养宠物可能预防新生儿过敏
Pets might not be as bad for allergies as currentlythought.
Researchers said Saturday their new studies suggest there could be protectiveeffects against allergies if a baby is raised with a cat or a dog.
Admitting that the study is contrary to accepted beliefs, Christine Johnson ofthe Josephine Ford Cancer Center in Detroit, said that in her study conductedamong more than 700 children, the seven-year-olds raised from birth with a cator dog showed less allergic sensitivity when looking at three key markers.

"I think the data is still too premature to recommend that people get a pet ifthey have a newborn," said Dr. Dennis Ownby, professor of pediatrics andmedicine at the Medical College of Georgia, Augusta, and co-author of the studypresented at the annual meeting of the American Academy of Allergy, Asthma andImmunology (AAAAI). "However," Johnson said, "I wouldn’t encourage a person toget rid of the pet either."
The report flies in the face of advice allergists have been advising for years."Animals do not belong in the home," said Dr. Richard Lockey, professor ofmedicine, pediatrics and public health at the University of South FloridaCollege of Medicine, Tampa, and a past president of the AAAAI.

Ownby said, "I think we have to reexamine that saying. This study suggests thata pet may have beneficial effects.. this is a major controversy. A lot ofphysicians have felt very strongly that pets are always bad."
Johnson said that researchers believed that they would find confirmatoryinformation in their long-term study that would support a European researchersuggesting that pets in the first year of life might inhibit allergic reactionsamong children. "We were thinking we would see the same thing," she said. "Wewere looking for a protective effect and we found it." She suggested that petsearly in life have some effect in the maturation of an infant’s immune systemwhich offers protection. However, she said that was just speculation.

In her study, children raised with pets had significantly lower levels of bloodmarkers for allergies, and were less likely to show positive skin tests forallergies than children raised in similar suburban Detroit homes.
Johnson said there were several caveats to her study: * Having pets will notdiminish the severity of allergic reactions for people who already have asthmaor allergies. * Pets in the first year of life do not seem to protect againstasthma, although there is little evidence to say that pets contribute to thedevelopment of asthma, either., 百拇医药
