Renal Transplantation Flashcards
Where is a transplanted kidney situated?
Illiac fossa. The native kidneys tend to be left in place
What level of eGFR indicates for a kidney transplant?
7-10ml/min but it is very individual
What are the downsides of dialysis?
- Makes patients fatigued,
- Patients are in a fluid restriction and restricted diet (avoid potassium high foods),
- Women are infertile,
- Life expectancy is reduced
What are the indications for a kidney transplant?
- Live longer and better with a better QoL, less time in hospital, restoration of fertility and dietary freedom. It is also cost saving
What patients are unsuitable for a kidney transplant?
- Reduced life expectancy - Patients who are unlikely to survive 5 years even with transplant or those with co-morbidities.
- Surgical contraindications include no bladder or calcified blood vessels.
Medical contraindications - Hyper/hypo-tension or diseases which will reoccur in the transplant (malignancy or chronic infections)
What are examples of diseases which are common in dialysis clinic and transplant clinics
Dialysis - Renovascular disease, T2 diabetic nephropathy, vasculitis.
Transplantation - APKD, glomerulonephritis, reflux nephropathy, T1 diabetic nephropathy and obstructive uropathy
What are the types of kidney donors?
- Deceased donors,
- Living donors - can come from relatives, friends or altruistic donors. Living donors tends to have better kidneys which have a longer survival
What is the UK national kidney sharing scheme?
- Starts with altruistic donor which sets of a chain of transplantations. Each recipient has a person willing to donate a kidney but doesn’t match them.
What are some potential immunosupression drugs to prevent organ rejection?
- Basiliximab.
- Tacrolimus (calcineurin inhibitor)
- Mycophenolate mofetil (inhibits T and B cell proliferation)
- Steroids
What are the two forms of organ rejection?
- Cell mediated rejection - Interstitial inflammation and tubulitis. Easily treated with steroids if caught early.
- Antibody-mediated rejection - Endothelial swelling, glomerulonephritis and peri-tubular capillaries. These are donor specific antibodies which is hard to treat
What are the complications of kidney transplantation
- Rejection
- Infection: Common infections (Chest infections, UTIs), reactivation infections (CMV) and uncommon organisms (pneumocystis Jiovecii). Treat by reducing immunosupression and antibacterials/virals.
- Malignancy: Kaposi sarcoma, skin, non-hogkins, kidney (increased risk in organ which has been transplanted) Treatment is reducing immunosupression or chemotherapy.
What is an infection often only seen in transplantation patients?
Pneumocystis Jirovecii
