Brief Summary

The objective of this study is to assess the prevalence of vitamin D deficiency in patients with chronic Hepatitis C compared to a matched control group of healthy individuals in the Sioux Falls area. It is the hypothesis of this study that vitamin D deficiency is more common in patients with chronic Hepatitis C compared to the healthy control group.

Outcome Measures

Primary Outcomes (1)

  • The Vitamin D levels of the 100 subjects will be statistically analyzed as the primary variable and correlated with the rest of the variables via ANOVA and meta-analysis

    This research study consists of a single clinic visit. After study subjects have completed the informed consent process and are determined to meet study eligibility, a blood sample will be collected. Values from these lab samples will be compared between study arms.

  • Men and women between the ages of 25 and 55
  • Diagnosis of chronic hepatitis C

You may not qualify if:

  • Taking a vitamin D supplement (by itself or as part of a multivitamin), a calcium supplement and/or biphosphonates
  • Has acute hepatitis C infection
  • Has chronic hepatitis B infection
  • Had gastric bypass surgery
  • Has chronic kidney disease
  • Men and women between the ages of 20 and 60
  • Has a body mass index (BMI) between 20 and 35
  • Taking a vitamin D supplement (by itself or as part of a multivitamin), a calcium supplement and/or biphosphonates
