Prognostic factors associated with upper gastrointestinal bleeding based on the French multicenter SANGHRIA trial

Proton pump inhibitor therapy after transcatheter angiography in refractory nonvariceal acute upper gastrointestinal bleeding patients: a cohort study

BACKGROUND

Transcatheter angiography (TA) could help to diagnose and treat refractory nonvariceal upper gastrointestinal bleeding (NVUGIB). Proton pump inhibitors (PPIs) are the key medication for reducing the rebleeding rate and mortality and are usually continued after TA. It is unknown whether high-dose PPIs after TA are more effective than the standard regimen.

METHODS

We retrospectively collected data from patients who received TA because of refractory NVUGIB from 2010 to 2020 at West China Hospital. 244 patients were included and divided into two groups based on the first 3 days of PPIs treatment. All baseline characteristics were balanced using the inverse probability of treatment weighting method. The 30-day all-cause mortality, rebleeding rate and other outcomes were compared. The propensity score matching method was also used to verify the results.

RESULTS

There were 86 patients in the high-dose group and 158 in the standard group. The average daily doses of PPI were 192.1 ± 17.9 mg and 77.8 ± 32.0 mg, respectively. Cox regression analysis showed no difference in the 30-day all-cause mortality (aHR 1.464, 95% CI 0.829 to 2.584) or rebleeding rate (aHR 1.020, 95% CI 0.693 to 1.501). There were no differences found in red blood cell transfusion, hospital stay length and further interventions, including endoscopy, repeating TA, surgery and ICU admission. The results were consistent in the subgroup analysis of patients with transcatheter arterial embolization.

CONCLUSION

In refractory NVUGIB patients who received TA, regardless of whether embolization was performed, high-dose PPI treatment did not provide additional benefits compared with the standard regimen.

Characteristics, Outcomes, and Risk Factors for Upper Gastrointestinal Bleeding in Inpatients - A Comparison with Outpatients

Objective The study objectives were to clarify the clinical findings and the causes of intractability and mortality of upper gastrointestinal (UGI) bleeding in inpatients. Methods The patients were divided into Inpatient (Ip) and Outpatient (Op) onset groups, and their characteristics, clinical and bleeding data, and outcomes were compared. Patients or Materials Our study included 375 patients who developed UGI bleeding during hospitalization or were admitted after being diagnosed with UGI bleeding in an outpatient setting from January 1, 2015, to June 30, 2020. Results The Ip group had worse general condition; increased percentages of comorbidities; and more common use of proton pump inhibitor, anti-coagulant, and steroid than the Op group. Compared with the Op group, the Ip group had lower serum albumin levels and platelet counts at the onset of bleeding, whereas rebleeding, mortality, and bleeding-related death rates were higher. Multivariate analysis of the Ip group revealed that the risks of rebleeding included endoscopic high-risk stigmata, maintenance dialysis, and duodenal bleeding, whereas the risks of mortality were gastric ulcer and a Charlson Comorbidity Index update score of ≥3. Conclusion UGI bleeding in the Ip group was associated with higher rebleeding and mortality rates. Because of their poor general health condition, the pathology of UGI bleeding in these patients may differ from that of patients with common UGI bleeding. A different approach for the care and prevention of UGI bleeding in inpatients is required.

Cancer, platelet distribution width, and total protein levels as predictors of rebleeding in upper gastrointestinal bleeding

BACKGROUND

Rebleeding is associated with poor outcomes in upper gastrointestinal bleeding (UGIB). Identifying predictors of rebleeding can assist in risk assessment. The aim of the study is to investigate the factors affecting rebleeding in patients with UGIB admitted to the emergency department.

METHODS

This retrospective, observational, cross-sectional study was conducted on patients with UGIB presented to the emergency department. Patients who did not arrest in the first 24 h, who were not diagnosed with GI malignancy, and who were clinically diagnosed with UGIB were included in the study. Patient demographic characteristics, hemodynamic parameters, patient parameters, and bleeding that may affect rebleeding were evaluated. The primary endpoint was rebleeding within 7 days.

RESULTS

The study included 371 patients. A total of 55 patients (14.8%) had rebleeding within 7 days, and 62 patients (16.7%) presented without bleeding manifestations. Rebleeding rates were higher in those who presented with bloody or coffee-ground vomitus, had a diagnosis of cancer, had blood in their nasogastric tube, and had peptic ulcers due to endoscopy. Mean cell hemoglobin concentration, lymphocyte, albumin, and total protein values of patients with rebleeding were low; red blood cell distribution width, neutrophil count, platelet distribution width (PDW), and neutrophil lymphocyte ratio were high. In-hospital mortality and 30-day mortality values of patients with rebleeding were significantly increased. In the multivariate analysis, cancer, PDW, and total protein levels were statistically significant.

CONCLUSION

The presence of cancer, low total protein level, and high PDW are effective parameters in predicting 7-day rebleeding in patients with UGIB admitted to the emergency department.
