Fasting serum insulin levels in essential hypertension. A meta-analysis.
UNLABELLED: BACKGROUND--The role of insulin in the genesis of essential hypertension remains an area of intense controversy. Most clinical evidence suggests a definite association. Several pathophysiologic mechanisms have been proposed. However, current data remain disparate and contradictory. METHODS--Meta-analysis allows data pooling of primary study findings and subsequent integration into a statistically meaningful outcome. This method was used to study the relationship in euglycemic individuals between blood pressure and fasting serum insulin level, age, body mass index, and fasting plasma glucose level. RESULTS: -A significant correlation was demonstrated between fasting serum insulin concentration and both systolic blood pressure and diastolic blood pressure. Age and body mass index also revealed meaningful associations. The meta-analytic correlation between plasma glucose level and both systolic blood pressure and diastolic blood pressure failed to achieve significance. CONCLUSIONS--Data from a meta-analytic review examining fasting serum insulin levels in euglycemic individuals demonstrate a significant correlation with systolic and diastolic blood pressure. This study supports the role of hyperinsulinemia in the pathogenesis of essential hypertension.

Effect of pro-atrial natriuretic peptides 1-30, 31-67 and 99-126 on angiotensin II-stimulated aldosterone production in calf adrenal cells.
Pro-atrial natriuretic peptide (Pro-ANP) is a 126 amino acid peptide from which atrial natriuretic peptide (ANP) (99-126 amino acid) is derived. ANP has potent diuretic, natriuretic and vasodilatory peptides. ANP is also a potent direct and indirect inhibitor of aldosterone secretion. The N-terminus of the ANP prohormone containing the peptides 1-30 and 31-67 have been demonstrated to have diuretic, natriuretic and vasodilatory properties. Dispersed calf zona glomerulosa cells were incubated with angiotensin II (A-II) and increasing concentrations of the ANP, ProANP 1-30 and 31-67 to determine if their reported natriuretic activity was mediated through suppression of aldosterone secretion. ANP as reported by many investigators produced a dose-dependent and potent inhibition of A-II-mediated aldosterone secretion. The Pro-ANP 1-30 and 31-67 did not affect A-II-stimulated aldosterone secretion at any of the doses tested. This study shows that the reported natriuretic effect of the fragments is not mediated by inhibition of aldosterone secretion.

Hypernephroma associated with multiple endocrine neoplasia type I: a case report.
We report a case of multiple endocrine neoplasia type I and hypernephroma. Parathyroid hyperplasia, adrenocortical hyperplasia, a nodular goiter, multiple lipomas, a chromophobe adenoma of the pituitary and hypernephroma had all been diagnosed previously. All but the last are features consistent with the diagnosis of multiple endocrine neoplasia type I (Wermer's syndrome). The association of multiple endocrine neoplasia type I and hypernephroma may represent a new manifestation of this pleiotropic syndrome.
