Autoimmune progesterone dermatitis: Update and insights

Area of Science:

• Dermatology
• Immunology
• Endocrinology

Background:

• Autoimmune progesterone dermatitis (APD) is a rare hypersensitivity reaction to endogenous progesterone fluctuations.
• It manifests with a diverse range of dermatological symptoms, including urticaria, eczema, and vesiculobullous eruptions.
• The underlying pathogenic mechanisms of APD are not fully understood.

Purpose of the Study:

• To conduct a comprehensive literature review of Autoimmune Progesterone Dermatitis (APD).
• To evaluate existing theories regarding the pathogenesis of APD.
• To assess the efficacy of different treatment modalities for APD.

Main Methods:

• A systematic review of English-language literature was performed.
• Databases searched included PubMed, EMBASE, and MEDLINE.
• Eighty-nine patient cases were included in the analysis.

Main Results:

• Symptom onset correlated with the menstrual cycle in 73% of patients.
• Hormone therapy or pregnancy preceded symptom onset in some cases.
• Diagnosis was often confirmed via intradermal progesterone sensitivity testing; treatments included anovulation induction, oral contraceptives, estrogen, and hysterectomy.

Conclusions:

• APD likely comprises multiple subsets given the varied clinical presentations, histology, and treatment responses.
• Progesterone level fluctuations may impact clinical presentation and immunological responses.
• Further research into APD pathogenesis is crucial for developing effective treatments.
