Thiopurine methyltransferase screening before azathioprine therapy [PDF]

open access: bronzeBritish Journal of Ophthalmology, 2006
Azathioprine is used to treat various inflammatory eye conditions such as uveitis and dysthyroid orbitopathy. Despite good overall clinical response rates, particularly when used as steroid sparing agent, adverse effects such as severe myelosuppression can lead to early withdrawal in approximately a quarter of patients.1,2 Thiopurine methyltransferase

NUDT15 Pharmacogenetics in Acute Lymphoblastic Leukemia: Synthesizing Progress for Personalized Thiopurine Therapy [PDF]

open access: yesMedical Sciences
The management of acute lymphoblastic leukemia (ALL), the most common pediatric malignancy, critically relies on thiopurine therapy, such as 6-mercaptopurine (6-MP), during the maintenance phase. However, significant inter-individual response variety and

Thiopurine methyltransferase in acute lymphoblastic leukemia [PDF]

open access: bronzeBlood, 2006
We recently reported that specific genetic polymorphisms, particularly polymorphisms in thymidylate synthase (TYMS) and glutathione S -transferase M1 (GSTM1) predicted the risk of relapse among children with acute lymphoblastic leukemia (ALL).[1][1] An accompanying commentary noted surprise that ...

Thiopurine methyltransferase polymorphisms in children with acute lymphoblastic leukemia

open access: yesIndian Journal of Medical and Paediatric Oncology, 2014
Introduction: Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. 6-mercaptopurine (6-MP) and methotrexate are backbone drugs for maintenance phase of treatment. Purine Analogs 6-MP/6-thioguanine/azathiopurine are metabolized to

Thiopurine S -methyltransferase polymorphisms: efficient screening method for patients considering taking thiopurine drugs [PDF]

open access: yesEuropean Journal of Clinical Pharmacology, 2018
Objective: More than 11% of the Caucasian population are heterozygous or homozygous carriers of thiopurine S-methyltransferase (TPMT) mutants and are at risk for toxic side effects when treated with thiopurine drugs.

A Rapid and Reliable Absorbance Assay to Identify Drug–Drug Interactions with Thiopurine Drugs [PDF]

open access: yesMetabolites
Background: Thiopurine methyltransferase (TPMT) plays a crucial role in the detoxification of thiopurine drugs, including the antimetabolites azathioprine and 6-mercaptopurine (6-MP) used to treat autoimmune diseases and various cancers.
