Thiopurine methyltransferase genotype and thiopurine S-methyltransferase activity in Greek children with inflammatory bowel disease
BACKGROUND Azathioprine (AZA) and 6-mercaptopurine (6MP) are used in the treatment of pediatric inflammatory bowel disease (IBD). Genetic variations in thiopurine S-methyltranfarase (TPMT) gene have been correlated with enzyme activity and with the occurrence of adverse events to AZA and 6MP. The aim of the present study was to examine the sensitivity and specificity of TPMT genotyping for TPMT...
متن کاملThiopurine methyltransferase phenotypes and genotypes in Brazilians.
The polymorphism of thiopurine methyltransferase (TPMT) was studied in 306 healthy Brazilians who were classed, on the basis of self-declared colour and ancestry, as Euro-derived (n = 81), Afro-derived (n = 18) or having interethnic admixture (n = 204). TPMT activity (range 0.17-25.93 U) displayed a trimodal distribution of high (> 11.3 U; 9% of individuals), intermediate (5-11.3 U; 9.8%) and l...
متن کاملThiopurine S-methyltransferase and Pemphigus Vulgaris: A Phenotype-Genotype Study
Background & Objective: Thiopurine drugs are considered as a treatment modality in various autoimmune disorders including pemphigus vulgaris (PV). These drugs are metabolized by an enzyme “Thiopurine S-methyl transferase” (TPMT). Various variants of this enzyme may have decreased activity lead...
متن کاملPharmacogenetics of thiopurine S-methyltransferase and thiopurine therapy.
Most medications exhibit wide interpatient variability in their efficacy and toxicity. For many medications, these interindividual differences result in part from polymorphisms in genes encoding drug-metabolizing enzymes, drug transporters, and/or drug targets (eg, receptors, enzymes). Pharmacogenomics is a burgeoning field aimed at elucidating the genetic basis of differences in drug efficacy ...
