Infectious complications associated with renal transplantation: an analysis of risk factors.
To assess the multiple risk factors reported to be associated with onset of serious bacterial, fungal, viral, and protozoal infections in renal allograft recipients, a retrospective study of all renal transplantations performed at Yale-New Haven Medical Center from the inception of the transplantation program in December, 1967, to December, 1975, was undertaken. Ninety-six renal allograft transplants in 85 patients were available for evaluation during this study period. Renal allograft recipients were evaluated for incidence of infection from time of transplantation until transplant nephrectomy, death, or January 1, 1976. All infections were characterized by type of infection, organism, site, and time of onset post-transplantation. Recipients with infections were also evaluated for their donor type, living-related or cadaveric, age at time of transplantation, granulocytopenia, corticosteroid therapy, and rejection episodes. There were 215 infections, 92 of which were defined as serious, in 78 of the 96 renal allograft recipients. Eighteen renal allograft recipients had no infections. Granulocytopenia, but not rejection, correlated with serious infections at some time in the patient's course. However, no significant temporal relationship between serious infections and episodes of granulocytopenia or rejection could be established. Mortality rate and incidence of serious infection was higher in the group receiving high dose corticosteroid therapy compared with the group receiving lower doses of corticosteroids. The mortality rate in these 85 transplant recipients was 33%. Seventy-four percent of these deaths were directly related to infection (24% of 85 patients).
