[Progress of nicotinamide in preventing infection and sepsis]

Sepsis is a common clinical critical disease, which is one of the main causes of septic shock and multiple organ dysfunction syndrome (MODS). Since traditional clinical interventions are simple and limited, the mortality of sepsis remains high and is also one of the main causes of death of intensive care unit (ICU) patients. Nicotinamide has a wide range of cytoprotective effects. A large number of studies have shown that nicotinamide can play an important role in infection and sepsis by repairing mitochondrial function to restore adenosine triphosphate (ATP) level, inhibiting poly (ADP-ribose) polymerase (PARP) activation, inhibiting proinflammatory mediators and antioxidant damage. This article reviews the pathogenesis of sepsis and the role of nicotinamide in sepsis treatment, aiming to provide references for exploring new therapeutic directions and effective therapeutic measures for sepsis.
