a Retrospective Study on the Systemic Treatment of LPP and FFA

Cicatricial Alopecia: a Retrospective Study on the Systemic Treatment of Lichen Planopilaris and Frontal Fibrosing Alopecia

This retrospective study aims to assess the effectiveness of systemic treatments for lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) in patients treated at the Erasmus MC University Medical Center. LPP and FFA are chronic inflammatory hair disorders leading to irreversible hair loss. The study evaluates treatment responses to systemic medications, including hydroxychloroquine, methotrexate, cyclosporine A, and retinoids.

Cicatricial alopecia, also known as scarring alopecia, refers to a group of rare chronic inflammatory hair disorders resulting in irreversible hair loss. Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are the most common forms of primary lymphocytic cicatricial alopecia, affecting predominantly postmenopausal women. These conditions lead to significant quality of life impairment due to their chronic nature and the lack of effective, standardized treatment protocols. The study aimed to address the gap in evidence-based treatment guidelines by investigating the effectiveness of various systemic therapies currently used in clinical practice. The retrospective cohort study reviewed medical records of patients diagnosed with LPP or FFA at the Department of Dermatology, Erasmus MC University Medical Center, from July 2016 to July 2022.

Inclusion Criteria:

• Diagnosis of LPP or FFA
• 18 years or older

Exclusion Criteria:

• Other forms of cicatricial alopecia than LPP or FFA
