Analysis of risk factors for pulmonary infection in elderly kidney transplant recipients / 中华器官移植杂志

ABSTRACT

Objective:To explore the risk factors of pulmonary infection in elderly (aged 60+ years) kidney transplant recipients.Methods:The clinical data were retrospectively analyzed for 119 elderly kidney transplant recipients from January 2010 to January 2019 . According to whether or not pulmonary infection occurred after renal transplantation, the recipients were divided into infected group (n=40) and non-infected group (n=79). Clinical data was analyzed for two groups. The relevant risk factors of gender, age, donor type, body mass index, history of smoking, preoperative dialytic time, preoperative dialysis, immune induction, immune maintenance, presence or absence of delayed graft function, leucopenia, serum creatinine before infection, venous hormone shock therapy or not, diabetic history before or after surgery, history of coronary heart disease, history of hepatitis B virus, prophylactic dosing of compound sulfamethoxazole, prophylactic valganciclovir or ganciclovir, were examined by univariate analysis and multivariate logistic regression analysis.Results:The incidence of pulmonary infection in elderly kidney transplant recipients was 33.6% (40/119). In infected group, 15 patients died of severe pulmonary infection with a mortality rate of 37.5%(15/40). History of smoking (OR=10.58, 95%CI 1.98-56.40, P=0.006), venous hormone shock therapy (OR=25.06, 95%CI 4.25-147.71, P<0.001) and preoperative dialytic time (OR=1.032, 95%CI 1.003-1.062, P=0.033) were the risk factors for pulmonary infection in elderly kidney transplant recipients. Conclusions:The incidence and mortality of lung infection are higher in elderly kidney transplant recipients. Smoking history, venous hormone shock therapy and long preoperative dialytic are associated with pulmonary infection in elderly kidney transplant recipients.
