Randomized Study of Folic Acid Therapy for Hyperhomocysteinemia in Patients With End Stage Renal Disease Receiving Hemodialysis
OBJECTIVES: I. Compare the efficacy of two doses of folic acid in normalizing plasma total homocysteine concentration in patients with end stage renal disease receiving regular hemodialysis therapy resulting in hyperhomocysteinemia.
II. Determine the requirement of co-supplementation with extra pyridoxine (vitamin B6) and cyanocobalamin (vitamin B12) daily in these patients.
III. Assess the safety and tolerability of this therapy in these patients.
|End Stage Renal Disease Hyperhomocysteinemia||Drug: cyanocobalamin Drug: folic acid Drug: pyridoxine|
|Study Design:||Primary Purpose: Treatment|
|Study Start Date:||June 1999|
|Estimated Study Completion Date:||September 2000|
PROTOCOL OUTLINE: This is a randomized, placebo controlled study. Patients are stratified according to prestudy homocysteine levels (above or below average). Patients are randomized to receive placebo or one of two doses of oral folic acid, with or without pyridoxine and cyanocobalamin.
Arm I: Patients receive oral placebo daily. Arm II: Patients receive oral pyridoxine, cyanocobalamin, and oral placebo daily.
Arm III: Patients receive oral pyridoxine, cyanocobalamin, and folic acid daily.
Arm IV: Patients receive oral pyridoxine and cyanocobalamin plus a higher dose of folic acid daily.
Arm V: Patients receive oral placebo and oral folic acid daily. Arm VI: Patients receive oral placebo and higher dose folic acid daily. Treatment continues for 8 weeks.
