Correction of Leukocyte Function in Chediak-Higashi Syndrome by Ascorbate

Abstract
Because ascorbate potentiates chemotaxis of normal leukocytes, we examined the effect of ascorbate on polymorphonuclear leukocytes from a patient with the Chediak-Higashi syndrome. Chemotactic migration was 104±16 leukocytes per 10 fields (mean±S.D.) initially and 258±44 (P7 polymorphonuclear leukocytes to 5.9, as compared to a control value of 3.1 ±1.4. The association of elevated cAMP and impaired function in the polymorphonuclear leukocytes of patients with the Chediak-Higashi syndrome may be related to abnormal microtubular assembly.
