AIM: The aim of this study was to determine the prevalence of hyperhomocysteinemia in a population with peripheral vascular occlusive disease in Kuwait. METHODS: From November 2000 to May 2002, total serum homocysteine levels were measured in 172 consecutive patients admitted to the vascular surgery unit because of peripheral vascular arterial disease. A fluorescence polarization immunoassay was used for measuring total serum homocysteine levels. Serum homocysteine levels over 15 mol/L were considered as high. RESULTS: The mean ankle-brachial index was 0.59+/-0.2 and 0.55+/-0.2 for right and left legs, respectively. The mean serum homocysteine level was 14.9+/-4.7 mol/L (range, 4.2-50.0). High homocysteine levels were found in 70 out of 172 patients (40.7%). The prevalence of hyperhomocysteinemia was significant in patients with hypertension (P=0.03) and ischaemic heart disease (P=0.04). Binary logistic regression model showed that male gender, diabetes mellitus and hypertension were significant independent predictors for high levels of homocystinemia in peripheral vascular occlusive disease [adjusted odds ratio (OR) 2.90; 95% confidence interval (CI); 1.18-7.12; P=0.02]; [0.35 OR; 95% CI; 0.15-0.79; P=0.01] and [2.12 OR; 95% CI; 0.98-4.59; P=0.05], respectively. Diabetes was significant but appeared to protect for peripheral vascular occlusive disease in patients with high levels of serum homocysteine. CONCLUSION: Elevated homocysteinemia was found in 40.7% of patients suffering from peripheral vascular disease. In this cohort, male gender, diabetes and hypertension were found to be risk factors along with elevated homocysteine levels.
