The study conducted by Mingyue He, MD, revealed alarming findings regarding the increased risk of potentially fatal gastrointestinal bleeding in individuals with advanced chronic kidney disease (CKD). According to the data presented at the National Kidney Foundation (NKF) Spring Clinical meeting, patients with stage 5 CKD had a 40% higher chance of being hospitalized due to gastrointestinal bleeding compared to those without CKD. Additionally, the research highlighted that individuals with stage 5 CKD faced significantly higher rates of inpatient all-cause mortality, with those not on dialysis having an adjusted odds ratio (aOR) of 2.3 and those on dialysis having an aOR of 1.9. This underscores the critical importance of monitoring and managing gastrointestinal health in CKD patients, especially those in advanced stages of the disease.
Dr. He’s study also shed light on the impact of endoscopic evaluations on patient outcomes. The research revealed that despite comparable endoscopy rates among patients hospitalized with gastrointestinal bleeding, individuals with stage 5 CKD were less likely to undergo early endoscopies (performed within 24 hours) and more prone to delayed endoscopies (performed over 48 hours later). Notably, patients with stage 5 CKD who underwent delayed endoscopies had a 60% higher chance of mortality. These findings emphasize the significance of timely endoscopic assessments in mitigating adverse outcomes in CKD patients experiencing gastrointestinal bleeding.
Dr. He pointed out various factors that could contribute to delays in endoscopic evaluations for CKD patients, including previous endoscopic procedures, electrolyte imbalances, dialysis schedules, and thrombocytopenia. She also highlighted the increased risk of anesthesia complications in individuals with advanced CKD and end-stage kidney disease (ESKD) as a potential barrier to prompt endoscopic assessments. While the study did not delve into these contributing factors, Dr. He stressed the importance of exploring the underlying reasons for delayed endoscopic evaluations in CKD patients to enhance adherence to guidelines and improve patient outcomes.
Beyond highlighting the heightened risk of gastrointestinal bleeding in patients with advanced CKD, the study revealed distinct risk factors associated with different stages of the disease. Individuals on dialysis exhibited higher rates of angiograms, ventilation, vasopressor use, blood transfusion, and prolonged hospitalizations compared to those without CKD. Moreover, patients with stage 5 CKD, irrespective of dialysis status, were more susceptible to gastrointestinal bleeding caused by ulcers or unspecified causes, as well as angiodysplasia. Conversely, kidney transplant recipients showed a significantly increased risk of diverticular bleeding post-transplant.
The findings of Dr. He’s study underscore the need for further research to elucidate the mechanisms underlying gastrointestinal bleeding in CKD patients and explore strategies to optimize clinical management. Understanding the factors influencing endoscopy timing, addressing barriers to timely evaluations, and tailoring interventions to mitigate the risk of adverse outcomes are crucial steps in enhancing the care of individuals with CKD. By expanding upon the current data and investigating the discrepancies in endoscopy practices, future studies have the potential to inform evidence-based guidelines and improve the overall prognosis of CKD patients experiencing gastrointestinal complications.
