Table 2.
Glucose status in patients with PA and matched controls, classified according to the presence or absence of hypokalemia.
| Control (N = 212) | PA with hypoK (N = 73) | p | Control (N = 604) | PA without hypoK (N = 213) | p | |
|---|---|---|---|---|---|---|
| Pre-diabetes, N (%) | 49 (23.1%) | 23 (31.5%) | 0.155 | 151 (25.0%) | 80 (37.6%) | <0.001 |
| DM, N (%) | 27 (12.7%) | 19 (26.0%) | 0.008 | 80 (13.2%) | 37 (17.4%) | 0.139 |
| Hyperglycemia, N (%) | 76 (35.8%) | 42 (57.5%) | 0.001 | 231 (38.2%) | 117 (54.9%) | <0.001 |
Up to three controls were enrolled per participant with PA. They were individually matched for sex, age (±1 year), and BMI (±0.5 kg/m2). Hypokalemia was defined by a serum potassium concentration < 3.5 mEq/L. The hyperglycemia was defined as DM or pre-diabetes. Significant results (p < 0.05) are indicated in bold. BMI, body mass index; DM, diabetes mellitus; FPG, fasting plasma glucose; hypoK, hypokalemia; PA, primary aldosteronism.
