Summary
A novel diagnostic system uses serum metabolic fingerprints to accurately detect ectopic pregnancy (EP) and predict rupture risk. This advancement offers a rapid, effective tool for early diagnosis and improved patient outcomes in early pregnancy care.
Area of Science:
- Reproductive Medicine
- Biomarker Discovery
- Medical Diagnostics
Background:
- Ectopic pregnancy (EP) is a major cause of early pregnancy complications.
- Current diagnostic methods like ultrasound and blood tests lack sufficient sensitivity.
- There is a critical need for improved diagnostic tools for EP.
Purpose of the Study:
- To develop and validate a one-step system for diagnosing ectopic pregnancy (EP).
- To enable early risk prediction for EP rupture.
- To utilize serum metabolic fingerprints (ESF) for enhanced diagnostic accuracy.
Main Methods:
- Utilized nanoparticle-assisted laser desorption/ionization mass spectrometry to capture EP-associated serum metabolic fingerprints (ESF).
- Developed a machine learning model to analyze ESF for EP diagnosis and risk prediction.
- Validated the models on a cohort of 722 participants.
Main Results:
- The diagnostic model achieved an area under the curve (AUC) of 0.913 for EP detection.
- Metabolic biomarkers identified enabled accurate EP diagnosis across clinical profiles (AUC 0.922).
- The rupture risk prediction model yielded an AUC of 0.885, outperforming conventional indicators (AUC 0.702).
Conclusions:
- The proposed system provides a rapid and effective method for early EP diagnosis.
- This approach significantly improves risk stratification for EP rupture.
- The findings represent a key advancement in precision diagnostics for early pregnancy complications.
