Evaluation of serum presepsin, procalcitonin, copeptin, and high-sensitivity C-reactive protein for differentiating bacterial infection from disease activity in Egyptian patients with systemic lupus erythematosus.
Observational study in Clinical rheumatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectivesSeveral biological markers have been studied for the differentiation of infection from disease activity in systemic lupus erythematosus (SLE) patients with discrepant results. We aimed to evaluate the role of serum presepsin, hs-CRP, procalcitonin (PCT), and copeptin (CPP) in differentiating bacterial infections from disease activity in SLE patients.
methodsThis study is a cross-sectional observational study in which 94 Egyptian patients were recruited from June 2017 to January 2018. Our patients were divided into two groups: group (1) included 48 patients with active SLE hospitalized with any sort of lupus activity and group (2) included 46 patients with active SLE admitted with a proven bacterial infection. Hs-CRP, presepsin, PCT, and CPP were measured using enzyme-linked immune sorbent assay technique.
resultsHs-CRP, presepsin, PCT, and CPP were highly significantly higher among group (2) patients compared to group (1) patients (p < 0.001). Serum presepsin expressed higher specificity than hs-CRP (87.5% vs 60.4%) but the same sensitivity (80.4%) in the detection of bacterial infection in SLE patients. Serum PCT expressed higher specificity than hs-CRP (100% vs 60.4%) but lower sensitivity (73.9% vs 80.4%). Serum CPP expressed higher specificity than hs-CRP (65.9% vs 60.4%) but lower sensitivity (65.9% vs 80.4%).
conclusionOur study suggests that increased serum levels of hs-CRP, presepsin and PCT levels are useful in differentiating bacterial infections from disease activity in SLE patients. Serum CPP could be used as an adjunct with more specific inflammatory biomarkers in making better diagnostic judgments. KEY POINTS: • The increased serum levels of hs-CRP, presepsin and PCT levels are useful in differentiating bacterial infections from disease activity in SLE patients. • Serum Presepsin expressed higher specificity than hs-CRP but the same sensitivity in the detection of bacterial infection in SLE patients. • Serum CPP expressed higher specificity than hs-CRP but lower sensitivity.
