[Salivary IgA levels in a group of drug dependent patients]

The authors briefly recall the oral defense factors, particularly the IgAs, and by a clinical research on normal and drugs HIV positive and negative addicts, seek a possible correlation between the above mentioned conditions and the IgAs concentrations. The impossibility in establishing such a correlation and the drugs addicts IgAs/carions incidence ratio's data, emphasize the complexity of the IgAs connected problems.
