Abstract:
:The purpose of the study was to determine if UDP-glucuronosyltransferase (UGT) 2B7 allelic variants encoding for UGT2B7, primary enzyme responsible for morphine glucuronidation contribute to the variability in the hepatic clearance of morphine in sickle cell disease (SCD). Twenty-four hour PK study of morphine and UGT2B7 variants genotyping was performed in 20 SCD patients in a steady state of health. Presence of the -840G allele (GG and GA) was associated with lower morphine metabolites/morphine AUC ratio compared with AA genotype (1.8 +/- 0.5 vs. 3.0 +/- 1.8 for M6G/M and 10.1 +/- 2.7 vs. 15.7 +/- 9.4 for M3G/M) (P = 0.03). Presence of UGT2B7 -840G allele is associated with significantly reduced glucuronidation of morphine and thus contributes to the variability in hepatic clearance of morphine in SCD.
