Brief Summary

Human immunodeficiency virus (HIV) infection is characterized by persistent immune activation and a constant turnover of T cells. This leads to a precipitous fall in the number of T cells, as well as to an early immunosenescence. This results in increased susceptibility to opportunistic infections. In these patients, modulation of the immune response represents a promising mechanism to maintain immunological homeostasis and prevent the development of pathology. We hypothesize that the addition of pyridostigmine to the regular combined antiretroviral therapy will result in a decrease in T cell overactivation and a reduction in circulating inflammatory markers.
