Contrast-induced nephropathy (CIN) is a side-effect of intravascular administration of iodinated contrast material. It is defined as an absolute (>44μmol/l) or relative (>25%) increase in serum creatinine from baseline values within 48-72 hours of iodinated contrast material administration, and usually resolves within two weeks. In some cases CIN has been associated with persistent renal failure, increased risk of dialysis, and mortality. It is not clear however, whether CIN is causally related to this increased risk or whether risk of morbidity and mortality is inherent in those at risk of CIN. CIN itself is asymptomatic and no treatment for CIN exists. Therefore, the focus lies on its prevention. Prevention guidelines have been drawn up in most countries and been implemented in most radiological departments. In the Netherlands, currently two guidelines for the prevention of CIN coexist, issued by CBO (Centraal BegeleidingsOrgaan) and VMS (Veiligheids Management Systeem). The prevention guidelines aim to increase patient safety by identifying patients that may be at risk of CIN (mostly patients with chronic renal insufficiency), and subsequently administering prophylactic intravenous hydration to the so identified patients, in order to prevent CIN (intravenous normal saline 4-12 hours before and 4-12 hours after exposure to iodinated contrast material). Needless to say, the introduction of these guidelines has had a great impact on patient- and health care burden. In the Netherlands alone it is estimated that yearly 100.000 to 150.000 patients receive the prophylactic treatment, incurring a total cost of over 50 million Euro. Considering the steady yearly increase of contrast procedures and the ageing population, it is evident that, in future, these numbers shall only increase further. The prophylactic treatment prescribed by the guidelines is based on a consensus of the opinion of experts in general agreement that the treatment is beneficial. However, the effectiveness of prophylactic hydration has never been adequately evaluated. Sufficiently large randomised trials comparing prophylactic intravenous hydration with a proper control group receiving no prophylactic treatment are not available, and baseline CIN incidences in untreated populations are unknown. Thus, it is not clear whether prophylactic hydration achieves its aim to prevent CIN. In order to be able to take effective measures to the benefit of patient safety, it is important to distinguish between the mechanisms underlying CIN and the ensuing increased risk of morbidity and mortality: whether it be biological variation of serum creatinine, renal damage, or cholesterol embolism; whether any causality exists between these and iodinated contrast material; and whether prophylactic intravenous hydration can prevent these from occurring without incurring more risks than it removes. These, in short, are the aims of the AMACING study.
Cryotherapy has a long history of safe use in various medical procedures. RejuvenAir System radial spray cryotherapy is a novel procedure being developed as a treatment for conditions associated with abnormal bronchial function, such as chronic bronchitis. The development of appropriate reliable equipment, definition of therapeutic parameters, and an understanding of the tissue effects of treatment have been established through animal studies. This clinical study is being undertaken to assess the feasibility and safety of the application of a radial metered dose spray cryotherapy in the human airway and to evaluate the treatment depth in human airways. The study design is prospective, open label, single arm multi-center study that will consist of up to 15 subjects at up to 3 enrolling sites in Ireland, UK and The Netherlands RejuvenAir System treatment will be performed during preoperative bronchoscopy 0 to 60 days prior to prescheduled lung resection in Subjects requiring lobectomy or pneumonectomy for removal of peripheral tumors. Treatment will be limited to areas of the bronchi within the lobe that will be removed, distal to the anticipated margin of resection. Treatment should be at least 1 cm from the bronchial resection margins and away from the tumor bed. Treated airways will be inspected via bronchoscopy at the time of thoracotomy, and examined histologically following surgical resection. Subject participation will be from 1 to 60 days and enrollment is anticipated to take 4-5 months.Total study duration is expected to last approximately 10 months.
Although the clinical outcome in patients with Invasive Aspergillosis (IA) is largely dependent on early initiation of effective treatment with antifungal drugs, diagnosing IA is still a critical problem. Symptoms are non-specific and available diagnostic tools are either invasive or have low sensitivity and specificity. This often results in a diagnostic delay, with patients developing more extensive disease. Furthermore, as long as IA is present, oncological follow-up treatment is not feasible. Inaccuracy in diagnosing IA can cause serious treatment delay and increased mortality. However, an empirical strategy with prophylactic anti-mould therapy is not feasible considering both possible side effects and costs. In order to safely continue the use of a pre-empirical strategy, improved (non-invasive) diagnostic tools are desirable. In a pilot study de Heer et al. showed that it is possible to discriminate between patients with IA and their neutropenic controls by exhaled breath analysis using an electronic nose (eNose). In this study the investigators aim to test whether an eNose could be useful as a diagnostic tool in a prospective setting. The gold standard in exhaled breath analysis is Gas Chromatography - Mass Spectrometry (GC-MS). This technique enables identification of volatile organic compounds (VOCs) in breath of patients. It is possible that there are Aspergillus specific VOCs in the breath of patients with IA. The composition of the lung microbiome seems to be an important factor in both health and disease. It is likely that the microbiome of the lung changes in prolonged neutropenia, therefore possibly creating a niche for molds and yeasts. Comparing the microbiome of patients with prolonged neutropenia who develop IA with those who do not, can learn us more about the pathogenesis of this disease. This knowledge could be used to investigate new treatment options for Invasive Aspergillosis. Hypothesis The investigators hypothesize that airway microbial (viral, bacterial) presence and exhaled molecular profiles as obtained from patients with prolonged neutropenia due to treatment of hematological malignancies, are different between patients who develop IA and patients who do not.
The aim of this study is to detail the (mechanisms underlying the) actions of the DPP-4 inhibitor linagliptin on the renal system in patients with type 2 diabetes mellitus.
This is a multi-centered, randomized, placebo-controlled, double-blind, parallel group, trial evaluating 2 doses of mepolizumab against placebo given every 4 weeks through subcutaneous (SC) injection. In severe COPD subjects, sputum eosinophils levels are elevated to similar levels as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD subjects would translate into a reduction of COPD exacerbations. The study will evaluate the efficacy and safety of mepolizumab, in subjects who are at or above the baseline blood eosinophil count of at least 150 cells/microliters who exacerbate despite regular use of maximal tolerated therapy, appropriate for severe COPD subjects, in the 12 months prior to study start. In total, 660 subjects will be randomized in 1:1:1 ratio to receive mepolizumab 300 mg, mepolizumab 100mg, or placebo administered SC. The total duration of subject participation will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.
The purpose of this study is to find out whether Nivolumab will significantly improve overall survival as compared to therapy of investigator's choice in patients with recurrent or metastatic head and neck carcinoma.
Rationale: The construction of esophageal anastomoses is associated with considerable risk at postoperative anastomotic leakage. Application of TachoSil®, a tissue sealant with human fibrinogen and thrombin, can improve strength of the esophageal anastomosis and potentially prevent anastomotic leakage. Objective: Evaluation of feasibility and safety of TachoSil® application on esophageal anastomoses. Study design: Non-randomized, non-blinded, single-center intervention study. Study population: Patients, 18-80 years old, undergoing an elective total gastrectomy with an esophago-jejunostomy or esophagectomy with a planned esophagogastric anastomosis will be enrolled. A total number of 15 patients will be included in the study. Intervention: Gastric or esophageal resection will be executed according to the common procedures used in the UMC Utrecht. After construction of the esophageal anastomosis, all enrolled participants will receive a TachoSil® patch, which will be applied on the esophageal anastomosis intra-operatively. Hence, TachoSil® is used as an add-on therapy. TachoSil® will be degraded enzymatically in a period of approximately 24 weeks after application. Main study parameters/endpoints: The primary endpoint is feasibility, which is assessed by evaluation of adherence of the patch. A time-action analysis of the application of the Tachosil patch will be performed. Nature and extent of the burden associated with participation: The burden for the patient is minimal. The total surgical procedure will be prolonged with 10-15 minutes. Postoperative care and outpatient visits do not differ from regular protocol. TachoSil® is approved and registered for supportive treatment in surgery for improvement of haemostasis and to promote tissue sealing by the European Commission.
