Removal of Large Middle Molecular Uremic Toxins: Room for Innovation
October 23, 2020 | 01:00 PM - 02:00 PM
Location: Simulive
Session Description
Hemodialysis remains the most common form of kidney replacement therapy worldwide for patients with ESKD. Despite advancements in dialysis technologies, morbidity, and mortality remain high for hemodialysis patients.
Urea clearance is the gold standard for measuring adequate dialysis clearance. The current technology for hemodialysis therapy (high-flux membranes) can clear uremic toxins up to 12,000 Daltons (12 kDa) but has very poor capacity to remove large middle molecular uremic toxins (25-60 kDa). These large middle molecules have been associated with chronic inflammation, atherosclerosis and calcification, structural heart disease, and secondary immunodeficiency.
This symposium discusses a potential role for the removal of these large middle molecules, including consideration of the available technology.
Support is provided by an educational grant from Baxter Healthcare Corporation.
Learning Objective(s)
- Describe the clinical relevance of large middle molecular uremic toxins in ESKD

Sahir Kalim, MD, FASN
Sahir Kalim is a physician scientist at the Massachusetts General Hospital (MGH) in Boston, Massachusetts, USA. He is an Assistant Professor of Medicine at Harvard Medical School, and co-director of the MGH Kidney Research Center. His clinical interests include managing late stage chronic kidney disease (CKD) as well as caring for patients with end stage kidney disease (ESKD) on dialysis. In addition to seeing patients, his research focuses on understanding the fundamental causes of the excess morbidity and mortality seen in patients with CKD in an effort to develop new targeted therapies. He has been awarded multiple NIH grants focused on proteomics, metabolomics, and clinical trials in CKD/ ESKD. Recently, Dr. Kalim’s work has linked a protein modification known as carbamylation to several adverse outcomes such as resistance to erythropoietin and mortality in patients with kidney disease. Similarly, using high throughput screening, his group has identified a number of novel metabolite derangements associated with cardiovascular disease in dialysis patients. He is now studying ways to correct these metabolic disturbances and determine, through clinical trials, if doing so results in improved patient outcomes.
