This study compared the sensitivity of the Expanded Disability Status Scale (EDSS) and the Multiple Sclerosis Functional Composite (MSFC) as clinical endpoints in multiple sclerosis (MS) clinical trials.
Medline (1946 through 12 September 2014) and Embase (1974 through 12 September 2014) databases searches were conducted using keywords and Medical Subject Heading (MeSH) terms related to MS, EDSS, and MSFC. Only studies that used the EDSS and MSFC as endpoints were assessed. All statistical analyses were conducted using comprehensive meta-analysis (CMA). The percentages of the overall changes in EDSS and MSFC were compared. The relative risks were calculated in randomized clinical trials (RCTs).
A total of 123 studies were identified. There were nine studies (6 case series and 3 RCTs) included in the analysis. In the case series, the EDSS change rate in MS patients was 33.5% (95% CI: 12.9-63.2%) and the MSFC change rate was 30.3% (95% CI: 9.2-65.2%). In RCTs, patients who take the drug would be 22.9 times as likely as patients who did not take the drug to experience a change in the EDSS scale (RR = 22.9, 95% CI = 0.996-1.517, p = 0.055). Patients who take the drug would be 48.9 times as likely as patients who did not take the drug to experience a change in the MSFC scale (RR = 48.9, 95% CI = CI = 0.916-2.419, p = 0.108).
This study focused only on MS patient improvement (positive changes) on the EDSS and MSFC. More studies are needed to include patient deterioration (negative changes) on EDSS and MSFC.
There is controversy about the sensitivity of the EDSS and MSFC in detecting the progression of MS disease. The EDSS and MSFC are effective tools to assess the clinical severity and progression of MS disease. MSFC is more sensitive than EDSS in detecting the progression of MS disease.
本研究比较了扩展残疾状态量表(EDSS)和多发性硬化功能综合评分(MSFC)作为多发性硬化症(MS)临床试验临床终点的敏感性。
使用与MS、EDSS和MSFC相关的关键词和医学主题词(MeSH)检索Medline(1946年至2014年9月12日)和Embase(1974年至2014年9月12日)数据库。仅评估将EDSS和MSFC用作终点的研究。所有统计分析均使用综合荟萃分析(CMA)进行。比较了EDSS和MSFC总体变化的百分比。在随机临床试验(RCT)中计算相对风险。
共识别出123项研究。分析纳入了9项研究(6项病例系列研究和3项RCT)。在病例系列研究中,MS患者的EDSS变化率为33.5%(95%CI:12.9 - 63.2%),MSFC变化率为30.3%(95%CI:9.2 - 65.2%)。在RCT中,服用药物的患者EDSS量表出现变化的可能性是未服用药物患者的22.9倍(RR = 22.9,95%CI = 0.996 - 1.517,p = 0.055)。服用药物的患者MSFC量表出现变化的可能性是未服用药物患者的48.9倍(RR = 48.9,95%CI = CI = 0.916 - 2.419,p = 0.108)。
本研究仅关注MS患者在EDSS和MSFC上的改善(正向变化)。需要更多研究纳入患者在EDSS和MSFC上的恶化(负向变化)情况。
关于EDSS和MSFC在检测MS疾病进展方面的敏感性存在争议。EDSS和MSFC是评估MS疾病临床严重程度和进展的有效工具。在检测MS疾病进展方面,MSFC比EDSS更敏感。
