Insights
Age impacts Henoch-Schönlein purpura nephritis (HSPN) outcomes. Adults and children show distinct clinical and pathological features, with severe pathology linked to proteinuria, renal failure, and pain. Renal biopsy is crucial for both groups.
Area of Science:
- Nephrology
- Pediatric Nephrology
- Rheumatology
Background:
- Henoch-Schönlein purpura (HSP) predominantly affects children, but age is a key prognostic factor.
- Kidney involvement in HSP significantly contributes to patient mortality.
- Understanding clinicopathological differences between pediatric and adult HSP is crucial.
Purpose of the Study:
- To investigate the clinicopathological correlations in adult versus pediatric patients with Henoch-Schönlein purpura nephritis (HSPN).
Main Methods:
- Retrospective evaluation of 208 children and 75 adult patients diagnosed with HSPN.
- All participants underwent renal biopsy for detailed pathological assessment.
Main Results:
- Pediatric patients exhibited higher rates of extra-renal symptoms (arthritis, abdominal pain) compared to adults.
- Adult patients showed a higher incidence of renal symptoms like edema and hypertension.
- Pathological findings correlated significantly with clinical presentation, with activity linked to renal failure and chronicity associated with age and proteinuria.
Conclusions:
- Significant clinicopathological disparities exist between pediatric and adult HSPN patients.
- Severe HSPN pathology is associated with massive proteinuria, renal failure, and abdominal pain.
- Renal biopsy is recommended for both pediatric and adult HSPN patients presenting with recurrent hematuria or persistent proteinuria.
Background:
Henoch-Schönlein purpura (HSP) mainly affects children, but age is also thought to be an important prognostic factor. Kidney involvement is a major cause of mortality in HSP patients. The purpose of this study was to analyze the clinicopathological correlations between adults and children.
Methods:
A total of 208 children and 75 adult patients with HSP nephritis (HSPN) were evaluated. All patients underwent a renal biopsy.
Results:
Extra-renal symptoms (arthritis and abdominal pain) were more common in the pediatric patient group than in the adult group (P < 0.05), but renal symptoms (edema and hypertension) were relatively rare (P < 0.05). A significant positive correlation was noted between pathological type and clinical type (P < 0.01). Pathological activity was positively related to renal failure, abdominal pain, microscopic hematuria, hypertension, and proteinuria (P < 0.05). Pathological chronicity was positively associated with age, duration of follow-up since the onset of palpable purpura, renal failure, lower extremity edema, hypertension, and proteinuria (P < 0.05).
Conclusions:
Various clinicopathological differences exist between children and adults with HSPN. Massive proteinuria, renal failure, and abdominal pain usually correlated with severe pathology. Renal biopsy should be performed in both pediatric and adult HSPN patients with repeated hematuria and/or consistent minimal proteinuria.
