In June 1968, a colleague and I reported the case of a 14-year-old malnourished girl with end-stage renal disease who was dialysed daily, except Sunday, for 8-14 hours overnight.1 She had an excellent response, went home on this regime and eventually received a transplant. In October of the same year, we described our experience with 22 patients on home hemodialysis, 20 of whom were dialyzed 10 hours overnight 3 times weekly with the patient asleep for most of the procedure.2 This regime was initiated by groups at the Royal Free Hospital in England3 and in Seattle.4
My question to Andreas Pierratos, the author of "Nocturnal hemodialysis: dialysis for the new millennium,"5 is this. To which millennium was he referring?
