The objective of the present study was to analyze the influence of the I/D polymorphism of the ACE gene on the outcome of microalbuminuria in essential hypertensive patients who were receiving antihypertensive treatment. One hundred thirty-six essential hypertensive patients who were <50 years old and had never previously received treatment with antihypertensive drugs were included in the study. During a 3-year period, patients received nonpharmacological treatment consisting of moderate salt restriction and a low-calorie diet they were obese, with or without a regimen of antihypertensive drugs based on beta-blockers or ACE inhibitors. Hydrochlorothiazide was added when necessary to maintain the blood pressure goal of <135/85 mm Hg. At the beginning of the study and at yearly intervals, systolic and diastolic blood pressures (SBP and DBP, respectively), 24-hour urinary albumin excretion (UAE), renal function, and biochemical profile measurements were made. The insertion/deletion (I/D) polymorphism of the ACE gene was determined through the use of polymerase chain reaction. The variables used in the statistical analysis were the measurements at the start of the study and the increase or decrease detected during the follow-up, estimated as individual specific regression line slope values. At baseline, no differences in blood pressure or UAE values were observed among genotypes. Likewise, the genotype or allele frequency was not significantly different between normoalbuminurics and microalbuminurics. After the 3 treatment years, significant reductions in SBP, DBP, and UAE were found (SBP 151.6+/-17.3 reduced to 137.2+/-14.3 mm Hg, P<0.001; DBP 96.6+/-8.9 reduced to 84.5+/-9.8 mm Hg, P<0.001; UAE 36.7+/-71.5 reduced to 28.3+/-78.6 mg/24 h, P<0. 05). The slopes of these parameters over time did not differ significantly among genotypes. The slope of SBP was the main factor related to the slope of logUAE (P<0.003). A significant positive correlation coefficient between the SBP and logUAE slopes was observed for the DD patients (r=0.57, P<0.0001) but was absent in patients carrying the I allele (II r=-0.03, P=NS; I/D r=0.01, P=NS). Follow-up studies should be used to achieve a better understanding of the impact of candidate gene polymorphisms on the development of hypertension-induced organ damage. Assessment of the I/D polymorphism of the ACE gene may identify subjects who require a greatly lowered blood pressure to prevent organ damage and to reduce hypertension-associated complications and death.

Moexipril (7.4-15 mg/day) was given to 34, spirapril (3-6 mg/day) -- to 18 postmenopausal women with hypertension and metabolic syndrome for 16 weeks. Hydrochlorthiazide was added when therapy was not sufficiently effective. Both angiotensin converting enzyme inhibitors had similar hypotensive activity: blood pressure normalized in 71 and 61% of moexipril and spirapril treated women, respectively. Both drugs promoted normalization of metabolism of lipid (lowering of levels of cholesterol, atherogenic lipoproteins and triglycerides) and carbohydrates (lowering of hyperinsulinemia). Patients with postmenopausal metabolic syndrome had elevation of leptin level up to 27.5+/-5.5 pg/ml. Moexipril and spirapril caused lowering of elevated levels of leptin. These drugs did not affect levels of sex hormones. They exerted vasoprotective (normalization of endothelium dependent and independent vasodilatation) and nephroprotective (attenuation and normalization of microalbuminuria) effects. Thus spirapril and moexipril are effective in treatment of hypertension in patients with postmenopausal metabolic syndrome.

A 62-year old woman with obesity, high blood pressure and type 2 diabetes mellitus (DM2) was referred to a Vascular Risk Unit of the Internal Medicine Department due to elevated HbA1C (8.1%) in spite of having taken metformin (850 mg/12h) and glipizide (10 mg/12 h) regularly. She tries to exercise daily (walking 30 min) and has lost weight (from 5 to 12 kg) several times, but always regains what she has lost. Furthermore, she monitors her glucose levels in fasting every two weeks and generally has between 120 and 160 mg/dL. Her high blood pressure is being treated with enalapril/HCTZ and she also takes aspirin 100mg/day and simvastatin 20 mg/day. It is seen in her family background that one brother died suddenly at 50 years of age. Her physical examination shows a BMI of 32.4 Kg/m(2), and she has no edemas in the lower limbs. Her BP is 154/82 mmHg and creatinine 0.9 mg/dL. She has no microalbuminuria and her liver function is normal. What treatment do you think would be the more appropriate? 1 - Add glitazones. 2 - Add incretin mimetics (GLP 1/ DPP-4). 3 - Slow acting insulin.
