A phase IV, randomized, open label, cross-over, intervention trial to investigate the effect of the switch of protease inhibitors to raltegravir on endothelial function, chronic inflammation, immune activation and HIV replication below 50 copies/ml

1. To assess the effect of the switch from protease inhibitors to raltegravir on endothelial function. 2. To assess the effect of the intervention mentioned above on markers of endothelial function; immune activation; chronic inflammation; and, on…

Can metformin prevent endothelial ischemia and reperfusion injury?
The metformin-FMD trial.

To study the protective effect of pre-treatment with metformin on flow mediated dilation after 20 minutes ischemia and 20 minutes reperfusion. If metformin treatment indeed limits endothelial IR-injury, a second study will be performed in the same…

Effects of low-dose aspirin taken at bedtime vs. on awakening on circadian rhythm of platelet function in healthy subjects

To study the effect of 80 mg aspirin intake at bedtime compared with 80 mg aspirin intake on awakening on circadian rhythm of platelet function in healthy subjects.

Does short dipyridamole administration induce protection against ischemia-reperfusion injury?

The purpose of this project is to explore whether a short treatment with dipyridamole (2.5 days; i.e. 5 capsules) can reduce ischemia-reperfusion injury in the forearm.

Mechanisms of Albuminuria in Diabetes: Reversal of Injury to the Glycocalyx by the Ace-inhibitor Lisinopril

The primary objective of this study is to determine whether ACE inhibition results in an improvement of microvascular glycocalyx-thickness in patients with type 1 diabetes. The secondary objectives are to investigate whether this (hypothesized)…

A multicenter, randomized, double-blind, placebo-controlled, crossover trial to evaluate the effects of evolocumab added to standard lipid-lowering therapy on fasting and post fat load lipids in patients with Familial Dysbetalipoproteinemia.

To evaluate the effect of 12 weeks subcutaneous evolocumab (140 mg pre-filled pen every 2 weeks) compared to placebo on post fat load non-HDL-C levels in 30 subjects with FD, in a multicenter, randomized, placebo-controlled, double-blind, crossover…

DIStal versus COnventional RADIAL access for coronary angiography and
intervention: a randomized multicenter trial

The objective of this study is to demonstrate the superiority of Distal Transradial Access (DTRA) to Conventional Transradial Access (CTRA) regarding forearm radial artery occlusion (RAO) using the 6Fr Glidesheath Slender (GSS).

A phase 4, monocenter, prospective, randomized, placebo-controlled, double-blind, cross-over, mechanistic intervention trial to assess effect of 4-week Ertugliflozin (SGLT-2 inhibitor) therapy on renal (cortical and medullary) oxygenation as determined by BOLD-MRI and renal (cortical and medullary) oxygen consumption as determined by positron emission tomography (PET) using ¹¹C-acetate in patients with type 2 diabetes mellitus and healthy controls.

Despite multifactorial treatment approaches residual risk for the development and progression of DKD remains high and novel therapies to halt renal burden in T2DM are urgently needed. SGLT-2 inhibitors are a relatively recent additions to the…

A phase 4, monocenter, randomized, double-blind, placebo-controlled, 4-armed cross-over mechanistic intervention study to assess the renal hemodynamic effect of mono- and combination therapy with empagliflozin (SGLT-2 inhibitor) and losartan (RAS inhibitor) in metformin and/or SU-treated patients with type 2 diabetes mellitus

Investigate the effects of 7 (+-1) days of of mono- and combination therapy with the SGLT2 inhibitor empagliflozin (10 mg QD) and RAS inhibitor losartan (50 mg QD) on renal hemodynamics, (glomerular filtration rate (GFR) / effective renal plasma…
