RESUMO
OBJECTIVE: Poor oral health has previously been related to high body mass index (BMI). We aimed at exploring the link between BMI and several oral health markers, after adjustment for dietary patterns and plasma insulin, both of which could act as mediators. SUBJECTS AND METHODS: Dental examination was performed in a sample of 186 French subjects aged 35-64 years and selected from the general population to assess number of missing teeth, periodontitis, clinical attachment loss (CAL), probing pocket depth (PD), gingival index (GI) and plaque index (PI). Data collection also included a food-frequency questionnaire. BMI (considered as outcome variable) was categorized into quartiles, and as BMI<25; 25 ≤BMI<30; and BMI ≥ 30 kg m(-2) . RESULTS: After adjustment for age, gender, education level, smoking, physical activity, energy intake and C-reactive protein, BMI was statistically associated with missing teeth, PD and PI, but not with CAL, GI or periodontitis. After additional adjustment for 'high-carbohydrate' diet and plasma insulin or HOMA (homeostasis model assessment) index for insulin resistance, the statistical relationship between BMI and oral variables remained significant only for PD and PI. CONCLUSIONS: Plaque index, reflecting dental plaque, and PD, closely linked with periodontal inflammation and infection, are statistically associated with high BMI and obesity, independently of dietary patterns and insulin resistance.

AIM: To assess whether reverse-dipping status is associated with cardiovascular (CV) events such as CV death, myocardial infarction (MI) or stroke in diabetic patients with hypertension. METHODS: A total of 97 diabetic patients underwent their first ambulatory blood pressure monitoring (ABPM 1). "Reverse dippers" were defined as patients with a nighttime systolic and/or diastolic blood pressure (BP) greater than daytime systolic and/or diastolic BP. Other patients were called "others". A second ABPM (ABPM 2) was done after a median delay of 2.6 years. Patients were then followed for a further 2.9-year median period (total median follow-up: 5.5 years). RESULTS: After ABPM 1, CV events occurred in 53% of the reverse dippers (n=15) and in 29% of the others (n=82). Kaplan-Meier curves showed significant differences between the two groups (P=0.003). Mean nighttime systolic BP on ABPM 1 was 148+/-23 mmHg and 142+/-19 mmHg in patients who did and did not experience a CV event, respectively. With Cox analysis adjusted for confounders, a 10 mmHg increase in nighttime systolic BP was associated with a 35% increase in the risk of a CV event (hazard ratio [HR]: 1.35, P=0.003). The HR for a CV event in reverse- versus nonreverse-dipping status was 2.79 (P=0.023). After ABPM 2, the relationship between the reverse-dipping status and occurrence of CV events was no longer evident (P=0.678). Nighttime systolic BP remained predictive of CV events (P=0.001). CONCLUSION: These findings suggest that nighttime systolic BP per se appeared to be a stronger predictor of an excess risk of CV events compared with reverse-dipping status.

Alzheimer's disease (AD) is the most frequent form of dementia and according to the most recent estimation it affects nearly 27 million people in the world. The onset of the disease is generally insidious. It is becoming increasingly evident that the underlying pathophysiological mechanisms are active long before the appearance of the clinical symptoms of the disease. In the current context, it is important to develop strategies to delay the onset of cognitive decline. Delaying the onset by 5 years would reduce the prevalence by half at term, and a delay of 10 years would reduce it by three-quarters. The effectiveness of currently suggested preventive approaches remains to be confirmed, but certain strategies could be applied straight away to at-risk subjects. We propose that a health-promoting memory consultation should be set up for elderly persons who have attended a specialized memory consultation and in whom the diagnosis of dementia and of AD in particular, has not been established by standardized tools. Through this consultation, they would be offered full multidimensional investigation of all aspects of their health status, follow-up could be organized, general practitioners in private practice could be made more conscious of this population and the elderly could be made more aware of the risk factors to which they are exposed. The development of an information policy for the elderly would meet a present need. In our reflection, we must take into account the question of how to give this preventive consultation its due place in the healthcare pathway of the elderly person in order to ensure coordinated follow-up with all the other health professionals involved. The principle of the health-promoting memory consultation is undergoing validation in a large French multicentre preventive trial in 1200 frail elderly persons aged 70 years followed for three years, the Multidomain Alzheimer Preventive Trial (MAPT).

Patients with a blunted fall in nocturnal BP (known as non-dippers) have a high risk of micro- and macrovascular complications, particularly if they have hypertension, but also in normotensive patients with diabetes. A blunted fall in nocturnal BP reflects the high level of CV risk in these patients. ABPM data indicating an altered circadian BP rhythm reverse circadian BP profile should alert the physician to the potential risk of complications and should lead to efforts to treat hypertension effectively, especially at night, and to check for sleep apnoea syndrome, particularly in cases of resistant hypertension, or autonomic neuropathy (postural hypotension), a well known risk factor for cardiovascular (CV) events. Patients should be carefully screened for nephropathy. However, the definitions of "non-dipper" vary widely. Suitable treatments are poorly defined, but angiotensin-converting enzyme inhibitors (ACEi), diuretics, salt restriction and the maintenance of continuous positive airway pressure (CPAP) can be used as non-specific treatments. The efficacy of taking blood pressure-lowering drugs at bedtime rather than in the morning is still debated but deserves attention. In the diabetic population, brachial pulse pressure (PP) is an independent predictor of cardiovascular mortality, but not of all-cause mortality. It is also associated with complications of both type 2 and type 1 diabetes, this effect being stronger for nocturnal than for diurnal PP, and is strongly predictive of coronary heart disease in patients with type 2 diabetes. The stronger association between PP and age in diabetic than in non-diabetic populations suggests that diabetes accelerates vascular ageing. In patients with incipient nephropathy or overt renal failure, PP increases CV risk. However, misinterpretation could be related to confusion between brachial PP and central PP. The therapeutic implications of PP measurement remain poorly documented in diabetes.

Hypertensive patients with altered circadian blood pressure (BP) profile experience greater repercussion of hypertension on target organs and a higher risk of cardiovascular events, compared with those with physiological variations in BP. It has been demonstrated in animal models, that circadian variations in BP depend on several regulatory systems, in particular the nitric oxide-cGMP pathway. eNOS298 Glu/Asp polymorphism is a functional variant and may alter the amount of NO generated or eNOS activity. The objective of the present study was to find out whether eNOS298 gene polymorphism affects circadian BP regulation in 110 healthy subjects and 155 never-treated hypertensive patients recruited at Hypertension Units in Grenoble, Toulouse and Lille (France).

The TROPHY study was designed to show the feasibility of pharmacological prevention of hypertension with respect to the group of patients with "prehypertension" as defined by the JNC VII recommendations. This clinical trial compared candesartan 16 mg/day with placebo and the result at 4 years was a reduction in the relative risk of developing hypertension of 15.6%. The antihypertensive drug delayed the onset of hypertension in a mainly overweight masculine population. Staessen, Zhu and O'Brien's groups suggest measuring an index of arterial rigidity obtained from ambulatory blood pressure monitoring: the ambulatory arterial stiffness index (AASI). This is calculated as [1- slope of systolic/diastolic pressure]. The reference values for AASI vary with age from 0.50 to 0.70. The CAFE study, a spin-off of the ASCOT trial, showed that the central blood pressure decreased more than the peripheral blood pressure with the association amlodipine-perindopril as compared with atenolol and a thiazide diuretic. The capacity of an antihypertensive drug or an association of antihypertensives to decrease the central blood pressure could be a pertinent factor of evaluation to be taken into account in the interpretation of clinical trials. The study of the Italian cohort PAMELA showed a progressive increase in cardiovascular and global mortality with respect to the findings of increased blood pressure by one, two or three methods of measurement (at the office, at home, ambulatory) compared with patients declared normotensive by the same methods. This registry confirmed the implication of masked hypertension on cardiovascular prognosis and also showed that "white coat" hypertension was not completely benign. The "3 cities" study is a French epidemiological study of persons over 65 years of age. The control of the blood pressure of the treated elderly hypertensives was 57% in men and 70% in women when the cut-off was 160/95 mmHg and 31% for all patients in a cut-off level of 140/90 mmHg. Lafontan et al. are studying the mobilisation of fat induced by exercise, resistant to betablockers therapy and attributed to natriuretic peptides. This metabolic pathway could be of relevance in the metabolic syndrome and in cardiac failure. Renin inhibitors, such as aliskiren, are being developed. The outlook is the possible use of these drugs with ACE inhibitors or angiotensin II inhibitors, taking into account the risk/benefit ratio.

Self blood pressure measurements (home BP) and/or ambulatory BP measurements are recommended in mild to moderate hypertension (140/90 - 179/109 mmHg) in order to confirm sustained hypertension and identify white coat and masked hypertension. The evaluation of target organ damages (TOD) has to be integrated in cardiovascular risk estimate and taken into account in the management of hypertensive patients. Beside echocardiography, there is a place for the screening of microalbuminuria in non diabetic hypertensive patients, but these investigations should not be performed systematically. Arterial stiffness evaluation and carotid intima-media thickness quantification are not yet recommended. Cardiovascular risk (CV risk) estimate plays a pivotal role in the therapeutic decision and strategy. The cardiovascular risk grade is based on [1] the list of cardiovascular risk factors (same list AFSSAPS recommendations on dyslipidemia), [2] the presence or absence of TOD and [3] cardiovascular complications: "low", "medium", and "high" CV risk. Lifestyle modifications are recommended in all hypertensive patients. Five antihypertensive drugs are recommended for first line therapy: beta-blockers, thiazide diuretics, ACEIs, ARA II and CCBs (and fixed low dose combinations with AFSSAPS agreement for first line). In order to initiate the treatment, Evidence-based therapy (according to clinical trials conducted in different clinical situations), certain comorbid conditions (compelling indications), efficacy and side-effects in a previous experience, and the cost are the determinants of the first choice. Most hypertensive patients require more than one agent to achieve target blood pressure and for second line therapy the recommended combinations are: betablockers-diuretics, ACEIs-diuretics, ARAII-diuretics, betablockers-CCBs (DHP), ACEIs-CCBs, ARA II-CCBs and CCBs-diuretics. The delay to establish a combination therapy depend on CV risk. The BP goals are those recommended by ESH-ESC 2003: BP<140/90 mmHg in all, BP<130/80 mmHg in diabetic patients and in patients with chronic renal failure. Beside lowering BP, the reduction in proteinuria <500 mg/24 h is a new goal in these high risk patients. These guidelines provide a tool for every day practice and applicability should be evaluated.

European medical students should have acquired adequate prescribing competencies before graduation, but it is not known whether this is the case. In this international multicenter study, we evaluated the essential knowledge, skills, and attitudes in clinical pharmacology and therapeutics (CPT) of final-year medical students across Europe. In a cross-sectional design, 26 medical schools from 17 European countries were asked to administer a standardized assessment and questionnaire to 50 final-year students. Although there were differences between schools, our results show an overall lack of essential prescribing competencies among final-year students in Europe. Students had a poor knowledge of drug interactions and contraindications, and chose inappropriate therapies for common diseases or made prescribing errors. Our results suggest that undergraduate teaching in CPT is inadequate in many European schools, leading to incompetent prescribers and potentially unsafe patient care. A European core curriculum with clear learning outcomes and assessments should be urgently developed.

In 2005, new data on the prognostic value of blood pressure measurement in the home and by ambulatory recordings were published from the Italian (PAMELA) and Japanese (OHASAMA) registers. The ambulatory BP has a greater prognostic value than that measured in the physician's office in hypertensive patients whereas the difference in prognostic value is less in normotensive patients. The prevalence of masked hypertension is estimated at 15 to 26% with reference to the diastolic and systolic BP. The cardiovascular risk is significantly higher in patients with permanent or masked hypertension compared with normotensive subjects and "white coat" hypertensive patients. The ASCOT trial showed that in primary prevention of hypotensive patients with more than 3 associated cardiovascular risk factors, a strategy based on amlodipine secondarily associated with a diuretic, provided better control of the blood pressure than that of a betablocker secondarily associated with a diuretic: the therapeutic trial was negative with respect to the primary criterion including fatal coronary events and non-fatal myocardial infarction but the trial was stopped prematurely because of a significant reduction in cardiovascular and global mortality in the amlodipine-perindopril arm compared with the atenolol-thiazide arm. The metaregression of Verdecchia confirmed that the reduction of the BP remains the essential beneficial factor of antihypertensive therapy, but suggested that; in addition to the reduction of the blood pressure, ACE inhibitors provided better protection against coronary disease than calcium antagonists whereas the calcium antagonists were superior to ACE inhibitors for prevention of stroke. The endothelium is confirmed as a potential therapeutic target. Endothelial dysfunction has been demonstrated in resistance and conduction vessels. The study of antihypertensive therapy on endothelial vasodilation is a new pharmacological approach which may help differentiate the benefits of different classes. New data has documented the relations between inflammation, the vessel and hypertension, and different cytokines hs-CRP, ICAM1, IL6, TNF alpha and MCP-1 may be implicated. The new HAS 2005 recommendations for the management of adult hypertensive patients have been published recently; they are an updated reference for the optimisation of treatment in everyday clinical practice in France. The value of auto-measurement and ambulatory BP recording, the necessary estimation of global cardiovascular risk, the use of the 5 classes of antihypertensive drugs having shown a reduction in cardiovascular morbid-mortality, constitute the key points of these recommendations. Finally, data is now available concerning the incidence of hypertension in France in a working population (IPHAF study) and is estimated at 3% in men and 1.34% in women.

PURPOSE: To describe pharmacists' interventions made at patients hospital discharge from Department of Hypertension. METHODS: This is a single-center and prospective study over an 8-week period. At hospital discharge, the pharmacist compared pre-admission and inpatient medications with discharge orders and written instructions. Pharmacists' interventions were then classified in 4 categories. All variances and discrepancies were discussed with the prescribing physician when possible. RESULTS: Over the 8-week period, 154 cases were analyzed. Pharmacists' interventions at discharge underwent 48 times on 21% of the patients (n=33) but none was clinically relevant. Among these 48 cases, 40% (n=19) were rated as "inappropriate administration", 27% (n=13) were classified as "incomplete prescription", 19% (n=9) were "variances" and 4% (n=2) were due to "omission prescription". In 10% of the cases (n=5), discrepancies appeared without any possible further analysis as no discussion with the prescriber occurred. CONCLUSION: One fifth of all patients analyzed was the subject of a pharmacists' intervention. The complementary action of the pharmacist improves the consistency of the prescriptions and strengthens patient safety.

OBJECTIVE: To study the prevalence of different causes of hypertension in young adults referred to a hypertension center in the south west of France. METHODS: We conducted a retrospective overview of patients younger than 40years old hospitalized consecutively in the Hypertension department of Toulouse University Hospital between 2012 and 2014. Clinical data about gender, age, anthropomorphic parameters and blood pressure measurement by 24h Ambulatory Blood Pressure Monitoring (ABPM) were recorded. Biological data concerned dosages of kalemia, renin and aldosterone in the supine or after 15min of seating. Recorded radiological examinations were renal artery ultrasound and abdominal CT scan. RESULTS: One hundred and forty-eight detailed medical records were analyzed, 69 women and 79 men. Among the 69 women, the causes of secondary hypertension were primary aldosteronism (n=7), fibromuscular dysplasia (n=5) and renal disease (n=4). Oral contraceptives were involved in 13 women. In addition, essential hypertension concerned 40 women (58%). Among the 79 men, the causes of secondary hypertension were primary aldosteronism (n=10), fibromuscular dysplasia (n=3), left main renal artery entrapment by a diaphragmatic crura (n=2), renal disease (n=1), pheochromocytoma (n=3) and coarctation of the aorta (n=2). In addition, essential hypertension concerned 58 men (73%). CONCLUSIONS: In our population, the prevalence of secondary hypertension is close to 33% (42% of females and 27% of males), with the following main causes: primary aldosteronism for 11.5%; fibromuscular dysplasia for 5.4%. Oral contraceptives were involved in the hypertension of 19% of the females.

To improve the management of resistant hypertension, the French Society of Hypertension, an affiliate of the French Society of Cardiology, has published a set of eleven recommendations. The primary objective is to provide the most up-to-date information based on the strongest scientific rationale and that is easily applicable to daily clinical practice. Resistant hypertension is defined as uncontrolled blood pressure on office measurements and confirmed by out-of-office measurements despite a therapeutic strategy comprising appropriate lifestyle and dietary measures and the concurrent use of three antihypertensive agents including a thiazide diuretic, a renin-angiotensin system blocker (ARB or ACEI) and a calcium channel blocker, for at least 4 weeks, at optimal doses. Treatment compliance must be closely monitored, as must factors that are likely to affect treatment resistance (excessive dietary salt intake, alcohol, depression, drug interactions and vasopressor drugs). If the diagnosis of resistant hypertension is confirmed, the patient should be referred to a hypertension specialist to screen for potential target organ damage and secondary causes of hypertension. The recommended treatment regimen is a combination therapy comprising four treatment classes, including spironolactone (12.5-25 mg per day). In the event of a contraindication or a non-response to spironolactone, or if adverse effects occur, a ß-blocker, an α-blocker, or a centrally acting antihypertensive drug should be prescribed. Because renal denervation is still undergoing assessment for the treatment of hypertension, this technique should only be prescribed by a specialist hypertension clinic.

OBJECTIVE: To evaluate systolic blood pressure (SBP) control in hypertensive patients with a stable coronary heart disease (CHD) in general practice in France. METHODS: A survey was conducted in a sample of 206 general practitionners (GP) representative of the French medical population, in 2003 [LHYCORNE survey]. Each GP had to include 3 hypertensive patients, >18 years old, BP > or = 140/90 mmHg and/or treated for hypertension, and with evidence of CHD documented by myocardial infarction (MI) or angina pectoris (AP) [diagnosis previously established by a cardiologist]. Three office BP measurements were performed, the last two recorded. BP levels were considered as controlled by treatement if they were < 140/90 mmHg. RESULTS: 595 patients were included, 75% men mean age 66 years, 25% women mean age 73 years. All patients had a CHD: MI 46%, AP 54%; 533 (90%) had more than 2 cardiovascular risk factors: hyperlipidemia (411; 69%), smokers (375; 63%), diabetes (158; 27%). Mean BP was 140.7 +/- 14/80.8 +/- 9.7 mmHg; 553 (93%) of these hypertensive patients were treated, and 239 (40%) were considered as having a controlled SBP at the treshold of 140 mmHg: 47% in patients with previous MI and 38% with AP (p < 0.001). Diastolic BP (DBP) was <90 mmHg in 480 (81%) and pulse pressure was >65 mmHg in 202 (34%); 313 (53%) patients received a combination of three drugs or more; 354 (60%) had a beta-blocker, 260 (44%) a calcium channel blocker, 237 (40%) an ACE inhibitor, 287 (48%) other antihypertensive drugs (246 diuretics, 41%); 502 (84%) received antiplatelet therapy, 403 (68%) statins. CONCLUSION: This survey shows that systolic BP is not at goal in 6/10 hypertensive patients with stable CHD suggesting there is a place for a more effective combination therapy according to evidence-based medicine.

AIMS: To study the influence of postural changes on aldosterone to renin ratio (ARR) in patients with suspected secondary hypertension and to evaluate the sensitivity and specificity of the recommended seated ARR compared to supine and upright ARR for primary aldosteronism screening. METHODS: Fifty-three hypertensive patients were prospectively hospitalized for secondary hypertension exploration (age: 51 ± 12, 66% males). After withdrawal of drugs interfering with renin angiotensin system, plasma aldosterone and direct renin concentration were measured in the morning, at bed after an overnight supine position, then out of bed after 1 hour of upright position and finally 2 hours later after 15 minutes of seating. Minimal renin value was set at 5 µUI/mL. RESULTS: Referring to ARR cut-off of 23 pg/µUI, the sensitivity of seated ARR was 57.1% and specificity was 92.3%. The negative and positive predictive values were 95.1% and 45.2% respectively. Compared to these results, a cut-off of 19 improved sensitivity to 85.7% with a specificity of 89.7%. Negative and positive predictive values were 98.3% and 41.1% respectively. Seated ARR mean value was lower than supine and upright ARR mean values, due to an overall increase in renin at seating compared to the supine position by factor 1.9 while aldosterone just slightly increased by factor 1.2. Seated ARR correlated to supine and upright ARR: correlation coefficients (r) 0.90 and 0.93 respectively (P<0.001). CONCLUSIONS: Current recommended measurement of ARR in the seating position is fairly correlated to supine and upright ARR. A suggested cut-off value of 19 instead of 23 pg/µUI increased the discriminating power of this test.

PURPOSE: To synthesize pharmacists' interventions made in the department of internal medicine and hypertension of university hospital of Toulouse and assess the impact on medication orders. METHODS: This is a single-center, prospective study using pharmacists' interventions recorded between September 2013 and March 2014 on the Act-IP(©) website of the French Society of Clinical Pharmacy. The clinical pharmacist is present everyday in the unit to establish the medication reconciliation of new patients (the process of comparing a patient's medication orders to all of the medications that the patient has been taking), and analysis of medication orders. When a risk of iatrogenic drug is identified, a therapeutic change is proposed to the prescriber. RESULTS: A total of 2491 medication orders were analyzed for 7 months, leading to 39 pharmacists' interventions (1.6 pharmacists' interventions per 100 medication orders). The most commonly identified drug-related problems were improper administration (33%, n=13), not prescribed drug (21%, n=8), non-conformity to guidelines (18%, n=7), supratherapeutic dose (15%, n=6), and 13% (n=5) targeted prescribed treatment not administered, underdosing, incorrect administration or drug interaction. The most relevant molecules were atorvastatin (10%), bromazepam (8%) and levothyroxine (8%) and only 2 interventions targeted antihypertensive drugs. The rate of physicians' acceptance was 92%. CONCLUSION: Pharmacists' interventions mainly concern the co-prescriptions of antihypertensive drugs and very few antihypertensive drugs. The clinical pharmacist contributes to preventing iatrogenic in patients with hypertension with a very good acceptance by the clinician.

The aim of this study was to find out whether the dysfunction of aldosterone pathway, previously proposed as a marker of secretory adrenal carcinoma, is also found in nonsecretory adrenal carcinomas, which pose even more difficult diagnostic problems even for patients with hypertension accompanied or not by hypokalemia. The exploration consisted of using the same method (RIA preceded by a chromatographic step) to determine the plasma levels of the following steroids in the mineral corticosteroid pathway: deoxycorticosterone (DOC), 18-hydroxydeoxycorticosterone (18-OHDOC), corticosterone (B), 18 hydroxycorticosterone (18 OH B), and aldosterone. The subjects included 16 adults, each presenting with an endocrinologically asymptomatic adrenal mass associated for some patients with hypokalemia and hypertension (8 with adrenal carcinoma, 2 with adrenal metastasis from other forms of cancer, and 6 adenomas). These results show that even in nonsecretory adrenal carcinoma, there is a dysfunction of the aldosterone pathway, which can be evaluated from the ratio between aldosterone and the substrate of 11 beta hydroxylase (DOC) and its derivative (18-OH DOC). This study suggests that exploration of mineralocorticosteroid pathway can be used as a hormonal marker of adrenal carcinoma for both secretory and non-secretory malignant masses.
