Welcome to this talk,
The Clinical Relevance
of Pollen and
Fungal Spores in
Allergic Diseases.
The narration is by a member of
HSTalks on behalf
of Dr. Rosa Codina,
Director and Principal
Scientist at
Allergen Science & Consulting
in Lenoire, North Carolina.
Additionally, she
holds the position of
Clinical Associate Professor at
the University of South
Florida College of Medicine
in Tampa, Florida.

Today I will cover the
environmental aspects,
biological aspects,
and technical aspects,
including allergenic
extracts for
diagnosis and treatment.

The occurrence of asthma and
allergic rhinitis is widespread
in many regions, globally.
In the United States,
for instance,
the reported prevalence of
these conditions
varies from 10-30%.
Respiratory allergies,
especially in
individuals with
a predisposition,
are significantly influenced by
exposure to fungal allergens.
1:01
Health can be affected by
both chemical and
biological agents.
Non-biological elements, such as
particulate matter,
carbon dioxide,
sulfur dioxide, and ozone, are
monitored for compliance
with legal exposure limits.
Conversely, biological agents,
like pollen and fungal spores,
are primarily monitored
for scientific purposes.
1:22
Traditionally, the
medical community,
especially allergists
or immunologists,
has tended to emphasize
pollen allergy over
fungal allergy.
This emphasis is rooted in
clinical observations and
the routine dissemination of
pollen and spore counts
by monitoring stations.
However, several
factors contribute
to shaping this emphasis
including, one, the greater
complexity of fungi
compared to pollen;
two, variations in
exposure to pollen
and fungal allergens,
and three, the selective
significance of
available pollen
and fungal extracts
for diagnosis and treatment.
