ABSTRACT
To assess the effectiveness of cyclophosphamide (CYC) versus methotrexate (MTX) for active Takayasu's arteritis (TA). The current study was based on a cohort of TA at Zhongshan Hospital, Fudan University. TA was diagnosed using the 1990 American College of Rheumatology criteria. Fifty-eight subjects receiving induction treatment with CYC (n = 46) or MTX (N = 12) were included in the analysis. Effectiveness and toxicity were assessed in all 58 cases. Clinical remission was defined as Kerr score reduction to ≤ 1 and glucocorticoids (GC) treatment at a dose of ≤ 0.2 mg/kg/day (≤ 15 mg/day) at the end of the 6th month. At the baseline, the CYC group had higher Kerr scores (60.9% vs. 16.7% at ≥3, p = 0.044), higher ESR (55 ± 52 vs. 25 ± 22 mm/H, p = 0.048), ITAS_ESR (12.4 ± 1.7 vs. 9.1 ± 1.1 mg/L, p = 0.043). The 6-month clinical remission rate was 71.7% vs. 75% in the CYC and MTX group, respectively. In the CYC group, a significant decrease was observed in ESR (55 ± 52 vs. 25 ± 48 mm/H, p = 0.008), hs-CRP (27 ± 23 vs. 6.9 ± 6.6 mg/L, p = 0.007), ITAS (11.7 ± 2.2 vs. 7.0 ± 1.5, p = 0.048), and ITAS_ESR (7.1 ± 2.0 vs. 12.4 ± 1.7, p = 0.033). However, no significant reductions in these measures were demonstrated in the MTX group. Whole-body contrast enhanced magnetic resonance angiography (MRA) revealed significant radiologic improvement (wall enhancement scores 4.2 ± 2.3 vs. 10.3 ± 3.8, p = 0.032) in the CYC group, but not in the MTX group. No severe adverse events occurred in any subject. Cyclophosphamide could be a better choice than methotrexate as induction treatment for patients with more severe Takayasu's arteritis.
