Atherosclerosis, Cardiovascular Disease, Dialysis, Inflammation
Conditions
Brief summary
Patients with kidney failure on hemodialysis have an extremely high rate of cardiovascular disease including atherosclerotic cardiovascular disease. This, at least in part, is due to the chronic inflammatory status usually seen in these patients. Here we try to see if treatment with extended release nicotinic acid (Niaspan) can reduce their overall inflammatory burden (in general) and the atherosclerotic plaque inflammation (in particular).
Interventions
Subjects will start on 500 mg per day of Niaspan for 4 weeks, then the dose will be increased to 1000 mg per day of Niaspan for 4 weeks, then the dose will be increased to 1500 mg of Niaspan per day for 4 weeks, after this subjects with weight of less than 60 kg will continue at 1500 mg per day of Niaspan for another 12 weeks whereas in subjects with weight of more than 60 kg the dose will be increased to 2000 mg of Niaspan per day which will be continued for 12 weeks.
