Identificação de novos alérgenos de pólen do cajueiro (Anacardium occidentale L.) para auxílio no diagnóstico e futura otimização do tratamento / Identification of novel allergens of cashew pollen

Figo, Daniele Danella 28 June 2017 (has links)
A polinose é uma rinite alérgica sazonal que acontece pela sensibilização por pólens. Possui periodicidade anual, repetindo-se os sintomas sempre na mesma época do ano. Clinicamente, é caracterizada por rinoconjuntivite e/ou asma brônquica. A imunoterapia alérgeno-específica é o único tratamento capaz de modificar a evolução natural da doença, porém, depende fundamentalmente da correta identificação do alérgeno responsável. Diante disso e do número de pacientes que procuram o Ambulatório de Alergia da Universidade de Fortaleza com manifestações alérgicas exacerbadas na época de floração do cajueiro, o objetivo deste estudo foi produzir um extrato protéico a partir do pólen do cajueiro e identificar os alérgenos ainda não estudados presentes neste pólen. Doze pacientes residentes em Fortaleza, Nordeste do país, foram selecionados com base na história de rinite alérgica persistente e agravamento dos sintomas no momento da floração do cajueiro. Foi selecionado outro grupo com rinite alérgica que vive na mesma região, entretanto não apresenta relação clínica com a época de floração. Além disso, foram incluídos 5 indivíduos não-atópicos e expostos ao cajueiro como grupo controle. O soro desses pacientes foi testado em Western Blot 1D e 2D (WB) e as proteínas selecionadas foram submetidas à espectrometria de massas para identificação. Os epitopos foram preditos in silico pesquisando sequências detectadas por massa contra bases de dados de epítopos já conhecidos. Foi possível identificar alguns homólogos de alérgenos de outros pólens, como isoflavona redutase (Bet v 6), beta-1,3-glucanase (Ole e 9), proteína de choque térmico 70kDa (Cor a 10), além de outras proteínas que podem representar novos alergénios, tais como aminociclase, glutamina sintetase, fosfoglucomutase, ?-1,4-glucano-proteína-sintase, factor de alongamento 2 e biotina carboxilase, entre outros. A predição de epítopos revelou a possibilidade de reatividade cruzada com outros alérgenos de pólen conhecidos, tais como Phl p 4, Mal d 1, além de outros aeroalérgenos que também apareceram. Esta é a primeira descrição da alergia ao pólen do caju mostrando a reatividade específica de IgE no soros dos pacientes. A caracterização imunológica e estrutural de novos alérgenos, além de auxiliar no diagnóstico e tratamento de alergias não descritas, oferece ferramentas para prever epítopos e produzir moléculas hipoalergênicas nesta era da medicina de precisão / Pollinosis is a seasonal allergic rhinitis that develops due to pollens sensitization. Symptoms are manifested always in the same period of the year. Clinically, it is characterized by rhinoconjunctivitis and/or asthma. Allergen-specific immunotherapy is the only available treatment that can modify the natural course of the disease, however, it relies on the correct identification of the triggering allergen. Considering this and the number of patients attending the Allergy Clinic at University of Fortaleza with exacerbation of allergic symptoms during cashew flowering period, the aim of this study was to produce a protein extract from cashew tree pollen and identify the allergens not yet studied. Twelve patients living in Fortaleza, Northeast of country, were selected based on history of persistent allergic rhinitis and aggravation of symptoms at the time of cashew tree flowering. Another group living in the same region with allergic rhinitis without clinical relation with the flowering season was selected. Also 5 non-atopic subjects exposed to cashew tree were selected as a control group. The serum of these patients was tested for 1D and 2D Western Blotting (WB) and selected proteins were submitted to mass spectrometry for identification. Epitopes were predicted by in silico search comparing detected sequences against epitope databases. It was possible to identify some homologs of allergens from other pollens such as isoflavone reductase (Bet v 6), beta-1,3-glucanase (Ole e 9), heat shock protein 70kDa (Cor a 10), besides other proteins that might represent novel allergens, such aminociclase, glutamina sintetase, phosphoglucomutase, alpha-1,4-glucan-protein-synthase, elongation factor 2 and biotin carboxylase among others. The epitope prediction revealed the possibility of cross-reactivity with other known pollen allergens such as Phl p 4, Mal d 1 and other aeroallergens also appeared. This is the first description of cashew pollen allergy showing specific IgE reactivity of patients\' sera. The immunological and structural characterization of new allergens, besides aiding the diagnosis and treatment of non-described allergies, offers tools for predicting epitopes and producing hypoallergenic molecules in this era of precision medicine

"Relação da poluição atmosférica com a citologia nasal em pacientes com rinite alérgica, residentes na cidade de São Paulo, nas diferentes estações do ano" / Relationship between environmental pollution and nasal cytology in patients with allergic rhinitis, living in São Paulo city, during the different seasons of the year

Fabiana Maia Nobre Rocha 18 November 2005 (has links)
Diferentes estudos têm demonstrado uma maior prevalência de rinite alérgica nas áreas urbanas, sugerindo um efeito decorrente da exposição à poluentes. Por esta razão, resolvemos estudar a relação da poluição atmosférica com os achados do citológico nasal em 11 pacientes com rinite alérgica nas quatro estações do ano e compará-los a 12 indivíduos normais. No verão, observamos um aumento significante de eosinófilos no grupo alérgico (p = 0,007) e um predomínio de células ciliadas no grupo controle (p = 0,021). No outono, houve um predomínio de neutrófilos no grupo controle (p = 0,027). No inverno, ocorreu um aumento de neutrófilos (p = 0,015) no grupo controle. Houve um aumento das células caliciformes (p = 0,019) no grupo alérgico. Na primavera, ocorreu um aumento dos neutrófilos (p = 0,025) no grupo controle / Different studies have demonstrated an increase in the prevalence of allergic rhinitis in urban areas, suggesting an effect resulting from exposure to pollutants. Therefore, we studied the relationship between atmospheric pollution and nasal cytological findings in 11 patients with allergic rhinitis during the four seasons of the year compared to 12 normal individuals. In summer, a significant increase in eosinophils was observed in the allergic group (p = 0.007) and there was a predominance of ciliated cells in the control group (p = 0.021). In autumn, neutrophils predominated in the control group (p = 0.027), and an increase in neutrophils (p = 0.015) was observed in winter. An increase in goblet cells (p = 0.019) was observed in the allergic group. In spring, there was an increase of neutrophils (p = 0.025) in the control group

Treatment of allergic rhinitis using a Chinese herbal formula Shi-Bi-Lin (SBL): animal study, in vitro study and clinical trial. / CUHK electronic theses & dissertations collection

January 2005 (has links)
Conclusions. SBL showed its efficacy in treating the animal model of allergic rhinitis. Its mechanisms may be related to its suppressive action on PCA reaction, the production of TXB2 and the expression of eNOS, as well as its modulation of cytokines, including IL-4, IL-6, IL-8, GM-CSF and TNF-alpha, release from mast cells. The clinical trial showed that SBL had more beneficial action on the quality of life, in comparison to the placebo, in the domains of RE and BP. Some symptoms evaluations of PAR patients, including GF, NB and SF were more markedly improved in the SBL group when compared with the placebo group. Furthermore, the use of SBL, with the study dose and treatment period, was safe. However, the accurate efficacy and mechanisms of SBL are largely unknown and need further investigation. (Abstract shortened by UMI.) / Introduction. Although great progress in treatment of allergic rhinitis have made in recent years, remarkably increasing prevalence and cost in epidemiology studies strongly suggest the difficulties in the management of allergic rhinitis. Shi-Bi-Lin (SBL) is a formula modified from the traditional Chinese herbal formula Cang-Er-Zi-San (CEZS) and a classic European formula SinupretRTM. CEZS has been used for the treatment of allergic rhinitis for several centuries in East Asia communities, and SinupretRTM has been used in treating paranasal sinusitis and rhinitis widely in Europe for decades. However, its therapeutic mechanisms remain unclear. We examined the efficacy and the possible mechanism of SBL in an animal model of allergic rhinitis and in cell culture study using Human Mast Cell Line (HMC-1) and Peripheral Blood Mononuclear Cells (PBMC). In addition, a clinical trial was conducted to examine its clinical efficacy and safety. / Results. In the animal study, SBL showed a potent effect in relieving the symptoms of nasal obstruction, sneezing and nasal scratching (P<0.05 or P<0.01), but had no convincing effect in decreasing the nasal discharge (P>0.05). In PCA test, IgG1 increased in a modest manner in the SBL-treated group when compared with the sham group (P<0.05 or P<0.01). Eosinophil infiltration and the expression of eNOS in nasal mucosa, but not iNOS, were obviously lower in the SBL treated group (P<0.05 or P<0.01) in comparison to the sham group. The levels of thromboxane B (TXB)2 in the nasal lavage fluid, but not histamine and peptide leukotrienes (p-LTs), showed significantly lower than that of the sham group (P<0.05). In vitro study showed that SBL modulated the cytokines, including interleukin (IL)-4, IL-6, IL-8, Granulocyte/Macrophage Colony-Stimulating Factor (GM-CSF) and tumor necrosis factor (TNF)-alpha, release from human mast cell line (HMC-1). However, the mRNA expressions of these cytokines were not significantly altered. As the controls, dexamethasone, desloratadine and budesonide had more potently inhibitory effects on cytokines release from HMC-1. The component herbs generally had stimulatory effects on the cytokine release from HMC-1 and variable effects on PBMC. In the clinical trial, a total of 84 patients were recruited in the clinical trial and 77 of them completed the trial. Although no significant differences of each domain between the SBL and placebo groups were detected, findings supported the efficacy of SBL were obtained. / by Zhao Yu. / "July 2005." / Advisers: C.

Untersuchungen zum allergenen Potential der luftgetragenen Algen Stichococcus bacillaris, Tetracystis aeria und Xanthonema montanum

Sommer, Nadine 14 January 2014 (has links)
Die Allergische Rhinitis als Allergie vom Typ I (Soforttyp) ist nicht nur in Deutschland und Europa weit verbreitet, sondern eine weltweit auftretende Erkrankung. Als Verursacher werden neben bereits bekannten Aeroallergenen wie Hausstaubmilben, Gräser oder Pollen auch luftgetragene Algen diskutiert, die als möglichen Mechanismus über eine T-Zell-abhängige Stimulation Antigen-bindender B-Zellen zur IgE-Produktion führen. Diese Arbeit befasst sich mit der Untersuchung des allergenen Potentials der luftgetragenen Algenspezies S. bacillaris, T. aeria und X. montanum. Dafür wurden mittels direkter und indirekter Sandwich-ELISA-Verfahren Seren von Patienten mit der Diagnose Allergische Rhinitis oder Idiopathische Rhinitis auf enthaltene IgE-Antikörper getestet, die spezifisch an festphasengebundene Algenproteine binden. Des Weiteren wurden Kompetitionstestungen zur Untersuchung der Kreuzhemmbarkeit der drei Algen sowie SDS-Gelelektrophoresen und Western Blots zur Bestimmung der Molmasse der Algenproteine und zum Nachweis der Spezifität des algenbindenden IgEs durchgeführt. Die Ergebnisse belegen, dass die getesteten Algenproteine in der Lage sind, eine entsprechende Immunantwort mit IgE-Produktion auszulösen. Diese neue Gruppe von Allergenen konnte hinsichtlich der Entstehung einer Allergie vom Soforttyp und der damit verbundenen klinischen Bedeutung bewertet werden.
