Primary meningococcal pericarditis presenting with tamponade
Abstract:
An unusual case of a patient with primary meningococcal pericarditis presenting with tamponade is reported. tdespite repeated aspiration and appropriate antibiotic therapy with eradication of group C Neisseria meningitidis, pericardial effusion continued to reaccumulate. Institution of high-dosage corticosteroid therapy resulted in rapid resolution of the effusion. Only six other cases of primary meningococcal pericarditis have been reported in the English literature. Early manifestations of this disease are due to bacterial invasion of the pericardium. The later phase of intensive reaccumulation of sterile pericardial fluid may conceivably be related to meningococcal endotoxin and appears to be responsive to corticosteroid or salicylate therapy. Recognition of this phenomenon may obviate the necessity for a pericardiectomy.
Insights
A rare case of meningococcal pericarditis (inflammation of the heart sac) caused cardiac tamponade. Corticosteroids effectively resolved the effusion after antibiotics failed, suggesting endotoxin involvement.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Case Reports
Background:
- Primary meningococcal pericarditis is a rare condition.
- It can present with life-threatening cardiac tamponade.
Observation:
- A patient with meningococcal pericarditis experienced persistent effusion despite antibiotics.
- High-dose corticosteroid therapy led to rapid resolution of the pericardial effusion.
Findings:
- Bacterial invasion causes early pericarditis symptoms.
- Sterile fluid reaccumulation may be linked to meningococcal endotoxin.
- Corticosteroid or salicylate therapy shows promise for later-stage management.
Implications:
- Corticosteroids may offer an alternative to pericardiectomy in select cases.
- Understanding the endotoxin role could guide future treatment strategies.
- Highlights the importance of considering rare causes of pericarditis.
