A number of abnormalities in calcium homeostasis have been reported in patients with essential hypertension. IN turn, insulin has been shown to influence the activity of the Ca(2+)-ATPase. We have previously shown that normotensive offspring of essential hypertensive individuals have an exaggerated insulin response to a glucose overload. Therefore, the aim of the present study was to evaluate basal and calmodulin-activated Ca(2+)-ATPase in red blood cells and its relationship to the insulin response during an intravenous glucose tolerance test in 27 normotensive adolescents with a family history of essential hypertension (F+) (mean age, 13.9 +/- 0.5 years) and in 10 control subjects matched for age and body mass index with no family history of hypertension (F-). The results (mean +/- SD) were as follows (mumol Pi/[mg protein/h]10(-1)): basal Ca(2+)-ATPase, 4.5 +/- 1.2 in F+ and 5.1 +/- 1.6 in F- (P = NS); calmodulin-activated Ca(2+)-ATPase, 13.6 +/- 3.9 in F+ and 16.2 +/- 1.7 in F- (P < .04). The insulin area under the curve after the glucose load was 3413 +/- 1674 microU/mL per hour in F+ and 2752 +/- 928 in F- (P = NS). Calmodulin-activated Ca(2+)-ATPase showed a negative correlation with the insulin area under the curve (r = -.59, P < .005) and cholesterol levels (r = -.38, P < .03). Urinary calcium excretion was 1.82 +/- 0.9 mmol/d in F+ and 2.47 +/- 0.9 mmol/d in F- (P = NS).(ABSTRACT TRUNCATED AT 250 WORDS)
