RESUMEN
Background: Bile acid malabsorption (BAM) is characterized by chronic watery diarrhea resulting from excessive bile acids in the feces. BAM is often an overlooked cause of chronic diarrhea, with its prevalence not being sufficiently researched. This review aimed to assess existing literature that explores diverse treatment strategies, to review the published studies that examine the various therapies for BAM patients, emphasizing their influence on clinical results. Methods: We conducted a comprehensive review of various databases, including PubMed, Scopus, Web of Science, Cochrane Database, and EMBASE. Our criteria for inclusion focused on randomized controlled studies (RCTs) that evaluated the effectiveness of different treatment options for patients with BAM. To rank the treatments, we adopted the frequentist approach through the "netrank" function of the network meta-analysis (NMA). Moreover, we utilized the "netsplit" function in the NMA to separate direct and indirect evidence. Our analysis was carried out using RStudio version 1.4.1717 (2009 - 2021 RStudio, Inc.), and we used the "netmeta" and "meta" packages for NMA. Results: We found seven relevant articles involving 213 participants, the average age being approximately 50 years, including 53 males and 92 females. Of the drugs examined, tropifexor was proved to be the most effective in raising the fibroblast growth factor 19 (FGF19) levels and reducing the 7 alpha-hydroxy-4-cholesten-3-one (C4) levels, compared to the placebo (mean difference (MD) = 335.30, 95% confidence interval (CI) (334.86, 335.74), MD = -24.60, 95% CI (-25.37, -23.83); respectively). Compared to colesevelam and the placebo, liraglutide was more efficient in decreasing fecal bile acid concentration (liraglutide; MD = -19, 95% CI (-37.61, -0.39)). Conclusions: Tropifexor has been identified as the most successful medication in mitigating BAM symptoms. To ensure more accurate results, there is a need for randomized controlled clinical trials that involve a larger participant pool.
RESUMEN
Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are prevalent conditions linked to obesity and metabolic disturbances, with potential complications such as cirrhosis and cardiovascular risks. This systematic review and meta-analysis aimed to evaluate the efficacy of pemafibrate, a drug targeting fat and sugar metabolism genes, in treating patients with MASLD/MASH. Methods: Databases such as MEDLINE, Web of Science, Cochrane Library, and Scopus were searched until September 2023 to identify relevant studies. Selected studies underwent a thorough quality assessment using tools like Risk of Bias 2 tool (ROB-2) and the National Institutes of Health (NIH) Quality Assessment Tools. Comprehensive meta-analysis software was used for statistical evaluations, with a focus on lipid profiles, liver function tests, and fibrosis measurements. Results: A total of 13 studies were included; 10 of them were included in the quantitative analysis. Our findings showed that pemafibrate significantly decreased low-density lipoprotein cholesterol (LDL-C) (effect size (ES) = -9.61 mg/dL, 95% confidence interval (CI): -14.15 to -5.08), increased high-density lipoprotein cholesterol (HDL-C) (ES = 3.15 mg/dL, 95% CI: 1.53 to 4.78), and reduced triglycerides (TG) (ES = -85.98 mg/dL, 95% CI: -96.61 to -75.36). Additionally, pemafibrate showed a marked reduction in liver enzyme levels, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP), with significant effect sizes and P values. For liver stiffness outcomes, pemafibrate decreased AST to platelet ratio index (APRI) (ES = -0.180, 95% CI: -0.221 to -0.138). Conclusions: Pemafibrate, with its enhanced efficacy and safety profile, presents as a pivotal agent in MASLD/MASH treatment. Its lipid-regulating properties, coupled with its beneficial effects on liver inflammation markers, position it as a potentially invaluable therapeutic option.
