Specific Organisms and Therapeutic Regimens

Organism-specific therapeutic regimens for infectious pericarditis are provided below, including those for bacterial infections, viral infections, fungal infections, and mycobacterial infections. [1, 2, 3, 4, 5, 6]

Bacterial infection

Most cases of bacterial pericarditis require percutaneous or surgical pericardial drainage for cure. [7] Early cardiology and cardiothoracic surgery consultation is strongly recommended.

Streptococcus pneumoniae

Penicillin-sensitive

  • First-line treatment: Penicillin G 4 million units IV q4h (penicillin MIC ≤2 µg/mL)

  • Second-line treatment: Ceftriaxone 2 g IV q24h (penicillin MIC >2 µg/mL and susceptible to ceftriaxone)

  • Duration of therapy: 2-6 weeks

Penicillin-resistant or patient with penicillin allergy

  • First-line treatment: Vancomycin 15 mg/kg IV q12h

  • Second-line treatment: Levofloxacin 750 mg IV/PO daily or moxifloxacin 400 mg IV/PO daily

  • Duration of therapy: 2-6 weeks

Staphylococcus aureus

Methicillin-sensitive (MSSA)

  • First-line treatment: Nafcillinor oxacillin 2 g IV q4h or  cefazolin 2 g IV q8h or ceftriaxone 2 g IV q24h

  • Second-line treatment: see agents listed for MRSA below

  • Duration of therapy: 2-6 weeks

Neisseria meningitidis

  • First-line treatment: Ceftriaxone 2 g IV/IM q12h (may reduce to 2 g IV q24h only if concomitant meningitis is ruled out)

  • Second-line treatment: Ampicillin 2 g IV q4h

  • Third-line treatment: Penicillin G 4 million units IV q4h

  • Duration of therapy: 2-6 weeks

  • Duration of therapy: 2-6 weeks

Enteric gram-negative bacilli (community-acquired)

  • First-line treatment: Ceftriaxone 2 g IV q24h

  • Duration of first-line therapy: 2-6 weeks

  • Second-line treatment: Ciprofloxacin 400 mg IV q12 or ciprofloxacin 500 mg PO q12h or levofloxacin 500 mg IV/PO q24h

  • Duration of therapy: 2-6 weeks

Viral infection

See Pericarditis Empiric Therapy

  • If associated with human immunodeficiency virus (HIV) infection, treat with antiretroviral therapy, monitor for immune reconstitution inflammatory syndrome, and screen for opportunistic infections according to CD4 count

  • If associated with hepatitis B or C, treat with antiviral therapy as dictated by specific virus and genotype.

  • If associated with influenza A or B, treat with oseltamivir 75 mg PO BID × 10 doses

Fungal infection

Most cases of fungal pericarditis require percutaneous or surgical pericardial drainage for cure. Early cardiology and cardiothoracic surgery consultation is strongly recommended.

Candida albicans

Non -albicans Candida species

Aspergillus

First-line treatment

  • Voriconazole 6 mg/kg IV q12h × 1d, then 4 mg/kg IV q12h (oral dosage is 200 mg q12h); or posaconazole 200 mg q6h initially, then 400 mg PO q12h once clinically stable

  • Duration of therapy: 2-6 weeks

Second-line treatment

  • Caspofungin 70-mg loading dose, then 50 mg IV q24h; or micafungin 100-150 mg IV daily

  • Duration of therapy: 2-6 weeks

Third-line treatment
