title: Subpopulations of T and B lymphocytes in peripheral blood and lymphocytes reactivity to non-specific mitogens (PHA, Con A, PWM) in in vitro cultures in patients suffering from in vitro cultures in patients suffering from glomerulonephritis.
abstract: Studies were performed on 79 subjects, out of which 32 belonged to the control group and 47 suffered from glomerulonephritis. The number of T and B lymphocytes in peripheral blood was determined using the technique of E, EA and EAC-rosette tests. Also, the lymphocyte blast response to non-specific mitogens (PHA, Con A, PWM) was established in vitro. Patients suffering from acute proliferative glomerulonephritis, as compared to the control group, displayed a statistically significant increase of lymphocytes with the receptor for complement (EAC-rosettes). Their reactivity to all three mitogens did not differ from the values obtained in the control group. In patients suffering from chronic glomerulonephritis (proliferative, membranous-proliferative, membranous), shiftings in the contents of the peripheral blood lymphocytes pools were of opposite directions, i.e., statistically significant in comparison with the control group. Also an increase in the absolute number of T lymphocytes (E-rosettes) was observed. Generally speaking, the values of blast transformations after mitogen stimulations were smaller in patients suffering from chronic than in those suffering from acute glomerulonephritis. In 1/3 of them, the decrease of blast response to one of the three mitogens was detected. The decrease exceeded the lower limit of values of healthy subjects, and most often, it was connected with Con A stimulation.
