Evaluation of Liver Enzymes in End-Stage Renal Disease Patients on the Renal Transplant-Waiting List in North-West of Iran

 Liver diseases, mainly hepatitis B and C, commonly occur in patients with end-stage renal diseases (ESRD). Alanine and aspartate aminotransferase are important for the diagnosis and monitoring of liver diseases. Several studies demonstrated that patients with chronic kidney disease (CKD) have lower levels of serum aminotransferases than the normal population. The present study was designed to compare these enzymes in different types of dialysis in ESRD patients and the general population in Iran.

 In this cross-sectional study, ESRD patients who were candidates for organ transplants in Montaserieh Hospital in Mashhad (Iran) from 2007 to 2014 were enrolled. The data of 1116 patients were collected by reviewing their medical records. Patients were divided into two groups of hemodialysis (n = 1034) and peritoneal dialysis (n = 82); their liver enzymes were compared with 510 healthy individuals from the MASHAD study.

 There was a significant difference between hemodialysis and peritoneal dialysis patients and the control group regarding the age (P < 0.0001) and gender (P = 0.005).

 The reduction in serum aminotransferase levels in ESRD cases compared to the control group suggested that renal failure influences liver enzymes that were mildly increased in peritoneal dialysis versus hemodialysis patients in samples provided before the dialysis session.
