Objective: Congestive heart failure (CHF) affects millions of Americans and
is the leading cause of hospitalization in adults over 65 years of age. Small
case reports have described the use of icodextrin to induce ultrafiltration
(UF) as a treatment of CHF in patients who are not at end-stage renal disease.
This abstract reviews these published cases.
Methods: Literature search based on PubMed submissions using keywords
icodextrin, ultrafiltration, congestive heart failure, cardiomyopathy,
peritoneal dialysis. Contact was also made with Baxter Renal Division seeking
additional cases.
Results: 27 patients with severe CHF treated with icodextrin were
identified. Pretreatment ejection fractions ranged from <20% to 35%. Some
patients were described as having "normal" glomerular filtration
rate, the others were CKD stages 3 and 4. Single nocturnal exchanges of
icodextrin were prescribed but in some cases 2 exchanges a day were used. The
mean UF volume was 1046 mL/day. No hypotension was reported. Patients
frequently admitted to the hospital prior to UF had reduction in
hospitalizations. In those that documented ejection fraction the cardiac
function was noted to improve with UF. All patients had improvement in their
clinical status and New York Heart Association classification. Two of the 27
required additional peritoneal dialysis exchanges for increased UF. Only 1
report documented peritonitis rates: the rate was 1 episode per 100
patient-months. See poster presentation for summary of data.
Conclusions: Icodextrin-based UF has been successfully employed to control
severe CHF refractory to medical management. The reduction in hospitalizations
suggests that peritoneal UF with icodextrin can be cost-effective and lead to
improvement in function and quality of life.
