Model‐Based Strategy for 6‐Mercaptopurine Treatment in Acute Lymphoblastic Leukemia Maintenance Phase: Prediction of 6‐TGN and 6‐MMP Concentrations to Optimize Treatment

Pediatric Blood &Cancer, Volume 73, Issue 4, April 2026.
ABSTRACT Introduction Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. The pro‐drug 6‐mercaptopurine (6‐MP), essential during maintenance, is converted into active 6‐thioguanine (6‐TGN) and toxic 6‐methylmercaptopurine (6‐MMP) metabolites, resulting in marked variability in efficacy and toxicity.

Case report: NUDT15 polymorphism and severe azathioprine-induced myelosuppression in a young Chinese female with systematic lupus erythematosus: a case analysis and literature review

Frontiers in Pharmacology, 2023
Azathioprine is clinically used as an immunosuppressant for treating autoimmune diseases. However it has narrow therapeutic indices due to frequent myelosuppression.

Thiopurines in inflammatory bowel disease. How to optimize thiopurines in the biologic era? [PDF]

, 2021
Thiopurines have been a cornerstone in the treatment of inflammatory bowel disease (IBD). Although they have been used for more than 50 years, there are still some unsolved issues about their efficacy and, also, some safety concerns, mainly the risk of ...

Repeated Intake of Grapefruit Juice Inhibits CYP2B6, CYP2C9, CYP2C19, and CYP3A4 while Lingonberry Powder Does Not Induce Major CYP Enzymes in Humans

Clinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 953-963, April 2026.
Grapefruit juice is a well‐established inhibitor of cytochrome P450 (CYP) 3A4, but its effects on other CYP enzymes or organic anion transporting polypeptides (OATPs) are not fully characterized in humans. Recently, lingonberry powder was shown to induce murine CYP enzymes. We investigated the effects of lingonberry powder and grapefruit juice on seven

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 ...

Usefulness and difficulties with the thiopurine pharmacogenomic NUDT15 genotyping test: Analysis of real-world data in Japan

Journal of Pharmacological Sciences, 2023
The usefulness of NUDT15 genotyping as a pharmacogenomic test for thiopurine has been established. The first such test developed to date, NUDT15 genotyping was approved for reimbursement in Japan in February 2019 for all indicated patients.

Severe myelosuppression and alopecia after thiopurine initiation in a patient with NUDT15 deficiency. [PDF]

Br J Clin Pharmacol
Thiopurines are a class of immunosuppressant and antineoplastic agents. They are widely used in the treatment of inflammatory bowel disease, haematological malignancies and autoimmune diseases, but can cause significant toxicity.

Adalimumab‐responsive Monogenic Inflammatory Bowel Disease With Pseudopolyposis Characteristic of TGFBR2 Variant in Loeys‐Dietz Syndrome

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Loeys‐Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder caused by pathogenic variants in TGFBR1 or TGFBR2. It is characterized by vascular fragility, skeletal abnormalities, and predisposition to allergic and inflammatory conditions, including monogenic inflammatory bowel disease (IBD).

Genetic profiling of NUDT15 in the Slovenian population

Pharmacogenomics
Determining variant TPMT alleles to predict patient response to thiopurine therapy represents one of the first successful implementations of pharmacogenomics in clinical practice. However, despite the TPMT-adjusted thiopurine dosing, some TPMT wild-type patients still exhibit toxicity at standard doses. Over the past decade, the pharmacogene NUDT15 has
