Prophylactic Antibiotics in Endoscopic Secondary Prevention of Gastroesophageal Variceal Bleeding

Whether prophylactic antibiotics should be administered in the endoscopic secondary prevention of GVB or not is unclear. In this non-inferiority trial, we are aimed to evaluate whether prophylactic antibiotics are essential in the endoscopic secondary prevention of cirrhotic patients with gastroesophageal variceal bleeding.

VICIS - Vienna Cirrhosis Study

Patients with advanced chronic liver diseases treated at the Vienna General Hospital of the Medical University of Vienna will be offered to participate in this prospective observational trial - including an optional participation in a biobank. Clinical parameters and laboratory parameters will be recorded for all patients and patients will undergo a regular follow-up schedule with clinical visits at the Vienna General Hospital. This study is linked to a biobank with serum/plasma, ascitic fluid, urine, GI tract mucosal biopsies, liver biopsies and stool collected from the study participants.

Beta-blockers or Placebo for Primary Prophylaxis (BOPPP) of Oesophageal Varices Trial.

Research has proven that large varices can be treated with beta-blockers (a type of anti-hypertensive medication) to reduce the pressure in the veins. The management of small varices is still uncertain. This study aims to discover if beta blockers can be used in this setting. We hypothesize that beta blockers will reduce the risk of bleeding from small varices from 20% to 10% over a period of 3 years, resulting in significant cost savings to the NHS from better patient outcomes.
