Immunosuppressive therapy in lupus‐ and mixed connective tissue disease–associated pulmonary arterial hypertension: A retrospective analysis of twenty‐three cases

Abstract

PAH associated with SLE or MCTD may respond to a treatment combining cyclophosphamide and glucocorticoids. Patients who could benefit from this immunosuppressive therapy could be those who have less severe disease at baseline. For patients with more severe disease, pulmonary vasodilators should be started, possibly in combination with immunosuppressants. In any case, clinical and hemodynamic evaluations are mandatory to monitor the response and adapt the treatment. These retrospective and uncontrolled data need to be confirmed by randomized controlled trials.
