Abstract:
The K ir6.2 E 23 K polymorphism was studied with a special reference to secondary sulfonylurea ( SU ) failure in non‐obese patients with type 2 diabetes. Materials and Methods We recruited 278 non‐obese (body mass index ≤30.0 kg/m 2 ) Japanese patients with type 2 diabetes who had a history of SU treatment (for 11.2 ± 6.3 years) and compared the frequency of the secondary SU failure among the genotypes of the polymorphism. Genotyping of the K ir6.2 E 23 K was carried out by polymerase chain reaction‐restriction fragment length polymorphism. Results The genotype frequencies of the polymorphism were similar to those previously reported in Japanese patients with type 2 diabetes. The frequency with which patients deteriorated into secondary SU failure was significantly higher in those with the KK genotype than those with EE or EK genotypes. Among 214 patients who eventually received insulin therapy because of secondary SU failure, the period of SU treatment in those with the KK genotype was significantly shorter than those with the EE or EK genotype, although the period from diagnosis to the start of SU treatment was not significantly different. Conclusions These data suggest that the K ir6.2 E 23 K polymorphism is related to the acceleration of secondary SU failure in non‐obese Japanese patients with type 2 diabetes.
