Concentrações subinibitórias de antimicrobianos podem modificar os fatores de virulência da bactéria e, consequentemente, a relação micro-organismo/hospedeiro, podendo alterar a progressão da infecção. Este estudo avaliou fatores de virulência de H. pylori cultivados em ½ e ¼ da concentração inibitória mínima de amoxicilina que poderiam alterar a liberação de citocinas, indução de óxido nítrico e apoptose em macrófagos RAW 264.7 infectados. A análise proteômica foi realizada por eletroforese bidimensional e a identificação das proteínas diferencialmente expressas através da digestão por tripsina e espectrometria de massas A indução de óxido nítrico foi analisada através do reagente de Griess, as citocinas (interleucina - 1 beta, interleucina - 6, interleucina - 10, interleucina - 12, fator de necrose tumoral alfa e fator transformador de crescimento - beta) por ensaio imunoenzimático e apoptose por citometria, após 24 horas de infecção. Nossos resultados demonstraram que H. pylori previamente mantidos em sub-CIMs de amoxicilina apresentaram maior expressão de proteínas de choque térmico, enolase, argininosuccinato sintase, superóxido dismutase, ATP alfa sintase e proteína ativadora de neutrófilo, proteínas capazes de aumentar a indução de NO, IL – 1 β e IL - 12 e apoptose em relação à macrófagos infectados com H. pylori sem tratamento. Estes resultados sugerem que a amoxicilina em concentrações subinibitórias pode estimular a resposta imune no hospedeiro através da indução de alguns fator... / The infection caused by Helicobacter pylori is considered a major etiology agent in chronic gastritis, peptic ulcer, gastric carcinoma and gastric lymphomas. Sub-inhibitory concentrations of antibiotics have been shown to change virulent expression of microorganisms, which may change the progression of infection. This study assessed virulence factors of H. pylori after contact with ½ and ¼ the minimal inhibitory concentration of amoxicillin subinhibitory concentrations of amoxicillin that could modify the induction of cytokines, nitric oxide and apoptosis by infect RAW 264.7 macrophage-like cells. The proteomic analysis was realized by two dimensional electrophoresis and proteins differential expressions were characterized by tryptic digestion and mass spectroscopy. The induction of nitric oxide was assayed by Griess reagent, cytokines (interleukin – 1 beta, interleukin - 6, interleukin - 10, interleukin – 12, tumor necrosis factor alpha and transforming growth factor - beta) by Enzyme-Liked Immunoabsorbent Assay and apoptosis by annexin V - fluorescein isothiocyanate after 24 hours. Our results demonstrated that H. pylori previously maintained in sub - MICs of amoxicillin showed higher expression of virulence factors such as heat shock proteins, enolase, argininosuccinate synthetase, superoxide dismutase, ATP synthase alpha and neutrophil-activating protein inducing more oxide nitric, interleukin - 1β and interleukin – 12 and increased apoptosis than macrophages infected with H. pylori without treatment. These results suggest that amoxicillin, at sub-inhibitory concentrations, could contribute to the stimulation of immune response in the ...

Inflamação, atividade da gastrite e folículos linfóides foram mais freqüentes na mucosa de corpo e de antro gástrico com infecção. Na presença de infecção pelo H. pylori a inflamação e atividade da gastrite foram mais freqüentes e mais intensas na mucosa de antro do que na mucosa de corpo.
