Abstract

Insights

Anakinra effectively reduces Familial Mediterranean Fever (FMF) attacks and inflammation in colchicine-resistant patients. This anti-IL-1 therapy improves quality of life and is generally safe, though some patients discontinue due to side effects or inadequate response.

Area of Science:

  • Rheumatology
  • Autoinflammatory Diseases
  • Genetics

Background:

  • Familial Mediterranean Fever (FMF) is a genetic autoinflammatory disease characterized by recurrent inflammatory attacks.
  • Colchicine is the standard treatment, but some patients are resistant or intolerant.
  • Anakinra, an anti-interleukin-1 agent, has shown promise in managing FMF in clinical trials.

Purpose of the Study:

  • To review the outcomes of FMF patients treated with anakinra due to insufficient response to colchicine at a single tertiary center.
  • To evaluate the efficacy and safety of anakinra in a real-world clinical setting for colchicine-resistant FMF.

Main Methods:

  • A retrospective review of 106 FMF patients treated with anakinra for at least one month.
  • Data collected included attack frequency, patient-reported disease severity (Visual Analogue Scale), and acute phase reactants.
  • Exclusion criteria included amyloidosis and pregnancy.

Main Results:

  • Anakinra treatment led to a significant decrease in attack frequency, with 75 patients experiencing no attacks.
  • Patient global assessment scores improved significantly (P < 0.001).
  • 32% of patients discontinued treatment due to insufficient response or side effects; all side effects were reversible.

Conclusions:

  • Anakinra is an effective and safe therapeutic option for FMF patients refractory to colchicine.
  • The drug demonstrates efficacy in preventing attacks and improving patients' quality of life.

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...

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...

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.
