Gastroenterology:罗马III诊断功能性消化不良现状

2014-02-25 august_love cmt

消化不良是上消化道的一个症候群。在社区中,消化不良的患病率在5%到40%之间。消化不良不仅影响患者生活质量而且增加社会医疗开支。如果能通过症状区分出器质性消化不良和功能性消化不良,那么在消化不良方面的医疗开支可能会降低。尽管7年前就确定了用于诊断功能性消化不良的罗马 III 标准,但是该标准的有效性尚未在严格实施的研究中得到确认。 英国利兹市胃肠病学院的Alexander C Ford博

消化不良是上消化道的一个症候群。在社区中,消化不良的患病率在5%到40%之间。消化不良不仅影响患者生活质量而且增加社会医疗开支。如果能通过症状区分出器质性消化不良和功能性消化不良,那么在消化不良方面的医疗开支可能会降低。尽管7年前就确定了用于诊断功能性消化不良的罗马 III 标准,但是该标准的有效性尚未在严格实施的研究中得到确认。

英国利兹市胃肠病学院的Alexander C Ford博士等开展了一项诊断性试验,表明罗马 III 标准在诊断功能性消化不良方面并不优于旧定义,文章于2014年1月11日在线发表在Gastroenterology上。

该项诊断性试验在2008年1月至2012年12月就诊于加拿大安大略省汉密尔顿市两所医院的胃肠病门诊病人中进行,试验未经选择地纳入连续的大于16岁的新患者。除了排除不认识书面英语的患者,没有其它排除标准。最终获得并分析了1452名有胃肠道症状的连续的成年患者的全部症状、上消化道内镜检查数据和组织学数据。

上消化道内镜检查正常及活检样本的组织病理学无异常发现的患者被归为无器质性胃肠道疾病。功能性消化不良的参考标准为:有上腹痛、上腹烧灼感、餐后饱胀和早饱症状的任一种或多种,且上消化道内镜或组织学活检(如果可获得)未发现可以解释这些症状的的器质性上消化道病变。

上腹痛综合征的参考标准为:有任意程度的上腹痛或上腹灼热感,且上消化道内镜检查未发现器质性的上消化道病变,组织学活检(如果可获得)结果正常。餐后不适综合征的参考标准为:有任意程度的餐后饱胀或早饱且上消化道内镜或组织学活检(如果可获得)未发现可以解释这些症状的器质性疾病。

以参考标准为金标准,分别计算了罗马III标准和罗马Ⅱ标准在诊断功能性消化不良上的敏感度、特异度、阳性似然比、阴性似然比、受试者工作特征曲线下面积和95%的可信区间。

结果显示:在1452名患者中,722名(49.7%)符合罗马 III 标准定义的功能性消化不良,在这些符合罗马 III 标准的患者中,有170名(23.5%)内镜下发现器质性胃肠道疾病。罗马 III 标准诊断功能性消化不良的敏感度为60.7%,特异度为68.7%,阳性似然比为1.94 (95% CI,1.69–2.22),阴性似然比为0.57 (95% CI, 0.52–0.63)。

与之形成对比的是,罗马Ⅱ标准诊断功能性消化不良的敏感度为71.4%,特异度为55.6%,阳性似然比为1.61 (95% CI, 1.45–1.78),阴性似然比为0.51(95% CI, 0.45–0.58)。这两种诊断标准中的ROC曲线下面积无显著差异。

研究得出结论,在含有1452名有胃肠道症状的患者的效度研究中,罗马 III 标准在诊断功能性消化不良方面表现一般,并不显著优于旧定义。

从该项研究来看,现有的功能性消化不良的诊断标准的诊断效度一般,同时也突出了一个事实:尽管为更好地区分功能性消化不良和器质性消化不良做了不断的努力,但尚未得出一种确切有效的诊断方法,也可能要从根本上质疑罗马标准的合理性,未来可能需要一种全新的方法来诊断功能性消化不良。

Gut:肠道屏障受损是功能性消化不良的病生理机制

  功能性消化不良(FD)是一种极其常见的功能性胃肠道疾病,我们对其病生理知之甚少。研究者推测肠道屏障功能损害通过诱导轻度炎症而参与了该疾病的起病和维持。因此,来自比利时的一项研究评价了FD患者的十二指肠黏膜完整性和轻度炎症。该研究结果对FD患者胃肠道不存在结构改变的经典认识提出了挑战。研究者认为肠道屏障功能受损是FD的一种病生理机制。因此恢复肠屏障完整性可能是FD患者治疗的一项可能靶标。该文20
