Title: Role of non-alcoholic fatty liver disease in the evolution of renal function in patients with diabetes mellitus.
Abstract: BACKGROUND: Increasing prevalence in type 2 diabetes mellitus (T2DM) have influenced in an increasing prevalence of chronic kidney disease (CKD). Little is known about the influence of non-alcoholic fatty liver disease (NAFLD) on progression of CKD. The aim of this study was to analyse the role of NAFLD and its severity in the progression of renal function in patients with T2DM. METHODS: Retrospective and observational study, including patients with T2DM and estimated glomerular filtration rate (eGFR) >30&#8201;ml/min/1,73m2. NAFLD was defined with presence of compatible ultrasonography and/or presence of fibrosis using NAFLD score. Patients were classified in three groups according to the NAFLD score; group 1 <-1.85, group 2 -1.85 to 0.18, and group 3&#8201;>&#8201;0.18. RESULTS: A total of 102 patients were included (67.6% males, median age 59 [53-64] years), with median time of T2DM evolution was 70 [39-131] months. Group 3 had lower eGFR (84.8&#8201; &#177; &#8201;40.4 vs 71.4&#8201; &#177; &#8201;30.6&#8201;ml/min/1.73m2; p&#8201;=&#8201;0.03) and higher proteinuria at baseline (0.56&#8201; &#177; &#8201;0.77 vs 1.59&#8201; &#177; &#8201;2.70&#8201;g/24h; p&#8201;=&#8201;0.05). After a follow-up time of 75.8&#8201; &#177; &#8201;23.9&#8201;months, group 3 had a significant decrease in eGFR (66.6&#8201; &#177; &#8201;33.3 vs 36.8&#8201; &#177; &#8201;23.1&#8201;ml/min/1.73m2; p&#8201;=&#8201;<0.01), and higher risk of CKD progression (OR 7.50; CI 95% 2.76-20.35; p&#8201;=&#8201;<0.001) defined as decrease in&#8201;>&#8201;50% eGFR. CONCLUSIONS: The presence of NAFLD with high-risk fibrosis confers higher risk of CKD progression in patients with T2DM. Therefore, NAFLD should be a risk factor evaluated in these patients to optimise treatment.
