ABSTRACT Our objective was to describe the CD4-mediated human immunodeficiency virus (HIV)-specific cell-mediated immunity (CMI) and its virologic and immunologic correlates in children with chronic HIV infection on highly active antiretroviral therapy (HAART). Twelve HIV-infected children on stable antiretroviral therapy with a median level of CD4+ lymphocytes (CD4%) of 25.5% and a median viral load (VL) of 786 HIV RNA copies/ml were enrolled in this study. Nine of these children were also cytomegalovirus (CMV) seropositive. Blood mononuclear cells, stimulated with HIV and CMV antigens, were used to measure lymphocyte proliferation and to enumerate gamma interferon (IFN-γ)-producing CD4+ cells. HIV CMI and CMV CMI were detected in similar proportions of patients and correlated with each other, although the HIV responses were less robust. HIV lymphocyte proliferation significantly increased with lower HIV VL and showed a trend to increase with higher CD4% and longer time on HAART. The in vitro IFN-γ response to HIV or CMV was not affected by CD4%, VL, or HAART. Pediatric patients with established HIV infection on HAART frequently exhibit HIV CMI despite undetectable HIV replication. We concluded that the association between HIV CMI and CMV CMI indicates that the same factors govern responsiveness to either antigen.

Abstract Introduction Human immunodeficiency virus (HIV) infection is a state of profound immunodeficiency. Disorders of hematopoietic system are a common but often overlooked complication of HIV infection. This can manifest at any stage of the disease but more commonly in the advanced stage with low CD4 count. Anemia is the most common hematological abnormality in HIV patients and prevalence ranges from 1.3 to 95%. As HIV disease progresses, the prevalence and severity of anemia also increase. Hence, this study was undertaken to assess the hematological parameters of HIV-infected patients on highly active antiretroviral therapy (HAART) at different treatment durations with the hope to improve the HAART outcome in HIV patients and its correlation with CD4 count. Methods This prospective longitudinal study enrolled 134 HIV-infected patients admitted to or attending the OPD in the Department of Medicine or Antiretroviral Therapy (ART) Center (Center of Excellence), Regional Institute of Medical Sciences (RIMS), Imphal, Manipur, from 2018 to 2020. Complete hemogram, CD4 count, and other related-blood investigations were studied. Results The mean age of the study population was 39.9 ± 11.04 years. Of the 134 patients, 75 (56%) were males and 59 (44%) were females. Twelve (9%) patients had a history of injecting drug use (IDU). TLE (tenofovir, lamivudine, efavirenz) regimen was started on 112 (83.6%) patients and the majority of them (69/134 [51.5%]) had a CD4 count of 200 to 499 cells/mm3, which increased significantly 6 months after HAART to 99 to 1,149 cells/mm3, with a mean of 445 ± 217 cells/mm3. There were significant improvements in hemoglobin (Hb) levels, total leukocyte count (TLC), absolute neutrophil count (ANC), and absolute lymphocyte count (ALC) after HAART indicating a positive correlation with CD4 count (p < 0.05). Thrombocytopenia was observed higher after HAART when compared to baseline. There was a positive correlation between platelet count and CD4 count. However, the mean corpuscular volume (MCV) and erythrocyte sedimentation rate (ESR) had a negative correlation with CD4 count. Conclusion The study inferred a strong positive correlation between CD4 and Hb levels, TLC, ANC, ALC, and platelet count after HAART with improvement in these values as CD4 count increases. Specific treatment intervention based on the changes in the immunohematological profile trends can help prevent most of the adverse effects on HIV patients in our community.
