Interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) have shown synergistic immunomodulatory and anti-tumor effects in preclinical studies. The present study was designed to assess the effects of the combination of these cytokines after autologous bone marrow transplantation (ABMT). Ten patients received rIFN-gamma alone and 13 patients the combination of rIFN-gamma + rIL-2. Patients received transplants because of lymphoma (10 patients), acute leukemia (3 patients) or solid tumors (10 patients). Immunotherapy was started at a median of 67 days after ABMT. All patients received either 5 x 10(6) (8 pts) or 10 x 10(6) IU/m2 (16 pts) rIFN-gamma by subcutaneous injection 3 times weekly for 14 weeks. rIL-2 therapy consisted of 5 cycles of continuous intravenous infusion of 12 x 10(6) IU/m2/day starting 1 week after administration of rIFN-gamma. In the rIFN-gamma group, toxicity was mild and some biological changes were seen (NK/LAK activation, increase of phagocytosis and of NBT reduction). The combination of rIFN-gamma with rIL-2 did not increase the usual rIL-2 toxicity. NK/LAK cytotoxicity was strongly activated after the first cycle of rIL-2 and was maintained until the end of therapy. Granulocyte chemotaxis was defective after cycle 1 but recovered thereafter. We conclude that the administration of rIFN-gamma + rIL-2 is feasible after ABMT. Our data suggest that the combination may have prolonged the immunologic activation provided by rIL-2 and some improvement of the deleterious effects of rIL-2 on granulocyte functions was achieved. Controlled studies are warranted to assess the impact of this strategy on biological response and patient outcome.

This paper reviews evidence for the immune-enhancing effect of Spirulina (Sp) and Selen-Spirulina (Se-Sp) in male Wistar rats. The rats of control group fed half-synthetic diet. Rats of experimental groups consumed the half-synthetic diets with Sp (10 g/kg diet) or Se-Sp (350 microg Se/kg diet) for 2 weeks. Using rats lymphocytes in vitro after phytohemagglutinin stimulation was demonstrated that lymphocytes from Sp and Se-Sp groups secreted of interleukin-2 and interferon-gamma more control group. Induction of interleukin-4 was comparable with once of control group. We believed that Sp and Se-Sp are more effective in stimulating a Th-1--type response and hence potentiates cell-mediated immunity. The immunostimulatory effect of Sp and Se-Sp was confirmed by morphologic and morphometric investigation of rats spleen, also with by NBT-test of peritoneal macrophages.
