    Hepatitis C virus (HCV) infection in Egypt is the most serious health problem. Identifying HCV-positive persons at high risk of early complications can help prioritize treatment decisions. Recently, attention has been directed to non-invasive, accurate alternatives using serum biochemical markers. The transforming growth factor β 1/interleukins pathway plays an important role in the process of cell injury and inflammation. Thus, TGF-β1 and IL-17 were assessed in serum of chronic HCV patients with correlation to hepatic inflammatory and fibrotic status. The quantitative serum levels of TGF-β1 and IL-17 were analyzed among chronic hepatitis C (CHC) patients (n=75) and normal control (NC) subjects (n=15). Disease severity in patients was assessed using the Child-Pugh scores and METAVIR. Serum levels of TGF-β1 and IL-17 were significantly increased in HCV patients compared to control group. Furthermore, the levels of TGF-β1 and Il-17 were positively correlated to serum transaminases and alpha-fetoprotein and they were negatively correlated with serum albumin and platelets. Additionally, the serum levels of TGF-β1 and Il-17 were associated with inflammation grades and stages of liver fibrosis. TGF-β1 and IL-17 may be hopeful serum biomarkers concerned in the progression of liver inflammation and fibrosis accompanying chronic HCV infection. Therefore, they could be used in the future as targets for anti-fibrotic therapy of chronic HCV to ameliorate the disease progress.

    Hepatitis C virus (HCV)-specific CD4+ and CD8+ T cells are key to successful viral clearance in HCV disease. Accumulation of exhausted HCV-specific T cells during chronic infection results in considerable loss of protective functional immune responses. The role of T-cell exhaustion in chronic HCV disease remains poorly understood. Here, we studied the frequency of HCV peptide-stimulated T cells expressing negative immune checkpoints (PD-1, CTLA-4, TRAIL, TIM-3 and BTLA) by flow cytometry, and measured the levels of Th1/Th2/Th17 cytokines secreted by T cells by a commercial Multi-Analyte ELISArray™ following in vitro stimulation of T cells using HCV peptides and phytohemagglutinin (PHA). HCV peptide-stimulated CD4+ and CD8+ T cells of chronic HCV (CHC) patients showed significant increase of CTLA-4. Furthermore, HCV peptide-stimulated CD4+ T cells of CHC patients also displayed relatively higher levels of PD-1 and TRAIL, whereas TIM-3 was up-regulated on HCV peptide-stimulated CD8+ T cells. Whereas the levels of IL-10 and TGF-β1 were significantly increased, the levels of pro-inflammatory cytokines IL-2, TNF-α, IL-17A and IL-6 were markedly decreased in the T cell cultures of CHC patients. Chronic HCV infection results in functional exhaustion of CD4+ and CD8+ T cells likely contributing to viral persistence.

    BACKGROUND/AIMS: CYP3A4 is the major cytochrome in humans which shows reduced activity in chronic liver disease as well as in hepatic cirrhosis. The detection of this polymorphism may give an indication on the prognosis of patients having chronic viral hepatitis with superimposed hepatitis A infection. The aim of this study is to correlate the seroprevalence of anti-HAV antibodies in chronic liver disease patients having CYP3A4*18 polymorphisms.

    METHODOLOGY: This is a prospective study where patients (n=119) blood was tested for anti-HAVIgG and CYP3A4*18 polymorphism.

    RESULTS: The overall anti-HAV seroprevalence was 88.2%. The etiology of CLD was hepatitis B in 96 patients (80.7%) and hepatitis C in 23 patients (19.3%). There was a significant increase in the age of the prevalence of this disease after 30 years of age (p=0.008). CYP3A4*18 polymorphism was detected in 3 (2.5%) of the patients with chronic liver disease. However, there was no significant association between CP3A4*18 mutation and anti-HAV serology.

    CONCLUSIONS: Age was the most important factor in determining anti-HAV positivity. It is concluded that CYP3A4*18 genetic polymorphism does not play a main role in influencing the seroprevalence of anti-hepatitis A among chronic viral hepatitis B and C liver disease patients.

    The aim of this study was to determine if knowledge of both the serum HCV RNA and serum anti core IgM antibody status enabled one to predict the histological severity in chronic hepatitis C. We studied 45 female patients with chronic hepatitis C infection. The presence or absence of IgM antibodies to HCV and HCV RNA by PCR in each patient's serum was determined. Liver biopsies performed were scored according to a modified Desmet's histological activity index. Negative HCV RNA patients had least histological change. HCV RNA positive patients who were also IgM antibody positive had lower scores than their IgM negative counterparts. The grade of histological severity is more accurately predictable from knowledge of both the HCV RNA and IgM anti HCV status of the patient.

    Data on markers of hepatitis C virus (HCV) disease in HIV-HCV-coinfected patients in resource-limited settings are scarce. We assessed HCV RNA, HCV genotype (GT), IL28B GT and liver fibrosis (FibroScan® ) in 480 HIV-infected patients with positive HCV antibody in four HIV treatment centres in South-East Asia. We enrolled 165 (34.4%) patients in Jakarta, 158 (32.9%) in Bangkok, 110 (22.9%) in Hanoi and 47 (9.8%) in Kuala Lumpur. Overall, 426 (88.8%) were male, the median (IQR) age was 38.1 (34.7-42.5) years, 365 (76.0%) reported HCV exposure through injecting drug use, and 453 (94.4%) were on combination antiretroviral therapy. The median (IQR) CD4 count was 446 (325-614) cells/mm3 and 208 (94.1%) of 221 patients tested had HIV-1 RNA <400 copies/mL. A total of 412 (85.8%) had detectable HCV RNA, at a median (IQR) of 6.2 (5.4-6.6) log10 IU/mL. Among 380 patients with HCV GT, 223 (58.7%) had GT1, 97 (25.5%) had GT3, 43 (11.3%) had GT6, eight (2.1%) had GT4, two (0.5%) had GT2, and seven (1.8%) had indeterminate GT. Of 222 patients with IL28B testing, 189 (85.1%) had rs12979860 CC genotype, and 199 (89.6%) had rs8099917 TT genotype. Of 380 patients with FibroScan® , 143 (37.6%) had no/mild liver fibrosis (F0-F1), 83 (21.8%) had moderate fibrosis (F2), 74 (19.5%) had severe fibrosis (F3), and 79 (20.8%) had cirrhosis (F4). One patient (0.3%) had FibroScan® failure. In conclusion, a high proportion of HIV-HCV-coinfected patients had chronic HCV infection. HCV GT1 was predominant, and 62% of patients had liver disease warranting prompt treatment (≥F2).

    The neurological manifestations of chronic hepatitis C is most often a peripheral sensory neuropathy characterised by numbness, burning and sensation of "pins and needles". Peripheral motor neuropathy, mononeuropathy, mononeuropathy multiplex and transverse myelitis also occur. Ischemic stroke and transient cerebral ischemia have also been reported. Anterior ischemic optic neuropathy is seen, often following interferon therapy. We report an exceptional case of neuromyelitis optica in chronic hepatitis C infection in the absence of interferon therapy.

    Persistent hepatitis C virus (HCV) infection appears to trigger the onset of immune exhaustion to potentially assist viral persistence in the host, eventually leading to hepatocellular carcinoma. The role of HCV on the spontaneous expression of markers suggestive of immune exhaustion and spontaneous apoptosis in immune cells of chronic HCV (CHC) disease largely remain elusive. We investigated the peripheral blood mononuclear cells of CHC patients to determine the spontaneous recruitment of cellular reactive oxygen species (cROS), immunoregulatory and exhaustion markers relative to healthy controls. Using a commercial QuantiGenePlex(®) 2.0 assay, we determined the spontaneous expression profile of 80 different pro- and anti-apoptotic genes in persistent HCV disease. Onset of spontaneous apoptosis significantly correlated with the up-regulation of cROS, indoleamine 2,3-dioxygenase (IDO), cyclooxygenase-2/prostaglandin H synthase (COX-2/PGHS), Foxp3, Dtx1, Blimp1, Lag3 and Cd160. Besides, spontaneous differential surface protein expression suggestive of T cell inhibition viz., TRAIL, TIM-3, PD-1 and BTLA on CD4+ and CD8+ T cells, and CTLA-4 on CD4+ T cells was also evident. Increased up-regulation of Tnf, Tp73, Casp14, Tnfrsf11b, Bik and Birc8 was observed, whereas FasLG, Fas, Ripk2, Casp3, Dapk1, Tnfrsf21, and Cflar were moderately up-regulated in HCV-infected subjects. Our observation suggests the spontaneous onset of apoptosis signaling and T cell exhaustion in chronic HCV disease.

    An analysis of 105 consecutive patients with chronic hepatitis C at the gastroenterology outpatient's clinic in Hospital Kuala Lumpur was performed. The clinical, laboratory and virological data was prospectively recorded in the case notes and comprised of data on patient characteristics, risk factors, clinical features, laboratory features, virology screen and management. Chronic Hepatitis C cases accounted for 2.1% of the total number of cases seen at this clinic during the entire period. There were 78 (74%) males and 27 (26%) females. The ethnic breakdown consisted of Chinese (44.2%), Malays (39.4%), Indians (15.4%) and others (1%). There was higher male preponderance in all the ethnic groups. The main mode of transmission was blood transfusion comprising 51 patients (48.8%). A total of 35.2% of cases underwent treatment, of which a proportion had interferon monotherapy for 6 or 12 months and a subsequent group of naïve patients and non-responders underwent combination therapy with interferon and ribavarin.

    BACKGROUND & AIMS: Affordable point-of-care (POC) tests for hepatitis C (HCV) viraemia are needed to improve access to treatment in low and middle income countries (LMICs). Our aims were to determine the target limit of detection (LOD) necessary to diagnose the majority of persons with HCV eligible for treatment, and identify characteristics associated with low-level viraemia (LLV) (defined as the lowest 3% of the distribution of HCV RNA) to understand those at risk of being mis-diagnosed.

    METHODS: We established a multi-country cross-sectional dataset of first available quantitative HCV RNA linked to demographic and clinical data. We excluded individuals on HCV treatment. We analyzed the distribution of HCV RNA and determined critical thresholds for detection of HCV viraemia. We then performed logistic regression to evaluate factors associated with LLV, and derived relative sensitivities for significant covariates.

    RESULTS: The dataset included 66,640 individuals with HCV viraemia from Georgia (44.4%), Canada (40.9%), India (8.1%), Cambodia (2.6%), Egypt (1.6%), Pakistan (1.3%), Cameroon (0.4%), Indonesia (0.2%), Thailand (0.2%), Vietnam (0.1%), Malaysia (0.05%), and Mozambique (0.02%). The 97% LOD was 1,318 IU/mL (95% CI 1298.4, 1322.3). Factors associated with LLV were younger age 18-30 vs. 51-64 years (OR 2.56 95% CI 2.19, 2.99), female vs. male sex (OR 1.32, 95% CI 1.18, 1.49), and advanced fibrosis stage F4 vs. F0-1 (OR 1.44, 95%CI 1.21, 1.69). Only the younger age group had a decreased relative sensitivity below 95% at 93.3%.

    CONCLUSIONS: In this global dataset, a test with an LOD of 1,318 IU/mL would identify 97% of viraemic HCV infections among almost all populations. This LOD will help guide manufacturers in the development of affordable POC diagnostics to expand HCV testing and linkage to care in LMICs.

    LAY SUMMARY: We created and analyzed a dataset from 12 countries with 66,640 participants with chronic hepatitis C virus infection. We determined that about 97% of those with viraemic infection had 1300 International Units/mL or more of circulating virus at the time of diagnosis. While current diagnostic tests can detect as little as 12 International Units/mL of virus, our findings suggest that increasing the level of detection closer to 1300 would maintain good test accuracy and will likely allow for more affordable portable tests to be developed for use in low and middle income countries.

    Introduction: Diabetes-associated autoantibodies (DAA) is the hallmark of T1DM and LADA which are frequently tested in young diabetes patients. It was noted that up to 10-15% of patients with initial diagnosis of T2DM also exhibit DAA. Regardless of the classification, the presence of DAA suggests an underlying islet autoimmunity which lead to progressive pancreatic β-cell failure. There is limited data reported on DAA in young diabetes patients in Malaysia. This study aims to determine the frequency of DAA positivity and its association with demographic and clinical characteristics among this cohort. Methods: A retrospective study using secondary data obtained from Al- lergy and Immunology Research Centre, Institute for Medical Research, Malaysia. This study included 194 diabetes patients who were diagnosed before the age of 40 years old and tested for GADA, ICA, IA2A and IAA. Results: From 194 patients, 91 (46.9%) were positive for least one of the following DAA: ICA (79, 40.7%), GADA (61, 31.4%), IA2A (37, 19.1%) and IAA (9, 4.6%). Multiple positivity was higher (73.6%) compared to single positivity. Highest com- bination of double positivity was ICA+GADA (54, 59.3%) and triple positivity was ICA+GADA+IA2A (25, 27.5%). Simultaneous positivity of four autoantibodies was seen in only one (1.1%) patient. ICA, GADA and IA2A were asso- ciated with age group and ethnicity (all p < 0.001). Only IA2A was associated with gender (p = 0.012). Conclusions: GADA, ICA ad IA2A are more significant in young Malaysian diabetes patients. IAA has a very low frequency in this studied population.

    BACKGROUND: In low-income and middle-income countries, affordable direct-acting antivirals are urgently needed to treat hepatitis C virus (HCV) infection. The combination of ravidasvir, a pangenotypic non-structural protein 5A (NS5A) inhibitor, and sofosbuvir has shown efficacy and safety in patients with chronic HCV genotype 4 infection. STORM-C-1 trial aimed to assess the efficacy and safety of ravidasvir plus sofosbuvir in a diverse population of adults chronically infected with HCV.

    METHODS: STORM-C-1 is a two-stage, open-label, phase 2/3 single-arm clinical trial in six public academic and non-academic centres in Malaysia and four public academic and non-academic centres in Thailand. Patients with HCV with compensated cirrhosis (Metavir F4 and Child-Turcotte-Pugh class A) or without cirrhosis (Metavir F0-3) aged 18-69 years were eligible to participate, regardless of HCV genotype, HIV infection status, previous interferon-based HCV treatment, or source of HCV infection. Once daily ravidasvir (200 mg) and sofosbuvir (400 mg) were prescribed for 12 weeks for patients without cirrhosis and for 24 weeks for those with cirrhosis. The primary endpoint was sustained virological response at 12 weeks after treatment (SVR12; defined as HCV RNA <12 IU/mL in Thailand and HCV RNA <15 IU/mL in Malaysia at 12 weeks after the end of treatment). This trial is registered with ClinicalTrials.gov, number NCT02961426, and the National Medical Research Register of Malaysia, NMRR-16-747-29183.

    FINDINGS: Between Sept 14, 2016, and June 5, 2017, 301 patients were enrolled in stage one of STORM-C-1. 98 (33%) patients had genotype 1a infection, 27 (9%) had genotype 1b infection, two (1%) had genotype 2 infection, 158 (52%) had genotype 3 infection, and 16 (5%) had genotype 6 infection. 81 (27%) patients had compensated cirrhosis, 90 (30%) had HIV co-infection, and 99 (33%) had received previous interferon-based treatment. The most common treatment-emergent adverse events were pyrexia (35 [12%]), cough (26 [9%]), upper respiratory tract infection (23 [8%]), and headache (20 [7%]). There were no deaths or treatment discontinuations due to serious adverse events related to study drugs. Of the 300 patients included in the full analysis set, 291 (97%; 95% CI 94-99) had SVR12. Of note, SVR12 was reported in 78 (96%) of 81 patients with cirrhosis and 153 (97%) of 158 patients with genotype 3 infection, including 51 (96%) of 53 patients with cirrhosis. There was no difference in SVR12 rates by HIV co-infection or previous interferon treatment.

    INTERPRETATION: In this first stage, ravidasvir plus sofosbuvir was effective and well tolerated in this diverse adult population of patients with chronic HCV infection. Ravidasvir plus sofosbuvir has the potential to provide an additional affordable, simple, and efficacious public health tool for large-scale implementation to eliminate HCV as a cause of morbidity and mortality.

    Eight weeks duration of ledipasvir/sofosbuvir (LDV/SOF) can be considered in genotype 1 hepatitis C virus-infected patients who are treatment-naive, do not have cirrhosis, and have a pretreatment viral load <6,000,000 IU/mL. The effectiveness of this regimen, however, has not been fully confirmed by real-world experience. Using data from real-world cohorts, we aimed to determine the effectiveness of 8 weeks of LDV/SOF treatment, examine variables associated with relapse after treatment with this regimen, and compare the effectiveness of 8 weeks and 12 weeks of LDV/SOF treatment. To evaluate the effectiveness of 8 weeks of therapy and characteristics associated with relapse, we used individual patient data from the IFI (Institut für Interdisziplinäre Medizin), Burman's Pharmacy, and Kaiser Permanente Southern California. All patients had fibrosis staging assessed with biopsy, transient elastography, or serum biomarkers. We also performed a systematic review and meta-analysis of six additional real-world cohorts, to compare effectiveness of 8 weeks to 12 weeks duration. In our pooled data analysis, 634 patients were treated for 8 weeks with LDV/SOF, of whom all had outcomes of cure or relapse without loss to follow-up. Per protocol rates of sustained virologic response at 12 weeks were 98.1% (622/634) in the full cohort and 97.9% (571/583) among treatment-eligible patients. Exact logistic regression revealed no specific patient characteristics associated with relapse. Our meta-analysis of six additional real-world cohorts, comprised of 5,637 patients, demonstrated similar risk for relapse between 8 weeks and 12 weeks of LDV/SOF (relative risk = 0.99, 95% confidence interval 0.98-1.00).

    CONCLUSION: An 8-week duration of treatment with LDV/SOF is highly effective in properly selected patients; greater use of this regimen is recommended. (Hepatology 2017;65:1094-1103).

    There is a paucity of information on chronic hepatitis C (CHC) patients treated with direct antiviral agents (DAAs) in Asia. We invited Asia-Pacific physicians to collate databases of patients enrolled for CHC treatment, recording baseline clinical, virologic and biochemical characteristics, sustained virologic response at week 12 (SVR12) and virologic failure. SVR12 outcome was based on intention to treat (ITT). Multivariate analysis was used to assess independent risk factors for SVR12 using SPSS version 20. A total of 2171 patients from India (n = 977), Myanmar (n = 552), Pakistan (n = 406), Thailand (n = 139), Singapore (n = 72) and Malaysia (n = 25) were collected. At baseline, mean age was 49 years, 50.2% were males, and 41.8% had cirrhosis. Overall, SVR12 was 89.5% and by genotype (GT) based on ITT and treatment completion, respectively, was 91% and 92% for GT1, 100% and 100% for GT2, 91% and 97% for GT3, 64% and 95% for GT4, 87% and 87% for GT6 and 79% and 91% for GT untested. Patients with cirrhosis had SVR12 of 85% vs 93% for noncirrhosis (P < 0.001) (RR 2.1, 95% CI 1.4-3.1, P = 0.0002). Patients with GT1 and GT3 treated with sofosbuvir/ribavirin (SR) had 88% and 89% SVR12, respectively, but those GT6 treated with sofosbuvir/ledipasvir (SL) had only 77.6% SVR12. Multivariate analysis showed absence of cirrhosis was associated with higher SVR12 (OR 2.0, 95% CI 1.3-3.1, P = 0.002). In conclusion, patients with GT1 and GT3 with/without cirrhosis had surprisingly high efficacy using SR, suggesting that Asians may respond better to some DAAs. However, poor GT6 response to SL suggests this regimen is suboptimal for this genotype.

    180 million people are affected by chronic Hepatitis C Virus infection globally and more than 50 million in South East Asia. Combination of Interferon and Ribavirin is the current anti-HCV therapy in practice and is associated with certain hematologic adverse effects. In this concurrent observational study the incidence rate of major hematologic adverse effects and efficacy outcomes of Interferon and Ribavirin combination therapy was evaluated in 288 chronic hepatitis C patients at Lahore General Hospital. Levels of Hb, TLC, and Platelets counts were monitored for hematologic adverse effects monitoring, whereas, ALT, AST and bilirubin levels were monitored for efficacy. PCR was done at week 4, 12 &36 for therapeutic success evaluation. A significant reduction in Hb levels (p<0.05) was observed after week 4, 8 and 12 of therapy. Frequency of anemia increased in both genders with body weight <65kg and platelet count <150,000/mm(3). End Treatment Response (ETR) was achieved in 64.5%. Anemia was the major side effect of the combination therapy particularly in the males. Higher ETR was observed in patients who achieved RVR and were <50 years of age.

    Hepatitis C is a liver disease caused by the hepatitis C virus: the virus can cause both acute and chronic hepatitis infection. Patients with chronic hepatitis C virus (HCV) infection appear to have an excellent chance of responding to 6 months of standard therapy with interferon (IFN) and frequently develop systemic iron overload, which exacerbates morbidity. The iron excess in hepatitis C may be due to hereditary hemochromatosis, hematologic diseases, multiple transfusions, porphyria cutanea tarda and chronic alcohol abuse. Different mechanisms proposed to explain the relation between HCV infection and hepatic iron overload. Some revealed that hepatic iron accumulation results from release of iron from damaged liver cells. Consumption of coffee, tea also reduces iron absorption and thereby decrease iron overload in Liver and thereby reduces the oxidative stress of iron overload in liver. The global scenario of this problem has been discussed in the article.
