Abstract
Background/Aims: Apolipoprotein B polymorphism plays an important role in the metabolism of cholesterol. And bile acids, which may be related to the development of colorectal adenomas, An association between apolipoprotein B genotype and colonic adenomas bas been reparted in a western country. This study was designed to determine whether the apolipopratein S was genotype would be associated with proximal or distal colonic adenomas in Koreans. Methods: On the colonoscopy, colonic adenomas were found in 132 patients. Proxima1 colonic adenoma was found in 35 patients and distal colonic adenoma was found in 97 patients. Serum leveis of total cholesterol, LDL-cholesterol, HDL-cholesterol and trlglyceride were measured. Apolipoprotein E genotype was determined by PCR and allele specific oligonucleotide hybridization. 279 contro1 subjects without an adenoma on the screening sigmoidoscopy were se1ecfed randomly. Results: The serum levels of total choles0'rol, LDL-cholesterol, HDL-cholesterol and triglyceride did not significantiy differ between each adenoma group and control group. The individual frequencies of ε2, ε3 and ε4 alleles in patients with colonic adenomas did not differ from those in control subjects. The frequency of either heterozygote or homozygote for g 4 allele in patients with proximal adenoma was lower than that in control subjects (0.029 vs O.I68, p < 0.05). Conclnsions: The data suggest that g 4 allele may be associated with a lower risk for the development of proximal colonic adenoma in Korean men. (Korean J Gastroiuteat Endosc 2001;23:14-20)
