    We report the first case of Mycoplasma hominis periaortic abscess after heart-lung transplantation. The absence of sternal wound infection delayed the diagnosis, but the patient successfully recovered with debridement surgeries and long-term antibiotic therapy. Owing to the difficulty in detection and the intrinsic resistance to beta-lactams, M. hominis infections are prone to being misdiagnosed and undertreated. M. hominis should be suspected in cases where conventional microbiological identification and treatment approaches fail. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Clostridium difficile is a major cause of diarrhea in thoracic organ transplant recipients. We investigated the epidemiology, risk factors, and outcome of Clostridium difficile infection (CDI) in heart and heart-lung transplant (HT) recipients. This is a retrospective study from 2004 to 2013. CDI was defined by diarrhea and a positive toxigenic C. difficile in stool measured by toxin enzyme immunoassay (2004-2006) or polymerase chain reaction (2007-2013). Cox proportional hazards regression was used to model the association of risk factors with time to CDI and survival with CDI following transplantation. There were 254 HT recipients, with a median age of 53 years (IQR, 45-60); 34% were female. During the median follow-up of 3.1 years (IQR, 1.3-6.1), 22 (8.7%) patients developed CDI. In multivariable analysis, risk factors for CDI were combined heart-lung transplant (HR 4.70; 95% CI, 1.30-17.01 [P=.02]) and retransplantation (HR 7.19; 95% CI, 1.61-32.12 [P=.01]). Acute cellular rejection was associated with a lower risk of CDI (HR 0.34; 95% CI, 0.11-0.94 [P=.04]). CDI was found to be an independent risk factor for mortality (HR 7.66; 95% CI, 3.41-17.21 [PClostridium difficile infection after HT is more common among patients with combined heart-lung and those undergoing retransplantation. CDI was associated with a higher risk of mortality in HT recipients. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Em situações específicas, os transplantes clínicos cardiopulmonar e pulmonar são, hoje, formas estabelecidas de tratamento para estágio final de doença cardiopulmonar e pulmonar. A obtenção de doadores adequados permanece o maior problema e a remoção de órgãos em localidades distantes é, hoje, uma necessidade. Embora muitos métodos de preservação pulmonar possam ser empregados, para períodos isquémicos de até 5 horas, a hipotermia e o uso de solução cardioplégica com infusão da solução de Collins modificada no tronco pulmonar tem sido método simples e eficiente para preservação do bloco coração-pulmão. Descrevemos, aqui, o método corrente que empregamos, com o qual os transplantes cardiopulmonar e pulmonar combinados foram sucedidos de excelente função cárdio-respiratória.In special situations, clinical heart-lung and lung transplantation are today established methods of therapy for end stage cardiopulmonary and pulmonary disease. Adequate donor availability remains a major problem and distant organ procurement is today a necessity. Although many methods of lung preservation can be used, for periods of up to 5 hours, hypothermic storage with cardioplegic arrest and pulmonary artery flush with modified Collins solution has proven to be a simple and reliable method of heart-lung preservation. We here describe our current method of heart-lung block protection, in which heart-lung and double lung transplantation were performed followed by excelent cardiac and pulmonary function.

    Our objective was to model the cost-effectiveness and economic value of routine peri-operative Staphylococcus aureus screening and decolonization of lung and heart-lung transplant recipients from hospital and third-party payer perspectives. We used clinical data from 596 lung and heart-lung transplant recipients to develop a model in TreeAge Pro 2009 (Williamsport, MA, USA). Sensitivity analyses varied S. aureus colonization rate (5-15 %), probability of infection if colonized (10-30 %), and decolonization efficacy (25-90 %). Data were collected from the Cardiothoracic Transplant Program at the University of Pittsburgh Medical Center. Consecutive lung and heart-lung transplant recipients from January 2006 to December 2010 were enrolled retrospectively. Baseline rates of S. aureus colonization, infection and decolonization efficacy were 9.6 %, 36.7 %, and 31.9 %, respectively. Screening and decolonization was economically dominant for all scenarios tested, providing more cost savings and health benefits than no screening. Savings per case averted (2012 $US) ranged from $73,567 to $133,157 (hospital perspective) and $10,748 to $16,723 (third party payer perspective), varying with the probability of colonization, infection, and decolonization efficacy. Using our clinical data, screening and decolonization led to cost savings per case averted of $240,602 (hospital perspective) and averted 6.7 S. aureus infections (4.3 MRSA and 2.4 MSSA); 89 patients needed to be screened to prevent one S. aureus infection. Our data support routine S. aureus screening and decolonization of lung and heart-lung transplant patients. The economic value of screening and decolonization was greater than in previous models of other surgical populations.

    Lung transplantation (LTx) may be denied for children on extracorporeal membrane oxygenation (ECMO) due to high risk of cerebral hemorrhage. Rarely has successful LTx been reported in children over 10 years of age receiving awake or ambulatory veno-venous ECMO. LTx following support with ambulatory veno-arterial ECMO (VA ECMO) in children has never been reported to our knowledge. We present the case of a 4-year-old, 12-kg child with heritable pulmonary artery hypertension and refractory right ventricular failure. She was successfully bridged to heart-lung transplantation (HLTx) using ambulatory VA ECMO. Initial resuscitation with standard VA ECMO was converted to an ambulatory circuit using Berlin heart cannulae. She was extubated and ambulating around her bed while on VA ECMO for 40 days. She received an HLTx from an oversized marginal lung donor. Despite a cardiac arrest and Grade 3 primary graft dysfunction, she made a full recovery without neurological deficits. She achieved 104% force expiratory volume in 1 s 33 months post-HLTx. Ambulatory VA ECMO may be a useful strategy to bridge very young children to LTx or HLTx. Patient tailored ECMO cannulation, minimization of hemorrhage, and thrombosis risks while on ECMO contributed to a successful HLTx in our patient. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

    Patients with diabetes mellitus (DM) are at higher risk for adverse outcomes following percutaneous coronary intervention (PCI). To determine whether outcomes have improved over time, we analyzed data from 2,838 consecutive patients with medically treated DM, including 1,066 patients (37.6%) treated with insulin, in the National Heart, Lung, and Blood Institute Dynamic Registry undergoing PCI registered in waves 1 (1997-1998), 2 (1999), 3 (2001-2002), 4 (2004), and 5 (2006). We compared baseline demographics and 1-year outcomes in the overall cohort and in analyses stratified by recruitment wave and insulin use. Crude mortality rates by chronological wave were 9.5%, 12.5%, 8.9%, 11.6%, and 6.6% (P value(trend) = .33) among those treated with insulin and, respectively, 9.7%, 6.5%, 4.1%, 5.4%, and 4.7% (P value(trend) = .006) among patients treated with oral agents,. The adjusted hazard ratios of death, myocardial infarction (MI), and overall major adverse cardiovascular events (death, MI, revascularization) in insulin-treated patients with DM in waves 2 to 5 as compared with wave 1 were either higher or the same. In contrast, the similar adjusted hazard ratios for oral agent-treated patients with DM were either similar or lower. Significant improvements over time in adverse events by 1 year were detected in patients with DM treated with oral agents. In insulin-treated diabetic patients, despite lower rates of repeat revascularization over time, death and MI following PCI have not significantly improved. These findings underscore the need for continued efforts at optimizing outcomes among patients with DM undergoing PCI, especially those requiring insulin treatment. Copyright © 2011 Mosby, Inc.

    Pediatric L-HLTx recipients are at risk for developing PTLD with the lung being a primary site of disease. We hypothesized that BALF is a better sample than peripheral blood for measuring EBV DNA load in this high-risk population. Archived BALF specimens from pediatric L-HLTx recipients with and without PTLD were assayed for EBV DNA load using a quantitative real time TaqMan PCR assay. These values were compared with values determined in peripheral blood by a competitive PCR assay. Fifty-five BALF specimens from 16 L-HLTx patients were evaluated. Three patients with PTLD had mean BALF EBV DNA load values almost 50-fold higher than subjects without PTLD (4.6 x 10(5) copies/mL vs. 1.0 x 10(4) copies/mL). Patients who were EBV seronegative pretransplantation (i.e., high risk for PTLD) had elevated EBV DNA load values vs. patients who were EBV seropositive pretransplantation, regardless of the diagnosis of PTLD (mean values of 3.2 x 10(5) copies/mL vs. 1.1 x 10(4) copies/mL). Lastly, BALF analysis identified all subjects with PTLD, whereas peripheral blood analysis identified only one of these cases. Therefore, it can be concluded that monitoring EBV DNA load in BALF following L-HLTx facilitates detection of PTLD in high-risk patients and may be superior to peripheral blood assays.

    Certain cardiovascular risk factors have been linked to morbidity and mortality in heart transplant (HT) patients. The sum of various risk factors may have a large cumulative negative effect, leading to a substantially worse prognosis and the need to consider whether HT is contraindicated. The objective of this study was to determine whether the risk factors usually available prior to HT result in an excess mortality in our setting that contraindicates transplantation. Consecutive patients who underwent heart transplantation from November 1987 to January 2004 were included. Heart-lung transplants, retransplants, and pediatric transplants were excluded. Of the 384 patients, 89% were men. Mean age was 52 years (range, 12 to 67). Underlying disease included ischemic heart disease (52%), idiopathic dilated cardiomyopathy (36%), valvular disease (8%), and other (4%). Variables considered risk factors were obesity (BMI >25), dyslipidemia, hypertension, prior thoracic surgery, diabetes, and history of ischemic heart disease. Survival curves by number of risk factors using Kaplan-Meier and log-rank for comparison of curves. Overall patient survival at 1, 5, 10, and 13 years was 76%, 68%, 54%, and 47%, respectively. Survival at 10 years, if fewer than two risk factors were present, was 69%; 59% if two or three factors were present; and 37% if more than three associated risk factors were present (P = .04). The presence of certain risk factors in patients undergoing HT resulted in lower survival rates. The combination of various risk factors clearly worsened outcomes. However, we do not believe this should be an absolute contraindication for transplantation.

    This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    The incidence of cutaneous melanoma has rapidly increased in the white population over the last decades. It has been estimated that the incidence doubles world-wide every 10 years. Different risk factors have been identified, including immunosuppression. The aim of our study-was to determine the relative risk of developing melanoma in the organ transplant population and the clinical and histological features of their melanomas. This retrospective study was conducted with the collaboration of 9 University Hospital Centers: Besançon, Brest, Caen, Dijon, Lille, Lyon, Nantes, Paris (Pitié-Salpétrière) and Rennes. A questionnaire was sent to the different departments of dermatology of these hospitals to obtain information on patients who had presented a melanoma after a transplantation between 1971 and 1997. During this period, there were 12,477 organ transplant recipients in the transplantation units of these 9 hospitals. Average follow-up for these patients was about 5 years and the average duration of immunosuppressive therapy was about 4.5 years. Among 12,477 organ transplant recipients, we found 17 cases of melanoma but no data could be obtain on one case: 14 occurred in renal transplant recipients and 3 in cardiac transplant recipients. Clinical and histological data were only available in 16 patients. The average time between transplantation and diagnosis of melanoma was 63 months, but it was 5 times shorter for 2 patients who had a past history of melanoma before transplantation. Two patients had a mucosal melanoma; for the cutaneous melanomas, 2 appeared on Dubreuilh melanosis, 2 were in situ melanomas, 7 were superficial spreading melanomas and 3 were nodular melanomas. The histological review of 11 cutaneous melanomas revealed a precursor nevus in 6 cases and a weak or no stroma reaction in 7/7 cases. Complete excision of the melanoma was performed in all patients except one with anorectal melanoma. Four patients died of visceral metastasis within a mean

    The purpose of our study is (1) to characterise patients with congenital heart disease undergoing heart transplantation by adult cardiac surgeons in a large academic medical centre and (2) to describe successful outcomes associated with our multidisciplinary approach to the evaluation and treatment of adults with congenital heart disease (ACHD) undergoing orthotopic heart transplantation (OHT). Heart failure is the leading cause of death in patients with ACHD leading to increasing referrals for OHT. The Penn Congenital Transplant Database comprises a cohort of patients with ACHD who underwent OHT between March 2010 and April 2016. We performed a retrospective cohort study of the 20 consecutive patients. Original cardiac diagnoses include single ventricle palliated with Fontan (n=8), dextro-transposition of the great arteries after atrial switch (n=4), tetralogy of Fallot (n=4), pulmonary atresia (n=1), Ebstein anomaly (n=1), unrepaired ventricular septal defect (n=1) and Noonan syndrome with coarctation of the aorta (n=1). Eight patients required pretransplant inotropes and two required pretransplant mechanical support. Nine patients underwent heart-liver transplant and three underwent heart-lung transplant. Three patients required postoperative mechanical circulatory support. Patients were followed for an average of 38 months as of April 2016, with 100% survival at 30 days and 1 year and 94% overall survival (19/20 patients). ACHD-OHT patients require highly specialised, complex and multidisciplinary healthcare. The success of our programme is attributed to using team-based, patient-centred care including our multidisciplinary staff and specialists across programmes and departments. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Cystic fibrosis (CF) is a disease characterized mainly by altered exocrine gland function that eventually produces irreversible dysfunction of the pancreas and lungs. The respiratory insufficiency that develops in CF patients in the advanced stages of disease can only be corrected at this time by lung or heart-lung transplantation. We describe our experience with 6 terminal phase CF patients who underwent sequential double lung transplantation (SDLT). Anesthesia was intravenous, with exhaustive hemodynamic and respiratory monitoring. During surgery the most frequently encountered hemodynamic complications were low minute volume, arterial hypotension and irregular heart rate. The main respiratory complications were hypoxemia, hypercapnia and pulmonary edema of the implanted lung, which developed in all cases to varying degrees related to the organ's state of preservation and duration of ischemia. Other complications were the need for extracorporeal circulation in 1 case, oliguria and blood loss requiring multiple transfusions. The most critical moments were at the time of clamping the pulmonary artery, the period after revascularization of the donated lung, and at the start of patient ventilation through the first implanted lung so that the second could be implanted. Although our series is small, it is of interest given the limited Spanish experience with lung transplantation in CF patients, and the good early results obtained, which are similar to those reported for other diseases.

    Transplant tourism entails movement of recipient, donor or both to a transplant centre outside their country of residence. This has been reported in many countries; and has variously been associated with organ trade. The objective of this study is to determine the frequency and pattern of transplant tourism among transplant patients in Eastern Nigeria. This is a non randomized cross sectional study. All kidney transplant patients who presented at Enugu State University Teaching Hospital Parklane Enugu and Hilton Clinics Port Harcourt in Nigeria were recruited. The clinical parameters including the transplant details of all the patients were documented. The data obtained was analysed using SPSS package. A total of one hundred and twenty six patients were studied, 76.2% were males with M:F ratio of 3.2:1 and mean age of 46.9 ± 13.3 years. Fifty four and 58.7% of the patients were managed in a tertiary hospital and by a nephrologist respectively before referral for kidney transplant. Only 15.8% of the patients had their kidney transplant without delay: finance, lack of donor, logistics including delay in obtaining travelling documents were the common causes of the delay. Ninety percent of the patients had their transplant in India with majority of them using commercial donors. India was also the country with cheapest cost ($18,000.00). 69.8% were unrelated donors, 68.2% were commercial donors and 1.6% of the donors were spouse. All the commercial donors received financial incentives and each commercial donor received mean of 7580 ± 1280 dollars. Also 30.2% of the related donors demanded financial incentive. Transplant tourism is prevalent in eastern Nigeria.

    Current transplant success allows recipients with previous contraindications to transplant to have access to this procedure with more frequency and safety. The concept of high-risk patient has changed since the first stages of transplantation. In the first studies, the high-risk concept was based on probability of early graft failure or on a patient's clinical condition to cope with high perioperatory morbimortality. Later on, this concept implied immunological factors that were crucial to ensure transplant success because hypersensitized or polytransfused patients experienced a higher risk of acute rejection and subsequent graft loss. Afterward, the presence of various comorbidities would redefine the high-risk concept for renal transplant mainly considering recipient's clinical aspects. Currently, the change in epidemiological characteristics of patients starting dialysis causes that we now deal with a greater increase of elderly patients, diabetic patients, and patients with history of cardiovascular disease. Today, high-risk patients are those with clinical features that predict an increase in the risk of perioperative morbimortality or death with functioning graft. In this review, we will attempted to analyze currents results of renal transplant outcomes in terms of patients and graft survival in elderly patients, diabetic patients, and patients with previous cardiovascular disease from the most recent experiences in the literature and from experiences in our center. In any of the groups previously analyzed, survival offered by renal transplant is significantly higher compared to dialysis. Besides, these patients are the recipient group that benefit the most with the transplant because their mortality while remaining on dialysis is extremely high. Hence, renal transplantation should be offered more frequently to older patients, diabetic patients, and patients with pretransplant cardiac and peripheral vascular disease. A positive attitude toward renal

    This initial report of the Australian and New Zealand Cardiothoracic Organ Transplant Registry summarises the results of all cardiothoracic transplants performed between February 1984 and April 1992. A total of 549 first cardiothoracic transplant procedures and six cardiac retransplant operations were performed in five transplant units throughout Australia and New Zealand. There were 466 orthotopic cardiac transplants and one heterotopic transplant with overall survival 86% at one year and 80% at five years. Two of six patients who underwent cardiac retransplantation are alive. Fifty-three heart-lung transplants were performed with 72% one year and 42% five year survival. Twenty-nine single lung transplant procedures were undertaken, with actuarial survival 72% at 12 months. Factors influencing waiting period and post-transplant survival for each type of procedure are detailed. The relative lack of donors compared with recipient demand has produced increased waiting times for every type of cardiothoracic organ transplant.

    Full Text Available Small companies working to develop products in the cardiovascular space face numerous challenges, from regulatory, intellectual property, and reimbursement barriers to securing funds to keep the lights on and reach the next development milestone. Most small companies that spin out from universities have the scientific knowledge, but product development expertise and business acumen are also needed to be successful. Other challenges include reduced interest in early-stage technologies and limited deal flow for cardiovascular products. The National Heart, Lung, and Blood Institute (NHLBI small business program is a comprehensive ecosystem designed to address these critical challenges and to provide resources and expertise to assist early-stage companies developing cardiovascular and other products within the institute’s mission. This article describes steps that NHLBI has taken to enhance our small business program to more effectively translate basic discoveries into commercial products to benefit patients and public health, including enhancing internal expertise and developing nonfinancial resources to assist small businesses as they develop their products and seek private sector investment and partnership.

  7. Liver Transplantation: Evolving Patient Selection Criteria

    Full Text Available The widespread recognition of the success of liver transplantation as a treatment for most types of acute and chronic liver failure has led to increased referrals for transplantation in the setting of a relatively fixed supply of cadaver donor organs. These events have led to a marked lengthening of the waiting time for liver transplantation, resulting in increased deaths of those on the waiting list and sicker patients undergoing transplantation. Nearly 5000 liver transplantations were performed in the United States in 2000, while the waiting list grew to over 17,000 patients. The mounting disparity between the number of liver transplant candidates and the limited supply of donor organs has led to reassessment of the selection and listing criteria for liver transplantation, as well as revision of organ allocation and distribution policies for cadaver livers. The development of minimal listing criteria for patients with chronic liver disease based on a specific definition for decompensation of cirrhosis has facilitated the more uniform listing of patients at individual centres across the United States. The United Network for Organ Sharing, under pressure from transplant professionals, patient advocacy groups and the federal government, has continuously revised allocation and distribution policies based on the ethical principles of justice for the individual patient versus optimal utility of the limited organ supply available annually. Beginning in 2002, it is likely that the Model for End-stage Liver Disease (MELD score will be implemented to determine disease severity and direct donor organs to the sickest patients rather than to those with the longest waiting times.

    With the advances in congenital cardiac surgery and postoperative care, an increasing number of children with complex congenital heart disease now reach adulthood. There are already more adults than children living with a congenital heart defect, including patients with complex congenital heart defects. Among these adults with congenital heart disease, a significant number will develop ventricular dysfunction over time. Heart failure accounts for 26-42% of deaths in adults with congenital heart defects. Heart transplantation, or heart-lung transplantation in Eisenmenger syndrome, then becomes the ultimate therapeutic possibility for these patients. This population is deemed to be at high risk of mortality after heart transplantation, although their long-term survival is similar to that of patients transplanted for other reasons. Indeed, heart transplantation in adults with congenital heart disease is often challenging, because of several potential problems: complex cardiac and vascular anatomy, multiple previous palliative and corrective surgeries, and effects on other organs (kidney, liver, lungs) of long-standing cardiac dysfunction or cyanosis, with frequent elevation of pulmonary vascular resistance. In this review, we focus on the specific problems relating to heart and heart-lung transplantation in this population, revisit the indications/contraindications, and update the long-term outcomes.

    2017-09-01

    Migraine headache is a primary neurologic disease affecting millions of people worldwide. As a consequence, quality of life is diminished, productivity suffers (through loss of work force), and treatment costs are substantial. The occurrence rate in the general population is quite high, with women accounting for 3 of every 4 cases. Between January 2011 and May 2012, a total of 221 patients received hair transplants. Another 590 patients underwent hair transplantation between June 2012 and December 2016. Initially (first interval), patients were not questioned on migraine headaches in preoperative visits, but questioning was regularly done thereafter. Overall, 150 patients given transplants in the first period were surveyed by phone regarding preoperative migraine headaches. Aside from the 1 incidental discovery, no other instances of migraine emerged. Headache origins were occipital-frontal in 2 patients, occipital-temporal in 2 patients, and occipital-temporal-frontal in the 2 others. Donor/receiver areas in hair transplantation and migraine trigger zones shared locations. Headache frequencies ranged from 4 to 8 days per month (average, 6 days), and pain scores were 5-8 (10 being highest). Duration of pain was 3-5 hours (average, 4 hours). All six patients had used various medications, such as triptans, ergot, and nonsteroidal anti-inflammatory drugs, before hair transplantation. The 1 female patient was a 32-year-old seeking treatment for alopecia, with a 6-year history of migraine headaches. The male patients presenting with androgenetic alopecia (grade 4-5 by Norwood classification) had 6- to 20-year migrainous histories. After hair transplantation, each migraine sufferer was checked once in the first month and then once every 3 months. Those who could not appear in person after the first year were evaluated by phone every 3 months. Migraine headaches had ceased in all 6 patients, none of whom used medical treatments for migraines thereafter. The postoperative

    Fusarium is a fungal pathogen of immunosuppressed lung transplant patients associated with a high mortality in those with severe and persistent neutropenia. The principle portal of entry for Fusarium species is the airways, and lung involvement almost always occurs among lung transplant patients with disseminated infection. In these patients, the immunoprotective mechanisms of the transplanted lungs are impaired, and they are, therefore, more vulnerable to Fusarium infection. As a result, fusariosis occurs in up to 32% of lung transplant patients. We studied fusariosis in 6 patients following lung transplantation who were treated at Massachusetts General Hospital during an 8-year period and reviewed 3 published cases in the literature. Cases were identified by the microbiology laboratory and through discharge summaries. Patients presented with dyspnea, fever, nonproductive cough, hemoptysis, and headache. Blood tests showed elevated white blood cell counts with granulocytosis and elevated inflammatory markers. Cultures of Fusarium were isolated from bronchoalveolar lavage, blood, and sputum specimens. Treatments included amphotericin B, liposomal amphotericin B, caspofungin, voriconazole, and posaconazole, either alone or in combination. Lung involvement occurred in all patients with disseminated disease and it was associated with a poor outcome. The mortality rate in this group of patients was high (67%), and of those who survived, 1 patient was treated with a combination of amphotericin B and voriconazole, 1 patient with amphotericin B, and 1 patient with posaconazole. Recommended empirical treatment includes voriconazole, amphotericin B or liposomal amphotericin B first-line, and posaconazole for refractory disease. High-dose amphotericin B is recommended for treatment of most cases of fusariosis. The echinocandins (for example, caspofungin, micafungin, anidulafungin) are generally avoided because Fusarium species have intrinsic resistance to them. Treatment

    Full Text Available Objective: It was aimed to identify skin findings those were seen in patients who undergone renal transplantation. Methods: Patients who have been followed in Erciyes University Nephrology Hospital renal transplantation outpatient clinic were included in the study. They were evaluated for dermatologic findings during routine controls. Age, gender, transplantation date, identity of organ donor, history of medications, dermatological history and dermatological findings during examination were recorded. Biopsy was performed when needed. Results: In total 94 patients, 25 female (26.6% and 69 male (73.4%, were recruited to the study. Mean age was 36±10 years. The most frequent skin finding was drug-related acne (n=20. Most common infectious disease was verruca (n=17. There were viral disease other than verruca such as herpes zoster (n=3, superficial mycosis such as onychomycosis (n=5, tinea versicolor, tinea pedis and bacterial skin disease (n=2, and paronychia (n=1 and pre-malign lesions such as actinic cheilitis and bowenoid papulosis. Besides these, stria (n=3, kserosis (n=2, cornu cutaneum, café-au-lait spots, sebaceous hyperplasia and seborrheic dermatitis, skin tag, hypertrichosis, unguis incarinatus and calcinosis were other skin findings those were seen. No malign skin lesion was observed in any of patients. Conclusion: Miscellaneous skin lesions should develop in patients those undergone renal transplantation due to long-term utilization of various immunosuppressive drugs.

    To review the characteristics and evolution of the fungal spectrum, and the risk factors causing fungal infection, and to make progress in diagnosing fungal infection after organ transplantation. An English-language literature search (MEDLINE 1990 - 2000) and bibliographic review of textbooks and review articles. Twenty-three articles were selected from the literature that specifically addressed the stated purpose. Fungal infections in organ transplant patients were generally divided into two types: (1) disseminated primary or reactivation infection with one of the geographically restricted systemic mycoses; (2) opportunistic infection by fungal species that rarely cause invasive infection in normal hosts. The risk factors of fungal infection after a transplant can be evaluated and predicted according to the organ recipient's conditions before, during and after the transplant. Progress in early diagnostic methods during the past 10 years has mainly revolved around two aspects, culture and non-culture. It is important to undertake a systemic evaluation on the condition of the organ recipient before, during and after a transplant; should any risk factor for fungal infection be suspected, diagnosis should be made as early as possible by employing mycological techniques including culture and non-culture methods.

    There is an increasing demand for outcomes analysis, including quality of life and financial analysis, following medical interventions and surgical procedures. We analyzed outcomes for 100 consecutive patients undergoing liver transplantation during a period of case management revision. Patient survival was calculated by Kaplan-Meier actuarial methods. The Karnofsky performance status was objectively assessed for surviving patients up to 6 years after transplantation and was evaluated by repeated measures analysis of variance and covariance. Subjective evaluation of quality of life over time was obtained using the Psychosocial Adjustment to Illness Scale. The correlations between time and scale were calculated. Financial data were accumulated from billing records. Six-month, 1-year, 2-year, and 3- through 5-year survival was 86%, 84%, 83%, and 78%, respectively. Karnofsky performance status confirmed poor functional status preoperatively with a mean of 53 +/- 2, but significantly improving to 72 +/- 2 at 3 months, 80 +/- 2 at 6 months, 90 +/- 1 at 1 year, 92 +/- 1 at 2 years, 94 +/- 1 at 3 years, 96 +/- 1 at 4 years, and 97 +/- 1 at 5 years (P <0.001). Psychosocial Adjustment to Illness Scale scores demonstrated significant improvement following transplantation overall (r = -0.33), improving most in sexual relationships (r = -0.41), and domestic environment (r = -0.35; P <0.001). Median length of stay for the first half of the patients was 19 days declining to 11 days for the second half. Median hospital charges declined from $105,000 to $90,000. Quality of life parameters assessed both by care givers (Karnofsky) and by patients (Psychosocial Adjustment to Illness Scale) improved dramatically following transplantation and over time, demonstrating that liver transplantation effectively restores a good quality of life. Outcomes can be improved while reducing length of stay and charges through modifications in case management.

    Present experience concerning the contribution of nuclear medicine to the follow-up of transplanted organs, such as kidneys, livers, and hearts, is based on analyses of the course of more than 1100 transplanted kidneys, 200 orthotopic livers, and 100 orthotopic transplanted hearts. In the kidneys, 99m Tc-DTPA is used to assess both perfusion and glomerular filtration rate, e.g. rejection and acute tubular necrosis. In combination with ultrasound nuclear medicine procedures serve in the detection of surgical complications, e.g. urinary leakage, vascular occlusion. In the follow-up of liver transplanted patients cholescintigraphy with 99m Tc-DISPA (or JODIDA) is a test for the patency and integrity of bile ducts or hepaticoenterostomy in the grafted patient, e.g. bile leakage, stenosis. The nutritive hepatic flow is estimated by colloid uptake measurements 99m Tc-MMS and the corresponding RES function. Despite inherent limitations the arterial-to-total perfusion ratio is measured with 99m Tc-DTPA, e.g. rejection, vascular problem. Rejection monitoring in orthotopic transplanted hearts includes routine MUGA (multiple gated blood acquisition) studies. The left ventricular ejection fraction is of major value compared to regional parameters of mortality (Fourier analysis) e.g. rejection, infection. 111 In-oxine granulocyte scans and methods for the detection of bleeding are of minor importance and relevance in the follow-up of transplanted organs. The article discusses the value of the diagnostic procedures in terms of statistical parameters, such as sensitivity, specifity, and accuracy. (orig./MG) [de

    To identify the psychiatric illnesses in patients with hematological/oncological disorders encountered during blood and bone marrow transplantation. All consecutive patients, aged 15 years and above, who fulfilled inclusion and exclusion criteria and underwent blood and bone marrow transplantation, were enrolled in this study. Psychiatric assessment comprised of a semi-structured interview based on Present Status Examination (PSE). The psychiatric diagnosis was made on the basis of International Classification of Diseases (ICD-10) system of classification devised by W.H.O. Eighty patients, who fulfilled the inclusion criteria, were inducted in this study. Thirty (37.5%) cases were found to have psychiatric disorders. Out of the total, 60 (75%) were males and 20 (25%) females. Adjustment disorder was the most frequent diagnosis (n=12), followed by major depression (n=7). Rest of the diagnoses made were generalized anxiety disorder, acute psychotic disorder, delirium and depressive psychosis. High psychiatric morbidity associated with blood and bone marrow transplantation was observed. It indicates the importance of psychiatric intervention during the isolation period of BMT as well as pre-transplant psychiatric assessment and counseling regarding procedure. (author)

    Meniscal pathology in skeletally immature patients includes meniscal tears and discoid lateral meniscus. Total or subtotal meniscectomy may occur in patients with discoid lateral meniscus or severe meniscal tears. Meniscal transplantation may be an option in skeletally immature patients status after total or subtotal meniscectomy with knee symptoms or dysfunction. This study focuses on the surgical technique and short-term outcomes of meniscus transplantation in skeletally immature patients. We reviewed our clinical database for skeletally immature patients who had undergone meniscus transplantation with a minimum of 2 years of follow-up. Patients were contacted, invited for a physical exam, and asked to complete a Pedi-IKDC, Lysholm, and Tegner outcomes questionnaire. The study protocol was approved by the responsible institutional review board. Three patients (two females/one male) were eligible for the study, each of whom responded to our invitation indicating availability for physical exam and questionnaire. Two patients had undergone subtotal discoid meniscus resection, leading to early lateral compartment degeneration. One patient developed advanced degeneration after a delay in treatment for a medial bucket-handle tear associated with anterior cruciate ligament rupture. The mean age of the patients at the time of surgery was 12.6±2.3 years. At a mean follow-up of 31±20 months, the mean Pedi-IKDC score was 68.3±4, the mean Lysholm was 55.7±22.3, and the median Tegner was 7 points. There were no indications of growth deformity during the regular postoperative radiological assessments. One patient required subsequent lysis of adhesions along the lateral mini arthrotomy and mobilization under anesthesia. The other two patients were able to return to sports at the same level as before meniscus transplantation and were able to do so within 9 months postoperatively. Over-resection of discoid menisci as well as untreated meniscus injury, the latter typically in

    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

  1. Kidney transplant in diabetic patients: modalities, indications and results

    2009-08-01

    Full Text Available Abstract Background Diabetes is a disease of increasing worldwide prevalence and is the main cause of chronic renal failure. Type 1 diabetic patients with chronic renal failure have the following therapy options: kidney transplant from a living donor, pancreas after kidney transplant, simultaneous pancreas-kidney transplant, or awaiting a deceased donor kidney transplant. For type 2 diabetic patients, only kidney transplant from deceased or living donors are recommended. Patient survival after kidney transplant has been improving for all age ranges in comparison to the dialysis therapy. The main causes of mortality after transplant are cardiovascular and cerebrovascular events, infections and neoplasias. Five-year patient survival for type 2 diabetic patients is lower than the non-diabetics' because they are older and have higher body mass index on the occasion of the transplant and both pre- and posttransplant cardiovascular diseases prevalences. The increased postransplant cardiovascular mortality in these patients is attributed to the presence of well-known risk factors, such as insulin resistance, higher triglycerides values, lower HDL-cholesterol values, abnormalities in fibrinolysis and coagulation and endothelial dysfunction. In type 1 diabetic patients, simultaneous pancreas-kidney transplant is associated with lower prevalence of vascular diseases, including acute myocardial infarction, stroke and amputation in comparison to isolated kidney transplant and dialysis therapy. Conclusion Type 1 and 2 diabetic patients present higher survival rates after transplant in comparison to the dialysis therapy, although the prevalence of cardiovascular events and infectious complications remain higher than in the general population.

    Despite the advances in the care of recipients and in immunosuppression, long-term graft survival has experienced little improvement in the last 10 years. An important number of recipients present progressive loss of graft function and have to be readmitted on dialysis therapy. Before starting dialysis, these patients are re-exposed to the complications of chronic renal failure but there are no specific guidelines for their treatment. The Kidney Disease Quality Initiative Advisory Board clinical practice guidelines given for the non-transplant chronic kidney disease patients have been recommended for ameliorating their clinical situation and the rate of progression of graft failure. The time when dialysis has to be restarted and the type of dialysis procedure, hemodialysis or peritoneal dialysis, are under discusion. But there is no evidence about the superiority of either type of dialysis procedure. Systematic graft nephrectomy has been considered to improve the inflammatory status of the patients with a failed graft which could contribute to a worse control of some complications such as anemia and to the increased rates of cardiovascular mortality. As in the patients with primary end-stage renal disease, retransplantation is the best treatment for a patient with a failed graft. Due to the shortage of organs for transplantation the number of patients who are retransplanted has remained stable. Recurrent diseases such as glomerulonephritis, lyphoproliferative diseases, BK virus nephopathy and previous non-adherence to the treatment do not necessarily preclude retransplantation.

    To explore the lived experience of the patients post-haematopoietic stem cell transplantation and specifically after engraftment and before discharge. Patients post-stem cell transplantation experience significant changes in all life aspects. Previous studies carried out by other researchers focused mainly on the postdischarge experience, where patients reported their perceptions that have always been affected by the life post-transplantation and influenced by their surroundings. The lived experience of patients, specifically after engraftment and prior to discharge (the "transition" phase), has not been adequately explored in the literature. Doing so might provide greater insight into the cause of change post-haematopoietic stem cell transplantation. This study is a phenomenological description of the participants' perception about their lived experience post-haematopoietic stem cell transplantation. The study used Giorgi's method of analysis. Through purposive sampling, 15 post-haematopoietic stem cell transplantation patients were recruited. Data were collected by individual interviews. Data were then analysed based on Giorgi's method of analysis to reveal the meaning of a phenomenon as experienced through the identification of essential themes. The analysis process revealed 12 core themes covered by four categories that detailed patients lived experience post-haematopoietic stem cell transplantation. The four categories were general transplant experience, effects of transplantation, factors of stress alleviation and finally life post-transplantation. This study showed how the haematopoietic stem cell transplantation affected the patients' physical, psychological and spiritual well-being. Transplantation also impacted on the patients' way of thinking and perception of life. Attending to patients' needs during transplantation might help to alleviate the severity of the effects and therefore improve experience. Comprehensive information about transplantation needs

    Full Text Available During April, 1991 and September, 1993, eighteen patients with major thalassemia admitted to Shariati BMT center. Seventeen patients were transplanted were from HLA identical siblings and one from. his HLA identical father. Eleven of the donors were the known cases of minor thalassemia. The range of patients' age was within 3-10 years (with the average of 5 years and 11 months. Among them, seven patients were male and eleven were female. As the other international BMT centers, we classified our patients into three classes. Our criteria for this classification were hepatomegaly, ferretin, and liver fibrous; 60% of our patients were put in class I and 40% in class II. All of our patients revealed a GVHD (severe graft vs. host disease three weeks post-BMT as pruritus, diarrhea, and skin erythema especially in hands and feet. Two of the patients showed severe GVHD. One of the patients had chimerism after BMT. Although one year after BMT has passed, the patients is still depended on blood transfusion. One patient, despite graft rejection, died nine months post-BMT; another one died after +70 due to GVHD. During 2.5 years, the overall graft survival rate was 88% in our center

    Objective: To evaluate the prevalence and contributing factors causing post transplant erythrocytosis in renal transplant patients. Methods: This retrospective study was conducted on live related renal transplant patients at SIUT. The records of all transplant recipients transplanted between April 2008 and December 2008 and who had at least 24 months follow up were studied. Patients in whom haematocrit exceeded 51% and those who received treatment for it were classified into post transplant erythrocytosis group. Results: Out of 200 renal transplant patients who had functioning graft at the time of analysis, 40 (20%) developed post transplant erythrocytosis (HCT >51%) after a mean interval of 9.5+- 2.5 months. Patients with erythrocytosis were mostly males (95% in PTE group vs 73.75% in non PTE group) ,had a shorter period on dialysis before undergoing renal transplantation (9.28 months in PTE group vs 14.56 months in non PTE group) and had relatively better graft function at the onset of erythrocytosis as judged by serum creatinine (S. Creatinine of 1.06+-0.29 mg/dl in PTE group vs 1.37 +- 0.51 mg/dl in non PTE group). No thrombotic complications were observed. All patients with erythrocytosis were treated with enalapril (ACE inhibitors) and 28 out of 40 required phlebotomy in addition to ACE inhibitors. The mean HCT at the time of last follow up in treated patients was 48.61+-1.85%. Conclusion: Post transplant erythrocytosis generally occurs in male patients with good graft function, thrombotic complications are of rare occurrence and response to ACE inhibitors is good.

  12. Impact of donor-specific HLA antibodies in transplantation, a review of the literature published in the last three years.

    Science.gov (United States)

    Kaneku, Hugo

    2010-01-01

    This chapter summarizes some of the recent findings published on the role in organ transplantation of HLA antibodies, and--more important--donor-specific HLA antibodies. The negative impact of both, preformed and de novo DSA is now better recognized in recipients of kidney, heart, lung, liver, pancreas, islet cells and bone marrow transplants. An appropriate design of a schedule to monitor HLA antibodies may identify patients at higher risk for immunological events earlier and allow interventions to avoid later graft loss. The value of strategies like preemptive treatment of antibodies and the use of new agents like bortezomib and eculizumab are of interest and need further investigation.

    Nitric oxide (NO) is present in exhaled air in humans and its level may decrease in heart diseases. In the present study we prospectively investigated how heart transplantation treated with oral immunosuppresive drugs based on ciclosporine A influences the exhaled NO concentration (exNO). The study was performed in 17 patients after heart transplantation in various time after procedure and 15 nonsmoking healthy volunteers as a control group. Patients after heart transplantation were free of clinical signs of rejection. End-tidal concentration of exNO was measured by the use of a chemiluminescence method. We found no statistically significant differences in the exNO level between patients after heart transplantation and healthy controls (6.81+/-2.70 part per billion (ppb) in the transplant group vs. 6.01+/-3.43 ppb in the control group). We conclude that heart transplantation and immunosuppresive therapy do not influence the exhaled NO concentration.

    Conclusion: Inter-AEMD and intra-AEMD were prolonged in patients who underwent heart transplantation as compared to a control population. This may explain the increased atrial fibrillation and other atrial arrhythmia incidences associated with the biatrial anastomosis heart transplantation technique and may contribute to the treatment of atrial fibrillation in this special patient group.

    A multimedia program could effectively advise patients about preparing for transplantation while on the waiting list for a kidney transplant. This study aimed to compare knowledge about transplant preparation for patients on a kidney transplant waiting list before and after participating in a multimedia program, and to evaluate patient satisfaction with the multimedia program. Research design was quasiexperimental with the use of 1 group. Subjects were 186 patients on the kidney transplant waiting list after HLA matching in Ramathibodi Hospital. The questionnaires were developed by the researchers. The statistical tools used were basic statistics, percentage, average, standard deviation, and the difference of score between before and after participation in the multimedia program (t test). The evaluation knowledge for transplant preparation for kidney transplant waiting list patients after participating in the multimedia program averaged 85.40%, and there was an increased improvement of score by an average 3.27 out of a possible full score of 20 (P multimedia program had good average, 4.58.

    To investigate the relationship between the heart-lung ratio (HLR) assessed with exercise 99 Tc m N-NOET myocardial perfusion imaging and coronary artery disease (CAD), 10 normal volunteers (7 male and 3 female, aged 40.0 ± 5.8 years), and 40 suspected CAD patients (21 male and 19 female, aged 55.2 ± 8.5 years) underwent exercise (30 min)-delayed (2 and 4 h postinjection) 99 Tc m -NOET gated myocardial perfusion imaging, and the HLR at different time was calculated. 13 patients among them took the coronary angiography in two months. According to the exercise heart-lung ratio (EXHLR), 50 subjects were divided into two groups. G1(n=36, EXHLR≥2) included 10 normal volunteers, 5 patients with normal coronary arteries, and the rest 21 patients had no relevant symptom and cardiac event in the follow-up period of 4 to 12 months. The image was normal in all of the subjects in G1. In G2 (n=14, EXHLR 99 Tc m N-NOET may be useful as a diagnostic index in CAD because it is more sensitive than myocardial perfusion imaging.

  1. Unilateral lung transplantation for pulmonary fibrosis.

    Science.gov (United States)

    1986-05-01

    Improvements in immunosuppression and surgical techniques have made unilateral lung transplantation feasible in selected patients with end-stage interstitial lung disease. We report two cases of successful unilateral lung transplantation for end-stage respiratory failure due to pulmonary fibrosis. The patients, both oxygen-dependent, had progressive disease refractory to all treatment, with an anticipated life expectancy of less than one year on the basis of the rate of progression of the disease. Both patients were discharged six weeks after transplantation and returned to normal life. They are alive and well at 26 months and 14 months after the procedure. Pulmonary-function studies have shown substantial improvement in their lung volumes and diffusing capacities. For both patients, arterial oxygen tension is now normal and there is no arterial oxygen desaturation with exercise. This experience shows that unilateral lung transplantation, for selected patients with end-stage interstitial lung disease, provides a good functional result. Moreover, it avoids the necessity for cardiac transplantation, as required by the combined heart-lung procedure, and permits the use of the donor heart for another recipient.

    Adverse outcomes of influenza & pneumococcal infections in solid organ transplant recipients have been well documented. Vaccinations are therefore recommended by multiple guidelines. Despite emerging evidence of the safety & effectiveness among immunosuppressed patients, most vaccines are still underutilized, we conducted a survey among the renal transplant patients in Beaumont Hospital to determine the awareness and uptake of vaccinations. Questionnaires were handed to patients during a clinic visit over a span of 2 weeks and 250 questionnaires were posted out to randomly selected transplant patients, The Questionnaire addressed various aspects including the awareness of importance of vaccinations, source of information, if they were up to date with the vaccines & where did they receive it?

    To assess the degree of immunosuppressive medication adherence in kidney transplant patients (KTPs) and to determine if there is a difference in the rate of adherence to tacrolimus (Tac), cyclosporine (CsA) and sirolimus (Sir). From a total of 63 KTPs treated at the Clinic of Nephrology, Clinical Centre Niš, Serbia, 60 participated in the study by responding to questionnaires. They were divided into the adherence group (n = 43) and the nonadherence group (n = 17) according to their degree of adherence which was measured using a validated survey form, the simplified medication adherence questionnaire. The KTP adherence to the different immunosuppressive regimens (Tac, CsA and Sir) was compared. Statistical analysis was performed using the Student t test. Adherence was observed in 43 (71.7%) patients, and only 17 (28.3%) did not follow the prescribed therapy. The estimated glomerular filtration rate was significantly lower in the nonadherence group (38.52 ± 18.22 ml/min) than in the adherence group (52.43 ± 16.91 ml/min, p adherers and the nonadherers (6.30 ± 2.06 vs. 5.0 ± 1.52 ng/ml, p adherence. Nonadherence was associated with worse graft function and a lower Tac level. Knowledge about the degree of adherence could help the early identification of nonadherent patients and the development of strategies to improve this. © 2014 S. Karger AG, Basel

    Full Text Available OBJECTIVE: Poor sleep quality is one of the factors that adversely affects patient quality of life after kidney transplantation, and sleep disorders represent a significant cardiovascular risk factor. The objective of this study was to investigate the prevalence of changes in sleep quality and their outcomes in kidney transplant recipients and analyze the variables affecting sleep quality in the first years after renal transplantation. METHODS: Kidney transplant recipients were evaluated at two time points after a successful transplantation: between three and six months (Phase 1 and between 12 and 15 months (Phase 2. The following tools were used for assessment: the Pittsburgh Sleep Quality Index; the quality of life questionnaire Short-Form-36; the Hospital Anxiety and Depression scale; the Karnofsky scale; and assessments of social and demographic data. The prevalence of poor sleep was 36.7% in Phase 1 and 38.3% in Phase 2 of the study. RESULTS: There were no significant differences between patients with and without changes in sleep quality between the two phases. We found no changes in sleep patterns throughout the study. Both the physical and mental health scores worsened from Phase 1 to Phase 2. CONCLUSION: Sleep quality in kidney transplant recipients did not change during the first year after a successful renal transplantation.

    International records indicate that only 2.6% of patients with heart transplants have valvular heart disease. The study aim was to evaluate the epidemiological and clinical profile of patients with valvular heart disease undergoing heart transplantation. Between 1985 and 2013, a total of 569 heart transplants was performed at the authors' institution. Twenty patients (13 men, seven women; mean age 39.5 +/- 15.2 years) underwent heart transplant due to structural (primary) valvular disease. Analyses were made of the patients' clinical profile, laboratory data, echocardiographic and histopathological data, and mortality and rejection. Of the patients, 18 (90%) had a rheumatic etiology, with 85% having undergone previous valve surgery (45% had one or more operations), and 95% with a normal functioning valve prosthesis at the time of transplantation. Atrial fibrillation was present in seven patients (35%), while nine (45%) were in NYHA functional class IV and eight (40%) in class III. The indication for cardiac transplantation was refractory heart failure in seven patients (35%) and persistent NYHA class III/IV in ten (50%). The mean left ventricular ejection fraction (LVEF) was 26.6 +/- 7.9%. The one-year mortality was 20%. Histological examination of the recipients' hearts showed five (27.7%) to have reactivated rheumatic myocarditis without prior diagnosis at the time of transplantation. Univariate analysis showed that age, gender, LVEF, rheumatic activity and rejection were not associated with mortality at one year. Among the present patient cohort, rheumatic heart disease was the leading cause of heart transplantation, and a significant proportion of these patients had reactivated myocarditis diagnosed in the histological analyses. Thus, it appears valid to investigate the existence of rheumatic activity, especially in valvular cardiomyopathy with severe systolic dysfunction before transplantation.

HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient's long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    The clinical challenges confronting patients with human immunodeficiency virus (HIV) have shifted from acquired immunodeficiency syndrome (AIDS)-related illnesses to chronic diseases, such as coronary artery disease, chronic lung disease, and chronic anemia. With the growing burden of HIV-related heart, lung, and blood (HLB) disease, the National Heart, Lung, and Blood Institute (NHLBI) recognizes it must stimulate and support HIV-related HLB research. Because HIV offers a natural, accelerated model of common pathological processes, such as inflammation, HIV-related HLB research may yield important breakthroughs for all patients with HLB disease. This paper summarizes the cardiovascular recommendations of an NHLBI Working Group, Advancing HIV/AIDS Research in Heart, Lung, and Blood Diseases, charged with identifying scientific priorities in HIV-related HLB disease and developing recommendations to promote multidisciplinary collaboration among HIV and HLB investigators. The working group included multidisciplinary sessions, as well as HLB breakout sessions for discussion of disease-specific issues, with common themes about scientific priorities and strategies to stimulate HLB research emerging in all 3 groups.

    Preeclampsia is a multisystemic syndrome with unknown etiology and characterized by abnormal vascular placentation response. Patients with renal transplantation restore them fertility 10 months after the intervention. To evaluate incidence of preeclampsia and maternal-perinatal outcome in patients with renal transplantation. Comparative, observational and retrospective study performed in pregnant patients with renal transplantation, from December 1999 to April 2008 at Perinatology of Hypertensive Diseases Department of the Unidad Medica de Alta Especialidad de Ginecoobstetricia Luis Castelazo Ayala, IMSS. Davison' guide, descriptive statistic, and Fischer exact test were used. Thirty patients were analyzed, 27 cases satisfy Davison's recommended guidelines, and the rest did not achieve these criteria (p = 0.001). Preeclampsia occurred in 15 cases (50%), preterm delivery in 15 (50%), and fetal growth restriction in 6 (20%). Among the 11 patients with previous chronic hypertension, 8 developed superimposed preeclampsia (72%), and 9 had delivery before 37 weeks of gestation (82%). Malfunction of renal transplantation, before pregnancy, was associated with maternal and perinatal poor outcome (p = 0.006). There were no maternal deaths, but one perinatal (3%) Successful pregnancy is possible in patients with renal transplantation, however there is a high risk of preeclampsia, infection, and fetal growth restriction. Patients with renal transplantation must fulfill Davison's pre-pregnancy guidelines.

    Full Text Available Clostridium difficile infection (CDI represents one of the most common healthcare-associated infections. Due to increasing numbers of recurrences and therapy failures, CDI has become a major disease burden. Studies have shown that fecal microbiota transplantation (FMT can both be a safe and highly efficacious therapy for patients with therapy-refractory CDI. However, patients undergoing solid organ transplantation are at high risk for CDI due to long-term immunosuppression, previous antibiotic therapy, and proton pump inhibitor use. Additionally, these patients may be especially prone to adverse events related to FMT. Here, we report a successful FMT in a patient with severe therapy-refractory CDI after liver transplantation.

    The aim of the study is to describe both professional and social activities of patients after heart transplant. Ninety-five heart transplant patients treated at the Silesian Center for Heart Diseases in Zabrze were surveyed, comprising 29 women (30.5%) and 66 men (69.5%). The average age of respondents was 54.3 years old (standard deviation (SD) = 15 years); the average period that had elapsed since the heart transplant was 7.1 years (SD = 4 years). We designed a questionnaire as a tool for collecting information from patients. Twenty-five percent of patients worked at the time of completion of the questionnaire. Eighty percent of those patients were working before and after the transplant, 20%--only after transplantation (p surveyed, 52.5% said that their financial situation had not changed whereas 34.5% of those surveyed reported a change for the worse. Thirty-seven percent of respondents reported changes in family relationships. Seventy-seven percent reported that they received help from family members, as compared with 19% who did not. Only 25.3% of the patients treated at the Silesian Centre for Heart Diseases after heart transplant are employed and it is one of the lowest employment rates in this category of patients in Europe. One third of working patients have the same work place as they had before their operation. Heart transplant is a cause of changes in family relationships. Most often family bonds are strengthened but sometimes family members become nervous, impatient and unwilling to talk about the transplant.

    2009-06-01

    Full Text Available Abstract Background Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality. Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. Methods This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group or 2 ferrous sulphate slow-release tablets daily (oral iron group. The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to ≥110 g/l in iron-treated patients, assuming an α of 0.05.

The objective of this study was to examine the representations of the transplanted organ and their relationship with emotional and mood factors, illness perceptions, and the functioning of the transplanted organ. One hundred and sixty-four kidney transplant patients were assessed using the Spielberger Anxiety Inventory, the Beck’s Depression Scale, the Posttraumatic Growth Inventory, the Brief Illness Perception Questionnaire, and the Transplanted Organ Questionnaire. Medical parameters were collected from the routine clinical blood tests (serum creatinine and estimated glomerular filtration rate levels and biopsy results. Our most outstanding results suggest that kidney-transplanted patients’ illness representations are associated with health outcomes. The Transplanted Organ Questionnaire “psychological rejection” subscale was connected with higher serum creatinine and estimated glomerular filtration rate levels. Logistic regression analysis showed that psychological rejection subscale, Brief Illness Perception Questionnaire, and Posttraumatic Growth Questionnaire total scores were associated with graft rejection. These results may serve as a basis for the development of complex treatment interventions, which could help patients to cope with the bio-psycho-social challenges of integrating the new organ as part of their body and self.

    To analyze self-care in renal transplantation patients. Qualitative research, inspired in the post-structuralism. The empirical material was composed by the posts of a Facebook group of Renal Transplantation Patients, collected from February to May of 2016, totaling 53 posts from 35 participants. The research data were analyzed under the perspective of cultural analysis, using theories derived from Foucault. Self-care in renal transplantation patients was identified by the preoccupation with themselves and others, habits and lifestyles, restrictions and limitations that the disease imposes, such as lessons, ways of living and lifestyles after the procedure. This experience forces people that have been submitted to renal transplantation to reflect on the lifestyle they follow. The group also stimulates adhesion to treatment.

    OBJECTIVES To evaluate the prevalence of cholecystopathy in chronic renal patients awaiting kidney transplants. INTRODUCTION The prevalence and management of cholelithiasis in renal transplant patients is not well established. METHODS A total of 342 chronic renal failure patients on the waiting list for a kidney transplant were studied. Patients were evaluated for the presence of cholelithiasis and related symptoms, previous cholecystectomies and other abdominal surgeries, time on dialysis, and general data (gender, age, number of pregnancies, and body mass index). RESULTS Cholelithiasis was found in 41 out of 342 patients (12%). Twelve of these patients, all symptomatic, had previously undergone cholecystectomies. Five out of 29 patients who had not undergone surgery were symptomatic. Overall, 17 patients (41.5%) were symptomatic. Their mean age was 54 (range 32–74) years old; 61% were female, and their mean body mass index was 25.4. Nineteen (76%) out of 25 women had previously been pregnant, with an average of 3.6 pregnancies per woman. CONCLUSIONS The frequency of cholelithiasis was similar to that reported in the literature for the general population. However, the high frequency of symptomatic patients points toward an indication of routine pre-transplant cholecystectomy to avoid serious post-transplant complications. PMID:20454496

    There is lack of knowledge to what degree clinical/morphological presentation and course of IgA nephropathy (IgAN) prior to end-stage renal disease are risk factors for graft loss after kidney transplantation. Patients with IgAN between 1988 and 2006 (registered in the Norwegian Kidney Biopsy Registry) who later received a kidney transplant (registered in the Norwegian Renal Registry) were included. The cohort was followed up regarding death-censored graft loss throughout 2008. Graft survival with a rapid progressive (RP) vs. a slow progressive (SP) course of pre-Tx IgAN (annual GFR > or <30 mL/min/1.73 m(2) ) was studied. Among 106 included patients, there were 14 graft losses giving a graft loss rate of 1.9/100 patient years. Follow-up until the first kidney transplant was 6.9 ± 4.4 (range 0.1-19) yr. Patients with pre-Tx RP had a higher graft loss rate compared with SP patients (6.3 vs.1.3/100 patient years, p < 0.001). Graft loss rate with living-related donor (LRD) was similar to unrelated donor (UD) grafts. Most RP patients had received LRD grafts, and in SP patients, graft survival with LRD grafts was better than UD grafts (0.3 vs.2.1/100 patient years, p = 0.055). A rapid pre-transplant course is a strong risk factor for transplant failure in patients with IgAN. © 2011 John Wiley & Sons A/S.

    Pediatric ventricular assist device (VAD) support as bridge to transplant has improved waitlist survival, but the effects of pre-implant status and VAD-related events on post-transplant outcomes have not been assessed. This study is a linkage analysis between the PediMACS and Pediatric Heart Transplant Study databases to determine the effects of VAD course on post-transplant outcomes. Database linkage between October 1, 2012 and December 31, 2015 identified 147 transplanted VAD patients, the primary study group. The comparison cohort was composed of 630 PHTS patients without pre-transplant VAD support. The primary outcome was post-transplant survival, with secondary outcomes of post-transplant length of stay, freedom from infection and freedom from rejection. At implant, the VAD cohort was INTERMACS Profile 1 in 33 (23%), Profile 2 in 89 (63%) and Profile 3 in 14 (10%) patients. The VAD cohort was older, larger, and less likely to have congenital heart disease (p < 0.0001). However, they had greater requirements for inotrope and ventilator support and increased liver and renal dysfunction (p < 0.0001), both of which normalized at transplant after device support. Importantly, there were no differences in 1-year post-transplant survival (96% vs 93%, p = 0.3), freedom from infection (81% vs 79%, p = 0.9) or freedom from rejection (71% vs 74%, p = 0.87) between cohorts. Pediatric VAD patients have post-transplant outcomes equal to that of medically supported patients, despite greater pre-implant illness severity. Post-transplant survival, hospital length of stay, infection and rejection were not affected by patient acuity at VAD implantation or VAD-related complications. Therefore, VAD as bridge to transplant mitigates severity of illness in children. Copyright © 2017 International Society for the Heart and Lung Transplantation. Published by Elsevier Inc.

    Sudden unexplained anuria in renal transplant patients could well be secondary to occult internal hemorrhage rather than the usual vascular thrombotic or obstructive event, even in the completely stable patient. Urgent intervention in such bleeding states can save patient's life and graft function. Graft survival is very exceptional in graft artery or vein thrombosis. Contrary to hemorrhagic events, life is usually not threatened by thrombotic events involving the renal graft vasculature. We present here three unfortunate cases that shared the problem of unexpected anuria due to a hemorrhagic event in apparently stable renal transplant patients. (author)

    The aim of the current study was to compare results in pediatric renal transplantation of patients with and without SBP. Between 2001 and 2013, a total of 168 kidney transplants were performed at our center. A retrospective analysis was performed and recipients were divided into two groups: NB and SBP. Incidence of surgical complications after procedure, and graft and patient survival were evaluated. A total of 155 recipients (92%) with complete data were analyzed, and 13 recipients that had had previous bladder surgeries were excluded (11 with VUR surgery and two with previous kidney transplants), of the 155 recipients: 123 (79%) patients had NB, and 32 (21%) patients had SBP, with a median follow-up of 60 (1-137) and 52 (1-144) months, respectively. Among post-transplant complications, UTI (68.8% vs. 23%, p < 0.0001) and symptomatic VUR to the graft (40.6% vs. 7.3%, p < 0.0001) were significantly higher in the SBP group. There was no significant difference in overall graft and patient survival between groups. Renal transplantation is safe in pediatric recipients with SBP; however, urologic complications such as UTI and VUR were significantly higher in this group. Graft and patient survival was similar in SBP and NB groups. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Background Every year, thirty-five thousand patients receive renal transplants worldwide. Kidney transplant provides better quality of life and reduced morbidity. Doppler and sonography were the best imaging modalities for evaluation. Aims To assess the sonographic findings of renal allograft and to determine the correlation between Doppler resistive index and size of allograft and echogenicity. Methods This was a cross-sectional study conducted in Khartoum State from January to August 2016. A total of 86 patients with known transplanted kidneys were scanned with ultrasound using 3MHz and 5MHz transducers. The age was categorized into four groups and so the Doppler indices. Descriptive statistics used to analyse quantitative and qualitative variables (percent and means ± SD. Spearman's rho test was used to find the correlation between RI of renal vessels and allograft size. The Qui-square test was used to find an association between RI and echogenicity of the graft. Results Renal transplantation was common at the age of 20 to 50 years. The mean Doppler index of the renal artery was 0.68±0.11 in renal allografts. Renal transplantation was common in professionals and homemakers (30.2 per cent and 20.93 per cent respectively. Hypertension and diabetes were the most common causes (44.1 per cent and 18.6 per cent. A significant correlation was found between RI and allograft size (p-value=0.012. There was no statistical association between RI and echogenicity of allograft (pvalue=0.106. Conclusion The Doppler resistive index is significantly correlated with allograft size and had no association with echogenicity. Patients with enlarged allograft had raised resistive indices. The study recommended that Duplex ultrasound should be used in the initial assessment and follow-up of renal transplant.

    Mycophenolate sodium (EC-MPS) has been shown to be as effective and as safe as mycophenolate mofetil (MMF) in renal transplant patients. Nevertheless, compared to MMF its use in liver transplant patients has been limited. The purpose of this study was to analyze the efficacy of EC-MPS as a primary immunosuppressant or as a replacement for MMF in liver transplant patients. Ninety among 470 liver transplant recipients were receiving or had added an antimetabolite to their immunosuppressant therapy. The most common reason for this change was renal dysfunction (47.8%) or diabetes (32.2%). EC-MPS was started at a median of 30 months after liver transplantation. The mean administered daily dose was 720 mg/d. At least one gastrointestinal symptom was reported by 25 patients. Abdominal pain (16.6%) and diarrhea (14.5%) were the most frequent. EC-MPS had to be discontinued in two patients, while six others required dose reduction to resolve the symptoms. Hematological adverse events were infrequent: three patients had leukopenia and one, anemia, all of which responded to dosage reduction. There was a creatinine reduction within 6 months of drug commencement and maintenance of the lower creatinine levels at 1 year among patients who began EC-MPS for renal dysfunction. Serum low-density lipoprotein cholesterol and triglyceride levels were significantly lower among patients on EC-MPS than on MMF. In conclusion, EC-MPS appears to have a similar efficacy and safety profile as MMF in liver transplant patients. Hematological and gastrointestinal adverse events were infrequent; seldom had the drug to be discontinued.

  14. Steroid withdrawal in renal transplant patients: the Irish experience.

    Phelan, P J

    2012-02-01

    BACKGROUND: Steroid therapy is associated with significant morbidity in renal transplant recipients. However, there is concern that steroid withdrawal will adversely affect outcome. METHODS: We report on 241 renal transplant recipients on different doses of corticosteroids at 3 months (zero, <\\/= 5 mg\\/day, > 5 mg\\/day). Parameters analysed included blood pressure, lipid profile, weight change, new onset diabetes after transplantation (NODAT), allograft survival and acute rejection. RESULTS: Elimination of corticosteroids had no impact on allograft survival at 1 year. There were no cases of NODAT in the steroid withdrawal group compared with over 7% in each of the steroid groups. There were no significant improvements in weight gain, blood pressure control or total cholesterol with withdrawal of steroids before 3 months. CONCLUSIONS: In renal transplant patients treated with tacrolimus and mycophenolate, early withdrawal of steroids does not appear to adversely affect allograft outcome at 1 year. It may result in less NODAT.

    Full Text Available Introduction: Heart transplant in Spain is a frequent and raising technique with big personal, social and financial impact to those who get involved. However, the corporeity analysis, although it is a key constituent element in the integral definition of the human being, is poorly approached in the process.Objective: This work seeks to analyse the heart transplanted patient’s own corporeity perception through himself/herself as well as through his/her closest relatives.Method: We will approach the study from the phenomenological paradigm consisting of fully describing the lived experiences as well as the consequent perceptions in order to obtain a holistic and deep knowledge of reality. So that we will make a descriptive research work with qualitative approach. Sound recorded open interviews will be carried out to fellows who had been heart transplanted in Transplants Unit of Puerta de Hierro Hospital in Madrid. Initial informants’ selection criteria will be:1. Older than eighteen years old patients who had been heart transplanted within the last two years.2. Interviews to relatives who normally live together with the transplanted patients. Individual and social perception o corporeity from each subject will be analysed as well as that perception in function of genre. Data will be obtained from the interviews generated information and they will be analysed through the qualitative technique called “speech analysis”.

    There are no European recommendations on issues specifically related to lung transplantation (LTX) in cystic fibrosis (CF). The main goal of this paper is to provide CF care team members with clinically relevant CF-specific information on all aspects of LTX, highlighting areas of consensus and controversy throughout Europe. Bilateral lung transplantation has been shown to be an important therapeutic option for end-stage CF pulmonary disease. Transplant function and patient survival after transplantation are better than in most other indications for this procedure. Attention though has to be paid to pretransplant morbidity, time for referral, evaluation, indication, and contraindication in children and in adults. This review makes extensive use of specific evidence in the field of lung transplantation in CF patients and addresses all issues of practical importance. The requirements of pre-, peri-, and postoperative management are discussed in detail including bridging to transplant and postoperative complications, immune suppression, chronic allograft dysfunction, infection, and malignancies being the most important. Among the contributors to this guiding information are 19 members of the ECORN-CF project and other experts. The document is endorsed by the European Cystic Fibrosis Society and sponsored by the Christiane Herzog Foundation. PMID:24800072

  20. Computational models for the study of heart-lung interactions in mammals.

    Science.gov (United States)

    Ben-Tal, Alona

    2012-01-01

    The operation and regulation of the lungs and the heart are closely related. This is evident when examining the anatomy within the thorax cavity, in the brainstem and in the aortic and carotid arteries where chemoreceptors and baroreceptors, which provide feedback affecting the regulation of both organs, are concentrated. This is also evident in phenomena such as respiratory sinus arrhythmia where the heart rate increases during inspiration and decreases during expiration, in other types of synchronization between the heart and the lungs known as cardioventilatory coupling and in the association between heart failure and sleep apnea where breathing is interrupted periodically by periods of no-breathing. The full implication and physiological significance of the cardiorespiratory coupling under normal, pathological, or extreme physiological conditions are still unknown and are subject to ongoing investigation both experimentally and theoretically using mathematical models. This article reviews mathematical models that take heart-lung interactions into account. The main ideas behind low dimensional, phenomenological models for the study of the heart-lung synchronization and sleep apnea are described first. Higher dimensions, physiology-based models are described next. These models can vary widely in detail and scope and are characterized by the way the heart-lung interaction is taken into account: via gas exchange, via the central nervous system, via the mechanical interactions, and via time delays. The article emphasizes the need for the integration of the different sources of heart-lung coupling as well as the different mathematical approaches. Copyright © 2011 Wiley Periodicals, Inc.

    Osteoporosis is common in liver transplant recipients as a result of both iatrogenic factors and preexisting hepatic osteodystrophy. To assess the prevalences of osteoporosis and fractures and to identify risk factors for these two abnormalities in patients awaiting liver transplantation for end-stage liver disease. Between January 2006 and December 2007, patients on a liver transplant waiting list underwent a routine evaluation comprising the identification of risk factors for osteoporosis, radiographs of the spine, bone mineral density measurements (BMD), and laboratory tests (phosphate and calcium levels, hormone assays, liver function tests, and bone turnover markers). We studied 99 patients (70 males and 20 females; mean age, 55 ± 8 years) including 75% with alcohol-induced cirrhosis with or without hepatocarcinoma. Among them, 36% had radiographic vertebral fractures, 38% had osteoporosis, 35% had osteopenia, and 88% had vitamin D insufficiency or deficiency (25(OH)vitamin D3bone resorption markers correlated negatively with BMD at the spine and hip. The Model for End-Stage Liver Disease score correlated negatively with hip BMD. Our findings suggest high prevalences of low BMD values and vertebral fractures among patients awaiting liver transplantation. Bone status should be evaluated routinely in candidates to liver transplantation. Copyright © 2011 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

    2013-05-01

    Full Text Available Background/Aims: Patients with a failed kidney transplant represent a unique, high-risk chronic kidney disease population that is increasing in number, and may be sub-optimally managed. Our aim was to compare the survival of patients with failed allografts to patients with native kidney failure and to assess whether their survival is affected by the graft resection. Methods: Kaplan-Meier and Cox-regression survival analyses were performed on the data of 57 patients with graft failure and of 123 transplant-naive haemodialysed patients. Results: After adjustment for age and gender, there was no statistically significant difference in the mortality of patients in the two groups. The 43 patients, who had a transplanted kidney nephrectomy had a statistically not significant survival benefit over non-nephrectomised patients (age and gender adjusted hazard ratio: 0.56 95 % confidence interval: 0.24-1.58, p-value: 0.18. Conclusion: Elective graft resection is a safe, effective alternative for both the treatment and the prevention of the chronic inflammatory state associated with a failed kidney transplant.

    Early treatment failure (ETF) in follicular lymphoma (FL), defined as relapse or progression within 2 years of frontline chemoimmunotherapy, is a newly recognized marker of poor survival and identifies a high-risk group of patients with an expected 5-year overall survival (OS) rate of approximately 50%. Transplantation is an established option for relapsed FL, but its efficacy in this specific ETF FL population has not been previously evaluated. This study compared autologous hematopoietic stem cell transplantation (auto-HCT) with either matched sibling donor (MSD) or matched unrelated donor (MUD) allogeneic hematopoietic cell transplantation (allo-HCT) as the first transplantation approach for patients with ETF FL (age ≥ 18 years) undergoing auto-HCT or allo-HCT between 2002 and 2014. The primary endpoint was OS. The secondary endpoints were progression-free survival, relapse, and nonrelapse mortality (NRM). Four hundred forty FL patients had ETF (auto-HCT, 240; MSD hematopoietic stem cell transplantation [HCT], 105; and MUD HCT, 95). With a median follow-up of 69 to 73 months, the adjusted probability of 5-year OS was significantly higher after auto-HCT (70%) or MSD HCT (73%) versus MUD HCT (49%; P = .0008). The 5-year adjusted probability of NRM was significantly lower for auto-HCT (5%) versus MSD (17%) or MUD HCT (33%; P ETF, undergoing auto-HCT for FL have low NRM and a promising 5-year OS rate (70%). MSD HCT has lower relapse rates than auto-HCT but similar OS. Cancer 2018. © 2018 American Cancer Society. © 2018 American Cancer Society.

    Purpose: To assess the value of functional magnetic resonance urography for the noninvasive postoperative evaluation of renal transplants. Methods: A saturation inversion projection sequence allows the selective imaging of strongly T1 weighted signal from the MR contrast agent. A coronal slab leads to images comparable to conventional urography which can be acquired as a sequence with four images per minute. Results: 15 patients with urologic questionable findings after renal transplantation were studied. FMRU revealed in 6 patients normal findings, in 6 moderate dilatation of the renal pelvis without any urodynamic relevant obstruction. 3 pathologic findings, ureteral leak, ureteropelvic-junction obstruction and ureteral stenosis were diagnosed and consequently surgically treated. The imaging quality in all studies was diagnostic and urologically relevant. Conclusion: FMRU can be used as a noninvasive technique for the assessment of renal transplant in cases with suspicion of complication in the excretory system. (orig.) [de

    HIV infection has experienced dramatic improvement in morbidity and mortality with the highly active antiretroviral therapy (HAART). This prompted a reevaluation of organ-solid transplantation as a treatment option for HIV-infected patients. Some trials in the United States have shown that one- and 2-year graft and patient survival is comparable to HIV-negative transplant population. In Europe the experience is still scarce. The aim of this study is to analyse the outcome and the clinical characteristics of HIV-infected patients who received kidney transplantation in Spain in the HAART era. Ten patients were transplanted in our country since 2001. Only one patient was black. The main cause of end-stage renal disease reported was glomerulonephritis. Six of the recipients were coinfected by hepatitis C virus. Inclusion criteria included undetectable HIV viral load and CD4 counts greater than 200/pL. Immunosuppression consisted of steroids, tacrolimus and mycophenolate mofetil, with antibody induction in 4 cases. The median and mean follow-up was 11 and 16.3+/-15.6 (3-46) months, respectively. One recipient lost his graft because of early renal venous thrombosis. The remaining patients are functioning graft with mean serum creatinina level of 1.5 +/- 0.5 mg/dl. Biopsy-proven acute rejection was diagnosed in 4 recipients and was reversed in all cases with antirejection treatment. The plasma HIV RNA levels have remained controlled and CD4 counts have been stable in excess of 200 cell/microL. None of patients have developed AIDS complications. Recipients receiving protease inhibitor-based HAART regimens required significant dosing modification to maintain appropriate tacrolimus levels. Our results show that renal transplantation can be a safe and effective treatment in select HIV-infected patients. Like other series, the acute rejection rate was higher than in non-HIV recipients. The reasons of this rejection incidence remain unknown.

There is currently a lack of evidence regarding the self-reported concerns of SCT patients before and after SCT.Aim and design: This exploratory study performed a secondary analysis of self-reported, written concerns of SCT patients before and after transplant to determine patients' concerns.Methods: Content analysis of text box entries of SCT patients collected between 2005 and 2007 at the Seattle Cancer Care Alliance. Text box entries were collected as part of symptom assessment using the Electronic Self-Report Assessment – Cancer instrument. The assessment was presented to 137 patients undergoing SCT at two time points: prior to ambulatory visits before any therapy had begun (T1 and at the first visit after hospital discharge following SCT (T2.Results: Text box entries were made before (n = 52 and after (n = 87 the transplant, resulting in 139 text box entries made by 137 patients representing 133 concerns. Using content analysis, the entries were categorized and ranked according to frequency. After symptom concerns, patients ranked work and financial issues the most frequent concerns prior to SCT. After SCT, symptoms remained the most frequently entered area of concern, followed by survival.Conclusion: Oncology providers need to assess SCT patients for work and financial concerns before and after transplant. Appropriate and timely referrals may ease the burden of these concerns for patients. Thus, assessment of financial and work concerns by the oncology team should be an integral part of quality health care for patients undergoing SCT.Keywords: self-report, electronic

    Congenital heart disease (CHD) is the most common birth defect, affecting about 0.8% of live births. Advances in recent decades have allowed >85% of children with CHD to survive to adulthood, creating a growing population of adults with CHD. Little information exists regarding survival, demographics, late outcomes, and comorbidities in this emerging group, and multiple barriers impede research in adult CHD (ACHD). The National Heart, Lung, and Blood Institute and the Adult Congenital Heart Association convened a multidisciplinary Working Group to identify high-impact research questions in ACHD. This report summarizes the meeting discussions in the broad areas of CHD-related heart failure, vascular disease and multisystem complications. High-priority subtopics identified included heart failure in tetralogy of Fallot, mechanical circulatory support/transplantation, sudden cardiac death, vascular outcomes in coarctation of the aorta, late outcomes in single ventricle disease, cognitive and psychiatric issues, and pregnancy.

    Full Text Available Abstract Background There is a relative lack of recent information about late post kidney transplantation anaemia (PTA, especially in the developing countries; data are scarce about the prevalence and risk factors of PTA. Sudan was a leading country in Africa and Arab world in kidney transplantation. The first kidney transplantation in Sudan was in 1973. Methods This is a cross-sectional hospital analytic study enrolling all kidney transplanted recipients following in the transplant referral clinics at Ahmed Gassim, Selma and Ibn Sina Hospitals, Khartoum/Sudan, in the period from 1/8/2010 to 1/9/2010, clinical and laboratory data were obtained from 114 patients, anaemia was defined as Hb levels of Results The study showed that 39.5% of the patients were anaemic. Univariate analysis showed that late PTA is significantly associated with not using Erythropoietin (EPO in the pre-transplant period (p = Conclusion The study concluded that late PTA is common and under recognized. Risk factors for late PTA include renal dysfunction, history of rejection, longer duration of transplantation and not using EPO in the pre-transplant period. Renal dysfunction and not using EPO in the pre-transplant period are major predictors of late PTA.

    Sirolimus (SR) is a lipophilic macrocytic lactone with immunosuppressive properties (mTOR inhibitor) commonly used in solid organ transplantation and recently introduced in the prophylaxis and treatment of graft-versus-host disease. Its numerous side effects include: hyperlipidemia, arthralgias, noncardiac peripheral edema, thrombotic microangiopathy and interstitial pneumonitis. SR-associated pneumonitis is a rare but potentially serious complication due to its increasing utilization in transplant patients. We report the case of a patient undergoing hematopoietic stem cell transplantation with severe respiratory distress and SR therapy. Microbiological tests were all negative and other complications related to transplantation were discarded. The chest computed tomography of high-resolution showed pneumonitis. The SR therapy was interrupted and treatment was started with steroids with resolution of symptoms. SR associated pneumonitis is a potentially fatal side effect. In patients treated with SR and respiratory failure, we must suspect this complication because early recognition along with drug discontinuation and steroid treatment is essential to reverse this complication.

From these, 84 were transplanted, and 62 finished the study; 20 with FAP and 42 with Liver Disease (LD. These patients were assessed before, and 12 months after, transplantation. The patients that remained waiting for transplantation originated the control group. First, transplanted (study group and non-transplanted (control group patients were compared regardless of their diagnosis, and then only FAP patients were compared between both groups.Results12 months after transplantation the score on the Quality of Life’s Physical and Mental Component of the SF-36 was significantly higher in transplanted versus non-transplanted patients (concerning the whole group FAP and LD patients. However, significant differences were only found for the Quality of Life’s Physical Component subscale between both FAP groups (study and control group.ConclusionIn sum, liver transplantation does not have a significant impact in FAP patients’ Mental Quality of Life score. One possible reason to this is the fail in acquiring adaptive coping strategies after transplantation.

    The postoperative chest radiographic findings in 38 patients undergoing orthotopic (37 patients) and heterotopic (1 patient) cardiac transplantation were evaluated. Findings were correlated with those of echocardiograms, sputum and blood cultures, and lung and heart biopsies. The radiographic manifestations in the chest of these patients are classified in the following three main categories: 1) newly formed cardiac silhouette findings due to the transplanted heart itself, i.e., changes in size and shape of the new heart and pericardial effusion resulting from the placement of a smaller heart in a larger pericardial sac. 2) infectious complications due to bacteria, fungal, and other opportunistic agents secondary to immunosuppressive therapy, and 3) usual postoperatice complications following thoracomoty and open-heart surgery.

    Results: It was determined that the hemodialysis patients responding to the survey were in the 20-95 age group with an average age of 58,64±15,64 years. 87,9% of the patients reported that they had been briefed about kidney transplants, 32,2% of those had been briefed said that the information had been delivered by the dialysis physician, 77,7% stated that they wanted a kidney transplant from a cadaver, 49,5% did not want a kidney transplant from a live donor and 35,5% indicated that the national organ transplant system operated adequately. Furthermore, it was noted that 50,9% of the responders were registered on the waiting lists of kidney transplant centers. Conclusions: It was concluded that it is necessary to provide sufficient information to hemodialysis patients about kidney transplants and the national organ transplant system to steer them to transplant centers. It is anticipated that the results of this study will assist officers of the Ministry of Health, politicians involved in health issues, decision makers and health professionals.

    Full Text Available BACKGROUND Renal transplantation is a successful therapy for patients with end-stage kidney disease. In a country like India, where tuberculosis is highly prevalent, it poses immense diagnostic challenge. Proper knowledge about the microbiological spectrum would help to start appropriate therapy empirically, awaiting confirmation. The aim of the study is to study the microbiological profile of lower respiratory tract infections in renal transplant recipients. MATERIALS AND METHODS Consecutive patients who presented to the transplant clinic with cardinal respiratory symptoms and fever were screened radiologically and an attempt to make a microbiological diagnosis was done with sputum or bronchial wash wherever needed. Setting- Prospective observational study conducted in the Department of Nephrology, Transplant Clinic, Rajiv Gandhi Government General Hospital and Madras Medical College. Post-renal transplant patients were followed up for 2 years between October 2014 - October 2016 and the development of pulmonary infection and the number of episodes were systematically recorded. RESULTS A total of 32 episodes of pulmonary infections were observed in 29 patients (23 males and 6 females. Bronchial wash had higher diagnostic yield than sputum. Triple drug immunosuppression comprising cyclosporine, prednisolone and azathioprine (75.8% and episodes of acute graft rejection requiring pulse methylprednisolone (37.93% were important prerequisites for developing pulmonary infection. Pseudomonas 12 (3%, Klebsiella 8 (25% and Mycobacterium tuberculosis 8 (25% were the most common organisms recovered. CONCLUSION Aggressive diagnostic modalities should be carried out for establishing the diagnosis. Empirical regimens should cover for Pseudomonas and Klebsiella. Tuberculosis should be sought for keenly. Mixed infections were also common in the study.

    Full Text Available Aspergillus pericarditis is a rare and life-threatening infection in immunosuppressed patients. It has nonspecific clinical manifestations that often mimic other disease entities especially in patients who have extensive comorbidities. Diagnosis is oftentimes delayed and rarely done antemortem. A high degree of suspicion in immunocompromised patients is necessary for evaluation and timely diagnosis. This is a case of Aspergillus pericarditis with cardiac tamponade in a renal transplant patient with liver cirrhosis. Two months after transplant, he developed decompensation of his cirrhosis from hepatitis C, acute cellular rejection, and Kluyvera bacteremia, followed by vancomycin-resistant Enterococcus faecium (VRE bacteremia. Four months after transplant, the patient presented with lethargy and fluid overload. He subsequently developed shock and ventilator-dependent respiratory failure. An echocardiogram showed pericardial effusion with cardiac tamponade. He had emergent pericardiocentesis that showed purulent drainage. He was started on broad-spectrum antibiotics. Amphotericin B was initiated when the pericardial fluid grew mold that was later identified as Aspergillus fumigatus. The patient quickly decompensated and expired.

    Between February 1981 and December 1984 we treated 52 patients with chronic myeloid leukemia in the chronic phase and 18 patients with more advanced disease by high-dose chemoradiotherapy followed by allogeneic bone marrow transplantation using marrow cells from HLA-identical sibling donors. In addition, the 40 patients who had not previously undergone splenectomy received radiotherapy to the spleen. To prevent graft versus host disease, cyclosporine was given either alone or in conjunction with donor marrow depleted of T cells. Of the 52 patients treated in the chronic phase, 38 are alive after a median follow-up of 25 months (range, 7 to 50); the actuarial survival at two years was 72%, and the actuarial risk of relapse was 7%. Of the 18 patients with more advanced disease, 4 have survived; the actuarial two-year survival was 18%, and the actuarial risk of relapse was 42%. We conclude that the probability of cure is highest if transplantation is performed while the patient remains in the chronic phase of chronic myeloid leukemia. T-cell depletion may have reduced the incidence and severity of graft versus host disease. The value of irradiation to the spleen before transplantation has not been established

  11. Implication of thymoglobulin in kidney transplant patients: review article

    Sudabeh Alatab

    2015-11-01

    Full Text Available Thymoglobulin is a purified polyclonal immunoglobulin that has been used widely over the last decades in the prevention and treatment of rejection following renal transplantation. This immunoglobulin works against human thymocytes. Since thymoglobulin does not contain the nephrotoxic properties therefore it can be used in induction therapy especially in patients with higher risk of graft rejection such as patients who receive graft from cadavers. Recent research showed also its beneficial role in cross-match-positive transplantation, a role that is mediated through conjunction with inhibitors of terminal complement activation. This immunoglobulin has also been used for treatment of rejection following renal transplantation. Thymoglobulin can have various effects on various Immune system cells including T cells, B cells and also plasma cells. Thymoglobulin also affects the Tcell surface antigens, natural killer-cell antigens, B cell antigens, plasma cell antigens, adhesion molecules and chemokine receptors. Diverse effects of thymoglobulin on the immune system includes: T cell depletion, induce apoptosis in B cell lineage and interference with dendritic cell functional properties. Thymoglobulin can cause acute complications, delayed complications as well as infectious complications. Acute reaction events includes: anaphylaxis, fever, chills, dyspnea, nausea, vomiting and diarrhea. Thymoglobulin also induces cytokine release syndrome manifested by high grade fevers and chills and treated by steroid therapy. Delayed reactions events usually present as serum sickness and infections. Infectious complications are more important and include cytomegalovirus (CMV infection, sepsis, candidiasis, herpes simplex and urinary infections. Thymoglobulin can also induce cytokine release syndrome. It has been thought that thymoglobulin increases the risk of post-transplant lymphoproliferative disorder (PTLD, however, debate still exists whether such an

    Full Text Available Muslims with renal transplant often ask their doctors whether fasting Ramadan is safe. Scanty studies have addressed this question. This prospective study was undertaken to identify any clinical or biological changes with Muslim fasting. 22 kidney transplant patients with stable kidney functions, who were transplanted for more than one year, and voluntarily chose to fast during Ramadan in 1425 H (October-November 2004, were studied. Total of 22 subjects (10 men and 12 women with a mean age of 47 ± 11.6 years were studied. Full clinical and biological assessment was done before during and after the month of Ramadan fasting. Medications were taken in two divided doses at sunset (time of breaking the fast and pre dawn (before the fast. None of the patients experienced any undue fatigue, or symptoms. Body weight, blood pressure, kidney function tests, blood sugar, lipid profile, and cyclosporine levels remained stable. In conclusion it is safe for renal transplant recipients of more than one year and having stable graft function to fast during the month of Ramadan; however caution is advised for moderate to severe impaired renal function.

    Full Text Available Objective to evaluate the prevalence of Staphylococcus aureus nasal colonization in renal transplant patients and to identify the related risk factors. Method Swabs were used to collect nasal samples from 160 patients who had undergone a transplant within the previous year at the Kidney and Hypertension Hospital. The ‘National Committee for Clinical Laboratory Standards’ norms were followed for the collection, isolation, identification and sensitivity measurements. Results There was a 9.4% (15 prevalence of Staphylococcus aureus nasal colonization, of which one (6.7% was resistant to oxacillin. It was possible to identify as an associated risk factor a wait of more than one year for accessing dialysis prior to the transplant (p=0.029. Conclusion Given the high morbidity and mortality rates that this microorganism causes in the target population, other studies should be carried out, and pre- and post-transplant screening should occur in order to develop strategies that improve the prevention and control of the spread of Staphylococcus aureus.

    2009-01-01

    The incidence of primary central nervous system lymphoma (PCNSL) has increased during the past 40 years. This has been associated with immunodeficiency, mainly in patients infected with the human immunodeficiency virus (HIV) and in transplant patients. Tumor genesis is related with the Epstein-Barr virus (EBV). The most frequent PCNSL immuno phenotype is B-cell lymphoma. Clinical manifestations depend on tumor localization, and are usually behavior dysfunctions and intracranial hypertension syndrome. Differential diagnosis must take into consideration infectious processes, stroke, primary brain tumors, and metastases. The diagnosis of PCNSL requires brain MRI and brain biopsy. It is important to assess HIV infection when diagnosing PCNSL. This review reports a case of primary brain lymphoma in a patient who underwent renal transplantation due to polycystic kidney disease 8 years before.

    Kidney transplantation is the preferred treatment option for end-stage kidney disease. However, transplantation is not a cure and the prospective recipient needs to carefully evaluate the risks and benefits of receiving a transplant before agreeing to have the transplant. The objective of this commentary is to demonstrate that many kidney transplant recipients have unrealistic expectations of what life after transplantation involves. After monitoring participants in a randomised controlled trial through the first 12 months post-transplantation, we question whether patients understood the impact of receiving a transplant. In our study, participants were not prepared for the considerable time and effort involved in adhering to their medications. Participants felt challenged by the constant hospital, pathology and pharmacy visits; they were fearful that their transplant could reject; and they struggled with adapting to their new way of living. This paper offers new insights into understanding the life of patients post transplantation and the challenges of informing patients about the consequences of kidney transplantation. Understanding the challenges faced by new transplant recipients can help health professionals educate patients about life post-transplantation so patients have a genuine understanding of what they are consenting to, which is likely to enhance medication adherence and ultimately, graft success.

INTRODUCTION: Lung transplantation, which was initially described as an experimental method in 1963, has become a therapeutic option for patients with advanced pulmonary diseases due to improvements in organ conservation, surgical technique, immunosuppressive therapy and treatment of post-operative infections. METHODS: We retrospectively reviewed the records of the 39 patients who received lung transplantation in our institution between August 2003 and August 2006. Twenty-nine patients survived one year post-transplantation, and all of them were followed. RESULTS: The increase in lung function in the double-lung transplant group was more substantial than that of the single-lung transplant group, exhibiting a statistical difference from the 1st month in both the forced expiratory volume in one second (FEV1 and the forced vital capacity (FVC in comparison to the pre-transplant values (p <0.05. Comparison between double-lung transplant and single lung-transplant groups of emphysema patients demonstrated a significant difference in lung function beginning in the 3rd month after transplantation. DISCUSSION: The analyses of the whole group of transplant recipients and the sub-group of emphysema patients suggest the superiority of bilateral transplant over the unilateral alternative. Although the pre-transplant values of lung function were worse in the double-lung group, this difference was no longer significant in the subsequent months after surgery. CONCLUSION: Although both groups demonstrated functional improvement after transplantation, there was a clear tendency to greater improvement in FVC and FEV1 in the bilateral transplant group. Among our subjects, double-lung transplantation improved lung function.

    A therapeutic and effective doctor-patient relationship and patient-doctor relationship is at the core of all successful medical care. The medical and psychological evaluation of a potential kidney donor serves to protect the long-term health of both the donor and the potential recipient. Careful assessment of risk and donor education is at the core of donor evaluation and the decision to progress with donation requires refined clinical judgment by the medical team and critical thinking by the donor. Increasing pressure to increase the numbers of living donor transplants and suggestions by some that the process should be commercialized make it timely to consider the nature of the relationship between the doctor and the patient in the unusual circumstance of living donation. A high rate of complications in recipients of purchased kidneys and a lack of knowledge of the fate of paid donors have been reported. Commercialization of transplantation undermines the therapeutic doctor-patient relationship and threatens the healthy development of the international transplant endeavor.

    Bartter syndrome (BS) is a clinically and genetically heterogeneous inherited renal tube disorder characterized by renal salt wasting, hypokalemic metabolic alkalosis and normotensive hyperreninemic hyperaldosteronism. There have been several case reports of BS complicated by focal segmental glomerulosclerosis (FSGS). Here, we have reported the case of a BS patient who developed FSGS and subsequent end-stage renal disease (ESRD) and provided a brief literature review. The patient presented with classic BS at 3 months of age and developed proteinuria at 7 years. Renal biopsy performed at 11 years of age revealed a FSGS perihilar variant. Hemodialysis was initiated at 11 years of age, and kidney transplantation was performed at 16 years of age. The post-transplantation course has been uneventful for more than 3 years with complete disappearance of BS without the recurrence of FSGS. Genetic study revealed a homozygous p.Trp(TGG)610Stop(TGA) mutation in the CLCNKB gene. In summary, BS may be complicated by secondary FSGS due to the adaptive response to chronic salt-losing nephropathy, and FSGS may progress to ESRD in some patients. Renal transplantation in patients with BS and ESRD results in complete remission of BS. PMID:21359059

    Full Text Available Still's disease (SD is a multisystemic inflammatory disease characterized by persistent arthritis and in many cases with fever of unknown origin. Diagnosis of SD is challenging because of nonspecific characteristics and especially in the case of a patient with solid organ transplantation and immunosuppressive therapy where multiple causes of fever are possible. There is no diagnostic test for SD, even though some useful diagnostic criteria or laboratory findings, such as serum ferritin levels, have been proposed, and useful imaging studies for the diagnosis or followup of SD have not been developed. We report the case of a 9-year-old child who presented with high grade fever associated with joint pain after a history of liver transplantation and immunosuppressive therapy. Laboratory tests showed increased acute phase reactants, elevated ferritin, and leukocytosis. An 18 F-fluorodeoxyglucose positron emission tomography (18F-FDG PET was performed identifying abnormal hypermetabolic areas localized in spleen, transplanted liver, and bone marrow secondary to inflammatory process. All infectious, autoimmune, and malignant causes were ruled out. A diagnosis of SD was performed and a steroid-based regimen was initiated with adequate response and no evidence of recurrence. To our knowledge this is the first case of SD following a solid organ transplant.

    BACKGROUND: Steroid therapy is associated with significant morbidity in renal transplant recipients. However, there is concern that steroid withdrawal will adversely affect outcome. METHODS: We report on 241 renal transplant recipients on different doses of corticosteroids at 3 months (zero, ≤5 mg\\/day, >5 mg\\/day). Parameters analysed included blood pressure, lipid profile, weight change, new onset diabetes after transplantation (NODAT), allograft survival and acute rejection. RESULTS: Elimination of corticosteroids had no impact on allograft survival at 1 year. There were no cases of NODAT in the steroid withdrawal group compared with over 7% in each of the steroid groups. There were no significant improvements in weight gain, blood pressure control or total cholesterol with withdrawal of steroids before 3 months. CONCLUSIONS: In renal transplant patients treated with tacrolimus and mycophenolate, early withdrawal of steroids does not appear to adversely affect allograft outcome at 1 year. It may result in less NODAT.

    Full Text Available Invasive aspergillosis is a serious complication in renal transplant recipients. Hepatic involvement, although seen in liver transplant recipients, has not been reported following renal transplantation. We describe here an interesting occurrence of hepatic Aspergillus infection in a renal transplant recipient. The infection responded to anti-fungal therapy, but there was re-activation following a second renal transplant. In addition, the patient had recurrence of the underlying membrano-proliferative glomerulonephritis following both transplants. The relevant existing literature relating to these problems has been reviewed.

    2010-05-01

    Composite tissue allograft (CTA) is defined as heterologous transplantation of a complex comprising skin and subcutaneous, neurovascular and mesenchymal tissue. Such techniques allow complex reconstruction using matched tissue, without donor site morbidity. The potential indications in orthopaedics-traumatology could in the future be more frequent than the present indications of heart, lung, liver, kidney and pancreas transplantation. International clinical experience clearly demonstrates the feasibility of CTA, both surgically and immunologically. However, immunosuppression remains indispensable, exposing the patient to risks that are not acceptable for purely functional surgery, except in very particular indications. The main hope for the future lies in induction of graft-specific tolerance. Copyright 2010 Elsevier Masson SAS. All rights reserved.

Investigators have long researched the ways in which cardiopulmonary bypass may insult the human body. Potential solutions arose and laid the groundwork for development of safer postoperative care strategies.Conclusion:Steady progress has been made in cardiopulmonary bypass in the decades since it was first conceived of by Gibbon. Despite the constant evolution of cardiopulmonary bypass techniques and attempts to minimize their complications, it is still essential that clinicians respect the particularities of each patient's physiological function.

    Current adherence to dietary recommendations for chronic kidney disease was evaluated in kidney transplant patients in the maintenance phase. A total of 268 maintenance phase kidney transplant patients were included in the study. Estimated daily intakes of oral protein and salt were calculated from 24-h urinary excretion of nitrogen and sodium, respectively. Dietary recommendations for chronic kidney disease, as issued in 2014 by the Japanese Society of Nephrology, were used as the basis for assessing diet. The study included 114 female patients and 154 male patients. The mean age, posttransplantation years, body mass index, estimated glomerular filtration rate, and 24-h urinary excretion of protein were 56.3 years, 11.2 years, 22.0 kg/m(2), 42.6 mL/min/1.73 m(2), and 321 mg/d, respectively. Estimated daily protein and salt intakes were 0.98 ± 0.26 g/kg/d and 9.3 ± 3.9 g/d. Only 47 patients (17.5%) in the case of salt intake and 105 patients (39.2%) in the case of protein intake were within reference values. The 24-h urinary protein excretion of the daily salt intake-adherent group (adherence rate to dietary recommendations for chronic kidney disease in kidney transplant patients was low. The 24-h urinary protein excretion of the daily salt intake-adherent group was significantly less than that of the nonadherent group. Dietary therapy for these patients may have the potential to improve kidney graft function and survival. Copyright © 2016 Elsevier Inc. All rights reserved.

    Extracorporeal life support (ECLS) is a well-established technique for the treatment of different cardiac and pulmonary diseases, e.g., congenital heart disease and acute respiratory distress syndrome. Additionally, severely ill patients who cannot be weaned from the heart-lung machine directly after surgery have to be put on ECLS for further therapy. Although both systems include identical components, a seamless transition is not possible yet. The adaption of the circuit to the patients' size and demand is limited owing to the components available. The project I³-Assist aims at a novel concept for extracorporeal circulation. To better match the patient's therapeutic demand of support, an individual number of one-size oxygenators and heat exchangers will be combined. A seamless transition between cardiopulmonary bypass and ECLS will be possible as well as the exchange of components during therapy to enhance circuit maintenance throughout long-term support. Until today, a novel oxygenator and heat exchanger along with a simplified manufacturing protocol have been established. The first layouts of the unit to allow the spill- and bubble-free connection and disconnection of modules as well as improved cannulas and a rotational pump are investigated using computational fluid dynamics. Tests were performed according to current guidelines in vitro and in vivo. The test results show the feasibility and potential of the concept.

    Many patients receiving cyclosporine (CSA) develop hepatic dysfunction or pancreatitis. The authors reviewed 106 records of cardiac transplant patients maintained on CSA. Eleven patients underwent 16 hepatobiliary scans (HBSs) for abdominal pain and/or abnormal liver function. Of 16 HBSs, ten demonstrated normal gallbladder visualization. Follow-up in all cases confirmed scan findings. Five patients had no gallbladder visualization; confirmation of acute cholecystitis was obtained by surgery in two and by autopsy in three. One patient had previous cholecystectomy. The authors found HPS useful for evaluating acute cholecystitis in patients receiving CSA with or without associated drug-related pancreatitis and hepatic insufficiency and suggest that HBS can assist in the selection of patients for CSA dose adjustment

    To overcome the shortage of appropriate-sized whole liver grafts for children, technical variant liver transplantation has been practiced for decades. We perform a meta-analysis to compare the survival rates and incidence of surgical complications between pediatric whole liver transplantation and technical variant liver transplantation. To identify relevant studies up to January 2014, we searched PubMed/Medline, Embase, and Cochrane library databases. The primary outcomes measured were patient and graft survival rates, and the secondary outcomes were the incidence of surgical complications. The outcomes were pooled using a fixed-effects model or random-effects model. The one-year, three-year, five-year patient survival rates and one-year, three-year graft survival rates were significantly higher in whole liver transplantation than technical variant liver transplantation (OR = 1.62, 1.90, 1.65, 1.78, and 1.62, respectively, ptechnical variant liver transplantation. Continuing efforts should be made to minimize surgical complications to improve the outcomes of technical variant liver transplantation.

    Lung transplantation is a widely accepted treatment for patients with end-stage lung disease related to idiopathic pulmonary fibrosis (IPF). However, there are conflicting data on whether double lung transplant (DLT) or single lung transplant (SLT) is the superior therapy in these patients. The purpose of this study was to determine whether actuarial post-transplant graft survival among IPF patients concurrently listed for DLT and SLT is greater for recipients undergoing the former or the latter. The United Network for Organ Sharing provided de-identified patient-level data. Analysis included lung transplant candidates with IPF listed between January 1, 2001 and December 31, 2009 (n = 3,411). The study population included 1,001 (29.3%) lung transplant recipients concurrently listed for DLT and SLT, all ≥18 years of age. The primary outcome measure was actuarial post-transplant graft survival, expressed in years. Among the study population, 433 (43.26%) recipients underwent SLT and 568 (56.74%) recipients underwent DLT. The analysis included 2,722.5 years at risk, with median graft survival of 5.31 years. On univariate (p = 0.317) and multivariate (p = 0.415) regression analyses, there was no difference in graft survival between DLT and SLT. Among IPF recipients concurrently listed for DLT and SLT, there is no statistical difference in actuarial graft survival between recipients undergoing DLT vs SLT. This analysis suggests that increased use of SLT for IPF patients may increase the availability of organs to other candidates, and thus increase the net benefit of these organs, without measurably compromising outcomes.

    Full Text Available CONTEXT: Most patients subjected to liver transplantation presents hypersplenism, which is reversed after the operation. However, some patients remain with moderate to intense hypersplenism. OBJECTIVES: To study the effect of liver transplantation on platelet count in patients with hypersplenism. METHOD: Of a total of 233 patients who underwent liver transplantation, 162 were excluded from the present study because of occurrence of steroid-resistant rejection, absence of hypersplenism before the transplantation, absence of follow-up for at least 2 years or incomplete exams data. The electronic study protocols of the remaining 71 patients were reviewed to determine the demographics, etiology of cirrhosis, and results of pathologic examination of the explanted liver. Serial platelet count was obtained from the study protocol on the day before liver transplantation and 1, 2, 4, and 6 months and 1 year after liver transplantation. Statistical analysis was performed using the Student's t-test, chi-square test, and Spearman's correlation test. RESULTS: Posttransplant platelet count at all time intervals was significantly higher than the pretransplant value (P100,000/mm³ in 58 patients (81.7% 1 month after liver transplantation. Twelve patients (16.9% remained with thrombocytopenia 1 year after liver transplantation. Three patients (4.2% had recurrence of thrombocytopenia within 1 year after liver transplantation. There was no correlation between pretransplant platelet count and the Child-Pugh class or the MELD score. CONCLUSION: Liver transplantation reverses hypersplenism in most patients.

    Hematopoietic cell transplantation (HCT) is performed in select centers in the United States (U.S.), and patients are often required to temporarily relocate to receive care. The purpose of this study was to identify housing barriers impacting access to HCT and potential solutions. A mixed-methods primary study of HCT social workers was conducted to learn about patient housing challenges and solutions in place that help address those barriers. Three telephone focus groups were conducted with adult and pediatric transplant social workers (n = 15). Focus group results informed the design of a national survey. The online survey was e-mailed to a primary social worker contact at 133 adult and pediatric transplant centers in the U.S. Transplant centers were classified based on the patient population cared for by the social worker. The survey response rate was 49%. Among adult programs (n = 45), 93% of centers had patients that had to relocate closer to the transplant center to proceed with HCT. The most common type of housing option offered was discounted hotel rates. Among pediatric programs (n = 20), 90% of centers had patients that had to relocate closer to the transplant center to proceed with HCT. Ronald McDonald House was the most common option available. This study is the first to explore housing challenges faced by patients undergoing HCT in the U.S. from the perspective of social workers and to highlight solutions that centers use. Transplant centers will benefit from this knowledge by learning about options for addressing housing barriers for their patients.

    Operationally tolerant patients (TOL) display a higher number of blood B cells and transcriptional B cell signature. As they rarely develop an allo-immune response, they could display an abnormal B cell differentiation. We used an in vitro culture system to explore T-dependent differentiation of B cells into plasma cells. B cell phenotype, apoptosis, proliferation, cytokine, immunoglobulin production and markers of differentiation were followed in blood of these patients. Tolerant recipients show a higher frequency of CD20(+) CD24(hi) CD38(hi) transitional and CD20(+) CD38(lo) CD24(lo) naïve B cells compared to patients with stable graft function, correlating with a decreased frequency of CD20(-) CD38(+) CD138(+) differentiated plasma cells, suggestive of abnormal B cell differentiation. B cells from TOL proliferate normally but produce more IL-10. In addition, B cells from tolerant recipients exhibit a defective expression of factors of the end step of differentiation into plasma cells and show a higher propensity for cell death apoptosis compared to patients with stable graft function. This in vitro profile is consistent with down-regulation of B cell differentiation genes and anti-apoptotic B cell genes in these patients in vivo. These data suggest that a balance between B cells producing IL-10 and a deficiency in plasma cells may encourage an environment favorable to the tolerance maintenance. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

  18. [Changes in the transplantation world--from altruism to a utilitarian approach].

    Science.gov (United States)

    Mor, Eytan

    2006-10-01

    The lack of organs for transplantation is a worldwide problem that has created a moral conflict between the traditional altruistic basis of organ donation and alternative solutions based on utilitarian grounds. Survival of grafts achieved in recent decades after unrelated living-donor kidney transplantation between spouses is longer than with deceased donor transplantation. This experience justified the extension of kidney donation beyond the traditional close family relationships including: anonymous donors and paired exchange programs. However, unrelated donation of kidneys within altruistic norms could not provide an ultimate solution for the lack of organs for transplantation. On the other hand, globalization and development of advanced medical technology in developing countries that do not provide transplantation for all their citizens, created an opportunity for a worldwide flourish of transplant tourism as an alternative solution for transplant candidates. Transplant tourism functions according to market laws and is profit-driven, as opposed to the legal organ exchange programs in Europe and the U.S.A., which are non-profit and patient-oriented. The transition from trade in kidneys from unrelated living-donors to the use of other organs (heart, lung and liver) from death penalty prisoners in China was only a matter of deciding where to lay the moral border when justifying the act for the sake of life-saving. Considering the inability of current legal altruistic transplantation practice to supply the growing need for organs, healthcare authorities and professional transplantation organizations have to tackle the donor crisis by designing legally acceptable utilitarian solutions. For instance, through the formation of international organ exchange programs under formal agreements or, in the case of kidney transplantation, through the establishment of a regulated compensated donation system.

    Cytomegalovirus (CMV) infection is an important contributor to the morbidity and mortality associated with bone marrow transplantation (BMT). Infection may lead to CMV disease involving multiple organs such as pneumonia, gastroenteritis, retinitis, central nervus system involvement and others. CMV seropositivity is an important risk factor and approximately half of BMT recipients will develop clinically significant infection most commonly in the first 100 d post-transplant. The commonly used tests to diagnose CMV infection in these patients include the pp65 antigenemia test and the CMV DNA polymerase chain reaction (PCR) assay. Because of its greater sensitivity and lesser turnaround time, the CMV PCR is nowadays the preferred test and serves as a main guide for pre-emptive therapy. Methods of CMV prevention include use of blood products from seronegative donors or leukodepleted products. Prophylaxis or pre-emptive therapy strategies for CMV prevention may be used post-transplant with the latter becoming more common. The commonly used antivirals for pre-emptive therapy and CMV disease management include intravenous gancyclovir and foscarnet. The role of intravenous immunoglobulin, although used commonly in CMV pneumonia is not clear.

    Despite a high prevalence of sleep disruption among hematopoietic cell transplant (HCT) recipients, relatively little research has investigated its relationships with modifiable cognitive or behavioral factors or used actigraphy to characterize sleep disruption in this population. Autologous HCT recipients who were 6-18 months post transplant completed self-report measures of cancer-related distress, fear of cancer recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors upon enrollment. Patients then wore an actigraph for 7 days and completed a self-report measure of sleep disruption on day 7 of the study. Among the 84 participants (age M = 60, 45% female), 41% reported clinically relevant sleep disruption. Examination of actigraph data confirmed that, on average, sleep was disrupted (wake after sleep onset M = 66 min) and sleep efficiency was less than recommended (sleep efficiency M = 78%). Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors were related to self-reported sleep disruption (p valuesdisruption after transplant. Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and maladaptive sleep behaviors are related to self-reported sleep disruption and should be considered targets for cognitive behavioral intervention in this population.

    ABSTRACT Objective: clinically characterizing cornea transplant patients and their distribution according to indicated and post-operative conditions of cornea transplantation, as well as estimating the average waiting time. Method: a cross-sectional, descriptive and analytical study performed for all cornea transplants performed at a reference service (n=258). Data were analyzed using Statistical Package for the Social Sciences, version 20.0. Results: the main indicator for cornea transplant was keratoconus. The mean waiting time for the transplant was approximately 5 months and 3 weeks for elective transplants and 9 days for urgent cases. An association between the type of corneal disorder with gender, age, previous surgery, eye classification, glaucoma and anterior graft failure were found. Conclusion: keratoconus was the main indicator for cornea transplant. Factors such as age, previous corneal graft failure (retransplantation), glaucoma, cases of surgeries prior to cornea transplant (especially cataract surgery) may be related to the onset corneal endothelium disorders.

    Heme-Oxygenase-1 catalyzes hemoglobin into bilirubin, iron, and carbon monoxide, a well known vasodilator. Heme-Oxygenase-1 expression and carbon monoxide production as measured by blood carboxyhemoglobin levels, increase in end stage liver disease patients. We hypothesized that there may be a correlation between carboxyhemoglobin level and early graft function in patients undergoing liver transplant surgeries. In a descriptive retrospective study, 39 patients who underwent liver transplantation between the year 2005 and 2006 at KFSH&RC, are included in the study. All patients received general anesthesia with isoflurane in 50% oxygen and air. Levels of oxyhemoglobin, carboxyhemoglobin and methemoglobin concentration in percentage were recorded at preoperative time, anhepatic phase, end of surgery, ICU admission and 24 hr after surgery. The level of lactic acid, prothrombin time (PT), partial thrombin time (PTT), serum total bilirubin and ammonia were also recorded at ICU admission and 24 hr after surgery. The numbers of blood units transfused were recorded. 39 patients were included in the study with 13/39 for living donor liver transplant (LDLT) compared to 26/39 patients scheduled for deceased donor liver transplant (DDLT). The mean age was 35.9 +/- 16.9 years while the mean body weight was 60.3 +/- 20.9 Kg. Female to male ratio was 21/18. The median packed red blood cell (PRBC) units was 4 (Rang 0-40). There was a significant increase in carboxyhemoglobin level during the anhepatic phase, end of surgery and on ICU admission compared with preoperative value (pcarboxyhemoglobin level on ICU admission and 24 hrs postoperatively were positively correlated with the changes in serum total bilirubin and prothrombin time (R = 0.35, 0.382, 0.325 and 0.31) respectively pcarboxyhemoglobin concentration and PT and total bilirubin while still the correlation with lactic acid was weak. There was no correlation between average perioperative carboxyhemoglobin concentration

    The thyroid hormones T4, T3, rT3 and TSH were assayed in 134 adult patients evaluated and accepted as potential liver transplant candidates at the University of Pittsburgh from March, 1981 to December, 1983. The subsequent course of these patients was evaluated with respect to the levels of these hormones obtained at the time of acceptance for transplantation. T4 levels were increased significantly while their T3 levels were reduced (both p < 0.01) in those who survived and were discharged home as compared to either those who died waiting to be transplanted or died following the procedure. As a result, the ratio of T3/T4 was reduced markedly (p < 0.01) in those who were transplanted and survived as compared to those not transplanted or dying following transplantation. Importantly, the rT3 levels clearly separated (p < 0.01) those who would die prior to transplantation from those who would survive to be transplanted. Finally, the ratio rT3/T3 even more clearly separates those who will die prior to transplantation (p < 0.01) from the other two groups. These data suggest that thyroid hormone levels, particularly rT3 levels, might be useful in setting priorities for which patients referred for a transplantation evaluation should be accepted into the program and in determining who among accepted patients should be operated upon in preference to others also accepted and waiting to be transplanted.

    Neurologic complications are common after hematopoietic stem cell transplantation (HSCT) and solid organ transplantation (SOT) and affect 30-60% of transplant recipients. The aim of this article is to provide a practical imaging approach based on the timeline and etiology of CNS abnormalities, and neurologic complications related to transplantation of specific organs. The lesions will be classified based upon the interval from HSCT procedure: pre-engraftment period <30 days, early post-engraftment period 30-100 days, late post-engraftment period >100 days, and the interval from SOT procedure: postoperative phase 1-4 weeks, early posttransplant syndromes 1-6 months, late posttransplant syndromes >6 months. Further differentiation will be based on etiology: infections, drug toxicity, metabolic derangements, cerebrovascular complications, and posttransplantation malignancies. In addition, differentiation will be based on complications specific to the type of transplantation: allogeneic and autologous hematopoietic stem cells (HSC), heart, lung, kidney, pancreas, and liver. Thus, in this article we emphasize the strategic role of neuroradiology in the diagnosis and response to treatment by utilizing a methodical approach in the work up of patients with neurologic complications after transplantation.

    Abstract The goals of the National Heart, Lung, and Blood Institute (NHLBI) Center for Fetal Monkey Gene Transfer for Heart, Lung, and Blood Diseases are to conduct gene transfer studies in monkeys to evaluate safety and efficiency; and to provide NHLBI-supported investigators with expertise, resources, and services to actively pursue gene transfer approaches in monkeys in their research programs. NHLBI-supported projects span investigators throughout the United States and have addressed novel approaches to gene delivery; “proof-of-principle”; assessed whether findings in small-animal models could be demonstrated in a primate species; or were conducted to enable new grant or IND submissions. The Center for Fetal Monkey Gene Transfer for Heart, Lung, and Blood Diseases successfully aids the gene therapy community in addressing regulatory barriers, and serves as an effective vehicle for advancing the field.

    The molecular causes of ≈4000 medical conditions have been described, yet only 5% have associated therapies. For decades, the average time for drug development through approval has taken 10 to 20 years. In recent years, the serious challenges that confront the private sector have made it difficult to capitalize on new opportunities presented by advances in genomics and cellular therapies. Current trends are disturbing. Pharmaceutical companies are reducing their investments in research, and biotechnology companies are struggling to obtain venture funds. To support early-stage translation of the discoveries in basic science, the National Institutes of Health and the National Heart, Lung, and Blood Institute have developed new approaches to facilitating the translation of basic discoveries into clinical applications and will continue to develop a variety of programs that create teams of academic investigators and industry partners. The goal of these programs is to maximize the public benefit of investment of taxpayer dollars in biomedical research and to lessen the risk required for industry partners to make substantial investments. This article highlights several examples of National Heart, Lung, and Blood Institute-initiated translational programs and National Institutes of Health translational resources designed to catalyze and enable the earliest stages of the biomedical product development process. The translation of latest discoveries into therapeutic approaches depends on continued federal funding to enhance the early stages of the product development process and to stimulate and catalyze partnerships between academia, industry, and other sources of capital.

    Data are limited on clinical outcomes in patients awaiting heart transplant (HT) with total artificial heart (TAH) infections. We retrospectively reviewed all TAH recipients at our center. TAH infection was classified as definite if a microorganism was isolated in cultures from the exit site or deep tissues around the TAH; as probable in patients without surgical or microbiologic evidence of infection but no other explanation for persistent or recurrent bloodstream infection (BSI); or possible in patients with clinical suspicion and radiographic findings suggestive of TAH infection, but without surgical intervention or microbiologic evidence. From 2012 to 2015, a total of 13 patients received a TAH, with a median age at implantation of 52 years (range: 28-60). TAH infection occurred in nine patients (seven definite, one probable, one possible) a median of 41 days after implant (range: 17-475). The majority of TAH infections were caused by Staphylococcus species. Seven of nine patients underwent HT (four had pre-HT mediastinal washout, and five had positive HT operative cultures). Three patients had an active BSI caused by the same pathogen causing TAH infection at the time of HT, with one developing a post-HT BSI with the same bacteria. No patient developed post-HT surgical site infection caused by the TAH infection pathogen. No deaths among HT recipients were attributed to infection. TAH infection is frequently associated with BSI and mediastinitis and Staphylococcus was the most common pathogen. A multimodal approach of appropriate pre- and post-HT antimicrobial therapy, surgical drainage, and heart transplantation with radical mediastinal debridement was successful in curing infection. © 2017 John Wiley & Sons A/S.

    Infectious complications are, with rejection, the main cause of morbidity and mortality in heart transplantation recipients. Adequate management of these patients requires an adequate knowledge of risk factors, of most common infectious syndromes and of relevant microorganism, as long as of their resistance pattern. Among the first group, we may mention lower respiratory tract infections, mediastinitis and meningitis, and among the microorganisms, Citomegalovirus, Aspergillus and Toxoplasma gondii. The impressive development of diagnostical techniques and of prophylactic and therapeutical possibilities suggest the convenience of a multidisciplinar approach to these complications.

    The disparity between patients awaiting transplantation and available organs forced many patients to go overseas to receive a transplant. Few data concerning overseas transplantation in Korea are available and the Korea Society for Transplantation conducted a survey to evaluate the trend and outcome of overseas transplantation. The survey, conducted on June 2006, included 25 hospitals nationwide that followed up patients after receiving kidney transplant (KT) or liver transplant (LT) overseas. The number of KT increased from 6 in 2001 to 206 in 2005 and for LT from 1 to 261. The information about overseas transplant came mostly from other patients (57%). The mean cost for KT was $21,000 and for LT $47,000. Patients were admitted for 18.5 days for KT and 43.4 days for LT. Graft and patient survival was 96.8% and 96.5% for KT (median follow up 23.1 months). Complication occurred in 42.5% including surgical complication (5.3%), acute rejection (9.7%) and infection (21.5%). Patient survival for LT was 91.8% (median follow up 21.2 months). Complication occurred in 44.7% including 19.4% biliary complication. Overseas KT and LT increased rapidly from 2001 to 2005. Survival of patients and grafts was comparable to domestic organ transplantation, but had a high complication rate.

    The causes of graft loss were analysed in a group of 487 kidney transplants, of which 252 (51.46%) concerned related donors, 139 (28.5%) cadaver donors and 96 (19.7%) non-related donors. A total of 74 kidneys were lost in the first 3 months after transplantation (15.19%). In 34 cases the loss was due to immunological factors (45.9%) in 21 cases (28.3%) to the death of the patients and in 19 cases (25.7%) to the technical causes. From 34 losses by immunological problems, 32 were rejections with humoral character (acute vascular rejection in 11 cases, late humoral rejection in 11 cases, immediate humoral rejection in 9 cases, ABO incompatibility in one case) and recurrence of original disease in one case. Acute cellular rejection was observed in only one patient. None of the patients died from immunological loss of the graft. The most frequent cause of death were sepsis (13 out of 21 patients) and the most common focus of infection was pulmonary (5 patients). It occurred most frequently with cadaveric donor, (10.07%). Death related to cardiovascular causes occurred in four patients, digestive in two and in consequence of arterial bleeding in two. Among the 23 losses by technical factors renal artery thrombosis was the most frequent (11 cases); renal rupture occurred in three cases, renal vein thrombosis in two rupture of arterial anastomosis in one and inviable kidney in another one. The technical loss was most frequent with cadaver donors (8.63%), followed by non-related donors (4.16%) and related donors (2.77%). Four patients died from causes directly related to technical factors.(ABSTRACT TRUNCATED AT 250 WORDS)

  14. Hyperfractionated total body irradiation for bone marrow transplantation. Results in seventy leukemia patients with allogeneic transplants

    1983-01-01

    From May, 1979 to March, 1981, 76 leukemia patients were prepared for bone marrow transplantation (BMT) with a new hyperfractionated total body irradiation (TBI) regimen (1320 cGy in 11 fractions, 3x/day), followed by cyclophosphamide, 60 mg/kg, for two days. Partial lung shielding was done on each treatment, with supplemental electron beam treatments of the chest wall to compensate, and of the testes, a sanctuary site. This regimen was initiated to potentially reduce fatal interstitial pneumonitis as well as decrease leukemic relapse. Overall actuarial survival at 1 year for acute non-lymphocytic leukemia (ANLL) patients is 63%, while relapse-free survival at 1 year is 53%. On the other hand, for acute lymphocytic leukemia (ALL) patients, there is no significant difference between relapse or remission patients with regard to overall survival or relapse-free survival, when relapse is defined as > 5% blasts in the marrow at the time of cytoreduction. Overall actuarial survival at 1 year for ALL is 61% and relapse-free survival is 45% at 1 year. Fatal interstitial pneumonitis has dropped to 18% compared with 50% in our previous single-dose TBI regimen (1000 cGy), in which the same doses of cyclophosphamide were given prior to TBI. In conclusion, not only has fatal interstitial pneumonitis been reduced by hyperfractionation and partial lung blocking, but there may be a survival advantage in ALL patients in relapse, who have a survival equal to that of remission patients. This may indicate a greater cell kill with the higher dose (1320 cGy) attained with this regimen, in these patients with a higher leukemic cell burden

    The accumulation of /sup 99m/technetium sulfur colloid (/sup 99m/TcSC) was evaluated in 47 studies performed on 19 renal transplant patients by comparing its transplant activity to its bone marrow accumulation. There was a diagnosis of rejection in 21 of 22 studies (96.5 percent) in which marked transplant accumulation was noted. In 11 studies of patients with a clinical diagnosis of post-transplant acute tubular necrosis (ATN), the transplant activity varied from none to moderate. Rejection developed in 5 of 6 studies with minimal to moderate accumulation. Normally functioning renal transplant patients, or those with ATN and no superimposed rejection, do not show evidence of /sup 99m/TcSC accumulation

    Since 2005, the Lung Allocation Score (LAS) has prioritized patient benefit and post-transplant survival, reducing waitlist to transplant time to fibrosis (CF) and pulmonary fibrosis (PF). We analyzed the times from transplant eligibility to referral, work-up and waitlisting using Kaplan-Meier curves and log-rank tests. Overall, the referral rate for transplant-eligible patients was 64%. Of those referred, approximately 36% reach the lung transplant waitlist. Referred CF patients were significantly more likely to reach the transplant waitlist than PF patients (CF 60% vs PF 22%, p < 0.05). In addition, CF patients had a shorter wait from transplant eligibility to waitlist than PF patients (329 vs 2,369 days, respectively [25th percentile], p < 0.05). Patients with PF and CF both faced delays from eligibility to referral and waitlist. Quality improvement efforts are needed to better identify and refer appropriate patients for lung transplant evaluation. Targeted interventions may facilitate more efficient evaluation completion and waitlist appearance. Copyright © 2017 International Society for Heart and Lung Transplantation.

    Lung transplantation provides a viable option for survival of end-stage respiratory disease. In addition to prolonging survival, there is considerable interest in improving patient-related outcomes such as transplant recipients' symptom experiences. A prospective, repeated measures design was used to describe the symptom experience of 85 lung transplant recipients between 2000 and 2005. The transplant symptom inventory was administered before and at one, three, six, nine, and 12 months post-transplant. Ridit analysis provided a unique method for describing symptom experiences and changes. After lung transplantation, significant (p<0.05) improvements were reported for the most frequently occurring and most distressing pre-transplant symptoms (e.g., shortness of breath with activity). Marked increases in the frequency and distress of new symptoms such as tremors were also reported. Patterns of symptom frequency and distress varied with time since transplant. The findings provide data-based information that can be used to inform pre- and post-transplant patient education and also help caregivers anticipate a general time frame for symptom changes to prevent or minimize symptoms and their associated distress. In addition, symptoms are described, using an innovative method of illustration which shows "at-a-glance" change or lack of change in patients' symptoms from pre- to post-lung transplant. © 2012 John Wiley & Sons A/S.

    Background: More than 40% of patients awaiting a kidney transplant in the UK are sensitised with human leucocyte antigen (HLA) antibodies. Median time to transplantation for such patients is double that of unsensitised patients at about 74 months. Removing antibody to perform an HLA-incompatible (HLAi) living donor transplantation is perceived to be high risk, although patient survival data are limited.

    Over the past 2 decades, significant advances have been made in the management of infections after transplant; however, transplant recipients are still at high risk of infectious complications. This study aimed to evaluate the prevalence of bacterial infections and antimicrobial resistance patterns in kidney transplant recipients. This cross-sectional study included 356 patients who received kidney transplants, regardless of the underlying disease, from 2013 to 2015 at the Montaserieh Transplant Hospital (Mashhad, Iran). Clinical samples collected from patients were sent to the microbiology laboratory for culture processing. Typing of bacteria was conducted, and susceptibility testing was performed according to the Clinical and Laboratory Standards Institute guideline by use the of disk diffusion agar method. Data were then analyzed by SPSS software (SPSS: An IBM Company, IBM Corporation, Armonk, NY, USA) using chi-square test. Among 356 kidney recipients (206 men and 150 women), 115 (32.3%) received transplants from living donors and 241 (67.7%) received transplants from deceased donors. Of 356 total patients, 112 patients (31.5%) had an infection at various times after transplant. The most common gram-negative and gram-positive isolated bacteria were Escherichia coli and coagulase-negative Staphylococcus, with prevalence rates of 66.1% and 48.6%. Most of the isolates were resistant against selected antibiotics. Because of the high prevalence of infection among transplant patients, infection prevention should receive more attention, and antibiotic susceptibility should be determined before treatment.

The rationale is that the C2 correlates best with AUC0-4 (area under the concentration-time curve), which again correlates with rejection and nephrotoxicity. It has also been...... metabolites were added to whole blood from healthy volunteers and the calcineurin phosphatase activity (CaN) was determined.

    Due to impressive improvements in surgical repair options, even patients with complex congenital heart disease (CHD) may survive into adulthood and have a high risk of end-stage heart failure. Thus, the number of patients with CHD needing heart transplantation (HTx) has been increasing in the last decades. This paper summarizes the changing etiology of causes of death in heart failure in CHD. The main reasons, contraindications, and risks of heart transplantation in CHD are discussed and underlined with three case vignettes. Compared to HTx in acquired heart disease, HTx in CHD has an increased risk of perioperative death and rejection. However, outcome of HTx for complex CHD has improved over the past 20 years. Additionally, mechanical support options might decrease the waiting list mortality in the future. The number of patients needing heart-lung transplantation (especially for Eisenmenger's syndrome) has decreased in the last years. Lung transplantation with intracardiac repair of a cardiac defect is another possibility especially for patients with interatrial shunts. Overall, HTx will remain an important treatment option for CHD in the near future. PMID:23577237

    Thrombotic microangiopathy (TMA) is a potentially fatal complication in solid organ and bone marrow transplant patients, with reported incidence of 0.5-3% and mortality of about 75%. To emphasise the importance of early diagnosis and prompt commencement of therapy results in improved clinical outcomes. A retrospective study of all patients who underwent orthotopic liver transplantation (OLTX) at the Western Australian Liver Transplantation Service from May 1994 to December 2010 was conducted to identify patients who developed tacrolimus-induced TMA. We identified four patients with tacrolimus-induced TMA post-OLTX, derived from a cohort of 104 patients treated with tacrolimus in our institution. The mean age at diagnosis was 40 years, and the mean time of onset was 63 ± 7.5 weeks after OLTX. The indications for OLTX in the four patients were fulminant hepatic failure in three (Wilson disease, paracetamol overdose and post-partum thrombotic thrombocytopenic purpura) and hepatitis C virus-related cirrhosis. All patients had tacrolimus post-OLTX. At diagnosis, tacrolimus was discontinued in all patients, and three of the four patients underwent plasma exchange and all patients improved clinically. Mean duration of follow up was 15 ± 7.5 months. There was no mortality 6 months post-TMA. Early diagnosis with immediate discontinuation or conversion of calcineurin inhibitors and plasma exchange should be offered to OLTX patients with TMA as it results in good outcomes. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    Suspected urinary tract obstruction following renal transplantation presents a diagnostic dilemma. The purposes of this study were: (1) to establish a normal range of measurement of output efficiency (OE) in the renal transplant population, and (2) to assess prospectively the usefulness of OE in the setting of allograft obstruction. Twenty-two renal transplant patients with stable renal function and no evidence of hydronephrosis on serial ultrasound examination had a diuretic mercaptoacetyltriglycine scan with calculation of OE. Three renal transplant patients with confirmed graft obstruction were also studied. Standard qualitative and quantitative parameters as well as OE were calculated. The mean OE for the 22 normal renal transplant patients was 86.3%±3.7% (range: 77%-91%). OE values in the three obstructed patients were 59%, 68% and 75% respectively. It is concluded that OE should normally exceed 77% in renal graft recipients. OE is a promising means of diagnosing functional obstruction in these patients. (orig.)

    HLA antibody-incompatible transplantation has a higher risk of rejection when compared to standard renal transplantation. Soluble CD30 (sCD30) has been shown in many, but not all, studies to be a biomarker for risk of rejection in standard renal transplant recipients. We sought to define the value of sCD30 and soluble CD27 (sCD27) in patients receiving HLA antibody-incompatible transplants. Serum taken at different time points from 32 HLA antibody-incompatible transplant recipients was retrospectively assessed for sCD30 and sCD27 levels by enzyme-linked immunosorbent assay (ELISA). This was compared to episodes of acute rejection, post-transplant donor-specific antibody (DSA) levels and 12 month serum creatinine levels. No association was found between sCD27 and sCD30 levels and risk of acute rejection or DSA levels. Higher sCD30 levels at 4-6 weeks post-transplantation were associated with a higher serum creatinine at 12 months. Conclusion patients undergoing HLA antibody-incompatible transplantation are at a high risk of rejection but neither sCD30 (unlike in standard transplantation) nor sCD27 was found to be a risk factor. High sCD30 levels measured at 4-6 weeks post-transplantation was associated with poorer graft function at one year. Copyright © 2010 Elsevier B.V. All rights reserved.

    BACKGROUND: Complications in the biliary tract occur in 5%-30% after liver transplantation and the main part of the complications is successfully managed with endoscopic retrograde cholangiopancreaticography (ERCP). The incidence and risk factors for post-ERCP complications in liver transplantation...... patients are not well described. Our objective was to define the frequency of post-ERCP complications in liver transplantation patients at the Abdominal Center, Rigshospitalet, the only Liver Transplantation Center in Denmark. METHODS: Retrospective study of all ERCPs performed in liver transplantation...... and cholangitis occurred after two procedures, respectively. Multivariate analysis concerning overall complications identified biliary sphincterotomy (p = 0.006) and time since liver transplantation within 90 days postoperatively (p = 0.044) as risk factors for post-ERCP complications. Specifically concerning...

    Mechanical heart-lung interactions are often overlooked in clinical settings. However, their impact on cardiac function can be quite significant. Mechanistic physiology-based models can provide invaluable insights into such cardiorespiratory interactions, which occur not only under external mechanical ventilatory support but in normal physiology as well. In this work, we focus on the cardiac component of a previously developed mathematical model of the human cardiopulmonary system, aiming to improve the model's response to the intrathoracic pressure variations that are associated with the respiratory cycle. Interventricular septum and pericardial membrane are integrated into the existing model. Their effect on the overall cardiac response is explained by means of comparison against simulation results from the original model as well as experimental data from literature.

    Few qualitative studies of simultaneous pancreas-kidney transplantation (SPK Tx) have been published. The aims of this study were to explore from the perspective of patients, the experience of living with diabetes mellitus type 1 (T1DM), suffering from complications, and undergoing SPK Tx with good outcome; and to determine the impact of SPK Tx on patients and their social and cultural environment. We performed a focused ethnographic study. Twenty patients were interviewed. Data were analyzed using content analysis and constant comparison following the method proposed by Miles and Huberman. A functioning SPK Tx allowed renal replacement therapy and insulin to be discontinued. To describe their new situation, patients used words and phrases such as "miracle", "being reborn" or "coming back to life". Although the complications of T1DM, its surgery and treatment, and associated psychological problems did not disappear after SPK Tx, these were minimized when compared with the pretransplantation situation. For patients, SPK Tx represents a recovery of their health and autonomy despite remaining problems associated with the complications of T1DM and SPK Tx. The understanding of patients' existential framework and their experience of disease are key factors for planning new intervention and improvement strategies.

    Full Text Available Today the problem of better life quality of patients with end stage renal disease and after renal transplantation and their sexual adaptation is considered to be more impotent. The clinical part of the investigation is the obser- vation of 205 patients – men with terminal stage renal disease. Erectile dysfunction is represented in 91,4% (64 of patients getting haemodialysis, 92,3% (24 of patients getting peritoneal dialysis, 61,5% (67 of patients after renal transplantation. According to International Index of Erectile Function the mean score of erectile function is 16,7 ± 5,2 in haemodialysis patients, 19,46 ± 3,6 in peritoneal dialysis patients, 21,9 ± 5,6 in patients after renal transplantation. The analysis revealed great prevalence of erectile dysfunction and interest in improvement among the patients with end stage renal disease and after renal transplantation

    To evaluate the efficacy of tailored immunosuppressive regimens prescribed according to a risk stratification scoring system based on the number of HLA mismatches, donor source, panel-reactive antibodies (PRA), and repeat transplant. Patients in a retrospective cohort of 329 kidney transplantations performed from October 2004 to December 2005 were assigned scores of 0, 2, 4, or 6 with higher scores for > or =1 HLA mismatches, PRA > 10%, repeat transplant, and unrelated or deceased donor. Added scores of or = 6 denoted high risk including a CNI-based regimen with an interleukin-2 receptor antibody. The efficacy analysis compared the incidences of biopsy-proven acute rejection episodes (BPAR) at 1 year. Only 227 (69%) of 329 patients had a complete data set and 84 were excluded because they did not follow the prescribed protocol, yielding 113 low- and 30 high-risk patients in the final population. Low-risk patients had a mean PRA of 5.4%, living related donors in 68%, and primary transplants. High-risk patients had a mean PRA of 18.8% (range = 10%-97%), living nonrelated donors in 84%, four deceased donors, and four repeat transplants. The overall 1-year incidence of BPAR was 5.7%. No significant difference (P = .081) was observed in 1-year BPAR between the low- (4.5%) and high-risk (9.8%) groups. Likewise, no significant difference in the 1-year mean serum creatinine was observed according to the CNI. The mean creatinine was 1.12 for cyclosporine and 1.38 for tacrolimus treatment (P = .06) in the low-risk group and 1.08 for cyclosporine and 1.2 for tacrolimus (P = .61) in the high-risk cohort. There was no significant difference in acute rejection rates between the immunologically low- or high-risk patients using tailored immunosuppression, which was effective to minimize its occurrence with good renal function at 1 year.

    Patients with diabetes and end-stage renal failure are known to have a high risk for cardiac morbidity and mortality associated with renal transplantation. The most efficient method to determine preoperative cardiac risk has not been established. To determine the effectiveness of intravenous dipyridamole thallium imaging in predicting cardiac events, 40 diabetic renal transplant candidates were studied preoperatively in a prospective trial. The study group consisted of 40 patients whose average age was 42 years (range 27 to 64); 34 (85%) were hypertensive and 21 (53%) were cigarette smokers. Cardiac history included chest pain in 6 patients and prior myocardial infarction in 3 patients. Dipyridamole thallium imaging showed reversible defects in 9 patients, fixed defects in 8 patients and normal scans in 23 patients. Dipyridamole thallium imaging was performed using 0.56 mg/kg of dipyridamole infused intravenously over 4 minutes. Cardiac events occurred only in patients with reversible thallium defects, of which there were 6. Of these 6 patients, 3 had cardiac events before transplantation and 3 had them in the early postoperative phase (within 6 weeks of surgery). Of 21 patients who underwent renal transplantation, 3 had cardiac events within 6 weeks of transplantation. The average duration of follow-up was 11 months (range 1 to 21). Thus, dipyridamole thallium imaging is an effective method of identifying renal transplant candidates likely to develop cardiac complications. Routine coronary angiography may not be necessary to screen all renal transplant candidates for coronary artery disease before surgery

    Decreased reactivity in mixed lymphocyte culture (MLC) was observed in patients within 1 yr after allogeneic and autologous bone marrow transplantation. Suppressor activity of peripheral blood mononuclear cells (PBMC) from transplant patients was studied by adding these cells as modulator cells to a bidirectional MLC with cells from normal individuals. PBMC from transplant patients markedly suppressed MLC reactivity in a dose-dependent manner. Suppressor activity was present in cells forming rosettes with sheep erythrocytes. Treatment of modulator cells with monoclonal antibodies against T cell differentiation antigens (OKT8, OKIa1) and complement completely abolished suppression of MLC. Suppressor activity was unaffected by 30 Gy irradiation. Suppressor activity declined gradually after transplantation and was inversely correlated with MLC reactivity of each patient at a significant level (p less than 0.01). These observations suggest that OKT8+ Ia+ radioresistant suppressor T cells play a role in the development of decreased MLC reactivity observed during the early post-transplant period

    Objective: To discuss the perioperative nursing norm for patients who are suffering from biliary complications occurred after liver transplantation and who will receive interventional management to treat the complications. Methods: Interventional therapies were performed in 20 patients with biliary complications due to liver transplantation. The interventional procedures performed in 20 cases included percutaneous biliary drainage (n = 13), percutaneous biliary balloon dilatation (n = 5) and biliary stent implantation (n = 7). The clinical results were observed and analyzed. Results: Biliary tract complications occurred after liver transplantation were seen frequently. Proper interventional management could markedly improve the successful rate of liver transplantation and increase the survival rate of the patients. In accordance with the individual condition, proper nursing measures should be taken promptly and effectively. Conclusion: Conscientious and effective nursing can contribute to the early detection of biliary complications and, therefore, to improve the survival rate of both the transplanted liver and the patients.

    Post-transplant diabetes mellitus occurs in 30-50% of cases during the first year post-renal transplantation. It is associated with increased morbidity, mortality and healthcare costs. Risk factors include age and specific immunosuppression regimens. At the same time, renal transplantation is increasingly indicated in elderly (aged >65 years) patients as this proportion of older patients in the prevalent dialysis population has increased. The immune system and β cells undergo senescence and this impacts on the risk for developing post-transplant diabetes and our ability to prevent such development. It may, however, be possible to identify patients at risk of developing post-transplant diabetes, enabling treatment protocols that prevent or reduce the impact of post-transplant diabetes. Much work remains to be completed in this area and is facilitated by the growing base of knowledge regarding the pathophysiology of post-transplant diabetes. Should post-transplant diabetes develop, there are a range of treatment options available. There is increasing interest in using newer agents, although their safety and efficacy in transplant recipients remains to be conclusively established.

    The aim of this study was to investigate the quantity of renal transport blood flow in patients affected by acute tubular necrosis (ATN). During the four years period two hundred and thirty-three studies were performed using {sup 99m}Tc pertechnetate and {sup 131}I - OIH. Renal blood flow was calculated from the first-pass time activity curves generated over the kidney and aorta and expressed as a percentage of cardiac output (RBF/CO). Renal transplant blood flow is clearly diminished in ATN, similar as in acute rejection, and significantly related to the graft function, what means that RBF/CO value could potentially serve as a prognostic factor in the graft function recovery from ATN.

    Patients infected with the human immunodeficiency virus (HIV) have generally been excluded from consideration for liver transplantation. Recent advances in the management and prognosis of these patients suggest that this policy must be reevaluated. To identify the current position of Brazilian transplant centers concerning liver transplantation in asymptomatic HIV-infected patients with end-stage liver disease. A structured questionnaire was submitted by e-mail to Brazilian groups who perform liver transplantation and were active in late 2003, according to the Brazilian Association of Organ Transplantation. Of the 53 active groups, 30 e-mail addresses have been found of professionals working in 41 of these groups. Twenty-one responses (70%) were obtained. Most of the professionals (62%) reported that they do not include HIV-infected patients in waiting lists for transplants, primarily on account of the limited world experience. They also reported, however, that this issue will soon be discussed by the group. Those who accept these patients usually follow the guidelines provided by the literature: patients must fulfill the same inclusion criteria as the other patients with end-stage liver diseases, present low or undetectable HIV viral load, and a CD4 count above 250/mm3. They reported that there are 10 HIV-infected patients in waiting list and that only one patient has received a liver transplant in the country. Most centers do not accept in waiting lists for liver transplantation patients with HIV infection, even asymptomatic ones. However, advances in the management of HIV-infected patients suggest that this policy must be reevaluated. In Brazil, there is practically no experience in liver transplantation in HIV-positive patients.

    Background Successful lung transplantation (LT) for patients with pulmonary fibrosis from telomerase mutations is limited by systemic complications of telomerase dysfunction including myelosuppression, cirrhosis, and malignancy. We describe clinical outcomes among 14 LT recipients with telomerase mutations. Methods Subjects underwent LT between February 2005 and April 2014 at 5 LT centers. We abstracted data from medical records, focusing on outcomes reflecting post-LT treatment effects likely to be complicated by telomerase mutations. Results The median age of subjects was 60.5 years (IQR 52.0–62.0), 64.3% were male, and the mean post-LT observation time was 3.2 years (SD ±2.9). Eleven subjects had a mutation in telomerase reverse transcriptase, 2 in telomerase RNA component, and 1 had an uncharacterized mutation. Ten subjects were leukopenic post-LT; leukopenia prompted cessation of mycophenolate mofetil in 5 and treatment with filgrastim in 4. Six subjects had recurrent lower respiratory tract infections (LRTI), 7 had acute cellular rejection (ACR) (A1), and 4 developed chronic lung allograft dysfunction (CLAD). Ten LT recipients developed chronic renal insufficiency and 8 experienced acute, reversible renal failure. Three developed cancer, none had cirrhosis. Thirteen subjects were alive at data censorship. Conclusions The clinical course for LT recipients with telomerase mutations is complicated by renal disease, leukopenia prompting a change in the immunosuppressive regimen, and recurrent LTRI. In contrast, cirrhosis was absent, ACR was mild, and development of CLAD was comparable to other LT populations. While posing challenges, lung transplantation may be feasible for patients with pulmonary fibrosis due to telomerase mutations. PMID:26169663

    Medical tourism, where patients travel abroad intentionally to access medical treatment, is a growing trend. Some of these patients travel to undergo organ transplantation. This study aims to quantify the number of UK patients who undergo liver transplantation abroad, assessing their motivations and management. Questionnaires were sent to all seven UK liver transplant units enquiring about liver patients receiving transplant abroad. Included were questions on destination, motivation, and pre and post-transplant care. Responses were received from six of the seven transplant centres (86%). A total of 12 patients were identified as having undergone liver transplantation overseas. The top destinations were India, China and Egypt. Four units responded to questions regarding pre-transplant screening. One unit reported Hepatitis B and C screening not taking place. Four units responded to questions regarding post-transplant antimicrobial therapy. This revealed examples of patients inappropriately not receiving valganciclovir, co-trimoxazole, anti-fungal treatment and Hepatitis B immunoglobulins. UK patients are undergoing liver transplant abroad, albeit in small numbers. Pre and post-transplant management of these patients is of a lower standard than that provided to those undergoing transplantation in the UK. Information transfer between overseas and UK based transplant teams is poor. Copyright © 2016 Elsevier Ltd. All rights reserved.

  7. Risk-Adjusted Analysis of Relevant Outcome Drivers for Patients after More Than Two Kidney Transplants

    Directory of Open Access Journals (Sweden)

    Lampros Kousoulas

    2015-01-01

    Full Text Available Renal transplantation is the treatment of choice for patients suffering end-stage renal disease, but as the long-term renal allograft survival is limited, most transplant recipients will face graft loss and will be considered for a retransplantation. The goal of this study was to evaluate the patient and graft survival of the 61 renal transplant recipients after second or subsequent renal transplantation, transplanted in our institution between 1990 and 2010, and to identify risk factors related to inferior outcomes. Actuarial patient survival was 98.3%, 94.8%, and 88.2% after one, three, and five years, respectively. Actuarial graft survival was 86.8%, 80%, and 78.1% after one, three, and five years, respectively. Risk-adjusted analysis revealed that only age at the time of last transplantation had a significant influence on patient survival, whereas graft survival was influenced by multiple immunological and surgical factors, such as the number of HLA mismatches, the type of immunosuppression, the number of surgical complications, need of reoperation, primary graft nonfunction, and acute rejection episodes. In conclusion, third and subsequent renal transplantation constitute a valid therapeutic option, but inferior outcomes should be expected among elderly patients, hyperimmunized recipients, and recipients with multiple operations at the site of last renal transplantation.

    This article addresses a difficult ethical dilemma that transplant surgeons may potentially encounter: whether a patient with a psychiatric illness is a good candidate for a liver transplant. This case study illustrates the challenges involved when considering the ethical principles of patient self-determination, distributive justice of scarce medical resources, "social worth," and protection of vulnerable patient populations. Are patients with psychiatric illness able to provide consent for transplantation? Is it possible to avoid misallocating valuable donor organs and, at the same time, fairly allocate these resources? This article seeks to answer these questions and provide insight into this ethical dilemma.

    Evaluating transplantation grafts at harvest is essential for its success. Laser-induced fluorescence spectroscopy (LIFS) can help monitoring changes in metabolic/structural conditions of tissue during transplantation. The aim of the present study is to correlate LIFSobtained spectra of human hepatic grafts during liver transplantation with post-operative patients' mortality rate and biochemical parameters, establishing a method to exclude nonviable grafts before implantation. Orthotopic liver transplantation, piggyback technique was performed in 15 patients. LIFS was performed under 408nm excitation. Collection was performed immediately after opening donor's abdominal cavity, after cold perfusion, end of back-table period, and 5 min and 1 h after warm perfusion at recipient. Fluorescence information was compared to lactate, creatinine, bilirubin and INR levels and to survival status. LIFS was sensitive to liver changes during transplantation stages. Study-in-progress; initial results indicate correlation between fluorescence and life/death status of patients.

    Different frames of reference can affect one's assessment of the value of hand transplantation. This can result in different yet rational decisions by different groups of individuals, especially patients and physicians. In addition, factors other than frames of reference can affect one's evaluation of hand transplantation, which can result in different decisions.

    The development of food allergy is an increasingly recognized form of morbidity after solid organ transplant. It occurs more commonly in liver transplant recipients, although it has also been reported in heart, lung, kidney, and intestinal transplants. Pediatric transplant recipients are more likely to develop symptoms compared to adults, and reports of frequency vary widely from 5% to 38% in pediatric liver transplant recipients. Multiple mechanisms have been proposed in the literature, although no single mechanism can yet account for all reported observations. As food allergy can have at worst potentially fatal consequences, and at best require lifestyle adjustment through food avoidance, it is important for recipients to be aware of the donor's food allergies and particularly in pediatrics, the possibility of completely de novo allergies. This review explores the recent reports surrounding food allergy after solid organ transplant, including epidemiology, proposed mechanisms, and implications for practice. © 2015 John Wiley & Sons A/S.

    Heart involvement is the leading cause of death of patients with eosinophilic granulomatosis with polyangiitis (EGPA; formerly Churg-Strauss syndrome) and is more frequent in anti-neutrophil cytoplasm antibody (ANCA)-negative patients. Post-transplant outcome has only been reported once. We conducted a retrospective international multicenter study. Patients satisfying the criteria of the American College of Rheumatology and/or revised Chapel Hill Consensus Conference Nomenclature were identified by collaborating vasculitis and transplant specialists, and the help of the Churg-Strauss Syndrome Association. Nine ANCA(-) patients who received transplants between October 1987 and December 2009 were identified. The vasculitis and cardiomyopathy diagnoses were concomitant for 5 patients and separated by 12 to 288 months for the remaining 4 patients. Despite ongoing immunosuppression, histologic examination of 7 (78%) patients' explanted hearts showed histologic patterns suggestive of active vasculitis. The overall 5-year survival rate was low (57%), but rose to 80% when considering only the 6 patients transplanted during the last decade. After survival lasting 3 to 60 months, 4 (44%) patients died sudden deaths. The search for EGPA-related cardiomyopathy is mandatory early in the course of this type of vasculitis. Indeed, prompt treatment with corticosteroids and cyclophosphamide may achieve restore cardiac function. Most patients in this series were undertreated. For patients with refractory EGPA, heart transplantation should be performed, which carries a fair prognosis. No optimal immunosuppressive strategy has yet been identified.

    Aplastic anemia is a rare life-threatening bone marrow failure that is characterized by bicytopenia or pancytopenia in the peripheral blood and a hypoplastic or aplastic bone marrow. The patients are at risk of infection and hemorrhage due to neutropenia and thrombocytopenia and suffer from symptoms of anemia. The main treatment approaches are allogeneic stem cell transplantation and immunosuppression. Here, we review current standard immunosuppression and the attempts that have been made in the past two decades to improve results: review of recent developments also reveals that sometimes not only the advent of new drugs, good ideas and well-designed clinical trials decide the progress in the field but also marketing considerations of pharmaceutical companies. Aplastic anemia experts unfortunately had to face the situation that efficient drugs were withdrawn simply for marketing considerations. We will discuss the current options and challenges in first-line treatment and management of relapsing and refractory patients with an emphasis on adult patients. Some promising new approaches are currently under investigation in prospective, randomized trials.

    Obesity is a relative contraindication to organ transplantation. Preliminary reports suggest that bariatric surgery may be used as a bridge to transplantation in patients who are not eligible for transplantation because of morbid obesity. The Bariatric Center at Tampa General Hospital, University of South Florida, Tampa, Florida. We reviewed the outcomes of 16 consecutive patients on hemodialysis for end-stage renal disease (ESRD) who underwent bariatric surgery from 1998 to 2016. Demographics, comorbidities, weight loss, as well as transplant status were reported. Data is mean ± SD. Six men and ten women aged 43-66 years (median = 54 years) underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 12), laparoscopic adjustable gastric banding (LAGB, n = 3), or laparoscopic sleeve gastrectomy (LSG, n = 1). Preoperative BMI was 48 ± 8 kg/m 2 . Follow-up to date was 1-10 years (median = 2.8 years); postoperative BMI was 31 ± 7 kg/m 2 ; %EBWL was 62 ± 24. Four patients underwent renal transplantation (25%) between 2.5-5 years after bariatric surgery. Five patients are currently listed for transplantation. Five patients were not listed for transplantation due to persistent comorbidities; two of these patients died as a consequence of their comorbidities (12.5%) more than 1 year after bariatric surgery. Two patients were lost to follow-up (12.5%). Bariatric surgery is effective in patients with ESRD and improves access to renal transplantation. Bariatric surgery offers a safe approach to weight loss and improvement in comorbidities in the majority of patients. Referrals of transplant candidates with obesity for bariatric surgery should be considered early in the course of ESRD.

    2006-12-01

    Increased pre- and posttransplantation values of soluble CD30 (sCD30) have been shown to be associated with acute kidney transplant rejection. We sought to study whether high sCD30 could predict rejection early after liver transplantation. The study population included 54 consecutive liver transplant patients, whose samples were collected before liver transplantation and at discharge, which was at a mean time of 3 weeks after transplantation. During the first 6 months posttransplantation, 22 patients experienced an acute rejection episode. Serum sCD30 concentrations were measured by an enzyme-linked immunoassay; changes in serum sCD30 levels posttransplantation were also expressed as relative values compared with pretransplantation results. Liver patients before transplantation displayed higher serum sCD30 values compared with healthy controls: mean values +/- SD were 93 +/- 58 IU/mL vs 17 +/- 8 IU/mL, respectively. At 3 weeks after transplantation the mean sCD30 concentration in liver transplant patients decreased to 59 +/- 42 IU/mL (P = .005). The mean pretransplantation serum sCD30 value was slightly lower among rejecting vs nonrejecting patients: 78 +/- 43 IU/mL vs 104 +/- 65 IU/mL (P = NS). Posttransplantation values in both groups decreased significantly: 47 +/- 34 IU/mL in patients with rejection (P = .014) vs 69 +/- 45 IU/mL in patients without rejection (P = .012). The relative value at 3 weeks posttransplantation decreased slightly more among patients with vs without rejection (70% vs 88%; NS). No correlation was found between serum sCD30 and anti-HLA class I antibodies or crossmatch positivity. In conclusion, neither pre- nor posttransplantation sCD30 levels were associated with acute rejection in liver transplant patients.

    Gingival enlargement frequently occurs in transplant patients receiving immunosuppressive drugs. It was hypothesized that gingival enlargement associated with cyclosporine use results from reduced degradation of extracellular matrix in the gingiva. Matrix metalloproteinase-3 (MMP-3) is involved in biodegradation of the extracellular matrix, and its inhibition may contribute to an abnormal accumulation of fibronectin and proteoglycans, which are MMP-3 substrates. The aim of this study was to investigate whether an association exists between MMP-3 genotypes and gingival enlargement in kidney transplant patients medicated with cyclosporine A. Sixty-four unrelated kidney transplant patients suffering from gingival overgrowth, as well as 111 control transplant patients without gingival overgrowth, were enrolled in the study. Gingival overgrowth was assessed 6 mo after transplantation. During the post-transplant period all patients were given cyclosporine A as a principal immunosuppressive agent. MMP-3 polymorphism was determined using a PCR restriction fragment length polymorphism assay. In kidney transplant patients suffering from gingival overgrowth the mean gingival overgrowth score was 1.35 +/- 0.57, whereas in control subjects the mean gingival overgrowth score was 0.0. The distribution of MMP-3-1178A/dupA alleles among all kidney transplant patients, as well as in the two study subgroups, did not differ significantly from Hardy-Weinberg equilibrium. The frequency of the MMP-3-1171A/A genotype (28.1% for gingival overgrowth vs. 26.1% for controls) and of the MMP-3-1171dupA/dupA genotype (32.8% for gingival overgrowth vs. 22.5% for controls) was similar for both study groups. The risk of gingival overgrowth was lowest among patients carrying the MMP-3-1171A/dupA genotype (odds ratio 0.52), but this did not differ markedly from the other genotypes. No association between MMP-3 gene polymorphism and gingival overgrowth was revealed in kidney transplant patients

    2015-01-01

    Foot and ankle problems are highly prevalent in patients with diabetes mellitus (DM). Increased rates of surgical site infections and noninfectious complications, such as malunion, delayed union, nonunion, and hardware failure, have also been more commonly observed in diabetic patients who undergo foot and ankle surgery. DM is a substantial contributor of perioperative morbidity in patients with solid organ transplantation. To the best of our knowledge, postoperative foot and ankle complications have not been studied in a cohort of diabetic patients who previously underwent solid organ transplantation. The aim of the present study was to evaluate the outcomes of foot and ankle surgery in a cohort of diabetic transplant patients and to compare these outcomes with those of diabetic patients without a history of transplantation. We compared the rates of infectious and noninfectious complications after foot and ankle surgery in 28 diabetic transplant patients and 56 diabetic patients without previous transplantation and calculated the odds ratios (OR) for significant findings. The diabetic transplant patients who underwent foot and ankle surgery in the present cohort were not at an increased risk of overall complications (OR 0.83, 95% confidence interval [CI] 0.33 to 2.08, p = .67), infectious complications (OR 0.54, 95% CI 0.09 to 3.09, p = .49), or noninfectious complications (OR 1.14, 95% CI 0.41 to 3.15, p = .81). Four transplant patients (14.3%) died of non-orthopedic surgery-related events during the follow-up period; however, no deaths occurred in the control group. Diabetic patients with previous solid organ transplantation were not at an increased risk of developing postoperative complications after foot and ankle surgery, despite being immunocompromised. The transplant patients had a greater mortality rate, but their premature death was unrelated to their foot and ankle surgery. Surgeons treating transplant patients can recommend foot and ankle surgery when

    Heart-transplanted patients in Norway undergo annual coronary angiography (CA). The aims of this study were to establish a conversion factor between dose-area product and effective dose for these examinations and to use this to evaluate the accumulated radiation dose and risks associated with annual CA. An experienced cardiac interventionist performed a simulated examination on an Alderson phantom loaded with thermoluminescence dosemeters. The simulated CA examination yielded a dose-area product of 17 Gy cm 2 and an effective dose of 3.4 mSv: the conversion factor between dose-area product and effective dose was 0.20 mSv Gy cm -2 . Dose-area product values from 200 heart-transplanted patients that had undergone 906 CA examinations between 2001 and 2008 were retrieved from the institutional database. Mean dose-area product from annual CA was 25 Gy cm 2 , ranging from 2 to 140 Gy cm 2 . Mean number of CA procedure was 8 (range, 1-23). Mean accumulated effective dose for Norwegian heart-transplanted patients between 2001 and 2008 was 34 mSv (range, 5-113 mSv). Doses and radiation risks for heart-transplanted patients are generally low, because most heart transplantations are performed on middle-aged patients with limited life expectancy. Special concern should however be taken to reduce doses for young heart-transplanted patients who are committed to lifelong follow-up of their transplanted heart. (authors)

We retrospectively reviewed pediatric cases of patients diagnosed with primary immunodeficiencies and scheduled for hematopoietic stem cell transplantation. We identified 22 patients (median age, 6 months; age range, 1 month to 10 years with various diagnoses who received hematopoietic stem cell transplantation. The patient diagnoses included severe combined immunodeficiency (n=11, Chediak-Higashi syndrome (n=2, leukocyte adhesion deficiency (n=2, MHC class 2 deficiency (n=2, chronic granulomatous syndrome (n=2, hemophagocytic lymphohistiocytosis (n=1, Wiskott-Aldrich syndrome (n=1, and Omenn syndrome (n=1. Of the 22 patients, 7 received human leukocyte antigen-matched related hematopoietic stem cell transplantation, 12 received haploidentical hematopoietic stem cell transplantation, and 2 received matched unrelated hematopoietic stem cell transplantation. The results showed that 5 patients had graft failure. Fourteen patients survived, yielding an overall survival rate of 67%. Screening newborn infants for primary immunodeficiency diseases may result in timely administration of hematopoietic stem cell transplantation.

  5. Hypovitaminosis D in patients undergoing kidney transplant: the importance of sunlight exposure

    Directory of Open Access Journals (Sweden)

    Cristiane F. Vilarta

    Full Text Available OBJECTIVES: Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. METHODS: We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits. RESULTS: Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. CONCLUSIONS: Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

    2014-06-01

    Full Text Available To determine the long-term health and function of transplanted dopamine neurons in Parkinson’s disease (PD patients, the expression of dopamine transporters (DATs and mitochondrial morphology were examined in human fetal midbrain cellular transplants. DAT was robustly expressed in transplanted dopamine neuron terminals in the reinnervated host putamen and caudate for at least 14 years after transplantation. The transplanted dopamine neurons showed a healthy and nonatrophied morphology at all time points. Labeling of the mitochondrial outer membrane protein Tom20 and α-synuclein showed a typical cellular pathology in the patients’ own substantia nigra, which was not observed in transplanted dopamine neurons. These results show that the vast majority of transplanted neurons remain healthy for the long term in PD patients, consistent with clinical findings that fetal dopamine neuron transplants maintain function for up to 15–18 years in patients. These findings are critically important for the rational development of stem-cell-based dopamine neuronal replacement therapies for PD.

    Patients with Fontan physiology may eventually require heart transplantation (HT). We determined the rates and outcomes of HT in a national, population-based multicentre study. From 1990 to 2015, 1369 patients underwent the Fontan procedure as recorded in the Australia and New Zealand Fontan Registry. We identified those who underwent HT and analysed their outcomes. We compared rates of HT between two catchment areas. In area 1 (n=721), patients were referred to the national paediatric HT programme or its associated adult programme. In area 2 (n=648), patients were referred to the national paediatric HT programme or one of the other adult HT programmes. Mean follow-up time post-Fontan was 11±8 years. Freedom from Fontan failure was 74%±3.9% at 20 years. HT was performed in 34 patients. Patients living in area 1 were more likely to have HT (4.0%, 29/721 vs 0.8%, 5/648, p<0.001) with a cumulative proportion of 3.4% vs 0.7% at 10 years and 6.8% vs 1.2% at 20 years (p=0.002). Area 1 patients were more likely to undergo HT (hazard ratio 4.7, 95% CI 1.7 to 13.5, p=0.003) on multivariable regression. Post-HT survival at 1, 5 and 10 years was 91%, 78% and 71%, respectively. Compared with other patients with congenital heart disease (n=87), Fontan patients had similar in-hospital outcomes and long-term survival. Although HT after the Fontan procedure can be achieved with excellent outcomes, most patients with Fontan failure do not undergo HT. Significant regional differences in rates of HT in Fontan patients exist. Published by the BMJ Publishing Group Limited.

    Full Text Available Sickle Cell Anaemia (SCA is the most common inherited blood disorder and is associated with severe morbidity and decreased survival. Allogeneic Haematopoietic Stem Cell Transplantation (HSCT is the only curative approach. Nevertheless the decision to perform a marrow transplant includes the risk of major complications  and mortality transplant related. The infections represent the main cause of mortality for SCA patients undergoing transplant. Invasive Pulmonary Aspergillosis (IPA is a devastating opportunistic infection and remains a significant cause of morbidity and mortality in HSCT recipients. Data regarding IPA in the setting of SCA are lacking. In the present report,  we describe a patient with SCA who developed IPA after allogeneic bone marrow transplant. The fungal infection was treated by systemic antifungal therapy in addition to the surgery, despite  mild chronic GVHD and with continuing immunosuppression therapy. This case shows that IPA occurring in bone marrow recipient with SCA can be successful treated

Retrospective chart analysis of HIV-positive patients, who had been liver-transplanted in Germany between July 1997 and July 2011. Results. 38 transplantations were performed in 32 patients at 9 German transplant centres. The reasons for OLT were end-stage liver disease (ESLD and/or liver failure due to hepatitis C (HCV (=19, hepatitis B (HBV (=10, multiple viral infections of the liver (=2 and Budd-Chiari-Syndrome. In July 2011 19/32 (60% of the transplanted patients were still alive with a median survival of 61 months (IQR (interquartile range: 41–86 months. 6 patients had died in the early post-transplantation period from septicaemia (=4, primary graft dysfunction (=1, and intrathoracal hemorrhage (=1. Later on 7 patients had died from septicaemia (=2, delayed graft failure (=2, recurrent HCC (=2, and renal failure (=1. Recurrent HBV infection was efficiently prevented in 11/12 patients; HCV reinfection occurred in all patients and contributed considerably to the overall mortality. Conclusions. Overall OLT is a feasible approach in HIV-infected patients with acceptable survival rates in Germany. Reinfection with HCV still remains a major clinical challenge in HIV/HCV coinfection after OLT.

    Erectile dysfunction can be defined as the persistent inability of man to achieve penile erection and maintain it sufficient for satisfactory coitus. The objectives of this study were to find out the impact of successful renal transplantation on the degree and frequency of erectile dysfunction. Thirty patients of end stage renal disease that were on regular haemodialysis and candidates of renal transplantation of age range 20-55 years were included in the study after getting informed consent. Erectile functions were assessed by history, examination, investigations and international index of erectile function (IIEF) before and 3 and 6 months after renal transplantation, other information regarding disease and patient were collected in the performa. Out of thirty patients 14 (46.6%) patients had sever erectile dysfunction while 16 (53.3%) patients had moderate erectile dysfunction in the pre renal transplantation period. After three months of renal transplantation 15 (50%) had severe erectile dysfunction, 6 (20%) patients moderate erectile dysfunction and 9 (30%) patients mild erectile dysfunction. After six months 11 (36.6%), 10 (33.3%) and 8 (26.6%) patients had severe, moderate and mild erectile dysfunction respectively. There was improvement in 40%, no change in 53.3% and deterioration in 6.6% patients in the erectile functions after getting renal transplantation for end stage renal disease. (author)

    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

    BACKGROUND The Barcelona clinic liver cancer (BCLC) staging system is considered the standard of care for hepatocellular carcinoma (HCC) management. It has various limitations, including lack of second-line treatment options and combination therapy. We prospectively collected data on our HCC patients based on a new decision-making tool (NDT). The objective of this study was to determine the applicability of this tool and compare it with BCLC for treatment allocation, in particular with respect to liver transplantation. MATERIAL AND METHODS We retrospectively reviewed HCC patients who were managed based on an NDT that was developed in 2012. All patients whose treatment decision was based on this tool between 2012 and 2015 were included. Comparison was made with BCLC. Survival was compared for patients who underwent liver transplantation. RESULTS Based on the NDT, 406 (40.6%) patients were eligible for curative treatment versus only 22 (2.2%) patients based on BCLC. A total of 58 (5.8%) patients underwent liver transplant based on the NDT, while only 2 (0.2%) were transplantable based on BCLC. Estimated 3-year survival for transplanted patients based on the NDT was 73%. There were 41 (4.1%) stage C and 15 (1.5%) stage D BCLC patients who received transplant based on the NDT. Estimated 3-year survival for stage A, C, and D BCLC patients who received transplantation was 100%,72%, and 67%, respectively (P=0.6). CONCLUSIONS The NDT correctly identified a group of HCC patients for liver transplantation who would otherwise have received palliative treatment based on the BCLC algorithm.

    To evaluate the value of CT in clarifying the nature of complications after orthopedic liver transplantation, we restrospectively evaluated the files of 88 patients in light of the clinical course and all available diagnostic data. The liver tranplantations were performed in the years 1986 and 1987. As a rule, the examinations comprised of continuous 8 mm-thick CT sections of the abdomen. In the majority of the cases, contrast medium was administered for opacification of the bowel loops, either orally or through a tube. Bowel movement was reduced by intravenous (i.v.) Buscopan. In our series an increase in the periportal hypodensities was found to be an unfavourable prognostic sign. A high percentage of patients with this CT finding subsequently progressed to graft failure due to reasons other than graft rejection. Hence in the final analysis, the CT sign is non-specific and does not permit the definitive diagnosis of graft rejection. Nevertheless, CT is important for excluding conditions that demand surgical intervention, in particular abscess formation. (orig./MG)

    Indium 111( 111 In) labelled autologous platelets were used in the diagnostic observation of patients after renal transplantation. 75 patients were collected in 3 groups of 25 cases each. The first group consisted of patients who were examined during the first 4 weeks after transplantation. Group 2 were patients suffering from histologically proved chronic graft rejection. The 3rd group included cases with good and stable transplant function tested at least 9 months after transplantation. By means of a computerized static study the transplants were examined under the gamma-camera concerning a platelet trapping. Thereby a platelet-uptake-index(PUI) was calculated and compared with the platelet half-life-time (tsub(1/2)). This diagnostic method turned out to be suitable for early diagnosis of acute graft rejection. Hereby the PUI increased from 1.13 +- 0.11 to 1.74 +- 0.17. The further course of rejection episode manifested itself in corresponding changes of PUI. In irreversible rejections the PUI stayed in the high range or increased further. On the other hand reversible graft rejections showed a reduction of PUI, however, in the most cases not to the original basic level. The platelet tsub(1/2) exhibited a strong negative correlation with PUI. Cases suffering from chronic transplant rejection revealed significantly higher platelet trapping by the graft than patients with good and stable transplant function. (Author)

It is a widely used immunosuppressive drug for preventing solid-organ transplant rejection. Compared to cyclosporine, tacrolimus has greater immunosuppressive potency and a lower incidence of side effects. It has been accepted as first-line treatment after liver and kidney transplantation. Tacrolimus has specific features in Chinese transplant patients; its in vivo pharmacokinetics, treatment regimen, dose and administration, and adverse-effect profile are influenced by multiple factors, such as genetics and the spectrum of primary diseases in the Chinese population. We reviewed the clinical experience of tacrolimus use in Chinese liver- and kidney-transplant patients, including the pharmacology of tacrolimus, the immunosuppressive effects of tacrolimus versus cyclosporine, effects of different factors on tacrolimus metabolism on Chinese patients, personalized medicine, clinical safety profile, and patient satisfaction and adherence. This article provides guidance for the rational and efficient use of tacrolimus in Chinese organ-transplant patients.

    This study was carried out to estimate the modification of hydration status within the first three months of renal transplantation. Fifty patients who underwent a first kidney allograft were prospectively followed for three months after renal transplantation to assess hydration status by bioimpedance spectroscopy. Two hours before the transplant procedure, 10/42 (23.8%) patients were overhydrated. Two days after surgery, 32/40 (80.0%) patients were overhydrated and at three months, 14/27 (51.9%) patients remained fluid-overloaded. Peritoneal dialysis (PD) patients had a lower hydration status (-0.60 L) than hemodialysis (HD) patients (0.70 L; p hydration status before transplantation (p = 0.031). At three months, 12/14 of the overhydrated patients had a creatinine clearance between 30 and 60 mL/min/1.73 m(2) . Patients receiving a first kidney transplant frequently have a hydration disorder. Transplantation is associated with increased hydration status, which seems to persist if DGF or SGF occurs. © 2011 John Wiley & Sons A/S.

    Full Text Available This descriptive study explored the quality of life and care needs of Turkish patients who underwent hematopoietic stem cell transplantation. The study sample consisted of 100 hematopoietic stem cell transplant patients. Their quality of life was assessed using Functional Assessment of Cancer Therapy-Bone Marrow Transplant Scale. The mean patient age was 44.99 ± 13.92 years. Changes in sexual functions, loss of hair, loss of taste, loss of appetite, and sleep disturbances were the most common symptoms. The quality of life of transplant patients was moderately affected; the functional well-being and social/family well-being subscales were the most adversely and least negatively affected (12.13 ± 6.88 dimensions, respectively. Being female, being between 50 and 59 years of age, being single, having a chronic disease, and having a history of hospitalization were associated with lower quality of life scores. Interventions to improve functional status, physical well-being, and emotional status of patients during the transplantation process may help patients cope with treatment-related impairments more effectively. Frequent screening and management of patient symptoms in order to help patients adapt to life following allogeneic hematopoietic stem cell transplantation are crucial for meeting care needs and developing strategies to improve their quality of life.

    We performed a survey of United States transplantation centers to evaluate practice patterns in the assessment of nonadherence before and after kidney transplantation. An electronically administered, anonymous survey was sent to 181 United Network for Organ Sharing (UNOS) approved transplantation centers in 2012. Seventy-nine centers completed our survey. Of them, 51.3% had a protocol to evaluate medication/dialysis adherence before the listing; most common (36.4%) was the Simplified Medication Adherence Questionnaire. As an alternative to a questionnaire, the most common measure of nonadherence was the number of missed hemodialysis sessions (77.0%). The most common reason for poor adherence to dialysis regimens was difficulty with transportation (81.3%). Also, 94.4% noted the lack of a questionnaire to evaluate adherence to medications but relied on drug levels (73.4%) and self report. Only 12.9% used a questionnaire for the measurement of quality of life (Karnofsky performance scale). Of the participating centers, 27.1% used a formal cognitive testing for potential living donors. A social worker was used by most centers for nonadherent patients. Respondents indicated that patients (in the pretransplantation state) were more compliant with dialysis than with medication regimens. Finally, 37.7% of respondents noted graft failure due to medication nonadherence in 15% to 29% of their patients. There was a significant variability in the methods of screening for nonadherence while the patient was on dialysis, during pretransplantation work up, and during post-transplantation follow-up examinations. We recommend that there should be a standardized technique to evaluate nonadherence to facilitate focused clinical trials to improve adherence. Copyright © 2014 Elsevier Inc. All rights reserved.

    Patients travel worldwide for paid kidney transplants. Although transplantations abroad are not always illegal, they are commonly perceived to be illegal and unethical involving risks. We aimed to describe the motivations and experiences of patients who traveled abroad for paid kidney transplantations and to examine how these transplantations were facilitated. We interviewed 22 patients who traveled from Macedonia/Kosovo, the Netherlands, and Sweden for paid kidney transplantations between years 2000 and 2009. Patients traveled because of inadequate transplant activity in their domestic countries and dialysis-related complaints. However, 6 patients underwent preemptive transplantations. Cultural factors such as patients' affinity with destination countries, feelings of being discriminated against by the health-care system, and family ties also help explain why patients travel abroad. Seven of the 22 patients went to their country of origin. They were able to organize their transplantations by arranging help from family and friends abroad who provided contacts of caregivers there and who helped cover the costs of their transplants. The costs varied from €5000 to €45 000 (US$6800-US$61 200). Seven patients paid the hospital, 5 paid their doctor, 4 paid a broker, and 6 paid their donors. Research should include interviews with brokers, transplant professionals, and other facilitators to achieve a full picture of illegally performed transplantations.

    Full Text Available ABSTRACTIntroduction:The success of kidney transplantation depends on prevention of organ rejection by the recipient’s immune system, which recognizes alloantigens present in transplanted tissue. Human leukocyte antigen (HLA typing is one of the tests used in pre-renal transplantation and represents one of the most important factors for a successful procedure.Objective:The present study evaluated creatinine and cytokines plasma levels in kidney transplant patients according to pre-transplant HLA typing.Methods:We assessed 40 renal transplanted patients selected in two transplant centers in Belo Horizonte (MG.Results:Patients were distributed into three groups according to HLA compatibility and, through statistical analysis, the group with more than three matches (H3 was found to have significantly lower post-transplant creatinine levels, compared to groups with three or fewer matches (H2 and H1, respectively. The median plasma levels of cytokines interleukin 6 (IL-6, tumor necrosis factor alpha (TNF-α, and interleukin 10 (IL-10 were evaluated according to the number of matches. Pro-inflammatory cytokines (IL-6 and TNF-α were significantly higher in groups with lower HLA compatibility. On the other hand, the regulatory cytokine IL-10 had significantly higher plasma levels in the group with greater compatibility between donor and recipient.Conclusion:These findings allow us to infer that pre-transplant HLA typing of donors and recipients can influence post-transplant renal graft function and may contribute to the development and choice of new treatment strategies.

    To develop a health management system for outpatient follow-up of kidney transplant patients. Access 2010 database software was used to establish the health management system for kidney transplantation patients in Windows XP operating system. Database management and post-operation follow-up of the kidney transplantation patients were realized through 6 function modules including data input, data query, data printing, questionnaire survey, data export, and follow-up management. The system worked stably and reliably, and the data input was easy and fast. The query, the counting and printing were convenient. Health management system for patients after kidney transplantation not only reduces the work pressure of the follow-up staff, but also improves the efficiency of outpatient follow-up.

    In iron overload diseases (thalassemia, sickle cell, and myelodysplastic syndrome), iron is deposited in all internal organs, leading to functional abnormalities. Hematopoietic stem cell transplantation (HSCT) is the only treatment offering a potential cure in these diseases. Our aim was to describe the experience in the field and the role of magnetic resonance imaging in the evaluation of iron overload before and after HSCT. Magnetic resonance imaging (MRI), using T2*, is the most commonly used tool to diagnose myocardial-liver iron overload and guide tailored treatment. Currently, HSCT offers complete cure in thalassemia major, after overcoming the immunologic barrier, and should be considered for all patients who have a suitable donor. The overall thalassemia-free survival of low-risk, HLA-matched sibling stem cell transplantation patients is 85-90%, with a 95% overall survival. The problems of rejection and engraftment are improving with the use of adequate immunosuppression. However, a detailed iron assessment of both heart and liver is necessary for pre- and post-transplant evaluation. In iron overload diseases, heart and liver iron evaluation is indispensable not only for the patients' survival, but also for evaluation before and after HSCT.

    We analyze the experience of the Center of General Surgery and Liver Transplantation from the Fundeni Clinical Institute (Bucharest, Romania) regarding orthotopic liver transplantation (OLT) in adult recipients, with whole liver grafts from cadaveric donors, between April 2000 (when the first successful LT was performed in Romania) and December 2004. This series includes 37 OLTs in adult recipients (16 women and 21 men, aged between 29-57 years--average 46 years). Other two LT with whole liver cadaveric grafts and two reduced-size LT were performed in children; also, in the same period, due to the acute organ shortage, other methods of LT were performed in 28 patients (21 living donor LT, 6 split LT and one "do mino" LT), that were not included in the present series. The indications for OLT were HBV cirrhosis--10, HBV+HDV cirrhosis--4, HCV cirrhosis--11, HBV+HCV cirrhosis--2, biliary cirrhosis--5, Wilson disease--2, alcoholic cirrhosis--1, non-alcoholic liver disease--1, autoimmune cirrhosis--1. With three exceptions, in which the classical transplantation technique was used, the liver was grafted following the technique described by Belghiti. Local postoperative complications occurred in 15 patients (41%) and general complications in 17 (46%); late complications were registered in 18 patients (49%) and recurrence of the initial disease in 6 patients (16%). Intrao- and postoperative mortality was 8% (3/37). There were two patients (5%) who died because of immunosuppressive drug neurotoxicity at more than 30 days following LT. Four patients (11%) died lately because of PTLD, liver venoocclusive disease, recurrent autoimmune hepatitis and liver venoocclusive disease, myocardial infarction, respectively. Thirty-four patients survived the postoperative period (92%); according to Kaplan-Meier analysis, actuarial patient-survival rate at month 31 was 75%.

    Full Text Available Melatonin (N-acetyl-5-methoxytryptamine is the main secretory product of the pineal gland in all mammals including humans, but it is also produced in other organs. It has been previously demonstrated to be a powerful organ-protective substance under oxidative stress conditions. The aim of this study was to evaluate the protective effect of melatonin in several organs such as heart, lung, kidney, and of the reproductive system, such as testis and epididymis in animals exposed to intermittent hypobaric hypoxia and therefore exposed to oxidative stress and analyzed by lipid peroxidation. Ten-week-old male Wistar rats were divided into 6 groups for 96 hours during 32 days under: 1 Normobaric conditions, 2 plus physiologic solution, 3 plus melatonin, 4 intermittent hypobaric hypoxia, 5 plus physiologic solution and 6 plus melatonin. The animals were injected with melatonin (10 mg/kg body weight at an interval of 96 hours during 32 days. Results indicated that melatonin decreased lipid peroxidation in heart, kidneys and lung under intermittent hypobaric hypoxia conditions. However, it did not exhibit any protective effect in liver, testis, epididymis and sperm count.

    Allogeneic stem cell transplant (alloSCT) can overcome the adverse prognosis of chronic lymphocytic leukemia with 17p deletion (17p- CLL). However, its applicability remains unclear. Since 2007, our leukemia service has referred patients with 17p- CLL for alloSCT at presentation. In this study, the outcomes of these patients were reviewed retrospectively to determine whether they underwent alloSCT and why patients did not undergo alloSCT. Fifty-two patients with 17p- CLL who were referred to the transplant service from 2007 to 2010 were identified. Of these patients, 32 (62%) did not undergo alloSCT, mainly because of treatment- or disease-related complications (n = 15). The 2-year post-referral overall survival rates of the alloSCT and non-SCT groups were 64% and 25%, respectively (p = 0.001). These findings suggest that while alloSCT is an effective therapy in patients with 17p- CLL, pre-SCT complications may preclude a significant proportion of patients from undergoing the procedure.

    Full Text Available Context There is a relative lack of studies about exhaled nitrite (NO2- concentrations in cirrhotic and transplanted patients. Objective Verify possible differences and correlations between the levels of NO2-, measured in plasma and exhaled breath condensate collected from patients with cirrhosis and liver transplant. Method Sixty adult male patients, aged between 27 and 67 years, were subdivided into three groups: a control group comprised of 15 healthy volunteers, a cirrhosis group composed of 15 volunteers, and a transplant group comprised of 30 volunteers. The NO2- concentrations were measured by chemiluminescence. Results 1 The analysis of plasma NO2- held among the three groups showed no statistical significance. 2 The comparison between cirrhotic and control groups, control and transplanted and cirrhotic and transplanted was not statistically significant. 3 The measurements performed on of NO2- exhaled breath condensate among the three groups showed no statistical difference. 4 When comparing the control group samples and cirrhotic, control and transplanted and cirrhotic and transplanted, there was no significant changes in the concentrations of NO2-. Conclusion No correlations were found between plasma and exhaled NO2-, suggesting that the exhaled NO2- is more reflective of local respiratory NO release than the systemic circulation.

    There is currently no unified view regarding whether liver transplantation or splenectomy should be performed for hypersplenism before liver transplantation in biliary atresia (BA) patients. We herein describe the efficacy of splenectomy before liver transplantation. Splenectomy was performed in ten patients with hypersplenism associated with BA. We retrospectively reviewed their perioperative and postoperative courses, the number of leukocytes and thrombocytes, and the MELD score. The mean age was 17.5±7.0years (range 11-31years), and the male-to-female ratio was 1:1. The platelet and leukocyte levels increased after splenectomy and returned to normal levels one month postoperatively. The mean MELD score after splenectomy was significantly decreased after splenectomy: 10±2.1 vs 7.6±1.8. In particular, PT-INR improved. Five patients underwent liver transplantation because of hepatopulmonary syndrome and repeated bouts of cholangitis, whereas the remaining five patients did not undergo liver transplantation because of improvements in the liver function (the mean follow-up period was 56months). The postoperative complications included portal vein thrombosis and intestinal perforation, but the patient survival rates remained at 100%. After splenectomy, both pancytopenia and the liver function clearly improved. Splenectomy should therefore be a treatment option for patients with hypersplenism before liver transplantation.

    Performing a pretransplantation splenectomy in patients with myelofibrosis (MF) is a matter of debate, as while the procedure improves hematological recovery, it may lead to severe morbidities. We retrospectively analyzed data from 85 consecutive patients who underwent transplantation in our center for MF, including 39 patients who underwent splenectomy before their transplantation. A majority of them had primary MF (78%), were considered high-risk patients (84% dynamic international prognostic scoring system intermediate-2 or higher), and had received transplants from HLA-matched sibling donors (56%) after a reduced-intensity conditioning regimen (82%). One-half of all splenectomized patients presented surgical or postsurgical morbidities, most frequently thrombosis and hemorrhage. After adjustment using Cox models, pretransplantation splenectomy was not associated with nonrelapse mortality or post-transplantation relapse but with an improved overall survival (OS) and event-free survival (EFS). We conclude that some patients with huge splenomegaly may undergo pretransplantation splenectomy without a deleterious impact on post-transplantation outcomes. OS and EFS improvement should in confirmed in controlled study. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.

    Solid organ and stem cell transplant patients and their caregivers report a substantial level of distress. Mindfulness-based stress reduction has been shown to alleviate distress associated with transplant, but there is limited experience in this population with other mindfulness-based interventions, or with combined transplant patient and caregiver interventions. We evaluated a novel, 6-week mindfulness-based resilience training (MBRT) class for transplant patients and their caregivers that incorporates mindfulness practice, yoga, and neuroscience of stress and resilience. Thirty-one heart, liver, kidney/pancreas, and stem cell transplant patients and 18 caregivers at Mayo Clinic in Arizona participated. Measures of stress, resilience, depression, anxiety, health-related quality of life, positive and negative affect, and sleep were completed at baseline, 6 weeks, and 3 months postintervention. At 6 weeks and 3 months, patients demonstrated significant (Presilience and manage stress for transplant patients and their caregivers. © 2016 John Wiley & Sons A/S.

    The aim of this study is to investigate the relationship between the epidemiological and clinical profiles of patients before and after hematopoietic stem cell transplantation (HSCT) and the need for endodontic treatment. The subjects included 188 individuals enrolled in the dental care program for transplanted patients of the School of Dentistry, Federal University of Minas Gerais (Faculdade de Odontologia da Universidade Federal de Minas Gerais, FO-UFMG) from March 2011 through March 2016. The patients were subjected to an HSCT conditioning dental regimen based on a thorough clinical and radiographic evaluation. Intraoral periapical and bite-wing X-rays were obtained, and after evaluation, specific dental treatment was planned and performed. The following demographic and clinical data were collected from the patients' medical records: age, gender, transplantation stage, primary disease, transplant type, medication used, complete blood count at the time of visit, and need for endodontic treatment. The Kolmogorov-Smirnov and the chi-square tests were used. Leukemia (31.3%) and multiple myeloma (17.9%) were the most prevalent primary diseases. Most patients were subjected to allogeneic-related transplantation (83.6%). Most patients exhibited platelet counts and hemoglobin concentrations below the reference values in the pre-transplantation stage, while the neutrophil and platelet counts and the hemoglobin levels were within the reference ranges in the post-transplantation stage. The proportions of individuals requiring endodontic treatment were similar between the pre- and post-transplantation groups: 24.3% and 24.7%, respectively. The systemic conditions of the patients referred for dental treatment were compromised.

    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts

    Relapse of chronic myelogenous leukemia after bone marrow transplantation can be detected by using clinical, cytogenetic, or molecular tools. A modification of the polymerase chain reaction can be used in patients to detect low levels of the BCR-ABL-encoded mRNA transcript, a specific marker for chronic myelogenous leukemia. Early detection of relapse after bone marrow transplantation could potentially alter treatment decisions. The authors prospectively evaluated 19 patients for evidence of molecular relapse, cytogenetic relapse, and clinical relapse after bone marrow transplantation. They used the polymerase chain reaction to detect residual BCR-ABL mRNA in patients followed up to 45 months after treatment and found 4 patients with BCR-ABL mRNA expression following bone marrow transplantation. Fifteen patients did not express detectable BCR-ABL mRNA. All 19 patients remain in clinical remission. In this prospective study of chronic myelogenous leukemia patients treated with bone marrow transplantation, molecular relapse preceded cytogenetic relapse in those patients who persistently express BCR-ABL mRNA. They recommend using standard clinical and cytogenetic testing to make patient care decisions until further follow-up determines the clinical outcome of those patients with residual BCR-ABL mRNA transcripts detected by polymerase chain reaction

    Full Text Available The objective of the study is to evaluate the relationship between serum testos-terone levels and cardiovascular risk factors (CVRF in patients after kidney transplantation and with chronic kidney disease (CKD. Seventy-five male patients, aged between 18 and 68 years, who had kidney transplantation at least six months earlier, were enrolled into the study. Only renal transplant recipients and CKD patients with a creatinine level of 0.05. Serum testosterone levels were independent risk factors affecting IVC collapse index, systolic BP and LA. m-TORi and CNIs drugs might have no negative effect on serum testosterone levels, and improvement of the serum testosterone levels after transplantation might have a positive contribution on cardiac risk factors.

    The Eurotransplant High-Urgency (HU) Heart Transplantation Program allows urgent heart transplants to be carried out in rapidly deteriorating patients with acute-to-chronic heart failure on the elective waiting list. But do the results of HU heart transplantation justify performing primary heart transplantation in these critically ill patients and offer an acceptable outcome? Between 2000 and 2004, 64 heart transplantations (HTx) (32 elective and 32 HU-HTx) were performed in our department. After having been accepted in an auditing process based on HU criteria, intensive care patients in NYHA functional class IV (cardiac index 1.7 l/min/qm BS), in end-organ failure (creatinine 1.5 mg/dl), and with catecholamine dependence (dobutamine 8 microg/kg/min), are given priority with respect to organ allocation, and their data were compared to data from elective patients from the same period. HU requests were accepted in 97 % of cases. Two requests were not accepted, and both patients with contraindications for assist device implantation died within one week. The HU patients were 100 % in NYHA class IV, 93 % of the elective patients were in NYHA class III. Waiting time on the HU list was 13 days, and 7 of these patients died before HTx. Following heart transplantation, survival rates at 30 days and at one year of the HU group were 88 % and 85 % versus 94 % and 93 % in the elective group. This study shows that end-stage heart failure patients in the HU program can be transplanted primarily with good results if an organ is available in time. We are still in the position where the HU program only manages the organ shortage; there are still too many patients on the waiting list who die before receiving a donor organ.

    Full Text Available Urinary neutrophil gelatinase-associated lipocalin (uNGAL is known to predict the prolonged delayed graft function after kidney transplantation. We examined the relation of uNGAL with histological findings of acute tubular injury (ATI. Analyses were made in biopsies taken at 6 weeks, 3 months, and 6 months after kidney transplantation. uNGAL was measured in the spot urines, normalized to urinary creatinine excretion, and correlated to biopsy findings and clinical, laboratory, and demographic variables. Controls included healthy individuals, individuals after kidney donation and ICU patients with acute kidney failure. Renal transplant recipients without ATI did not display elevated uNGAL levels compared to the healthy controls. Transplant patients with ATI had a higher uNGAL excretion at 6 weeks than patients without ATI (27,435 versus 13,605 ng/g; P=0.031. This increase in uNGAL was minor compared to ICU patients with acute renal failure (2.05×106 ng/g. Patients with repeated findings of ATI or severe ATI did not have higher urinary NGAL levels compared to those with only one ATI finding or moderate ATI. Female recipient gender and urinary tract infection were identified as potential confounders. uNGAL has a relation with histological signs of acute tubular injury. The usability of this biomarker in renal allograft recipients is limited because of the low sensitivity.

    Morphological criteria have always been considered the benchmark for selecting hepatocellular carcinoma (HCC) patients for liver transplantation (LT). These criteria, which are often inappropriate to express the tumor’s biological behavior and aggressiveness, offer only a static view of the disease burden and are frequently unable to correctly stratify the tumor recurrence risk after LT. Alpha-fetoprotein (AFP) and its progression as well as AFP-mRNA, AFP-L3%, des-γ-carboxyprothrombin, inflammatory markers and other serological tests appear to be correlated with post-transplant outcomes. Several other markers for patient selection including functional imaging studies such as 18F-FDG-PET imaging, histological evaluation of tumor grade, tissue-specific biomarkers, and molecular signatures have been outlined in the literature. HCC growth rate and response to pre-transplant therapies can further contribute to the transplant evaluation process of HCC patients. While AFP, its progression, and HCC response to pre-transplant therapy have already been used as a part of an integrated prognostic model for selecting patients, the utility of other markers in the transplant setting is still under investigation. This article intends to review the data in the literature concerning predictors that could be included in an integrated LT selection model and to evaluate the importance of biological aggressiveness in the evaluation process of these patients.

    Background: Stem cell transplantation is an emerging method of treatment for patients with cardiovascular disease. There are few studies completed or ongoing on stem cell therapy in patients with idiopathic dilated cardiomyopathy (IDCM). Information on stem cell homing and distribution in the myocardium after transplantation might provide important insight into effectiveness of transplantation procedure. Aim: To assess early engraftment, retention and migration of intracoronarily transplanted stem cells in the myocardium of patients with advanced dilated cardiomyopathy of non-ischaemic origin using stem cell labeling with 99m Tc-exametazime (HMPAO). Materials, methods: Thirty-five patients with IDCM and advanced heart failure were included in the study. Autologous hematopoietic (CD34 +) stem cells were harvested by peripheral blood apheresis after bone marrow stimulation, labeled with 99m Tc-HMPAO, tested for viability and injected into coronary vessel supplying areas of myocardium selected by myocardial perfusion scintigraphy as dysfunctional yet viable. Imaging was performed 1 h and 18 h after transplantation. Results: Myocardial stem cell retention ranged from 0 to 1.44% on early and 0–0.97% on delayed imaging. Significant efflux of stem cells occurred from site of delivery in this time period (p < 0.001). Stem cell viability was not affected by labeling. Conclusion: Stem cell labeling with 99m Tc-HMPAO is a feasible method for stem cell tracking after transplantation in patients with IDCM.

    Organ procurement in China has been criticized because of its reliance on executed prisoners as donors. We aimed to assess the influence of perceptions about organ procurement practices in China on domestic patient-care decisions. An anonymous internet administered case-based questionnaire was used to survey a sample of healthcare professionals with affiliations to hepatology and transplantation professional societies. Of 674 completed surveys, the vast majority (93%) of the respondents were physicians, surgeons or allied transplant professionals actively caring for liver transplant patients and 81% practiced in the US. A strong majority believed procurement practices were ethically sound in the US and Europe (87% and 73%) but fare fewer believed that procurement practices were ethically sound in China (4%, p < 0.001). In case-based questions, lack of confidence in the ethical standards of organ procurement in China predicted patient-care decisions. The majority would provide post-transplantation care for patients who underwent liver transplantation at another domestic center, in a foreign country and in China (90%, 78%, and 63%, respectively, p < 0.001) yet respondents who suspected unethical procurement practices in China were more reluctant to do so (p < 0.001). Transplant professionals expressed concern about organ procurement practices in China which influenced their patient-care decision-making.

    In 2005 the Italian National Transplant Centre (CNT) signed a cooperation agreement with the Hellenic Transplant Organization (HTO) fostering the transfer and transplantation of urgent Greek liver patients at Italian transplantation centers. So as to not reduce access to transplantation for Italian patients, the agreement provided compensation for organs allocated to Greek transplant recipients. The aim of this study was to analyze the flow of patients from Greece to Italy and the number of received livers to consider the possibility to extend this kind of agreement to other countries, so that this should not penalize Italian recipients. The agreement provides the possibility for Greek patients affected by acute disease to be transferred to Italian transplantation centers participating in the agreement. Until 2008 livers transplanted into Greek recipients were returned through a preferential offer of surplus Greek organs, whereas from 2009 an obligation of payback was introduced. During the reviewed period requests for transfer, transferred patients, and number of patients who later underwent transplantation in Italy were 56, 26, and 23, respectively. Livers offered by the Greek organization that were accepted, transferred, and transplanted in Italy have been 82, 50, and 44, respectively. According to our analysis, the cooperation has had as positive impact for both Greece, which has difficulties transplanting urgent recipient because of the low number of donors, and for Italy, which is not penalized by the use of an organ in a Greek recipients, but is also rewarded for helpfulness.

    Full Text Available Heart Transplantation (HTx to date remains the most effective and radical method of treatment of patients with end-stage heart failure. The defi cit of donor hearts is forcing to resort increasingly to the use of different longterm mechanical circulatory support systems, including as a «bridge» to the follow-up HTx. According to the ISHLT Registry the number of recipients underwent cardiopulmonary bypass surgery increased from 40% in the period from 2004 to 2008 to 49.6% for the period from 2009 to 2015. HTx performed in repeated patients, on the one hand, involves considerable technical diffi culties and high risks; on the other hand, there is often no alternative medical intervention to HTx, and if not dictated by absolute contradictions the denial of the surgery is equivalent to 100% mortality. This review summarizes the results of a number of published studies aimed at understanding the immediate and late results of HTx in patients, previously underwent open heart surgery. The effect of resternotomy during HTx and that of the specifi c features associated with its implementation in recipients previously operated on open heart, and its effects on the immediate and long-term survival were considered in this review. Results of studies analyzing the risk factors for perioperative complications in repeated recipients were also demonstrated. Separately, HTx risks after implantation of prolonged mechanical circulatory support systems were examined. The literature does not allow to clearly defi ning the impact factor of earlier performed open heart surgery on the course of perioperative period and on the prognosis of survival in recipients who underwent HTx. On the other hand, subject to the regular fl ow of HTx and the perioperative period the risks in this clinical situation are justifi ed as a long-term prognosis of recipients previously conducted open heart surgery and are comparable to those of patients who underwent primary HTx.

    The number of end-stage renal disease (ESRD) patients with preformed antibodies waiting for a kidney transplant has been increasing lately. We conducted a nationwide study on the outcomes of kidney transplantation after desensitization in Korea. Six transplant centers have run desensitization programs. The patients who underwent living donor kidney transplantation after desensitization from 2002 to 2010 were retrospectively analyzed. A total of 86 cases were enrolled. Thirty-five of these were cases of re-transplantation (40.7 %). Indications of desensitization were positive complement-dependent cytotoxicity (CDC) cross-match responses (CDC(+), 36.0 %), positive flow-cytometric cross-match responses (FCX(+), 54.7 %), and positive donor-specific antibodies (DSA(+), 8.1 %). The desensitization protocols used pre-transplant plasmapheresis (95.3 %), intravenous immunoglobulin (62.8 %), and rituximab (67.4 %). Acute rejection occurred in 18 patients (20.9 %), graft failure occurred in 4 patients, and the 3-year graft survival rate was 93.8 %. The presence of DSA increased the acute rejection rate (P = 0.015) and decreased the 1-year post-transplant estimated glomerular filtration rate (P = 0.006). Although rejection-free survival rates did not differ significantly between the CDC(+) and FCX(+) groups, the 1-year estimated glomerular filtration rate was lower in the CDC(+) group (P = 0.010). Infectious and significant bleeding complications occurred in 15.5 % and 4.7 % of cases, respectively. Kidney transplantation after desensitization had good graft outcomes and tolerable complications in Korea, and therefore, this therapy can be recommended for sensitized ESRD patients.

    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.

    Avascular necrosis of bone (AVN) may cripple a patient who has had a successful renal transplant. The authors have attempted to gain more knowledge of this condition by undertaking a prospective survey to determine as accurately as possible the incidence of AVN in renal transplant patients. Routine six-month whole body bone scans were performed with /sup 99m/Technetium Methylene Diphosphonate in 42 consecutive surviving renal transplant patients. The survey started in 1978-79, and patients were followed for a minimum of two years and a maximum of three years. As a result, seven were found to have AVN that would have remained undetected in two of the patients if routine whole body bone scanning had not been conducted. Despite a reduction in steroid dosage in recent years, the incidence of AVN in the authors patients remains high at 17%. Bone scan appearances in renal transplant patients were classified and subdivided into four groups. By linking bone scans and radiographic and postmortem appearances of the femoral head, one very early case of AVN was detected. Routine bone scanning provided a more accurate estimation of the incidence of fractures in renal transplant patients

    It has been reported in literature that self-esteem increases in patients who pass from continuous ambulatory peritoneal dialysis to renal transplantation. However, our clinical observations in the Department of Nephrology of Hospital Infantil de México Federico Gómez indicate otherwise. Therefore, we carried out this research on 60 patients, children and adolescents, male and female between the ages from 8 to 15 years old, and we applied them the Coopersmith self-esteem questionnaire, which has been validated in mexican population. These findings indicate that the social environment continuous ambulatory peritoneal dialysis patients feel more adapted than patients in renal transplant (p = 0.05). However it was also observed that these patients tried to show a better image on their situation through compensatory mechanisms (defense p = 0.03). It was concluded that it would be necessary to follow the adaptation of the transplanted patients, in order to help them achieve complete rehabilitation.

    This study is to develop a therapeutic drug monitoring (TDM) network server of tacrolimus for Chinese renal transplant patients, which can facilitate doctor to manage patients' information and provide three levels of predictions. Database management system MySQL was employed to build and manage the database of patients and doctors' information, and hypertext mark-up language (HTML) and Java server pages (JSP) technology were employed to construct network server for database management. Based on the population pharmacokinetic model of tacrolimus for Chinese renal transplant patients, above program languages were used to construct the population prediction and subpopulation prediction modules. Based on Bayesian principle and maximization of the posterior probability function, an objective function was established, and minimized by an optimization algorithm to estimate patient's individual pharmacokinetic parameters. It is proved that the network server has the basic functions for database management and three levels of prediction to aid doctor to optimize the regimen of tacrolimus for Chinese renal transplant patients.

     Dispositional optimism is a personal resource that determines the coping style and adaptive response to chronic diseases. The aim of this study was to assess the correlations between dispositional optimism and coping strategies in patients with recent kidney transplantation and evaluate the differences in the use of coping strategies in accordance with the level of dispositional optimism.  Patients who were hospitalised in the nephrology department were selected consecutively after kidney transplantation was performed. The evaluation instruments were the Life Orientation Test-Revised, and the Coping Strategies Inventory. The data were analysed with central tendency measures, correlation analyses and means were compared using Student’s t-test.   66 patients with a kidney transplant participated in the study. The coping styles that characterised patients with a recent kidney transplantation were Social withdrawal and Problem avoidance. Correlations between dispositional optimism and coping strategies were significant in a positive direction in Problem-solving (p<.05) and Cognitive restructuring (p<.01), and inversely with Self-criticism (p<.05). Differences in dispositional optimism created significant differences in the Self-Criticism dimension (t=2.58; p<.01).  Dispositional optimism scores provide differences in coping responses after kidney transplantation. Moreover, coping strategies may influence the patient’s perception of emotional wellbeing after kidney transplantation.

Using previously reported labeling methods, 63 studies with this agent have been performed in 53 renal transplant patients. Indications for study included suspected rejection or cytomegalovirus (CMV) infection. Studies were performed in 33 men and 20 women, with ages ranging from 6 to 68 years. Autologous cells were normally used for labeling, although leukocytes obtained from ABO-compatible donors were used in three subjects. Rectilinear scanner and/or scintillation camera images were obtained at 24 hours after intravenous administration of 0.1 to 0.6 mCi of In-111-leukocytes. There was abnormal uptake of In-111-leukocytes in the transplanted kidney in 11 of 15 cases of rejection. In three additional cases of increased transplant uptake, CMV infection was present in two. Abnormal lung uptake was present in 13 of 14 patients with CMV infection. In four additional cases, increased lung uptake was associated with other pulmonary inflammatory disease. Increased lung activity was not seen in patients with uncomplicated transplant rejection. These results suggest that In-111-leukocyte imaging may be useful in the differential diagnosis of rejection versus CMV infection in renal transplant patients

    Highly immunized patients are a challenge for organ transplantation programs. One way of increasing the likelihood of transplantation in this group of patients is to expand the possible donations by defining acceptable HLA mismatches. In the Scandiatransplant Acceptable Mismatch Program (STAMP), a de-centralized approach has been implemented in 2009. The program has been improved during the years from utilizing HLA-A, -B, -DR matching only to include typing of all deceased donors for HLA-A, -B, -C, -DRB1 and -DQB1. The calculation of a transplantability score (TS) has been introduced in order to take both HLA and AB0 into consideration resulting in a more realistic picture of the transplantability chance. Patients were selected for eligibility and results of immunisation status were prepared in each of the 9 tissue typing laboratories, while access to the program is finally governed by a common steering group of immunologists and clinicians. In the period from March 2009 until February 2015, 96 patients were transplanted within this program. The mean recipient age was 49 years and 57% were females, 30% of the patients were first transplants and of these 93% were females. The majority of the patients had 2-5 HLA-A, -B. -DR mismatches. The allograft survival at 60 months was 79.1%. Applying the TS to the cohort confirmed that patients with a low TS score had longer waiting times. The program has matured during the years and now proves to be a valid approach for transplanting highly immunized patients. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Extracorporeal membrane oxygenation (ECMO), when used as bridge to lung transplantation, (BTT) identifies high-risk candidates. Recent advances in cannula design and patient selection fosters "awake ambulatory ECMO" as a viable option for critically ill candidates in an attempt to retard deconditioning while awaiting allografts. From 2012 to 2015, 30 patients underwent ECMO as BTT. Candidacy for ECMO was determined before listing for transplant. A dual-lumen single cannula was used first in 13 of 30 patients (43%). Of the remaining 30 patients, 6 (20%) were supported with venoarterial ECMO and 11 (37%) with venovenous ECMO, with double-site cannulation in 11 (37%), and 6 of 11 converted to a dual-lumen single cannula. All ECMO patients were managed in a dedicated heart/lung failure intensive care unit, and early aggressive physical therapy, ambulation, and spontaneous breathing trials were emphasized. BTT was successful in 26 patients (87%). In the 19 patients with dual-lumen single cannula, 5 (26%) were successfully ambulated, and 6 (32%) achieved spontaneous ventilation. Median (25th, 75th percentile) lengths of stay in the intensive care unit and hospital were 33 days (20, 46 days) and 56 days (28, 78 days), respectively, and were 20 and 31 days, respectively, in patients successfully ambulated (intensive care unit: p = 0.5; hospital: p = 0.4). Among all patients who received a transplant, 30-day, 1-year, and 3-year survival were 92%, 85%, and 80%, respectively. Among patients undergoing primary transplants, 3-year survival was 91%. ECMO as BTT has led to encouraging perioperative outcomes and early survival. Careful patient selection and early use of ECMO seems to allow for preservation of vitality while these critically ill candidates await donor organs, which may improve outcomes.

    Although outpatient autologous stem cell transplantation (ASCT) is safe and feasible in most instances, some patients undergoing planned outpatient transplantation for multiple myeloma (MM) will need inpatient admission for transplantation-related complications. We aim to evaluate the difference, if any, between outpatient and inpatient ASCT cohorts of MM patients in terms of admission rate, transplantation outcome, and overall survival. We also plan to assess whether the Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) and Karnofsky Performance Status (KPS) can predict unplanned admissions after adjusting for confounding factors. Patients with MM (n = 448) who underwent transplantation at our institution between 2009 and 2014 were included in this retrospective analysis. Patients were grouped into 3 cohorts: cohort A, planned inpatient ASCT (n = 216); cohort B, unplanned inpatient admissions (n = 57); and cohort C, planned outpatient SCT (n = 175). The statistical approach included descriptive, bivariate, and survival analyses. There were no differences among the 3 cohorts in terms of type of myeloma, stage at diagnosis, time from diagnosis to transplantation, CD34 cell dose, engraftment kinetics, and 100-day response rates. Serum creatinine was higher and patients were relatively older in both the planned inpatient (median age, 62 years; range, 33 to 80 years) and unplanned (median age, 59 years; range, 44 to 69 years) admission cohorts compared with the outpatient-only cohort (median age, 57 years; range, 40 to 70 years) (P Performance status (cohort A: median, 90%; range, 60% to 100%; cohort B: 80%, 50% to 100%; cohort C: 80%, 60% to 100%) was lower (P performance status (KPS 2 also appeared to be associated with worse outcomes compared with HCT-CI 0 to 1, the the difference did not reach statistical significance (hazard ratio, 1.41l 95% confidence interval, 0.72 to 2.76).

Baseline information and also data related to fever and neutropenia, patient's outcomes, duration of hospitalization and antibiotic use pattern were documented.A total of 195 patients were analyzed and a total of 268 febrile episodes in 180 patients were recorded (mean 1.5 episodes per patient. About 222 episodes (82% were associated with neutropenia which one-fourth of them were without any documented infection sources. Microbiologic documents showed that the relative frequencies of gram positive and gram negative bacteria were 62.5% and 37.5%, respectively. The hospital stay duration was directly related to the numbers of fever episodes (P<0.0001.The rate of febrile episodes in autologous stem cell transplantation was significantly higher compared to allogeneic type (P<0.05.It is necessary to determine not only the local profile of microbiologic pattern, but also antibiotic sensitivities in febrile neutropenic patients following hematopoietic stem cell transplantation, and reassess response to antibiotic treatment to establish any necessity for modifications to treatment guidelines in order to prevent any fatal complications from infection.

    Full Text Available Background. This study was designed to evaluate the impact of various prognostic factors on long-term survival and event free survival after allogeneic hematopoietic stem cell transplantation for patients with acute leukemia.Methods and patients. Between years 1989 and 2002 44 patients with acute leukemia (30 with AML and 14 with ALL were transplanted. Survival curves using the Kaplan-Meier method were calculated for patients transplanted with two different sources of stem cells – bone marrow and peripheral blood and separately for patients with female donor.Results. Estimated 10 years survival for AML is 43% and 64% for ALL patients which is not statistically different. There are no significant differences in outcome regarding source of stem cells and in donors’ gender.Conclusions. To conclude, our results show that neither source of stem cells nor donor’s gender has impact on the long-term survival after hematopoietic stem cell transplantation. As published previously patients transplanted beyond the first remission have significantly worse outcome.

    Lung transplantation is commonly used for patients with end-stage lung disease. However, there is continuing debate on the optimal operation for patients with chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. Single-lung transplantation (SLT) provides equivalent short- and medium-term results compared with bilateral lung transplantation (BLT), but long-term survival appears slightly better in BLT recipients (especially in patients with COPD). The number of available organs for lung transplantation also influences the choice of operation. Recent developments suggest that the organ donor shortage is not as severe as previously thought, making BLT a possible alternative for more patients. Among the different complications, re-implantation edema, infection, rejection, and bronchial complications predominate. Chronic rejection, also called obliterative bronchiolitis syndrome, is a later complication which can be observed in about half of the patients. Improvement in graft survival depends greatly in improvement in prevention and management of complications. Despite such complications, graft survival in fibrosis patients is greater than spontaneous survival on the waiting list; idiopathic fibrosis is associated with the highest mortality on the waiting list. Patients should be referred early for the pre-transplantation work-up because individual prognosis is very difficult to predict.

    Full Text Available Introduction: Autologous haemopoietic stem cell transplantation (SCT is an important treatment modality for patients with acute myeloid leukemia with low and intermediate risk disease. It has served advantages over allogenic transplantation, because it does not need a matched donor, there is no graft versus host disease, there are less complications and a faster immune reconstitution than in the allo-setting. The disadvantage is the lack of the graft versus leukaemia effect.

    Transplant tourism (TT) is the term used to describe travel outside one's country of abode for the sole purpose of obtaining organ transplantation services. This study describes the characteristics and outcomes of kidney transplant tourists who were followed up in our institution. A retrospective study was conducted on patients who underwent kidney transplantation outside the country and were followed up in our institution from 2007 to 2015. 26 patients were followed up; 19 (73%) were males. The mean±SD age of patients was 40.5±10.3 years. The majority (n=20) of the transplantations were carried out in India. Living-unrelated transplants were most common (54%). Complications encountered were infections in 11 (42%) patients, new-onset diabetes after transplantation in 9 (35%), chronic allograft nephropathy in 8 (31%), biopsy-proven acute rejections in 3 (12%), and primary non-function in 2 (8%). 1-year graft survival was 81% and 1-year patient survival was 85%. Kidney transplant tourism is still common among Nigerian patients with end-stage renal disease. Short-term graft and patient survival rates were poorer than values recommended for living kidney transplants. We therefore advise that TT should be discouraged in Nigeria, given the availability of transplantation services in the country, and also in line with international efforts to curb the practice.

    Chronic administration of immunosuppressants has been associated with long-term consequences, including a higher risk of neoplasm development. The processes regulating telomere function exert a major influence on human cancer biology. The present study aimed to assess the effect of immunosuppressive therapy on the expression of genes associated with telomere maintenance and protection in patients following renal transplantation. A total of 51 patients that had undergone kidney transplantation and 54 healthy controls were enrolled in the study. The 51 transplant patients received a three-drug immunosuppressive regimen consisting of cyclosporine A, prednisone and mycophenolate mofetil. In stage 1 of the study, the expression profiles of 123 transcripts, which represented 70 genes, were assessed in peripheral mononuclear blood cells using an oligonucleotide microarray technique in 8 transplant recipients and 4 healthy control subjects. Among the analyzed transcripts, the expression levels of 4 differed significantly between the studied groups; however, only the ACD (adrenocortical dysplasia homolog) gene, encoding the telomere-binding protein POT1-interacting protein 1 (TPP1), was sufficiently specific for telomere homeostasis. The expression of ACD was downregulated in transplant recipients (fold change, 2.11; P=0.006). In stage 2 of the study, reverse transcription-quantitative polymerase chain reaction analysis of ACD , DKC1 and hTERT mRNA was conducted for all transplant patients and control subjects. The results confirmed the downregulation of the ACD gene in patients that had received immunosuppressive therapy (P=0.002). The results of the present study indicate that the downregulation of ACD gene transcription, and thus TPP1 protein expression, may enhance the capacity for cell immortalization, despite normal levels of other key telomere maintenance factors, in patients undergoing immunosuppressive therapy. Furthermore, the results indicate that TPP1 has

    Fecal microbiota transplantation (FMT) is increasingly being performed for Clostridium difficile infection in solid organ transplant (SOT) patients; however, little is known about the potential pharmacokinetic or pharmacomicrobial effects this may have on tacrolimus levels. We reviewed the medical records of 10 SOT patients from September 2012-December 2016 who were taking tacrolimus at time of FMT for recurrent C. difficile infection. We compared the differences in tacrolimus concentration/dose ratio (C/D ratio) 3 months prior to FMT vs 3 months after FMT. The mean of the differences in C/D ratio calculated as (ng/mL)/(mg/kg/d) was -17.65 (95% CI -1.25 to 0.58) (ng/mL)/(mg/kg/d), P-value .43 by Wilcoxon signed-rank test. The mean of the differences in C/D ratio calculated as (ng/mL)/(mg/d) was -0.33 (95% CI -1.25 to 0.58) (ng/mL)/(mg/d), P-value .28 by Wilcoxon signed-rank test. Of these patients, 2/10 underwent allograft biopsy for allograft dysfunction in the year after FMT, with no evidence of allograft rejection on pathology. These preliminary data suggest that FMT may not predictably alter tacrolimus levels and support its safety for SOT patients however further study in randomized trials is needed. © 2018 John Wiley & Sons A/S.

    Socio-economic rehabilitation is an important outcome parameter in successful renal transplant recipients, particularly in developing countries with low income patients who often depend on extraneous sources to fund their surgery costs. We studied the socioeconomic rehabilitation and changes in socioeconomic status (SES) of successful renal allograft recipients among Indian patients and its correlation with their source of funding for the surgery. A cross-sectional, questionnaire-based study was conducted on 183 patients between January 2010 to January 2013. Patients with follow up of at least 1 year after successful renal transplant were included. During interview, two questionnaires were administered, one related to the SES including source of funding before transplantation and another one relating to the same at time of interview. Changes in SES were categorized as improvement, stable and deterioration if post-transplant SES score increased >5%, increased or decreased by 5% of pre-transplant value, respectively. In this cohort, 97 (52.7%), 67 (36.4%) and 19 (10.3%) patients were non-funded (self-funded), one-time funded and continuous funded, respectively. Fifty-six (30.4%) recipients had improvement in SES, whereas 89 (48.4%) and 38 (20.7%) recipients had deterioration and stable SES. Improvement in SES was seen in 68% patients with continuous funding support whereas, in only 36% and 12% patients with non-funded and onetime funding support (P = 0.001) respectively. Significant correlation was found (R = 0.715) between baseline socioeconomic strata and changes in SES after transplant. 70% of the patients with upper and upper middle class status had improving SES. Patients with middle class, lower middle and lower class had deterioration of SES after transplant in 47.4%, 79.6% and 66.7% patients, respectively. Most of the recipients from middle and lower social strata, which included more than 65% of our patient's population, had deteriorating SES even after a

    Objective: To discuss the perioperative nursing care of patients who is going to receive interventional therapy for hepatic artery stenosis after liver transplantation and to provide useful reference for reducing surgery-related complication and for improving the prognosis of patients. Methods: Based on the patient's condition and operative requirement,we provided effective nursing care for 20 patients who were admitted to receive the interventional therapy for hepatic artery stenosis after liver transplantation. The nursing care included preoperative preparation,postoperative nursing and medical guidance at the time of discharge. Results: Interventional therapy was successfully performed in all 20 cases, and no hemorrhagic tendency or acute thrombosis occurred. Marked symptomatic improvement was obtained in all patients. Conclusion: The interventional therapy is an effective treatment for hepatic artery stenosis after liver transplantation. Intensive perioperative nursing care can well prevent the occurrence of surgery-related complications and can surely improve the therapeutic results. (authors)

RESULTS The mean age of the study population was 43.98 years old, 50% of these individuals were between 5-10 years of transplantation and 50% between 10-15 years. Changes in mobility and balance (TUG were found in 9.3% of transplant patients, while 2.3% had deficits in functional independence (FIM. The association between TUG and the FIM (χ2= 19.964, p< 0.001 was found in 25% of the 9.3% of individuals who showed changes in TUG. It was found that only 20.9% of kidney transplant between 5-10 years and 14.0% between 11 and 15 years performed regular physical exercises (χ2= 0.727, p= 0.394 and 67.4% presented prevalent complaints on lower limbs musculoskeletal. CONCLUSION Although the level of dependence and impairments in mobility and balance found in renal transplants are low, deficits in mobility and balance may lead to changes in the ability to perform their functional activities independently.

    To explore and compare complementary and alternative medicine (CAM) practice among subsets of patients with chronic kidney disease (CKD) and renal allograft recipients. Cross-sectional survey questionnaire. Three outpatient nephrology clinics and dialysis centers in Egypt.

    Translational research is an evolving discipline that is intended to bridge the gaps between basic science research, clinical research, and implementation in clinical practice. It is a fluid, multidirectional process that requires strong interdisciplinary collaboration to produce research that is relevant to end-users. This review summarizes current perspectives on translational research and outlines its relevance and importance to kidney transplantation research. Sources of information used for this review include published reports, articles, and research funding websites. Tissue typing is used as an in-depth example of how translational research has been applied in the field of kidney transplant medicine, and how it has resulted in successful implementation of diagnostic and management options for sensitized individuals undergoing kidney transplantation. The value of actively involving kidney transplant stakeholders (patients, caregivers, and clinicians) in setting research priorities and determining relevant outcomes for future investigation is also discussed. This is a narrative review of the literature which has been partly influenced by the perspectives and experiences of its authors. Translational and patient-oriented research practices should be incorporated into future research endeavours in the field of kidney transplantation in order to create beneficial change in clinical practice and improve patient outcomes. Translational research which engages patients in the investigative process can enhance the likelihood that medical discoveries will have a meaningful impact at the bedside. This article applies current perspectives on translational research and patient engagement to the field of kidney transplantation, illustrating how these approaches have led to significant advancements in the field. It provides further justification for deliberate, targeted efforts to cross-collaborate and incorporate the patient voice into kidney transplant research.

    Non-adherence to the post-transplant regime is a common problem in kidney transplant patients and may lead to rejection or even graft failure. This study investigated attitudes towards the post-transplant regime of immunosuppressive medication among the ever growing population of elderly kidney recipients. Q methodology was used to explore attitude profiles. Participants (> 65 years) were asked to rank-order opinion statements on issues associated with (non-)adherence. The rankings were subject to by-person factor analysis, and the resulting factors were interpreted and described as attitudes. Twenty-six elderly renal transplant recipients participated in the study. All passed the Mini-Mental State Examination. Two attitude profiles were found: (i) satisfied and easy-going (attitude A), and (ii) reserved and concerned (attitude B). Elderly patients with attitude A want to enjoy the new life following their kidney transplant, are not very concerned about having to recommence dialysis, now and then even forget their regime, and do not really worry about it. Elderly patients with attitude B feel more insecure about their kidney transplant, are fairly concerned over issues like rejection or going back on dialysis, and try to adapt their way of life to the regime. One-third of these elderly patients forget their medication at least once a month, but there was no difference between attitude groups. Attitudes about the post-transplant regime differ among elderly patients, implying different needs for assistance, monitoring and risk of non-adherence to the regime. The proportion of elderly patients who forget their medication is considerable, but may be much higher among those with mild and severe cognitive limitations.

    A multicenter comparative study was carried out to investigate the efficacy and safety of hematopoietic stem cell transplantation with conditioning regimens containing melphalan in pediatric patients with acute lymphoblastic leukemia. One hundred twenty three patients at a variety of remission stages were eligible for study participation. Eighty-nine were transplanted with allogeneic grafts and 34 patients with autologous grafts (23 cases with bone marrow and 11 cases with peripheral blood stem cells). Conditioning regimens used were as follows: melphalan and busulfan for 40 patients, melphalan, busulfan and TBI for 44 patients, other regimens for 39 patients. To accelerate engraftment G-CSF (lenograstim) was administered as a 1-hour or 24-hour drip infusion daily at 5 μg/kg from day 5 until hematological recovery. The five year disease free survival (DFS) was 63% for 42 patients at CR1, 41% for 41 patients at CR2 and 33% for 40 patients at other stages. There was no significant difference in the DFS between allogeneic-transplantation and autologous-transplantation in all disease stages. In patients at remission stage for CR1 and CR2, the 5-year DFS by conditioning regimen was 63% for regimen with melphalan and busulfan, 54% for regimen with melphalan, busulfan and TBI and 54% for regimens with melphalan and TBI. There was no significant difference in the DFS between the groups. Serious complications such as renal failure were observed in 11%, veno-occlusive disease in 9%, and interstitial pneumonia in 9%. The most dominating cause of death was relapse in the disease (48% of deaths) which was most commonly observed in autologous transplantation. Contrary to that, treatment related toxic death was the most frequent cause of deaths in allogeneic-transplantation. (author)

    STAT4 (signal transducer and activator of transcription 4) is involved in the regulation of innate and adaptive immune responses. Some studies have suggested that STAT4 may be involved in the immune response after graft transplantation. Several polymorphisms in the STAT4 gene have been identified. The most commonly studied polymorphism in the STAT4 gene is rs7574865. In our study, we examined whether this polymorphism is associated with the early and late functions of renal allografts. A total of 270 recipients of first renal transplants were included in the study. Single nucleotide polymorphisms (SNPs) within the STAT4 gene were genotyped using TaqMan genotyping assays. There were no statistically significant associations between the STAT4 gene rs7574865 polymorphism and delayed graft function, acute rejection, chronic allograft dysfunction, post-transplant diabetes mellitus, or creatinine serum concentrations after transplantation. Our results suggest a lack of association between the STAT4 rs7574865 SNP and kidney allograft function in the Polish population.

    To analyze characteristics and indications for corneal transplantation in patients undergoing penetrating, lamellar, and endothelial keratoplasty in Auckland, New Zealand (NZ). Corneal transplantation data from the NZ National Eye Bank and hospital records of corneal transplant recipients in the Auckland region from January 1, 2000, to December 31, 2009, were collated. Patient demographics, preoperative diagnosis, indication, ocular and medical history, visual acuity, deprivation index, and access to transplantation surgery were analyzed. A total of 941 corneal transplants involving 770 patients were included for analysis. Mean age was 46 years. Age and ethnicity varied according to the transplant indication. A male preponderance and disproportionally high rates of Māori and Pacific ethnicity with a mean age of 30 years were observed in transplants for keratoconus. A total of 67.2% of corneal transplants were completed in the public health system and were associated with higher levels of deprivation than those completed in private facilities. Preoperative visual acuity varied according to the transplant type and indication. The most common clinical indication for corneal transplantation was keratoconus (41.3%), followed by repeat transplantation (21.0%). There was no significant change in the relative proportion of transplant indications in any year over the duration of this study (P = 0.41). A contralateral corneal transplant was present in 24.4% and glaucoma in 12.8% of penetrating keratoplasty recipients. Keratoconus is the leading indication for corneal transplantation in Auckland, NZ, and involves a disproportionately high rate of Māori and Pacific transplant recipients with a male preponderance and comparatively low mean age at the time of surgery.

    Introduction: The drop-off risk for patients awaiting liver transplantation for hepatocellular carcinoma (HCC) is 22%. Transplant liver availability is expected to worsen, resulting in longer waiting times and increased drop-off rates. Our aim was to determine whether chemoembolization can decrease this risk. Patients and Methods: Eighty-seven consecutive HCC patients listed for liver transplant (Milan criteria) underwent statistical comparability adjustments using the propensity score (Wilcoxon, Fisher’s, and chi-square tests). Forty-three nonchemoembolization patients and 22 chemoembolization patients were comparable for Child-Pugh and Model for End-Stage Liver Disease scores, tumor size and number, alpha fetoprotein (AFP) levels, and cause of cirrhosis. We calculated the risk of dropping off the transplant list by assigning a transplant time to those who dropped off (equal probability with patients who were on the list longer than the patient in question). The significance level was obtained by calculating the simulation distribution of the difference compared with the permutations of chemoembolization versus nonchemoembolization assignment of the patients. Kaplan–Meier estimators (log-rank test) were used to determine survival rates. Results: Median follow-up was 187 ± 110 weeks (range 38 to 435, date of diagnosis). The chemoembolization group had an 80% drop-off risk decrease (15% nonchemoembolization versus 3% chemoembolization, p = 0.04). Although survival was better for the chemoembolization group, it did not reach statistical significance. Two-year survival for the nonchemoembolization and chemoembolization group was 57.3% ± 7.1% and 76.0% ± 7.9%, respectively (p = 0.078). Conclusions: Chemoembolization appears to result in a significant decrease in the risk of dropping off liver transplant list for patients with HCC and results in a tendency toward longer survival.

    Lung transplantation has become in recent years a therapeutic option for infantswith terminal lung disease with similar results to transplantation in adults.In Spain, since 1996 114 children lung transplants have been performed; this corresponds to3.9% of the total transplant number.The most common indication in children is cystic fibrosis, which represents between 70-80% of the transplants performed in adolescents. In infants common indications areinterstitial lung disease and pulmonary hypertension.In most children a sequential double lung transplant is performed, generally with the help ofextracorporeal circulation. Lung transplantation in children presents special challenges in monitoring and follow-up, especially in infants, given the difficulty in assessing lung function and performing transbronchial biopsies.There are some more specific complications in children like postransplant lymphoproliferative syndrome or a greater severity of respiratory virus infections .After lung transplantation children usually experiment a very important improvement in their quality of life. Eighty eight per cent of children have no limitations in their activity after 3 years of transplantation.According to the registry of the International Society for Heart & Lung Transplantation (ISHLT) survival at 5 years of transplantation is 54% and at 10 years is around 35%.

    Digital subtraction angiography (DSA) was performed in 53 of 417 patients with renal transplants. The incidence of clinical apparent vascular complications was 9.1% of all patients with renal transplants (38/417). The most frequent vascular disorders were formed by arterial stenoses at 5.0% of the cases followed by arterial obstructions in 1.7% of the patients. Rare vascular complications were arteriovenous fistulas (0.7%), aneurysms (0.5%) and venous thrombose (0.2%). Because of the high diagnostic value of intraarterial DSA, all patients with renal transplants with a complicated postoperative course should be eligible for angiographic control. In case of a suspected vascular disorder intraarterial DSA should be performed at an early stage. (orig.)

    Full Text Available Although cases of leishmaniasis co-infection have been described in acquired immunodeficiency syndrome patients as well as those who have undergone organ transplants, to our knowledge, the present report is the first documented case of simultaneous cutaneous, visceral and ocular leishmaniasis due to Leishmania (Viannia braziliensis in a transplant patient. The patient had been using immunosuppressive drugs since receiving a transplanted kidney. The first clinical signs of leishmaniasis included fever, thoracic pain, hepatosplenomegaly, leucopenia and anemia. The cutaneous disease was revealed by the presence of amastigotes in the skin biopsy. After three months, the patient presented fever with conjunctive hyperemia, intense ocular pain and low visual acuity. Parasites isolated from iliac crest, aqueous humor and vitreous body were examined using a range of molecular techniques. The same strain of L. (V. braziliensis was responsible for the different clinical manifestations. The immunosuppressive drugs probably contributed to the dissemination of Leishmania.

    Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

    Organ procurement in China has been criticized because of its reliance on executed prisoners as donors. We aimed to assess the influence of perceptions about organ procurement practices in China on domestic patient care decisions. Methods An anonymous Internet administered case-based questionnaire was used to survey an sample of healthcare professionals with affiliations to hepatology and transplantation professional societies. Results Of 674 completed surveys, the vast majority (93%) of the respondents were physicians, surgeons or allied transplant professionals actively caring for liver transplant patients and 81% practiced in the United States (US). A strong majority believed procurement practices were ethically sound in the US and Europe (87% and 73%) but fare fewer believed that procurement practices were ethically sound in China (4%, pethical standards of organ procurement in China predicted patient-care decisions. The majority would provide post-transplantation care for patients who underwent liver transplantation at another domestic center, in a foreign country and in China (90%,78%,63%, respectively, pprocurement practices in China were more reluctant to do so (pprocurement practices in China which influenced their patient care decision-making.

    Organ transplantation is now an accepted method of therapy for treating patients with end stage failure of kidneys, liver, heart or lung. Nuclear Medicine may provide functional data and semi-quantitative parameters. However, one serious factor that hampers the use of nuclear medicine procedures in transplant patients is the general clinical concern about radiation exposure to the patient. This lead the researcher to discuss the effective doses and radiation dosimetry associated with radionuclide procedures used in the management and follow-up of transplant patients. A simple way to place the risk associated with Nuclear Medicine studies in an appropriate context is to compare the dose with that received from more familiar source of exposure such as from a diagnostic X-ray procedure. The radiation dose for the different radiopharmaceuticals used to study transplant organ function ranges between 0.1 and 5.3 mSv which is comparable to X-ray procedures with the exception of 201 Tl and 111 In-antimyosin. Thus Nuclear Medicine studies do not bear a higher radiation risk than the often used X-ray studies in transplant patients

    Composite tissue allotransplantion has been the latest addition to reconstructive plastic surgery of limbs and faces. These techniques have opened up a new paradigm in reconstruction. However, plastic surgeons will have to face a new patient population that receives the application of vascularised tissue allografts and immunosuppression. Secondary surgery may be necessary in this population, especially in the transplanted tissues, to improve aesthetics and function following the transplant, although little is known regarding the exact clinical protocol to be followed and the feasibility of standard plastic surgery techniques on transplanted tissues. We present our experience of a LeFort I osteotomy, limited ritidectomy and blepharoplasty in a full-face transplant recipient.

    Full Text Available Preparation for heart transplant commonly includes booklets, instructional videos, personalized teaching sessions, and mentorship. This paper explores heart transplant recipients’ thoughts on their preparation and support through the transplant process. Twenty-five interviews were audio-/videotaped capturing voice and body language and transcribed verbatim. Coding addressed language, bodily gesture, volume, and tone in keeping with our visual methodology. Recipients reported that only someone who had a transplant truly understands the experience. As participants face illness and life-altering experiences, maintaining a positive attitude and hope is essential to coping well. Healthcare professionals provide ongoing care and reassurance about recipients’ medical status. Mentors, family members, and close friends play vital roles in supporting recipients. Participants reported that only heart transplant recipients understood the experience, the hope, and ultimately the suffering associated with living with another persons’ heart. Attention needs to be focused not solely on the use of teaching modalities, but also on the development of innovative support networks. This will promote patient and caregiver engagement in self-management. Enhancing clinicians’ knowledge of the existential aspects of transplantation will provide them with a nuanced understanding of the patients’ experience, which will ultimately enhance their ability to better prepare and support patients and their caregivers.

    2015-01-01

    Type 1 diabetes mellitus is caused by the autoimmune destruction of pancreatic beta (β) cells, resulting in severe insulin deficiency. Islet transplantation is a β-cell replacement therapeutic option that aims to restore glycemic control in patients with type 1 diabetes. The objective of this study was to determine the clinical effectiveness of islet transplantation in patients with type 1 diabetes, with or without kidney disease. We conducted a systematic review of the literature on islet transplantation for type 1 diabetes, including relevant health technology assessments, systematic reviews, meta-analyses, and observational studies. We used a two-step process: first, we searched for systematic reviews and health technology assessments; second, we searched primary studies to update the chosen health technology assessment. The Assessment of Multiple Systematic Reviews measurement tool was used to examine the methodological quality of the systematic reviews and health technology assessments. We assessed the quality of the body of evidence and the risk of bias according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. Our searched yielded 1,354 citations. One health technology assessment, 11 additional observational studies to update the health technology assessment, one registry report, and four guidelines were included; the observational studies examined islet transplantation alone, islet-after-kidney transplantation, and simultaneous islet-kidney transplantation. In general, low to very low quality of evidence exists for islet transplantation in patients with type 1 diabetes with difficult-to-control blood glucose levels, with or without kidney disease, for these outcomes: health-related quality of life, secondary complications of diabetes, glycemic control, and adverse events. However, high quality of evidence exists for the specific glycemic control outcome of insulin independence compared with

    Full Text Available Abstract Background Patients with end stage liver disease are characteristically malnourished which is associated with poor outcome. Formulas enriched with arginine, ω-3 fatty acids, and nucleotides, "immunonutrients", potentially improve their nutritional status. This study is designed to evaluate the clinical outcome of long-term "immunonutrition" of patients with end-stage liver disease while on the waiting list for liver transplantation. Methods/design A randomized controlled double blind multi-center clinical trial with two parallel groups comprising a total of 142 newly registered patients for primary liver transplantation has been designed to assess the safety and efficacy of the long-term administration of ORAL IMPACT®, an "immunonutrient" formula, while waiting for a graft. Patients will be enrolled the day of registration on the waiting list for liver transplantation. Study ends on the day of transplantation. Primary endpoints include improved patients' nutritional and physiological status, as measured by mid-arm muscle area, triceps skin fold thickness, grip strength, and fatigue score, as well as patients' health related quality of life. Furthermore, patients will be followed for 12 postoperative weeks to evaluate anabolic recovery after transplantation as shown by reduced post-transplant mechanical ventilation, hospital stay, wound healing, infectious morbidities (pneumonia, intraabdominal abscess, sepsis, line sepsis, wound infection, and urinary tract infection, acute and chronic rejection, and mortality. Discussion Formulas enriched with arginine, ω-3 fatty acids, and nucleotides have been proven to be beneficial in reducing postoperative infectious complications and length of hospital stay among the patients undergoing elective gastrointestinal surgery. Possible mechanisms include downregulation of the inflammatory responses to surgery and immune modulation rather than a sole nutritional effect. Trial registration Clinical

  20. Risk factors for frequent readmissions and barriers to transplantation in patients with cirrhosis.

    Full Text Available Hospital readmission rate is receiving increasing regulatory scrutiny. Patients with cirrhosis have high hospital readmissions rates but the relationship between frequent readmissions and barriers to transplantation remains unexplored. The goal of this study was to determine risk factors for frequent readmissions among patients with cirrhosis and identify barriers to transplantation in this population.We retrospectively reviewed medical records of 587 patients with a confirmed diagnosis of cirrhosis admitted to a large tertiary care center between May 1, 2008 and May 1, 2009. Demographics, clinical factors, and outcomes were recorded. Multivariate logistic regression was performed to identify risk factors for high readmission rates. Transplant-related factors were assessed for patients in the high readmission group.The 587 patients included in the study had 1557 admissions during the study period. A subset of 87 (15% patients with 5 or more admissions accounted for 672 (43% admissions. The factors associated with frequent admissions were non-white race (OR = 2.45, p = 0.01, diabetes (OR = 2.04, p = 0.01, higher Model for End-Stage Liver Disease (MELD score (OR = 35.10, p30 and younger age (OR = 0.98, p = 0.02. Among the 87 patients with ≥5 admissions, only 14 (16% underwent liver transplantation during the study period. Substance abuse, medical co-morbidities, and low (<15 MELD scores were barriers to transplantation in this group.A small group of patients with cirrhosis account for a disproportionately high number of hospital admissions. Interventions targeting this high-risk group may decrease frequent hospital readmissions and increase access to transplantation.

  1. Living-related liver transplantation for patients with fulminant and subfulminant hepatic failure.

    1999-12-01

    The prognosis for patients with fulminant (FHF) or subfulminant hepatic failure (SFHF) has improved since the introduction of liver transplantation. However, the death rate of patients awaiting liver transplantation is high, possibly because of the difficulty in obtaining grafts in a timely manner, given the relative shortage of cadaveric donors. Between June 1990 and June 1999, 106 patients underwent living-related liver transplantation (LRLT) at Shinshu University Hospital. Among them, 8 patients had FHF and 6 had SFHF; these 14 patients are the subjects of this report. The graft volumes (GV) ranged from 231 mL to 625 mL, corresponding to 35% to 105% of the recipients' standard liver volume (SLV). The postoperative courses of all donors were uneventful. Following liver transplantation, all grafts functioned favorably, with normalization of serum total bilirubin within 3 to 5 days and normalization of coagulation profiles within 4 to 7 days. Thirteen of the 14 recipients are still alive. The actuarial 6-month, 1-year, and 5-year survival rates were 100%, 90%, and 90%, respectively. In the present study, when the ratio of the GV to the recipient's SLV was more than 35%, the graft was able to support the patient's metabolic demand after liver transplantation for FHF or SFHF. Because of the urgent nature of liver transplantation in this clinical condition, concerns over informed consent may be even greater than for elective LRLT. Nevertheless, the high success rate and low donor risk may justify this option for pediatric patients, as well as for a limited population of adult patients suffering from FHF or SFHF.

    Mooren's ulcer is a severe ulcerative inflammation of the cornea. The exact pathogenesis remains unclear. Therefore many therapies of Mooren's ulcer are recommended in literature. To shed more light on the ongoing question of optimal treatment of severe progressive Mooren's ulcer, we here report on a retrospective case series of patients treated with systemic immunosuppressive therapy and additional amniotic membrane transplantation. Medical records from seven patients (eleven eyes), 4 male and 3 female, with severe progressive Mooren's ulcer were analysed retrospectively. The mean follow up was 88.4 ± 80.8 months (range 12-232 month). A HLA-typing was performed in all patients. A systemic immunosuppressive therapy was administered in all patients. The amniotic membrane was transplanted after the base of the ulcer was resected. Multiple amniotic membrane transplantations were necessary in six patients. The visual outcome of all patients was poor. No patient achieved a visual acuity better than 20/630 Snellen chart. Five patients were positive for HLA-DQ2 and four patients were positive for HLA-DR17(3). The aggressive and highly inflammatory form of Mooren's ulcer is difficult to treat and the progression of the disease is hard to influence positively even under systemic immunosuppressive therapy. Therefore, the main intention of therapy is to achieve a stable epithelialized corneal surface without the risk of perforation. Amniotic membrane transplantation is not able to cure severe forms of Mooren's ulcer. However it supports the immunosuppressive therapy in acute situations as in critical corneal thinning.

    Pulmonary fibrosis is a progressive, fatal manifestation of Hermansky-Pudlak syndrome (HPS). Some patients with advanced HPS pulmonary fibrosis undergo lung transplantation despite their disease-associated bleeding tendency; others die while awaiting donor organs. The objective of this study is to determine the clinical management and outcomes of a cohort with advanced HPS pulmonary fibrosis who were evaluated for lung transplantation. Six patients with HPS-1 pulmonary fibrosis were evaluated at the National Institutes of Health Clinical Center and one of two regional lung transplant centers. Their median age was 41.5 years pre-transplant. Three of six patients died without receiving a lung transplant. One of these was referred with end-stage pulmonary fibrosis and died before a donor organ became available, and donor organs were not identified for two other patients sensitized from prior blood product transfusions. Three of six patients received bilateral lung transplants; they did not have a history of excessive bleeding. One patient received peri-operative desmopressin, one was transfused with intra-operative platelets, and one received extracorporeal membrane oxygenation and intra-operative prothrombin complex concentrate, platelet transfusion, and desmopressin. One transplant recipient experienced acute rejection that responded to pulsed steroids. No evidence of chronic lung allograft dysfunction or recurrence of HPS pulmonary fibrosis was detected up to 6 years post-transplant in these three lung transplant recipients. In conclusion, lung transplantation and extracorporeal membrane oxygenation are viable options for patients with HPS pulmonary fibrosis. Alloimmunization in HPS patients is an important and potentially preventable barrier to lung transplantation; interventions to limit alloimmunization should be implemented in HPS patients at risk of pulmonary fibrosis to optimize their candidacy for future lung transplants.

    High levels of circulating EBV load are used as a marker of post-transplant lymphoproliferative disorders (PTLD). There is no consensus regarding the threshold level indicative of an increase in peripheral EBV DNA. The aim of the study was to clinically validate a developed EBV quantification assay for early PTLD detection. Transversal study: paired peripheral blood mononuclear cells (PBMC), plasma and oropharyngeal lymphoid tissue (OLT) from children undergoing a solid organ transplant with (n=58) and without (n=47) PTLD. Retrospective follow-up: 71 paired PBMC and plasma from recipients with (n=6) and without (n=6) PTLD history. EBV load was determined by real-time PCR. The diagnostic ability to detect all PTLD (categories 1-4), advanced PTLD (categories 2-4) or neoplastic PTLD (categories 3 and 4) was estimated by analyzing the test performance at different cut-off values or with a load variation greater than 0.5log units. The higher diagnostic performance for identifying all, advanced or neoplastic PTLD, was achieved with cut-off values of 1.08; 1.60 and 2.47log EBVgEq/10(5) PBMC or 2.30; 2.60; 4.47loggEq/10(5) OLT cells, respectively. EBV DNA detection in plasma showed high specificity but low (all categories) or high (advanced/neoplastic categories) sensitivity for PTLD identification. Diagnostic performance was greater when: (1) a load variation in PBMC or plasma was identified; (2) combining the measure of EBV load in PBMC and plasma. The best diagnostic ability to identify early PTLD stages was achieved by monitoring EBV load in PBMC and plasma simultaneously; an algorithm was proposed.

    Introduction: Malignancy is a late cause of mortality in heart transplant recipients. It is unknown if screening computed tomography scan would lead to early detection of such malignancies or serious vascular anomalies post heart transplantation. Methods: This is a single center observational study of patients undergoing surveillance computed tomography of chest, abdomen and pelvis atleast 5 years after transplantation. Abnormal findings, included pulmonary nodules, lymphadenopathy and intra-thoracic and intra-abdominal masses and vascular anomalies such as abdominal aortic aneurysm. The clinical follow up of each of these major abnormal findings is summarized. Results: A total of 63 patients underwent computed tomography scan of chest, abdomen and pelvis at least 5 years after transplantation. Of these, 54 (86%) were male and 9 (14%) were female. Mean age was 52 ± 9.2 years. Computed tomography revealed 1 lung cancer (squamous cell) only. Non specific pulmonary nodules were seen in 6 patients (9.5%). The most common incidental finding was abdominal aortic aneurysms (N = 6 (9.5%)), which necessitated follow up computed tomography (N = 5) or surgery (N = 1). Mean time to detection of abdominal aortic aneurysms from transplantation was 14.6 ± 4.2 years. Mean age at the time of detection of abdominal aortic aneurysms was 74.5 ± 3.2 years. Conclusion: Screening computed tomography scan in patients 5 years from transplantation revealed only one malignancy but lead to increased detection of abdominal aortic aneurysms. Thus the utility is low in terms of detection of malignancy. Based on this study we do not recommend routine computed tomography post heart transplantation.

    Medication adherence is essential in kidney transplant recipients to reduce the risk of rejection and subsequent allograft loss. The aim of this study was to delineate what 'usual care' entails, in relation to medication management, for adult kidney transplant recipients. An online survey was developed to explore how nephrologists promote and assess medication adherence, the management of prescriptions, the frequency of clinic appointments and the frequency of clinical screening tests. Nephrologists from all acute kidney transplant units in Victoria, Australia, were invited to participate. Data were collected between May and June 2014. Of 60 nephrologists invited to participate, 22 completed the survey (response rate of 36.6%). Respondents had a mean age of 49.1 ± 10.1 years, with a mean of 20.1 ± 9.9 years working in nephrology and 14 were men. Descriptive analysis of responses showed that nephrologists performed frequent screening for kidney graft dysfunction that may indicate medication non-adherence, maintained regular transplant clinic visits with patients and emphasized the importance of medication education. However, time constraints during consultations impacted on extensive patient education and the long-term medication follow-up support was often delivered by the renal transplant nurse coordinator or pharmacist. This study highlighted that nephrologists took an active approach in the medication management of kidney transplant recipients, which may assist with facilitating long-term graft survival. Ultimately, promoting medication adherence needs to be patient centred, involving an interdisciplinary team of nephrologists, pharmacists and renal transplant nurse coordinators, working together with the patient to establish optimal adherence. © 2015 John Wiley & Sons, Ltd.

    It is established that blood transfusions will promote sensitization to human leucocyte antigen (HLA) antigens, increase time spent waiting for transplantation and may lead to higher rates of rejection. Less is known about how perioperative blood transfusion influence patient and graft outcome. This study aims to establish if there is an association between perioperative blood transfusion and graft or patient survival.

    This study evaluates hand hygiene behavior of health care workers in a German university hospital stratified for treatment of special patient groups (eg, transplant patients). From 2008 to 2010, comprehensive education and training of all health care workers was implemented to improve hand hygiene compliance. Consumption rates of alcohol-based hand rub and gloves were collected and evaluated. Of the 5,647 opportunities of hand disinfection evaluated, 1,607 occurred during care for transplant patients. To our knowledge, this is the largest survey of hand hygiene compliance in special patient groups on intensive care units in a university hospital in Germany. Health care workers on surgical intensive care units showed lower hand hygiene compliance compared with health care workers on other types of intensive care units. Compliance toward hand hygiene was significantly higher on hemato-oncologic and pediatric wards. In general, hand disinfection was performed significantly more frequently after an intervention than before (P hand hygiene compliance when caring for transplant patients or other patients (odds ratio, 1.16; 95% confidence interval: 0.95-1.42). Nurse's and physician's hand hygiene compliance improved because of education. Hand hygiene compliance is not increased in the care for transplant patients (despite their predisposition for nosocomial infections) compared with other patients. Additional studies will be necessary to further investigate these findings. Copyright © 2013 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Mosby, Inc.

    A patient with Marfan syndrome with previous Bentall operation for mitral and tricuspid valve repair, required orthotopic cardiac transplantation for end stage cardiomyopathy. Postoperatively he suffered type-B aortic dissection, despite normal aortic diameters. Following sudden increase of aortic diameters, two years later, he underwent successful stent graft implantation. In patients with Marfan syndrome, post transplantation morbidity is high, with a 40% incidence of thoracic aortic dissection. This case highlights the potential of endovascular approach for treating post-transplantation aortic dissection.

    Full Text Available Purpose:Renal transplantation significantly improves quality of life compared to hemodialysis in patients with end-stage renal failure. In end-stage renal failure anesthetic technique should be planned carefully, due to changes in volume distribution, drug metabolism, excretion. Results of total intravenous anesthesia, inhalation anesthesia, regional techniques are being investigated. Aim of this study was to present our experience in total intravenous anesthesia in 77 patients, who underwent live and cadaveric donor renal transplantation at Baskent University Faculty of Medicine Adana Teaching and Research Center.

    Survival for patients with idiopathic pulmonary fibrosis (IPF) and high lung allocation score (LAS) values may be significantly reduced in comparison to those with lower LAS values. To evaluate outcomes for high-risk IPF patients as defined by LAS values ≥46 (N=42) versus recipients with LAS values pulmonary complications was increased for the higher LAS group versus recipients with LAS <46, 30-day mortality and actuarial survival did not differ between the two cohorts. Although lung transplantation in patients with IPF and high LAS values is associated with increased risk of early post-transplant complications, long-term post-transplant survival for our high-LAS cohort was equivalent to that for the lower LAS recipients.

The inclusion of the patient’s perspective may play an important role in the assessment of the effectiveness of lung transplantation. Patient perspectives are assessed by patient-reported outcome measures, including HRQL measures. We describe how patients’ HRQL among different diagnosis groups can be used by clinicians to monitor and evaluate the outcomes associated with transplantation.Methods: Consecutive lung transplant recipients attending the lung transplant outpatient clinic in a tertiary institution completed the 15-item Health Utilities Index (HUI questionnaire on a touchscreen computer. The results were available to clinicians at every patient visit. The HUI3 covers a range of severity and comorbidities in eight dimensions of health status. Overall HUI3 scores are on a scale in which dead = 0.00 and perfect health = 1.00; disability categories range from no disability = 1 to severe disability <0.70. Single-attribute and overall HUI3 scores were used to compare patients’ HRQL among different diagnosis groups. Random-effect models with time since transplant as a random variable and age, gender, underlying diagnoses, infections, and broncholitis obliterans syndrome as fixed variables were built to identify determinants of health status at 2-years posttransplantation.Results: Two hundred and fourteen lung transplant recipients of whom 61% were male with a mean age of 52 (19–75 years were included in the study.

    In total joint arthroplasty (TJA) literature, there is a paucity of large cohort studies comparing chronic kidney disease (CKD) and end-stage renal disease (ESRD) vs non-CKD/ESRD patients. Thus, the purposes of this study were (1) to identify inhospital complications and mortality in CKD/ESRD and non-CKD/ESRD patients and (2) compare inhospital complications and mortality between dialysis and renal transplantation patients undergoing TJA. We queried the Nationwide Inpatient Sample database for patients with and without diagnosis of CKD/ESRD and those with a renal transplant or on dialysis undergoing primary or revision total knee or hip arthroplasty from 2007 to 2011. Patient comorbidities were identified using the Elixhauser comorbidity index. International Classification of Diseases, Ninth Revision, codes were used to identify postoperative surgical site infections (SSIs), wound complications, deep vein thrombosis, and transfusions. Chronic kidney disease/ESRD was associated with greater risk of SSIs (odds ratio [OR], 1.4; Prenal transplant patients. Chronic kidney disease/ESRD patients had a greater risk of SSIs and wound complications compared to those without renal disease, and the risk of these complications was even greater in CKD/ESRD patients receiving dialysis. These findings emphasize the importance of counseling CKD patients about higher potential complications after TJA, and dialysis patients may be encouraged to undergo renal transplantation before TJA.

    Full Text Available ABSTRACT Introduction: Patients submitted to hematopoietic stem cell transplantation have an increased risk of Clostridium difficile infection and multiple risk factors have been identi- fied. Published reports have indicated an incidence from 9% to 30% of transplant patients however to date there is no information about infection in these patients in Chile. Methods: A retrospective analysis was performed of patients who developed C. difficile infection after hematopoietic stem cell transplantations from 2000 to 2013. Statistical analysis used the Statistical Package for the Social Sciences software. Results: Two hundred and fifty patients were studied (mean age: 39 years; range: 17-69, with 147 (59% receiving allogeneic transplants and 103 (41% receiving autologous trans- plants. One hundred and ninety-two (77% patients had diarrhea, with 25 (10% cases of C. difficile infection being confirmed. Twenty infected patients had undergone allogeneic trans- plants, of which ten had acute lymphoblastic leukemia, three had acute myeloid leukemia and seven had other diseases (myelodysplastic syndrome, chronic myeloid leukemia, severe aplastic anemia. In the autologous transplant group, five patients had C. difficile infection; two had multiple myeloma, one had amyloidosis, one had acute myeloid leukemia and one had germinal carcinoma. The overall incidence of C. difficile infection was 4% within the first week, 6.4% in the first month and 10% in one year, with no difference in overall survival between infected and non-infected groups (72.0% vs. 67.6%, respectively; p-value = 0.56. Patients infected after allogeneic transplants had a slower time to neutrophil engraftment compared to non-infected patients (17.5 vs. 14.9 days, respectively; p-value = 0.008. In the autologous transplant group there was no significant difference in the neutrophil engraftment time between infected and non-infected patients (12.5 days vs. 11.8 days, respectively; p

    Adolescent and young adult kidney transplant recipients have worse graft outcomes than older and younger age groups. Difficulties in the process of transition, defined as the purposeful, planned movement of adolescents with chronic health conditions from child to adult-centered health care systems, may contribute to this. Improving the process of transition may improve adherence post-transfer to adult care services. The purpose of this study is to investigate whether a kidney transplant transfer clinic for adolescent and young adult kidney transplant recipients transitioning from pediatric to adult care improves adherence post-transfer. We developed a joint kidney transplant transfer clinic between a pediatric kidney transplant program, adult kidney transplant program, and adolescent medicine at two academic health centers. The transfer clinic facilitated communication between the adult and pediatric transplant teams, a face-to-face meeting of the patient with the adult team, and a meeting with the adolescent medicine physician. We compared the outcomes of 16 kidney transplant recipients transferred before the clinic was established with 16 patients who attended the clinic. The primary outcome was a composite measure of non-adherence. Non-adherence was defined as either self-reported medication non-adherence or displaying two of the following three characteristics: non-attendance at clinic, non-attendance for blood work appointments, or undetectable calcineurin inhibitor levels within 1 year post-transfer. The two groups were similar at baseline, with non-adherence identified in 43.75 % of patients. Non-adherent behavior in the year post-transfer, which included missing clinic visits, missing regular blood tests, and undetectable calcineurin inhibitor levels, was significantly lower in the cohort which attended the transfer clinic (18.8 versus 62.5 %, p = 0.03).

    Long-term immunosuppressive therapy after renal transplantation increases the risk of developing malignancy. The aim of this study was to determine the demographic parameters and immunosupression protocol in kidney transplant recipients with and without malignancy. This case-control study was undertaken on 12 renal transplant recipients with malignancy and 48 without malignancy at The Shahid Beheshti Kidney Transplantation Center in Babol (north of Iran). Data including age, gender, number of anti-rejection therapies and immunosupression regimen were recorded and analyzed with SPSS and Mann-Whitney Fisher's exact t-test. P value 0.05). Males were signi-ficantly more affected with malignancy compared to females (P < 0.05). Our study shows that there was no significant correlation between age at transplantation, duration of immunosupression treatment and number of anti-rejection therapies and occurrence of post-renal transplantation malignancy; however, the prevalence of malignancy was significantly higher in male patients. The most common malignancy seen was Kaposi's sarcoma followed by lymphoma (Author).

    The use of belatacept is not yet approved for maintenance kidney-transplant patients. This retrospective multicenter European study aimed to assess the efficacy and safety of conversion to belatacept in a large cohort of patients in a real-life setting, and to identify the predictive factors for improved kidney function after the switch. Two-hundred and nineteen maintenance kidney-transplant patients from 5 European kidney-transplant centers were converted to belatacept at 21.2 (0.1-337.1) months posttransplantation, mainly because of impaired kidney function. Thirty-two patients were converted to belatacept within the first 3 months posttransplantation. The mean duration of follow-up was 21.9±20.2 months. The actuarial rate of patients still on belatacept-based therapy was 77.6%. Mean estimated glomerular-filtration rate (eGFR) increased from 32±16.4 at baseline to 38±20 mL/min/1.73 m (ppredictive factor for a significant increase in eGFR (of 5 and 10 mL/min/1.73 m at 3 and 12 months after the switch, respectively). Eighteen patients (8.2%) presented with an acute-rejection episode after conversion; 3 developed a donor-specific antibody (DSA). Overall efficacy and safety were good, including for the 35 patients that had a DSA at conversion. The conversion to belatacept was effective, especially when performed early after transplantation.

    Renal failure is a common finding in patients undergoing orthotopic liver transplantation. The aim of the present study was to evaluate the incidence, prognostic value of pre, intra and postoperative factors and severity of renal dysfunction in patients who undergo liver transplantation. Therefore, the records of 38 consecutive adult patients were reviewed. Renal failure was defined arbitrarily as an increase in creatinine (> 1.5 mg/dl) and/or blood urea (> 80 mg/dl). Three patients were excluded of the final analysis (1 acute liver failure and 2 with a survival lower than 72 hs.) Twenty one of the 35 patients has renal failure after orthotopic liver transplantation. Six of these episodes developed early, having occurred within the first 6 days. Late renal impairment occurred in 15 patients within the hospitalization (40 +/- 10 days) (Mean +/- SD). In he overall series, liver function, evaluated by Child-Pugh classification, a higher blood-related requirements and cyclosporine levels were observed more in those who experienced renal failure than those who did not (p renal failure was related with preoperative (liver function) and intraoperative (blood requirements) factors and several causes (nephrotoxic drugs and graft failure) other than cyclosporine were present in patients who developed late renal impairment. No mortality. No mortality was associated with renal failure. We conclude that renal failure a) is a common finding after liver transplantation, b) the pathogenesis of this complication is multifactorial and, c) in not related with a poor outcome.

    Posterior reversible encephalopathy syndrome (PRES) is an uncommon but well-known complication after transplantation diagnosed by characteristic radiological features. As limited data on this complex syndrome exist we sought to better define the incidence, clinical presentation and risk factors for PRES in liver transplant (LTx) patients. We conducted a retrospective analysis of 1923 adult LTx recipients transplanted between 2000 and 2010. PRES was diagnosed radiologically in 19 patients (1%), with 84% of cases occurring within 3 months post-LTX. We compared this cohort of PRES patients to 316 other LTx recipients also requiring radiographic imaging within 3 months after LTx for neurological symptoms. Seizure was the most common clinical manifestation in the PRES group (88% vs. 16%, pliver disease and infection/sepsis. These factors may be related to a common pathway of vascular dysregulation/damage that appears to characterize this complex syndrome. Intracranial bleeding and seizures may be the end result of these phenomena. The relationship of these associated factors to the hypothesized pathophysiology of PRES is discussed. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Objective: The aim of this study was to determine the effectiveness and safety of percutaneous laser ablation for the treatment of cirrhotic patients with hepatocellular carcinoma awaiting liver transplantation. Materials and methods: The data of 9 male cirrhotic patients (mean age 50 years, range 45-60 years) with 12 biopsy proven nodules of hepatocellular carcinoma (mean diameter 2.0 cm, range 1.0-3.0 cm) treated by laser ablation before liver transplantation between June 2000 and January 2006 were retrospectively reviewed. Laser ablation was carried out by inserting 300 nm optical fibers through 21-Gauge needles (from two to four) positioned under ultrasound guidance into the target lesions. A continuous wave Neodymium:Yttrium Aluminium Garnet laser was used. Transarterial chemoembolization prior to liver transplantation was performed in two incompletely ablated tumors. Results: No procedure-related major complications were recorded. During the waiting time to liver transplantation local tumor progression after ablation occurred in 3 nodules (25%). At histological examination of the explanted livers complete necrosis was found in 8 nodules (66.7%, all treated exclusively with laser ablation), partial necrosis >50% in 3 nodules (25%), and partial necrosis <50% in 1 nodule. Conclusion: In patients with cirrhotic livers awaiting liver transplantation, percutaneous laser ablation is safe and effective for the management of small hepatocellular carcinoma.

    Posttransplant lymphoproliferative disorder (PTLD) can be resolved in many transplant patients by the reduction or cessation of immunosuppression, after which many grafts continue to function as the result of a form of operational tolerance. When graft function deteriorates, retransplantation may...... be an option. Cytokines such as interleukin (IL)-10 and IL-18 may play a role in PTLD tolerance induction and tumor regression. We report long-term follow-up on the duration of graft tolerance and the course of retransplantation in a series of patients who underwent kidney transplantation and demonstrated PTLD...

    Based on evidence gained from ten patients of allogeneic bone marrow transplantation (BMT) and eight patients of autologous BMT, recent knowledge on literatures of BMT and total body irradiation (TBI) is summarized. Interstitial pneumonia after BMT has a strong correlation with TBI. Low dose-rate and fractionation of TBI are seemed to reduce the lung injury, thereby reducing the incidence of nonleukemia deaths. BMT is applied to not only acute leukemia, malignant lymphoma and solid tumors but also to chronic leukemia. It is emphasized that several of the important prognostic factors are within the control of the transplantation team.

    20 year old post renal transplant patient developed recurrent episodes of seizure. MRI revealed focal lesion in right parieto-occipital lobe with perilesional edema. FDG PET-CT revealed multiple hypermetabolic lesions in bilateral cerebral hemisphere. Subsequent biopsy from the lesion demonstrated bradyzoites of Toxoplasma gondii with inflammatory cells and thereby, a confirmatory diagnosis of cerebral toxoplasmosis was made. This case demonstrates the fact that increased FDG uptake in cerebral lesions in post transplant patient should be interpreted with caution and confirmed with histopathological correlation.

    1998-01-01

    Full Text Available The frequency of infection by Cryptosporidium parvum was determined in two groups of renal patients submitted to immunosuppression. One group consisted of 23 renal transplanted individuals, and the other consisted of 32 patients with chronic renal insufficiency, periodically submitted to hemodialysis. A third group of 27 patients with systemic arterial hypertension, not immunosuppressed, was used as control. During a period of 18 months all the patients were submitted to faecal examination to detect C. parvum oocysts, for a total of 1 to 6 tests per patient. The results showed frequencies of C. parvum infection of 34.8%, 25% and 17.4%, respectively, for the renal transplanted group, the patients submitted to hemodialysis and the control group. Statistical analysis showed no significant differences among the three groups even though the frequency of C. parvum infection was higher in the transplanted group. However, when the number of fecal samples containing C. parvum oocysts was taken in account, a significantly higher frequency was found in the renal transplanted group.

    Background Parathyroidectomy is the only curative treatment for tertiary hyperparathyroidism (3HPT). With the introduction of calcimimetics (cinacalcet), parathyroidectomy can sometimes be delayed or avoided. The purpose of this study was to determine the current incidence of utilization of parathyroidectomy in patients with post-transplant 3HPT with the advent of cinacalcet. Method We evaluated renal transplant patients between 1/1/2004-6/30/2012 with a minimum of 24 months follow-up who had persistent allograft function. Patients with an increased serum level of parathyroid hormone (PTH) one year after successful renal transplantation with normocalcemia or hypercalcemia were defined as having 3HPT. A multivariate logistic regression model was constructed to determine factors associated with undergoing parathyroidectomy. Results We identified 618 patients with 3HPT, only 41 (6.6%) of whom underwent parathyroidectomy. Patients with higher levels of serum calcium (p<0.001) and PTH (p=0.002) post-transplant were more likely to be referred for parathyroidectomy. Importantly, those who underwent parathyroidectomy had serum calcium and PTH values distributed more closely to the normal range on most recent follow-up. Parathyroidectomy was not associated with rejection (p=0.400) or with worsened allograft function (p=0.163). Conclusion Parathyroidectomy appears to be underutilized in patients with 3HPT at our institution. Parathyroidectomy is associated with high cure rates, improved serum calcium and PTH levels, and is not associated with rejection. PMID:26603850

    Diabetes is a powerful predictor of adverse events in patients undergoing percutaneous coronary intervention. Drug-eluting stents reduce restenosis rates compared with bare metal stents; however, controversy remains regarding which drug-eluting stents provides greater benefit in patients with diabetes. Accordingly, we compared the safety and efficacy of sirolimus-eluting stents (SES) with paclitaxel-eluting stents (PES) among diabetic patients in a contemporary registry. Using the National Heart, Lung, and Blood Institute Dynamic Registry, we evaluated 2-year outcomes of diabetic patients undergoing percutaneous coronary interventions with SES (n=677) and PES (n=328). Clinical and demographic characteristics, including age, body mass index, insulin use, left ventricular function, and aspirin/clopidogrel use postprocedure, did not differ significantly between the groups except that PES-treated patients had a greater frequency of hypertension and hyperlipidemia. At the 2-year follow-up, no significant differences were observed between PES and SES with regard to safety or efficacy end points. PES- and SES-treated patients had similar rates of death (10.7% versus 8.2%, P=0.20), death and myocardial infarction (14.9% versus 13.6%, P=0.55), repeat revascularization (14.8% versus 17.8%, P=0.36), and stent thrombosis (1.3% versus 1.3%, P=0.95). After adjustment, no significant differences between the 2 stent types in any outcome were observed. PES and SES are equally efficacious and have similar safety profiles in diabetic patients undergoing percutaneous coronary interventions in clinical practice.

    Despite the importance of pretransplantation outcomes, 1-year posttransplantation survival is typically considered the primary metric of lung transplant center performance in the United States. We designed a novel lung transplant center performance metric that incorporates both pre- and posttransplantation survival time. We performed an ecologic study of 12 187 lung transplant candidates listed at 56 U.S. lung transplant centers between 2006 and 2012. We calculated an "intention-to-treat" survival (ITTS) metric as the percentage of waiting list candidates surviving at least 1 year after transplantation. The median center-level 1-year posttransplantation survival rate was 84.1%, and the median center-level ITTS was 66.9% (mean absolute difference 19.6%, 95% limits of agreement 4.3 to 35.1%). All but 10 centers had ITTS values that were significantly lower than 1-year posttransplantation survival rates. Observed ITTS was significantly lower than expected ITTS for 7 centers. These data show that one third of lung transplant candidates do not survive 1 year after transplantation, and that 12% of centers have lower than expected ITTS. An "intention-to-treat" survival metric may provide a more realistic expectation of patient outcomes at transplant centers and may be of value to transplant centers and policymakers. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Tygon tubing is a co-polymer polyvinyl chloride. This tubing is used throughout the circuit of our heart-lung by-pass machines and had been sterilized by autoclaving or exposure to ethylene oxide gas. Tubing sterilized by autoclaving was noted to have a decrease in tensile strength and the transparency of the tubing was affected. Sterilization by ethylene oxide had the disadvantage that gas was often present in the lumen of the tube when connected to the machine. Lengths of Tygon tubing were sterilized by gamma radiation at varying radiation levels and temperatures. Bacteriological studies were done on the tubing and estimation of tensile strength carried out. We have found that a level of radiation of 2. 5 to 3. 0 Mrad at 20°C produces little or no change in tensile strength and the tubing remains bacteriologically sterile. Tygon tubing sterilized in this way has now been used in over sixty heart-lung by-pass machine operations. (author)

  1. One hundred patients with acute leukemia treated by chemotherapy, total body irradiation, and allogeneic marrow transplantation

    One hundred patients, 54 with acute myelogenous leukemia (AML) and 46 with acute lymphoblastic leukemia (ALL), considered to be in the end stages of their disease, after combination chemotherapy were treated by marrow transplantation. All patients were given a marrow graft from an HLA-identical sibling after receiving 1000-rad total body irradiation (TBI). One group of 43 patients was given cyclophosphamide (CY), 60 mg/kg on each of 2 days, 5 and 4 days before TBI. In a second group of 31 patients, additional chemotherapy was given before CY and TBI. In a third group of 19 patients, BCNU was given before CY and TBI. A fourth group of 7 patients received other chemotherapy regimens before TBI. Six patients died 3 to 17 days after marrow infusion without evidence of engraftment. Ninety-four patients were engrafted rejected and only one patient rejected the graft. Thirteen patients are alive with a marrow graft, on no maintenance antileukemic therapy, and without recurrent leukemia 1--4 1 / 2 yr after transplantation. Three have chronic graft-versus-host disease (GVHD). The relapse rate appeared to be relatively constant over the first 2 yr and was extremely low after that time. Neither survival nor leukemic relapse appeared to be influenced by the type of leukemia nor by the preparative chemotherapy regimen given before TBI. Patients in fair clinical condition at the time of transplantation showed significantly longer survival times than patients in poor condition (p = 0.001). This observation, coupled with the observation that some patients may be cured of their disease, indicates that marrow transplantation should now be undertaken earlier in the management of patients with acute leukemia who have an HLA-matched sibling marrow donor

    Malnutrition is found in almost 100% of patients with end stage liver disease (ESLD) awaiting transplantation and malnutrition before transplantation leads to higher rates of post-transplant complications and worse graft survival outcomes. Reasons for protein energy malnutrition include several metabolic alterations such as inadequate intake, malabsorption, and overloaded expenditure. And also, stress from surgery, gastrointestinal reperfusion injury, immunosuppressive therapy and corticosteriods use lead to delayed bowl function recovery and disorder of nutrients absorption. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by hepatic decompensation. During the acute post-transplant phase, adequate nutrition is required to help support metabolic demands, replenish lost stores, prevent infection, arrive at a new immunologic balance, and promote overall recovery. In a word, it is extremely important to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation (LT). This study review focuses on prevalence, nutrition support, evaluation, and management of perioperative nutrition disorder in patients with ESLD undergoing LT.

    Whether socioeconomic status confers worse outcomes after kidney transplantation is unknown. Its influence on allograft and patient survival following kidney transplantation in Ireland was examined. A retrospective, observational cohort study of adult deceased-donor first kidney transplant recipients from 1990 to 2009 was performed. Those with a valid Irish postal address were assigned a socioeconomic status score based on the Pobal Hasse-Pratschke deprivation index and compared in quartiles. Cox proportional hazards models and Kaplan-Meier survival analysis were used to investigate any significant association of socioeconomic status with patient and allograft outcomes. A total of 1944 eligible kidney transplant recipients were identified. The median follow-up time was 8.2 years (interquartile range 4.4-13.3 years). Socioeconomic status was not associated with uncensored or death-censored allograft survival (hazard ratio (HR) 1.0, 95% confidence interval (CI) 0.99-1.00, P = 0.33 and HR 1.0, 95% CI 0.99-1.00, P = 0.37, respectively). Patient survival was not associated with socioeconomic status quartile (HR 1.0, 95% CI 0.93-1.08, P = 0.88). There was no significant difference among quartiles for uncensored or death-censored allograft survival at 5 and 10 years. There was no socioeconomic disparity in allograft or patient outcomes following kidney transplantation, which may be partly attributable to the Irish healthcare model. This may give further impetus to calls in other jurisdictions for universal healthcare and medication coverage for kidney transplant recipients. © 2015 Asian Pacific Society of Nephrology.

    Portal hypertension secondary to portal vein obstruction following liver transplant occurs in 5%-10% of children. Jejunal varices are uncommon in this group. We present a case series of children with significant GI blood loss, negative upper endoscopy, and jejunal varices detected by CE. Case series of patients who had CE for chronic GI blood loss following liver transplantation. Three patients who had their initial transplants at a median age of 7 months were identified at our institution presenting at a median age of 8 years (range 7-16 years) with a median Hgb of 2.8 g/dL (range 1.8-6.8 g/dL). Upper endoscopy was negative for significant esophageal varices, gastric varices, and bleeding portal gastropathy in all three children. All three patients had significant jejunal varices noted on CE in mid-jejunum. Jejunal varices were described as large prominent bluish vessels underneath visualized mucosa, one with evidence of recent bleeding. The results led to venoplasty of the portal vein in two patients and a decompressive shunt in one patient with resolution of GI bleed and anemia. CE is useful to diagnose intestinal varices in children with portal hypertension and GI bleeding following liver transplant. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The relationship between the use of immunosuppressants in solid-organ transplant patients and oral tissue abnormalities has been recognized. The objective of this study was to determine the state of oral tissue integrity in renal, heart, and liver transplant patients who are on continuous medical and dental control. Forty patients of both sexes were clinically evaluated at the Clinical Hospital of the University of Chile to identify pathologies of oral mucosa, gingival enlargement (GE), decayed, missing, filled teeth (DMFT) index, and salivary flow. The average age of the transplant subjects was 49.4 years, and the age range was 19 to 69 years. Most subjects maintained a good level of oral hygiene, and the rate mean of DMFT was 14.7. The degree of involvement of the oral mucosa and GE was low (10%). Unlike other studies, the frequency of oral mucosal diseases and GE was low despite the fact that these patients were immunosuppressed. Care and continuous monitoring seem to be of vital importance in maintaining the oral health of transplant patients.

    Cancer has become the second most common cause of death in patients after organ transplantation. Among all cancers arising de novo after transplantation skin cancers are the most common, accounting for 95% of all skin neoplasms. Due to the significantly higher morbidity, aggressive, rapid progression of cancer and unfavorable prognosis, the population requires a specific oncological approach. Therefore, special attention should be paid to factors predisposing to the development of cancer, including skin cancer, in patients after organ transplantation. Some of these factors are well understood, while the role of others is still ambiguous. Among the etiological factors mentioned are those that are associated with the recipient. These include genetic factors such as male sex, fair skin and inability to be tanned, and compatibility of the HLA system, and non genetic factors such as patient age, chronic skin ulcers and scars, the type of transplanted organ, immunosuppression, and particularly the type and cumulative doses of drugs. In addition, the pathogenesis of cancer is influenced by environmental factors such as exposure to sunlight and therefore latitude, ionizing radiation, chemical carcinogens and viral infections. Knowledge of etiological factors and mechanisms of etiopathogenesis allow for indication and observation of patients with increased risk of cancer as well as faster healing in these patients.

We evaluated CMV prevalence in our islet transplant candidates (ITC) in comparison with organ donors. We correlated the CMV serological status of our ITC with serology for Epstein-Barr virus and Parvovirus B19, auto-antibodies, patient's age, age at DM onset, duration of DM, gender, race, ABO group, HLA haplotype and C-peptide levels. Cytomegalovirus transmission after islet transplant using the Edmonton regimen was also evaluated. Cytomegalovirus seropositivity varied according to patient group, age, gender and race. Type 1 DM patients had reduced odds of CMV seropositivity when compared with organ donors. In all groups studied, older patients, females, and non-Caucasians were more likely to be CMV seropositive. In addition, no CMV reactivation, infection or disease was observed among our transplanted patients using this steroid-free regimen even after donor/recipient CMV mismatch.

    Full Text Available Monica Bhatia,1 Sujit Sheth21Division of Pediatric Hematology/Oncology/Stem Cell Transplantation, Columbia University Medical Center, 2Division of Pediatric Hematology and Oncology, Weill Cornell Medical College, New York, NY, USAAbstract: Hematopoietic stem cell transplantation remains the only curative treatment currently in use for patients with sickle cell disease (SCD. The first successful hematopoietic stem cell transplantation was performed in 1984. To date, approximately 1,200 transplants have been reported. Given the high prevalence of this disorder in Africa, and its emergence in the developed world through immigration, this number is relatively small. There are many reasons for this; primary among them are the availability of a donor, the risks associated with this complex procedure, and the cost and availability of resources in the developing world. Of these, it is fair to say that the risks associated with the procedure have steadily decreased to the point where, if currently performed in a center with experience using a matched sibling donor, overall survival is close to 100% and event-free survival is over 90%. While there is little controversy around offering hematopoietic stem cell transplantation to symptomatic SCD patients with a matched sibling donor, there is much debate surrounding the use of this modality in “less severe” patients. An overview of the current state of our understanding of the pathology and treatment of SCD is important to show that our current strategy is not having the desired impact on survival of homozygous SCD patients, and should be changed to significantly impact the small proportion of these patients who have matched siblings and could be cured, especially those without overt clinical manifestations. Both patient families and providers must be made to understand the progressive nature of SCD, and should be encouraged to screen full siblings of patients with homozygous SCD for their potential to

    Full Text Available OBJECTIVE: To summarize the experience with salvage liver transplantation (SLT for patients with recurrent hepatocellular carcinoma (HCC after primary hepatic resection in a single center. METHODS: A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 2008. Among these patients, 36 underwent SLT after primary liver curative resection due to intrahepatic recurrence. During the same period, one hundred and forty-seven patients with HCC within Milan criteria underwent primary OLT (PLTW group, the intra-operative and post-operative parameters were compared between these two groups. Furthermore, we compared tumor recurrence and patient survival of patients with SLT to 156 patients with HCC beyond Milan criteria (PLTB group. Cox Hazard regression was made to identify the risk factors for tumor recurrence. RESULTS: The median interval between initial liver resection and SLT was 35 months (1-63 months. The intraoperative blood loss (P0.05. When compared to those patients with HCC beyond Milan criteria undergoing primary OLT, patients undergoing SLT achieved a better survival and a lower tumor recurrence. Cox Proportional Hazards model showed that vascular invasion, including macrovascular and microvascular invasion, as well as AFP level >400 IU/L were risk factors for tumor recurrence after LT. CONCLUSIONS: In comparison with primary OLT, although SLT is associated with increased operation difficulties, it provides a good option for patients with HCC recurrence after curative resection.

    Patient-identified barriers to immunosuppressive medications are associated with poor adherence and negative clinical outcomes in transplant patients. Assessment of adherence barriers is not part of routine post-transplant care, and studies regarding implementing such a process in a reliable way are lacking. Using the Model for Improvement and PDSA cycles, we implemented a system to identify adherence barriers, including patient-centered design of a barriers assessment tool, identification of eligible patients, clear roles for clinic staff, and creating a culture of non-judgmental discussion around adherence. We performed time-series analysis of our process measure. Secondary analyses examined the endorsement and concordance of adherence barriers between patient-caregiver dyads. After three methods of testing, the most reliable delivery system was an EHR-integrated tablet that alerted staff of patient eligibility for assessment. Barriers were endorsed by 35% of caregivers (n=85) and 43% of patients (n=60). The most frequently patient-endorsed barriers were forgetting, poor taste, and side effects. Caregivers endorsed forgetting and side effects. Concordance between patient-caregiver dyads was fair (k=0.299). Standardized adherence barriers assessment is feasible in the clinical care of pediatric kidney transplant patients. Features necessary for success included automation, redundant systems with designated staff to identify and mitigate failures, aligned reporting structures, and reliable measurement approaches. Future studies will examine whether barriers predict clinical outcomes (eg, organ rejection, graft loss). © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background Deceased donor kidneys are a scarce health resource, yet patient preferences for organ allocation are largely unknown. The aim of this study was to determine patient preferences for how kidneys should be allocated for transplantation. Methods Patients on dialysis and kidney transplant recipients were purposively selected from two centres in Australia to participate in nominal/focus groups in March 2011. Participants identified and ranked criteria they considered important for deceased donor kidney allocation. Transcripts were thematically analysed to identify reasons for their rankings. Results From six groups involving 37 participants, 23 criteria emerged. Most agreed that matching, wait-list time, medical urgency, likelihood of surviving surgery, age, comorbidities, duration of illness, quality of life, number of organs needed and impact on the recipient's life circumstances were important considerations. Underpinning their rankings were four main themes: enhancing life, medical priority, recipient valuation, and deservingness. These were predominantly expressed as achieving equity for all patients, or priority for specific sub-groups of potential recipients regarded as more "deserving". Conclusions Patients believed any wait-listed individual who would gain life expectancy and quality of life compared with dialysis should have access to transplantation. Equity of access to transplantation for all patients and justice for those who would look after their transplant were considered important. A utilitarian rationale based on maximizing health gains from the allocation of a scarce resource to avoid "wastage," were rarely expressed. Organ allocation organisations need to seek input from patients who can articulate preferences for allocation and advocate for equity and justice in organ allocation.

    Cystic fibrosis (CF) patients from Canada have better-reported post-lung transplant survival compared to patients from the United States. We hypothesized the clinical characteristics of CF patients prior to lung transplant differ between the two countries. Population-based cohort study utilizing combined Canadian CF Registry and US CF Foundation Patient Registry data from 1986 to 2013. Demographic and clinical variables were analyzed prior to lung transplant. Between 1986 and 2013, 607 (10.2%) CF patients underwent lung transplantation in Canada and 3428 (7.5%) in the United States. A lower proportion of recipients had growth of B. cepacia complex prior to transplant in the United States compared to Canada (0.8% vs 4.3%). Lung function was similar between recipients from the two countries. The proportion of patients classified as underweight was significantly higher in the United States compared to Canada (39.8% vs 28.0%; SD 26.1) despite higher rates of feeding tube use (42.5% vs 28.6%; SD 29.0). CF lung transplant recipients from the United States have similar lung function, lower rates of B. cepacia complex, and worse nutritional parameters prior to transplant compared to counterparts in Canada. Future studies are necessary to evaluate the impact of these differences on post-transplant survival. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Jacob A Tatum,* Max O Meneveau,* Kenneth L Brayman Department of Surgery, Division of Transplantation, The University of Virginia Health System, Charlottesville, VA, USA *These authors contributed equally to this work. Abstract: Type 1 diabetes mellitus is an autoimmune disorder of the endocrine pancreas that currently affects millions of people in the United States. Although the disease can be managed with exogenous insulin administration, the ultimate cure for the condition lies in restoring a patient’s ability to produce their own insulin. Islet cell allotransplantation provides a means of endogenous insulin production. Though far from perfected, islet transplants are now a proven treatment for type 1 diabetics. However, proper patient selection is critical for achieving optimal outcomes. Given the shortage of transplantable organs, selecting appropriate candidates for whom the procedure will be of greatest benefit is essential. Although many of those who receive islets do not retain insulin independence, grafts do play a significant role in preventing hypoglycemic episodes that can be quite detrimental to quality of life and potentially fatal. Additionally, islet transplant requires lifelong immunosuppression. Antibodies, both preformed and following islet infusion, may play important roles in graft outcomes. Finally, no procedure is without inherent risk and islet transfusions can have serious consequences for recipients’ livers in the form of both vascular and metabolic complications. Therefore, patient-specific factors that should be taken into account before islet transplantation include aims of therapy, sensitization, and potential increased risk for hepatic and portal-venous sequelae.

    2014-08-01

    Allogeneic hematopoietic stem cell transplantation (HSCT) offers a potential cure for a variety of diseases but is also associated with significant risks. With HSCT the donor is either a relative, most often a sibling, or an unrelated registry donor. The aim was to explore patients' experiences, immediately before transplantation, regarding having a sibling as donor. Ten adult patients with sibling donors were interviewed before admission for HSCT. The interviews were digitally recorded, transcribed verbatim and subjected to qualitative content analysis. The main theme Being in no man's land is a metaphor for the patients' complex situation with its mixture of emotions and thoughts prior to transplantation. The three subthemes Trust in the sibling donor, Concern about others and Loss of control cover the various experiences. The patient's experiences are influenced by their personal situation and the quality of the relationship with the sibling donor. While patients feel secure in having a sibling donor, they are dependent for their survival on the cell donation and feel responsible for the donor's safety during donation. These emotions intensify the patients' sense of dependency and loss of control. In caring for HSCT patients the nurses should be aware of the complexity of the patients' situation and keep in mind that having a sibling donor might imply extra pressure, including a sense of responsibility. Caring for both patients and sibling donors optimally is a challenge, which needs further improvement and exploration. Copyright © 2014 Elsevier Ltd. All rights reserved.

    To investigate the rate of metabolism of nitrogen-13 labelled ammonia ( 13 NH 3 ) in different conditions, we have determined the relative amount of unchanged 13 NH 3 in the blood of dogs, volunteers and transplant patients at different times following injection. In dogs, the determinations were made under basal conditions, during adenosine administration and after coronary occlusion. The results show that adenosine administration increases the metabolic rate whereas coronary occlusion does not affect 13 NH 3 metabolism. For both human volunteers and transplant patients the metabolic rate of 13 NH 3 was assessed under basal conditions and during adenosine administration. 13 NH 3 metabolism proceeds faster in transplant patients than in volunteers under both conditions. Adenosine administration causes a faster 13 NH 3 turnover in volunteers but not in transplant patients. Application of individual metabolite correction resulted in a 16% decrease in the calculated blood flow compared to uncorrected values. A smaller difference (5%) was observed between correction with mean metabolite values and individually acquired metabolite values. (orig.)

    Among solid organ transplant (SOT) recipients, donor-seropositive\\/recipient-seronegative (D+\\/R-) cytomegalovirus (CMV) status is associated with the highest risk of ganciclovir-resistant CMV disease, which has been reported for patients receiving oral ganciclovir but not valganciclovir prophylaxis. We report a case of CMV breakthrough infection in a D+\\/R- liver transplant patient while he was receiving oral valganciclovir. Forty samples collected over 6 months were analyzed for the CMV viral load, lymphocyte counts, cytokine levels, and lymphocyte differentiation status. Genotypic resistance testing of the viral UL97 gene was performed when the patient failed to respond. CMV viremia occurred on day 50 post-transplant, and 5 samples taken between days 50 and 85 showed the wild-type UL97 genotype. The appearance of deletion 594-595 was observed from day 114 post-transplant. Viral loads declined when foscarnet was commenced and remained below 10,000 copies\\/mL when the lymphocyte count was greater than 1000\\/microL (P = 0.02). T cell responses revealed significant expansion of CD8+ terminal effector memory cells. CD4+ cells were largely populations of naive and central memory cells. Circulating interleukin 10 (IL-10) levels correlated with the viral load (P < 0.0001). Seroconversion occurred on day 230. The CMV viral load in combination with lymphocyte counts and IL-10 may be a predictive marker for the risk of development of resistant CMV disease in D+\\/R- SOT patients.

    Full Text Available Abstract. Autologous hematopoietic stem cell transplantation (auto-HSCT is one of the most effective methods for treatment of patients with various forms of hemoblastoses, both in adults and children. However, high-dose chemotherapy protocols used in this procedure are characterized by pronounced myeloand immunotoxicity. Appropriate data concerning immune state at long terms after high-dose chemotherapy and auto-HSCT are sparse and controversial, and there is no consensus on time dynamics of immune system reconstitution. The aim of this study was a comprehensive evaluation of immunity in recipients of auto-HSCT at longer terms. Clinical and immunological testing was performed in ninety-eight patients with hematological malignancies before starting a high-dose chemotherapy, and at late post-transplant period. The state of cellular immunity was assessed as expression of surface CD3+, CD4+, CD8+, CD16+, CD19+ lymphocyte antigens. Humoral immunity was evaluated by serum IgG, IgA, and IgM levels. The studies have revealed disorders of cellular and humoral immunity, as well as nonspecific immune resistance factors in recipients of autologous hematopoietic stem cells at late terms post-transplant. Immune reconstitution in patients receiving highdose consolidation treatment followed by auto-HSCT takes longer time than in patients who did not receive autologous hematopoietic stem cells. Severity of these disturbances and immune reconstitution rates depend on the type of conditioning regimen, and the source of haematopoietic stem cells used for transplantation.

    We describe a case of progressive multifocal leucoencephalopathy (PML) in a 39-year-old patient diagnosed with chronic lymphocytic leukaemia (CLL) who underwent two allogenic matched-sibling stem cell transplantations. PML was confirmed just after the first transplantation with cerebral MRI and by PCR in the cerebrospinal fluid. After immunosuppression withdrawal and cidofovir treatment, he achieved a reversal of clinical symptoms, John Cunningham (JC) virus positivity and MRI lesions regression. He remained asymptomatic for 5 years with no signs of infection activity, even though he received three new chemotherapy regimens due to a CLL relapse. However, after the second stem cell transplantation, new neurological symptoms began and a reactivation of the JC virus infection was detected. This time, treatment with mefloquine was started, but he experienced a progressive neurological deterioration and died 1 month after the symptoms began.

    Adherence to immunosuppressants (IS) is crucial to prevent allograft rejection. Even though there is evidence that non-adherence to IS among kidney transplant recipients is common, it is rarely routinely assessed in clinical practice. Especially, little is known about how physicians estimate patients' adherence to IS medication. In a single center, cross-sectional study adult patients at least 1 year after kidney transplantation were asked to complete measures of adherence (BAASIS©, Transplant Effect Questionnaire) and of general psychopathology (anxiety, depression, perceived social support). Also the physicians were asked to estimate their patients' adherence. Medical data (time since transplantation, treatment for rejection, IS serum trough levels and target levels) were taken from the patients' charts. Physicians rated 22 of 238 (9.2%) patients as non-adherent. Physicians' estimations of non-adherence were lower compared to the results of the self-ratings and biopsy-proven rejections. No association was found between physicians' estimates and the variability of IS through levels. Significantly more women and patients who reported that their native language was not German were rated as non-adherent by the physicians. Also, physician-rated non-adherent patients reported significantly higher depression and anxiety scores as well as less social support compared to adherent patients. Our results suggest that physicians tend to underestimate patient non-adherence to IS medication. They appear to use observable cues such as sex, language skills, and elevated anxiety and depression scores in particular, to make inferences about an individual patient's adherence. Underestimation of medication non-adherence may impede physicians' ability to provide high quality care. Copyright © 2015 Elsevier Inc. All rights reserved.

    In solid organ transplant patients, non-participation in all aspects of the medical regimen is a prevalent problem associated with adverse consequences particularly in the adolescent and young adult (AYA) age group. This study is the first to evaluate the feasibility, utility and impact of a text messaging (TM) intervention to improve participation in laboratory testing in adolescent liver transplant patients. AYA patients, aged 12 to 21 years, were recruited for a prospective pilot trial evaluating a TM intervention delivered over a 1-year period. The intervention involved automated TM reminders with feedback administered according to a prescribed laboratory testing frequency. Participation rate in laboratory testing after the intervention was compared to the year prior. Patient responses and feedback by text and survey were used to assess feasibility, acceptability and use of the intervention. Forty-two patients were recruited and 33 patients remained enrolled for the study duration. Recipients of the TM intervention demonstrated a significant improvement in participation rate in laboratory testing from 58% to 78% (Prate was also significantly higher than in non-intervention controls (P=.003). There was a high acceptability, response rate and a significant correlation with reported versus actual completion of laboratory tests by TM. TM reminders significantly improved participation in laboratory testing in AYA liver transplant patients. The intervention demonstrated feasibility, acceptability, and use with a high proportion of patients who engaged in and perceived a benefit from using this technology.

    Full Text Available Acute sickle hepatic crisis (ASHC has been observed in approximately 10% of patients with sickle cell disease. It occurs predominantly in patients with homozygous (Hb SS sickle cell anemia and to a lesser degree in patients with Hb SC disease, sickle cell trait, and Hb S beta thalassemia. Patients commonly present with jaundice, right upper quadrant pain, nausea, low-grade fever, tender hepatomegaly, and mild to moderate elevations in serum AST, ALT, and bilirubin. We describe the case of a patient with a history of hemoglobin SC disease and cirrhosis caused by hepatitis C presenting approximately 1 year after liver transplantation with an ASHC. The diagnosis was confirmed by liver biopsy. Our patient was treated with RBC exchange transfusions, IV hydration, and analgesia and made a complete recovery. Only a limited number of patients with sickle cell disease have received liver transplants, and, to our knowledge, this is the first case of ASHC after transplantation in a patient with Hb SC disease.

    Cartilage-hair hypoplasia (CHH) is a rare autosomal recessive disease caused by mutations in the RMRP gene. Beside dwarfism, CHH has a wide spectrum of clinical manifestations including variable grades of combined immunodeficiency, autoimmune complications, and malignancies. Previous reports in single CHH patients with significant immunodeficiencies have demonstrated that allogeneic hematopoietic stem cell transplantation (HSCT) is an effective treatment for the severe immunodeficiency, while growth failure remains unaffected. Because long-term experience in larger cohorts of CHH patients after HSCT is currently unreported, we performed a European collaborative survey reporting on 16 patients with CHH and immunodeficiency who underwent HSCT. Immune dysregulation, lymphoid malignancy, and autoimmunity were important features in this cohort. Thirteen patients were transplanted in early childhood ( approximately 2.5 years). The other 3 patients were transplanted at adolescent age. Of 16 patients, 10 (62.5%) were long-term survivors, with a median follow-up of 7 years. T-lymphocyte numbers and function have normalized, and autoimmunity has resolved in all survivors. HSCT should be considered in CHH patients with severe immunodeficiency/autoimmunity, before the development of severe infections, major organ damage, or malignancy might jeopardize the outcome of HSCT and the quality of life in these patients.

    To review the outcome following simultaneous pancreas and kidney transplantation in patients with type 1 diabetes mellitus and end-stage renal disease, as well as those with type 2 diabetes mellitus, and to discuss the applicability of this treatment in this locality. A systematic literature review was performed by searching the PubMed and Elsevier databases. The search terms used were "simultaneous pancreas and kidney transplantation", "diabetes", "pancreas transplant" and "SPK". Original and major review articles related to simultaneous pancreas and kidney transplantation were reviewed. Papers published in English after 1985 were included. Clinical outcomes following transplantation were extracted for comparison between different treatment methods. Outcomes of simultaneous pancreas and kidney transplant and other transplantation methods were identified and categorised into patient survival, graft survival, diabetic complications, and quality of life. Patient survivals and graft survivals were also compared. Currently available clinical evidence shows good outcomes for type 1 diabetes mellitus in terms of patient survival, graft survival, diabetic complications, and quality of life. For type 2 diabetes mellitus, the efficacy and application of the procedure remain controversial but the outcomes are possibly comparable with those in type 1 diabetes mellitus. Simultaneous pancreas and kidney transplantation is a technically demanding procedure that is associated with significant complications, and it should be regarded as a 'last resort' treatment in patients whose diabetic complications have become life-threatening or severely burdensome despite best efforts in maintaining good diabetic control through lifestyle modifications and medications.

  20. Body composition of Fanconi anemia patients after hematopoietic stem cell transplantation

    Priscilla Peixoto Policarpo da Silva

    Full Text Available Abstract Introduction: Fanconi anemia is a rare genetic disease linked to bone marrow failure; a possible treatment is hematopoietic stem cell transplantation. Changes in the nutritional status of Fanconi anemia patients are not very well known. This study aimed to characterize body composition of adult, children and adolescent patients with Fanconi anemia who were submitted to hematopoietic stem cell transplantation or not. Methods: This cross-sectional study enrolled 63 patients (29 adults and 34 children and adolescents. Body composition was assessed based on diverse methods, including triceps skin fold, arm circumference, arm muscle area and bioelectrical impedance analysis, as there is no established consensus for this population. Body mass index was also considered as reference according to age. Results: Almost half (48.3% of the transplanted adult patients were underweight considering body mass index whereas eutrophic status was observed in 66.7% of the children and adolescents submitted to hematopoietic stem cell transplantation and in 80% of those who were not. At least 50% of all groups displayed muscle mass depletion. Half of the transplanted children and adolescents presented short/very short stature for age. Conclusion: All patients presented low muscle stores, underweight was common in adults, and short stature was common in children and adolescents. More studies are needed to detect whether muscle mass loss measured at the early stages of treatment results in higher risk of mortality, considering the importance of muscle mass as an essential body component to prevent mortality related to infectious and non-infectious diseases and the malnutrition inherent to Fanconi anemia.

    Congenital atresia of the common and external iliac arteries is a rare vascular anomaly that may be associated with congenital renal or genitourinary malformations. In ESRD patients, its presence may pose potential problems during renal transplantation. We report a rare case of kidney transplantation in a patient with VACTERL syndrome who was found to have absent right common and external iliac arteries during pre-operative imaging. Vascular supply to the right lower limb is derived from an anomalous branch from the left internal iliac artery which takes on a convoluted course across the pelvis. Kidney transplantation was performed successfully with implantation performed on the left side. Isolated cases of congenital iliac artery atresia have been described in association with urological abnormalities but no clear association has yet been established. However, we feel that it may be useful to perform routine angiographic evaluation for ESRD patients with congenital genitourinary abnormalities being planned for kidney transplantation. While most cases of congenital iliac artery anomalies are symptomatic with claudication, some remain asymptomatic with normal physical examination findings. There is some evidence in literature suggesting the usefulness of routine pre-operative CT in a selective group of patients. Kidney transplantation in such cases is safe and we recommend routine pre-operative imaging of patients known to have congenital genitourniary abnormalities. The kidney should be implanted heterotopically to the contralateral side of the vascular anomaly and care must be taken to preserve vascular supply to the lower limbs. Copyright © 2015 The Authors.

    To deride the hope of progress is the ultimate fatuity, the last word in poverty of spirit and meanness of mind. There is no need to be dismayed by the fact that we cannot yet envisage a definitive solution of our problems, a resting-place beyond which we need not try to go. -P.B. Medawar, 1969 * Thomas E. Starlz, also known as the Father of Clinical Transplantation, once said that organ transplantation was the supreme exception to the rule that most major advances in medicine spring from discoveries in basic science [Starzl T. The mystique of organ transplantation. J Am Coll Surg 2005 Aug;201(2):160-170]. In fact, the first successful identical-twin kidney transplantation performed by Murray's team in December 1954 (Murray J et al. Renal homotransplantations in identical twins. Surg Forum 1955;6:432-436) was the example of an upside down translation medicine: Human clinical transplantation began and researchers tried to understand the underlying immune response and how to control the powerful rejection pathways through experimental models. In the last 20 years, we have witnessed an amazing progress in the knowledge of immunological mechanisms regarding alloimmune response and an outstanding evolution on the identification and characterization of major and minor histocompatibility antigens. This review presents an historical and clinical perspective of those important advances in kidney transplantation immunology in the last 20 years, which contributed to the improvement in patients' quality of life and the survival of end-stage renal patients. In spite of these significant progresses, some areas still need substantial progress, such as the definition of non-invasive biomarkers for acute rejection; the continuous reduction of immunosuppression; the extension of graft survival, and finally the achievement of real graft tolerance extended to HLA mismatch donor: recipient pairs.

    2016-12-01

    Full Text Available Background: Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT recipients. Objective: This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20 might have lower medication adherence than noncomplex patients (INTERMED≤20. Methods: Each patient eligible for transplantation at the University Hospital of Lausanne, Switzerland, has to undergo a pre-transplantation psychiatric evaluation. In this context the patient was asked to participate in our study. The INTERMED was completed pre-transplantation, and adherence to immunosuppressive medication was monitored post-transplantation by electronic monitors for 12 months. The main outcome measure was the implementation and persistence to two calcineurin inhibitors, cyclosporine and tacrolimus, according to the dichotomized INTERMED score (>20 or ≤20. Results: Among the 50 SOT recipients who completed the INTERMED, 32 entered the study. The complex (N=11 and noncomplex patients (N=21 were similar in terms of age, sex and transplanted organ. Implementation was 94.2% in noncomplex patients versus 87.8% in complex patients (non-significant p-value. Five patients were lost to follow-up: one was non-persistent, and four refused electronic monitoring. Of the four patients who refused monitoring, two were complex and withdrew early, and two were noncomplex and withdrew later in the study. Conclusion: Patients identified as complex pre-transplant by the INTERMED tended to deviate from their immunosuppressant regimen, but the findings were not statistically significant. Larger studies are needed to evaluate this association further, as well as the appropriateness of using a nonspecific biopsychosocial instrument such as INTERMED in highly

    Pre-existing occlusion of the inferior vena cava may complicate renal transplantation. Suppurative abdominal wall phlebitis following renal transplantation was diagnosed in a patient with pre-existing thrombosis of the inferior vena cava of unknown cause. The phlebitis developed in the subcutaneous collateral veins of the abdominal wall contra-laterally to the renal transplant. Cultures from abdominal wall micro-abscesses yielded Prevotella bivia as the causative agent. This complication has not been described before in the context of renal transplantation. The pathogenesis and management of this serious complication are discussed in this paper.

    Full Text Available Immunosuppressive treatment increases the risk of infection and malignancy in organ transplant recipients. We report on a 42-year-old male renal transplant recipient who lost his first graft after reduction of immunosuppressive treatment due to Kaposi sarcoma and who successfully underwent a second renal transplant 10 years later. The patient’s current treatment consists of low-dose prednisone, and the two antiproliferative immunosuppressants mycophenolate mofetil and rapamycin. 4.5 years after his second transplant, the serum creatinine is 1 mg/dl and the patient has no signs of recurrent disease.

    We hypothesized the levels of free light chains obtained before and after autologous stem cell transplantation can be useful in predicting transplantation outcome. We analyzed 70 multiple myeloma patients. Abnormal free light chain ratios before stem cell transplantation were found to be associated early progression, although without any impact on overall survival. At day +30, the normalization of levels of involved free light chain related with early progression. According to these results almost one-third reduction of free light chain levels can predict favorable prognosis after autologous stem cell transplantation.

    Full Text Available AimThis paper aimed to analyze the coping strategies adopted by patients in preparation to kidney transplant, as well as associations between coping and socio-demographic data.MethodA total of 76 patients took part in this descriptive, exploratory study. While waiting for the first medical consultation regarding kidney transplantation, participants answered the Brazilian version of the Ways of Coping Scale.ResultsThe main coping strategies adopted corresponded first to religiosity, then problem focused coping and seeking for social support. There were statistically significant associations between coping categories and gender, marital status, monthly income, children’s ages, and time in dialysis.ConclusionThis study highlights the main coping strategies adopted by patients in preparation to kidney transplant, and it also reveals associations between some socio-demographic data and coping. These results may promote further psychosocial interventions, which may help to improve preparation to kidney transplants, promoting better adaptation and treatment adherence as well as fewer psychological burdens.

    Full Text Available The goal of this study was to evaluate the attitude of the physicians towards the follow-up of the renal transplant patients in the Kingdom of Saudi Arabia (KSA. We sent a questionnaire to 168 physicians working in 148 active dialysis centers in the KSA. The study was conducted from June-October 2005. There were 140 physicians (83.3% who answered the questionnaire; they represented 136 (91.9% dialysis centers. There were 43 (31.2% respondents who had a transplant clinic for follow-up of transplant recipients. Of the 96 (69.1% who did not have a clinic, 29 (30.2% claimed expertise for follow-up of transplant recipients, six (6.2% had a laboratory set-up to monitor the immunosuppressive drug levels and 40 (44.4% felt the need for one.

    Full Text Available The objective of this study was to investigate the occurrence of vancomycin-resistant Enterococcus (VRE cross-transmission between two patient groups (long-term dialysis and kidney transplant patients. Molecular typing, by automated ribotyping with the RiboPrinter Microbial Characterization System (Qualicon, USA, was used to analyze VRE isolates from 31 fecal samples of 320 dialysis patients and 38 fecal samples of 280 kidney transplant patients. Clonal spread of E. faecalis and E. casseliflavus was observed intragroup, but not between the two groups of patients. In turn, transmission of E. gallinarum and E. faecium between the groups was suggested by the finding of vancomycin-resistant isolates belonging to the same ribogroup in both dialysis and transplant patients. The fact that these patients were colonized by VRE from the same ribogroup in the same health care facility provides evidence for cross-transmission and supports the adoption of stringent infection control measures to prevent dissemination of these bacteria.

    Objective: To study the clinical significance of post-operative changes of serum IL-18 levels in patients after renal transplantation. Methods: Serum IL-18 levels were detected with ELISA in 33 patients with renal transplantation before operation and repeated again on d5, d10 and d20 post-operatively as well as in 35 controls. Results: Pre-operatively, serum IL-18 levels in patients for upcoming renal transplantation were significantly higher than those in controls (P<0.01). After operation, the IL-18 levels on d5 and d10 in patients with acute rejection were not significantly changed from those pre-operatively but were markedly increased on d20 (vs pre-operative, d5, d10; all P<0.01). In the patients without rejection, levels in d5 were significantly higher than those pre-operatively, but dropped to approaching pre-operative values on d10 and d20. On d20, levels of serum IL-18 in patients with rejection were very significantly higher than those in stable patients (P<0.01). Conclusion: Serum IL-18 is a useful marker for identifying acute rejection. (authors)

    Glomerular filtration rate (GFR) is partially impaired in patients with multiple sclerosis (MS). When given chemotherapy before receiving hematopoietic stem-cell transplantation, GFR might be further deteriorated. To measure the effect of cyclophosphamide on GFR in patients with MS who undergo chemotherapy. We estimated GFR based on creatinine and cystatin C plasma concentrations in patients undergoing autologous hematopoietic stem-cell transplantation to treat their MS. Baseline GFR values were lower in the 28 patients with MS than in the 20 healthy individuals. Also, according to the Chronic Kidney Disease-Epidemiology Collaborative Group (CKD-EPI) 2012 Creat-CysC equation criteria, 4 of 28 patients were classified as having chronic kidney disease (CKD) before receiving the chemotherapy drugs. After receiving 4 × 50 mg per kg body weight cyclophosphamide, abnormal GFR results were recorded in 12 of 28 patients. Renal function must be monitored in patients with MS undergoing autologous stem-cell transplantation. Also, chemotherapy should be constrained as much as possible to prevent further deterioration of renal function.

    The results of the bacteriological surveillance cultures for 26 patients with bone marrow transplantation (Karl Marx University Leipzig, G.D.R., 1985-1987) are presented. 5.9% of all surveillance cultures contained facultatively pathogenic germs (with Pseudomonas aeruginosa as the most frequent representative, which was the reason of a sepsis in two patients). Coagulasenegative Staphylococci and other germs with an obscure pathogenicity were isolated upon a large scale, especially from the mucous membrane regions. There are hints, that above all special strains of coagulasenegative Staphylococci "colonize" the patient's body (also for longer periods) and turn into the blood too. During the total decontamination intestinal anaerobic flora is absent. After closing of total decontamination Clostridium perfringens is the first detectable anaerobic species. During the selective decontamination systemic applications of antibiotics are able to obliterate anaerobic findings for certain periods. Recommendations for an effective arrangement of the surveillance cultures of bone marrow transplantation patients are given.

    Full Text Available Context Liver transplantation has been accepted as a therapeutic option for patients with end-stage liver disease and acute liver failure. Currently, Brazil has a well-established public organ transplant program, performing 7,425 solid organs transplants in 2012 alone, among which 1,595 were liver transplants. Jehovah's Witnesses report 7,6 million members worldwide. For religious reasons they refuse transfusion of whole blood or its primary components (red cells, fresh frozen plasma, platelets. Objective This study aims to present the results obtained with Jehovah's Witnesses patients by a liver transplantation service. Method We conducted a retrospective review of medical records from Jehovah's Witnesses patients (n = 4 who underwent orthotopic liver transplantation from September 2009 to September 2011 at the Walter Cantídio University Hospital of the Federal University of Ceará, Fortaleza, CE, Brazil. Coagulation parameters such as Hemoglobin, Hematocrit, Platelets, INR were evaluated during the preoperative, immediate postoperative, postoperative day (POD 7 and POD 30. Results Coagulation parameters were expressed as means: hematocrit, 35.07% ± 6.65%, 24.6% ± 4.74%, 19.85% ± 2.10%, 31.85% ± 5.99%; hemoglobin, 12.57 g/dL ± 2.22, 8.92 g/dL ± 1.75, 6.92 g/dL ± 0.58, 11.17 g/dL ± 0.9; platelets, 160,975 mm 3 ± 148000, 128,000 mm 3 ± 34836, 65,000 mm 3 ± 33496, 234,250 mm 3 ± 287003 and INR, 143 ± 0.10, 2.4 ± 0.34, 1.24 ± 0.10, 1.14 ± 0.09. Conclusion Liver transplantation can successfully be performed in Jehovah's Witnesses patient population provided that: 1 the medical team has extensive expertise in that field, 2 the patient has an adequate level of hematologic factors preoperatively, and 3 there is availability of specialized equipment such as cell saver to minimize blood loss and thus avoid transfusion requirements.

    Uncorrected hypernatremia in organ donors has been associated with poor graft or patient survival during liver transplants. However, recent studies have found no association between the donor serum sodium and transplant outcome. This study sought to show the negative effect donor hypernatremia has on initial liver allograft function. This is the first study to investigate international normalized ratio and renal factors of patients with normal and those with hypernatremic donor livers. This study was conducted at the Shiraz Transplant Research Center in Shiraz, Iran, between May 2009, and July 2011. Four hundred seven consecutive adult orthotopic liver transplants were performed at the University of Shiraz Medical Center. There were 93 donors in the group with hypernatremia with terminal serum sodium of 155 mEq/L or greater (group 1), and 314 with terminal serum sodium less than 155 mEq/L (group 2). Posttransplant data after 5 days showed that aspartate aminotransferase, alanine aminotransferase, international normalized ratio, and kidney function did not differ between the groups. Hypernatremia is the most important complication after brain death. Previous studies have suggested donor hypernatremia results in a greater incidence of early postoperative graft dysfunction in liver transplant and is considered one of the extended criteria donor. However, in recent years, this hypothesis has been questioned. Our study shows no difference between patients' initial results of liver and kidney functioning with normal and hypernatremic donor livers. This is the first study to investigate international normalized ratio as a fundamental factor in defining early allograft dysfunction and renal factors between patients with normal and hypernatremic donor's livers.

    Haematopoietic stem cell transplant is a potentially curative treatment option in various benign and malignant haematological diseases. Patients undergoing stem cell transplant procedure require blood transfusion on a daily basis. Currently, there is paucity of data from developing countries on transfusion practices. This audit was undertaken to determine the consumption of packed red blood cells (PRBCs) transfusion in the bone marrow transplant unit of the Aga Khan University Hospital. A retrospective audit was conducted for packed red cell transfusion ordering practice over a period from June 2014∼June 2015. All consecutive patients, admitted for stem cell transplant procedure for various underlying diseases were included. Outcome measures used in this study were (i) cross match to transfusion (C: T) ratio and (ii) transfusion trigger. During the study period, n=25 patients underwent haematopoietic stem cell transplant. There were n=19 males and n=6 females. One patient was less than 15 years of age while rests were adults. Median age±SD was 26.5±14.5 years (12∼54 years). The underlying diagnosis included Aplastic anemia (n=8), Thalassemia major (n=3), Multiple Myeloma (n=4), Acute leukemia (n=5), Hodgkin's lymphoma (n=4), PRCA (n=1). Grand total consumption of PRBCs during the study period was 204 while 258 products were crossmatch. The C:T ratio was 1.26. The transfusion trigger was Hb level of less than 8 gms/dl. The results of our BMT unit indicate that the C:T ratio and transfusion trigger is comparable to the international benchmark.

    Liver transplantation-associated acute kidney injury (AKI) carries significant morbidity and mortality. We hypothesized that sodium bicarbonate would reduce the incidence and/or severity of liver transplantation-associated AKI. In this double-blinded pilot RCT, adult patients undergoing orthotopic liver transplantation were randomized to an infusion of either 8.4% sodium bicarbonate (0.5 mEq/kg/h for the first hour; 0.15 mEq/kg/h until completion of surgery); (n = 30) or 0.9% sodium chloride (n = 30). AKI within the first 48 h post-operatively. There were no significant differences between the two treatment groups with regard to baseline characteristics, model for end-stage liver disease and acute physiology and chronic health evaluation (APACHE) II scores, and pre-transplantation renal function. Intra-operative factors were similar for duration of surgery, blood product requirements, crystalloid and colloid volumes infused and requirements for vasoactive therapy. Eleven patients (37%) in the bicarbonate group and 10 patients (33%) in the sodium chloride group developed a post-operative AKI (p = 0.79). Bicarbonate infusion attenuated the degree of immediate post-operative metabolic acidosis; however, this effect dissipated by 48 h. There were no significant differences in ventilation hours, ICU or hospital length of stay, or mortality. The intra-operative infusion of sodium bicarbonate did not decrease the incidence of AKI in patients following orthotopic liver transplantation. © 2016 John Wiley & Sons A/S.

    BACKGROUND.: Although donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA) have been implicated in graft rejection in solid organ transplantation, their role in hematopoietic stem-cell transplantation remains unclear. METHODS.: To address the hypothesis that the presence of DSA contributes to the development graft failure, we tested 24 consecutive patients for the presence of anti-HLA antibodies determined by a sensitive and specific solid-phase/single-antigen assay. The study included a total of 28 haploidentical transplants, each with 2 to 5 HLA allele mismatches, at a single institution, from September 2005 to August 2008. RESULTS.: DSA were detected in five patients (21%). Three of four (75%) patients with DSA before the first transplant failed to engraft, compared with 1 of 20 (5%) without DSA (P=0.008). All four patients who experienced primary graft failure had second haploidentical transplants. One patient developed a second graft failure with persistent high DSA levels, whereas three engrafted, two of them in the absence of DSA. No other known factors that could negatively influence engraftment were associated with the development of graft failure in these patients. CONCLUSIONS.: These results suggest that donor-specific anti-HLA antibodies are associated with a high rate of graft rejection in patients undergoing haploidentical stem-cell transplantation. Anti-HLA sensitization should be evaluated routinely in hematopoietic stem-cell transplantation with HLA mismatched donors.

    The liver transplant patient was admitted to the hospital with hyperemic, granulomatous, ulcerated lesion in the anterior compartment of the right lower limb with report of local trauma. The agent Sporothrix schenckii was isolated from biopsy of the lesion and lymph nodes of the right lower limb. In this case, the treatment was difficult because the patient has severe pulmonary hypertension and took the following drugs: warfarin, sildenafil, and tacrolimus. These medicines interact with the antifungal, which made it difficult.

    Pseudomembranous aspergillus bronchitis is considered as an early form of invasive pulmonary aspergillosis, a well-known airway infection in immunocompromised patients. Radiologic features concerning invasive aspergillosis of the airways have been reported. However, we describe here an unusual feature of invasive aspergillus bronchitis, never reported to date, observed in a double-lung transplanted patient. Chest radiograph and CT revealed significant peribronchial thickening without any parenchymal involvement. (orig.)

    To describe and analyze the pharmaceutical orientation given at hospital discharge of transplant patients. This was a cross-sectional, descriptive and retrospective study that used records of orientation given by the clinical pharmacist in the inpatients unit of the Kidney and Liver Transplant Department, at Hospital Universitário Walter Cantídio, in the city of Fortaleza (CE), Brazil, from January to July, 2014. The following variables recorded at the Clinical Pharmacy Database were analyzed according to their significance and clinical outcomes: pharmaceutical orientation at hospital discharge, drug-related problems and negative outcomes associated with medication, and pharmaceutical interventions performed. The first post-transplant hospital discharge involved the entire multidisciplinary team and the pharmacist was responsible for orienting about drug therapy. The mean hospital discharges/month with pharmaceutical orientation during the study period was 10.6±1.3, totaling 74 orientations. The prescribed drug therapy had a mean of 9.1±2.7 medications per patient. Fifty-nine drug-related problems were identified, in which 67.8% were related to non-prescription of medication needed, resulting in 89.8% of risk of negative outcomes associated with medications due to untreated health problems. The request for inclusion of drugs (66.1%) was the main intervention, and 49.2% of the medications had some action in the digestive tract or metabolism. All interventions were classified as appropriate, and 86.4% of them we able to prevent negative outcomes. Upon discharge of a transplanted patient, the orientation given by the clinical pharmacist together with the multidisciplinary team is important to avoid negative outcomes associated with drug therapy, assuring medication reconciliation and patient safety.

    Mobile phone based remote monitoring of medication adherence and physiological parameters has the potential of improving long-term graft outcomes in the recipients of kidney transplants. This technology is promising as it is relatively inexpensive, can include intuitive software and may offer the ability to conduct close patient monitoring in a non-intrusive manner. This includes the optimal management of comorbidities such as hypertension and diabetes. There is, however, a lack of data assessing the attitudes of renal transplant recipients toward this technology, especially among ethnic minorities. To assess the attitudes of renal transplant recipients toward mobile phone based remote monitoring and management of their medical regimen; and to identify demographic or clinical characteristics that impact on this attitude. After a 10 minute demonstration of a prototype mobile phone based monitoring system, a 10 item questionnaire regarding attitude toward remote monitoring and the technology was administered to the participants, along with the 10 item Perceived Stress Scale and the 7 item Morisky Medication Adherence Scale. Between February and April 2012, a total of 99 renal transplant recipients were identified and agreed to participate in the survey. The results of the survey indicate that while 90% (87/97) of respondents own a mobile phone, only 7% (7/98) had any prior knowledge of mobile phone based remote monitoring. Despite this, the majority of respondents, 79% (78/99), reported a positive attitude toward the use of a prototype system if it came at no cost to themselves. Blacks were more likely than whites to own smartphones (43.1%, 28/65 vs 20.6%, 7/34; P=.03) and held a more positive attitude toward free use of the prototype system than whites (4.25±0.88 vs 3.76±1.07; P=.02). The data demonstrates that kidney transplant recipients have a positive overall attitude toward mobile phone based health technology (mHealth). Additionally, the data demonstrates

    Early detection of alcohol misuse in orthotopic liver transplantation recipients is essential to offer patients support and prevent organ damage. Here, ethyl glucuronide, a metabolite of ethanol found in hair (hEtG), was evaluated for detection of alcohol consumption. In 104 transplant recipients, 31 with underlying alcoholic liver disease (ALD) and 73 with non-ALD, hEtG was determined in addition to the alcohol markers urine EtG, blood ethanol, methanol, and carbohydrate-deficient transferrin. Results were compared with patients' self-reports in a questionnaire and with physicians' assessments. By physicians' assessments, 22% of the patients were suspected of consuming alcohol regularly, although only 6% of the patients acknowledged consumption of a moderate or high amount of alcohol. By testing all markers except for hEtG, alcohol consumption was detected in 7% of the patients. When hEtG testing was added to the assessment, consumption was detected in 17% of the patients. Hair-EtG determination alone revealed chronic alcohol consumption of >10 g/d in 15% of the patients. ALD patients had a positive hEtG result significantly more often than non-ALD patients did (32% versus 8%; P = 0.003). Also, the concentration of hEtG was higher in ALD patients (P = 0.049) and revealed alcohol abuse with consumption of >60 g ethanol per day in 23% of ALD and 3% of non-ALD patients. Patients' self-reports and physicians' assessments had a low sensitivity of 27% and 67%, respectively, for detecting regular alcohol intake as indicated by hEtG. Hair-EtG determination improved the detection of liver transplant patients who used alcohol, and revealed regular alcohol consumption in 32% of ALD and 8% of non-ALD patients.

    Between November 1985 and November 1989, 54 patients have undergone 55 cardiac transplants, 5 of whom died during operation or one week after transplantation. The remaining 49 patients with a minimum follow-up of 5 months were studied to examine pulmonary infection clinically and radiologically while receiving triple drug immunosuppression consisting of cyclosporine, azathioprine, and prednisolone. Pulmonary infection occurred in 14 patients (29%) with a total of 21 occasions. Causative organisms were identified in 9 occasions, with the most common organism being Cytomegalovirus (CMV). One patient died of pulmonary infection with Aspergillus. Causative organisms occurring in the remaining 12 occasions of pulmonary infection were unknown, which did not lead to death. Because pulmonary infection of unknown organisms rapidly responded to convensional antibiotics, it seemed to have been caused by bacteria. Pulmonary infection of unknown organism occurred 13.2{+-}3.2 months after transplantation, as compared with 3.3{+-}1.0 months in pulmonary infection of known organisms. Chest plain radiographic features fell into four types: (1) interstitial shadow seen in pulmonary infection of CMV, Pneumocystis carinii, or Hemophilia influenza, (2) patchy, and basilar and lobular consolidation shadows in bacterial pneumonia, (3) localized nodular shadow in aspergillosis, and (4) multiple patchy and confluent opacity patterns occurring in herpes simplex viral infection. Pulmonary infection of influenza bacteria for one patient and pulmonary infection of unknown organisms for 4 patients were difficult to identify from pulmonary infection of CMV. (N.K.).

    This study's purpose was to investigate the attitudes toward organ donation among renal transplantation patients and their caregivers. In addition, we sought to explore the impact factors that affect their attitudes toward deceased organ donation. A self-administrated questionnaire was used, which consisted of two parts: 1) demographic data, and 2) transplantation and donation-related data. This study was conducted in three transplantation follow-up centers in three hospitals using a cross-sectional approach. SPSS 17.0 software was used to analysis descriptive and inferential statistics for data. The responses were analyzed using descriptive statistics and logistic regression analysis. We received 426 effective questionnaires. The renal transplantation patients' mean age was 40.84 years. Among these patients, 67.8% were willing to accept the organ transplantation surgery for their relatives, 67.4% were willing to donate a living kidney to a close relative, 62.7% were willing to donate organs after death, 53.5% were willing to register in the national organ donation system, and 51.4% were willing to sign the organ donation consent when facing their relatives becoming a potential organ donor. Age, marriage status, education level, understanding of transplantation procedures and understanding of donation procedures had statistical significance in the difference of the attitudes toward donate their organs after death (P donate organs after death than their caregivers, but both their attitudes toward deceased donation were not very optimistic. There is a significant relationship between participants' willingness and knowledge of organ donation; patients with more understanding of the transplantation and donation procedure were more willing to donate organs after death. Affected by traditional values such as Confucianism, many people still cannot accept registering in the national organ donation system or sign the organ donation consent when facing their relatives

    2017-02-01

    Full Text Available Background: Patients with common variable immunodeficiency show higher incidence of sinopulmonary and gastrointestinal infections, as well as lymphoproliferative and autoimmune diseases. The treatment of choice is replacement therapy with human gamma-globulin. Hematopoietic stem cell transplantation is a non-conventional therapeutic modality. Clinical case: Twenty-six-year old woman with no family or hereditary history of primary immune deficiencies or consanguinity, with repeated episodes of otitis, sinusitis, gastroenteritis and bronchitis since childhood. At adolescence, she was diagnosed with common variable immunodeficiency; she was prescribed intravenous gamma-globulin, broad-spectrum antimicrobials and macrolides. At 22 years of age, she underwent hematopoietic stem cell transplantation owing to continued severe infections. At 4 months, post-transplantation she was diagnosed with hypothyroidism and ovarian insufficiency. During the following 3 years, she had no infections, but at 25 years of age she had immune thrombocytopenic purpura diagnosed, which persists together with Raynaud’s disease and upper respiratory tract persistent infections. At the moment of this report she is being treated with intravenous gamma-globulin and receiving prophylaxis with clarithromycin, without steroids or danazol. Conclusions: Given the high rate of morbidity and mortality associated and immune reconstitution failure, hematopoietic stem cell transplantation should be carefully evaluated in patients with treatment-unresponsive infections or lymphoproliferative disorders.

    Literature review suggests that adherence to immunosuppressive drugs may be lower in recipients of living than of deceased donor kidney grafts, possibly because of profile differences. To compare the level of immunosuppressive adherence levels between patients with deceased and living (-related; -unrelated) donor grafts in Switzerland. Using data from two similar cross-sectional studies at two transplant centers in Switzerland, the level of adherence between the two groups was compared. Medication adherence was assessed by self-report or electronic monitoring. Possible explanatory factors included age, beliefs regarding immunosuppressive drugs, depressive symptomatology, pre-emptive transplantation, and the number of transplants received, were also considered. Data were analyzed using logistic regression analysis. Unadjusted non-adherence odds were 2 to 3 times higher in living-related than deceased donor transplantation (ORs: 2.09-3.05; padherence in recipients of living-related donor kidneys, possibly owing to differences in patient profile (ie, health beliefs regarding their immunosuppressive needs), knowledge of which may enhance adherence if addressed.

    Pulmonary hypertension (PH) among heart transplant recipients is associated with an increased risk of mortality. Pulmonary hemodynamics improves after left ventricular assist device (LVAD) implantation; however, the impact of PH before total artificial heart (TAH) implantation on posttransplant hemodynamics and survival is unknown. This is a single center retrospective study aimed to evaluate the impact of TAH implantation on posttransplant hemodynamics and mortality in two groups stratified according to severity of PH: high (≥3 Woods units [WU]) and low (heart catheterization performed at baseline (before TAH) and posttransplant at 1 and 12 months. Patients in the high PVR group (n = 12) experienced improvement in PVR (baseline = 4.31 ± 0.7; 1-month = 1.69 ± 0.7, p heart transplantation (HT), but remained elevated. There was no significant difference in survival between the two groups at 12 months follow-up. Patients with high PVR who are bridged to transplant with TAH had improvement in PVR at 12 months after transplant, and the degree of PVR did not impact posttransplant survival.

    The clinical relevance of ambulatory blood pressure monitoring (ABPM) for risk stratification in renal transplant patients still remains poorly defined. We investigated the association between clinic and ABPM with an established biomarker of atherosclerosis (intima-media thickness [IMT] by echo-color Doppler) in a large, inclusive survey (n = 172) in renal transplant patients at a single institution. Forty-two patients (24%) were classified as hypertensive by ABPM criteria and 29 (17%) by clinic blood pressure (BP) criteria. Average daytime and nighttime BP was 126 ± 12/78 ± 9 mm Hg and 123 ± 13/74 ± 10 mm Hg, respectively. Forty-five patients (26%) were classified as hypertensive by the daytime criterion (>135/85 mm Hg) and a much higher proportion (n = 119, 69%) by the nighttime criterion (>120/70 mm Hg). Sixty-two patients (36%) had a night-day ratio of 1 or greater, indicating clear-cut nondipping. The average nighttime systolic BP (r = 0.24, P = 0.001) and the night-day systolic BP ratio (r = 0.23, P = 0.002) were directly related to IMT, and these associations were much more robust than the 24-hour systolic BP-IMT relationship (r = 0.16, P = 0.04). Average daytime BP and clinic B were unrelated to IMT. In a multiple regression analysis adjusting for confounders, the night-day systolic BP ratio maintained an independent association with IMT (β = 0.14, P = 0.04). In renal transplant patients, the prevalence of nocturnal hypertension by far exceeds the prevalence of hypertension as assessed by clinic, daytime, and 24-hour ABPM. Nighttime systolic BP and the night-day ratio but no other BP metrics are independently associated with IMT. Blood pressure during nighttime may provide unique information for the assessment of cardiovascular risk attributable to BP burden in renal transplant patients.

    The aim of this study was to analyse the causes of death after liver transplantation in order to find and to avoid preventable fatal complications if possible. Between September 1988 and September 1993 415 orthotopic liver transplantations in 382 patients were performed at the Rudolf Virchow University Hospital in Berlin. During the same interval 41 (10.7%) of these patients died. Their clinical records were reviewed. The main cause of death was infection (29.3%), followed by recurrent malignancy (21.9%). Less patients died because of hepatitis B-reinfection (14.6%), chronic rejection (7.3%), hemorrhage (7.3%), cardiac failure (7.3%), trauma (4.8%), hypoxia (4.8%) and recurrence of alcoholic liver disease (4.8%). There was a wide spectrum of opportunistic infectious agents with CMV and Pneumocystis carinii being the most important pathogenic organisms. Only one isolated bacterial infection as principle cause of death was found. In all fatal infections the lung was the primary site of infection, 7 patients additionally developed sepsis. Altogether 75 patients (19.6%) with hepatitis B-cirrhosis were transplanted. Six of them (8%) developed a fatal hepatitis B-reinfection. Malignancy was the indication for OLT in 41 patients (10.7%). Six of these patients (14.6%) died because of recurrent tumor. Regarding the whole series, most deaths occurred four to twelve months (58.5%) and only five (12.2%) during the first month after OLT. Recurrence of primary disease is an important factor regarding total mortality. Therefore it is necessary to practise a careful selection of liver transplant recipients. In the future more attention needs to be drawn towards prevention, identification and management of opportunistic infections.

    Islet transplantation is a recognized treatment option for select patients with type I diabetes mellitus. However, islet infusions from multiple donors are often required to achieve insulin independence. Ideally, insulin independence would be achieved routinely with only a single donor. Identification of factors associated with insulin independence after single-donor islet transplantation may help to select recipient-donor combinations with the highest probability of success. Subjects undergoing islet transplantation at a single center (Edmonton, Canada) between March 1999 and August 2013 were included. Recipient, donor, and transplant characteristics were collected and compared between recipients who became insulin independent after one islet transplantation and those who did not. Thirty-one patients achieved insulin independence after a single-donor islet transplantation, and 149 did not. Long-term insulin-free survival was not different between the groups. Factors significantly associated with single-donor success included recipient age, insulin requirement at baseline, donor weight, donor body mass index, islet transplant mass, and peritransplant heparin and insulin administration. On multivariate analysis, pretransplantation daily insulin requirements, the use of peritransplantation heparin and insulin infusions, and islet transplant mass remained significant. We have identified clinically relevant differences defining the achievement of insulin independence after single-donor transplantation. Based on these differences, a preoperative insulin requirement of less than 0.6 U/kg per day and receiving more than 5,646 islet equivalents (IEQ)/kg have a sensitivity of 84% and 71% and specificity of 50% and 50%, respectively, for insulin independence after single-donor islet transplantation. With ideal patient selection, this finding could potentially increase single-donor transplantation success and may be especially relevant for presensitized subjects or those who

    Full Text Available Introduction. Nowadays anti-inflammatory and immunosuppressive therapy has significantly improved the quality of life and prognosis of rheumatoid arthritis (RA. Nevertheless, there are still many patients with progressive rheumatoid inflammation, resulting in the destruction of joints. Cell therapy seems like a promising direction in rheumatology. The aim of our research was to evaluate the efficacy of fetal chondrocyte transplantation in patients with RA.Methods. We examined 60 patients with rheumatoid arthritis (I - III stages between 20 and 63 years of age. They were divided into 2 groups: the first group underwent the fetal chondrocytes transplantation (n = 40, and the second was a control group who got conservative therapy (n = 20. Donor cells were taken from the chondrogenic layer of the humerus or femur heads and hip condyles of human embryos in gestation for 17-20 weeks. A suspension of fetal chondrocytes injected into affected areas of the articular surfaces under X-ray control. Cell viability was determined before the injection. Efficacy of the therapy was assessed by clinical, instrumental, and laboratory tests. This clinical trial was allowed by The Ministry of Public Health and Ethics Committee. All of our patients gave informed consent for the fetal chondrocytes transplantation.Results. Evaluation of the clinical manifestations of RA in the first group of patients showed 3.7 times decrease in pain and 1.6 times relief of synovitis. Complete reduction of contracture was observed in 82% of patients in the first group. Morphometric changes in X-ray demonstrated inhibition of the destruction in articular cartilage and surfaces of bones after transplantation of fetal chondrocytes. The dynamics of morphological changes in synovium showed 2.5 times reduction of the inflammatory reaction. Transplantation of fetal chondrocytes led to a significant reduction in ESR, CRP, fibrinogen , γ-globulin after a period of 12 months (p < 0

    Full Text Available Neisseria lactamica, a commensal, has been very rarely reported to cause diseases in immunocompromised hosts. In medical literature, there is only one report of a cavitatory lung lesion caused by it. The patient was a kidney transplant recipient. Neisseria lactamica was found to be the cause of his pulmonary cavity and a desquamating rash on feet. With the rapidly spreading medical advance, more and more patients are getting organ transplants, so the population of immunocompromised people is on the rise. We expect more sinister and less expected organisms to cause diseases in patients who have organ transplants.

    Control of hypertension is often a problem in the management of end stage renal disease (ESRD). Multiple modalities of treatment are required to prevent cardiovascular and cerebrovascular mortality and morbidity. These include fluid and salt restriction, multidrug regimes and dialysis. We report a case of young 25 years old patient, admitted with chronic renal failure, complicated by malignant and refractory hypertension, not responding to hemodialysis and antihypertensive agent. During stay in hospital, patient also had intracerebral hemorrhage, fits due to uncontrolled hypertension requiring ventilatory support followed. Renal transplant was considered to be the final therapeutic modality. After gradual recovery, a successful live-related renal transplant was performed. As soon as good graft was established, the blood pressure settled and 4 of the 5 antihypertensives were withdrawn. After 2 weeks, patient was discharged in a stable condition with a total stay of about 2 months. (author)

    We sought to assess the relationship between survival, peak exercise oxygen consumption (VO(2)), and heart failure survival score (HFSS) in the current era of heart failure (HF) therapy. Based on predicted survival, HF patients with peak VO(2) 14 ml/min/kg (p = 0.04). Of the patients with peak VO(2) of 10 to 14 ml/min/kg, 55% had low-risk HFSS and exhibited 88% one-year event-free survival. One-year survival after transplantation was 88%, which is similar to the 85% rate reported by the United Network for Organ Sharing for 1999 to 2000. Survival for HF patients in the current era has improved significantly, necessitating re-evaluation of the listing criteria for heart transplantation.

    Sinusoidal obstruction syndrome (SOS) is one of the life-threatening complications caused by endothelial damage to the hepatic sinusoids after hematopoietic stem cell transplantation. However, a satisfactory treatment for SOS has not yet been established. Defibrotide has anti-thrombotic, anti-ischemic, anti-inflammatory, and thrombolytic properties without systemic anticoagulant effects. We treated eight post-transplant SOS patients with defibrotide. Three patients responded to the therapy and the initial response was observed within a week. In addition to the improvement of liver function, rapid recovery of response to diuretic drugs followed by the improvement of renal function was observed. All of the five patients with respiratory dysfunction died despite administration of defibrotide, suggesting that early treatment might lead to better outcomes. There were no severe adverse effects directly due to defibrotide administration. Defibrotide seems to be a promising treatment for SOS, and the initiation of a clinical study in Japan would be important.

    With the introduction of lung allocation score (LAS), increasingly sicker patients are undergoing lung transplantation (LT). This study was conducted to determine the time trends in need for dialysis after LT, identify variables independently associated with need for dialysis, and evaluate its association with 1- and 5-year mortality. We queried the United Network of Organ Sharing database for adult patients undergoing LT between 1994 and 2014. We excluded patients with simultaneous dual organ transplantation and where data regarding the need for dialysis were not available. Time trends in the yearly incidence of the need for dialysis showed a gradual increase (P = .012). In the post-LAS era, ethnicity, underlying diagnosis, estimated GFR 35 mm Hg, ventilator or extracorporeal membrane oxygenation support at LT, and >20% increase in serum creatinine between listing and match were independently associated with the need for dialysis. Patients with need for dialysis had significantly increased hazard of 1-year (n = 13 849; adjusted hazard ratio, 95% CI:7.23, 6.2-8.4, P need for early dialysis after LT, and these patients have significantly worse early and late survival. Several pre-transplant recipient characteristics are independently associated with the need for dialysis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full text: Urinary tract obstruction following renal transplantation often presents a diagnostic dilemma, as some patients with equivocal investigations subsequently show improvement following stenting. The purposes of this study were to (1) establish a normal range of renal output efficiency (ROE) in transplants, and (2) assess the usefulness of MAG3 diuresis renography and ROE in suspected allograft obstruction. Twenty-two renal transplant patients with stable function and no evidence of hydronephrosis on serial ultrasound had a diuretic MAG3 scan with calculation of ROE. Three patients with proven graft obstruction underwent the same scanning procedure. Methodology was as follows: (1) 60 MBq of 99m Tc-DTPA GFR was performed (single injection-dual blood sample method); (2) patients were then prehydrated with either oral or IV fluid; (3) 10 min prior to scanning, intravenous Frusemide 20-80 mg (dose depending on renal function) was injected, and then (4) 200 MBq of MAG3 for a 20 min scan. The studies were then qualitatively and quantitatively reviewed to assess uptake and excretion, and the ROE was calculated. The mean ROE for the twenty-two normal renal transplant patients was 85.7% ± 4.1% (range 78 - 90%). Technetium-99m-DTPA GFR was 55.5 mL/min/1.73m 2 (range 27 to 83). The MAG3 scans in the three obstructed patients were equivocal for obstruction but the ROE values of 59%, 68% and 75% were more than 2.5 standard deviations below our calculated normal mean. The 99m Tc-DTPA GFRs were 61,17 and 57 mL/min/1.73m 2 , respectively. Thus, in normal grafts the ROE should exceed 78 per cent. Our data suggest that ROE may be a useful addition to standard scintigraphic parameters in diagnosis of graft obstruction

    Mycophenolate mofetil (MMF) is used to prevent acute rejection following solid organ transplantation in transplant centers all over the world. Patients from different ethnic backgrounds are treated with this drug, for which therapeutic drug monitoring (TDM) has not become the standard of practice in most centers. Whether or not some ethnic groups require a different MMF dose has been a topic of debate in recent years. In this review, it is shown that Asian patients, compared with Caucasian patients, with a comparable MMF dose reach higher mycophenolic acid (MPA) exposure. Also clinical experience points toward more adverse events in case of treatment with 1 g MMF bid in Asian patients, and therefore, for this ethnic group, a lower maintenance dose seems justified. In contrast, African American patients reach similar drug concentrations as Caucasians patients receiving the same MMF dose, but due to immunological reasons, they require a higher MMF dose to reach comparable acute rejection incidences. When TDM is performed, clinicians can correct the dose and compensate for interethnic differences in drug exposure. Otherwise, it is important to choose the right dose. This optimal dose is 20-46% lower in Asian transplant recipients than in Caucasian or African American patients. © 2014 Steunstichting ESOT.

    Objective: To report the initial data on allogeneic peripheral blood stem cell transplantation for haematogical malignancies in Pakistan. Patients and Methods: Patients with haematological malignancies were included who had received allogeneic PBSC transplantation of Filgrastim (rhG-CSF) mobilized peripheral blood stem cells from HLA-identical siblings (except one 5/6 antigen sibling) with Busulphan and Cyclophosphamide standard conditioning therapy in all patients. No patient received antibiotics for gut decontamination. Empirical antibiotics included Ceftriaxone and Amikacin for febrile neutropenia, oral Itraconazole for antifungal prophylaxis while oral acyclovir was used for antiviral prophylaxis. All donors and recipients were CMV IgG positive Cyclosporin A / Methotrexate were given for graft versus host disease (GvHD) prophylaxis. Stem cells were harvested using Haemonetics MCS+ cell separator. All patients received G-CSF starting from day +4 until their neutrophil count rose to normal. Results: There were 21 patients with age range of 8-38 years and male to female ratio of 2:1. Engraftment was achieved in all patients; median time to absolute neutrophil count of > 0.5 x 10/sup 9/I was 10 days (range 8 -12 days) and platelet count of > 20 x 10/sup 9/1 was 14 days (12-17 days). Acute graft versus host disease (aGvHD) was seen in 7 patients; one patient had grade IV skin and hepatic GvHD; another patient had grade III gut GvHD, grade II GvHD was seen in 3 patients while grade I skin aGvHD was seen in 2 patients. Median hospital stay was 34 days. Treatment related mortality was seen in 3 patients (18%). Chronic GvHD was seen in 5 patients. Four more patients died during the follow-up period. Malaria was seen in 2 while tuberculosis developed in one case. Relapse was seen in 2 patients. The estimated probability of survival at one hundred day, at one year and five years was 82, 47 and 40 percent respectively. Conclusion: Haematopoietic stem cell transplant

    Literature has shown that information, education and support had a beneficial effect on how the patients and their family lived through the transplant process. In our daily practice, we are permanently confronted with requests for information and psychological adjustments from our patients. Do the needs of this population meet the representations of the care-takers? Our theoretical framework is based on the theories of Maslow and Callista Roy, on the concept of social representations according to Moscovici and on the steps of the transplant process. To carry out this survey, we used a questionnaire which we gave to the patients at the different phases of the graft and to the nurses of the services involved in the transplant. There was a similarity of the results between the two populations, despite some differences for certain items. The development of a programme for information and for education will enable an improvement of the care quality thanks to the adaptation of knowledge to the needs of the transplanted patients.

  8. LAPAROSCOPIC RECONSTRUCTION OF THE URINARY TRACT IN PATIENTS WITH URETERAL STRICTURE AFTER KIDNEY TRANSPLANTATION

    Full Text Available Aim. Ureteral obstruction secondary to ischemia is the most common urologic complication of kidney trans- plantation. Pyeloureteral anastomosis with recipient ureter has shown most satisfactory long-term results in its management. Existing urinary infection and immunosupression determine the high risk of wound complications. We have experience more than 50 reconstructive procedures of urinary tract after kidney transplantation by open surgery during 25 years. Till last time this procedure has been performed through open surgery. Method. We used pyeloureteral anastomosis with recipient ureter in two patients with ureteral stricture after kidney transplantation by laparoscopic approach. The operations lasted 215 and 275 min respectively. In both cases the surgery was per- formed after percutaneous nephrostomy because of deterioration of transplanted kidney function. Internal stent was indwelled laparoscopicaly. No drain tube was left. Results. The nephrostomy tubes were removed after 10 and 7 days respectively. The stents were removed after 27 and 20 days respectively. No complications were seen during the surgery and postoperative period. Now serum creatinine level is 0.12 mmol/l and 0.15 mmol/l after 15 and 12 months after surgery respectively. Conclusion. In spite of some difficulties related with topographic land- marks and severe tissues fibrosis after transplantation laparoscopic pyeloureterostomy in transplanted kidney is safe and feasible procedure. The main advantage is absence of risk of most serious complications related with wound infection in immune compromised patients. Moreover, early recovery to usual activity and diet facilita- tes to prevent pulmonary infections and to normalize intestinal absorbability of the immunosuppressive drugs.

    Despite our knowledge of barriers to the early stages of the transplant process, we have limited insight into patient-reported barriers to the prekidney transplant medical evaluation in populations largely at-risk for evaluation failure. One-hundred consecutive adults were enrolled at an urban, Midwestern transplant center. Demographic, clinical, and quality of life data were collected prior to patients visit with a transplant surgeon/nephrologist (evaluation begins). Patient-reported barriers to evaluation completion were collected using the Subjective Barriers Questionnaire 90-days after the initial medical evaluation appointment (evaluation ends), our center targeted goal for transplant work-up completion. At 90 days, 40% of participants had not completed the transplant evaluation. Five barrier categories were created from the 85 responses to the Subjective Barriers Questionnaire. Patient-reported barriers included poor communication, physical health, socioeconomics, psychosocial influences, and access to care. In addition, determinants for successful evaluation completion included being of white race, higher income, free of dialysis, a lower comorbid burden, and reporting higher scores on the Kidney Disease Quality of Life subscale role-emotional. Poor communication between patients and providers, and among providers, was the most prominent patient-reported barrier identified. Barriers were more prominent in marginalized groups such as ethnic minorities and people with low income. Understanding the prevalence of patient-reported barriers may aid in the development of patient-centered interventions to improve completion rates.

    To identify the impact of the presence of patent foramen ovale (PFO) in patients undergoing liver transplantation. Twenty-seven pre-liver transplant patients who had a PFO (PFO group) were identified and compared with 61 patients without PFO (NoPFO group). Patients were matched according to age, gender and cause of liver disease. The diagnosis of PFO was made by transthoracic echocardiography prior to liver transplantation. Patient baseline characteristics and complications during the early post-transplant period were analyzed. The mean age in the PFO group was 47 ± 14 (range 18-68) yr and 50 ± 11 (range 12-65) yr in the NoPFO group. The PFO group had a mean model for end-stage liver disease (MELD) score of 15 ± 10 whereas in the NoPFO group the MELD score was 19 ± 10 (p = 0.08). There were non-significant differences in echocardiographic parameters between groups. Duration of mechanical ventilation and the incidence of neurological complications were similar. Thirty-day mortality rate was similar in both groups; only one patient in the NoPFO group died within the first 30 days post-transplantation. The presence of PFO in patients with end-stage liver disease undergoing liver transplantation does not appear to affect patient outcomes during the peri-operative period. © 2010 John Wiley & Sons A/S.

    Cardiac retransplantation is a controversial procedure due to the disparity between donor heart demand and supply. Of 7,290 patients undergoing primary cardiac transplantation between January 1990 and December 1999 at 42 institutions contributing to the Cardiac Transplant Research Database (CTRD), 106 patients later underwent a second and 1 patient a third cardiac transplant procedure. The actuarial freedom from retransplantation was 99.2% and 96.8% at 1 and 10 years, respectively. Reasons for retransplantation included early graft failure (n = 34), acute cardiac rejection (n = 15), coronary allograft vasculopathy (CAV, n = 39), non-specific graft failure (n = 7), and miscellaneous (n = 10). The only risk factor associated with retransplantation was younger age, reflecting the policy of preferential retransplantation of younger patients. Survival after retransplantation was inferior to that after primary transplantation (56% and 38% at 1 and 5 years, respectively). Risk factors associated with death after retransplantation included retransplantation for acute rejection (p = 0.0005), retransplantation for early graft failure (p = 0.03), and use of a female donor (p = 0.005). Survival after retransplantation for acute rejection was poorest (32% and 8% at 1 and 5 years, respectively) followed by retransplantation for early graft failure (50% and 39% at 1 and 5 years, respectively). Survival after retransplantation for CAV has steadily improved with successive eras. The results of retransplantation for acute rejection and early graft failure are poor enough to suggest that this option is not advisable. However, retransplantation for CAV is currently associated with satisfactory survival and should continue to be offered to selected patients.

    Interferon regulatory factors (IRFs) can play a critical role in the regulation of many facets of innate and adaptive immune responses through transcriptional activation of type I interferons, other proinflammatory cytokines, and chemokines. However, their roles in transplantation immunity still remain to be elucidated. To evaluate the time course of mRNA expression of all 9 members of IRFs family of transcription factors during liver allograft acute rejection. Blood samples of 19 patients with autoimmune hepatitis receiving liver transplants were collected on days 1, 3, 5, and 7 post-transplantation. The patients were followed for 6 months after transplantation and divided into two groups of acute rejection (AR) (n=4) and non-acute rejection (non-AR) (n=15). All of the studied transcription factors were down-regulated in AR-group on days 3, 5, and 7 post-transplantation compared to non-AR group. The mean±SEM IRF5 on day 7 post-transplantation was significantly (p=0.005) lower in AR-group than in non-AR group (0.7±0.21 vs . 1.91±0.27, respectively); expression of other IRFs family members was not significantly different between the two groups on days 3, 5, and 7 post-transplantation. IRF5 may have an important role during the acute rejection of liver transplants.

    Patients undergoing a bone marrow stem cell transplant (BMT) face various risk factors. Analyzing data from past transplants could enhance the understanding of the factors influencing success. Records up to 120 measurements per transplant procedure from 1751 patients undergoing BMT were collected (Shariati Hospital). Collaborative filtering techniques allowed the processing of highly sparse records with 22.3% missing values. Ten-fold cross-validation was used to evaluate the performance of various classification algorithms trained on predicting the survival status. Modest accuracy levels were obtained in predicting the survival status (AUC = 0.69). More importantly, however, operations that had the highest chances of success were shown to be identifiable with high accuracy, e.g., 92% or 97% when identifying 74 or 31 recipients, respectively. Identifying the patients with the highest chances of survival has direct application in the prioritization of resources and in donor matching. For patients where high-confidence prediction is not achieved, assigning a probability to their survival odds has potential applications in probabilistic decision support systems and in combination with other sources of information.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    There is a growing concern about the therapeutic equivalence of the generic tacrolimus formulation (GEN Tacrolimus) to the reference tacrolimus (REF Tacrolimus) in solid organ transplantation. A prospective, randomized study of 126 de novo renal transplant patients was conducted to compare the efficacy, safety and pharmacokinetic (PK) profiles between GEN tacrolimus (n = 63) and REF tacrolimus (n = 63). The PK of tacrolimus was evaluated on Day 10 and 6 months under steady-state condition. Crossover study was carried out in 66 patients at 6 months. On Day 10, 117 patients completed PK profiles (54 GEN tacrolimus and 63 REF tacrolimus) and GEN tacrolimus showed comparable C(0) (9.8 ± 2.5 versus 9.7 ± 3.0 ng/mL, P = 0.80) but significantly higher dose-normalized C(max) (309.1 ± 191.9 versus 192.5 ± 95.2 ng/mL/mg/kg, P PK profiles evaluated at 9 months showed that generic substitution also resulted in an 'early and high C(max)'. Efficacy and safety data were comparable over the 9-month study period. Therapeutic equivalence and the PK of GEN tacrolimus should be evaluated in patients undergoing de novo renal transplantation.

    Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

    The aim of this study was to evaluate the influence of Saccharomyces boulardii on the intestinal permeability, laboratory parameters and MELD and Child-Pugh severity scores in cirrhotic patients eligible for liver transplantation. Eighteen patients followed in a Transplant Outpatient Clinic were evaluated immediately before the beginning of treatment, after a 30-day period of treatment period with probiotics and at the end of the second study month (after a thirty-day period without probiotics). Fifteen healthy controls also underwent the intestinal permeability test (lactulose/mannitol). Before the probiotic, the median lactulose/ mannitol ratio was greater in the cirrhotic patients (0.0209, range 0.0012-0.1984) compared to the healthy controls (0.0030, range 0.0020-0.0013) (p boulardii, there was no improvement in intestinal permeability or significant differences in the laboratory parameters for the three evaluations. Patients eligible for liver transplants presented with increased intestinal permeability compared to healthy controls. A thirty-day treatment with S. boulardii did not improve this intestinal permeability or the severity scores, nor did it impact the laboratory parameters. Copyright AULA MEDICA EDICIONES 2014.

    2013-01-01

    Full Text Available Introduction. Tumescent local anesthesia (TLA is widely used for ambulatory surgery. Patients with transplanted organs are on immunosuppressive therapy and with risk for organ rejection or severe infection. Case report. Saphenectomy with phlebectomy on the left leg under TLA was performed in a patient with kidney transplantation performed four years ago. A combination of 35 mg of 1% prilocaine-hydrochloride, 5 mL of 8.4% sodium bicarbonate and 500 μg of epinephrine in 460 mL of normal saline was used for TLA. Overall 750 mL of the solution was used. The patient had satisfactory postoperative analgesia and was discharged home on the same day. Blood levels of urea, creatinine, estimated glomerular filtration rate (eGFR and tacrolimus concentration, measured preoperatively and on the second postoperative day, were in a regular range. Prilocaine blood concentrations determined on the 4th, 10th and 16th postoperative hours, were below toxic levels. Conclusion. TLA in a kidney-transplanted patient performed for saphenectomy with phlebectomy proved to be a safe and reliable anesthesia method.

These species are vasotropic, causing rapid onset of tissue infarctions and necrosis and subsequent thrombosis by invading vascular bed. The disease spectrum ranges from involvement of skin, sinuses, lung, and brain to disseminated and mostly fatal infections, especially in immunocompromised hosts. Here, we present a case of a fatal disseminated mucormycosis in a 56-year-old female who had deceased donor renal allograft transplantation ~2 weeks prior to presentation. She presented with shortness of breath and dry cough. Despite being on broad-spectrum antibiotics/antifungals and proper management by transplant, infectious disease, and primary team, she died within 3 weeks of admission. Autopsy showed disseminated mucormycosis of lungs and thyroid. Disseminated infection within 2 weeks of solid organ transplantation in this patient was one of the rare features of mucormycosis.

    In 2013, the National Heart, Lung, and Blood Institute assembled a working group on epidemiology and population sciences from its Advisory Council and Board of External Experts. The working group was charged with making recommendations to the National Heart, Lung, and Blood Advisory Council about how the National Heart, Lung, and Blood Institute could take advantage of new scientific opportunities and delineate future directions for the epidemiology of heart, lung, blood, and sleep diseases. Seven actionable recommendations were proposed for consideration. The themes included 1) defining the compelling scientific questions and challenges in population sciences and epidemiology of heart, lung, blood, and sleep diseases; 2) developing methods and training mechanisms to integrate "big data" science into the practice of epidemiology; 3) creating a cohort consortium and inventory of major studies to optimize the efficient use of data and specimens; and 4) fostering a more open, competitive approach to evaluating large-scale longitudinal epidemiology and population studies. By building on the track record of success of the heart, lung, blood, and sleep cohorts to leverage new data science opportunities and encourage broad research and training partnerships, these recommendations lay a strong foundation for the transformation of heart, lung, blood, and sleep epidemiology. © The Author 2015.

    To compare dietary intake and health-related quality of life approximately 6 to 10 weeks after renal transplantation in patients living at home and at a patient hotel, and how the patients were following a heart-healthy diet according to the current American Heart Association guidelines. Cross-sectional observational study. Outpatient clinic at Rikshospitalet University Hospital, Norway. Forty renal transplant patients, 20 patients (14 men and 6 women) in both groups. There were 4 diabetic patients in each group. Dietary intake was assessed by 4-day dietary records. Health-related quality of life was investigated by the SF-36 questionnaire. The main outcome variables were daily energy intake and intakes of protein, total fat, saturated fat, cholesterol, fiber, and fruit and vegetables. The variables were tested by 2-sample t-tests, and significance was set at.05. There was no statistically significant difference in daily energy intake between the groups (P =.08), but there were significantly higher daily intakes of protein (P =.003), total fat (P =.03), monounsaturated fat (P =.02), cholesterol (P =.04), fiber (P =.02), calcium (P =.03), and fruit and vegetables (P =.03) in the group living at the patient hotel. The mean intake of saturated fat was 14.5% of total energy in the group living at home and 14.6% in the group living at the patient hotel. There were no significant differences in health-related quality of life between the groups. The results suggest that there are differences in dietary intake in renal transplant patients living at home compared with those at a patient hotel. It seems that neither of the groups follows current guidelines for reducing the risk of cardiovascular disease.

    Low posaconazole plasma concentrations (PPCs) are frequently encountered in allogeneic hematopoietic stem cell transplant (HSCT) patients, due to variable gastrointestinal absorption. In this study, the impact of intestinal mucositis on posaconazole exposure is investigated. A prospective pharmacokinetic study was performed including allogeneic HSCT patients receiving posaconazole prophylaxis with the oral suspension or tablets. Steady state PPCs were determined using high-performance liquid chromatography-fluorescence detection at the day of transplantation (=day 0), day +7, and +14. Citrulline was measured using liquid chromatography-tandem mass spectrometry to evaluate severity of mucositis, at baseline (day -7 or -6), and at day 0, +7 and +14. Additionally, citrulline plasma concentrations and steady state trough PPCs were determined in hematological patients without HSCT or mucositis. Thirty-four HSCT patients received posaconazole oral suspension together with 25 cL of Coca Cola, 6 HSCT patients received posaconazole tablets and 33 hematological patients not receiving HSCT received posaconazole oral suspension. The median (interquartile range) average PPC was 0.26 mg/L (0.17-0.43), 0.67 mg/L (0.27-1.38), and 1.08 mg/L (0.96-1.38), with suspension in HSCT patients, suspension in hematological patients and tablets in HSCT patients, respectively. A higher trough PPC was encountered with the oral suspension when citrulline plasma concentrations were above 10 μmol/L compared to values below 10 μmol/L (p < 0.001), whereas for tablets, average PPCs remained high with citrulline plasma concentrations below or above 10 μmol/L (p = 0.64). Posaconazole tablets should be preferred to suspension in HSCT patients immediately after transplantation to prevent insufficient plasma exposure due to intestinal mucositis.

    To evaluate by US and CT the incidence and complications of acquired cystic kidney disease (ACKD) in dialysis and renal transplant patients and to compare the effectiveness of US and CT in the diagnosis of this entity. This study was prospectively performed in 70 dialysis patients and 13 renal transplant patients, and excluded any with multiple renal cysts or polycystic kidney disease, on as seen on initial films. US were obtained in all patients, and CT scans were randomly obtained in 27 who had been on dialysis for 3 years or more; all these US and CT scans were analyzed, with particular emphasis on whether or not cysts were present. In order to correlate the numbers of cysts with duration of dialysis, all patients were assigned to one of three groups, according to the number of cysts found (group 1, 0; group 2, 1-4; group 3, >4). Only group 3 was diagnosed as suffering from ACKD. In order to compare the cyst-detection capability of US with that of CT, 27 dialysis patients who had undergone US and CT were divided into four groups according to the number of cysts found (grade 1, 0; grade 2, 1-4; grade 3, 5-10; grade 4, >10). Seventy dialysis patients were divided according to the results of US, as follows : group 1, 20%; group 2, 47.1%; group 3, 32.9%. The mean duration of dialysis in group 1 (31.9 months) was statistically different from that in group 2 (50.6 months) and in group 3 (95.8 months) (p < 0.000). Thirteen renal transplant patients were divided as follows : group 1, 61.5%; group 2, 38.5%; group 3, 0%. In dialysis patients with ACKD, complications noted were renal cell carcinoma (n=1), hemorrhagic cysts (n=2), and hematomas (n=2). Among the 27 dialysis patients who underwent CT, this and US showed an equal grade of cystic change in 53.7%, while CT showed a higher grade in 46.3%. The detection rate of ACKD in these 27 patients was 46% on US and 63% on CT. A prolongation of dialysis corresponded to an increased incidence of ACKD; renal neoplasm and

    Cyclosporin and tacrolimus remain the cornerstone immunosuppressive drugs in organ transplantation. Dosing and monitoring these drugs is based on pharmacokinetic protocols, but measuring a pharmacodynamic parameter, calcineurin phosphatase (CaN) activity, could be a valuable supplement...... in determining optimal doses. Forty stable renal transplant patients were investigated three times in a 6-month period. Blood samples were drawn at 0, 1, 2, 3 and 4 h after oral intake of tacrolimus (FK) or cyclosporin at days 1 and 180. At day 90, one blood sample at trough level (FK) or C2 level (cyclosporin A...... at days 1 and 180 were the same for both drugs. Furthermore, we found that patients treated with tacrolimus or cyclosporin displayed different calcineurin activity profiles. We found that cyclosporin displayed greater calcineurin inhibition than tacrolimus. We have demonstrated that the two drugs exert...

    Full Text Available Objective To investigate the epidemiological characteristics of BK virus (BKV infection in living renal transplantation patients, and analyze the risk factors of BKV infection and BKV nephropathy (BKVN. Methods The BKV DNA load in urine and blood samples of 43 renal transplant recipients, who had received renal transplantation in 309 Hospital from Feb. 2012 to Feb. 2013, was determined at preoperative period and 0.5, 1, 3, 6, 9, 12 and 15 months after transplantation. Meanwhile, the biopsy of grafted kidney was performed in those patients with continuously elevated serum creatinine and those with higher BKV DNA load. Patients were divided into 3 groups as follows according to the test results: BK viruria group, BK viremia group and pathologically diagnosed BKVN group. Data of each group were then recorded, including gender, age, postoperative diabetes (PTDM, acute rejection (AR, delayed recovery of graft function (DGF, postoperative pulmonary infection, preoperative immune induction therapy, postoperative immunosuppressive regimen, and other information. The risk factors for postoperative BKV infection and BKVN were analyzed. Results After an average of 15-month follow-up, it was found that the incidence of BKV viruria was 46.5%, that of BKV viremia was 14.0%, and that of BKVN was 2.3%. Sixth month after transplantation was found to be the peak time of viruria and viremia. FK506 was significantly associated with viremia in living donor renal transplantation. The immunosuppressive regimen was the immune related independent risk factor for BK viremia developing BKVN after living renal transplantation. Conclusion The incidence of BK viremia and BKVN is lower in living donor renal transplantation than in cadaver renal transplantation, but that of viruria is similar in both groups. Immunosuppressive scheme based on FK506 is an immune related independent risk factor leading to BK viremia proceeding to BKVN in living donor kidney

  8. Beneficial Effect of Conversion to Belatacept in Kidney-Transplant Patients with a Low Glomerular-Filtration Rate

    Full Text Available Belatacept has been found to be efficient at preserving good kidney function in maintenance kidney-transplant patients. Herein, we report on the use of belatacept as a rescue therapy for two kidney-transplant patients presenting with severe adverse events after treatment with calcineurin inhibitors (CNIs and mammalian target-of-rapamycin (mTOR inhibitors. Two kidney-transplant patients developed severely impaired kidney function after receiving CNIs. The use of everolimus was associated with severe angioedema. Belatacept was then successfully used to improve kidney function in both cases, even though estimated glomerular-filtration rate before conversion was <20 mL/min. These case reports show that belatacept can be used as a rescue therapy, even if kidney function is very low in kidney-transplant patients who cannot tolerate CNIs and/or mTOR inhibitors.

    Purpose: To evaluate the patterns and timing of initial recurrence in patients with Hodgkin's lymphoma (HL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplantation to enhance our understanding of the natural history of this disease and its modern treatment strategies and to direct approaches to disease surveillance. Methods and Materials: The records of 69 patients with HL who had undergone high-dose chemotherapy with autologous stem cell transplantation in our center between May 1992 and June 2006 were analyzed. The initial diagnosis had been made between April 1982 and January 2005 at a median patient age of 33 years (range, 19-65). The patients were segregated according to the initial stage (Stage I-II vs. III-IV). Results: Early-stage HL patients developed a relapse at a median of 2.1 years (range, 0.5-10.3), with 91% of relapses at the initial disease site, 71% of which (65% overall) were only in previously involved sites. Advanced-stage HL patients developed a relapse at a median of 1.5 years (range, 0.6-10.5), with 97% at the initial site, 71% of which (69% overall) were only in previously involved sites. Single-site relapses occurred in 47% of early- vs. 26% of advanced-stage patients, and extranodal relapses occurred in 12% of early- vs. 31% of advanced-stage patients. Conclusions: Almost all patients with HL who develop relapse and subsequently undergo high-dose chemotherapy with autologous stem cell transplantation initially developed recurrence in previously involved disease sites. Early-stage HL relapses often occurred in single sites, and advanced-stage disease relapses were more likely in multiple and extranodal sites. The interval to recurrence was brief, suggesting that the frequency of screening should be the greatest in the early post-therapy years.

    Soluble CD30 (sCD30) is a suggested marker for kidney transplantation outcomes. We investigated whether sCD30 serum levels are influenced by immunosuppression and whether they correlate with findings in protocol biopsies and with CD30 gene expression in peripheral blood mononuclear cells (PBMC). We studied 118 kidney transplant recipients that initially received tacrolimus (TAC) and, at month-3, were converted or not to sirolimus (SRL). sCD30 serum levels gradually declined after transplantation, being the decline more pronounced in the SRL group. CD30 gene expression in PBMC was higher in the SRL group than in the TAC group. Patients with IF/TA ≥ I in the month-24 protocol biopsy had higher sCD30 levels than patients without IF/TA, in the SRL group (P = .03) and in the TAC group (P = .07). CD30 + cells were observed in three out of 10 biopsies with inflammatory infiltrate from the SRL group. In mixed lymphocyte cultures, SRL and TAC diminished the number of CD30 + T cells and the sCD30 levels in the supernatant, but the effect of SRL was stronger. Overall, sCD30 levels are lower in SRL-treated patients, but the association between increased sCD30 levels and IF/TA at month-24 post-transplantation is stronger in SRL than in TAC-treated patients.

    Renal dysfunction occurs commonly in patients awaiting orthotopic liver transplantation (OLT) for end-stage liver disease. The use of simultaneous liver-kidney transplantation has increased in the MELD scoring era. As patients may recover renal function after OLT, identifying factors predictive of renal recovery is a critical issue, especially given the scarcity of available organs. Employing the UNOS database, we sought to identify donor- and patient-related predictors of renal recovery among 1720 patients with pre-OLT renal dysfunction and transplanted from 1989 to 2005. Recovery of renal function post-OLT was defined as a composite endpoint of serum creatinine (SCr) ≤1.5 mg/dL at discharge and survival ≥29 days. Pre-OLT renal dysfunction was defined as any of the following: SCr ≥2 mg/dL at any time while awaiting OLT or need for renal replacement therapy (RRT) at the time of registrati
