Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with relief of IBS condition | 6 months after the treatment | The responder should at the same time get relief of at least one item of abdominal discomfort related symptoms(including abdominal pain score(0-10 with 0 indicates no pain and 10 indicates very great deal of pain) and bloating/abdominal discomfort score(0-10 with 0 indicates no discomfort and 10 indicates very great deal of discomfort), both items' effectiveness are defined as decreasing at least 30% compared with baseline) and at least one item of defecation related abnomalities(including average daily defecation(effectiveness defined as decreasing at least 30% compared with baseline) and stool consistency(effectiveness defined as feces could reach at least Bristol type 5) ). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with relief of IBS related anxiety or depression status | 1 month/2 month/3 month/6 month after the treatment | The number of patients who have at least 30% decreasing compared with baseline in the score of SAS/SDS/HADS rating scale |
| Number of patients with relief of IBS single symptoms | 2 week/1 month/2 month/3 month/6 month after the treatment | The number of patients who have relief of IBS global score(0-10 with 0 indicates no discomfort and 10 indicates very great deal of discomfort), pain score(0-10 with 0 indicates no pain and 10 indicates very great deal of pain), bloating/abdominal discomfort score(0-10 with 0 indicates no discomfort and 10 indicateds very great deal of discomfort), urgency score(0-3 with 0 indicates no urgency and 3 indicates great deal of urgency), average daily defecation, stool consistency(according to Bristol criteria). Except stool consistency, other items' effectiveness are defined as decreasing at least 30% compared with baseline during the whole period of follow-up. Stool consistency's effectiveness is defined as feces could reach at least Bristol type 5 during the whole period of follow-up. |
Other
| Measure | Time frame | Description |
|---|---|---|
| The rate and type of adverse effects | The day before check-out and 2 week/1 month/2 month/3 month/6 month after the treatment | It means any events that occur in the trial process related or unrelated to the drug/fecal microbiota transplantation that do harm to the patients' health, including symptoms/physical signs/abnormal lab values |
