A New Perspective on Isotretinoin Treatment of Hidradenitis Suppurativa: A Retrospective Chart Review of Patient Outcomes
Bibliographic record
Abstract
BACKGROUND: Hidradenitis suppurativa (HS) is a disease characterized by the development of painful, deep-seeded nodules and abscesses. Treatment guidelines include a combination of lifestyle, surgical, and medical interventions. Isotretinoin has not been included in the treatment guidelines due to the limited number of studies and conflicting reports of efficacy. OBJECTIVES: The purpose of this study is to evaluate the clinical response to isotretinoin in HS patients and to determine whether there is a particular patient population that may benefit more from this treatment. METHODS: A retrospective chart review was conducted on all HS patients treated with isotretinoin within the years of 2014-2016. Sex, age, weight, history of acne, Hurley stage, and treatment dose and duration were extracted from patient charts. RESULTS: Of the 25 patients included in the study, 32% (8/25) had no response, 32% (8/26) showed partial response, and 36% (9/25) demonstrated complete response to isotretinoin treatment. Complete response was seen only in Hurley stage I and II patients. Hurley III patients made up 50% of the non-responders. Those with any sort of treatment response were more likely to be female, younger, weigh less, and have a higher prevalence of acne compared to non-responders. LIMITATIONS: This is a retrospective chart review with a small sample size of 25 patients. CONCLUSIONS: Physicians should consider isotretinoin as a potential treatment for HS, as it may be beneficial in patients with mild and moderate disease and patients who are female, younger, weigh less, and have a personal history of acne.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
