Significance of T and B lymphocytes in different chronic internal diseases with immune processes

The T and B lymphocytes were determined by the rosette test in the peripheral blood of 100 patients with internal chronic diseases with immune processes such as: chronic hepatitis, systemic lupus erythematosus, myasthenia gravis, chronic lymphocytic leukemia and lymphosarcoma. The values obtained were compared with those in 10 controls. The mean per cent values of the T lymphocytes in the controls were 33 (29-38%) and of the B lymphocytes 25.2 (16-43%). In the patients investigated the values varied, namely: in chronic hepatitis and systemic lupus erythematosus the T lymphocytes were generally low while the B lymphocytes were moderately high. In myasthenia gravis both T and B lymphocytes were below the control values. In chronic lymphocytic leukemias and lymphosarcomas the per cent values of the T lymphocytes were generally low while those of the B lymphocytes were high. The significance of these results for the immunologic implications of the lymphocyte populations is discussed and an attempt is made to correlate these data with the nucleologram variations.
