Infection of the uterus is accompanied by systemic fluctuations of inflammatory cytokines like tumor necrosis factor (TNF), interleukin (IL)-1, IL-6, and acute phase proteins (APP) such as lipopolysaccharide-binding protein (LBP), serum amyloid A (SAA), and haptoglobin (Hp) [9–11]. Here, LBP is linked to infection.
