“…However, cockroach sensitization was the most important indoor allergen in our area. The prevalence of cockroach sensitivity in this study seems to be lower than that reported in the atopic population of some US cities (7), but similar to that reported in other European cities (9,10,17,18).…”

“…Previous studies have established that cockroach allergens are important sensitizing agents in the induction of rhinitis and asthma (1-8 (2,3,6). However, in Europe, this prevalence seems to be lower; for example, in a Swiss population with rhinitis and asthma, only 6.3% of the patients were sensitized (9) and only 24.5% in a population in Marseille, France (10). Previous studies in Spain have shown a prevalence of positive skin tests to cockroach ranging from 15% (11) to 29% (12) of asthmatic patients, but this is the first study to include four different cockroach extracts.…”

Previous studies have established that cockroach allergens are important sensitizing agents in the induction of rhinitis and asthma principally in urban areas. This study was undertaken to assess skin test reactivity and specific IgE antibody reactivity to extracts of Periplaneta americana (P.a.), Blattella germanica (B.g.), B. orientalis (B.o.), and a fecal extract of B. germanica (FEB.g.) in a group of patients with rhinitis and asthma living in an urban area in Europe. We examined clinical characteristics and aerollergen sensitivities of 171 consecutive Madrid urban patients with rhinitis and asthma who met the criteria for the study. A comprehensive clinical evaluation was followed by skin prick test with common allergens and saline extracts of P.a., B.g., B.o., and FEB.g. and measurement of serum specific IgE antibody to cockroach extracts. The age of patients ranged from 7 to 68 years (mean 20.4 +/- 16). A total of 153 (90.5%) subjects were atopic and 19 (10%) were considered nonallergic. Pollen sensitivity (66.5%) was most prevalent, distantly followed by sensitivity to cockroach (25.7%), mite (20%), cat (15.5%), Alternaria alternata (14.5%), dog (14%), and food (2%). Skin test reactivity to cockroach extracts was 37 (21.6%) to B.o., 20 (11.6%) to P.a., 19 (11.1%) to B.g. and five (2.9%) to FEB.g. Twenty-one of these patients had rhinitis, 19 rhinitis and asthma, and one only asthma; 26 had perennial symptoms, while 16 had seasonal (spring) symptoms; three (1.7%) patients had only positive prick test to cockroach; all had perennial rhinitis and/or asthma. Eighteen (10.5%) patients had specific serum IgE (RAST 1 or 2) to B.o., 13 (7.6%) to P.a., and six (3.5%) to B.g. Eighty (46.7%) patients had visual evidence of cockroach infestation in their home, mostly B.o.; 31 had positive prick test to cockroach (P < 0.0003). The results indicate that sensitivity to outdoor allergens (pollen) is more prevalent than to indoor allergens. Cockroach sensitization is the most important indoor allergen in our area, and B.o. accounts for most cockroach sensitization.

Group 10 allergens (tropomyosins) have been assumed to be a major cause of cross-reactivity between house-dust mites (HDMs) and other invertebrates. Despite all of the published data regarding the epidemiology, percent IgE binding and level of sensitization in the population, the role of tropomyosin as a cross-reactive allergen in patients with multiple allergy syndrome still remains to be elucidated. Homology between amino acid sequences reported in allergen databases of selected invertebrate tropomyosins was determined with Der f 10 as the reference allergen. The 66.9 and 54.4% identities were found with selected crustacean and insect species, respectively, whereas only 20.4% identity was seen with mollusks. A similar analysis was performed using reported B-cell IgE-binding epitopes from Met e1 (shrimp allergen) and Bla g7 (cockroach allergen) with other invertebrate tropomyosins. The percent identity in linear sequences was higher than 35% in mites, crustaceans, and cockroaches. The polar and hydrophobic regions in these groups were highly conserved. These findings suggest that tropomyosin may be a major cause of covariation of sensitization between HDMs, crustaceans, and some species of insects and mollusks.
