RESUMO Antecedentes: A neurocisticercose (NCC) é grave problema de saúde pública nos países em desenvolvimento, especialmente na América Latina, Ásia e África. A NCC é considerada a principal causa de epilepsia de início tardio nas regiões endêmicas. Objetivo: Este artigo pretende discutir os recentes avanços no diagnóstico e tratamento da NCC. Métodos: Artigos científicos e livros relevantes serviram de fonte de informação para esta revisão. Resultados: O diagnóstico da NCC é fundamentado nos exames de neuroimagem (ressonância magnética e tomografia computadorizada) e do líquido cefalorraquiano (LCR). Atualmente, praziquantel e albendazole são considerados eficazes na terapêutica etiológica da NCC, mas há intenso debate quanto à validade e segurança desses medicamentos. Conclusão: Pela relativa carência de ensaios clínicos, são necessários novos estudos particularmente randomizados, controlados e com análise de desfechos clínicos a longo prazo para o esclarecimento da polêmica envolvendo a validade da terapêutica parasiticida na NCC.

ABSTRACT Background: Neurocysticercosis (NCC) is a serious public health problem in several developing countries, including those in Latin America, Asia, and Africa. NCC is considered to be the main cause of late-onset epilepsy in endemic areas. Objective: This review summarizes recent advances in diagnosis and therapy of NCC. Methods: Relevant articles and books were reviewed and used as a source of information for this review. Results: The diagnosis of NCC is based upon neuroimaging studies (MRI and computed tomography) and laboratory analysis of the cerebrospinal fluid (CSF). Praziquantel and albendazole are considered parasiticidal drugs against NCC, but there is an intense debate over the value and safety of these drugs. Conclusion: Given the relative scarcity of clinical trials, more comparative interventional studies, especially randomized controlled trials in long-term clinical evolution, are required in order to clarify the controversy over the validity of parasitic therapy in patients with NCC.

ABSTRACT Fluconazole is extensively used for the treatment of candidiasis and cryptococcosis. Among other factors, successful treatment is related to appropriate fluconazole levels in blood and cerebrospinal fluid. In the present study, fluconazole levels were determined in 15 patients, 14 of whom had AIDS and 13 had neurocryptococcosis. The only selection criterion was treatment with fluconazole, which was performed with a generic or similar form of the drug. Fluconazole level was determined by high performance liquid chromatography and the susceptibility profile of Cryptococcus spp. isolated from the patients was assessed by broth microdilution. Blood and cerebrospinal fluid fluconazole levels were found to be related to the fluconazole daily dose, and exceeded the minimum inhibitory concentration of this antifungal for the Cryptococcus spp. isolates. A good correlation was observed between serum and cerebrospinal fluid drug concentration. In conclusion, treatment with non-original fluconazole under usual medical practice conditions results in appropriate blood and cerebrospinal fluid levels of the drug for inhibiting Cryptococcus spp. susceptible to this antifungal drug. The relatively common failures of neurocryptococcosis treatment appear not to be due to insufficient fluconazole levels in the cerebrospinal fluid, especially with the use of daily doses of 400–800 mg.
