PLA2 enzymes damage endothelial cell membranes directly and promote the release of inflammatory mediators (leukotrienes, prostaglandins). They also inhibit platelet aggregation through the hydrolysis of platelet membrane phospholipids, exacerbating the bleeding diathesis.

SVMPs degrade the basement membrane of capillary endothelial cells. By cleaving type IV collagen, laminin, and fibronectin, they increase vascular permeability, leading to local edema, blistering, and systemic capillary leak syndrome. This directly causes petechiae, ecchymosis, and spontaneous systemic hemorrhage. PLA2 enzymes damage endothelial cell membranes directly and
