[Systemic candidiasis with localization in the brain. Anatomo-clinical study of 5 cases]

Insights

Central nervous system involvement in Candida septicaemia is rare, but this study reports five new cases in Brazil. Microscopic examination revealed candidiasis in cerebral lesions, suggesting a potentially underestimated incidence.

Area of Science:

  • Mycology
  • Neurology
  • Infectious Diseases

Context:

  • Central nervous system (CNS) involvement in Candida septicaemia is infrequently reported, with limited cases documented in Brazil.
  • Systemic candidiasis, particularly with cerebral lesions, presents diagnostic challenges, especially in immunocompromised patients.

Purpose:

  • To report five new cases of systemic candidiasis with CNS involvement in Brazil.
  • To highlight the pathological findings and discuss contributing factors to the rising incidence of Candida septicaemia.

Summary:

  • Five patients (four adults, one child) with serious underlying conditions and prolonged antibiotic therapy developed systemic candidiasis with cerebral lesions.
  • Neurological signs were minimal (seizures, neck stiffness). Histopathology revealed microabscesses and granulomata in three cases, while one had gross necrotic lesions.
  • Grocott's methenamine silver stain confirmed Candida as the aetiological agent in all cases. Other organ involvement was noted in three autopsies.

Impact:

  • This study suggests that the frequency of Candida septicaemia in Brazil may be significantly higher than currently reported.
  • Understanding the pathogenesis and incidence of CNS candidiasis is crucial for timely diagnosis and management of invasive fungal infections.

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
