| 目的/Objectives | ||
| 目的1/Narrative objectives1 | 牛乳摂取で腹部の自覚症状のある人を対象に、乳糖減量牛乳の摂取で臨床症状が誘発されないことを確認してから(心因性のものを除外)、乳糖を含む一般牛乳を少量から摂取開始し、漸増しながら毎日摂取(牛乳漸増負荷)することで、乳糖吸収能が改善され臨床症状が軽減(乳糖耐性獲得)するかどうかを調査する。また、牛乳漸増負荷前と後で、腸内細菌叢が変化しているかどうか、その役割についても検討する。 | Patients who complain of abdominal symptoms due to cow's milk consumption are screened to make sure that there are no clinical symptoms induced by consumption of cow's milk with reduced lactose (excluding psychogenic causes), followed by starting small dosage of general cow's milk with lactose of which amount is incrementally increased (incremental increase of lactose load) on daily basis in order to investigate the improved lactose absorption capacity and the reduced clinical symptoms (acquirement of lactose tolerance). Moreover, changes in intestinal bacterial flora, as well as its roles, are evaluated among before and after the treatment. |

②乳糖負荷試験の結果から、真の乳糖不耐症の比率 ③以下の項目の治療前後の変化 乳糖負荷試験、腸内細菌叢 |
1.Ratio of abdominal symptoms (such as psychogenic causes) in single blind comparative study on cow's milk and lactose-reduced milk
2.Ratio of true lactose intolerance from the result of lactose tolerance test 3.Changes in before and after the treatment listed below Lactose tolerance test and intestinal bacterial flora |

| 介入1/Interventions/Control_1 | 牛乳乳製品摂取で腹部症状の
ある人アンケート調査で選定 し、同意を得られた研究協力者 に対し、乳糖減量牛乳と一般 牛乳の200ml摂取を単盲検比 較試験でそれぞれ1週間以上 あけて行い、腹部症状を調査 する。 上記の研究①で一般牛乳でのみ腹部症状がある人を対象に、次の乳糖耐性獲得治療の実施前に乳糖負荷試験と検便を行う。 乳糖耐性獲得治療 牛乳(乳糖)不耐症の確定診断に至った被験者には、毎日ほぼ同じ時間の空腹時に、一般牛乳を少量(30ml)摂取から開始し、症状がなければ4日ごとに30mlずつ増やし、症状があれば最大7日 まで同じ量を摂取し続ける。最大8 週間かけて200ml以上まで飲用させ、その間日誌をつけて臨床症状の経過を確認する。 乳糖耐性獲得治療の終了時に乳糖負荷試験と検便を再び行う。 |
After screening by questionnaire survey and agreement to informed consent for the patients with abdominal symptoms due to diary consumption, a single blind comparative study is conducted by observing the abdominal symptoms after dosage of 200ml of lactose-reduced milk and general cow's milk with an interval of 1 week or longer.
Eligible patients with abdominal symptoms only due to cow's milk from the above study have lactose tolerance test and be taken their stool samples prior to the following treatment for lactose tolerance acquirement. Treatment for lactose tolerance acquirement The treatment on eligible patients with cow's milk (lactose) intolerance from definitive diagnosis starts with small dosage (30ml) of cow's milk around the same time each day on an empty stomach. If there was no abdominal symptom, the dosage is increased by 30ml with 4 days interval. If the symptoms presented, the same amount is kept for up to 7 days. The study continues up to 8 weeks until the dosage increases to 200ml or more. The daily record of the symptoms is given by each patient during the treatment period. At the end of the treatment for lactose tolerance acquirement, lactose tolerance test is performed and stool samples are taken on the subjects. |
