The-latest-study-on-the-causes-of-asthma-published-in-April-2021
Welcome to Complete Line
In April 2021, Lehigh University published the most recent study on the causes of asthma .
Asthma afflicts more than 300 million people worldwide
Nearly 50% of the children whose asthma is poorly controlled are expected to emerge as severe adult cases .
Asthma has been classified as two major sets of symptoms:
T helper cell high (Th2-high) and T helper cell low (non-Th2)
The non-Th2 type, marked explicitly by being non-allergy-related ,is far less understood than the TH-2 type and could transform into severe or difficult to treat type.
The primary reason for lack of therapeutic and preventive measures is that no cause has ever been identified for the non-Th2 asthma
Now, for the first time, an epidemiological study has shown that it's likely inducer is early childhood exposure to airborne Benzo pyrene, a by product of fossil fuel combustion .
The team tested two comparable groups of children from an industrial city, Ostrava, and the surrounding semi-rural area of Southern Bohemia, in the Czech Republic 194 children with asthma and a control group consisting of 191 children .
According to the study, Ostrava is an industrial city with a high level of coal mining activities ,coal processing, and metallurgical refinement .
The district-level ambient mean for Benzo pyrene was 11-times higher than the recommended outdoor and indoor air quality standard .
Not only was elevated exposure to Benzo pyrene associated with correspondingly elevated odds of non-Th2 asthma, it was also associated with depressed systemic oxidant levels .
Thanks for watching and wait new study every day
