Dialysis-associated allergic reactions during continuous renal replacement therapy and hemodialysis: A case report

Dialyzer reactions are long-appreciated complications of dialysis. Despite advances in dialysis machines and membranes, these life-threatening reactions still occur. It is imperative to recognize potential dialyzer reactions when assessing adverse dialysis events as reexposure to dialytic treatments could be life threatening. We present the case of a 72-year old woman with dialysis-requiring anuric acute kidney injury who experienced acute hypotension and cardiopulmonary arrest during both continuous renal replacement therapy and a subsequent hemodialysis treatment. We concluded that she had an anaphylactic reaction to an unidentified component of the dialysis equipment. Identification, work up, treatment, and reporting of dialyzer reactions are discussed in the context of this case.
