P1024INFLUENCE OF NON-ALCOHOLIC FATTY LIVER DISEASE IN THE EVOLUTION OF RENAL FUNCTION IN DIABETIC PATIENTS
Abstract Background and Aims Nowadays, there is growing evidence that non-alcoholic fatty liver disease (NAFLD) may be associated with renal impairment and have an impact on the evolution of renal function in patients with type 2 diabetes mellitus (DM). Our aim was to compare the effect on renal function and proteinuria in patients with type 2 DM according to the presence of NAFLD. Method Retrospective and observational study, including patients with type 2 DM, < 70 years of age and with estimated glomerular filtration rate (eGFR) > 30 ml/min/1,73 m2. NAFLD was defined with the presence of compatible ultrasonography and/or presence of fibrosis using NAFLD score. Metabolic syndrome (MSd) was defined as: obesity (body mass index (BMI) > 30 kg/m2), hypertension and dyslipidaemia. Patients were classified according to the presence or absence of NAFLD. We analysed different clinical and analytical variables along the follow up. Results A total of 71 patients were included (66% males) with mean age of 57.4 ± 7.8 years. The median evolution of type 2 DM was 72.2 months (34.7 - 125.5 months) and 90.1% of the patients were treated with renin-angiotensin blockade. When comparing patients with (group 1, n=38) and without (group 2, n=33) NAFLD at the beginning of this study, we found no significant difference in eGFR (80.2 ± 40.4 ml/min vs 71.4 ± 31.8 ml/min), proteinuria (1.4 ± 2.7 g/24h vs 0.8 ± 1.0 g/24h) and glycated haemoglobin (6.8 ± 1.4% vs 7.2 ± 1.6%). On the other hand, we found significant difference in the presence of higher BMI (33.8 vs 29.3 kg/m2; .001) and presence of MSd (67.7 vs 32.3%; .03) in those patients with NAFLD. After a mean follow-up time of 74 months, we found significant differences in the loss of eFGR (-33.8 vs -13.9 ml/min; .003), but no difference in increase of proteinuria. We found an increase in incidence of chronic kidney disease in group 1 (50%) vs group 2 (10.5%). There were no differences in the need to initiate renal replacement therapy or all-cause mortality. Conclusion NAFLD in type 2 DM caused a mayor decline in renal function. We should, therefore, take into consideration the presence of NALFD and the presence of MSd to optimise treatment of associated risk factors.
