Efecto del consumo de basuca sobre las función fagocítica y microbicida de los polimorfonucleares neutrófilos

The effect of free base cocaine consumption on the phagocytic and microbicidal capabilities of polymorphonuclear neutrophils (PMN) was studied in habitual users and in ex-users of this substance. The opsonic capability of their sera was also determined. Results showed a normal response in all these activities when compared with cells and sera of healthy non-users. Mean percentages of bacteria associated with PMNs of users and controls, using sera of with PMNs of users, 52.9 with those of ex-users, and 49.7 and 53.8 with cells of the respective controls. Percentages of destruction of bacteria associated with PMNs in normal serum were as follows: 47.2 for users; 50.5 for ex-users, and 44.5 and 51.6 for their respective controls.  Although the habitual consumption of free-base cocaine did not affect the phagocytic and microbicidal capabilities of peripheral blood PMNs, it is important to determine the effects of this substance on neutrophils and macrophages of the bronchoalveolar region, since these are the cells that receive maximum exposure to the drug during consumption.
