BACKGROUND & AIMS A new generation of oral anticoagulants (nOAC), which includes thrombin and factor Xa inhibitors, has been shown to be effective, but little is known about whether these drugs increase patients' risk for gastrointestinal bleeding (GIB). Patients who require OAC therapy frequently have significant comorbidities and may also take aspirin(More)
The recently introduced new oral anticoagulants (nOAC) carry a higher gastrointestinal bleeding risk compared to traditional antithrombotic therapy. Current diagnostic coagulation tests are not accurate enough to determine the level of coagulopathy. Besides that, the lack of a specific antidote leaves the endoscopist unsure how to achieve hemostasis during(More)
BACKGROUND & AIMS Natural killer (NK) cells play a major role in anti-viral immunity as first line defense and regulation of virus-specific T cell responses. This study aimed to investigate phenotype and function of NK cells in patients with chronic hepatitis B virus (HBV) infection and to study the effect of anti-viral therapy. METHODS Peripheral blood(More)
Natural killer cells (NK) are one of the key players in the eradication and control of viral infections. Infections with the hepatitis B virus (HBV) may lead to persistence in a subgroup of patients, and impaired NK cell functions have been observed in these patients. Crosstalk with other immune cells has been shown to modulate the function of NK cells. We(More)
There is increasing evidence that the function of NK cells in patients with chronic hepatitis B (CHB) infection is impaired. The underlying mechanism for the impaired NK cell function is still unknown. Since myeloid dendritic cells (mDC) are potent inducers of NK cells, we investigated the functional interaction of mDC and NK cells in CHB and the influence(More)
Acute lower gastrointestinal bleeding (LGIB) is diverse in origin and can be substantial, requiring urgent hemostasis. Hemospray is a promising novel hemostatic agent for upper gastrointestinal bleeding (UGIB). It has been claimed in a small series that the use of Hemospray is also feasible in LGIB. We aimed to expand our knowledge of the application of(More)
UNLABELLED Gastroesophageal variceal bleeding in patients with cirrhosis is associated with significant morbidity and mortality, as well as a high rebleeding risk. Limited data are available on the role of transjugular intrahepatic portosystemic shunt (TIPS) with covered stents in patients receiving standard endoscopic, vasoactive, and antibiotic treatment.(More)
BACKGROUND Hemospray TM (TC-325) is a novel hemostatic agent licensed for use in nonvariceal upper gastrointestinal bleeding (NVUGIB) in Europe. GOALS We present the operating characteristics and performance of TC-325 in the largest registry to date of patients presenting with NVUGIB in everyday clinical practice. METHODS Prospective anonymized data of(More)
Germ-free HLA-B27 transgenic (TG) rats do not develop colitis, but colonization with specific pathogen-free (SPF) bacteria induces colitis accompanied by immune activation. To study host-dependent immune responses to commensal caecal bacteria we investigated cytokine profiles in mesenteric lymph node (MLN) cells from HLA-B27 TG versus nontransgenic (non-TG)(More)
BACKGROUND Achalasia is characterized by a functional esophagogastric junction (EGJ) obstruction. The functional luminal imaging probe (EndoFLIP) is a method to assess EGJ distensibility. In a homogeneous group of newly diagnosed achalasia patients treated with pneumatic dilation (PD), we aimed (i) to determine whether the assessment of EGJ distensibility(More)
