A Study of 25-hydroxy Vitamin d Levels in Non-itching Hemodialysis Patients

A Cross-sectional Analysis of 25-hydroxy Vitamin d Levels in Non-itching Hemodialysis Patients

• Status: Completed
• Phase: —
• Study type: Observational
• Enrollment: 50 (actual)
• Sponsor: Winthrop University Hospital · Academic / Other
• Sex: All
• Age: 18 Years – 85 Years
• Healthy volunteers: Not accepted

Summary

Hypothesis: 25-hydroxy vitamin D levels in non-itching hemodialysis (HD) patients will be higher than those in HD patients with itching 25-hydroxy vitamin D levels will be measured in non-itching hemodialysis patients and compared to levels previously measured in a previous study of 25-hydroxy vitamin D levels of patients complaining of itching.

Detailed description

25-hydroxy vitamin D levels from non-itching HD patients in this study will be compared to 25-hydroxy vitamin D levels from our ongoing study in HD patients with itching. The primary endpoints for both studies are continuous variables. Student's t test will be used to test for statistical significance. Multiple regression analysis will be used for controlling covariates and testing the interaction among covariates.
