| | In this pilot study 84 HIV negative healthy volunteers (56 males, 28 females) in the age group of 20-59 yr and who were willing to participate in the study were enrolled after proper counseling. Blood specimens were collected from each subject and processed for anti-HIV antibodies for exclusion of HIV. CD4 and CD8 counts of the samples were performed by fluorescence activated cell sorting (FACS). The mean +/- SD of the absolute numbers of CD4 and CD8 lymphocytes/microliter was 763.6 +/- 226 and 547.5 +/- 190 in males and 797.9 +/- 263 and 567.7 +/- 250 in females. The range of the CD4 and CD8 counts was 365-1328 and 264-991 in males and 415-1257 and 224-1126 in females respectively. The mean +/- SD of the CD4:CD8 ratio was 1.47 +/- 0.42 in males and 1.52 +/- 0.45 in females. The results of this study showed that there is wide variability in CD4 count in our population, as is seen in studies reported from other parts of India. A large multicentric study could define the normal range for CD4 and CD8 counts and CD4:CD8 ratio in the Indian population. |
