[Vasoactive factors in chronic glomerulonephritis].

Background: The kidney damage in chronic glomerulonephritis develops not only as a result of causal immunopathological evens, but also due to chronic adaptation changes. The study was aimed at identification of active agents, which can serve as markers of proceeding adaptation changes and to determine, if these changes may be determined in patients undergoing the stage of remission of chronic glomerulonephritis.

Methods And Results: The authors determined renin activity, concentration of atrium natriuretic peptide and endothelin in plasma and elimination of some prostanoids in urine in 33 patients with chronic stabilized glomerulonephritis with normal glomerular filtration and with normal blood pressure and in 21 healthy subjects.

[Microalbuminuria in patients with glomerulonephritis in remission].

The authors focused their attention on residual changes in patients with glomerulonephritis who have a zero or only "physiological" proteinuria (under 0.15 g/24 hours), normal or slightly elevated s-creatinine and who do not suffer from hypertension. In these patients microalbuminuria in urine per 24 hours was assessed.

[Present possibilities of treatment of primary chronic glomerulonephritis].

The authors evaluate in a retrospective study the effect of prednisone, cyclophosphamide, small doses of acetylsalicylic acid, conventional antihypertensive drugs and ACE inhibitors on the course of primary chronic proliferative types of glomerulonephritis. The group comprised 44 patients, incl. 16 with normal blood pressure and 28 with hypertension.

[Treatment of macroscopic hematuria complicating renal biopsy by embolization of a branch of the renal artery].

The authors describe a case of recurrent macroscopic haematuria which developed after renal biopsy in a young patient with IgA dominant focal and segmental mesangioproliferative glomerulonephritis. As conservative treatment was not successful, renal angiography was performed which revealed a false aneurysm of the segmental branch of the renal artery at the site of the assumed puncture. After selective embolization with gelaspon granules macroscopic haematuria receded quickly.
