Title: Vasculitis Poster III: Immunosuppressive Therapy in Giant Cell Arteritis and Polymyalgia Rheumatica
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Aortic valve (AV) surgery is often performed for aortic regurgitation (AR) in patients with Takayasu arteritis (TA). However, data on the long-term outcomes, including survival and cardiac and cerebrovascular outcome, are lacking. This study aimed to characterize the long-term outcomes and prognostic factors of TA patients who underwent surgery for AR.
Methods: Medical records of patients with TA who underwent surgery for moderate to severe AR between January 1995 and December 2015 were reviewed. Poor outcomes were defined as all-cause death and major adverse cardiac and cerebrovascular events (MACCE) including life-threatening aortic aneurysm. Overall survival (OS) was presented with the Kaplan-Meier method and risk factors for poor outcome were analyzed with multivariate Cox analysis.
Results: Total 35 patients with TA with AR underwent AV surgery. The mean age of the patients (male 5, female 30) was 47.2±13 years and the mean follow-up duration was 107.9±85.7 months (median, 97 months; interquartile range, 44-150). Inflammatory values (ESR 36.9±30.6mm/h, CRP 3.4±4.9mg/dL) were elevated and 25 of total 35 patients (71%) received perioperative steroid therapy. The 5-year OS rate of the patients was 85.4% and the 5-year MACCE free survival rate was 73.9% (OS rate; 68.1%, MACCE free survival; 46.6% at 10-year). Eighteen of 35 patients (51.4%) had a poor outcome during follow-up. Re-operation was needed in eleven patients (11/35, 31.4%) and stroke occurred in three patients (3/35, 8.6%). Hata angiographic classification type V (6/17 [35.3%] vs 10/18 [55.6%], p = 0.036) and coronary disease (0/17 [0%] vs 4/18[22.2%], p=0.030) were significantly more frequent in patients with poor outcome. Multivariate analysis revealed that coronary disease (hazard ratio [HR], 4.665; 95% confidence interval [CI], 1.252-17.385; p = 0.022), diagnosis of TA before the age of 40 (HR, 3.909; 95% CI, 1.221-12.517; p = 0.022) were significantly associated with development of poor outcomes (Table 1).
Conclusion: In patients with TA with surgery for AR, poor cardiovascular outcome was frequently observed during follow-up period. It was associated with concomitant coronary artery disease, and TA diagnosis before the age of 40.

| Variables | HR | 95% CI | p-value |
| Coronary disease¶ | 4.665 | 1.252-17.385 | 0.022 |
| Age at diagnosis of TA < 40 years | 3.909 | 1.221-12.517 | 0.022 |
CI: confidence interval; HR: hazard ratio; TA: Takayasu arteritis
¶coronary disease: severity is more than moderate stenosis (minimal: 1-24%, mild: 25-49% moderate: 50-69%, severe> 70%)
