Insights
Neonates and infants exhibit distinct clinical features and pathogens in osteoarticular infections. Early recognition of these differences is crucial for timely diagnosis and effective treatment of bone infections in young children.
Area of Science:
- Pediatric Infectious Diseases
- Neonatal and Infant Health
- Musculoskeletal Infections
Background:
- Osteomyelitis and septic arthritis in neonates and infants often present with nonspecific signs, leading to delayed diagnosis.
- Early bone infections in this age group can be subtle and easily missed by clinicians.
Purpose of the Study:
- To analyze the clinical characteristics of osteoarticular infections in neonates and infants.
- To improve the understanding and diagnostic capabilities for these bone infections in young children.
Main Methods:
- Retrospective multicenter study of neonates (0-28 days) and infants (1-12 months) with osteoarticular infections.
- Data collected included clinical features, complications, laboratory results, and causative microorganisms.
- Statistical analysis compared differences between neonates and infants, and regional variations.
Main Results:
- Neonates showed less fever, more localized swelling, and higher rates of humerus infections compared to infants.
- Escherichia coli and Klebsiella pneumoniae were more prevalent in neonates, while Staphylococcus aureus was more common in infants.
- Neonates were more prone to developing septic arthritis.
Conclusions:
- Significant clinical and microbiological differences exist between neonatal and infant osteoarticular infections.
- Further research is needed to enhance diagnostic accuracy and treatment strategies for these distinct pediatric populations.
Objective:
Signs and symptoms of osteomyelitis or septic arthritis in neonates and infants are often nonspecific and early-stage bone infections in infants may often go unnoticed. The objective of this study was to analyze the clinical characteristics of newborns and infants with osteomyelitis and septic arthritis to improve understanding of the disorder and to assist clinicians with diagnosis.
Methods:
A retrospective multicenter study was conducted on neonates (0-28 days old, n = 94) and infants (1-12 months old, n = 415) with osteoarticular infections. Data consisting of clinical characteristics, complications, laboratory outcomes, and the pathogenic microorganisms causing osteomyelitis were tabulated. The statistics were further broken down into two regions and the significant differences between neonates and infants were evaluated and compared to the literature.
Results:
Compared to infants, neonates had significantly lower incidences of fever (p < 0.0001), higher incidences of localized swelling (p = 0.0021), higher rate of infection at the humerus (p = 0.0016), higher percentage of Escherichia coli (p < 0.0001) and Klebsiella pneumoniae (p = 0.0039) infections, lower percentage of Staphylococcus aureus infections (p < 0.0001) and were more likely to develop septic arthritis (p < 0.0001).
Conclusion:
Distinct differences were found between neonatal and infants with osteoarticular infections. Future studies should focus on improving diagnosis and subsequent treatment regimens for younger age groups.
