Effects of Maraviroc (MVC) on HIV-related Kaposi's Sarcoma (KS)

The subjects' Kaposi's sarcoma related lesions will be evaluated during each visit for an increase or decrease in the number of lesions and whether the quality of the lesions show improvement or worsening of the condition.

A biopsy will be taken from the subjects' lesions at baseline and at the end of the study to determine whether there has been a change in CCR5 receptor levels or KSHV levels.

Blood samples will be obtained from the subjects throughout the study at different points to assess if there are any changes in CD4 count or HIV viral load.

Blood and saliva samples will be obtained from the subjects throughout the study at different points to assess if there are any changes in KSHV viral load.

Blood samples will be obtained from the subjects throughout the study and cryopreserved to assess if there are any changes in CCR5 receptor expression in T and B lymphocytes, monocytes, and natural killer cells.

Blood samples will be obtained from the subjects throughout the study and cryopreserved to assess if there are any changes in T cell activation and exhaustion.
