A dog can help protect against childhood eczema

The study found that children who tested positive for allergies to the dog and not living with a dog has four times the risk of eczema than those who tested positive and did not own a dog four years. People can test positive for allergies, but have no symptoms, experts say.The jury is still out, said Phipatanakul, who is also an associate professor of pediatrics at Harvard Medical School. I do not think anyone, including the authors, said he had some dogs, a cat or don t take to reduce the risk.

The study was done using children in the Cincinnati area, whose parents had allergies or eczema, which makes children more likely to develop the disease. Skin tests were performed to determine which children were allergic to dogs and cats, regardless of whether their families had either.

People with allergies should avoid the causes of their allergies, or keeps the symptoms, he said.

They have done a lot of advanced analysis and looked at [the data] in detail, Phipatanakul said, adding that encourages further research to help doctors learn more and better use of interventions or strategies.

It’s speculative, but possible that the protective effect is due to a natural kind of immunotherapy in which children are exposed dogs become tolerant over time in the same way that people on allergy shots to develop a tolerance to allergens, said study author Dr. Tolly Epstein, assistant professor in the Division of Immunology, Allergy and Rheumatology at the University of Cincinnati Medical School.

Phipatanakul said the study, published in the next edition of the Journal of Pediatrics release, has been carefully done, but was not final. Other studies have shown conflicting results on the impact of dogs and cats, he said.

We tend to be so focused on food allergies with children, but the study showed aeroallergens [airborne allergens such as pet dander or automobile emissions] may be more important than what has already been realized, said Epstein .

Epstein said that the rate of eczema increased significantly over the past 30 years, and researchers want to understand the causes.

Man’s best friend’s protection against eczema in young children, but his nemesis, the cat, not a new study.

Children with a dog at home at the age of 1 had a significantly reduced risk of eczema at age 4, but children who had a cat were more likely to have the evil of the same age, according to the study. Dog ownership also protects against becoming allergic to cats.

The study also examined the association between eczema and eggs, milk and nuts, some of the most common food allergies in infants. Some experts recommend delaying common food allergies as a strategy to protect children against allergies, but the results of the study do not support this.

Diet is not recommended for babies solid foods before six months, with the introduction of cereals will monitor the effects, said Dr.
