Prevalence of allergic sensitization to regional inhalants among allergic patients in Jakarta, Indonesia.
Sensitization towards a panel of eight regional inhalant allergens was evaluated among 107 patients with allergic rhinitis and/or asthma. A total of 32 children (age 5-13 years, mean 9 years; 18 male, 14 female), 75 adolescents and adults (aged 14-66 years, mean 32 years; 21 male, 54 female) and 20 normal control volunteers (aged 16-46, mean 30 years; 4 male, 16 female) were evaluated via skin prick test. A weal response of 3 x 3 mm or greater was taken to be positive. The sensitization rates among individuals to these allergens were: house dust mites, Dermatophagoides pteronyssinus (77.57%), Blomia tropicalis (71.96%), Austroglycyphagus malaysiensis (33.64%), pollen, palm oil Elaeis guineensis (22.43%), Acacia auriculiformis (12.15%), fern spore, resam Dicranopteris spp (11.21%), fungal spores: Curvularia fallax (8.41%) and Exserohilum rostratum (13.08%). There were significantly higher frequencies of sensitization to these allergens among allergic individuals compared to normal controls, and among atopic individuals with two allergy manifestations (rhinitis and asthma) compared to those with only one. No difference was noted between children and adults in the allergic group. In conclusion, the allergic patients were highly sensitized to dust mites and sensitization to regional pollen and spores was also documented. They should be considered as relevant and be included in skin test batteries in Indonesia.
