Introduction The human immunodeficiency virus (HIV) primarily targets clusters of differentiation 4 (CD4)+ T cells and other immune cells, leading to immune dysfunction. Cytokines such as interleukin (IL)-23 and IL-27 have complex roles in HIV-associated disease progression, affecting viral replication and immune responses. This study aimed to explore the correlation between HIV-related CD4 lymphopenia and the inflammatory cytokines IL-23 and IL-27 in treatment-naive HIV patients. Materials and methods This is a single-center, prospective, observational study conducted at the Antiretroviral Treatment (ART) Center of Jawaharlal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, Uttar Pradesh, India. Sixty-five treatment-naive HIV seropositive patients were recruited in this study. Quantitative estimation of inflammatory biomarkers (IL-23 and IL-27) was performed using enzyme-linked immunosorbent assay (ELISA). The fluorescent-activated cell sorter count (FACSCount) technology was used to determine the CD4+ T-cell count. Results Our study revealed that HIV-infected individuals had significantly higher levels of IL-23 (868.9±246.7 pg/mL vs 98.3±86.6 pg/mL, p < 0.01) and IL-27 (1629.5±518.5 pg/mL vs 291.3±225.2 pg/mL, p < 0.01) compared to healthy controls. Additionally, we found a strong positive correlation between CD4 count and IL-23 titers (r = 0.93, p < 0.01), as well as between CD4 count and IL-27 titers (r = 0.92, p < 0.01) in HIV-positive individuals. Conclusion The findings suggest that these cytokines respond to HIV infection and may potentially play a crucial role in restraining HIV replication and slowing down the progression of the disease.
