Fast Itch Relief during Dupilumab Predicts Clinical Efficacy in Bullous Pemphigoid: A Retrospective Cohort Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDupilumab has emerged as a promising treatment option for bullous pemphigoid (BP). Rapid identification of responders could avoid the need for additional immunosuppressive treatments that are associated with increased morbidity and mortality.
methodsTo investigate the course of itch as an early indicator of treatment response, data of 12 BP patients treated with dupilumab at the University Hospital of Zurich were retrospectively evaluated. Disease severity was assessed by bullous pemphigoid disease area index (BPDAI) and pruritus by a numeric rating scale (NRS, 0-10) at baseline; days 1, 3, 14; months 1, 2; and the last follow-up.
resultsA total of 8/12 patients (67%) had complete response, and 4/12 patients (33%) had partial response during dupilumab treatment. Notably, a highly significant reduction of pruritus (p < 0.0001) was observed already on day 1 with further improvement at later time points. Moreover, fast relief of itch could predict treatment response with a significant correlation to clinical response on day 14 (Spearman correlation R 0.70, p value 0.025), with a positive but non-significant trend on day 3 (R 0.63, p value 0.091). Additionally, 92% (11/12 patients) were on dupilumab monotherapy at the last follow-up without any concomitant systemic or topical treatment for BP.
conclusionsThe rapid and significant decline in BP-associated pruritus observed with dupilumab correlated significantly with disease remission. Early evaluation of pruritus response could change how BP is treated in the future and avoid additional immunosuppressive treatment in BP.
