Hyperinsulinemia as a determinant of microalbuminuria in essential hypertension

OBJECTIVE To analyze the relationship between insulinemia and urinary albumin excretion in a group of nonobese, young adult hypertensive patients, who had never been treated with antihypertensive drugs. PATIENTS AND METHODS Forty-nine patients who fulfilled the inclusion criteria were included. Twenty-four-hour ambulatory blood pressure monitorings, urinary albumin excretion (UAE) measurements, and an oral glucose-tolerance test measuring glucose and insulin, were performed, and left ventricular mass was measured by echocardiography. Hypertensive patients were classified as normoalbuminuric when their UAE was < 30 mg/24 h (40 patients; mean UAE 13.4 +/- 7.0 mg/24 h), and as microalbuminuric…

Factors Related to the Occurrence of Microalbuminuria During Antihypertensive Treatment in Essential Hypertension

The objective of the study was to assess the factors related to the occurrence of microalbuminuria during the follow-up of a young adult group with essential hypertension that had not been previously treated. Normo-albuminuric essential hypertensives, &lt;50 years old, who had not been previously treated with antihypertensive drugs and who did not have diabetes mellitus were included. After the initial evaluation, patients were treated using only nonpharmacological measures (n=62), β-blockers (n=38), ACE inhibitors (n=64), calcium channel blockers (n=8), and several classes (n=15). Measurements were taken for office blood pressure, biochemical profile, and 24-hour urinary albumin excretion…

Determinants of urinary albumin excretion reduction in essential hypertension: A long-term follow-up study.

The objective of the present study was to assess factors related to long-term changes in urinary albumin excretion (UAE) of nondiabetic microalbuminuric (n = 252) or proteinuric hypertensive individuals (n = 58) in a prospective follow-up.After enrollment, patients were placed on usual care including nonpharmacological treatment and/or treatment with an antihypertensive drug regime to achieve blood pressure135/85 mmHg. Periodic UAE measurements were performed until regression or significant reduction (defined when UAE dropped50% from the initial values, plus reduction of UAE to30 mg/24 h for microalbuminuric patients and300 mg/24 h for proteinuric patients).Among the microalbuminuric patien…

Estudio de los factores relacionados con los cambios en la microalbuminuria durante el tratamiento antihipertensivo

Fundamento Conocer los factores que determinan los cambios en la microalbuminuria (mAlb)durante el tratamiento antihipertensivo en pacientes con hipertension arterial (HTA) esencial. MeTodos Se incluyeron 106 pacientes hipertensos esenciales (57 varones; edad media (DE) de40,8 [6,6] anos) no diabeticos y nunca tratados con farmacos antihipertensivos. Se determinaronvalores de presion arterial, perfil bioquimico y excrecion urinaria de albumina (EUA) medianteinmunonefelometria en dos muestras de orina de 24 h. Los pacientes se asignaron alazar a recibir tratamiento, de forma que 53 pacientes se trataron con inhibidores de la enzimaconversiva de la angiotensina (IECA), y 53 con bloqueadores b…

Polymorphism insertion/deletion of the ACE gene and ambulatory blood pressure circadian variability in essential hypertension

OBJECTIVE The objective of the present study was to analyze the influence of the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme on ambulatory blood pressure values and circadian variability in untreated patients with hypertension. MATERIAL AND METHODS Ninety-nine essential hypertensive patients, less than 50 years old (mean age 39.5+/-7.0 years), previously untreated with antihypertensive drugs were included. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed with a Spacelabs (90202 and 90207) monitor, during a regular working day in unrestricted ambulatory conditions. The I/D polymorphism of the ACE was determined by PCR. RESULTS The dist…
