RESUMEN
PURPOSE: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. METHOD: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. RESULTS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach's α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. CONCLUSIONS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

RESUMEN
Introdução: A conjuntivite alérgica (CA) é uma doença inflamatória da conjuntiva ocular causada principalmente por mecanismo IgE-mediado. É o tipo mais comum de alergia ocular. O presente estudo teve por objetivo identificar fatores associados à CA de diferentes intensidades em pacientes acompanhados em ambulatório pediátrico especializado em doenças alérgicas, visando, assim, facilitar o diagnóstico, a terapêutica e a profilaxia dessa morbidade. Métodos: Este estudo retrospectivo analisou prontuários de pacientes (n = 120) com diagnóstico clínico de CA acompanhados em ambulatório especializado por pelo menos um ano. O diagnóstico de CA foi realizado por oftalmologista, e, segundo os medicamentos utilizados, os pacientes foram classificados em CA grave (corticosteroide oral, imunossupressor tópico ou sistêmico e/ou com lesão corneana) ou não grave. Todos foram submetidos a testes cutâneos de leitura imediata com bateria padronizada de aeroalérgenos. Quinze pacientes foram escolhidos aleatoriamente e submetidos à pesquisa de IgE sérica específica (ImmunoCap-ISAC; Thermo Scientific). Resultados: Formas graves de CA ocorreram em 36/120 pacientes, com predomínio de sexo masculino (86,1%), presença de história familiar de CA e uso de lubrificantes e de imunossupressores tópicos. Não houve diferenças quanto à sensibilização a aeroalérgenos, mas entre as formas graves predominou a polissensibilização. Houve predomínio de sensibilização aos ácaros da poeira domiciliar. Conclusão: Nosso estudo-piloto mostrou que formas graves de CA foram associadas ao sexo masculino, ter história familiar de conjuntivite alérgica, e ser sensibilizado a ácaros da poeira domiciliar. Estudos adicionais são necessários para melhor caracterizar os possíveis fatores de risco associados à maior gravidade da CA.
Introduction: Allergic conjunctivitis (AC) is an inflammatory disease of the ocular conjunctiva mainly caused by IgE-mediated mechanism. It is the most common type of ocular allergy. The present study aimed to identify factors associated with AC of different degrees of severity in patients followed in a pediatric outpatient clinic specializing in allergic diseases, in order to facilitate the diagnosis, therapy and prophylaxis of this morbidity. Methods: This retrospective study assessed medical records of patients (n = 120) with clinical diagnosis of AC followed at a specialized outpatient clinic for at least one year. The diagnosis of AC was performed by an ophthalmologist and, according to the medications used, the patients were classified as having severe AC (oral corticosteroid, topical or systemic immunosuppressive drug and/or corneal injury) or non-severe AC. All patients underwent skin prick tests with a standardized battery of aeroallergens. Fifteen patients were randomly selected to undergo serum specific IgE screening (ImmunoCap-ISAC; Thermo Scientific). Results: Severe forms of AC occurred in 36/120 patients with predominance of male sex (86.1%), presence of family history of AC, and use of lubricants and topical immunosuppressive drugs. There were no differences in sensitization to aeroallergens, but polysensitization prevailed among the severe forms. There was a predominance of sensitization to house dust mites. Conclusion: Our pilot study showed that severe forms of AC were associated with being male, having a family history of allergic conjunctivitis and being sensitized to house dust mites. Additional studies are needed to better characterize possible risk factors associated with increased AC severity.
