Abstract/OtherAbstract:
BACKGROUND: A direct relationship between serum bile acids (SBA) and hepatic and hepatobiliary dysfunction has been demonstrated. However, there is little evidence that SBA are related to renal insufficiency. In a previous study, we showed that hemodialysis patients with advanced chronic renal failure (ACRF) have an increase of SBA in predialysis and a decrease in postdialysis. Consequently, it was assumed that the restoration of renal function in transplanted patients might decrease SBA levels. AIM OF THIS STUDY: Transplanted patients receiving cyclosporine A (CyA) were studied by monitoring CyA and SBA levels to determine if a probable relationship exists between renal function, CyA treatment and SBA levels. SUBJECTS. MATERIALS AND METHODS: SBA levels were determined in 15 recently transplanted patients receiving CyA for 18 months and longer. In addition, 22 renal patients transplanted not less than 6 years ago were also included in the study and were characterized as the stable group. Five patients from this group received mycophenolate or azathioprine instead of CyA as immunosuppressant. In addition to SBA and CyA, creatinine, cholesterol, y-GT, viral markers and triglycerides were also determined in all patients. RESULTS: A significant and constant increase in SBA levels was observed in the recently transplanted group. However, after 18 months, SBA levels gradually decreased to those of patients considered stable under CyA treatment. In both recently transplanted and stable patients who received CyA, SBA values remained higher than normal, but stable patients under mycophenolate or azathioprine treatment showed no such increase. CONCLUSIONS: In recently transplanted patients, in patients studied for 18 months post transplant and in stable patients receiving CyA, the increase of SBA levels might be related to CyA treatment. This effect might be attributed to its cholestatic effect and also to a modification in uptake, metabolism, synthesis and excretion of SBA in the hepatocyte. These conclusions are supported by the results obtained in stable transplanted patients without CyA treatment showing normal SBA levels.
