Group 1: 68 HIV-uninfected patients with paracoccidioidomycosis, histoplasmosis, aspergillosis, trichosporonosis and 21 with tuberculosis; Group 2: 149 patients with HIV infection, including seven with histoplasmosis, and one with aspergillosis, and Group 3 with 24 proven cryptococcosis patients. Cross-reactivity of cryptococcal mannans and polysaccharides secreted by Paracoccidioides brasiliensis, Histoplasma capsulatum, and Trichosporon spp has been described in vitro. However, only a few cases of positive LFA tests in aspergillosis, trichosporonosis, candidemia, and bacterial infections sera have been reported. We observed false-positive LFA in 2\/29 aspergillosis specimens but not in other mycoses or tuberculosis. Among 149 HIV-infected patients, three specimens tested positive, two had cytomegalovirus infections, one of whom also had toxoplasmosis and the other, Kaposi's sarcoma; one patient had no opportunistic infections. We observed sensitivities of 0.933 (serum), 0.95 (CSF), and 1.0 (serum or CSF) for LFA, and for all negative controls (N\u00a0=\u00a0217, serum), a specificity of 0.977 and a negative predictive value (NPV) of 0\u2009938. The specificity and NPV were 0.964 and 0\u2009791, respectively, for 55 patients with mycoses; and 0.98 and 0.912 for 149 HIV-infected patients. We confirmed LFA's high specificity and accuracy for the control groups. There were 6.89% of false-positive results for aspergillosis, and no false-positive results for paracoccidioidomycosis, histoplasmosis, tuberculosis, or other bacterial diseases.<\/jats:p>","DOI":"10.1093\/mmy\/myaf068","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T13:26:57Z","timestamp":1753277217000},"source":"Crossref","is-referenced-by-count":5,"title":["\u201cReactivity of Cryptococcal Lateral Flow Assay in Aspergillosis, Histoplasmosis, Paracoccidioidomycosis, Candidiasis, Trichosporonosis, Bacterial and Viral infections\u201d"],"prefix":"10.1093","author":[{"given":"Edite Hatsumi","family":"Yamashiro-Kanashiro","sequence":"first","affiliation":[{"name":"Faculdade de Medicina, Universidade de Sao Paulo Depto de Infectologia e Medicina Tropical, , Sao Paulo ,","place":["Brazil"]},{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly Aparecida","family":"Kanunfre","sequence":"additional","affiliation":[{"name":"Faculdade de Medicina, Universidade de Sao Paulo Depto de Infectologia e Medicina Tropical, , Sao Paulo ,","place":["Brazil"]},{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evanthia Vetos","family":"Mimicos","sequence":"additional","affiliation":[{"name":"Divisao de Molestias Infecciosas e Parasitarias, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vera L\u00facia Teixeira","family":"de Freitas","sequence":"additional","affiliation":[{"name":"Faculdade de Medicina, Universidade de Sao Paulo Depto de Infectologia e Medicina Tropical, , Sao Paulo ,","place":["Brazil"]},{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mussya Cisotto","family":"Rocha","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c9rika Yoshie","family":"Shimoda Nakanishi","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00e1rcia Eiko","family":"Miyachi","sequence":"additional","affiliation":[{"name":"Center for Reference and Training STD\/AIDS , Health Department of the State of Sao Paulo, Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marjorie Vieira","family":"Batista","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigacao Medica em Imunologia (LIM 48), Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]},{"name":"Divisao de Molestias Infecciosas e Parasitarias, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Martinez","sequence":"additional","affiliation":[{"name":"Universidade de Sao Paulo Depto de Cl\u00ednica Medica, Faculdade de Medicina de Ribeir\u00e3o Preto, Depto de Cl\u00ednica Medica, , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo Nobrega","family":"Litvoc","sequence":"additional","affiliation":[{"name":"Divisao de Molestias Infecciosas e Parasitarias, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo , Sao Paulo ,","place":["Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nairo Massakazu","family":"Sumita","sequence":"additional","affiliation":[{"name":"Divisao do Laboratorio Central.
