Homocysteine screening of a female Hispanic population.
A total of 821 women of Hispanic descent aged 21-65 years, were screened for total and high density lipoprotein (HDL) cholesterol through outpatient clinics and public screening. Of this group, 78 were invited back for further testing because they had a total cholesterol/HDL cholesterol ratio exceeding 4.5 indicative of high risk for cardiovascular disease. Written consent and a fasting blood sample was obtained from these women, and tested for serum homocysteine. The concentrations for 77 of the 78 women (mean 8. 40+/-2.24, range 4.21-13.99 micromol/l) were within the pre-established normal range for women. One subject had an exceptionally high homocysteine concentration of 137 micromol/l. This subject subsequently developed a stroke and has been institutionalized since that time. Blood from the subject and immediate family members were tested for the 5'-10'-methylenetetrahydrofolate reductase (MTHFR) polymorphism. The subject and her children were both hyperhomocysteinemic and heterozygous for the mutation. One of the children also had a low vitamin B12 concentration in blood. Although the high homocysteine and cardiovascular risk in these subjects were likely due to a dietary deficiency of the vitamins, the MTHFR mutation may have also been a contributing factor. With the availability of rapid assays, screening blood for homocysteine in subjects deemed at high risk for cardiovascular disease may be justified.
