Effective homocysteine-lowering vitamin B treatment in peritoneal dialysis patients.

Background: Hyperhomocysteinemia, a risk factor for atherosclerosis, is frequently detected in patients with renal failure. Vitamin B supplementation reduces but rarely normalizes homocysteine (Hcy) levels in hemodialysis patients. There are no data about the effects of vitamin B therapy on Hcy levels in patients on peritoneal dialysis (PD).

Effects of folic acid treatment on homocysteine levels and vascular disease in hemodialysis patients.

Background: Cardiovascular disease is the most important cause of morbidity and mortality in hemodialysis patients. These patients frequently have hyperhomocysteinemia, a putative risk factor for cardiovascular disease. Treatment with folate, B6 and B12 partially reduces hyperhomocysteinemia.
