Efeitos da dieta hiperlipídica sobre o tecido hepático na esquistossomose mansônica experimental

Schistosomiasis remains a serious public health issue and still belongs to the list of neglected diseases in Brazil with a significant socio-economic impact. It is estimated that 207 million people are infected, 500 thousand die annually and 120 million are asymptomatic. The characteristic pathological process is the presence of hepatic granuloma characterized as the body's defense reaction to egg insulation and protection against the release of their antigens. The aim of the study was to evaluate the influence of high fat diet on liver tissue in an experimental model of schistosomiasis mansoni using 35 female mice divided into 4 groups: fat diet and Infected - H + I (n = 9), Infected - I ( n = 7), high fat diet - H (n = 9) and control - C (n = 10). Tissue specimens were fixed and made histological and morphometric studies as numbers, volumes and granulomas developments, as well as quantification of collagen density. The prevailing characterization of granulomatous phase (FG) was observed in group I than H + I, along with a better collagen formation in the H + I group compared to the other groups. During the study we observed the absence of steatosis in H + I group. The study showed that the presence of fat diet alters some rearrangements in granulomatous formation, leading to the need for more intense observations about the theme.
