Familial neutrophil chemotaxis defect, recurrent bacterial infections, mucocutaneous candidiasis, and hyperimmunoglobulinemia E

Abstract

A 20-year old women and her infant daughter had recurrent bacterial infections and chronic mucocutaneous candidiasis and were found to have extreme hyperimmunoglobulinemia E, defective neutrophil chemotaxis, and diminished lymphocyte responses to Candida antigen. Studies of members of the mother's family showed mild increases of IgE and mildly depressed chemotactic activity of neutrophils in a brother, the father, and the paternal grandfather. The recurrent bacterial infections in these two patients can be explained by the defective neutrophil chemotaxis. It is not known whether the mucocutaneous candidiasis is related to the neutrophil chemotaxis with the lymphocyte defect being secondary to the Candida infection or, alternatively, the Candida infection being secondary to the lymphocyte defect. Furthermore, the family data suggest a familial pattern of hyperimmunoglobulinemia E and defective neutrophil motility.
