Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A number of arguments suggest that the deterioration in high density lipoproteins (HDL) functioning may worsen with the development of nephropathy during type 1 diabetes (T1D).

The objective of this study will be to investigate to what extent nephropathy in T1D patients in the microalbuminuria and macroalbuminuria stages, compared to T1D patients without nephropathy, is associated with an alteration in HDL functionality and changes in HDL size and composition (lipids with detailed study of phosphates and sphingolipids, main lipoproteins, inflammatory markers).
