Importance of Thiopurine S-Methyltransferase gene polymorphisms for prediction of azathioprine toxicity

Popis výsledku v původním jazyce

OBJECTIVES: Our study aims to find the relationship between metabolic enzyme thiopurine S-methyltransferase (TPMT) gene polymorphisms and clinical output of the therapy with azathioprine. We focused on patients who experienced leucopenia caused by high blood levels of active azathioprine metabolites. DESIGN: Our group consists of 87 patients who have been treated by azathioprine. 21 individuals experienced leucopenia during treatment with standard dose of azathioprine. We have used PCR-REA and real-timePCR methods for genotype detection G238C, G460G and A719G substitutions in TPMT gene. RESULTS: We have found statistical association between the presence of non-standard TPMT alleles and adverse event associated with azathioprine treatment leucopenia (p=0.0033). CONCLUSION: Our results confirm that TPMT genotyping prior to the treatment with azathioprine could predict patients with genetic predisposition for serious leucopenia and seems to be a useful genetic marker for individualisatio
