The in vitro effects of 3'-azido-3'-deoxythymidine (AZT) (at concentrations of 1, 10 and 100 microM, respectively) on normal human polymorphonuclear cell (PMN) and monocyte-macrophage functional capacities were evaluated. Results show that AZT was able to decrease monocyte phagocytosis only, while PMN polarization, phagocytosis and killing were unaffected by drug pretreatment. Quite interestingly, monocyte-derived macrophages maintained their unaltered phagocytic function in spite of the presence of AZT in overnight cultures, thus indicating that monocytes are more susceptible than macrophages to the antiproliferative effects of AZT. Since our data indicate that AZT affects normal human monocyte phagocytosis, it is advisable to evaluate this immune parameter in HIV+ patients administered with this drug.
