Ukkola O, Kesäniemi YA (University of Oulu, Oulu, Finland). Preproghrelin Leu72Met polymorphism in patients with type 2 diabetes mellitus. J Intern Med 2003; 254: 391–394. Objectives. The association between the Leu72Met polymorphism of the preproghrelin gene and diabetic complications was examined in patients with type 2 diabetes mellitus. Subjects and methods. A total of 258 patients with type 2 diabetes mellitus and 522 control subjects were screened. Genotypes were determined by polymerase chain reaction technique. The diagnosis of coronary heart disease was based on clinical and ECG criteria. Laboratory analyses were carried out in the hospital laboratory. Results. No differences in the genotype distributions and allele frequencies of the preproghrelin Leu72Met polymorphism were found between type 2 diabetes mellitus patients and controls. The polymorphism was not associated with macro‐ or micro‐angiopathy or hypertension. However, Leu72Met polymorphism was associated with serum creatinine ( P = 0.006) and lipoprotein(a) [Lp(a)] levels ( P = 0.006) with Leu72Leu subjects showing the highest values. This association was observed only amongst diabetic group. Conclusions. The Leu72Met polymorphism of the preproghrelin gene was not related to cardiovascular disease in type 2 diabetes mellitus patients. Leu72Met polymorphism was, however, associated with serum creatinine and Lp(a) levels in diabetic patients. The mechanism might be associated with a possible change in ghrelin product and its somatotropic effect.
