Description

風邪様症状の改善のための組成物Composition for improving cold-like symptoms
 本開示は、風邪様症状の改善のための組成物に関する。より詳しくは、ワイツマニア・コアギュランスの生菌を含む、風邪様症状の改善のための組成物に関する。 The present disclosure relates to compositions for improving cold-like symptoms. More particularly, the present invention relates to a composition for ameliorating cold-like symptoms, containing viable Weitzmania coagulans bacteria.
 ワイツマニア・コアギュランスSANK70258(シノニム:バチルス・コアギュランスSANK70258)は、1949年に緑麦芽から分離された、高い乳酸生成力を有する有胞子性乳酸菌である。ワイツマニア・コアギュランスSANK70258を配合した食品用製剤(商品名:ラクリス)が、1966年から50年以上にわたって販売されている。 Weitzmania coagulans SANK70258 (synonym: Bacillus coagulans SANK70258) is a spore-forming lactic acid bacterium isolated from green malt in 1949 with high lactic acid-producing ability. A food formulation containing Weitzmania coagulans SANK70258 (trade name: Lacris) has been on the market for more than 50 years since 1966.
 本開示に関連して、特許文献1には、バシラス・コアギュランスに由来する成分を用いて微生物病原体に対する免疫応答を増強する方法が開示されている。当該文献の試験例で生理活性が評価されている成分は、バシラス・コアギュランスの細胞壁成分や培養上清であり、バシラス・コアギュランスの生菌ではない。 In relation to the present disclosure, Patent Document 1 discloses a method of enhancing an immune response against microbial pathogens using components derived from Bacillus coagulans. The components whose bioactivity has been evaluated in the test examples of the literature are the cell wall components and culture supernatant of Bacillus coagulans, not the viable bacteria of Bacillus coagulans.

I thought I could do it. However, if cold symptoms (fever, sore throat, cough, runny nose, etc.) and infectious diarrhea symptoms develop within 7 days before the scheduled examination visit, 7 days after the subjective symptoms disappear regardless of the above regulations After that, it was decided that the inspection date could be changed. However, if the examination date exceeds 14 days from the prescribed examination date due to the above-mentioned cold symptoms (fever, sore throat, cough, runny nose, etc.) and infectious diarrhea symptoms, It was decided that the test could be performed on the day the subject could come to the hospital, even if it was within 7 days after the disappearance of symptoms.

評価方法
(1) 主要評価項目
1) 風邪様症状の記録
 各被験者の摂取期間日数を規定摂取期間日数(56)で除した数値を相対摂取期間比率とした。
●累計発症日数
 各被験者の摂取期間中の風邪様症状有症日の日数を合計し、その合計値と相対摂取期間比率の積を算出し、累計発症日数とした。各群の累計発症日数をMann-Whitney U検定を用いて評価した。また、必要に応じて適切な解析を行った。
●累積スコア
 各症状について、摂取期間の各症状のスコアを合計し、その合計値と相対摂取期間比率の積を算出し、累積スコアとした。各群の累積スコアをMann-Whitney U検定を用いて評価した。また、必要に応じて適切な解析を行った。
 なお、累積発症日数及び累積スコアは、ウィスコンシン上気道症状調査票(WURSS)等の調査項目を参考として風邪様症状を毎日記録させ、評価した。各症状のスコアは「症状なし」を0点、「ひどく重い」を7点とする8段階で評価した。
Evaluation method
(1) Primary endpoint
1) Records of cold-like symptoms A relative intake period ratio was obtained by dividing the intake period days for each subject by the prescribed intake period days (56).
● Cumulative number of days of onset The number of days with cold-like symptoms during the intake period for each subject was totaled, and the product of the total value and the ratio of the relative intake period was calculated as the cumulative number of days of onset. The Mann-Whitney U test was used to evaluate the cumulative number of days of onset in each group. Appropriate analysis was also performed as necessary.
● Cumulative Score For each symptom, the score of each symptom during the intake period was totaled, and the product of the total value and the relative intake period ratio was calculated as the cumulative score. Cumulative scores for each group were evaluated using the Mann-Whitney U test. Appropriate analysis was also performed as necessary.
The cumulative number of days of onset and the cumulative score were evaluated by recording cold-like symptoms every day with reference to survey items such as the Wisconsin Upper Respiratory Symptom Questionnaire (WURSS). Each symptom was scored on an 8-point scale, with 0 being "no symptoms" and 7 being "very severe".
2) 唾液中s-IgA、糞便IgA
 8週目の摂取前からの変化量について、被験食品摂取群をプラセボ摂取群と2標本t検定を用いて比較した。また、参考として、4週目の変化量についても同様に比較した。なお、各群それぞれにおいて摂取後各時点の測定値を、1標本t検定を用いて評価も行った。また、必要に応じて適切な解析を行った。
2) Salivary s-IgA, Fecal IgA
The test food intake group was compared with the placebo intake group using a two-sample t-test for the amount of change from before intake at week 8. As a reference, the amount of change at week 4 was similarly compared. In each group, the measured values at each time point after ingestion were also evaluated using the one-sample t-test. Appropriate analysis was also performed as necessary.

5-3 Additional analysis Regarding cold-like symptoms, an analysis was also conducted on 53 subjects, excluding 26 subjects who reported hay fever in advance or in their diaries during the intake period. In addition, in order to consider the mechanism of action for the improvement of cold-like symptoms in group A, principal component analysis was performed on the results of cold-like symptom items at a research institution, and subjects were clustered using the principal component scores. The results of principal component analysis are shown in FIGS. 1 and 2. FIG. For clustering, the top 6 principal components (top principal components with a cumulative contribution rate of 90% or more) were used, the distance function during clustering was the Euclidean distance, and the clustering method was the Ward's method. As a result, an additional analysis of the objective index among the evaluation items was performed for the group of 38 people who were considered to be healthy during the intake period. The analysis results are shown in Table 10.
