Abstract
Chronic infection with the hepatitis C virus (HCV) remains a major health problem affecting approximately 58 million people worldwide. In the era of interferon (IFN)-based regimens, patients particularly infected with genotypes 1 and 4 achieved a low response rate. The implementation of direct-acting antivirals changed the landscape of HCV treatment. The increase in effectiveness provided us with the hope of eliminating HCV as a significant public threat by 2030. In the following years, there was an observed improvement in the treatment of HCV with genotype-specific regimens and highly effective pangenotypic options that are the most recent stage of the revolution. The optimization of therapy was accompanied by changes in the patient profile from the beginning of the IFN-free era over time. Patients treated with antiviral therapies were younger in successive periods, less burdened with comorbidities and comedications, more frequently treatment-naïve and had less advanced liver disease. Before the IFN-free era, specific subpopulations such as patients with HCV/HIV coinfection, those with a history of previous treatment, patients with renal impairment or with cirrhosis had lower chances for a virologic response. Currently, these populations should no longer be considered difficult to treat. Despite the high effectiveness of HCV therapy, there is a small percentage of patients with treatment failure. However, they can be effectively retreated with pangenotypic rescue regimens.

Abstract
Background: Approximately 3% of the population worldwide is infected with Hepatitis C Virus (HCV). Different regimens have been used to treat HCV, each of which has its side effects and efficacy. Sofosbuvir, a direct-acting antiviral drug, has replaced all previous regimens with the highest response rate. However, its response is not fully covered in Pakistan, especially Khyber Pakhtunkhwa. Objectives: The study aimed to examine the response to Sofosbuvir and Ribavirin combination therapy in chronic HCV patients infected with various HCV genotypes. Methods: This study was conducted in Tertiary Care Hospitals, Peshawar, Pakistan. The patients were enrolled from January 2016 to March 2017. A total of 80 patients (57 naïve and 23 non-responder) were enrolled in this study. The age range was 16 - 70 years, and the mean age was 36 ± 2 years. Genotyping, biochemical profile, PCR tests, and liver ultrasounds were done for all of the enrolled subjects at the start and end of therapy. All patients were given direct-acting antiviral drugs for six months and then, the end of treatment response was noted. Results: A total of 80 subjects with HCV infection took part in the study, including 57 (71.25%) treatment-naïve and 23 (28.75%) treatment non-responding patients. The end of therapy response was reported after 24 weeks of treatment. Among the 80 patients, 72 (90%) patients achieved the end of therapy response. The highest end of therapy response (100%) was noted in genotype 1 and mixed genotypes and patients with normal liver ultrasound. The lowest end of therapy response (70%) was found in un-type genotype and patients with an abnormal texture of liver ultrasound. The end of therapy response rate was higher in females than in males. Conclusions: In the current study, the minimal response was found in un-type genotypes and genotypes that did not respond to INF, as compared to treatment-naïve subjects. Further research is needed to understand the relevant host and viral factors, with particular attention to relapsed patients and non-responders that are difficult to treat in the Pakistani population.

Abstract
The aim of the study is to analyze treatments available for patients infected with genotype (G) 3 hepatitis C virus (HCV) in Poland at the beginning of the interferon (IFN)-free era and evaluate the efficacy and safety of different therapeutic options administered in a real-world setting. We analyzed data of 198 patients who started antiviral therapy after July 1, 2015, and completed it before December 31, 2016; 57.6% of them had liver cirrhosis and 46% were treatment experienced. Fifty percent of patients were assigned to sofosbuvir (SOF)+pegylated IFN alfa (PegIFNa)+ribavirin (RBV), 9% to PegIFNa+RBV, 36% received SOF+RBV, and 5% SOF+daclatasvir (DCV)±RBV. Cirrhotic patients were assigned more frequently to IFN-free regimens. Overall, a sustained virological response was achieved by 84.3% of patients in intent-to-treat (ITT) analysis and 87% in modified ITT analysis. For SOF+PegIFNa+RBV and SOF+DCV±RBV regimens, the sustained virologic response (SVR) rate reached at least 90%, whereas the two other therapeutic options demonstrated efficacy <80%. The SVR rate in noncirrhotics was higher than in cirrhotics, irrespective of regimen. Adverse events were documented in 52.5%, with the most common being weakness/fatigue and anemia. We confirmed effectiveness and safety of the SOF-based treatment in a real-world cohort of patients with chronic HCV G3 infection. Most notably, we demonstrated good tolerability and high efficacy of the SOF+PegIFNa+RBV regimen.

Successful treatment of chronic hepatitis C infection with directly acting antivirals in renal transplant recipients. Nephrology (Carlton) 2018; 23:876-882. [PMID: 28703905 DOI: 10.1111/nep.13109] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/30/2017] [Indexed: 12/15/2022]
Abstract
AIMS The data regarding the treatment of chronic hepatitis C (CHC) in renal transplant recipients is lacking from the Asia-Pacific region. The aim of the present study was to assess the safety and efficacy of directly acting antivirals (DAAs) in the treatment of CHC infection in renal transplant recipients. METHODS A total of 47 CHC infected renal transplant recipients were enrolled in this real life observational cohort analysis between March 2015 and September 2016. Presence of hepatic fibrosis/cirrhosis was assessed on transient elastography (Fibroscan). Fourteen patients were treated with Sofosbuvir and Ribavirin for 24 weeks. Twenty-two patients received Sofosbuvir and Ledipasvir and 12 patients received Sofosbuvir and Daclatasvir with (n = 3) or without (n = 31) Ribavirin for 12 or 24 weeks depending on genotype and underlying cirrhosis. Data were analyzed for safety and treatment efficacy [sustained virological response at 12 weeks (SVR12)]. RESULTS The median baseline HCV RNA concentration in the whole group was 7.38 × 106 IU/mL (1.23 × 104 -6.36 × 107 ). The SVR12 rates were 100% in all groups except in the Sofosbuvir and Ribavirin group (86%). Transient Elastography revealed minimal or no fibrosis (F0-F1) in 31 (65.96%) patients, moderate fibrosis (F2) in 11 (23.4%) patients and cirrhosis in five (10.64%) patients. The only serious adverse effect was anaemia observed in eight (57%) patients in the Sofosbuvir and Ribavirin group. CONCLUSION DAAs including Sofosbuvir, Daclatasvir and Ledipasvir with or without ribavirin are safe and effective for the treatment of chronic hepatitis C in renal transplant recipients.

Abstract
In Pakistan, the burden of the hepatitis C virus (HCV) infection is the second highest in the world with the development of chronic hepatitis. Interferon-based combination therapy with ribavirin was the only available treatment until a few years back, with severe side-effects and high failure rates against different genotypes of HCV. Interferon-free all-oral direct-acting antiviral agents (DAAs) approved by the FDA have revolutionized the HCV therapeutic landscape due to their efficiency in targeting different genotypes in different categories of patients, including treatment naïve, treatment failure and relapsing patients, as well as patients with compensated and decompensated cirrhosis. The availability and use of these DAAs is limited in the developing world. Sofosbuvir (SOF), a uridine nucleotide analogue and inhibitor of HCV encoded NS5B polymerase, is now a widely available and in-use DAA in Pakistan; whereas daclatasvir was recently added in the list. According to the documented results, there is hope that this disease can be effectively cured in Pakistan, although a few concerns still remain. The aim of this article is to review the effectiveness of DAAs and the current status of this treatment against HCV genotype 3 infection in Pakistan; various factors associated with SVR; its limitations as an effective treatment regime; and future implications.

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.

Low-Dose Sofosbuvir Is Safe and Effective in Treating Chronic Hepatitis C in Patients with Severe Renal Impairment or End-Stage Renal Disease. Dig Dis Sci 2018; 63:1334-1340. [PMID: 29484572 DOI: 10.1007/s10620-018-4979-6] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Accepted: 02/12/2018] [Indexed: 12/23/2022]
Abstract
BACKGROUND AND AIMS There is sparse data on the use of Sofosbuvir based directly acting antiviral (DAA) drug regimens in chronic hepatitis C (CHC) patients with chronic kidney disease (CKD) with estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m2. We evaluated the safety and efficacy of low-dose Sofosbuvir plus full-dose Daclatasvir in CHC patients with CKD. METHODS Sixty-five CHC patients with CKD with eGFR less than 30 mL/min/1.73 m2 [54 (83%) patients with ESRD on hemodialysis] were included. All patients irrespective of genotype were treated with half-dose Sofosbuvir [200 mg (half tablet of 400 mg)] plus full-dose Daclatasvir (60 mg) given daily for either 12 or 24 weeks given in patients with genotype 3 cirrhosis. The efficacy was assessed by the sustained virological response (SVR12) with negative HCV RNA 12 weeks after the end of treatment (ETR). RESULTS The median HCV RNA level in 65 patients (Males 40, mean age 42.9 ± 13 years) was 1.65 × 106 (1.2 × 103-1.73 × 108) IU/mL with 42 (64.6%) patients having HCV genotype 1, followed by genotype 3 and 2 in 22 (34%) and 1 (1.4%) patients, respectively. Twenty-one (32%) patients had evidence of cirrhosis, and ten (15.4%) patients were treatment experienced. Sixty-four (98.5%) patients achieved ETR, and 65 (100%) patients attained SVR12. All patients tolerated the DAAs well with none of the patients reporting any serious adverse events. Minor side effects noted were nausea seen in five (7.7%) patients, insomnia and headache in four (6.2%) patients each, and pruritus in one (1.5%) patient. CONCLUSION Low-dose Sofosbuvir and full-dose Daclatasvir are safe and effective in treating CHC in patients with CKD with eGFR less than 30 mL/min/1.73 m2.

Systematic review with meta-analysis: effectiveness and tolerability of interferon-free direct-acting antiviral regimens for chronic hepatitis C genotype 1 in routine clinical practice in Asia. Aliment Pharmacol Ther 2018; 47:550-562. [PMID: 29327780 DOI: 10.1111/apt.14507] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2017] [Revised: 11/22/2017] [Accepted: 12/17/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking. AIM To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia. METHODS We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017. The pooled SVR rates were computed with a random-effects model. Subgroup analysis and meta-regression as previously registered in PROSPERO were performed to determine how pre-planned variables might have affected the pooled estimates. RESULTS We included 41 studies from eight countries and regions, comprising of 8574 individuals. The pooled SVR rates for GT1 were 89.9% (95% CI 88.6-91.1, I2 = 55.1%) with daclatasvir/asunaprevir (DCV/ASV) and 98.1% (95% CI 97.0-99.0, I2 = 41.0%) with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV). Baseline cirrhosis but not prior treatment history and age, attenuated the effectiveness of both regimens. Baseline resistance associated substitutions (RASs) severely attenuated SVR of DCV/ASV (65.4% vs 94.3%, P < 0.001) and only minimally with LDV/SOF ± RBV (94.5% vs 99.2%, P = 0.003). Patients with renal dysfunction treated with DCV/ASV showed a higher SVR rate (93.9% vs 89.8%, P = 0.046). Patients with hepatocellular carcinoma (HCC) LDV/SOF ± RBV achieved a lower SVR than those without HCC (94.1% vs 98.7%, P = 0.001). CONCLUSION All oral DAA treatment of HCV GT1 resulted in high cure rates in Asian patients in routine clinical practice setting including elderly patients and those with end-stage renal disease.

Abstract
BACKGROUND AND AIM Direct antiviral agents (DAAs) have led to high sustained virological responses (SVR) in hepatitis C virus (HCV) patients. However, genotype 3 patients respond to treatment in a suboptimal way. This study aims to identify which of the several treatment schedules recommended for genotype 3 would constitute the best option. METHODS Twenty-four Italian centers were involved in this real-life study of HCV genotype 3 patients treated with DAAs. To expand the number of cases, we conducted a systematic review of the literature on the outcome of genotype 3 patients treated with DAAs. RESULTS A total of 233 patients with HCV genotype 3 were enrolled. Cirrhotic patients accounted for 83.7%. Overall, the SVR12 rate was achieved by 205 patients (88.0%); the SVR rates were 78.8% after sofosbuvir/ribavirin, 92.5% after sofosbuvir/daclatasvir ± ribavirin, and 100% after sofosbuvir/ledipasvir (seven patients). No difference in rate of SVR was observed in cirrhotic and non-cirrhotic patients (92.2 vs 94.4) using a combination regimen of NS5A and NS5B inhibitors.The systematic review of the literature provided data of 3311 patients: The mean weighted SVR12 rate was 84.4% (CI: 80.4-87.8); the rates varied from 79.0% (CI: 70.9-85.3) with sofosbuvir/ribavirin, to 83.7% (CI: 66.2-93.1) with sofosbuvir/ledispavir, and to 88.2% (CI: 83.3-91.7) with sofosbuvir/daclatasvir. CONCLUSIONS Our results reinforce the concept that patients with HCV genotype 3 should no longer be considered difficult-to-treat individuals. The optimal therapeutic regimen for these patients appears to be the combination sofosbuvir/daclatasvir, administered for 12 weeks without the use of RBV in non-cirrhotic patients. In cirrhotics the meta-analytic approach suggests extending therapy to 24 weeks.

Abstract
AIM To assess the real-world effectiveness and cost of simeprevir (SMV), and/or sofosbuvir (SOF)-based therapy for chronic hepatitis C virus (HCV) infection.
METHODS The real-world performance of patients treated with SMV/SOF ± ribavirin (RBV), SOF/RBV, and SOF/RBV with pegylated-interferon (PEG) were analyzed in a consecutive series of 508 patients with chronic HCV infection treated at a single academic medical center. Patients with genotypes 1 through 4 were included. Rates of sustained virological response - the absence of a detectable serum HCV RNA 12 wk after the end of treatment [sustained virological response (SVR) 12] - were calculated on an intention-to-treat basis. Costs were calculated from the payer’s perspective using Medicare/Medicaid fees and Redbook Wholesale Acquisition Costs. Patient-related factors associated with SVR12 were identified using multivariable logistic regression.
RESULTS SVR12 rates were as follows: 86% (95%CI: 80%-91%) among 178 patients on SMV/SOF ± RBV; 62% (95%CI: 55%-68%) among 234 patients on SOF/RBV; and 78% (95%CI: 68%-86%) among 96 patients on SOF/PEG/RBV. Mean costs-per-SVR12 were $174442 (standard deviation: ± $18588) for SMV/SOF ± RBV; $223003 (± $77946) for SOF/RBV; and $126496 (± $31052) for SOF/PEG/RBV. Among patients on SMV/SOF ± RBV, SVR12 was less likely in patients previously treated with a protease inhibitor [odds ratio (OR): 0.20, 95%CI: 0.06-0.56]. Higher bilirubin (OR: 0.47, 95%CI: 0.30-0.69) reduced the likelihood of SVR12 among patients on SOF/RBV, while FIB-4 score ≥ 3.25 reduced the likelihood of SVR12 (OR: 0.18, 95%CI: 0.05-0.59) among those on SOF/PEG/RBV.
CONCLUSION SVR12 rates for SMV and/or SOF-based regimens in a diverse real-world population are comparable to those in clinical trials. Treatment failure accounts for 27% of costs.

Abstract
This study aimed to explore changes in hepatic and renal function indices in chronic hepatitis C (CHC) patients treated with direct-acting antivirals (DAAs). Forty-three CHC patients treated with sofosbuvir (SOF)-containing regimens were enrolled. At the end of treatment, the estimated glomerular filtration rate (eGFR) level was significantly decreased and the serum creatinine (Scr) and uric acid (UA) levels were significantly increased compared with baseline levels (eGFR: 86.7 ± 20.4 vs 80.5 ± 21.3, P01 = 0.005; Scr: 83.9 ± 19.1 vs 89.6 ± 21.1, P01 < 0.001; UA: 323.7± 86.2 vs 358.5 ± 93.2, P01 < 0.001); no significant improvements were observed at 24 w post-treatment (eGFR: 86.7 ± 20.4 vs 81.4 ± 18.6, P02 = 0.013; Scr: 83.6 ± 17.9 vs 87.9 ± 18.3, P02 = 0.014; UA: 320.8 ± 76.3 vs 349.3 ± 91.0, P02 = 0.004). When the patients were grouped by liver conditions, non-cirrhotic patients and cirrhotic patients had decreased eGFR levels and increased Scr levels at the end of treatment; at 24 w post-treatment, the eGFR and Scr levels were significantly improved in non-cirrhotic patients (88.4 ± 21.7 vs 83.8 ± 18.5, P02 = 0.142; 84.4 ± 20.4 vs 87.0 ± 16.9, P02 = 0.088), while no obvious improvements were observed in cirrhotic patients (84.3 ± 18.7 vs 78.1 ± 18.6, P02 = 0.002; 83.2 ± 17.7 vs 89.2 ± 20.6, P02 = 0.006). Clinical physicians should closely monitor renal function in patients treated with SOF-containing regimens, especially in cirrhotic patients.

Abstract
AIM To assess the efficacy and safety of combined directly acting antivirals (DAAs) for the treatment of Chinese chronic hepatitis C (CHC) patients in a real-world setting.
METHODS Hospitalized CHC patients who were treated with DAAs at Peking University First Hospital between January 2015 and December 2016 were enrolled. Samples and clinical data were collected at 0 wk, 2 wk, 4 wk, 8 wk, 12 wk, or 24 wk during DAAs treatment and at 4 wk, 12 wk, and 24 wk after the end of treatment.
RESULTS Fifty-four patients who underwent DAAs treatment were included in our study, of whom 83.3% (45/54) achieved rapid virological response at 2 wk after treatment initiation (RVR 2) and 94.4% (51/54) achieved sustained virological response at 24 wk after the end of treatment (SVR 24). Serum creatinine and uric acid levels at the end of treatment were significantly increased compared with baseline levels (83.6 ± 17.9 vs 88.8 ± 19.4, P01 < 0.001; 320.8 ± 76.3 vs 354.5 ± 87.6, P01 < 0.001), and no significant improvements were observed at 24w after the end of treatment (83.6 ± 17.9 vs 86.8 ± 19.1, P02 = 0.039; 320.8 ± 76.3 vs 345.9 ± 89.4, P02 = 0.001). The total frequency of adverse events (AEs) during treatment was 33.3% (18/54), with major AEs being fatigue (16.7%), headache (7.4%), anorexia (7.4%), and insomnia (5.6%).
CONCLUSION Though based in a small cohort of patients, the abnormal changes in renal function indices and relative high frequency of AEs during combined DAAs treatment should be taken as a note of caution.

Abstract
BACKGROUND Direct-acting antiviral drugs (DAAs) are favored for the treatment of hepatitis C virus (HCV) infection. However, the experience with the DAAs currently available in India in the treatment of genotype-3 HCV is limited. We therefore reviewed our experience with these drugs in treating patients with chronic genotype-3 HCV infection, including those with cirrhosis. METHODS We prospectively followed adult patients with genotype-3 HCV infection who had received treatment regimens containing sofosbuvir with/without daclatasvir. Patients were categorized as chronic hepatitis C (CHC), compensated cirrhosis (CC), and decompensated cirrhosis (DC). They received either (i) sofosbuvir and ribavirin, with or without pegylated interferon (Peg-IFN) for 12 or 24 weeks, or (ii) sofosbuvir and daclatasvir, with or without ribavirin for 12 or 24 weeks. Response was assessed using HCV RNA testing after 2 or 4 weeks of treatment (rapid virological response [RVR]), at treatment completion (end-of-treatment response [ETR]) or 12 weeks after treatment completion (sustained virological response [SVR12]). RESULTS Of the 160 patients (90% treatment-naïve; CHC 49%, CC 32%, and DC 19%), 39 (24%) received Peg-IFN, sofosbuvir and ribavirin, 21 (13%) received sofosbuvir and ribavirin, and 100 (63%) received sofosbuvir and daclatasvir, with or without ribavirin. On intention-to-treat basis, RVR, ETR, and SVR12 in the entire cohort were 146/160 (91.3%), 151/160 (94.4%), and 147/160 (91.9%), respectively. Seven patients died (CC 2, DC 5) during treatment; four (2 CHC, 2 DC) patients discontinued treatment; and two patients with CC relapsed. CONCLUSIONS Dual-DAA-based regimens were safe and highly effective in treating genotype-3 HCV infection in CHC and CC patients.

Abstract
Background The burden of hepatitis C (HCV) infection in Pakistan is among the highest in the world, with a reported national HCV prevalence of 6.7% in 2014. In specific populations, such as in urban communities in Karachi, the prevalence is suspected to be higher. Interferon-free treatment for chronic HCV infection (CHC) could allow scale up, simplification and decentralization of treatment to such communities. We present an interim analysis over the course of February-December 2015 of an interferon-free, decentralised CHC programme in the community clinic in Machar Colony, Karachi, Pakistan. Design A retrospective analysis of a treatment cohort. Results There were 1,089 patients included in this analysis. Aspartate to platelet ratio index score was used to prioritize patients in terms of treatment initiation, with 242 patients placed in high priority for treatment and 202 starting treatment as scheduled. 169 patients started HCV treatment with Sofosbuvir-Ribavirin regimen according to HCV genotype over the course of 2015: of these, 35% had Hemoglobin reductions below 11.0 g/dl during the treatment course. Among the 153 patients (85%) with genotype 3 HCV infection, 84% of patients achieved sustained virologic response at 12 weeks following treatment completion (SVR 12). Conclusion Outcomes of HCV treatment with all oral combination in an integrated, decentralized model of care for CHC in a primary care setting, using simplified diagnostic and treatment algorithms, are comparable to the outcomes achieved in clinical trial settings for Sofosbuvir-based regimens. Our results suggest the feasibility and the pertinence if including interferon-free treatment regimens in the national programme, at both provincial and national levels.

Abstract
Background With the appearance of oral direct-acting antivirals (DAAs), the field of hepatitis C virus (HCV) treatment has been dramatically changed. This evolution makes possible for all oral treatments to be available for the treatment of HCV-infected patients. The aims of this review were to report the efficacy and safety of sofosbuvir (SOF)-based regimens for the treatment of patients with chronic HCV infection and to provide our clinical perspectives on these regimens. Methods A literature search of clinical studies published in PubMed and posted on ClinicalTrials.gov website was performed to identify studies evaluating the efficacy or safety of SOF-containing treatment regimens. Results A total of 23 clinical trials were examined in the review. The evaluated SOF-based regimens are as follows: SOF/daclatasvir (DCV) ± ribavirin (RBV), SOF/ledipasvir (LDV) ± RBV, SOF/simeprevir (SMV), SOF/velpatasvir (VEL) ± RBV, and SOF/RBV ± peginterferon (peg-IFN). These SOF-based regimens were at least effective and safe for HCV-infected patients with or without cirrhosis. The SOF/VEL ± RBV regimen, a pan-genotypic DAA regimen, was effective for the treatment of patients with HCV genotype 1, 2, 3, 4, 5, or 6 infection. The 24-week SOF/RBV regimen was as effective as the 12-week SOF/RBV/peg-IFN regimen. Patients with HCV genotype 3 infection could have benefits from the use of the 24-week SOF/RBV regimen. For cirrhotic patients with HCV genotype 3 infection, the 12-week SOF/RBV/peg-IFN regimen could be considered as an alternative treatment option when access to SOF-based regimens with other DAAs is limited. In the included studies, significant adverse events due to SOF-based regimens were not reported. Conclusion The clinical trials suggest that SOF-based treatment regimens for HCV-infected patients with or without cirrhosis can be at least effective and safe patient-convenient medications. However, it is necessary to monitor HCV-infected patients, since rare adverse events, drug–drug interactions, and drug–disease interactions can occur in real clinical settings.

Abstract
Objective: To compare sustained viral response to sofosbuvir/ribavirin ±interferon therapy in patients of hepatitis C with and without liver cirrhosis. Methods: This observational study of chronic hepatitis C patients was carried out at Doctors Hospital and Medical Center (DH&MC). After diagnostic workup, Sofosbuvir/ribavirin for 24 weeks or sofosbuvir/ribavirin/pegylated interferon for 12 weeks were prescribed. Primary outcome was negative HCV RNA by PCR 12 weeks after treatment completion (SVR12). Chi square χ2 and student’s t test were used to analyze data. Results: Of 216 patients included, liver cirrhosis was present in 112 (51.9%) patients and 69(31.9%) were treatment experienced. Liver disease was decompensated in 37 (17.1%) patients. Of 206 patient who completed study protocol, 173(83.1%) achieved SVR12, 89.2% (25/28) with triple therapy and 82.2% (148/180) with sofosbuvir/ribavirin therapy. Treatment response was similar between treatment naïve 86.2% (119/138) and treatment experienced 79.4% (54/68) patents. (p value 0.19) SVR12 was inferior in cirrhosis patients 75.4% (80/106) as compared to those with no cirrhosis 93% (93/100) (p value < 0.000). It was even lesser in those with decompensated liver disease 68.8% (24/35) (p value < 0.000). Conclusion: Treatment outcome with sofosbuvir/ribavirin combination therapy in cirrhosis patients is suboptimal especially in those with decompensation as compared to patients without liver cirrhosis.
