Performance of Cimetidine-corrected MDRD Equation in Renal Transplant Patients

• Status: Completed
• Trial end date: 2008-03-01
• Target enrollment: 0
• Participant gender: All

Summary

Among the different creatinine-based GFR predicting equations, the MDRD equation gives the best prediction in renal transplantation but does not provide the level of accuracy usually seen in renal patients with native kidneys.

Blocking the tubular secretion of creatinine with an oral administration of cimetidine is likely to make creatinine a more accurate marker of GFR.

We will test the hypothesis that the accuracy of the MDRD equation will be improved in renal transplant patients by incorporating into the equation a cimetidine-corrected serum creatinine value.
