Biopsy reveals very few hair follicles which are dilated and without hairs, absence of inflammatory infiltrate, and small keratinous cysts (atrichia with horn cysts) Clinical examination reveals almost complete absence of hair and numerous papular lesions in the face, on ellbows, and knesse (atrichia with papular lesions) Ahmad et al.

Alopecia areata universalis elicited during treatment with adalimumab. Dermatology 2008;216:320-3 Treatment of Alopecia Areata: What is the Evidence? „17 trials ... with a total of 540 participants. Each trial included 6-85 participants and assessed a range of interventions that included: topical and oral corticosteroids, topical ciclosporin, photodynamic therapy, topical minoxidil. None showed significant treatment benefit in terms of hair growth when compared with placebo.“ „Few treatments have been well evaluated in randomised trials. We found no RCTs on the use of DCP, DNCB, intralesional corticosteroids or dithranol, although commonly used. Although topical steroids and minoxidil are widely prescribed and appear to be safe, there is no convincing evidence that they are beneficial in the long-term. Most trials have been reported poorly and are so small that any important clinical benefits are inconclusive. „Considering the possibility of spontaneous remission especially for those in the early stages of the disease, the options of not being treated therapeutically or, depending on individual preference wearing a wig may be alternative ways of dealing with this condition.“ Delamere et al.

Int J Dermatol 1998;37:617-621 Evolving Therapies for Alopecia Areata Genetics Epigenetics Cell Dynamics Molecular Interaction Network Disease New drug treatment opportunities based on the results of a genome-wide association study, which implicate T cell and natural killer (NK)-cell activation pathways, are leading to new approaches in future clinical trials of alopecia areata. Special attention is being given to the UL 16-binding protein (ULBP3) gene cluster on chromosome 6q25, as these genes make the NKG2D-activating ligand or signal that can trigger the NKG2D receptor, initiating an autoimmune response. Petukhova et al. Genome-wide association study in alopecia areata implicates both innate and adaptive immunity. Nature. 2010 Jul 1;466(7302):113-7. A greater expression of ULBP3 has been found in hair follicles in scalp biopsy specimens from patients with active disease. It is now postulated that the characteristic T cell "swarm of bees" infiltrate seen in alopecia areata is the result of T cells being attracted to the hair follicle by NKG2D-activating ligands. Complexity in pathogenesis may be an opportunity in terms of targeting the disease therapeutically: Future treatment approaches for alopecia areata include use of drugs that: (i) block the NKGD-activating ligand and NKG2D receptor interaction, (ii) halt activated T cells, or (iii) modify the inflammatory cytokine network. Drugs currently being used or being evaluated for other autoimmune diseases that work through these mechanisms might prove to be very effective in alopecia areata: - CTLA4-Ig fusion protein (Abatacept) - anti-IL15Rmab - (Janus Kinase) JAK3-inhibitor (Tofacitinib) - JAK1/2-inhibitor (Ruxolitinib) blocks co-stimulation of T-cells blocks activation of CD8+ T-cells blocks signal transduction (IL-15R) blocks signal transduction (IL-15R) Hordinsky MK.
