“…The prevalence of current rhinoconjunctivitis in adolescents varied 5-fold (from 8.9% in São Paulo West [Brazil] to 45.1% in Asuncion [Paraguay]) and 3.7-fold for the 6-7-year-old children (from 5.5% in Rosario City [Argentina] to 20.4% in Caracas [Venezuela]) (Table 2). 31…”

Asthma and rhinitis epidemiology has wide variations around the world. The aim of this review was verify the prevalence of asthma and rhinitis in South America and report differences from other regions of the world. We reviewed studies with International Study of Asthma and Allergies in Childhood (ISAAC) methodology in South America, Phases I and III. In South America the ISAAC Phase I ranked four countries among top ten in prevalence of asthma and three countries among top ten in prevalence of rhinoconjunctivitis. ISAAC Phase III showed little changes in asthma and rhinitis prevalence in South American countries. The prevalence increases of asthma and rhinitis in South American centers indicate that the burden of both is continuing to rise, but the differences in prevalence are lessening.

“…These characteristics together with the varying altitude divide the country according to the National Geographic Institute ( Instituto Nacional de Estadística y Geografía , INEGI) in six climate zones [6]. The ISAAC studies found a prevalence of rhinitis in Mexican children between 11.6-15.4% and asthma-like symptoms between 8.5-15.6% [1,7,8]. Allergic rhinitis risk factors and economic impact have been documented in that country [9,10].…”

BackgroundAllergen exposure leads to allergen sensitization in susceptible individuals and this might influence allergic rhinitis (AR) phenotype expression. We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age.MethodsIn a national, cross-sectional study AR patients (2-70 y) seen by allergists underwent blinded skin prick testing with a panel of 18 allergens and completed a validated questionnaire on AR phenotypes.Results628 patients were recruited. The major sensitizing allergen was house dust mite (HDM) (56%), followed by Bermuda grass (26%), ash (24%), oak (23%) and mesquite (21%) pollen, cat (22%) and cockroach (21%). Patients living in the tropical region were almost exclusively sensitized to HDM (87%). In the central agricultural zones sensitization is primarily to grass and tree pollen. Nationwide, most study subjects had perennial (82.2%), intermittent (56.5%) and moderate-severe (84.7%) AR. Sensitization was not related to the intermittent-persistent AR classification or to AR severity; seasonal AR was associated with tree (p < 0.05) and grass pollen sensitization (p < 0.01). HDM sensitization was more frequent in children (0-11 y) and adolescents (12-17 y) (subtropical region: p < 0.0005; tropical region p < 0.05), but pollen sensitization becomes more important in the adult patients visiting allergists (Adults vs children + adolescents for tree pollen: p < 0.0001, weeds: p < 0.0005).ConclusionsIn a country with (sub)tropical climate zones SPT sensitization patterns varied according to climatological zones; they were different from those found in Europe, HDM sensitization far outweighing pollen allergies and Bermuda grass and Ash pollen being the main grass and tree allergens, respectively. Pollen sensitization was related to SAR, but no relation between sensitization and intermittent-persistent AR or AR severity could be detected. Sensitization patterns vary with age (child HDM, adult pollen). Clinical implications of our findings are dual: only a few allergens –some region specific- cover the majority of sensitizations in (sub)tropical climate zones. This is of major importance for allergen manufacturers and immunotherapy planning. Secondly, patient selection in clinical trials should be based on the intermittent-persistent and severity classifications, rather than on the seasonal-perennial AR subtypes, especially when conducted in (sub)tropical countries.

“…En el caso de Colombia, múltiples estudios demuestran un posible incremento en la prevalencia de las mismas (5)(6)(7). Entre el 5% y el 15% de los lactantes muestran síntomas sugestivos de reacciones adversas a las PLV, mientras que las estimaciones de la prevalencia real de la APLV varían del 2% al 7,5%, cifras que van en aumento en todos los países (8).…”

Introducción: La alergia a la proteína de leche de vaca (APLV) es la alergia alimentaria más frecuente en el primer año de vida. La evidencia actual acerca de la respuesta a una fórmula extensamente hidrolizada a base de suero es insuficiente.Objetivo: Determinar los desenlaces clínicos en lactantes con APLV a una fórmula extensamente hidrolizada a base de suero (Nutrilón Pepti Junior®).Metodología: Estudio retrospectivo, tipo serie de casos. Se incluyeron lactantes (≤ 12 meses) con APLV valorados en la consulta externa entre enero de 2011 y octubre de 2015 en un servicio de gastroenterología pediátrica. La información de datos demográficos, manifestaciones digestivas, tiempo de inicio de síntomas, antropometría y respuesta clínica a la fórmula fue abstraída a partir de la revisión de la historia clínica. Se comparó el estado nutricional de los pacientes en la primera y en la consulta de control un año después utilizando la prueba t de student.Resultados: Se incluyeron 40 lactantes (42,5% varones), edad: 3,3±2,4 meses, con síntomas de: vómito/regurgitación, cólico/irritabilidad y deposición con sangre. Los antecedentes familiares y perinatales relacionados con el desarrollo de APLV fueron: ingesta de biberón en la primera semana de vida: 27 (67,5%), madre ≥ 30 años: 33 (82.5%), atopia en 2 familiares: 12 (30%) y parto por cesárea: 30 (75%). 37 (92,5%) pacientes mostraron una respuesta positiva a una fórmula extensamente hidrolizada a base de suero, mientras que 3 (7,5%) pacientes no respondieron y requirieron una fórmula a base de aminoácidos libres. Los z-score de P/E: -0,69±1,03 y P/T: -0,79±1,00 de la primera consulta mejoraron en el seguimiento posterior al año (p < 0,05): P/E: -0,27±0,98 y P/T: -0,14±0,98.Conclusión: Se encontró recuperación nutricional y tolerancia a la leche de vaca en un alto porcentaje de lactantes con APLV que recibieron una fórmula extensamente hidrolizada a base de suero.
