| Sumario: | Background and Objectives: Neurocryptococcosis is a fungal disease that affects mainly immunocompromised patients. Cases in immunocompetent patients have been described in some case reports. However, as its reporting was not mandatory in Brazil until 2020, little is known about its epidemiology in the South Region of the country. The present study had the objective of describing epidemiological aspects related to the disease in presumably immunocompetent patients. Methods: A retrospective and observational study was developed, based on cases of patients who received care in a public hospital in Joinville, Santa Catarina, Brazil, between 2018 and 2019. Patients with a clinical diagnosis confirmed by the presence of the fungus Cryptococcus spp. in cerebrospinal fluid by means of the Chinese ink staining were evaluated regarding clinical aspects, treatment, and complications during hospitalization. Results: The diagnosis of the disease was confirmed for two patients in 2018 and six patients in 2019. All of them showed no apparent factors for immunodeficiency and no evident environmental risk factors. Most were men with an average age of 39 years. Fever and mental confusion were the most common symptoms at admission. The variant C. neoformans was found in 75% of the cases. All patients received amphotericin B for at least 13 days with or without combined fluconazole. Six patients had nephrotoxicity due to amphotericin B, two evolved to in-hospital death, and two had neurological sequelae. Conclusion: Mortality and complications related to the treatment of neurocryptococcosis in immunocompetent people showed high rates in the studied sample. The recent inclusion of this disease as a mandatory reporting pathology can improve epidemiological data, which will be used to achieve better understanding and prevention of this problem. |
