Dogs growing around dogs The possibility of developing is less AsthmaNew research has been found.
A study by a team from hospital for sick Children In Canada It is found that young children had reduced the risk of coming in contact with dog allergies in their home Asthma By the age of five, but the cat was not exposed to allergies The same protective effect,
Infants who were conveyed to the high levels of dog allergen were about 48 percent of the growth of asthma at the age of five than other infants. He also had a better lung work. The protective effect was even stronger for infants who were at high genetic risk of worse lung function.
Scientists analyzed dust samples from the homes of 1,050 children, part of the Canadian Child Caurt Studies, when they were between three and four months. For every child, Researcher The amount of three potential allergies in dust measured: whether F1, a protein shade dog skin and saliva, fail D1, which can be found in cat’s skin and saliva, as well as endotoxin – a molecule on the surface of the bacterial.
No protective effects were discovered for infants coming in contact with cat allergen or endotoxin.
These children were then evaluated by a doctor to asthma when they were five years old; Their lung function was measured on the basis of how much air they could blow in a second after a deep breath. They were also evaluated for genetic risk factors for asthma and allergies through blood samples.
Researchers, who are ready to present their work at the European Respiratory Society Congress at Amsterdam, said indoor allergies were an important risk factor that could be potentially changed to reduce asthma.
Speaking in front of Congress, Dr. Jacob McCoy said: “Asthma is a very common chronic respiratory disease in children, with the highest rate in the first four years of life. It is caused by complex interaction between genetic factors and environment, including infection, allergies and air pollution.
“Children spend most of their time indoors, so in this research we wanted to study allergies in the house. These are an important risk factor that we can potentially change to reduce asthma.”
Dr. McCoy explained that when it was not clear why the dog’s allergies have improved the lung function, once a person becomes sensitive to the dog’s allergy that can make the symptoms of asthma worse.
“This suggests that the dog may prevent sensitization in early contact with allergies, perhaps by changing the nasal microbiome – a mixture of microbes living inside the nose – or some effect on the immune system,” they continued. “Our findings highlight the potential protective role of dog allergies, but we need to do more research to understand the link between dog allergies, lung function and early life contact of asthma during childhood.”
Dr. Errol Galard, the Specialist Group of the European Respiratory Society president asthma and the Associate Professor at the University of Lacester, who was not involved in research, said it was good news for families with a pet dog – but need to know more about the connection and how the children living with pets affect the lungs of the development of children.
“Asthma is the most common long -term condition among children and youth and one of the main causes of hospitalization for children for emergency treatment. However, there are good treatments that can reduce or prevent asthma symptoms, we also want to reduce risk factors to prevent asthma.
“This study suggests that children who grow around dogs may have a low risk of developing asthma. This is potentially good news for pet dogs families; however, we need to learn more about this link and how to stay with pets affect the developing lungs of children in the long term.”
