“…23 It is well recognized that vancomycin infusions, often augmented by other ubiquitous medications of hospitalization, such as opioids, can induce histamine release; histamine impacts vascular permeability and tissue edema. 25,26 It is possible that vancomycin exacerbated renal dysfunction, leading to increased accumulation or reduced clearance of gadolinium in tissue or, alternatively, it impaired other homeostatic processes or induced further endothelial dysfunction. Sepsis and infection (viral, bacterial, and parasitic) can alter expression of cytokines that impact the endothelium, such as endothelin-1 and vascular endothelial growth factor.…”
