Loop diuretic use at the time of peritoneal dialysis (PD) is not associated with improved outcomes, according to data presented during Kidney Week 2021, a virtual meeting of the American Society of Nephrology.
Jiacong Luo, MD, of DaVita Clinical Research in Minneapolis, Minnesota, and colleagues conducted a retrospective study involving electronic health records and US Renal Data System claims data. The investigators assessed outcomes from day 91 of PD through death, loss to follow-up, or study end (December 31, 2014). The study included patients who started PD at a large dialysis organization from January 1, 2006 to June 30, 2014.
The hospitalization rate during follow-up was 1.77 admissions per patient-year among the 792 patients initiating PD with a loop diuretic prescription compared with 1.75 admissions per patient-year for the 1363 patients without such a prescription, the investigators reported. These between-group differences were not statistically significant. The 2 groups had similar mortality rates, with crude rates of 0.21 and 0.18 deaths per patient-year, respectively.

Dr Luo and colleagues found no substantial difference between the groups with respect to serum potassium levels, renal Kt/V, and time to transition to hemodialysis.
Previous research has shown that loop diuretic use at the time of dialysis initiation among patients receiving hemodialysis is associated with a lower hospitalization rate and other favorable outcomes.
