It is worth noting that in all subgroups of patients, the median was patients with newly diagnosed HIV infections (we entered 0 for patients with a diagnosis made within a maximum of 1 week), those in the stage of a severe type of immunodeficiency (with the mean value and median of CD4 T-lymphocyte count below 100 cells/mm3), and those diagnosed with CNS opportunistic diseases (Table 8). The gene discussed is CD4; the disease is HIV infectious disease.
