Patients in Group I showed lymphopenia with a median lymphocyte count of 0.78 × 109/L in peripheral blood and had significantly lower total T-cell proportion (p = 0.048), CD4+ T-cell counts (p < 0.001), and proportion (p = 0.007) compared with Group II, while PCT (p = 0.017) and ferritin (p < 0.001) were significantly increased compared to Group II. This evidence concerns the gene CD4 and lymphopenia.
