Risk factors for massive gastrointestinal bleeding occurrence and mortality: A prospective single-center study.

BACKGROUND: Massive gastrointestinal bleeding is a life-threatening condition without a well-established definition. We aimed to analyze the characteristics, risk factors, and outcomes of patients with massive upper gastrointestinal bleeding. METHODS: Our study analyzed a prospective registry of patients admitted between 2013 and 2020 with variceal and non-variceal causes. Severe bleeding was defined as ongoing bleeding requiring transfusion of more than 2 units of packed red blood cells within 24 hours, accompanied by signs of shock. The main outcomes were 30-day and 6-month mortality, rebleeding within 7 days, persistent bleeding, and severe complications during admission. RESULTS: Out of 1213 patients, 171 had massive gastrointestinal bleeding, with a predominance of males. The massive bleeding group had higher rates of chronic kidney disease, cirrhosis, in-patient status, disseminated malignancy, alcoholism, and ASA score ≥3. All major outcomes, including 30-day mortality, 6-month mortality, rebleeding, persistent bleeding, and severe complications, were more common in the massive bleeding group. Multivariate logistic regression identified inpatient status, systemic diseases, malignancy, active bleeding in endoscopy, and severe complications as risk factors for massive bleeding and mortality. CONCLUSIONS: Inpatient status and comorbidities, especially systemic diseases, and malignancies, were associated with a higher risk of massive bleeding. Mortality was linked to chronic kidney disease, cirrhosis, severe comorbidities, and alcohol consumption. We observed increased 6-months mortality, probably related to a health status in which gastrointestinal bleeding heralded poor outcomes, some of them potentially preventable. Innovative healthcare interventions, such as Emergency Department-based intermediate care areas or Intensive Care Units, and multidisciplinary follow-up, could potentially improve survival.

Performance of the New ABC and MAP(ASH) Scores in the Prediction of Relevant Outcomes in Upper Gastrointestinal Bleeding.

Background & Aims: Several risk scores have been proposed for risk-stratification of patients with upper gastrointestinal bleeding. ABC score was found more accurate predicting mortality than AIMS65. MAP(ASH) is a simple, pre-endoscopy score with a great ability to predict intervention and mortality. The aim of this study was to compare ABC and MAP(ASH) discriminative ability for the prediction of mortality and intervention in UGIB. As a secondary aim we compared both scores with Glasgow-Blatchford score and AIMS65. Methods: Our study included patients admitted to the emergency room of Virgen de las Nieves University Hospital with UGIB (2017-2020). Information regarding clinical, biochemical tests and procedures was collected. Main outcomes were in-hospital mortality and a composite endpoint for intervention. Results: MAP(ASH) and ABC had similar AUROCs for mortality (0.79 vs. 0.80). For intervention, MAP(ASH) (AUROC = 0.75) and ABC (AUROC = 0.72) were also similar. Regarding rebleeding, AUROCs of MAP(ASH) and ABC were 0.67 and 0.61 respectively. No statistically differences were found in these outcomes. With a low threshold for MAP(ASH) ≤ 2, ABC and MAP(ASH) classified a similar proportion of patients as being at low risk of death (42% vs. 45.2%), with virtually no mortality under these thresholds. Conclusions: MAP(ASH) and ABC were similar for the prediction of relevant outcomes for UGIB, such as intervention, rebleeding and in-hospital mortality, with an accurate selection of low-risk patients. MAP(ASH) has the advantage of being easier to calculate even without the aid of electronic tools.

Intestinal-type gastric adenocarcinoma in a patient with ataxia-telangiectasia syndrome.

We introduce a 20-year-old patient, with prior diagnosis of ataxia-telangiectasia syndrome, urgently assesed because of an upper gastrointestinal bleeding, identifying in the urgent endoscopy an intestinal-type gastric adenocarcinoma as its origin.
