Immunoglobulin E-binding reactivities of natural pollen grain extracts from selected grass species in the Philippines.

Cabauatan CR, Ramos JD - Asia Pac Allergy (2012)

Bottom Line: Pollen grains have been reported to be present in the Philippine atmosphere but studies regarding their allergenicity are limited.Sensitization of the allergic individuals to the pollen extracts was detected with I. cylindrica and O. sativa to be the most frequently recognized with more that 92% reactivity, whereas for C. dactylon and Z. mays, were found to have less than 25% reactivity.Multiple IgE-binding proteins from S. indicus, S. spontaneum and C. barbata that were detected may be responsible for the allergic reactions among Filipino subjects.

ABSTRACT

Background: Pollen grains have been reported to be present in the Philippine atmosphere but studies regarding their allergenicity are limited.

Objective: The present study aimed to profile the sensitization of allergic individuals to selected grass pollen species and to characterize the pollen proteins that may be responsible for this allergenic response.

Methods: The protein profile of the grass pollen extracts from Cynodon dactylon, Saccharum spontaneum, Sporobulus indicus, Chloris barbata, Oryza sativa, Imperata cylindrica, and Zea mays was analyzed by Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis. The specific-IgE profile of the allergic individuals and the allergenic potential of the pollen extracts were evaluated through Enzyme-linked Immunosorbent Assay and IgE immunoblotting.

Results: Sensitization of the allergic individuals to the pollen extracts was detected with I. cylindrica and O. sativa to be the most frequently recognized with more that 92% reactivity, whereas for C. dactylon and Z. mays, were found to have less than 25% reactivity.

Conclusion: Multiple IgE-binding proteins from S. indicus, S. spontaneum and C. barbata that were detected may be responsible for the allergic reactions among Filipino subjects.

Figure 1: Sex distribution of subjects according to their allergic symptoms.

Mentions: The 141 subjects had an age range of 3 to 79 years, the population had a mean of 26.4 years and 20.9 years standard deviation. Fig. 1 show that 36% of the subjects suffered from dermatitis, 34% had asthma, and 16% had rhinitis. The rest of the subjects were with conjunctivitis and with a combination of 2 or more of the allergic symptoms. Female subjects had higher preponderance than male having a ratio of 2:1 (female:male). No significant values with respect to gender and symptom were present.
