Sucking your baby's pacifier could be protected from allergy, says study


Your baby's pacifist falls on the floor. Before giving it back to your child, do you wash it in a sink or, perhaps reluctantly, clean it with your own saliva?

Do not feel too convicted if you chose the latter, because a new study suggests that mammal spill – and the bacteria – can help prevent allergy in young children.

The research found lower levels of troublesome protein, which cause allergy among babies whose mothers say they suck on their baby pacifiers, adding to an increasing body of evidence that early exposure to preventing microbes allergies in children

"The idea is that the microbes you are exposed during babies can affect the development of your immune system later in life," said Dr. Eliane Abou-Jaoude, allergy with Henry Ford's Health System in Detroit. She presents her perceptions this weekend at the Annual College of Allergy, Asthma and American Immunology Science.

Allergies could prevent allergies

Research has shown that people living close to livestock, those who avoid dishwashers and babies born through the maple canal have been filled by microbial – rather than through section C – all are less likely to develop allergies.

The new study, which has not been reviewed by peers, is "one piece of data that has an early exposure to microbes helping to prevent allergies," said Dr Andrew MacGinnitie, the clinical director of the Immunology at Boston Children's Hospital.

But the study also has weaknesses, says MacGinnitie. It has a small sample size, making it too difficult to draw too many collections, and factors other than saliva and mother may have helped develop children's immune systems.

"Packing sucking may be correlated with other factors, which are more important than precursors or protect against allergens," he says, adding that mothers could which sucks on those who also pack their children "let children play in the dirt, or their whole house could be less clean."

Uncertainty about causing is why Abou-Jaoude does not recommend that parents start sucking their children's accompaniment again.

"What's really important to realize is that this was not a case study and an impact," he said. "This does not tell you, if you're sucking your child's pacifier, they will not develop allergies."

For those who choose to do that, however, MacGinnitie does not see too many risks. "If the child was ill, he or she could transfer an infection to the mother or father, but if the child is good, it seems that this was not unlikely," he said.

And even if the pacifier falls on the floor, he added, "in general, the bacteria and viruses on the floor do not cause a disease."

Reduction in allergies related to proteins

To determine the risk of allergy, researchers looked at an allergic-related protein. They track the levels of that protein, the IgE adventure, in 74 babies whose mothers report using pacifiers. No fathers were included in the research.

Mothers who just sucked their children's binkies were only nine babies. But compared to the other children, the nine babies had lower levels of IgE antibodies, a tendency that began when the children were about 10 months old.

The researchers tracked the babies for only 18 months, making it unclear whether lower IgE levels during babies would translate into fewer allergies later in their lives.

"Based on these levels, you can not say what these children will happen in the future," said Abou-Jaoude. "We all know that, people with allergies, usually have higher levels of IgE antibodies, but that does not mean if you have a high IgE, you 're sure to have an allergy. "

Our bodies develop antibodies to fight infections, but Macinnitie said that IgE antibodies are often produced in response to harmful substances – that is why they are closely related to allergies.

"Our aluminum is an inappropriate response from our immune system to see something that is innocent as dangerous," he said, leading to congestion, bees and other common symptoms.

Reduce your child's allergy risk

The Abou-Jaoude team looked at the total levels of IgE antibodies, but researchers can also experience IgE specific to allergens, looking at the sensitivity of a child to certain substances, such as eggs or dogs.

That was just the 2013 study in Sweden. Not only did researchers find that babies were less likely to have IgE antibodies against ordinary allergens when their parents sucked their pacifiers, but were also less likely to develop eczema and asthma as they were 18 months old.

"If I understand the paper and figure correctly, [the new study] have found lower IgE levels in children whose parents say they suck on their pacifier, and that they find support our results, "said Dr. Bill Hesselmar, a pediatric link teacher at the University of Gothenburg who overseen the study that.

In both cases, Hesselmar says that he could suck a baby pacifist to transfer "microbes that could stimulate the immune system so that tolerance is developing rather than allergy."

Still, there is more practical – and perhaps more desirable – ways of preventing allergy in children. MacGinnitie said that some foods may have an early exposure, for example, against allergies.

Studies have shown that "children introduced to peanuts during the first year of life have much less chance of developing peanut allergy," he said, and the American Pediatric Academy agrees. In 2017, the group approved guidelines that recommended that high-risk allergies begin to eat nuts as early as 4 to 6 months.

Children who grow up with pets also tend to have a lower allergy risk, said MacGinnitie, but genetics could explain that. In other words, parents who have an allergy that do not own pet animals could give birth to allergic children.

"It's likely that living on a small farm will help," said MacGinnitie. But he added, for most parents, "that's probably not that realistic".
