Personalization of thiopurine therapyUrbančič, Dunja (Avtor) Pasha, Flaka (Avtor) Šmid, Alenka (Avtor) Mlinarič-Raščan, Irena (Avtor) thiopurinesTPMTNUDT15personalized medicinetherapeutic drug monitoringDespite great therapeutic advances in the field of biologics, small synthetic molecules such as thiopurines, including azathioprine, mercaptopurine, and thioguanine, remain an important therapeutic pillar in the treatment of inflammatory bowel disease, other autoimmune disorders, and cancer. This review presents the latest guidelines for thiopurine administration, highlighting the importance of individualized therapy guided by pharmacogenomics. It emphasizes dose adjustment based on nudix hydrolase 15 (NUDT15) and thiopurine S-methyltransferase (TPMT) genotype, alongside thiopurine S-methyltransferase activity and thiopurine metabolic profile. In addition, the article takes a critical look at emerging research in the field of thiopurine pharmacogenomics featuring novel genetic markers and technological developments in genetic testing. Finally, the potential of integrated approaches that combine genetic, metabolic, and clinical factors to further individualize thiopurine therapy is highlighted.20242024-10-08 12:17:00Članek v reviji163535sl
