Insights

Mycophenolate mofetil (MMF) showed less efficacy than cyclosporin for severe psoriasis control in a small patient group. However, MMF improved renal function in patients with cyclosporin-induced nephrotoxicity.

Area of Science:

  • Dermatology
  • Nephrology
  • Immunosuppression

Background:

  • Long-term cyclosporin use for severe psoriasis can lead to nephrotoxicity and hypertension.
  • Alternative immunosuppressants are needed for patients intolerant to cyclosporin.

Purpose of the Study:

  • To evaluate the efficacy and safety of switching from long-term cyclosporin to mycophenolate mofetil (MMF) in patients with severe psoriasis.

Main Methods:

  • Eight patients with severe psoriasis on long-term cyclosporin were switched to MMF.
  • Reasons for switching included nephrotoxicity (n=7) and lack of efficacy/hypertension (n=1).
  • Psoriasis control and renal function were monitored post-switch.

Main Results:

  • Psoriasis control significantly deteriorated in 5 patients and slightly in 3.
  • Renal function improved in 6 of 6 patients with pre-existing nephrotoxicity after >2 weeks on MMF.
  • MMF provided reasonable disease control in 3 of 8 patients.

Conclusions:

  • Mycophenolate mofetil (MMF) appears less effective than cyclosporin for severe psoriasis control.
  • MMF may be a viable alternative for patients with psoriasis who cannot tolerate cyclosporin due to renal toxicity.
  • MMF demonstrated potential for improving renal function in patients with prior cyclosporin-induced nephrotoxicity.

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation.

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...

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),...

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.

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
