The glucagon-like peptide-1 receptor agonists (GLP-1RA) are among the newest treatment options available for managing of type 2 diabetes mellitus and slowing the progression of diabetes kidney disease (DKD). Subcutaneous (SC) semaglutide (Ozempic®) is a GLP-1RA with an extended half-life of approximately 1 week. GLP-1RA are highly effective in improving glycemic control and also show other beneficial effects such as increased natriuresis; decreased blood pressure and albuminuria; reduction of oxidative stress and inflammation; delay of gastric emptying and suppress appetite; the latter may result in significant weight loss. GLP-1RA can be used in patients with advanced-stage CKD; the European Medicines Agency has approved the use of all commercially available human GLP-1 analogs up to a minimal eGFR of 15 mL/min/1.73 m2. However, studies of safety and use of these agents in renal replacement therapy are scarce. Therefore, herein we present 3 cases of patients with advanced DKD in maintenance incremental hemodialysis with 1 session per week to describe the efficacy and safety of the SC semaglutide treatment and the favorable effects on glycemic control, lowering HbA1c, albuminuria, weight, blood pressure control, and preservation of residual kidney function (RKF) during a 6-month follow-up in a hospital hemodialysis unit in Spain. These effects could produce an improvement in morbidity and mortality and could also prevent albuminuria and preserve the RKF. This may allow our patients to maintain a weekly hemodialysis session and could facilitate their inclusion in the kidney transplant waiting lists. [ABSTRACT FROM AUTHOR]
