Insights

Tumor Necrosis Factor-alpha (TNFa) antagonists are effective for chronic inflammatory diseases but increase infection risk. Proactive screening for latent tuberculosis and monitoring for leucopenia are crucial for patient safety.

Area of Science:

  • Immunology
  • Pharmacology
  • Infectious Diseases

Background:

  • Tumor Necrosis Factor-alpha (TNFa) antagonists are established treatments for severe chronic inflammatory conditions.
  • Clinical use has revealed an increased risk of adverse events, particularly infections, associated with TNFa antagonists.
  • A practical approach is needed for the prevention and management of infections in patients receiving TNFa antagonists.

Purpose of the Study:

  • To outline strategies for preventing and monitoring infections in patients treated with TNFa antagonists.
  • To highlight the increased susceptibility to intracellular pathogens, including tuberculosis, with TNFa antagonist therapy.
  • To propose guidelines for managing infectious risks associated with TNFa antagonist use.

Main Methods:

  • Review of clinical data and established guidelines regarding TNFa antagonist therapy and infectious complications.
  • Emphasis on pre-treatment screening for latent tuberculosis infection (LTBI).
  • Recommendations for prophylactic measures and ongoing patient monitoring.

Main Results:

  • TNFa antagonists significantly elevate the risk of infections, especially those caused by intracellular pathogens.
  • Screening for latent tuberculosis infection prior to initiating TNFa antagonist treatment is essential.
  • Prophylaxis for LTBI is indicated in positive cases.
  • Minimizing global infectious risk involves optimal vaccination coverage and regular leucopenia screening.

Conclusions:

  • Proactive management of infectious risks is paramount for patients undergoing TNFa antagonist therapy.
  • Pre-treatment screening for latent tuberculosis and subsequent prophylaxis are critical.
  • Maintaining optimal vaccination status and monitoring for leucopenia further mitigate infection risks.

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 (Humira),...

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.

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

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 Disease...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
