Insights
Acute postinfectious glomerulonephritis (PIGN) in children usually resolves quickly. This case highlights a rare protracted PIGN with persistent symptoms, requiring a renal biopsy for diagnosis.
Area of Science:
- Pediatric Nephrology
- Immunology
- Pathology
Background:
- Acute postinfectious glomerulonephritis (PIGN) commonly follows streptococcal infections in children.
- PIGN typically presents as a self-limiting condition with a favorable prognosis.
Observation:
- A previously healthy 4-year-old boy presented with prolonged PIGN symptoms.
- The patient experienced recurrent gross hematuria, proteinuria, and low C3c complement levels with normal creatinine.
Findings:
- Renal biopsy after 6 months revealed pathology consistent with acute endocapillary glomerulonephritis.
- The protracted course and nephrotic-range proteinuria prompted the biopsy.
Implications:
- This case underscores the possibility of atypical PIGN presentations in children.
- Understanding protracted PIGN is crucial for accurate diagnosis and management.
- Highlights the importance of renal biopsy in complex pediatric glomerulonephritis cases.
Abstract:
Acute postinfectious glomerulonephritis (PIGN) affects children typically after upper respiratory tract or skin infections with streptococci but can complicate the course of other infections. In children, it is generally a self-limiting disease with excellent prognosis. This paper reports a previously healthy 4-year-old boy who experienced a protracted course of PIGN with persisting episodes of gross haematuria, proteinuria, decreased complement C3c levels but normal P-creatinine levels. Due to the protracted course and the nephrotic-range proteinuria, a renal biopsy was performed 6 months after the initial presentation and the overall pathology was consistent with acute endocapillary glomerulonephritis.
