Randomized Controlled Trial Comparative Study
A randomized controlled study on the effects of acetate-free biofiltration on organic anions and acid-base balance in hemodialysis patients.
Metabolic acidosis correction is achieved by the transfer of bicarbonate and other buffer anions in dialysis. The aim of this study was to evaluate changes in the main anions of intermediary metabolism on standard hemodiafiltration (HDF) and on acetate-free biofiltration (AFB). A prospective, in-center, crossover study was carried out with 22 patients on maintenance dialysis. ⋯ The sum of postdialysis unusual measured organic anions (OA) were higher in HDF compared to AFB (P < 0.05). AFB achieves an optimal control of acid-base equilibrium through a bicarbonate substitution fluid. It also prevents hyperacetatemia and restores internal homeostasis with less production of intermediary metabolites.

Kidney injury with concomitant hemodialysis is a common finding in perioperative care of liver transplant patients. The aim of this study was to evaluate disturbances in acid-base status, electrolyte balance and citrate accumulation during hemodialysis with regional citrate anticoagulation in perioperative care of liver transplant recipients. A retrospective, single center evaluation was conducted of patients with severe liver dysfunction receiving renal replacement therapy in the perioperative care of liver transplantation in a multidisciplinary ICU of a university hospital. ⋯ Hemodialysis using regional citrate anticoagulation remains a challenge in the perioperative care of liver transplant recipients. Major attention must be paid to acid-base disturbances and citrate accumulation within 48 h after dialysis initiation. Nevertheless, regional citrate anticoagulation in liver dysfunction is a feasible and valuable tool, when limitations and pitfalls are adequately considered.
