Learning from serum markers reflecting endothelial activation: longitudinal data in childhood-onset systemic lupus erythematosus.

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
objectivesIn childhood-onset SLE (cSLE), patients have an increased risk of premature atherosclerosis. The pathophysiological mechanisms for this premature atherosclerosis are not yet completely understood, but besides traditional risk factors, the endothelium plays a major role. The first aim of this study was to measure levels of SLE-associated markers involved in endothelial cell (EC) function and lipids in a cSLE cohort longitudinally in comparison with healthy controls (HC). Next aim was to correlate these levels with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and nailfold capillaroscopic patterns.
methodsBlood serum samples, videocapillaroscopy images and patient characteristics were collected in a multicentre longitudinal cSLE cohort and from age and sex comparable HC. Disease activity was evaluated by SLEDAI. A total of 15 EC markers and six lipids were measured in two longitudinal cSLE samples (minimum interval of 6 months) and in HC. Nailfold videocapillaroscopy images were scored according to the guidelines from the EULAR Study Group on Microcirculation in Rheumatic Diseases.
resultsIn total, 47 patients with cSLE and 42 HCs were analysed. Median age at diagnosis was 15 years (IQR 12-16 years). Median time between t=1 and t=2 was 14.5 months (IQR 9-24 months). Median SLEDAI was 12 (IQR 6-18) at t=1 and 2 (IQR 1-4) at t=2. Serum levels of angiopoietin-2, CCL2, CXCL10, GAS6, pentraxin-3, thrombomodulin, VCAM-1 and vWF-A2 were elevated in cSLE compared with HC at t=1. While many elevated EC markers at t=1 normalised over time after treatment, several markers remained significantly increased compared with HC (angiopoietin-2, CCL2, CXCL10, GAS6, thrombomodulin and VCAM-1).
conclusionIn serum from patients with cSLE different markers of endothelial activation were dysregulated. While most markers normalised during treatment, others remained elevated in a subset of patients, even during low disease activity. These results suggest a role for the dysregulated endothelium in early and later phases of cSLE, possibly also during lower disease activity. TRIAL REGISTRATION NUMBER: NL60885.018.17.
