目的评价依那西普较柳氮磺吡啶治疗AS前后骨代谢标志物、骨密度、影像学及血清骨保护素/细胞核因子-κB受体活化因子配体(OPG/RANKL)的变化。方法平均随机数字表法将60例AS患者随机分为2组:依那西普治疗组30例和柳氮磺吡啶治疗组27例(脱落3例),疗程均为24周。观察指标包括治疗前后患者BASDAI和急性期反应物水平;血清骨钙素、β-胶原降解产物(CTX)、RANKL及骨保护素的水平;采用双能x线骨密度测量仪测定(DEXA)测定治疗前后腰椎和股骨颈骨密度;并对治疗前后的骶髂关节、髋关节x线影像进行BathAS放射学评分(BASRI)。采用t检验,配对t检验,x2检验进行统计学处理。结果治疗24周后,依那西普组患者外周关节肿痛数(0.7±1.2)、BASDAI[(2.9±1.1)、CRP(1.8±0.9)mg]L]、ESR[(8±4)mm/1h]、CTX[(0.18±0.07)ng/ml]、RANKL[(3.3±2.8)pg/ml]均较治疗前[(3.1±1.4)、(6.5±1.1)、(28±20)mg/L、(55±33)mm/1h、(0.27±0.11)ng/ml、(6.7±2.9)pg/m1]明显下隆(t=3.887,7.642,6.809,7.264,3.639,6.248;P均〈0.05),而骨钙素[(17.1±2.1)ng/ml,(23.1±2.3)ng/m1]、骨保护索[(542±132)pg/ml,(656±82)pg/ml]、OPG/RANKL(142±197,338±229)明显增高(t=3.639,7.159,5.359;P均〈0.05)。柳氮磺吡啶组外周关节肿痛数(0.9±1.2)、CRP[(7.8±3.8)mg/L]、ESR[(28±14)mm/1h]较治疗前明显下降(t=3.092,3.314,3.398;P均〈0.05),而BASDAI、骨钙素、CTX、骨保护素、RANKL、OPG/RANKL较前差异均无统计学意义(P均〉0.05)。治疗24周后,依那西普组较柳氮磺吡啶组BASDAI、CRP、ESR、CTX、RANKL明显下降,骨钙素、骨保护素、OPG/RANKL明显升高(P均〈0.05)。骨密度及影像BASRI评分:60例As患者骨质疏松者10例(17�
Objective To evaluate bone metabolism, bone mineral density, radiology and osteoprote- gerin/receptor activator of nuclear factor-KB ligand (OPG/RANKL) serum levels in patients with ankylosing spondylitis (AS) treated with etanercept compared with sulfasalazine (SSZ). Methods Sixty AS patients were randomly divided into 2 groups: the etanercept group (30 cases) treated with etanercept and SSZ group (27 cases, 3 cases) withdraw treated with SSZ. Serum samples from patients were obtained at baseline and 24 weeks after treatment. Disease activity indexes and serum levels of Osteoealcin (OC), β-collagen degradation products (CTX), RANKL, and OPG were measured before and after treatment respectively. Bone mineral density of lumbar spine and femoral neck were measured by dual energy X-ray and the X-ray images of pelvis were graded based on Bath AS radiology index (BASRI) before and after treatment. Paired t test, t' test, )(2 test were used for statistical analysis. Results After 24 weeks of treatment, the number of swelling and tender joints (0.7±1.2, 3.1±1.4), the Bath AS disease activity index (BASDAI) (2.9±1.1, 6.5±1.1), C reactive protein (CRP) [(1.8±0.9) mg/L, (28±20) mg/L], erythrocyte sedimentation rate (ESR) [(8±4) mrn/1 h, (55±33) mm/1 h], CTX [(0.18±0.07) ng/ml, (0.27±0.11) ng/ml] and RANKL [(3.3±2.8) pg/ml, (6.7±2.9) pg/ml] levels were significantly decreased in the etanercept group (t=3.887, 7.642, 6.809, 7.264, 3.639, 6.248; P 均〈0.05); the serum levels of OC[(23.1±2.3) ng/ml, (17.1±2.1) ng/ml], OPG [(542±132) pg/ml, (656±82) pg/ml] and OPG/RANKL (142±197, 338±229) were significantly increased (t=3.639, 7.159, 5.359; P〈0.05). Number of swelling and tender joints (0.9±1.2, 2.8±1.7), the CRP [(7.8±3.8) mg/L, (21.2±19.2) mg/L] and ESR [(28±4) mm/1 h, (54±33) mm/1 h] were significandy decreased in the suffasalazine group (P〈0.05), but t
