Early enteral nutrition (EEN) can modulate the inflammatory response, improve immune dysfunction, and prevent enterogenic infection in critically ill patients;however, the precise mechanisms remain unclear. Considering the important roles of Th17 and Treg lymphocytes in the development of inflammatory and infectious diseases, we hypothesized that EEN could improve the immune dysfunction in sepsis by maintaining a balanced Th17/Treg cell ratio and by regulating the IL- 23/IL-17 axis. AIM To investigate the effects of EEN on the Th17/Treg cell ratios and the IL-23/IL-17 axis in septic patients. METHODS In this prospective clinical trial, patients were randomly divided into an EEN or delayed enteral nutrition (DEN) group. Enteral feeding was started within 48 h in the EEN group, whereas enteral feeding was started on the 4th day in the DEN group. The Th17 and Treg cell percentages and the interleukin levels were tested on days 1, 3, and 7 after admission. The clinical severity and outcome variables were also recorded. RESULTS Fifty-three patients were enrolled in this trial from October 2017 to June 2018. The Th17 cell percentages, Th17/Treg cell ratios, IL-17, IL-23, and IL-6 levels of the EEN group were lower than those of the DEN group on the 7th day after admission (P < 0.05). The duration of mechanical ventilation and of the intensive care unit stay of the EEN group were shorter than those of the DEN group (P <0.05). However, no difference in the 28-d mortality was found between the two groups (P = 0.728). CONCLUSION EEN could regulate the imbalance of Th17/Treg cell ratios and suppress the IL- 23/IL-17 axis during sepsis. Moreover, EEN could reduce the clinical severity of sepsis but did not reduce the 28-d mortality of septic patients.展开更多
