ABSTRACT
Circulating liver membrane antibodies (LMAb) were examined in 71 patients with non-insulin-dependent diabetes mellitus (NIDDM) without liver dysfunction and 16 cases of KK mouse as a model of obese diabetic animals. LMAb were detected in 10 NIDDM patients (14.1%). Fasting blood glucose, glycosylated serum albumin (G-Alb), and glycosylated hemoglobin A1 (HbA1) levels were compared with LMAb-positive and negative groups. The G-Alb levels and HbA1 levels of the LMAb-positive group were significantly higher (p less than 0.05 and p less than 0.01, respectively) than those of the LMAb-negative group. In addition, there were no differences in histological findings in KK mouse liver between the LMAb-positive and negative cases. These results revealed that the state of continued high blood glucose directly or indirectly influence the autoimmunity and clinical features of NIDDM patients.
