Meta-analysis and systematic review of the effect of the donor and recipient CYP3A5 6986A>G genotype on tacrolimus dose requirements in liver tran…
2013
Objective A meta-analysis was carried out of publishedstudies on the effect of the CYP3A5 6986A>Gpolymorphism in liver donors and transplant recipientson tacrolimus pharmacokinetics.Methods Cohort studies that evaluated the relationshipbetween the CYP3A5 polymorphism in liver donors andtransplant recipients and tacrolimus, trough bloodconcentration normalized for the daily dose (C) perkilogram body weight (D) (C/D, ng/ml/mg/kg/day) up to1 year after transplantation, were included. Data were notrestricted by patient age or the language or journal ofpublication. A literature search was conducted using theCochrane Library, MEDLINE, EMBASE, and grey literature,and articles published up to 24 Ap…
“Preemptive” Live Donor Liver Transplantation for Fibrolamellar Hepatocellular Carcinoma: A Case Report
2008
Fibrolamellar (FL) hepatocellular carcinoma (HCC) is a distinctive form of primary HCC that occurs principally in children and young adults. Although liver transplantation is not contraindicated for FL-HCC, noncirrhotic patients with large HCC tumors (including FL-HCCs) are not prioritized. Although hepatic resection is considered to be the primary treatment for FL-HCC, living donor liver transplantation is evolving into a potentially better alternative. Herein we have reported successful "preemptive" living donor liver transplantation for presumed recurrence of FL-HCC after an extended right hepatectomy with resection and synthetic graft replacement of the inferior vena cava.
Hepatic Hilar and Sectorial Vascular and Biliary Anatomy in Right Graft Adult Live Liver Donor Transplantation
2008
Abstract Introduction The aim of this study was to analyze vascular and biliary variants at the hilar and sectorial level in right graft adult living donor liver transplantation. Methods From January 2003 to June 2007, 139 consecutive live liver donors underwent three-dimensional computed tomography (3-D CT) reconstructions and virtual 3-D liver partitioning. We evaluated the portal (PV), arterial (HA), and biliary (BD) anatomy. Results The hilar and sectorial biliary/vascular anatomy was predominantly normal (70%–85% and 67%–78%, respectively). BD and HA showed an equal incidence (30%) of hilar anomalies. BD and PV had a nearly identical incidence of sectorial abnormalities (64.7% and 66.2…
Obesity reduces uterine receptivity: clinical experience from 9,587 first cycles of ovum donation with normal weight donors
2013
Objective To analyze the reproductive outcome of recipients of donated ova according to their body mass index (BMI). Design Twelve-year retrospective cohort analysis. Setting Fertility clinics. Patient(s) 9,587 first cycles of ovum donation with ova from normoweight donors. Intervention(s) Recipients divided according to their BMI to analyze IVF laboratory and outcome parameters: lean with BMI 2 (n = 1,458; 15.2%); normoweight with BMI 20–24.9 kg/m 2 (n = 5,706; 59.5%), overweight with BMI 25–29.9 kg/m 2 (n = 1,770; 18.5%), and obese with BMI ≥30 kg/m 2 (n = 653; 6.8%). Main Outcome Measure(s) Implantation, biochemical and clinical pregnancy, miscarriage, and live-birth rates. Result(s) In …
Infections of the Central Nervous System after Unrelated Donor Umbilical Cord Blood Transplantation or Human Leukocyte Antigen–Matched Sibling Transp…
2016
We analyzed the incidence, clinical characteristics, prognostic factors, and outcome of central nervous system (CNS) infections in consecutive patients with receiving umbilical cord blood transplantation (UCBT) (n = 343) or HLA-matched sibling donor stem cell transplantation (MST) (n = 366). Thirty-four CNS infections were documented at a median time of 116 days after transplantation (range, 7 to 1161). The cumulative incidence (CI) risk of developing a CNS infection was .6% at day +30, 2.3% at day +90, and 4.9% at 5 years. The 5-year CI of CNS infection was 8.2% after UCBT and 1.7% after MST (P .001). The causative micro-organisms of CNS infections were fungi (35%), virus (32%), Toxoplasm…
Improved short-term outcomes of kidney transplants in controlled donation after the circulatory determination of death with the use of normothermic r…
2021
Normothermic Regional Perfusion (NRP) allows the in situ perfusion of organs with oxygenated blood in donation after the circulatory determination of death (DCDD). We aimed at evaluating the impact of NRP on the short-term outcomes of kidney transplants in controlled DCDD (cDCDD). This is a multicenter, nationwide, retrospective study comparing cDCDD kidneys obtained with NRP versus the standard rapid recovery (RR) technique. During 2012-2018, 2,302 cDCDD adult kidney transplants were performed in Spain using NRP (n=865) or RR (n=1,437). The study groups differed in donor and recipient age, warm and cold ischemic time and use of ex situ machine perfusion. Transplants in the NRP group were m…
A New Systematic Classification of Peripheral Anatomy of the Right Hepatic Duct: Experience From Adult Live Liver Donor Transplantation
2008
Abstract Objective The peripheral intrahepatic biliary anatomy, especially at the sectorial level on the right side, has not been adequately described. The purpose of our study was to systematically describe this complex anatomy in clinically applicable fashion. Patients and Methods We analyzed three-dimensional computed tomography (CT) imaging reconstructions of 139 potential living liver donors evaluated at our institution between January 2003 and June 2007. Results Eighty-nine (64%) donors had a normal right bile duct sectorial anatomy. In the other 50/139 (36%) cases, we observed abnormal sectorial branching patterns, with 45/50 abnormalities as trifurcations, whereas the remaining ones…
Allogeneic stem cell transplantation for renal cell carcinoma
2011
Allogeneic hematopoietic stem cell transplantation from a compatible donor has been utilized as adoptive immunotherapy in metastatic, cytokine-refractory renal cell carcinoma (RCC). Since the year 2000, several investigators have established that RCC is susceptible to a graft-versus-tumor effect: they reported that patients with renal cancer may have partial or complete disease responses, in the 20-40% range, after allogeneic transplantation following a reduced-intensity regimen. However, transplant-related mortality is still high in the 10-20% range, and responses are rarely durable. Experimental evidence suggests that donor-derived T cells and natural killer cells are the main mediators o…
Ethical aspects of Fecal Microbiota Transplantation (FMT).
2015
The importance of human microbiota in preserving human organism healthy is nowadays well acknowledged. The alteration of the microbiota can be the consequence of a persistent use of antibiotics or immunosuppressive medications or abdominal irradiation or surgery, wrong diet, or can be caused by surgery or anatomical condition. These alterations can cause many infections and diseases that today can be treated with Fecal Microbiota Transplantation (FMT), also called Bacteriotherapy, that is the administration of a fecal solution from a donor into the intestinal tract of a recipient. Although to date, FMT appears to be safe and without serious adverse effects, there are some ethical issues tha…
Screening sierologico per Leishmania infantum su donatori di sangue e HIV+ asintomatici residenti in area endemica [Serological screening for Leishma…
2008
Visceral leishmaniasis (VL) is endemic in Sicily (48 new cases in 2004, of which nine were in Agrigento). In southern Europe between 25-70 per cent of adult VL cases are related to HIV infection. The HIV cases have a high risk (1.5-9%) of developing VL either as a new infection or as the revival of a latent infection. We therefore carried out serologic screening to detect antibodies against L. infantum by IFAT in 1449 blood donors in Agrigento and the surrounding area (May-December 2005) and in 120 HIV+ in western Sicily, all of whom were asymptomatic and had no history of VL. L. DNA was assessed by nested PCR in blood samples of some seropositive donors. Of the 1449 blood donors, 11 (0.75%…
