Flow Cytometry for the Study of T-Cell Populations in Hemophagocytic Lymphohistiocytosis Associated With Lymphomas

The goal of this study is to explore the associations between T cell activation and the occurrence of hemophagocytic lymphohistiocytosis (HLH) in patients with newly diagnosed lymphomas. The specific aims are: Prediction of Lymphoma-Associated HLH (LA-HLH): Compare flow cytometric T cell activation markers with the H-score to predict LA-HLH. Identification of new markers for predicting HLH in patients with aggressive lymphoma. Description of the incidence rate of LA-HLH. Assessment of the outcomes of LA-HLH identified by flow cytometric analysis or the H-score. This prospective, single-center observational study will include 150 patients newly diagnosed with aggressive lymphoma within one year. Peripheral blood samples will be taken at diagnosis alongside routine blood chemistry tests for flow cytometric analysis of the T-lymphocyte activation profile. Data on disease characteristics will be collected to calculate the H-score, HLH-2004 score, and OHI score for diagnosing HLH. The flow cytometry results will be compared with these scores to evaluate their effectiveness in diagnosing LA-HLH.
