          Abstract

          Baricitinib is an oral selective Janus kinase 1/2 inhibitor that has achieved clinically meaningful outcomes for scalp, eyebrow, and eyelash hair regrowth in patients with severe alopecia areata (AA) at week 36 of treatment. Treatment with baricitinib, 4 mg, has resulted in higher response rates than baricitinib, 2 mg, at weeks 36 and 52.

          Alopecia areata

          Alopecia areata is an autoimmune disorder characterized by transient, non-scarring hair loss and preservation of the hair follicle. Hair loss can take many forms ranging from loss in well-defined patches to diffuse or total hair loss, which can affect all hair-bearing sites. Patchy alopecia areata affecting the scalp is the most common type. Alopecia areata affects nearly 2% of the general population at some point during their lifetime. Skin biopsies of affected skin show a lymphocytic infiltrate in and around the bulb or the lower part of the hair follicle in the anagen (hair growth) phase. A breakdown of immune privilege of the hair follicle is thought to be an important driver of alopecia areata. Genetic studies in patients and mouse models have shown that alopecia areata is a complex, polygenic disease. Several genetic susceptibility loci were identified to be associated with signalling pathways that are important to hair follicle cycling and development. Alopecia areata is usually diagnosed based on clinical manifestations, but dermoscopy and histopathology can be helpful. Alopecia areata is difficult to manage medically, but recent advances in understanding the molecular mechanisms have revealed new treatments and the possibility of remission in the near future.

              Health-related quality of life (HRQoL) among patients with alopecia areata (AA): A systematic review

              Alopecia areata (AA) is a common skin disease that is frequently emotionally devastating. Several studies have examined the effect of AA on health-related quality of life (HRQoL). We performed a systematic review of all published studies of HRQoL in patients with AA. Eleven studies met inclusion criteria, incorporating data from 1986 patients. Patients with AA consistently demonstrate poor HRQoL scores, with greater extent of scalp involvement associated with lower HRQoL. HRQoL experienced by patients with AA is similar to that seen in patients with other chronic skin diseases including atopic dermatitis and psoriasis.
