Alkaline phosphatase as an adjunct for Appendicitis Inflammatory Response score.

Area of Science:

• Medical Diagnostics
• Surgical Pathology
• Biomarker Research

Background:

• Appendicitis is a common surgical emergency requiring accurate diagnosis.
• Current diagnostic methods, including the Appendicitis Inflammatory Response (AIR) score, have limitations, especially in complex cases.
• Alkaline phosphatase (ALP) is an inflammatory marker that may improve diagnostic precision.

Purpose of the Study:

• To evaluate the impact of integrating alkaline phosphatase (ALP) levels into the Appendicitis Inflammatory Response (AIR) score.
• To assess the diagnostic accuracy of the enhanced AIR score in patients with suspected appendicitis.

Main Methods:

• An observational study involving 112 patients with suspected appendicitis.
• Patients were assessed using the AIR score, with and without the inclusion of ALP levels.
• Statistical analysis included sensitivity, specificity, NPV, PPV, and ROC curve analysis.

Main Results:

• The AIR score showed an initial sensitivity of 80% and specificity of 75%.
• Integrating ALP improved sensitivity to 92% and specificity to 85%.
• Area Under the Curve (AUC) improved from 0.78 to 0.92 with ALP, with an optimal ALP cutoff of 90 IU/L.

Conclusions:

• Integrating ALP into the AIR score significantly enhances diagnostic accuracy for appendicitis.
• ALP shows potential as a valuable biomarker for improving appendicitis diagnosis.
• This enhancement can lead to better clinical decision-making, reduced surgeries, and improved patient outcomes.
