ABSTRACT Patients with ICS have an increased frequency of sinusitis and respiratory infections. Abnormal ciliary movement likely contributes to these frequent infections. In addition,

abnormal neutrophil function has been reported previously for some patients with ICS. We have studied neutrophil function in ICS patients with the three known ultrastructural abnormalities

of cilia. Fifteen patients were examined. Their mean age was 12.1 years. Neutrophil functions included; migration assessed under agarose and in Boyden chambers, phagocytosis and killing of

Staphylococcus aureus 502A, and the metabolic activity of cells at rest and during phagocytosis as assessed by hexose monophosphate pathway activity, hydrogen peroxide production,

tetrazolium dye reduction and lysosomal degranulation. When tested, the patients were not on antibiotics. They were afebrile and free of acute infection. Normal neutrophils were studied in

parallel. Five patients with respiratory infections but normal cilia were also examined. No ICS patient demonstrated a significant abnormality in neutrophil migration. Phagocytosis and

killing of S. aureus was normal. There was no evidence of abnormal metabolism by cells at rest or during phagocytosis. Two patients with normal cilia had a transient decrease in neutrophil

migration during a respiratory infection. Our findings suggest that abnormal neutrophil function does not predispose, in a major way, to respiratory infection in patients with ICS. ARTICLE
