Comparative Study
Long-term outcome of kidney retransplantation in comparison with first kidney transplantation: a report from the Thai Transplantation Registry.
Kidney retransplantation is a high-risk procedure that is increasingly performed because of previous graft failure. The aim of this study was to determine the long-term outcomes of kidney retransplantations compared with first kidney transplantations under the current era of immunosuppression. ⋯ The 10-year patient and graft survival rates of kidney retransplantation were acceptable. The combination of induction therapy with a calcineurin inhibitor and a mycophenolate mofetil/mychophenolic acid-based regimen lead to outcomes comparable to first kidney transplantations among our cohort of 3337 patients.

When the Japanese Organ Transplantation Act was issued, the Japanese Organ Transplantation Network (JOT) was established in 1997. JOT lists recipients, assesses and manages organ donors, and educates publics and headquarters for organ donations. JOT procurement transplant coordinators (PTC) play roles in obtaining consent from relatives for organ donation, donor evaluation and management, organ recovery management, organ transport, and care of donor families during and after donation. Every prefecture has at least one PTC who is mainly working in public education and hospital development. They also help the JOT PTC at the time of organ procurement. Most prefectures commission hospital staff in the procurement hospital to be an in-hospital PTC (In-Hp PTC), who make their hospital staff aware of organ donation and support organ procurement. Although the Act was revised in 2010 with brain-dead organ donation increased from 13 to 44 cases yearly, the number was still extremely smaller than other developed countries. In these circumstances, In-Hp PTC may play greater roles to increase donation and smooth procurement procedures Our primary aim was to describe the current status of In-Hp PTC in Japan. ⋯ To establish an organ procurement system and increase organ donation, In-Hp PTC have important roles in Japan. However, none is a full-time In-Hp PTC. Most In-Hp PTC require more professional education. A systematic education program for each occupation must be established soon.

Delayed graft function (DGF) is a common complication after transplantation. Its incidence is increased among patients receiving a graft from an expanded-criteria donor. Urinary neutrophil gelatinase-associated lipocalin (uNGAL), an acute kidney injury marker, could in the first days after transplantation be an early marker of DGF. ⋯ We observed that mean uNGAL concentrations, Cystatin C, serum creatinine, and albumin/creatinine ratio were significantly lower in the non-DGF cohort on all measured days. uNGAL at day 3 showed a positive correlation with serum creatinine at day 10 (R = 0.58; P < .00) and day 30 (R = 0.57; P = .016) as well as with the length of hospital stay (r = 0.47; P < .00). Receiver operating characteristic analyses performed to assess the potential of uNGAL to predict DGF showed an area under the curve for day 3 of uNGAL of 0.917 (confidence interval [CI], 0.79-1.00; P = .00), with an optimal cutoff level of 124 ng/mL, sensitivity of 80% (CI, 62%-97%), and specificity of 83% (62%-104%; P = .001). In the first days after transplantation, uNGAL could be an early marker of DGF, providing additional information to standard biomarkers and potentially helping clinicians to take early measures to mitigate DGF.

Presumed consent legislation has been advocated by some as an effective measure to improve organ donation. In Chile, a new presumed consent legislation was passed, replacing an informed consent legislation. As of January 2010, Chilean citizens older than 18 years were considered to be organ donors unless they had previously declined donation. The aim of this study was to evaluate the impact of this legislation on donation rates at 2 years after its implementation. ⋯ In Chile, presumed consent legislation not only did not increase but seems to have had a deleterious effect on organ donation, reflecting an increase in family refusals and a high percentage of nondonors in the registry.

Antibody-mediated rejection (AMR) and inferior graft outcome remain the 2 most important obstacles to successful kidney transplantation in human leukocyte antigen (HLA)- and ABO-incompatible recipients. We report a single-center experience in the outcome of desensitized living donor HLA- and ABO-incompatible kidney transplantation. ⋯ Our risk stratification for desensitization strategy achieved a low incidence of AMR among HLA- and ABO-incompatible kidney transplant recipients. Their 2-year data appear to be comparable to HLA- and ABO-compatible transplantations.
