Thiopurine S-methyltransferase phenotype-genotype correlation in hemodialyzed patients.
Thiopurine S-methyltransferase (TPMT) is a cytosolic enzyme, catalyzing S-methylation of thiopurine drugs. TPMT exhibits autosomal codominant polymorphism. Patients carrying a variant genotype have low TPMT activity, and produce elevated levels of 6-thioguanine nucleotides (6-TGN) in their red blood cells (RBC). 6-TGN accumulation may result in azathioprine (AZA)-induced bone marrow myelosuppre...
متن کامل[Phenotype and genotype of thiopurine methyltransferase in Chilean individuals].
BACKGROUND Thiopurines (azathioprine and 6-mercaptopurine) are highly effective medications but with potential adverse effects. Thiopurine methyltransferase (TMPT) is the key enzyme in their pharmacokinetics and is genetically regulated. A low activity of TPMT is associated with myelotoxicity. The genotype and enzyme activity can vary by ethnicity. AIM To study the activity and genotype of TP...
متن کاملThiopurine 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 کاملAssessment of Thiopurine–based drugs according to Thiopurine S-methyltransferase genotype in patients with Acute Lymphoblastic Leukemia
For the past half century, thiopurines have earned themselves a reputation as effective anti-cancer and immunosuppressive drugs. Thiopurine S-methyltransferase (TPMT) is involved in the metabolism of all thiopurines and is one of the main enzymes that inactivates mercaptopurine. 6-MP is now used as a combination therapies for maintenance therapy of children with acute lymphocytic leukemia (A...
