RENAL INJURY AND METABOLIC DYSFUNCTION-ASSOCIATED STEATOTIC LIVER DISEASE IN PATIENTS WITH OBESITY
ABSTRACT Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the most prevalent cause of chronic hepatic disease worldwide. Recently, the association between MASLD and renal injury has emerged as an additional factor impacting the clinical course of MASLD. Obj...

| Summary: | ABSTRACT Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the most prevalent cause of chronic hepatic disease worldwide. Recently, the association between MASLD and renal injury has emerged as an additional factor impacting the clinical course of MASLD. Objective: The present study evaluated the clinical association in patients with obesity. Methods: This study enrolled patients classified as having obesity class II and III (BMI >35 kg/m2) and MASLD from an obesity surgical treatment center. The diagnosis criteria for MASLD included the presence of hepatic steatosis as indicated by histology or imaging assessments. We use Fibrosis-4 (FIB-4) and NAFLD fibrosis score (NSF) to assess and determine the presence of liver fibrosis. The glomerular filtration rate (GRF) was determined using CKD-EPI (chronic kidney disease epidemiology collaboration) equation, with GFR levels ≥90 and <120 mL/min/1,73 m2 considered within the normal range. Results: The study comprised a total of 560 individuals with obesity grade II and III, 325 individuals with MASLD. Among these, 422 (75.4%) patients were female, and the mean age was 36±10 years. Systemic arterial hypertension (SAH) was present in 162 (41.1%) patients, and 218 (42.8 %) were diagnosed with type 2 Diabetes Mellitus (T2DM). A total of 286 individuals (51.1%) had a GFR below 114 mL/min, with 183 (64%) of them exhibiting a higher degree of liver fibrosis, as indicated by FIB-4 >0.54. Conclusion: In patients with obesity classified as grades II and III, age emerged as the primary determinant leading to decline in GFR. Furthermore, glomerular hyperfiltration could be an early sign of progression to chronic kidney disease. Nonetheless, the progression of hepatic fibrosis could also be a significant factor contributing to impaired renal function. |
