Abstract

Background: Acute poststreptococcal glomerulonephritis (APSGN) pediatric disorder, usually with hematuria, hypertension, and edema following group A beta-hemolytic streptococcus. Recurrence is very rare, and only a few cases have been reported worldwide. This case highlights an unusual recurrence of APSGN in a child, underscoring the importance of long-term follow-up despite apparent recovery.
Case Presentation: A 6-year-old boy complained of macroscopic hematuria and high ASO (antistreptolysin O) titers (650 IU/ml) after a respiratory infection. He had hypocomplementemia (C3: 0.30 g/l) and mild acute kidney injury (creatinine: 64 μmol/l). Two months later, renal function returned to normal without treatment. Six months later, recurrent hematuria (ASO (antistreptolysin O): 770 IU/ml, C3: 0.6 g/l) developed after another respiratory infection. Even with recurrence, renal function was stable, and symptoms disappeared spontaneously. Kidney biopsy was delayed due to a mild clinical course.
Conclusion: This case demonstrates that recurrent APSGN, although rare, can occur after new streptococcal infections and may present with milder features. Conservative management was effective, but the report underscores the need for continued followup and clinical vigilance in pediatric patients even after apparent full recovery.
