In our institution, a change of practice was implemented and the central venous catheter (CVC) placement for all autologous PBSC collections was abandoned in favor of a careful evaluation of peripheral venous access (PVA) for each individual patient.

The patient was hospitalized with an antibody-mediated transplant rejection for which treatment with methylprednisolone, TPE with a 40 g/L albumin solution as a replacement fluid, and intravenous immunoglobulins was initiated. After four TPE treatments, the patient developed gastrointestinal complaints and muscle weakness. Despite daily oral bicarbonate supplementation, laboratory tests revealed a hyperchloremic metabolic acidosis: bicarbonate 11.7 mmol/L, chloride 111 mmol/L, and sodium 138 mmol/L. Metabolic acidosis due to citrate accumulation was ruled out with a normal total-to-ionized calcium ratio. After treatment with intravenous bicarbonate supplementation, the symptoms disappeared. Analysis of the albumin solution showed a chloride concentration of 132 mmol/L. This is the first case that describes severe metabolic acidosis after multiple sessions of TPE with an albumin solution in a patient with impaired renal function. The hyperchloremic metabolic acidosis is the result of administration of large volumes of an albumin solution with high chloride concentrations.
