[Efficacy and safety of endonasal phototherapy in the treatment of adult allergic rhinitis: A Meta-analysis].

Objective:To perform a systematic review of the efficacy and safety of endonasal phototherapy in the treatment of AR, and to provide evidence of evidence-based medicine for clinical application. Method:Databases were from PubMed, Embase, Cochrane Library, Chinese Academic Journal Full-text Database (CNKI) and Wanfang database. A randomized controlled trial (RCT) or clinical study literature on intranasal phototherapy for adult AR is available, and the deadline is March 2017. Based on the literature inclusion and exclusion criteria, the related literatures were selected and the quality was evaluated by using the Cochrane inclusion bias assessment table. Meta-analysis was performed with Revman 5.3 software. For continuous outcomes, the weighted mean difference (WMD) and its 95% confidence intervals (CI) were calculated, forest maps and funnel plots were drew. For uncontinuous outcomes, the odds ratio (OR) and its 95%CI were calculated, and forest maps and funnel plots were drew. The efficacy included total nasal symptom scores (TNSS), rhinoconjunctivitis quality of life questionnaire (RQLQ) and palate itching scores, and the safety was assessed by incidence rate of severe drying and mild drying of nasal mucosa. Result:A total of 12 articles were selected, including 5 RCT and 7 clinical studies, and there were 615 adult AR patients. The Meta-analysis shows that endonasal phototherapy significantly reduced the TNSS, RQLQ and palate itching scores, the incidence rate of mild drying of nasal mucosa was higher in comparison with pretreated values, and the difference was statistically significant (P<0.05). The rate of severe drying of nasal mucosa was higher, but the difference was not statistically significant (P>0.05). It also shows that endonasal phototherapy significantly reduced the TNSS, RQLQ and palate itching scores, and the rate of mild drying of nasal mucosa was higher in comparison with placebo and antihistamines groups, and the difference was statistically significant. The rate of severe drying of nasal mucosa was higher, but the difference was not statistically significant. Conclusion:Endonasal phototherapy can improve the symptoms of TNSS, RQLQ and palate itching score in patients, and the safety is also confirmed.Patients who are not satisfied with symptom relief may choose to use it.
