The efficacy and safety of ciclesonide for the treatment of perennial allergic rhinitis: a systematic review and meta-analysis / Eficácia e segurança da ciclesonida no tratamento da rinite alérgica perene: uma revisão sistemática e metanálise

Abstract Introduction: Allergic rhinitis is a chronic inflammatory disease which affects 1 out of 6 individuals. Perennial allergic rhinitis accounts for 40% of AR cases. Ciclesonide is one of the relatively new intranasal steroid for allergic rhinitis. Objective: The purpose of this study was to evaluate the efficacy and safety of ciclesonide in the treatment of perennial allergic rhinitis. Methods: We searched Pubmed, Scientific Citation Index, Embase, Clinical Trial Registries for randomized controlled trials and Cochrane Central Register of Controlled Trials to find out the randomized controlled Trial comparing ciclesonide with placebo for PAR. Results: Eight studies were included. In comparison with placebo groups, ciclesonide groups significantly decreased Reflective Total Nasal Symptom Score (MD = −0.56; 95% CI −0.72 to 0.39, p < 0.00001) with heterogeneity (p = 0.19, I2 = 24%), Instantaneous Total Nasal Symptom Score (MD = −0.57; 95% CI −0.75 to −0.39, p < 0.00001) with heterogeneity (p = 0.34, I2 = 11%). A significant effect for Reflective Nasal Symptom Score Subtotal (MD = −0.15; 95% CI −0.18 to −0.13, p < 0.00001) with heterogeneity (p = 0.12, I2 = 24%) was also demonstrated. Rhinoconjunctivitis quality of life questionnaire score (RQLQs) (MD = −0.27; 95% CI −0.39 to −0.15, p < 0.00001) with heterogeneity (p = 0.58, I 2 = 0%) in the treatment of ciclesonide was also significantly reduced. In addition, the difference in Treatment-Emergent Adverse Events between the two groups was not significant. Conclusion: Ciclesonide can improve perennial allergic rhinitis without increasing adverse events. Ciclesonide may be another valuable choice for perennial allergic rhinitis in the future.

Resumo Introdução: A rinite alérgica é uma doença inflamatória crônica que afeta um a cada seis indivíduos. A rinite alérgica perene é responsável por 40% dos casos de rinite alérgica. A ciclesonida é um dos corticosteroides intranasais mais novos para o tratamento dessa condição clínica. Objetivo: Avaliar a eficácia e segurança da ciclesonida no tratamento da rinite alérgica perene. Método: Uma busca foi feita nos bancos de dados Pubmed, Scientific Citation Index, Embase e Clinical Trial Registries por ensaios clínicos randomizados e Cochrane Central Register of Controlled Trials por estudos controlados randomizados que comparassem ciclesonida com placebo no tratamento da rinite alérgica perene. Resultados: Oito estudos foram incluídos. Em comparação com os grupos placebo, os grupos ciclesonida mostraram diminuição significante no escore do Reflective Total Nasal Symptom Score (DM = −0,56; IC 95%: −0,72 a −0,39, p < 0,00001) com heterogeneidade (p = 0,19, I2 = 24%), do Instantaneous Total Nasal Symptom Score (DM = −0,57; IC95%: −0,75 a −0,39, p < 0,00001) com heterogeneidade (p = 0,34, I2 = 11%). Um efeito significante no escore do Reflective Nasal Symptom Score Subtotal (DM = −0,15; IC 95%: −0,18 a −0,13, p < 0,00001) com heterogeneidade (p = 0,12, I2 = 24%) também foi demonstrado. O escore do Rhinoconjunctivitis Quality of Life Questionnaire score (RQLQs) (DM = −0,27; IC 95%: −0,39 a −0,15, p < 0,00001) com heterogeneidade (p = 0,58, I2 = 0%) também foi significantemente reduzido no tratamento com ciclesonida. Além disso, a diferença em relação aos eventos adversos emergentes do tratamento entre os dois grupos não foi significante. Conclusão: A ciclesonida pode melhorar a rinite alérgica perene sem aumentar os eventos adversos. Esse fármaco pode ser outra opção valiosa para a rinite alérgica perene no futuro.

Anticuerpo monoclonal anti-inmunoglobulina E en el tratamiento de la rinitis alérgica / Anti-immunoblobulin E monoclonal antibody in the treatment of allergic rhinitis

La rinitis alérgica (RA) es una enfermedad con alta incidencia a nivel mundial, sus síntomas están directamente relacionados con la exposición a un alérgeno ambiental que desencadena una cascada inflamatoria mediada por inmunoglobulina E. El tratamiento convencional actual de la RA consta del control ambiental, farmacoterapia e inmunoterapia; la reciente aparición de los anticuerpos monoclonales para el manejo de las enfermedades alérgicas parece ser prometedora. Estudios han demostrado que el Omalizumab, un anticuerpo monoclonal humanizado anti IgE, es capaz de modificar la respuesta inflamatoria dependiente de IgE, constituyéndose en una posible alternativa al manejo de la RA.

Allergic rhinitis (AR) is a disease with global high prevalence, its symptoms are directly related to environmental exposure to an allergen that triggers an inflammatory cascade mediated by Immunoglobulin E. The current standard treatment of AR consists of environmental control, pharmacotherapy and immunotherapy; the recent emergence of Monoclonal Antibodies for the management of allergic diseases appears promising. Studies have shown that Omalizumab, an anti-IgE humanized monoclonal antibody, is capable of modify the inflammatory IgE-dependent response, becoming a possible alternative to the management of AR.

Uso de probióticos na rinite alérgica / Probiotics in allergic rhinitis

Probióticos são microrganismos viáveis, usados como suplemento alimentar, normalmente bactérias ácidas lácticas, que podem modificar a composição e/ou a atividade metabólica da microbiota intestinal, modulando o sistema imune de forma que beneficie a saúde do indivíduo. OBJETIVO: Fazer uma revisão sobre o uso de Probióticos (Lactobacillus e Bifidobacterium) na rinite alérgica. MATERIAL E MÉTODO: Foram pesquisados artigos originais no Pubmed. RESULTADOS: Os resultados encontrados indicam que os probióticos, Lactobacillus e Bifidobacterium parecem prevenir as recorrências alérgicas, aliviar a severidade dos sintomas e promover melhora da qualidade de vida dos pacientes com rinite alérgica. Estes efeitos ocorrem devido à modulação do sistema imunológico através da indução da produção de citocinas que promovem uma resposta TH1 dominante em alérgicos, através do efeito da modulação no balanço TH1/TH2. CONCLUSÃO: O uso de bactérias probióticas pode ser uma forma efetiva e segura de prevenção e/ou tratamento de rinite alérgica, mas seu mecanismo exato de ação permanece desconhecido. No entanto, estudos clínicos usando probióticos e intervenção dietética deverão ser o foco de futuras investigações, para permitir um uso mais amplo.

Probiotics are live microorganisms used as supplementary food, usually lactic acid bacteria that can change either the composition and/or the metabolic activities of the gut microbiota modulating the immune system in a way that benefits the person's health. AIM: To review the use of Probiotics (Lactobacillus and Bifidobacterium) in allergic rhinitis patients. MATERIALS AND METHODS: Pubmed original articles were used as data source. RESULTS: Results indicate that probiotics, Lactobacillus and Bifidobacterium appear to prevent allergy recurrences, alleviate the severity of symptoms and improve the quality of life of patients with allergic rhinitis. This happens because of the immune system modulation through the induction of cytokine production which cause a dominant TH1 response in allergic patients by modulating the TH1/TH2 balance effect. CONCLUSION: The use of probiotic bacteria could be an effective and safe way to prevent and/or treat allergic rhinitis, but its underlying mechanisms remain unclear. Therefore, clinical studies using probiotics and dietary intervention should be the focus of future research to enable a more widespread use.

Co-administration of Chenopodium album allergens and CpG oligodeoxy- nucleotides effects on peripheral blood mononuclear cells of patients with allergic rhinitis treated with intranasal corticosteroids and antihistamines

Allergic Rhinitis [AR] is one of the most common chronic diseases in the developed countries. This study was performed to investigate the effect of CpG-ODN in alteration of T-helper [Th]l/Th2 balance of patients with AR treated with intranasal corticosteroids [INCs] and antihistamines. Peripheral blood mononuclear cells [PBMCs] of 20 patients with AR were isolated before and after 45 days therapy. Cytokine production [IL-4, IL-10, IL-13, IFN-gamma] and specific Ch.a IgE in response to CpG co-administration of natural chenopodium album [CpG/Ch.a] or recombinant Ch.a [CpG/rCh.a] allergen were investigated in supernatants.of cultured PBMCs using ELISA Intracellular IL-10 was also assessed in CD4[+] cells using flow cytometry. Significant increase in production of IFN-y and IL-10 and decrease in production of IL-4 were found in supernatants of cultured PBMCs activated with CPG/ch.a and CPG/rch.a. of both CpG/Ch.a and CpG/rCh.a compared to allergens alone, before and after therapy. After therapy, IFN-gamma production with CpG/Ch.a was significantly increased in comparison with before [237 vs. 44 pg/ml, p=0.001]. IFN-gamma and IL-10 production with CpG/rCh.a was significantly increased after therapy compared to before [407.6 vs. 109 pg/ml, p=0.0l for IFN- gamma; 171.7 vs. 52.6 pg/ml, p=0.008 for IL-10], whilst IL-4 was significantly decreased [2.1 vs. 5.8 pg/ml, p=0.02]. Intracellular IL-10 expression was also significantly increased in response to either CpG/Ch.a or CpG/rCh.a that showed intracellular assay could be more sensitive than ELISA. Also, treatment with intranasal corticosteroids and antihistamines could enhance this CpG effect, in vitro

O impacto do tratamento fonoaudiológico no controle da asma e da rinite alérgica em crianças e adolescentes respiradores orais / The impact of speech therapy on asthma and allergic rhinitis control in mouth breathing children and adolescents

OBJETIVO: Detectar o impacto do tratamento fonoaudiológico no controle da asma e da rinite alérgica em crianças e adolescentes respiradores orais. MÉTODOS: Trata-se de um estudo quase-experimental; foram randomizados 24 pacientes com asma, rinite alérgica e respiração oral, idade de 6 a 15 anos. Todos os pacientes usavam dipropionato beclometasona inalação oral. No momento em que aceitaram participar da pesquisa, a inalação oral foi substituída pela inalação exclusivamente nasal na inspiração e, após 1 mês, associou-se ao tratamento fonoaudiológico em metade dos pacientes. Esses receberam 16 sessões de tratamento fonoaudiológico em 8 semanas, além do dipropionato de beclometasona inalação exclusivamente nasal (grupo DBF). O grupo de comparação recebeu somente dipropionato beclometasona inalação exclusivamente nasal (grupo DBI). Os dois grupos foram avaliados em cinco tempos. Utilizou-se o escore clínico da rinite alérgica, da asma, o protocolo de avaliação miofuncional orofacial adaptado de Marchesan (2003), a observação dos responsáveis, dados de espirometria, de pico de fluxo inspiratório e de pico de fluxo expiratório. RESULTADOS: Houve melhora significativa do grupo DBF: escores clínicos da asma no tempo 5 (p = 0,046); valores do pico de fluxo inspiratório no tempo 4 (p = 0,030); pico de fluxo expiratório no tempo 3 (p = 0,008); modo respiratório e postura de lábios (p = 0,000) a partir do tempo 3; observação dos responsáveis, no tempo 2, tempo 4 e tempo 5 (p = 0,010; p = 0,027; p = 0,030). CONCLUSÕES: O tratamento fonoaudiológico associado ao dipropionato beclometasona por inalação exclusivamente nasal promoveu um controle clínico e funcional mais precoce e duradouro da asma, da rinite alérgica e da respiração oral entre os grupos estudados.

OBJECTIVE: To determine the impact of speech therapy on asthma and allergic rhinitis control in mouth breathing children and adolescents. METHODS: This was a quasi-experimental randomized study of 24 mouth breathing patients with asthma and allergic rhinitis, aged from 6 to 15 years. All patients were taking beclomethasone diproprionate through oral inhalation at the start of the study. At enrollment on the study, oral inhalation was substituted with exclusively nasal inhalation and 1 month later half of the patients began speech therapy. They attended 16 speech therapy sessions in 8 weeks and continued taking beclomethasone dipropionate through exclusively nasal inhalation (BDT group). The comparison group received only beclomethasone diproprionate through exclusively nasal inhalation (BDI group). Both groups were assessed five times. Clinical scores were calculated for allergic rhinitis and asthma, an adapted version of the Marchesan orofacial myofunctional assessment protocol was applied, and parents/guardians' observations were recorded, in addition to spirometry measurements of peak inspiratory and peak expiratory flow. RESULTS: There were significant improvements in the BDT group: clinical asthma score at T5 (p = 0.046); peak inspiratory flow at T4 (p = 0.030); peak expiratory flow at T3 (p = 0.008); breathing mode and lip position (p = 0.000) from T3 onwards; and parents/guardians' observations at T2, T4, and T5 (p = 0.010; p = 0.027; p = 0.030). CONCLUSIONS: Speech therapy in combination with beclomethasone diproprionate through exclusively nasal inhalation resulted in earlier and longer-lasting clinical and functional control of asthma, allergic rhinitis, and mouth breathing than was achieved in the group that only took beclomethasone diproprionate.

Futura study: evaluation of efficacy and safety of rupatadine fumarate in the treatment of persistent allergic rhinitis / Estudo futura: avaliação da eficácia e segurança do fumarato de rupatadina no tratamento da rinite alérgica persistente

Allergic rhinitis affects 10-30 percent of the population, negatively impacting one's quality of life and productivity. It has been associated with sinusitis, otitis media, sleep disorders, and asthma. Rupatadine is a second generation antihistamine with increased affinity to histamine receptor H1; it is also a potent PAF (platelet-activating factor) antagonist. It starts acting quite quickly, offers long lasting effect, and reduces the chronic effects of rhinitis. AIM: this study aims to assess the efficacy and safety of rupatadine in the treatment of persistent allergic rhinitis. MATERIALS AND METHOD: this is a multi-centric open prospective study. This study included 241 patients from 13 centers in Brazil and was held between October of 2004 and August of 2005. Signs and symptoms of rhinitis and tolerance to medication were analyzed after one and two weeks of treatment. RESULTS: reduction on general scores from 8.65 to 3.21 on week 2 (p<0.001). All signs and symptoms improved significantly in the first day of treatment (p<0.001), except for nasal congestion and secretion, which improved from the second day of treatment (p<0.001). Adverse events occurred in 19.9 percent of the cases, 27.7 percent on week 1. CONCLUSION: rupatadine effectively controls persistent allergic rhinitis; it is safe and presents low incidence of side effects.

A Rupatadina é um anti-histamínico de segunda geração, com elevada afinidade ao receptor histamínico H1 e potente inibição do fator ativador plaquetário (PAF). Tem rápido início de ação, longa duração e reduz os efeitos crônicos da rinite. OBJETIVO: Avaliar a eficácia e segurança da rupatadina no tratamento da rinite alérgica persistente. MATERIAL E MÉTODO: Estudo multicêntrico, aberto, prospectivo. Foram selecionados 241 pacientes em 13 centros no Brasil durante o período de outubro de 2004 a agosto de 2005. Foram analisados os sinais e sintomas da rinite e a tolerabilidade após 1 e 2 semanas. RESULTADOS: Redução do escore geral de 8,65 para 3,21 na semana 2 (p<0,001). Todos os sinais e sintomas melhoraram significativamente, e no primeiro dia de tratamento (p<0,001), com exceção da obstrução e secreção nasal, a partir do segundo dia (P<0,001). A frequência de eventos adversos foi 19,9 por cento, sendo 27,7 por cento na 1ª semana. CONCLUSÕES: A rupatadina é eficaz no controle da rinite alérgica persistente, é segura e apresenta baixos índices de efeitos colaterais.

Efficacy of montelukast and loratadine as treatment for allergic rhinitis in children.

The objective of this study was to compare the effectiveness of montelukast combined with loratadine once daily to loratadine alone for a 2-week treatment course of allergic rhinitis in a randomized, double-blind placebo controlled trial which enrolled 115 children, 6- 15-years-old. The patients were randomly assigned to receive montelukast and loratadine (treatment group) or placebo and loratadine (control group). The primary outcome was the mean percent change of the total daytime nasal symptom scores (PDTS) and secondary outcomes were the mean percent changes of the nighttime nasal, daytime eye and composite symptom scores (PNTS, PES, PCS), as well as the nasal secretion, turbinate swelling and nasal congestion scores (PNSS, PTSS, PNCS). There were no significant differences in the PDTS of the 2 groups. The change in the night time nasal congestion score (PNTS-congestion) was higher in the treatment group, but not statistically significant (p = 0.077). Only the mean percent change in decreased turbinate swelling was significantly greater in the montelukast and loratadine group than the loratadine alone group (-22 +/- 7 vs. -1 +/- 5, p < 0.05).

Rinite alérgica: aspectos epidemiológicos, diagnósticos e terapêuticos: [revisão] / Allergic Rhinitis: epidemiological aspects, diagnosis and treatment: [review]

Este estudo tem como objetivo revisar a literatura a respeito da rinite alérgica quanto aos aspectos epidemiológicos, clínicos, diagnósticos e terapêuticos. A revisão da bibliografia foi realizada utilizando-se as bases de dados Medline, Literatura Latino-Americana e do Caribe em Ciências da Saúde e HighWire, nos últimos trinta anos, utilizando-se os descritores allergic rhinitis, epidemiology, diagnosis, e treatment. Foram selecionados 60 artigos. Este estudo destaca o aumento na prevalência da rinite alérgica, sua associação com a asma, os critérios diagnósticos e seu tratamento. A classificação da rinite alérgica é apresentada, bem como as estratégias de tratamento. As modalidades terapêuticas apresentadas e discutidas são anti-histamínicos, corticóides, imunoterapia, antileucotrienos, cromoglicato dissódico e anticorpos anti-IgE, bem como a redução da exposição aos alérgenos. Finalmente, ressalta-se a importância da abordagem da rinite alérgica em saúde pública.

This study was a review of the literature on the epidemiological, clinical, diagnostic and therapeutic aspects of allergic rhinitis. Bibliographic searches were based on the information contained within the Medline, Latin American and Caribbean Health Sciences Literature and HighWire databases, covering the last thirty years and using the following search terms: 'allergic rhinitis', 'epidemiology', 'diagnosis' and 'treatment'. Sixty articles were selected. This study describes the increase in the prevalence of allergic rhinitis, its relationship with asthma, the diagnostic criteria and the treatment. The classification of allergic rhinitis and strategies for its treatment are presented. Therapeutic modalities presented and discussed include the administration of antihistamines, corticosteroids, immunotherapy, anti-leukotrienes, sodium cromoglycate and anti-IgE antibodies, as well as minimizing exposure to inhaled allergens. Finally, the importance of the management of allergic rhinitis in public health is emphasized.

Circadian rhythms: chronotherapeutic study of non sedating antihistamines in treating allergic Rhinitis

The first aim of this study is to determine if there is circadian rhythm variation in persistent allergic rhinitis symptoms. The second aim is to evaluate the role of morning vs. evening non-sedating antihistamine therapy in achieving the improvement of these symptoms. One hundred patient suffering from allergic rhinitis symptoms were included in this study. A questionnaire regarding allergic rhinitis symptom was filled for each patient. Five symptoms [nasal itching, runny nose, nasal blockage, sneezing and eye symptoms] were graded from 0 to 3 [no, mild, moderate and sever respectively] with total symptom score equals 15. This questionnaire was filled before therapy. The patients were randomly divided into two groups, one group received non-sedating antihistamine once daily [cetirizine hydrochloride 10 mg or desloratidine 5 mg] at morning [AM-group] and the other one received the same antihistamine at evening [PM-group]. The same questionnaire was filled again after 2 weeks for each patient. Both Binomial Method and Kolmogorov-Smirnov Test [non-parametric tests] indicate that there was a significant difference between the total scores of symptoms at morning [AM] and night [PM]. P-Value of any of the two tests was less than 0.05. Using Spearman Rank Correlation, any symptom tends to lower its intensity during night. After treatment, using Kolmogorov-Smirnov test, TSS in PM-group is very significantly lower than that of AM-group. The adverse events were comparable in both groups and also comparable for cetirizine and desloratidine. The commonest side effects were gastro-intestinal upset [nausea and abdominal discomfort] in 13 patients [13%] and headache in 11 patients [11%]. The present study confirmed the morning versus evening variation of allergic rhinitis symptoms. The symptoms were more worse in the early morning. Giving antihistamine medication at night has a better therapeutic outcome in most of the patients. However, the timing of treatment must be individualized to each patient according to his own symptoms' circadian rhythm

Comparative efficacy of steroid nasal spray versus antihistamine nasal spray in allergic rhinitis.

This prospective randomized case controlled study was conducted to determine the efficacy of antihistamine (azelastine) nasal spray and compare it to steroid (beclomethasone) nasal spray on the symptoms of allergic rhinitis. Seventy five symptomatic patients of allergic rhinitis were included in this study. Diagnosis was made on the basis of history and physical examination. The patients were divided into three groups randomly. Group A was treated with Azelastine nasal spray, Group B was treated with Beclomethasone nasal spray and Group C was control group and only treated with steam inhalation. Efficacy of the treatment was assessed in the terms of Total Rhinitis Symptom Complex (TSC) scores and individual symptom score which was calculated on the basis of Okuda's grading system. Base line total symptom complex (TSC) scores were reduced in group A and group B by 84.0% after 4 week treatment whereas in group C it was reduced by only 38.0%. Decrease in mean score for sneezing was 95.0% in group A and group B whereas it was only 28.3% in group C. Similarly decrease in mean score for rhinorrhoea in azelastine group was 94.4% and in beclomethasone group was 95.3% in comparison to steam inhalation group where it was 25.0%. Only the beclomethasone reduced nasal stuffiness score significantly by 95.0%. No significant adverse effects of the drugs were observed. The present study establishes the relative efficacy and tolerability ofazelastine nasal spray as compared to beclomethasone nasal spray in symptomatic patients of allergic rhinitis.

[ comparative study of two treatment protocols in short course control of symptoms of allergic rhinitis patients]

Allergic rhinitis is the most common allergic disorder and its prevalence appears to be increasing. For writing prescription we have to consider some points: efficacy, safety and affordability of drugs and compliance of patient. According to the direct costs of allergic rhinitis, we selected two treatment protocols for comparison. 15 to 65 years-old patients suffered from clinical allergic rhinitis at least from one year ago [with annual not seasonal signs and symptoms] referred to Emam Reza hospital arranged in two treatment groups sequentially. After recording the first part of the questionnaire [about their symptoms] treatment started with two protocols. The first was less expensive one included first-generation antihistamine [Chlorpheniramin] and systemic decongestant [Pseudoephedrine] and the second more expensive one consisted of secondgeneration antihistamine [Loratadine] with inhaled corticosteroid [Beclomethasone]. After 45 days the second part of the questionnaire was completed. The patients who changed their jobs during this period were omitted from study. The two protocols were compared with each others by statistics software. Two protocols had similar efficacy on improvement of symptoms such as rhinorrhea, nasal or pharyngeal dryness and itching nasal congestion, PND and sneezing. According to the high price of second protocol and same efficacy of two protocols in some situations such as lack of drug affordability and patients' preference if there are no contraindications the first protocol could be a good alternative for second one

Rinite, sinusite e asma: indissociáveis? / Rhinitis, Sinusitis and Asthma: hard to dissociate?

Este estudo tem como objetivo rever a literatura ressaltando aspectos epidemiológicos e fisiopatológicos relacionados à abordagem unificada de rinossinusite alérgica e da asma, com as respectivas implicações terapêuticas. O levantamento bibliográfico foi realizado a partir das informações disponibilizadas pelas bases de dados Medline, MD Consult, Highwire, Medscape, LILACS e por pesquisa direta, dos últimos trinta anos, utilizando-se os termos allergic rhinitis e asthma. Foram selecionados 55 artigos originais em revisão não sistemática abordando a questão da associação clínica entre rinossinusite alérgica e asma. Verifica-se que nos últimos anos, com o uso de medicamentos tópicos, para as vias aéreas superiores ou para as vias aéreas inferiores, a abordagem terapêutica tem sido distinta. Entretanto, inúmeros inquéritos epidemiológicos, estudos de imunopatologia e clínicos demonstram a inter-relação entre asma e rinossinusite alérgica evidenciados por: i) a rinite alérgica encontra-se associada à asma e constitui-se em fator de risco independente para o seu aparecimento; ii)as características imunopatológicas da rinite alérgica e da asma são semelhantes; iii)a rinite alérgica e a asma são manifestações de uma enfermidade sistêmica; iv)o controle da rinite favorece o controle da asma. A estreita associação entre a rinite alérgica e a asma requer a integração das abordagens diagnóstica, terapêutica e profilática dessas enfermidades. Opções terapêuticas que permitam o controle simultâneo de ambas oferecem vantagens relacionadas ao custo e à tolerabilidade.

The objective of this study was to review the literature and to discuss epidemiological and physiopathological aspects and therapeutical implications of an unified approach to allergic rhinosinusitis and asthma. The bibliographic survey was based on the information provided by the following databases: Medline, MD Consult, Highwire, Medscape, LILACS and through direct search over thirty years, using the terms allergic rhinitis and asthma. Fifty-five original articles were selected in the no systematically review addressing the issue of clinical association between allergic rhinusinusitis and asthma. It is noteworthy that in the late years, with the use of specific topical medications for the lower airways or else, to the upper airways, the therapeutical approach has been distinct. However, numerous epidemiological surveys, immunopatological and clinical studies demonstrate the inter-relationship between asthma and allergic rhinossinusitis, characterized by: i) allergic rhinitis is associated to asthma and constitute an independent risk factor for its occurrence; ii) the immunopathological characteristics of allergic rhinitis and asthma are similar; iii) allergic rhinitis and asthma are manifestations of a systemic disease; iv) control of rhinitis favors asthma control. taking into consideration the close inter-relationship between allergic rhinitis and asthma, the approach to diagnosis, treatment and prophylaxis of these illnesses should be integrated. Therapeutical options that allow for the simultaneous control of asthma and allergic rhinitis offer advantages related both to costs and tolerability.

Evaluation of six years allergen immunotherapy in allergic rhinitis and allergic asthma

Allergen immunotherapy involves the administration of gradually increasing quantities of specific allergens to patients with IgE-mediated conditions until a dose is reached that is effective in reducing disease severity from natural exposure. In the present study we evaluated a period of six years immunotherapy allergic rhinitis and allergic asthma patients with positive skin prick test of common aeroallergen. The immunotherapy was performed on 156 patients. One hundred twenty of the cases were allergic rhinitis [80%], 29 cases had allergic asthma and 7 cases were mixed [4.5%]. 70% in allergic rhinitis group, 75% in allergic asthma group and 42.8% in mixed group completely improved. Immunotherapy, an older therapeutic method, has now been updated, and with appropriate indications, precautions and methods, has been clearly shown to be effective in the treatment of allergic rhinitis and in some cases of asthma and insect hypersensitivity

The efficacy and safety of 30 mg fexofenadine HCl bid in pediatric patients with allergic rhinitis.

Allergic rhinitis is one of the most common chronic disorders in children. It is also one of the most common causes of absence from school. This study reports on the efficacy and safety of a twice-daily oral dose of fexofenadine HCl 30 mg in Asian children aged 6-11 years diagnosed with seasonal or perennial allergic rhinitis. A total of 100 children with a history of allergic rhinitis for more than one year and a positive prick skin test response to at least one of the common aeroallergens in Thailand were enrolled in this multi-center, open-label, non comparative study. The severity of individual symptoms such as sneezing, rhinitis, etc. and adverse events were recorded in diary cards by the patients in form of scores as well as by the investigator at each visit. The total symptom score (TSS) with or without blocked nose at baseline, week 1 and week 2 was recorded. The TSS was defined as the sum of the individual symptom scores except for the nasal blockage score, as nasal blockage was not expected to respond to antihistamine treatment. Only patients with a total symptom score > or = 6 were included in the study. There was a statistically significant improvement at p < 0.01 for the TSS with or without blocked nose and for each symptom score such as blocked nose, sneezing, rhinorrhea, itchy nose/palate and/or throat, and itchy/watery/red eyes from baseline to week 1 and week 2. Additionally, there was a statistically significant improvement between week 1 and week 2 for itchy nose/palate and/or throat and itchy/watery/red eyes (p < 0.05). The Kappa measure of agreement was statistically significant at p < 0.001 between investigator's and patient's/parent's assessment, indicating the same degree of satisfaction with the overall effectiveness of the treatment. Fexofenadine 30 mg bid is effective in reducing the total symptom score of allergic rhinitis including blocked nose and is generally well tolerated. It is not cardiotoxic and is safe for pediatric patients as young as 6 years of age.

No effect of interleukin-2 on IgE levels given in addition to antiretroviral therapy in HIV-infected adults with CD4 >300 cells/mm3.

HIV-infected patients may have frequent atopy caused by an imbalance of Th1 and Th2 cytokines. The objective of the present study was to investigate whether IL-2 given in addition to antiretrovirals (ARV) would result in lower IgE levels and less allergic symptoms. Patients naive to IL-2 (n=28) began IL-2 plus ARV and were followed for 12 months. IgE, eosinophil and CD4 counts, HIV RNA, symptom scoring, PFT and skin prick test (SPT) were performed. It was found that the baseline median CD4 and IgE were 386.5 cells/mm3 and 63.5 IU/ml, respectively. Four patients had allergic rhinitis (AR) and 61% had a positive SPT to at least 1 antigen. At month 12, patients had higher CD4 counts (p < 0.001) compared to the baseline; however, there were no differences in IgE levels, allergic symptom scores or HIV RNA. The eosinophil count was higher after IL-2 administration. It was concluded that IL-2 plus ARV resulted in higher CD4 counts but had no effect on atopy.

Comparison of the efficacy of inhaled budesonide and oral choline in patients with allergic rhinitis

A single blind parallel group study was conducted to evaluate the effects of oral choline [given as tricholine citrate [TRI]] in patients with allergic rhinitis, and compare its efficacy with intranasal budesonide [BUD]. The study was conducted at the Department of Respiratory Medicine, Vallabhbhai Patel Chest Institute, Delhi, India from February 2001 to April 2002. Sixty patients were randomized into 2 groups after a run-in period of 2 weeks. Group A received intranasal BUD 200 mg twice daily and group B received TRI 500 mg thrice daily. The patients were reviewed every 2 weeks up to 8 weeks. The mean individual symptom score, total symptom score and drug score were significantly reduced in both groups [p<0.05] compared to baseline values, with maximum effect occurring within 4 weeks of therapy. Budesonide showed statistically significant reduction [p<0.05] in all the outcome parameters, when compared to TRI. Crossover study between the 2 treatment groups also showed similar results. Seventy-six% of patients with BUD and 43% of patients with TRI found the drug to be effective. Both intranasal BUD and oral TRI are effective in relieving symptoms of allergic rhinitis. Budesonide was found to be the statistically superior drug

Rinitis alérgica y rinosinusitis: una revisión necesaria / Allergic rhinitis and rhinosinusitis: a necessary review

La importancia de las enfermedades alérgicas, y entre ellas de la rinitis alérgica, así como su costo económico y de recursos humanos, tanto como su prevalencia, está fuera de toda duda. Esta entidad representa la sexta causa de enfermedad crónica en EE.UU. y tiene un gran impacto en la calidad de vida de los pacientes que la padecen. La rinitis alérgica es un desorden heterogéneo y su alta prevalencia es aún subdiagnosticada. Está caracterizada por uno o más de los siguientes síntomas: estornudos, picor nasal, secreción y congestión nasal. Muchos agentes están involucrados con esta entidad, entre ellos, pólenes, hongos, ácaros y animales domésticos. Atendiendo a que la rinitis y la sinusitis mantienen síntomas en común como la pérdida del olfato y la obstrucción y el drenaje nasal, se prefiere denominarla como rinosinusitis. Muchos estudios han identificado a la rinitis como un factor de riesgo para el asma, con una prevalencia entre 80 y 90 por ciento. Esta revisión pretende repasar aspectos fundamentales de estas entidades como definición, etiología, clasificación, síntomas y tratamiento, y servir de guía para aquellos médicos que de una forma u otra tratan ambas afecciones con un impacto demostrado en la calidad de vida de los que las padecen
