Insights

Inflammatory markers like neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were elevated in children with brucella arthritis (BA). These findings suggest NLR and PLR may serve as indirect indicators of inflammation in BA cases.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Rheumatology

Background:

  • Brucellosis is a multisystem infectious disease characterized by inflammation and elevated acute-phase reactants.
  • Biomarkers such as mean platelet volume (MPV), platelet distribution width (PDW), red cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) are recognized indicators of inflammation.

Purpose of the Study:

  • To evaluate the diagnostic utility of MPV, PDW, RDW, NLR, and PLR as inflammatory biomarkers in pediatric brucella arthritis (BA).

Main Methods:

  • A retrospective study involving 64 children diagnosed with BA and 66 healthy controls.
  • Collected demographic data, joint involvement details, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and hematological parameters.
  • Analyzed synovial fluid and serum tube agglutination test results for Brucella, alongside treatment regimens.

Main Results:

  • Children with BA showed significantly higher mean values for PDW, RDW, MPV, NLR, and PLR compared to controls (p < 0.05).
  • A positive correlation was observed between MPV and NLR (R² = 0.192, p < 0.001).
  • The ankle was the most frequently affected joint (53.1%).

Conclusions:

  • Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) appear to be elevated in children with brucella arthritis, serving as indirect markers of inflammation.
  • Further longitudinal research is recommended to solidify the association between these biomarkers and BA.
