2.1.1.67 | analysis |
determination of thiopurine S-methyltransferase activity in erythrocytes using 6-thioguanine as substrate and a non-extraction liquid chromatographic technique. This method minimzes sample-handling, reduces inherent imprecision, the possibility of laboratory error and with the potential for further automation, makes it ideal for use in a regional refferal laboratory |

2.1.1.67 | analysis |
monitoring of 6-thiopurine S-methyltransferase activity is especially important when patients are treated with 6-thiopurine drugs (drugs in treatment of acute lymphoblastic leukemia), since severe bone marrow toxicity may be induced if patients have deficient 6-thiopurine S-methyltransferase activity. The HPLC-based method enables the rapid screening of 6-6-thiopurine S-methyltransferase activities in patients treated with 6-thiopurines |

2.1.1.67 | medicine |
azathioprine sodium is a purine antagonist commonly used as an adjuvant immunosuppressive agent in treating Pemphigus Vulgaris, mercaptopurine is the active compound, TPMT is the principal inactivation enzyme for this cytotoxic metabolite in hematopoietic tissues |

2.1.1.67 | medicine |
detecting TPMT genetic variants before the administration of azathioprine has the potential to prevent serious and costly adverse drug reactions, such as neutropenia |
687195 |
2.1.1.67 | medicine |
determination of TPMT and monitoring of thiopurine metabolites allows azathioprine treatment to be optimised |

2.1.1.67 | medicine |
enzyme activity might represent one factor responsible for variations in the therapeutic or toxic effects of thiopurine and thiopyrimidine drugs used clinically to treat recipients of transplanted kidneys and patients with renal disease such as glomerulonephritis |
