Insights

Interleukin-1 blockade therapy with anakinra shows promise for treating refractory giant cell arteritis. This approach improved symptoms and inflammation markers in patients unresponsive to standard treatments.

Area of Science:

  • Rheumatology
  • Immunology
  • Vascular Medicine

Background:

  • Giant cell arteritis (GCA) is a large-vessel vasculitis causing arterial inflammation and occlusion.
  • Current treatments like glucocorticoids often lead to relapses and complications.
  • Limited options exist for refractory GCA cases.

Observation:

  • Interleukin-1 beta (IL-1β) is elevated in inflamed arteries of GCA patients.
  • Anakinra, an IL-1 blockade therapy, was administered to three refractory GCA patients.
  • Treatment outcomes were assessed via clinical symptoms, inflammatory markers, and imaging.

Findings:

  • Anakinra successfully treated all three refractory GCA patients.
  • Patients experienced improved symptoms and reduced inflammation biomarkers.
  • Two patients showed a complete resolution of arterial inflammation on PET/CT scans.

Implications:

  • IL-1β blockade represents a potential novel therapeutic strategy for refractory GCA.
  • Anakinra may offer an effective alternative for patients with limited treatment options.
  • Further research is warranted to confirm anakinra's efficacy and safety in larger GCA cohorts.

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),...

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),...

Drugs Acting on Autonomic Ganglia: Blockers

Ganglionic blockers inhibit autonomic activity by blocking nicotinic receptors in the autonomic ganglia, suppressing impulse transmission. These blockers lack selectivity between sympathetic and parasympathetic ganglia and are ineffective as neuromuscular junction antagonists. They can be categorized into two groups:
T Cell Types and Functions01:24

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...

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 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...
