[Local immunotherapy prevention of recurrent respiratory infections in children].

A group of 20 children aged between 2.5 and 10 years with recurrent respiratory infections (greater than 6/year) was treated with local immunotherapy (Biomunil spray) for a six-month period (October-March 1988/89). Referring to the same period on last year, a statistically significant decrease of upper respiratory infections was observed (p less than 0.001) as well as an increase of S-IgA rate (p less than 0.001) and less of serum IgA and IgG. The compliance and the tolerance of the drug was good.
