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

Do not feel guilty if you choose the latter because a new study suggests that a mother’s saliva – and its bacteria – can help prevent allergies in small children.

The research found lower levels of an aggressive allergenic protein in infants whose mothers reported sucking on their infant pacifiers and adding a growing evidence that early exposure to microbes can prevent allergies in children.

“The idea is that the microbes exposed to infants can affect your immune system development later in life,” said Dr. Eliane Abou-Jaoude, an allergy company with the Henry Ford Health System in Detroit. She presents her results this weekend at the American College of Allergy, Asthma and Immunology Annual Scientific Meeting.

Research has shown that people living close to cattle, those who avoid detergents and infants born through the microwaved vaginal canal ̵

 Bacteria swabbing trend for newborn medical doubtful

The new study, which has not been reviewed, is “additional data exposed to microbes to help prevent allergies” , says Dr. Andrew MacGinnitie, Clinical Director of Immunology at the Boston Children’s Hospital.

But the study has sva “said MacGinnitie. 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 that “in general, 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.

 Ah-choo! These meds linked to higher allergic risk in children

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, which makes 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 happens to these children in the future,” said Abou-Jaoude. “All we know is that people with allergies 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 fight infections, but MacGinnitie said that IgE antibodies are often produced in response to harmless substances. That’s why they is 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.

Decreases Your child’s allergy

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

 What causes allergies?

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

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

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 nicer – ways To prevent allergies in children MacGinnitie said that early exposure to some foods, for example, can protect against allergies.

Studies have shown that “children are 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 began to approve guidelines recommending that high risk f r allergies start to 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 it 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.”
