Inflammation & Allergy Drug Targets
|July 8, 2014
Summary
Biological drugs offer new hope for ANCA-associated vasculitides (AAV) treatment. Rituximab shows promise for remission induction, while other agents like mepolizumab may benefit specific AAV subtypes.
Area of Science:
- Rheumatology and Immunology
- Internal Medicine
- Pharmacology
Background:
- Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are severe, potentially fatal necrotizing conditions.
- Current treatments (glucocorticoids and cyclophosphamide) have significant toxicity and limited efficacy in refractory/relapsing cases.
Purpose of the Study:
- To review the efficacy and application of biological agents in treating AAV.
- To identify safer and more effective therapeutic alternatives for AAV management.
Main Methods:
- Literature review focusing on biological drug therapies for AAV.
- Analysis of clinical trial data and published studies on agents like Rituximab, anti-TNF-α, Mepolizumab, and Omalizumab.
Main Results:
- Rituximab is a viable alternative to cyclophosphamide for remission induction in microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA).
- Anti-TNF-α agents have mixed results, suitable for select refractory/relapsing cases.
- Mepolizumab and Omalizumab show potential benefits for eosinophilic granulomatosis with polyangiitis (EGPA).
Conclusions:
- Biological therapies, particularly Rituximab, represent a significant advancement in AAV treatment.
- Further research is needed to define the optimal role of various biological agents across different AAV subtypes.

872
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...

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...

01:29Autoimmune Disorders
2.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

689
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...
