Effect of melatonin on human nighttime endotoxaemia: randomized, double-blinded, cross-over study.
Endotoxaemia is widely used as an experimental model to study sepsis under controlled conditions. Nighttime endotoxaemia induces a more pronounced inflammatory stress response compared to daytime. Previously, we have shown that melatonin has antioxidative and anti-inflammatory effects in inflammatory response to daytime endotoxaemia. Herein, we examined the effect of melatonin in response to human nighttime endotoxaemia. ⋯ Melatonin has no beneficial effect on inflammation and oxidative damage induced by nighttime endotoxaemia in contrast to daytime endotoxaemia.
