Abstract/OtherAbstract:
Recent studies give contradictory data regarding the role of hyperhomocysteinemia (hyperHcy) in cardiovascular (CV) morbidity and mortality in hemodialysis (HD) patients. The aims of the present study were to detect the most powerful variables associated with hyperHcy as well as to evaluate the relationship between hyperHcy and CV morbidity and mortality. The prospective follow-up study of 113 patients (52 males, aged 55.2+/-13.1 years) maintained by HD for 81.9+/-56.9 months at our Institute was carried out over 55 months. Fifty-seven (50.4%) of the examined patients were supplemented with water-soluble vitamins including folic acid and vitamin B complex pills or ampoules. Total serum Hcy level was determined by high-performance liquid chromatography, while serum folic acid and vitamin B(12) were measured by radioimmunoassay. The multivariate analysis showed HD duration (r=0.608; P=0.02) and folic acid serum level (r=-0.580; P=0.03) to be significant predictors of serum tHcy concentration. The multivariate Cox regression analysis of CV mortality revealed diabetes mellitus and heart failure as the most powerful positive predictors, while creatinine, albumin and vitamins intake therapy were negative predictors of CV mortality. Long-term supplementation with the usual doses of vitamins is followed with increased survival in hemodialysis patients. Although total serum Hcy level was not found to be a predictor of overall and CV mortality, the role of hyperHcy. as risk factor for CVD cannot be excluded in hemodialysis patients.
