As our understanding of the nasal microbiome evolves, maintaining a balanced microbial environment in the nose may prove important in the management and prevention of respiratory conditions such as allergic rhinitis and asthma.

An unprecedented study conducted in Portugal has shown that these conditions may be linked to distinct fungal communities, or mycobiomes, in the nose, providing new insights into their development and potential treatment strategies. Led by Dr Luis Delgado of the University of Porto, the research published in Frontiers in Microbiology analyzed nasal fungal communities in 214 participants, including: 155 with both allergic rhinitis and asthma. 47 With rhinitis only.

12 With asthma. 125 healthy individuals as a control group.

Allergic rhinitis causes sneezing, itching and runny nose and is caused by an overreaction of the immune system to allergens such as dust, pollens and fungi, while asthma is a chronic respiratory condition that inflames and narrows the airways, making it difficult to breathe. It can cause coughing, wheezing, and chest tightness, especially during flare-ups.
