Impact of preoperative infection on the outcomes of liver transplant recipients: a national propensity score-matched retrospective cohort study in China.

ABSTRACT:

Background

Impact of preoperative infection on liver transplantation (LT) needs further investigation.

Materials and methods

From January 1, 2015 to December 31, 2022, 24,122 eligible patients receiving LT were enrolled from the China Liver Transplant Registry database. The outcomes of LT were compared after using the propensity score-matched analysis.

Results

Compared to the non-infection group, patients in the infection group were more likely to have postoperative effusion, infection, abdominal bleeding and biliary complications (all P<0.01), and they had shorter 30-day, 90-day survival and overall survival (OS) (all P<0.01). Cox proportional hazards regression analysis revealed that MELD score and cold ischemia time were risk factors for the OS in the infection group (both P<0.05). Besides, compared to the non-pulmonary group, patients in the pulmonary group were more likely to have postoperative effusion and infection (both P<0.0001), and less likely to have postoperative abscess and early allograft dysfunction (both P<0.05). Patients in the non-abdominal group also had a higher proportion of postoperative infection than those in the abdominal group (P<0.05). Furthermore, compared to the number=1 group, patients in the number≥2 group were more prone to postoperative effusion and infection (both P<0.01), and they also had shorter 30-day and 90-day survival (both P<0.05).

Conclusion

Preoperative infection can result in a higher incidence of early postoperative complications and shorter survival in liver transplant recipients. The types and number of infection sites will also influence the prognosis of liver transplant recipients.
