The incidence and risk factors for hospitalizations for bacterial septicemia, a serious cause of morbidity and mortality in end stage renal disease (ESRD), have been studied separately for patients on chronic dialysis and after renal transplantation, but have not been compared directly. Using data from the USRDS, we studied 11,369 patients with ESRD due to diabetes enrolled on the renal and renal-pancreas transplant waiting list from 1 July 1994-30 June 1997. Cox non-proportional hazards regression models were used to calculate adjusted, time-dependent hazard ratios (HR) for time to hospitalization for bacterial septicemia (ICD9 Code 038.x). In Cox Regression analysis, renal transplantation was independently associated with a shorter time to bacterial septicemia (HR 1.22, 95% confidence interval, 1.05-1.40). In addition, renal transplantation was associated with a higher rate of sepsis due to gram-negative organisms (HR 3.32, 95% CI 2.614.23) and urinary tract infection (10.43, 95% CI 6.72-16.17) compared with patients still on the renal transplant waiting list. The relative risk of sepsis increased with time after renal transplantation. Renal transplantation was associated with a significantly higher risk and different spectrum of bacterial septicemia than maintenance dialysis, and the risk of sepsis did not decrease over time.
细菌性败血症是终末期肾病(ESRD)发病和死亡的一个严重原因,针对接受慢性透析的患者和肾移植后的患者,已分别对其住院率及危险因素进行了研究,但尚未进行直接比较。利用美国肾脏数据系统(USRDS)的数据,我们研究了1994年7月1日至1997年6月30日期间登记在肾脏和肾胰腺移植等待名单上的11369例因糖尿病导致ESRD的患者。采用Cox非比例风险回归模型计算细菌性败血症(国际疾病分类第九版代码038.x)住院时间的校正时依风险比(HR)。在Cox回归分析中,肾移植与细菌性败血症发生时间较短独立相关(HR 1.22,95%置信区间为1.05 - 1.40)。此外,与仍在肾移植等待名单上的患者相比,肾移植患者革兰氏阴性菌引起的败血症发生率更高(HR 3.32,95% CI 2.61 - 4.23),尿路感染发生率也更高(HR 10.43,95% CI 6.72 - 16.17)。肾移植后败血症的相对风险随时间增加。与维持性透析相比,肾移植与细菌性败血症的风险显著更高且谱系不同,并且败血症风险不会随时间降低。
