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

1.1K
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 IV: Pharmacological Management

994
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 Immunomodulatory Agents

726
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 Glucocorticoids

685
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...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Area of Science:

  • Immunology
  • Gastroenterology
  • Dietary Science

Background:

  • Celiac disease requires a lifelong gluten-free diet (GFD) due to gluten's immunogenicity, even in small amounts.
  • Patient adherence to GFD is crucial for managing celiac disease, necessitating expert dietary counseling.

Purpose of the Study:

  • To review current and emerging therapeutic targets for celiac disease beyond the standard GFD.
  • To evaluate the potential of novel treatments as adjunctive therapies to the GFD.

Main Methods:

  • Literature review of current and investigational treatments for celiac disease.
  • Analysis of therapeutic targets including dietary modifications, enzymatic gluten degradation, and immune system modulation.
  • Examination of clinical trial progress for emerging therapies.

Main Results:

  • Several novel therapeutic targets are under investigation, including ancient wheat varieties, prolylendopeptidases, zonulin antagonists, HLA-DQ2 blockers, and immune modulators.
  • Some promising approaches, such as zonulin antagonists and endopeptidases, have advanced to Phase II and III clinical trials.
  • Most novel therapies are anticipated to serve as adjunctive treatments rather than replacements for the GFD.

Conclusions:

  • While the gluten-free diet remains the cornerstone of celiac disease management, ongoing research offers promising adjunctive therapeutic strategies.
  • Future treatments may enhance gluten degradation, reduce peptide passage, or modulate the immune response, potentially improving quality of life for celiac patients.
