The effect of hemodialysis on neutrophil chemotactic responsiveness.

After several hemodialysis treatments, neutrophil chemotactic responsiveness is commonly depressed. The median chemotactic index of 34 patients was 21, compared with 47 for 21 controls tested simultaneously. The depressed chemotactic responsiveness was not restored to normal when leukocytes were washed and resuspended in normal plasma, neither did plasma from patients with depressed chemotaxis affect control neutrophils.
