Pneumococcal pericarditis: a persisting problem in contemporary diagnosis

S L Berk, P A Rice, C A Reynholds

    The American Journal of Medicine
    |February 1, 1981
    PubMed
    Summary

    Diagnosing Streptococcus pneumoniae pericarditis is challenging, often missed in patients due to non-specific symptoms. Early recognition of this serious bacterial infection requires heightened clinical suspicion.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Internal Medicine

    Background:

    • Pneumococcal pericarditis, an infection of the sac surrounding the heart caused by Streptococcus pneumoniae, is a rare but serious condition.
    • Prompt diagnosis and treatment are crucial for patient outcomes.

    Observation:

    • A review of six patients admitted to Boston City Hospital revealed significant diagnostic delays in pneumococcal pericarditis.
    • Key clinical signs like pericardial friction rubs and cardiomegaly were often absent, complicating diagnosis.
    • Cardiac abnormalities on electrocardiograms and physical exams were non-specific, frequently leading to misdiagnosis as arteriosclerotic heart disease.

    Findings:

    • All six patients experienced delayed or missed diagnoses of pneumococcal pericarditis during their lifetime.

  • The study highlights the elusiveness of diagnosing this condition, consistent with literature reviews since 1945.

    • Implications:

    • Increased awareness and suspicion are needed among clinicians to improve the early detection of pneumococcal pericarditis.
    • Diagnostic criteria may need refinement to better identify this challenging infection.
    • Further research into specific diagnostic markers for pneumococcal pericarditis is warranted.
