    Hyperparathyroidism, a frequent complication of chronic kidney disease, persists after renal transplant. Our aims were to examine the status of parathyroid hormone levels and to determine the clinical and biochemical risk factors of persistent hyperparathyroidism after transplant. Our study included 44 pediatric renal transplant recipients with stable graft function. Median follow-up after transplant was 17.5 months (range, 12-126 mo). Patients did not receive routine vitamin D or calcium supplements after transplant, and none had undergone previous parathyroidectomy. Bone mineral densitometry of the lumbar spine was measured. Fifteen patients (34%) had parathyroid hormone levels greater than 70 pg/mL (normal range, 10-70 pg/mL). Duration of dialysis before transplant was longer in patients with persistent hyperparathyroidism. Mean serum bicarbonate levels were significantly lower in patients with persistent hyperparathyroidism than in patients without persistent hyperparathyroidism after transplant. A significant negative correlation was noted between parathyroid hormone level and serum bicarbonate level. Another significant negative correlation was shown between parathyroid hormone level and z score. We found that persistent hyperparathyroidism is related to longer dialysis duration, lower serum bicarbonate level, and lower z score. Pretransplant dialysis duration is an important predictor of persistent hyperparathyroidism. Early identification of factors that contribute to persistent hyperparathyroidism after transplant could lead to treatment strategies to minimize or prevent its detrimental effects on bone health and growth in pediatric transplant recipients.

    Secondary hyperparathyroidism persists after renal transplantation in a substantial number of patients. Primary hyperparathyroidism and secondary hyperparathyroidism are both associated with abnormalities in glucose metabolism, such as insufficient insulin release and glucose intolerance. The association of hyperparathyroidism and diabetes after renal transplantation has, as far as we know, not been studied. Our aim was to investigate whether hyperparathyroidism is associated with new-onset diabetes mellitus after transplantation (NODAT) during the first year posttransplantation. In a retrospective study, we analyzed data on patient characteristics, treatment details, and parathyroid hormone (PTH) in 245 adult nondiabetic patients who underwent renal transplantation between January 2000 and June 2011. The first year cumulative incidence of NODAT was 15%. The first serum PTH value after transplantation was above normal range in 74% of the patients. In multiple logistic regression analysis, PTH levels above twice normal range (>13.80 pmol/L) were significantly associated with NODAT (odds ratio [OR], 4.25; 95% confidence interval [CI], 1.13-15.92; P = .03) compared with PTH within normal range (≤6.9 pmol/L). Age between 45 and 65 years (OR, 2.80; 95% CI, 1.07-7.36; P = .04) compared with age hyperparathyroidism and NODAT in the first year after renal transplantation. Both conditions are common and have a negative impact on graft and patient survivals. Our results should be confirmed in prospective studies. Copyright © 2014 Elsevier Inc. All rights reserved.

    Hyperparathyroidism is reported in 10% to 66% of renal transplant recipients (RTR). The influence of persisting hyperparathyroidism on long-term clinical outcomes in RTR has not been examined in a large prospective study. We investigated the association between baseline parathyroid hormone (PTH) levels and major cardiovascular events, renal graft loss, and all-cause mortality by Cox Proportional Hazard survival analyses in 1840 stable RTR derived from the Assessment of LEscol in Renal Transplantation trial. Patients were recruited in a mean of 5.1 years after transplantation, and follow-up time was 6 to 7 years. Significant associations between PTH and all 3 outcomes were found in univariate analyses. When adjusting for a range of plausible confounders, including measures of renal function and serum mineral levels, PTH remained significantly associated with all-cause mortality (4% increased risk per 10 units; P=0.004), and with graft loss (6% increased risk per 10 units; PHyperparathyroidism is an independent, potentially remediable, risk factor for renal graft loss and all-cause mortality in RTR.

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

    Parathyroidectomy (PTX) is the only curative treatment for tertiary hyperparathyroidism (3HPT). With the introduction of calcimimetics (cinacalcet), PTX can sometimes be delayed or avoided. The purpose of this study was to determine the current incidence of utilization of PTX in patients with posttransplant 3HPT with the advent of cinacalcet. We evaluated renal transplant patients between January 1, 2004, and June 30, 2012, with a minimum of 24 months follow-up who had persistent allograft function. Patients with an increased serum level of parathyroid hormone (PTH) at 1 year after successful renal transplantation with normocalcemia or hypercalcemia were defined as having 3HPT. A multivariate logistic regression model was constructed to determine factors associated with undergoing PTX. We identified 618 patients with 3HPT, only 41 (6.6%) of whom underwent PTX. Patients with higher levels of serum calcium (P < .001) and PTH (P = .002) posttransplant were more likely to be referred for PTX. Importantly, those who underwent PTX had serum calcium and PTH values distributed more closely to the normal range on most recent follow-up. PTX was not associated with rejection (P = .400) or with worsened allograft function (P = .163). PTX seems to be underused in patients with 3HPT at our institution. PTX is associated with high cure rates, improved serum calcium and PTH levels, and is not associated with rejection. Copyright © 2016 Elsevier Inc. All rights reserved.

    Parathyroid glands (PG) are rarely analyzed in renal transplant (RTX) patients. This study analyzes comparatively PG of RTX and end-stage renal disease (ESRD) patients. The clinical part of the study evaluates if total parathyroidectomy with autotransplantation (TPT+AT) treats appropriately hypercalcemic hyperparathyroidism in RTX patients. TPT+AT was performed in 15 of 23 RTX and 21 of 27 ESRD patients. Remaining patients underwent less-than-total PT. Volume and stage of hyperplasia were determined from 86 PG of RTX and 109 PG of ESRD patients. Patients were categorized according to the presence of small PG (volume hyperparathyroidism were evaluated 2 years after PT in RTX patients. PG of RTX patients were significantly smaller, but similar hyperplastic in comparison to PG of ESRD patients. Small PG were more frequent in RTX than in ESRD patients (19% vs 6%) and mainly graded normal or diffuse hyperplastic (94%). Forty-seven percent of RTX, but only 14% of ESRD, patients receiving a total PT possessed ≥1 small PG (P hyperparathyroidism. However, TPT+AT caused permanent hypocalcemia in 50% of RTX patients without small PG and even in 83% of RTX patients with small PG. All RTX patients receiving less-than-total PT were normocalcemic at 2-year follow-up. Logistic regression revealed a 10.7 times greater risk of permanent hypocalcemia in RTX patients with small PG receiving TPT+AT compared with RTX patients without small PG receiving TPT+AT or RTX patients undergoing less-than-total PT. Surgeons performing PT should be aware of the high frequency of small and less diseased PG in RTX patients. In this context, TPT+AT might overtreat hypercalcemic hyperparathyroidism in RTX patients, especially when small PG are present. Copyright © 2014 Mosby, Inc. All rights reserved.

    2016-01-01

    Renal hyperparathyroidism (rHPT) is a common complication of chronic kidney disease characterized by elevated parathyroid hormone levels secondary to derangements in the homeostasis of calcium, phosphate, and vitamin D. Patients with rHPT experience increased rates of cardiovascular problems and bone disease. The Kidney Disease: Improving Global Outcomes guidelines recommend that screening and management of rHPT be initiated for all patients with chronic kidney disease stage 3 (estimated glomerular filtration rate, < 60 mL/min/1.73 m(2)). Since the 1990s, improving medical management with vitamin D analogs, phosphate binders, and calcimimetic drugs has expanded the treatment options for patients with rHPT, but some patients still require a parathyroidectomy to mitigate the sequelae of this challenging disease.

  10. Use of Cinacalcet in the treatment of persistent hyperparathyroidism post-renal transplant. A single center experience in Argentina

    2017-06-01

    Full Text Available Introduction: Renal transplant (RTx is associated with the decrease in serum parathyroidhormone (PTH levels. The persistence of high PTH levels associated to hypercalcemia is suggestive of persistent hyperparathyroidism (pHPT. pHPT is a risk factor for vascular calcifications, bone loss, and graft survival. Cinacalcet acts on the calcium sensing receptor increasing their activation by ionic Ca, reducing serum PTH, Ca, and phosphate (P levels. The objective of this study was to evaluate the efficacy and safety of cinacalcet in RTx patients with pHPT and hypercalcemia. Methods: We performed a retrospective, observational study in 14 RTx patients who received cinacalcet for at least 3 months as part of the pHPT treatment. Results: Pre-cinacalcet iPTH levels were 159 ± 70 pg/ml; after one month it was 151 ± 110 pg/ml, 150 ± 96 pg/ml at three months, 142 ± 64 at six months and 139 ± 75 pg/ml after one year. The decrease in the iPTH was not significant. The serum Ca significantly decreased from 11.3 ± 0.8 to 10.0 ± 0.8 mg/dl after one month (p<0.001 keeping serum levels stable after three (10.2 ± 1.0, six (10.3 ± 0.5, and twelve (10 ± 0.4 months. P was 2.7 ± 0.79 mg/dl at the beginning of treatment, keeping their levels stable after 3, 6, and 12 months. The average dose of cinacalcet at the beginning was 30 mg increasing in a non-significant way on the 3rd month to 32 ± 12 mg/d, on the 6th month to 40 ± 22 mg/d, and on the 12th month to 41.6 ± 18 mg/d. Conclusion: In this small cohort of patients with pHPT and hypercalcemia, cinacalcet was effective in reducing serum Ca levels (p<0.001, but not iPTH.

    Secondary hyperparathyroidism (sHPT) is a major complication for patients with end-stage renal disease on long-term hemodialysis or peritoneal dialysis. When the disease is resistant to medical treatment, patients with severe sHPT are typically referred for parathyroidectomy (PTx), which usually improves biological parameters as well as clinical signs and symptoms. Unfortunately, early surgical failure with persistent disease may occur in 5%–10% of patients and recurrence reaches 20%–30% at 5 years. Presently, the use of parathyroid scintigraphy in sHPT is usually limited to the management of surgical failures after initial PTx. This review describes the strengths and limitations of typical 99mTc-sestamibi imaging protocols, and highlights the potential benefits of using parathyroid scintigraphy in the initial workup of surgical patients.

    Different surgical strategies are used to treat medical refractory renal hyperparathyroidism. Our preferred choice in patients with moderate secondary hyperparathyroidism (SHPT) and in patients with low compliance with medical treatment is to leave a very small parathyroid remnant in situ: we name this operation "near total parathyroidectomy" (ntPTX). We report here our results with this technique. Retrospective study [2001-2015] of all patients submitted to ntPTX in a single centre. Forty-seven patients were submitted to ntPTX (32 males) aged 47.3 years. Follow-up time is 8.5 years. Thirty-five patients (74%) are alive, 12 are dead. One patient in this series had a functioning renal transplant at time of ntPTX (tertiary hyperparathyroidism), and other 27 subsequently received a renal transplantation (RTx) after ntPTX (still functioning at last follow-up or at death in 19). Amongst the 35 current survivors, the renal graft is functioning in 16 (45.7%). Parathyroid hormone (PTH) at follow-up was 116.1±135.5 pg/mL and calcium 8.6±0.9 mg/dL. Among patients with a functioning RTx PTH was 83 pg/mL and calcium 8.7 mg/dL. There was no persistent disease, and 3 patients (6.4%) had a relapse of hyperparathyroidism at follow-up. ntPTX is associated to very satisfying rates of normal parathyroid function and of relapse of hyperparathyroidism (6.4%) at long term, either in case of RTx or of maintenance hemodialysis: the concept of "small amount" remnant represents a valuable choice for patients undergoing PTX with a realistic chance of receiving a RTx.

Renal excretion of calcium varied differently − in two patients increased gradually, without exceeding the physiological norm, and in one − remained stable. Gene- ral pattern in the dynamics of serum concentration and urinary excretion of phosphorus was not observed. Renal graft function remained stable − GFR 46–76 ml/min. BMD of the distal forearm, femoral neck and lumbar spine in two patients remained the same, in one − increased by 14, 6 and 7%. Adverse events were absent. Conclusion. Application of cinacalcet is promising for the correction of HPT in renal transplant recipients.

    Tertiary hyperparathyroidism (tHPT) usually regresses after renal transplantation. Persistent tHPT after successful renal transplantation may require parathyroidectomy (PTX). PTX has been reported to be associated with deterioration of renal function and graft survival. We retrospectively analyzed 794 kidney transplants performed at our center with at least 3 years of follow-up to examine the effect of PTX on the renal function and graft survival. Forty-nine of the 794 renal transplant recipients were diagnosed with hyperparathyroidism (HPT) before transplant. Nineteen of 49 patients had persistent tHPT and underwent PTX after kidney transplants. Patients with HPT and non-HPT had similar 3-year graft survival (88% versus 84%, P = 0.51). PTX was associated with a decreased glomerular filtration rate at 3 years (44.7 ± 20.0 versus 57.7 ± 23.7 mL/min, P = 0.04); however, there was no statistical difference in the 3-year graft survival (71% versus 88%, P = 0.06). PTX in renal transplant recipients seems to be a safe and effective therapy for persistent tHPT. PTX may be associated with worsening glomerular filtration rate, but it may not be associated with significantly decreased long-term graft survival. PMID:20234299

    Persistent hyperparathyroidism after kidney transplantation is related to graft function, but pre-transplantation risk factors of persistent hyperparathyroidism have not been evaluated in detail. We enrolled 86 patients who had undergone kidney transplantation between 2008 and 2014. Nine patients showed persistent hyperparathyroidism characterized by the following: 1) serum parathyroid hormone levels >65 pg/mL and serum calcium levels >10.5 mg/dL at 1 year after kidney transplantation; 2) parathyroidectomy after kidney transplantation; and 3) reintroduction of cinacalcet after kidney transplantation. Compared with other patients, these 9 patients had significantly longer duration of dialysis therapy (186 ± 74 mo vs 57 ± 78 mo) and more frequent treatment with cinacalcet during dialysis (89% vs 12%). Multivariate analysis showed that dialysis vintage, calcium phosphate products, and cinacalcet use before kidney transplantation were independent risk factors of persistent hyperparathyroidism after kidney transplantation. A receiver operating characteristic curve showed 72 months as the cutoff value of dialysis vintage and 55 as the cutoff value of calcium phosphate products. In conclusion, dialysis vintage >6 years, calcium phosphate products >55 (mg/dL) 2 , and cinacalcet use before kidney transplantation are strong predictors of persistent hyperparathyroidism. High-risk patients should be evaluated for parathyroid enlargement, and parathyroidectomy must be considered before kidney transplantation. Copyright © 2016 Elsevier Inc. All rights reserved.

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

    Twenty-seven patients on chronic haemodialysis and with secondary hyperparathyroidism underwent subtotal parathyroidectomy during the period 1985-1989. The operation was indicated by severe clinical symptoms and evidence of radiological abnormalities not responsive to conservative treatment (low phosphorus diet, phosphate binding substances, oral calcium and vitamin D). If despite intensive medical management, inadequate control of parathyroid hyperplasia continues surgical intervention becomes necessary. Ultra-sonography was performed pre-operatively in all 27 cases and detected 42 of 99 glands (42.5 per cent). Also scintigraphy was carried out in every patient but it gave a relatively low detection rate (24.5 per cent). Surgery was followed by improvement in 20 patients and progression of hyperparathyroidism in seven cases. Three of the seven patients failed to improve after subtotal parathyroidectomy, necessitating a re-intervention; the remaining four responded sufficiently to medical therapy. From our experience we conclude that subtotal parathyroidectomy for renal hyperparathyroidism is recommended.

    Despite being considered a high risk procedure, renal transplantation has been recognized for more than 20 years as the best therapeutic option for children with end-stage renal disease since it is superior than any available dialytic procedure in improving the neuropsychological development and the quality of life. Today pediatric patients have similar graft survival than adults, and 10 year-old children or less have better outcome than any other age group. These remarking results are due to the development of specialized pediatric transplant centers and research programs, improvement in the selection and preparation of donors and recipients, refinement of the surgical technique and the use of new immunossupressive drugs.

    Full Text Available Obiectives: To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. Patients and Methods: From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10% of them developed urinary calculi and were referred at our institution. Their mode of presentation, investigation and treatment were recorded. Results: Seven had renal and 3 ureteral calculi. Urolithiasis was incidentally discovered on routine ultrasound in 6 patients, 1 presented with oliguria, 1 with anuria and acute renal failure and in 2 urolithiasis was found at removal of the ureteral stent. Nephrostomy tube was placed in 5 patients. Hypercalcemia with hyperparathyroidism (HPT was present in 5 patients and hyperuricemia in 3. Two patients were primary treated by shock wave lithotripsy (SWL and one of them was stone-free after two sessions. Two patients, one with multiple pielocaliceal calculi and the other with staghorn calculus in the lower calyx, were treated with percutaneous nephrolitothotomy (PCNL. Three patients were treated by ureteroscopy (URS and in one of them two treatments were carried out. One patient had calculus impacted in the uretero-vesical anastomosis and surgical ureterolithotomy with re-do ureterocystoneostomy was performed after failure of URS. Two patients with calculi discovered at removal of the ureteral stent were treated by URS. Conclusions: The incidence of urolithiasis in renal transplantation is uncommon. In the most of patients the condition occurs without pain. Metabolic anomalies and medical treatment after renal transplantation may cause stone formation.

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

    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.

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

    The relationship between hyperparathyroidism and lithiasis is quite known, so the study of parathyroid glands is especially mandatory in the face of relapses. Our objective is to analyze both primary hyperparathyroidism (PHPT) associated with renal lithiasis and the evolution of this condition after parathyroidectomy, as well as to study factors associated with the presence of lithiasis or bone pathology, and carry out a review on bibliography. We describe a retrospective study of a series comprising 287 cases of hyperparathyroidism: 237 of them were primary and the remaining 50, secondary. We have included: sex, age, evolution time and symptoms, diagnostic tests (biochemical, radiological and histological). Factors such as number of episodes prior to diagnosis and treatments were analyzed in patients with symptomatic lithiasis to know whether patients exhibited residual lithiasis after the management of calculi or whether patients underwent episodes after parathyroidectomy, or whether or not they were treated. Statistical analysis was carried out through SPSS 15.0 for Windows. Forty five percent of the patients had suffered lithiasis episodes; 50%, osteopenia/osteoporosis; 23%, musculoskeletal pain; 23%, asthenia and/or depressive syndrome. In 13.5% of cases, diagnosis was supported by the presence of hypercalcemia; no other symptoms were detected. We have analyzed factors that favor or inhibit renal lithiasis formation and compared biochemical parameters from the group of primary hyperthyroidism that exhibited lithiasis (41 patients) with those patients who did not (49). We noted that lithiasis patients showed higher values of calcium, alkaline phosphatase, intact PTH, mean PTH, osteocalcin, and chlorine/phosphate, calciuria and phosphaturia indexes. Student's t test on two independent samples revealed significant statistical differences in calcium levels (plithiasis presented higher values of parathormone, alkaline phosphatase, osteocalcin, and Cl/P and

    Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required. Although rare, case reports are available on extrapulmonary tuberculosis in allograft recipients. Here, we present a 25-year-old kidney transplant recipient who was diagnosed with lymph node tuberculosis under uncommon circumstances but who had a good outcome. This case report illustrates the difficulties in diagnosis of tuberculosis, changes in therapeutic protocols, and prognostic factors and highlights the effects of infectious complications with immunosuppressive therapy in this particular patient population.

  8. Physical Activity and Renal Transplantation

    2014-07-01

    Full Text Available Renal transplantation is burdened by high cardiovascular risk because of increased prevalence of traditional and disease-specific cardiovascular risk factors and, consequently, patients are affected by greater morbidity and mortality. In renal transplanted patients, healthy lifestyle and physical activity are recommended to improve overall morbidity and cardiovascular outcomes. According to METs (Metabolic Equivalent Task; i.e. the amount of energy consumed while sitting at rest, physical activities are classified as sedentary (<3.0 METs, of moderate-(3.0 to 5.9 METs or vigorous-intensity (≥6.0 METs. Guidelines suggest for patients with chronic kidney disease an amount of physical activity of at least 30 minutes of moderate-intensity activity five times per week (min 450 MET-minutes/week. Data on physical activity in renal transplanted patients, however, are limited and have been mainly obtained by mean of non-objective methods. Available data suggest that physical activity is low either at the start or during renal transplantation and this may be associated with poor patient and graft outcomes. Therefore, in renal transplanted patients more data on physical activity obtained with objective, accelerometer-based methods are needed. In the meanwhile, physical activity have to be considered as an essential part of the medical care for renal transplanted recipients.

    Full Text Available Background/Aims: Individuals who reach end-stage kidney disease (CKD5 have a high risk of vascular events that persists even after renal transplantation. This study compared the prevalence and severity of microvascular disease in transplant recipients and patients with CKD5. Methods: Individuals with a renal transplant or CKD5 were recruited consecutively from renal clinics, and underwent bilateral retinal photography (Canon CR5-45, Canon. Their retinal images were deidentified and reviewed for hypertensive/microvascular signs by an ophthalmologist and a trained grader (Wong and Mitchell classification, and for vessel caliber at a grading centre using a computer-assisted method and Knudtson's modification of the Parr-Hubbard formula. Results: Ninety-two transplant recipients (median duration 6.4 years, range 0.8 to 28.8 and 70 subjects with CKD5 were studied. Transplant recipients were younger (pConclusions: Hypertensive/microvascular disease occurred just as often and was generally as severe in transplant recipients and subjects with CKD5. Microvascular disease potentially contributes to increased cardiac events post- transplantation.

    Secondary hyperparathyroidism is a common complication of chronic kidney disease (CKD) that is associated with bone disease, cardiovascular disease and death. Pathophysiological factors that maintain secondary hyperparathyroidism in advanced CKD are well-known, but early mechanisms of the disease that can be targeted for its primary prevention are poorly understood. Diuretics are widely used to control volume status and blood pressure in CKD patients but are also known to have important effects on renal calcium handling, which we hypothesized could alter the risk of secondary hyperparathyroidism. We examined the relationship of diuretic treatment with urinary calcium excretion, parathyroid hormone (PTH) levels and prevalence of secondary hyperparathyroidism (PTH ≥ 65 pg/mL) in a cross-sectional study of 3616 CKD patients in the Chronic Renal Insufficiency Cohort. Compared with no diuretics, treatment with loop diuretics was independently associated with higher adjusted urinary calcium (55.0 versus 39.6 mg/day; P diuretics. However, coadministration of thiazide and loop diuretics was associated with blunted urinary calcium (30.3 versus 55.0 mg/day; P diuretics alone. Loop diuretic use was associated with greater calciuria, PTH levels and odds of secondary hyperparathyroidism compared to no treatment. These associations were attenuated in patients who were coadministered thiazides. Diuretic choice is a potentially modifiable determinant of secondary hyperparathyroidism in CKD.

    Full Text Available Objective: Gastrointestinal complications are responsible for substantial morbidity and mortality among renal allograft recipients. We retrospectively analyzed incidence of these complications and their impact on the patient outcome. Materials & Methods: Between 1998 to Aug 2002, 558 live related renal transplants were performed at our center. The immunosuppression used consisted mainly of cyclosporine, azathioprine and prednisolone, though varied in some patients. These patients were followed for any occurrence of significant gastrointestinal problems. Results: Out of the of 538 renal transplant recipients studied, gastro esophageal ulcerations were seen in 3% patients. Acute pancreatitis was observed in twelve (2.2% patients and four patients had acute intestinal obstruction secondary to fecal impaction. Infectious complications included acute diarrheas in 18% of patients. Three patients developed abdominal tuberculosis. Acute rejection episodes were encountered in 26% of the patients. During these episodes, 58% of patients experienced prolonged ileus. Most of these complications (66% occurred within first one-year post transplant. Three patients presenting with acute intestinal obstruction required laparotomy (two- bands, one-intussusception. There were four mortalities -two patients had severe pancreatitis, one patient had massive upper GI bleed and one succumbed due to perforation peritonitis. Conclusions: Gastrointestinal complications account for significant morbidity and mortality in renal transplant recipients. Paralytic ileus secondary to acute vascular rejection is quite common and resolves spontaneously with recovery of renal function.

    The risk of fractures after kidney transplantation is high. Hyperparathyroidism frequently persists after successful kidney transplantation and contributes to bone loss, but its impact on fracture has not been demonstrated. This longitudinal study was designed to evaluate hyperparathyroidism and its associations with mineral disorders and fractures in the 5 posttransplant years. We retrospectively analyzed 143 consecutive patients who underwent kidney transplantation between August 2004 and April 2006. The biochemical parameters were determined at transplantation and at 3, 12 and 60 months posttransplantation, and fractures were recorded. The median intact parathyroid hormone (PTH) level was 334 ng/L (interquartile 151-642) at the time of transplantation and 123 ng/L (interquartile 75-224) at 3 months. Thirty fractures occurred in 22 patients. The receiver operating characteristic (ROC) curve analysis for PTH at 3 months (area under the ROC curve = 0.711, p = 0.002) showed that a good threshold for predicting fractures was 130 ng/L (sensitivity = 81%, specificity = 57%). In a multivariable analysis, independent risk factors for fracture were PTH >130 ng/L at 3 months (adjusted hazard ratio [AHR] = 7.5, 95% CI 2.18-25.50), and pretransplant osteopenia (AHR = 2.7, 95% CI 1.07-7.26). In summary, this study demonstrates for the first time that persistent hyperparathyroidism is an independent risk factor for fractures after kidney transplantation. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

    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.

    Calcitriol is a standard therapy for secondary hyperparathyroidism in chronic renal failure. We evaluated whether the effect of daily or intermittent calcitriol administration is more efficient in enhancing bone growth in renal failure with advanced secondary hyperparathyroidism in weanling 5/6 nephrectomized rats loaded with phosphorus to induce severe secondary hyperparathyroidism. The animals were treated daily or three times weekly with calcitriol for 4 weeks but the total weekly dose of calcitriol was the same. Although calcitriol increased the serum calcium, it did not lower parathyroid hormone (PTH) or improve tibia and body length. Animals with renal failure and advanced secondary hyperparathyroidism had decreased PTH/PTHrP, which was accompanied by an increase in the cyclin kinase inhibitor p57(Kip2). Calcitriol treatment upregulated the PTH/PTHrP receptor but also increased inhibitors of cell proliferation such as p21(Waf1/Cip1), IGFBP3, and FGFR3. Calcitriol also enhanced markers of chondrocyte differentiation, such as IGF1, Vitamin D receptor, FGF23, and bone morphogenetic protein-7. Receptor activator of nuclear factor-kappabeta ligand levels improved with calcitriol treatment but without changes in osteoprotegerin suggesting an enhancement of osteo/chondroclastogenesis and mineralization. Overall, both daily and intermittent calcitriol had similar effects on endochondral bone growth in phosphorus-loaded rats with renal failure.

    Chronic kidney disease is a frequent complication following heart and combined heart-lung transplantation. The aim of this study was to analyse the outcome of a subsequent renal transplant in heart, lung and heart-lung transplantation recipients. All heart, lung and heart-lung transplant recipients who received a subsequent renal transplant over a 27-year period in a national heart and lung transplant centre were included in this study. A total of 18 patients who had previously undergone heart (n = 6), lung (n = 7) and heart-lung (n = 5) transplantation received a renal transplant. The mean duration to development of end-stage kidney disease (ESKD) was 115 ± 45.9 months. The most common contributor to ESKD was calcineurin inhibitor nephrotoxicity. The 5-year patient survival and graft survival rates were 91.7 and 85.6%, respectively. The median creatinine level at the most recent follow-up was 123 μmol/L, IQR 90.8-147.5. The overall outcome of renal transplantation following previous non-renal solid organ transplantation is excellent considering the medical complexity and co-morbidities of this patient population. Renal transplantation represents an important treatment option for ESKD in non-renal solid organ transplant recipients.

    Solid organ transplant recipients have an increased incidence of skin infections resulting from immunosuppression. Common pathogens include herpes simplex virus, varicella zoster virus, Gram-positive bacteria and dermatophytes; however, the contribution of multicellular parasitic organisms to dermatologic disease in this population remains less studied. Demodex folliculorum and brevis are commensal mites that reside on human skin. Proliferation of Demodex mites, or demodicosis, is associated with rosacea and rosacea-like disorders, particularly in immunocompromised populations, although their ability to cause disease is still the subject of debate. We present a case series of four renal transplant recipients with the singular chief complaint of acne rosacea who we diagnosed with demodicosis. Although one of the four patients showed complete resolution following initial antiparasitic therapy, the other three required subsequent antibacterial treatment to fully resolve their lesions. We suggest that demodicosis may be more prevalent than once thought in solid organ transplant recipients and showed that Demodex-associated acne rosacea can be effectively treated in this population. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    To review epidemiologic data's and medical results of deceased donation in renal transplantation. Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association, "brain death; cardiac arrest; deceased donation; organ procurement; transplantation". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 2498 articles, 8 official reports and 17 newspaper articles were identified; after careful selection 157 publications were eligible for our review. Deceased donation may involve either brain death or non-heartbeating donors (NHBD). Organ shortage led to the procurement of organs from expanded-criteria donors, with an increased age at donation and extended vascular disease, leading to inferior results after transplantation and underlining the need for careful donor management during brain death or cardiac arrest. Evolution of French legislation covering bioethics allowed procurement from Maastricht categories II and recently III non-heartbeating donors. The increase of organ shortage emphasizes the need for a rigorous surgical technique during procurement to avoid loss of transplants. A history or current neoplasm in deceased-donors, requires attention to increase the pool of organs without putting the recipients at risk for cancer transmission. French NHBD program, especially from Maastricht category III, may stand for a potential source of valuable organs. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    In renal transplant recipients, the risk of developing bladder cancer and rate of diagnosis of advanced staged bladder cancer are generally higher than the general population. Also, it is more challenging to treat renal transplant recipients than the regular patient population. We aimed to evaluate the efficacy and safety of radical cystectomy (RC) and urinary diversion with ileal conduit in renal transplant recipients. We identified 2 patients with prior history of renal transplantation who underwent RC and ileal conduit urinary diversion for bladder cancer. Preoperative clinical and demographic data were presented and outcomes were assessed. The RC and ileal conduit urinary diversion were performed in the first patient 56 months after renal transplantation and in the second patient 64 months after renal transplantation. Clinical staging was high-grade T2 transitional cell cancer of the bladder for patient 1 and T2 with pure squamous cell cancer of the bladder for patient 2. No perioperative or postoperative complication and no graft dysfunction occurred in either patient. Our experience demonstrated that RC with ileal conduit reconstruction in renal transplant recipients is safe and feasible. Copyright © 2016 Elsevier Inc. All rights reserved.

    During the years 1979-1993 22 individuals were intoxicated in Sweden by the mushroom Cortinarius speciosissimus. Nine of them developed end-stage renal failure (ESRF), and we describe five who have received renal transplants. Three were transplanted after 6-9 months on haemodialysis; the other two regained some renal function after 2-6 months on haemodialysis, but had to be restarted on dialysis 24-30 months later and were eventually transplanted. Two patients had kidneys donated by a father and a brother respectively, three had cadaveric organs. All five developed satisfactory renal function with current glomerular filtration rate (GFR) 31-79 ml/min (mean 56.2) after 5-10 (mean 7.0) years. To our knowledge, renal transplantation after Cortinarius poisoning has not been reported before.

    The first child born to a renal transplant patient who was the first woman undergone a renal transplant from her identical twin celebrated his 53th birthday on March 10, 2009. Since this first experience, over 14,000 births among women with transplanted organs have been reported worldwide and several more also not reported. Pregnancy is now considered a frequent part of women after organ transplantation. However, substantial gaps remain in our knowledge about pregnancy in the transplant recipient and its effects on the mother and child. As well, several ethical concerns have been raised about the wisdom of pregnancy for a woman with a proportionally lower life span with expected medical complications. In this review article we tried to address all issues related to pregnancy after renal transplantation.

    Impairment of growth in children with chronic renal failure may be due, in part to the insensitivity to the actions of growth hormone by insulin-like growth factor-I (IGF-I) because of accumulations of IGF binding proteins. There are a few studies describing the changes that occur in the growth plate in renal failure. None of these studies has simultaneously compared the modifications in the expression of selected markers of endochondral bone formation in renal failure with mild or advanced secondary hyperparathyroidism. Forty-six rats that underwent 5/6 nephrectomy (Nx) were fed either standard rodent diet (Nx-control) or high phosphorus diet to induce advanced secondary hyperparathyroidism (Nx-phosphorus) for 4 weeks. Sections of the tibia were obtained for growth plate histomorphometry, immunohistochemistry studies, and in situ hybridization experiments for selected markers of endochondral bone formation. Weight gain, gain in length, and tibial length were less in Nx animals. Serum parathyroid hormone (PTH) and phosphorus levels were higher and serum calcium levels were lower in the Nx-phosphorus group. The width of the growth plate was much shorter in the Nx-phosphorus group due to a decrease in both proliferative and hypertrophic zones. IGF-I protein and IGF binding protein-3 staining were diminished in both Nx groups without changes in the IGF-I receptor expression; the decline in IGF-I protein expression was much lower in the Nx-phosphorus group. PTH/PTH receptor protein (PTHrP) receptor mRNA transcripts decline and tartrate-resistant acid phosphastase (TRAP) staining increased only in the Nx-phosphorus group. The growth impairment in renal failure may be worsened by the severity of secondary hyperparathyroidism.

    Full Text Available To evaluate our experience with pediatric renal transplantation at King Hussein Medical Center, the medical records of 71 pediatric patients who underwent a renal transplantation procedure between the years 2004 and 2010 or started follow-up at our center within one week of transplantation done elsewhere were reviewed. Over the seven-year period, 71 children under the age of 14 years who received their first renal transplant were studied. About 56% (40 were males. The mean age was 9.44 ± 2.86 years. Dysplastic kidney was the most common cause of end-stage renal failure in our group, followed by glomerulonephritis. Mothers were the donors in 39.4% of the cases, followed by fathers. Twenty-three patients (32.4% were transplanted preemptively. The overall one-year graft survival was 96%, three-year survival was 95%, and the five-year survival was 88%. Prednisone, tacrolimus, and mycophenolate mofetil formed the main-stay of immunosuppressive agents. We have developed a successful live donor program for renal transplantation in children at King Hussein Medical Center in Amman. Although our experience is still short, the graft survival is similar to that achieved in the developed world, especially with preemptive transplant.

    Like cyclosporine (CsA), tacrolimus acts through the inhibition of renal phosphatase calcineurin. CsA induces reversible vasoconstriction, causing a transient reduction of renal plasma flow in patients with renal transplantation. The aim of this study was to determine the effect of tacrolimus on renal plasma flow in renal transplanted children. Eight children were studied with a median age of 10.6 years, a mean glomerular filtration rate (inulin clearance) of 55 ml/min per 1.73 m2 (range 29-95), and a mean follow-up after transplantation of 5.6 months. Effective renal plasma flow (ERPF) was studied in each patient for 12 h after tacrolimus administration. Clearances were obtained every 2 h for 12 h after drug administration. Tacrolimus pharmacokinetics was also studied. Average ERPF at the start of the test was 289 ml/min per 1.73 m2 (range 177-404, SD +/- 106). Variation in each of the 2-h periods was not significant, although a mild reduction of plasma flow was observed in three of the eight children. No correlation was found between tacrolimus AUC, peak, or trough levels and renal blood flow variations. Despite the relatively small number of patients studied, these data suggest that, in vivo, a therapeutic oral dose of tacrolimus is not necessarily followed by a significant reduction of ERPF in renal transplanted children.

    Hyperparathyroidism is a common complication in chronic kidney disease and might persist in up to 25% of patients after transplantation. In this setting, vitamin D analogues further aggravate persistent hypercalcemia and cinacalcet has not been approved for these patients, some of whom will require parathyroidectomy to correct post-transplantation hyperparathyroidism. In this single-center, retrospective study we aimed to analyze the long-term effect of parathyroidectomy on calcium, phosphorus, and parathyroid hormone (PTH) levels and its effect on allograft function in kidney transplantation patients submitted to parathyroidectomy. Fifteen patients underwent parathyroidectomy between January 2005 and January 2015; median age 54 years old; 8 (53.3%) were receiving cinacalcet at the time of surgery. Pre-parathyroidectomy median values of intact PTH, calcium, and phosphorus were, respectively, 262 pg/mL, 10.8 mg/dL, and 2.4 mg/dL. Surgery consisted of uniglandular parathyroidectomy in 5 (33.3%) patients, biglandular in 4 (26.7%), and subtotal in 6 (40%). There was no surgery-related mortality. Compared with baseline, there was a decrease of PTH (262 pg/mL vs. 106 pg/mL, P = .001), calcium, and phosphorus levels (10.8 mg/dL vs. 10.4 mg/dL, P = .3; 2.4 vs. 2.9 mg/dL, P = .05) 1 year after surgery; with normalization of serum calcium at the end of follow-up (10.8 mg/dL vs. 9.4 mg/dL, P = .04). A decrease in estimated glomerular filtration rate occurred 1 month post-surgery (62.7 mL/m vs. 49.7 mL/m, P = .006) but returned to baseline 1 year after surgery (62.7 mL/m vs. 60.8 mL/m, P = .73). Parathyroidectomy appears to be a safe procedure and should be considered in kidney transplantation patients with persistent post-transplantation hyperparathyroidism. Although there was an acute estimated glomerular filtration rate decrease, we observed no long-term deterioration in allograft function. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Acute renal artery thrombosis after kidney transplantation

    Full Text Available Early kidney transplant loss as a result of acute thrombosis of the renal artery remains a constant and devastating complication, with an incidence of 0.2-7.5%. While uncommon, arterial obstruction in the early postoperative period is a surgical emergency and must be ruled out if previously established diuresis ceases suddenly. Arterial thrombosis may occur as a result of injury to a diseased artery, problems with anastomoses, hypercoagulability or malpositioning of the allograft. In this study, we analyzed data on a group of 105 renal transplant recipients who presented with acute postoperative graft dysfunction between January 2006 and May 2012, to identify cases of acute renal artery thrombosis. We report on our experience of immediate re-transplantation following early kidney transplant thrombosis. Overall, two (1.9% patients suffered early (within 48 hours of surgery allograft renal artery thrombosis. In both patients, transplantation had not been complicated by atherosclerotic lesions or other thrombophilic states and postoperative diuresis had been successfully achieved, but diuresis ceased abruptly during the early postoperative period. Emergent duplex ultrasound scans were performed and acute renal artery thrombosis was detected in both patients. The patients were operated immediately and retransplantation procedures were conducted. We have reported our experience of immediate retransplantation following early primary graft dysfunction due to renal artery thrombosis. In conclusion, close monitoring of postoperative diuresis and, if necessary, immediate retransplantation in this situation can prove to be a successful treatment for preventing graft loss.

    Full Text Available Cystinosis is an autosomal recessive, lysosomal storage disease characterised by the accumulation of the amino acid cystine in different organs and tissues. It is a multisystemic disease that can present with renal and extra-renal manifestations. In this report, we present the first case of transplanted nephropathic cystinosis in a Tunisian child. A 4-year-old Tunisian boy born to nonconsanguineous parents, was treated in our medical services in 1990 for cystinosis. Since the age of five months, he developed symptoms of severe weight loss, vomiting, dehydration, and polyuria. He manifested the Toni Debré Fanconi syndrome. Slit lamp examination of the anterior segment of both eyes revealed fine, shiny crystal-like deposits diffusely distributed in the corneal epithelium and the stroma. Our patient had renal failure. At the age of seven, he reached terminal chronic renal failure and was treated with peritoneal dialysis. Hemodialysis was started at the age of nine years. At the age of 13 years, he received a renal transplantation and was started on cysteamine 1999, five months after the renal transplantation. Currently, the patient is 28-year-old. The graft has survived 15 years after the transplantation. Renal functions were stable with a serum creatinine of 123 μmol/L at last follow-up.

    The regional group of renal transplantation in Toulouse includes a medico-surgical team which participates to all the activities of this group. Dialysis and transplantation are covered in a center organized for the care of children. This branch is part of the Regional Hospital. From 15 years old on patients are moved from the pediatric branch to the medico-surgical center taking care of adults. Both teams within the regional hospital share the responsability of taking off kidneys from cadaveric donors and collaborate to France-Transplant and Euro-Transplant. Since the pediatric center in charge of renal failure has opened, 32 children underwent chronic hemodialysis. Some of these patients are presently treated in the center for adults. Fourteen children were grafted and seven are at this moment waiting to receive transplantation. The average number of transplantations per year is from 1 to 4. These fourteen children underwent renal transplantation with kidneys from cadaveric donors. Only one has been provided by Toulouse. Diuresis resumed immediately in 8 cases, later in 5. An extremely acute reject was observed in one case and transplantectomy had to be performed 10 days after transplantation. Eight children presented acute reversible reject which, for 4 of them, evoluated towards chronicle reject. Eight children presented a chronicle reject: 4 of them are again in dialysis. Altogether 8 kidneys are functioning (seven years in the longest case). Five children resumed chronic dialysis. One patient died of acute pancreatitis. He underwent a portocaval shunt for type I glycogenosis which ended in a hyperuricemic nephropathy evoluating towards renal failure forcing a transplantation. The rehabilitation of transplanted children was always satisfactory.

    1998-10-01

    In rats with genetically hypoplastic kidneys (hpk/hpk) and associated hypogonadism (hgn/hgn), their kidneys contain only one-quarter the number of nephrons that are found in those of normal rats [26]. Not surprisingly, therefore, renal excretive function has been shown to be depressed in hpk/hpk rats [26]. In the study presented here, we have examined the process of the progression of renal failure and the development of renal secondary disease in hpk/hpk rats. The plasma concentrations of urea-nitrogen and creatinine were significantly higher in adult hpk/hpk rats than in normal rats. These values elevated gradually and the degree of renal histological damage also progressed with advancing age in the hpk/hpk rats. In addition, renal anemia appeared at 140 days of age or later in these rats, and hyperplasia of the parathyroid glands was visible macroscopically at 280 days of age. In the hpk/hpk rats plasma levels of calcium and phosphorus were significantly lower and higher than in normal rats, respectively, at 280 days of age. Pathologically, the left femora of hpk/hpk rats exhibited fibrous osteodystrophy at 280 days of age and the calcium content of the right femora (as a percentage of the dry weight of bone) was significantly lower than in normal rats at both 210 and 280 days of age. These results indicate that the reduced nephrogenesis of the hpk/hpk rats causes progressive renal failure, secondarily inducing anemia, hyperparathyroidism, and osteodystrophy.

    Apolipoprotein AII (ApoAII) amyloidosis, first reported in 2001 in a family with renal amyloidosis, is associated with mutations in the stop codon of the apolipoprotein AII gene resulting in a carboxyl terminal peptide extension of 21 amino acid residues in the protein. Since death from this form of amyloidosis is due to renal failure, kidney dialysis and renal transplantation are presently the only two therapeutic options. We report the case of a Caucasian man who developed proteinuria in his late 20's, had renal biopsy at the age of 33 which gave the diagnosis of renal amyloidosis, and required continuous ambulatory peritoneal dialysis by age 45. He received a cadaver renal transplant at age 47 and has maintained stable renal function for nine years without other evidence for organ system dysfunction from amyloidosis. Laboratory studies confirmed persistence of the ApoAII variant in the patient's plasma in addition to the normal ApoAII protein. This is in agreement with the DNA analysis which showed the patient to be heterozygous for the ApoAII stop78Gly mutation. These results indicate that renal transplantation is an effective therapy for apolipoprotein AII amyloidosis since recurrence of amyloid in the graft and progression of other organ involvement may be very slow.

    2013-01-01

    Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vitamin D deficiency. Recognition of this phenotype of primary hyperparathyroidism, normocalcemic primary hyperparathyroidism, supports a biphasic chronological time course in some individuals in which PTH levels are first elevated but serum calcium is normal, followed by the development of frank hypercalcemia. This review focuses on the available literature regarding this newly described phenotype of primary hyperparathyroidism. PMID:23374739

    Scintigraphy is useful for monitoring perfusion and function of renal transplant, as well as for diagnosing miscellaneous surgical. This non-invasive imaging technique, which uses no deleterious products, is an attractive alternative for patients. This is especially true for those patients in early post-transplant course, with immunity depression and often impairment of renal function. Otherwise, multiple indices with a large range of inter-patient values has not favoured a methodological and interpretative consensus. Furthermore, the poor specificity of renogram patterns does not allow for discrimination of all etiologies with only one scintigraphy. Nevertheless, follow-up with iterative scintigraphy may be helpful due to the high intra-patient reproducibility and to the early appreciate change of parameters, according to clinical and histological renal post-transplant outcome.

    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.

    Background Renal replacement therapy was first introduced in Yemen in 1978 in the form of hemodialysis. Twenty years later, the first renal transplantation was performed. Kidney transplantations were started in socially and financially challenging circumstances in Yemen in 1998. A structured program was established and has been functioning regularly since 2005. A pediatric transplantation program was started in 2011. Material and Methods This was a prospective study of 181 transplants performed at the Urology and Nephrology Center between May 1998 and 2012. All transplants were from living related donors. The immunosuppressive protocol consisted initially of double therapy with steroid and mycophenolate mofetil (MMF). Subsequently, triple therapy with addition of a calcineurin inhibitor was introduced. Primary graft function was achieved in 176 (97.2%) recipients. Results Cold ischemia time was 48-68 min. Episodes of acute rejection in 12 patients were treated with high-dose steroids. Anti-thymocyte globulin (ATG) was used in cases of vascular or steroid-resistant rejection in 2 patients. The post-transplant complications, either surgical or medical, were comparable to those recorded in the literature. Conclusions Renal transplantation is a good achievement in our country. The patients and graft survival rates are comparable to other reports.

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

    Terminal renal insufficiency is characterized by the need for renal replacement therapy for survival of the patient. In addition to several types of dialysis treatment, successful renal transplantation offers the best form of renal replacement therapy in terms of long-term patient survival and quality of life. Living donor renal transplantation offers the best conditions concerning quality of organ transplanted and graft survival. The risk of complications associated with renal transplantation are manageable; however, these must be weighed against the potential benefits of successful transplantation.

    Within this prospective, open-label, self-controlled study, we evaluated the long-term effects of the calcimimetic cinacalcet on calcium and phosphate homeostasis in 44 kidney transplant recipients (KTRs) with hypercalcemic hyperparathyroidism by comparing biochemical parameters of mineral metabolism between pre- and posttreatment periods. Results are described as mean differences (95% CIs) between pre- and posttreatment medians that summarize all repeated measurements of a parameter of interest between the date of initial hypercalcemia and cinacalcet initiation (median of 1.6 (IQR: 0.6–3.8) years) and up to four years after treatment start, respectively. Cinacalcet was initiated after 1.8 (0.8–4.7) years posttransplant and maintained for 6.2 (3.9–7.6) years. It significantly decreased total serum calcium (−0.30 (−0.34 to −0.26) mmol/L, P hyperparathyroidism in KTRs in the long-term and increased low Pi levels without causing hyperphosphatemia, pointing towards a novel indication for the use of cinacalcet in KTRs.

    Full Text Available INTRODUCTION: Several methods have been proposed to improve operative success in renal hyperparathyroidism. OBJECTIVE: To evaluate stereomicroscopy in parathyroid tissue selection for total parathyroidectomy with autotransplantation in secondary (SHPT/tertiary (THPT hyperparathyroidism. METHODS: 118 renal patients underwent surgery from April of 2000 to October 2009. They were divided into two groups: G1, 66 patients operated from April of 2000 to May of 2005, with tissue selection based on macroscopic observation; G2, 52 patients operated from March of 2008 to October 2009 with stereomicroscopy for tissue selection searching for the presence of adipose cells. All surgeries were performed by the same surgeon. Patients presented SHPT (dialysis treatment or THPT (renal-grafted. Follow-up was 12-36 months. Intra-operative parathyroid hormone (PTH was measured in 100/118 (84.7% patients. RESULTS: Data are presented as means. G1 included 66 patients (38 SHPT, 24 females/14 males; 40.0 years of age; 28 THPT, 14 females/14 males; 44 years of age. G2 included 52 patients (29 SHPT, 11 females/18 males; 50.7 years of age; 23 THPT, 13 females/10 males, 44.4 years of age. SHPT patients from G2 presented preoperative serum calcium higher than those of SHPT patients in G1 (p < 0.05, suggesting a more severe disease. Definitive hypoparathyroidism was found in seven of 118 patients (5.9%. Graft-dependent recurrence occurred in four patients, two in each group. All occurred in dialysis patients. CONCLUSION: Stereomicroscopy in SHPT/THPT surgical treatment may be a useful tool to standardize parathyroid tissue selection.

    Full Text Available O transplante renal é a melhor modalidade de terapia renal substutiva até o momento. Infelizmente, a sobrevida do enxerto é interrompida pelos episódios de rejeição aguda ou mesmo de fibrose intersticial/atrofia tubular. A dosagem de quimiocinas e citocinas urinárias como ferramenta alternativa para o diagnóstico dessas complicações tem sido relatada nos últimos anos. Estas substâncias estão sabidamente relacionadas com os mecanismos imunoinflamatórios do transplante renal, podendo ser detectadas no tecido renal, no plasma e na urina de pacientes transplantados. Drogas anti-inflamatórias, inibidores do sistema renina angiotensina e alguns antagonistas de receptores de citocinas, ainda utilizados em nível experimental, podem interferir com a expressão desses mediadores do sistema imune e, por conseguinte, alterar a evolução do transplante renal. Neste sentido, pretende-se neste artigo fazer uma revisão dos estudos sobre a mensuração de citocinas/quimiocinas e dos seus receptores na urina, no plasma e no tecido renal de pacientes transplantados, no intuito de avaliar uma possível associação entre os níveis desses mediadores e as complicações do transplante renal e sobrevida do enxerto.Renal transplantation is currently the best modality of renal substitutive therapy. Unfortunately graft survival is interrupted by episodes of acute rejection or even interstitial fibrosis/tubular atrophy. The measurement of urinary chemokines and cytokines as an alternative tool to diagnose these complications has been reported in past years. Those substances are clearly related to the immunoinflammatory mechanisms of renal transplantation, and can be detected in renal tissue, plasma, and urine samples of transplant recipients. Anti-inflammatory drugs, renin-angiotensin system inhibitors, and some antagonists of cytokines' receptors, although used only experimentally, can interfere with the expression of these immune system mediators and

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    Full Text Available Brown tumors are unusual but serious complications of renal osteodystrophy. We retrospectively studied 12 patients presenting with chronic renal failure and brown tumor related to secondary hyperparathyroidism. Eleven patients were on chronic hemodialysis. The median duration between renal failure and end stage renal failure was 36 months (range: 12-190 months and the median duration in dialysis for 11 cases: 92 months (range: 72-252 months. The bone pain was noted in all cases (100%, pathological fracture in one case (8% and a palpable bone tumor in 10 cases (83%. Elevated serum Calcium (> 2.35 mmol/L was noted in four cases (33%, elevated serum Phosphate (> 1.78 mmol/L in ten cases (80%, elevated serum Alkaline Phosphate (> 290 UI/L in all cases and intact PTH was > 300 pg/mL in all cases with a serum median rate at 1475 pg/mL (range: 682-3687 pg/L. Subtotal parathyroidectomy was performed in all cases with a resultant decrease in size of brown tumors. We report here patient with CKD with unusual frequency and variable locations. This may be attributed tothe lack of the new calcium free phosphate binders and calcimimetics.

    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.

    Hyperhomocystinemia is an established risk factor for cardiovascular events and has been identified as an important cause of morbidity and mortality in renal transplant recipients. This investigation was aimed to determine the effect of age and transplant duration on serum total homocysteine (tHcy) levels in renal transplant recipients. We analyzed serum levels of tHcy, albumin, alkaline phosphatase, alanine transferase, bilirubin, calcium, corrected calcium, cholesterol, creatinine, folate, phosphate, potassium, sodium, triglycerides, urea and vitamin B12 in 88 transplant patients (ages, 14-67 years; transplant duration, 1-252 months) and 60 control subjects. Our results showed significant hyperhomocystinemia in transplant patients (19.92 +/- 0.72) as compared to controls (9.28 +/- 0.25), while male subjects in both groups had significantly higher tHcy than females. There was no correlation between patients' age and serum tHcy, whereas the time after transplantation was significantly correlated with tHcy (r=0.318, P<0.01). A significant correlation was observed between tHcy and serum urea, creatinine, vitamin B12 and potassium in renal transplant patients. This study clearly demonstrated significant hyperhomocystinemia and renal impairment in transplant recipients. A time-course increase in serum tHcy during posttransplant duration warrants long-term monitoring of patients for effective clinical management.

    Metastatic pulmonary calcification (MPC) is common in patients with chronic renal failure. The authors experienced a patient with chronic renal failure and primary hyperparathyroidism by parathyroid adenoma accompanied with rapid progressions of MPC and alveolar hemorrhage. Recent chest radiographs, compared with previous chest radiographs, showed rapid accumulation of calcification in both upper lungs. Following up on the high-resolution CT scan after five years demonstrates more increased nodules in size and ground glass opacity. The patient was diagnosed with MPC and alveolar hemorrhage by transbronchial lung biopsy. We assumed rapid progression of MPC and alveolar hemorrhage in underlying chronic renal failures could be a primary hyperparathyroidism which may be caused by parathyroid adenoma detected incidentally. Therefore parathyroid adenoma was treated with ethanol injections. Herein, we have reported on CT findings of MPC with alveolar hemorrhage and reviewed our case along with other articles.

  8. Simultaneous Bilateral Rupture of the Triceps Tendon in a Renal Transplant Patient

    Full Text Available The unilateral rupture of the triceps brachii tendon is a rare lesion representing 1% of all tendon injuries. The most common causes are the result of a contraction against resistance (especially weightlifters and direct trauma. It has also been associated with systemic diseases such as diabetes mellitus, chronic renal failure, secondary hyperparathyroidism, and use of systemic corticosteroids. Simultaneous bilateral rupture of the triceps tendons is less frequent and has been described in association with chronic metabolic disorders, especially in those patients on hemodialysis. This paper presents a case of bilateral triceps tendon rupture of a 36-year-old woman with renal transplantation secondary to chronic renal failure. Early surgical repair was performed using a bone tunnel technique with a nonabsorbable suture. Clinically active extension with 135 degrees of range of motion was achieved.

  9. Secondary and tertiary hyperparathyroidism.

    Science.gov (United States)

    Jamal, Sophie A; Miller, Paul D

    2013-01-01

    We reviewed the etiology and management of secondary and tertiary hyperparathyroidism. Secondary hyperparathyroidism is characterized by an increase in parathyroid hormone (PTH) that is appropriate and in response to a stimulus, most commonly low serum calcium. In secondary hyperparathyroidism, the serum calcium is normal and the PTH level is elevated. Tertiary hyperparathyroidism is characterized by excessive secretion of PTH after longstanding secondary hyperparathyroidism, in which hypercalcemia has ensued. Tertiary hyperparathyroidism typically occurs in men and women with chronic kidney disease usually after kidney transplant. The etiology and treatment of secondary hyperparathyroidism is relatively straightforward whereas data on the management of tertiary hyperparathyroidism is limited to a few small trials with short follow-up.

    Full Text Available The sensitivity of parathyroid glands to a low calcium level in plasma results in parathyroid hormone (PTH release in order to restore the normal Ca2 concentration. Hyperparathyroidism is a common endocrinopathy, caused by uncontrolled growth of parathyroid cells. In primary hyperparathyroidism, hypercalcemia develops due to extensive autonomous secretion of PTH. Secondary hyperparathyroidism is a well-established complication of chronic renal insufficiency, where marked parathyroid hyperplasia occurs, especially in patients with long dialysis vintage. The elevated PTH level in the circulation is a direct result of renal function disturbances, vitamin D deficiency, and impaired calcium/phosphate metabolism. After successful kidney transplantation, the normalization of kidney function fails to normalize the secretion of PTH by parathyroid glands, which have become relatively autonomous and unresponsive to hypercalcemic conditions in the plasma. The development of tertiary hyperparathyroidism occurs in these conditions.The aim of our report is to present current views on the clinical, pathological and biochemical features of primary, secondary and tertiary hyperparathyroidism. The diagnostics of calcium/phosphate abnormalities in parathyroid gland disorders, as well as some aspects of hyperparathyroidism treatment, are briefly summarized.

    The aim of this study was to investigate the impacts of parathyroidectomy (PTX) towards the renal anemia and nutritional status of hemodialysis patients with secondary hyperparathyroidism (SHPT). 32 patients, enrolled into the blood purification center of our hospital for the hemodialysis treatment, were collected and divided into the PTX group and the non-PTX group, with 16 patients in each group. The changes of relevant indicators such as immunoreactive parathyroid hormone (iPTH), anemia and nutrition were observed before, 1-, 3-, 6-month after the treatment. The contents of iPTH, Ca, P and Ca × P of the PTX group decreased rapidly 1 month after the surgery; while Hb and Hct increased significantly from the 1st postoperative month; the dosage of EPO was significantly reduced 3-month after the surgery; the content of Alb gradually increased from the 3(rd) postoperative month; the content of TG decreased significantly from the 6(th) postoperative month; while the contents of BMI and TSF increased significantly from the 6(th) postoperative month, which exhibited the statistically significant differences when compared with the preoperative and the non-PTX group (P renal anemia and nutritional status; SHPT was the important factor that would affect the renal anemia and malnutrition; PTX could reduce the amount of EPO, and reduce the economic burden of patients.

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

    Many studies have demonstrated a strong association between elevated plasma total homocysteine (tHcys) levels and vascular disease. The aim of the present study was to determine the plasma levels of tHcys in pediatric recipients of renal transplants, to establish possible correlations with renal function, lipid profile, and folate and vitamin B12 status, and to assess whether the C677T and A1298C polymorphisms in the 5, l0-methylenetetrahydrofolate reductase (MTHFR) gene were associated with a particular risk. A total of 26 transplanted children and adolescents were investigated. tHcys levels were elevated in transplanted patients (12.9+/-4.8 micro mol/l) and 73% of these displayed values above the 97th percentile of healthy children. Plasma tHcys correlated negatively with creatinine clearance ( r=-0.58, PMTHFR 677TT/1298AA genotype. In a multiple stepwise regression model plasma creatinine and triglyceride levels and MTHFR 677TT/1298 AA genotype accounted for 60% of the observed plasma tHcys variability. The MTHFR 677CT/1298 AC genotype was not a significant predictor of tHcys plasma levels. We conclude that a moderate degree of hyperhomocysteinemia is often present in renal transplant children and that folate supplementation must be considered in this population.

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

    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

    Obesity has been a relative contraindication for renal transplantation. This study evaluates the impact of pretransplant body mass index (BMI) on renal transplant outcomes in a single institution in the era of modern immunosuppression. A 10-y retrospective analysis was undertaken of 454 consecutive patients who received a renal transplant at Westmead Hospital from January 1, 2001 to December 31, 2010. The role of pretransplant BMI on patient survival, graft survival, surgical complications, and postoperative complications was studied. The mean age of transplant of this study population was 45.4 ± 13.0 y. Live donation rate was 53.5%, and 60.6% were male. The median preoperative BMI was 25.6 (range, 14.3-51.4). One-year and 5-y patient survival were 97.4% and 86.6%, respectively, whereas 1-y and 5-y death-censored graft survival were 97.1% and 91.9%, respectively. Patients with BMI >30 did not exhibit any significant difference in survival or graft failure but had higher surgical wound infection rates (hazard ratio 3.95, P < 0.01). Patients with preoperative BMI <18.5 were associated with a six-fold increase in both death and death-censored graft failure (P < 0.01). Pretransplant obesity increases wound infection but is not a contraindication to renal transplantation. Future prospective studies are required to further define the impact of low preoperative BMI <18.5. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients′ records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4. The estimated prevalence of hypertension in this study was almost 85%. We found no significant difference in the prevalence of hypertension in terms of gender, year of transplantation, duration of transplantation, type of donor, number of previous transplants, diagnosis of renal artery stenosis, etiology of kidney disease, diagnosis of diabetes after transplantation, diagnosis of cerebrovascular accidents, or mean dose of prednisolone and cyclosporine. There was a statistically significant association between increased level of blood pressure and old age (above 50 years, original disease associated with hypertension, history of hypertension on dialysis, acute rejection (once or more, presence of protienuria (more than 0.3 mg/day, abnormality of ECG, or serum creatinine above 300 µmol/L. We conclude that hypertension is highly prevalent in the renal transplant population in Saudi Arabia. Risk

    Full Text Available Post-transplant erythrocytosis (PTE is characterized by persistently ele-vated hematocrit level 0 51%. This complication is reported to develop in 10-20% of renal allografts recipients, mostly 2 years after kidney transplantation. PTE is self-limited in 25% of the patients; however it may persist in patients with an increased susceptibility for thrombosis and potential fatal outcome. To evaluate the prevalence and risk factors of PTE in our center, we reviewed the records of 235 patients who received renal allografts from 1999 to 2004. Polycythemia was found in 45 (19% patients. There was no significant correlation of polycythemia and age, history of hypertension, diabetes, pre-transplant hematocrit level, pre-transplant history of transfusion, graft′s function, and source of kidney. A significantly higher proportion of PTE patients were males, patients with history of polycystic kidney disease, and patients with glomerulonephritis. We conclude that PTE is an important complication of kidney transplantation. There are several risk factors that should be addressed to prevent this complication.

    Full Text Available Kidney transplantation offers best hope to women with end-stage renal disease who wish to become pregnant. Pregnancy in a kidney transplant recipient continues to remain challenging due to side effects of immunosuppressive medication, risk of deterioration of allograft function, risk of adverse maternal complications of preeclampsia and hypertension, and risk of adverse fetal outcomes of premature birth, low birth weight, and small for gestational age infants. The factors associated with poor pregnancy outcomes include presence of hypertension, serum creatinine greater than 1.4 mg/dL, and proteinuria. The recommended maintenance immunosuppression in pregnant women is calcineurin inhibitors (tacrolimus/cyclosporine, azathioprine, and low dose prednisone; and it is considered safe. Sirolimus and mycophenolate mofetil should be stopped 6 weeks prior to conception. The optimal time to conception continues to remain an area of contention. It is important that counseling for childbearing should start as early as prior to getting a kidney transplant and should be done at every clinic visit after transplant. Breast-feeding is not contraindicated and should not be discouraged. This review will help the physicians in medical optimization and counseling of renal transplant recipients of childbearing age.

    Full Text Available Background: Organ transplant recipients can experience serious diseases from infections due to emerging and reemerging parasitic infections. This study was carried out to evaluate the prevalence of intestinal parasites among renal transplant re-cipients of Iran. "nMethods: This cross-sectional study was conducted from June 2003 to August 2004 on renal transplant recipients in Iran. A total of 706 fecal samples obtained from randomly selected population originated from all over Iran. Patient's information was recorded in a questionnaire before sampling. A sample of stool was taken from each person. Direct wet smear exami-nation, formalin-ether concentration, Ziehl-neelsen staining, and agar plate culture were done for each sample. "nResults: Totally 32 patients (4.5% were positive for parasitic infections. In searching for emerging parasitic infections, the most prevalent parasites were found to be Blastocystis hominis, Giardia lamblia and Entamoeba coli, respectively. The merely ova which were seen were related to Hymenolepis nana. With investigation of healthy control, no significant differ-ence was found between transplanted and normal population. "nConclusion: The population showed controlled rate of intestinal infections probably due to regular awareness concerning risks of opportunistic infections; albeit regular surveillance through routine examination of stool samples for parasites seems considerably advantages the transplant recipient patients.

    According to the Australian and New Zealand Dialysis and Transplantation (ANZDATA) 2010 Annual Report, cancer is surpassing cardiovascular diseases as the leading cause of posttransplantation death. Skin cancer and posttransplantation lymphoproliferative disorder (PTLD) are 2 cancers in Western countries. However, urothelial cancer happens much more frequently among Chinese people. We reviewed our experience in Congress of the Asian Society of Transplantation (CAST) 2005, including 10 urothelial cancers, among 620 renal transplant recipients. In this report, we have presented our updated data. From July 1981 to May 2011, we performed 770 renal transplantations followed by graft and native kidney sonography annually even among asymptomatic cases using the protocol described in CAST 2005. During this period, 35 urothelial tumors were detected, ie, 25 new cases were identified in 6 years. These 35 cases included 7 cases with bilateral upper tract involvement and 5 of them with bladder tumors. Seven patients had bladder cancer alone. In 19 patients, 22 ureteral cancers included 1 that grew from the graft ureter, 17 (77.3%) patients showed hydronephrosis by sonography. We performed 13 bilateral nephroureterectomies; 2 were known to have bilateral upper tract cancer. Four of the other 11 were found to have insidious tumors. In contrast, 2 of the 15 initial unilateral nephroureterectomy patients underwent a subsequent contralateral nephroureterectomy due to a tumor. The pattern of urethral cancer in renal transplant recipients is thoroughly different, including female predominance, and a higher incidence of upper tract involvement. We emphasize the necessity of routine periodic sonographic survey even among asymptomatic patients for early detection of a urothelial tumor. Copyright © 2012 Elsevier Inc. All rights reserved.

    The presence of end-stage renal disease (ESRD) has been associated with profound clinical effects on hemostasis ranging from thrombosis to bleeding complications. The pathogenesis of uremic bleeding is multifactorial. It has been attributed to platelet dysfunction, the most important feature, particularly platelet-platelet and platelet-vessel wall interactions. Renal replacement therapy has helped reduce bleeding episodes, but the risk of morbidity and mortality due to hemorrhage persists. Abnormalities of blood coagulation and fibrinolysis predispose uremic patients to hypercoagulable state carrying the risk of atherosclerotic cardiovascular disease and thrombotic complications such as thrombosis of the vascular access wall. There are differences in the measurement of various hemostatic parameters in patients with ESRD concerning treatment with either hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Hemostatic disturbances are overlapped by changes in the coagulation/fibrinolytic system after renal transplantation (RT). Despite the etiology, renal transplant patients are at an increased risk of thromboembolic events as a consequence of prothrombotic clotting and fibrinolytic abnormalities. This hypercoagulable state is to a large extent associated with immunosuppressive drugs. This review will give a summary of views on hemostasis in patients with ESRD and after RT.

  6. Complement Recognition Pathways in Renal Transplantation.

    The complement system, consisting of soluble and cell membrane-bound components of the innate immune system, has defined roles in the pathophysiology of renal allograft rejection. Notably, the unavoidable ischemia-reperfusion injury inherent to transplantation is mediated through the terminal complement activation products C5a and C5b-9. Furthermore, biologically active fragments C3a and C5a, produced during complement activation, can modulate both antigen presentation and T cell priming, ultimately leading to allograft rejection. Earlier work identified renal tubule cell synthesis of C3, rather than hepatic synthesis of C3, as the primary source of C3 driving these effects. Recent efforts have focused on identifying the local triggers of complement activation. Collectin-11, a soluble C-type lectin expressed in renal tissue, has been implicated as an important trigger of complement activation in renal tissue. In particular, collectin-11 has been shown to engage L-fucose at sites of ischemic stress, activating the lectin complement pathway and directing the innate immune response to the distressed renal tubule. The interface between collectin-11 and L-fucose, in both the recipient and the allograft, is an attractive target for therapies intended to curtail renal inflammation in the acute phase.

    Full Text Available A 63-year-old woman presented to the Orthopedic Unit of our hospital complaining of right hip pain of 6 months'duration associated with a worsening limp. Her past medical history included chronic renal insufficiency. Physical examination revealed deep pain in the iliac region and severe restriction of the right hip's articular function in the maximum degrees of range of motion. X-rays and CT scan detected an osteolytic and expansive lesion of the right supra-acetabular region with structural reabsorption of the right iliac wing. 99mTc-MDP whole-body bone scan showed an abnormal uptake in the right iliac region. Bone biopsy revealed an osteolytic lesion with multinucleated giant cells, indicating a brown tumor. Serum intact PTH was elevated (1020 pg/ml; normal values, 12 62 pg/ml, but her serum calcium was normal (total = 9.4 mg/dl, nv 8.5–10.5; ionized = 5.0 mg/dl, nv 4.2–5.4 due to the coexistence of chronic renal failure. 99mTc-MIBI scintigraphy revealed a single focus of sestamibi accumulation in the left retrosternal location, which turned out to be an intrathoracic parathyroid adenoma at surgical exploration. After surgical removal of the parathyroid adenoma, PTH levels decreased to 212 pg/ml. Three months after parathyroidectomy, the imaging studies showed complete recovery of the osteolytic lesion, thus avoiding any orthopedic surgery. This case is noteworthy because (1 primary hyperparathyroidism was not suspected due to the normocalcemia, likely attributable to the coexistence of chronic renal failure; and (2 it was associated with a brown tumor of unusual location (right supra-acetabular region.

    To evaluate the usefulness and complications of renal biopsy under ultrasonography-guidance in renal dysfunction after renal transplantation. Ultrasonography-guided renal biopsy was done in 47 patients with the transplanted kidney. The subjects consisted of 30 males and 17 females, age ranged from 16 to 66 years (average age=38 years). Biopsies were done once in 27 patients, twice in 17 patients, three times in 3 patients, a total of 70 biopsies. The success rate of renal biopsy for the accurate pathologic diagnosis and the incidence and types of complications following biopsy were evaluated. The success rate of renal biopsy for the accurate pathologic diagnosis was 96%(67/70). Pathologic diagnosis included 27 cases of acute rejection (39%), 8 cases of acute tubular necrosis (11%), 4 cases of acute rejection and acute tubular necrosis (6%), 4 cases of cyclosporin toxicity (6%), 4 cases of primary disease recurrence (6%), 4 cases of infection (6%) and others. Complications after renal biopsy included 15 cases of microscopic hematuria (21%), 1 case of gross hematuria with spontaneous cessation and 1 case of life threatening hemorrhage. Ultrasonography-guided renal biopsy is a safe and effective diagnostic method for the evaluation of renal dysfunction following renal transplantation.

    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.

    Full Text Available INTRODUCTION: Kidney transplantation corrects endocrine imbalances. Nevertheless, these early favorable events are not always followed by rapid normalization of parathyroid hormone secretion. A possible deleterious effect of parathyroidectomy on kidney transplant function has been reported. This study aimed to compare acute and longterm renal changes after total parathyroidectomy with those occurring after general surgery. MATERIALS AND METHODS: This was a retrospective case-controlled study. Nineteen patients with persistent hyperparathyroidism underwent parathyroidectomy due to hypercalcemia. The control group included 19 patients undergoing various general and urological operations. RESULTS: In the parathyroidectomy group, a significant increase in serum creatinine from 1.58 to 2.29 mg/dl (P < 0.05 was noted within the first 5 days after parathyroidectomy. In the control group, a statistically insignificant increase in serum creatinine from 1.49 to 1.65 mg/dl occurred over the same time period. The long-term mean serum creatinine level was not statistically different from baseline either in the parathyroidectomy group (final follow-up creatinine = 1.91 mg/dL or in the non-parathyroidectomy group (final follow-up creatinine = 1.72 mg/dL. CONCLUSION: Although renal function deteriorates in the acute period following parathyroidectomy, long-term stabilization occurs, with renal function similar to both preoperative function and to a control group of kidney-transplanted patients who underwent other general surgical operations by the final follow up.

    Objectives: Oral candidiasis (OC) is a frequent oral lesion in renal transplant patients (RTPs). Despite the increased prevalence of OC in RTPs, no study has examined related risk factors. The aims of this study were to analyze the prevalence of and risk factors for OC in RTPs compared with age- and gender-matched healthy control group (HC) as well as determine the incidence of OC after transplantation. Study Design: We analyzed the prevalence and risk factors of OC in a group of 500 RTPs (307 men, 193 women, mean age 53.63 years) and 501 HC subjects (314 men, 187 women, mean age 52.25 years). Demographic and pharmacological data were recorded for all subjects. Incident cases of OC were ascertained retrospectively from outpatient clinical records only in the RTP group. Results: The prevalence of OC was 7.4% in RTPs compared with 4.19% in HC (P<0.03). The most frequent type of OC in the two groups was denture stomatitis. Statistical association was found between OC and age, mycophenolate mofetil dose and blood levels, dentures and tobacco. The multiple logistic regression model only chose for denture variable. According to the outpatient clinical records, 24 RTPs suffered OC during the first moth post-transplant. Severe lesions affecting the oral cavity and pharynx appeared in 79% of the OC cases. Conclusions: This study shows a lower prevalence of OC in RTPs than previous reports. Denture stomatitis was the most frequent OC prevalence form described in RTPs. Severe candidiasis is more frequent in the immediate posttransplant period. The presence of denture is an important risk factor of OC. These results emphasise the importance of adequate pre- and post-transplant oral health and denture cleaning and adjustment is recommended for these subjects to prevent this infection. Key words:Oral candidiasis, immunosuppressive therapy, renal transplantation. PMID:23385511

    The effects of cinacalcet in persistent and/or hypercalcaemia-associated secondary hyperparathyroidism (SHPT) have been described in patients on dialysis. To evaluate the efficacy and safety of cinacalcet in SHPT not on dialysis and its effects on bone turnover markers. Non-randomised, longitudinal, observational, analytical study of patients with chronic kidney disease (CKD) and SHPT (PTH> 80 pg/mL) as well as normo- or hypercalcaemia (≥8.5mg/dL), treated with cinacalcet. Mean cinacalcet dose was 30mg/day in 66.7%. We studied 15 patients (10 women), aged 66.0±17.93years. The aetiology was unknown in 20% of cases. Sociodemographic variables and renal function parameters were recorded. We compared values at baseline as well as after 6 and 12 months. Calcium (10.3±0.55 vs. 9.4±1.04) and iPTH (392.4±317.65 vs. 141.8±59.26) levels decreased. Increased levels of phosphorus (3.7±1.06 vs. 3.9±0.85) and ß-CTX (884.2±797.22 vs. 1053.6±999.00) were detected, although there were no significant changes in GFR, urinary calcium or other bone markers. Two patients withdrew from the study (gastrointestinal intolerance and parathyroidectomy, respectively). Cinacalcet at low doses is effective in the management of SHPT in CKD patients who are not on dialysis. Its use reduces iPTH and calcaemia, without causing serious side effects or significant changes in renal function. Copyright © 2015 Sociedad Española de Nefrología.

    Full Text Available Renal transplantation has evolved as the best treatment option for patients with end-stage renal disease. Different oral problems arise in these patients, either as a direct consequence of drug-induced immunosuppression or pharmacokinetics. To determine the prevalence of intra-oral lesions in a group of medically stable Saudi renal transplant patients (RTP and to identify possible risk factors, in comparison with age and sex-matched healthy control subjects (HCS, we studied 58 RTP and 52 HCS. All subjects had a thorough oral examination and oral lesions were diagnosed according to the clinically accepted criteria. Gingival overgrowth (GO, erythematous candidiasis (EC and hairy leukoplakia (HL were diagnosed in RTP with prevalence of 74.1%, 15.5%, and 8.6%, respectively. The severity of the gingival overgrowth significantly correlated with the use of cyclosporine and nifedipine combination therapy, serum cyclosporine, and serum creatinine level. In conclusions, the finding of our study strongly propose that RTP should undergo routine and regular comprehensive oral examination, and any suspicious lesion must be investigate and treated.

    End-stage kidney disease (ESKD) is one of the most prevalent diseases in the world with significant morbidity and mortality. Current modes of renal replacement therapy include dialysis and renal transplantation. Although dialysis is an acceptable mode of renal replacement therapy, it does have its shortcomings, which include poorer life expectancy compared with renal transplantation, risk of infections and vascular thrombosis, lack of vascular access and absence of biosynthetic functions of the kidney. Renal transplantation, in contrast, is the preferred option of renal replacement therapy, with improved morbidity and mortality rates and quality of life, compared with dialysis. Renal transplantation, however, may not be available to all patients with ESKD. Some of the key factors limiting the availability and efficiency of renal transplantation include shortage of donor organs and the constant risk of rejection with complications associated with over-immunosuppression respectively. This review focuses chiefly on the potential roles of bioengineering in overcoming limitations in renal transplantation via the development of cell-based bioartificial dialysis devices as bridging options before renal transplantation, and the development of new sources of organs utilizing cell and organ engineering.

    The primary objective of this study was to compare the pharmacokinetics of dexmedetomidine in patients with end-stage renal failure and secondary hyperparathyroidism with those in normal individuals. Fifteen patients with end-stage renal failure and secondary hyperparathyroidism (Renal-failure Group) and 8 patients with normal renal and parathyroid gland function (Control Group) received intravenous 0.6 μg/kg dexmedetomidine for 10 minutes before anaesthesia induction. Arterial blood samples for plasma dexmedetomidine concentration analysis were drawn at regular intervals after the infusion was stopped. The pharmacokinetics were analysed using a nonlinear mixed-effect model with NONMEM software. The statistical significance of covariates was examined using the objective function (-2 log likelihood). In the forward inclusion and backward deletion, covariates (age, weight, sex, height, lean body mass [LBM], body surface area [BSA], body mass index [BMI], plasma albumin and grouping factor [renal failure or not]) were tested for significant effects on pharmacokinetic parameters. The validity of our population model was also evaluated using bootstrap simulations. The dexmedetomidine concentration-time curves fitted best with the principles of a two-compartmental pharmacokinetic model. No covariate of systemic clearance further improved the model. The final pharmacokinetic parameter values were as follows: V1  = 60.6 L, V2  = 222 L, Cl1  = 0.825 L/min and Cl2  = 4.48 L/min. There was no influence of age, weight, sex, height, LBM, BSA, BMI, plasma albumin and grouping factor (renal failure or not) on pharmacokinetic parameters. Although the plasma albumin concentrations (35.46 ± 4.13 vs 44.10 ± 1.12 mmol/L, respectively, P Renal-failure Group than in the Control Group (81.68 ± 18.08 vs 63.07 ± 13.45 μg/kg/min, respectively, P renal failure and hyperparathyroidism were similar to those in patients with normal renal function.

    The aim of our study was to evaluate the rate of surgical complications, patient outcomes, and impact on graft function in renal transplant recipients in whom cholecystectomy for acute cholecystitis was performed. We reviewed data on transplant patients from January 1, 2006, to December 31, 2013. The subgroup of patients who required subsequent cholecystectomy for acute cholecystitis was assessed, and their data were further analyzed. Thirty-one patients who underwent cholecystectomy for acute cholecystitis after renal transplantation were included in the study. Clinical signs such as pain in the right upper quadrant, temperature >38°C, and elevation in bilirubin levels occurred in 20 (64.5%), 8 (25.8%), and 3 (9.7%) patients, respectively. Ultrasound signs of acute cholecystitis were present in 27 patients (87.1%). In terms of laboratory values, white blood cell counts >10 × 10(9)/L occurred in 17 patients (54.8%), and C-reactive protein levels >40 mg/L were reported in 21 patients (67.7%). The conversion rate to open surgery was 32.3% (10 patients). In 13 cases, acalculous cholecystitis was present (41.9%). The average serum creatinine level 1 year after cholecystectomy had no statistically significant differences. One patient required temporary dialysis during the postoperative period (with subsequent graft recovery), and 1 graft was lost. Acute cholecystitis in kidney transplant recipients is a serious complication, with frequent difficulties related to evaluation and diagnosis. Because clinical signs could be very mild compared with severity of gallbladder affliction, there is little room if any for conservative treatment in these patients. We have not noticed adverse impact of acute cholecystitis on 1-year graft function. Copyright © 2016 Elsevier Inc. All rights reserved.

    Renal transplantation in HIV-positive patients with end-stage renal disease has in recent years become a successful treatment option. We report two patients who underwent renal transplantation using a combination of basiliximab, calcineurin inhibitors, mycophenolate mofetil (MMF), and steroids with a "non-interacting" antiretroviral combination therapy consisting of stavudine or abacavir, lamivudine, and nevirapine. We observed no acute rejection but a BK polyomavirus infection in both patients. In conclusion, a quadruple immunosuppression with an interleukin 2 receptor antagonist, a calcineurin inhibitor, MMF, and steroids appears to be advisable to prevent high rates of acute rejection, but if possible thereafter immunosuppression should be tapered rapidly (eg, MMF stop, prednisolone dose 5 mg/d). The selection of antiretroviral agents should avoid compounds that interact severely with the immunosuppression used. Copyright © 2015 Elsevier Inc. All rights reserved.

    Sonographically guided percutaneous core biopsy of renal allografts has been performed for decades, providing valuable information in monitoring the status of normally functioning renal transplants as well as investigating the cause of renal transplant dysfunction. This article reviews practical aspects of biopsy technique using the cortical tangential approach, with consideration of factors that may influence biopsy success, including selection of biopsy device. Clinically important complications from renal transplant biopsy are uncommon; the most recent experience for one institution is analyzed in the context of existing evidence regarding the frequency and timing of these major complications, to understand pragmatic implications for peri-procedural care.

    Renal transplantation is the treatment of choice for patients with chronic renal failure, which produces a dramatic improvement in the quality of life and survival rates, in comparison to long-term dialysis. Nowadays, new imaging modalities allow early diagnosis of complications, and thanks to the recent developments of interventional techniques, surgery may be avoided in most cases. Knowledge in the types of renal transplant complications is fundamental for a correct pre-operative planning. In this article, we described the most common or clinically relevant renal transplant complications and explained their interventional management.

    Full Text Available In some renal allograft recipients, anemia persists or develops following transplantation. Anemia is associated with pre-operative blood loss and allograft dysfunction, including delayed graft function, acute rejection and chronic allograft dysfunction. To study the prevalence and association of post-renal transplant anemia, we studied 200 renal transplant recipients; 131 (65.5% patients were males and 69 (34.5% patients were females, and age ranged from 17 to 67 years, with a mean of 37.7 ± 10.8 years. All patients were receiving cyclosporine, prednisolone and mycophenolate mofetil (MMF. Complete blood count was done at two times: three and six months post-renal transplant. There were 74% anemic patients three months after renal transplantation and 45% anemic patients six months after renal transplantation. High creatinine value, female gender, delayed graft function, episodes of acute rejection, perioperative blood loss and infections were the only significant independent risk factors for prevalence of anemia post-renal transplant. In our study, we did not find an association between MMF and cyclosporine nor angiotensin-converting enzyme inhibitors (ACEIs or angiotensin receptors blocker (ARBs with anemia. This study demonstrates that anemia is a common complication during the first six months after kidney transplantation, with several risk factors precipitating this complication.

    Patients who undergo dialysis treatment or a renal transplant have a high risk of blood-borne viral infections, including the Torque teno virus (TTV). This study identified the presence of TTV and its genome groups in blood samples from 118 patients in dialysis and 50 renal-transplant recipients. The research was conducted in a hospital in the city of Maringá, state of Paraná. The viral DNA, obtained from whole blood, was identified by using two nested Polymerase Chain Reactions (PCR). The frequencies of TTV were 17% and 36% in dialysis patients using the methodology proposed by Nishizawa et al . (1997) and Devalle and Niel (2004) , respectively, and 10% and 54% among renal-transplant patients. There was no statistically significant association between the frequency of the pathogen and the variables: gender, time in dialysis, time since transplant, blood transfusions, and the concomitant presence of hepatitis B, for either the dialysis patients or the renal-transplant recipients. Among dialysis patients and renal-transplant recipients, genogroup 5 was predominant (48% and 66% respectively), followed by genogroup 4 (37% and 48%) and genogroup 1 (23% and 25%). Genogroup 2 was present in both groups of patients. Some patients had several genogroups, but 46% of the dialysis patients and 51% of the renal-transplant recipients had only a single genogroup. This study showed a high prevalence of TTV in dialysis patients and renal-transplant recipients.

    Percutaneous needle core biopsy is the definitive procedure by which essential diagnostic and prognostic information on acute and chronic renal allograft dysfunction is obtained. The diagnostic value of the information so obtained has endured for over three decades and has proven crucially important in shaping strategies for therapeutic intervention. This Review provides a broad outline of the utility of performing kidney graft biopsies after transplantation, highlighting the relevance of biopsy findings in the immediate and early post-transplant period (from days to weeks after implantation), the first post-transplant year, and the late period (beyond the first year). We focus on how biopsy findings change over time, and the wide variety of pathological features that characterize the major clinical diagnoses facing the clinician. This article also includes a discussion of acute cellular and humoral rejection, the toxic effects of calcineurin inhibitors, and the widely varying etiologies and characteristics of chronic lesions. Emerging technologies based on gene expression analyses and proteomics, the in situ detection of functionally relevant molecules, and new bioinformatic approaches that hold the promise of improving diagnostic precision and developing new, refined molecular pathways for therapeutic intervention are also presented.

    Growth hormone (GH) improves growth in children with chronic renal failure. The response to GH may be affected by the degree of secondary hyperparathyroidism and concurrent treatment with vitamin D. Forty-six rats underwent 5/6 nephrectomy (Nx) and were given a high-phosphorus diet (Nx-Phos) to induce advanced secondary hyperparathyroidism and divided into the following groups: (1) Nx-Phos (n = 10) received saline, (2) GH at 10 IU/kg per d (Nx-Phos+GH; n = 9), (3) GH and daily calcitriol (D) at 50 ng/kg per d (Nx-Phos+GH+daily D; n = 8), (4) GH and intermittent D (three times weekly) at 350 ng/kg per wk (Nx-Phos+GH+int D; n = 9), and (5) intact-control (n = 10). Serum parathyroid hormone (PTH) levels were elevated in Nx-Phos, but IGF-I levels did not change with growth hormone. Body length, tibial length, and growth plate width did not increase with either GH or calcitriol. Proliferating cell nuclear antigen staining, PTH/PTHrP receptor, bone morphogenetic protein-7, and fibroblast growth factor receptor-3 expression increased with GH alone or with intermittent calcitriol but were slightly diminished during daily calcitriol administration. GH enhanced IGF-I, IGF binding receptor-3, and GH receptor but declined with daily and intermittent calcitriol. Overall, there was no improvement in body length, tibial length, and growth plate width at the end of GH therapy, but selected markers of chondrocyte proliferation and chondrocyte differentiation increased, although these changes were attenuated by calcitriol. The combination of GH and calcitriol that is frequently used in children with renal failure and secondary hyperparathyroidism require further studies to evaluate the optimal dose and frequency of administration to increase linear growth and prevent bone disease.

    A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used. Although considered to be accompanied with risks of bleeding, bowel injury, and renal dysfunction, PNL is effective for urinary lithiasis after renal transplantation. TUL is less invasive, but access may be difficult when the ureter has an unusual course or ureteral stricture exists, as in our patient.

Rarely may allograft be nonfunctional from the beginning, or anuria is noted after a period of good urine output. Surgical causes for anuria should be high on the differential diagnosis in immediate-to-early posttransplant period, especially in an unsensitized recipient. We present two unusual causes of early onset anuria after living related renal transplantation where early surgical reexploration salvaged renal allografts with excellent long term outcomes.

    2003-05-01

    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

    Melanoma risk factors and incidence in renal transplant recipients can inform decision making for both patients and clinicians. To determine risk factors and characteristics of renal transplant recipients who develop melanoma. This cohort study of a large national data registry used a cohort of renal transplant recipients from the United States Renal Data System (USRDS) database from the years 2004 through 2012. Differences in baseline characteristics between those who did and did not develop melanoma were examined, and a survival analysis was performed. Patients with renal transplants who received a diagnosis of melanoma according to any inpatient or outpatient claim associated with a billing code for melanoma were included. A history of pretransplant melanoma, previous kidney transplantation, or transplantation after 2012 or before 2004 were exclusion criteria. The data analysis was conducted from 2015 to 2016. Receipt of a renal transplant. Incidence and risk factors for melanoma. Of 105 174 patients (64 151 [60.7%] male; mean [SD] age, 49.6 [15.3] years) who received kidney transplants between 2004 and 2012, 488 (0.4%) had a record of melanoma after transplantation. Significant risk factors for developing melanoma vs not developing melanoma included older age among recipients (mean [SD] age, 60.5 [10.2] vs 49.7 [15.3] years; P melanoma in USRDS patients compared with Surveillance, Epidemiology, and End Results patients across all years was 4.9. A Kaplan-Meier estimate of the median time to melanoma among those patients who did develop melanoma was 1.45 years (95% CI, 1.31-1.70 years). Renal transplant recipients had greater risk of developing melanoma than the general population. We believe that the risk factors we identified can guide clinicians in providing adequate care for patients in this vulnerable group.

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

    Balkan endemic nephropathy (BEN) is a chronic tubulointerstitial disease prevalent in Croatia, Romania, Bulgaria, Bosnia and Herzegovina, and Serbia. In addition to renal disease, an increased incidence of upper urothelial carcinomas (UUCs) has been observed in the foci of BEN. Carcinoma may occur alone or in combination with BEN. Immunosuppression is associated with an increased risk for development of different malignancies. There are no data in the literature about the outcome of patients with BEN after transplantation. We performed a retrospective evaluation of the database and review of the charts and pathology reports of 601 renal transplant recipients treated at our institution. From January 1995 to December 2004, kidney transplantations were performed in nine patients with BEN. One-year graft survival was 100%. A man, who was transplanted in 1997 died 2 years after transplantation with a functioning graft due to disseminated cancer from the pelvis of his own kidney. A female patient developed UCC 2 years after transplantation. They were both treated with a bolus of methylprednisolone before transplantation, because of four HLA-mismatches. A male patient developed UCC in the native and transplanted kidneys. He underwent a native nephroureterectomy with partial nephroureterectomy of transplanted kidney. His graft function was preserved with decreased immunosuppression. Three years later a urinary bladder carcinoma was discovered on a regularly performed multislice computed tomography. One patient developed a skin malignancy. Other patients have had uneventful posttransplantation courses with excellent graft function. Thus, 33.3% of patients with BEN developed UUC, compared with a 0.67% prevalence of urinary tract tumors among transplanted patients with other causes of end-stage renal disease. Patients with BEN are at increased risk for the development of UCC after transplantation. Regular screening for early detection of malignancy is mandatory. Longer follow

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

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    A 59-year-old woman with end-stage renal disease of diabetic nephropathy who had been on maintenance hemodialisis for 4 years, underwent a living-unrelated renal transplantation 6 years ago. She was admitted to our hospital, because of a low grade fever and edema. Ultrasonography revealed the cyst with heterogeneity structure in the upper pole of the transplanted kidney. Magnetic resonance imaging showed a high-intensity cystic mass measuring 68×53 mm. As fever and laboratory data did not improve sufficiently by the treatment with antibiotics, echo-guided puncture and drainage were performed for the abnormal structure in the upper pole of the transplanted kidney. In the culture of the purulent aspirate drained from renal cyst, Escherichia coli was isolated. To our knowledge, this is the first report of infected renal cyst of the graft in a renal transplant recipient in the world.

  5. Late renal dysfunction in adult survivors of bone marrow transplantation

    Until recently long-term renal toxicity has not been considered a major late complication of bone marrow transplantation (BMT). Late renal dysfunction has been described in a pediatric population status post-BMT which was attributable to the radiation in the preparatory regimen. A thorough review of adults with this type of late renal dysfunction has not previously been described. Fourteen of 103 evaluable adult patients undergoing allogeneic (96) or autologous (7) bone marrow transplantation, predominantly for leukemia and lymphomas, at the Medical College of Wisconsin (Milwaukee, WI) have had a syndrome of renal insufficiency characterized by increased serum creatinine, decreased glomerular filtration rate, anemia, and hypertension. This syndrome developed at a median of 9 months (range, 4.5 to 26 months) posttransplantation in the absence of specific identifiable causes. The cumulative probability of having this renal dysfunction is 20% at 1 year. Renal biopsies performed on seven of these cases showed the endothelium widely separated from the basement membrane, extreme thickening of the glomerular basement membrane, and microthrombi. Previous chemotherapy, antibiotics, and antifungals as well as cyclosporin may add to and possibly potentiate a primary chemoradiation marrow transplant renal injury, but this clinical syndrome is most analogous to clinical and experimental models of radiation nephritis. This late marrow transplant-associated nephritis should be recognized as a potentially limiting factor in the use of some intensive chemoradiation conditioning regimens used for BMT. Some selective attenuation of the radiation to the kidneys may decrease the incidence of this renal dysfunction.

    The purpose of our study is to compare pregnancy outcomes between women with a functioning renal transplant and women with end-stage renal disease (ESRD). We carried out a population-based retrospective cohort study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2006 to 2011. Logistic regression analysis was used to estimate the age-adjusted effect of functioning renal transplant vs. ESRD requiring dialysis on pregnancy outcomes. We identified 264 birth records to women with a functional renal transplant and 267 birth records to women with ESRD on dialysis among 5,245,452 births. As compared to women with ESRD on dialysis, renal transplant recipients were less likely to have placental abruption [odds ratio, OR 0.23 (95% confidence interval, CI 0.08-0.70)], to receive blood transfusions [OR 0.17 (95% CI 0.09-0.30)], and to have growth-restricted and small-for-gestational-age babies [OR 0.45 (95% CI 0.23-0.85)]. Renal transplant recipients were more likely to have an instrumental delivery [OR 15.38 (95% CI 1.92-123.3)]. Among renal transplant women, there was a trend towards delivery by cesarean section as compared to patients with ESRD [OR 1.31 (95% CI 0.93-1.85)]. However, these results were not statistically significant. Fetal deaths were less likely to occur in women with a renal transplant [OR 0.41 (95% CI 0.17-0.96)]. There were four maternal deaths among patients with ESRD on dialysis and no maternal deaths among renal transplant patients. Patients with a functional renal graft had an overall lower rate of morbidity and adverse pregnancy complications when compared to patients with ESRD on dialysis.

  7. Risk Factors for Chronic Renal Insufficiency Following Cardiac Transplantation.

    2015-09-29

    Although previous publications have discussed kidney disease in nonrenal solid-organ transplantation, none has reviewed thoroughly the potential predictors of long-term renal impairment in cardiac recipients. Thus, the purpose of this review article is to summarize the current state of knowledge on risk factors of chronic renal insufficiency in heart transplant patients. An English language Medline literature search (1946-April 2014) was conducted using the search terms renal insufficiency, kidney failure, kidney diseases, nephrotoxi$ ($ for truncation), creatinine, glomerular filtration rate, heart transplantation and organ transplantation. Additional references were identified from a review of literature citations. A total of 74 articles discussing key risk factors were included in the manuscript.         The existing literature reveals that several recipient characteristics (age, female sex, pretransplant/early post-transplant kidney impairment, diabetes, and hypertension) increase the risk of renal insufficiency after transplantation. Current data also indicate that, while cyclosporine and tacrolimus are most likely major determinants of post-transplant kidney failure, the effects of calcineurin inhibitor doses and concentrations remain unclear. A small number of studies suggest that tacrolimus could possibly induce less nephrotoxicity than cyclosporine, but meta-analyses of randomized controlled trials show the opposite with comparable incidences of dialysis after cardiac transplantation. Finally, the role of genetic variations has only been explored to a limited extent in heart transplant patients. This growing body of evidence should ultimately lead to a better risk prediction regarding chronic renal insufficiency following cardiac transplantation and a more personalized tailoring of immunosuppressive regimens.

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

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

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

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

    To examine the hormonal regulation of the ATP-dependent Ca{sup 2+} pump in the kidneys, the ATP-dependent Ca{sup 2+} uptake by the basolateral membrane vesicles in the renal cortex was measured using radioactive calcium ({sup 45}Ca{sup 2+}) in rats with vitamin D deficiency or rats undergoing thyroparathyroidectomy. The V{sub max} of the Ca{sup 2+} pump activity was increased not only by administering calcitriol, but also by normalizing the serum calcium level in vitamin D-deficient rats. PTH suppressed the Ca{sup 2+} pump activity in normocalcemic vitamin D-deficient rats. Thyroparathyroidectomy did not affect the Ca{sup 2+} pump activity in the kidneys of normal rats. It was concluded that the ATP-dependent Ca{sup 2+} pump activity was depressed by secondary hyperparathyroidism in vitamin D-deficient rats. (author).

    To explore donor and recipient experiences of stressors and coping mechanisms associated with live-related renal transplantation. Live-related renal transplantation is an effective and efficient treatment for end-stage kidney disease, but is also associated with a variety of stressors. Longitudinal, phenomenological study. Eleven live kidney donors and their recipients (n = 22) were recruited from a regional renal transplant centre in South-West England. Data were collected through three recorded, semi-structured interviews, conducted pretransplant and at three and 10 months post-transplant. Interviews were transcribed verbatim, analysed using a process of thematic analysis and validated through a constructive process of inter-rater reliability. End-stage kidney disease, dialysis and live transplantation produced a variety of stressors for donors and recipients. Common stressors included the live transplantation decision-making process, the prospect of surgery and postoperative recovery, follow-up care for donors and, in particular, concern for each other, especially amongst recipients. The main stressor, however, was fear of transplant failure. Participants used a variety of problem- and emotion-focused coping mechanisms to deal with these stressors and donors and recipients actively supported each other through the transplantation process. Renal transplantation remains the treatment of choice for most patients with end-stage kidney disease but is a source of considerable stress for donors and especially recipients and subsequently requires a range of coping mechanisms, including social support. Patients need to be adequately informed of the risks associated with transplantation and provided with appropriate emotional care and support throughout the transplantation process. Health professionals also need to be mindful of assessing the needs and managing realistic expectations of patients and their families. © 2012 Blackwell Publishing Ltd.

    Hyperuricemia is a common adverse event frequently found in renal transplant recipients with mizoribine (MZ). Hyperuricemia itself will be a cause of renal dysfunction, and renal dysfunction also will be a cause of hyperuricemia simultaneously. This study investigates frequency of hyperuricemia and renal failure in renal transplant recipients treated with high-dose MZ. From December 2007 to October 2015, there was a total of 32 living related renal transplant recipients treated with high-dose MZ. Of the 32 patients, 28 were treated with urate-lowering medications. One patient received allopurinol (AP) and 13 patients received benzbromarone (BB). For 6 of them, their urate-lowering medications were converted to febuxostat (FX) form AP or BB. In the remaining 14 patients, FX was administered from the beginning. In 2 cases of ABO-incompatible living related renal transplant recipients who were maintained with high-dose MZ and BB, severe hyperuricemia and acute renal failure occurred. One patient was a 48-year-old man, and his creatinine (Cr) level increased to 8.14 mg/dL and his serum uric acid (UA) was 24.6 mg/dL. Another patient was a 57-year-old man, and his Cr level increased to 3.59 mg/dL and his UA was 13.2 mg/dL. In both cases Cr and UA were improved, and no finding of acute rejection and drug toxicity was observed in graft biopsy specimens. BB was switched to FX and discontinuance or reduction of MZ was done. Combination of MZ and BB has the risk of acute renal dysfunction after renal transplantation. Latent renal dysfunction should be watched for in renal transplant recipients receiving high-dose MZ. Copyright © 2016 Elsevier Inc. All rights reserved.

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

    LENUS (Irish Health Repository)

    Phelan, P J

    2012-02-01

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

    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.

    Total parathyroidectomy with autotransplantation (TPTX + AT) and subtotal parathyroidectomy (SPTX) have been recommended to patients with renal hyperparathyroidism (RHPT).But which one is the best surgical method remains controversial. The aim of the present study was to compare the two surgical procedures with respect to long-term outcomes. A literature search was undertaken using Medline, EMBASE, CNKI and CBM from inception to May 2015. Study quality was assessed using the Newcastle-Ottawa Scale. Data were analyzed using Review Manager version 5.1.0. A total of 13 studies comprising 1589 patients with renal failure were identified. There was no statistically significant difference in the rate of symptomatic improvement (OR 0.77; 95%CI 0.22 to 2.69; P = 0.68), radiological success (OR 0.17; 95%CI 0.02 to 1.56; P = 0.90), hyperparathyroidism recurrence or persistence (OR 1.31; 95%CI 0.65 to 2.65; P = 0.45) and reoperation (OR 1.55; 95%CI 0.62 to 3.86; P = 0.35) between TPTX + AT and SPTX. The effects on serum calcium and parathyroid hormone (PTH) were similar between two surgical protocols. Both the TPTX + AT and SPTX were effective in treating RHPT and preventing recurrence. The difference between the two surgeries in recurrence or persistence and reoperation rate was insignificant. Further prospective, randomized controlled trials with high statistic power are necessary to comparative the two surgeries on the long term safety. © 2016 Asian Pacific Society of Nephrology.

    Renal failure causes morbidity and mortality after lung transplantation and is aggravated by exposure to nephrotoxic immunosuppressant (IS) drugs. We report an off-label experience using belatacept for lung transplant recipients with severe renal insufficiency to reduce nephrotoxic IS exposure. We analyzed data retrospectively from a consecutive series of lung transplant patients with renal insufficiency in whom belatacept treatment was initiated between June 2012 and June 2014 at the University of Maryland Medical Center. Eight patients received belatacept because of acute or chronic renal insufficiency (median) GFR 24 (IQR 18-26). Glomerular filtration rate (GFR) remained stable in two patients and increased in five. One patient with established renal and respiratory failure received only the induction dose of belatacept and died 4 months later of respiratory and multisystem organ failure. Calcineurin inhibitor or sirolimus exposure was safely withheld or reduced without moderate or severe acute rejection during ongoing belatacept in the other seven patients. FEV1 remained stable over the 6-month study interval. Belatacept use appears to permit safe transient reduction in conventional immunosuppressive therapy and was associated with stable or improved renal function in a small retrospective series of lung transplant recipients with acute or chronic renal insufficiency. © 2015 Steunstichting ESOT.

    To describe our initial experience in the treatment of hyperparathyroidism (HPP) of renal cause using total or subtotal parathyroidectomy, autoimplant and cryopreservation in pediatric patients. Secondary HPP is the increased function of the parathyroid hormone (PTH) due to an abnormal phosphocalcic metabolism in patients with chronic renal failure (CRF). This situation produces increased bone resorption resulting in osteodystrophy and endovascular calcifications. Surgical treatment is aimed to diminish the level of PTH in CRF patients, to avoid HPP complications. Descriptive, monocentric and retrospective study of a case series of patients with secondary and tertiary hyperparathyroidism, who went through total or subtotal parathyroidectomy, autoimplant and cryopreservation between 2009 and 2016. We analyzed the following variables: age, calcemia, PTH, phosphatemia, alkaline phosphatase (ALP), follow-up and complications. The continuous variables are expressed in median and interquartile range or in mean and SD, according to their distribution. The categorical variables were expressed in percentages and frequencies (repeated sentence). Number of patients included: 13. Mean age of the patients was 16.7 years old. Preoperative median calcium dosage was 9.1 mg/dl (IQR: 8.9-9.5). Median PTH was 2,600 pg/ml (IQR: 1,400 pg/ml to 2,785 pg/ml). Intraoperatory dosage of PTH reported a median drop of 86.6% in the first 15 minutes (IQR: 80.5-95.9). After the first 48 hours, median calcemia was 9 mg/dl (IQR: 7.7-9.4) and median PTH was 40 pg/ml (IQR: 20-113). We did not identify intraoperatory complications. In the immediate post operatory stage, mean IV calcium therapy was 4 days (SD: 2.39). Median time of follow-up was 18 months (IQR 9-36). Two patients had hungry bone syndrome and one patient had a recurrence of the pathology as remote post operatory complications. After a year, median calcemia, was 9 mg/dl (IQR: 7.6-9.3) and median PTH was 50 pg/ml (IQR: 28.5-108). The

    Nowadays, nephron sparing surgery for renal carcinoma achieves good oncological results, similar to radical surgery, with the advantage of preserving renal function. Renal cell carcinomas appear de novo in 4.6% of post-transplant patients compared with 3% of tumors in the general population, affecting less than 10% to renal allograft. The purpose is to analyze our experience and make a literature review about the role of nephron sparing surgery to treat de novo renal tumours in renal grafts. A retrospective and descriptive analysis has been realized, finding four patients who presented with de novo renal tumours over renal graft after kidney transplantation and treated by nephron sparing surgery. A Medline review is done to search similar series published. Oncological and functional results were reviewed and analyzed. We worked with SPSS 12.0 software. Medium age at diagnosis was 46.5 y (42-62). Medium size was 2.4cm. (1.5-3.5) and final histology showed medium tumours size of 3.0cm. (1.7-3.5). Medium hospital stay was 6.0d. Medium time from transplantation to diagnosis was 92 months (42-192). NSS was done in all cases, in 3 cases tumorectomy and one partial nephrectomy. Transfusion was only needed in one case. All cases had pT1aN0M0 RCC histology exam. Renal function did not change from preoperative. All patients are free of progression with a medium follow-up of 46.5 months (15-58). NSS could be an option to treat graft tumours in selected cases, preserving renal function. In our experience, is a safe and efficient treatment in patients with small de novo renal tumours over renal graft.

    Hyperparathyroidism is a common endocrine disorder with potential complications on the skeletal, renal, neurocognitive and cardiovascular systems. While most cases (95%) occur sporadically, about 5% are associated with a hereditary syndrome: multiple endocrine neoplasia syndromes (MEN-1, MEN-2A, MEN-4), hyperparathyroidism-jaw tumour syndrome (HPT-JT), familial hypocalciuric hypercalcaemia (FHH-1, FHH-2, FHH-3), familial hypercalciuric hypercalcaemia, neonatal severe hyperparathyroidism and isolated familial hyperparathyroidism. Recently, molecular mechanisms underlying possible tumour suppressor genes (MEN1, CDC73/HRPT2, CDKIs, APC, SFRPs, GSK3β, RASSF1A, HIC1, RIZ1, WT1, CaSR, GNA11, AP2S1) and proto-oncogenes (CCND1/PRAD1, RET, ZFX, CTNNB1, EZH2) have been uncovered in the pathogenesis of hyperparathyroidism. While bi-allelic inactivation of CDC73/HRPT2 seems unique to parathyroid malignancy, aberrant activation of cyclin D1 and Wnt/β-catenin signalling has been reported in benign and malignant parathyroid tumours. Clinicopathological correlates of primary hyperparathyroidism include parathyroid adenoma (80-85%), hyperplasia (10-15%) and carcinoma (hyperparathyroidism generally presents with diffuse parathyroid hyperplasia, whereas tertiary hyperparathyroidism reflects the emergence of autonomous parathyroid hormone (PTH)-producing neoplasm(s) from secondary parathyroid hyperplasia. Surgical resection of abnormal parathyroid tissue remains the only curative treatment in primary hyperparathyroidism, and parathyroidectomy specimens are frequently encountered in this setting. Clinical and biochemical features, including intraoperative PTH levels, number, weight and size of the affected parathyroid gland(s), are crucial parameters to consider when rendering an accurate diagnosis of parathyroid proliferations. This review provides an update on the expanding knowledge of hyperparathyroidism and highlights the clinicopathological correlations of this prevalent

    Full Text Available Purpose. To evaluate the efficacy of percutaneous transluminal angioplasty (PTA in the management of arterial stenosis located close to the allograft anastomosis (close-TRAS. Materials and Methods. 31 patients with renal transplants were admitted to our institution because of persistent hypertension and impairment of transplant renal function and underwent angiography for vascular investigation. 27 were diagnosed suffering from transplant renal artery stenosis (TRAS, whereas 4 had severe iliac artery stenosis proximal to the transplant anastomosis (Prox-TRAS. 3 cases of TRAS coexisted with segmental renal arterial stenosis, whereas 3 other cases of TRAS were caused by kinking and focal stenosis in the middle of the transplanted renal artery. Results. Angioplasty and stenting were successfully applied to all patients with iliac artery stenosis as well as to those with TRAS and segmental artery stenosis. Two of three patients with kinking were well treated with angioplasty and stenting, whereas one treated only with angioplasty necessitated surgery. No major procedure-related complications appeared, and the result was decrease of the serum creatinine level and of the blood pressure. Conclusions. PTA is the appropriate initial treatment of TRAS and close-TRAS, with low morbidity and mortality rates, achieving improvement of graft function and amelioration of hypertension.

    Because of the shortage of deceased donor kidneys, some patients are on dialysis for over 10 years before renal transplantation. Many of these patients are anuric. We reviewed the urological complications in renal transplant recipients with anuria on hemodialysis for more than 10 years, compared with preemptive transplant recipients. The records of 4012 renal transplants from January 1988 to September 2007 were retrospectively reviewed. A total of 2735 deceased donor transplants were performed during this period. We identified a group of patients who were on hemodialysis for over 10 years and made less than 500 mL of urine per day. We compared the rate of urologic complications in this group with patients who were never on dialysis and had normal bladder function based on history and physical examination. Seventy-two patients met the strict inclusion criteria. There were 41 recipients in the anuric group and 31 recipients in the preemptive group. The surgical complications were not significantly different between the two groups (P=0.503). However, the anuric group required five more hospital admissions for complicated urinary tract infections (P=0.044). Renal transplant recipients who have been anuric for a prolonged period have higher rates of complicated urinary tract infections, but the long-term risks of urological complications are not significantly different.

    Elderly patients are the fastest-growing group in need of renal transplantation. This study puts focus on renal transplant recipients in their 80th year or longer at time of engraftment. Is there evidence to support an absolute upper age limit for renal transplantation? Recipients in their 80th year or longer, transplanted between 1983 and 2015, were included. Data were retrieved from the Norwegian Renal Registry in the end of October 2015. Graft and patient survivals were compared with recipients aged 70 to 79 years at transplantation. Forty-seven patients older than 79 years were transplanted in the defined period. Median age 80.1 years, 81% were men. Median time on dialysis before transplantation was 18.5 months. All patients received an allograft from a deceased donor (median donor age, 61.8 years). In the death-censored graft survival model, there was no statistical difference between the groups. We found improved patient and graft survivals after introduction of mycophenolate mofetil and induction with basiliximab. Patients transplanted before 2000 had increased risk of death compared with those transplanted after 2000 (hazard ratio, 3.2; 95% confidence interval, 1.2-8.7). Median uncensored graft survival for patients transplanted after the year 2000 was 5.0 year (95% confidence interval, 2.4-7.6). Median patient survival was 5.0 years (3.1-6.9) and 5-year patient survival was 55%. Age by itself should not be an absolute contraindication against renal transplantation. An estimated 5-year survival rate of 55% post-engraftment for an 80-year-old patient is in our opinion more than acceptable.

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

    Full Text Available Background: Autosomal-dominant polycystic kidney disease (ADPKD, a common hereditary disease, is characterized by the progressive development and enlargement of multiple cysts in both kidneys, and typically resulting in end stage renal disease (ESRD by the fifth decade of life. Post-transplant diabetes mellitus (PTDM, a common complication after transplantation with an incidence rate of 2.5-20%, is associated with poor graft and patient survival. In few studies, PTDM has been more frequent in ADPKD transplanted patients. In the present study, we investigated whether there is any association between PTDM and ADPKD in our patients. Methods: In this prospective study, 140 non-diabetic and nonsmoker successfully transplanted patients (27 ADPKD and 113 non ADPKD patients were enrolled during three years. Both groups were matched for age, sex, body mass index (BMI, duration of renal replacement therapy before transplantation and also immunosuppressive protocols after transplant. Post-transplant diabetes mellitus was defined as Clinical Practice Guidelines advocated by Canadian Diabetes Association. All patients were followed for 12 months. Results: PTDM occurred in 11.1% of ADPKD patients and in 13.1% of control group which was statistically insignificant (P > 0.05. The development of PTDM in ADPKD group was not related to sex, age, and hypertension, duration of renal replacement therapy before transplantation, BMI and serum creatinine levels (P > 0.05. Conclusion: Post-transplant diabetes mellitus appears not to be associated with autosomal-dominant polycystic kidney disease as an etiology of end stage renal disease.

    Full Text Available At present, the diagnosis of renal allograft rejection requires a renal biopsy. Clinical management of renal transplant patients would be improved if rapid, noninvasive and reliable biomarkers of rejection were available. This study is designed to determine whether such protein biomarkers can be found in renal-graft tissue proteomic approach. Orthotopic kidney transplantations were performed using Fisher (F344 or Lewis rats as donors and Lewis rats as recipients. Hence, there were two groups of renal transplant models: one is allograft (from F344 to Lewis rats; another is syngrafts (from Lewis to Lewis rats serving as control. Renal tissues were collected 3, 7 and 14 days after transplantation. As many as 18 samples were analyzed by 2-D Electrophoresis and mass spectrometry (MALDI-TOF-TOF-MS. Eleven differentially expressed proteins were identified between groups. In conclusion, proteomic technology can detect renal tissue proteins associated with acute renal allograft rejection. Identification of these proteins as diagnostic markers for rejection in patients′ urine or sera may be useful and non-invasive, and these proteins might serve as novel therapeutic targets that also help to improve the understanding of mechanism of renal rejection.

    Colchicine is the first-line treatment for familial Mediterranean fever (FMF), preventing both inflammatory attacks as well as the development of amyloidosis in the majority of the patients. However approximately 5-10% of patients are colchicine resistant/intolerant. Side effects of colchicine are more prominent in renal transplant recipients due to interaction with immunosuppressive drugs. Anti-interleukin (IL)-1 drugs (anakinra, canakinumab and rilonacept) have emerged as the most promising drugs in the treatment of colchicine-resistant and/or intolerant FMF. There are no existing reports in the literature on canakinumab use in renal transplant recipients with FMF. We report here the efficacy and safety of canakinumab in three renal transplant recipients who achieved a complete clinical response with elimination of attacks and normalization of serum C-reactive protein (CRP) levels without significant side effects. This highlights the advantage of use of this drug in this setting, which has a better tolerability compared to anakinra.

    2015-03-01

    Full Text Available The authors describe their first 10 cases of minimally invasive renal transplantation experience in the retroperitoneum with the aid of the da Vinci surgical system through a gas-less extra-peritoneal approach with a muscle sparing Gibson incision. The authors claim that they have utilized robotic arms for both vascular anastomosis and abdominal wall lifting which can be limiting in the obese patients. In recent years there is an increasing tendency for minimally invasive renal transplantation such as transperitoneal laparoscopic or robotic assisted renal transplantation. Those techniques still need modifications and search for a better technique is still in progress. In this study, mimicking the well-established open procedure with a smaller incision can be a better alternative, which requires confirmation in the future

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

    Etelcalcetide, a novel peptide agonist of the calcium-sensing receptor, prevents vascular calcification in a rat model of renal insufficiency with secondary hyperparathyroidism. Vascular calcification occurs frequently in patients with chronic kidney disease (CKD) and is a consequence of impaired mineral homeostasis and secondary hyperparathyroidism (SHPT). Etelcalcetide substantially lowers parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF23) levels in SHPT patients on hemodialysis. This study compared the effects of etelcalcetide and paricalcitol on vascular calcification in rats with adenine-induced CKD and SHPT. Uremia and SHPT were induced in male Wistar rats fed a diet supplemented with 0.75% adenine for 4 weeks. Rats were injected with vehicle, etelcalcetide, or paricalcitol for 4 weeks from the beginning of adenine diet. Rats fed an adenine-free diet were included as nonuremic controls. Similar reductions in plasma PTH and parathyroid chief cell proliferation were observed in both etelcalcetide- and paricalcitol-treated rats. Serum calcium and phosphorus were significantly lower in etelcalcetide-treated uremic rats and was unchanged in paricalcitol-treated rats. Both serum FGF23 and aortic calcium content were significantly lower in etelcalcetide-treated uremic rats compared with either vehicle- or paricalcitol-treated uremic rats. The degree of aortic calcium content for etelcalcetide-treated rats was similar to that in nonuremic controls and corroborated findings of lack of histologic aortic mineralization in those groups. In conclusion, etelcalcetide and paricalcitol similarly attenuated progression of SHPT in an adenine rat model of CKD. However, etelcalcetide differentially prevented vascular calcification, at least in part, due to reductions in serum FGF23, calcium, and phosphorus levels.

Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

    2015-07-01

    Full Text Available In renal transplantation surgery, double J stents (DJS are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmantation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery.

    1991-01-01

    The aim of this study is to analyse whether or not old age alone significantly affects the outcome of patient and graft survival in cadaveric renal transplantation, and thus whether it should be a selection criterion for induction into transplant programmes, given the current shortfall in donor organs in the United Kingdom. Data is presented on all 307 solitary cadaveric renal allografts performed at Addenbrooke's Hospital, Cambridge between January 1983 and December 1987. Patients are divided into those aged less than 60 years (n = 243) and those aged 60 years and over (n = 45) at the time of transplantation. There is no significant difference in graft survival between the two groups (60.3% and 62.2%) at 18-60 months (mean 42 months) post-transplantation. Patient survival in the two groups is significantly different (83% and 64.4%, P less than 0.01) at the same point. Causes of graft loss, death, and end-stage renal failure are analysed. It is suggested that patients aged 60 years and over may require less immunosuppression but that graft loss from rejection in this group has a high associated mortality. We conclude that cadaveric renal transplantation in the elderly should only be undertaken after careful selection, paying particular attention to evidence of cardiovascular disease and full counselling of the risk of death with these patients.

    We report a case of a 41-year-old man suffering from paranoid schizophrenia. The patient has been consulting in our psychiatric hospital since he was 29 years old. Eight years later, he developed kidney failure and required peritoneal dialysis. After more than two years, the nephrology team indicated a renal transplantation and his brother suggested giving his kidney. There were no obstacles for transplantation in the immune and histological compatibilities; the psychiatric staff decided to check the patient's compliance with medication. The patient was compliant to all his medications and to the salt-free diet after the transplant operation. Few weeks later, he developed steroid-induced diabetes. Through the last two years, he had psychotic exacerbations with major anxiety and fear of losing the transplant. These relapses were managed by increasing doses of antipsychotics without need for hospitalization. At the present time, three years after transplantation, the nephrologists are decreasing the immunosuppressive agents and the steroids. The renal function is optimum and the diabetes is stabilized. This case exemplifies the potential for schizophrenic patients to undergo renal transplantation and to comply with follow-up medical care through a close cooperation between the patient's family, the psychiatric staff and the nephrology team.

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

  10. Calciphylaxis after renal transplant. Three clinical cases report

    Full Text Available Introduction: Calciphylaxis (CFX is a syndrome characterized by deposition of calcium in the intima and media of vessels, intimal proliferation, fibrosis, luminal thrombosis, tissue ischemia and necrosis. Its initial report and subsequent descriptions were associated with chronic renal failure. There is little information regarding the possible effect of the recovery of renal function secondary to kidney transplantation in the incidence of this disease. Methods: Center retrospective study. We analyze in this report the three cases of patients who developed CFX after a renal transplant within a cohort of 448 kidney and kidney-pancreas transplant patients from January 1th 2001 to January 1th 2014 in our Hospital. Results: Three patients were found to have CFX. All of them had hypercalcemia (serum calcium average 11.5 mg/dl at first year post transplant and 2 patients at diagnosis of CFX. PTHi in the three CFX patients was 2 pg/ml, 62,3pg/ml and 3561pg/ml respectively. Hypoalbuminemia was found in all patients. Two patients were diabetic. Only one patient was obese and under anticoagulation treatment. In all cases a biopsy provided the diagnosis of certainty for calciphylaxis. Median serum creatinine at diagnosis was 1.5 mg/dl (1.2 mg/dl 1.2 mg/dl and 2 mg/dl, respectively and the average time between transplantation and calciphylaxis diagnosis was 32 months. In all cases, strict control of phosphorus and hypercalcemia and sodium IV thiosulfate treatment was performed. The evolution was successful in two patients, controlling blood calcium and improving cutaneous manifestations with preservation of renal function. Conclusions: CFX prevalence in a cohort of 448 kidney and kidney-pancreas transplant patients from 2001 to 2014 was 0.66%, less than reported in dialysis patients. Factors associated with CFX in our patients were hypercalcemia in the first year after renal transplant and at the time of the event, hypoalbuminemia, diabetes and disorders

    Hyperphosphatemia in renal failure has been identified as a major role in the pathogenesis of hyperparathyroidism that is independent of changes in serum calcium and 1,25(OH)(2)D(3). The aim of this study was to evaluate the expression of parathyroid Pit-1 in hyperphosphatemia-induced secondary hyperparathyroidism (SHPT) of chronic renal failure (CRF) rats. Wistar rats with CRF induced by 5/6 nephrectomy were ramdomly fed with diet containing 1.2% inorganic phosphate (Pi, high phosphate (HP) group, n = 9) or 0.2% Pi (low phosphate (LP) group, n = 9) for 10 weeks starting from the fourth week after the surgery. Another 7 nephrectomy rats with HP diet were intraperitoneally injected with phosphonoformic acid (PFA, the specific inhibitor of Pit-1, HP + PFA group) 0.15 g/kg every other day for 10 weeks starting from HP diet. Another 6 HP rats injected with the same amount of normal saline as the control of the HP + PFA group (HP + saline group). At the same time, 9 rats with sham surgery received HP diet as the controls. At the 4th week and 14th week, blood was taken for measurement of serum creatinine (SCr), serum calcium (SCa), serum phosphorus (SPi), 1,25(OH)(2)D(3) and intact parathyroid hormone (iPTH). At the 14th week, two parathroid glands (PTGs) of each rat were removed by microsurgery, one gland for immunohistochemistry analysis of proliferating cell nuclear antigen (PCNA), the other one for detection of Pit-1 by Western blotting, and for the measurement of Pit-1 mRNA and PTH mRNA by real-time quantitative polymerase chain reaction. In nephrectomy rats, high dierary phosphate induced a marked increase in serum phosphate, iPTH, PTH mRNA and PCNA parathyroid cells, accompanying Pit-1 and its mRNA in parathyroid gland increased significantly. However, serum Ca and 1,25(OH)(2)D(3) remained unchanged. PFA decreased Pit-1 and its mRNA levels to reduce intact PTH, PTH mRNA and PCNA-positive parathyroid cells.

    Serial Tc-99m DTPA studies were performed to evaluate renal transplant blood flow and function in a 34-year-old woman. A hypervascular pelvic mass with increased blood pool activity was intermittently identified. This hypervascular lesion suggested a pathologic condition of the pelvis, and its blood pool simulated bladder activity, confusing interpretation of renal function. This perplexing vascular lesion was the uterus, with varying degrees of blood flow and blood pool activity depending on the timing of the renal study in relation to the menstrual cycle.

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

  16. Renal Vein Reconstruction for Harvesting Injury in Kidney Transplantation

    Full Text Available Kidney transplantation is the best treatment choice in the end-stage renal disease. In the renal transplantation, renal vein damage or shortness which occurs during cadaveric or living donor nephrectomy causes technical difficulties for surgeons. The lack of the donors already especially cadaveric, the acquirement of the graft, gets very much importance. In this report, it is aimed to share the clinical experiment by which it seen, how anastomosis can become appropriate by using the renal vein which is damaged in the way that anastomosis cannot be done anyway by using cadaveric vena cava graft. The renal vein brought to length for anostomosis which is repaired by using cadaveric vena cava graft, is anastomosed successfully by becoming an end-to-side of the external iliac vein of the recipient. Vascular anastomoses are applied easily in technique. The time of the warm ischemia was under 2 hours and the kidney was functional in the post-operative period. Renal vein trombosis was not observed. The renal vein damage occured during cadaveric or living donor nephrectomy, can be repaired by some methods. In the kidneys in which vein requirement is done, the success rates are rather high although acute tubular necrosis and delayed function can be seen more.

    2017-10-06

    Primary hyperparathyroidism (PHPT) is a common endocrinological process, characterized by chronic elevation of serum concentrations of calcium and parathyroid hormone (PTH). Many years ago, the most frequent forms of clinical presentation were symptomatic renal or skeletal disease with moderate or severe hypercalcemia; however, currently, most patients have few symptoms and mild hypercalcemia. A new form of presentation called normocalcemic PHPT has also been described but clinical consequences are not well established. The biochemical profile of PHPT is characterized by hypercalcemia and high or inappropriately normal PTH concentrations. Parathyroidectomy is the only definitive cure. Medical treatment with the calcimimetic cinacalcet has been shown to normalize calcemia in a high percentage of cases. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Our experience with renal transplantation in children with inferior vena cava thrombosis is presented in this study. Of the 238 children who have received renal transplants at our institution, four had IVC thrombosis (discovered during pretransplant evaluation: three patients; found at surgery: one patient). The pretransplant US evaluation diagnosis of IVC thrombosis in three patients was confirmed by transjugular retrograde cavography. There were no signs of hypercoagulability or IVC thrombosis symptoms prior to diagnosis in any patient. The graft was implanted in a left orthotopic position in three patients. Venous drainage was attained to the infrahepatic vena cava or native renal vein after ipsilateral nephrectomy. The renal artery of the graft was anastomosed to the aorta. In one patient, the graft was placed in the left iliac fossa. Patient and graft survival are 100%. Three grafts are functioning normally after a mean follow-up of 3.7 yr. The graft placed in the iliac fossa has moderate dysfunction due to high pressure venous outflow. Children with IVC thrombosis can be successfully transplanted orthotopically. Candidates with any suspicious-looking occlusion on ultrasound should be studied by retrograde venography to confirm diagnosis prior to transplantation.

    2004-01-01

    Full Text Available OBJECTIVE: To determine the incidence of lymphocele in the follow-up of patients who underwent renal transplantation, as well as potential factors responsible or associated to its development. MATERIALS AND METHODS: All records from patients who were treated for lymphocele in our institution between May 1989 and December 2002 were reviewed, as well as their clinical outcome following treatment. RESULTS: Among 450 patients who underwent renal transplantation in the period, only 3 required treatment, with 2 of them treated due to the collection volume, and the other due to symptoms (pain, representing an incidence of only 0.6%. COMMENTS: The occurrence of perirenal fluid collections following renal transplantation is frequent. In cases where treatment is required, this can generate an excessive morbidity for the patient, which motivates the development of preventive methods, such as minimally invasive therapy, for such cases. CONCLUSION: Careful ligation of lymphatic vessels both during graft preparation and during its implantation, added to post-operative drainage can significantly contribute to reducing the incidence of lymphocele following renal transplantation.

    Full Text Available Abstract Background The use of grafts with multiple renal arteries has been considered a relative contraindication because of the increased incidence of vascular and urologic complications The aim of this study is to determine whether the kidney grafts with multiple arteries have any adverse effect upon post-transplant graft and patient survival. Methods We reviewed the records of 225 adult kidney transplants done consecutively at our institution. Twenty-nine patients (12.8% had grafts with multiple renal arteries. We analyzed the incidence of post-transplant hypertension and vascular complications, mean creatinine levels, patient and graft survival. In 17 cases reconstruction was done as conjoined anastomosis between two arteries of equal size, and in 6 cases as end-to-side anastomosis of smaller arteries to larger arteries. Multiple anastomoses were performed in 6 cases. Results In one patient postoperative bleeding occurred. Mean systolic blood pressures, creatinine levels at first year and last follow-up and complication rates were all in acceptable ranges. There was no significant difference in graft and patient survival between multiple and single renal artery allografts. Conclusion Although the kidney grafts with multiple renal arteries have been considered a relative contraindication because of the increased risk of complications, in our study allografts with multiple arteries were used successfully in kidney transplantation.

    The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft. © 2011 International Society of Nephrology

    Immunosuppressive regimens in renal transplantation frequently contain corticosteroids, but many centers withdraw steroids as a consequence of unwanted side effects of steroids. The optimal timing to withdraw steroids after transplantation, however, remains unclear. The aim of this study was to determine an optimal time point following kidney transplantation that is associated with reduced mortality without jeopardizing the allograft to allow safe discontinuation of steroids. We conducted a retrospective cohort study and computed a concatenated landmark-stratified Cox supermodel to estimate hazard ratios and 95% confidence intervals for mortality and graft loss using dynamic propensity score matching to adjust for confounding by indication. A total of 6070 first kidney transplant recipients in the Austrian Dialysis and Transplant Registry who were transplanted between 1990 and 2012 were evaluated and classified according to steroid treatment status throughout follow-up after kidney transplantation; 2142 patients were withdrawn from steroids during the study period. Overall, 1131 patients lost their graft and 821 patients in the study cohort died. Steroid withdrawal within 18 months after transplantation was associated with an increased rate of graft loss compared to steroid maintenance during that time (6 months after transplantation: HR = 1.8; 95% CI, 1.3 to 2.6; 18 months after transplantation: HR = 1.3; 95% CI, 1.1 to 1.6; 24 months after transplantation: HR = 1.2; 95% CI, 0.9 to 1.5), while mortality was not different between groups. Our findings suggest that steroid withdrawal after anti-IL-2 induction in the first 18 months after transplantation is associated with an increased risk of allograft loss.

    1993-06-01

    Renal transplantation is considered now the definitive treatment for patients with end-stage renal disease (ESRD). Unfortunately, the worldwide shortage of kidneys remains the most important obstacle to transplantation. In developing countries, including those of the Middle East, the shortage is even more dramatic. Despite great efforts to establish and maintain successful transplant centers, the number of kidneys that have been transplanted in the last few years has actually declined. The lack of a dependable kidney source played well into the hands of unscrupulous entrepreneurs who started brokerage of organs for profit. In this practice, patients with ESRD travel to India and other countries to purchase kidneys from living genetically non-related poor donors. Patient care was therefore relegated to the laws of the marketplace and both patients and donors were exploited to maximize profit. Additionally, reported results of this type of transplantation were inferior to those of other types of transplantation. Not unexpectedly, these issues have created intense controversy among transplant physicians and the general public in which moral, ethical and medical issues were debated. To investigate these issues, we conducted a large multicenter study in Saudi Arabia, Bahrain and Egypt. In the first phase of this study, we surveyed 50 institutions regarding their attitude toward LNRRT, of which 22 responded. The results of our survey clearly show that patients with ESRD take the initiative in seeking LNRRT despite physician discouragement and significant financial burden.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Bartter syndrome (BS is a clinically and genetically heterogeneous inherited renal tube disorder characterized by renal salt wasting, hypokalemic metabolic alkalosis and normotensive hyperreninemic hyperaldosteronism. There have been several case reports of BS complicated by focal segmental glomerulosclerosis (FSGS. Here, we have reported the case of a BS patient who developed FSGS and subsequent end-stage renal disease (ESRD and provided a brief literature review. The patient presented with classic BS at 3 months of age and developed proteinuria at 7 years. Renal biopsy performed at 11 years of age revealed a FSGS perihilar variant. Hemodialysis was initiated at 11 years of age, and kidney transplantation was performed at 16 years of age. The post-transplantation course has been uneventful for more than 3 years with complete disappearance of BS without the recurrence of FSGS. Genetic study revealed a homozygous p.Trp(TGG610Stop(TGA mutation in the CLCNKB gene. In summary, BS may be complicated by secondary FSGS due to the adaptive response to chronic salt-losing nephropathy, and FSGS may progress to ESRD in some patients. Renal transplantation in patients with BS and ESRD results in complete remission of BS.

    Recent studies demonstrate that the human microbiota, the collection of microorganisms growing on and in individuals, have numerous bidirectional interactions with the host, influencing immunity, resistance to infection, inflammation and metabolism. Little has been done to study the potential associations between microbiota composition and transplant outcome. Here, we investigated the longitudinal changes in the blood, urinary, oral and rectal microbiota of renal allograft recipients before and at 1 and 6 months after transplantation. The results showed major changes in microbiota composition as a result of the transplant episode and associated medications, and these changes persisted over time. The high interindividual variation as well as differences in response to transplantation suggested that it is unlikely that the same specific microbiota members can serve as universal diagnostic markers. Rather, longitudinal changes in each individual's microbiota have the potential to be indicative of health or disease. Use of sensitive nucleic acid-based testing showed that urine, irrespective of disease states, more often harbors a diverse microbiota than appreciated by conventional culture techniques. These results lay the groundwork to construct more comprehensive future investigations to identify microbiota characteristics that can serve as diagnostic markers for transplant health and to guide intervention strategies to improve transplant outcome. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

Sixty chronic renal failure patients with SPHT scheduled for subtotal parathyroidectomy were randomized to receive general anesthesia (group GA), general anesthesia plus bilateral superficial and deep cervical plexus block (group BD), or general anesthesia plus bilateral superficial cervical plexus block (group BS) (n = 20). Bilateral superficial cervical plexus block or combined superficial and deep cervical plexus block with 0.5% ropivacaine was administered. Postoperative pain was assessed using visual analogue scale (VAS). VAS score at 1 hour, 4 hours, and 8 hours after operation was 3.71 ± 0.60, 2.72 ± 0.54, 2.17 ± 0.75 in BS group; 4.00 ± 0.28, 2.89 ± 0.21, and 2.46 ± 1.01 in BD group, significantly lower than in GA group (6.50 ± 0.50, 5.02 ± 0.54, and 4.86 ± 0.51, respectively). The dosage of tramadol was 109.0 ± 35.2 mg in BS group and 93.0 ± 24.52 mg in BD group, significantly lower than in GA group (300.0 ± 27.13 mg). The incidence of complications in GA group (90%) was significantly higher than in BS group (30%) and BD group (15%). Serum glucose and norepinephrine levels were significantly higher at 1 hour, 4 hours, and 8 hours after operation, but returned to baseline levels at 24 hours after operation. Superficial cervical plexus block or combined superficial and deep cervical plexus block effectively reduces postoperative pain, stress response, and complications in SHPT patients who undergo subtotal parathyroidectomy.

    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 Kidney transplant recipients frequently suffer from skin infections and malignancies, possibly due to the effects of long-term immunosuppressive therapy. While the relationships between immunosuppression and these pathological conditions have been widely investigated, little is known about the relative incidence and characteristics of inflammatory skin diseases in this type of patient. In this study, we analyze the incidence of a number of inflammatory cutaneous diseases in a cohort of patients who underwent kidney transplantation. Although our study shows a relatively low incidence of these pathologies in transplanted patients—in agreement with the general action of immunosuppressant therapies in reducing inflammation—we scored a different efficacy of the various immunosuppressive regimens on inflammatory and autoimmune skin diseases. This information can be key for designing immunosuppressive regimens and devising accurate follow-up protocols.

    We report a case of an adolescent boy with Down's syndrome and ESRD on hemodialysis who developed mild Graves' disease that was not amenable to radioablation, surgery, or ATDs. After 14 months of observation without resolution of Graves' disease, he successfully received a DDRT with a steroid minimization protocol. Thymoglobulin and a three-day course of steroids were used for induction and he was started on tacrolimus, MMF, and pravastatin for maintenance transplant immunosuppression. One month after transplantation, all biochemical markers and antibody profiling for Graves' disease had resolved and remain normal one yr later. © 2016 John Wiley & Sons A/S.

    It is unclear whether patients with heart failure and renal insufficiency should receive a simultaneous heart and kidney transplant or whether a single heart transplantation is sufficient to restore native renal function. We analyzed the renal plasma flow and glomerular filtration of the native and transplant kidneys in eight patients long term after simultaneous heart and kidney transplantation using a dynamic MAG3 radioisotope scan and serum creatinine determinations. All subjects had been hemodialysis dependent before transplantation. Seven patients suffered from an intrinsic renal disease that were diabetic nephropathy in three cases, small fibrotic kidneys of undetermined origin in two cases, one lupus nephritis, and cyclosporine nephrotoxicity in one patient who had a previous heart transplant. In one patient renal insufficiency was considered to be solely due to renal hypoperfusion because no intrinsic renal disease could be detected. All patients were on cyclosporine-based triple immunosuppression, transplanted for 4 to 10 years, exhibited cardiac ejection fractions of more than 50% and had normal serum creatinine values. Radioisotopic scan showed no function of the native kidneys in all seven patients with intrinsic renal disease but exhibited normal function of the native kidneys as well as the renal transplant in the patient without intrinsic kidney disease before transplantation. These data suggest that a simultaneous heart and kidney transplantation is necessary in patients with cardiomyopathy and renal insufficiency due to primary kidney disease, but not in those with hemodynamically mediated renal failure, even if an immunosuppressive regimen with calcineurin inhibitors is used.

    To study the anatomy characters of renal artery and the treatment of multiple arteries in living donor renal grafts. Records of 142 living donors were analyzed in our center. We analyzed the anatomic structure of renal arteries by DSA and CTA pre-transplantation. Thirty-one kidneys with multiple arteries were transplanted after reconstruction. Then clinical effects were compared between multiple-renal-arteries group (n=31) and single-renal-artery group (n=111). The incidence of multiple renal artery was 30.99%, and there was no difference between both sides (left kidney 22.54%, right kidney 22.13%). If the multiple artery occurred in left or right kidney, the incidence of the multiple artery occurred in the other side was 56.25% and 60.00%, respectively. The diameter of left main renal artery was more magnanimous (P=0.001) and the first branch was more closed to abdominal aorta (P=0.004). Operation time and warm/cool ischemia time were longer in the multiple-renal-arteries group. However, estimated blood loss, delayed graft function, acute rejection and flow rate of arcuate artery were similar in both groups, the same as serum creatinine and serum creatinine clearance rate on day 7, 1 month and 3 month post-operation. It was shown by repeated measures ANOVA that graft with multiple arteries didn't affect the tendency of renal function at early time post-operation. Comprehending the character of renal artery and accurate treatment of multiple artery anastomosis are critical for the effect of the living kidney transplantation.

    A 38-year-old woman with end stage renal disease received a living related donor-renal transplant to the right iliac fossa. She developed anuria a week later. Tc-99m MAG{sub 3} renal scintigraphy demonstrated no perfusion, uptake, or excretion of the radioactive tracer from the renal transplant. The expected area of the renal allograft appeared as a photopenic area with increased rim activity. The gallbladder and bowel activities were observed on delayed images at 24 hours. There was no blood flow within the renal artery on renal doppler examination. This case shows total absence of perfusion and function in the infarcted renal transplant with extrarenal excretion of Tc-99m MAG{sub 3} caused by acute renal artery thrombosis.

    We have previously noted marked acceleration in the proliferative activity of parathyroid cells in rats with spontaneous hypercholesterolemia and secondary hyperparathyroidism. Using this proliferative potential we investigated whether transplantation of these enlarged parathyroids into normal rats would induce hyperparathyroidism and renal stones. We used 26-week-old male rats with spontaneous hypercholesterolemia as donors, and 5-week-old normal male Sprague-Dawley rats and rats with spontaneous hypercholesterolemia as recipients. Enlarged parathyroid glands were transplanted into group 1--Sprague-Dawley rats with no treatment, group 2--Sprague-Dawley rats that received FK-506 as an immuno-suppressor, group 3--rats with spontaneous hypercholesterolemia rats that underwent parathyroidectomy plus FK-506 administration and group 4--Sprague-Dawley rats that underwent parathyroidectomy plus FK-506 administration. Parathyroidectomy was performed in recipients before transplantation to ensure a low calcium condition. Grafts were rejected within 11 and 15 weeks in groups 1 and 2, respectively. In group 3, 78% of the grafts were successful even after 19 weeks. In group 4 graft survival was 30% at 15 weeks with complete rejection at 19 weeks. In group 3 gradually elevated serum parathyroid hormone was observed as well as stone plaques containing calcium oxalate and calcium phosphate in renal tubules located mainly in the corticomedullary junction. An increased number of plaques was associated with higher parathyroid hormone. Our study shows that transplanted parathyroid glands function with an immunosuppressive agent and the maintenance of hypocalcemic conditions, and they secrete sufficient parathyroid hormone to demonstrate hyperparathyroidism. Plaque in these kidneys indicates an early stage of urolithiasis caused by hyperparathyroidism.

    PSV of renal transplant vessels, calculated during allograft ultrasonography, has previously been shown to correlate with TRAS. Controversy exists regarding the threshold PSV value (adult range: 1.5-3.0 ms), which should prompt further, more invasive investigations to confirm the diagnosis of TRAS. Furthermore, there is a paucity of literature regarding PSV values in the pediatric renal transplant population. In a group of pediatric renal transplant patients, we correlated post-operative renal transplant PSV values with BP, renal function (serum creatinine) and TRAS. All patients who underwent cadaveric or living-related renal transplantation at the HSC between 2001 and 2004 with at least 6 months of follow-up were reviewed through the HSC multi-organ transplant database. Post-operative allograft Doppler ultrasonography was performed during routine follow-up. PSV values obtained were correlated with BP and serum creatinine performed concomitantly. Finally, we correlated PSV in those patients who underwent more intensive investigations, including magnetic resonance and conventional angiography. Fifty-three patients underwent transplantation during the study period. Complete data available for 50/53 demonstrated a mean PSV of 2.13 m/s (range: 0.9-6.1 m/s) for all patients. Of six patients who underwent MRA for suspicion of TRAS, two (with mean PSV values of 1.93 m/s) were found to have clinically significant stenoses. Four of six without angiographic evidence of TRAS had mean PSV values of 2.22 m/s. Patients suspected of having TRAS demonstrated elevated median serum creatinine values compared with those without clinical suspicion of TRAS. However, both mean PSV and BP were not found to be statistically different in both patient subgroups. Furthermore, there was no correlation identified between PSV and serum creatinine and BP in these patient populations. Despite the utility of PSV for monitoring adult renal transplant patients, we did not find that PSV correlated

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

    Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system. Coronary angiographies conducted between March 2008 and April 2013 from 99 candidates for renal transplantation from two transplant centers in São Paulo state were analyzed for associations between significant coronary artery diseases (≥70% stenosis in one or more epicardial coronary arteries or ≥50% in the left main coronary artery) and clinical parameters. Univariate logistic regression analysis identified diabetes, angina, and/or previous infarction, clinical peripheral arterial disease and dyslipidemia as predictors of coronary artery disease. Multiple logistic regression analysis identified only diabetes and angina and/or previous infarction as independent predictors. The results corroborate previous studies demonstrating the importance of these factors when selecting patients for coronary angiography in clinical pretransplant evaluation.

    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.

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

    Full Text Available The purpose of review was increasing number of opportunistic infections with use of newer immunosuppression and difficulty in diagnosis and management of such patients. For this review, MEDLINE database was searched from 2000 to 2006 with the keywords of opportunistic infections in renal transplantation. Opportunistic infection is a serious clinical complication in patients receiving immunosuppressive therapy after kidney transplantation. The two major factors for successful renal transplantation are better control of rejection and better prevention and treatment of infection. In renal allograft recipient, immunosuppressive drug therapy is the major cause of immunocompromised status and occurrence of infections, which arise most commonly as a result of invasion by endogenous opportunists. The opportunistic infections with varicella zoster viruses, parvovirus B-19, polyomavirus, nocardia and mucormycosis in immunosuppressed patients were present with severe complications that are reviewed in this article. As a result of use of strong immunosuppressive drugs like tacrolimus, mycophenolate mofetyl (MMF and antirejection therapy with antithymocyte globulins (ATG, these infections are now seen frequently, so they should always be included in differential diagnostic consideration. New diagnostic procedures and new treatment strategies are required to allow early detection and successful treatment of opportunistic infections in kidney transplant recipients.

    Ocular complications after renal transplantation are common in adults. Nevertheless, data regarding these complications in children are insufficient. The purpose of the present study was to assess ocular morbidity in pediatric renal graft recipients. A retrospective observational study of 71 patients aged 11.2 +/- 5.5 yr was conducted. Mean duration of follow-up was 5.6 +/- 3.5 yr. A total of 16 ocular complications were found in 12 (17%) of the patients. Three patients suffered from more than one complication. Cataract was the most common finding (six patients, 8.4%) followed by swollen disk and hypertensive retinopathy in four patients (5.7%) each and increased intra-ocular pressure in two patients (3%). Mean time interval between transplantation and occurrence of first abnormal ocular finding was 37 +/- 34.5 months. The follow-up time was significantly longer in patients with ophthalmological problems than in those without complications (7.8 yr vs. 5.2 yr, p < 0.02). No statistically significant association was found between the occurrence of ocular complications and the age of the patients at transplantation, donor source, duration of dialysis prior to transplantation, previous corticosteroid therapy or presence of acute rejection episodes. The results of the study point to the importance of regular concurrent ophthalmological follow-up in pediatric renal graft recipients to reduce/prevent ocular morbidity.

    Full Text Available This study compares outcomes and graft function of right and left grafts of deceased donor. We studied 120 kidney recipients from 60 deceased donors in Shiraz organ transplantation center from 1988 to 2004. We analyzed data regarding age, gender, side of grafts, duration of pre-transplant dialysis, hospital stay, serial creatinine levels, cold ischemic time, complications, graft function, patient survival rates, and post-operative complications. Recipients were divided into two groups: group 1 consisted of 60 recipients who received right renal graft (43 males, 17 females; mean age: 33.6 ± 7.3 years, and group 2 consisted of 60 recipients who received left renal graft (45 males, 15 females; mean age: 29.2 ± 6.4 years. No statistically significant differences were found in duration of pre-transplant dialysis, cold ischemic time, acute rejection rates, post-operative surgical and vascular complications′ rates, hospital stay, renal function, and one year graft survival rates. We conclude that although it is advised to use left kidney from live donors because of longer vessel length, easier surgical technique and organ handling, and shorter ischemic time, we got the same outcome in left and right deceased renal grafts.

    Mounting pressures to resolve multiple challenges related to quality, cost, and access in a resource-driven, customer-focused health care environment have compelled clinicians to develop innovative strategies to provide cost-effective, state-of-the-art care. Targeted patient groups include those associated with high cost, high volume, or high resource use. Patients undergoing renal transplantation fall into one or more of these categories. Recently, the management of patients with end-stage renal disease (ESRD) has come under national focus, as evidenced by the fact that Health Care Financing Administration (HCFA) has commissioned an ESRD managed care demonstration project. The purpose of this article is to describe how one case management tool--the clinical pathway--can be used to decrease costs and improve outcomes associated with renal transplantation. This discussion will include a review of the origins and components of clinical pathways and a description of how one institution developed, implemented, evaluated, and refined a renal transplantation clinical pathway.

The current kidney waiting list in the US contains more than 100,000 patients. This need has led to the inclusion of older donors with worsening renal function, as well as greater utilization of kidneys from non-heartbeating (donation after cardiac death donors. Coinciding with this trend has been a growing interest in technology to improve the function of these more marginal organs, the most important of which currently is machine perfusion (MP of donated kidneys after procurement. While this technology has no standard guidelines currently for comprehensive use, there are many studies that demonstrate higher organ yield and function after a period of MP. Particularly with the older donor and during donation after cardiac death cases, MP may offer some significant benefits. This manuscript reviews all of the current literature regarding MP and its role in renal transplantation. We will discuss both the experience in Europe and the US using machine perfusion for donated kidneys.Keywords: machine perfusion, renal transplantation, kidney pumping, renal failure, organ donation

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

    Surgical difficulties of renal transplantation related to prostate cancer (PC) treatment and the results of renal transplantation after radical prostatectomy are currently poorly known, as well as oncological follow-up before and after renal transplantation. We performed a retrospective study including all patients diagnosed with PC before renal transplantation in our department. Nineteen patients were included between August 2003 and December 2013. The mean age at diagnosis of PC was 61.7 years (range 51.4-71.1). PSA mean level at diagnosis was 8.5 ng/ml (range 4.8-20). Fourteen had a retro-pubic and 5 a laparoscopic prostatectomy. Three patients underwent radiotherapy for positive surgical margins or extra-capsular extension. Fourteen patients were transplanted. The mean time lapse between prostatectomy and kidney transplantation was 32.8 months (range 14-71). Seven recipients (50%) were transplanted less than 24 months after prostatectomy. Post-transplantation surgical complications were not significantly related to dissection difficulties (p=0.2). No recurrence of PC was observed after renal transplantation, with a mean follow-up of 38 months (range 6-77.9). Prostate cancer discovered before renal transplantation should be treated by radical prostatectomy to assess recurrence risk. If the PC is at low risk of recurrence, it seems possible to shorten the 2-year period of oncologic follow-up before transplantation called for in current recommendations.

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

    Full Text Available Spontaneous clearance of hepatitis C virus (HCV is rare in immunocompromised patients, such as those who have undergone organ transplantation. It has been recognized that patients receiving liver transplantation for HCV-related disease have decreased graft and patient survival compared with those transplanted for other etiologies. There is a growing trend toward treating HCV recurrence aggressively after liver transplantation. For other organ transplant recipients with concurrent HCV, treatment is not often an option, given the high rates of graft rejection and loss secondary to interferon and its immunomodulatory effects. Although spontaneous clearance of HCV has been reported in recipients of solitary liver and renal transplants, a common factor arising in these cases has been previous exposure to interferon. To date, no reports of spontaneous clearance of HCV RNA have been reported in a multiorgan transplant recipient. A case of spontaneous clearance of HCV RNA in an immunocompromised patient, within five months of simultaneous liver and kidney retransplantation is described. Importantly, this patient had no previous exposure to interferon.

  20. Histology and proteinuria after renal transplantation.

    Proteinuria is a nonspecific sign of the troubled renal allograft. Small increases of proteinuria more than 150 mg/d are associated with poor renal allograft survival. During the 90s, it was assumed that chronic allograft nephropathy, defined as the presence of interstitial fibrosis and tubular atrophy, was the histologic lesion responsible for proteinuria and renal function deterioration in most kidneys. Thus, the interest to pursue a histologic diagnosis in patients with proteinuria or renal function deterioration faded during this period. In 2005, the criteria to diagnose chronic humoral rejection, a condition that in the previous year was not distinguished from chronic allograft nephropathy (CAN), were defined. The description of chronic humoral rejection as a major cause of proteinuria and graft loss represented a change of paradigm because it became clear that chronic humoral rejection and other conditions such as recurrence of original disease, de novo glomerulonephritis, polyomavirus infection, and others are responsible for proteinuria. These conditions can be diagnosed on histologic and clinical grounds, provided that special techniques such as C4d, immunofluorescence, immunohistochemistry, electron microscopy, and determination of donor specific antibodies are used. Thus, it became rather clear that proteinuria should be studied by means of a renal biopsy, especially if we take into consideration that there is very poor correlation between the amount of proteinuria and the disease responsible for it. Studies based on surveillance biopsies showed that histologic diagnosis precedes clinical manifestations. Despite the lack of clinical trials, series of patients have shown that different entities respond to different treatments, further reinforcing the idea that early diagnosis and early treatment may contribute to improve graft outcome.

    2016-02-01

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

    To compare the usefulness of Doppler ultrasonography and renal scintigraphy in the assessment of short- and long-term function of transplanted kidneys. We retrospectively reviewed the cases of 79 patients who underwent Doppler ultrasonography and technetium-99m diethylene triamine pentaacetic acid renal scintigraphy on the same day, within 4 days of renal transplantation. Image parameters were evaluated for statistical differences. There was a strong positive correlation between the glomerular filtration rate (GFR) as measured by renal scintigraphy and the estimated GFR (eGFR) based on serum creatinine levels (correlation coefficient = 0.71). Scan grade according to the time-activity curve, resistive index, and end diastolic velocity showed moderate correlations with the eGFR (correlation coefficients = -0.557, -0.329, and 0.370, respectively) in the early post-transplantation period. The mean survival time was longer in patients with lower resistive indices (≤ 0.68, 54.9 months vs. > 0.68, 29.5 months) and lower pulsatility indices (≤ 1.32, 53.8 months vs. > 1.32, 28.7 months); however, there were no statistically significant differences in the long-term follow-up period (p = 0.121 for resistive index and p = 0.074 for pulsatility index). Renal scintigraphy is a more sensitive method than Doppler ultrasonography for assessing transplanted kidney function in the early post-transplantation period. Doppler ultrasonography might reflect the long-term survival time. However, it is difficult to predict long-term renal function using either method.

    Changes in mineral metabolism and bone structure develop early in the course of chronic kidney disease and at end-stage are associated with increased risk of fragility fractures. The disruption of phosphorus homeostasis leads to secondary hyperparathyroidism, a common complication of chronic kidney disease. However, the molecular pathways by which high phosphorus influences bone metabolism in the early stages of the disease are not completely understood. We investigated the effects of a high phosphorus diet on bone and mineral metabolism using a 5/6 nephrectomy model of chronic kidney disease. Four-week old rats were randomly assigned into groups: 1) Control with standard diet, 2) Nephrectomy with standard rodent diet, and 3) Nephrectomy with high phosphorus diet. Rats underwent in vivo imaging at baseline, day 14, and day 28, followed by ex vivo imaging. Cortical bone density at the femoral mid-diaphysis was reduced in nephrectomy-control and nephrectomy-high phosphorus compared to control rats. In contrast, trabecular bone mass was reduced at both the lumbar vertebrae and the femoral secondary spongiosa in nephrectomy-high phosphorus but not in nephrectomy-control. Reduced trabecular bone volume adjusted for tissue volume was caused by changes in trabecular number and separation at day 35. Histomorphometry revealed increased bone resorption in tibial secondary spongiosa in nephrectomy-control. High phosphorus diet-induced changes in bone microstructure were accompanied by increased serum parathyroid hormone and fibroblast growth factor 23 levels. Our study demonstrates that changes in mineral metabolism and hormonal dysfunction contribute to trabecular and cortical bone changes in this model of early chronic kidney disease.

    Renal artery anastomosis peak systolic velocity (RAA PSV) exceeding 250 cm/s and a ratio of the renal artery to the adjacent external iliac artery (RAA:EIA) exceeding 1.8 historically suggest significant transplant renal artery stenosis (TRAS). However, the range of RAA PSV in transplants without TRAS has not been established. A retrospective review of renal transplants at a single institution over 5 years was performed identifying patients without graft dysfunction, failure, or refractory hypertension. RAA PSV obtained during interval postoperative sonograms was recorded. Of 1141 patients, 844 met the inclusion criteria. Mean RAA PSV for 377 patients evaluated within 2 days of transplant measured 195 cm/s; RAA PSV exceeded 250 cm/s in 97 patients (26%). Mean RAA PSV for 820 patients evaluated 1-month post-transplant measured 206 cm/s; RAA PSV exceeded 250 cm/s in 224 patients (27%). Mean RAA PSV for 785 patients evaluated 4-month post-transplant measured 203 cm/s; RAA PSV exceeded 250 cm/s in 201 patients (26%). Mean RAA PSV for 766 patients evaluated 1-year post-transplant measured 189 cm/s; RAA PSV exceeded 250 cm/s in 141 patients (18%). At each of the given time points, 24%-34% of normal patients had RAA-to-EIA ratios greater than 1.8. Approximately, 26% of patients without TRAS have RAA PSV > 250 cm/s in the first 9 months, and 18% do at 1 year. Similar findings also occurred with regards to the RAA-to-EIA ratio threshold of 1.8. In isolation, a PSV over 250 cm/s or 1.8 ratio threshold for suspicion of TRAS will lead to a large number of false-positive assessments.

    Following transplantation (TX) of both renal and non-renal organs, a large proportion of patients have renal dysfunction. There are multiple causes for this. Chronic nephrotoxicity and high doses of calcineurin inhibitors are important factors. Preoperative and perioperative factors like...... hypertension, hypotension, drugs and infections may play a causative role as well. Organ-specific causes include hepatorenal syndrome, cirrhosis, low cardiac function, low respiratory function and diabetes developed both before and after TX. It is important to be able to perform precise and valid measurements...

    Full Text Available Tinea capitis rarely occurs in renal transplant recipients. We report this living-related renal transplant patient receiving cyclosporine-based therapy who initially presented with severe exfoliation of the scalp with yellowish-white scales and marked hair loss. The lesions extended to the frontal area and both cheeks, resulting in several skin ulcers with perifocal erythematous inflammatory changes, and palpable cervical lymph nodes. A biopsy of a skin lesion revealed fungal infection and culture yielded Microsporum canis. The patient mentioned an outbreak of ringworm in her breeding dogs during this period. After adequate treatment of the patient and her infected animals with griseofulvin and disinfection of the environment, her skin lesions resolved dramatically, with regrowth of hair.

    This cross-sectional study evaluated the prevalence of major depressive disorder and depressive symptoms in children and adolescents after renal transplantation. A total of 71 patients who had undergone renal transplantation were interviewed in person using the Farsi (Persian) version of the Kiddie Schedule for Affective Disorders and Schizophrenia and Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria. Major depressive disorder, depressive symptoms, and suicidal behaviors were assessed. The rate of major depressive disorder was 2.8%; two-thirds of the patients had irritability; and approximately 40% had recurrent thoughts of death and suicidal ideation. The rate of major depressive disorder was lower than in other chronic diseases such as thallasemia or hemophilia; however, the rate of suicidal behaviors was high.

    Full Text Available There are more than 200,000 end stage renal disease (ESRD patients who are potential transplant candidates and more than 100,000 previously transplanted renal recipients with functioning allografts in the United States 1. Fifty-seven percent of these patients are male and forty percent are greater than 50 years of age 2, 3. Diabetes is the most common cause of kidney failure. It is evident that many patients are at high risk for development of urologic problems and thus it is estimated that the average urologist will care for up to ten of these patients yearly4. Thus a review of the genitourinary (GU evaluation and management of these patients is timely.

    Kidney transplantation is the treatment of choice for patients with end-stage renal disease. Despite improvements in short-term patient and graft outcomes, there has been no major improvement in long-term outcomes. The aim of this study was to determine the prevalence of cardiovascular risk factors, such as hypertension, dyslipidemia, diabetes, chronic kidney disease, and obesity, and the impact of their control among 526 stable renal transplant recipients according to the guidelines in the general population. Mean blood pressure was 133 +/- 16/81 +/- 9 mm Hg. The proportion of patients on antihypertensive therapy was 75%, and on ACE inhibitors or angiotensin II receptor blockers, 26%. The mean cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides were 195 +/- 41, 115 +/- 32, 51 +/- 17, and 137 +/- 75 mg/dL, respectively. The proportion of patients on statin treatment was 49.7%, and those with body mass indices between 25 and 30, 30 and 35, and >35 kg/m(2) were 35%, 15%, and 4%. We observed a high prevalence of chronic kidney disease, hypertension, dyslipidemia, and obesity among renal transplant patients. Suboptimal control was frequent and control of some of these complications was far below targets established for nontransplant patients despite progressive intensification of therapy with functional graft decline. The findings of this study may have an impact on the management of renal transplant recipients.

    Manifestations of breast abnormalities in these patients included breast calcifications, duct dilatation, fibrocystic change, rapidly enlarged multiple fibroadenomas, edema, invasive ductal cancer, extensive fibrosis, spontaneous hemorrhage, and Mondor's disease. These interesting cases we experienced are reported. Prolactin, growth hormone, and cortisol are required concurrently for normal development of mammary epithelium. Hormonal profile of chronic renal failure is different to normal person due to decreased renal clearance. The incidence of breast cancer is also increased in CRF. Metastatic soft tissue calcification is well described finding in chronic renal failure related to an increase in serum calcium phosphate product and secondary hyperparathyroidism. Kidney failure alone may increases prolactin level. The possibility of deranged hypothalamic-pituitary control mechanisms do not excluded. Impaired prolactin response to TRH stimulation has also been observed. Methyldopa and tricyclic antidepressants specifically were associated with hyperprolactinemia. Cyclosporin administration may elevate serum prolactin levels with simultaneous down regulation of prolactin receptors. Some populations of lymphocytes and fibroblasts exhibit cyclosporin receptors. Cyclosporin could potentially promote fibroadenomas by direct action, and seems to alter LH secretion.

  11. Ezetimibe as a potential treatment for dyslipidemia associated with chronic renal failure and renal transplant

    Full Text Available Individuals with chronic renal disease (CKD are prone to have accelerated process of atherosclerosis. Importantly, cardiovascular disease is the main cause of morbidity and mortality in kidney transplant recipients. Recent studies suggest a potential benefit of the lipid lowering medica-tions in preventing cardiovascular events in the CKD and the transplant populations. In particular, statin was shown to be effective in reducing low density lipoprotein (LDL-cholesterol. However, refractory dyslipidemia and difficulty in lowering LDL to target were reported with the CKD and the kidney transplant patients. The second United Kingdom Heart and Renal protection study (UK-HARP-II showed that the addition of ezetimibe to simvastatin was safe and effective in treating dyslipidemia in CKD. Furthermore, the combination of ezetimibe and statin was also effective and safe in treating dyslipidemia in kidney transplant recipients. The Study of Heart and Renal Pro-tection (SHARP trial will evaluate the effects of lowering LDL-C with ezetimibe 10 mg and simvastatin 20 mg daily versus placebo in 9,000 patients with chronic kidney disease. The current evidence suggests that the addition of ezetimibe to satin is effective and safe in treating dyslipidemia in the CKD and the kidney transplant patients. Future clinical trials are needed to determine whether ezetimibe will reduce cardiovascular risk in the CKD patients.

    We report here a case of complication of peritoneal implantation of ureter in cadaveric renal transplant. The patient presented with anuria and delayed graft function. The diagnosis was suspected upon physical examination and radiological investigation. The complication was managed with reimplantation of the ureter into the bladder and the patient recovered with good graft function. We discuss this case, review the literature on this rare complication, and share our suggestions on how it can be prevented.

    Kidneys from donors affected by autosomal-dominant polycystic kidney disease (ADPKD) are, in general, considered unsuitable for transplantation. However, some authors report cases of patients who received kidneys from a deceased ADPKD donor showing encouraging outcomes. Our aim is to provide our experience of a patient with end stage renal failure who received a deceased donor kidney from a 29-year-old who themselves had been diagnosed with ADPKD but well maintained renal function, and to provide a comprehensive review of all the published literature. In addition to our case, a literature search (PubMed database, Embase, Cochrane Library) of articles published between 1980 and 2017 was performed. Sixteen cases were identified. Median donor age was 24 (range12-55) years old. Median recipient age was 46 (range 19-72) years old. Fifteen cases had a single kidney transplant and one case had a dual kidney transplant. 13/16 (81%) had immediate function, 2 patients (12.5%) had delayed graft function and one patient (6.25%) had primary non-function. Median graft follow up was 36 months (range 6-180). Median serum creatinine at last follow up was 124 μmol/L (range75-442). Thirteen patients (81%) were still alive with a working renal transplant at last follow up. The published literature is encouraging and supports the use of polycystic kidneys from younger deceased donors. Therefore, we believe that if kidneys from ADPKD donors are offered, they should have a full assessment and be considered acceptable for renal donation to recipients who may have a life expectancy of 10 years or less and who are fully informed and have the capacity to consent to receiving a polycystic kidney.

    2010-04-01

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

    Full Text Available 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.

    Feasibility of photodynamic therapy (PDT) for secondary hyperparathyroidism (SHPT) was examined in a rat model of SHPT. A photosensitizer, 5-aminolevulinic acid (5-ALA), was injected intraperitoneally, and the parathyroid glands were irradiated either after surgical exposure with 385-nm light or transdermally with 630-nm light from a light-emitting diode (LED) lamp. PDT with high 5-ALA and irradiation doses caused severe hypoparathyroidism in SHPT rats within two days. Low-dose invasive PDT reduced intact parathyroid hormone (iPTH) levels in all rats from 748.9 ± 462.6 pg/mL at baseline to 138.7 ± 117.5 pg/mL at week 6, followed by a further decrease to 80.5 ± 54.0 pg/mL at week 9 in 60 % of rats or an increase to 970.0 ± 215.6 pg/mL at week 9 in 40 % of rats. Low-dose noninvasive PDT reduced iPTH levels from 1612.5 ± 607.8 pg/mL at baseline to 591.9 ± 480.1 pg/mL at week 4 in all rats. Thereafter, iPTH levels remained low in 43 % of rats and were 233.7 ± 51.6 pg/mL at week 9, whereas 57 % showed an increase, reaching 3305.9 ± 107.3 pg/mL at week 9. Control SHPT rats had iPTH levels of 2487.8 ± 350.9 and 2974.6 ± 372.1 pg/mL at week 4 and 9, respectively. The parathyroid glands of the rats with low iPTH levels were atrophied and had few parathyroid cells surrounded by fibrotic materials and no recognizable blood vessels. Those of the rats with high iPTH levels showed well-preserved gland structure, clusters of parathyroid cells, and blood vessels. These results demonstrate that 5-ALA-mediated PDT for SHPT is feasible.

    Full Text Available Background/Aim. Chronic renal insufficiency (CRI, diabetes, hypertension, autosomal dominant polycystic kidney disease (ADPKD are the main reasons for starting dialysis treatment in patients having kidney function failure. At present, dialysis treatments are performed in about 4,100 patients at 46 institutions in Serbia, out of which 90% are hemodialyses. At end-stage renal disease (ESRD the only correct selection is kidney transplatation. The basic aim of the planned research was to compare ratio of costs and effects (Cost Effectiveness Analysis - CEA of hemodialysis and kidney transplantation in patients at ESRD. Methods. As the main issue of treatment in patients from both groups the life quality measured by the validated McGill Questionary, was used. The study included 150 patients totally, divided into two groups. The study group consisted of 50 patients with kidney transplantation performed at the Clinical Center of Serbia and the control group consisted of 100 patients on hemodialysis at Clinical Center of Serbia, Clinical Hospital Center Zemun, Clinical Hospital Center 'Zvezdara', Clinical Center Kragujevac and Health Center 'Studenica', Kraljevo, comparable with respect to sex, age and length of treatment with the study group. Results. Effect of kidney transplantation in relation to hemodialysis being selection of treatment is expressed in the form of incremental ratio of costs and effects (Incremental Cost-Effectiveness Ratio - ICER. It is clear from the enclosed tables that the strategy of kidney transplantation is far more profitable considering the fact that it represents saving of EUR 132,256.25 per one year of contribution Quality Adjusted Life Years (QALY within the period of 10 years. According to all aspects of live quality (physical symptoms and problems, physical well-being, psychological symptoms, existential well-being and support, difference is statistically important in favor of transplant patents.

    Diana Vassallo

    2014-01-01

    Full Text Available An asymptomatic 35-year-old renal transplant recipient was noted to have deranged liver function tests. Liver biopsy revealed a portal inflammatory process with mild lobular activity and portal fibrous expansion, consistent with a virally mediated process. An extensive viral screen confirmed infection with Hepatitis E virus genotype 3 (HEV-3. There is increased awareness about locally acquired Hepatitis E virus (HEV infection in the transplant population in the UK. The important implications of this infection are becoming more apparent as progression to liver cirrhosis can occur. However, the incidence, natural history, and treatment of HEV infection in the transplant population are not well established. This report illustrates a case of delayed spontaneous clearance of the HEV infection.

  20. Recurrence and Treatment after Renal Transplantation in Children with FSGS

    Directory of Open Access Journals (Sweden)

    Hee Gyung Kang

    2016-01-01

    Full Text Available Focal segmental glomerulosclerosis (FSGS is a common cause of end-stage renal disease and a common pathologic diagnosis of idiopathic nephrotic syndrome (NS, especially in steroid-resistant cases. FSGS is known to recur after kidney transplantation, frequently followed by graft loss. However, not all patients with FSGS suffer from recurrence after kidney transplantation, and genetic and secondary FSGS have a negligible risk of recurrence. Furthermore, many cases of recurrence achieve remission with the current management of recurrence (intensive plasmapheresis/immunosuppression, including rituximab, and other promising agents are being evaluated. Therefore, a pathologic diagnosis of FSGS itself should not cause postponement of allograft kidney transplantation. For patients with a high risk of recurrence who presented with classical symptoms of NS, that is, severe edema, proteinuria, and hypoalbuminemia, close monitoring of proteinuria is necessary, followed by immediate, intensive treatment for recurrence.

    Full Text Available Fertility is improved within months and conception is achieved within one to six years after kidney transplantation. Pregnancy is safe and has little effect on long-term graft survival, but has increased maternal and fetal risks. Pregnancy is contraindicated in the first two years post-kidney transplantation due to increased risk of acute rejections and higher doses of immunosuppressive drugs. Poor renal function, uncontrolled diabetes mellitus and hypertension are other contraindications. Family planning and counseling, and consideration of a suitable contraceptive method are essential before transplantation. Tubal ligation and vasectomy are permanent contraceptives with the least failure results. Combined pills are highly effective and are among the lowest failure rate contraceptives, but they interact with cyclosporine, and are contraindicated in patients with thromboembolism and deep vein thrombosis. Progesterone-only minipill has the advantage of avoiding the risks associated with estrogen, but has a higher failure rate than the combined pills. The barrier methods (condom and diaphragm are effective and safe contraceptives and can prevent sexually transmitted diseases, but require motivated couples. Intra uterine devices are convenient contraceptives, but have higher failure rate and are associated with increased incidence of pelvic infection. Pregnancy in renal transplant recipients should be managed by a multidisciplinary approach in a tertiary centre.

    Autosomal dominant polycystic kidney disease (ADPKD), the most common form of polycystic kidney disease (PKD), is a disorder with characteristics of neoplasia. However, it is not known whether renal transplant recipients with PKD have an increased risk of cancer. Data from the Scientific Registry of Transplant Recipients, which contains information on all solid organ transplant recipients in the United States, were linked to 15 population-based cancer registries in the United States. For PKD recipients, we compared overall cancer risk with that in the general population. We also compared cancer incidence in PKD versus non-PKD renal transplant recipients using Poisson regression, and we determined incidence rate ratios (IRRs) adjusted for age, sex, race/ethnicity, dialysis duration, and time since transplantation. The study included 10,166 kidney recipients with PKD and 107,339 without PKD. Cancer incidence in PKD recipients was 1233.6 per 100,000 person-years, 48% higher than expected in the general population (standardized incidence ratio, 1.48; 95% confidence interval [95% CI], 1.37 to 1.60), whereas cancer incidence in non-PKD recipients was 1119.1 per 100,000 person-years. The unadjusted incidence was higher in PKD than in non-PKD recipients (IRR, 1.10; 95% CI, 1.01 to 1.20). However, PKD recipients were older (median age at transplantation, 51 years versus 45 years for non-PKD recipients), and after multivariable adjustment, cancer incidence was lower in PKD recipients than in others (IRR, 0.84; 95% CI, 0.77 to 0.91). The reason for the lower cancer risk in PKD recipients is not known but may relate to biologic characteristics of ADPKD or to cancer risk behaviors associated with ADPKD.

    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.

    End-stage renal disease is becoming a contemporary global concern with increasing prevalence. The available treatment strategies are limited to dialysis and renal transplantation. However, limited organ supply and autoimmune rejection are the shortcomings that limit widespread application of transplantation. Favorably, regenerative medicine is able to provide acellular natural scaffolds for renal transplantation. Experimental surgeries in animal models are a fundamental step in transplantation research. This video presents a practical method for transplantation of bilateral acellular kidneys in a rat model, which could serve as a key step for further research.

    Full Text Available A successful renal transplantation service was started in Nepal at the Tribhuvan Univer-sity Teaching Hospital in August 2008, and a continuing regular service is being provided currently to needy people. We report here our experience in thirty five end stage renal disease patients who re-ceived kidneys from close relatives during a one year period. The mean age of donors was 46.7 years. Seventeen (49% donations were from parents, 13 (37% from spouses, four (11% between siblings and one (3% between mother and daughter in law. Although the left kidney was given preference, right sided donor nephrectomy was needed in five (14% cases. Six (17% donors had minor post-operative problems. The mean age of recipients was 33.2 years, four (11% of whom had pre-emptive renal transplantation. Recipients were immunosuppressed with dacluzimab, prednisolone, mycophena-late, and cyclosporine or tacrolimus. The average time taken for graft implantation was 137 minutes. The mean cold ischemia time and second warm ischemia time were 133 and 36 minutes respectively. Four (11% patients developed urinary tract infection, three (9% had significant hematuria, one (3% developed a peri-transplant abscess, and one (3% had ureteric ischemia and urine leak which required re-exploration in the early post-operative period. Four patients (11% developed acute rejection of which three were cell- mediated rejection and one was antibody-mediated. There were two (6% deaths, one due to transplant-related sepsis and the other due to subarachnoid hemorrhage following rupture of a posterior communicating artery aneurysm. No kidney has been lost otherwise.

    We currently know that prostate cancer (Pca) risk is reduced in patients undergoing kidney transplantation. However, its impact and treatment are not widely studied. This was a retrospective study of male patients submitted to kidney transplantation in our center from 1980 to 2016 evaluating incidence, treatment, and follow-up of Pca in our population. In 1805 patients undergoing kidney transplantation, 20 men were diagnosed with Pca, leading to an incidence of 1.1%. Median age at renal transplantation was 53.4 years with a median age at diagnosis of Pca of 61.2 years. Initial median prostate-specific antigen (PSA) was 6 ng/mL and Gleason score was 7 (3 + 4) in about 50% of cases. Bone metastasis developed in 10% and no visceral metastases were diagnosed. The majority of patients were submitted to radical prostatectomy and bilateral pelvic lymph node dissection. Some other cancers occurred in these patients such as skin and pulmonary cancers. In 35% of the cases, the graft was lost. The main cause of patient death was cardiovascular. The mean graft survival was about 14 years. The majority of patients are alive with functioning grafts (65%). In our center the clinical incidence of Pca in patients undergoing kidney transplantation is 1.1% and surgical treatment seems to be a good initial option. Copyright © 2017 Elsevier Inc.

    Full Text Available With the increasing number of patients being offered kidney transplantation by many centers in the developing world, it is not unexpected that there would be attendant ethical and legal issues even when the selection process for transplantation seems medically justified. Because of the inadequate infrastructure for hemodialysis and peritoneal dialysis, coupled with the challenges of logistics for maintenance dialysis, transplantation would seem to be the best option for patients with end-stage renal failure, even in developed economies where these can easily be tackled. The main issues here revolve around incentives for donors, organ trade and trafficking and the economics of eliminating the waiting list and the criminal activities of organ trans-plantation. In the developing world, with the current level of corruption and poverty, there is a need to redouble efforts to monitor transplant activities. Professional bodies should take the lead in this regard. Furthermore, there is a need for governments to engage in public consultation and community awareness concerning organ donation in living and deceased persons.

    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.

    The aim of this study was to evaluate the incidence of posttransplant malignancy in kidney transplant patients and investigate the clinical and histopathologic features of these patients. We retrospectively reviewed information on donor and recipient characteristics, patient and graft survival, and cancer incidence after transplant for 867 kidney transplant patients. Patients with neoplasms prior to transplant were excluded. A follow-up study estimated cancer incidence after transplant. Neoplasms were diagnosed in 59 patients (6.8%), 41 men and 18 women; 22 (37.3%) had skin tumors, 19 (32.2%) had solid tumors, 10 (16.9%) had posttransplant lymphoproliferative disorders, and 8 (13.6%) had Kaposi sarcoma. The mean age at the time of malignant tumor diagnosis was 42.7 ± 13.6 years, and statistically significant differences were found between tumor groups (P < .01). The average latency period between transplant and diagnosis of malignant tumors was 99.8 ± 56.9 months for solid tumors, 78.4 ± 52 months for skin tumors, 64.5 ± 48.8 months for posttransplant lymphoproliferative disorders, and 13.5 ± 8.8 months for Kaposi sarcoma, with significant difference found between tumor groups (P < .01). Ten patients (16.9%) had more than 1 malignant tumor. Eighteen patients died, with a mean time to death of 31.5 ± 22.8 months after tumor diagnosis. A significant positive association was found between survival and the number of tumors (P = .001); 5-year survival after tumor diagnosis was 81% and 40% for patients with 1 malignant tumor and patients with more than 1 malignant tumor, respectively. Malignancy is a common cause of death after renal transplant. Early detection and treatment of posttransplant malignancies is an important challenge. Screening these patients for malignancies posttransplant is crucial, and efforts should be directed to define effective immunosuppressive protocols that are associated with a lower incidence of malignancy.

    To evaluate the impact of market competition on patient mortality and graft failure after kidney transplantation. Kidneys are initially allocated within 58 donation service areas (DSAs), which have varying numbers of transplant centers. Market competition is generally considered beneficial. The Scientific Registry of Transplant Recipients database was queried and the Herfindahl-Hirschman index (HHI), a measure of market competition, was calculated for each DSA from 2003 to 2012. Receipt of low-quality kidneys (Kidney Donor Profile Index ≥ 85) was modeled with multivariable logistic regression, and Cox proportional hazards models were created for graft failure and patient mortality. A total of 127,355 adult renal transplants were performed. DSAs were categorized as 7 no (HHI = 1), 17 low (HHI = 0.52-0.97), 17 medium (HHI = 0.33-0.51), or 17 high (HHI = 0.09-0.32) competition. For deceased donor kidney transplantation, increasing market competition was significantly associated with mortality [hazard ratio (HR): 1.11, P = 0.01], graft failure (HR: 1.18, P = 0.0001), and greater use of low-quality kidneys (odds ratio = 1.39, P Competition was associated with longer waitlists (P = 0.04) but not with the number of transplants per capita in a DSA (P = 0.21). Increasing market competition is associated with increased patient mortality and graft failure and the use of riskier kidneys. These results may represent more aggressive transplantation and tolerance of greater risk for patients who otherwise have poor alternatives. Market competition should be better studied to ensure optimal outcomes.

    Full Text Available Post-transplant lymphoproliferative disorder (PTLD is a well-recognized, but uncommon complication of organ transplantation. This study was a retrospective analysis of 2000 patients who underwent renal transplantation over a period of 30 years (1980-2010. Forty malignancies were diagnosed in 36 patients. Of these, 29 patients (1.45% had PTLD (7 females, 22 males accounting for 72.5% of all malignancies after transplantation. Twenty-two (75.8% developed non-Hodgkin lymphoma and seven patients (24.2% had myeloma. Diagnosis was made by biopsy of the involved organ in 21 patients (72.4% and aspiration cytology in five patients (17.2%. In three patients, the diagnosis was made only at autopsy. Mean age at the time of diagnosis of PTLD was 41.9 years (range 21-69 years. Time interval from transplantation to the diagnosis of PTLD ranged from 3 months to 144 months with a median of 48 months. Only five patients (17.2% developed PTLD within a year of transplantation. Twelve patients developed PTLD 1-5 years and 12 patients 5-10 years after transplantation. Organ involvement was extra nodal in 18 patients (82%. Thirteen (59% patients had disseminated disease and nine (41% had localized involvement of a single organ (brain-3, liver-1, allograft-1, perigraft node-1, retroperitoneal lymph nodes-3. Infiltration of the graft was noted in two patients. Patients with myeloma presented with backache, pathological fracture, unexplained anemia or graft dysfunction. PTLD was of B cell origin in 20 cases (70%. CD 20 staining was performed in 10 recent cases, of which 8 stained positive. Of the 26 patients diagnosed during life, 20 (69% died within 1 year of diagnosis despite therapy. In conclusion, PTLD is encountered late after renal transplantation in the majority of our patients and is associated with a dismal outcome. The late onset in the majority of patients suggests that it is unlikely to be Epstein Barr virus related.

    Full Text Available Renal secondary hyperparathyroidism is a complex clinical syndrome frequently described in dogs. However, in most cases, lesions are characterized by fibrous osteodystrophy of facial bones, affecting principally the mandible and the maxilla. There are few reports of renal secondary hyperparathyroidism associated with facial tumorous masses in the dog; similar findings in dogs have not been previously described in Brazil. This report describes the clinical, pathological, and radiological findings of this syndrome in a 14-month-old dog with oral tumorous-like lesions. The pathogenesis associated with this disease is also discussed.Hiperparatireoidismo renal secundário é uma síndrome clínica complexa freqüentemente descrita em cães.

    2013-04-01

    Full Text Available Background: Validity, reliability and clinical value of classical urinary parameters for transplant monitoring are controversial. Urinary parameters were analyzed regarding cost-effectiveness, frequency of urinary tract infection and prediction of renal graft function and rejection. Methods: Urinary parameters of the first two postoperative weeks of 120 renal transplant patients were retrospectively correlated with the postoperative course. Results: Creatinine levels were significantly different on each postoperative day between the groups with and without rejection. Osmolaluria, diuresis and serum creatinine are equivalent in predicting graft rejection. Osmolaluria is not suitable as a distinguishing criterion between graft rejection and other complications. Measurement of glucosuria has no diagnostic value. Proteinuria has no prognostic relevance regarding rejection, although proteinuria >0.5g/l occurred more often in patients with rejection. Despite antibiotic prophylaxis with co-trimoxazole, 41 of 120 patients (34% suffered from urinary tract infection (UTI; mostly E. coli within the first 14 days after transplantation. Conclusions: The measurement of some classical urinary parameters delivers no diagnostic gain. UTIs are frequent despite antibiotic prophylaxis, but the use of urine cultures makes sense only if a (cheaper semiquantitative test is positive.

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

  18. Diagnosis and management of ureteral complications following renal transplantation

    Directory of Open Access Journals (Sweden)

    Brian D. Duty

    2015-10-01

    Full Text Available When compared with maintenance dialysis, renal transplantation affords patients with end-stage renal disease better long-term survival and a better quality of life. Approximately 9% of patients will develop a major urologic complication following kidney transplantation. Ureteral complications are most common and include obstruction (intrinsic and extrinsic, urine leak and vesicoureteral reflux. Ureterovesical anastomotic strictures result from technical error or ureteral ischemia. Balloon dilation or endoureterotomy may be considered for short, low-grade strictures, but open reconstruction is associated with higher success rates. Urine leak usually occurs in the early postoperative period. Nearly 60% of patients can be successfully managed with a pelvic drain and urinary decompression (nephrostomy tube, ureteral stent, and indwelling bladder catheter. Proximal, large-volume, or leaks that persist despite urinary diversion, require open repair. Vesicoureteral reflux is common following transplantation. Patients with recurrent pyelonephritis despite antimicrobial prophylaxis require surgical treatment. Deflux injection may be considered in recipients with low-grade disease. Grade IV and V reflux are best managed with open reconstruction.

    Although many centers have reported their experience on maternal and perinatal outcomes in renal transplant recipients. Very few information can be found about the psychological aspects that may rise for these patients during pregnancy. Considering the importance of the psychological concerns for this kind of patients, we have developed a protocol to better assist renal transplant recipients during pregnancy and here we show what we have learnt. To understand how the maternal concerns are seen from renal transplant recipients in terms of psychological aspects. Fifteen pregnant kidney transplanted women with an average age of 27.5years were included in the study. All patients have been investigated beyond the 20th week of pregnancy to delivery. The study is cross-sectional, qualitative, and participation is based on developed phenomenological method. Final data analysis will be done through thematic analysis and hermeneutics of meaning. The only exclusion criteria were the current presence of psychiatric disorders or use of drugs that could influence cognitive and emotional aspects during the psychological evaluation. During the last two years we have observed in these women that all of them are aware of the risks of pregnancy after transplantation. Qualitative aspects were: Pregnant with kidney transplantation show: in relation to pregnancy, the desire to be mothers, to give a son to her husband, to become a healthy person again; they believe that conception is God's will, they have fear of pregnancy, ambivalence of feelings (fear and happiness). In relation to the graft, they reported fear of baby malformations, fear and anguish of graft loss, still consider it worth the risk of having the baby, and some women name the graft, if it were another infant. In relation to delivery, state anxiety and anguish at the proximity of labor (fear of labor pain, anesthesia, cesarean section, vaginal delivery and the "psychic pain"). Pending the final results of this study, we

    The subtotally nephrectomized rat has often been used to investigate the etiology and treatment of secondary hyperparathyroidism (secondaryHPT), but it has been used less frequently to study the effects of secondaryHPT on bone. The recent development of a reliable and specific rat parathyroid hormone (PTH) immunoradiometric assay has provided an opportunity for a thorough investigation of the relationship between circulating, biologically active PTH, and the skeletal abnormalities that occur in chronic renal insufficiency (CRI). Rats were 5/6 nephrectomized (Nx) or sham operated and fed diets with varying levels of Ca and P for 12-14 weeks to induce differing magnitudes of secondaryHPT. Parathyroid gland volume increased by 80%-90% in 5/6 Nx rats in the mild and moderate secondaryHPT groups (2.3- and 7.7-fold higher PTH levels, respectively) and by 3.3-fold in the severe secondaryHPT group (12-fold increase in PTH). The increases in gland volume were caused primarily by cell hyperplasia. Mild secondaryHPT resulted in a 12% decrease in bone mineral density (BMD) across the entire femur, increased osteoclast numbers (N.Oc), unchanged osteoblast numbers (N.Ob), and decreased cancellous bone volume (Cn.BV) in the tibial metaphysis but, apart from increased marrow area, no major changes in cortical bone at the tibio-fibular junction. Moderate secondaryHPT was associated with no changes in femoral BMD, or in tibial Cn.BV, but N.Ob and bone formation rate (BFR) were markedly elevated. Increased periosteal, intracortical, and endocortical BFR and turnover were evident, and contributed to increased cortical porosity (Ct.Po). The changes were exaggerated in the severe secondaryHPT group; BMD was lower in the proximal, but higher in the distal femur, and Cn.BV, N.Ob, N.Oc, and BFR were increased by six-, seven-, three-, and 30-fold, respectively. Endocortical BFR was elevated 31-fold and the extensive Ct.Po (10%) decreased bone strength. However, Ct.Po was not apparent until

    Rotational digital subtraction angiography (RDSA) allows multidirectional angiographic acquisitions with a single injection of contrast medium. The role of RDSA was evaluated in 60 patients referred over a 7-month period for diagnostic renal angiography and 12 patients referred for renal transplant studies. All angiograms were assessed for their diagnostic value, the presence of anomalies and the quantity of contrast medium used. The effective dose for native renal RDSA was determined. 41 (68.3%) native renal RDSA images and 8 (66.7%) transplant renal RDSA images were of diagnostic quality. Multiple renal arteries were identified in 9/41 (22%) native renal RDSA diagnostic images. The mean volume of contrast medium in the RDSA runs was 51.2 ml and 50 ml for native and transplant renal studies, respectively. The mean effective dose for 120 degrees native renal RDSA was 2.36 mSv, equivalent to 1 year's mean background radiation. Those RDSA images that were non-diagnostic allowed accurate prediction of the optimal angle for further static angiographic series, which is of great value in transplant renal vessels.

    Chronic illnesses can cause wide range of personality and behavioral disorders and require appropriate evaluation. Poor patient compliance with prescribed medications and other aspects of management can affect the outcome towards undesirable situation. The setting of renal transplantation presents a broad spectrum of problems and consequences. People involved (patients, their families or treating physicians) have lifelong commitment with evaluation and implementation of measures towards resolving the issues. Psychiatric evaluation is part of this scenario, which starts with evaluation of organ recipient along with donor and family as whole, right from time of diagnosis of end organ failure to transplant and then lifelong. This review highlights common issues faced at different stages of this lengthy pathway.

    Full Text Available Background: Skin lesions - benign and malignant - occur frequently in organ transplant recipients receiving long-term immunosuppressive therapy. These patients are at greater risk of skin cancers. Aims: To study dermatologic problems in renal transplant recipients (RTRs. Methods: One hundred patients (53 men and 47 women were consecutively examined for benign and malignant skin complications since transplantation in Razi Hospital in Tehran Medical University. The main immunosuppressive therapy regimen in these patients was a combination of prednisolone, azathioprine, and cyclosporine. Results: The early and most common complication was cosmetic side effects that occurred in 98% patients. Skin infections occurred in 83% of the patients and most of them were viral infections (65%, especially of human papilloma viruses (HPVs in 40% of the patients. We found six cases of malignancy in these patients in that four cases were skin cancers, including one case of SCC, one BCC, and two cases of Kaposi′s sarcoma. Dermatologic problems occur most frequently in RTRs, especially skin cancers which have higher frequency in these patients than general population, particularly, Kaposi sarcoma. Sun exposure has an important role in developing epithelial skin cancers following transplantation. The age of developing skin cancer in these patients was early than normal population. Conclusion: Our results emphasize the importance of dermatologic examinations and monitoring RTRs to obtain an early diagnosis and treatment of cutaneous manifestations.

    Delayed graft function (DGF) after renal transplantation can be diagnosed according to several different definitions, complicating comparison between studies that use DGF as an endpoint. This is a particular problem after transplantation with kidneys from donation after circulatory death (DCD) kidneys, because DGF is common, and its relationship to early graft failure may differ depending on the definition of DGF. The presence of DGF in 213 donation after brain death (DBD) and 312 DCD kidney transplants from October 2005 to August 2011 was determined according to 10 different, but widely used, definitions (based on dialysis requirements, creatinine changes, or both). The relationship of DGF to graft function and graft survival was determined. The incidence of DGF varied widely depending on the definition used (DBD; 24%-70%: DCD; 41%-91%). For kidneys from DCD donors, development of DGF was only associated with poorer 1-year estimated glomerular filtration rate for 1 of 10 definitions of DGF, and no definition of DGF was associated with impaired graft survival. Conversely, for DBD kidneys, DGF, as defined in 9 of 10 different ways, was associated with poorer 1-year estimated glomerular filtration rate and inferior graft survival. Importantly, the predictive power for poorer transplant outcome was comparable for all definitions of DGF. No definition of DGF is superior. We suggest that the most widely used and most easily calculated definition--the use of dialysis in the first postoperative week--should be universally adopted as the definition of DGF clinically and as a study endpoint.

    Full Text Available A 30-year-old female was symptomatic with headache, fatigue, and weakness since October 2011 and was told to have anemia. In January 2012, she was admitted outside with pulmonary edema. Investigations revealed advanced azotemia, anemia, and hypercalcemia. Urine showed 2 + proteins and 30–35 red blood cells. There was no history of oral ulcers, rash, Raynaud's phenomenon, or hemoptysis. She was evaluated for causes of rapidly progressive “renal failure.” Hemolytic work-up; antinuclear antibody, double-stranded DNA, and anti-neutrophil cytoplasmic antibody were negative. Kidney biopsy was done and interpreted as acute interstitial nephritis with hyaline casts. She was started on hemodialysis and treated with steroids and cyclophosphamide. She came to our institute in January 2012. Investigations showed evidence of paraproteinemia with kappa restriction. Bone marrow showed 15% plasma cells. Kidney biopsy was reviewed and was diagnostic of cast nephropathy. She was treated with 6 monthly cycles of dexamethasone and bortezomib. She achieved complete remission in July 2012. Maintenance doses of bortezomib were continued until May 2014. Autologous bone marrow transplantation was performed on June 06, 2014. Monthly, bortezomib was continued till April 2015. Subsequently, workup for renal transplantation was started with her father as her donor. Test for sensitization was negative. Renal transplantation was done on January 1, 2016, with prednisolone, mycophenolate, and tacrolimus. She achieved a serum creatinine of 0.6 mg% on the 4th postoperative day. Thereafter, she continues to remain stable.

    The surgical issues of renal transplantation (RT) after localized prostate cancer (PC) treatment and oncological outcomes after transplantation in patients on the waiting list with a history of PC were unknown. We conducted a retrospective multicentre study including all patients with PC diagnosed before the kidney transplantation. Fifty-two patients were included from December 1993 to December 2015. The median age at diagnosis of PC was 59.8years old. The median PSA rate at diagnosis was 7ng/mL. Twenty-seven, Twenty-four, and one PC were respectively low, intermediate and high risk according to d'Amico classification. Forty-three patients were treated by radical prostatectomy (RP): 28 retropubic, 15 laparoscopic and 3 by a perineal approach. Eighteen patients had a lymph node dissection. Four patients were treated with external radiotherapy and 2 by brachytherapy. Eight patients underwent radiotherapy after surgery. The median time between PC treatment and RT was 35.7 months. The median operating time for the renal transplantation was 180min (IQR 150-190; min 90-max 310) with a median intraoperative bleeding of 200mL (IQR 100-290; min 50-max 2000). A history of lymphadenectomy did not significantly lengthen operative time (P=0.34). No recurrence of PC was observed after a median follow of 36months. PC discovered before RT should be treated with RP to assess the risk of recurrence and decrease waiting for a RT. If the PC is at low risk of recurrence, it seems possible to shorten the waiting time before the RT after a multidisciplinary discussion meeting. 4. Copyright © 2017 Elsevier Masson SAS.

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

    A 45-year-old male recipient of a renal allograft was admitted because of a giant oesophageal ulcer coinciding with leucopoenia. An extensive workup revealed no explanation for the ulcer and leucopoenia. Our final diagnosis by exclusion was an idiopathic giant oesophageal ulcer and late-onset neutropenia as consequences of rituximab induction therapy given during the transplant procedure. The patient fully recovered after treatment with prednisone. However, after four months, the ulcer and leucopoenia recurred and again successfully responded to treatment with prednisone.

    Urinary lithiasis represents an unusual urologic complication in renal transplantation, with an incidence of 0.17%-1.8%.We present our experience with renal graft lithiasis in our series of renal transplantations. We reviewed the medical records for 2045 patients who underwent kidney transplantation from January 1983 to July 2013. Among the grafts, 9 patients were found to have allograft lithiasis. In 6 cases, the calculi were localized within the renal unit, and in 3 cases in the ureter. Two of the patients had relapsed after a few years from the first treatment. In both of them the stones were localized again in the ureter. In our series, incidence of graft lithiasis was 0.44% (n = 9). Three of the 9 patients (33.3%) were treated via percutaneous nephrolithotripsy (PCNL), 3 (33.3%) underwent extracorporeal shockwave lithotripsy (ESWL), 2 (22.2%) passed their stones spontaneously, and 1 (11.1%) underwent PCNL after 2 failed ESWL interventions. All patients are currently stone free but still remain under close urologic surveillance. Urinary stone formation can lead to significant morbidity and graft loss. The treatment options should be similar to those for patients in the general population. Long-term follow-up is substantial to determine the outcome and to prevent the recurrence.

    Conclusions: Major vascular complications are relatively uncommon after renal transplantation but still constitute an important cause of graft loss in early postoperative period. Aneurysm and vessel thrombosis usually require graft nephrectomy. Transplant renal artery stenosis is amenable to correction by endovascular techniques.

    Renal function deteriorates in about half of patients undergoing other transplants. We report the results of 105 renal biopsies from 101 nonrenal transplant recipients (bone marrow 14, liver 41, lung 30, heart 20). Biopsy indications were protracted acute renal failure (9%), creatinine increases (83%), heavy proteinuria (22%), or renal insufficiency before re-transplantation (9%). Histological findings other than nonspecific chronic changes, hypertension-related damage, and signs of chronic CNI toxicity included primary glomerular disease (17%), mostly after liver transplantation (21%) or after bone marrow transplantation (29%), and thrombotic microangiopathy (TMA) namely (10%). TMA had the most serious impact on the clinical course. Besides severe hypertension, one TMA patient died of cerebral hemorrhage, 5 had hemolytic-uremic syndrome, and 6 rapidly developed end-stage renal failure. TMA patients had the shortest kidney survival post-biopsy and, together with patients with acute tubular injury, the shortest kidney and patient survival since transplantation. Nine TMA patients had received CNI, 3 of them concomitantly received an mTOR-inhibitor. CNI toxicity is implicated in most patients with renal failure after transplant of other organs and may play a role in the development of TMA, the most serious complication. However, decreased renal function should not be routinely ascribed to CNI. © 2010 The Authors Journal compilation © 2010 The American Society of Transplantation and the American Society of Transplant Surgeons.

    2014-06-16

    In Mexico, diabetes mellitus is the main cause of end - stage kidney disease, and some patients may be transplant candidates. Organ supply is limited because of cultural issues. And, there is a lack of standardized clinical guidelines regarding organ donation. These issues highlight the tension surrounding the fact that living donors are being selected despite being prediabetic. This article presents, examines and discusses using the principles of non-maleficience, autonomy, justice and the constitutionally guaranteed right to health, the ethical considerations that arise from considering a prediabetic person as a potential kidney donor. Diabetes is an absolute contraindication for donating a kidney. However, the transplant protocols most frequently used in Mexico do not consider prediabetes as exclusion criteria. In prediabetic persons there are well known metabolic alterations that may compromise the long - term outcomes of the transplant if such donors are accepted. Even so, many of them are finally included because there are not enough donor candidates. Both, families and hospitals face the need to rapidly accept prediabetic donors before the clinical conditions of the recipient and the evolution of the disease exclude him/her as a transplant candidate; however, when using a kidney potentially damaged by prediabetes, neither the donor's nor the recipient's long term health is usually considered.Considering the ethical implication as well as the clinical and epidemiological evidence, we conclude that prediabetic persons are not suitable candidates for kidney donation. This recommendation should be taken into consideration by Mexican health institutions who should rewrite their transplant protocols. We argue that the decision to use a kidney from a living donor known to be pre-diabetic or from those persons with family history of T2DM, obesity, hypertension, or renal failure, should be considered unethical in Mexico if the donor bases the decision to

    More than other operations on the body, organ transplantation has a psychological resonance relating to the self and body image representation, both in donors and in recipients. In the medical literature there are many psychopathological patterns related to ESRD and to the changes in psychologic assessment and lifestyle after transplantation. Similar changes have been found in living donors. Forty-eight donor-recipient couples were evaluated before and 4 months after transplantation, using clinical interview, according to the DSM IV TR criteria; The structured Interview for renal transplantation, both for recipients and for donors; psychodiagnostic tests: mini-mental state; Hamilton Rating Scale for Depression; Hamilton Anxiety Scale; Self-Rating Anxiety Scale; Short-Form 36 Health Survey Questionnaire. Comparisons by paired Students t tests showed a significant Hamilton depression variation among recipients, with improvement in the gained score and reduction of depressive symptom (Hamilton score >7) frequency from 45.8% to 32%, and a decreased proportion of patients with a score >18 from 16.4% to 0%. There was no significant Hamilton Depression variation among donors, but there was somehow a reduction in depressive symptom frequency (Hamilton score >7) from 37.5% to 33.3% and a decrease among >18 scores from 12.6% to 0% patients. Living donor kidney transplantation did not adversely affect the lives of donors and significantly improved many aspects of the lives of recipients. However, physical and psychological aspects may be impaired by living donation. Careful donor selection, with appropriate pretransplantation psychiatric consulting, allows those with a normal life quality to donate without consequence to their physical or psychological status.

    2015-02-01

    Full Text Available Laparoscopic renal autotransplantation has serious perturbations on the body's homeostasis due to its non physiological positioning, use of pneumoperitoneum, changing fluid strategy at different points of time and on-going steps to maintain optimal environment for the transplanted kidney. Generally speaking, the anaesthetic management of renal auto-transplantation by open technique is not very complex and the perioperative management can be categorized in the intermediate level of clinical skill requirement. Adding to the comfort of the anaesthesiologist is the fact that these patients are not in end stage renal disease state and does not manifest the comorbidities, multisystem involvement and technical complexities of long term renal dysfunction and renal replacement therapy. In our case report surgeons used the da Vinci surgical robotic system for laparoscopic transplantation of the kidney at a new site. In this article we discuss the anaesthetic challenges of robot assisted laparoscopic renal auto-transplantation along with a description of our index case.

    Acute rejection (AR) remains the primary risk factor for renal transplant outcome; development of non-invasive diagnostic biomarkers for AR is an unmet need. We used shotgun proteomics using LC-MS/MS and ELISA to analyze a set of 92 urine samples, from patients with AR, stable grafts (STA), proteinuria (NS), and healthy controls (HC). A total of 1446 urinary proteins were identified along with a number of NS specific, renal transplantation specific and AR specific proteins. Relative abundance of identified urinary proteins was measured by protein-level spectral counts adopting a weighted fold-change statistic, assigning increased weight for more frequently observed proteins. We have identified alterations in a number of specific urinary proteins in AR, primarily relating to MHC antigens, the complement cascade and extra-cellular matrix proteins. A subset of proteins (UMOD, SERPINF1 and CD44), have been further cross-validated by ELISA in an independent set of urine samples, for significant differences in the abundance of these urinary proteins in AR. This label-free, semi-quantitative approach for sampling the urinary proteome in normal and disease states provides a robust and sensitive method for detection of urinary proteins for serial, non-invasive clinical monitoring for graft rejection after

    Full Text Available Este trabalho teve foco na investigação das atribuições de significados ao transplante renal de pacientes com Insuficiência Renal Crônica (IRC de um Hospital Universitário da Região Sul. Foi utilizado um método qualitativo e participaram doze pessoas na pesquisa. Os instrumentos utilizados foram a entrevista semidirigida e a autofotografia. Para a análise dos dados foi empregada a técnica de análise de conteúdo, o que permitiu que fossem construídas quatro categorias temáticas: a ansiedade da espera, os conflitos ante o doador, as expectativas em relação ao devir e a vida antes e depois do transplante. Constatou-se que a possibilidade deste traz consigo uma série de repercussões psíquicas devido o fato de ser visto como algo que restitui a vida, proporciona bem-estar e sentimento de liberdade, mesmo levando em consideração que ainda persistem os cuidados com o corpo, com a alimentação e com os remédios

    A separate subset of Granzyme B (GrB) producing B-cells regulating T-cell mediated immunity has been identified. In the present study, we investigated the role of GrB(+) B-cells in renal transplant patients (RTX). 12 healthy controls (HC) and 26 RTX patients were enrolled. In addition, 19 healthy volunteers treated with cyclosporine A (CsA) were enrolled. GrB(+) B-cells were determined via flow cytometry. RTX Patients showed a diminished fraction of GrB(+) B-cells as compared to HC. CsA treatment of healthy volunteers had no impact on the development of GrB(+) B-cells. RTX patients with a history of allograft rejection showed an increased frequency of GrB(+) B-cells. RTX patients with at least one episode of CMV viremia tended to have lower GrB(+) B-cells as compared to patients without viremic episodes. We demonstrate that treatment with CsA does not impair the development of GrB(+) B-cells. GrB(+) B-cells may have a dual role in renal transplantation as regulatory cells to maintain allospecific tolerance and as effector cells enhancing viral control. Copyright © 2017 Elsevier Inc.

    Full Text Available Calcineurin inhibitors remain an integral component of immunosuppressive therapy regimens following solid organ transplantation. Although nephrotoxicity associated with these agents is well documented, type IV renal tubular acidosis is a rare and potentially underreported complication following liver transplantation. Hepatologists must be able to recognize this adverse effect as it can lead to fatal hyperkalemia. We describe a case of tacrolimus-induced hyperkalemic type IV renal tubular acidosis in a patient following an orthotopic liver transplant for alcoholic cirrhosis.

    1989-06-01

    Within two years we have had the opportunity of observing seven leukemic children who were referred to our Pediatric Nephrology Unit for delayed renal failure following bone marrow transplantation (BMT). These children (3 to 12 years old), six with acute lymphoblastic leukemia (ALL) and one with acute non-lymphoblastic leukemia (ANLL), underwent BMT (4 autologous BMT, 3 allogeneic BMT) after the first remission in two, and after the second remission in five. Preparative regimen for BMT included cyclosphosphamide in three, cyclosphosphamide, vepeside and cytosine A in four, and a total body irradiation in a single dose of 10 grays (1000 R) in all of them. Three children were treated immediately after grafting with low dose cyclosporine for four to six months. Five to 10 months after BMT, four patients developed a hemolytic uremic syndrome with severe hypertension. The remaining three were found to have isolated renal insufficiency several months post-BMT. In the seven patients, renal biopsy showed a uniform pattern of severe glomerular involvement characterized by extensive lesions of mesangiolysis associated with severe arteriolonecrosis. A repeat biopsy performed one year later, in two patients showed severe scarring of the renal parenchyma with minor lesions of mesangiolysis. The similarity of the pathologic features observed suggests that the same mechanism might have been operative in the seven patients. It is very likely that the nephropathy is related to total body irradiation enhanced by chemotherapy. We conclude that current treatments of high risk leukemia might become a new cause of chronic renal failure. Further investigations are needed to know the exact incidence of this complication.

    Failed renal allografts often are left in situ in patients who revert to chronic dialysis therapy or who undergo retransplantation. These organs may be the site of massive calcification despite their lack of physiological function. Calcification of an endstage renal allograft is sometimes found incidentally. We report here two patients who developed extensive calcification of the renal graft, one was on chronic hemodialysis and the other had a second renal transplantation with normal renal function. The precise pathogenesis of calcification and the factors which determine its tissue localization are unclear. Factors postulated to promote the development of metastatic calcification include an elevated calcium phosphate product, severe secondary hyperparathyroidism, aluminium toxicity and duration of dialytic therapy. In some cases local factors related with the chronic inflammatory rejection process are probably involved as well. However, the exact relative contribution of these factors remains unresolved. Unless specific clinical indications are present, transplant nephrectomy is not necessary for calcified end-stage renal allografts.

    Chronic renal transplant dysfunction is one of the leading causes of graft failure in kidney transplantation. A complex interplay of both alloantigen-related and alloantigen-unrelated risk factors is believed to underlie its development. We propose that advanced glycation end products (AGEs) are

    Full Text Available Cardiovascular disease is a leading cause of mortality in renal transplant recipients. Coronary artery calcification (CAC has been found to have good correlation with atherosclerosis and cardiovascular morbidity. The objective of our study was to assess the prevalence of CAC and the long-term effects of renal transplantation on CAC and carotid intima-medial thickness (CIMT in Indian renal transplant recipients. Twenty-eight renal transplant recipients were included in this prospective study. Dual-source computed tomography and calcium scoring using Agatston′s method and CIMT measurement were performed at the time of transplant and then repeated at six and 12 months after transplantation. The prevalence of CAC in our study patients was low (32%, probably because they were young, had been on dialysis for a short duration and had undergone live-related renal transplant. An overall improvement in biochemical parameters was observed after transplantation. Patients with zero baseline calcium score did not show progression. Patients with baseline calcium score more than zero showed initial progression at 6 months and no further progression afterwards. There was good correlation between CIMT and CAC score. Our study suggests that renal transplantation does not reverse the calcification but appears to decrease the rate of progression in the long term.

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

    Chronic transplant dysfunction explains the majority of late renal allograft loss and is accompanied by extensive tissue remodeling leading to transplant vasculopathy, glomerulosclerosis and interstitial fibrosis. Matrix proteoglycans mediate cell-cell and cell-matrix interactions and play key roles in tissue remodeling. The aim of this study was to characterize differential heparan sulfate proteoglycan and chondroitin sulfate proteoglycan expression in transplant vasculopathy, glomerulosclerosis and interstitial fibrosis in renal allografts with chronic transplant dysfunction. Renal allografts were transplanted in the Dark Agouti-to-Wistar Furth rat strain combination. Dark Agouti-to-Dark Agouti isografts and non-transplanted Dark Agouti kidneys served as controls. Allograft and isograft recipients were sacrificed 66 and 81 days (mean) after transplantation, respectively. Heparan sulfate proteoglycan (collXVIII, perlecan and agrin) and chondroitin sulfate proteoglycan (versican) expression, as well as CD31 and LYVE-1 (vascular and lymphatic endothelium, respectively) expression were (semi-) quantitatively analyzed using immunofluorescence. Arteries with transplant vasculopathy and sclerotic glomeruli in allografts displayed pronounced neo-expression of collXVIII and perlecan. In contrast, in interstitial fibrosis expression of the chondroitin sulfate proteoglycan versican dominated. In the cortical tubular basement membranes in both iso- and allografts, induction of collXVIII was detected. Allografts presented extensive lymphangiogenesis (pproteoglycans being expressed are tightly associated with tissue remodeling after renal transplantation. Therefore, proteoglycans might be potential targets for clinical intervention in renal chronic transplant dysfunction.

    Patients with end-stage renal disease have two therapeutic options, dialysis and renal transplantation. Infectious complications occurring in such patients will not only condition the effectiveness of such treatments, but are among the main causes of morbidity and mortality in such cases. Knowledge of the advantages and limitations of nuclear techniques is essential for management of these conditions. (author)

    1974-01-01

    Renal failure of 4 wk duration in rats led to parathyroid enlargement, increased bone resorption, and decreased tubular reabsorption of phosphate by the remnant kidney. The degree of hyperparathyroidism was influenced by each of the three dietary factors investigated. In the first study increasing calcium intake reduced the size of the parathyroids by increasing calcium and reducing phosphate absorption. In the second study phosphate intake was linearly related to parathyroid gland size in the uremic animals and associated with rising plasma phosphate levels. In the last study acidosis led directly to increased bone resorption but small parathyroid glands associated with elevated ionized calcium levels. Alkalosis lowered the serum ionized calcium and led to parathyroid enlargement and the expected associated findings. It was shown that parathyroid weight reflected both metabolic activity as judged by amino acid uptake, and the content of immunoassayable parathyroid hormone. In all studies gland weight was inversely related to serum ionized calcium. PMID:4808640

    Chronic Kidney Disease (CKD) is a common health problem affecting 1 in 12 Americans. It is associated with elevated risks of mortality, cardiovascular disease, and high costs for the treatment of renal failure with dialysis or transplantation. Advances in CKD care are impeded by the lack of biomarkers for early diagnosis, assessment of the extent of tissue injury, estimation of disease progression, and evaluation of response to therapy. Such biomarkers should improve the performance of existing measures of renal functional impairment (estimated glomerular filtration rate, eGFR) or kidney damage (proteinuria). MicroRNAs (miRNAs) a class of small, non-coding RNAs that act as post-transcriptional repressors are gaining momentum as biomarkers in a number of disease areas. In this review, we examine the potential utility of miRNAs as promising biomarkers for renal disease. We explore the performance of miRNAs as biomarkers in two clinically important forms of CKD, diabetes and the nephropathy developing in kidney transplant recipients. Finally, we highlight the pitfalls and opportunities of miRNAs and provide a broad perspective for the future clinical development of miRNAs as biomarkers in CKD beyond the current gold standards of eGFR and albuminuria.

    This report shows our conclusions on the clinical, biochemical and densitometry characteristics of 35 normocalcemic primary hyperparathyroidism (PHPT) patients. This condition is defined by a high level of intact parathyroid hormone (iPTHI) with persistently normal serum and ionized calcium in the absence of secondary hyperparathyroidism. Our selection consisted of 30 women (90%) and 5 men (10%). The control group of 55 hypercalcemic patients with primary hyperparathyroidism included 51 women (93%) and 4 men (7%). The average age at diagnosis of normocalcemic PHPT was 61.4 ± 11.7 years and 56.4 ± 11.3 years in hypercalcemic PHPT. Besides the expected differences in serum calcium, ionized calcium, phosphorus and 24 h urinary calcium, we found no significant changes in other biochemical variables, and no differences in densitometry evaluations such as the presence of osteopenia or osteoporosis and the number of fractures in the two types of PHPT. But there was a significant difference in the presence of renal lithiasis between normocalcemic PHPT (11.4%) and clasic PHPT (49.1%) p < 0.0005, to some extent associated to the presence of hypercalciuria in classic PHPT. Two of the 35 patients with normocalcemic PHPT became classic hypercalcemic PHPT over a 4 year follow-up period. Our findings support the hypothesis that the normocalcemic PHPT could be an early stage of the classic PHPT, both having similar clinical effects to metabolic renal and bone levels.

    The newly transplanted kidney is difficult to monitor with regard to postoperative vascular thrombosis, especially when there is delayed graft function. We evaluated microdialysis as a tool for early ischemia detection in porcine kidneys with delayed graft function early after transplantation. Sixteen pigs were transplanted with 26-hr cold ischemia kidneys. A microdialysis catheter was placed in the lateral renal cortex. Five hours after graft reperfusion, the pigs were randomized to renal arterial clamping or open artery, n=8 in each group, and further observed for 2 hr. The diuresis and glomerular filtration rate were low and decreasing throughout the study, with no significant differences between groups. Until arterial clamping, there were no significant differences in the development of local renal metabolites between the two groups. Renal artery clamping immediately caused significantly different development of all metabolites (Pmonitoring and detection of thrombosis after renal transplantation.

    Full Text Available Post-transplant hypertension is a major risk factor for graft loss and patient survival; therefore, hypertension following renal transplantation must be treated strictly. There seems to be a strong association between hypertension, total body water (TBW and dry weight. In this study, we report the relationship of body water and body composition with hypertension in post-renal transplant patients. Forty-five post-transplant patients were enrolled in the study. Blood pressure (BP was labeled as controlled if BP was 120/80 mm Hg and not under good control if BP was above 120/80 mm Hg. Based on the number of antihypertensive medications a patient was taking, patients were divided into two groups: Group 1 patients on one antihypertensive drug and Group 2 patients on more than one antihypertensive drug. Nutritional status of the patients was assessed. Body composition (water compartments, body fat and lean mass was assessed using bioelectrical impedance analysis (BIA. Patient data were compared with 30 healthy volunteers. In patients, systolic BP was associated with TBW (P = 0.016, extracellular water (ECW Lt; r = 0.99, ECW% (r = 0.78 and diastolic BP with TBW% (P = 0.003, dry weight (r = 0.76 ECW% (r = 0.95 and percent intracellular water (ICW% (r = 0.79. Compared with controls, ECW and ECW% was higher in patients, and the ICW% was less in patients. There was significant difference in the actual weight of the patients and BIA-derived dry weight, although patients were clinically not edematous. The study showed a significant increase in diastolic BP with increase in dry weight. Significant difference in TBW was observed when the patients were grouped on the basis of the antihypertensive medication a patient was taking (one antihypertensive drug versus more than one antihypertensive drug. This study also showed an association between hypertension and overhydration. BIA may be a useful tool for the clinical assessment of overhydration in non

    Cytomegalovirus (CMV) infection is frequent in kidney transplant recipients. Although involvement of the gastrointestinal tract with CMV has been described, intra-oral localization is rare. The aim of this study was to analyze the incidence, clinical characteristics, treatment, and outcome of renal transplant recipients with oral lesions due to CMV. We analyzed the records of 453 patients who underwent kidney transplantation between February 1989 and March 2007. Incident cases and characteristics of CMV oral lesions were ascertained retrospectively in the outpatient records. The cumulative incidence of 6 cases with oral ulcerations was 1.32%. The median follow-up (n = 453) was 61.84 +/- 50.68 months. The interval for the incidence of CMV oral ulcers after renal transplantation was 12.83 +/- 23.51 months. The affected oral locations included the buccal mucosa, hard palate, soft palate, tongue, and floor of the mouth. CMV cases showed no significant difference with regard to gender distribution, age at renal transplantation, renal transplant indication, type of immunosuppressive treatment, and donor/recipient CMV serological status before transplantation. The number of acute rejection episodes was significantly greater and time since transplantation was significantly shorter in CMV cases. CMV infection, which is common in renal transplant recipients, only rarely affects the mouth. Herein we have reported 6 patients who suffered oral ulcers due to CMV infection. An early diagnosis of these lesions is important to a successful outcome for these patients.

    The estimation of differential function (DF) in post-renal transplant patients (PRTPs) is challenging because of the different distances of the native kidneys (NKs) and transplant kidney (TK) to the gamma camera and because current commercial software allows evaluation of only 2 kidneys instead of 3. We retrospectively validated a simplified method (SM) to process renal scans and hypothesized that it is comparable with the reference method (RM). Twelve 99mTc MAG3 renal scintigraphies of 10 PRTPs were performed on a dual-head gamma camera. The RM was a 2-step process, with the left and right NKs being compared with the TK separately. The SM was a 1-step process combining both NKs together. The DF estimates were consistent with geometric means in both methods. Statistical evaluation included linear correlation and Bland-Altman analysis. The RM and SM showed DF of 78% ± 25% versus 79% ± 27% for the TK and 22% ± 25% versus 21% ± 27% for the NKs (P = 0.3). There was excellent correlation between SM and RM measurements (r = 0.99, P < 0.001). Bland-Altman plot demonstrated a mean difference of 1.2 ± 3.8 at a 95% confidence interval (95% CI) of agreement of -6.2 to + 8.5 for the TK and -1.2 ± 3.8 at a 95% CI of agreement of -8.5 to + 6.2 for the NKs. Only 1 (8%) of 12 scans showed a difference slightly beyond the 95% CI, indicating a good agreement between SM and RM. The SM offers a simple way to evaluate renal DF in PRTP and shows comparable results with the RM. It may have great potential in clinical practice; however, larger studies are needed to verify and further extend the results of this study.

  10. Functional control of the renal transplant via sequential computerized tomography

    1981-08-01

    The enhancement of cortex medulla and arteria iliaca can be visualized separately, evaluated densitometrically and represented graphically by means of sequential computerized tomography of the renal transplant following intravenous contrast medium bolus injection. Since this enhancement performance is mainly dependent on perfusion, it is possible to determine the perfusion value of individual measurement areas. For example, a cortical defective perfusion, as is known in rejection, becomes evident as a flattening-out of the initial rise of cortex enhancement and can be distinguished from the largely normal type of curve obtained in acute tubular necrosis (ATN). The angiographically known prolonged 'wash-out time' in rejection corresponds to a long-lasting corticomedullary density gradient. Despite restricted informative value because of the relatively small number of patients, it appears that sequential computerized tomography enables differentiation of postoperative anuria.

  11. Renalase Gene Polymorphism in Patients After Renal Allograft Transplantation

    2014-06-01

    Full Text Available Background/Aims: Renalase is a recently discovered protein, which is likely involved in regulation of blood pressure in humans and animals. Previous studies suggest that renalase reflects kidney functioning. A common missense polymorphism in the flavin-adenine dinucleotide-binding domain of human renalase (Glu37Asp has been described. In this study we examined the association between (Glu37Asp polymorphism (rs2296545 in renalase gene and kidney allograft function. Methods: The study enrolled 270 Caucasian kidney allograft recipients. SNP within the renalase was genotyped using TaqMan genotyping assays. Results: There were no statistically significant associations between renalase gene rs2296545 polymorphism and delayed graft function, acute rejection, chronic allograft dysfunction as well as creatinine serum concentrations and blood pressure values after transplantation. Conclusions: The results of this study suggest, that renalase gene rs2296545 polymorphism is not important factor determining renal allograft function.

    The goal of this study is to investigate the population pharmacokinetics of oral tacrolimus in Chinese renal transplant patients and to identify possible relationship between covariates and population parameters. Details of drug dosage history, sampling time and concentration of 802 data points in 58 patients were collected retrospectively. Before analysis, the 58 patients were randomly allocated to either the model building group (n=41) or the validation group (n=17). Population pharmacokinetic data analysis was performed using the nonlinear mixed-effects model (NONMEM) program on the model building group. The pharmacokinetics of tacrolimus was best described by a one compartment model with first-order absorption and elimination. Typical values of apparent clearance (CL/F), apparent volume of distribution (V/F) were estimated. A number of covariates including demographic index, clinical index and coadministration of other drugs were evaluated statistically for their influence on these parameters. The final population model related clearance with POD (post operative days), HCT (haematocrit), AST (aspartate aminotransferase) and coadministration of nicardipine and diltiazem. Predictive performance of the final model evaluated with the validation group showed insignificant bias between observed and model predicted concentrations. Typical value of CL/F and V/F was 21.7 L x h(-1) and 241 L, inter-patient variability (RSD) in CL/F and V/F was 41.6% and 49.7%, respectively. The residual variability (SD) between observed and model-predicted concentrations was 2.19 microg x L(-1). The population pharmacokinetic model of tacrolimus in Chinese renal transplant patients was established and significant covariates on the tacrolimus model were identified.

    Adenine phosphoribosyltransferase deficiency is a rare autosomal recessive disorder of uric acid metabolism that leads to formation and excretion of 2,8-dihydroxyadenine into urine. The low solubility of 2,8-dihydroxyadenine results in precipitation and formation of urinary crystals and renal stones. Patients with this disorder usually have recurrent nephrolithiasis and can develop nephropathy secondary to crystal precipitation in the renal parenchyma. The disease is most often underdiagnosed and can recur in renal transplant, causing graft failure. Lack of specific clinical manifestations, chemical and radiologic features identical to those shown with uric acid stones, and lack of awareness among clinicians are among the causes for the underdiagnoses of this treatable disease. Allopurinol, a xanthine dehydrogenase inhibitor, is the mainstay of treatment, supported by high fluid intake and dietary modifications. The possibility of adenine phosphoribosyl transferase deficiency should be considered in all cases of urolithiasis in children, patients with recurrent urolithiasis, and patients with urolithiasis associated with renal failure of unknown cause, including patients with end-stage renal disease and renal transplant recipients. Here, we report a case of a 41-year-old female patient who had a late diagnosis of 2,8-dihydroxyadenine nephropathy-induced end-stage renal disease, made on the native nephrectomy that accompanied the renal transplant, and who had a timely intervention that prevented recurrence in the graft.

    Opportunistic infections following immunosuppression in solid organ transplant (SOT) patients are common complications with the skin being a common sight of infection. Nontuberculous mycobacteria (NTM) are rare but potential causes of skin infection in SOT patients. We present a case of an adult male immunosuppressed following renal transplantation who presented with an asymptomatic rash for several months. The patient's skin eruption consisted of erythematous papules and plaques coalescing into an annular formation. After failure of the initial empiric therapy, a punch biopsy was performed that demonstrated nerve involvement suspicious for Mycobacterium leprae. However, culture of the biopsy specimen grew acid-fast bacilli that were subsequently identified as M. haemophilum. His rash improved after a prolonged course of clarithromycin and ciprofloxacin. Both organisms are potential causes of opportunistic skin infections and can be difficult to distinguish with similar predilection for skin and other biochemical and genetic similarities. Ultimately they can be distinguished with culture as M. haemophilum will grow in culture and M. leprae will not. This case was unique due to nerve involvement on biopsy which is classically seen on biopsies of leprosy. PMID:24369511

    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.

    Cellular transplantation may treat several human diseases by replacing damaged cells and/or providing a local source of trophic factors promoting regeneration. We utilized human renal epithelial cells (hRECs) isolated from cadaveric donors as a cell model. For efficacious implementation of hRECs for treatment of kidney diseases, we evaluated a novel encapsulation strategy for immunoisolation of hRECs and lentiviral transduction of the Green Fluorescent Protein (GFP) as model gene for genetic engineering of hRECs to secrete desired trophic factors. In specific, we determined whether encapsulation through conformal coating and/or GFP transduction of hRECs allowed preservation of cell viability and of their trophic factor secretion. To that end, we optimized cultures of hRECs and showed that aggregation in three-dimensional spheroids significantly preserved cell viability, proliferation, and trophic factor secretion. We also showed that both wild type and GFP-engineered hRECs could be efficiently encapsulated within conformal hydrogel coatings through our fluid dynamic platform and that this resulted in further improvement of cell viability and trophic factors secretion. Our findings may lay the groundwork for future therapeutics based on transplantation of genetically engineered human primary cells for treatment of diseases affecting kidneys and potentially other tissues.

    The human urinary proteome reflects systemic and inherent renal injury perturbations and can be analyzed to harness specific biomarkers for different kidney transplant injury states. 396 unique urine samples were collected contemporaneously with an allograft biopsy from 396 unique kidney transplant recipients. Centralized, blinded histology on the graft was used to classify matched urine samples into categories of acute rejection (AR), chronic allograft nephropathy (CAN), BK virus nephritis (BKVN), and stable graft (STA). Liquid chromatography–mass spectrometry (LC-MS) based proteomics using iTRAQ based discovery (n=108) and global label-free LC-MS analyses of individual samples (n=137) for quantitative proteome assessment were used in the discovery step. Selected reaction monitoring (SRM) was applied to identify and validate minimal urine protein/peptide biomarkers to accurately segregate organ injury causation and pathology on unique urine samples (n=151). A total of 958 proteins were initially quantified by iTRAQ, 87% of which were also identified among 1574 urine proteins detected in LC-MS validation. 103 urine proteins were significantly (p<0.05) perturbed in injury and enriched for humoral immunity, complement activation, and lymphocyte trafficking. A set of 131 peptides corresponding to 78 proteins were assessed by SRM for their significance in an independent sample cohort. A minimal set of 35 peptides mapping to 33 proteins, were modeled to segregate different injury groups (AUC =93% for AR, 99% for CAN, 83% for BKVN). Urinary proteome discovery and targeted validation identified urine protein fingerprints for non-invasive differentiation of kidney transplant injuries, thus opening the door for personalized immune risk assessment and therapy.

  1. Basiliximab induced non-cardiogenic pulmonary edema in two pediatric renal transplant recipients.

    We report two cases of non-cardiogenic pulmonary edema as a complication of basiliximab induction therapy in young pediatric renal transplant patients identified following a retrospective review of all pediatric renal transplant cases performed in the National Paediatric Transplant Centre, Childrens University Hospital, Temple Street, Dublin, Ireland. Twenty-eight renal transplantations, of which five were living-related (LRD) and 23 were from deceased donors (DD), were performed in 28 children between 2003 and 2006. In six cases, transplantations were pre-emptive. Immunosuppression was induced pre-operatively using a combination of basiliximab, tacrolimus and methylprednisolone in all patients. Basiliximab induction was initiated 2 h prior to surgery in all cases and, in 26 patients, basiliximab was re-administered on post-operative day 4. Two patients, one LRD and one DD, aged 6 and 11 years, respectively, developed acute non-cardiogenic pulmonary edema within 36 h of surgery. Renal dysplasia was identified as the primary etiological factor for renal failure in both cases. Both children required assisted ventilation for between 4 and 6 days. While both grafts had primary function, the DD transplant patient subsequently developed acute tubular necrosis and was eventually lost within 3 weeks due to thrombotic microangiopathy and severe acute antibody-mediated rejection despite adequate immunosuppression. Non-cardiogenic pulmonary edema is a potentially devastating post-operative complication of basiliximab induction therapy in young pediatric patients following renal transplantation. Early recognition and appropriate supportive therapy is vital for patient and, where possible, graft survival.

    Renal transplant lithiasis represents a rather uncommon complication. Even rare, it can result in significant morbidity and a devastating loss of renal function if obstruction occurs. We present our experience with graft lithiasis in our series of renal transplantations and review the literature regarding the epidemiology, pathophysiology, and current therapeutic strategies in the management of renal transplant lithiasis. In a retrospective analysis of a consecutive series of 1525 renal transplantations that were performed between January 1983 and March 2007, 7 patients were found to have allograft lithiasis. In five cases, the calculi were localized in the renal unit, and in two cases, in the ureter. A review in the English language was also performed of the Medline and PubMed databases using the keywords renal transplant lithiasis, donor-gifted lithiasis, and urological complications after kidney transplantation. Several retrospective studies regarding the incidence, etiology, as well as predisposing factors for graft lithiasis were reviewed. Data regarding the current therapeutic strategies for graft lithiasis were also evaluated, and outcomes were compared with the results of our series. Most studies report a renal transplant lithiasis incidence of 0.4% to 1%. In our series, incidence of graft lithiasis was 0.46% (n=7). Of the seven patients, three were treated via percutaneous nephrolithotripsy (PCNL); in three patients, shockwave lithotripsy (SWL) was performed; and in a single case, spontaneous passage of a urinary calculus was observed. All patients are currently stone free but still remain under close urologic surveillance. Renal transplant lithiasis requires vigilance, a high index of suspicion, prompt recognition, and management. Treatment protocols should mimic those for solitary kidneys. Minimally invasive techniques are available to remove graft calculi. Long-term follow-up is essential to determine the outcome, as well as to prevent recurrence.

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

    Renal transplant, especially from genetically related living-donors, is associated with excellent results. The security and free will of the donor are of paramount importance. A significant percentage of such transplants are not accomplished for both medical and nonmedical reasons. We looked retrospectively into the causes of nonaccomplishment of renal transplants from living-related donor transplants at our center from January 2006 through June 2008. During this period, 69 and 99 potential renal transplant recipient and donors were investigated. Transplants could be performed only in 35 patients (51%). About 59% of the donors were rejected or declined. Reasons for exclusion were immunologic in 14 donors (14%). Medical and nonmedical conditions precluded donation in 35 donors (35%) and 12 donors (12%). Medical reasons consisted mainly of undiagnosed hypertension, obesity, diabetes mellitus, and renal anomalies. In the recipients, the major reason was option for transplant tourism, occurred in 11 cases (16%). A substantial number of investigated recipients and donors for living-related transplant are not accomplished. The major reasons are medical for the donor and transplant tourism for the recipient.

    2016-06-01

    Full Text Available Introduction: Anti-HLA antibodies determination in the serum of patients on a waiting list for renal transplant is essential to optimize donor selection as well as for the induction and maintenance immunosuppression scheme, according to immunological risk. These antibodies could be present before transplantation as a result of being exposed to blood transfusions, pregnancies and previous transplants. The objective of the study was to determine immunization against HLA antigens, associated factors and their impact on the waiting list for a renal transplant. Methods: In this observational retrospective cross sectional study, 254 patients on the waiting list for renal transplant were included. These patients attended the Public Health central laboratory between July 2013 and July 2015. Results: 30% of the 254 studied patients presented anti-HLA antibodies. The most significant sensitizing event was the exposure to a previous transplant (p=<0.05. Multiparous women were in second place, 69% of them presenting positive PRA (panel reactive antibodies (p=<0.05. Finally 24% of poly transfused patients presented anti-HLA antibodies (p=<0.05. Conclusions: During the 2 year of the study, 51 patients were transplanted, presenting only one of them anti-HLA antibodies before transplantation. This results clearly indicate that the immunization against HLA represents a barrier for transplantation access.

    Renal transplant recipients are a population usually considered at a higher risk of malignancies, mostly skin cancer and lymphoproliferative disorder. In recent years, prostate cancer in renal transplant recipients has been becoming more frequent. This is probably due to the growing age and the longer survival of the transplanted patients. We report the case of a 50-year-old man with prostate cancer and renal allograft, who received radiotherapy after prostatectomy at the Institute of Radiotherapy of the University of Florence. Radiotherapy is part of the standard treatment for many cases of prostate cancer. According to the few series reported in the literature and also to our experience, radiation therapy is feasible also in renal transplant recipients with accurate treatment planning.

    Full Text Available Introduction. Aortoiliac occlusive disease and abdominal aortic aneurysm in patients with renal insufficiency on hemodialysis can significantly influence the success of renal transplantation. In the recent past, advanced atherosclerosis was considered as contraindication for renal transplantation. Complicated creation of vascular anastomoses and progression of occlusive or aneurysmal disease were the main reasons. Case report. We presented a 52-year-old man with a 5-year history of end-stage renal disease on haemodialysis. The patient was previously excluded from renal transplantation program because of severe aortoiliac atherosclerosis and abdominal aortic aneurysm. Resection of abdominal aortic aneurysm with occlusion of the iliac arteries and reconstruction with aortobifemoral synthetic grafts was performed and followed by cadaveric renal transplantation. Conclusion. Advanced atherosclerotic disease in aortoiliac segment requires elective vascular surgical reconstruction, as part of preparation for renal transplantation in patients with end-stage renal disease.

    This paper presents an e-survey of current clinical practice of use of intra-operative diuretics during renal transplantation in the United Kingdom and a study to compare outcome of renal transplants carried out with or without intra-operative diuretics in our centre. An e-mail questionnaire to renal transplant surgeons exploring their practice of renal transplantation with or without intra-operative diuretics, the type of a diuretic/s if used and the relevant doses. An observational study comparing the outcome of renal transplant recipients, group no-diuretics (GND, n = 80) carried out from 2004 to 2008 versus group diuretics (GD n = 69) renal transplant recipients who received intra-operative diuretics over a one year period is presented. Outcome measures were incidence of delayed graft function and a comparison of graft survival in both groups. Forty surgeons answered from 18 transplant centres with a response rate of 67%. 13 surgeons do not use diuretics. Mannitol is used by 10/40, Furosemide 6/40 and 11 surgeons use a combination of both. In comparative study there was no significant overall difference in one year graft survival of GD versus GND (N = 65/69, 94% and 75/80, 94% respectively, p = 0.08) and the incidence of delayed graft function was also comparable (16/69, 23% and 21/80, 26% respectively, p = 0.07). The donor characteristics in both groups were comparable. The study showed variation in clinical practice on the use of intra-operative diuretics in renal transplantation and it did not demonstrate that the use of diuretics can improve renal graft survival.

    Canada, akin to other developed nations, faces the growing challenges of end-stage renal disease (ESRD). Even with expanded donor criteria for renal transplantation (the treatment of choice for ESRD), the supply of kidneys is outpaced by the escalating demand. Remuneration for kidney donation is proscribed in Canada. Without an option of living-related transplantation (biological or emotional donors), patients often struggle with long waiting lists for deceased donor transplantation. Accordingly, many patients are now opting for more expedient avenues to obtaining a renal transplant. Through commercial organ retrieval programs, from living and deceased donors, patients are travelling outside Canada to have the procedure performed. Between September 2001 and July 2007, 10 patients (7 males, 3 females) underwent commercial renal transplantation outside Canada. We describe the clinical outcomes of these patients managed postoperatively at our single Canadian transplant centre. Six living unrelated and 4 deceased donor renal transplantations were performed on these 10 patients (mean age 49.5 years). All procedures were performed in developing countries and the postoperative complications were subsequently treated at our centre. The mean post-transplant serum creatinine was 142 μmol/L. The average follow-up time was 29.8 months (range: 3 to 73 months). One patient required a transplant nephrectomy secondary to fungemia and subsequently died. One patient had a failed transplant and has currently resumed hemodialysis. Acute rejection was seen in 5 patients with 3 of these patients requiring re-initiation of hemodialysis. Only 1 patient had an uncomplicated course after surgery. Despite the kidney trade being a milieu of corruption and commercialization, and the high risk of unconventional complications, patients returning to Canada after commercial renal transplantation are the new reality. Patients are often arriving without any documentation; therefore, timely, goal

    Discovering a new cell transplantation approach for treating chronic renal insufficiency is a goal of many nephrologists. In vitro-cultured peripheral blood mononuclear cells (PBMCs) were reprogrammed into induced mesenchymal stem cells (iMSCs) by using natural inducing agents made in our laboratory. The stem cell phenotype of the iMSCs was then identified. Unilateral ureteral obstruction (UUO) was used to create an animal model of chronic renal insufficiency characterized by renal interstitial fibrosis. The induced and non-induced PBMCs were transplanted, and the efficacy of iMSCs in treating chronic renal insufficiency was evaluated using a variety of methods. The ultimate goal was to explore the effects of iMSC transplantation on the treatment of chronic renal insufficiency, with the aim of providing a new therapeutic modality for this disease.

    Full Text Available Infections caused by commensal bacteria may be fatal for the patients under immunosuppressive therapy. This results also from difficulty in identification of high risk strains. Enterococcal infections are increasingly frequent but despite many studies on virulence traits, the difference between commensal and pathogenic strains remains unclear. Prophages are newly described as important elements in competition between strains during colonization, as well as pathogenicity of the strains. Here we evaluate a difference in presence of pp4, pp1, and pp7 prophages and ASA (aggregation substance gene expression in enterococcal isolates from renal transplant recipients (RTx with different etiology of the end-stage renal failure. Prophages sequence was screened by PCR in strains of Enterococcus faecalis isolated from urine and feces of 19 RTx hospitalized at Medical University of Gdansk and 18 healthy volunteers. FLOW-FISH method with use of linear locked nucleic acid (LNA probe was used to assess the ASA gene expression. Additionally, ability of biofilm formation was screened by crystal violet staining method. Presence of prophages was more frequent in fecal isolates from immunocompromised patients than in isolates from healthy volunteers. Additionally, both composition of prophages and ASA gene expression were related to the etiology of renal disease.

    Cardiorenal syndrome has been recently divided into 5 categories, according to acute or chronic evolution and primary organ dysfunction. Anemia can also accompany this disorder, leading to a more complex situation. This study aims to analyze the renal outcomes of patients, specifically patients with chronic Cardiorenal syndrome, with or without anemia, long-term after heart transplantation. This was a retrospective cohort study on chronic Cardiorenal syndrome patients submitted to heart transplantation. Patients were divided according to presence of anemia and renal dysfunction before heart transplantation. A total of 108 patients (92 males) with the mean age of 45±12 years were included. The etiologies of the heart failure were hypertensive dilated myocardiopathy (66%), ischemic (14%) and Chagasic (12%). Before the heart transplantation, 51 patients had an eGFR less than 60 mL/min. From these, 24 had concomitant anemia. One year after the transplantation, patients with previous isolated renal dysfunction ameliorates eGFR (45±11 vs. 65±26 mL/min, pCardiorenal syndrome presented partial renal function recovery after heart transplantation, while the presence of cardiorenal anemia was a marker of renal function non-recovery 1 year after heart transplantation.

    Full Text Available Aim: The best treatment option in relation to the advantages in survival in chronic renal disease and in life quality is renal transplantation. During or after the renal transplantation some complications may occur depending on technical reasons. In long term, various infections and metabolic disorders can appear as a result of current immunosuppressive treatments. The present study was conducted in order to determine critical conditions in management of renal transplant cases in Emergency Department and to investigate the efficacy of MODIFIED EARLY WARNING (MEW score in determining the morbidity and acute renal failure (ARF in renal transplant cases. Material and Method: 172 renal transplant recipients presenting to Uludag University Medicine Faculty Emergency Department were investigated prospectively. The patients, whose MEW scores were calculated, were evaluated in terms of the diagnoses, hospitalisation reasons, and presence of (ARF attack and the relationship with MEW score was investigated.

    Glomerular and tubular function of transplanted kidneys were assessed in 46 children aged 15.7 +/- 4.6 yr, 4.2 +/- 2.8 yr after renal transplantation. There were 34 cadaveric, and 12 living-related donors. Twelve patients (26%) had acute episodes (acute tubular necrosis, rejection, or urinary tract infection) during follow-up. All patients were on triple immunosuppression. The mean serum creatinine was 1.5 +/- 0.6 mg/dL. Creatinine clearance (Ccreat) calculated from a 24-h urine collection was 48.0 +/- 19.7 mL/min/1.73 m(2), and that estimated from the Schwartz formula, 61.0 +/- 22.5 mL/min/1.73 m(2). A positive correlation was found between the calculated and estimated clearances. Mean urine concentrating ability was 487 +/- 184 mOsmol/kg, with a value lower than 400 mOsmol/kg in 35% of patients. There was a positive correlation between urine osmolality and estimated Ccreat. Metabolic acidosis (bicarbonate <22 mmol/L) was found in 41% of patients, with relatively alkaline urine and high chloride level. Fractional excretion (FE) of sodium was above 1% in 68% of patients (mean 1.66 +/- 1.06%), and FE(Mg) was above 3% (mean 10.9 +/- 5.2%) in 93% of patients. Tubular reabsorption of phosphate (TP)/glomerular filtration rate (GFR) was 3.2 +/- 0.8 mg/dL glomerular filtrate (GF). FE(K), FE(UA), and Ca/creatinine in urine were normal. There were no functional group differences between the cadaveric and living-related kidneys. Significant group differences were found in those with acute episodes and those with a normal course. Estimated Ccreat was 54 +/- 20 vs. 67 +/- 20 mL/min/1.73 m(2) in the acute episodes and the normal course groups, respectively. Also, the FE(NA), FE(UA), and FE(Mg) were higher in the acute episodes group -2.3 +/- 1.6, 10.6 +/- 4.4, and 14.8 +/- 6.5%, respectively, compared with the normal course group -1.4 +/- 0.6, 8.2 +/- 2.8, and 9.6 +/- 4.0%, respectively. There were no between-group differences in plasma bicarbonate, FE(K), TP/GFR, and urine

    Full Text Available Suppressed mitochondrial biogenesis (MB contributes to acute kidney injury (AKI after many insults. AKI occurs frequently after liver transplantation (LT and increases mortality. This study investigated whether disrupted mitochondrial homeostasis plays a role in AKI after LT.Livers were explanted from Lewis rats and implanted after 18 h cold storage. Kidney and blood were collected 18 h after LT.In the kidney, oxidative phosphorylation (OXPHOS proteins ATP synthase-β and NADH dehydrogenase-3 decreased 44% and 81%, respectively, with marked reduction in associated mRNAs. Renal PGC-1α, the major regulator of MB, decreased 57% with lower mRNA and increased acetylation, indicating inhibited synthesis and suppressed activation. Mitochondrial transcription factor-A, which controls mtDNA replication and transcription, protein and mRNA decreased 66% and 68%, respectively, which was associated with 64% decreases in mtDNA. Mitochondrial fission proteins Drp-1 and Fis-1 and mitochondrial fusion protein mitofusin-1 all decreased markedly. In contrast, PTEN-induced putative kinase 1 and microtubule-associated protein 1A/1B-light chain 3 increased markedly after LT, indicating enhanced mitophagy. Concurrently, 18- and 13-fold increases in neutrophil gelatinase-associated lipocalin and cleaved caspase-3 occurred in renal tissue. Both serum creatinine and blood urea nitrogen increased >2 fold. Mild to moderate histological changes were observed in the kidney, including loss of brush border, vacuolization of tubular cells in the cortex, cast formation and necrosis in some proximal tubular cells. Finally, myeloperoxidase and ED-1 also increased, indicating inflammation.Suppression of MB, inhibition of mitochondrial fission/fusion and enhancement of mitophagy occur in the kidneys of recipients of liver grafts after long cold storage, which may contribute to the occurrence of AKI and increased mortality after LT.

It capacity is based on 132 censored beds and 71 no censored beds. Is considered a specialty hospital in the region of Bajío. Renal transplant program activity was initiated in 1990 and gives care for adult and pediatric population. Retrospective, comparative and longitudinal study to describe and analyze our experience. Data base and clinical charts of renal transplant recipients were reviewed. Age, gender, date of transplant, etiology of renal disease, type of donor, HLA compatibility and PRA, immunosuppressive therapy, acute rejection, serum creatinina, graft loss and mortality were registered. Statistical analysis included 2, unpaired Student T test and Kaplan-Meier survival analysis with Log Rank test. Cox Analysis was also done. 1050 renal transplants were done from November 1990 to June 2011. 50 were excluded because follow-up was not longer than 3 months. 1000 consecutive renal transplant patients from January 1995 to June 2011 were included for analysis. Patients were divided in 2 groups: group A transplanted January 1995 to December 2004; group B transplanted January 2005 to June 2011. Etiology for end stage renal disease is unknown in 61% of cases, 11% developed renal disease to diabetes mellitus. 93% patient survival was observed at median follow-up and 84.9% graft survival at median follow-up (6 years). Biopsy proven acute rejection in group A 19.9 vs. 10% in group B. Two haplotype matching shows 92% graft survival. Diabetic patients exhibit 73% graft survival vs. other as hypertension (87%). PRA >0 and serum creatinine > 2.0 mg/dL increase risk for graft loss according to Cox analysis. CONCLUSION. Results are comparable to international data. Importance of developing regional transplant centers is emphasized.

    Renal transplantation is an established treatment for end-stage renal disease. Most renal transplant patients take multiple medications for a long period of time to maintain immunosuppression as well as to treat concomitant chronic diseases. Since some medications prescribed for these patients have narrow therapeutic ranges, optimal pharmacotherapy is vital. However, pharmacists can qualify the role in assisting patients and physicians to solve and reduce drug-related problems. The purpose of this trial was to investigate the effects on treatment outcomes by clinical pharmacists joining renal transplant clinics to provide pharmaceutical care. We enrolled 37 renal transplant patients who visited the renal transplant clinic in our medical center from May 2005 through August 2006. The responsibility of the clinical pharmacist was to interview patients, review medication regimens, and make therapeutic recommendations for 3 hours every Tuesday morning. According to potential clinical impacts, pharmacist recommendations were divided into 6 scales, evaluating physician acceptance of pharmacist recommendations and impact on treatment outcomes. Fifty-five pharmacotherapy recommendations were made for the 37 renal transplant patients during the trial period, of which 81.8% were classified as clinically significant. The drug classes most commonly involved were cardiovascular medications, immunosuppressants, and antimetabolites (32.6%, 23.9%, and 26.1%, respectively). Physician acceptance rates of recommendation types and drug classes were 96.0% and 97.1%, respectively. Among the cases in which the recommendations were accepted, 94.2% of patients showed improved conditions. We concluded that clinical pharmacists joined to renal transplant clinics provide pharmaceutical care with a positive potential impact on physician prescriptions and patient outcomes.

    Scintigraphic localisation of parathyroid glands is often unsuccessful in patients with renal failure on chronic haemodialysis who have secondary hyperparathyroidism (HPT). The purpose of this study was to investigate the use of {sup 11}C-methionine PET/CT to detect hyperfunctioning parathyroid glands in patients with renal failure on chronic haemodialysis who had {sup 99m}Tc-sestamibi-negative HPT. {sup 11}C-methionine PET/CT was performed in 18 patients (11 women and 7 men, aged 42-79 years; mean age 57.8 years) on haemodialysis for renal failure (2-14 years' duration), with normo-, hypo- or hypercalcaemia and HPT not localised by either dual-tracer {sup 99m}Tc-pertechnetate/{sup 99m}Tc-sestamibi subtraction scans or dual-phase {sup 99m}Tc-sestamibi scans. In three of ten patients with normo- or hypocalcaemic HPT there was increased {sup 11}C-methionine accumulation in one gland. Seven of eight patients with hypercalcaemic HPT showed increased uptake: in five of these patients increased {sup 11}C-methionine accumulation was present in one gland, while in two it was demonstrated in two glands. All patients also had high-resolution ultrasound of the neck and were treated with subtotal parathyroidectomy, leaving a remnant of the smallest of the four glands. Regardless of their size, all glands with abnormal {sup 11}C-methionine parathyroid uptake were removed, and all demonstrated parathyroid hyperplasia. All patients developed post-parathyroidectomy hypoparathyroidism and one patient with normocalcaemic HPT relapsed 8 months after surgery. These data suggest that {sup 11}C-methionine PET/CT may be used to identify hyperfunctioning parathyroid glands in non-primary HPT, and especially hypercalcaemic HPT, when conventional {sup 99m}Tc-sestamibi imaging is non-localising.

    Full Text Available The incidence of renal cell carcinomas (RCCs in renal transplant recipients is reported as 1.1-1.5% in the native kidneys and 0.22-0.25% in the renal allograft. There are no data to support routine surveillance for tumors in transplant recipients. Most reported cases of RCCs occurring in renal allografts were incidental findings in asymptomatic patients. Herein, we report the second case of lone chromophobe RCC (ChRCC of the renal allograft presenting with weight loss. Loss of weight is a presenting symptom in one-third of ChRCCs occurring in the native kidneys in the general population. Based on the age of the patient, R.E.N.A.L nephrometry score of the tumor and the lack of data on the prognosis of this histological subtype in a climate of long-term immunosuppression, we elected for radical nephrectomy. We suggest that RCCs should be considered in the differential diagnosis of a transplant recipient presenting with weight loss even in the absence of localizing symptoms or signs.

    To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

    Renal transplantation is the method of choice for renal replacement therapy in the majority of patients. Immunosuppressive drugs may increase the risk of developing malignancies. We present a case of a patient having undergone different renal replacement methods over 25 years. He had good graft function at 12 years of transplantation. Development of spontaneous retroperitoneal hematoma caused by rupture of the native kidney oncocytoma was complicated with sepsis and deterioration of graft function. We emphasize the importance of regular ultrasonography follow-up of native kidney, which is challenging because of fibrous changes.

    Despite the significant morbidity associated with renal failure after lung transplantation (LTx), no predictive models currently exist. Accordingly, the purpose of this study was to develop a preoperative risk score based on recipient-, donor-, and transplant-specific characteristics to predict postoperative acute renal failure in candidates for transplantation. The United Network of Organ Sharing (UNOS) database was queried for adult patients (≥ 18 years of age) undergoing LTx between 2005 and 2012. The population was randomly divided into derivation (80%) and validation (20%) cohorts. The primary outcome of interest was new-onset renal failure. Variables predictive of acute renal failure (exploratory p value renal failure to construct the risk stratification score (RSS). During the study period, 10,963 patients underwent lung transplantation, and the incidence of renal failure was 5.5% (598 patients). Baseline recipient-, donor-, and transplant-related factors were similar between the cohorts. Eighteen covariates were included in the multivariable model, and 10 were assigned values based on their relative odds ratios (ORs). Scores were stratified into 3 groups, with an observed rate of acute renal failure of 3.1%, 5.3%, and 15.6% in the low-, moderate-, and high-risk groups, respectively. The incidence of renal failure was found to be significantly increased in the highest risk group (p renal failure highly correlated with actual rates observed in the population (r = 0.86). We introduce a novel and simple RSS that is highly predictive of renal failure after LTx. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    Summary Background and objectives Acidosis is prevalent among renal transplant recipients (RTRs) and adversely affects cardiometabolic processes. Factors contributing to acidosis are graft dysfunction and immunosuppressive drugs. Little is known about the potential influence of diet on acidosis in RTRs. This study examined the association of metabolic acid load with acidosis and with cardiovascular risk factors in RTRs and aimed to identify dietary factors associated with acidosis. Design, participants, setting, & measurements 707 RTRs were included. Metabolic acid load was assessed by measuring 24-hour urinary net acid excretion (NAE; i.e., titratable acid + ammonium − bicarbonate). Acidosis was defined as serum [HCO3−] acidosis and between dietary factors and acidosis. Results Mean age ± SD was 53±13 years; 57% of patients were male. Acidosis was present in 31% of RTRs. NAE was associated with acidosis (serum HCO3−: β=−0.61; serum pH: β=−0.010; both Pacidosis, diet might influence acid-base homeostasis in RTRs. Higher intake of fruits and vegetables and lower animal protein intake is associated with less acidosis in RTRs. PMID:22935845

    Full Text Available We have determined the number of circulating T, B and natural killer cells in renal transplant recipients in order to detect changes during cytomegalovirus (CMV infections. Serial blood samples were taken from 61 patients on standard triple immunosuppression therapy (cyclosporin A, azathioprine and prednisone. Using two-color flow cytometry analysis, the absolute number of CD3+, CD4+, CD8+, CD19+, CD3+HLA-DR+ and CD16+56+ cells was determined. Forty-eight patients (78.7% developed active CMV infection, and all of them subsequently recovered. Twenty of the infected patients (32.8% presented symptoms compatible with CMV disease during the infectious process. The number of lymphocytes and their main subpopulations were normal before the onset of CMV disease. During the disease there was a decrease followed by a significant increase (P<0.005 in the number of CD3+, CD4+, CD8+ and CD3+HLA-DR+ cells. No significant changes were observed in natural killer cells or B lymphocytes during the disease. We conclude, as observed in all viremic patients recovering from infection, that recovery is associated with an increase in the number of T cell subsets. The monitoring of different lymphocyte subsets along with antigenemia can be extremely useful in the detection of patients at high risk of developing CMV symptoms, allowing the early introduction of antiviral therapy or the reduction of immunosuppression therapy.

    The aim of this study was to identify acute renal injury (ARI) through the use of RIFLE (risk, injury, failure, loss, end-stage kidney disease) criteria and to investigate perioperative risk factors for ARI in liver transplantation (LT). We reviewed medical records of adult LT patients retrospectively. Postoperative ARI was staged with RIFLE criteria by the 1st and 7th days of the surgery. We analyzed 440 adult LT patients, categorized as risk (R), injury (I), or failure (F) according to the RIFLE criteria. In this study, in the first postoperative day, incidence of ARI was 7.95%; all of them were R-class, and, on the 7th day, the incidence of ARI was 7.27%, as R-class 6.59% and I-class 0.68%. Significant risk factors were detected within the first postoperative day including pre-operative hemoglobin levels 20) (P = .002). This study showed that RBC and FFP transfusion, perioperative blood loss, and MELD score >20 are risk factors for LT-related ARI. Also normalization of hemoglobin levels with non-blood products in patients with preoperative low hemoglobin levels can diminish the need for RBC and that can prevent ARI.

    Dengue fever in renal transplanted patients has not been studied well, and we review all the literature about episodes dengue fever in renal transplant patients. The aim was to describe clinico-pathological characteristics, immunosuppressive protocols, need renal outcome and mortality. PubMed, LILACS, Google Scholar and Research Gate were searched for "Dengue" and "Renal/Kidney Transplantation" with no date limits. Hits were analyzed by two researchers separately. Fever, myalgia, arthralgia and headache was significantly lower than normal population, while pleural effusions and ascites were observed more. Incidence of severe dengue is significantly higher among transplant patients in this review, as well as they had a significantly higher mortality (8.9% vs 3.7%, p = 0.031). Age, period after transplantation and immunosuppressive profile had no effect on disease severity, mortality or graft out come. Presence of new bleeding complications and ascites was associated with more severe disease (p dengue fever in renal transplanted patients differ from the general population. Some degree of graft dysfunction is common during the illness, but only a minority develops graft failure.

  11. Percutaneous Fixation of Anterior Column Acetabular Fracture in a Renal Transplant Recipient

    Full Text Available Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. 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.

    The frecuency of malignancies in renal transplant (RT) patients is increasing. Renal cell carcinoma (RCC) of native kidneys is one of the most frequent and its outcome can be more aggressive than in general population. To evaluate the incidence and prognosis of RCC in renal transplant patients followed in our transplantation unit. Between January 1997 and December 2009, 683 patients underwent kidney transplant at our hospital. Ultrasonography of the native kidneys was annually performed in all renal transplant patients. When suspect solid masses were found at ultrasonography, patients underwent computed tomography. If the suspicion was confirmed, nephrectomy was performed. 14 radical nephrectomies were performed in 12 patients due to suspect CCR. In 11 nephrectomies (corresponding to 9 patients), anatomopathologic diagnosis was CCR (incidence 1.5%). Histologic stage was T1N0M0 in all cases. In the other 3 RT, the diagnosis was complicated renal cyst. Those patients without carcinoma had polycystic kidney disease. The time on dialysis before CCR diagnosis was 36.7 ± 24.3 months and the interval between RT and diagnosis was 39 ± 25.8 months. After a mean follow-up of 58.6 ± 38.6 months, the outcome of all cases has been excellent, without tumor recurrence. Annual renal ultrasonography plays a key role in the early diagnosis of CRR. The early treatment of this pathology is associated with an excellent prognosis in RT patients.

    Full Text Available Outpatient parenteral antimicrobial therapy (OPAT is a well-established method in medical specialties. Its use in renal transplant recipients has not been thoroughly explored. No guidelines within this patient subset exist. This study describes OPAT outcomes within a UK teaching hospital renal transplant population. Renal function, mapped by estimated glomerular filtration rate (eGFR, and clinical response to infection were collected retrospectively. A total of 635 antimicrobial episodes were administered to nine renal transplant patients over 12 discrete OPAT courses during the study period. Eleven of 12 OPAT courses (91.67% produced a clinical improvement in infection. One course was terminated due to immunosuppressive-related neutropenia. No patient required admission due to failure of OPAT or adverse events. There was no significant change in graft function throughout the OPAT courses compared with baseline renal function (ANOVA, P = 0.06. One minor line infection was reported. This was treated conservatively and did not interrupt the OPAT. OPAT is safe and clinically effective in our renal transplant recipients with no significant deterioration in eGFR. The incidence of adverse events, specifically line complications, was lower in our population than those reported in the literature. Future work should develop OPAT guidelines designed for transplant recipients to outline the degree of monitoring required.

    Full Text Available Abstract Background Renal allograft recipients are reported to have a higher incidence of malignancy than the general population. This single hospital-based study examined the incidence and clinicopathologic behavior of uterine cervical carcinoma in renal transplant recipients. Methods Among 453 women receiving renal transplantation from January 1990 to December 2008, 5 patients were diagnosed with cervical carcinoma. Medical records of these 5 patients were retrospectively reviewed, and clinicopathologic data were collected and analyzed. Results The incidence of cervical carcinoma in renal transplant recipients was 58.1 out of 100,000 per year, which is 3.5 times higher than in the general Korean population. The mean interval between the time of renal transplantation and the time of cervical carcinoma diagnosis was 80.7 months. After a median follow-up of 96.2 months, there was no recurrence of the disease or death. In 4 patients who were positive from human papillomavirus in situ hybridization (HPV ISH, high or probably high risk HPV DNA was detected in all. Punctate staining of HPV ISH was detected in 3 out of 4 patients. Conclusions Higher incidence of cervical carcinoma is expected in renal transplant recipients, so appropriate surveillance is needed to ensure early detection and treatment of cervical carcinoma.

    Sirolimus and tacrolimus are the major immunosuppressants for renal transplantation. Several studies have compared these 2 drugs, but the outcomes were not consistent. The aim of this study was to evaluate the efficacy, safety, and pharmacoeconomics of sirolimus and tacrolimus in the treatment of renal transplantation and provide evidence for the selection of essential drugs. Trials were identified through a computerized literature search of PubMed, EMBASE, Cochrane controlled trials register, Cochrane Renal Group Specialized Register of randomized controlled trials, and Chinese Biomedical database. Two independent reviewers assessed trials for eligibility and quality and then extracted data. Data were extracted for patient and graft mortality, acute rejection (AR), and adverse events. Dichotomous outcomes were reported as relative risk with 95% confidence intervals. A decision tree model was populated with data from a literature review and used to estimate costs and QALYs gained and incremental cost-effectiveness. Altogether, 1189 patients from 8 randomized controlled trials were included. The results of our analysis were that tacrolimus reduced the risks after renal transplantation of AR and patient withdrawn. Nevertheless, tacrolimus increased the risk of infection. Pharmacoeconomic analysis showed that tacrolimus represented a more cost-effective treatment than does cyclosporine for the prevention of adverse events after renal transplant. Tacrolimus is an effective and safe immunosuppressive agent, and it may be more cost-effective than cyclosporine for the primary prevention of AR in renal transplant recipients. However, it should be noted that such superiority was reversal when the cost of sirolimus and tacrolimus changed.

    2009-06-04

    BACKGROUND: Renal transplantation remains the preferred method of renal replacement therapy in terms of patient survival, quality of life and cost. However, patients have a high risk of complications ranging from rejection episodes, infection and cancer, amongst others. AIMS AND METHODS: In this study, we sought to determine the long-term health outcomes and preventive health measures undertaken for the 1,536 living renal transplant patients in Ireland using a self-reported questionnaire. Outcomes were divided into categories, namely, general health information, allograft-related information, immunosuppression-related complications and preventive health measures. RESULTS: The results demonstrate a high rate of cardiovascular, neoplastic and infectious complications in our transplant patients. Moreover, preventive health measures are often not undertaken by patients and lifestyle choices can be poor. CONCLUSIONS: This study highlights the work needed by the transplantation community to improve patient education, adjust immunosuppression where necessary and aggressively manage patient risk factors.

    Renal transplant is one of the best ways to extend life of patients in the end stage of renal disease. Infections are significant causes of morbidity and mortality after renal transplant. The aim of this study was to evaluate frequency, risk factors, causative pathogens, and clinical manifestations in renal transplant recipients from Mashhad City during the first year after transplant. This research was conducted at Montaserie Hospital of Mashhad University of Medical Sciences from March 2013 to July 2015. All studied cases were followed for 1 year. In this retrospective study, our study cohort comprised 193 kidney transplant recipients, including 118 male (61.1%) and 75 female (38.9%) patients, with mean age of 34.4 ± 12.2 years. Of the total patients, 58 received kidneys from living donors (30.1%) and 135 received kidneys from deceased donors (69.9%). We found that 151 infectious episodes had occurred in 96 patients. The most common infectious site involved the urinary tract (39.1%). Escherichia coli was the most frequently isolated pathogen. The only significant infection risk factor to affect transplant outcomes during the first year was age. Infections are highly prevalent during the first year after transplant. Prevention and effective antibiotic therapy can reduce the related adverse effects.

    The objective of this study was to explore the donor and recipient factors related to the spectral Doppler parameters of the transplant kidney in the early posttransplantation period. This retrospective study included 76 patients who underwent renal transplantation assessed using Doppler ultrasonography (US) on the first postoperative day. We compared spectral Doppler parameters (peak systolic velocity [PSV] and resistive index [RI]) of the segmental artery of the transplant kidney according to the type of renal transplant, level of serum creatinine (SCr) of donor prior to organ donation, and donor/recipient age. RI was significantly higher in deceased-donor kidney transplantation (DDKT) as compared with living-donor kidney transplantation (LDKT; 0.73 ± 0.10 vs 0.66 ± 0.11; P = .007). In the DDKT recipients, multivariate analysis showed donor SCr was the only factor affecting PSV (P = .023), whereas recipient age was the only factor affecting RI (P = .035). In the LDKT recipients, multivariate analysis showed recipient age was the only factor affecting both PSV (P = .009) and RI (P = .018). Spectral Doppler parameters in the early posttransplantation period are related to the type of renal transplant, donor renal function, and recipient age. These factors should be taken into consideration when interpreting the results of spectral Doppler US. Copyright © 2012 Elsevier Inc. All rights reserved.

  19. The challenge of doing what is right in renal transplantation: balancing equity and utility.

    Science.gov (United States)

    Courtney, Aisling E; Maxwell, Alexander P

    2009-01-01

    Arguably the greatest challenge faced by the transplant community is the disparity between the number of persons waiting for a solid organ transplant and the finite supply of donor organs. For renal transplantation the gap between supply and demand has risen annually reflecting the increasing prevalence of end-stage renal disease versus the relatively static deceased donor organ pool. Maximising the benefit from this scarce resource raises difficult ethical issues. For most patients on dialysis therapy a successful transplant offers improved quality and quantity of life, but the absolute gain in survival provided by a donated organ varies greatly depending on recipient factors such as age and co-morbid illnesses. The philosophies of equity (a fair opportunity for everyone in need to receive a transplant) and utility (optimal profit from each organ) are often competing. National allocation schemes and local policies regarding assessment of potential recipients and acceptance of organs are designed to balance these ethical principles in a standardized and socially acceptable manner. The ongoing debate surrounding these issues and modifications to such policies reflect the evolving clinical picture of renal transplantation and the challenge in maintaining equipoise between renal transplant utility and equity.

    Shrestha, Badri Man

    2017-02-01

    Tacrolimus, a calcineurin inhibitor, has been the cornerstone of immunosuppressive regimens in renal transplant over 2 decades. This has significantly improved the outcomes of renal transplant, including reduction of acute rejection episodes, improvement of renal function and graft survival, and reduction of some of the adverse effects associated with cyclosporine. However, use of tacrolimus is associated with a number of undesirable effects, such as nephrotoxicity, posttransplant diabetes mellitus, neurotoxicity, and cosmetic and electrolyte disturbances. To alleviate these effects, several strategies have been adopted to minimize or eliminate tacrolimus from maintenance regimens of immunosuppression, with some success. This review focuses on advancements in the understanding of the basic science related to tacrolimus and the clinical evidences that have examined the efficacy and safety of tacrolimus in renal transplant over the past 2 decades and highlights the future directions.

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

    Full Text Available Introduction.We analyzed the clinical case of a 51 years old man, kidney transplanted on December 2002. On April 2011, he had acute rectal bleeding, renal chronic rejection (creatinine 2.9 mg/dl, Hgb 8.7 g/dl, positive anti-CMV antibodies (IgG. A colonoscopy showed diverticulosis of the rectum associated with deepithelialisation. The patient was treated with maintenance immunosuppressive post-transplant therapy. On June 2011, the colonoscopy showed a stenosing lesion of the sigmoid colon, and blood sampling and intestinal biopsy were performed to search Cytomegalovirus (CMV DNA by PCR. Methods. The presence of CMV-DNA was sought by automatic extractor QIACUBE, using QIAamp DNA BLOOD Mini Kit (Qiagen for whole blood and QIAamp DNA Mini Kit (Qiagen for biopsy.The extracted DNA was then amplified by Real Time PCR using Q-CMV RealTime Complete Kit (Nanogen, on instrument Applied Biosystems 7300. Results. At disease onset the viral load in whole blood was 208000 Geq/ml, and biopsy was positive. Antiviral therapy with Ganciclovir led to the negativity of the viral load and remission of symptoms. Conclusions. The clinical case described presented a reactivation of CMV infection in the intestine after more than 10 years from kidney transplantation, while the highest incidence of CMV reactivation usually occurs during the first year. In our opinion, the reactivation can be traced to long-term immunosuppressive therapy (maintenance posttransplant therapy in combination with a state of inflammation of the intestinal mucosa. In fact, patients with IBD treated with steroid drugs, in particular the group of refractory to therapy and thus have a recovery of the inflammatory process, are exposed to reactivation of CMV with intestinal localization.

    Retrospective studies suggest that donor desmopressin (DDAVP) treatment improves renal transplant outcome. The present study tests the hypothesis that desmopressin neutralizes the graft's endothelium from proinflammatory angiopoietin 2 containing Weibel-Palade bodies in the donor, resulting in reduced Weibel-Palade body release at the time of reperfusion in the recipient. Using rat models, we examined the influence of desmopressin treatment on the expression of vasopressin 2 receptors and adhesion molecules in brain-dead donors, with renal function examined in allogeneic recipients. The influence of desmopressin on the expression of adhesion molecules also was tested in vitro. Vasopressin 2 receptors were restricted to collecting ducts and distal tubules and only scarcely found in the renal vasculature. Vasopressin 2 receptor expression was down-regulated in brain-dead rats by desmopressin. Renal expression of vascular cellular adhesion molecule 1 and intercellular adhesion molecule 1 were significantly reduced in these rats. In contrast, angiopoietin 2 did not influence the expression of adhesion molecules in in vitro cultured endothelial cells after tumor necrosis factor ? stimulation. Donor desmopressin treatment improved neither renal function nor histology in allogeneic renal transplant recipients. Our data do not support the hypothesis that the clinically observed salutary effect of desmopressin is mediated by depletion of Weibel-Palade bodies in renal allografts.

    Renal dysfunction of acute liver failure (ALF) may have distinct pathophysiological mechanisms to hepatorenal syndrome of cirrhosis. Yet, the impact of perioperative renal function on posttransplant renal outcomes in ALF patients specifically has not been established. The aims of this study were (1) to describe the incidence and risk factors for chronic renal dysfunction following liver transplantation for ALF and (2) to compare renal outcomes with age-sex-matched patients transplanted for chronic liver disease. This was a single-center study of 101 patients transplanted for ALF. Fifty-three-and-a-half percent had pretransplant acute kidney injury and 64.9% required perioperative renal replacement therapy. After transplantation the 5-year cumulative incidence of chronic kidney disease (eGFR kidney injury (p = 0.288) or renal replacement therapy (p = 0.134) and chronic kidney disease. Instead, the independent predictors of chronic kidney disease were older age (p = 0.019), female gender (p = 0.049), hypertension (p = 0.031), cyclosporine (p = 0.027) and nonacetaminophen-induced ALF (p = 0.039). Despite marked differences in the perioperative clinical condition and survival of patients transplanted for ALF and chronic liver disease, renal outcomes were the same. In conclusion, in patients transplanted for ALF the severity of perioperative renal injury does not predict posttransplant chronic renal dysfunction. © 2011 The Authors Journal compilation © 2011 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Renal transplant recipients (RTR) are often advised to refrain from alcohol because of possible interaction with their immunosuppressive medication. Although moderate alcohol consumption is associated with reduced risk of diabetes and mortality in the general population, this is unknown for RTR.

    To report the incidence, etiology, and treatments of diabetes insipidus-like state that complicate percutaneous transluminal renal stenting (PTRS) for transplant renal artery stenosis (TRAS). Data from 7 patients on whom PTRS for TRAS was performed between October 2008 and March 2012 were reviewed retrospectively. The parameters investigated included blood flow velocity, blood pressure, and creatinine levels before and after the intervention. The procedural success rate was 100%. Three cases developed a diabetes insipidus-like state in the immediate postprocedural period. Urine output returned to normal within 2 weeks after treatment. The median blood flow velocity was significantly reduced from 4.51 m/sec (4.31-4.61 m/sec) at the time of TRAS diagnosis to 1.33 m/sec (1.31-1.51 m/sec) at the most recent follow-up of the group with a diabetes insipidus-like state. The ratio of median blood flow velocity before and after stenting in the group with a diabetes insipidus-like state was significantly higher than that in the group without a diabetes insipidus-like state (3.39 vs. 1.93). Diabetes insipidus-like state that complicates PTRS for TRAS is not an uncommon event, but appears to be underreported in the medical literature. A high ratio of pre- and poststenting median blood flow velocity may be a predictor for a postprocedural diabetes insipidus-like state. The most probable cause may be the marked increase in renal arterial flow. Early recognition of the condition is essential to avoid dehydration and electrolyte imbalance.

    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 urinary tract infection among our renal transplant patients. However, recurrence did not adversely affect graft or patient survival.

    The organized nephrological care in Szombathely commenced its activities in 1976. Follow-up of our patients who has undergone a kidney transplantation. We used the local and national databases. 213 patients (7 preemptive, 206 dialyzed) had 240 renal transplantations. Only 11 of them were living organ donation. Between 69 transplantations (Tx) were carried out between 1976-1995, and 163 Tx were done in the second 20 years. 122 patients (57%) are still alive (the average survival of these patients in renal replacement therapy - RRT - are 11.4 years), and 7 of them had transplantation between 1976-1995. The longest survival time was 35.1 years. Prevalence of patients on RRT at the end of 2016 was 1367 pmp in our county (32.5% living with functioning graft). Number of transplanted patients has grown in the last decade. Proportion of living organ donation was minimal. Orv Hetil. 2017; 158(25): 984-991.

    Objective: Studies evaluating renal transplant (RT) outcome in children who underwent an augmentation cystoplasty (AC) are contradictory and the current knowledge is based on studies with a limited number of patients. The aim of this study is to compare RT outcome between children who underwent AC and those without augmentation. Patients and methods: A total of 20p who underwent an AC prior to the RT (12 with ureter and 8 with intestine) were enrolled in the study and were compared to a control group of 24p without AC, transplanted in the same time period (1991–2011). Data including; age at transplant, allograft source, urological complications, urinary tract infections (UTI) incidence, the presence of VUR, and patient and graft survival were compared between the groups. Results: Mean age at RT and mean follow-up were 9.7 vs. 7.9 years and 6.9 vs. 7.9 years in the AC group and control group, respectively (NS). The graft originated in living donors for 60% of AC patients and 41.6% of the control RT patients. The rate of UTI were 0.01 UTI/patient/year and 0.004 UTI/patient/year in the augmented group and controls, respectively (p = 0.0001). In the AC group of 14p with UTIs, 10 (71%) had VUR and 5p out of 8 (62.5%) in the control group had VUR. In the AC group, of the 7p with ≥3 UTIs, 3 (43%) were non-compliant with CIC and the incidence of UTIs was not related with the type of AC or if the patient did CIC through a Mitrofanoff conduit or through the urethra. Graft function at the end of study was 92.9 ± 36.85 ml/min/m2 in the AC group and 88.17 ± 28.2 ml/min/m2 in the control group (NS). Graft survival at 10 years was also similar 88% in the AC group and 84.8% in controls. In the AC group 3p lost their grafts and 5 in the control group with respective mean follow-up of 10.6 ± 4.3 and 7.1 + 4.7 years. Conclusion: There are no significant differences in the RT outcome between children transplanted with AC or without. However

    Full Text Available We report a 52-year-old male with no family history of colonic cancer, who was found to have advanced colonic cancer with metastases two months post renal transplantation. With this case, we highlight the possibility of acute fulminant cancer metastases within short period after renal transplantation and the importance of periodic colorectal cancer screening pre-transplant. To our knowledge, this case is not yet reported in the literature, especially with such presentation of acute fulminant colonic cancer metastases post renal transplantation.

    Full Text Available Purpose: To assess the effects of transplant renal artery stenosis (TRAS on blood pressure, renal function, and graft survival. To assess the usefulness of Doppler in predicting the clinical significance of TRAS and also to identify the predictive factors in Doppler that correlated with clinical features of TRAS. Materials and Methods: A prospective study was done on consecutive renal allograft recipients at Christian Medical College, over a period of 66 months from January 2002. All recipients underwent Doppler ultrasound (DUS evaluation on the fifth post-operative day. Subsequent evaluation was done if the patients had any clinical or biochemical suspicion of TRAS. Angiogram was done in case of a high index of suspicion of significant stenosis or before angioplasty and stenting. The clinical and radiological outcomes of the patients with symptomatic or asymptomatic TRAS were analyzed. Results: Five hundred and forty three consecutive renal allograft recipients were analyzed, of whom, 43 were found to have TRAS. Nine recipients (21% were detected to have TRAS on first evaluation. All had a high peak systolic velocities (PSV recorded while 25 of them had other associated features. Patients with only high PSV required no further intervention and were followed up. They had a pretransplant mean arterial pressure (MAP of 107.83 mmHg (SD = 13.32, ranging from 90 to 133 mm Hg and a posttransplant MAP of 106.56 mmHg (SD =16.51, ranging from 83 to 150 mm Hg. Their mean nadir serum creatinine was 1.16 mg% (SD = 0.24, at detection was 1.6 mg% (SD = 1.84 and at 6 months follow-up was 1.26 mg% (SD=0.52. Of the remaining 25 patients with other associated Doppler abnormalities, 11 required further intervention in the form of re-exploration in 2, angioplasty in 3 and stenting in 6 patients. One patient in the group of patients intervened, expired in the immediate post-operative period due to overwhelming urosepsis and consumption coagulopathy. The mean

    Successful organ transplantation relies on several ancillary activities such as the identification of a compatible donor, organ allocation and procurement and the coordination of the transplant process. No existing study of the overall costs, in France, of these additional transplantation activities could be identified. This study determines the total additional costs of ancillary transplantation activities by comparing the costs of kidney transplantations with living donors against those using deceased donors. The data used are drawn from the 2013 public healthcare tariff calculations, PMSI recorded activity and transplant activity in 2012 as assessed and reported by the Agence de la biomédecine. The results show that, in 2012, additional transplant costs varied from 13835.44 € to 20050.67 € for a deceased donor and were 13601.66 € for a living donor. In conclusion, this study demonstrates that all the costs covered by National Health Insurance need to be taken into account in the economic impact evaluation of renal transplantation and during the development of this national priority activity.

    Full Text Available Potential donors with congenital renal anomalies but normal renal function are often overlooked because of a possible increase in technical difficulty and complications associated with the surgery. However, as the waiting list for a deceased donor kidney transplant continues to grow, it is important to consider these kidneys for potential transplant. This paper describes the procurement of a crossed fused ectopic kidney, and subsequent parenchymal transection prior to transplantation as part of a combined simultaneous kidney pancreas transplant. The transplant was uncomplicated, and the graft had immediate function. The patient is now two years from transplant with excellent function.

    Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia. Postoperative laboratory studies indicated a decreased level of iPTH. A positron emission tomography-computed tomography performed 6 months after the operation revealed no evidence of local recurrence or distant metastasis. Copyright © 2013.

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

    Infections are a major cause of morbidity and mortality after renal transplantation. However, data focusing on children are scarce. The objective of this study was to investigate the frequency and predictors of bacterial infection in pediatric renal transplant recipients in a specific setting of hospitalization due to fever. Clinical and laboratory data were retrospectively collected for all pediatric renal transplant recipients hospitalized for fever in a national renal transplantation center from 2004 to 2012. One hundred and sixty-eight hospital admissions for fever of 52 children were analyzed. A bacterial etiology was diagnosed in 85 admissions (50.6%); 49 cases (57.6%) were documented microbiologically and 36 (42.4%) clinically. Risk factors and markers of bacterial infection included older age, presence of a central venous catheter, sonographic findings, and elevated inflammatory indices. C-reactive protein level was a more sensitive marker than white blood cell count and absolute neutrophil count. In patients without identified risk factors, no bacterial infections were diagnosed. Pediatric renal transplant recipients hospitalized for fever are at high risk of bacterial infections and usually require empirical antibiotic treatment at admission. However, there is a minority of low-risk patients in whom clinicians may consider withholding antibiotic treatment with close follow-up. © 2017 John Wiley & Sons A/S.

    The current success of cardiac transplantation is in part attributable to the development of effective immunosuppressive agents such as cyclosporine. However, concern remains regarding the potential for cyclosporine-induced nephrotoxicity. Animal studies and early reports of renal protective effects of pentoxifylline in bone marrow transplant recipients prompted a randomized trial in cardiac transplant recipients. Twenty-nine patients were randomized to receive pentoxifylline 400 mg p.o. t.i.d. or matching placebo for 1 year after cardiac transplantation. Renal function was assessed preoperatively and at 1, 6, and 12 months postoperatively. Glomerular filtration rate and renal plasma flow were measured with iothalamate and para-aminohippurate, respectively. Serum creatinine was also measured. Ambulatory blood pressure monitoring after withdrawal of antihypertensives for 3 days was performed 12 months postoperatively. Twenty-seven patients completed the study. Glomerular filtration rate rose between 1 and 6 months after transplantation, presumably due to the reduction in goal cyclosporine level in that period, and then fell modestly between 6 and 12 months, presumably due to ongoing nephrotoxic effects of cyclosporine. No difference in glomerular filtration rate or creatinine was seen between pentoxifylline and placebo groups at any interval. Renal plasma flow increased modestly between baseline and 6 months in the pentoxifylline group, but not in the placebo group, and then fell between 6 and 12 months. Serum creatinine increased between baseline and 6 months in both groups, apparently due to increased body weight. Results of 18-hr ambulatory blood pressure monitoring obtained 1 year after transplantation was not different between groups. Renal function declines only modestly in the first year after cardiac transplantation. Pentoxifylline did not attenuate this process and had no effect on blood pressure. The modest decline in renal function may be related to

    Daily hemodialysis improves patients' quality of life and blood purification, but its effect on survival remains controversial. The aim of this study was to analyze the association between daily hemodialysis and renal transplantation and survival in France. This was an observational cohort study based on the French REIN registry. All incident patients ≥18 y/o who started daily hemodialysis in France between 2003 and 2012 were included. Using a propensity score, 575 patients on daily hemodialysis were matched with 1696 patients receiving thrice-weekly hemodialysis. Survival analysis was performed using the Cox model. Access to the renal transplant waiting list and renal transplantation were analyzed using the Fine and Gray model. Daily hemodialysis was not independently associated with reduced access to transplant waiting list, whereas, major comorbidities remained associated with restricted waitlisting after multivariate analysis adjusted for confounding factors. After being waitlisted, the cumulative incidence of renal transplantation was lower for the daily hemodialysis than for the thrice-weekly hemodialysis group (SHR = 0.72, 95%CI: 0.56-0.91). The risk of death was significantly higher in the daily hemodialysis group (HRadjusted  = 1.58, 95%CI: 1.4-1.8). Major comorbidities were associated with higher risk of death and lower likelihood of receiving a renal transplant during the follow-up period. Our study showed that in France, the likelihood of undergoing renal transplantation after being waitlisted was lower for patients on daily hemodialysis than those on thrice-weekly hemodialysis. Moreover, daily hemodialysis was associated with higher risk of death, even after taking into account age and all major comorbidities. This article is protected by copyright. All rights reserved.

    To determine the influence of pill burden and drug cost on outcomes after renal transplantation. Retrospective medical record review. Kidney and pancreas transplantation center. Sixty-eight adults who underwent kidney or kidney-pancreas transplantation during 2007. The median pretransplantation pill burden was 15 pills/day, which increased to 25 pills/day at 1 month after transplantation and returned to 16 pills/day by 1 year after transplantation. Pretransplantation pill burden was lower than the burden at 1, 3, 6, 12, and 24 months after transplantation (pafter transplantation ($2564/mo, p=0.04) but was similar thereafter. Higher pretransplantation pill burden was associated with increased serum creatinine concentration at 6 months after transplantation (r=0.288, p=0.017). Higher pill burdens at 1 month (r=0.364, p=0.002), 3 months (r=0.332, p=0.006), and 6 months (r=0.374, p=0.002) were associated with increased 3-month serum creatinine concentration. Higher drug costs were associated with increased serum creatinine concentrations throughout the study. Higher pretransplantation pill burden and higher drug cost may be associated with poor renal function after transplantation. Further study addressing factors associated with nonadherence is needed. © 2012 Pharmacotherapy Publications, Inc.

    The incidence and treatment of prostate cancer in male renal-transplant patients has not been extensively evaluated. With the aging of the renal-transplant population, the diagnosis and management of prostate cancer in these patients needs further evaluation. In this study, we conducted a retrospective review of data from 498 male renal-transplant patients to evaluate the prevalence, treatment, and outcome of prostate cancer in this population. Of the 498 male renal-transplant patients, nine were diagnosed with prostate cancer. A prostate specific antigen (PSA) screening program was not utilized, and these patients were diagnosed based on a prostate digital rectal examination and/or elevated PSA. The median age at transplantation was 55 years, and the median age at the diagnosis of prostate cancer was 63.6 years. One patient was treated with androgen ablation alone, four patients were with radiation alone, and four patients were treated with a combination of androgen ablation and external radiation. Twelve skin malignancies occurred in five of the patients with prostate cancer. Our patient population was preferentially treated with radiation therapy rather than radical prostatectomy. Seven of these treated patients are currently being followed and have good control of the disease. Two of the seven patients are on dialysis because of chronic allograft nephropathy. One patient was lost to follow-up, and one died with extensive metastasis, paraplegia, and renal failure. The incidence of diagnosed prostate cancer in patients with renal transplant will increase because of systematic PSA screening. The recommended current treatment modality depends on the Gleason grade, stage, PSA levels, and associated comorbid conditions. A combination of radiation treatment with androgen ablation provides good control of the disease while preserving renal function.

    To define the pharmacokinetic profile of the induction dose of propofol in chronic renal failure patients. Determination of propofol blood concentrations after the bolus dose of 2 mg.kg-1 bw injected in 30 seconds in a peripheral vein in a group of chronic renal failure (CRF) patients and in a group of normal patients (controls). 10 CRF patients (7 males, 3 females, mean age 47 +/- 8 years old, mean body weight 66 +/- 8 kg) candidates to cadaveric renal transplantation and free from major hepatic diseases (study group); 8 ASA I patients (5 males, 3 females), without major cardiorespiratory, hepatic, renal, hematologic or metabolic diseases undergoing minor elective surgical procedures lasting from 50 to 90 minutes (control group). a) propofol blood concentrations by means of HPLC; b) derived pharmacokinetic parameters (calculated by means of Siphar, version 4.0, Societé de informatique médicale, Simed, Paris, 1991); c) cardiovascular parameters (heart rate, central venous pressure, invasive arterial pressure). The decay of propofol whole blood concentrations, distribution, redistribution and elimination half lives were similar in CRF and in control patients. On the contrary, significantly different in CRF patients were propofol blood concentrations from two to ten minutes following the induction dose (lower), the area under concentration- time curve (AUC) (smaller), the mean resident time (longer), the total body clearance (greater), the volumes of distribution at steady state and during the elimination phase (larger). The larger volumes of distribution are closely correlated with the significantly lower albumin concentrations in the uremic patients. An accelerated hepatic biotransformation is one of the possible explanations for the greater total body clearance of propofol in the uraemic patients: in fact an increased glucuronyltrasferase activity and glucuronoconjugation induced by phenols has been demonstrated in uraemia. On the other hand, large volumes of

    In order to analyze the number and length of the renal arteries and to evaluate abnormalities of the renal parenchyma and vessel, digital subtraction angiogram images of 105 potential renal donors (45 men and 60 women aged 17-66 years) were studied retrospectively. For the entire series, 31 donors had multiple renal arteries on one side (15 on the left, 11 on the right) and 5 donors on the both sides. 89 donors were family related either parents or siblings of recipients. The estimation of the length of the renal artery was based on the mean height of the second lumbar vertebral body (L2). The right renal artery is significant longer than on the left and measured more than the height of L2 vertebral body in 84 cases on the right and 60 cases on the left. Twenty two donors underwent right nephrectomy due to presence of multiple renal arteries on the left (N=14), proximal bifurcation of left main renal artery (N=3), and young females in reproductive age (N=5). Unexpected abnormalities found with angiogram were seen in 7 cases and they include renal artery stenosis (N=2), renal cysts (N=4) and focal infarction (N=1). In cases of the renal cysts and focal infarction, there were no serious complications related to the abnormalities. It is conclude that intra-arterial digital subtraction angiography is safe and efficient method to image renal anatomy of the potential renal donors.

    Due to ongoing poor availability of organs, increasingly patients from developed countries are reported to be travelling abroad for renal transplants. We aimed to assess the extent and characteristics of this trend across the UK and Republic of Ireland. A questionnaire-based cross-sectional survey; 397 renal consultants from 33 hospitals with renal units across the UK and the Republic of Ireland were contacted through email and 62 replied (16%). Fifty-seven out of 62 (93%) renal consultants managed transplant patients, and of these 36/57 (63%) had managed at least one patient who had undergone a transplant abroad. The most popular reason reported for doing this was being on the UK or Republic of Ireland transplant list but seeking a shorter wait. Respondents reported commencement by overseas doctors of appropriate routine post-transplant prophylaxis with the following medications in all cases they had encountered as follows: co-trimoxazole 12%, isoniazid 3%, anti-fungals 0%, and Cytomegalovirus prophylaxis or treatment 0%. Fourty-four percent of renal consultants reported having some prior warning of a patient undergoing a renal transplant abroad. Renal transplant tourism has become widely established in the UK and the Republic of Ireland, and care for these patients is often suboptimal. Furthermore, the opportunity exists for pre-transplant counselling. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Treatment of chronic hepatitis C virus (HCV) infection after renal allograft transplantation has been an obstacle because of contraindications associated with IFN-based therapies. Direct-acting antiviral agents are highly efficient treatment options that do not require IFN and may not require ribavirin. Therefore, we assessed the efficacy and safety of sofosbuvir and ledipasvir in renal transplant patients with chronic HCV infection. Fifteen renal allograft recipients with therapy-naive HCV genotype (GT) 1a, 1b, or 4 were treated with the combination of sofosbuvir and ledipasvir without ribavirin for 8 or 12 weeks. Clinical data were retrospectively analyzed for viral kinetics and for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, laboratory values, and potential adverse effects. Ten patients (66%) exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 4; HCV GT1b, n = 6). The other 5 patients exhibited a virologic response within 8 (HCV GT 1b, n = 4) or 12 weeks (HCV GT4, n = 1). One hundred percent of patients exhibited sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Adverse events were scarce; renal transplant function and proteinuria remained stable. Importantly, dose adjustments for tacrolimus were necessary for maintaining sufficient trough levels. The described regimen appears to be safe and effective for patients after renal transplant and is a promising treatment regimen for eradicating HCV in this patient population.

    Patients on chronic dialysis are prone to developing acquired cystic kidney disease (ACKD), which may lead to the development of renal cell carcinoma (RCC). The risk factors for the development of RCC so far have not been determined in pre-dialysis patients with co-existent renal disease. The aim of this study was to evaluate the clinico-pathological features of RCC in pre-dialysis patients with associated renal diseases or in those undergoing chronic dialysis and renal transplantation. We studied 32 kidneys from 31 patients with RCC and associated renal diseases. Of those, 18 kidneys were from 17 patients not on renal replacement therapy (RRT) when diagnosed with RCC; 14 patients received dialysis or dialysis followed by renal transplantation. Several clinico-pathological features were analysed and compared between the two groups. Overall, there was a preponderance of males (75%); nephrosclerosis was the predominant co-existent disease (31%). The median intervals from renal disease to RCC in the dialysis and transplanted groups were significantly longer than in the pre-dialysis group (15.8+/-1.1 vs 2.4+/-0.7 years, P<0.0001). In contrast to pre-dialysis RCC, the dialysis and transplant RCC groups had greater frequency of ACKD (100 vs 28%, P<0.0001), papillary type RCC (43 vs 11%, P<0.05) and multifocal tumours (43 vs 5%, P<0.05). At the end of the study, 71% of dialysis and transplanted patients and 72% of pre-dialysis patients were alive. ACKD develops in dialysis patients, as it does in those with renal disease prior to RRT. The duration of renal disease, rather than the dialysis procedure itself, appears to be the main determinant of ACKD and RCC. The RCC occurring in patients with ACKD and prolonged RRT is more frequently of the papillary type and multifocal than the RCC occurring in patients with no or few acquired cysts and a short history of renal disease. Long-term outcomes did not differ between the two groups.

    molecules that act as allosteric activators of the CaSR and they are in their initial face of clinical development. Although the experience with these drugs is limited, they have shown to effectively lower parathyroid hormone levels in patients with hyperparathyroidism secondary to end-stage renal failure without inducing important side-effects. Thus calcimimetic compounds have considerable potential as new drugs for the treatment of secondary hyperparathyroidism and uremic bone disease.

    Full Text Available Immunosuppressive medicines are characterized by specific pharmacokinetic profile which requires therapy monitoring by means of measuring their blood concentrations. Therapy monitoring, by means of determining blood concentration of the medicine, enables application of an optimal individual immunosuppressive therapy. Due to its variable pharmacokinetics, and small therapeutic index and potential interaction with numerous other medicines, the post-operative monitoring of immunosuppressive medicines is an essential element of therapy protocol for renal transplantation patients. Therapy monitoring represents an efficient way to reduce adverse effects of immunosuppressive medicines and to prevent transplantation rejection, by means of adapting the doses in renal transplantation patients. Determining the concentration of immunosuppressive medicines is of special importance in the modified dosing for patients with renal insufficiency. Pharmacokinetic analysis is important for proper interpretation of immunosuppressive medicines' blood concentrations. The interpretation of the received results must be multidisciplinary, considering that there are numerous factors of variability of patients and immunosuppressive medicines.

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

    Full Text Available Retroperitoneal lymphocele is a common complication of renal transplantation. Here, we report the case of a 67-year-old woman with massive ascites after fenestration surgery for a lymphocele that developed following renal transplantation. She had been on continuous ambulatory peritoneal dialysis for 9 years. Living donor renal transplantation was performed and an intrapelvic lymphocele subsequently developed. The lymphocele did not resolve after aspiration therapy; therefore, laparoscopic fenestration was performed. Although the lymphocele disappeared, massive ascites appeared in its stead. Half a year later, the ascites was surgically punctured, which then gradually resolved and disappeared 6 weeks later. Aspiration therapy should be considered in patients on long-term peritoneal dialysis, although laparoscopic fenestration is safe and effective.

    Kidneys from elderly deceased patients and otherwise marginal donors may be considered for transplantation and a pretransplantation histopathological score for prediction of postoperative outcome is warranted. In a retrospective design, 29 baseline renal needle biopsies from elderly deceased donors...... wall thickness of arteries and/or arterioles. Nineteen renal baseline biopsies from 15 donors (age: 64 ± 10 years) were included and following consensus the histopathological score was 4.3 ± 2.1 (intraclass correlation coefficient: 0.81; confidence interval: 0.66-0.92). The donor organs were used...... for single renal transplantation (recipient age: 47 ± 3 years). Two grafts were lost after the transplantation. In the remaining 17 recipients the 1-year creatinine clearance (54 ± 6 mL/min) correlated to the baseline histopathological score (r(2) = 0.59; p

    Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated. Twenty-two (0.58%) patients underwent minimally invasive surgery for renal graft lithiasis. The mean age was 41.6 years, and duration between RT and surgical intervention was 27.3 months (range 3-67). The mean stone size was 11.6 mm (range 4-29). Stones were located in the urethra in 1, bladder in 2, ureter in 9, renal pelvis in 7 and calices in 3 patients. Surgical treatment included percutaneous nephrolithotomy in 1, cystoscopic lithotripsy in 3, flexible ureteroscopic lithotripsy in 6 and rigid ureteroscopic lithotripsy in 12 patients. No major complications were observed. One patient (4.5%) who underwent flexible ureteroscopy developed postoperative urinary tract infection. All patients were stone-free except two (9%) patients who required a second-look procedure after flexible ureteroscopic lithotripsy for residual stones. Stone recurrence was not observed in any patient during a mean follow-up duration of 30.2 months (range 8-84). Renal transplant lithiasis is uncommon and minimally invasive surgical treatment is rarely performed for its treatment. Endourological surgery may be performed safely, effectively and with a high success rate in these patients.

    Frequency of pulmonary complications after renal transplant has been reported to range from 3% to 17%. The objective of this study was to evaluate renal transplant recipients admitted to an intensive care unit to identify incidence and cause of acute respiratory failure in the postoperative period and compare clinical features and outcomes between those with and without acute respiratory failure. We retrospectively screened the data of 540 consecutive adult renal transplant recipients who received their grafts at a single transplant center and included those patients admitted to an intensive care unit during this period for this study. Acute respiratory failure was defined as severe dyspnea, respiratory distress, decreased oxygen saturation, hypoxemia or hypercapnia on room air, or requirement of noninvasive or invasive mechanical ventilation. Among the 540 adult renal transplant recipients, 55 (10.7%) were admitted to an intensive care unit, including 26 (47.3%) admitted for acute respiratory failure. Median time from transplant to intensive care unit admission was 10 months (range, 0-67 mo). The leading causes of acute respiratory failure were bacterial pneumonia (56%) and cardiogenic pulmonary edema (44%). Mean partial pressure of arterial oxygen to fractional inspired oxygen ratio was 174 ± 59, invasive mechanical ventilation was used in 13 patients (50%), and noninvasive mechanical ventilation was used in 8 patients (31%). The overall mortality was 16.4%. Acute respiratory failure was the reason for intensive care unit admission in almost half of our renal transplant recipients. Main causes of acute respiratory failure were bacterial pneumonia and cardiogenic pulmonary edema. Mortality of patients admitted for acute respiratory failure was similar to those without acute respiratory failure.

Materials and methods. 5 patients, heart valve replacement was performed with a func- tioning kidney transplant at a satisfactory its function. The average age of patients at the time of cardiac surgery was 38,8 ± 12,6 years, among whom were two (40% men and 3 (60% women. The interval between renal transplantation and heart surgery was 40,3 ± 44,1 (2 to 120 months. Prior to kidney transplantation, all patients were on renal replacement therapy with hemodialysis program for 50,2 ± 48,6 months. In 4 of the 5 patients of heart disease was the cause of infective endocarditis. Results. Average time IR was 81,2 ± 21,7 minutes , the average time of aortic clamping 63,6 ± 20,9 minutes and hypothermia during CPB 29,2 ± 3,2 °C. All patients were implanted with double-leaf mechanical prostheses "MedEng-2" and "SarboMedics". All 5 patients in sa- tisfactory condition were discharged from the hospital. The average duration of the postoperative period was 14,2 ± 3,4 days. All patients had relatively smooth flow after surgery, no infectious complications, a satisfactory renal transplant function and prosthetic heart valves. In the late period in four patients and transplant graft func- tion is satisfactory in terms of the observation of 5 years, 3 years and 6 months after surgery. Conclusion. Our experience shows the possibility of successful correction of heart defects in IR in renal transplant recipients.

    Arteriovenous fistula (AVF) is an uncommon but well-known complication of percutaneous renal biopsy. Most postbiopsy AVFs are asymptomatic and regress spontaneously; however, some AVFs result in hypertension, hematuria and renal insufficiency. Transplant renal artery stenosis (TRAS) is a potentially curable cause of posttransplant arterial hypertension, allograft dysfunction and graft loss. Whether postbiopsy AVF superimposed on TRAS also regresses spontaneously is unknown. The authors present a case of acute renal failure in a 56-year-old male renal allograft recipient with the combination of postbiopsy AVF and TRAS. At first, the authors performed percutaneous angioplasty with stent implantation for the TRAS, but the AVF gradually enlarged. Eighteen months later, the patient began to experience hypertension, and his serum creatinine level increased; he received transcatheter arterial embolization therapy for enlarged AVF, and his renal function returned to baseline level.

    2017-01-01

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

Our objective was to examine management of mineral metabolism in patients wait-listed for renal transplant and to determine the impact on cardiac perfusion imaging.Methods: Data was collected retrospectively on patients wait-listed for a renal transplant (n = 105, being either active (n = 73 and on hold (n = 32. Demographic data, medications, serum concentrations of calcium, phosphate, parathyroid hormone, and cardiac perfusion imaging studies were collected from the electronic health record. Chi-square and Student’s t-tests were used to compare active and on-hold patients as appropriate. Logistic regression was used to examine variables associated with worsening cardiac imaging studies.Results: The wait-listed patients were of mean age 56 ± 14 years and had been on dialysis for 1329 ± 867 days. On-hold patients had received a significantly greater total dose of calcium (2.35 ± .94 kg versus 1.49 ± 1.52 kg; P = 0.02 and were more likely to have developed worsening cardiovascular imaging studies (P = 0.03. Total doses of calcium and calcitriol were associated with worsening cardiovascular imaging studies (P = 0.05.Conclusion: Patients on hold on the renal transplant waiting list received higher total doses of calcium. A higher total dose of calcium and calcitriol was also associated with worsening cardiovascular imaging. Time on dialysis before transplant has been associated with worse post-transplant outcomes, and it is possible that the total calcium and calcitriol dose

    After renal transplantation recovery in nutritional status occurs during the first year. We assessed the changes in nutritional status after transplantation in 145 transplant recipients (94 males, 51 females). Patients were evaluated immediately after renal transplant (baseline data) and at 6 months' follow-up. Analysis included body mass index (BMI), body composition (skin fold and arm circumference), and estimated body composition (calculated percent of fat, arm circumference, arm muscle circumference, and arm muscle area). Other data obtained from medical records included renal function (MDRD) serum albumin and lipid profile. At baseline evaluation (21 ± 15 days posttransplant), mean BMI was 23.9 ± 3.9 kg/m(2), serum albumin was 3.7 ± 0.7 g/dL, and lipid profile showed (cholesterol 158.5 ± 52.7 mg% and triglycerides 135.9 ± 91.8 mg%.

    Tertiary hyperparathyroidism (3HPT) is defined as the persistent hyperproduction of parathyroid hormone and resulting hypercalcemia after renal transplantation. Here, we examine the utility of radioguided parathyroidectomy (RGP) in patients with 3HPT. We reviewed a prospective surgery database containing 80 3HPT patients who underwent RGP from January 2001-July 2014 at our institution. We evaluated patient demographics, operative management, radioguided neoprobe utilization, and operative outcomes. Data are reported as mean ± standard error of the mean. The mean age of the patients was 52 ± 1 y, and 46% were male. A total of 69 patients had hyperplasia and received subtotal parathyroidectomy, whereas 5 patients had double adenomas and 6 patients had single adenomas. The average calcium level among 3HPT patients was 10.8 ± 0.1 mg/dL preoperatively and 8.7 ± 0.1 mg/dL postoperatively. In vivo radioguided counts normalized to background counts averaged 145 ± 4%, whereas ex vivo counts normalized to background counts averaged 69 ± 5%. All but one ex vivo count was >20%. Ectopically located glands were successfully localized in 38 patients using the gamma probe. Ex vivo percentage did not correlate with parathyroid gland weight, preoperative parathyroid hormone, or preoperative calcium. Our radioguided approach achieved normocalcemia in 96% of 3HPT patients undergoing RGP; two patients developed recurrent disease. In this series, all enlarged parathyroid glands were localized and resected using the gamma probe. Thus, RGP reliably localizes adenomatous, hyperplastic, and ectopically located glands in patients with 3HPT, resulting in high cure rate after resection. Copyright © 2015 Elsevier Inc.

    Transplanting kidneys into patients with an ileal conduit has become acceptable practice, and is usually well tolerated. We present the cases of two such patients who later presented as emergencies with anuria due to infarction of the ileal conduit. Both required operative intervention, and in both cases the renal function returned to its pre-operative level. The cases illustrate an important differential diagnosis of anuria in this group of transplant patients.

    Full Text Available Cutaneous alternariosis is an uncommon fungal infection that most commonly presents in organ transplant patients on immunosuppressive therapy. There are no clinical trials or guidelines to guide treatment of this condition, however itraconazole is the most commonly used antifungal in published cases. Here we report on a case of cutaneous alternariosis in a renal transplant recipient treated with a newer antifungal, posaconazole. A review of published reports of cutaneous alternariosis since 2008 is also discussed.

    Full Text Available Keratoacanthoma (KA is a benign keratinocytic neoplasm that spontaneously regresses after 3-6 months and shares features with well-differentiated squamous cell carcinoma (SCC. An increased incidence of both KA and non-melanoma skin tumor, including SCC, is seen among immunosuppressed, organ-transplant recipients. In this report we describe a case of KA accompanied by multiple lung SCCs developing in a renal transplant recipient.

    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.

    Full Text Available Background Opportunistic infections have become much more considerable in the last decades, especially in immunocompromised patients and due to the medical interventions. Cryptosporidium is a pathogenic protozoan parasite causing diarrhea in children and some times acts as a life threatening opportunistic pathogen in the immunocompromised adults. Objectives This study aimed to investigate the presence of Cryptosporidium infection among patients undergone renal transplantation, who are at risk for this infection. Patients and Methods This was a cross-sectional study and the sample collection consisted of 180 renal transplanted patients referred to Shaheed-Beheshti Hospital, Hamadan city, Iran. The stool specimens were concentrated using formalin-ether technique and then the fecal smears were prepared from the sediments. Afterwards, the slides were stained using the Ziehl-Neelsen staining method and then examined for the presence of Cryptosporidium oocysts. Results One out of 180 fecal samples was positive for Cryptosporidium infection. The infected patient was a 51-year-old woman who had a renal transplantation six years earlier, with continuous use of CellCept® (mycophenolate mofetil and prednisolone. The patient had been referred to the hospital with gastrointestinal symptoms. Conclusions Based on the results of this study the prevalence of cryptosporidiosis was very low in renal transplanted patients in Hamadan city, Iran. It could be concluded that cryptosporidiosis is not a life threatening risk in this region and it probably showed well post-transplantation hygienic status of the patients and/or low oocysts load in the area.

    In transplant patients with localized prostate cancer, irradiation is not proposed as often as it is in healthy adults because of the post-radiation risks, such as ureteral stenosis and gastrointestinal toxicity as the result of fragile tissue. The objective of the study was to analyze the efficacy and feasibility of intensity-modulated radiation therapy (IMRT) for prostate cancer in renal transplant recipients (RTRs). Between May 2005 and December 2014, all patients who had undergone IMRT for clinically localized prostate cancer at our institution were retrospectively identified (n = 365). Of these patients, 2 had a history of renal transplantation. We reviewed all available clinical data. One patient had a functioning graft and the other had restarted hemodialysis 7 years after the transplantation. The mean time from renal transplantation to prostate cancer diagnosis was 11 years. The mean follow-up after irradiation was 43 months. The 2 patients remain free of prostate-specific antigen progression. There was no severe acute and chronic genitourinary and gastrointestinal toxicity. Renal function of the patient with a functioning graft as measured by serum creatinine was stable during and after the irradiation. IMRT is feasible and acceptable as a minimally invasive treatment in the carefully selected RTRs with localized prostate cancer. This treatment should be considered a good option for RTRs with localized prostate cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate the transplantation of both kidneys from donors under 3 years old to older pediatric recipients, in order to provide adequate renal mass and improve graft survival. Seven patients received a double kidney transplant from a donor under 3 years old (mean age 2.7 years). The primary renal disease was obstructive uropathy in two patients, and hemolytic uraemic syndrome, tuberous sclerosis, nephronoptisis, reflux nephropathy and nephrotic syndrome (one patient each). Recipients were 14-18 years old and had a mean height of 165.2 cm. Five were in dialysis and it was the second transplantation for two. Both kidneys were sequentially placed in the same iliac fossa; the first was placed the most cranially with the second placed caudal to the first. The surgical technique was similar to that used to place a single graft. Immunosuppression induction employed monoclonal antibodies followed by a triple therapeutic regime (mofetyl micofenolate/steroids/tacrolimus). Diuresis was started immediately with all the grafts and there was no thrombosis in any patient. One patient lost both grafts due to recurrence of her primary disease. Another patient developed lymphocele 1 year post transplant and required laparoscopic drainage. The grafts in six patients are doing well after a follow up of 1 to 7 years. Double transplant of both kidneys from a donor under 3 years old can provide sufficient renal mass for adequate renal function and does not present a higher risk of complications.

    Gastrointestinal complications are common in renal transplant recipients and may arise from any part of the gastrointestinal tract. Irritable bowel syndrome (IBS) is highly common in the general population, but the status is not known in renal transplant patients. In this study, we evaluated the prevalence of IBS and its association with health-related quality of life (HRQOL), anxiety, and depression in renal transplant patients. One hundred and ninety-eight patients were enrolled in this study. Sociodemographic and laboratory variables were recorded. Severity of depressive and anxiety symptoms and HRQOL were assessed by the Beck Depression Inventory, State-Trait Anxiety Inventory, and Short Form 36 (SF-36), respectively. Diagnosis of IBS was based on Rome III criteria. The mean age was 38 ± 10 years and 61% were male. The mean transplant duration was 62 ± 54 months. Among 198 patients, 55 (27%) had IBS. Patients with IBS had lower SF-36 scores and had higher depressive and anxiety symptoms than patients without IBS. IBS is highly prevalent in renal transplant patients. The presence of IBS is closely related with HRQOL anxiety and depression.

    Patients with methylmalonic acidemia (MMA) may develop many complications despite medical treatment, in particular, severe central nervous system damage and chronic kidney disease (CKD). A kidney transplant may partially correct the metabolic dysfunctions. Liver, kidney and combined liver-kidney transplantations have been advocated but no guidelines are available to identify the most suitable organ to transplant. Four patients with MMA (mut° phenotype) received a kidney graft because of repeated metabolic decompensations, with progression to CKD in 3 patients (end-stage kidney disease in two patients and CKD stage III in one patient with an estimated glomerular filtration rate [eGFR] of 40ml/min/1.73m(2)) but normal renal function in one (eGFR of 93ml/min/1.73m(2)) before transplantation. The medium age at transplantation was 7.9y (5-10.2) and the median follow-up was 2.8years (1.8-4.6). Renal transplantation improved the relevant metabolic parameters in 4/4 patients and renal function in the patients with CKD. Plasma and urinary MMA levels immediately decreased and remained normal or subnormal (mean values of plasma MMA before transplantation 1530μmol/L versus 240μmol/L after transplantation, and mean values of urine MMA before transplantation 4700mmol/mol creatinine versus 2300mmol/mol creatinine after transplantation). No further acute metabolic decompensation was observed and protein-intake was increased from 0.60 to 0.83g/Kg/day. One patient transplanted at age 9.7years developed a hepatoblastoma at age 11years with subsequent neurological complications and eventually died. The three other patients are alive. Two of them remained neurologically stable. The 3rd patient who displayed choreoathetosis transiently improved his neurological condition immediately after transplantation and then remained stable. Kidney transplantation represents an interesting alternative therapeutic option in methylmalonic aciduria, for renal complications but also as a "cellular

    We describe the case of a 54-year-old patient after renal and heart transplantation in whom uncontrolled hypertension was diagnosed. Despite combined antihypertensive therapy, no significant therapeutic effect was achieved. Clinical assessment of ambulatory blood pressure monitoring (ABPM) revealed the ineffectiveness of a bisoprolol, nitrendypin, klonidyn, ramipryl, furosemide, and doxasosine combination used at high doses. High blood pressure levels with their effect on a hypertrophic transplanted heart (left ventricular mass 254 g) and poor renal graft function (39 mL/kg/min) posed an extremely high risk of future cardiovascular complications, and were the reason to perform a native renal arteries denervation. The procedure was carried out through the right femoral artery with the use of a 6F guiding catheter. During a 1-year observation, significant decreases in ABPM systolic and diastolic blood pressures were observed after the procedure (168/88 mm Hg vs 154/77 mm Hg, respectively). Moreover a significant regression of left ventricular mass (215 g/m(2)) and stable renal graft function were noted. The presented case shows that native renal arteries denervation may be successful and safe in kidney and heart transplant recipients. Moreover, during the 1-year follow-up, the reduction in blood pressure was followed by a reduction in transplanted heart hypertrophy, both leading to regression of cardiovascular risk for the patient.

    Full Text Available The kidney is a very important complicated filtering organ of the body. When the kidney reaches stage 5 chronic kidney disease, end stage renal failure, the preeminent therapy is renal transplantation. Although it is the best form of treatment, lack of kidney donors is still challenging. Therefore, all efforts should be employed to prolong the survival rate of the transplanted kidney. However, graft dysfunction (e.g., acute rejection is one of the serious barriers to long term kidney transplant survival. Currently, graft dysfunction’s gold standard of diagnosis is renal biopsy. Although renal biopsy is helpful, it is not preferred due to its invasive nature, high morbidity rates, and expensiveness. Therefore, noninvasive imaging techniques have become the subject of extensive research and interest, giving a strong promise to replace, or at least to decrease, biopsy usage in diagnosing graft dysfunction. This survey will discuss not only the current diagnosis and treatment of graft dysfunction but also the state-of-the-art imaging techniques in detecting acute renal transplant rejection.

    Weight gain and malnutrition after kidney transplantation is common and the resulting overweight and obesity is associated with serious health complications. By contrast, the prevalence of malnutrition in patients with renal transplantation and its impact on the outcome of kidney transplantation is underestimated. The aim of this study was to evaluate the nutritional status of renal transplant patients and determine if the five-year follow-up, these patients undergo alterations that suggest nutritional deterioration. The sample consisted of 119 renal transplant patients who attended for five years post-transplant consultation. All patients measurements of total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides and ferritin (Ft) were performed. and anthropometric measurements were made of weight, height and BMI. Patients were divided into three groups according to GFR Group 1: nutritional biochemical parameters in general, likewise the nutritional status is closely related, and is directly proportional to the function of the graft.

    Full Text Available Abstract Introduction Neurological complications leading to morbidity and mortality are not frequent in renal transplant recipients. Here, we report a renal transplant recipient who presented with diminished strength in his limbs probably due to multiple etiologies of axonal sensorimotor polyneuropathy, which resolved with intravenous immunoglobulin. Case presentation A 49-year-old Iranian male renal transplant recipient with previous history of autosomal dominant polycystic kidney disease presented with diminished strength in his limbs one month after surgery. Our patient was on cyclosporine A, mycophenolate mofetil and prednisone. Although a detected hypophosphatemia was corrected with supplemental phosphate, the loss of strength was still slowly progressive and diffuse muscular atrophy was remarkable in his trunk, upper limb and pelvic girdle. Meanwhile, his cranial nerves were intact. Post-transplant diabetes mellitus was diagnosed and insulin therapy was initiated. In addition, as a high serum cyclosporine level was detected, the dose of cyclosporine was reduced. Our patient was also put on intravenous ganciclovir due to positive serum cytomegalovirus immunoglobulin M antibody. Despite the reduction of oral cyclosporine dose along with medical therapy for the cytomegalovirus infection and diabetes mellitus, his muscular weakness and atrophy did not improve. One week after administration of intravenous immunoglobulin, a significant improvement was noted in his muscular weakness. Conclusion A remarkable response to intravenous immunoglobulin is compatible with an immunological basis for the present condition (post-transplant polyneuropathy. In cases of post-transplant polyneuropathy with a high clinical suspicion of immunological origin, administration of intravenous immunoglobulin may be recommended.

    Return to work is an objective parameter used worldwide to evaluate the success of organ transplantation and is especially feasible after renal transplantation. This study sought to describe the frequency of return to work after renal transplantation and related characteristics. Retrospective cohort of 511 isolated kidney transplant recipients was recruited from a Brazilian referral center from January 2005 to December 2009; all were matched to the public social security database to determine inclusion and benefit awards, as well as the rate of resumption of contributions to the public social security system, a surrogate marker of work rehabilitation. Characteristics associated with work return were analyzed. No social security records were found for 28 subjects. The remaining 483 subjects had a mean age of 45±13 years; 62% were male; 401 (83%) received some public social security benefit; 298 were paying dues and could, therefore, receive temporary or permanent disability benefits. Of these, 78 subjects made social security payments after transplantation, resulting in a work return rate of 26% (95% confidence interval, 21-32). Younger age, living donor graft, and chronic glomerulonephritis were significantly associated with return to work. In Brazil, most renal transplant recipients are on social security benefits, but only a small proportion return to work after surgery. Clinical characteristics may help define work resumption trends.

    Cyclosporine (CsA) is frequently initiated as induction therapy in patients undergoing orthotopic heart transplantation, but our experience has identified a significant rate of post-operative renal dysfunction. We therefore devised a renal-sparing cyclosporine-free induction regimen consisting of the early administration basiliximab, an interleukin-2 receptor monoclonal antibody, followed by the late initiation of cyclosporine on post-operative Day 4. Between September 1998 and December 1999, we treated 25 patients at risk for post-operative renal dysfunction (high-risk basiliximab group) with the new induction regimen and another 33 patients not at risk (low-risk CsA group) for renal dysfunction with our standard cyclosporine protocol. We identified a historical control group (1996 through 1998) of 32 patients at risk for renal dysfunction (high-risk CsA group) who had received our standard cyclosporine protocol. The increase in serum creatinine levels after transplantation was less in the high-risk basiliximab group (-0.1 +/- 0.7) than in the high-risk CsA group (0.5 +/- 1.0, p cyclosporine after cardiac transplantation without an increase in rejection and reduces the risk of post-operative renal dysfunction.

    Liver transplantation is associated with a significantly increased risk of de novo malignancies, but for renal cancer this risk is less clear. We therefore performed a meta-analysis of published studies to determine whether renal cancer risk in liver transplant recipients (LTRs) was increased. To obtain a more precise conclusion, a systematic search was performed in PubMed and Web of Science databases until June 10, 2015. Standardized incidence ratio (SIR) corresponding 95% confidence interval (CI) were used to estimate risk of renal cancer in LTRs. Heterogeneity test, sensitivity analysis, and publishing bias were also performed. We identified 8 eligible studies and performed a meta-analysis on data of 49,654 LTRs with a total follow-up of 121,514.6 patient-years. The SIR for renal cancer was identified a 3.275-fold higher SIR (95% CI: 1.857-5.777; P renal cancer. Such association suggests that yearly routine post-transplant surveillance is need for renal cancer in LTRs. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

    Renal failure is a frequent complication in liver transplant recipients and is associated with increased morbidity and mortality. A variety of risk factors for the development of renal failure in the pre- and post-transplantation periods have been described, as well as at the time of surgery. To reduce the negative impact of renal failure in this population, an active approach is required for the identification of those patients with risk factors, the implementation of preventive strategies, and the early detection of progressive deterioration of renal function. Based on published evidence and on clinical experience, this document presents a series of recommendations on monitoring RF in LT recipients, as well as on the prevention and management of acute and chronic renal failure after LT and referral of these patients to the nephrologist. In addition, this document also provides an update of the various immunosuppressive regimens tested in this population for the prevention and control of post-transplantation deterioration of renal function.

    2011-01-01

    Full Text Available Introduction: Secondary hyperparathyroidism (SHPT is an insidious disease that develops early in the course of chronic kidney disease (CKD and increases in severity as the glomerular filtration rate deteriorates. Recent studies have identified fibroblast growth factor-23 (FGF23 as a new protein with phosphaturic activity. It is mainly secreted by osteoblasts and is now considered the most important factor for regulation of phosphorus homeostasis. It is not yet proven if there is any direct relation between parathyroid hormone (PTH and FGF23. The present study aims to evaluate the relation between serum FGF23, phosphorus, and PTH in end-stage renal disease in patients with SHPT on regular hemodialysis. Materials and Methods: Forty-six consecutive CKD adult patients (case group and 20 healthy adults (control group were included in the study. All patients had SHPT and were on regular hemodialysis. Both groups were subjected to full medical history, clinical examination and biochemical studies. Serum phosphorus, calcium, ferritin, hemoglobin level, blood urea, creatinine, PTH, and FGF23 were analyzed. Results: Levels of FGF23 were significantly higher in the case group in comparison with those in the control group, viz., 4-fold, and positively correlated with PTH. Phosphorus levels in the case group were significantly high in spite of the increasing levels of FGF23. Both PTH and FGF23 were positively correlated with phosphorus and negatively with hemoglobin levels. Conclusion: SHPT and FGF23 may have a partial role in the development of anemia in patients with CKD. FGF23 could be a central factor in the pathogenesis of SHPT. Its role in controlling hyperphosphatemia in CKD is vague.

    Osteoprotegerin (OPG) acts by neutralizing the receptor activator of nuclear factor-kappaB ligand (RANKL), the primary mediator of osteoclast differentiation, function, and survival. We examined whether OPG could affect the bone loss associated with chronic kidney disease (CKD) in a rodent model of CKD and secondary hyperparathyroidism (SHPT). SHPT was induced in rats by 5/6 nephrectomy (5/6 Nx) and a 1.2% P/0.6% Ca(2+) diet. Starting 1 week after 5/6 Nx, rats were treated with vehicle (veh) or OPG-Fc (3 mg/kg, intravenously) every 2 weeks for 9 weeks. At baseline, 3, 6, and 9 weeks, blood was taken and bone mineral density (BMD) and bone mineral content (BMC) were assessed by dual-energy X-ray absorptiometry. Serum parathyroid hormone (sPTH) levels reached 912 pg/ml in 5/6 Nx rats vs. 97 pg/ml in shams at 9 weeks. OPG-Fc had no effect on sPTH or Ca(2+) levels throughout the 9-week study, indicating that SHPT was a renal effect independent of bone changes. At 3 weeks, 5/6 Nx-veh rats had osteopenia compared with sham-veh rats and 5/6 Nx-OPG-Fc rats had significantly higher percent changes in whole-body BMC, leg BMD, and lumbar BMD versus 5/6 Nx-veh rats. By 6-9 weeks, elevated sPTH was associated with reversal of bone loss and osteitis fibrosa in the proximal tibial metaphysis. OPG-Fc decreased this sPTH-driven high bone turnover, resulting in augmented thickness of proximal tibial trabeculae in 5/6 Nx rats. Thus, RANKL inhibition with OPG-Fc can block the deleterious effects of continuously elevated sPTH on bone, suggesting that RANKL may be an important therapeutic target for protecting bone in patients with CKD and SHPT.
