Maar de werkzaamheid is nooit goed Thiopurines are often the mainstay of treatment for many patients with inflammatory bowel disease. As such, a general understanding of the evidence behind 16 okt 2019 Trefwoorden: colitis ulcerosa, dosisaanpassing, M. Crohn, myelotoxiciteit, polymorfismen, thiopurine, TPMT-deficiëntie.

Polymorfismen in het TPMT-gen komen voor bij Thiopurine methyltransferase (TPMT) katalyseert de methylering van 6- mercaptopurine. Een TPMT deficiëntie kan gepaard gaan met ernstige thiopurine - De maag-darm-leverarts (MDL-arts) heeft samen met u besloten om u te behandelen met een thiopurine (azatiopurine, pur-nethol of.

Thiopurine methyltransferase (TPMT) is an enzyme that breaks down (metabolizes) a class of drugs called thiopurines. These drugs are used to suppress the immune system and are prescribed to treat various immune-related conditions or blood disorders (e.g., leukemia). Thiopurine methyltransferase or thiopurine S-methyltransferase (TPMT) is an enzyme that in humans is encoded by the TPMT gene.A pseudogene for this locus is located on chromosome 18q. Patients with thiopurine S-methyl transferase (TPMT) or nucleotide diphosphatase (NUDT15) deficiency may be at an increased risk of severe and life-threatening myelotoxicity if receiving conventional doses of Azathioprine (see CLINCIAL PHARMACOLOGY).

Thiopurine S-Methyltransferase (TPMT) Genotype - Thiopurine S-methyltransferase (TPMT; S-adenosyl-L-methionine:thiopurine S-methyltransferase) catalyzes thiopurine S-methylation, an important metabolic pathway for antineoplastic and immunosuppressive drugs.

AU - Haglund, Sofie Catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine (also called mercaptopurine, 6-MP or its brand name Purinethol) using S-adenosyl-L-methionine as the methyl donor (PubMed:18484748). TPMT activity modulates the cytotoxic effects of thiopurine prodrugs.

In essence, although the discovery and clinical implementation of NUDT15 variant alleles in individualizing thiopurine dosing are relatively recent and the exact impact of NUDT15 genotype‐guided dose adjustments on thiopurine toxicity and efficacy are less studied compared to the well investigated TPMT‐based dose adjustments, it is clear that the addition of NUDT15 genotyping would provide

6-Mercaptopurine (6-MP) is indicated for remission induction and maintenance therapy of acute lymphoblastic leukemia (ALL). Thiopurine therapy is associated with postoperative intra-abdominal septic complications. The risk for intra-abdominal septic complications was related to the number of identified risk factors. This increased risk should be taken into consideration when planning surgery for Crohn's disease.
