5-methyltetrahydrofolate Survival and Inflammation in ESRD Patients

Summary

A randomized prospective study was done to determine whether i.v. 5-methyltetrahydrofolate vs oral folate improved survival in ESRD patients. Homocysteine, CRP, Lp(a), albumin, folates, vitamin B6 and B12 were checked. The 5-MTHF treated group was associated with lowered C reactive protein and higher survival than the folate treated group.
