To better deliver antiretroviral drugs for treating patients with acquired immune deficiency syndrome (AIDS) with poor immune reconstitution, a novel nanopole capsule was designed in this study. Forty-eight patients with AIDS with poor immune reconstitution were chosen as subjects to test their immune state. CD4 + T and Regulatory T cells (Treg) infected with HIV were cultured to test polyethyleneimine (PEI) and polychitosan (PC) drug delivery system efficiency. The infiltration efficiency test was performed to study the drug delivery efficiency of the delivery systems, and the cell numbers of CD4 + T and Treg cells infected with HIV were calculated to evaluate the therapeutic effect. The results showed that patients with AIDS with poor immune reconstitution had lower CD4 + T cell count and higher Treg cell count. Furthermore, the infiltration efficiency of the PC drug delivery system was higher than that of the PEI drug delivery system, and the therapy efficiency of antiretroviral drugs was greatly improved in the PC group. Additionally, the improvement of CD4 + T and Treg cells damaged by HIV was greater in the PC group. Sequentially, the PC system can better deliver and release loaded antiretroviral drugs and may be a better choice for treating patients with AIDS with poor immune reconstitution in the future.
