Kidney transplantation restores fertility in patients with end-stage renal disease, with many successful pregnancies after kidney transplantation being reported. However, there are little data regarding pregnancy in women transplanted under modern-era desensitisation protocols that utilise rituximab, plasma exchange and intravenous immunoglobulin, including ABO-incompatible transplants. Pregnancies in ABO-incompatible recipients can pose new challenges from an immunological perspective. Here, we report a case of successful pregnancy using in vitro fertilisation, in a renal transplant recipient who underwent desensitisation two years prior, that included use of rituximab and plasma exchange to receive an ABO-incompatible transplant from her husband and subsequent father of the baby. We believe this was the first case of successful pregnancy after ABO-incompatible kidney transplantation in Australia and New Zealand. This case also highlights the difficulties faced in conception following transplantation and demonstrates that in vitro fertilisation utilising ovulation induction can be successfully utilised for conception in this cohort. This recipient also had gestational diabetes, worsening renal function and preterm delivery which are important complications often seen in pregnancies of solid organ transplant recipients.

Kidney transplantation is the most common solid organ transplant and the best current therapy for end-stage kidney failure. However, with standard immunosuppression, most transplants develop chronic dysfunction or fail, much of which is due to chronic immune injury. Tregs are a subset of T cells involved in limiting immune activation and preventing autoimmune disease. These cells offer the potential to provide tolerance or to allow reduction in immunosuppression in kidney transplants. The importance of Tregs in kidney transplantation has been shown in a number of seminal mouse and animal studies, including those with T cell receptors (TCRs) transgenic Tregs (TCR-Tregs) or Chimeric Antigen Receptor (CAR) Tregs (CAR-Tregs) showing that specificity increases the potency of Treg function. Here we outline the animal and human studies and clinical trials directed at using Tregs in kidney transplantation and other tolerance settings and the various modifications to enhance allo-specific Treg function in vivo and in vitro.

Renal transplantation is the treatment of choice for patients with end-stage renal disease. While transplantation improves the quality of life and reduces the mortality risk for most patients when compared with maintenance dialysis, it introduces significant morbidity associated with induction and maintenance immune suppression. Sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, is frequently used as a second-line maintenance immunosuppressive agent in solid organ transplant recipients. Sirolimus may, however, have adverse vascular effects and has previously been shown to induce endothelial cell dysfunction and impaired nitric oxide production in vitro. Sirolimus-eluting coronary artery stents have been associated with rare reports of severe coronary artery vasospasm; however, systemic sirolimus therapy has not previously been associated with vasospastic complications.

A 21-year-old female with end stage renal disease underwent a non-related renal transplantation from a deceased pregnant donor. The recipient had a negative serum pregnancy test prior to her surgery. However postoperatively, a rise in her serum human chorionic gonadotrophin (hCG) level, which lasted several days, was documented. Solid organ transplantation is known to transmit various infections, malignant cells and antibodies from donor to recipient but no previous reports described transmission of hCG. This case report highlights the importance of considering this possibility when managing post-transplantation hormonal disturbances. Further research is warranted to evaluate the different mechanisms through which transmission occurs between donor and recipient.

Long-term survival in patients with pancreatic ductal adenocarcinoma (PDAC) is limited. Consequently, solid organ transplantation in PDAC patients is usually not considered. This is the first case report of kidney transplantation (KT) in a 57-year-old female patient after extended multivisceral resection for PDAC of the distal pancreas who had developed end-stage renal disease (ESRD) due to toxic kidney damage by chemotherapy. 13,5 years after initial PDAC-operation and 3 years after KT the patient remains in a good general health condition with sufficient function of the kidney allograft without local tumor recurrence or distant metastasis.

Cmv Reactivation

Introduction: Cytomegalovirus (CMV) reactivation occurs in seronegative patients after solid organ transplantation (SOT) particularly from seropositive donors and can be lethal. Generation of CMV-specific T cells helps to prevent CMV reactivation. Therefore, we initiated a clinical phase I CMVpp65 peptide vaccination trial for seronegative end-stage renal disease patients waiting for kidney transplantation. Methods: The highly immunogenic nonamer peptide NLVPMVATV derived from CMV phosphoprotein 65(CMVpp65) in a water-in-oil emulsion (Montanide™) plus imiquimod (Aldara™) as an adjuvant was administered subcutaneously four times biweekly. Clinical course as well as immunological responses were monitored using IFN-γ ELISpot assays and flow cytometry for CMV-specific CD8+ T cells. Results: Peptide vaccination was well tolerated, and no drug-related serious adverse events were detected except for Grade I–II local skin reactions. Five of the 10 patients (50%) mounted any immune response (responders) and 40% of the patients presented CMV-specific CD8+ T cell responses elicited by these prophylactic vaccinations. No responders experienced CMV reactivation in the 18 months post-transplantation, while all non-responders reactivated. Conclusion: CMVpp65 peptide vaccination was safe, well tolerated, and clinically encouraging in seronegative end-stage renal disease patients waiting for kidney transplantation. Further studies with larger patient cohorts are planned.

Introduction: Transplantation is the optimal management for patients with end-stage renal disease. In Ethiopia, the first national kidney transplantation center was opened at St. Paul’s Hospital Millennium Medical College in September 2015. The aim of this study was to explore providers’ views and experiences of the past to present at this center. Methods: A qualitative study design was employed from 1st November to 15th December, 2019. To ensure that appropriate informants would provide rich study data, 8 health care providers and top management members were purposefully chosen for in-depth interviews. A maximum variation sampling method was considered to include a representative sample of informants. Interviews were digitally audio-recorded, and transcribed verbatim. Transcribed data was coded and analyzed using Qualitative Data Analysis (QDA) Minor Lite software and Microsoft-Excel. Result: The participants (5 males and 3 females) approached were from different departments of the renal transplant center, and the main hospital. Eight main themes and 18 sub-themes were generated initially from all interviews totaling to 109 index codes. Further evaluation and recoding retained 5 main themes, and 14 sub-themes. The main themes are; challenges experienced during and after launching the center, commitment, sympathy and satisfaction, outcomes of renal transplant, actions to improve the quality of service, and how the transplant center should operate. Providers claim that they discharge their responsibilities through proper commitment and compassion, paying no attention to incentive packages. They also explained that renal transplantation would have all the outcomes related to economic, humanistic and clinical facets. Conclusion and Recommendation: A multitude of challenges were faced during and after the establishment of the first renal transplant center in Ethiopia. Providers discharge their responsibility through a proper compassion for patients. Concerned stakeholders should actively collaborate to improve the quality of renal transplant services in the center.

AbstractErectile dysfunction (ED) is a major global health burden commonly observed in patients with end-stage renal disease (ESRD). Although renal transplantation improves the problem in some patients, it persists in ≈20–50% of recipients. Studies regarding the effects of kidney transplantation on ED present contradictory findings. We performed a systematic review to summarise the effects of kidney transplantation on ED. A systematic literature search was performed across PubMed, Cochrane, and Scopus databases in April 2020. We included all prospective studies that investigated the pre and posttransplant international index of erectile function (IIEF-5) scores in recipients with ED. Data search in PubMed and Google Scholar produced 1326 articles; eight were systematically reviewed with a total of 448 subjects. Meta-analysis of IIEF-5 scores showed significant improvements between pre and post transplantation. Our findings confirm that renal transplantation improves erectile function. Furthermore, transplantation also increases testosterone level. However, the evidence is limited because of the small number of studies. Further studies are required to investigate the effects of renal transplantation on erectile function.
