NCT ID: NCT03104036 Recruiting - Ulcerative Colitis Clinical Trials

Faecal Bacteriotherapy for Ulcerative Colitis

Start date: April 2017
Phase: Phase 2
Study type: Interventional

The etiopathogenesis of ulcerative colitis (UC) is not fully understood. One of the theories of UC pathogenesis represents a pathological response of mucosal immunity to intestinal microbiota. Potential therapeutic procedure how to affect this fact is the faecal microbiota transplantation (FMT). Review of the literature on FMT suggests great potential as the treatment for UC, but two prospective controlled study that has been published yet are inconsistent. The first objective of the project is to compare the administration of FMT enema with mesalazine enema for inducing remission in patients with active left-sided UC in the form of a prospective, randomized, controlled study. The second objective is to observe changes in the intestinal microbiota during and after FMT focusing on bacterial DNA sequencing to identify the bacterial species which are responsible for the effect of the FMT.

NCT ID: NCT03093311 Recruiting - Clinical trials for Cognitive Dysfunction

Near Infrared Spectroscopy for Detection of Cerebral Desaturation After Positioning for Neurosurgical Procedures

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

The occurrence of postoperative cognitive dysfunction (POCD) might be related to intraoperative cerebral desaturation. Positioning for neurosurgical procedures are associated with head rotation, elevation, flexion or extention that may affect blood brain inflow and outflow. Anatomical variations of Willis circle could affect the cerebral blood flow in extreme head position with the development of cerebral ischemia or functional changes of brain. Investigators suppose that detection of cerebral tissue desaturation and its prompt correction could modify the occurence of POCD after these procedures.

NCT ID: NCT03090763 Recruiting - Aortic Aneurysm Clinical Trials

Role of Circulating MicroRNAs in Pathogenesis of Aneurysms of the Abdominal and Thoracic Aorta - Study "Micro AAA"

Start date: November 1, 2016
Phase: N/A
Study type: Observational

The objective of this study is to establish whether patients with aortic aneurysm, compared to general population, have higher levels of selected miRNAs and whether there is significant association between the level of miRNA in circulating blood and the size of the aortic aneurysm or the risk of its rupture.

NCT ID: NCT03077048 Recruiting - Clinical trials for Renal Insufficiency, Chronic

Short-term Metabolic Effects of Ketosteril® Supplemented Low Protein Diet in Pre-dialysis Chronic Kidney Disease (CKD) Patients

Start date: March 30, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

Supplementation of ketoanalogues of essential amino acids improves the protein quality of protein restricted diets without burdening the kidneys. The ketoanalogues are transaminated by aminotransferases to the corresponding amino acids by incorporating nitrogen from amino groups derived from endogenous amino acid degradation. Therefore, less nitrogen needs to be excreted and the kidney's workload is reduced. The purpose of the trial is to investigate the impact of Ketosteril® supplementation on A) nutritional safety and tolerance of a low protein diet (LPD) (0.6 g protein/kg bodyweight (BW)/day)and B) net protein synthesis in pre-dialysis CKD patients. Changes of urea in serum and urine will be assessed under controlled metabolic balance conditions in non-dialysed CKD patients consuming a LPD supplemented with Ketosteril® at 1 tablet/5 kg body weight/day compared to the same, isonitrogenous and isocaloric diet without Ketosteril®. Changes in protein synthesis and degradation at the defined protein intake with or without Ketosteril® supplementation will be investigated - based on nitrogen balance, normalized protein catabolic rates as well as blood levels of defined proteins as surrogate markers for net protein synthesis and anabolic signaling.

NCT ID: NCT03072524 Recruiting - Stroke Clinical Trials

The Prehospital Selection of Acute Stroke Patients

Start date: March 1, 2016
Phase: N/A
Study type: Observational

The aim of this study is to develop and validate a simple prehospital stroke scale, which would predict the presence of large vessel occlusion (LVO) in patients with acute stroke. This study prospectively evaluates the predictive value of a new simple pre-hospital scale (FAST PLUS test) for the presence of large vessel occlusion in anterior intracranial circulation. The FAST PLUS test consists of two parts: the first is the well-known FAST test, which is employed in all possible cases of stroke occurrence. This test consists of the following items: Speech (scored 0-1), Facial palsy (0-1), any failure of Arm motor function (0-1), and Time (0-1). The second part of FAST PLUS test evaluates only the presence of severe arm or leg motor deficit (scored 0-1) and unilateral occurrence of its motor function deficit (scored 0-1). The FAST PLUS test will be used prospectively at the place of stroke onset by trained medical emergency technicians. The first objective of study is to evaluate the sensitivity, specificity, and the positive and negative predictive value of the test which relate to the presence of occlusion of intracranial artery (intracranial carotid artery, T occlusion and occlusion of Middle Cerebral artery segment M1 and M2). CT angiography can only diagnose the LVO. The second objective of this study is to assess inter-rater variability among stroke specialists and emergency technicians, concerning the presence of severe motor arm or leg deficit. The third objective : After implementation of the FAST TEST to clinical practice, we aim to achieve the acceleration of transport time in FAST PLUS positive patients via direct transport to Comprehensive Stroke Center to mechanical thrombectomy.

NCT ID: NCT03069014 Recruiting - Clinical trials for Mild to Moderate Alzheimer's Disease

Study of LM11A-31-BHS in Mild-moderate AD Patients

Start date: February 15, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to determine the safety of 2 doses of LM11A-31-BHS in 120 patients with Alzheimer's Disease versus placebo and to access biomarker and clinical exploratory endpoints of LM11A-31-BHS

NCT ID: NCT03053479 Recruiting - Clinical trials for Pelvic Organ Prolapse

Comparison of the Efficacy of Sacrocolpopexy, the Amreich-Richter Procedure and Transvaginal Mesh

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

Pelvic organ prolapse, POP, is a common health problem affecting up to 40% of women. Very little is known about the factors associated with surgical failure. Studies have identified a variety of risk factors: younger age, high body mass index and advanced preoperative prolapse (grade III-IV) have been associated with an increased risk of reoperation in some studies. According to some studies patients had poorer anatomical outcome after traditional repairs but were able to enjoy the same quality of life as after transvaginal mesh surgery or laparoscopic sacrocolpopexy. The purpose of this study is to assess and compare the efficacy of these three procedures in a randomized controlled trial.

NCT ID: NCT03049020 Recruiting - Clinical trials for Pelvic Organ Prolapse Recurrence

The Efficacy of Laparoscopic Sacrocolpopexy in the Treatment of Pelvic Organ Prolapse in Women With or Without Avulsion of the Levator Ani Muscle

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

Based on a prospective study, to evaluate how pre-operative pelvic floor status - the presence of injury to the musculus levator ani - may influence the results of laparoscopic sacrocolpopexy. The investigators hope to confirm or disprove the hypothesis that the presence of such injury increases the risk of post-operative prolapse recurrence

NCT ID: NCT03047538 Not yet recruiting - Blood Pressure Clinical Trials

Fixed Combination for Lipid and Blood Pressure Control

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

The aim of this study is to compare the effect of fixed and free combination of atorvastatin/perindopril/amlodipine on blood pressure and lipid levels.

NCT ID: NCT03040063 Recruiting - Limb Ischemia Clinical Trials

Complex Endovascular Approach to Treatment of Patients With Aneurysm of Popliteal Artery

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

Use of endovascular techniques - implantation of a peripheral stent graft and a peripheral flexible stent to isolate the sac of the popliteal artery aneurysm from the circulation and subsequent topical application of a thrombolytic (rtPA) to restore patency of the lower leg blood stream - will lead to a comparable or better outcome in treatment of patients with the popliteal artery aneurysm and acute critical limb ischaemia, compared to currently prevailing use of surgical treatment.
