Insights

Anti-tumor necrosis factor (TNF) therapies are vital for inflammatory bowel diseases. This review explores why some patients lose response to anti-TNF drugs and how to optimize treatment using therapeutic drug monitoring.

Area of Science:

  • Gastroenterology
  • Immunology
  • Pharmacology

Background:

  • Anti-tumor necrosis factor (TNF) therapy has transformed inflammatory bowel disease (IBD) management.
  • A substantial number of patients exhibit primary non-response or secondary loss of response to anti-TNF agents.
  • Therapeutic drug monitoring (TDM) is increasingly utilized to understand and manage loss of response.

Purpose of the Study:

  • To review predictors of efficacy and outcomes for anti-TNF therapy in IBD.
  • To elucidate the mechanisms underlying anti-TNF/biological failure in Crohn's disease.
  • To identify strategies for optimizing biological treatment in IBD patients.

Main Methods:

  • Literature review of studies on anti-TNF therapy in inflammatory bowel diseases.
  • Analysis of data on predictors of response and non-response.
  • Examination of mechanisms of therapeutic failure.
  • Synthesis of strategies for treatment optimization.

Main Results:

  • Predictors of anti-TNF efficacy and outcomes vary.
  • Multiple mechanisms contribute to anti-TNF/biological failure.
  • Therapeutic drug monitoring aids in identifying causes of non-response.

Conclusions:

  • Optimizing anti-TNF therapy requires understanding individual patient responses.
  • Identifying mechanisms of failure through TDM can guide treatment adjustments.
  • Personalized strategies are crucial for improving outcomes in IBD patients treated with biologics.

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...

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...

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.

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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
