In this study, researchers surveyed more than 6,000 adults in Europe for two times in nine years and took blood samples. None of the study participants who have antibodies against the cat in his blood which means they are not sensitive to animal hair and not have allergies to animals.
Sensitivity can also be measured in skin prick tests for signs of allergies. About 3 percent of people who do not keep a cat when surveyed later become sensitive during the study, compared with 5 percent of study participants who have kept the cat for nine years.
In a study published the Journal of Allergy and Clinical Immunology, 4 of 10 people who then become sensitive also claimed to have symptoms of animal allergy. The changes are seen four times in people who do not have antibodies to cats.
The findings of Dr. Mario Olivieri of the University Hospital of Verona in Italy and colleagues confirms that people who keep the cat in her childhood has a much smaller risk of being sensitive to cat hair than people who just keep the cat as an adult.
"We think that the cats at an early age may protect against cat allergies, but this study seems to indicate that this protection extends to adulthood," said Dr. Andy nish of Allergy and Asthma Care Center in Gainesville, Georgia.
This finding also explains that the only people who allow pets into the bedroom which then become sensitive. So, for people who keep cats and have had allergies, pets should be made a new home.
"Adults who suffer from asthma or allergies should think twice if you want to keep the cat. Especially if you let him into the room," said Dr. nish as reported Newsmaxhealth.com, Thursday (12/29/2011).
