Inflammatory bowel disease surgery in the biologic era.

ABSTRACT: Anti-tumour necrosis factor (TNF)-? therapy has revolutionized inflammatory bowel disease (IBD) treatment. Infliximab and adalimumab either as monotherapy or in combination with an immunomodulator are able to induce clinical and biological remission in patients with moderate and severe Crohn's disease (CD) and ulcerative colitis (UC). These new therapies have led to a shift in the goals of IBD management from just controlling clinical symptoms to preventing disease progression. However, despite these advances in medical therapy, surgery is still required in 30%-40% of patients with CD and 20%-30% of patients with UC at some point during their lifetime. While biologics certainly play a major role in the medical treatment of IBD, there is concern about the effects of these anti-TNF-? agents on postoperative complications and morbidity. The purpose of this article is to review the role of surgery in the treatment of IBD in the age of biologics and the impact of these medications on per-operative outcomes. In this manuscript we review the relationship between biologic agents and surgery in the treatment of IBD. We also discuss in detail the periopetative risks and complications.

Anti-tumour necrosis factor (TNF)-α therapy has revolutionized inflammatory bowel disease (IBD) treatment.

Project description:Thiopurines have been a cornerstone in the treatment of inflammatory bowel disease (IBD). Although they have been used for more than 50 years, there are still some unsolved issues about their efficacy and, also, some safety concerns, mainly the risk of myelosuppression and life-threatening lymphoproliferative disorders. Furthermore, the development of biological therapy raises the question whether there is still a role for thiopurines in the IBD treatment algorithm. On the other hand, limited cost and wide availability make thiopurines a reasonable option in settings of limited resources and increasing prevalence of IBD. In fact, there is a growing interest in optimizing thiopurine therapy, since pharmacogenomic findings suggest that a personalized approach based on the genotyping of some molecules involved in its metabolism could be useful to prevent side effects. Polymorphisms of thiopurine methyltransferase enzyme (TPMT) that result in low enzymatic activity have been associated with an increased risk of myelotoxicity, especially in Caucasians; however, in Asians it is assumed that the variants of nudix hydrolase 15 (NUDT15) are more relevant in the development of toxicity. Age is also important, since in elderly patients the risk of complications seems to be increased. Moreover, the primo-infection of Epstein Barr virus and cytomegalovirus under thiopurine treatment has been associated with severe lymphoproliferative disorders. In addition to assessing individual characteristics that may influence thiopurines treatment outcomes, this review also discusses other strategies to optimize the therapy. Low-dose thiopurines combined with allopurinol can be used in hypermethylators and in thiopurine-related hepatotoxicity. The measurement of metabolites could be useful to assess compliance, identify patients at risk of adverse events and also facilitating the management of refractory patients. Thioguanine is also a rescue therapy in patients with toxicity related to conventional thiopurine therapy. Finally, the current indications for thiopurines in monotherapy or in combination with biologics, as well as the optimal duration of treatment, are also reviewed.
