Официальное название
Assessment of Janus Kinase 2 Expression in Patients With Androgenic Alopecia and Its Modulation by Topical Minoxidil Therapy.
Обзор
Androgenetic alopecia is a common form of progressive hair loss. This prospective single-arm pre-post interventional study aims to assess tissue Janus Kinase 2 (JAK2) expression in patients with androgenetic alopecia by comparing balding and non-balding scalp at baseline, and to evaluate changes in JAK2 expression in balding scalp after 3 months of topical minoxidil 5% therapy. Clinical response will be assessed using standardized trichoscopic parameters.
Подробное описание
This study will recruit 25 adult patients aged 18 to 50 years with mild to moderate androgenetic alopecia attending the Dermatology outpatient clinic, Cairo University Hospital. At baseline, participants will undergo clinical evaluation, standardized photography, and trichoscopic assessment. Three 2 mm scalp punch biopsies will be obtained over the course of the study: one from the balding scalp area and one from the non-balding scalp area at baseline, and one from the balding area after 3 months of therapy. Tissue JAK2 protein levels will be measured by ELISA. Participants will receive topical minoxidil 5% solution for 3 months (1 cc twice daily for men and once daily for women). The primary endpoint is the comparison of tissue JAK2 levels between balding and non-balding scalp at baseline. Secondary analyses will assess change in JAK2 levels after treatment and correlations with clinical improvement by trichoscopy.
Вмешательства
- Препарат Topical Minoxidil 5% Solution
Topical minoxidil 5% solution applied to the affected scalp areas for 12 weeks. Men will apply 1 cc twice daily and women will apply 1 cc once daily. - Процедура Scalp Punch Biopsy
Three 2 mm punch biopsies will be obtained during the study: one from the balding scalp area and one from the non-balding scalp area at baseline, and one from the balding scalp area after 12 weeks of treatment. - Диагностический тест Tissue JAK2 Protein Measurement by ELISA
Tissue samples obtained from scalp punch biopsies will be analyzed for Janus Kinase 2 (JAK2) protein levels using ELISA at baseline and after 12 weeks of treatment.
