Insights

A rare Candida parapsilosis and Peptostreptococcus infection caused purulent pericarditis in an immunocompetent patient. Surgical pericardiectomy was necessary when drainage failed to resolve cardiac tamponade.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Mycology

Background:

  • Purulent pericarditis is a severe infection of the pericardium, often with high mortality.
  • Candida species can cause invasive infections, particularly in immunocompromised individuals.
  • Co-infections involving fungi and bacteria present unique diagnostic and therapeutic challenges.

Observation:

  • This report details the first documented case of pericardial infection by Candida parapsilosis and Peptostreptococcus species in an immunocompetent, nondebilitated patient.
  • The patient presented with symptoms of cardiac tamponade, indicating significant fluid accumulation around the heart.
  • Initial management with pericardial drainage was insufficient to alleviate the patient's condition.

Findings:

  • The causative agents were identified as Candida parapsilosis and Peptostreptococcus species, a rare polymicrobial etiology for purulent pericarditis.
  • The infection led to severe symptoms of cardiac tamponade, necessitating urgent surgical intervention.
  • Pericardiectomy, the surgical removal of the pericardium, was ultimately required for successful treatment.

Implications:

  • This case highlights the potential for Candida parapsilosis and Peptostreptococcus to cause severe pericardial infections even in immunocompetent hosts.
  • It underscores the importance of considering polymicrobial etiologies, including fungal-bacterial co-infections, in refractory cases of purulent pericarditis.
  • The findings emphasize the critical role of prompt and aggressive surgical management, such as pericardiectomy, in life-threatening cases of infectious pericarditis unresponsive to less invasive treatments.
