Gonzalez Suarez   \nKidney360 6: 1641–1642, 2025. doi: [https://doi.org/10.34067/KID.0000000994](https://doi.org/10.34067/KID.0000000994)  \nAngiodysplasia is an important cause of acute and chronic gastrointestinal (GI) bleeding.1 It can occur throughout the GI tract, more frequently seen in the cecum and right colon, but may also be found in small bowel and stomach. Clinical presentation ranges from overt bleeding to occult blood loss or subtle iron deﬁciency anemia, often resulting in recurrent bleeding over weeks or months, or persistent iron deﬁciency despite iron supplementation.2  \nAngiodysplasia has been described as a common type of GI bleeding requiring hospitalization in patients with advanced CKD.3,4 Pathogenesis is multifactorial, including chronic mucosal hypoxia, vascular degeneration, uremiarelated platelet dysfunction, which increase the risk of bleeding.5 In addition, anticoagulation, commonly used in this population, makes bleeding more pronounced. The prevalence and risk of bleeding increase with the length and severity of renal disease, especially with the vintage of patients on hemodialysis.6  \nEndoscopy plays a central role in the diagnosis and management of angiodysplasia-associated GI bleeding (AGIB); however, lesions can sometimes be missed,2 particularly in the small bowel because of lack of visualization. In patients with CKD, angiodysplasias are most frequently found in the jejunum.4 In addition to the difﬁcult location of angiodysplasias in this population, Garg et al. described that patients with advanced CKD and ESKD are less likely to receive endoscopic assessments, despite their increased mortality risk.7  \nTariq et al.8 examined the US Nationwide Inpatient Sample (NIS) database from 2009 to 2014, and demonstrated an increasing trend of AGIB in patients with ESKD, with elevated risk factors linked to advanced age, Black race, hypertension, and smoking. Individuals aged 75 and older were particularly at higher risk. The likelihood of AGIB was signiﬁcantly higher among hospitalizations of Black patients.  \nRecently, He et al.9 conducted a retrospective study using the NIS database from 2016 to 2019 to evaluate inpatient outcomes of all-cause GI bleeding in patients with advanced CKD, ESKD, and kidney transplant recipients, compared with those without CKD. They found that nonvariceal upper GI bleeding was the most common cause of GI bleeding in all patients (38.7%) . Among patients with advanced CKD, unspeciﬁed GI bleeding was most frequent, followed by nonvariceal GI bleed. After excluding unspeciﬁed gastrointestinal bleeding, the main causes were gastric/duodenal bleeding, angiodysplasia, and diverticular bleeding. Notably, patients with ESKD were less likely to undergo an endoscopy, and among those who did, the procedure was usually performed more than 48 hours after admission, showing a delay in diagnosis and management for this population. By contrast, kidney transplant recipients received similar management to patients without CKD. Several factors may contribute to these disparities, including the greater clinical complexity and higher comorbidity burden inpatients with ESKD, which can increase the procedural risk. In addition, delayed recognition of GI bleeding may occur because of subtle or nonspeciﬁc symptoms, with anemia often attributed to chronic disease rather than active bleeding.  \nIn this issue, He et al.10 conducted a retrospective cohort study of using the 2022 NIS database and the Nationwide Readmissions Database to evaluate the incidence, outcomes, and readmissions associated with AGIB in patients with CKD. International Classiﬁcation of Diseases-10 clinical modiﬁcation codes were used to identify adult patients hospitalized with AGIB, and they were stratiﬁed into patients with no CKD, early CKD (stage 3), advanced CKD (stage 4 and stage 5 not on dialysis), kidney failure (KF, ESKD, or CK","cbCaikrODBl9OfKE","https://ap.wps.com/l/cbCaikrODBl9OfKE","pdf",166794,"English","# Angiodysplasia and GI bleeding in CKD\n## Clinical features and risk mechanisms\n## Diagnostic challenges and endoscopy limitations\n## Evidence from national inpatient datasets\n## Incidence, outcomes, mortality, and readmission in CKD","[{\"question\":\"Why does angiodysplasia lead to gastrointestinal bleeding in CKD and ESKD?\",\"answer\":\"Angiodysplasia can cause bleeding throughout the GI tract.
