CD4 and pneumocystosis: This finding is consistent with several other studies such as those of Lu et al. (2012), who demonstrated low CD counts (<200 cells/μL) and elevated HIV viral loads (from 500 to 5.28 × 107 copies/mL) in 50 AIDS patients with PJP [43], and Williams et al. (1999) who reported that individuals with lower median CD4 cell counts and higher median RNA copies were associated with a significantly higher risk of developing specific opportunistic fungal infections (PJP, CMV and MAC) [44].
