Trial Outcomes & Findings for Algorithm for Predicting the Unfavorable Course of Sepsis in Children (NCT NCT05908162)

NCT ID: NCT05908162

Last Updated: 2025-12-30

Results Overview

Determination of blood leukocyte subpopulations and their total number in the blood samples (10\^9 cells/l): WBC (leukocytes), CD45+(lymphocytes),CD3+ (T-lymphocytes), CD3- CD16/56+ (NK-cells), CD3+ CD16/56+ (NKT-cells), CD3+ CD4+ (T-helpers), CD3+ CD8+ (T-cytotoxic cells), CD19+ (B-lymphocytes), CD14+ (monocytes): CD14+CD16- (сlassical monocytes), CD14+СD16+(Intermediate monocytes), СD14-СD16+(nonclassical monocytes). Leucocyte count was determined under a microscope in a Goryaev chamber.

PRIMARY outcome

Timeframe: 1 month

Determination of the relative subpopulations of blood leukocytes (percentage of cells of parent population, %): CD45+ (% leukocytes that are lymphocytes), CD3+ (% lymphocytes that are T-cells), CD3- CD16/56+ (% lymphocytes that are NK-cells), CD3+ CD16/56+ (% T-lymphocytes that are NKT-cells), CD3+ CD4+ (% T-lymphocytes that are T-helpers), CD3+ CD8+ (% T-lymphocytes that are T-cytotoxic cells), CD19+ (% lymphocytes that are B-cells), CD14+ CD16- (% monocytes that are classical), CD14+ CD16+ (% monocytes that are intermediate), CD14- CD16+ (% monocytes that are nonclassical), nCD64+ (% neutrophils that express CD64), mHLA-DR (% monocytes that express human leukocyte antigen-DR (HLA-DR)). Cell samples were counted on a FACSCalibur cytofluorimeter. Data were analyzed using Flowing Software version 2.5.1 or BD FACSDiva 7.0.
