Joachim H. Ix, M.D., M.A.S., is Professor and Chief of the Division of Nephrology-Hypertension at the University of California, San Diego. He is a nephrologist, epidemiologist, and clinical trialist. His research focuses in two main areas, novel therapies in chronic kidney disease mineral bone disorders (CKD-MBD) and noninvasive assessment of kidney tubule health. Chronic kidney disease (CKD) leads to altered homeostasis of calcium, phosphate, and associated regulatory hormones that are strongly associated with vascular calcification and cardiac structural abnormalities. His team has used large observational epidemiological studies to quantify the strength of associations of these factors with cardiovascular disease and related outcomes in CKD patients. The strength and consistency of these findings makes interventions to improve CKD-MBD an important target in lowering cardiovascular disease event risk in CKD patients. He is now evaluating the safety and efficacy of novel therapies that lower intestinal phosphate absorption in CKD patients in multicenter randomized clinical trials. Second, his team is interested in identifying novel noninvasive markers of kidney tubule cell health. Pathological studies demonstrate that kidney tubule atrophy and fibrosis are important determinants of kidney disease progression, but they are poorly captured by glomerular markers of kidney health. Dr. Ix and his team have evaluated a number of blood and urine proteins that noninvasively assess the health of kidney tubule cells, and are working to determine if these markers improve assessment of risk of future kidney disease progression and cardiovascular disease risk. Dr. Ix served on the Institute of Medicine Committee on Consequences of Sodium Reduction in Populations. Dr. Ix received his B.S. from the University of California, San Diego; his M.D. from the University of Chicago Pritzker School of Medicine; and his M.A.S. from the University of California, San Francisco.

As essential nutrients, sodium and potassium contribute to the fundamentals of physiology and pathology of human health and disease. In clinical settings, these are two important blood electrolytes, are frequently measured and influence care decisions. Yet, blood electrolyte concentrations are usually not influenced by dietary intake, as kidney and hormone systems carefully regulate blood values.

Over the years, increasing evidence suggests that sodium and potassium intake patterns of children and adults influence long-term population health mostly through complex relationships among dietary intake, blood pressure and cardiovascular health. The public health importance of understanding these relationships, based upon the best available evidence and establishing recommendations to support the development of population clinical practice guidelines and medical care of patients is clear.

This report reviews evidence on the relationship between sodium and potassium intakes and indicators of adequacy, toxicity, and chronic disease. It updates the Dietary Reference Intakes (DRIs) using an expanded DRI model that includes consideration of chronic disease endpoints, and outlines research gaps to address the uncertainties identified in the process of deriving the reference values and evaluating public health implications.
