Mitral valve infective endocarditis as a manifestation of disseminated Cryptococcus neoformans infection: a case...

Area of Science:

• Infectious Diseases
• Cardiology
• Mycology

Background:

• Infective endocarditis primarily affects heart valves and is associated with various risk factors.
• Bacterial pathogens like Streptococci and Staphylococci are common, while fungal causes are less frequent.
• Candida albicans and Aspergillus spp. are the most prevalent fungal culprits, with Cryptococcus neoformans infections being rare but associated with high mortality.

Observation:

• This report details a rare instance of native valve infective endocarditis caused by Cryptococcus neoformans.
• The patient was a young woman with advanced chronic kidney disease (stage IV) and severe malnutrition.

Findings:

• Cryptococcus neoformans, a fungus, was identified as the causative agent of infective endocarditis on a native heart valve.
• This presentation is unusual, particularly given the patient's young age and specific comorbidities.

Implications:

• This case underscores the importance of considering fungal pathogens, including Cryptococcus neoformans, in infective endocarditis, especially in immunocompromised or debilitated patients.
• It highlights the need for tailored diagnostic and treatment strategies for fungal endocarditis in specific patient populations.
• Further research into risk factors and outcomes of fungal IE is warranted.
