The immune response in 55 uremic patients maintained on hemodialysis was measured with PPD, PHA skin test and PHA induced blastoid transformation of peripheral lymphocytes in in vitro system. Positive rate of PPD skin test was 62% in uremic patients, which was low in general Japanese adults. Mean diameter of erythema of skin reaction at 48 hours after the intradermal injection of 5 µg PHA was 21.1±11.8 (mean±SD) mm in uremic patients and 36.6±17.3 mm in normal control subjects. The difference between them was significant at P<0.001 Blastoid transformation of lymphocytes was determined with quantitation of tritium thymidine incorporation (cpm) and the ratio of blastogenasis was revealed as stimulation index (SI). S1 was 32.1±25.5 in uremic patients and 50.2±27.2 in control subjects. The difference between them was significant at P<O.OI. S1 was low in the uremic patients with high serum creatinine level. On this investigation, cellular immune response was reduced in uremic patients and lymphocyte transformation using whole blood culture was useful method for evaluation of cellular immune competence in severe anemic patients.
