BACKGROUND: Desensitization therapy may enable the patient to get allograft in sensitized recipient or solve the organ shortage in ABO-incompatible relationship in kidney transplantation (KT). However, the graft outcome and morbidity remains unclear. METHODS: We retrospectively analyzed 845 KT patients from January 2010 to February 2016 at Seoul National University Hospital. The patients were divided into three groups as follows: HLA-incompatible (HLAi) group, ABO-incompatible (ABOi) group, and control group...

Primary plasma cell leukemia (pPCL) is a rare and aggressive plasma cell neoplasm, with rapidly progressing clinical course. We evaluated the treatment status and survival outcomes of 69 Korean patients with pPCL. Of them, 59 patients were treated; 15 (25.4%) were treated initially with novel agent-based regimens with upfront autologous stem cell transplantation (ASCT), 7 (11.9%) with conventional chemotherapy with upfront ASCT, 21 (35.6%) with novel agent-based regimens only, and 16 (27.1%) were treated with conventional chemotherapy alone...

OBJECTIVE: To evaluate the relationship between donor sex and hepatocellular carcinoma (HCC) recurrence after living donor liver transplantation. BACKGROUND: HCC shows a male predominance in incidence and recurrence after tumor resection due to sex differences in hepatic sex hormone receptors. There have been no studies evaluating the importance of donor sex on post-transplant HCC recurrence. METHODS: Of 384 recipients of livers, from living donors, for HCC: 104/120 who received grafts from female donors were matched with 246/264 who received grafts from male donors using propensity score matching, with an unfixed matching ratio based on factors like tumor biology...

Tooth develops through reciprocal interactions between oral epithelium and oral mesenchyme. To regenerate tooth, both components are necessary to mimic epithelial-mesenchymal interactions. In adult teeth, Hertwig's epithelial root sheath/Epithelial rests of Malassez (HERS/ERM) cells are unique epithelial cells which are derived from oral epithelium. In this study, we investigated whether HERS/ERM cells could have ameloblast-like characteristics via interaction with stem cells from human exfoliated deciduous teeth (SHEDs) as an oral mesenchymal component...

Oxidative stress activates macroautophagy/autophagy and contributes to atherogenesis via lipophagic flux, a form of lipid removal by autophagy. However, it is not known exactly how endogenous anti-oxidant enzymes are involved in lipophagic flux. Here, we demonstrate that the anti-oxidant PRDX1 (peroxiredoxin 1) has a crucial role in the maintenance of lipophagic flux in macrophages. PRDX1 is more highly expressed than other anti-oxidant enzymes in monocytes and macrophages. We determined that Prdx1 deficiency induced excessive oxidative stress and impaired maintenance of autophagic flux in macrophages...

BACKGROUND: Gain of function mutations in signal transducer and activator of transcription 1 (GOF-STAT1) cause a susceptibility to a range of infections, autoimmunity, immune dysregulation, and combined immunodeficiency. Disease manifestations can be mild or severe and life threatening. Hematopoietic stem cell transplantation (HSCT) has been utilized in some patients with more severe symptoms to treat and cure the disorder. The outcome of HSCT for this disorder is, however, not well established...

Inhibitor of DNA binding (Id) proteins play important roles in regulating cardiac development via paracrine signaling. Id1/Id3 knockout mice die at mid-gestation with multiple cardiac defects. Single Id knockout studies have not reported cardiomyopathies. To bypass embryonic lethality we used Tie2CRE-mediated recombination to conditionally delete Id1 against global Id3 ablation (Id cDKOs), which develops adult-onset dilated cardiomyopathy. We confirm upregulation of thrombospondin-1 (TSP1) in Id cDKO hearts...

BACKGROUND: Kidney re-transplantation is commonly considered to have a higher immunological risk than first kidney transplantation. Because of the organ shortage and increasing waiting lists, long-term outcomes of kidney re-transplantation are being studied. However, reports of re-transplantation outcomes are not common. We have reported our 30 years of experience with second kidney transplantations. METHODS: Of 1210 kidney transplantations between November 1982 and August 2016 performed in our hospital, 105 were second kidney transplantations (2nd KT)...

INTRODUCTION: The recurrence of IgA nephropathy (IgAN) after kidney transplantation (KT) has an effect on graft survival, but there are few reports about long-term clinical outcomes of KT with recurrent IgAN. This study shows the long-term clinical outcomes of KT in patients with IgAN. METHODS: All recipients who had biopsy-proven IgAN were followed from February 1990 to February 2016. We analyzed overall graft and patient survival rates, incidence of recurrent IgAN, factors affecting graft survival, and IgAN recurrence...

PURPOSE: Our objective was to investigate the effects of age on patient and graft survival in expanded criteria donor (ECD) renal transplantation. METHODS: Between February 2000 and December 2015, we analyzed 405 deceased donor renal transplants, including 128 grafts (31.9%) from ECDs. Based on recipient age and ECD criteria classification, the recipients were divided into four groups: Group I, non-ECD to recipient age <50 years; Group II, non-ECD to recipient age ≥50 years; Group III, ECD to recipient age <50 years; and Group IV, ECD to recipient age ≥50 years...

BACKGROUND: To overcome a shortage of donors, cadaveric pediatric en bloc kidneys can be used to expand the donor pool. Recent evidence shows that en bloc kidney transplantation (EBKT) has better outcomes than standard-criteria deceased adult donor kidney transplantation. We reviewed our experiences of EBKT and their outcomes. METHODS: From September 1996 to January 2016, 15 EBKTs were performed in Asan Medical Center. The characteristics of donors and recipients were analyzed...

Sirolimus (SRL), a mammalian target of rapamycin inhibitor, is widely used in transplantation, but the mechanisms whereby it induces adverse effects, such as proteinuria and edema, remain unclear. To determine whether isolated SRL induces proteinuria or not, the authors intraperitoneally injected C57BL/6 mice with different doses of SRL (0 mg/[kg·d], 3 mg/[kg·d], 10 mg/[kg·d], or 30 mg/[kg·d]) for 24 days. Urinary albumin excretion was then quantified using a double-sandwich enzyme-linked immunosorbent assay, and serum creatinine levels were measured using a single dry-film chemistry auto-analyzer...

BACKGROUND: Although the induction of mixed allogeneic chimera shows promising clinical tolerance results in organ transplantation, its clinical relevance as an anti-cancer therapy is yet unknown. We introduced a mixed allogenic chimera setting with the use of a murine colon cancer cell line, CT26, by performing double bone marrow transplantation. METHODS: We analyzed donor- and recipient-restricted anti-cancer T-cell responses, and phenotypes of subpopulations of T cells...

Herein, we report our experience of performing allogeneic orthotopic liver transplantation (LT) in nonhuman primates. We designed an allogeneic ABO-compatible orthotopic LT model in monkeys in a manner similar to that used in humans. We applied almost the same surgical procedures used for human conventional deceased donor LT. A total of 6 monkeys underwent allogeneic LT. One cynomolgus monkey aged 45 months (3.4 kg) and 5 rhesus macaque monkeys aged 50.2 ± 14.8 months (5.40 ± 0.33 kg) were used as recipients...

BACKGROUND: Liver transplantation (LT) is an effective treatment for patients with end-stage liver disease caused by auto-immune hepatitis (AIH). However, diagnosis of AIH can be challenging for patients with end-stage liver disease at the time of transplantation. We classified patients into "probable" or "definite" AIH groups, using the diagnostic criteria of the International Autoimmune Hepatitis Group, and compared the clinical outcomes of AIH after LT in these 2 groups. METHODS: We performed a retrospective study of 18 patients who were diagnosed with AIH and underwent LT from March 2003 to March 2015 at a single institute...

BACKGROUND: A higher body mass index (BMI) before kidney transplantation (KT) is associated with increased mortality and allograft loss in kidney transplant recipients (KTRs). However, the effect of changes in BMI after KT on these outcomes remains uncertain. The aim of this study was to investigate the effect of baseline BMI and changes in BMI on clinical outcomes in KTRs. METHODS: A total of 869 KTRs were enrolled from a multicenter observational cohort study from 2012 to 2015...

BACKGROUND: Precise monitoring of the glomerular filtration rate (GFR) is needed to estimate the allograft function in kidney transplant recipients (KTRs). The GFR is widely estimated with the use of formulas based on serum cystatin C (SCys) and serum creatinine (SCr) levels. We compared the efficacy of SCys-based equations with that of SCr-based equations to predict the allograft function. METHODS: We calculated the Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI Cr), CKD-EPI creatinine-cystatin C (CKD-EPI Cr/Cys), and CKD-EPI cystatin C (CKD-EP ICys) equations in 70 KTRs...

BACKGROUND: The recent progress and appropriate use of immunosuppressive drugs have considerably improved the short-term survival in kidney transplantation recipients (KTRs). The development of new strategies to improve long-term survival outcome after kidney transplantation is also becoming important. Although current diagnosis of allograft dysfunction relies on serum creatinine concentration and biopsy, they are nonspecific indicators of allograft function. Therefore, noninvasive, sensitive, and specific biomarkers for the prediction of long-term survival are needed...
