This is a case of a 56-year-old man with Castleman disease (CD) who improved after kidney transplantation (KTP). CD is an uncommon lymphoproliferative disorder that was found incidentally on biopsy during dialysis in the current patient and was followed up without further treatment. However, the lesion showed improvement after KTP. Therefore, active KTP can be considered even if CD is one of the lymphoproliferative disorders that can occur as a complication after KTP.

Angiotensin II type 1 receptor (AT1R) antibodies directly injure endothelial and vascular smooth muscle cells by activating transcription factors associated with proinflammatory responses. Previous studies have shown that AT1R antibodies are associated with allograft rejection and decreased graft survival in kidney transplantation. Development of enzyme-linked immunosorbent assay has facilitated semiquantitative detection of AT1R antibodies. Assessing AT1R antibodies along with donor specific human leukocyte antigen antibodies may have potential to identify patients with possible risk for allograft injury and improve overall outcomes. In this review, we summarize recent clinical studies about AT1R antibodies in kidney transplantation and provide perspectives for future research area.

Lymphoproliferative disorder in a posttransplant setting has emerged as a difficult problem in kidney transplantation (KT). Lymphoma involving adnexa of the eye has rarely been reported due to scarcity of lymphoreticular tissue in the ocular area. This report presents a case of a 37-year-old KT recipient who was diagnosed with conjunctival mucosa-associated lymphoid tissue lymphoma with a chief complaint of seeing black spots. Unlike other post-transplant lymphoproliferative diseases associated with the Epstein-Barr virus (EBV) reactivation via immunosuppression, the lesion was not related to the virus. The patient received radiotherapy with concomitant conversion from the tacrolimus to the sirolimus. Overall, the results presented herein indicate lymphoma may be an important differential diagnosis when KT recipients complain of ocular discomfort.

Detection of significant alloimmune response, which affects graft function and survival by effective immune monitoring, is critical for treatment decision making. However, there is no consensus regarding immune monitoring (IM) for kidney transplantation (flow KT) in Korea. The IM protocol may be affected by the level of immunological risk, the methods of desensitization and the availabilities of resources such as laboratory support and cost of tests. Questionnaire surveys designed to identify the current practices regarding immune monitoring of KT among transplant clinicians and clinical pathologists in Korea and eventually provide a basis for the establishment of harmonized immune monitoring guidelines in KT were administered as part of a Korean Society for Transplantation Sponsored Research Project. The survey results revealed significant variations in IM protocols and interpretation of tests affecting treatment decisions between institutes. Moreover, the results revealed a need to expand the histocompatibility tests into high resolution HLA typing in multiple loci and non-HLA antibody tests that facilitate the epitope analysis and eventually virtual crossmatching. The results of the questionnaire survey from clinical pathologists are addressing the urgent need for the standardization of interpretation and harmonization of results reporting in single antigen bead based HLA antibody identification. Finally, communication between clinicians and clinical pathologists to meet the clinical expectations regarding various immune monitoring tests is needed.

Pregnancy following heart transplantation is a high-risk condition, requiring adequate maintenance of immunosuppressive drugs that enable proper graft function for optimal maternal and fetal outcomes. Here, we present the first case of successful child delivery in a patient who underwent heart transplantation in Korea. The 35-year-old female patient had become pregnant at 4 years after heart transplantation. The pregnancy progressed uneventfully, and the infant was healthy.

Induction therapy with basiliximab is widely administered after kidney transplantation to prevent acute rejection. Herein, we report a case of non-cardiogenic pulmonary edema induced by basiliximab. To the best of our knowledge, such case has not been reported to date in Korea. A 54-year-old man with polycystic kidney disease received kidney transplantation. As induction therapy, he was prescribed basiliximab. On day 4, the second dose of basiliximab was administered. The patient complained of acute hypoxia 23 hours later, which led to circulatory collapse. He was discharged 3 weeks later with stable renal function. Pulmonary edema was presumed to have been caused by increased pulmonary capillary permeability. A possible hypothesis for this event occurring after the second basiliximab injection is steroid-related effects. Non-cardiogenic pulmonary edema is a complication that might occur after basiliximab induction therapy. Physicians should be aware of this potentially life-threatening complication.

A 38-year-old man, who underwent a second kidney transplantation (KT), was admitted because of antibody-mediated rejection (AMR) complicated by BK virus-associated nephropathy (BKVAN). He was placed on hemodialysis at the age of 24 years because of membranoproliferative glomerulonephritis. At the age of 28 years, he underwent a living donor KT from his father; however, 1 year after the transplantation, he developed a recurrence of the primary glomerular disease, resulting in graft failure 2 years after the first KT. Ten years later, he received a deceased-donor kidney with a B-cell-positive-cross-match. He received 600 mg of rituximab before the KT with three cycles of plasmapheresis and immunoglobulin (0.5 g/kg) therapy after KT. During the follow-up, the first and second allograft biopsies at 4 and 10 months after KT revealed AMR with a recurrence of primary glomerular disease that was reclassified as C3 glomerulonephritis (C3GN). He received a steroid pulse, rituximab, plasmapheresis, and immunoglobulin therapies. The third allograft biopsy demonstrated that the BKVAN was complicated with AMR and C3GN. As the azotemia did not improve after repeated conventional therapies for AMR, one cycle of bortezomib (1.3 mg/m²×4 doses) was administered. The allograft function stabilized, and BK viremia became undetectable after 6 months. The present case suggests that bortezomib therapy may be applicable to patients with refractory AMR, even in cases complicated with BKVAN.

BACKGROUND: Bortezomib has been used to treat antibody-mediated rejection (AMR) that usually develops after kidney transplantation (KT). Although it has been used in various clinical situations, it is difficult to precisely define how the drug affects the clinical course. We used bortezomib to treat eight cases of AMR that developed immediately following KT in patients who were resistant to conventional treatment. METHODS: Eight cases of refractory AMR that developed immediately after KT were treated with bortezomib on days 1, 4, 8, and 11. RESULTS: The resolution rate was 75%, and the 2-year rejection-free survival rate was 83%. Six cases underwent immunologically high-risk KT. Six recovering patients exhibited clinical improvement within 2 weeks of the first dose of bortezomib and recovered completely within 2 months. The effects of bortezomib seemed to be prolonged; only one additional rejection episode was observed. The two failed patients never exhibited any clinical improvement and progressed aggressively to graft failure soon after transplantation. Their donor specific anti-human leukocyte antigen antibody were sustained at high levels. CONCLUSIONS: Bortezomib is an effective rescue therapy in patients with AMR that developed immediately after KT.

Deceased organ donation in Korea has increased steadily after legislation of transplantation law. Since last year, however, several obstacles resulting in a decrease in organ donation have been experienced. Among them, the reduced reporting of potential brain death from large size hospitals and reduced consent rate of medically available deceased donors are two main hurdles. The consent rate of organ donation was 41.9% in 2017 but has dropped to approximately 10% than 2016. Other strong family members overrode approximately 10% of donations initially consented by their next of kin. In addition to the medical points, difficulties in labor shortage are being experienced during donor management, testing and organ recovery in the hospital. Some end stage patients who are candidates as organ donor give up further management and decide to withdrawing life sustaining treatment, which deprive the chance of donation. Moreover, the national mortality rate of cerebrovascular and traffic accidents, which occupy a major part of brain death, have decreased over the recent 10 years. All of these events can cause a decrease in brain death development so it is important to find solutions to overcome all of them. Revising transplant law and donation system should be led by government. Efforts to increase the consent rate, procurement rate, and transplant rate and decrease the organ discard rate are all the responsibility of the medical team. Public awareness and a positive attitude towards organ donation are the most important basic requirements for increasing organ donation. A comprehensive task force team to overcome all of these problems is requested.
