Alopecia universalis successfully treated with adalimumab.

|October 17, 2014
Summary
Alopecia universalis, a severe form of hair loss, was successfully treated with adalimumab, a TNF inhibitor. This challenges previous findings and suggests a complex role for TNF in alopecia areata pathogenesis.
Area of Science:
- Dermatology
- Immunology
- Pharmacology
Background:
- Alopecia universalis (AU) is an extreme form of alopecia areata (AA) characterized by complete scalp and body hair loss.
- AU is notoriously difficult to treat, with Tumor Necrosis Factor (TNF) inhibitors often proving ineffective or even exacerbating the condition.
Observation:
- A case study involving a woman in her 30s with AU, resistant to various treatments, is presented.
- Successful treatment of this refractory AU case with adalimumab, a TNF inhibitor, was achieved.
Findings:
- The successful treatment of AU with adalimumab suggests a nuanced role for TNF in AA pathogenesis.
- The interplay between TNF and other cytokines, such as interferons, may be critical in the development of AA, particularly in patients treated with TNF inhibitors.
Implications:
- Pharmacogenetic factors and individual TNF levels could explain differential responses to TNF inhibitors in AA.
- Further research is warranted to elucidate the complex mechanisms underlying AA and optimize treatment strategies involving TNF inhibitors.

734
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...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
854
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...

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...

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
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...

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
