Epidemiology of ocular allergy and co-morbidities in adolescents

Epidemiology of allergic conjunctivitis

“…In a recent study [5] conducted in Brazil, the prevalence of ocular allergies symptoms, comorbidities, and their impact in adolescents was studied in 13-and 14-year-old children using a modified ISAAC questionnaire which included eight items on ocular symptoms. Allergic conjunctivitis diagnosis was considered when more than three episodes of ocular itching were reported in the previous 12 months.…”

“…For example, in the United States [4], the prevalence of ocular allergies was calculated considering the third National Health And Nutrition Examination Survey (NHANES III) performed in from 1988 to 1994. The prevalence of ocular allergies symptoms, comorbidities, and their impact on adolescents were studied in a cross-sectional study [5] conducted in 2009 in Brazil, delivering an International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire to more than 3000 students. A different approach was used in a survey among ophthalmologists and general medical practitioners from nine countries in Eastern Europe and the Middle East to estimate the percentage of patients presenting with a red eye [6].…”

Aplicações práticas de uma plataforma multiplex para detecção de IgE específica por componentes alergênicos em doenças alérgicas

“…Além do acometimento frequente das vias aéreas inferiores, estima-se que mais da metade dos pacientes com RA apresentem sintomas oculares compatíveis com conjuntivite alérgica, embora frequentemente o quadro ocular seja negligenciado 49,50 . Estudos recentes sugerem que até 50% da população pode apresentar sintomas sugestivos de alergia ocular, o que se denomina rinoconjuntivite alérgica (RCA) 51 . Dados nacionais apontam ainda que, comparando pacientes asmáticos atópicos e não atópicos, a frequência de sintomas nasais não diferia entre os grupos, mas a presença de sintomas oculares era associada ao fenótipo alérgico 52 .…”

Die saisonale und perenniale allergische Rhinokonjunktivitis

“…Sowohl bei der allergischen Rhinitis als auch bei der allergischen Konjunktivitis handelt es sich um weit verbreitete Krankheitsbilder, deren Prävalenz in Übereinstimmung mit der steigenden Anzahl an allergischen Erkrankungen insgesamt in den letzten Jahren zuzunehmen scheint [2,3,7,8]. Oft fallen okuläre und nasale Symptome zusammen, sodass in der Literatur häufig nur Angaben zur Prävalenz des Komplexes der Rhinokonjunktivitis ohne genaue Abgrenzung zwischen dem Auftreten von Rhinitis und Konjunktivitis zu finden sind [2,9,10]. Die allergische Konjunktivitis wird dabei als Komorbidität der allergischen Rhinitis und des Asthmas angesehen [9].…”

“…Schätzungen der Prävalenz der allergischen Konjunktivitis in den USA belaufen sich auf 15-20% [9]. Eine brasilianische Studie gibt anhand einer Befragung von 3000 Jugendlichen eine Prävalenz der allergischen Konjunktivitis von 20,7 % unter Heranwachsenden an [10]. In anderen Studien werden Prävalenzwerte von 15-20 % bzw.…”
