Patent ID: 11646098

Abstract:
Technologies are disclosed for determining or predicting the occurrence of a macrophage activation syndrome, such as hemophagocytic lymphohistiocytosis (HLH). A detection of the emergence of and/or a reliable estimation of the likelihood of future significant macrophage activation syndromes, such as HLH, may be determined or predicted from a time series of laboratory and physiologic values to be measured in a patient. Root mean square of successive deviations (RMSSD) is utilized as a surrogate non-parametric measure of the high-frequency power spectral density (PSD) to identify strong statistical associations with the presence and/or near-term future emergence of macrophage activation syndromes. Utilizing these input variables, a model having satisfactory predictive accuracy is constructed using linear discriminant analysis (LDA), gradient boosting, random forest (RF), neural network, logistic regression, or the like, and may be used for the prediction.
