Because the atherosclerosis process partly occur in the intercellular space of the vessel wall, the determination of the constitution of lipoproteins in the interstitial fluid may expand the knowledge about the atherosclerosis process and lead to a better understanding of what constitutes the increased risk of developing cardiovascular disease in patients with chronic diseases. The investigators hypothesize that the apoB-containing particles in T2D patients are more susceptible to be retained or consumed in the intercellular compartment, which in turn could be one explanation for the elevated risk of atherosclerosis. The investigators hypothesise that with the progression of chronic kidney disease this process is further increased. Patients undergoing dialysis are known to have a very high risk of cardiovascular disease. The investigators now want to study the cholesterol metabolism in interstitial fluid in subjects undergoing hemodialysis because of diabetic nephropathy and in subjects undergoing hemodialysis because of chronic kidney disease of other causes.

Inclusion Criteria:

Diabetic nephropathy, because of type 2 diabetes, undergoing hemodialysis and subjects with chronic kidney disease of other causes undergoing hemodialysis.

Exclusion Criteria:

• Active infection that increases the risk of secondary infection in the skin where the vesicles containing interstitial fluid have been emptied of interstitial fluid with a fine needle and the bladder roof is intact.
• Treatment with Warfarin due to increased risk of Calciphylaxis (calcific uremic arteriolopathy, CUA)

Diabetic nephropathy, because of type 2 diabetes, undergoing hemodialysis and subjects with chronic kidney disease of other causes undergoing hemodialysis.
