Boiden camera tests, chemiluminescence of urinary supernatant, passive
hemagglutination tests were used in measuring chemotactic properties
of the urine, intensity of free-radical processes, fibronectin urine c
oncentrations, respectively, in 31 glomerulonephritis (GN) patients. T
he above parameters were closely related to nephritis activity. These
were much lower in patients with nephritis remission, than in subjects
with nephrotic syndrome or exacerbation of latent nephritis. Chemotac
tic activity and intensity of free-radical processes were unrelated to
protein urea which, however, correlated with fibronectin concentratio
ns (r=0.35, p<0.05). The authors discuss the role of the mediators' va
lues in evaluation of local renal inflammation and feasibility of thei
r use as criteria of nephritis activity and prognosis.
