ABSTRACT
BACKGROUND: Local allergic rhinitis (LAR) is a well-defined and reported phenotype in adults, but data is scarce for children and adolescents, and it is probably an undiagnosed and highly underestimated condition in childhood. OBJECTIVES: The objectives of this systematic review were to identify original observational studies published on LAR in children and adolescents and to describe the prevalence and characteristics of this phenotype in the pediatric age group. METHODS: A systematic search was performed in PubMed and EMBASE databases. The search was limited to publications on humans, written in English, published between January 1, 2000 and September 20, 2021. Participants had to be under 18 years old and with a diagnosis of LAR confirmed by nasal allergen provocation test (NAPT). RESULTS: Ten articles were identified. Despite the wide variability of protocols, prevalence rates ranged from 3.7 to 83.3% among children previously diagnosed as having nonallergic rhinitis, being markedly lower in Eastern countries (3.7-16.6%) when compared to Western countries (22.3-83.3%). To date, no relevant clinical characteristics capable of differentiating LAR patients from other childhood rhinitis phenotypes have been identified. CONCLUSIONS: LAR is an allergic rhinitis phenotype also found in children. Population and regional differences and differences in NAPT protocols may explain the heterogeneity in LAR prevalence rates observed in different parts of the world. In addition to clarifying this large discrepancy, longitudinal studies are also needed to assess the clinical characteristics of the LAR phenotype in the pediatric age group, and its stability into adulthood must be confirmed.

A alergia ocular, também conhecida como conjuntivite alérgica (CA), é uma reação de hipersensibilidade mediada por imunoglobulina E (IgE) do olho desencadeada por aeroalérgenos, principalmente ácaros da poeira doméstica e pólen de gramíneas. Os sintomas geralmente consistem em prurido ocular ou periocular, lacrimejamento e olhos vermelhos que podem estar presentes durante todo o ano ou sazonalmente. A alergia ocular tem frequência elevada, é subdiagnosticada e pode ser debilitante para o paciente. É potencialmente danosa para a visão, nos casos em que ocasiona cicatrização corneana grave, e na maioria dos pacientes associa-se a outros quadros alérgicos, principalmente rinite, asma e dermatite atópica. É classificada em conjuntivite alérgica perene, conjuntivite alérgica sazonal, ceratoconjuntivite atópica e ceratoconjuntivite vernal. O diagnóstico procura evidenciar o agente etiológico e a confirmação se dá pela realização do teste de provocação conjuntival. O tratamento baseia-se em evitar o contato com os desencadeantes, lubrificação, anti-histamínicos tópicos, estabilizadores de mastócitos, imunossupressores e imunoterapia específica com o objetivo de obter o controle e prevenir as complicações da doença.
Ocular allergy, also known as allergic conjunctivitis, is an immunoglobulin E-mediated hypersensitivity reaction of the eye triggered by airborne allergens, primarily house dust mites and grass pollen. Symptoms usually consist of ocular or periocular itching, watery eyes, and red eyes that may be present year-round or seasonally. Ocular allergy has a high frequency, is underdiagnosed, and can be debilitating for the patient. It is potentially harmful to vision in cases of severe corneal scarring, and in most patients, it is associated with other allergic conditions, especially rhinitis, asthma, and atopic dermatitis. It is classified as perennial allergic conjunctivitis, seasonal allergic conjunctivitis, atopic keratoconjunctivitis, and vernal keratoconjunctivitis. Diagnosis seeks to identify the etiologic agent, and confirmation is given by conjunctival provocation testing. Treatment is based on avoiding contact with triggers, lubrication, topical antihistamines, mast cell stabilizers, immunosuppressants, and specific immunotherapy with the aim of achieving control and preventing disease complications.

A rinite no pré-escolar configura um grande desafio diagnóstico e terapêutico, tanto para pediatras, como para especialistas. Os poucos dados existentes nesta faixa etária, além da sobreposição dos sintomas também comuns às doenças respiratórias virais, tornam o diagnóstico de rinite extremamente raro e/ou frequentemente ignorado. A melhor compreensão e identificação da rinite nos pré-escolares pode ajudar a melhorar a qualidade de vida destes pacientes, através da instituição do diagnóstico e tratamento corretos. Além disso, o diagnóstico mais precoce, possivelmente possibilitará caracterizar melhor a história natural da rinite, comorbidades, fatores de risco e o acompanhamento do desenvolvimento dos diferentes fenótipos da rinite ao longo da vida.
Rhinitis in preschool children is a major diagnostic and therapeutic challenge for both pediatricians and specialists. The diagnosis of rhinitis is extremely rare and/or often ignored in this specific age group, due to the few data available and the overlapping of symptoms common to viral respiratory diseases. A better understanding and identification of rhinitis in preschool children could improve the quality of life of these patients by making diagnosis more accurate and delivering appropriate treatment. In addition, an earlier diagnosis may help better understand the natural history of rhinitis, comorbidities, risk factors and follow-up of different phenotypes throughout life.

BACKGROUND: Currently, the diagnosis of allergic rhinitis (AR) is arrived at predominantly by a clinical history and by systemic sensitization tests, but specific nasal provocation tests (NPT) may establish a better direct correlation between etiologic surveyed allergens and nasal symptoms. OBJECTIVES: To standardize the specific NPT with one of the most important house-dust mites, Dermatophagoides pteronyssinus, monitored by acoustic rhinometry, in children and adolescents, and propose a simplified specific NPT to improve its clinical applicability as a diagnostic tool. METHODS: Sixteen controls (group 1) and 17 patients with an AR diagnosis sensitized to D. pteronyssinus (group 2) underwent a specific NPT with D. pteronyssinus. The acoustic rhinometry was performed after instillation of 0.15 mL of increasing concentrations of D. pteronyssinus (5000 BU/mL). The test was finalized after (1) instillation of the final concentration of D. pteronyssinus, or (2) after a 20% or more reduction in the volume of the first 5 cm of the nasal cavity (V5), or (3) a score of >3 in the symptoms questionnaire (a score from 0 to 7). A simplified specific NPT with two concentrations was proposed and implemented in a group of 10 patients with AR (group 3). RESULTS: At the end of the specific NPT, the median (range) variation in V5 was -5.7% (-9 to 4%) in the control group and -22.8% (-24 to -20%) in group 2. None of the patients in the control group and 88% of group 2 (15/17) showed positive specific NPT results. The simplified specific NPT triggered a positive response in 80% of patients in group 3, with median (range) V5 variation of -30.4% (-36 to -20%). CONCLUSION: This protocol has been proven safe and useful to differentiate between children and adolescents with AR and controls. Concentrations of 1:1000 and 1:100 D. pteronyssinus were the best for use in simplified specific NPT, which made it simpler and faster, and expanded its clinical applicability.

Abstract Introduction: The Rhinitis Control Assessment Test (RCAT) is a simple self-administered questionnaire developed to assess control of rhinitis. Objectives: Translate into Brazilian Portuguese and validate the RCAT. Methods: The RCAT was translated into Portuguese by two translators and subsequently back-translated into English. It was then applied to 141 adolescents with allergic rhinitis. Results: The internal consistency of the RCAT was 0.73. The questionnaire scores showed significant correlation with total nasal and extra-nasal symptom scores and nasal peak inspiratory flow (r: −0.73, −0.58 and 0.52, respectively; p < 0.001) and were significantly different when divided by physician global assessment and total nasal symptom score severity. Cutoff points between 22 and 24 had the higher areas under the ROC curve to identify patients with rhinitis control. Total nasal and extra-nasal symptom scores were significantly different when a cutoff point of 22 was used (median: 4.0 vs. 8.0 and 2.0 vs. 5.0; p < 0.001). Conclusions: The Brazilian Portuguese version of the RCAT was shown to be a valid and discriminant tool to identify patients with controlled and uncontrolled allergic rhinitis.
Resumo Introdução: O Rhinitis Control Assessment Test (RCAT) é um questionário simples e autoaplicável desenvolvido para avaliar o controle da rinite. Objetivos: Traduzir para o Português validar o RCAT. Método: A tradução do RCAT foi feita por dois tradutores com posterior versão para a Língua Inglesa. O RCAT foi então aplicado de forma transversal a 141 adolescentes com rinite alérgica. Resultados: A consistência interna do RCAT foi 0,73. As notas totais do questionário se correlacionaram significantemente com os escores de sintomas nasais e extra-nasais e pico de fluxo inspiratório nasal (r: -0,73, -0,58 e 0,52, respectivamente; p < 0,001) e foram significantemente diferentes quando separadas pela opinião médica sobre o controle da rinite e pela gravidade dos sintomas nasais. Os pontos de corte entre 22 e 24 foram os com maiores áreas sob a curva ROC para definição do controle da rinite. Os escores de sintomas nasais e extra-nasais foram significantemente diferentes quando os pacientes foram separados pelo ponto de corte de 22 (medianas de 4,0 vs. 8,0 e 2,0 vs. 5,0; p < 0,001). Conclusões: A versão em Português do RCAT se mostrou uma ferramenta válida e com bom poder discriminativo para separar pacientes com rinite alérgica controlada e não controlada.
