Fluid hydration to prevent post-ERCP pancreatitis in average- to high-risk patients receiving prophylactic rectal NSAIDs (FLUYT trial): Study protocol for a randomized controlled trial

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal anti-inflammatory drugs (NSAIDs) is lacking and the cost-effectiveness of the approach has not been investigated. We hypothesize that combination therapy of rectal NSAIDs and periprocedural hydration would significantly lower the incidence of post-ERCP pancreatitis compared to rectal NSAIDs alone in moderate- to high-risk patients undergoing ERCP. Methods: The FLUYT trial is a multicenter, parallel group, open label, superiority randomized controlled trial. A total of 826 moderate- to high-risk patients undergoing ERCP that receive prophylactic rectal NSAIDs will be randomized to a control group (no fluids or normal saline with a maximum of 1.5 mL/kg/h and 3 L/24 h) or intervention group (lactated Ringer's solution with 20 mL/kg over 60 min at start of ERCP, followed by 3 mL/kg/h for 8 h thereafter). The primary endpoint is the incidence of post-ERCP pancreatitis. Secondary endpoints include PEP severity, hydration-related complications, and cost-effectiveness. Discussion: The FLUYT trial design, including hydration schedule, fluid type, and sample size, maximize its power of identifying a potential difference in post-ERCP pancreatitis incidence in patients receiving prophylactic rectal NSAIDs

Behandeling van Helicobacter pylori-infectie

H. pylori infection is a very common infection of the human stomach, related to various diseases such as gastritis, ulcerative disease of the duodenum and stomach, mucosa associated lymphoid tissue lymphomas and gastric cancer. It is generally accepted that the majority of related diseases is curable once H. pylori infection is successfully eradicated. H. pylori eradication will only be achieved after administration of combination therapies including antibiotics and antacids. Resistance to metronidazole and clarithromycin is an emerging problem, leading to impairment of eradication efficacy, irrespective of the regimen administered. Eradication regimens consisting of three or four anti-H. pylori drugs are the most efficacious. Given the easy use and high convenience to the patients and the high efficacy, 1-week proton pump inhibitor (PPI)-triple therapy is preferred as the first-line therapy. Alternatively, bismuth triple therapy or the combination of antacids and bismuth triple therapy can be prescribed; however, these regimens are less convenient to the patients, the course is prolonged or the side effects occur more frequently compared with PPI-triple therap

Evaluation of three commercial serological tests with different methodologies to assess Helicobacter pylori infection

The sera of 142 Helicobacter pylori-positive and 32 H. pylori-negative patients were assessed by a desktop test (QuickVue), an enzyme-linked immunosorbent assay (ELISA) (HM-CAP), and a solid-phase, two-step chemiluminescent enzyme immunoassay (Immulite). These tests yielded sensitivities of 97, 97, and 91% and specificities of 97, 94, and 100%, respectively. In conclusion, the desktop test and the ELISA are more sensitive than the chemiluminescent enzyme immunoassay (P <0.05). The chemiluminescent enzyme immunoassay has the advantage that it is fully automate
