AimsTo analyze the efficacy and safety of sofosbuvir (SOF)-based regimens in Thai patients with chronic hepatitis C virus infection who had pre-existing significant liver fibrosis. Patients and methodsThis was a retrospective cohort study, conducted between 1 June 2018 and 31 May 2019 at Rajavithi Hospital, Bangkok, Thailand. All patients completed 12 weeks of SOF-based regimens and had follow-up for at least 12 weeks after therapy discontinuation. The primary outcome was sustained virological response (SVR) 12 weeks after the end of therapy. ResultA total of 185 patients were included, with 52, 63 and 70 taking SOF+Ledipasvir (SOF +LDV), SOF+LDV+ribavirin (RBV) and SOF+Pegylated interferon (Peg-IFN)+RBV (SOF +Peg-IFN+RBV) respectively. Genotype (GT) 1 was predominant at 40.0%, followed by GT3 at 37.8%, and GT6 at 22.2%. Overall 95.1% of patients in this study achieved SVR (n = 176/185), and the only factor associated with SVR was HCV genotype (p = 0.001). GT6 patients had lower SVR rates compared to GT1 and GT3 patients (82.9%, 98.6%, and 98.6% respectively) while there was no association between SVR and other factors (p >0.05) such as gender, age, BMI, underlying cirrhosis, baseline HCV viral load, or prior treatment history. No serious adverse events were reported in the present study.
Aims. To describe the prevalence of hepatic steatosis using a controlled attenuation parameter (CAP) and to identify the determinants associated with steatosis in Thai chronic hepatitis C patients. Patients and Methods. An observational study was conducted among consecutive chronic hepatitis C patients who underwent vibration-controlled transient elastography (VCTE, FibroScan®) with CAP and followed up at Rajavithi Hospital, Bangkok, Thailand, between June 2018 and May 2019. Hepatic steatosis (i.e., steatosis grades S1-3) was defined by the CAP cutoff value of ≥248 (dB/m). VCTE with CAP assessments and medical records were retrospectively reviewed, and the prevalence and determinants of hepatic steatosis were analyzed. Results. A total of 197 eligible patients, of whom 127 (64.5%) were male, were included. The mean age was 54.52 years (SD 9.49 years), and 41.1% of subjects had a body mass index ≥ 25 . The prevalence of hepatic steatosis was 26.9%. The mean liver stiffness measurement (LSM) was 21.50 kPa (SD 15.58 kPa), and 61.9% of the study population had cirrhosis, which was defined as LSM ≥ 12.5 kPa. Genotype (GT) 3 was predominant at 40.1%, followed by GT1 at 38.1% and GT6 at 21.8%. The median serum hepatitis C virus viral load was 1,100,000 IU/mL (range 5,824-20,436,840). The significant determinants of hepatic steatosis were obesity (aOR 8.58 (95% CI: 3.41-21.54)) and diabetes mellitus (aOR 3.30 (95% CI: 1.24-8.78)). Conclusion. A large proportion of these Thai chronic hepatitis C patients (26.9%) had hepatic steatosis, which was strongly associated with host metabolic factors, e.g., obesity ( BMI ≥ 25 ) and diabetes mellitus. These cofactors contributed to the progression of liver disease to cirrhosis and required concurrent management with antiviral therapy.
Aims To describe the prevalence of significant liver fibrosis by ultrasound-based vibration-controlled transient elastography (VCTE; FibroScan®) and to identify the determinants of significant liver fibrosis in Thai chronic hepatitis B patients. Methods A cross-sectional study of consecutive chronic hepatitis B patients performed VCTE and followed up at Rajavithi Hospital, Bangkok, Thailand, was conducted between 1 January, 2013, and 31 December, 2016. Liver fibrosis was defined as minimal (METAVIR F0-1) by VCTE < 7.2 kPa and significant (METAVIR F2-4) by VCTE ≥ 7.2 kPa. VCTE assessments and medical records were retrospectively reviewed. The prevalence and determinants of significant liver fibrosis were analyzed. Results A total of 206 eligible patients were included; 120 patients (58.3%) were female. The mean age was 50 years (SD 12.4 years), and 32.5% had a body mass index ≥ 25. The prevalences of minimal (F 0-1) and significant fibrosis (F2-4) were 74.3% and 25.7%, respectively. The prevalence of hepatitis B e antigen negative (HBeAg -ve) was 83%. The median serum hepatitis B virus viral load was 4,340 IU/mL (range 20-271,883,036). Significant determinants of significant fibrosis (F2-4) were male gender (aOR 3.24 [95%CI: 1.36-7.72]) and high aspartate transaminase (AST) level (aOR 5.71 [95%CI: 2.03-16.04]). Conclusion Around one-quarter of the Thai patients with chronic viral hepatitis B had significant liver disease defined by VCTE, requiring further evaluation for specific treatment for hepatitis B virus. Determinants of significant liver fibrosis were male gender and high AST level.
