We selected as controls patients with SLE who underwent cardiopulmonary screening to exclude PAH (n=87): we collected demographic, clinical and laboratory features and performed nailfold videocapillaroscopy (NVC).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>All patients with SLE-PAH were women; age and disease duration were not different from patients with SLE without PAH. Lupus anticoagulant (LAC)+and anti-ribonucleoprotein (RNP)+were\u2009more prevalent in patients with SLE-PAH (respectively, PAH 45.0% vs no-PAH 20.5%, p=0.042; PAH 45.0% vs no-PAH 19.5%, p=0.035). No differences were observed for anti-Sm, anti-Ro, anti-La and anti-cardiolipin and anti-beta2GPI antibodies. Among clinical features, mucocutaneous and central nervous system involvement were more prevalent in patients with SLE-PAH than in SLE controls (respectively, PAH 65.0% vs no-PAH 34.5%, p=0.024; PAH 25.0% vs no-PAH 8.0%, p=0.046). Raynaud\u2019s phenomenon (RP) was more prevalent in patients with SLE-PAH than in SLE controls (PAH 60.0% vs no-PAH 13.8%, p&lt;0.001). RP was a predictor of PAH in patients with SLE (OR 3.8 (0.9\u201314.8)). We performed NVC on nine patients with PAH and on controls: we observed a significantly higher prevalence of scleroderma pattern at NVC in SLE-PAH than controls (PAH 66.7% vs no-PAH 9.2%, p&lt;0.001). Patients with SLE-PAH showed a lower number of capillary density and a higher frequency of giant capillaries.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our data showed that LAC+, RNP+, RP and a scleroderma pattern at NVC was indicative for patients with SLE-PAH. Our results pointed to generalised microvascular involvement and a hypercoagulation state in patients with SLE-PAH.
