Risk factors for upper gastrointestinal bleeding in intensive care unit patients : Role of Helicobacter pylori.
To determine the role of preexisting Helicobacter pylon infection in the development of acute upper gastrointestinal (GI) hemorrhage in intensive care unit (ICU) patients in relation to other potential predisposing risk factors.
Prospective, multicenter, cohort study.
Medical and surgical ICUs in six tertiary care Department of Veterans Affairs Medical Centers.
Eight-hundred seventy-four patients without previous Gl bleeding or peptic ulcer disease who were enrolled in a multicenter, randomized, controlled trial of prophylactic intravenous immunoglobulin to prevent ICU-assoclated infections.
This substudy of the larger intravenous immunoglobulin study only involved data analysis and had no intervention.
All patients were enrolled in the larger study where they received intravenous immunoglobulin or placebo as intervention.
Measurements and Main Results
Patients were prospectively evaluated for the development of acute upper GI hemorrhage while in an ICU.
Anti-H. pylori immunoglobulin G and immunoglobulin A concentrations were determined by enzyme immunoassay on preintervention serum samples.
Seventy-six (9%) patients had overt upper GI bleeding and a mortality rate of 49%, as compared with a 15% mortality rate in patients who did not bleed (p<. 001). (...)
