#AI reads Urine# Prediction of COPD exacerbations using urine biomarkers
Published 16 June, 2025
This paper explores the use of urinary biomarkers and artificial neural networks (ANNs) to predict the risk of exacerbations in chronic obstructive pulmonary disease (COPD). In a retrospective study of 55 patients, researchers first screened 10 biomarkers (such as NGAL, CRP, and fibrinogen) from 35 urinary markers, which effectively distinguished stable and exacerbation phases with area under the curve (AUC) values of 0.84 and 0.81 for accuracy in differentiation. In a prospective study, 105 patients underwent daily home urine testing, and an ANN model was developed using data from 85 of them. The optimized 5-biomarker model predicted exacerbations 7 days before clinical diagnosis, with an AUC of 0.89, 95% sensitivity, and 85% specificity within a 13-day window. Home testing devices achieved over 85% compliance and a 93% operational success rate. The study demonstrates the potential of this method for early warning of exacerbations, though larger-scale research is needed to validate its effectiveness and generalizability.
