CD4 and chronic kidney disease: Patients with CKD were older (34 (IQR: 31–44) vs. 30 (IQR: 26–36) years, p = 0.028); had higher HIV-1 viral load (169,000 (IQR: 73,700–453,847) cop/mL vs. 52,000 (IQR: 24,650–111,000) cop/mL, p = 0.0001), lower CD4+ T cells count (163 (IQR: 58–300) cells/μL vs. 323 (IQR: 161–552) cells/μL; p = 0.003), lower CD4/CD8 ratio (0.20 (IQR: 0.09–0.33) vs. 0.30 (IQR: 0.14–0.51) p = 0.022), and more advanced CKD stage (47% in stage C and 79% with CD4+  < 200 cells/μL) than non-CKD patients (Table 1).
