          Abstract

          Takayasu arteritis is a chronic granulomatous disease of the aorta and its major branches that usually affects women during the second and third decades of life, but it has been reported in young children. This review details the clinical, pathological and radiological features, differential diagnoses and management of the condition, focusing chiefly on the disease in children. The recent definition of Takayasu arteritis is discussed. The condition should be considered in patients with unexplained arterial hypertension or unexplained inflammatory syndromes without signs of localization. Since the disease may be life-threatening and progressive, early recognition is necessary to initiate appropriate therapy. Patients with persistent ischaemic symptoms including hypertension might benefit from revascularization procedures.

          The American College of Rheumatology 1990 criteria for the classification of Takayasu arteritis.

          Criteria for the classification of Takayasu arteritis were developed by comparing 63 patients who had this disease with 744 control patients with other forms of vasculitis. Six criteria were selected for the traditional format classification: onset at age less than or equal to 40 years, claudication of an extremity, decreased brachial artery pulse, greater than 10 mm Hg difference in systolic blood pressure between arms, a bruit over the subclavian arteries or the aorta, and arteriographic evidence of narrowing or occlusion of the entire aorta, its primary branches, or large arteries in the proximal upper or lower extremities. The presence of 3 or more of these 6 criteria demonstrated a sensitivity of 90.5% and a specificity of 97.8%. A classification tree also was constructed with 5 of these 6 criteria, omitting claudication of an extremity. The classification tree demonstrated a sensitivity of 92.1% and a specificity of 97.0%.

            Takayasu arteritis.

            To evaluate prospectively the clinical features, angiographic findings, and response to treatment of patients with Takayasu arteritis. 60 patients with Takayasu arteritis were studied at the National Institute of Allergy and Infectious Diseases between 1970 and 1990 and were followed for 6 months to 20 years (median follow-up, 5.3 years). Data on clinical features, angiographic and laboratory findings, disease course, and response to therapy were all recorded and stored in a computer-based retrieval system. The Warren Magnuson Clinical Center of the National Institutes of Health. In our series of patients, Takayasu arteritis was more common in Asian persons compared with persons from other racial groups. Females (97%) were most frequently affected. The median age at disease onset was 25 years. Juveniles had a delay in diagnosis that was about four times that of adults. The clinical presentation ranged from asymptomatic to catastrophic with stroke. The most common clinical finding was a bruit. Hypertension was most often associated with renal artery stenosis. Only 33% of all patients had systemic symptoms on presentation. Sixty-eight percent of patients had extensive vascular disease; stenotic lesions were 3.6-fold more common than were aneurysms (98% compared with 27%). The erythrocyte sedimentation rate was not a consistently reliable surrogate marker of disease activity. Surgical bypass biopsy specimens from clinically inactive patients showed histologically active disease in 44% of patients. Although clinically significant palliation usually occurred after angioplasty or bypass of severely stenotic vessels, restenosis was common. Medical therapy was required for 80% of patients, whereas 20% had monophasic self-limiting disease. Immunosuppressive treatment with glucocorticoids alone or in combination with a cytotoxic agent failed to induce remission in one fourth of patients; about half of those who achieved remission later relapsed. In North America, Takayasu arteritis is a rare disease. It is heterogeneous in presentation, progression, and response to therapy. Current laboratory markers of disease activity are insufficiently reliable to guide management. Most patients require repeated and, at times, prolonged courses of therapy. Although mortality was low, substantial morbidity occurred in most patients.

              Angiographic findings of Takayasu arteritis: new classification.

              Having proposed a new classification on angiographic findings of patients with Takayasu arteritis, we evaluated the angiographic findings of 80 Japanese patients and 102 Indian patients according to this classification. Japanese patients showed a higher frequency of involvement of the ascending aorta, aortic arch and its branches than did the Indians (P < 0.01). On the other hand, the frequency of involvement of the abdominal aorta and/or renal arteries was higher in Indian patients (P < 0.01). Type III cases of the new classification which involves the thoracic descending aorta, abdominal aorta and/or renal arteries were observed in 3% of the Indian patients, but not at all in the Japanese. In conclusion, in Japanese patients, vascular lesions tend to occur primarily in the ascending aorta, aortic arch and/or its branches and extend into the abdominal aorta. On the other hand, in Indian patients, the tendency is primarily in the abdominal aorta including renal arteries and extending into the thoracic aorta.
