The conflicting results of several studies suggest that there is an association between the butyrylcholinesterase-K variant (BCHE-K, G1615A/Ala539Thr) and the risk of developing coronary artery disease (CAD) in diabetes and non-diabetic subjects. The objective of this study was to determine whether the presence of the BCHE-K variant exacerbates the risk of CAD in patients from western Iran with and without type 2 diabetes mellitus (T2DM). This case-control study comprised 464 subjects undergoing their first coronary angiography. They were matched and randomly assigned into four groups: CAD+T2DM+ (CAD/T2DM), CAD+DM(-) (CAD/ND), CAD(-)DM+ (T2DM/NCAD) and CAD(-)DM(-)(control). The BCHE-K variant was detected by PCR-RFLP. The BCHE-K allele frequency in CAD patients with and without T2DM [total CAD (TCAD)] and separately for each group (CAD/T2DM and CAD/ND) was significantly higher than in the control group (21.1 % versus 13.3 % (p = 0.001), 22.4 % versus 13.3 % (p = 0.001) and 19.7 % versus 13.3 % (p = 0.015), respectively). The odds ratios (ORs) for the BCHE-K heterozygous and homozygous variants in TCAD subjects were 1.65 (95 % CI 1.17-2.3; p = 0.004) and 4.3 (1.05-19.4; p = 0.048); for CAD/T2DM individuals 1.76 (1.2-2.6; p = 0.004) and 4.73 (0.96-23.3; p = 0.052); and for CAD/ND patients 1.53 (1.05-2.3; p = 0.029) and 3.88 (0.8-19.7; p = 0.7), respectively. The OR of the BCHE-K allele was found to be 1.74 (1.1-2.4; p = 0.001) in TCAD subjects, 1.87 (1.12-1.48; p = 0.001) in the CAD/T2DM group and 1.59 (1.04-1.4; p = 0.016) in CAD/ND subjects. These data suggest that the BCHE-K allele increases the risk of CAD in the population (with and without DM) in western parts of Iran, and its presence intensifies the risk of CAD in T2DM. The fact that the BCHE-K allele, even in the heterozygous form, exacerbates the risk of CAD in this population, suggests that a specific therapeutic intervention should be considered for this particular group of patients.

We have previously shown that butyrylcholinesterase-K (BCHE-K, G1615A/Ala539Thr) variant increases the risk of coronary artery disease (CAD). In addition, we have found that the presence of APOE-epsilon 4 allele augments the risk of CAD in patients with type II diabetes mellitus (T2DM/CAD). Here we explored the concomitant presences of two alleles of the BCHE-K and APOE-epsilon 4 in increasing the risk of CAD or diabetes in T2DM patients with or without CAD and CAD patients without T2DM. This case-control study comprised 631 subjects undergoing their first coronary angiography. They were matched and randomly assigned into four groups: type II diabetic patients with no sign of CAD (T2DM), type II diabetic patients with CAD/ND (T2DM/CAD), CAD patients with no sign of diabetes (CAD/ND), and healthy individuals (NCAD/ND). BCHE-K variant and APOE genotypes were detected by PCR-RFLP and serum lipid level was measured enzymatically. We found that BCHE-K and APOE-epsilon 4 allele act synergistically to increase the risk of CAD in both T2DM, non-diabetic and total CAD (TCAD = T2DM/CAD + CAD/ND) individuals. The level of synergy 1.5 and 1.2 fold are higher in CAD patients (OR = 4.5; P = 0.011) with T2DM than the non-diabetic CAD patients (OR = 3.07; P = 0.024) and TCAD patients (OR = 3.74; P = 0.018), respectively. The CAD subjects with and without T2DM and TCAD patients carrying both APOE-epsilon 4 allele and BCHE-K had significantly lower plasma HDL-C (P values = 0.008, 0.047, and 0.036, respectively) and higher plasma LDL-C (P values = 0.025, 0.048, and 0.04, respectively), than that of the control carriers both APOE-epsilon 4 and BCHE-K. We have found that BCHE-K and APOE-epsilon 4 allele not only act synergistically to increase the risk of CAD, particularly in T2DM subjects in population from western Iran, who have high levels of LDL-C and low levels of HDL-C, suggesting that a specific therapeutic intervention should be considered for these particular groups of patients.
