Butyrylcholinesterase activity and risk factors for coronary artery disease.

The aim of this study was to verify which risk factors for coronary artery disease (CAD) are independently correlated with butyrylcholinesterase (BChE) activity. We studied 88 White individuals (43 males) aged 47.3+/-15.7 years (mean+/-SD; range: 14.0-80.0 years) including 38 with hyperlipidemia, 30 with hypertension and 5 with diabetes mellitus (DM). Simple correlation analysis showed that BChE activity was positively correlated with age, sex, body mass index, hypertension and DM, as well as with triglycerides (TGs), total cholesterol, low-density lipoprotein cholesterol and apolipoprotein B (Apo B). However, after a step-wise multiple regression analysis, the only risk factors for CAD that showed independent correlations with BChE activity were, in descending order of importance, Apo B, TGs and DM. Our findings seem to reinforce suggested associations of BChE activity with lipoprotein synthesis and with hypertension, as well as supporting previous data on the relation of BChE activity with disturbances found in diabetes mellitus.

An improved method for butyrylcholinesterase phenotyping.

An improved method for the identification of butyrylcholinesterase phenotypes is proposed. It is based on modifications of a method that uses alpha-naphthyl acetate as substrate and DL-propranolol and Ro2-0683 as inhibitors. The proposed modifications make the method more rapid and increase the accuracy of the determinations of the phenotypes tested (BCHE U, BCHE UF, BCHE UA, BCHE AK, BCHE AF, and BCHE A). These modifications make the method even more adequate for population studies and clinical routine.

The C5 isozyme of serum cholinesterase and adult weight.

The relationship between the CHE2 locus of serum cholinesterase (BChE) and adult human weight was studied in a sample of 225 CHE2 C5+ individuals and 225 CHE2 C5- controls matched for sex, height, age and race. With respect to the intensity of the C5 band staining (scored 1-6), 113 individuals had faint C5 bands (scores 1-3) and 112 intense C5 bands (scores 4-6). The individuals with intense CHE2 C5+ phenotype showed a significantly lower mean adult weight (64.66 +/- 0.73 kg) when compared to their controls (70.59 +/- 0.97 kg) and a significant reduction in weight variance (59.81 and 105.18, respectively). Individuals with faint C5 bands, although showing a negative correlation between weight and C5 band intensity, did not differ from their controls in mean weight.
