mononuclear cells (PBMCs) and serum following pegylated IFN/ribavirin therapy with response to therapy in HCV-infected patients. Methods: Forty-three HCV-infected patients who completed 48 weeks of IFN/ribavirin therapy, including 25 sustained virologic responders, 12 resistants and six relapsers, comprised the study population. Plus-/minus-strand HCV RNA was detected by reverse transcription PCR in serum and PBMCs. Results: The frequency of plus-strand HCV RNA was significantly higher in PBMC and serum samples of relapsers and resistants, and this might have important implications in clinical practice and patient management. There was no correlation between presence of plus- and minus-strand HCV RNA and genotypes, except the fact that most of the patients who had plus-strand HCV RNA in PBMCs (60%) and in serum (61.53%) belonged to genotype 1a. Conclusion: Presence of plus-strand HCV RNA in PBMCs and serum after termination of therapy is associated with viral relapse and resistance to IFN/ribavirin treatment in HCV-infected patients.
