Plasma proteomics in patients with von Willebrand disease and hemophilia A highlights von Willebrand factor as main determinant of response to desmopressin treatment.

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
Background: Desmopressin, 1-deamino-8-D-arginin vasopressin (DDAVP), is a treatment option for people with von Willebrand disease (VWD) and hemophilia A (HA) with a large interindividual variation in response. DDAVP elicits the release of von Willebrand Factor (VWF) from endothelial cells, thereby increasing the levels of circulating VWF and coagulation factor (F)VIII. However, we currently lack detailed insight on additional systemic effects of DDAVP administration on plasma protein levels. Objectives: This study aimed to investigate plasma proteomic profiles associated with DDAVP administration. Methods: Longitudinal plasma samples of 13 patients with VWD and 9 people with mild HA up to 24 hours after DDAVP infusion were analyzed using mass spectrometry-based proteomics. Results: Among 408 proteins quantified in plasma, only VWF and VWF propeptide (pp) increased significantly at 1 and 2 hours after DDAVP infusion in people with HA and VWD, respectively. VWF antigen levels were in agreement with mass spectrometry-based VWF intensity levels ( Conclusion: This study showed the selective increase of VWF and VWFpp 1 to 2 hours after DDAVP infusion and highlighted the interindividual variance in VWF clearance. Additionally, a delayed acute-phase response in a subgroup of patients suggested the potential role of inflammatory mechanisms contributing to heterogeneity of response.
