Vitamin D Deficiency Likely Among Kidney Disease Patients Starting Dialysis
Vitamin D deficiency is common in patients with end-stage renal disease (ESRD) on dialysis, but it''s not clear which patients are at increased risk. Ishir Bhan, MD, MPH (Massachusetts General Hospital), and his colleagues sought to determine whether routinely measured clinical and demographic characteristics could identify dialysis patients who have a high risk of vitamin D deficiency.
The researchers analyzed data from 908 patients in the Accelerated Mortality on Renal Replacement (ArMORR) cohort, a nationally representative group of U.S. dialysis patients. Data from 60% of the patients were used to find potential predictors of vitamin D deficiency, while data from the other 40% of patients were used to validate the predictors.
The investigators found that 79% of the study population was vitamin D deficient. Black race, female sex, winter season, and low blood levels of the protein albumin (≤ 3.1 g/dL) were the strongest predictors of vitamin D deficiency. In the validation set, the presence of low blood albumin levels and winter season increased the likelihood of vitamin D deficiency in black females (from 90% to 100%), black males (from 85% to 100%), white females (from 82% to 94%), and white males (from 66% to 92%).
