Clinical Utility of Thiopurine Metabolites. Two Australian studies have highlighted the ability of thiopurine metabolite testing to improve outcomes with thiopurine therapy. 27, 28 Both clustered patient results into five groups (see Table 1): underdosed/rapid metabolisers, non‐adherent, refractory, ‘thiopurine shunters’ and overdosed

The metabolism of thiopurines is dependent on a major enzymatic pathway that involves thiopurine S-methyltransferase (TPMT). TPMT activity reference intervals

Journal of Hepatology, 52, 106-111. 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. 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).

23 Jul 2020 These target levels help monitor a patient's metabolism of thiopurine drug therapy. Lab Testing Sections: Chemistry - Sendouts. Referred to: Mayo

Thiopurine metabolites were monitored since September 2010. Among them, 83 patients who had prescribed AZA for at least 3 months prior to September 2010 were enrolled and followed until October 2011 to evaluate optimal AZA dose, adverse effects and disease activity before and after thiopurine metabolite monitoring.

Following uptake by transporters, MP undergoes metabolism by three compet-ing pathways (see figure 1) to form the active metabolite, thioguanine nucleo-tides (TGNs) which function A healthcare practitioner may order a blood test for thiopurine metabolites to monitor drug therapy.

Thiopurine Metabolites (6-TGN, 6-MMPN) Clinical Background: The immunosuppressive effect of thiopurine drugs (like azathioprine) is mediated primarily by the cytotoxic metabolite 6TGN, and incorporation of these false bases into DNA. Once thiopurine therapy has been undertaken and an equilibrated drug level is achieved (usually three to six months), literature suggests that the measurement of thiopurine metabolites is warranted in the following situations: 1.
