Abstract：
:The association of Merkel cell polyomavirus (MCPyV) with Merkel cell carcinoma (MCC) in immunocompromised individuals has been revealed in a number of surveys. The study of MCPyV specific antibody titers and viral loads in such patients has a great attraction for research groups interested in viral reactivation. In this cross-sectional study to evaluate MCPyV antibody titer, DNA prevalence and viral load in peripheral blood mononuclear cells (PBMCs), we examined 205 HIV-1 infected patients and 100 un-infected controls. The HIV-1 infected patients divided into two groups (HIV/AIDS and non-AIDS) according to their CD4 status. Total IgG antibody titer against MCPyV was analyzed by virus like particle (VLP)-based enzyme linked immunosorbent assay (ELISA). Presence of MCPyV-DNA in subject's PBMCs was examined by quantitative real-time PCR assay. Levels of anti-MCPyV IgG in HIV/AIDS patients were significantly higher than those in non-AIDS HIV-infected and control subjects (p value = <0.001). The prevalence rate of MCPyV-DNA in PBMCs of HIV/AIDS, non-AIDS HIV-infected and un-infected controls were 17%, 16%, and 14% respectively. The MCPyV viral load among the groups ranged between 0.15 to 2.9 copies/103cells (median, 1.9 copies/103cells), with no significant difference between the studied populations (p value = 0.3).
