Abstract

Systemic inflammatory reaction – due to severe response to toxins of infection associated with immune inhibition – leads to multi-organ dysfunctions and high mortality. Ultraviolet (UV) blood is used for its therapeutic effects when moving across the cells. This study aims to evaluate the impact of UV-c Haematogenous Oxidation Therapy (HOT) in Lipopolysaccharide (LPS)-induced endotoxemia of rabbit model. A total of 40 rabbits randomly divided into four groups, including normal control (NC). LPS and LPS+UV-c HOT groups received 0.1 mg/kg LPS toxin of E. coli, UV-c HOT and LPS+UV-c HOT groups subjected to UV-c HOT treatments once weekly for five times. Blood collected, perfused with oxygen, UV-c directly irradiated into blood, and then auto-transfused. Rabbits were sacrificed after five weeks; blood and serum were collected for analysis. The survival rate, liver, kidney, lipid profile, and blood ions were assessed in treated rabbits. Mortality was 40% in the LPS group, while other groups showed no death. UV-c HOT enhanced critical pH, base deficit, blood gases, hypomagnesemia, hyperlactatemia, and concurrent acidosis. Besides, TNF-α, nitrite, and nitrate were suppressed in response to UV-c HOT. Moreover, UV-c HOT reduced liver and kidney enzymes, improved lipid metabolism, and ameliorated electrolytes homeostasis. Despite that, UV-c HOT performance in ICU for human and animal endotoxemic or septic patients should be evaluated and considered.
