To better emulate AIDS patients, SCID mice were infected intravenously with<jats:italic>Cryptococcus neoformans<\/jats:italic>. Mice received no therapy, 3 mg of amphotericin B (AmB) per kg of body weight, or 10<jats:sup>5<\/jats:sup>U of IFN-\u03b3 alone (prophylactically and therapeutically or only therapeutically) or with AmB. In the first experiment, &gt;75% of the mice survived. Therapy with AmB alone was efficacious compared to no therapy in all organs. Both regimens of IFN-\u03b3 alone were efficacious in the brain and lungs, and the combination of AmB and IFN-\u03b3 showed significant synergy in the kidneys. AmB alone cured 40% of mice of infection, whereas the combination regimens cured &gt;50% of the mice and 90% of the brain infections. In a second study, IFN-\u03b3 again proved efficacious alone, and when given with AmB its efficacy was improved. Therapeutic IFN-\u03b3 alone was effective only in the liver compared to no therapy, and the combination regimen, although highly effective, showed no significant synergy. In a third experiment, AmB alone or in combination with IFN-\u03b3 prolonged survival compared to no therapy or IFN-\u03b3 alone. The combination regimen showed significant synergy over AmB alone in the brain, liver, kidneys, and lungs. AmB alone cured no mice of infections in more than two organs, whereas AmB in combination with IFN-\u03b3 cured 55% of infections in three or more organs. These results indicate that IFN-\u03b3 has therapeutic efficacy in severely immunodeficient animals, especially in combination with AmB. Significant synergistic activity was noted in all organs except the spleen. Overall, IFN-\u03b3 has utility as an adjunctive therapy against systemic cryptococcosis in the severely immunocompromised host.<\/jats:p>","DOI":"10.1128\/aac.45.3.686-689.2001","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T10:06:42Z","timestamp":1027764402000},"page":"686-689","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":36,"title":["Efficacy of Recombinant Gamma Interferon for Treatment of Systemic Cryptococcosis in SCID Mice"],"prefix":"10.1128","volume":"45","author":[{"given":"Karl V.","family":"Clemons","sequence":"first","affiliation":[{"name":"<!--label omitted: 1-->Department of Medicine, Division of Infectious Diseases, Santa Clara Valley Medical Center, and California Institute for Medical Research, San Jose, California 95128, and Department of Medicine, Division of Infectious Diseases and Geographic Medicine, Stanford University, Stanford, California 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jon E.","family":"Lutz","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Department of Medicine, Division of Infectious Diseases, Santa Clara Valley Medical Center, and California Institute for Medical Research, San Jose, California 95128, and Department of Medicine, Division of Infectious Diseases and Geographic Medicine, Stanford University, Stanford, California 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Stevens","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Department of Medicine, Division of Infectious Diseases, Santa Clara Valley Medical Center, and California Institute for Medical Research, San Jose, California 95128, and Department of Medicine, Division of Infectious Diseases and Geographic Medicine, Stanford University, Stanford, California 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/iai.63.5.1725-1731.1995"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.38.9.2158"},{"key":"e_1_3_2_4_2","doi-asserted-by":"crossref","first-page":"173","DOI":"10.1093\/infdis\/170.1.173","article-title":"Macrophage colony-stimulating factor induction of enhanced macrophage anticryptococcal activity: synergy with fluconazole for killing.","volume":"170","author":"Brummer E.","year":"1994","unstructured":"Brummer E.
