ABSTRACT

Paracoccidioidomycosis is a systemicmycosis caused by the Paracoccidioides brasiliensis fungus, which is endemic in Latin America. Brazil is the country with the highest number of cases. The affection of the central nervous system (CNS), a potentially fatal condition, occurs in 12% of the cases. The following forms of presentation are identified:meningeal, which is unusual;meningoencephalitic; and pseudotumoral, the latter two being more frequent. Imaging tests are essential for the diagnosis, but the histological identification of the fungus is required for confirmation of the pathology. The clinical picture depends on the neuraxial location.We present a case of amale rural worker, with expansive lesions in the CNS compatible with paracoccidioidomycosis.

ABSTRACT

INTRODUCTION: Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS: A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS: Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS: The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.


INTRODUÇÃO: A paracoccidioidomicose (PCM) é a micose profunda mais importante na América do Sul. O comprometimento do sistema nervoso central é grave e pode ocorrer em 12,5% dos casos. Este trabalho tem como objetivo descrever oito casos de neuroparacoccidioidomicose (NPMC) e comparar suas características com pacientes sem envolvimento neurológico, a fim de identificar aspectos singulares da NPCM. MÉTODOS: Uma coorte de 213 casos de PCM foi avaliada na Clínica de Doenças Infecciosas do Hospital das Clínicas da Universidade Federal de Minas Gerais, de outubro de 1976 a agosto de 2008. Dados epidemiológicos, clínicos, laboratoriais, terapêuticos e de seguimento foram registrados. RESULTADOS: Oito pacientes apresentaram NPCM. A prevalência de NPCM observada foi de 3,8%. Um paciente apresentou a forma subaguda da PCM e sete apresentaram a forma crônica. Todos os pacientes apresentaram a forma parenquimatosa. Cerca de 60% dos pacientes provenientes das regiões norte e nordeste de Minas Gerais desenvolveram NPCM. Foi observado o desenvolvimento de NPCM em uma mãe e em seu filho. Os pacientes com NPCM apresentaram perfis demográficos e clínicos similares à descrição da literatura. Quando comparados aos pacientes com PCM, houve diferenças em relação à procedência de tais pacientes e história familiar positiva de PCM. CONCLUSÕES: Os resultados confirmam a importância da avaliação neurológica em pacientes com PCM. Apesar das limitações desse trabalho, as diferenças com relação à procedência dos pacientes e à história familiar apontam para a necessidade de mais estudos para investigar a existência de fatores de susceptibilidade envolvidos no desenvolvimento da NPCM.

ABSTRACT

INTRODUCTION: Neuroparacoccidioidomycosis (NPCM) is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. METHODS: All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. RESULTS: Fourteen (3.8 percent) cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM). A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP) was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. CONCLUSIONS: All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.


INTRODUÇÃO: Neuroparacoccidioidomicose (NPCM) é um termo utilizado para descrever a invasão do sistema nervoso central pelo fungo patogênico Paracoccidioides brasiliensis. NPCM é descrita, esporadicamente, em relatos de casos ou pequenas séries de casos com pouco ou nenhum enfoque no tratamento ou acompanhamento de longo prazo. MÉTODOS: Todos os pacientes com diagnóstico de NPCM entre janeiro de 1991 a dezembro de 2006 foram acompanhados até dezembro de 2009. RESULTADOS: Foram identificados 14 (3,8 por cento) casos de NPCM de 367 pacientes com paracoccidioidomicose (PCM). Regime combinando fluconazol oral e sulfamethoxazol/trimetoprim (SMZ/TMP) foi o tratamento de escolha. Não houve nenhum caso de óbito causado pelo fungo Paracoccidioides brasiliensis.Sequela neurológica foi identificada em 8 pacientes. Durante o seguimento, calcificação residual foi um achado comum de neuroimagem. CONCLUSÕES: Todos os pacientes deste estudo responderam de forma favorável a associação do fluconazol com o sulfamethoxazol/trimetoprim, um esquema terapêutico que deve ser considerado nos casos de NPCM. Sequela neurológica foi um achado relativamente comum, desta forma, a utilização de anticonvulsivantes, assim como foi necessário suporte fisioterápico para um manejo adequado destes pacientes.

ABSTRACT

Este trabalho é o primeiro a realizar uma revisão sistemática dos casos de neuroparacoccidioidomicose disponíveis na literatura. Foram encontrados 257 casos em 81 trabalhos pesquisados pelo MEDLINE e LILACS, com maior número de publicações após as décadas de 1970-1980. Aproximadamente, 93 por cento dos pacientes eram homens, principalmente lavradores, com idade média de 43 anos. O quadro caracterizou-se por sintomatologia motora ou de hipertensão intracraniana. A forma crônica pseudotumoral predominou. O período médio de evolução foi de 4,9 meses. As lesões foram principalmente supratentoriais (66,8 por cento), localizando-se nos lobos frontais e parietais. A biópsia determinou o diagnóstico em 57,2 por cento dos casos e utilizaram-se métodos de neuroimagem em 64,6 por cento deles. Houve grande associação com a forma pulmonar da doença (59,1 por cento). A mortalidade foi de 44,1 por cento e 50,1 por cento dos sobreviventes evoluíram com sequelas, principalmente motoras. Assim, deve-se considerar a neuroparacoccidioidomicose no diagnóstico diferencial dos processos expansivos e meningoencefalíticos do sistema nervoso central para se estabelecer tratamento precoce e evitar seqüelas incapacitantes.


This study is the first systematic review of cases of neuroparacoccidioidomycosis available in the literature. Through searches in the MEDLINE and LILACS databases, 257 cases were found in 81 published studies, mainly after the 1970s-1980s. Approximately 93 percent of the patients were men, especially farm laborers, with a mean age of 43 years. The characteristic symptoms were motor deficits or intracranial hypertension. The chronic pseudotumoral form predominated. The mean period of evolution was 4.9 months. The lesions were mainly supratentorial (66.8 percent), located in the frontal and parietal lobes. The diagnosis was determined by biopsy in 57.2 percent of the cases and neuroimaging methods were used in 64.6 percent of them. A large proportion of the cases were associated with the pulmonary form of the disease (59.1 percent). The mortality rate was 44.1 percent, and 50.1 percent of the survivors developed sequelae, especially motor impairment. Thus, neuroparacoccidioidomycosis should be considered in the differential diagnosis for expansive and meningoencephalitic processes in the central nervous system, in order to establish early treatment and to avoid disabling sequelae.
