Start date: July 15, 2017

NCT ID: NCT03187912 Recruiting - Keratoconus Clinical Trials

Accelerated Corneal Cross-linking With Different Riboflavin Solutions

Start date: September 19, 2016
Phase: Phase 3
Study type: Interventional

Following the Bunsen-Roscoe law, accelerated cross-linking protocols with higher irradiation intensities and shorter irradiation times have been introduced. In addition, new riboflavin solutions with HPMC (hydroxylpropyl methylcellulose) instead of dextran found its way into CXL-treatment. The aim of this trial is to evaluate clinical outcomes in an accelerated corneal collagen cross-linking protocol with different riboflavin solutions.

NCT ID: NCT03184610 Completed - Keratoconus Clinical Trials

Distinguishing Healthy and Keratoconic Eyes Using Ultrahigh-Resolution OCT

Start date: December 2014
Phase: N/A
Study type: Observational

The OCT used in this trial offers the advantage of both a non-contact method and a very high axial resolution. Determined parameters with the highest potential of diagnostic discrimination between eyes with Keratoconus and healthy eyes are investigated. Aim of this trial is to investigate differences of specific parameters of epithelium thickness maps at healthy eyes and eyes with Keratoconus.

NCT ID: NCT03182699 Not yet recruiting - Clinical trials for Secondary Hyperparathyroidism

Effect of Etelcalcetide on Cardiac Hypertrophy in Hemodialysis Patients

Start date: September 1, 2017
Phase: Phase 4
Study type: Interventional

Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").

NCT ID: NCT03180996 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Global Fenestrated Anaconda Clinical sTudy

Global FACT
Start date: July 2017
Phase: N/A
Study type: Observational

This study is a prospective non-interventional, multi-centre study of the Vascutek Fenestrated Anaconda™ system, and is essentially a post-market study. The Vascutek Fenestrated Anaconda™ system is a custom made device used for the treatment of Abdominal Aortic Aneurysm.

NCT ID: NCT03180931 Active, not recruiting - Coronary Thrombosis Clinical Trials

Independent OCT Registry on Very Late Bioresorbable Scaffold Thrombosis

Start date: December 2, 2016
Phase: N/A
Study type: Observational [Patient Registry]

Bioresorbable vascular scaffold (BVS, ABSORB BVS1.1, Abbott Vascular) has been approved (CE mark) and is used in daily clinical practice. While recent randomized controlled trials comparing BVS versus metallic drug-eluting stent showed higher risk of definite or probable device thrombosis after BVS implantation, the causes underlying thrombotic events occurring beyond one year after scaffold implantation remain unclear and require investigation in an independent manner. The INVEST registry is a world-wide, multi-center, observational, retrospective, investigator-initiated registry, which will include any patients who suffered from very late (>1 year) scaffold thrombosis, underwent optical coherence tomography (OCT) at the time of thrombosis and provided informed consent for the further use of their health related data for this registry.

NCT ID: NCT03177720 Recruiting - Pneumonia Clinical Trials

Evaluation of Innovative Tools in Development of Antibiotics

Start date: May 29, 2016
Phase: Phase 1
Study type: Interventional

The investigators will determine the difference of pharmacokinetics of ciprofloxacin and imipenem between healthy volunteers and intensive care patients suffering from pneumonia in plasma and at the target site - lung - using bronchoalveolar lavage. As additional aspect the feasibility of combining microdosing of C14 ciprofloxacin with microdialysis, saliva sampling and bronchoalveolar lavage is studied by comparing pharmacokinetics of microdose and macrodose.

NCT ID: NCT03172468 Not yet recruiting - Cardiac Arrest Clinical Trials

Definition of Hemodynamic Thresholds in Out-of-Hospital Cardiac Arrest

Start date: May 2017
Phase: N/A
Study type: Observational

This study seeks to evaluate, whether patients suffering from cardiac arrest, that can be successfully resuscitated, can be differentiated from those, that cannot be resuscitated, using arterial blood pressure values.

NCT ID: NCT03171909 Recruiting - Clinical trials for Twin Pregnancy With Antenatal Problem

Austrian Registry on the Outcome of Monochorionic Pregnancies

Start date: May 1, 2017
Phase: N/A
Study type: Observational [Patient Registry]

About one third of twin pregnancies are resulting from a single fertilized oocyte. Two third of these monozygotic twins share a common placenta and are therefore called monochorionic. Due to placental sharing and the ever-present inter-fetal vascular connections, specific complications may arise and lead to an increased risk of intrauterine death and long-term neurodevelopmental impairment. Specific complications include twin-to-twin transfusion syndrome (TTTS), twin-anemia-polycythemia sequence (TAPS), selective intrauterine growth restriction (sIUGR) and discordant major anomalies, occurring in about 10%, 5%, 20% and 6% of monochorionic diamniotic twins. Prenatal interventions may improve perinatal and long-term outcome of affected fetuses. However, general knowledge about early diagnosis of monochorionic twins and their specific complications is still limited in a significant number of practitioners in Austria and systematic analysis of pregnancy outcomes are not conducted. In this prospective multicenter registry study, the investigators aim to include all monochorionic pregnancies in Austria. Main outcome parameter is the occurrence of complications. Secondary outcomes are gestational age at occurrence of complications, gestational age delivery and neonatal outcome. The investigators also strive for long-term outcome, especially of infants following complicated pregnancies or preterm birth.

NCT ID: NCT03171467 Recruiting - Clinical trials for Laparoscopic Cholecystectomy

Salpingectomy at the Time of Elective Laparoscopic Cholecystectomy (SaLCHE)

Start date: August 1, 2016
Phase: N/A
Study type: Interventional

Prophylactic salpingectomy (also called opportunistic, risk-reducing or incidental salpingectomy) has been advocated at the time of gynecologic surgery to reduce the risk of serous ovarian cancer. This study explores the acceptability and feasibility of opportunistic salpingectomy at the time of elective laparoscopic cholecystectomy (LCHE).
