Pharmacogenetics of thiopurine therapy: from thiopurine S-methyltransferase to S-adenosylmethionine [PDF]

BMC Pharmacology, 2009
Background The efficiency and safety of the thiopurine therapy rely on the concentration of patient’s cytotoxic thioguanine nucleotides (TGN), which in turn depend on the deactivation of thiopurine drugs by thiopurine S-methyltransferase (TPMT). The activity of TPMT largely depends on the presence of genetic polymorphisms. Determination of mutations in

Loss of Response to Anti‐Tumor Necrosis Factor Alpha Therapy in Patients With Inflammatory Bowel Disease: A Real‐World Comparison of Combination Therapy Versus Monotherapy

JGH Open, Volume 10, Issue 3, March 2026.
ABSTRACT Objectives The success of anti‐TNFα agents has changed the landscape of treatment for inflammatory bowel diseases (IBD). One major limitation to this success is the secondary loss of response (sLOR) phenomenon. Combination therapy with immunomodulating agents has been shown to be effective in reducing the sLOR process.

Therapy de‐escalation in paediatric patients with inflammatory bowel disease in remission: Data analysis from the CEDATA registry

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 3, Page 690-698, March 2026.
Abstract Objectives There are no standardized criteria about stepping down from combination therapy (immunomodulator and tumor necrosis factor (TNF)‐alpha‐inhibitors) in children with inflammatory bowel disease (IBD) to reduce risk for side effects. Our aim was to describe how de‐escalation has been performed in a large paediatric cohort and to find ...

Adequate vitamin D is associated with favorable disease outcome in children with inflammatory bowel disease receiving anti‐tumor necrosis factor alpha therapy

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 3, Page 708-717, March 2026.
Abstract Objectives Deficiency of serum 25‐hydroxyvitamin D [25(OH)D] was associated with decreased short‐term response to anti‐tumor necrosis factor‐alpha (TNF‐α) agents in adults with inflammatory bowel disease (IBD). The aim of this study was to evaluate the association between serum 25(OH)D levels and the outcome of children with IBD undergoing ...

Unraveling the Link Between Azathioprine and Acute Pancreatitis: Integrating Network Toxicology, Machine Learning, and Mendelian Randomization

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 3, March 2026.
ABSTRACT Azathioprine (AZA), a widely used immunosuppressant, can induce acute pancreatitis (AP), yet the underlying molecular mechanisms remain unclear. This study employed an integrative multiomics strategy—combining network toxicology, machine learning, Mendelian randomization (MR), and molecular docking—to elucidate the biological basis of AZA ...
