Sofosbuvir/Velpatasvir/Voxilaprevir for Hepatitis C Virus Retreatment in Difficult-to-treat Patients: A Real-life Observational Study from India. J Clin Exp Hepatol 2024; 14:101314. [PMID: 38261859 PMCID: PMC10792231 DOI: 10.1016/j.jceh.2023.101314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 12/03/2023] [Indexed: 01/25/2024] Open
Abstract
Background and aim Hepatitis C virus (HCV) treatment fails to achieve sustained virological response at 12 weeks (SVR12) in 5-10 % and requires retreatment with second-line drugs. We report our experience of sofosbuvir/velpatasvir/voxilaprevir use for HCV retreatment in a small cohort of difficult-to-treat Indian patients. Methods We reviewed our HCV databases to identify the patients who had failed to achieve SVR12 after treatment with sofosbuvir in combination with either daclatasvir, ledipasvir, or velpatasvir with/without ribavirin on one or more occasions. Participants were excluded if they had (i) decompensated cirrhosis, (ii) HIV coinfection or (iii) chronic kidney disease, or (iv) prior organ transplantation. All the participants were treated with sofosbuvir/velpatasvir/voxilaprevir plus ribavirin for 12 weeks. Treatment outcome was categorized as successful or failure if HCV RNA was undetectable or detectable at SVR12, respectively. Results Fifteen patients (male 67 %; genotype-3 80 %) were included in the analysis. Ten (67 %) had cirrhosis. Five, eight, and two participants had previously failed one, two, and three courses of pegylated-interferon free, sofosbuvir containing direct acting antiviral (DAA) regimens respectively. Fourteen participants had failed to at least one course of the sofosbuvir/velpatasvir combination. Fourteen patients achieved SVR12, and one patient was lost to follow-up. Treatment was successful in 100 % and 93.3 % of per-protocol (PP) and intention to treat (ITT) analyses, respectively. Conclusion Sofosbuvir/velpatasvir/voxilaprevir combination is an effective second-line therapy in India for difficult-to-treat HCV patients.

Abstract
Background and Aims Sofosbuvir (S), daclatasvir (D), ledipasvir, or velpatasvir (V) containing first-line hepatitis C virus (HCV) treatment regimens fail to cure viremia in 5-10%. We report our experience of HCV retreatment using these first-line drugs, in a setting where second-line anti-HCV drugs are not available. Methods Adults, who had relapsed after first complete course of a sofosbuvir-containing first-line, pegylated interferon free, anti-HCV treatment regimen with or without ribavirin (Riba) were included. Retreatment regimen, tailored to the failed anti-HCV regimen, was based on principle of using first-line drugs for 24 weeks with ribavirin and swapping between pangenotypic and genotype-specific regimens. Retreatment outcome was categorized as successful (achieved undetectable HCV RNA at the end of treatment [ETR] and sustained viral response at week 12 [SVR12]), non-responder (failed to achieve ETR), or relapse (achieved ETR but not achieved SVR12). Results Twelve patients (9 male; 7 cirrhosis; all genotype 3) who had relapsed to prior anti-HCV treatment (4 SD12, 4 SD24, 1 SDRiba12, 1 SDRiba24, 2 SV12) were included. Following retreatment (2 SDRiba24, 10 SVRiba24), all achieved ETR but only 9 (75%) achieved SVR12. Two among three, in whom retreatment failed, achieved SVR12 following another course of sofosbuvir/velpatasvir/ribavirin for 24 weeks. Overall, 11/12 (92%) patients achieved SVR12 following retreatment with the first-line anti-HCV drugs. Conclusion HCV retreatment could be a treatment option if second-line anti-HCV drugs are not available. Successful retreatment could be achieved, in a large proportion, with the use of first-line drugs for 24 weeks with ribavirin and swapping of pangenotypic/genotype-specific regimens (NCT03483987).

Sofosbuvir and Velpatasvir combination is safe and effective in treating chronic hepatitis C in end-stage renal disease on maintenance haemodialysis. Liver Int 2021; 41:705-709. [PMID: 33025685 DOI: 10.1111/liv.14685] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/05/2020] [Accepted: 09/21/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND & AIMS There is emerging data on the use of Sofosbuvir-based directly acting antiviral (DAA) drug regimens in chronic hepatitis C (CHC) patients with end-stage renal disease (ESRD) on maintenance haemodialysis (MHD). We evaluated the safety and efficacy of Sofosbuvir plus Velpatasvir fixed-dose combination in CHC patients with ESRD on MHD. METHODS Fifty-one CHC patients with ESRD on MHD were included in a real-life prospective study. All patients irrespective of genotype; presence of cirrhosis; treatment naive or experienced status were treated with full-dose Sofosbuvir (400 mg) plus Velpatasvir (100 mg) fixed-dosed combination given daily for 12 weeks. The efficacy was assessed by the sustained virological response (SVR12) with negative HCV RNA 12 weeks after the end of treatment (ETR). Side effects if any were recorded in all patients. RESULTS The median HCV RNA level in 51 CHC patients [Males 41 (80.4%), mean age 42.8 ± 14.6 years] was 2.0 × 106 IU/mL. HCV genotype was available in 19 patients with predominant genotype 1 in 15 (79%) patients. Ten (19.6%) patients had evidence of cirrhosis (defined as LSM ≥ 12.5 kPa on Transient Elastography), and 8 (15.6%) patients were treatment experienced. Testing for ETR was done in 36 patients and all 36 (100%) patients achieved ETR, and 49 patients (96%) achieved SVR 12. All 51 patients tolerated the Sofosbuvir + Velpatasvir combination, with none of the patients reporting any serious adverse event. CONCLUSION Sofosbuvir plus Velpatasvir fixed-dose combination is safe and effective in treating CHC in patients with ESRD on MHD.

A new model to predict response to direct-acting antiviral therapy in decompensated cirrhotics due to hepatitis C virus. Clin Exp Hepatol 2020; 6:253-262. [PMID: 33145432 PMCID: PMC7592091 DOI: 10.5114/ceh.2020.99525] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Accepted: 06/19/2020] [Indexed: 02/06/2023] Open
Abstract
AIM of the study: Decompensated hepatitis C virus (HCV) cirrhosis is a difficult to treat cohort, and there is no gold standard predictor of response to direct-acting antiviral (DAA) therapy. We conducted this study to look for factors responsible for improvement in post-therapy status, i.e. attainment of Child-Turcotte-Pugh (CTP) class A from B or C, and devise a new model to predict post-therapy response. MATERIAL and methods: Prospective analysis of data from decompensated HCV cirrhotics was done and association of each parameter with patient outcomes at 36 weeks after treatment was assessed. RESULTS 34 patients (54.8%) attained CTP class A after treatment. Factors that were independently associated with disease outcome included albumin (odds ratio [OR] = 4.84, 95% confidence interval [CI]: 1.43-20.15, p = 0.018), alanine transaminase (ALT) (OR = 1.02, 95% CI: 1-1.04, p = 0.049), bilirubin (OR = 0.41, 95% CI: 0.2-0.75, p = 0.007) and estimated glomerular filtration rate (eGFR) (OR = 1.03, 95% CI: 1.0-1.06, p = 0.045). On multivariate analysis, bilirubin was significantly associated with treatment outcome (OR = 0.28, 95% CI: 0.1-0.64, p = 0.006). A composite model was devised using demographic, biochemical, and clinical features, which has sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 67.86%, 79.41%, 73.08%, 75%, and 73.63% respectively in predicting response to therapy. Only 7.6% of patients with a Model for End-Stage Liver Disease (MELD) score > 15 and none of the patients with CTP class C met the primary end-point of our study. CONCLUSIONS 55% of our cohort met the primary end-point at 36 weeks. Patients with CTP class C and a MELD score > 15 should be referred for liver transplantation followed by DAA therapy. Our model was good at predicting improvement in post-therapy liver function.

Abstract
The availability of directly acting antivirals (DAA) has revolutionised the management of hepatitis C in low- and middle-income countries such as India. We aimed to determine the spectrum of hepatitis C-related liver disease and the response to treatment using generic DAAs, using retrospective data collected from a cohort of adult patients. Patients with hepatocellular carcinoma, co-infection with hepatitis B, HIV and those with incomplete data were excluded. A sustained virological response was documented in 101/106 (95.3%) cases; we therefore conclude that DAAs are highly effective in the management of hepatitis C infection across a wide spectrum of clinical presentations.

Abstract
Context The Indian government is dispensing newer direct-acting antiviral (DAA) drugs, which may have impact on hepatitis C virus (HCV) patients' quality of life (QoL). Aims To evaluate different DAA regimens and impact on QoL in terms of quality-adjusted life year (QALY) in HCV patients and to measure cost-effectiveness. Methods This prospective, observational study was carried out on patients who were diagnosed with HCV. Recruited patients were followed up until 12-24 weeks. Patients were recruited following the selection criteria. Along with demographic and drug details, the regimens used were analyzed and evaluated for cost minimization, cost-effectiveness, and cost-utility analysis. For health quality check, the Chronic Liver Disease questionnaire (CLDQ) was used which was also used for QALY assessment. Data were entered into MS Excel 2016. Difference in between the regimens for total cost was done using unpaired t-test and ANOVA test using SPSS 25.0. Overall cost-effectiveness, cost minimization, cost utility and cost of illness analysis was also calculated. P < 0.05 was considered statistically significant. Results A total of 31 patients were enrolled. A total of five drugs, namely, sofosbuvir, daclatasvir, ribavirin, velpatasvir, and ledipasvir were widely used. Sofosbuvir was most common (46.25%)component of drug combination in our study. A total of five types of regimen were used according to the genotype of patients. With 44,260.13 ± 15,884.92 INR of the total drug cost, 70.97% of patients spent around 30,000-40,000 INR for the whole pharmacotherapy. The total indirect cost was 2768.39 ± 3916.13 INR with the total direct cost of 48,660.90 ± 15,356.39 INR. The total cost including direct as well as indirect cost spent during 6-month therapy by 61.29% of patients was 40,000-50,000 INR. Based on the CLDQ score, QoL was 64.1 ± 25. Regimen 2 (sofosbuvir + velpatasavir) stood out with the lowest cost. Regimen 5 (ribavirin [200 mg] + sofosbuvir [400 mg] + velpatasvir [100 mg]) was found to be the most cost-effective. Considering 1 life year with good health after treatment, QALY was 0.31. Conclusions Ribavirin (200 mg) + sofosbuvir (400 mg) + velpatasvir (100 mg) was found to be the cost-effective and cost-saving regimen among DAAs.

Abstract
AIM Sofosbuvir is a key agent for HCV treatment. It is not recommended for patients with chronic kidney disease (CKD) and estimated glomerular filtration rate (eGFR) <30 mL/min. We report real-life experience of treating a cohort of CKD patients with eGFR <30 mL/min using daclatasvir and half-daily dose of sofosbuvir. METHODS Adults patients who (i) had eGFR<30 mL/min and detectable HCV RNA and (ii) were treated with interferon and ribavirin free, DAA based regimens were included. All patients were treated with daily doses of daclatasvir 60 mg and sofosbuvir 200 mg. The planned duration of treatment was 12 weeks, except for 24 weeks in those with either clinical evidence of cirrhosis or on immunosuppressive drugs. The end-points of the study were: (i) 12 weeks of follow-up after treatment completion, (ii) treatment discontinuation, or (iii) death or loss to follow-up. RESULTS Thirty-six (88%) among 41 included patients (median [range] age: 48 [19-75] years; 25 [61%] male; genotype 1/3/4 were 17/ 22/2; cirrhosis 5) completed the treatment, two discontinued and three died during treatment. On an intention-to-treat basis, HCV RNA were undetectable at 4 weeks of treatment, treatment completion and after 12 weeks of follow-up in 40/41 (97.6%), 37/41 (90.2%) and 37/41 (90.2%), respectively. None of the patients had a relapse. CONCLUSIONS Daclatasvir and half-daily dose of sofosbuvir was effective against genotype 1 and 3 HCV infection in patients with eGFR <30 mL/min. This combination could be a pangenotypic treatment option for such patients.

Cost-effectiveness and budgetary impact of HCV treatment with direct-acting antivirals in India including the risk of reinfection. PLoS One 2019; 14:e0217964. [PMID: 31170246 PMCID: PMC6553784 DOI: 10.1371/journal.pone.0217964] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 05/22/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND HCV direct-acting antivirals (DAAs) are produced in India at low cost. However, concerns surrounding reinfection and budgetary impact limit treatment scale-up in India. We evaluate the cost-effectiveness and budgetary impact of HCV treatment in India, including reinfection. METHODS A closed cohort Markov model of HCV disease progression, treatment, and reinfection was parameterized. We compared treatment by fibrosis stage (F2-F4 or F0-F4) to no treatment from a health care payer perspective. Costs (2017 USD$, based on India-specific data) and health utilities (in quality-adjusted life years, QALYs) were attached to each health state. We assumed DAAs with 90% sustained viral response at $900/treatment and 1%/year reinfection, varied in the sensitivity analysis from 0.1-15%. We deemed the intervention cost-effective if the incremental cost-effectiveness ratio (ICER) fell below India's per capita GDP ($1,709). We assessed the budgetary impact of treating all diagnosed individuals. RESULTS HCV treatment for diagnosed F2-F4 individuals was cost-saving (net costs -$2,881 and net QALYs 3.18/person treated; negative ICER) compared to no treatment. HCV treatment remained cost-saving with reinfection rates of 15%/year. Treating all diagnosed individuals was likely cost-effective compared to delay until F2 (mean ICER $1,586/QALY gained, 67% of simulations falling under the $1,709 threshold) with 1%/year reinfection. For all scenarios, annual retesting for reinfection was more cost-effective than the current policy (one-time retest). Treating all diagnosed individuals and reinfections results in net costs of $445-1,334 million over 5 years (<0.25% of total health care expenditure over 5 years), and cost-savings within 14 years. CONCLUSIONS HCV treatment was highly cost-effective in India, despite reinfection. Annual retesting for reinfection was cost-effective, supporting a policy change towards more frequent retesting. A comprehensive HCV treatment scale-up plan is warranted in India.

Abstract
Treatment of Hepatitis C virus (HCV) in patients with severe renal insufficiency is cumbersome as sofosbuvir is mainly excreted by the kidneys. There is paucity of data on the use of sofosbuvir and NS5A inhibitors in these patients. We hereby report our experience of treating chronic hepatitis C in patients with severe renal insufficiency with full dose sofosbuvir and NS5A inhibitors. Forty-seven patients with severe renal insufficiency (on dialysis n = 39, predialysis n = 8) with HCV infection were treated between December 2015-August 2017 with full dose sofosbuvir with ledipasvir or daclatasvir for 12/24 weeks depending on the genotype and the presence or absence of cirrhosis. The distribution of HCV genotype was genotype 1 in 32 (68.1%), genotype 3 in 13 (27.7%) and 4 in 2 (4.3%) patients. Among 12 (25.5%) patients with cirrhosis, 7 (14.9%) were decompensated with ascites. All patients had end of treatment response, and sustained viral response at 12 weeks was achieved in 45 (95.7%) patients. There was significant improvement in liver stiffness at 3 months after treatment (8.8 (3.8-42) to 7.1 (3.3-24.1) kPa; (P = 0.047)). There was no change in haemoglobin and eGFR with treatment in predialysis group (haemoglobin- 10.2 ± 1.5 g/dL vs 9.6 ± 1.3 g/dL, P = 0.44; eGFR- 19.8 ± 9.4 mL/min vs 17.9 ± 8.5 mL/min, P = 0.67). Therapy was very well accepted. Full dose sofosbuvir with NS5A inhibitors is a well tolerated and effective therapy for HCV infection in severe renal insufficiency.

[PMID: 30147941 PMCID: PMC6104766 DOI: 10.1136/bmjgast-2018-000209] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2018] [Revised: 05/10/2018] [Accepted: 05/19/2018] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Genotype 3 (GT3) is a common chronic hepatitis C (CHC) genotype in Asia. Direct-acting antiviral (DAA) regimens have high cure rates, but real-world results are limited for Asia. AIM To determine the real-world effectiveness of DAAs for patients with CHC GT3 in Asia. METHODS A systematic search was performed in PubMed (including MEDLINE), Embase, and selected international meeting abstract repositories. Eligible studies were postmarketing observational studies from Asia with the primary outcome of sustained virological response 12 weeks after completion of treatment (SVR12). RESULTS A total of 15 studies with 4230 patients yielded a pooled SVR12 of 92.7%. High heterogeneity (I2=93.2%, P<0.0001) was noted. In subgroup analyses, patients with cirrhosis had 10.9% lower SVR12 than non-cirrhotic patients (88.6% vs 98.9%; P<0.0001) and contributed 69.5% of the heterogeneity. Prior treatment failure did not reduce the pooled SVR12 (treatment-naïve: 94.6%, 95% CI 91.3% to 96.7% vs treatment-experienced: 94.0%, 95% CI 77.5% to 98.6%; P=0.89). Twenty-four weeks of sofosbuvir+ribavirin dual therapy was the most commonly used regimen which led to similar SVR12 (OR=1.1, P=0.73) but lower adverse event rate than 12 weeks of sofosbuvir+ribavirin+pegylated interferon triple therapy. CONCLUSION Sofosbuvir+ribavirin for 24 weeks is the most widely used and generally well-tolerated DAA therapy in Asia. However, its effectiveness is not optimal in GT3 patients with cirrhosis.

Abstract
BACKGROUND Hepatitis C infection is known to increase the morbidity in patients with end stage renal disease (ESRD). Interferon based treatment is poorly tolerated and has limited cure rates in these patients. In limited available data, sofosbuvir based regimens have been shown to have favorable outcomes in these patients. METHODS We treated 7 patients with ESRD on hemodialysis, 6 with chronic hepatitis C and one with acute hepatitis C. Two of them were cirrhotic of which one was decompensated. All patients were treated with sofosbuvir 200 mg with daclatasvir 60 mg or ribavirin 200 mg once daily. Patients with evidence of cirrhosis were treated for 24 weeks, others were treated for 12 weeks. HCV RNA quantitative PCR was monitored at weeks 2, 4, 12, end of therapy and after 12 weeks of end of treatment (SVR12). RESULTS The study cohort included five males and two females, aged (48.4 ± 14.5 years). Four patients had genotype 1 and three had genotype 3. One patient was treated with sofosbuvir and ribavirin while others were treated with sofosbuvir and daclatasvir. One patient died of unrelated cause during the therapy. One patient who received sofosbuvir and daclatasvir, could not complete the therapy beyond 20 weeks because she developed recurrent hypoglycemia, which improved after stopping the therapy, all the other patients had SVR 12. There was no change in Hb levels or erythropoietin requirement in the patients receiving sofosbuvir and daclatasvir. CONCLUSION Our data suggest that sofosbuvir based therapy is effective in patients with ESRD and hepatitis C, including those with liver cirrhosis. Its use may be recommended especially in countries where other drugs are not available. Due to limited experience however, patients should be closely monitored for adverse effects. Hypoglycemia may be a potential adverse effect of sofosbuvir and daclatasvir therapy.

Hepatitis C care continuum and associated barriers among people who inject drugs in Chennai, India. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 57:51-60.

Abstract
BACKGROUND Little is known regarding barriers to hepatitis C virus (HCV) treatment among people who inject drugs (PWID) in low-resource settings, particularly in the era of direct-acting antiviral therapies. METHODS Between March, 2015-August, 2016, a cross-sectional survey was administered to community-based PWID in Chennai, India to examine the HCV care continuum and associated barriers. Adjusted prevalence ratios (APR) were estimated by multivariable Poisson regression with robust variance. RESULTS All participants were male (n = 541); 152 participants had HCV mono-infection and 61 participants had HIV/HCV co-infection. Only one HCV mono-infected and one HIV/HCV co-infected participant was linked to HCV care. Overall, there was moderate knowledge of HCV disease but poor knowledge of HCV treatment. Higher total knowledge scores were negatively associated with HIV/HCV co-infection (vs. HCV mono-infection), though this was not statistically significant in adjusted analysis (APR = 0.71 [95%CI = 0.47-1.06]). Participants ≥45 years (APR = 0.73 [95%CI = 0.58-0.92]) and participants with HIV/HCV co-infection (APR = 0.64 [95%CI = 0.47-0.87]) were less willing to take weekly interferon injections for 12 weeks. Willingness to undergo HCV treatment improved with decreasing duration of therapy, higher perceived efficacy, and use of pills vs. interferon, though willingness to use interferon improved with decreasing duration of therapy. Most participants preferred daily visits to a clinic for HCV treatment versus receiving a month's supply. Participants ≥45 years (vs. <45 years; APR = 0.70 [95%CI = 0.56-0.88]) and participants with HIV/HCV co-infection (APR = 0.75 [95%CI = 0.57-0.98]) were less likely to intend on seeking HCV care. Common reasons for not having already seen a provider for HCV treatment differed by HIV status, and included low perceived need for treatment (HCV-mono-infected), competing money/health priorities and costs/fears about treatment (HIV/HCV-co-infected). CONCLUSION Residual gaps in HCV knowledge and continuing negative perceptions related to interferon-based therapy highlight the need to scale-up educational initiatives. Readiness for HCV treatment was particularly low among HIV/HCV co-infected and older PWID, emphasizing the importance of tailored treatment strategies.

Abstract
CONTEXT Host factors including single-nucleotide polymorphisms (SNPs) in or near interferon lambda (IFNL) gene are the important factors in predicting response to treatment of chronic hepatitis C (CHC). AIMS The aim of this study was to determine the frequency and association of IFNL4 rs368234815 with IFNL3 SNPs rs12979860, rs8099917 and other factors including cholesterol, alanine aminotransferase, fibrosis, viral load, age and body mass index in genotype 1a treated CHC patients, to achieve rapid virologic response (RVR) and sustained virologic response (SVR). SUBJECTS AND METHODS A total of 71 hepatitis C virus genotype 1a patients were enrolled from 2013 to 2015. The genotypes of rs12979860, rs8099917 were identified by polymerase chain reaction (PCR) and restriction fragment length polymorphism while the genotype rs368234815 detected by amplification-refractory mutation system-PCR. RESULTS The rate of RVR and SVR were 43/71 (60.6%) and 46/71 (64.8%), respectively. To achieve an SVR in patients with rs368234815, TT/TT genotype 20/24 (83.3%) was found to be higher than other SNPs. The correlation coefficient of rs368234815 was strongly associated with rs12979860 (r = 0.788, P < 0.001). Multivariate logistic regression showed that the cholesterol (odds ratio [OR]: 0.205, confidence interval [CI] 95%: 0.047-0.891, P = 0.035), age (OR: 0.160, CI 95%: 0.035-0.730, P = 0.018), baseline viral load (OR: 0.167, CI 95%: 0.032-879, P < 0.035) and IFNL4 (OR: 5.453, CI 95%: 1.015-29.293, P < 0.048) could be independent predictors of SVR. CONCLUSIONS The results of these findings emphasise that factors such as age, cholesterol, baseline viral load and IFNL4 rs368234815 are better predictive factors and should be evaluated before CHC treatment.

Abstract
Hepatitis B Virus (HBV) infection is one of the major causes of morbidity, mortality and healthcare expenditure in India. There are no Indian consensus guidelines on prevention, diagnosis and management of HBV infection. The Indian National Association for Study of the Liver (INASL) set up a taskforce on HBV in 2016, with a mandate to develop consensus guidelines for diagnosis and management of HBV infection, relevant to disease patterns and clinical practices in India. The taskforce first identified contentious issues on various aspects of HBV management, which were allotted to individual members of the taskforce who reviewed them in detail. A 2-day round table discussion was held on 11th and 12th February 2017 at Port Blair, Andaman & Nicobar Islands, to discuss, debate, and finalize the consensus statements. The members of the taskforce reviewed and discussed the existing literature threadbare at this meeting and formulated the 'INASL position statements' on each of the issues. The evidence and recommendations in these guidelines have been graded according to the Grading of Recommendations Assessment Development and Evaluation (GRADE) system with minor modifications. The strength of recommendations (strong: 1, weak: 2) thus reflects the quality (grade) of underlying evidence (A, B, C, D). We present here the INASL position statements on prevention, diagnosis and management of HBV in India.

Abstract
BACKGROUND There is no published data of treating hepatitis C in thalassemia major patients with any sofosbuvir based direct acting antivirals (DAAs). This study was performed to determine the efficacy and safety of these regimes using generic drugs in the thalassemia major population. METHODS In this observational study, 902 patients of thalassemia major from five transfusion centres in Mumbai were screened for HCV antibody. Of the 120 positive patients, HCV RNA was detected in 50%. The first 29 patients were enrolled for evaluating the efficacy and safety of generic sofosbuvir based DAAs. RESULTS The 29 patients' had a mean age of 24 years with genotype 1 in 17, genotype 3 in 11patients, while 1 patient's genotype could not be classified. Six patients had compensated cirrhosis and 8 patients were treatment experienced. SVR 12 was achieved in 100% of patients. There was significant increase in PRC (packed red cell) requirements (P = 0.0003) during treatment. At 12 weeks post-treatment, PRC requirements returned to baseline with a significant fall in serum ferritin (P = 0.03). Headache, fatigue and diarrhoea were the most common side effects. The difference in side effects including anaemia between patients who received ribavirin (19/29) and those who did not receive ribavirin (10/29) was not significant. Presence of diabetes, splenectomy, high ferritin or liver or heart iron overload on MRI T2* did not affect the efficacy of treatment. CONCLUSION Generic DAAs are safe in thalassemia major patients with hepatitis C with efficacy of 100%. Serum ferritin falls significantly after treatment despite an increase in transfusion requirements during treatment.

Abstract
BACKGROUND Recurrent hepatitis C virus (HCV) has been a serious problem after liver transplantation (LT). We report our experience of 24-week therapy with sofosbuvir (SOF) and ribavirin (RBV) in post-LT recurrent HCV in living donor liver transplantation (LDLT) setting in South Asia. METHODS Data from all patients treated for post-transplantation HCV recurrence in a single center were analyzed. Treatment regimen was 24 weeks of SOF 400 mg daily and RBV (starting at 800 mg daily, increased as tolerated). Sustained virological response (SVR) was assessed 12 weeks and 24 weeks after completion of treatment. RESULTS 63 patients (median age 52 [range 30-69] years; 80% males) were treated. Most (76.2%) were treatment experienced and predominant HCV genotype was 3 (77.7%) followed by 1 (20.6%). Median transient elastography (Fibroscan) score was 7 (range 3-11) kPa and none of the patients had cirrhosis. SVR12 was achieved in 60 of 63 patients (95.2%) while SVR24 was noted in 59 (93.7%). SVR12 rates were as good in genotype-3 as in genotype-1. Older age, longer period after transplantation, higher Fibroscan value and higher need for erythropoietin were likely to be associated with relapse. Adverse effects were noted in 34 patients and weakness and fatigue were the commonest side effects. Significant drop in hemoglobin (<8 g/dL) was seen in 6 patients. CONCLUSIONS SOF + RBV combination therapy for 24 weeks was safe and effective in treatment of for post-LT recurrent HCV in a single LT center and remains relevant due to its low cost and lack of drug interactions.

Abstract
Genome-wide association studies discovered interferon lambda (IFNL or IFN-λ) locus on chromosome 19 to be involved in clearance of chronic hepatitis C virus (HCV) infection in patients following interferon-α-ribavirin (IFN-RBV) therapy. Subsequent studies established a dinucleotide polymorphism rs368234815, as the prime causal variant behind this association. The ΔG allele of this variant gives rise to a new IFNL gene, IFNL4, coding for IFN-λ4 whose activity paradoxically associates with lesser viral clearance rates. A low-frequency, nonsynonymous single nucleotide polymorphism (SNP) rs117648444 within the 2nd exon of IFNL4 changes the 70th amino acid from proline to serine resulting in lower activity of the functional IFN-λ4 protein, thereby increasing HCV clearance rates. In the present study, we used a cohort of genotype 3 HCV-infected patients, drawn from different geographical regions of India who underwent IFN-RBV therapy, to examine the association of several important IFNL locus SNPs/variants with sustained virological response (SVR). Intriguingly, the causal variant rs368234815 did not show the best strength and significance of association with SVR, while further analysis revealed that a negative confounding effect of rs117648444 was responsible for this phenomenon. Our results indicate that IFNL locus SNPs are subject to either a positive or a negative confounding effect by rs117648444; the nature of confounding depends on the linkage of the IFNL SNPs with the low-activity IFN-λ4-generating minor allele of rs117648444. Thus, our work demonstrates that the linkage disequilibrium structure of the IFNL region may confound the results of association studies. These results have implications for the design and understanding of future case-control studies involving IFNL locus SNPs/variants.

Abstract
Treatment of hepatitis C virus (HCV) with newer directly acting antivirals (DAAs) and lead to sustained viral response (SVR) in majority of patients and SVR has been documented to be associated with reversal of liver cirrhosis. The improved SVR rates and safety profiles of DAAs have led to the treatment of patients with decompensated cirrhosis awaiting liver transplantation (LT). Several clinical trials of DAAs in decompensated HCV patients have recently demonstrated SVR rates above 80%, which have been associated with significant improvements, in the Child-Pugh-Turcotte scores/or model for end-stage liver disease scores in a proportion of patients. Moreover, it has been shown that HCV RNA becomes negative after 2-4 weeks of treatment, and those who are transplanted after becoming HCV RNA negative will be have very low the risk of HCV recurrence after transplantation. Some of the patients may have reached the "point of no return" and may proceed to worsening of decomposition over time. To avoid the risk of worsening, there is an additional option of treating these patients after LT should they develop recurrent HCV infection. Currently there are no guidelines as to select patients who would benefit from treatment prior to LT as opposed to those who will be better off being treated after the transplant surgery. The article discusses a possible approach for such selection.

Abstract
In recent past, direct-acting anti-viral drugs (DAAs) have become the standard of care for the treatment of hepatitis C virus (HCV) infection. However, the experience with the use of these drugs in Indian renal transplant recipients is limited. We retrospectively reviewed our experience with DAA-based treatment for HCV infection in such patients. Between April 2015 and December 2016, six adults (median age 41 [range 34-52] years, male 5; GT1 2, GT3 3, and GT4 1; including three with prior failed interferon-based treatment) had received genotype-guided, DAA-based anti-HCV treatment 1 to 158 (median 15) months after renal transplantation. Of them, four completed the planned 24-week treatment without any significant adverse event. One of them had increase in serum creatinine after 16 weeks of treatment with sofosbuvir and daclatasvir, with acute interstitial nephritis on kidney biopsy; his renal function improved on stopping the drugs. The other patient had preexisting mild renal dysfunction, which worsened after 8 weeks of sofosbuvir-ledipasvir treatment; this did not reverse on stopping treatment. All the six patients achieved undetectable HCV RNA after 4 weeks of treatment and also achieved sustained virologic response, i.e. lack of detectable HCV RNA in serum 12 weeks after stopping treatment. Overall, DAA-based treatment was effective in treating HCV infection in our renal transplant recipients; however, caution and monitoring of renal function during such treatment is advisable in patients who have additional factors that predispose to renal injury.
