Clinical Trial Summary

The goal of The BEGIN Study, a randomized controlled double-blinded intervention trial, is to learn if probiotics, with Bifidobacterium longum subspecies infantis Bifin02 (B. infantis), given to healthy newborns can affect various health outcomes and to explore impacts of the infant gastrointestinal microbiome. The main questions it aims to answer are: - Does B. infantis probiotics impact immune function and does it lower the number of bacterial infections and use of antibiotics? - Does B. infantis probiotics impact overall health, development, growth and wellbeing? - Does B. infantis probiotics impact inflammatory diseases, allergies and autoimmune diseases Researchers will compare B. infantis probiotics to a placebo (a look-alike substance that contains no probiotic) to see if B. infantis colonization impact the human immunesystem and various clinical and biochemical health markers. Participants (parents) will - Orally administrate the B. infantis probiotic to their newborn child daily in three weeks from 7 days of age. - Answer baseline and follow up questionnaires in a study app - Take five stool samples from the child and one stool sample from the mother - Collect a 4 week of passive dust sample at home (Electrostatic Dust fall Collector) - Donate one dried bloodspot and one blood sample from their child

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Hospital admissions	Number of hospital admissions. Registered at Landspatientregistret	First assessment at 1 year and up to 18 years follow-up
Other	Febrile episodes	Number of days with a fever during the last month. A febrile episode is characterized as a body temperature at 38 degrees Celsius or above. Self-reported in a monthly questionnaire in study app.	1 year
Other	Asthma Control Test	Participants reporting symptoms of astma or astmatic bronkitis, will be asked to complete the Asthma Control Test. The scores range from 5 (poor control of asthma) to 25 (complete control of asthma), with higher scores reflecting greater asthma control. An ACT score >19 indicates well-controlled asthma.	1 year, possible later follow-up
Other	Asthmatic Bronchitis, prescriptions	Number of prescriptions of medicine for asthmatic bronchitis; Ventoline, Airomir, Flixotide, Aerobec, Montelukast / Singulair.	First assessment at 1 year
Other	Asthmatic bronchitis, hospitalization	Number of hospitalizations due to asthmatic bronchitis.	First assessment at 1 year
Other	Diaper rash	Atopic skin symptoms in diaper area. Self-reported by the childs parents as affected red skin, distribution in centimeters .	1 year
Other	Rhinoconjunctivitis	Measured as Mini Rhinoconjunctivitis quality of life questionnaire Mini RQLQ, adjusted to infants. 14 questions in five domains (activity limitation, practical problems, nose symptoms, eye symptoms, and non-nose/ eye symptoms), scores for each question is ranging from 0 to 6, with 0 reflecting no affection and 6 reflecting maximum affection.	1 year
Other	Obesity	Measured as number of participants diagnosed with Obesity	18 years
Other	Metabolic syndrome	Measured as number of participants diagnosed with Metabolic syndrome	18 years
Other	Diabetes	Measured as number of participants diagnosed with Diabetes	18 years
Other	Inflammatory bowel disease	Measured as number of participants diagnosed with of Morbus Crohn and/or Colitis Ulcerosa.	18 years
Other	Dried blood spot for metabolomics	The metabolomic method measures and compares large numbers of metabolites (for example shot chained fatty acids) present in the dried blood sample.	3 months and 1 year
Other	Bloodsample analyzed with Singlecell PBMC method	Single cell sequencing is a method profiling the peripheral blood mononuclear cells (PBMC), by isolating memory B, T and B-cells	1 year
Other	Child stool sample	Stool samples collected at week 1, 4, 13, 28 and 52 will by qPCR or shutgun metagenomics examine the gut microbiome.	1 year
Other	Mother stool sample	A stool sample from the pregnant mother, preferably prior to or during birth. To analyze mothers microbial colonization, that may be transferred to the child, e.g during vaginal birth.	1 month
Other	Mother HMO-secretor status	The type of Human Milk Oligosaccharides (HMO) section in mothers' breastmilk, will be determined to exploratively study the relationship between types of HMO's, mothers HMO-secretor status and effects of B.infantis.	1 month
Other	Asthma	Number of participants with prescriptions of medicine for asthma	up to 18 years follow-up
Other	Atopic disease (adjusted SCORAD grading)	Atopic symptoms, eczema, registered in study-app with description of episodes of atopic dermatitis (adjusted SCORAD grading). Disease intensity is calculated based on six characteristics: erythema, edema, oozing/crusts, excoriations, lichenification, and dryness. Each characteristic is given a score between 0 and 3, where 0 is absent and 3 is severe. The scores for each characteristic are added together for a total intensity score of up to 18.
