Insights

The mean platelet volume/platelet count (MPV/PC) ratio may aid in diagnosing pediatric acute appendicitis (AA). While a weak negative relationship exists with white blood cell (WBC) count, receiver operating curve analysis suggests its utility.

Area of Science:

  • Pediatric Gastroenterology
  • Hematology
  • Surgical Diagnostics

Background:

  • Pediatric acute appendicitis (AA) diagnosis is challenging due to age-related variations in abdominal findings.
  • Current diagnostic methods for AA rely on clinical examination, laboratory tests, and imaging, but new parameters are needed.
  • Platelet indices, such as mean platelet volume/platelet count (MPV/PC) ratio, are emerging as potential biomarkers in various inflammatory conditions.

Purpose of the Study:

  • To evaluate the diagnostic value of platelet indices, specifically the MPV/PC ratio, in pediatric patients with acute appendicitis (AA).
  • To explore the relationship between MPV/PC ratio and white blood cell (WBC) count in the diagnosis of AA.
  • To assess the sensitivity and specificity of MPV and MPV/PC ratio in identifying pediatric AA.

Main Methods:

  • Retrospective observational study of 207 pediatric patients undergoing surgery for suspected AA.
  • Patients were categorized into three groups: non-appendicitis, uncomplicated appendicitis, and complicated appendicitis based on surgical and histopathological results.
  • Statistical analysis included comparing MPV/PC ratios across groups and performing receiver operating curve (ROC) analysis for WBC and MPV.

Main Results:

  • No significant difference in MPV/PC ratio was observed among the non-AA, uncomplicated AA, and complicated AA groups.
  • A significant negative correlation (r = -0.239) was found between white blood cell (WBC) count and MPV/PC ratio.
  • Receiver operating curve analysis indicated that both WBC and MPV are significant in diagnosing pediatric AA, with MPV showing 61.8% specificity and 68.8% sensitivity.

Conclusions:

  • The MPV/PC ratio demonstrates a weak, negative association with WBC count in pediatric appendicitis.
  • Despite the weak correlation, the MPV/PC ratio shows potential as a useful diagnostic parameter for pediatric AA, as suggested by ROC analysis.
  • Further research may elucidate the precise role of platelet indices in the diagnostic algorithm for pediatric appendicitis.
