Endothelial Biomarkers of Systemic Sclerosis–Associated Pulmonary Hypertension

Arthritis Care Res (Hoboken)Published Cross-sectional study

Authors' conclusion

PTX-3 is a promising biomarker of PH risk status in patients with SSc as well as a possible marker of precapillary PH

Study context

Population
Patients with systemic sclerosis (SSc) (with pulmonary hypertension (PH), at high or low risk for PH) and healthy controls
Participants
18 / 74 / 44 / 10
Exposure
Endothelial biomarkers (ADMA, sEng, PTX-3) across healthy controls, SSc-PH, SSc at high risk for PH and SSc at low risk for PH
  • Healthy controlsn = 18
  • SSc-PHn = 74
  • High risk for PHn = 44
  • Low risk for PHn = 10
Outcome
Serum ADMA, sEng and PTX-3 to determine SSc-PH risk or differentiate SSc-PH subgroups
Methodological detailsbiomarker comparison, ELISA
  • Biomarker comparison
  • ELISA

Main finding

As reported in the abstract

Low risk for PH

27.0

median · IQR 19.0–47.3 · pg/ml

P < 0.003

AUC to differentiate low risk from high risk for PH
0.87 (95% CI 0.76-0.98, P = 0.0002)

Observational data: associations, not effects.

Further findings
