Cost-utility analysis of direct-acting antivirals for treatment of chronic hepatitis C genotype 1 and 6 in Vietnam

Objective: Very few cost-utility analyses have either evaluated direct-acting antivirals (DAAs) on hepatitis C virus (HCV) genotype 6 patients or undertaken societal perspective. Recently, DAAs have been introduced into the Vietnamese health insurance drug list for chronic hepatitis C (CHC) treatment without empirical cost-effectiveness evidence. This study was conducted to generate these data on DAAs among CHC patients with genotypes 1 and 6 in Vietnam. Methods: A hybrid decision-tree and Markov model was employed to compare costs and quality-adjusted life-years (QALYs) of available DAAs, including (1) sofosbuvir/ledipasvir, (2) sofosbuvir/velpatasvir, and (3) sofosbuvir plus daclatasvir, with pegylated-interferon plus ribavirin (PR). Primary data collection was conducted in Vietnam to identify costs and utility values. Incremental cost-effectiveness ratios were estimated from societal and payer perspectives. Uncertainty and scenario analyses and value of information analyses were performed. Results: All DAAs were cost-saving as compared with PR in CHC patients with genotypes 1 and 6 in Vietnam, and sofosbuvir/velpatasvir was the most cost-saving regimen, from both societal and payer perspectives. From the societal perspective, DAAs were associated with the increment of quality-adjusted life-years by 1.33 to 1.35 and decrement of costs by $6519 to$7246. Uncertainty and scenario analyses confirmed the robustness of base-case results, whereas the value of information analyses suggested the need for further research on relative treatment efficacies among DAA regimens. Conclusions: Allocating resources for DAA treatment for HCV genotype 1 and 6 is surely a rewarding public health investment in Vietnam. It is recommended that the government rapidly scale up treatment and enable financial accessibility for HCV patients

Outcomes of direct-acting antivirals in patients with HCV decompensated cirrhosis: a systematic review and meta-analysis

BackgroundDirect-acting antivirals (DAA) are effective for chronic hepatitis C virus (HCV) treatment. However, their impact on overall survival (OS), hepatocellular carcinoma (HCC) occurrence, HCC-free survival, and liver function in patients with HCV decompensated cirrhosis remains uncertain. This study aimed to evaluate the effects of DAA treatment on this population.MethodsStudies were identified by searching the MEDLINE, SCOPUS, and CENTRAL databases. OS and HCC-free survival probabilities and time data were extracted from Kaplan-Meier curves. A one-stage meta-analysis using parametric Weibull regression was conducted to estimate the relative treatment effects of DAA vs. no DAA. The primary outcome was the OS rate. The secondary outcomes were HCC-free survival, HCC occurrence rate, and improvement in the Model for End-stage Liver Disease (MELD) score.ResultsEight cohorts comprising 3,430 participants (2,603 in the DAA group and 1,999 in the no-DAA group) were included. The OS probabilities at 12 and 24 months were 95 and 90% for the DAA group, respectively, compared with 89 and 80% in the no-DAA group, respectively. Hazard ratio (HR) was 0.48 (95% confidence interval (CI): 0.39, 0.60; p < 0.001). The HCC-free survival probabilities at 12 and 24 months were 96 and 90%, respectively, in the former, and 94 and 85%, respectively, in the latter. The HR of HCC occurrence was 0.72 (95% CI: 0.52, 1.00; p = 0.05), which suggests that DAA treatment in decompensated cirrhosis may lead to a 28% lower risk of HCC occurrence. The mean MELD score difference was −7.75 (95% CI: −14.52, −0.98; p = 0.02).ConclusionImprovement in OS and MELD score is a long-term benefit of DAA treatment in patients with HCV decompensated cirrhosis, with a marginal effect of the treatment on HCC development

Nucleotide Analogue-Related Proximal Renal Tubular Dysfunction during Long-Term Treatment of Chronic Hepatitis B: A Cross-Sectional Study

Background. There have been few reports of nucleotide analogue-related renal tubular dysfunction (RTD) in CHB patients. We assessed the prevalence and presentation of nucleotide analogue-related proximal RTD. Methods. A cross-sectional study was performed in CHB patients taking nucleotide analogues. Inclusion criteria were patients who were on adefovir or tenofovir as mono- or add-on therapy with lamivudine (LAM) >1 year. Serum and urine were collected. Fractional excretion of phosphate (FEPO4), uric acid (FEUA), and potassium was calculated. Renal losses were defined based on the criteria: protein (24-hour urine protein >150 mg), glucose (glycosuria with normoglycemia), phosphate (FEPO4 >18%), uric acid (FEUA >15%), potassium (renal potassium losses with hypokalemia), and bicarbonate (normal gap acidosis). Subclinical and overt proximal RTD were defined when 2 and ≥3 criteria presented. Results. Ninety-two patients were enrolled. The mean duration of nucleotide analogue taking was 55.1±29.6 months. Proximal RTD was found in 24 (26.1%) patients (subclinical 15 (16.3%) and overt 9 (9.8%)). The severity of RTD was associated with the duration of nucleotide analogue (P=0.01). Conclusions. The prevalence of proximal RTD in CHB patients taking nucleotide analogues was 26%. The severity of RTD was associated with the treatment duration. Comprehensive testing is necessary for early detecting nucleotide analogue-related nephrotoxicity

A Literature Review on Regulations Enforced to Reduce Adolescents’ Use of E-Cigarette in Thailand

In Thailand, increasing use of e-cigarettes among adolescents poses a significant public health concern. This review demonstrated the multifaceted issues of the problem by exploring the origin of e-cigarettes, factors impacting the broad use of vapes among teenagers, and the guidelines/laws of vaping from government authorities across Asian and Western nations. This study examined the health risks associated with e-cigarette use, dispelled misconceptions regarding public safety, and highlighted the existing treatment programs. Furthermore, the report encompasses frameworks that control teenagers’ e-cigarette consumption. Here, we present viewpoints on the situation in Thailand, which are now compared to global experiences. This highlights the urgent need for strict laws to curb the increasing trend in e-cigarette use among adolescents. In this study, the strategy to reduce adolescents’ vaping use is proposed with an “ECIG” approach which comprises of Establish e-cigarette prohibition law for adolescents, Control retailers from selling e-cigarette, Individuals’ understanding of its negative impact and Guardian’s supervision

Optimal resting heart rate and ascites‐related death in patients with cirrhosis and ascites using nonselective beta‐blockers (ORCA)

Abstract Nonselective beta‐blockers (NSBBs) may exacerbate ascites by impairing cardiac function. This study evaluated the impact of achieving a heart rate target of 55–60 beats per minute (bpm) on ascites‐related death and complications from worsening ascites in patients with cirrhosis and diuretic‐responsive ascites using NSBBs. A retrospective study was conducted at the Faculty of Medicine Ramathibodi Hospital, Mahidol University (2012–2022) and analyzed patients with cirrhosis and diuretic‐responsive ascites using NSBBs (propranolol/carvedilol) for variceal bleeding prophylaxis. The outcomes were incidence of ascites‐related death and complications from worsening ascites, comparing the achievable target group (heart rate 55–60 bpm) and the unachievable target group (heart rate >60 bpm). A total of 206 patients were included in the study, with a median follow‐up time of 20 months. The patients were divided into an achievable target group (n = 75, median heart rate = 58.0 bpm) and an unachievable target group (n = 131, median heart rate = 73.6 bpm). Propranolol was the most used NSBB (95.1%). The adjusted hazard ratio (HR) for ascites‐related death from spontaneous bacterial peritonitis (SBP) or refractory ascites (RA) or hepatorenal syndrome (HRS) or hepatic encephalopathy (HE) showed no difference between the groups (adjusted HR 0.59 [0.23–1.54]; p = 0.28). Additionally, no significant difference was found in the incidence of complications between groups, including SBP, RA, HRS, and HE. Achieving a heart rate target of 55–60 bpm with NSBBs for variceal bleeding prophylaxis is safe in patients with diuretic‐responsive ascites and cirrhosis
