ABSTRACT
Abstract Introduction: Allergic rhinitis is a chronic inflammatory disease of the nasal mucosa, mediated by immunoglobulin E, affecting 1 in 6 individuals. The treatment aims at attaining symptomatic control with minimal side effects, a requirement for new alternative therapies, including phototherapy, as it has an immunosuppressive and immunomodulatory effect. Objective: To identify the effectiveness of phototherapy in the treatment of allergic rhinitis through a meta-analysis. Methods: We searched Web of Science, Scielo, PubMed, SCOPUS, PEDro, and LILACS databases, using the terms: ''intranasal irradiation'', ''phototherapy'' and ''allergic rhinitis''. The R software Metafor package was used for the meta-analysis and the effect size was calculated for each symptom individually. Results: All symptoms decreased considerably after phototherapy: rhinorrhea (ES• = -1.35; p < 0.0001; I2 = 91.84%), sneezing (ES• = -1.24; p < 0.0001; I2 = 91.43%), nasal pruritus (ES• = -1.10; p < 0.0001; I2 = 91.43%); nasal obstruction (ES• = -1.11; p < 0.0001; I2 = 91.88%). The effects were more significant in perennial allergic rhinitis than in the seasonal type. Conclusion: Considering the effect size and the statistical significance attained in our study, rhinophototherapy showed to be an effective treatment for reducing the nasal symptom scores triggered by AR.
Resumo Introdução: A rinite alérgica é uma doença inflamatória crônica da mucosa nasal, imunomediada por imunoglobulina E, que afeta 1/6 dos indivíduos. O tratamento visa o controle dos sintomas com efeitos colaterais mínimos, uma prerrogativa para novas terapias alternativas, como a fototerapia, por apresentar efeitos imunossupressor e imunomodulador. Objetivo: Identificar, mediante uma metanálise, a eficácia da fototerapia no tratamento da rinite alérgica. Método: Usamos as bases de dados: Web of Science, Scielo, PubMed, SCOPUS, PEDro e LILACS, com os termos de busca: intranasal irradiation, phototherapy, allergic rhinitis. Para a metanálise foi usado o pacote metafor do software R, o tamanho do efeito foi calculado para cada sintoma separadamente. Resultados: Todos os sintomas apresentaram diminuição significante após a fototerapia: coriza (ES =-1,35; p < 0,0001; I2 = 91,84%), espirros (ES =-1,24; p < 0,0001; I2 = 91,43%), prurido nasal (ES =-1,10; p < 0,0001; I2 = 91,43%); obstrução nasal (ES =-1,11; p < 0,0001; I2 = 91,88%), com efeitos mais expressivos na rinite alérgica perene do que na rinite alérgica sazonal. Conclusão: Considerando-se a magnitude do efeito e a significância estatística alcançadas em nosso estudo, a rinofototerapia demonstrou-se um tratamento eficaz para a redução dos escores dos sintomas nasais desencadeados pela rinite alérgica.

In the non-pollen season, the peripheral ILC2 cells in children with hay fever presented a decreasing trend [(11.30±2.45)%], but was still higher than that in HDM-sensitized asthmatics [(3.76±1.96)%, P<0.05] and HC [(1.32±0.91)%, P<0.05] at the same time point. Moreover, peripheral IL-13+ ILC2 cells in children with hay fever [(6.94±3.16)% vs(4.17±1.98)%, P<0.05] and in HDM-sensitized asthmatics [(1.89±0.70)% vs(1.44±0.55)%, P<0.05] during the pollen season were significantly higher than those in the non-pollen season. After the in vitro stimulation with IL25 or IL-33, the levels of IL-5 and IL-13 in culture supernatants were both increased in children with hay fever and HDM-sensitized asthmatics, and a synergistic action was observed when IL25 and IL-33 were used in combination. Meanwhile, the protein level of phospho-STAT4 in Lin- cells was significantly up-regulated in the hay fever group after stimulation with IL25 and IL-33.@*Conclusions@#During the pollen season, the abnormal number and function of ILC2 subpopulation in children with hay fever might be another cause of the occurrence of clinical symptoms in a short period of time or acute exacerbation.
ABSTRACT
Objective To analyze the dynamic changes in the expression and function of peripher-al typeⅡinnate lymphoid cell (ILC2) subpopulation and the activity of signal transducers and activators of transcription (STAT6) in children with hay fever during pollen season. Methods A total of 10 patients with hay fever, 10 patients with house dust mite ( HDM)-sensitized asthma and 12 healthy controls ( HC) were enrolled in this study. Changes in peripheral ILC2 and the intracellular expression of Th2-related cyto-kines were detected by flow cytometry during and outside the pollen season. Peripheral Lin- cell population was isolated from each group and cultured with the presence of IL-25 or IL-33 for 7 d. The concentrations of IL-5 and IL-13 in culture supernatants were measured by ELISA. Expression of phospho-STAT6 at protein level was quantified by Western blot. Results Within the pollen season, the percentage of peripheral ILC2 cells was significantly higher in children with hay fever [(23. 09±7. 86)％] than in children with HDM-sen-sitized asthma [(6. 84±3. 85)％, P<0. 05] and healthy children[(1. 69±0. 87)％, P<0. 05]. In the non-pollen season, the peripheral ILC2 cells in children with hay fever presented a decreasing trend [(11. 30±2. 45)％], but was still higher than that in HDM-sensitized asthmatics [(3. 76±1. 96)％, P<0. 05] and HC [(1. 32±0. 91)％, P<0. 05] at the same time point. Moreover, peripheral IL-13+ILC2 cells in children with hay fever [(6. 94±3. 16)％ vs(4. 17±1. 98)％, P<0. 05] and in HDM-sensitized asthmatics [(1. 89 ±0. 70)％ vs(1. 44±0. 55)％, P<0. 05] during the pollen season were significantly higher than those in the non-pollen season. After the in vitro stimulation with IL25 or IL-33, the levels of IL-5 and IL-13 in culture supernatants were both increased in children with hay fever and HDM-sensitized asthmatics, and a synergis-tic action was observed when IL25 and IL-33 were used in combination. Meanwhile, the protein level of phospho-STAT4 in Lin-cells was significantly up-regulated in the hay fever group after stimulation with IL25 and IL-33. Conclusions During the pollen season, the abnormal number and function of ILC2 subpopula-tion in children with hay fever might be another cause of the occurrence of clinical symptoms in a short period of time or acute exacerbation.
ABSTRACT
Objective To investigate the changes in percentage and function of CD4+CD25+regu-latory T cells ( Tregs) in peripheral blood of patients with hay fever. Methods A total of 20 patients with hay fever, 20 patients with house dust mite-induced allergic asthma and 20 healthy subjects were enrolled in this study. Peripheral blood samples were collected from all subjects to isolate PBMCs. Percentages of Tregs in PBMCs were measured by flow cytometry. CD4+CD25+ Tregs and CD4+CD25-T cells ( Teffs) were isola-ted by immunomagnetic cell sorting. Effects of CD4+CD25+Tregs on the proliferation of Teffs were evaluated by MTT assay. Expression of Foxp3 and TGF-β1 at mRNA level was analyzed by RT-PCR. Results During the pollen season, the percentage of circulating Tregs in patients with hay fever [(1. 82+0. 82)％] was sig-nificantly lower than that in patients with house dust mite-induced allergic asthma [(2. 96±1. 34)％] and health subjects [(5. 78±2. 29)％] (both P<0. 05). Expression of Foxp3 at mRNA level was significantly reduced in patients with hay fever (0. 46±0. 25) as compared with that of the house dust mite-induced aller-gic asthma (0. 64±0. 31) and healthy control (1. 04±0. 21) groups (both P<0. 05). Expression of TGF-β1 at mRNA level in both hay fever (0. 34±0. 27) and house dust mite-induced allergic asthma (0. 43±0. 31) groups was lower than that of the healthy control group (0. 99±0. 34). Treg-mediated suppression of Teff proliferation was significantly decreased in patients with hay fever [(17. 1±8. 4)％] as compared with that in patients with house dust mite-induced allergic asthma [(21. 4±9. 1)％]) and healthy subjects [(36. 0± 13. 9)％] (P<0. 05). Conclusion Decreased percentage and defective function of Tregs might be one of the major causes for the occurrence and development of hay fever in children during the pollen season.

ABSTRACT
BACKGROUND AND PURPOSE: Valproate is used as a prophylactic drug for migraine, but it is not be effective in all patients. We used medical records to investigate which clinical factors affected the response to valproate in patients with migraine as an original headache, and established a scoring system for predicting the clinical response to prophylactic therapy. METHODS: We investigated clinical factors from the medical records of 95 consistent responders (CRs) and 24 inconsistent responders (IRs) to valproate. RESULTS: Multivariate stepwise logistic regression analysis revealed that a history of hyperlipidemia and hay fever and the complication of depression or other psychiatric disorder were significant factors that independently contributed to a negative response, with odds ratios of 6.024 [no vs. yes; 95% confidence interval (CI)=1.616–22.222], 2.825 (no vs. yes; 95% CI=1.046–7.634), and 2.825 (no vs. yes; 95% CI=1.052–7.576), respectively. A predictive index (PI) of the clinical response to valproate in patients with migraine was calculated using the regression coefficients of these three factors as an integer, and the index was significantly higher for IRs than for CRs (1.46±1.10 vs. 0.69±0.74, mean±SD, p<0.001). CONCLUSIONS: The obtained PI may represent an appropriate scoring system for predicting the responses in these patients.

La primera parte de este artículo se dedicó a presentar las líneas de investigación biológica experimental que se realizan en la Homeopatía; ahora, esta segunda entrega se enfoca, de inicio, en la presentación y el análisis de 25 estudios de notable calidad metodológica que permiten evaluar científicamente la eficacia clínica de la medicina hahnemanniana. Cabe decir que a pesar de que la realización de estos trabajos es complicada y de que sus resultados varían, en conjunto nos ayudan a concluir que no es tan fácil afirmar, como una simple visión general, que la Homeopatía es un placebo. A continuación, el doctor Bernard Poitevin enlista las hipótesis que distintos grupos de científicos han tratado de corroborar o desmentir para dar respuesta a una de las interrogantes más frecuentes que se le plantean a la Homeopatía: cuál es el mecanismo de acción del medicamento homeopático (y, en consecuencia, qué tipo de información tiene y de qué manera interactúa con el organismo del paciente). Los resultados obtenidos hasta ahora no son concluyentes, ya que este tipo de investigaciones son todavía muy recientes. Finalmente, el autor nos recuerda que la Homeopatía es una disciplina evolutiva y, como tal, debe eludir los dogmatismos e incluso cuestionar sus principios fundamentales cuando sea necesario. Sólo a través de la investigación a fondo de aquellos problemas científicos que plantea la Homeopatía será posible acallar las críticas y, sobre todo, se tendrá un mejor conocimiento de esta disciplina médica, lo que en consecuencia mejorará su aplicación y efectividad...
The first part of this paper was dedicated to show the lines of experimental biological research being conducted in homeopathy; now, this second part focuses, at first, to the presentation and analysis of 25 studies of high methodological quality that allows to evaluate scientifically the clinical efficacy of Hahnemanns medicine. We can say that although the realization of these studies is complicated and that their results may vary, together they help us to conclude that it is not so easy to say, as a simple overview that homeopathy is a placebo. Then Dr. Bernard Poitevin lists the hypothesis that different groups of scientists have tried to corroborate or deny to answer one of the most frequent questions posed to homeopathy: what is the mechanism of action of homeopathic medicine (and therefore what type of information does it has and how it interacts with the patients body). The results so far are inconclusive, since this type of research is still very recent. Finally, the author reminds us that homeopathy is an evolving discipline and, as such, must avoid dogmatism and even to question its fundamental principles when necessary. Only through a profound research of those scientific problems that Homeopathy propose It will be possible to silence criticism and, above all, we will have a better knowledge of this medical discipline, which consequently will improve its implementation and effectiveness...

ABSTRACT
Objective To investigate the relationship between airborne pollen concentrations and the number of medical consultations in out-patient and emergency for respiratory diseases in Haidian district,Beijing. Methods To collect the data of airborne pollen concentrations,atmospheric concentrations of total suspended particles(TSP),the related meteorological factors (average temperature,maximum temperature,minimum temperature,average air pressure,precipitation and relative humidity) and the data of patients who were diagnosed with respiratory diseases including acute pharyngitis,acute laryngitis,acute bronchitis,anaphylactic rhinitis and bronchial asthma from database on medical insurance,from April to September in 2000 to 2002 in Haidian district,Beijing. The partial correlation coefficients between airborne pollen concentrations and the number of medical consultations for respiratory diseases in spring (from April 1st to June 16th),and in summer-autumn (from July 15th to September 30th) were calculated after controlling TSP concentrations and the six related meteorological factors. Results The airborne pollen concentrations in these three years showed two obvious peaks in spring and summer-autumn,and each of the five respiratory diseases has its specific change character. The number of medical consultations for anaphylactic rhinitis was significantly associated with the airborne pollen concentrations in summer-autumn (the partial correlation coefficient was 0.802,P
ABSTRACT
Objective To evaluate the effectiveness of allergen specific immunotherapy (SIT) in the treatment of allergic rhinitis. Methods A total of 132 patients with seasonal ragweed allergic rhinitis were enrolled in this study. The patients were randomly divided into two groups. SIT group, in which 68 patients were treated with ragweed SIT for six months before July for 3 years. ST (symptomatic therapy) group, in which 64 patients were treated with ST during seasonal symptomatic period. The healthy control group included 40 subjects. The levels of serum total IgE (tIgE), specific IgE (sIgE), ECP, IgG and IL-4, IL-5, IFN-? were measured, and eosinophil numbers were counted. The symptom score, lung-function test and skin prick test were performed before and after the treatment. Results The elevated levels of tIgE, ECP, IL-4, IL-5 in the sera and eosinophil counts in peripheral blood of the patients were significantly reduced, whereas the levels of IgG and IFN-? were increased following SIT. The levels of serum sIgE were not changed in both SIT and ST groups. 30.88% of the patients were clinically cured, the effective rate was 41.18%, the improvement rate was 20.59% after SIT, and only in 7.39% of patients there was no clinical improvement. In 16.18% of patients there were mild side effects to SIT. In the ST group, there was on change in all the laboratory results and clinical symptoms, and 25% of the patients developed asthma. Conclusion SIT was able to improve the symptoms and laboratory results of the patients with allergic rhinitis. The results indicated that SIT may be an effective and safe therapy for patients with allergic rhinitis.
