The concentration of allergens at an increased place leads to asthma

The results of a national survey have demonstrated that high levels of allergens in the home are linked to symptoms in asthma patients. Research shows that allergic asthma patients can reduce asthma symptoms by reducing the occurrence of allergens in their homes. The investigation was conducted by the Environmental Health Council (NIEHS), the Rho Inc company of the University of Iowa, and Constella's group. The results may help millions of Americans suffering from asthma.

' The presence of allergens in the home is an important factor in the connection to asthma because most people use most of their time in the home, especially the accommodation ,' according to Darryl Zeldin - Investigator of the respiratory biology laboratory at NIEHS and the author has a long history of many articles.

Asthma is one of the most common chronic diseases in the United States, affecting more than 22 million people. Asthma is driven by many substances called allergens.

The results of the study are published online and in March, Allergy & Clinical Immunology shows that the presence of many allergens in the United States is normal: 52% of families have little Most 6 allergens were found and 46% had 3 or more allergens with elevated levels. The investigated allergens in the home include elements from dogs, cats, mice, cockroaches, dust and fungus Alternaria.

The study used data from the national survey on lead levels and household allergens (NSLAH) to examine the factors contributing to the increase in the concentration of agents. allergens and determine if high concentrations in households are related to the asthma status of occupants. NLSAH, the first national survey describing the presence of different allergens among households, studied the housing of nearly 2500 people in 75 locations across the United States. The investigation was co-financed by NIEHS and the United States Urban Development Commission.

A number of factors have been found to contribute to the increase of allergens, including race, income, family type, allergy source, such as the presence of pets or offensive objects. . The study also found that families with children tend to have lower levels of allergens. Regular home cleaning is a simple and effective solution to reduce the current situation.

According to NIEHS researcher Paivi Salo, the study provided useful information for asthma patients.'The results we find emphasize the importance of reducing the occurrence of allergens, which is a fundamental part of asthma control,' she said. 'Although it is not possible to turn a place into a place with absolutely no allergens, asthma patients with allergies must be more active in reducing the level of allergens in their families to enhance their ability to asthma control '.

This is the first study to provide information on the total allergen concentration in households in the United States and its relevance to asthma.'This study confirms that allergens in the home play an important role in asthma,' Zeldin said.

However, Salo and co-authors point out that additional studies are needed to understand the complex relationship between genetics and environmental triggers for asthma, especially the role of Allergic agents in the development of asthma. 'Although reducing the level of allergens cannot prevent individuals from having asthma, it is crucial for people with asthma to have a natural allergy nature' Zeldin concluded.
