Abstract: Objective To analyze the clinical manifestations, imaging and laboratory findings of Takayasu arteritis (TA) patients with history of tuberculosis. Methods The hospitalized patients with TA were divided into two groups according to the history of tuberculosis. The differences of clinical characteristics, imaging and laboratory manifestation were compared. Results Among 103 patients with Takayasu arteritis, 19 had history of tuberculosis, including 15 pulmonary tuberculosis, 2 tuberculous pleurisy, 1 endobronchial tuberculosis and 1 tuberculous peritonitis. There was no significant difference in clinical manifestations and laboratory findings between patients with or without history of tuberculosis. In the patients with history of tuberculosis, numano type V was the most common (63.16%), followed by Ⅱb (15.79%). The proportion of coronary artery involvement, pulmonary artery involvement and cardiac valvular lesion in TA patients with history of TB were 10.53%, 15.79% and 73.68%, respectively. Conclusion The rate of previous tuberculosis infection in patients with Takayasu arteritis is high, but there is no significant difference between the clinical features and those without tuberculosis history.
