Awareness of isotretinoin use and safety in Saudi Arabia: A nationwide cross-sectional study

Report of successful treatment of follicular occlusion triad with adalimumab and research progress on biologic therapy for follicular occlusion triad

Purpose: This article aims to present a case report of a patient with Follicular occlusion triad (FOT) who achieved successful disease control with adalimumab combined with isotretinoin and provide a comprehensive review of the current research progress on biologic therapies for FOT.

Methods: We report a case of a 22-year-old female patient diagnosed with FOT, who was treated with adalimumab combined with isotretinoin after failing to respond to conventional therapies. A systematic literature review was conducted to summarize the current research progress on biologic therapies for FOT, including TNF-α inhibitors, IL-17 inhibitors, IL-12/IL-23 inhibitors, IL-23 inhibitors, IL-1 inhibitors, and other novel biologic agents.

Results: The patient achieved significant improvement in skin lesions, pain, and quality of life after three months of treatment with adalimumab combined with isotretinoin, without experiencing severe adverse reactions. The literature review revealed that adalimumab and secukinumab are the two FDA-approved biologics for FOT, while others, such as bimekizumab, infliximab, anakinra, and bermekimab, have shown promise in clinical studies.

Conclusions: Biologic therapies have revolutionized FOT management, providing effective options for patients unresponsive to conventional treatments. As our understanding of FOT pathogenesis and the mechanisms of action of biologics grows, further advancements in biologic therapies for FOT are expected.

Isotretinoin-Related Eye Dryness in Acne Patients in Qassim, Saudi Arabia

Background Isotretinoin is a commonly prescribed agent mainly used to treat acne vulgaris. Since its Food and Drug Administration (FDA) approval, the subject of its associations with various medical conditions has become a growing interest in many investigational studies. Methodology A retrospective study was conducted using the validated Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaire. All statistical calculations were performed using the Statistical Package for the Social Sciences (SPSS) version 27.0.1 (IBM SPSS Statistics, Armonk, NY). Results The research study involved 107 participants, predominantly Saudi nationals (98.1%), with an average age of 22 years. Regarding the total cumulative dose (TCD), 40.2% had less than 50 mg/kg, 33.6% had between 50 and 100 mg/kg, and 15.9% had more than 100 mg/kg. The majority (73.8%) did not stop using isotretinoin. The average Ocular Surface Disease Index (OSDI) score, indicating ocular surface disease symptoms, was 26.78. There was no significant association between gender, dose/duration of isotretinoin, TCD, and age, and OSDI scores. However, participants with severe OSDI scores were more likely to have worsened pre-existing eye symptoms compared to those with non-severe OSDI scores (35.1% versus 11.4%, p = 0.011). Conclusions This study contributes to the understanding of the impact of isotretinoin usage on ocular surface health. While no significant associations were found between gender, dose, duration, TCD, and age, and OSDI scores, participants with pre-existing eye symptoms were more likely to experience worsened symptoms during isotretinoin treatment.
