Clinical Manifestations and Management of Nephritic Syndrome
Key Clinical Features
- Nephritic syndrome in children presents with hematuria, hypertension, edema, oliguria, and azotemia, requiring only supportive care with fluid/sodium restriction and blood pressure management, as the condition is typically self-limited 1
- The American Academy of Pediatrics recommends supportive care exclusively for nephritic syndrome, with no immunosuppression indicated 1
- Nephritic syndrome differs fundamentally from nephrotic syndrome, presenting with inflammatory glomerular injury (hematuria, hypertension, azotemia), while nephrotic presents with podocyte injury (massive proteinuria, hypoalbuminemia, hyperlipidemia, severe edema) 2, 3
Initial Management Approach
- The American Academy of Pediatrics recommends fluid restriction, sodium restriction, and antihypertensive therapy as needed for blood pressure control in nephritic syndrome 1
- Monitor for complications, including acute kidney injury progression, severe hypertension, and fluid overload 1
- Antibiotics should only be prescribed if an active streptococcal infection is documented, with penicillin for 10 days if post-streptococcal glomerulonephritis is confirmed 1
Expected Clinical Course
- Most children recover completely within 2-4 weeks without immunosuppression, as nephritic syndrome is self-limited 1
Key Differentiating Laboratory Findings
- Nephritic syndrome is characterized by hematuria with RBC casts, mild proteinuria, normal or mildly reduced albumin, and elevated creatinine 1
- Nephrotic syndrome is characterized by massive proteinuria, severe hypoalbuminemia, hyperlipidemia, and minimal hematuria 2, 3
