Hypertension and renal insufficiency in children with chronic glomerulonephritis
Insights
Hypertension significantly increases the risk of renal insufficiency in children with chronic glomerulonephritis, particularly those with proliferative glomerulonephritis (PGN) and membrano-proliferative glomerulonephritis (MPGN). Early detection and management of hypertension are crucial for preserving kidney function.
Area of Science:
- Nephrology
- Pediatric Nephrology
- Clinical Research
Background:
- Chronic glomerulonephritis affects children, potentially leading to kidney damage.
- Hypertension is a known complication and risk factor in kidney diseases.
Purpose of the Study:
- To investigate the correlation between hypertension and kidney function decline in pediatric chronic glomerulonephritis.
- To identify specific histological types of glomerulonephritis associated with increased hypertension risk and functional deterioration.
Main Methods:
- A cohort of 95 children with chronic glomerulonephritis was analyzed.
- Patients were categorized by histological findings: minor glomerular abnormalities (MGA), proliferative glomerulonephritis (PGN), membrano-proliferative glomerulonephritis (MPGN), membranous glomerulonephritis (MGN), and focal segmental glomerulosclerosis (FSGS).
- Blood pressure and renal function (renal insufficiency) were assessed and compared between hypertensive and normotensive groups within each histology category.
Main Results:
- Fourteen out of 95 children were hypertensive. Hypertension was absent in MGA and MGN groups.
- No significant difference in hypertension prevalence was observed among PGN, MPGN, and FSGS groups.
- Overall renal insufficiency incidence was significantly higher in hypertensive (50.0%) versus normotensive (4.9%) children (p < 0.0001).
- Renal insufficiency incidence was significantly higher in hypertensive children with PGN (p < 0.01) and MPGN (p < 0.05) compared to their normotensive counterparts.
Conclusions:
- Hypertension is significantly correlated with functional deterioration in children with chronic glomerulonephritis.
- Children with PGN and MPGN who develop hypertension face a higher risk of progressing to renal insufficiency.
- These findings underscore the importance of monitoring and managing hypertension in pediatric chronic glomerulonephritis to prevent adverse kidney outcomes.
Abstract:
Ninety five children with chronic glomerulonephritis were studied to analyze the correlation between hypertension and functional deterioration in each of the following histology groups; minor glomerular abnormalities (MGA), proliferative glomerulonephritis (PGN), membrano-proliferative glomerulonephritis (MPGN), membranous glomerulonephritis (MGN) and focal segmental glomerulosclerosis (FSGS). Among the 95 patients, 14 patients revealed to be hypertensive. All patients with MGA and MGN revealed normal blood pressure. There were no statistically significant differences in the prevalence of hypertension in patients with PGN, MPGN and FSGS. The overall incidence of renal insufficiency was significantly higher in the hypertensives (50.0%) than in the normotensives (4.9% p less than 0.0001). The incidences of renal insufficiency were significantly higher in the hypertensives than in the normotensives in patients with PGN (P less than 0.01) and MPGN (P less than 0.05). These data suggest that there is a significant correlation between functional deterioration and hypertension, and that the hypertensive patients with PGN and MPGN are at risk for progression to renal insufficiency.
