Unfortunately, it is not uncommon to go into renal failure following an acute episode of sepsis. Overwhelming sepsis can affect all areas and organs of the body and sometimes people can go into multi organ failure. Basically, the body is so overwhelmed by infection that is shuts down organ functions as a protective mechanism and sometimes function can be recovered and sometimes not. It sounds as if you went into an Acute Renal Failure episode due to your sepsis, which would be from what is called a pre-renal cause and have now go into Chronic Renal Failure as a result of this. There is a chance of recovering normal function following an episode of ARF, however, if you are also diabetic and have other health problems, then it is less likely. Also, yes, the fact that you had this massive sepsis could have speeded up the severity of your diabetes causing you to have what is called diabetic nephropathy.
Most patients with CRF are also anaemic and this is known as renal anemia and is due to the fact that as the kidneys are not functioning as they should, EPO is no longer produced in the body - this stimulates the production of red blood cells. If this is not happening, then it needs to be corrected with injection of EPO or its equivalent, which I pressume is the drug you are being given?
If your anemia is under control with this, then a transplant should not be a problem. However, there is always the risk that if a diabetic has a transplant, then they could go onto develop nephropathy in the transplanted kidney too. Is your blood sugar level well controlled? If it is, then there is less chance of this happening. Some centres now actually perform dual renal pancreatic transplants for diabetic patients and they have been very successful. Is there any chance that you could get one of these?
Hope this helps?
