An Introduction to Transplantation Lauren Walker, RN, BSN, CCRN Other Contributors: Lisa Dreyfuss, RN, BSN Hilary Poan, RN, BSN Goals and Objectives: *By the end of the lecture, students will have an understanding of: -The history of pediatric GI transplant -The qualification of being listed for transplant -Common diagnosis indicating a need for a liver or small bowel transplant -Signs and symptoms of liver and small bowel failure -Common preop/postop medications -Signs and symptoms of organ rejection -Lifetime management concerns after transplant History Transplants have been performed for over 50 years in United States: 1950s First Successful Kidney 1954 1960s First Successful Liver 1967 First Successful Heart 1968 First Successful Pancreas 1968 --UNOS http://www.unos.org/whoWeAre/history.asp Transplant History Then nothing until…. 1980s Why? CYCLOSPORIN (early generation Prograf) introduced 1983 First Successful Single Lung 1983 First Successful Double lung 1986 First Successful Intestine 1987 First Living donor liver 1989 --UNOS www.unos.org/whoWeAre/history.asp Organ Allocation: Getting Listed United Network for Organ Sharing (UNOS) maintains the transplant list. Transplant centers do a thorough evaluation of a candidate When a person is accepted for transplant by a transplant center, the center contacts UNOS and they are added to the list. Once listed, the transplant center contacts the candidate to let them know they are listed. Organ Allocation: Allocation When an organ is available, UNOS tracks and allocates the organ Organs are allocated by status. For Georgetown criteria is based on the Pediatric End Stage Liver Disease (PELD) Scoring System Status 1A – fulminant liver failure (no previous liver failure) Status 1B – liver failure necessitating the need for a blood transfusion within a 24 hour period for liver candidates Score from 1-40 based on labs including bilirubin, albumin, INR, age, growth failure. Pt. in need of SB get an automatic 23 points. Priority is as follows: Local Regional (DC is in region 2 , which also includes - Delaware, Maryland, New Jersey, Pennsylvania, West Virginia) National Who needs a Transplant? As of 06/6/11 111,502 people are waiting for transplants 16,487 waiting for a liver Mean waiting time kids < 1 yr 223 days Mean waiting time kids 1-5 yrs 262 days 221 waiting for an intestine Mean waiting time kids < 1 yr 358 days Mean waiting time kids 1-5 yrs 425 days National pediatric (up to 17yrs) survival from 1 to 5 years: over 83% Liver Transplant Common indications for liver transplant seen on our unit include: Biliary Atresia Alagille’s Syndrome Hepatitis B Hepatoblastoma Hemochromatosis Signs of Liver Failure Increased Liver Function Tests (ALT, AST, Alk phos, bilirubin (direct and indirect) Jaundice Bleeding Ascites Spleno/Hepatomegaly Glucose Intolerance Increased Infection Malnutrition (Vit. A, D, E, K) Dark Urine Puritis Osteoporosis/Fractures Liver Transplant A liver transplant can be done in 3 ways: 1) Cadaver 2) Living-Related Donor (generally left lobe) 3) Cadaver Split Liver Intestinal Failure: Definition The inability of the gastrointestinal system to maintain fluid, electrolyte, and nutritional balance of the body Condition requires supplementation from sources outside of the GI tract History of Intestinal Transplant 1988 1st successful transplant. Why so late? Large organ Lots of lymphoid tissue in intestinal system = immunity Bacterial flora Outcomes have improved with new medications (Prograf) Currently 23 centers have patients listed for intestinal transplant. Pittsburgh and GUH are the largest. National pediatric (up to 17yrs) survival rate from 1 to 5 yrs: over 71.5% (63.8% for kids under a yr) Diagnosis leading to a SB Transplant Structural: NEC, Gastroschisis, malformation/volvulus, trauma, atresia, tumor Functional: Pseudo-obstruction, Megacystis, Microcolon, Intestinal Hypoperistalsis, Hirschsrpung’s disease Indications in Children for Small Bowel Transplant Motility Other Tumor 1% Aganglionosis/ 2% Hirshsprung's 7% Re-Tx 7% Other 2% Volvulus 18% PseudoObstruction 9% Malabsorption Other 4% Microvillus Inclusion Short Gut 6% Other 4% Gastroschisis 21% Intestinal Atresia 7% Necrotizing Enterocolitis 12% Management of Intestinal Failure Gut Rehabilitation STEP procedure Intestinal stretching Time (as patient grows, gut grows and absorbs more) Lifetime TPN – Will lead to liver failure Intestinal Transplant Signs of Intestinal Failure Diarrhea Constipation Emesis Fluid Imbalance and signs and symptoms of fluid imbalance Electrolyte Imbalance and signs and symptoms of electrolyte imbalance Malnutrition and signs and symptoms of malnutrition Failure to Thrive (FTT) Skin breakdown r/t diarrhea Liver failure and its signs and symptoms if TPN cholestatis occurs Criteria for transplantation Can only be listed for Intestinal transplant with: Loss of access Irretractable dehydration Multiple septic infections Liver failure r/t TPN Types of Intestinal Transplant Isolated Intestine Liver/Bowel Multivisceral Liver, intestine, pancreas, stomach The transplanted organ Must be at least 70% size of recipient Minimal downtime/ischemic time (intestine 10 hours or less, liver 24 hours) minimal pressor support before harvest ABO compatibility Negative crossmatch (PRA) Pre Transplant Care Issues TPN Dependent Infection Dehydration Malnutrition GI bleed r/t portal hypertension Waiting Time Socialization Pre-transplant Medications Vitamins (ADEK) Calcitriol Nystatin Iron Post-Transplant Medications Immune Suppression: Prograf, Prednisolone, Rapamune, Cellcept, Baxiliximab Other Common Meds: Prevacid, Imodium, Lomotil, Reglan, Norvasc, Propranolol Post Transplant Issues Immunosuppression Rejection Infection Education Adherence Support Rejection The immune system protects the body from anything that is not self. Because a transplant is foreign to the body, without intervention, the immune system will attempt to destroy it. Goal of immunosuppressants is to inhibit immunological response and therefore prevent rejection. Early signs and Symptoms of rejection General Fever greater than 38°C Tachycardia High or low immunosuppressant levels Lethargy/irritability Abdominal pain or distention Liver Rejection Liver Increased liver function tests Nausea and/or vomiting Dark urine Jaundice Itchy skin Intestine Rejection Intestine Increased stools and/or ostomy output Dehydration Increasing WBC Falling hemoglobin, albumin, or iron saturation Weight loss Bloody stools/ostomy output Pale, black, or bleeding stoma Output with clots or chunks of tissue Sepsis Rejection Monitoring LFTs for Liver Output and stoma for SB, appearance during scopes ONLY SURE WAY TO KNOW is through a biopsy Rejection is treated with high dose Steroids and Thymoglobulin Major Complication: Infection Most common complication because of immunosuppression HAND WASHING Avoid sick contacts No raw foods, no live vaccines, no cleaning up after pets Prophylactic Meds Surveillance labs for EBV, CMV, Adenovirus Life after Transplant Scope twice a week for the first month Once a week for the next two months Annual scope Blood draws twice a week for the first 3 months Labs once a week until labs are stable Labs at least once every three months Lifetime of immunosuppressants Rejection can happen at any time Lifetime Management Issues Quality of Life Lifetime medication regime Lifetime laboratory surveillance of immunosuppression levels Lifetime surveillance for rejection Annual visits to transplant center Resources Unos: http://unos.org/ Georgetown University Hospital Transplant Center for Children http://www.georgetownuniversityhospit al.org/body.cfm?id=555650
