Allergie Alimentari? I Doctors do not know exactly what they are

And 'what emerges from a study published in the Journal of American Medical Association
titled: Diagnosis and management of common allergies and intolerances.


Chafen Schneider JJ, et al "Diagnosis and managing common food allergies," JAMA 2010, 303 (18): 1848-56.


The lack of clear definitions prevents coherent collection of data and the ability to program good clinical research and interventions for prevention and treatment.

" This systematic review of the evidence shows that food allergy prevalence, diagnosis, management and prevention is voluminous, widespread, but limited by a critical lack of uniformity in the diagnostic field, and this severely limits the versatile and complete to draw conclusions on best practices for the management and prevention .

The review considered 72 clinical research: a meta-analysis of the incidence and prevalence, 18 studies on the diagnosis, and 53 on management and prevention .

When it comes to head start coming home to roost as the nodes are too many methods used to determine food allergies (history, skin tests, IgE etc.).

In the case of allergies reported by patients and not verified in the laboratory, the prevalence was as follows:
Cows' Eggs
3.5%: 1.3%
Peanuts: 0.75%
Fish: 0.6%
Crustaceans: 1.1%
and soybeans? Seems to be missing one of the most common food allergens other studies ....


allergies and intolerances are on the rise?
to this question also the study was not able to respond
According to the U.S. population-based studies analyzed only one showed a significant growth falling from 3.3% of children in 1997 to 3.9% 2007.


there a test better than another?
The study can not provide an answer ..
" loads food, skin-prick testing, specific IgE in serum all have a role in determining the diagnosis but no test has a sensitivity and ease of use that it must be considered better than others " say the researchers Jama

and management of allergies and intolerances?
Looking at 25 studies and clinical investigations have found 7 different strategies:

• ELIMINATION
• IMMUNOTHERAPY
• REPLACEMENT OF FOOD
• DIET IN BREAST
• MEDICAL TREATMENTS AND PHARMACOLOGICAL
• PROBIOTICS
• NUTRITION EDUCATION PROGRAMS
  

deletion and immunotherapy are poorly studied, showed the first results in atopic dermatitis; hydrolyzed formulas may reduce intolerance in children with allergies to cow's milk;
Probiotics may reduce skin problems in children;

In conclusion, the researchers admit that despite the enormous amount of studies on the fundamental questions remain open:

Prevalence, diagnosis, prevention and treatment of allergies and food allergies are still a problem faced by modern medicine.
