Gliptin and GLP‐1 analog treatment improves survival and vascular inflammation/dysfunction in animals with lipopolysaccharide‐induced endotoxemia

Abstract

Dipeptidyl peptidase (DPP)-4 inhibitors are used to treat hyperglycemia by increasing the incretin glucagon-like peptide-1 (GLP-1). Previous studies showed anti-inflammatory and antiatherosclerotic effects of DPP-4 inhibitors. Here, we compared the effects of linagliptin versus sitagliptin and liraglutide on survival and vascular function in animal models of endotoxic shock by prophylactic therapy and treatment after lipopolysaccharide (LPS) injection. Gliptins were administered either orally or subcutaneously: linagliptin (5 mg/kg/day), sitagliptin (50 mg/kg/day) or liraglutide (200 µg/kg/day). Endotoxic shock was induced by LPS injection (mice 17.5-20 mg/kg i.p., rats 10 mg/kg/day). Linagliptin and liraglutide treatment or DPP-4 knockout improved the survival of endotoxemic mice, while sitagliptin was ineffective. Linagliptin, liraglutide and sitagliptin ameliorated LPS-induced hypotension and vascular dysfunction in endotoxemic rats, suppressed inflammatory parameters such as whole blood nitrosyl-iron hemoglobin (leukocyte-inducible nitric oxide synthase activity) or aortic mRNA expression of markers of inflammation as well as whole blood and aortic reactive oxygen species formation. Hemostasis (tail bleeding time, activated partial thromboplastin time) was impaired in endotoxemic rats and recovered under cotreatment with linagliptin and liraglutide. Finally, the beneficial effects of linagliptin on vascular function and inflammatory parameters in endotoxemic mice were impaired in AMP-activated kinase (alpha1) knockout mice. The improved survival of endotoxemic animals and other data shown here may warrant further clinical evaluation of these drugs in patients with septic shock beyond the potential improvement of inflammatory complications in diabetic individuals with special emphasis on the role of AMP-activated kinase (alpha1) in the DPP-4/GLP-1 cascade.

  • Treatment with linagliptin (5 mg/kg/day) and sitagliptin (50 mg/kg/day), and liraglutide (200 μg/kg/day), significantly reduced inflammatory markers such as inducible NO synthase, cyclooxygenase, and VCAM-1 via the AMPK pathway in LPS-induced endotoxemic shock in rats as a model of human sepsis.

    “Treatment with the DPP-4 inhibitors, linagliptin (5 mg/kg/day) and sitagliptin (50 mg/kg/day), and the GLP-1 analogue, liraglutide (200 μg/kg/day), significantly reduced inflammatory markers such as inducible NO synthase, cyclooxygenase, and VCAM-1 via the AMPK pathway in LPS-induced endotoxemic shock in rats as a model of human sepsis [115].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
