Addition of Modulators of Homocysteine to Adalimumab Therapy in the Treatment of Moderate to Severe Plaque Psoriasis

Summary

Vitamins modulating homocysteine affect both TNF-alpha, vascular endothelial growth factor, and theoretically enhance the anti-inflammatory version of NOS thus hopefully increasing the efficacy and reducing the chance of some toxicities of adalimumab as determined by blood testing and EKGs.
