A COMPLICATION OF CERTAIN SYSTEMIC DISEASES: Pulmonary hypertension (PH) can complicate the progression of certain systemic diseases such as sarcoidosis, histiocytosis X and some vasculites. The mechanisms at the origin of PH are varied and always require rigorous analysis in order to optimise treatment. PH associated with sarcoidosis is essentially related to specific lung parenchymal fibrosis and is poorly responder to corticosteroids. Other mechanisms may be more rarely incriminated (compressive andenopathies, mediastinal fibrosis, florid sarcoidosis concomitant to a pulmonary occlusive vascular disease...). During histiocytosis X, the ventilatory limitation of these patients does not always correlate with the severity of the respiratory failure, suggesting the existence of a pulmonary vascular disease progressing independently of the pulmonary parenchymal lesions. The pulmonary artery damage during Takayasu's arteritis and other auto-immune pulmonary arteritis may lead to potentially life-threatening complications, notably through stenosis and/or obstruction of the pulmonary arteries. Pulmonary hypertension is exceptional during Wegener's disease or periateritis nodosa. CONCLUSIONS PH can complicate the progression of certain systemic diseases. The physiopathological mechanisms responsible are unclear (specific parenchymal fibrosis, isolated vascular involvement...). Globally, available treatments are disappointing.

D013625 Takayasu Arteritis A chronic inflammatory process that affects the AORTA and its primary branches, such as the brachiocephalic artery (BRACHIOCEPHALIC TRUNK) and CAROTID ARTERIES. It results in progressive arterial stenosis, occlusion, and aneurysm formation. The pulse in the arm is hard to detect. Patients with aortitis syndrome often exhibit retinopathy.

D014890 Granulomatosis with Polyangiitis A multisystemic disease of a complex genetic background. It is characterized by inflammation of the blood vessels (VASCULITIS) leading to damage in any number of organs. The common features include granulomatous inflammation of the RESPIRATORY TRACT and KIDNEYS. Most patients have measurable autoantibodies (ANTINEUTROPHIL CYTOPLASMIC ANTIBODIES) against MYELOBLASTIN.

D017565 Sarcoidosis, Pulmonary Sarcoidosis affecting predominantly the lungs, the site most frequently involved and most commonly causing morbidity and mortality in sarcoidosis. Pulmonary sarcoidosis is characterized by sharply circumscribed granulomas in the alveolar, bronchial, and vascular walls, composed of tightly packed cells derived from the mononuclear phagocyte system. The clinical symptoms when present are dyspnea upon exertion, nonproductive cough, and wheezing.

D018450 Disease Progression The worsening and general progression of a disease over time. This concept is most often used for chronic and incurable diseases where the stage of the disease is an important determinant of therapy and prognosis.
