Low Bone Turnover in Chronic Kidney Disease Is Associated with Decreased VEGF-A Expression and Osteoblast Differentiation

Background: Low turnover bone (low bone formation rates (BFRs)) with decreased osteoblast number is common in patients with chronic kidney disease (CKD) and attributed to ‘over-suppression' of the parathyroid hormone (PTH) despite supra-physiologic levels. An alternative hypothesis is abnormal osteoblast differentiation, resulting in low BFRs due to reduced VEGF-A. Methods: We analyzed the expression of VEGF-A and mesenchymal stem cell (MSC) differentiation factors in freshly isolated bone marrow (BM) cells, and in BM cell-derived MSC in rats with different levels of BFRs and PTH (modulated by calcium and zoledronic acid). The regulators of VEGF in MSC were also determined. Results: VEGF-A expression was reduced in the BM cells from CKD vs. normal animals (p

Authors: Uchida N, Kumagai N, Kondo Y Abstract The kidney plays an essential role in the maintenance of homeostasis in healthy individuals, e.g., by regulating the amount of water and concentration of electrolyte in the body. Owing to the structural complexity, renal dysfunction is caused by a myriad of diseases and conditions, and in severe cases, it progresses to end-stage renal disease in which patients require renal replacement therapy, i.e., maintenance dialysis or kidney transplantation. The currently available therapeutic modalities, with the exception of renal transplantation, cannot recover severely deteri...

CONCLUSIONSDespite no measurable disease remaining on preinfusion imaging, CAR-T cell expansion was observed in 7 of 8 pts in this setting, similar to the expansion in adults with active r/r DLBCL. Five of the 8 pts remained on study and were progression free> 12 months after infusion, which is higher than would be estimated with bridging chemotherapy alone. These data provide preliminary evidence that CAR-T cells provide clinical benefit in pts with r/r DLBCL who achieve CR with subsequent therapies and for design of CAR-T cell trials as consolidative therapy.DisclosuresBishop: United Healthcare: Employment; Seattle Ge...

IntroductionBased on improvement of overall survival (OS), lenalidomide (R) maintenance after up-front autologous stem cell transplantation has recently been approved for multiple myeloma (MM) patients (pts). Conversely, in transplant non-eligible (TNE) pts R maintenance after R-based induction improved progression free survival (PFS) but had no impact on OS. First-line treatment with VMP is considered a standard of care for newly diagnosed (ND) TNE pts, but whether maintenance therapy with R after VMP induction can further improve PFS and OS is currently unknown.AimsThe prospective phase IIb GERMAIN trial (EudraCT-No: 201...

Conclusion:Long-term outcome of SAA patients treated with ATG/CSA was not influenced by supplementing G-CSF in term of OS, EFS, death rates, relapse, PNH, secondary MDS/AML, solid cancer and non-malignant late complications. Due to the pre-cancer nature of the disease and its long-lasting treatment, patients treated with IST are at risk for a number of malignant and non-malignant late complications. It is somewhat disappointing that in this careful followed cohort less than 25% of patients are alive and event-free 10-15 years after initial treatment.DisclosuresPeffault De Latour: Pfizer Inc.: Consultancy, Honoraria, Resear...

The objective of this study is to evaluate the progression of renal function in allogeneic hematopoietic stem cell transplant (HSCT) patients, before, during and after cyclosporine therapy.Methods:This is a retrospective single arm cohort study evaluating the impact of cyclosporine on renal function in patients who underwent allogeneic HSCT from 2003 through 2013. Patients age≥ 14 years who underwent allogeneic HSCT and received cyclosporine as graft-versus-host disease (GVHD) prophylaxis and alive two years post HSCT without disease relapse or GVHD were included in the study. Primary outcome was the change in serum cre...

This study aims to determine risk factors for the development of CA in patients undergoing HSCT.Methodology: A retrospective analysis of 138 consecutive patients undergoing HSCT at our institution between January 1st, 2015 and December 31st, 2017 was performed. One patient was excluded due to lack of baseline EKG. Data from patients ≥ 18 y/o who underwent autologous or allogeneic HSCT was analyzed. Variables analyzed included: age, gender, ethnicity, prior HSCT, diagnosis, type of transplant (autologous vs allogeneic), prior anthracycline exposure, diabetes mellitus, chronic kidney disease, hypertension, coronary artery...

Conclusion: This study found that sociodemographic factors were associated with the risk of developing medical conditions in AYA NHL, ALL and AML survivors. As expected, the risk of medical conditions varied by cancer type and treatment, with those undergoing SCT having a higher risk of medical conditions regardless of cancer type. NHL and ALL survivors who were uninsured or publicly insured were at a consistently higher risk of developing medical conditions, as were Hispanic ALL survivors and Black AML survivors. Our findings highlight the higher burden of medical conditions in subgroups of cancer survivors that may relat...

ABSTRACT Understanding epigenetic mechanisms is crucial to our comprehension of gene regulation in development and disease. In the past decades, different studies have shown the role of epigenetic modifications and modifiers in renal disease, especially during its progression towards chronic and end-stage renal disease. Thus, the identification of genetic variation associated with chronic kidney disease has resulted in better clinical management of patients. Despite the importance of these findings, the translation of genotype–phenotype data into gene-based medicine in chronic kidney disease populations still lacks f...

AbstractAlthough mesenchymal stem cell (MSC) ‐based therapy is a treatment strategy for ischemic diseases associated with chronic kidney disease (CKD), MSCs of CKD patients undergo accelerated senescence, with decreased viability and proliferation upon uremic toxin exposure, inhibiting their utility as a potent stem cell source for transplan tation therapy. We investigated the effects of melatonin administration in protecting against cell senescence and decreased viability induced by pathophysiological conditions near the engraftment site. MSCs harvested from CKD mouse models were treated with H2O2 to induce oxidative st...
