Sensitization to serum albumins in children allergic to cow's milk and epithelia.

Patients with persistent milk allergy and specific immunoglobulin E (IgE) to bovine serum albumin (BSA) have a greater risk of rhinoconjunctivitis and asthma because of animal dander. To prove the cross-reactivity between serum albumin (SA) of different mammals in milk, meat, and epithelia and determine if heat treatment of meats decrease the allergenicity of albumins. The study was performed using SDS-PAGE and IgE-immunoblotting using sera from eight patients sensitized to milk, BSA, and animal danders. Sera from non-allergic and only animal dander allergic subjects served as a control. With one exception, all patients' sera recognized SA in different meats (beef, lamb, deer, and pork), epithelia (dog, cat, and cow), and cow's milk. Some patients even were only sensitized to SA in meat and epithelia. Danders' allergic only recognized other proteins in epithelia but not SA. No patients reacted to SA from heated meat extracts. Serum albumin is an important allergen involved in milk, meat, and epithelia allergy. The first contact with SA was through cow's milk and patients developed sensitization to epithelia SA even without direct contact with animals. Patients with both BSA and cow's milk allergy must avoid raw meats and furry pets.

[Anisakiasis gastrointestinal manifestations: description of 42 cases]. / Manifestaciones digestivas de la anisakiasis: descripción de 42 casos.

BASIS: Anisakiasis is an emerging parasitosis in our environment, although still scarcely known, mainly its gastrointestinal manifestations. PATIENTS AND METHODS: In this paper 42 cases of anisakiasis with gastrointestinal symptoms (with or without cutaneous allergic manifestations) are described; all cases were studied in our hospital between 1995 and May 2004. RESULTS: Thirty seven cases showed a gastric or gastroallergic form (6 confirmed with gastroscopy) and 5 suffered intestinal symptoms. In those in which endoscopy was not carried out, the diagnosis was done after clinical and biological findings. All patients were sensitized in the presence of Anisakis simplex. The 69% (29 cases) described raw anchovies ingestion or anchovies seasoned in vinegar ingestion some hours before the beginning of the clinical picture. The 59% showed allergic symptoms (gastroallergic anisakiasis); no patient with intestinal affectation showed allergic symptoms. Nausea (67%), vomiting (51%), and epigastralgia (50%) were the dominant symptoms in the group with gastric or gastroallergic anisakiasis without endoscopic confirmation; on the other hand, pain in right ileac fossa was the dominant symptom in the intestinal form. Fever was seen in two of the later patients (40%), but in no patient with gastric or gastroallergic anisakiasis. CONCLUSIONS: Gastrointestinal symptomatology after ingestion of fish suspiciously prepared should suggest anisakiasis, regardless if clinical picture includes allergic manifestations. In our study, pain in right ileac fossa, fever, and absence of allergic manifestations were typical of intestinal form.

Manifestaciones digestivas de la anisakiasis: descripción de 42 casos / Anisakiasis gastrointestinal manifestations: description of 42 cases

Fundamento. La anisakiasis es una parasitosis emergente en nuestro medio, aunque todavía escasamente conocida, principalmente en sus manifestaciones digestivas. Pacientes y métodos. Se describen 42 casos de anisakiasis con afectación digestiva (con o sin manifestaciones alérgicas cutáneas) estudiados en nuestro hospital entre 1995 y mayo de 2004. Resultados. Treinta y siete casos mostraban una forma gástrica o gastroalérgica (6 confirmados mediante gastroscopia) y 5 manifestaciones intestinales. En aquellos en que no se realizó endoscopia el diagnóstico se efectuó tras los hallazgos clínicos y biológicos. Todos los pacientes estaban sensibilizados frente a Anisakis simplex. El 69% (29 casos) referían ingesta unas horas antes de anchoas en vinagre o crudas. El 59% presentó clínica alérgica asociada (anisakiasis gastroalérgica), no presentando esta clínica ninguno de los casos con afectación intestinal. Las náuseas (67%), vómitos (51%) y epigastralgia (50%) fueron los síntomas dominantes en el grupo con anisakiasis gástrica o gastroalérgica sin confirmación endoscópica, mientras que el dolor en fosa ilíaca derecha lo fue en la forma intestinal. Dos de estos pacientes (40%) presentaron fiebre, aunque ninguno de los casos con anisakiasis gástrica o gastroalérgica. Conclusiones. La aparición de sintomatología digestiva después de la ingesta de pescado preparado de forma sospechosa debe hacer pensar en una posible anisakiasis, independientemente de que se asocien o no manifestaciones alérgicas. La presencia de dolor en fosa ilíaca derecha, fiebre y la ausencia de manifestaciones alérgicas fueron característicos de las formas intestinales

Pólenes alergénicos y polinosis en la ciudad de Burgos / Allergenic pollens and pollinosis in the city of Burgos

El objetivo de este estudio ha sido conocer cuáles son los pólenes que con más probabilidad producen polinosis en el área de la ciudad de Burgos. Método: Para ello se realizaron recuentos de pólenes con un colector Burkard, situado en la terraza del hospital General Yagüe. Se analizaron los taxones cuya media fuera superior al 1% del total de los años 1997, 1998 y del 2001 al 2004. Dentro de un estudio multicéntrico del Comité de Aerobiología de la SEAIC para el estudio de la polinosis, se seleccionaron 147 pacientes de ambos sexos, con clínica de rinitis, asma o ambas estacionales, residentes en nuestra área y con pruebas positivas frente a pólenes. Según el método de estudio se realizaron pruebas cutáneas por la técnica del prick con una batería de 25 pólenes. Resultados: Los pólenes alergénicos más frecuentemente encontrados en la atmósfera de Burgos fueron: cupresáceas (38,87%), especies de Quercus (14,51%), gramíneas (13,58%), especies de Pinus (10%), especies de Urtica (4,74%), especies de Platanus (3,49%), especies de Plantago (3,32%), Populus (2,26%), Olea (2,20%) y chenopoidaceas-amarantaceas (1,26%). Comparado con los pólenes anteriores, los resultados de las pruebas del prick en orden de prevalencia fue: gramíneas (91%), Plantago lanceolata (42,86%), Olea europaea (36,05%), Chenopodium album (26,53%), Urtica dioica (24,49%), Platanus hispanica (21,77%), Cupressus arizonica (19,05%) y Quercus ilex (18,37%). Como se observa en nuestros resultados, la sensibilización frente al polen de las gramíneas es la causa principal de polinosis en nuestro medio

The aim of the study was to know the main pollens with a higher probability of inducing pollinosis in the city of Burgos. Methods: For this purpose, pollen levels were measured by a Burkard collector situated in the terrace of the General Yagüe’s Hospital. Taxons with a mean above 1% of total during 1997, 1998 and 2001-2004 were analyzed. As part of a multicentric study from the SEAIC’s Aerobiology Committee for the study of pollinosis, 147 patients of both sexes with symptoms of seasonal rhinitis and/or asthma, resident in our area and with positive tests to pollens were selected. According to the study’s methodology, prick tests were performed with a panel of 25 pollens. Results: The allergenic pollens more prevalent in the atmosphere of Burgos were: cuppressus (38.87%), Quercus spp (14.51%), grasses (13.58%), Pinus spp (10%), Urtica spp (4.74%), Platanus spp (3.49%), Plantago spp (3.32%), Populus (2.26%), Olea (2.20%) y Chenopoidaceae- Amarantaceae (1.26%). Comparing with previous pollens, the results of prick tests were in order of prevalence: grass (91%), Plantago lanceolata (42.86%), Olea europaea (36.05%), Chenopodium album (26.53%), Urtica dioica (24.49%), Platanus hispanica (21.77%), Cupressus arizonica (19.05%) and Quercus ilex (18.37%). As we can infer from our results, sensitization to grass pollens constitutes the major cause of pollinosis en our area
