Efficacy Of Ergocalciferol In Adults According To BMI
May 10, 2017 updated by: Walter Reed National Military Medical Center
Vitamin D insufficiency is an increasing trend in the United States.
According to the NHANES data collection there was a near doubling of patients with vitamin D deficiency in 10 years.
Vitamin D deficiency is associated with several adverse outcomes such as increased fractures, certain microbial diseases, cardiovascular diseases, and metabolic dysfunction.
The increasing prevalence of vitamin D deficiency has been attributed to the increasing prevalence of obesity.
Several studies have shown that obese patients have lower 25-OH vitamin D (25-OHD) levels compared to nonobese patients and obese patients require more vitamin D compared to nonobese patients.
The most commonly prescribed medication to replete vitamin D deficiency is oral ergocalciferol.
To date, no prospective trials have been published to evaluate a standard protocol in the treatment of vitamin D insufficiency in adults.

Description
Inclusion Criteria:
- Study subjects have to be between the ages of 18 to 65 with a serum 25OHD level less than 20 ng/ml.
Exclusion Criteria:
Participants will be excluded if they have any of the following:
- Due to the inaccuracies of BMI in patients with increased muscle mass, in group with a BMI 25-35: men with a waist circumference < 90 cm ; women < 80 cm
- Chronic liver disease defined by any clinical or a history of serum AST or ALT > 2 times ULN
- Kidney disease defined as a GFR <60 ml/min
- Sarcoidosis
- Any known malignancy
- Known malabsorption disorder to include inflammatory bowel disease, celiac disease, cystic fibrosis, history of gastric bypass
- Primary hyperparathyroidism or hypercalcemia,
- Patients that are pregnant or considering pregnancy.
- Patients taking certain medications such as glucocorticoids, anti-seizure medications such has phenobarbital or phenytoin or patients taking antiviral medications for HIV as these are known to cause vitamin D deficiency
- Individuals excluded from having a DXA scan
Study participants will be excluded from having a DXA scan if any of the following:
- Any amputation of a extremity including toes
- If they have a pacemaker, automatic defibrillator, coronary stents or metal suture material in the heart
- If they have artificial joints, pins, plate or any other type of metal objects
- If they have received contrast material such as barium in the past 7 days
- If they have had a nuclear medicine study in the past 3 days
