AI model predicts which MS patients will face severe disability
Researchers have developed a method to forecast disease progression in multiple sclerosis patients, potentially allowing earlier interventions to prevent disability. The advance could reshape how neurologists monitor MS and help pharmaceutical companies design more targeted clinical trials.
Originaltitel: Disease phenotype prediction in multiple sclerosis
<p>Progressive multiple sclerosis (PMS) is currently diagnosed retrospectively. Here, we work toward a set of biomarkers that could assist in early diagnosis of PMS. A selection of cerebrospinal fluid metabolites (n = 15) was shown to differentiate between PMS and its preceding phenotype in an independent cohort (AUC = 0.93). Complementing the classifier with conformal prediction showed that highly confident predictions could be made, and that three out of eight patients developing PMS within three years of sample collection were predicted as PMS at that time point. Finally, this methodology was applied to PMS patients as part of a clinical trial for intrathecal treatment with rituximab. The methodology showed that 68% of the patients decreased their similarity to the PMS phenotype one year after treatment. In conclusion, the inclusion of confidence predictors contributes with more information compared to traditional machine learning, and this information is relevant for disease monitoring.</p>
