The aim of this study was to evaluate the effect of daily intake of LongoVital (LV) (herbal vitamin tablets) in the prevention of RAS.
A group of 78 consecutively referred patients was enrolled to a three-months pretreatment period. Fifty subjects were then randomly allocated to an LV-group (n = 25) or a placebo group (N = 25). A double blind, stratified-randomised clinical case-control study was performed during six months. Number and size of the ulcers were registered by the patients using a standardized chart. The degree of discomfort was recorded on a 100 mm horizontal visual analogue scale (VAS-scale).
The three-months pretreatment period revealed that the most dominant symptoms were pain (78%) followed by burning sensation (18%). No significant differences between the two groups were found during this period when a comparison was made at the end of the study. After the intervention period the number of aphthous ulcers/month decreased significantly in the LV-group (p = 0.02). The number of days in pain/month were also reduced (p < 0.001). If a 50% reduction of number of aphthous ulcers and days in pain were considered as clinically relevant, no statistical significant differences were found between the groups.
Thus, no strong evidence was found that justified a recommendation of LV as a general drug for treatment of RAS.
本研究旨在评估每日摄入LongoVital(LV,草本维生素片)对复发性口疮性口炎(RAS)的预防效果。
一组78例连续转诊患者进入为期三个月的预处理期。然后,50名受试者被随机分为LV组(n = 25)或安慰剂组(N = 25)。在六个月期间进行了一项双盲、分层随机临床病例对照研究。患者使用标准化图表记录溃疡的数量和大小。不适程度通过100毫米水平视觉模拟量表(VAS量表)记录。
为期三个月的预处理期显示,最主要的症状是疼痛(78%),其次是烧灼感(18%)。在研究结束时进行比较时,在此期间两组之间未发现显著差异。干预期后,LV组每月复发性口疮溃疡的数量显著减少(p = 0.02)。每月疼痛天数也减少了(p < 0.001)。如果将复发性口疮溃疡数量和疼痛天数减少50%视为具有临床相关性,则两组之间未发现统计学上的显著差异。
因此,没有充分证据支持推荐LV作为治疗RAS的常规药物。
