摘要
目的探讨患者总体评价(PGA)在中轴型脊柱关节炎(SpA)患者病情活动性评估中的意义。方法收集222例中轴型SpA患者,分别计算PGA、疾病活动性评分[Bath AS病情活动指标(BASDAI)和基于C反应蛋白计算的强直性脊柱炎疾病活动评价积分(ASDAScrp)]和骶髂关节磁共振扫描下骨髓水肿(SPARCC)积分,比较不同疾病活动度组间PGA的水平,分析PGA与各疾病活动性指标间的相关性。采用SPSS 17.0软件进行统计分析,不同组间率的比较采用χ2检验,不同组间非正态分布计量资料的比较采用秩和检验,两两指标间相关性采用线性相关分析,采用ROC曲线计算PGA对判断中轴型SpA患者病情活动的截点值。结果① BASDAI缓解组PGA中位数[3(1,4)与5(4,7)]和ASDAScrp缓解组PGA中位数[1(1,2)与4(2,5)]明显低于活动组(P均〈0.01)。②BASDAI水平[1.80(1.20,2.90)与3.40(2.28,4.63)与5.15(4.08,5.88)]和ASDAScrp水平[2.19(1.34,2.76)与2.86(2.08,3.54)与4.08(2.96,4.41)]在PGA低度组(≤3)、中度组(4~6)和高度组(≥7)间差异有统计学意义(P均〈0.01);SPARCC积分在PGA低度组[6.00(0,18.00)]、中度组[7.50(3.75,18.00)]和高度组[18.50(6.75,24.50)]间差异有统计学意义(Z=7.427,P=0.037);ESR[12.00(5.00,23.00)mm/1 h,19.50(7.00,44.50)mm/1 h,18.00(7.75,54.75)mm/1 h]、CRP[7.85(2.37,22.49)mg/L,10.07(3.02,28.51)mg/L,21.28(7.14,37.74)mg/L]和BASFI[0.70(0.10,1.30),2.25(0.60,3.30),2.85(0.83,6.53)]等功能指标在PGA低度组、中度组和高度差异有统计学意义(P均〈0.01)。③ BASDAI病情活动组患者在PGA低度组、中度组和高度组所占比例差异有统计学意义(χ2=54.895,P〈0.01),且两者间呈正相关(r=0.497,P〈0.01);ASDAScrp高度以上病情活动组中在PGA低度组、中度组和高度组间所占比例�
ObjectiveTo explore the value of patient global assessment (PGA) on evaluating disease activity in patients with axial spondyloarthritis (SpA).MethodsA total of 222 patients with axial SpA were recruited. Scores of PGA, disease activity index [Bath ankylosing spondylitis disease activity index (BASDAI), ankylosing spondylitis disease activity score (ASDAS)crp] and spondyloarthritis research consortium of Canada (SPARCC) were calculated. Differences of PGA scores between different disease activity groups in axial SpA were compared and correlations between different disease activity index with PGA scores were analyzed. Statistical analyses were performed using Statistical Product and Service Solutions (SPSS) software (version 17.0). Comparison of frequency among different groups was performed by χ2 test. Rank-sum test was used to compare the median of measurement data in different groups when the data were skewed in distribution. Cut-off value of PGA for assessing disease activity in axial SpA was calculated by ROC curve.ResultsMedians of PGA score in groups with BASDAI remission[3(1,4) vs 5(4,7)] and ASDAScrp remission [1(1,2) vs 4(2,5)] were lower than that in disease activity group (P〈0.01). BASDAI scores [1.80(1.20, 2.90) vs 3.40(2.28, 4.63) vs 5.15(4.08, 5.88)] and ASDAScrp scores [2.19(1.34, 2.76) vs 2.86(2.08, 3.54) vs 4.08(2.96, 4.41)] were significant different among PGA groups (≤3, 4-6 and ≥7) (P〈0.01). Differences of SPARCC scores [6.00(0, 18.00) vs 7.50(3.75, 18.00) vs 18.50(6.75, 24.50)] were statistically significant among PGA groups (Z=7.427, P=0.037). Erythrocyte sedimentation rate (ESR) [12.00(5.00, 23.00) mm/1 h vs 19.50(7.00, 44.50) mm/1 h vs 18.00(7.75, 54.75) mm/1 h], C-reactive protein (CRP) [7.85(2.37, 22.49) mg/L vs 10.07(3.02, 28.51) mg/L vs 21.28(7.14, 37.74) mg/L] and Bath ankylosing spondylitis functional index (BASFI) [0.70(0.10, 1.30) vs 2.25�
