GDT was associated with shorter ICU stay and time to discharge and faster return of GI function compared to traditional fluid therapy. The number of adverse cardiac events was similar in the two groups.
This study tested the hypothesis that immune tolerance mediated by regulatory T (Treg) cells is protective against cystic echinococcosis (CE)-induced anaphylactic shock. BALB/c mice were inoculated with protoscoleces of Echinococcus granulosus. After 3 months, the presence of cysts in the peritoneal cavity was confirmed after which a subset of mice was sensitized using a cyst fluid suspension to induce anaphylactic shock. While IgE levels were significantly higher in both groups inoculated with E. granulosus as compared to the healthy control group (both P < 0.01), sensitized mice had higher IgE levels as compared with those with E. granulosus alone (P < 0.05). Mice inoculated with E. granulosus alone and sensitized mice both had significantly higher histamine levels as compared to the healthy controls. The proportion of CD4(+)CD25(+)Foxp3(+) Treg cells relative to CD4(+) cells was significantly higher in mice inoculated with E. granulosus alone (P < 0.0167); significantly higher interleukin-10 (IL-10) and tumor growth factor-β (TGF-β1) levels were also noted in this group (all P < 0.01). In contrast, IL-13 and IL-17A levels were significantly higher in the sensitized mice (both P < 0.05). Taken together, these data suggest that the biphasic changes in Treg cell and cytokine levels may be associated with anaphylactic shock induced by CE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
