Children with skin, food and respiratory allergies should be screened for an emerging, chronic food allergy called eosinophilic esophagitis (EoE). It is a painful inflammation of the oesophagus, the food tube between the mouth and stomach. Pediatric allergists who examined a very large group of children from birth to adolescence say that EoE should be considered a later component of the "allergic march". The "allergic march," a pillar concept in allergy, is usually compressed into the first few years of life. The characteristic childhood progression is a skin allergy, such as atopic dermatitis. It is followed by an anaphylactic food allergy, then a respiratory allergy, such as asthma. As per studies, EoE was a component of the allergic march. The more allergies a child has, the greater is that child's risk of developing EoE. The association among these allergies suggests a common underlying biological cause. It also may imply that if we can successfully get treated an earlier type of allergy, we may prevent later allergies. As compared to classic, potentially life-threatening anaphylactic food allergies, EoE has low mortality, but high morbidity. It has slow-onset symptoms, such as pain in swallowing, stomach ache, even food impaction. Both types of allergies are activated by specific foods. But, the culprit in EoE may not be clear. A child may need to follow a controlled diet until healthcare providers can pinpoint the offending food. Further investigations regarding the underlying biological mechanisms among different allergies has been going on regarding preventing the child from developing disorders such as EoE. If your child has been suffering from severe allergy issues, you must immediately consult a qualified Allergy Specialist.
