Inflammatory markers in palatine tonsils of children with obstructive sleep apnea syndrome / Marcadores inflamatórios em tonsilas palatinas de crianças com síndrome da apneia obstrutiva do sono

Abstract Introduction Obstrutive sleep apnea syndrome is characterized by repeated episodes of upper airway obstruction, associated with intermittent hypoxia and hypercapnia, and the main risk factor in childhood is adenotonsillar hypertrophy. The lymphocytes in these structures are responsible for local and systemic immune responses. Objective Verify the levels of the inflammatory markers, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-15, TNF-α, CRP and α1-GP, in the tonsils of children with and without obstructive sleep apnea syndrome. Methods This cross-sectional prospective study included 34 children with complains of snoring, difficulty breathing during sleep or recurrent tonsillitis. Patients underwent to a complete otorhinolaryngological examination, nasal endoscopy and polysomnography and were divided into two groups with 17 children each: obstructive sleep apnea syndrome group and control group. All underwent an adenotonsillectomy. Cytokines were measured in the collected tonsils (ELISA and Multiplex methods). Results Statistically significant increasing were observed between IL-8 and IL-10 cytokines of patients with obstructive sleep apnea when compared to the control group; also between c-reactive protein and α1-GP of the tonsils cortical region in children with obstructive sleep apnea syndrome when compared with the medullary region. There were no statistically significant differences for the remaining inflammatory mediators. Conclusion After the analysis of the levels of pro and anti-inflammatory markers (IL-1β, IL-4, IL-6, IL-8, IL-10, Il-15, TNF-α, CRP, α1-GP) in the tonsils, we observed higher levels of markers IL-8 and IL-10 in pediatric patients with obstructive sleep apnea syndrome.

Resumo Introdução A síndrome da apneia obstrutiva do sono é caracterizada por episódios repetidos de obstrução das vias aéreas superiores, associados a hipóxia intermitente e hipercapnia, e o principal fator de risco na infância é a hipertrofia adenotonsilar. Os linfócitos nessas estruturas são responsáveis por respostas imunes locais e sistêmicas. Objetivo Dosar os marcadores inflamatórios, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-15, TNF-α, PCR e α1-GP, nas tonsilas de crianças com e sem síndrome da apneia obstrutiva do sono. Método Estudamos prospectivamente 34 crianças que se queixavam de ronco, dificuldade para respirar durante o sono ou tonsilites recorrentes. Os pacientes foram submetidos a exame otorrinolaringológico completo, endoscopia nasal e polissonografia e foram divididos em dois grupos com 17 crianças cada: síndrome de apneia obstrutiva do sono e controle. Todos foram submetidos à adenotonsilectomia. As citocinas foram medidas nas tonsilas coletadas (métodos ELISA e Multiplex). Resultados Com diferenças estatisticamente significantes, observou-se aumento das citocinas IL-8 e IL-10 em pacientes com apneia obstrutiva do sono em comparação ao grupo controle, assim como aumento dos níveis de proteína C reativa e de α1-GP na região cortical das tonsilas de crianças portadoras de síndrome da apneia obstrutiva do sono em comparação com a região medular. Não houve diferenças estatisticamente significantes para o restante dos mediadores inflamatórios. Conclusão Após a análise dos níveis de marcadores pró e anti-inflamatórios (IL-1β, IL-4, IL-6, IL-8, IL-10, Il-15, TNF-α, PCR, α1-GP) nas tonsilas, observamos níveis mais altos de marcadores IL-8 e IL-10 em pacientes pediátricos com síndrome da apneia obstrutiva do sono.

Topical therapy with high-volume budesonide nasal irrigations in difficult-to-treat chronic rhinosinusitis / Terapia tópica de irrigação nasal de alto volume com solução de budesonida em rinossinusite crônica de difícil tratamento

ABSTRACT INTRODUCTION: Chronic rhinosinusitis (CRS) is termed difficult-to-treat when patients do not reach acceptable level of control despite adequate surgery, intranasal corticosteroid treatment and up to 2 short courses of systemic antibiotics or corticosteroids in the preceding year. Recently, high-volume corticosteroid nasal irrigations have been recommended for CRS treatment. OBJECTIVE: To assess high-volume budesonide nasal irrigations for difficult-to-treat CRS. METHODS: Prospective uncontrolled intervention trial. Participants were assessed before- and 3 months after nasal irrigation with 1 mg of budesonide in 500 mL of saline solution daily for 2 days. Subjective (satisfactory clinical improvement) and objective (SNOT-22 questionnaire and Lund-Kennedy endoscopic scores) assessments were performed. RESULTS: Sixteen patients were included, and 13 (81.3%) described satisfactory clinical improvement. SNOT-22 mean scores (50.2-29.6; p = 0.006) and Lund-Kennedy mean scores (8.8-5.1; p = 0.01) improved significantly. Individually, 75% of patients improved SNOT-22 scores, and 75% improved Lund-Kennedy scores after high volume budesonide nasal irrigations. CONCLUSION: High-volume corticosteroid nasal irrigations are a good option in difficult-to-treat CRS control of disease, reaching 81.3% success control and significant improvement of SNOT-22 and Lund-Kennedy scores.

RESUMO INTRODUÇÃO: A rinossinusite crônica (RSC) de difícil tratamento é aquela inadequadamente controlada com cirurgia, corticosteroides tópicos em spray e até dois ciclos de medicação sistêmica em um ano. Atualmente, tem sido preconizado o uso de irrigações nasais de corticosteroides em alto volume para seu tratamento. OBJETIVO: Avaliar o uso da terapia tópica de irrigações nasais com budesonida em alto volume nos pacientes com RSC de difícil tratamento. MÉTODO: Estudo prospectivo de intervenção não controlado em RSC de difícil tratamento com 3 meses de terapia tópica de irrigação (1 mg de budesonida diluído em 500 mL de soro fisiológico para ser utilizado em dois dias). Realizada avaliação subjetiva (melhora clínica satisfatória) e objetiva (questionário SNOT-22 e classificação endoscópica de Lund-Kennedy). RESULTADOS: Foram incluídos 16 pacientes, sendo que 13 (81,3%) consideraram sua melhora clínica satisfatória. Houve melhora significante das médias de SNOT-22 (50,2 a 29,6; p = 0,006) e de Lund-Kennedy (8,8 a 5,1; p = 0,01). Individualmente, 75% dos pacientes apresentaram melhora do SNOT-22 e 75%, do Lund-Kennedy. CONCLUSÃO: A terapia tópica de irrigação de alto volume de corticosteroide é uma boa opção no controle clínico dos pacientes com rinossinusite crônica de difícil tratamento, com controle adequado de 81,3% destes pacientes e melhora significante do SNOT-22 e do Lund-Kennedy.

Long-term outcomes of endoscopic sinus surgery for chronic rhinosinusitis with and without nasal polyps.

UNLABELLED: Chronic rhinosinusitis (CRS) significantly affects patient quality of life. Medical and surgical treatments aim to clinically manage the condition. OBJECTIVE: To assess the long-term quality of life and clinical management of CRS in patients submitted to endoscopic sinus surgery. METHOD: This prospective cross-sectional cohort study enrolled 38 patients and looked into the follow-up data of subjects diagnosed with CRS before surgery, three months after surgery, and at least two years after surgery. The Sinonasal Outcome Test 22 (SNOT-22) was used to assess response to treatment and long-term clinical management of the disease. RESULTS: Significant improvements in the SNOT-22 scores were seen between the preoperative (61.3) and postoperative assessments with three (16.9) and 24 (32.3) months. No statistically significant differences were seen when patients with polyps were compared to polyp-free subjects. Few patients were controlled in both groups, and 7.89% of the subjects had revision surgery during the study. CONCLUSION: Endoscopic sinus surgery significantly improved the quality of life of patients with chronic rhinosinusitis. Clinical control of the condition was acceptable, with few patients requiring re-operation within two years of the first surgery.

Resultados em longo prazo da cirurgia endoscópica nasossinusal no tratamento da rinossinusite crônica com e sem pólipos nasais / Long-term outcomes of endoscopic sinus surgery for chronic rhinosinusitis with and without nasal polyps

Rinossinusite crônica (RSC) afeta significativamente a qualidade de vida e o tratamento clínico e cirúrgico visa apenas seu controle clínico. OBJETIVO: Avaliar a qualidade de vida e o controle clínico da RSC em longo prazo em pacientes submetidos à cirurgia endoscópica nasossinusal. MÉTODO: Estudo observacional longitudinal prospectivo que seguiu pacientes com diagnóstico clínico de RSC no pré-operatório, pós-operatório de 3 meses e depois por no mínimo 2 anos após cirurgia nasossinusal endoscópica com a utilização do questionário Sinonasal Outcome Test 22 (SNOT-22) como principal medida de resposta ao tratamento, além da avaliação do controle clínico a longo prazo. RESULTADOS: Trinta e oito pacientes foram avaliados em todos os intervalos. Houve uma grande melhora dos valores do SNOT-22 entre o pré-operatório (61,3) e o pós-operatório de 3 (16,9) e 24 meses (32,3). Não houve diferença estatisticamente significante entre os pacientes com e sem pólipos nasais. Nota-se pouca proporção de pacientes controlados em ambos os grupos, e 7,89% foram submetidos à cirurgia revisional no período estudado. CONCLUSÃO: A cirurgia endoscópica nasossinusal promoveu importante melhora da qualidade de vida nos pacientes com rinossinusite crônica, atingindo controle clínico aceitável com baixa necessidade de reintervenção cirúrgica, mesmo após dois anos de seguimento pós-operatório.

Mastoiditis and facial paralysis as initial manifestations of Wegener's Granulomatosis.

UNLABELLED: Wegener's Granulomatosis (WG) is characterized by necrotizing granulomas and vasculitis. If left untreated, the prognosis is poor--a 90% mortality rate within 2 years. Several authors have described the otologic manifestations of WG; these authors, however, have not mentioned the stage of the disease in which these findings present--whether as initial manifestations or subsequent to other findings. AIM: To describe three confirmed cases of WG with mastoiditis as the first manifestation, progressing to peripheral facial paralysis (PFP). MATERIAL AND METHOD: A clinical series study. Patients diagnosed with WG that initially presented with otologic findings are described. RESULTS: The three cases presented with unilateral otalgia, otorrhea, and hearing loss associated with ipsilateral PFP. None recovered in spite of the treatment; an investigation of associated diseases was therefore undertaken. Positive ANCA-C titers where detected in all patients, confirming the diagnosis of WG. Clinical improvement was seen after treatment of WG; the PFP regressed and hearing thresholds improved partially. CONCLUSION: Complications of otitis media (mastoiditis and PFP) that do not respond to the usual treatment require an investigation of associated diseases; WG should be included for an early diagnosis to change the prognosis in these patients.

Mastoidite e paralisia facial como manifestações iniciais de Granulomatose de Wegener / Mastoiditis and facial paralysis as initial manifestations of Wegener's Granulomatosis

A Granulomatose de Wegener (GW) é caracterizada por granulomas necrotizantes e vasculite. Sem tratamento a doença tem prognóstico pobre com índice de mortalidade de 90% em 2 anos. Diversos autores citam as manifestações otológicas no curso da GW, entretanto não é especificado em que momento da doença elas apareceram, isto é, se como manifestação inicial ou subsequente a outros achados. Objetivo: Descrever três casos confirmados de GW que apresentaram inicialmente mastoidite e evoluíram com paralisia facial periférica (PFP). Material e Método: Estudo de série de casos. Pacientes diagnosticados com GW que apresentaram inicialmente manifestações otológicas são descritos. Resultados: Os três casos descritos abriram o quadro com otalgia, otorreia e hipoacusia unilateral, associada a paralisia facial periférica ipsilateral. Tiveram resposta inadequada aos tratamentos instituídos o que motivou uma investigação de outras doenças associadas. Nessas circunstâncias, detectaram-se títulos positivos de ANCA-C em todos pacientes, confirmando-se o diagnóstico de GW, após período variável de investigação. Institui-se o tratamento para GW observando-se melhora do quadro clínico, regressão da PFP e melhora parcial dos limiares auditivos. Conclusão: Complicações de otites médias agudas (mastoidite e PFP) refratárias as terapêuticas habituais impõem a investigação de doenças associadas e a GW deverá ser pesquisada para que se possa fazer o diagnóstico o mais precocemente possível, alterando desta forma o prognóstico destes pacientes.

Esta atualização pretende abordar de forma prática, como diagnosticar, classificar e tratar a rinite alérgica.

Translation, cross-cultural adaptation and validation of SinoNasal Outcome Test (SNOT): 22 to Brazilian Portuguese.

UNLABELLED: Quality of life questionnaires have been increasingly used in clinical trials to help establish the impact of medical intervention or to assess the outcome of health care services. Among disease-specific outcome measures, SNOT-22 was considered the most suitable tool for assessing chronic rhinosinusitis and patients with nasal polyps. AIMS: To perform translation, cross-cultural adaptation and validation of the SNOT-22 to Brazilian Portuguese. METHODS: Prospective study involving eighty-nine patients with chronic rhinosinusitis or nasal polyps submitted to functional endoscopic sinus surgery, who answered the questionnaire before and after surgery. Furthermore, 113 volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reliability, measure validity, responsiveness and clinical interpretability were assessed. RESULTS: Mean preoperative, postoperative and no sinonasal disease scores were 62.39, 23.09 and 11.42, respectively (p<0.0001); showing validity and responsiveness. Internal consistency was high (Cronbach's alpha = 0.9276). Reliability was sufficiently good, considering inter-interviewers (r=0.81) and intra-interviewers within a 10 to 14 day-interval (r=0.72). Surgery effect size was 1.55. Minimally important difference was 14 points; and scores up to 10 points were considered normal. CONCLUSION: The Brazilian Portuguese SNOT-22 version is a valid instrument to assess patients with chronic rhinosinusitis and nasal polyps.
