title: An inverse correlation between serum leptin levels and hemoglobin A1c in patients with non-insulin dependent diabetes mellitus.
abstract: We measured serum leptin concentrations in 70 patients with diabetes mellitus to investigate the relationship between serum leptin levels and glycemic control. A positive correlation between serum leptin levels and body mass index or plasma insulin was obtained as reported previously. The present study also demonstrated an inverse association of serum leptin levels with hemoglobin A1c (HbA1c). Multiple regression analysis revealed that HbA1c was an independent determinant of serum leptin levels. These results suggest that HbA1c may be a factor to influence serum leptin levels and that hyperglycemia for a long period or poorly controlled diabetes may reduce leptin levels.
