We conducted a retrospective study of 58 cases of cryptococcosis (1986-2008) with urine test positive for Cryptococcus sp, in Mycology Laboratory, Santa Casa-Hospital Complex, Porto Alegre, RS, Brazil. The diagnosis of cryptococcuria was based on microscopic examination and culture of urinary sediment. Cryptococcus was isolated from other clinical specimens such as blood, cerebrospinal fluid, ascitic and pleural fluids, respiratory secretions, biopsies of skin, nasal and bone marrow. Cryptocccus neoformans was present in 55 cases and Cryptocccus gattii in three cases. Males predominated (79.3%); age ranged from 12 to 86 years. Acquired Immune Deficiency Syndrome (AIDS) were present in 60.3%, 31.1% did not have AIDS and 5.2% were apparently immunocompetent patients. The most frequent signs and symptoms were headache (53.4%) and fever (51.7%). The most widely used medication was the amphotericin B (43 patients). The mortality rate was 45%. We conclude that the mycological examination of the urine can be an alternative simple, non-invasive and useful in diagnosis of disseminated cryptococcosis, especially when used in conjunction with techniques for demonstration of the capsule (nigrosine) and/or production of melanin in special culture media (Staib agar).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
