Immune potential in human uraemia. 2. Changes after regular haemodialysis therapy

Parameters of both humoral and cellular immune potential were measured in a group of patients with severe renal failure before and after three months' regular haemodialysis therapy. Evidence is presented of improvement in cellular immune potential and of a tendency of the response of lymphocytes to PHA to return to normal. No improvement in humoral responsiveness was demonstrable, and it is suggested that uraemic patients on regular haemodialysis may have an impaired capacity to establish new immunological memory.
