title: Acute hypocomplementemic post-infectious glomerulonephritis as a complication of sinus-related orbital cellulitis: case report.
abstract: Group A beta-hemolytic streptococcus is the most common agent implicated in post-infectious acute glomerulonephritis. We report a case of acute poststreptococcal glomerulonephritis associated with sinus-related orbital abscess in an 11-year-old boy treated with surgical drainage and intravenous ceftriaxone and clindamycin. Twelve days after supportive measures, renal function was normalized. We also discuss this potentially severe nonsuppurative complication of orbital cellulitis caused by group A beta-hemolytic streptococcus.
