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.

RESUMO

Os estreptococos beta-hemolíticos do grupo A são os agentes mais comumente envolvidos na glomerulonefrite aguda pós-infecciosa. Relatamos um caso de glomerulonefrite pós-estreptocócica aguda associada a um abscesso orbitário secundário à sinusite, em menino de 11 anos de idade, o qual foi tratado com ceftriaxona e clindamicina endovenosas e drenagem cirúrgica. Doze dias após tratamento de suporte, a função renal se normalizou. Também discutimos a importância desta grave e potencial complicação não supurativa das celulites orbitárias causadas pelos estreptococos beta-hemolíticos do grupo A.

INTRODUCTION

Sinus-related orbital cellulitis is a serious condition that can lead to several intracranial and ophthalmic complications(1). Hypocomplementemic acute glomerulonephritis (AGN) is an immune disorder that is commonly seen in children with infectious diseases caused by a variety of microorganisms, especially Group A b-hemolytic streptococci(2-3). We describe a case of AGN associated with sinus-related orbital cellulitis.

 

CASE REPORT

A previously healthy 11-year-old boy was evaluated for an acute inflammation in the right orbit. On examination, the right eye was proptotic (Hertel measurements were 22 and 12 mm) with swelling of the upper and lower eyelids. Ocular motility was limited in all gaze directions. Visual acuity was 20/40 of the right eye (OD) and 20/25 of the left (OS). Intraocular pressure was 40 mmHg in OD and 12 mmHg in OS. Orbital computed tomography (CT) disclosed a right inferomedial orbital abscess and ipsilateral pansinusitis (Figures 1 and 2). A cantholysis was performed on the OD during admission. The next day the boy underwent middle turbinate resection and ethmoidal and maxillary sinus drainage under general anesthesia. The orbit was approached by an inferior fornix transconjunctival incision. Abundant pus was aspirated from the orbit and sinuses. The culture grew positive for Group A b-hemolytic streptococci. The patient was treated with parenteral antibiotics (ceftriaxone and clindamycin) and five days after surgery he was discharged with full recovery of eye motility and complete resolution of proptosis. Four days after discharge the child presented with facial edema and signs of distress. A pediatric evaluation disclosed generalized edema and systemic hypertension (200 x 100 mmHg), with no other cardiac findings. Blood count, antinuclear antibody, rheumatoid factor, LE cells and serologic tests were within normal limits. Urinalysis showed hematuria and mild proteinuria. Seric complement component levels C3 and C4 were low. The patient was diagnosed as having acute poststreptococcal glomerulonephritis and was treated with furosemide, nifedipine and salt and fluid restriction. The outcome was favorable and after 12 days of hospitalization the boy was discharged without any signs of renal dysfunction, and with increase of complement levels afterwards.

 

 

 

 

DISCUSSION

Postinfectious acute glomerulonephritis may be induced by several bacteria including S. aureus, S. epidermidis, meningococcus, atypical mycobacterium, and Corynebacterium(2). However, group A β-hemolytic streptococcus is the most common causative agent implicated, mainly after acute pharyngitis. AGN is not a common complication, with a frequency less than 5% after a streptococcal infection(2,4). These associations are usually sporadic, notwithstanding they may present in epidemic events in some countries. A progressive renal disease is quite rare and a complete recovery with normal diuresis occurs in more than 90% of treated cases(4).

The pathogenesis of the disease is linked to the production of specific bacterial antigens which are targeted by the host immune response. Immune complexes are then formed and deposited within the glomeruli, activating the complement cascade and attracting inflammatory cells. The resulting inflammatory reaction provokes proliferation of mesangial and endothelial cells and produces bloodless glomeruli, a decrease in renal filtration and retention of fluid and salt(2-3).

The association between sinus-related orbital cellulitis and AGN seems to be quite rare. In a literature search using the Medline database we could not find any report on this association. AGN is usually controlled with supportive measures. However, when the disease is not recognized, serious effects such as congestive heart failure may ensue. The present report highlights the necessity of clinical evaluation of any children with sinus-related orbital cellulitis. Ophthalmologists should be aware that orbital infections can induce renal complications.
