Chronic kidney disease (CKD) patients who receive medical nutrition therapy (MNT) from a registered dietitian (RD) with renal expertise may improve their nutritional status and delay dialysis initiation.
A study, where the investigators examined the medical records of 265 CKD patients treated at a single outpatient clinic in Vermont from 2003-2013. Of these, 147 received MNT from an RD. Patients receiving MNT had a smaller decline in estimated glomerular filtration rate: 0.3 vs. 9.9 mL/min/1.73 m2 for non-MNT patients. After adjusting for CKD stage, that difference grew between groups. In addition, the non-MNT group was 3 times more likely to start dialysis; that rose to nearly 3.5 times for stage 3 and 4 CKD patients not receiving MNT.
Albumin and markers of CKD mineral and bone disorders (phosphorus, calcium, and intact parathyroid hormone) were more likely to be in the normal range for patients receiving MNT.
