Hyperhomocysteinemia is considered an independent risk factor for atherosclerosis, atherothrombosis and Venous ThromboEmbolism (VTE) [1], [2] and [3]. Normal total plasma homocysteine concentrations range from 5 to 15 μmol/L in the fasting state. Hyperhomocysteinemia is classified as moderate (homocysteine concentration, 15 to 30 μmol/L), intermediate (> 30 to 100 μmol/L), and severe (> 100 μmol/L) on the basis of concentrations measured during fasting. Although severe hyperhomocysteinemia is rare, mild hyperhomocysteinemia occurs in approximately 5% to 7% of the general population. In this case, patients are typically asymptomatic until the third or fourth decade of life when premature Cor…
Elevated cerebrospinal fluid and plasma homocysteine levels in ALS
2009
Background: High cerebrospinal fluid (CSF) and plasma levels of homocysteine (HC) have been reported in certain neurodegenerative disorders, such as Alzheimer’s, Parkinson’s diseases and, recently, amyotrophic lateral sclerosis (ALS). Objectives: To assay the CSF and plasma levels of HC in ALS patients and controls, and to evaluate the relationship between HC levels and clinical variables of the disease. Methods: Cerebrospinal fluid from sixty-nine (M/F 1.87) and plasma from sixty-five ALS patients (M/F 1.83) were taken and stored at −80°C until use. Controls (CSF = 55; plasma = 67) were patients admitted to our hospital for neurological disorders with no known relationship to HC changes…
