Diagnostic strategy for tuberculous pericarditis in resource-limited settings
1Department of Respiratory Medicine, Xiuzhou District People's Hospital, Jiaxing, Zhejiang, China.
Diagnosing tuberculous pericarditis requires a combination of adenosine deaminase (ADA) tests, interferon-gamma release assays (IGRA), and fluid cultures. This diagnostic triad aids in timely treatment initiation for tuberculosis.
Area of Science:
- Medicine
- Infectious Diseases
- Cardiology
Background:
- Tuberculous pericarditis is a serious condition often misdiagnosed.
- Prompt diagnosis is crucial for effective treatment and improved patient outcomes.
Purpose of the Study:
- To highlight a practical diagnostic approach for tuberculous pericarditis in resource-limited settings.
- To emphasize the utility of a diagnostic triad for early tuberculosis detection.
Main Methods:
- Case presentation of a 58-year-old woman with fever and dyspnea.
- Analysis of pericardial fluid for adenosine deaminase (ADA) levels and interferon-gamma release assay (IGRA) results.
- Isolation of Mycobacterium tuberculosis from pericardial fluid culture.
Main Results:
- Pericardial fluid showed elevated ADA (47 U/L) and a positive IGRA.
- Mycobacterium tuberculosis was confirmed via culture.
- Initial misdiagnosis as pneumonia/heart failure delayed appropriate treatment.
Conclusions:
- A diagnostic triad of ADA, IGRA, and culture is effective for tuberculous pericarditis.
- This approach is valuable in settings without advanced molecular diagnostics.
- Timely diagnosis enables prompt initiation of antitubercular therapy.
