Deucravacitinib Improved Interstitial Pneumonia Along with KL-6 Reduction in a Patient with Psoriasis: A Case Report.

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
This case report describes a patient with psoriasis and interstitial pneumonia (IP) presenting with linear opacities who was treated with deucravacitinib, aiming to highlight the potential role of deucravacitinib in improving IP. Psoriasis is a chronic immune-mediated skin disease involving T helper (Th) 17 cells, often accompanied by systemic comorbidities. Deucravacitinib, a selective oral tyrosine kinase 2 (TYK2) inhibitor targeting interleukin (IL)-23 and type I interferons, has shown strong efficacy and safety in psoriasis treatment. Interstitial pneumonia (IP) is a group of lung diseases characterized by inflammation, fibrosis, and progressive respiratory decline. Cytokines play key roles in its pathogenesis. Emerging evidence suggests that psoriasis has higher risks of IP, possibly due to shared IL-23/IL-17 pathway. The patient showed marked improvement in skin and lung findings, along with KL-6 levels after deucravacitinib treatment. TYK2 mediates downstream signaling of key pro-fibrotic and pro-inflammatory cytokines involved in IP. Therefore, we consider that deucravacitinib may have contributed to the improvement of IP by blocking these signaling pathways, thereby suppressing chronic T cell-driven inflammation and fibrosis. Further accumulation of cases and continued research will be essential in advancing discussions on the clinical utility of TYK2 inhibitors in IP management.
