Measurement of thiopurine methyltransferase activity and azathioprine metabolites in patients with inflammatory bowel disease.
BACKGROUND Measurement of 6-thioguanine nucleotide concentrations may be useful for optimising treatment with azathioprine and 6-mercaptopurine. METHODS We conducted a study of 170 patients with inflammatory bowel disease treated with azathioprine or 6-mercaptopurine to determine the relationship between 6-thioguanine nucleotide concentrations and both disease activity, as measured by the inf...
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 کاملDosing azathioprine in thiopurine S-methyltransferase deficient inflammatory bowel disease patients.
With great interest we read the article by Kaskas et al (Gut 2003;52:140–2) about safe treatment of thiopurine S-methyltransferase (TPMT) deficient Crohn’s disease patients with azathioprine (AZA). In this paper it is illustrated that TPMT-deficient patients can be successfully treated with very low doses of AZA (,10% of standard initial dose). Unfortunately, this is not the case for all homozy...
متن کاملCost-effectiveness of thiopurine methyltransferase genotype screening in patients about to commence azathioprine therapy for treatment of inflammatory bowel disease.
BACKGROUND Azathioprine is a useful agent in the management of inflammatory bowel disease. Its use is limited by its side-effect profile. Marrow toxicity occurs in approximately 3.2% of patients and is known to be associated with diminished thiopurine methyltransferase enzyme activity resulting from genetic polymorphisms. AIM To evaluate the cost-effectiveness of screening for thiopurine meth...
متن کاملThiol methyltransferase activity in inflammatory bowel disease.
BACKGROUND Luminal anionic sulphide may contribute to epithelial damage in ulcerative colitis. Thiol methyltransferase (TMT) governs sulphide detoxification by the colonic mucosa and circulating erythrocytes. AIMS To measure levels of TMT activity in erythrocytes of surgically treated cases of colitis or in rectal biopsies of defined groups of colitis. PATIENTS Venepuncture blood was obtain...
