Utility of Atypical Lymphocytes and Large Immature Cells in Prediction of Dengue Severity
Dr. Mohd Zeeshan, Dr. Pranay Swarnkar
Abstract: Background: There is a clinical imperative to devise metrics to prognosticate dengue severity. Our objective was to determine the association between longitudinal trends in atypical lymphocytes and large immature cell count with platelet count and dengue severity. Materials and methods: Retrospective analysis of longitudinally measured clinical and hematological data from (n = 79) hospitalized dengue patients was done. Results: The cohort consisted of patients with dengue fever without warning signs (DFWOWS) (n = 40, females = 14, and age = 19.9 ? 14.6 years), dengue fever with warning signs (DFWWS) (n = 36, females = 13, and age = 16.1 ? 14.1 years) and severe dengue (n = 3, females = 2, and age = 5.3 ? 4 years). Platelet count increased at a rate of 11, 524 cells/mm3/day, with a slower rate of rise as the severity increased (p = 0.001***). Concurrently hematocrit and neutrophil percentage decreased, while the lymphocyte percentage and white blood cell (WBC) count increased during the hospital stay. Every 1% increase in atypical lymphocyte count (ATY) was associated with a fall in platelet count by 16, 963 cells/mm3 (p = 0.001***). A similar but weaker trend was found for large immature cells (LICs). Conclusion: The data support the usefulness of longitudinal tracking of atypical lymphocyte and large immature cell count for dengue prognosis. The time trends of the hematological parameters indicate the progression of patients from the critical to the recovery phase.
