Serum homocysteine is associated with the severity of primary chronic venous disease

ObjectiveThis study was conducted to assess whether serum homocysteine concentration was associated with the severity of primary chronic venous disease.DesignCross-sectional study.MethodsA total of 282 primary chronic venous disease patients were enrolled from outpatient vascular services. The severity of venous disease was graded using the Clinical Etiology Anatomy Pathophysiology classification system. The association of serum homocysteine concentration with advanced primary chronic venous disease (C4-6) was assessed using the Mann Whitney U test and logistic regression analysis.ResultsMedian (interquartile range) serum homocysteine concentrations were 9.10 µM (7.55–10.75) and 10.40 µM (8.85–13.10) in patients with primary chronic venous disease classified by C1-3 (n = 209) and C4-6 (n = 73) grades, respectively, p < 0.001. Serum homocysteine concentration was positively associated with clinical grade 4–6 after adjusting for other risk factors including age, diabetes, male sex, hypertension, recurrent v...
