Sucking the baby's nap can protect them from allergies, says the study

DENVER – Your child’s nap falls on the floor. Before leaving it back to your child, do you wash it in a sink or perhaps reluctantly, clean it with your own regret?

Do not feel guilty if you choose the latter because a new study suggests that a mother’s spit and bacteria in it can help prevent allergies in toddlers.

The research found lower levels of an aggressively allergic protein in infants whose mothers reported that they said on their infant’s stimulants and allowed a growing body of evidence that early exposure to microbes could prevent allergies in children.

“The idea is that the microbes exposed to infants can affect the development of your immune system later in life,” says Dr. Eliane Abou-Jaoude, an allergist to the Henry Ford Health System in Detroit.

Microbial exposure can prevent allergies

Research has shown that people living close to cattle, those living near the cattle that avoid dishwashers and infants born through the microvaginal vaginal canal &#821

The new study, which has not been reviewed, is “an additional piece of data that early exposure to microbes helps prevent allergies,” said Dr. Andrew MacGinnitie, Clinical Director of Immunology Department at Boston Children’s Hospital.

But the study also has weaknesses, MacGinnitie said. It has a small sample size, which makes it difficult to draw too many conclusions, and other factors than the mother’s saliva could have helped to develop the children’s immune system.

“It is possible to suck on a nap is correlated with other, more important factors that predispose or protect against allergens,” he said, adding that mothers sucking on their children’s pacifiers could also “let their children play in the dirt, or The whole house may be less clean. “

Uncertainty about causal relationship is why Abou-Jaoude does not recommend that parents start to suck on their children’s pacifiers yet.

“It is very important to realize that this was not a cause and effect study,” she said. “This does not tell you if you suck on your child’s pacifier, they will not develop allergies.”

For those who choose to do that, MacGinnitie does not look too many risks. “If the child was ill, he or she could send an infection to mother or father, but if the child is good then it seems unlikely,” he said.

And although the nap falls on the floor, he added, “generally, the bacteria and the virus on the floor do not cause diseases.”

A Reduction Of Allergic Related Proteins

To determine allergy risks, the researchers searched for a protein linked to allergies. The traced levels of that protein, the IgE antibody, in 74 infants whose mothers reported using pacifiers. No fathers participated in the research.

Only nine children had mothers who sucked their children’s binkies clean. However, compared to the other children, the nine children had significantly lower levels of IgE antibodies, a trend that began when the children were about 10 months old.

The researchers tracked the children for only 18 months, making it unclear whether lower IgE levels in infants would be translated into fewer allergies later in life.

“Based on these levels, you can not really tell what will happen to these children in the future,” said Abou-Jaoude. “All we know is, people with allergies, they usually have higher levels of IgE antibodies. But that does not mean that if you have high IgE, you will definitely have allergies.”

Our bodies develop antibodies to infections, but MacGinnitie says that IgE antibodies are often produced in response to harmless substances – which is why they are closely associated with allergies.

“Allergies are an inappropriate response from our immune system to see something harmless as dangerous,” he said, leading to congestion, nasal congestion and other common symptoms.

Reduce Your Child’s Allergy

The Abou-Jaoudes team looked at total IgE antibody levels, but researchers can also test for allergen specific IgE levels and look at how sensitive a child may be to certain subjects, like eggs or dogs.

A 2013 study in Sweden did just that. Not only did researchers find that infants were less likely to have IgE antibodies to common allergens when their parents told their pacifiers, but they were also less likely to develop eczema and asthma at the time they were 18 months.

“If I understood the paper and the figure correctly, [the new study] found lower IgE levels in children whose parents reported to suck their nappes, and that support supports our results,” said Dr. Bill Hesselmar, Associate Professor of Pediatrics at the University of Gothenburg.

In both cases, Hesselmar says that sucking on a child’s pacifier may have transmitted “microbes that can stimulate the immune system to develop tolerance instead of allergy.”

Still, it is more practical – and perhaps more pleasant – MacGinnitie said that early exposure to certain foods could protect against allergies.

Studies have shown that “children introduced into peanuts during the first year of life have a much lower chance of developing a peanut allergy,” he said. , and the American Academy of Pediatrics agrees. In 2017, the group adopted guidelines recommending that high-risk children for allergies should jar eat peanuts as early as 4 to 6 months.

Children who grow up with pets also tend to have a lower allergy, said MacGinnitie, but can be explained by genetics. In other words, allergy-free parents who own pets can only feed children with allergy.

“Living on a small farm probably also helps,” laughed MacGinnitie. But he added that to most parents, “that’s probably not realistic.”
