- AB OBJECTIVES: To determine the range of T-lymphocyte subsets (CD4, CD8,
- and CD4/CD8 ratios) in acutely ill, hospitalized patients and to
- determine whether these concentrations correlate with illness severity,
- survival rate, or immunodepression. DESIGN: Cross-sectional study,
- comparing Acute Physiology and Chronic Health Evaluation II (APACHE II)
- scores and the calculated, disease-specific, predicted mortality rate
- with T-lymphocyte subsets. SETTING: Urban county hospital intensive care
- unit (ICU), serving as the designated trauma center. PATIENTS: One
- hundred two consecutively admitted ICU patients (72 medical and 30
- surgical). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient
- clinical data, APACHE II scores, and their associated predicted
- mortality rate were recorded. Blinded human immunodeficiency virus (HIV)
- and lymphocyte testing was performed on samples from all patients on ICU
- admission. Despite only three (2.9%) of 102 patients testing positive
- for HIV antibodies, 41% (42/102) of patients had CD4 concentrations of <
- 400 cells/microL, and 29% (29/102) had CD4 concentrations of < 300
- cells/microL. Mean CD8 concentrations were even lower, compared with
- normal laboratory values, resulting in a slight increase in CD4/CD8
- ratios, although 16% (16/102) of patients had a CD4/CD8 ratio of < 1.
- CD4 counts were linearly related to total lymphocyte concentrations
- (Pearson correlation coefficient = 0.948), but no relationship was found
- between total lymphocyte or lymphocyte subset counts and APACHE II
- score, predicted mortality rate, or survival rate. CONCLUSIONS: Acute
- illness alone, in the absence of HIV infection, can be associated with
- profound decreases of T-lymphocyte populations. This problem is
- unpredictable and does not correlate with severity of illness, predicted
- mortality rate, or actual mortality rate. No conclusions regarding HIV
- serostatus or survival can be made based on single measurements of
- T-cell concentrations in acutely ill hospitalized patients.
