    Full Text Available The present study was designed to investigate hemochromatosis patients' suitability as blood donors as well as their perceptions and experience with the current public donation system. Participants were gathered from a list of current hemochromatosis patients (n=120 and members of the Canadian Hemochromatosis Society (n=1000. Of the 1120 surveys mailed out to these groups, 801 surveys were returned completed. The sample respondents had a mean age of 57.44 years (SD=12.73; range 19 to 87 years, and 57% were men. It was found that 20% (160 of the respondents have donated blood since their diagnosis; however, only 12% of the respondents indicated that they use voluntary blood donation as a means of maintaining their iron levels. Forty per cent of the respondents indicated that they had been refused from voluntary donation. Despite the fact that in May 2001 the Canadian Blood Services, in collaboration with the Canadian Hemochromatosis Society, began a promotion campaign to encourage hemochromatosis patients to become voluntary blood donors, the present study found that 15% of the respondents reported having been refused from the voluntary blood donation service due to the diagnosis of hemochromatosis. With respect to quality of life, it was found that individuals who donate blood were generally healthier with respect to physical functioning and bodily pain, however, these findings may indicate that hemochromatosis patients who are healthier are better able to donate at public blood banks, rather than that voluntary blood donation has an effect on the donors' physical functioning over phlebotomy clinic users. These study findings suggest that although there may be other medical factors limiting individuals from donating, hemochromatosis patients are interested in being voluntary blood donors and this potential resource is currently under-used.

    Although nephrectomy by open surgery is the most used technique for the extraction of kidney transplants in the living donor, nephrectomy under laparaoscopy is increasingly practiced. Laparoscopic nephrectomy is less invasive and performed under videoscopy control, after insufflation of the peritoneal cavity. Three to four incisions are done in order to enter the surgical instruments. The kidney is extracted through a horizontal sus-pubic incision. The exposition is either exclusively transperitoneal, retroperitoneal or hand assisted. The advantages of laparoscopy are esthetical, financial due to a shorter hospitalisation and a quicker recovery, as well a confort for the donor. The disadvantages are a longer warm ischemia time and possibly a higher risk of delayed graft function. Randomised studies having compared laparoscopy and open surgery in the living donor have not find any significant difference regarding the per- and perioperative in the complications.

    We argue that the dead donor rule, which states that multiple vital organs should only be taken from dead patients, is justified neither in principle nor in practice. We use a thought experiment and a guiding assumption in the literature about the justification of moral principles to undermine the theoretical justification for the rule. We then offer two real world analogues to this thought experiment, voluntary active euthanasia and capital punishment, and argue that the moral permissibility of terminating any patient through the removal of vital organs cannot turn on whether or not the practice violates the dead donor rule. Next, we consider practical justifications for the dead donor rule. Specifically, we consider whether there are compelling reasons to promulgate the rule even though its corresponding moral principle is not theoretically justified. We argue that there are no such reasons. In fact, we argue that promulgating the rule may actually decrease public trust in organ procurement procedures and medical institutions generally - even in states that do not permit capital punishment or voluntary active euthanasia. Finally, we examine our case against the dead donor rule in the light of common arguments for it. We find that these arguments are often misplaced - they do not support the dead donor rule. Instead, they support the quite different rule that patients should not be killed for their vital organs.

    Full Text Available Introduction: Partial phenotyping of voluntary blood donors has vital role in transfusion practice, population genetic study and in resolving legal issues.The Rh blood group is one of the most complex and highly immunogenic blood group known in humans. The Kell system, discovered in 1946, is the third most potent system at triggering hemolytic transfusion reactions and consists of 25 highly immunogenic antigens. Knowledge of Rh & Kell phenotypes in given population is relevant for better planning and management of blood bank; the main goal is to find compatible blood for patients needing multiple blood transfusions. The aim of this study was to evaluate the frequency of Rh & Kell phenotype of voluntary donors in Gujarat state. Materials and Methods: The present study was conducted by taking 5670 samples from random voluntary blood donors coming in blood donation camp. Written consent was taken for donor phenotyping. The antigen typing of donors was performed by Qwalys-3(manufacturer: Diagast by using electromagnetic technology on Duolys plates. Results: Out of 5670 donors, the most common Rh antigen observed in the study population was e (99.07% followed by D (95.40%, C (88.77%, c (55.89% and E (17.88%. The frequency of the Kell antigen (K was 1.78 %. Discussion: The antigen frequencies among blood donors from Gujarat were compared with those published for other Indian populations.

    Full Text Available OBJECTIVE: To present the initial experience of videolaparoscopic nephrectomy in live renal donor. MATERIALS AND METHODS: In the period from April 2000 to August 2003, 50 left nephrectomies in live donor were performed by videolaparoscopy for transplantation. Twenty-eight patients were male (56% and 22 female (44%. Mean age was 37.2 years, and the mean body mass index (BMI was 27.1 kg/m². RESULTS: Mean surgical time was 179.5 minutes, and warm ischemia time of the graft was 3.79 minutes. The mean estimated bleeding was 141 mL. There was no need of blood transfusion or conversion to open surgery. In 42 cases (84%, the vascular portion of the graft was considered good by the recipient's surgical team and in all cases, the ureter was considered of proper size, though in one of them (2% its vascularization was considered improper. The transplanted kidneys produced urine still in the surgical room in 46 of the 50 transplantations considered. In only 2 cases opioid was required for analgesia. In average, 3.1 doses of dipyrone were used for each patient during hospital stay, and hospital discharge occurred, in average, after 3.2 days post-operatively. Two patients required re-operations and one of them evolved to death. CONCLUSIONS: The laparoscopic nephrectomy in live donor for renal transplantation is an alternative to conventional open surgery. In relation to the graft, no alteration, either anatomic or functional, was detected. Though there is already a large documentation in the international literature regarding this procedure, in our setting a prospective randomized study with the usual surgical study is still necessary in order to prove the advantages and disadvantages of the method.

    The Rh system is the major blood group system besides ABO system. Even after proper blood grouping and cross matching there is a possibility of alloimmunization and antibody production in the recipients against the Rh or minor blood group antigens like Kell, MNSs, Duffy etc. Keeping in view the heavy financial burden of complete phenotyping of blood; the determination of only Rh phenotypes can play a major role in preventing alloimmunization and adverse events in multitransfusion cases. To determine the proportion of Rh phenotypes in voluntary blood donors with a view to generate blood bank data for constitution of panel of blood donors for multipurpose utilities. Identification of Rhesus factors (Rh) was done by the antigen antibody agglutination test by the test tube method on 10,133 healthy voluntary donors. The phenotypic frequencies of Rh blood groups in the studied population were D-92.25%, C-87.55%, E-26.55%, c-51.06% and e-98.42%. Thus 'e' was the most common and E was the least common of all the Rh types. Phenotypically DCCee group was the most common phenotype and dccee was least common type. Determination of Rh phenotypes can play a major role in preventing alloimmunization and avoiding adverse events in multitransfusion cases.

  11. Renal Transplantation from Elderly Living Donors

    Full Text Available Acceptance of elderly living kidney donors remains controversial due to the higher incidence of comorbidity and greater risk of postoperative complications. This is a review of publications in the English language between 2000 and 2013 about renal transplantation from elderly living donors to determine trends and effects of donation, and the outcomes of such transplantation. The last decade witnessed a 50% increase in living kidney donor transplants, with a disproportionate increase in donors >60 years. There is no accelerated loss of kidney function following donation, and the incidence of established renal failure (ERF and hypertension among donors is similar to that of the general population. The overall incidence of ERF in living donors is about 0.134 per 1000 years. Elderly donors require rigorous assessment and should have a predicted glomerular filtration rate of at least 37.5 mL/min/1.73 m2 at the age of 80. Though elderly donors had lower glomerular filtration rate before donation, proportionate decline after donation was similar in both young and elderly groups. The risks of delayed graft function, acute rejection, and graft failure in transplants from living donors >65 years are significantly higher than transplants from younger donors. A multicentred, long-term, and prospective database addressing the outcomes of kidneys from elderly living donors is recommended.

    The worldwide shortage of adequate donor organs implies that living donor liver transplantation represents a valuable alternative to cadaveric transplantation. In addition to the complex surgical procedure the correct identification of eligible donors and recipients plays a decisive role in living donor liver transplantation. Donor safety must be of ultimate priority and overrules all other aspects involved. In contrast to the slightly receding numbers in Europe and North America, in recent years Asian programs have enjoyed constantly increasing living donor activity. The experience of the past 15 years has clearly demonstrated that technical challenges of both bile duct anastomosis and venous outflow of the graft significantly influence postoperative outcome. While short-term in-hospital morbidity remains increased compared to cadaveric transplantation, long-term survival of both graft and patient are comparable or even better than in deceased donor transplantation. Especially for patients expecting long waiting times under the MELD allocation system, living donor liver transplantation offers an excellent therapeutic alternative. Expanding the so-called "Milan criteria" for HCC patients with the option for living donor liver transplantation is currently being controversially debated.

    The ethical debate surrounding transplant practices questions our societies. International recommendations set out numerous precautions which must be taken to ensure that donors act with their free will. While in most countries, including France, organ donation is a voluntary and non-commercial act, a black market exists in the world resulting in the trafficking of organs and tragic transplant tourism.

    Living donor liver transplantation (LDLT) has gone through its formative years and established as a legitimate treatment when a deceased donor liver graft is not timely or simply not available at all. Nevertheless,LDLT is characterized by its technical complexity and ethical controversy. These are the consequences of a single organ having to serve two subjects, the donor and the recipient, instantaneously. The transplant community has a common ground on assuring donor safety while achieving predictable recipient success. With this background, a reflection of the development of LDLT may be appropriate to direct future research and patient- care efforts on this life-saving treatment alternative.

    The disparity between kidney transplant candidates and donors necessitates innovations to increase organ availability. Transporting kidneys allows for living donors and recipients to undergo surgery with a familiar transplant team, city, friends, and family. The effect of shipping kidneys and prolonged cold ischemia time (CIT) with living donor transplantation outcomes is not clearly known. This retrospective matched (age, gender, race, and year of procedure) cohort study compared allograft outcomes for shipped live donor kidney transplants and nonshipped living donor kidney transplants. Fifty-seven shipped live donor kidneys were transplanted from 31 institutions in 26 cities. The mean shipping distance was 1634 miles (range 123-2811) with mean CIT of 12.1 ± 2.8 h. The incidence of delayed graft function in the shipped cohort was 1.8% (1/57) compared to 0% (0/57) in the nonshipped cohort. The 1-year allograft survival was 98% in both cohorts. There were no significant differences between the mean serum creatinine values or the rates of serum creatinine decline in the immediate postoperative period even after adjusted for gender and differences in recipient and donor BMI. Despite prolonged CITs, outcomes for shipped live donor kidney transplants were similar when compared to matched nonshipped living donor kidney transplants.

    An integrated strategy for blood safety is required for the provision of safe and adequate blood. Recruiting a sufficient number of safe blood donors is an emerging challenge. The shortage of blood in India is due to an increase in the demand, with fewer voluntary blood donors. A study on the knowledge, attitude and the practice of donors may prove to be useful in the successful implementation of the blood donation programme. Our aim was to find the level of the knowledge, attitude and practice of blood donation among voluntary blood donors. A structured questionnaire was given to 530 voluntary blood donors to assess their knowledge, attitude and practice with respect to blood donations. The statistical analyses were done by using the SPSS software. The associations between the demographic factors were analysed by using the Chi square test. Among the 530 donors, 436 (93%) were males and 36 (7%) were female donors. 273 (51.2%) donors knew about the interval of the donation and 421 (79.4%) donors knew about the age limit for the donation. 305 (57%) donors felt that creating an opportunity for the donation was an important factor for motivating the blood donation and 292 (55%) donors felt that the fear of pain was the main reason for the hesitation of the donors in coming forward to donate blood. A majority of the donors were willing to be regular donors. The donors showed positive effects like a sense of satisfaction after the donation. Creating an opportunity for blood donation by conducting many blood donation camps may increase the voluntary blood donations.

    Renal transplantation from a living donor is now considered the best treatment for chronic renal failure. We reviewed the operative complications in 38 living related donor nephrectomies performed at our institution over the past 14 years. The mean age of our donors was 30 years old with age range between 18 and 58 years old and female predominance (55.2%). These swabs were realized by a posterolateral lumbar lombotomy with resection of the 11 third. The left kidney was removed in 34 donors (90%), surgical complications were noted in 39.4% of the cases: one case of wound of inferior vena cava (2.6%), one case of release of the renal artery clamp (2.6%), four cases of pleural grap (10.5%), one case of pneumothorax (2.6%), one case of pleurisy (2.6%), three cases of urinary infection (7.8%), three cases of parietal infection (7.8%) and one case of patient pain at the level of the wound (2.6%). There were no mortalities. We conclude that the morbidity of living donor nephrectomy is negligible compared with the advantages for the recipient.

Living donation offers a solution to the growing gap between the need for liver transplants and the limited availability of deceased donor organs. With a multidisciplinary team focused on donor safety and experienced surgeons capable of performing complex resection/reconstruction procedures, donor morbidity is low and recipient outcomes are comparable with results of deceased donor transplantation.

    Full Text Available Background : Voluntary non-remunerated repeat blood donors are perceived to be safer than the first time blood donors. This study was planned for follow-up of previous hepatitis C virus (HCV test results of anti-HCV enzyme-linked immunosorbent assay (ELISA reactive repeat blood donors. The aim was to suggest a protocol for re-entry of the blood donors who are confirmed HCV negative by nucleic acid test (NAT and recombinant immunoblot assay (RIBA. A group of repeat voluntary donors were followed retrospectively who became reactive on a cross sectional study and showed HCV reactivity while donating blood regularly. Material and Methods: A total of 51,023 voluntary non remunerated blood donors were screened for anti-HCV ELISA routinely. If anybody showed positivity, they were tested by two ELISA kits (screening and confirmatory and then confirmed infection status by NAT and or RIBA. The previous HCV test results of repeat donors reactive by anti-HCV ELISA were looked back from the records. Data of donors who were repeat reactive with single ELISA kit (in the present study were analyzed separately from those reactive with two ELISA kits (in the present study. Results: In this study, 140 (0.27% donors who were reactive by anti HCV ELISA were included. Out of them, 35 were repeat voluntary donors and 16 (11.43% were reactive with single ELISA kit. All 16 donors were reactive by single ELISA kit occasionally in previous donations. Their present ELISA positive donations were negative for HCV NAT and RIBA. A total of 19 (13.57% donors were reactive with two ELISA kits. In their previous donations, the donors who were reactive even once with two ELISA kits were consistently reactive by the same two ELISA kits in their next donations also. Conclusion: Donor sample reactive by only single ELISA kit may not be considered as infectious for disposal as they were negative by NAT and or RIBA. One time ELISA positivity was found probably due to ELISA kit

    Living donor hepatectomy (LDH) is high risk to a healthy donor and remains controversial. Living donor nephrectomy (LDN), conversely, is a common practice. The objective is to examine the outcomes of LDH and compare this risk profile to LDN. The Nationwide Inpatient Sample was queried for hepatectomies and nephrectomies from 1998 to 2011. LDH or LDN were identified by donor ICD-9 codes. Outcomes included in-hospital mortality and complications. Bivariate analysis compared nondonor hepatectomy or nondonor nephrectomy (NDN). Multivariate analyses adjusted for baseline organ disease, malignancy, or benign lesions. There were 430 LDH and 9211 nondonor hepatectomy. In-hospital mortality was 0 and 6 per cent, respectively (P < 0.001); complications 4 and 33 per cent (P < 0.001). LDH had fewer complications [odds ratio (OR) 0.15 (0.08-0.26)]. There were 15,631 LDN and 117,966 NDN. Mortality rates were 0.8 per cent LDN and 1.8 per cent NDN (P < 0.001). Complications were 1 and 21 per cent (P < 0.001). LDN had fewer complications [OR 0.06 (0.05-0.08)] and better survival [OR 0.32 (0.18-0.58)]. Complication rates were higher in LDH than LDN (4% vs 1%, P < 0.001), but survival was similar (0% vs 0.8% mortality, P = 0.06). In conclusion, morbidity and mortality rates of LDH are significantly lower than hepatectomy for other disease. This study suggests that the risk profile of LDH is comparable with the widely accepted LDN.

    Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Three hundred and fifty donors and 353 recipients in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) receiving transplants between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV and SLV), Model for End-Stage Liver Disease (MELD) score (in recipients), the remnant and graft size, remnant-to-donor and graft-to-recipient weight ratios (RDWR and GRWR), remnant/TLV, and graft/SLV. Among donors, 3-month absolute growth was 676 ± 251 g (mean ± SD), and percentage reconstitution was 80% ± 13%. Among recipients, GRWR was 1.3% ± 0.4% (8 Graft weight was 60% ± 13% of SLV. Three-month absolute growth was 549 ± 267 g, and percentage reconstitution was 93% ± 18%. Predictors of greater 3-month liver volume included larger patient size (donors and recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (P = 0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR = 4.50, P = 0.001) but not by GRWR or graft fraction (P > 0.90 for each). Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, and this confirmed previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3-month volumes. Importantly, donor liver volume is a critical predictor

    Living donor kidney transplantation has been increasing since 2008. Living donors represent a significant potential for organ transplants, in a context where the needs outstrip the availability of organs from deceased donors. However, patients are still poorly informed regarding the conditions in which these transplants are possible. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Donor safety is of paramount importance in living donor transplantation. Yet, living donor deaths occur. We believe that problems exist in our system of live donor transplantation that can be summarized in a series of simple statements: (1) Donor mortality can never be completely eliminated; (2) Live donor risk has not been mitigated so that it is as low as possible; (3) After a donor death, systematic reviews are not routinely performed to identify correctable causes; (4) The lessons learned from any donor death are not adequately communicated to other programs and (5) The administrative mechanisms and resources are not universally available at all transplant centers to implement lessons learned. To rectify these problems, we propose the following: (1) A national living donor death task force be established with the purpose of performing systematic reviews of any donor death. (2) Findings of these reviews be disseminated to all institutions performing live donor transplants on a secure, password-protected website. (3) A no-fault donor death indemnity fund be established to provide a financial imperative for institutions to cooperate with this external peer-review. These measures will serve the best interests of the involved institutions, the transplant community, and most importantly, the patients and their families.

    Being an organ donor may affect one's ability to obtain life, disability and health insurance. We conducted a systematic review to determine if insurability is affected by living organ donation, and if concern about insurability affects donor decision making. We searched MEDLINE, EMBASE, SCI, EconLit and Cochrane databases for articles in any language, and reviewed reference lists from 1966 until June 2006. All studies discussing the insurability of living organ donors or its impact on donor decision making were included. Data were independently abstracted by two authors, and the methodological quality appraised. Twenty-three studies, from 1972 to 2006, provided data on 2067 living organ donors, 385 potential donors and 239 responses from insurance companies. Almost all companies would provide life and health insurance to living organ donors, usually with no higher premiums. However, concern about insurability was still expressed by 2%-14% of living organ donors in follow-up studies, and 3%-11% of donors actually encountered difficulties with their insurance. In one study, donors whose insurance premiums increased were less likely to reaffirm their decision to donate. Based on available evidence, some living organ donors had difficulties with insurance despite companies reporting otherwise. If better understood, this potential barrier to donation could be corrected through fair health and underwriting policies.

    Lack of willingness to pledge eyes among the general population is the main cause for the shortage of cornea tissue in China. A few studies have implied that general-population adults with specific demographics showed more willingness to donate their eyes. In this study, we analyzed the demographic characteristics of 918 voluntary donors registered in Beijing Tongren Hospital Eye Bank in the past 10 years for possible predictors that might help us to identify potential donors in Beijing and increase the donation rate. All copies of voluntary eye donation application forms filled by the registrants from 2007 to 2016 were collected. Basic demographics listed in the application form were extracted for analysis. Demographics were described as proportions and compared by means of a χ(2) test. Besides that, donor counts and proportions of combining 2 demographics from the 4 main demographics were described and compared. Voluntary donors greater than 50 years of age (n = 477, 53.0%) predominated the proportions. Regarding education level and occupation, donors with tertiary education (n = 484, 57.4%) were more numerous than donors with primary and secondary education (n = 355, 42.1%); office clerks, workers, and government officers were more willing to pledge eyes than were donors engaged in other occupations. In addition, donors of the Han race (n = 856, 94.9%) made up the majority and mainly were distributed in 5 central administrative districts of Beijing (n = 629, 77.5%). The present study suggests that older women (>50 years of age), living in a central district, with higher education level and engaged in white-collar work, were possible predictors for potential donors.

    The purpose of this phenomenological study was to examine the meaning of being a live liver donor. Six people between ages 27 and 53 years participated. A qualitative, in-depth, semistructured interview format was used to explore donors' thoughts and feelings about being an organ donor. Five themes were identified: (1) no turning back--how do I live without you? (2) roller coaster marathon, (3) donor network, (4) the scar, and (5) reflections--time to think. At the center of the experience was the donor's commitment to the recipient. Once donors began the process, they were determined to see it through. The process was complex, and donors received various levels of support from family, friends, health care professionals, and others. After donation, as donors recovered and were able to resume their usual daily responsibilities, they reflected on the impact of the experience and how it changed their view of life.

    Blood donation results in a substantial iron loss and subsequent mobilization from body stores. Chronic iron deficiency is a well-recognized complication of regular blood donation. The present study conducted to compare the level of serum ferritin, serum iron, total iron binding capacity (TIBC) and percentage transferrin saturation in different ABO and Rhesus type blood groups among the voluntary blood donors of Bangladesh. The present prospective study included 100 healthy voluntary donors attending at Department of Blood Transfusion, Dhaka Medical College, Dhaka between the periods of July 2013 to Jun 2014. From each donor 10mL venous blood sample was taken and divided into heparinized and non-heparinized tubes for determination of hemoglobin (Hb), hematocrit (Hct), serum iron (SI), total iron binding capacity (TIBC) and serum ferritin by standard laboratory methods. Percentage of transferrin saturation (TS) calculated from serum iron and TIBC. Data were analyzed with SPSS (version 16) software and comparisons between groups were made using student's t-test and one way ANOVA. In the present study mean±SD of age of the respondents was 27.2±6.5 years with a range of 18 to 49 years and 81.0% were male and 19.0% were female. Among the donors 18.0% had blood group A, 35.0% had blood group B, 14.0% had blood group AB and 33.0% had blood group O. Among the donors 91.0% had rhesus positive and 9.0% had rhesus negative. Donors with blood group O had lowest haemoglobin, serum iron and transferring saturation levels. Donors with blood group A had highest TIBC level. Donors with blood group B had lowest serum ferritin level. An independent samples 't' test showed statistically significant difference in serum ferritin and percentage transferrin saturation between blood group AB and blood group O and in percentage transferrin saturation between blood group B and blood group O. One way ANOVA showed that there is no significant difference in haemoglobin, serum iron, serum

    BACKGROUND: Varied vascular and biliary anatomies are common in the liver. Living donor hepatectomy requires precise recognition of the hilar anatomy. This study was undertaken to study donor vascular and biliary tract variations, surgical approaches and implications in living liver transplant patients. METHODS: Two hundred living donor liver transplantations were performed at our institution between 2004 and 2009. All donors were evaluated by volumetric computerized tomography (CT), CT angiography and magnetic resonance cholangiography in the preoperative period. Intraoperative ultrasonography and cholangiography were carried out. Arterial, portal and biliary anatomies were classified according to the Michels, Cheng and Huang criteria. RESULTS: Classical hepatic arterial anatomy was observed in 129 (64.5%) of the 200 donors. Fifteen percent of the donors had variation in the portal vein. Normal biliary anatomy was found in 126 (63%) donors, and biliary tract variation in 70% of donors with portal vein variations. In recipients with single duct biliary anastomosis, 16 (14.4%) developed biliary leak, and 9 (8.1%) developed biliary stricture; however more than one biliary anastomosis increased recipient biliary complications. Donor vascular variations did not increase recipient vascular complications. Variant anatomy was not associated with an increase in donor morbidity. CONCLUSIONS: Living donor liver transplantation provides information about variant hilar anatomy. The success of the procedure depends on a careful approach to anatomical variations. When the deceased donor supply is inadequate, living donor transplantation is a life-saving alternative and is safe for the donor and recipient, even if the donor has variant hilar anatomy.

    Liver transplants, originally obtained from deceased donors, can now be harvested from living donors as well. This technique, called living-donor liver transplantation (LDLT), provides an effective alternative means of liver transplantation and is a method of expanding the donor pool in light of the demand and supply imbalance for organ transplants. Imaging plays an important role in LDLT programmes by providing robust evaluation of potential donors to ensure that only anatomically suitable donors with no significant co-existing pathology are selected and that crucial information that allows detailed preoperative planning is available. Imaging evaluation helps to improve the outcome of LDLT for both donors and recipients, by improving the chances of graft survival and reducing the postoperative complication rate. In this review, we describe the history of LDLT and discuss in detail the application of imaging in donor assessment with emphasis on use of modern computed tomography (CT) and magnetic resonance imaging (MRI) techniques.

    An increase in waiting time for a cadaveric organs and a better graft-function, graft- and patient-survival with kidneys from a living donors have lead to an increase in living-donor renal transplantation in the therapy of end-stage renal disease. In Germany, with the implementation of a transplantation law in 1997 and due to improved surgical techniques (laparoscopy) the proportion of living renal donors has almost tripled during the last five years. The transplantation law also names the potential donors, including not only genetically related but also emotionally related donors. Inclusion criteria for living donation are age > 18 years, mental ability to give consent and an altruistic motivation (exclusion of financial benefits for the donor). If ABO blood group compatibility between donor and recipient is given and a cross match does not reveal immunologic obstacles a thorough medical and psychological examination must be performed with the potential donor. All risk factors for the donor beyond the actual operation must be excluded. Therefore all organ-systems have to be evaluated and risks for the donor as well as transferable pathologies and infections must be ruled out. International guidelines help to perform an efficient evaluation. Following organ donation the donor should be medically controlled as requested by law. Also, psychological counselling should be offered. The aim is to minimize risks for the single kidney and to recognize early potentially kidney damaging affections.

Anatomy is important basic subject for medicalstudents, both U.G. & P.G. Best method of Anatomy learning is by dissection on human cadavers, which remains principle teaching tool. Human cadavers for purpose of study are a scarcity with mushrooming of medical institutions in this country. Unclaimed bodies are no more origin of cadavers. Whole Body donation is the need of the hour. A Voluntary Body Donation is defined as the act of giving oneís Body after death for Medical research and education. In this article a survey was done in S.V.S. Medical & Dental Colleges Faculty members and medical exhibition visitors which include lawyers, engineers, teachers and others during the year of 2010. The body donation including organ donation and various factors such as age, religion, culture and donorís attitude are discussed. Body donation provides the students and medical researchers with unparalleled opportunities to study the human body. Computers nor books cannot totally replace body dissection in learning the anatomy.

    The report by Terasaki and colleagues in 1995 that the outcomes of spousal and biologically unrelated transplants were essentially the same as for 1-haplotype matched living related transplants changed the course of clinical transplantation. This article, entitled metaphorically "Beauty and the Beast", describes the dramatic change in the practice of living donor transplantation that followed. In the ensuing two decades, biologically unrelated living donor transplantation became commonplace in the developed world and reached its apotheosis in cross-country living donor paired exchange programs that have made transplantation accessible to many whose donors were deemed "incompatible". Such exchanges can indeed be thought of as a "thing of beauty". Sadly, the same observation was abused to exploit vulnerable donors, and the "beast" in the form of transplant tourism became a feature of transplantation in the developing world. The responsibility of the transplant community to protect the welfare of living donors and their recipients and the key role of trust in the evaluation of living donors is discussed.

    Background Currently, many transplantation centers do not follow former living kidney donors on a long-term basis. Several potential barriers have been identified to provide this follow-up of former living kidney donors, including concerns that donor insurance will not reimburse transplantation centers or primary care physicians for this care. Here, we report the rates at which different insurance companies reimbursed our transplantation center for follow-up visits of living donors. Methods We collected data on all yearly follow-up visits of living donors billed from January 1, 2007, to December 31, 2010, representing 82 different donors. Concurrent visits of their recipients were available for 47 recipients and were used as a control group. Results We find that most bills for follow-up visits of living kidney donors were paid by insurance companies, at a rate similar to the reimbursement for recipient follow-up care. Conclusions Our findings suggest that, for former donors with insurance, inadequate reimbursement should not be a barrier in providing follow-up care. PMID:23060280

    Careful evaluation of potential living kidney donors is crucial to assure the well being of the donors, especially because they do not gain any direct medical benefit from donation. This process also helps assess the quality and safety of the organs donated to the recipients. While all programs share these goals, donor selection criteria vary significantly among U.S. transplant centers. In part, this is due to the limited data that exists as to long-term outcomes among donors who are medically complex, or at higher risk for complications, such as those with hypertension, obesity, or lower kidney function. This article reviews available evidence regarding outcomes after living donation and current trends in U.S. practices, and seeks to provide practical guidance in evaluating high-risk potential living kidney donors.

    Limited organ availability in all countries has stimulated discussion about incentives to increase donation. Since 1988, Iran has operated the only government-sponsored paid living donor (LD) kidney transplant program. This article reviews aspects of the Living Unrelated Donor program and development of deceased donation in Iran. Available evidence indicates that in the partially regulated Iranian Model, the direct negotiation between donors and recipients fosters direct monetary relationship with no safeguards against mutual exploitation. Brokers, the black market and transplant tourism exist, and the waiting list has not been eliminated. Through comparison between the large deceased donor program in Shiraz and other centers in Iran, this article explores the association between paid donation and the development of a deceased donor program. Shiraz progressively eliminated paid donor transplants such that by 2011, 85% of kidney transplants in Shiraz compared with 27% across the rest of Iran's other centers were from deceased donors. Among 26 centers, Shiraz undertakes the largest number of deceased donor kidney transplants, most liver transplants, and all pancreas transplants. In conclusion, although many patients with end stage renal disease have received transplants through the paid living donation, the Iranian Model now has serious flaws and is potentially inhibiting substantial growth in deceased donor organ transplants in Iran.

    Previous studies have shown that kidney volume enhances the estimation of glomerular filtration rate (eGFR) in kidney donors. This study aimed to describe the phenomenon of compensatory hypertrophy after donor nephrectomy as measured on computerized tomographic (CT) scans. An institutional Domain Specific Review Board (DSRB)-approved study involved approaching kidney donors to have a follow up CT scan from 6 months to 1 year after surgery; 29 patients participated; 55% were female. Clinical chart review was performed, and the patient's remaining kidney volume was measured before and after surgery based on CT scans. eGFR was determined with the use of the Modification of Diet in Renal Disease equation. Mean parenchymal volume of the remaining kidney for this population (mean age, 44.3 ± 8.5 y) was 204.7 ± 82.5 cc before surgery and 250.5 ± 113.3 cc after donor nephrectomy. Compensatory hypertrophy occurred in 79.3% of patients (n = 23). Mean increase in remaining kidney volume was 22.4 ± 23.2% after donor nephrectomy in healthy individuals. Over a median follow-up of 52.9 ± 19.8 months, mean eGFR was 68.9 ± 12.4 mL/min/1.73 m(2), with 24.1% of patients (n = 7) in chronic kidney disease grade 3. Absolute and relative change in kidney volume was not associated with sex, race, surgical approach, or background of hypertension (P = NS). There was a trend of decreased hypertrophy with increasing age (P = .5; Spearman correlation, -0.12). In healthy kidney donors, compensatory hypertrophy of the remaining kidney occurs in 79.3% of the patients, with an average increment of about 22.4%. Older patients may have a blunted compensatory hypertrophy response after surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    long-term results for individuals diagnosed with end-stage renal disease. An essential element of the transplantation procedure is the voluntary donation of a healthy kidney by the live renal donor. Such an altruistic gift, which has no personal health benefit for the donor, is to be applauded and supported. The present research demonstrates that for some donors, particularly those living outside the metropolitan area, the gift may also include a range of financial costs to the donor. There is no prior research available on the financial impact of live renal donation for individuals living in non-metropolitan areas. Thus, this article is a seminal work in the area. The findings affirm 'rural disadvantage' by demonstrating that it is the live renal donors in non-metropolitan areas who are reporting financial concerns in relation to testing, hospitalisation and surgery for nephrectomy. It is the hope and expectation that the reporting on these costs will encourage further work in this area and the findings will be used for health policy and service delivery considerations.

  10. Expanding the live kidney donor pool: ethical considerations regarding altruistic donors, paired and pooled programs.

    In renal transplant, there is a well-known deficiency in organ supply relative to demand. Live donation provides superior results when compared with deceased donation including a better rate of graft success and fewer immunologic complications. This deficiency in organs leads to significant morbidity and mortality rates. Alternative avenues have been extensively explored that may expand the live donor pool. They include altruistic donation as well as paired and pooled exchange programs. Altruistic donation is a truly selfless act from a donor unknown to the recipient. Kidney paired donation involves 2 incompatible donor-recipient pairs swapping donors to produce compatibility. Pooled donation involves at least 2 pairs, and can take the form of domino chains in which altruistic input sets up a chain of transplants, in which each recipient's incompatible donor makes a donation for the next recipient. Despite application of these various methods, there lie extensive ethical issues surrounding them. Misconceptions frequently occur; for instance, the perceived benefit that donating an organ to a loved one is greater for a related donor than for an altruistic one. Additionally, it is frequently believed that immunologic incompatibility offers coerced donors liberation from surgery, and that overcoming these barriers by introducing exchange programs provides vulnerable donors less protection. This article explores these and other complex ethical issues surrounding the various methods of expanding the donor pool. The authors offer opinions that challenge the ethical issues and attempt to overcome those views that hinder progress in the field.

    Full Text Available Renal transplantation has profound improvements in mortality, morbidity, and overall quality of life compared to renal replacement therapy. This report aims to illustrate the use of ex-vivo partial nephrectomy in a patient with a renal angiomyolipoma prior to living donor transplantation. The surgical outcomes of the donor nephrectomy and recipient transplantation are reported with 2 years of follow-up. Both the donor and recipient are healthy and without any significant comorbidities. In conclusion, urologic techniques such as partial nephrectomy can be used to expand the living donor pool in carefully selected and well informed transplant recipients. Our experience demonstrated a safe and positive outcome for both the recipient and donor, and is consistent with other reported outcomes in the literature.

    Living donor lobar lung transplantation is a viable therapy for carefully selected patients with end-stage pulmonary disease. Its success is largely dependent upon donor outcome, including both physical and emotional factors. To date, there has been little focus on psychosocial outcomes of lobar lung donors. Retrospective evaluation of 15 of 20 living lobar lung transplant donors was performed. Donors underwent evaluation of pulmonary function after recovery from donor lobectomy. Participants completed two self-report questionnaires, the SF-36 Health Survey (SF-36) and the Beck Depression Inventory (BDI), as well as an open-ended psychiatric interview. After lobar donation, mean forced expiratory volume in 1 second (FEV(1)) decreased by 21 +/- 2%, forced vital capacity (FVC) decreased by 16 +/- 3%, total lung capacity (TLC) decreased by 15 +/- 3%, and single-breath diffusing capacity (DLCO) decreased by 14 +/- 4%. All subjects scored higher than the national average on both the physical and mental health components of the SF-36. The BDI scores showed no evidence of clinical depression. However, the subjective interviews elicited two common complaints: (1) a decline in exercise performance, not accounted for by resting lung function measurements; and (2) a dissatisfaction with the degree of acknowledgment of their donation. Living lobar lung transplant donors enjoy generally satisfactory physical and emotional health. Donors report positive feelings about donation, but wish to be recognized and valued by the transplant team and by the recipient. Despite preservation of lung function within the normal range, some donors also experience a subjective decline in exercise tolerance. Long-term medical and psychologic follow-up appears warranted to monitor symptoms of exercise impairment and to enhance the donor experience.

    To evaluate the living donor selection, donor hepatectomy technique, and surgical complication in living donor liver transplantation. From June 2007 to July 2008, 74 consecutive cases living donor hepatectomy were performed by the same surgical team. Seventy-four donors (64 males and 10 females) with a mean age of 29.2 years old passed the donor liver assessment and evaluation program successfully. The hepatectomy procedure types contained right liver resection (n = 72), of which 27 cases harvested the middle hepatic vein and 45 cases not, left liver resection contain middle hepatic vein (n = 1) and left lateral resection (n = 1). Of all the donors, operation time was (6.5 +/- 6.2) hours, the mean blood loss was 300 ml (100 - 500 ml) and didn't accept foreign blood transfusion. The maximum alanine aminotransferase (ALT) level was (229.5 +/- 108.6) U/L, the ALT returned to normal time was (12.7 +/- 4.8) d, the maximum total bilirubin (TB) level was (78.7 +/- 44.3) micromol/L, the TB returned to normal time was (8.8 +/- 2.7) d, and the mean hospital stay time was 14 days (7 - 28 d). The complications included bile leak (n = 1), cut surface hemorrhage (n = 1) and anaphylactoid purpura (n = 1). All the donors returned to normal work and life finally. Precisely evaluating donor blood vascular and biliary anatomy before operation, keeping the blood vascular and bile duct integrity during operation and monitoring complication to solve it immediately after operation is crucial to ensure donor safety and recovering successfully.

    Full Text Available Hypophosphatemia has been described in patients undergoing right hepatectomy for liver cancer and in living donors for liver transplantation who also received total parenteral nutrition. At the study centre, significant hypophosphatemia (0.36 mmol/L or less requiring intravenous replacement was seen in two of the first nine living donors for adult-to-adult liver transplantation. To determine the frequency of hypophosphatemia in living donors, the authors obtained phosphate levels on stored serum samples from postoperative days 0, 1, 3 and 7 in all nine patients, none of whom were on total parenteral nutrition. Within the first week, hypophosphatemia developed in 55.6% of patients and phosphate levels returned to normal by day 7 in all nine patients. One patient had normal phosphate levels during the first week, but had profound hypophosphatemia (0.32 mmol/L on day 14 when he presented with a Staphylococcus aureus infection of a bile collection and significant hypoxemia. The extent of hepatectomy and the rate of liver regeneration, estimated by baseline and postoperative day 7 volumetric computed tomography scans, did not correlate with the development of hypophosphatemia. In conclusion, hypophosphatemia is common in living donors undergoing right hepatectomy and may be associated with complications. All living donors should be monitored for the development of hypophosphatemia during the first two postoperative weeks.

    2012-02-01

    Living kidney donor evaluations and follow-up have previously been addressed mostly by transplant physicians and surgeons. However, this area is significantly informed by basic principles of renal physiology and is of increasing clinical interest to general nephrologists. The general nephrology community is increasingly involved in evaluating the suitability of potential donors and in following them after donation when questions are raised about low GFR, hypertension, and other renal concerns. This article focuses on some of the most central and common issues that arise in evaluating potential donors and attempts to provide guidance on the basis of our review of the living donor literature, extrapolations from the general nephrology literature, and our own clinical experience.

    The initial success of living donor liver transplantation (LDLT) in the United States has resulted in a growing interest in this procedure. The impact of LDLT on liver transplantation will depend in part on the proportion of patients considered medically suitable for LDLT and the identification of suitable donors. We report the outcome of our evaluation of the first 100 potential transplant recipients for LDLT at the University of Colorado Health Sciences Center (Denver, CO). All patients considered for LDLT had first been approved for conventional liver transplantation by the Liver Transplant Selection Committee and met the listing criteria of United Network for Organ Sharing status 1, 2A, or 2B. Once listed, those patients deemed suitable for LDLT were given the option to consider LDLT and approach potential donors. Donors were evaluated with a preliminary screening questionnaire, followed by formal evaluation. Of the 100 potential transplant recipients evaluated, 51 were initially rejected based on recipient characteristics that included imminent cadaveric transplantation (8 patients), refusal of evaluation (4 patients), lack of financial approval (6 patients), and medical, psychosocial, or surgical problems (33 patients). Of the remaining 49 patients, considered ideal candidates for LDLT, 24 patients were unable to identify a suitable donor for evaluation. Twenty-six donors were evaluated for the remaining 25 potential transplant recipients. Eleven donors were rejected: 9 donors for medical reasons and 2 donors who refused donation after being medically approved. The remaining 15 donor-recipient pairs underwent LDLT. Using our criteria for the selection of recipients and donors for LDLT gave the following results: (1) 51 of 100 potential transplant recipients (51%) were rejected for recipient issues, (2) only 15 of the remaining 49 potential transplant recipients (30%) were able to identify an acceptable donor, and (3) 15 of 100 potential living donor

    Full Text Available This manuscript is a survey of the halachic attitudes toward organ transplant procedures from a living donor which can be defined as life-saving procedures for the recipient or at least life-prolonging procedures. Three fundamental problems concerning the halachic aspects of such transplantation are discussed in detail: the danger to the donor, donation under coercion, and the sale of organs and tissues. The terms “halacha” and “Jewish law” are defined in the introduction.

    Kidney transplantation from living donors is widely performed all over the world. Living nephrectomy for transplantation has no direct advantages for the donor other than increased self-esteem, but it at least remains an extremely safe procedure, with a worldwide overall mortality of 0.03%. This theoretical risk for the donor seems to be justified by the socioeconomic advantages and increased quality of life of the recipient, especially in selected cases, such as pediatric patients, when living donor kidney transplantation can be performed in a preuremic phase, avoiding the psychological and physical stress of dialysis, which in children is not well tolerated and cannot prevent retarded growth. According to the Ethical Council of the Transplantation Society, commercialism must be effectively prevented, not only for ethical but also medical reasons. The risks are too high, not only for the donors, but also for the recipients, as a consequence of poor donor screening and evaluation with consequent transmission of human immunodeficiency virus (HIV) or other infective agents, as well as of inappropriate medical and surgical management of donors and also recipients, who are often discharged too early. Most public or private insurance companies consider kidney donation a safe procedure without long-term impairment and therefore do not increase the premium, whereas recipient insurance of course should cover hospital fees for the donors. "Rewarded gifting" or other financial incentives to compensate for the inconvenience and loss of income related to the donation are not advisable, at least in our opinion. Our Center does not perform anonymous living organ donation or "cross-over" transplantation.

    HBsAg positive subjects belonging to high risk groups and voluntary blood donors were analysed for prevalence of HBsAg among various groups of subjects for ascertaining the carrier status among the voluntary blood donors, HBsAg subtype distribution, and association of HBsAg with blood groups and caste or religion. The prevalence of HBsAg varied from 2.02 per cent in voluntary blood donors to 58.38 per cent in patients of acute viral hepatitis. 70.5 per cent subjects had subtype 'ay' while 23.9 per cent of the subjects had subtype 'ad'. We also found compound 'ady' subtype in 5.6 per cent of our subjects. HBsAg/adr, a subtype not usually prevalent in India, was found in 30 of the 90 'ad' sera. Co-occurrence of HBsAg and anti-HBs was noted in 9 subjects. Homotypic anti-HBs was found to occur together mainly in voluntary blood donors, while heterotypic anti-HBs was found to occur together mainly multi-transfused patients. There was no significant correlation between HBsAg and blood group antigens and a relatively higher incidence of HBsAg among the Jain community was observed.

    BACKGROUND:The safety of donors in living donor liver transplantation (LDLT) should be the primary consideration. The aim of this study was to report our experience in increasing the safety of donors in LDLTs using right lobe grafts. METHODS:We retrospectively studied 37 living donors of right lobe grafts from January 2002 to March 2006. The measures for increasing the safety of donors in LDLT included carefully selected donors, preoperative evaluation by ultrasonography, angiography and computed tomography; and necessary intraoperative cholangiography and ultrasonography. Right lobe grafts were obtained using an ultrasonic dissector without inlfow vascular occlusion on the right side of the middle hepatic vein. The standard liver volume and the ratio of left lobe volume to standard liver volume were calculated. RESULTS:There was no donor mortality in our group. Postoperative complications only included bile leakage (1 donor), biliary stricture (1) and portal vein thrombosis (1). All donors recovered well and resumed their previous occupations. In recipients, complications included acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left subphrenic abscess (1) and pulmonary infection (1). The mortality rate of recipients was 5.4% (2/37); one recipient with pulmonary infection died from multiple organ failure and another from occurrence of primary disease. CONCLUSIONS:The ifrst consideration in adult-to-adult LDLT is the safety of donors. The donation of a right lobe graft is safe for adults if the remnant hepatic vasculature and bile duct are ensured, and the volume of the remnant liver exceeds 35% of the total liver volume.

    Living donor kidney transplantation has developed very heterogeneously worldwide despite excellent results and without taking into account the context of global organ shortage. Such a heterogeneity highlights persistent ethical issues, whereas organ trafficking is emerging as an organized transplant tourism reinforcing the need for strong national legal frameworks. Despite its powerful regulation system, which ensures standardization, transparency and accountability of support for donation, France remains reluctant to enlarge the circle of legal donors, whereas it would be the first step to give a greater role to living organ donation.

    Full Text Available Objectives: The introduction of the living donor liver transplantation (LDLT in Egypt as in elsewhere, has raised important psychological conflicts and ethical questions. The objective of this study was to get better understanding of the potential donors’ motives towards LDLT.Methods:This study was conducted on consecutive 193 living –liver donors who underwent partial hepatectomy as donors for LDLT during the period between April 2003 and January 2013, at the National Liver Institute Menoufeyia University, Egypt. Potential donors were thoroughly evaluated preoperatively through a screening questionnaire and interviews as regard their demographic data, relationship to the potential recipient and motives towards proceeding to surgery. They were assured that the information shared between them and the transplant centre is confidential. Results.The donors’ mean age was 25.53± 6.39 years with a range of 18-45 years. Males represented 64.7 % and females were 35.3%. The most common donors (32.1%, n_62, were sons and daughters to their parents (sons: n_43, daughters: n_19 while parents to their offsprings represent 15% (mothers: n_21, fathers: n_8. Brothers and sisters represent 16.5 % (brothers: n_22, sisters: n_10. Nephews & nieces giving their uncles or aunts were 14%. The number of wives donating to their husbands was 11 (5.7%. Interestingly, there was no single husband who donated his wife. Among the remaining donors, there were 11 cousins & one uncle. Unrelated donors were 20 (10.4%. Several factors seemed to contribute to motivation for donation: the seriousness of the potential recipient condition, the relationship and personal history of the donor to the potential recipient, the religious beliefs, the trust in the health care system, and family dynamics and obligations.Conclusions. Absolute absence of coercion on the living-liver donor’s motives may not be realistic because of the serious condition of the potential recipient. It is

    Some living kidney donors encounter difficulties obtaining life insurance, despite previous surveys of insurance companies reporting otherwise. To better understand the effect of donation on insurability, we contacted offices of life insurance companies in five major cities in Canada to obtain $100 000 of life insurance (20-year term) for 40 fictitious living kidney donors and 40 paired controls. These profiles were matched on age, gender, family history of kidney disease and presence of hypertension. The companies were blinded to data collection. The study protocol was reviewed by the Office of Research Ethics. The main study outcomes were the annual premium quoted and total time spent on the phone with the insurance agent. All donor and control profiles received a quote, with no significant difference in the premium quoted (medians $190 vs. $209, p = 0.89). More time was spent on the phone for donor compared to control profiles, but the absolute difference was small (medians 9.5 vs. 7.0 min, p = 0.046). Age, gender, family history of kidney disease and new-onset hypertension had no further effect on donor insurability in regression analysis. We found no evidence that kidney donors were disadvantaged in the first step of applying for life insurance. The effect donation has on subsequent phases of insurance underwriting remains to be studied.

Since 1986, 127 living related potential donors have been evaluated and 100 patients have been transplanted at the Ibn Rochd UHC in Casablanca. We retrospectively studied the potential donors and determined their profile and the exclusion criteria. The mean age at the time of donation was 37 +/- 11 years (range 18-66 years and 60% of donors were women. The predominant sources of donors were sisters, brothers and mothers of recipients in 34%, 31% and 24% respectively. Forty three percent of them were married, 20% housewives and 17% unemployed. In addition, 37% were illiterate, 45% school graduates, and 18% university graduates. Donors and recipients were incom-plete HLA match in 72.7%, identical in 19% and different in 8.3%. The cross matching test was negative in all cases. The mean plasma creatinine was 0.8 ± 0.1 mg/dL with mean creatinine clearance of 103.16 ± 18.18 mL/min.

    Full Text Available Introduction. Living donor liver transplantation has proved to be an effective, safe and radical treatment modality for patients with end-stage liver diseases. Left lateral section (LLS of donor’s liver is used in pediatric recipients. Laparoscopic LLS procurement was fi rst described by D. Cherqui in 2002. At present, this technique is routinely used only by 5 hospitals in the world. However, up to date, some authors consider it to be a new standard to perform such a surgery in living donors.Aim. To analyze the fi rst Russian experience in laparoscopic left lateral sectionectomy (LapLLS in living related donor.Materials and methods. From May to September 2016 fi ve LapLLS were performed in living donors. In all cases donors were women (mothers in 4 cases and aunt in 1 case. Recipients were children aged from 6 months through 3 years with body mass from 5.6 to 12.5 kg. Liver transection was carried out under conditions of maintained blood supply. Parenchymal transection was performed using a harmonic scalpel, bipolar coagulation and ultrasound dissection.Results. Average donor age was 32 ± 5 years. Average operation time was 287 ± 16 min. Average LLS graft weight was 220 ± 16 g. Intraoperative blood loss did not exceed 100 ml (95 ± 5 ml. Donors were discharged on the 3rd–4th post-op day. There were no postoperative complications in donors. Recipients were also characterized by a standard course of the postoperative period.Conclusion. LapLLS is an effective and safe method with several advantages. Primarily, these are early rehabilitation of the donors and shortening of the hospital stay, which are important for the quick return to normal way of live. Excellent visualization of anatomical structures, including vascular and biliary ones, allows performing precise selection. In addition, good cosmetic effect is also an important aspect.

    Full Text Available Background. In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors. Method. We retrospectively identified 14 patients who received renal allograft from spousal donors between 1996 and 2009 (group I. The control group consisted of 14 patients who got graft from related donor retrieved from the database and matched than with respect to sex, age, kidney disease, immunological and viral pretransplant status, the initial method of the end stage renal disease treatment and ABO compatibility. In the follow-up period of 41 ± 38 months we recorded immunosuppressive therapy, surgical complications, episodes of acute rejection, CMV infection and graft function, assessed by serum creatinine levels at the beginning and in the end of the follow-up period. All patients had pretransplant negative cross-match. In ABO incompatible patients pretransplant isoagglutinine titer was zero. Results. The patients with a spousal donor had worse HLA matching. There were no significant differences between the groups in surgical, infective, immunological complications and graft function. Two patients from the group I returned to hemodialysis after 82 and 22 months due to serious comorbidities. Conclusion. In spite of the worse HLA matching, graft survival and function of renal grafts from spousal donors were as good as those retrieved from related donors.

    Nowadays, laparoscopic donor nephrectomy (LDN) has become the gold standard to procure live donor kidneys. As the relationship between donor and recipient loosens, it becomes of even greater importance to optimize safety and comfort of the surgical procedure. Low-pressure pneumoperitoneum has been shown to reduce pain scores after laparoscopic cholecystectomy. Live kidney donors may also benefit from the use of low pressure during LDN. To evaluate feasibility and efficacy to reduce post-operative pain, we performed a randomized blinded study. Twenty donors were randomly assigned to standard (14 mmHg) or low (7 mmHg) pressure during LDN. One conversion from low to standard pressure was indicated by protocol due to lack of progression. Intention-to-treat analysis showed that low pressure resulted in a significantly longer skin-to-skin time (149 ± 86 vs. 111 ± 19 min), higher urine output during pneumoperitoneum (23 ± 35 vs. 11 ± 20 mL/h), lower cumulative overall pain score after 72 h (9.4 ± 3.2 vs. 13.5 ± 4.5), lower deep intra-abdominal pain score (11 ± 3.3 vs. 7.5 ± 3.1), and a lower cumulative overall referred pain score (1.8 ± 1.9 vs. 4.2 ± 3). Donor serum creatinine levels, complications, and quality of life dimensions were not significantly different. Our data show that low-pressure pneumoperitoneum during LDN is feasible and may contribute to increase live donors' comfort during the early post-operative phase.

    In the United States, there is a national shortage of organs donated for transplant. Among the solid organs, most often kidneys are donated by living donors, but the lack of information and complicated processes limit the number of individuals who serve as living kidney donors. Social media can be a tool for advocacy, educating the public about the need, process, and outcomes of live kidney donors, yet little is known about social media use by kidney transplant patients. The purpose of this study was to examine the social media use of potential kidney transplant patients and their willingness to use social media and their networks to advocate and educate about living kidney donation. Using a validated survey, we modified the instrument to apply to the patient population of interest attending the Medical University of South Carolina, Charleston, SC, USA. The questions on the survey inquired about current social media use, sites visited, frequency and duration of social media use, and willingness to use social media to share the need for living kidney donors. We asked patients who had received a transplant and those awaiting a transplant to complete the survey during an office visit. Participation was voluntary. A total of 199 patients completed the survey. Approximately half of all kidney transplant patients surveyed used social media (104/199, 52.3%), and approximately one-third (66/199, 33.2%) had more than 100 friends in their social media network. Facebook was the most popular site, and 51% (102/199) reported that they would be willing to post information about living kidney donation on their social networks. More than a quarter of the sample (75/199, 37.7%) had posted about their health status in the past. Social media holds great promise for health-related education and awareness. Our study shows the current social media use of kidney transplant patients. In turn, such information can be used to design interventions to ensure appropriate decision making about

    Background Multidetector-row CT (MDCT) has been evolving to the standard evaluating method of potential living donor in most centers, and can provide excellent details for selecting candidates and determining surgical technique.This study aimed to assess the value of MDCT in evaluation of the anatomy of living kidney donors and to reveal the prevalence of renal vascular variations in a Chinese population.Methods One hundred and four potential donors underwent MDCT and the data sets were post-processed for reformatted images with various techniques, such as maximum intensity projection (MIP), a volume-rendering technique (VR), and multiplanar reformation (MPR). Donor nephrectomies were performed on 97 candidates after MDCT evaluation with the findings during surgery constituting the standard of reference. Resulting MDCT images were compared with actual anatomy found during surgery. Results The MDCT images accurately displayed the anatomic structure of the main renal arteries and veins as well as the upper ureters, except in one case with horseshoe kidney. The prevalence of accessory arteries revealed in images was 27.2% (28/103) and early branching was found in 12.6% (13/103). Compared with findings during surgery, the detection of accessory arteries in MDCT images was 85.7% (6/7), and the detection of larger accessory arteries (>1.5 mm in diameter) was 100%. Detection of early branching was 100%.Conclusion MDCT helps accurately evaluate the renal anatomy of potential donors thus facilitating the planning of surgery.

    At the 2010 Conference on Living Kidney Donor follow-up, a workgroup was convened to comment on the state of the evidence in 4 broad areas: (a) health-related quality of life postdonation; (b) donors' financial and economic concerns; (c) outcomes issues specific to newer areas of donation, namely, kidney exchange and anonymous (directed and nondirected) donation; and (d) the role of informed consent in relation to postdonation psychosocial outcomes. The workgroup sought to offer recommendations regarding research priorities for the next decade and data collection strategies to accomplish the needed research. The workgroup concluded that there has been little consideration of the nature or predictors of any long-term psychosocial outcomes in living donors. In some areas (eg, kidney exchange and anonymous donation), there is limited information on outcomes even in the early aftermath of donation. Across all 4 psychosocial areas, prospective studies are needed that follow donors to examine the course of development and/or resolution of any donation-related difficulties. The formation of a national registry to routinely collect psychosocial follow-up data may be an efficient strategy to monitor donor outcomes in both the short- and long-term years after donation.

    End-stage liver disease,due to cholestatic liver diseases with an autoimmune background such as primary biliary cirrhosis(PBC)and primary sclerosing cholangitis(PSC),is considered a good indication for liver transplantation.Excellent overall patient and graft outcomes,based mostly on the experience from deceased donor liver ransplantation(DDLT),have been reported.Due to the limited number of oraan donations from deceased donors in most Asian countries,living donor liver transplantation(LDLT)is the mainstream treatment for end-stage liver disease,including that resulting from PBC and PSC.Although the initial experiences with LDLT for PBC and PSC seem satisfactory or comparable to that with DLT,some aspects,including the timing of transplantation,the risk of recurrent disease,and its long-term clinical implications,require further evaluation.Whether or not the long-term outcomes of LDLT from a biologically related donor are equivalent to that of DDLT requires further observations.The clinical course following LDLT may be affected by he genetic background shared between the recipient and the living related donor.(C)2008 The WJG Press.All rights reserved.

    To assess acceptance and acceptable estimated mortality levels for right lobe adult-to-adult living related liver transplantation for the medical and allied professions. A paper questionnaire was sent to the physicians practicing with the French Graft Agency (Etablissement Français des Greffes) and to all nurses and ancillary staff of the Paul Brousse Hospital Hepatobiliary Center. Responses were received from surgeons: 38/73; internists specialized in hepatology: 44/120; nurses: 98/100; health care assistants: 45/86; others: 17/20. Acceptance of living donor transplantation is above average for all professional categories and indications may be extended including patients with cancer. Acceptable mortality for the donor was 4%, except among internists (0.7%). Currently, the real risk of mortality for the donor (1%) is lower. Acceptable mortality for the recipient was between 15 and 20%. Acceptance of adult living donor liver transplantation among health care professionals is clearly above average. Thus the psychological involvement of transplantation teams, which is very strong in such situations, should not hamper the development of this type of transplantation.

    2012-01-01

    Background Hepatitis B virus (HBV) is still one of the serious infectious risks for the blood transfusion safety in China. One plausible reason is the emergence of the variants in the major antigenic alpha determinant within the major hydrophilic region (MHR) of hepatitis B surface antigen (HBsAg), which have been assumed to evade the immune surveillance and pose a challenge to the disease diagnosis. It is well documented that some commercial ELISA kits could detect the wild-type but not the mutant viruses. The high prevalence of HBV in China also impaired the application of nucleic acid testing (NAT) in the improvement of blood security. Molecular epidemiological study of HBsAg variations in China is still limited. This study was designed to identify the prevalence of mutations in the HBsAg in voluntary blood donors in Nanjing, China. Methods A total of 20,326 blood units were enrolled in this study, 39 donors were positive for HBV S gene in the nested-PCR. Mutations in the major hydrophilic region (MHR; aa 99-169) were identified by direct sequencing of S region. Results Among of 20,326 blood units in the Red Cross Transfusion Center of Nanjing from October 2008 to April 2009, 296 samples (1.46%, 296/20,326) were HBsAg positive in the 2 successive rounds of the ELISA test. In these HBsAg positive units, HBV S gene could be successfully amplified from 39 donors (13.18%, 39/296) in the nested-PCR. Sequence analysis revealed that 32 strains (82.1%, 32/39) belong to genotype B, 7 strains (17.9%, 7/39) to genotype C. Besides well known G145R, widely dispersed variations in the MHR of S region, were observed in 20 samples of all the strains sequenced. Conclusions HBV/B and HBV/C are dominant in Nanjing, China. The mutations in the MHR of HBsAg associated with disease diagnosis are common. PMID:22500577

    AIM: To investigate the health related quality of life (HRQoL) and psychological outcome of donors after living donor liver transplantation. METHODS: Participants were 92 consecutive liver transplant donors who underwent hepatectomy without middle hepatic vein at West China Hospital of Sichuan University between January 2007 and September 2010. HRQoL was measured using the Chinese version of the Medical Outcomes Study Short Form-36 (SF-36), and psychological symptoms were measured using the Symptom Checklist-90-Revised (SCL-90-R). Data collected from donors were compared to previously published data from the general population. Clinical and demographic data were collected from medical records and questionnaires. RESULTS: The general health score of the SF-36 was significantly lower in females (59.78 ± 12.25) than in males (75.83 ± 22.09). Donors more than 40 years old scored higher in social functioning (85.71 ± 14.59) and mental health (82.61 ± 20.00) than those younger than 40 (75.00 ± 12.13, 68.89 ± 12.98; social functioning and mental health, respectively). Donors who had surgery more than two years prior to the study scored highest in physical functioning (P = 0.001) and bodily pain (P = 0.042) while those less than one year from surgery scored lowest. The health of the liver recipient significantly influenced the general health (P = 0.042), social functioning (P = 0.010), and roleemotional (P = 0.028) of donors. Donors with full-time employment scored highest in role-physical (P = 0.005), vitality (P = 0.001), social functioning (P = 0.016), mental health (P < 0.001), the physical component summary scale (P < 0.001), and the mental component summary scale (MCS) (P < 0.001). Psychological measures indicated that donors were healthier than the general population in obsessive-compulsive behavior, interpersonal sensitivity, phobic anxiety, and paranoid ideation. The MCS of the SF-36 was significantly correlated with most symptom scores of the SCL-90-R

    Living kidney donation is an important option for patients with end-stage renal disease (ESRD), and has improved life expectancy and quality for patients otherwise requiring maintenance dialysis or deceased-donor transplantation. Given the favorable outcomes of live donation and the shortage of organs to transplant, individuals with potentially unfavorable demographic and clinical characteristics are increasingly being permitted to donate kidneys. While this trend has successfully expanded the live donor pool, it has raised concerns as to which acceptance criteria are safe. This review aims to summarize the existing literature on the outcomes of transplantation from medically complex, living kidney donors, including both donor and recipient outcomes when available.

    Full Text Available PURPOSE: Laparoscopic live donor nephrectomy has acquired an important role in the era of minimally invasive surgery. Laparoscopic harvesting of the right kidney is technically more challenging than that of the left kidney because of the short right renal vein and the need to retract the liver away from the right kidney. The aim of this article is to report our experience with right laparoscopic live donor nephrectomies. MATERIALS AND METHODS: We performed a retrospective review of 28 patients who underwent right laparoscopic donor nephrectomies at our service. Operative data and postoperative outcomes were collected, including surgical time, estimated blood loss, warm ischemia time, length of hospital stay, conversion to laparotomy and complications. RESULTS: The procedure was performed successfully in all 28 patients. The mean operative time was 83.8 minutes (range 45 to 180 minutes, with an estimated blood loss of 111.4 mL (range 40 to 350 mL and warm ischemia time of 3 minutes (range 1.5 to 8 minutes. No donor needed conversion to open surgery and all kidneys showed immediate function after implantation. The average time to initial fluid intake was 12 hours (range 8 to 24 hours. Two cases of postoperative ileus and a case of hematoma on the hand-port site were observed. The mean postoperative hospital stay was 3 days (range 1 to 7 days. CONCLUSIONS: Our data confirm the safety and feasibility of right laparoscopic donor nephrectomy and we believe that the right kidney should not be avoided for laparoscopic donor nephrectomy when indicated.

    Laparoendoscopic single-site (LESS) surgery has been shown to be feasible in living donor nephrectomies (DNs). Obesity is an established risk factor for perioperative morbidity. We sought to determine whether LESS-DN is safe and effective in the obese (body mass index [BMI] ≥30 kg/m(2)) population. Between August 2009 and September 2010, 125 consecutive LESS-DN were performed; 32 patients were obese. This group was matched to 32 nonobese LESS-DN (BMI obese conventional laparoscopic DN (obese LAP-DN) patients, and 32 nonobese LAP-DN patients. Comparison parameters included organ recovery time, operative time, estimated blood loss (EBL), warm ischemia time (WIT), incision length, complications, and recipient allograft function. Demographic data were similar between the groups, except BMI (P>0.0001). Organ recovery time, EBL, WIT, complications, and recipient allograft function were similar between the obese LESS-DN group and the other three groups (P>0.05). Total operative time was longer in the obese LESS-DN compared with the nonobese LAP-DN (Pobese LESS-DN group compared with either LAP group (Pobese donor cases were converted to hand-assisted laparoscopy). Our results indicate that LESS-DN can be performed safely in obese donors without increased donor morbidity and similar recipient allograft outcomes compared with ideal-sized donors as well as with conventional LAP-DN patients.

    Full Text Available In the Maghreb, organ failure constitutes a major public health problem, especially given the increasing number of patients with chronic renal failure and the high cost of care. In this study, we attempted to seek the recommendations, through a questionnaire, of various officials related to organ transplantation as well as leaders of ethics committees and religious groups in different countries of the Maghreb. The objective was to improve the rate of organ donation and transplantation. We received 36 replies (62% within the prescribed time limit. In our survey, 83% of the respondents felt that living donor transplantation should be promoted initially, followed gradually by measures to increase cadaver donor transplantation to achieve a target of about 30 transplants with cadaver kidney donors per million inhabitants. To expand the donor pool, 83% of the respondents proposed to expand the family circle to include the spouse and inlaws. To improve the cadaver donation activity, one should improve the organizational aspects to ensure at least 50 renal transplantations per year (100% and provide material motivation to the treatment team proportional to the activity of organ donation and transplantation. Finally, 93% of the respondents suggested suitable moral motivation of the donors.

  3. Delayed Gastric Emptying after Living Donor Hepatectomy for Liver Transplantation

    Full Text Available Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy.

    To evaluate the morbidity of living donor kidney harvesting and the long-term medical consequences and impact on quality of life (QoL). Retrospective analysis of medical and surgical data for 114 living kidney donors in a single teaching hospital between 1977 and 2005. Complications were evaluated in relation to the surgical approach and body mass index (BMI) using a Chi-square test or Fisher's exact test. Changes in renal function (serum creatinine, creatinine clearance), proteinuria and blood pressure (BP) were studied by Student's t test or a Mann-Whitney U or Wilcoxon nonparametric test. Long-term QoL was evaluated by the MOS SF-36 questionnaire and a local questionnaire and was then compared to that of the French general population. The median follow-up was 63 months. The morbidity of kidney harvesting was significantly correlated with the surgical approach (p = 0.018) and a BMI > or = 25 kg/m2 (p = 0.014). No mortality was observed in this series. A moderate elevation of serum creatinine was observed during follow-up (mean serum creatinine increased from 82.2 micromol/l [+/- 16.3] to 104.5 micromol/l [+/- 19.9]), and mean creatinine clearance decreased from 113.4 ml/min [+/- 27.6] to 76 ml/min [+/- 29.9]. Little impact was observed on proteinuria and BP and QoL was not altered by kidney harvesting. The perioperative complication rate is correlated with BMI and a flank incision. Kidney harvesting lowers glomerular filtration, but clearance remained stable during follow-up. Macroalbuminuria or hypertension may be observed, but their frequency is not higher than in the general population. The QoL of living donors is not altered. Clear information for the general public would allow promotion of living donor transplantation.

    There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients. The patient's demographic data, preoperative and intraoperative parameters, and outcomes were recorded. Acute kidney injury was found in 27 (12.3%) recipients. In recipients with acute kidney injury, female population, model for end-stage liver disease score, norepinephrine requirement, duration of mean arterial pressure less than 60 mmHg, the usage of gelatin and erythrocyte suspension and blood loss were significantly higher than recipients with nonacute kidney injury (for all p5 mL kg-1 and duration of MAP less than 60 mmHg ≥5.5 minutes respectively (for all p<0.05). In living donor liver transplantation recipients, serum tacrolimus levels, intraoperative blood loss, hypotension period and the usage of gelatin may be risk factors for acute kidney injury in the early postoperative period.

    AIM: To investigate the incidence and risk factors of late-onset acute rejection (LAR) and to clarify the effectiveness of our immunosuppressive regime consisting of life-long administration of tacrolimus and steroids.METHODS: Adult living donor liver transplantation recipients (n = 204) who survived more than 6 mo after living donor liver transplantation were enrolled.Immunosuppression was achieved using tacrolimus and methylprednisolone. When adverse effects of tacrolimus were detected, the patient was switched to cyclosporine. Six months after transplantation,tacrolimus or cyclosporine was carefully maintained at a therapeutic level. The methylprednisolone dosage was maintained at 0.05 mg/kg per day by oral administration.Acute rejections that occurred more than 6 mo after the operation were defined as late-onset. The median followup period was 34 mo.RESULTS: LAR was observed in 15 cases (7%) and no chronic rejection was observed. The incidence of hyperlipidemia, chronic renal failure, new-onset posttransplantation diabetes, and deep fungal infection were 13%, 2%, 24%, and 17%, respectively. Conversion from tacrolimus to cyclosporine was required in 38 patients (19%). Multivariate analysis revealed that a cyclosporinebased regimen was significantly associated with LAR.CONCLUSION: Both LAR and drug-induced adverse events happen at a low incidence, supporting the safety and efficacy of the present immunosuppression regimen for living donor liver transplantation.

    2011-01-01

    Brazil has established the largest public kidney transplantation system in the world .46.2% of transplants in 2008 came from living donors. The vast majority of these involved relatives of the recipient; less than 8% came from unrelated donors. In 2008, Brazil's health minister proposed banning unrelated donors in kidney transplantation. A large number of the over 35,000 Brazilians on the waiting list for a kidney would be denied a transplant without the use of unrelated donors. Brazilian culture has a unique feature, the "informal family", that is not legally recognised as a "family entity and is bound by affection rather than genetic or legal ties. It is vital that Brazil establishes a regulated, standardised, and ethical system of organ procurement; creates awareness about transplantation in physicians and the public; upgrades facilities and standardises medical care, and enforces legislation for transplantation. However, outlawing the use of unrelated donors would result in injustice for many patients who seek kidneys.

    Full Text Available OBJECTIVE: To assess results obtained with the authors' technique of right hand-assisted laparoscopic nephrectomy in living kidney donors. MATERIALS AND METHODS: We retrospectively analyzed 16 kidney donors who underwent hand-assisted right laparoscopic nephrectomy from February 2001 to July 2004. Among these patients, 7 were male and 9 were female, with mean age ranging between 22 and 58 years (mean 35.75. RESULTS: Surgical time ranged from 55 to 210 minutes (mean 127.81 min and warm ischemia time from 2 to 6 minutes (mean 3.78 min with mean intra-operative blood loss estimated at 90.62 mL. There was no need for conversion in any case. Discharge from hospital occurred between the 3rd and 6th days (mean 3.81. On the graft assessment, immediate diuresis was seen in 15 cases (93.75% and serum creatinine on the 7th post-operative day was 1.60 mg/dL on average. Renal vein thrombosis occurred in 1 patient (6.25% who required graft removal, and lymphocele was seen in 1 recipient (6.25%. CONCLUSION: Hand-assisted right laparoscopic nephrectomy in living donors is a safe and effective alternative to open nephrectomy. Despite a greater technical difficulty, the procedure presented low postoperative morbidity providing good morphological and functional quality of the graft on the recipient.

  12. Ethical issues in living organ donation: donor autonomy and beyond.

    Science.gov (United States)

    Spital, A

    2001-07-01

    Despite nearly 50 years of experience with living kidney donation, ethical questions about this practice continue to haunt us today. In this editorial I will address two of them: (1) Given the possibility of limited understanding and coercion, how can we be sure that a person who offers to donate an organ is acting autonomously? and (2) Do people have a right to donate? The universal requirement for informed consent is the traditional method for ensuring that a person is acting autonomously. But, while obtaining fully informed consent is desirable, it may not always be achievable or necessary. When the recipient is very dear to the potential donor, the donor may base his decision primarily on care and concern rather than on a careful weighing of risks and benefits. I will argue that consent that emanates from such deep affection should be considered just as valid as consent that is fully informed. But consent is not enough. There is no absolute right to donate an organ. If there were such a right, then some physician would be obligated to remove an offered organ upon request, regardless of the risks involved. I do not believe that physicians have such an obligation. Physicians are moral agents who are responsible for their actions and for the welfare of their patients. Therefore, while the values and goals of the potential donor should be given great weight during the decision-making process, physicians may justifiably refuse to participate in living organ donation when they believe that the risks for the donor outweigh the benefits.

    Development of live donor kidney transplantation (LDKT) programs has intensified debate regarding acceptability of certain donor categories and potential commercialization. Concerning these issues, we surveyed the views of medical and nursing staff caring for patients with renal failure and renal transplant recipients and donors. Participants were recruited from a tertiary transplant unit and invited to complete an anonymous questionnaire. Four hundred and sixty-four participants completed the questionnaire (42% response). One hundred and sixty-eight (36.2%) were health care professionals and 296 (63.8%) patients; 85.6% of participants were willing to donate to their children, 80.2% to siblings, 80.8% to parents, 72% to a non-blood-related relative or friend, and 15.3% to a stranger. If participants had hypothetical renal failure, they were prepared to accept a kidney from a parent (79.5%), sibling (78.7%), child (56.3%), a non-blood-related relative or friend (79.3%), or stranger (54.1%). Regarding commercialization, responders' attitudes were that the donor should not accept financial reward (29.1%), be compensated for expenses only (60.6%), or should receive a direct financial reward (10.1%). For non-directed donation, 23.5%, 55.6%, and 20.7% were not in support of reward, compensation only, and financial reward, respectively. While live kidney donation was accepted by the majority of individuals surveyed, only the minority approved of commercialization. © 2011 John Wiley & Sons A/S.

    Full Text Available OBJECTIVE: Report the authors’ initial experience with hand-assisted laparoscopic nephrectomy technique in renal donors for transplantation. MATERIALS AND METHODS: Twenty-seven donors submitted to hand-assisted laparoscopic nephrectomy were retrospectively analyzed from February 2001 to June 2002. Technical aspects of the donor surgery, results, and complications, are discussed, as well as recipient’s complications and outcomes. RESULTS: Among 27 hand-assisted laparoscopic nephrectomies, left kidney was withdrew in 18 donors (66.6%, and right kidney in 9 (33.3%. The operative time ranged from 55 to 210 minutes (mean 132.7 ± 37.6 min, and the time of hot ischemia ranged from 2 to 11 minutes (mean 4.7 ± 2.5 min, with an estimated mean blood loss during the intraoperative period of 133.3 mL. Conversion to open surgery was necessary for 1 (3.7% patient due to vascular lesion. In graft evaluation, immediate diuresis was observed in 26 (96.3% cases, and mean serum creatinine in PO day 7 was 1.5 ± 1.1 mg/dL. Renal vein thrombosis occurred in 1 (3.7% patient requiring graft removal. Lymphocele was observed in 3 recipients (11.1%, and urinary leakage due to ureteral necrosis in 1 case (3.7%. CONCLUSION: Hand-assisted laparoscopic nephrectomy in living donors is a safe procedure and an effective alternative to open nephrectomy. In this series, the procedure presented low morbidity after surgery providing to the recipient a good morphological and functional quality of the graft.

    Full Text Available Purpose: To retrospectively review anesthesia and intensive care management of 145 consented volunteers subjected to right lobe or left hepatectomy between 2003 and 2011. Methods: After local ethics committee approval, anesthetic and intensive care charts, blood transfusion requirements, laboratory data, complications and outcome of donors were analyzed. Results: One hundred and forty-three volunteers successfully tolerated the surgery with no blood transfusion requirements, but with a morbidity rate of (50.1%. The most frequent complication was infection (21.1% (intraabdominal collections, followed by biliary leak (18.2%. Two donors had major complications: one had portal vein thrombosis (PVT treated with vascular stent. This patient recovered fully. The other donor had serious intraoperative bleeding and developed postoperative PVT and liver and renal failure. He died after 12 days despite intensive treatment. He was later reported among a series of fatalities from other centers worldwide. Epidural analgesia was delivered safely (n=90 with no epidural hematoma despite significantly elevated prothrombin time (PT and international normalization ratio (INR postoperatively, reaching the maximum on Day 1 (16.9±2.5 s and 1.4±0.2, P<0.05 when compared with baseline. Hypophosphatemia and hypomagnesemia were frequently encountered. Total Mg and phosphorus blood levels declined significantly to 1.05±0.18 mg/dL on Day 1 and 2.3±0.83 mg/dL on Day 3 postoperatively. Conclusions: Coagulation and electrolytes need to be monitored perioperatively and replaced adequately. PT and INR monitoring postoperatively is still necessary for best timing of epidural catheter removal. Live donor hepatectomy could be performed without blood transfusion. Bile leak and associated infection of abdominal collections requires further effort to better identify biliary leaks and modify the surgical closure of the bile ducts. Donor hepatectomy is definitely not a complication

    With the decrease in the average donor age and the increase in the proportion of female donors, both donor safety and cosmetic appearance are major concerns for some living donors in living donor liver transplantation (LDLT) because a large abdominal incision is needed that may influence the donor's quality of life. In all, 429 donors who underwent donor hepatectomy for LDLT from April 2010 to February 2013 were included in the study. Donors were divided into 3 groups based on the type of incision: conventional inverted L incision (n = 268; the C group), upper midline incision (n = 147; the M group), and transverse incision with laparoscopy (n = 14; the T group). Demographics, perioperative outcomes, postoperative complications for donors and recipients, and questionnaire-derived donor satisfaction with cosmetic appearance were compared. The mean age was lower (P self-confidence were noted in the M and T groups versus the C group. In conclusion, the use of a minimal incision is technically feasible for some donor hepatectomy cases with a favorable safety profile. The patient satisfaction levels were greater with improved cosmetic outcomes in cases of minimal incision versus cases of conventional incision.

    Organ donation during life is an act of great altruism, with unique family, social, economic, and psychological impacts. The group of anesthesiologists involved in this program sought to assess the degree of satisfaction among kidney donors between 2007 and 2008 and, in particular, with the anesthetic approach. A telephone survey of kidney donors in 2007 and 2008 complemented a retrospective evaluation of the records of the Acute Pain Unit. Among 32 kidney donors, 2 were excluded as impossible to contact. Their mean age was 44.33 years including 60% women. The degree of relationship was fathers (43.3%), siblings (50%) or spouses (6.7%). Donors who underwent outpatient anesthesia were satisfied (40%) or very satisfied (60%) with the information received, all willing to repeat the experience of kidney donation. The positive aspects were: good reception (83.4%), help to a family member (30%), good information (13.3%), and confidence in the team (6.6%). No downside was mentioned by 50% of donors. Postoperative analgesia was performed using an epidural catheter (93.3%) or patient-controlled analgesia with morphine (6.7%) associated with intravenous paracetamol in all cases. With regard to analgesia using an epidural catheter, the mean total dose of morphine was 7.7 mg and 27.4 mg for 0.2% ropivacaine over an average of 3.32 days. Pain was assessed in the first 24 hours postoperatively using a scale ranging from 0 (no pain) to 4 (unbearable pain): 30% reported 0; 60% 1; and 10% 2. The complaints were pruritus (40%), nausea/vomiting (16.7%), constipation (6.7%) and/or urinary retention (3.3%). No donor showed an altered state of consciousness, motor block, or paresthesias. Living kidney donors showed a high degree of overall satisfaction. The anesthesia consultation was extremely helpful with a positive impact on kidney donation. An epidural catheter for analgesia after surgery proved to be effective and appropriate for this type of procedure. Copyright © 2011 Elsevier

    Donor shortage for kidney transplantation may increase the number of expanded-criteria living donors (ECLDs). We investigated recent trends for ECLD use and the long-term outcomes of living kidney donors. We retrospectively analyzed medical records of 1,144 living kidney donors who donated at the Seoul National University Hospital from 1993 to 2015. The expanded criteria for living donation allow the following: age ≥60 years, body mass index >30 kg/m(2), history of hypertension, estimated glomerular filtration rate 100 mg/dL. The mean age of donors was 40.7 ± 10.8 years, and there were 600 women (52.4%). A total of 466 donors (40.7%) met the ECLD criteria, and the proportion of ECLDs increased over time. Only 5 donors died after donation over a median follow-up of 7 years. No donor developed end-stage renal disease (ESRD). A urine protein-creatinine ratio ≥0.3 g/gCr was found in 14 patients and was more common in the ECLDs than in the standard-criteria living donors. The follow-up loss rate of donors was 59.3% at 5 years. Both mortality and ESRD were very rare in carefully selected living kidney donors. However, living donors should be followed more carefully, because the follow-up loss rate was very high and ECLDs are increasingly used. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Hepatitis B virus (HBV genotype appears to show varying geographic distribution. Molecular epidemiological study of HBV in particular areas in Indonesia is still limited. This study was aimed to identify the prevalence of HBV genotype/subgenotype and mutations in basal core promoter (BCP region in voluntary blood donors in Makassar, one of the biggest cities in east part of Indonesia. A total of 214 hepatitis B surface antigen (HBsAg-positive samples were enrolled in this study. HBV genotype/subgenotype was identified by genotype-specific PCR method or direct sequencing of pre-S region. Mutations in BCP were identified by direct sequencing of the corresponding region. Results HBV/B and HBV/C were detected in 61.21% and 25.23% of the samples, while mix of HBV/B and HBV/C was found in 12.62% of the samples. Based on pre-S region, among HBV/B and HBV/C, HBV/B3 (95.00% and HBV/C1 (58.82% were predominant. Interestingly, HBV/D was identified in two samples (22.165.07 and 22.252.07. Complete genome sequences of two HBV/D strains (22.165.07 and 22.252.07 demonstrated that both strains belong to HBV/D6, and the divergence between the two strains were 1.45%, while divergences of both 22.165.07 and 22.252.07 strains with reference strain (AM422939/France were 2.67%. A1762T/G1764A mutation was observed in 1.96% and 5.36%, whereas T1753V mutation was found in 2.94% and 1.79% of HBV/B and HBV/C, respectively. Conclusion HBV/B and HBV/C are dominant in Makassar, similar to most areas in Indonesia. Mutations in BCP which might be associated with severity of liver disease are less common.

    Previous studies have shown substantial geographical variation in blood donation within developed countries. To understand this issue better, we identified community characteristics associated with blood donor rates in German municipalities in an ecological analysis. We calculated an aggregated rate of voluntary blood donors from each of 1533 municipalities in south-west Germany in 2007 from a database of the German Red Cross Blood Service. A multiple linear regression model estimated the association between the municipality-specific donor rate and several community characteristics. Finally, a spatial lag regression model was used to control for spatial autocorrelation that occurs when neighbouring units are related to each other. The spatial lag regression model showed that a relatively larger population, a higher percentage of inhabitants older than 30 years, a higher percentage of non-German citizens and a higher percentage of unemployed persons were associated with lower municipality-specific donor rates. Conversely, a higher donor rate was correlated with higher voter turnout, a higher percentage of inhabitants between 18 and 24 years and more frequent mobile donation sites. Blood donation appears to be a highly clustered regional phenomenon, suggesting the need for regionally targeted recruiting efforts and careful consideration of the value of mobile donation sites. Our model further suggests that municipalities with a decreasing percentage of 18- to 24-year-olds and an increasing percentage of older inhabitants may experience substantial declines in future blood donations. © 2011 The Author(s).

    Full Text Available We report a case of renal transplantation using a horseshoe kidney from a living, genetically unrelated donor. The recipient was a 60-year-old man with diabetic nephropathy, and the donor was the 63-year-old wife of the recipient with a horseshoe kidney free of complications. Computed tomography showed two renal arteries and one renal vein on the left side, and the isthmus was perfused by several accessory arteries and veins. To demarcate the boundary of the isthmus, the left renal artery was ligated and cannulated for in situ perfusion. Furthermore, the isthmus was clamped, and the boundary of the isthmus was confirmed. The kidney was divided at the left margin of the perfused boundary. The cut ends of the isthmus were closed by sutures. The left kidney was transplanted into the right iliac fossa of the recipient. Asymptomatic fluid collection occurred on the cut surface at the isthmus of the donor, and this fluid decreased in due course. On the other hand, the recipient experienced no surgical complication or rejection, while maintaining serum creatinine levels of 2.00–2.20 mg/dL over a 22-month follow-up period. Horseshoe kidneys may be used for transplantation in selected cases after a detailed preoperative evaluation.

    To minimize the health risks faced by living kidney donors, multiple clinical practice guidelines have been developed on the assessment and care of potential donors. This study aims to compare the quality, scope, and consistency of these guidelines. We searched for guidelines on living kidney donation in electronic databases, guideline registries, and relevant Web sites to February 21, 2011. Methodological quality was assessed using the Appraisal of Guidelines for Research and Education (AGREE) instrument. Textual synthesis was used to compare guideline recommendations. Ten guidelines, published from 1996 to 2010, were identified. Although generally comprehensive, scope varied considerably and mostly appeared to lack methodological rigor. Many recommendations were consistent, but important differences were evident, particularly for thresholds for comorbidities which precluded donation; obesity/overweight (body mass index, 30-35 kg/m), diabetes/prediabetes (fasting blood glucose level, 6.1-7.0 mmol/L and oral glucose tolerance test, 7.8-11.1 mmol/L), hypertension (130/85 to 140/90 mm Hg), cardiovascular disease, malignancy, and nephrolithiasis. The importance of informed voluntary consent, genuine motivation, support, and psychological health were recognized but difficult to implement as specific tools for conducting psychosocial assessments were not recommended. Multiple major guidelines for living kidney donation have been published recently, resulting in unnecessary duplicative efforts. Most do not meet standard processes for development, and important recommendations about thresholds for exclusion based on comorbidities are contradictory. There is an urgent need for international collaboration and coordination to ensure, where possible, that guidelines for living donation are consistent, evidence based, and comprehensive to promote best outcomes for a precious resource.

    Kidney transplantation is the preferred option for patients with end-stage renal disease facing the need for dialysis because it provides maximum survival benefit. The number of people seeking kidney transplantation greatly exceeds available deceased donor organs. Organs from live donors provide a survival advantage over organs from deceased donors while also broadening the pool of available organs. The purpose of this review is to discuss the clinical guidelines that pertain to live kidney organ donation and to describe the nutrition evaluation and care of live kidney donors. The process for living kidney donation is dictated by policies centered on protecting the donor. In a perfect world, the living donor would present with a flawless medical examination and a benign family health history. The obesity epidemic has emerged as a major health concern. Live donor programs are faced with evaluating increasing numbers of obese candidates. These "medically complex donors" may present with obesity and its associated comorbid conditions, including hypertension, impaired glycemic control, and kidney stone disease. The dietitian's role in the live donor program is not well defined. Participation in the living donor selection meeting, where details of the evaluation are summarized, provides a platform for risk stratification and identification of donors who are at increased lifetime risk for poor personal health outcomes. Guiding the donor toward maintenance of a healthy weight through diet and lifestyle choices is a legitimate goal to minimize future health risks.

    To define the changes in liver and spleen volumes in the early postoperative period after partial liver donation for living-donor liver transplantation (LDLT) and to determine factors that influence liver and spleen volume changes. 27 donors who underwent partial hepatectomy for LDLT were included in this study. The rates of liver and spleen volume change, measured with CT volumetry, were correlated with several factors. The analyzed factors included the indocyanine green (ICG) retention rate at 15 minutes after ICG administration, preoperative platelet count, preoperative liver and splenic volumes, resected liver volume, resected-to-whole liver volume ratio (LV{sub R}/LV{sub W}), resected liver volume to the sum of whole liver and spleen volume ratio [LV{sub R}/(LV{sub W} + SV{sub 0})], and pre and post hepatectomy portal venous pressures. In all hepatectomy donors, the volumes of the remnant liver and spleen were increased (increased rates, 59.5 ± 50.5%, 47.9 ± 22.6%). The increment rate of the remnant liver volume revealed a positive correlation with LV{sub R}/LV{sub W} (r = 0.759, p < 0.01). The other analyzed factors showed no correlation with changes in liver and spleen volumes. The spleen and remnant liver volumes were increased at CT volumetry performed 2 weeks after partial liver donation. Among the various analyzed factors, LV{sub R}/LV{sub W} influences the increment rate of the remnant liver volume.

    Abstract Introduction: Antiphospholipid syndrome (APS), autoantibodies directed against phospholipid-binding proteins are associated with cause vascular thrombosis. Patients with APS requiring renal transplantation are at risk of early graft loss due to arterial or venous thrombosis, or thrombotic microangiopathy (TMA). Here, we report 3 cases of successful renal transplantation in patients with APS. Clinical Findings: A 53-year-old man with end-stage renal disease (ESRD) had experienced bilateral deep venous thrombosis (DVT) in the lower extremities 16 years ago and was administered warfarin. However, he frequently experienced recurrent DVT despite of anticoagulation therapy. Before the surgery, APS was confirmed based on positive results lupus anticoagulant in serological tests. A 40-year-old man with polycystic kidney disease and a history recurrent DVT tested positive for lupus anticoagulant and anticardiolipin antibodies. Lastly, a 42-year-old woman with ESRD was diagnosed with APS 7 years ago. She also developed DVT and tested positive for lupus anticoagulant and anti-B2-glycoprotein 1. The anticoagulation protocol was as follows in all cases: Warfarin was stopped 5 days before living donor renal transplantation and intravenous heparin therapy was started. During surgery, bolus heparin injections (3000 U) were administered to prevent arterial or venous thrombosis. Heparin was substituted with warfarin on postoperative day 4. The third patient (42/F) developed clinical rejection indicated by increased serum creatinine levels and donor-specific antibodies (DSA) and received steroid pulse therapy, plasmapheresis, and rituximab. This treatment restored graft function to within the normal range. The latest graft function in all patients was maintained at normal levels in the outpatient clinic. Conclusions: Living donor renal transplantation may be successful in patients with APS following perioperative anticoagulation therapy. However, because of the high risk of

    This study was done to know the distribution and frequencies of blood groups among blood donors attending voluntary blood donation camps organized by the Rajendra Institute of Medical Sciences (RIMS), Ranchi, Jharkhand so that demand and supply ratio of the four blood groups can be maintained so that no patient dies due to lack of a particular blood group. Up till now about 400 red cells antigen have been identified. The majority follow Mendelian inheritance. The ABO and Rhesus (Rh) blood group system are most important for blood transfusion purposes, parental testing, legal medicine, and in population genetic study. This study was conducted to determine and compare the frequency and distribution of ABO and Rh blood groups among voluntary blood donors attending blood donation camps in Jharkhand organized by RIMS. The aim is to know the demand and supply ratio of a particular blood group in light of their distribution in the society so that no patient dies due to the deficient supply of blood. It is a retrospective study carried out at blood bank. Materials and Methods: A study was conducted at Blood bank, RIMS, Ranchi, Jharkhand, over a period of 4 years from January 1, 2012, to December 31, 2015. Blood group of the blood donors was determined by commercially available standard monoclonal antisera by test tube agglutination technique accompanied by reverse grouping. Out of 20,455 subjects, 18,717 (91.73%) were male and 1738 (8.27%) were female subjects. The ABO blood group present was B (35.15%) followed by O (34.73%), A (22.09%), and AB (8.03%) in blood donors while in Rh system, (96.46%) donors were Rh +ve and (3.54%) donors were Rh -ve. The study has a significant implication regarding the inventory management of blood bank and transfusion services for the indoor patients of RIMS and for emergency supply to other hospitals of Jharkhand in dire need of blood. The knowledge of distribution of blood group is very important for blood banks and transfusion services

    Living-donor kidney and liver transplantation intend to improve pediatric recipients' psychosocial well-being, but psychosocial impact in recipients strongly depends upon the impact on the donor and the quality of family relations. We systematically reviewed quantitative and qualitative studies addressing the psychosocial impact of pediatric living-donor kidney and liver transplantation in recipients, donors, and the family. In accordance with the PRISMA guidelines, we systematically searched the databases Medline, Web of Knowledge, Cinahl, Embase, ERIC, and Google Scholar. We identified 23 studies that satisfied our inclusion criteria. Recipients had improved coping skills and satisfactory peer relationships, but also reported anxiety and depressive symptoms, worried about the future, and had a negative body image. Similarly, donors experienced increased self-esteem, empowerment, and community awareness, but also complained of postoperative pain and a lack of emotional support. With respect to family impact, transplantation generated a special bond between the donor and the recipient, characterized by gratitude and admiration, but also raised new expectations concerning the recipient's lifestyle. As psychological problems in recipients were sometimes induced by feelings of guilt and indebtedness toward the donor, we recommend more research on how gift exchange dynamics function within donor-recipient relationships, enrolling donors and recipients within the same study.

    AIM: To evaluate the safety of donors in adult living donor liver transplantation (LDLT) using the right lobe in a single liver transplantation center in China.METHODS: We investigated retrospectively 52 living donor liver resections performed from October 2003 to July 2006. All patients were evaluated by blood tests and abdominal CT. The mean donor age was 28.2±7.4years. Residual liver volume was 42.1%±4.7%. Mean operative time was 420±76.2 min; mean ICU stay, less than 36 h; mean hospital stay, 16.4±8.6 d; and mean follow-up period, 6 mo.RESULTS: There was no mortality. The overall complication rate was 40% (21 donors). Major complications included biliary leak in two, and pneumonia in 2 donors. Minor complications included mild pleural effusion in 12 donors, transient ascites in 6, mild depression in 4, intra-abdominal collections in 2,and wound infections in 1 donor. Residual liver volume did not affect the complication rate. None required reoperation. Return to pre-donation activity occurred within 5-8 wk.CONCLUSION: Right hemi-hepatectomy can be performed safely with minimal risk in cases of careful donor selection. Major complications occurred in only 7.7% of our series.

    Deceased donor (DDLT) and living donor (LDLT) liver transplant (LT) is in vogue in several centers in India. Most centers are resorting to LDLT as a preferred surgery due to shortage of deceased donor liver. The risk of infection and its effect on survival in both groups of recipients from the Indian subcontinent are not known. The study was conducted to compare the bacterial infection rates among LDLT and DDLT recipients and their impact on survival at a tertiary referral center. Retrospective data on 67 LT recipients were reviewed. Data on pre-, per-, and postoperative bacterial infection rates and the common isolates were obtained. Thirty-five patients had LDLT and 32 had DDLT. The prevalence of pre-operative bacterial infection and the isolates was similar in both groups. The perioperative bacterial infection rates were significantly higher in DDLT recipients (P urinary tract followed by bloodstream infection. The common bacterial isolates in either transplant were Klebsiella followed by Escherichia coli, Pseudomonas spp. and nonfermenting gram-negative bacteria. Six patients (four LDLT; two DDLT) were treated for tuberculosis. Among the risk factors, cold ischemic time, and duration of stay in the intensive care unit was significantly higher for DDLT (p < 0.01). The death rates were not significantly different in the two groups. However, the odds for death were significantly high at 26.8 (p < 0.05) for postoperative bacterial infection and 1.8 (p < 0.001) for past alcohol. Liver transplant recipients are at high-risk for bacterial infection irrespective of type of transplant, more so in DDLT.

    Liver transplantation is the only curative treatment known to date for end-stage liver disease occurring as a result of primary sclerosing cholangitis (PSC). Here, we report a case in which living donor liver transplantation (LDLT) for PSC was cancelled because of histological abnormalities in intraoperative biopsy of the donor liver. The donor was the mother of the recipient, and her preoperative evaluation revealed no abnormalities. In the donor operation, the donor liver biopsy revealed expansion of the portal zone with lymphocytic infiltration and dense concentric fibrosis developed around a bile duct. These histological findings were identical to those of early-stage PSC; therefore, the LDLT was called off. The experience in this case suggests that preoperative liver biopsy may be useful to exclude first-degree relative donors with potential PSC prior to LDLT for PSC.

    BACKGROUND: Donor shortage is the biggest obstacle in organ transplantation. Living donor liver transplantation (LDLT) has been considered as a valuable approach to short-ening waiting time. The objectives of this study were to inves-tigate the feasibility of utilizing donors older than 50 years in LDLT and to evaluate the graft function and recipient survival. METHODS: All LDLT cases (n=159) were divided into the older (donor age ≥50 years, n=10) and younger (donor age RESULTS: The median donor age was 58.5 (52.5-60.0) years in the older donor group and 25.0 (23.0-32.0) in the younger do-nor group. There was no significant difference in cold ischemic time, anhepatic phase and operation time between the older and younger donor groups (P>0.05). However, the volume of red blood cell transfused in operation was greater in the older donor group than in the younger donor group (1900 vs 1200 mL, P=0.023). The 1-, 3- and 5-year graft survival rates were 90%, 80% and 80% for the older donor group, and 92%, 87%and 87% for the younger donor group, respectively (P=0.459). The 1-, 3- and 5-year survival rates were 100%, 90% and 90%for recipients with older grafts, and 93%, 87% and 87% for those with younger grafts, respectively (P=0.811). CONCLUSION: It is safe for a LDLT recipient to receive liver from donors older than 50 years, and there is no significant adverse effect on graft function and long-term patients' survival.

    With the increasing prevalence of living-donor liver transplantation(LDLT) for patients with hepatocellular carcinoma(HCC),some authors have reported a potential increase in the HCC recurrence rates among LDLT recipients compared to deceased-donor liver transplantation(DDLT) recipients.The aim of this review is to encompass current opinions and clinical reports regarding differences in the outcome,especially the recurrence of HCC,between LDLT and DDLT.While some studies report impaired recurrence- free survival and increased recurrence rates among LDLT recipients,others,including large database studies,report comparable recurrence- free survival and recurrence rates between LDLT and DDLT.Studies supporting the increased recurrence in LDLT have linked graft regeneration to tumor progression,but we found no association between graft regeneration/initial graft volume and tumor recurrence among our 125 consecutive LDLTs for HCC cases.In the absence of a prospective study regarding the use of LDLT vs DDLT for HCC patients,there is no evidence to support the higher HCC recurrence after LDLT than DDLT,and LDLT remains a reasonable treatment option for HCC patients with cirrhosis.

    A case of severe autoimmune hemolytic anemia after ABO matched living donor liver transplantation. We present here a case of severe autoimmune hemolytic anemia after ABO matched living donor liver transplantation. The patient is 56 y.o male. He received living donor liver transplantation from his ABO matched son in May 2007. In July, he was suffered from a progressive anemia, and diagnosed as autoimmune hemolytic anemia by the laboratory examinations. Intensive treatment including predonisolone, azathiopurine, rituximab, plasma exchange, was given, however, the disease was resistant to the treatment. By the administration of cyclophosphamide combined with rituximab, remission was finally achieved. To date, immune mediated hemolytic anemia after ABO matched living donor liver transplantation has not been reported, although several cases of ABO mismatched living donor liver transplantation have been reported. His severe but transient clinical course of anemia suggests that the transient emergence of donor lymphocytes may be responsible for onset of hemolytic anemia.

    2009-01-01

    Donor advocacy is a critical feature of live donor transplantation. Donor Advocates and Donor Advocate Teams (DAT) are now routine to the practice of live donor evaluation in the USA. Multidisciplinary in nature, DATs gather both medical and psychosocial information about potential live organ donors and then render a decision as to whether or not these individuals are suitable to participate. Because of the critical ethical and psychosocial concerns about live donation, thorough donor evaluations are essential. Additionally, the information gathered must be accurate, and this requires honest disclosure by the donor candidate. In this paper, we describe how DATs can use various forms of free, public content available on the Internet to aid live donor assessments. In this way, the DAT assumes somewhat of an investigative role; however, this is ethically justified in light of the DAT duty to protect the donor. The protective effect can also spread to the transplant program, in general, when inappropriate donors are excluded from the donation process.

    Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

    A decrease in live donor pediatric kidney transplants has occurred in the United States. This study investigates barriers that may influence access to live donor kidney transplants in children. Retrospective chart review was conducted for 91 children (69% male, mean age 11.9 years) who underwent pretransplant workup from 2005 to 2015 at an urban pediatric hospital. Fifty-four percent were African American, 32% Caucasian, 8% Arabic, 3% Hispanic, and 3% Others. Government-sponsored insurance (Medicaid/Medicare) was utilized by 73%, and 54% had dual caregivers. Only nine of 68 kidney transplants were live donor transplants. Live donor transplants (11%) were significantly (P=.008) lower than deceased donor transplants (59%) in African Americans. Private insurance was reported by 56% of live donor recipients and 25% of deceased donor recipients. Among live donor recipients, 78% were from dual caregiver families. Caregiver, health-related, financial, and religious/cultural barriers to live donor transplants were reported, several of which may be amenable to positive intervention.

    The present investigation aims to evaluate the prevalence of IgM and IgG anti-T. gondii antibodies and the associated risk factors among healthy blood donors in Mashhad city, Razavi Khorasan province, Iran. We screened a total of 500 serum samples by census method from apparently healthy blood donors of the Mashhad Blood Transfusion Organization (MBTO) for IgG and IgM anti-T. gondii antibodies by enzyme linked immunosorbent assay (ELISA). We found that 29.6%, 25%, 1.4%, and 3.2% of tested donors were positive for anti-T. gondii antibodies, only IgG antibody, both IgM and IgG, and IgM antibody alone, respectively. Several risk factors which were significantly related to T. gondii seropositivity in the univariate analysis at P sausage/hot dog consumption (OR = 4.472, P < 0.001). The results of this study can be a warning for blood transfusion organizations to pay special attention to toxoplasmosis among blood donors and also design screening programs for prevention of transfusion-transmitted toxoplasmosis.

    Cognitions surrounding living organ donation, including the motivation to donate, expectations of donation and worries about donation, are relevant themes during living donor evaluation. However, there is no reliable psychometric instrument assessing all these different cognitions. This study developed and validated a questionnaire to assess pre-donation motivations, expectations and worries regarding donation, entitled the Donation Cognition Instrument (DCI). Psychometric properties of the DCI were examined using exploratory factor analysis for scale structure and associations with validated questionnaires for construct validity assessment. From seven Dutch transplantation centres, 719 potential living kidney donors were included. The DCI distinguishes cognitions about donor benefits, recipient benefits, idealistic incentives, gratitude and worries about donation (Cronbach's alpha 0.76-0.81). Scores on pre-donation cognitions differed with regard to gender, age, marital status, religion and donation type. With regard to construct validity, the DCI was moderately correlated with expectations regarding donor's personal well-being and slightly to moderately to health-related quality of life. The DCI is found to be a reliable instrument assessing cognitions surrounding living organ donation, which might add to pre-donation quality of life measures in facilitating psychosocial donor evaluation by healthcare professionals.

    Background Living donor kidney transplantation is becoming popular in China,whereas,in clinical situations,some kidney donors may be sub-optimal,namely marginal living donor.The present study aimed to evaluate the safety and efficacy of marginal living donor kidney transplantation in a Chinese single center.Methods Between January 2001 and December 2009,888 kidney transplantations were performed in our center; 149were living donor kidney transplantations.The living donors and recipients were followed up regularly after the operation.Of the living donors,30 donors were marginal,who were older than 60 years or suffered from kidney anomaly or some benign diseases.Among the non-marginal living kidney transplantations,58 donors and recipients had complete perioperative and follow-up data.We compared the marginal and non-marginal living donor kidney transplantations with regard to donor age,follow-up period,donor's serum creatinine at the last follow-up,recipient's serum creatinine at the last follow-up,and graft survival at the last follow-up.Results The mean age of donors in the marginal and non-marginal living donors were (55±9) (37-66) and (43±12) (30-59) years.The mean follow-up times of the marginal and non-marginal groups were (26.4±13.4) months and (28.8±14.8)months.The donor and recipient serum creatinine levels at the last follow-up were (1.16±0.20) mg/dl and (1.30±0.24) mg/dl in the marginal group,and (1.12±0.32) mg/dl and (1.34±0.32) mg/dl in the non-marginal group.Three recipients in the marginal group and five recipients in the non-marginal group had acute rejection episodes during the first year.Actuarial 3-year graft survival was 96.7% in the marginal group and 100% in the non-marginal group.No significant differences were detected between the two groups with regard to these data.Conclusion Utilization of highly selective marginal living donors can be a safe,feasible,and effective way for the treatment of patients with end stage renal disease.

  11. On harm thresholds and living organ donation: must the living donor benefit, on balance, from his donation?

    Williams, Nicola Jane

    2017-05-19

    For the majority of scholars concerned with the ethics of living organ donation, inflicting moderate harms on competent volunteers in order to save the lives or increase the life chances of others is held to be justifiable provided certain conditions are met. These conditions tend to include one, or more commonly, some combination of the following: (1) The living donor provides valid consent to donation. (2) Living donation produces an overall positive balance of harm-benefit for donors and recipients which cannot be obtained in a less harmful manner. (3) Donation is not liable to cause significant and long-term morbidity to, or the death of, the donor. This paper critically examines the suggestion that these criteria are not sufficient to offer a general account of justified living organ donation in the context of competent volunteers and that key to justified living organ donation is that donors receive sufficient benefits from their donation that these outweigh the harms they suffer. However, although this view-termed here 'The Donor Benefit Standard'-directs welcome attention to the many and complex motives which may underlie living organ donation, this paper ultimately concludes that given the threats this position poses to individual autonomy and the lives of those in need of organ transplants 'The Donor Benefit Standard' should ultimately be rejected.

    Insufficient is the evidence for safe use of elderly donors in adult-to-adult living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcomes of right lobe LDLT by donor age (≥55 vs. 55 years). All living donors who underwent right hepatectomy at the authors' institution between March 2008 and December 2015 were divided into 2 groups: group A with an age ≥ 55 and group B with an age 55. The selection criteria for elderly donor were preservation of middle hepatic vein, remnant liver volume ≥30%, and no or mild fatty liver. The matching criteria of recipients for the elderly donor grafts were model for end-stage liver disease score0.8%, and body mass index55 years without compromising donor safety or recipient outcomes.

    AIM: To retrospectively evaluate the management and outcome of venous obstruction after living donor liver transplantation (LDLT).METHODS: From February 1999 to May 2009, 1 intraoperative hepatic vein (HV) tension induced HV obstruction and 5 postoperative HV anastomotic stenosis occurred in 6 adult male LDLT recipients. Postoperative portal vein (PV) anastomotic stenosis occurred in 1 pediatric left lobe LDLT. Patients ranged in age from 9 to 56 years (median, 44 years). An air balloon was used to correct the intraoperative HV tension. Emergent surgical reoperation, transjugular HV balloon dilatation with stent placement and transfemoral venous HV balloon dilatation was performed for HV stenosis on days 3, 15, 50, 55, and 270 after LDLT, respectively. Balloon dilatation followed with stent placement via superior mesenteric vein was performed for the pediatric PV stenosis 168 d after LDLT.RESULTS: The intraoperative HV tension was corrected with an air balloon. The recipient who underwent emergent reoperation for hepatic stenosis died of hemorrhagic shock and renal failure 2 d later. HV balloon dilatation via the transjugular and transfemoral venous approach was technically successful in all patients. The patient with early-onset HV stenosis receiving transjugular balloon dilatation and stent placement on the 15th postoperative day left hospital 1 wk later and disappeared, while the patient receiving the same interventional procedures on the 50th postoperative day died of graft failure and renal failure 2 wk later. Two patients with late-onset HV stenosis receiving balloon dilatation have survived for 8 and 4 mo without recurrent stenosis and ascites, respectively. Balloon dilatation and stent placement via the superior mesenteric venous approach was technically successful in the pediatric left lobe LDLT, and this patient has survived for 9 mo without recurrent PV stenosis and ascites.CONCLUSION: Intraoperative balloon placement, emergent reoperation, proper

    Living organ donation involves significant out-of-pocket costs, which burden donor candidates and may be an obstacle to donation. There is a single US grant (the National Living Donor Assistance Center-NLDAC) to cover live donor travel costs. Although there may be center-specific variability in grant utilization, prospective donors-and their intended recipients-must also meet eligibility criteria. In fact, the NLDAC grant is used by 300% of the federal poverty level) (n=51; 82%). The remaining exclusions (n=11; 18%) included being a nondirected donor, not meeting residency requirements, and "other." Expanding NLDAC eligibility criteria-by broadening the recipient means test or by taking steps to eliminate it from the NLDAC charter-would reduce financial burdens associated with live donation. © 2016 John Wiley & Sons A/S.

    2014-01-01

    Full Text Available As Laparoscopic Donor Nephrectomy (LDN offers several advantages for the donor such as lesser post-operative pain, fewer cosmetic concerns and faster recovery time, there is growing global trend towards LDN as compared to open nephrectomy. Comprehensive pre-LDN donor evaluation includes assessment of renal morphology including pelvi-calyceal and vascular system. Apart from donor selection, evaluation of the regional anatomy allows precise surgical planning. Due to limited visualization during laparoscopic renal harvesting, detailed pre-transplant evaluation of regional anatomy, including the renal venous anatomy is of utmost importance. MDCT is the modality of choice for pre-LDN evaluation of potential renal donors. Apart from appropriate scan protocol and post-processing methods, detailed understanding of surgical techniques is essential for the Radiologist for accurate image interpretation during pre-LDN MDCT evaluation of potential renal donors. This review article describes MDCT evaluation of potential living renal donor, prior to LDN with emphasis on scan protocol, post-processing methods and image interpretation. The article laid special emphasis on surgical perspectives of pre-LDN MDCT evaluation and addresses important points which transplant surgeons want to know.

    Full Text Available PURPOSE: To compare hand-assisted laparoscopic donor nephrectomy and pure laparoscopic live donor nephrectomy techniques in live donor nephrectomy. METHODS: In this retrospective study, we included all patients submitted to hand-assisted laparoscopic donor nephrectomy and pure laparoscopic live donor nephrectomy between May 2002 and December 2007. The operative data and post-operative courses were reviewed. Information was collected on the operative time, warm ischemia time, estimated blood loss, intra-operative complications, time to first oral intake, length of hospital stay, and post-operative complications. The data were analyzed using Student's t -tests and Fisher exact tests as appropriate, with statistical significance defined as p < 0.05. RESULTS: The means of the operative duration, warm ischemia time and intra-operative bleeding were 83 min, 3.6 min and 130.9 cc, respectively, for hand-assisted laparoscopic donor nephrectomy, and 78.4 min, 2.5 min and 98.9 cc, respectively, for pure laparoscopic live donor nephrectomy (p=0.29, p<0.0001 and p=0.08, respectively. Intra-operative complications occurred in 6% of patients submitted to hand-assisted laparoscopic donor nephrectomy and in 4.5% of those submitted to pure laparoscopic live donor nephrectomy (p=0.68. Only one patient from each group required conversion to open surgery; one person receiving hand-assisted laparoscopic donor nephrectomy had bleeding and one person receiving pure laparoscopic live donor nephrectomy had low carbon dioxide levels during the warm ischemia period.

    Full Text Available Abstract Introduction Selecting a marginal donor in liver transplantation (LT remains controversial but is necessary because of the small number of available donors. Case presentation A 46-year-old Japanese woman was a candidate to donate her liver to her brother, who had decompensated liver cirrhosis of unknown origin. Eight years before the donation, she had a mild liver dysfunction that was diagnosed as a hepatitis C virus (HCV infection (serotype 2. She had received anti-viral therapy with interferon α-2b three times weekly for 24 weeks and had a sustained viral response (SVR. A biopsy of her liver before the donation showed normal findings without any active hepatitis, and her serum was negative for HCV-RNA. Only 67 patients have undergone LT from a cadaveric donor in Japan. The family in this case decided to have living donor LT. A careful selection for the liver graft donation was made; however, since she was the only candidate, we approved her as a living donor. She was discharged nine days after the liver donation. Her liver function recovered immediately. A computed tomography scan showed sufficient liver regeneration one year later. Her brother also had good liver function after LT and had no HCV infection 48 months after surgery and no de novo malignancy. Neither of the siblings has developed an HCV infection. Conclusions A patient with SVR status after interferon therapy might be considered a candidate for living donor LT but only if there are no other possibilities of LT for the recipient. A careful follow-up of the donor after donation is needed. The recipient also must have a very close follow-up because it is difficult to predict what might happen to the graft with post-transplant immunosuppression.

    BACKGROUND: Living donor liver transplantation (LDLT) has recently emerged as an effective therapeutic alternative for patients with end-stage liver disease. In the meantime, the health-related quality of life (HRQoL) of the donors is becoming better appreciated. Here we aimed to review the current literature and summarize the effects of liver donation on the long-term HRQoL of living donors. DATA SOURCES: A literature search of PubMed using "donors","living donor liver transplantation", "health-related quality of life", and "donation" was performed, and all the information was collected. RESULTS: The varied postoperative outcomes of liver donors are attributive to the different evaluation instruments used. On the whole, donors experienced good long-term physical and mental well-being with a few complaining of compromised quality of life due to mild symptoms or psychiatric problems. The psychosocial dimension has received increasing attention with the vocational, interpersonal and financial impact of liver donation on donors mostly studied. CONCLUSIONS: Generally, donors have a good HRQoL after LDLT. Nevertheless, to achieve an ideal donor outcome, further work is necessary to minimize the negative effects as well as to incorporate recent progress in regenerative medicine.

    Donor safety and preservation of donor health after living liver donation are of paramount importance. Diarrhea has a significant influence on gastrointestinal quality of life among donors who have undergone living donor hepatectomy. Thus, we aimed to investigate predictors of diarrhea after hepatectomy and its impact on gastrointestinal quality of life in living donors. We retrospectively examined the medical records of 204 living liver donors who underwent hepatectomy during the period January 2010 to June 2013 at a single medical center. Diarrhea was defined as the passing of three or more liquid stools per day. The Chinese version of the Gastrointestinal Quality of Life Index (GIQLI) was used to assess the influence of diarrhea on quality of life in donors. During the study period, diarrhea was diagnosed in 62 (30.3%) of the 204 donors and the duration of diarrhea in the majority of them (n = 46, 74%) was factors associated with diarrhea included age [risk ratio (RR) = 0.84, 95% confidence interval (CI): 0.79-0.89, risk difference = 16%], and chronic cholecystitis (RR = 0.48, 95% CI: 0.24-0.99, risk difference = 52%). Compared to donors without diarrhea, donors with diarrhea had lower GIQLI scores in the following GIQLI domains: GI symptoms (1.8 vs. 3.6), physical function (2.1 vs. 3.5), emotional function (3.0 vs. 3.6), social function (3.3 vs. 3.7), and treatment reaction (2.6 vs. 3.7). Our findings show that younger donors and those without chronic cholecystitis are at increased risk for diarrhea after living donor hepatectomy and that diarrhea is associated with lower GIQLI scores after hepatectomy.

  1. Q-FISH measurement of hepatocyte telomere lengths in donor liver and graft after pediatric living-donor liver transplantation: donor age affects telomere length sustainability.

    Youichi Kawano

    Full Text Available Along with the increasing need for living-donor liver transplantation (LDLT, the issue of organ shortage has become a serious problem. Therefore, the use of organs from elderly donors has been increasing. While the short-term results of LDLT have greatly improved, problems affecting the long-term outcome of transplant patients remain unsolved. Furthermore, since contradictory data have been reported with regard to the relationship between donor age and LT/LDLT outcome, the question of whether the use of elderly donors influences the long-term outcome of a graft after LT/LDLT remains unsettled. To address whether hepatocyte telomere length reflects the outcome of LDLT, we analyzed the telomere lengths of hepatocytes in informative biopsy samples from 12 paired donors and recipients (grafts of pediatric LDLT more than 5 years after adult-to-child LDLT because of primary biliary atresia, using quantitative fluorescence in situ hybridization (Q-FISH. The telomere lengths in the paired samples showed a robust relationship between the donor and grafted hepatocytes (r = 0.765, p = 0.0038, demonstrating the feasibility of our Q-FISH method for cell-specific evaluation. While 8 pairs showed no significant difference between the telomere lengths for the donor and the recipient, the other 4 pairs showed significantly shorter telomeres in the recipient than in the donor. Multiple regression analysis revealed that the donors in the latter group were older than those in the former (p = 0.001. Despite the small number of subjects, this pilot study indicates that donor age is a crucial factor affecting telomere length sustainability in hepatocytes after pediatric LDLT, and that the telomeres in grafted livers may be elongated somewhat longer when the grafts are immunologically well controlled.

    Inborn metabolic diseases of the liver can be life-threatening disorders that cause debilitating and permanent neurological damage. Symptoms may manifest as early as the neonatal period. Liver transplant replaces the enzymatically deficient liver, allowing for metabolism of toxic metabolites. LDLT for metabolic disorders is rarely performed in the United States as compared to countries such as Japan, where they report >2000 cases performed within the past two decades. Patient and graft survival is comparable to that of the United States, where most of the studies are based on deceased donors. No living donor complications were observed, suggesting that LDLT is as safe and effective as deceased donor transplants performed in the USA. Increased utilization of living donors in the USA will allow for early transplantation to prevent permanent neurological damage in those with severe disease. Pediatric transplant centers should consider utilizing living donors when feasible for children with metabolic disorders of the liver.

    Acute kidney injury (AKI) is a common complication after liver transplantation (LT). Few studies investigating the incidence and risk factors for AKI after living donor liver transplantation (LDLT) have been published. LDLT recipients have a lower risk for post-LT AKI than deceased donor liver transplantation (DDLT) recipients because of higher quality liver grafts. We retrospectively reviewed LDLTs and DDLTs performed at the University of Pittsburgh Medical Center between January 2006 and December 2011. AKI was defined as a 50% increase in serum creatinine (SCr) from baseline (preoperative) values within 48 hours. One hundred LDLT and 424 DDLT recipients were included in the propensity score matching logistic model on the basis of age, sex, Model for End-Stage Liver Disease score, Child-Pugh score, pretransplant SCr, and preexisting diabetes mellitus. Eighty-six pairs were created after 1-to-1 propensity matching. The binary outcome of AKI was analyzed using mixed effects logistic regression, incorporating the main exposure of interest (LDLT versus DDLT) with the aforementioned matching criteria and postreperfusion syndrome, number of units of packed red blood cells, and donor age as fixed effects. In the corresponding matched data set, the incidence of AKI at 72 hours was 23.3% in the LDLT group, significantly lower than the 44.2% in the DDLT group (P = 0.004). Multivariate mixed effects logistic regression showed that living donor liver allografts were significantly associated with reduced odds of AKI at 72 hours after LT (P = 0.047; odds ratio, 0.31; 95% confidence interval, 0.096-0.984). The matched patients had lower body weights, better preserved liver functions, and more stable intraoperative hemodynamic parameters. The donors were also younger for the matched patients than for the unmatched patients. In conclusion, receiving a graft from a living donor has a protective effect against early post-LT AKI.

    AIM: To investigate the safety of adult-to-adult living donor liver transplantation (A-A LDLT) in both donors and recipients.METHODS: From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein (MHV), and 3 cases using dual grafts (one case using two left lobe, 2 using one right lobe and one left lobe). The most common diagnoses were hepatitis B liver cirrosis, 30 (60%) cases; and hepatocellular carcinoma, 15 (30%) cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease (MELD) with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients .RESULTS: Forty-nine right lobes and 3 left lobes (2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor) were obtained from 52 living donors. The 49 right lobe grafts, without MHV, weighed 400 g-850 g (media 550 g), and the ratio of graft volume to recipient standard liver volume (GV/SLV) ranged from 31.74% to 71.68% (mean 45.35%). All donors' remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow-up of 2-52 mo (media 9 mo), among 50 adult recipients, complications occurred in 13 (26%) cases and 4 (8%) died postoperatively within 3 mo. Their 1-year actual survival rate was 92%.CONCLUSION: When preoperative CT volumetry shows volume of remnant liver is more than 35%, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation

    Some living kidney donors incur economic consequences as a result of donation; however, these costs are poorly quantified. We developed a framework to comprehensively assess economic consequences from the donor perspective including out-of-pocket cost, lost wages and home productivity loss. We prospectively enrolled 100 living kidney donors from seven Canadian centers between 2004 and 2008 and collected and valued economic consequences ($CAD 2008) at 3 months and 1 year after donation. Almost all (96%) donors experienced economic consequences, with 94% reporting travel costs and 47% reporting lost pay. The average and median costs of lost pay were $2144 (SD 4167) and $0 (25th-75th percentile 0, 2794), respectively. For other expenses (travel, accommodation, medication and medical), mean and median costs were $1780 (SD 2504) and $821 (25th-75th percentile 242, 2271), respectively. From the donor perspective, mean cost was $3268 (SD 4704); one-third of donors incurred cost >$3000, and 15% >$8000. The majority of donors (83%) reported inability to perform usual household activities for an average duration of 33 days; 8% reported out-of-pocket costs for assistance with these activities. The economic impact of living kidney donation for some individuals is large. We advocate for programs to reimburse living donors for their legitimate costs.

    Full Text Available Situs inversus is a rare congenital abnormality that affects approximately 0.005% of all live births. Traditionally, this condition is considered as a contraindication for liver donation, primarily due to the peculiarities of the vascular anatomy and the diffi culties in graft placement in the abdominal cavity. Review of the world literature testifi es to fi ve cases of use of the whole liver from deceased donor with situs inversus in adult recipients, and to just one case of inverted right lobe transplantation from living donor to 53-year-old man. Thus, transplantation of an inverted left liver lobe from a living related donor in pediatric patients was performed for the fi rst time. The article presents a successful experience of liver transplantation in child with tyrosinemia type 1 from AB0-incompatible living donor with situs inversus.

    Living donor liver transplantation (LDLT) is an alternative therapeutic option for patients with end-stage hepatitis C virus (HCV) cirrhosis because of the cadaveric organ shortage. HCV infection is now a leading indication for LDLT among adults worldwide, and there is a worse prognosis with HCV recurrence. The antivirus strategy after transplantation, however, is currently under debate.Recent updates on the clinical and therapeutic aspects of living donor liver transplantation for HCV are discussed in the present review.

    Full Text Available Abstract Background Living donor liver transplantation (LDLT is a valuable and legitimate treatment for patients with end-stage liver disease. Computed tomography (CT has proven to be an important tool in the process of donor evaluation. The purpose of this study was to evaluate the significance of CT in the donor selection process. Methods Between May 1999 and October 2010 170 candidate donors underwent biphasic CT. We retrospectively reviewed the results of the CT and liver volumetry, and assessed reasons for rejection. Results 89 candidates underwent partial liver resection (52.4%. Based on the results of liver CT and volumetry 22 candidates were excluded as donors (31% of the cases. Reasons included fatty liver (n = 9, vascular anatomical variants (n = 4, incidental finding of hemangioma and focal nodular hyperplasia (n = 1 and small (n = 5 or large for size (n = 5 graft volume. Conclusion CT based imaging of the liver in combination with dedicated software plays a key role in the process of evaluation of candidates for LDLT. It may account for up to 1/3 of the contraindications for LDLT.

    Rosen, Amanda; Ison, Michael G

    2016-11-14

    Living organ donor candidates are screened for medical and psychosocial contraindications to donation. One important goal of this process is to prevent donor-derived infectious diseases transmissions. These transmissions are exceptionally rare, but have the potential to cause significant morbidity and mortality. The Organ Procurement and Transplantation Network now requires each recovery hospital to develop a protocol for evaluating living donors for tuberculosis and other geographically-defined endemic pathogens, including Trypanosoma cruzi (the causative pathogen of Chagas' disease), Strongyloides stercoralis, and West Nile Virus (WNV), in addition to universal screening for blood-borne pathogens. Enhanced screening requirements were developed in response to the changing epidemiology and endemicity of these diseases, as well as recent case reports of donor-derived disease transmission. Living organ donor disease screening presents a number of unique challenges to clinicians and policy-makers, including deciding which donors to test, which testing modality to use, when to test, and appropriate interpretation of results. This review will analyze the epidemiology of T. cruzi, S. stercoralis, and WNV, the assays available for screening for these diseases, and the subsequent impact on the living organ donor process .

    2015-07-01

    Ethicists and guidelines have suggested that potential living kidney donors who withdraw from evaluation be offered an 'alibi.' We sought to determine what potential living kidney donors are told about their ability to opt out, alibi availability and postwithdrawal confidentiality. We reviewed 148 consent forms for living kidney donor evaluation from US transplant centres that performed >5 living kidney transplants in 2010-2011 (response rate 87%). We found that while 98% of centres used evaluation consent forms that indicated that the donor could withdraw, only 21% of these documents offered an alibi. Another 23% of centres' consent forms indicated that the transplant team would be willing to inform the intended recipient that an individual was not a potential donor. Relatively few consent documents explicitly addressed the confidentiality of the donor's health information (31%), candidacy status (18%), decision (24%) or reasons (23%) following withdrawal. To preserve potential donors' autonomy and relationships, we advocate that all transplant centres offer general alibis in their evaluation consent forms. We conclude by offering recommendations for evaluation consent discussions of opting out, alibis and postwithdrawal confidentiality. Published by the BMJ Publishing Group Limited.

    Live-donor kidney transplantation (LDKT) is the best treatment for eligible people with late-stage kidney disease. Despite this, living kidney donation rates have declined in the United States in recent years. A potential source of this decline is the financial impact on potential and actual living kidney donors (LKDs). Recent evidence indicates that the economic climate may be associated with the decline in LDKT and that there are nontrivial financial ramifications for some LKDs. In June 2014, the American Society of Transplantation's Live Donor Community of Practice convened a Consensus Conference on Best Practices in Live Kidney Donation. The conference included transplant professionals, patients, and other key stakeholders (with the financial support of 10 other organizations) and sought to identify best practices, knowledge gaps, and opportunities pertaining to living kidney donation. This workgroup was tasked with exploring systemic and financial barriers to living kidney donation. The workgroup reviewed literature that assessed the financial effect of living kidney donation, analyzed employment and insurance factors, discussed international models for addressing direct and indirect costs faced by LKDs, and summarized current available resources. The workgroup developed the following series of recommendations to reduce financial and systemic barriers and achieve financial neutrality for LKDs: (1) allocate resources for standardized reimbursement of LKDs' lost wages and incidental costs; (2) pass legislation to offer employment and insurability protections to LKDs; (3) create an LKD financial toolkit to provide standardized, vetted education to donors and providers about options to maximize donor coverage and minimize financial effect within the current climate; and (4) promote further research to identify systemic barriers to living donation and LDKT to ensure the creation of mitigation strategies.

    Living donor segmental pancreas transplants (LDSPTx) have been performed selectively to offer a preemptive transplant option for simultaneous pancreas-kidney recipients and to perform a single operation decreasing the cost of pancreas after kidney transplant. For solitary pancreas transplants, this option historically provided a better immunologic match. Although short-term donor outcomes have been documented, there are no long-term studies. We studied postdonation outcomes in 46 segmental pancreas living donors. Surgical complications, risk factors (RF) for development of diabetes mellitus (DM) and quality of life were studied. A risk stratification model (RSM) for DM was created using predonation and postdonation RFs. Recipient outcomes were analyzed. Between January 1, 1994 and May 1, 2013, 46 LDSPTx were performed. Intraoperatively, 5 (11%) donors received transfusion. Overall, 9 (20%) donors underwent splenectomy. Postoperative complications included: 6 (13%) peripancreatic fluid collections and 2 (4%) pancreatitis episodes. Postdonation, DM requiring oral hypoglycemics was diagnosed in 7 (15%) donors and insulin-dependent DM in 5 (11%) donors. RSM with three predonation RFs (oral glucose tolerance test, basal insulin, fasting plasma glucose) and 1 postdonation RF, greater than 15% increase in body mass index from preoperative (Δ body mass index >15), predicted 12 (100%) donors that developed postdonation DM. Quality of life was not significantly affected by donation. Mean graft survival was 9.5 (±4.4) years from donors without and 9.6 (±5.4) years from donors with postdonation DM. LDSPTx can be performed with good recipient outcomes. The donation is associated with donor morbidity including impaired glucose control. Donor morbidity can be minimized by using RSM and predonation counseling on life style modifications postdonation.

    Background and objectives Living donor guidelines—both national and international—either do not address or are vague about what information can be shared between prospective living donors and transplant candidates, as well as when to make such disclosures and who should make them. This study explored the attitudes of donors and recipients regarding how much information they believe should be shared. Design, setting, participants, & measurements Two Email invitations were sent by the National Kidney Foundation (national headquarters) to its Email listservs, inviting members to participate in an online survey to assess the attitudes of kidney transplant stakeholders regarding the disclosure of health and health risk behavior information. Results From approximately 4200 unique Email addresses, 392 (9.3%) respondents completed part or all of the survey. The analyses were limited to the 236 respondents who self-identified as either donors (potential and actual, n=160) or recipients (candidates and actual, n=76). Overall, 79% (186 of 234) of respondents supported disclosure of general recipient health information that would affect post-transplant outcome to donors, and 88% (207 of 235) supported disclosure of general donor health information to recipients. Recipients and donors were also supportive of sharing donor and recipient information, particularly information relevant to graft and patient survival. There is some reticence, however, about sharing social information. The closer the relationship, the more information they are willing to share. Both donors and recipients wanted the transplant team involved in the information disclosure. Over three quarters of donors (79%) and recipients (78%) did not think the recipient had a right to know why a donor was excluded from donating. Conclusions Both donors and recipients want a significant amount of health information to be disclosed. The opinions of other stakeholders need to be surveyed to determine whether a

    The selection of living kidney donors is based on a formal evaluation of the state of health. However, this spectrum of health includes subtle metabolic derangements that can cluster as metabolic syndrome. We studied the association of metabolic syndrome with kidney function and histology in 410 donors from 2005 to 2012, of whom 178 donors were systematically followed after donation since 2009. Metabolic syndrome was defined as per the NCEP ATPIII criteria, but using a BMI > 25 kg/m(2) instead of waist circumference. Following donation, donors received counseling on lifestyle modification. Metabolic syndrome was present in 50 (12.2%) donors. Donors with metabolic syndrome were more likely to have chronic histological changes on implant biopsies than donors with no metabolic syndrome (29.0% vs. 9.3%, p kidney function recovery following donation. At last follow-up, reversal of metabolic syndrome was observed in 57.1% of donors with predonation metabolic syndrome, while only 10.8% of donors developed de novo metabolic syndrome (p histological changes, and nephrectomy in these donors was associated with subsequent protracted recovery of kidney function. Importantly, weight loss led to improvement of most abnormalities that define metabolic syndrome.

    The independent living donor advocate (ILDA) serves a mandated and supportive role in the care of the living organ donor, yet qualifications and role requirements are not clearly defined. Guidance comes from Centers for Medicare and Medicaid Services (CMS) Conditions for Transplant Center Participation and interpretive guidelines, Organ Procurement and Transplantation Network (OPTN) Policy and CMS and OPTN site surveys, yet interpretation of regulations varies. Herein, the AST Living Donor Community of Practice (LDCOP) offers seven recommendations to clarify and optimize the ILDA role: (a) the ILDA must have a certain skill set rather than a specific profession, (b) the ILDA must be educated and demonstrate competence in core knowledge components, (c) the ILDA's primary role is to assess components of informed consent, (d) centers must develop a transparent system to define ILDA independence, (e) the ILDA should have a reporting structure outside the transplant center, (f) the ILDA's role should be integrated throughout the donor care continuum, (g) the ILDA role should include a narrow "veto power." We address controversies in ILDA implementation, and offer pathways to maximize benefits and minimize limitations of approaches that may each meet regulatory requirements but confer different practice benefits. We propose a research agenda to explore the impact of the ILDA. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    To study the allele frequencies and their polymorphism characteristics of human platelet antigen (HPA) and human leucocyte antigen-I (HLA-I) in Chinese xi'an population, the types of HPA and HLA-I in 375 Chinese xi'an voluntary platelet donors were detected by PCR-SSP and PCR-SSO as well as flow cytometry with magnetic beads, and were analyzed. The results showed that there was no polymorphism in HPA-7-HPA-14, HPA-16 and HPA-17 which only expressed-aa type, the -bb type was only detected in HPA-3 and HPA-15, 9 out of 16 samples for the HPA-5ab phenotype simultaneously expressed HPA-15ab, the other 7 samples expressed HPA-15bb, no HPA-15aa phenotype was observed. Phenotypes detected in this study were HPA-1aa-17aa, HPA-1ab, -2ab, -3ab, -3bb, -4ab, -5ab, -6ab, -15ab and -15bb. Among 375 cases, HLA-A specificity of 16 species was observed, which accounted for 76% (16/21) of detectable phenotype specificity in this locus, moreover, 11 species showed frequency > 1%; HLA-B specificity of 36 species was observed which accounted for 84% (36/43) of detectable phenotype specificity in this locus, moreover 23 species showed frequency > 1%, these species were covered by common specific HLA-I in northern China, 264 species haplotype HLA-A-B were found in 375 cases, the frequency of 30 species was > 1%. It is concluded that the gene frequency distribution of HPA and HLA-I in Chinese Xi'an population is in accordance with population of northern China on the whole, but it has its own characteristics.

    In living donor liver transplantation (LDLT), insufficient graft volume could result in small-for-size syndrome in recipients, whereas major liver donation predisposes the donor to a high risk of posthepatectomy liver failure. Dual graft LDLT is therefore introduced to obtain combined graft sufficiency. To date, 367 patients have been reported worldwide. We reviewed all the relevant literature, with a special focus on 43 case reports containing enough data to extract and analyze. A simple decision-making algorithm was developed. Dual graft LDLT is indicated when (1) a single donation is unacceptable due to graft-to-recipient size mismatch; (2) the future liver remnant is insufficient in the single donor after major resection; or (3) there is a significant underlying disorder or anatomical variation within the donor liver. The outcome of dual graft LDLT is reported to be comparable with that of single donor LDLT. Unilateral graft atrophy was found in 7 of the 43 patients, predominantly in the right-sided, heterotopic and initially smaller grafts. Technically, the heterotopic implantation and complex vascular reconstruction are the most demanding. Elaborate surgical planning and modification are needed. Ethical concerns about involving a second living donor need to be addressed. In conclusion, dual graft LDLT should be prudently performed in select cases by surgeons of proven expertise when single donation is unacceptable and a second living donor is available. The decision-making criteria need to be standardized. More surgical modification and clinical research are needed.

  7. The impact of living-unrelated transplant on establishing deceased-donor liver program in Syria.

    Liver transplant is the criterion standard for patients with end-stage liver disease. Yet there is no liver transplant in Syria. Traveling abroad for a liver transplant is a luxury few Syrians can afford. There is currently an on-going debate whether to start a liver transplant program using living or deceased donors. In 2003, a new law was enacted, authorizing the use of organs from volunteer strangers and deceased donors. Despite the positive aspects of this law (allowing unrelated donors to increase the number of transplants in the country); the negative aspects also were obvious. The poor used the law to sell their organs to the rich, and this model is in violation of the Istanbul Declaration. To better document transplant communities' perceptions on organ donation, an e-mail survey was sent to a nationally representative sample of physicians (n = 115) that showed that 58% of respondents did not support the start of liver transplant from live donors, as they fear a considerable risk for the donor and the recipient. Seventy-one percent of respondents believe that unrelated kidney donation has contributed to tarnishing the reputation of transplant, and 56% believe that a deceased-donor program can run in parallel with unrelated organ donations. The interest in deceased-donor program has been affected negatively by the systematic approach of using poor persons as the source of the organ. This lack of interest has affected starting a liver program that relies on deceased donors; especially the need for kidneys is more than livers. Health authorities in Syria were inclined to initiate a liver transplant program from live donors, despite the risks of serious morbidities and mortality. In conclusion then, paid kidney donation in actual effect is actually a hindrance to establishing a deceased-donor liver program.

    2013-01-01

    Summary Background and objectives For eligible candidates, transplantation is considered the optimal treatment compared with dialysis for patients with ESRD. The growing number of patients with ESRD requires new strategies to increase the pool of potential donors. Design, setting, participants, & measurements Using decision analysis modeling, this study compared a strategy of paying living kidney donors to waitlisted recipients on dialysis with the current organ donation system. In the base case estimate, this study assumed that the number of donors would increase by 5% with a payment of $10,000. Quality of life estimates, resource use, and costs (2010 Canadian dollars) were based on the best available published data. Results Compared with the current organ donation system, a strategy of increasing the number of kidneys for transplantation by 5% by paying living donors $10,000 has an incremental cost-savings of $340 and a gain of 0.11 quality-adjusted life years. Increasing the number of kidneys for transplantation by 10% and 20% would translate into incremental cost-savings of $1640 and $4030 and incremental quality-adjusted life years gain of 0.21 and 0.39, respectively. Conclusion Although the impact is uncertain, this model suggests that a strategy of paying living donors to increase the number of kidneys available for transplantation could be cost-effective, even with a transplant rate increase of only 5%. Future work needs to examine the feasibility, legal policy, ethics, and public perception of a strategy to pay living donors. PMID:24158797

    Full Text Available New onset diabetes after transplantation (NODAT occurs less frequently in living donor liver transplant (LDLT recipients than in deceased donor liver transplant (DDLT recipients. The aim of this study was to compare the incidence and predictive factors for NODAT in LDLT versus DDLT recipients. The Organ Procurement and Transplant Network/United Network for Organ Sharing database was reviewed from 2004 to 2010, and 902 LDLT and 19,582 DDLT nondiabetic recipients were included. The overall incidence of NODAT was 12.2% at 1 year after liver transplantation. At 1, 3, and 5 years after transplant, the incidence of NODAT in LDLT recipients was 7.4, 2.1, and 2.6%, respectively, compared to 12.5, 3.4, and 1.9%, respectively, in DDLT recipients. LDLT recipients have a lower risk of NODAT compared to DDLT recipients (hazard ratio = 0.63 (0.52–0.75, P<0.001. Predictors for NODAT in LDLT recipients were hepatitis C (HCV and treated acute cellular rejection (ACR. Risk factors in DDLT recipients were recipient male gender, recipient age, body mass index, donor age, donor diabetes, HCV, and treated ACR. LDLT recipients have a lower incidence and fewer risk factors for NODAT compared to DDLT recipients. Early identification of risk factors will assist timely clinical interventions to prevent NODAT complications.

    2010-04-01

    Full Text Available Abstract Introduction Obese living donors who undergo donor nephrectomy have higher rates of intra-operative and post-operative complications. Many centres exclude obese donors from living donor transplant programs. Diet, exercise and medication are often ineffective weight loss interventions for donors, hence bariatric surgery should be considered. Case presentation We report the case of a 53-year-old Caucasian woman who underwent laparoscopically adjustable gastric banding. The procedure enabled her to lose sufficient weight to gain eligibility for kidney donation. After losing weight, she had an uncomplicated laparoscopic donor nephrectomy surgery, and the recipient underwent successful kidney transplantation. Conclusion Laparoscopically adjustable gastric banding should be considered for obese potential living kidney donors whenever transplantation units restrict access to donor nephrectomy based on the increased surgical risk for donors.

    Abstract Rationale: With the development of laparoscopic technique, the total laparoscopic living donor right hemihepatectomy (LLDRH) procurement surgery has been successfully performed in many liver transplant centers all over the world, and the number of cases is continuing to increase. We report our case of laparoscopic right graft resection with venous outflow reconstruction using cadaveric common iliac artery allograft in our center and review literatures about total LLDRH surgery. Patient concerns and Diagnoses: A 40-year-old male living donor for right hepatectomy was selected after pretransplant evaluation including laboratory tests, liver volume, anatomy of hepatic vein, artery, portal vein, and bile duct. Living donor liver transplantation surgery was approved by Sichuan Provincial Health Department and the ethics committee of the West China Hospital, Sichuan University. Interventions: Hepatic parenchyma transection was performed by ultrasonic scalpel and Cavitron Ultrasonic Surgical Aspirator (CUSA). Right branch of portal vein, right hepatic artery, right hepatic duct, and right hepatic vein were meticulously dissected. The right hepatic duct was ligated and transected 2 mm far from the bifurcation of common hepatic duct, right hepatic artery, and portal vein were also ligated and transected, the right hepatic vein was transected by laparoscopic linear cutting stapler. The gap between short hepatic veins and right hepatic vein was bridged and reconstructed by cadaveric common iliac artery allograft. Outcomes: The operation time was 480 minutes and warm ischemia time was 4 minutes. Blood loss was 300 mL without blood transfusion. The donor was discharged on postoperative day 7 uneventfully without complications. Literatures about laparoscopic living donor right hemihepatectomy are compared and summarized in table. Lessons: The total laparoscopic living donor right hemihepatectomy is technically feasible and safe in some transplant centers which

    2011-01-01

    Full Text Available With the notable growth in the qualitative investigation of living kidney donation, there is value in aggregating results from this body of research to learn from accumulated experience. The present paper aims to draw a complete portrait of living donors' and recipients' experience of donation by metasummarizing published studies. We found that donors' experience, particularly the decision-making process, has been more extensively studied than the recipients' perspective. Donors differ in their initial level of motivation to donate but on the whole report positive experiences and personal benefits. They also identify difficult periods and the need for additional resources. Recipients report an often positive but more ambivalent reaction to donation. In terms of relational issues between dyads, while the topic remains understudied, the donor-recipient relationship and gift reciprocity have received the most attention. Results are discussed in terms of their implications for future practice and research.

    There is enough evidence concerning the short-term safety of living donors after kidney transplantation. However, long-term complications continue to be studied, with a particular interest in young donors. Previous studies have been conducted in older donors for adult renal patients. We present a study of long-term complications in kidney donors for our paediatric population. We carried out a long-term donor study for the 54 living kidney-donor transplantations performed at our department from 1979 to June 2014. We monitored the glomerular filtration rate (GFR) on the basis of 24-hour urine creatinine clearance, 24-hour proteinuria and the development of arterial hypertension in the 48 donors who were followed up for more than one year. Only the 39 patients who were exclusively followed up by our department have been included in the results analysis. GFR through creatinine clearance was stable after an initial decrease. No proteinuria was observed in any of the cases. One patient developed chronic kidney disease (CKD), which resulted in a cumulative incidence of 2%. GFR below 60mL/min/1.73 m(2) was not reported in any other patients. Arterial hypertension was diagnosed in 25% of donors, 90% of which were treated with antihypertensives. Risk of CKD and hypertension in living kidney donors for paediatric recipients, who are carefully monitored throughout their evolution, is similar to that of the general population. Therefore, this technique appears to be safe in both the short and long term. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

    First experience of application of the blood autodonorship programme, using recombinant erythropoietin (Eprex) plus preparations containing iron during their preparation for partial hepatic resection, was analyzed. Realization of this programme had permitted to escape the performance of allogenic hemotransfusion in 71.4% of donors, in whom the right or left hepatic lobe was taken out and in 100%--the left lateral section. The erythropoietin dosage regimes in different types of hepatic resections in living kindred donors were proposed.

    Socioeconomically deprived individuals with renal disease are less likely to receive a live-donor kidney transplant than less-deprived individuals. This qualitative study aimed to identify reasons for the observed socioeconomic disparity in live-donor kidney transplantation. A qualitative study using face-to-face in-depth semistructured interviews. A UK tertiary renal referral hospital and transplant centre. Purposive sampling was used to select deceased-donor transplant recipients from areas of high socioeconomic deprivation (SED) (19 participants), followed by a low SED comparison group (13 participants), aiming for maximum diversity in terms of age, gender, ethnicity, primary renal disease and previous renal replacement therapy. Participants were interviewed following their routine transplant clinic review. Interviews were digitally audio-recorded and transcribed verbatim. Transcripts were coded using NVivo software and analysed using the constant comparison method described in Grounded Theory. Themes common and distinct to each socioeconomic group emerged. 6 themes appeared to distinguish between individuals from areas of high and low SED. 4 themes were distinct to participants from areas of high SED: (1) Passivity, (2) Disempowerment, (3) Lack of social support and (4) Short-term focus. 2 themes were distinct to the low SED group: (1) Financial concerns and (2) Location of donor. Several of the emerging themes from the high SED individuals relate to an individual's lack of confidence and skill in managing their health and healthcare; themes that are in keeping with low levels of patient activation. Inadequate empowerment of socioeconomically deprived individuals by healthcare practitioners was also described. Financial concerns did not emerge as a barrier from interviews with the high SED group. Interventions aiming to redress the observed socioeconomic inequity should be targeted at both patients and clinical teams to increase empowerment and ensure shared

    @@ Lung transplantation has been performed internationally as an effective treatment for a variety of end-stage lung diseases. A great disparity between the supply of donor organs and the demand of potential recipients has resulted in longer waiting time and annual increases in deaths on the lung transplant waiting list. Living-donor lobar lung transplantation (LDLLT) has become an established strategy to deal with the shortage of cadaveric donors. Encouraged by Starnes et al1 and Date et al,2 we began to apply the operation to a critically ill patient with bronchopulmonary dysplasia (BPD) firstly at Shanghai Pulmonary Hospital in China.

    Most centers utilize phone or written surveys to screen candidates who self-refer to be living kidney donors. To increase efficiency and reduce resource utilization, we developed a web-based application to screen kidney donor candidates. The aim of this study was to evaluate the use of this web-based application. Method and time of referral were tabulated and descriptive statistics summarized demographic characteristics. Time series analyses evaluated use over time. Between January 1, 2011 and March 31, 2012, 1200 candidates self-referred to be living kidney donors at our center. Eight hundred one candidates (67%) completed the web-based survey and 399 (33%) completed a phone survey. Thirty-nine percent of donors accessed the application on nights and weekends. Postimplementation of the web-based application, there was a statistically significant increase (p web-based application as opposed to telephone contact. Also, there was a significant increase (p = 0.025) in the total number of self-referrals post-implementation from 61 to 116 per month. An interactive web-based application is an effective strategy for the initial screening of donor candidates. The web-based application increased the ability to interface with donors, process them efficiently and ultimately increased donor self-referral at our center. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Despite its superior outcomes relative to chronic dialysis and deceased donor kidney transplantation, live donor kidney transplantation (LDKT) is less likely to occur in minorities, older adults, and poor patients than in those who are white, younger, and have higher household income. In addition, there is considerable geographic variability in LDKT rates. Concomitantly, in recent years, the rate of living kidney donation (LKD) has stopped increasing and is declining, after decades of consistent growth. Particularly noteworthy is the decline in LKD among black, younger, male, and lower-income adults. The Live Donor Community of Practice within the American Society of Transplantation, with financial support from 10 other organizations, held a Consensus Conference on Best Practices in Live Kidney Donation in June 2014. The purpose of this meeting was to identify LKD best practices and knowledge gaps that might influence LDKT, with a focus on patient and donor education, evaluation efficiencies, disparities, and systemic barriers to LKD. In this article, we discuss trends in LDKT/LKD and emerging novel strategies for attenuating disparities, and we offer specific recommendations for future clinical practice, education, research, and policy from the Consensus Conference Workgroup focused on disparities.

    We analyzed the clinical manifestations and experiences of diagnosing and treating central pontine myelinolysis following living donor liver transplantation. The clinical data of three patients with central pontine myelinolysis following living donor liver transplantation from January 2005 to November 2007 were retrospectively analyzed at the West China Hospital, Sichuan University, China.The three patients developed hyponatremia prior to surgery. Case 1 suffered locked-in syndrome following surgery, and received a large dose of gamma globulin,and subsequently recovered. Case 2 was in a coma for three days, and received hyperbaric chamber treatment.This patient remained in a mild coma for six months following surgery. Case 3 developed consciousness disturbances, gradually went into a coma following surgery, and died due to pulmonary infection. Central pontine myelinolysis is a severe complication in patients following living donor liver transplantation. Largedose gamma globulin treatment, as well as hyperbaric oxygen, might be effective therapeutic methods.

    Previously reported short-term results after live kidney donation show no negative consequences for the donor. The incidence of new-onset morbidity takes years to emerge, making it highly likely that this will be missed during short-term follow-up. Therefore, evidence on long-term outcome is essential. A 10-year follow-up on renal function, hypertension, quality of life (QOL), fatigue, and survival was performed of a prospective cohort of 100 donors. After a median follow-up time of 10 years, clinical data were available for 97 donors and QOL data for 74 donors. Nine donors died during follow-up of unrelated causes to donation, and one donor was lost to follow-up. There was a significant decrease in kidney function of 12.9 ml/min (P QOL showed significant clinically relevant decreases of 10-year follow-up scores in SF-36 dimensions of physical function (P motivation (P = 0.030). New-onset hypertension was present in 25.6% of the donors. Donor outcomes are excellent 10 years post-donation. Kidney function appears stable, and hypertension does not seem to occur more frequently compared to the general population.

    BACKGROUND: The right lobe of the liver is generally preferred for living donor liver transplantation in adult patients with end-stage liver disease. It is important to know the preoperative factors relating to the major postoperative complications. We therefore evaluated the possible risk factors for predicting post-operative complications in right lobe liver donors. METHODS: Data from 378 donors who had undergone right lobe hepatectomy at our center were evaluated retrospectively. The factors we evaluated included donor age, gender, body mass index (BMI), remnant liver volume, operation time, history of previous abdominal surgery, inclusion of the middle hepatic vein and variations in the portal and bile systems. RESULTS: Of the 378 donors, 219 were male and 159 female. None of the donors died, but 124 (32.8%) donors experienced complications including major complications (Clavien scores III and IV) in 27 (7.1%). Univariate analysis showed that complica-tions were signiifcantly associated with male gender and higher BMI (P0.05). Multivariate logistic regression analysis showed that major complications were signiifcantly associated with male gender (P=0.005) and higher BMI (P=0.029). Moreover, the Chi-square test showed that there were signiifcant relationships be-tween major complications and male gender (P=0.010, χ2=6.614, df=1) and BMI >25 kg/m2 (P=0.031, χ2=8.562, df=1). Of the 96 male donors with BMI >25 kg/m2, 14 (14.6%) with major com-plications had signiifcantly smaller mean remnant liver volume than those (82, 85.4%)

    Objective To document the safety and efficacy of laparoscopic living donor hepatectomy in comparison with open liver resection for living donor liver transplantation. Methods Medline database, EMASE and Cochrane library were searched for original studies comparing laparoscopic living donor hepatectomy (LLDH) and open living donor hepatectomy (OLDH) by January 2015. Meta-analysis was performed to evaluate donors’ perioperative outcomes. Results Nine studies met selection criteria, involving 1346 donors of whom 318 underwent LLDH and 1028 underwent OLDH. The Meta analysis demonstrated that LLDH group had less operative blood loss [patients 1346; WMD: -56.09 mL; 95%CI: -100.28-(-11.90) mL; P = 0.01], shorter hospital stay [patients 737; WMD: -1.75 d; 95%CI: -3.01-(-0.48) d; P = 0.007] but longer operative time (patients 1346; WMD: 41.05 min; 95%CI: 1.91–80.19 min; P = 0.04), compared with OLDH group. There were no significant difference in other outcomes between LLDH and OLDH groups, including overall complication, bile leakage, postoperative bleeding, pulmonary complication, wound complication, time to dietary intake and period of analgesic use. Conclusions LLDH appears to be a safe and effective option for LDLT. It improves donors’ perioperative outcomes as compared with OLDH. PMID:27788201

    Living kidney donor evaluation commonly includes nuclear renography to assess split kidney function and computed tomography (CT) scan to evaluate anatomy. To streamline donor workup and minimize exposure to radioisotopes, we sought to assess the feasibility of using proportional kidney volume from CT volumetry in lieu of nuclear renography. We examined the correlation between techniques and assessed their ability to predict residual postoperative kidney function following live donor nephrectomy. In a cohort of 224 live kidney donors, we compared proportional kidney volume derived by CT volumetry with split kidney function derived from nuclear renography and found only modest correlation (left kidney R(2) =26.2%, right kidney R(2) =26.7%). In a subset of 88 live kidney donors with serum creatinine measured 6 months postoperatively, we compared observed estimated glomerular filtration rate (eGFR) at 6 months with predicted eGFR from preoperative imaging. Compared to nuclear renography, CT volumetry more closely approximated actual observed postoperative eGFR for Chronic Kidney Disease Epidemiology Collaboration (J-test: P=.02, Cox-Pesaran test: P=.01) and Mayo formulas (J-test: P=.004, Cox-Pesaran test: Pvolumetry for estimation of split kidney function in healthy individuals with normal kidney function and morphology.

  10. Right Gastroepiploic Artery as an Alternative for Arterial Reconstruction in Living Donor Liver Transplantation

    2014-01-01

    Full Text Available Background. An adequate blood flow is directly related to graft survival in living donor liver transplantation. However, in some cases, unfavorable conditions prevent the use of the hepatic artery for arterial reconstruction. Herein, we report a case in which the recipient right gastroepiploic artery was used as an option for arterial reconstruction in adult-to-adult living donor liver transplantation. Case Report. A 62-year-old woman, with cirrhosis due to hepatitis B associated with hepatocellular carcinoma, was submitted to living donor liver transplantation. During surgery, thrombosis of the hepatic artery with intimal dissection until the celiac trunk was observed, which precluded its use in arterial reconstruction. We decided to use the right gastroepiploic artery for arterial revascularization of the liver graft. Despite the discrepancy in size between donor hepatic artery and recipient right gastroepiploic artery, anastomosis was performed successfully. Conclusions. The use of the right gastroepiploic artery as an alternative for arterial revascularization of the liver graft in living donor liver transplantation should always be considered when the hepatic artery of the recipient cannot be used. For performing this type of procedure, familiarity with microsurgical techniques by the surgical team is necessary.

    Objective Live kidney donation is generally viewed as a welcome treatment option for severe kidney disease. However, there is a disparity in the body of research on donor experiences and postdonation outcome, and lack of knowledge on long-term consequences described by the donors. This study was conducted to provide insight into donors' subjective meanings and interpretation of their experiences ∼10 years after donation. Design Qualitative explorative in-depth interviews. The sampling strategy employed maximum variation. Setting Oslo University Hospital is the national centre for organ transplantation and donation in Norway, and there are 26 local nephrology centres. Participants 16 donors representing all parts of Norway who donated a kidney in 2001–2004 participated in the study. The interviews were analysed using an interpretative approach. Results The analysis resulted in 4 main themes; the recipient outcome justified long-term experiences, family dynamics—tension still under the surface, ambivalence—healthy versus the need for regular follow-up, and life must go on. These themes reflect the complexity of live kidney donation, which fluctuated from positive experiences such as pride and feeling privileged to adverse experiences such as altered family relationships or reduced health. Conclusions Live kidney donors seemed to possess resilient qualities that enabled them to address the long-term consequences of donation. The challenge is to provide more uniform information about long-term consequences. In future research, resilient qualities could be a topic to explore in live donation. PMID:28209606

    The kidney transplantation, as a method of medical treatment, could not be developed faster in our country for many years. A number of demands for transplantation grows much faster than our modest capability. The similar, but in a rather smaller degree, this problem occurs in some other countries in the world. The main cause is: the organization of corpse collecting and the conservatism of doctors. The latter problem, in the countries of western hemisphere, is surpassed more easily by a doctor codex and a legal obligation that involves doctors actively in this process, which is not the case in our country. The organization of corpse collecting in some states of the USA is highly developed, but however it does not give sufficient number of organs for the cadaveric transplantation. New, additional possibilities are found: the taking of even organs (kidneys) from alive unrelated donors, spouses, which excludes the possibility of greed and gives, only in the USA, about 1.500 additional alive transplantations per year. The complementary medical attitude towards the increasing of number of cadaveric transplantations is: considerably freely taking of kidneys from cadavers without tissue compatibility, only with the compatibility of blood groups of ABO system. Since the immunological criteria, in our country, are very intensified by the Zagreb immunology group, e.g. from 75-100% for alive transplantation, or the minimum of 50% tissue compatibility for cadaveric transplantation, this old-fashioned attitude has considerably lowered the number of transplantations in our country.(ABSTRACT TRUNCATED AT 250 WORDS)

Methods From 2006, January to 2012, December, replacement and voluntary donors were recruited by hospital and center blood station respectively, and all the donors were screened HBsAg, anti-HCV, anti-HIV (1 + 2), syphilis and ALT in center blood station twice. Results In 217 323 volunteers and 1 834 replacement donors, the total seroprevalence was higher in replacement group than in voluntary group (8.67% vs 6.31%), but the prevalence of ALT were not significantly differences. The prevalence of HBsAg, anti-HCV and syphilis were higher in replacement group than in voluntary group. Conclusions Generally, volunteers cloud provide more viral safety than replacement donors, who should be the main source of blood supply. But with appropriate intervention measures, such as pre-donor screening and other donor selection policy, replacement donors and voluntary donors provide a similar level of viral safety.

    A 35-year-old mother was scheduled to be the living donor for liver transplantation to her second son, who suffered from biliary atresia complicated with biliary cirrhosis at the age of 2 years. The operative plan was to recover the left lateral segment of the mother's liver for living donor transplantation. With the use of cholangiography at the time of surgery, we found the right anterior segmental duct (RASD) emptying directly into the cystic duct, and the catheter passed into the RASD. After repairing the incision in the cystic duct, transplantation was successfully performed. Her postoperative course was uneventful. Biliary anatomical variations were frequently encountered, however, this variation has very rarely been reported. If the RASD was divided, the repair would be very difficult because the duct will not dilate sufficiently in an otherwise healthy donor. Meticulous preoperative evaluation of the living donor's biliary anatomy, especially using magnetic resonance cholangiography and careful intraoperative techniques, is important to prevent bile duct injury and avoid the risk to the healthy donor.

    The decrease in the number of cadaveric donors has proved a limiting factor in the number of liver transplants, leading to the death of many patients on the waiting list. The living donor liver transplantation is an option that allows, in selected cases, increase the number of donors. One of the most serious complications in liver transplantation is hepatic artery thrombosis, in the past considered potentially fatal without urgent re-transplantation. A white male patient, 48 years old, diagnosed with hepatocellular carcinoma in chronic liver failure caused by hepatitis B virus, underwent living donor liver transplantation (right lobe). Doppler echocardiography performed in the immediate postoperative period did not identify arterial flow in the right branch, having been confirmed thrombosis of the right hepatic artery in CT angiography. Urgent re-laparotomy was performed, which consisted of thrombectomy and re-anastomosis of the hepatic artery with segmental splenic artery allograft interposition. The patient started anticoagulation and antiplatelet therapy with acetylsalicylic acid. Serial evaluation with Doppler echocardiography showed hepatic artery patency. At present, the patient is asymptomatic. One of the most devastating complications in liver transplantation, and particularly in living liver donor, is thrombosis of the hepatic artery; thus, early diagnosis and treatment is vital. The rapid intervention for revascularization of the graft avoids irreversible ischemia of the bile ducts and hepatic parenchyma, thus avoiding the need for re-transplantation.

    A shortage of organs for transplantation has forced surgeons to optimize the use of marginal organs, such as kidneys with arterial disease. We present a retrospective study of the outcome of donors with renal artery disease and recipients of kidneys from living related and unrelated donors. Kidneys with vascular abnormalities from healthy living donors were grafted into 11 recipients. These kidney transplants comprised 1.8% of those performed at our institution. The vascular abnormalities were aneurysms in 3 cases, atherosclerotic lesions in 4 and fibromuscular dysplasia in 4. After nephrectomy all abnormalities were corrected under hypothermic conditions during bench surgery except in 3 cases of ostial atherosclerotic plaque, which was left in the donors. The renal artery was anastomosed to the external iliac artery in 5 cases and to the internal iliac artery in 6. The ureter was reimplanted using an extravesical technique. All patients had immediate diuresis and no delayed post-transplant graft dysfunction was observed. One patient died of an unrelated cause and 3 had post-transplant graft function loss due to acute vasculopathy in 1, post-diarrhea with acute arterial thrombosis in 1 and recurrence of the hemolytic-uremic syndrome in 1. All remaining patients are well with median serum creatinine of 1.4 mg./dl. (normal 0.4 to 1.4). All donors are well and normotensive with normal renal function. The use of kidneys with arterial disease from living donors with unilateral disease is safe. Complete informed consent regarding the risks and benefits by donor and recipient is mandatory.

    The growing demand for liver transplantation and the concomitant scarcity of cadaveric livers have increased the need for living donor liver transplantation (LDLT). Ensuring the safety of donors and recipients is critical. The preoperative identification of the vascular and biliary tract anatomy with 3-dimensional (3D) printing may allow better preoperative surgical planning, avert unnecessary surgery in patients with potentially unsuitable anatomy, and thereby decrease the complications of liver transplant surgery. We developed a protocol and successfully 3D-printed synthetic livers (along with their complex networks of vascular and biliary structures) replicating the native livers of 6 patients: 3 living donors and 3 respective recipients who underwent LDLT. To our knowledge, these are the first complete 3D-printed livers. Using standardized preoperative, intraoperative, and postoperative assessments, we demonstrated identical anatomical and geometrical landmarks in the 3D-printed models and native livers.

    By the end of the first year, serum hemoglobin, calcium, albumin, HDL, bilirubin, AST, ALT were increased statistically. But serum phosphate, globulin were decreased statistically. In conclusion, successful ABO incompatible living donor kidney transplantation would restore a normal nutritional status even though the patients were performed plasmapheresis during the pre-transplant period.

    Full Text Available CONTEXT: Living donor liver transplantation has become an alternative to reduce the lack of organ donation. OBJECTIVE: To identify factors predictive of early graft loss in the first 3 months after living donor liver transplantation. METHODS: Seventy-eight adults submitted to living donor liver transplantation were divided into group I with 62 (79.5% patients with graft survival longer than 3 months, and group II with 16 (20.5% patients who died and/or showed graft failure within 3 months after liver transplantation. The variables analyzed were gender, age, etiology of liver disease, Child-Pugh classification, model of end-stage liver disease (MELD score, pretransplantation serum sodium level, and graft weight-to-recipient body weight (GRBW ratio. The GRBW ratio was categorized into 18. The chi-square test, Student t-test and uni- and multivariate analysis were used for the evaluation of risk factors for early graft loss. RESULTS: MELD score 135 mEq/L (P = 0.03 were higher in group II than in group I. In the multivariate analysis MELD scores > 18 (P18 and GRBW < 0.8 ratios are associated with higher probability of graft failure after living donor liver transplantation.

    Previously reported short-term results after live kidney donation show no negative consequences for the donor. The incidence of new-onset morbidity takes years to emerge, making it highly likely that this will be missed during short-term follow-up. Therefore, evidence on long-term outcome is essenti

    Abstract The 2017 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline on the Evaluation and Care of Living Kidney Donors is intended to assist medical professionals who evaluate living kidney donor candidates and provide care before, during and after donation. The guideline development process followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach and guideline recommendations are based on systematic reviews of relevant studies that included critical appraisal of the quality of the evidence and the strength of recommendations. However, many recommendations, for which there was no evidence or no systematic search for evidence was undertaken by the Evidence Review Team, were issued as ungraded expert opinion recommendations. The guideline work group concluded that a comprehensive approach to risk assessment should replace decisions based on assessments of single risk factors in isolation. Original data analyses were undertaken to produce a “proof-in-concept” risk-prediction model for kidney failure to support a framework for quantitative risk assessment in the donor candidate evaluation and defensible shared decision making. This framework is grounded in the simultaneous consideration of each candidate's profile of demographic and health characteristics. The processes and framework for the donor candidate evaluation are presented, along with recommendations for optimal care before, during, and after donation. Limitations of the evidence are discussed, especially regarding the lack of definitive prospective studies and clinical outcome trials. Suggestions for future research, including the need for continued refinement of long-term risk prediction and novel approaches to estimating donation-attributable risks, are also provided.

    Full Text Available Abstract Background Limited data exist on the impact of living kidney donation on the donor-recipient relationship. Purpose of this study was to explore motivations to donate or accept a (living donor kidney, whether expected relationship changes influence decision making and whether relationship changes are actually experienced. Methods We conducted 6 focus groups in 47 of 114 invited individuals (41%, asking retrospectively about motivations and decision making around transplantation. We used qualitative and quantitative methods to analyze the focus group transcripts. Results Most deceased donor kidney recipients had a potential living donor available which they refused or did not want. They mostly waited for a deceased donor because of concern for the donor’s health (75%. They more often expected negative relationship changes than living donor kidney recipients (75% vs. 27%, p = 0.01 who also expected positive changes. Living donor kidney recipients mostly accepted the kidney to improve their own quality of life (47%. Donors mostly donated a kidney because transplantation would make the recipient less dependent (25%. After transplantation both positive and negative relationship changes are experienced. Conclusion Expected relationship changes and concerns about the donor’s health lead some kidney patients to wait for a deceased donor, despite having a potential living donor available. Further research is needed to assess whether this concerns a selected group.

    We report the technique of and initial experience with retroperitoneal laparoscopic live donor right nephrectomy for purposes of renal allotransplantation and autotransplantation. A total of 5 patients underwent retroperitoneoscopic live donor nephrectomy of the right kidney for autotransplantation in 4 and living related renal donation in 1. Indications for autotransplantation included a large proximal ureteral tumor, a long distal ureteral stricture and 2 cases of the loin pain hematuria syndrome. In all cases a 3-port retroperitoneal laparoscopic approach and a pelvic muscle splitting Gibson incision for kidney extraction were used. In patients undergoing autotransplantation the same incision was used for subsequent transplantation. All procedures were successfully accomplished without technical or surgical complications. Total mean operating time was 5.8 hours and average laparoscopic donor nephrectomy time was 3.1 hours. Mean renal warm ischemia time, including endoscopic cross clamping of the renal artery to ex vivo cold perfusion, was 4 minutes. Average blood loss for the entire procedure was 400 cc. Radionuclide scan on postoperative day 1 confirmed good blood flow and function in all transplanted kidneys. Mean analgesic requirement was 58 mg. fentanyl. Mean hospital stay was 4 days (range 2 to 8), and convalescence was completed in 3 to 4 weeks. In the occasional patient requiring renal autotransplantation live donor nephrectomy can be performed laparoscopically with renal extraction and subsequent transplantation through a single standard extraperitoneal Gibson incision, thus, minimizing the overall operative morbidity. Furthermore, these data demonstrate that live donor nephrectomy of the right kidney can be performed safely using a retroperitoneal approach with an adequate length of the right renal vein obtained for allotransplantation or autotransplantation.

    Full Text Available Abstract Background The kidneys are essential for the metabolism of vitamin A (retinol and its transport proteins retinol-binding protein 4 (RBP4 and transthyretin. Little is known about changes in serum concentration after living donor kidney transplantation (LDKT as a consequence of unilateral nephrectomy; although an association of these parameters with the risk of cardiovascular diseases and insulin resistance has been suggested. Therefore we analyzed the concentration of retinol, RBP4, apoRBP4 and transthyretin in serum of 20 living-kidney donors and respective recipients at baseline as well as 6 weeks and 6 months after LDKT. Results As a consequence of LDKT, the kidney function of recipients was improved while the kidney function of donors was moderately reduced within 6 weeks after LDKT. With regard to vitamin A metabolism, the recipients revealed higher levels of retinol, RBP4, transthyretin and apoRBP4 before LDKT in comparison to donors. After LDKT, the levels of all four parameters decreased in serum of the recipients, while retinol, RBP4 as well as apoRBP4 serum levels of donors increased and remained increased during the follow-up period of 6 months. Conclusion LDKT is generally regarded as beneficial for allograft recipients and not particularly detrimental for the donors. However, it could be demonstrated in this study that a moderate reduction of kidney function by unilateral nephrectomy, resulted in an imbalance of components of vitamin A metabolism with a significant increase of retinol and RBP4 and apoRBP4 concentration in serum of donors.

    BACKGROUND: A living donor transplant improves the survival and quality of life of a transplant patient. However, the impact of transplantation on postoperative lung function and respiratory muscular strength in kidney donors remains unknown. OBJECTIVE: To evaluate pulmonary function, respiratory muscle strength, quality of life and the incidence of postoperative pulmonary complications (PPCs) in kidney donors undergoing nephrectomy. METHOD: This prospective cohort enrolled 110 consecutive kidney donors undergoing nephrectomy. Subjects underwent pulmonary function (using spirometry) and respiratory muscular strength (using manovacuometry) assessments on the day prior to surgery and 1, 2, 3 and 5 days postoperatively. Quality of life (measured by the SF-36) was evaluated preoperatively and 30 days postoperatively. PPCs were assessed daily by a blinded assessor. RESULTS: Donors exhibited a decrease of 27% in forced vital capacity, 58% in maximum inspiratory capacity and 51% in maximum expiratory pressure on the 1stpostoperative day (p<0.001) but this improved over days 2, 3 and 5 but had not returned to preoperative levels. Patient quality of life was still impaired at 30 days with regards to functional capacity, physical role, pain, vitality and social functioning (p<0.05) but these parameters improved slowly. None of the patients developed PPCs. CONCLUSION: Kidney donors submitted to nephrectomy exhibited a reduction in pulmonary function, respiratory muscular strength and quality of life, most of which were improving toward pre-surgical levels.

    A positive pretransplant flow cytometry cross-match (FC-XM) allows precise identification of high-risk recipients vulnerable to hyperacute or accelerated rejection after transplantation. Living donor kidney transplant recipient candidates with positive cross-match have been successfully treated with a combination of plasmapheresis (therapeutic plasma exchange, TPEX) and intravenous immunoglobulin (IVIG), achieving conversion to negative cross-match and successful transplant. We report the first successful case of simultaneous pancreas kidney transplant (SPKT) from a living donor (LD) performed against an initially positive FC-XM, converted to negative using a protocol based on TPEX and IVIG in combination with antiCD20 monoclonal antibody. This strategy of overcoming the cross-match barriers in living donation may offer a chance of successful transplantation to highly sensitized candidates for SPKT, for whom cadaveric transplant is difficult to achieve.

    Ischemic conditioning involves the delivery of short cycles of reversible ischemic injury in order to induce protection against subsequent more prolonged ischemia. This randomized controlled trial was designed to determine the safety and efficacy of remote ischemic conditioning (RC) in live donor kidney transplantation.This prospective randomized clinical trial, 80 patients undergoing live donor kidney transplantation were randomly assigned in a 1:1 ratio to either RC or to a control group. RC consisted of cycles of lower limb ischemia induced by an arterial tourniquet cuff placed around the patient's thigh. In the RC treatment group, the cuff was inflated to 200 mm Hg or systolic pressure +25 mm Hg for 4 cycles of 5 min ischemia followed by 5 min reperfusion. In the control group, the blood pressure cuff was inflated to 25 mm Hg. Patients and medical staff were blinded to treatment allocation. The primary end-point was renal function measured by estimated glomerular filtration rate (eGFR) at 1 and 3 months posttransplant.Donor and recipient demographics were similar in both groups (P protocol described here, did not improve renal function after live donor kidney transplantation.

    Living-donor liver transplantation (LDLT) is a well-established treatment for end-stage liver disease. Nevertheless, it has not been extensively accepted in North America or Europe as it has been in Asia. At the University of Toronto we initiated our LDLT program in 2000 and since then our program has grown each year, representing today the largest LDLT program in North America. Our right-lobe LDLT experience from 2000-2014 includes 474 right lobes. Only 30% of our grafts have included the middle hepatic vein. We present excellent outcomes in terms of graft and patient survival which is not different to that achieved with deceased donor liver transplantation. In the present study we will discuss the evolution, challenges and current practices of our LDLT program. We will discuss what is and has been the program philosophy. We will also discuss how we evaluate our donors and the extensive workup we do before a donor is accepted for live donation. Furthermore we will discuss some tips and tricks of how we perform the right hepatectomy for live donation.

    To determine the feasibility of volumetric criteria without anatomic exclusion for the selection of right posterior sector (RPS) grafts for adult-to-adult living donor liver transplantation (LDLT), we reviewed and compared our transplant data for RPS grafts and right lobe (RL) grafts. Between January 2008 and September 2010, adult-to-adult LDLT was performed 65 times at our institute; 13 of the procedures (20%) were performed with RPS grafts [the posterior sector (PS) group], and 39 (60%) were performed with RL grafts (the RL group). The volumetry of the 13 RPS donor livers showed that the RPS volume was 39.8% ± 7.6% of the total liver volume. Ten of the 13 donors had to donate RPS grafts because the left liver volume was inadequate. All donor procedures were performed successfully, and all donors recovered from hepatectomy. However, longer operative times were required for the procurement of RPS grafts versus RL grafts (418 ± 40 versus 345 ± 48 minutes, P liver function was smoother for the donors of the PS group versus the donors of the RL group. The RPS grafts had significantly smaller hepatic artery and bile duct openings than the RL grafts. All recipients with RPS grafts survived LDLT. No recipients experienced vascular graft complications or small-for-size graft dysfunction. There were no significant differences in the incidence of posttransplant complications between the donors and recipients of the PS and RL groups. The 3-year graft survival rates were favorable in both groups (100% in the PS group versus 91% in the RL group). In conclusion, the selection of RPS grafts by volume criteria is a feasible strategy for an adult-to-adult LDLT program.

    Transplantation with kidneys from older living donors is on the rise, yet controversy still exists over whether the outcomes are as satisfactory as with kidneys from younger donors. We retrospectively analyzed 1009 living donor kidney transplants performed at our center between 2006 and 2013. Graft and patient outcomes were compared between transplants with kidneys from old living donors (OLD, 55-65 years) (n = 264) and from young living donors (YLD, transplantation was also similar for patients receiving YLD kidneys (98.5%, 97.1%, and 96.7%) and for patients receiving OLD kidneys (99.6%, 99.6%, and 96.8%; P = 0.110). The OLD kidneys were not associated with increased risk of death-censored graft failure (hazard ratio, 2.5; 95% confidence interval, 0.57 to 11.11) and patient death (hazard ratio, 1.67; 95% confidence interval, 0.75 to 3.73). In addition, there is no increased graft loss or patient death for each 10-year increase in donor age. Transplantation with OLD kidneys was not associated with reduced patient or graft outcomes in the short term (≤ 12 months) or medium term (>1 year). Graft and patient outcomes after living-donor kidney transplantation are similar in the short-term and medium-term for donors aged 55 to 65 years and for younger donors. Therefore, the use of OLD kidneys should be encouraged in China.

    Background Because of the lack of brain death laws in China, the proportion of cadaveric organ donation is low. Many patients with end-stage liver disease die waiting for a suitable donor. Living donor liver transplantation (LDLT) would reduce the current discrepancy between the number of patients on the transplant waiting list and the number of available organ donors. We describe the early experience of LDLT in the mainland of China based on data from five liver transplant centers.Methods Between January 2001 and October 2003, 45 patients with end-stage liver disease received LDLT at five centers in China. The indication and timing, surgical techniques and complications, nonsurgical issues including rejection, infection, and advantages of LDLT in the series were reviewed. Actuarial patient and graft survival rates were calculated by using the Kaplan-Meier product-limit estimate. Statistical analysis was completed by using SPSS 10.0.Results All LDLT recipients were cirrhotic patients, except for one man with fulminant hepatic failure. Among the 45 cases of LDLT, 35 (77.8%) were performed in one center (the First Affiliated Hospital of Nanjing Medical University). The overall 1 and 3 year survival rate of the recipients was 93.1% and 92.0%, respectively. Of the 45 LDLT donors, there were 3 cases of biliary leakage, 2 subphrenic collections, 1 fat liquefaction around the incision and 1 biliary peritonitis after T tube removal. All donors recovered completely.Conclusions LDLT provides an excellent approach to addressing the problem of donor shortage in China even though the operation is complicated, uncompromising and difficult with respect to the safety of the donors and receptors. Despite early technical hurdles having been overcome, perfection of technique is still necessarily. At present, LDLT is a good choice for the patients with irreversible liver disease.

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

    It has been observed during the past 10-15 years a greater disparity between the supply of kidneys for transplantation and the demand of patients on waiting lists. The number of cadaveric kidneys available for transplantation have not increased in many countries. Countries and their societies are faced with a choice, let patients with the end- stage renal disease stay on, dialysis giving a faster death and a lower quality of life, or decide to introduce the more active living donation program. There are countries, historically Scandinavian countries, the U.S.A. and U.K., which decided to change medical, social and ethical attitudes to help their citizens and patients on dialysis. For many other countries approval of the new approach of their donation seems to cause difficulties. The main problem for medical staff is the principle Primum non nocere (First do no harm), removal of a living kidney conflicts with this principle. From the other point of view is the human right of an individual to autonomy for donation of a kidney. The donor is completely informed for the risks involved in donation of a kidney to an awaiting recipient. The donors reasons for donation of the kidney must be understood and family pressure excluded. Where is the borderline between the paternalistic approach of the medical personnel preventing the altruistic attitude of the donor? How far is the role of the medical staff to extend in the assessment of the altruistic nature and goodwill of the donors?

    Fulminant hepatitis is fatal in most cases and timely liver transplantation is the only effective treatment.This study evaluates the survival outcomes of patients who underwent living-donor liver transplantation (LDLT)using right lobe liver grafts for fulminant liver failure due to hepatitis B infection.Nine cases of adult right lobe LDLT were performed in our department from September 2002 to August 2005 and the clinical and following-up data were reviewed.According to the pre-transplant Child-Pugh-Turcotte classification,the nine patients were classified as grade C.The model for end-stage liver disease (MELD) score of these patients ranged from 16 to 42.The principal complications before transplantation included abnormal renal function,hepatic coma of different degrees and alimentary tract hemorrhage.The main complications after transplantation included pulmonary infection in two cases,acute renal failure in three cases and transplantation-related encephalopathy in one case.No primary failure of vascular or biliary complications occurred.The one-year survival rate was 55.6%.There were no serious complications or deaths in donors.In general,it is extremely difficult to treat fulminant hepatitis by conservative regimen,particularly,in cases with rapid progresslon.Emergency adult living-donor liver transplantation is an effective treatment for fulminant hepatitis patients and is relatively safe for donors.

    The link between obesity and renal disease is unclear, and there is no consensus as to whether obese individuals are at increased risk for kidney disease after living kidney donation if they otherwise meet acceptance criteria. We retrospectively studied time-zero (implantation) biopsies in 49 obese (body mass index (BMI) > or = 30 kg/m2) and 41 non-obese (BMI < 30 kg/m2) renal donors that met acceptance criteria. We found that our obese donor population had higher systolic blood pressure (P < 0.001 vs non-obese) and higher absolute iothalamate clearance (P = 0.001 vs non-obese) before donation. The obese donors had larger glomerular planar surface area compared to non-obese controls (P = 0.017), and this parameter correlated with patient weight and urinary microalbumin excretion. Detailed examination of the biopsies revealed that although most histologic findings were similar between groups, the obese donors had more tubular dilation (P = 0.01), but less tubular vacuolization (P = 0.02) than the non-obese controls. There was also a trend toward more arterial hyalinosis in the obese patients than controls (P = 0.08). From these data, our studies detected subtle differences in donor organs obtained from obese compared to non-obese individuals. Further studies should be carried out to quantify the long-term impact of these findings.

    Liver transplantation is now an established treatment for children with end-stage liver disease. Left lateral segment (LLS) grafts are most commonly used in split and living donor liver transplantation in children. In very small children, LLS grafts can be too large, and further nonanatomical reduction has recently been introduced to mitigate the problem of large-for-size grafts. However, the implantation of LLS grafts can be a problem in infants and very small children because of the thickness of the grafts, and these techniques do not address problems related to thickness. We herein describe a technique for reducing the thickness of living donor left lateral grafts and successful transplantation in a 2.8-kg infant with acute liver failure.

    BACKGROUND: In right liver living donor liver trans-plantation, hepatic venous anastomosis is performed using the recipient's right hepatic vein oriifce. There may be situations that the portal vein is short or the right liver graft is small, leading to dififculty in portal vein, hepatic artery or duct-to-duct anastomosis. METHODS: The recipient's right hepatic vein oriifce is closed partially for 2 cm at the cranial end or totally, and a new venotomy is made caudal to the right hepatic vein oriifce. Hepatic vein anastomosis is performed with the new venotomy. RESULTS: The distance between the liver graft hilum and hepatoduodenal ligament is reduced. Portal vein, hepatic artery and biliary anastomosis could be performed without tension or conduit. CONCLUSION: Caudal shifting of hepatic vein anasto-mosis facilitates implantation of a right liver living donor graft.

    Full Text Available The aim of this study was to document vascular complications that occurred fol-lowing cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133 with the most frequent being hemorrhage (n = 91; 6.1% followed by allo-graft renal artery stenosis (n = 26; 1.7%, renal artery thrombosis (n = 9; 0.6%, and renal vein thrombosis (n = 7; 0.5%. Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P= 0.017. The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P= 0.033. The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001. Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants.

    In the United States, live organ donation can be a costly and burdensome undertaking for donors. While most donation-related medical expenses are covered, many donors still face lost wages, travel expenses, incidentals, and potential for future insurability problems. Despite widespread consensus that live donors (LD) should not be responsible for the costs associated with donation, little has changed to alleviate financial burdens for LDs in the last decade. To achieve this goal, the transplant community must actively pursue strategies and policies to eliminate unreimbursed out-of-pocket costs to LDs. Costs should be more appropriately distributed across all stakeholders; this will also make live donation possible for people who, in the current system, cannot afford to proceed. We propose the goal of LD "financial neutrality," offer an operational definition to include the coverage/reimbursement of all medical, travel, and lodging costs, along with lost wages, related to the act of donating an organ, and guidance for consideration of medical care coverage, and wage and other expense reimbursement. The intent of this report is to provide a foundation to inform discussion within the transplant community and to advance initiatives for policy and resource allocation.

    Evaluating a person's suitability for living organ donation is crucial, consisting not only of a medical but also of a thorough psychosocial screening. We performed a systematic literature review of guidelines, consensus statements, and protocols on the content and process of psychosocial screening of living kidney and liver donor candidates. We searched PubMed, Embase, CINAHL, and PsycINFO until June 22, 2011, following the PRISMA guidelines, complemented by scrutinizing guidelines databases and references of identified publications. Thirty-four publications were identified, including seven guidelines, six consensus statements, and 21 protocols or programs. Guidelines and consensus statements were inconsistent and lacked concreteness for both their content and process, possibly explaining the observed variability in center-specific evaluation protocols and programs. Overall, recommended screening criteria are not evidence-based and an operational definition of the concept "psychosocial" is missing, causing heterogeneity in terminology. Variation also exists on methods used to psychosocially evaluate potential donors. The scientific basis of predonation psychosocial evaluation needs to be strengthened. There is a need for high-quality prospective psychosocial outcome studies in living donors, a uniform terminology to label psychosocial screening criteria, and validated instruments to identify risk factors.

    In the field of pediatric living donor liver transplantation, the indications for apheresis and dialysis, and its efficacy and safety are still a matter of debate. In this study, we performed a retrospective investigation of these aspects, and considered its roles. Between January 2008 and December 2010, 73 living donor liver transplantations were performed in our department. Twenty seven courses of apheresis and dialysis were performed for 19 of those patients (19/73; 26.0%). The indications were ABO incompatible-liver transplantation in 11 courses, fluid management in seven, acute liver failure in three, renal replacement therapy in two, endotoxin removal in two, cytokine removal in one, and liver allograft dysfunction in one. Sixteen courses of apheresis and dialysis were performed prior to liver transplantation for 14 patients. The median IgM antibody titers before and after apheresis for ABO blood type-incompatible liver transplantation was 128 and eight, respectively (P apheresis and dialysis were performed post liver transplantation for 10 patients. The median PaO2/FiO2 ratio before and after dialysis for fluid overload was 159 and 339, respectively (P apheresis and dialysis occurred. The 1-year survival rate of the patients was 100%. Apheresis and dialysis in pediatric living donor liver transplantation are effective for antibody removal in ABO-incompatible liver transplantation, and fluid management for acute respiratory failure.

    To determine the accuracy of the use of multi-detector row CT (MDCT) to predict vascular anatomy in living kidney donors and to reveal the prevalence of vascular variations in a Korean population. A total of 153 living kidney donors that had undergone preoperative CT and nephrectomy, either with open or laparoscopic surgery, were selected retrospectively. The initial CT results were compared with the surgical findings and repeated review sessions of CT scans were performed to determine the causes of mismatches in discordant cases. The accuracy of CT angiography was 95% to predict the number of renal vessels. Four arteries and two veins were missed during the initial CT interpretation due to perception errors (for two arteries and two veins) and technical limitations (two arteries). The prevalence of multiple renal arteries and veins, early branching of a renal artery and late confluence of a renal vein were 31%, 5%, 12%, 17%, respectively. The circumaortic renal vein and the bilateral inferior vena cava were found in two cases each (1.3%). One case (0.7%) each of a retroaortic renal vein and a supradiaphragmatic originated renal artery were found. MDCT provides a reliable method to evaluate the vascular anatomy and variations of living kidney donors.

    A 20-year-old woman was admitted to an emergency hospital after ingesting 66 g of acetylsalicylic acid in a suicide attempt. Although she was treated with gastric lavage, oral activated charcoal, and intravenous hydration with sodium bicarbonate, her hepatic and renal function gradually deteriorated and serum amylase levels increased. Steroid pulse therapy, plasma exchange, and continuous hemodiafiltration did not yield any improvement in her hepatic or renal function, and she was transferred to our hospital for living donor liver transplantation. Nine days after drug ingestion, she developed hepatic encephalopathy: thus, we diagnosed the patient with acute liver failure with hepatic coma accompanied by acute pancreatitis due to the overdose of acetylsalicylic acid. Living donor liver transplantation was immediately performed using a left lobe graft from the patient's mother. Following transplantation, the patient's renal and hepatic function and consciousness improved, and she was discharged. In this report, we describe a rare case of acetylsalicylic acid-induced acute liver failure with acute hepatic coma and concomitant acute pancreatitis and acute renal failure, which were treated successfully with emergency living donor liver transplantation.

    Skeletal muscle and osteoarticular tissue banks are responsible to procure, process, store and distribute tissues, from living and cadaveric donors. The procedures involve the application of protocols covering all aspects of the banking, ensuring the best tissue quality and maximum safety for the recipient. An analysis on the causes of bone tissue discarded by Biotar Tissue Bank between January 2005 and December 2012 was carried. Bone tissue was obtained from both hip and knee replacement (femoral heads and tibial plateau respectively) in living donors treated at different medical-surgical institutions in Argentina. These tissues were processed at the Bank to produce both frozen and lyophilized cancellous bone. Out of 3413 donated bones received by the Bank, 77.55 % resulted in final product, while the remaining 22.44 % was discarded in compliance with the quality standards of both the Bank and the regulatory authority. Comparing the last and the first year of the studied period, the number of discarded tissue increased 3.6 times, while the number of collected bones was approximately 10 times higher. Related to total disposed tissue, reactive serology was the most frequent cause (62.14 %), followed by inappropriate collection/storage of blood sample (30.81 %). A progressive reduction in the percentages of total discard was observed, and this was proportional to inappropriate collection/storage of blood sample. No significant differences were found in the discard rates due to positive serology throughout all the years studied. The success of a tissue bank requires full commitment of all the personnel especially the team members responsible for donor selection and the processing of allografts. It is important to critically screen donors in the early stages of donor recruitment. All of the procedures carried out by the tissue bank are parts of the quality control system which must be strictly carried out. Biotar Tissue Bank is continuously committed to ensure

  16. Management of the middle hepatic vein and its tributaries in right lobe living donor liver transplantation

    BACKGROUND: Left liver graft from a small donor will not meet the metabolic demands of a larger adult recipient. To overcome the problem of graft size insufifciency, living donor liver transplantation (LDLT) using the right lobe has become a standard method for adult patients. As the drainage of the median sector (segmentsⅤ, Ⅷ andⅣ) is mainly by the middle hepatic vein (MHV), the issue of whether the MHV should or should not be taken with the graft or whether the MHV tributaries (Ⅴ5,Ⅴ8) should be reconstructed in the recipient remains to be settled. DATA SOURCES:An English-language literature search was conducted using MEDLINE (1985-2006) on right lobe living donor liver transplantation, middle hepatic vein, vein graft, hepatic venoplasty and other related subjects. RESULTS: Some institutions had proposed their policy for the management of the MHV and its tributaries. Dominancy of the hepatic vein, graft-to-recipient weight ratio, and remnant liver volume as well as the donor-to-recipient body weight ratio, the volume of the donor's right lobe to the recipient's standard liver volume and the size of MHV tributaries are the major elements for the criteria of inclusion of the MHV, while for the policy of MHV tributaries reconstruction, the proportion of congestive area and the diameter of the tributaries are the critical elements. Optimal vein grafts such as recipient's portal vein and hepatic venoplasty technique have been used to obviate hepatic congestion and venous drainage disturbance. CONCLUSIONS:Taking right liver grafts with the MHV trunk (extended right lobe grafts) or performing the MHV tributaries reconstruction in modiifed right lobe grafts, according to the criteria proposed by the institutions with rich experience, can solve the congestion problem of the right paramedian sector and help to improve the outcomes of the patients. The additional use of optimal vein grafts and hepatic venoplasty also can guarantee excellent venous drainage.

    AIM: To assess the impact of a joint surgical and radiological audit on the accuracy of contrast-enhanced magnetic resonance angiography (MRA) reports in the evaluation of potential renal donors. MATERIALS AND METHODS: We analysed the records of live renal donors who underwent gadolinium-enhanced MRA as part of the pre-operative evaluation to assess renal vasculature between August 1999 and July 2002 when feedback from surgical findings to radiology had been available. In cases of discrepancy between MRA reports and surgical findings, studies were retrieved from the magnetic resonance imaging (MRI) workstation and subjected to detailed joint clinical and radiological review. Scan quality was assessed and sources of discrepancy were identified. RESULTS: There were 45 donors, 23 men and 22 women with a mean age of 41 years. Reported MRA findings were fully confirmed at surgery in 38 of 45 cases. These images were not analysed further. In seven donors the findings at surgery were discrepant with the radiological reports: there were four cases of 'missed' early branches and three cases of 'missed' accessory arteries. In the first year of the audit there were four discrepant cases out of 18 (22%), all of which were radiological reporting errors. The number of discrepant cases in the second year was two out of 19 cases (11%). Neither of these was a radiological reporting error. There was one 'missed' early renal artery branch in the third year of audit, which was identified on MRA review. CONCLUSION: The study highlights the importance of detecting and clearly reporting not only accessory renal arteries, but also early renal arterial branches in the pre-operative evaluation of renal donors. The accuracy of pre-operative MRA in potential renal donors is high, but radiological reporting of MRA examinations is improved through careful clinical feedback, audit and interdisciplinary co-operation.

    Despite increases in the performance of pure laparoscopic living donor hepatectomy, variations in the bile duct or portal vein have been regarded as relative contraindications to this technique [1-3]. This report describes a donor with separate right posterior and right anterior hepatic ducts and portal veins who underwent pure laparoscopic living donor right hemihepatectomy, integrated with 3D laparoscopy and indocyanine green (ICG) near-infrared fluorescence cholangiography [1, 4, 5]. A 50-year-old man offered to donate part of his liver to his older brother, who required a transplant for hepatitis B-associated liver cirrhosis and hepatocellular carcinoma. Donor height was 178.0 cm, body weight was 82.7 kg, and body mass index was 26.1 kg/m(2). Preoperative computed tomography and magnetic resonance cholangiopancreatography showed that the donor had separate right posterior and right anterior hepatic ducts and portal veins. The entire procedure was performed under 3D laparoscopic view. Following intravenous injections of 0.05 mg/kg ICG, ICG near-infrared fluorescence camera was used to demarcate the exact transection line and determine the optimal bile duct division point. The total operation time was 443 min; the donor required no transfusions and experienced no intraoperative complications. The graft weighed 1146 g with a graft-to-recipient weight ratio of 1.88%. The optimal bile duct division point was identified using ICG fluorescence cholangiography, and the bile duct was divided with good patency without any stricture. The right anterior and posterior portal veins were transected with endostaplers without any torsion. The patient was discharged on postoperative day 8, with no complications. Using a 3D view and ICG fluorescence cholangiography, pure 3D laparoscopic living donor right hemihepatectomy is feasible in a donor with separate right posterior and right anterior hepatic ducts and portal veins.

    In living donor liver transplantation (LDLT), the essential aims are to provide an adequate graft volume to the recipient and to keep a sufficient remnant liver volume in the donor. In some instances, these aims cannot be met by a single donor and LDLT using dual grafts from two donors is a good solution. From 2002 to 2009, five recipients in our hospital received dual graft LDLT. Two recipients received one right lobe and one left lobe grafts; the other three received two left lobe grafts. The mean final liver regeneration rate was 91.2%. Left lobe graft atrophy in the long term was observed in recipients who received a right and a left lobe grafts. The initial bigger volume graft in all recipients was noted to have better regeneration than the smaller volume grafts. Portal flow and bilateral grafts volume size discrepancy were considered as two major factors influencing graft regeneration in this study. We also noted that the initial graft volume correlated with portal flow in the separate grafts and finally contribute to individual graft regeneration. Because of compensatory hypertrophy of the other graft, recipients who experienced atrophy of one graft did not show signs of liver dysfunction.

    2009-01-01

    BACKGROUND: In liver transplantation, acute cellular rejection (ACR) is still a major complication that can lead to mortality. Bile secretion has been considered as a marker of early graft function. METHODS: The study included 41 adults who received living donor liver transplantation (LDLT) at Kyoto University Hospital between April 2007 and February 2008. The patients were stratified according to the presence or absence of ACR. Bile samples were collected from donors once and from recipients every other day for the first 2 weeks after transplantation. Total bile acid (BA) and taurine-conjugated bile acid (TCBA) in bile were measured by magnetic resonance spectroscopy. The recipient/donor (R/D) BA ratio and R/D TCBA ratio were calculated. RESULTS: The ACR group (n=12) showed a greater decrease in BA post-transplantation than the non-ACR group, but this difference was not statistically significant. On both day 7 and day 9 post-transplantation the R/D TCBA was significantly different between the two groups (P=0.038 on day 7 and P=0.036 on day 9). The R/D TCBA ratio ≥0.5 on days 7 and 9, and ≥0.38 on day 11 post-transplantation were associated with better ACR-free survival. CONCLUSION: The recipient/donor TCBA ratio can be a predictor for ACR after LDLT as early as post-transplantation day 7.

    Full Text Available Background: Although the psychological assessment of potential living kidney donors (PLKD is part of the recommendations for action for any transplant coordination, there are not many studies that provide data about the importance of selecting donors for improving transplant outcomes. This work aims to raise awareness of potential kidney donors by designing methods for early detection of potential problems after the transplant, as well as by selecting the most suitable donors.Methods: This is a study of 25 PLKD drawn from the General University Hospital of Alicante. Participants completed the Millon Clinical Multiaxial Inventory (MCMI-III for the study of personality characteristics.Results: Women scored higher than men in the compulsive personality scale, and individuals with a genetic link with the recipient scored higher on depressive and dependent scales than did those with other relationships (emotional or altruistic.Conclusions: Women showed a pattern of significantly more compulsive personality traits (cautious, controlled, perfectionist within a non-pathological style. Among the PLKD, there were significantly more women, which is contrary to what typically happens with donations from cadavers. Genetically related subjects scored higher on depression than did those that were emotionally related. The personality assessment of candidates for PLKD can help with developing a post-transplant follow-up regimen for an improved quality of life.

    To evaluate the effects of intermittent hepatic inflow occlusion (IHIO) during donor hepatectomy for living donor liver transplantation (LDLT) in recipients and donors, we performed a single-center, open-label, prospective, parallel, randomized controlled study. Adult donor-recipient pairs undergoing LDLT with right hemiliver grafts were randomized into IHIO and control groups (1:1). In the IHIO group, IHIO was performed during donor hepatectomy. The primary endpoint was the peak serum alanine aminotransferase (ALT) concentration in the recipients within 5 days after the operation. Blood samples for measurements of interleukin-6 (IL-6), IL-8, tumor necrosis factor α (TNF-α), and hepatocyte growth factor (HGF) were taken from the donors and the recipients during the operation and postoperatively. Biopsy samples for measurements of caspase-3 and malondialdehyde (MDA) were taken from the donors and the recipients. In all, 50 donor-recipient pairs (ie, 25 pairs in each group) completed this study. The mean peak serum ALT levels within 5 days after the operation did not differ in the recipients between the 2 groups (P = 0.32) but were higher in the donors of the IHIO group (P = 0.002). There were no differences in the prothrombin times or total bilirubin levels in the recipients or donors between the 2 groups. The amount of blood loss during donor hepatectomy was significantly lower in the IHIO group versus the control group (P = 0.02). The mean hospital stay for donors was 19.3 ± 7.2 days in the control group and 15.8 ± 4.6 days in the IHIO group (P = 0.046). There were no in-hospital deaths within 1 month and no cases of primary nonfunction or initially poor function in the 2 groups. The concentrations of IL-6, IL-8, TNF-α, and HGF did not differ between the 2 groups, nor did the concentrations of caspase-3 and MDA. In conclusion, although we found differences in postoperative peak serum ALT levels in donors, donor hepatectomy with IHIO for LDLT using a right

    Full Text Available The worldwide shortage of organs available for transplantation has led to the use of living-unrelated kidney donors. In this context, spouses represent an important source of organ donors. We compared the allograft outcomes of spousal donor transplantation (SDT with anti-thymocyte globulin (ATG induction therapy and living related donor transplantation (LRDT with triple immonosuppression and basiliximab, in addition. Among the 335 living and deceased donor kidney transplantations performed between April 2001 and June 2010, there were 274 living donor kidney transplantations including 34 SDT and 240 LRDT. The minimum follow-up period was 36 months. All recipients of SDT received ATG (1.5 mg/kg induction therapy, which was stopped five to seven days after surgery. Maintenance immunosuppression included tacrolimus (TAC, mycophenolate mofetil (MMF and prednisolone. LRDT recipients received triple immunosuppressive protocol consisting of cyclosporine or TAC, MMF and prednisolone, in addition to basiliximab. There was a significant difference between the two groups in recipient age, while pre-operative duration on dialysis, recipient sex and donor age and sex were not significantly different. There was also a significant difference between the two groups in the number of human leukocyte antigen (HLA mismatches. The 1-, 3- and 5-year graft survival rates of SDT were 94.1%, 88.2% and 79.4%, respectively, and the frequency of acute rejection episodes was 5.8% (two cases. The 1-, 3- and 5-year graft survival rates of LRDT were 95.8%, 91.6% and 83.3%, respectively, with the frequency of acute rejection being 16.2%. The graft survival rates of SDT were as good as LRDT, while the acute rejection rates in SDT were lower than in LRDT, although the difference was not statistically different (P = 0.13.

    The severe organ shortage in Israel has prompted many patients to undergo kidney transplantation abroad. In May 2008, the Israeli Knesset approved the Israel Transplant Law prohibiting organ trade and disallowing health insurers to reimburse the cost of illegal transplantation abroad. The aim of this study was to assess the initial effect of the law on kidney transplantations inside and outside the country. The number of kidney transplantations performed inside and outside Israel was compared between the 3-year periods before and after implementation of the transplant law (2006-2008 and 2009-2011). Further analysis compared the number of deceased-donor and live-donor transplantations performed in Israel during the same periods. The results showed that the number of transplants performed abroad dropped significantly, from a median of 143 per year during 2006-2008 to Israel Transplant Law has dramatically affected kidney transplantation practices in Israel by reducing transplantation tourism and increasing living-donor kidney transplantations.

    Full Text Available There are no reports of cystic liver infection after liver transplantation. Herein, we report a rare case of cystic liver graft infection after living donor liver transplantation (LDLT. The patient was a 24-year-old man with primary sclerosing cholangitis who underwent right lobe graft LDLT. Preoperative abdominal computed tomography (CT revealed a liver cyst at segment 8 of the donor liver. Biliary reconstruction was performed with hepaticojejunostomy. The postoperative course was uneventful until the patient developed a high fever and abdominal pain 15 months after LDLT. Abdominal contrast CT revealed abscess formation. Percutaneous drainage of the cyst was performed and purulent liquid was drained. The fever gradually subsided after treatment. On follow-up CT, the size of the infected liver cyst was decreased. Clinicians should be aware of the potential for cystic liver infection when using grafts with liver cysts, particularly when biliary reconstruction is performed with hepaticojejunostomy.

    BACKGROUND:Infectious complications are common during the postoperative course of a liver transplant recipient. Malaria, however, is a rare complication in such a setting. METHOD:We report post-transplantation malaria causing elevation of liver enzymes in two recipients. RESULTS:Both patients who had undergone living donor liver transplantation showed elevated levels of liver enzymes and fever during the postoperative course. Investigations (including liver biopsy in one patient) were initially inconclusive in determining the cause of liver dysfunction. The diagnosis of malaria was established in both cases by peripheral blood smear. Liver function transiently worsened with antimalarial treatment but subsequently became normal. CONCLUSION:This report highlights the importance of excluding such uncommon causes of post-transplantation liver dysfunction, especially when either the recipient or the donor comes from a region endemic for malaria.

    Background Optimal treatment for established renal failure is living donor kidney transplantation. However this pathway exposes healthy individuals to significant reduction in nephron mass via major surgical procedure. Laparoscopic donor nephrectomy is now the most common method for live donor transplantation, reducing both donor post-operative pain and recovery time. However this procedure exposes kidneys to additional haemodynamic stresses. It has been suggested that donor hydration—particu...

    Infantile Refsum disease (IRD) is a rare autosomal recessive disorder of peroxisome biogenesis characterized by generalized peroxisomal metabolic dysfunction, including accumulation of very long-chain fatty acids (VLCFAs) and phytanic acid (PA), as well as decreased plasmalogen contents (PL). An effective therapy for this intractable disease has not been established, and only supportive management with docosahexaenoic acid supplementation and low PA diet has been reported so far. A boy of 3 years and 8 months presented with facial dysmorphism, transaminitis, and psychomotor retardation. Biochemical analysis showed elevated PA and VLCFAs, with reduced PL in the serum. Immunofluorescence study of fibroblasts from the patient indicated a mosaic pattern of catalase-positive and -negative particles, and molecular analysis revealed compound heterozygous mutations of PEX6 The failure of medical management to prevent the progression of clinical symptoms and abnormal biochemistry prompted us to consider liver transplantation (LT). With the chances of receiving a deceased donor liver being poor, we performed a living-donor LT from the patient's heterozygous mother. At 6-month follow-up, the patient's serum PA levels had normalized. VLCFAs and PL levels had declined and increased, respectively. To the best of our knowledge, this is the second reported case in which IRD was treated by living-donor LT by using a heterozygous donor. Only long-term follow-up will reveal if there is any clinical improvement in the present case. With the liver being a major site for peroxisomal pathways, its replacement by LT may work as a form of partial enzyme therapy for patients with IRD.

    Background: Computed tomographic angiography has become the standard evaluating method of potential living renal donors in most centers. Although incidence of fibromuscular dysplasia is low (3.5-6%), this pathology may be relevant for success of renal transplantation. The incidence of FMD in our population of LRD and reliability of CTA for detecting vascular pathology were the aims of this study. Materials and methods: 101 living renal donors, examined between 7/2004 and 9/2008 by CTA, were included in a retrospective evaluation. The examinations were carried out using a 64 Multi-detector CT (Siemens Medical Solutions, Erlangen). The presence or absence of the characteristic signs of fibromuscular dysplasia, as 'string-of-beads' appearance, focal stenosis or aneurysms, were assessed and graded from mild (=1) to severe (=3). Furthermore, vascular anatomy and arterial stenosis were investigated in this study. Retrospective analysis of CTA and ultrasound were compared with operative and histological reports. Results: Four cases of fibromuscular dysplasia (incidence 3.9%) in 101 renal donors were diagnosed by transplanting surgeons and histopathology, respectively. Three cases could be detected by CTA. In one donor even retrospective analysis of CTA was negative. Ten accessory arteries, 14 venous anomalies and 12 renal arteries stenosis due to atherosclerosis were diagnosed by CTA and could be confirmed by the operative report. Conclusion: CTA is sufficient for detection of hemodynamic relevant stenosis and vascular anatomy. Only one patient with a mild form of FMD was under estimated. Therefore, if the CTA shows slightest irregularities which are not typical for atherosclerotic lesions, further diagnostic work up by DSA might still be necessary.

    Background It is difficult and challenging to reconstruct hepatic venous outflow in adult right lobe living donor liver transplantation (LDLT) without the middle hepatic vein (MHV). Excessive perfusion of the portal vein and venous outflow obstruction will lead to acute congestion of the graft, ultimately resulting in primary nonfunction. Although various reconstruction patterns have been explored in many countries, there is currently no clear consensus. In this study we describe a technique to prevent "chocking" of the graft at the outflow anastomosis with the inferior vena cava (IVC) in LDLT using right lobe graft without the MHV.Methods A retrospective analysis was conducted on clinical data from 55 recipients undergoing LDLT using right lobe grafts without the MHV or reconstruction of hepatic venous outflow. The donor's right hepatic vein (RHV) was anastomosed with a triangular opening of the recipient IVC; the inferior right hepatic vein (IRHV), if large enough, was anastomosed directly to the IVC. The great saphenous vein (GSV) was used for reconstruction of significant MHV tributaries.Results No deaths occurred in any of the donors. Of the 55 recipients, complications occurred in 6, including hepaticvein stricture (1 case), small-for-size syndrome (1), hepatic artery thrombosis (1), intestinal bleeding (1), bile leakage (1),left subphrenic abscess and pulmonary infection (1). A total of three patients died, one from small-for-size syndrome and two from multiple system organ failure.Conclusions The multiple-opening vertical anastomosis was reconstructed with hepatic vein outflow. This technique alleviates surgical risk of living donors, ensures excellent venous drainage, and prevents vascular thromboses and primary nonfunction.

    Full Text Available Introduction: The options available to CKD 5 patients with donor shortage due to incompatibilities is to either get enlisted in cadaver transplant program or opt for three other alternatives viz; ABO-incompatible transplant (ABO-I, ABO-incompatible transplant with Rituximab (ABO-R or paired-kidney exchange transplant (PKE. At our institute we have performed ABO-I, ABO-R and PKE transplants and we are presenting the results of these transplants performed at our institution. Here, we report our experiences of living donor kidney transplantation in highly sensitized patients. Objective: To review the options available to CKD 5 patients with incompatible donor. Materials and Methods: Between January 2008 and June 2011, 7 PKE, 26 ABO-I and 7 ABO-R transplants were carried out at our institute. Evaluation of both the recipients and donors involved biochemical, serological and radiological investigations. In case of PKE, recipients were operated simultaneously in different operation theaters. In ABO-I splenectomy was done while in ABO-R was given. Post-transplant the recipient management protocol remained the same. Expenditure following each transplant was calculated. Results: The graft and patient survival of ABO-I, ABO-R and PKE transplants 12-18 months after transplant were 78.9%:80%, 85.7%:85.7% and 100%:100%, respectively. Conclusions: The inclusion of Rituximab in the transplant protocol appears promising. The existing donor shortage could be addressed by encouraging other options like PKE. The limiting factor for ABO-R and PKE transplants is time and cost, respectively. The decision depends on the informed consent between the patient and the nephrologists.

    To study the impact of parent-to-child transplant and older donor age on recipients' post-transplant creatinine levels, a total of 236 patients who received living donor kidney transplantation were evaluated for kidney viability based on creatinine (Cr) level. Of the 236 pairings, 113 (48%) were parent-to-child followed by sibling transplants (66, 30%). Recipient Cr levels were significantly higher at 6 months and 3 years post-transplant in the parent-to-child transplants compared to other donor-recipient relationships. In addition, donor age (average age: 44.1 ± 11.5; range: 19-66) contributed to higher recipient post-transplant Cr levels (p parent-to-child transplant and older donor significantly increased the risk of elevated post-transplant Cr levels in recipients with an estimated odds ratios ranging from 3.46 (95% CI: 1.71-6.98) at 6 months to 8.04 (3.14-20.56) at 3 years post-transplant. Donor age significantly affected transplant survival as measured by higher recipient post-transplant Cr levels. In addition, parent-to-child transplant pairings, along with older donor age, significantly increased the risk of elevated post-transplant Cr levels in recipients.

    Full Text Available To determine the incidence and determinants of delayed graft function due to post-transplant acute tubular necrosis in live related donor renal transplantation. This is a retrospective study of 337 recipients of live related donor renal graft performed between1986 and 2006. Of these recipients, 24 (7.1% subjects developed delayed graft function with no evidence of acute rejection, cyclosporin toxicity, vascular catastrophe or obstructive cause and had evidence of acute tubular necrosis (ATN Group. These subjects were compared with recipients (n= 313, 92.9% who had no clinical or biochemical evidence of ATN. Mean age, and gender distribution of recipients was similar in the two groups (ATN group 35.7 ± 8.3, non-ATN group 34.3 ± 7.5, P= 0.43. Gender distribution of the recipients (men 279, 89.1% vs. 21, 87.5%, P= 0.80 as well as donors (women 221, 70.6% vs. 18, 75.0%, P= 0.75 was also similar. In ATN group as compared with non-ATN group the donor age was significantly greater (56.6 ± 8.3 vs. 46.6 ± 11.2 years, P< 0.0001. There was marginal difference in pre-operative systolic BP (154.5 ± 18.3 vs. 147.4 ± 20.2 mm Hg, P= 0.077 and significant difference in diastolic BP (87.8 ± 9.5 vs. 83.4 ± 11.4 mmHg, P= 0.041. Incidence of multiple renal arteries was similar (16.7% vs. 7.3%, P= 0.22. The warm ischemia time was significantly greater in ATN group (33.3 ± 6.2 min as compared to non-ATN group (30.4 ± 5.7 min, P= 0.042. Duration of hospital stay was more in ATN group (19.9 ± 6.7 vs. 16.8 ± 8.4 days, P= 0.04 but there was no difference in 1 year survival (284 subjects, 90.7% vs. 21 subjects, 87.5%, P= 0.873. This study shows that greater donor age, higher baseline diastolic BP and greater warm ischemia time are major determinants of delayed graft function due to acute tubular necrosis after related donor renal transplantation.

    Full Text Available Kidney transplantation from living kidney donors (LKDs because of its good results represents a good option for the treatment of patients with the end-stage renal disease. Kidney donation is a relatively safe procedure according to several studies. We conducted this cross-sectional study in order to describe the demographic, clinical, and renal outcome of LKD in Cτte d′Ivoire. From March to November 2014, LKD residing in Cτte d′Ivoire at the time of investigation and having donated the kidney more than one year ago were considered for the study. They were evaluated through a questionnaire. Of the 29 LKD listed in Cτte d′Ivoire, only 14 responded to the questionnaire. The mean age at donation was 43.29 ± 9.12 years (27-59 and 10 of the LKD were women. Eight were related to the recipients, and the remaining were spouses. Laparoscopic nephrectomy was performed in nine LKD. The left kidney was harvested in ten cases. The main motivation for donation in all donors was the desire to save a life. At the time of the survey, the average duration after the donation was 4.57 ± 2.56 years (1-8. Only five donors had a regular nephrological follow-up. Hypertension was observed in one donor, seven had significant proteinuria, and six had glomerular filtration rate 30 mL/min. Significantly higher proteinuria was noted in donors under 45 years as compared to those over 45 years (0.43 ± 0.17 g/24 h vs. 0.22 ± 0.03 g/24 h, P = 0.01. Our study suggests that renal disease in LKD in Cτte d′Ivoire is low after a mean follow-up period of four years. A donor registry is essential to ensure better follow-up of donors in order to detect potential adverse effects of kidney donation in the medium as well as in the long-term.

    Full Text Available Objective : The study was performed with an aim to determine the incidence of ureteric complications in live related donor renal transplantation, and to study the effect of ureteric complications on long term graft and patient survival. Patients And Methods: Records of 1200 consecutive live related renal transplants done from 1989-2002 were reviewed. Twenty-six ureteric complications were noted to occur and treatment modalities employed were documented. In the non complication group sufficient data for evaluation was available in 867 patients. Survival analysis were performed using Kaplan-Meier techniques. Results: The overall incidence of urological complications is 2.9%. Complications occurred at a mean interval of 31.9 days after renal transplantation. Ureteric complications occurred in 2% patients with stented and 7.7% patients with non stented anastomosis (p=0.001. Mean follow up following renal transplantation was 37.4 months. Survival analysis showed that ureteric complications did not increase the risk of graft fai lu re or patient death. Conclusions: Ureteric complications in live related donor renal transplantation occurred in 2.9 % patients and did not impair graft and patient survival.

    Screening of living kidney donors may require scintigraphy to split glomerular filtration rate (GFR). To determine the usefulness of computed tomography (CT) to split GFR, we compared scintigraphy-split GFR to CT-split GFR. We evaluated CT-split GFR as a screening test to detect scintigraphy-split GFR lower than 40 mL/min/1.73 m{sup 2}/kidney. This was a monocentric retrospective study on 346 potential living donors who had GFR measurement, renal scintigraphy, and CT. We predicted GFR for each kidney by splitting GFR using the following formula: Volume-split GFR for a given kidney = measured GFR*[volume of this kidney/(volume of this kidney + volume of the opposite kidney)]. The same formula was used for length-split GFR. We compared length- and volume-split GFR to scintigraphy-split GFR at donation and with a 4-year follow-up. A better correlation was observed between length-split GFR and scintigraphy-split GFR (r = 0.92) than between volume-split GFR and scintigraphy-split GFR (r = 0.89). A length-split GFR threshold of 45 mL/min/1.73 m{sup 2}/kidney had a sensitivity of 100 % and a specificity of 75 % to detect scintigraphy-split GFR less than 40 mL/min/1.73 m{sup 2}/kidney. Both techniques with their respective thresholds detected living donors with similar eGFR evolution during follow-up. Length-split GFR can be used to detect patients requiring scintigraphy. (orig.)

    Even though the majority of living kidney donor candidates appear in good mental health and show few concerns little is known concerning the influence of the type of donor-recipient relationship on donor candidates' specific concerns with regard to kidney donation. 136 donor candidates at Virgen del Rocío University Hospital of Seville filled in the Scale of Concerns Regarding Living Kidney Donation of whom 105 donor candidates and their corresponding recipients (105 patients with End-Stage Renal Disease) were further evaluated with regard to mental health (Hospital Anxiety and Depression Scale, Beck Depression Inventory-II) and quality of life (SF-36 Health Survey). As hypothesized recipients scored higher on depression and lower on quality of life. Donor candidates intending to donate to their children were significantly less concerned about risks of donation for themselves compared to donor candidates donating to siblings. Our findings highlight the importance of the type of donor-recipient relationship to understand specific concerns of donor candidates and optimize psychosocial assessment and support. From an evolutionary perspective parents lack of concern about their own well-being can be seen as an altruistic behavior to increase children's fitness at the (potential) expense of their own fitness.

    In 2007, the Regulation on Human Organ Transplantation was enacted in China requiring the establishment of ethics committees to oversee living donor organ transplantation and establishing specific requirements that must be met. We established an Ethics Committee on Organ Transplantation at Peking University Third Hospital, and described its composition, its methods and operating procedures in the examination and approval of living-related donor kidney transplantation (LRDKT) and our initial experience. All 60 proposed cases of LRDKT were presented to the Ethics Committee for discussion, among which 53 cases were approved and seven cases were disapproved due to a variety of reasons that are discussed. The Ethics Committee on Organ Transplantation plays an important role in the ethical oversight of living-related donor organ transplantation in order to ensure to the greatest extent possible the safety, rights and interests of donors and recipients.

    Although severely steatotic liver grafts are not suitable for transplantation, they have been used when other, more optimal donors were not available, especially for living donor liver transplantation (LDLT) using two liver grafts. Here we present two cases of dual-graft LDLT in which the recipients showed rapid and complete clearing of fat from livers with previously severe steatosis. In the first case, two left lateral segment grafts were used, one of which was 70% steatotic. Preoperative and posttransplant two-week liver-to-spleen computed tomography-value (L/S) ratios were 0.48 and 1.25, respectively. A liver biopsy taken two weeks after transplantation showed that the fatty changes had almost disappeared. The second case used one left lobe and one left lateral segment graft, the latter of which was 80% steatotic. Preoperative and two-week L/S ratio were 0.58 and 1.34, respectively, and a liver biopsy taken two weeks after transplantation showed less than 3% steatosis. The two donors of the severely steatotic liver grafts recovered uneventfully. These findings show that the fat content of the liver grafts was rapidly removed after transplantation. This observation is helpful in understanding the recovery sequences following transplantation of steatotic liver grafts, as well as expanding the acceptability of steatotic liver grafts.

    Full Text Available PURPOSE: To evaluate by impression cytology (IC the corneal surface of live limbal tissue donor eyes for autograft or allograft limbal stem cell transplantation (LSCT. METHODS: Twenty limbal donors were enrolled (17 for autograft LSCT and 3 for allograft. Impression cytology was performed before transplantation of superior and inferior limbal grafts and after the third postoperative month. RESULTS: Impression cytology analysis showed sheets of corneal epithelial cells and goblet cell absence beyond the edge of the keratectomy sites in all patients, suggesting that conjunctival invasion towards the center did not occur in any eye. Partial conjunctivalization within 2 to 3 clock hours, confirmed by the presence of goblet cells, was limited to the keratectomy site in 10% of the cases. CONCLUSION: A clear central corneal surface was demonstrated in all eyes following surgery leading to the conclusion that limbal donation was a safe procedure in this group of patients. A small percentage of eyes can have donor sites re-epithelized with conjunctival cells at the periphery of the cornea.

    One hundred consecutive patients receiving related donor kidneys were analyzed in regards to graft and patient survival, morbidity, mortality, histocompatibility and rehabilitation. The average followup was 3 years and 2 months with a minimum post transplant evaluation of one year. Donor morbidity was minimal and the mortality nil. Recipient mortality was 17%, all of which occurred after the first two post transplant months. The most serious life threatening complications after transplantation were due to infection. The greatest morbidity was secondary to aseptic necrosis. The overall graft survival at one year was 94%, 2 years--87%, 3 years--81% and 4 and 5 years--72%. Separation of patients according to tissue typing revealed 95% of recipients with A and B matched kidneys to be alive 5 years later compared to 55% of patients receiving C and D matched kidneys. Rehabilitation was good to excellent in 76% of the living patients and poor in only 4%. These results suggest related donor renal transplantation to be the treatment of choice for patients with chronic renal failure excluding only those individuals who are exceptionally high risks in terms of morbidity and mortality.

    Post-transplantation hypertension is very common and is associated with cardiovascular complications and poor graft survival in kidney transplant recipients. This study aimed to identify risk factors for hypertension after living donor kidney transplantation. We retrospectively analyzed patients who underwent renal transplantation between January 2009 and April 2012. Hypertension was defined as the use of antihypertensive medications at 12 months post-transplantation. Student t test and chi-squared test were performed for univariate analysis. Logistic regression analysis was performed for multivariate analysis. Five-hundred thirty-nine patients were enrolled in the analyses. The rate of antihypertensive medication use was 67% at 12 months. In multivariate analysis, male gender (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.55-4.61), pretransplantation hypertension (OR, 4.65; 95% CI, 2.14-10.11), donor hypertension (OR, 3.23; 95% CI, 1.05-9.96), high body mass index (BMI; OR, 1.21; 95% CI, 1.12-1.29), and use of cyclosporine (OR, 2.05; 95% CI, 1.28-3.27) were associated with post-transplantation hypertension. These data show that male recipient, hypertension before transplantation, donor hypertension, high BMI, and cyclosporine use were independent factors associated with hypertension. It would be useful to predict and prevention the hypertension after kidney transplantation. Copyright © 2016 Elsevier Inc. All rights reserved.

    The incidence of biliary complications after living donor adult liver transplantation (LDALT) is still high due to the bile duct variation and necessity reconstruction of multiple small bile ducts. The current surgical management of the biliary variants is unsatisfactory. We evaluated the role of a new surgical approach in a complicated hilar bile duct variant (Nakamura type IV and Nakamura type II) under emergent right lobe LDALT for high model for end-stage liver disease score patients. The common hepatic duct (CHD) and the left hepatic duct (LHD) of the donor were transected in a right-graft including short common trunks with right posterior and anterior bile ducts, whereas the LHD of the donor was anastomosed to the CHD and the common trunks of a right-graft bile duct and the recipient CHD was end-to-end anastomosed. Ten of 13 grafts (Nakamura types II, III, and IV) had two or more biliary orifices after right graft lobectomy; seven patients had biliary complications (53.8%). Later, the surgical innovation was carried out in five donors with variant bile duct (four Nakamura type IV and one type II), and, consequently, no biliary or other complications were observed in donors and recipients during 47-53 months of follow-up; significant differences (P right hepatic ducts in a complicated donor bile duct variant may facilitate biliary reconstruction and reduce long-term biliary complications.

    Full Text Available The aim of this study is to report the experience from a single center in Libya, on the prevailing live-related kidney transplantation program. The results of three years work on kidney transplantation at the Tripoli Central Hospital (National Organ Transplant Program in Libya were evaluated. The transplant program was launched on 17 th August, 2004 and 135 patients have been transplanted since then till 17 th August, 2007. All donors and recipients were screened thoroughly prior to transplant and monitored closely in the post-transplant period. Our immuno-suppressive protocol was cyclosporine-based. Among the 135 accepted pairs, donors and reci-pients were genetically-related in 133 cases (98.5% and emotionally-related in two others. The mean donor age was 37 ± 9.5 years (range 18-56 years and recipient age 37 ± 13.6 years (range 7-67 years. There were 95 males (70.4% and 40 females (29.6% among the recipients while among the donors, there were 102 males (75.6% and 33 females (24.4%. Delayed graft function was seen in three patients (2.2%, acute rejection in six (4.4%, post-transplant urinary tract infection in six (4.4%, pneumonia in three (2.2%, ureteric kink in two (1.5% and urine leak in four (3.0%. Graft survival at 36 months was 93.3% while patient survival at the same period was 96.3%. This report indicates that the results of our transplant program are good and comparable with other international programs.

    Full Text Available There are two approaches to laparoscopic donor nephrectomy: standard laparoscopic donor nephrectomy (LDN and hand-assisted laparoscopic donor nephrectomy (HALDN. In this study we report the operative statistics and donor complications associated with LDN and HALDN from large-center peer-reviewed publications. Methods. We conducted PubMed and Ovid searches to identify LDN and HALDN outcome studies that were published after 2004. Results. There were 37 peer-reviewed studies, each with more than 150 patients. Cumulatively, over 9000 patients were included in this study. LDN donors experienced a higher rate of intraoperative complications than HALDN donors (5.2% versus. 2.0%, <.001. Investigators did not report a significant difference in the rate of major postoperative complications between the two groups (LDN 0.5% versus HALDN 0.7%, =.111. However, conversion to open procedures from vascular injury was reported more frequently in LDN procedures (0.8% versus 0.4%, =.047. Conclusion. At present there is no evidence to support the use of one laparoscopic approach in preference to the other. There are trends in the data suggesting that intraoperative injuries are more common in LDN while minor postoperative complications are more common in HALDN.

    Chronic kidney disease is one of the main public health concerns in Sri Lanka. In comparison with dialysis, successful kidney transplantation improves both patient survival and quality of life, relieves the burden of dialysis in patients suffering from end-stage renal disease and decreases the cost of healthcare to the society and government. The objective of this retrospective cohort study was to evaluate graft and patient survival rates in patients who were transplanted from living donors at the Nephrology Unit of the National Hospital of Sri Lanka from January 2005 to January 2011. Data were collected using an interviewer-administered questionnaire and through a review of past medical records. The Kaplan-Meier method was used to determine the survival rate, the log rank test was used to compare survival curves and the Cox proportional hazard model was used for multivariate analysis. Mean follow-up was 26.44±16.6 months. The five-year death-censored graft survival of kidney transplant recipients from living donors in our center was 93.5% and the five-year patient survival was 82.2%, which is comparable with other transplant programs around the world. The number of acute rejection episodes was an independent risk factor for graft survival. Delayed graft function, younger recipient age and unknown cause of end-stage renal disease were found to be risk factors for graft failure but after adjusting for confounding factors, and the difference was not apparent.

    Full Text Available Aims. To examine the outcome of potential live kidney donors (PLKD assessment program at Christchurch Hospital and, also, to review findings of Computed Tomographic (CT renal angiograms that led to exclusion in the surgical assessment. Methods. Clinical data was obtained from the database of kidney transplants, Proton. Radiological investigations were reviewed using the hospital database, Éclair. The transplant coordinator was interviewed to clarify information about PLKD who did not proceed to surgery, and a consultant radiologist was interviewed to explain unfavorable findings on CT renal angiograms. Results. 162 PLKD were identified during the period January 04–June 08. Of those, 65 (40% proceeded to have nephrectomy, 15 were accepted and planned to proceed to surgery, 13 were awaiting further assessment, and 69 (42.5% did not proceed to nephrectomy. Of the 162 PLKD, 142 (88% were directed donors. The proportion of altruistic PLKD who opted out was significantly higher than that of directed PLKD (45% versus 7%, P=0.00004. Conclusions. This audit demonstrated a positive experience of live kidney donation at Christchurch Hospital. CT renal angiogram can potentially detect incidental or controversial pathologies in the kidney and the surrounding structures. Altruistic donation remains controversial with higher rates of opting out.

    Heme Oxygenase-1 and its product biliverdin/bilirubin have been demonstrated to protect against ischemia/reperfusion injury (IRI). We investigated whether increased preoperative bilirubin values of transplant recipients decrease IRI. Preoperative bilirubin levels of live donor liver recipients were correlated to postoperative liver transaminase as a marker of IRI. Additionally, two recipient groups with pretransplant bilirubin levels >24 μmol/l (n = 348) and ≤24 μmol/l (n = 118) were compared. Post-transplant liver function, complications, length of hospital stay, and patient and graft survival were assessed. Preoperative bilirubin levels were negatively correlated to the postoperative increase in transaminases suggesting a protective effect against IRI. The maximal rise of ALT after transplantation in high versus low bilirubin patients was 288 (-210-2457) U/l vs. 375 (-11-2102) U/l, P = 0.006. Bilirubin remained a significant determining factor in a multivariate linear regression analysis. The MELD score and its individual components as a marker of severity of chronic liver disease were significantly higher in the high versus low bilirubin group (P bilirubin levels of liver recipients before live donor transplantation is associated with decreased postoperative IRI.

    The learning curve for performing living donor hemiliver procurement (LDHP) via small upper midline incision (UMI) has not been determined. Living donors (n=101) who underwent LDHP via UMI were included to investigate the learning curve using cumulative sum analysis. The cumulative sum analysis showed that nine cases for right lobe (case #23) and 19 cases for left lobe (case #32 in the whole series) are needed for stable and acceptable surgical outcomes in LDHP via UMI. The established phase (n=69, since case #33) had a significantly shorter operative time, a smaller incision size, and less blood loss than the previous learning phase (n=32, serial case number up to the last 19th left lobe case). Multivariate analysis showed that the learning phase, high body mass index ≥25 kg/m(2) , and left lobe graft procurement are the factors associated with surgical events including operative blood loss ≥400 mL, operative time ≥300 minutes, or surgical complications ≥Clavien-Dindo grade II. There is an obvious learning curve in performing LDHP via UMI, and 32 cases including both 19 cases for left lobe and nine cases for right lobe are needed for having stable and acceptable surgical outcomes.

    Aim The aim of this study was to describe our results and investigate the survival of below-18-year-old patients undergoing LRDLT and the factors affecting this. Background Living Related Donor Liver Transplantation (LRDLT) has become a good option to provide suitable grafts for children with liver diseases. Using this method, children who have no chance for life can live a much longer life. Patients and methods The present study is a historical cohort study carried on 191 patients below-18-year-sold who had undergone LRDLT for the first time in the Namazi hospital liver transplantation center. Survival rate of the patients was assessed using Kaplan-Meier method. The effect of factors related to the recipients, donors, and the transplantation process on the patients’ survival was also investigated. Results 1, 3, 5 and 11-year survival of patients was 71%, 66%, 65%, and 65%, respectively. In the univariate analysis, age, weight at transplantation, PELD/MELD score, existence of post-transplant complications were found to be effective factors on the patients’ survival. In the multivariate analysis, weight at transplantation, PELD/MELD score, and existence of post-transplant complications were the prognostic variables. Conclusion LRDLT is now well established with satisfactory results in our center. Although the survival rate of the patients is lower than the survival rate reported in other studies, but the survival of the patients who had survived 1 month after the transplantation was comparable to other studies.

    Low birth weight is linked to hypertension, chronic kidney disease and even end stage renal disease. We hypothesized that living kidney donors born with lower birth weight may be at increased risk of hypertension, albuminuria or reduced GFR beyond what is typical following uninephrectomy. 257 living kidney donors who donated at the University of Minnesota between 1967 and 2005 underwent iohexol GFR and urinary albumin excretion measurements. Predictors of iohexol GFR <60 ml/min/1.73m2, albuminuria and hypertension were examined using logistic regression. Predictors examined include age at GFR measurement, time since donation, BMI, gender, serum creatinine level (at donation and GFR measurement), systolic and diastolic blood pressure, race, and birth weight. The latter was obtained through self-report and verified through birth certificates and family members. Older age, higher BMI, and time from donation were associated with reduced GFR. Older age and higher BMI were also associated with hypertension. Birth weight was not associated with GFR <60 ml/min/1.73m2: OR=0.70, 95% CI (0.28, 1.74, p=0.45) or hypertension: OR=0.92, 95% CI (0.46, 1.84), p=0.82 but was associated with albuminuria: OR=0.37, 95% CI (0.15, 0.92), p=0.03. This data further strengthens the link between low birth weight and potential adverse renal outcomes. PMID:24547690

    Hyperkalemia is an electrolyte disorder that may occur during the first few months after a renal transplant, in patients undergoing cyclosporine immunosuppression. We present our experience with cyclosporine-associated hyperkalemia in living-donor renal transplant recipients, with isolated clinically relevant hyperkalemia soon after surgery. We report 4 living-donor renal recipients with hyperkalemia soon after transplant. Severe unexpected hyperkalemia (7.5- 9.4 mmol/L) was noted in our patients 12, 20, 22, and 34 days after transplant. The C2 cyclosporine concentration was within recommended range or slightly greater than 1200 ng/mL. The hypertonic glucose/insulin treatment along with potassium diet was without results. A reduction in daily cyclosporine dosages, along with 1- to 2-week administration of fludrocortisone was effective. The patients became normokalemic taking a standard, triple-drug immunosuppression protocol, and were discharged home with normal renal function. There were no repeat episodes of hyperkalemia in any of the patients during 12 months of follow-up. Cyclosporine should be considered a cause of hyperkalemia in renal transplant recipients. Successful treatment with fludrocortisone confirms that transitional pseudohypoaldosteronism has a potential nephrotoxic effect of cyclosporine. We recommend close monitoring of the cyclosporine concentration and administering fludrocortisone when treating hyperkalemia in renal transplant recipients.

    Hemodynamic monitoring is vital during liver transplant surgeries because distinct hemodynamic changes are expected. The continuous noninvasive arterial pressure (CNAP) monitor is a noninvasive device for continuous arterial pressure measurement by a tonometric method. This study compared continuous noninvasive arterial pressure monitoring with invasive direct arterial pressure monitoring in living-liver donors during transplant. There were 40 patients analyzed while undergoing hepatic lobectomy for liver transplant. Invasive pressure monitoring was established at the radial artery and continuous noninvasive arterial pressure monitoring using a finger sensor was recorded simultaneously from the contralateral arm. Systolic, diastolic, and mean arterial pressures from the 2 methods were compared. Correlation between the 2 methods was calculated. A total of 5433 simultaneous measurements were obtained. For systolic arterial blood pressure, 55% continuous noninvasive arterial pressure measurements were within 10% direct arterial measurement; the correlation was 0.479, continuous noninvasive arterial pressure bias was -0.3 mm Hg, and limits of agreement were 32.0 mm Hg. For diastolic arterial blood pressure, 50% continuous noninvasive arterial pressure measurements were within 10% direct arterial measurement; the correlation was 0.630, continuous noninvasive arterial pressure bias was -0.4 mm Hg, and limits of agreement were 21.1 mm Hg. For mean arterial blood pressure, 60% continuous noninvasive arterial pressure measurements were within 10% direct arterial measurement; the correlation was 0.692, continuous noninvasive arterial pressure bias was +0.4 mm Hg, and limits of agreement were 20.8 mm Hg. The 2 monitoring techniques did not show acceptable agreement. Our results suggest that continuous noninvasive arterial pressure monitoring is not equivalent to invasive arterial pressure monitoring in donors during living-donor liver transplant.

    Living donation is the best choice for kidney transplantation, obtaining long-lasting good results for the recipient. Some concern still remains regarding the donor's long-term health. Kidney biopsy was routinely performed in our donor population at the time of donation many years ago. We found the existence of morphological kidney disease in those samples, in spite of normal clinical evaluations before donation. We attempted to correlate those abnormalities with long-term clinical outcomes. Donors were at least 10 years after surgery. A medical interview, including the SF-36 Health Survey, laboratory evaluation, and ambulatory blood pressure monitoring was performed on 27 donors meeting the inclusion criteria. Two donors had died after donation from unrelated causes with no known nephropathy. Histological analysis showed abnormalities in 16 of 29 donors. We found an increased prevalence of hypertension compared to the general population. Interestingly, there was no proteinuria in the donor population, and none developed clinical nephropathy. All subjects felt emotionally rewarded with donation, stating that their lives had no limitations. Our results suggest that kidney biopsy is neither necessary nor useful prior to donation because, although many donors had morphological kidney disease, none developed clinical nephropathy in the long term.

    The state of organ transplantation in general in China is experiencing transition; however, living-donor organ transplantation has gained more attention recently. We have found that because traditional Chinese ideas, few Chinese transplantation surgeons have the quality of life (QOL) and mental health of living transplantation donors and recipients as their focus in care giving. Physicians outside of China typically have a different view. This study investigated QOL and psychology characteristics in Chinese living-related kidney donors and recipients after transplantation. Demographics, socioeconomics, transplantation processes, QOL scores, and psychosocial outcomes of 169 pairs of living-related kidney donors and recipients were analyzed using a self-made socio-demographic questionnaire, the short-form 36 health survey, and the Zung self-rating anxiety and depression scales. The majority of both donors (81.8%, 90/110) and recipients (83.1%, 103/124) were at secondary school or lesser education levels. Eighty-five and five tenths percent (94/110) of donors and 54.8% (68/124) of recipients were of moderate or low incomes. In addition, the donors were predominantly female (61.8%, 68/110), 6 of whom (5.5%, 6/110) stated that their transplantation had a negative impact on marriage due to kidney donation. The evaluation of the donors' QOL was not significantly different from that of the Chinese norm. The recipients' QOL was obviously improved comparing with the hemodialysis patients. There was no anxiety and depression among donors, but slightly anxious (1.6%, 2/124) and depressive (5.6%, 7/124) symptoms were found among recipients. Living-related kidney transplantation did not adversely affect the lives and psychological aspects of donors and significantly improved the QOL of recipients. Screening donors strictly, perfecting the medical care system, intensifying follow-up and social supports, and providing necessary healthy and psychological counseling should be

    Desensitisation is a procedure undergone by the recipient of a kidney transplant from a donor who is cross-match positive. The aim of this study was to present the outcomes from our hospital of kidney transplant recipients from HLA-incompatible live donors after desensitisation. We studied 32 patients aged 46±14 years with a mean fluorescence intensity (MFI) versus class I HLA of 7979±4089 and 6825±4182 MFI versus class II and relative intensity scale (RIS) of 8.9±7.6. The complement-dependent cytotoxicity (CDC) cross-matching test was positive in 18 patients, flow cytometry was positive in 7 patients and donor-specific antibodies (DEA) were detected in 7. The protocol used was rituximab, plasmapheresis/immunoadsorption, immunoglobulins, tacrolimus, mycophenolic acid derivatives and prednisone. After 8±3 sessions of plasmapheresis/immunoadsorption, 23 patients were trasplanted (71.9%) and desensitisation was ineffective in 9. There were baseline differences in MFI class I (P<.001), RIS (P=.008), and CDC cross-matching, DSA and flow cytometry (P=.05). MFI class I and RIS were predictors of inefficiency in ROC curves. After follow-up of 43±30 months, 13 patients (56%) presented postoperative bleeding, 3 (13%) delayed graft function, 4 (17.4%) acute rejection, 6 (26%) CMV viraemia and 1 (4%) BK viraemia. Five-year patient survival was 90%, with 86% allograft survival. Five-year creatinine was 1.5±0.4 and proteinuria was 0.5±0.7. Kidney transplantation from HLA-incompatible live donors after desensitisation was possible in 71.9% of patients. MFI class I and RIS predict the inefficiency of desensitisation. Five-year allograft survival (86%) was acceptable with a low incidence of acute rejection (17.4%), although with a greater trend towards postoperative bleeding.

    Background: Most current knowledge on kidney concentrations of nephrotoxic metals like cadmium (Cd), mercury (Hg), or lead (Pb) comes from autopsy studies. Assessment of metal concentrations in kidney biopsies from living subjects can be combined with information about exposure sources like smoking, diet, and occupation supplied by the biopsied subjects themselves. Objectives: To determine kidney concentrations of Cd, Hg, and Pb in living kidney donors, and assess associations with common exposure sources and background factors. Methods: Metal concentrations were determined in 109 living kidney donors aged 24-70 years (median 51), using inductively coupled plasma-mass spectrometry (Cd and Pb) and cold vapor atomic fluorescence spectrometry (Hg). Smoking habits, occupation, dental amalgam, fish consumption, and iron stores were evaluated. Results: The median kidney concentrations were 12.9 {mu}g/g (wet weight) for cadmium, 0.21 {mu}g/g for mercury, and 0.08 {mu}g/g for lead. Kidney Cd increased by 3.9 {mu}g/g for a 10 year increase in age, and by 3.7 {mu}g/g for an extra 10 pack-years of smoking. Levels in non-smokers were similar to those found in the 1970s. Low iron stores (low serum ferritin) in women increased kidney Cd by 4.5 {mu}g/g. Kidney Hg increased by 6% for every additional amalgam surface, but was not associated with fish consumption. Lead was unaffected by the background factors surveyed. Conclusions: In Sweden, kidney Cd levels have decreased due to less smoking, while the impact of diet seems unchanged. Dental amalgam is the main determinant of kidney Hg. Kidney Pb levels are very low due to decreased exposure.

  6. Normal liver stiffness: a study in living donors with normalliver histology

    2015-01-01

    AIM To define the normal range of liver stiffness (LS)values using transient elastography in living-relatedliver transplantation candidate donors with normal liverhistology.METHODS: LS was measured using Fibroscan in 50 (16women, 34 men) healthy potential donors (mean age28.4 ± 5.9 years) who were being evaluated for liverdonation for their relatives at the National Liver Institute,Menoufeya University, Egypt. All potential donors hadnormal liver tests and were negative for hepatitis Bor C virus infection. Abdominal ultrasounds showednormal findings. None of the subjects had diabetes,hypertension, renal impairment, heart disease, or bodymass index 〉 30 kg/m2. All subjects had normal liverhistology upon liver biopsy. They all donated the rightlobe of their liver with successful outcomes.RESULTS: The mean LS was 4.3 ± 1.2 kPa (range:1.8-7.1 kPa). The 5th and 95th percentiles of normal LSwere 2.6 kPa and 6.8 kPa, respectively, with a medianof 4 kPa; the interquartile range was 0.6 ± 0.4. LSmeasurements were not significantly different betweenmen and women (4.4 ± 1.1 kPa vs 3.9 ± 1.3 kPa) anddid not correlate with age. However, stiffness valueswere significantly lower in subjects with a body massindex 〈 26 kg/m2 compared to those with an index ≥ 26kg/m2 (4.0 ± 1.1 kPa vs 4.6 ± 1.2 kPa; P 〈0.05). Therewere no differences in hospital stay or postoperativebilirubin, albumin,alanine and aspartate transaminases,or creatinine levels (at discharge) between donors withlivers stiffness ≤ 4 kPa and those with stiffness 〉 4 kPa.CONCLUSION: Healthy donors with normal liverhistology have a median LS of 4 kPa. Stiffness valuesare elevated relative to increase in body mass index.

    Full Text Available OBJECTIVE To verify if the type of donor is a risk factor for infection in kidney transplant recipients. METHODS Systematic Review of Literature with Meta-analysis with searches conducted in the databases MEDLINE, LILACS, Embase, Cochrane, Web of Science, SciELO and CINAHL. RESULTS We selected 198 studies and included four observational studies describing infections among patients distinguishing the type of donor. Through meta-analysis, it was shown that in patients undergoing deceased donor transplant, the outcome infection was 2.65 higher, than those who received an organ from a living donor. CONCLUSION The study showed that deceased kidney donor recipients are at an increased risk for developing infections and so the need for establishing and enforcing protocols from proper management of ischemic time to the prevention and control of infection in this population emerges.

  9. Trading with the waiting-list: the justice of living donor list exchange.

    2010-05-01

    In a Living Donor List Exchange program, the donor makes his kidney available for allocation to patients on the postmortal waiting-list and receives in exchange a postmortal kidney, usually an O-kidney, to be given to the recipient he favours. The program can be a solution for a candidate donor who is unable to donate directly or to participate in a paired kidney exchange because of blood group incompatibility or a positive cross-match. Each donation within an LDLE program makes an additional organ available for transplantation. But because most of the pairs making use of the program will be A/O incompatible, it will also tend to increase the waiting time for patients with blood group O, who already have the longest waiting time. It has therefore been objected that the program is materially unjust, because it further disadvantages the least advantaged. This objection appeals to John Rawls' difference principle. However, the context for which Rawls proposed that difference principle, is significantly different from the present one. Applying the principle here amounts to a lop-sided trade-off between considerations of need and considerations of overall utility. Considerations of formal justice, however, may lead to a stronger objection to LDLE programs. Such a program means that one O-patient on the waiting list is exempted from the application of the general criteria used in constructing the list because he has a special bargaining advantage. This objection is spelled out and weighed against the obvious attraction of LDLE in a situation of (extreme) organ scarcity.

    This research examines perceptions concerning living (n = 1,253) and nonliving (n = 1,259) organ donation among Hispanic adults, a group considerably less likely than the general population to become donors. Measures are derived from the Theory of Planned Behavior (Ajzen, 1991) and Vested Interest Theory (Crano, 1983, 1997). A substantial percentage of respondents reported positive attitudes and high personal stake concerning organ donation. Mean differences in norms, attitudes, intentions, and assumed immediacy of payoff were found between living and nonliving donor groups, suggesting that these two donation formats are dissimilar and should be examined independently. Accordingly, separate hierarchical multiple regression models were estimated for living and nonliving donation. Analyses supported both theoretical frameworks: Constructs associated with Planned Behavior and Vested Interest independently contributed to donor intentions. The implications of these results, and our recommendations for future health campaigns, are presented in light of these theoretical models.

    Full Text Available Background: Kidney transplantation is the preferred treatment option for end stage kidney disease. Live kidney donation is an established form of organ donation; but it carries the risk of an unnecessary surgery in a normal individual. These donors remain at an increased risk of multiple medical problems for the rest of their life. Objective: In this study, we evaluated the immediate impact of uninephrectomy among kidney donors during the period of post-transplant hospital stay. Materials and Methods: This cross-sectional study was done at BIRDEM General Hospital from January 2006 to June 2014. All kidney donors who had undergone graft nephrectomy during the study period were the study population. All the donors underwent Tc-99m diethylene triamine pentaacetic acid (Tc-99m DTPA renogram for measurement of glomerular filtration rate (GFR. GFR was also estimated by different equations in both pre-transplant and post-transplant periods. Pre-uninephrectomy GFR and post-uninephrectomy GFR of donors were compared. Results: Total number of subjects was 81, male 48 and female 33. Mean age was 36.3 ± 9.9 years. Mean postoperative hospital stay was 8.2 ± 2.0 days. The mean pre-operative measured glomerular filtration rate (mGFRDTPA was 99.54 ± 19.06 mL/min/1.73 m2 and mean estimated glomerular filtration rate (eGFRCKD-EPI was 99.0 ± 18.55 mL/min/1.73 m2 (p=0.855. In post-nephrectomy period mean urine output decreased from 2708.1 ± 842.8 to 2228.4 ± 702.4 mL/day (p=0.000. Mean SBP lowered from 120.3 ± 12.5 to 115.6 ± 9.2 mm of Hg (p=0.000 after nephrectomy. There was significant increase in blood urea (from 19.7 ± 5.7 to 30.4 ± 9.5 mg/dL, p=0.000 and serum creatinine (from 0.90 ± 0.16 to 1.26 ± 0.24 mg/dL, p=0.000 in post-uninephrectomy period. Mean mGFRDTPA of the subjects of non-nephrectomized kidney of the donors was 49.18 ± 9.50 mL/min/1.73 m2 and mean eGFRCKD-EPI of same kidneys was 69.09 ± 16.79 mL/min/1.73m2 (p=0.000 after uni

    BACKGROUND:Living donor liver transplantation (LDLT) has been increasingly used to treat hepatic tumors worldwide in recent years, and is currently the most effective alternative to deceased donor liver transplantation to overcome the problem of organ shortage. LDLT has played an enormous role in treating early malignant hepatic tumors. But the indication of LDLT for malignant hepatic tumors is based on indeifnite criteria. This review summarizes the recent studies in LDLT for treating malignant hepatic tumors. DATA SOURCES:A literature research of the PubMed database was conducted and research articles were reviewed. RESULTS:The current data on LDLT for malignant hepatic tumors, combined with our hospital experience, indicated that if a patient with hepatocellular carcinoma (HCC) who meets with the conventional Milan criteria cannot undergo tumor resection because of poorly preserved liver function, and a cadaveric graft is dififcult to obtain within six months, LDLT may be selected. In a patient with recurrence of HCC after conventional therapies, feasibility, optimal timing, and efifcacy of LDLT as a second-line treatment should be determined. CONCLUSIONS:Tumor recurrence is related to the biological behavior and staging of the tumor. New immunosuppressors which have anti-tumor effects and inhibit the immune system need to be developed. The indications of LDLT for hepatic malignant tumors should be selected meticulously.

    Our objective was to evaluate our overall experience in pediatric renal transplantation. Between March 1976 and March 2004, 1,600 live-donor kidney transplantations were carried out in our center; 216 of the patients were 18 years old or younger (mean age 12.9 years). There were 136 male patients and 80 female patients. The commonest causes of end-stage renal disease (ESRD) were renal dysplasia (22%), nephrotic syndrome (20%), hereditary nephritis (16%), and obstructive uropathy (16%). Of the donors, 94% were one-haplotype matched and the rest were identical. Pre-emptive transplantation was performed in 51 (23%) patients. Triple-therapy immunosuppression (prednisone + cyclosporine + azathioprine) was used in 78.2% of transplants. Rejection-free recipients constituted 47.7%. Hypertension (62%) was the commonest complication. A substantial proportion of patients (48%) were short, with height standard deviation score (SDS) less than -1.88. The overall infection rate was high, and the majority (53%) of infections were bacterial. The graft survival at 1 year, 5 years and 10 years were 93.4%, 73.3% and 48.2%, respectively, while the patients' survival at 1, 5 and 10 years were 97.6%, 87.8% and 75.3%, respectively. Despite long-term success results of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.

    Living-donor liver transplantation (LDLT) has been accepted as feasible treatment for fulminant hepatic failure (FHF), although it has generated several debatable issues. In this study, we investigated the prognostic factors predicting fatal outcome after LDLT for FHF. From April 1999 to April 2011, 60 patients underwent LT for acute liver failure, including 42 patients for FHF at Samsung Medical Center, Seoul, Korea. Among 42 patients, 30 patients underwent LDLT for FHF, and the database of these patients was analyzed retrospectively to investigate the prognostic factors after LDLT for FHF. Among 30 patients, 7 patients (23%) died during the in-hospital period within 6 months, and 23 patients (77%) survived until recently. In univariate analyses, donor age (>35 years), graft volume (GV)/standard liver volume (SLV) (120 minutes), hepatic encephalopathy (grade IV), hepato-renal syndrome (HRS), and history of ventilator care were associated with fatal outcome after LDLT for FHF. In multivariate analyses, HRS, GV/SLV (35 years) were significantly associated with fatal outcome. Although the statistical significance was not shown in this analysis (P = .059), hepatic encephalopathy grade IV also appears to be a risk factor predicting fatal outcome. The survival of patients with FHF undergoing LDLT was comparable to that in published data. In this study, HRS, GV/SLV 35 years are the independent poor prognostic factors.

    Living donor liver transplant(LDLT)is a major surgi-cal undertaking.Detailed pre-operative assessment of the vascular and biliary anatomy is crucial for safe and successful harvesting of the graft and transplantation.Computed tomography(CT)and magnetic resonance imaging(MRI)are currently the imaging modalities of choice in pre-operative evaluation.These cross-sec-tional imaging techniques can reveal the vascular and biliary anatomy,assess the hepatic parenchyma and perform volumetric analysis.Knowledge of the broad indications and contraindications to qualify as a recipi-ent for LDLT is essential for the radiologist reporting scans in a pre-transplant patient.Similarly,awareness of the various anatomical variations and pathological states in the donor is essential for the radiologist to generate a meaningful report of his/her observations.CT and MRI have largely replaced invasive techniques such as catheter angiography,percutaneous cholan-giography and endoscopic retrograde cholangiopan-creatography.In order to generate a meaningful report based on these pre-operative imaging scans,it is also mandatory for the radiologist to be aware of the sur-geon’s perspective.We intend to provide a brief over-view of the common surgical concepts of LDLT and give a detailed description of the minimum that a radiologist is expected to seek and report in CT and MR scans per-formed for LDLT related evaluation.

    The Israeli transplantation law of 2008 stipulated that organ trading is a criminal offense, and banned the reimbursement of such transplants by insurance companies, thus decreasing dramatically transplant tourism from Israel. We evaluated the law's impact on the number and the socio-demographic features of 575 consecutive living donors, transplanted in the largest Israeli transplantation center, spanning 5 years prior to 5 years after the law's implementation. Living kidney donations increased from 3.5 ± 1.5 donations per month in the pre-law period to 6.1 ± 2.4 per month post-law (p trading in accordance with Istanbul Declaration, was associated with an increase in local transplantation activity, mainly from related living kidney donors, and a change in the profile of unrelated donors into an older, higher educated, white collar population.

    This study describes the surgical technique and outcomes of live donor renal allografts with multiple arteries in which the lower polar artery was anastomosed to the inferior epigastric artery after declamping. Between 1988 and 2004, 477 consecutive live donor renal transplants were performed, including 429 with single and 48 with multiple arteries. Anastomosis of the lower polar artery to the inferior epigastric artery was used for 15 grafts with multiple arteries. Successful revascularization of all areas of the transplanted graft was confirmed by Doppler ultrasonography in most patients and radionuclide renal scanning +/- MRA in some patients. In live donor renal transplantation with multiple arteries, the anastomosis of the lower polar artery to the inferior epigastric artery after declamping avoids prolongation of the ischemia time that occurs with other surgical and microsurgical techniques of intracorporeal and ex vivo surgeries.

    Full Text Available It is well known that the presence of end-stage liver disease increases the risk of developing hepatocellular carcinoma (HCC. Liver transplantation (LT for patients within the Milan criteria has become a standard treatment for HCC in most developed centers worldwide. However, a major cause of death in cirrhotic patients with HCC after transplantation is tumor recurrence, including peritoneal recurrences, which develops rarely but presents a significant problem with regard to their management. Our experience includes two cases with HCC within the Milan criteria of peritoneal recurrences after living donor LT. Both patients had interventions for HCC in their medical history before LT, and we propose that these might have been a possible cause of the HCC peritoneal recurrence.

    BK polyomavirus (BKPyV) commonly reactivates after kidney transplantation, and can cause polyomavirus-associated nephropathy (PyVAN), whereas after allogeneic stem cell transplantation the most frequent manifestation of BKPyV is polyomavirus-associated hemorrhagic cystitis (PyVHC). Despite high-level BKPyV replication in both, the pathogenesis and manifestation of both BKPyV entities appears to differ substantially. We describe an unusual case of simultaneous PyVAN and PyVHC presenting with acute symptoms in a BKPyV-IgG positive recipient eight months after kidney transplantation from a haploidentical living donor, who was BKPyV-IgG negative. Symptoms of cystitis and viremia subsided rapidly after reduction of immunosuppression.

    BACKGROUND: Hepatic artery (HA) reconstruction is one of the key steps for living donor liver transplantation (LDLT). The incidence of HA thrombosis has been reduced by the introduction of microsurgical techniques under a high resolution microscope or loupe. METHODS: We report our experience in 101 cases of HA reconstruction in LDLTs using the graft-artery-unclamp and posterior-wall-ifrst technique. The reconstructions were completed by either a plastic surgeon or a transplant surgeon. RESULTS: The rate of HA thrombosis was 2%(2/101). The risk factors for failed procedures appeared to be reduced by participation of the transplant surgeon compared with the plastic surgeon. For a graft with duplicate arteries, we considered no branches should be discarded even with a positive clamping test. CONCLUSIONS: HA reconstruction without clamping the graft artery is a feasible and simpliifed technique, which can be mastered by transplant surgeons with considerable microsurgical training.

    Stent placement has become common practice for bronchial stenosis (BS) after lung transplantation (LT). Especially, segmental BS after lobar LT requires a complex stenting technique. We describe a case of multiple segmental bronchial stenoses treated by the kissing-stents technique using balloon-expandable metallic stents after living-donor lobar LT. Based on the vascular kissing-stents technique, we simultaneously placed two stents, side by side, in the superior segmental bronchus and the basal segmental bronchus of the right transplanted lobar lung. This technique may represent a valuable option for complex segmental BS after lobar LT. © The Author 2014.

    The evaluation of the measured Glomerular Filtration Rate (mGFR) or estimated Glomerular Filtration Rate (eGFR) is key in the proper assessment of the renal function of potential kidney donors. We aim to study the correlation between glomerular filtration rate estimation equations and the measured methods for determining renal function. We analysed the relationship between baseline GFR values measured by Tc-(99)m-DTPA (diethylene-triamine-pentaacetate) and those estimated by the four-variable Modification of Diet in Renal Disease (MDRD4) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in a series of living donors at our institution. We included 64 donors (70.6% females; mean age 48.3±11 years). Baseline creatinine was 0.8±0.1 mg/dl and it was 1.1±0.2 mg/dl one year after donation. The equations underestimated GFR when measured by Tc(99)m-DTPA (MDRD4-9.4 ± 25ml/min, P<.05, and CKD-EPI-4.4 ± 21ml/min). The correlation between estimation equations and the measured method was superior for CKD-EPI (r=.41; P<.004) than for MDRD4 (r=.27; P<.05). eGFR decreased to 59.6±11 (MDRD4) and 66.2±14ml/min (CKD-EPI) one year after donation. This means a mean eGFR reduction of 28.2±16.7 ml/min (MDRD4) and 27.31±14.4 ml/min (CKD-EPI) at one year. In our experience, CKD-EPI is the equation that better correlates with mGFR-Tc(99)m-DTPA when assessing renal function for donor screening purposes. Copyright © 2017 Sociedad Española de Nefrología.

    We quantified the rates of hepatic regeneration and functional recovery for 6 months after right hepatic lobectomy in living donors for liver transplantation. Twelve donors were studied pre-donation (baseline); 8 were retested at a mean ± SD of 11±3 days after donation (T1), 10 were retested at a mean of 91±9 days after donation (T2), and 10 were retested at a mean of 185±17 days after donation (T3). Liver and spleen volumes were measured with computed tomography (CT) and single-photon emission computed tomography (SPECT). Hepatic metabolism was assessed with caffeine and erythromycin, and hepatic blood flow (HBF) was assessed with cholates, galactose, and the perfused hepatic mass (PHM) by SPECT. The regeneration rates (mL kg(-1) of body weight day(-1)) by CT were 0.60±0.22 mL from the baseline to T1, 0.05±0.02 mL from T1 to T2, and 0.01±0.01 from T2 to T3; by SPECT they were 0.54±0.20, 0.04±0.01, and 0.01±0.02, respectively. At T3, the liver volumes were 84%±7% of the baseline according to CT and 92%±13% of the baseline according to SPECT. Changes in the hepatic metabolism did not achieve statistical significance. At T1, the unadjusted clearance ratios with respect to the baseline were 0.75±0.07 for intravenous cholate (Pliver were up to 50% greater than the baseline values, suggesting recruitment of HBF by the regenerating liver. Increased cholate shunt, increased spleen volume, and decreased platelet count, were consistent with an altered portal circulation. In conclusion, initial hepatic regeneration is rapid, accounts for nearly two-thirds of total regeneration, and is associated with increases in HBF and cholate uptake. Right lobe donation alters the portal circulation of living donors, but the long-term clinical consequences, if there are any, are unknown.

    MSUD occurs due to deficiency of enzyme BCKAD required for metabolism of leucine, isoleucine, and valine leading to the accumulation of these and their ketoacids causing acute metabolic decompensation manifesting as encephalopathy or sudden death. The patient requires special protein-restricted diet to survive. As this enzyme is expressed in liver, liver transplantation has been successfully performed as a cure. We report two patients of MSUD who underwent LDLT while their livers were used as a domino graft for other biliary cirrhotic patients. A 22-month-old male child diagnosed as a case of classic MSUD underwent LDLT from an altruistic aunt as donor following which his serum leucine levels normalized on an unrestricted protein diet. His liver was used as a domino graft. A 38-month-old female child with diagnosed MSUD underwent LDLT from a swap donor, and her liver was used as a domino graft. Her DQ improved post-transplant. LDLT from non-heterozygous donors is a cure for classical MSUD. Their livers can be used as domino grafts for non-MSUD cases. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Socioeconomic deprivation is associated with higher renal replacement therapy acceptance rates in the UK but lower rates of living kidney transplantation. This study examines donor-recipient relationship patterns with socioeconomic deprivation in the white population of England. Demographic characteristics of all white live renal transplant donors and recipients between 2001 and 2010 in England were analyzed. Patterns of donor-recipient relationship were analyzed to see whether they differed according to an ecological measure of socioeconomic status (Index of Multiple Deprivation). Group comparisons were performed using chi-square tests and multivariable logistic regression. Sources of living kidney transplants differed with deprivation (p relative" donor and less likely from spouses/partners. Logistic regression suggested differences seen with spouse/partner donations with deprivation were explained by differences in the age and gender of the recipients. The source of living kidneys differs by level of area deprivation. Given the disparity in rates of living kidney transplants between the most and least socioeconomically deprived, there is a need to understand the reasons behind these observed relationship differences, with the aim of increasing transplantation rates in the most deprived. © 2013 John Wiley & Sons A/S.

    In adult-to-adult living liver transplantation, small-for-size graft syndrome sometimes occurs. The relationship between the hemodynamic changes and histologic findings has not been studied in patients with failure of small-for-size grafts. We analyzed the relationship between the postoperative hemodynamic changes and pathologic findings in patients with small-for-size grafts that ended in graft failure. From March 1999 to December 2002, adult-to-adult living-donor liver transplantation with small-size grafts (graft volume/standard liver volume less than 40%) was performed in eight patients. Three patients died from graft failure caused by overperfusion, which was diagnosed from pathologic findings. We analyzed the relation between hepatic hemodynamic parameters, such as portal venous blood velocity or splenic arterial pulsatility index, and histologic changes in patients with graft failure. Severe portal hyperperfusion (90 cm/sec at the umbilical portion) was observed on postoperative day 1. Among patients with graft failure, critical hemodynamic changes, such as sudden onset of extremely deteriorated portal venous blood flow, occurred during the early postoperative period (postoperative day 5, 3, 6, respectively). Histologic examination revealed vacuolar changes in the cytoplasm of hepatocytes, and submassive necrosis indicated intrasinusoidal pressure elevation. These changes were not observed in the biopsy obtained soon after reperfusion. In conclusion, critically decreased vascular beds may cause intrasinusoidal pressure elevation and sinusoidal circulatory disturbances.

    Full Text Available Objective:To conduct an epidemiological analysis on the main microbiological markers in bone tissue that was processed at the musculoskeletal tissue bank of Hospital São Vicente de Paulo, in Passo Fundo, between August 2007 and October 2011.Methods:Between August 2007 and October 2011, 202 musculoskeletal tissue samples were collected for the tissue bank. Among these, 159 samples were from living donor patients and 43 were from cadaver donors. The following serological tests were requested: hepatitis B, hepatitis C, syphilis, cytomegalovirus, Chagas disease, toxoplasmosis, HIV and HTLV.Results:Among the 159 living donors, 103 (64.75% were men and 56 (35.25% were women. The patients' mean age was 59.35 ± 8.87 years. Out of this total, 76 tissue samples (47.8% from donors were rejected. There was no difference in the number of rejections in relation to sex (p = 0.135 or age (p = 0.523. The main cause of rejection was serologically positive findings for the hepatitis B virus, which was responsible for 48 rejections (63.15%. Among the 43 cadaver donors, the mean age was 37.84 ± 10.32 years. Of these, 27 (62.8% were men and 16 (37.2% were women. Six of the samples collected from cadaver donors were rejected (13.9%, and the main cause of rejection was serologically positive findings for the hepatitis C virus, which was responsible for three cases (50%. There was no significant difference in the number of rejections in relation to sex (p = 0.21 or age (p = 0.252.Conclusion:There were a greater number of rejections of tissues from living donors (47.8% than from cadaver donors (13.9%. Among the living donors, the main cause of rejection was the presence of serologically positive findings of the hepatitis B virus, while among the cadaver donors, it was due to the hepatitis C virus.

    Hepatic hemodynamic changes in grafts after living donor liver transplantation (LDLT) are complicated. In this study, computed tomography (CT) perfusion parameter values, especially portal vein perfusion (PVP), was retrospectively analyzed in recipients both with and without small-for-size syndrome (SFSS). PVP was significantly higher in non-SFSS recipients on post-operative day (POD) 14 or 28 than in normal donors before donation (p spleen size ratio and PVP on POD 14 in non-SFSS group (r = -0.545, p = 0.002). Furthermore, PVP in the SFSS group was significantly greater than in the non-SFSS group on POD 14 (p = 0.042). In conclusion, we successfully evaluated normal hemodynamic changes in grafts without SFSS by CT perfusion examination. To our knowledge, this is the first study on hemodynamic changes of living donor liver grafts using CT technique.

    Living donor liver transplantation (LDLT) is an alternative to conventional transplantation given its excellent results. The aim of this study is to evaluate long-term outcomes in LDLT recipients. 100 consecutive THDV recipients from the Hospital Clínic of Barcelona from March 2000 to October 2015 were included. The main indication for transplantation was end-stage liver disease (58%) followed by hepatocellular carcinoma (41%). 95% of grafts consisted of the right liver of the donor and the 5% of the left liver. After a median follow-up of 65.5 months, patient and graft survival at 1, 3, and 5 years was 93%, 80% and 74% and 90%, 76%, and 71%, respectively. The overall re-transplant rate was 9%. The most common long-term complication was biliary stenosis (40%) with an average time of onset of 13.5±12 months, with repeated admissions and an average of 1.9±2 endoscopic procedures and 3.5±3 Radiological procedures per patient. The definitive treatment was radiological dilation in 40% of cases, surgical intervention in 22.5% and re-transplantation in 7.5%. Given the long-term results, LDLT is confirmed as an alternative to conventional transplantation. However, the high rate of late biliary complications involves repeated admissions and invasive treatments that, while not compromising survival, can affect the patient's quality of life.

    Liver transplant is a definite treatment of decompensated liver disease. Because of the shortage of livers from deceased donors, living-donor liver transplant is becoming more common. Here, we analyzed our clinical experience in the follow-up care of these patients. Liver transplant recipients seen at the Sindh Institute of Urology and Transplantation (Karachi, Pakistan) were included in this analysis. Baseline characteristics and follow-up events were recorded. Our study population included 76 liver transplant patients registered at our clinic. Median age was 42 years, with 62 patients (81.6%) being males. The most common indication of transplant was hepatitis C virus-related cirrhosis (42 patients; 55%), followed by hepatitis B-hepatitis D virus coinfection (8 patients; 10.5%). Anastomotic biliary stricture developed in 16 patients (21.1%),which required biliary stenting. Biliary leak developed in 5 patients (6.6%), and renal cell carcinoma developed in 1 patient. Two recipients died due to hepatitis C virus-related fibrosing cholestasis hepatitis and pulmonary com plications. Posttransplant diabetes mellitus developed in 36 (47.1%), hypertension in 17 (38.6%), and dyslipidemia in 19 patients (25%). Of 42 patients with hepatitis C virus infection, 26 were treated with pegylated interferon and ribavirin, of which 65.3% achieved sustained virologic response at 24 weeks. The other 16 patients received sofosbuvir com - bined with ribavirin for 24 weeks. A sustained virologic response at 12 weeks was achieved in 5 patients, with not yet determined results in the remaining patients. Seven patients were lost to follow-up. Hepatitis C-related cirrhosis was the most common indication for liver transplant, and infection recurrence was observed in our patients. Biliary anastomotic stricture formation was the most prevalent complication after transplant. As liver transplants are becoming more widely available for Pakistani patients at home and abroad, gastroenterologists and

    Renal transplantation that offers a good quality of life still is not performed by the majority of countries of black Africa. We started a pilot project of renal transplantation in Ivory Coast 2 years ago. The present paper reports the preliminary results, difficulties related to the program, and perspectives regarding its expansion. Ten living related kidney transplantations have been performed over a 2-year period. Recipients and their respective donors were male. The mean age of the recipients was 42.8 years (22-57), and the mean age of the donors was 29.4 years (22-43). The mean number of mismatches was 3.2 (0-6). None was immunized. Recipients and donors were all EBV IgG positive and CMV IgG positive. All but 1 case were induced with basiliximab. The mean graft and patient survival time was 16.6 months (6-26). The mean cold ischemic time was 2.27 hours (1-3.32). The mean serum creatinine at discharge was 241.87 μmol/L (115.18-1063.2), at 6 months was 117.20 μmol/l (95.6-139.9), at 12 months was 104.55 μmol/L (62.02-132.9), and at 24 months was 104.55 μmol/L (62.02-132.9). The mean cyclosporine through level (C0) at 6 months was 137.57 ng/mL (70-366), at 12 months was 117.33 ng/mL (62-197), and at 24 months was 78 ng/mL. The mean cyclosporine 2-hour post-administration concentration levels (C2) at 6 months was 764.9 ng/mL (430-1421), at 12 months was 937.17 ng/mL (483-1292), and at 24 months was 690.66 ng/mL (488-853). Main complications were sepsis, adenovirus hemorrhagic cystitis, new-onset diabetes after transplantation, delayed graft function, polycythemia, and cytomegalovirus infection. No clinical rejection was diagnosed over the 2-year period. Patient and graft survival was 100% at a mean post-transplantation time of approximately 16.6 months. Copyright © 2015 Elsevier Inc.

    From a theoretical point of view, an alloimmune response can not take place, still some type of standard immunosuppression is used in about 60% of patients receiving kidney grafts from their monozygotic twins. We aimed at assessing clinical response in patients receiving renal grafts from a living monozygotic twin donor when no immunosuppressive therapy is used. This is a retrospective observational study of patients receiving kidney grafts from their monozygotic twins from 1969 to 2013. The following data were recorded: age, renal graft recipient's primary disease, renal function, renal survival and overall survival. Immunosuppressive therapy included a single intraoperative dose of methylprednisolone 500 mg and no maintenance immunosuppression. Five patients with kidney grafts from their monozygotic twins were dentified in our centre. Mean age at transplantation was 33 years (27-39). One-year overall survival and graft survival were 100%. Mean creatinine level was 0.96 ± 0.2 one year after transplantation, and 1.2 ± 0.37 mg/dl at most recent follow-up. Two patients died with a functional graft more than 15 years after kidney transplantation (causes were melanoma and cardiovascular event respectively). Follow-up was lost in a patient one year after transplantation. Two patients are alive with a functioning graft at 18 months and 42.5 years after transplantation respectively. Kidney transplantation from a living monozygotic twin is associated to outstanding clinical outcomes. Immunossuppresive therapy to suppress alloimmune response in probably unnecessary 11 zygosity has been confirmed. Copyright © 2015 The Authors. Published by Elsevier España, S.L.U.

    Full Text Available Background: Kidney transplantation is the best treatment option for kidney failure. Major medical progress has been made in the field of renal transplantation over the last 40 years. The surgical procedure has been standardized and the complication rate is low. Overall, the outcome of renal transplantation is excellent and has improved over time. Vascular complications after renal transplantation are the most frequent type of complication following urological complications. Renal artery spasm (RAS following manipulation of renal artery is a common problem during live donor nephrectomy (LDN. The aim of this study was to determine whether or not it is necessary to wait for reverse of RAS and resumption of urinary flow before nephrectomy. Materials and Methods: In this clinical trial 16 cases of LDN who developed RAS during surgery received intra-arterial injection of 40 mg papaverine. In 8 cases surgery continued towards nephrectomy and in other 8 cases we waited for reverse of RAS. All analyses were performed using SPSS-11. Results: In both groups urinary flow started a few minutes (Mean, 12 min after declamping of transplanted kidney and normal renal consistency and color were achieved. There was no significant difference between urinary volume during 12 h after transplantation in two groups. Conclusion: The results showed that it might not be necessary to wait for reverse of RAS before LDN. Both patient (less anesthesia complications and hospital (less expenses will benefit from this time saving.

    There are limited data about sarcopenic obesity in liver transplant recipients. Living donor liver transplant recipients with at least 12 months of follow-up were included. Metabolic syndrome (MS) was defined as ≥ 3 ATP III criteria. Body composition was assessed by bioelectrical impedance. Immunosuppression protocol included short-term steroids, mycophenolate and calcineurin inhibitors (mainly tacrolimus). Data are shown as percentage, mean ± SD, or median (25-75 IQR). The study comprised 82 patients (males 69), aged 50.5 ± 10.65 yr, and follow-up 24 (12-38.5) months. Etiology for cirrhosis was alcohol 29%, hepatitis C 22%, hepatitis B 17%, cryptogenic 24%, and others 7%. Post-transplant sarcopenic obesity was present in 72 (88%), and MS was present in 43 (52%) of recipients with no significant difference among etiologies. There were significant differences between pre- and post-transplant body mass index, triglycerides, high-density lipoprotein, low-density lipoprotein (p = 0.000 for all), prevalence of hypertension (18% vs. 39%), and diabetes (20% vs. 56%). Patients with sarcopenic obesity had significantly higher body mass index, waist circumference, and MS (57% vs. 20%, p = 0.041) when compared to patients without sarcopenic obesity. Despite resuming routine activities, the majority of liver transplant recipients develop sarcopenic obesity and MS. The importance and role of appropriate nutrition and exercise after transplantation merits further investigation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    AIM: To investigate the impact of renal and graft function on post-transplant hyperlipidemia (PTHL) in living donor liver transplantation (LDLT). METHODS: A total of 115 adult patients undergoing LDLT from January 2007 to May 2009 at a single center were enrolled. Data were collected and analyzed by the China Liver Transplant Registry retrospectively. PTHL was defined as serum triglycerides ≥ 150 mg/dL or serum cholesterol ≥ 200 mg/dL or the need for pharmacologic treatment at the sixth month after LDLT. Early renal dysfunction (ERD) was defined as serum creatinine ≥ 2 mg/dL and/or the need for renal replacement therapy in the first post-transplant week. RESULTS: In 115 eligible patients, the incidence of PTHL was 24.3%. Recipients with PTHL showed a higher incidence of post-transplant cardiovascular events compared to those without PTHL (17.9% vs 4.6%, P = 0.037). Serum creatinine showed significant positive correlations with total serum triglycerides, both at post-transplant month 1 and 3 (P transplant serum creatinine levels (P transplant renal insufficiency (P transplant serum creatinine, graft-to-recipient weight ratio, graft volume/standard liver volume ratio, body mass index (BMI) and ERD were identified as risk factors for PTHL by univariate analysis. Furthermore, ERD [odds ratio (OR) = 9.593, P transplant renal dysfunction, which mainly results from pre-transplant renal insufficiency, contributes to PTHL. PMID:23323005

  19. Successful laparoscopic splenectomy after living-donor liver transplantation for thrombocytopenia caused by antiviral therapy

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Although interferon (IFN) based therapy for recurrent hepatitis C virus (HCV) infection after liver transplantation has been widely accepted, it induces various adverse effects such as thrombocytopenia, resulting in its interruption. Recently, concomitant splenectomy at the time of living donor liver transplantation (LDLT) has been tried to overcome this problem, but this procedure leads to several complications such as excessive intraoperative bleeding and serious infection. A 60-year-old female received LDLT using a left lobe graft from her second son for liver failure caused by hepatitis C-related cirrhosis. Six months after LDLT, she was diagnosed as recurrent HCV infection by liver biopsy. IFN monotherapy was started from 7 mo after LDLT and her platelet count decreased to less than 50000/μL, which thus made it necessary to discontinue the treatment. We decided to attempt laparoscopic splenectomy (LS) under general anesthesia. Since intra-abdominal findings did not show any adhesion formations around the spleen, LS could be successfully performed. After LS, since her platelet count immediately increased to 225000/μL 14 d after operation, IFN therapy was restarted and we could convert the combination therapy of IFN and ribavirin, resulting in no detectable viral marker. In conclusion, LS can be performed safely even after LDLT, and LS after LDLT is a feasible and less invasive modality for thrombocytopenia caused by antiviral therapy.

    Sarcopenia is characterized by muscle mass depletion and decrease in muscle power or physical activity. We previously reported that low skeletal muscle mass (SMM) is closely involved with posttransplant mortality in patients undergoing living donor liver transplantation (LDLT). The aim of this study was to prospectively investigate the effects of pretransplant sarcopenia on survival and examine sequential changes in sarcopenic parameters after LDLT. Sarcopenia was defined by measuring SMM using a multifrequency body composition analyzer and assessing grip strength (GS) in 72 adults who underwent LDLT at Kyoto University Hospital between January 2013 and October 2015. The effects of pretransplant sarcopenia on short-term survival and sequential changes in SMM and GS were prospectively analyzed. Of 72 patients, 10 (14%) were defined as having pretransplant sarcopenia. Overall survival rates were significantly lower in patients with sarcopenia (n = 10) than those without sarcopenia (n = 62; P sarcopenia is closely associated with short-term survival after LDLT and that GS recovers before SMM.

    BACKGROUND: Human CD8+CD28- T-suppressor (Ts) cells have been considered to indicate a reduced need for immunosuppression in pediatric liver-intestine transplant recipients and recipients of deceased heart-kidney transplants. However, in adult-to-adult living donor liver transplantation (A-A LDLT) little information is available and the clinical signiifcance is still unknown. METHODS: Flow cytometry was used to detect the population of CD8+CD28- Ts cells present in peripheral blood in A-A LDLT recipients (n=31), patients with end-stage liver disease (n=24) and healthy controls (n=19). Meanwhile, we tested the graft function and trough levels of immunosuppression in recipients. The clinical and follow-up data of 31 transplant recipients were analyzed. RESULTS: Compared with diseased controls (P=0.007) and healthy individuals (P=0.000), a notable expansion of CD8+CD28- Ts cells was found in recipients of A-A LDLT. This was associated with graft function, levels of immunosuppression and rejection episodes. CONCLUSIONS: To monitor the CD8+CD28- Ts cells levels is important to evaluate the immune state of recipients. Meanwhile, it is also important to promote expansion of CD8+CD28- Ts cells in recipients of A-A LDLT, not only to sustain good graft function and decrease the dosage of immunosuppressants, but also to reduce the occurrence of rejection.

    AIM: To discuss the use of mycophenolate mofetil (MMF) as an immunosuppressant in steroid resistant rejection after liver transplantation. METHODS: The clinical records of 260 adult patients who underwent living donor liver transplantation (LDLT) were reviewed. Tacrolimus and methylprednisolone were used for primary immunosuppression. Acute rejection was first treated with steroids. When steroid resistance occurred, the patient was treated with a combination of steroids and MMF. Anti-T-cell monoclonal antibody was administered to patients who were not responsive to steroids in combination with MMF.RESULTS: A total of 90 (35%) patients developed acute rejection. The median interval time from transplantation to the first episode was 15 d. Fifty-four patients were steroid resistant. Forty-four patients were treated with MMF and the remaining 10 required anti-T-cell monoclonal antibody treatment. Progression to chronic rejection was observed in one patient. Bone marrow suppression and gastrointestinal symptoms were the most common side effects associated with MMF use. There was no significant increase in opportunistic infections. CONCLUSION: Our results demonstrate that MMF is a potent and safe immunosuppressive agent for rescue therapy in patients with acute rejection after LDLT.

    Full Text Available Objective. To assess the long-term graft survival of right-sided retroperitoneoscopic live donor nephrectomy (RPLDN, we compared the outcomes of right- and left-sided RPLDN. Methods. Five hundred and thirty-three patients underwent live donor renal transplantation with allografts procured by RPLDN from July 2001 to August 2010 at our institute. Of these, 24 (4.5% cases were selected for right-sided RPLDN (R-RPLDN according to our criteria for donor kidney selection. Study variables included peri- and postoperative clinical data. Results. No significant differences were found in the recipients' postoperative graft function and incidence of slow graft function. Despite significant increased warm ischemic time (WIT: mean 5.9 min versus 4.7 min, in R-RPLDN compared to that in L-RPLDN, there was no significant difference between the two groups regarding long-term patient and graft survival. The complication rate in R-RPLDN was not significantly different compared to that in L-RPLDN (17% versus 6.5%, . No renal vein thrombosis was experienced in either groups. Conclusions. Although our study was retrospective and there was only a small number of R-RPLDN patients, R-RPLDN could be an option for laparoscopic live donor nephrectomy because of similar results, with the sole exception of WIT, in L-RPLDN, and its excellent long-term graft outcomes.

    To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

    Direct-acting antivirals (DAAs) are relatively safe and highly effective for the eradication of hepatitis C virus (HCV) in liver transplant recipients. In this case study, we present a female with a graft reinfected with HCV genotype 2 who was treated with a combination of sofosbuvir and ribavirin after living donor liver transplantation (LDLT). Because the graft was from a hepatitis B core antibody-positive donor, passive immunization with hyperimmune hepatitis B immunoglobulin (HBIG) and entecavir were also provided to prevent hepatitis B virus (HBV) reactivation. It became clear that the combination of sofosbuvir and ribavirin promptly led to a sustained virologic response and that this combination was safe to treat graft reinfection with HCV genotype 2 after LDLT. Adverse events caused by DAAs were not observed, except for slight anemia. HBIG and entecavir were useful in the prevention of HBV reactivation. In conclusion, the present case indicated that DAA treatment for graft reinfection with HCV is safe and effective in LDLT from hepatitis B core antibody-positive donors. PMID:27721720

    Living renal donors undergo an extensive examination program. These examinations should be as safe, gentle, and patient friendly as possible. To compare computed tomography angiography (CTA) and an extensive magnetic resonance imaging (MRI) protocol without contrast agents to observations from nephrectomy in living renal donors and to evaluate whether noncontrast-enhanced MRI can replace CTA for vessel assessment in living renal donors. CTA and MRI results were compared to observations from nephrectomy, which served as the reference standard. Fifty-one potential kidney donors underwent imaging, and 31 donated a kidney. Comparisons in sensitivity, specificity, and accuracy were made with respect to the number of arteries, early branching, and the number of veins. Agreement was assessed using Cohen's kappa. The exact McNemar's test was used to test for statistically significant differences. In the assessment of more than one renal artery, the sensitivity and specificity of MRI and CTA were high and in perfect agreement compared to observations from surgery. The results for both MRI and CTA were as follows: (sensitivity 100%/specificity100%/accuracy 100%/Kappa = 1/P = 1). When comparing the ability to test for early branching we found, MRI: (sensitivity 33%/specificity 100%/accuracy 87%/Kappa = 0.45/P = 1) and CTA: (sensitivity 50%/specificity 100%/accuracy 90%/Kappa = 0.62/P = 1). When used to depict supernumerary veins, we found MRI: (sensitivity60%/specifivity100%/accuracy 93%/Kappa = 0.72/P = 1), whereas CTA showed: (sensitivity 40%/specificity 96%/accuracy 87% Kappa = 0.43/P = 1). In conclusion, an optimized MRI protocol that includes noncontrast-enhanced magnetic resonance angiography can be substituted for CTA for preoperative assessment of the renal vessels before living donor nephrectomy.

    Pediatric LDLT using donors with unfavorable vascular anatomy is challenging in terms of donor safety, and complexity of reconstruction in the recipient. We describe an innovative technique of hepatic venous outflow reconstruction involving the recipient RHV, in the presence of a rudimentary RHV in the donor. The postoperative course of the donor and recipient was uneventful with satisfactory venous outflow in both. This technique avoided the use of prosthetic material, an important consideration given the recipient age and requirement for growth. This shows that donors previously considered unsuitable for donation can be utilized safely as long as principles of vascular anastomosis are adhered to. Moreover, it highlights that innovation is sometimes necessary to avoid compromise in donor safety.

    To describe the anatomical variation occurring in intrahepatic bile ducts (IHDs) in terms of their branching patterns, and to determine the frequency of each variation. The study group consisted of 300 consecutive donors for liver transplantation who underwent intraoperative cholangiography. Anatomical variation in IHDs was classified according to the branching pattern of the right anterior and right posterior segmental duct (RASD and RPSD, respectively), and the presence or absence of the first-order branch of the left hepatic duct (LHD), and of an accessory hepatic duct. The anatomy of the intrahepatic bile ducts was typical in 63% of cases (n=188), showed triple confluence in 10% (n=29), anomalous drainage of the RPSD into the LHD in 11% (n=34), anomalous drainage of the RPSD into the common hepatic duct (CHD) in 6% (n=19), anomalous drainage of the RPSD into the cystic duct in 2% (n=6), drainage of the right hepatic duct (RHD) into the cystic duct (n=1), the presence of an accessory duct leading to the CHD or RHD in 5% (n=16), individual drainage of the LHD into the RHD or CHD in 1% (n=4), and unclassified or complex variation in 1% (n=3)

    Full Text Available Background: Living liver donation is becoming a more common means to treat patients with liver failure because of a shortage of cadaveric organs and tissues. There is a potential for morbidity and mortality, however, in patients who donate a portion of their liver. The purpose of this study is to identify anesthetic complications and morbidity resulting from living liver donor surgery. Patients and Methods: The anesthetic records of all patients who donated a segment of their liver between January 1997 and January 2006 at University of Minnesota Medical Center-Fairview were retrospectively reviewed. The surgical and anesthesia time, blood loss, hospitalization length, complications, morbidity, and mortality were recorded. Data were reported as absolute values, mean ± SD, or percentage. Significance (P < 0.05 was determined using Student′s paired t tests. Results: Seventy-four patients (34 male, 40 female, mean age = 35.5 ± 9.8 years donated a portion of their liver and were reviewed in the study. Fifty-seven patients (77% donated the right hepatic lobe, while 17 (23% donated a left hepatic segment. The average surgical time for all patients was 7.8 ± 1.5 hours, the anesthesia time was 9.0 ± 1.3 hours, and the blood loss was 423 ± 253 ml. Forty-six patients (62.2% received autologous blood either from a cell saver or at the end of surgery following acute, normovolemic hemodilution, but none required an allogenic transfusion. Two patients were admitted to the intensive care unit due to respiratory depression. Both patients donated their right hepatic lobe. One required reintubation in the recovery room and remained intubated overnight. The other was extubated but required observation in the intensive care unit for a low respiratory rate. Twelve patients (16.2% had complaints of nausea, and two reported nausea with vomiting during their hospital stay. There were four patients who developed complications related to positioning during the

    Many transgenes are silenced in mammalian cells (donor cells used for somatic cell nuclear transfer [SCNT]). Silencing correlated with a repressed chromatin structure or suppressed promoter, and it impeded the production of transgenic animals. Gene transcription studies in live cells are challenging because of the drawbacks of reverse-transcription polymerase chain reaction and fluorescence in situ hybridization. Nano-flare probes provide an effective approach to detect RNA in living cells. We used 18S RNA, a housekeeping gene, as a reference gene. This study aimed to establish a platform to detect RNA in single living donor cells using a Nano-flare probe prior to SCNT and to verify the safety and validity of the Nano-flare probe in order to provide a technical foundation for rescuing silenced transgenes in transgenic cloned embryos. We investigated cytotoxic effect of the 18S RNA-Nano-flare probe on porcine fetal fibroblasts, characterized the distribution of the 18S RNA-Nano-flare probe in living cells and investigated the effect of the 18S RNA-Nano-flare probe on the development of cloned embryos after SCNT. The cytotoxic effect of the 18S RNA-Nano-flare probe on porcine fetal fibroblasts was dose-dependent, and 18S RNA was detected using the 18S RNA-Nano-flare probe. In addition, treating donor cells with 500 pM 18S RNA-Nano-flare probe did not have adverse effects on the development of SCNT embryos at the pre-implantation stage. In conclusion, we established a preliminary platform to detect RNA in live donor cells using a Nano-flare probe prior to SCNT.

    We evaluated the factors affecting changes in the postoperative glomerular filtration rate (GFR) after unilateral nephrectomy in living kidney donors and patients with renal disease. We studied 141 subjects who underwent living donor nephrectomy for renal transplantation (n=75) or unilateral nephrectomy for renal diseases (n=66). The GFR of the individual kidney was determined by Tc-99m DTPA scintigraphy before and after nephrectomy. By performing multiple linear regression analysis, we evaluated the factors that are thought to affect changes in GFR, such as age, sex, body mass index (BMI), preoperative GFR, preoperative creatinine level, operated side, presence of diabetes mellitus (DM), presence of hypertension (HTN), and duration of follow-up. In both the donor nephrectomy and the disease nephrectomy groups, GFR increased significantly after nephrectomy (46.9{+-}8.4 to 58.1{+-}12.5 vs. 43.0{+-}9.6 to 48.6{+-}12.8 ml/min, p<0.05). In the donor nephrectomy group, age was significantly associated with change in GFR ({beta}=-0.3, P<0.005). In the disease nephrectomy group, HTN, preoperative creatinine level, and age were significantly associated with change in GFR ({beta}=-6.2, p<0.005; {beta}=-10.9, p<0.01; {beta}=-0.2, p<0.01, respectively). This compensatory change in GFR was not significantly related to sex, duration of follow-up, or operated side in either group. The compensatory change in the GFR of the remaining kidney declined with increasing age in both living kidney donors and patients with renal disease.

    The problem of graft size is one of the critical factors limiting the expansion of adult-to-adult living donor liver transplantation (LDLT). We compared the outcome of LDLT recipients who received grafts with a graft-to-recipient weight ratio (GRWR) or = 0.8%, and we analyzed the risk factors affecting graft survival after small-for-size grafts (SFSGs) were used. Between June 1997 and April 2008, 427 patients underwent LDLT with right lobe grafts at the Department of Surgery of Samsung Medical Center. Recipients were divided into 2 groups: group A with a GRWR or = 0.8% (n = 392). We retrospectively evaluated the recipient factors, donor factors, and operative factors through the medical records. Small-for-size dysfunction (SFSD) occurred in 2 of 35 patients (5.7%) in group A and in 14 of 392 patients (3.6%) in group B (P = 0.368). Graft survival rates at 1, 3, and 5 years were not different between the 2 groups (87.8%, 83.4%, and 74.1% versus 90.7%, 84.5%, and 79.4%, P = 0.852). However, when we analyzed risk factors within group A, donor age and middle hepatic vein tributary drainage were significant risk factors for graft survival according to univariate analysis (P = 0.042 and P = 0.038, respectively). Donor age was the only significant risk factor for poor graft survival according to multivariate analysis. The graft survival rates of recipients without SFSD tended to be higher than those of recipients with SFSD (85.3% versus 50.0%, P = 0.074). The graft survival rates of recipients with grafts from donors grafts from donors > or = 44 years old (92.2% versus 53.6%, P = 0.005). In conclusion, an SFSG (GRWR graft from a donor younger than 44 years.

    Volume mismatch is encountered when a single live donor cannot provide adequate graft volume to the recipient with a remnant liver volume which is safe for donation. Our objective is to present our experience in living donor liver transplantation using dual grafts. Record review of 4 dual graft recipients was done. The results were compared with 122 consecutive patients who received a single right lobe. All dual graft recipients were surviving with satisfactory liver function at a median follow-up of 21 months. Two recipients received 1 right and 1 left lobe graft, while the other 2 recipients received 2 left lobe grafts. One donor developed biloma and was managed by percutaneous drainage. The first recipient required re-laparotomy for postoperative bleeding. The second recipient underwent re-laparotomy for bile leak. The third recipient developed grade II decubitus ulcers due to a prolonged sedentary position. When compared with recipients who received a single right lobe, the operative time was prolonged in the dual graft group. There was no apparent increase in the rate of vascular and biliary complications or the incidence of acute cellular rejection. Actuarial patient survivals were comparable in both groups. Dual graft transplantation provides sufficient volume in the recipient without jeopardizing donor safety.

  15. Reducing biliary complications in adult-to-adult living donor liver transplantation using right lobe graft: experience of 124 cases

    The aim of this paper is to summarize our experience of using right lobe liver grafts to reduce biliary complications in adult-to-adult(A-A)living donor liver transplantation(LDLT).From January 2002 to October 2007,124 adult patients underwent living donor liver transplantation using right lobe grafts at the West China Hospital,Sichuan University Medical School,China.There was no death in all donors.Biliary reconstruction for 178 hepatic duct orifices from 124 donor grafts was performed which included 106 reconstructions of duct-toduct anastomoses and 72 cholangiojejunostomy.Nine recipients had biliary complications including six bile leakages(four from the anastomotic site and two from the cut surface of the liver graft)and three biliary strictures.With the improved techniques for biliary reconstruction,we have achieved good results in 124 recipients of A-A LDLT.We ascribe our success to the introduction of microsurgical techniques and the use of fixed operators which help in decreasing the biliary complications of LDLT.

    This study indicates that intentional portal pressure control under 20 mmHg can improve patient survival not only for recipients of small-for-size grafts but also in classically appropriately sized grafts undergoing A-LDLT. In a retrospective analysis of 100 transplants with intentional portal pressure control, we found that patient survival was significantly better at an even lower final portal pressure of 15 mmHg. As a result, we have adjusted our target portal pressure control protocol, targeting a final portal pressure below 15 mmHg. Portal pressure control allows living donors to donate the smaller left lobe in many cases, which is safer in terms of living donors' post-operative morbidity. As intentional portal pressure control can overcome size-mismatching between the donor and recipient, we propose that it may also be applied to deceased donor liver grafts and in the split-liver transplant setting when the graft size is considered small for the recipient. Intentional portal pressure control can be applied in many liver transplantation situations to overcome small-for-size problems.

    To evaluate the association of oocyte donor-recipient characteristics, oocyte donor response, and live birth pregnancy rate following fresh donor oocyte IVF-ET. Retrospective cohort study. Academic reproductive medicine practice. Two hundred thirty-seven consecutive fresh donor oocyte IVF-ET cycles from January 1, 2007 to December 31, 2013 at the Massachusetts General Hospital Fertility Center. None. Live birth rate per cycle initiated. The mean (±SD) age of oocyte donors and recipients was 27.0 ± 3.7 and 41.4 ± 4.6 years, respectively. Oocyte donor demographic/reproductive characteristics, ovarian reserve testing, and peak serum E2 during ovarian stimulation were similar among cycles which did and did not result in live birth, respectively. Overall implantation, clinical pregnancy, and live birth pregnancy rates per cycle initiated were 40.5%, 60.8%, and 54.9%, respectively. The greatest probability of live birth was observed in cycles with >10 oocytes retrieved, mature oocytes, oocytes with normal fertilization (zygote-two pronuclear stage), and cleaved embryos. The number of oocytes (total and mature), zygotes, and cleaved embryos are associated with live birth following donor oocyte IVF cycles. These findings suggest that specific peri-fertilization factors may be predictive of pregnancy outcomes following donor oocyte IVF cycles. Copyright © 2017 American Society for Reproductive Medicine.

    Urea cycle defects are a group of metabolic disorders caused by enzymatic disruption of the urea cycle pathway, transforming nitrogen to urea for excretion from the body. Severe cases present in early infancy with life-threatening metabolic decompensation, and these episodes of hyperammonemia can be fatal or result in permanent neurologic damage. Despite the progress in pharmacologic treatment, long-term survival is poor especially for severe cases. Liver transplant is an alternative treatment option, providing sufficient enzymatic activity and decreasing the risk of metabolic decompensation. Three patients with urea cycle defects received related living-donor liver transplants at our hospital. Patients presented with late-onset ornithine transcarbamylase deficiency, argininosuccinate lyase deficiency, and citrullinemia. Maximum pretransplant ammonia levels were between 232 and 400 μmol/L (normal range is 18-72 μmol/L), and maximum posttransplant values were 52 to 94 μmol/L. All patients stopped medical treatment and dietary protein restriction for urea cycle defects after transplant. The patient with late-onset ornithine transcarbamylase deficiency already had motor deficits related to recurrent hyperammonemia attacks pretransplant. A major improvement could not be achieved, and he is wheelchair dependent at the age of 6 years. The other 2 patients had normal motor and mental skills before transplant, which have continued 12 and 14 months after transplant. Hepatic artery thrombosis in the patient with the ornithine transcarbamylase deficiency, intraabdominal infection in the patient with argininosuccinate lyase deficiency, and posterior reversible encephalopathy syndrome in the patient with citrullinemia were early postoperative complications. Histopathologic changes in livers explanted from patients with ornithine transcarbamylase deficiency and citrullinemia were nonspecific. The argininosuccinate lyase-deficient patient had portoportal fibrosis and cirrhotic

    Pre-existing humoral barriers challenge the transplantation of living donor kidneys (LDK) into highly sensitized ABO- and human leukocyte antigen (HLA)-incompatible recipients. Conditioning these LDK recipients' immune systems is required before they undergo transplantation. We hypothesized that medical desensitization would yield higher post-transplantation rates of infection. We conducted a study in which matched controls consisting of non-desensitized (NDS) LDK recipients were compared with desensitized (DS) receipients. Pre-transplantation desensitization included treatment with rituximab and mycophenolate mofetil followed by intravenous immunoglobulin (IVIg) and plasmapheresis. All participants in the study underwent induction therapy and maintenance immunosuppression. Primary outcomes included infection (opportunistic, local, systemic) within 12 mo after transplantation. Twenty-five patients underwent desensitization and LDK transplantation. Graft survival in the DS and NDS groups of patients was 96% and 98%, respectively. The mean 3- and 12-mo serum creatinine concentrations in the DS and NDS groups were 1.1±0.2 mg/dL and 1.2±0.3 mg/dL and 0.95±0.4 mg/dL and 0.73±0.8 mg/dL (p=0.3 and p=0.01), respectively. Thirty-six percent of the patients in the DS group had one or more infections, vs. 28% of those in the NDS group (p=0.1). No difference was observed in the frequency of opportunistic or systemic infections in the two groups. Local infections were statistically significantly more frequent in the DS group (60% vs. 30%, respectively; p=0.02). Pre-operative desensitization in highly sensitized LDK recipients is followed by a similar incidence of opportunistic and systemic infections as in NDS patients. Local infections were significantly more frequent in the DS than in the NDS patients in the study. With careful monitoring of infectious complications, pre-transplant desensitization permits LDK transplantation into highly sensitized patients.

    Large vein allografts are suitable for middle hepatic vein (MHV) reconstruction, but their supply is often limited. Although polytetrafluoroethylene (PTFE) grafts are unlimitedly available, their long-term patency is relatively poor. We intended to enhance the clinical usability of PTFE grafts for MHV reconstruction during living donor liver transplantation (LDLT). Two sequential studies were performed. First, PTFE grafts were implanted as inferior vena cava replacements into dogs. Second, in a 1-year prospective clinical trial of 262 adults undergoing LDLT with a modified right lobe, MHV reconstruction with PTFE grafts was compared with other types of reconstruction, and the outcomes were evaluated. In the animal study, PTFE grafts induced strong inflammatory reactions and luminal thrombus formation, but the endothelial lining was well developed. In the clinical study, the reconstruction techniques were revised to make a composite PTFE graft with an artery patch on the basis of the results of the animal study. MHVs were reconstructed with cryopreserved iliac veins (n = 122), iliac arteries (n = 43), aortas (n = 13), and PTFE (n = 84), and these reconstructions yielded 6-month patency rates of 75.3%, 35.2%, 92.3%, and 76.6%, respectively. The overall 6-month patency rates for the iliac vein and PTFE grafts were similar (P = 0.92), but the 6-month patency rates with vein segment 5 were 51.0% and 34.7%, respectively (P = 0.001). The overall graft and patient survival rates did not differ among these 4 groups. In conclusion, ringed PTFE grafts combined with small vessel patches showed high patency rates comparable to those of iliac vein grafts; thus, they can be used for MHV reconstruction when other sizable vessel allografts are not available.

    BACKGROUND: In adult-to-adult living donor liver trans-plantation (LDLT), the use of a right lobe graft without the middle hepatic vein (MHV) can cause hepatic congestion and disturbance of venous drainage. To solve this problem, we successfully used cadaveric venous allografts preserved in 4 ℃ University of Wisconsin (UW) solution within 10 days as interposition veins for drainage of the paramedian portion of the right lobe in adult LDLT. METHODS: From June 2007 to January 2008, 11 adult LDLT patients received modified right liver grafts. The major MHV tributaries (greater than 5 mm in diameter) of 9 cases were preserved and reconstructed using cadaveric interposition vein allografts that had been stored for 1 to 10 days in 4 ℃ UW solution. The regeneration of the paramedian sector of the grafts and the patency of the interposition vein allografts were examined by Doppler ultrasonography after the operation. RESULTS: MHV tributaries were reconstructed in 9 recipients. Only 1 recipient died of renal failure and severe pulmonary infection on day 9 after transplantation without any hemiliver venous outflow obstruction. The other 8 recipients achieved long-term survival with a median follow-up of 30 months. The cumulative patency rates of the 8 recipients were 63.63% (7/11), 45.45% (5/11), 45.45% (5/11) and 36.36% (4/11) at 3, 6, 12 and 24 months, respectively. Regeneration of the paramedian sectors was equivalent. CONCLUSION: The cadaveric venous allograft preserved in 4 ℃ UW solution within 10 days serves as a useful alternative for interposition veins in facilitating implantation of a right lobe graft and guarantees outflow of the MHV.

    AIM:To investigate the impact of renal and graft function on post-transplant hyperlipidemia (PTHL) in living donor liver transplantation (LDLT).METHODS:A total of 115 adult patients undergoing LDLT from January 2007 to May 2009 at a single center were enrolled.Data were collected and analyzed by the China Liver Transplant Registry retrospectively.PTHL was defined as serum triglycerides ≥ 150 mg/dL or serum cholesterol ≥ 200 mg/dL or the need for pharmacologic treatment at the sixth month after LDLT.Early renal dysfunction (ERD) was defined as serum creatinine ≥ 2 mg/dL and/or the need for renal replacement therapy in the first post-transplant week.RESULTS:In 115 eligible patients,the incidence of PTHL was 24.3%.Recipients with PTHL showed a higher incidence of post-transplant cardiovascular events compared to those without PTHL (17.9% vs 4.6%,P=0.037).Serum creatinine showed significant positive correlations with total serum triglycerides,both at posttransplant month 1 and 3 (P < 0.01).Patients with ERD had much higher pre-transplant serum creatinine levels (P < 0.001) and longer duration of pre-transplant renal insufficiency (P < 0.001) than those without ERD.Pretransplant serum creatinine,graft-to-recipient weight ratio,graft volume/standard liver volume ratio,body mass index (BMI) and ERD were identified as risk factors for PTHL by univariate analysis.Furthermore,ERD [odds ratio (OR) =9.593,P < 0.001] and BMI (OR =6.358,P =0.002) were identified as independent risk factors for PTHL by multivariate analysis.CONCLUSION:Renal function is closely associated with the development of PTHL in LDLT.Post-transplant renal dysfunction,which mainly results from pre-transplant renal insufficiency,contributes to PTHL.

    The aim of this study was to investigate the differences in portal hemodynamics between whole liver transplantation and living donor liver transplantation (LDLT). Twenty patients who underwent LDLT (the L group) and 42 patients who underwent whole liver transplantation (the W group) were enrolled, and colored Doppler ultrasonography was performed preoperatively and on postoperative days (PODs) 1, 3, 5, 7, 30, and 90. The changes in the portal blood flow velocity (PBV) and portal blood flow volume (PBF) were monitored. The graft and spleen sizes were measured with angiographic computed tomography, and upper endoscopy was used to measure esophageal varices on PODs 14, 30, and 90. Although the portal venous pressure (PVP) decreased after graft implantation, it was higher in the L group with a smaller graft size ratio (25.7 ± 5.1 cm H₂O for the L group and 18.5 ± 4.6 cm H₂O for the W group, P transplantation; however, the PBF and PBV peaks were significantly higher in the W group. The postoperative PVP and graft volume were greatly related to PBF on POD 1. Grafts in the L group regenerated rapidly after the operation, and the volume increased from 704 ± 115 to 1524 ± 281 mL as early as 1 month after transplantation. A rapid improvement in splenomegaly was observed in both groups. An improvement in esophageal varices was observed in the W group on POD 14 after transplantation, whereas no change was observed in the L group. The portal venous flow in patients with portal hypertension showed a high perfusion state after LDLT, but in contrast to whole liver transplantation, the PVP elevation after LDLT postponed the closing time of the collateral circulation and affected the recovery from splenomegaly.

    Optimal portal flow is one of the essentials in adequate liver function, graft regeneration and outcome of the graft after right lobe adult living donor liver transplantation (ALDLT). The relations among factors that cause sufficient liver graft regeneration are still unclear. The aim of this study is to evaluate the potential predisposing factors that encourage liver graft regeneration after ALDLT. The study population consisted of right lobe ALDLT recipients from Chang Gung Memorial Hospital-Kaohsiung Medical Center, Taiwan. The records, preoperative images, postoperative Doppler ultrasound evaluation and computed tomography studies performed 6 months after transplant were reviewed. The volume of the graft 6 months after transplant divided by the standard liver volume was calculated as the regeneration ratio. The predisposing risk factors were compiled from statistical analyses and included age, recipient body weight, native liver disease, spleen size before transplant, patency of the hepatic venous graft, graft weight-to-recipient weight ratio (GRWR), posttransplant portal flow, vascular and biliary complications and rejection. One hundred forty-five recipients were enrolled in this study. The liver graft regeneration ratio was 91.2 +/- 12.6% (range, 58-151). The size of the spleen (p = 0.00015), total portal flow and GRWR (p = 0.005) were linearly correlated with the regeneration rate. Patency of the hepatic venous tributary reconstructed was positively correlated to graft regeneration and was statistically significant (p = 0.017). Splenic artery ligation was advantageous to promote liver regeneration in specific cases but splenectomy did not show any positive advantage. Spleen size is a major factor contributing to portal flow and may directly trigger regeneration after transplant. Control of sufficient portal flow and adequate hepatic outflow are important factors in graft regeneration.

    Full Text Available Context: Extensive bleeding associated with liver transplantation is a major challenge faced by transplant surgeons, worldwide. Aims: To evaluate the blood component consumption and determine preoperative factors that predict the same in living donor liver transplantation (LDLT. Settings and Design: This prospective study was performed for a 1 year period, from March 2010 to February 2011. Materials and Methods: Intra- and postoperative utilization of blood components in 152 patients undergoing LDLT was evaluated and preoperative patient parameters like age, gender, height, weight, disease etiology, hemoglobin (Hb, hematocrit (Hct, platelet count (Plt, total leukocyte count (TLC, activated partial thromboplastin time (aPTT, international normalized ratio (INR, serum bilirubin (T. bilirubin, total proteins (T. proteins, albumin to globulin ratio (A/G ratio, serum creatinine (S. creatinine, blood urea (B. urea, and serum electrolytes were assessed to determine their predictive values. Univariate and stepwise discriminant analysis identified those factors, which could predict the consumption of each blood component. Results: The average utilization of packed red cells (PRCs, cryoprecipitates (cryo, apheresis platelets, and fresh frozen plasma was 8.48 units, 2.19 units, 0.93 units, and 2,025 ml, respectively. Disease etiology and blood component consumption were significantly correlated. Separate prediction models which could predict consumption of each blood component in intra and postoperative phase of LDLT were derived from among the preoperative Hb, Hct, model for end-stage liver disease (MELD score, body surface area (BSA, Plt, T. proteins, S. creatinine, B. urea, INR, and serum sodium and chloride. Conclusions: Preoperative variables can effectively predict the blood component requirements during liver transplantation, thereby allowing blood transfusion services in being better prepared for surgical procedure.

    Background Very little is known about the long-term outcomes of African American living kidney donors (AALKDs). We undertook this study to describe renal outcomes of AALKDs several years after donation. Methods We invited 107 AALKDs to come for follow-up health evaluation. Results 39 subjects (36.4%) completed evaluation at a mean of 7.1 +/− 1.6 (range 3.9–10.2) years post-donation. The mean estimated glomerular filtration rate using the abbreviated MDRD equation (eGFR(MDRD)) at followup was 72.1 +/− 16.3 (range 42–106) ml/min per 1.73m2, and 18% of subjects had an eGFR(MDRD) of 30–59. The mean absolute and relative decrease in eGFR(MDRD) from the time of donation to followup were 30.5 +/− 16.4 ml/min per 1.73m2 and 28.8%, respectively. Subjects whose BMI was ≥ 35 kg/m2 (n=8) were found to have a greater decrement in e(MDRD) than those with BMI 300 mcg/mg creatinine), and 6 (15.4%) had microalbuminuria (30–300 mcg/mg creatinine). Conclusions AALKDs experience a substantial incidence of hypertension and a modest drop in eGFR(MDRD) post-donation, and obesity may increase the magnitude of renal decline. Further study is urgently needed to determine the long-term risks of AALKDs. PMID:20029333

    BACKGROUND Previous studies have reported poor graft regeneration after living donor liver transplantation (LDLT) due to inappropriate portal venous flow (PVF). In this study, we investigated the perioperative factors affecting postoperative PVF after LDLT. MATERIAL AND METHODS The perioperative data of 366 LDLT patients were retrospectively reviewed. The average PVF on postoperative days 1, 3, and 5 was measured and dichotomized at a cut-off value for patient survival of 1,477 mL/min. Perioperative variables, including coagulation profiles, were compared between high and low postoperative PVF groups. The factors potentially significant (plow postoperative PVF were evaluated in a univariate analysis, followed by the development of a predictive model for a low postoperative PVF. RESULTS A low post-LDLT PVF was determined in 113 patients (30.9%). The univariate analysis identified systemic hypertension, LDLT duration, average mean blood pressure, and insulin administration as the significantly related factors. Other significant factors were a plasma fibrinogen, at the anhepatic phase and 1 h after graft reperfusion, as well as the platelet count at the anhepatic phase. After multivariate adjustment, plasma fibrinogen 1 h after graft reperfusion against a recipient background of systemic hypertension was independently associated with a low mean postoperative PVF. CONCLUSIONS A low mean PVF during the early post-LDLT period was independently related to the plasma fibrinogen level 1 h after graft reperfusion, and to a history of systemic hypertension. Thus, the practice of aggressive supplementation of plasma fibrinogen during the immediate post-reperfusion period merits serious consideration.

    Full Text Available Lymph leakage is a cause of prolonged fluid discharge in renal transplant patients. Lymph leakage during early post-transplantation is responsible for extracting immune substances; therefore, it may play a role in prognosis of the transplanted kidney. In this study, we aimed to investigate the effects of lymph leakage on different factors that play significant roles in renal allograft outcome. During the present case-control study, we evaluated 62 renal allograft recipients in which 31 subjects were complicated with lymph leakage and enrolled as the study group. The other 31 subjects were included in the control group who did not experience any lymph leakage during their post-transplantation period. All kidneys were transplanted from living donors. We investigated and compared the renal allograft rejection rate, hospitalization duration, serum urea, creatinine (Cr and cyclosporine (CsA levels, antithymoglobin (ATG administration and treatment duration between the study and the control groups. There were no significant difference in the urea and Cr levels between the two groups (P >0.05. Early (one week and late (one month serum CsA levels of the study group were significantly higher than in the control group (P = 0.005 and P = 0.006. The number of days in which ATG receivers responded to therapy was significantly lower for the control group (P = 0.008. 21.93% of the study group subjects experienced allograft rejection, while this rejection probability was 28.38% for the control group (P = 0.799. Lymph leakage has no prominent role in renal function, which is estimated by Cr and urea levels in patients′ serum during the days after transplantation. CsA level was higher in patients with lymph leakage, and all cases of allograft rejection were in the subjects with lymph leakage.

    Background There have been few prospective controlled studies of kidney donors. Understanding the pathophysiological effects of kidney donation is important for judging donor safety and for improving our understanding of the consequences of reduced kidney function in chronic kidney disease. Study Design Prospective, controlled, observational cohort study. Setting & Participants Three-year follow-up of kidney donors and paired controls suitable for donation at their donor’s center. Predictor Kidney donation. Outcomes Medical history, vital signs, glomerular filtration rate and other measurements at 6, 12, 24 and 36 months after donation. Results At 36 months, 182 of 203 (89.7%) original donors and 173 of 201 (86.1%) original controls continue to participate in follow-up visits. The linear slope of the glomerular filtration rate measured by plasma iohexol clearance declined 0.36±7.55 mL/min per year in 194 controls, but increased 1.47±5.02 mL/min per year in 198 donors (P = 0.005) between 6 and 36 months. Blood pressure was not different between donors and controls at any visit, and at 36 months all 24-hour ambulatory blood pressure parameters were similar in 126 controls and 135 donors (mean systolic: 120.0±11.2 [SD] v. 120.7±9.7 mmHg [P=0.6]; mean diastolic: 73.4±7.0 v. 74.5±6.5 mmHg [P=0.2]). Mean arterial pressure nocturnal dipping was manifest in 11.2%±6.6% of controls and 11.3%±6.1% donors (P=0.9). Urinary protein-creatinine and albumin-creatinine ratios were not increased in donors compared to controls. From 6 to 36 months post-donation, serum parathyroid hormone, uric acid, homocysteine and potassium levels were higher, whereas hemoglobin was lower in donors compared to controls. Limitations Possible bias resulting from an inability to select controls screened to be as healthy as donors, short follow-up duration, and drop-outs. Conclusions Kidney donors manifest several of the findings of mild chronic kidney disease. However, at 36 months after

    Purpose: To assess liver remnant volume regeneration and maintenance, and complications in the long-time follow-up of donors after living donor liver transplantation using CT and MRI. Materials and Methods: 47 donors with a mean age of 33.5 years who donated liver tissue for transplantation and who were available for follow-up imaging were included in this retrospective study. Contrast-enhanced CT and MR studies were acquired for routine follow-up. Two observers evaluated pre- and postoperative images regarding anatomy and pathological findings. Volumes were manually measured on contrast-enhanced images in the portal venous phase, and potential postoperative complications were documented. Pre- and postoperative liver volumes were compared for evaluating liver remnant regeneration. Results: 47 preoperative and 89 follow-up studies covered a period of 22.4 months (range: 1 - 84). After right liver lobe (RLL) donation, the mean liver remnant volume was 522.0 ml (± 144.0; 36.1%; n = 18), after left lateral section (LLS) donation 1,121.7 ml (± 212.8; 79.9%; n = 24), and after left liver lobe (LLL) donation 1,181.5 ml (± 279.5; 72.0%; n = 5). Twelve months after donation, the liver remnant volume were 87.3% (RLL; ± 11.8; n = 11), 95.0% (LS; ± 11.6; n = 18), and 80.1% (LLL; ± 2.0; n = 2 LLL) of the preoperative total liver volume. Rapid initial regeneration and maintenance at 80% of the preoperative liver volume were observed over the total follow-up period. Minor postoperative complications were found early in 4 patients. No severe or late complications or mortality occurred. Conclusion: Rapid regeneration of liver remnant volumes in all donors and volume maintenance over the long-term follow-up period of up to 84 months without severe or late complications are important observations for assessing the safety of LDLT donors.

    Objective: To evaluate the performance of magnetic resonance (MR) and multidetector computed tomography (MDCT) in the assessment of living donor's vascular and biliary anatomy, having surgical findings as reference standard. Methods: Thirty-two living liver donors underwent MR cholangiography (1.5-T; standard cholangiography pulse sequences and delayed acquisitions after administration of biliary contrast agent) for biliary anatomy evaluation. MDCT (16-row multidetector scanner, multiphase protocol, 3 mm slice thickness) was also performed in all cases for the assessment of vascular anatomy before transplantation. Hepatic veins (<4 mm in diameter) were not considered. MR and MDCT images interpretation was performed by two reviewers by consensus, based on source axial images, multiplanar reformats, and three-dimensional (3D) postprocessing images. Surgical intraoperative findings were used as standard of reference. Results: At surgery, 17 biliary anomalies, 3 portal anomalies, 32 venous and 8 arterial variants were found in the 32 patients. MR correctly identified 15/17 biliary anomalies, with a sensitivity of 88% and a specificity of 93%. MDCT correctly identified 8/8 arterial, 3/3 portal and 29/32 venous variants, with a sensitivity of 100% and 91%, respectively, and a specificity of 100%. Conclusions: MR and MDCT proved to be efficient in evaluating living liver donor's biliary and vascular anatomy.

    Although it is recognized that hepatobiliary scan is of value in assessing postoperative complications of biliary surgery or cadaveric whole liver transplantation, there have been few reports regarding its usefulness following living donor liver transplantation. We performed living donor liver transplantation in a patient with biliary cirrhosis due to hepatolithiasis, using a right lobe graft from her sister. On the 15th postoperative day, bile discharge appeared from the operative wound. The leakage point could not be identified by computed tomography and cholangiography from the biliary drainage catheter. Hepatobiliary scan with Tc-99m Sn-N-pyridoxyl-5-methyltryptophan (99mTc-PMT) demonstrated biliary extravasation from the left side of the anastomosis of the hepatico-jejunostomy, indicating biliary leakage from the anastomosis. Conservative therapy was continued because the radioisotope flowed smoothly into the reconstructed jejunum and the biliary drainage catheter, and the leakage was stopped on the 63th postoperative day. Hepatobiliary scan is useful in determining the therapeutic plan as well as detection of bile leakage and identification of leakage points after living donor liver transplantation.

    We evaluated factors affecting change in glomerular filtration rate (GFR) after unilateral nephrectomy in living kidney donors and patients with renal disease. We retrospectively reviewed the 435 individuals who underwent unilateral nephrectomy in 2006. Among them, we enrolled 141 patients who had performed 99mTc-DTPA scans before and after surgery. The study population consisted of 75 living donors (M=43, F=32) and 66 patients with renal disease (M=46, F=20). We evaluated factors affecting the GFR change by multiple linear regression analysis. The renal disease group was significantly older than the donors at baseline (53.9{+-}12.9 vs. 37.8{+-}11.1yr, P<0.05) and had higher preoperative Cr level (0.95{+-}0.20 vs. 0.85{+-}0.18mg/dL, p<0.05). The mean duration of the follow-up was 7.3{+-}3.3 months, (p<0.05). The disease group and donors significantly increased the GFR after nephrectomy (43.0{+-}9.6 to 48.6{+-}12.8 vs. 46.9{+-}8.4 to 58.1{+-}12.5 ml/min, respectively, P<0.05). The disease group had significantly lesser mean GFR change than the doners. (5.6{+-}7.2 vs. 11.1{+-}8.5 ml/min, respectively, p<0.05). In the renal disease group, multiple regression analysis showed that preop Cr level and age were significantly associated with GFR change ({beta} =-12.53, p=0.003; {beta} =-0.19, p=0.004). In the donor group, age was significantly associated with the GFR change ({beta} =-0.265, p=0.002). But change of GFR was not associated with sex, preop GFR, BMI, duration of follow-up, site of nephrectomy in both groups. Age and preoperative renal function were predictive factors affecting change in GFR after unilateral nephrectomy.

    Preoperative donor liver biopsy is the criterion standard to verify the quality of a liver. However, it can cause some complications, thus this study was designed to know whether selective liver biopsy is possible or not, and to find a subgroup that does not require preoperative biopsy. We reviewed preoperative images and postoperative outcome in 118 donors from September 2013 to January 2014. Visual grading of steatosis on plain computed tomography (CT) was performed and compared steatosis on preoperative liver biopsy was done within 7 days from the CT scan. Visual grades of plain CT were 1 (n = 50, 42.4%), 2 (n = 47, 39.8%), 3 (n = 13, 11.0%), 4 (n = 7, 5.9%), and 1 (n = 1, 0.8%). Macrovesicular steatosis on liver biopsy according to visual grades were 1 (0.67 ± 1.3%), 2 (1.67 ± 1.8%), 3 (6.23 ± 6.4%), 4 (14.7 ± 16.6), and 5 (30%). Right liver grafts including right lobe, modified right lobe, and extended right lobe were procured in 106 (89.9%) donors, and 16% (17/106) of the donors were visual grades 3, 4, and 5. Eleven donors (64.7%) were accepted for right liver donation after liver biopsy, whereas 6 (35.3%) donors were deemed possible to donate right liver after weight reduction and reevaluation of steatosis. Transient hepatic dysfunction after right hepatectomy was significantly increased according to the increment of visual grade. Preoperative liver biopsy may not be necessary in visual grade 1 or 2 donors, but should be performed for grade 3 and 4 donors based on recipient's urgency so as to decide whether to proceed with right hepatectomy or not.

    "Domino" cardiac procedure is an effective option to increase the donor pool when heart-lung transplantation (HLT) is the only treatment for patients with terminal cardiopneumopathy. We reviewed the long-term outcomes of domino cardiac donors and recipients at our institution. Ten of 35 patients who underwent HLT from 1991 onward served as domino cardiac donors. They included eight female and two male subjects of overall mean age of 33 years and mean weight of 55 kg. Their diagnoses were primary pulmonary hypertension (n = 6) as well as cystic fibrosis, bronchiectasis, Eisenmenger's syndrome, and bronchiolitis obliterans (n = 1 each). The domino cardiac recipients included six males and four females of overall mean age of 47 years and mean weight of 61 kg. They were affected by ischemic heart disease (n = 5), cardiomyopathy (n = 4), and valvular heart disease (n = 1). Mean pulmonary vascular resistance was 3 Wood units. The heart was used either in the orthotopic (n = 8) or in the heterotopic position (n = 2). The 1-, 5-, and 10-year survivals for the domino cardiac donors versus their recipients were 60%, 40%, 30% versus 90%, 70%, 60%, respectively. Five domino donors developed bronchiolitis obliterans syndrome. Among the domino recipients group, cardiac allograft vasculopathy was rare (n = 1). Common causes of late death were in the domino recipients infections in the domino donors (n = 2) and malignancies. Our experience suggested good long-term results of the domino procedure.

    AIM: To investigate the tacrolimus dosage requirements and blood concentrations in adult-to-adult right lobe living donor liver transplantation (AALDLT) recipients with small-for-size (SFS) grafts.METHODS: During January 2007 and October 2008, a total of 54 cases of AALDLT with an observation period of 6 mo were enrolled in this study. The 54 patients were divided into two groups according to graftrecipient body weight ratio (GRBW): SFS grafts group (Group S, GRBW < 0.8%, n = 8) and non-SFS grafts group (Group N, GRBW ≥ 0.8%, n = 46). Tacrolimus 12-hour blood levels and doses were recorded during weeks 1, 2, 3 and 4 and months 2, 3, 4, 5 and 6 in group S and group N. Meanwhile, acute rejection rates,liver and renal function test results, and the number of potentially interacting medications were determined at each interval in the two groups. A comparison of tacrolimus dosage requirements and blood levels were made weekly in the first month post-surgery, and monthly from months 2 to 6.RESULTS: There were no differences in the demographic Demographic characteristics, acute rejection rates, liver and renal function test results, or the number of potentially interacting medications administered between the two groups. The tacrolimus dosage requirements in group S were significantly lower than group N at 2 wk (2.8 ± 0.4 mg/d vs 3.6 ± 0.7 mg/d, P = 0.006), 3 wk (2.9 ± 0.7 mg/d vs 3.9 ± 0.8 mg/d, P = 0.008), 4 wk (2.9 ± 0.8 mg/d vs 3.9 ± 1.0 mg/d, P = 0.023) and 2 mo (2.8 ± 0.7 mg/d vs 3.8 ± 1.1 mg/d, P = 0.033). Tacrolimus 12-h trough concentrations were similar between the two groups at all times except for 2 wk post-transplantation,when the concentrations were significantly greater in group S recipients than in group N recipients (11.3 ± 4.8 ng/mL vs 7.0 ± 3.8 ng/mL, P = 0.026).CONCLUSION: SFS grafts recipients have significantly decreased tacrolimus dosage requirements compared with non-SFS grafts recipients in AALDLT during the first 2 mo post-surgery.

    Full Text Available BACKGROUND: The reoperation rate remains high after liver transplantation and the impact of reoperation on graft and recipient outcome is unclear. The aim of our study is to evaluate the impact of early reoperation following living-donor liver transplantation (LDLT on graft and recipient survival. METHODS: Recipients that underwent LDLT (n = 111 at the University of Tokyo Hospital between January 2007 and December 2012 were divided into two groups, a reoperation group (n = 27 and a non-reoperation group (n = 84, and case-control study was conducted. RESULTS: Early reoperation was performed in 27 recipients (24.3%. Mean time [standard deviation] from LDLT to reoperation was 10 [9.4] days. Female sex, Child-Pugh class C, Non-HCV etiology, fulminant hepatitis, and the amount of intraoperative fresh frozen plasma administered were identified as possibly predictive variables, among which females and the amount of FFP were identified as independent risk factors for early reoperation by multivariable analysis. The 3-, and 6- month graft survival rates were 88.9% (95%confidential intervals [CI], 70.7-96.4, and 85.2% (95%CI, 66.5-94.3, respectively, in the reoperation group (n = 27, and 95.2% (95%CI, 88.0-98.2, and 92.9% (95%CI, 85.0-96.8, respectively, in the non-reoperation group (n = 84 (the log-rank test, p = 0.31. The 12- and 36- month overall survival rates were 96.3% (95%CI, 77.9-99.5, and 88.3% (95%CI, 69.3-96.2, respectively, in the reoperation group, and 89.3% (95%CI, 80.7-94.3 and 88.0% (95%CI, 79.2-93.4, respectively, in the non-reoperation group (the log-rank test, p = 0.59. CONCLUSIONS: Observed graft survival for the recipients who underwent reoperation was lower compared to those who did not undergo reoperation, though the result was not significantly different. Recipient overall survival with reoperation was comparable to that without reoperation. The present findings enhance the importance of vigilant

    Full Text Available Background: The three phases of living donor liver transplantation (LDLT represent different liver conditions. The aim is to study the required end-tidal desflurane concentration (ET-Des guided with entropy monitoring for the depth of anesthesia. Methods: After the Ethics and Research Committee approval, 40 patients were included in this prospective study. Anesthesia was maintained with Desflurane-O2-air. State entropy (SE and Response entropy (RE were kept between 40 and 60. Results: Age and Model for End-stage Liver Disease (MELD score were 45±10 years and 15.43±3.92, respectively. ET-Des were significantly lower in the anhepatic phase (2.8±0.4% than in the pre-anhepatic and neohepatic phases (3.3±0.3%, 3.47±0.3%, respectively, P 0.05. Total operative time was 651±88 minutes, and for each phase it was 276±11, 195±55, and 191±24 minutes, respectively. Significant changes were found in hemoglobin g/dl and hematocrit % between the three phases (10.28±1.5, 30.48±4.3, (9.45±1.34, 28.36±4.1, and (8.88±1.1, 26.63±3.5, P<0.05. The heart rate and mean blood pressures were stable despite the cardiac index demonstrated a significant reduction during the anhepatic phase (2.99±0.22 when compared to the pre-anhepatic and neohepatic phases (3.60±0.29 and (4.72±0.32, respectively, ( P<0.05. There was a significant correlation between CI and ET-Des% (r=0.604, P<0.05. Conclusion: Inhalational anesthetic requirements differed from one phase to another during LDLT, with requirements being the least during the anhepatic phase. Monitoring of the anesthesia depth was required, to avoid excess administration, which could compromise the hemodynamics before the critical time of reperfusion.

    Full Text Available Background/AimsThe dose of mycophenolate mofetil (MMF has been reduced in Asia due to side effects associated with the conventional fixed dose of 2-3 g/day. We aimed to determine the pharmacokinetics of a reduced dose of MMF and to validate its feasibility in combination with tacrolimus in living-donor liver transplantation (LDLT.MethodsTwo sequential studies were performed in adult LDLT between October 2009 and 2011. First, we performed a prospective pharmacokinetic study in 15 recipients. We measured the area under the curve from 0 to 12 hours (AUC0-12 for mycophenolic acid at postoperative days 7 and 14, and we performed a protocol biopsy before discharge. Second, among 215 recipients, we reviewed 74 patients who were initially administered a reduced dose of MMF (1.0 g/day with tacrolimus (trough, 8-12 ng/mL during the first month, and 5-8 ng/mL thereafter, with a 1-year follow-up. We performed protocol biopsies at 2 weeks and 1 year post-LDLT.ResultsIn the first part of study, AUC0-12 was less than 30 mgh/L in 93.3% of cases. In the second, validating study, 41.9% of the recipients needed dose reduction or cessation due to side effects within the first year after LDLT. At 12 months post-LDLT, 17.6% of the recipients were administered a lower dose of MMF (0.5 g/day, and 16.2% needed permanent cessation due to side effects. The 1- and 12-month rejection-free survival rates were 98.6% and 97.3%, respectively.ConclusionsA reduced dose of MMF was associated with low blood levels compared to the existing recommended therapeutic range. However, reducing the dose of MMF combined with a low level of tacrolimus was feasible clinically, with an excellent short-term outcome in LDLT.

    To evaluate the effect of low-dose dopamine administration on the early function of the kidney in unrelated kidney donors after transplantation. In this double-blinded clinical trial, 60 adult kidney donors and 60 recipients, younger than 50 years old, were studied. Donors and recipients were randomly divided into two groups; group 1 received dopamine 3 µ/kg/min and group 2 received similar regimen of placebo. During the first 3 days postoperatively, serum levels of urea and creatinine as well as urine output and early kidney function were compared between two groups. Serum levels of creatinine and urea and urine output during the first three days after the operation did not differ statistically significantly between two groups (P = .549, P = .306, and P = .375, respectively). Early kidney function was better significantly in group 1 (5.3 ± 3.2 versus 8.6 ± 8.0 hours; P = .048). Premedication of the kidney transplant donors with low-dose dopamine accelerates early kidney function after transplantation, but has no effect on the hemodynamic status and serum levels of creatinine and urea in the donors.

    LDLT is indicated for a variety of metabolic disorders, primarily in Asian countries due to the absolute scarcity of deceased donor LT. We analyzed data for all pediatric LDLTs performed between November 1989 and December 2010, during which 2224 pediatric patients underwent LDLT in Japan. Of these patients, 194 (8.7%) underwent LDLT for metabolic disorders. Wilson's disease (n = 59; 30.4%) was the most common indication in the patients with metabolic disorders, followed by OTCD (n = 40; 20.6%), MMA (n = 20; 10.3%), and GSD (n = 15; 7.7%). The one-, five-, 10-, and 15-yr patient and graft survival rates were 91.2%, 87.9%, 87.0%, and 79.3%, and 91.2%, 87.9%, 86.1%, and 74.4%, respectively. Wilson's disease and urea cycle deficiency were associated with better patient survival. The use of heterozygous donors demonstrated no negative impact on either the donors or recipients. With regard to X-linked OTCD, symptomatic heterozygote maternal donors should not be considered potential donor candidates. Improving the understanding of the long-term suitability of this treatment modality will require the registration and ongoing evaluation of all patients with inherited metabolic disease considered for LT.

    Purpose: The purpose of this study was to evaluate the blood pool contrast agent gadofosveset for MR angiography (MRA) of the renal vasculature in living kidney donors (LKD). Materials and Methods: Of the 28 consecutive potential LKDs (13 men, 15 women; mean age 55.14 years {+-} 11.97) initially included in this prospective study, 20 patients underwent surgery and were considered for further evaluation. 7 acquisitions of a 3D T1-weighted FLASH sequence were performed following administration of gadofosveset for the assessment of the vascular anatomy and collecting system at predefined time points at 1.5 T. All MR exams were prospectively analyzed by 2 radiologists in consensus mode prior to surgery. In addition, ROI-based relative SNR measurements were performed in the vena cava inferior and abdominal aorta. Results: MR image acquisition was completed in all 20 potential living donors. In 8 donors an additional CT scan was available for further comparison with the collateral anatomy, resulting in a total of 28 analyzed kidneys. MRA disclosed 36 renal arteries, since 8 accessory arteries were found in 8 subjects. One accessory artery and one case of fibromuscular dysplasia were missed by MRA. The venous anatomy and the collecting system were assessed correctly with MRI. In addition, MRI diagnosed two renal cell carcinomas. The overall sensitivity and positive predictive value of gadofosveset-enhanced MRI on a per kidney basis were 92.9 % and 100 %, respectively. Conclusion: Gadofosveset enables accurate evaluation of potential LKDs. (orig.)

    Living donor liver transplantation has become an accepted procedure to overcome the shortage of adult donor organs. The aim of this study was to evaluate the usefulness of hepatobiliary scintigraphy in the diagnosis of complications after adult-to-adult living donor liver transplantation. We analysed 82 hepatobiliary scintigraphy studies performed using technetium-99m DISIDA in 60 adult patients (44 males, 16 females) who had been transplanted with a living donor's hepatic lobe (right lobe, 32; left lobe, 28). Indications for hepatobiliary scintigraphy were abnormal symptoms and/or liver function tests (n=54) or suspected bile leak or biloma (n=28). Median interval between transplantation and scintigraphy was 69 days (9 days to 23 months). Scintigraphic findings were classified into hepatic parenchymal dysfunction, total biliary obstruction, segmental biliary obstruction, bile leak and normal graft. Scintigraphic findings were confirmed by liver biopsy in 17 cases, and by radiological and clinical follow-up in 65 cases. There were 29 events relating to biliary complications (six total biliary obstructions, eight segmental biliary obstructions and 15 bile leaks) and 19 relating to non-biliary complications (15 cases of rejection, two of infection and two of vascular compromise) in 38 patients. Hepatobiliary scintigraphy provided the correct diagnosis in all eight segmental and five of six total biliary obstructions, and in all 15 cases of bile leak. Of the 19 non-biliary complications, 16 showed parenchymal dysfunction regardless of the aetiology and three showed total biliary obstruction on scintigraphy. All but three of 34 normally functioning grafts were normal on scintigraphy. The diagnostic sensitivity and specificity of scintigraphy for biliary obstruction in the 54 patients with abnormal symptoms or liver function tests were 93% (100% for segmental, 83% for total) and 88% (35/40), respectively. The sensitivity and specificity were each 100% (15/15, 13

    Solid organ transplantation has emerged as a life-saving treatment for many patients suffering from end-stage organ failure. Organs have been successfully recovered after a variety of aggressive interventions. We propose that decompressive laparotomy, when clinically indicated, should be considered in the aggressive resuscitation of potential organ donors. A thorough literature review examining aggressive interventions on potential organ donors was conducted after experience with a unique case at this institution. Articles were reviewed for the types of interventions performed as well as the time frame in relation to organ donation. In our case, several ethical issues were raised when considering decompressive laparotomy in a patient pronounced dead by neurologic criteria. We propose that having a surgical intensivist involved in the management of potential donors will further increase the salvage rate, as more invasive resuscitation options are possible.

    Full Text Available In the past, morbid obesity was considered a relative contraindication to renal donation; however, more recent publications have shown that laparoscopic renal surgery is safe and effective for obese donor nephrectomy. We report the performance of a bariatric surgery before the kidney donation in 2 patients in order to improve their medical condition and to reduce their surgical risk to the transplantation procedure. After bariatric surgery, both donors lost more than 30% of their initial corporal weight and their donation procedure was successfully performed, with uneventful postoperative courses.

    BACKGROUND: Living unrelated donor kidney transplantation between spouses is poorer than living related donor kidney transplantation in tissue matching , but clinical practice shows that there is no obvious difference in short-term curative effects between these two types of kidney transplantation.OBJECTIVE: To compare the clinical cu rative effects between living unrelated donor kidney transplantation between spouses and living related donor kidney transplantation and summarize the clinical experience of kidney transplantation between spouses.METHODS: A retrospective clinical data analysis was made regarding 18 patients who received kidney transplantation between spouses and 100 patients who received living related donor kidney transplantation. The clinical curative effects ware compared between these two types of kidney transplantation by analyzing some indices including tissue matching before transplantation and renal fu nction recovery, acute rejection and infection incidence at 1, 3, and 6 months.RESULTS AND CONCLUSION: Tissue matching before transplantation was poorer in 18 patients undergoing kidney transplantation between spouses than in 100 patients undergoing living related donor kidney transplantation. Under the same transplantation proposal and immunosuppressive therapy, there was no significant difference in serum creatinine level, renal function recovery, acute rejection, and infection incidence within 6 months after transplantation between kidney transplantation between spouses and living related donor kidney transplantation (P > 0.05). These findings suggest that the clinical curative effects are similar between living unrelated donor kidney transplantation between spouses and living related donor kidney transplantation.%背景:夫妻间活体肾移植尽管在组织配型方面差于血缘关系供肾移植,但在临床实践观察中夫妻肾移植与血缘关系肾移植间近期疗效并无明显差异.目的:对比同期

    Gastrointestinal (GI) recovery after major abdominal surgery can be delayed from an ongoing need for narcotic analgesia thereby prolonging hospitalization. Enhanced recovery after surgery (ERAS) is a multimodal perioperative care pathway designed to facilitate early recovery after major surgery by maintaining preoperative body composition and physiological organ function and modifying the stress response induced by surgical exposure. Enhanced recovery programs (ERPs) in colorectal surgery have decreased the duration of postoperative ileus and the hospital stay while showing equivalent morbidity, mortality, and readmission rates in comparison to the traditional standard of care. This study is a pilot trial to evaluate the benefits of ERAS protocols in living kidney donors undergoing laparoscopic nephrectomy. This is a single-center, non-randomized, retrospective analysis comparing the outcomes of the first 40 live kidney donors subjected to laparoscopic nephrectomy under the ERAS protocol to 40 donors operated prior to ERAS with traditional standard of care. Our ERAS protocol includes reduced duration of fasting with preoperative carbohydrate loading, intraoperative fluid restriction to 3 ml/kg/hr, target urine output of 0.5 ml/kg/hr, use of subfascial Exparel injection (bupivacaine liposome suspension), and postoperative narcotic-free pain regimen with acetaminophen, ketorolac, or tramadol. Short-term patient outcomes were compared using Pearsons's Chi-Squared test for categorical variables and the Kruskal-Wallis test for continuous variables. Additionally, a multivariate analysis was conducted to evaluate factors influencing patient length of stay and likelihood of readmission. ERAS protocol reduced the postoperative median length of stay decreased from 2.0 to 1.0 days (p=0.001). Overall pain scores were significantly lower in the ERAS group (peak pain score 6.0 vs. 8.00, pdonation through optimizing donor outcomes and perioperative patient satisfaction.

    Full Text Available Background: Coagulopathy after living donor hepatectomy (LDH may endanger donor safety during removal of thoracic epidural catheter (TEC. The present study was conducted to evaluate the extent and duration of immediate postoperative coagulopathy after LDH. Materials and Methods: A retrospective analysis of perioperative record of LDH over three years was conducted after IRB approval. Variables such as age, gender, BMI, ASA classification, liver volume on CT scan, preoperative and postoperative INR, platelet count (PC and ALT of each donor for five days was noted. In addition, duration of surgery, remnant as percentage total liver volume (Remnant%, blood loss, day of peak in PC and INR were also noted. Coagulopathy was defined as being present if INR exceeded 1.5 or platelet count fell below 1 × 10 5 /mm 3 on any day. Data was analyzed using SPSS 20 for Windows. Between group comparison was made using the Student ′t′ test for continuous variables and chi square test for categorical variables. Univariate analysis was done. Multiple logistic regression analysis was used to find independent factor associated with coagulopathy. Results: Eighty four (84 donors had coagulopathy on second day (mean INR 1.9 ± 0.42. Low BMI, % of remnant liver and duration of surgery were independent predictors of coagulopathy. Right lobe hepatectomy had more coagulopathy than left lobe and low BMI was the only independent predictor. There was no correlation of coagulopathy with age, gender, blood loss, presence of epidural catheter, postoperative ALT or duration of hospital stay. High INR was the main contributor for coagulopathy. Conclusions: Coagulopathy is seen after donor hepatectomy. We recommend removal of the epidural catheter after the fifth postoperative day when INR falls below 1.5.

    Full Text Available In most sub-Saharan countries screening of blood-transmitted infections includes mainly HIV, HBV, HCV and syphilis. Many viruses such as Hepatitis G (HGV and Epstein-Barr virus (EBV which also carry a risk of transmission by blood transfusion raise the question of the extent of screening for these pathogens. This work aims to evaluate the prevalence of HGV and EBV in first-time blood donors in Ouagadougou. The prevalence of HGV and EBV in 551 blood donors was 7.4% and 5.4% respectively. HGV prevalence was significantly higher in blood donors with hepatitis B antigens and positive for HCV compared to donors negative for HCV and no hepatitis B antigens (respectively p<0.001 and p=0.004. EBV prevalence was higher among blood donors of < 20 years age group. This study shows significant results with regard to the prevalence of HGV and EBV prevalence in blood donors in Burkina Faso and emphasizes the need for a general screening.

    Despite a substantially lower rate of live donor kidney transplantation among Black Americans compared to White Americans, there are few systematic efforts to reduce this racial disparity. This paper describes the rationale and design of a randomized controlled trial aims evaluating the comparative effectiveness of three different educational interventions for increasing live donor kidney transplantation in Black Americans. This trial is a single-site, urn-randomized controlled trial with a planned enrollment of 180 Black Americans awaiting kidney transplantation. Patients are randomized to receive transplant education in one of three education conditions: through group education at their homes (e.g., House Calls), or through group (Group-Based) or individual education (Individual Counseling) in the transplant.. The primary outcome of the trial is the occurrence of a live donor kidney transplant, with secondary outcomes including living donor inquiries and evaluations as well as changes in patient live donor kidney transplantation readiness, willingness, knowledge, and concerns. Sex, gender, dialysis status, and quality of life are evaluated as moderating factors. Findings from this clinical trial have the potential to inform strategies for reducing racial disparities in live donor kidney transplantation. Similar trials have been developed recently to broaden the evaluation of House Calls as an innovative disparity-reducing intervention in kidney transplantation.

    Cyclosporine is often used to prevent allograft rejection in renal transplant recipients. However, cyclosporine has a narrow therapeutic window and large variability in its pharmacokinetics. Individual characteristics and genetic polymorphisms can cause the variation. Hence, it is important to determine the cause(s) of the variation in cyclosporine pharmacokinetics. To our knowledge, this is the first reported population pharmacokinetic study of cyclosporine in living donor renal transplant recipients that considered the genetic polymorphism as a covariate. To build a population pharmacokinetic model of cyclosporine in living donor renal transplant recipients and identify covariates including CYP3A5*3, ABCB1 genetic polymorphisms that affect cyclosporine pharmacokinetic parameters. Clinical characteristics and cyclosporine concentration data for 69 patients who received cyclosporine-based immunosuppressive therapy after living donor renal transplantation were collected retrospectively for up to 400 postoperative days. CYP3A5*1/*3 and ABCB1C1236T, G2677T/A, C3435T geno-typing was performed. A population pharmacokinetic analysis was conducted using a NONMEM program. After building the final model, 1000 bootstrappings were performed to validate the final model. In total, 2034 blood samples were collected. A 1-compartment open model with first-order absorption and elimination was chosen to describe the pharmacokinetics of cyclosporine. A population pharmacokinetic analysis showed that postoperative days, sex, and CYP3A5 genotype significantly affected the pharmacokinetics of cyclosporine. The final estimate of mean clearance was 56 L/h, and the mean volume of distribution was 4650 L. The interindividual variability for these parameters was 22.98% and 51.48%, respectively. Using the present model to calculate the dose of cyclosporine with CYP3A5 genotyping can be possible for the patients whose cyclosporine concentration is not within the therapeutic range even with

    Many have called for more comprehensive follow-up of living kidney donors, both for the donor's benefit and to establish a high-quality database of donor outcomes. United Network for Organ Sharing currently requires transplant centers to report donor follow-up information at several time points after donation, but little is known about how frequently this information is obtained, or which barriers exist to compliance with United Network for Organ Sharing requirements. To assess practices and barriers in providing follow-up care to living donors, we sent a questionnaire to all program directors at U.S. transplant centers. Few transplant centers are currently seeing donors for long-term follow-up. Many centers recommend that donor follow-up care be provided by primary care physicians, but follow-up information is rarely received from primary care physicians. The main barriers to collecting more complete information are donor inconvenience, costs, and lack of reimbursement to the transplant center for providing follow-up care. Significant changes are required to improve long-term donor follow-up by U.S. transplant centers.

    Previous reports have drawn attention to persistently decreased platelet counts among liver donors. We hypothesized an etiologic association between altered platelet counts and postdonation splenomegaly and sought to explore this relationship. This study analyzed de-identified computed tomography/magnetic resonance scans of 388 donors from 9 Adult-to-Adult Living Donor Liver Transplantation Cohort Study centers read at a central computational image analysis laboratory. Resulting liver and spleen volumes were correlated with time-matched clinical laboratory values. Predonation liver volumes varied 2-fold in healthy subjects, even when they were normalized by the body surface area (BSA; range = 522-1887 cc/m(2) , n = 346). At month 3 (M3), postdonation liver volumes were, on average, 79% of predonation volumes [interquartile range (IQR) = 73%-86%, n = 165] and approached 88% at year 1 (Y1; IQR = 80%-93%, n = 75). The mean spleen volume before donation was 245 cc (n = 346). Spleen volumes greater than 100% of the predonation volume occurred in 92% of donors at M3 (n = 165) and in 88% at Y1 after donation (n = 75). We sought to develop a standard spleen volume (SSV) model to predict normal spleen volumes in donors before donation and found that decreased platelet counts, a younger age, a higher predonation liver volume, higher hemoglobin levels, and a higher BSA predicted a larger spleen volume (n = 344, R(2)  = 0.52). When this was applied to postdonation values, some large volumes were underpredicted by the SSV model. Models developed on the basis of the reduced sample of postdonation volumes yielded smaller underpredictions. These findings confirm previous observations of thrombocytopenia being associated with splenomegaly after donation. The results of the SSV model suggest that the biology of this phenomenon is complex. This merits further long-term mechanistic studies of liver donors with an investigation of the role of

    Background Precise evaluation of the live donor's liver is the most important factor for the donor's safety and the recipient's prognosis in living donor liver transplantation (LDLT).Our study assessed the clinical value of computer-assisted three-dimensional quantitative assessment and a surgical planning tool for donor evaluation in LDLT.Methods Computer-assisted three-dimensional (3D) quantitative assessment was used to prospectively provide quantitative assessment of the graft volume for 123 consecutive donors of LDLT and its accuracy and efficiency were compared with that of the standard manual-traced method.A case of reduced monosegmental LDLT was also assessed and a surgical planning tool displayed the precise surgical plan to avoid large-for-size syndrome.Results There was no statistically significant difference between the detected graft volumes with computer-assisted 3D quantitative assessment and manual-traced approaches ((856.76±162.18) cm3 vs.(870.64±172.54) cm3,P=0.796).Estimated volumes by either method had good correlation with the actual graft weight (r-manual-traced method:0.921,r-3D quantitative assessment method:0.896,both P <0.001).However,the computer-assisted 3D quantitative assessment approach was significantly more efficient taking half the time of the manual-traced method ((16.91±1.375) minutes vs.(39.27±2.102) minutes,P <0.01) to estimate graft volume.We performed the reduced monosegmental LDLT,a pediatric case,with the surgical planning tool (188 g graft in the operation,which was estimated at 208 cm3 pre-operation).The recipient recovered without large-for-size syndrome.Conclusions Computer-assisted 3D quantitative assessment provided precise evaluation of the graft volume.It also assisted surgeons with a better understanding of the hepatic 3D anatomy and was useful for the individual surgical planning tool.

    Full Text Available Herein, we describe an extremely rare experience of a patient with liver cirrhosis from hepatitis C virus (LC-HCV who underwent an ABO-incompatible living donor liver transplantation (ABO-I-LDLT using a hepatitis B core antibody (HBc-Ab positive donor’s liver graft. A 47-year-old Japanese woman with end stage LC-HCV, as a recipient, was preoperatively administered rituximab, mycophenolate mofetil, and steroids without plasma exchange. A routine ABO-I-LDLT procedure was applied using her daughter’s HBc-Ab positive liver graft. Prophylaxis of the hepatitis B virus (HBV infection using hepatitis B immunoglobulin (HBIG and entecavir had been properly administered. Three months after the ABO-I-LDLT, HCV hepatitis relapsed. To date, this patient has been under antiviral therapy and prophylaxis of HBV infection using HBIG, while entecavir has been continued. The cognitions and techniques with regard to ABO-I-LDLT, prophylaxis of HBV cross infection, various patterns of immunosuppression, and antiviral therapy for HCV relapse are indispensable in managing a transplant recipient. According to the prophylaxis of HBV cross infection under ABO-I-LDLT, it may be very important to keep the HBs-Ab titer higher than usual for HBV naïve recipients, because severe systemic immunosuppression can cause de novo hepatitis.

    AIM: Autologous blood donation (ABD) is mainly used to reduce the use of banked blood. In fact, ABD can be regarded as acute blood loss. Would ABD 2-3 d before operation affect the CVP level and subsequently result in less blood loss during liver resection was to be determined.METHODS: Eighty-four patients undergoing living donor left hepatectomy were retrospectively divided as group Ⅰ (GⅠ)and group Ⅱ (GⅡ) according to have donated 250-300 mL blood 2-3 d before living donor hepatectomy or not. The changes of the intraoperative CVP, surgical blood loss,blood products used and the changes of perioperative hemoglobin (Hb) between groups were analyzed and compared by using Mann-Whitney Utest.RESULTS: The results show that the intraoperative CVP changes between GⅠ (n = 35) and GⅡ (n = 49) up to graft procurement were the same, subsequently the blood loss,but ABD resulted in significantly lower perioperative Hb levels in GⅠ.CONCLUSION: Since none of the patients required any blood products perioperatively, all the predonated bloods were discarded after the patients were discharged from the hospital, It indicates that ABD in current series had no any beneficial effects, in term of cost, lowering the CVP, blood loss and reduce the use of banked blood products, but resulted in significant lower Hb in perioperative period.

    Full Text Available The aim of the study was to detect if gadolinium-enhanced renal magnetic reso-nance angiography (MRA can replace conventional angiography in imaging vascular anatomy in potential living renal donors and compare with surgical findings. MR imaging (MRI and breath-hold three-dimensional gadolinium-enhanced MRA of kidneys were done for 60 conse-cutive patients for whom successful nephrectomy was done. MRA findings were compared with the findings of nephrectomy. MRI and MRA identified 28 out of 60 patients with normal arterial and venous anatomy, and concordance was found at surgery in 27 of these patients. Vascular anomalies were depicted on MRI in 32 patients, with concordance at surgery in 27 patients. Re-garding arterial anomalies, the MRA had a sensitivity of 89.3%, a specificity of 94.0% and an accuracy of 90.8%. For venous anomalies, the sensitivity was 98.5%, specificity was 100% and accuracy was 98.6%. In conclusion, gadolinium-enhanced MRA of the kidneys can replace con-ventional angiography as a safe and accurate modality for the assessment of potential living renal donors.

    We compared postoperative hepatic and renal functions and coagulation profiles in living donors undergoing right hepatectomy under isoflurane (n = 40) versus propofol (n = 40) anesthesia. After induction, anesthesia was maintained with isoflurane/air-O2 (group I) or propofol/air-O2 (group P) in addition to remifentanil and atracurium infusion in both groups. Aspartate aminotransferase, alanine aminotransferase, international normalized ratio (INR), activated partial thromboplastin time (aPTT), albumin, total bilirubin, blood urea nitrogen, creatinine, estimated glomerular filtration rate (GFR), platelet count, and hemoglobin levels were measured in the preoperative period, after end of the operation, and on the first, third, fifth and seventh postoperative days (PODs). INR was significantly increased on POD 3 and aPTT on POD 5 in group I compared with group P (P < .05). Albumin level was significantly lower in Group I on POD 1 and 3 (P < .05). GFR was significantly lower on POD 1 in the group I compared with group P (P < .05). The postoperative coagulation, GFR, and albumin values were superior following administration of propofol than isoflurane in donors who underwent living hepatectomy; however, both approaches were clinically safe, with no significant clinical difference.

    Renal transplantation in highly sensitized patients represents a major clinical challenge leading to long periods on the waiting list. When a living donor is available, the use of different strategies to desensitize recipients with preformed human leukocyte antigen antibodies can allow a successful transplantation. We performed a retrospective observational study including all living donor kidney transplantation (LDKT) with desensitization (DS) from 2008 to 2014 in our transplant unit. The rates of rejection and graft survival were evaluated. DS consisted of plasma exchange (PE), rituximab (RTX), and intravenous immunoglobulin (IVIG) induction with thymoglobulin and maintenance immunosuppression with tacrolimus, corticosteroids, and mycophenolate mofetil. From 2008 to 2014, we performed 368 LDKT, with 31 receiving desensitization. Seven cases from a clinical trial were excluded. Demographic data and outcomes were recorded. All of the patients received RTX + PE + IVIG. DS was performed for positive complement-dependent cytotoxicity cross-match (4.2%), T-cell- and/or B-cell-positive flow cytometry cross-match (87.5%) and presence of donor-specific antibodies alone (8.3%). We identified 23 episodes of rejection in 12 patients (50%); 79% were antibody-mediated rejections (AMR). Graft failure was 12.5%, with a mean time to graft loss of 229 ± 203 days. Mean follow-up was 37 ± 27 months, and graft survival was 91% and 86% at 1 and 5 years, respectively. Desensitization in LDKT appears to offer an acceptable option for highly sensitized patients. In our series, 41% presented an AMR and 12.5% showed transplant glomerulopathy in protocol and/or indication biopsies. However, short-term outcomes and graft survival were satisfactory.

    The incidence of morbidity and mortality after living donor liver transplantation (LDLT) is not well understood because reporting is not standardized and relies on single-center reports. Aborted hepatectomies (AHs) and potentially life-threatening near-miss events (during which a donor's life may be in danger but after which there are no long-term sequelae) are rarely reported. We conducted a worldwide survey of programs performing LDLT to determine the incidence of these events. A survey instrument was sent to 148 programs performing LDLT. The programs were asked to provide donor demographics, case volumes, and information about graft types, operative morbidity and mortality, near-miss events, and AHs. Seventy-one programs (48%), which performed donor hepatectomy 11,553 times and represented 21 countries, completed the survey. The average donor morbidity rate was 24%, with 5 donors (0.04%) requiring transplantation. The donor mortality rate was 0.2% (23/11,553), with the majority of deaths occurring within 60 days, and all but 4 deaths were related to the donation surgery. The incidences of near-miss events and AH were 1.1% and 1.2%, respectively. Program experience did not affect the incidence of donor morbidity or mortality, but near-miss events and AH were more likely in low-volume programs (≤50 LDLT procedures). In conclusion, it appears that independently of program experience, there is a consistent donor mortality rate of 0.2% associated with LDLT donor procedures, yet increased experience is associated with lower rates of AH and near-miss events. Potentially life-threatening near-miss events and AH are underappreciated complications that must be discussed as part of the informed consent process with any potential living liver donor.

Between 10/2004 and 9/2014, 911 donors having laparoscopic nephrectomy were surveyed 6 months post-donation. Surveys asked questions specific to their recovery experience, including time to return to normal activities and work and a description of their recovery time relative to pre-donation expectations. Of the 911, 646 (71%) responded: mean age at donation was 43.5±10.6 years; 65% were female, 95% were white, 51% were biologically related to their recipient, and 83% reported education beyond high school. Of the 646 respondents, a total of 35% returned to normal activities by 2 weeks post-donation; 79% by 4 weeks post-donation; 94% by 5-6 weeks; however, 6% took >6 weeks. Of the 646, 551 (85%) were working for pay; of these, mean time to return to work was 5.3±2.8 weeks; median, 5 weeks. Of the 551, a total of 14% returned to work in 1-2 weeks, 46% by 3-4 weeks, and 76% by 5-6 weeks. Importantly, 24% required >6 weeks before returning to work with the highest rates for donors in manual labor or a skilled trade. Significantly longer return to work was reported by females (vs males; P=.01), those without (vs those with) post-high school education (P=.010, those with longer hospital stay (P=.01), and those with a postoperative complication (P=.02). Of respondents, 37% described their recovery time as longer than expected. During the donor informed consent process, additional emphasis on realistic expectations around recovery to baseline activities and return to work is warranted.

    We investigate time-dependent electron transfer (ET) in benchmark donor-bridge-acceptor systems. For the small bridge sizes studied, we obtain results far different from the perturbation theory which underlies scattering-based approaches, notably a lack of destructive interference in the ET for certain arrangements of bridge molecules. We also calculate wavepacket transmission in the non-steady-state regime, finding a featureless spectrum, while for the current we find two types of transmission: sequential and direct, where in the latter, the current transmission increases as a function of the energy of the transferred electron, a regime inaccessible by conventional scattering theory.

    The practice of living donor liver transplantation (LDLT) has been increasing over the past 20 years. In LDLT, a healthy individual offers a substantial part of his or her liver (up to 60%) for the benefit of a terminally-ill recipient. The aim of the study was to identify decision-making and risk-assessment patterns of living liver donors and assess whether the principles of informed consent and decision autonomy are being met. The authors conducted semistructured clinical interviews with 28 donors before transplantation. The authors found that a decision was being reached before a decision-making process could take place. Surgery risks were perceived and processed in different ways, including the factors of risk-awareness, denial, limited acceptance, and fatalism. The authors assess concepts of informed consent and decision autonomy in LDLT, and offer suggestions for donor selection.

    Background Live donor kidney transplantation (LDKT), an optimal therapy for many patients with end-stage kidney disease, is underutilized, particularly by African Americans. Potential recipient difficulties initiating and sustaining conversations about LDKT, identifying willing and medically eligible donors, and potential donors’ logistical and financial hurdles have been cited as potential contributors to race disparities in LDKT. Few interventions specifically targeting these factors have b...

    Abstract Donor nephrectomy in living-donor kidney transplantation may result in hyperfiltration injury in remnant kidney; however, its clinical implication in partial recovery of kidney function (PRKF) in remnant kidney and chronic kidney disease (CKD) progression remains unclear. Thus, we investigated the effect of PRKF on CKD development in the residual kidney and the utility of cystatin-C (Cys-C) in evaluating renal function in living-donor kidney transplantation donors. The electronic medical records and laboratory results of 1648 kidney transplant (KT) donors and 13,834 healthy nondonors between January 2006 and November 2014 were reviewed. The predictors of PRKF and CKD diagnosed by Kidney Disease: Improving Global Outcomes (KDIGO) criteria were evaluated by multivariate analysis. CKD risk was compared between KT donors and healthy nondonors using Cox proportional hazard regression analysis following propensity score matching (PSM). The incidence of PRKF for KT donors was 49.3% (813). CKD incidence was 24.8% (408) in KT donors and 2.0% (277) in healthy nondonors. The predictors of PRKF were, male sex (odds ratio [OR], 17.32; 95% confidence interval [CI] 9.16–32.77), age (OR, 1.02; 95% CI, 1.00–1.04; P PSM, the risk of progression to CKD was higher in KT donors than in healthy nondonors (HR, 58.4; 95% CI, 34.2–99.8; P < 0.001). Donor nephrectomy is associated with PRKF and progression to CKD. Cys-C is a useful early marker for detecting PRKF and CKD. PMID:28151912

    Summary Choice of an appropriate anaesthetic technique and adequate pain relief during laparoscopic living donor nephrectomy (LDN) is likely to make the procedure more appealing to kidney donors. Various analgesic regimens proposed to relieve pain after laparoscopic surgery include: opioids, non-opioid analgesics followed by opioids for the breakthrough pain and intra-peritoneal normal saline irrigation and instillation of local anaesthetics at surgical sites. Thorough literature review and medline search did not reveal any study where a combination of orogastric acetazolamide along with intraperitoneal saline irrigation and bupivacaine instillation techniques have been tried in these patients. In a prospective, double blind, randomized trial, eighty healthy adults undergoing LDN under general anaesthesia were enrolled to compare the efficacy of an acetazolamide based multimodal analgesic approach (Group A) with conventional pain management (Group B). Donors' demographics, intra-operative variables, early allograft function and recovery characteristics were evaluated for 72 hours. The primary end points were postoperative pain intensity on a visual analog scale and the incidence of shoulder tip pain (STP). The secondary end points included the latency of the rescue analgesia request rate, total analgesic consumption and patient satisfaction. Consistently lower mean pain scores were observed in Group A (p<0.03 for visceral pain). Frequency as well as the total dose of rescue analgesics administered was significantly less in Group A (p=0.001). Twelve patients (30.7%) in Group B complained of STP compared to three (7.5%) in Group A (p=0.025). Shoulder pain also presented earlier (8 hours versus 12 hours) and persisted for longer period in Group B (72 hours versus 48 hours, p 0.025). To conclude, a multimodal analgesic approach consisting a combination of orogastric acetazolamide, intraperito-neal saline irrigation and use of bupivacaine in the operated renal fossa

    2011-02-01

    Ever since the start of the twentieth century, a growing interest and importance of studying fatwas can be noted, with a focus on Arabic printed fatwas (Wokoeck 2009). The scholarly study of end-of-life ethics in these fatwas is a very recent feature, taking a first start in the 1980s (Anees 1984; Rispler-Chaim 1993). Since the past two decades, we have witnessed the emergence of a multitude of English fatwas that can easily be consulted through the Internet ('e-fatwas'), providing Muslims worldwide with a form of Islamic normative guidance on a huge variety of topics. Although English online fatwas do provide guidance for Muslims and Muslim minorities worldwide on a myriad of topics including end-of-life issues, they have hardly been studied. This study analyses Islamic views on (non-)voluntary euthanasia and assisted suicide as expressed in English Sunni fatwas published on independent--i.e. not created by established organisations--Islamic websites. We use Tyan's definition of a fatwa to distinguish between fatwas and other types of texts offering Islamic guidance through the Internet. The study of e-fatwas is framed in the context of Bunt's typology of Cyber Islamic Environments (Bunt 2009) and in the framework of Roy's view on the virtual umma (Roy 2002). '(Non-)voluntary euthanasia and assisted suicide' are defined using Broeckaert's conceptual framework on treatment decisions at the end of life (Broeckaert 2008). We analysed 32 English Sunni e-fatwas. All of the e-fatwas discussed here firmly speak out against every form of active termination of life. They often bear the same structure, basing themselves solely on Quranic verses and prophetic traditions, leaving aside classical jurisprudential discussions on the subject. In this respect they share the characteristics central in Roy's typology of the fatwa in the virtual umma. On the level of content, they are in line with the international literature on Islamic end-of-life ethics. English Sunni e-fatwas make

    Biliary leakage is a major complication after hepatectomy. We report the case of a living-donor liver transplantation (LDLT) donor with a late-onset bile leak from the trifurcation of the hepatic duct who was successfully treated using rendezvous technique. A 52-year-old man underwent extended left hepatectomy for donation and was discharged on postoperative day (PD) 13. However, he was rehospitalized on PD 26 with severe abdominal pain. Physical examination suggested panperitonitis, and abdominocentesis showed bilious ascites. Emergent laparotomy for biliary leakage and peritonitis was performed. There was bilious ascites in the peritoneal cavity. A biliary fistula was recognized at the trifurcation of B8a, B8b, and B5. Intraoperative transhepatic biliary drainage of each bile duct was performed. Endoscopic transpapillary drainage was performed on PD 24. Finally, external drains were removed and complete internal drainage established on PD 70. The bile leak was considered to be the result of injury from electrocautery device. Appropriate making choices of the electrocautery devices enable us to avoid over thermal injury of the liver surface. Rendezvous bidirectional drainage effectively treated late-onset bile leakage from the trifurcation of a hepatic bile duct.

    In spite of many improvements that have reduced the blood component requirements, substantial numbers of transfusions are still needed in liver transplantation. The objective of the present study was to analyze the perioperative usage of allogenic blood components and predict the preoperative factors as predictors of red cell transfusion in live-related donor liver transplant recipients. The retrospective data on utilization of allogenic blood components were analyzed for a total of 150 liver transplant procedures. The data on utilization of blood components during surgery and till 48 hours of ICU stay was collected from the blood bank record and hospital information system (HIS). Red cell concentrate was commonest blood component used in liver transplant recipient and most of the transfusion took place during surgery. During intraoperative period 92.7% (N = 139) of the cases utilized red cell components with the median number of five whereas in postoperative period only 38% (N = 57) of patients received blood with the median number of one. This study demonstrates that the preoperative hemoglobin and platelet count are the predictors of utilization of red cell concentrates during surgery. There were a total of 11 (7.3%) recipients who didn't receive allogeneic blood transfusion in any form. Utilization of blood components was negligible among organ donors. Our study demonstrates the pattern and predictors of usage of allogeneic blood components in liver transplant recipients at a tertiary healthcare center in India.

    Our results concur with earlier published work, by other groups, showing that LRD-recipient pairs with low MLC stimulation usually have better and more prolonged graft success than do those with higher stimulation. Specific HL-A compatibilities or incompatibilities did not seem to affect these results, nor did the presence of an increased number of common loci, short of increasing the apparent chromosome compatibility. The presence of pre-transplant cytotoxic antibodies, in patients with a high MI, however, may unfavorably affect the LRD transplant. The overall results of our LRD transplant experience is shown in Figure 1, and superimposed upon Figure 2, is the current extrapolation of data showing MLC stimulation and haplotype success. Thus, it appears that graft survival may be improved and more closely approach the levels seen in a full-house, diplotype match, by using the MLC results in considering patients for transplantation. Not all patients with a high MLC, however, (see table) reject their grafts and it is impossible to predict pre-transplant who will develop specific allograft enhancement. Before the MI becomes a specific criteria for transplant selection, additional studies of patient stimulation in MLC should be done. Suppression of stimulation by donor cells in autologous serum, as compared to the response to unrelated controls, might provide pre-transplant clues to the presence of enhancing factors. Such studies could provide an index that would be more meaningful than the MI in AB sera alone. Since overall results from both our series and from the Transplant Registry continue to indicate better long term graft survival for LRD than for cadaver transplants, and since the evidence suggests that a successful transplant offers a patient a better quality of life, as well as decreased morbidity and mortality compared to concomitant time spent on hemodialysis, continued LRD transplants with high MI is warranted in some circumstances with the patient

    To assess the clinical efficacy of alternative techniques for biliary stricture cannulation in patients undergoing living donor liver transplantation (LDLT), after cannulation failure with a conventional (0.035-inch guidewire) technique. Of 293 patients with biliary strictures after LDLT, 19 (6%) patients, 11 men and 8 women of mean age 48.5 years, had the failed cannulation of the stricture by conventional techniques. Recannulation was attempted by using two alternative methods, namely a micro-catheter set via percutaneous access and a snare (rendezvous) technique using percutaneous and endoscopic approaches. Strictures were successfully cannulated in 16 (84%) of the 19 patients. A microcatheter set was used in 12 and a snare technique in four patients. Stricture cannulation failed in the remaining three patients, who finally underwent surgical revision. Most technical failures using a conventional technique for biliary stricture cannulation after LDLT can be overcome by using a microcatheter set or a snare (rendezvous) technique.

    Biliary anastomosis stricture (BAS) is still among the major concerns after living donor liver transplantation (LDLT), even after the technical refinements including the universal use of the blood flow-preserving hilar dissection technique. The aim of this study is to investigate what are still the factors for BAS after LDLT. An analysis of 279 adult-to-adult LDLT grafts (left lobe, n = 161; right lobe, n = 118) with duct-to-duct biliary reconstruction, since the universal application of minimal hilar dissection technique and gradual introduction of eversion technique, was performed. There were 39 patients with BAS. Univariate analysis showed that a right lobe graft (P = 0.008), multiple bile ducts (P dissection technique could be a key for preventing BAS in duct-to-duct biliary reconstruction in LDLT.

    We show that HIV-infected waitlisted patients (n=33) had significantly lower knowledge (P<0.001), more concerns (P=0.01), and lower willingness to pursue live-donor kidney transplantation (LDKT; P=0.02) than matched noninfected patients. The majority (78%) of patients felt that their HIV status reduced their chance of LDKT. Although limited to a single center and a small sample, our data suggest that HIV-infected patients who are waitlisted for kidney transplantation may need more education about the potential benefits of LDKT and may benefit from patient-centered decision support to facilitate a risk-benefit assessment consistent with their preferences and values.

    The aim of this paper is to report the authors'experience in performing adult-to-adult living donor liver transplantation (LDLT)by using a modified technique in using grafts of the right lobe of the liver.From January 2002 to September 2006,56 adult patients underwent LDLT using right lobe grafts at the Wlest China Hospital.Sichuan University Medical School,China.All patients underwent a modified operation designed to improve the reconstruction of the right hepatic vein (RHV)and the tributariers of the middle hepatic vein(MHV)by interposing a vessel graft,and by anastomosing the hepatic arteries and bile ducts.There were no severe complications or deaths in all donors.Fifty-two (92.8%) recipients survived the operations.Among the 56 recipients,complications were seen in 15 recipients(26.8%),including hepatic vein stricture(one case),small-for-size syndrome(one case),hepatic artery thrombosis(two cases),intestinal bleeding (one case),bile leakage(two cases),left subphrenic abscess (one case),renal failure(two cases)and pulmonary infection (five cases).Within three months after transplantation,four recipients(7.1 4%)died due to smallfor-size syndrome(one case),renal failure(one case)and multiple organ failure(two cases).All patients underwent direct anastomoses of the RHV and the inferior vena cava (IVC),and in 23 cases,reconstruction of the right inferior hepatic vein was also done.In 24 patients,the reconstruction of the tributaries of the MHV was also done by interposing a vessel graft to provide sufficient venous outflow.Trifurcation of the portal vein was seen in nine cases.Thus,veno-plasty or separate anastomoses were performed.The graft and recipient body weight ratios(GRWR)were between 0.72%and 1.43%,and in three cases it was<0.8%.The graft weight to recipient standard liver volume ratios (GV/SLV) were between 31.86%and 71.68%.among which four cases had<40%.No "small-for-size syndrome"occurred.With modification of the surgical technique,especially in the

    Full Text Available Chronic allograft nephropathy (CAN remains a major cause of graft failure over the long term, second only to patient mortality. The main adverse effects of cyclosporine A (CsA include nephrotoxicity, hypertension, symptomatic hyperuricemia, hirsutism, and gum hyperplasia. Available studies among live related donor renal transplants lack adequate information regarding the long-term efficacy and safety of primary CsA-based immunosuppressive regimens. This prospective randomized study is aimed at evaluating the long-term results of CsA-based immunosuppressive protocols in live-donor kidney transplantation. The follow-up data of 444 renal transplant recipients operated at the Urology and Nephrology Center, Mansoura University, prior to 1996 were reviewed. Primary immuno-suppressive protocols included: steroids and azathioprine (group I, 130 cases; steroids and CsA (group II, 75 cases; and steroids, CsA, and azathioprine (group III, 239 cases. Only adult primary renal transplant recipients with age ranging between 18 and 60 years and one haplotype HLA mismatch with the donor were included. All patients received kidneys from living related donors with previous donor non-specific blood transfusions. The percentage of cases with chronic rejection was significantly higher in group III. Living cases with graft failure were significantly higher in group III, whereas mortality was significantly higher in group I. Diabetic patients and those with serious bacterial infections were significantly more prevalent in group II. Hypertensive patients were significantly more common in groups I and II. Liver disease was more prevalent among patients in group III. Our study suggests that the long-term results of treatment with steroids and azathioprine are satisfactory in live related donor kidney transplant recipients. Chronic rejection was significantly higher in patients in group III, possibly due to the risk of CsA nephrotoxicity. Groups with CsA-based protocols

    In the latter part of 2009, the Department of Health of the Philippines prohibited kidney transplantation with non-related kidney donors. Hence, the National Kidney and Transplant Institute created a Hospital Transplant Ethics Committee. This study describes directed non-related kidney donation at the National Kidney and Transplant Institute. This retrospective study reviewed the profiles of recipients and directed living non-related kidney transplant donors submitted to the Hospital Transplant Ethics Committee. A total 74 recipients and donors were reviewed by the Hospital Transplant Ethics Committee in 2014. Donors initiated the talks about being a donor (75%) to repay the good deeds that were done by the recipient for them or their families; examples of which are: sometime in their lives they needed financial assistance for hospitalization for their relatives and it was the patient who paid the hospital bill; or because they pitied the recipient, whom they found to be a good person, thus they would want to give one of their kidneys. Seventy-four (100%) said that they were not expecting anything in return for this act but wanted to be of help to the recipient. Of these 74 cases, 70 cases (95%) were approved and the others were disapproved. With a Hospital Transplant Ethics Committee in place, directed kidney donation is a valuable tool as an additional source of kidney donor without violating any ethical issues. Copyright © 2016.

    Objective To conduct an epidemiological analysis on the main microbiological markers in bone tissue that was processed at the musculoskeletal tissue bank of Hospital São Vicente de Paulo, in Passo Fundo, between August 2007 and October 2011. Methods Between August 2007 and October 2011, 202 musculoskeletal tissue samples were collected for the tissue bank. Among these, 159 samples were from living donor patients and 43 were from cadaver donors. The following serological tests were requested: hepatitis B, hepatitis C, syphilis, cytomegalovirus, Chagas disease, toxoplasmosis, HIV and HTLV. Results Among the 159 living donors, 103 (64.75%) were men and 56 (35.25%) were women. The patients’ mean age was 59.35 ± 8.87 years. Out of this total, 76 tissue samples (47.8%) from donors were rejected. There was no difference in the number of rejections in relation to sex (p = 0.135) or age (p = 0.523). The main cause of rejection was serologically positive findings for the hepatitis B virus, which was responsible for 48 rejections (63.15%). Among the 43 cadaver donors, the mean age was 37.84 ± 10.32 years. Of these, 27 (62.8%) were men and 16 (37.2%) were women. Six of the samples collected from cadaver donors were rejected (13.9%), and the main cause of rejection was serologically positive findings for the hepatitis C virus, which was responsible for three cases (50%). There was no significant difference in the number of rejections in relation to sex (p = 0.21) or age (p = 0.252). Conclusion There were a greater number of rejections of tissues from living donors (47.8%) than from cadaver donors (13.9%). Among the living donors, the main cause of rejection was the presence of serologically positive findings of the hepatitis B virus, while among the cadaver donors, it was due to the hepatitis C virus.

    Kenya is one of the high endemic zones for hepatitis B virus (HBV) infection. The consensuses on prevalence of the HBV genotypes and the existence of their variants have not been fully established in Kenya. Hence, there is a need to further monitor the diversity of HBV. This study aimed to extend the current molecular and epidemiological information about the geographical distribution of HBV genotypes and subgenotypes, as well as to describe the hepatitis B surface antigen (HBsAg) variants circulating in different Regional Blood Transfusion Centres of Kenya. A total of 32 HBsAg positive blood units from five different blood transfusion centers in Kenya were used in the study. The HBV DNA preS/S-gene was amplified and sequenced. Alignments of S gene were applied using reference sequence from GeneBank. Phylogenetic analysis was performed using the MEGAv4.0 software with the neighbor-joining and maximum composite likelihood methods. Twenty-one plasma samples (65.6%) were DNA positive and were successfully sequenced. Eighteen out of the twenty-one isolates (85.7%) belonged to subgenotype A1 Afro-Asian: six were from Nairobi, four from Kisumu, two from Embu, and three each from Eldoret and Mombasa. The other three strains (14.3%, 3/21) belonged to subgenotype D4 from Mombasa. The HBsAg mutations were detected in nine isolates (42.9%, 9/21). The HBV/A1 and HBV/D4 are dominant among blood donors in Kenya. This demonstrates that continuous monitoring of the HBV diversity would help reveal circulating genotypes and subgenotypes as well as mutants of clinical significance in Kenya.

    Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). The evaluation process for a kidney transplant is complex, time consuming, and burdensome to the ESKD patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. In December 2012 our transplant center implemented a streamlined, one-day evaluation process, dubbed Kidney Transplant Fast Track (KTFT). This paper describes the protocol of a two-part study to evaluate the effectiveness of KTFT at increasing transplant rates (compared to historical controls) and the TALK intervention (Talking About Live Kidney Donation) at increasing LDKT during KTFT. All participants will receive the KTFT evaluation as part of their usual care. Participants will be randomly assigned to TALK versus no-TALK conditions. Patients will undergo interviews at pre-transplant work-up and transplant evaluation. Transplant status will be tracked via medical records. Our aims are to: (1) test the efficacy and cost effectiveness of the KTFT in reducing time to complete kidney transplant evaluation, and increasing kidney transplant rates relative to standard evaluation practices; (2) test whether TALK increases rates of LDKT during KTFT; and (3) determine whether engaging in a streamlined and coordinated-care evaluation experience within the transplant center reduces negative perceptions of the healthcare system. The results of this two-pronged approach will help pave the way for other transplant centers to implement a fast-track system at their sites, improve quality of care by transplanting a larger number of vulnerable patients, and address stark race/ethnic disparities in rates of LDKT.

    Nonalcoholic steatohepatitis (NASH) is a stage of nonalcoholic fatty liver disease (NAFLD), and, in most patients, it is associated with obesity and metabolic syndrome with progression to end-stage liver disease in about 20% of patients (McCullough (2004); Matteoni et al. (1999); Liou and Kowdley (2006)). It has been estimated that between 20 and 30% of patients with end-stage cirrhosis referred for liver transplantation (LT) evaluation and 30 to 70% of LT recipients exhibit some degree of obesity (Muñoz and ElGenaidi (2005)). Management of obesity in chronic liver disease patients is not only difficult but also preludes them from undergoing major bariatric surgery due to associated high morbidity and mortality. Here, we present a case report of a morbidly obese patient who underwent laparoscopic sleeve gastrectomy followed by single-lobe living donor liver transplantation (LDLT) with a successful outcome. We believe that this is the first report of successful LDLT following planned weight loss to facilitate LDLT. PMID:24386588

    Background Percutaneous biopsy is a widely-accepted technique for acquiring histologic samples of the liver. When there is concern for bleeding, plugged percutaneous biopsy (PPB) may be performed, which involves embolization of the biopsy tract. Purpose To evaluate the efficacy and safety of PPB of the liver in patients suspected to have graft rejection after living-donor liver transplantation (LDLT). Material and Methods During January 2007 and December 2013, 51 patients who underwent PPB of the liver under the suspicion of post-LDLT graft rejection were retrospectively analyzed. A total of 73 biopsies were performed. Biopsy was performed with a 17-gauge core needle and 18-gauge cutting needle. The needle tract was embolized using gelatin sponge (n = 44) or N-butyl cyanoacrylate (NBCA) (n = 29). The specimens were reviewed to determine their adequacy for histologic diagnosis. We reviewed all medical records after PPB. Results Specimens were successfully acquired in all procedures (100%). They were adequate for diagnosis in 70 cases (95.9%) and inadequate in three (1.3%). Average of 9.8 complete portal tracts was counted per specimen. One minor complication (1.4%) occurred where the patient had transient fever after the procedure. Conclusion PPB is easy and safe to perform in LDLT recipients and provides high diagnostic yield.

    We performed living donor liver transplantation (LDLT) in a patient who had undergone distal gastrectomy for gastric ulcer disease with Billroth I reconstruction 30 years before the LDLT. The adhesion was very severe between remnant stomach and hepatic hilum as well as left liver lobe with shortening of hepatoduodenal structures. After dissection of the infrahepatic inferior vena cava, the Spiegel lobe was identified from the dorsal side. The Spiegel lobe was then penetrated with a right angle dissector so that a plastic tape could be placed around the whole adhesion, including important structures in the hepatoduodenal ligament. Next, the right hepatic vein was transected with a vascular stapler using Pringle's maneuver using the plastic tape to fasten the entire adhesional structure. Subsequently, the trunk of the middle and left hepatic vein was transected after clamping. The remaining short hepatic veins in the left side were divided completely from the cranial to the caudal direction to dissect Spiegel's lobe. Finally, the hepatoduodenal ligament was identified from the attached remnant stomach and the duodenum and a vascular clamp was placed on the entire hepatoduaodenal ligament. Finally, the diseased liver was explanted for graft implantation. Thus, retrograde explantation of the liver was effective in decreasing the risk of damaging vital elements in the hepatoduodenal ligament, the remnant stomach, and the duodenum.

    After living donor liver transplantation (LDLT), the prevalence of complications related to the biliary system is 6-35%. In spite of great improvements in both surgical techniques and postoperative and long-term medical treatment, the biliary complications are still considered a relatively high risk for LDLT. The aim of this retrospective study was to analyze the incidence of biliary complications and identify predisposing risk factors. The clinical and follow-up data of 175 adult patients receiving LDLT (right lobe or left lobe) between 2002 and December 2008 were collected and retrospectively analyzed. Patients were divided into 2 groups: with biliary complications (n=30) and without biliary complications (n=145). Thirty patients (17.1%) had post-transplantation biliary complications. Eight patients (4.6%) were diagnosed with bile leakage, while 24 patients (13.7%) developed biliary stricture. Percentage of steatosis of the graft and hepatic artery thrombosis after LDLT were two factors upon univariate analysis (p=0.034, p=0.01, respectively). In multivariate logistic analysis, 20-50% macrovesicular steatosis emerged as a new defined risk factor by us (p=0.001). There was no difference in patient survival rate in different groups and sorts of graft steatosis (p>0.05). We consider that using a graft with macro-vesicular steatosis in 20-50% should be put on the table carefully, balancing both sides of positive and negative.

    Middle hepatic vein (MHV) reconstruction is often essential to avoid hepatic congestion and serious graft dysfunction in living donor liver transplantation (LDLT). The aim of this report was to introduce evolution of our MHV reconstruction technique and excellent outcomes of simplified one-orifice venoplasty. We compared clinical outcomes with two reconstruction techniques through retrospective review of 95 recipients who underwent LDLT using right lobe grafts at our institution from January 2008 to April 2012; group 1 received separate outflow reconstruction and group 2 received new one-orifice technique. The early patency rates of MHV in group 2 were higher than those in group 1; 98.4% vs. 88.2% on postoperative day 7 (p = 0.054) and 96.7% vs. 82.4% on postoperative day 14, respectively (p = 0.023). Right hepatic vein (RHV) stenosis developed in three cases in group 1, but no RHV stenosis developed because we adopted one-orifice technique (p = 0.043). The levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in group 2 were significantly lower than those in group 1 during the early post-transplant period. In conclusion, our simplified one-orifice venoplasty technique could secure venous outflow and improve graft function during right lobe LDLT.

    AIM: To investigate thrombotic microangiopathy (TMA) in liver transplantion, because TMA is an infrequent but life-threatening complication in the transplantation field.METHODS: A total of 206 patients who underwent living-donor liver transplantation (LDLT) were evaluated, and the TMA-like disorder (TMALD) occurred in seven recipients.RESULTS: These TMALD recipients showed poor outcomes in comparison with other 199 recipients.Although two TMALD recipients successfully recovered, the other five recipients finally died despite intensive treatments including repeated plasma exchange (PE) and re-transplantation.Histopathological analysis of liver biopsies after LDLT revealed obvious differences according to the outcomes.Qualitative analysis of antibodies against a disintegrin-like domain and metalloproteinase with thrombospondin type 1 motifs (ADAMTS-13) were negative in all patients.The fragmentation of red cells, the microhemorrhagic macules and the platelet counts were early markers for the suspicion of TMALD after LDLT.Although the absolute values of von Willebrand factor (vWF) and ADAMTS-13 did not necessarily reflect TMALD, the vWF/ADAMTS-13 ratio had a clear diagnostic value in all cases.The establishment of adequate treatments for TMALD, such as PE for ADAMTS-13 replenishment or treatments against inhibitory antibodies, must be decided according to each case.CONCLUSION: The optimal induction of adequate therapies based on early recognition of TMALD by the reliable markers may confer a large advantage for TMALD after LDLT.

    There are few reports on the short- and long-term follow-up of endoscopic retrograde cholangiography (ERC) in adult patients with hepaticojejunostomy (HJS) stricture after living-donor liver transplantation (LDLT). Nine LDLT recipients underwent ERC with the use of double-balloon endoscopy (DBE) for HJS stricture at Nagoya University Hospital. We assessed the rate of reaching biliary anastomosis, procedure success rate, procedure duration, complications, improvement in liver function test results, and biliary anastomosis patency. In total, 19 ERC procedures with the use of DBE were performed for 9 adult LDLT recipients with HJS stricture from June 2006 to September 2014. Balloon dilation with the use of DBE was successfully performed in 5 of the 9 patients during the 1st procedure. Of the 4 patients in whom DBE-ERC failed to be completed, 3 patients underwent 2nd procedures successfully. Liver function test results were significantly improved in the successful cases. Four patients underwent 2nd DBE-ERC for stricture recurrence at a mean time of 2.3 years after the 1st successful procedure. Of those, 2 patients required 3rd procedures for stricture recurrence after the 2nd procedure. DBE-ERC is promising as a treatment for HJS stricture in adult LDLT recipients in the short term. However, the DBE-ERC procedure may have a considerable risk of restenosis. Copyright © 2015 Elsevier Inc. All rights reserved.

    Despite the development of strategies to minimize blood loss during hepatectomy challenges remain. Our aim was to determine whether low positive airway pressure (PAP) without positive end-expiratory pressure (PEEP) could minimize blood loss during hepatectomy. Forty-one living liver donors who underwent extended left lobectomy or right lobectomy between December 2012 and November 2013 were retrospectively analyzed. In the standard PAP group (n = 18), tidal volume was 8-10 ml/kg, respiratory rate was 10-12/min and PEEP was maintained at 5 cm H2O. In the low PAP group (n = 23), tidal volume was reduced to 5 ml/kg, respiratory rate was increased to 15/min and PEEP maintained at 0 cm H2O. Low central venous pressure (CVP) was maintained during surgery in all cases. The low PAP group had significantly less blood loss (p = 0.0075) and shorter operation time (p = 0.0303) than the standard PAP group. In multiple regression analysis, ventilation mode and median CVP were found to be determining factors for blood loss. In no case did the ventilation mode affect perioperative management. Low PAP without PEEP is a safe mechanical ventilation mode that might help minimize blood loss along with CVP monitoring during hepatectomy. © 2016 S. Karger AG, Basel.

    BACKGROUND: Although perioperative portal vein (PV) stent implantation is an effective treatment for steno-occlusive disease in adult living donor liver transplantation (LDLT) re-cipients, we experienced high incidence of biliary anastomotic strictures (BAS) after PV stenting. In this study, we sought to clarify the relation between BAS and PV stenting and to suggest the possible mechanism of BAS and measures to reduce its in-cidence. METHODS: We retrospectively analyzed 44 LDLT recipients who underwent PV stent implantation across the line of PV anastomosis regardless of the location of steno-occlusion (stent group) and their matched controls (non-stented LDLT recipients, n=131). RESULTS: The incidence of BAS was higher in patients in the stent group than that in the control group (43.2% vs 17.6%, P=0.001). Cumulative 6-month and 1-, 2- and 5-year BAS rates were 31.8%, 34.1%, 41.4% and 43.2%, respectively, in the stent group and 13.0%, 13.8%, 16.1% and 17.8%, respectively, in the control group (P=0.001). Multivariate analysis revealed that PV stenting was an independent risk factor for BAS. CONCLUSIONS: Although PV stent implantation is a reliable treatment modality for steno-occlusive PV in adult LDLT recipients, innovative methods to prevent the PV stent from crossing the line of PV anastomosis may be necessary to reduce the incidence of postoperative BAS.

    Recurrence of primary biliary cirrhosis (PBC) after liver transplantation has been shown to negatively affect graft and patient survival. Recently, protective effects of cyclosporine A against PBC recurrence after liver transplantation have been reported. Participants were 4 patients who underwent living-donor liver transplantation (LDLT) for end-stage liver disease due to PBC. Tacrolimus was used for initial immunosuppression, and this was switched to cyclosporine A at least 3 months after liver transplantation. Targeted trough level of cyclosporine A was 20 times that of tacrolimus. We assessed liver and renal function, as well as antimitochondrial M2 antibody for recipients prior to LDLT, as well as before and after switching immunosuppressive agents. Patients were 1 man and 3 women, and they were ages 45 to 47 years at LDLT. Timing of switching from tacrolimus to cyclosporine A was 13, 3, 7, and 4 months respectively after liver transplantation, and all 4 patients have been on cyclosporine A without adverse effects at 20 to 46 months after transplantation. In 2 of 4 patients who had high titers of antimitochondrial M2 antibody before transplantation, antibody titer did not elevate after LDLT. In the other 2 patients without elevation of antimitochondrial M2 antibody, the titer did not turn positive. Switching from tacrolimus to cyclosporine A was possible without medical problems, and all patients exhibit no recurrence of PBC. Cyclosporine A may be useful for prevention of PBC recurrence after LDLT.

    The aim of this study was to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and catheter maintenance (BDCM) method for postoperative biliary strictures following living donor liver transplantation (LDLT). Eighteen patients (14 duct-to-duct anastomosis and 4 hepaticojejunostomy) with post-LDLT biliary stricture were treated by the percutaneous BDCM method. A good response was defined as residual stricture over 3.5 mm after repetitive BDCM and refractory response as residual stricture below 3.5 mm. If they demonstrated good results on follow-up studies after catheter withdrawal, all the patients quit the therapy. We evaluated the technical and clinical success rates, major complication rate, mean total procedure time and mean follow-up duration. The percutaneous BDCM method was technically successful without major complication. Nine patients improved biliary stricture (good response, mean 5.5 mm), and the other 9 patients showed residual stricture with the diameter below 3.5 mm (refractory response, mean 2.5 mm). However, all the patients were improved clinically without significant complication. The total procedure time was 1-15 months (mean 7.3 months) and follow-up duration was 6-54 months (mean 24 months). The percutaneous BDCM method for post-LDLT biliary strictures was an effective therapy even in the patients showing a refractory response. It seemed that total procedure time could be reduced if the response was determined earlier.

    Blood group incompatibility in kidney transplants from a living donor can be successfully overcome by using various desensitization protocols: intravenous immunoglobulin, plasmapheresis (PP), immunoadsorption, and double filtration PP. From July 2010 to October 2013, we performed 10 ABO incompatible kidney transplantation (KT) procedures from a living donor. The desensitization protocol was based on rituximab and PP+cytomegalovirus immune globulin. All patients received induction with basiliximab, except 1 case treated with Thymoglobuline® (ATG) for the simultaneous presence of donor-specific antibody. Tacrolimus and mycophenolate mofetil were initiated at the time of desensitization and continued after the transplant. After a mean follow-up of 11.6±10.4 months, all patients are alive with a functioning graft. The mean serum creatinine concentration at 1 month, 3 months, 6 months, and 1 year was 1.48±0.29, 1.47±0.18, 1.47±0.27, and 1.5±0.27 mg/dl. Three episodes of acute cellular rejection occurred in 2 patients. There was only 1 case of BK virus infection, treated with reduction of immunosuppressive therapy. The protocol biopsy specimens at 1, 3, and 6 months were C4d positive in the absence of acute rejection. Desensitization with rituximab, PP, and anti-cytomegalovirus immune globulin allowed us to perform transplants from living donors to ABO incompatible recipients with excellent results and reduced costs.

    Donor nephrectomy in living-donor kidney transplantation may result in hyperfiltration injury in remnant kidney; however, its clinical implication in partial recovery of kidney function (PRKF) in remnant kidney and chronic kidney disease (CKD) progression remains unclear. Thus, we investigated the effect of PRKF on CKD development in the residual kidney and the utility of cystatin-C (Cys-C) in evaluating renal function in living-donor kidney transplantation donors.The electronic medical records and laboratory results of 1648 kidney transplant (KT) donors and 13,834 healthy nondonors between January 2006 and November 2014 were reviewed. The predictors of PRKF and CKD diagnosed by Kidney Disease: Improving Global Outcomes (KDIGO) criteria were evaluated by multivariate analysis. CKD risk was compared between KT donors and healthy nondonors using Cox proportional hazard regression analysis following propensity score matching (PSM).The incidence of PRKF for KT donors was 49.3% (813). CKD incidence was 24.8% (408) in KT donors and 2.0% (277) in healthy nondonors. The predictors of PRKF were, male sex (odds ratio [OR], 17.32; 95% confidence interval [CI] 9.16-32.77), age (OR, 1.02; 95% CI, 1.00-1.04; P < 0.001), Cys-C concentration (OR, 1.02; 95% CI, 1.00-1.04; P = 0.02), and preoperative albumin level (OR, 0.49; 95% CI, 0.27-0.89; P = 0.02). The predictors of CKD were age (hazards ratio [HR], 1.04; 95% CI, 1.02-1.05; P < 0.001), Cys-C concentration (HR, 1.024; 95% CI, 1.012-1.037; P < 0.001), and PRKF (HR, 1.41; 95% CI, 1.04-1.92; P = 0.03). After PSM, the risk of progression to CKD was higher in KT donors than in healthy nondonors (HR, 58.4; 95% CI, 34.2-99.8; P < 0.001).Donor nephrectomy is associated with PRKF and progression to CKD. Cys-C is a useful early marker for detecting PRKF and CKD.

    In living donor liver transplantation (LDLT), an adequate hepatic venous outflow constitutes one of the basic principles of a technically successful procedure. The issue of whether the anterior sector (AS) of the right lobe (RL) graft should or should not be routinely drained has been controversial. The aim of this 10-year, single-center, retrospective cohort study was to review the evolution of our hepatic venous outflow reconstruction technique in RL grafts and evaluate the impact of routine AS drainage strategy on the outcome. The study group consisted of 582 primary RL LDLT performed between July 2004 and December 2014. The cases were divided into 3 consecutive periods with different AS venous outflow reconstruction techniques, which included middle hepatic vein (MHV) drainage in Era 1 (n=119), a more selective AS drainage with cryopreserved homologous grafts in Era 2 (n=391), and routine segment 5 and/or 8 oriented AS drainage with synthetic grafts in Era 3 (n=72). Intraoperative portal flow measurement with routine splenic artery ligation (SAL) technique (in RL grafts with a portal flow of ≥ 250 mL/min/100 g liver tissue) was added later in Era 3. These 3 groups were compared in terms of recipient and donor demographics, surgical characteristics and short-term outcome. The rate of AS venous drainage varied from 58.8% in Era 1 and 35.0% in Era 2 to 73.6% in Era 3 (P<0.001). Perioperative mortality rate of recipients significantly decreased over the years (15.1% in Era 1 and 8.7% in Era 2 vs. 2.8% in Era 3, P=0.01). After the addition of SAL technique in the 45 cases, there was only 1 graft loss and no perioperative mortality. One-year recipient survival rate was also significantly higher in Era 3 (79.6% in Era 1 and 86.1% in Era 2 vs. 92.1% in Era 3, P=0.002). Routine AS drainage via segment 5 and/or 8 veins using synthetic grafts is a technique to fit all RL grafts in LDLT. Addition of SAL effectively prevents early graft dysfunction and significantly

    By developing metallophthalocyanines and diimides as electron-donating and -accepting building blocks, herein, we report the construction of new electron donor-acceptor covalent organic frameworks (COFs) with periodically ordered electron donor and acceptor π-columnar arrays via direct polycondensation reactions. X-ray diffraction measurements in conjunction with structural simulations resolved that the resulting frameworks consist of metallophthalocyanine and diimide columns, which are ordered in a segregated yet bicontinuous manner to form built-in periodic π-arrays. In the frameworks, each metallophthalocyanine donor and diimide acceptor units are exactly linked and interfaced, leading to the generation of superheterojunctions-a new type of heterojunction machinery, for photoinduced electron transfer and charge separation. We show that this polycondensation method is widely applicable to various metallophthalocyanines and diimides as demonstrated by the combination of copper, nickel, and zinc phthalocyanine donors with pyrommellitic diimide, naphthalene diimide, and perylene diimide acceptors. By using time-resolved transient absorption spectroscopy and electron spin resonance, we demonstrated that the COFs enable long-lived charge separation, whereas the metal species, the class of acceptors, and the local geometry between donor and acceptor units play roles in determining the photochemical dynamics. The results provide insights into photoelectric COFs and demonstrate their enormous potential for charge separation and photoenergy conversions.

    To assess the effect of the intraoperative use of terlipressin on splanchnic hemodynamics and postoperative renal function in patients undergoing liver transplantation. Open-label, prospective, randomized study. Single-center study. Thirty patients who underwent elective, living-donor liver transplantation with portal pressure >20 mm Hg. Patients were assigned randomly to one of two equal groups. The control group received saline, whereas the treatment group (TP group) received an initial bolus dose of terlipressin (1 mg over 30 mins) followed immediately by a continuous infusion of 2 μg·kg(-1)·h(-1) for 48 hrs. Portal pressure and gas exchange (radial artery, portal vein, and hepatic vein, blood gas analyses, and lactate concentration) were assessed at baseline (after ligation of the hepatic artery) and 2 hrs after drug administration. Systemic hemodynamic data and calculated tissue oxygenation parameters were compared throughout the procedure. Renal function was assessed by measurement of serum cystatin C after induction of anesthesia and on the first 2 days postoperatively. After the infusion of terlipressin, portal venous pressure decreased significantly from 26.3 ± 3.3 to 21.3 ± 3.6 mm Hg (p Portal and hepatic base excess, and the level of serum lactate, did not differ between the two groups. The serum levels of both cystatin C and creatinine were significantly higher in the control group than in the TP group on postoperative day 2. Perioperative use of terlipressin abrogates the early postoperative decline in renal function of patients who have chronic liver disease and undergo liver transplantation without any detrimental effect on hepatosplanchnic gas exchange and lactate metabolism.

    The aim of this study was to evaluate utility of gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced magnetic resonance cholangiography (MRC) for the detection of biliary complications after living donor liver transplantation (LDLT). A total of 18 patients with suspected biliary complications underwent MRC. T2-weighted MRC and contrast-enhanced MRC (CE-MRC) were used to identify the biliary complications. MRC included routine breath-hold T2-weighted MRC using half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequences and Gd-EOB-DTPA-enhanced MRC T1-weighted volumetric interpolated breath-hold examination (VIBE) sequences. Before confirming the biliary complications, one observer reviewed the MRC images and the CE-MRC images separately. The verification procedures and MRC findings were compared, and the sensitivity, specificity, and accuracy of both techniques were calculated for the identification of biliary complications. The observer found six of seven biliary complications using CE-MRC. The sensitivity was 85.7% and the accuracy was 94.4%. Using MRC alone, sensitivity was 57.1% and accuracy was 55.5%. The accuracy of Gd-EOB-DTPA-enhanced MRC was superior to MRC in locating biliary leaks (p < 0.05). The usage of Gd-EOB-DTPA-enhanced MRC yields information that complements the MRC findings that improve the identification of biliary complications. We recommend the use of MRC in addition to Gd-EOB-DTPA-enhanced MRC to increase the preoperative accuracy when assessing the biliary complications after LDLT.

    We present a rare case of progressive familial intrahepatic cholestasis within a family. A 34-yearold female became a living-related liver transplant donor for her son, who had the disease. Nine years after the transplant, the mother developed severe intrahepatic cholestasis, for which she was evaluated after using an oral contraceptive drug. She presented with jaundice, pruritus, and increased bilirubin levels, together with elevated gamma glutamyl transferase and alkaline phosphatase levels. A liver biopsy revealed findings consistent with intrahepatic cholestasis. However, despite follow-up management and cessation of the insulting drug, her total bilirubin count continuously increased to 20 mg/dL and was accompanied by intractable pruritus. A total of 9 plasmapheresis sessions were performed, and she was started on a regimen of ursodeoxycholic acid (13 mg/kg/d) and cholestyramine (4 g, 3 times daily). The clinical and laboratory picture dramatically improved following cessation of the oral contraceptive, plasmapheresis sessions, and drug treatment. The patient's cholestasis normalized within 3 months, and she recovered uneventfully. A genetic analysis of the whole family revealed that both parents were heterozygous for the mutation c.124G>A in ABCB11, and the son was homozygous for this mutation. These findings supported varying degrees of bile salt export pump deficiency in the family members. Defective bile salt excretory system function can result in a wide spectrum of clinical presentations, ranging from progressive familial intrahepatic cholestasis requiring liver transplant to late-onset drug-induced cholestasis. Our findings suggest that, in a heterozygous carrier of a progressive familial intrahepatic cholestasis mutation, drug-induced cholestasis is responsive to treatment, after which the clinical picture can normalize within 3 months.

    To study the characteristics and the predictors of survival observed in our pediatric live-donor renal transplant recipients with an allograft that functioned for more than 10 yr. One hundred fifteen children underwent renal transplantation between 1976 and 1995. Of these, 30 had functioning allografts for more than 10 yr (range, 11-18). The patients included 18 males and 12 females, with a mean age at transplantation of 13 yr (range, 5-18). Characteristics of the patients, data on graft survival, and determinants of outcome were obtained by reviewing all medical charts. At most recent follow-up (January 2005), the mean daily dose of azathioprine was 1.2 mg/kg (range, 1-2) and that of prednisone was 0.16 mg/kg (range, 0.1-0.2). Mean creatinine clearance was 72 mL/min per 1.73 m(2) (range, 45-112). Acute rejection occurred in 14 (47%) patients. Seven patients had one episode, five had two episodes, and two had three episodes of acute rejection. Three patients (10%) developed malignancy. A substantial proportion of patients (44%) were short, with a height standard deviation score (SDS) less than -1.88, which is below the third percentile for age and gender. One quarter of the patients, more commonly the females, were obese. Other complications included osteoporosis in 16 (53%) patients, avascular bone necrosis in four (13%), post-transplantation diabetes mellitus in three (10%), and hypertension in 18 (60%). Twelve (40%) patients were married and 27% had children post-transplantation. The independent determinants of long-term graft survival were acute rejection and post-transplant hypertension. Despite good renal function, long-term pediatric renal transplant survivors are at risk of significant morbidity. The determinants of long-term graft survival are acute rejection and post-transplant hypertension.

    Full Text Available BACKGROUND: Postoperative respiratory complications are a major cause of mortality following liver transplantation (LT. Noninvasive ventilation (NIV appears to be effective for respiratory complications in patients undergoing solid organ transplantation; however, mortality has been high in patients who experienced reintubation in spite of NIV therapy. The predictors of reintubation following NIV therapy after LT are not exactly known. METHODS: Of 511 adult patients who received living-donor LT, data on the 179 who were treated by NIV were retrospectively examined. RESULTS: Forty-three (24% of the 179 patients who received NIV treatment required reintubation. Independent factors associated with reintubation by multivariate logistic regression analysis were controlled preoperative infections (odds ratio [OR] 8.88; 95% confidence interval (CI 1.64 to 48.11; p = 0.01, ABO-incompatibility (OR 4.49; 95% CI, 1.50 to 13.38; p = 0.007, and presence of postoperative pneumonia at the time of starting NIV (OR 3.28; 95% CI, 1.02 to 11.01; p = 0.04. The reintubated patients had a significant higher rate of postoperative infectious complications and a significantly longer intensive care unit stay than those in whom NIV was successful (p<0.0001. Of the 43 reintubated patients, 22 (51.2% died during hospitalization following LT vs. 8 (5.9% of the 136 patients in whom NIV was successful (p<0.0001. CONCLUSIONS: Because controlled preoperative infection, ABO-incompatibility or pneumonia prior to the start of NIV were independent risk factors for reintubation following NIV, caution should be used in applying NIV in patients with these conditions considering the high rate of mortality in patients requiring reintubation following NIV.

    The purpose of this study was to evaluate the efficacy and safety of transfemoral liver biopsy with a Quick-Core biopsy needle in select living donor liver transplantation (LDLT) recipients. Eight LDLT recipients underwent 9 transfemoral liver biopsy sessions. Six patients had undergone modified right lobe (mRL) LDLT, and 2 patients had undergone dual-left lobe LDLT. The indications for transfemoral liver biopsy were a hepatic vein (HV) at an acute angle to the inferior vena cava (IVC) on the coronal plane and a thin (liver parenchyma surrounding the HV to be biopsied on enhanced computed tomography. Under fluoroscopic guidance, the right inferior HV in the mRL or the left HV in the right-sided left lobe with a cranial orientation was negotiated with a 5-Fr catheter via the common femoral vein. Then, a stiffening cannula was introduced into the HV over a stiff guide wire. Needle passage was then performed with an 18- or 19-gauge Quick-Core biopsy needle. Technical success was achieved in all sessions without major complications. The median number of needle passages was 4 (range = 2-6). The median total length of obtained liver specimens in each session was 44 mm (range = 24-75 mm). The median number of portal tracts was 18 (range = 10-29), and the obtained liver specimens were adequate for histological diagnosis in all sessions. In conclusion, transfemoral liver biopsy with a Quick-Core biopsy needle is an effective and safe alternative for obtaining a liver specimen when standard transjugular liver biopsy is not feasible because of an unfavorable HV angle with respect to the IVC and/or a thin liver parenchyma surrounding the HV.

    To elucidate the role of Doppler hepatic hemodynamic parameters as surrogate markers of acute rejection (AR) after live donor liver transplantation (LDLT), serial Doppler measurements were prospectively performed during the first 2 weeks after LDLT to compare the longitudinal hepatic hemodynamic changes between patients with histologically proven AR and patients without histologically proven AR. Forty-six patients that had undergone adult-to-adult LDLT using a right lobe graft were enrolled in this study. The portal venous maximum velocity (PVV; cm/second), portal venous flow volume, hepatic arterial peak systolic velocity, hepatic arterial pulsatility index, hepatic venous maximum velocity, hepatic venous pulsatility index, and splenic arterial pulsatility index were measured. Fourteen patients were diagnosed by biopsy to have clinically relevant AR. Markedly increased PVV was seen soon after surgery and gradually decreased in both patients with clinically relevant AR and patients without clinically relevant AR. This serial change of decreasing PVV was significantly greater in patients with clinically relevant AR (P patients with clinically relevant AR was significantly lower than that in patients without clinically relevant AR (PVV on postoperative day 6: 35.6 +/- 21.3 versus 58.3 +/- 27.1 cm/second, respectively, P = 0.0080). A PVV cutoff value of 20.2 cm/second demonstrated the best accuracy for predicting clinically relevant AR. The sensitivity and specificity for predicting clinically relevant AR were 92.9% and 87.1%, respectively. The area under the curve was 0.94. In conclusion, serial Doppler measurement of hepatic parameters in LDLT is useful for the diagnosis of clinically relevant AR. Clinically relevant AR should therefore be suspected when a marked unexpected decrease in the PVV is observed.

    As the priority of LD-Domino LT is the safety of the first recipient, limitations and technical difficulties in the second recipient often occur. The most technically challenging part of LD-Domino LT is the reconstruction of the vessels. For the reconstruction of HVs, the native HVs were exteriorized as far as possible using a CUSA because longer extensive HVs are essential for facilitating the reconstruction. A
