Insights
This study analyzed 411 Iranian children with glomerular diseases, finding nephrotic syndrome and renal failure were common. Focal-segmental sclerosis was the most frequent biopsy finding in children with primary nephrotic syndrome.
Area of Science:
- Pediatric Nephrology
- Glomerular Diseases
- Renal Biopsy Analysis
Background:
- Glomerular diseases represent a significant health concern in pediatric populations.
- Understanding the spectrum of these diseases is crucial for effective management and treatment strategies.
Purpose of the Study:
- To characterize the types and clinical presentations of glomerular diseases in Iranian children.
- To analyze renal biopsy findings in children diagnosed with glomerular diseases.
Main Methods:
- Retrospective analysis of renal biopsy data from 411 children (0.3-18 years) between 1976 and 1985.
- Clinical data including nephrotic syndrome, renal failure, and arterial hypertension were recorded.
- Histopathological and immunofluorescence findings from renal biopsies were examined.
Main Results:
- Nephrotic syndrome (79%), renal failure (43%), and hypertension (38%) were prevalent clinical presentations.
- Focal-segmental sclerosis (56.5%) was the most common biopsy finding, followed by minimal change disease (26.6%).
- Common glomerulonephritis types included mesangiocapillary (80 cases) and lupus (34 cases); IgA nephropathy was uncommon.
Conclusions:
- Glomerular diseases in Iranian children exhibit diverse clinical and pathological features.
- Focal-segmental sclerosis and nephrotic syndrome are significant findings in this pediatric cohort.
- The study highlights the importance of renal biopsy in diagnosing and managing pediatric glomerular diseases.
Abstract:
A total of 411 children, aged from 0.3 to 18 years, suffering from glomerular diseases, were studied by renal biopsy between 1976 and 1985. The clinical presentation included nephrotic syndrome (79% of cases), renal failure (43%), and arterial hypertension (38%). In all, 177 cases presented with primary nephrotic syndrome; all had complicated courses and most were either corticosteroid-dependent or -resistant. Only 26.6% had minimal change disease on renal biopsy; 56.5% had focal-segmental sclerosis; and immunofluorescent deposits were observed in half of the group. Acute poststreptococcal (36 cases), mesangiocapillary (80 cases), and lupus (34 cases) glomerulonephritis occurred frequently; IgA glomerulopathy (10 cases) and haemolytic uraemic syndrome (6 cases) were uncommon. Glomerular crescents were observed in 71 cases. These observations illustrate the types of glomerular diseases seen in Iranian children.
