Struggling with Runny Noses Due to Allergies? potential Role of Nose Fungi Could be the Culprit.
Struggling with Runny Noses Due to Allergies? potential Role of Nose Fungi Could be the Culprit.
During the arrival of spring, numerous individuals experience nasal congestion due to seasonal allergies. A group of researchers recently uncovered some noteworthy discrepancies in fungal populations between individuals with such allergies and those without, focusing specifically on the nose.
In a study published on December 17 in the journal Frontiers in Microbiology, an international team of scientists discovered that individuals experiencing allergy-induced sneezing and breathlessness have a diverse and distinct fungal composition in their noses compared to those without symptoms. These findings could pave the way for innovative treatments in the field of allergy and breathlessness research.
Luis Delgado, a researcher from the University of Porto who contributed to the study, stated, "We observed that allergic rhinitis samples displayed significantly higher fungal diversity and a different fungal community structure compared to those of healthy controls." Allergic rhinitis refers to symptoms such as a blocked or runny nose, sneezing, itching, and swollen nasal membranes.
Delgado added, "This may suggest that allergic rhinitis increases the diversity and alters the composition of the upper airway's microbiome." Allergic rhinitis is often linked with asthma, which also involves inflammation and constricted airways. The researchers posited that allergic rhinitis and asthma may be two facets of the same underlying condition.
The research team, involving collaborators from The George Washington University, collected nasal swabs from 215 patients from an immunology and asthma clinic in Porto, Portugal, and 125 healthy individuals. Among the patients, 155 had both allergic rhinitis and asthma, 47 had only allergic rhinitis, and 12 had only asthma.
The researchers then analyzed the fungal DNA obtained from the nasal swabs and reported the detection of common fungi that have been identified as allergens or opportunistic fungal pathogens. Delgado noted, "This confirms, at the fungal level, what is already known for bacteria: that the nasal cavity serves as a significant reservoir for opportunistic fungal pathogens that can cause allergic rhinitis and asthma."
While these fungal pathogens were discovered in all samples, Delgado and his colleagues found that individuals with respiratory diseases had more plentiful and diverse fungal communities in their noses than those without symptoms. Furthermore, the team noted evidence suggesting that the fungi of patients with both respiratory diseases were impacting the nose's immune environment.
Perhaps most significantly, they also found an excess of 5-aminoimidazole ribonucleotide—a chemical compound linked to energy metabolism and DNA synthesis—in the noses of patients with both respiratory diseases. The researchers propose that, with further research, this potential association could direct future therapies towards AIR for diagnosing and treating nasal congestion and breathlessness.
The team plans to conduct additional studies, providing hope to the hundreds of millions of people who frequently reassure their friends that their symptoms are "just allergies" every time they reach for a tissue.
The discovery of diverse and distinct fungal compositions in the noses of individuals with allergy-induced symptoms opens up possibilities for future breakthroughs in allergy and breathlessness research. With the identification of 5-aminoimidazole ribonucleotide in the noses of patients with respiratory diseases, there's potential for developing novel therapies for diagnosing and treating nasal congestion and breathlessness in the future.
Advances in science and technology could significantly contribute to the understanding and management of health conditions like allergic rhinitis and asthma, as they allow for the detailed analysis of fungal DNA obtained from nasal swabs.
