Discrepancies in the diagnosis of hypertension in adolescents according to available office and home high blood pressure criteria.

This study aimed at comparing the prevalence of abnormal blood pressure (BP) phenotypes among 241 adolescents referred for hypertension (15.4 ± 1.4 years, 62% males, 40% obese) according to mostly used or available criteria for hypertension [AAP or ESH criteria for high office BP (OBP); Arsakeion or Goiânia schools' criteria for high home BP monitoring (HBPM)]. High OBP prevalence was greater when defined by AAP compared with ESH criteria (43.5% vs. 24.5%; p < .001), while high HBPM prevalence was similar between Arsakeion and Goiânia criteria (33.5% and 37.5%; p = .34). Fifty-five percent of the sample fulfilled at least one criterion for high BP, but only 31% of this subsample accomplished all four criteria. Regardless of the HBPM criteria, AAP thresholds were associated with lower prevalence of normotension and masked hypertension and greater prevalence of white-coat and sustained hypertension than ESH thresholds. These findings support the need to standardize the definition of hypertension among adolescents.

Does nutritional status interfere with adolescents' body image perception?

Adolescents' body image (BI) may not match their nutritional status. This study selected representative sample of healthy adolescents aged between 12 and 18 from public and private schools. Anthropometric measures were performed in order to calculate the body mass index (BMI) percentile. The silhouette scale proposed by Childress was used to evaluate BI, making it possible to assess BI satisfaction and BI distortion. The sample was composed of 1168 adolescents with a mean age of 14.7 years; 52.9% were female, 50.9% were fair-skinned, 62.4% had consumed or still consume alcohol and 67% attended public school. Male adolescents presented more overweight and obesity (28.4%) (p<0.05) than the female (17.1%). It was observed that 69.4% were dissatisfied with BI, 91.1% of the obese and 69.8% of those with overweight wished to lose body weight and 82.5% of those underweight wished to gain body weight. BI distortion was identified, since 35% of the adolescents who were underweight did not regard themselves thin, 39.1% of the overweight individuals and 62.1% of the obese did not see themselves in their adequate classifications. Adolescents with overweight/obesity were those who presented higher dissatisfaction with BI, mainly the females. Male individuals presented a greater wish of gaining weight. BI distortion was present in adolescents of all classes of BMI percentile.

A high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using solid phase extraction for the simultaneous determination of plasma concentrations of enalapril and enalaprilate in hypertensive patients treated with different pharmaceutical formulations.

UNLABELLED: Enalapril maleate, available on the market in a variety of different pharmaceutical formulations, is commonly used for the control of systemic arterial hypertension. Many therapeutical failures have been reported thus far in clinical practice with respect to switching between different pharmaceutical formulations of the same product during pharmacological therapy. In the present study, plasma concentrations of enalapril and enalaprilate were measured in hypertensive patients undergoing treatment with different pharmaceutical formulations. MATERIALS AND METHODS: Pharmaceutical formulations studied included the reference brand product, a generic formulation, and a third drug product marketed as "similar"; plasma samples were obtained from 30 hypertensive volunteer patients. Drug was extracted from the plasma by solid phase extraction and determined by liquid chromatography-tandem mass spectrometry. The method was validated for the main analytical parameters. RESULTS: The analytical method developed in this study, using liquid chromatography-tandem mass spectrometry, was confirmed as suitable for application in the determination of plasma concentrations in patients and subsequently revealed statistically significant differences in plasma concentrations between the 3 treatment groups. CONCLUSIONS: Such differences reinforce the hypothesis that the bioequivalence tests currently proposed by the regulatory authorities to promote interchangeability between pharmaceutical formulations may not in fact represent a definitive parameter for guaranteeing similar plasma concentrations.

Hypertensive diabetic patients: guidelines for conduct and their difficulties.

OBJECTIVE: To assess the effect of blood pressure (BP) control and other cardiovascular risk factors in patients with diabetes mellitus in a referral service for the treatment of hypertension. METHODS: A retrospective study where diabetic patients (at least 2 fasting glucose levels above 126 mg/dL, use of hypoglycemic agents or insulin, or both of these) were included. They were evaluated at the first appointment (M1) and at the last appointment (M2), regarding blood pressure, body mass index (BMI), use of hypertensive drugs, glycemia, total cholesterol (TC), creatinine, and potassium. RESULTS: Of 1,032 patients studied, 146 patients with a mean age of 61.6 years had diabetes, and 27 were men (18.5%). Mean follow-up was 5.5 years. BP values were 161.6 x 99.9 mmHg in M1 and 146.3 x 89.5 mmHg in M2. In M1, 10.4% of the patients did not use medications, 50.6% used just 1 drug, 30.8% used 2 drugs, and 8.2% used 3 or more drugs. In M2, these values were 10.9%, 39%, 39.7%, and 10.4%, respectively. Diuretics were the most commonly used medication, whereas angiotensin-converting enzyme inhibitors (ACE inhibitors) were those drugs which presented greater increase when comparing M1 to M2 (24.6% and 41.7%, respectively). Only 17,1% reached the recommended goal (BP<130x85 mmhg). The other cardiovascular risk factors did not change significantly. CONCLUSION: Our data reinforce the necessity of a more aggressive approach in the treatment of these patients, despite the social and economic difficulties in adhering to treatment.
