Patients with and without adverse reactions on practolol therapy showed altered immune responses. There was cutaneous anergy to Candida albicans and streptokinase/streptodornase antigens and depression of lymphocyte function in vitro. Anticomplementary activity and a wide range of autoantibodies were found in patients who had received practolol.
