Key Takeaway
Consider energy modulators for metabolic parameters and gut microbiota modulators for BMI in pediatric NAFLD.

This Bayesian network meta-analysis examined pharmacological interventions for pediatric nonalcoholic fatty liver disease (NAFLD). The study included 1,582 patients confirmed by ultrasound or biopsy and categorized drugs into energy, inflammation, fibrosis, and gut microbiota modulators. The primary outcome was improvement in hepatic steatosis, with secondary outcomes including liver enzymes, lipid profiles, and metabolic parameters.

Energy modulators demonstrated greater effectiveness than placebo for improving hepatic steatosis, with a relative risk of 3.32 and a 95% credible interval of 1.52–8.26. Inflammation modulators also showed superiority over placebo with a relative risk of 2.33 and a 95% credible interval of 1.09–5.27. Gut microbiota modulators exhibited the highest relative risk at 4.60 with a 95% credible interval of 1.42–15.69.

For specific metabolic outcomes, energy modulators were identified as optimal agents for reducing serum ALT levels, decreasing triglyceride contents, increasing HDL-C levels, and improving HOMA-IR. The SUCRA scores for these outcomes were 86.20%, 91.77%, 94.29%, and 88.01% respectively. Conversely, gut microbiota modulators were the most effective agents for reducing BMI, achieving a SUCRA score of 96.25%.

The authors note that adverse events, serious adverse events, discontinuations, and tolerability were not reported in the source data. This systematic review serves as a valuable guide for optimizing drug development and selecting agents for combination therapies. Clinicians should interpret these pooled estimates with caution, recognizing that the evidence derives from a Bayesian network meta-analysis rather than a single randomized trial.

ObjectiveNon-alcoholic fatty liver disease (NAFLD) is now the leading cause of chronic liver disease in children and adolescents, and there is no defined treatment for this condition. A network meta-analysis (NMA) was conducted to examine the comparative efficacy of specific mechanism pathways of drugs to achieve improvements in hepatic steatosis in pediatric NAFLD patients.MethodsRandomized controlled trials regarding pharmacological interventions for pediatric NAFLD patients were obtained. Treatments were classified into energy, inflammation, fibrosis, and gut microbiota modulators. The primary outcome was an improvement in hepatic steatosis, and the secondary outcomes included changes in liver enzymes, lipid profile, and metabolic parameters. Direct meta-analysis and NMA with Bayesian random effects were performed for the extracted data, respectively.ResultsNineteen RCTs that met the eligibility criteria were identified for this analysis, involving a total of 1,582 pediatric NAFLD patients confirmed by ultrasound or biopsy. Treatment modulating energy (Relative risk (RR): 3.32; 95% Credible intervals (CrI): 1.52–8.26; P < 0.05), inflammation (RR: 2.33; 95% CrI: 1.09–5.27; P < 0.05) and gut microbiota (RR: 4.60; 95% CrI: 1.42–15.69; P < 0.05) were all more effective than placebo in improving hepatic steatosis. Further analysis of secondary outcomes indicated that treatments modulating energy were the optimal agents for reducing serum alanine aminotransferase (ALT) levels (surface under the cumulative ranking curve (SUCRA) = 86.20%), decreasing triglyceride (TG) contents (SUCRA = 91.77%), increasing high-density lipoprotein cholesterol (HDL-C) levels (SUCRA = 94.29%), and improving homeostasis model assessment of insulin resistance (HOMA-IR) (SUCRA = 88.01%). Treatments modulating gut microbiota were the most effective agents for reducing BMI (SUCRA = 96.25%) in pediatric NAFLD patients.ConclusionThis NMA revealed the relative advantages of drugs that modulate energy in the treatment of pediatric NAFLD, potentially serving as a valuable guide for optimizing drug development and selecting agents for combination therapies.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier [CRD42023417431].
