Plain English Summary
Background and study aims
Colic is excessive, frequent crying in a baby who appears to be otherwise healthy. It is known that 38% or more cases of infant colic are related to a temporary lack of the lactase enzyme, causing lactose (a sugar found in milk) to build up in the gut and then ferment. By providing lactase in the milk feed, the lactose will be digested. The aim of this study is to assess the effect of lactase (as the marketed product Colief) in the treatment of young babies who have colic.
Who can participate?
Babies between the ages of 21 and 90 days with abdominal colic
What does the study involve?
Participating babies are randomly allocated to have either lactase or a placebo (dummy drug) added to their formula milk feeds over two 10-day periods with a 4-day break in between. Improvement in colic symptoms is assessed by measuring crying time using a diary completed by the parent or guardian during the two treatment periods. Other than physical examination of the babies the study does not involve intervention of any kind (e.g. blood samples or X-rays).
What are the possible benefits and risks of participating?
Babies may benefit from relief of their abdominal colic if the symptoms are due to lactase deficiency. Parents/guardians may therefore benefit from reducing their anxiety levels and improving their sleep patterns. If the symptoms are reduced, the product (Colief®) is available for purchase. There are no other lactase products for infants demonstrated as effective and so without alternatives the infant would probably continue to have symptoms until lactase is produced naturally. The tested product is a nutritional supplement (natural biological product) added to the formula feeds in low doses and as such the foreseeable risks are negligible. The product has also been available on the market in many countries for many years.
