Key result
Immunosuppressed SLE can predispose to life-threatening purulent myopericarditis and cardiac tamponade.
Why the study?
Purulent bacterial pericarditis is a rare condition that can rapidly progress to cardiac tamponade, especially in immunocompromised patients such as those with SLE.
Case Report (n=1)
This case emphasizes the need for prompt recognition of purulent myopericarditis and cardiac tamponade in immunocompromised patients, such as those with SLE.
Clinicians should suspect purulent myopericarditis in immunosuppressed SLE patients with tamponade; case report leaves open need for prospective validation.
BACKGROUND: Purulent bacterial pericarditis (or myopericarditis) is a rare condition that can lead to the development of pericardial effusion and cardiac tamponade. CASE SUMMARY: We report a complicated case of methicillin-sensitive Staphylococcus aureus myopericarditis complicated by cardiac tamponade in a young, immunocompromised patient undergoing treatment for systemic lupus erythematosus (SLE). DISCUSSION: This case highlights how SLE and immunosuppression can predispose patients to rare, life-threatening infections such as purulent myopericarditis. We review potential mechanisms of how bacterial pathogens may seed the pericardial space, as well as different treatment options that should be considered, including intravenous and, in some cases, intrapericardial antibiotic delivery. TAKE-HOME MESSAGES: Purulent pericardial effusions can rapidly develop and progress to cardiac tamponade, hemodynamic instability, and death if not recognized promptly. SLE and immunosuppression are risk factors for the development of this rare condition.

Roslund et al. (2026) conducted a case report in Systemic lupus erythematosus, purulent myopericarditis, and cardiac tamponade (n=1). Immunosuppression and systemic lupus erythematosus was evaluated on Purulent bacterial myopericarditis and cardiac tamponade. Systemic lupus erythematosus and immunosuppression can predispose patients to rare, life-threatening infections such as purulent myopericarditis leading to cardiac tamponade.
