Communion by extension : discrepancies between policy and practice

The growing practice of Communion by Extension was given formal authorisation by the Church of England General Synod in 2000 with the expectation that it would be used in particular circumstances, including explicitly the rural multi-church benefice. This paper reviews the historical origins of the practice of Communion by Extension and clarifies the intentions of the authorisation given in 2000. Then the intentions of the 2000 authorisation are compared and contrasted with current parochial practice within one English diocese. Considerable divergence is found. Five main themes are identified and discussed: the relationship between worship and mission; the pressures on clerical time; sacramental self-sufficiency; the value given to familiarity; and the choice between reservation and congregationalism

Combining transplant professional's psychosocial donor evaluation and donor self-report measures to optimise the prediction of HRQoL after kidney donation:an observational prospective multicentre study

OBJECTIVES: Living donor kidney transplantation is currently the preferred treatment for patients with end-stage renal disease. The psychosocial evaluation of kidney donor candidates relies mostly on the clinical viewpoint of transplant professionals because evidence-based guidelines for psychosocial donor eligibility are currently lacking. However, the accuracy of these clinical risk judgements and the potential added value of a systematic self-reported screening procedure are as yet unknown. The current study examined the effectiveness of the psychosocial evaluation by transplant professionals and the potential value of donor self-report measures in optimising the donor evaluation. Based on the stress-vulnerability model, the predictive value of predonation, intradonation and postdonation factors to impaired longer term health-related quality of life (HRQoL) of kidney donors was studied. DESIGN: An observational prospective multicentre study. SETTING: Seven Dutch transplantation centres. PARTICIPANTS: 588 potential donors participated, of whom 361 donated. Complete prospective data of 230 donors were available. Also, 1048 risk estimation questionnaires were completed by healthcare professionals. METHODS: Transplant professionals (nephrologists, coordinating nurses, social workers and psychologists) filled in risk estimation questionnaires on kidney donor candidates. Furthermore, 230 kidney donors completed questionnaires (eg, on HRQoL) before and 6 and 12 months after donation. PRIMARY AND SECONDARY OUTCOME MEASURES: HRQoL, demographic and preoperative, intraoperative and postoperative health characteristics, perceived support, donor cognitions, recipient functioning and professionals risk estimation questionnaires. RESULTS: On top of other predictors, such as the transplant professionals’ risk assessments, donor self-report measures significantly predicted impaired longer term HRQoL after donation, particularly by poorer predonation physical (17%–28% explained variance) and psychological functioning (23%). CONCLUSIONS: The current study endorses the effectiveness of the psychosocial donor evaluation by professionals and the additional value of donor self-report measures in optimising the psychosocial evaluation. Consequently, systematic screening of donors based on the most prominent risk factors provide ground for tailored interventions for donors at risk

Early Steroid Withdrawal Compared With Standard Immunosuppression in Kidney Transplantation - Interim Analysis of the Amsterdam-Leiden-Groningen Randomized Controlled Trial

BACKGROUND: The optimal immunosuppressive regimen in kidney transplant recipients, delivering maximum efficacy with minimal toxicity, is unknown. METHODS: The Amsterdam, LEiden, GROningen trial is a randomized, multicenter, investigator-driven, noninferiority, open-label trial in 305 kidney transplant recipients, in which 2 immunosuppression minimization strategies-one consisting of early steroid withdrawal, the other of tacrolimus minimization 6 months after transplantation-were compared with standard immunosuppression with basiliximab, corticosteroids, tacrolimus, and mycophenolic acid. The primary endpoint was kidney function. Secondary endpoints included death, primary nonfunction, graft failure, rejection, discontinuation of study medication, and a combined endpoint of treatment failure. An interim analysis was scheduled at 6 months, that is, just before tacrolimus minimization. RESULTS: This interim analysis revealed no significant differences in Modification of Diet in Renal Disease between the early steroid withdrawal group and the standard immunosuppression groups (43.2 mL/min per 1.73 m2 vs 45.0 mL/min per 1.73 m2, P = 0.408). There were also no significant differences in the secondary endpoints of death (1.0% vs 1.5%; P = 0.737), primary nonfunction (4.1% vs 1.5%, P = 0.159), graft failure (3.1% vs 1.5%, P = 0.370), rejection (18.6% vs 13.6%, P = 0.289), and discontinuation of study medication (19.6% vs 12.6%, P = 0.348). Treatment failure, defined as a composite endpoint of these individual secondary endpoints, was more common in the early steroid withdrawal group (P = 0.027), but this group had fewer serious adverse events and a more favorable cardiovascular risk profile. CONCLUSIONS: Based on these interim results, early steroid withdrawal is a safe short-term immunosuppressive strategy. Long-term outcomes, including a comparison with tacrolimus minimization after 6 months, will be reported in the final 2-year analysis

Wound morbidity after kidney transplant

Wound morbidity is an important surgical complication after kidney transplant. To assess risk factors for postoperative wound complications and the impact of such complications on outcomes of kidney transplant. Retrospectively, 108 consecutive kidney transplant patients between January 2010 and December 2010 were included in the analysis. Wound morbidity was defined as a surgical site infection or symptomatic lymphocele requiring intervention. Patient, donor, and surgical characteristics were reviewed. Eight lymphoceles and 5 surgical site infections occurred in 12 patients. Risk factors for wound complications were recipient's age (P <.01), body mass index (P=.01), urinary tract infection (P=.01), and prolonged postoperative wound drainage (P=.047). Wound morbidity did not increase the incidence of delayed graft function, acute rejection, graft failure, or mortality. Obesity, recipient's age, urinary tract infection, and prolonged wound drainage are risk factors for wound-related complications. Graft and patient survival rates are comparable between patients with and without wound-related complication

Transplant nephrectomy: what are the surgical risks?

Whether or not to remove a failed renal graft has been the subject of much debate. One reason for a cautious approach to graft removal is its high morbidity and mortality rates. We analyzed the morbidity, mortality, and risk factors of transplant nephrectomy at our center. We included 157 cases of transplant nephrectomy in 143 patients, performed between January 2000 and May 2012 at the Academic Medical Center, Amsterdam. Patient data were collected retrospectively. A total of 32 surgical complications occurred after transplant nephrectomy (20%) and 16 patients needed surgical re-intervention (10%). Hemorrhage and infection are the most frequent causes of surgical complications (14%). The mortality rate was 3.2%. There were no significant differences in characteristics and timing of transplant nephrectomy between the group with surgical complications and the group without. A total of 59 re-transplantations were performed in 57 patients (38%). Transplant nephrectomy is associated with high morbidity and mortality rates. We found no significant risk factors for surgical complications following transplant nephrectomy and no significant association between timing of transplant nephrectomy and surgical complications. Steps to reduce these complications need further investigatio

B cells in cluster or in a scattered pattern do not correlate with clinical outcome of renal allograft rejection

BACKGROUND: The role of CD20+ B cells in renal allograft rejection has been reappreciated. Importantly, recent studies suggest a relation between CD20+ B cell aggregates and poorer clinical outcome. In the present study, we attempted to confirm these early reports in a tightly controlled patient population and to differentiate between scattered infiltrates and clusters of B cells. METHODS: Fifty-four biopsies from renal transplant recipients with acute rejection were immunostained for CD20, CD3, and C4d. All patients received similar immunosuppressive therapy. Response to therapy was defined as a decrease in serum creatinine level within 2 weeks to 125% or less of the value before the clinically diagnosed episode of allograft rejection. Late clinical outcome was defined in creatinine clearance between 8 and 12 months after the episode of acute rejection or in graft failure. RESULTS AND CONCLUSION: A significant correlation was observed between interstitial infiltrates of CD20+ cells and CD3+ cells (r=0.720, P <0.001) suggesting that if B-cell infiltrates are present during rejection, they occur with T-cell infiltrates in a concurrent fashion. In contrast to previous reports, no relation was found between the number of CD20+ cells, in aggregates or in a scattered interstitial pattern, and response to conventional therapy. Remarkably, CD3+T cell aggregates did predict a favorable renal outcom

Everolimus-treated renal transplant recipients have a more robust CMV-specific CD8+ T-cell response compared with cyclosporine- or mycophenolate-treated patients

In renal transplant recipients, mammalian target of rapamycin (mTOR) inhibitors have been reported to protect against cytomegalovirus (CMV) disease. Here, we questioned whether mTOR inhibitors specifically influence human CMV-induced T-cell responses. We studied renal transplant recipients treated with prednisolone, cyclosporine A (CsA), and mycophenolate sodium (MPS) for the first 6 months after transplantation followed by double therapy consisting of prednisolone/everolimus, which is an mTOR inhibitor (P/EVL; n=10), prednisolone/CsA (P/CsA; n=7), or prednisolone/MPS (P/MPS; n=9). All patients were CMV-IgG positive before transplantation. CMV reactivation was detectable in the first 6 months after transplantation and not thereafter. None of the patients included in this study suffered from CMV disease. Both CD27CD8 and CD27CD28CD4 effector-type T-cell counts, known to be associated with CMV infection, were measured before transplantation and at 6 and 24 months after transplantation. Additionally, we determined both number and function of CMV-specific CD8 T cells at these time points. The number of total CD8 T cells, CD27CD8 T cells, and CD28CD4 T cells increased significantly after switch to therapy with P/EVL but not after switch to P/CsA or P/MPS. Specifically, CMV-specific CD8 T-cell counts significantly increased after switch to therapy with P/EVL. Furthermore, the mTOR inhibitor sirolimus strongly inhibited alloresponses in vitro, whereas it did not affect CMV-specific responses. We observed a significant increase in (CMV-specific) effector-type CD8 and CD4 T-cell counts in everolimus-treated patients. These findings may at least in part explain the reported low incidence of CMV-related pathology in everolimus-treated patient

CXCR5+CD4+ follicular helper T cells accumulate in resting human lymph nodes and have superior B cell helper activity

Although many relevant immune reactions are initiated in the lymph nodes, this compartment has not been systematically studied in humans. Analyses have been performed on immune cells derived from tonsils, but as this tissue is most often inflamed, generalization of these data is difficult. Here, we analyzed the phenotype and function of the human CD4(+) T-cell subsets and lineages in paired resting lymph node and peripheral blood samples. Naive, central memory cells and effector memory cells as well as Th1, Th2, Th17 and Treg cells were equally represented in both compartments. On the other hand, cytotoxic CD4(+) T cells were strikingly absent in the lymph nodes. CXCR5(+)CD4(+) T cells, representing putative follicular Th (Tfh) cells were over-represented in lymph nodes and expressed higher levels of Tfh markers than their peripheral blood counterparts. Compared with the circulating pool, lymph-node-derived CXCR5(+)CD4(+) T cells were superior in providing help to B cells. Thus, functionally competent Tfh cells accumulate in resting human lymph nodes, providing a swift induction of naive and memory antibody responses upon antigenic challeng

Maintenance immunosuppressive therapy with everolimus preserves humoral immune responses

While the guidelines for vaccination in renal transplant recipients recommend the use of pneumococcal polysaccharide (PPS) and tetanus toxoid (TT), their efficacy in immunocompromised renal transplant recipients is not known. Here we tested the effect of everolimus on immune responses after vaccination by measuring the capacity of 36 stable renal transplant recipients to mount cellular and humoral responses after vaccination. Twelve patients in each treatment arm received immunosuppressive therapy consisting of prednisolone (P) plus cyclosporine (CsA), mycophenolate sodium (MPA), or everolimus. Patients were vaccinated with the T-cell-dependent antigens immunocyanin and TT, and the T-cell-independent PPS. Treatment with CsA partially inhibited and MPA completely abolished the capacity to mount a primary humoral response, whereas everolimus left this largely intact. Recall responses were inhibited by MPA only. All drug combinations inhibited cellular responses against TT. In patients treated with MPA, B-cell numbers were severely reduced. Thus, combined with P, treatment with MPA completely disturbed primary and secondary humoral responses. Everolimus or CsA allowed the boosting of T-cell-dependent and -independent secondary humoral responses. Treatment with everolimus allowed a primary response.
