Purpose : To estimate and stratify CD4 + and CD8 + T-lymphocyte levels in human immunodeficiency virus (HIV) infected (asymptomatic) and acquired immunodeficiency syndrome (AIDS) patients (symptomatic) and correlate the clinical features of the patients with CD4+ and CD8+ lymphocyte level. Methods : Between April 2002 and September 2003, a total of 415 HIV seropositive adult patients (297 males and 118 females) attending Regional Institute of Medical Sciences (RIMS) hospitals were tested for CD4+ and CD8+ T-lymphocytes by fluorescent activated cell sorter (FACS) counter (Becton Dickinson). Symptomatic patients were diagnosed as per NACO clinical case definition. Results : Ranges of 0-50, 51-100, 101-200, 201-300, 301-400, 401-500 and above 500 CD4+ T-lymphocyte per microlitre were seen in 68, 52, 101, 73, 47, 31 and 43 patients respectively whereas CD8+ T-lymphocyte ranges of 0-300, 301-600, 601-900, 901-1500, 1501-2000, 2001-3500 per microlitre were seen in 29, 84, 92, 145, 40 and 25 patients respectively. One hundred and fifty patients were asymptomatic and 265 were symptomatic. CD4/CD8 ratio in asymptomatics and symptomatics were 0.13-1.69 and 0.01-0.93 respectively. Tuberculosis and candidiasis occurred in CD4+ T-lymphocyte categories between 0-400 cells per mL in symptomatics. However, cryptosporidiosis, toxoplasmosis, herpes zoster, cryptococcal meningitis, Pneumocystis carinii pneumonia, penicilliosis and cytomegalovirus retinitis were seen in patients having CD4+ T-lymphocyte less than 200 per mL. Conclusions : CD4+ T-lymphocyte was decreased in both asymptomatic and symptomatic HIV patients, The decrease was greater in symptomatics while CD8+ T-lymphocyte was increased in both except advanced stage symptomatics. CD4:CD8 ratio was reversed in both groups. Opportunistic infections correlated with different CD4+ T-lymphocyte categories.
