Development of an artificial intelligence-based early diagnostic system for light-chain amyloidosis
This study introduces an AI-based early diagnostic system for light-chain (AL) amyloidosis, a rare and challenging disease to diagnose. Utilizing data from 1,355 patients across 18 hospitals in China, the system leverages routine lab and echocardiography results (10 key variables) and ensemble learning models. It demonstrates significantly higher diagnostic accuracy (95%) compared to physicians (73% for hematologists, 65% for other specialists), offering a promising tool for earlier and more precise disease management and improved patient outcomes in various clinical scenarios.

Artificial intelligence is transforming healthcare by improving diagnostic accuracy, personalizing treatment plans, and enhancing operational efficiency. In rare diseases, AI offers the unique potential to overcome data scarcity and expertise limitations, accelerating early detection and intervention.
Machine learning algorithms, including ensemble methods, are proving highly effective in medical diagnostics. They can identify complex patterns in diverse patient data, leading to more robust and generalized predictive models than traditional statistical approaches, particularly valuable for conditions with subtle or non-specific markers.
Early disease detection is paramount for effective treatment and improved patient prognosis, especially for rapidly progressing or rare conditions. AI systems can serve as crucial early warning tools, integrating routine clinical data to identify high-risk individuals and prompt timely specialist referral, significantly reducing diagnostic delays.

AI for Rare Disease Diagnostics
Summary: Light-chain (AL) amyloidosis is a rare disease with challenging early diagnosis due to non-specific symptoms and low physician awareness, leading to significant diagnostic delays and poor prognosis.
Challenge: Develop a safe, economical, and feasible early diagnostic system that can accurately identify AL amyloidosis using readily available clinical data, overcoming limitations of traditional methods and specialist dependency.
Solution: An AI-based diagnostic assistance system was developed using gradient boosting decision tree, support vector machine, random forest, and ensemble learning models. It leverages ten routine variables (age, cTnl, NT-ProBNP, Crea, ALB, Tbil, ALP, IVS, LVPW, EF) from a large, multi-center patient dataset.
Results: The ensemble learning model achieved an F1 score of 0.94 and AUC of 0.9784, demonstrating superior accuracy (95%) compared to human physicians (73-65%). This model can predict AL amyloidosis probability in various scenarios, supporting earlier diagnosis and improving patient outcomes.
