Hyperglycemia in patients with primary aldosteronism / 中国医师杂志

ABSTRACT

Objective To investigate the prevalence of hyperglycemia in patients with primary aldosteronism.Methods Thirty two patients diagnosed as primary aldosteronism(PA) in our hospital from 2010 to 2013 (PA group),and 40 patients as essential hypertension (EH group).Two groups were measured and compared,including blood pressure,plasma aldosterone,urine aldosterone,and plasma potassium.Oral glucose tolerance test (OGTT) was performed and homeostasis model assessment-insulin resistance index(HO-MA-IR) were calculated.Results The prevalence of hyperglycemia was 43.75％ in PA group,including 25％ patients of glucose intolerance and 18.75％ patients of diabetes mellitus,which was significantly higher than those of EH group (25％,12.5％,and 12.5％,respectively).PA group's fasting and 2-hour postprandial insulin levels and insulin resistance index were higher than that of EH group.Conclusions The present study indicated that patients with PA had a significantly high prevalence of glucose metabolism disturbance and insulin resistance.Screening test should be performed and avoid missed diagnosis.
