PURPOSE: To evaluate the incidence of pediatric Haemophilus influenzae related orbital cellulitis after the routine administration of the H. influenzae vaccine in Saudi Arabia and to identify the most common pathogens, predisposing factors, related complications, and the need for surgical intervention.
METHODS: A retrospective chart review was performed of patients with a discharge diagnosis of orbital cellulitis who presented to the King Abdul Aziz University Hospital, Riyadh, Saudi Arabia. Saudi children born between 2000 and 2016 were included.
RESULTS: Thirty-one cases were included and 8 had positive cultures. No cases of H. influenzae were found. Of all the positive culture, the most common pathogens isolated were Staphylococcus aureus, Streptococcus pneumoniae and group A Streptococcus in 3 cases (37.5%), 2 cases (25%) and 2 cases (25%). The most common predisposing factor was sinusitis in 90.3% of cases. Sixteen patients (51.6%) developed complications. Fifteen patients (48.3%) developed subperiosteal abscesses, 1 patient (3.22%) developed a lid abscess, 2 patients (6.45%) developed recurrent orbital cellulitis, and 1 patient (3.22%) developed persistent strabismus. Only 10 (31.25%) patients underwent surgical intervention during admission.
CONCLUSION: The vaccine seems to be effective at eliminating the orbital cellulitis potentially related to H. influenzae. The most common current pathogens were Gram-positive Staphylococcus and Streptococcus species. Sinusitis remains the most common cause of orbital cellulitis in children. In select cases, medical treatment can resolve the infections however, close observation is warranted.
