Trends in adverse pregnancy outcomes among women with systemic sclerosis in the United States.

Objectives: We sought to examine temporal trends in adverse pregnancy outcomes among SSc pregnancies in a large nationwide sample.

Methods: We used the National Inpatient Sample (NIS) database from 2000 - 2017 to derive national estimates of delivery-associated hospitalizations in the United States among patients with SSc. Each SSc delivery was matched to 100 non-SSc deliveries by age, delivery year, and race.

Prognostic significance of pericardial effusion in systemic sclerosis-associated pulmonary hypertension: analysis from the PHAROS Registry.

Objectives: Pulmonary hypertension (PH) is a leading cause of death in patients with SSc. The purpose of this study was to determine the prognostic significance of pericardial effusion in patients with SSc-PH.

Methods: Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma (PHAROS) is a prospective multicentre registry which enrolled patients with newly diagnosed SSc-PH from 2005 to 2016.

Endothelial Biomarkers of Systemic Sclerosis-Associated Pulmonary Hypertension.

Objective: Despite efforts at early detection, patients with systemic sclerosis (SSc) pulmonary hypertension (PH) present with advanced disease. We sought to determine whether endothelial biomarkers (asymmetric dimethylarginine [ADMA], soluble endoglin [sEng], and pentraxin-3 [PTX-3]) can determine SSc-PH risk or differentiate between SSc-PH subgroups.

Methods: ADMA, sEng, and PTX-3 were measured by enzyme-linked immunosorbent assay in four groups: 1) 18 healthy controls, 2) 74 patients with SSc-PH, 3) 44 patients at high risk for PH features, and 4) 10 patients with low risk for PH features.

Cytokine signatures differentiate systemic sclerosis patients at high versus low risk for pulmonary arterial hypertension.

Background: Pulmonary arterial hypertension (PAH) affects approximately 10% of patients with systemic sclerosis (SSc) and is a leading cause of death. We sought to identify serum cytokine signatures that risk stratify SSc patients for this potentially fatal complication.

Methods: Subjects at high risk for PAH and with incident PAH based on right heart catheterization (RHC) were enrolled in the multi-center prospective registry, Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma (PHAROS).
