Background:
The incidence of allergic diseases has increased worldwide. Thus, there is a need for effective primary prevention of allergies.
Objective:
The aim of the present study was to examine how allergen-specific immunotherapy (ASIT) affects the development of allergies in the generation of children whose parents were subjected to this method of treatment.
Methods:
A total of 194 children with at least one parent with allergy subjected to ASIT were enrolled. These patients were compared with control individuals without ASIT. Their risk of allergy, based on medical history, examination, allergy skin-prick tests, serum total immunoglobulin E and specific immunoglobulin E concentrations was assessed.
Results:
The children of parents subjected to immunotherapy showed significantly reduced clinical symptoms of allergic disease. The odds ratios (OR) of any allergic disease and asthma were significantly lower in children with one or both parents with allergy after ASIT compared with the children with parents with allergy and without ASIT: OR 0.73 (95% confidence interval [CI], 0.59-0.86) versus OR 1.85 (95% CI, 1.73-2.2) for any allergic disease and OR 0.63 (95% CI, 0.53-0.79) versus OR 1.36 (95% CI, 1.22-1.67) for asthma.
Conclusion:
The phenomenon of reducing the risk of allergies in children whose parents were desensitized might be important in the primary prevention of allergies.

01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
