Rationale:

Allergy and Asthma cases have doubled in the Texas Panhandle area since 2007 (Ref. Amarillo Globe News, 2011). Analysis of aeroallergen can help in diagnosis and treatment of allergic rhinitis.

Methods:

Analyzing the aeroallergens with a Burkard Spore Trap provided information regarding the onset, duration, and severity of the pollen season that clinicians use to guide allergen selection for skin testing and treatment. We have been investigating the daily aeroallergen concentration in terms of the meteorological conditions such as daily temperature, wind speed and precipitation. We used a Burkard Volumetric Spore Trap to determine the daily aeroallergen index by collecting aeroallergen samples and characterizing them with digital, fluorescence and Scanning Electron Microscopy for 16 years.

Results:

The most significant aeroallergens recorded were the pollens from Asteraceae, Chenopodiaceae, Poaceae and spores from Alternaria, Stachybotrys, Aspergillus and Curvularia. There was a significant correlation between the cases of allergic rhinitis with the aeroallergen concentrations. Precipitation plays a very important role. With plenty of rainfall (2015) aeroallergen index went up and so as the patients' visits to the clinic.

Conclusions:

Environmental factors contribute to a high concentration of aeroallergen that led to the increased allergy cases among the residents of Texas Panhandle.
