Introduction Non-alcoholic fatty liver disease (NAFLD) has become a widespread cause of chronic liver disease, ranging from simple steatosis to severe conditions like non-alcoholic steatohepatitis (NASH) and cirrhosis. Despite its similarity to alcohol-induced liver damage, NAFLD affects individuals with no significant alcohol consumption. This study explores the association between NAFLD, bone mineral density (BMD), insulin resistance, and subclinical inflammation, focusing on the Asian Indian population. The primary objective was to investigate the relationship between NAFLD and BMD, insulin levels, and markers of subclinical inflammation, hypothesizing that patients with NAFLD exhibit lower BMD, possibly linked to insulin resistance and inflammation. Methodology A cross-sectional study with 100 subjects aged 18-50 years (50 cases with NAFLD and 50 controls) was conducted. Exclusion criteria included excessive alcohol consumption, drug-induced fatty liver, severe organ dysfunction, infections, pregnancy, and acute or chronic illness. Data were collected through clinical examinations, anthropometric measurements, biochemical investigations, ultrasound diagnosis of NAFLD, and dual-energy X-ray absorptiometry (DEXA) scans for BMD assessment. Statistical analysis employed the chi-squared tests, t-tests, and Wilcoxon rank-sum tests. Results NAFLD patients had higher body mass index (BMI), waist-to-hip ratio, and markers of insulin resistance and inflammation compared to non-NAFLD controls. DEXA scans revealed significantly lower BMD in NAFLD cases, along with a higher prevalence of osteopenia. Positive correlations were observed between BMD and insulin resistance. The study contributes to understanding the link between NAFLD and lower BMD in the Asian Indian population, emphasizing the impact of insulin resistance and inflammation on bone health. The literature review supports the relevance of exploring NAFLD as an independent risk factor for low BMD. Conclusion This case-control study underscores the significant association between NAFLD and lower BMD in the Asian Indian population. Despite limitations, the findings highlight the importance of further research with larger samples and comprehensive assessments to elucidate the interplay between NAFLD, metabolic factors, and bone health.
引言 非酒精性脂肪性肝病(NAFLD)已成为慢性肝病的一个普遍病因,范围从单纯性脂肪变性到诸如非酒精性脂肪性肝炎(NASH)和肝硬化等严重病症。尽管NAFLD与酒精性肝损伤相似,但它影响的是没有大量饮酒的个体。本研究探讨了NAFLD、骨密度(BMD)、胰岛素抵抗和亚临床炎症之间的关联,重点关注亚洲印度人群。主要目的是研究NAFLD与BMD、胰岛素水平及亚临床炎症标志物之间的关系,假设NAFLD患者的BMD较低,这可能与胰岛素抵抗和炎症有关。
方法 对100名年龄在18至50岁之间的受试者(50例NAFLD患者和50例对照)进行了一项横断面研究。排除标准包括过量饮酒、药物性脂肪肝、严重器官功能障碍、感染、妊娠以及急性或慢性疾病。通过临床检查、人体测量、生化检测、NAFLD的超声诊断以及用于BMD评估的双能X线吸收法(DEXA)扫描收集数据。统计分析采用卡方检验、t检验和Wilcoxon秩和检验。
结果 与非NAFLD对照组相比,NAFLD患者的体重指数(BMI)、腰臀比以及胰岛素抵抗和炎症标志物更高。DEXA扫描显示NAFLD病例的BMD显著降低,且骨质减少的患病率更高。观察到BMD与胰岛素抵抗之间存在正相关。该研究有助于理解亚洲印度人群中NAFLD与较低BMD之间的联系,强调了胰岛素抵抗和炎症对骨骼健康的影响。文献综述支持将NAFLD作为低BMD的独立危险因素进行探索的相关性。
结论 这项病例对照研究强调了亚洲印度人群中NAFLD与较低BMD之间的显著关联。尽管存在局限性,但研究结果突出了进一步开展更大样本和全面评估研究以阐明NAFLD、代谢因素和骨骼健康之间相互作用的重要性。
