INTRODUCTION: A systematic bias against women, resulting from the use of creatinine as a measure of renal function, has been identified in Model for End-stage Liver Disease (MELD)-based liver allocation. Correction of this bias by calculation of female creatinine levels using the Modification of Diet in Renal Disease (MDRD) formula has been suggested. MATERIAL AND METHODS: A cohort of 639 cirrhotic candidates for first-time liver transplantation was studied. Creatinine levels were corrected for gender using the MDRD formula. The accuracy of MELD, with or without creatinine correction, to predict 3-and 6-month mortality after inclusion in a transplant waiting list was estimated. RESULTS: Women exhibited significantly lower creatinine levels, glomerular filtration rate, and MELD scores than men. After creatinine correction, female MELD scores had a mean increase of 1.1 points. Creatinine correction yielded an increase of 3 points in the MELD score in 15.2% of patients, 2 points in 22.4%, and 1 point in 17.6% of patients. The likelihood of death at 3 and 6 months after enrollment in the transplant waiting list was similar in males and females and the likelihood of receiving a transplant, as assessed by Kaplan-Meier survival curves, was also similar in males and females. CONCLUSION: The survival or the likelihood of receiving a transplant while on the waiting list were similar in men and women in both pre- and post-MELD eras and creatinine correction did not increase the accuracy of the MELD score in estimating 3- and 6-month mortality in female candidates for liver transplantation.
