Pulmonary manifestations of connective tissue disease include both vascular and interstitial involvement. While the evaluation of dyspnea in connective tissue disease is essentially the same as in an otherwise healthy dyspneic patient, there are certain autoimmune diseases in which routine screening for interstitial or pulmonary vascular disease is warranted by a high incidence of these complications. In particular, systemic sclerosis and mixed connective tissue disease are so often complicated by interstitial lung disease (in our study ILD; approximately 24 of patients with MCTD and allmost of whole group with SS-96%).

Manifestările pulmonare din maladiile autoimune ale țesutului conjunctiv includ implicările vasculare și intersițiale. Evaluarea dispneei este primordială din cadrul bolilor difuse ale ţesutului conjunctiv din cauza riscului crescut al acestor complicaţii. Un deosebit interes, îl are BMȚC (boala mixtă a țesutului conjunctiv) și sclerodermia sistemică (SS) care se complică frecvent cu boala interstițială pulmonară (în studiul nostru, pneumofibroza interstițială difuză a alcatuit 24% pentru bolnavii cu BMȚC comparativ cu lotul SS – 96%).
