Studies of the metabolic activity of leukocytes from patients with a genetic abnormality of phagocytic function

Abstract

Polymorphonuclear leukocytes from patients with chronic granulomatous disease respond to the phagocytosis of latex particles with normal increments in glucose consumption, lactate production, Krebs' cycle activity, and lipid turnover. The leukocytes of these patients fail to show normal increments in respiration, direct oxidation of glucose, and hydrogen peroxide formation during particle uptake. It appears that the stimulation of respiration with the formation of hydrogen peroxide and stimulation of the direct oxidative pathway of glucose metabolism are closely linked to degranulation and intracellular killing of bacteria by polymorphonuclear leukocytes.
