系统性硬化症的肺部表现

目的分析系统性硬化症（SSc）患者的肺部受累特点及与功能性指标的相关性。方法前瞻性序贯入组68例SSc患者。所有患者完成病史采集和查体,胸部高分辨CT（HRCT）,肺功能[用力肺活量（FVC）、肺总量（TLC）、肺一氧化碳弥散量（DLCO）],6分钟步行试验,以及心脏彩色多普勒检查。其中36例完成圣乔治呼吸问卷（SGRQ）。结果 HRCT发现52例（76.5%）SSc患者存在间质性肺病（SSc-ILD）,其中20例（38.5%）无呼吸道症状。最常见的HRCT表现为网格影（80.8%）、磨玻璃影（73.1%）、牵拉性支气管扩张（59.6%）和蜂窝肺（30.8%）。SSc-ILD患者中有30例（57.7%）以纤维化（网格影、蜂窝肺和牵拉性支气管扩张）为主要表现,单纯磨玻璃影仅见于8例（15.7%）。57例（83.8%）SSc患者存在弥散功能障碍,FVC和TLC下降见于28例（41.2%）和20例（29.4%）患者。肺功能指标中,DLCO与HRCT间质病变范围相关性最显著（rs=-0.476,P=0.000）,并且与4项SGRQ评分均显著负相关（r=-0.392~-0.595,P〈0.05）。多因素分析显示DLCO、SpO2和Borg指数是SGRQ评分的主要影响因素。结论中国SSc患者肺部受累常见且起病隐匿,诊断时HRCT表现以纤维化为主合并磨玻璃影,有必要对SSc患者进行胸部HRCT筛查。SSc肺功能损害的主要特点为弥散障碍,DLCO对于早期发现SSc-ILD以及评价严重程度具有重要价值。SGRQ可用于评价SSc患者的健康相关生活质量,并且反映了肺部受累的严重程度。     

抗U1核糖核蛋白抗体在系统性硬化症诊治中的临床意义

目的探讨抗U1核糖核蛋白（U1RNP）抗体在系统性硬化症（SSc）诊治中的价值。方法前瞻性序贯纳入在北京协和医院入选欧洲抗风湿病联盟硬皮病试验研究组（EUSTAR）的131例中国汉族SSc患者,记录其临床表现、脏器损伤和实验室检查结果（包括抗U1RNP抗体的检测结果）,分析抗U1RNP抗体阳性组与阴性组临床特征及实验室指标的特点。结果131例SSc患者中含87例弥漫型SSc、36例局限型SSc、8例重叠综合征,抗U1RNP抗体阳性率为28．2％（37／131）。弥漫型SSc和局限型SSc的抗U1RNP抗体阳性率相近,分别为28．7％（25／87）和25．0％（9／36）,P=0．673。抗U1RNP抗体阳性者较阴性者易重叠系统性红斑狼疮,肺动脉高压和心脏受累发生率增加,白细胞和血小板计数减低（均P〈0．05）;而在皮肤硬化评分及关节炎、肌炎、肺间质病变发牛率上差异无统计学意义（均P〉0．05）。抗U1RNP抗体阴性的SSc有更高的抗DNA拓扑异构酶Ⅰ抗体检出率。结论抗U1RNP抗体是中国SSc患者的常见自身抗体,与其他自身抗体联合检测有助于SSc的诊断,对预测肺动脉高压、心脏和血液系统受累有重要价值。

中国系统性硬化症患者硬皮病相关自身抗体的检测及其临床意义

目的 检测中国系统性硬化症(SSc)患者血清中硬皮病相关自身抗体-抗Sol-70抗体、抗着丝点抗体(ACA)和抗RNA多聚酶Ⅲ抗体(ARA),分析其与各种临床表现之间的关系.方法 序贯纳人入选欧洲抗风湿病联盟硬皮病实验研究组(EULAR Scleroderma Trial and Research Group,EUSTAR)的135例巾国SSc患者,分别用线性免疫印迹法、免疫双扩散法和间接免疫荧光法检测ARA、抗Scl-70抗体、ACA在患者血清中表达水平,并进一步分析自身抗体与患者各种临床表现之间的相关性.结果 在135例SSc患者中抗Sel-70、ACA、ARA的阳性率分别为49 6%、13 3%和8.9%.抗Scl-70抗体阳性组患者的病程显著短于阴性组[(71±59)个月vs(90±103)个月,P=0 041],肺问质病变的患病率亦显著高于阴性组(P=0.031),但阳性组肺动脉高压的患病率显著低于阴性组(P=0 042),修订的Rodnan皮肤硬化评分(P=0 008)、面颈部皮肤硬化(P=0.002)、肘/膝关节远端皮肤硬化(P=0.004)以及指端凹陷性瘢痕/指垫消失的发生率(P=0.01)均显著高于阴性组;ACA附性组患者的病程长于阴性组,差异具有统计学意义[(90±107)个月vs(69±64)个月,P=0.036],肺间质病变的患病率显著低于阴性组(P=0 045),IgM水平亦显著低于阴性组(P=0 045);ARA阳性组和阴性组患者的病程等各项临床指标差异均无统计学意义,但阳性组血清肌酐和尿素氨水平显著高于阴性组(P＜0.001).ACA和ARA患者各项皮肤硬化指标在阳性组和阴性组差异均尤统计学意义.结论 硬皮病特异相关的自身抗体与不同的临床表现紧密相关,检测此类抗体可能有助于SSc的诊断、脏器受累和预后评估.这些自身抗体在中国SSc患者的临床相关性可能不同于其他地区的SSc患者.

Abstract：

Objective To detect the expression of scleroderma-related autoantibodies, such as anti-Scl-70, anli-centromere antibody ( ACA)and anti-RNA polymerase Ⅲ ( ARA) , and their relationship with clinical features in Chinese systemic sclerosis (SSc) patients. Methods One hundred and thirty-five Chinese SSc patients from the clinical database of the Scleroderma Trials and Research Group proposed by European League Against Rheumatism's Scheroderma Trial and Research Group( EUSTAR) were consecutively enrolled. The expression of ARA, anti-Scl-70 and ACA were detected through linear immunoblotting, double immunodiffusion and indirect irnmunofluorescence, respectively. The relevance between the existing of autoantibodies and clinical manifestations was analyzed statistically. Results Among the 135 Chinese SSc patients, the prevalence of anti-Scl-70, ACA, ARA were 49. 6% , 13.3 % and 8.9% respectively. Patients with anti-Scl-70 antibody had significantly shorter disease course [(71 ±59) month vs (90 ± 103) month, P = 0.041] , higher proportion of interstitial lung disease ( P = 0. 031) but lower of pulmonary arterial hypertension (P =0.042). Modified Rodnan's skin score (P=0.008) and prevalence of facial and cervical cutaneous sclerosis (P = 0. 002) , distal (to elbow/knee ) cutaneous sclerosis ( P = 0. 004 ) and digital pitting scarring/disappear of digital pad were all significantly higher in anti-Scl-70 positive group. Patients with AC A had longer disease course ( P = 0. 036) , lower IgM level ( P = 0. 045) and were less prevalent of interstitial lung disease ( P =0. 045). Patients with ARA had higher serum creatinine and urea nitrogen level ( P ＜ 0.001) although otherwise features had unremarkable differences. Conclusion Scleroderma-related autoantibodies have relevance with different clinical manifestation and detection of these autoantibodies may be helpful to the diagnosis of SSc, organ involvement evaluation and predicting outcomes. The clinical relevances of autoantibodies in Chinese SSc patients may differ from other areas or races.

系统性硬化病患者临床表现分析:来自中国欧洲抗风湿病联盟硬皮病试验研究组数据库资料

目的 探讨中国系统性硬化病(SSc)患者脏器受累的情况,以了解中国SSc患者的临床特点.方法 北京协和医院欧洲抗风湿病联盟硬皮病试验研究组(EUSTAR)数据库中,在2009年2月至2010年1月间前瞻性收集了SSc患者共119例,均满足1980年美国风湿病学会(ACR)SSc分类(诊断)标准.对其临床表现、实验室检查进行分析.采用x2检验和独立样本t检验.结果 (1)流行病学方面:女性109例,男性10例,平均年龄(44±12)岁,从雷诺现象到出现脏器受累的中位病程12个月,其中弥漫性SSc 65例.112例患者(94.1%)有雷诺现象,雷诺现象的起病中位年龄36岁.其中91例患者以雷诺现象为首发表现.(2)临床表现方面:①以消化系统(70.6%),尤其是食管受累(56.3%),关节受累(54.6%)以及肺间质纤维化(PIF)(58.8%)最为常见,但肾危象(2.5%)、心脏传导阻滞(0)以及左室射血分数减低(0)很少见.②70例PIF中加例(29%)无呼吸系统的临床症状,为常规筛查时发现;65例在雷诺现象后3～352个月出现,中位时间34个月;24例肺动脉高压(PAH)中3例无临床症状;22例在雷诺现象后4～343个月出现,中位时间25个月;19例患者同时有PIF和PAH.③外周血管:肱踝指数水平显著降低(0.91±0.19与1.09±0.08,t=-2.288,P<0.01).(3)实验室检查:抗核抗体检查均为阳性;抗Scl-70抗体和抗着丝点抗体(ACA)阳性率分别为56.0%和14.7%,未见ACA及Scl-70同时阳性者;13%的患者RNA多聚酶Ⅲ抗体阳性.(4)弥漫性硬皮病(dcSSc)和局限性硬皮病(IcSSc)患者在脏器受累和实验室检查间的比较结果显示,dcSSc较IcSSc患者指溃疡(40%与20%)更多见,ACA抗体少见(4/52与10/43,P<0.05).结论 SSc皮肤外脏器受累并不少见,尤其是肺间质病变和消化系统受累.在中国患者中,肾危象及心脏传导阻滞明显减少.由于部分肺间质病变患者并无临床表现,因此早期进行筛查是早期诊断及治疗的关键.

Abstract：

Objective To investigate the clinical and laboratory characteristics of SSc patients in China. Method The data of 119 consecutive SSc patients based on EUSTAR DATABASE in Peking Union Medical College Hospital from February 2009 to January 2010 were prospectively collected and analyzed. All patients fulfilled ACR classification criteria in 1980 for SSc. Thex2 test and t-test were used to analyze the data. Results (1) Demographic data. Sex ratio (F/M) was 109/10 and the age rang was (44±12) years. There were 65 diffuse cutaneous SSc (dcSSc) patients and 54 limited cutaneous SSc (1cSSc) patients. 112 patients (94.1%) had Raynaud's phenomenon (RP), and the age of RP occurrence was 36 years (13～76 years), among which it was the initial presentation in 91 patients (81.3%) and the disease duration from RP to other manifestation was 12 months. (2) Clinical manifestations. ① The gastrointestinal manifestations (70.6%), especially esophageal involvement (56.3%), articular involvement (54.6%), pulmonary interstitial fibrosis (PIF) (58.8%) were frequently observed, but renal crisis (2.5%), heart block (0) and reduced LVEF (0) were rarely detected. ② Twenty cases (28.6%) out of 70 PIF patients denied any respiratory symptom and were confirmed by HRCT screening. The disease duration from RP to PIF was 34 months(3～352months); 3 case of 24 pulmonary artery hypertension (PAH) patients had no clinical manifestations. The disease duration from RP to PAH was 25 months (4～343 months). Nineteen patients had PIF and PAH simultaneously. ③Peripheral artery disease: SSc patients had a lower ankle brachial index (ABI) level (0.91± 0.19 vs 1.09±0.08, P<0.00l). (3) Laboratory finding. All patients had positive ANA. The positive rate of anti-Scl-70 antibody and ACA was 56.0% and 14.7% respectively. There was no serum sample positive for anti-Scl-70 antibody and ACA. The positive rate of anti-RNA polymerase Ⅲ antibody was 13%. (4) Compared the clinical characteristics and laboratory findings between dcSSc and lcSSc patients, we found that there were significant differences between dcSSc and lcSSc patients in finger ulcer (40.0% vs 20.4%), ACA positive rates (7.7% vs 23.3% , P<0.05). Conclusion The system involvements besides skin in SSc is common, especially PIF and gastrointestinal involvement. According to our data, there are fewer cases with renal crisis and heart block. Because part of patients with PIF have almost no clinical manifestations, so early screening for PIF/PAH is important for early diagnosis and intervention.     

系统性红斑狼疮病情评估体系解读

系统性红斑狼疮(systemic lupus erythematosus,SLE)是一种累及多器官系统的自身免疫性疾病.SLE临床表现多样:既可有单纯的皮肤黏膜损伤,又可合并肾脏等重要脏器损伤;严重程度不一:既可是轻微隐匿的,也可是严重而致命的;同时SLE病情有自发缓解和加重的波动过程.导致SLE表型复杂的原因不仅与疾病本身相关,还会受到并发症及药物不良反应等因素的影响.
