The congestive heart failure has barely improved with the medication and now she's got kidney failure that dialysis is not an option for or not working for because of some kind of complication with her diabetes.
As the long-term treatment for permanent kidney failure, dialysis is a good-news/bad-news technology.
And home dialysis is significantly cheaper than being treated in a clinic or hospital.
At that point, they may need to begin dialysis immediately, which leaves little time to consider options or learn to do complex procedures at home.
A big advantage to home dialysis is that patients can do shorter treatments more frequently than the thrice weekly sessions typically offered in centers, which makes each less physically draining and allows less fluid and toxins to build up in between.
Since changes in the kidneys of long-term dialysis patients might be due to the underlying kidney disease, and kidney changes have not been consistently seen in animals exposed to DEHP, the significance of the rat kidney changes is not clear.
But why the kidneys are not working or how long someone needs to be on dialysis is different for each person.
Hemophiliacs, patients on long-term dialysis, those who had severe trauma or major abdominal surgery like Miguel, the patient at the beginning of this chapter, and those who had a coronary artery bypass graft or other kinds of cardiac surgery had a particularly high risk of contracting hepatitis C because they often required multiple blood transfusions.
Other groups of people at higher risk of becoming infected with hepatitis C include people infected with HIV; current or former intravenous drug users, even it was a one-time occurrence; health care professionals; long-term dialysis patients; and those who received blood products or organs before 1992.
Although a transplant is initially expensive $100,000 and up, the cost of long-term dialysis is even higher.
