Hypersensitivity reactions during hemodialysis related to the use of acetate dialysate. A case report.

A patient developed a hypersensitivity reaction two weeks after being put on hemodialysis with acetate dialysate. The reactions appeared exclusively during hemodialysis and were relieved immediately after its termination. These allergic manifestations disappeared with substitution of bicarbonate for acetate dialysate and reappeared upon rechallenge with acetate dialysate.
