Effects and tolerability of betahistine in patients with vestibular vertigo: results from the Romanian contingent of the OSVaLD study

The Clinical Benefit of Device Therapy for Meniere's Disease in Adults: Systematic Review and Meta-Analysis

OBJECTIVES

This study aimed to assess the clinical benefit of device therapy on controlling the symptoms of Meniere's disease (MD).

MATERIALS AND METHODS

We searched PubMed, Embase, the Cochrane Library, China National Knowledge Internet, and Wanfang Data before January 13, 2018. We selected randomized controlled clinical trials, case-controlled studies, and cohort studies that dealt with outcomes of device therapy for the treatment of MD.

RESULTS

Sixteen trials met our inclusion criteria. The use of device therapy resulted in improved vertigo control, which was described as a reduction in the number of vertigo days by month (weighted mean difference [WMD]: 3.15, 95% confidence interval [CI]: 2.00-4.31), in the number of vertigo episodes by month (WMD: 7.37, 95% CI: 2.40-12.35), and in the vertigo visual analog score (WMD: 41.51, 95% CI: 34.68-48.34). In addition, the overall complete vertigo control (class A) rate was 50% (95% CI: 37%-64%). The device therapy also reduced the number of sick days by month (WMD: 4.56, 95% CI: 2.15-6.97), and the functional level improved (WMD: 2.66, 95% CI: 2.15-3.17). The electrocochleographic parameters decreased. The device therapy proved beneficial for hearing changes (WMD: 3.19, 95% CI: 0.66-5.71). No publication bias was found in the funnel plot and the results of Egger's test.

CONCLUSION

This study showed that the device therapy might reduce vertigo attacks and sick days in patients with MD. Additionally, the function level and hearing level may improve after the device therapy. In addition, the decrease in electrocochleographic parameters showed that inner ear electrophysiology improved after device therapy.

Acupuncture Points Stimulation for Meniere's Disease/Syndrome: A Promising Therapeutic Approach

Objective. This study aims to explore evidence for acupuncture points stimulation (APS) in treatment of Meniere's disease (MD). Method. A literature search was conducted in seven databases including EMBASE, Medline, Cochrane Library, Web of Science, CBM, CNKI, and WangFang database and the data analysis was performed by using the RevMan version 5.3. Results. 12 RCTs with 993 participants were acquired after the search. The quality of most eligible studies was very low which limited the value of the meta-analysis. Compared with western medicine comprehensive treatment (WMCT), the APS alone or in combination with WMCT had a significant positive effect in controlling vertigo; however, the result was negative in hearing improvement and DHI. No adverse events were reported in the studies. Conclusion. The APS might be a promising therapeutic approach for MD. However, the currently available evidence is insufficient to make a definitive conclusion for the poor quality of included studies. More high-quality researches with larger sample size are urgently needed to assess the effectiveness and safety.
