HCC influence on patient survival after liver transplantation for HDV cirrhosis.

BACKGROUND/AIMS: The effect of hepatocellular cancer (HCC) in patients transplanted for hepatitis B and D virus (HB/DV) cirrhosis is not well studied. Our aim was to study the long-term survival outcomes of patients who underwent liver transplantation for HB/DV cirrhosis with and without HCC. METHODOLOGY: A total of 231 primary, adult, single- organ liver transplants were performed from 1990 to 2007. HB/DV was the cause of cirrhosis in 36 patients. Nine patients died during the first 3 postoperative months from surgical complications. The study group comprised the remaining 27 patients. The median follow-up was 1515 days. RESULTS: The mean patient survival was 3760 days (95% CI: 3013-4507). Six patients were diagnosed with HCC. The mean patient survival was 3011 days (95% CI: 2344-3679) and 4036 days (95% CI: 3002-5070) for recipients without and with HCC, respectively. For the same groups, the incidence of microbial infections was 61.9% and 33.3%, respectively (p=0.219). HCC has not recurred in any of the six patients. CONCLUSIONS: The mean long-term survival after liver transplantation for HB/DV and HCC surpassed 11 years. The superior survival of HCC patients is difficult to explain. The increased number (almost double) of microbial infections in the non- HCC population might be held accountable.

Pregnancy after liver transplantation. How safe? A retrospective case-series study in a large tertiary hospital.

OBJECTIVE: To study pregnancies achieved after liver transplantation in terms of obstetric complications, maternal, neonatal outcomes and post-pregnancy allograft function. METHODS: A retrospective study of prospectively collected data was conducted, enrolling women with a history of liver transplantation performed in the Transplantation Unit of our hospital that delivered in our department. Obstetric characteristics and antenatal complications were reviewed. Apgar score, admission to Neonatal Intensive Care Unit (NICU) and need for emergency intubation were analyzed. Outcomes of regular follow-up concerning all complications of allograft function observed after pregnancy were also studied. RESULTS: There were five cases of allograft recipients delivering their pregnancies during the study period. Mean maternal age was 32.2 ± 5 years. Interval from transplantation to delivery ranged from 40 to 219 months. Mean gestational week at delivery was 34.4 ± 2.5 weeks. Antenatal complications observed were pre-eclampsia (3 of 5 cases) and vaginal bleeding (1 of 5 cases). All preterm neonates were admitted to NICU, but no emergency intubation was demanded. One patient died a month after delivery, while three others were complicated by implant dysfunction up to 5 years after the delivery. CONCLUSION: Pregnancy in a liver transplant recipient is associated with complications for mother and infant.

Liver transplantation in Greek children: 15 years experience.

Liver transplantation (LT) is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation) due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclosporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV(1,2), 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation.The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers.

The natural history of vascular access for hemodialysis: a single center study of 2,422 patients.

BACKGROUND: Our objective is to provide provision of primary and secondary patency rates data and incidence of complications. Despite the publication of some review articles and small prospective trials about vascular accesses, controversy still exists regarding the choice of the outflow conduit and especially the choice of the fistula to be formed in secondary and tertiary access procedures. METHODS: This is a retrospective study of 2,422 consecutive patients who underwent 3,685 vascular access procedures in a tertiary care hospital, including radial-cephalic (RCAVF), brachial-cephalic (BCAVF), brachial-basilic (BBAVF), and prosthetic graft (PTFE) fistulas. Maximum follow-up period was 20 years. Actuarial patency rates were obtained by Kaplan-Meier analysis. RESULTS: The median primary patency (days) of the most common 1st choices for vascular access were 712 (95% CI: 606, 818), 1,009 (95% CI: 823, 1,195), and 384 (95% CI: 273, 945) days for RCAVF, BCAVF, and PTFE, respectively. The median secondary patency was 1809 days (95% CI: 1,692, 1,926) for the RCAVF. The median primary patency of BBAVF (2nd or 3rd choice for vascular access) was 1,582 days (95% CI: 415, 2,749). The cumulative incidence of clinically important complications for the patients who received a RCAVF, BCAVF, BBAVF, and u-PTFE was 0.25, 0.57, 0.33, and 0.61 per patient-year, respectively. CONCLUSION: We advocate maximal use of autogenous conduits, except probably the case of the older diabetic patient, in whom access at the antecubital fossa should be the first choice. BBAVF is an excellent fistula and should probably be constructed before prosthetic graft placement.
