Defective polymorphonuclear leukocyte chemotaxis and bactericidal capacity in a boy with recurrent pyogenic infections

Abstract

A 13-year-old boy with a history of recurrent pyogenic infections had abnormalities of polymorphonuclear leukocyte (PMN) function which probably accounted for his susceptibility to infection. PMN phagocytosis and nitroblue tetrazolium dye reduction were normal but glucose 14C oxidation was abnormally increased in resting cells. The patient's PMNs possessed decreased bactericidal activity against Staphylococcus aureus and Escherichia coli. Also documented were decreased PMN chemotactic activity and leukocyte accumulation in Rebuck skin windows. PMN random motility, PMN bone marrow reserve, PMN kinetics, lymphocyte blastogenesis, and delayed cutaneous hypersensitivity were normal. This patients represents another of the growing number of distinct granulocytopathies currently being recognized which may result in increased susceptibility to infection.

Bacterial Pneumonia

Bacterial pneumonia is a prevalent and costly infection that is a significant cause of morbidity and mortality in patients of all ages. Here is the latest research.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
