RESUMO

BACKGROUND AND AIMS: Obeticholic acid (OCA) is a farnesoid X receptor agonist used in primary biliary cholangitis (PBC) treatment. Recent studies have expanded OCA use for NASH treatment and results from phase 3 clinical trial have shown beneficial reduction of ≥1 stage of fibrosis with no NASH worsening. However, safety concerns still preside, thus we systematically examine the safety profile of OCA in chronic liver disease. MATERIALS AND METHODS: A search was conducted in Medline and Embase databases for OCA randomized controlled trials in chronic liver disease. Binary events were pooled with Paule-Mandel random effects model and proportional events were examined in a generalized linear mixed model with Clopper-Pearson intervals. RESULTS: A total of 8 studies and 1878 patients were analyzed. There was a 75% [risk ratio (RR): 1.75, 95% CI: 1.43-2.15, p < 0.01] increased pruritis risk. OCA increased constipation incidence (RR: 1.88, 95% CI: 1.45-2.43, p < 0.01), decreased diarrhea (RR: 0.62, 95% CI: 0.50-0.77, p < 0.01), and increased development of hyperlipidemia (RR: 2.69, 95% CI: 1.85-3.92, p < 0.01) relative to placebo. Sensitivity analysis in NASH-only studies found a dose-dependent effect with pruritis which increases to RR: 3.07 (95% CI: 1.74-5.41) at 25 mg. However, up to 9.98% (95% CI: 5.01%-18.89%) of NAFLD patients with placebo similarly experience pruritis events. Overall, 16.55% (95% CI: 6.47%-36.24%) of patients with NAFLD on OCA experienced pruritis. There was no significant increase in cardiovascular events. CONCLUSIONS: OCA may represent the first pharmacological treatment approved for NASH. However, pruritis, constipation, diarrhea, and hyperlipidemia were major events with evident dose-dependent effect that affect tolerability in NASH. Future long-term studies for longitudinal safety events are required.

RESUMO

BACKGROUND: Emerging data suggest that statins, aspirin and metformin may protect against hepatocellular carcinoma (HCC) development. However, prior meta-analyses were limited by heterogeneity and inclusion of studies without adequate adjustment for baseline risks. AIM: To examine by an updated meta-analysis the association between these medications and HCC risk. METHODS: Medline and Embase databases were searched from inception to March 2022 for studies that balanced baseline risks between study groups via propensity score matching or inverse probability of treatment weighting, that reported the impact of statins, aspirin or metformin on HCC risk. Multivariable-adjusted hazard ratios (HRs) for HCC were pooled using a random effects model. RESULTS: Statin use was associated with reduced HCC risk overall (HR: 0.52; 95% CI: 0.37-0.72) (10 studies, 1,774,476), and in subgroup analyses for cirrhosis, hepatitis B/C, non-alcoholic fatty liver disease, studies accounting for concurrent aspirin and metformin consumption and lipophilic statins. Aspirin use was associated with reduced HCC risk overall (HR: 0.48; 95% CI: 0.27-0.87) (11 studies, 2,190,285 patients) but not in studies accounting for concurrent statin and metformin use. Metformin use was not associated with reduced HCC risk overall (HR: 0.57; 95% CI: 0.31-1.06) (3 studies, 125,458 patients). Most analyses had moderate/substantial heterogeneity, except in follow-up <60 months for aspirin (I2  = 0%). CONCLUSION: Although statin and aspirin use were associated with reduced HCC risk, only statin use was significant in subgroup analyses accounting for concurrent medications. Metformin use was not associated with reduced HCC risk. These data have implications for future clinical trial design.
