[Show abstract][Hide abstract] ABSTRACT: The patient described here is a 21-year-old Japanese woman with primary Sjögren's syndrome (pSS) presenting with worsening of dyspnea, palpitation, recurrent parotitis, and arthritis. Chest computed tomography showed diffuse interlobular septal thickening and ground-glass opacities. Right heart catheterization demonstrated pulmonary hypertension, right-sided heart failure, normal pulmonary capillary wedge pressure, and no evidence of arterio-venous shunt. Transbronchial lung biopsy showed luminal obliteration of pulmonary venules by intimal cellular proliferations, without abnormalities in the small pulmonary arteries. These findings were consistent with pulmonary veno-occlusive disease (PVOD). Immunosuppressive therapy, starting with prednisolone 20 mg/day and subsequently combined with azathioprine, resulted in the disappearance of the signs and symptoms, including exertional dyspnea and abnormal pulmonary parenchymal shadows on computed tomography, and the normalization of pulmonary artery pressure. So far, there have been no reported cases of PVOD associated with pSS. Of interest, immunosuppressive therapy without vasodilator therapy almost completely resolved the pulmonary hypertension in this patient.

[Show abstract][Hide abstract] ABSTRACT: Pulmonary arterial hypertension (PAH) is a devastating complication of systemic lupus erythematosus (SLE). We aim to estimate the putative predictors contributing to early identification of PAH, thus improve appropriate medical intervention and a better prognosis. A retrospective case-control study was conducted. Forty-one SLE patients with PAH and 106 SLE patients without PAH were enrolled. Demographic variables, clinical features, and laboratory data were compared between the two groups. Univariate and multivariate logistic regression models were used to examine the predictors contributing to PAH in SLE. Serositis, Raynaud's phenomenon, high disease activity, anticardiolipin antibodies, and anti-U1RNP were significantly associated with SLE-PAH. Univariate and multivariate analysis showed that Raynaud's phenomenon, anticardiolipin antibodies, and anti-U1RNP were independent predictors of PAH in SLE. This study highlighted the clinical pattern of SLE-PAH patients, and underlined the leading predictors of PAH development among patients with SLE. Routine echocardiography is recommended in SLE patients with the independent predictors mentioned above.
