Abstract
AbstractObjectiveTo investigate the effects of metabolic associated fatty liver disease (MAFLD) on chronic kidney disease (CKD) and abnormal albuminuria and the interaction between MAFLD and diabetes on abnormal albuminuria.MethodsData of participants in the American 2017–2018 National Health and Nutrition Examination Survey were analyzed. Hepatic steatosis was defined as median controlled attenuation parameter ≥248 dB/m, which was measured by ultrasound transient elastography. MAFLD was defined by evidence of hepatic steatosis on ultrasound in addition to any metabolic dysregulation. Hepatic fibrosis was detected by FibroScan and quantified by parameter of stiffness (E). Hepatic fibrosis was defined as E ≥ 9.7 kPa. As component of CKD, reduced estimated glomerular filtration rate (eGFR) was defined as<60 mL/min/1.73 m2 and abnormal albuminuria was defined as urinary albumin‐to‐creatinine ratio ≥ 30 mg/g.ResultsData pertaining to 5119 participants were included in the analysis, with 40.6% hepatic normal, 52.1% MAFLD, and 7.2% hepatic fibrosis. Multivariable regression analyses showed that for abnormal albuminuria, the odds ratio (OR) was 0.82 (0.65–1.04) for MAFLD group and 1.73 (1.14.–,2.63) for hepatic fibrosis group, both taking the hepatic healthy group as reference. As for reduced eGFR, the OR was 0.68 (0.51–0.92) for MAFLD group and 0.93 (0.56–1.53) for hepatic fibrosis group. Diabetes was significantly related to greater risk of abnormal albuminuria (3.04 [2.70–3.42]) and reduced eGFR (1.53 [1.33–1.77]). With regard to the prevalence of abnormal albuminuria, the OR was 1.64 (1.03–2.60) for those with hepatic fibrosis only, 3.30 (2.80–3.89) for those with diabetes only, and 5.05 (3.30–7.72) for those with both two conditions. But there were neither additive interaction (relative excess risk due to interaction 0.56 [−1.41–.53], p = .577) nor multiplicative interaction (OR 0.81 [0.45–1.47], p = .492) between hepatic fibrosis and diabetes on the prevalence of abnormal albuminuria.ConclusionMAFLD with hepatic fibrosis is an independent risk factor for abnormal albuminuria, but it does not have interaction with diabetes on abnormal albuminuria.
