Brief Summary:


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.

Condition or disease
Vitamin D Deficiency End Stage Renal Disease

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.
