Insights
Cardiac tamponade is a serious complication in systemic lupus erythematosus (SLE). Pleuritis, anti-nucleosome antibodies, and large pericardial effusions predict tamponade, often managed with immunosuppression.
Area of Science:
- Rheumatology
- Cardiology
- Internal Medicine
Background:
- Cardiac tamponade is a rare but life-threatening complication of systemic lupus erythematosus (SLE).
- Understanding its incidence and risk factors in diverse populations is crucial for timely diagnosis and management.
Purpose of the Study:
- To determine the incidence, identify risk factors, and describe treatment strategies for cardiac tamponade in a large cohort of Indian patients with SLE.
Main Methods:
- A retrospective study was conducted on admitted SLE patients between May 2014 and December 2016.
- Lupus-related serositis was diagnosed after excluding other potential causes.
- Data analysis focused on identifying predictors of cardiac tamponade.
Main Results:
- Of 409 SLE patients, 5.9% developed cardiac tamponade, often as the presenting feature (50%).
- Large pericardial effusions (>20 mm) strongly predicted tamponade (OR: 93.2).
- Pleuritis, anti-nucleosome antibodies, and effusion size were associated with tamponade in smaller effusions.
Conclusions:
- Pleuritis, anti-nucleosome antibodies, and pericardial effusion size are key predictors of tamponade development in SLE patients.
- High-dose immunosuppression, including methylprednisolone and intravenous cyclophosphamide, effectively managed tamponade, reducing the need for surgery in most cases.
Background:
Cardiac tamponade is a rare but life-threatening complication of systemic lupus erythematosus (SLE).
Aims/Objectives:
To describe incidence, risk factors and treatment of cardiac tamponade in a large cohort of Indian patients with SLE.
Methods:
This retrospective study was conducted at the Department of Rheumatology, IPGMER, Kolkata, India from May 2014 to December 2016 on admitted patients with SLE. Lupus-related serositis was diagnosed after excluding other causes, such as infection, malignancy or heart failure.
Results:
Of 409 patients with SLE, pericarditis was diagnosed in 25.4% (104/409) and cardiac tamponade in 5.9% (24/409). Tamponade was the presenting feature of SLE in 50% (12/24). Tamponade occurred in 77.8% (14/18) of large effusions and in 11.63% (10/86) of small-to-moderate effusions. The commonest autoantibody in serum and pericardial fluid was anti-nucleosme antibody. Large pericardial effusion (>20 mm) (Odd's ratio (OR): 93.2, 95% confidence interval (CI): 11.1-782.5, P < 0.001) predicted tamponade. In the subset of patients with small-to-moderate sized pericardial effusion, tamponade was associated with pleuritis (OR: 44.5, 95% CI: 1.6-1243, P = 0.025), anti-nucleosome antibody (OR: 42.9, 95% CI: 1.6-1176, P = 0.026) and size of pericardial effusion (OR: 1.36, 95% CI: 1.04-1.76, P = 0.025). Repeated pericardiocentesis was required in 3 patients and one needed surgical intervention. Immunosuppressives used were: prednisolone with monthly intravenous cyclophosphamide (in 33.33%) and intravenous methylprednisolone with monthly cyclophosphamide (in 50%).
Conclusions:
Pleuritis, anti-nucleosome antibody and size of pericardial effusion predicted development of tamponade. High dose immunosuppression (methylprednisolone and IV cyclophosphamide) alleviated need for surgery in majority.
