Session: Global Challenges of CKD

Sub-session: CKD in the United States and Europe: Juxtaposing the Epidemiology and Evolution

Presenter: Kitty J. Jager, MD, PhD, Academic Medical Center

There are marked differences in chronic kidney disease (CKD) prevalence and incidence trends between the Unites States and Europe. Even within countries there are enormous disparities.

During a deep dive into the granularity of available data, Kitty J. Jager, MD, PhD, Academic Medical Center, pointed out how, where, and sometimes why such differences in prevalence and incidence of CKD exist. Identifying and interpreting this data, Dr. Jager suggested, is critical to reducing the burden of CKD.

Session: High-Impact Clinical Trials

Sub-session: Effects of Vitamin D and Omega-3 Fatty Acid Supplementation on Kidney Function and Damage in Type 2 Diabetes

Presenter: Ian H. de Boer, MD, MS, Division of Nephrology and Kidney Research Institute, University of Washington

Ian H. de BoerIt’s official. Two supplement darlings — Vitamin D and omega-3 fatty acid (often sold as fish oil) — do not help people with type 2 diabetes stave off chronic kidney disease. That’s according to a five-year study of kidney function, which included 1,312 adults with type 2 diabetes.

Poster: SIERRAS: A Phase 3, Open-Label, Randomized, Active-Controlled Study of the Efficacy and Safety of Roxadustat in the Maintenance Treatment of Anemia in Subjects with ESRD on Stable Dialysis

Authors: Chaim Charytan, MD, Nephrology Associates, PC, New Rochelle, New York, et al

Roxadustat (ROXA) is an oral hypoxia–inducible factor prolyl hydroxylase inhibitor that stimulates erythropoiesis and regulates iron metabolism. And the drug — a novel first-in-class treatment for certain people with anemia from chronic kidney disease (CKD) — is being closely watched as its Phase III program pooled analyses continue to prompt headline-worthy news. In short, ROXA shows positive efficacy and no increased cardiovascular risk in patients with anemia from chronic kidney disease.

Session: Hot Off the Press: The Advancing American Kidney Health Initiative and More

Sub-Session: Deep Dive on New Kidney Care Delivery Models

Presenter: Tom Duvall, Acting Division Director for the Division of Special Populations and Projects at the Center for Medicare and Medicaid Innovation

Even on the final day of Kidney Week 2019, the remaining attendees’ energy level and riveted interest remained high — particularly in the morning session devoted to late-breaking developments in public policy.  Case in point, the sub-session on new kidney care delivery models, present by Tom Duvall, Acting Division Director for the Division of Special Populations and Projects at the Center for Medicare and Medicaid Innovation (CMMI), which contains the CEC Model, the KCC Model, and the ETC Model.

Session: High-Impact Clinical Trials

Presenter: Robert Provenzano, MD, FACP, FASN, Chief Medical Officer, Nephrology Practice Solutions & Vice President, Medical Affairs

Before a packed crowd, Robert Provenzano, MD, FASM, DaVita Healthcare, presented pooled efficacy and cardiovascular (CV) safety analyses from the pivotal Phase III program assessing roxadustat for the treatment of patients with anemia from chronic kidney disease (CKD).

Finnian R. McCausland

Looking out to a booked-solid room, Finnian R. McCausland, MBBCh, relayed the results of a trial concerning the effects of angiotensin-neprilysin inhibition on renal outcomes in patients with preserved ejection fraction.

Session: Linking lifestyle, BP, and kidney diseases: What is the evidence?

Presenter: Hoon-Ki Sung, MD, PhD

Dr. Hoon Ki SungIntermittent fasting (IF) is currently a popular new “diet trend,” especially among well-known Hollywood stars, like Jennifer Anniston. But what does the research have to say about it, specifically, its effect on reducing obesity? And, what other health benefits might it offer?

Session: Diet and Acid in CKD: Where Do We Stand?

Subsession: Plant-Based Diets: Pros and Cons in CKD

Presenter: Juan Jesus Carrero, MD, PharmD, PhD, Karolinska Institutet

It’s a hot topic. It’s more than hot. And if the SRO turnout to hear Dr. Carrero discuss plant-based diets in terms of CKD is any indication, the subject is red hot.

The session began with a brief review of current dietary recommendations for those with chronic kidney disease (CKD), which traditionally focuses on quantity — from adjusting protein intake to restricting single micronutrients (sodium, phosphorus, potassium, and calcium) to ensuring sufficient energy.

Leyuan XuAbnormal accumulation of macrophages, dendritic cells, and T cells may lead to progressive interstitial fibrosis, sustained inflammation, and kidney injury in the setting of maladaptive kidney repair following IRI. Blocking homing chemokines may serve as a therapeutic target to attenuate CKD progression.

Poster: Racial/Ethnic Disparities in Atrial Fibrillation Treatment and Outcomes in US Dialysis Patients

Presenter: Adan Z. Becerra PhD, Social & Scientific Systems

Authors: Paul L. Kimmel, MD, FASN, National Institute of Diabetes and Digestive Kidney Diseases (NIDDK), Salina Paulette Waddy, MD, Atlanta Veterans Administration, Allen J. Solomon, MD, The George Washington University, Adan Z. Becerra PhD, Social & Scientific Systems, Julia B.

Abbott, MD, MPH, The National Institutes of Health, NIDDK,

Increased racial/ethnic disparities in stroke rates among end-stage renal disease (ESRD) dialysis patients with atrial fibrillation (AF) are partially explained by lower use of oral anticoagulants among Blacks, Hispanics, and Asians. The reasons for these racial disparities in practice are unknown, although the results support an identified need to develop strategies that will maximize stroke prevention in minority populations and resolve system barriers between patient/physician that may block optimal treatment.

Session: Linking Lifestyle, BP, and Kidney Diseases: What Is the Evidence

Presenter: Danielle L. Kirkman, PhD

Dr. Danielle KirkmanIn this standing room only session, Danielle L. Kirkman, PhD, from the Virginia Commonwealth University, led the discussion surrounding the links between lifestyle, blood pressure, and kidney diseases with her presentation entitled, “The Physiology Behind the Effect of Exercise on Hypertension and Kidney.”

Advancement, progress, breakthrough, headway – these nouns pop up routinely on the ASN Kidney Week 2019 mobile app. Here’s one continuing story that comes with particularly grand plans – and so far everything is on a steady course toward success.
