The repercussion of stopping reimbursement of olmésartan on antihypertensive drugs prescription and blood pressure control of treated hypertensive patients in France.

OBJECTIVE: Since January 2017, olmesartan-based treatments are no longer reimbursed by French health insurance. Health authorities have recommended switch to one of the "many effective, better tolerated and reimbursed alternatives". The objective of this study was to evaluate the consequences on the prescription of antihypertensive drugs in France and to evaluate the blood pressure control of treated hypertensive patients after the switch from olmesartan to another Angiotensin receptor blocker (ARB). METHODS: To evaluate antihypertensive prescriptions, the French League Against Hypertension Survey (FLAHS) was conducted in 2007, 2012 and 2017 by self-questionnaire sent by mail to a representative panel of the population living in metropolitan France aged 35 years and over. Antihypertensive treatments were grouped by pharmacological class. To evaluate blood pressure control in hypertensive patients treated with olmesartan alone or in combination, 3 home blood pressure monitoring (HBPM) were performed. The first and the second were performed without modification of the dose of olmesartan. The third was performed 1 month after the switch to another ARB. RESULTS: Antihypertensive prescriptions changed between 2007 and 2017. Beta-blockers decreased between 2007 and 2012 and then increased slightly. Between 2012 and 2017, ARB and diuretics decreased and ACE inhibitors (ACE-I) and calcium antagonist (CA) drugs increased. Blood pressure control was assessed in 82 hypertensive patients aged 63±11 years treated with olmesartan. The difference in SBP/DBP between the first 2 self-measurements was -0.96/-0.83mmHg. After therapy switch, the 3rd self-measurement showed an increase in SBP/DBP of 3.4/1.2mmHg. In the subgroup of olmesartan-treated controlled hypertensive patients, the switch to another ARB lead to uncontrolled hypertension for 20% of patients with a 12.1mmHg increase in SBP. CONCLUSION: With the halt of reimbursement of olmesartan, there was a decrease in the prescription of ARB in France. When olmersartan was replaced by another ARB, a worse blood pressure control was observed in treated hypertensive patients. The cessation of the reimbursement of olmesartan has had consequences on the treatment of hypertension in France.

Organization of care for multiple sclerosis in France.

Multiple sclerosis (MS) is a disease with a number of aspects involving cooperation among many caregivers. In France, the organization of care for patients with MS has changed over the past 10 years with the development of specific structures, such as regional networks and expert centers. Their aims are to help improve MS patient care and quality of life. Multiple domains are involved, ranging from MS diagnosis to treatment, and including rehabilitation and the psychological and social impact of the disease. Thus, a personalized plan of care service is set up for each MS patient under the guidance of MS healthcare professionals.

[Ischemic stroke related to spontaneous]. / Accident vasculaire cérébral ischémique en rapport avec hématome coronaire spontané.

Cardiovascular disease in women is a particularly complex pathology especially in the youngest population. The clinical presentation of acute coronary syndromes is sometimes misleading and does not necessarily point to the potential presence of cardiac disease given the frequent absence of cardiovascular risks. Such complexity results in delayed diagnosis, which worsens the outcome of myocardial infarction and generates complications related to the absence of coronary revascularization. We report the case of a patient who suffered an (undiagnosed) apical myocardial infarction that went undetected and was complicated by a voluminous intraventricular thrombus with embolus migration in the cerebral circulation resulting in an ischemic accident. The combination of these two pathologies make their therapeutic management particularly difficult. As widely reported in the literature, the outcome of myocardial infarction in women is poorer than in their male counterparts for a number of reasons. We can assume that in the youngest patients, another physiopathological mechanism is often involved, namely, the occurrence of hematoma and spontaneous coronary dissection. Diagnosis is often difficult even with coronary angiography diagnosis. As shown in the case reported here, initial examination results, if not thoroughly analyzed, may be erroneously interpreted as normal. It is also likely that the presence of hematoma or coronary wall dissection without any plaque rupture may negatively influence the outcome owing to the implementation of inappropriate treatments. In conclusion, in patients presenting with an ischemic cerebral accident, meticulous cardiac examination must be performed even in young women with no cardiovascular risk factors given that the occurrence of hematoma or coronary dissection may contribute to the formation of mural thrombi in the setting of myocardial infarction. Cardiac MRI seems to be particularly effective in the diagnosis of myocardial infarction complicated by the presence of intracavitary thrombi.

Pretransplant sensitization against angiotensin II type 1 receptor is a risk factor for acute rejection and graft loss.

The angiotensin II type 1 receptor (AT1R) is an emerging target of functional non-HLA antibodies (Ab). We examined the potential of determining the degree of presensitization against AT1R as a risk factor for graft survival and acute rejection (AR). The study included 599 kidney recipients between 1998 and 2007. Serum samples were analyzed in a blinded fashion for anti-AT1R antibodies (AT1R-Abs) using a quantitative solid-phase assay. A threshold of AT1R-Ab levels was statistically determined at 10 U based on the time to graft failure. An extended Cox model determined risk factors for occurrence of graft failure and a first AR episode. AT1R-Abs >10 U were detected in 283 patients (47.2%) before transplantation. Patients who had a level of AT1R-Abs >10 U had a 2.6-fold higher risk of graft failure from 3 years posttransplantation onwards (p = 0.0005) and a 1.9-fold higher risk of experiencing an AR episode within the first 4 months of transplantation (p = 0.0393). Antibody-mediated rejection (AMR) accounted for 1/3 of AR, whereby 71.4% of them were associated with >10 U of pretransplant AT1R-Abs. Pretransplant anti-AT1R-Abs are an independent risk factor for long-term graft loss in association with a higher risk of early AR episodes.
