Abstract

BACKGROUND: Recent studies indicate that accumulation of adipose tissue in various organs such as liver and kidney may contribute to the pathophysiology of metabolic syndrome. We aim to investigate the association between kidney and liver adipose tissue accumulation, assessed by the magnetic resonance imaging (MRI) proton density fat fraction technique, along with its relation to clinical and biochemical parameters. METHODS: We included 51 volunteers with phenotypical features of metabolic syndrome (mean age = 34 years, mean body-mass index = 26.4 kg/m) in our study in which liver and kidney adipose tissue accumulation was assessed via MRI-proton density fat fraction along with multiple other clinical and biochemical parameters such as estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio, serum lipid profile, liver function tests and body-mass index (BMI). RESULTS: Our results from the univariate linear regression analysis indicate that both the kidney and liver scores were positively correlated with markers such as BMI, urine albumin-to-creatinine ratio, triglycerides (p < 0.001) and negatively correlated with eGFR (p < 0.05). In multivariate analysis, urine albumin-to-creatinine ratio (p < 0.05), triglycerides (p < 0.01), eGFR (p < 0.05) and BMI (p < 0.001) were found to be independently associated with kidney and liver fat accumulation, respectively (R = 0.64; R = 0.89). There was also a positive correlation between kidney and liver fat accumulation. CONCLUSION: We have found a significant association between adipose tissue accumulation in liver and kidney and the parameters of metabolic syndrome. Moreover, the presence of a strong association between kidney and liver fat accumulation and kidney function parameters such as urine albumin-to-creatinine ratio and eGFR may be an indicator of the clinical significance of parenchymal fat accumulation.

摘要

背景:最近的研究表明,肝脏和肾脏等各种器官的脂肪堆积可能导致代谢综合征的病理生理学变化。我们旨在通过磁共振成像(MRI)质子密度脂肪分数技术评估肝和肾脂肪组织的积累,并探讨其与临床和生化参数的关系。

方法:我们纳入了 51 名具有代谢综合征表型特征的志愿者(平均年龄 34 岁,平均体重指数 26.4 kg/m),通过 MRI 质子密度脂肪分数评估肝和肾脂肪组织的积累,以及其他多个临床和生化参数,如估算肾小球滤过率(eGFR)、尿白蛋白/肌酐比值、血脂谱、肝功能检查和体重指数(BMI)。

结果:我们的单变量线性回归分析结果表明,肝和肾评分与 BMI、尿白蛋白/肌酐比值、甘油三酯等标志物呈正相关(p<0.001),与 eGFR 呈负相关(p<0.05)。在多变量分析中,尿白蛋白/肌酐比值(p<0.05)、甘油三酯(p<0.01)、eGFR(p<0.05)和 BMI(p<0.001)分别与肝和肾脂肪积累独立相关(R=0.64;R=0.89)。此外,肝和肾脂肪积累之间也存在正相关关系。

结论:我们发现肝和肾脂肪堆积与代谢综合征的参数之间存在显著相关性。此外,肾和肝脂肪堆积与尿白蛋白/肌酐比值和 eGFR 等肾功能参数之间存在较强的相关性,这可能是实质脂肪堆积的临床意义的一个指标。
