Quality of life improvement with soy sauce ingredients, Shoyu polysaccharides, in perennial allergic rhinitis: A double-blind placebo-controlled clinical study

Allergic rhinitis (AR) is a common disease that interferes with the daily activities and reduces the quality of life. Conventional treatments often do not provide complete resolution of the symptoms, and many new treatment modalities have been tried. This study aimed to evaluate the efficacy and safety of low-level laser therapy (LLLT) for AR in a randomized, double-blind, placebo-controlled trial. Patients diagnosed with AR were randomly allocated to receive LLLT or sham treatment. The primary outcome was a change in the reflective total nasal symptom score (TNSS). The secondary outcome was quality of life scores assessed using the Rhinoconjunctivitis Quality of Life Questionnaire. Incidences of adverse events were also recorded. Among 67 randomized subjects, 41 subjects (22 in LLLT group and 19 in sham treatment group) were included for efficacy analysis. The LLLT group showed a significantly improved TNSS score compared to the sham treatment group for decreasing AR symptom severity (p = 0.011) and improving quality of life regarding nasal symptoms (p = 0.036) at the end of treatment. Throughout the treatment period, no severe adverse events occurred. This clinical trial showed that LLLT is an effective and safe option for the management of AR regarding symptom relief and quality of life improvement.

AbstractObjective:This study investigated improvements in quality of life associated with eight weeks of montelukast and/or intranasal steroid treatment for moderate to severe allergic rhinitis.Methods:A single-centre, prospective, randomised, double-blind, placebo-controlled study was carried out. Assessments were made using the Rhinoconjunctivitis Quality of Life Questionnaire and symptom scales.Results:A total of 128 patients (aged 13–51 years) were randomly assigned to one of two groups. In the montelukast group, patients were treated with montelukast tablets and fluticasone propionate nasal spray (n = 64). In the placebo group, treatment comprised a placebo and fluticasone propionate. The results showed significant improvements in symptom scores and quality of life scores for both groups after one month and two months of treatment, compared with baseline values; these improvements were significantly greater for the montelukast group compared with the placebo group. The mean number of loratadine tablets taken by each patient during the study period was only 0.73 for the montelukast group compared with 9 for the placebo group.Conclusion:The combination of montelukast tablets and fluticasone propionate nasal spray improved symptom control and overall quality of life for moderate to severe allergic rhinitis patients.
