Abstract
Background There is concern about the impact of immunosuppressive agents taken by male kidney transplant (KT) recipients on the risk of foetal malformations. The aim of our survey was to estimate the paternity rate and the outcomes of pregnancies fathered by kidney transplanted males. Methods This survey analysed 1332 male KT recipients older than 18 years, followed in 13 centres in France. A self-reported questionnaire was used to collect data on the patients, treatments at the time of conception and the pregnancy outcomes. Results The study included data on 349 children from 404 pregnancies fathered by 232 male KT recipients. The paternity rate was 17% (95% CI [15–20]). There were 37 (9%, 95% CI [7–12]) spontaneous abortions, 12 (3%, 95% CI [2–5]) therapeutic abortions, 2 (0.5%, 95% CI [0.1–1]) still births, and 13 (4%, 95% CI [2–6]) malformations reported. Compared to the general population, there was no difference in the proportion of congenital malformations nor unwanted outcomes whether the father was exposed or not to immunosuppressive agents. Conclusions This survey does not provide any warning signal that pregnancies fathered by male patients exposed to immunosuppressive agents, notably the debated MMF/MPA, have more complications than pregnancies in the general population.

Abstract
BackgroundThe French healthcare system offers the possibility of increasing the use of peritoneal dialysis (PD) by involving in patient care nurses who work in the private system.ObjectiveThis study was conducted to evaluate the impact of a private home-nurse network on one dialysis program.MethodsThis was a retrospective study of 239 dialysis patients who started dialysis in our center between 1 January 1998 and 31 December 2003.ResultsOf these 239 patients, 142 were treated with hemodialysis and 97 with PD during the study period. Among the PD patients, 36 of 97 were treated with assisted PD and 61 of 97 with self-care PD. Assisted-PD patients were older (74 ± 10 vs 52 ± 18 years, p < 0.001) and presented more comorbidity (Charlson Comorbidity Index 7 ± 2.5 vs 4.3 ± 2.4, p < 0.05) compared with self-care patients. Continuous ambulatory PD was the modality of choice in the assisted group (32/36). Assisted patients were frequently hospitalized (31/36); actuarial survival free of hospitalization at 6 months was 46%. Patients with nurse assistance had a high risk of peritonitis (actuarial survival free of peritonitis: 52% at 1 year). Technique survival was 85% at 6 months and 58% at 1 year. Actuarial patient survival was 90% at 6 months and 83% at 1 year.ConclusionAssisted PD enables increased use of PD in incident dialysis patients. However, in view of the comorbidities of the assisted-PD patients, the need for frequent hospitalization has to be taken into account in such a program.

Abstract
Hypocomplementemic urticarial vasculitis is a rare systemic vasculitis, affecting small vessels, characterised by chronicle urticaria, hypocomplementemia, and systemic manifestations. Renal involvement, whose prevalence varies between 9% and 60%, is mainly glomerular. We here report the case of a 59 years old woman presenting kidney failure, associated with chronicle urticaria and arthralgias. Laboratory investigation showed haematuria, proteinuria, hypocomplementemia and anti-SSa antibody positivity. A percutaneous kidney biopsy revealed focal and segmental glomerulonephritis associated with an acute interstitial nephritis. Hypocomplementemic urticarial vasculitis diagnosis was established after identifying anti-C1q antibodies. The lack of a dry syndrome, the negativity of a Schirmer test and the lack of sialadenitis on a salivary gland biopsy excluded an associated Gougerot-Sjögren Syndrome. The patient was treated with hydroxychloroquine and low-dose steroids, enabling a clinical and biological recovery. Of the 82 cases in the literature describing hypocomplementemic urticarial vasculitis associated nephropathies, 72 (88%) were a glomerular impairment, most frequently secondary to membranoproliferative glomerulonephritis. Only 6 (7%) tubulo-interstitial nephritis have been reported, 4 of them being associated with a glomerulonephritis. Patients were more likely to be women, aged in their third decade. The most frequent renal manifestations were haematuria (60%), and proteinuria (52%). Kidney failure was rarely observed (22%), with a fairly good renal prognosis. Hypocomplementemic urticarial vasculitis was associated with a systemic disease in 11 (13%) patients. In the absence of recommendations, the treatment strategy remains to be defined.

Abstract
Introduction Although kidney transplantation carries a survival benefit compared with dialysis, mortality, especially the first year after transplantation, is high in recipients older than 70. The aim of this study was to evaluate early death and graft failure, and to determine the risk factors associated with these events in this specific population. Methods All patients older than 70 years who received a kidney transplant between January 2000 and December 2014 in the North-West of France were included (n = 171). Baseline characteristics and outcomes after transplantation were studied. Kaplan-Meier analysis was performed to assess patient and graft survival, and Cox regression analysis to evaluate risk factors for graft failure and patient death. Results The mean recipient age was 73.3 ± 2.5 years. Death-censored graft survival at 1, 3, and 5 years were 82.6%, 78.7%, and 75.4%, respectively. Patient survival at 1, 3, and 5 years was 90.1%, 82.5%, and 68.1%, respectively. One year after transplantation, 17 patients (9.9%) were dead, mainly from infectious (58.5%) or cardiovascular disease (29.4%). According to the Cox multivariate analysis, the independent risk factors for death or graft failure during the first year were arrhythmia (odds ratio [OR] 2.26; 95% confidence interval [CI] 1.08–4.8), left-ventricular ejection fraction (LVEF) under 56% (OR 2.38; 95% CI 1.18–4.83), human leucocyte antigen (HLA) antibodies (OR 2.1; 95% CI 1.04–4.2), deceased donor from cardiovascular cause (OR 5.18; 95% CI 1.22–6.3), and acute rejection (OR 2.77; 95% CI 1.2–6.3). Conclusion In kidney transplant recipients older than 70 years, cardiac evaluation and immunosuppression optimization seem to be crucial to improve short-term patient and graft survival.

Abstract
Nowadays, several treatments exist to treat terminal chronic renal failure. Best results for the recipients are obtained with kidney transplantation concerning mortality and quality of life. Transplantation is also the cheaper option for society. Living kidney donation raises the issue of the becoming of the donor, an absolutely healthy subject who gets to a surgical procedure. The becoming of living kidney donors has been compared with the one of controls subjects in several studies. The evaluations focused on the complications of nephrectomy in the short and long-term: kidney failure, hypertension, proteinuria, possibility of pregnancy, quality of life, and mortality. The first results did not show any risk linked to kidney donation, compared to general population. However, since 2013, kidney donors were found at higher risk for kidney failure and even for mortality, compared with controls selected like donor candidates. The risk of kidney donation is nevertheless acceptable and minimal, on the condition of rigorous selection of candidates and regular follow-up.

Abstract
We report the case of a human immunodeficiency virus-seropositive patient whose initial kidney transplant failed because of BK polyomavirus-induced nephropathy, and who underwent a second transplantation 3 years later. BK viruria was detected 1 day after transplantation. After 1 month, BK viremia developed along with a donor-specific antibody. After decreasing tacrolimus and mycophenolic acid and 2 courses of intravenous immunoglobulins, BK viremia and donor-specific antibody permanently disappeared, with stable renal function.

Abstract
Long-term outcomes in renal transplant recipients withdrawn from steroid and submitted to further minimization of immunosuppressive regimen after 1 year are lacking. In this multicenter study, 204 low immunological risk kidney transplant recipients were randomized 14.2 ± 3.7 months post-transplantation to receive either cyclosporine A (CsA) + azathioprine (AZA; n = 53), CsA + mycophenolate mofetil (MMF; n = 53), or CsA monotherapy (n = 98). At 3 years postrandomization, the occurrence of biopsy for graft dysfunction was similar in bitherapy and monotherapy groups (21/106 vs. 26/98; P = 0.25). At 10 years postrandomization, patients' survival was 100%, 94.2%, and 95.8% (P = 0.25), and death-censored graft survival was 94.9%, 94.7%, and 95.2% (P = 0.34) in AZA, MMF, and CsA groups, respectively. Mean estimated glomerular filtration rate was 70.4 ± 31.1, 60.1 ± 22.2, and 60.1 ± 19.0 ml/min/1.73 m(2), respectively (P = 0.16). The incidence of biopsy-proven acute rejection was 1.4%/year in the whole cohort. None of the patients developed polyomavirus-associated nephropathy. The main cause of graft loss (n = 12) was chronic antibody-mediated rejection (n = 6). De novo donor-specific antibodies were detected in 13% of AZA-, 21% of MMF-, and 14% of CsA-treated patients (P = 0.29). CsA monotherapy after 1 year is safe and associated with prolonged graft survival in well-selected renal transplant recipient (ClinicalTrials.gov number: 980654).

Abstract
In this ancillary study of the CONCEPT trial, we studied the role of CsA withdrawal at 3 months (3M) post-transplant on the intensity of epithelial phenotypic changes (EPC, an early marker for kidney fibrogenesis) on the 12 M surveillance biopsy. Although conversion from CsA to sirolimus (SRL) at 3M was reported to have improved mean graft function at 12 M, it did not reduce the score of EPC (1.73 ± 1.15 in the SRL group vs. 1.87 ± 1 in the CsA group, P = 0.61). Acute rejection, which had occurred twice more frequently in SRL-converted patients included here, was associated with 12 M EPC. Interestingly, we observed that the patients durably exposed to CsA and who developed 12 M EPC had a significant progression of blood pulse pressure (pp) from 1 to 6M post-transplantation (Δpp = +12.3 mmHg, P = 0.0035). Pulse pressure at 4, 6, and 9 M and pp progression from 1 to 6M were significantly associated with the development of EPC at 12 M in renal grafts. Logistic regression analysis revealed that a high 6M pp (≥ 60 mmHg) was an independent risk factor for 12 M EPC with an odds ratio of 2.25 per additional 10 mmHg pp (95%CI: 1.14-4.4, P = 0.02) after adjustment with recipient's and donor's age, acute rejection incidence and immunosuppressive regimen. A post hoc analysis of the data collected in the whole population CONCEPT study revealed that pp was significantly higher at 6 months in patients maintained on CsA and that at this time point pp correlated negatively with GFR at 1 year.

Abstract
PURPOSE Post-transplantation lymphoproliferative disorder (PTLD) is associated with significant mortality in kidney transplant recipients. We conducted a prospective survey of the occurrence of PTLD in a French nationwide population of adult kidney recipients over 10 years. PATIENTS AND METHODS A French registry was established to cover a nationwide population of transplant recipients and prospectively enroll all adult kidney recipients who developed PTLD between January 1, 1998, and December 31, 2007. Five hundred patient cases of PTLD were referred to the French registry. The prognostic factors for PTLD were investigated using Kaplan-Meier and Cox analyses. RESULTS Patients with PTLD had a 5-year survival rate of 53% and 10-year survival rate of 45%. Multivariable analyses revealed that age > 55 years, serum creatinine level > 133 μmol/L, elevated lactate dehydrogenase levels, disseminated lymphoma, brain localization, invasion of serous membranes, monomorphic PTLD, and T-cell PTLD were independent prognostic indicators of poor survival. Considering five variables at diagnosis (age, serum creatinine, lactate dehydrogenase, PTLD localization, and histology), we constructed a prognostic score that classified patients with PTLD as being at low, moderate, high, or very high risk for death. The 10-year survival rate was 85% for low-, 80% for moderate-, 56% for high-, and 0% for very high-risk recipients. CONCLUSION This nationwide study highlights the prognostic factors for PTLD and enables the development of a new prognostic score. After validation in an independent cohort, the use of this score should allow treatment strategies to be better tailored to individual patients in the future.

Abstract
Post-transplant diabetes mellitus (PTDM) is a well-known complication in renal transplant recipients (RTRs). While a number of risk factors for PTDM have been identified, the potential impact of pre-transplant dialysis modality on subsequent development of PTDM has not yet been explored. We performed a multicenter retrospective study on 2010 consecutive RTRs who did not have a history of diabetes prior to renal transplantation. PTDM was defined as a need for anti-diabetic therapy in an RTR without a history of diabetes prior to transplantation. Analysis of the risk factors for development of PTDM was performed with respect to pre-transplant dialysis modality. A total of 137 (6.8%) patients developed PTDM; 7% in the hemodialysis group and 6.5% in the peritoneal dialysis (PD) group (p = 0.85). In the multivariate analysis, age (p < 0.001), body mass index (BMI) (p < 0.001), use of tacrolimus (p = 0.002), and rejection episodes (p < 0.001) were identified as independent risk factors for development of PTDM. Patients in the PD group were younger (p = 0.004), had lower BMI (p = 0.07), and were less likely to have a history of hepatitis C (p = 0.007) and autosomal dominant polycystic kidney disease (p = 0.07). Adjustment for these variables did not modify the results. The results of this study suggest that pre-transplant dialysis modality does not have an impact on the subsequent development of PTDM in RTRs.

Abstract
Long-term function of kidney allografts depends on multiple variables, one of which may be the compatibility in size between the graft and the recipient. Here, we assessed the long-term consequences of the ratio of the weight of the kidney to the weight of the recipient (KwRw ratio) in a multicenter cohort of 1189 patients who received a transplant between 1995 and 2006. The graft filtration rate increased by a mean of 5.74 ml/min between the third and sixth posttransplantation months among patients with a low KwRw ratio (<2.3 g/kg; P<0.0001). In this low KwRw ratio group, the graft filtration rate remained stable between 6 months and 7 years but then decreased at a mean rate of 3.17 ml/min per yr (P<0.0001). In addition, low KwRw ratios conferred greater risk for proteinuria, more antihypertensive drugs, and segmental or global glomerulosclerosis. Moreover, a KwRw ratio<2.3 g/kg associated with a 55% increased risk for transplant failure by 2 years of follow-up. In conclusion, incompatibility between graft and recipient weight is an independent predictor of long-term graft survival, suggesting that avoiding kidney and recipient weight incompatibility may improve late clinical outcome after kidney transplantation.

Abstract
BACKGROUND Although cyclosporine maintenance therapy reduces the risk of acute rejection and increases short-term graft survival in renal transplant recipients, its associated nephrotoxicity increases the risk of chronic graft dysfunction. The dose that allows an optimal risk-to-benefit ratio has not been established. METHODS This multicentre study enrolled stable renal allograft recipients receiving cyclosporine and mycophenolate mofetil without corticosteroids in their second year post-transplant. Patients were randomized to a cyclosporine dose targeted to a standard area under the concentration-time curve (AUC)(0-12 h) (usual exposure, n = 104) or 50% of the study standard AUC(0-12 h) (low exposure, n = 108) using a three-point pharmacokinetic sampling. The primary endpoint was the percentage of patients with treatment failure at 24 months (graft loss/acute rejection/nephrotoxicity/>15% serum creatinine level increase). RESULTS Treatment failure was reported in 37 out of 101 (37%) patients in the usual-exposure and 19 out of 106 (18%) patients in the low-exposure groups (P = 0.003). Mean estimated glomerular filtration rate decreased from baseline to 2 years with usual exposure and increased with low exposure (P < 0.001). Mean systolic and diastolic blood pressures were lower with low exposure (P = 0.03 and P = 0.008, respectively). CONCLUSION In renal transplant recipients receiving maintenance therapy without corticosteroids, a minimization strategy using three-point pharmacokinetic sampling to reduce and maintain cyclosporine exposure to 50% of the usual levels is safe and reduces the risk of graft dysfunction.

Abstract
Peritoneal dialysis is commonly used in patients awaiting renal transplantation. The occurrence of delayed graft function is lower in CAPD patients than in hemodialysis patients. This could be explained by the fluid expansion observed in CAPD patients before renal transplantation. Acute allograft rejection incidence is similar in peritoneal dialysis patients and hemodialysis patients. There are controversial data regarding the rate of renovascular thrombosis after renal transplantation in peritoneal dialysis patients. The dialysis modality selected prior to transplantation may explain the rate of renovascular thrombosis in peritoneal dialysis patients. There is an increasing number of patients returning to dialysis after transplantation failure. However, peritoneal dialysis is underused in failed transplant patients. There are few data available regarding the impact of dialysis modality on the outcome of failed transplant patients. Immunosuppression and transplant nephrectomy may affect the outcome of these patients on peritoneal dialysis. The aim of this article is to review the use of peritoneal dialysis in patients awaiting renal transplantation and in failed transplant patients.

Abstract
UNLABELLED This study was carried out to evaluate dialysis initiation of failed transplant patient and the short-term outcome of these patients on dialysis. PATIENTS AND METHOD We conducted a retrospective study of transplanted patients from one centre returning in dialysis after allograft failure. Those patients were transplanted between 31st October 1986 and 3rd March 2004. Patients who experienced allograft failure after 6 months on transplantation were included in the study. RESULTS Among 600 transplanted patients, 92 patients restarted dialysis after allograft failure. Of the 92 failed transplant patients, 69 had a graft survival of more than 6 months. The mean glomerular filtration rate at dialysis initiation was 13+/-5mL per minute. At time of dialysis initiation, patients had mean haemoglobin level at 80.7+/-10.7g/L, and mean serum albumin level at 34+/-6g/L. Urgent dialysis was needed for 39 over 57 patients. Fourteen over 58 patients had no vascular access or peritoneal catheter at dialysis initiation. Fifty-six over 69 patients were treated by haemodialysis. Of the 13 patients treated by peritoneal dialysis 7 were on PD before transplantation whereas 49 over 57 haemodialysis patients were treated by haemodialysis before transplant failure (p<0.05). Immunosuppressive therapy was stopped during the first year following transplantation failure in 52 over 69 patients and 36 over 69 patients underwent transplantectomy. Thirteen over 56 patients presented a least one cardiovascular events after transplantation failure. CONCLUSION Unplanned dialysis initiation is frequent in failed transplant patients, in whom an early dialysis start is probably mandatory.

Abstract
Peritoneal dialysis, like hemodialysis, is a first-line therapy for patients with end-stage renal disease. Progress in medical devices and materials has reduced infectious complications such as peritonitis and catheter exit-site infections and thus decreased morbidity. Peritoneal dialysis fluids are increasingly biocompatible, result in fewer glucose degradation products, protect the peritoneal membrane better and thus improve tolerance. The maintenance of residual renal function, together with better comfort and no pain, help control the fluid and sodium balance. Automated peritoneal dialysis can be performed each night, either autonomously or assisted by a visiting nurse twice a day (to prepare, connect, and disconnect the machine). This treatment can thus be provided to most patients, regardless of their age. Peritoneal dialysis is indicated principally for young people waiting for a kidney transplantation (to preserve their vascular network), elderly patients who wish to remain either at home or in an institution, and patients with cardiac insufficiency, because of the better hemodynamic tolerance. Numerous obstacles, mainly nonmedical, still impede the development of peritoneal dialysis. Patients seen in emergencies start hemodialysis without necessarily receiving any information about peritoneal dialysis. Indeed, neither physicians nor patients receive adequate information.

Abstract
AIMS Polyclonal antilymphocyte globulins (ALGs) are currently used in transplantation, but the sources of interindividual variability of their effect are poorly understood. No pharmacokinetic-pharmacodynamic (PK-PD) study of ALG is available. Moreover, the genetic polymorphism of FcgammaRIIIa, a receptor for the Fc portion of immunoglobulins involved in antibody-dependent cellular cytotoxicity (ADCC), may influence their concentration-effect relationship. METHODS Fourteen kidney transplant patients treated by horse ALG were included in a prospective, noncomparative study. A population two-compartment PK model including a time dependence of the central volume of distribution was developed. Total lymphocyte count was used as biomarker of effect. Concentration-effect data were described using a physiological indirect response model, combining concentration-dependent and -independent inhibitions of lymphocyte input into the circulation. In addition, six kidney transplant patients in whom ALG concentrations were not available were included retrospectively. All patients were genotyped for FCGR3A. RESULTS Both the PK and the PK-PD model described the data satisfactorily and showed high interindividual variability. Asymptotic T(1/2)-alpha and T(1/2)-beta-values were 1.3 and 25 days, respectively. The concentration of ALG leading to a 50% inhibition of lymphocyte input (IC(50)) was lower in FCGR3A-V carriers than in FCGR3A-F/F patients (383 +/- 199 vs. 593 +/- 209 mg l(-1), P = 0.008). CONCLUSIONS This is the first description of the ALG effect on lymphocyte count using PK-PD modelling. Our results show that part of the variability in their concentration-effect relationship may be explained by FcgammaRIIIa genetic polymorphism and therefore that horse ALG may deplete lymphocytes by ADCC.

Abstract
BACKGROUND The French healthcare system offers the possibility of increasing the use of peritoneal dialysis (PD) by involving in patient care nurses who work in the private system. OBJECTIVE This study was conducted to evaluate the impact of a private home-nurse network on one dialysis program. METHODS This was a retrospective study of 239 dialysis patients who started dialysis in our center between 1 January 1998 and 31 December 2003. RESULTS Of these 239 patients, 142 were treated with hemodialysis and 97 with PD during the study period. Among the PD patients, 36 of 97 were treated with assisted PD and 61 of 97 with self-care PD. Assisted-PD patients were older (74 +/- 10 vs 52 +/- 18 years, p < 0.001) and presented more comorbidity (Charlson Comorbidity Index 7 +/- 2.5 vs 4.3 +/- 2.4, p < 0.05) compared with self-care patients. Continuous ambulatory PD was the modality of choice in the assisted group (32/36). Assisted patients were frequently hospitalized (31/36); actuarial survival free of hospitalization at 6 months was 46%. Patients with nurse assistance had a high risk of peritonitis (actuarial survival free of peritonitis: 52% at 1 year). Technique survival was 85% at 6 months and 58% at 1 year. Actuarial patient survival was 90% at 6 months and 83% at 1 year. CONCLUSION Assisted PD enables increased use of PD in incident dialysis patients. However, in view of the comorbidities of the assisted-PD patients, the need for frequent hospitalization has to be taken into account in such a program.

Abstract
Peritonitis is still a frequent complication in peritoneal dialysis patients. Medical guidelines have been established to manage this infection. These guidelines do not provide any information regarding the requirement for hospitalization. The main objective of this study was to evaluate the impact of peritonitis episode on the hospitalization rate and on the hospitalization duration in a centre where peritoneal dialysis patients were hospitalized in case of peritonitis. This was a retrospective study of incident peritoneal patients over a six years period. Among 101 peritoneal dialysis patients 65% were hospitalized. Two hundred and twenty hospital stays were registered. The total duration of hospital stays was 2091 days. The hospitalization rate was 2 per patient and per year, the hospital duration was 19 days per patient per year. Of the 220 hospital stays, 67 (30%) were due to a peritoneal infection. Peritonitis episodes represent 581/2091 (28%) days of hospitalization. The mean duration of hospitalization for peritonitis was 8.7+/-7 days. Among the patients hospitalized for a peritonitis episode, 57% were assisted by a nurse at home to perform their peritoneal dialysis exchanges. Of the 67 peritonitis episodes, 91% were discharged from the hospital without any complication. This study emphases the fact that peritonitis has an important impact on the hospitalization rate and on the hospitalization duration in peritoneal dialysis patients. In an attempt to decrease the rate of hospitalization, educational programs are clearly needed in order to treat more peritonitis without any hospitalization requirement.

Abstract
The glucose side-effects, the main osmotic agent in conventional peritoneal dialysis (PD) solutions, are structural and functional changes of the peritoneal membrane, especially diabetic alterations in the microvasculature. Therefore, hyperpermeability with high small solutes transport and less ultrafiltration necessitates more and more high glucose concentration solutions. Glucose degradation products (PDF) and advanced glycation end-products (AGE) are formed and may induce peritoneal membrane alterations. More biocompatible solutions have to be used with less PDF and physiological pH. Icodextrin containing PD solutions have beneficial effect on sustained ultrafiltration for long dwells in PD, limitating fluid overload common in PD patients above all during peritonitis episodes. Amino acid-based PD solutions contribute to the prevention of malnutrition often observed in the diabetic PD population.

Abstract
Early loss of renal grafts is generally caused by vascular or immunologic complications. We describe two patients who received a kidney transplant from the same donor and lost their grafts during the first posttransplant week. Both cases presented necrotizing graft vasculopathy without inflammatory element. The donor was a 21-year-old woman who regularly used "ecstasy" over a 2-year period. After an extensive work-up to investigate the potential causes of graft loss, we considered the possibility of ecstasy being the cause of these two renal-graft losses.

Abstract
In this retrospective study, we evaluated the impact of automated peritoneal dialysis (APD) on initial graft function after cadaveric renal transplantation. Each patient on APD was matched for donor age, donor serum creatinine, and cold ischemia time with one control patient on HD. The study sample consisted of 67 cases and 67 controls. The rate of delayed graft function--defined as a need for dialysis within the first week following renal transplantation-was 16% in the APD group and 10% in the HD group [p = nonsignificant (NS)]. The proportion of patients with a creatinine clearance below 10 mL/min 6 days after renal transplantation was 7% in the APD group and 3% in the HD group. Of the 67 APD patients, 12 had slow graft function as compared with 13 of the 67 HD patients (p=NS). Weight changes 3 days after transplantation were +2.1% +/- 3.7% of dry weight in HD patients and -0.1% +/- 4.6% of dry weight in APD patients (p < 0.05). The total amount of fluid infused during the surgical procedure was similar in the two groups (55.8 +/- 14.3 mL/kg vs. 60.7 +/- 14.8 mL/kg). Compared with HD, APD was not associated with a lower rate of delayed graft function.

Abstract
The temporal association of tonsillitis and hematuria or proteinuria in IgA nephropathy suggests that there might be a link between the physiological properties of the secondary lymphoid organ that tonsils represent and the mesangial deposition of IgA characteristic of this nephropathy. A number of clinical and ex-vivo data support this hypothesis. One of the earliest was the demonstration of the dimeric nature of mesangial IgA, composed of IgA monomers linked by a J chain, yet lacking the polyIg receptor acquired by secretory IgA during transcytosis through epithelial cells. This molecular structure is that of IgA synthesized in human tonsils, the epithelium of which lacks polyIg receptor. Moreover, tonsils from patients with IgA nephropathy display an abnormal partition of IgG and IgA producing plasma cells associated with a significantly developed web of high endothelial venules. IgA nephropathy could thus be in part related to an alteration of IgA precursors homing in tonsils. Tonsillectomy thus would present the advantage of removing an abnormally functioning source of dimeric IgA. Performed early enough in the course of the renal disease, tonsillectomy could suffice to halt the development of the nephropathy and restore the kidneys to health.

Abstract
The effect of nephronic mass reduction of kidney transplants has not been analyzed specifically in a large cohort. Transplant injuries in cadaver kidney graft may have led to an underestimation of the magnitude of this factor. The aim of this study was to analyze the consequences of kidney mass reduction on transplantation outcome. The weights of 1142 kidney grafts were collected prospectively immediately before grafting. Donors and recipients <15 yr of age, simultaneous kidney/pancreas grafts, and technical failures before day 7 were excluded from the analysis. The analysis was performed on Cockroft-calculated creatinine clearance and proteinuria in 964 patients for whom all of the necessary information was available. This study reports that the smallest kidneys transplanted into the largest recipients (donor kidney weight/recipient body weight [DKW/RBW] <2 g/kg, n = 88) increased their clearance by 2.38 ml/min every month for 6 mo (P < 0.0001) and by 0.27 ml/min thereafter (P < 0.0001). Conversely, creatinine clearance did not change for the largest kidneys transplanted into the smallest recipients (DKW/RBW ratios >/=4 g/kg). Next, using a Cox model analysis, it was shown that the risk of having a proteinuria >0.5 g/kg was significantly increased for the low DKW/RBW ratios <2 g/kg with 50% of patients having a proteinuria, compared with DKW/RBW ratios >/=4 g/kg (P < 0.001). In cadaver transplant recipients, graft mass has a rapid impact on graft filtration rate and proteinuria. Avoiding major kidney/recipient inadequacy should have a significant influence on long-term transplant function.

Abstract
BACKGROUND Two hundred and forty cadaveric renal transplant recipients given anti-thymocyte globulin (Thymoglobulin) as induction immunotherapy were followed up prospectively to review safety and efficacy. METHODS The median number of infusions was 10 [2-21] with a cumulative dose of 8.8 mg/kg [2.0-23.2 mg/kg]. During the fortnight following transplantation, 231 patients (96%) received a calcineurin inhibitor; all patients were given steroids and azathioprine or mycophenolate mofetil. At 1 yr, 60% of patients were on tripletherapy, 38% on bitherapy, and 2% on monotherapy; 20% had discontinued steroids. RESULTS Tolerance was excellent with no cases of anaphylaxis. The commonest adverse event was fever (55%). Eighteen patients developed serum sickness on median day 11 [10-14]. Seven patients had thrombocytopenia; six patients had severe neutropenia. All of these adverse events recovered spontaneously. The overall incidence of delayed graft function was 24%. At 1 yr patient and graft survival were 98 and 95%, respectively, and creatinine was 135 +/- 43 micromol/L. Clinically suspected and biopsy-proven acute rejection were observed in 65 patients (27%) and 34 patients (14%), respectively. There were 62 non-cytomegalovirus (CMV) infections (two fatal) and 81 episodes of CMV infections. Eight malignancies were reported; two possibly related to immunosuppression. CONCLUSIONS These results demonstrate that anti-thymocyte globulin has a safety profile with good tolerability and excellent efficacy.

Abstract
Recurrence of crescentic necrotizing glomerulonephritis after renal transplantation is rare. Successful renal transplantation in patients with antineutrophil cytoplasmic autoantibody (ANCA) glomerulonephritis has been reported. The presence of ANCA at transplantation does not appear to increase the rate of relapse after kidney allografting. Therapy with cyclophosphamide and corticoids usually is effective. We report a case of recurrent perinuclear ANCA crescentic necrotizing glomerulonephritis immediately after renal transplantation that was treated successfully by cyclophosphamide, plasma exchange, and intravenous polyvalent immunoglobulin.

Abstract
BACKGROUND Hypertension and hyperuricaemia are common side-effects of cyclosporin A (CsA) treatment in renal transplant recipients. While it is well established that the calcium channel blocker amlodipine can control CsA-induced hypertension effectively in this patient population, recent evidence suggests amlodipine might also reduce hyperuricaemia. The present study was designed to compare the effects of the calcium channel blocker amlodipine (5-10 mg/day) and the beta-adrenoceptor antagonist tertatolol (5-10 mg/day) on CsA-induced hyperuricaemia in post-renal transplant recipients with hypertension. METHODS Forty-eight hypertensive renal transplant recipients on a stable dose of CsA were randomized in a double-blind, parallel-group manner to receive either amlodipine (n = 24) or tertatolol (n = 24) for 60 days. The primary outcome measure was the change from baseline in serum uric acid concentration. Secondary analyses of efficacy were based on changes in renal function and blood pressure. RESULTS Amlodipine significantly decreased serum uric acid levels from 483 +/- 99 to 431 +/- 110 microM/l (P < 0.001), while tertatolol significantly increased uric acid from 450 +/- 98 to 476 +/-84 microM/l (P = 0.006). Amlodipine also significantly increased glomerular filtration rate (P = 0.0048) and the clearance rate of uric acid (P = 0.023) and it reduced the fractional proximal tubular reabsorption of sodium (P < 0.001), compared with tertatolol. Renal plasma flow and filtered fraction were unaffected by both treatments, as was trough CsA blood concentration. Amlodipine lowered systolic blood pressure to a significantly greater extent than did tertatolol (P = 0.007). The time-dependent profile of diastolic blood pressure did not differ significantly between treatment groups. Both drugs were well tolerated. CONCLUSIONS Amlodipine could be more appropriate than tertatolol for CsA-induced hypertension and hyperuricaemia in renal transplant recipients.

Abstract
UNLABELLED VIROLOGICAL ASPECTS: Human polyomaviruses (BK virus and JC virus), together with simian polyomaviruses (SV40 virus) share 75% of genomic homology. Their in vivo and in vitro genomes vary. Molecular analyses have identified several genotypes, some of which appear related to the development of viral diseases. Genomic modifications of the regulation area might provide the BKv with a pathogenic aspect thus enhancing the induction of tubulo-interstitial nephropathies in renal transplant recipients. EPIDEMIOLOGY Human polyomaviruses are ubiquitous and exhibit a sero-prevalence of 60 to 80% in adults. Following a primary infection via the respiratory tract in childhood, these viruses are diffused in the blood using the B-lymphocytes during their latent stage in the urogenital tract. The reactivation that occurs after several years is asymptomatic and urinary excretion of BKv is observed in 4 to 6% of immunocompetent patients. PATHOGENIC POTENTIAL Human polyomaviruses have a cytopathogenic effect on the urothelium and epithelium of renal transplant recipients. Infection by BKv may provoke hemorrhagic cystitis or urethral stenosis. The JCv is the cause of progressive multifocal leuko-encephalitis. The BKv (and less frequently the JCv) is responsible for tubulo-interstitial nephritis possible leading to renal transplant loss. They also have an oncogenic effect and their implication in the origin of tumours is the subject of many studies.

Abstract
TO IMPROVE THERAPEUTIC MANAGEMENT: The aim is the early detection of polyomavirus infection, before the onset of tubulo-interstitial nephritic lesions, and to reduce viral replication. AT THE STAGE OF POLYOMAVIRUS INFECTION: Treatment relies on the reduction of immunosuppression. Efficacy is controlled by monitoring the decoy cells in the urine and the detection and quantification of the DNA of polyomaviruses in the plasma and urine. AT THE STAGE OF POLYOMAVIRUS DISEASE: The aim is to reduce the viral replication by further decreasing immunosuppression to stabilize renal function and avoid graft rejection. When signs of rejection and viral infection co-exist, cidofovir could be a therapeutic alternative. However, the use of cidofovir remains in the field of clinical research and requires the further development of therapeutic protocols.

Abstract
A THREAT FOR RENAL ALLOGRAFT: Human polyomavirus infections (BK virus, JC virus), known for the past 30 years, were considered as common in renal transplantation until the recently reported studies describing the responsibility of BKv (and less JCv) in the occurrence of tubulo-interstitial nephritis in around 5% of renal transplant recipients, with worsening of the renal function leading to graft failure in 10 to 45% of infected patients. Their description coincided with the use of new immunosuppressors (tacrolimus and mycophenolate mofetil) without, however, their responsibility clearly incriminated. EARLY DIAGNOSIS FOR EFFICIENT TREATMENT: The presence of cells infected by the polyomavirus ("decoy cells") in the urine and the detection of BKv or JCv DNA by PCR in the plasma and urine are viral replication markers which strongly suggest the possibility of a polyomavirus nephropathy. TWO CLINICAL VARYING FORMS: Polyomavirus infection is frequent and often asymptomatic. The diagnosis requires the detection of large nucleus "decoy cells" in fresh urine. Polyomavirus renal allograft disease is characterised by the association of decoy cells and renal failure related to a tubulo-interstitial nephropathy and the presence of DNA of the virus in the plasma. The diagnosis requires identification of intra-nuclear viral inclusions in epithelial cells using immunohistochemistry, in situ hybridisation, or electron microscopy techniques. A DIFFICULT DIAGNOSIS: Confusion between interstitial nephritis and acute cellular rejection is the major risk leading to therapeutic error. Risk factors include over-immunosuppression and/or treatment of rejection episodes which could increase viral replication as well as the emergence of mutant BKv strains at the origin of tubulo-interstitial nephritis, leading to acute and chronic dysfunction of the renal transplantation.

Abstract
Acute graft rejection remains a major problem in renal transplant recipients, and there is no consensus on the optimal immunosuppressive strategy. Immunoprophylaxis with Thymoglobulin or basiliximab has significantly reduced the incidence of acute rejection episodes and graft loss following kidney transplantation. This open, randomized, multicenter study investigated the efficacy and tolerability of basiliximab (20mg day 0-day 4) plus early cyclosporine from day 0 (n = 50) compared with Thymoglobulin plus delayed cyclosporine (n = 50) in adult kidney transplant patients. In addition, all patients received steroids and mycophenolate mofetil (MMF) at standard doses from day 0. Patient and graft survival rates at 12 months were 98 and 94% in the basiliximab group, respectively, compared with 100 and 96% in the Thymoglobulin' group. The incidences of biopsy-confirmed acute rejection (8.0% in each group) and treatment failure (14% in the basiliximab group vs. 8% in the Thymoglobulin group) were comparable in the two groups. There was a non-significant tendency to more dialysis (14 vs. 6%), and fewer cytomegalovirus (CMV) infections (p = 0.005) in the basiliximab group, but the percentage of clinical CMV was not different between the two groups (6 vs. 12%). Both strategies give excellent results, despite the differences in patterns, in nonhyperimmunized patients receiving their first cadaveric renal allograft.
