Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In a prospective randomized study the investigators aim to obtain preliminary results about the impact of gut-directed hypnotherapy (GDH) modified for self-practicing and probiotic nutritional supplement (NS) on symptoms in children with pain-related FGIDs (IBS and FAP). This is going to be measured by the mean of number of days the children experience no abdominal pain or discomfort. Beside that the investigators plan to obtain data on abdominal pain intensity and duration and about the effects of above mentioned interventions on children's health-related quality of life (KINDL-R), pain-related disability (P-PDI), their coping abilities (PPCI) and behavioural and emotional problems (CBCL). The information obtained from children as well as from parental perspective will allow more extensive models on mechanisms of change.
Beyond psychometric instruments some well-established psychophysiological methods will be used. Assessment of the heart rate variability under mental stress conditions (Parametric Go/No-Go test) and measuring of cortisol awakening response (CAR) are used to study the function of autonomic nerve system and stress-level/tolerance of the study population.
The investigators hypothesize:
1. a significant decrease in number of days with pain/discomfort in both intervention groups (GDH, NS) as compared to the control group (active waiting-list control group)
2. that both types of intervention lead to an increase of quality of life and decrease of pain duration, intensity and pain-related disability as compared to the control group.
3. a decrease of physiological stress parameters (as measured by heart rate variability \[HRV\] analysis, cortisol awakening response \[CAR\]) in both intervention groups as compared to the control group, but more prominent in GDH group.
The data of this pilot study will be used for further projects where the most promising intervention and research parameters will be investigated more detailed in a larger sample.
Current study is regarded as a pilot and is conducted in order to obtain information about the efficacy of GDH and probiotic intervention in children with IBS or FAP as compared to reference group. Based on our previous studies and data of literature the investigators expect to see moderate effect power of the primary outcome measure (η²\~.06). In order to detect a 50% improvement of symptoms during 4 week treatment with 80% power, assuming α=.05 and using a 2 x 3 repeated measure design for the main analysis, 51 participants should be included in the study. Taking into account possible dropouts the investigators plan to recruit 60 children (20 children per group).
Short description of study protocol: Parents that are interested in the study after a first contact with the investigators will receive detailed informations about the study and a short anamnestic questionnaire. After returning it they will be invited together with their children for the diagnostic appointment ("Visit I"). Inclusion into the study will be made based on the results of anamnestic interview as well as based on the reports from the responsible gastroenterologist regarding exclusion of other possible reason for the symptoms (including organic disorder, e.g. Celiac disease). Participants and their parents will also receive all necessary information about goals of the study and methods used in the study as well as about possible health risks from applied interventions. Informed consent is to be signed prior inclusion in the study. After inclusion, children and parents will be asked not to change any currently used medications or to undertake another treatment, as well as not to change usual habits until the end of the follow-up period.
Participants will be filling in diaries that will question about their symptoms once a day.
During the first two weeks ("run-in period") participants will only be keeping their symptom diaries. This data will be used in later analysis as "baseline" data for comparison with any changes that will occur due to intervention. The week three and four are regarded as "wash-out period": participants will be instructed to stop answering questions in diaries. The investigators hypothesize that this will reduce the effect of self-monitoring when the treatment starts.
At the end of week four, children will be randomized into one of three groups: based on computer generated table of random numbers each participant will be allocated either to a group practicing a gut-directed hypnosis or receiving a probiotic for the next four weeks (SymbioLact B) or reference group (only symptom diaries). Participants are randomized with an aspect ratio 1:1:1. Children will continue to keep the symptom diaries for another two weeks (week 9 and 10) and will return them to the investigators during "Visit II" at the end of 10th week.
Visits I and II will also be used to collect psychometric data from children and their parents as well as psychophysiological measures (HRV). Saliva samples should be collected at home: participants will be provided with appropriate collection tubes as well as with detailed instructions on how to collect, store and deliver samples to the investigation site. Baseline saliva samples should be collected inside the first week and during week 10 (in a morning before Visit II).
For ethical reasons, a second intervention can be chosen freely by the family after the follow-up period.
Risks of the study: A systematic review and meta-analysis of randomized clinical trials about the effects of probiotic in children with pain-related FGID as well as RCTs report seldom or no adverse effects from probiotics. If appeared - most often in a form of gastroenteritis and vomiting - the adverse effects were comparable to those in a placebo group. Based on previous studies of our group we expect no adverse events from gut directed hypnosis. All adverse events in any group will be documented and reported.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Gut-Directed Hypnotherapy (GDH)
Gut-Directed Hypnotherapy on a daily basis (20 min each day, at least 4 times/week)
Gut-Directed Hypnotherapy
Hypnotherapy protocol is based on the Manchester protocol for gut-directed hypnotherapy and was adapted for children and adolescents. It consists of elements aiming at relaxation and suggestions for control and relief from pain and discomfort. The hypnotherapy will be provided using a CD. Children of the hypnotherapy condition will be instructed to practice with their CD on a daily basis (20 min each day, at least 4 times/week) during 4 weeks
Self-Monitoring
Use of symptom diary that questions about main bowel complains (including pain or discomfort) during the day. Applied on a daily basis (about 2 min in the evening)
Probiotic (NS)
Nutritional supplement SymbioLact B once a day diluted in water or tea
Nutritional Supplement
SymbioLact® B a preparation of Bifidobacterium lactis and vitamin B7, Biotin. Number of living organisms in one dose is at least 1 x 10\^9 cfu. SymbioLact® B will be used in the dose recommended in the pediatric patient information sheet - one dose of SymbioLact® B diluted in water or tee once a day together with a main meal during 4 weeks
Self-Monitoring
Use of symptom diary that questions about main bowel complains (including pain or discomfort) during the day. Applied on a daily basis (about 2 min in the evening)
Active Controls (AC)
AC group keeps a symptom dairy (self-monitoring)
Self-Monitoring
Use of symptom diary that questions about main bowel complains (including pain or discomfort) during the day. Applied on a daily basis (about 2 min in the evening)
