Abstract/OtherAbstract:
BACKGROUND: Proteinuria is a common presentation of mesangioproliferative glomerulonephritis (MsPGN). No studies are available on the long-term effect of treatment by renin-angiotensin system (RAS) inhibitors on renal outcome in MsPGN patients. This study prospectively evaluates the effects of RAS inhibitors on renal outcome in patients with low risk MsPGN followed up for 10years using historical patients with similar features at the time of presentation as untreated controls.
METHODS: Endpoints: decrease of basal proteinuria>20% and loss>20% of basal glomerular filtrate rate (GFR) at the end of first year of observation. The patients were re-evaluated bimonthly during the first year and every 6months thereafter.
RESULTS: Twenty-five patients fulfilled the selection criteria. After one year follow-up 19 patients reached the endpoint of proteinuria and no patient reached the endpoint of GFR. No significant change in blood pressure levels (BP) and GFR was registered, by contrast daily proteinuria decreased significantly (p<0.001), falling by 29% at sixth month and 47% at the end of the follow-up. The historical control group consisted of 15 untreated patients seen between 1987 and 1992. The two-way analysis of variance for repeated measures showed greater values of GFR (p<0.001) and lower levels of daily proteinuria (p<0.001) in treated patients as compared to untreated controls.
CONCLUSIONS: This 10-year follow-up study indicates that the early treatment with RAS inhibitors at low doses favourably influences the long-term renal outcome in proteinuric patients with MsPGN. Limitations were the small sample size and lack of randomization.
