Ecografía clínica en las enfermedades autoinmunes sistémicas

Abstract

Clinical ultrasonography should be considered a complementary examination that can change clinical practice, as well as a tool to add to the medical history.Systemic autoimmune diseases (SAD) can involve numerous structures and organs. Ultrasonography has broad applied utility in detecting complications such as the presence of free intraabdominal, pleural and pericardial fluid in polyserositis, left ventricular systolic dysfunction in myocarditis and deep vein thrombosis in antiphospholipid syndrome.Specifically for SAD, ultrasonography helps examine the salivary glands in Sjögren's syndrome, determines the presence of the halo sign in giant cell arteritis and the presence of tendon or joint inflammation, quantifies pulmonary hypertension in scleroderma and assesses the presence of interstitial pulmonary disease in dermatomyositis.Clinical ultrasonography performed by internists is therefore an extremely useful technique in the diagnosis and follow-up of patients with SAD.
