Prevalence of Chronic Kidney Disease in Nonalcoholic Fatty Liver Disease Patients.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. It is not only associated with liver-related mortality and morbidity but is a multisystem disease that affects multiple extra-hepatic organ systems, such as the kidneys and cardiovascular system. Our study was conducted to evaluate the possible relationship between NAFLD and the risk of chronic kidney disease (CKD) development. This is a comparative cross-sectional study. The study was conducted on 100 patients who were diagnosed with NAFLD by abdominal ultrasound, CKD was diagnosed either by estimated glomerular filtration rate (eGFR) ≤60 mL/min/1.73 m2 or by the presence of albuminuria (albumin creatinine ratio >30 mg/g).These patients were classified into two groups, the CKD group and the non-CKD group, and the two groups were compared according to different parameters. The data were collected, presented, and statistically analyzed with the computer program IBM SPSS Statistics version 23. Among 100 NAFLD patients, there were 19 patients developed CKD diagnosed either by eGFR or by the presence of albuminuria. These CKD patients were older, have abdominal obesity, higher body mass index, higher cholesterol level, higher low-density lipoprotein level, higher triglycerides levels, higher systolic and diastolic blood pressure, and higher fatty liver index and a higher degree of fatty liver by ultrasound. Our current study suggests that NAFLD may be associated with a high risk of CKD.
