Padrões de resposta imune em pacientes com endometriose / Immune response patterns in patients with endometriosis

Podgaec, Sérgio 12 September 2006 (has links)
Objetivo: O objetivo deste estudo foi analisar a relação e a predominância dos padrões de resposta imune Th1 e Th2 em pacientes com endometriose. Pacientes e Métodos: Entre Fevereiro de 2004 e Abril de 2005 foram avaliadas 98 pacientes divididas em dois grupos de acordo com a presença (Grupo A) ou ausência de endometriose (Grupo B), confirmada histologicamente. Foram coletados sangue periférico e fluido peritoneal de todas as pacientes para a dosagem de interleucinas (IL) 2, 4 e 10, fator de necrose tumoral-alfa (TNF-alfa) e interferon-gama (IFN-gama) por citometria de fluxo. Além da presença da endometriose, foram analisadas a fase do ciclo menstrual, o quadro clinico, o estadiamento, o local de acometimento e a classificação histológica da moléstia. Resultados: Observou-se elevação estatisticamente significante nas concentrações de IFN-gama (mediana de 1,5pg/ml no Grupo A e de 0,4pg/ml no Grupo B, p=0,03) e de IL-10 (mediana de 38,6pg/ml no Grupo A e de 15,7pg/ml no Grupo B, p=0,03) do fluido peritoneal das pacientes com endometriose em relação àquelas sem a doença. As pacientes com endometriose apresentaram alteração estatisticamente significativa na relação das concentrações de IL-4/IFN-gama (p<0,001), IL-4/IL-2 (p=0,006), IL-10/IFN-gama (p < 0,001) e IL-10/IL-2 (p<0,001) do fluido peritoneal, com concentrações mais elevadas da IL-4 e da IL-10, o que reflete o predomínio da resposta Th2 sobre a Th1. Conclusão: Os resultados obtidos permitem concluir que, neste estudo, observou-se elevação de citocinas relativas à resposta imune Th2, denotando haver um predomínio deste padrão de resposta em pacientes com endometriose. / Objective: The objective of this study was to analyze the relation and the predominance of the immune response patterns Th1 and Th2 in patients with endometriosis. Patients and Methods: Between February 2004 and April 2005, 98 patients were evaluated and divided into two groups, according to the presence (Group A) or absence of endometriosis (Group B), confirmed by histology. Peripheral blood and peritoneal fluid were collected from all patients to obtain the concentrations of interleukines (IL) 2, 4 and 10, tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) using flow cytometry. Besides the presence of endometriosis, we analyzed phase of menstrual cycle, clinical complaints, classification, site and histological differentiation of the disease. Results: We observed higher concentrations of IFN-gamma (median of 1.5pg/ml in Group A and 0.4pg/ml in Group B, p = 0.03) and IL-10 (median of 38.6pg/ml in Group A and 15.7pg/ml in Group B, p = 0.03) in peritoneal fluid of patients with endometriosis in relation to those without the disease. Patients with endometriosis presented a significant alteration in IL-4/IFN-gamma (p < 0.001), IL-4/IL-2 (p = 0.006), IL-10/IFN-gamma (p < 0.001) and IL-10/IL-2 (p<0.001) ratio concentrations of peritoneal fluid, with IL-4 and IL-10 predominance, reflecting a Th2 response predominance over the Th1. Conclusion: The results allow concluding that, in this study, it was observed a cytokine elevation related to Th2 immune response, indicating a predominance of this pattern of response in patients with endometriosis.

Muitos fatores podem predispor ao aparecimento de úlceras e acúmulo de gases no abomaso, incluindo alimentos grosseiros, estresse ambiental, deficiências de vitaminas e minerais e infecções bacterianas. Essas úlceras podem ser subclínicas, sendo descobertas nas necropsias ou após o abate do animal, ou levarem à redução da motilidade do órgão, prejudicando o fluxo do seu conteúdo e causando transtornos digestivos graves e até ao aparecimento de síndromes semelhantes à indigestão vagal. Existem informações a respeito da resposta do sistema imune na maior parte das mucosas do trato gastrintestinal de não-ruminantes e ruminantes, porém são raras a respeito do abomaso. Os objetivos desse estudo foram detectar os níveis de citocinas (IL-17A, IFN-γ, TNF-α, IL-10, IL-6, IL-4, IL-2) no conteúdo abomasal em bovinos de corte, determinar o perfil Th1 ou Th2 dessas citocinas em animais com úlceras de grau 1 e 2 na região cárdica abomasal e comparar esses valores com os níveis de citocinas de animais sem úlceras (controle), em amostras colhidas em abatedouro, para auxiliar na compreensão da fisiopatologia do processo inflamatório local. A avaliação macroscópica e a classificação das úlceras foi realizada por meio de exames visual e histológico em amostras de tecidos da parede da região cárdica abomasal ulcerada. Os níveis de citocinas produzidas do líquido abomasal dos animais com ou sem úlceras foram avaliados por citometria de fluxo (método Cytometric Bead Array). As citocinas citadas foram detectadas no líquido do abomaso dos bovinos. Não houve diferença na liberação das citocinas entre os grupos com úlceras e o grupo sem úlcera, indicando um equilíbrio entre perfis Th1 e Th2 da resposta inflamatória. / Erosions and ulcers are common findings in the abomasum and cause economic concern in several livestock production systems. Many factors may predispose to ulcers and bloat in the abomasum, including roughage, environmental stress, deficiencies of vitamins and minerals and bacterial infections. These ulcers may be subclinical and are found during necropsy or after slaughter, or lead to reduction of abomasal motility, hindering the flow of your content and causing serious digestive disorders and even the appearance of syndromes similar to vagal indigestion. There are some studies evaluating the immune system response in most of the mucous membranes of the gastrointestinal tract of non-ruminants and ruminants, but rarely related to the abomasum. The aims of this study were to investigate the levels of cytokines (IL-17A, IFN-γ, TNF-α, IL-10, IL-6, IL-4, IL-2) in the abomasal fluid of beef cattle, to determine the Th1 or Th2 profile of these cytokines in animals with types 1 or 2 ulcers located in the abomasal cardic region and to compare these levels with those of animals without ulcers (controls), in samples collected in an abbatoir, to help to the understand the pathophysiology of the local inflammatory process. Ulcers from the abomasal cardic region were macroscopicaly evaluated, then classified by histology. Cytokine levels in the abomasal fluid from animals with or without ulcers were evaluated by flow cytometry (Cytometric Bead Array). Cytokines were detected in the abomasum fluid of cattle. There was no difference in the release of cytokines between groups, indicating a balance between Th1 and Th2 profiles of the inflammatory response.
