This study found that prealbumin and d-dimer are independent predictors for rebleeding in NVUGIB patients, showing superior predictive value compared to traditional scoring systems. They are promising markers for assessing severity and prognosis in NVUGIB practice.
Background Determining the risk stratification of nonvariceal upper gastrointestinal bleeding (NVUGIB) plays a vital role in treating upper gastrointestinal bleeding (UGIB). Traditional scores like Glasgow-Blatchford score (GBS), Rockall score (RS), and AIMS65 score have been widely utilized in UGIB practice, however exhibiting limited practical use due to relative lack of user-friendly characters. Prealbumin as a nutritional indicator and d-dimer as a fibrinolytic activity monitor, are generally used to evaluate the overall nutritional and fibrinolytic condition in UGIB patients. Aims Here, we explored the predictive value of these two markers in NVUGIB for evaluating severity and prognosis including rebleeding and surgery intervention. Methods One hundred and eighty-five patients suffering NVUGIB were enrolled. Their GBS, RS, and AIMS65 score, routine laboratory test results including prealbumin and d-dimer were determined after admission. Multivariate regression analysis was performed to define the independent predictors of rebleeding. ROC curves were generated to compare the suitability of prealbumin, d-dimer, and scores for rebleeding prediction. Results The NVUGIB patients with rebleeding exhibited higher scores, white blood cell counts, d-dimer, CRP, proportion of surgery intervention, and longer hospital stay, but lower hematocrit, hemoglobin, calcium, prealbumin, and fibrinogen than those without rebleeding. The multivariate regression analysis demonstrated that prealbumin and d-dimer were independent predictors for rebleeding. Values of prealbumin and d-dimer were correlated with hospital stay, ulcer degrees, and surgery demand. The ROC curve analyses showed that prealbumin and d-dimer exhibited superior prediction value over the scoring systems. Conclusions Prealbumin and d-dimer are promising predictors for severity and prognosis in NVUGIB practice.
