There are about 13332 clinical studies being (or have been) conducted in Netherlands. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Nowadays it has become evident that a chronic systemic inflammation is present in patients suffering from chronic obstructive pulmonary disease (COPD). The role of the nuclear enzyme poly(adenosine diphosphate-ribose)polymerase (PARP) as a key mediator within these systemic inflammatory processes as well as in COPD associated exercise intolerance and muscle weakness could recently been identified. The attenuating effect of dietary ingredients with PARP inhibiting activity on systemic inflammation was supported by data from in vitro and in vivo studies, from other groups as well as from our own lab. We identified several caffeine metabolites as potent inhibitors of the most abundant PARP-isoform PARP-1 in-vitro, in animal models as well as in ex-vivo experiments with whole blood from COPD patients. However, clinical data with respect to their anti-inflammatory effects in COPD patients are currently not available for none of these substances. Therefore, the current clinical pilot study is intended to establish for the first time clinical data (proof of principle) on the anti-inflammatory potential of caffeine metabolites.
The purpose of this study is to determine the effect of AZD1236 in patients with cystic fibrosis (CF) on inflammatory biomarkers in induced sputum, after a treatment period of 4 weeks.
The stress response as induced by myocardial cellular damage during cardiac surgery may lead to myocardial stunning and apoptosis, and could therefore impair postoperative patient recovery. Surgical trauma typically induces the liberation of cytokines. Some of these cytokines are strongly associated with the initiation of intracellular proapoptotic pathways through activation of tyrosine kinases and integrins. The latter are known for their deteriorating effects on cardiac function and are strongly involved in cardiac remodeling. Dexamethasone is typically administered prior to cardiac surgery in order to especially reduce the release of proinflammatory cytokines. It has however never been investigated whether this additionally reduces proapoptotic signaling in the human heart, thereby eliminating risk factors for the induction of cardiac dysfunction. In the present study, the investigators therefore aim to investigate whether dexamethasone inhibits proapoptotic pathways in patients undergoing cardiac surgery. Furthermore, the investigators would like to elucidate whether this proposed effect of dexamethasone is related to the reduction of the stress response in the heart or indirectly by suppression of cytokine release. For this purpose the investigators will obtain cardiac biopsies and plasma from patients, who are randomly assigned to placebo or dexamethasone treatment and undergo on and off-pump coronary artery bypass grafting (CABG) surgery.
The purpose of this study is to determine if quinidine therapy (not guided by the results of electrophysiologic studies) will reduce the long-term risk of arrhythmic events in asymptomatic Brugada Syndrome.
The study is using a new breast lift system to complement a breast-lift operation. In general there will be recurrence of breast-ptosis after a correcting operation. With this device we want to minimize this recurrence and provide an "internal bra".
Exogenously administered testosterone will override the normal negative feedback of endogenous testosterone on the hypothalamus and pituitary. Constantly, relatively high and constant testosterone levels will cause a drop in FSH and LH production by the pituitary. Since FSH and LH are signalling hormones to the testes, endogenous testosterone production and spermatogenesis will be down-regulated. It is expected that intranasal dosing in the morning will mimic the normal physiological pattern of testosterone production thereby avoiding negative side-effects on spermatogenesis. Trans-dermal gels give testosterone levels more or less constant over the day and will very likely have inhibitory effects on spermatogenesis. The main objective of this study is to show that twice daily intranasal dosing does not have, or has a smaller inhibitory effect on spermatogenesis in comparison to transdermal testosterone gels.
This study examines the muscle protein signalling response after resistance and endurance exercise. We hypothesize that the signalling response after endurance and resistance exercise will be partly similar.
In this study, a combination of two T-cell directed antibodies both conjugated to a cell-killing toxin will be evaluated. Previous in vitro studies have demonstrated that this so-called immunotoxin-combination (IT-combination) acts synergistically in eliminating T cells. In a subsequent clinical pilot-study, the IT-combination has generated encouraging results when applied as third line therapy. Extensive biological and clinical responses could be noted in the absence of severe acute toxicities. Building on this experience, the current study aims at evaluating the characteristics of the IT-combination when administered in an earlier phase of the disease, i.e. as second line instead of as third line therapy.
The purpose of this study is to assess whether baseline sympathetic innervation in patients with chronic heart failure (CHF) is predictive for response to cardiac resynchronization therapy (CRT). And to assess whether response to CRT coincides with restoration of regional sympathetic innervation.
The purpose of this study is to establish the tolerability of treatment with human lactoferrin 1-11 peptide (hLF1-11) administered intravenously as a single dose given for 10 consecutive days, to patients with bacteremia due to staphylococcus epidermidis.
