Insights
Systemic steroids safely benefit pediatric orbital cellulitis patients, reducing hospital stays. C-reactive protein (CRP) levels below 4 mg/dl indicate readiness for steroid treatment, improving outcomes.
Area of Science:
- Ophthalmology
- Pediatrics
- Infectious Diseases
Background:
- Orbital cellulitis is a serious infection requiring prompt treatment.
- Systemic steroids are sometimes used, but their benefit and optimal timing remain debated.
- C-reactive protein (CRP) is a marker of inflammation, but its role in guiding steroid therapy for orbital cellulitis is not well-established.
Purpose of the Study:
- To evaluate the efficacy of systemic steroids in pediatric patients diagnosed with orbital cellulitis.
- To determine if C-reactive protein (CRP) levels can serve as a reliable marker for initiating steroid treatment.
- To assess the impact of steroid therapy on hospital admission duration and overall patient recovery.
Main Methods:
- A prospective, comparative interventional study included 31 pediatric patients (ages 1-18) with orbital cellulitis.
- Patients received intravenous antibiotics; those with subperiosteal abscess underwent surgical decompression if indicated.
- Steroid treatment (oral prednisone 1 mg/kg/day for 7 days) was initiated when CRP levels fell below 4 mg/dl; patients not consenting to steroids served as controls.
Main Results:
- Twenty-four patients received steroids, and 7 did not. Steroid recipients had a significantly shorter average hospital stay (3.96 days vs. 7.17 days, p < 0.05).
- Patients treated with steroids after CRP normalization (≤4 mg/dl) had a shorter remaining hospital stay (1.1 days vs. 4.9 days, p < 0.01).
- No significant differences in surgical intervention rates or recurrence were observed. All patients achieved full visual recovery without permanent ocular disability.
Conclusions:
- Systemic steroids are safe and beneficial for pediatric orbital cellulitis, leading to earlier hospital discharge.
- A CRP level of ≤4 mg/dl is proposed as a standardized threshold for initiating steroid therapy.
- This study suggests a specific dosing schedule (oral prednisone 1 mg/kg for 7 days) for children with orbital cellulitis.
Purpose:
To determine both the benefit of systemic steroids in pediatric patients with orbital cellulitis and to assess the usefulness of C-reactive protein (CRP) levels as a marker for starting steroids.
Methods:
Prospective, comparative interventional study. Pediatric patients aged 1 to 18 years admitted to a tertiary care children's hospital with a diagnosis of orbital cellulitis from October 2012 to March 2014 were included in the study. All patients were treated with intravenous antibiotics, and patients with subperiosteal abscess who met previously published criteria for surgical decompression underwent combined transorbital drainage and/or endoscopic sinus surgery. CRP was measured daily as a biomarker of inflammation, and when below 4 mg/dl, patients were started on oral prednisone 1 mg/kg per day for 7 days. Patients whose families did not consent to steroid treatment served as the control group. Patients were followed after discharge until symptoms resolved and all medications were discontinued.
Results:
Thirty-one children were diagnosed with orbital cellulitis during the study period. Of these 31 children, 24 received oral steroids (77%) and 7 did not (23%). There were 19 males and 5 females in the steroid group with an average age of 8.1 years, and 6 males and 1 female in the nonsteroid group with an average age of 7.1 years (p = 0.618). Thirteen patients (54%) in the steroid group and 2 patients (29%) in the nonsteroid group underwent sinus surgery with or without orbitotomy (p = 0.394). The average CRP at the onset of steroid treatment was 2.8 mg/dl (range: 0.5-4). Patients who received oral steroids were admitted for an average of 3.96 days. In comparison, patients who did not receive steroids were admitted for an average of 7.17 days (p < 0.05). Once CRP was ≤4 mg/dl, patients treated with steroids remained in the hospital for another 1.1 days, while patients who did not receive steroids remained hospitalized for another 4.9 days (p < 0.01). In the steroid group, 2 families reported increased hyperactivity in their children while on steroids. There was 1 case in each group of recurrence of symptoms after discharge from the hospital. Average follow-up time was 2.4 months in the steroid group and 2 months in the nonsteroid group (p = 0.996). At last visit, all patients returned to their baseline ophthalmic examination. There were no cases of vision loss or permanent ocular disability in either group.
Conclusions:
Our results give further evidence of the safety and benefit of systemic steroids in children with orbital cellulitis. Futhermore, this is the first study to suggest a standardized starting point (CRP ≤ 4 mg/dl) and dosing schedule (oral prednisone 1 mg/kg for 7 days) for children with orbital cellulitis. Patients who received systemic steroids after CRP dropped below 4 mg/dl were discharged from the hospital earlier than patients who did not receive systemic steroids.
