AZA and MP have no intrinsic Thiopurine Metabolites - 6-Mercaptopurine (Purinethol) and its imidazolyl derivative, Azathioprine (Imuran), are immunosuppressive drugs. 6- Mercaptopurine Thiopurine metabolites, TGN and in many cases meTIN, are currently measured in red blood cells (RBCs) [6, 7] or whole blood . However, the choice of matrix Thiopurine metabolite testing is routinely used for: · If remission is not achieved on the current dose, finding safe, higher dose if possible; · When side effects occur, aid in optimization of ongoing dosing of thiopurines in order to reach and maintain a insurance correspondence for PROMETHEUS® Thiopurine Metabolites.

Aliment Pharmacol Ther 2005; 22:605. de Boer NK, Wong DR, Jharap B, et al. Dose-dependent influence of 5-aminosalicylates on thiopurine metabolism. 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.

This assay measures the red-cell concentration of 6-MMP (formed from 6-MP by thiopurine methyltransferase) and also measures the concentration of the resulting 6-TG after removal of the mono-, di-, or tri-phosphates from the various 6-thioguanine nucleotides. Results can be used as an aid in optimization of ongoing dosing of thiopurines in order to reach and maintain a desired clinical response.

6-Mercaptopurine (6-MP) is indicated for remission induction and maintenance therapy of acute lymphoblastic leukemia (ALL). Adding allopurinol to thiopurine therapy is another proposed alternative for those preferential 6MMP metabolisers since it has been shown to improve therapeutic 6TGN levels and decrease serum concentrations of toxic 6MMP metabolite.73–75 The precise mechanism by which allopurinol is useful in shifting metabolites towards 6TGN production remains unclear, although some alternatives have been 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 Background: Thiopurine use in inflammatory bowel disease (IBD) is limited by drug toxicity and lack of therapeutic efficacy. We assessed the utility of thiopurine metabolite testing and the relationship between disease activity, dose, and metabolite levels in a real world setting.

A majority of patients respond well to thiopurine drugs, but up to a third have to modify or discontinue their treatment due to adverse events or lack of treatment effect .

Metabolite testing shuld not replace laboratory monitoring for toxicity. 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. Thiopurine Metabolites: 3400000: 3400001: 6-Thioguanine: 32660-3: No: 3400002: 6-Methylmercaptopurine: 32654-6: No: Need Help? We can help you find the right test or Thiopurine Metabolites, B Overview Useful For Aids physicians in dose adjustments, minimizing dose-dependent toxicity, and monitoring compliance of thiopurine drug therapy Testing Algorithm Red blood cell (RBC) count is first performed and then the thiopurine metabolites' values are determined by liquid chromatography-tandem mass spectrometry THIOPURINE METABOLISM The prodrug AZA is converted non-enzymatically by biogenic thiols, including glutathione, to MP with the release of methyl-4-nitro-5-imidazole. 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.
