Opinions of Health Care Personnel Regarding Disincentives and Incentives for Living Kidney Donation at a Single Center.

BACKGROUND: Transplant societies continue to actively concentrate on increasing rates of living kidney donation (LKD) to bridge the gap between individuals awaiting transplantation and the number of kidneys available. A widely discussed strategy to increase living donation rates is the provision of incentives and removal of disincentives. Though opinions of the public regarding this strategy have been studied, the opinions of health care providers, including younger professionals, are less clear. We studied the opinions of medical students and other health care providers on strategies to increase LKD to determine if opinions were different among those < 25 or ≥ 25 years of age. METHODS: A simple cross-sectional survey was conducted at an academic medical center. Participants included medical students and employees in Internal Medicine, General Surgery, and the Organ Transplantation Center. Pearson's χ2 and Fisher's exact test were conducted on the responses regarding disincentives and incentives to determine whether opinions differed based on age. RESULTS: Six hundred and twenty-four participants completed the survey. There was no statistical difference in opinions between groups on reimbursing transportation costs, loss of wages, or childcare costs, but those aged ≥ 25 were more agreeable with covering food/lodging costs compared to those < 25 (96.5% vs 90.7%, P = .009). Respondents < 25 years old were more willing to donate a kidney for a financial incentive (P = .0002) accepting a median amount of $25,000. CONCLUSIONS: Health care personnel broadly support removing financial disincentives for living kidney donation, and those ≥ 25 were more in favor of covering food/lodging costs compared to those < 25. Those < 25 years old were more likely to accept financial incentives towards donating their kidney compared to those ≥ 25 years.

An Unexpected Surge in Plasma BKPyV Viral Load Heralds the Development of BKPyV-Associated Metastatic Bladder Cancer in a Lung Transplant Recipient With BKPyV Nephropathy.

We report a lung transplant recipient who developed BK polyoma virus (BKPyV) DNAemia and BKPyV nephropathy. With careful management of his immunosuppression he achieved significant reduction in BKPyV DNAemia and stabilization of his kidney function. He later developed a high-grade bladder cancer and shortly thereafter he experienced a major upsurge in the level of BKPyV DNAemia that coincided with the discovery of hepatic metastasis. Retrospectively, the bladder cancer and the hepatic secondary tumor stained uniformly for SV40 large T antigen, and the BKPyV DNA sequences identified in plasma corresponded to BKPyV DNA within hepatic tissue, indicating that the spike in BKPyV load was likely derived from the circulating tumor cells or cell-free tumor DNA following metastases of a BKV-associated cancer. To the best of our knowledge, this is the first description of a surge in BKPyV load in a patient with controlled BKPyVN that heralded the appearance of a metastatic urothelial malignancy. This report discusses the literature on BKPyV-associated malignancies and the possibility that unexplained increases in BKPyV DNAemia may be a biomarker for metastatic BKPyV-related urothelial cancer.

Light Chain Deposition Disease After Kidney Transplantation With Long Graft Survival: Case Report.

Light Chain Deposition Disease (LCDD) is a monoclonal immunoglobulin deposition disease that commonly affects kidneys among other organs. It leads to end-stage renal disease and has a high disease recurrence rate after kidney transplantation. This has led some authors to advise against transplantation in view of the poor long-term graft and patient outcomes. Recent literature has shown improvement/stabilization of native kidney disease following the use of bortezomib. We present 2 cases of LCDD after transplantation with graft dysfunction. They were both treated with different therapeutic agents to induce remission. Because sustained remission was not achieved they received bortezomib following which they have experienced a prolonged period of stable renal function with no clinically detectable disease. These unique cases highlight the possibility to achieve long-term stable graft function and disease remission after renal transplantation for LCDD.

Plasmacytoma-like post-transplantation lymphoproliferative disorder confined to the renal allograft: a case report.

A 44-year-old woman who had end-stage kidney disease from diabetes and hypertension underwent a deceased donor kidney transplantation. Eighteen months after the transplantation she developed an abrupt increase in her creatinine level and a kidney biopsy specimen showed the presence of a plasma cell-rich infiltrate. A vast majority of the plasma cells were kappa (κ) light chain restricted on in situ hybridization. κ and lambda (λ) free light chain were elevated in her serum and so was the κ/λ ratio. A bone marrow biopsy specimen showed no evidence of clonal plasmacytosis. A positron emission tomography (PET) scan showed hypermetabolic activity confined to the kidney. Prior to transplantation she was Epstein-Barr virus (EBV) immunoglobulin (Ig)G-negative but had detectable EBV based on polymerase chain reaction (PCR) in her blood during this episode. Despite reduction in immunosuppression there was no change in the κ/λ ratio and her renal function worsened. She underwent a transplant nephrectomy and her κ/λ ratio became normal. Twenty-one months later she is lymphoma-free and doing well on dialysis. Plasmacytoma-like post-transplantation lymphoproliferative disorder (PTLD) is rare and even more is the localization of the malignancy to the allograft. When reduction of immunosuppression is unsuccessful in treatment, removal of the organ may be necessary as is demonstrated in our case.

Vitamin D deficiency in community older adults with falls of gait imbalance: an under-recognized problem in the inner city.

INTRODUCTION: Recent reports suggest that vitamin D deficiency is both under-recognized and undertreated in the geriatric population. In particular, older adults with unexplained pain, falls, and gait disorders often may have osteomalacia from vitamin D deficiency. Currently, older adults are not screened for vitamin D status even when clinical skin suggest deficiency. Our pilot study determined the vitamin D status in older, inner city community adults with features suggestive of vitamin D deficiency. METHODS: The study was prospective and observational. Community-dwelling adults (> 60 years) from our ambulatory clinic or in-patient geriatric program, with features compatible with vitamin D deficiency (history of falls, gait imbalance, unexplained musculoskeletal pain, and/or fractures), were enrolled. IRB approval and signed informed consents were obtained. Following a history and physical exam, blood samples for vitamin D assay and routine chemistries were obtained. Additional information was collected on age, gender, race, dairy product intake, calcium and/or vitamin D supplement use, weekly sunlight exposure, season of exam (May-October vs. November-April), prior falls and fractures, musculoskeletal pain, and gait disturbances. RESULTS: Data were obtained from 48 patients (32F and 16M), mean age of 79 +/- 9 (SD) years (range 60-95). Seventy-seven percent of enrollees had gait disturbances, 77% had a history of falls, 29% had previous fractures and 6% had unexplained pain; 79% consumed milk daily, 25% took calcium supplements and 21% used vitamin D supplements (in a multivitamin or calcium supplement). Self-reported weekly exposure to sunlight ranged from 0 to 42 hours (clothing amount was highly variable). Fifty-four percent of this sample had sub-normal vitamin D status (serum vitamin D < 20 ng/mL). Patient age (P = 0.2287), gender (P=0.9270), exposure to sunlight (P=0.3493), season (P=0.573), and dairy intake (P = 0.735) were not associated with vitamin D status. However, 80% of vitamin D supplement users versus 37% of non-users had normal vitamin D status (P = 0.029) and 75% of calcium supplement users versus 36% of non-users had normal vitamin D status (P = 0.042). A logistic regression model determined that the use of vitamin D or calcium supplements decreased the risk of low vitamin D status by 94% and 93% (P = 0.009 and P = 0.010, respectively). CONCLUSION: In this pilot study of older adults with gait imbalance and falls, vitamin D deficiency (< 20 ng/mL) was observed in 54% of patients tested and previously unrecognized. Higher serum vitamin D levels appeared related to the use of vitamin D (in multivitamin or calcium supplements) suggesting that deficiency may be preventable and easily treated. As vitamin D deficiency is associated with substantial disability, the need for increased awareness to screen and prevent this disorder is evident.
