Autoimmune Hormonal Dermatitis Mechanisms
Summary
Autoimmune hormonal dermatitis encompasses a group of cutaneous disorders driven by aberrant immune responses to endogenous hormones, predominately progesterone. Patients typically experience cyclic eruptions—urticaria, eczema, erythema multiforme and angioedema—coinciding with the luteal phase of the menstrual cycle. Mechanistic studies implicate both immediate (Type I) and delayed (Type IV) hypersensitivity reactions in which progesterone serves as a hapten, triggering mast cell degranulation, IgE synthesis and T-cell activation. Hormonal modulation during pregnancy and following exogenous administration further underscores the interplay between endocrine and immune networks. Breakdown of peripheral tolerance to steroid hormones, shifts in cytokine profiles and dysregulated antigen presentation have been identified as central to lesion formation. Greater insight into these pathways has informed targeted therapies, ranging from ovulation suppression and systemic antihistamines to monoclonal antibodies, offering durable remission while minimising systemic side effects. Recognition of hormonal dermatitis has global significance, given its impact on quality of life and the potential for misdiagnosis.

Autoimmune Hormonal Dermatitis Mechanisms publication trend
The graph below shows the total number of articles in autoimmune hormonal dermatitis mechanisms across all publications each year (not limited to Nature Index journals).
Technical terms
Autoimmune progesterone dermatitis (APD): A cyclic dermatosis characterised by hypersensitivity reactions to endogenous progesterone, manifesting as skin eruptions during the luteal phase.
Type I hypersensitivity: An immediate allergic response mediated by IgE, leading to mast cell degranulation and histamine release.
Type IV hypersensitivity: A delayed immune response driven by T lymphocytes, resulting in tissue inflammation and delayed-onset lesions.
Luteal phase: The post-ovulatory phase of the menstrual cycle during which progesterone levels peak.
Omalizumab: A monoclonal antibody targeting IgE, used to mitigate allergic and hypersensitivity conditions.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
