Risk factors for hospitalization for bacterial or viral infection in renal transplant recipients--an analysis of USRDS data.
We previously showed that children are more likely to develop viral infections post-kidney transplant while adults are more likely to develop bacterial infections. In this study we determined the overall risk factors for hospitalization with either a bacterial (HBI) or a viral infection (HVI). We analyzed data from 28 924 United States Renal Data System (USRDS) Medicare primary renal transplant recipients from January 1996 to July 2000, for adjusted hazard ratio (AHR) for HBI or HVI in the first 3 years posttransplant. For HVI, significantly higher AHR was seen with (a) recipient age <18 years (AHR 1.57, 95% CI = 1.02, 2.42), (b) donor CMV positive (AHR 1.72, 95% CI = 1.34, 2.19). For HBI, significantly higher AHR was seen with (i) delayed graft function (AHR 1.28, 95% CI = 1.076, 1.518), (ii) primary renal diagnosis chronic pyelonephritis (AHR 1.71, 95% CI = 1.18, 2.49); (iii) associated pretransplant diabetes (AHR 1.80, 95% CI = 1.53, 2.12); (iv) female gender AHR 1.63, 95% CI = 1.41, 1.88). Lower AHR for HVI was seen in CMV-positive recipients and for HBI with more recent year of transplant. Other covariates did not impact significantly in either HVI or HBI.
