Severity of Pruritis [ Time Frame: Baseline and end of study (up to 12 weeks) ]

Randomized patients will fill out a survey with questions about the degree and location of their pruritis at baseline and end of study. The total score ranged from 0-21 with 21 being the most severe and zero being the absence of any of the measures of pruritis.

Last observation was carried forward to end of study. A decrease in the Severity of Pruritis score over time indicated an improvement in the severity of pruritis.

Change in severity of Pruritis [ Time Frame: 3 months ]
Randomized patients will fill out a survey with questions about the degree and location of their pruritis at baseline and then every 2 weeks until the end of study. Vitamin D and metabolite levels will be measured at baseline, mid study,and on completion of study.

A Study of Oral Ergocalciferol to Treat Pruritis in Hemodialysis Patients
A Randomized Prospective, Double-Blind Placebo Controlled Study of Oral Ergocalciferol in the Treatment of Pruritis in Hemodialysis Patients

Pruritis (itching) is common in many people with chronic renal failure on hemodialysis. There may be many different reasons for the pruritis. Efforts to treat the problem have not been very effective.

Vitamin D levels have been found to be low in many hemodialysis patients. Since vitamin D plays an important role in the skin and is effective in treatment of certain skin conditions that involve pruritis, it may have a role in treatment of pruritis in hemodialysis patients.

The objective of the investigators study is to determine the effect of supplementation with oral vitamin D2 (ergocalciferol) on pruritis in hemodialysis patients.

Vitamin D2 is a fat soluble steroid hormone precursor which must be hydroxylated in the liver and kidney respectively to make the active form 1-25-Vitamin D. This active metabolite and related analogs have been synthesized and are frequently used in the treatment of hyperparathyroidism in patients with chronic kidney disease. However the active metabolite may not be back metabolized to the precursor forms which may have functions in other organs including the skin. Supplementation of hemodialysis patients with oral vitamin D forms would provide a source of precursors for use throughout the body.
