[IgA nephropathy].

A great interest in IgA nephropathy was demonstrated in the last few years. Unfortunately, a complete picture of this chronic disease should not yet been made. The article deals with 7 patients with IgA nephropathy treated in our Institute. The following characteristics were examined during a long period of time (1-17 years): clinical picture, course of the disease, clinical and morphologic correlations. The disease is characterised by micro-and macro-haematuria. In 6 patients a moderate proteinuria and slow progression of the disease were noted. Hypertension, massive proteinuria and azothemia in IgA nephropathy suggested a bad prognosis of the disease. This was confirmed in one patient who developed terminal renal insufficiency within 4 months. The pathological finding by optic microscope revealed a wide spectrum of changes. The role of immunofluorescent microscopy is crucial in the diagnosis of this disease.
