Abstract
BACKGROUND: Adequate fluid removal to achieve euvolemic status can be difficult in patients with incident peritoneal dialysis (PD). Limited treatments such as increased high dextrose PD solutions and icodextrin are currently available. We reported four incident PD patients whose' ultrafiltration volume was increased after sodium-glucose cotransporter-2 inhibitors. CASE PRESENTATION: The four reported cases were diabetic kidney disease stage 5 (cases 1-3) and IgA nephritis (case 4) patients whostartedt PD because of acute pulmonary edema (case 1 and 3), nausea vomiting (case 2), and hyperkalemia (case 4). They had an ultrafiltration volume of 700-1000 ml per day but hpersistentted peripheral pitting edema or pulmonary edema. Their ultrafiltration volincreased after dapagliflozin 5 mg daily, and the fluid overload symptoms ere improved. No hypotension, or hypoglycemia was found, and the urine was not increased during dapagliflozin treatment. CONCLUSIONS: SGLT-2 inhibitors may increase ultrafiltration in incident PD patients. More studies are needed to support the safety of SGLT-2 inhibitors in PD patients.
