I3LTE4: Intensive Insulin Therapy and Production of LTE4 in Patients With Diabetes
Effect of an Intensive Insulin Therapy on the Production of LTE4 in Patients With Diabetes
研究概览
详细说明
Our group has recently reported the results of a preliminary cross-sectional study, which demonstrated that the urinary LTE4 excretion is increased in patients with type 1 diabetes. With regard to recent human genetic studies showing that polymorphisms in the 5-lipoxygenase (5-LO) promoter and FLAP haplotypes is linked to cardiovascular disease susceptibility our data suggested the potential interest of LTE4 as a non-invasive biomarker of cardiovascular risk. In diabetes mellitus, further studies are required to evaluate the 5-LO pathway after improvement of glucose control and concomitantly with established inflammatory cardiovascular biomarkers.
The secondary objectives are:
Before and after 3-month intensive insulin therapy- Relationship between a marker of platelet activation (urinary 11-dehydro-thromboxan B2 :11-dehydroTXB2) and urinary LTE4- Relationship between inflammatory plasma markers of cardiovascular risk (hs-CRP and fibrinogen) and urinary LTE4- Relationship between a plasma marker of endothelial dysfunction (sICAM-1) and urinary LTE4- Changes in LTE4 according to patient subgroups (patients with type 1 and type 2 diabetes mellitus)
