The Effect of Carvedilol VS Endoscopic Therapy in Primary Prophylaxis of High-risk Esophageal Gastric Variceal Bleeding

The study is a randomized controlled trial. Patients randomly enter into two treatment groups: 1)the Carvedilol group and 2)the endoscopy group. Treatment allocation is by block randomization, with an two-to-one ratio for Carvedilol and endoscopy. The results are concealed in opaque envelopes. The dose of Carvedilol is titrated according to ...

Registry Trial of the Effectiveness of Platelet Rich Plasma for Chronic Non-Healing Wounds

The proposed investigation is designed to solicit a large number of patients (N=1,500) with non-healing wounds (Diabetic Foot Ulcers, Venous Ulcers, or Pressure Ulcers) that have not responded to standard wound care in the previous 30 days or more. A prospective, interventional, single-blinded, controlled, registry trial will be used. Data ...

Phase N/A

VLU Non-inferiority Study Comparing a Dual Action Pneumatic Compression Device to Multi-layer Bandaging

Participants with a chronic venous leg ulcer will participate in a 2 week run in phase using standard of care multi-layer bandaging before being randomly assigned to either treatment using a dual action pneumatic compression device or multi-layer bandaging for up to 16 weeks. Participants will be seen in clinic ...

Phase N/A

The Effect of Carvedilol Vs Propranolol in Cirrhotic Patients With Variceal Bleeding

The study is a randomized controlled trial. Patients randomly enter into two treatment groups: 1)the Carvedilol group and 2)the Propranolol group. Treatment allocation is by block randomization, with an equal number for Carvedilol and Propranolol. The results are concealed in opaque envelopes. The dose of non-selective β-blocker(NSBB) is titrated according ...

Phase

Validation of Esophageal Variceal Grading: A Comparative Study of Upper Gastrointestinal (GI) Endoscopy and Capsule Endoscopy

Up to 35% of patients with cirrhosis will develop esophageal varices, which carry with them a 1-year and 3-year bleeding rate of 33% and 41%, respectively. Screening for varices with a video endoscopy is limited by its cost, patient compliance, and the risks of sedating a patient with portal hypertension. ...

A Randomised Study to Assess Betadine in the Groin Wound of Patients Undergoing Primary Varicose Vein Surgery

Introduction. Varicose vein surgery is common. Worldwide, the commonest indication for this type of surgery is cosmesis. However, there are also some medical indications, including venous eczema, lipodermatosclerosis and venous ulceration. The surgery is usually straight forward and can in most instances be done as a day case. Patient and ...

Pilot Study to Asses the Function and Patency of Polyester-Coated Composite Bypasses From Autologous Varicose Veins

The ProVena trial is a non-randomised multi-centre trial, aiming to assess the suitability of the ProVena vein support. Currently, autologous veins are preferred to prosthetic grafts (Klinkert et al. 2004), but they are not considered to be suitable if they are varicose. Some early data indicate that these veins can ...

Phase N/A

Dose-response Relationship Study of S42909 on Leg Ulcer Healing

S42909 is an inhibitor of -Nicotinamide Adenine Dinucleotide Phosphate (NADPH) oxidase which also inhibits vascular leukocyte adhesion to endothelial cells, Matrix Metalloproteinase-2 (MMP-2) and Plasminogen Activator Inhibitor-1 (PAI-1) activity. It is proposed for development in the treatment of venous and mixed leg ulcers. This proof of concept study is a ...
