Test Requisition Form Red blood cell (RBC) count is first performed and then the thiopurine metabolites' values are determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Values are utilized to calculate and report a final result (unit of measure: pmol/8 x 10[8] RBC) for 6-thioguanine nucleotides and 6-methylmercaptopurine derivative analyte. 2011 (English) In: Therapeutic Drug Monitoring, ISSN 0163-4356, E-ISSN 1536-3694, Vol. 33, no 2, p. 200-208 Article in journal (Refereed) Published Abstract [en] BACKGROUND:: There is a large interindividual variability in thiopurine metabolism. High concentrations of methylthioinosine-5'-monophosphate (meTIMP) and low concentrations of 6-thioguanine nucleotides (6-TGNs) have been associated The pharmacokinetic effect of discontinuation of mesalazine on mercaptopurine metabolite levels in inflammatory bowel disease patients. Aliment Pharmacol Ther 2005; 22:605.

2013-07-01 Purpose: Recent studies in patients with inflammatory bowel diseases (IBD) on thiopurine therapy suggest that too low 6-thioguanine nucleotide concentrations (6-TGN) and too high methylmercaptopurine nucleotide concentrations (MMPN) can be reversed by a combination therapy of allopurinol and low-dose thiopurines. 2012-07-01 Azathioprine (AZA) is characterized by a high interindividual variability in bioavailability and metabolism. AZA is converted into 6-thioguanine nucleotides (6-TGN) to which the immune modifier activity is attributed.

Moderate to high concentrations of TGN metabolites; low concentrations of MeTIMP. Increased risk of thiopurine-related leukopenia, neutropenia, and myelosuppression. Normal metabolizer: An individual carrying TWO normal function alleles: Lower concentrations of TGN metabolites, higher MeTIMP, this is the “normal” pattern.

Normal metabolizer: An individual carrying TWO normal function alleles: Lower concentrations of TGN metabolites, higher MeTIMP, this is the “normal” pattern. Primary metabolic route for inactivation of thiopurine drugs is catalyzed by TPMT Low TPMT activity: more 6-MP may be converted into active (cytotoxic) 6-TGN, which accumulates Excess 6-TG in bone marrow (BM) inhibits purine synthesis thiopurine metabolite measurement, several scenarios may occur. If both metabolites are undetectable it is likely that the patient is not taking the medication and adherence to therapy should be discussed.

Patients with low activity (10% prevalence) or especially absent activity (prevalence 0.3%) are at a heightened risk of drug-induced bone marrow toxicity due to accumulation of the unmetabolised drug.

Thiopurine management is important because it can detect individuals with low thiopurinemethyltransferase (TPMT) activity who are at risk for excessive myelosuppression or severe hematopoietic toxicity when taking thiopurine drugs. Thiopurine drugs are widely used in the treatment of inflammatory and autoimmune diseases, leukaemia and prevention of rejection post organ transplant. Thiopurines are catabolised to inactive metabolites by thiopurine methyl transferase (TPMT), which in effect reduces concentrations of the active metabolite, 6-thioguanine nucleotides (6TGN). 2021-02-19 standard solution of thiopurine metabolites is shown.

Thiopurine S-methyltransferase (TPMT) deficiency is a condition characterized by significantly reduced activity of an enzyme that helps the body process drugs called thiopurines. These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system. Thiopurine drugs are used to treat some

Meijer et al. evaluated the effects of thiopurine metabolites on clinical signs and if patient characteristics affected metabolite generation. 940 “laboratory findings” from 424 patients were examined. 6-TGN (a metabolite of azathioprine [AZA] and mercaptopurine) was found to negatively correlate with RBC count, WBC count, and neutrophil count.

2006 Oct;62 (4):453-6. Exposure to thiopurine drugs through breast milk is low based on metabolite concentrations in mother-infant pairs. Thiopurine dose was optimized in 20 (26.31%) patients. Dose-based metabolite levels were comparable to Asian and Caucasian patients. The toxicity (8%) observed in our patients was less than that reported (12-39%).
