T-cell lymphocytopenia: An omnipresent predictor of morbidity and mortality in consequence of SARS-CoV disease and influenza A infections.

ABSTRACT

PURPOSE OF THE RESEARCH We proposed T-cell lymphocytopenia as a strategic predictor of serious coronavirus and influenza infections. Our preeminent goal was to determine whether a degree of T-cell lymphopenia would identify a distinct threshold cell count to differentiate between severe and non-severe infections. We codified an Index Severity Score to exploit an association between T-cell cytopenia and the grade of disease activity. PRINCIPAL RESULT: A T-cell count of 560 cells/uL or below signified a trend towards advanced disease.
