SANCHEZ-VILLANUEVA, Rafael J. et al. Hypersensitivity reactions to synthetic haemodialysis membranes. Nefrología (Madr.) [online]. 2014, vol.34, n.4, pp.520-525. ISSN 1989-2284.  https://dx.doi.org/10.3265/Nefrologia.pre2014.May.12552.

Undergoing a haemodialysis (HD) session poses a certain risk of hypersensitivity adverse reactions as large quantities of blood are in contact with various synthetic materials. Hypersensitivity reactions to ethylene oxide and non-biocompatible membranes, such as cuprophane, have been described in HD. Cases of hypersensitivity with biocompatible membranes, such as polysulfone, and even polysulfone-polyvinylpyrrolidone, have also been reported. In this article we describe six cases of mostly early-stage hypersensitivity reactions to HD occurring in our department, characterised by malaise, desaturation, bronchospasm and arterial hypotension, with good response to the session's temporary suspension and with reappearance in subsequent sessions that used a synthetic dialyser. No hypersensitivity reactions reappeared in successive observations when the sessions were carried out using a cellulose membrane.
