Management and outcomes of acute post-streptococcal glomerulonephritis in children

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Immunology

Background:

• Acute post-streptococcal glomerulonephritis (APSGN) is a leading cause of acute kidney injury in children, particularly in resource-limited regions.
• It arises from an immune-mediated response to streptococcal antigens, often following pharyngitis.

Purpose of the Study:

• To review the epidemiology, pathogenesis, clinical presentation, management, and prognosis of APSGN in children.
• To identify predictors of disease severity and poor outcomes.

Main Methods:

• Literature review of APSGN, focusing on pediatric cases.
• Analysis of clinical features, diagnostic markers, and treatment strategies.
• Identification of prognostic indicators such as renal biopsy findings and presenting renal function.

Main Results:

• APSGN presents with varied renal syndromes, including nephritic, nephrotic, or rapidly progressive forms, and can be subclinical.
• Management is primarily supportive, addressing fluid overload, hypertension, and renal function.
• Indicators of severity include decreased complement levels, elevated C-reactive protein, hypoalbuminemia, crescent formation on biopsy, and initial renal insufficiency.

Conclusions:

• APSGN is generally a self-limiting condition with a favorable prognosis for most children.
• However, certain factors like crescentic glomerulonephritis and impaired renal function at presentation predict a higher risk of persistent kidney issues.
