Objective:
We aimed at investigating the expression level of vascular endothelial growth factor-A (VEGF-A) in patients with primary Sjögren's Syndrome (pSS) and evaluating the relationship between serum VEGF-A and the laboratory indicators that are associated with it in pSS.
Methods:
The VEGF-A levels were measured by ELISA in a total of 88 participants, including 58 patients with pSS and 30 healthy people. The VEGF-A levels between two groups were analyzed.
Results:
The serum levels of VEGF-A in pSS and control groups were 175.50 (112.00,296.50) pg/mL and 181.50 (155.25,288.50) pg/mL, without statistically significant difference. The associations were found between serum levels of VEGF-A with C reactive protein (CRP) (r=0.265, P<0.05), white blood cells (WBC) (r=0.302, P<0.05), neutrophils (NEUT) (r=0.349, P<0.05), platelets(PLT) (r=0.276, P<0.05), complement 3 (C3) (r=0.477, P<0.05), complement 4 (C4) (r=0.387, P<0.05) and CA19-9 (r=0.392, P<0.05). Among these laboratory indicators, VEGF-A was correlated with platelets and complement 4 in patients with pSS.
Conclusions:
In patients with pSS, the levels of VEGF-A were independently influenced by the levels of platelet and complement 4, which indicated the intermodulation between the growth factor and immune system in the autoimmune disease.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
