强直性脊柱炎合并大动脉炎延误诊断一例并文献复习

目的探讨强直性脊柱炎(ankylosing spondylitis,AS)合并大动脉炎(takayasu arteritis,TA)的临床特点,以减少误诊误治。方法回顾性分析1例AS合并TA患者的临床资料,并复习相关文献。结果 1本例为25岁青年男性,有AS病史5年,在外院诊治过程中先后出现肺部感染、心力衰竭等,给予相应治疗效果欠佳,转我院。经详细查体,发现左侧桡动脉搏动减弱,双上肢血压差较大,颈部及左锁骨下闻及血管杂音,炎性指标升高,结合颈部磁共振动脉造影及全主动脉计算机体层摄影血管成像结果,补充诊断TA。予糖皮质激素联合环磷酰胺治疗,病情明显改善。2在Pub Med、维普科技期刊数据库,以AS+TA为检索式,共命中7篇相关文献累计患者12例,以HLA-B27阳性者居多,均先诊断AS,多年后发现合并TA,炎性指标均升高,均有血管杂音。结论当AS患者出现发热、血管杂音、无脉时,应警惕是否合并TA。AS与TA是否具有遗传易感性尚有待进一步研究。     

强直性脊柱炎患者外周血T细胞受体β链可变区基因谱系多态性的初步研究

目的 探讨强直性脊柱炎(AS)患者外周血T细胞受体β链可变区互补决定区3(TCRBV CDR3)谱系多态性,为AS免疫发病机制研究提供实验依据.方法 采用反转录-聚合酶链反应(RT-PCR)扩增AS患者外周血单个核细胞(PBMC)中T细胞TCR BV的26个亚家族CDR3,经免疫扫描谱型技术分析TCR BV CDR,3的谱系多态性情况.结果 20例活动期AS患者TCR BV CDR3扫描谱型均出现非正态的异常峰型,包括单峰、寡峰/寡峰趋势、偏峰和不规则异常峰型.其中有18例患者部分亚家族出现寡克隆/寡克隆趋势增生,有1例患者BV16和BV18的2个亚家族出现单克隆增生.5名健康对照PBMC TCR BV CDR3谱型绝大多数呈高斯分布.结论 AS患者外周血TCR BV CDR3谱系具有显著多态性和谱系漂移特点,进一步表明T细胞在AS免疫发病机制中扮演重要角色.单/寡克隆增生的T细胞有可能是AS发病中的自身反应性T细胞.     

Dickkopf-1 in ankylosing spondylitis: Relation to spinal dysmobility and radiographic findings

Back groundDickkopf-1 (DKK-1) is an inhibitory molecule that regulates Wnt pathway, which is critically important in osteoblastic new bone formation, therefore it may play a role in the process of new bone formation in Ankylosing Spondylitis (AS).Aim of the workTo measure serum level of DKK-1 in AS patients and study the relation between these levels with disease activity, spinal dysmobility and radiographic findings.Patients and methodsThirty AS patients as well as 20 healthy subjects as a control group were included in this study. DKK-1 serum levels were measured using ELISA technique, disease activity was assessed using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, radiographic assessment by Bath Ankylosing Spondylitis Radiology Index-spine (BASRI-s) and modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS).ResultsDKK-1 was not correlated to ESR, CRP or BASDAI (p > 0.05) and was negatively correlated to BASRI-s and mSASSS (p < 0.001), though DKK-1 serum level was unexpectedly higher in patients versus control (p < 0.001). On comparing HLA-B27 positive and HLA-B27 negative patients, there were a significant increase in BASRI-s and mSASSS and decrease in DKK-1 level in those with positive HLA-B27 (p < 0.05). On comparing patients received anti TNF therapy and those not received anti TNF therapy, there was no significant difference in DKK-1 level (p > 0.05).ConclusionOur finding suggests dysfunction of DKK-1 in patient with AS.     

Cost-of-Illness and Quality of Life in Patients with Ankylosing Spondylitis at a Tertiary Hospital in Korea

The objectives of this study were to estimate the cost-of-illness (COI) and health-related quality of life (HRQOL) in patients with ankylosing spondylitis (AS) in Korea and to evaluate the effects of socio-demographic and clinical factors on the COI and the HRQOL. Face-to-face interview surveys were taken from patients with AS at the Rheumatology Clinic of Seoul National University Hospital. Direct medical and non-medical costs, indirect costs (productivity loss due to job loss and sick leave), and deterioration of HRQOL in patients with AS were measured. Factors associated with COI and HRQOL were analyzed with multiple regression and multivariate logistic regression. A total of 191 patients with AS was enrolled in the study. The COI in patients with AS amounted to 11,646,180 Korean Won (KRW) per patient, and their HRQOL was 0.62. As functional severity worsened, the total costs increased (class I, KRW 7.7 million; class II, KRW 12.9 million; classes III & IV, KRW 25.2 million) and the HRQOL scores decreased (class I, 0.72; class II, 0.61; classes III & IV, 0.24). Functional severity is the major determinant of the COI and HRQOL in patients with AS.

The Reliability and Validity of a Korean Translation of the ASAS Health Index and Environmental Factors in Korean Patients with Axial Spondyloarthritis

The objective of this study was to develop a Korean version of the Assessment of Spondyloarthritis International Society-Health Index/Environmental Factor (ASAS HI/EF) and to evaluate its reliability and validity in Korean patients with axial spondyloarthritis (SpA). A total of 43 patients participated. Translation and cross-cultural adaptation of the ASAS HI/EF was performed according to international standardized guidelines. We also evaluated validity by calculating correlation coefficients between the ASAS-HI/EF score and the clinical parameters. Test-retest reliability was excellent. The correlations among the mean ASAS-HI score and all tools of assessment for SpA were significant. When it came to construct validity, the ASAS HI score was correlated with nocturnal back pain, spinal pain, patients''s global assessment score, the Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis metrology index (BASMI) and EuroQoL visual analogue scale (EQ VAS) (r = 0.353, 0.585, 0.598, 0.637, 0.690, 0.430, and -0.534). The ASAS EF score was also correlated with the patient''s global assessment''s score, BASDAI, BASFI, BASMI, and EQ VAS score (r = 0.375, 0.490, 0.684, 0.485, and -0.554). The Korean version of the ASAS HI/EF can be used in the clinical field to assess and evaluate the state of health of Korean axial SpA patients.

Follow-up Testing of Interferon-Gamma Release Assays Are Useful in Ankylosing Spondylitis Patients Receiving Anti-Tumor Necrosis Factor Alpha for Latent Tuberculosis Infection

We evaluated the utility of follow-up interferon-gamma release assays (IGRAs) for the diagnosis of reactivation of latent tuberculosis infection (LTBI) or new tuberculosis in ankylosing spondylitis (AS) patients receiving anti-tumor necrosis factor alpha (anti-TNFα). The study participants (n=127) had a negative IGRA screening before receiving anti-TNFα and were evaluated by follow-up IGRA. We retrospectively examined data of the subjects according to age, gender, tuberculosis prophylaxis, concomitant medications, IGRA conversion and anti-TNFα, including type and treatment duration. The median duration of anti-TNFα was 21.5 months, and the median age was 35.3 yr. Of the 127 patients, IGRA conversion was found in 10 patients (7.9%). There was no significant variation between IGRA conversion rate and any risk factors except for age. IGRA conversion rate was not significantly different between AS and rheumatoid arthritis (P=0.12). IGRA conversion was observed in AS patients receiving anti-TNFα in Korea. A follow-up IGRA test can be helpful for identifying LTBI or new tuberculosis in AS patients receiving anti-TNFα.
