Unlabelled:
Mesangioproliferative glomerulonephritis (GNpm) is one of the most frequent histopathological forms in patients with proteinuria and erythrocyturia. The aim of this study was to assess the rate of deterioration of renal function in 39 patients with mesangioproliferative glomerulonephritis. All patients (25 M and 14 F, age from 19 do 55 year) were diagnosed in the Department of Nephrology Silesian University School of Medicine in Katowice two times: before and at least 12 month after renal biopsy respectively. 21 patients with mesangioproliferative glomerulonephritis was oligosymptomatic. In 6 patients the leading sign of GNpm was moderate arterial hypertension while in the other 22 nephrotic syndrome. 17 patients with mesangioproliferative glomerulonephritis received immunosuppressive medication while in the other 22 patients these drugs were not used. Deterioration of renal function was assessed using a progression index (PI) which is calculated by dividing delta of serum creatinine (mumol/l) by the observation period (months). Deterioration of renal function was faster in nephrotic patients (PI = 0.27 +/- 0.11 mumol creat./month) and in patients with the hypertensive form of mesangioproliferative glomerulonephritis (PI = 0.69 +/- 0.29 umol creat./month) than in patients with oligosymptomatic mesangioproliferative glomerulonephritis (PI = 0.06 +/- 0.04 mumol creat./month). Significantly slower deterioration of renal function was noticed in patients treated with immunosuppressive drugs than medicated only symptomatically (PI = 0.05 +/- 0.007 mumol creat./month vs 0.70 +/- 0.06 mumol creat./month).
Conclusions:
1) Presence of hypertension and of a nephrotic syndrome does influence adversely the progression of mesangioproliferative glomerulonephritis.(ABSTRACT TRUNCATED AT 250 WORDS)
Insights
Mesangioproliferative glomerulonephritis (GNpm) progression is faster with hypertension or nephrotic syndrome. Immunosuppressive treatment significantly slowed renal function decline in these patients.
Area of Science:
- Nephrology
- Immunology
Background:
- Mesangioproliferative glomerulonephritis (GNpm) is a common cause of proteinuria and erythrocyturia.
- Understanding GNpm progression is crucial for effective patient management.
Purpose of the Study:
- To assess the rate of renal function deterioration in patients with GNpm.
- To identify factors influencing GNpm progression.
Main Methods:
- Retrospective analysis of 39 GNpm patients.
- Renal function assessed via serum creatinine and a progression index (PI).
- Comparison of PI based on clinical presentation and treatment.
Main Results:
- Faster renal function decline observed in nephrotic (PI = 0.27) and hypertensive (PI = 0.69) GNpm patients compared to oligosymptomatic (PI = 0.06).
- Significantly slower deterioration in patients receiving immunosuppressive drugs (PI = 0.05) versus symptomatic treatment (PI = 0.70).
Conclusions:
- Hypertension and nephrotic syndrome adversely impact GNpm progression.
- Immunosuppressive therapy demonstrates a renoprotective effect in GNpm.
