Azathioprine and 6-mercaptopurine for maintenance of surgically-induced remission in Crohn’s disease. Cochrane Database Syst Rev. 2019 Aug 06;8:CD010233 Authors: Gjuladin-Hellon T, Iheozor-Ejiofor Z, Gordon M, Akobeng AK Abstract BACKGROUND: Crohn’s disease (CD) is a chronic relapsing inflammatory condition and maintenance of remission is a major issue as many patients fail to achieve remission with medical management and require surgical interventions. Purine analogues such as azathioprine (AZA) and 6-mercaptopurine (6-MP) have been used to maintain surgically-induced remission in CD, but the effectiveness, tolerability and safety of these agents remains controversial. OBJECTIVES:…

Thiopurine Therapy in Patients With Inflammatory Bowel Disease: A Focus on Metabolism and Pharmacogenetics. Dig Dis Sci. 2019 Jul 09;: Authors: Chang JY, Cheon JH Abstract Thiopurines have been widely used for the maintenance of remission or steroid sparing in patients with inflammatory bowel disease. However, potential drug-related adverse events frequently interfere with their use. Indeed, drug withdrawals associated with adverse reactions have been reported in approximately 25% of patients. To balance the efficacy, safety, and tolerability of thiopurines, regular monitoring of biomarkers (complete blood cell count, liver function test,…

J Crohns Colitis. 2019 Mar 19;: Authors: Borren NZ, Luther J, Colizzo FP, Garber JG, Khalili H, Ananthakrishnan AN Abstract BACKGROUND AND AIMS: Methotrexate [MTX] is a well-known immunomodulator in the treatment of inflammatory bowel disease [IBD] and is often combined with biologic agents. The ideal MTX dose for combination therapy has not been determined. This study aimed to investigate the effect of varying doses of MTX on efficacy and safety outcomes when…
