Abstract

Bariatric surgery significantly reduces the risk of cardiovascular diseases but has no effects on hyperhomocysteinemia, the risk factor for atherogenesis. We hypothesize that the decrease in serum betaine (involved in homocysteine metabolism) concentrations, after bariatric surgery, impairs conversion of homocysteine to methionine, leading to hyperhomocysteinemia. If this is true, it may be desirable to supply patients after bariatric surgery with betaine. Serum betaine and homocysteine concentrations were measured by liquid chromatography/mass spectrometry, in 16 obese patients, before and 6 months after bariatric surgery. Ten healthy individuals with normal body mass index served as controls. Serum betaine concentrations decreased to the values lower than in controls after bariatric surgery, whereas serum homocysteine concentrations remained elevated. In patients supplemented with B₁₂ and folate, no effect of bariatric surgery on serum concentrations of vitamins involved in homocysteine metabolism was observed. These results suggest that betaine deficit could be responsible for maintenance of hyperhomocysteinemia after bariatric surgery. We postulate that supplementation with betaine could be of therapeutic value for the treatment of hyperhomocysteinemia after bariatric surgery.
