Abstract
Objective The main purpose of this study was to determine the end treatment response (ETR) and sustained viral response (SVR) in hepatitis C virus (HCV) patients receiving sofosbuvir and daclatasvir daily for 12 weeks. Methods This is a prospective open-label interventional study conducted from March 2018 to December 2020 in the outpatient departments of Abbasi Shaheed Hospital and Lyari General Hospital, Karachi. Patients with chronic infection of HCV, confirmed with ribonucleic acid (RNA) polymerase chain reaction (PCR) (qualitative analysis) were invited to participate in the study. All patients with positive HCV antibodies were evaluated clinically, with laboratory, and imaging assessment earlier to treatment. Statistical analysis was performed using SPSS version 20.0 (Armonk, NY: IBM Corp.). Results A total of 1043 patients participated in the study with a female predominance, 699 (67%) females. A majority (67.9%) of the study participants were aged between 15 and 45 years. After treatment of 12 weeks with sofosbuvir and daclatasvir 1039 (99.9%) patients achieved SVR while 1038 (99.6%) achieved an end treatment response. There was no significant association found between changes in alanine aminotransferase (ALT) levels, gender, and age among study participants. Conclusion Sofosbuvir and daclatasvir are found to be extremely effective for patients with hepatitis C in Pakistan. However, additional investigation including a larger sample size and involving a multicenter setting is recommended.

Safety and efficacy of four drug regimens versus standard-of-care for the treatment of symptomatic outpatients with COVID-19: A randomised, open-label, multi-arm, phase 2 clinical trial. EBioMedicine 2022; 86:104322. [PMID: 36332361 PMCID: PMC9624152 DOI: 10.1016/j.ebiom.2022.104322] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 09/09/2022] [Accepted: 10/10/2022] [Indexed: 11/06/2022] Open
Abstract
Background This exploratory study investigated four repurposed anti-infective drug regimens in outpatients with COVID-19. Methods This phase 2, single centre, randomised, open-label, clinical trial was conducted in South Africa between 3rd September 2020 and 23rd August 2021. Symptomatic outpatients aged 18–65 years, with RT-PCR confirmed SARS-CoV-2 infection were computer randomised (1:1:1:1:1) to standard-of-care (SOC) with paracetamol, or SOC plus artesunate-amodiaquine (ASAQ), pyronaridine-artesunate (PA), favipiravir plus nitazoxanide (FPV + NTZ), or sofosbuvir-daclatasvir (SOF-DCV). The primary endpoint was the incidence of viral clearance, i.e., the proportion of patients with a negative SARS-CoV-2 RT-PCR on day 7, compared to SOC using a log-binomial model in the modified intention-to-treat (mITT) population. Findings The mITT population included 186 patients: mean age (SD) 34.9 (10.3) years, body weight 78.2 (17.1) kg. Day 7 SARS-CoV-2 clearance rates (n/N; risk ratio [95% CI]) were: SOC 34.2% (13/38), ASAQ 38.5% (15/39; 0.80 [0.44, 1.47]), PA 30.3% (10/33; 0.69 [0.37, 1.29]), FPV + NTZ 27.0% (10/37; 0.60 [0.31, 1.18]) and SOF-DCV 23.5% (8/34; 0.47 [0.22, 1.00]). Three lower respiratory tract infections occurred (PA 6.1% [2/33]; SOF-DCV 2.9% [1/34]); two required hospitalisation (PA, SOF-DCV). There were no deaths. Adverse events occurred in 55.3% (105/190) of patients, including one serious adverse event (pancytopenia; FPV + NTZ). Interpretation There was no statistical difference in viral clearance for any regimen compared to SOC. All treatments were well tolerated.

[PMID: 36388934 PMCID: PMC9640910 DOI: 10.3389/fmed.2022.1001876] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 09/22/2022] [Indexed: 12/20/2023] Open
Abstract
BACKGROUND Different levels of evidence related to the variable responses of individuals to drug treatment have been reported in various pharmacogenomic (PGx) databases. Identification of gene-drug pairs with strong association evidence can be helpful in prioritizing the implementation of PGx guidelines and focusing on a gene panel. This study aimed to determine the pharmacogenes with the highest evidence-based association and to indicate their involvement in drug-gene interactions. METHODOLOGY The publicly available datasets CPIC, DPWG, and PharmGKB were selected to determine the pharmacogenes with the highest drug outcome associations. The upper two levels of evidence rated by the three scoring methods were specified (levels A-B in CPIC, 3-4 in DPWG, or 1-2 levels in PharmGKB). The identified pharmacogenes were further ranked in this study based on the number of medications they interacted with. RESULTS Fifty pharmacogenes, with high to moderately high evidence of associations with drug response alterations, with potential influence on the therapeutic and/or toxicity outcomes of 152 drugs were identified. CYP2D6, CYP2C9, CYP2C19, G6PD, HLA-B, SLCO1B1, CACNA1S, RYR1, MT-RNR1, and IFNL4 are the top 10 pharmacogenes, where each is predicted to impact patients' responses to ≥5 drugs. CONCLUSION This study identified the most important pharmacogenes based on the highest-ranked association evidence and their frequency of involvement in affecting multiple drugs. The obtained data is useful for customizing a gene panel for PGx testing. Identifying the strength of scientific evidence supporting drug-gene interactions aids drug prescribers in making the best clinical decision.

Abstract
Efforts toward eradicating the Hepatitis C virus (HCV) have advanced rapidly, due to the development of direct-acting antivirals (DAAs), especially with the appearance of pan-genotypic combinations. Real-world studies, in particular, have verified the efficacy and safety of DAA combinations documented in registration trials. This review documents the results of using DAA combinations in real-life settings in everyday clinical practice in Egypt, the country with the highest prevalence of HCV. The significant number of treated patients in Egypt, which exceeded four million allowed tremendous data about the results of HCV management in real-life settings for different treatment regimens and disease conditions. DAA combinations have resulted in high sustained virologic response rates (SVR12) and few adverse reactions in real-life settings. SVR12 rates ranged from 90% to 100%, depending on the combination of drugs used, the HCV genotype, and the stage of liver disease. Most adverse reactions reported in real-world settings were mild and resulted in treatment discontinuation in only a minority of cases. Data from real-life studies covered most aspects of HCV management that were lacking after initial approval studies. More research is needed to tailor treatment and produce generic HCV combinations to overcome the residual limitations of the currently available DAAs.
