Blood ACE Activity Is Significantly Lowered in Psoriasis Compared to Atopic Dermatitis: A Small Pilot Study in Young Males.
Article in Current medical science, 2026. 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
purposeEmerging evidence suggests the involvement of the renin-angiotensin system (RAS) in the pathogenesis and progression of autoimmune dermatological diseases. In a small exploratory study, we investigated angiotensin-converting enzyme (ACE) activity in blood obtained from male probands with psoriasis vulgaris (n = 4) and atopic dermatitis (AD, n = 5).
methodsThe degradation capacity of dabsylated synthetic bradykinin (DBK) with and without inhibition was determined using a thin-layer chromatography (TLC)-based neuropeptide reporter assay.
resultsWe observed a significantly reduced capacity for cleavage of DBK in psoriasis patients compared with that in AD patients and controls. In patient samples, the variation in the measured values was generally greater than that in healthy controls. We could not confirm the increased ACE activity in the circulation in psoriasis patients reported by others, likely because of different study designs and detection methods. We did not include samples of female patients and focused on younger men to avoid hormonal effects and minimize age-related factors.
conclusionThis preliminary study of the hypothesis-generating nature lacks power, but it certainly adds a question to the current view of the role of ACE in psoriasis. Treatments targeting specific components of the RAS could ameliorate inflammatory responses; thus, research in this area is becoming increasingly important.
