    13 previously untreated patients with poor prognosis non-Hodgkin's lymphoma (NHL) underwent high-dose therapy followed by autologous bone marrow transplantation (ABMT). All patients experienced a great cytoreductive effect and 9 of them reached a complete remission (mean duration 32 months). The best results were observed in patients with more limited disease and in those without symptoms. 7 patients still remain in complete unmaintained remission 15-46 months from the transplant. The probability of survival is 74% at 46 months. No therapy-related deaths were recorded. In differentiating our preliminary approach, we propose high dose therapy followed by ABMT as induction phase in patients with stage II and as consolidation after first line therapy in patients with stages III-IV. Further studies are warranted to determine which type of lymphoma may benefit more and which conditioning regimens may improve the remission rate.

    Muscle wasting occurs in renal recipients due to decreased physical performance, and decreased respiratory muscle strength may occur due to changes in structure and function. Data are scarce regarding the roles of sarcopenia and nutritional status on respiratory muscle function in these patients. Here, we evaluated interactions among peripheral muscle strength, sarcopenia, nutritional parameters, and respiratory muscle function in renal transplant recipients. Ninety-nine patients were prospectively enrolled between September and April 2016 at Baskent University. Forced vital capacity values (via pulmonary function tests), respiratory muscle strength (via maximal static inspiratory and expiratory pressures), and peripheral muscle strength (via hand grip strength test) were recorded. Nutritional parameters, fat weight, arm circumference, waist circumference, and C-reactive protein levels were also recorded. Of 99 patients, 68 were renal transplant recipients (43 men, mean age: 39.09 ± 10.70 y) and 31 were healthy participants (14 men, mean age: 34.94 ± 10.95 y). Forced vital capacity (P .05). No statistically significant relation was observed between biochemical parameters and maximal inspiratory and expiratory pressures (P ? .05). Respiratory function and peripheral muscle strength were significantly related in renal transplant recipients, with significantly lower peripheral muscle strength suggesting the presence of inadequate respiratory function. Peripheral and respiratory muscle training and nutritional replacement strategies could help to improve postoperative respiratory function.

    Background Common genetic variations influence rejection, infection, drug metabolism, and side effect profiles after pediatric heart transplantation. Reports in adults suggest that genetic background may influence post-transplant renal function. In this multicenter study we investigated the association of genetic polymorphisms (GP) in a panel of candidate genes on renal function in 453 pediatric heart transplant recipients. Methods We performed genotyping for functional GPs in 19 candidate genes. Renal function was determined annually after transplantation by calculation of glomerular filtration rate (eGFR). Mixed effects and Cox proportional hazard models were used to assess recipient characteristics and the effect of GPs on longitudinal eGFR and time to eGFR <60 mL/min/1.73m2. Results Mean age at transplantation was 6.2 ± 6.1 years and mean follow-up was 5.1 ± 2.5 years. Older age at transplant and black race were independently associated with post-transplant renal dysfunction. In univariate analyses, FASL (C-843T) T allele (p=0.014) and HO-1 (A326G) G allele (p=0.0017) were associated with decreased renal function. After adjusting for age and race, these associations were attenuated [FASL (p=0.075), HO-1 (p=0.053)]. We found no associations of other GPs, including GPs in TGFβ1, CYP3A5, ABCB1, and ACE, with post-transplant renal function. Conclusions In this multicenter, large sample of pediatric heart transplant recipients we found no strong associations between GPs in 19 candidate genes and post-transplant renal function. Our findings contradict reported associations of CYP3A5 and TGFβ1 with renal function and suggest that genotyping for these GPs will not facilitate individualized immunosuppression for the purpose of protecting renal function after pediatric heart transplantation.

    A nephrologist with expertise in ultrasonography noticed that patients with longstanding renal grafts had smaller spleens than subjects undergoing initial post-transplantation imaging. This putative finding prompted us to pursue a further investigation into splenic function based on Doppler ultrasound and hematologic parameters. We enrolled 47 patients with functioning long-standing kidney grafts, measuring longitudinal diameter of the spleen, hilar and intrasplenic peak systolic velocities (PSV), and hilar and intrasplenic resistivity indices of the splenic artery as well as mean arterial blood pressure (MAP). Giemsa-stained peripheral blood smears were examined for the presence of Howell-Jolly bodies (HJBs) using light microscopy. The patients were then divided into HJB present (HJ(+)) or absent (HJ(-)) groups for further comparison. The overall mean age of 21 females and 26 males was 47.8 ± 12.0 years, and the mean time after transplantation was 2750 ± 1818 days (range, 208-6446). HJBs were detected in 23/47 patients (48.9%). The intrasplenic artery PSV was significantly lower and MAP higher in the HJ(+) group (P < .05). There was no difference in spleen size between the groups. HJBs in peripheral blood red cells, an indicator of hyposplenism, was associated with reduced intrasplenic artery PSV, suggesting dysfunction, which may play a role in the known vulnerability of renal transplant recipients to infections.

    Objective. To investigate changes in serum pituitary-gonadal hormones and restoration of sexual and reproductive functions after successful kidney transplantation. Patients and Methods. Serum pituitary-gonadal hormones before and after kidney transplantation were measured in 78 patients with end-stage renal disease (ESRD) and in 30 healthy adults. Pre- and postoperative semen specimens of 46 male recipients and 15 male controls were collected and compared. Additional 100 married kidney transplant recipients without children were followed up for 3 years to observe their sexual function and fertility. Results. Serum PRL, LH, and T or E(2) levels gradually restored to the normal ranges in all kidney transplant recipients, and sperm density, motility, viability, and morphology significantly improved in the male recipients 4 months after successful kidney transplantation (P male recipients (55.93%) reobtained normal erectile function, and 49 kidney transplant recipients (61.25%) had children within the 3-year follow-up period. Conclusion. Successful kidney transplantation could effectively improve pituitary-gonadal hormone disturbance and sexual and reproductive dysfunctions of ESRD patients.

    Functional neuroimaging can provide insight into the neurobiological factors that contribute to the variations in individual hearing outcomes following cochlear implantation. To date, measuring neural activity within the auditory cortex of cochlear implant (CI) recipients has been challenging, primarily because the use of traditional neuroimaging techniques is limited in people with CIs. Functional near-infrared spectroscopy (fNIRS) is an emerging technology that offers benefits in this population because it is non-invasive, compatible with CI devices, and not subject to electrical artifacts. However, there are important considerations to be made when using fNIRS to maximize the signal to noise ratio and to best identify meaningful cortical responses. This review considers these issues, the current data, and future directions for using fNIRS as a clinical application in individuals with CIs. PMID:26883143

  11. IL-15 Harnesses Pro-inflammatory Function of TEMRA CD8 in Kidney-Transplant Recipients

    Full Text Available The involvement of TEMRA CD8 is evident in a large array of immunological conditions ranging from auto- to allo-immunity. Nevertheless, the factors leading to their accumulation and activation remain ill-defined and, efficient therapeutics to control their inflammatory response is lacking. Here, we show that IL-15-stimulated TEMRA from kidney-transplant (KT recipients promote inflammation by inducing the expression of CX3CL1 by endothelial cells in an IFN-γ- and TNF-α-dependent manner. The responsiveness of TEMRA to IL-15 is not restricted to chronic stimulation, as TEMRA from healthy volunteers respond earlier and faster when compared to effector memory (EM. IL-15 induces antiapoptotic signals and promotes proliferation dependent of PI3K/Akt, MAPK, and ERK pathways. Without ex vivo stimulation, TEMRA cells are metabolically more active than naive and EM, as shown by their high ATP reservoir and a high expression of genes involved in glycolysis, glutaminolysis, and the Pentose Phosphate Pathway. Upon stimulation, TEMRA adapt their metabolism by sustaining an increased mitochondrial respiration and glycolysis. Finally, we show that the inhibition of glycolysis is highly effective in preventing endothelial inflammation induced by TEMRA from KT recipients. Together, our findings highlight the metabolic fitness that tightly regulates the immune function of TEMRA in physiological and pathogenic situations.

    There are conflicting data regarding the effects of renal transplantation (RT) on uraemic autonomic dysfunction. Moreover, no study has examined the impact of physical training on the cardiac autonomic function in RT patients. Thus, we studied the effects of exercise training on heart rate variability (HRV) and arterial baroreflex sensitivity (BRS), which are sensitive markers of cardiac autonomic outflow, in RT recipients. Eleven patients (Exercise group-aged 52.1 ± 5.6 years) were studied before and after 6 months of exercise training. Twelve age- and sex- matched RT patients (Sedentary) and 12 healthy sedentary individuals (Healthy), who remained untrained, served as controls. At baseline and follow-up, all the subjects underwent cardiopulmonary exercise testing for the evaluation of peak oxygen consumption (VO2peak), a tilt test for the evaluation of BRS and baroreflex effectiveness index (BEI) and an ambulatory 24-h Holter monitoring for time- and frequency-domain measures of HRV. In the exercise group, VO2peak increased by 15.8% (P training. Specifically, the standard deviation of all normal-to-normal (NN) intervals (SDNN) significantly increased by 92.5%, the root-mean-square of the differences between consecutive NN intervals by 45.4%, the percentage value of NN50 count by 58.2%, the high-frequency by 74.8% and low-frequency spectral power by 41.6%, BRS by 43.7% and BEI by 57.3%. None of the variables studied was altered over time in either control group. The increased cardiorespiratory fitness by exercise training was associated with an improved BRS function and a modification of the sympathovagal control of HRV towards a persistent increase in parasympathetic tone. These alterations may lead to a better cardiovascular prognosis in RT recipients.

    Full Text Available Objectives: To determine the utility of pre-implantation renal biopsy (PIB to predict renal allograft outcomes. Methods: This is a retrospective review of all patients that underwent PIB from January 2003 to December 2011 at the Great Ormond Street Hospital for Children in London, United Kingdom. Thirty-two male patients (56% aged 1.5-16 years (median: 10.2 at the time of transplantation were included in the study and followed-up for 33 (6-78 months. The results were compared with 33 controls. Results: The PIB showed normal histopathological findings in 13 patients (41%, mild chronic vascular changes in 8 (25%, focal tubular atrophy in one, moderate to severe chronic vascular change in 3, mild to moderate acute tubular damage in 6, and tissue was inadequate in one subject. Delayed graft function (DGF was observed in 3 patients; 2 with vascular changes in PIB, and one with normal histopathological findings. Two subjects with PIB changes lost their grafts. The estimated glomerular filtration rate at 3-, and 6-months post-transplantation was lower in children with abnormal PIB changes compared with those with normal PIB. There was one case of DGF in the control group, and 4 children lost their grafts including the one with DGF. Conclusion: Pre-implantation renal biopsy can provide important baseline information of the graft with implications on subsequent medical treatment for pediatric renal transplant recipients.

    We determined the long-term mortality and renal allograft function of renal transplant recipients admitted to the intensive care unit (ICU). A single institution retrospective observational cohort study of all renal transplant patients admitted to the ICU was performed. Serum creatinine was recorded up to one yr after hospital discharge and survival data were collected for three yr. Chest sepsis was the commonest reason for ICU admission. ICU and hospital mortality were 32% and 19% respectively. Predictors of hospital mortality included the presence of sepsis and duration of mechanical ventilation (MV). Of the patients who were discharged from ICU, three-yr mortality was 50%. Renal function at one yr was worse than that at hospital discharge and at baseline, though not statistically significant. Death-censored allograft loss was 11% over the three-yr follow up period. Sepsis and requirement for MV are independent predictors of mortality in renal transplant recipients admitted to ICU. Renal transplant recipients with chest sepsis may warrant earlier ICU admission. Any loss of renal allograft function during an episode of critical illness appears to have a lasting effect, and longterm patient and allograft survival is poor. © 2011 John Wiley & Sons A/S.

    Full Text Available Left ventricular hypertrophy (LVH is frequently observed in chronic dialysis patients and is also highly prevalent in kidney transplant recipients. This study evaluates the impact of long-functioning hemodialysis vascular access on LVH in single center cohort of kidney transplant recipients. 162 patients at 8.7 ± 1.8 years after kidney transplantation were enrolled. Echocardiography, carotid ultrasound, and assessment of pulse wave velocity were performed. LVH was defined based on left ventricular mass (LVM indexed for body surface area (BSA and height2.7. There were 67 patients with and 95 without patent vascular access. Both study groups were comparable with respect to gender, age, duration of dialysis therapy, and time after transplantation, kidney graft function, and cardiovascular comorbidities. Patients with patent vascular access were characterized by significantly elevated LVM and significantly greater percentage of LVH, based on LVMI/BSA (66.7 versus 48.4%, P=0.02. OR for LVH in patients with patent vascular access was 2.39 (1.19–4.76, P=0.01. Regression analyses confirmed an independent contribution of patent vascular access to higher LVM and increased prevalence of LVH. We concluded that long-lasting patent hemodialysis vascular access after kidney transplantation is associated with the increased prevalence of LVH in kidney transplant recipients.

    The effect of anti-viral therapy (AVT) on kidney function in liver transplant (LT) recipients has not been well described despite known association of hepatitis C virus (HCV) infection with chronic kidney disease (CKD). We compared the incidence of CKD, and end-stage renal disease (ESRD) in 204 LT recipients with HCV based on treatment response to AVT. The median eGFR at baseline (3 months post-LT) was similar in the SVR (n=145) and non-SVR group (n=59) (69±21 vs. 65±33 mL/min/1.73 m2, p=0.268). In the unadjusted Cox proportional regression analysis, the presence of SVR was associated with 88% lower risk of CKD (HR: 0.12; 95% CI: 0.05-0.31), and 86% lower risk of ESRD (OR: 0.14; 95% CI: 0.05-0.35). Similar result was found after adjustment for propensity score, and time-dependent Cox regression analyses. The estimated slopes of eGFR based on a two-stage mixed model of eGFR change revealed patients with SVR had significantly less steep slope than recipients without SVR [-0.60 ml/min/1.73m2/year; 95% CI: -1.50 to +0.30 versus -2.53 ml/min/1.73m2/year; 95% CI: -3.99 to -1.07; p=0.026)]. In LT recipients with chronic HCV infection, achieving SVR significantly lowers the risk of decline in renal function and progression to ESRD independent of the AVT therapy used.

    Delayed graft function (DGF) is defined as the need for dialysis within the first seven days of transplantation. The frequency of DGF has decreased in the last five years compared with the previous 20 years of the kidney transplant program at a Mexican referral hospital. To determine the incidence and risk factors for DGF in the past five years (2009-2013). We analyzed a retrospective cohort of renal transplant recipients from deceased donors at our hospital between March 2009 and May 2013 (Period 2), and compared the results with a previously evaluated cohort (Period 1, between January 1990 and February 2009). During the analyzed period, 78 deceased donor transplants were performed. The frequency of DGF was 9%. Multivariate analysis showed that recipient older age (OR: 1.074419; 95% CI: 1.0009-1.155116; p = 0.05), transoperative amines administration (OR: 7.73; 95% CI: 1.037-57.6; p = 0.046), and hypotension during surgery in the recipient (OR: 11.6; 95% CI: 1.33-100.8; p = 0.026) were risk factors for DGF. The incidence of DGF has significantly decreased in the past five years when compared to the previous 20 years in our hospital.

    Dengue fever is a mosquito-borne viral disease endemic in many tropical and sub-tropical countries. There is only limited data in the literature about dengue fever in renal transplant recipients and patients with chronic kidney disease. This study compares the clinical course of dengue fever and its impact on renal function in renal transplant recipients, patients with chronic kidney disease and patients with normal base line renal function. An observational study was conducted from 1 st May to 31 st July 2017, at a tertiary care centre of South India. A major epidemic of dengue had occurred during the study period. Twelve renal transplant recipients, 22 patients with CKD and 58 patients with normal baseline renal function (control group) admitted with dengue fever were prospectively studied. Nadir WBC count was lowest in renal transplant recipients (2575 + 1187/mm 3 ), [Pdengue fever were different in renal transplant recipients and patients with CKD. Severe worsening of renal function was common in CKD patients. Worsening of renal function in renal transplant recipients was less severe and transient. This article is protected by copyright.

    Full Text Available Loss of hand function after cervical spinal cord injury (SCI impacts heavily on independence. Multiple nerve transfer surgery has been applied successfully after cervical SCI to restore critical arm and hand functions, and the outcome depends on nerve integrity. Nerve integrity is assessed indirectly using muscle strength testing and intramuscular electromyography, but these measures cannot show the manifestation that SCI has on the peripheral nerves. We directly assessed the morphology of nerves biopsied at the time of surgery, from three patients within 18 months post injury. Our objective was to document their morphologic features. Donor nerves included teres minor, posterior axillary, brachialis, extensor carpi radialis brevis and supinator. Recipient nerves included triceps, posterior interosseus (PIN and anterior interosseus nerves (AIN. They were fixed in glutaraldehyde, processed and embedded in Araldite Epon for light microscopy. Eighty percent of nerves showed abnormalities. Most common were myelin thickening and folding, demyelination, inflammation and a reduction of large myelinated axon density. Others were a thickened perineurium, oedematous endoneurium and Renaut bodies. Significantly, very thinly myelinated axons and groups of unmyelinated axons were observed indicating regenerative efforts. Abnormalities exist in both donor and recipient nerves and they differ in appearance and aetiology. The abnormalities observed may be preventable or reversible.

    Production of reactive oxygen species (ROS) and thereby induction of oxidative stress seem to be one of the major mediators of inflammatory adverse outcomes after renal transplantation. p22(phox) is a polymorphic subunit of NAD(P)H-oxidase that is critical for activation and stabilization of the enzyme. This enzyme is involved in the production of superoxide that triggers inflammatory injuries to the kidney. So in this study, the association between donors and recipients' C242T polymorphism of p22(phox) and acute rejection (AR), delayed graft function (DGF), creatinine clearance (CrCl), and blood pressure in renal-allograft recipients was studied. One hundred ninety six donor-recipient pairs were studied. The C242T polymorphism of p22(phox) was determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). According to p22 genotype, the subjects were divided in wild-type (CC) and T allele carriers (CT+TT). Transplantation outcomes were determined using acute rejection and delayed graft function criteria. The mean arterial pressure was also measured monthly after transplantation. There was a significant association between the recipients' p22(phox) polymorphism and DGF occurrence (OR=2.5, CI: 1.2-4.9, p=0.0009). No significant association was detected between donors' p22(phox) polymorphism and AR and DGF events. CrCl during the six months follow-up after transplantation was lower in the patients who received allograft from donors carrying 242T allele (B=-12.8, CI: -22.9-12.8 (-22.9 to -2.6)). Changes in the blood pressure were not different among the patients having different genotypes of p22(phox). These results suggest that the recipients' p22(phox) C242T polymorphism may be a major risk factor for DGF in renal transplantation. Moreover, the donors' 242T allele seems to affect the rate of CrCl in the renal allograft recipients. Copyright © 2014. Published by Elsevier B.V.

    This study aimed to characterize right heart function in heart transplantation (HTx) patients using advanced echocardiographic assessment and simultaneous right heart catheterization (RHC). Comprehensive two-dimensional (2D) and three-dimensional (3D) echocardiographic assessment of right heart function was performed in 105 subjects (64 stable HTx patients and 41 healthy controls). RHC was performed at rest and during semi-supine maximal exercise test. Compared with controls, in conclusion, HTx patients had impaired right ventricle (RV) systolic function in terms of decreased RV-free wall (FW) global longitudinal strain (GLS) (-20 ± 5% vs. -28 ± 5%, P exercise capacity (r = 0.58, P routine right heart function evaluation after HTx.

  14. Exenatide Pretreatment Improved Graft Function in Nonhuman Primate Islet Recipients Compared to Treatment after Transplant Only

    2012-01-01

    Full Text Available The GLP-1 receptor agonist, exenatide, has previously been shown to improve insulin secretion, protect beta cells from apoptosis, and promote beta cell regeneration. We propose that pretreatment with exenatide will promote islet graft survival and improve graft function. Pancreatectomized cynomolgus monkeys underwent islet allotransplantation and were treated with exenatide beginning on day 0 or day −2. A third group of animals was treated with an immunosuppressive regimen while a fourth group remained untreated. Fasting blood glucose (FBG was used to evaluate graft function along with intravenous glucose tolerance tests (IVGTTs performed at study endpoint (day 10 for untreated and posttransplant exenatide or day 90 for pretreatment exenatide and immunosuppression. The average FBG for pre-treated animals day 5 following transplant was 52.7±14.8 mg/dl, compared to 154.3±105.5 mg/dl for animals treated only following transplant, 59.4 mg/dl ±12.1 for animals treated with immunosuppression, and 265.5±172.3 mg/dl for untreated animals. IVGTTs performed at study endpoint showed normal glucose and insulin curves in the pre-treated exenatide and immunosuppression groups only, with beta cell function actually improving after transplant in the pre-treated group. We conclude, therefore, that exenatide pre-treatment can successfully maintain islet graft survival in nonhuman primates.

    Renal grafts have demonstrated capacity to adapt to the recipient. The aim of this study was to assess the growth of renal grafts transplanted to children, during the first year posttransplant. We conducted a 1 year prospective study comparing the growth of renal grafts from children and adults donors transplanted in children, and correlated this growth with graft function. Two groups were studied: (a) group 1-32 children transplanted with pediatric deceased kidneys from donors younger than 16 years and (b) group 2-31 children transplanted with organs from adult living donors. Anthropometric assessment, sonographic measurement of the graft, and serum creatinine at 1 week, 1, 6, and 12 months posttransplantation were performed. Children from group 1 presented an 18% increase in graft volume after the sixth month of transplant, whereas in group 2 grafts presented a 14% reduction in volume, mainly during the first month; the variation in renal diameters was not uniform. Children from group 1 presented a glomerular filtration rate (GFR) increase during the follow-up (46-102 mL/min/1.73 m). After 1 year, GFR and graft volume were similar. Growth of individuals from both groups was comparable. In the short term, pediatric kidneys raise volume and GFR, whereas adult kidneys slightly lower volume and GFR when transplanted in children. Taking our and other studies results into consideration, we can hypothesize that in addition to compensatory hypertrophy, pediatric grafts are likely capable of continued somatic growth.

    Growing evidence in long-term treatment of heart transplant (HTx) recipients indicates effects of high-intensity interval training (HIIT) on several parameters, including oxygen uptake, vascular function and psychological distress. In this study we compare the effect of HIIT vs continued moderate training (CON) on vascular function, biomarkers and health-related quality of life (HRQoL) in HTx recipients. A randomized, controlled crossover trial of stable HTx recipients >12 months after transplantation was done on patients with 12 weeks of HIIT or 12 weeks of CON, followed by a 5-month washout and crossover. Outcomes included endothelial function, arterial stiffness, biomarkers, HRQoL and markers of anxiety and depression. Sixteen HTx recipients (mean age 52 years, 75% male) completed the study. HIIT increased VO(2peak) more than CON (between-group difference, p HIIT patients (p = 0.02) and borderline increased in CON patients (p = 0.07), whereas there was no significant effect of exercise on the mental component. Depression score decreased significantly in HIIT patients (p = 0.04) with no change in CON patients (p = 0.75), whereas anxiety score decreased significantly in both HIIT (p 0.05). Arterial stiffness and biomarkers were not changed, nor did endothelial function change after HIIT (p = 0.08) or CON (p = 0.68). HIIT and CON are both well tolerated and induce similar improvements in physical components of HRQoL and in markers of anxiety. Effects of either training modality on vascular function and biomarkers could not be confirmed. Copyright © 2015 International Society for Heart and Lung Transplantation. Published by Elsevier Inc.

    The renal clearance of endogenous creatinine (CCr), sodium (CNa) and lithium (CLi) was determined before and after a single intravenous bolus of cimetidine in nine renal transplant recipients. The glomerular filtration rate (GFR) was measured with 125I-iothalamate clearance (CTh). The initial CCr...... of sodium decreased throughout the study (p less than 0.05); CLi was unchanged. In conclusion cimetidine, when measured during 1-h clearance periods, interferes with tubular creatinine secretion in the denervated kidney of transplant recipients without affecting the glomerular filtration rate or proximal...

    New immunosuppressive agents are being actively researched to avoid complications of chronic allograft nephropathy (CAN), calcineurin inhibitor (CNI) nephrotoxicity, and posttransplantation cancer. The family of mTOR inhibitors offers a unique immunosuppressive opportunity to avoid CNI toxicity and reduce the incidence of malignancy. Nevertheless, increasing data have demonstrated that sirolimus (SRL), the first mTOR introduced in the treatment of solid organ transplant recipients, induces proteinuria, an adverse event that could produce deterioration of long-term renal function. In this short-term study of patients followed for 1 to 16 months, we examined changes in renal function and proteinuria among renal transplant recipients converted from a CNI-based regimen to an everolimus (EVL)-based one, a recently introduced mTOR inhibitor. Our data showed that renal function can be optimized after conversion to EVL by up to 42% in recipients showing CAN grade 1 or 2, or CNI nephrotoxicity. Importantly, patients who improved their creatinine clearance did not show increased proteinuria measured in a voided specimen as the ratio of urinary protein and creatinine concentration (P/C). These results, if confirmed with long-term follow-up and a larger number of patients, would allow us to consider EVL as a promising agent for maintenance immunosuppressive regimens in kidney transplantation.

    The purpose of this study was to compare LV function and mass quantification derived from cardiac dual-source CT (DSCT) exams with those obtained by MRI in heart transplant recipients. Twelve heart transplant recipients who underwent cardiac DSCT and MRI examination were included. Double-oblique short-axis 8-mm slice thickness images were evaluated. Left ventricular ejection fraction, end-diastolic volume, end-systolic volume, stroke volume, cardiac output and myocardial mass were manually assessed for each patient by two blinded readers. A systematic overestimation of all left ventricular volumes by DSCT when compared with MRI was observed. Mean difference was 16.58±18.61 ml for EDV, 4.94±6.84 ml for ESV, 11.64±13.58 ml for SV and 5.73±1.14 l/min for CO. Slightly lower values for left ventricular ejection fraction with DSCT compared with MRI were observed (mean difference 0.34±3.18%, p=0.754). Correlation between DSCT and MRI for left ventricular mass was excellent (rho = 0.972). Bland and Altman plots and CCC indicated good agreement between DSCT and MRI left ventricular function and mass measurements. The interobserver correlation was good. In conclusion, DSCT accurately estimates left ventricular ejection fraction, volumes and mass in heart transplant recipients. (orig.)

    Full Text Available There is circumstantial evidence that IFNy+ Treg might have clinical relevance in transplantation. IFNy+ Treg express IFNy receptors and are induced by IFNy. In the present study we investigated in kidney transplant recipients with good long-term stable graft function the absolute cell counts of IFNy+ Treg subsets and whether their expression of Foxp3 is stable or transient.Helios expression determined by eight-color-fluorescence flow cytometry and methylation status of the Foxp3 Treg specific demethylation region (TSDR served as indicators for stability of Foxp3 expression. Methylation status was investigated in enriched IFNy+ and IFNy- Treg preparations originating from peripheral blood using high resolution melt analysis. A total of 136 transplant recipients and 52 healthy controls were studied.Proportions of IFNy+ Treg were similar in patients and healthy controls (0.05% and 0.04% of all CD4+ lymphocytes; p = n.s.. Patients also had similar absolute counts of IFNy producing Helios+ and Helios- Treg (p = n.s.. Most of the IFNy+ and IFNy- Treg in transplant recipients had a methylated Foxp3 TSDR, however, there was a sizeable proportion of IFNy+ and IFNy- Treg with demethylated Foxp3 TSDR. Male and female patients showed more frequently methylated IFNy+ and IFNy- Treg than male and female controls (all p<0.05.Kidney transplant recipients with good long-term stable graft function have similar levels of IFNy+ Treg as healthy controls. IFNy+ and IFNy- Treg subsets in patients consist of cells with stable and cells with transient Foxp3 expression; however, patients showed more frequently methylated IFNy+ and IFNy- Treg than controls. The data show increased levels of Treg subsets with stable as well as transient Foxp3 expression in patients with stable allograft acceptance compared to healthy controls.

    There is ample evidence suggesting (e.g., A. Tesser & S. Rosen, 1975) that people are reluctant to transmit bad news. Research on rumors, on the other hand, suggests that people sometimes are less reluctant to transmit bad news. It is argued that differences between the 2 lines of research include the definitiveness of the consequences of the news and the relationship between communicator and recipient. The influence of these 2 factors on news transmission was investigated in 3 experiments. Results showed that bad news with indefinite consequences was transmitted more often than bad news with definite consequences and that both kinds of bad news were transmitted more often if the recipient was a friend rather than a stranger. Differences in feelings of moral responsibility to transmit the news largely accounted for both effects. The 2 factors did not affect the likelihood of good news transmission.

  2. Modern technology to support carers of care recipients with dementia or functional mental illness: promising progress, but a long road ahead.

    There is no doubt that family carers who look after a family member with dementia or with a functional mental illness fulfill an important role, not only for their loved one, but also for the health and aged care systems of the countries they live in. Due to increasing life expectancy, but also improved healthcare the number of family carers supporting older care recipients with functional mental illness or dementia is on the rise. While the carer role often can offer rewarding experiences caregivers are at increased risk of stress, depression, sleep problems, and often experience poor health outcomes with increased morbidity and mortality (Oyebode, 2003). Next to the stressors directly associated with the carer role, they often do not have the time to engage in healthy behavior to protect their physical, mental, and cognitive health (Loi et al., 2014). There is a wealth of literature providing evidence about effective strategies to support carers and the recent Lancet Commission on Dementia prevention, intervention, and care highlighted the importance of exploring how the use of technological innovations could support carers better (Livingston et al., 2017). The use of modern technology in this context can mean a variety of approaches, such as internet-based programs to provide education and skill-building, virtual support to assist with monitoring and managing challenging behavior, online support groups, and the use of assistive or therapeutic technology to improve safety, enable positive activities, and support communication between carer and care recipient, to name just a few (D'Onofrio et al., 2017; Ienca et al., 2017; Livingston et al., 2017). More specifically, telehealth approaches via videoconferences have the potential to better support carers who live in rural or remote regions (O'Connell et al., 2014) or who cannot attend face-to-face support programs for other reasons such as inability to leave the care recipient alone at home, being a multiple carer

    Full Text Available INTRODUCTION: Breast feeding has long term effects on the developing immune system which outlive passive immunization of the neonate. We have investigated the transfer of milk immune cells and examined the result of transfer once the recipients were adult. METHODS: Non-transgenic mouse pups were foster-nursed by green fluorescent protein (GFP transgenic dams for 3 weeks and the fate of GFP+ cells was followed by FACS analysis, immunohistochemistry and RT-PCR for GFP and appropriate immune cell markers. Pups suckled by non-transgenic dams served as controls. RESULTS: Despite a preponderance of B cells and macrophages in the stomach contents of the pups, most cells undergoing trans-epithelial migration derived from the 3-4% of milk cells positive for T lymphocyte markers. These cells homed to the spleen and thymus, with maximal accumulation at 3-4 weeks. By sensitizing dams with an antigen which elicits a T cell-mediated delayed-type-hypersensitivity (DTH response, we determined that nursing by a sensitized dam (compared to a non-sensitized dam amplified a subsequent DTH response in females and yet suppressed one in males. DISCUSSION: These results suggest that clinical evaluation weighing the pros and cons of nursing male versus female children by mothers with genetically-linked hypersensitivity diseases, such as celiac disease and eczema, or those in regions of the world with endemic DTH-eliciting diseases, such as tuberculosis, may be warranted.

    Treg are a heterogenous cell population. In the present study we attempted to identify Treg subsets that might contribute to stable and good long-term graft function. Lymphocyte and Treg subsets were studied in 136 kidney transplant recipients with good long-term graft function and in 52 healthy control individuals using eight-color-fluorescence flow cytometry. Foxp3 TSDR methylation status was investigated in enriched IFNy+ and IFNy- Treg preparations using high resolution melt analysis.

    Full Text Available Introduction. Tacrolimus extended-release formulation enables once-daily use. Although an increasing number of patients have been converted from twice-daily (Tac- BID to once-daily (Tac-QD formulation, the available information regarding the initiation and follow-up of Tac- QD is sparse. In the present study we investigated influence of switch from Tac-BID or cyclosporine to Tac-QD on renal allograf function, proteinuria and protein-creatinine (P/C ratio. Methods. Between October 2012 and October 2014, the switch from Tac-BID or cyclosporine to tacrolimus extended-release formulation was done in 129(38% female, mean age 49 years renal transplant recipients at different time after transplantation. The analysis focused on markers of graft function (GFR, serum creatinine, proteinuria, P/C ratio, liver function (AST, ALT, γGT, alkaline phosphatase and blood glucose. Clinical data were obtained at baseline (before conversion, 1 month (V1, 6 months (V6 and 12 months (V12 after conversion. Results. Both serum creatinine and GFR showed a statistically significant improvement. With GFR, signifycant improvement was observed as early as V1 and it continued to increase throughout the study period up to V12 (all between-visit changes were statistically significant. With serum creatinine, mean levels were numerically decreasing throughout the follow-up period, but a significant improvement occurred at V6 and remained significant at V12 (both vs. V0 values. Proteinuria and P/C ratio did not show any significant change through the observation period. In the majority of patients, the baseline values of AST, ALT, GGT, AlP and glucose were within normal limits and did not change significantly through the observation period. Analysis of tacrolimus C0 showed a significant decrease throughout the follow-up period, at practically all visit. This finding was paralleled by a significant tacrolimus dose decrease from baseline to V6 and V12, as well as by a significant

    It is controversial whether unilateral interruption of the arteria iliaca interna distal end affects penile hemodynamics and erectile function. The purpose of this study was to prospectively evaluate this influence by detecting the blood flow of the penile artery before and after renal transplantation. Thirty-three patients with chronic renal failure (CRF) on maintenance hemodialysis (MHD) received renal transplantation, the grafts revascularized by end-to-end anastomosis to the right internal iliac artery. Six months before and after the surgery, we obtained the IIEF scores of the patients, recorded their penile blood flow on color Doppler ultrasonography and the levels of serum creatinine, hemoglobin and serum cholesterol, and analyzed post-transplantation immunosuppressive medication. The patients ranged in age from 21 to 55 years, of whom 36% had erectile dysfunction (ED) during MHD, and 33% after renal transplantation. A total of 67% of the renal transplant recipients (RTR) complained of unchanged and 15% deteriorated ED, while 18% admitted improved erectile function. The patients showed a significantly stronger sexual desire after the transplantation than before it (6.2 +/- 1.6 vs 8.9 +/- 0.9, P arteria iliaca interna distal end does not affect the erectile function of RTRs.

    Full Text Available Information is lacking concerning concomitant administration of enteric-coated mycophenolate sodium with tacrolimus (EC-MPS+Tac in renal transplant recipients (RTxR. In this 6-month, prospective, open-label, multicenter study, de novo RTxR were randomized (1 : 1 to low-dose (LD or standard-dose (SD Tac with basiliximab, EC-MPS 720 mg bid, and steroids. Primary objective was to compare renal function at 6-month posttransplantation. Secondary objectives were to compare the incidences of biopsy-proven acute rejection (BPAR, graft loss and death, and new-onset diabetes mellitus (NODM. 292 patients (LD n=151, SD n=141 were included. Mean Tac levels were at the low end of the target range in standard-exposure patients (SD, n=141 and exceeded target range in low-exposure patients (LD = 151 throughout the study. There was no significant difference in mean glomerular filtration rate (GFR between treatments (ITT-population: 63.6 versus 61.0 mL/min. Incidence of BPAR was similar (10.6% versus 9.9%. NODM was significantly less frequent in LD Tac (17% versus 31%; P=0.02; other adverse effects (AEs were comparable. EC-MPS+Tac (LD/SD was efficacious and well tolerated with well-preserved renal function. No renal function benefits were demonstrated, possibly related to poor adherence to reduced Tac exposure.

    Renal transplant recipients (RTR) are at risk of decline of graft function and premature mortality, with high blood pressure as an important risk factor for both. To study the association of the Dietary Approach to Stop Hypertension (DASH) diet with these adverse events, we conducted a prospective cohort study of adult RTR. Dietary data were collected using a validated 177-item food frequency questionnaire and an overall DASH-score was obtained. We included 632 stable RTR (mean ± standard deviation age 53.0 ± 12.7 years, 57% men). Mean DASH score was 23.8 ± 4.7. During median follow-up of 5.3 (interquartile range, 4.1-6.0) years, 119 (18.8%) RTR had renal function decline, defined as a combined endpoint of doubling of serum creatinine and death-censored graft failure, and 128 (20.3%) died. In Cox-regression analyses, RTR in the highest tertile of the DASH score had lower risk of both renal function decline (hazard ratio [HR] = 0.57; 95% confidence interval [CI], 0.33-0.96, P = .03) and all-cause mortality (HR = 0.52; 95%CI, 0.32-0.83, P = .006) compared to the lowest tertile, independent of potential confounders. Adherence to a DASH-style diet is associated with lower risk of both renal function decline and all-cause mortality. These results suggest that a healthful diet might benefit long-term outcome in RTR. © 2018 The Authors.

    Current studies suggest that short-term exposure of parathyroid glands to fibroblast growth factor 23 (FGF23) reduces parathyroid hormone secretion. However, patients with chronic kidney disease (CKD) develop secondary hyperparathyroidism despite high levels of serum FGF23, indicating a parathyroid FGF23 'resistance'. Here we analyzed the expression of the FGF23 receptors Klotho and FGF receptor 1 (FGFR1) in 88 hyperplastic parathyroid glands from 31 patients with CKD (including 21 renal allograft recipients), and their regulation in isolated bovine and human hyperplastic parathyroid cells. Glandular expression was variable, yet the Klotho and FGFR1 mRNA levels declined in parallel with the decreasing glomerular filtration rate, significantly decreasing over CKD stages. We found no association between the expression of Klotho, FGFR1, and the proliferation marker Ki67. In vitro treatment of bovine cells with FGF23 or calcium reduced the Klotho level, whereas active vitamin D(3) compounds increased its expression. Phosphate and parathyroid hormone had no effect. Treatment had less impact on Klotho in cultured human cells than in the bovine healthy cell model, whereas FGFR1 expression was induced in the hyperplastic cells. Thus parathyroid Klotho and FGFR1 decrease with declining renal function, possibly because of alterations in mineral metabolism related to the failing kidney. This could explain the observed parathyroid resistance to FGF23 in late CKD.

    We analysed in a carefully phenotyped cohort of paediatric patients the association of serum angiotensin II type 1 receptor antibodies (AT1R-Ab) with specific histological lesions and with graft function and survival in conjunction with overall and complement-binding donor-specific human leucocyte antigen donor-specific antibodies (HLA-DSA). Sera of 62 patients at the time of renal graft biopsy for clinical indication >1 year post-transplant were assessed for AT1R-Ab by enzyme-linked immunosorbent assay (ELISA) and for DSA and C1q-fixing DSA by single-antigen bead technology. Serum AT1R-Ab concentration was significantly higher in antibody-mediated rejection (ABMR) than in T-cell-mediated rejection or control. By receiver operating characteristic (ROC) curve analysis, the optimal AT1R-Ab cut-off value discriminating between patients with features of ABMR and those without was 9.5 U/mL. A total of 6 of 28 patients (21.4%) with ABMR were only positive for AT1R-Ab. Patients with AT1R-Ab and HLA-DSA double positivity had a significantly higher vascular micro-inflammation score than DSA-negative patients. The 5-year graft survival was only 59% in the AT1R-Ab-positive group compared with 87% in the AT1R-Ab-negative group. Patients with AT1R-Ab and HLA-DSA double positivity tended to have a more rapid decline of estimated glomerular filtration rate (eGFR) than patients who were only positive for AT1R-Ab or HLA-DSA. In a multivariate Cox regression model of non-invasive factors, C1q-positive HLA-DSA, eGFR and AT1R-Ab positivity were significantly associated with accelerated graft function decline. Serum AT1R-Ab positivity in the context of an indication biopsy >1 year post-transplant is associated with the histopathology of ABMR and is an independent non-invasive risk factor for adverse graft outcome. © The Author(s) 2018.

    Full Text Available The incidence and outcomes of acute kidney injury (AKI in kidney transplantation are poorly known. Retrospective cohort analysis was performed on the data of all patients (≥3 months after transplantation and ≥16 years of age admitted to the hospital due to medical or surgical complications from 2007 to 2010. We analyzed 458 kidney transplant recipients, 55.2% men, median age 49 (IQR, 36-58 years, median of 12.5 (IQR, 3-35 months after kidney transplantation; admitted to the hospital due to medical or surgical complications. Most of the patients received a kidney from a deceased donor (62.2%, the primary cause for hospital admission was infection (60.7% and 57 (12.4% individuals were diagnosed with acute rejection (AR. The incidence of AKI was 82.3%: 31.9% stage 1, 29.3% stage 2 and 21.2% stage 3. Intensive care unit (ICU admission (OR 8.90, 95% CI: 1.77-44.56 p = 0.008, infection (OR 5.73, 95% CI: 2.61-12.56, p<0.001 and the use of contrast media (OR 9.34, 95% CI: 2.04-42.70, p = 0.004 were the independent risk factors for AKI development. The mortality rate was 2.1% and all patients who died were diagnosed with AKI. Even after the exclusion of AR cases, at the end of 12 months, the individuals with AKI exhibited higher percent changes in creatinine values when compared with individuals without AKI (9.1% vs. -4.3%; p<0.001. According to KDIGO system, we found a high incidence of AKI among the complications of renal transplantation. As in other scenarios, AKI was associated with renal function loss at 1-year after the hospital discharge.

    2016-11-01

    To report epidemiology and characteristics of urinary lithiasis and its management in kidney allograft at the time of organ procurement or after kidney transplantation. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH): urinary lithiasis, stone, kidney transplantation. Publications obtained were selected based on methodology, language, date of publication (last 10 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 58 articles. After reading, 37 were included in the text based on their relevance. Frequency of urinary lithiasis in renal transplant recipient is similar to those observed in the general population. Generally, urinary lithiasis of the graft is asymptomatic because of renal denervation after organ procurement and transplantation. Nevertheless, this situation may be at high risk due to the immunosuppressed state of the recipient with a unique functioning kidney. Most of the time, the diagnosis is incidental during routine post-transplantation follow-up. Management of urolithiasis in renal transplant recipient is similar to that performed in general population. Due to its potential severity in transplanted immunosuppressed patients with a sole kidney, urolithiasis requires expert urological management. Copyright © 2016 Elsevier Masson SAS.

    Given discrepancies between methods for diagnosing hyposplenism, the purpose of this study was to evaluate the effect of the spleen size on the correlation between the methods, and to propose a model for improving the interpretation. Patients with renal allografts were included, in whom the spleen was assessed using Doppler ultrasound, scintiscan, and the presence of Howell-Jolly bodies (HJBs) in peripheral smears. In 35 subjects, scintiscan and HJBs were normal (Group 0); 20 had an abnormal result in both methods (Group 1); 34 had discordant results with HJBs present (Group 2); and 14 had discordant results with decreased spleen uptake (Group 3). There was no association between HJBs and scintiscan. The patients of Groups 1 and 2 had smaller spleens. The patients with smaller spleen had more hematological evidence of hyposplenism and exhibit smaller discrepancies between the methods than patients with larger spleen. The spleen can tip the balance from a normal to impaired function provided that the spleen size is below the critical mass required to maintain splenic function. A mild impairment of phagocytic function and slight dyserythropoiesis along with a small spleen would result in decreased take up of radiocolloid or the appearance of HJBs in blood smears.

    Electrically evoked compound action potential (ECAP) measures of peak amplitude, and amplitude-growth function (AGF) slope have been shown to reflect characteristics of cochlear health (primarily spiral ganglion density) in anesthetized cochlear-implanted guinea pigs. Likewise, the effect of increasing the interphase gap (IPG) in each of these measures also reflects SGN density in the implanted guinea pig. Based on these findings, we hypothesize that suprathreshold ECAP measures, and also how they change as the IPG is increased, have the potential to be clinically applicable in human subjects. However, further work is first needed in order to determine the characteristics of these measures in humans who use cochlear implants. The current study examined across-site patterns of suprathreshold ECAP measures in 10 bilaterally-implanted, adult cochlear implant users. Results showed that both peak amplitude and slope of the AGF varied significantly from electrode to electrode in ear-specific patterns across the subjects' electrode arrays. As expected, increasing the IPG on average increased the peak amplitude and slope. Across ears, there was a significant, negative correlation between the slope of the ECAP AGF and the duration of hearing loss. Across-site patterns of ECAP peak amplitude and AGF slopes were also compared with common ground impedance values and significant correlations were observed in some cases, depending on the subject and condition. The results of this study, coupled with previous studies in animals, suggest that it is feasible to measure the change in suprathreshold ECAP measures as the IPG increases on most electrodes. Further work is needed to investigate the relationship between these measures and cochlear implant outcomes, and determine how these measures might be used when programming a cochlear-implant processor.

    Treatment-related immunosuppression in organ transplant recipients has been linked to increased incidence and risk of progression for several malignancies. Using a population-based cancer cohort, we evaluated whether organ transplantation was associated with worse prognosis in elderly patients with non-small cell lung cancer (NSCLC). Using the Surveillance, Epidemiology, and End Results Registry linked to Medicare claims, we identified 597 patients aged 65 years or older with NSCLC who had received organ transplants (kidney, liver, heart, or lung) before cancer diagnosis. These cases were compared to 114,410 untransplanted NSCLC patients. We compared overall survival (OS) by transplant status using Kaplan-Meier methods and Cox regression. To account for an increased risk of non-lung cancer death (competing risks) in transplant recipients, we used conditional probability function (CPF) analyses. Multiple CPF regression was used to evaluate lung cancer prognosis in organ transplant recipients while adjusting for confounders. Transplant recipients presented with earlier stage lung cancer (P = 0.002) and were more likely to have squamous cell carcinoma (P = 0.02). Cox regression analyses showed that having received a non-lung organ transplant was associated with poorer OS (P transplantation was associated with no difference in prognosis. After accounting for competing risks of death using CPF regression, no differences in cancer-specific survival were noted between non-lung transplant recipients and nontransplant patients. Non-lung solid organ transplant recipients who developed NSCLC had worse OS than nontransplant recipients due to competing risks of death. Lung cancer-specific survival analyses suggest that NSCLC tumor behavior may be similar in these 2 groups.

    Full Text Available Quality of life analysis of kidney graft recipients includes complex assessment of physical, psychological and social status and also certain laboratory and clinical studies. However we suppose that significance of the study might increase considerably if it would be multicenter. The objective of the present publication is to organize such a multicenter study. Obviously, quality of life of recipients with functioning transplanted kidney is undoubtedly of scientific interest and needs further extended studies that might contribute to better interpretation of long-term results after kidney transplantation.

    Full Text Available Introduction. Although the incidence of malignancy has increased after solid organ transplantation, data on lung cancer in this group of patients is scarce. The aim of this study was to determine clinical characteristics and outcome of patients who developed lung cancer after renal transplantation. Methods. Among a cohort of 1658 patients who received a transplant at our institution and were followedup between 1973 and 2014, five patients developed lung cancer. We analyzed risk factors, transplantation characteristics, treatment options and survival. Results. Lung cancer was diagnosed in 5 patients (0.3%. Time to diagnosis after the transplant procedure ranged from 26 to 156 months (mean 115 months. All of them had a smoking history. Tumors were classified as IIB (20%, IIIA (40%, and IV (40%. Histological types included adenocarcinoma (80% and there was one case of sarcomatoid carcinoma (20%. One patient had concomitant thyroid papillary carcinoma. Radiotherapy was applied in 2 patients, 2 underwent chemotherapy (erlotinib and combination of carboplatinum and etopozide in one patient each, and 2 died within one month after the diagnosis from disseminated malignant disease. Patients with stage IIIA survived 14 and 24 months after the diagnosis. The patient with sarcomatoid cancer underwent thoracotomy with a complete resection, lost his graft function and died 7 months after the diagnosis. Conclusion. Lung cancer is relatively rare malignancy in renal transplant recipients, but associated with high mortality. Smoking is a significant risk factor, thus smoking cessation should be promoted among renal transplant recipients, as well as regular screening for lung cancer.

    In patients after heart transplantation, anemia is relatively common and is associated with impaired kidney function, subclinical inflammatory state, and immunosuppressive treatment. Zonulin-prehaptoglibin-2 is newly discovered protein with poorly defined function. Hemoglobin binds haptoglobin, and this stable complex prevents oxidative stress caused by hemoglobin. Zonulin is necessary for integrity of intracellular tight junction in the gut. Taking into consideration iron metabolism, including its absorption in the gut, the aim of this study was to assess zonulin levels in heart transplant recipients and their possible correlations with iron status, immunosuppressive therapy, and kidney function. The study was performed with 80 stable heart transplant recipients and 22 healthy volunteers. Zonulin, iron status, and inflammatory markers were assessed with the use of commercially available kits. Zonulin correlated with intraventricular diameter (r = 0.30; P zonulin and iron status. Zonulin was significantly lower in heart transplant recipients than in healthy volunteers (P zonulin level. Zonulin, despite its effect on the absorption of different nutrients and other substances and hypothethic role in oxidative stress, seems not to play a role in the pathogenesis of anemia in heart transplant recipients. Its physiologic role remains obscure.

  11. Viral Infection in Renal Transplant Recipients

    Jovana Cukuranovic

    2012-01-01

    Full Text Available Viruses are among the most common causes of opportunistic infection after transplantation. The risk for viral infection is a function of the specific virus encountered, the intensity of immune suppression used to prevent graft rejection, and other host factors governing susceptibility. Although cytomegalovirus is the most common opportunistic pathogen seen in transplant recipients, numerous other viruses have also affected outcomes. In some cases, preventive measures such as pretransplant screening, prophylactic antiviral therapy, or posttransplant viral monitoring may limit the impact of these infections. Recent advances in laboratory monitoring and antiviral therapy have improved outcomes. Studies of viral latency, reactivation, and the cellular effects of viral infection will provide clues for future strategies in prevention and treatment of viral infections. This paper will summarize the major viral infections seen following transplant and discuss strategies for prevention and management of these potential pathogens.

    The changes in parathyroid hormone secretion after successful renal transplantation remain to be clearly elucidated. Our study was aimed at identifying the predictors of hyperparathyroidism in renal transplant recipients. A retrospective single center study involving 37 renal transplant recipients, with a follow-up of at least one year, was performed. All transplants were performed using kidneys from living related donors. The average age of study patients was 30+-10 years, with a male-female ratio of 1.31. The mean duration on hemodialysis (HD) prior to transplantation was 25+-18 months. All the grafts but one were functional after a mean follow-up of 41+-21 months. We noted a rapid reduction of the mean parathyroid hormone (iPTH) level from 383+-265 pg/ml before transplantation to 125+-67 pg/ml at one year and 108+-66 pg/ml at two years after transplantation (p=0.01). Bivariate analysis revealed that the level of iPTH obtained during follow-up correlated with the duration on HD (p=0.03), the serum creatinine at 24-months (p=0.013), and to the level of iPTH in the first year post transplantation (P=<0.001). Other clinical or laboratory parameters were not predictive of hyperparathyroidism after kidney transplantation. Liner regression showed that only the serum creatinine at 24-months independently correlated with the level of iPTH at last follow-up (p=0.02). Our study suggests that short duration on HD and a functional graft are the main predictors of correction of hyperparathyroidism after renal transplantation. (author)

    Hepatic encephalopathy (HE) occurs as a result of liver failure and is often considered to be a clinical indication for liver transplantation (LT). An assessment of post-transplantation consciousness level in recipients with HE is crucial, because recovery of consciousness implies reestablishment of transplant liver function and lack of perioperative brain damage. The purpose of this study is to evaluate factors associated with consciousness recovery time after LT in recipients with HE. Out of 633 adult recipients who underwent LT, recipients who exhibited HE at the time of LT were analyzed retrospectively. The time between graft reperfusion and postoperative consciousness recovery was determined, and recipients were divided into 2 groups: group E with recovery of consciousness early (≤48 hours), and group L with recovery of consciousness late (>48 hours). Analyzed variables included recipient sex, age, graft type, Model for End-Stage Liver Disease score, HE history/duration/type/grade, and preoperative laboratory values, including blood ammonia concentration. HE was present at the time of LT in 69 (10.9%) of 633 recipients. Among the 69 recipients, 11 recipients who died or underwent reoperation before consciousness recovery were excluded, and 58 recipients (group E: n = 32; group L: n = 26) were enrolled into analysis. Multivariate analysis showed that HE duration >5 days (odds ratio [OR], 15.58; 95% confidence interval [CI], 1.35-179.56; P = .028) and HE type C (OR, 30.90; 95% CI, 1.67-573.48; P = .021) were the independent factors associated with late recovery from HE after LT. We suggest that recipients with long-duration or type C HE should be carefully managed during the post-transplantation period to prevent deterioration of HE. Copyright © 2014 Elsevier Inc.

    Speech perception is inherently a multisensory process involving integration of auditory and visual cues. Multisensory integration in cochlear implant (CI) recipients is a unique circumstance in that the integration occurs after auditory deprivation and the provision of hearing via the CI. Despite the clear importance of multisensory cues for perception, in general, and for speech intelligibility, specifically, the topic of multisensory perceptual benefits in CI users has only recently begun to emerge as an area of inquiry. We review the research that has been conducted on multisensory integration in CI users to date and suggest a number of areas needing further research. The overall pattern of results indicates that many CI recipients show at least some perceptual gain that can be attributable to multisensory integration. The extent of this gain, however, varies based on a number of factors, including age of implantation and specific task being assessed (e.g., stimulus detection, phoneme perception, word recognition). Although both children and adults with CIs obtain audiovisual benefits for phoneme, word, and sentence stimuli, neither group shows demonstrable gain for suprasegmental feature perception. Additionally, only early-implanted children and the highest performing adults obtain audiovisual integration benefits similar to individuals with normal hearing. Increasing age of implantation in children is associated with poorer gains resultant from audiovisual integration, suggesting a sensitive period in development for the brain networks that subserve these integrative functions, as well as length of auditory experience. This finding highlights the need for early detection of and intervention for hearing loss, not only in terms of auditory perception, but also in terms of the behavioral and perceptual benefits of audiovisual processing. Importantly, patterns of auditory, visual, and audiovisual responses suggest that underlying integrative processes may be

    Older kidney transplant recipients are susceptible to cognitive impairment, frailty, comorbidities, immunosuppression-related complications, and chronic graft failure, however, there has been limited focus on their concerns and expectations related to transplantation. This study aims to describe the perspectives of older kidney transplant recipients about their experience of kidney transplantation, self-management, and treatment goals to inform strategies and interventions that address their specific needs. Face-to-face semistructured interviews were conducted with 30 kidney transplant recipients aged 65-80 years from five renal units in Australia. Transcripts were analyzed thematically. Six themes were identified: restoring vitality of youth (with subthemes of revived mindset for resilience, embracing enjoyment in life, drive for self-actualization); persisting through prolonged recovery (yielding to aging, accepting functional limitations, pushing the limit, enduring treatment responsibilities); imposing sicknesses (combatting devastating comorbidities, painful restrictions, emerging disillusionment, anxieties about accumulating side effects, consuming treatment burden); prioritizing graft survival (privileged with a miracle, negotiating risks for longevity, enacting a moral duty, preserving the last opportunity); confronting health deterioration (vulnerability and helplessness, narrowing focus to immediate concerns, uncertainty of survival); and value of existence (purpose through autonomy, refusing the burden of futile treatment, staying alive by all means). Older kidney transplant recipients felt able to enjoy life and strived to live at their newly re-established potential and capability, which motivated them to protect their graft. However, some felt constrained by slow recuperation and overwhelmed by unexpected comorbidities, medication-related side effects, and health decline. Our findings suggest the need to prepare and support older recipients for self

    The impact of intestinal parasitic infection in renal transplant recipients requires careful consideration in the developing world. However, there have been very few studies addressing this issue in Iran. This study was conducted to determine the prevalence of intestinal parasitic infections in renal transplant recipients in Iran. Stool specimens from renal transplant recipients and control groups were obtained between June 2006 and January 2007. The samples screened for intestinal parasitic infections using direct smear, formalin-ether sedimentation, Sheather's flotation and modified Ziehl-Neelsen staining methods. Out of 150 renal transplant recipients, 33.3% (50), and out of 225 control group, 20% (45) were infected with one or more type of intestinal parasites. The parasites detected among patients included Entamoeba coli (10.6%), Endolimax nana (8.7%), Giardia lamblia (7.4%), Blastocystis spp. (4.7%), Iodamoeba butschlii (0.7%), Chilomastix mesnili (0.7%) and Ascaris lumbricoides (0.7%). Multiple infections were more common among renal transplant recipients group (p < 0.05). This study highlights the importance of testing for intestinal parasites among Iranian renal transplant recipients. Routine examinations of stool samples for parasites would significantly benefit the renal transplant recipients by contributing to reduce severe infections.

    Medication nonadherence is a common problem in renal transplant recipients (RTRs). Mobile health approaches to improve medication adherence are a current trend, and several medication adherence apps are available. However, it is unknown whether RTRs use these technologies and to what extent. In the present study, the mobile technology affinity of RTRs was analyzed. We hypothesized significant age differences in mobile technology affinity and that mobile technology affinity is associated with better cognitive functioning as well as higher educational level. A total of 109 RTRs (63% male) participated in the cross-sectional study, with an overall mean age of 51.8 ± 14.2 years. The study included the Technology Experience Questionnaire (TEQ) for the assessment of mobile technology affinity, a cognitive test battery, and sociodemographic data. Overall, 57.4% of the patients used a smartphone or tablet and almost 45% used apps. The TEQ sum score was 20.9 in a possible range from 6 (no affinity to technology) to 30 (very high affinity). Younger patients had significantly higher scores in mobile technology affinity. The only significant gender difference was found in having fun with using electronic devices: Men enjoyed technology more than women did. Mobile technology affinity was positively associated with cognitive functioning and educational level. Young adult patients might profit most from mobile health approaches. Furthermore, high educational level and normal cognitive functioning promote mobile technology affinity. This should be kept in mind when designing mobile technology health (mHealth) interventions for RTRs. For beneficial mHealth interventions, further research on potential barriers and desired technologic features is necessary to adapt apps to patients' needs. Copyright © 2017 Elsevier Inc.

    A lack of donor hearts remains a major limitation of heart transplantation. Hearts from Centers for Disease Control (CDC) high-risk donors can be utilized with specific recipient consent. However, outcomes of heart transplantation with CDC high-risk donors are not well known. We sought to define outcomes, including posttransplant hepatitis and human immunodeficiency virus (HIV) status, in recipients of CDC high-risk donor hearts at our institution. All heart transplant recipients from August 2010 to December 2014 (n = 74) were reviewed. Comparison of 1) CDC high-risk donor (HRD) versus 2) standard-risk donor (SRD) groups were performed using chi-squared tests for nominal data and Wilcoxon two-sample tests for continuous variables. Survival was estimated with Kaplan-Meier curves. Of 74 heart transplant recipients reviewed, 66 (89%) received a SRD heart and eight (11%) received a CDC HRD heart. We found no significant differences in recipient age, sex, waiting list 1A status, pretransplant left ventricular assist device (LVAD) support, cytomegalovirus (CMV) status, and graft ischemia times (p = NS) between the HRD and SRD groups. All of the eight HRD were seronegative at the time of transplant. Postoperatively, there was no significant difference in rejection rates at six and 12 months posttransplant. Importantly, no HRD recipients acquired hepatitis or HIV. Survival in HRD versus SRD recipients was not significantly different by Kaplan-Meier analysis (log rank p = 0.644) at five years posttransplant. Heart transplants that were seronegative at the time of transplant had similar posttransplant graft function, rejection rates, and five-year posttransplant survival versus recipients of SRD hearts. At our institution, no cases of hepatitis or HIV occurred in HRD recipients in early follow-up. © 2016 Wiley Periodicals, Inc.

  4. Cytomegalovirus Disease Amongst Renal Transplant Recipients in Australia and New Zealand

    2008-01-01

    Full Text Available Cytomegalovirus (CMV is a significant pathogen causing disease in renal transplant patients. The highest incidence of CMV disease occurs during the first 3 months post-transplant and is most problematic in CMV-naïve transplant recipients. In this study, we conducted a retrospective review of two databases, the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA and the National Hospital Morbidity Database, from the Australian Institute of Health and Welfare (AIHW, to examine CMV in renal transplant recipients. The first source looked at CMV serostatus at the time of transplantation and the second recorded hospital admissions for recipients with invasive CMV disease. From the ANZDATA registry, we obtained information from 13,530 renal transplants recipients from 1980 to 2004. Of these recipients, 7808 had a known CMV serostatus, of which 65.7% (5134/7808 had a positive sero antibody status and 34.2% (2674/7808 had a negative sero antibody status. In univariate analysis, factors significantly associated with renal rejection were being male, recipient age <50 years, being diabetic, being diagnosed with cancer at some point and having a positive EBV status. Positive CMV serostatus was not a contributing factor. Between 1993 and 2001 there were 1445 renal transplant recipients hospitalized in Australia with a diagnosis of CMV disease, of which 38% (554/1445 had CMV disease as a principal diagnoses. The average annual rate of admissions with any diagnosis was 3871 episodes per 100,000 people living with a functioning graft. Preventative strategies for CMV in renal transplant recipients should be a priority. New vaccines for CMV may soon be available and renal transplant recipients would be a suitable target group for vaccination.

  6. Training to improve language outcomes in cochlear implant recipients

    Directory of Open Access Journals (Sweden)

    Erin M. Ingvalson

    2013-05-01

    Full Text Available Cochlear implants (CI have brought with them hearing ability for many prelingually deafened children. Advances in CI technology have brought not only hearing ability but speech perception to these same children. Concurrent with the development of speech perception has come spoken language development, bringing with it the hopes that prelingually deafened CI recipient children will develop spoken language capabilities on par with those of normal hearing (NH children. Unfortunately, this has not been the case, and many CI recipient children lag behind their NH peers with large variability in outcomes. It is likely that CI recipient children struggle to develop spoken language at NH-like levels because they have deficits in both auditory and cognitive skills that underlie the development of language. Fortunately, both the auditory and cognitive training literature indicate an improvement of auditory and cognitive functioning following training. It therefore stands to reason that if training improves the auditory and cognitive skills that support language learning, language development itself should also improve. In the present manuscript we will review the auditory and cognitive training and their potential impact on speech outcomes with an emphasis on the speech perception literature.

    Full Text Available To study the effect of immunosuppressive reduction on the incidence and consequence of late acute rejection (LAR in liver allograft recipients, mean daily prednisone dose, mean cyclosporine A (CsA trough and nadir levels were retrospectively reviewed for the nearest 12-week period preceding six episodes of LAR in five liver allograft recipients (group 1. Results were compared with those from a cohort of 12 liver allograft recipients who did not develop LAR (group 2. LAR was defined as acute rejection occurring more than 365 days post-transplantation. Median follow-up for both groups was similar (504 days, range 367 to 1050, versus 511 days, range 365 to 666, not significant. Mean trough CsA levels were lower in patients with LAR compared with those without (224±66 ng/mL versus 233±49 ng/mL but the difference was not statistically significant. In contrast, mean daily prednisone dose (2.5±1.6 mg/ day versus 6.5±2.9 mg/day, P=0.007 and CsA nadir values (129±60 ng/mL versus 186±40 ng/mL, P=0.03 were significantly lower in patients who developed LAR compared with those who did not. Five of six episodes (83% of LAR occurred in patients receiving less than 5 mg/day of prednisone, versus a single LAR episode in only one of 12 patients (8% receiving prednisone 5 mg/day or more (P=0.004. In all but one instance, LAR responded to pulse methylprednisolone without discernible affect on long term graft function. The authors conclude that liver allograft recipients remain vulnerable to acute rejection beyond the first post-transplant year; and reduction of immunosuppressive therapy, particularly prednisone, below a critical, albeit low dose, threshold increases the risk of LAR.

    Full Text Available BACKGROUND Serum paraoxonase is an enzyme synthesised in the liver. It is known to prevent atherosclerosis by inhibiting oxidation of lowdensity lipoprotein. Renal transplant recipients have increased tendency for developing atherosclerosis and cardiovascular disease. Reduced activity of serum paraoxonase contributes to accelerated atherosclerosis and increased cardiovascular complications in these patients. The aim of this study was to estimate serum paraoxonase activity in renal transplant recipients and compare it with healthy controls. MATERIALS AND METHODS 30 renal transplant recipients and 30 age and sex matched healthy controls were taken for the study. Serum paraoxonase activity, blood urea, serum creatinine and uric acid were estimated in these groups. The serum paraoxonase activity was correlated with urea, creatinine and uric acid levels. RESULTS Serum paraoxonase activity was reduced in renal transplant recipients compared to healthy controls. There was a negative correlation between paraoxonase activity and the levels of urea, creatinine and uric acid levels. CONCLUSION In this study, the paraoxonase activity was reduced in renal transplant recipients compared to controls. The increased cardiovascular disease in these patients could be due to reduced paraoxonase activity.

    Solid organ transplant (SOT) recipients are at risk of infections of the central nervous system. However, the incidence and clinical course of bacterial meningitis in SOT recipients are unclear. We studied occurrence, disease course, and prognosis of bacterial meningitis in SOT recipients in the Netherlands. All patients with a medical history of solid organ transplantation were selected from our nationwide prospective cohort study on community-acquired bacterial meningitis in patients >16 years old, performed from March 1, 2006 to October 31, 2014. Data on patient history, symptoms and signs on admission, treatment, and outcome were collected prospectively. For transplant recipients, additional information was collected retrospectively. We identified 6 SOT recipients, all receiving renal transplants. The annual incidence of bacterial meningitis was 7-fold higher (95% confidence interval [CI] 2.94-17.02, P bacterial meningitis (fever, neck stiffness, and change in mental status). Seizures were common, occurring in 33% of patients. Streptococcus pneumoniae and Listeria monocytogenes were identified in 2 patients each, and Escherichia coli and Pseudomonas aeruginosa were both identified once. Four of 6 patients (67%) had an unfavorable functional outcome. Bacterial meningitis is a rare but devastating complication of solid organ transplantation. SOT recipients are at high risk for developing meningitis, and recognition of this condition may be difficult, owing to atypical clinical manifestation. © 2016 The Authors.

    Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population.

    Full Text Available The aim of our study is to determine characteristics and outcomes of kidney cancer in renal transplant recipients. MEDLINE ® database was searched in June 2015 to identify cases of kidney cancer in renal transplant recipients. We include also a new case. Descriptive statistics were used for analysis. Forty-eight (48 recipients reported in 25 papers met the eligibility criteria. The median age was 47 years (range 9-66; 27% were females. Chronic glomerulonephritis, cystic kidney disease and hypertension were common indications for renal transplant. Among donors 24% were females and the median age was 52.5 years (17- 73; 62% of kidney cancers were donor-derived. The median interval between transplant and cancer diagnosis was shorter for cancer of recipient versus donor origin (150 vs. 210 days. Clear cell carcinoma was diagnosed in 17%. 25% had metastasis at diagnosis. Kidney explantation or excision was done in 90% and 84% of cases with and without metastasis respectively. The median survival was 72 months. Actuarial 1-year and 5-year survival rates were 73.4% and 55.1% respectively. Among the recipients from 7 donors who subsequently developed malignancy, 57% were dead within a year. Kidney transplant recipients have a small risk of kidney cancer, which affects younger patients and occurs within a year of transplant, likely due to immunosuppression. Whether the use of older donors may increase the likelihood needs further investigation. The presence of metastasis, explantation or excision of affected kidney and development of cancer in donors predict outcomes. The results may guide patient education and informed decision-making.

    What have we learned so far about the relationship of the recipient's pre-transplant depression and his survival after lung transplantation? First, every chronic disease is always accompanied by somatic changes, functional limitations and emotional, cognitive and social changes as part of the disease. From the first symptoms, to the time of diagnosis of the chronic disease with the expected future, the patient is exposed to the terrible stress of denying and accepting life with a serious chronic illness whose end result is death.

    This study examines student recipients of merit, need-based, service, or minority scholarships, their performance in medical school, and the relationship to future alumni association membership and financial giving. Retrospective data on grade-point average attained across the four-year curriculum and extracurricular activities reported at graduation were collected on students at the University of Kentucky College of Medicine from 1981-1991. Comparisons of academic performance and participation in institutional activities were made across scholarship recipients and non-recipients. These data were then linked to other data tracking alumni association membership and institutional giving. Compared to other scholarship recipients and non-recipients, merit scholars were more likely to be ranked above their class medians and be involved in extracurricular activities, including membership in Alpha Omega Alpha. However, seven years post-graduation, there was no difference between scholarship recipients and non-recipients in alumni association membership or donations to the medical school. Instead, students graduating in the upper half of their class, as compared to graduates in the lower half, and UKCOM graduates who attended the University of Kentucky as undergraduates, rather than students who attended other in-state or out-of state institutions, were more likely to join the medical alumni association. Alumni association members were more likely than non-members to make donations to the institution. More should be done to ensure that graduates who received scholarships are afforded meaningful ways to give back to the institution that supported them as students.

    We report a case of toxic multinodular goiter with severe symptomatic hyperthyroidism in a female diagnosed 5 months after successful renal transplantation. To our knowledge, this is the first well-documented case of hyperthyroidism in a renal transplant recipient that responded well to methimazole. Special attention should be made to the use of methimazole and the possible interaction with immunosuppressive drugs.

    Full Text Available Background:Correction of the uremic state by a functioning allograft often restores fertility in women of reproductive age. The rate of fertility significantly differs between industrial countries, developing and middle east countries.On the other hand the results of pregnancy in Kidney Transplantation (KTP patients are significantly better than hemodialysis patients,and pregnancy most often has no side effects on the function of the transplanted kidney.Objectives: The purpose of this study is to investigate the rate of fertility and results of pregnancy among KTP women, and the assessment of the function of transplanted kidneys during pregnancy among those who have received kidneys in Golestan Hospital from 1996 to 2003. Methods: All the transplanted women in child bearing age who were interested in accepting pregnancy were involved in this study. After pregnancy, all the patients were visited twice a month until the 32nd week of pregnancy and their histories were taken and regular clinical examination and necessary paraclinical assessments were carried out. After the 32nd week, they were visited weekly and other necessary assessments were done in addition to previous measures. Taking immunosuppressive drugs was continued with a minor dose reduction and consumption of harmful drugs like some antihypertensives was prohibited. Results: 16 out of 48 women who were at child bearing age and were interested in pregnancy got pregnant and totally 22 cases of pregnancy occurred. Four cases resulted in spontaneous or therapeutic abortion and 3 out of 18 remaining cases had intrauterine fetal death and the others had successful pregnancy. The most common complication was LBW and following that premature labor. Maternal complications were no more than the general population and the function of the transplanted kidney had no decline in most of the cases. Conclusion:Based on what was mentioned,it is concluded that successful KTP can increase the chance of

    Objectives This study (a) examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of three contrasting types of background music, and (b) compared performance based upon listener groups: CI recipients using conventional long-electrode (LE) devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing (NH) adults. Methods We tested 154 LE CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 NH adults on closed-set recognition of spondees presented in three contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes Signal-to-noise thresholds for speech in music (SRTM) were examined in relation to measures of speech recognition in background noise and multi-talker babble, pitch perception, and music experience. Results SRTM thresholds varied as a function of category of background music, group membership (LE, Hybrid, NH), and age. Thresholds for speech in background music were significantly correlated with measures of pitch perception and speech in background noise thresholds; auditory status was an important predictor. Conclusions Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music. PMID:23342550

    This study sought to elucidate the status of calcium, phosphorus, and parathyroid hormone in patients following kidney transplant. In this cross-sectional study, 20 renal transplant recipients were evaluated. For each patient, age, sex, time since transplant, and body weight were recorded. Inclusion criteria were age > 14 years and good allograft function defined as a serum creatinine level urine calcium, phosphorus, creatinine, and uric acid, as well as concentrations of hemoglobin, serum creatinine, calcium, and phosphorus were measured. To obtain a mean value of serum intact parathyroid hormone in transplant recipients at our center, serum intact parathyroid hormone levels were additionally quantitated in another group of 30 renal transplant recipients. The mean hemoglobin level was 135.6 +/- 17.7 g/L, the mean serum creatinine level was 105.0 +/- 15.3 micromol/L, and the mean serum calcium and phosphorus levels were 2.25 +/- 0.17 mmol/L (normal range, 2.02-2.60 mmol/L) and 1.28 +/- 0.24 mmol/L (normal range, 0.81-1.61 mmol/L), respectively. The mean serum intact parathyroid hormone level was 33.17 +/- 14.67 ng/L (normal range, 10-60 ng/L). Mean 24-hour urine calcium and phosphorus values were 2.32 +/- 1.68 mmol/day (normal, 2.49-6.24 mmol/day) and 19.77 +/- 8.31 mmol/day (normal, 12.91-41.98 mmol/day), respectively. A positive correlation was found between serum calcium and alkaline phosphatase levels (r = +0.71, P = .006). Hemoglobin level was negatively correlated with serum phosphorus level (r = -0.65, P = .003) and sex (r = -0.57, P = .003) and positively correlated with urine creatinine levels (r = +0.69, P = .001). Renal transplant recipients with stable allograft function may have normal serum calcium, phosphorus, and intact parathyroid hormone levels. However, presence of hypocalciuria and elevated serum alkaline phosphatase levels might imply impaired calcium metabolism in these patients.

  10. Usefulness and limitations of transthoracic echocardiography in heart transplantation recipients

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Abstract Transthoracic echocardiography is a primary non-invasive modality for investigation of heart transplant recipients. It is a versatile tool which provides comprehensive information about cardiac structure and function. Echocardiographic examinations can be easily performed at the bedside and serially repeated without any patient's discomfort. This review highlights the usefulness of Doppler echocardiography in the assessment of left ventricular and right ventricular systolic and diastolic function, of left ventricular mass, valvular heart disease, pulmonary arterial hypertension and pericardial effusion in heart transplant recipients. The main experiences performed by either standard Doppler echocardiography and new high-tech ultrasound technologies are summarised, pointing out advantages and limitations of the described techniques in diagnosing acute allograft rejection and cardiac graft vasculopathy. Despite the sustained efforts of echocardiographic technique in predicting the biopsy state, endocardial myocardial biopsies are still regarded as the gold standard for detection of acute allograft rejection. Conversely, stress echocardiography is able to identify accurately cardiac graft vasculopathy and has a recognised prognostic in this clinical setting. A normal stress-echo justifies postponement of invasive studies. Another use of transthoracic echocardiography is the monitorisation and the visualisation of the catheter during the performance of endomyocardial biopsy. Bedside stress echocardiography is even useful to select appropriately heart donors with brain death. The ultrasound monitoring is simple and effective for monitoring a safe performance of biopsy procedures.

    2007-02-01

    The present study documents the school performance of 20 pediatric cochlear implant recipients who attended mainstream classes and compares their educational performance with their normally hearing peers. All 20 school-aged children who underwent cochlear implantation at the Universiti Kebangsaan Malaysia cochlear implant programme participated in this study. Three measures were employed to assess the school performance. First, using the SIFTER teacher-rating scale, the second measure was the child's examination results, and the third was the child's standing compared to his/her peers in language subject, mathematics, and the overall academic performance during the end of semester examinations. The SIFTER rating scale indicated that only 11.8% of the children were identified as not educationally at risk, 17.6% passed four of the SIFTER subtests, whereas the other 71.6% failed in at least two of the subtests on SIFTER. The highest pass rate was obtained in behavior subtest (76.5%), followed by classroom participation (70.6%), attention (58.8%), academic (47.1%), and communication (11.8%). On the educational performance, the cochlear implant recipients performed significantly better in mathematics (mean scores 62.67%; S.D. 22.24) than in language (mean scores 49.96%, S.D. 25.88) (p75th percentile), 18.75% had average performance (25-75th percentile), and another 56.25% performed at below average (mainstream classes varies. Although 43.75% of them thrive well in a full-time mainstream setting, a significant percentage of them (56.25%) performed at below the average level. These findings reemphasize that although a cochlear implant has successfully provided deaf children with a good hearing potential, the majority of its recipients still require additional educational supports in order to function well in the mainstream educational setting.

    End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center. We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

    Clostridium difficile is a bacterial enteric pathogen, which causes clinical disease among solid organ transplant (SOT) recipients. This large, single-center, retrospective study describes incidence, demographics, and impact of C. difficile infection (CDI) among adult SOT recipients, cardiac (n=5), lung (n=14), liver (n=9), renal (n=26), and multiorgan (n=9) patients transplanted and diagnosed with CDI (geneB PCR) between 9/2009 and 12/2012. The overall incidence of CDI in our population during the 40-month period of study was 4%. CDI incidence among cardiac, lung, liver, and renal transplant recipients was 1.9%, 7%, 2.7%, and 3.2%, respectively (P=0.03 between organ-types). Median time from transplant to CDI for all was 51 (14-249) days, with liver recipients having the shortest time to infection, median 36 (15-101) days, and lung recipients having a longer time to infection, median 136 (29-611) days. Antibiotic exposure within 3 months of CDI was evident in 45 of the 63 (71%) patients in this study, 80%, 79%, 100%, 58%, and 67% of cardiac, lung, liver, renal, and multiorgan transplant recipients, respectively. Most patients (83%) were hospitalized within the 3 months preceding CDI. Recipients were followed for a median time of 23 (16-31) months; at the time of last follow-up, 83% of allografts were functioning, and 86% of patients were alive. One death and 1 graft failure were causally related to CDI. CDI had an overall incidence of 4%; clinicians should have heightened awareness for CDI, especially among patients receiving antibiotics, with increased monitoring and aggressive management of CDI.

    Many informal caregivers of dependent midlife and older adults suffer from their own functional limitations. The impact of caregiver functional limitations on care recipient receipt of preventive services is unknown. The purpose of this study is to examine the association between caregiver functional limitations and decreased access to recommended preventive services in dependent care recipients. Dependent adults (those receiving assistance with activities of daily living or instrumental activities of daily living) and their primary informal caregiver were identified from pooled alternate years (2000-2008) of the nationally representative Medical Expenditure Panel Survey (data analyzed February-October 2014). The impact of caregiver limitations (cognitive, mobility, sensory, emotional health) on care recipient's receipt of up to seven different preventive services was assessed via survey-weighted linear and logistic regression. Of the 5-year weighted estimate of 14.2 million caregiver-care recipient dyads, 38.0% of caregivers reported at least one functional limitation. The percentage of recommended preventive services received by care recipients was significantly lower if the caregiver had cognitive, mobility, or emotional health limitations. Each type of caregiver functional limitation was negatively associated with at least four different preventive services. Informal caregivers burdened by their own functional impairments may face challenges in facilitating access to preventive care in dependent midlife and older adults. Policies and interventions designed to prevent or mitigate the impact of caregiver functional impairments are critical to the success of community-based models of care for dependent adults.

    Previous studies have shown that a donor/recipient body weight mismatch affects long-term graft survival and graft function after kidney transplantation. However, the mechanisms are not fully understood. To address the mechanisms, we compared the pathological and physiological features between patients with a donor/recipient body weight mismatch and those without a mismatch 1 yr after kidney transplantation. Furthermore, we investigated the correlation with the donor/recipient body weight ratio. We examined allograft biopsy specimens from 10 recipients with stable kidney function, with body weight mismatch (donor/recipient body weight ratio [D/R BWR] mismatch. We measured glomerular volume (GV) using the Weibel-Gomez method and glomerular density (GD) defined by nonsclerotic glomerular number/renal cortical area as pathological findings. The physiological parameters included estimated glomerular filtration rate and proteinuria (mg/day). These data were evaluated to identify a correlation with D/R BWR. The pathological features showed that GV and GD were identical in the two groups. However, when glomerular enlargement was defined by ΔGV (GV at the 1-yr biopsy minus GV at baseline biopsy), ΔGV was higher in mismatch cases compared with that in cases without a mismatch (10.6 ± 4.6 vs. 5.5 ± 7.1 × 10(5) μm(3) ; P = 0.049). Furthermore, D/R BWR was significantly correlated with ΔGV (P = 0.03, r = -0.436). eGFR values were physiologically identical between the two groups, but the mismatch cases had significantly higher proteinuria levels than that of the cases without a mismatch at 1 yr after kidney transplantation. A donor/recipient body weight mismatch could affect glomerular enlargement and increased proteinuria 1 yr after kidney transplantation. How these two features affect long-term graft survival and function must be addressed in the future. © 2015 Asian Pacific Society of Nephrology.

    Kidney transplantation is the treatment of choice for patients with end-stage kidney disease (ESKD). Rising ESKD prevalence has substantially increased numbers of kidney transplants performed. Maintenance immunosuppression is long-term treatment to prevent acute rejection and deterioration of graft function. Although immunosuppressive treatment using drugs such as calcineurin inhibitors (CNIs, such as cyclosporin A (CsA) or tacrolimus) reduce acute rejection rates, long-term allograft survival rates are not significantly enhanced. CNI-related adverse effects contribute to reduced quality of life among kidney transplant recipients. Adjuvant immunosuppressive therapies that could offer a synergetic immunosuppressive effect, while minimising toxicity and reducing side effects, have been explored recently. Cordyceps sinensis, (Cordyceps) a traditional Chinese medicine, is used as an adjuvant immunosuppressive agent in maintenance treatment for kidney transplantation recipients in China, but there is no consensus about its use as an adjuvant immunosuppressive treatment for kidney transplantation recipients. This review aimed to evaluate the benefits and potential adverse effects of Cordyceps as an adjuvant immunosuppressive treatment for kidney transplant recipients. We searched the Cochrane Kidney and Transplant Specialised Register through contact with the Trials Search Co-ordinator to 7 September 2015 using search terms relevant to this review. We also searched Chinese language databases and other resources. We included all randomised controlled trials (RCTs) and quasi-RCTs evaluating the benefits and potential side effects of Cordyceps sinensis for kidney transplant recipients, irrespective of blinding or publication language. An inclusion criterion was that baseline immunosuppressive therapy must be the same in all study arms. Two authors extracted data. We derived risk ratios (RR) for dichotomous data and mean differences (MD) for continuous data with 95

    Full Text Available Strongyloides stercoralis is an uncommon infection in Saudi Arabia. It can establish latency and cause an autoinfection in humans that lasts for years. The infection can get reactivated during immunosuppression and can result in a life-threatening Strongyloides hyperinfection syndrome. We present three cases of renal transplant recipients who developed Strongyloides infection following transplantation. A bronchoalveolar lavage specimen, a duodenal biopsy and/or a stool specimen from these patients revealed evidence of S. stercoralis larvae. The first two patients received kidneys from the same deceased donor, a native of Bangladesh, an area that is highly endemic for S. stercoralis. The data suggest that the first two cases might be donor derived. High-risk donors and recipients should be screened for Strongyloides infection to initiate treatment before transplantation thus reducing morbidity and mortality.

    An increasing number of cardiac transplants are being carried out around the world. With increasing longevity, these patients present a unique challenge to non-transplant anesthesiologists for a variety of transplant related or incidental surgeries. The general considerations related to a cardiac transplant recipient are the physiological and pharmacological problems of allograft denervation, the side-effects of immunosuppression, the risk of infection and the potential for rejection. A thorough understanding of the physiology of a denervated heart, need for direct vasoactive agents and post-transplant morbidities is essential in anesthetic management of such a patient. Here, we describe a case of a heart transplant recipient who presented for a cholecystectomy at our center.

    Full Text Available Human papillomavirus-driven verruca vulgaris infection is common in solid organ transplant recipients and increases the risk for squamous cell carcinoma. The available treatment modalities have limited response. We report a renal allograft recipient who presented with multiple warts not responding to cryotherapy and radiosurgery with one turning malignant, needing amputation of the finger. An extract from Thuja occidentalis (White cedar tree cured the resistant warts on the other fingers, leaving only superficial scars and without affecting allograft function. We have reviewed the pharmacological and clinical properties of T. occidentalis.

    With expanding experience and success of liver transplantation, increasing numbers of elderly candidates await and undergo liver transplantation. There is accumulating evidence that graft survival and mortality does not appear to differ significantly between the young and carefully selected elderly liver transplantation recipients. Although existing evidence suggests that psychosocial factors impact outcomes after liver transplantation in general, no such information is available specifically for elderly (age ≥65 years) liver transplantation recipients. We conducted a broad medical literature review of outcome studies of elderly liver transplantation recipients. In this review article, we summarize the findings and comment on psychosocial variables included in these studies. Ten outcome studies have reported on the impact of age on the liver transplantation outcomes. There is increasing evidence of favorable outcomes in elderly liver transplantation recipients. Few of these studies include measures of quality of life, functional improvement and other psychosocial variables. Very limited information is available about the impact of psychosocial factors on outcomes in elderly liver transplantation recipients. This dearth of information represents a critical gap in our knowledge and has implications for optimal candidate selection and outcomes after liver transplantation.

    End-stage kidney disease is a life-threatening condition that compels patients to accept either dialysis or transplant. Kidney transplantation is the best choice for patients with end-stage kidney disease because it ensures higher quality of life and longer survival rates than other choices, with less cost for the healthcare system. However, in order for renal recipients to maintain the functioning graft they must take lifelong immunosuppressive medications, with possible side effects and low medication adherence. It is known that low medication adherence in kidney transplant recipients may cause poor outcomes, chronic graft rejection, and graft failure. In this review, the authors give an overview of nonadherence in the transplant setting. In addition, they analyze the role of different technologies as an aid to improve adherence, with a focus on mobile-phone based solutions to monitor and enhance kidney transplant recipient compliance.

    Research indicates that dispositional attachment security fosters empathy, and that short-term increases in security ("security priming") increase empathy and willingness to help others. In two experiments, we examined effects of recalling one's own vulnerability ( feeling hurt by a relationship partner) and security priming on empathy for a recipient in need. In Study 1, the recipient was a middle-aged homeless woman (low similarity to participants); in Study 2, the recipient was a college-aged woman whose boyfriend had been unfaithful (high similarity to participants). In both studies, hurt feelings influenced participants' empathy, but the nature of the influence varied as a function of target-participant similarity. In Study 1, hurt feelings decreased empathy and increased caregiving avoidance. In Study 2, hurt feelings not only increased empathy but also aroused caregiving anxiety. Furthermore, security priming weakened defensive barriers against helping: In Study 1, it reduced caregiving avoidance, and in Study 2, it reduced caregiving anxiety.

    2013-01-01

    Full Text Available Adenoviruses (AdV are emerging pathogens with a prevalence of 11% viruria and 6.5% viremia in kidney transplant recipients. Although AdV infection is common, interstitial nephritis (ADVIN is rare with only 13 biopsy proven cases reported in the literature. We report a case of severe ADVIN with characteristic histological features that includes severe necrotizing granulomatous lesion with widespread tubular basement membrane rupture and hyperchromatic smudgy intranuclear inclusions in the tubular epithelial cells. The patient was asymptomatic at presentation, and the high AdV viral load (quantitative PCR>2,000,000 copies/mL in the urine and 646,642 copies/mL in the serum confirmed the diagnosis. The patient showed excellent response to a combination of immunosuppression reduction, intravenous cidofovir, and immunoglobulin therapy resulting in complete resolution of infection and recovery of allograft function. Awareness of characteristic biopsy findings may help to clinch the diagnosis early which is essential since the disseminated infection is associated with high mortality of 18% in kidney transplant recipients. Cidofovir is considered the agent of choice for AdV infection in immunocompromised despite lack of randomized trials, and the addition of intravenous immunoglobulin may aid in resolution of infection while help prevention of rejection.

    Chikungunya (CHIK) is a mosquito-borne virus (CHIKV) infection that recently appeared in the Americas and thousands of confirmed cases have been reported in Brazil since the first autochthonous cases were reported in September 2014. We reported four cases of CHIK in kidney transplant recipients. The diagnosis was confirmed by positive CHIKV real-time polymerase chain reaction in two cases and positive CHIKV-IgM serology in two patients. The time between transplantation and CHIKV infection ranged from 2 to 11 years. All of them had arthralgia, and 3 of them had fever. Other symptoms were mild conjunctivitis, rash, and retro-orbital pain. Kidney function remained stable in all cases. In three patients prednisone doses were temporally increased and the symptoms disappeared concurrently with the increase of the dose. As for the fourth patient, the prednisone dose remained unchanged and yet she improved. Other immunosuppressive drugs were not changed for the four cases. As far as we know, there are only two previously reported cases of CHIK among solid organ transplant recipients besides the four cases reported here. Despite the small number of cases, we can speculate that the use of immunosuppression might have played a role in the paucity of symptoms and the gradual complete recovery with no complication.

    2010-09-01

    Full Text Available Abstract Background Patients undergoing liver transplantation with preexisting renal dysfunction are prone to further renal impairment with the early postoperative use of Calcineurin-inhibitors. However, there is only little scientific evidence for the safety and efficacy of de novo CNI free "bottom-up" regimens in patients with impaired renal function undergoing liver transplantation. This is a single-center study pilot-study (PATRON07 investigating safety and efficacy of CNI-free, "bottom-up" immunosuppressive (IS strategy in patients undergoing liver transplantation (LT with renal impairment prior to LT. Methods/Design Patients older than 18 years with renal impairment at the time of liver transplantation eGFR 1.5 mg/dL will be included. Patients in will receive a CNI-free combination therapy (basiliximab, MMF, steroids and delayed Sirolimus. Primary endpoint is the incidence of steroid resistant acute rejection within the first 30 days after LT. The study is designed as prospective two-step trial requiring a maximum of 29 patients. In the first step, 9 patients will be included. If 8 or more patients show no signs of biopsy proven steroid resistant rejection, additional 20 patients will be included. If in the second step a total of 27 or more patients reach the primary endpoint the regimen is regarded to be safe and efficient. Discussion If a CNI-free-"bottom-up" IS strategy is safe and effective, this may be an innovative concept in contrast to classic top-down strategies that could improve the patient short and long-time renal function as well as overall complications and survival after LT. The results of PATRON07 may be the basis for a large multicenter RCT investigating the new "bottom-up" immunosuppressive strategy in patients with poor renal function prior to LT. http://www.clinicaltrials.gov-identifier: NCT00604357

    Obesity, in the either kidney donor or the recipient, has been related to worse graft function. The aim of this study was to compare long-term graft outcomes of living-related kidney recipients regarding the donor-to-recipient body mass index (BMI) ratio. From November 2002 to November 2010, 62 consecutive living-related kidney transplantations were performed at our center. Donor and recipient BMIs were categorized by Taiwan's national standard using dividing values of 18.5, 24, and 27 kg/m(2) to divide subjects into donor-to-recipient BMI categories. These with the same BMI category as their donors were defined as the same-BMI group (group 0); recipients with a lower BMI category than their donors were defined as the large-to-small group (group 1); and those with a higher BMI category than their donors were defined as the small-to-large group (group 2). Baseline parameters and posttransplantation follow-up data were analyzed according to this grouping. Of the 57 recipients followed regularly at our hospital (mean follow-up 48.9 months), 21 (36.8.1%) were in group 0; 26 (45.6%) in group 1, and 10 (17.6%) in group 2. The baseline parameters were similar among these groups. The overall graft survival rates were 81.0% in group 0, 76.9% in group 1, and 90.0% in group 2. The rejection-free graft survival rates were 81.0%, 65.4%, and 90.0%, respectively. By Kaplan-Meier analysis, group 1 showed worse rejection-free graft survival than group 0 or group 2 (log-rank P = .046). Living-related recipients of kidneys from donors with a higher BMI showed lower long-term graft survival, which might suggest that petite recipients may need time to compensate adequate blood flow for the relative large graft, thus carrying a higher chance of rejection and worse graft outcomes.

Results. A month later, the level of calcium in the blood to normal, PTH levels decreased by 1,2–3,2 times. A year later, in two patients, blood levels of PTH was back to normal, one − up − 142 pg/ml. Renal excretion of calcium varied differently − in two patients increased gradually, without exceeding the physiological norm, and in one − remained stable. Gene- ral pattern in the dynamics of serum concentration and urinary excretion of phosphorus was not observed. Renal graft function remained stable − GFR 46–76 ml/min. BMD of the distal forearm, femoral neck and lumbar spine in two patients remained the same, in one − increased by 14, 6 and 7%. Adverse events were absent. Conclusion. Application of cinacalcet is promising for the correction of HPT in renal transplant recipients

    Full Text Available Background and Aim. Advanced chronic kidney disease (CKD severely impairs life expectancy and quality of life in affected patients. Considering its benefits, renal transplantation currently represents the optimal treatment solution for end stage kidney disease patients. Pre-transplant assessment aims to maximize the graft and patient survival by identifying potential factors influencing the post-transplant outcome. The aim of this study has been to analyze recipient related prognostic factors bearing an impact on graft survival. Material and Methods. We analyzed the graft outcomes of 426 renal transplantations performed at the Clinical Institute of Urology and Renal Transplantation of Cluj-Napoca, between January 2004 and December 2008. Variables related to recipient and to potential donor/recipient prognostic factors were studied using univariate and multivariate analysis. Results. Graft survivals at 1, 3, 5 and 7 years were 94.01%, 88.37%, 82.51% and 78.10%, respectively. Chronic rejection (41.11% and death with a functioning graft (18.88% were the main causes of graft loss. In uni and multivariate analysis the recipient related variables found to influence the renal graft outcome were: peritoneal dialysis, pre transplant residual diuresis, grade I hypertension, severe iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition. The worst graft outcomes have been found for recipients on peritoneal dialysis, with anuria, hypotension, severe iliac atheromatosis, ischemic heart disease, stroke history, dyslipidemia and a poor nutritional status. Conclusion. The type of dialysis, the pre transplant residual diuresis, recipient arterial blood pressure, iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition significantly influence graft survival.

    Full Text Available Leiomyoma, the benign tumor of smooth muscle cell origin, is commonly seen in genitourinary and gastrointestinal tracts. Primary intracranial leiomyoma, however, is extremely rare occurrence. We hereby report a case of Epstein-Barr negative primary intracranial leiomyoma in a middle-aged renal transplant recipient, which mimicked left frontal parasagittal meningioma on neuroimaging. The tumor was completely excised and diagnosis of leiomyoma was clinched on pathological analysis with immunohistochemistry. The patient improved after tumor removal, and no evidence of tumor recurrence was noted on follow-up study after 10 months postsurgically.

    Large-scale implantable cardioverter defibrillator (ICD) trials have unequivocally shown a reduction in mortality in appropriately selected patients with heart failure and depressed left ventricular function. However, there is a strong association between shocks and increased mortality in ICD recipients. It is unclear if shocks are merely a marker of a more severe cardiovascular disease or directly contribute to the increase in mortality. The aim of this review is to examine the relationship between ICD shocks and mortality, and explore possible mechanisms. Data examining the effect of shocks in the absence of spontaneous arrhythmias as well as studies of non-shock therapy and strategies to reduce shocks are analysed to try and disentangle the shocks versus substrate debate.

    Malaria prophylaxis is usually not provided routinely for most post renal transplant recipients in malaria endemic zones. Therefore, very little information is known about the incidence and severity of this disease among the post-transplant recipients in our environment. Hence a prospective, non-randomized open label clinical trial to determine the incidence of malaria and the beneficial effect of malaria prophylaxis among renal transplant recipients in Nigeria was carried out. All seven consecutive patients who had renal transplants and returned to the unit not more than four weeks later were seen and followed up. This consisted of an initial four week period of no prophylaxis and another four weeks of prophylaxis with proguanil hydrochloride 200 mg daily. Weekly thin and thick blood films by Giemsa stain were examined and other routine investigations of liver function tests, full blood count, urea, creatinine, electrolytes and urinalysis were done. Only three out of the seven patients (42.8%) had positive smears for malaria parasites in the initial no prophylaxis phase. No malaria parasites were detected at the prophylactic phase. There was no significant difference in the results of other investigations including the renal function between the two phases. This study has shown the benefit of short term routine malaria prophylaxis among renal transplant recipients in malaria endemic zones.

    In patients after kidney transplantation, anemia is relatively common and is associated with impaired kidney function, subclinical inflammatory state, and immunosuppressive treatment. Zonulin-prehaptoglobin-2, a newly discovered protein, is necessary for integrity of intracellular tight junctions in the gut. Taking into consideration iron metabolism, including its absorption in the gut, we designed a cross-sectional study to look for the possible interactions among zonulin, iron status, and anemia in kidney transplant recipients. The study was performed on 72 stable kidney transplant recipients and 22 healthy volunteers. Zonulin, iron status, and inflammatory markers were assessed with the use of commercially available kits. Zonulin was significantly lower in kidney allograft recipients than in healthy volunteers (P Zonulin correlated with systolic blood pressure (r = -0.33; P Zonulin was not affected by sex, type of immunosuppressive therapy, presence of diabetes, coronary artery disease, heart failure, hypertension, or cause of end-stage renal disease. Zonulin was not related to any of the iron parameters studied. In multiple regression analysis, predictors of zonulin were total protein and thyroglobulin-binding protein, explaining 46% of variation. Zonulin, with its poorly defined function, does not seem to play a role in the anemia in kidney allograft recipients; however, it seems to be related to the absorption process in the gut.

    Full Text Available The aim of this study was to assess the physical performance (Karnofsky or Lansky's Performance Scale, as well as the social/familial, emotional, functional and cancer treatment by bone marrow transplant (FACT-BMT battery. Subjects were all adolescents (13 to 20 years of age who underwent a transplant at the Bone Marrow Transplant Unit (Serviço de Transplante de Medula Óssea of the University Hospital (Hospital de Clínicas of Universidade Federal do Paraná, (STMO-HC-UFPR in the calendar year (January to December of 1999. The initial sample consisted of thirteen patients (seven male, six female, of whom four had a previous diagnosis of a neoplastic condition and nine of a non-neoplastic condition. Allografts were used in all cases. The study instruments and scales were applied twice: firstly, in the month prior to the procedure and secondly, on the hundredth day afterwards. Three patients died before the second assessment was carried out. Therefore, only 10 patients completed the study and were the subject of the full analysis. Results show that although 4/10 of the patients had an improved physical performance as shown by the Karnofsky and Lansky's Performance Scale, 9/10 reported difficulties to resume day-to-day activities and chores (professional, educational and homework, as shown by the FACT-BMT battery. In other domains assessed, results showed variations between the pre and post procedures but without reaching statistical significance. It could be concluded that the therapeutic intervention in itself may affect the quality of life of the subjects. It has to be said, however, that this study was carried out within the frame of continuous medical treatment and this may have acted as a confounder. Further long-term longitudinal studies are, therefore, required to improve our understanding of these issues.O estudo teve por objetivo analisar o desempenho físico (Escala de Desempenho de Karnofsky ou de Lansky, assim como o desempenho

    Full Text Available Other-regarding preferences are a critical feature of human cooperation but to what extent non-human animals exhibit these preferences is a matter of intense discussion. We tested whether jackdaws show prosocial behaviour (providing benefits to others at no cost to themselves and altruism (providing benefits to others while incurring costs with both sibling and non-sibling recipients. In the prosocial condition, a box was baited on both the actor's and the recipient's side (1/1 option, whereas another box provided food only for the actor (1/0 option. In the altruistic condition, the boxes contained food for either the actor (1/0 option or the recipient (0/1 option. The proportion of selfish (1/0 option and cooperative (1/1 and 0/1 option, respectively actors' choices was significantly affected by the recipients' behaviour. If recipients approached the boxes first and positioned themselves next to the box baited on their side, trying to access the food reward (recipient-first trials, actors were significantly more cooperative than when the actors approached the boxes first and made their choice prior to the recipients' arrival (actor-first trials. Further, in recipient-first trials actors were more cooperative towards recipients of the opposite sex, an effect that was even more pronounced in the altruistic condition. Hence, at no cost to the actors, all recipients could significantly influence the actors' behaviour, whereas at high costs this could be achieved even more so by recipients of different sex. Local/stimulus enhancement is discussed as the most likely cognitive mechanism to account for these effects.

    Full Text Available Renal transplantation is associated with increased incidence of cancer. We reviewed a large series of renal transplant recipients to determine the incidence and outcome of patients with malignant changes located at the head and neck. A total of 1232 renal transplant recipients have been followed at Department of Dialysis University Hospital Centre Zagreb from 1972 to 2009. Demographic data, localization and disease outcome were evaluated in patients who developed cancer. Twenty one patients (1,7% developed 27 head and neck malignancies. The average time from transplantation to development of cancer was 56,8 months. The mean length of follow-up was 9,4±4,8 years. Eighteen malignancies were cutaneous in origin and 9 were noncutaneous. Of cutaneous malignancies, 88.9% were basal cell carcinoma; one patient had Merkell-cell carcinoma and one patient developed squamous cell carcinoma. Six cases of basocellular skin cancer were recorded in one fair-skin patient. Noncutaneous malignancies involved the oral cavity (2 cases of Kaposi’s sarcoma and one pharyngeal cancer and the thyroid gland in 3 patients each. Two patients had post-transplant lymphoproliferative disorder occurring at the head and neck. One patient had brain tumor. Radical surgery, radiation, and/or chemotherapy were necessary in 33,3% of patients. Immunosuppression was reduced in all patients, and 12 patients were switched from the calcineurin-based immunosuppression to sirolimus. They all have stable graft function. None of the patients died from cancer. Immunosuppression was ceased in one patient with Kaposi’s sarcoma who returned to dialysis and died 10 years later from heart failure. An increased incidence of cancer occurring in the head and neck was recorded. Careful skin examination and oral examination is mandatory for discovering cancer before dissemination. Sirolimus is safe alternative to calcineurin-based immunosuppression in patients who developed head and neck

    As we saw last month, over 40% of the students who recently earned bachelor's degrees in physics enter the job market. There are employment opportunities for these graduates in all areas of the economy. When we contact graduates, we ask them where they are working, and we use their responses to compile a list of employers in each state who have recently hired a physics bachelor's degree recipient. We also produce a separate list of firms that have hired three or more physics bachelor's. These lists can be useful tools for students who want to know more about where one can find a job with a bachelor's degree in physics.

    Full Text Available Transplant biopsy has always been the gold standard for assessing the immune response to a kidney allograft (Chandraker A: Diagnostic techniques in the work-up of renal allograft dysfunction—an update. Curr Opin Nephrol Hypertens 8:723–728, 1999. A biopsy is not without risk and is unable to predict rejection and is only diagnostic once rejection has already occurred. However, in the past two decades, we have seen an expansion in assays that can potentially put an end to the “drug level” era, which until now has been one of the few tools available to clinicians for monitoring the immune response. A better understanding of the mechanisms of rejection and tolerance, and technological advances has led to the development of new noninvasive methods to monitor the immune response.

    Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric...

    Agrobacterium tumefaciens is a natural genetic engineer widely used to deliver DNA into various recipients, including plant, yeast and fungal cells. The bacterium can transfer single-stranded DNA molecules (T–DNAs) and bacterial virulence proteins, including VirE2. However, neither the DNA nor the protein molecules have ever been directly visualized after the delivery. In this report, we adopted a split-GFP approach: the small GFP fragment (GFP11) was inserted into VirE2 at a permissive site to create the VirE2-GFP11 fusion, which was expressed in A. tumefaciens; and the large fragment (GFP1–10) was expressed in recipient cells. Upon delivery of VirE2-GFP11 into the recipient cells, GFP fluorescence signals were visualized. VirE2-GFP11 was functional like VirE2; the GFP fusion movement could indicate the trafficking of Agrobacterium-delivered VirE2. As the natural host, all plant cells seen under a microscope received the VirE2 protein in a leaf-infiltration assay; most of VirE2 moved at a speed of 1.3–3.1 μm sec−1 in a nearly linear direction, suggesting an active trafficking process. Inside plant cells, VirE2-GFP formed filamentous structures of different lengths, even in the absence of T-DNA. As a non-natural host recipient, 51% of yeast cells received VirE2, which did not move inside yeast. All plant cells seen under a microscope transiently expressed the Agrobacterium-delivered transgene, but only 0.2% yeast cells expressed the transgene. This indicates that Agrobacterium is a more efficient vector for protein delivery than T-DNA transformation for a non-natural host recipient: VirE2 trafficking is a limiting factor for the genetic transformation of a non-natural host recipient. The split-GFP approach could enable the real-time visualization of VirE2 trafficking inside recipient cells. PMID:24299048

    Ganciclovir-resistant (ganR) cytomegalovirus (CMV) is an emerging and important problem in solid organ transplant (SOT) recipients. Only through direct comparison of ganR- and ganciclovir-sensitive (ganS) CMV infection can risk factors and outcomes attributable specifically to ganciclovir resistance appropriately be determined. We performed a retrospective, case-control (1:3) study of SOT recipients with genotypically confirmed ganR-CMV (n = 37) and ganS-CMV infection (n = 109), matched by donor/recipient CMV serostatus, year and organ transplanted, and clinical manifestation. We used χ2 (categorical) and Mann-Whitney (continuous) tests to determine predisposing factors and morbidity attributable to resistance, and Kaplan-Meier plots to analyze survival differences. The rate of ganR-CMV was 1% (37/3467) overall and 4.1% (32/777) among CMV donor-positive, recipient-negative patients, and was stable over the study period. GanR-CMV was associated with increased prior exposure to ganciclovir (median, 153 vs 91 days, P < .001). Eighteen percent (3/17) of lung transplant recipients with ganR-CMV had received <6 weeks of prior ganciclovir (current guideline-recommended resistance testing threshold), and all non-lung recipients had received ≥90 days (median, 160 [range, 90-284 days]) prior to diagnosis of ganR-CMV. GanR-CMV was associated with higher mortality (11% vs 1%, P = .004), fewer days alive and nonhospitalized (73 vs 81, P = .039), and decreased renal function (42% vs 19%, P = .008) by 3 months after diagnosis. GanR-CMV is associated with longer prior antiviral duration and higher attributable morbidity and mortality than ganS-CMV. Upcoming revised CMV guidelines should incorporate organ transplant-specific thresholds of prior drug exposure to guide rational ganR-CMV testing in SOT recipients. Improved strategies for prevention and treatment of ganR-CMV are warranted. © The Author 2017. Published by Oxford University Press for the Infectious Diseases Society

    Solid organ transplant (SOT) recipients are at greater risk than the general population for complications and mortality from influenza infection. We have conducted a systematic review to assess the management and prevention of influenza infection in SOT recipients. Recommendations are provided about the procurement of organs from donors with influenza infection. We highlight the importance of the possibility of influenza infection in any SOT recipient presenting upper or lower respiratory symptoms, including pneumonia. The importance of early antiviral treatment of SOT recipients with suspected or confirmed influenza infection and the necessity of annual influenza vaccination are emphasized. The microbiological techniques for diagnosis of influenza infection are reviewed. Guidelines for the use of antiviral prophylaxis are provided. Recommendations for household contacts of SOT recipients with influenza infection and health care workers are also included. Antiviral dose adjustment guidelines are presented for cases of impaired renal function and for pediatric populations. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Full Text Available ObjectiveOsteoporosis and fragility fractures represent serious complications for the solid organ transplant population. The recommended osteoporosis therapy for organ recipients involves supplementation with calcium and vitamin D and bisphosphonate administration. However, these options can prove limited for patients with impaired renal function. An alternative therapy option is offered by denosumab, a monoclonal antibody that targets receptor activator of nuclear factor kappa-B ligand.Patients and methodsWe evaluated 63 patients with osteoporosis (23 males and 40 females, age 56.4 ± 13.1 years following solid organ transplantation (15 diabetic patients after simultaneous transplantation of the kidney and pancreas, 34 patients after kidney transplantation, and 14 patients with liver grafts. Osteoporosis was diagnosed according to standard DEXA examination using the Lunar Prodigy apparatus. Transplanted patients with impaired renal function were treated for osteoporosis of the lumbar spine (L-spine and/or proximal femur with calcium and vitamin D supplementation and 60 mg of denosumab every 6 months between the years 2012 and 2017. The mean duration of the therapy was 1.65 ± 0.7 years.ResultsAfter denosumab therapy, L-spine T-scores improved across the whole group, ranging from −2.7 ± 0.09 to −1.8 ± 1.0 (p < 0.001. T-score values for the proximal femur increased from −2.5 ± 0.8 to −2.0 ± 0.7 after the therapy (p < 0.01. We observed only a mild, statistically insignificant improvement in distal forearm T-scores. The mean increase in L-spine bone mineral density (BMD was 11.5 ± 6.2% in subjects with osteoporosis at this site and 10.4 ± 6.1% in the case of all patients. BMD of the proximal femur increased by 10.4 ± 8.3% in patients with osteoporosis and by 7.5 ± 7.3% in all patients. Denosumab therapy decreased the prevalence of osteoporosis in the L-spine from 75 to 27% (p

    Full Text Available Abstract Background Spontaneous Regression/Complete Resistant (SR/CR mice are resistant to cancer through a mechanism that is mediated entirely by leukocytes of innate immunity. Transfer of leukocytes from SR/CR mice can confer cancer resistance in wild-type (WT recipients in both preventative and therapeutic settings. In the current studies, we investigated factors that may impact the efficacy and functionality of SR/CR donor leukocytes in recipients. Results In sex-mismatched transfers, functionality of female donor leukocytes was not affected in male recipients. In contrast, male donor leukocytes were greatly affected in the female recipients. In MHC-mismatches, recipients of different MHC backgrounds, or mice of different strains, showed a greater negative impact on donor leukocytes than sex-mismatches. The negative effects of sex-mismatch and MHC-mismatch on donor leukocytes were additive. Old donor leukocytes performed worse than young donor leukocytes in all settings including in young recipients. Young recipients were not able to revive the declining function of old donor leukocytes. However, the function of young donor leukocytes declined gradually in old recipients, suggesting that an aged environment may contain factors that are deleterious to cellular functions. The irradiation of donor leukocytes prior to transfers had a profound suppressive effect on donor leukocyte functions, possibly as a result of impaired transcription. The cryopreserving of donor leukocytes in liquid nitrogen had no apparent effect on donor leukocyte functions, except for a small loss of cell number after revival from freezing. Conclusion Despite the functional suppression of donor leukocytes in sex- and MHC-mismatched recipients, as well as old recipients, there was a therapeutic time period during the initial few weeks during which donor leukocytes were functional before their eventual rejection or functional decline.

  7. Perceptual learning and auditory training in cochlear implant recipients.

    2007-09-01

    Learning electrically stimulated speech patterns can be a new and difficult experience for cochlear implant (CI) recipients. Recent studies have shown that most implant recipients at least partially adapt to these new patterns via passive, daily-listening experiences. Gradually introducing a speech processor parameter (eg, the degree of spectral mismatch) may provide for more complete and less stressful adaptation. Although the implant device restores hearing sensation and the continued use of the implant provides some degree of adaptation, active auditory rehabilitation may be necessary to maximize the benefit of implantation for CI recipients. Currently, there are scant resources for auditory rehabilitation for adult, postlingually deafened CI recipients. We recently developed a computer-assisted speech-training program to provide the means to conduct auditory rehabilitation at home. The training software targets important acoustic contrasts among speech stimuli, provides auditory and visual feedback, and incorporates progressive training techniques, thereby maintaining recipients' interest during the auditory training exercises. Our recent studies demonstrate the effectiveness of targeted auditory training in improving CI recipients' speech and music perception. Provided with an inexpensive and effective auditory training program, CI recipients may find the motivation and momentum to get the most from the implant device.

    Herein, we describe a case of early belatacept conversion in a human immunodeficiency virus (HIV)-positive kidney transplant recipient in an effort to improve suboptimal graft function and avoid drug interactions following anti-thymocyte globulin (ATG) administration. We observed improvement in renal function without HIV disease progression or opportunistic infections. Donor-specific antibodies appeared shortly after conversion but cleared without intervention. This case highlights belatacept as a means to improve renal function and avoid significant drug interactions even following ATG induction. © 2017 John Wiley & Sons A/S.

    Ventricular assist devices (VADs) have been associated with high rates of neurologic injury in pediatric patients during the period of support, but the delayed consequences of this type of injury have not been described in the literature. In this study we assess cognitive outcomes with indices of general intellectual functioning, including working memory, processing speed, perceptual reasoning and verbal comprehension, for pediatric heart transplant recipients who required VAD support as a bridge to transplant (n = 9). We present an aggregate of these VAD patients combined with heart transplant recipients who did not require mechanical circulatory support (n = 11), and compare the performance of all transplant patients (n = 20) to typically developing, healthy comparators (n = 12). We also present a post hoc analysis of those transplant recipients with significant medical morbidity in the first year of life, referred to as the "high-risk" transplant group (n = 5), and compare them with the "low-risk" transplant group (n = 15) and the typically developing comparators (n = 12). The mean performance of the VAD patients was in the average range for each of the examined indices of cognitive functioning. A total of 11% of the VAD patients performed in the impaired range and 78% performed in the average range, with 11% in the superior range on measures of general intellectual functioning. The typically developing participants performed significantly better than the aggregated transplant recipients on all indices except verbal comprehension. Lower cognitive performance in the combined transplant group appears to be associated with medical morbidity in the first year of life. Despite significant neurologic risk factors, this cohort of pediatric patients who were bridged to transplant with VAD demonstrated resiliency in terms of cognitive outcomes. In this heterogeneous population, it is likely that multiple factors contributed to the cognitive outcomes. As VAD use becomes

    Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

  11. Prostate cancer in renal transplant recipients

    Directory of Open Access Journals (Sweden)

    Benjamin A. Sherer

    Full Text Available ABSTRACT As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs being diagnosed with prostate cancer (CaP is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients. To better understand the unique characteristics of CaP in the renal transplant population, we performed a literature review of PubMed, without date limitations, using a combination of search terms including prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen kinetics, immuno-suppression, prostatectomy, and radiation therapy. Of special note, teams facilitating the care of these complex patients must carefully and meticulously consider the altered anatomy for surgical and radiotherapeutic planning. Active surveillance, though gaining popularity in the general low risk prostate cancer population, needs further study in this group, as does the management of advance disease. This review provides a comprehensive and contemporary understanding of the incidence, screening measures, risk stratification, and treatment options for CaP in RTRs.

    Few studies have examined the impact of patient weight on heart transplant (HT) outcomes. Nine outcomes were compared in 2 groups of HT recipients (N = 347) based on their mean body mass index (BMI) during the first 3 years post-HT. Group 1 consisted of 108 non-overweight patients (BMI <25; mean age 52; 29.6% females; 16.7% minorities). Group 2 consisted of 239 overweight patients (BMI ≥25; mean age 52; 15.9% females; 13.8% minorities). Outcomes were: survival, re-hospitalization, rejections, infections, cardiac allograft vasculopathy (CAV), stroke, renal dysfunction, diabetes, and lymphoma. Non-overweight patients had shorter survival, were re-hospitalized more days after the HT discharge, and had more lymphoma and severe renal dysfunction. Overweight patients had more CAV, steroid-induced diabetes, and acute rejections. Overweight HT patients had better survival, but more rejections, CAV, and diabetes. Non-overweight HT patients had worse survival, plus more re-hospitalization time, lymphoma, and renal dysfunction. Copyright © 2016 Elsevier Inc. All rights reserved.

    2016-08-01

    Transplantation of the blood group A2B in a recipient was successfully performed in the setting of receiving a deceased donor kidney from an "incompatible" A1B donor. The donor and recipient were both typed for ABO blood group, including ABO genotyping. The donor and recipient were tested for ABO, non-ABO, and human leukocyte antigen (HLA) antibodies. The donor and recipient were typed for HLA antigens, including T- and B-flow cytometry crossmatch tests. The recipient's RBCs were negative with A1 lectin, and immunoglobulin G anti-A1 was demonstrated in the recipient's plasma. The donor-recipient pair was a four-antigen HLA mismatch, but final T- and B-flow cytometry crossmatch tests were compatible. The transplant procedure was uneventful; the patient experienced immediate graft function with no episodes of rejection or readmissions more than 2 years later. It may be safe to transplant across the A1/A2 blood group AB mismatch barrier in the setting of low titer anti-A1 isoagglutinins without the need for pretransplant desensitization even if the antibody produced reacts with anti-human globulin. © American Society for Clinical Pathology, 2016.

    There are high levels of turnover among home care workers. The study goal was to examine factors connected with job satisfaction of home care workers who resigned from their jobs. A survey (self-administered questionnaire) was conducted of 197 home care workers who resigned from their jobs with a home care agency in Jerusalem. Overall job satisfaction of the home care workers was low to moderate. Memory impairment of the care recipient and quality of the relationship between the care worker and the care recipient were significant in explaining overall and intrinsic job satisfaction of the workers. Functional status (activities of daily living) and the impact of the care recipient's cognitive status on the care worker were significant in explaining job benefit satisfaction. Home care workers who provide care to severely disabled and cognitively impaired older persons experience great work stress. They need ongoing support and training as well as better job benefits.

    This study was conducted to analyze the clinical characteristics and outcome of measles in pediatric liver transplant recipients. This study includes a retrospective data analysis of five pediatric liver transplant recipients with measles who were treated at the Liver Transplant Section, Beijing Friendship Hospital, China, from March to April 2014. The clinical manifestations of measles in pediatric liver transplant recipients were serious. There were three cases complicated with pneumonia, and one with laryngitis. Two cases presented with severe measles pneumonia that developed into severe respiratory failure requiring mechanical ventilation. Four patients recovered after treatment and one patient died of respiratory failure. Pediatric liver transplant recipients with measles are at high risk of severe pneumonia. Measles pneumonitis is frequently fatal to immunocompromised pediatric patients. Treatment should be initiated as soon as possible. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Surgical stress, liberation of cytokines associated with re-perfusion injury, and long standing use of immune suppressive medications in children recipients of orthotopic living related liver transplantation (OLRLT pose cardiovascular risk. Reported cardiovascular adverse effects vary from left ventricular wall thickening, hypertrophic cardiomyopathy to resting ECG abnormalities, asymptomatic ST depression following increased heart rate and ventricular arrhythmias. Twenty-five consecutive children recipients of OLRLT were assessed by conventional 2-D, M-mode echocardiography and Doppler. The mean age ± SD at transplantation and at enrollment in study was 6.3 ± 4.5 and 13.5 ± 5.6 years respectively. All children were on immunosuppressive medications, with tacrolimus being constant among all. Long-term post-transplant echocardiography revealed statistically significant interventricular septal hypertrophy among all (mean thickness 0.89 ± 0.16 cm, (P = 0.0001 in comparison to reference range for age, 24 had pulmonary hypertension (mean mPAP 36.43 ± 5.60 mm Hg, P = 0.0001, and early diastolic dysfunction with a mean Tei index of 0.40 ± 0.10. However cardiac function was generally preserved. Children recipients of OLRLT have cardiac structural and functional abnormalities that can be asymptomatic. Pulmonary hypertension, increased cardiac mass, de novo aortic stenosis and diastolic heart failure were among abnormalities encountered in the studied population. Echocardiography is indispensible in follow-up of children recipients of OLRLT.

    In the present study, clinical criteria used by Spanish nephrologists when approaching chronic kidney disease (CKD) in kidney recipients, as well as their level of maintenance and control of renal function, were evaluated. An epidemiological, observational, multicenter, nation-wide, prospective study was carried out, with a 6-month follow-up period. Three hundred and sixty-eight adult patients with stage3 kidney disease after a 24-month or longer post-transplantation follow-up period were included. Visits schedule included a retrospective visit, a baseline visit, an optional mid-term visit, and a final visit at month6. Mean time since kidney transplantation was 8.2±5.4years. Most common pre-transplant cardiovascular risk factors were high blood pressure (80.2%), followed by high cholesterol levels (61.7%). Serum creatinine levels showed a statistically significant decrease from baseline visit to 6-month visit (0.06±0.22; P<.0001), and glomerular filtration rate (GFR) reduction was -1.03±6.14 (P=0.0014). Significant independent prognostic factors for GFR worsening were: higher 24-hour proteinuria (OR=1.001 per mg; P=.020), longer time since transplantation (OR=1.009 per month; P=.017), and lower hemoglobin levels (OR=1.261 per g/dl; P=.038). Donor age also had some negative influence (OR=1.021 per year; P=.106). Biopsies were obtained in only 8% of kidney transplant recipients with stage 3 CKD with an intervention being carried out in 25.4% of cases. Secondary markers and factors resulting in CKD progression, particularly anemia, are still frequently uncontrolled after kidney transplantation. Only about 2% of patients benefit from a therapeutic intervention based on a biopsy. Clinical perception differs from objective measures, which results in an obvious clinical inertia regarding risk factor control in such patients. Copyright © 2015 The Authors.

    Seborrheic dermatitis is an inflammatory dermatosis with a prevalence of 1-3% in the general population. It is recognized more commonly in those infected by human immunodeficiency virus (HIV). No studies have looked at Seborrheic dermatitis in the context of immunosuppression secondary to organ transplantation. Therefore, we investigated the prevalence of Seborrheic dermatitis in a renal transplant population and characteristics of those affected. A prospective study of 308 renal transplant recipients (RTRs) was carried out. All participants were examined for Seborrheic dermatitis. Descriptive statistics were employed and associations with Seborrheic dermatitis were examined using Fisher's exact test to calculate P-exact values, and Student's t-test was used to compare mean ages and time since transplantation. Statistical analysis was carried out using SPSS version 14.0 for Windows. Seborrheic dermatitis was identified in 29/308 (9.5%) patients and was more common in males (P-exact = 0.004) and in those who had been transplanted for longer (P = 0.02). The disease was mild-moderate severity in the majority but an unusual flexural appearance was recorded in 7/29 patients. Seborrheic dermatitis was less likely in those taking prednisolone (P-exact = 0.006) or tacrolimus (P-exact = 0.008). Seborrheic dermatitis was significantly associated with cutaneous malignancy, in particular squamous cell carcinoma (P-exact Seborrheic dermatitis is more common than other inflammatory dermatoses in immunosuppressed RTRs, but is not as frequent as in those immunosuppressed secondary to HIV. Degree and duration of exposure to immunosuppression and increased colonization with Malassezia yeast genus are likely be important in the aetiology of Seborrheic dermatitis in RTRs. Further studies are required to clarify this.

    Kidney transplantation in recipients with a previous malignancy is often deferred 2 to 5 years after cancer treatment due to fear of cancer recurrence. In Norway, the required waiting period has been 1 year. We compared patient and graft survival of recipients with pretransplant cancer to the outcomes of matched recipients without such cancer (comparators) using Cox regression. From 1963 to 2010, 377 (6.4%) of 5867 recipients had a pretransplant cancer. During a median follow-up of 6.8 years, 256 recipients died, 35 (13.7%) from recurrent cancer and 27 (10.5%) from de novo cancer. Uncensored and death-censored graft loss occurred in 263 and 46 recipients, respectively. All-cause mortality was similar as in comparators (hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.93-1.20]; P = 0.40), death-censored graft loss was lower (HR, 0.63; 95% CI, 0.47-0.84; P = 0.002), and uncensored graft loss was similar (HR, 0.99; 95% CI, 0.87-1.12; P = 0.87). Cancer mortality was higher than in comparators (HR, 1.97; 95% CI, 1.51-2.56; P cancer mortality or all-cause mortality (both P > 0.45). Results were similar within cancer subgroups, with most data in patients with a history of kidney cancer, prostate cancer, urothelial cancer, and skin squamous cell carcinoma. Kidney transplant recipients with a pretransplant cancer had a similar overall patient and graft survival as recipients without such cancer. Cancer mortality was increased, particularly during the first 5 years after transplantation. A short waiting period was not associated with mortality.

    What do ovum donation (OD) recipients request most from their ideal donor: beauty, brains, health or physical self-resemblance? Previous data have shown recipients primarily requested "similar appearance or gene pool." We consider the possibility that these criteria may have changed due to a positive social shift towards OD participation and have evaluated recipients' requests for donor criteria over a span of 5 years. Donor trait preferences of OD recipients (n=438) enrolled in a private, academic OD program from 2008-2012 were assessed in this retrospective cohort analysis. Requests were categorized by appearance, ethnicity, intellect, ability, and mental health. Statistical analyses were conducted by Cochran-Armitage trend tests with significance at pappears that the current recipient is more likely to request a donor with practical traits that would serve their offspring overall quality of life rather than self-reflective traits such as physical resemblance or their genetic composition. We believe that improved awareness and acceptance of OD as a treatment of infertility will continue to inform practical considerations and approaches toward donor recruitment and the donor-recipient matching process.

    We performed single-photon emission computed tomography (SPECT) to investigate the influence of renal transplantation on cerebral blood flow (CBF). Fifteen renal transplant recipients and twelve normal subjects underwent cerebral SPECT with N-isopropyl-p-[ 123 I] iodoamphetamine ( 123 I-IMP). All transplant recipients received prednisolone and cyclosporine (CyA). Regional CBF (rCBF) was measured by defining regions of interest in the cerebral cortex, deep white matter, striatum, thalamus, and cerebellum. In transplant recipients, correlations to the mean overall cortical CBF were assessed using the interval from transplantation to measurement of SPECT, as well as the serum creatinine concentration. Moreover, to investigate the influence of CyA on CBF, the correlation between mean overall cortical CBF and CyA trough concentrations was assessed. In all regions, CBF in renal transplant recipients was significantly lower than in normal subjects. No significant correlation was seen between serum creatinine, interval from transplantation, or CyA trough concentrations and mean overall cortical CBF. Renal transplant recipients demonstrated a decrease in CBF, that can have an associated secondary pathology. Therefore, renal transplant recipients may benefit from post-operative MRI or CT.

    Humans have a remarkable capacity for tuning their communicative behaviors to different addressees, a phenomenon also known as recipient design. It remains unclear how this tuning of communicative behavior is implemented during live human interactions. Classical theories of communication postulate that recipient design involves perspective taking, i.e., the communicator selects her behavior based on her hypotheses about beliefs and knowledge of the recipient. More recently, researchers have argued that perspective taking is computationally too costly to be a plausible mechanism in everyday human communication. These researchers propose that computationally simple mechanisms, or heuristics, are exploited to perform recipient design. Such heuristics may be able to adapt communicative behavior to an addressee with no consideration for the addressee's beliefs and knowledge. To test whether the simpler of the two mechanisms is sufficient for explaining the "how" of recipient design we studied communicators' behaviors in the context of a non-verbal communicative task (the Tacit Communication Game, TCG). We found that the specificity of the observed trial-by-trial adjustments made by communicators is parsimoniously explained by perspective taking, but not by simple heuristics. This finding is important as it suggests that humans do have a computationally efficient way of taking beliefs and knowledge of a recipient into account.

  9. Physical Activity in Kidney Transplant Recipients: A Review.

    2018-02-23

    Physical activity has known health benefits and is associated with reduced cardiovascular risk in the general population. Relatively few data are available for physical activity in kidney transplant recipients. Compared to the general population, physical activity levels are lower overall in kidney recipients, although somewhat higher compared to the dialysis population. Recipient comorbid condition, psychosocial and socioeconomic factors, and long-term immunosuppression use negatively affect physical activity. Physical inactivity in kidney recipients may be associated with reduced quality of life, as well as increased mortality. Interventions such as exercise training appear to be safe in kidney transplant recipients and are associated with improved quality of life and exercise capacity. Additional studies are required to evaluate long-term effects on cardiovascular risk factors and ultimately cardiovascular disease outcomes and patient survival. Currently available data are characterized by wide variability in the interventions and outcome measures investigated in studies, as well as use of small sample-sized cohorts. These limitations highlight the need for larger studies using objective and standardized measures of physical activity and physical fitness in kidney transplant recipients.

  12. Cytomegalovirus disease in a renal transplant recipient: the importance of pre-transplant screening of the donor and recipient

    2013-01-01

    Full Text Available A 16-year-old female patient who was born with a single kidney developed chronic kidney disease during her early childhood due to reflux nephropathy and recurrent urinary tract infection. She progressed to end-stage renal disease (ESRD and was commenced on renal replacement therapy in the form of peritoneal dialysis in May 2011. Subsequently, she underwent living unrelated donor kidney transplantation in China. She was hospitalized soon after returning to Saudi Arabia for management of high-grade fever, shortness of breath, and deterioration of renal function, which was found to be due to cytomegalovirus (CMV disease, proved by kidney biopsy and presence of high level of anti-CMV immunoglobulins. Allograft biopsy showed mature viral particles sized between 120 and 149 nm in the nuclei of the glomerular endothelial cells. The patient was treated with valgancyclovir and specific CMV immunoglobulin, as well as by reducing and even stopping the dose of tacrolimus and mycophenolate. Despite all these measures, her condition continued to deteriorate and she finally died. Our study emphasizes that unrelated renal transplantation, especially if unplanned and improperly prepared, is a very risky procedure that might transfer dangerous diseases and increase the morbidity and mortality of the patients. We strongly stress the need for mandatory and proper screening for CMV carrier status among donors as well as recipients prior to transplantation. Also, a recommendation is made to reject CMV-positive donors.

    Routine microbiologic surveillance is a method of infection control, but its clinical significance in transplant recipients is not known. We analyzed microbiologic data to evaluate the influence of cultured microorganisms between the point of surveillance and infectious episodes in liver transplant recipients. We performed surveillance culture for sputum and peritoneal fluid in liver transplant recipients from January 2009 to December 2011, at the time of transplantation (T1), 5 days (T2), and 10 days (T3) postoperatively. Of the 179 recipients, 32.9% had a positive sputum culture result and 37.4% had a positive peritoneal culture result during surveillance. In the culture surveillance of sputum, 37 organisms were isolated from 35 recipients at T1, and the most common organism was Staphylococcus aureus (n = 13). At T2, 45 organisms were isolated from 39 recipients, including Klebsiella pneumoniae (n = 10), S aureus (n = 8), and Acinetobacter baumannii (n = 6). At T3, 18 organisms were isolated from 15 patients, including Stenotrophomonas maltophilia (n = 5) and K pneumonia (n = 4). In the peritoneal fluid, 11 organisms were isolated from 10 recipients at T1, including Pseudomonas aeruginosa (n = 2) and Enterococcus species (n = 2). At T2, 39 organisms were isolated from 36 recipients, including coagulase-negative Staphylococcus species (CNS; n = 8) and Enterococcus species (n = 7). At T3, 54 organisms were isolated from 51 recipients, including CNS (n = 17) and Candida species (n = 8). Among the 59 patients with positive culture results for sputum surveillance, 16.9% developed pneumonia caused by the same organisms. Among the 67 patients with positive peritoneal fluid culture, 16.4% developed an intra-abdominal infection caused by the same organisms cultured. The recipients with positive surveillance culture had a higher risk of pneumonia (20.3% [12/59] vs 1.6% [2/120]; P < .001) and intra-abdominal infection (31.3% [21/67] vs 18.7% [21/112]; P

    Heart transplant recipients are at risk for developing left ventricular (LV) dysfunction. While traditional echocardiographic parameters have limitations, speckle tracking echocardiography (STE) is a novel technique shown to be more sensitive and accurate in adult studies for evaluating ventricular systolic and diastolic function. Pediatric heart transplant recipients undergoing routine cardiac catheterization were included. Ratio of mitral early diastolic velocity-to-strain rate during early LV filling (E/SR(E)) and global longitudinal peak systolic strain (GLPSS) was measured by STE imaging. These were compared with wedge pressures by catheterization and traditional echocardiographic parameters. A total of 50 subjects (46% males) were included. Mean age of the subjects was 13.0 ± 6.3 years and time since transplant was 4.1 years (range 0.2-17.1 years). While peak mitral inflow to late diastolic velocity (E/A ratio) was the only traditional diastolic function parameter having significant correlation with pulmonary capillary wedge pressure (PCWP) (r = 0.3; P = .3), STE-derived E/SR(E) had modest correlation with PCWP (r = 0.55; P -18%. Interestingly, subjects with coronary artery disease (n = 6) had significantly higher E/SR(E) (71.9 ± 28.4) compared to subjects without (45.2 ± 10.8; P < .001). Diastolic function parameters by STE imaging correlate better with gold standard PCWP measurement than traditional echocardiographic parameters. Also, utilizing STE, abnormalities of longitudinal LV systolic function may be more common than previously thought in pediatric heart transplant recipients without acute graft rejection, despite "normal" systolic function by traditional echocardiogram. © 2015 Wiley Periodicals, Inc.

    While laparoscopic donor nephrectomy has encouraged living kidney donation, debate exists about the safest laparoscopic technique. We compared purely laparoscopic and hand assisted laparoscopic donor nephrectomies in terms of donor outcome, early graft function and long-term graft outcome. We reviewed the records of consecutive laparoscopic and hand assisted laparoscopic donor nephrectomies performed by a single surgeon from 2002 to 2011. Donor operative time and perioperative morbidity were compared. Early graft function for kidneys procured by each technique was evaluated by rates of delayed graft function, need for dialysis and recipient discharge creatinine. Long-term outcomes were evaluated by graft function. A total of 152 laparoscopic donor nephrectomies were compared with 116 hand assisted laparoscopic donor nephrectomies. Hand assisted procedures were more often done for the right kidney (41.1% vs 17.1%, p recipient outcomes were also similar. Delayed function occurred after 0% hand assisted vs 0.9% purely laparoscopic nephrectomies, dialysis was required in 0.9% vs 1.7% and rejection episodes developed in 9.7% vs 18.4% (p >0.05). At last followup the organ was nonfunctioning in 6.1% of hand assisted and 7.7% of purely laparoscopic cases (p >0.05). The recipient glomerular filtration rate at discharge home was similar in the 2 groups. Hand assisted laparoscopic donor nephrectomy had shorter warm ischemia time but perioperative donor morbidity and graft outcome were comparable. The choice of technique should be based on patient and surgeon preference. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

The most common reasons for conversion were nephrotoxicity (30%), chronic allograft vasculopathy (20%) and neoplasms (17%). The doses and mean levels of EVL at baseline (conversion to EVL) and after one year were 1.3 ± 0.3 and 1.2 ± 0.6 mg/d and 6.4 ± 3.4 and 5.6 ± 2.5 ng/mL, respectively. The percentage of patients receiving calcineurin inhibitors (CNIs) at baseline and on the final visit was 95% and 65%, respectively. The doses and mean levels of CNIs decreased between baseline and month 12 from 142.2 ± 51.6 to 98.0 ± 39.4 mg/d (P EVL was suspended in 44 patients (20%). Since the database was closed at the end of the study, no further follow-up data is available. Conversion to EVL in maintenance HT recipients allowed minimisation or suspension of the CNIs, with improved kidney function in the patients with nephrotoxicity, after 12 mo.

    The role of mTOR inhibitors, such as EVL, has not been established for pediatric liver transplant recipients up to now, although data from adult solid organ graft transplantation are very promising. Major complications following pediatric liver transplantation in the long-term course include chronic graft rejection and CNI-derived nephrotoxicity. The purpose of our study was to report first results using EVL as a rescue therapy in pediatric liver transplant recipients for the following indications: chronic graft dysfunction n=12, suspected CNI toxicity n=3, hepatoblastoma n=2, and recurrence of primary sclerosing cholangitis post-Ltx n=1. Four patients with chronic graft dysfunction developed completely normal liver function tests using EVL, six patients showed partial improvement, and two patients did not respond at all. One patient with CNI-induced nephropathy showed a slightly improved GFR. Both patients with hepatoblastoma did not develop any metastasis post-Ltx. First experience with EVL in pediatric liver transplant recipients shows promising results in patients with chronic graft failure when standard immunosuppression has failed. The future role of EVL in immunosuppressive protocols for children post-Ltx has to be proven by controlled clinical trials. © 2011 John Wiley & Sons A/S.

    Emerging adulthood (17-24 years) is a period of high risk for graft failure in kidney transplant. Whether a similar association exists in heart transplant recipients is unknown. We sought to estimate the relative hazards of graft failure at different current ages, compared with patients between 20 and 24 years old. We evaluated 11 473 patients recorded in the Scientific Registry of Transplant Recipients who received a first transplant at transplant and other potential confounders. Failure was defined as death following graft failure or retransplant; observation was censored at death with graft function. There were 2567 failures. Crude age-specific graft failure rates were highest in 21-24 year olds (4.2 per 100 person-years). Compared to individuals with the same time since transplant, 21-24 year olds had significantly higher failure rates than all other age periods except 17-20 years (HR 0.92 [95%CI 0.77, 1.09]) and 25-29 years (0.86 [0.73, 1.03]). Among young first heart transplant recipients, graft failure risks are highest in the period from 17 to 29 years of age. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    To determine the incidence, risk factors, and clinical outcomes associated with clinically significant medication errors or adverse drug events in kidney transplant recipients. Retrospective observational study. Transplant center at an academic medical center. A total of 476 adults who received kidney transplants between June 2006 and July 2009. Severe or significant medication errors and adverse drug events (medication-related problems [MRPs]) were identified by medical record review. Only patient-induced medication errors (e.g., took wrong dose or frequency of drug, took drug not prescribed) were captured. Clinical outcomes included patient and graft survival, infections (including cytomegalovirus), readmissions, and acute rejection episodes. Thirty-seven (8%) of the 476 patients developed a clinically significant MRP. Univariate and confirmatory multivariate analyses revealed that female sex, African-American race, pretransplantation diabetes mellitus, delayed graft function, and retransplant recipients were independent risk factors for developing an MRP. Patients with MRPs had significantly higher rates of acute rejection (11% vs 30%, p=0.004), cytomegalovirus infection (15% vs 30%, p=0.033), and 30-day readmissions (5% vs 16%, p=0.018). Graft survival was also significantly lower in patients who had MRPs (pmedication errors and associated adverse drug events were common in kidney transplant recipients. General and transplant-specific risk factors were associated with the development of these MRPs, and MRPs were associated with increased risk of rejection and graft loss. © 2012 Pharmacotherapy Publications, Inc.

    Although allogeneic hematopoietic cell transplantation (HCT) is an expensive treatment for hematological disorders, little is known about the financial consequences for the patients who undergo this procedure. We analyzed factors associated with its financial burden and its impact on health behaviors of allogeneic HCT recipients. A questionnaire was retrospectively mailed to 482 patients who underwent allogeneic HCT from January 2006 to June 2012 at the Mayo Clinic, to collect information regarding current financial concerns, household income, employment, insurance, out-of-pocket expenses, and health and functional status. A multivariable logistic regression analysis identified factors associated with financial burden and treatment nonadherence. Of the 268 respondents (56% response rate), 73% reported that their sickness had hurt them financially. All patients for whom the insurance information was available (missing, n = 13) were insured. Forty-seven percent of respondents experienced financial burden, such as household income decreased by >50%, selling/mortgaging home, or withdrawing money from retirement accounts. Three percent declared bankruptcy. Younger age and poor current mental and physical functioning increased the likelihood of financial burden. Thirty-five percent of patients reported deleterious health behaviors because of financial constraints. These patients were likely to be younger, have lower education, and with a longer time since HCT. Being employed decreased the likelihood of experiencing financial burden and treatment nonadherence due to concern about costs. A significant proportion of allogeneic HCT survivors experience financial hardship despite insurance coverage. Future research should investigate potential interventions to help at-risk patients and prevent adverse financial outcomes after this life-saving procedure.

    Respiratory muscles are known to be weakened and are a cause of reduced exercise capacity in both recipients and candidates of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Effects of inspiratory muscle training (IMT) in this patient population have not been comprehensively investigated so far. The current study was planned to investigate the effects of IMT during allo-HSCT on early transplantation-related outcomes. This is a prospective, randomized controlled, double-blinded study. Thirty-eight allo-HSCT recipients, 20 of whom were allocated to the treatment group (40 % of maximal inspiratory pressure (MIP)) and 18 to the control group (5 % of MIP), received IMT for 6 weeks. Pulmonary functions, dyspnea, respiratory (MIP, maximal expiratory pressure (MEP)) and peripheral muscle strength, maximal exercise capacity using modified incremental shuttle walking test (MISWT) and submaximal exercise capacity using 6-min walking test (6-MWT), fatigue, depression, and quality of life were evaluated before and after IMT. The distance covered during MISWT (61.94 m) and 6-MWT (29.30 m), respiratory muscle strength (MIP 34.99 cmH2O, MEP 12.69 cmH2O), depression (-0.95), and modified Borg dyspnea scores (-0.11) showed a significant improvement in the treatment group compared to controls (p ≤ 0.05). Inspiratory muscle training is a safe and effective intervention which improves respiratory muscle strength and exercise capacity and decreases depression and dyspnea in allo-HSCT recipients. These positive changes might be further enhanced by prolonging the duration of training or inclusion of more recipients with inspiratory muscle weakness. NCT02270346.

    Background There are limited published data on the characteristics of blood transfusion recipients in sub-Saharan Africa. This study describes the demographic characteristics of blood transfusion recipients and patterns of blood and blood component use in Zimbabwe. Materials and methods Data on the characteristics of the blood transfusion recipients (age, sex, blood group), blood components received (type, quantity), discharge diagnoses and outcomes following transfusion (discharge status, duration of stay in hospital), were retrospectively collected from four major hospitals for the period from January 1, 2012 to December 31, 2012. Diagnoses were grouped into broad categories according to the disease headings of the International Classification of Diseases (ICD-10). Surgical procedures were grouped into broad categories according to organ system using ICD-9. Results Most of the 1,793 transfusion recipients studied were female (63.2%) and in the reproductive age group, i.e. 15–49 years (65.3%). The median age of the recipients was 33 years (range, 0–93). The majority of these recipients (n=1,642; 91.6%) received a red blood cell transfusion. The majority of the patients were diagnosed with conditions related to pregnancy and childbirth (22.3%), and diseases of blood and blood-forming organs (17.7%). The median time spent in hospital was 8 days (range, 0–214) and in-hospital mortality was 15.4%. Discussion Our sample of blood transfusion recipients were fairly young and most of them received red blood cell transfusions. The majority of patients in the reproductive age group received blood transfusions for pregnancy and childbirth-related diagnoses. PMID:26192782

    Pulmonary infections are life-threatening complications in heart transplant recipients. Our aim was to evaluate long-term pulmonary infections and the effect of prophylactic antimicrobial strategies on time of occurrence of pulmonary infections in heart transplant recipients. Patients who underwent heart transplantation between 2003 and 2013 at Baskent University were reviewed. Demographic information and data about immunosuppression and infectious episodes were collected. In 82 heart transplant recipients (mean age, 33.85 y; 58 male and 24 female), 13 recipients (15.8%) developed pulmonary infections (mean age, 44.3 y; 9 male and 4 female). There were 12 patients who had dilated cardiomyopathy and 1 patient who had myocarditis before heart transplantation; 12 patients received immunosuppressive therapy in single or combination form. Pulmonary infections developed in the first month (1 patient), from first to third month (6 patients), from third to sixth month (1 patient), and > 6 months after transplantation (5 patients). Chest computed tomography showed consolidation (unilateral, 9 patients; bilateral, 4 patients). Multiple nodular consolidations were observed in 2 patients and a cavitary lesion was detected in 1 patient. Bronchoscopy was performed in 6 patients; 3 patients had Aspergillus fumigatus growth in bronchoalveolar lavage fluid, and 2 patients had Acinetobacter baumannii growth in sputum. Treatment was empiric antibiotics (6 patients), antifungal drugs (5 patients), and both antibiotics and antifungal drugs (2 patients); treatment period was 1-12 months in patients with invasive pulmonary aspergillosis. Pulmonary infections are the most common cause of mortality in heart transplant recipients. A. fumigatus is the most common opportunistic pathogen. Heart transplant recipients with fever and cough should be evaluated for pulmonary infections, and invasive pulmonary aspergillosis should be suspected if these symptoms occur within the first 3 months

    Kidney transplantation offers improved survival and quality of life to an increasing number of elderly patients with end-stage kidney disease. However, elderly kidney transplant recipients may face unique challenges due to a higher burden of comorbidity, greater cumulative risk of immunosuppression-related complications and increasing frailty. We aimed to describe the perspectives of elderly kidney transplant recipients. Electronic databases were searched to April 2015. Qualitative studies were eligible if they reported views from elderly kidney transplant recipients (≥60 years). Thematic synthesis was used to analyse the findings. Twenty-one studies involving >116 recipients were included. We identified seven themes. 'Regaining strength and vitality' meant valuing the physical and psychosocial improvements in daily functioning and life participation. 'Extending life' was the willingness to accept any organ, including extended criteria kidneys, to prolong survival. 'Debt of gratitude' entailed conscious appreciation toward their donor while knowing they were unable to repay their sacrifice. 'Moral responsibility to maintain health' motivated adherence to medication and lifestyle recommendations out of an ethical duty to protect their gift for graft survival. 'Unabating and worsening forgetfulness' hindered self-management. 'Disillusionment with side effects and complications' reflected disappointment and exasperation with the unintended consequences of medications. 'Finality of treatment option' was an acute awareness that the current transplant may be their last. Kidney transplantation was perceived to slow and even reverse the experience of aging among elderly recipients, especially compared with dialysis. However, some were frustrated over persistent limitations after transplant, struggled with the burden of medication side effects and worried about a possible return to dialysis if the transplant failed.

    Mouse spleen cells were separated into adherent (Ad) and nonadherent (Nad) populations by incubation in plastic petri dishes. Adherent, Nad and unfractionated cell preparations (UCP) were transferred into syngeneic recipient mice that had been either irradiated or cyclophosphamide (CY) treated and the adoptive humoral Ab responses were studied by assessment of hemolytic Ab-forming cells (PFC) or humoral serum Ab production. Adherent cells failed to produce PFC in irradiated recipients, but functioned vigorously in CY-treated recipients. Nonadherent cells generated PFC in either type of host, as did UCP. Studies of comparative responses in CY-treated recipients revealed that: (a) Ad-cells generated 2 / 3 the number of PFC given by equivalent numbers of transferred Nad cells and UCP; (b) per equivalent numbers of transferred cells the Ad fraction generated 5 times more and 16 times more Ab than did the Nad cells and UCP, respectively. Spleen cells taken from mice 6 hr after CY treatment failed to respond to the mitogens phytohemagglutinin and bacterial lipopolysaccharide, showing that all cells were temporarily incapable of proliferation. Transfer of spleen cells from donor mice 16 hr after CY treatment, into thymectomized, irradiated, bone marrow-reconstituted recipients revealed substantial T-helper cell activity. We conclude that: (a) Ad preparations lacked T cells that were supplied by CY-treated recipients although T cell proliferation was temporarily inhibited in the latter; (b) B cells present in the Ad fraction were removed from some type of inhibitor of Ab synthesis and/or secretion, the production of which may be associated with T cells present in Nad preparations and UCP; (c) T-helper cells were only transiently affected by CY

    Relatively smaller kidney donor to recipient size is proposed to result in higher graft loss due to nephron underdosing and hyperfiltration injury, but the potentially additive effect of sex and weight mismatch has not been explored in detail. The purpose of this study was to determine if concurrent donor and recipient absolute weight and sex mismatch was associated with graft loss in a cohort of deceased donor kidney transplant recipients. The association of kidney donor and recipient absolute weight and sex difference with death-censored graft loss was explored using a cohort of United States deceased donor recipients between 2000 and 2014 through the Scientific Registry of Transplants Recipients. Donor-recipient sex pairings (male donor-male recipient; female donor-female recipient; male donor-female recipient; female donor-male recipient) were further stratified by donor and recipient absolute weight difference (>30 or 10-30 kg [donorrecipient] or mismatch (30 kg larger than donor (hazard ratio, 1.50; 95% confidence interval, 1.32 to 1.70; hazard ratio, 1.35; 95% confidence interval, 1.25 to 1.45, respectively). A concurrent mismatch in donor-recipient weight (donor<recipient) and donor-recipient sex is associated with a higher risk of death-censored graft loss in kidney transplantation.

    Over the last decade, liver transplantation of sicker, older non-hepatitis C cirrhotics with multiple co-morbidities has increased in the United States. We sought to identify an easily applicable set of recipient factors among HCV negative adult transplant recipients associated with significant morbidity and mortality within five years after liver transplantation. We collected national (n = 31,829, 2002-2015) and center-specific data. Coefficients of relevant recipient factors were converted to weighted points and scaled from 0-5. Recipient factors associated with graft failure included: ventilator support (five patients; hazard ratio [HR] 1.59; 95% CI 1.48-1.72); recipient age >60 years (three patients; HR 1.29; 95% CI 1.23-1.36); hemodialysis (three patients; HR 1.26; 95% CI 1.16-1.37); diabetes (two patients; HR 1.20; 95% CI 1.14-1.27); or serum creatinine ≥1.5 mg/dl without hemodialysis (two patients; HR 1.15; 95% CI 1.09-1.22). Graft survival within five years based on points (any combination) was 77.2% (0-4), 69.1% (5-8) and 57.9% (>8). In recipients with >8 points, graft survival was 42% (model for end-stage liver disease [MELD] score recipients receiving grafts from donors with a donor risk index >1.7. In center-specific data within the first year, subjects with ≥5 points (vs. 0-4) had longer hospitalization (11 vs. 8 days, p need to be reassessed. The proposed clinical tool may be helpful for center-specific assessment of risk of graft failure in non-HCV patients and for discussion regarding relevant morbidity in selected subsets. Over the last decade, liver transplantation of sicker, older patient with multiple co-morbidities has increased. In this study, we show that a set of recipient factors (recipient age >60 years, ventilator status, diabetes, hemodialysis and creatinine >1.5 mg/dl) can help identify patients that may not do well after transplant.

    Learning electrically stimulated speech patterns can be a new and difficult experience for cochlear implant (CI) recipients. Recent studies have shown that most implant recipients at least partially adapt to these new patterns via passive, daily-listening experiences. Gradually introducing a speech processor parameter (eg, the degree of spectral mismatch) may provide for more complete and less stressful adaptation. Although the implant device restores hearing sensation and the continued use of the implant provides some degree of adaptation, active auditory rehabilitation may be necessary to maximize the benefit of implantation for CI recipients. Currently, there are scant resources for auditory rehabilitation for adult, postlingually deafened CI recipients. We recently developed a computer-assisted speech-training program to provide the means to conduct auditory rehabilitation at home. The training software targets important acoustic contrasts among speech stimuli, provides auditory and visual feedback, and incorporates progressive training techniques, thereby maintaining recipients’ interest during the auditory training exercises. Our recent studies demonstrate the effectiveness of targeted auditory training in improving CI recipients’ speech and music perception. Provided with an inexpensive and effective auditory training program, CI recipients may find the motivation and momentum to get the most from the implant device. PMID:17709574

    Extra-pulmonary tuberculosis (TB) is more common in renal allograft recipients and may present with dissemination or an atypical features. We report a renal allograft recipient with intestinal TB presenting 3 years after transplantation with persistent fever, weight loss, diarrhea, abdominal pain and mass in the abdomen with intestinal obstruction. He was diagnosed to be having an ileocolic intussusception which on resection showed a granulomatous inflammation with presence of acid-fast bacilli (AFB) typical of Mycobacterium tuberculosis. In addition, AFB was detected in the tracheal aspirate, indicating dissemination. He received anti-TB therapy (ATT) from the fourth postoperative day. However, he developed a probable immune reconstitution inflammatory syndrome (IRIS) with multiorgan failure and died on 11(th) postoperative day. This is the first report of intestinal TB presenting as intussusception in a renal allograft recipient. The development of IRIS after starting ATT is rare in renal allograft recipients. This report highlights the need for a high index of suspicion for diagnosing TB early among renal transplant recipients and the therapeutic dilemma with overwhelming infection and development of IRIS upon reduction of immunosuppression and starting ATT.

    Annual influenza vaccination is recommended in solid organ transplant (SOT) recipients. However, concerns have been raised about the impact of vaccination on antigraft alloimmunity. We evaluated the humoral alloimmune responses to influenza vaccination in a cohort of SOT recipients between October 2008 and December 2011. Anti-HLA antibodies were measured before and 4-8 weeks after influenza vaccination using a solid-phase assay. Overall, 169 SOT recipients were included (kidney = 136, lung = 26, liver = 3, and combined = 4). Five (2.9%) of 169 patients developed de novo anti-HLA antibodies after vaccination, including one patient who developed donor-specific antibodies (DSA) 8 months after vaccination. In patients with pre-existing anti-HLA antibodies, median MFI was not significantly different before and after vaccination (P = 0.73 for class I and P = 0.20 for class II anti-HLA antibodies) and no development of de novo DSA was observed. Five episodes of rejection (2.9%) were observed within 12 months after vaccination, and only one patient had de novo anti-HLA antibodies. The incidence of development of anti-HLA antibodies after influenza vaccination in our cohort of SOT recipients was very low. Our findings indicate that influenza vaccination is safe and does not trigger humoral alloimmune responses in SOT recipients. © 2014 Steunstichting ESOT.

    Invasive fungal infections are a major complication and an important cause of morbidity and mortality among solid organ transplant recipients. Their diagnosis is difficult and their prognosis is often pejorative. The aim of this study was to report the cases of invasive fungal infections in renal transplant recipients in Habib Bourguiba Sfax university hospital and to identify the main fungal agents. It is a retrospective study of invasive fungal infections in renal transplant recipient reported in our hospital from January 1995 to February 2013. Invasive fungal infections were diagnosed in 11 cases (3.4%) among 321 renal transplant recipients. These infections included four cases of pneumocystosis, two cases of candidiasis, two cases of aspergillosis, two cases of cryptococcosis and one case of mucormycosis. There were six men and five women. The mean age was 37 years. The infection was late in 63% of cases (>3 months after transplantation). The prolonged corticosteroid and immunosuppressive therapy were the main risk factors (100%) followed by renal failure (45%), graft rejection (45%), broad spectrum antibiotics (45%), CMV infection (36%), neutropenia (36%) and dialysis (18%). The evolution under treatment was favourable only in two cases (18%). Invasive fungal infections are not common among kidney transplant recipients. However, they remain an important cause of morbidity and mortality in this group of patients. Prevention, early diagnosis and appropriate management are necessary to improve prognosis and reduce mortality rate. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Acute cellular rejection (ACR), a reversible process, can affect the graft survival. To evaluate the relation between ACR and clinical factors in recipients of allograft liver transplantation. 47 recipients of liver were consecutively enrolled in a retrospective study. Their information were retrieved from their medical records and analyzed. Of the 47 recipients, 38 (81%) experienced acute rejection during 24 months of the transplantation. None of the studied factors for occurring transplant rejection, i.e ., blood groups, sex, age, familial history of disease, receiving drugs and blood products, type of donor, Child score, and Child class, was not found to be significant. During a limited follow-up period, we did not find any association between ACR and suspected risk factors.

    Welfare recipients are continuously subjected to media debates and governmental campaigns drawing on images and symbols encouraging improved work ethic and individual responsibility. Only few studies, however, have analysed how welfare recipients as ‘othered’ citizens react to these often...... stereotypical symbols and images targeting them. In this study we have investigated how welfare recipients in Norway and Denmark, and caseworkers in Denmark, understand and account for images which, through the use of stereotypes, directly or indirectly may question welfare recipients’ work ethic...... and deservedness. Analysing photo-elicitation interview data, we have uncovered a variety of reactions characterized by ‘problematization’. The interviewees problematize the image and depicted stereotypes, which they link both with motif and symbols and with surrounding public debates on the work ethic...

    Cryptococcal meningitis is a relatively common invasive fungal infection in immunocompromised patients, especially in solid organ transplant recipients. Clinical presentation typically includes fever, headache, photophobia, neck stiffness, and/or altered mental status. Unusual presentations may delay diagnosis. Therapy is challenging in renal transplant patients because of the nephrotoxicity associated with amphotericin B, the recommended treatment. We present a case of cryptococcal meningitis in a renal transplant recipient presenting as acute sinusitis with successful treatment using fluconazole as primary therapy. © 2013 John Wiley & Sons A/S.

    2015-01-01

    Full Text Available Current immunosuppression improved long-term outcome of transplant patients, but it also increased the incidence of de novo malignancy. Organ transplant recipients have a threeto four-fold increased risk of developing carcinoma in comparison with the general population. Common malignancies encountered after transplantation include cancer of the skin, lips, post-transplant lymphoproliferative disease, ano-genital carcinoma and Kaposi sarcoma. Squamous cell carcinoma of the tongue is very rare. We report here a case of squamous cell carcinoma of the tongue in an adult male patient who developed it 11 years post-transplant. He underwent right hemiglossectomy and his graft function remained stable.

    Secondary hyperparathyroidism is highly prevalent in kidney transplant recipients, and commonly results in hypercalcaemia; an association to osteopenia and bone fractures has also been observed. Paricalcitol has proved effective to control secondary hyperparathyroidism in chronic kidney disease in both dialysed and non-dialysed patients, with a low hypercalcaemia incidence. Currently available experience on paricalcitol use in kidney transplant recipients is scarce. Our main aim was to show the effect of paricalcitol on mineral bone metabolism in kidney transplant recipients with secondary hyperparathyroidism. A retrospective multicentre study in kidney transplant recipients aged>18 years with a 12-month or longer post-transplantation course, stable renal function, having received paricalcitol for more than 12 months, with available clinical follow-up for a 24-month period. A total of 69 patients with a 120 ± 92-month post-transplantation course were included. Baseline creatinine was 2.2 ± 0.9 mg/dl y GFR-MDRD was 36 ± 20 ml/min/1.73 m(2). Paricalcitol doses were gradually increased during the study: baseline 3.8 ± 1.9 μg/week, 12 months 5.2 ± 2.4 μg/week; 24 months 6.0 ± 2.9 μg/week (P10mg/dl showed gradually decreasing levels. Fifteen (21.7%) patients had received prior calcitriol therapy. When shifted to paricalcitol, such patients required paricalcitol doses significantly larger than those not having received calcitriol. Paricalcitol was used concomitantly to cinacalcet in 11 patients with significant PTH reductions being achieved; clinical course was similar to other patients and paricalcitol doses were also similar. Paricalcitol is an effective therapy for secondary hyperparathyroidism in kidney transplant recipients. Overall, no significant changes were observed in calcium and phosphorus levels or urinary excretion. Patients having previously received calcitriol required higher paricalcitol doses. When used in patients receiving cinacalcet

    Early detection of subclinical lung function decline may help identify allogeneic hematopoietic cell transplant (HCT) recipients who are at increased risk for late noninfectious pulmonary complications, including bronchiolitis obliterans syndrome. We evaluated the use of handheld spirometry in this population. Allogeneic HCT recipients enrolled in a single-center observational trial performed weekly spirometry with a handheld spirometer for 1 year after transplantation. Participants performed pulmonary function tests in an outpatient laboratory setting at 3 time points: before transplantation, at day 80 after transplantation, and at 1 year after transplantation. Correlation between the 2 methods was assessed by Pearson and Spearman correlations; agreement was assessed using Bland-Altman plots. A total of 437 subjects had evaluable pulmonary function tests. Correlation for forced expiratory volume in 1 second (FEV1) was r = .954 (P spirometry correlated well with laboratory spirometry after allogeneic HCT and may be useful for self-monitoring of patients for early identification of airflow obstruction.

    Both donor and recipient race impact outcomes after liver transplantation (LT), especially for hepatitis C virus (HCV). The interaction and simultaneous impact of both on patient survival is not clearly defined. The purpose of this study was to examine the impact of donor and recipient race on recipient and graft survival after HCV-related LT using the United Network for Organ Sharing database. A total of 16,053 recipients (75.5% white, 9.3% black, and 15.2% Hispanic) who underwent primary LT for HCV between 1998 and 2008 were included. Cox regression models were used to assess the association between recipient/donor race and patient survival. A significant interaction between donor and recipient race was noted (P=0.01). Black recipients with white donors had a higher risk of patient mortality (adjusted hazard ratio, 1.66; 95% confidence interval, 1.47-1.87) compared with that of white recipients with white donors. In contrast, the pairing of Hispanic recipients with black donors was associated with a lower risk of recipient mortality compared with that of white recipients with white donors (adjusted hazard ratio, 0.64; 95% confidence interval, 0.46-0.87). Similar results were noted for graft failure. In conclusion, the impact of donor and recipient race on patient survival varies substantially by the matching of recipient/donor race.

    Embryo donation, as one of the novel assisted reproductive technologies (ART), has remained a controversial issue. This is due to this methods' need for individuals from outside the family circle. Their presence can cause many ethical issues and complicate the designing and planning of the embryo donation process. The present study was conducted with the aim to assess the ethical challenges of embryo donation from the view point of embryo donors and recipients. This descriptive, cross-sectional study was conducted on 192 couples (96 embryo donators and 96 embryo recipients) referring to Isfahan Fertility and Infertility Center and Royan Institute, Iran. The subjects were selected through convenience sampling. The data collection tool was the researcher-made Ethical Challenges Questionnaire. Data were analyzed in SPSS software. Embryo donors and recipients expresses the most important ethical challenges of embryo donation in the principle of justice (70.20%) and respect for autonomy (42.57%), respectively. The four ethical principles are important in the view of embryo donors and recipients; however, they highlighted the importance of the principle of respect for autonomy considering the existing barriers in the services of infertility centers. Legislators and relevant authorities must take measures toward the development of guidelines for this treatment method in the framework of ethics principles and incorporate all four principles independently.

    Full Text Available Background & objectives: Diarrhoea is the main clinical manifestation caused by intestinal parasitic infections in patients, with special reference to transplant recipients who require careful consideration to reduce morbidity and mortality. Further, molecular characterization of some important parasites is necessary to delineate the different modes of transmission to consider appropriate management strategies. We undertook this study to investigate the intestinal parasitic infections in transplant recipients with or without diarrhoea, and the genotypes of the isolated parasites were also determined. Methods: Stool samples from 38 transplant recipients comprising 29 post-renal, two liver and seven bone marrow transplant (BMT recipients presenting with diarrhoea and 50 transplant recipients (42 post-renal transplant, eight BMT without diarrhoea were examined for the presence of intestinal parasites by light microscopy using wet mount, modified Ziehl-Neelsen staining for intestinal coccidia and modified trichrome staining for microsporidia. Genotypes of Cryptosporidium species were determined by multilocus genotyping using small subunit ribosomal (SSUrRNA, Cryptosporidium oocyst wall protein (COWP and dihydrofolate reductase (DHFR as the target genes. Assemblage study for Giardia lamblia was performed using triose phosphate isomerase (TPI as the target gene. Samples were also screened for bacterial, fungal and viral pathogens.

    Solid-organ transplant recipients present a high rate of non-adherence to drug treatment. Few interventional studies have included approaches aimed at increasing adherence. The objective of this study was to evaluate the impact of an educational and behavioral strategy on treatment adherence of kidney transplant recipients. In a randomized prospective study, incident renal transplant patients (n = 111) were divided into two groups: control group (received usual transplant patient education) and treatment group (usual transplant patient education plus ten additional weekly 30-min education/counseling sessions about immunosuppressive drugs and behavioral changes). Treatment adherence was assessed using ITAS adherence questionnaire after 3 months. Renal function at 3, 6, and 12 months, and the incidence of transplant rejection were evaluated. The non-adherence rates were 46.4 and 14.5 % in the control and treatment groups (p = 0.001), respectively. The relative risk for non-adherence was 2.59 times (CI 1.38-4.88) higher in the control group. Multivariate analysis demonstrated a 5.84 times (CI 1.8-18.8, p = 0.003) higher risk of non-adherence in the control group. There were no differences in renal function and rejection rates between groups. A behavioral and educational strategy addressing the patient's perceptions and knowledge about the anti-rejection drugs significantly improved the short-term adherence to immunosuppressive therapy.

    Kidney transplant outcomes are influenced by donor characteristics, including age and gender. Additional donor factors, both genetic and environmental, also influence graft outcome. We aim to assess the strength of donor factors in determining kidney transplant outcomes by comparing paired kidneys from a single donor transplanted into different recipients. We conducted a retrospective cohort study of outcomes of pairs of deceased donor kidneys transplanted in our centre between 1992 and 2008. We examined the relationship within pairs for eGFR at 1 year and at 5 years post-transplant using Spearman\\'s Correlation and the concordance of pairs of transplant kidneys with respect to the occurrence of acute rejection and delayed graft function (DGF). A total of 652 recipient pairs were analysed. Spearman\\'s correlation for eGFR was 0.36 at 1 year and 0.36 at 5 years post-transplant. The incidence of DGF was 11%. The odds ratio of DGF occurring if the contralateral kidney had DGF was 5.99 (95% CI, 3.19-11.25). There is a significant degree of relationship within pairs of kidneys transplanted from the same donor for serum creatinine at 1 year and 5 years post-transplant and also for the occurrence of delayed graft function.

    Conclusion: Depression is common among RT recipients in China. Employment status, economic burden, inhabitation area, and social support are the main factors affecting depression among RT recipients. Follow-up clinics should prescribe the evaluation of depression as a routine examination for RT patients. Moreover, depressed recipients must be provided with individualized care by collecting information on the depressive symptoms, employment status, economic burden, inhabitation area, and perceived social support of recipients.

    Blood transfusion is one of the most common medical procedures during hospitalization in the United States. To understand the benefits of transfusion while mitigating potential risks, a multicenter database containing detailed information on transfusion incidence and recipient outcomes would facilitate research. The Recipient Epidemiology and Donor Evaluation Study-III (REDS-III) program has developed a comprehensive transfusion recipient database utilizing data from hospital electronic health records at 12 participating hospitals in four geographic regions. Inpatient and outpatient data on transfusion recipients from January 1, 2013 to December 31, 2014 included patient age, sex, ethnicity, primary diagnosis, type of blood product provided, issue location, pretransfusion and post-transfusion hemoglobin (Hgb), and hospital outcomes. Transfusion incidence per encounter was calculated by blood product and various patient characteristics. During the 2-year study period, 80,362 (12.5%) inpatient encounters involved transfusion. Among inpatients, the most commonly transfused blood products were red blood cells (RBCs; 10.9% of encounters), followed by platelets (3.2%) and plasma (2.9%). Among patients who received transfusions, the median number of RBC units was one, the pretransfusion Hgb level was 7.6 g/dL, and the Hgb increment per unit was 1.4 g/dL. Encounter mortality increased with patient age, the number of units transfused, and the use of platelet or plasma products. The most commonly reported transfusion reaction was febrile nonhemolytic. The database contains comprehensive data regarding transfusion use and patient outcomes. The current report describes an evaluation of the first 2 years of a planned, 4-year, linked blood donor-component-recipient database, which represents a critical new resource for transfusion medicine researchers. © 2017 AABB.

    Prior research on donor monoclonal gammopathy of undetermined significance (MGUS) has been inadequate regarding the risk for lymphoproliferative disease in solid organ transplantation recipients. Seven organ recipients from two different donors developed lymphoproliferative disease. The origin of the malignancy was determined by use of microsatellite analysis, and the plasma of the two donors was analyzed with the use of electrophoresis. The clinical courses of the seven recipients were followed for 36-60 months. One donor transmitted lymphoplasmacytic lymphoma to two kidney recipients and MGUS to a liver recipient, all IgMκ. A second donor caused IgGλ myeloma in two kidney and one liver recipient, and IgGλ gammopathy in a heart recipient. Transplant nephrectomy was performed in three kidney recipients and remission was achieved. The fourth kidney recipient has kept the graft and the disease has progressed. The liver recipient died from myeloma. There were no clinical signs of lymphoproliferative disease in the donors, but retrospective serum analyses showed M-components, IgMκ (37 g/L) and IgGλ (8 g/L). Donors with MGUS may cause donor-transmitted malignancies via passenger lymphocytes/plasma cells in solid organ recipients. The results call for a large register study of the incidence of donor MGUS and lymphoproliferative disease in their recipients. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    One of the most common malignancies in kidney transplant recipients is Kaposi sarcoma. The incidence of Kaposi sarcoma, which develops after renal transplantation, is 400-500 times higher than that in the general population. The aims of this study were to review the experience with Kaposi sarcoma in the highest-volume transplantation Unit in Greece and to analyze clinical characteristics and response to treatment, with respect to both the patients' survival and the renal graft function. The records of 2008 renal graft recipients between March 1983 and December 2012 were retrospectively reviewed. Kaposi sarcoma was diagnosed based on clinical, laboratory, radiological, endoscopic, and histopathologic examinations. The disease was staged according to the classification of Al-Khader et al. The prevalence of Kaposi sarcoma was 1.2% in our renal transplant population. Of these, 1006 recipients underwent living-donor renal transplantation, whereas 1002 received their graft from deceased donors. Post-transplantation malignancy developed in 153 patients, among which, Kaposi sarcoma has been found in 24 cases. Of the 24 cases of Kaposi sarcoma, lesions were mainly cutaneous in 14 cases, visceral and cutaneous in 8, and concomitant visceral and lymph node involvement was observed in 2 patients. With regard to the final outcome, 20 patients (83.3%) showed remission of the disease, whereas 4 patients with visceral involvement (16.6%) did not respond to chemotherapy and discontinuation of immunosuppression and died. Moreover, 8 deaths occurred due to apparently unrelated causes. Kaposi sarcoma is an important part (15.7%) of all post-transplantation neoplasias in our series. Furthermore, our findings confirmed the previously described close association between human herpesvirus-8 and post-transplantation Kaposi sarcoma. Reduction of immunosuppression or discontinuation of calcineurin inhibitors results in remission of the disease in most of the cases. Prognosis in patients with

    Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. Ureteric stents have been successfully used to treat such complications and a number of centers have adopted a policy of universal prophylactic stenting, at the time of graft implantation, to reduce the incidence of urine leaks and ureteric stenosis. In conjunction with the Cochrane Renal Group we searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, reference lists of articles, books and abstracts and contacted companies, authors and experts to identify randomized controlled trials examining the use of stents in renal transplantation. The primary outcome was the incidence of MUCs and data on this statistic was pooled and analyzed using a random effects model. Seven randomized controlled trials (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (relative risk [RR] 0.24; 95% CI: 0.07 - 0.77; P=0.02; number needed to treat = 13) by prophylactic ureteric stenting. Urinary tract infections were more common in stented patients (RR 1.49), unless the patients were prescribed 480 mg cotrimoxazole once daily. With this antibiotic regime the incidence of infection was equivalent between the two groups (RR 0.97). Stents appeared generally well tolerated, although trials using longer stents (> or = 20 cm) for longer periods of time (>6 weeks) reported more problems with encrustation and migration. Universal prophylactic stenting reduces the incidence of MUCs and should be recommended on the basis of currently available randomized controlled trials.

    To assess the hearing preservation outcomes in a large group of adult cochlear implant recipients implanted with a thin straight electrode array using atraumatic surgical techniques. Factors affecting hearing preservation will be investigated. Prospective cohort study undertaken at the Royal Victorian Eye and Ear Hospital in Melbourne, Australia from December 2010 to May 2015. Tertiary academic hospital. One hundred thirty-nine adults undergoing cochlear implantation (CI). Primary outcome measure of interest was pre and postoperative pure-tone audiometry. Median low-frequency hearing change for the whole group of 139 recipients was -22.5 dB at the 3 months postop point. Eighty-six participants had functional preoperative low-frequency hearing (≤70 dB average at 250 and 500 Hz). Of these, 90.7% retained measureable hearing at 3 months postimplant. 39.5% of this original 86 participants retained functional hearing at 3 months postimplant. At 12 months postimplant, those who retained functional hearing at 3 months had no significant change in hearing. The group who lost functional hearing continued to have a significant deterioration in low-frequency hearing. Degree of hearing loss preimplant was identified as a predictor for the preservation of hearing postoperatively. Preservation of hearing is possible following atraumatic cochlear implant surgery with a thin straight electrode array. The amount of hearing preserved seems to be variable, and factors related to this variability are not yet known. The results of the present study suggest preoperative low-frequency hearing at or better than 45 dB may be related to preservation of functional hearing.

    Liver transplantation (LT) is the gold standard treatment for end-stage liver disease. Whatever the primary indication of LT, substance abuse after surgery may decrease survival rates and quality of life. Prevalence of severe alcohol relapse is between 11 and 26%, and reduces life expectancy regardless of the primary indication of LT. Many patients on waiting lists for LT are smokers and this is a major risk factor for both malignant tumors and cardiovascular events post-surgery. The aim of this review is to describe psychoactive substance consumption after LT, and to assess the impact on liver transplant recipients. This review describes data about alcohol and illicit drug use by transplant recipients and suggests guidelines for behavior management after surgery. The presence of an addiction specialist in a LT team seems to be very important.

    Since the initial successful kidney transplantations in humans, the field of renal transplantation has made significant progress. Patient survival and graft survival have improved tremendously. Our armamentarium of immunosuppressive drugs and antimicrobial agents has expanded, as our understanding of their effects and proper utilization. Enhanced surgical techniques also improved the overall survival of kidney recipients. However, infectious complications remain a major cause of morbidity and mortality in this patient population. In this article, we provide an overview of infections in kidney transplant recipients, a detailed illustration of specific infectious agents with a focus on cytomegalovirus, and finally we lay some general principles for limiting the burden of infectious complications in kidney transplants through proper infection control measures.

    Full Text Available Allograft rejection remains a major barrier to successful organ transplan-tation. Cellular and humoral immune responses play a critical role in mediating graft rejection. During the last few years, monoclonal antibodies have been used as a new specific therapeutic approach in the prevention of allograft rejection. Recently, the technology of flow cytometry has become a useful tool for monitoring immunological responses in transplant recipients. The application of this valuable tool in clinical transplantation at the present time is aimed at, i determining the extent of immuno-suppressive therapy through T-cell receptor analysis of cellular components, ii monitoring levels of alloreactive antibodies to identify high-risk recipients (sensitized patients in the pre-operative period and iii to predict rejection by monitoring their development post-operatively. In future, further development of this technology may demonstrate greater benefit to the field of organ transplantation.

  17. Alcohol and substance abuse in solid-organ transplant recipients.

    This review focuses on alcohol and substance abuse in the context of solid-organ transplantation. Alcohol and substance abuse are common and may lead to a need for solid-organ transplantation and may also contribute to significant physical and psychologic problems that impact upon the recipient. Damaging levels of alcohol intake can occur in the absence of dependence. Alcohol or substance abuse after transplantation is associated with poor medication compliance and this may increase risk of graft loss. Intravenous drug use is associated with increased risk of infections (especially secondary to opportunistic organisms-bacterial, viral, protozoal, and others-and such infections may be more severe in the immunosuppressed), but there is only anecdotal evidence that such behavior has a worse outcome in transplant recipients. Whereas previous alcohol excess and drug use in kidney recipients are both associated with a small but statistically significantly increased risk of adverse outcomes (hazard ratio, 1.16-1.56), alcohol use within recommended guidelines after transplantation appears safe and possibly beneficial. Robust data are lacking for other organs, but those available suggest that heart transplantation is safe in individuals with a history of alcohol or substance abuse. Health specialists in drug or alcohol addiction should carefully screen all potential transplant candidates for these conditions, and where there is evidence of dependency or abuse, effective psychologic and physical treatment should be offered. Studies have shown that interventions such as psychologic intervention have improved alcohol behavior in the context of liver transplantation. Although there are no comparable studies with other solid-organ recipients, it is reasonable to expect transferable outcomes.

    Applying Rusbult's investment model of dyadic relationships, we examined the effect of caregiver–care recipient relationship closeness (RC) on cognitive and functional decline in Alzheimer's disease. After diagnosis, 167 participants completed up to six visits, observed over an average of 20 months. Participants were 64% women, had a mean age of 86 years, and mean dementia duration of 4 years. Caregiver-rated closeness was measured using a six-item scale. In mixed models adjusted for dementia severity, dyads with higher levels of closeness (p caregivers (p = .01) had slower cognitive decline. Effect of higher RC on functional decline was greater with spouse caregivers (p = .007). These findings of attenuated Alzheimer's dementia (AD) decline with closer relationships, particularly with spouse caregivers, are consistent with investment theory. Future interventions designed to enhance the caregiving dyadic relationship may help slow decline in AD. PMID:19564210

    Cytomegalovirus (CMV) infection remains a major cause of morbidity, graft failure, and death in kidney transplant recipients. We describe a case of a 53-year-old CMV-seronegative man who underwent renal transplant from a CMV-positive donor and who developed ganciclovir- (GCV-) resistant CMV infection. Foscarnet was started while immunosuppressive therapy was modified with the introduction of everolimus minimizing tacrolimus dosage. Only two weeks after the start of this treatment regimen was the patient's viral load negative. At two-year follow-up the patient has no clinical or laboratory signs of CMV infection and a good and stable renal function or graft survival. In our case, administration of an mTOR inhibitor combined with foscarnet led to rapid and persistent viral clearance without compromising short- and medium-term graft function. This combination therapy supports the need for the kidney transplant community to individualize a target therapy for each type of GCV-resistant CMV infection.

    Full Text Available Acute renal failure can be caused by calcineurin inhibitors (CNIs, due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration. In conclusion, a hypercaloric diet in children with potentially impaired renal function due to therapy with CNIs requires precise calculation of the potential renal solute load and the associated fluid requirements.

    Sirolimus is an immunosuppressive drug that has been used during the past few years. Sirolimus is indicated in rescue therapies and to reduce the secondary toxic effects of calcineurin inhibitors. This drug has been associated with infrequent but severe pulmonary toxicity. Cases of interstitial pneumonitis, bronchiolitis obliterans with organizing pneumonia, and alveolar proteinosis have been described. We describe a case of pulmonary toxicity associated with the use of sirolimus in a 59-yr-old liver transplant recipient. We also review all reported cases of sirolimus-associated lung toxicity among liver transplantation recipients, with the intention of understanding the risk factors, the clinical picture and the outcomes of this complication. Five cases have been reported since January 2000, including the present case. Clinical presentation is similar, with fever, dyspnoea, fatigue, cough, and hemoptysis. Discontinuation of the drug led to resolution of clinical and radiographic findings. Sirolimus-induced pulmonary toxicity is a serious condition and should be considered in the differential diagnosis of liver recipients presenting with respiratory findings. Discontinuation of the drug is associated with resolution of the pulmonary compromise

In this cross sectional descriptive study we evaluated the socio-economic status of 100 KT recipients in Shiraz organ transplantation center. In a cross-sectional design, we randomly selected and interviewed 100 RT recipients (50 males and 50 females. Data regarding age, gender, martial status, occupation, level of education, number of children, type of insurance, monthly household income, place of residence, ownership of a personal transportation device, duration and frequency of pre-transplant dialysis, family history of CRF (Chronic renal failure, and etiology of renal disease were obtained. There were 50 (50% patients aged between 16 and 35 years, 55 had a family history of CRF, 60 had been on dialysis for more than a year, 61 were married, 47 did not have any children, 41 had more than 3 children, and 65 were unemployed due to physical and emotional impairment as a result of their disease. The majority (73% did not have a high school diploma, 15% were illiterate, 85% were below the poverty line, 52% were from rural areas, and 98% were covered by insurance. We conclude that patients with CKD in our study had acquired this condition possibly due to negligence and lack of basic health care in the lower socioeconomic class. In addition, KT is an available therapeutic modality to lower socio-economic level in Iran.

    The 2006 welfare reform legislation (Deficit Reduction Act of 2005) imposed more stringent work requirements and defined the amount of time cash assistance recipients are allowed to be exempted from the work requirement because of substance use treatment. As there is little empirical literature on the employability of substance users, it is difficult to know whether it is realistic to expect individuals with substance use disorders to meet the increased work requirement. Based on a comprehensive evaluation of nearly 9,000 substance-misusing welfare recipients from 2001 to 2007, University Behavioral Associates (UBA) Comprehensive Services Model program in Bronx, New York, found that 60% of recipients were not exempted from the work requirement owing to substance misuse at the outset, and an additional 24% were found nonexempt after 3 months of intensive outpatient treatment coupled with case management, resulting in a total of 84% of the UBA clients not being exempted from the work requirement because of substance misuse by Day 90. UBA also found that 25% of substance-misusing clients were able to obtain employment, and most successfully retained those jobs over the course of 6 months. These findings are discussed in relation to the new law's work requirements and the issue of the employability of substance misusers. Finally, the value of case management in serving this hard-to-engage population is discussed.

    Sirolimus has anti-carcinogenic properties and can be included in maintenance immunosuppressive therapy following kidney transplantation. We investigated sirolimus effects on cancer incidence among kidney recipients. The US transplant registry was linked with 15 population-based cancer registries and national pharmacy claims. Recipients contributed sirolimus-exposed time when sirolimus claims were filled, and unexposed time when other immunosuppressant claims were filled without sirolimus. Cox regression was used to estimate associations with overall and specific cancer incidence, excluding nonmelanoma skin cancers (not captured in cancer registries). We included 32,604 kidney transplants (5687 sirolimus-exposed). Overall, cancer incidence was suggestively lower during sirolimus use (hazard ratio [HR] = 0.88, 95% confidence interval [CI] = 0.70-1.11). Prostate cancer incidence was higher during sirolimus use (HR = 1.86, 95% CI = 1.15-3.02). Incidence of other cancers was similar or lower with sirolimus use, with a 26% decrease overall (HR = 0.74, 95% CI = 0.57-0.96, excluding prostate cancer). Results were similar after adjustment for demographic and clinical characteristics. This modest association does not provide strong evidence that sirolimus prevents posttransplant cancer, but it may be advantageous among kidney recipients with high cancer risk. Increased prostate cancer diagnoses may result from sirolimus effects on screen detection. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Malignancy following renal transplantation remains inconsistent with the reported safety of kidney donation during the long-term follow-up. We conducted searches of the published literature which included healthy participants, recipients, living kidney donors (LKDs), and the availability of outcome data for malignancy. Eight from 938 potentially relevant studies were analyzed by means of fixed-effects model or random-effects model, as appropriately. In 48,950 participants, the follow-up range was 18 months to 20 years, and the mean age of the subjects was approximately 41 years. The incidence rate with 95% confidence interval (CI) for malignancy after kidney transplantation was 0.03 (0.01-0.05) in recipients and 0.03 (0.1-0.07) in LKDs, giving a pooled incidence rate of 0.03 (95% CI 0.02-0.04). LKDs contrasted nondonors by the overall odds ratio and 95% CI for total cancer of 2.80 (2.69-2.92). Kidney transplantation was associated with an increased risk of cancer during a long-term follow-up. Long-term risk for cancer in LKDs and kidney recipients should be monitored.

    Adoptive immunity is poorly expressed in normal syngeneic mice. This phenomenon was studied by using experimental antituberculosis immunity as a model system representing pure cell-mediated immunity. Expression of adoptive immunity was facilitated by pretreating recipients with sublethal ionizing radiation (500 rads) or high doses (200 mg/kg) of cyclophosphamide or by using adult thymectomized, lethally irradiated, bone-marrow-reconstituted (TXB) mice. Adult thymectomy was less effective, and a low dose of cyclophosphamide (20 mg/kg) was completely ineffective. The beneficial effect of sublethal irradiation was reduced over time; it persisted for 4 weeks and was absent after 8 weeks. Attempts to restore the suppressed state of normal mice to sublethally irradiated mice by using normal spleen or thymus cells did not succeed. Even in rats, which express adoptive antituberculosis immunity without immunosuppressive treatment, the use of sublethally irradiated or TXB recipients potentiated adoptive immunity. It was concluded that suppression of adoptive immunization in normal recipient mice is mediated predominantly, if not exclusively, by T lymphocytes that are sensitive to a number of immunosuppressive agents. The suppressor cells are long-lived and can be regenerated from precursors that are resistant to 500 but not to 900 rads of ionizing radiation

    This paper presents a study of the killer functions of lymph node cells directed against endogenous colony-forming cells in adrenalectomized recipients in a genetic system with one-way incompatibility: parental line - F 1 hybrid. Mice were irradiated with Co 60 gamma rays on the EGO-2 apparatus with dose rate from 200 to 250 R/min. The results were subjected to statistical analysis by Student's test. It can be tentatively suggested that the killer action of T lymphocytes on endogenous colonies was intensified in adrenal-ectomized recipients with endogenous hypocorticism, as a result of cooperation with the cortisol-sensitive subpopulation of T helper cells, of a change in the properties of the antigen-recognizing receptors, or an increase in the sensitivity of target cells to the killer action of T lymphocytes

    Pediatric renal allograft recipients often suffer from osteopenia and the potential for increased fractures. Although modern densitometers are widely available, their use in children is complicated by lack of optimal interpretive criteria. We reviewed dual energy X-ray absorptiometry (DEXA) studies in 33 patients with functional renal allografts 4.4 +/- 3.6 years after transplantation. We interpreted our data using three previously described methods of assigning bone mineral density (BMD) Z scores. BMD was directly related to age, height, weight, body surface area, and pubertal status (p < 0.001). Using gender-mixed reference data matched by chronological age, the mean BMD Z score was -0.9 +/- 1.3 vs. 0.4 +/- 1.4 when matched by height-age (p < 0.001). Height-age adjustment particularly increased the BMD Z score of pubertal adolescents. In a subset of 22 patients, gender-matched reference data led to different results from the gender-mixed reference population (mean BMD Z score 0.0 +/- 1.7 vs. -0.8 +/- 1.4, p < 0.001). The perceived prevalence of osteopenia among pediatric kidney transplant recipients differs using analysis based on chronological age, height-age, or gender-matched reference data. Further studies are necessary to determine the clinical significance of measured bone density in this population.

    Full Text Available Background: Health related quality of life (HRQOL is an important issue for long-term kidney transplantation (KT patients. Nevertheless, few studies have focused on long-term HRQOL in KT recipients with a functional graft. Thus, the aim of this study is to describe the long-term (10-year HRQOL of KT recipients. Methods: This is a cross-sectional and correlational design. The Medical Outcome Survey (MOS SF-36 questionnaire was used to collect data on HRQOL. The data were collected from November 2009 to September 2010 at a medical center in Northern Taiwan. Results: A total of 88 patients were interviewed. The mean years after transplantation was 14.48 (SD = 3.9. The mean score of each of the HRQOL subscales ranged from 59.4 to 82.5. The mean scores on the bodily pain (BP subscale were the highest and, on the general health (GH subscale, the lowest. Compared to the general population, with the exception of the BP subscale, long-term KT patients had a lower mean score (poorer HRQOL on all subscales. Age, gender, serum creatinine level, and employment status were significantly related to HRQOL. Conclusion: HRQOL of long-term KT patients was, overall, poorer than that of the general population. When comparing the HRQOL of KT patients with that of the general population, one should take into account age and gender. Finally, the physical, psychological, and social adjustment domains of HRQOL of KT patients warrant further attention.

    This study sought to explore the impact of care recipient falls on caregivers. Ninety-six community-dwelling caregiver-care recipient dyads participated in a 12-month prospective study. Falls and other accidents and service use were recorded. Dyads were assessed at baseline and after each fall. Assessment included the Zarit Burden Interview and a post-accident survey developed for the present study. Focus groups were then conducted to further explore the impact of falls on caregivers. Fifty-four care recipients (56%) experienced falls within the 12 months of the study. There was a significant increase in caregiver burden after the first fall (Zarit Burden Interview score increased from 24.2±14.2 to 27.6±14.5, Precipient alone. However, there was no increase in the number of services used. Focus group discussions highlighted the need for constant vigilance of the care recipient, a lack of knowledge about support services and concerns related to utilising respite care. Falls among care recipients have a significant impact on carers, including an increased fear of falling, prompting the need for even closer vigilance. WHAT IS KNOWN ABOUT THE TOPIC? Falls are a significant problem for older people as one in three older people fall each year and injurious falls are the leading cause of injury-related hospitalisation in older people. In Australia falls cost the economy over $500 million per year. WHAT DOES THIS PAPER ADD? This paper adds a unique perspective to the falls literature, that of the older person's carer. Falls are a significant problem for community-dwelling carers of older people, contributing to carer burden and impeding the carer's ability to undertake activities of daily living because of the perceived need for constant vigilance to prevent the person they care for from falling. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS? Practitioners should ensure that carers are aware of evidence-based falls-prevention practices and services, such as group and

    Solid-organ transplant recipients may require percutaneous dilational tracheotomy because of prolonged mechanical ventilation or airway issues, but data regarding its safety and effectiveness in solid-organ transplant recipients are scarce. Here, we evaluated the safety, effectiveness, and benefits in terms of lung mechanics, complications, and patient comfort of percutaneous dilational tracheotomy in solid-organ transplant recipients. Medical records from 31 solid-organ transplant recipients (median age of 41.0 years [interquartile range, 18.0-53.0 y]) who underwent percutaneous dilational tracheotomy at our hospital between January 2010 and March 2015 were analyzed, including primary diagnosis, comorbidities, duration of orotracheal intubation and mechanical ventilation, length of intensive care unit and hospital stays, the time interval between transplant to percutaneous dilational tracheotomy, Acute Physiology and Chronic Health Evaluation II score, tracheotomy-related complications, and pulmonary compliance and ratio of partial pressure of arterial oxygen to fraction of inspired oxygen. The median Acute Physiology and Chronic Health Evaluation II score on admission was 24.0 (interquartile range, 18.0-29.0). The median interval from transplant to percutaneous dilational tracheotomy was 105.5 days (interquartile range, 13.0-2165.0 d). The only major complication noted was left-sided pneumothorax in 1 patient. There were no significant differences in ratio of partial pressure of arterial oxygen to fraction of inspired oxygen before and after procedure (170.0 [interquartile range, 102.2-302.0] vs 210.0 [interquartile range, 178.5-345.5]; P = .052). However, pulmonary compliance results preprocedure and postprocedure were significantly different (0.020 L/cm H2O [interquartile range, 0.015-0.030 L/cm H2O] vs 0.030 L/cm H2O [interquartile range, 0.020-0.041 L/cm H2O); P = .001]). Need for sedation significantly decreased after tracheotomy (from 17 patients [54.8%] to

    What are the communicative functions of sad facial expressions? Research shows that people feel sadness in response to losses but it's unclear whether sad expressions function to communicate losses to others and if so, what makes these signals credible. Here we use economic games to test the hypothesis that sad expressions lend credibility to claims of loss. Participants play the role of either a proposer or recipient in a game with a fictional backstory and real monetary payoffs. The proposers view a (fictional) video of the recipient's character displaying either a neutral or sad expression paired with a claim of loss. The proposer then decided how much money to give to the recipient. In three experiments, we test alternative theories by using situations in which the recipient's losses were uncertain (Experiment 1), the recipient's losses were certain (Experiment 2), or the recipient claims failed gains rather than losses (Experiment 3). Overall, we find that participants gave more money to recipients who displayed sad expressions compared to neutral expressions, but only under conditions of uncertain loss. This finding supports the hypothesis that sad expressions function to increase the credibility of claims of loss.

    Soluble fibrinogen-like protein 2 (sfgl2), which is mainly secreted by T cells, is a novel effector of regulatory T cells with immunosuppressive functions. The aim of this study was to investigate serum levels of sfgl2 among renal allograft recipients. From November 2010 to August 2011 we retrospectively divided 47 renal allograft recipients into an acute rejection (n = 19) versus a stable group (n = 28) according to allograft biopsy results, using the Banff 2007 classification. The acute rejection group was subdivided into grade I (n = 8) versus grade II T-cell-mediated (n = 6) or antibody-mediated rejection episodes (n = 5). Peripheral blood samples were collected at the time of biopsy. Fourteen healthy volunteers were included as normal group controls. Serum levels of sfgl2 were analyzed by enzyme-linked immunosorbent assay. Serum levels of sfgl2 were increased among renal allograft recipients suffering from biopsy-proven acute rejection episodes (61.91 ± 45.68 ng/mL), versus those with stable allografts (38.59 ± 19.92 ng/mL, P rejection episodes (41.71 ± 16.44 ng/mL, P rejection (34.10 ± 9.26 ng/mL, P rejection episodes to an extent dependent upon the pathological type and severity of the response.

  2. Vitamin k intake and plasma desphospho-uncarboxylated matrix Gla-protein levels in kidney transplant recipients.

    Paul Y Boxma

    Full Text Available Vitamin K is essential for activation of γ-carboxyglutamate (Gla-proteins including the vascular calcification inhibitor matrix Gla-protein (MGP. Insufficient vitamin K intake leads to production of uncarboxylated, mostly inactive proteins and contributes to an increased cardiovascular risk. In kidney transplant recipients, cardiovascular risk is high but vitamin K intake and status have not been defined. We investigated dietary vitamin K intake, vascular vitamin K status and its determinants in kidney transplant recipients. We estimated vitamin K intake in a cohort of kidney transplant recipients (n = 60 with stable renal function (creatinine clearance 61 [42-77] (median [interquartile range] ml/min, who were 75 [35-188] months after transplantation, using three-day food records and food frequency questionnaires. Vascular vitamin K status was assessed by measuring plasma desphospho-uncarboxylated MGP (dp-ucMGP. Total vitamin K intake was below the recommended level in 50% of patients. Lower vitamin K intake was associated with less consumption of green vegetables (33 vs 40 g/d, p = 0.06 and increased dp-ucMGP levels (621 vs 852 pmol/L, p500 pmol/L in 80% of patients. Multivariate regression identified creatinine clearance, coumarin use, body mass index, high sensitivity-CRP and sodium excretion as independent determinants of dp-ucMGP levels. In a considerable part of the kidney transplant population, vitamin K intake is too low for maximal carboxylation of vascular MGP. The high dp-ucMGP levels may result in an increased risk for arterial calcification. Whether increasing vitamin K intake may have health benefits for kidney transplant recipients should be addressed by future studies.

Two hundred and forty-two adult patients with a functioning graft for at least three months and available data that were followed up on the August 31, 2015 at two transplant centers of Western Greece were included in this study. Baseline recipients' data elements included demographics, clinical characteristics, history of comorbid conditions and laboratory parameters. Follow-up data regarding MACE occurrence were collected retrospectively from the patients' records and MACE risk score was calculated for each patient. The mean age was 53 years (63.6% males) and 47 patients (19.4%) had a pre-existing cardiovascular disease (CVD) before transplantation. The mean estimated glomerular filtration rate was 52 ± 17 mL/min per 1.73 m 2 . During follow-up 36 patients (14.9%) suffered a MACE with a median time to MACE 5 years (interquartile range: 2.2-10 years). Recipients with a MACE compared to recipients without a MACE had a significantly higher mean age (59 years vs 52 years, P Greek database of RTRs was good with an area under the receiver operating characteristics curve of 0.68 (95%CI: 0.58-0.78). In this Greek cohort of RTRs, MACE occurred in 14.9% of the patients, pre-existing CVD was the main risk factor, while MACE risk model was proved a dependable utility in predicting CVD post RT.

  4. Orangutans modify facial displays depending on recipient attention

    Directory of Open Access Journals (Sweden)

    Bridget M. Waller

    2015-03-01

    Full Text Available Primate facial expressions are widely accepted as underpinned by reflexive emotional processes and not under voluntary control. In contrast, other modes of primate communication, especially gestures, are widely accepted as underpinned by intentional, goal-driven cognitive processes. One reason for this distinction is that production of primate gestures is often sensitive to the attentional state of the recipient, a phenomenon used as one of the key behavioural criteria for identifying intentionality in signal production. The reasoning is that modifying/producing a signal when a potential recipient is looking could demonstrate that the sender intends to communicate with them. Here, we show that the production of a primate facial expression can also be sensitive to the attention of the play partner. Using the orangutan (Pongo pygmaeus Facial Action Coding System (OrangFACS, we demonstrate that facial movements are more intense and more complex when recipient attention is directed towards the sender. Therefore, production of the playface is not an automated response to play (or simply a play behaviour itself and is instead produced flexibly depending on the context. If sensitivity to attentional stance is a good indicator of intentionality, we must also conclude that the orangutan playface is intentionally produced. However, a number of alternative, lower level interpretations for flexible production of signals in response to the attention of another are discussed. As intentionality is a key feature of human language, claims of intentional communication in related primate species are powerful drivers in language evolution debates, and thus caution in identifying intentionality is important.

  5. Recipients of major scientific awards: A descriptive and predictive analysis

    Barbee, Andrew Calvin

    Recent trends demonstrate an increase of women in leadership roles, STEM fields, and participating in higher education including graduate and doctoral programs, which is a result of Title IX. This quantitative study considered major scientific awards awarded to females and examines demographic characteristics of awardees from the Nobel, National Academy of Sciences (NAS), and National Science Foundation (NSF). More specifically, the following awards were examined the Nobel Prize in Chemistry, the NAS Public Welfare Medal, and the NSF National Medal of Science within the discipline of Physical Science. Also, this study focused on equality to determine if a fair playing field and equal opportunity for women in academics has improved since Title IX. A limited amount of research has explored female award recipients. Specifically, existing research, has not examined the pinnacle of academic performance in the form of national and international awards. In the present study, I posed research questions relating to demographic characteristics of award recipients from the Nobel, NAS, and NSF between 1975 and 2015. Additionally, I examined if sex and age of the awardees could predict early career award obtainment. Through the frame of Social cognitive theory (Bandura, 1986, 1997, and 2005) I considered how perceptions of gender roles are a product of influence by society and the possible connection to performance. Results indicated a limited number of females have received these scientific awards and the awardees age could predict receiving an award early in their career. Additionally, the study provided insight into the progression of Title IX within the context of athletics and academics. It addressed the incremental and systematic increase in academics for women at high school, college, career, and scientific awards. Perhaps most importantly, it identified an observed pattern for female science award recipients reaching a critical mass and a tipping point.

    Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients. Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1μg/day). Serum concentrations and gene expression levels of inflammatory cytokines in peripheral blood mononuclear cells were analysed at the beginning and end of the study. Paricalcitol significantly decreased parathyroid hormone levels with no changes in calcium and phosphorous. It also reduced serum concentrations of interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) by 29% (P<0.05) and 9.5% (P<0.05) compared to baseline, respectively. Furthermore, gene expression levels of IL-6 and TNF-α in peripheral blood mononuclear cells decreased by 14.1% (P<0.001) and 34.1% (P<0.001), respectively. The ratios between pro-inflammatory cytokines (TNF-α and IL-6) and anti-inflammatory cytokines (IL-10), both regarding serum concentrations and gene expression, also experienced a significant reduction. Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits.

    The proportion of elderly kidney transplant candidates is increasing worldwide due to higher number of patients with end-stage renal disease in aging societies. Accordingly, organ allocation policies in this population were adjusted in several countries. The European Senior Program is the most prominent example, where elderly patients (≥65years) receive elderly (≥65years) donor organs with acceptable results. Because of age-dependent changes in the immune response and higher susceptibility to immunosuppressant side effects, outcomes in elderly patients are different compared to younger kidney transplant recipients. However, elderly patients do reject, especially poorly matched elderly donor organs. This warrants tailored immunosuppressive regimes with regard to the age-related changes of the immune system. Rejection therapies may have detrimental side effects in the seniors and are frequently leading to over-immunosuppression (malignancy and infections) in long-term therapy. It is hypothesized that after initial graft adaptation elderly patients may benefit from less immunosuppression in order to lower cancer risk and reduce infection rates and cardiovascular comorbidities. Current evidence on recommended standard immunosuppressive therapy was mainly derived from trials, where elderly patients were excluded or only a minority. In order to improve immunosuppressive therapy in elderly transplant recipients, current immunosuppressive regimes have to be re-investigated in this growing population. Up to date, only a few well-designed prospective studies were performed in elderly populations and demonstrate the need for effective immunosuppression in the first months after transplantation. It is evident that novel treatment strategies and adequately powered prospective clinical trials are needed to establish time-adapted immunosuppressive regimens according to the needs of this vulnerable group of kidney transplant recipients.

    Lamivudine has been shown to prevent de novo hepatitis B virus (HBV) infections in liver transplantation (LT) patients receiving hepatitis B core antibody-positive (HBcAb(+)) grafts, but it may produce long-term resistance. Adefovir dipivoxil (ADV) might be effective in preventing de novo hepatitis and resistance. A single-center, prospective trial was conducted with 16 adults (10 men and 6 women, mean age = 54 ± 11 years) who underwent LT with HBcAb(+) grafts between September 2007 and October 2009. After LT, patients were given ADV [10 mg daily (adjusted for renal function)]. No hepatitis B immune globulin was administered. At LT, all graft recipients were hepatitis B surface antigen-negative (HBsAg(-)), 38% were surface antibody-positive (HBsAb(+)), and 50% were HBcAb(+). The median follow-up after LT was 1.8 years (range = 1.0-2.6 years). All recipients had undetectable HBV DNA (HBcAb(-) before LT became HBsAg(+) after 52 weeks. One recipient was switched from ADV to entecavir for chronic renal insufficiency, and 19% of the patients had renal dose adjustments. There was a nonsignificant trend of increasing creatinine levels over time (1.2 mg/dL at LT, 1.3 mg/dL 1 year after LT, and 2.0 mg/dL 2 years after LT, P = 0.27). A comparison with a control cohort of LT recipients with hepatitis C virus who did not receive ADV showed no difference in the creatinine levels at LT or 1 year after LT. In conclusion, ADV prophylaxis prevents HBV replication in recipients of HBcAb(+) livers but does not fully protect recipients from de novo HBV. Long-term follow-up is needed to better determine the risk of de novo infection. Copyright © 2012 American Association for the Study of Liver Diseases.

    Full Text Available Amoebic liver abscess (ALA is by far the most common extraintestinal manifestation of invasive amoebiasis. The vast majority of these resolve with treatment; however, a small percentage of the treated ALAs are known to persist asymptomatically. Herein, we present a prospective renal allograft recipient with a residual liver abscess who had a successful renal transplant after treatment. In our opinion, persistence of a radiological finding of residual abscess in the absence of clinical disease does not appear to be a contraindication to renal transplantation.

    Full Text Available Urinary tract infections (UTI are the most common bacterial infections after renal transplantation and are associated with significant morbidity and mortality. Recurrent or relapsing infections are not uncommon in the early post-transplant period and superadded fungal UTI can occur in these patients, posing a difficult therapeutic problem. Literature on recurrent UTI after transplant as well as the ideal approach to such patients is scanty. We present the case of a renal al-lograft recipient who presented with relapsing bacterial UTI complicated by systemic fungemia; also, a brief review of fungal UTI is attempted.

    Full Text Available Case histories of 2 renal transplant recipients are reported who had presenting features of fever, leukocytosis and pain/tenderness over right iliac fossa and were diagnosed to be due to acute appendicitis rather than more commonly suspected acute rejection episode which has very similar features. Diagnosis of acute appendicitis was suspected on the basis of rectal examination and later confirmed by laparotomy. The purpose of this communication is to emphasize the need for proper diagnosis in patient with such presentation; otherwise wrong treatment may be received.

    Mycobacterium avium-intracellulare complex (MAC) infections are well known in immunocompromised patients, notably in human immunodeficiency virus infection, but remain scarcely described in kidney transplantation. Moreover, cutaneous involvement in this infection is very unusual. We describe here a disseminated infection caused by MAC in a kidney transplant recipient revealed by cutaneous lesions. This case highlights the need for an exhaustive, iterative microbiologic workup in the context of an atypical disease presentation in a renal transplant patient, regardless of the degree of immunosuppression. © 2015 John Wiley & Sons A/S.

    2016-02-01

    Full Text Available We report a case of a 66-year-old diabetic patient who presented with muscle weakness 2 weeks after kidney transplantation. Her immunosuppressive regimen included tacrolimus, mycophenolate mofetil, and steroids. She was found to have hyperkalemia and normal anion gap metabolic acidosis. Tacrolimus levels were in therapeutic range. All other drugs such as beta blockers and trimethoprim – sulfamethoxazole were stopped. She did not respond to routine antikalemic measures. Further evaluation revealed type 4 renal tubular acidosis. Serum potassium levels returned to normal after starting sodium bicarbonate and fludrocortisone therapy. Though hyperkalemia is common in kidney transplant recipients, determining exact cause can guide specific treatment.

  16. [Relative weight of the recipient's benefits and the donor's costs in determining the magnitude of indebtedness].

    Aikawa, A

    1988-02-01

    Greenberg (1980) proposed that the magnitude of indebtedness (I) was a function of the recipient's benefits (B) from the aid attempt plus the donor's costs (C). This relationship is expressed by the equation I = x1B + x2C, x1 greater than x2, where x1 and x2 are empirically determined weights. The present study examined the validity of this equation. The subjects, 272 university students, were asked to place themselves in the role of a hypothetical student confronted with each of 32 different situations in which the student needed some aid from others, and to answer a series of questions regarding their reactions. A multiple regression analysis validated the equation in 23 out of the 32 situations. In situations in which the outcome of the aid attempt was successful with low cost for the donor, there was a tendency for the subjects to estimate x1 to be smaller than x2(x1 less than x2).

    Telomeres are noncoding DNA regions at the end of the chromosomes that are crucial for genome stability. Since telomere length decreases with cell division, they can be used as a signature of cell proliferation history. T-cell reconstitution in severe combined immunodeficiency (SCID) subjects, recipients of T-cell-depleted, allogeneic-related bone marrow cells, is due to the development and maturation of donor T-cell precursors in the infant's vestigial thymus and to homeostatic proliferation of mature T cells in the peripheral organs. Since T-cell function, thymic output, and T-cell clonal diversity are maintained long term in these patients, we investigated whether donor T-cell engraftment resulted in increased telomere shortening. Our study of seven SCID patients, following successful bone marrow transplantation, demonstrates that the patients' peripheral T cells did not exhibit greater than normal telomere shortening.

    Gastroduodenal ulcers in renal transplant recipients are usually originated from excessive acid secretion or infection of Helicobacter pyroli. Herein, we report a case of cytomegalovirus (CMV)--induced gastric ulcer following cadaveric renal transplantation. The patient was a 48-year-old man with chronic renal failure and received cadaveric renal transplantation. A month later, he had epigastralgia without CMV-positive antigenemia and received gastrointestinal fiberscopy. Endoscopically, gastric ulcer was identified. Histological findings revealed conspicious nuclear enlargement of the non-epithelial cells in the ulcer bed, which indicated CMV infection. The patient was treated with ganciclovir for 2 weeks and the symptom was relieved. He discharged with a good renal function on day 75 posttransplant. CMV infection plays an important role in gastric ulcer after renal transplantation. Antigenemia assay dose not seem feasible for the detection of CMV-induced gastric ulcer.

    The aim of this study was to evaluate the possible contribution of 3 He-MRI to detect obliterative bronchiolitis (OB) in the follow-up of lung transplant recipients. Nine single- and double-lung transplanted patients were studied by an initial and a follow-up 3 He-MRI study. Images were evaluated subjectively by estimation of ventilation defect area and quantitatively by individually adapted threshold segmentation and subsequent calculation of ventilated lung volume. Bronchiolitis obliterans syndrome (BOS) was diagnosed using pulmonary function tests. At 3 He-MRI, OB was suspected if ventilated lung volume had decreased by 10% or more at the follow-up MRI study compared with the initial study. General accordance between pulmonary function testing and 3 He-MRI was good, although subjective evaluation of 3 He-MRI underestimated improvement in ventilation as obtained by pulmonary function tests. The 3 He-MRI indicated OB in 6 cases. According to pulmonary function tests, BOS was diagnosed in 5 cases. All diagnoses of BOS were also detected by 3 He-MRI. In 2 of these 5 cases, 3 He-MRI indicated OB earlier than pulmonary function tests. The results support the hypothesis that 3 He-MRI may be sensitive for early detection of OB and emphasize the need for larger prospective follow-up studies. (orig.)

  1. Phosphocalcic Markers and Calcification Propensity for Assessment of Interstitial Fibrosis and Vascular Lesions in Kidney Allograft Recipients.

    Full Text Available Renal interstitial fibrosis and arterial lesions predict loss of function in chronic kidney disease. Noninvasive estimation of interstitial fibrosis and vascular lesions is currently not available. The aim of the study was to determine whether phosphocalcic markers are associated with, and can predict, renal chronic histological changes. We included 129 kidney allograft recipients with an available transplant biopsy in a retrospective study. We analyzed the associations and predictive values of phosphocalcic markers and serum calcification propensity (T50 for chronic histological changes (interstitial fibrosis and vascular lesions. PTH, T50 and vitamin D levels were independently associated to interstitial fibrosis. PTH elevation was associated with increasing interstitial fibrosis severity (r = 0.29, p = 0.001, while T50 and vitamin D were protective (r = -0.20, p = 0.025 and r = -0.23, p = 0.009 respectively. On the contrary, fibroblast growth factor 23 (FGF23 and Klotho correlated only modestly with interstitial fibrosis (p = 0.045 whereas calcium and phosphate did not. PTH, vitamin D and T50 were predictors of extensive fibrosis (AUC: 0.73, 0.72 and 0.68 respectively, but did not add to renal function prediction. PTH, FGF23 and T50 were modestly predictive of low fibrosis (AUC: 0.63, 0.63 and 0.61 but did not add to renal function prediction. T50 decreased with increasing arterial lesions (r = -0.21, p = 0.038. The discriminative performance of T50 in predicting significant vascular lesions was modest (AUC 0.61. In summary, we demonstrated that PTH, vitamin D and T50 are associated to interstitial fibrosis and vascular lesions in kidney allograft recipients independently of renal function. Despite these associations, mineral metabolism indices do not show superiority or additive value to fibrosis prediction by eGFR and proteinuria in kidney allograft recipients, except for vascular lesions where T50 could be of relevance.

    BACKGROUND Graft-site candidiasis rarely develops in solid organ transplant recipients; however, severe life-threatening complications can occur. We report the course of 3 solid organ transplant recipients developing graft-site candidiasis. CASE REPORT All grafts, consisting of 2 kidneys and 1 liver, were procured from a single donor. Patient data were collected from our database. Candida albicans was isolated from a swab taken during multiple-organ recovery. Complications associated with candidiasis occurred in all 3 recipients with preservation of the liver transplant. Both renal transplant recipients had vascular complications, eventually resulting in graft nephrectomy and subsequent return to dialysis. The patients recovered completely without residual effects of their prior fungal infection. CONCLUSIONS Fungal infections in solid organ transplant recipients are rare. Since the sequelae of these infections are serious and usually pertain to more than 1 recipient at a time, antifungal prophylaxis may be warranted in select donors.

    The results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 ± 4.1 vs. 24.3 ± 3.7; P mismatch was associated with mortality in men (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.06-1.32; P = 0.003) but not in women (HR, 0.91; 95% CI 0.74-1.12; P = 0.4). A significant interaction was detected between sex mismatch and recipient gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with long-term mortality (HR, 1.14; 95% CI 1.01-1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women. © 2014 Steunstichting ESOT.

    Nocardia infections are an uncommon but important cause of morbidity and mortality in renal transplant recipients. The present study was carried out to determine the spectrum of Nocardia infections in a renal transplant centre in Australia. A retrospective chart analysis of all renal transplants performed from 2008 to 2014 was conducted to identify cases of culture proven Nocardia infection. The clinical course for each patient with nocardiosis was examined. Four of the 543 renal transplants patients developed Nocardia infection within 2 to 13 months post-transplant. All patients were judged at high immunological risk of rejection pre-transplant and had received multiple sessions of plasmaphoeresis and intravenous immunoglobulin before the onset of the infection. Two patients presented with pulmonary nocardiosis and two with cerebral abscesses. One case of pulmonary nocardiosis was complicated by pulmonary aspergillosis and the other by cytomegalovirus pneumonia. All four patients improved with combination antibiotic therapy guided by drug susceptibility testing. At the time of Nocardia infection all four patients were receiving primary prophylaxis with trimethoprim/sulphamethoxazole (TMP/SMX) 160/800 mg, twice weekly. Plasmaphoeresis may be risk factor for Nocardia infection and need further study. Nocardia infection may coexist with other opportunistic infections. Identification of the Nocardia species and drug susceptibility testing is essential in guiding the effective management of patients with Nocardia. Intermittent TMP-SMX (one double strength tablet, twice a week) appears insufficient to prevent Nocardia infection in renal transplant recipients. © 2015 Asian Pacific Society of Nephrology.

    Leukopenia is frequently observed in the setting of solid organ transplantation. The risk factors, natural history, and outcomes associated with leukopenia post-transplantation have not been well defined. We retrospectively studied 102 adult kidney and/or pancreas transplant recipients over a one-yr period of time. By defining leukopenia as a white blood cell count leukopenia or neutropenia was 58% (59/102); the first episode occurred at a mean of 91 d post-transplant. A significant increase in the incidence of leukopenia was found in patients who either received alemtuzumab induction (42% with alemtuzumab vs. 9% with rabbit anti-thymocyte globulin induction, p leukopenia was reducing the dose of mycophenolate mofetil and/or valganciclovir. When granulocyte stimulating factors were used, a mean of 3.1 doses were needed to successfully manage the leukopenia. Although leukopenia was a common finding in our study of kidney and/or pancreas transplant recipients, there was no difference in the rates of infection or acute rejection in patients with and without leukopenia.

  6. Cutaneous Squamous Cell Carcinomas in Organ Transplant Recipients

    Full Text Available Non-melanoma skin cancers represent a major cause of morbidity after organ transplantation. Squamous cell carcinomas (SCC are the most common cutaneous malignancies seen in this population, with a 65–100 fold greater incidence in organ transplant recipients compared to the general population. In recent years, human papillomaviruses (HPV of the beta genus have been implicated in the pathogenesis of post-transplant SCCs. The underlying mechanism of carcinogenesis has been attributed to the E6 and E7 proteins of HPV. Specific immunosuppressive medications, such as the calcineurin inhibitors and azathioprine, are associated with a higher incidence of post-transplant SCCs compared to other immunosuppressive agents. Compared to other immunosuppressives, mTOR inhibitors and mycophenolate mofetil have been associated with a decreased risk of developing post-transplant non-melanoma skin cancers. As a result, they may represent ideal immunosuppressive medications in organ transplant recipients. Treatment options for post-transplant SCCs include surgical excision, Mohs micrographic surgery, systemic retinoid therapy, adjunct topical therapy, electrodessication and curettage, and radiation therapy. This review will discuss the epidemiology, risk factors, and management options of post-transplant SCCs. In addition, the underlying mechanisms of beta-HPV mediated carcinogenesis will be discussed.

    Full Text Available Renal transplantation is considered the best treatment option for patients with end-stage renal disease. In this study, the prevalence of oral lesions was studied in a cohort of renal transplant recipients before and after transplantation. Fifty-nine kidney transplant recipients were examined one week before and four months after transplantation. The information gathered included age, sex, smoking history, duration on dialysis, drugs and their doses. There were 41 males (69.5% and 18 females (30.5% with a mean age of 37 years. Before surgery, two patients had non-specific lesions and two other patients had leukoedema. Following transplantation, 24 patients (40.7% did not have any specific lesion. In six patients, we observed non-specific erythematous lesions (10.2%. Other recorded observations are as follows: Gingival hyperplasia in five patients (8.5%, oral candidiasis of the erythematous type in five patients (8.5%, hairy leukoplakia in four patients (6.8% and leukoedema in seven patients (11.9%. In our study patients, the prevalence of oral lesions increased after transplantation, although it was lower than that reported in other studies. This could be due to the differences in sample size, differences between Iranian race and other races and different pharmaceutical formulation of the drug produced in Iran.

  8. Adherence in pediatric kidney transplant recipients: solutions for the system.

    Steinberg, Elizabeth A; Moss, Mary; Buchanan, Cindy L; Goebel, Jens

    2018-03-01

    Non-adherence remains a significant problem among pediatric (and adult) renal transplant recipients. Non-adherence among solid organ transplant recipients results in US$15-100 million annual costs. Estimates of non-adherence range from 30 to 70% among pediatric patients. Research demonstrates that a 10% decrement in adherence is associated with 8% higher hazard of graft failure and mortality. Focus has begun to shift from patient factors that impact adherence to the contributing healthcare and systems factors. The purpose of this review is to describe problems within the systems implicated in non-adherence and potential solutions that may be related to positive adherence outcomes. Systems issues include insurance and legal regulations, provider and care team barriers to optimal care, and difficulties with transitioning to adult care. Potential solutions include recognition of how systems can work together to improve patient outcomes through improvements in insurance programs, a multi-disciplinary care team approach, evidence-based medical management, pharmacy-based applications and interventions to simplify medication regimens, improved transition protocols, and telehealth/technology-based multi-component interventions. However, there remains a significant lack of reliability in the application of these potential solutions to systems issues that impact patient adherence. Future efforts should accordingly focus on these efforts, likely by leveraging quality improvement and related principles, and on the investigation of the efficacy of these interventions to improve adherence and graft outcomes.

    Kidney transplantation is the renal replacement therapy of choice for most patients with end-stage renal disease (ESRD), however, adherence to the recommended lifestyle is critical for a positive prognosis. The purpose of this study was to assess adherence to immunosuppressive therapy and lifestyle recommendations along with some related factors among kidney transplant patients. In this descriptive analytical study, all patients completed a questionnaire regarding medication intake and lifestyle recommendations (preventing of infection, self-monitoring, prevention of cardiovascular disease (CVD), and sun protection). The participants were divided into 4 groups according to the level of adherence (good, partial, poor, and nonadherent) indicated in their responses. Most kidney recipients were adherent to their drug prescriptions, but were partial, poor, or nonadherent regarding lifestyle recommendations. Increased passage of time since transplantation and low family support and educational level resulted in nonadherence. Men showed greater adherence to medication intake than women. Patients with lower number of drugs and reported drug side-effects illustrated better adherence to medication intake. Women adhered to infection protection recommendations more than men, and older and married patients adhered to cardiovascular prevention recommendations more than others. However, younger patients showed greater adherence to self-monitoring recommendations, and singles, young individuals, and women were adherent to sun protection recommendations. Nonadherence is common among kidney transplant recipients. Thus, it is necessary to determine patients who are at risk of nonadherence and to introduce more educational programs to improve their adherence and their quality of life (QOL).

    Clostridium difficile infection (CDI) is a major healthcare-associated infection that causes significant morbidity and an economic impact in the United States. In this review, we provide an overview of Clostridium difficile infection in solid organ transplant recipients with an emphasis on recent literature. C. difficile in solid organ transplant population has unique risk factors. Fecal microbiota transplantation has shown favorable results in treatment of recurrent C. difficile in this population. Preliminary data from animal studies suggests excellent efficacy with immunization against C. difficile toxins. Over the last decade, number of individuals receiving solid organ transplants has increased exponentially making peri-transplant complications a common occurrence.C. difficile is a frequent cause of morbidity in solid organ transplant recipients. Early and accurate diagnosis of C. difficile requires a stepwise approach. Differentiating between asymptomatic carriage and infection is a diagnostic challenge. Microbial diversity is inversely proportional to risk of C. difficile infection. Antimicrobial stewardship programs help to retain microbial diversity in individuals susceptible to CDI. Recurrent or relapsing C. difficile infection require fecal microbiota transplantation for definitive cure.

    Candidacy for liver transplantation is determined through standardized evaluation. There are limited data on the frequency and reasons for denial of transplantation after assessment; analysis may shed light on the short-term utility of the assessment. We sought to describe the frequency and reasons for ineligibility for liver transplantation among referred adults. We studied all prospectively followed recipient candidates at a single centre who were deemed unsuitable for liver transplantation after assessment. Inclusion criteria were age 18 years and older and completion of a standard liver transplantation evaluation over a 3-year period. Patients were excluded if they had a history of prior assessment or liver transplantation within the study period. Demographic and baseline clinical data and reasons for recipient ineligibility were recorded. In all, 337 patients underwent their first liver transplantation evaluation during the study period; 166 (49.3%) fulfilled inclusion criteria. The mean age was 55.4 years, and 106 (63.9%) were men. The 3 most common reasons for denial of listing were patient too well (n = 82, 49.4%), medical comorbidities and/or need for medical optimization (n = 43, 25.9%) and need for addiction rehabilitation (n = 28, 16.9%). Ineligibility for transplantation after assessment was common, occurring in nearly half of the cohort. Most denied candidates could be identified with more discriminate screening before the resource-intensive assessment; however, the assessment likely provides unforeseen positive impacts on patient care.

    OBJECTIVE: To report the pregnancy outcomes in Irish female renal transplant recipients on modern maintenance immunosuppression. METHODS: The Republic of Ireland transplant database was accessed to identify the patient cohort in question. All female renal transplant recipients whose transplantation was in Ireland before or during their reproductive years were included. A questionnaire was sent to the identified women. A chart review was performed for those women who reported a pregnancy following renal transplantation. RESULTS: Two hundred and ten women met the inclusion criteria. There was a response rate of 70% (n = 148). Eighteen women reported 29 pregnancies. The live birth rate was 76%. The mean gestation of the live births was 36.2 weeks with a mean birth weight of 3.0 kg. There were six cases of pre-eclampsia. Twin pregnancies and those entering pregnancy with a creatinine greater than 135 micromol\\/l had particularly complicated clinical courses. Four women had not conceived post transplant despite actively trying for over 1 year. Two women utilised assisted fertility methods (in vitro fertilisation), one of whom became pregnant. CONCLUSIONS: A significant proportion of women who attempt to conceive following renal transplantation are successful, without the use of assisted fertility. Pregnancy in this setting warrants meticulous multidisciplinary care.

    Many studies have documented the increased risk of non-melanoma skin cancers in organ transplant recipients (OTRs). However, the incidence of melanoma is less well defined. To date, there have been no studies on the incidence of melanoma in Canadian OTRs. Herein, we determine the incidence and clinical features of melanoma in a cohort of OTRs in Southern Alberta, Canada. We used the Southern Alberta Transplant database to identify kidney and liver transplant recipients between the years 2000 and 2012. This population was cross-referenced with the Alberta Cancer Registry for a diagnosis of melanoma. The clinical features of all cases were obtained, and the standardized incidence rate was calculated. We identified 993 OTR patients, representing 5955 person-years. Only one patient developed a melanoma post-transplant, and this was a nodular melanoma. The age-standardized incidence rate was 11 per 100 000 (0.6 per 5955), compared to 13.4 per 100 000 in the general Alberta population (incidence rate ratio of 1.29, with 95% confidence interval of 0.17 to 9.82). This is the first Canadian study to investigate the association between organ transplantation and melanoma. Our study did not identify an increased risk of developing a de novo melanoma post-transplant. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We investigated magnesium excretion and rate of hypomagnesemia in pediatric renal transplant recipients. The medical records of 114 pediatric renal transplant recipients were retrospectively evaluated. After exclusion of 23 patients, 91 patients were included in the study. We recorded serum magnesium levels at the time of measurement of urine magnesium wasting. Mean serum magnesium levels were 1.73 ± 0.22 mg/dL and 38 of the patients (41%) had hypomagnesemia. There was a negative correlation between serum magnesium levels and estimated glomerular filtration rate and serum tacrolimus trough level (r=-0.215, p=0.040 and r=-0.409, p=0.000, respectively). Also, there was a statistically significant positive correlation between serum magnesium levels and transplantation duration (r=0.249, p=0.017). Mean fractional magnesium excretion was 5.9 ± 3.7% and 59 patients (65%) had high magnesium excretion. There was a significant negative correlation between fractional magnesium excretion and estimated glomerular filtration rate (r=-0.432, p=0.001). There was a significant positive correlation between fractional magnesium excretion and serum creatinine (r=0.379 p=0.003). Patients with higher tacrolimus trough blood levels, lower glomerular filtration rate and at early posttransplant period had risk of hypomagnesemia.

    Music perception and appraisal are generally poor in cochlear implant recipients. Simple musical structures, lyrics that are easy to follow, and clear rhythm/beat have been reported among the top factors to enhance music enjoyment. The present study investigated the preference for modified relative instrument levels in music with normal-hearing and cochlear implant subjects. In experiment 1, test subjects were given a mixing console and multi-track recordings to determine their most enjoyable audio mix. In experiment 2, a preference rating experiment based on the preferred relative level settings in experiment 1 was performed. Experiment 1 was performed with four postlingually deafened cochlear implant subjects, experiment 2 with ten normal-hearing and ten cochlear implant subjects. A significant difference in preference rating was found between normal-hearing and cochlear implant subjects. The latter preferred an audio mix with larger vocals-to-instruments ratio. In addition, given an audio mix with clear vocals and attenuated instruments, cochlear implant subjects preferred the bass/drum track to be louder than the other instrument tracks. The original audio mix in real-world music might not be suitable for cochlear implant recipients. Modifying the relative instrument level settings potentially improves music enjoyment.

    GJB2, SLC26A4 (PDS) and mitochondrial DNA (mtDNA) have been associated with sensorineural hearing loss. In the present study, the clinical, genetic and molecular analysis of 14 cochlear implant recipients and their parents was studied from April 2006 to September 2007. Of the 14 subjects, 35.7% had gene mutations; 28.6% had homozygous GJB2 235delC mutation, whose parents carried heterozygous GJB2 235delC mutation; and 7.1% had mtDNA A1555G mutation, whose mother carried mtDNA A1555G mutation too. There was no SLC26A4 (PDS) mutation. These results strongly suggested that the mutation in GJB2 gene was a major cause of deafness in cochlear implant recipients and the mutation of mtDNA A1555G was another important cause. Genetic test of hot-spots and analysis of family constellation can offer an accurate genetic counseling to deaf family and reduce the incidence of hearing loss.

    It has been suggested that co-transferring parthenogenetic embryos could improve the pregnancy success rate with cloned embryos in mammals. As an alternative to co-transferring parthenotes, in dogs we employed recipient females that possessed in vivo-fertilised embryos as a result of mating to determine whether mated bitches could be suitable recipients for cloned embryos. The effect of using mated recipients on implantation and pregnancy rates of canine somatic cell nuclear transfer embryos was also determined. Cloned embryos were transferred into the oviducts of naturally synchronous females that had mated with male dogs before ovulation. The pregnancy rate appeared to be similar between mated recipients (50%) and non-mated recipients (28.57%; P>0.05). However, the delivery rate of cloned pups was significantly higher in mated recipients than non-mated recipients (10.53 vs 2.38%; Pcloned pups in non-mated recipients were delivered by Caesarean section because the fall in progesterone concentration in these females did not occur until the due date. The present study demonstrated for the first time that mated female dogs can be used as recipients for cloned embryos.

    Full Text Available Donation after cardiac death (DCD has expanded in the last decade in the US; however, DCD liver utilization has flattened in recent years due to poor outcomes. We examined clinical and quality of life (QOL outcomes of DCD recipients by conducting a retrospective and cross-sectional review of patients from 2003 to 2010. We compared clinical outcomes of DCD recipients (n=60 to those of donation after brain death (DBD liver recipients (n=669 during the same time period. DCD recipients had significantly lower rates of 5-year graft survival (P<0.001 and a trend toward lower rates of 5-year patient survival (P=0.064 when compared to the DBD cohort. In order to examine QOL outcomes in our cohorts, we administered the Short Form Liver Disease Quality of Life questionnaire to 30 DCD and 60 DBD recipients. The DCD recipients reported lower generic and liver-specific QOL. We further stratified the DCD cohort by the presence of ischemic cholangiopathy (IC. Patients with IC reported lower QOL when compared to DBD recipients and those DCD recipients without IC (P<0.05. While the results are consistent with clinical experience, this is the first report of QOL in DCD recipients using standardized measures. These data can be used to guide future comparative effectiveness studies.

    Dyslipidemia occurs in approximately 70% of all liver transplant (LT) recipients, and no prior control studies have demonstrated any dietary intervention to change it. To analyze the effects of a dietary intervention on the lipid profile of dyslipidemic LT recipients. All LT recipients with dyslipidemia on clinical follow-up were enrolled. Anthropometric evaluation, food history, body composition (bioimpedance) and assessment of basal metabolism through indirect calorimetry were performed. Patients met with a dietitian and an individualized diet based on estimate of basal metabolism and consisting of 25% of the total energy value in total fat and basal metabolism through indirect calorimetry was able to manage dyslipidemia in most LT recipients; so, all dyslipidemic LT recipients must be enrolled on a dietary program.

    As of September 19, 2014, 2441 cases of intestinal transplantation have been performed in 46 centers (2400 deceased, 41 living). Eight centers did more than 100 transplants. Annual case numbers peaked in 2007 (N = 198) and steadily decreased to 109 cases in 2013. Short gut syndrome (68%) and functional bowel problems (15%) are two major indications for intestinal transplantation. The 3 major types of transplants involving the intestine include: isolated intestine transplant (I); simultaneous intestine, liver, and pancreas transplant (I+L+P); and, combined intestine and liver (I+L) transplant. Graft survival has significantly improved in recent years, mainly due to improved first year graft survival. The 1-, 5-, and 10-year graft survivals were: 74%, 42%,and 26%, respectively (I); 70%, 50%, and 40%, respectively (I+L+P); and 61%, 46%, and 40%, respectively (I+L). The longest graft survivals for I, l+L+P, and l+L were 19 years, 16 years, and 23 years, respectively. Steroids, Thymoglobulin, and rituximab are 3 major induction agents used in recent years. Prograf, steroids, and Cellcept are 3 major maintenance agents. Induction recipients (68% of all patients) had a significantly lower acute rejection rate than nonrecipients before discharge (60% versus 75%, p transplants, while 6% (N = 29) received ABO compatible transplants. ABO identical transplant recipients had a significantly higher 5-year graft survival rate than ABO compatible recipients (39% versus 21%, p transplants were lower than those of ABO identical transplants. However, the difference did not reach statistical significance (46% versus 49%, p = 0.07). The effect of ABO compatibility on graft outcome was further confirmed by Cox Analysis. ABO incompatible transplants are still rarely performed (N = 4) in intestine. In conclusion, annual case numbers of intestinal transplants have been decreasing, regardless of improved graft survival. ABO compatible intestinal transplants previously had a significantly

    The shortage of organs is a major hurdle in kidney transplantation, and one solution to the problem is to extend the age of the donor. However, organs from older donors are often discarded due to the macroscopic appearance of the parenchyma or major vessels. On the other hand, a large number of elderly patients are potential candidates for kidney transplantation, while many kidneys from elderly deceased donors are discarded due to a lack of age-matched recipients. In addition, a large number are often discarded due to the lack of compatible recipients among elderly patients undergoing chronic dialysis. A possible solution to avoid this wastage of kidneys potentially suitable for transplantation could be the performance of preemptive kidney transplantation (PKT) in carefully selected elderly patients. PKT improves graft and patient survival compared to other renal replacement therapy options. There is no information about PKT in elderly patients receiving kidneys from elderly deceased donors. From 2007 to 2012, we performed a prospective observational study comparing 26 elderly patients receiving PKT with a control group of 26 elderly patients receiving a first transplant after prior dialysis. Mean age of recipients was 74.3±2.9 years and mean age of donors was 73.8±4.1 years. Induction immunosuppression was similar in both groups. Death-censored graft survival was 96% in the PKT group and 68% in the control group (p=0.02), at 5 years after transplantation. Immediate and delayed graft function occurred in 92% and 3.8%, respectively, of patients in the PKT group and 53% and 34.6% of patients in the control group (p=0.005). Acute rejection was significantly more frequent in PKT patients (23.1% vs 3.8%, p=0.043). At the end of follow-up time 35.5±20.1 months, the glomerular filtration rate was similar in both groups (42.2±11.7 vs 41.7±11.2ml/min, p-value=0.72). Patient survival was similar in the two groups.

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

    A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder in adult recipients of solid organ transplants. This review details the therapeutic options recommended including reduction in immunosuppression (RIS), transplant organ resection, radiotherapy and chemotherapy. Effective therapy should be instituted before progressive disease results in declining performance status and multi-organ dysfunction. The goal of treatment should be a durable complete remission with retention of transplanted organ function with minimal toxicity.

    The aim of this study was to investigate the relationship between donor-to-recipient weight ratio and post-transplantation survival. From February 1988 to November 2006, 255 adult bilateral lung transplantation patients from 2 different centers were retrospectively analyzed. The cohort was divided into 4 groups depending on the quartile ranges of the donor-to-recipient weight ratio. A time-to-event analysis was performed for risk of death after transplantation conditional on 5-year survival using Kaplan-Meier and Cox proportional hazards models. The mean weight ratio for the study cohort was 1.23 ± 0.39. For all lung transplant recipients during the study period, survival rate at 5 years was 58%. Median survival was 6.3 years in the cohort subgroup with weight ratio ratio >1.23. Weight ratio >1.23 recipients had a significant survival advantage out to 5 years compared with weight ratio ratio. Weight ratio strata affected overall survival, with quartile 1 (lower weight ratio recipients) experiencing the lowest 5-year survival (39.1%), followed by quartile 2 (57.8%), quartile 4 (68.2%), and quartile 3 (70.3%) recipients. The effect of weight ratio strata on survival was statistically significant for the quartile 1 recipients (lower quartile) as compared with the 3 other quartiles. Our findings show a statistically significant effect of donor-to-recipient weight ratios on bilateral lung transplantation survival. A higher donor-to-recipient weight ratio was associated with improved survival after bilateral lung transplantation and likely reflects a mismatch between a relatively overweight donor vs recipient. In contrast, a lower donor-to-recipient ratio was associated with increased mortality after bilateral lung transplantation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Different publications show an increased incidence of neoplasms in renal transplant patients. The objective of this study is to determine the incidence of cancer in the recipients of renal transplants performed in the A Coruña Hospital (Spain) during the period 1981–2007. During the study period 1967 kidney transplants were performed, corresponding to 1710 patients. Patients with neoplasms prior to the transplant will be excluded (n = 38). A follow-up study was carried out in order to estimate cancer incidence after transplantation. For each patient, information included donor and recipient characteristics, patients and graft survival and cancer incidence after transplantation. Incident cancer is considered as new cases of cancer after the transplant with anatomopathological confirmation. Their location will be classified according to the ICD-9. The analysis will be calculated using the indirect standardisation method. Age-adjusted cancer incidence rates in the Spanish general population will be obtained from the Carlos III Health Institute, the National Epidemiology Centre of the Ministry of Science and Technology. Crude first, second and third-year post-transplantation cancer incidence rates will be calculated for male and female recipients. The number of cases of cancer at each site will be calculated from data in the clinical records. The expected number of cancers will be calculated from data supplied by the Carlos III Health Institute. For each tumour location we will estimate the standardized incidence ratios (SIRs), using sex-specific cancer incidence rates, by dividing the incidence rate for the transplant patients by the rate of the general population. The 95% confidence intervals of the SIRs and their associated p-values will be calculated by assuming that the observed cancers follow a Poisson distribution. Stratified analysis will be performed to examine the variation in the SIRs with sex and length of follow-up. Competing risk survival analysis

    Awareness of factors affecting the place of death could improve communication between healthcare providers and patients and their families regarding patient preferences and the feasibility of dying in the preferred place.This study aimed to evaluate factors predicting home death among home palliative care recipients.This is a population-based study using a national representative sample retrieved from the National Health Insurance Research Database. Subjects receiving home palliative care, from 2010 to 2012, were analyzed to evaluate the association between a home death and various characteristics related to illness, individual, and health care utilization. A multiple-logistic regression model was used to assess the independent effect of various characteristics on the likelihood of a home death.The overall rate of a home death for home palliative care recipients was 43.6%. Age; gender; urbanization of the area where the patients lived; illness; the total number of home visits by all health care professionals; the number of home visits by nurses; utilization of nasogastric tube, endotracheal tube, or indwelling urinary catheter; the number of emergency department visits; and admission to intensive care unit in previous 1 year were not significantly associated with the risk of a home death. Physician home visits increased the likelihood of a home death. Compared with subjects without physician home visits (31.4%) those with 1 physician home visit (53.0%, adjusted odds ratio [AOR]: 3.23, 95% confidence interval [CI]: 1.93-5.42) and those with ≥2 physician home visits (43.9%, AOR: 2.23, 95% CI: 1.06-4.70) had higher likelihood of a home death. Compared with subjects with hospitalization 0 to 6 times in previous 1 year, those with hospitalization ≥7 times in previous 1 year (AOR: 0.57, 95% CI: 0.34-0.95) had lower likelihood of a home death.Among home palliative care recipients, physician home visits increased the likelihood of a home death.

    The use of the Internet for searching and sharing health information and for health care interactions may have a great potential for Renal Transplant Recipients (RTR). This study aims to determine the characteristics associated with Internet and social network use in a representative sample of RTR at the time of their inclusion in the study. Data of this cross-sectional design is retrieved from a longitudinal study conducted in five French kidney transplant centers in 2011, and included Renal Transplant Recipients aged 18 years with a functioning graft for at least 1 year. Measures include demographic characteristics (age, gender, level of education, employment status, living arrangement, having children, invalidity and monthly incomes in the household), psycho-social characteristics measured by the perceived social support questionnaire, and medical characteristics (previous dialysis treatment, duration since transplantation, graft rejection episodes, chronic graft dysfunction, health status and comorbidities: neoplasia for the current transplant, hypertension, diabetes mellitus, smoking status, BMI > 30 kg/m 2 and Charlson Comorbidity Index (CCI)). Polytomous linear regression analysis was performed to describe the Internet and social network users' profiles, using lack of Internet access as the comparison category. Among the 1416 RTR participating in the study, 20.1% had no Internet access in the household, 29.4% connected to social networks and 50.5% were not connected to social networks. Patients who connected the most to the Internet and social networks were younger, male, without children, employed, with high monthly incomes in the household, without hypertension and having felt a need for an informative or an esteem support. In our study, the majority of RTR were actively using Internet and social networks. Renal transplant units should develop flexible and Web-based sources related to transplant information, which will allow a rapid adaptation to

Few studies have described the performance of billing claims as surrogate measures of clinical events among kidney transplant recipients. Design, setting, participants, & measurements: We investigated the sensitivity of Medicare billing claims for clinically verified cardiovascular diagnoses (five categories) and procedures (four categories) in a novel database linking Medicare claims to electronic medical records of one transplant program. Cardiovascular events identified in medical records for 571 Medicare-insured transplant recipients in 1991 through 2002 served as reference measures. Results: Within a claims-ascertainment period spanning ±30 d of clinically recorded dates, aggregate sensitivity of single claims was higher for case definitions incorporating Medicare Parts A and B for diagnoses and procedures (90.9%) compared with either Part A (82.3%) or Part B (84.6%) alone. Perfect capture of the four procedures was possible within ±30 d or with short claims window expansion, but sensitivity for the diagnoses trended lower with all study algorithms (91.2% with window up to ±90 d). Requirement for additional confirmatory diagnosis claims did not appreciably reduce sensitivity. Sensitivity patterns were similar in the early compared with late periods of the study. Conclusions: Combined use of Medicare Parts A and B billing claims composes a sensitive measure of cardiovascular events after kidney transplant. Further research is needed to define algorithms that maximize specificity as well as sensitivity of claims from Medicare and other insurers as research measures in this population. PMID:19541817

    Prognostic data on survival of hepatitis B surface antigen-positive (HBsAg+) recipients and of hepatitis B core antibody-positive (HBcAb+) donors are limited in the thoracic transplantation (TT) cohort. Improved understanding of risks could potentially expand the recipient and donor pools. Post-hoc analysis of limited-access dataset of the United Network for Organ Sharing database from January 2000-September 2010 was performed. Analyses were performed for all TT, including single and bilateral lung, orthotopic heart, and simultaneous heart-lung transplants. The primary analyzed outcome was overall survival. A Cox proportional multivariate hazards model was used to adjust for significant risk predictors. Of 24,817 patients included, 426 recipients were HBsAg+, of whom 106 (25%) died during a mean follow-up of 3.6 years. On multivariate analysis, recipient HBsAg+ (hazard ratio [HR] = 0.88, 95% confidence interval [CI]: 0.69-1.32; P = 0.80), and donor HBcAb+ (HR = 0.91, 95% CI: 0.68-1.22; P = 0.53) were not associated with increased overall mortality in the entire TT cohort, with similar results for each individual transplant cohort. Unadjusted survival analysis using Kaplan-Meier curves in individual transplant cohorts did not show significant differences between HBsAg+ and HBsAg- recipients. No statistically significant differences were found between causes of mortality in the 2 groups. HBsAg+ status of recipients or HBcAb+ status of donors does not significantly affect overall survival of TT recipients. These data add to the scant literature on this subject and could potentially increase the donor and recipient pools. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Medical centers that work with transplants often face opportunisticinfections that demand specific tools to make diagnosis. Theprevalence of latent polyomavirus infections is high, and the mostcommon site of latency of the most prevalent polyomavirus in humans,BK virus (BKV, is the renal tissue. Hence, renal transplanted patientsare particularly vulnerable to the damage caused by viral reactivationduring immunosupression. In such patients BKV is associated toureteral stenosis and/or BKV nephropathy, leading to progressivedysfunction and graft loss, often diagnosed as rejection. In other organsrecipients (namely lung, liver, heart and pancreas, BKN is also the mostimportant clinical manifestation, whereas in bone marrow recipients themost common is hemorrhagic cystitis. This review presents the viralbiology and discusses the pathophysiology of polyomavirus diseasesand the diagnostic efficacy of the laboratory tests available, guidingto the best strategy for assessment and monitoring of patients at riskor under specific treatment.

    Pityriasis versicolor is a superficial infection of the stratum corneum, which is caused by the Malassezia species. Tge Malassezia species consist of 12 subspecies, including M. furfur, M. pachydermatis, M. symphodialis and M. globasa. The Malassezia species are classified as a normal flora, particularly in the sebum rich areas of the skin, and they convert from saprophytic yeast to parasitic mycelial morpholgic form to cause clinical disease. But majorities of their distributions are in the upper back, the neck, the thighs, and the forearm, and not in the penis. It is well known that the renal transplant patients, who take immunosuppressive agents, have impairment in the protective cell mediated immunity. Thus, they are more susceptible to infectious diseases, such as a fungal infection. Therefore, clinical manifestations show higher incidence of disease, but they mostly occur in an expected distribution. We here report a case of pityriasis versicolor in a renal transplant recipient on penile shaft, which is an unusual area.

    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    While sales flyer ad spending in Denmark has increased over the last decade ,the proportion of consumers declining to receive such flyers has been ever-increasing. To address this paradox, attitudinal and behavioural factors distinguishing passive recipients from active decliners of sales flyers...... are examined. The results reveal that decliners compared to receivers are less price conscious and that they perceive flyers as more inconvenient and less useful. Although decliners generally use other media less for deal searching than receivers, they are more inclined to search for grocery deals...... on the Internet.To reach the decliners, retailers could focus on the possibilities of the Internet, but to stop the trend of escalating numbers of decliners, retailers will have to address the perceived inconvenience and uselessness of sales flyers....

    This paper discusses studies in which thirty-seven renal transplant recipients, aged 20-79 years (mean age, 44 years), were prospectively studied with three-phase radionuclide bone scans and MR imaging because of possible osteonecrosis of the femoral heads. Both studies were performed within 2 weeks of transplant surgery. Ten hips (seven patients) had findings compatible with osteonecrosis on bone scans. Patients complained of pain in seven of these 10 hips. With MR imaging, 14 hips (nine patients) had findings compatible with osteonecrosis, and four hips (two patients) had early changes of osteonecrosis. MR findings were correlated clinically with pain in only seven hips (4 patients). Although MR imaging is a very sensitive technique for osteonecrosis, bone scan findings of osteonecrosis correlated better with pain

    Persuasive messages are more effective when they are custom-tailored to reflect the interests and concerns of the intended audience. Much of the message-framing literature has focused on the advantages of using either gain or loss frames, depending on the motivational orientation of the target group. In the current study, we extended this research to examine whether a persuasive appeal's effectiveness can be increased by aligning the message framing with the recipient's personality profile. For a single product, we constructed five advertisements, each designed to target one of the five major trait domains of human personality. In a sample of 324 survey respondents, advertisements were evaluated more positively the more they cohered with participants' dispositional motives. These results suggest that adapting persuasive messages to the personality traits of the target audience can be an effective way of increasing the messages' impact, and highlight the potential value of personality-based communication strategies.

    Full Text Available This investigation, aimed to study of intact parathormone (iPTH and calcium (Ca in a group of kidney transplanted patients and also we aimed to test the relationship of iPTH with various demographic data of kidney transplanted recipients. We studied 72 kidney transplanted persons with mean ages of 44±12 years. In this study, mean iPTH was 18.4±8.2 Pg/mL (median=16.5. A negative correlation of iPTH with creatinine clearance (r=-0.44, p0.05. In contrast to previous findings, in our patients, there was not secondary hyperparathyroidism. The results revealed suppressed PTH secretion. The reason may be due to excessive intake of calcium and Vitamin D analogues, which may suppress parathyroid hormone secretion.

    Studies have demonstrated the importance of patient perceptions' of mental health service quality. No studies, however, could be found that surveyed recipients in prison, despite the rapid growth of patients, and litigation in these settings. Patients were asked to complete an anonymous survey in private, and sealed it in an envelope. Of 613 respondents, most were satisfied (79%), agreed they had sufficient access to therapists (78%), were involved with treatment decisions (84%), and thought the MH services they had received would help them better deal with a crisis and emotional stress (75%). There were differences among mental health programs/housing units. Several of perception questions were significantly correlated with medication compliance, admission to crisis observation cells, and receiving disciplinary infractions. Random samples were requested, but likely only a convenience sample was obtained. However, the positive results suggest the need to strive to enhance patient quality of care ratings.

    Diltiazem is a benzothiazepine calcium blocker and widely used in renal transplant patients since it improves the level of tacrolimus or cyclosporine A concentration. Several population pharmacokinetic (PopPK) models had been established for cyclosporine A and tacrolimus but no specific PopPK model was established for diltiazem. The aim of the study is to develop a PopPK model for diltiazem in renal transplant recipients and provide relevant pharmacokinetic parameters of diltiazem for further pharmacokinetic interaction study. Patients received tacrolimus as primary immunosuppressant agent after renal transplant and started administration of diltiazem 90 mg twice daily on 5th day. The concentration of diltiazem at 0, 0.5, 1, 2, 8, and 12 h was measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Genotyping for CYP3A4*1G, CYP3A5*3, and MDR1 3435 was conducted by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). 25 covariates were considered in the stepwise covariate model (SCM) building procedure. One-compartment structural pharmacokinetic model with first-order absorption and elimination was used to describe the pharmacokinetic characteristics of diltiazem. Total bilirubin (TBIL) influenced apparent volume of distribution (V/F) of diltiazem in the forward selection. The absorption rate constant (K a ), V/F, and apparent oral clearance (CL/F) of the final population pharmacokinetic (PopPK) model of diltiazem were 1.96/h, 3550 L, and 92.4 L/h, respectively. A PopPK model of diltiazem is established in Chinese renal transplant recipients and it will provide relevant pharmacokinetic parameters of diltiazem for further pharmacokinetic interaction study.

    The aim of this study was to investigate (a) the extent to which age at first renal replacement therapy, achievement of developmental milestones, satisfaction of psychological needs, and coping were related to subjective well-being and medication adherence among young adult kidney transplant recipients; and (b) the relationship between subjective well-being and immunosuppressive medication adherence. A cross-sectional, interview study was conducted among renal transplant patients aged 20 to 30 years. In addition to sociodemographic and medical characteristics, concepts measured were: subjective well-being (Positive And Negative Affect Schedule; Satisfaction With Life Scale), medication adherence (Basel Assessment of Adherence to Immunosuppressive Medication Scale), dispositional coping (Brief COPE), achievement of developmental milestones (Course of Life Questionnaire), and satisfaction of psychological needs (Basic Psychological Needs Scale). Sixty-two patients participated (66% men; mean age, 26 years). Sixty-five percent were classified as nonadherent in the past month. In contrast, subjective self-rated overall adherence was high. None of the variables measured were related to nonadherence. Higher feelings of competence and autonomy, and timely achievement of social and psychosexual developmental milestones were related to higher subjective well-being. Well-being and adherence did not differ according to age at diagnosis or first renal replacement therapy. Two thirds of participants were classified as nonadherent which conflicts with participants' own high rating of medication adherence. This emphasizes the need for continued adherence support among young adult transplant recipients; however, no targets for interventions were found in this study. Potential targets for interventions aimed at improving well-being include competence and autonomy.

    Full Text Available Background: Kidney transplantation is the renal replacement therapy of choice for most patients with end-stage renal disease (ESRD, however, adherence to the recommended lifestyle is critical for a positive prognosis. The purpose of this study was to assess adherence to immunosuppressive therapy and lifestyle recommendations along with some related factors among kidney transplant patients. Materials and Methods: In this descriptive analytical study, all patients completed a questionnaire regarding medication intake and lifestyle recommendations (preventing of infection, self-monitoring, prevention of cardiovascular disease (CVD, and sun protection. The participants were divided into 4 groups according to the level of adherence (good, partial, poor, and nonadherent indicated in their responses. Results: Most kidney recipients were adherent to their drug prescriptions, but were partial, poor, or nonadherent regarding lifestyle recommendations. Increased passage of time since transplantation and low family support and educational level resulted in nonadherence. Men showed greater adherence to medication intake than women. Patients with lower number of drugs and reported drug side-effects illustrated better adherence to medication intake. Women adhered to infection protection recommendations more than men, and older and married patients adhered to cardiovascular prevention recommendations more than others. However, younger patients showed greater adherence to self-monitoring recommendations, and singles, young individuals, and women were adherent to sun protection recommendations. Conclusions: Nonadherence is common among kidney transplant recipients. Thus, it is necessary to determine patients who are at risk of nonadherence and to introduce more educational programs to improve their adherence and their quality of life (QOL.

    Objectives: To compare new onset dyslipidaemia in live-related renal transplant recipients taking cyclosporine versus tacrolimus after 3 months of therapy. Methods: The randomised controlled trial was conducted at the Sindh Institute of Urology and Transplantation (SIUT) Karachi, from September 2010 to April 2011, and included 182 End Stage Renal Disease patients on maintenance haemodialysis with pre-transplant normal lipid profile. The patients, who had live-related renal transplant, were randomly allocated to two equal groups using lottery. Group A received cyclosporine (3mg/kg) and group B was treated with tacrolimus (0.1mg/kg). All patients had pre-transplant fasting lipid profile checked when they were on maintenance haemodialysis and 3 months after renal transplantation. Serum fasting lipid profile was collected by taking 5ml blood by venipuncture after an overnight fast of 9-12 hours. SPSS 10 was used for statistical analyses. Results: Of the 182 patients, 144(79.1%) were males and 38(20.9%) were females. The overall mean age was 30.18+-9.57 years, and the mean weight was 54.41+- 11.144kg. Significant difference was not observed between the two groups regarding age and weight of the patients. Dyslipidaemia was found in 115(63.2%) subjects; 61(67%) in group A and 54(59.3%) in group B. There was no statistical difference (p=0.28) when comparison was done after 3 months of therapy. Conclusions: The occurrence of new onset hyperlipidaemia is similar in renal transplant recipients receiving either cyclosporine or tacrolimus in first 3 months post-transplant, but there is room for more research in this field as dyslipidaemia following successful renal transplantation is a frequent and persistent complication.

    Allograft rejection and long-term immunosuppression remain significant challenges in pediatric heart transplantation. Pediatric recipients are known to have fewer rejection episodes and to develop more allergic conditions than adults. A T-helper 2 cell dominant phenotype, manifested clinically by allergies and an elevated eosinophil count, may be associated with immunologic quiescence in transplant recipients. This study assessed whether the longitudinal eosinophil count and an allergic phenotype were associated with freedom from rejection. This single-center, longitudinal, observational study included 86 heart transplant patients monitored from 1994 to 2011. Post-transplant biannual complete blood counts, allergic conditions, and clinical characteristics related to rejection risk were examined. At least 1 episode of acute cellular rejection (ACR) occurred in 38 patients (44%), antibody-mediated rejection (AMR) occurred in 11 (13%), and 49 patients (57%) were diagnosed with an allergic condition. Patients with ACR or AMR had a lower eosinophil count compared with non-rejectors (p = 0.011 and p = 0.022, respectively). In the multivariable regression analysis, the presence of panel reactive antibodies to human leukocyte antigen I (p = 0.014) and the median eosinophil count (p = 0.011) were the only independent covariates associated with AMR. Eosinophil count (p = 0.010) and female sex (p = 0.009) were independent risk factors for ACR. Allergic conditions or young age at transplant were not protective from rejection. This study demonstrates a novel association between a high eosinophil count and freedom from rejection. Identifying a biomarker for low rejection risk may allow a reduction in immunosuppression. Further investigation into the role of the T-helper 2 cell phenotype and eosinophils in rejection quiescence is warranted. Copyright © 2015 International Society for Heart and Lung Transplantation.

Direct functional consequences of microparticle composition, especially internal composition, on recipient cells are poorly understood. Our objective was to evaluate if microparticle composition could impact the function of recipient cells, particularly during inflammatory provocation. We therefore engineered the composition of megakaryocyte culture-derived microparticles to generate distinct microparticle populations that were given to human monocytes to assay for influences recipient cell function. Herein, we tested the responses of monocytes exposed to either control microparticles or microparticles that contain the anti-inflammatory transcription factor, peroxisome proliferator-activated receptor-γ (PPARγ. In order to normalize relative microparticle abundance from two microparticle populations, we implemented a novel approach that utilizes a Nanodrop Spectrophotometer to assay for microparticle density rather than concentration. We found that when given to peripheral blood mononuclear cells, microparticles were preferentially internalized by CD11b+ cells, and furthermore, microparticle composition had a profound functional impact on recipient monocytes. Specifically, microparticles containing PPARγ reduced activated monocyte production of the proinflammatory cytokines interleukin-8 and monocyte chemotactic protein-1 compared to activated monocytes exposed to control microparticles. Additionally, treatment with PPARγ microparticles greatly increased monocyte cell adherence. This change in morphology occurred simultaneously with increased production of the key extracellular matrix protein, fibronectin and increased expression of the fibronectin-binding integrin, ITGA5.

    To investigate changes in glucose tolerance, insulin secretion and insulin sensitivity in Japanese recipients before and 1 year after renal transplantation. We conducted a study of Japanese recipients without diabetes who underwent renal transplantation at Hokkaido University Hospital. A 75-g oral glucose tolerance test was performed before and 1 year after renal transplantation in these recipients. Insulin sensitivity was estimated using the Matsuda index and homeostasis model assessment of insulin resistance (HOMA-IR). Insulin secretion was evaluated based on the insulin secretion sensitivity index-2 (ISSI-2). Of the 62 renal transplant recipients, 31 were diagnosed as having impaired glucose tolerance before transplantation. Among these 31 recipients, after 1 year, four had developed new-onset diabetes after transplantation, and nine had impaired glucose tolerance. Unexpectedly, 18 changed from impaired to normal glucose tolerance. When these recipients with impaired glucose tolerance were classified into a non-amelioration group and an amelioration group, the ISSI-2 was significantly reduced, with no significant changes in the Matsuda index or HOMA-IR, in the non-amelioration group 1 year after renal transplantation. By contrast, ISSI-2 and Matsuda index values were significantly increased, with no significant changes in HOMA-IR values in the amelioration group. More than half of Japanese renal transplant recipients with impaired glucose tolerance had normal glucose tolerance 1 year after renal transplantation. These results suggest that an increase in insulin secretion and whole insulin sensitivity was associated with improvement in glucose tolerance in these recipients. © 2016 Diabetes UK.

    A colistin-resistant mutant of Klebsiella pneumoniae served well as a donor but not as a recipient in conjugation. A nearly 1,000-fold difference between colistin-susceptible and colistin-resistant forms of this strain was observed by using donors of plasmids of four incompatibility groups. Recipient efficiency was not restored by filter matings.

    Children who receive a non-renal solid organ transplant may develop secondary renal failure requiring kidney transplantation. We investigated outcomes of 165 pediatric kidney transplant recipients who previously received a heart, lung, or liver transplant using data from 1988 to 2012 reported to the United Network for Organ Sharing. Patient and allograft survival were compared with 330 matched primary kidney transplant (PKT) recipients. Kidney transplantation after solid organ transplant (KASOT) recipients experienced similar allograft survival: 5- and 10-year graft survival was 78% and 60% in KASOT recipients, compared to 80% and 61% in PKT recipients (p = 0.69). However, KASOT recipients demonstrated worse 10-year patient survival (75% KASOT vs. 97% PKT, p transplants performed from 2006 to 2012 were separately investigated. Since 2006, KASOT and PKT recipients had similar 5-year graft survival (82% KASOT vs. 83% PKT, p = 0.48), although 5-year patient survival of KASOT recipients remained inferior (90% KASOT vs. 98% PKT, p Transplantation and the American Society of Transplant Surgeons.

    Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396), comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04). Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

    One of the most opportunistic infection in kidney transplant recipients is Cytomegalovirus. This study was conducted to find the frequency of cytomegalo- virus IgM and IgG in kidney transplant donors and recipients. Methods: We carried out retrospective analysis of laboratory values of cytomegalovirus IgG and IgM antibodies of all donors and recipients presented from 2006 to 2013 to National Institute of Kidney diseases Sheikh Zayed Hospital Lahore Pakistan. Results: Total no. of patients were 410 (205 donors and 205 recipients). Among recipients 169 (82%) were male and 36 (18%) female while among donors 125 (60%) were male and 80(40%) female. Total 05 (2.4 %) recipients were CMV IgG negative and 03 (1.4%) CMV IgM positive. Out of two hundred five recipients 200 (98%) were IgG positive and 202 (99%) were IgM negative. All the donors were CMV IgM negative and CMV IgG positive. Conclusion: There is very high frequency of CMV IgM and IgG positivity in donors and recipient of renal transplant in our population so we should consider prophylactic therapy. (author)

    Intramyocardial transplantation of cardiomyocytes (CMs), endothelial cells (ECs), and smooth muscle cells (SMCs) derived from human induced pluripotent stem cells (hiPSCs) has beneficial effects on the post-infarction heart. However, the mechanisms underlying the functional improvements remain undefined. We employed large-scale label-free quantitative proteomics to identify proteins that were differentially regulated following cellular transplantation in a swine model of myocardial infarction (MI). We identified 22 proteins that were significantly up-regulated after trilineage cell transplantation compared to both MI and Sham groups. Among them, 12 proteins, including adenylyl cyclase-associated protein 1 and tropomodulin-1, are associated with positive regulation of muscular contraction whereas 11 proteins, such as desmoplakin and zyxin, are involved in embryonic and muscular development and regeneration. Moreover, we identified 21 proteins up-regulated and another 21 down-regulated in MI, but reversed after trilineage cell transplantation. Proteins up-regulated after MI but reversed by transplantation are related to fibrosis and apoptosis. Conversely, proteins down-regulated in MI but restored after cell therapy are regulators of protein nitrosylation. Our results show that the functionally beneficial effects of trilineage cell therapy are accompanied by differential regulation of protein expression in the recipient myocardium, which may contribute to the improved cardiac function.

    Female renal transplant recipients of childbearing age may ask what the outcomes are for pregnancy and whether pregnancy will affect graft function. We analyzed obstetric and transplant outcomes among renal transplant recipients in our center who have been pregnant between 1973 and 2013. A case-cohort study was performed identifying 83 pairs of pregnant and non-pregnant controls matched for sex, age, transplant vintage, and creatinine. There were 138 pregnancies reported from 89 renal transplant recipients. There were live births in 74% of pregnancies with high prevalence of prematurity (61%), low birth weight (52%), and pre-eclampsia (14%). Lower eGFR (OR 0.98; p = 0.05) and higher uPCR (OR 1.86; p = 0.02) at conception were independent predictors for poor composite obstetric outcome. Lower eGFR (OR 0.98; p = 0.04), higher uPCR (OR 1.50; p = 0.04), and live organ donation (OR 0.35; p = 0.02) were predictors of ≥20% loss of eGFR between immediately pre-pregnancy and one yr after delivery. There was no difference in eGFR at one, five, and 10 yr in pregnant women compared with non-pregnant controls and a pregnancy was not associated with poorer 10-yr transplant or 20-yr patient survival. Despite high rates of obstetric complications, most women had successful pregnancies with good long-term transplant function. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Although many Western studies examining the mental health of welfare recipients exist, Japanese welfare recipients have been overlooked. This study investigated mental health among welfare recipients in Japan and relations with a sense of deprivation of life's necessities and social support. Participants (n = 305) completed the General Health Questionnaire-12 (GHQ-12), Proportional Deprivation Index, and a social support scale. Participants' GHQ-12 scores exceeded those of the general public, as 54.9% scored above the cut-off, suggesting poorer mental health among welfare recipients than the general population. Proportional Deprivation Index and emotional support from relatives and friends were associated with GHQ-12 scores. These results suggest that while chronic deprivation is associated with poorer mental health among welfare recipients, receiving emotional support may help cope with distress and maintain mental health. © The Author(s) 2016.

    Recipients of hematopoietic cell transplantation (HCT) are at risk for potentially preventable infectious complications because of defects in humoral and cell-mediated immunity. Studies of vaccine immunogenicity in HCT recipients have shown that antibody response rates depend on age, type of vaccine, and presence or absence of graft-versus-host disease. However, few large-scale studies have assessed the immune response to vaccination in HCT recipients. Additionally, HCT recipients have much higher rates of potentially preventable infections compared with the general population even after vaccination. This review evaluates the available studies and our view on the measurement of specific antibody titers, definition of an immune response, and durability of response in HCT recipients in both inactivated and live attenuated vaccines.

    Background The number of welfare recipients has steadily increased in Japan during recent years, although the number of homeless persons has decreased. Despite there being many reports regarding medicolegal death among homeless persons, medicolegal death among welfare recipients has not been fully investigated. Methods We identified 10,293 individuals who received welfare aid during their lifetime among the 81,867 cases that were examined by the Tokyo Medical Examiner's Office (2008-2013). We retrospectively compared the proportions of medicolegal death to total population, age, sex, family status, clinical history, and manners/causes of death among non-indigent persons (controls), homeless persons, and welfare recipients. Results A higher proportion of medicolegal death to total population was observed among the welfare recipients, compared with the controls. The welfare recipients (65.5 years) were younger than the controls (68.9 years), and the proportions of male sex and living alone were higher among the welfare recipients. Hypertension and circulatory disease were the leading clinical conditions among the welfare recipients. Death due to disease was the leading manner of death, and circulatory disease was the leading cause of death among the welfare recipients. The proportion of individuals with a long period between death and discovery (which made determining the cause of death difficult) was also higher among the welfare recipients. Conclusion Welfare recipients have a greater risk of sudden death compared with non-indigent persons. Preventive strategies should target middle-aged to elderly men who live alone, and should address their risks of circulatory diseases and solitary death.

    Primary central nervous system lymphoma (PCNSL) risk is greatly increased in immunosuppressed human immunodeficiency virus-infected people. Using data from the US transplant registry linked with 17 cancer registries (1987-2014), we studied PCNSL and systemic non-Hodgkin lymphoma (NHL) in 288 029 solid organ transplant recipients. Transplant recipients had elevated incidence for PCNSL compared with the general population (standardized incidence ratio = 65.1; N = 168), and this elevation was stronger than for systemic NHL (standardized incidence ratio=11.5; N = 2043). Compared to kidney recipients, PCNSL incidence was lower in liver recipients (adjusted incidence rate ratio [aIRR] = 0.52), similar in heart and/or lung recipients, and higher in other/multiple organ recipients (aIRR = 2.45). PCNSL incidence was higher in Asians/Pacific Islanders than non-Hispanic whites (aIRR = 2.09); after induction immunosuppression with alemtuzumab (aIRR = 3.12), monoclonal antibodies (aIRR = 1.83), or polyclonal antibodies (aIRR = 2.03); in recipients who were Epstein-Barr virus-seronegative at the time of transplant and at risk of primary infection (aIRR = 1.95); and within the first 1.5 years after transplant. Compared to other recipients, those with PCNSL had increased risk of death (adjusted hazard ratio [aHR] = 11.79) or graft failure/retransplantation (aHR = 3.24). Recipients with PCNSL also had higher mortality than those with systemic NHL (aHR = 1.48). In conclusion, PCNSL risk is highly elevated among transplant recipients, and it carries a poor prognosis. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Kaposi's Sarcoma (KS) is a tumour of multicentric origin with increased frequency after organ transplantation. To date, only North American data from the Cincinnati Transplant Tumor Registry have given some information about this disease in organ transplant recipients, but its true prevalence still has to be determined. In order to analyze Kaposi's sarcoma after kidney, liver and heart transplantation, we performed a retrospective study using the oldest registry of organ transplant recipients in Europe. Among all 7923 organ transplant recipients recorded in the Groupe Collaboratif de Recherche en Transplantation de l'Ile de France (GCIF) registry from 1968 to 1990, we analyzed the prevalence and the clinical characteristics of Kaposi's sarcoma in 6229 kidney, 727 liver and 967 heart transplant recipients. In the subgroup of kidney transplant recipients, we assessed the role of cyclosporine on disease evolution. Overall prevalence of Kaposi's sarcoma after organ transplantation was 0.52%, but it was significantly higher among liver (1.24%) than among kidney (0.45%) and heart (0.41%) transplant recipients. Chronic hepatitis B surface antigen carriers were more frequent in liver than in kidney transplant recipients who developed Kaposi's sarcoma (66% vs 21%, p < 0.03). Following kidney transplantation, Kaposi's sarcoma was more severe in patients receiving cyclosporine (n = 16) when compared with those under conventional immunosuppression (n = 12). True prevalence of Kaposi's sarcoma among European transplant recipients is high (0.52%) and appeared significantly higher in liver compared with other organ transplant recipients. Cyclosporine seems to increase severity of the disease among kidney transplant recipient.

    Natural killer (NK) cells are reported to have an important role in the resistance of lethally irradiated recipients to bone marrow transplantation (BMT). Therefore, we investigated the effects of recipient NK depletion on survival, chimerism, and hematopoietic reconstitution after lethal irradiation and the transplantation of limiting amounts of T-cell-deficient bone marrow (BM). When administered before BMT, anti-asialo GM1 (ASGM1) antiserum treatment, effective in depleting in vivo NK activity, was associated with a marked increase in survival in 3 of 3 allogeneic combinations (BALB/c into C3H/HeN, C57B1/6, or C3B6F1). This enhanced survival was independent of the susceptibility of each recipient strain to accept BALB/c BM. Moreover, recipient anti-ASGM1 treatment was also effective in increasing survival in recipients of syngeneic BM, suggesting that NK cells can adversely affect engraftment independent of genetically controlled polymorphic cell surface determinants. Analysis of chimerism in surviving animals 2 months post-BMT showed that recipient NK depletion significantly increased the level of donor engraftment when high doses of BM were transplanted. These studies also demonstrated that anti-ASGM1 pretreatment mainly resulted in an increase in extramedullary hematopoiesis in the second and third week after irradiation. Anti-ASGM1 treatment also dramatically accelerated the rate of appearance of donor-derived cells with a higher level of donor-cell engraftment apparent at a time when the differences in survival between NK-depleted and control BMT recipients became significant. Peripheral cell counts were also affected by NK depletion, with significantly enhanced platelet and red blood cell recovery and a moderate increase in granulocyte recovery

    Retrospective analysis was done on 235 recipients, 133 males and 102 females, who were transplanted between 25th September 1979 and 25th June 1999. 85.1% were Chinese, 7.7% were Indians and 7.2% Malays. 23% (54) were living related renal transplants (LRRT) all except 5 done at Hospital Kuala Lumpur. 60% (141) were living unrelated donor renal transplants (LURT) done in India. 17% (40) were cadaveric transplants (CADT) (all done in China except 2 at Hospital Kuala Lumpur and one in London). 97% (228) were first transplants. Primary renal disease was unknown in 69.4%, 17% (40) glomerulonephritis, 5.5% diabetic nephropathy and 8.1% 19 others. All were on prednisolone, 93.2% were on azathioprine and 96.6% were on cyclosporin A. The acute rejection rate was 23.4% (55 episodes). Patient survival was 88% at five years and patients alive with functioning graft was 84% at 5 years. LRRT had significantly better survival compared to LURT. 34 grafts were lost to chronic allograft nephropathy. 46 recipients died (33 died with functioning graft).

    Full Text Available Abstract Background Adiponectin is a major adipocyte-derived protein with insulin-sensitizing, anti-inflammatory and anti-atherogenic properties. Adiponectin levels correlate inversely with renal function and higher levels are predictive of lower cardiovascular disease (CVD in patients with normal renal function and chronic kidney disease. No data exists on the association between adiponectin and CVD in renal transplant recipients (RTR. Methods Standard biochemistry, clinical data and adiponectin were collected from 137 RTR recruited to the LANDMARK 2 study at baseline. The LANDMARK 2 study is an ongoing randomized controlled study that compares the outcome of aggressive risk factor modification for cardiovascular disease versus standard post-transplant care in renal transplant recipients with impaired glucose tolerance or diabetes mellitus. Results Mean patient age was 53.4 ± 12 years and the median post-transplantation period was 5 (0.5-31.9 years. Mean serum adiponectin level was 12.3 ± 7.1 μg/mL. On univariate analysis, adiponectin was positively associated with female gender (P = 0.01 and serum high-density lipoprotein (HDL concentration (P Conclusion In conclusion, adiponectin is positively correlated with inflammation, dyslipidemia and abnormal glucose tolerance in RTR. Furthermore, hypoadiponectinemia correlated with increased baseline CVD in male RTR.

    To evaluate incidence, risk factors and treatment outcome of BK polyomavirus nephropathy (BKVN) in a cohort of renal transplant recipients in the Auckland region without a formal BK polyomavirus (BKV) surveillance programme. A cohort of 226 patients who received their renal transplants from 2006 to 2012 was retrospectively reviewed. Seventy-six recipients (33.6%) had a BK viral load (BKVL) test and 9 patients (3.9%) developed BKVN. Cold ischaemia time (HR = 1.18, 95%CI: 1.04-1.35) was found to be a risk factor for BKVN. Four recipients with BKVN had complete resolution of their BKV infection; 1 recipient had BKVL less than 625 copies/mL; 3 recipients had BKVL more than 1000 copies/mL and 1 had graft failure from BKVN. BKVN has a negative impact on graft function [median estimated glomerular filtration rate (eGFR) 22.5 (IQR 18.5-53.0) mL/min per 1.73 m 2 , P = 0.015), but no statistically significant difference ( P = 0.374) in renal allograft function was found among negative BK viraemia group [median eGFR 60.0 (IQR 48.5-74.2) mL/min per 1.73 m 2 ), positive BK viraemia without BKVN group [median eGFR 55.0 (IQR 47.0-76.0) mL/min per 1.73 m 2 ] and unknown BKV status group [median eGFR 54.0 (IQR 43.8-71.0) mL/min per 1.73 m 2 ]. The incidence and treatment outcomes of BKVN were similar to some centres with BKV surveillance programmes. Recipients with BVKN have poorer graft function. Although active surveillance for BKV has been shown to be effective in reducing incidence of BKVN, it should be tailored specifically to that transplant centre based on its epidemiology and outcomes of BKVN, particularly in centres with limited resources.

    Renal transplant recipients (RTR) have reduced peak aerobic capacity, muscle strength, arterial function and an unfavorable cardiovascular disease risk (CVD) profile. This study compared the effects of 12 weeks of supervised endurance and strength training (EST, n = 16) versus usual care (UC, n = 15) on peak aerobic capicity, cardiovascular and skeletal muscle function, CVD risk profile, and quality of life (QOL) in RTR (55 ± 13 years). Peak aerobic capacity and exercise hemodynamics, arterial compliance, 24-h blood pressure, muscle strength, lean body mass, CVD risk score, and QOL were assessed before and after 12 weeks. The change in peak aerobic capacity (EST: 2.6 ± 3.1 vs. UC: -0.5 ± 2.5 mL/(kg·min)), cardiac output (EST: 1.7 ± 2.6 vs. UC: -0.01 ± 0.8 L/min), leg press (EST: 48.7 ± 34.1 vs. UC: -10.5 ± 37.7 kg) and leg extension strength (EST: 9.5 ± 10.3 vs. UC: 0.65 ± 5.5 kg) improved significantly after EST compared with UC. The overall change in QOL improved significantly after 12 weeks of EST compared with UC. No significant difference was found between groups for lean body mass, arterial compliance, 24-h blood pressure or CVD risk score. Supervised EST is an effective intervention to improve peak exercise aerobic capacity and cardiac output, muscle strength and QOL in clinically stable RTR.

    We report a case of a 57-year-old woman with type I diabetes who had received a simultaneous pancreas-kidney (SPK) transplant maintained on tacrolimus, mycophenolic acid (MPA) and prednisolone. Her renal allograft failed 6 years post-transplant but she continued to have a normal functioning pancreatic allograft. Over the course of 5 years, she developed progressive bone marrow failure with repeat bone marrow aspirates demonstrating an evolution from erythroid hypoplasia to hypocellular marrow and eventual aplastic anaemia despite discontinuation of MPA and reduction of tacrolimus. She was transfusion-dependent and had frequent admissions for sepsis. Despite treatment with antithymocyte globulin and cyclosporine for aplastic anaemia, she developed fatal invasive pulmonary aspergillosis within 3 weeks of treatment. Even though the cause of aplastic anaemia is likely multifactorial, this case highlights the difficulty in balancing the need for versus the risk of ongoing immunosuppression in a SPK transplant recipient who continues to have normal pancreatic graft function. 2014 BMJ Publishing Group Ltd.

    Full Text Available Kidney allograft failure due to chronic injury/rejection remains the main cause of graft loss in renal transplant recipients (RTR. Here, we investigated whether specific biomarkers of extracellular matrix (ECM turnover are associated with allograft function and chronic kidney disease (CKD stage in RTR. Seventy-eight patients who attended the University Medical Center Groningen for a routine check-up after kidney transplantation were enrolled in the study. Plasma and/or 24h-urine samples were collected and specific matrix-metalloproteinase-generated neo-epitope fragments of collagens were measured by enzyme-linked immunosorbent assay. Our results demonstrated that urinary levels of C3M, a marker for collagen type III degradation, correlated with estimated glomerular filtration rate (eGFR; r = 0.58, p<0.0001, with lower levels detected in the urine of patients with advanced CKD. In addition, plasma levels of Pro-C6, a marker for collagen type VI formation, significantly increased with disease progression and correlated with eGFR (r = -0.72, p<0.0001. Conversely, plasma C3M and urinary Pro-C6 levels showed no correlation with renal function. We identified two neo-epitope biomarkers of tissue turnover associated with ECM remodeling and fibrosis that can stratify patients by CKD stage. This is as promising first step towards non-invasive monitoring of ECM turnover in the kidneys.

    We analyzed the levels of fitness, muscle structure and quality of life of adults after kidney transplant and healthy adults. A total of 16 kidney transplant patients and 21 healthy controls performed several fitness test, isokinetic evaluation of knee flexion and extension and ultrasonography muscle thickness assessment. They also completed the quality of life questionnaire SF-36. Physical fitness, muscle structure and quality of life of the kidney transplant recipients were significantly poorer than the controls. The transplant patients performed less well in the "get up and go" and "sit to stand" test (p<.001) as well as in assessments of muscle structure, strength and power. The patients had a poorer score in their quality of life assessments, differing from the controls in domains of physical function, physical role, general health and social function (p<.001). Fitness, strength and muscle mass are diminished in kidney transplant patients, resulting in a poorer quality of life which might entail an increased risk to their health.

    There is a high prevalence of metabolic syndrome in liver transplant recipients, a population that tends to be physically inactive. The aim of this study was to characterize physical activity and evaluate the relationship between physical activity and metabolic syndrome after liver transplantation. A cross-sectional analysis was performed in patients more than 3 months after transplantation. Metabolic syndrome was classified according to National Cholesterol Education Panel Adult Treatment Panel III guidelines. Physical activity, including duration, frequency, and metabolic equivalents of task (METs), was assessed. The study population consisted of 204 subjects, with 156 more than 1 year after transplantation. The median time after transplantation was 53.5 months (range = 3-299 months). The mean duration of exercise was 90 ± 142 minutes, and the mean MET score was 3.6 ± 1.5. Metabolic syndrome was observed in 58.8% of all subjects and in 63.5% of the subjects more than 1 year after transplantation. In a multivariate analysis involving all subjects, metabolic syndrome was associated with a time after transplantation greater than 1 year [odds ratio (OR) = 2.909, 95% confidence interval (CI) = 1.389-6.092] and older age (OR = 1.036, 95% CI = 1.001-1.072). A second analysis was performed for only patients more than 1 year after transplantation. In a multivariate analysis, metabolic syndrome was associated with lower exercise intensity (OR = 0.690, 95% CI = 0.536-0.887), older age (OR = 1.056, 95% CI = 1.014-1.101), and pretransplant diabetes (OR = 4.246, 95% CI = 1.300-13.864). In conclusion, metabolic syndrome is common after liver transplantation, and the rate is significantly higher in patients more than 1 year after transplantation. The observation that exercise intensity is inversely related to metabolic syndrome after transplantation is novel and suggests that physical activity might provide a means for reducing metabolic syndrome complications in liver

  16. Oral Valganciclovir as a Preemptive Treatment for Cytomegalovirus (CMV Infection in CMV-Seropositive Liver Transplant Recipients.

    Full Text Available Cytomegalovirus (CMV infections in liver transplant recipients are common and result in significant morbidity and mortality. Intravenous ganciclovir or oral valganciclovir are the standard treatment for CMV infection. The present study investigates the efficacy of oral valganciclovir in CMV infection as a preemptive treatment after liver transplantation.Between 2012 and 2013, 161 patients underwent liver transplantation at Samsung Medical Center. All patients received tacrolimus, steroids, and mycophenolate mofetil. Patients with CMV infection were administered oral valganciclovir (VGCV 900mg/day daily or intravenous ganciclovir (GCV 5mg/kg twice daily as preemptive treatment. Stable liver transplant recipients received VGCV.Eighty-three patients (51.6% received antiviral therapy as a preemptive treatment because of CMV infection. The model for end-stage liver disease (MELD score and the proportions of Child-Pugh class C, hepatorenal syndrome, and deceased donor liver transplantation in the CMV infection group were higher than in the no CMV infection group. Sixty-one patients received GCV and 22 patients received VGCV. The MELD scores in the GCV group were higher than in the VGCV group, but there were no statistical differences in the pretransplant variables between the two groups. AST, ALT, and total bilirubin levels in the GCV group were higher than in the VGCV group when CMV infection occurred. The incidences of recurrent CMV infection in the GCV and VGCV groups were 14.8% and 4.5%, respectively (P=0.277.Oral valganciclovir is feasible as a preemptive treatment for CMV infection in liver transplant recipients with stable graft function.

  17. Association of the multidrug resistance-1 gene single-nucleotide polymorphisms with the tacrolimus dose requirements in renal transplant recipients.

    The immunosuppressive drug tacrolimus, whose pharmacokinetic characteristics display large interindividual variations, is a substrate for P-glycoprotein (P-gp), the product of the multidrug resistance-1 (MDR1) gene. Some of the single nucleotide polymorphisms (SNP) of MDR1 reported correlated with the in vivo activity of P-gp. Because P-gp is known to control tacrolimus intestinal absorption, it was postulated that these polymorphisms are associated with tacrolimus pharmacokinetic variations in renal transplant recipients. The objective of this study was to evaluate in a retrospective study of 81 renal transplant recipients the effect on tacrolimus dosages and concentration/dose ratio of four frequent MDR1 SNP possibly associated with P-gp function (T-129C in exon 1b, 1236C>T in exon 12, 2677G>T,A in exon 21, and 3435C>T in exon 26). As in the general population, the SNP in exons 12, 21, and 26 were frequent (16, 17.3, and 22.2% for the variant homozygous genotype, respectively) and exhibited incomplete linkage disequilibrium. One month after tacrolimus introduction, exon 21 SNP correlated significantly with the daily tacrolimus dose (P < or = 0.05) and the concentration/dose ratio (P < or = 0.02). Tacrolimus dose requirements were 40% higher in homozygous than wild-type patients for this SNP. The concentration/dose ratio was 36% lower in the wild-type patients, suggesting that, for a given dose, their tacrolimus blood concentration is lower. Haplotype analysis substantiated these results and suggested that exons 26 and 21 SNP may be associated with tacrolimus dose requirements. Genotype monitoring of the MDR1 gene reliably predicts the optimal dose of tacrolimus in renal transplant recipients and may predict the initial daily dose needed by individual patients to obtain adequate immunosuppression.

    Hyperparathyroidism is present in up to 50% of transplant recipients 1 year after transplant, often despite good graft function. Posttransplant patients frequently have hypercalcemia-associated hyperparathyroidism, limiting the role of vitamin D analogues and sometimes requiring parathyroidectomy. Multiple observational studies have investigated treatment of posttransplant hyperparathyroidism with the calcimimetic agent cinacalcet. We performed a systematic review and meta-analysis of prospective and retrospective studies from 2004 through January 26, 2012, using MEDLINE. We identified studies evaluating treatment with cinacalcet in renal transplant recipients with hyperparathyroidism. We performed random effects meta-analysis to determine changes in calcium, phosphorus, parathyroid hormone, and serum creatinine. Twenty-one studies with 411 kidney transplant recipients treated with cinacalcet for hyperparathyroidism met inclusion criteria. Patients were treated for 3 to 24 months. By meta-analysis, calcium decreased by 1.14 mg/dL (95% confidence interval, -1.00 to -1.28), phosphorus increased by 0.46 mg/dL (95% confidence interval, 0.28-0.64), parathyroid hormone decreased by 102 pg/mL (95% confidence interval, -69 to -134), and there was no significant change in creatinine (0.02 mg/dL decrease; 95% confidence interval, -0.09 to 0.06). Cinacalcet resulted in hypocalcemia in seven patients. The most common side effect was gastrointestinal intolerance. From nonrandomized studies, cinacalcet appears to be safe and effective for the treatment of posttransplant hyperparathyroidism. Larger observational studies and randomized controlled trials, performed over longer follow-up times and looking at clinical outcomes, are needed to corroborate these findings.

  19. Augmentation of transfer of experimental autoimmune thyroiditis (EAT) in mice by irradiation of recipients

    Experimental autoimmune thyroiditis (EAT) can be adoptively transferred to normal syngeneic recipients using spleen cells from susceptible strains of mice primed in vivo with mouse thyroglobulin (MTg) and lipopolysaccharide (LPS) following in vitro activation of spleen cells by culture with MTg. Irradiation of recipient animals markedly augments the severity of thyroiditis induced in this system. Irradiation of recipients does not alter the time course of the development of thyroiditis, nor does it alter the requirement for both in vivo priming and in vitro activation of spleen cells for the development of EAT. Spleen cells from EAT-resistant strains of mice (e.g., Balb/c) do not induce EAT in irradiated recipients. Irradiated recipients develop significant levels of anti-MTg antibodies while unirradiated recipients have little detectable antibody response. The augmenting effect of irradiation can be substantially reversed by transferring naive spleen cells to recipients prior to the transfer of MTg/LPS-primed in vitro-activated spleen cells. In addition athymic CBA/Tufts nude mice develop more severe EAT than CBA/Tufts nude/+ littermates following transfer of activated CBA/J spleen cells. These data suggest that natural suppressor cells may regulate the development of EAT at the effector cell level

    Adult cochlear implant (CI) recipients demonstrate a reliable relationship between spectral modulation detection and speech understanding. Prior studies documenting this relationship have focused on postlingually deafened adult CI recipients-leaving an open question regarding the relationship between spectral resolution and speech understanding for adults and children with prelingual onset of deafness. Here, we report CI performance on the measures of speech recognition and spectral modulation detection for 578 CI recipients including 477 postlingual adults, 65 prelingual adults, and 36 prelingual pediatric CI users. The results demonstrated a significant correlation between spectral modulation detection and various measures of speech understanding for 542 adult CI recipients. For 36 pediatric CI recipients, however, there was no significant correlation between spectral modulation detection and speech understanding in quiet or in noise nor was spectral modulation detection significantly correlated with listener age or age at implantation. These findings suggest that pediatric CI recipients might not depend upon spectral resolution for speech understanding in the same manner as adult CI recipients. It is possible that pediatric CI users are making use of different cues, such as those contained within the temporal envelope, to achieve high levels of speech understanding. Further investigation is warranted to investigate the relationship between spectral and temporal resolution and speech recognition to describe the underlying mechanisms driving peripheral auditory processing in pediatric CI users.

    Reduction of cardiovascular death might have a significant effect on the long-term survival rates of renal transplant recipients (RTRs). The aim of the study was to assess the relation between arterial stiffness and graft function, adipose tissue content, and hydration status in patients after kidney transplantation (KTx).The study included 83 RTR patients (mean age: 55 ± 13 years) who had been admitted to a nephrology-transplantation outpatient clinic 0.5 to 24 years after KTx. Clinical and laboratory data were analyzed and eGFR was calculated with the CKD-EPI formula. Arterial stiffness was assessed in all RTRs with pulse wave propagation velocity (PWV) with the use of a complior device. In addition, fluid and nutritional status was assessed with a Tanita BC 418 body composition analyzer. The control group consisted of 31 hospital workers who received no medication and had no history of cardiovascular disease.Multivariable linear regression analysis, with PWV as a dependent variable, retained the following independent predictors in the final regression model: red blood cell distribution width (RDW) (B = 0.323; P = 0.004), age (B = 0.297; P = 0.005), tacrolimus therapy (B = -0.286; P = 0.004), and central DBP (B = 0.185; P = 0.041). Multivariable linear regression analysis with eGFR as a dependent variable retained the following independent predictors in the final regression model; creatinine concentration (B = -0.632; P = 0.000), hemoglobin (B = 0.280; P = 0.000), CRP (B = -0.172; P = 0.011), tacrolimus therapy (B = 0.142; P = 0.039), and triglycerides (B = -0.142; P = 0.035).Our data indicates that: kidney transplant recipients can present modifiable CVD risk factors linked to increased arterial stiffness, DBP, waist circumference, SCr, time on dialysis, CyA therapy, and visceral fat mass; RDW is a parameter associated with arterial stiffness; and parameters such as CyA therapy, time on

  2. Kidney Transplantation and HIV: Does Recipient Privacy Outweigh the Donor's Right to Information?

    2010-01-01

    Background and objectives: There exists an inherent conflict between a kidney donor's right to know key aspects of a recipient's medical history and specific disease, such as HIV, where federal and state statues protect this information. The authors of the live organ donor consensus group expressly stated the principal of a donor's right to recipient information. This information includes the risks and benefits of not only the donation procedure, but also the risks, benefits, and alternative treatment options of the recipient. In this paper, a case will be presented highlighting this conflict and the ethical and legal reasoning used to resolve it. Design, setting, participants, & measurements: A 22-year-old woman came forward as a directed kidney donor for an HIV-positive individual. The donor and recipient were medically appropriate for kidney donation and transplantation. During the donor advocacy panel review, there was disagreement regarding whether or not the potential donor had the right to know about the HIV status of the potential recipient. Results: In living kidney transplantation to HIV-positive individuals, the recipient's right to privacy of information outweighs the donor's right to know. Conclusions: Although protecting the recipient's right to privacy is paramount, the donor is still entitled to consider factors a priori that could alter their decision to donate. This can be accomplished by informing the donor that they are not entitled to protected health information of the recipient and that their decision to donate should be based on knowing the recipient is medically appropriate for kidney transplantation.

    Age and body mass index (BMI) of kidney donors and recipients affect kidney allograft outcomes. Moreover, while deceased donor and recipient body size mismatch have been reported to influence allograft outcomes, how BMI mismatch in living kidney donor-recipient pairs affect graft survival is not well defined. We investigated trends in characteristics of 90,815 US. living kidney donors and their recipients between 1987 and 2008. Median ages of donors and their recipients have risen over time, and the proportion of living donors age ≥ 50 years increased from 11 to 25%. Median BMI of recipients increased from 22.6 to 26.6 kg/m(2); median BMI of kidney donors for the past 5 years has been 26.4 kg/m(2). Only 35% of living donor-recipient pairs were in the same BMI category (<25, 25-29.9, 30-34.9, or ≥ 35 kg/m(2)). BMI mismatch where the living donor was three categories heavier than the recipient was associated with a significant adjusted risk for death-censored allograft loss (HR 2.31, 95% CI 1.05-5.08). Living kidney donors are donating at more advanced ages, and the majority are overweight or obese in recent years. In summary: (1) previous longitudinal studies of living kidney donor outcomes may not be generalizable to recent donors, and studies of contemporary living kidney donor cohorts may be informative, (2) the majority of living donor-recipient pairs have BMI mismatch, and (3) extreme BMI mismatch where the living donor is heavier may confer an independent risk for allograft loss.

    Little is known about associations of family health history with outcomes after kidney donation. Using a database wherein Organ Procurement and Transplantation Network identifiers for 4650 living kidney donors in 1987 to 2007 were linked to administrative data of a US private health insurer (2000-2007 claims), we examined associations of recipient illness history as a measure of family history with postdonation diagnoses and drug-treatment for hypertension and diabetes. Cox regression with left and right censoring was applied to estimate associations (adjusted hazards ratios, aHR) of recipient illness history with postnephrectomy donor diagnoses, stratified by donor-recipient relationship. Recipient end-stage renal disease from hypertension, as compared with other recipient end-stage renal disease causes, was associated with modest, significant increases in the age- and gender-adjusted relative risks of hypertension diagnosis (aHR, 1.37%; 95% confidence interval [CI], 1.08-1.74) after donor nephrectomy among related donors. After adjustment for age, gender, and race, recipient type 2 diabetes compared with non-diabetic recipient status was associated with twice the relative risk of postdonation diabetes (aHR, 2.14; 95% CI, 1.28-3.55; P=0.003) among related donors. These patterns were significant among white but not among non-white related donors. Recipient type 1 diabetes was associated with postdonation diabetes only in black related donors (aHR, 3.22; 95% CI, 1.04-9.98; P=0.04). Recipient illness did not correlate significantly with outcomes in unrelated donors. These data support a need for further study of family health history as a potential sociodemographic correlate of donor outcomes, including examination of potential mediating factors and variation in risk discrimination among donors of different racial groups.

    Airway complications (ACs) after living-donor lobar lung transplantation (LDLLT) could have different features from those after cadaveric lung transplantation (CLT). We conducted this study to compare the characteristics of ACs after LDLLT vs. those after CLT and investigate their impact on outcomes. We reviewed, retrospectively, data on 163 recipients of lung transplantation, including 83 recipients of LDLLT and 80 recipients of CLT. The incidence of ACs did not differ between LDLLT and CLT. The initial type of AC after LDLLT was limited to stenosis in all eight patients, whereas that after CLT consisted of stenosis in three patients and necrosis in ten patients (p = 0.0034). ACs after LDLLT necessitated significantly earlier initiation of treatment than those after CLT (p = 0.032). The overall survival rate of LDLLT recipients with an AC was significantly lower than that of those without an AC (p = 0.030), whereas the overall survival rate was comparable between CLT recipients with and those without ACs (p = 0.25). ACs after LDLLT, limited to bronchial stenosis, require significantly earlier treatment and have a greater adverse impact on survival than ACs after CLT.

    The Red Nacional de Donación y Trasplantes of the Colombian Instituto Nacional de Salud reported that in 2014, 1,059 organ transplants were performed, of which 761 were kidney transplants, and 643 (84.5%) of these were from cadaveric organ donors. To describe the socio-demographic characteristics of patients who received renal transplants, as well as their outcomes in terms of survival. National kidney transplants were analyzed through an observational retrospective cohort study. Overall survival was estimated using the Kaplan-Meier method. The survival curves by sex, age, type of donor, type of insurance, and time on the waiting list were compared utilizing the log rank hypothesis and a Cox regression. A total of 3,980 patients were included, of whom 338 died according to the Registry of Affiliates. The median follow-up time was 49 months, overall survival was 6.35 years (95% CI: 6.30 to 6.40), the one-year survival following transplantation was 97.2%, the three-year survival, 93.2%, and the five-year survival, 90.8%. The survival rate was higher in patients under 50 years of age, receptors of living donor transplants, and with less than six months on the waiting list. The results obtained serve as the basis for future studies with strict monitoring of survival among kidney transplant recipients in Colombia.

    The critical role of the mammalian hippocampus in the formation, translation and retrieval of memory has been documented over many decades. There are many theories of how the hippocampus operates to encode events and a precise mechanism was recently identified in rats performing a short-term memory task which demonstrated that successful information encoding was promoted via specific patterns of activity generated within ensembles of hippocampal neurons. In the study presented here, these “representations” were extracted via a customized non-linear multi-input multi-output (MIMO) mathematical model which allowed prediction of successful performance on specific trials within the testing session. A unique feature of this characterization was demonstrated when successful information encoding patterns were derived online from well-trained “donor” animals during difficult long-delay trials and delivered via online electrical stimulation to synchronously tested naïve “recipient” animals never before exposed to the delay feature of the task. By transferring such model-derived trained (donor) animal hippocampal firing patterns via stimulation to coupled naïve recipient animals, their task performance was facilitated in a direct “donor-recipient” manner. This provides the basis for utilizing extracted appropriate neural information from one brain to induce, recover, or enhance memory related processing in the brain of another subject. PMID:24421759

    Critical limb ischemia (CLI) with distal leg necrosis in lung transplant recipients (LTR) is associated with a high risk for systemic infection and sepsis. Optimal management of CLI has not been defined so far in LTR. In immunocompetent individuals with leg necrosis, surgical amputation would be indicated and standard care. We report on the outcome of four conservatively managed LTR with distal leg necrosis due to peripheral arterial disease (PAD) with medial calcification of the distal limb vessels. Time interval from lung transplantation to CLI ranged from four years (n = 1) to more than a decade (n = 3). In all cases a multimodal therapy with heparin, acetylsalicylic acid, iloprost and antibiotic therapy was performed, in addition to a trial of catheter-based revascularization. Surgical amputation of necrosis was not undertaken due to fear of wound healing difficulties under long-term immunosuppression and impaired tissue perfusion. Intensive wound care and selective debridement were performed. Two patients developed progressive gangrene followed by auto-amputation during a follow-up of 43 and 49 months with continued ambulation and two patients died of unrelated causes 9 and 12 months after diagnosis of CLI. In conclusion, we report a conservative treatment strategy for distal leg necrosis in LTR without surgical amputation and recommend this approach based on our experience.

    A lack of research exploring post-transplant process optimization to reduce readmissions and increasing readmission rates at our center from 2009 to 2013 led to this study, aimed at assessing the effect of patient and process factors on 30-d readmission rates after kidney transplantation. This was a retrospective case-control study in adult kidney transplant recipients. Univariate and multivariate analyses were utilized to assess patient and process determinants of 30-d readmissions. 384 patients were included; 30-d readmissions were significantly associated with graft loss and death (p = 0.001). Diabetes (p = 0.049), pharmacist identification of poor understanding or adherence, and prolonged time on hemodialysis prior to transplant were associated with an increased risk of 30-d readmissions. After controlling for risk factors, readmission rates were only independently predicted by pharmacist identification of patient lack of understanding or adherence regarding post-transplant medications and dialysis exposure for more than three yr (OR 2.3, 95% CI 1.10-4.71, p = 0.026 and OR 2.1, 95% CI 1.22, 3.70, respectively), both of which were significantly modified by history of diabetes. Thirty-d readmissions are attributable to both patient and process-level factors. These data suggest that a lack of post-transplant medication knowledge in high-risk patients drives early hospital readmission. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Diabetic ketoacidosis in patients receiving tacrolimus in the post-transplant setting is rare. We describe two such cases in solid-organ transplant recipients. The first patient, a 17-year-old male, presented with severe diabetic ketoacidosis and was managed with intravenous fluids and insulin infusion. He was a known case of Laurence-Moon-Bardet-Biedl syndrome and had received a renal transplant 2 years ago and was receiving tacrolimus since then. Although diabetic ketoacidosis resolved in 24 hours, large doses of subcutaneous insulin (unto 130 units per day) were needed to keep serum glucose within the normal range. Substitution of tacrolimus with cyclosporine obviated the need for insulin or oral hypoglycaemics. The second patient, a 55-year-old woman, presented with a history of polyuria for 3 days. She had received a hepatic transplant 2 years ago and tacrolimus was being used since then. Mild diabetic ketoacidosis was managed with fluid resuscitation and subcutaneous insulin. Her insulin requirement after an uneventful recovery has been 54 - 70 units per day. Clinicians should be cognizant of the possibility of hyperglycaemic crisis presenting as sudden onset of diabetic ketoacidosis in patients receiving tacrolimus. Use of an alternative calcineurin inhibitor may provide a safer solution to minimize future morbidity in such patients. (author)

    Traumatic experiences are not unusual in pediatric heart transplant (HT) recipients before and after transplantation. Post-traumatic stress symptoms (PTSS) present at the time of transplant evaluation and developing afterward occur with an unknown frequency. We sought to determine the burden of these symptoms in heart transplant patients. We reviewed 51 consecutive HTs between 2003-2007, including 40 primary transplants and 11 re-transplants. Symptoms were present in 17 of the 51 patients (34%) at the time of orthotopic heart transplantation evaluation. None met the criteria for full post traumatic stress disorder. Transplant complications were examined. Nineteen subjects of the total sample had rejection in the first year following transplant. Rejection rates in the first year was 41% for those with PTSS (7 of 17 patients) and 36% for those without (12 of 33 patients) (P=n.s). Of those patients presenting for a second heart transplant, 55% had PTSS at the time of transplant evaluation and/or the peritransplant period; whereas, (28%) undergoing a primary transplant had PTSS. In addition to symptoms resulting from the disease process leading to HT and other prior experiences, the HT itself seems to present a large psychiatric burden on patients. All patients need to be followed before and after HT for signs and symptoms related to PTSS. Future studies should be undertaken to determine if preventative detection and treatment of patients with these PTSS symptoms early can lead to better outcomes.

Improved surgical and medical management has led to significant improvements in post-transplant survival rates with a 1 year and 5 year patient survival of 87% and 73%, respectively. A high mortality rate due to infections during the first post-transplant year persists. Invasive candidiasis is recognized as a significant problem associated with high morbidity and mortality. Recent surveillance data has helped to understand the changes in the epidemiology and the evolving trends in the use of antifungal agents for prophylaxis and treatment combined with the challenges of managing these invasive fungal infections, which has led the transplant community to explore the best management strategies. The emergence of resistant fungi and excess costs in managing these invasive fungal infections has added to the complexities of management. In this context, current perspectives in the management of Candida infections in liver transplant recipients will be reviewed. Keywords: Candida infections, management, liver transplant

    Before performing a clinical, diagnostic, and/or therapeutic action, the doctor is required to provide the patient with a bulk of information defined as informed consent. This expression was used for the first time in 1957 during a court case in California and the two words--informed and consent--are used together to underline the fact that the patient cannot give his or her true consent without first receiving correct information concerning the medical act in question. With regard to the medicolegal aspects governing organ transplants, despite the bulk of detailed work performed by health service workers involved in this surgical field with the aim of preparing adequate informed consent models, this has not yet been accompanied by the necessary legislative development. The informed consent model to be presented to the kidney transplant candidate should include a detailed description of the recipient's comorbidity and should aim at reducing the number of medicolegal actions, which have become more and more frequent in the last few years due to the ever increasing number of patients considered as suitable for transplantation. Informed consent, therefore, should not be a mere bureaucratic formality to be obtained casually, but should be carefully stipulated together with the patient by the transplant surgeon. It is, in fact, an indispensable condition for transforming a potentially illegal action, that is, the violation of an individual's psychophysical integrity, into a legal one.

    Full Text Available Patients with end-stage renal disease (ESRD encounter various challenges following kidney transplantation, which should be managed appropriately. These problems can be partly controlled by considering spirituality as one of the care components. Regarding this, the aim of this study was to investigate the relationship between coping and spiritual health in the renal transplant recipients. This descriptive correlational study was conducted on 169 patients referring to the Organ Transplantation Center at Montasserieh Hospital in Mashhad, Iran. The study population was selected through convenience sampling method. The data were collected using demographic characteristics form, Renal Transplant Coping Scale by Valizadeh et al. (2015, and Spiritual Health Questionnaire developed by Khorashadizadeh et al. (2015. The mean scores of coping and spiritual health were 321.2±15.3 and 123.3±6.2, respectively, which were desirable. There was a significant linear relationship between coping and spiritual health mean scores (P˂0.001, r=0.37. Based on the findings, the reinforcement of spiritual beliefs in patients could be a strategy to promote their coping level.

    To test the accuracy of various physicians' participation in Medicaid models. Primary data on 221 obstetricians and gynecologists in the Chicago area by telephone interviews over a four-month period. These data were combined with secondary data from the American Medical Association Master File (1993) and U.S. Census data (1990). Telephone interviewers posing as the older sisters of a pregnant teenager who is a Medicaid recipient sought information regarding the care provided in a first prenatal care appointment (e.g., appointment duration, tests administered, delivery privileges, appointment availability). A "receptionist helpfulness" variable was developed through pretesting on obstetricians in another city. Inter-interviewer reliability was enhanced through common interview technique education. Only 81 obstetricians (36.7 percent) accepted new Medicaid patients. This finding is lower than previous research on physician participation in Medicaid. There was strong empirical support for both dimensions-cost containment and limited access-of the physicians' receptiveness model, the model introduced with this research. There was limited support for the dual market and residential segregation models of physician participation in Medicaid. It is argued that this study's research design is more accurate in reflecting the barriers that a pregnant Medicaid-eligible patient encounters when seeking office-based prenatal care. As such, combining the physicians' receptiveness model with other physician participation in Medicaid models provides a more complete picture of access barriers to prenatal care for our most needy populations.

    Rhabdomyolysis is a pathological syndrome caused by skeletal muscle cell damage that affects the integrity of the cellular membrane and leads to the release of toxic intracellular constituents into the bloodstream. Although cytomegalovirus (CMV) has rarely been reported as a cause of rhabdomyolysis, CMV infection could be considered as a possible cause because of its clinical significance in kidney transplant recipients (KTRs). We report 2 cases of rhabdomyolysis associated with CMV infection in KTRs. A 64-year-old woman (Case 1) and a 65-year-old man (Case 2), who had each received a kidney from a living unrelated donor, were admitted with complaints of weakness in both legs and myalgia. Laboratory findings revealed highly increased creatine phosphokinase and myoglobinuria. In both cases, no recent alterations of medications had occurred, and other causes of rhabdomyolysis--such as trauma, alcohol, drugs, and electrolyte abnormalities - were excluded. CMV pp65 antigen was positive, and patients were diagnosed with rhabdomyolysis associated with CMV infection. Both patients recovered without complications after ganciclovir treatment. In conclusion, CMV infection should be considered as a possible cause of rhabdomyolysis in KTRs. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Numerous spontaneous pregnancies have been reported in renal transplant recipients; however, only a few pregnancies after the use of assisted reproductive techniques. The authors report a case of renal transplant recipient with secondary infertility who delivered a healthy baby without any complications. The report highlights the importance of minimal stimulation protocol during ovarian stimulation, single embryo transfer, and the need for multispecialty care for these patients. To the best of the authors' knowledge, the present report is the first such case from India and also the second in the world to report a blastocyst transfer among renal transplant recipients.

    Information campaigns to increase tax compliance could be framed in different ways. They can either highlight the potential gains when tax compliance is high, or the potential losses when compliance is low. According to regulatory focus theory, such framing should be most effective when it is congruent with the promotion or prevention focus of its recipients. Two studies confirmed the hypothesized interaction effects between recipients' regulatory focus and framing of information campaigns, with tax compliance being highest under conditions of regulatory fit. To address taxpayers effectively, information campaigns by tax authorities should consider the positive and negative framing of information, and the moderating effect of recipients' regulatory focus.

    Since the 1950s, the number of doctorate recipients has risen dramatically in the United States. In this paper, we investigate whether the longevity of doctorate recipients’ publication careers has changed. This is achieved by matching 1951-2010 doctorate recipients in astrophysics, chemistry, economics, genetics and psychology with rare names in the dissertation database ProQuest to their publications in the publication database Web of Science. Our study shows that post-PhD publication career spans have not changed much in most fields, with the share of doctorate recipients who have published for over twenty years having remained stable over time.

    Recipient adolescent age for non-lung solid-organ transplantation is associated with higher rates of rejection, graft loss and mortality. Although there have been no studies specifically examining adolescent outcomes after lung transplantation (LTx), limited data from the International Society of Heart and Lung Transplantation (ISHLT) Registry suggest that a similar association may exist. Recently, adolescence has been defined as 10 to 24 years of age, taking into account the biologic and sociologic transitions that occur during this age interval. The ISHLT Registry was used to examine the survival outcomes of LTx recipients 10 to 24 years of age between 2005 and 2013. Given the developmental changes that occur in adolescence, survival outcomes for the tertiles of adolescence (10 to 14, 15 to 19 and 20 to 24 years old) were also examined. Adolescents made up 9% (n = 2,319) of the 24,730 LTxs undertaken during the study period. Kaplan-Meier survival estimates at 3 years showed lower adolescent survival (65%) when compared with younger children (73%, p = 0.006) and adults 25 to 34 (75%, p < 0.00001) and 35 to 49 (71%, p < 0.00001) years of age, without a significant survival difference compared with those 50 to 65 years old. Critically, 15- to 19-year-old recipients had the poorest outcomes, with reduced 1-year survival (82%) compared with those 10 to 14 years old (88%, p = 0.02), and reduced 3-year survival (59%) compared with those 10 to 14 (73%, p < 0.00001) and 20 to 24 (66%, p < 0.0001) years old. Adolescent LTx recipients have poorer overall survival when compared with younger children and adults, with those 15 to 19 years old having the highest risk of death. This survival disparity among age groups likely reflects the difficult period of adolescence and its biologic and social transitions, which may influence both immunologic function and adherence.

    Immunosuppressive therapy protects the transplanted organ but predisposes the recipient to chronic infections and malignancies. Transplant patients are at risk of cervical intraepithelial neoplasia (CIN) and cervical cancer resulting from an impaired immune response in the case of primary infection or of reactivation of a latent infection with human papillomavirus of high oncogenic potential (HR-HPV). The aim of this study was to assess the prevalence of HR-HPV cervical infections and CIN in 60 female kidney graft recipients of reproductive age in comparison to that in healthy controls. Cervical swabs were analyzed for the presence of HR-HPV DNA. HR-HPV-positive women remained under strict observation and were re-examined after 24 months for the presence of transforming HR-HPV infection by testing for HR-HPV E6/E7 mRNA. All the HR-HPV-positive patients were scheduled for further diagnostic tests including exfoliative cytology, colposcopy and cervical biopsy. The prevalence of HR-HPV did not differ significantly between the study group and the healthy controls (18% vs 25%, p = 0.37). There was no correlation between HR-HPV presence and the immunosuppresive regimen, underlying disease, graft function or time interval from transplantation. A higher prevalence of HR-HPV was observed in females who had had ≥ 2 sexual partners in the past. Among HR-HPV-positive patients, two cases of CIN2+ were diagnosed in each group. In the course of follow-up, transforming HR-HPV infections were detected in two kidney recipients and in one healthy female. Histologic examination confirmed another two cases of CIN2+ developing in the cervical canal. Female kidney graft recipients of reproductive age are as exposed to HR-HPV infection as are healthy individuals. Tests detecting the presence of HR-HPV E6/E7 mRNA offer a novel diagnostic opportunity in those patients, especially in those cases where lesions have developed in the cervical canal.

    The ability of cord blood transplantation (CBT) to prevent relapse depends partly on donor natural killer (NK) cell alloreactivity. NK effector function depends on specific killer-cell immunoglobulin-like receptors (KIR) and HLA interactions. Thus, it is important to identify optimal combinations of KIR-HLA genotypes in donors and recipients that could improve CBT outcome. We studied clinical data, KIR and HLA genotypes, and NK-cell reconstitution in CBT patients (n = 110). Results were validated in an independent cohort (n = 94). HLA-KIR genotyping of recipient germline and transplanted cord blood (CB) grafts predicted for large differences in outcome. Patients homozygous for HLA-C2 group alleles had higher 1-year relapse rate and worse survival after CBT than did HLA-C1/C1 or HLA-C1/C2 (HLA-C1/x) patients: 67.8% vs 26.0% and 15.0% vs 52.9%, respectively. This inferior outcome was associated with delayed posttransplant recovery of NK cells expressing the HLA-C2-specific KIR2DL1/S1 receptors. HLA-C1/x patients receiving a CB graft with the combined HLA-C1-KIR2DL2/L3/S2 genotype had lower 1-year relapse rate (6.7% vs 40.1%) and superior survival (74.2% vs 41.3%) compared with recipients of grafts lacking KIR2DS2 or HLA-C1 HLA-C2/C2 patients had lower relapse rate (44.7% vs 93.4%) and better survival (30.1% vs 0%) if they received a graft with the combined HLA-C2-KIR2DL1/S1 genotype. Relapsed/refractory disease at CBT, recipient HLA-C2/C2 genotype, and donor HLA-KIR genotype were independent predictors of outcome. Thus, we propose the inclusion of KIR genotyping in graft selection criteria for CBT. HLA-C1/x patients should receive an HLA-C1-KIR2DL2/L3/S2 CB graft, while HLA-C2/C2 patients may benefit from an HLA-C2-KIR2DL1/S1 graft. © 2016 by The American Society of Hematology.

    Pulmonary alveolar macrophages (PAM) from donor rats were intratracheally instilled into recipient rats to determine if donor macrophages were functionally similar to the recipient's own macrophages. Recipient and donor (extrinsic) PAM were equivalent in their ability to phagocytize 1.7 μm and 3.9 μm latex microspheres in vivo and sensitized sheep red blood cells in vitro. Also, the extrinsic PAM appeared functionally equivalent to recipient PAM with respect to ability to translocate into interstitial tissue and migrate to the lung-associated lymph nodes (LALN). The recipient PAN appeared to phagocytize the extrinsic PAM, but the extrinsic PAM did not appear to phagocytize the recipient PAM. This could represent a different degree of physiological coordination of intrinsic and extrinsic PAM activities in the lung. Overall, results indicated that extrinsic PAM can live and function in the lungs of recipient rats, and perform most or all of the functions ascribed to recipient PAM. Results also support the hypothesis that PAM are able to move into the pulmonary interstitium and translocate to the LALM without the involvement of other pulmonary macrophages. (author)

  6. Transplantation of a 2-year-old deceased-donor liver to a 61-year-old male recipient

    Full Text Available The suitable size of a graft is a key element in the success of liver transplantation. A small-for-size liver graft is very likely to sustain a significant degree of injury as a result of ischemia, preservation, reperfusion, and rejection. Usually, small-for-size grafts are a concern in living-donor liver transplantation rather than in deceased-donor liver transplantation. Here, we describe the successful transplantation of a liver from a 2-year-old deceased donor to a 61-year-old male recipient who suffered from liver failure related to hepatitis B. No report of successful deceased-donor liver transplantation with discrepancies between donor and recipient age and size to such an extent has been found in the literature. Despite unusually large discrepancies, with effort in minimizing the ischemic time, revised surgical techniques, and strong regenerative power of the “young” graft, the old patient's liver function gradually returned to normal. This again proves that the definition of a “suitable graft” evolves with time and experience.

  7. In vivo effects of high-dose steroids on nucleic acid content of immunocompetent cells of renal allograft recipients

    High-dose steroids administered to renal allograft recipients for treatment of acute graft rejection episodes may affect cell cycle progression of peripheral blood mononuclear (PBM) cells. DNA synthesis and cellular DNA and RNA contents of PBM cells were measured in 8 patients during clinically stable periods, and in another 10 patients both during acute rejection episodes and during 7 days of administration of high-dose steroids. Improved renal function documented successful reversal of the rejection episodes in the 10 patients. Compared with the stable patients, the rejecting patients had higher numbers of cells undergoing clonal expansion--namely, higher proportions of G1-cells and of proliferating, or S, G2, and M (SG2M) cells. Steroid treatment had no acute effects on proportions of G1 or SG2M cells in vivo or on incorporation of 3 H thymidine by PBM cells in vitro. However, cells in the prereplicative compartment of the cell cycle (G0/1 cells) had significantly lower RNA content within 7 days of treatment with high doses of steroids. The results suggest that steroids do not acutely influence the posttranscriptional synthesis and the contents of nucleic acids of cells undergoing clonal expansion in vivo. The prereplicative phase of allogeneically stimulated PBM cells of renal allograft recipients may therefore be the cell cycle phase most sensitive to steroids in vivo

  20. Augmentation of Recipient Adaptive Alloimmunity by Donor Passenger Lymphocytes within the Transplant

    Directory of Open Access Journals (Sweden)

    Ines G. Harper

    2016-05-01

    Full Text Available Chronic rejection of solid organ allografts remains the major cause of transplant failure. Donor-derived tissue-resident lymphocytes are transferred to the recipient during transplantation, but their impact on alloimmunity is unknown. Using mouse cardiac transplant models, we show that graft-versus-host recognition by passenger donor CD4 T cells markedly augments recipient cellular and humoral alloimmunity, resulting in more severe allograft vasculopathy and early graft failure. This augmentation is enhanced when donors were pre-sensitized to the recipient, is dependent upon avoidance of host NK cell recognition, and is partly due to provision of cognate help for allo-specific B cells from donor CD4 T cells recognizing B cell MHC class II in a peptide-degenerate manner. Passenger donor lymphocytes may therefore influence recipient alloimmune responses and represent a therapeutic target in solid organ transplantation.

    2010-02-01

    The growing need for organs and the scarcity of donors has resulted in an increased use of extended criteria donors. We report a case where a recipient of a cardiac graft was used as an organ donor. Death of the recipient occurred 9 days after transplantation and was attributed to presumed cerebral hemorrhage, which post mortem was diagnosed as invasive aspergillosis of the brain. One recipient of a kidney transplant lost the graft due to infection with Aspergillus fumigatus, whereas prompt initiation of therapy successfully prevented disseminated aspergillosis in the other recipients. Despite the pressure to extend the use of organs by lowering the acceptance criteria, organs should only be accepted if the cause of death of the donors is unequivocally explained.

  2. Donors and Recipients of Living Kidney Donation: A Qualitative Metasummary of Their Experiences

    Directory of Open Access Journals (Sweden)

    Deborah Ummel

    2011-01-01

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

    Studies about the psychosocial issues concerning organ donation and transplantation tend to focus on the experiences of donor or recipient families. Little is known about the part played by correspondence exchanged between these two groups; in particular how they perceive the agency of organ donation. This is the first analysis to address the representation of the act of donation from the viewpoint of both donor and recipient families through interrogation of archived correspondence data, using linguistic techniques. The data was drawn from a collection of letters, from four USA organ procurement organisations, exchanged between donor and transplant recipient families. Donor families consistently linguistically ascribed agency and accountability for donation to the person who died, the donor. For the recipient families, on the other hand, the 'giver' was mainly implied, ambiguous or ascribed to the donor family. © 2016 Foundation for the Sociology of Health & Illness.

    Cochlear implants (CI) are effective in transmitting salient features of speech, especially in quiet, but current CI technology is not well suited in transmission of key musical structures (e.g., melody, timbre). It is possible, however, that sung lyrics, which are commonly heard in real-world music may provide acoustical cues that support better music perception. The purpose of this study was to examine how accurately adults who use CIs (n = 87) and those with normal hearing (NH) (n = 17) are able to recognize real-world music excerpts based upon musical and linguistic (lyrics) cues. CI recipients were significantly less accurate than NH listeners on recognition of real-world music with or, in particular, without lyrics; however, CI recipients whose devices transmitted acoustic plus electric stimulation were more accurate than CI recipients reliant upon electric stimulation alone (particularly items without linguistic cues). Recognition by CI recipients improved as a function of linguistic cues. Participants were tested on melody recognition of complex melodies (pop, country, & classical styles). Results were analyzed as a function of: hearing status and history, device type (electric only or acoustic plus electric stimulation), musical style, linguistic and musical cues, speech perception scores, cognitive processing, music background, age, and in relation to self-report on listening acuity and enjoyment. Age at time of testing was negatively correlated with recognition performance. These results have practical implications regarding successful participation of CI users in music-based activities that include recognition and accurate perception of real-world songs (e.g., reminiscence, lyric analysis, & listening for enjoyment).

    Pulmonary hypertension and right ventricular dysfunction can complicate lung transplant. Pulmonary artery pressures affect outcome are uncertain during wait list. We evaluated changes in wait list pulmonary artery pressures on survival after lung transplant. We queried the United Network for Organ Sharing/Standard Transplant Analysis and Research registry from 1987 to 2012 for all lung transplants. Recipients with unique pulmonary artery pressure measurements upon listing and transplant were included. Mean pulmonary artery pressure was rated as increased (increase > 5 mm Hg), decreased (decrease > 5 mm Hg), or unchanged (variation pulmonary artery pressure during the listing period (P ≤ .0001). In recipients with chronic obstructive pulmonary disease, survival was poorer when mean pulmonary artery pressure was increased than decreased (P ≤ .03). In recipients with primary pulmonary hypertension, survival was poorer when mean pulmonary artery pressure was decreased than increased (P ≤ .02). Proportional hazards analysis showed that increases in mean pulmonary artery pressure independently affected survival (hazard ratio, 0.78; 95% confidence interval, 0.62-0.96). Although the mechanism is unknown, an increase in mean pulmonary artery pressure in patients with chronic obstructive pulmonary disease is associated with poorer survival after lung transplant. In contrast, patients with primary pulmonary hypertension with decreased mean pulmonary artery pressure have poorer survival after lung transplant. In patients with primary pulmonary hypertension, changes in pulmonary artery pressure may be a surrogate for a failing right ventricular function. In chronic obstructive pulmonary disease, the change in pressure suggests an undetermined progressive process. Further study of right ventricular function is warranted to determine the effects of changes in pulmonary artery pressure on lung transplant recipients.

    There is an emerging need to assess the metabolic state of liver allografts especially in the novel setting of machine perfusion preservation and donor in cardiac death (DCD) grafts. High-resolution magic-angle-spinning nuclear magnetic resonance (HR-MAS-NMR) could be a useful tool in this setting as it can extemporaneously provide untargeted metabolic profiling. The purpose of this study was to evaluate the potential value of HR-MAS-NMR metabolomic analysis of back-table biopsies for the prediction of early allograft dysfunction (EAD) and donor-recipient matching. The metabolic profiles of back-table biopsies obtained by HR-MAS-NMR, were compared according to the presence of EAD using partial least squares discriminant analysis. Network analysis was used to identify metabolites which changed significantly. The profiles were compared to native livers to identify metabolites for donor-recipient matching. The metabolic profiles were significantly different in grafts that caused EAD compared to those that did not. The constructed model can be used to predict the graft outcome with excellent accuracy. The metabolites showing the most significant differences were lactate level >8.3 mmol/g and phosphocholine content >0.646 mmol/g, which were significantly associated with graft dysfunction with an excellent accuracy (AUROC lactates  = 0.906; AUROC phosphocholine  = 0.816). Native livers from patients with sarcopenia had low lactate and glycerophosphocholine content. In patients with sarcopenia, the risk of EAD was significantly higher when transplanting a graft with a high-risk graft metabolic score. This study underlines the cost of metabolic adaptation, identifying lactate and choline-derived metabolites as predictors of poor graft function in both native livers and liver grafts. HR-MAS-NMR seems a valid technique to evaluate graft quality and the consequences of cold ischemia on the graft. It could be used to assess the efficiency of graft resuscitation on

    Full Text Available Overweight and obesity are common in subjects after kidney transplantation. On the other hand, features of malnutrition are also frequently recognized in this group of patients. The aim of the study was to evaluate the prevalence of both abnormalities in a cohort of stable kidney recipients and to assess whether obesity precludes malnutrition in transplanted patients. We also investigated associations between the nutritional status, graft function and adipokines concentrations. The study was performed in 80 prevalent kidney transplant patients and in a control group which consisted of 23 healthy volunteers. Body composition (% of fat, lean body mass (LBM, water content was measured by multifrequency bioelectrical impedance (Body Composition Manager. Nutritional status was determined by a 7–point Subjective Global Assessment (SGA, anthropometric measurements and s-albumin concentration. C–reactive protein (CRP, Il–6 and plasminogen activator inhibitor–1 (PAI–1 were used as markers of inflammatory status. Concentration of leptin, adiponectin and visfatin were measured by ELISA. Results: Mean age was 52.4±13.9 years (45 men and 35 women. Diabetes mellitus was present in 29% (n=23 of them. Mean time after transplantation (transplantation vintage was 82.5±56.5 months (median=73 months. Mean eGFR was 41.7±14.9 ml/min (4 points MDRD, BMI was 25.7±4.2. Overweight was present in 41% of the patients and obesity in 14%. On the basis of SGA evaluation, signs of malnutrition were observed in 48% of the subjects. Malnutrition was present in 64% (21/33 of the overweight patients and in 91% (10/11 of the obese patients. Transplantation vintage was directly associated with fat mass and inversely associated with LBM. Malnourished patients (SGA had a longer transplantation vintage. Adiponectin levels were significantly lower in transplanted patients as compared to controls. In multivariate analysis, leptin was an independent predictor of serum

  18. Effect of rapamycin on spleen size in longstanding renal transplant recipients.

    2014-06-01

    Based on evidence available in the literature, rapamycin, a mammalian target of rapamycin (mTOR) inhibitor, but not calcineurin inhibitors (CNIs), has been shown to decrease spleen size. Small spleen, in some instances, is associated with hyposplenism, a condition recently reported in patients with longstanding renal transplant. Accordingly, the effect of immunosuppressive drugs on spleen size was evaluated. Renal transplant recipients (35 taking mTOR and 68 CNI) were included, in whom a standardized investigation of the kidney allograft and spleen with the use of color Doppler ultrasound was performed and a peripheral smear were reviewed for the presence of Howell-Jolly bodies (HJBs). We enrolled 103 patients (64 men; 66 from a deceased donor). The mean age was 47.7 years (range, 23.0-74.0 y). Mean transplant duration was 1,899 days (range, 181-6,883 d). According to the presence of HJBs, the prevalence of hyposplenism was 47.6% for the entire cohort. The differences between the mTOR and CNI groups regarding sex and the presence of HJBs were not statistically significant (P > .05). Age, creatinine, hemoglobin, leukocytes, platelets, and Doppler parameters in spleen and kidney were similar in both groups (P > .05). mTOR patients had a decreased spleen length size (90.09 ± 13.02 mm vs 111.95 ± 18.66 mm; P < .001), a longer transplant duration (3,576 ± 1,594 d vs 1,036 ± 1,369 d; P < .001) and higher serum cholesterol (227.50 ± 38.75 mg/dL vs 182.67 ± 37.74 mg/dL; P < .001) and triglycerides (194.23 ± 79.88 mg/dL vs 148.70 ± 55.54 mg/dL; P = .003) levels compared with the CNI group. A multivariate analysis showed mTOR inhibitor to be the most important predictor of spleen size. In both the mTOR and CNI groups, the comparison between the subgroups of present and absent HJBs did not show any difference. The findings of this study suggest that small spleens in transplant recipients may be linked to treatment with an mTOR inhibitor, although this apparently does

Aim: to make a comparative assessment of the impact of hemofiltration and coupled plasmafiltration and adsorption (CPFA on systemic hemodynamics and alveolar-capillary diffusion, as well as the dynamics of the pro- and antiinflammatory cytokines in patients with sepsis after renal transplantation. Methods and results. The study included 24 recipients. In the main group (n = 14, we used a combination of CPFA and hemofiltration. The patients of the comparison group (n = 10 we used an isolated hemofiltration. In patients of both groups we observed improvement of hemodynamics and lung function. In doing so by the fifth day after the second procedure in patients of the main group the results were significantly better. This effect we mainly associate with a reduction in the activity of the systemic inflammatory response and the rate of progression of sepsis. This is confirmed by the fact that circulating pro- and anti-inflammatory cytokines were expressly removed during the CPFA.Conclusion. As a result of the CPFA and the hemofiltration we observed an increase in mean arterial blood pres- sure, improving gas exchange in the lungs, as well as reducing the need for vasopressor support. In this case, the additional sorption removal of circulating inflammatory mediators reduces the activity of the systemic inflam- matory response, which can significantly increase the effectiveness of the therapy.

    Non-adherence to immunosuppressant medications is an important risk factor for graft dysfunction. To evaluate the effectiveness of adherence-enhancing interventions, we reviewed adherence intervention studies in solid organ transplant recipients (all ages). Using the following databases: PsycINFO, PubMed, Scopus, and ScienceDirect, we identified 41 eligible studies. Only three non-randomized trials showed a possible positive effect on objective indicators of transplant outcomes (such as rejection, liver enzyme levels, kidney function). None of the 21 RCTs showed an improvement in transplant outcomes. Three studies showed a higher rate of adverse events in the intervention group as compared with controls, although this may be related to ascertainment bias. Improvement in adherence as measured indirectly (eg, with electronic monitoring devices) was not aligned with effects on transplant outcomes. We conclude that adherence interventions, to date, have largely been ineffective in improving transplant outcomes. To improve this track record, intervention efforts may wish to concentrate on non-adherent patients (rather than use convenience sampling, which excludes many of the patients who need the intervention), use direct measures of adherence to guide the interventions, and employ strategies that are intensive and yet engaging enough to ensure that non-adherent patients are able to participate. © 2017 John Wiley & Sons A/S.

    New challenges in renal transplantation include using biological information to devise a useful clinical test for discerning high- and low-risk patients for individual therapy and ascertaining the best combination and appropriate dosages of drugs. Based on a 20-gene signature from a microarray meta-analysis performed on 46 operationally tolerant patients and 266 renal transplant recipients with stable function, we applied the sparse Bolasso methodology to identify a minimal and robust combination of six genes and two demographic parameters associated with operational tolerance. This composite score of operational tolerance discriminated operationally tolerant patients with an area under the curve of 0.97 (95% confidence interval 0.94-1.00). The score was not influenced by immunosuppressive treatment, center of origin, donor type, or post-transplant lymphoproliferative disorder history of the patients. This composite score of operational tolerance was significantly associated with both de novo anti-HLA antibodies and tolerance loss. It was validated by quantitative polymerase chain reaction using independent samples and demonstrated specificity toward a model of tolerance induction. Thus, our score would allow clinicians to improve follow-up of patients, paving the way for individual therapy. Copyright © 2017 International Society of Nephrology. All rights reserved.

    Urinary tract infection is the most common type of bacterial infection in kidney transplant procedures, with adverse effects on graft and patient survival. We aimed to evaluate the risk factors of recurrent urinary tract infection in renal transplant recipients and its impact on patient and graft survival. In a cohort of 1019 patients who were transplanted between 2000 and 2010 at Hamed Al-Essa Organ Transplant Center in Kuwait, 86% developed at least 1 episode of urinary tract infection, with only 6.2% of patients having recurrent infections. We compared patients with recurrent urinary tract infections (group 1) with those who had no recurrence (group 2) regarding their risk factors. Patients in group 1 were significantly younger than those in group 2 (34.9 ± 23 vs 42.8 ± 16 y; P urinary tract infections (P infections were significantly more prevalent among group 1 (10.8% vs 3.8%; P = .008). Long-term graft outcome (functioning and failed) were 78.5% and 21.5% in group 1 versus 85.1% and 13.9% in group 2 (P = .18). Patient outcomes (living and deceased donors) were 98.4% and 1.6% in group 1 versus 95.7% and 4.3% in group 2 (P = .187). Adult females, thymoglobulin induction, pretransplant urologic problems, and hepatitis C infection were the risk factors of recurrent urinary tract infection among our renal transplant patients. However, recurrence did not adversely affect graft or patient survival.

    Several nonimmunologic risk factors for late renal graft loss (RGL) are also known components of metabolic syndrome (MS). We aimed to study MS as a risk factor for RGL. Also, the effect of statin treatment in reducing renal risk in renal transplant recipients (RTRs) with MS was studied. Nondiabetic RTRs (n=1,706) from the ALERT trial were followed for 7-8 years. MS was defined according to National Cholesterol Education Program Adult Treatment Panel III definition with waist girth replaced by BMI ≥30 (calculated as kg/m(2)). Renal end points included death-censored RGL and graft loss or doubling of serum creatinine. During the follow-up, 284 patients experienced RGL, and there were 343 cases of graft loss or doubling of serum creatinine. Those with MS had increased risk for RGL (relative risk = 1.28, 95% confidence interval, 1.00-1.63; p=0.047), but not for the combined end point. After adjustment for other known and potential risk factors, MS was no longer associated with increased risk for RGL. The association between MS and RGL risk was attenuated once adjustment for creatinine was made. Statin treatment did not reduce the risk for renal end points in RTRs with or without MS. MS had no independent association with RGL risk. Adjustment for renal function attenuated the association between MS and RGL.

    Full Text Available One of the most intriguing aspects of human communication is its turn-taking system. It requires the ability to process on-going turns at talk while planning the next, and to launch this next turn without considerable overlap or delay. Recent research has in-vestigated the eye movements of observers of dialogues to gain insight into how we process turns at talk. More specifically, this research has focused on the extent to which we are able to anticipate the end of current and the beginning of next turns. At the same time, there has been a call for shifting experimental paradigms exploring social-cognitive processes away from passive observation towards on-line processing. Here, we present research that responds to this call by situating state-of-the-art tech-nology for tracking interlocutors’ eye movements within spontaneous, face-to-face conversation. Each conversation involved three native speakers of English. The anal-ysis focused on question-response sequences involving just two of those participants, thus rendering the third momentarily unaddressed. Temporal analyses of the un-addressed participants’ gaze shifts from current to next speaker revealed that un-addressed participants are able to anticipate next turns, and moreover, that they often shift their gaze towards the next speaker before the current turn ends. However, an analysis of the complex structure of turns at talk revealed that the planning of these gaze shifts virtually coincides with the points at which the turns first become recog-nizable as possibly complete. We argue that the timing of these eye movements is governed by an organizational principle whereby unaddressed participants shift their gaze at a point that appears interactionally most optimal: It provides unaddressed participants with access to much of the visual, bodily behavior that accompanies both the current speaker’s and the next speaker’s turn, and it allows them to display recipiency with regard to

    Blood pressure (BP) control at home is difficult when managed only with office blood pressure monitoring (OBPM). In this prospective study, the reliability of BP measurements in renal transplant patients with OBPM and home blood pressure monitoring (HBPM) was compared with ambulatory blood pressure monitoring (ABPM) as the gold standard. Adult patients who had living-related renal transplantation from March 2007 to February 2008 had BP measured by two methods; OBPM and ABPM at pretransplantation, 2(nd), 4(th), 6(th), and 9(th) months and all the three methods: OBPM, ABPM, and HBPM at 6 months after transplantation. A total of 49 patients, age 35 ± 11 years, on prednisolone, tacrolimus, and mycophenolate were evaluated. A total of 39 were males (79.6%). Systolic BP (SBP) and diastolic BP (DBP) measured by OBPM were higher than HBPM when compared with ABPM. When assessed using OBPM and awake ABPM, both SBP and DBP were significantly overestimated by OBPM with mean difference of 3-12 mm Hg by office SBP and 6-8 mm Hg for office DBP. When HBPM was compared with mean ABPM at 6 months both the SBP and DBP were overestimated by and 7 mm Hg respectively. At 6 months post transplantation, when compared with ABPM, OBPM was more specific than HBPM in diagnosing hypertension (98% specificity, Kappa: 0.88 vs. 89% specificity, Kappa: 0.71). HBPM was superior to OBPM in identifying patients achieving goal BP (89% specificity, Kappa: 0.71 vs. 50% specificity Kappa: 0.54). In the absence of a gold standard for comparison the latent class model analysis still showed that ABPM was the best tool for diagnosing hypertension and monitoring patients reaching targeted control. OBPM remains an important tool for the diagnosis and management of hypertension in renal transplant recipients. HBPM and ABPM could be used to achieve BP control.

    Liver transplant recipients are at an increased risk for liver failure when infected with hepatitis A virus (HAV) and hepatitis B virus (HBV). Therefore, it is important to vaccinate these individuals. The aim of the study was to evaluate how well liver transplanted patients in our unit were protected against HAV and HBV infection. Furthermore we investigated the vaccination rate and the antibody response to vaccination in these liver transplanted patients. Patients liver transplanted from January 2007 until August 2010 with a posttransplant check-up during the period March-November 2010 were included (n = 51). Information considering diagnose, date of transplantation, Child-Pugh score, and vaccination were collected from the patient records. Anti-HAV IgG and anti-HBs titers in serum samples were analyzed and protective levels were registered. Of the patients 45% were protected against hepatitis A infection and 29% against hepatitis B infection after transplantation. Only 26% were vaccinated according to a complete vaccination schedule and these patients had a vaccine response for HAV and HBV of 50% and 31%, respectively. An additional 31% received ≥ 1 doses of vaccine, but not a complete vaccination and the vaccine response was much lower among these patients, stressing the importance of completing the vaccination schedule. Even when patients were fully vaccinated, they did not respond to the same degree as healthy individuals. Patients seemed to be more likely to respond to a vaccination if they had a lower Child-Pugh score, suggesting that patients should be vaccinated as early as possible in the course of their liver disease.

    To describe current opioid-tapering practice, patient pain levels and withdrawal symptoms, and nurse documentation during opioid tapers. Descriptive, exploratory, prospective, quantitative, and qualitative. A 32-bed blood and marrow transplant unit in a large, tertiary U.S. care center. 45 blood and marrow transplant recipients between the ages of 7-64. Types of transplant were autologous, allogeneic, and unrelated donor marrow; peripheral blood stem cell; and umbilical cord blood. In daily interviews, patients reported pain levels and withdrawal symptoms during opioid tapers. Demographic, medication, and nurse documentation data were obtained from patient hospital records. Taper length, daily opioid dosage, pain, withdrawal symptoms, and nurse documentation. Length of taper ranged from 1-17 days (X = 6.53, SD = 4.26). Analysis of variance indicated no difference by disease or transplant type in length of taper, cumulative opioids given pretaper or during taper, or number of self-reports of withdrawal symptoms. Daily changes in nurse-administered opioid dosage during tapers ranged from a decrease of 67% to an increase of 14%. Children received significantly more opioids/kg during taper than adults. Means of adults' and children's self-reports of pain were low. The means of patient-reported withdrawal symptoms were highest on taper days two through six. Nurse documentation was sparse. Daily taper rates vary widely, pain is well managed, and most patients experience several withdrawal symptoms. Use of an opioid-taper guideline may promote consistency of tapering while not increasing levels of pain or withdrawal symptoms.

    Conclusions: Cryptococcosis is a serious infection among kidney transplant recipients in mainland China. It has unique characteristics, such as a relatively long time to onset after kidney transplantation, and diverse clinical manifestations. Treatment with intrathecal injection of amphotericin B is considered effective for central nervous system involvement. The findings of this study also highlight the urgent need for multicenter, prospective, and multidisciplinary clinical studies and education on cryptococcosis in kidney transplant recipients in China.

    Information provided by health professionals to potential donors and recipients is essential for an autonomous and objective decision to make a living kidney donation. To determine the characteristics of the information received by living kidney donors and recipients, to find out their socio-sanitary profile, their socio-demographics, financial and labour characteristics, health and the caregiving activity of these donors and recipients. Observational, descriptive and cross-sectional study of the population of living kidney donors and recipients from the University Hospitals Puerta del Mar (Cádiz), Virgen del Rocío (Seville), and the University Hospital Complex of Granada, between 08/04/2014 and 08/06/2015. According to the 40 living kidney donors and their 40 recipients surveyed, it is mainly nephrologists who make people aware and provide information about living kidney donation. Almost half of recipients require more information so the evaluation processes and pre-donation information should be updated. In general, the living kidney donor is female, aged 50, with primary/secondary education, lives with a partner and is related to the kidney recipient. Also, the living kidney donor is in paid employment, is overweight, perceives her health as very good or good, and does not smoke or drink alcohol. However, the typical living kidney recipient is male, aged 44 and has completed secondary school studies and vocational training. Furthermore, he does not work, perceives his health as good or regular, and he is an independent person for activities of daily living. Copyright © 2017 Sociedad Española de Nefrología.

    Full Text Available Abstract Background Guidelines for safe gamete donation have emphasised donor screening, although none exist specifically for testing oocyte recipients. Pre-treatment assessment of anonymous donor oocyte IVF treatment in Ireland must comply with the European Union Tissues and Cells Directive (Directive 2004/23/EC. To determine the effectiveness of this Directive when applied to anonymous oocyte recipients in IVF, we reviewed data derived from selected screening tests performed in this clinical setting. Methods Data from tests conducted at baseline for all women enrolling as recipients (n = 225 in the anonymous oocyte donor IVF programme at an urban IVF referral centre during a 24-month period were analysed. Patient age at programme entry and clinical pregnancy rate were also tabulated. All recipients had at least one prior negative test for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis performed by her GP or other primary care provider before reproductive endocrinology consultation. Results Mean (±SD age for donor egg IVF recipients was 40.7 ± 4.2 yrs. No baseline positive chlamydia, gonorrhoea or syphilis screening results were identified among recipients for anonymous oocyte donation IVF during the assessment interval. Mean pregnancy rate (per embryo transfer in this group was 50.5%. Conclusion When tests for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis already have been confirmed to be negative before starting the anonymous donor oocyte IVF sequence, additional (repeat testing on the recipient contributes no new clinical information that would influence treatment in this setting. Patient safety does not appear to be enhanced by application of Directive 2004/23/EC to recipients of anonymous donor oocyte IVF treatment. Given the absence of evidence to quantify risk, this practice is difficult to justify when applied to this low-risk population.

    There is a high prevalence of non-adherence to immunosuppressants in kidney transplant recipients. Although limited health literacy is common in kidney recipients and is linked to adverse outcomes in other medical populations, its effect on medication adherence in kidney transplant recipients remains poorly understood. The objective was to investigate the effect of lower health literacy on immunosuppressant adherence. Kidney recipients who were at least 6 months post-transplant and outpatients of Vancouver General Hospital in B.C., Canada were recruited through invitation letters. A total of 96 recipients completed the Health Literacy Questionnaire, which provides a multifactorial profile of self-reported health literacy and the Transplant Effects Questionnaire-Adherence subscale measuring self-reported immunosuppressant adherence. Hierarchical linear regression was used to analyze the association between health literacy and adherence after controlling for identified risk factors of non-adherence. Our sample was on average 53 years old, 56% male and 9 years post-transplant. Kidney recipients reported low levels of health literacy on scales measuring active health management and critical appraisal of information and 75% reported non-perfect adherence. Worse adherence was associated with poorer overall health literacy (Δ R 2 = 0.08, P = 0.004) and lower scores on six of nine of the health literacy factors. Poorer health literacy is associated with lower immunosuppressant adherence in adult kidney transplant recipients suggesting the importance of considering a recipient's level of health literacy in research and clinical contexts. Medication adherence interventions can target the six factors of health literacy identified as being risk factors for lower medication adherence.

    2017-08-01

    Vaccine-preventable diseases, especially influenza, varicella, herpes zoster, and invasive pneumococcal infections, continue to lead to significant morbidity and mortality in solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients. We highlight guideline recommendations for the use of key vaccines in SOT and HSCT recipients and to review the latest evidence and developments in the field. Physicians should vaccinate individuals with end-stage organ disease, as vaccine seroresponse rates are higher pretransplantation. Most live attenuated vaccines continue to be contraindicated post-transplantation, but there are emerging safety profile and efficacy data to support the use of specific live attenuated vaccines, such as measles, mumps, and rubella in pediatric liver or kidney transplant recipients who are on low-level maintenance immunosuppression and without recent history of allograft rejection. An inactivated subunit varicella zoster virus vaccine is currently awaiting US Food and Drug Administration approval. While we await the safety profile and efficacy data of this subunit vaccine in transplant recipients, it will likely benefit immunocompromised individuals, including transplant recipients, because the live attenuated herpes zoster vaccine is currently contraindicated in transplant recipients and transplantation candidates receiving immunosuppression. There is currently no evidence that vaccines lead to allograft rejection in SOT recipients. Household contacts of SOT and HSCT recipients should be vaccinated per the Advisory Committee on Immunization Practices schedule and recommendations. Immunizations remain underutilized in transplantation patients. Although efficacy of vaccines in SOT and HSCT may be suboptimal, partial protection is preferred over no protection.
