I had been advised to switch to HDF as well by various people. I do daily, nocturnal hemodialysis currently. I dialyze for seven and a half hours, five times a week. After hearing all the buzz, I thought maybe I should also try HDF. Daily nocturnal HDF would be a killer combination - the benefits of longer duration and a higher frequency along with convective clearances that HDF gives.
Or so I thought.
I checked with some experts in the area of more frequent, longer duration dialysis. There was a consensus that for those who do more frequent, longer duration dialysis, there is enough toxin removal. In fact, some stuff was removed so well, phosphate for example, that it had to be supplemented (like for me). The levels of Beta 2 Microglobulin and homocysteine were also normalised. There was also a fear that the things you don’t want removed like amino acids and drugs would be removed. They did not know anyone on this modality. Some also felt that the cost of the treatment would shoot up unnecessarily and water quality monitoring would need to be bettered.
All this put Daily Nocturnal HDF in the “not recommended” category.
Good for me.
