RESUMEN
BACKGROUND: Despite the progress in endoscopic hemostasis and pharmacological treatment, the mortality rate of peptic ulcer bleeding remains at 5-10%. Rebleeding after peptic ulcer bleeding is believed to be a risk factor for mortality. This study aimed to evaluate whether renal dysfunction is a predictor of rebleeding after endoscopic hemostasis in patients with peptic ulcer bleeding. METHODS: In this retrospective study, consecutive patients with peptic ulcer bleeding who underwent endoscopic hemostasis at our Hospital from January 2010 to December 2018 were enrolled. The relationship between rebleeding within 30 days after endoscopic hemostasis and the patients' admission and endoscopic characteristics were analyzed using univariate and multivariate regression models. RESULTS: Out of 274 patients with peptic ulcer bleeding, 17 (6.2%) patients experienced rebleeding. In the analysis of the patients' admission characteristics, estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2 was an independent risk factor for rebleeding (odds ratio 4.77, 95% confidence interval 1.168-18.211, p = 0.03). Patients with eGFR < 15 mL/min/1.73 m2 with or without hemodialysis had the highest rebleeding rate at 36.8%. With respect to endoscopic characteristics, the rate of rebleeding was associated with combination therapy (p < 0.0001) and active bleeding (p = 0.03). CONCLUSION: Renal dysfunction might be an independent risk factor for rebleeding after endoscopic hemostasis in patients with peptic ulcer bleeding.

A 44-year-old man was administered Niflec® containing macrogol 4000 as a bowel cleanser for colonoscopic examination. Immediately after ingestion, he experienced oral cavity discomfort and nasal congestion, followed by acute urticaria and presyncope. His systolic blood pressure and peripheral capillary oxygen saturation dropped to 66mmHg and 89%, respectively. Fluid infusion, as well as steroid and epinephrine administration, improved his symptoms. Skin prick tests were then performed using Niflec®, macrogol 4000, and Actosin® ointment (containing macrogol 4000), all of which were positive. Therefore, the patient was diagnosed with anaphylactic shock caused by macrogol 4000 included in Niflec®. Macrogol present in bowel cleansers used for colonoscopy rarely causes anaphylactic shock. However, clinicians need to be mindful of this risk. Prompt and appropriate treatment is needed should this condition occur.
