Abstrakt: Sepsis is a critical illness with high morbidity and mortality. Anaerobic glycolysis plays an important role in the pathogenesis of sepsis. Pyruvate dehydrogenase complex (PDHC) serves as a key regulator during sepsis. With PDHC dephosphorylation and deacetylation, PDHC activity is upregulated, allowing pyruvate translocate to mitochondria in aerobic condition, preceding the production of acetyl-CoA to accelerate aerobic oxidation. Activation of PDHC improves the prognosis of sepsis through regulating the balance of lactate, release of inflammatory factors and energy metabolism. A variety of remedies can improve the prognosis of patients with sepsis by up-regulating the activity of PDHC, including dichloroacetate (DCA), vitamin B1, milrinone, tumor necrosis factor binding protein, and ciprofloxacin.This article reviews the role and the regulatory mechanism of PDHC and signal pathway in the sepsis metabolism, in order to innovate treatment for sepsis and multiple organ dysfunction.
