Biomarkers Predictive of Response to Thiopurine Therapy in Inflammatory Bowel Disease

Frontiers in Medicine, 2020
The complex nature of inflammatory bowel disease (IBD) often results in treatment failure for many patients. With some patients cycling through multiple therapies before achieving a sustained period of remission, the ability to predict a patient's ...

The Thiopurine Tale: An Unexpected Journey [PDF]

Journal of Crohn's and Colitis, 2022
Abstract Exactly 70 years ago [1951] mercaptopurine was discovered by Gertrude Elion as a novel treatment option for acute leukaemia. A total of three thiopurines (also thioguanine [1950] and azathioprine [1957]) were developed over time.

6-thioguanine treatment in inflammatory bowel disease: A critical appraisal by a European 6-TG working party [PDF]

, 2006
Recently, the suggestion to use 6-thioguanine (6-TG) as an alternative thiopurine in patients with inflammatory bowel disease (IBD) has been discarded due to reports about possible (hepato) toxicity. During meetings arranged in Vienna and Prague in 2004,

Revisiting the Role of Thiopurines in Inflammatory Bowel Disease Through Pharmacogenomics and Use of Novel Methods for Therapeutic Drug Monitoring

Frontiers in Pharmacology, 2018
Azathioprine and 6-mercaptopurine, often referred to as thiopurine compounds, are commonly used in the management of inflammatory bowel disease. However, patients receiving these drugs are prone to developing adverse drug reactions or therapeutic ...

Effects of PRPS1 I72 mutations on drug resistance in acute lymphoblastic leukemia and its mechanisms

Shanghai Jiaotong Daxue xuebao. Yixue ban, 2023
Objective·To study whether mutations at the I72 site of phosphoribosyl pyrophosphate synthetase 1 (PRPS1) can induce resistance in acute lymphoblastic leukemia (ALL) cells to thiopurine chemotherapy drugs 6-mercaptopurine (6-MP) and 6-thioguanine (6-TG),

Apoptosome activation, an important molecular instigator in 6-mercaptopurine induced Leydig cell death. [PDF]

, 2015
Leydig cells are crucial to the production of testosterone in males. It is unknown if the cancer chemotherapeutic drug, 6-mercaptopurine (6 MP), produces Leydig cell failure among adult survivors of childhood acute lymphoblastic leukemia. Moreover, it is

Clinical application of high throughput molecular screening techniques for pharmacogenomics. [PDF]

, 2011
Genetic analysis is one of the fastest-growing areas of clinical diagnostics. Fortunately, as our knowledge of clinically relevant genetic variants rapidly expands, so does our ability to detect these variants in patient samples.

Measurements of 6-thioguanine nucleotide levels with TPMT and NUDT15 genotyping in patients with Crohn's disease.

PLoS ONE, 2017
The association between the 6-thioguanine nucleotide (6-TGN) level and clinical remission in Crohn's disease (CD) remains controversial. Thiopurine-induced leukopenia is a life-threatening complication of CD in Asians that was recently shown to strongly ...

Pharmacogenetics of thiopurines

Cancer Drug Resistance, 2019
Polychemotherapeutic protocols for the treatment of pediatric acute lymphoblastic leukemia (ALL) always include thiopurines. Specific approaches vary in terms of drugs, dosages and combinations. Such therapeutic schemes, including risk-adapted intensity, have been extremely successful for children with ALL who have reached an outstanding 5-year ...

gene variants and thiopurine-induced leukopenia in patients with inflammatory bowel disease [PDF]

Intestinal Research, 2020
Thiopurine has been used to maintain remission and to reduce antidrug antibody formation in monoclonal antibody therapy in patients with inflammatory bowel disease (IBD). The use of thiopurine is limited by side effects such as leukopenia.
