Roy Bloom, MD is the Medical Director of the Penn Transplant Institute Kidney and Pancreas Transplant Program. He has served on KDIGO Work Groups related to the development of clinical practice guidelines for both managing hepatitis C virus in kidney disease, as well as for the management of kidney transplant recipients and has participated as a member of KDOQI Commentary Work Groups for the KDIGO Clinical Practice Guidelines related to both Care of the Kidney Transplant Recipient as well as for Lipid Management in Chronic Kidney Disease. His current research interest is focused in three major arenas. The first area of investigation involves clinical trials with contemporary and emerging therapies. Besides conducting studies with emerging immunosuppressive agents, his current clinical trial portfolio includes the assessment of both innovative strategies and regimens to reduce-transplant related complications such as ischemia-reperfusion injury, delayed graft function, new onset diabetes, as well as the use of novel non-invasive biomarkers as early diagnostic indicators of subsequent immune-mediated allograft injury. A second field of interest relates to pharmacokinetic evaluation of therapies in kidney recipients, specifically evaluating special subpopulations for whom available data on which to base dosing is relatively limited. A final investigational theme analyzes pre- and post-transplant outcomes related to viral infections, in particular hepatitis C virus, hepatitis E virus, CMV, HIV and BK virus.

Lawrence Holzman, MD is a C. Mahlon Kline Professor of Medicine and Chief of the Renal-Electrolyte and Hypertension Division at the University of Pennsylvania. His clinical research work focuses on glomerular diseases of the kidney. These are a large group of rare diseases that in aggregate account for a large fraction of patients whose kidney disease ultimately results in kidney loss, requiring dialysis or transplantation. Dr. Holzman co-founded NEPTUNE, an international consortium of academic medical centers for the clinical investigation of patients presenting with nephrotic syndrome, including patients with steroid-resistant nephrotic syndrome, focal and segmental glomerulosclerosis and membranous nephropathy. This organization conducts an NIH-sponsored multi-year longitudinal observational study that is following a large number of patients with glomerular disease, collecting clinical data and biological samples that should allow a comprehensive understanding of these diseases. By applying a variety of scientific approaches including genetics, systems biology, biomarker discover and validation, and epidemiology NEPTUNE expects to make rapid progress during the coming few years. By participating as a principal investigator in a newly created NIH-supported consortium called CureGN, Dr. Holzman is helping lead a second complementary national consortium studying glomerular disease.

Dr. Negoianu is a member of the steering committee of the AVOID-HF trial. This a national multicenter trial that plans to enroll 800 patients hospitalized for heart failure and fluid overload. The trial will compare fluid removal with an ultrafiltration machine (also sometimes called an aquapheresis machine) versus fluid removal via loop diuretics (the class of medications typically used to treat fluid overload). The primary outcome of the study consists of the rate of both hospital re-admissions and unscheduled treatments for fluid overload in the first 90 days after discharge.

His research focuses on: a) developing effective strategies to increase access to kidney transplantation; b) improving the process of selecting and caring for living kidney donors; c) determining outcomes of health policies on vulnerable populations with renal disease, including the elderly; d) testing strategies to improve important health behaviors such as medication adherence; and e) transplant ethics. He is the recipient of a Presidential Early Career Award for Scientists and Engineers at the White House. He is a past chair of the Ethics Committee for the United Network for Organ Sharing (UNOS), which oversees organ allocation and transplant regulation in the U.S. and is an Associate Editor for the American Journal of Kidney Diseases. He co-leads multiple pilot trials of transplantation using hepatitis C-infected organs from deceased donors into uninfected recipients, for which his group received the Innovation Award from the American Society of Transplantation.
Dr. Reese has written specifically about the ethical implications of accepting live kidney donors with risk factors for kidney disease, outcomes for living donors and individuals declined for donation, the effects of organ allocation policy on vulnerable subgroups including children and the elderly, and better strategies to promote the careful use of higher-risk organs.
