Identifying key clinical and biochemical predictors of treatment outcomes in inflammatory bowel disease: a real-world evidence study
This study evaluated machine learning models (XGBoost) to predict clinical response and remission for IBD patients treated with vedolizumab and ustekinumab. Analyzing data from 227 patients, the models achieved F1 scores of 0.842 for 26-week response, 0.869 for 52-week response, and 0.649 for 52-week remission. Key predictors included leukocyte count, FCP, CRP, and vitamin B12 levels, with higher inflammatory markers indicating poorer outcomes. The findings highlight the potential of ML for personalized IBD treatment, emphasizing the need for multicenter validation.

The XGBoost models demonstrated strong predictive capabilities for clinical response, particularly at 52 weeks (F1 score of 0.869). While remission prediction was moderate, these results underscore the potential for ML in anticipating patient outcomes.
Critical variables influencing treatment outcomes include leukocyte count, fecal calprotectin (FCP), C-reactive protein (CRP), and vitamin B12 levels. Elevated inflammatory markers generally correlated with poorer responses, while higher vitamin B12 levels were associated with better outcomes.
Fairness analysis revealed some variability across demographic subgroups, especially due to small sample sizes in certain age groups. The retrospective, single-center nature of the study limits generalizability, emphasizing the need for larger, multicenter validation studies and dynamic biomarker tracking.

Personalized IBD Management at Virgen Macarena University Hospital
Context: At Virgen Macarena University Hospital, machine learning models are being piloted to optimize treatment decisions for IBD patients. This real-world evidence study, involving 227 patients from 2015-2022, provides critical insights for personalized care.
Challenge: IBD patients exhibit variable responses to biological therapies like vedolizumab and ustekinumab, leading to suboptimal outcomes and high healthcare costs. Identifying reliable predictors upfront is essential.
Solution: Implementing XGBoost models trained on clinical, demographic, and laboratory data (e.g., FCP, CRP, Vitamin B12) to predict 26- and 52-week clinical response and 52-week remission.
Outcome: The models achieved F1 scores up to 0.869 for 52-week clinical response, demonstrating strong potential to guide more effective drug selection. This data-driven approach aims to reduce ineffective treatments, prevent complications, and improve patient quality of life.
Lesson: Real-world data and interpretable AI (SHAP analysis) are crucial for developing clinically actionable decision support tools. Future multicenter studies are needed for broader validation and integration into clinical workflows.
