Ipilimumab is a fully humanized monoclonal antibody against cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and one of a growing class of immunomodulatory therapies for melanoma. The most common toxicities are immune-related adverse effects (irAEs), which manifest most frequently in the skin as rash and pruritus. We report a case of alopecia areata (AA) attributed to ipilimumab that presented 1.5 years after treatment. Because CTLA-4 dysregulation has been increasingly linked to AA, the incidence of this irAE may increase following US Food and Drug Administration approval of a higher dose of ipilimumab for adjuvant treatment of stage III melanoma.

Alopecia areata is a prevalent autoimmune condition causing non-scarring alopecia, with significant impacts on quality of life. However, the long-term effects on major life-changing decisions remain understudied. A cross-sectional study was performed including patients with alopecia areata who attended the Dermatology Department of the Virgen de las Nieves University Hospital.

Purpose: Alopecia areata (AA) is a common, immune-mediated, non-scarring form of hair loss. Janus kinase inhibitors provide considerable insight into the treatment of severe AA. However, the efficacy and safety of upadacitinib treatment of adolescents and pediatric patients with severe AA is unclear, especially in those without concomitant atopic diseases.

Background: Bullous Pemphigoid (BP) is caused by a predominantly Th2-mediated attack on the basement membrane by the production of anti-BP180 and anti-BP230 antibodies. Malignant tumors can exacerbate immune disorders through a variety of potential pathways, including pro-inflammatory responses in the tumor microenvironment, cross-immune responses induced by tumor-associated antigens, and the lifting of immunosuppressive states and activation of underlying autoimmune responses after surgery. Alopecia Areata (AA) is an autoimmune disease caused by T-lymphocyte-mediated destruction of the immune privilege of the hair follicle, specifically involving the immune axes of Th1, Th2 and Th17.
