Background: We hypothesised that nonobese postmenopausal women (NoPoW) and diabetic NoPoW (DNoPoW) may be independently associated with postprandial endotoxemia. Materials and Methods: NoPoW and DNoPoW were evaluated for weight, eating habits, physical activity, body circumferences, fasting plasma glucose level, postprandial plasma glucose level, and insulin level. The lipopolysaccharide (LPS) levels and circulating LPS-binding protein (LBP) were determined in serum at fasting, 1 h, 2 h, 3 h, and 4 h after meal intake and their levels were co-related in 80 NoPoW and 80 DNoPoW. Results: Both DNoPoW group and NoPoW group showed a significant increase (P < 0.05) in LPS levels and circulating LBP in plasma after the meal intake, interestingly the increase was higher in the DNoPoW group. Conclusions: Elevated LPS and circulating LBP were associated significantly with DNoPoW group and NoPoW, especially after a meal intake. These findings suggested a role of LPS and LBP in postprandial systemic inflammation in DNoPoW group. Prospective studies are needed to confirm these results.
