RESUMO
<p><b>OBJECTIVE</b>To study the effect of highly active antiretroviral therapy (HAART) on plasma levels of MSP and MCP-1 in AIDS patients.</p><p><b>METHODS</b>Forty Chinese AIDS patients were treated with HAART for 3 months and 84 German AIDS patients with HAART for 3 to 6 years. The pre-treatment and post-treatment plasma levels of MSP and MCP-1 were measured by enzyme-linked immunosorbent assay (ELISA), and their correlations with CD4+ cell counts and viral loads were analyzed.</p><p><b>RESULT</b>The mean levels of MCP-1 were significantly higher and MSP were significantly lower in HIV-infected patients compared with the HIV-negative controls (P <0.01). After HAART for three months, there were no significant changes in the levels of these cytokines. But after long-term HAART (for 3 to 6 y), the level of MCP-1 was increased and that of MSP decreased significantly (P<0.01). There was a negative correlation between MSP and MCP-1 levels, and the same for MSP level and CD4+ cell counts; while there was a positive correlation between MCP-1 levels and CD4+ cell counts.</p><p><b>CONCLUSION</b>The changed plasma levels of MSP and MCP-1 are associated with HIV-1 infection and HAART may reverse the levels of these two cytokines.</p>

Objective:To explore the change of serum interleukin 16 (IL-16) level and the effects of highly-active antiretroviral therapy (HAART) on IL-16 in patients with HIV infection.Methods:77 patients with HIV infection were studied,with fifteen normal subjects studied as controls.The patients were subdivided into stages according to the standards by US Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).Of all the individuals,the CD4+T cells and CD8+T cells and the amout of IL-16 were measured at each stage to find the difference among normal and groups of the patests,and between the groups with and without HAART.Results:The level of CD4+ T cells in the experimental group were lower than that of the control group in of the patients (P
