Abstract

Abstract: Background: Coronavirus disease 2019 (COVID‐19) is a respiratory disease associated with vascular inflammation and endothelial injury. Objectives: To correlate circulating angiogenic markers vascular endothelial growth factor A (VEGF‐A), placental growth factor (PlGF), and fibroblast growth factor 2 (FGF‐2) to in‐hospital mortality in COVID‐19 adult patients. Methods: Consecutive ambulatory and hospitalized patients with COVID‐19 infection were enrolled. VEGF‐A, PlGF, and FGF‐2 were measured in each patient ≤48 h following admission. Results: The study enrolled 237 patients with suspected COVID‐19: 208 patients had a positive diagnostic for COVID‐19, of whom 23 were mild outpatients and 185 patients hospitalized after admission. Levels of VEGF‐A, PlGF, and FGF‐2 significantly increase with the severity of the disease ( P < .001). Using a logistic regression model, we found a significant association between the increase of FGF‐2 or PlGF and mortality (odds ratio [OR] 1.11, 95% confidence interval [CI; 1.07–1.16], P < .001 for FGF‐2 and OR 1.07 95% CI [1.04–1.10], P < .001 for PlGF) while no association were found for VEGF‐A levels. Receiver operating characteristic curve analysis was performed and we identified PlGF above 30 pg/ml as the best predictor of in‐hospital mortality in COVID‐19 patients. Survival analysis for PlGF confirmed its interest for in‐hospital mortality prediction, by using a Kaplan‐Meier survival curve ( P = .001) and a Cox proportional hazard model adjusted to age, body mass index, D‐dimer, and C‐reactive protein (3.23 95% CI [1.29–8.11], P = .001). Conclusion: Angiogenic factor PlGF is a relevant predictive factor for in‐hospital mortality in COVID‐19 patients. More than a biomarker, we hypothesize that PlGF blocking strategies could be a new interesting therapeutic approach in COVID‐19.
