Abstract

Introduction: Fungal infections of the central nervous system present a variety of clinical syndromes, such as meningitis, encephalitis, raised intracranial pressure with a nonspecific presentation, and, in the last two decades, have increased the incidence of these fungal infections. Fungal meningoencephalitis is frequently associated with Cryptococcus, but this report stands out for presenting one species of Penicillium genus., Objectives: Here, we present the first case of meningoencephalitis associated with brain injury caused by Penicillium chrysogenum, in a patient who is immunocompetent and was admitted to Hospital Naval Marcílio Dias, Rio de Janeiro, Brazil., Methods: To identify the fungal species, we performed phenotypic and genotypic methodologies, from the culture to the sequencing of internal transcribed spacer region, and β-tubulin gene, a rare fungus in cerebrospinal fluid cultures, belonging to the genus Penicillium, was identified., Conclusion: We highlight the importance of the first report of meningoencephalitis caused by P. chrysogenum in a patient who is immunocompetent, registered in Brazil. We also emphasize the need for further studies to determine an effective treatment with the least possible side effects for patients infected by fungi that are rarely related to the most severe forms of invasive infections., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2022 The Author(s).

Abstract

Background: Paracoccidioidomycosis (PCM) is one of the most important systemic mycoses in Latin America and the leading fungal cause of mortality in non-immunosuppressed individuals in Brazil. However, HIV/PCM co-infection can increase the clinical severity in these co-infected patients. This co-infection is rarely reported in the literature mainly because of the different epidemiological profiles of these infections. Furthermore, PCM is a neglected and non-notifiable disease, which may underestimate the real importance of this disease. The advent of molecular studies on the species of the genus Paracoccidioides has expanded the knowledge regarding the severity and the clinical spectrum in PCM. In this context, the development of studies to describe the association of the Paracoccidioides phylogenetic cryptic species in vulnerable populations, such as HIV-infected patients, appears relevant., Objective: To describe the clinical, epidemiological, therapeutic and prognostic aspects in HIV/PCM co-infected patients, along with the molecular identification of the Paracoccidioides species involved in these cases., Methods: The investigators performed a molecular and clinical retrospective study involving HIV/PCM co-infected patients, from a reference centre for PCM care in the endemic area of Rio de Janeiro, Brazil, from 1998 to 2015. Molecular identification of the fungal strains was done by amplification of partial sequences of arf and gp43 genes., Findings: Of 89 patients diagnosed with PCM by fungal isolation in the culture, a viable isolate was recovered for molecular analysis from 44 patients. Of these 44 patients, 28 (63.6%) had their serum samples submitted for enzyme immunoassay tests for screening of HIV antibodies, and 5 (17.9%) had a positive result. All cases were considered severe, with a variable clinical presentation, including mixed, acute/subacute clinical forms and a high rate of complications, requiring combination therapy. Paracoccidioides brasiliensis S1 was the species identified in all cases., Conclusions: HIV/PCM co-infection can change the natural history of this fungal disease. The authors reinforce the need to include HIV screening diagnostic tests routinely for patients with PCM.
