Researchers in Switzerland said that the accumulation of allergies in childhood may increase the risk of psychological problems and chronic infections caused by infections.
Researchers at the University of Zurich in cooperation with colleagues at the University of Lausanne have shown that differences in the human immune system already appear in childhood and remain characteristic as they grow older. A researcher at the University of Zurich and the University Hospital in Lausanne found that there is a connection between childhood diseases. In childhood and susceptibility to disease later.
The researchers, under the supervision of Vladima Eideschich Gross of the University of Zurich, analyzed data related to the epidemiological effects of about 5,000 people born in the mid-twentieth century.
The researchers used the history of these patients in their infancy, dividing them into five groups, the University of Zurich reported on Monday.
The researchers said in a statement that the ward was based on vital signs such as white blood cells and symptoms of inflammation, and then researchers developed these childhood patterns regarding chronic inflammation diseases and mental illnesses in adult life.
The researchers published the results of their study in the current issue of the BMC Medsine Journal of Medical Studies.
Allergies and mental illnesses make people vulnerable to illness.
The researchers found a relationship in three of these groups between childhood disease patterns and subsequent susceptibility of people to mental illness.
One of the three groups was the allergy group, which included 7% of these people, with various types of allergies, the second group was "mixed" and included 9%. The owners had different types of allergies and diseases. Childhood, such as scarlet fever, whooping cough or measles, and the group "psychological injuries", which exposed the owners of childhood under great psychological pressure. The researchers found that patients in the third group were more susceptible to allergies, but were relatively more resistant to viral diseases.
All three groups were also more likely to develop chronic inflammatory diseases, while the high risk of psychiatric damage was limited only to women, the researchers said.
The largest group, which includes 60% of the people examined, has an abnormally "neutral" immune system with relatively little exposure to childhood illnesses, and the second largest group, which includes about 20% of people with a strong immune system ( MRNA), where the incidence of measles and atopic diphtheria, which had no vaccination at the time, was lower than that of the "neutral" group.
According to the study, the flexible members of the group were the best protection in adulthood, both against mental injuries and chronic infections.
"This helps us understand why many people who have never been psychologically stressed have been affected by psychological illnesses," said Aydeshish Gross. On the other hand, people who have suffered from mental illness tend to have chronic inflammatory diseases. "
Other analyzes compared the overlapping of parts of the aforementioned groups over time. The flexible immune system group has a higher proportion of babies in the early years than the young, while youngsters in that group have increased the proportion of allergic groups.
– The study confirms the theory of cleanliness.
This finding also confirms what is known as "hygiene theory," whose authors argue that better hygiene and greater mobility of rural life and city life have increased the susceptibility of the population.
According to this theory, the human immune system is exposed to increasingly smaller microbes during childhood if the child is born in the city while being more exposed to microbes if he grew up on a farm, for example.
By interacting with these microbes, the human immune system learns to deal adequately with these pathogens, and the origin is harmless.
