No effective pharmacological therapy is currently available to restore microvascular barrier function in sepsis. Cholinergic mediators have been demonstrated to exert anti-inflammatory effects during inflammation. Cytidine-5-diphosphocholine (CDP-choline) is an extensively studied cholinergic drug due to its brain protective characteristics in cerebrovascular diseases. This study evaluated the effect of CDP-choline on microvascular permeability and leukocyte adhesion during endotoxemia. Methods: Macromolecular leakage, leukocyte adhesion, and venular wall shear rate were examined in mesenteric postcapillary venules of rats by using intravital microscopy (IVM). Lipopolysaccharide (LPS) (4 mg/kg/h) or equivalent volumes of saline were continuously infused following baseline IVM at 0 min. IVM was repeated after 60 and 120 min in endotoxemic and nonendotoxemic animals. CDP-choline (100 mg/kg) was applied as an i.v. bolus. Animals received either saline alone, CDP-choline alone, CDP-choline 10 min before or 30 min after LPS administration, or LPS alone. Due to nonparametric data distribution, Wilcoxon test and Dunn's multiple comparisons test were used for data analysis. Data were considered statistically significant at p < 0.05. Results: Treatment with LPS alone significantly increased microvascular permeability and leukocyte adhesion and decreased venular wall shear rate. CDP-choline significantly reduced microvascular permeability in animals treated with LPS. Leukocyte adhesion and venular wall shear rate were not affected by CDP-choline during endotoxemia. Conclusion: CDP-choline has a protective effect on microvascular barrier function during endotoxemia. Considering the excellent pharmacologic safety profile of CDP-choline, its use could be an approach for the treatment of capillary leakage in sepsis. date: 2015 publisher: BioMed Central id_scheme: DOI ppn_swb: 1653717750 own_urn: urn:nbn:de:bsz:16-heidok-194448 language: eng bibsort: SCHMIDTKARCYTIDINE5D2015 full_text_status: public publication: BMC anesthesiology volume: 15 number: 114 place_of_pub: London pagerange: 1-9 issn: 1471-2253 citation: Schmidt, Karsten ; Hernekamp, Jochen Frederick ; Dörr, Miriam ; Zivkovic, Aleksandar R. ; Brenner, Thorsten ; Walther, Andreas ; Weigand, Markus A. ; Hofer, Stefan (2015) Cytidine-5-diphosphocholine reduces microvascular permeability during experimental endotoxemia.
