Insights
The Hematologic Inflammatory Index (HII) showed higher values in pediatric appendicitis cases but lacked the accuracy for reliable standalone diagnosis or surgical guidance. Further research is needed for effective pediatric appendicitis management.
Area of Science:
- Pediatric Surgery
- Clinical Diagnostics
- Inflammatory Markers
Background:
- Appendicitis is the most common surgical emergency in children, necessitating early and accurate diagnosis.
- Preventing complications and improving outcomes hinges on precise recognition of appendicitis.
Purpose of the Study:
- To evaluate the diagnostic performance of the Hematologic Inflammatory Index (HII) in children with suspected appendicitis.
- To assess HII's utility in guiding surgical decisions for pediatric appendicitis.
Main Methods:
- A study involving 349 pediatric patients (5-18 years) with abdominal pain.
- Comparison of laboratory markers, including HII, between confirmed acute appendicitis (AA) and non-acute appendicitis (non-AA) groups.
- Receiver-operating characteristic (ROC) analysis to determine HII's diagnostic accuracy.
Main Results:
- Patients with AA showed significantly elevated white blood cells, neutrophil count, C-reactive protein, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and HII.
- HII achieved 78% sensitivity and 62% specificity for predicting AA at a cutoff of >0.86.
- Lower lymphocyte and platelet counts were observed in the AA group.
Conclusions:
- While HII values were higher in pediatric appendicitis, its diagnostic accuracy was insufficient for standalone use.
- HII did not prove to be a reliable tool for guiding surgical decision-making in pediatric appendicitis cases.
Objective:
Appendicitis represents the most frequent cause of emergency abdominal surgery in children. Early and precise recognition is essential to prevent complications and improve clinical outcomes. The research aimed to investigate the diagnostic performance of Hematologic Inflammatory Index (HII) in children suspected of appendicitis, while also evaluating its contribution to surgical decision-making.
Materials And Methods:
A total of 349 patients (aged 5-18 years) admitted with abdominal pain were evaluated. Patients were categorized into 2 groups: cases with histopathologically confirmed acute appendicitis (AA, n=132) and cases with non-acute appendicitis (non-AA, n=217). Laboratory variables, such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and HII were recorded. Hematologic Inflammatory Index was calculated as: HII = platelet / (neutrophil × lymphocyte) × 100. Receiver-operating characteristic analysis was used to assess the diagnostic accuracy of HII.
Results:
Children in the AA group exhibited significantly higher white blood cells, neutrophil count, C-reactive protein, NLR, PLR, and HII values, along with lower lymphocyte and platelet counts, compared with the non-AA group (P < .05). For predicting AA, HII demonstrated a sensitivity of 78% and specificity of 62% at a cutoff value of >0.86.
Conclusion:
Although HII values were higher in pediatric appendicitis cases, the index did not demonstrate sufficient accuracy to serve as a reliable standalone diagnostic tool or to meaningfully guide surgical decision-making.
