CD4 count

Absolute T4 count AIDS The number of 'helper' T cells/mm3 in Pts with HIV, which declines as infection progresses; the absolute CD4 count was the standard lab parameter used to monitor the immune suppression in persons with HIV; HIV RNA levels are more valid markers of immune responsiveness, and are the gold standard for Pts with AIDS/HIV infection

Priority should be given to all children younger than 5 years old regardless of CD4 cell count or clinical stage, and children with severe or advanced HIV clinical disease (WHO clinical stage 3 or 4) and/or those with a CD4 count <350 cells/[micro]l.
170 ELISA-positive HIV patients of either sex, age ranging from 15 to 60 years, having any stage of the disease irrelevant of the CD4 count, were included in the study.
Cox regression models adjusted for age, race/ethnicity, smoking, HCV infection, alcohol or drug use, and history of chronic obstructive pulmonary disease (COPD) or occupational lung disease identified three immune predictors of incident lung cancers in 12-month time-lagged analyses: low CD4 count, low CD4/CD8 ratio, and high viral load (HIV RNA) (Table 2).
HIV experts in the United States (2) and around the world (3) recommend starting antiretroviral therapy as soon as a person tests positive for HIV--no matter what CD4 count that person has.
Noninvasive markers of dipstick urine abnormality findings such as proteinuria, leukocyturia, and hematuria were found to be significantly associated with a declined CD4 count [18].
[9] In a recent NDoH circular [10] (September 2016), eligibility criteria for UTT clearly state that baseline monitoring of the CD4 count is the 'key factor in determining fast-tracking and prioritization of patients with CD4 <350 and CD4 <200 cells/[micro]l into care', and eligibility for opportunistic infection prophylaxis is defined as a CD4 count of <200 cells/[micro]L and that for cryptococcal disease screening at <100 cells/[micro]L.
A similar finding was reported from studies carried out in France and Brazil, wherein patients with CD4 count of <200 cells/ul were more likely to be seropositive as compared to those with CD4 counts higher than 200 cells/ul, [21, 22] similar correlation between low CD4 counts and toxoplama seropositivity has been reported by Anuradha and Preeti, in their study carried out in Telangana, India, and also in a similar study carried out in Tamil Nadu, India where CD4 counts <100 were found to be significantly associated with seropositivity.
The mean CD4 count for participants with this disorder was 142 cells/[mm.sup.3] with a mean viral load of 20,308 copies/mL.
The groups were CD4 counts less than 200 [mm.sup.-3], between 200 and 499 [mm.sup.-3], whereas the third group consisted of patients with CD4 count above 500 [mm.sup.-3].
