Current guideline-recommended screening for pulmonary hypertension in patients with systemic sclerosis has not been evaluated in systemic lupus erythematosus (SLE), which is disproportionately prevalent in Asians. This multicentre, cross-sectional screening study aims to study the prevalence of pulmonary hypertension among SLE patients using these guidelines, and identify independent predictors and develop a prediction model for pulmonary hypertension in SLE patients. SLE patients from participating centres will undergo an echocardiography- and biomarker-based pulmonary hypertension screening procedure as in the DETECT study. Standard right heart catheterisation will be provided to patients with intermediate or high echocardiographic probability of pulmonary hypertension. Those with low echocardiographic probability will rescreen within 1 year. The primary measure will be the diagnosis and types of pulmonary hypertension and prevalence of pulmonary hypertension in SLE patients. The secondary measures will be the predictors and prediction models for pulmonary hypertension in SLE patients. The estimated sample size is approximately 895 participants. The results of the SOPHIE study will be an important contribution to the literature of SLE-related pulmonary hypertension and may be immediately translatable to real clinical practice. Ultimately, this study will provide the necessary evidence for establishing universal guidelines for screening of pulmonary hypertension in SLE patients.
