    Fractures are associated with high morbidity and are a major concern for kidney transplant recipients. No comparative analysis has yet been conducted between countries in the contemporary era to inform future international prevention trials. Data were obtained from the Hospital Episode Statistics and the Statewide Planning and Research Cooperative databases on all adult kidney transplants performed in England and New York State from 2003 to 2013, respectively, and on posttransplant fracture-related hospitalization from 2003 to 2014. Our analysis included 18 493 English and 11 602 New York State kidney transplant recipients. Overall, 637 English recipients (3.4%) and 398 New York State recipients (3.4%) sustained a fracture, giving an unadjusted event rate of 7.0 and 5.9 per 1000 years, respectively (P = .948). Of these, 147 English (0.8%) and 101 New York State recipients (0.9%) sustained a hip fracture, giving an unadjusted event rate of 1.6 and 1.5 per 1000 years, respectively (P = .480). There were no differences in the cumulative incidence of all fractures or hip fractures. One-year mortality rates after any fracture (9% and 11%) or after a hip fracture (15% and 17%) were not different between cohorts. Contemporaneous English and New York State kidney transplant recipients have similar fracture rates and mortality rates postfracture.

    2009-12-01

    Solid organ and hematopoietic stem cell transplant recipients are uniquely predisposed to develop clinical illness, often with increased severity, due to a variety of common and opportunistic viruses. Patients may acquire viral infections from the donor (donor-derived infections), from reactivation of endogenous latent virus, or from the community. Herpes viruses, most notably cytomegalovirus and Epstein Barr virus, are the most common among opportunistic viral pathogens that cause infection after solid organ and hematopoietic stem cell transplantation. The polyoma BK virus causes opportunistic clinical syndromes predominantly in kidney and allogeneic hematopoietic stem cell transplant recipients. The agents of viral hepatitis B and C present unique challenges particularly among liver transplant recipients. Respiratory viral illnesses due to influenza, respiratory syncytial virus, and parainfluenza virus may affect all types of transplant recipients, although severe clinical disease is observed more commonly among lung and allogeneic hematopoietic stem cell transplant recipients. Less common viral infections affecting transplant recipients include those caused by adenoviruses, parvovirus B19, and West Nile virus. Treatment for viruses with proven effective antiviral drug therapies should be complemented by reduction in the degree of immunosuppression. For others with no proven antiviral drugs for therapy, reduction in the degree of immunosuppression remains as the sole effective strategy for management. Prevention of viral infections is therefore of utmost importance, and this may be accomplished through vaccination, antiviral strategies, and aggressive infection control measures.

    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.

    Full Text Available Aim. To perform comparative analysis of the diagnostic efficacy of sCD40L, PDGF-BB, VEGF-A and ST2 in recipients with cardiac rejection in different periods after transplantation. Materials and methods. The study included 144 cardiac recipients aged from 12 to 71 (mean age 44 ± 14 years old, among those 112 were men. Venous blood plasma taken on the same day with endomyocardial biopsy was used for the study. The concentrations of soluble CD40 ligand (sCD40L, vascular endothelial growth factor (VEGF-A, platelet-derived growth factor (PDGF-BB were measured using xMAP technology. The concentrations of ST2 were measured by ELISA. Results. Men had significantly higher levels of ST2 and VEGF-A compared to women (p = 0.03. No correlation was found between the levels of biomarkers (sCD40L, PDGF-BB, VEGF-A, ST2 and age, diagnosis before transplantation, presence of arterial hypertension and diabetes mellitus. Comparative analysis of the biomarkers’ levels didn’t show significant difference between patients with heart transplant rejection and without it in the first month and in the first year after transplantation. The ST2 level was significantly higher in patients with heart rejection (p = 0.01 in the long term period (1–5 years after transplantation compared to patients without rejection. Relative risk of cardiac transplant rejection was significantly higher in patients with high (>22.8 ng/ml ST2 level (RR = 2.59 ± 0.33; Se – 35%, Sp – 93%. However, its combination with other biomarkers improved their diagnostic value. Relative risk for panel including ST2, VEGF-A and PDGF-BB 3.47 ± 0.55, Se – 57%, Sp – 91%; relative risk for panel including ST2, sCD40L and PDGF-BB was 3.75 ± 0.59, Se – 50%, Sp – 92%. The highest diagnostic efficacy for the heart transplant rejection was reached by a panel of biomarkers that included ST2 and PDGF-BB (RR = 5.0 ± 0.56 [95% CI 1.68–14.92], Se – 63%, Sp – 94%.

    Renal transplant provides a long-term survival. Hearing impairment is a major factor in subjective health status. Status of hearing and the cause of hearing impairment in the pediatric renal transplant group have not been evaluated. Here, we studied to evaluate hearing status in pediatric renal transplant patients and to determine the factors that cause hearing impairment. Twenty-seven pediatric renal transplant recipients were investigated. All patients underwent audiologic assessment by means of pure-tone audiometry. The factors on hearing impairment were performed. Sensorineural hearing impairment was found in 17 patients. There was marked hearing impairment for the higher frequencies between 4000 and 8000 Hz. Sudden hearing loss developed in 2 patients, 1 of them had tinnitus. Decrease of speech understanding was found in 8 patients. The cyclosporine level was significantly high in patients with hearing impairment compared with group without hearing impairment. Cyclosporine levels also were found to be statistically significantly high when compared with the group with decrease of speech understanding and the group without decrease of speech understanding. Similar relations cannot be found between tacrolimus levels and hearing impairment and speech understanding. Sensorineural hearing impairment prevalence was high in pediatric renal transplant recipients when compared with the general population of children. Cyclosporine may be responsible for causing hearing impairment after renal transplant. We suggest that this effect is a dose-dependent toxicity.

    Renal transplantation with a well-functioning graft leads to a rapid restoration of endocrine and sexual functions. The aim of this study was to examine our experience with pregnancies among renal transplant patients, particularly with regard to their impact on graft function. We analyzed 10 pregnancies in 7 renal transplant recipients for long-term graft outcomes in terms of clinical and biological data. The mean patient age was 28.5 +/- 4 years. They all received a living donor kidney. The time between transplantation and the onset of pregnancy was 33.4 +/- 23.2 months. Regarding the immunosuppressive therapy, all patients received steroids and cyclosporine; 4 patients received in addition azathioprine and 2 received mycophenolate mofetil that was changed at 1 month before conception to azathioprine. There was no significant difference between the serum creatinine before and during pregnancy. We did not observe any acute rejection episode. Pregnancy complications were preclampsia in 1 case, hypertension in 1 case, urinary tract infection in 2 cases, and anemia in 80% of patients during the third trimester. Premature rupture of membranes occurred in 1 case and preterm delivery in 2 cases. Two cases of neonatal death were registered. Cesarean section was performed in 50% of cases. The follow-up revealed 2 cases of chronic rejection. A multidisciplinary approach is necessary for pregnancy which generally occurs at 2 years after kidney transplantation.

    Antithymocyte globulin rabbit (r-ATG) has been used for the treatment and prevention of acute rejection in renal transplant recipients (RTR). Current manufacturer recommendations for r-ATG dictate the need for administration through a high-flow vein (central line). Previous studies have shown peripheral administration of r-ATG to be safe; however, these studies suggest the co-administration of heparin and hydrocortisone and did not compare the infusion-site reaction rates to a control group. A retrospective analysis was conducted of adult RTR receiving r-ATG or basiliximab between January 2004 and October 2006. Each agent was administered through a dedicated peripheral line. The primary endpoint was the incidence of infusion-site reactions. Other endpoints included the need to replace the intravenous catheter and the incidence of systemic thrombosis within 1 month of transplantation. During the study period, 152 peripheral infusions of r-ATG and 92 peripheral infusions of basiliximab were administered. No difference in infusion-site reactions was noted between the groups. There was also no difference either in the need for peripheral line replacement or the rates of systemic thrombosis. Peripheral administration of r-ATG is safe and can be infused without concomitant heparin and hydrocortisone. This method of r-ATG infusion was shown to be as safe as peripherally administered basiliximab.

    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.

    Organ transplant recipients have a higher incidence of skin cancer. This risk is magnified over time and with continued exposure to immunosuppression. Skin cancer in nonwhite patients is associated with greater morbidity and mortality owing to diagnosis at a more advanced stage, which suggests that nonwhite organ transplant recipients are at even higher risk. To describe demographic and clinical factors and the incidence of skin cancer in nonwhite organ transplant recipients. We performed a retrospective medical record review of patients who were organ transplant recipients (154 were white and 259 nonwhite [black, Asian, Hispanic, Pacific Islander]) seen from November 1, 2011, to April 18, 2016 at an academic referral center. Variables were analyzed and compared between racial groups, including sex, age, race/ethnicity, Fitzpatrick type, type and location of skin cancer, type of organ transplanted, time to diagnosis of skin cancer after transplantation, and history of condyloma acuminata and/or verruca vulgaris. Most of the 413 patients (62.7%) evaluated were nonwhite organ transplant recipients; 264 were men, and 149 were women. Their mean (SD) age was 60.09 (13.59) years. Nineteen skin cancers were identified in 15 patients (5.8%) representing 3 racial/ethnic groups: black (6 patients), Asian (5), and Hispanic (4). All squamous cell carcinomas in blacks were diagnosed in the in situ stage, located on sun-protected sites, and occurred in patients whose lesions tested positive for human papilloma virus (HPV) and/or who endorsed a history of condyloma acuminata or verruca vulgaris. Most skin cancers in Asians were located on sun-exposed areas and occurred in individuals who emigrated from equatorial locations. Nonwhite organ transplant recipients are at risk for developing skin cancer posttransplantation. Follow-up in a specialized transplant dermatology center and baseline total-body skin examination should be part of posttransplantation care in all organ

    Our objective was to compare the outcomes of dual kidney transplanataion (DKT) to single kidney transplantation (SKT) performed with grafts from expanded criteria donors (ECD) in recipients ≥65 years, focusing on surgical complications. All kidney transplantations (KT) performed between 2006 and 2014 in our institution were analysed. DKT was indicated according to the criteria of the French national Agence de la Biomedecine. Thirty-nine DKT and 155 SKT were included, with a median follow-up of 36 and 26.5 months, respectively. The rate of early surgical revisions was not significantly higher after DKT (23.1% vs 15.5% (P = 0.2593)) but more venous graft thromboses (12.8% vs 3.2% (P = 0.02)) were reported. The glomerular filtration rate (GFR) 24 months after KT was significantly higher after DKT (45.0 ± 16.3 vs 39.8 ± 13.8 ml/min/1.73m 2 ; P = 0.04) and allowed shorter waiting time without a significant increased risk of surgical revision, excepted for venous graft thrombosis, more frequent after DKT. Graft survivals were not significantly different and GFR was higher after DKT. DKT seems to remain an appropriate strategy to address the growing graft shortage in elderly patients. © 2018 Steunstichting ESOT.

    End-stage renal disease (ESRD) in children is associated with impaired neurocognitive function and development. However, data on factors associated with neurocognitive dysfunctions in children with kidney transplants are limited. We conducted a cross-sectional analysis comparing cognitive functions (using the Woodcock-Johnson International Edition, WJIE) in 35 kidney transplant and 35 healthy control children. Data on laboratory measurements, comorbidities, and social characteristics were collected. Transplant children had significantly worse scores on the intelligence quotient (IQ) test compared with controls [Full Scale IQ score 85 (26) vs 107 (10), p 9 months) were associated with lower test scores. Age-standardized duration of hospitalization was inversely correlated with IQ (r = -0.46, p <0.01) and was an independent significant predictor (Beta = -0.38, p = 0.02) of IQ scores in transplanted children. Child kidney transplant recipients have neurocognitive function impairments that are associated with markers of socioeconomic status (SES) and factors related to disease severity.

    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.

    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.

    One of the fundamental challenges in managing pediatric renal transplant recipient is to ensure normal growth and development. The goal of renal transplant is not just to prolong life but to optimize quality of life. Short stature during childhood may be associated with academic underachievement and development of comorbidities such as attention deficit hyperactivity disorder, learning disability, and mood disorders. The most important factors affecting growth are use of corticosteroids, allograft function, and age and height deficit at the time of transplant. Aggressive conservative management of chronic renal failure and early use of growth hormone therapy will help in optimizing height at time of transplant. Early transplant, steroid minimization or withdrawal, and growth hormone therapy will help in achieving normal adult height in a majority of renal post transplant population. Steroid avoidance to achieve good growth still needs to be validated.

    Full Text Available To evaluate the prevalence, risk factors, possible etiology, prognosis and management of proteinuria in renal transplant recipients, we studied 435 adult renal transplant recipient patients randomly selected from our center; 394 patients were reviewed retrospectively and 41 patients were followed-up prospectively for a period of one year. The patients were classified into three groups according to the results of urinalysis and spot urinary albumin creatinine ratio: Group A patients with normoalbuminuria; Group B patients with microalbuminuria; and Group C patients with macroalbuminuria. Persistent post-transplantation proteinuria was detected in 125 (28.8% patients. The etiology of post-transplantation proteinuria included chronic allograft dysfunction in 44 (35.2% patients, acute rejection in 40 (32% patients, transplant glomerulopathy in eight (6.4% patients, glomerular disease in 16 (12.8% patients and other etiology in 17 (13.6% patients. Proteinuric patients demonstrated significantly lower graft survival rates than did those without proteinuria (48.3% versus 51.7%, respectively; P = 0.017; Risk Ratio = 0.403; 95% confidence interval 0.188-0.862. We conclude that proteinuria is prevalent after kidney transplant in our population, and that it is most commonly associated with chronic allograft nephropathy, transplant glomerulopathy, glomerulonephritis and acute rejection. Post-transplant proteinuria is associated with decreased allograft survival.

    Although low quality of sleep has been reported in kidney transplant patients with functioning allografts, there are no previous studies investigating the dreams of these patients. We aimed to investigate the differences in dream anxiety level between renal transplant patients and healthy control subjects. We also planned to compare depression and anxiety symptoms, sleep quality and sleepiness level between these two groups. Twenty-two living-donor renal transplant recipients followed at an outpatient nephrology clinic and 22 healthy controls were enrolled in this observational cross-sectional study. Sociodemographic Data Collection Form, and the Van Dream Anxiety Scale (VDAS), the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), Beck Depression and Anxiety Inventories were used for the assessment of the necessary features. Hemoglobin (Hb), blood urea nitrogen (BUN), creatinine (Cr) and glucose levels were measured. There were no significant differences between the groups in terms of dream anxiety (p = 0.45), depression (p = 0.76), sleep quality (p = 0.8), insomnia severity (p = 0.08) and Hb (p = 0.11) and glucose levels (p = 0.14). Although, BUN (p = 0.00) and creatinine (p = 0.00) levels differed significantly between the two groups, both parameters were found to be within their normal range. In our study, chronic renal failure patients with a successful kidney transplant were found to be able to completely return to normal in terms of metabolic parameters, sleep quality and mood. Similar levels of dream anxiety are also consistent with these findings.

    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

    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.

    To review the etiology, treatment, and preventive strategies of hyperuricemia and gout in kidney transplant recipients. Primary literature was obtained via Medline (1966-June 2003). Studies evaluating treatment and prevention of hyperuricemia and gout in kidney transplantation were considered for evaluation. English-language studies were selected for inclusion. Approximately 14,000 kidney transplantations were performed in the United States in 2003, and of those transplant recipients, nearly 13% will experience a new onset of gout. The prevalence of hyperuricemia is even greater. There are several mechanisms by which hyperuricemia and gout develop in kidney transplant recipients. Medication-induced hyperuricemia and renal dysfunction are 2 of the more common mechanisms. Prophylactic and treatment options include allopurinol, colchicine, corticosteroids, and, if absolutely necessary, nonsteroidal antiinflammatory drugs. It is generally recommended to decide whether the risks of prophylactic therapy and treatment outweigh the benefits. Often, the risk of adverse events associated with agents to treat these ailments tends to outweigh the benefits; therefore, treatment is usually reserved for symptomatic episodes of acute gout. Practitioners must also decide if changes in immunosuppressive regimens may be of benefit on a patient-by-patient basis.

    Full Text Available Renal transplantation is ideal treatment of chronic renal failure. Pulmonary infection is a common and serious post transplant infection requiring hospitalization and is associated with high mortality. Increased susceptibility to infection is due to a decrease in the patients' immunological response caused by immunosuppression through drug administration, and by other influences."nMaterials and Methods: This study was case series and prospective, from July 2001 to July 2002 in Imam Khomeini hospital of Tehran."nResults: 164 renal transplant recipients were studied, 14 patients (8.5% had pulmonary infection, 11 of them (78.6% were female and 3 (21.4% were male. The mean age of them was 42.6 years. The patients were followed up for 9 to 12 months. All patients were on triple immunosuppressive regimens. The interval between transplantation and the appearance of pneumonia was 2 months to 10 years. The time of beginning infection in 3 cases (21.4% was between 1 to 6 months post transplantation, 11 cases (78.6% were occurred beyond 6 months after transplantation. In 7 cases (50%, pulmonary infection was occurred during first year after transplantation. None of the 14 patients developed pulmonary infection in first month after transplantation. BAL were used in 6 cases (42.8% of pulmonary infection, and organism were detected in 5 of them (83.3%. The most common clinical feature was fever. Six cases were due to mycobacterium tuberculosis (42.9%, this organism was the most common ethiology of pneumonia. In this study tuberculosis was seen in 3.6% of renal transplant recipients. One patient had pulmonary mucormycosis. All patients with pulmonary TB were cured, and other cases with unknown case, were cured with empirical treatment."nConclusion: Our finding indicate the invasive diagnostic procedures are required in order to earlier and reliable diagnosis and then better outcome of transplantation."n"n"n"n"n"n"n

    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)

    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

    ABSTRACT. Anemia has long been known to be a complication of end-stage renal disease (ESRD), and it has been linked to cardiovascular morbidity and mortality. Although kidney transplant recipients (KTR) are prone to experiencing cardiovascular outcomes, little is known about the epidemiology of anemia in this population. With few exceptions, studies to date have not fully evaluated the associations between posttransplant anemia (PTA) and medications commonly used in KTR, particularly immunosuppressant drugs, angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB). The authors aimed to specifically investigate possible associations between these drugs and PTA. Detailed medical information was retrospectively collected on 374 consecutive KTR from our transplant clinic. Univariate/multivariate linear regression models were used to test for associations between hematocrit (HCT) and other covariates, and logistic regression models were used to detect independent predictors of PTA, defined as HCT <33%. The mean time since transplantation was 7.7 yr, and mean creatinine was 2.2 mg/dl. The prevalence of PTA was 28.6%. Ten percent of all patients were on erythropoietin therapy, but only 41.6% of patients whose HCT was <30 received this treatment. From multivariate analyses, the authors found that female gender and lower renal function were associated with lower HCT (both P < 0.001). Patients on ACEI had significantly lower HCT (P = 0.005) compared with patients without such treatment. In addition, a significant curvilinear dose-response relationship was found between ACEI dose and HCT. Among the immunosuppressant drugs, mycophenolate mofetil (P = 0.05) and tacrolimus (P = 0.02) were associated with a lower HCT. The authors conclude that PTA is prevalent and undertreated in KTR. Several medications that are possibly modifiable correlates of PTR deserve further study.

    To review available data describing the epidemiology, outcomes, prevention, and treatment of influenza virus in the solid organ transplant population and to evaluate the strengths and limitations of the current literature, with a focus on literature reviewing annual influenza strains and the recent pandemic novel influenza A/H1N1 strain. A systematic literature search (July 1980-June 2011) was performed via PubMed using the following key words: influenza, human; influenza; novel influenza A H1/N1; transplantation; solid organ transplantation; kidney transplant; renal transplant; lung transplant; heart transplant; and liver transplant. Papers were excluded if they were not written in English or were animal studies or in vitro studies. Data from fully published studies and recent reports from international conferences were included. The influenza virus presents a constant challenge to immunocompromised patients and their health care providers. The annual influenza strain introduces a highly infectious and pathogenic risk to solid organ transplant recipients. In 2009, the World Health Organization declared a pandemic as a result of a novel influenza A/H1N1 strain. The pandemic introduced an additional viral threat to solid organ transplant patients at increased risk for infectious complications. The mainstay for prevention of influenza infection in all at-risk populations is appropriate vaccination. Antiviral therapies against influenza for chemoprophylaxis and treatment of infection are available; however, dosing strategies in the solid organ transplant population are not well defined. The solid organ transplant population is at an increased risk of severe complications from influenza infection. Identifying risks, preventing illness, and appropriately treating active infection is essential in this patient population.

    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.

    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.

    We present a case of ocular syphilis after a renal transplantation involving progressive vision loss without clinically identifiable ocular disease. Electroretinography showed signs of ischemia, especially in the internal retina. A serological test was positive for syphilis. Lumbar puncture revealed lymphocytic meningitis and a positive serologic test for syphilis in the cerebrospinal fluid. The patient was treated with penicillin, and had a quick vision improvement. In the case of transplant recipients, clinicians should always consider the diagnosis of ocular syphilis in cases with unexplained visual acuity decrement, as this condition may cause serious complications if not treated.

    Little is known about the specific sexual concerns of kidney transplant (KTx) recipients. The primary objectives of this study were to: (i) describe the importance of sexuality to KTx recipients; (ii) investigate the sexual concerns of KTx recipients; and (iii) examine the relationship between sexual concerns and quality of life (QOL). A secondary objective was to examine potential sexual concern differences by gender, pre-transplant dialysis status, and donor type. This study employed a cross-sectional, descriptive, correlational design. Sexual concerns were identified using the Sexual Concerns Questionnaire, which contains seven subscales. QOL was measured with the SF-8 and the QOL Uniscale. Nearly 73% of subjects rated sexuality as important. Subscales indicating highest area of sexual concerns were communication with healthcare providers about sexuality (Mean (M) = 2.70) and sexual pleasure concerns (M = 2.45). Higher concern ratings regarding health consequences of sexual activity, quality of sexual relationship, sexual pleasure, sexual functioning problems, and pessimistic beliefs about treatment were significantly, inversely related to QOL. Women had significantly higher scores on the Sexual Pleasure and Communication with Healthcare Providers subscales than men. This study reports the sexual concerns of KTx recipients' who are an average of four yr since surgery, and the relationship of these concerns to QOL. © 2014 John Wiley & Sons A/S.

    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.

  1. Viral Infection in Renal Transplant Recipients

    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.

    Full Text Available Introduction: Post-transplant lymphoproliferative syndrome (PTLD is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation. Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation. Ten cases have developed PTLD. Their clinical-pathological characteristics and the treatment received have been analyzed. Results: PTLD incidence was 1.2% (10/851. The mean time from liver transplantation to PTLD diagnosis was 36 months (range 1.2 to 144 months. PTLD localization was extranodal in all cases, the most frequent location being intestinal. Seven cases showed a monomorphic lymphoma which in all cases was differentiated B cell lymphomas. Fifty per cent of the series were seropositive for Epstein-Barr virus. Five patients were alive at the time of the review. Among these patients, we observed three cases of complete remission and two cases of disease stabilization. The death rate was higher in the first year after diagnosis of PTLD. Conclusion: PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. It is essential to identify patients at risk, to establish an early diagnosis and treatment that can change the outcome of the disease.

    To investigate the effect of a supervised upper limb (UL) program (SULP) compared to no supervised UL program (NULP) after lung transplantation (LTx). Randomized controlled trial. Physiotherapy gym. Participants (N=80; mean age, 56±11y; 37 [46%] men) were recruited after LTx. All participants underwent lower limb strength thrice weekly and endurance training. Participants randomized to SULP completed progressive UL strength training program using handheld weights and adjustable pulley equipment. Overall bodily pain was rated on the visual analog scale. Shoulder flexion and abduction muscle strength were measured on a hand held dynamometer. Health related quality of life was measured with Medical Outcomes Study 36-item Short Form health Survey and the Quick Dash. Measurements were made at baseline, 6 weeks, 12 weeks, and 6 months by blinded assessors. After 6 weeks of training, participants in the SULP (n=41) had less overall bodily pain on the visual analog scale than did participants in the NULP (n=36) (mean VAS bodily pain score, 2.1±1.3cm vs 3.8±1.7cm; P<.001) as well as greater UL strength than did participants in the NULP (mean peak force, 8.4±4.0Nm vs 6.7±2.8Nm; P=.037). At 12 weeks, participants in the SULP better quality of life related to bodily pain (76±17 vs 66±26; P=.05), but at 6 months there were no differences between the groups in any outcome measures. No serious adverse events were reported. UL rehabilitation results in short-term improvements in pain and muscle strength after LTx, but no longer-term effects were evident. Crown Copyright © 2017.

    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.

    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. In this article, we discuss these new methods and their potential uses in renal transplant recipients.

    To compare new onset dyslipidaemia in live-related renal transplant recipients taking cyclosporine versus tacrolimus after 3 months of therapy. 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 (3 mg/kg) and group B was treated with tacrolimus (0.1 mg/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 5 ml blood by venipuncture after an overnight fast of 9-12 hours. SPSS 10 was used for statistical analyses. 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 +/- 11.144 kg. 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. 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.

    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.

    Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM). Plasma EBV-miR-BART2-5p was present in higher numbers of IM (7/8) and CHL (7/10) compared to REI (7/12) patients. A trend was observed between the numbers of plasma EBV miRNAs expressed and EBV viral load (p < 0.07). Several EBV-miRs including BART7-3p, 15, 9-3p, 11-3p, 1-3p and 3-3p were detected in IM and CHL patients only. The lytic EBV-miRs, BHRF1-2-3p and 1-1, indicating active viral replication, were detected in IM patients only. One CHL patient developed post-transplant lymphoproliferative disease (PTLD) after several years and analysis of 10 samples over a 30-month period showed an average 24-fold higher change in plasma EBV-miR-BART2-5p compared to the CHL group and 110-fold higher change compared to the REI group. Our results suggest that EBV-miR-BART2-5p, which targets the stress-induced immune ligand MICB to escape recognition and elimination by NK cells, may have a role in sustaining high EBV viral loads in CHL paediatric kidney transplant recipients.

    The aim of this study was to highlight recent evidence on important aspects of influenza vaccination in solid organ transplant recipients. Influenza vaccine is the most evaluated vaccine in transplant recipients. The immunogenicity of the vaccine is suboptimal after transplantation. Newer formulations such as inactivated unadjuvanted high-dose influenza vaccine and the administration of a booster dose within the same season have shown to increase response rates. Intradermal vaccination and adjuvanted vaccines did not show clear benefit over standard influenza vaccines. Recent studies in transplant recipients do not suggest a higher risk for allograft rejection, neither after vaccination with a standard influenza vaccine nor after the administration of nonstandard formulation (high-dose, adjuvanted vaccines), routes (intradermally) or a booster dose. Nevertheless, influenza vaccine coverage in transplant recipients is still unsatisfactory low, potentially due to misinterpretation of risks and benefits. Annual influenza vaccination is well tolerated and is an important part of long-term care of solid organ transplant recipients.

    Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1) expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that most likely hyperfiltration is the key trigger inducing the

    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.

    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.

    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.

    2014-01-01

    Full Text Available Introduction. End stage renal failure in children is a rare but devastating condition, and kidney transplantation remains the only permanent treatment option. The aim of this review was to elucidate the broad surgical issues surrounding the mismatch in size of adult kidney donors to their paediatric recipients. Methods. A comprehensive literature search was undertaken on PubMed, MEDLINE, and Google Scholar for all relevant scientific articles published to date in English language. Manual search of the bibliographies was also performed to supplement the original search. Results. Size-matching kidneys for transplantation into children is not feasible due to limited organ availability from paediatric donors, resulting in prolonged waiting list times. Transplanting a comparatively large adult kidney into a child may lead to potential challenges related to the surgical incision and approach, vessel anastomoses, wound closure, postoperative cardiovascular stability, and age-correlated maturation of the graft. Conclusion. The transplantation of an adult kidney into a size mismatched paediatric recipient significantly reduces waiting times for surgery; however, it presents further challenges in terms of both the surgical procedure and the post-operative management of the patient’s physiological parameters.

    Across pediatric organ transplant populations, patient and family psychosocial functioning is associated with important health-related outcomes. Research has suggested that pediatric heart transplant recipients and their families are at increased risk for adverse psychosocial outcomes; however, recent investigation of psychosocial functioning in this population is lacking. This study aimed to provide a contemporary characterization of psychosocial functioning in pediatric heart transplant recipients and their families. Associations between psychosocial function, demographic variables, and transplant-related variables were investigated. Fifty-six parents/guardians of pediatric heart transplant recipients completed a comprehensive psychosocial screening measure during transplant follow-up clinic visits. Descriptive statistics, correlational analyses, and independent samples t tests were performed. Forty percent of pediatric heart transplant recipients and their families endorsed clinically meaningful levels of total psychosocial risk. One-third of patients presented with clinically significant psychological problems per parent report. Psychosocial risk was unassociated with demographic or transplant-related factors. Despite notable improvements in the survival of pediatric heart transplant recipients over the past decade, patients and families present with sustained psychosocial risks well beyond the immediate post-transplant period, necessitating mental health intervention to mitigate adverse impact on health-related outcomes. © 2018 John Wiley & Sons A/S.

    Sirolimus is an immunosuppressive agent increasingly used in cardiac transplant recipients in the setting of allograft vasculopathy or worsening renal function. Recently, sirolimus has been associated with increased risk of venous thromboembolism (VTE) in lung transplant recipients. To investigate whether this association is also present in cardiac transplant recipients, we retrospectively reviewed the charts of 67 cardiac transplant recipients whose immunosuppressive regimen included sirolimus and 134 matched cardiac transplant recipients whose regimen did not include sirolimus. Rates of VTE were compared. Multivariable Cox proportional hazards models tested the association of sirolimus use with VTE. A higher incidence of VTE was seen in patients treated with vs. without sirolimus (8/67 [12%] vs. 9/134 [7%], log-rank statistic: 4.66, p=0.03). Lower body mass index (BMI) and total cholesterol levels were also associated with VTE (p<0.05). The association of sirolimus with VTE persisted when adjusting for BMI (hazard ratio [95% confidence interval]: 2.96 [1.13, 7.75], p=0.03) but not when adjusting for total cholesterol (p=0.08). These data suggest that sirolimus is associated with an increased risk of VTE in cardiac transplant recipients, a risk possibly mediated through comorbid conditions. Larger, more conclusive studies are needed. Until such studies are completed, a heightened level of awareness for VTE in cardiac transplant recipients treated with sirolimus appears warranted. © 2012 John Wiley & Sons A/S.

    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.

    2011-11-01

    Survival after solid organ transplantation has increased in the era of tacrolimus and mycophenolate. This increased survival could be due in part to the broad clinical use of these potent and specific agents for maintenance immunosuppression. These drugs have enhanced specificity and potency for T and B lymphocytes compared with their predecessors, cyclosporine and azathioprine. Between 2008 and 2010, the United States Food and Drug Administration approved several generic formulations of both tacrolimus and mycophenolate mofetil. Deciding whether generic products can be safely substituted for the innovator product is a clinical dilemma similar to that which occurred when generic formulations of cyclosporine became available. We describe the concerns regarding generic immunosuppression use, summarize expert opinion and consensus statements in transplantation, analyze the potential impact of generic substitution, and provide estimates of populations affected based on generic drug market penetration. Formulary considerations such as cost, availability, and potential drug ordering and drug selection errors are described, and transplant coordinator and patient perspectives are reviewed. Finally, general recommendations about the use of generic maintenance immunosuppression in solid organ transplant recipients are provided. Although more research is needed to confirm clinical and therapeutic equivalence and pharmacoeconomic benefit, generic immunosuppressants can be safely substituted for innovator products as long as patients consistently receive the same product, patients and clinicians are aware of when substitutions occur, and enhanced therapeutic drug monitoring is provided during the transition.

    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.

    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.

    Asymptomatic bacteriuria, defined as bacteriuria without signs or symptoms of urinary tract infection (UTI), occurs in 17% to 51% of kidney transplant recipients and is thought to increase the risk for a subsequent UTI. No consensus exists on the role of antibiotics for asymptomatic bacteriuria in kidney transplantation. To assess the benefits and harms of treating asymptomatic bacteriuria in kidney transplant recipients with antimicrobial agents to prevent symptomatic UTI, all-cause mortality and the indirect effects of UTI (acute rejection, graft loss, worsening of graft function). We searched the Cochrane Kidney and Transplant Register of Studies up to 1 September 2017 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov. All randomised controlled trials (RCTs) and quasi-RCTs in any language assessing treatment of asymptomatic bacteriuria in kidney transplant recipients at any time-point after transplantation. Two authors independently determined study eligibility, assessed quality and extracted data. Primary outcomes were incidence of symptomatic UTI and incidence of antimicrobial resistance. Other outcomes included incidences of all-cause mortality, graft loss, graft rejection, graft function, hospitalisation for UTI, adverse reactions to antimicrobial agents and relapse or persistence of asymptomatic bacteriuria. We expressed dichotomous outcomes as absolute risk difference (RD) or risk ratio (RR) with 95% confidence intervals (CI) and continuous data as mean differences (MD) with 95% CI. Data were pooled using the random effects model. We included two studies (212 participants) comparing antibiotics versus no treatment, and identified three on-going studies. Overall, incidence of symptomatic UTI varied between 19% and 31

    The purpose of this study was to examine the sleep quality and health-related quality of life (HRQOL) in patients after renal transplantation and to explore the relationship between the quality of sleep and the HRQOL. Sleep disorders are still an important clinical problem after renal transplantation. Previous studies mainly focused on patients' sleep quality before kidney transplant. More studies are needed to document sleep quality after renal transplantation. A cross-sectional design was used in this study. A convenience sample of renal transplant recipients was recruited at an outpatient transplant clinic of a general hospital in Beijing, China. The Pittsburgh Sleep Quality Index (PSQI) was used to measure quality of sleep. The Medical Outcomes Study 36-item Short Form (MOS SF-36) was used to measure health-related quality of life. The average PSQI score of the 204 renal transplant recipients was 5.81±3.52, significantly lower than the norm. Fifty (24.5%) recipients were classified as having poor sleep quality (global PSQI > 7). The mean scores of renal transplant recipients for SF-36 Mental Component Summary (MCS) and Physical Component Summary (PCS) were 47.57±6.71 and 48.26±9.66 respectively. Compared with residents in Sichuan province, recipients' scores for SF-36 dimensions were statistically lower except the dimension of mental health. SF-36 scores of poor sleepers (PSQI > 7) were significantly lower than the good sleepers (PSQI ≤ 7) in both the MCS and PCS. Significant differences exist between the groups in physical function, bodily pain, vitality, and mental health dimensions. Sleep quality and HRQOL of patients after renal transplantation were lower than the norm. Poor sleep is associated with lower HRQOL. Health professionals need to pay attention to sleep quality and HRQOL in renal transplant recipients and take appropriate measures to improve patients' sleep quality and HRQOL.

    Full Text Available Immunosuppressed renal transplant recipients seem to be at significantly increased risk of developing neoplasms comparatively to nonimmunosuppressed individuals. A history of malignancy exposes the patient to a high risk for relapse after transplantation. We present a trans-plant recipient with a history of an ovarian mixed germ-cell tumor, with choriocarcinoma com-ponent, which was treated seven years prior to transplantation. After three years of follow-up, there was no evidence of tumor relapse. To our knowledge, there is no report of such case in the English literature. Regarding our case report and patients with a history of ovarian germ-cell neoplasm, waiting time before transplantation must take into consideration the stage of the tumor, its prognosis, the proportion of different tumor components, and the overall prognosis of the patient if transplantation is withheld.

    In order to evaluate glucose tolerance following renal transplantation, intravenous glucose tolerance tests (IVGTT), with evaluation of hormonal responses to the intravenous glucose load and percent specific 125 I-insulin binding to peripheral blood monocytes, were studied in eight clinically stable kidney transplant recipients. For comparison purposes, identical studies were done in eight control subjects and seven clinically stable hemodialysis patients. One transplant recipient was glucose intolerant, with fasting hyperglycemia, elevated HbA1C, and abnormal glucose decay constant. Impaired pancreatic insulin release appeared to be the major factor accounting for his glucose intolerance. The seven glucose-tolerant transplant recipients had significantly increased insulin release during IVGTT compared to control subjects, and significant correlations were found among insulin release, glucose decay constant, and fasting blood sugar in those patients. Insulin binding to monocytes was significantly greater in transplant recipients than control subjects due to an increase in insulin binding capacity per cell. A significant correlation was found between percent specific 125 I-insulin binding and steroid dose, expressed as mg/kg body weight/day, in those patients. Thus, chronic steroid administration does not cause glucose intolerance in transplant recipients who manifest steroid-associated increases in pancreatic insulin release and cellular insulin binding capacity

    Full Text Available Objective. Evaluate the prevalence and outcomes of urinary tract infection (UTI among renal transplant recipients. Methods. A secondary analysis of the Nationwide Inpatient Sample 2009–2011 was conducted. Survey-weighted multivariable regression analyses were used to examine the impact of UTI on transplant complications, total charges, and length of stay. Results. A total of 1,044 renal transplant recipients, representing a population estimate of 49,862, were included in the study. UTI was most common in transplant recipients with hypertension (53% and prevalence was noted to be 28.2 and 65.9 cases per 1,000 for men and women, respectively. UTI increased the likelihood of transplant complications (182% for men, 169% for women. Total charges were 28% higher among men as compared to 22% among women with UTI. Such infection also increased the length of stay by 87% among men and 74% among women. Discussion. UTI in renal transplant recipients was associated with prolonged length of stay, total charges, and increased odds of transplant complications. Interventions to prevent UTI among such patients should be a priority area for future research and practice.

    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.

  6. Parvovirus-B19-associated complications in renal transplant recipients.

    2007-10-01

    Parvovirus B19 is a common human pathogen, causing erythema infectiosum in children, hydrops fetalis in pregnant women, and transient aplastic crisis in patients with chronic hemolytic anemia. Immunosuppressed patients can fail to mount an effective immune response to B19, resulting in prolonged or persistent viremia. Renal transplant recipients can develop symptomatic B19 infections as a result of primary infection acquired via the usual respiratory route or via the transplanted organ, or because of reactivation of latent or persistent viral infection. The most common manifestations of B19 infection in immunosuppressed patients are pure red cell aplasia and other cytopenias. Thus, this diagnosis should be considered in transplant recipients with unexplained anemia and reticulocytopenia or pancytopenia. Collapsing glomerulopathy and thrombotic microangiopathy have been reported in association with B19 infection in renal transplant recipients, but a causal relationship has not been definitively established. Prompt diagnosis of B19 infection in the renal transplant recipient requires a high index of suspicion and careful selection of diagnostic tests, which include serologies and polymerase chain reaction. Most patients benefit from intravenous immunoglobulin therapy and/or alteration or reduction of immunosuppressive therapy. Conservative therapy might be sufficient in some cases.

    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.

    Full Text Available Cystitis cystica or glandularis is a clinical and pathological entity of the bladder mucosa occurring secondary to inflammation or chronic obstruction. Its premalignant nature remains controversial, especially in an immunocompromised transplant recipient. We present a rare case where a chronic kidney disease patient was found to have cystitis glandularis while being worked up for living-related donor renal transplant and describe its subsequent management.

    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.

    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.

    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. Results: The parasites that were detected included Cryptosporidium species (21%, 8/38, Cystoisospora (Isospora belli (8%, 3, Cyclospora cayetanensis (5%, 2, G. lamblia (11%, 4, Hymenolepis nana (11%, 4, Strongyloides stercoralis (3%, 1 and Blastocystis hominis (3%, 1. Multilocus genotyping of Cryptosporidium species at SSUrRNA, COWP and DHFR loci could detect four isolates of C. hominis; two of C. parvum, one of mixed genotype and one could not be genotyped. All the C. hominis isolates were detected in adult post

    Liver transplantation has become the treatment of choice for patients with end-stage liver disease. Most studies show a positive effect on quality of life after liver transplantation, but most studies are based on data from Western countries and little is known about quality of life in liver transplant recipients in Turkey or other developing countries. To investigate liver transplant recipients' quality of life and factors affecting it, before and 3 months after transplantation in western Turkey. Descriptive and comparative, with data collected prospectively. Two medical centers in Western Turkey. Sixty-five adult recipients of a liver transplant between May 15 and December 31,2007. Quality of life was measured by using the Nottingham Health Profile Turkish version, and sociodemographic and clinical data were collected from patients' records. Scores on all subscales of the Nottingham Health Profile differed significantly from before to after liver transplantation. The differences between the mean scores for quality of life before and after transplantation varied significantly with the patients' sex and disease severity.

    Sensitization of potential renal transplant recipients may impact the selection of donors and the outcome of transplant. Another element of the potential kidney transplant recipient immune system that provides useful information regarding the transplant outcome is the immunologic CD30 molecule. This study shows a significant correlation between the pre-transplant high level of soluble CD30 and increased incidence of post-transplant infection. Only 7/34 (20.6%) of the patients who had a low level of sCD30 ( 90 U/mL) of sCD30 (p sCD30 pre-transplant was also correlated with the increased level of serum creatinine (p transplant malignancy (p sCD30 was also noted among females (74%), as compared with males (50%) with p antigen (HLA) mismatches on rejection was seen. These results show that higher pre-transplant immunologic reactivity measured by sCD30 level was associated with post-transplant outcome. The high level of sCD30 among females may indicate an active immunologic status, perhaps because of previous pregnancies.

    Full Text Available The adipokine progranulin has metabolic proprieties, playing a role in obesity and insulin resistance. Its levels seems to be dependent of renal function, since higher progranulin concentration is observed in patients with end-stage kidney disease. However, the effect of kidney transplantation on progranulin remains unknown.To assess the serum progranulin levels in kidney transplant recipients before and after kidney transplantation.Forty-six prospective kidney transplant recipients were included in this longitudinal study. They were evaluated before transplantation and at three and twelve months after transplantation. Clinical, anthropometric and laboratorial measurements were assessed. Progranulin was determined with enzyme-linked immunosorbent assays.Serum progranulin significantly decreased in the early period after transplantation (from 72.78 ± 2.86 ng/mL before transplantation to 40.65 ± 1.49 ng/mL at three months; p<0.01 and increased at one year (53.15 ± 2.55 ng/mL; p<0.01 vs. three months, remaining significantly lower than before transplantation (p<0.01 (pover time<0.01. At one year after transplantation, there was a significant increase in body mass index, trunk fat and waist circumference compared to immediate period after transplantation. Progranulin was associated with waist circumference and fasting plasma glucose after adjusted for age, gender, study period, glomerular filtration rate, interleukin-6, high sensitivity C reactive protein and adiponectin.Progranulin serum levels are increased before transplantation and a reduction is observed in the early period after transplantation, possibly attributed to an improvement in renal function. At one year after transplantation, an increment in progranulin is observed, seems to be independent of glomerular filtration, and remained significantly lower than before transplantation.

    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.

    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 allograft recipient who presented with relapsing bacterial UTI complicated by systemic fungemia; also, a brief review of fungal UTI is attempted. (author)

    Anemia, iron deficiency anemia (IDA), and iron deficiency (ID) are highly prevalent in renal transplant recipients (RTR). Anemia is associated with poor outcome, but the role of ID is unknown. Therefore, we aimed to investigate the association of ID, irrespective of anemia, with all-cause mortality

    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.

    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.

    Dual kidney transplantation (DKT) is a largely accepted strategy to enlarge the donor pool. Niguarda Hospital started this program in December 2010, and 38 DKT have been performed. In our series, we included recipients older than those in the other series published in literature. The aim of this study was to know if our recipient selection criteria for DKT are safe. We reviewed our data base of DKT and analyzed recipients' medical history, surgical technique, post-operative complications, graft survival, morbidity, and mortality. We then compared our results with the literature. From December 2010 to April 2015, 38 DKT were performed in Niguarda Hospital. Delayed graft function was present in 21 recipients. Explantation of both kidneys was performed in 1 patient and explantation of 1 kidney in 6 patients. Post-operative complications were present in 8 patients. Five patients returned to hemodialysis after DKT. One recipient died of medical post-operative sepsis. The mean follow-up was 24 months. Graft survival and patient survival were 86.84% and 97.93%, respectively. Compared with the literature, our series had similar mortality and morbidity rates, even if recipients' age was higher than in other series. The strategy of DKT allocation in elderly recipients is safe. Further studies have to be performed to optimized selection of the recipients for DKT not to disadvantage younger patients in the transplant waiting list and to improve the technique of organ evaluation and preservation to refine graft allocation.

    Fourteen patients with aplastic anemia and one with the Wiskott-Aldrich syndrome who were specifically sensitized against their donors were successfully engrafted with bone marrow from those donors. Sensitivity was detected in antibody-independent and antibody-dependent cell-mediated lysis assays. In order to erase this immunity to non-MHR familial transplantation antigens, multiagent immunosuppression with cyclophosphamide, procarbazine, and whole rabbit antithymocyte serum (ATS) was used. The data suggest that ATS was largely responsible for abrogation of this sensitivity and indicate that immunity does not represent a barrier to successful transplantation

    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.

  10. MONITORING OF CMV INFECTION IN KIDNEY TRANSPLANT RECIPIENTS

    Full Text Available Human cytomegalovirus is a ubiquitous herpesvirus that establishes lifelong latency after primary infection, but can cause life-threatening disease in immunosuppressed patients. CMV invasive disease leads to significant morbidity and mortality following kidney transplantation. We tested 2 groups of patients - Group A included 20 potential kidney recipients and 29 potential donors investigated by ELISA and Group B included 53 adult kidney transplant recipients all of them tested in ELISA and 24 of them tested in QRT-PCR for CMV-DNA from plasma samples. In group A 16 (80% of 20 potential kidney recipients were anti-CMV IgG positive and 4 (20% were anti-CMV IgG negative. Twenty eight of 29 potential donors were found seropositive, and only one was not infected. In group B overall 119 ELISA tests for specific anti-CMV antibodies were performed. Anti-CMV IgM negative was 68 (57% of the tested samples, twelve (10% showed anti-CMV IgM equivocal results and 39 samples (33% were with anti-CMV IgM positive. Seven of them (13,2% showed repeatedly anti CMV IgM positive results. All 119 (100% displayed аnti-CMV IgG positive results. Overall 41 PCR analyses from plasma samples of 24 kidney transplant recipients (group B were performed. CMV-DNA replication was detected in 5 plasma samples obtained from 3 patients (12.5% at a different time - from 20 days till almost 8 years after the transplantation. Despite the high seroprevalence to CMV 20% of the potential recipients were at high risk of primary infection when receiving a kidney from a seropositive donor. Positive serological results during the regular post-transplantation monitoring complemented with or without clinical data are indicative and require further QRT-PCR analysis.

    Antithymocyte antibody (ATA) remains the most commonly used induction immunosuppressive agent in renal transplantation (RT). To date, few case reports of ATA-induced coagulopathy exist. We performed a single-center, retrospective analysis of renal transplant recipients (RTRs) who underwent RT followed by ATA therapy between 2007 and 2011. The protocol used for deceased donor and unrelated living donor recipient immunosuppression was Thymoglobulin (TMG), methylprednisolone, Cellcept, Prograf, and Rapamune. In related living donor recipients, Simulect (SIM) was substituted for TMG. The international normalized ratio (INR) was routinely checked on days 0 and 2, and thereafter at the discretion of the surgeon. RTRs were transfused packed red blood cells (PRBCs) or fresh frozen plasma (FFP) at the discretion of the surgeon. During the study period, 257 RTs were performed at our institution. The following 18 RTR were excluded: simultaneous kidney and pancreas transplant recipients (4), RTRs on warfarin at the time of admission (2), RTRs who received OKT3 (2), and RTRs with INR ≥ 1.2 at the time of admission (10). Of the remaining 239 RTR, 208 (87%) underwent TMG induction therapy; 31 RTR (13%) underwent SIM induction therapy. The mean INR peaked in both groups on day 4 but was higher in TMG recipients (TMG 1.35, SIM 1.20). FFP was transfused in 65 TMG (31%) and 3 SIM (10%) recipients (P = .01); PRBCs were transfused in 88 TMG (44%) and 6 SIM (19%) recipients (P = .02). No patients returned to the operating room for bleeding complications within 7 days of RT. Patient age, gender, ethnicity, and diabetes status were not statistically significant factors in the development of coagulopathy. TMG administration is associated with coagulopathy. Using an INR screening protocol and an aggressive transfusion protocol, bleeding complications associated with coagulopathy can be avoided in this higher-risk group. Copyright © 2013 Elsevier Inc.

    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.

    Kidney transplantation is the optimal treatment for children with end-stage renal disease. For children with undocumented immigration status, access to kidney transplantation is limited, and data on transplant outcomes in this population are scarce. The goal of the present retrospective single-center study was to compare outcomes after kidney transplantation in undocumented children with those of US citizen children. Undocumented residency status was identified in 48 (17%) of 289 children who received a kidney transplant between 1998 and 2010. In undocumented recipients, graft survival at 1 and 5 years posttransplantation was similar, and mean estimated glomerular filtration rate at 1 year was higher than that in recipients who were citizens. The risk of allograft failure was lower in undocumented recipients relative to that in citizens at 5 years posttransplantation, after adjustment for patient age, donor age, donor type, and HLA mismatch (p immigration policies for the undocumented that facilitate access to work-permits and employment-related insurance for this disadvantaged group. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    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.

    Allogeneic and autologous bone marrow transplantation (BMT) have been associated with nutritionally-depleting side effects. Total parental nutrition (TPN) has become the standard, but it has not been demonstrated that TPN is the appropriate method of nutritional support. Therefore, in a prospective, randomized clinical trial TPN and enteral feeding were compared for their effectiveness in maintaining the nutritional status of patients through the first 29 post-transplant days. Nutritional assessment included measurement of serum proteins, body weight, anthropometry and isotope dilution analysis of body composition. Total body water (TBW) and extracellular fluid (ECF) were quantified by standard radioisotope dilution techniques using tritiated water and 169 ytterbium-diethylenetriaminepentaacetate, respectively as the tracers. Consenting patients 10-58 years of age were stratified by type of BMT (autologous or allogeneic) and randomized to either TPN plus ad libitum oral feeding or the individualized enteral feeding program (EFP), which included one-on-one counseling, meal-by-meal menu selection, special snacks and tube feeding. There were no differences in the rate of hematologic recovery, incidence of graft-versus-host disease, organ toxicity, length of hospitalization or survival. Therefore, the observed changes in body composition were not clinically significant. Even allowing for increased dietary service, the EFP was only half as expensive as TPN. It was concluded that TPN is not superior to the EFP and therefore, TPN should be reserved for patients who demonstrate intolerance to enteral feeding

    Bisphosphonates may prevent or treat the bone loss promoted by the immunosuppressive regimens used in renal transplantation. Risedronate is a commonly used third-generation amino-bisphosphonate, but little is known about its effects on the bone health of renal transplant recipients. We randomly assigned 42 new living-donor kidney recipients to either 35 mg of risedronate weekly or placebo for 12 months. We obtained bone biopsies at the time of renal transplant and after 12 months of protocol treatment. Treatment with risedronate did not affect bone mineral density (BMD) in the overall cohort. In subgroup analyses, it tended to preserve BMD in female participants but did not significantly affect the BMD of male participants. Risedronate did associate with increased osteoid volume and trabecular thickness in male participants, however. There was no evidence for the development of adynamic bone disease. In summary, further study is needed before the use of prophylactic bisphosphonates to attenuate bone loss can be recommended in renal transplant recipients.

    Recent evidence suggests that fibromyalgia syndrome (FS) is associated with inflammation and endothelial dysfunction. Our aim was to determine the prevalence of FS in renal transplant recipients and to identify possible links between FS and clinical and laboratory parameters. Ninety-nine kidney transplant recipients with normal graft functions (37.15 ± 10.83 years old, 67 male) were enrolled in the study. All subjects completed the Fibromyalgia Impact Questionnaire (FIQ). The biochemical and clinical parameters in the 1st post-transplantation year were retrospectively recorded. Cardiovascular parameters, including body composition analyses (Tanita), ambulatory blood pressure monitoring data, and pulse-wave velocity, were cross-sectionally analyzed. Mean FIQ score for the whole group was 21.4 ± 14.7. Eight patients had FIQ score >50, and these patients had significantly higher left ventricular mass index than patients with lower FIQ score (P = .048). Patients were divided according to their physical impairment score (PIS): PIS ≥5 (n = 50) and PIS FIQ (7.6% vs 9.4%; P = .0001) than in other patients. FS in renal transplant recipients was strongly associated with hypertension, arterial stiffness, obesity, and renal allograft dysfunction. Copyright © 2015 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

    Since lung transplant recipients are susceptible to infections and inhaled pollution, many centers warn against pets. However, data supporting this recommendation are lacking. Our program is less restrictive regarding pets. This study, for the first time, investigates the association of pets with physiological and psychological parameters in these patients. A questionnaire concerning pets was sent to 104 lung transplant recipients. Lung function tests, levels of exhaled nitric oxide (FE(NO)), need for antibiotic treatments and hospitalizations, creatinine clearance, body mass index (BMI) and demographic data were assessed. Additionally, the questionnaire of life satisfaction (FLZ), a question on summarized life satisfaction (LS), the life orientation test (LOT), the hospital anxiety depression scale (HADS) and the social support questionnaire (F-SozU) were assessed. Response rate was 86%. Fifty-two percent defined themselves as pet owners, whereas 48% did not. The two groups did not differ in demographic or physiological data. Significant differences in FLZ (79/65, p = 0.04), in LS (4.3/3.9, p = 0.01), LOT (32/29, p = 0.006) and F-SozU (4.5/4.2, p = 0.04) were found in favor of pet owners. In lung transplant recipients keeping pets the frequency of somatic complications is not higher compared to lung transplant recipients without pets. After lung transplantation, pets are associated with a better quality of life.

    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

    BACKGROUND The effect of everolimus, one of the mammalian targets of rapamycin inhibitors, on cardiac function was evaluated in kidney transplant recipients. MATERIAL AND METHODS Seventy-six participants who underwent kidney transplant between March 2009 and May 2016 were retrospectively reviewed. To standardize everolimus administration, the following criteria were used: (1) the recipient did not have a donor-specific antigen before kidney transplantation; (2) the recipient did not have proteinuria and uncontrollable hyperlipidemia after kidney transplantation; and (3) acute rejection was not observed on protocol biopsy 3 months after kidney transplantation. According to these criteria, everolimus administration for maintenance immunosuppression after kidney transplantation was included. Cardiac function was compared between the treatment group (n=30) and non-treatment group (n=46). RESULTS The mean observation periods of the treatment and non-treatment groups were 41.3±12.6 and 43.9±19.8 months, respectively (p=0.573). The mean ejection fraction and fractional shortening of the treatment and non-treatment groups after kidney transplant were 66.5±7.9% vs. 69.6±5.5% (p=0.024) and 37.1±6.2% vs. 39.3±4.7% (p=0.045), respectively. In the treatment group, the mean ejection fraction and fractional shortening before and after kidney transplantation did not differ significantly (p=0.604 and 0.606, respectively). In the non-treatment group, the mean ejection fraction and fractional shortening before and after kidney transplantation differed significantly (p=0.004 and 0.006, respectively). CONCLUSIONS Supplementary administration of everolimus after kidney transplantation can reduce cardiac systolic function.

    For dialysis patients with a cancer history, a period of surveillance is generally recommended before listing for transplantation. However, the outcomes of patients with cancer recurrence and/or a second primary cancer after transplantation are unknown. To determine the prognosis of kidney transplant recipients who developed cancer after transplantation and whether this varied with cancer types (first cancer, recurrence, second primary cancer). Using data from the Australian and New Zealand Dialysis and Transplant Registry, we compared the cancer-specific and all-cause mortality among recipients with different cancer types using adjusted Cox proportional hazard models. Of the 21,415 recipients transplanted between 1965 and 2012, 3% (651 of 21,415) had a previous cancer history. A total of 2840 (13%) recipients developed cancer after the first transplant, of whom 2760 (97.2%) developed a first cancer, 23 (0.8%) experienced cancer recurrence, and 57 (2%) developed a second primary cancer. There were no significant differences in the risks of cancer-specific and all-cause mortality between recipients who developed their first cancer after transplant, those with cancer recurrence (adjusted hazard ratios [aHRs], 0.79; 95% confidence interval [95% CI], 0.38-1.67; P = 0.54 and aHRs, 0.86; 95% CI, 0.45-1.66; P = 0.66, respectively) and recipients who developed a second primary cancer after transplantation (aHRs, 1.01; 95%CI, 0.63-1.62; P = 0.95 and aHRs, 1.16; 95% CI, 0.79-1.69; P = 0.45, respectively). Among patients with a previous history of malignancy, recurrent and second primary cancers are infrequent after renal transplantation. A history of previous malignancy does not have an additive effect on the cancer-specific and overall survival of kidney transplant recipients who develop cancer.

    The benefits of kidney transplantation in diabetic patients with peripheral vascular disease (PVD) are unclear. While patients may have improved survival compared to dialysis, the burden of care after transplant has not been assessed. We performed a retrospective review of adult diabetic kidney-only transplant recipients with and without PVD transplanted from January 2012 until June 30, 2015. Of 203 diabetic kidney transplant recipients, 56 (27.6%) had PVD and 147 (72.4%) had no PVD. At a median of 3.14 years follow up there were no significant differences in 30-, 90-, or 1-year readmission rates. At 1 year after transplant, PVD patients were significantly more likely to have a greater sum of unplanned inpatient days (44.6% versus 27.9% with ≥10 inpatient days, p=0.03) and at least one reoperation (28.6% vs. 8.7%, pPVD had significantly increased rates of non-graft related operations of which 31.2% were PVD related. Diabetic patients with PVD utilize more resources after kidney transplant, spending more time in the hospital and undergoing more post-transplant operations. The causes of readmission are predominantly related to progression of PVD rather than allograft complications. This article is protected by copyright. All rights reserved.

    Oral health and dental maintenance have become part of the standard of care for pediatric liver transplant recipients. These individuals tend to suffer particularly from dental problems, such as gingival enlargement, gingivitis, poor oral hygiene, dental hypoplasia, and caries. Saliva composition influences oral hygiene and disease states. We investigated saliva composition and its association with the oral health of young recipients of liver transplants. In 70 patients, 36 liver transplant recipients (ages 2-23 years) and 34 healthy controls (ages 4-21 years), we measured the following variables: (a) oral hygiene, (b) gingival inflammation, (c) caries status, (d) dental calculus formation, (e) oral mucosal pH, and (f) salivary protein composition. Lower mean decayed, missing, and filled teeth index (P=0.0038), higher mean gingival index (P=0.0001), and higher mean calculus score (P=0.003) were found in the transplanted study group compared with the control. The mean mucosal pH for seven intraoral sites was higher in the transplant group (P=0.0006). The median salivary albumin concentration was significantly lower in the transplant group (P=0.01), as was the median salivary albumin/total protein ratio (P=0.0002). In post-liver transplant pediatric recipients, low incidence of caries, together with high incidence of dental calculus, could be attributed to elevated oral mucosal pH. Salivary albumin and immunoglobulin A levels were relatively low in these patients. Clinicians should pay particular attention to the oral health and dental care of liver transplanted children.

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

    Full Text Available Scrub typhus is a rickettsial infection commonly seen in Asia. The clinical presentation ranges from nonspecific febrile illness to potentially fatal multiorgan involvement such as liver, kidney, or lung. Central nervous system involvement is uncommon. We report a 45-year-old female renal transplant recipient who presented with fever, headache, meningeal signs, graft dysfunction, and eschar. IgM antibodies against Orientia tsutsugamushi were positive by enzyme-linked immunosorbent assay. Despite oral doxycycline therapy for 5 days, she did not improve but responded well to intravenous azithromycin. To the best of our knowledge, scrub typhus as a cause of meningitis in a renal transplant recipient has not been reported so far.

    A recent randomized trial demonstrated that 1 year of antiviral prophylaxis for cytomegalovirus (CMV) after lung transplantation is superior to 3 months of treatment for prevention of CMV disease. However, it is uncertain if a shorter duration of prophylaxis might result in a similar rate of CMV disease among select lung transplant (LT) recipients who are at lower risk for CMV disease, based on baseline donor (D) and recipient (R) CMV serologies. We retrospectively assessed incidence, cumulative probability, and predictors of CMV disease and viremia in LT recipients transplanted between July 2004 and December 2009 at our center, where antiviral CMV prophylaxis for 6-12 months is standard. Of 129 LT recipients, 94 were at risk for CMV infection based on donor CMV seropositivity (D+) or recipient seropositivity (R+); 14 developed CMV disease (14.9%): 11 with CMV syndrome, 2 with pneumonitis, and 1 with gastrointestinal disease by the end of follow-up (October 2010); 17 developed asymptomatic CMV viremia (18.1%). The cumulative probability of CMV disease was 17.4% 18 months after transplantation. CMV D+/R- recipients who routinely received 1 year of prophylaxis were more likely to develop CMV disease compared with D+/R+ or D-/R+ recipients, who routinely received 6 months of prophylaxis (12/45 vs. 2/25 vs. 0/24, P = 0.005). Recipients who stopped CMV prophylaxis before 12 months (in D+/R- recipients) and 6 months (in R+ recipients) tended to develop CMV disease more than those who did not (9/39 vs. 3/41, P = 0.06). On a 6-month CMV prophylaxis protocol, few R+ recipients developed CMV disease in this cohort. In contrast, despite a 12-month prophylaxis protocol, D+/R- LT recipients remained at highest risk for CMV disease. © 2012 John Wiley & Sons A/S.

    Full Text Available Data regarding the socioeconomic status in Iranian kidney transplant (KT recipients is lacking. 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.

  14. Critical care of the hematopoietic stem cell transplant recipient.

    An estimated 50,000 to 60,000 patients undergo hematopoietic stem cell transplantation (HSCT) worldwide annually, of which 15.7% are admitted to the intensive care unit (ICU). The most common reason for ICU admission is respiratory failure and almost all develop single or multiorgan failure. Most HSCT recipients admitted to ICU receive invasive mechanical ventilation (MV). The overall short-term mortality rate of HSCT recipients admitted to ICU is 65%, and 86.4% for those receiving MV. Patient outcome has improved over time. Poor prognostic indicators include advanced age, poor functional status, active disease at transplant, allogeneic transplant, the severity of acute illness, and the development of multiorgan failure. ICU resource limitations often lead to triage decisions for admission. For HSCT recipients, the authors recommend (1) ICU admission for full support during their pre-engraftment period and when there is no evidence of disease recurrence; (2) no ICU admission for patients who refuse it and those who are bedridden with disease recurrence and without treatment options except palliation; (3) a trial ICU admission for patients with unknown status of disease recurrence with available treatment options.

    Increased cold ischemia time in cadaveric kidney transplants has been associated with a high rate of delayed graft function (DGF), and even with graft survival. Kidney transplantation using in-house donors reduces cold preservation time. The purpose of this study was to compare the clinical outcomes after transplantation in house and externally. We retrospectively reviewed the medical records of donors and recipients of 135 deceased-donor kidney transplantations performed in our center from March 2009 to March 2016. Among the 135 deceased donors, 88 (65.2%) received the kidneys from in-house donors. Median cold ischemia time of transplantation from in-house donors was shorter than for imported donors (180.00 vs 300.00 min; P house donors. Imported kidney was independently associated with greater odds of DGF in multivariate regression analysis (odds ratio, 4.165; P = .038). However, the renal function of recipients at 1, 3, 5, and 7 years after transplantation was not significantly different between the 2 groups. Transplantation with in-house donor kidneys was significantly associated with a decreased incidence of DGF, but long-term graft function and survival were similar compared with imported donor kidneys.

    The pre-transplant serum level of soluble CD30 (sCD30), a proteolytic derivative of the lymphocyte surface receptor CD30, has been suggested as a biomarker for immunologic risk after organ transplantation. Pre-transplant serum sCD30 levels were determined in 200 consecutive adult heart transplant recipients undertaken at a single center. Transplant outcome (acute rejection in the first 12 months and patient survival up to 5 years post-transplant) was determined. Patients treated with a left ventricular assist device (LVAD) prior to transplantation (n = 28) had higher levels of sCD30 (median 64 U/ml, range 12 to 112 U/ml) than those (n = 172) with no LVAD (median 36 U/ml, range 1 to 158 U/ml, p sCD30 levels were "low" (lower quartile, 58 U/ml, n = 50). Neither acute rejection nor recipient survival differed according to sCD30 level, with values (mean +/- SEM) of 0.30 +/- 0.04, 0.23 +/- 0.03 and 0.30 +/- 0.05 acute rejection episodes per 100 days in the low, intermediate and high groups, respectively, with recipient survival rates at 1 year of 77.7%, 84.9% and 86% and at 5 years of 73.6%, 67.9% and 75.8%, respectively. Pre-transplant serum sCD30 level does not predict acute allograft rejection or recipient survival after heart transplantation, although sCD30 levels are increased by LVAD, possibly as a result of biomaterial-host immune interaction.

    Dyslipidemia is common in liver transplant recipients. This retrospective study investigates whether donors play a role. Prospectively collected data of donors and recipients of deceased-donor liver transplantation (DDLT) and living-donor liver transplantation (LDLT) were reviewed. Total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein (HDL) and fasting glucose were compared between groups. HDL ≥1.6 mmol/L at 2 years after transplant was considered the marker of a favorable post-transplant lipid profile in recipients. Univariate and multivariate analyses were performed to identify predictive factors for this marker. There were 85 DDLTs and 80 LDLTs. LDLT donors were younger (30 vs. 50 years, p index (21.2 vs. 23.7, p glucose (4.85 vs. 7.21 mmol/L, p triglyceride (0.87 vs. 1.22 mmol/L, p = 0.016) but higher HDL (1.58 vs. 1.39 mmol/L, p = 0.022). LDLT recipients also had higher HDL at 1 year (1.48 vs. 1.28 mmol/L, p = 0.026) and 2 years (1.43 vs. 1.21 mmol/L, p = 0.008). Fourteen (16.5%) DDLT recipients and 27 (33.8%) LDLT recipients had HDL ≥1.6 mmol/L at 2 years. On multivariate analysis, donor HDL ≥1.6 mmol/L (RR 4.311, 95% CI 1.666-11.158, p = 0.003) and recipient body mass index <24 (RR 2.753, 95% CI 1.064-7.127, p = 0.037) were the two independent predictive factors. LDLT recipients had better lipid profiles than DDLT recipients. The feature of high HDL level in donors was transferred to recipients.

Therefore, the validity of disease-specific instruments to measure HQoL in renal transplant recipients, such as the Kidney Transplant Questionnaire (KTQ, needs further investigation. The objective of this study was to assess the concurrent validity of the KTQ in adult US renal transplant recipients using the well established SF-12 Health Survey version 2 (SF-12v2 as the comparison instrument. Methods: One hundred and fourteen renal transplant recipients met the following inclusion criteria for this study, ie, were at least 21 years of age, more than two years post-transplant, and receiving immunosuppressant therapy. Subjects were asked to complete a series of HQoL instruments, ie, the KTQ and the SF-12v2 (physical component summary [PCS-12] and mental component summary [MCS-12]. Descriptive statistics were calculated, and correlational analyses were conducted to examine the concurrent validity of the HQoL instruments. Results: Among 100 participants (87.7% response rate, the majority of participants were male (52%, had deceased donor transplants (63%, and received Medicare benefits (84%. PCS-12 was positively correlated with three of five KTQ subscales (P < 0.05, ie, KTQ-physical (r = 0.43, KTQ-fatigue (r = 0.42, and KTQ-uncertainty/fear (r = 0.2. MCS-12 was positively correlated

    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).

    We describe the donor tumor transmission of metastatic angiosarcomas to four transplant recipients through transplantation of deceased-donor organs, i.e. kidneys, lung and liver, from an apparently unaffected common female multiorgan donor. Fluorescent in situ hybridization of angiosarcoma cells...... confirmed that the tumor was of female donor's origin in male kidney recipients. Recent literature associated increased urokinase-plasminogen-activator-receptor (uPAR) and plasma soluble urokinase-plasminogen-activator-receptor (suPAR) levels with metastatic malignancies. Now we found that, compared...... to baseline levels, both deceased-donor kidney recipients showed increased uPAR transcripts in mononuclear cells as well as increased plasma suPAR levels after the diagnosis of metastatic angiosarcomas, i.e. 4 months after donor tumor transmission. These results show an association of uPAR/suPAR in donor...

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

    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.

    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.

    This study assessed relationships among internalizing symptoms, barriers to medication adherence, and medication adherence in adolescents with solid organ transplants. The sample included 72 adolescents who had received solid organ transplants. Multiple mediator models were tested via bootstrapping methods. Bivariate correlations revealed significant relationships between barriers and internalizing symptoms of depression, anxiety, and posttraumatic stress, as well as between internalizing symptoms and medication adherence. Barriers indicative of adaptation to the medication regimen (e.g., forgetting, lack of organization) were related to medication adherence and mediated the relationship between internalizing symptoms and medication adherence. These findings indicate that barriers may serve as a more specific factor in the relationship between more general, pervasive internalizing symptoms and medication adherence. Results may help guide areas for clinical assessment, and the focus of interventions for adolescent transplant recipients who are experiencing internalizing symptoms and/or who are nonadherent to their medication regimen.

    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.

    A high prevalence of posttraumatic stress disorder (PTSD) symptoms among transplant recipients has been associated with a low adherence to treatment and poor survival. It is crucial to detect and prevent the development of posttraumatic stress in transplant settings. We examined the prevalence of posttraumatic stress symptoms in 3 liver transplant recipients by means of the Essen Trauma Inventory (ETI), a self-report questionnaire. The Short Form-36 was used to assess the perceived health-related quality of life. Patients were asked to indicate the most traumatic events within the context of the liver transplantation procedure. Five patients (4.9%) fulfilled the criteria for PTSD related to liver disease or transplantation (ETI score greater than 27). In these patients, diagnosis was confirmed by a structured clinical interview. Fourteen (13.6%) patients had a partial PTSD with the ETI score less than 27 and greater than 16. Posttraumatic stress symptoms were significantly associated with perceived poor physical and mental health-related quality of life. Patients reported that the physicians' disclosure of diagnosis was experienced as traumatic, followed by treatment in an intensive care unit and the liver transplantation itself. The ETI resulted in prevalence rates for PTSD comparable to previous studies in liver transplantation settings. Medical professionals requested additional training in how to deliver severe diagnoses to patients.

    Full Text Available South Asian renal transplant recipients have a higher incidence of cardiovascular disease compared with Caucasian renal transplant recipients. We carried out a study to determine whether paraoxonase 1, a novel biomarker for cardiovascular risk, was decreased in South Asian compared with Caucasian renal transplant recipients. Subjects were matched two to one on the basis of age and sex for a total of 129 subjects. Paraoxonase 1 was measured by mass, arylesterase activity, and two-substrate phenotype assay. Comparisons were made by using a matched design. The frequency of PON1 QQ, QR and RR phenotype was 56%, 37%, and 7% for Caucasian subjects versus 35%, 44%, and 21% for South Asian subjects (χ2=7.72, P=0.02. PON1 mass and arylesterase activity were not significantly different between South Asian and Caucasian subjects. PON1 mass was significantly associated with PON1 phenotype (P=0.0001, HDL cholesterol (P=0.009, LDL cholesterol (P=0.02, and diabetes status (P<0.05. Arylesterase activity was only associated with HDL cholesterol (P=0.003. Thus the frequency of the PON1 RR phenotype was higher and that of the QQ phenotype was lower in South Asian versus Caucasian renal transplant recipients. However, ethnicity was not a significant factor as a determinant of PON1 mass or arylesterase activity, with or without analysis including PON1 phenotype. The two-substrate method for determining PON1 phenotype may be of value for future studies of cardiovascular complications in renal transplant recipients.

    Full Text Available Interleukin 18 (IL-18 is a proinflammatory cytokine that plays a role in host defense by upregulating both innate and acquired immune responses. Analysis of IL 18 polymorphisms may be clinically important since their roles have been recognized in a variety of inflammatory and autoimmune disorders. However, the role of this cytokine polymorphisms in kidney transplant still remains unclear. In this study, we evaluated the associations between IL 18 polymorphisms and graft function assessed by creatinine clearance in kidney transplant recipients. A total of 82 kidney transplant recipients and 183 healthy controls were enrolled, and frequencies of alleles, genotypes and haplotypes for IL 18 polymorphisms were determined and compared with creatinine clearance. The -607C/A (rs1946518 and -137C/G (rs187238 variant alleles in the 18 gene were determined by polymerase chain reaction. In our study, no significant association was found between the IL 18 variants and creatinine clearance (p > 0.05. Nonetheless, polymorphism analysis revealed an increase in the frequency of the IL18 major haplotype -607C/-137G in kidney transplant patients (odds ratio 2.57, 95% confidence interval 1.45-4.55, p = 0.0014. Finally, we found that IL 18 polymorphisms did not influence the renal function and that IL18 haplotype -607C/-137G seems to be associated with kidney transplant recipients.

    Full Text Available Background and objectives: 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. Methods: Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1 μg/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. Results: 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. Conclusions: Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits. Resumen: Antecedentes y objetivos: El paricalcitol, un activador selectivo del receptor de la vitamina D, se utiliza en el tratamiento del hiperparatiroidismo secundario en el receptor de trasplante renal.

    Vitamin D deficiency was shown to be prevalent among renal transplant recipients in northern countries, but little is known regarding risk factors. To test vitamin D levels in kidney transplant recipients residing closer to the equator, compare them to levels in liver transplant recipients and hemodialysis patients, and identify possible risk factors. In a cross-sectional study 103 kidney transplant recipients, 27 liver transplant recipients and 50 hemodialysis patients followed at our institute were tested for vitamin D levels. Demographic data, medical history and current treatment were recorded from the medical files. Inadequate vitamin D levels (Vitamin D levels were higher among dialysis patients than transplant recipients, though deficiency rates were similar. No association was found between kidney function and vitamin deficiency. Deficiency was associated with higher prednisone doses, use of mycophenolate sodium, tacrolimus, and iron supplements, or lower doses of vitamin D supplementation. Despite potential higher ultraviolet B exposure, inadequate vitamin D levels were prevalent in our study group. Importantly, some immunosuppressive medications were associated with vitamin D deficiency and high doses of vitamin D were associated with less deficiency.

    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 compatible transplants. ABO identical transplant recipients had a significantly higher 5-year graft survival rate than ABO compatible recipients (39% versus 21%, p compatible (N = 188, 11%) than in the early decade (p compatible 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

    effects (p=0.008) in renal transplant recipients receiving tacrolimus and mycophenolic acid compared to the cyclosporine regimen. This finding demonstrated construct validity. Intra-class correlation was 0.81 (95% confidence interval: 0.65-0.90) and Kappa statistic of 0.68 ± 0.25 for all 18 adverse effects and verified substantial inter-rater reliability. This immunosuppressive adverse effects scoring system in stable renal transplant recipients was evaluated and substantiated face, content and construct validity with inter-rater reliability. The scoring system may facilitate prospective, standardized clinical monitoring of immunosuppressive adverse drug effects in stable renal transplant recipients and improve medication adherence.

    Full Text Available Urinary tract infection (UTI is the most common complication following kidney transplantation (KT, which could result in losing the graft. This study aims to identify the prevalence of bacterial UTI among KT recipients in Yemen and to determine the predisposing factors associated with post renal transplantation UTI. A cross sectional study included of 150 patients, who underwent KT was conducted between June 2010 and January 2011. A Morning mid-stream urine specimen was collected for culture and antibiotic susceptibility test from each recipient. Bacterial UTI was found in 50 patients (33.3%. The prevalence among females 40.3% was higher than males 29%. The UTI was higher in the age group between 41-50 years with a percentage of 28% and this result was statistically significant. Predisposing factors as diabetes mellitus, vesicoureteral reflux, neurogenic bladder and polycystic kidney showed significant association. High relative risks were found for polycystic kidney = 13.5 and neurogenic bladder = 13.5. The most prevalent bacteria to cause UTI was Escherichia coli represent 44%, followed by Staphylococcus saprophyticus 34%. Amikacin was the most effective antibiotic against gram-negative isolates while Ciprofloxacin was the most effective antibiotic against Staphylococcus saprophyticus. In conclusion, there is high prevalence of bacterial UTI among KT recipients in Yemen. Diabetes mellitus, vesicoureteral reflux, neurogenic bladder, polycystic kidney and calculi were the main predisposing factors.

    To review the vascular anatomy of the donor and the recipient for the living kidney transplantation. The recent literature about the vessels of donor and recipient in clinical applications was extensively reviewed. The pertinent vascular anatomy of the donor and recipient was essential for the screening of the proper candidates, surgical planning and long-term outcome. Early branching and accessory renal artery of the donor were particularly important to deciding the side of nephrectomy, surgical technique and anastomosing pattern, and their injuries were the most frequent factor of the conversion from laparoscopic to open surgery. With increase of laparoscopic nephrectomy in donors, accurate venous anatomy was paid more and more attention to because venous bleeding could also lead to conversion to open nephrectomy. Multidetector CT (MDCT) could supplant the conventional excretory urography and renal catheter angiography and could accurately depict the donors' vessels, vascular variations. In addition, MDCT can excellently evaluate the status of donor kidney, collecting system and other pertinent anatomy details. Accurate master of related vascular anatomy can facilitate operation plan and success of operation and can contribute to the rapid development of living donor kidney transplantation. MDCT has become the choice of preoperative one-stop image assessment for living renal donors.

    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

    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.

    Owing to limited availability of donor organs, previous solid organ transplant (SOT) recipients are increasingly considered as potential organ donors. We report donor-derived transmission of herpes simplex virus type-2 (HSV-2) to two clusters of SOT recipients with transmission from the original donor and an HSV-2-infected recipient who subsequently became a donor. We reviewed medical records of the donors and recipients in both clusters. Pre-transplant serology and virological features of HSV-2 were characterized. Genotyping of HSV-2 isolates to determine potential for donor transmission of HSV-2 through transplantation of organs from prior organ recipients was performed. A kidney-pancreas recipient died day 9 post transplant. Following confirmation of brain death, the lungs and recently transplanted kidney were donated to two further recipients. The liver was not retrieved, but biopsy confirmed HSV-2 infection. Testing on the original donor showed negative HSV-2 polymerase chain reaction and HSV immunoglobulin (Ig)M, but positive HSV-2 IgG. The liver recipient from the original donor developed HSV-2 hepatitis and cutaneous infection that responded to treatment with intravenous acyclovir. In the second cluster, lung and kidney recipients both developed HSV-2 viremia that was successfully treated with antiviral therapy. Genotyping of all HSV-2-positive samples showed 100% sequence homology for three recipients. Donor-derived HSV infection affected two clusters of recipients because of transplantation of organs from a prior organ recipient. HSV should be considered as a possible cause of illness in febrile SOT recipients in the immediate post-transplant period and may cause disseminated disease and re-infection in HSV-2-seropositive recipients. Testing of HSV serology and prophylaxis may be considered in SOT recipients not receiving cytomegalovirus prophylaxis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Kidney transplant recipients require lifelong treatment with immunosuppressive medications to avoid graft rejection and graft loss. Symptoms experienced may influence recipients' perceived quality of life and medication adherence. The purpose of this study was to evaluate the symptom experience associated with immunosuppressive medications in adult kidney transplant recipients and to explore the association between the symptom experience and adherence to immunosuppressive medications. A cross-sectional design was used. The study was conducted in a general hospital in China from October 2013 to September 2014. A total of 231 recipients with a follow-up of at least 1 year after kidney transplantation were included. Symptom experience associated with immunosuppressive medications was measured by the 13-item Symptom Experience of Immunosuppressive-related Side Effects Scale. Self-reported adherence to immunosuppressive medications was assessed using the Adherence with Immunosuppressive Medication Scale. Ridit analysis was used to rank symptom distress items. A proportion of 60.6% of recipients were male; the time after kidney transplantation was arbitrarily divided into a short-term cohort (1-4 years) and a long-term cohort (4-16 years) according to the median duration of follow-up (4 years). High blood pressure, hair loss, and tiredness were the three most distressing symptoms over all items of the whole sample. High blood pressure was the most distressing symptom for the 1- to 4-year cohort and the 4- to 16-year cohort. For men high blood pressure was the most distressing symptom, whereas for women hair loss was the most distressing symptom. Recipients in the 4- to 16-year cohort perceived a higher level of symptom distress compared with those in the 1- to 4-year cohort, especially in excess hair growth and difficulty sleeping. A negative relationship was found between symptom distress and adherence to immunosuppressive medications (r = -.541, p = .000). Recipients

    The effect of donor-recipient sex matching on long-term survival in pediatric heart transplantation is not well known. Adult data have shown worse survival when male recipients receive a sex-mismatched heart, with conflicting results in female recipients. We analyzed 5795 heart transplant recipients ≤ 18 yr in the Scientific Registry of Transplant Recipients (1990-2012). Recipients were stratified based on donor and recipient sex, creating four groups: MM (N = 1888), FM (N = 1384), FF (N = 1082), and MF (N = 1441). Males receiving sex-matched donor hearts had increased unadjusted allograft survival at five yr (73.2 vs. 71%, p = 0.01). However, this survival advantage disappeared with longer follow-up and when adjusted for additional risk factors by multivariable Cox regression analysis. In contrast, for females, receiving a sex-mismatched heart was associated with an 18% higher risk of allograft loss over time compared to receiving a sex-matched heart (HR 1.18, 95% CI: 1.00-1.38) and a 26% higher risk compared to sex-matched male recipients (HR 1.26, 95% CI: 1.10-1.45). Females who receive a heart from a male donor appear to have a distinct long-term survival disadvantage compared to all other groups. © 2015 John Wiley & Sons A/S.

    To quantify physical activity and grip strength in pediatric kidney transplant recipients and describe attitudes about exercise and exercise counseling given concerns about allograft injury. This was a cross-sectional analysis of 101 kidney transplant recipients (7-21 years old) >6 months post-transplant. Patients completed the Physical Activity Questionnaire (PAQ). Grip strength was measured with a dynamometer. We asked about activity limitations and provider counseling. Univariate analysis and multiple linear regression were used to determine independent predictors of PAQ score and grip strength z score. We enrolled 101 of 122 eligible patients. Median PAQ score was 2.2 (range 0-5) and was lower compared with controls (P < .001). The average grip strength z score was -1.1 and -0.7 in the right and left hand, respectively. Predictors of lower grip strength were younger age (P = .036), non-African American race (P = .029), lower height z score (P = .010), and longer percentage of lifetime with kidney disease (P = .029). Although 49% and 67% limited exercise before and after transplant, respectively, 67% reported increased activity after transplant. By parent report, provider counseling included limiting certain activities (71%) and encouraging regular exercise (45%). Physical activity and grip strength are low after kidney transplant. Patients perceive an emphasis on exercise limitations rather than the benefits of regular exercise. Interventions that encourage physical activity may be beneficial. Copyright © 2016 Elsevier Inc.

    BK polyomavirus (BKV) is an opportunist agent associated with nephropathy (BKVAN) in 1-10% of kidney transplant recipients. BKV is classified into genotypes or subgroups according to minor nucleotidic variations with unknown biological implications. Studies assessing the possible association between genotypes and the risk of BKVAN in kidney transplant patients have presented conflicting results. In these studies, genotype Ia, which is highly prevalent in Brazil, was less frequently found and, thus, comparative data on the biological properties of this genotype are lacking. In this study, BKV Ia and Ib1 genotypes were compared according to their viral load, genetic evolution (VP1 and NCCR) - in a cohort of renal transplant recipients. The patients infected with Ia (13/23; 56.5%) genotype exhibited higher viral loads in urine [>1.4 log over Ib1 (10/23; 43.5%); p=0.025]. In addition, genotype Ia was associated with diverse mutations at VP1 loops and sites under positive selection outside loops, which were totally absent in Ib1. Although the number of viremic patients was similar, the three patients who had BK nephropathy (BKVAN) were infected with Ia genotype. NCCR architecture (ww or rr) were not distinctive between Ia and Ib1 genotypes. Ia genotype, which is rare in other published BKV cohorts, presented some diverse biological properties in transplanted recipients in comparison to Ib1. Copyright © 2017 Elsevier B.V.

    Objective To investigate the expressions of serum soluble human leukocyte antigen G (sHLA-G) and soluble CD30 (sCD30) in renal transplant recipients at different time after transplantation, and explore the relationship between the expressions of serum sHLA-G, sCD30 and the time after renal transplantation. Methods Eleven kidney transplant recipients and 10 healthy donors were selected, in which the dynamic changes of serum sHLA-G and sCD30 were detected by ELISA before transplantation and 1 year after transplantation; 33 kidney transplant recipients with normal renal graft were selected and divided into three groups: 1-5 years, 5-10 years and 10 years post-transplantation. The expressions of serum sHLA-G and sCD30 in the recipients were tested over one year after transplantation. Results The level of serum sHLA-G before transplantation was not significantly different from that of the control group. There was no significant difference between pre-transplantation, 1 week and 1 month after transplantation. Serum sHLA-G level of renal transplant recipients at 3 months after transplantation was higher than that 1 month after transplantation. There was no significant change in serum sHLA-G level among 3, 6 and 12 months after transplantation. The level of serum sHLA-G in the group of transplant time >10 years was significantly higher than that in the group of transplant time ≤5 years. The serum sHLA-G level was significantly associated with the time after renal transplantation. The level of serum sCD30 before transplantation was higher than that in the control group and decreased in 1 week after transplantation. There were no significant differences in sCD30 level between 1, 3, 6, and 12 months after transplantation, and similarly, there were also no significant differences between the groups of transplant time ≤5 years, 5-10 years and 10 years after transplantation. The level of sCD30 was significantly associated with the time within 1 month after renal

    Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1(st) Department of Obstetrics and Gynecology, Medical University of Warsaw. The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group (P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

    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.

    Achieving optimum outcomes after liver transplantation requires an understanding of the interaction between donor, graft and recipient factors. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes and benefit the overall waiting list by minimizing graft failure and need for re-transplantation. A PubMed search was conducted to identify published literature investigating the effects of donor factors such as ...

    Full Text Available BACKGROUND: The advances in surgical techniques and immunosuppression have improved results in organ transplantation which enabled pregnancies following the return of good health and normal endocrine function. Reports about the anesthetic management of renal transplant recipient (RTR during cesarean section (C/S were not found in the literature. The aim of this study is to present our experience in RTRs during C/S. MATERIALS-METHODS: Retrospect ive data regarding RTRs who underwent C/S among 1645 renal transplantations at Baskent Univer sity Hospital in Ankara between January 1977 and Decem ber 2007 have been collected from hospital records. RESULTS: Eleven live births occured from ten RTRs. Two of them from vaginal delivery and 9 from C/S. The mean maternal age was 28 ± 4.6 years. The time from transplantation to conception was 41.1 ± 30.4 months. The mean gestational age was 33.5 ± 3.6 weeks and all recipients were maintained on cyclosporine, azathioprine and corticosteroids before and during pregnancy for immunosuppression. Five C/Ss were performed under general anesthesia whereas spinal anesthesia was used in 4 patients. Renal function tests were stable in all of the patients and we did not observe any acute rejection. The mean birth weight was 1945 ± 689 gr. There were 7 premature and 7 low birth weight among 11 newborns. CONCLUSION: General and regional anesthesia can be safely used during cesarean delivery of the RTRs without increased risk of graft loses. Prematurity and low birth weight was mainly due to the cytotoxic drugs for immunosuppression. Perioperative management of RTRs should be handled by a team including anesthesiologists.

    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.

    Human herpesvirus 6 (HHV-6) species have a unique ability to integrate into chromosomal telomeres. Mendelian inheritance via gametocyte integration results in HHV-6 in every nucleated cell. The epidemiology and clinical effect of inherited chromosomally integrated HHV-6 (iciHHV-6) in hematopoietic cell transplant (HCT) recipients is unclear. We identified 4319 HCT donor-recipient pairs (8638 subjects) who received an allogeneic HCT and had archived pre-HCT peripheral blood mononuclear cell samples. We screened these samples for iciHHV-6 and compared characteristics of HCT recipients and donors with iciHHV-6 with those of recipients and donors without iciHHV-6, respectively. We calculated Kaplan-Meier probability estimates and Cox proportional hazards models for post-HCT outcomes based on recipient and donor iciHHV-6 status. We identified 60 HCT recipients (1.4%) and 40 donors (0.9%) with iciHHV-6; both recipient and donor harbored iciHHV-6 in 13 HCTs. Thus, there were 87 HCTs (2%) in which the recipient, donor, or both harbored iciHHV-6. Acute graft-versus-host disease (GVHD) grades 2-4 was more frequent when recipients or donors had iciHHV-6 (adjusted hazard ratios, 1.7-1.9; P = .004-.001). Cytomegalovirus viremia (any and high-level) was more frequent among recipients with iciHHV-6 (adjusted HRs, 1.7-3.1; P = .001-.040). Inherited ciHHV-6 status did not significantly affect risk for chronic GVHD, hematopoietic cell engraftment, overall mortality, or nonrelapse mortality. Screening for iciHHV-6 could guide donor selection and post-HCT risk stratification and treatment. Further study is needed to replicate these findings and identify potential mechanisms. © 2017 by The American Society of Hematology.

    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.

    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.

  1. Diabetic ketoacidosis associated with tacrolimus in solid organ transplant recipients

    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)

    The aim of the present large population-based cohort study is to explore the risk factors of age-related mortality in liver transplant recipients in Taiwan. Basic information and data on medical comorbidities for 2938 patients who received liver transplants between July 1, 1998, and December 31, 2012, were extracted from the National Health Insurance Research Database on the basis of ICD-9-codes. Mortality risks were analyzed after adjusting for preoperative comorbidities and compared among age cohorts. All patients were followed up until the study endpoint or death. This study finally included 2588 adults and 350 children [2068 (70.4%) male and 870 (29.6%) female patients]. The median age at transplantation was 52 (interquartile range, 43-58) years. Recipients were categorized into the following age cohorts: recipients (≥60 years), especially dialysis patients, have a higher mortality rate, possibly because they have more medical comorbidities. Our findings should make clinicians aware of the need for better risk stratification among elderly liver transplantation candidates.

    New-onset diabetes mellitus (NODM) after liver transplantation (LT) occurs with increased frequency in recipients with hepatitis C virus (HCV). We compared the incidence and risk factors for NODM in HCV vs non-HCV recipients. Among 24,956 liver recipients, 18,741 without pretransplantation diabetes were identified. NODM-free survival was analyzed using Kaplan-Meier and log-rank tests, and risk factors for NODM were examined using multivariate Cox regression analysis. The overall incidence of NODM was 13.0% at 1 year after LT. At 1, 2, 3, and 5 years after LT, incidence of NODM in HCV recipients was 14.4%, 4.3%, 3.1%, and 3.5%, respectively, compared with 11.9%, 3.5%, 3.2%, and 6.4%, respectively, in non-HCV recipients. HCV recipients had a higher risk of NODM than non-HCV recipients (hazard ratio 1.17 [1.09-1.27], P diabetes mellitus. Risk factors in non-HCV recipients were male recipient, BMI, and recipients with nonalcoholic steatohepatitis diagnosis. HCV recipients have a higher incidence and more risk factors for NODM than non-HCV recipients. Early identification of modifiable risk factors will assist clinical interventions to prevent NODM complications after LT. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

    Studies have shown that arecoline, the major alkaloid component of betel nuts, alters the activity of enzymes in the cytochrome P450 (CYP-450) family. Tacrolimus, an immunosuppressant that protects against organ rejection in transplant recipients, not only is mainly metabolized by CYP3A enzymes but also has a narrow therapeutic range. We aimed to investigate whether dose-adjusted blood trough levels of tacrolimus differed over time between betel nut-chewing and non-betel nut-chewing liver transplant recipients. In this retrospective case-control study, 14 active betel nut-using liver recipients were matched at a 1:2 ratio to 28 non-betel nut-using liver recipients by sex, age, graft source, duration of follow-up after liver transplantation, and estimated glomerular filtration rate. Differences in liver function index, renal function index, and dose-adjusted blood trough levels of tacrolimus over an 18-month period were compared between the 2 groups by using the Generalized Estimating Equation approach. Dose-adjusted blood trough levels of tacrolimus tended to be significantly (P = .04) lower in betel nut chewers (mean = 0.81, medium = 0.7, 95% confidence interval [CI] = 0.73 to 0.90) than in nonchewers (mean = 1.12, medium = 0.88, 95% CI = 1.03 to 1.22) during the 18-month study period. However, there was no significant difference in renal and liver function index between the 2 groups. Liver transplant recipients receiving tacrolimus tend to have lower blood trough levels of the drug over time if they chew betel nuts. Copyright © 2016 Elsevier Inc. All rights reserved.

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

    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.

    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.

    Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and post-transplant patient care and rehabilitation researchers. PMID:27683630

    The association between pre-transplant mental health concerns and non-adherence and post-transplant outcomes after kidney transplantation is not fully established. We examined the relationship between a pre-transplant history of mental health concerns and non-adherence and post-transplant outcomes among kidney transplant recipients. In this retrospective single center cohort study of adult kidney transplant recipients (n=955) the associations between the history of mental health concerns or non-adherence and the time from kidney transplant to biopsy proven acute rejection; death-censored graft failure and total graft failure were examined using Cox proportional hazards models. Mean (SD) age was 51 (13) years, 61% were male and 27% had a history of diabetes. Twenty-two and 11% of patients had mental health concerns and non-adherence, respectively. Fifteen percent of the patients had acute rejection, 5.6% had death-censored graft failure and 13.0% had total graft failure. The history of mental health concerns was not associated with acute rejection, death-censored graft failure or total graft failure. Patients with versus without a history of non-adherence tended to have higher cumulative incidence of acute rejection (23.3% [95% CI: 16.1, 33.2] vs. 13.6% [95% CI: 11.4, 16.2]) and death-censored graft failure (15.0% [95% CI: 6.9, 30.8] vs. 6.4% [95% CI: 4.7, 8.7]) (log rank p=0.052 and p=0.086, respectively). These trends were not significant after multivariable adjustment. In summary, a history of pre-transplant mental health concerns or non-adherence is not associated with adverse outcomes in patients who completed transplant workup and received a kidney transplant.

    Full Text Available Aim: Patients with a solid organ transplant can have many different complications in the mouth, as a result of immunosuppression and side effects of drugs. The aim of this study was to examine the frequency and type of oral lesions in renal transplant patients, dental status, oral hygiene, oral lesions related to drugs which patients take and the time of transplantation as well as the frequency of patient’s visits to the dentist in the post-transplant period. Material and methods: The study was performed in a period of two years and included 100 subjects with a renal transplant during their regular control visits to the Department of Nephrology and Dialysis, Clinical Hospital Centre Zagreb and the Department of Oral Medicine, School of Dental Medicine, University of Zagreb and 100 randomly selected control subjects at the Department of Endodontics and Restorative Dentistry, School of Dental Medicine, University of Zagreb. Results: Results showed a significantly higher incidence of oral lesions in patients with renal transplant (31% compared to control subjects. The most frequent were erythematous (inflammatory changes, keratotic lesions and gingival hyperplasia. The average DMFT index was significantly lower in patients with renal transplant than in the control group. One third of patients had a subjective feeling of dry mouth. Oral hygiene was poor overall, and only a small number of subjects used the additional sustainers for oral hygiene. Most patients did not visit the dentist after the transplantation. Conclusion: Renal transplant patients need a comprehensive and regular dental care during the pre- and post-transplant period and a doctor of dental medicine should be part of a multidisciplinary team of medical specialists.

    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 (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

    There is accumulating evidence of structural sympathetic reinnervation after human cardiac transplantation. However, the functional significance of reinnervation in terms of exercise capacity has not been established as yet; we therefore investigated the influence of reinnervation on cardiopulmonary exercise testing. After orthotopic heart transplantation 35 patients (mean age, 49.1 +/- 8.4 years) underwent positron emission tomography with scintigraphically measured uptake of C11-hydroxyephedrine (HED), lung function testing, and cardiopulmonary exercise testing. Two groups were defined based on scintigraphic findings, indicating a denervated group (n = 15) with a HED uptake of 5.45%/min and a reinnervated group (n = 20) with a HED uptake of 10.59%/min. The two study groups did not show significant differences with regard to anthropometric data, number of rejection episodes, preoperative hemodynamics, and postoperative lung function data. The reinnervated group had a significant longer time interval from transplantation (1625 +/- 1069 versus 800 +/- 1316 days, p exercise (137 +/- 15 versus 120 +/- 20 beats/min, p = .012), peak oxygen uptake (21.0 +/- 4 versus 16.1 +/- 5 mL/min/kg, p = .006), peak oxygen pulse (12.4 +/- 2.9 versus 10.2 +/- 2.7 mL/min/beat, p = .031), and anaerobic threshold (11.2 +/- 1.8 versus 9.5 +/- 2.1 mL/min, p = .046) were significantly increased in comparison to denervated transplant recipients. Additionally, a decreased functional dead space ventilation (0.24 +/- 0.05 versus 0.30 +/- 0.05, p = .004) was observed in the reinnervated group. Our study results support the hypothesis that partial sympathetic reinnervation after cardiac transplantation is of functional significance. Sympathetic reinnervation enables an increased peak oxygen uptake. This is most probably due to partial restoration of the chronotropic and inotropic competence of the heart as well as an improved oxygen delivery to the exercising muscles and a reduced ventilation

    To study the incidence, types and distribution pattern of malignant tumors in renal transplant recipients at a single center in Pakistan. This retrospective study was conducted at Sindh Institute of Urology and Transplantation (SIUT) and included all transplant patients on regular follow-up from November 1986 to December 2008. The original biopsy reports and case files of all patients who developed posttransplant malignancies were reviewed and relevant demographic, clinical, radiological, and histopathological data were retrieved and analyzed. SPSS version 10.0 was used for statistical analysis. Over 22 years of study period, 1816 renal transplants were carried out at our center. Among these, 44 patients developed malignancies constituting an overall incidence rate of 2.4%. All patients in this study were males with a mean age of 34.9±9.5 years (range: 9 to 60 years). The most common type of malignancy was lymphoma (27 patients, 61.4%), followed by Kaposi's sarcoma (11 patients, 25%) and skin malignancies (3 patients, 6.8%). One case each of adenocarcinoma of the gallbladder, acute myeloid leukemia (AML), conjunctival carcinoma-in-situ and seminoma were also diagnosed. Posttransplant malignancies occurring in our renal transplant recipients show different incidence rates and patterns as compared with western studies.

    Background Health literacy (HL) may be a mediator for known socioeconomic and racial disparities in living kidney donation. Methods We evaluated the associations of patient and demographic characteristics with HL in living kidney donors (LD), living donor kidney transplant recipients (LDR), and deceased donor recipients (DDR) in a single center retrospective review of patients undergoing kidney donation or transplantation from September 2010 to July 2012. HL and demographic data were collected. HL was assessed via the Short Literacy Survey (SLS) comprising three self-reported screening questions scored using the 5-point Likert scale [low (3-8), moderate (9-14), high (15)]. Chi-square and logistic regression were used to test factors associated with lower HL. Results The sample included 360 adults (105 LD, 103 LDR, 152 DDR; 46±14 years; 70% white; 56% male; 14±3 years of education). HL scores were skewed (49% high, 41% moderate, 10% low). The distribution of HL categories differed significantly among groups (p=0.019). After controlling for age, race, gender, education and a race-education interaction term, DDR were more likely to have moderate or low HL than LDR (OR 1.911; 95%CI 1.096, 3.332; p=0.022) Conclusions Overall, living donors had high HL. The distribution of low, moderate and high HL differed significantly between LD, DDR and LDR. DDR had a higher likelihood of having low HL than LDR. Screening kidney transplant candidates and donors for lower HL may identify barriers to living donation. Future interventions addressing HL may be important to increase living donation and reduce disparities. PMID:24573114

    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.

    Prolonged-release tacrolimus was developed as a once-daily formulation with ethylcellulose as the excipient, resulting in slower release and reduction in peak concentration (Cmax ) for a given dose compared with immediate-release tacrolimus, which is administered twice daily. This manuscript reviews pharmacokinetic information on prolonged-release tacrolimus in healthy subjects, in transplant recipients converted from immediate-release tacrolimus, and in de novo kidney and liver transplant recipients. As with the immediate-release formulation, prolonged-release tacrolimus shows a strong correlation between trough concentration (Cmin ) and area under the 24-hour time-concentration curve (AUC24 ), indicating that trough whole blood concentrations provide an accurate measure of drug exposure. We present the pharmacokinetic similarities and differences between the two formulations, so that prescribing physicians will have a better understanding of therapeutic drug monitoring in patients receiving prolonged-release tacrolimus. © 2016 John Wiley & Sons A/S.

    2017-01-01

    Sugammadex is a novel pharmacologic agent that is used to selectively reverse the effects of the neuromuscular blocking agents rocuronium and vecuronium. Various advantages have been reported when comparing its reversal of neuromuscular blockade to that achieved with acetylcholinesterase inhibitors (neostigmine). In heart transplant recipients, bradycardia may occur following the administration of acetylcholinesterase inhibitors, due to the denervation of the heart. Theoretically, the combination of rocuronium and sugammadex could be advantageous in this clinical scenario to avoid the potential bradycardia resulting from neostigmine administration. We present a 10-year-old male who developed profound bradycardia immediately following the administration of intravenous sugammadex. The options for reversal of neuromuscular blockade in heart transplant recipients is discussed, previous reports of bradycardia following sugammadex are presented, and the role of sugammadex in the bradycardia in our patient is reviewed.

    Full Text Available Background. Fasting during the lunar month of Ramadan is mandatory to all healthy adult Muslims. Renal transplant recipients are often worried about the impact of fluid and electrolyte deprivation during fasting on the function of their allograft. We aimed to examine the effect of fasting Ramadan on the graft function in renal transplant recipients. Methods. This retrospective cohort study included patients who underwent kidney transplantation in our tertiary referral center. Baseline pre-Ramadan estimated glomerular filtration rate (eGFR, mean arterial pressure (MAP, and urinary protein excretion were compared to those during and after Ramadan within and between the fasting and non-fasting groups. Results. The study population included 280 kidney transplant recipients who chose to fast during the Ramadan month (June-July 2014 and 285 recipients who did not fast. In the fasting group, baseline eGFR did not change from that during or post-Ramadan (72.6±23.7 versus 72.3±24.5 mL/min/1.73 m2, P=0.53; and 72.6±23.7 versus 72±23.2 mL/min/1.73 m2, P=0.14, respectively. Compared to baseline, there were no significant differences between the fasting and the non-fasting groups in terms of mean percent changes in eGFR, MAP, and urinary protein excretion. Conclusion. Fasting during the month of Ramadan did not have significant adverse effects on renal allograft function.

    Nonadherence to immunosuppressant medication is a prevalent practice among kidney transplant recipients and has been associated with increased risk for graft failure and economic burden. The aim of this pilot study was to test whether a culturally sensitive cognitive-behavioral adherence promotion program could significantly improve medication adherence to tacrolimus prescription as measured by telephone pill counts among kidney transplant recipients. Thirty-three adult transplant recipients were less than 98% adherent to tacrolimus prescription based on 3 telephone pill counts and were randomized either to the 2-session cognitive-behavioral adherence promotion program or to standard care. The curriculum was developed from an iterative process with transplant recipients into a 2-session group program that provided psychoeducation, addressed barriers to adherence, fostered motivation to improve adherence behavior, and discussed cultural messages on adherence behavior. The intervention group displayed significantly higher levels of adherence when compared to the control group (t = 2.2, p = 0.04) and. similarly, when the amount of change was compared between the groups, the intervention group showed more change than the control condition (F (22,1) = 12.005, p = 0.003). Tacrolimus trough concentration levels were used as a secondary measure of adherence and, while there were no significant between-group differences for mean trough concentration levels, the variability in the trough levels did significantly decrease over time indicating more consistent pill-taking behavior in the intervention group. There is preliminary support for the pilot program as a successful intervention in helping patients with their immunosuppressant medication. © 2016 S. Karger AG, Basel.

    Background and Aims:Hepatitis C virus (HCV) cirrhosis is the leading indication for liver transplantation in the United States and recurrent HCV following liver transplantation is a major cause of allograft loss and mortality.Liver biopsies are commonly used to identify recurrent HCV and determine the need for antiviral therapy.The introduction of directacting antiviral agents (DAAs) has changed the management of recurrent HCV infection.This study aimed to describe the role of liver biopsies in liver transplant recipients with HCV after the introduction of DAAs.Methods:A retrospective analysis was performed looking at the rate of liver biopsies post-liver transplantation for HCV.The analysis included 475 adult liver transplants for hepatitis C performed at the University of California,Los Angeles from January 1,2006 to October 1,2015.Patients were divided into two eras,pre-and post-introduction of DAAs on December 1,2013.Results:In the era before the introduction of DAAs,the percentage of patients biopsied was significantly higher compared to the era after the introduction of DAAs (56.1% vs.26.9%,p < 0.001).Conclusion:The introduction of DAAs has changed the management of liver biopsy following liver transplantation and the management of recurrent HCV.Given that DAAs are well tolerated and have high efficacy,liver biopsies are no longer routinely used to justify the use antiviral therapy following liver transplantation.

    Full Text Available Little is known about the influence of pre-transplant comorbidities on post-transplant expenditures. We estimated the associations between pre-transplant comorbidities and post-transplant Medicare costs, using several comorbidity classification systems. We included recipients of first-kidney deceased donor transplants from 1995 through 2002 for whom Medicare was the primary payer for at least one year pre-transplant (N = 25,175. We examined pre-transplant comorbidities as classified by International Classification of Diseases (ICD-9-CM codes from Medicare claims with the Clinical Cla-ssifications Software (CCS and Charlson and Elixhauser algorithms. Post-transplant costs were calcu-lated from payments on Medicare claims. We developed models considering Organ Procurement and Transplantation Network (OPTN variables plus: 1 CCS categories, 2 Charlson, 3 Elixhauser, 4 num-ber of Charlson and 5 number of Elixhauser comorbidities, independently. We applied a novel regression methodology to account for censoring. Costs were estimated at individual and population levels. The comorbidities with the largest impact on mean Medicare payments included cardiovascular disease, ma-lignancies, cerebrovascular disease, mental conditions and functional limitations. Skin ulcers and infec-tions, rheumatic and other connective tissue disease and liver disease also contributed to payments and have not been considered or described previously. A positive graded relationship was found between costs and the number of pre-transplant comorbidities. In conclusion, we showed that expansion beyond the usually considered pre-transplant comorbidities with inclusion of CCS and Charlson or Elixhauser comorbidities increased the knowledge about comorbidities related to augmented Medicare payments. Our expanded methodology can be used by others to assess more accurately the financial implications of renal transplantation to Medicare and individual transplant centers.

    To obtain an understanding of how health professionals support the kidney transplant patient to take their medications as prescribed long term. Kidney transplantation requires stringent adherence to complex medication regimens to prevent graft rejection and to maintain general well-being. Medication nonadherence is common in kidney transplantation, emerging in the first few months post-transplantation, leading to poor patient outcomes. Exploratory qualitative design. Five focus groups were conducted with a total of seven renal nurse transplant coordinators, two renal transplant nurse unit managers, seven nephrologists, seven pharmacists, four social workers, and one consumer representative representing all five hospitals offering adult kidney transplantation in Victoria, Australia in 2014. The views of two general practitioners who were unable to attend the focus groups were incorporated into the data set. All data underwent thematic analysis. Analysis revealed that adherence was a collective responsibility involving the whole of the transplant team and the patient via education blitz in hospital, identifying and managing nonadherence, promotion of self-advocacy, and the partnership between the patient and health professional. Patients were directed how to take their complex medications to be self-empowered, yet the partnership between the patient and health professional limited the patient's voice. Although medication adherence was a collective responsibility, communication was often one-way chiefly as a result of staffing and time constraints, hindering effective partnerships necessary for medication adherence. Expert skills in communication and adherence counselling are necessary to identify barriers affecting medication adherence. Patients need to be systematically screened, prepared and supported long-term within an accommodating healthcare system for the reality of caring for their transplanted kidney. Kidney transplant recipients require systematic

    Full text: Combined renal/pancreas transplantation is used in patients with severe type-1 diabetes and renal failure. Many patients have asymptomatic coronary artery disease (CAD). Thus, myocardial perfusion imaging (MPI) is widely used for preoperative risk assessment, however, its value has recently been challenged. The purpose of this study was to determine the predictive value of MPI compared to coronary angiography and/or thirty day perioperative cardiac events (cardiac death, myocardial infarction and unstable angina). We reviewed the MPI in 132 patients that were referred for possible renal pancreas transplantation during the period between 1987 - June 1997. Fifty five patients were excluded because of: still awaiting transplantation (n=19) ongoing medical assessment (n=21), received kidney only transplant (n=6) or other factors (n=9). Thus, 77 patients form the basis of this report. Seventy one patients were transplanted, 5 had coronary angiography and one died before transplantation but with coronary anatomy defined at autopsy. All patients (39 male, 38 female; mean age 37 years) had Tl-201 or Tc-99m MIBI SPECT at Westmead (n=54) or elsewhere (n=23). Patients underwent MPI, a mean of 12.1 months before transplantation and a mean of 6 months before coronary angiography or autopsy. MPI was normal in 64 (83%) and abnormal in 13 (17%) patients. Of the abnormal MPI, 7 patients had CAD and one had unstable angina post-operatively (PPV = 8/13; 61%). One patient had a fixed defect post CABG but proceeded to transplant with-out event; the other 4 patients had normal coronary anatomy. Of the normal MPIs there were no transplant related cardiac events, but one patient required CABG >12 months post MPI and a further patient died >12 months post transplant and was shown to have CAD at autopsy (NPV=62/64;97%). In conclusion we have found an excellent NPV and an acceptable PPV for MPI in potential renal pancreas graft recipients

    Current trends in immunosuppressive therapies for renal transplant recipients are reviewed. The common premise for immunosuppressive therapies in renal transplantation is to use multiple agents to work on different immunologic targets. The use of a multidrug regimen allows for pharmacologic activity at several key steps in the T-cell replication process and lower dosages of each individual agent, thereby producing fewer drug-related toxicities. In general, there are three stages of clinical immunosuppression: induction therapy, maintenance therapy, and treatment of an established acute rejection episode. Only immunosuppressive therapies used for maintenance therapy are discussed in detail in this review. The most common maintenance immunosuppressive agents can be divided into five classes: (1) the calcineurin inhibitors (CNIs) (cyclosporine and tacrolimus), (2) costimulation blockers (belatacept), (3) mammalian target of rapamycin inhibitors (sirolimus and everolimus), (4) antiproliferatives (azathioprine and mycophenolic acid derivatives), and (5) corticosteroids. Immunosuppressive regimens vary among transplantation centers but most often include a CNI and an adjuvant agent, with or without corticosteroids. Selection of appropriate immunosuppressive regimens should be patient specific, taking into account the medications' pharmacologic properties, adverse-event profile, and potential drug-drug interactions, as well as the patient's preexisting diseases, risk of rejection, and medication regimen. Advancements in transplant immunosuppression have resulted in a significant reduction in acute cellular rejection and a modest increase in long-term patient and graft survival. Because the optimal immunosuppression regimen is still unknown, immunosuppressant use should be influenced by institutional preference and tailored to the immunologic risk of the patient and adverse-effect profile of the drug.

    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.

    Full Text Available The article provides the overview of current international recommendations dedicated to selection of heart transplantation recipients based on urgency status. Authors found that cardiopulmonary bicycle stress test allowed to reveal additional criteria of high death risk within 1 year. These additional criteria were: the maximal oxygen consumption VO2max < 30% of the expected considering the age; VD/VT (ratio of physiologic dead space over tidal volume increasing during the test; maximal tolerance to physical loading ≤50 Wt and/or < 20% of the expected considering the age. Authors created mathematical model for prediction of death within 1 year based on above mentioned data. Special software estimating the probability of death within 1 year was also created.

    Cellulitis is an unusual presentation of cryptococcal infection in renal allograft recipients. In such patients, disseminated cryptococcal infection can result in significant morbidity and mortality. Patients are often treated with antibiotics before a definitive diagnosis is made, delaying appropriate therapy. We describe the case of a 43-year-old post renal transplant recipient presenting with fever and swelling in the right thigh. On physical examination, the patient was found to have features suggestive of cellulitis with minimal slurring of speech. Material obtained from incision and drainage of the wound showed yeast cells resembling Cryptococcus spp. Blood culture and cerebrospinal fluid culture were also found to have growth of Cryptococcus neoformans. He received treatment with amphotericin B 6 mg/kg daily intravenously for two weeks, then continued with fluconazole 400 mg daily for three months. The patient showed a remarkable improvement. There was no recurrence of cryptococcosis after four months of follow-up. The diagnosis of disseminated cryptococcosis should be considered in differential diagnosis of cellulitis among non HIV immunocompromised hosts. A high clinical suspicion and early initiation of therapy is needed to recognize and treat patients effectively.

    BACKGROUND: 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. METHODS: 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. RESULTS: Sixteen HTx recipients (mean age 52 years, 75% male) completed the study. HIIT increased VO2peak more than CON (between-group difference, p

    Anemia, iron deficiency anemia (IDA), and iron deficiency (ID) are highly prevalent in renal transplant recipients (RTR). Anemia is associated with poor outcome, but the role of ID is unknown. Therefore, we aimed to investigate the association of ID, irrespective of anemia, with all-cause mortality in RTR. Cox regression analyses were used to investigate prospective associations. In 700 RTR, prevalences of anemia, IDA, and ID were 34%, 13%, and 30%, respectively. During follow-up for 3.1 (2.7-3.9) years, 81 (12%) RTR died. In univariable analysis, anemia [HR, 1.72 (95%CI: 1.11-2.66), P = 0.02], IDA [2.44 (1.48-4.01), P anemia with mortality became weaker after adjustment for ID [1.52 (0.97-2.39), P = 0.07] and disappeared after adjustment for proteinuria and eGFR [1.09 (0.67-1.78), P = 0.73]. The association of IDA with mortality attenuated after adjustment for potential confounders. In contrast, the association of ID with mortality remained independent of potential confounders, including anemia [1.77 (1.13-2.78), P = 0.01]. In conclusion, ID is highly prevalent among RTR and is associated with an increased risk of mortality, independent of anemia. As ID is a modifiable factor, correction of ID could be a target to improve survival. © 2016 The Authors.

    Alterations in energy metabolism could trigger weight gain after renal transplantation. Nineteen transplanted non-diabetic men, 53 ± 1.6 years old, receiving calcineurin inhibitors but no corticosteroids were studied. They were compared with nine healthy men matched for height, age and lean body mass. Daily energy expenditure and its components (sleeping, basal and absorptive metabolic rates) were analyzed for 24 h in calorimetric chambers and for 4 days in free living conditions using calibrated accelerometry. Other variables known to influence energy expenditure were assessed: body composition, physical activity, 4-day food intake, drug consumption, serum C-reactive protein, interleukin-6, thyroid and parathyroid hormones, and epinephrine. Transplant recipients who gained more than 5% body weight after transplantation (n = 11, +11.0 ± 1.5 kg) were compared with those who did not (n = 8) and with the controls. Weight gain compared with non-weight gain patients and controls exhibited higher fat mass without change in lean body mass. Daily, sleeping and resting energy expenditure adjusted for lean body mass was significantly higher in non-weight gain (167.1 ± 4.2 kJ/kg/lean body mass/24 h, P controls (146.1 ± 4.6). Weight gain compared with controls and non-weight gain subjects had lower free living physical activity and a higher consumption of antihypertensive drugs and β-blockers. After kidney transplantation, weight gain patients were characterized by lower adjusted energy expenditure, reduced spontaneous physical activity but a more sedentary life style and a trend toward a higher energy intake explaining the reason they gained weight. The nWG KTR had increased resting and sleeping EE which protected them from weight gain. Such hypermetabolism was also observed in 24-h EE measurements. By comparison with the nWG patients, the WG transplant recipients were characterized by higher β-blocker consumption. These data could be helpful in the prevention of weight

    Fibrosis is commonly described in heart allografts lost late after transplantation. CMR-derived ECV is a validated measure of DMF in native adult hearts that may predict heart failure and mortality. We explored associations of ECV with histologic myocardial fibrosis and clinical features after pediatric heart transplantation. Twenty-five recipients (7.0±6.3 years at transplant and 10.7±6.5 years post-transplant) were prospectively recruited for CMR and BNP measurement at the time of surveillance biopsy. All had normal ejection fractions and lacked heart failure symptoms. Fibrosis was quantified on biopsy after picrosirius red staining as CVF. ECV was quantified using contemporaneous hematocrit on basal and mid-short-axis slices. ECV was moderately correlated with CVF (r=.47; P=.019). We found no associations of ECV with hemodynamics, ischemic time, time since transplantation, or number of prior biopsies or acute rejections. Compared to healthy non-transplant controls, there was no significant difference in ECV (25.1±3.0 vs 23.7±2.0%, P=.09). Log-transformed BNP was correlated with ECV (recipients: r=.46, P=.02; recipients and controls: r=.45, P=.006). These findings suggest ECV quantifies DMF and relates to biological indicators of cardiac function after pediatric heart transplantation. © 2017 John Wiley & Sons A/S.

    Full Text Available Bacterial infections are major complications after Hematopoietic Stem Cell Transplant (HSCT. They consist mainly of bloodstream infections (BSI, followed by pneumonia and gastrointestinal infections, including typhlitis and Clostridium difficile infection. Microbiological data come mostly from BSI. Coagulase negative staphylococci and Enterobacteriaceae are the most frequent pathogens causing approximately 25% of BSI each, followed by enterococci, P. aeruginosa and viridans streptococci. Bacterial pneumonia is frequent after HSCT, and Gram-negatives are predominant. Clostridium difficile infection affects approximately 15% of HSCT recipients, being more frequent in case of allogeneic than autologous HSCT. The epidemiology and the prevalence of resistant strains vary significantly between transplant centres. In some regions, multi-drug resistant Gram-negative rods are increasingly frequent. In others, vancomycin-resistant enterococci are predominant. In the era of an increasing resistance to antibiotics, the efficacy of fluoroquinolone prophylaxis and standard treatment of febrile neutropenia have been questioned. Therefore, thorough evaluation of local epidemiology is mandatory in order to decide the need for prophylaxis and the choice of the best regimen for empirical treatment of febrile neutropenia. For the latter, individualised approach has been proposed, consisting of either escalation or de-escalation strategy. De-escalation strategy is recommended is resistant bacteria should be covered upfront, mainly in patients with severe clinical presentation and previous infection or colonisation with a resistant pathogens. Non-pharmacological interventions, such as screening for resistant bacteria, applying isolation and contact precautions should be put in place in order to limit the spread of MDR bacteria. Antimicrobial stewardship program should be implemented in transplant centres.

    This study assessed the causes and related factors of rehospitalization following renal transplantation among elderly compared with younger patients. We reviewed the charts of 567 patients rehospitalized after kidney transplantation from 2000 to 2006. According to age at the time of transplantation, hospitalizations were divided into two groups: group 1 (age >or=50 years) and group II (age 20 to 50 years). Demographics, clinical findings, causes for rehospitalization, patient outcomes (recovery, graft loss, death), intensive care unit (ICU) admission, length of hospital stay, time interval from transplantation to rehospitalization, as well as hospital costs were compared between the two groups. One hundred eighty-five (32.6%) rehospitalizations were charted for group I, who showed a higher proportion of admissions due to infection (42.2% vs 29.8%, P=.004) and macrovascular disease (3.8% vs 1.0%, P=.027) compared with group II. ICU admission (8.8% vs 2.4%, P=.001), mortality (10.2% vs 3.6%, P=.008), and hospital charges (1610 +/- 933 vs 931 +/- 850 purchase power parity dollars, P=.001) were also seen more frequently in group I but displayed a lower frequency of admissions due to graft rejection (20% vs 34.3%, P=.001). Recipient age at the time of transplantation was a main factor affecting rehospitalization among our patients.

    Limited data are available on the performance of different automated extraction platforms and commercially available quantitative real-time PCR (QRT-PCR) methods for the quantitation of cytomegalovirus (CMV) DNA in plasma. We compared the performance characteristics of the Abbott mSample preparation system DNA kit on the m24 SP instrument (Abbott), the High Pure viral nucleic acid kit on the COBAS AmpliPrep system (Roche), and the EZ1 Virus 2.0 kit on the BioRobot EZ1 extraction platform (Qiagen) coupled with the Abbott CMV PCR kit, the LightCycler CMV Quant kit (Roche), and the Q-CMV complete kit (Nanogen), for both plasma specimens from allogeneic stem cell transplant (Allo-SCT) recipients (n = 42) and the OptiQuant CMV DNA panel (AcroMetrix). The EZ1 system displayed the highest extraction efficiency over a wide range of CMV plasma DNA loads, followed by the m24 and the AmpliPrep methods. The Nanogen PCR assay yielded higher mean CMV plasma DNA values than the Abbott and the Roche PCR assays, regardless of the platform used for DNA extraction. Overall, the effects of the extraction method and the QRT-PCR used on CMV plasma DNA load measurements were less pronounced for specimens with high CMV DNA content (>10,000 copies/ml). The performance characteristics of the extraction methods and QRT-PCR assays evaluated herein for clinical samples were extensible at cell-based standards from AcroMetrix. In conclusion, different automated systems are not equally efficient for CMV DNA extraction from plasma specimens, and the plasma CMV DNA loads measured by commercially available QRT-PCRs can differ significantly. The above findings should be taken into consideration for the establishment of cutoff values for the initiation or cessation of preemptive antiviral therapies and for the interpretation of data from clinical studies in the Allo-SCT setting.

    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.

    Clostridium difficile infection (CDI) is a considerable health issue in the United States and represents the most common healthcare-associated infection. Solid organ transplant recipients are at increased risk of CDI, which can affect both graft and patient survival. However, little is known about the impact of CDI on health services utilization posttransplantation. We examined hospital-onset CDI from 2012 to 2014 among transplant recipients in the University HealthSystem Consortium, which includes academic medical center-affiliated hospitals in the United States. Infection was five times more common among transplant recipients than among general medicine inpatients (209 vs 40 per 10 000 discharges), and factors associated with CDI among transplant recipients included transplant type, risk of mortality, comorbidities, and inpatient complications. Institutional risk-standardized CDI varied more than 3-fold across high-volume hospitals (infection ratio 0.54-1.82, median 1.04, interquartile range 0.78-1.28). CDI was associated with increased 30-day readmission, transplant organ complications, cytomegalovirus infection, inpatient costs, and lengths of stay. Total observed inpatient days and direct costs for those with CDI were substantially higher than risk-standardized expected values (40 094 vs 22 843 days, costs $198 728 368 vs $154 020 528). Further efforts to detect, prevent, and manage CDI among solid organ transplant recipients are warranted. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Graft failure related to acute and chronic rejection remains an important problem in transplantation. An association has been reported between microchimerism and the development of tolerance. Since it has been established that cells of fetal origin can be found in maternal tissues long after parturition, and cells of maternal origin may persist for years in offspring, we hypothesized that this fetal-maternal microchimerism may confer tolerance and thus less graft loss for kidneys transplanted between mothers and their offspring. We used data from the Scientific Registry of Transplant Recipients to compare death-censored graft survival among recipients of living-related renal transplants sharing at least one human leukocyte antigen (HLA) haplotype with their donor. A total of 23,064 such transplants were reported from 1995 to 2004. A Cox proportional hazards model was constructed to compare death-censored graft survival among the following donor-recipient pairings: child-to-mother, child-to-father, mother-to-child, father-to-child, 1-haplotype matched siblings, and HLA-identical siblings. HLA-identical sibling recipients had the best survival, but results for the child-to-father group were not significantly worse (hazard ratio=1.07, P=0.47). Mother-to-child transplants had the poorest graft survival (hazard ratio=2.61, P<0.0001). We found no evidence of tolerance to kidneys transplanted between mothers and offspring. Our analysis of 1-haplotype matched living-related renal transplants argues against tolerance to organs based on fetal-maternal microchimerism. Mechanistic studies examining the relationship between chimerism and immune sensitization would be useful to explore our results, and may contribute to a better understanding of tolerance.

    Full Text Available Background. Quality of life (QoL is an important criterion for the treatment effi cacy that provides an important data regarding patient’s personal estimation of social adaptation and ability to perform daily duties.Methods. The study was aimed to evaluate QoL in cardiac transplant recipients. We have enrolled 42 stage D heart failure patients aged 29–61 (mean 39,23 ± 12,31 y/o, 38 males and 4 females, survived cardiac transplant surgery between Jan 2008 and Jan 2013. QoL was evaluated using the SF-36 survey prior to the heart surgery and during the follow-up period up to the 5 years.Results. Pre-operative assessment revealed low QoL indices of physical activity as well as general health status. Follow-up showed dramatic improvement in all QoL measures during 1 year after the surgery which was consistent through the whole observation period. There was an increase in physical functioning index by 2,8 times (p < 0,01, physical status dependent role functioning by 14 times (р < 0,0001, emotional status dependent role functioning by 3 times (р = 0,02, social functioning by 4,8 times (p = 0,002, pain threshold by 3 times (p = 0,02, psychic health by 3,6 times (p = 0,001, life activity by 2,6 times(p = 0,003, and total health by 1,6 times (p = 0,03. Physical activity was restored in 90% of patients during the fi rst year.Conclusion. The study shows signifi cant improvement in all QoL variables after heart transplantation in stage D heart failure patients. Main indices of physical, psychical, and social activities rise at the fi rst year and remain high during the 5-year period. These data support heart transplantation as a radical and effective method of terminal heart failure treatment.

  6. Disruption of transitional stages in 24-h blood pressure in renal transplant recipients

    Full Text Available Patients with kidney replacement exhibit disrupted circadian rhythms. Most studies measuring blood pressure use the dipper/non-dipper classification, which does not consider analysis of transitional stages between low and high blood pressure, confidence intervals nor shifts in the time of peak, while assuming subjective onsets of night and day phases. In order to better understand the nature of daily variation of blood pressure in these patients, we analyzed 24h recordings from 41 renal transplant recipients using the non-symmetrical double-logistic fitting assessment which does not assume abruptness nor symmetry in ascending and descending stages of the blood pressure profile, and a cosine best-fitting regression method (Cosinor. Compared with matched controls, double-logistic fitting showed that the times for most of transitional stages (ascending systolic and descending systolic, diastolic and mean arterial pressure had a wider distribution along the 24 h. The proportion of individuals without daily blood pressure rhythm in the transplanted group was larger only for systolic arterial pressure, and the amplitude showed no significant difference. Furthermore, the transplant recipient group had a less pronounced slope in descending systolic and ascending mean blood pressure. Cosinor analysis confirmed the phase related changes, showing a wider distribution of times of peak (acrophases. We conclude that daily disruptions in renal transplant recipients can be explained not only by absence in diurnal variation, but also in changes in waveform-related parameters of the rhythm, and that distortions in the phase of the rhythm are the most consistent finding for the patients.

    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.

    Achieving optimum outcomes after liver transplantation requires an understanding of the interaction between donor, graft and recipient factors. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes and benefit the overall waiting list by minimizing graft failure and need for re-transplantation. A PubMed search was conducted to identify published literature investigating the effects of donor factors such as age, gender, ethnicity, viral serology; graft factors such as size and quality, recipient factors such as age, size, gender and transplant factors such as major or minor blood group incompatibility and immunological factors. We also report technical and therapeutic modifications that can be used to manage donor-recipient mismatch identified from literature and the authors' clinical experience. Multiple donor and recipient factors impact graft survival after liver transplantation. Appropriate matching based on donor-organ-recipient variables, modification of surgical technique and innovative peri-transplant strategies can increase the donor pool by utilizing grafts from marginal donors that are traditionally turned down.

    and life span of human AMFs is scarce. METHODS: To follow the origin and longevity of AMFs in patients with lung transplantation for more than 100 weeks, we obtained transbronchial biopsies from 10 gender-mismatched patients with lung transplantation. These were subjected to combined in situ hybridisation...... transplantation we found that recipient monocytes seeded the alveoli early after transplantation, and showed subsequent phenotypical changes consistent with differentiation into proliferating mature AMFs. This resulted in a stable mixed chimerism between donor and recipient AMFs throughout the 2-year period...

    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.

    Full Text Available BACKGROUND: Orthotopic liver transplantation (OLT includes the implantation of partial or complete liver graft from a living or deceased donor into the recipient. The purpose of this study is to analyze health associated quality of life among OLT recipients. METHODS: This study was conducted at a tertiary care center from January 2011 to January 2015. The quality of life questionnaire was completed before OLT and 6 months after OLT by 32 patients. RESULTS: Mean age of liver transplant recipients was 45±11 years, body mass index (BMI was 24.2±4.2 kg/m2 and 28/32 (87.5% patients were males. Good health was reported by 96.9% after OLT in contrast to 81.2% patients before OLT (p=0.0001. Vigorous exercise capability was 40.6% after OLT in contrast to 28.1% before OLT (P=0.43. CONCLUSION: We found a significant increase in quality of life scores among patients who underwent OLT. However, compared to pre-OLT, recipient’s participation in vigorous activities did not change 6 months after OLT.

    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.

    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.

    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.

    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.

    Kidney transplantation offers better outcomes compared to dialysis, but requires patients to adhere to an ongoing and complex self-management regimen. Medication nonadherence remains a leading cause of transplant loss, and inadequate self-management undermines transplantation and other health outcomes. We aimed to describe kidney transplant recipients' motivations, challenges, and attitudes toward self-management. Systematic review and thematic synthesis of qualitative studies. Kidney transplant recipients. MEDLINE, EMBASE, PsycINFO, and CINAHL were searched to October 2014. Thematic synthesis. 50 studies involving 1,238 recipients aged 18 to 82 years across 19 countries were included. We identified 5 themes: empowerment through autonomy (achieving mastery, tracking against tangible targets, developing bodily intuition, routinizing and problem solving, and adaptive coping), prevailing fear of consequences (inescapable rejection anxiety, aversion to dialysis, minimizing future morbidity, trivialization and denial, and defining acceptable risks), burdensome treatment and responsibilities (frustrating ambiguities, inadvertent forgetfulness, intrusive side effects, reversing ingrained behaviors, and financial hardship), overmedicalizing life (dominating focus, evading patienthood, and succumbing to burnout), and social accountability and motivation (demonstrating gratitude toward medical team, indebtedness to donor, and peer learning). Non-English articles were excluded. Self-efficacy and social accountability are motivators for self-management, although adherence can be mentally and physically taxing. Multicomponent interventions incorporating personalized care planning, education, psychosocial support, decision aids, and self-monitoring tools may foster self-management capacity and improve transplantation outcomes.

    Self-care behaviors are crucial for following the complex regimen after lung transplantation, yet little is known about recipients' levels of self-care agency (the capability and willingness to engage in self-care behaviors) and its correlates. We examined levels of self-care agency and recipient characteristics (socio-demographics, psychological distress, quality of relationship with primary lay caregiver, and health locus of control) in 111 recipients. Based on Perceived Self-Care Agency scores, recipients were assigned to either the low- or high-self-care agency comparison group. Characteristics were compared between groups to identify characteristics likely to be associated with lower-self-care agency. Mean (SD) score for self-care agency (scale range, 53-265) was 223.02 (22.46). Recipients with lowest-self-care agency scores reported significantly poorer quality of caregiver relationships (p recipient-caregiver relationship remained significantly associated with self-care agency. Every one-point decrease in the quality of caregiver relationship increased the risk of low-self-care agency by 12%. Recipients with poorer caregiver relationships and greater psychological distress may need additional support to perform the self-care behaviors expected after lung transplantation. © 2012 John Wiley & Sons A/S.

    Full Text Available Background. De novo and donor-derived invasive fungal infections (IFIs contribute to morbidity and mortality in solid organ transplant (SOT recipients. Reporting of donor-derived IFIs (DDIFIs to the Organ Procurement Transplant Network has been mandated since 2005. Prior to that time no systematic monitoring of DDIFIs occurred in the United States. Case Presentation. We report a case of primary graft dysfunction in a 49-year-old male lung transplant recipient with diffuse patchy bilateral infiltrates likely related to pulmonary Sporothrix schenckii infection. The organism was isolated from a bronchoalveolar lavage on the second day after transplantation. Clinical and radiographic responses occurred after initiation of amphotericin B lipid formulation. Conclusion. We believe that this was likely a donor-derived infection given the early timing of the Sporothrix isolation after transplant in a bilateral single lung transplant recipient. This is the first case report of sporotrichosis in a lung transplant recipient. Our patient responded well to amphotericin induction therapy followed by maintenance therapy with itraconazole. The implications of donor-derived fungal infections and Sporothrix in transplant recipients are reviewed. Early recognition and management of these fungi are essential in improving outcomes.

    Although many human inflammatory and autoimmune diseases were previously considered to be mediated by T helper type 1 (Th1) cells, the recently described Th17 cells play dominant roles in several of these diseases. We and others speculated that allograft rejection after organ transplantation may also involve Th17 cells. Episodes of acute rejection occur in 30% of liver transplants. This study aimed to determine the frequency of circulating Th17 cells in patients who had received liver transplants for benign end-stage liver disease and to identify any association between acute rejection episodes and levels of Th17 cells in the peripheral blood. A prospective study compared Th17 cells from 76 consecutive benign end-stage liver disease patients who had undergone orthotopic liver transplantation from 2007 to 2011 with those from 20 age-matched healthy individuals. Peripheral blood samples were collected at different time points within one year after transplant. Blood samples and liver biopsies were also collected at the diagnosis of acute rejection. Percentages of circulating CD4+IL-17+ cells were measured by flow cytometry. The transplant patients were classified into two groups: a rejection group consisting of 17 patients who had an episode of acute rejection, and a non-rejection group comprising the remaining 59 patients with no acute rejection episodes. Percentages of circulating Th17 cells were compared between the two groups and controls. The levels of circulating CD4+IL-17+ T cells in the rejection group were higher during acute rejection than those in the non-rejection group (2.56+/-0.43% versus 1.79+/-0.44%, Pblood was positively correlated with the rejection activity index (r=0.79, P=0.0002). Circulating Th17 cells may be useful as a surrogate marker for predicting acute rejection in liver transplant recipients.

    Renal transplantation is associated with reduction in the risk for myocardial infarction (MI) in patients with chronic kidney disease requiring long-term dialysis (stage 5D CKD). Whether outcomes of MI differ among renal transplant recipients vs patients with stage 5D CKD or those without CKD has not been well examined. To compare in-hospital reperfusion rates and outcomes of ST-segment elevation MI (STEMI) in renal transplant recipients vs the stage 5D CKD group or the non-CKD group. The National Inpatient Sample database was queried to identify patients 18 years or older who were hospitalized with the principal diagnosis of STEMI. All hospitalizations for STEMI in the United States from January 1, 2003, to December 31, 2013, were included. Codes from International Classification of Diseases, Ninth Revision, Clinical Modification, were used to identify patients in the non-CKD, stage 5D CKD, or prior renal transplant groups. Data were analyzed from March to May 2016. In-hospital mortality. From 2003 to 2013, 2 319 002 patients in the non-CKD group (34.7% women; 65.3% men; mean [SD] age, 64.2 [14.4] years), 30 072 patients in the stage 5D CKD group (45.0% women; 55.0% men; mean [SD] age, 66.9 [12.5] years), and 2980 patients in the renal transplant group (27.3% women; 72.7% men; mean [SD] age, 57.5 [11.1] years) were identified who were hospitalized with STEMI. Of these, 68.9% of the patients in the non-CKD group, 39.5% in the stage 5D CKD group, and 65.2% in the renal transplant group received in-hospital reperfusion for STEMI. The renal transplant group was more likely to receive reperfusion compared with the stage 5D CKD group (adjusted odds ratio [AOR], 1.83; 95% CI, 1.67-2.01; P group (AOR, 0.75; 95% CI, 0.68-0.83; P group with STEMI was markedly lower compared with the stage 5D CKD group (AOR, 0.37; 95% CI, 0.33-0.43; P group (AOR, 1.14; 95% CI, 0.99-1.31; P = .08).

    Acute rejection in cardiac transplant patients remains a contributory factor to limited survival of implanted hearts. Currently, there are no biomarkers in clinical use that can predict, at the time of transplantation, the likelihood of post-transplant acute cellular rejection. Such a development would be of great value in personalizing immunosuppressive treatment. Recipient age, donor age, cold ischemic time, warm ischemic time, panel-reactive antibody, gender mismatch, blood type mismatch and human leukocyte antigens (HLA-A, -B and -DR) mismatch between recipients and donors were tested in 53 heart transplant patients for their power to predict post-transplant acute cellular rejection. Donor transplant biopsy and recipient pre-transplant blood were also examined for the presence of genomic biomarkers in 7 rejection and 11 non-rejection patients, using non-targeted data mining techniques. The biomarker based on the 8 clinical variables had an area under the receiver operating characteristic curve (AUC) of 0.53. The pre-transplant recipient blood gene-based panel did not yield better performance, but the donor heart tissue gene-based panel had an AUC = 0.78. A combination of 25 probe sets from the transplant donor biopsy and 18 probe sets from the pre-transplant recipient whole blood had an AUC = 0.90. Biologic pathways implicated include VEGF- and EGFR-signaling, and MAPK. Based on this study, the best predictive biomarker panel contains genes from recipient whole blood and donor myocardial tissue. This panel provides clinically relevant prediction power and, if validated, may personalize immunosuppressive treatment and rejection monitoring.

    The shortage of deceased donors led to an increase of living donor kidney (LDK) transplantations performed in the presence of donor-specific antibodies (DSA) or ABO incompatibility (ABOi) using various desensitization protocols. We herein analyzed 26 ABOi and 8 Luminex positive DSA patients who were successfully desensitized by anti-CD20, antigen-specific immunoadsorption and/or plasmapheresis to receive an LDK transplant. Twenty LDK recipients with non-donor-specific HLA-antibodies (low risk) and 32 without anti-HLA antibodies (no risk) served as control groups. 1-year graft survival rate and renal function was similar in all 4 groups (creatinine: 1.63 ± 0.5 vs 1.78 ± 0.6 vs 1.64 ± 0.5 vs 1.6 ± 0.3 mg/dl in ABOi, DSA, low risk and no risk group). The incidence of acute T-cell mediated rejections did not differ between the 4 groups (15% vs 12, 5% vs 15% vs 22% in ABOi, DSA, low risk and no risk), while antibody-mediated rejections were only found in the DSA (25%) and ABOi (7.5%) groups. Incidence of BK nephropathy (BKVN) was significantly more frequent after desensitization as compared to controls (5/34 vs 0/52, p = 0.03). We demonstrate favorable short-term allograft outcome in LDK transplant recipients after desensitization. However, the desensitization was associated with an increased risk of BKVN.

    Full Text Available Background/Aims: Post-transplant hypertension is highly prevalent in renal transplant recipients and is a risk factor for graft loss, cardiovascular disease and death. Glucocorticoid is used to prevent rejection, but simultaneously increases the risk of post-transplant hypertension. The glucocorticoid-induced transcript 1 (GLCCI1 promoter polymorphism (rs37972 has been reported to be associated with response to glucocorticoid therapy in asthma. We therefore examined the association between GLCCI1 promoter polymorphism and post-transplant hypertension in renal transplant recipients. Methods: We conducted a retrospective cohort study of renal transplantation at a single university hospital from October 2003 to January 2014. Fifty consecutive adult recipients were analyzed, with clinical data retrieved from a prospectively collected database. Genotyping was carried out using genomic DNA derived from recipient’s blood. GLCCI1 immunoreactivity in vascular endothelial cells was quantitatively analyzed by immunohistochemical staining of recipients’ native kidney biopsy-specimens. The primary outcome measure was post-transplant hypertension. Results: Post-transplant hypertension was observed in 14/17 (82% of recipients with CC, 18/20 (90% with CT, and 2/13 (15% with TT genotype. CC/CT genotype was significantly associated with post-transplant hypertension, even after adjustment for covariates (odds ratio, 10.6; 95% confidence intervals, 1.32 to 85.8; P = 0.026. In addition, we observed that GLCCI1 immunoreactivity in arteriolar endothelial cells was higher in kidney specimens obtained from recipients with a CC/CT genotype than a TT genotype (P = 0.021. Conclusion: GLCCI1 promoter polymorphism rs37972 may be associated with post-transplant hypertension.

    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.

    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.

    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 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.

    Full Text Available Background: Kidney transplant recipients need self-management during their lifetime, and training these patients is essential for the realization of self-management. Teach-back training (TBT was used to receive, understand, and retain information. This study aimed to determine the effect of TBT on self-management in kidney transplant recipients. Methods: In this clinical trial study, 84 kidney transplant recipients who referred to the clinic of Imam Khomeini Hospital in Urmia (a city in northwest of Iran, from January to March 2017, were selected through convenience sampling and randomly assigned to intervention and control groups. In the intervention group, educational content was presented for each patient with TBT in 5 sessions of 60 minutes. Data were collected before and after the intervention by a special Self-Management Questionnaire for Kidney Transplant Recipients in five areas as follows: self-monitoring, self-care behavior in daily living, early detecting and coping with abnormalities after kidney transplantation, stress management and the category of non-categorized area. This is a valid and reliable questionnaire (α=0.76. Collected data were analyzed by independent t-test and Mann-Whitney test. Statistical analysis was performed using SPSS 20 and P≤0.05 was considered as significant. Results: Independent t-test showed that the mean of self-management score between the control and intervention groups was not statistically significant before the intervention (P=0.90. The mean score of self-management increased after implementation of TBT in the intervention group compared to the control group, and the difference was statistically significant (P=0.001. Conclusion: The implementation of TBT method is effective in promoting self-management of kidney transplant recipients. Therefore, it is recommended that this method should be used to train the patients to better understand the components of self-management. Trial Registration Number

    2016-10-01

    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.

    BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics are the most commonly used drugs and are increasingly available over-the-counter (OTC). In certain groups of patients, including kidney transplant recipients, their use may be complicated by adverse effects or drug interactions. The aim of our study was to assess the causes and frequency of OTC NSAIDs or analgesics use, as well as the awareness of related side effects. MATERIAL AND METHODS We enrolled 94 randomly selected kidney transplant recipients, who represented 5% of all kidney transplant recipients at our center. An anonymous survey consisting of 23 multiple-choice questions was administered voluntarily and anonymously. RESULTS In all, 63% of study patients confirmed taking the OTC painkillers; 22% of these patients took these drugs at least several times a week, and 4% took these drugs daily. For 38% of the study kidney transplant recipients, NSAIDs or analgesics were reported to be the only way to manage their pain. In addition, 30% of study patients were unaware of the risks associated with these drugs, despite the fact that 89% of the study patients consider physicians the best source of information. CONCLUSIONS Our study found that 63% of kidney transplant recipients regularly took OTC painkillers and 30% were unaware of the potential adverse effects. This necessitates continuous, ongoing education of kidney transplant recipients about the risks of OTC NSAIDs or analgesics use.

    Kidney transplant outcomes that vary by program or geopolitical unit may result from variability in practice patterns or health care delivery systems. In this collaborative study, we compared kidney graft outcomes among 4 countries (United States, United Kingdom, Australia, and New Zealand) on 3 continents. We analyzed transplant and follow-up registry data from 1988-2014 for 379 257 recipients of first kidney-only transplants using Cox regression. Compared to the United States, 1-year adjusted graft failure risk was significantly higher in the United Kingdom (hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.18-1.26, P < .001) and New Zealand (hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.14-1.46, P < .001), but lower in Australia (HR 0.90, 95% CI 0.84-0.96, P = .001). In contrast, long-term adjusted graft failure risk (conditional on 1-year function) was significantly higher in the United States compared to Australia, New Zealand, and the United Kingdom (HR 0.74, 0.75, and 0.74, respectively; each P < .001). Thus long-term kidney graft outcomes are approximately 25% worse in the United States than in 3 other countries with well-developed kidney transplant systems. Case mix differences and residual confounding from unmeasured factors were found to be unlikely explanations. These findings suggest that identification of potentially modifiable country-specific differences in care delivery and/or practice patterns should be sought. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Laminar air flow isolation and decontamination procedures were evaluated in a prospective randomized study in patients with aplastic anemia or acute leukemia undergoing marrow transplantation from HLA-matched siblings. Patients transplanted in the laminar air flow group had significantly less septicemia and major local infections than did patients in the control group. Nineteen of 46 laminar air flow patients and six of 44 control patients are alive at present. In patients with aplastic anemia the survival was 13 of 17 in the laminar air flow group compared with four of 17 in the control group. In patients with acute leukemia the survival was six of 29 in the laminar air flow group versus two of 27 in the control group. These differences were not statistically significant. Death in both the laminar air flow and control groups was predominantly due to interstitial pneumonitis or recurrent leukemia, which were unaffected by isolation and decontamination

    Bacterial infections remain a challenge to solid organ transplantation. Due to the alarming spread of carbapenem-resistant gram negative bacteria, these organisms have been frequently recognized as cause of severe infections in solid organ transplant recipients. Between 15 May and 30 September 2012 we enrolled 887 solid organ transplant recipients in Italy with the aim to describe the epidemiology of gram negative bacteria spreading, to explore potential risk factors and to assess the effect of early isolation of gram negative bacteria on recipients' mortality during the first 90 days after transplantation. During the study period 185 clinical isolates of gram negative bacteria were reported, for an incidence of 2.39 per 1000 recipient-days. Positive cultures for gram negative bacteria occurred early after transplantation (median time 26 days; incidence rate 4.33, 1.67 and 1.14 per 1,000 recipient-days in the first, second and third month after SOT, respectively). Forty-nine of these clinical isolates were due to carbapenem-resistant gram negative bacteria (26.5%; incidence 0.63 per 1000 recipient-days). Carbapenems resistance was particularly frequent among Klebsiella spp. isolates (49.1%). Recipients with longer hospital stay and those who received either heart or lung graft were at the highest risk of testing positive for any gram negative bacteria. Moreover recipients with longer hospital stay, lung recipients and those admitted to hospital for more than 48h before transplantation had the highest probability to have culture(s) positive for carbapenem-resistant gram negative bacteria. Forty-four organ recipients died (0.57 per 1000 recipient-days) during the study period. Recipients with at least one positive culture for carbapenem-resistant gram negative bacteria had a 10.23-fold higher mortality rate than those who did not. The isolation of gram-negative bacteria is most frequent among recipient with hospital stays >48 hours prior to transplant and in those

    Full Text Available Type I diabetes (T1D, mediated by autoreactive T cell destruction of insulin-producing islet beta cells, has been treated with bone marrow-derived hematopoietic stem cell (BM-HSC transplantation. Older non-obese diabetic (NOD mice recipients (3m, at disease-onset stage receiving syngeneic BM-HSC progressed more rapidly to end-stage diabetes post-transplantation than younger recipients (4-6w, at disease-initiation stage. FACS analyses showed a higher percentage and absolute number of regulatory T cells (Treg and lower proportion of proliferating T conventional cells (Tcon in pancreatic lymph nodes from the resistant mice among the younger recipients compared to the rapid progressors among the older recipients. Treg distribution in spleen, mesenteric lymph nodes (MLN, blood and thymus between the two groups was similar. However, the percentage of thymic Tcon and the proliferation of Tcon in MLN and blood were lower in the young resistants. These results suggest recipient age and associated disease stage as a variable to consider in BM-HSC transplantation for treating T1D.

    We evaluated late intensive care unit admission in liver transplant recipients to identify incidences and causes of acute respiratory failure in the postoperative period and to compare these results with results in patients who did not have acute respiratory failure. We retrospectively screened the data of 173 consecutive adult liver transplant recipients from January 2005 through March 2015 to identify patients with late admission (> 30 d posttransplant) to an intensive care unit. Patients were divided into 2 groups: patients with and without acute respiratory failure. Acute respiratory failure was defined as severe dyspnea, respiratory distress, decreased oxygen saturation, hypoxemia or hypercapnia on room air, or need for noninvasive or invasive mechanical ventilation. Demographic, laboratory, clinical, and respiratory data were collected. Model for End-Stage Liver Disease, Acute Physiology and Chronic Health Evaluation II, and Sequential Organ Failure Assessment scores; lengths of intensive care unit and hospital stays; and hospital mortality were assessed. Among 173 patients, 37 (21.4%) were admitted to an intensive care unit, including 22 (59.5%) with acute respiratory failure. The leading cause of acute respiratory failure was pneumonia (n = 19, 86.4%). Patients with acute respiratory failure had significantly lower levels of albumin before intensive care unit admission (P = .003). In patients with acute respiratory failure, severe sepsis and septic shock were more frequently observed and tracheotomy was more frequently performed (P = .041). Acute respiratory failure developed in 59.5% of liver transplant recipients with late intensive care unit admission. The leading cause was pneumonia, with this group of patients having higher requirements for invasive mechanical ventilation and tracheotomy, longer stays in an intensive care unit, and higher mortality.

    Claudia Rosso Felipe

    Full Text Available Abstract Cytomegalovirus (CMV infection in kidney transplantation has changed its clinical spectrum, mostly due to the current and more effective immunosuppression. In the absence of preventive strategies it is associated with significant morbi-mortality. Objective: This study evaluated the incidence of CMV events and its effect on outcomes of kidney transplantation in recipients without pharmacological prophylaxis or targeted preemptive treatment. Results: The study cohort comprised 802 recipients of kidney transplants between 04/30/2014 and 04/30/2015. The majority received induction with anti-thymocyte globulin (81.5%, tacrolimus and prednisone in combination with either mycophenolate (46.3% or azathioprine (53.7%. The overall incidence of CMV events was 42% (58.6% infection and 41.4% disease. Patients with CMV showed higher incidence of first treated acute rejection (19 vs. 11%, p = 0,001 compared with those without CMV but no differences in graft loss, death or loss to follow-up. The incidence of delayed graft function was higher (56% vs. 37%, p = 0.000 and the eGFR at 1 (41 ± 21 vs. 54 ± 28 ml/min, p = 0.000 and 12 months (50 ± 19 vs. 61 ± 29 ml/min, p = 0.000 were lower in patients with CMV. Recipients age (OR = 1.03, negative CMV serology (OR = 5.21 and use of mycophenolate (OR = 1.67 were associated with increased risk of CMV. Changes in immunosuppression was more often in patients with CMV (63% vs. 31%, p = 0.000. Conclusion: the incidence of CMV events was high and associated with higher incidence of acute rejection and changes in immunosuppression. Besides traditional risk factors, renal function at 1 month was independently associated with CMV infection.

    Background and objectives: Billing claims are increasingly examined beyond administrative functions as outcomes measures in observational research. 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

    Despite advances in islet transplantation, challenges remain in monitoring for anti-islet immune responses. Soluble CD30 (sCD30) has been investigated as a predictor of acute rejection in kidney, lung, and heart transplantation as well as in a single study in human islet cell recipients. In this study, sCD30 levels were retrospectively assessed in 19 allograft recipients treated with three different immunosuppression induction therapies. Soluble CD30 levels were assessed at pre-transplant; early post-transplant (day 4-day 7); one-month post-transplant; and late post-transplant (day 90-day 120) and then correlated with eventual graft outcomes at 1-year follow-up. Results showed no correlation between mean serum sCD30 levels at any point in time pre- or post-transplant and graft function at 1-year follow-up. However, analysis demonstrated that mean sCD30 levels at day 28 or day 90-day 120 decreased from pre-transplant levels in recipients with long-term islet allograft function compared to recipients with partial or non-graft function (a decrease of 43.6+/-25.6% compared to 16.7+/-35.2%, psCD30 levels post-transplant overall. A larger reduction post-transplant correlated with full graft function. The results demonstrate that a relative reduction in sCD30 levels post-transplant may be applicable as a biomarker to monitor graft function in islet allograft recipients. Additionally, knowledge of the impact of various immunosuppression protocols on the timing and extent of changes in post-transplant sCD30 levels could aid in patient-specific tailoring of immunosuppression.

    The adipokine progranulin has metabolic proprieties, playing a role in obesity and insulin resistance. Its levels seems to be dependent of renal function, since higher progranulin concentration is observed in patients with end-stage kidney disease. However, the effect of kidney transplantation on progranulin remains unknown. To assess the serum progranulin levels in kidney transplant recipients before and after kidney transplantation. Forty-six prospective kidney transplant recipients were included in this longitudinal study. They were evaluated before transplantation and at three and twelve months after transplantation. Clinical, anthropometric and laboratorial measurements were assessed. Progranulin was determined with enzyme-linked immunosorbent assays. Serum progranulin significantly decreased in the early period after transplantation (from 72.78 ± 2.86 ng/mL before transplantation to 40.65 ± 1.49 ng/mL at three months; pProgranulin was associated with waist circumference and fasting plasma glucose after adjusted for age, gender, study period, glomerular filtration rate, interleukin-6, high sensitivity C reactive protein and adiponectin. Progranulin serum levels are increased before transplantation and a reduction is observed in the early period after transplantation, possibly attributed to an improvement in renal function. At one year after transplantation, an increment in progranulin is observed, seems to be independent of glomerular filtration, and remained significantly lower than before transplantation.

    AIM: To investigate whether a lessened glucocorticoid cumulative dose would lead to a decreased incidence of femoral head osteonecrosis. METHODS: Newly transplanted in-patients (n=49) underwent hip radiographs and magnetic resonance imaging (MRI) a mean of 17.0±4.3 (range 8-29) days after renal transplantation. For the 48 patients without evidence of prevalent osteonecrosis, imaging at a mean of 5.9±0.8 (range 4.8-8.7) months after renal transplantation was graded for presence/absence of femoral head osteonecrosis by two blinded radiologists. Sociodemographic and disease characteristics of patients were compared to identify potential associations with incident osteonecrosis. RESULTS: At 6-month follow-up, only two patients (4%) had osteonecrosis of the femoral head (three hips). The two primary radiologists had excellent agreement between osteonecrosis diagnosis (kappa coefficient=0.78). Both cases of a definite MRI diagnosis of osteonecrosis occurred in patients who were in the highest tertile of glucocorticoid dosage. CONCLUSION: Osteonecrosis was uncommon among a prospective cohort of renal transplant recipients within 6 months after engraftment

    Conclusion: Although the number of cases of tuberculosis is low, its post-transplant frequency is significant and the observed mortality rate is not to be neglected. The cases of hepatotoxicity and graft rejection seen in this case series demonstrate the challenges associated with tuberculosis diagnosis in liver transplant recipients and management of the interactions between immunosuppressors and rifampin. This study strengthens the recommendation of latent tuberculosis infection screening and treatment in liver transplant candidates or recipients.

    The diagnosis of invasive aspergillosis remains challenging in solid organ transplants in general, and in lung transplant recipients, in particular, because of colonization. Lung transplant recipients may be over treated with antifungal drugs because of the lack of appropriate diagnostic tools. A review of the new developments of diagnostic tools and whether this help distinguishing colonization from invasive disease is presented. Efforts are being made to develop new tools that will allow us to identify which patients will develop IPA, and those who will be able to control the disease.

    Insulin-dependent diabetic recipients of successful pancreas allografts achieve self-regulatory insulin secretion and discontinue exogenous insulin therapy; however, chronic hyperinsulinemia and impaired insulin sensitivity generally develop. To determine whether insulin resistance is accompanied...... by altered signal transduction, skeletal muscle biopsies were obtained from pancreas-kidney transplant recipients (n = 4), nondiabetic kidney transplant recipients (receiving the same immunosuppressive drugs; n = 5), and healthy subjects (n = 6) before and during a euglycemic-hyperinsulinemic clamp. Basal...... insulin receptor substrate (IRS)-1 Ser (312) and Ser (616) phosphorylation, IRS-1-associated phosphatidylinositol 3-kinase activity, and extracellular signal-regulated kinase (ERK)-1/2 phosphorylation were elevated in pancreas-kidney transplant recipients, coincident with fasting hyperinsulinemia.

    Cytomegalovirus (CMV) is the most common viral infection following kidney transplant, has been recognized as a major factor for graft loss and increased incidence of acute rejection. Different studies have reported a variable incidence of CMV disease with the use of Mycophenolate mofetil (MMF). We retrospectively analyzed our renal transplant recipients to review the results of CMV disease and to compare CMV disease in patient on Azathioprine and MMF for this purpose we retrospectively reviewed 521 live related kidney transplant recipients at our institute. 74 (14.2 %) live related allograft recipients developed CMV disease after a median interval of 7.18 ± 4.35 months from transplantation. The mean age was 36.15 ± 10.7 years. 63 of the patients were male. Malaise, fever and diarrhea were among most common symptoms. 20 (27.02 %) of the 74 recipients developed transaminitis, 13 (17.2 %) developed CMV gastritis, 5 (9.13 %) recipients developed pneumonia, and 3 (4.05 %) patient developed colitis. 59 (80 %) patients had leucopenia and 41 (56.5 %) developed thrombocytopenia. Mean serum creatinine level was 1.5 ± 0.4 (0.9-2.4) mg/dl before the disease, 1.9 ± 0.6 (1.3-3.6) mg/dl at the time of the diagnosis, and 1.7 ± 0.06 (0.8-4.2) mg/dl at the end of the treatment. CMV disease developed in 9 (36 %) of recipients who received basiliximab as induction therapy and 13 (30.24 %) of recipients who received ATG (p > 0.05). The incidence of CMV disease was similar in cyclosporine based regimen (13.2 %) and Tacrolimus based regimen 27 (16.16 %) (p = 0.137) and was also similar in Azathioprine 41 (9.5 %) and MMF group 33 (14.3 %) (p = 0.163). There was no significant difference in severity of CMV disease in both groups, except a higher incidence of leucopenia in Azathioprine group (86 vs. 74 %, p < 0.05) as compared to MMF group. 51 (68.91 %) patient developed graft dysfunction during CMV disease. In conclusion we report a low incidence

    In this study, peripheral blood lymphocytes were compared between a brand-name and a generic tacrolimus group in stable liver transplant recipients. Sixteen patients who underwent ABO-compatible living donor liver transplants between 2012 and 2013 and had stable graft function were included in this study. Ten patients received brand-name tacrolimus and 6 patients received generic tacrolimus. CD3, CD4, CD8, γδ, CD4+FoxP3+, and CD3-CD56+ T cells were analyzed in peripheral blood obtained preoperatively and 4, 8, 12, and 24 weeks after liver transplantation. Categorical variables were compared using a χ2 test or Fisher exact test, and continuous variables were compared using the Mann-Whitney U test. Regarding the baseline and perioperative characteristics, there were no statistically significant differences between the 2 groups. Immunosuppression also was not different. Subtype analysis of T-cell populations carried out in parallel showed similar levels of CD3, CD4, CD8, and γδT cells with brand-name tacrolimus and generic tacrolimus in stable liver transplant recipients. However, the levels of CD4+Foxp3+ and CD3-CD56+ T cells were higher in the brand-name tacrolimus group than in the generic tacrolimus group 8 weeks after transplantation (p brand-name tacrolimus group than in the generic tacrolimus group after transplantation. This finding showed that brand-name tacrolimus could have more potential immunosuppressive activity than generic tacrolimus regarding the contribution of CD4+Foxp3+ T cells to graft tolerance in liver transplant recipients. © 2017 S.

    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.

    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.

    Recipients of kidney transplantation have elevated risk of developing cancer. There are limited data on cancer risk in recipients of kidney retransplantation. We used data from the Transplant Cancer Match Study, which links the U.S. transplant registry with 15 cancer registries. Cancer incidence in recipients of kidney retransplantation and primary kidney transplants was compared utilizing Poisson regression, adjusting for demographic and medical characteristics. We assessed 109 224 primary recipients and 6621 retransplants. Compared to primary recipients, retransplants were younger (median age 40 vs. 46 yr), had higher PRA, and more often received induction with polyclonal antibodies (43% vs. 25%). A total of 5757 cancers were observed in primary recipients and 245 in retransplants. Overall cancer risk was similar in retransplants compared with primary recipients (incidence rate ratio [IRR] 1.06, 95% CI 0.93-1.20, adjusted for age, gender, race/ethnicity, PRA, and use of polyclonal induction). However, renal cell carcinoma (RCC) occurred in excess among retransplants (adjusted IRR 2.03, 95% CI 1.45-2.77), based on 514 cases in primary recipients and 43 cases in retransplants. Overall cancer risk did not differ in retransplants compared to primary recipients. Increased risk of RCC may be explained by the presence of acquired cystic kidney disease, which is more likely to develop with additional time with kidney disease and time spent on dialysis waiting for retransplantation. © 2015 John Wiley & Sons A/S.

    To determine the factors related to immunosuppressant therapy adherence in kidney transplant recipients in Taiwan. Adherence to immunosuppressant treatment is critical after kidney transplantation. Thus, the factors associated with self-reported medication adherence in kidney transplant recipients warrant investigation. The study used a cross-sectional and correlation design. A convenience sample of 145 kidney transplant recipients was included. Structured questionnaires were used to collect data during 2012-2013. Multivariate linear regression was used to examine the factors related to immunosuppressant therapy adherence. Over half of the participants were female (54·5%), mean age was 45·5 years, and mean year after transplant was 7·4. The mean score for medication adherence was 29·73 (possible score range 7-35). The results of the multivariate linear regression analysis showed that gender (male), low income with a high school or college education, years after transplantation and concerns about medication taking were negatively associated with adherence. Medication self-efficacy was positively associated with adherence. Therapy-related factors, partnerships with healthcare professionals and having private healthcare insurance did not significantly relate to immunosuppressant therapy adherence. Kidney transplant recipients demonstrated a high level of adherence. Strategies to enhance patients' self-efficacy and alleviate concerns about medication may promote medication adherence. Male patients, those with a lower income and those with a higher education level, should be a focus of efforts to maintain adherence to the medication regimen. © 2016 John Wiley & Sons Ltd.

    The frequency of B19 infection in renal transplant donors and recipients was studied to determine the significance of active viral infection in the development of anemia. Serum, plasma, and peripheral blood leukocyte samples of 47 renal transplant donors, 38 recipients with anemia (Group 1), and 25 without anemia (Group 2) after renal transplantation were evaluated for the presence of anti-B19 specific antibodies (ELISA) and B19 DNA (nPCR). Active persistent B19 infection after renal transplantation was detected in 12 of the 38 in the Group 1 (10 had reactivation and 2 primary infection), and none of the recipients in the Group 2 had it. Of the 12 recipients in the Group 1, 10 were seropositive and 2 seronegative before renal transplantation; 10 received the transplants from the seropositive and 2 from seronegative donors. rHuEPO therapy-resistant severe anemia was detected only in the recipients with active B19 infection after renal transplantation in the Group 1 (7/12). The logistic regression analysis revealed a significant relationship between active B19 infection and severe anemia (OR, 0.039; 95% CI, 0.006-0.257; P=0.001). Active B19 infection was documented only in the anemic recipients and could be associated with the development of severe anemia after renal transplantation. This allows us to recommend concurrent screening for viral DNA in plasma and detection of anti-B19 IgM class antibodies. To find the association between B19 infection and the development of anemia, further investigations are necessary.

    Kidney transplantation is the gold standard for patients with end-stage kidney disease. In view of shortages of available organs, long wait times for possible transplantation, and strict regulation, many patients opt for commercial transplantation. This study elicits the reasons and motivations for patients with end-stage kidney disease to elect for commercial transplant. A questionnaire-based evaluation was conducted during the period from July 2015 until late December 2015. It consisted of 29 multiple choice questions and was distributed to all patients who underwent commercial kidney transplantation. One hundred and fifty patients were approached to participate and 106 agreed. Of the participants, 60% were male with an average age of 41.5 (SD 14.8) years and ranged from 18 to 83 years. The majority (82%) of our participants were educated ranging from primary to college level. The major reason (71%) for these participants to obtain commercial transplants was stated as the unavailability of a live related donor. Thirteen percent stated that they objected to getting a kidney donated from a family member, and 9% stated that they were worried about taking a kidney from a family member. Finally, 3% of participants stated that they needed prompt transplant and could not wait for a long time for transplant investigations and the workup associated with this program. The study showed that the most common underlying cause for seeking commercial transplantation is the unavailability of a national transplant program, particularly transplantation from deceased sources. All western ethical arguments turn out to become of vital importance in developing countries, because transplantation is the cheapest renal replacement therapy. However, it must be emphasized that commercial transplants should not be an alternative to building a national transplant initiative. The national diseased program must be a priority with full financial and administrative support. All government

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

    Full Text Available Pharmacists may play a key role on the multidisciplinary transplant team. This article describes the development and current status of pharmacists in the management of transplant recipients in the United States. Traditionally, pharmacists played an important support role in transplant medicine. This role has been expanded to include direct patient care for the avoidance, detection, and/or treatment of side effects from the polypharmacy necessary in the management of these complex patients. Pharmacists provide pre- and post-transplant education to transplant recipients to enhance adherence to complicated medical regimens and thereby reduce readmission to hospital and unscheduled, costly visits to urgent care centers and/or hospital emergency departments.

    Patients with short telomere syndromes and pulmonary fibrosis have increased complications after lung transplant. However, the more general impact of donor and recipient telomere length in lung transplant has not been well characterized. This was an observational cohort study of patients who received lung transplant at a single center between January 1st 2012 and January 31st 2015. Relative donor lymphocyte telomere length was measured and classified into long (third tertile) and short (other tertiles). Relative recipient lung telomere length was measured and classified into short (first tertile) and long (other tertiles). Outcome data included survival, need for modification of immunosuppression, liver or kidney injury, cytomegalovirus reactivation, and acute rejection. Recipient lung tissue telomere lengths were measured for 54 of the 79 patients (68.3%) who underwent transplant during the study period. Donor lymphocyte telomeres were measured for 45 (83.3%) of these recipients. Neither long donor telomere length (hazard ratio [HR] = 0.58, 95% confidence interval [CI], 0.12-2.85, p = 0.50) nor short recipient telomere length (HR = 1.01, 95% CI = 0.50-2.05, p = 0.96) were associated with adjusted survival following lung transplant. Recipients with short telomeres were less likely to have acute cellular rejection (23.5% vs. 58.8%, p = 0.02) but were not more likely to have other organ dysfunction. In this small cohort, neither long donor lymphocyte telomeres nor short recipient lung tissue telomeres were associated with adjusted survival after lung transplantation. Larger studies are needed to confirm these findings.

    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.

    Children born to female kidney recipients are exposed to immunosuppressive drugs during gestation. Little is known about their immune system at birth or in the long term. Twenty-eight children born to female kidney recipients and 40 full-term children born to healthy mothers were evaluated. T, B, NK, NKT, γδT cells were assessed by flow cytometry and functional evaluation of T and dendritic cells after in vitro activation was performed at birth and at 8 months of age. At birth, infants born to female kidney recipients showed lower numbers of CD4+ T, NKT and intense reduction of B cells (median cells/mm(3) , transplant: 153.7 X control: 512.4; p memory and exhausted memory B cells showed higher percentages among children exposed to immunosuppressors when compared to control group. At 8 months, most immune alterations were no longer observed, but four children still had low numbers of some lymphocyte subsets at this age. Children born to female kidney recipients had 4.351 (95% CI: 1.026-15.225; p = 0.046) higher risk of hospital admission in the first months of life-some, with severe clinical manifestations-than those born to healthy women. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    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.

    Pregnancy and parenting have been part of human life throughout history and liver transplant recipients are not any exception. This paper reports successful pregnancies in two liver transplant recipients in Iran. The first case was a 34-year old woman who had undergone orthotopic liver transplantation (OLT) at Shiraz Namazi Educational Hospital in 2002. She decided to get pregnant seven years after the operation. During pregnancy, immunosuppressive therapy continued, except Mycophenolate Mofetil which has an absolute contra-indication in pregnancy. The patient was followed up during pregnancy by the transplant team as well as a gynecologist. She faced no significant complications and the liver function was stable during pregnancy. She later underwent a Cesarean section in the 38(th) week of gestation and the newborn was a healthy girl weighing 2480g with an Apgar score of 8 at the time of birth. There were no evidences of prematurity or structural abnormalities in the newborn. The second case was a 31-year old primipara who had received an orthotopic liver transplant (OLT) in Shiraz in 2002. She had a smooth pregnancy without any complications and the newborn was a boy weighing 3100g with Apgar scores of 8 and 10 at the time of birth and 5 minutes thereafter, respectively. As the number of transplant recipients is growing along with the number of recipients who are in their fertility years, it is vital to ensure a proper medical care by a coordinated multidisciplinary team during pregnancy.

    To describe how registered nurse work motivation, attitudes, subjective norm and perceived behavioural control influence intention to promote physical activity in hospitalised adult liver transplant recipients. Descriptive study of clinical registered nurses caring for recipients of liver transplant at a tertiary medical centre. Intent to Mobilise Liver Transplant Recipient Scale, Work Extrinsic and Intrinsic Motivation Scale, and demographics were used to explore registered nurses' work motivation, attitudes, subjective norms, perceived behavioural control and intention to promote physical activity of hospitalised adult liver transplant recipients during the acute postoperative phase. Data analysis included demographics, comparison between scale items and analysis of factors predicting intent to mobilise. Factors predictive of intention to promote physical activity after liver transplant included appropriate knowledge to mobilise patients (R 2  = .40) and identification of physical activity as nursing staff priority (R 2  = .15) and responsibility (R 2  = .03). When implementing an early mobilisation protocol after the liver transplant, education on effects of physical activity in the immediate postoperative period are essential to promote implementation in practice. Nursing care environment and leadership must be supportive to ensure mobility is a registered nurse priority and responsibility. Nursing managers can leverage results to implement a mobility protocol. © 2017 John Wiley & Sons Ltd.

    During the 1990s, gram-positive bacteria emerged as major pathogens after liver transplantation. We sought to determine whether the pathogens associated with bacteremias in liver transplant recipients have changed. Patients included 233 liver transplant recipients transplanted between 1989 and 2003. The proportion of all infections due to bacteremias increased significantly over time (P gram-negatives increased from 25% in the period of 1989-1993 to 51.8% in 1998-03, that of gram-positive bacteria decreased from 75% in the period of 1989-93 to 48.2% in the period of 1998-2003. Methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most frequent pathogens in bacteremic patients. The incidence of bacteremias due to MRSA and Pseudomonas aeruginosa has remained unchanged (P gram-negative bacteria, particularly Klebsiella pneumoniae has increased (P =.02). Klebsiella pneumoniae isolates in the current quartile were not clonally related. In conclusion, bacteremias as a proportion of all infections in liver transplant recipients have increased significantly over time, due in part to a decline in infections due to other major pathogens, e.g., fungi, primarily Candida species, and CMV. Gram-negative bacteria have emerged as predominant pathogens in bacteremic liver transplant recipients.

    Organ transplantation is a psychosocially demanding process. Patients must undergo a comprehensive evaluation to await a donor organ that may never become available. After transplantation, recipients must deal with the acceptance of a new organ and comply with a medical regimen that includes numerous medications, follow-up exams, and procedures. Emotional well-being is monitored throughout the transplant process. However, despite the best of efforts and thorough pretransplant bio-psycho-social evaluations, it is possible for patients to have significant psychopathology that remains undetected. Following the stress of transplantation, such patients may present with exacerbation of symptomatology, which has the potential to negatively affect compliance and long-term outcome.

    The success of a pediatric kidney transplantation program can only be judged by reviewing its results. We aim to audit our short-term outcome of pediatric kidney transplantation at the King Fahad Specialist Hospital-Dammam. A retrospective chart review was performed to collect data about recipient demographics, etiology of end-stage kidney disease, type of dialysis, type of donor and outcome. Between September 2008 and April 2012, 35 pediatric kidney trans-plantations (need to encourage preemptive transplantation and living donation in this population.

    We report the first case of a pregnancy in a renal transplant recipient with HIV infection. She underwent renal transplantation in 2005 and became pregnant in 2009. The patient underwent vaginal delivery and a healthy full-term, female baby was born. Almost 6 years after delivery, both mother and child were doing well. The management of concurrent renal transplantation, HIV infection and pregnancy was extremely challenging. Women with HIV infection who have undergone renal transplantation should be accurately informed of the potential health risks for them and their offspring. Multidisciplinary teams are mandatory in order to properly manage these patients.

    BACKGROUND Nonmelanoma skin cancer is the most common form of cancer in humans and also the malignant disease that is increasingly common among kidney transplant recipients. OBJECTIVE To determine the epidemiological characteristics of renal transplant recipients with nonmelanoma skin cancer seen at a referral transplantation center. METHODS Cross-sectional descriptive study with renal transplant recipients presenting nonmelanoma skin cancer, treated at a transplantation referral center between 08/01/2004 and 08/31/2009. Analyzed variables were: gender, age, skin phototype, occupational and recreational sun exposure, use of photoprotection, personal and family history of non-melanoma skin cancer, clinical type and location, time between transplantation and the appearance of the first nonmelanoma skin cancer, occurrence of viral warts, timing of transplantation, type of donor, cause of kidney failure, previous transplants, comorbidities, pre-transplant dialysis, type and duration of dialysis. RESULTS 64 subjects were included. Males - 71.9%; low skin phototypes (up to Fitzpatrick III) - 89%; mean age - 57.0 years - and mean age at transplant - 47.3 years; sun exposure - 67.2% occupational - and 64.1% recreational; photoprotection - 78.2% (although only 34.4% in a regular manner); squamous cell carcinoma - 67.2%; squamous cell carcinoma/basal cell carcinoma ratio - 2:1; personal history of nonmelanoma skin cancer - 25% - and family history - 10.9%; location at photoexposed area - 98.4%; average latency time between transplantation and first nonmelanoma skin cancer appearance - 78.3 months; viral warts (HPV) after transplant - 53.1%; average timing of transplantation - 115.5 months; living donor - 64.1%; triple regimen (antirejection) - 73.2%; comorbidities - 92.2%; pre-transplant dialysis - 98.4%; hemodialysis - 71.7%; average duration of dialysis - 39.1 months; previous transplants - 3.1%; hypertension as cause of renal failure - 46.9%.

    The objective is to present the causes of late death in patients subjected to liver transplantation. A total of 209 patients were subjected to 223 liver transplantations (14 retransplantations). The computerized study protocol sheets were evaluated to determine the causes of late death (> 6 months after transplantation). Of the 209 patients, 30 had late death. Ductopenic rejection (chronic rejection) was the most common cause and it was observed in 10 patients. Time after transplantation at the moment of death of this group of patients varied from 11 to 57 months, with an average of 29 months. Seven patients died at the hospital admission of hepatic retransplantation. Other causes of late death were sepsis, lymphoproliferative disease, chronic renal insufficiency, and hepatic insufficiency. The most common cause of late death after liver transplantation is ductopenic rejection, followed by complications of retransplantation and sepsis. Death owing to ductopenic rejection may occur even many years after transplantation.

    To describe HLA antigen distribution, looking for possible markers of renal disease in Mapuche and non-Mapuche people in the renal transplantation program, we reviewed data from 1297 histocompatibility studies of the Chilean national renal transplantation program (421 donors and 876 recipients), performed between 2000 and 2005. Mapuche people were classified according to their family surnames. The most frequent antigens found among the total Chilean population were A2 (48%), A19 (33%), B16 (33%), B35 (26%), DR4 (38%), and DR6 (28%), without significant differences between donors and recipients. Among the 114 individuals (9%) classified as Mapuche, the most frequent antigens were A28 (49%), A2 (44%), B16 (63%), B35 (24%), DR4 (48%), and DR8 (30%), with A28/B16/DR4 as the most common haplotype. In contrast, A28, B16, DR4, and DR8 were significantly more frequent in Mapuche compared with non-Mapuche people. B8 was significantly more frequent in Mapuche recipients than in non-Mapuche recipients and Mapuche donors. The higher frequency of some HLA antigens in Mapuche people was confirmed, possibly corresponding to ethnic markers. The special concentration of B8 among Mapuche recipients might represent a genetic factor predisposing to chronic renal disease in this human group.

    Gastroesophageal reflux (GER) and aspiration of bile acids have been implicated as non-alloimmune risk factors for the development of bronchiolitis obliterans syndrome (BOS) after lung transplantation. The aim of our study was to investigate the association between GER and gastric aspiration of bile acids and to establish which reflux characteristics may promote aspiration of bile acids into the lungs and may feature as a potential diagnostic tool in identifying lung transplantation (LTx) patients at risk for aspiration. Twenty-four stable LTx recipients were studied 1 year after transplantation. All patients underwent 24-hour ambulatory impedance-pH recording for the detection of acid (pH acidic (pH 4 to 7) reflux. On the same day, bronchoalveolar lavage fluid (BALF) was collected and then analyzed for the presence of bile acids (Bioquant enzymatic assay). Increased GER was detected in 13 patients, of whom 9 had increased acid reflux and 4 had exclusively increased weakly acidic reflux. Sixteen patients had detectable bile acids in the BALF (0.6 [0.4 to 1.5] micromol/liter). The 24-hour esophageal volume exposure was significantly increased in patients with bile acids compared to patients without bile acids in the BALF. Acid exposure and the number of reflux events (total, acid and weakly acidic) were unrelated to the presence of bile acids in the BALF. However, both nocturnal volume exposure and the number of nocturnal weakly acidic reflux events were significantly higher in patients with bile acids in the BALF. Weakly acidic reflux events, especially during the night, are associated with the aspiration of bile acids in LTx recipients and may therefore feature as a potential risk factor for the development of BOS.

    Background There is little information on the role of bisphosphonates and bone mineral density (BMD) measurements for the follow-up and management of bone loss and fractures in long-term kidney transplant recipients. Methods To address this question, we retrospectively studied 554 patients who had two BMD measurements after the first year posttransplant and compared outcomes in patients treated, or not with bisphosphonates between the two BMD assessments. Kaplan-Meier survival and stepwise Cox regression analyses were performed to examine fracture-free survival rates and the risk-factors associated with fractures. Results The average time (±SE) between transplant and the first BMD was 1.2±0.05 years. The time interval between the two BMD measurements was 2.5±0.05 years. There were 239 and 315 patients in the no-bisphosphonate and bisphosphonate groups, respectively. Treatment was associated with significant preservation of bone loss at the femoral neck (HR 1.56, 95% CI 1.21-2.06, P=0.0007). However, there was no association between bone loss at the femoral neck and fractures regardless of bisphosphonate therapy. Stepwise Cox regression analyses showed that type-1 diabetes, baseline femoral neck T-score, interleukin-2 receptor blockade, and proteinuria (HR 2.02, 0.69, 0.4, 1.23 respectively, Pbone loss in long-term kidney transplant recipients. However, these data suggest a limited role for the initiation of therapy after the first posttransplant year to prevent fractures. PMID:18645484

    Graft failure due to chronic rejection is greater among renal transplant patients with donor-specific antibody (DSA) than among DSA-free patients. For patients dependent on deceased donor transplantation, preoperative desensitization to eliminate DSAs may be impractical. We speculated that perioperative desensitization might eliminate preexisting DSAs and prevent de novo DSAs and improve graft outcomes. We report that brief perioperative desensitization using either intravenous immunoglobulin (IVIG) or plasmapheresis/IVIG (PP/IVIG) treatment improves clinical outcomes among patients with positive crossmatches. Immediately following deceased donor transplantation, 235 renal recipients were assigned points for PRA and flow crossmatches (FCXM): delayed graft function (DGF) ≤ 1 point received standard therapy; 2 points received high-dose IVIG; and ≥3 points received PP/IVIG. The DSAs were serially monitored by single antigen bead luminex for 1 year. Five-year clinical outcomes were determined from the chart review. All desensitized patients had preoperatively positive FCXM with DSA. Rejection was more common (P desensitized than nonsensitized groups. However, overall graft survivals were similar between the groups (P = not significant) and superior to historic untreated patients (P 90% in all desensitizated patients with DSA elimination as well as PP/IVIG patients with residual DSA. In contrast, IVIG patients with persistent DSA had poorer graft survival (45%, P desensitization improved overall graft survival of sensitized patients compared to historic untreated patients. Plasmapheresis/IVIG had greater impact on DSA eradication and graft survival than IVIG alone. © 2016, NATCO.

    End-stage renal disease (ESRD) is more common among Blacks, but Blacks are less likely to receive a live donor kidney transplant (LDKT). The objective of this study is to identify barriers and coping mechanisms that Black LDKT recipients and donors experienced while receiving or donating a kidney. A qualitative study was conducted using structured interviews. Thematic analysis was used for data interpretation. All 20 participants identified as Black, with two participants identifying themselves as multiracial. The mean age for the 14 recipients was 60, and the average age for the 6 living donors was 47. Themes emerging from the data suggest both recipients and donors faced barriers in the LDKT experience. Recipients faced barriers associated with their denial and avoidance of the severity of their ESRD, their desire to maintain the privacy of their health status, and their refusal to approach potential donors. Donors encountered negative responses from others about the donors' desire to donate and the initial refusal of recipients to accept a LDKT offer. Recipients identified faith as a coping mechanism, while donors identified normalization of donation as their method of coping. Various types of social support helped donors and recipients navigate the transplant process. Black LDKT recipients and donors must overcome barriers prior to receiving or donating a kidney. Most of these barriers arise from communication and interactions with others that are either lacking or undesirable. Future interventions to promote LDKT among Blacks may benefit by specifically targeting these barriers.

    Full Text Available Introduction. Proteinuria after renal transplantation increases the risk of graft failure and mortality. The aim of the study was to determine the prevalence and causes of proteinuria in kidney transplant recipients. Methods. All kidney transplant recipients followed up in our clinic were included in the study. As a center protocol 24-hour urine collections were used to quantify protein excretion with 3-month intervals posttransplantation during the first year, and yearly thereafter. The etiology of chronic kidney disease and demographic characteristics of the study group were obtained from outpatient records. Data regarding the immunosuppressive regimens used, 24-hour proteinuria levels and creatinine clearences, new-onset hypertension, new-onset diabetes mellitus, rejection episodes, infections like cytomegalovirus (CMV and polyoma (BK, and biopsy findings were noted. Results. A total of 260 kidney transplant recipients (97 females, mean age 42.3±12.3 years were evaluated. Median follow-up period was 36 months; 137 of all transplantations were from living donors. Mean age of donors was 42.7±15 years and 133 were female. Proteinuria with protein excretion ≥300 mg/d was present in 35.4% of patients. The most common cause of biopsy-proven proteinuria was transplant-specific conditions (acute rejection, and borderline changes. Conclusion. The prevalence of proteinuria was 35.4%. The transplant-specific diagnoses were the most likely causes. Even in nonnephrotic ranges it was associated with decreased graft survival.

    Objective: To assess short-term outcomes after lung transplantation with organs procured following brain death. Methods: Between April 2015 and July 2016, all 17 recipients after lung transplantation using organs from brain death donors (DBD) at Department of Thoracic Surgery, Shanghai Pulmonary Hospital, Tongji University School of Medicine were enrolled in this study. All patients were male, aging (60±7) years, including 11 chronic obstructive pulmonary disease, 5 idiopathic pulmonary fibrosis, 1 silicosis. Seventeen donors were 16 males and 1 female, with 10 traumatic brain injury, 5 cerebrovascular accident and 2 sudden cardiac death. Of 17 recipients receiving DBD lung transplant, 16 were single lung transplant. Data were collected including intubation duration of mechanical ventilation, hospital length of stay, incidence of pulmonary infection bronchus anastomosis complications, primary graft dysfunction (PGD), and acute rejection, bronchiolitis obliterans syndrome (BOS) as well as mortality of 90-day after lung transplantation. Results: Median duration of intubation were 2 (2) days ( M ( Q R )) in recipients after lung transplantation. The incidence of pulmonary infection and bronchus anastomosis complications were 15/17 and 5/17, respectively. Median length of stay in hospital were 56 (19) days. The ratio of readmission 1 month after discharge were 10/17. Mortality of 90-day post-transplant were 2/17. The incidence of PGD and BOS were 1/17 and 2/17, respectively. Conclusion: Recipients with DBD lung transplantation have an acceptable survival during short-term follow-up, but with higher incidences of complications related to infection post-transplantation.

    Parvovirus B19 is a DNA virus that is responsible for causing several diseases in humans. Parvovirus B19-induced persistent anemia is one of its manifestations that is relatively common in transplant recipients. This study was aimed to investigate the seroprevalence of parvovirus B19 among kidney transplant recipients. Ninety-one transplant recipients were selected randomly and were investigated for several variables including age, gender, educational status, history of hemodialysis (HD), history of blood transfusion and immunosuppressive therapy. Two milliliters of blood samples were collected via venipuncture and evaluated for anti-Parvovirus B19 IgG antibody using enzyme-linked immunosorbent assay. All recipients were anemic, with 72.5% of them suffering from severe anemia (Hb ≤ 11 in men and ≤ 10 in women). Sixty-three patients (69.2%) were seropositive for Parvovirus B19. There was no significant difference in age, sex, educational status, history of blood transfusion, history of HD and immunosuppressive therapy between seropositive and seronegative groups. The seroprevalence of Parvovirus B19 was relatively high in kidney transplant recipients in Urmia, Iran. Our study failed to find a correlation between the severity of anemia and the seropositivity of Parvovirus B19.

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

    Full Text Available Colchicine is a relatively safe medication that is widely used for both prevention and treatment of gout attack. However, serious adverse events, including myoneuropathy and multiorgan failure, have been reported. We report a case of colchicine-induced myoneuropathy in a female kidney transplant recipient who had been taking cyclosporine. She developed gastrointestinal discomfort and paresthesia 5 days after the initiation of colchicine. She showed signs of myoneuropathy, and hepatic and renal injury. Colchicine toxicity was suspected, and colchicine was discontinued. Her symptoms and laboratory findings improved gradually. Literature was reviewed for previous reports of colchicine-induced myoneuropathy in solid organ transplant recipients.

  17. Genitourinary tuberculosis - a rare presentation of a still frequent infection in renal transplant recipients

    Directory of Open Access Journals (Sweden)

    Natacha Jardim Rodrigues

    Full Text Available Abstract Mycobacterium tuberculosis infection in renal transplant recipients is associated with significant morbidity and mortality. Genitourinary tuberculosis is a less frequent presentation and a high level of suspicion is needed to avoid treatment delay. Management is challenging due to the interaction of calcineurin inhibitors with antituberculous medications and the known side effects of these drugs, with higher prevalence in this population. The authors present a case of a renal transplant recipient with urinary and constitutional symptoms whom is diagnosed with tuberculosis after a prostatic biopsy in an already disseminated stage and develops hepatotoxicity to antituberculous therapy.

    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).

    2015-01-01

    Full Text Available Fournier′s gangrene is not a common cause of morbidity in renal transplant recipients, but, if it occurs, it is difficult to treat because of the immunosuppression and associated increased mortality rate. We describe the case of a male patient who underwent renal transplantation with complicated post-operative course, resulting in cecum perforation (thermal injury due to cautery use during transplantation requiring exploratory laparotomy and cecostomy. A few days later, he developed Fournier′s gangrene and urgent radical surgical debridement of the scrotum was performed, along with aggressive antibiotic regimen and the immunosuppressive treatment was modified. Subsequently, the patient underwent scheduled cecostomy closure (right hemicolectomy, while the scrotum trauma healed with tertiary intention. Epidemiologic characteristics, clinical presentation, diagnostic workup, therapeutic options and morbidity-mortality rates of Fournier′s gangrene are reviewed, emphasizing the role of immunosuppression in renal transplant recipients to disease development.

    We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus. Despite ureteral tortuosity, laser stone fragmentation succeeded. The calculus was completely removed with an antegrade guidewire. Mild postoperative ureteral stenosis resolved with a temporary ureteral stent without balloon dilation. Ureterolithotripsy is effective even in renal transplant recipients with ureteroureterostomy.

    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.

    Although over the past decade the management of invasive fungal infection has improved, considerable controversy persists regarding antifungal prophylaxis in solid organ transplant recipients. To identify the key clinical knowledge and make by consensus the high level recommendations required for antifungal prophylaxis in solid organ transplant recipients. Spanish prospective questionnaire, which measures consensus through the Delphi technique, was conducted anonymously and by e-mail with 30 national multidisciplinary experts, specialists in invasive fungal infections from six national scientific societies, including intensivists, anesthetists, microbiologists, pharmacologists and specialists in infectious diseases that responded to 12 questions prepared by the coordination group, after an exhaustive review of the literature in the last few years. The level of agreement achieved among experts in each of the categories should be equal to or greater than 70% in order to make a clinical recommendation. In a second term, after extracting the recommendations of the selected topics, a face-to-face meeting was held with more than 60 specialists who were asked to validate the pre-selected recommendations and derived algorithm. Echinocandin antifungal prophylaxis should be considered in liver transplant with major risk factors (retransplantation, renal failure requiring dialysis after transplantation, pretransplant liver failure, not early reoperation, or MELD>30); heart transplant with hemodialysis, and surgical re-exploration after transplantation; environmental colonization by Aspergillus, or cytomegalovirus (CMV) infection; and pancreas and intestinal transplant in case of acute graft rejection, hemodialysis, initial graft dysfunction, post-perfusion pancreatitis with anastomotic problems or need for laparotomy after transplantation. Antifungal fluconazole prophylaxis should be considered in liver transplant without major risk factors and MELD 20-30, split or living

    Fungal pathogens are increasingly encountered after renal transplantation. Aspergillus causes significant morbidity and mortality in transplant patients. Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may be identical with that of subacute thyroiditis, in which hyperthyroidism features and painful thyroid are the prominent findings. Diagnosis can be ascertained by fine-needle aspiration of thyroid showing branching hyphae of Aspergillus. We describe a renal transplant patient who developed Aspergillus thyroiditis as part of a disseminated infection successfully treated with voriconazole. © 2010 John Wiley & Sons A/S.

    Invasive fungal diseases (IFD) are severe complications in patients receiving immunosuppression after solid organ or allogeneic stem cell transplantation. Extensive study has been conducted on therapeutic strategies for IFD in neutropenic patients, mostly those with hematological malignancy. There is an ongoing discussion on whether these studies may be applied to transplant patients as well. We have reviewed relevant literature on transplantation and clinical mycology of the last 20 years and selected articles relevant for today's treatment decisions. This article reports on the epidemiology of IFD in transplant recipients and current antifungal drugs in the context of tansplantation medicine. For invasive aspergillosis and invasive candidiasis, we give a detailed report of current clinical evidence. This review is intended as a quick-start for clinicians and other care providers new to transplant care and as an update for experienced transplant physicians. In a field in which evidence is scarce and conflicting, we provide evidence-based strategies for diagnosing and treating the most relevant IFD in transplant recipients. Physicians treating transplant patients should maintain a high level of awareness towards IFD. They should know the local epidemiology of IFD to make the optimal decision between current diagnostic and therapeutic strategies. Prophylaxis or early treatment should be considered given the high mortality of IFD.

  9. Influence of p53 (rs1625895 polymorphism in kidney transplant recipients

    2014-01-01

    Full Text Available Reperfusion injury predisposes the kidney allograft to acute rejection. Apoptosis is a mechanism that results in graft injury, and TP53 is an important involved gene. To determine the association between single nucleotide polymorphism (SNP in the pro-apoptotic protein p53 (rs1625895 and acute rejection in renal transplants, we studied 100 recipients of kidney allografts and 100 healthy individuals served as controls. The polymorphism was determined by the polymerase chain reaction restriction-fragment length polymorphism (PCR-RFLP test. Overall, 31 recipients developed rejection. There was no difference in the genotype frequencies between the recipients and the controls. However, we found a difference of genotype and allele frequencies between recipients with and those without rejection. The WW genotype was more frequent in recipients with rejection. Although rejection is a complex immunologic event and functional importance of SNPs has not been confirmed yet, we suggest that wild type p53 may promote apoptosis during inflammation.

    Full Text Available Abstract Background Portal vein thrombosis is a frequent complication in end-stage cirrhosis with a considerable peri-operative risk for liver transplant candidates. We aimed to characterize the pre-transplant portal vein thrombosis in a cohort of liver transplant recipients, and to identify independent risk factors for this complication. Methods 380 consecutive primary orthotopic liver transplants were performed in the Digestive Surgery Department of “12 de Octubre” Hospital (Madrid, Spain, between January 2001 and December 2006. The main risk factors considered were smoking, obesity, metabolic disorders, previous immobility, surgery or trauma, nephrotic syndrome, associated tumor, inflammatory disease, neoplasm myeloprolipherative. Furthermore we have reported genetic thrombophilia results for 271 recipients. Results Sixty-two (16.3% patients developed pre-transplant portal vein thrombosis and its presence had no impact in the overall survival of liver recipients. Obesity was the only independent risk factor for pre-transplant portal vein thrombosis. Conclusion We recommend close control of cardiovascular factors in patients with liver cirrhosis in order to avoid associated thrombosis.

    The purpose of this study was to review the clinical and CT findings of pulmonary nodules and masses in lung transplant recipients and to determine distinguishing features among the various aetiologies. This retrospective study included 106 lung transplant recipients who had a chest CT performed over a 7-year period in a single institution. Twenty-four cases of pulmonary nodules and masses were observed on CT. Among the single lesions, three (50 %) were due to infections, one (17 %) to organizing pneumonia, and two (33 %) remained of undetermined origin. Among the multiple lesions, 14 (78 %) were due to infection, three to post-transplant lymphoproliferative disorder (17 %), and one to bronchogenic carcinoma (5 %). The two main microorganisms were P. aeruginosa and Aspergillus spp. Among 12 solid nodules > 1 cm, four (33 %) were due to malignancy: three post-transplant lymphoproliferative disorders (25 %), and one bronchogenic carcinoma (8 %). Among five cavitary nodules four (80 %) were due to aspergillosis. Infection is the most frequent aetiology of pulmonary nodules and masses in lung transplant recipients, but other causes such as post-transplant lymphoproliferative disorder, bronchogenic carcinoma, or organizing pneumonia should be considered.

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

    Hypertension in kidney transplant recipients (KTRs) is a risk factor for cardiovascular mortality and graft loss. Data on the prevalence of hypertension and uncontrolled hypertension (uHT) in paediatric and young adult KTRs are scarce. Also, it is unknown whether 'transition' (the transfer from paediatric to adult care) influences control of hypertension. We assessed the prevalence of hypertension and uHT among Dutch paediatric and young adult KTRs and analysed the effects of transition. Additionally, we made an inventory of variations in treatment policies in Dutch transplant centres. Cross-sectional and longitudinal national data from living KTRs ≤30 years of age (≥1-year post-transplant, eGFR >20 mL/min) were extracted from the 'RICH Q' database, which comprises information about all Dutch KTRs Hypertension and uHT were more prevalent in young adult KTRs (86.4 and 75.8%) than in paediatric KTRs (62.7 and 38.3%) according to the KDIGO definition. Time after transplantation was comparable between these groups. Longitudinal analysis showed no evidence of effect of transition on systolic BP or prevalence of uHT. Policies vary considerably between and within centres on the definition of hypertension, BP measurement and antihypertensive treatment. Average BP in KTRs increases continuously with age between 6 and 30 years. Young adult KTRs have significantly more uHT than paediatric KTRs according to KDIGO guidelines. Transition does not influence the prevalence of uHT. © The Author 2016. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

    Life expectancy after pediatric renal transplantation remains lower than that of the normal population largely due to cardiovascular morbidity and mortality. Hyperlipidemia is a potentially modifiable risk factor for cardiovascular morbidity. Retrospective chart review of all available pediatric renal transplant patients (26) in a single center with assessment of anthropometry, renal function, steroid, calcineurin or mTOR inhibitor exposure and Ω3 FA supplementation. Eighteen transplant recipients without Ω3 FA supplementation served as control. Nutrition and supplement surveys were conducted with standardized questionnaires. Fasting cholesterol values were compared using the latest value prior to start of Ω3 FA and at last follow-up. Eight patients (five receiving mTOR inhibitor) started Ω3 FA supplementation at a mean dose of 29.2 ± 12 mg of EPA/kg and 16.1 ± 7.4 mg DHA/kg body weight. Median duration of treatment was 2.5 yr (range 0.8-5.9 yr) and their total fasting cholesterol at last follow-up dropped significantly from 5.08 ± 0.97 (control group 3.77 ± 0.81, p = 0.0084) to 4.17 ± 0.54 mm (p = 0.0158). High-density lipoprotein cholesterol increased not significantly from 1.74 ± 0.49 to 2.02 ± 0.93 mm. No patient had increased bleeding.

    Background The natural course of hepatic fibrosis in HCV allograft recipients with sustained virological response (SVR) after anti-HCV therapy remains debatable. The aim of this study was to examine the progression of fibrosis in a cohort of patients who achieved SVR compared with those without treatment. Methods The 167 patients who met the inclusion and exclusion criteria were chosen from a transplant database. All patients were required to have histological evidence of recurrent HCV infection post-liver transplantation and a follow-up biopsy. The 140 of these patients had received anti-viral therapy. Twenty-seven patients were identified as controls and were matched with the treatment group in all respects. The patients were categorized into four groups based on treatment response: 1) no treatment (control) (n = 27); 2) non-responders (n = 81); 3) relapsers (n = 32); and 4) SVR (n = 27). The endpoint was the stage of fibrosis on the follow-up liver biopsy. Results The treated and untreated groups were similar in clinical characteristics at the time of transplantation and prior to the initiation of treatment. The 72% of the cohort showed a fibrosis progression of ≥ 1 stage; this change did not significantly differ between the patient groups. Nonetheless, the fibrosis progression rate was the highest in the untreated group and lowest in the patients who achieved SVR. A coefficient of determination was used. Improvements in fibrosis scores were found with greater treatment duration. These improvements were most evident with the achievement of SVR. Conclusions In conclusion, SVR after anti-viral therapy for recurrent hepatitis C infection post-transplantation was associated with slower fibrosis progression and significantly improved graft survival.

    This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

    Bacteremias among renal transplant recipients are more frequent as a result of immunosuppression. They are considered extremely high-risk because they are correlated with decreased allograft and recipient survival. All episodes of bacteremia among renal transplant recipients were documented following review of medical records, from January 2010 to May 2013. In total 26 episodes of bacteremia were observed in 22 patients. Gram negative bacteremia was identified in 73% (19/26) cases. Pathogens according to their frequency were the following Escherichia coli (6/26, 23%), Klebsiella pneumonia (5/26, 19%), Pseudomonas aeruginosa (3/26, 11%), Staphylococcus epidermidis (3/26, 11%), Acinetobacter baumanni (2/26, 7.7%), Enterococcus faecalis (2/26, 7.7%). The first trimester post renal transplantation 18 episodes (69%) of bacteremia were presented that were not correlated to indwelling urinary catheter or stent. Positive urinary culture with the same pathogen was recognized in 13 patients. All recipients manifested fever, eight recipients had leucocytosis and three cases were complicated by septic shock. Immediate resuscitation with intravenous fluids and non-nephrotoxic antibiotic regimen was initiated. Acute renal allograft dysfunction (defined as an increase in serum creatinine more than 0.5 mg/dL from baseline) was observed in five patients and was restored following infection resolution. Increased prevalence of bacteremia in renal transplant recipients is attributed to immunosuppression and usually bacteremic episodes follow urinary tract infection. The commonest pathogens are Gram negative bacteria with E. coli the most frequent. Early detection and proper management are important as bacteremia affects renal allograft and recipient survival.

    Background Kidney transplant recipients, like other patients with chronic kidney disease (CKD), experience excess risk of cardiovascular disease (CVD) and elevated total homocysteine (tHcy) concentrations. Observational studies of patients with CKD suggest increased homocysteine is a risk factor for CVD. The impact of lowering total homocysteine (tHcy) levels in kidney transplant recipients is unknown. Methods and Results In a double-blind controlled trial, we randomized 4110 stable kidney transplant recipients to a multivitamin that included either a high dose (n=2056) or low dose (n=2054) of folic acid, vitamin B6, and vitamin B12 to determine whether decreasing tHcy concentrations reduced the rate of the primary composite arteriosclerotic CVD outcome (myocardial infarction, stroke, CVD death, resuscitated sudden death, coronary artery or renal artery revascularization, lower extremity arterial disease, carotid endarterectomy or angioplasty, or abdominal aortic aneurysm repair). Mean follow-up was 4.0 years. Treatment with the high dose multivitamin reduced homocysteine but did not reduce the rates of the primary outcome (n= 547 total events; hazards ratio [95% confidence interval] = 0.99 [0.84–1.17]), or secondary outcomes of all-cause mortality (n=431 deaths; 1.04 [0.86–1.26]) or dialysis-dependent kidney failure (n=343 events; 1.15 [0.93–1.43]) compared to the low dose multivitamin. Conclusions Treatment with a high dose folic acid, B6, and B12 multivitamin in kidney transplant recipients did not reduce a composite cardiovascular disease outcome, all-cause mortality, or dialysis-dependent kidney failure despite significant reduction in homocysteine level.

One of these diseases, post-transplant lymphoproliferative disease, is a major complication among organ transplant recipients. Management of this entity is problematic due to the difficulties with laboratory surveillance, diagnosis, prevention and treatment. A group of Canadian and American experts was assembled to discuss these aspects of Epstein-Barr virus diseases in Canadian organ transplant recipients. This report summarizes the relevant background literature and levels of evidence in relation to the outcomes of the deliberations and recommendations by the expert panel.

    In a randomized, open-label trial, de novo heart transplant recipients were randomized to everolimus (3-6 ng/mL) with reduced-exposure calcineurin inhibitor (CNI; cyclosporine) to weeks 7-11 after transplant, followed by increased everolimus exposure (target 6-10 ng/mL) with cyclosporine withdrawal...... events occurred in 37.3% and 19.6% of everolimus- and CNI-treated patients, respectively (p = 0.078). These results suggest that early CNI withdrawal after heart transplantation supported by everolimus, mycophenolic acid and steroids with lymphocyte-depleting induction is safe at intermediate follow...

    Lung transplantation can be a life-saving measure for people with end-stage lung disease from systemic sclerosis. However, outcomes of lung transplantation may be compromised by gastrointestinal manifestations of systemic sclerosis, which can involve any part of the gastrointestinal tract. Esophageal and gastric disease can be managed by enteral feeding with the use of a gastrojejunal feeding tube. In this report, we describe the clinical courses of 2 lung transplant recipients with systemic sclerosis who experienced severe and prolonged barium-impaction ileus after insertion of a percutaneous gastrojejunal feeding tube.

    Full Text Available ABSTRACT Objective: Respiratory infections constitute a major cause of morbidity and mortality in solid organ transplant recipients. The incidence of pulmonary tuberculosis is high among such patients. On imaging, tuberculosis has various presentations. Greater understanding of those presentations could reduce the impact of the disease by facilitating early diagnosis. Therefore, we attempted to describe the HRCT patterns of pulmonary tuberculosis in lung transplant recipients. Methods: From two hospitals in southern Brazil, we collected the following data on lung transplant recipients who developed pulmonary tuberculosis: gender; age; symptoms; the lung disease that led to transplantation; HRCT pattern; distribution of findings; time from transplantation to pulmonary tuberculosis; and mortality rate. The HRCT findings were classified as miliary nodules; cavitation and centrilobular nodules with a tree-in-bud pattern; ground-glass attenuation with consolidation; mediastinal lymph node enlargement; or pleural effusion. Results: We evaluated 402 lung transplant recipients, 19 of whom developed pulmonary tuberculosis after transplantation. Among those 19 patients, the most common HRCT patterns were ground-glass attenuation with consolidation (in 42%; cavitation and centrilobular nodules with a tree-in-bud pattern (in 31.5%; and mediastinal lymph node enlargement (in 15.7%. Among the patients with cavitation and centrilobular nodules with a tree-in-bud pattern, the distribution was within the upper lobes in 66.6%. No pleural effusion was observed. Despite treatment, one-year mortality was 47.3%. Conclusions: The predominant HRCT pattern was ground-glass attenuation with consolidation, followed by cavitation and centrilobular nodules with a tree-in-bud pattern. These findings are similar to those reported for immunocompetent patients with pulmonary tuberculosis and considerably different from those reported for AIDS patients with the same disease.

    The aim of this work was to determine the type and the significance of taste disorders in allogeneic bone marrow transplanted patients. In a retrospective study the taste threshold of a cohort of 15 allogeneic bone marrow transplanted patients, 4-51 months after transplantation (mean: 30.6 +/- 15.8), was compared to the taste threshold of 8 autologous bone marrow recipients, 4-48 months after transplantation (mean: 24.12 +/- 12.18), and to the taste threshold of a group of 20 consecutive normal subjects. Allogeneic bone marrow transplanted patients showed a significant hypogeusia for salt (Pearson's chi square p = 0.0002; Yates' correction p = 0.0007) and sour (Pearson's chi square p = 0.001; Yates' correction p = 0.008). No significant variations were observed for sweet and bitter. Autologous bone marrow recipients did not show any significant variation of taste acuity for sweet, salt or sour; a constant reduction of the taste threshold for bitter was observed, but the values were not significantly different from normal (Pearson's chi square p = 0.47; Yates' correction p = 0.83). So, late and selective taste disorders are observed in allogeneic bone marrow transplanted patients. Since the severity of the disorders is not strictly related to the severity of chronic oral G.V.H.D., taste analysis could discover the slightest, clinically undetectable cases of chronic oral G.V.H.D. The mechanism of immune aggression on the sensorial taste cells is poorly understood. Further trials are needed to define variations of taste acuity not only after allogeneic bone marrow transplantation, but also in systemic immune diseases.

    Emotional factors are generally recognized as impacting the care of end-stage heart disease and mortality following cardiac transplants. Equally important, however, are predictors of pretransplant mortality. The current study examined the utility of the Millon Behavioral Health Inventory (MBHI) as a predictor of pre- and posttransplant mortality. A total of 103 cardiac transplant candidates were assessed with the MBHI as part of a pretransplant evaluation that included baseline demographic variables and cardiac status. Time to transplant and mortality status at 1 and 5 years was also obtained. Cluster analysis of MBHI response scores elicited two clusters characterized by high and low distress. Cluster membership predicted survival status at 1-year and 5-year follow-up, with high distress cluster patients having significantly higher mortality in both the total sample and a subgroup of patients who did receive a heart transplant. These results support the value of the MBHI for assessing personality attributes that may dispose toward unfavorable outcome in heart transplant candidates. Further understanding of psychosocial contributions to illness course and outcome may enable more effective selection of treatment interventions with cardiac patients.

    Delayed graft function (DGF) and slow graft function (SGF) are a continuous spectrum of ischemia-reperfusion-related acute kidney injury (AKI) that increases the risk for acute rejection and graft loss after kidney transplantation. Regulatory T cells (Tregs) are critical in transplant tolerance and attenuate murine AKI. In this prospective observational cohort study, we evaluated whether pretransplantation peripheral blood recipient Treg frequency and suppressive function are predictors of DGF and SGF after kidney transplantation. Deceased donor kidney transplant recipients (n=53) were divided into AKI (n=37; DGF, n=10; SGF, n=27) and immediate graft function (n=16) groups. Pretransplantation peripheral blood CD4CD25FoxP3 Treg frequency was quantified by flow cytometry. Regulatory T-cell suppressive function was measured by suppression of autologous effector T-cell proliferation by Treg in co-culture. Pretransplantation Treg suppressive function, but not frequency, was decreased in AKI recipients (Paccounting for the effects of cold ischemic time and donor age, Treg suppressive function discriminated DGF from immediate graft function recipients in multinomial logistic regression (odds ratio, 0.77; Pfunction is a potential independent pretransplantation predictor of DGF and SGF.

    1998-12-01

    Since cyclosporine A (CsA) had been used in renal transplant recipients, important improvements in short-term and long-term graft survivals have been detected. In spite of these improvements CsA seems to have several adverse effects. First, CsA leads to nephrotoxicity. Moreover, CsA affects the other organs and systems (skin, liver, nervous system, etc.) and causes, increased risks of infections and malignancies. Hypomagnesemia is one of the side effects of CsA therapy, but it is a rare condition in living related donor renal transplant recipients. It may also cause multi-system dysfunction, especially hypocalcemia and hypokalemia, which cannot be corrected without magnesium therapy. In addition, rhabdomyolysis was detected in animals, but it has not been reported in living related donor renal transplant recipients. In this case report, a living related donor renal transplant recipient who suffered from hypomagnesemia and mild rhabdomyolysis due to CsA therapy will be described and discussed.

    After acute parvovirus B19 (B19V) infection of immunocompetent individuals, viral genomes persist lifelong in various tissues. In immunocompromized patients, acute B19V infection may be associated with severe anaemia. It is unclear whether reactivation of latent B19V DNA may contribute to persistent viraemia and anaemia in transplant recipients. We retrospectively analysed the impact of B19V infection in 371 adult transplant recipients (kidney, liver, heart, bone marrow). The patients' pre-transplantation serostatus was determined. 1431 sera or plasmas obtained in monthly intervals during six months following transplantation were analysed for the presence of B19V DNA by quantitative PCR which allows discrimination between B19V genotypes 1-3. Overall, 82% of the patients were seropositive. B19V DNA (<600-1100 geq/ml) was detected in 4.0% of patients and classified as genotype 1 in 12, genotype 2 in one and genotype 3 in two patients. Whereas 5.5%, 6.7% and 5.7% of liver, heart and bone marrow recipients displayed DNAemia, viral genomes were detected only in 1.4% of kidney recipients. Haemoglobin levels and reticulocyte counts showed no differences between DNAemic and non-DNAemic patients. In a control group of 120 healthy subjects, 78% were seropositive and 2.5% displayed DNAemia. Prevalence and level of B19V DNAemia in adult transplant recipients was comparable to that observed in healthy individuals, but with a distinct accumulation within the first weeks post-transplantation. The presence of low-level DNAemia in transplant recipients was not associated with anaemia. Copyright © 2013 Elsevier B.V. All rights reserved.

    2010-01-01

    It has been suggested that the serum soluble CD30 (sCD30) level may be a poten-tial marker for the prediction of acute allograft rejection in kidney transplant recipients. Therefore, its serum concentrations might offer a promising non-invasive tool to recognize patients with an increased risk for developing an acute graft rejection. We retrospectively correlate pre and post transplant level on post transplant graft survival, incidence of acute rejection and graft function using stored serum samples. Ninety-nine patients were divided in two separate groups: Group A in whom sample collection was done one day before transplantation and Group B where sample collection was done five days after transplantation. Younger recipients (aged less than 20 years) had higher sCD30 levels (P= 0.02). There was neither significant difference in the incidence of acute rejection nor incomplete response rate after anti rejection therapy in relation to pre transplant or post transplant sCD30. We could not find a significantly inferior graft survival rate in the high sCD30 group. In conclusion, younger patients had higher sCD30 concentrations however no correlation existed between the serum concentrations and occurrence of rejection episodes or graft survival.

    Transplant immunosuppressants are often used off-label because of insufficient randomized prospective trial data to achieve organ-specific US Food and Drug Administration (FDA) approval. Transplant recipients who rely on Medicare Part D for immunosuppressant drug coverage are vulnerable to coverage denial for off-label prescriptions, unless use is supported by Centers for Medicare & Medicaid Services (CMS)-approved compendia. An integrated dataset including national transplant registry data and 3 years of dispensed pharmacy records was used to identify the prevalence of immunosuppression use that is both off-label and not supported by CMS-approved compendia. Numbers of potentially vulnerable transplant recipients were identified. Off-label and off-compendia immunosuppression regimens are frequently prescribed (3-year mean: lung 66.5%, intestine 34.2%, pancreas 33.4%, heart 21.8%, liver 16.5%, kidney 0%). The annual retail cost of these at-risk medications exceeds $30 million. This population-based study of transplant immunosuppressants vulnerable to claim denials under Medicare Part D coverage demonstrates a substantial gap between clinical practice, current FDA approval processes, and policy mandates for pharmaceutical coverage. This coverage barrier reduces access to life-saving medications for patients without alternative resources and may increase the risk of graft loss and death from medication nonadherence. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

  11. Factors Associated with Postoperative Prolonged Mechanical Ventilation in Pediatric Liver Transplant Recipients

    Full Text Available Introduction. Almost all pediatric orthotopic liver transplant (OLT recipients require mechanical ventilation in the early postoperative period. Prolonged postoperative mechanical ventilation (PPMV may be a marker of severe disease and may be associated with morbidity and mortality. We determined the incidence and risk factors for PPMV in children who underwent OLT. Methods. This was a retrospective analysis of data collected on 128 pediatric OLT recipients. PPMV was defined as postoperative ventilation ≥ 4 days. Perioperative characteristics were compared between cases and control groups. Multivariable logistic regression analysis was used to calculate odds ratios for PPMV after controlling for relevant cofactors. Results. An estimated 25% (95% CI, 17.4%–32.6% required PPMV. The overall incidence of PPMV varied significantly by age group with the highest incidence among infants. PPMV was associated with higher postoperative mortality (p=0.004 and longer intensive care unit (p<0.001 and hospital length of stay (p<0.001. Multivariable analysis identified young patient age, preoperative hypocalcemia, and increasing duration of surgery as independent predictors of PPMV following OLT. Conclusion. The incidence of PPMV is high and it was associated with prolonged ICU and hospital LOS and higher posttransplant mortality. Surgery duration appears to be the only modifiable predictor of PPMV.

    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.

    The mammalian target of rapamycin (mTOR) inhibitor is an immunosuppressive drug used in kidney transplantation. Whether the mTOR inhibitor is associated with reduced risk of cancer development and mortality after kidney transplantation is controversial. We conducted a nationwide population-based study. Patients who did not have malignancy history and received kidney transplantation between 2010 and 2013 were enrolled. Recipients who had mTOR inhibitors (n = 430) for more than 30 days comprised the study group; 1720 recipients who did not have mTOR inhibitors comprised the control group. The primary outcome is the development of cancer after kidney transplantation. These patients were followed until the first-time admission with diagnosis of cancer, death, or the end of 2014. A Cox proportional-hazard model was used to determine the risk of cancer development and all-cause mortality. During the 35-month median duration of observation, there were 16 and 61 patients with cancer development in the study group and the control group, respectively. The cancer incidence was 12.8 and 12.4 per 1000 person-years. There were 10 and 135 mortality cases, with the incidence rate of 7.8 and 26.9 per 1000 person-years. After multivariable adjustment, the mTOR inhibitors users were not associated with reduced risk of new cancer development as compared with control (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.46-1.60; P = .63), nor risk of all-cause mortality (HR, 0.70; 95% CI, 0.33-1.46; P = .34). The use of mTOR inhibitors was not associated with a reduction in the risk of cancer development and all-cause mortality in kidney transplantation recipients. Copyright © 2016 Elsevier Inc.

    Full Text Available The objective of this study was to evaluate the incidence of genital human papilloma virus (HPV infection and cervical intra-epithelial lesions in transplanted patients. Cervical Papanicolaou (Pap smear/HPV test and colposcopic examinations were performed in 58 patients who were candidates for renal transplant surgery; these tests were repeated one year later. Their age range was 26-53 years (mean, 37.2 years. Hypertension was the most common cause of renal insufficiency (34.4%, while in 41.4% of the patients, the causative pathology was unknown. In 24.1% of the patients, there was no history of dialysis, i.e. they had pre-emptive transplantation. The mean duration of marriage (years since first intercourse was 16.2 years (range, 1-35. Coitus interruptus was the most common contraceptive method used (37.9%, followed by tubal ligation and condom (10.3% and 6.9%, respectively. All patients had negative Pap tests and normal gynecologic exam before undergoing transplantation. The Pap test remained normal after transplant surgery, although the HPV test became positive in four patients (6.9%. There were five cases of white epithelium on colposcopy, but biopsy showed normal metaplasia. Two cases of extensive anogenital warts were treated by CO 2 laser, and one patient had recurrent warts, which responded well to second laser surgery. None of the study patients had squamous intra-epithelial lesions (SIL or vulvar intra-epithelial neoplasia. Our study suggests that screening with HPV and Pap test should be performed before transplant surgery and should be repeated at regular intervals in order to avoid irreversible situations such as high-grade SILs, which are difficult to treat. Avoiding high-risk sexual relations in this group of patients is highly recommended.

    Liver transplantation using blood culture positive donors (BCPD) has allowed a significant expansion of the donor pool. We aimed to characterize BCPD and assess the outcomes of BCPD liver transplant recipients. We retrieved data from the United Network for Organ Sharing (UNOS) registry on all adults who underwent primary, single-organ deceased-donor liver transplantation in the USA between 2008 and 2013. Patients were classified into two cohorts: the BCPD cohort and the non-BCPD cohort. One-year graft and patient survival were compared between cohorts using Kaplan-Meier estimates and Cox models. A total of 28 961 patients were included. There were 2316 (8.0%) recipients of BCPD. BCPD were more likely to be older, female, black, diabetic, hypertensive, and obese compared to non-BCPD. Graft survival was significantly lower in BCPD recipients compared to non-BCPD recipients (Kaplan-Meier, 0.85 vs. 0.87; P = 0.009). Results remained significant in propensity-matched analysis (P = 0.038). BCPD was independently associated with decreased graft survival (adjusted HR; 1.10, 95% CI 1.01-1.20; P = 0.04). There were no significant differences in patient survival between study groups. BCPD was associated with decreased graft survival in liver transplant recipients. Studies are needed to identify subgroups of BCPD with the highest risk of graft failure and characterize the underlying pathogenic mechanisms. © 2016 Steunstichting ESOT.

    Sleep disruption is common among hematopoietic cell transplant (HCT) recipients, with over 50% of recipients experiencing sleep disruption pre-transplant, with up to 82% of patients experiencing moderate to severe sleep disruption during hospitalization for transplant and up to 43% after transplant. These rates of sleep disruption are substantially higher than what we see in the general population. Although sleep disruption can be distressing to patients and contribute to diminished quality of life, it is rarely discussed during clinical visits. The goal of the current review is to draw attention to sleep disruption and disorders (ie, insomnia, obstructive sleep apnea, restless legs syndrome) as a clinical problem in HCT in order to facilitate patient education, intervention, and research. We identified 35 observational studies published in the past decade that examined sleep disruption or disorders in HCT. Most studies utilized a single item measure of sleep, had small sample size, and included heterogeneous samples of patients. Six studies of the effects of psychosocial and exercise interventions on sleep in HCT have reported no significant improvements. These results highlight the need for rigorous observational and interventional studies of sleep disruption and disorders in HCT recipients..

    Pregnancies in patients with solid organ transplants have higher rates of complications and caesarean sections (CS). To perform an audit of the pregnancy outcomes in transplant recipients, to determine the rate of CS in our cohort, the appropriate skin incision for CS in these patients and to formulate recommendations for preoperative planning. This is a retrospective cohort study. All patients who had a solid organ transplant were identified from the obstetrics database. The operation records of the transplant recipients who delivered by CS were reviewed and the de-identified data were evaluated for pregnancy outcomes. This cohort consisted of 22 women: six had simultaneous pancreas and kidney (SPK) transplants and 16 had kidney transplants. Over a ten-year period, four women had two pregnancies and one had a twin pregnancy, thus 27 babies were born. The rate of CS was 58% (n = 15) and the surgical approach in 13 of these patients was by Pfannenstiel incision. One patient had an elective midline incision at the first CS, which was repeated in the next pregnancy. Two CS were complicated by bladder injury, both occurring in SPK recipients. Patients with solid organ transplants have a higher rate of CS and SPK patients may be at a higher risk of bladder injuries during CS. Our data suggest that Pfannenstiel skin incision is still suitable for these patients. We recommend reviewing the operative details of the transplant operation and a pelvic magnetic resonance imaging for pre-operative planning. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Aim of study: multiplex analysis of the levels of biomarkers of neoangiogenesis and inflammation in cardiac transplant recipients. Materials and methods. 59 pts. with heart failure III–IV according to NYHA FC, waiting for a heart transplant, aged 22 to 73 years, 48 males and 11 females. 41 recipient (30 men and 11 women had dilated cardiomyopathy, 18 – coronary heart disease (CHD. The concentration of VEGF-A, VEGF-D, PlGF, PDGF-BB, FGF, sCD40L, MCP-1 was measured using xMAP technology, the sets of reagents Simplex ProcartaPlexTM (Affymetrix, USA. Results. There are four levels of seven biomarkers of neoangiogenesis and inflammation method for multiplex analysis in patients with heart failure. A year after transplantation, the mean levels of biomarkers VEGF-A (p = 0.001, PDGF-BB (p = 0.018, MCP-1 (p = 0.003 was significantly decreased, and the others had a tendency to decrease relative to the level before transplantation. It was shown individual differences of levels of VEGF-A, VEGF-D and PlGF before and after transplantation. There were found different dynamics of the concentrations of biomarkers and growth factors before and after heart transplantation in patients with cardiovascular complications and without them. Conclusion. Multiplex analysis allows to measure the concentration range of analyte biomarkers of neoangiogenesis, inflammation in one sample of blood serum of patients with severe heart failure and after transplantation. There are marked individual differences in the concentration of biomarkers in different clinical situations that may have clinical significance in the conduct and supervision of recipients after transplantation.

    In developed countries, hepatitis E virus (HEV) is considered an emerging pathogen, but prevalence seems highly variable according to previous European studies. As HEV can lead to chronic infections in immunosuppressed patients, it is thus essential to evaluate the prevalence and incidence of this infection. We determined retrospectively, in a cohort of 206 pediatric and adult liver transplant recipients from the Rhône-Alpes region in France, pre-transplant anti-HEV-IgG prevalence and incidence of HEV infections during post-transplant follow-up (HEV IgG and IgM ± HEV-RNA). Transplantations were carried out between 2005 and 2012 and mean post-transplant follow-up was 32.8 months. Global pre-transplant prevalence of anti-HEV IgG was 29%, increasing regularly with age from 7% for children under 15 to 49% for patients older than 60. From the 142 seronegative patients before transplant, 11 seroconversions (7.7%) were observed during follow-up (incidence of 2.83 cases per 100 person-years). HEV RNA-tested at transaminases peak or randomly-was detected in only one case of seroconversion. For at least 2 HEV-seropositive patients, who had negative RNAemia before transplantation, viral RNA was detected chronically during follow-up, suggesting reinfection with HEV. Acute infections were largely more frequent than chronic infections and were asymptomatic or misdiagnosed, suggesting that liver transplant patients may not be particularly prone to developing severe HEV hepatitis. In addition, the presence of IgG anti-HEV may not protect against re-infection. Serological testing, therefore, appears to be of limited interest for the diagnosis of HEV infections in liver transplant recipients.

    Full Text Available As increasing numbers of older people are listed for solid organ transplantation, there is an urgent need to better understand how aging modifies alloimmune responses. Here, we investigated whether aging impairs the ability of donor dendritic cells or recipient immunity to prime alloimmune responses to organ transplantation.Using murine experimental models, we found that aging impaired the host environment to expand and activate antigen specific CD8(+ T cells. Additionally, aging impaired the ability of polyclonal T cells to induce acute allograft rejection. However, the alloimmune priming capability of donor dendritic cells was preserved with aging.Aging impairs recipient responses, both T cell intrinsic and extrinsic, in response to organ transplantation.

    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.

    Coronary artery calcifications (CACs) represent an important risk factor of coronary artery disease in the general population. The purpose of the study was to determine the amount of CAC, including calcium mass, in renal graft recipients early after transplantation. Forty-nine patients aged 43.7+/-9.8 years underwent CAC determination with multi-detector row computed tomography within two weeks after transplantation. The calcium scores were compared with the clinical and laboratory data of the subjects. CACs were detected in 73% of the subjects. The mean calcium score (CS) was 500.8+/-1100.4 and the mean calcium mass (CM) 127.0+/-228.6 mg. Presence of diabetes, duration of hypertension, and diastolic blood pressure (DBP) were significantly associated with the presence of CAC in univariate analysis. CS and CM positively correlated with duration of hypertension, time on dialysis, and pulse pressure (PP) and negatively with DBP. In multiple regression analysis the duration of hypertension, DBP, and PP were identified as independent predictors of CAC presence (p<0.01), while the time on dialysis and DBP were independent predictors of CAC severity (p<0.02). The results suggest that hypertension may play a crucial role in the development of coronary artery calcifications in end-stage renal disease patients, but the nature of the relation between CAC and blood pressure needs further investigation.

    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.)

    To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management. A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted. Pseudoaneurysms were classified into iatrogenic (associated with biliary endoprosthesis or angioplasty) or spontaneous extrahepatic pseudoaneurysms. Spontaneous and iatrogenic pseudoaneurysms were compared for time from transplant, presenting symptoms, location in the arterial anatomy, and 3-month graft survival. Arterial patency and 6-month graft survival were calculated. Twenty pseudoaneurysms were found (1.1 %, 20/1,857): 9 (0.5 % of transplants, 9/1,857) were spontaneous and 11 (0.6 % of transplants, 11/1,857) were 'iatrogenic' (due to minimally invasive procedures: 4 angioplasty and 7 biliary endoprostheses). Sixty percent (12/20) underwent endovascular management (4 coil embolization and 8 stent-grafts). Technical success was 83 % (10/12) with a mean arterial patency of 70 % (follow-up mean, 4.9; range, 0-18 months). The 1-, 3-, and 6-month graft survival was 70, 40, and 35 %, respectively. Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.

    Pregnancy after solid organ transplantation is becoming more common, with the largest recorded numbers in renal and liver transplant recipients. Intestinal transplantation is relatively new compared to other solid organs, and reports of successful pregnancy are far less frequent. All pregnancies reported to date in intestinal transplant recipients have been in women with stable graft function. The case reported here involves the first reported successful term pregnancy in an intestine-pancreas transplant recipient with chronic graft dysfunction and dependence on both transplant immunosuppression and parenteral nutrition (PN) at the time of conception. Pregnancy was unplanned and unexpected in the setting of chronic illness and menstrual irregularities, discovered incidentally on abdominal ultrasound at approximately 18 weeks' gestation. Rapamune was held, tacrolimus continued, and PN adjusted to maintain consistent weight gain. A healthy female infant was delivered vaginally at term. Medical complications during pregnancy included anemia and need for tunneled catheter replacements. Ascites and edema were improved from baseline, with recurrence of large volume ascites shortly after delivery. Successful pregnancy is possible in the setting of transplant immunosuppression, chronic intestinal graft dysfunction, and long-term PN requirement, but close monitoring is required to ensure the health of mother and child.

    The prevalence of hypertension in renal transplant recipients is high but the pathophysiology is poorly defined. Impaired endothelial function may be a factor of major importance. The present study addresses the effects of long-term treatment with either lisinopril or slow-release nifedipine on microvascular function and plasma endothelin in renal transplant recipients on cyclosporin A (CsA). Seventy-five hypertensive renal transplant recipients were double-blind randomized to receive slow-release nifedipine (NIF, n=40) or lisinopril (LIS, n=35). Ten normotensive, age-matched recipients served as controls. All patients received CsA-based immunosuppressive therapy including prednisolone and azathioprine. Microvascular function was assessed in the forearm skin vasculature, using laser Doppler flowmetry in combination with post-occlusive reactive hyperaemia and endothelial-dependent function during local acetylcholine (ACh) stimulation. The analysis of microvascular function (AUC(rh)) showed that nifedipine-treated patients had significantly lower responses compared with lisinopril-treated patients (20+/-17 and 43+/-20 AU x min respectively, P=0.0016). Endothelial function was borderline significantly lower in the NIF group compared with the LIS group (640+/-345 and 817+/-404 AU x min respectively, P=0.056). The responses in the LIS group were comparable with those in non-hypertensive controls (AUC(rh) was 37+/-16 and AUC(ACh) was 994+/-566 AU x min). Plasma endothelin-1 concentrations were significantly higher in the NIF group compared with the LIS group (0.44+/-0.19 vs. 0.34+/-0.10 fmol/ml respectively, P=0.048), and were 0.29+/-0.09 fmol/ml in the control patients. AUC(ACh) was associated with plasma endothelin-1 (P=0.0053), while AUC(rh) was not (P=0.080). The study indicates that long-term treatment with lisinopril, when compared with nifedipine, yields a more beneficial effect on microvascular function in hypertensive renal transplant recipients on CsA.

    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.

    Full Text Available The role of infection with Mycoplasma hominis following cardiothoracic organ transplantation and its source of transmission have not been well-defined. Here, we identify and describe infection with M. hominis in patients following cardiothoracic organ transplantation after reviewing all cardiothoracic transplantations performed at our center between 1998 and July 2015. We found seven previously unreported cases of M. hominis culture positive infection all of whom presented with pleuritis, surgical site infection, and/or mediastinitis. PCR was used to establish the diagnosis in four cases. In two instances, paired single lung transplant recipients manifested infection, and in one of these pairs, isolates were indistinguishable by multilocus sequence typing (MLST. To investigate the prevalence of M. hominis in the lower respiratory tract, we tested 178 bronchoalveolar lavage (BAL fluids collected from immunocompromised subjects for M. hominis by PCR; all were negative. Review of the literature revealed an additional 15 cases of M. hominis in lung transplant recipients, most with similar clinical presentations to our cases. We recommend that M. hominis should be considered in post-cardiothoracic transplant infections presenting with pleuritis, surgical site infection, or mediastinitis. M. hominis PCR may facilitate early diagnosis and prompt therapy. Evaluation for possible donor transmission should be considered.

The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation. Our patient had received a living-related-donor renal transplant due to chronic renal failure. In the second year of transplantation, she had been injured in a motor-vehicle accident, and radiographs showed a right acetabular anterior column fracture and left pubic rami fractures. The patient was treated with percutaneous fixation techniques and at one year of postoperative period there was no evidence of degenerative signs and the clinical outcome was good. Beside having the advantage of avoiding dissection through the iliac fossa by the standard ilioinguinal approach, percutaneous techniques, with shorter surgical time, decreasing soft tissue disruption, and the potential for early discharge from hospital might be ideal for a renal transplant recipient carrying a higher risk of infection. Percutaneous fixation of selected acetabular fractures in a renal transplant recipient would presumably have the potential to decrease the morbidity associated with traditional open surgical procedures.

    Cystatin C and beta-2-microglobulin (B2M) are filtration markers associated with adverse outcomes in nontransplant populations, sometimes with stronger associations than for creatinine. We evaluated associations of estimated glomerular filtration rate from cystatin C (eGFR cys ), B2M (eGFR B 2M ), and creatinine (eGFR cr ) with cardiovascular outcomes, mortality, and kidney failure in stable kidney transplant recipients using a case-cohort study nested within the Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) Trial. A random subcohort was selected (N = 508; mean age 51.6 years, median transplant vintage 4 years, 38% women, 23.6% nonwhite race) with enrichment for cardiovascular events (N = 306; 54 within the subcohort), mortality (N = 208; 68 within the subcohort), and kidney failure (N = 208; 52 within the subcohort). Mean eGFR cr , eGFR cys , and eGFR B 2M were 46.0, 43.8, and 48.8 mL/min/1.73m 2 , respectively. After multivariable adjustment, hazard ratios for eGFR cys and eGFR B 2M mortality; and 9.49 (4.28-21.00) and 15.53 (6.99-34.51; both p mortality, and kidney failure in stable kidney transplant recipients. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    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.

    Intravenous fluid management for deceased donor kidney transplantation is an important, modifiable risk factor for delayed graft function (DGF). The primary objective of this study was to determine if goal-directed fluid therapy using esophageal Doppler monitoring (EDM) to optimize stroke volume (SV) would alter the amount of fluid given. This randomized, proof-of-concept trial enrolled 50 deceased donor renal transplant recipients. Data collected included patient characteristics, fluid administration, hemodynamics, and complications. The EDM was used to optimize SV in the EDM group. In the control group, fluid management followed the current standard of practice. The groups were compared for the primary outcome of total intraoperative fluid administered. There was no difference in the mean (standard deviation) volume of intraoperative fluid administered to the 24 control and 26 EDM patients [2,307 (750) mL vs 2,675 (842) mL, respectively; mean difference, 368 mL; 95% confidence interval (CI), - 87 to + 823; P = 0.11]. The incidence of complications in the control and EDM groups was similar (15/24 vs 17/26, respectively; P = 0.99), as was the incidence of delayed graft failure (8/24 vs 11/26, respectively; P = 0.36). Goal-directed fluid therapy did not alter the volume of fluid administered or the incidence of complications. This proof-of-concept trial provides needed data for conducting a larger trial to determine the influence of fluid therapy on the incidence in DGF in deceased donor kidney transplantation. www.clinicaltrials.gov (NCT02512731).

    Obesity is prevalent in children with chronic kidney disease (CKD), but the health consequences of this combination of comorbidities are uncertain. The aim of this study was to evaluate the impact of obesity on the outcomes of children following kidney transplantation. Using data from the ANZDATA Registry (1994-2013), we assessed the association between age-appropriate body mass index (BMI) at the time of transplantation and the subsequent development of acute rejection (within the first 6 months), graft loss and death using adjusted Cox proportional hazards models. Included in our analysis were 750 children ranging in age from 2 to 18 (median age 12) years with a total of 6597 person-years of follow-up (median follow-up 8.4 years). Overall, at transplantation 129 (17.2%) children were classified as being overweight and 61 (8.1%) as being obese. Of the 750 children, 102 (16.2%) experienced acute rejection within the first 6 months of transplantation, 235 (31.3%) lost their allograft and 53 (7.1%) died. Compared to children with normal BMI, the adjusted hazard ratios (HR) for graft loss in children who were underweight, overweight or diagnosed as obese were 1.05 [95% confidence interval (CI) 0.70-1.60], 1.03 (95% CI 0.71-1.49) and 1.61 (95% CI 1.05-2.47), respectively. There was no statistically significant association between BMI and acute rejection [underweight: HR 1.07, 95% CI 0.54-2.09; overweight: HR 1.42, 95% CI 0.86-2.34; obese: HR 1.83, 95% CI 0.95-3.51) or patient survival (underweight: HR 1.18, 95% CI 0.54-2.58, overweight: HR 0.85, 95% CI 0.38-1.92; obese: HR 0.80, 95% CI 0.25-2.61). Over 10 years of follow-up, pediatric transplant recipients diagnosed with obesity have a substantially increased risk of allograft failure but not acute rejection of the graft or death.

    Loss of bone mass and increased fracture risk are known complications after renal transplantation in adults. Risk factors include donor source, dialysis status prior to transplantation, aetiology of renal disease, transplant rejection and drug therapy, particularly steroids. In this preliminary study of quantification of bone loss in children after renal transplantation, we evaluated the applicability of digital X-ray radiogrammetry (DXR) of hand radiographs to estimate cortical bone mineral density (DXR-BMD). A total of 23 renal transplant recipients (9 girls, 14 boys; age 6.5-20 years, median 16.3 years) underwent DXR measurements for calculation of DXR-BMD and metacarpal index (DXR-MCI) using radiographs of the non-dominant left hand. The duration between transplantation and the DXR evaluation, the duration of dialysis and medication were considered. The results were compared to a local age-matched and gender-matched reference data base. Our study revealed a significant decrease in bone mineral density compared to an age-matched and sex-matched normal population (P<0.05). In three patients the DXR-BMD was reduced more than -2.5 SD. In 12 patients the DXR-BMD was between -1 and -2.5 SD, and in 7 patients the DXR-BMD was in the normal range. In one patient, evaluation was not possible. Fractures were documented in three patients following transplantation. Reduced DXR-BMD was not significantly associated with immunosuppressive therapy or the duration of dialysis, and there was no significant correlation between DXR-BMD and the time between transplantation and DXR evaluation.

    To compare the safety and efficacy of rabbit antithymocyte globulin (r-ATG) with basiliximab in renal transplant recipients for whom an early steroid withdrawal (ESW) regimen was planned. Single-center, retrospective, cohort study. Tertiary care medical center, including inpatient hospital stays and outpatient nephrology clinics. Ninety-nine consecutive adult recipients of living- or deceased-donor renal transplants between January 1, 2004, and December 31, 2007, in whom ESW was planned and who received either r-ATG or basiliximab; patients receiving an extended-criteria kidney donation or a donation after cardiac death were excluded. All patients received mycophenolate mofetil and tacrolimus as maintenance therapy with planned ESW. Induction therapy was either r-ATG 1.5 mg/kg/day for 4 days (68 patients) or basiliximab 20 mg on postoperative days 0 and 4 (31 patients). The primary composite end point of biopsy-proven acute rejection (BPAR), graft loss, and death occurred in 6 patients (9%) and 9 patients (29%) in the r-ATG and basiliximab groups at 1 year after transplantation, respectively (p=0.01), with rates of 7% (5/68 patients) and 26% (8/31 patients) for BPAR (p=0.02), 0% and 3% (1/31 patients) for graft loss (p=0.31), and 2% (1/68 patients) and 0% for patient death (p>0.99). Average time to first BPAR was significantly longer in the r-ATG group (mean ± SD 151.4 ± 82.9 vs 53.6 ± 68.4 days, p<0.01). Kidney function at 12 months was similar between the two groups. Rabbit-ATG was associated with a lower frequency and delayed onset of BPAR compared with basiliximab in renal transplant recipients who received an ESW regimen.

    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.

    Among adult kidney transplant recipients, non-adherence to immunosuppressive medications is the leading predictor of poor outcomes, including rejection, kidney loss, and death. An alarming one-third of kidney transplant patients experience medication non-adherence even though the problem is preventable. Existing adherence interventions have proven marginally effective for those with acute and chronic illnesses and ineffective for adult kidney transplant recipients. Our purpose is to describe the design and methods of the MAGIC (Medication Adherence Given Individual SystemCHANGE™) trial We report the design of a randomized controlled trial with an attention-control group to test an innovative 6-month SystemCHANGE™ intervention designed to enhance immunosuppressive medication adherence in adult non-adherent kidney transplant recipients from two transplant centers. Grounded in the Socio-Ecological Model, SystemCHANGE™ seeks to systematically improve medication adherence behaviors by identifying and shaping routines, involving supportive others in routines, and using medication taking feedback through small patient-led experiments to change and maintain behavior. After a 3-month screening phase of 190 eligible adult kidney transplant recipients, those who are adherent as measured by electronic monitoring, will be randomized into a 6-month SystemCHANGE™ intervention or attention-control phase, followed by a 6-month maintenance phase without intervention or attention. Differences in adherence between the two groups will be assessed at baseline, 6 months (intervention phase) and 12 months (maintenance phase). Adherence mediators (social support, systems-thinking) and moderators (ethnicity, perceived health) are examined. Patient outcomes (creatinine/blood urea nitrogen, infection, acute/chronic rejection, graft loss, death) and cost effectiveness are to be examined. Based on the large effect size of 1.4 found in our pilot study, intervention shows great promise

    Full Text Available Cell-free DNA (cfDNA has significant potential in the diagnosis and monitoring of clinical conditions but accurately and easily distinguishing the relative proportion of DNA molecules in a mixture derived from two different sources (i.e. donor and recipient tissues after transplantation is challenging. In human cellular transplantation there is currently no useable method to detect in vivo engraftment and blood-based non-invasive tests for allograft rejection in solid organ transplantation are either non-specific (e.g. creatinine in kidney transplantation, liver enzymes in hepatic transplantation or absent (i.e. heart transplantation. Elevated levels of donor cfDNA have been shown to correlate with solid organ rejection but complex methodology limits implementation of this promising biomarker. We describe a cost-effective method to quantify donor cfDNA in recipient plasma using a panel of high-frequency single nucleotide polymorphisms, next-generation (semiconductor sequencing and a novel mixture model algorithm. In vitro, our method accurately and rapidly determined donor/recipient DNA admixture. For in vivo testing, donor cfDNA was serially quantified in an infant with a urea cycle disorder after receiving six daily infusions of donor liver cells. Donor cfDNA isolated from 1-2 ml of recipient plasma was detected as late as 24 weeks after infusion suggesting engraftment. The percentage of circulating donor cfDNA was also assessed in pediatric and adult heart transplant recipients undergoing routine endomyocardial biopsy with levels observed to be stable over time and generally measuring <1% in cases without moderate or severe cellular rejection. Unlike existing non-invasive methods used to define the proportion of donor cfDNA in solid organ transplant patients, our assay does not require sex mismatch, donor genotyping or whole-genome sequencing and potentially has broad application to detect cellular engraftment or allograft injury after

    Medication nonadherence is a known problem after renal transplantation and can vary from one setting to another. Since it can lead to negative outcomes, it is important to develop intervention strategies to enhance adherence in a given setting using determinants identified through exploratory studies. We explored nonadherence in renal transplant recipients. A longitudinal survey was done with adult renal transplant recipients at a tertiary care public and two private hospitals of Kolkata. Subjects were followed-up for 1 year. After screening for medication adherence status by the four-item Morisky Medication Adherence Scale, those admitting to potential nonadherence were probed further. A patient was deemed to be nonadherent if failing to take medicines on appointed time (doses missed or delayed by more than 2 h) more than three times in any month during the observation period. A pretested questionnaire was used to explore potential determinants of nonadherence. Data of 153 patients recruited over a 2-year were analyzed. The extent of nonadherence with immunosuppressant regimens was about 31% overall; 44% in the public sector and 19% in the private sector ( P transplant recipients in the Indian setting. Strategies to improve medication adherence can be planned by relevant stakeholders on the basis of these findings.

    Nonadherence to immunosuppressive drugs is a concern among kidney transplantation recipients (KTRs). The adverse effects of immunosuppressive drugs can trigger nonadherence and lead to a great impact on the allograft survival. The aim of this prospective controlled study is to determine the major adverse effects of immunosuppressive drugs and their correlation with the nonadherence in kidney transplantation recipients. All data were collected from medical and pharmacy records. We use modified Immunosuppressant Therapy Adherence Scale combined with Modified Transplant Symptom Occurrence and Symptom Distress scale to explore the relationship between symptom experience related to side effects of immunosuppressants and adherence. The risk of nonadherence was estimated by stepwise logistic regression while controlling for age, gender, education, and immunosuppressive medications. Multivariable analysis was performed using a single random effect of P adherence increased in patients with awareness of memory impairment (odds ratio 2.320, 95% confidence interval: 1.259-4.274, P = .007). There was no significant difference in the incidence of acute rejection, gender, age, and education between adherent and nonadherent patients. In summary, these results indicate a significant prevalence of nonadherence to immunosuppressive drugs in kidney transplantation recipients. Awareness of memory impairment significantly affected adherence to immunosuppressive drugs. Copyright © 2012 Elsevier Inc. All rights reserved.

    Although outcome inequalities for non-Hispanic Black (NHB) kidney transplant recipients are well documented, there is paucity in data assessing the impact of cardiovascular disease (CVD) risk factors on this disparity in kidney transplantation. This was a longitudinal study of a national cohort of veteran kidney recipients transplanted between Jan 2001 and Dec 2007. Data included baseline characteristics acquired through the USRDS linked to detailed clinical follow up information acquired through the VA electronic health records. Analyses were conducted using sequential multivariable modeling (Cox regression), incorporating blocks of variables into iterative nested models; 3,139 patients were included (2,095 NHW [66.7%] and 1,044 NHBs [33.3%]). NHBs had a higher prevalence of hypertension (100% vs. 99%, ptransplant diabetes (59% vs. 53%, pAdherence to medications used to manage CVD risk was significantly lower in NHBs. In the fully adjusted models, the independent risk of graft loss in NHBs was substantially reduced (unadjusted HR 2.00 vs. adjusted HR 1.49). CVD risk factors and control reduced the influence of NHB race by 9–18%. Similar trends were noted for mortality and estimates were robust across in sensitivity analyses. These results demonstrate that NHB kidney transplant recipients have significantly higher rates of CVD risk factors and reduced CVD risk control. These issues are likely partly related to medication non-adherence and meaningfully contribute to racial disparities for graft outcomes. PMID:27402921

    Human endogenous retrovirus (HERVs) constitute approximately 8% of the human genome. Induction of HERV transcription is possible under certain circumstances, and may have a possible role in some pathological conditions. The aim of this study was to evaluate HERV-K and -W pol gene expression in kidney transplant recipients and to investigate the possible relationship between HERVs gene expression and CMV infection in these patients. Thirty-three samples of kidney transplant patients and twenty healthy blood donors were used to analyze, HERV-K and -W pol gene RNA expression by relative quantitative relative Real-Time PCR. We demonstrated that HERVs pol gene expression levels were higher in kidney transplant recipients than in healthy subjects. Moreover, HERV-K and -W pol gene expression was significantly higher in the group of kidney transplant recipients with high CMV viral load than in the groups with no or moderate CMV viral load. Our data suggest that CMV may facilitate in vivo HERV activation. Published by Elsevier B.V.

    To report what we believe to be the first 2 cases of long-term (>24 months) intermittent intravenous interleukin-2 receptor antibody (IL-2RA) therapy for maintenance immunosuppression following renal transplantation. The first patient is a 52-year-old female with a history of intolerance to calcineurin inhibitors (CNIs) and sirolimus. Following her second transplant, the patient received mycophenolate mofetil 100 mg twice daily, a tapering corticosteroid regimen (initial dose of methylprednisolone 500 mg tapered over 1 week to prednisone 30 mg/day), and biweekly intravenous daclizumab 1-1.2 mg/kg/dose; 33 months after transplant the IL-2RA was changed to intravenous basiliximab 40 mg once a month. At 40 months after transplant, the patient continued to have stable renal function (estimated glomerular filtration rate 48 mL/min/1.73 m²) with excellent tolerability. The second patient is a 59-year-old female also intolerant to CNIs and sirolimus who required intermittent maintenance therapy with intravenous basiliximab 20 mg/dose. Despite an initial rejection episode, the patient tolerated more than 2 years of basiliximab therapy with good renal function (estimated glomerular filtration rate 103 months after transplant 69 mL/min/1.73 m²) and no adverse events. The IL-2RAs basiliximab and daclizumab possess several characteristics of ideal maintenance immunosuppressive agents (ie, nondepleting, long half-lives, limited adverse events). Based on a MEDLINE search (through December 31, 2010) using the search terms basiliximab, daclizumab, organ transplant, immunosuppression, and/or maintenance immunosuppression, and an advanced search in the published abstracts from the American Transplant Congress and World Transplant Congress (2000-2010), it appears that IL-2RAs have been used successfully as short-term therapy in both renal and extrarenal transplant recipients to allow for renal recovery following CNI-induced nephrotoxicity. In heart transplant recipients, the IL-2

    To investigate the incidence and the determinants of cardiovascular morbidity in Greek renal transplant recipients (RTRs) expressed as major advance cardiac event (MACE) rate. 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.

    The purpose of this study was to investigate the relationship between immunosuppressant-related symptom experience (SE) and adherence to immunosuppressant regimens among kidney transplant (KT) recipients. A total of 239 KT recipients on an immunosuppressant regimen who were followed up after transplantation participated in this study. Data was collected through a self-reported questionnaire survey (medication adherence, SE, and quality of life) and medical record review. Low adherence in the immunosuppressant group was associated with longer time since KT, less comorbidity (adherence among KT recipients showed significantly greater overall symptom occurrence (P = .001) and symptom distress (P = .002) levels than patients with high or medium adherence after adjusting for a number of covariates. The most common symptom both in terms of occurrence (96.4%) and distress (91.1%) among poorly adherent KT recipients was tiredness. Low adherence to an immunosuppressant regimen was significantly associated with high SE among KT recipients. Strategies to decrease immunosuppressant-related SE are needed to improve adherence to immunosuppressants. Copyright © 2015 Elsevier Inc. All rights reserved.

    Kidney transplantation is now considered the treatment of choice for many human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). Graft survival rates using HIV-negative donors and carefully selected HIV-positive ESRD patients are similar to those observed in HIV-uninfected kidney transplant recipients. To address the relative shortfall in donated organs it has been proposed that organs from HIV-infected deceased donors might be allocated to HIV-infected patients on the transplant waiting list. Preliminary experience in South Africa reports promising short-term outcomes in a small number of HIV-infected recipients of kidney transplants from HIV-infected donors. We sought to replicate this experience in the UK by accepting kidney offers from HIV infected deceased donors for patients with HIV-infection on the kidney transplant waiting list. Here we report the UK's first cases of kidney transplantation between HIV-positive donors and recipients.

    The intestinal microbiome and immune system are in close symbiotic relationship in health. Gut microbiota plays a role in many chronic liver diseases and cirrhosis. However, alterations in the gut microbiome after liver transplantation and the implications for liver transplant recipients are not well understood and rely mainly on experimental animal studies. Recent advances in molecular techniques have identified that increased intestinal permeability, decreased beneficial bacteria, and increased pathogenic species may play important roles in the early posttransplant period. The associations between microbiota perturbation and postliver transplant infections and acute rejection are evolving. The link with metabolic syndrome, obesity, and cardiac disease in the general population require translation into the transplant recipient. This review focuses on our current knowledge of the known and potential interaction of the microbiome in the liver transplant recipient. Future human studies focused on microbiota changes in liver transplant patients are warranted and expected.

    Hepatitis E is caused by infection with the hepatitis E virus (HEV). HEV is transmitted orally via HEV-contaminated food or drink. Hepatitis E usually shows mild symptoms and is self-limiting in the general population; however, it may progress to chronic hepatitis in immunosuppressed patients such as recipients of organ transplantation. However, a few cases of acute hepatitis E have been reported in organ transplantation recipients. We herein report a case of acute hepatitis E in a 31-year-old male renal transplant recipient. The patient underwent renal transplantation 2 years ago, and his postoperative course was uneventful without rejection. After complaining of general fatigue and low-grade fever for 1 week, he was referred to and admitted to our hospital. Careful interview revealed that he ate undercooked pork 10 weeks prior. Blood analysis revealed liver dysfunction but was serologically negative for hepatitis A, B and C virus, cytomegalovirus infection and collagen diseases. Immunoglobulin A antibody against hepatitis E virus (HEV-IgA) was also negative at that point. After 2 weeks of admission, HEV-IgA and HEV-RNA were measured again as hepatitis E could not be ruled out due to history of ingestion of undercooked meat that may have been contaminated with HEV. At that time, HEV-IgA and HEV-RNA (genotype 3) were positive. Thus, an acute hepatitis E was diagnosed. His liver function gradually improved to within the normal range, and HEV-IgA and HEV-RNA were negative at 11 weeks after admission. In conclusion, we describe here a case of acute hepatitis E in a renal transplant recipient. Careful interview regarding the possibility of ingestion of HEV-contaminated food and repeated measurements of HEV-IgA were helpful in finalizing a diagnosis.

    De novo steatosis after liver transplant is common and can occur in up to one-third of patients who are transplanted for liver disease other than for nonalcoholic fatty liver disease. Genetic factors may influence posttransplant steatosis; in a posttransplant setting, donor or recipient genetic factors could also play roles. Genetic polymorphisms in the adiponectin gene have been associated with metabolic syndrome in the pretransplant setting. We aimed to assess the association between donor and recipient adiponectin polymorphisms and early posttransplant hepatic steatosis identified on liver biopsies. Clinical data were collected for 302 liver transplant patients who underwent protocol biopsies for hepatitis C. Of these, 111 patients had available biopsies and donor/recipient DNA. Patients with grade 1 steatosis or greater (35% of patients) were compared with patients without posttransplant steatosis with respect to clinical features and donor/recipient adiponectin polymorphism genotypes. Patients who developed posttransplant steatosis and those without steatosis were similar with respect to individual components of metabolic syndrome. The adiponectin polymorphisms rs1501299 G/G and rs17300539 G/G genotypes in recipients were associated with early posttransplant graft steatosis. We found no associations between graft steatosis and donor adiponectin polymorphisms. Genetic polymorphisms in the adiponectin gene of recipients (but not donors) are associated with early de novo posttransplant hepatic steatosis, independent of components of metabolic syndrome.

    Sensitization in kidney transplantation is associated with more acute rejections, inferior graft survival, and an increase in delayed graft function. This study was designed to evaluate the efficacy and safety of preoperative single bolus antithymocyte globulin (ATG) induction therapy in sensitized renal transplant recipients. Fifty-six cadaveric donor kidney transplant recipients were divided into two groups: Group I (nonsensitized group, n = 30) and group II (sensitized group, PRA>10%, n = 26). ATG was given as a single preoperative bolus induction therapy to group II (ATG IV; 9 mg/kg). The group I patients were treated with mycophenolate mofetil preoperatively as induction therapy. The basic immunosuppressive regimen included tacrolimus (FK-506) or cyclosporine, mycophenolate mofetil, and prednisolone. After hospital discharge, patients were followed on a routine outpatient basis for 12 months. Acute rejection episodes (ARE) occurred in 20% (6/30) of group I and 15.38% (4/26) of group II patients (P = NS). Infections occurred in eight patients (26.7%) as 11 episodes (36.7%), averaging 1.4 episodes per infected patient in group 1, and 6 patients (23.1%) for a total of 10 episodes (38.5%), averaging 1.7 episodes per infected patient, in group II (P = NS). Occurrence of side effects and hospital stay were almost comparable in the two groups. No delayed graft function was observed in either group. The 12-month actuarial patient and graft survival were 100% in Group I and II. A preoperative single bolus ATG induction therapy was an effective and safe therapeutic measure, yielding an acceptable acute rejection rate in presensitized renal transplant recipients.

    We present two cases of osteochondroma after total body irradiation in bone marrow recipients, the first in a 6-year-old boy with juvenile chronic myelogenous leukemia and the second in a 13-year-old boy with acute myelogenous leukemia. The patients developed multiple osteochondromas three years and seven years, respectively, after 12 Gy of total body irradiation. Neither had a family history of hereditary multiple osteochondromatosis. A review of the English literature revealed only one report describing five cases of osteochondroma after 12 Gy of total body irradiation in bone marrow transplant recipients. Osteochondroma should be considered as an additional adverse effect of total body irradiation. (author)

    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

    The utility of cardiac stress testing as a risk-stratification tool before kidney transplantation remains debatable owing to discordance with coronary angiography and outcome yields at different centers. We conducted a retrospective study of 273 diabetic kidney transplant recipients from 2006 to 2010. By protocol, all diabetic patients underwent pharmacological radionucleotide stress test or dobutamine stress echocardiography before transplant. We compared the 1-year cardiac outcomes between those with negative stress test results and those with positive stress test results. Patients with a positive stress test result (n=67) underwent coronary angiogram, and significant coronary artery disease (≥70% coronary stenosis) was found in 35 (52.2%) patients. Of the latter, 32 (91.4%) underwent cardiac revascularization (24 underwent cardiac stenting and 8 underwent coronary artery bypass grafting). The rest (n=35) were treated medically. Within 1 year after transplant, the group with positive stress test results experienced more cardiac events (34.3% vs. 3.9%, P<0.001) including acute myocardial infarction (22.4% vs. 3.4%, P<0.001) and ventricular arrhythmias (8.9% vs. 0.05%, P=0.001), higher all-cause mortality (19.4% vs. 4.8%, P<0.001), and cardiac mortality (17.9% vs. 0.9%, P<0.001) compared with the group with negative stress test results. In this diabetic population, stress testing showed positive and negative predictive values of 34.3% and 96.1%, respectively. Pharmacological cardiac stress testing provided excellent risk stratification in diabetic kidney transplant recipients.

    Full Text Available A 53-year-old renal allograft recipient developed nocardial cerebral abscess. It manifested clinically with encephalitis, polycythemia, convulsions, syndrome of inappropriate secretion of antidiuretic hormone (SIADH and a space-occupying lesion presenting as multiple ring shadows in the left fronto-parietal lobe on computerized tomography (CT scan of the brain. The initial clinical presentation included an afebrile patient with headache, convulsions and altered sensorium with no lateralising neurological deficit. He deteriorated later and developed coma with right hemiplegia. Purulent material was drained through left frontal craniotomy, and the culture confirmed the presence of nocardial infection. Despite aggressive therapy, the patient died a few days later. We conclude that high degree of early suspicion, diagnosis and prompt treatment should be stressed.

    In light of the recent changes to the kidney allocation system (KAS) and the observed increase in the rate of transplantation of the highly sensitized kidney transplant candidate, the evaluation and care of this population is a timely topic. In its first year, the new KAS has already realized one goal of improving the chances of transplanting the most highly sensitized patients in the waiting list. This has brought to the forefront the need for recipient readiness in this special population, as well as the need for histocompatibility labs and kidney transplant programs to align themselves with each other, and also with the requirements of the United Network for Organ Sharing, and increase proficiency in testing and data interpretation. This manuscript is a review of the literature as well as practice patterns as they relate to the changes in KAS and the observed outcome since the activation of the new KAS, with the ultimate goal of aiding in the development of a more unified approach in the care of this specialized population which will allow for interdisciplinary and cross centre dialogue to optimize long term care and outcomes. Here we will review the changes to the KAS as they affect the highly sensitized kidney transplant recipient, and additional considerations in the evaluation and management of these patients.

    Studies have continued to evaluate risk factors associated with post-transplant non-adherence in pediatric patients. However, many of these studies fail to evaluate how risk factors can be utilized to predict MNA. The aims of this study were to (i) determine salient risk factors associated with MNA to develop an adequate predictive risk model and (ii) assess transplant outcomes based on the presence of MNA in a large, diverse cohort of pediatric KTX recipients. One hundred and seventy-five solitary pediatric KTX recipients transplanted from 1999 to 2013 were included. AA, males, older patients, those who lived in urban environments, had legal issues, and lived shorter distances from the transplant center were more likely to have MNA. Using logistic regression, a parsimonious model applying nine risk factors together was developed for predicting MNA, demonstrating a PPV of 69% and a NPV of 81%. Patients with MNA had more than twice the risk of biopsy proven acute rejection, 1.6 times the risk of hospitalization, and 1.8 times the risk of graft loss. Utilization of a predictive model to determine risk of MNA after pediatric KTX may offer clinicians the ability to efficiently and effectively monitor MNA following transplant. © 2015 John Wiley & Sons A/S.

    Full Text Available Recipients of solid organ transplants (SOT have extensive diagnostic imaging (DI. The purpose of this study was to quantify this exposure. Children from northern Alberta with SOTs at Stollery Children's Hospital, Edmonton, Alberta January 1, 2006, to July 31, 2012, were included. Effective doses of radiation were estimated using published norms for DI performed post-transplant up to October 16, 2014. The 54 eligible children had 6215 DI studies (5628 plain films, 293 computerized tomography (CT scans, 149 positron emission topography (PET -CT scans, 47 nuclear medicine scans and 98 cardiac catheterizations. Children less than 5 years of age underwent more DI studies than did older children (median (IQR 140 (66-210 vs 49 (19-105, p = 0.010. Children with post-transplant lymphoproliferative disorder (N = 8 had more CT scans (median (IQR 13 (5.5-36 vs 1 (0-5, p100 mSv. In conclusion, a significant proportion of pediatric transplant recipients have sufficient radiation exposure post-transplant for DI to be at potential risk for radiation-induced malignancies.

    Full Text Available Mucormycosis is a rare but devastating infection. We present a case of fatal disseminated mucormycosis infection in a renal transplant patient. Uncontrolled diabetes mellitus and immunosuppression are the major predisposing factors to infection with Mucorales. Mucorales are angioinvasive and can infect any organ system. Lungs are the predominant site of infection in solid organ transplant recipients. Prompt diagnosis is challenging and influences outcome. Treatment involves a combination of surgical and medical therapies. Amphotericin B remains the cornerstone in the medical management of mucormycosis, although other agents have been used. Newer agents are promising.

    In heart transplant (HTx) recipients, there has been reluctance to recommend high-intensity interval training (HIIT) due to denervation and chronotropic impairment of the heart. We compared the effects of 12 weeks' HIIT versus continued moderate exercise (CON) on exercise capacity and chronotropic...... response in stable HTx recipients >12 months after transplantation in a randomized crossover trial. The study was completed by 16 HTx recipients (mean age 52 years, 75% males). Baseline peak oxygen uptake (VO2peak ) was 22.9 mL/kg/min. HIIT increased VO2peak by 4.9 ± 2.7 mL/min/kg (17%) and CON by 2.6 ± 2.......2 mL/kg/min (10%) (significantly higher in HIIT; p HIIT, systolic blood pressure decreased significantly (p = 0.037) with no significant change in CON (p = 0.241; between group difference p = 0.027).

    Currently, there is no specific immunosuppressive protocol for hepatitis C (HCV)-positive renal transplants recipients. Thus, the aim of this study was to evaluate the conversion effect to everolimus (EVR) on HCV in adult kidney recipients. This is an exploratory single-center, prospective, randomized, open label controlled trial with renal allograft recipients with HCV-positive serology. Participants were randomized for conversion to EVR or maintenance of calcineurin inhibitors. Thirty patients were randomized and 28 were followed-up for 12 months (conversion group, Group 1 =15 and control group, Group 2 =13). RT-PCR HCV levels reported in log values were comparable in both groups and among patients in the same group. The statistical analysis showed no interaction effect between time and group (p value G*M= 0.852), overtime intra-groups (p-value M=0.889) and between group (p-value G=0.286). Group 1 showed a higher incidence of dyslipidemia (p=0.03) and proteinuria events (p=0.01), while no difference was observed in the incidence of anemia (p=0.17), new onset of post-transplant diabetes mellitus (p=1.00) or urinary tract infection (p=0.60). The mean eGFR was similar in both groups. Our study did not show viral load decrease after conversion to EVR with maintenance of antiproliferative therapy.

  8. Aspergillus Tracheobronchitis Causing Subtotal Tracheal Stenosis in a Liver Transplant Recipient

    2013-01-01

    Full Text Available Invasive aspergillosis is recognized as one of the most significant opportunistic infections after liver transplantation. Diagnosis of invasive aspergillosis in transplant recipients has been proven to be challenging, and optimal approach to the treatment of invasive aspergillosis is still controversial. We here present an unusual case of Aspergillus tracheobronchitis in the setting of liver transplantation. A 47-year-old female patient with persistent dry cough after liver transplantation developed respiratory insufficiency and was readmitted to the intensive care unit 55 days after liver transplantation. A CT scan revealed subtotal tracheal stenosis; bronchoscopy was performed, and extended white mucus coverings causative of the tracheal stenosis were removed. Microbiological assessment isolated Aspergillus fumigatus. The diagnosis was obstructive Aspergillus tracheobronchitis. The patient was started on a treatment of voriconazole 200 mg orally twice daily, adjusted to a trough level of 1–4 mg/L. For further airway management, a tracheal stent had to be implanted. The patient is alive and well 28 months after liver transplantation. Invasive aspergillosis should be considered a possible etiology in liver transplant patients presenting with unspecific symptoms such as persistent dry cough. Optimal strategies for improved and early diagnosis as well as prophylaxis need to be defined.

    The aim of this study was to assess healthcare provider perspectives on barriers to medication adherence and to discover recommendations for interventions among providers of pediatric solid-organ transplant patients. An anonymous online survey was administered to a multidisciplinary pool of pediatric transplant providers from February 2015 to March 2016. It consisted of 15 questions regarding transplant providers' attitudes, clinical practice, and beliefs pertaining to medication adherence among teenage solid-organ transplant recipients. Data were analyzed using descriptive statistics. Responses to open-ended questions were coded and categorized into themes. One hundred ten surveys were completed by providers specializing in pediatric heart, kidney, liver, lung, and/or intestinal transplantation. Commonly cited reasons for poor adherence were forgetting/poor planning (94%), the desire to be normal (86%), lack of support (86%), and poor parental monitoring (79%). Suggestions to improve adherence included increasing peer and family support, providing education, and incorporating technology into adherence regimens. Barriers to adherence in transplant patients are recognized by providers and are both similar to and disparate from patient and family identified barriers published in the literature. Providers recognize the importance of education, social support, and technologically driven interventions on improving outcomes in the transplant population. © 2017 John Wiley & Sons A/S.

  10. Donor-Derived Myeloid Sarcoma in Two Kidney Transplant Recipients from a Single Donor

    Directory of Open Access Journals (Sweden)

    Amudha Palanisamy

    2015-01-01

    Full Text Available We report the rare occurrence of donor-derived myeloid sarcoma in two kidney transplant patients who received organs from a single deceased donor. There was no evidence of preexisting hematologic malignancy in the donor at the time of organ recovery. Both recipients developed leukemic involvement that appeared to be limited to the transplanted organ. Fluorescence in situ hybridization (FISH and molecular genotyping analyses confirmed that the malignant cells were of donor origin in each patient. Allograft nephrectomy and immediate withdrawal of immunosuppression were performed in both cases; systemic chemotherapy was subsequently administered to one patient. Both recipients were in remission at least one year following the diagnosis of donor-derived myeloid sarcoma. These cases suggest that restoration of the immune system after withdrawal of immunosuppressive therapy and allograft nephrectomy may be sufficient to control HLA-mismatched donor-derived myeloid sarcoma without systemic involvement.

    This study describes the development and psychometric testing of the Sexual Concerns Questionnaire (SCQ) in kidney transplant (KTx) recipients. Construct validity was assessed using the Kroonenberg and Lewis exploratory/confirmatory procedure and testing hypothesized relationships with established questionnaires. Configural and weak invariance were examined across gender, dialysis history, relationship status, and transplant type. Reliability was assessed with Cronbach's alpha, composite reliability, and test-retest reliability. Factor analysis resulted in a 7-factor solution and suggests good model fit. Construct validity was also supported by the tests of hypothesized relationships. Configural and weak invariance were supported for all subgroups. Reliability of the SCQ was also supported. Findings indicate the SCQ is a valid and reliable measure of KTx recipients' sexual concerns.

    To understand the stressors related to life post kidney transplantation, with a focus on medication adherence, and the coping resources people use to deal with these stressors. Although kidney transplantation offers enhanced quality and years of life for patients, the management of a kidney transplant post surgery is a complex process. A descriptive exploratory study. Participants were recruited from five kidney transplant units in Victoria, Australia. From March-May 2014, patients who had either maintained their kidney transplant for ≥8 months or had experienced a kidney graft loss due to medication nonadherence were interviewed. All audio-recordings of interviews were transcribed verbatim and underwent Ritchie and Spencer's framework analysis. Participants consisted of 15 men and 10 women aged 26-72 years old. All identified themes were categorised into: (1) Causes of distress and (2) Coping resources. Post kidney transplantation, causes of distress included the regimented routine necessary for graft maintenance, and the everlasting fear of potential graft rejection, contracting infections and developing cancer. Coping resources used to manage the stressors were first, a shift in perspective about how easy it was to manage a kidney transplant than to be dialysis-dependent and second, receiving external help from fellow patients, family members and health care professionals in addition to using electronic reminders. An individual well-equipped with coping resources is able to deal with stressors better. It is recommended that changes, such as providing regular reminders about the lifestyle benefits of kidney transplantation, creating opportunities for patients to share their experiences and promoting the usage of a reminder alarm to take medications, will reduce the stress of managing a kidney transplant. Using these findings to make informed changes to the usual care of a kidney transplant recipient is likely to result in better patient outcomes. © 2016 John

    The prevalence of Hepatitis C Virus (HCV) infection is significantly higher in patients with end-stage renal disease compared to the general population and poses important clinical challenges in patients who undergo kidney transplantation. Historically, interferon-based treatment options have been limited by low rates of efficacy and significant side effects, including risk of precipitating rejection. Limited data exist on the use of all-oral, interferon-free direct-acting antiviral (DAA) therapies in kidney transplant recipients. In this study, we performed a retrospective chart review with prospective clinical follow-up of post-kidney transplant patients treated with DAA therapies at three major hospitals in Boston, MA. A total of 24 kidney recipients with HCV infection received all-oral DAA therapy post-transplant. Patients were predominantly male (79%) with a median age of 60 years (range 34-70 years), median creatinine of 1.2 mg/dL (0.66-1.76), and 42% had advanced fibrosis or cirrhosis. The majority had HCV genotype 1a infection (58%). All patients received full-dose sofosbuvir; it was paired with simeprevir (9 patients without and 3 patients with ribavirin), ledipasvir (7 patients without and 1 patient with ribavirin) or ribavirin alone (4 patients). The overall sustained virologic response (SVR12) was 91% (21 out of 23 patients). One patient achieved SVR4 but demised prior to SVR12 check point due to treatment unrelated cause. Two treatment failures were successfully retreated with alternative DAA regimens and achieved SVR. Both initials failures occurred in patients with advanced fibrosis or cirrhosis, with genotype 1a infection, and prior HCV treatment failure. Adverse events were reported in 11 patients (46%) and were managed clinically without discontinuation of therapy. Calcineurin inhibitor trough levels did not significantly change during therapy. In this multi-center series of patients, all-oral DAA therapy appears to be safe and effective in post

    Cryptococcosis is the second most common cause of invasive fungal infections in renal transplant recipients in many countries, and data on graft outcome after treatment for this infection is lacking in less-resourced health care settings. Data from 47 renal transplant recipients were retrospectively collected at a single institution during a period of 13 years. Graft dysfunction, graft loss and mortality rates were evaluated. Predictors of mortality and graft loss were estimated. A total of 38 (97.4%) patients treated with amphotericin B deoxycholate (AMBd) showed graft dysfunction after antifungal initiation and 8 (18.2%) had kidney graft loss. Graft loss within 30 days after cryptococcosis onset was significantly associated with disseminated infection, greater baseline creatinine levels and graft dysfunction concomitant to AMBd therapy and an additional nephrotoxic condition. The 30-day mortality rate was 19.2% and it was significantly associated with disseminated and pulmonary infections, somnolence at admission, high CSF opening pressure, positive CSF India ink, creatinine levels greater than 2.0 mg/dL at admission, graft dysfunction in patients treated with AMBd and an additional nephrotoxic condition and graft loss within 30 days. Graft dysfunction was common in renal transplant recipients with cryptococcosis treated with AMBd. The rate of graft loss rate was high, most frequently in patients with concomitant nephrotoxic conditions. Therefore, the clinical focus should be on the use of less nephrotoxic lipid formulations of amphotericin B in this specific population requiring a polyene induction regimen for treatment of severe cryptococcosis in all health care systems caring for transplantation recipients.

    ABSTRACT Background: Reliable measurement of basal energy expenditure (BEE) in liver transplant (LT) recipients is necessary for adapting energy requirements, improving nutritional status and preventing weight gain. Indirect calorimetry (IC) is the gold standard for measuring BEE. However, BEE may be estimated through alternative methods, including electrical bioimpedance (BI), Harris-Benedict Equation (HBE), and Mifflin-St. Jeor Equation (MSJ) that carry easier applicability and lower cost....

    The rhodococcus is a mycobacterium-like organism which is normally a pathogen in foals. It usually spreads by direct contact or by aerosol from horse faeces and causes pyogranulomatous pulmonary infections. Occasionally, it acts opportunistically to infect immuno-compromised human hosts, most commonly those with the acquired immune deficiency syndrome (AIDS). Here we report a pulmonary infection by Rhodococcus equi in a renal transplant recipient who was successfully treated. The literature o...

    The frequency of malignancy is increasing in kidney transplant recipients. Posttransplant malignancy (PTM) is a major cause of long-term graft survival inhibition. In this study, we evaluated the frequency and prognosis of PTM at our center and examined the efficacy of cancer screening. Between 1972 and 2013, 750 patients were followed-up at our center. Annual physical examinations and screenings were performed to detect PTM. We investigated the detail of two distinctive cancer groups: screening-detected cancers and symptom-detected cancers. Seventy-seven PTM were identified during the follow-up period. The mean age at the initial PTM detection was 43.6 ± 12.8 years. The mean interval from transplantation to cancer diagnosis was 134.5 ± 11.3 months. Among the 77 patients, posttransplant lymphoproliferative disease (PTLD) was the most common cancer (19.5%, 15/77), followed by renal cell carcinoma (15.6%, 12/77). Of the cancer cases, 46.8% (36/77) were detected via screening. The most frequently screening-detected cancer was renal cell carcinoma of the native kidney and breast cancer (22.2%, 8/36). However, it was difficult to detect PTLD, urothelial carcinoma, and colorectal cancer via screening. Interestingly, Cox proportional regression analyses revealed nonscreened recipients to be a significant prognostic factor for PTM (P kidney transplant recipients. These findings support the provision of long-term appropriate screening for kidney transplant recipients. © 2015 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    The image quality and optimal reconstruction interval for coronary arteries in heart transplant recipients undergoing non-invasive dual-source computed tomography (DSCT) coronary angiography was evaluated. Twenty consecutive heart transplant recipients who underwent DSCT coronary angiography were included (19 male, one female; mean age 63.1±10.7 years). Data sets were reconstructed in 5% steps from 30% to 80% of the R-R interval. Two blinded independent observers assessed the image quality of each coronary segments using a five-point scale (from 0 = not evaluative to 4=excellent quality). A total of 289 coronary segments in 20 heart transplant recipients were evaluated. Mean heart rate during the scan was 89.1±10.4 bpm. At the best reconstruction interval, diagnostic image quality (score ≥2) was obtained in 93.4% of the coronary segments (270/289) with a mean image quality score of 3.04± 0.63. Systolic reconstruction intervals provided better image quality scores than diastolic reconstruction intervals (overall mean quality scores obtained with the systolic and diastolic reconstructions 3.03±1.06 and 2.73±1.11, respectively; P<0.001). Different systolic reconstruction intervals (35%, 40%, 45% of RR interval) did not yield to significant differences in image quality scores for the coronary segments (P=0.74). Reconstructions obtained at the systolic phase of the cardiac cycle allowed excellent diagnostic image quality coronary angiograms in heart transplant recipients undergoing DSCT coronary angiography.

    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

    Severe alcohol use is recognized as a major public health concern, even though light to moderate alcohol use might have beneficial effects on health. Alcohol use has been studied to some extent in solid organ transplant populations, yet evidence is lacking on alcohol use and its correlates in the renal transplant population. The aim of this study was therefore to determine the prevalence, severity and correlates of alcohol use in renal transplant recipients. This cross-sectional study is a secondary analysis of the Supporting Medication Adherence in Renal Transplantation (SMART) study. Alcohol use was assessed by patient's self-report. At risk and binge drinkers were classified using World Health Organization criteria. The following correlates of alcohol use were explored: adherence with immunosuppression (Siegal questionnaire; electronic monitoring), smoking, coping style (UCL), depressive symptomatology (BDI) and busyness/routine in life style (ACQ Busyness Scale). Two hundred and eighty-four patients were included in this analysis, 58.1% male, with a mean age of 54 yr (range 20-84) and a median of seven (interquartile ranges [IQR] 8) yr post-transplantation. A total of 52.8% of study participants reported to drink alcohol at least once a week. Two hundred and eighty of 284 subjects (98.5%) were drinking at low risk, four at moderate risk (1.5%). None of the participants were drinking severely. Correlates of alcohol use were male gender and being professionally active. Alcohol use is less prevalent in renal transplant recipients than in the general population. Severe alcohol use does not seem to represent a serious problem in renal transplant patients.

    There is a paucity of data regarding the complications in kidney transplant patients who may require intensive care unit (ICU) management, despite being the most common solid organ transplant worldwide. To identify the main reasons for ICU admission and to determine the factors associated with hospital mortality in kidney transplant recipients. This single-center retrospective cohort study was conducted between September 2013 and June 2014, including all consecutive kidney transplant patients requiring ICU admission. We collected data on patient demographics, transplant characteristics, clinical data, and prognostic scores. The independent determinants of hospital mortality were identified by multiple logistic regression analysis. We also assessed the performance of Simplified Acute Physiology Score 3 (SAPS 3) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores. We analyzed data from 413 patients, the majority of whom were admitted late after renal transplantation (1169 days; 63-3003 days). The main reason for admission was sepsis (33.2%), followed by cardiovascular disease (16%). Age (odds ratio [OR] 1.05, confidence interval [CI], 1.01-1.09), SAPS 3 score (OR 1.04, CI, 1.01-1.08), the need for mechanical ventilation (OR 26.47, CI, 10.30-68.08), and vasopressor use (OR 3.34, CI, 1.37-8.13) were independently associated with hospital mortality. The performance of SAPS 3 and APACHE II scores was poor in this population and overestimated the mortality rates. Sepsis was the main reason for ICU admission in kidney transplant recipients, followed by cardiovascular disease. Age and disease severity were associated with hospital mortality.

    Critical illness polyneuropathy and myopathy are multifaceted complications that follow severe illnesses involving the sensorimotor axons and proximal skeletal muscles. These syndromes have rarely been reported among renal transplant recipients. In this paper, we report a case of acute quadriplegia caused by necrotizing myopathy in a renal transplant recipient with severe pneumonia. The muscle strength in the patient's extremities improved gradually after four weeks of comprehensive treatment, and his daily life activities were normal a year after being discharged.

    Assessment of right ventricular (RV) function using conventional echocardiography might be inadequate as the radial motion of the RV free wall is often neglected. Our aim was to quantify the longitudinal and the radial components of RV function using three-dimensional (3D) echocardiography in heart transplant (HTX) recipients. Fifty-one HTX patients in stable cardiovascular condition without history of relevant rejection episode or chronic allograft vasculopathy and 30 healthy volunteers were enrolled. RV end-diastolic (EDV) volume and total ejection fraction (TEF) were measured by 3D echocardiography. Furthermore, we quantified longitudinal (LEF) and radial ejection fraction (REF) by decomposing the motion of the RV using the ReVISION method. RV EDV did not differ between groups (HTX vs control; 96 ± 27 vs 97 ± 2 mL). In HTX patients, TEF was lower, however, tricuspid annular plane systolic excursion (TAPSE) decreased to a greater extent (TEF: 47 ± 7 vs 54 ± 4% [-13%], TAPSE: 11 ± 5 vs 21 ± 4 mm [-48%], P < .0001). In HTX patients, REF/TEF ratio was significantly higher compared to LEF/TEF (REF/TEF vs LEF/TEF: 0.58 ± 0.10 vs 0.27 ± 0.08, P < .0001), while in controls the REF/TEF and LEF/TEF ratio was similar (0.45 ± 0.07 vs 0.47 ± 0.07). Current results confirm the superiority of radial motion in determining RV function in HTX patients. Parameters incorporating the radial motion are recommended to assess RV function in HTX recipients. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The aim of this study was to determine whether detection of β-HPV gene products, as defined in epidermodysplasia verruciformis skin cancer, could also be observed in lesions from kidney transplant recipients alongside the viral DNA. A total of 111 samples, corresponding to 79 skin lesions abscised from 17 kidney transplant recipients, have been analyzed. The initial PCR analysis demonstrated that β-HPV-DNA was highly present in our tumor series (85%). Using a combination of antibodies raised against the E4 and L1 proteins of the β-genotypes, we were able to visualize productive infection in 4 out of 19 actinic keratoses, and in the pathological borders of 1 out of 14 squamous cell carcinomas and 1 out of 31 basal cell carcinomas. Increased expression of the cellular proliferation marker minichromosome maintenance protein 7 (MCM7), that extended into the upper epithelial layers, was a common feature of all the E4-positive areas, indicating that cells were driven into the cell cycle in areas of productive viral infections. Although the present study does not directly demonstrate a causal role of these viruses, the detection of E4 and L1 positivity in actinic keratosis and the adjacent pathological epithelium of skin cancer, clearly shows that β-HPV are actively replicating in the intraepidermal precursor lesions of kidney transplant recipients and can therefore cooperate with other carcinogenic agents, such as UVB, favoring skin cancer promotion.

    Full Text Available Background and Objectives: Immunosuppressed individuals are at particularly increased risk for human papilloma virus-related infections. The primary objective of our study is to determine if there are any adverse effects associated with high-dose cimetidine treatment. A secondary objective is to report our experience with cimetidine in the treatment of cutaneous warts in pediatric heart transplant recipients. Methods and Results: This was a retrospective observational study. A total of 8 pediatric heart transplant recipients diagnosed with multiple recalcitrant warts were the subject of the study. All patients were treated with cimetidine (30–40 mg/kg/day in two divided doses for 3 to 6 month durations. All patients had complete resolution of their lesions except 1 patient who had no clinical improvement. Of these 8 patients, one had recurrence of warts at one year follow-up, which resolved with restarting cimetidine therapy. One patient who had only 3 months of cimetidine therapy had immediate relapse after cimetidine was stopped. None of them had significant change in their tacrolimus trough, serum creatinine, and alanine transaminase levels. No adverse events were reported except one patient experienced mild gynecomastia. Conclusion: Cimetidine can be a safe and alternative treatment option for multiple warts in pediatric heart transplant recipients.

The study included 8 renal transplant recipients. In these patients immediately after the operation was performed the coupled plasma fi ltration adsorption with hemofiltration using a cartridge Mediasorb to reduce the severity of reperfusion injury. We have found that during this extracorporeal blood correction procedure there was statistically not signifi cant decrease of tacrolimus blood concentration. However, concentration of tacrolimus remained in the therapeutic range even after the procedure and it was not signifi cantly different from the control point С0.Conclusion. Coupled plasma fi ltration adsorption is safe in renal transplant recipients and has no signifi cant impact on tacrolimus blood concentration. However, the downward trend in the concentration of tacrolimus in the course of these procedures, especially in continuous or semicontinuous mode, as well as in patients with low hematocrit and hypoalbuminemia, requires individual monitoring.

    Human metapneumovirus (hMPV) is a recently discovered paramyxovirus that is known to cause respiratory tract infections in children and immunocompromised individuals. Given the difficulties of identifying hMPV by conventional culture, molecular techniques could improve the detection of this virus in clinical specimens. In this study, we developed a real-time reverse transcription-PCR (RT-PCR) assay designed to detect the four genetic lineages of hMPV. This assay and a commercial real-time nucleic acid sequence-based amplification (NASBA) assay (bioMérieux, Durham, NC) were used to determine the prevalence of hMPV in 114 immunosuppressed asymptomatic and symptomatic lung transplant recipients and 232 pediatric patients who were being evaluated for pertussis. hMPV was detected in 4.3% of the immunosuppressed lung transplant recipients and in 9.9% of children evaluated for pertussis. Both RT-PCR and NASBA assays were efficient in detection of hMPV infection in respiratory specimens. Even though hMPV was detected in a small number of the lung transplant recipients, it was still the most prevalent etiologic agent detected in patients with respiratory symptoms. In both of these diverse patient populations, hMPV infection was the most frequent viral respiratory tract infection identified. Given our findings, infection with hMPV infection should be determined as part of the differential diagnosis of respiratory illnesses.

    Cardiovascular complications after transplantation are an important cause of non-transplant-related deaths. Depression and anxiety are not unusual among organ recipients. Physical activity reduces cardiovascular risk and promotes a sensation of well-being. The aims of the study were to examine how exercise affects psychological well-being sensation in organ recipients and to describe the physician's role in promoting and controlling safe sport training in transplanted patients. A descriptive study was conducted. A questionnaire was answered by participants of the "2012 Latin American Transplant Games." One hundred sixty-six organ recipients completed the questionnaire. Eleven percent heard about the transplant games from a physician. Seventy percent had not received a proper medical pre-competitive evaluation. Only 39% trained in a supervised manner and 53% had experienced some kind of sport-related injury. Self-perception of global health was reported as excellent by 19.75%, very good by 43.95%, good by 30.67%, and regular or poor by 5.73%. An excellent or very good health perception was reported by 47.8% of those who practiced only one kind of sport versus 71.5% of those who practiced more than one sport and by 89.6% of those who performed isometric activity versus 59.3% of those who did not perform isometric activity. Diversity of practiced sports and isometric activity are associated with a better self-reported health condition. Most participants had not received a proper medical pre-competitive evaluation; they trained in an unsupervised manner, and injuries were common. Copyright © 2016 Elsevier Inc. All rights reserved.

    Acute hepatic encephalopathy has significant morbidity and mortality in liver transplant recipients unless it is promptly treated. We evaluated the brain magnetic resonance (MR) imaging findings associated with acute hepatic encephalopathy in transplant recipients. We retrospectively reviewed the clinical and imaging data and outcomes of twenty-five liver transplant patients (16 male; mean age, 49.3 years) with clinically diagnosed acute hepatic encephalopathy and forty liver transplant patients (20 males; mean age, 45.5 years) without neurological symptoms suggestive of hepatic encephalopathy at our institution. Bilateral symmetric hyperintensities of the insular cortex and cingulate gyrus were observed in twenty-one patients (84.00%), bilateral symmetric extensive increased cortical signal intensity (involving two or more regions) was observed in 72.00% of the patients, leptomeningeal enhancement in 73.68%, and visualization of prominent venules in 52.00%. The most common symptom at diagnosis was rigidity (n = 14), and the plasma ammonia levels ranged from 68.63 to 192.16 μmol/L. After active treatment, 17 patients gradually recovered, four patients suffered from mild or moderate neurologic deficits, and four patients with widespread brain edema died. The specific brain MR imaging features were bilateral symmetric increased cortical signal intensity, especially in the insular cortex and cingulate gyrus, leptomeningeal enhancement, visualization of the prominent venules, and widespread brain edema. These features may indicate poor prognosis and should alert radiologists to the possibility of acute hepatic encephalopathy in liver transplant recipients and encourage clinicians to prepare appropriate treatment in advance.

    Epstein-Barr virus (EBV) infection may result in a spectrum of diseases in recipients of transplant. The aim of this study is to investigate the incidence, clinical characteristics, and prognosis of the spectrum of EBV-associated diseases in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 263 recipients undergoing allo-HSCT were prospectively enrolled. The blood EBV-DNA loads were regularly monitored by quantitative real-time polymerase chain reaction. The 3-year cumulative incidence of total EBV-associated diseases, posttransplantation lymphoproliferative diseases (PTLD), EBV fever, and EBV end-organ diseases (pneumonia, encephalitis/myelitis, and hepatitis) were 15.6%±2.5%, 9.9%±2.0%, 3.3%±1.3%, and 3.3%±1.2% (2.2%±1.0%, 1.6%±0.8%, and 0.9%±0.6%), respectively. Fever was the most common symptom of EBV-associated diseases. Patients with PTLD had better response rate to rituximab-based treatments compared with those with EBV end-organ diseases (including PTLD accompanied by EBV end-organ diseases) (P=0.014). The 3-year overall survival was 37.3%±13.7%, 100.0%, and 0.0%±0.0% in patients with PTLD, EBV fever, and EBV end-organ diseases (P=0.001). EBV-associated diseases other than PTLD are not rare in the recipients of allo-HSCT. The clinical manifestations of EBV end-organ diseases are similar to PTLD. EBV end-organ diseases had poorer response to rituximab-based therapy compared with PTLD.

    Glomerular filtration rate (GFR) measurement is a major issue in kidney transplant recipients for clinicians. GFR can be determined by estimating the plasma clearance of iohexol, a nonradiolabeled compound. For practical and convenient application for patients and caregivers, it is important that a minimal number of samples are drawn. The aim of this study was to develop and validate a Bayesian model with fewer samples for reliable prediction of GFR in kidney transplant recipients. Iohexol plasma concentration-time curves from 95 patients were divided into an index (n = 63) and a validation set (n = 32). Samples (n = 4-6 per patient) were obtained during the elimination phase, that is, between 120 and 270 minutes. Individual reference values of iohexol clearance (CL(iohexol)) were calculated from k (elimination slope) and V (volume of distribution from intercept). Individual CL(iohexol) values were then introduced into the Bröchner-Mortensen equation to obtain the GFR (reference value). A population pharmacokinetic model was developed from the index set and validated using standard methods. For the validation set, we tested various combinations of 1, 2, or 3 sampling time to estimate CL(iohexol). According to the different combinations tested, a maximum a posteriori Bayesian estimation of CL(iohexol) was obtained from population parameters. Individual estimates of GFR were compared with individual reference values through analysis of bias and precision. A capability analysis allowed us to determine the best sampling strategy for Bayesian estimation. A 1-compartment model best described our data. Covariate analysis showed that uremia, serum creatinine, and age were significantly associated with k(e), and weight with V. The strategy, including samples drawn at 120 and 270 minutes, allowed accurate prediction of GFR (mean bias: -3.71%, mean imprecision: 7.77%). With this strategy, about 20% of individual predictions were outside the bounds of acceptance set at ± 10

    This study examined health promotion behaviours of kidney transplant recipients, 1-5 years after transplant and identified the risk factors predicting non-adherence to post-transplant recommendations. Non-adherence to health care recommendations and health promotion behaviours is one of the top three reasons for graft loss following kidney transplantation. A cross-sectional study. Kidney transplant recipients (n=101) in southern Taiwan completed a self reported survey, the Kidney Transplant Health Promotion Behavior and Healthcare Provider Support survey. Kidney transplant patients had better adherence with medication and least adherence with regular exercise health promotion behaviours. Age, post kidney transplant time, health care provider support and financial satisfaction accounted for 37·2% of the explained variance in monitoring and management for rejection and infection. Marital status, post kidney transplant time and gender accounted for 16·2% of the explained variance in infection prevention. Age was the sole predictor of exercise (odds ratio=1·08, p=0·025). Health promotion behaviours declined with time and perceived healthcare provider support decreased at the third (p=0·04) post kidney transplant year. In this study, young, single, males were identified as requiring specific strategies to improve post kidney transplant health promotion behaviours. The need for health promotion must be continually reinforce by healthcare providers throughout the lifespan of a kidney transplant recipient. Understanding the changes of health behaviours of post kidney transplant recipients and their risk factors, healthcare providers can be more aware of the needs of patients in maintaining health promotion behaviours. © 2011 Blackwell Publishing Ltd.

    Full Text Available Introduction. One of the current tasks of transplantology is to overcome «graft-host» immune confl ict. Partially this confl ict is caused by the presence of circulating pre-existing antibodies. Highly sensitized patients have a greater risk of rejection and subsequent graft loss. There are several methods to remove the antibodies, one of which is a double fi ltration plasmapheresis (DFPF. This report presents our experience of DFPF in recipients of high immunologic risk.Aim: to compare the effectiveness of traditional and double filtration plasmapheresis in desensitization of patients with high risk of immunological complications.Methods. The study included 30 patients after kidney transplantation. All patients were classifi ed as high-immunologic risk group. In 15 patients of study group we performed DFPF, in 15 patients of comparison group – traditional plasmapheresis. We monitored the immune status: markers of humoral immunity activation – IgG, IgM, IgA before and after the procedures. DFPF procedure was performed on OctoNova (MeSys, Germany with a plasmafi lter and plasma components separator. Protocol biopsies were performed on days 30 and 90.Results. The concentration of antibodies may be effectively reduced with DFPF. Total IgM and IgG antibodies were reduced by 30–55% of the original level. There was a less albumin loss in case of DFPF application. There is 1 patient with antibody-mediated rejection with graft dysfunction in study group. There are no signs of rejection in 30- and 90-day biopsy in study group. But there were three patients with subclinical antibody-mediated rejection in the comparison group.Conclusion. DFPF can safely and effectively reduce the high titers of antibodies that are responsible for humoral rejection of renal allograft. Reduction of antibodies in sensitized patients immediately after transplantation may improve graft function.

    Full Text Available We retrospectively reviewed the records of 273 renal transplant recipients who received allograft transplants between 1994 and 2004 and recorded the incidence and types of de novo malignancies that developed in these patients. The study was carried out at the Al-karama and Al-rasheed kidney transplant centers in Baghdad, Iraq. A total of 16 patients developed malignancies. The tumors included Kaposi′s sarcoma (KS in eight patients, squamous cell carcinoma (SCC in four, basal cell carcinoma (BCC in two and both renal cell carcinoma of the allograft and brain tumor in one patient. Thus, KS was the most common malignancy encountered in our series, with a prevalence of 2.9%, followed by SCC observed in 1.5% and BCC found in 0.7 % of the patients. The average latency period between transplantation and development of malignancy was 6.5 months for KS, 3.0 months for SCC and 8.5 months for BCC. To our knowledge, this is the first long-term follow-up study for malignant complications identified in kidney recipients in Iraq.

    Organ transplant recipients under immunosuppressive therapy have a highly increased risk of acquiring unusual opportunistic infections. Diagnosis of the etiology of infection may be difficult in clinical manifestations, which need further histological and biological investigations. We recently treated a male renal transplant recipient with a cutaneous phaeohyphomycosis due to Alternaria species. The diagnosis was based on microscopy and culture of the skin lesions. Treatment with oral itraconazole for 5 weeks was ineffective, then clinical improvement was achieved by combination of amphotericin B wet-packing and systemic antifungal therapy with oral voriconazole. Alternaria species are ubiquitous plant-inhabiting saprobes, which are increasingly associated with opportunistic phaeohyphomycosis in immunocompromised individuals. To the best of our knowledge, this is the second case report noting sporotrichoid pattern as the manifestation of cutaneous alternariosis. In this context, we reviewed recent renal-transplant-related cutaneous alternariosis reported in the English-language literature during 1995 to 2011 to summarize its clinical features and outcomes, and to guide clinicians in the care of kidney transplant patients with cutaneous alternariosis.

    Full Text Available Cyclosporine is the main immunosuppressive drug used for renal transplant reci-pients in order to prevent transplant rejection. Although the drug has increased the survival of patients and grafted organ, it has some side effects independent of its effect on the immune system. This study was done to evaluate the effect of cyclosporine on serum Mg level and its metabolic side effects in renal allograft patients. 157 (62 female and 95 male renal transplant recipients treated w
