The decline of 6‐thioguanine nucleotides is not linked to impaired efficacy or safety of thiopurines in pregnant women with inflammatory bowel disease

British Journal of Clinical Pharmacology, EarlyView.
Background Thiopurines are used to maintain remission in inflammatory bowel disease (IBD). These drugs are metabolized into 6‐thioguanine nucleotides (6‐TGN), associated with efficacy, and 6‐methylmercaptopurine ribonucleotides (6‐MMPR), associated with adverse drug reactions. Pregnancy has been linked to a shift in thiopurine metabolism, characterized

The Utility of Thiopurine Methyltransferase Enzyme Testing in Inflammatory Bowel Disease

Canadian Journal of Gastroenterology, 2013
OBJECTIVE: To assess the levels of red blood cell thiopurine methyltransferase (TPMT) in subjects with inflammatory bowel disease (IBD) and to determine how these levels impacted thiopurine dosing and leukopenia over the first six months of therapy.

Clinical Pharmacogenetics Implementation Consortium Guidelines for Thiopurine Methyltransferase Genotype and Thiopurine Dosing [PDF]

Clinical Pharmacology & Therapeutics, 2011
Thiopurine methyltransferase (TPMT) activity exhibits monogenic co-dominant inheritance, with ethnic differences in the frequency of occurrence of variant alleles. With conventional thiopurine doses, homozygous TPMT-deficient patients (~1 in 178 to 1 in 3,736 individuals with two nonfunctional TPMT alleles) experience severe myelosuppression, 30-60% of

Concomitant 5‐Aminosalicylic Acid Does Not Affect the Efficacy of Janus Kinase Inhibitors in Ulcerative Colitis

Clinical Pharmacology &Therapeutics, EarlyView.
We evaluated whether concomitant 5‐aminosalicylic acid (5‐ASA) influences clinical remission in patients with ulcerative colitis (UC) receiving Janus kinase inhibitors (JAKi). In this retrospective, multicenter cohort study, UC patients receiving tofacitinib (n = 181), upadacitinib (n = 313), or filgotinib (n = 139) were included.

Drug metabolizing enzyme activities versus genetic variances for drug of clinical pharmacogenomic relevance [PDF]

, 2011
Enzymes are critically important in the transportation, metabolism, and clearance of most therapeutic drugs used in clinical practice today. Many of these enzymes have significant genetic polymorphisms that affect the enzyme's rate kinetics.
