AIM: In systemic sclerosis (SSc), this single-centre study aimed to define the frequency and association of pulmonary arterial hypertension (PAH), occurring either alone in SSc-PAH or together with interstitial lung disease (ILD-PH).

MATERIAL-METHODS: SSc cases between the years 1990-2011 were reviewed, retrospectively. Patients' clinical, laboratory findings, Modified Rodnan Skin Score and Medsger score, 6-minute walk distance (6MWD), carbon monoxide diffusion test (DLCO), echocardiography, thorax HRCT, and right heart catheterisation findings were recorded.

RESULTS: One hundred and forty-one cases (F/M:124/17, diffuse cutaneous SSc (DcSSc)/limited cutaneous SSc (LcSSc): 84/57) were included in the study with the mean age of 52.70±15.17 years and disease duration of 107.07±99.44 months. PaO₂, FEV1 and FVC were lower in DcSSc (p<0.05) as compared to LcSSc, but DLCO and 6MWD did not differ significantly, between the two forms. Ground glass opacity (64.7%) and interlobular septal thickening (58.8%) were the most frequent findings on HRCT of such subjects. PAH was detected in 34 subjects (24.1%). Seven of them had SSc associated PAH (SSc-PAH) and 27 ILD-PH. Both frequencies were similar between DcSSc and LcSSc. Mean sPAP was higher in SSc-PAH.

CONCLUSION: PAH was observed in approximately one fourth of patients; therefore advanced cardio-pulmonary investigation should be routinely performed in the SSc patients' management.
