  • Title: Recurrent Pseudomonas infection associated with neutrophil dysfunction.
    Author: Shigeoka AO, Hill HR.
    Journal: Scand J Infect Dis; 1978; 10(4):307-11. PubMed ID: 103188.
    Abstract:
    A 72-year-old male is described with a history of 4 episodes of Pseudomonas aeruginosa sepsis and chronic otitis media caused by pseudomonas species. In vitro testing of the patient's polymorphonuclear leukocytes (PMNs) revealed profoundly abnormal chemotactic responses and defective intracellular killing of Ps. aeruginosa, Staphylococcus aureus and Escherichia coli. Chemiluminescence production by the patient's PMNs in response to opsonized zymosan as well as endotoxin stimulated nitroblue tetrazolium dye reduction were markedly depressed. These data indicate the presence of a profound, apparently acquired, defect in PMN function in an elderly male. Detailed evaluation of adult patients with recurrent infections may reveal similar, apparently acquired defects in PMN function.
