Kidney transplants from infected donors: our experience

Organ procurement from infected donors may transmit a disease to the recipient that could cause a graft loss and/or recipient morbidity. Retrospectively, all kidney transplants from infected donors at our center in the last 4 years were reviewed. A donor was considered infected in the presence of at least one positive culture before procurement. From January 1999 to 2003, 23 of 160 donors (14.5%) were infected: in 10 donors a positive blood culture; in 3, a urine culture; and in 13, a bronchial culture. In a further 12 (7%) donors, only the preservation solution was contaminated. Organisms isolated were: Staphylococcus coagulase.neg. (n = 7); Staphylococcus epidermidis (n = 3); Staphylococcus aureus (n = 6); Klebsiella pneumoniae (n = 3); Pseudomonas aeruginosa (n = 4); Acinetobacter (n = 1); Candida albicans (n = 13); Aspergillus (n = 1); and Escherichia coli (n = 1). All except 2 kidneys were transplanted with positivity in all cultures. All recipients received general, nonspecific, antibacterial and antifungal prophylaxis until the antibiotic and antifungal spectrum was ready. Patient and graft survival rates at 6 months were 94% and 93%, respectively. Two deaths occurred due to bacterial arteritis (P aeruginosa), and 2 acute graft losses due to fungal arteritis. Kidneys from infected donors seem suitable for transplants. Only grafts infected by vasculotropic agents (S aureus, P aeruginosa, and C albicans) should be discarded.
