1 Optimal Dose of Irbesartan for Renoprotection in Type 2 Diabetic Patients With Persistent Microalbuminuria

Aim: To evaluate the renoprotective effect as reflected by short-term changes in albuminuria of ultra high doses of irbesartan in Type 2 diabetic patients with microalbuminuria Design: A double-masked randomized cross-over trial including 60 hypertensive Type 2 diabetic patients with microalbuminuria on ongoing antihypertensive medication. At inclusion, previous antihypertensive treatment will be discontinued and replaced with bendroflumethiazide 5 mg o.d. for the entire study. Following two months wash-out (baseline), patients will be treated randomly with irbesartan 300, 600 and 900 mg o.d., each dose for two months. End-points evaluated at the end of each study period include urinary albumin excretion rate (UAE, mean of three 24-hrs collections), 24-hrs blood pressure (ABP); and GFR (51Cr-EDTA).

Initially we will evaluate the influence of the ACE/ID- , Angiotensin II type I receptor (A1166C) - and the angiotensinogen (M235T) polymorphisms. --- A1166C ---

2 A Randomized, Open Label, Cross-over Comparative Study of Irbesartan/Hydrochlorothiazide and Irbesartan in the Treatment of Mild to Moderate Hypertension

Primary: 1. To compare the change in forearm vascular resistance following a 12-week regimen of irbesartan/hydrochlorothiazide versus irbesartan 2. To assess changes of serum proinflammatory cytokine, markers of cardiovascular risks, oxidative stress and circulating adhesion molecule including thiobarbiturate acid reactive substances (TBARS), C-reactive protein (CRP), interleukin 6 (IL-6), and vascular cell adhesion molecule 1 (VCAM-1). Secondary: 1. To compare the reduction in office blood pressure following a 12-week regimen of irbesartan/hydrochlorothiazide versus irbesartan 2. To compare the response rate (defined as office Systolic blood pressure(SBP)/diastolic blood pressure (DBP) reduce more than 10mmHg from baseline), and BP controlled rate (defined as SBP<140 mmHg and /or DBP<90 mmHg) 3. To ascertain the safety and tolerability of irbesartan / hydrochlorothiazide versus irbesartan when administered once daily 4. To determine whether angiotensin II type 1 (AT-1) receptor gene polymorphisms (including A1166C gene with about 4% of the minor allele frequency in Chinese population and other single nucleotide polymorphisms with a higher frequency of about 10% of minor allele) is related to reduction of BP

3 Observational Study of the Polymorphisms of the Renin-angiotensin-aldosterone System and Their Relation to Resistant Systemic Arterial Hypertension and Adverse Cardiovascular Events

Renin-angiotensin-aldosterone system (RAAS) polymorphisms influence 24h arterial pressure fluctuation. Resistant systemic arterial hypertension (RSAH) has an increased risk of end organ damage and unfavourable prognosis, whereas pseudo-RSAH usually respond favourably to drug therapy. To prospectively investigate, in subjects with RSAH in a tropical South American city: 1) Adverse cardiovascular events defined as fatal and non-fatal stroke or acute myocardial infarction (AMI); and 2) the association of RAAS polymorphisms and adverse cardiovascular events in this population. Study population: 212 hypertensives recruited from primary care assistance (time since first diagnosis of hypertension: 16.5±8.1 years) and without appropriate pressure control, between 2001 and 2006, corresponding to 0.48% of all hypertensives under care (18 new cases/year), 57±10 years old, 66% females. Under drug treatment schedule: three or more drugs including a diuretic. Ninety two randomly selected hypertensives basis had renin-angiotensin-aldosterone system genetic profile determined. Genetic assessment was carried out using a polymerase chain reaction assay amplification technique. The following single nucleotide polymorphisms were analyzed: renin (G1051A), angiotensinogen (M235T), angiotensin converting enzyme-ACE (I/D), angiotensin II type 1 receptor (A1166C), aldosterone synthase (C344T) and mineralocorticoid receptor (G3514C).

Death was considered to be related to the event if occurring up to 30 days after the acute event. Assessment twice an year by active and direct contact to patients or relatives and review of medical records.

Evidence of clinically definite acute myocardial infarction (prolonged > 20min chest pain, not relieved by sublingual nitrate, ST-T segment deviation on 12-lead surface ECG, elevation of plasma troponin >0.2 ng/dL 6h following chest pain episode). Death was considered to be related to the event if occurring up to 30 days after the acute event.
