Deucravacitinib Treatment for Psoriasis Complicated by Myelodysplastic Syndrome Without Exacerbation of the Underlying Hematologic Disorder: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Psoriasis is a chronic, immune-mediated inflammatory skin disease associated with systemic comorbidities such as cardiovascular disease and autoimmune disorders. Deucravacitinib, a selective oral tyrosine kinase 2 (TYK2) inhibitor, has demonstrated strong efficacy and safety in the treatment of psoriasis. However, its use in patients with hematologic malignancies, such as myelodysplastic syndrome (MDS), has not been thoroughly investigated. We report the case of a 73-year-old man with psoriasis vulgaris complicated by MDS and chronic kidney disease (CKD). The patient had a long-standing history of psoriasis managed with topical therapies but experienced an acute flare, presenting with erythema, scaling, and pustules involving over 40% of the body surface area (Psoriasis Area and Severity Index (PASI) score: 28.8). Given his underlying MDS and the need for a safe therapeutic option, deucravacitinib (6 mg once daily) was initiated. Over eight months of treatment, the patient's skin lesions markedly improved, achieving a PASI 75 response with a final PASI score of 4.6. No adverse effects or signs of MDS progression were observed. Moreover, his anemia remained well controlled without the need for monthly darbepoetin alfa injections. This case highlights the potential of deucravacitinib as a safe and effective treatment option for psoriasis patients with concurrent MDS. Given the emerging understanding of TYK2 as an oncogenic driver in myeloproliferative diseases, further studies are warranted to clarify the therapeutic implications of TYK2 inhibition in this patient population.
