目的 了解未分化脊柱关节病 ( undifferentiated spondyloarthropathies,u Sp As)的发病情况及临床特点。方法 收集 1年内就诊于我院风湿性疾病门诊的 147例血清阴性脊柱关节病患者 ,对其中 116例 u Sp As患者进行临床分析。结果 本组 u Sp As患者女性比例较强直性脊柱炎( AS)组高 ,临床症状较轻 ,均无腰椎活动受限 ;HL A- B2 7阳性率低于 AS组 ;不一定有骶髂关节炎。 84 .5% u Sp As患者符合 Amor标准 ,85.3%符合欧洲脊柱关节病研究组 ( ESSG)标准。结论 u Sp As是门诊中很常见的血清阴性脊柱关节病 ,误诊率较高 ,本文推荐用 Amor和 ESSG标准进行诊断
Objective To investigate the incidence and clinical characteristics of undifferentiated spondyloarthropathies (u Sp As). Methods One hundred and seventy-seven patients with seronegative spondyloarthropathies who were diagnosed with rheumatic diseases in our hospital within one year were enrolled in this study. One hundred and sixteen patients with u Sp As were enrolled in this study. Results The patients with u Sp As in this group had higher proportion of female patients with AS, lower clinical symptoms, no limitation of lumbar activity, the positive rate of HL-B2 7 was lower than that of AS patients, and the sacroiliac joint inflammation. 84.5% u Sp As patients met the Amor criteria, 85.3% meet the European Spine Arthropathy Study Group (ESSG) standards. Conclusion u Sp As is a common out-patient seronegative spondyloarthropathy, misdiagnosis rate is high, this paper recommends the use of Amor and ESSG criteria for diagnosis
