Intralymphatic interleukin 2 treatment in patients with acquired immunodeficiency syndrome: preliminary experience in
Patients with opportunistic infections during the course of acquired immunodeficiency syndrome (AIDS) were analyzed for cellular immune functions and found to be severely immunocompromised. In particular, interleukin 2 (IL 2) production appeared to be defect not only qualitatively but also quantitatively. In some of these patients, exogenous IL 2 improved immune response in vitro. Intralymphatically administered highly purified natural IL 2 was given repeatedly (over a time period of ten days) to three of these patients. In two cases, such a treatment course was repeated later. Clinical response - at least in some patients - appeared to be of temporary benefit. Shortly after termination of IL 2 application in two patients an increase of lectin responsiveness as well as improved reactivity in skin testing was noted, encouraging further exploration of IL 2 as an immunostimulatory drug in AIDS patients.
