Sarcopenia and risk of nonalcoholic fatty liver disease: A meta-analysis.

ABSTRACT: Background/Aim:The association between sarcopenia and nonalcoholic fatty liver disease (NAFLD) has been suggested by recent epidemiological studies, although the results have been inconsistent. This meta-analysis was conducted to summarize all available data and estimate the risk of NAFLD among patients with sarcopenia. Materials and Methods:A comprehensive literature review was conducted using MEDLINE and EMBASE databases through November 2016 to identify all studies that compared the risk of NAFLD among patients with sarcopenia versus those without sarcopenia. Effect estimates from each study were extracted and combined using the random-effect, generic inverse variance method of DerSimonian and Laird. Results:Five cross-sectional studies with 27,804 participants met the eligibility criteria and were included in the meta-analysis. The risk of NAFLD in patients with sarcopenia was significantly higher than those without sarcopenia with the pooled odds ratio of 1.54 (95% confidence interval, 1.05-2.26). The statistical heterogeneity was high with an I2of 83%. Conclusions:A significantly increased risk of NAFLD among patients with sarcopenia was observed in this study.

Project description:Liver fibrosis is the most important predictor of mortality in nonalcoholic fatty liver disease (NAFLD). Quantitative risk of mortality by fibrosis stage has not been systematically evaluated. We aimed to quantify the fibrosis stage-specific risk of all-cause and liver-related mortality in NAFLD. Through a systematic review and meta-analysis, we identified five adult NAFLD cohort studies reporting fibrosis stage-specific mortality (0-4). Using fibrosis stage 0 as a reference population, fibrosis stage-specific mortality rate ratios (MRRs) with 95% confidence intervals (CIs) for all-cause and liver-related mortality were estimated. The study is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Included were 1,495 NAFLD patients with 17,452 patient years of follow-up. Compared to NAFLD patients with no fibrosis (stage 0), NAFLD patients with fibrosis were at an increased risk for all-cause mortality, and this risk increased with increases in the stage of fibrosis: stage 1, MRR = 1.58 (95% CI 1.19-2.11); stage 2, MRR = 2.52 (95% CI 1.85-3.42); stage 3, MRR = 3.48 (95% CI 2.51-4.83); and stage 4, MRR = 6.40 (95% CI 4.11-9.95). The results were more pronounced as the risk of liver-related mortality increased exponentially with each increase in the stage of fibrosis: stage 1, MRR = 1.41 (95% CI 0.17-11.95); stage 2, MRR = 9.57 (95% CI 1.67-54.93); stage 3, MRR = 16.69 (95% CI 2.92-95.36); and stage 4, MRR = 42.30 (95% CI 3.51-510.34). Limitations of the study include an inability to adjust for comorbid conditions or demographics known to impact fibrosis progression in NAFLD and the inclusion of patients with simple steatosis and nonalcoholic steatohepatitis without fibrosis in the reference comparison group.ConclusionThe risk of liver-related mortality increases exponentially with increase in fibrosis stage; these data have important implications in assessing the utility of each stage and benefits of regression of fibrosis from one stage to another.
