PHAGOCYTIC CELL DEFICIENCIES
Phagocytes include white blood cells (neutrophils and macrophages) that engulf and kill antibody coated foreign invaders. Phagocytes can be defective either in their ability to kill pathogens or in their ability to move to the site of an infection. In either case, the defect results in increased infections.
The most severe form of phagocytic cell deficiency is:
Chronic Granulomatous Disease
Chronic Granulamatous Disease (CGD) is an inherited deficiency of molecules needed by neutrophils to kill certain infectious organisms. People with chronic granulomatous disease develop frequent and severe infections of the skin, lungs and bones and develop localised, swollen collections of inflamed tissue called granulomas.
Neutropenia is characterized by an abnormally low number of neutrophils.
