TPMT in the treatment of Crohn's disease with azathioprine.
Azathioprine induced profound myelosuppression linked to TPMT deficiency has now been documented in many patient groups, including those with Crohn's disease. At the start of azathioprine or mercaptopurine therapy, measurement of TPMT activity has a role in identifying the 1 in 300 patients who are at risk of severe myelosuppression when treated with standard thiopurine dosages. During the init...
متن کاملGenetic Predictors of Azathioprine Toxicity and Clinical Response in Patients with Inflammatory Bowel Disease.
BACKGROUND Thiopurines (Azathioprine (AZA) and 6-Mercaptopurine (6-MP) are considered a well-established therapy for patients with Inflammatory Bowel Disease (IBD) including ulcerative colitis (UC) and Crohn's Disease (CD). However, nearly 20% of patients discontinue thiopurines due to adverse events. Functional polymorphisms of several enzymes involved in the metabolism of thiopurines have bee...
متن کاملThiopurine methyltransferase (TPMT) genotyping to predict myelosuppression risk
Azathioprine (AZA), 6-mercaptopurine (6-MP), and thioguanine (TG) are thiopurine drugs. These agents are indicated for the treatment of various diseases including hematologic malignancies, inflammatory bowel disease (IBD), rheumatoid arthritis, and as immunosuppressants in solid organ transplants. Thiopurine drugs are metabolized, in part, by thiopurine methyltransferase (TPMT). TPMT displays g...
متن کاملAzathioprine induced pneumonitis in a patient with ulcerative colitis.
Immunomodulator therapy with the thiopurine analogues azathioprine (AZA) or 6-mercaptopurine (6-MP) is commonly prescribed for maintenance of remission in inflammatory bowel disease (IBD). Ten to twenty-five percent of patients have to withdraw from AZA or 6-MP due to adverse events that are partly explained by the relative activity of the drug metabolizing enzymes. Most of the potential major ...
