Insights

The protein C (PC) pathway is defective in inflammatory bowel disease (IBD) patients, contributing to hypercoagulability. This defect is linked to inflammation and observed in both active and inactive disease stages.

Area of Science:

  • Hematology
  • Gastroenterology
  • Immunology

Background:

  • Inflammatory bowel disease (IBD) involves an imbalance in hemostatic factors.
  • Deficiencies in the protein C (PC) pathway can worsen thrombosis and inflammation in IBD.

Purpose of the Study:

  • To evaluate protein C (PC) pathway components in IBD patients.
  • To determine correlations between PC system components and IBD disease activity.

Main Methods:

  • Measured levels of PC, free protein S (PS), and soluble thrombomodulin (sTM) in patients with ulcerative colitis (UC) and Crohn's disease (CD), and healthy controls.
  • Assessed correlations between PC system components, disease activity, hemostatic variables, and inflammatory markers.

Main Results:

  • Elevated sTM levels in UC patients compared to controls.
  • Higher PC activity and lower PS activity observed in IBD patients versus controls.
  • PC levels correlated with UC disease activity, but inflammatory markers (TNF-α, IL-6) did not correlate with PC system components.

Conclusions:

  • The protein C (PC) pathway is impaired in both Crohn's disease (CD) and ulcerative colitis (UC).
  • Hypercoagulability in IBD may stem from inflammation and anticoagulant system disturbances.
  • Defective PC pathway function is present regardless of disease activity in IBD.

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.

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 colonic...

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...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

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 (COX-2),...
