This study was conducted to assess the levels of inflammatory factors and angiogenic factors in patients with severe hemophilia A and evaluate their diagnostic values for acute joint bleeding. This study included a total of 144 patients with severe hemophilia A. Of them, 66 had acute joint bleeding. Ninety healthy volunteers were recruited as control. The levels of leukocytes, monocytes, platelets, hemoglobin, phagocyte migration inhibitory factor (MIF), plasminogen, fibrin/fibrinogen degradation products, d-dimer, and α2 antifibrinolytic enzyme were measured using hematology analyzer. Thrombomodulin, endostatin, intercellular adhesion molecule 1, and vascular endothelial growth factor (VEGF) were assessed using enzyme-linked immunosorbent assay. Logistic regression analysis was performed to analyze the factors affecting acute joint bleeding. Compared with healthy volunteers, the levels of leukocytes, C-reactive protein (CRP), MIF, and VEGF were significantly ( < .05) elevated in the patients with severe hemophilia A and were significantly higher in patients with joint bleeding than in patients with nonbleeding ( < .05). Multivariate analysis showed that CRP and VEGF were independent risk factors for acute joint bleeding ( < .05). The area under the curve, sensitivity, and specificity of CRP for the diagnosis of acute joint bleeding were 0.829, 88.43%, and 67.87%, respectively, and those of VEGF were 0.758, 82.8%, and 68.3%, respectively. The levels of inflammatory factors and angiogenesis factors are elevated in patients with severe hemophilia A and both CRP and VEGF are closely related to acute joint bleeding and may be used as potential biomarkers for predicting acute joint bleeding in patients with severe hemophilia A.
