Expanded Hemodialysis Versus Online Hemodiafiltration

"Intervention: Conversion from conventional HD to expanded hemodialysis por 1 month.~High cutoff with high retention onset dialyzers allow clearance of middle molecules, without reducing significantly serum concentration of albumin. It allows higher convective clearance in comparison to conventional hemodialysis, but it is unknown if such clearance is similar to online hemodiafiltration. Therefore, the aim of the present intervention is to compare this dialyzer with online hemodiafiltration"

"Intervention: Conversion from conventional HD to online Hemodiafiltration por 1 month.~Online hemodiafiltration has been associated with lower incidence of intradialytic hypotension in comparison to conventional hemodialysis."
