Linezolid therapy for pediatric thoracic spondylodiscitis due to Staphylococcus aureus sepsis

Area of Science:

• Pediatric infectious diseases
• Orthopedic surgery
• Critical care medicine

Background:

• Spondylodiscitis, an infection of the vertebral bodies and intervertebral discs, is uncommon in immunocompetent children.
• Staphylococcal sepsis can lead to severe complications, including vertebral osteomyelitis and discitis.

Observation:

• An immunocompetent child presented with fever, paradorsal swelling, pleural effusion, pneumonitis, and dorsal kyphosis.
• Blood cultures identified Staphylococcus aureus, prompting initial antibiotic therapy with ceftriaxone and amikacin, later switched to vancomycin.
• Despite vancomycin, the patient showed progressive dorsal swelling and radiographic evidence of vertebral destruction (D8-D10).

Findings:

• Switching vancomycin to linezolid resulted in clinical improvement.
• The child experienced a complete recovery from spondylodiscitis and sepsis.

Implications:

• This case underscores the importance of early diagnosis and prompt, appropriate antibiotic therapy in pediatric spondylodiscitis, even in immunocompetent individuals.
• Linezolid demonstrated efficacy in treating severe pediatric spondylodiscitis caused by Staphylococcus aureus.
• Recognizing rare complications of staphylococcal sepsis is crucial for effective pediatric patient management.
