Objectives: • Identify the various entities that support the donation process • Review the three phases of donor management and the corresponding timeframes • Review the criteria that is utilized for patients to be placed on the waitlist • Discuss the factors involved for transplant candidate evaluation
Questions to Run On: How can I utilize this information on donor management and transplant candidate criteria to improve donation practice in my hospital?
Recipient Workup From Authorization to Allograft
Questions to Run On • Describe the criteria that is utilized for patients to be placed on the waitlist. • Identify the factors involved for transplant candidate evaluation. What are the considerations for living donors?
Kidney Disease Outcome Quality Initiative ( K/DOQI) Staging • K/DOQI created the standardization of clinical practice guidelines. • Two primary markers are used to stage Chronic Kidney Disease (CKD). Abnormalities in serum and urine lab tests: • BUN, Creatinine • Level of Kidney function as measured by Glomerular Filtration Rate (GFR).
Who Are Our Patients? • Stages of Kidney Failure- K/DOQI Staging:
Who can be listed? • A patient must be in stage 4 or 5 End Stage Renal Disease (ESRD) • Renal failure must be chronic and irreversible • GFR must be <20 to accrue wait time • A live renal transplant may be completed prior to the initiation of dialysis and GFR does not need to be <20.
Kidney Pancreas Transplant • The goal of kidney pancreas transplant is to cease the need for insulin dosage and to ease the suffering of sequelae of diabetes such as: • Gastroparesis • Renal Failure • Retinopathy • Neuropathy • Accelerated Cardiovascular disease • Improves quality of life • Patients receive a kidney/pancreas transplant as Type 1 diabetes has caused irreversible damage to both pancreas and kidney
Candidate Evaluation • Physiologically the potential candidate needs to be able to withstand the transplant procedure itself and have a lower risk of long term morbidity and mortality. • If the potential candidate is able to resolve contraindications found at initial assessment, then they may be re-assessed. • Older age, in itself, is not a contraindication.

Pre-Transplant Lab Tests • CBC • PT/PTT, inr • CMP • LFT’s • U/A, urine Cx, UPC ratio (If not anuric) • Serologies • HBsAb, HBsAg, HBcAb, HIV, HCV pcr, CMV, EBV, HSV, VZV • PSA (males over 50) • PPD • HgB A1c • Pregnancy eval if appropriate • ABO x 2 • HLA tissue typing and identification of potential DSA’s • Panel of Reactive Antibodies (PRA)
Pre-Transplant Waitlist & Evaluation Process • Potential recipient meets with Multi–Disciplinary Team • Potential recipient receives education regarding the risks and benefits of transplant, medical and financial acceptability, tests that will be required, and the organ allocation process. • Potential recipient completes work up and lab tests. • All candidates added to the transplant waitlist must be approved through the Patient Selection Committee. • Testing for any potential living donor will be done after the patient waiting for an organ is placed on the active transplant waitlist. • When a patient is on the active waitlist, he/she must follow up with transplant team bi-annually until the transplant has occurred.
Absolute Contraindications To Transplantation • Severe, untreatable heart or lung disease • Active or uncontrollable cancer • Current alcohol abuse or drug addiction • Uncontrollable infection • Uncontrollable HIV infection • Failure of other organs that will not improve with transplant. • Limited life expectancy • History of non-compliance medical/dietary recommendations pre-transplant
Living Donation – Informed Consent Education is imperative to enable the potential living donor to understand all aspects of the donation process, especially the risks and benefits. The goal of informed consent is to ensure that a potential donor understands: • That he or she will undertake risk and will receive no financial benefit from the donor nephrectomy • That he or she may be at risk for psycho/social issues: depression or anxiety related to complication from surgery, feelings of burden, body image, family tensions, loss of employment and related financial or emotional concern. • That there are general risks of the operation.
Living Donor Testing • H & P • Labs: CBC, CMP, LFT’s, Serologies, HLA tissue typing, Cross match, Lipid panel, U/A, Urine culture, UPC ratio, pregnancy evaluation, ABO, and any other lab tests that may be indicated. • Nephrology/Urologic evaluation • CXR • ECG • Cardiac stress test for donors >50 years • MRI, angiography, 3D CT, CT angiogram/Urogram • Psychosocial evaluation
Transplant procedure • The patient is anesthetized and a central venous catheter and urinary catheter are placed. • The bladder is decontaminated with antibiotic solution • The usual placement of the kidney is extraperitoneal in the iliac fossa. • Pancreas will also be placed extraperitoneally • Vascular anastamosis will be to iliac artery and vein. The kidney should turn pink and produce urine immediately. • Pancreas head will either be anastomosed to small bowel (enteric drained)or to bladder (bladder drained) • Approximated 2 liters of pancreatic fluid will be reabsorbed if enteric drained. If bladder drained, these pancreatic fluids will be excreted and may cause fluid depletion. • The donor ureter is anastomosed to the recipient bladder and a double J stent is placed. This stent facilitates healing across the anastamosis and will be removed in the transplant clinic in 4-6 weeks via cystoscopy • After organ(s) are placed a final check for hemostasis and the positioning of the vessels is done and a standard wound closure is done.
Immunosuppressive Therapy All patients who receive a transplant are placed on a medication regime that suppresses the bodies’ natural immune response to protect the integrity of the graft. There are many possible combinations of medication regimes, depending on the center’s protocol. • Induction Therapy • Initial potent prophylactic immunosuppression at the time of transplant to prevent hyper-acute or acute rejection • Agent of choice is dependent on recipients pre-existing medical conditions, donor characteristics, and the maintenance immunosuppressive regimen to be used • Lymphocyte count will drastically decrease. • Anti-fungal, anti-viral and anti-bacterial prophylaxis is required • Effect may last for months • Maintenance Immunosuppression • Medications will be taken for the life of the allograft • Patient compliance is critical to graft survival • Goal is to prevent rejection
Anastamosis of pancreas to Jejunum via a Roux-en-Y loop Mimics normal enteric drainage of pancreatic enzymes Difficult to diagnose rejection, can't measure secretion of enzymes Enteric Drainage (Panreaticojejunostomy)
Pancreas anastomosed to the recipients bladder Offers a direct method for assessing graft exocrine function (urine amylase decreases earlier than changes in blood glucose if graft is rejecting) Complications: Metabolic acidosis from bicarbonate loss into urine Ulceration/bleeding at duodenal segment Cystitis Volume imbalance due to excretion of ~ 2000 ml pancreatic fluid daily. Urinary Diversion(Pancreaticoduodencystostomy)
