Insights in proximal and distal tubular iron reabsorption by studies on urinary iron excretion in human health and disease

We aim to gain insights in proximal and distal tubular reabsorption of iron, transferrin, NTBI and labile plasma iron (LPI). To this purpose, we will study urinary iron, transferrin, NTBI and LPI concentrations relative to urinary creatinine…

ADOLESCE-NT: More rapid deterioration of renal function after renal transplantation in adolescence: effect of the endocrine system on immunological and pharmacokinetic factors

Answering the question if there are any associations between hormonal status in adolescence on the one hand, and immunological reactivity and pharmacodynamics on the other hand; and if such associations can explain the more rapid deterioration of…

A prospective Randomized Controlled Trial to Evaluate the Primary Prevention of sudden cardiac death using implantable cardioverter defibrillators in dialysis patients.

The main objective of this study is to assess whether ICD therapy in dialysis patients reduces sudden (arrhythmogenic) cardiac death. The first secondary end point is to compare total mortality death between the two groups. An other is to evaluate…
