Combined Microneedling With Either 1% Lactic Acid Solution or Vitamin D3 or Triamcinolone Acetonide in The Treatment of Alopecia Areata

Alopecia areata (AA) is an immunologically mediated disease characterized by non-scarring hair loss (Madni and Shapiro, 2000). AA is presented by rapid and complete hair loss in one or more round or oval patches, usually on the scalp, beard area, eyebrows, eyelashes, and less commonly, on other hairy areas of the body (Berker et al., 2010 and James et al., 2011) Alopecia areata is a T-cell-mediated autoimmune disease. There is a complicated interplay between loss of immune privilege in the hair follicle, autoimmune-mediated hair follicle damage, and activation of inflammatory pathways that have been argued to explain the development of this disorder, but the exact pathophysiology of AA remains unknown. Hair follicles are infiltrated by autoreactive CD8 and CD4 T lymphocytes, which attack hair follicle-derived autoantigens while sparing the stem compartment (Rajabi et al., 2018). Alopecia areata can be treated with topical and/or intralesional corticosteroids, which are the treatment of choice. Anthralin, minoxidil, coal tar, and topical immunotherapy are examples of other topical treatments. Systemic immunosuppressants such as cyclosporine, systemic steroids, Janus kinase inhibitors, and methotrexate may be considered in severe resistant cases (lee and lee, 2017). Intralesional triamcinolone acetonide is preferred in cases of AA , as it is well known as anti-inflammatory and interferes with local immunity of the skin, which helps in the recovery of the disease, but if used …
