Abstract Part 1: Which mutations are causing mild hyperhomocysteinemia? Mild hyperhomocysteinemia is a risk factor for arterial as well as venous occlusions. Both genetic and acquired factors are known to influence the plasma homocysteine concentration. Different family studies reveal that the plasma homocysteine concentration is strongly influenced by genetic components. Until now we have discovered two mutations in the methylene tetrahydrofolate reductase gene which are genetic causes of mild hyperhomocysteinemia. The folate status is strongly influencing this phenotype/genotype relation (nature/nurture). These mutations can only explain a very small part of the genetic component of mild hyperhomocysteinemia. By use of different molecular genetic techniques genes involved in homocysteine metabolism will be investigated for homocysteine increasing mutations.

Compare the efficacy of two doses of folic acid in normalizing plasma total homocysteine concentration in patients with end stage renal disease receiving regular hemodialysis therapy resulting in hyperhomocysteinemia. II. Determine the requirement of co-supplementation with extra pyridoxine (vitamin B6) and cyanocobalamin (vitamin B12) daily in these patients. III. Assess the safety and tolerability of this therapy in these patients. Condition Intervention End Stage Renal Disease

To assess the risk of venous thrombosis associated with hyperhomocysteinemia, we studied plasma homocysteine levels in patients with a first episode of deep-vein thrombosis and in normal control subjects. Methods We measured plasma homocysteine levels in 269 patients with a first, objectively diagnosed episode of deep-vein thrombosis and in 269 healthy controls matched to the patients according to age and sex. Hyperhomocysteinemia was defined as a plasma homocysteine level above the 95th percentile in the control Results Of the 269 patients, 28 (10 percent) had plasma homocysteine levels above the 95th percentile for the controls, as compared with 13 of the controls (matched odds ratio, 2.5; 95 percent

(March 21 issue) supports our finding that hyperhomocysteinemia is a risk factor for deep-vein thrombosis that is independent of coexisting abnormalities of naturally occurring anticoagulants. This important confirmation challenges the suggestion by Mandel et al., in their article in the same issue, that hyperhomocysteinemia increases the risk of thrombosis only if the elevation in homocysteinemia is associated with the presence of factor V Leiden. Unlike our study of patients with early-onset deep-vein thrombosis and their previous study of patients with recurrent deep-vein thrombosis

Extractions: Homocysteine is an amino acid derived from methionine (an essential amino acid). Amino acids are the building blocks of proteins. Elevated homocysteine levels (hyperhomocysteinemia) have been found to increase the risk of venous thrombosis up to fourfold. According to one multicenter study, high blood levels of homocysteine are associated with early onset of vascular disease and venous thrombosis (1025%) and with recurrence (19%) of deep venous thrombosis after 2 years. High homocysteine levels in people who have no symptoms can be normalized with supplements of folic acid, vitamin B , and vitamin B (although the benefit is not proved). Patients who have had deep venous thrombosis should have anticoagulation therapy with warfarin or low molecular weight heparin. The physician determines the duration of this treatment. Lifelong anticoagulation may be considered for patients with a high risk for recurrent deep venous thrombosis.
