La rinitis alérgica (RA) es una de las enfermedades crónicas más frecuentes de la infancia. Sin embargo, permanece subdiagnosticada y subtratada. Su prevalencia ha aumentado en los últimos años y varía del 2 % al 25 %. Los síntomas de la RA incluyen estornudos, prurito, rinorrea y congestión nasal. Un correcto diagnóstico y tratamiento de la RA y sus comorbilidades, tales como rinosinusitis con o sin poliposis nasal, conjuntivitis, otitis media, asma bronquial e infecciones del tracto respiratorio, son importantes para reducir el impacto negativo en la afectación de la calidad de vida del paciente y sus familiares, y los gastos sanitarios que ocasiona. La inmunoterapia alérgeno específica, en pacientes correctamente seleccionados, previene nuevas sensibilizaciones y reduce la hiperreactividad bronquial asociada a la RA. Considerando todos estos factores, el Comité Nacional de Alergia de la Sociedad Argentina de Pediatría propone recomendaciones basadas en la evidencia actual.

Allergic rhinitis (AR) is one of the most common chronic diseases in children. However, it remains underdiagnosed and undertreated. Its prevalence has increased in recent years and varies from 2 to 25 %. Symptoms include sneezing, itching, runny nose, and nasal congestion. A correct diagnosis and treatment of AR and its comorbidities such as rhinosinusitis with or without nasal polyposis, conjunctivitis, otitis media, bronchial asthma and respiratory tract infections, are important to reduce the negative impact on the quality of life of the patient and their relatives, and in medical costs. Specific allergen immunotherapy, in correctly selected patients, prevents new sensitizations and reduces bronchial hyperreactivity associated with AR. Taking into account all these reasons, the National Allergy Committee of the Sociedad Argentina de Pediatría proposes current evidence based recommendations

Objective: To investigate the effects and clinical significance of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome activated by interleukin (IL)-17A in chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: Patients underwent nasal endoscopic surgery in the Third Affiliated Hospital of Sun Yat-sen University from January 2020 to December 2021 were collected, including 28 CRSwNP (including 19 males and 9 females, aged 19 to 67 years), 22 chronic rhinosinusitis without nasal polyps (CRSsNP) and 22 controls. qRT-PCR was used to detect the expressions of IL-17A, NLRP3, IL-1β and IL-18 in the three groups, and their correlations were analyzed. The positions of IL-17A, NLRP3 and IL-18 in nasal polys were analyzed by immunofluorescence. Western Blotting and ELISA were employed to detect the expression of NLRP3, IL-1β and IL-18 in the human nasal epithelial cells after using IL-17A stimulation or IL-17A receptor inhibitor. Immunofluorescence was used to observe the NLRP3, IL-1β, and IL-18 protein expression after IL-17A stimulating human nasal epithelial cells, and after the use of IL-17A receptor inhibitor and NLRP3 inhibitor MCC950. The correlations between NLRP3, IL-1β, IL-18 and CT scores, nasal endoscopic scores, visual analogue scale (VAS) scores, and sino-nasal outcome test (SNOT) 22 scores of CRSwNP patients were analyzed. SPSS 20.0 software was used for statistical analysis. Results: The expressions of IL-17A, NLRP3, IL-1β and IL-18 in the tissues of CRSwNP patients were significantly higher than those in CRSsNP group(P=0.018,P<0.001,P=0.005, P=0.016) and the control group(all P<0.001). IL-17A was positively correlated with the expression of NLRP3, IL-1β, and IL-18(r ralue was 0.643,0.650,0.629,respectively, all P<0.05). IL-17A, NLRP3, and IL-18 were co-localized in the epithelial propria of polyp tissue. IL-17A stimulated the expressions of NLRP3, IL-1β, and IL-18 in human nasal epithelial cells. After the use of IL-17A receptor inhibitor, the expressions of NLRP3, IL-1β, and IL-18 were significantly down-regulated. After the use of NLRP3 inhibitor MCC950, IL-17A was significantly down-regulated to promote the expression of NLRP3, IL-1β, and IL-18. The expressions of NLRP3, IL-1β and IL-18 were positively correlated with CT, nasal endoscopy, VAS, and SNOT22 scores in patients with CRSwNP. Conclusions: IL-17A promotes the release of IL-1β and IL-18 by activating the NLRP3 inflammasome and aggravates the severity of the disease in CRSwNP.

Objective: To investigate the clinical efficacy and safety of anti-IgE monoclonal antibody (omazumab) in the treatment of allergic united airway disease (UAD) in the real-wold. Methods: Retrospective cohort study summarizes the case data of patients with allergic united airway disease who were treated with anti IgE monoclonal antibody (omalizumab) for more than 16 weeks from March 1, 2018 to June 30, 2022 in the Peking University First Hospital.The allergic UAD is defined as allergic asthma combined with allergic rhinitis (AA+AR) or allergic asthma combined with chronic sinusitis with nasal polyps (AA+CRSwNP) or allergic asthma combined with allergic rhinitis and nasal polyps (AA+AR+CRSwNP). The control of asthma was evaluated by asthma control test (ACT), lung function test and fractional exhaled nitric oxide (FeNO). The AR was assessed by total nasal symptom score (TNSS). The CRSwNP was evaluated by nasal visual analogue scale (n-VAS), sino-nasal outcome test-22 (SNOT-22), nasal polyps score (TPS) and Lund-Mackay sinus CT grading system. The global evaluation of omalizumab for the treatment of allergic UADwas performed by Global Evaluation of Treatment Effectiveness(GETE).The drug-related side effects were also recorded. Matched t test and Wilcoxon signed-rank test were used to compare the score changes of IgE monoclonal antibody (omazumab) before and after treatment, and multivariate logistic regression analysis was used to determine the influencing factors of IgE monoclonal antibody (omazumab) response. Results: A total of 117 patients with UAD were enrolled, ranging in age from 19 to 77 years; The median age of patients was 48.7 years; Among them, 60 were male, ranging from 19 to 77 years old, with a median age of 49.9 years; There were 57 females, ranging from 19 to 68 years old, with a median age of 47.2 years. There were 32 cases in AA+AR subgroup, 59 cases in AA+CRSwNP subgroup, and 26 cases in AA+AR+CRSwNP subgroup. The total serum IgE level was 190.5 (103.8,391.3) IU/ml. The treatment course of anti IgE monoclonal antibody was 24 (16, 32) weeks. Compared with pre-treatment, omalizumab increased ACT from 20.0 (19.5,22.0) to 24.0 (23.0,25.0) (Z=-8.537, P<0.001), increased pre-bronchodilator FEV1 from 90.2 (74.8,103.0)% predicted value to 95.4 (83.2,106.0)% predicted value (Z=-5.315,P<0.001), increased FEV1/FVC from 80.20 (66.83,88.38)% to 82.72 (71.26,92.25)% (Z=-4.483,P<0.001), decreased FeNO from(49.1±24.8) ppb to (32.8±24.4) ppb (t=5.235, P<0.001), decreased TNSS from (6.5±2.6)to (2.4±1.9) (t=14.171, P<0.001), decreased n-VAS from (6.8±1.2) to (3.4±2.0)(t=14.448, P<0.001), decreased SNOT-22 from (40.0±7.9) to (21.3±10.2)(t=15.360, P<0.001), decreased TPS from (4.1±0.8) to (2.4±1.0)(t=14.718, P<0.001) and decreased Lund-Mackay CT score from (6.0±1.3) to (3.1±1.6)(t=17.012, P<0.001). The global response rate to omalizumab was 67.5%(79/117). The response rate in AA+AR (90.6%,29/32) was significantly higher than that in AA+CRSwNP (61.0%,36/59) and AA+AR+CRSwNP (53.8%,14/26) subgroups (χ2=11.144,P=0.004). Only 4 patients (3.4%,4/117) had mild side effects. Conclusion: The real-world study showed favorable effectiveness and safety of anti-IgE monoclonal antibody for treatment of allergic UAD. To provide basis for preventing the progress and precise treatment of allergic UAD.

Objective:To investigate the efficacy of functional endoscopic sinus surgery(FESS) in the treatment of olfactory dysfunction in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) , at the same time, it provides an evidence for the prognosis evaluation of olfaction and the clinical application of oERPs to evaluate the plasticity of olfaction cortex. Methods:From October 2021 to October 2022, 45 patients with CRSwNP who underwent FESS nine-step standardized treatment in our department were recruited as the research subjects, divided into 22 patients with eosinophilic CRSwNP(ECRS)and 23 patients with non-eosinophilic CRSwNP(nECRS). VAS-olfactory dysfunction (VAS-OD) score, SNOT-22 olfactory score, Sniffin' Sticks test and oERPs collection and processing were performed before the operation. All items were evaluated again 3 months after the operation. Results:VAS-OD and SNOT-22 olfactory score were significantly lower in all CRSwNP patients after the operation than those before the operation[F(1, 43) =357.429, P<0.001; F(1, 43) =185.657, P<0.001], the scores of T, D, I and TDI scores in Sniffin' Sticks test were significantly higher than those before the operation[F(1, 43) =126.302, P<0.001; F(1, 43) =311.301, P<0.001; F(1, 43) =131.401, P<0.001; F(1, 43) =295.885, P<0.001]; The decrease of VAS-OD and SNOT-22 olfactory score in the ECRS group was smaller than that in the nECRS group[F(1, 43) =4.825, P=0.033; F(1, 43) =9.916, P=0.003], T, D and TDI scores were significantly lower in nECRS group than those in nECRS group[F(1, 43) =6.719, P=0.013; F(1, 43) =4.890, P=0.032; F(1, 43) =4.469, P=0.040]; There was a positive correlation between preoperative eosinophil-to-lymphocyte ratio(ELR) and SNOT-22 olfactory score and how much it changes(r=0.455, P=0.002; r=-0.414, P=0.005), a negative correlation between T, TDI score and how much they change respectively(r=-0.431, P=0.003; r=-0.385, P=0.009; r=-0.383, P=0.010; r=-0.316, P=0.035). The latency of P3 was significantly shorter after operation than that before operation in all CRSwNP patients[F(1, 14) =24.840, P<0.001], however, the amplitude has no significant surgical effect. Conclusion:FESS could significantly improve the olfactory function of CRSwNP patients, while changes in plasticity may occur in the olfactory cortex. In addition, the preoperative peripheral blood eosinophil granulocyte level can predict the postoperative olfactory improvement.

The allergen nasal provocation testing(NPT), in which allergens are applied directly to the nasal mucosa under standard and controlled conditions to provoke the main symptoms of allergic rhinitis(AR), reproduces the response of the upper respiratory tract to natural exposure to allergens under controlled conditions and is the only test currently available to confirm nasal reactivity to allergens. It is invaluable in studying the mechanisms of AR and in assessing the response to novel anti-allergic treatments. The test may play an increasingly important role in clinical practice, especially in the identification of local AR, the diagnosis of occupational AR, the clarification of the composition of allergens, the assessment of the efficacy of AR treatment and the selection of candidates undergoing allergen immunotherapy. This article reviewed the application of NPT in the diagnosis of allergic and non-allergic rhinitis, and also introduces the indications, contraindications, advantages and limitations of NPT in evaluating nasal response.

Objective:To investigate the effect of posterior nasal neurectomy(PNN) with pharyngeal neurectomy (PN) on chronic sinusitis with nasal polyps (CRSwNP)complicated with perennial allergic rhinitis (PAR). Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery(FESS)+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups(P>0.05). However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group(P<0.05). Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis (CRS) subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis (eCRS) group (47 cases) and non eosinophilic chronic sinusitis (non-eCRS) group (79 cases). The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio(bEBR), basophils-to-neutrophils ratio(BNR), basophils-to-lymphocytes ratio(BLR), basophils-to-monocytes ratio(BMR) were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio(bEBR) were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio(BNR) were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio(BLR) were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio(BMR) were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group(P<0.01), while there was no statistically significant difference between non-eCRS group and healthy control group(P>0.05). Basophil counts (r=0.185 5, P<0.05), BLR(r=0.226 9, P<0.05), BMR(r=0.228 1, P<0.01) in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils(r=0.479 2, P<0.01), lymphocytes(r=0.259 4, P<0.01), and monocytes(r=0.256 4, P<0.01) in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

Objective:To evaluate the efficacy of glucocorticoid sinus stents implanted 2 weeks after functional endoscopic sinus surgery(FESS) for the treatment of chronic rhinosinusitis with nasal polyps(CRSwNP). Methods:CRSwNP patients with similar bilateral lesions were randomly divided into two groups, with a stent group of 25 patients and a control group of 24 patients. Patients in the stent group had glucocorticoid sinus stents implanted into the bilateral ethmoid sinuses 2 weeks after FESS, while the control group underwent postoperative debridement only. Follow-up assessments occurred at postoperative weeks 2, 4, 8, and 12. Patients were asked to assess their sensation of nasal symptoms using a 10-point visual analog scale. Efficacy was assessed by endoscopic evaluations. Sinus obstruction, crusting/coagulation, polyp formation, middle turbinate position, adhesions, mucosa epithelialization, and postoperative intervention were assessed as efficacy outcomes. GraphPad Prism 9 was applied for statistical analysis. Results:At 4 and 8 weeks postoperatively, the stent group showed significant improvement in VAS scores of nasal congestion and runny nose compared with the control group(P<0.05). No significant difference was observed in the VAS scores of head and facial stuffiness, loss of smell, or nasal dryness/crusting between the two groups(P>0.05). Compared with the control group, the stent group had a lower rate of polypoid formation at 4, 8, and 12 weeks postoperatively. At postoperative week 12, the rate of mucosal epithelialization in the ethmoid cavity was significantly higher in the stent group. During the follow-up, the frequency of postoperative intervention was significantly lower in the stent group than in the control group(P<0.05). Besides, a lower incidence of middle turbinate lateralization was found in the stent group at 8 and 12 weeks postoperatively. At 8 weeks postoperatively, the stent group had a percentage of adhesion lower than that of the control group(all P<0.05). Conclusion:Implantation of glucocorticoid sinus stents after FESS can maintain sinus cavity patency, improve the inflammatory status of the operative cavity, reduce postoperative interventions, and promote benign regression of the operative cavity.

Objective:To investigate the etiological characteristics of nasal bacterial infection in patients with nasal lymphoma. Methods:The results of bacterial culture of nasal secretions from 39 healthy people and 86 patients with nasal lymphoma in the Affiliated Hospital of Qingdao University from January 2019 to June 2022 were retrospectively analyzed, and the differences in nasal bacteria distribution between nasal lymphoma and healthy people were analyzed and compared. Results:Corynebacterium(38.90%) was the most common bacteria in the nasal cavity of healthy people, followed by coagulase-negative Staphylococcus(31.95%), Staphylococcus epidermidis(15.28%) and Staphylococcus aureus(6.95%). The most common bacteria in nasal lymphoma patients was Staphylococcus aureus(30.37%), followed by Corynebacterium(9.63%), Staphylococcus epidermidis(7.41%) and coagulase negative Staphylococcus(6.67%). A total of 81 nasal lymphoma patients were detected with bacteria, positive rate is as high as 94.19%(81/86). Conclusion:Staphylococcus aureus is the main pathogenic bacteria in nasal secretion of patients with nasal lymphoma, which provides guiding significance for the clinical prevention and treatment of nasal lymphoma complicated with infection or not.

Contexto: A suplementação de vitamina é considerada na prevenção de muitas doenças, incluindo a rinite alérgica, cuja prevalência tem aumentado nos últimos anos, impactando a saúde pública. Objetivo: Avaliar a efetividade da suplementação de vitamina D para a prevenção e o tratamento da rinite alérgica. Material e Métodos: Trata-se de sinopse baseada em evidências. Procedeu-se à busca por estudos que associavam a vitamina D à rinite alérgica em três bases eletrônicas de dados: Cochrane - Central de Registros de Ensaios Clínicos - CENTRAL (2022), PubMed (1966-2022) e Portal BVS (1982-2022) e no megabuscador de evidências TRIPDATABASE (2022). Dois pesquisadores independentemente extraíram os dados e avaliaram a qualidade dos estudos para a síntese. O desfecho primário de análise envolveu a redução de crises de rinite. Resultados: Foram encontrados 125 estudos. Cinco estudos (três ensaios clínicos randomizados e dois coortes) foram incluídos. Discussão: A literatura apresenta poucos estudos relacionando vitamina D e rinite alérgica. Os estudos em humanos são ensaios clínicos de baixa amostragem e elevada heterogeneidade, que avaliaram efetividade da suplementação de vitamina D para redução de sintomas da rinite. Os dois estudos coorte encontrados não estabeleceram relação entre a exposição à vitamina D e menor manifestação de doença alérgica. O nível de evidência é muito baixo e não permite, nesse momento, aferir a efetividade da vitamina D para essa finalidade. Conclusões: Não há evidência de efetividade da suplementação de vitamina D para tratamento e prevenção da rinite alérgica, sendo recomendada a realização de novos estudos de boa qualidade metodológica.

El síndrome del edificio enfermo, se refiere a un conjunto de síntomas generales en mucosa (ocular y/o respiratoria) y piel que presentan los ocupantes de edificaciones con calidad ambiental deficientes, exponiendo a sus ocupantes a factores de riesgos físicos, mecánicos, químicos, biológicos y psicosociales, que puede afectar negativamente la salud y productividad de las personas. Con el propósito de determinar la frecuencia de los síntomas de los ocupantes de una industria manufacturera del Perú, se realizó estudio transversal aplicándose a 237 trabajadores, estratificados por áreas laborales, el cuestionario sugerido por el Instituto Nacional de Higiene y Seguridad en el Trabajo, además de evaluar la condición ambiental mediante la determinación de bioaerosoles cultivables y contables. Los resultados mostraron prevalencia superior al 20% en síntomas como: sequedad en ojos y garganta, picor en garganta congestión nasal, dolor de cabeza y debilidad general. Se tomaron, cuantificaron y caracterizaron 164 muestras de bioaerosoles, los microrganismos encontrados con mayor porcentaje fueron, Aspergillus sp. 54,68% (68) en el área administrativa, mientras que en las áreas de producción y almacén predomino Penicillium sp. con 87,10% (108) y 62,21% (77) respectivamente. Otros géneros encontrados en mayor porcentajes, en las tres áreas fueron: Trichoderma, Acremonium, Monilia, Cladosporium, entre otros. Los hallazgos se correlacionan con lo reportado en diversas investigaciones, la presencia de mencionados hongos, sugiere que existe una inadecuada calidad ambiental y aunada a la prevalencia obtenida en cuanto a sintomatología, se puede clasificar la edificación objeto de estudio con el Síndrome del edificio enfermo(AU)

Sick building syndrome refers to a set of general mucosal (ocular and/or respiratory) and skin symptoms presented by occupants of buildings with poor environmental quality, exposing their occupants to physical, mechanical, chemical, biological and psychosocial, which can negatively affect the health and productivity of people. In order to determine the frequency of the symptoms of the occupants of a manufacturing industry in Peru, a cross-sectional study was carried out, applying to 237 workers, stratified by work areas, the questionnaire suggested by the National Institute of Hygiene and Safety at Work, in addition to to evaluate the environmental condition by determining cultivable and countable bioaerosols. The results showed a prevalence greater than 20% in symptoms such as: dry eyes and throat, itchy throat, nasal congestion, headache and general weakness. 164 samples of bioaerosols were taken, quantified and characterized, the microorganisms found with the highest percentage were Aspergillus sp. 54.68% (68) in the administrative area, while in the production and storage areas, Penicillium sp. with 87.10% (108) and 62.21% (77) respectively. Other genera found in higher percentages in the three areas were: Trichoderma, Acremonium, Monilia, Cladosporium, among others. The findings correlate with what has been reported in various investigations, the presence of these fungi suggests that there is an inadequate environmental quality and, together with the prevalence obtained in terms of symptoms, the building under study can be classified with the Sick Building Syndrome(AU)

Abstract Introduction: Chronic rhinosinusitis is an inflammatory condition of the nasal cavity and the paranasal sinuses that requires multifactorial treatment. Xylitol can be employed with nasal irrigation and can provide better control of the disease. Objective: To evaluate the association between the effects of nasal lavage with saline solution compared to nasal lavage with a xylitol solution. Methods: Fifty-two patients, divided into two groups (n = 26 in the "Xylitol" group and n = 26 in the "Saline solution" group) answered questionnaires validated in Portuguese (NOSE and SNOT-22) about their nasal symptoms and general symptoms, before and after endonasal endoscopic surgery and after a period of 30 days of nasal irrigation. Results: The "Xylitol" group showed significant improvement in pain relief and nasal symptom reduction after surgery and nasal irrigation with xylitol solution (p < 0.001). The "Saline solution" group also showed symptom improvement, but on a smaller scale. Conclusion: This study suggests that the xylitol solution can be useful in the postoperative period after endonasal endoscopic surgery, because it leads to a greater reduction in nasal symptoms.

Resumo Introdução: Rinossinusite crônica é um quadro de inflamação da cavidade nasal e dos seios paranasais que necessita de tratamento multifatorial. O xilitol pode ser associado às irrigações nasais e pode prover melhor controle da doença. Objetivo: Avaliar a relação entre os efeitos da lavagem nasal com solução fisiológica em comparação à lavagem nasal com solução de xilitol. Método: Divididos em dois grupos (n = 26 no grupo Xilitol e n = 26 no grupo Soro), 52 pacientes responderam à questionários validados em língua portuguesa (NOSE e SNOT-22) sobre seus sintomas nasais e sintomas gerais, antes e depois de cirurgia endoscópica endonasal e após um período de 30 dias de irrigação nasal. Resultados: O grupo Xilitol apresentou melhoria significativa dos sintomas de dor e sintomas nasais após a cirurgia e a irrigação nasal com solução de xilitol (p < 0,001). O grupo Soro também apresentou melhoria dos sintomas, porém em menor escala. Conclusão: Este estudo sugere que a solução de xilitol pode ser usada no período pós-operatório de cirurgia endoscópica endonasal por levar a uma maior redução nos sintomas nasais.

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.

Introdução: a rinite é um distúrbio respiratório crônico comum, de alta prevalência no Brasil e no mundo, que representa um fardo considerável para os portadores. Está associada a sintomas incômodos, que reduzem a qualidade de vida e do sono, acarretando em prejuízos sociais, emocionais e funcionais. Objetivo: avaliar a qualidade de vida e do sono conforme o grau de incômodo dos sintomas dos pacientes com rinite, acompanhados no Sistema Único de Saúde da região Oeste da Bahia. Metodologia: um estudo de corte transversal que avaliou 169 pacientes entre 12 e 90 anos diagnosticados clinicamente com rinite, atendidos em ambulatório de Otorrinolaringologia no município de Barreiras (Bahia), entre novembro de 2018 a setembro de 2019, através do Questionário Modificado de Qualidade de Vida em Rinoconjuntivite, Escala de Sonolência de Epworth e Índice de Qualidade do Sono de Pittsburgh. Resultados: a qualidade de vida e do sono foram significantemente afetadas pela rinite, sendo os piores índices relacionados aos pacientes que atribuíram maior gravidade à doença. Ainda, limitações em atividades recreativas e domésticas devido à rinite se associaram a um sono de má qualidade. Não foi encontrada relação significativa entre sonolência diurna e qualidade de vida. Conclusão: os achados sinalizam a necessidade de orientar os pacientes quanto à higiene do sono, medidas de controle do ambiente e o efetivo tratamento medicamentoso. Também enfatizam a necessidade de avaliar as percepções singulares dos pacientes quanto à sua qualidade de vida para direcionar as estratégias de cuidado e monitorizar o tratamento e o controle da doença.

Introduction: the rhinitis is a common chronic respiratory disorder, highly prevalent in Brazil and worldwide, that mean a considerable onus for patients. It is associated with uncomfortable symptoms, wich reduce the quality of life and sleep, resulting in social, emotional and functional losses. Objective: to evaluate the quality of life and sleep according to degree of nuisance of patients with rhinitis being followed up in the Brazilian Unified National Health System (SUS) in the Western Bahia. Methods: a cross-sectional study that evaluated 169 patients between 12 and 90 years old diagnosed clinically with rhinitis, seen at an Otorhnolaryngology service in Barreiras (Bahia), between November 2018 and September 2019, through the Rhinoconjunctivitis Quality of Life Modified Questionnaire, Epworth Slipness Scale and Pittsburgh Sleep Quality Index. Results: quality of life and sleep were significantly affected by rhinitis, with the worst rates related to patients who attributed greater severity to the disease. Also, limitations in recreational and domestic activities due to rhinitis were associated with poor sleep. No significant relationship was found between daytime sleepiness and quality of life. Conclusion: the findings signal the need to guide patients on sleep hygiene, environmental control measures and effective pharmacological management. They also emphasize the need to assess patients' unique perceptions of their quality of life to guide care strategies and monitor the disease treatment and control.

OBJECTIVE@#To explore the correlation of temperament type and mother's emotional state with acute respiratory tract infections in children so as to provide evidence for comprehensive treatment of the infections.@*METHODS@#A total of 200 children aged between 3 and 6 were enrolled in this study from two kindergartens of Guangzhou and Hengyang. The mothers were invited to complete a questionnaire of the children's general information followed by assessment using children's temperament scale and the Depression-Anxiety-Stress Scale.@*RESULTS@#The total incidence of acute respiratory infection was significantly higher in children with a hard- to-raise temperament than the easy- to-raise children (P < 0.05); the incidences of acute rhinitis, acute pharyngitis, acute laryngitis and acute bronchitis were all significantly higher in the hard-to-raise children (P < 0.05). A significant positive correlation was identified between the total number of episodes of acute respiratory tract infection in children and their mothers' stress and anxiety levels (P < 0.01). Acute rhinitis and acute tracheitis in the children were both positively correlated with the mothers' stress scores (P < 0.05), while acute pharyngitis and acute laryngitis were positively correlated with the mothers' anxiety scores (P < 0.05), while acute bronchitis was positively correlated with the mothers' stress and anxiety scores (P < 0.05). Multiple linear regression analysis with the factors influencing the types of acute respiratory tract infections in children as the independent variables suggested that the easy-to-raise type of temperament was a protective factor against acute rhinitis in children (P < 0.05), while mothers' anxiety was a risk factor of acute laryngitis in children (P < 0.05); the mothers' stress was a risk factor for acute bronchitis in children (P < 0.05).@*CONCLUSION@#Acute respiratory tract infection in children is closely related to the temperament type of the children and the emotional state of the mothers, which are important therapeutic targets in comprehensive interventions of acute respiratory tract infection in children.

Objective: To explore the characteristics of neonatal adenoid development and to study the relationship between neonatal adenoid development and disease. Methods: A retrospective analysis of neonates who received an electronic rhinopharyngolaryngoscope at Shenzhen Children's Hospital from January 2019 to December 2020 was conducted to track the children's medical history and to analyze the adenoid development status. All 131 neonates successfully completed the electronic laryngoscopy. According to the presence or absence of visible adenoid hyperplasia, they were divided into a hyperplasia group (81 cases, 61.83%) and an un-hyperplasia group (50 cases, 38.17%). Results: Compared with the un-hyperplasia group, the age and birth weight of the adenoid hyperplasia group were larger, and the difference was statistically significant (Z age=-4.634,Z weight=-2.273,all P<0.05), but there was no significant difference in gender and gestational age between the two groups. The number of neonates with rhinitis/sinusitis in the hyperplasia group were significantly more than those in the un-hyperplasia group (62.96% vs 48%). Conclusion: The development of neonatal adenoids is related to daily age, birth weight, but not significantly related to gender and gestational age.

Objective: To compare the clinical characteristics and plasma inflammatory markers levels in different endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP), and to explore the plasma biomarkers associated with endotypes of CRSwNP. Methods: A total of 74 CRSwNP patients (male/female: 41/33; average age: 40 years) and 40 control subjects underwent septoplasty in Tongji Hospital from January 2015 to December 2017 were enrolled in this study. The demographic and clinical features of all subjects including age, gender, past history, visual analogue scale (VAS) and CT scores were recorded. Patients with CRSwNP were divided into EoshighNeuhigh, EoshighNeulow, EoslowNeuhigh and EoslowNeulow four endotypes according to the eosinophil (Eos) percentage and neutrophil (Neu) count of nasal polyps tissue. Preoperative blood routine was performed and the levels of 27 biomarkers in plasma were measured by Bio-Plex suspension chip method. The clinical characteristics and the level of serum biomarkers of patients with different endotypes were compared. SPSS 18.0 software was used for statistical analysis. Results: There was no difference in the clinical features including gender ratio, age, course of disease, VAS score, endoscopy and CT score among EoshighNeuhigh, EoshighNeulow, EoslowNeuhigh and EoslowNeulow CRSwNP patients. Compared with EoslowNeuhigh and EoslowNeulow CRSwNP patients, patients with EoshighNeuhigh and EoshighNeulow endotype demonstrated a higher prevalence of atopy, allergic rhinitis and asthma comorbidity, and increased peripheral blood eosinophil absolute count and percentage (all P<0.05). However, there was no significant difference between EoshighNeuhigh and EoshighNeulow CRSwNP. Plasma levels of all 27 mediators including type 1 cytokines (IL-12 and IFN-γ), type 2 cytokines (IL-4, IL-5 and IL-13), type 3 cytokines (IL-17A), pro-inflammatory cytokines (IL-6 and TNF-α) and tissue remodeling-related markers (bFGF, VEGF and PDGF-BB) demonstrated no significant difference among all endotypes of CRSwNP (all P>0.05). Conclusions: Eoshigh and Eoslow CRSwNP patients display significant differences regarding the prevalence of atopy, allergic rhinitis and asthma comorbidity, peripheral blood eosinophil absolute count and percentage, but the clinical characteristics, blood cellular and biological markers can not effectively distinguish four endotypes of CRSwNP. Further studies are warranted to dig out the potential objective, convenient and reliable markers associated with endotypes in patients with CRSwNP.

Objective: To detect the percentages of CD8+Treg cells in the nasal mucosa and peripheral blood of chronic rhinosinusitis (CRS) and to explore their correlation with eosinophilic infiltration. Methods: Thirty-three chronic rhinosinusitis with polyp (CRSwNP), 26 chronic rhinosinusitis without polyp (CRSsNP) and 27 control patients who were collected with the nose mucosal tissue and peripheral blood in the Third Affiliated Hospital of Sun Yat-sen University from March 2017 to October 2018 were selected, including 59 males and 27 females, aging from 18 to 72 years. Hematoxylin and eosin (HE) staining was used to observe the number of eosinophils in the nasal tissues and to classify the CRS into eosinophilic CRS (ECRS) and non-eosinophilic CRS (Non-ECRS). Flow cytometry was used to detect the percentages of CD4+ and CD8+T cells in lymphocytes of nasal mucosa and peripheral blood. The percentages of CD8+Foxp3+Treg cells, CD8+Foxp3-IL-10+Treg cells, CD8+IFN-γ+T cells (Tc1), CD8+IL-4+T cells (Tc2) and CD8+IL-17A+T cells (Tc17) in lymphocytes of nasal mucosa and peripheral blood were also tested. Besides, the percentages of Foxp3+TGF-β+Treg cells and Foxp3+IL-10+Treg cells in CD8+T cells were determined. All data were represented by M (IQR). GraphPad 7.0 and SPSS 16.0 were used for illustration and statistical analysis. Results: The percentage of CD8+T cells (37.75%(17.35%)) was higher than that of CD4+T cells (4.72%(4.29%)) in nasal mucosa (Z=-5.70, P<0.001), while lower (23.60%(9.33%)) than that of CD4+T cells (44.05% (10.93%)) in peripheral blood (t=9.72, P<0.001). CRSwNP patients possessed the highest Tc2 (1.82% (1.22%)) and Tc17 (1.93% (2.32%)) percentages than CRSsNP (Tc2: 0.84% (0.79%); Tc17: 0.54% (1.04%)) and control (Tc2: 1.09% (0.92%); Tc17: 0.47% (0.51%), both P<0.05) patients. While, CRSwNP patients possessed the lowest CD8+Foxp3+Treg cells percentage (0.10% (0.32%)) than CRSsNP (0.43% (1.45%)) and control (0.48% (0.83%), Z value was -2.24, -2.22, respectively, P value was 0.025, 0.027, respectively). The percentages of Foxp3+TGF-β+Treg cells and Foxp3+IL-10+Treg cells of CD8+T cells in nasal mucosa in CRSwNP were also lower than controls (Z value was 1.46, 0.49, respectively, both P=0.001). Moreover, the percentage of CD8+Foxp3-IL-10+Treg cells of CD8+T cells was decreased in nasal mucosa of CRSwNP patients (0.14% (0.28%)) when compared with that of CRSsNP (0.89% (0.81%), Z=0.61, P=0.03). ECRS patients had the lower percentages of CD8+Foxp3+Treg cells (0.07% (0.44%)) and CD8+Foxp3-IL-10+Treg cells (0.13% (0.21%)) than Non-ECRS patients (CD8+Foxp3+Treg cells: 0.53% (0.75%); CD8+Foxp3-IL-10+Treg cells: 0.29% (0.76%), t value was 2.14, 2.78, respectively, both P<0.05). The percentage of CD8+Foxp3+Treg cells and the ratio of CD8+Foxp3-IL-10+T per CD8+T cells were negatively correlated with the percentage of eosinophils in CRS patients(R2 value was 0.56, 0.78, respectively, both P<0.001). There was no significant difference in the distribution of CD8+Fxop3+Treg cells and CD8+Fxop3-IL-10+Treg cells in peripheral blood among different groups. Conclusion: The percentages of CD8+Treg cells decrease in CRSwNP patients, especially in ECRS patients, which are opposite to that of Tc2 and Tc17, and negatively correlate with the eosinophils percentage. This indicates that the decrease in the ratio of CD8+Treg cell may be associated with the immune-imbalance and eosinophilic infiltration in nasal mucosa of CRS patients.
