Severe staphylococcal sepsis in Nigerian children: a report of 27 cases

Area of Science:

• Pediatric Infectious Diseases
• Bacteriology
• Clinical Medicine

Background:

• Staphylococcal sepsis is a serious bloodstream infection that can affect children.
• Understanding the clinical spectrum and risk factors is crucial for timely diagnosis and management.
• Previous studies have highlighted the severity of staphylococcal infections in pediatric populations.

Purpose of the Study:

• To describe the clinical manifestations of severe staphylococcal sepsis in children.
• To identify common complications associated with staphylococcal sepsis in this age group.
• To investigate the relationship between staphylococcal sepsis and hemoglobin genotype.

Main Methods:

• Retrospective case series analysis.
• Involved reviewing records of 27 children diagnosed with severe staphylococcal sepsis over a 6-year period.
• Clinical data, including manifestations and outcomes, were extracted and analyzed.

Main Results:

• The most common clinical manifestations included anemia, osteomyelitis, lung infection, and purulent pericarditis.
• Osteomyelitis was severe and multifocal in many cases, resulting in bone and joint deformities.
• All affected children were previously healthy; 83.3% had normal hemoglobin genotype AA, and none had homozygous sickle cell hemoglobin SS.

Conclusions:

• Severe staphylococcal sepsis presents with diverse clinical features in children, with osteomyelitis being a significant concern.
• The absence of sickle cell disease (hemoglobin SS) in affected children suggests it is not a primary risk factor.
• Further research into the pathogenesis and management of staphylococcal sepsis in previously healthy children is warranted.
