Role of different phosphate binders on absorption of vitamin K, metabolism of matrix *-carboxy-glutamaat (Gla) proteïne (MGP).

This research will have as aim to look at progression or decrease of vascular calcification in dialysis population with use of different phosphate binders. There is a possibility that differect phosphate binders bind vitamin K in a different way in…

Utility of BOLD MRI as diagnostic tool in renal artery stenosis in patients with hypertension and chronic kidney disease

Is the BOLD MRI able to show the difference in the level of oxygenation as a mesurement of ischemia between a in a healthy kidney (<30% renal artery stenosis) and a kidney with more than 70% artery stenosis?

Immune monitoring to characterize T-cell responses of kidney transplant patients during co-stimulation blockade by belatacept

Here, we postulate that the balance between the effect of belatacept on regulatory T-cell function and the relative insensitivity of memory T-cells for belatacept leads to donor-specific alloreactivity. We plan to study the peripheral CD28-dependent…

SYMPATHY: Renal sympathetic denervation as a new treatment for therapy resistant hypertension.

The primary objective is to assess whether RD added to usual care compared to usual care alone reduces BP (24-h or average day-time SBP as determined with the use of ambulatory BP monitoring (ABPM)) in subjects with an average mean day-time SBP of…

The efficacy of an antigenic marker lesion for the therapeutic effect in patients with multiple, Ta/T1, G1/G2, non-muscle invasive bladder cancer (NMIBC) treated with TUR followed by IL-2 instillation

We like to demonstrate that treatment of non-muscle invasive bladder carcinoma with incomplete TUR and IL-2 is therapeutically more effective than treatment with complete TUR and IL-2.

Urolastic® versus Bulkamid® in treatment of female stress incontinence: randomized controlled trial.

Subjective cure of urinary stress incontinence at 12 months after intervention and comparison of a new bulking agent Urolastic ® with Bulkamid® in the treatment of stress urinary incontinence. Our hypothesis: based on our study and literature…

A 24 month, multicenter, randomized, open-label safety and efficacy study of concentration-controlled everolimus with reduced calcineurin inhibitor vs mycophenolate with standard calcineurin inhibitor in de novo renal transplantation- Advancing renal TRANSplant eFficacy and safety Outcomes with an eveRolimus-based regiMen (TRANSFORM)

Primary: to evaluate the effect of everolimus with reduced exposure CNI versus MPA with standard exposure CNI on the binary composite of treated biopsy-proven acute rejection (tBPAR) or eGFR < 50mL/min/1.73m2 at Month 12 post-transplantation.…

Reducing costs of surveillance of patients with non-muscle invasive bladder cancer.

1) To prove that it is possible to safely reduce the number of invasive cystoscopies during follow-up (FUP) of patients with NMIBC with a low/intermediate risk of recurrence or progression. 2) To prove that addition of urine tests to the follow-up…

A Maastricht Contrast-Induiced-Nehropathy Guideline study (AMACING): prevention guidelines - appropriate and cost effective?

The AMACING study aims to evaluate the (cost) effectiveness of guideline prescribed intravenous prophylactic hydration in the prevention of: CIN, decrease in renal function, renal damage, 30-day morbidity and 30-day mortality; taking into account…

Single Blind Randomized Phase III Trial to Investigate the Benefit of a Focal Lesion Ablative Microboost in Prostate Cancer

- Primary study objective: To demonstrate the superiority of the ablative microboost dose schedule regarding 5-year biochemical no evidence of disease rate compared to the current standard of care.- Secondary study objectives: Establish and compare…

A multicentre randomised controlled trial to compare the efficacy of ex-vivo oxygenated hypothermic machine perfusion with non-oxygenated hypothermic machine perfusion of kidneys from donors older than 50 years of age and donated after circulatory death.

To compare the effect of oxygenated versus non-oxygenated hypothermic machine perfusion of grafts of DCD category III (awaiting circulatory death - controlled), kidneys aged 50 years or older on kidney graft function.

SEQUENTIAL THERAPY WITH TACROLIMUS AND RITUXIMAB IN PRIMARY MEMBRANOUS NEPHROPATHY

PRINCIPAL OBJECTIVE To evaluate whether sequential therapy with tacrolimus for 9 months (6 months of full therapy and 3 months of tapering doses) followed by a dose of RTX leads to a greater increase in the proportion of primary MN patients with…

A Phase 3, Randomized, Open-Label, Active-Controlled Study to Evaluate the Efficacy and Safety of roxadustat in the Treatment of Anemia in Chronic Kidney Disease Patients Not on Dialysis
