The diagnostic significance of signal peptide-complement C1r/C1s, Uegf, and Bmp1-epidermal growth factor domain-containing protein-1 levels in pulmonary embolism.
BACKGROUND
Pulmonary embolism (PE) is a common and potentially life-threatening disorder. Patients with PE often have nonspecific symptoms, and the diagnosis is often delayed.


OBJECTIVE
The aim of our study was to investigate the role of signal peptide-complement C1r/C1s, Uegf, and Bmp1-epidermal growth factor domain-containing protein 1 (SCUBE1) used in the diagnosis of PE.


METHODS
The study was designed prospectively. A total of 57 patients who were admitted to emergency service with clinically suspected PE were included in the study. The patients diagnosed with PE were defined as PE group (n= 32), and the patients with undetectable embolism on computerized tomographic pulmonary angiography were defined as non-PE group (n= 25). Twenty-five age- and sex-matched healthy cases were chosen for the study. Routine biochemical analysis, complete blood count, D-dimer, SCUBE1, and arterial blood gas analysis were performed early after admission.


RESULTS
Mean SCUBE1 levels were higher in the PE group (0.90 ng/mL) than in the non-PE (0.38 ng/mL) and control groups (0.47 ng/mL) (P< 0.01). A cutoff point of 0.49 ng/mL for SCUBE1 indicated 100% sensitivity and 64% specificity in patients with PE. Mean D-dimer levels were not different between PE and non-PE groups (P= 0.591). A multivariable logistic regression analysis (with dichotomous PE groups as the response variable; age, gender, chest pain, syncope, diabetes mellitus, chronic obstructive pulmonary disease, hypertension, D-dimer, neutrophil-lymphocytes ratio, and SCUBE1 variables as predictors) showed that the significant and independent predictors of PE diagnosis were SCUBE1 and chest pain.


CONCLUSIONS
This study suggests that serum SCUBE1 measurement might be used as a diagnostic biomarker in PE.
