Sofosbuvir-Velpatasvir Fixed Drug Combination for the Treatment of Chronic Hepatitis C Infection in Patients With End-Stage Renal Disease and Kidney Transplantation.

ABSTRACT:

Introduction

India is witnessing high hepatitis C virus (HCV) infection burden in patients of chronic kidney disease. Due to unavailability of costly Kidney Disease Improving Global Outcomes-recommended directly acting antiviral drugs, a widely available pan-genotypic combination of Sofosbuvir and Velpatasvir can become an economical option. Data regarding treatment experience of sofosbuvir-velpatasvir combination in chronic kidney disease is scarce. No data from India have been published in patients on renal replacement therapies till now.

Methods

This retrospective analysis included all patients of end-stage renal disease on maintenance hemodialysis with treatment-naïve chronic HCV infection treated with sofosbuvir (400 mg) and velpatasvir (100 mg) fixed-dose combination. Pretreatment routine investigations were performed, which included HCV viral load, genotype, fibro scan, endoscopy for esophageal varices, and portal vein Doppler. The patients were followed up with HCV viral load to declare sustained virologic response.

Result

patients were included with a mean age of 39.8 ± 10.8 years, and 77.4% were male. Genotype 1 was found to be most prevalent (67.7%), with a median viral load of 10⁶copies/ml. Six (19.3%) patients had hepatitis B virus co-infection. Three (9.7%) patients had cirrhosis. Sustained virologic response (SVR12) was achieved in 30 (96.8%) patients, and one (3.2%) patient had relapse. Furthermore, 14 (45.2%) patients underwent renal transplantation, and none of them had relapsed. Dyspepsia (9.7%) was the most common side effect observed with no major adverse effect.

Conclusion

Our study showed excellent efficacy with the safety profile of this drug combination in end-stage renal disease patients. However, larger prospective studies and multicenter randomized controlled trials are needed for further confirmation.

Project description:BACKGROUND:Cardiovascular disease is a significant cause of morbidity and mortality in patients with end-stage renal disease (ESRD) and kidney transplant (KT) patients. Compared with left ventricular (LV) ejection fraction (LVEF), LV strain has emerged as an important marker of LV function as it is less load dependent. We sought to evaluate changes in LV strain using cardiovascular magnetic resonance imaging (CMR) in ESRD patients who received KT, to determine whether KT may improve LV function. METHODS:We conducted a prospective multi-centre longitudinal study of 79 ESRD patients (40 on dialysis, 39 underwent KT). CMR was performed at baseline and at 12?months after KT. RESULTS:Among 79 participants (mean age 55 years; 30% women), KT patients had significant improvement in global circumferential strain (GCS) (p?=?0.007) and global radial strain (GRS) (p?=?0.003), but a decline in global longitudinal strain (GLS) over 12?months (p?=?0.026), while no significant change in any LV strain was observed in the ongoing dialysis group. For KT patients, the improvement in LV strain paralleled improvement in LVEF (57.4?±?6.4% at baseline, 60.6%?±?6.9% at 12?months; p?=?0.001). For entire cohort, over 12?months, change in LVEF was significantly correlated with change in GCS (Spearman's r?=?-?0.42, p?<?0.001), GRS (Spearman's r?=?0.64, p?<?0.001), and GLS (Spearman's r?=?-?0.34, p?=?0.002). Improvements in GCS and GRS over 12?months were significantly correlated with reductions in LV end-diastolic volume index and LV end-systolic volume index (all p?<?0.05), but not with change in blood pressure (all p?>?0.10). CONCLUSIONS:Compared with continuation of dialysis, KT was associated with significant improvements in LV strain metrics of GCS and GRS after 12?months, which did not correlate with blood pressure change. This supports the notion that KT has favorable effects on LV function beyond volume and blood pessure control. Larger studies with longer follow-up are needed to confirm these findings.

Project description:Background and aim For years, interferon-based treatment has been offered to patients with chronic hepatitis C virus (HCV) infection; however, the complexity of the treatment, efficacy, and adverse effects were the primary concerns. All these concerns were addressed with the introduction of directly acting antivirals (DAAs) to treat chronic HCV. Sofosbuvir and velpatasvir are second-generation DAAs used in combination for the treatment of chronic HCV infection. The aim of our study was to determine and compare the efficacy and safety profile of the sofosbuvir and velpatasvir combination in treating patients with chronic hepatitis C with or without cirrhosis. Materials and methods This descriptive study was conducted at the Department of Medicine, Khyber Teaching Hospital, Peshawar, from March 15th to September 15th, 2021 after approval from the Institution Research and Ethical Review Board (IREB). Diagnosis of HCV was based on the detection of hepatitis C ribonucleic acid (RNA) fragments by reverse transcription-polymerase chain reaction (RT-PCR). Liver status was assessed with liver function tests and imaging. Sofosbuvir (400 mg) and velpatasvir (100 mg) were administered once daily for 12 weeks, followed by polymerase chain reaction (PCR) for HCV RNA after 12 weeks of completion of treatment for determination of sustained virologic response at 12 weeks (SVR12). Patients with cirrhosis also received weight-based ribavirin. Adverse events experienced by the study participants during the course of treatment were recorded. Data were collected regarding patients' demographics, laboratory parameters, SVR12, and adverse events, and were then analyzed using SPSS, version 22 (IBM SPSS Statistics, Armonk, NY). Results A total of 58 patients with cirrhosis and 58 patients without cirrhosis with chronic HCV were enrolled. The rate of SVR12 in patients with cirrhosis was 89.7% (52 patients achieved SVR12), compared to 98.3% in patients without cirrhosis (57 patients achieved SVR12). Subgroup analysis of patients with cirrhosis revealed that patients who have failed to achieve SVR12 were mostly males, had prolonged disease duration, and low hemoglobin at baseline; however, the association of these factors with SVR12 was not significant. The incidence of adverse events among all study participants was 46.5%. Among the cirrhotic cohort, 37 (63.8%) patients experienced adverse events, while only 17 (29.3%) patients among the non-cirrhotic cohort had adverse events. A total of 24 patients with cirrhosis (41.37%) reported mild complaints. The most commonly reported adverse event was gastrointestinal (GI) upsets (46.2%), followed by fatigue (33.9%), while 19.9% developed miscellaneous adverse events such as headaches, rash, and insomnia. Conclusion The combination of sofosbuvir and velpatasvir is highly effective and safe in patients with HCV with or without cirrhosis. However, this combination's efficacy was slightly higher in non-cirrhotic patients (98.3%) than in cirrhotic patients (89.7%).
