Background: Asthma is not well investigated in equatorial Africa and little is known about the disease-associated allergen molecules recognized by IgE from patients in this area. The aim was to study the molecular IgE sensitization profile of asthmatic children and young adults in a semi-rural area (Lambaréné) of an equatorial African country (Gabon), to identify the most important allergen molecules associated with allergic asthma in equatorial Africa.
Methods: Fifty-nine asthmatic patients, mainly children and few young adults, were studied by skin prick testing to (Der p), (Der f), cat, dog, cockroach, grass, Alternaria and peanut.
