About
Patients with end-stage renal disease on dialysis (ESRD5D) are 4-5x more likely to suffer from a fracture. Fractures can occur spontaneously but typically occur after a fall. Further, 70-90% of patients with ESRD5D are vitamin D deficient. Vitamin D supplementation has become routine care for many in this patient population, but evidence is lacking to support this practice. The proposed projects objective is to gather needed preliminary data regarding the effects of vitamin D supplementation on balance and muscle strength in patients with ESRD5D.
Full description
In 2009, ~6% of the annual Medicare budget was spent to treat people with end-stage renal disease on dialysis (ESRD5D), making chronic kidney disease (CKD) an important and costly health problem affecting the United States. These patients are 4-5x more likely to suffer from a fracture. Fractures can occur spontaneously but typically occur after a fall. Further, 70-90% of patients with ESRD5D are vitamin D deficient. Vitamin D supplementation has become routine care for many in this patient population; without evidence to support this practice. While studies on the elderly document the effect of vitamin D in decreasing fall risk, findings are inconclusive for those elderly individuals with ESRD5D. The proposed projects objective is to gather needed preliminary data regarding the effects of vitamin D supplementation on balance and muscle strength in patients with ESRD5D. Thirty patients with ESRD5D will be recruited and randomized into two groups: 1) 4000 or 2) 800 IU oral, vitamin D taken daily. Men and women (ages 21-70 years) will be recruited from among patients receiving hemodialysis at a UNMC-directed dialysis facility. Other inclusion criteria include 1) likely to be able to complete the study; 2) ambulatory, without a walking aid; 3) able to complete questionnaires interactively with a research nurse; and 4) greater than 3 months on hemodialysis. Exclusion criteria include patients on peritoneal dialysis, allergy to vitamin D, liver disease, intestinal disorders that would interfere with vitamin D absorption; vitamin D supplements >800 IU per day, glucocorticoids, anticonvulsants, drug therapies for osteoporosis. All patients will be receiving standard of care per their nephrologist. Functional data will be collected at baseline, three, and six months. Data collected will include balance, muscle strength, and falls. Data to monitor vitamin D levels and calcium will be pulled from their medical record. There is no follow up after the six month long study.
