Abstrakt: We reviewed the results of routine microbiological assays of 3078 infused hematopoietic progenitor cell (HPC) products for autologous and allogeneic transplantation between January 2001 and December 2005. Thirty-seven (1.2%) contaminated products were found. All patients receiving contaminated infusions received empirical antibiotic prophylaxis according to the assay result. None of these patients developed a positive blood culture with the same agent, developed infections that could be attributable to the contaminated product or experienced any clinical sequelae. Coagulase-negative Staphylococcus was found in 32 (86.5%) products. Admission lengths and time to engraftment were within the expected time frame for autologous and allogeneic transplants. Microbial contamination of HPC products occurs at a low frequency; prophylactic use of antibiotics based on the microbiological assay appears to be effective in preventing clinical complications.
