Background In some parts of the world, peritoneal dialysis iswidely used for renal replacement in acute renal failure. Inresource-rich countries, it has been supplanted in recent yearsby hemodialysis and, most recently, by hemofiltration and associatedtechniques. The relative efficacy of peritoneal dialysis andhemofiltration is not known.
Methods We conducted an open, randomized comparison of pumpedvenovenous hemofiltration and peritoneal dialysis in patientswith infection-associated acute renal failure in an infectious-diseasereferral hospital in Vietnam.
Results Seventy adult patients with severe falciparum malaria(48 patients) or sepsis (22 patients) were enrolled; 34 wereassigned to hemofiltration and 36 to peritoneal dialysis. Themortality rate was 47 percent (17 patients) in the group assignedto peritoneal dialysis, as compared with 15 percent (5 patients)in the group assigned to hemofiltration (P=0.005). The ratesof resolution of acidosis and of decline in the serum creatinineconcentration in the group assigned to hemofiltration were morethan twice those in the group assigned to peritoneal dialysis(P<0.005), and renal-replacement therapy was required fora significantly shorter period. In a multivariate analysis,the odds ratio for death was 5.1 (95 percent confidence interval,1.6 to 16) and that for a need for future dialysis was 4.7 (95percent confidence interval, 1.3 to 17) in the group assignedto peritoneal dialysis. The cost of hemofiltration per survivorwas less than half that of peritoneal dialysis, and the costper life saved was less than one third.
Conclusions Hemofiltration is superior to peritoneal dialysisin the treatment of infection-associated acute renal failure.
