Nutrition Therapy May Improve Kidney Failure Risk in Patients With CKD

Medical nutrition therapy may help reduce the risk of hyperphosphatemia among patients with chronic kidney disease (CKD) who are on hemodialysis, according to results from a study presented at the Food & Nutrition Conference & Expo 2020.

Patients with CKD who are on hemodialysis have a higher risk of hyperphosphatemia and other CKD-related conditions such as CKD mineral and bone disorder.

To better understand how nutritional interventions may affect serum phosphorus concentrations, the researchers conducted a literature review of 13 controlled trials identified via 4 online databases.

The trials ranged in sample sizes (31-570 participants), study duration (2-12 months), designs, populations, strategies, and outcomes.

Overall, though, the researchers were able to determine that medical nutrition therapy had improved serum phosphorus concentrations in 11 of the 13 studies, compared with the reference groups.

“While intensified or targeted [medical nutrition therapy] is generally efficacious for lowering serum phosphorus concentrations in [hemodialysis] patients, how and if [medical nutrition therapy] protocols should be standardized and implemented in clinical practice remains unclear,” the researchers concluded.
