Pulmonary hypertension (PH) in systemic lupus erythematosus (SLE) is a serious condition often underdiagnosed. Early recognition and targeted therapies combining immunosuppression and vasodilators are crucial for improving outcomes in SLE-PH.
Area of Science:
- Rheumatology
- Cardiology
- Immunology
Background:
- Pulmonary hypertension (PH) is a severe complication of systemic lupus erythematosus (SLE).
- Subtle presentation and overlap with other conditions lead to underdiagnosis and delayed treatment.
- Pathological mechanisms include endothelial injury, inflammation, and vascular remodeling, causing increased pulmonary arterial pressure and right ventricular dysfunction.
Purpose of the Study:
- To review the current understanding of SLE-associated PH.
- To highlight advances in molecular and immunologic research.
- To discuss diagnostic and therapeutic strategies for SLE-PH.
Main Methods:
- Review of molecular and immunologic research findings.
- Analysis of diagnostic modalities including echocardiography, right heart catheterization, and biomarkers.
- Evaluation of current and emerging therapeutic approaches.
Main Results:
- Distinct biological profiles in SLE-PH involve endothelial dysfunction, cytokine imbalance, and autoantibodies.
- Echocardiography and right heart catheterization are key diagnostic tools.
- Biomarkers assist in risk stratification.
- Treatment involves immunosuppression (corticosteroids, cyclophosphamide) and pulmonary vasodilators, with biologics offering potential.
Conclusions:
- SLE-associated PH requires early recognition and multidisciplinary management.
- Precision medicine approaches targeting immune and vascular pathways are promising.
- Integrating novel diagnostic and therapeutic strategies can improve early detection and survival in SLE-PH.
