[Results of a multicenter study of the early detection of glomerulonephritis. 1]

In the framework of a multicentric retrospective study between selected clinics of the Republic Austria and the GDR anamnestic, clinical and paraclinical data were investigated in their valency for the early recognition of glomerulonephritis. Data of 583 patients were evaluated. Hereby it was shown that independent of the size of excretion and the reproducibility the findings "proteinuria" are of particular significance for the early recognition. The serological investigations usually performed within the diagnostic of glomerulonephritis proved as insignificant for the early recognition. Since the establishing of an exact diagnosis is up to now possible only with the help of invasive methods, a call on research is made to develop reliable, non-invasive diagnostic methods.
