Abstract

fetched live from OpenAlex

BACKGROUND: Patients with severe chronic hand eczema (CHE) often respond to therapy with oral alitretinoin (9-cis retinoic acid). However, the efficacy of alitretinoin after disease relapse has not been demonstrated. OBJECTIVES: To assess the efficacy and safety of a second course of oral alitretinoin in patients with severe CHE who relapsed after achieving 'clear' or 'almost clear' hands following a previous course of alitretinoin. METHODS: The double-blind study included 117 patients with CHE who had responded to therapy in an earlier clinical trial and subsequently relapsed. Patients were randomized to receive their previous treatment or placebo. Treatment was alitretinoin 30 mg or 10 mg or placebo given once daily for 12-24 weeks. Response was defined as an overall Physician's Global Assessment rating of 'clear' or 'almost clear' hands at the end of therapy. RESULTS: Response rates were 80% in patients retreated with 30 mg alitretinoin compared with 8% for placebo (P < 0.001). In patients retreated with 10 mg alitretinoin response rates were 48%, compared with 10% in the placebo group. Alitretinoin was well tolerated. Adverse reactions comprised typical retinoid class effects, and no late-arising side-effects were observed during this second course of treatment. CONCLUSIONS: The majority of patients with CHE who previously achieved 'clear' or 'almost clear' hands following treatment with alitretinoin 30 mg per day also responded to a second course of treatment. Retreatment was well tolerated. Intermittent treatment with alitretinoin is suitable for the long-term management of CHE.

Teacher imitation

Not 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.
