Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will consist in a oral administration of a commercially avaliable extensively hydrolyzed casein formula (EHCF) containing LGG (concentration was 2,50x 10 7 to 5x10 8 colony-forming units /CFU/g).
The amount of EHCF ranged from 500 to 1000 ml per day depending on the body weight and age of children. Children enrolled will receive this dietary intervention untill tolerance will be acquired as demonstrated by oral food challenge (OFC)

Comparator / control treatment
The control group will receive commercially avaliable extensively hydrolyzed casein formula (EHCF) with the same composition with the exception of absence of LGG

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be allocated into one of the 2 groups according to a computer-generated randomization list.
The list will be concealed and parents of enrolled children received a sealed opaque envelope containing instruction about dietary product to be used
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation by using block randomisation created by computer software
Masking / blinding
Open (masking not used)

Summary
Brief summary
BACKGROUND. Lactobacillus GG (LGG) modulates immune function and has been proposed in the prevention and treatment of pediatric allergic diseases.

AIM. We investigated whether the addition of LGG to an extensively hydrolyzed casein formula (EHCF) could be able to influence the time of tolerance acquisition in children affected by cow’s milk allergy (CMA).

METHODS. Children (1-24 months of age) affected by immunoglobulin E (IgE) and non immunoglobulin E (non-IgE) mediated CMA, confirmed by oral food challenge, were randomly allocated to two different dietary interventions: 1, EHCF (Nutramigen'Registered Trademark (R)', Mead Johnson, Italy); 2, EHCF containing LGG for at least 1x106 CFU/g of formula powder LGG (Nutramigen LGG 'Registered Trademark (R)', Mead Johnson, Italy). To investigate the possible tolerance acquisition an oral food challenge was performed every 3 months after diagnosis for 12 months.
