Background and aim Tacrolimus (tac) is used for induction therapy in refractory and severe ulcerative colitis (UC) cases. The aim of this study was to identify the factors contributing to the induction of remission and to assess the endoscopic or histologic improvement rates following induction of remission by tac. Methods This study examined data from 67 UC patients treated with tac for induction of remission out of 515 patients attending Dokkyo Medical University Hospital. The primary endpoint of the study was the analysis of factors contributing to successful induction of remission treatment with tac. The secondary endpoints were the corticosteroid-free remission rate at 52 weeks after tac induction and the endoscopic and histologic improvement rates following induction of remission. Results Analysis of factors contributing to successful induction of remission by tac showed the Lichtiger index at the beginning of remission induction therapy was 9.5 ± 2.5 for the successful remission group and 11.5 ± 2.4 for the unsuccessful remission group (p = 0.002). The proportions of patients who had used immunomodulators were 13/45 (28.9%) for the successful remission group and 14/22 (63.6%) for the unsuccessful remission group (p = 0.006). The proportions of patients who had used anti-tumor necrosis factor (TNF)α biologics were 4/45 (8.9%) for the successful remission group and 8/22 (36.4%) for the unsuccessful remission group (p = 0.006). Conclusion Patients with UC who are potential candidates for intensification of remission maintenance therapy are good candidates for induction of remission with tac. Moreover, improvement in endoscopic inflammation might be a predictive marker of response to remission induction therapy with tac.

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
