| pubmed-article:1685213 | pubmed:abstractText | A number of in vivo and in vitro results suggest that interferons have an antiretroviral effect on HIV. To check this, 15 HIV-positive patients who had no full-blown AIDS, were treated with recombinant interferon alpha 2b (5 mill. IU s. c. three times a week) over a period of six months. Twelve to 16 weeks after the initiation of treatment, an increase in CD 4 lymphocytes (+16%), NK cells (+16%), lymphocytes stimulation by con A (+ 176%), neopterin (+66%), and beta-2-microglobulin (+19%) was observed. By the end of the study, all these parameters had slightly decreased again. In all patients with CD4 lymphocytes greater than 0.2 c/nl, we observed a decrease in p24 antigen levels, but in patients with CD4 lymphocytes less than 0.2 c/nl, an increase. It would thus seem that any antiretroviral effect of IFN (as shown by the p24 antigen parameter) is more pronounced in patients with superior immune parameters. | lld:pubmed |
