Gram-negative sepsis treated with neutrophils collected exclusively by intermittent flow centrifugation leukapheresis

The effectiveness of neutrophils prepared for transfusion by intermittent flow centrifugation leukapheresis (IFCL) as treatment for serious bacterial infections in neutropenic patients has not been documented in the literature. Their value, in fact, has been questioned. We report that IFCL neutrophils are similar to cells prepared by other techniques in the ability to support neutropenic patients with culture-proven, gram-negative sepsis unresponsive to antibiotics.
