Impact of clinical pharmacy on the psychotropic drugs prescription in neurological rehabilitation: A retrospective study

IntroductionPsychotropic drugs are frequently prescribed in neuro-rehabilitation. In our institution, they account for 18% of prescriptions. For several years, clinical pharmacy activities were developed in collaboration with physicians and psychiatrists. The aim of this study is to evaluate the impact of this approach by the retrospective measure of psychotropic drugs consumption over 4 years, and link them to the evolution of hospital stays recorded through the PMSI (Programme de médicalisation des systèmes d’information, France).MethodsThe study took place over the period 2010–2013. It included three steps: 1/Monitoring of psychotropic drugs consumption (antipsychotics, anxiolytics, hypnotics and antidepressants) of 9 units (225 beds), by value and treatment days calculated from the daily average dosage (THERIAQUE); 2/Identification of hospitalised patients with at least one diagnosis code of either depression, anxiety, insomnia, and/or psychotic disorders; 3/Analysis of patient data with regard to drug consumption.ResultsFrom 2010 to 2013, the cost of psychotropic drugs was reduced by 24%, from 17,617 to 13,366 euros. The number of treatment days decreased by 30% from 84,765 to 59,466 days. The most significant decline was for hypnotic drugs (–62%) (28,110 to 10,623 days), and anxiolytic drugs (–37%) (28,958 to 18,343 days). The usage of antidepressant drugs increased by 21% (19,996 to 24,154 days), while the usage of antipsychotic drugs was stable (6346 days in 2013). During the same period, the overall number of patients with psychological diagnosis code hospital stays increased by 146% (213 to 523). It can be further detailed as follows: +380% for patients with an anxiety disorder (60 to 287), +71% for patients with depressive symptoms (78 to 133). Stays of patients with psychotic disorders remained stable.DiscussionThis study illustrates that a clinical pharmacy action targeted on psychotropic drugs prescriptions in collaboration with physicians and psychiatrists has reduced their consumption in neuro-rehabilitation. This decrease concerns mainly anxiolytic drugs and hypnotic drugs, despite the rise in number of hospital stays of patients with anxiety disorders. These results follow the recent recommendations of the ANSM (Agence nationale de sécurité du médicament, France)

Assessment of coronary atherosclerosis by IVUS and IVUS-based imaging modalities: progression and regression studies, tissue composition and beyond

Cardiovascular disease remains the leading cause of mortality, morbidity and disability in the developed world, predominantly affecting the adult population. In the early 1990s coronary heart disease (CHD) was established as affecting one in two men and one in three women by the age of forty. Despite the dramatic progress in the field of cardiovascular medicine in terms of diagnosis and treatment of heart disease, modest improvements have only been achieved when the reduction of cardiovascular mortality and morbidity indices are assessed. To better understand coronary atherosclerosis, new imaging modalities have been introduced. These novel imaging modalities have been used in two ways: (1) for the characterization of plaque types; (2) for the assessment of the progression and regression of tissue types. These two aspects will be discussed in this review

Prognostic value of fractional flow reserve: Linking physiologic severity to clinical outcomes

BACKGROUND: Fractional flow reserve (FFR) has become an established tool for guiding treatment, but its graded relationship to clinical outcomes as modulated by medical therapy versus revascularization remains unclear.OBJECTIVES: The study hypothesized that FFR displays a continuous relationship between its numeric value and prognosis, such that lower FFR values confer a higher risk and therefore receive larger absolute benefits from revascularization.METHODS: Meta-analysis of study- and patient-level data investigated prognosis after FFR measurement. An interaction term between FFR and revascularization status allowed for an outcomes-based threshold.RESULTS: A total of 9,173 (study-level) and 6,961 (patient-level) lesions were included with a median follow-up of 16 and 14 months, respectively. Clinical events increased as FFR decreased, and revascularization showed larger net benefit for lower baseline FFR values. Outcomes-derived FFR thresholds generally occurred around the range 0.75 to 0.80, although limited due to confounding by indication. FFR measured immediately after stenting also showed an inverse relationship with prognosis (hazard ratio: 0.86, 95% confidence interval: 0.80 to 0.93; p < 0.001). An FFR-assisted strategy led to revascularization roughly half as often as an anatomy-based strategy, but with 20% fewer adverse events and 10% better angina relief.CONCLUSIONS: FFR demonstrates a continuous and independent relationship with subsequent outcomes, modulated by medical therapy versus revascularization. Lesions with lower FFR values receive larger absolute benefits from revascularization. Measurement of FFR immediately after stenting also shows an inverse gradient of risk, likely from residual diffuse disease. An FFR-guided revascularization strategy significantly reduces events and increases freedom from angina with fewer procedures than an anatomy-based strategy

Association of the PHACTR1/EDN1 genetic locus with spontaneous coronary artery dissection

Background: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndromes (ACS) afflicting predominantly younger to middle-aged women. Observational studies have reported a high prevalence of extracoronary vascular anomalies, especially fibromuscular dysplasia (FMD) and a low prevalence of coincidental cases of atherosclerosis. PHACTR1/EDN1 is a genetic risk locus for several vascular diseases, including FMD and coronary artery disease, with the putative causal noncoding variant at the rs9349379 locus acting as a potential enhancer for the endothelin-1 (EDN1) gene. Objectives: This study sought to test the association between the rs9349379 genotype and SCAD. Methods: Results from case control studies from France, United Kingdom, United States, and Australia were analyzed to test the association with SCAD risk, including age at first event, pregnancy-associated SCAD (P-SCAD), and recurrent SCAD. Results: The previously reported risk allele for FMD (rs9349379-A) was associated with a higher risk of SCAD in all studies. In a meta-analysis of 1,055 SCAD patients and 7,190 controls, the odds ratio (OR) was 1.67 (95% confidence interval [CI]: 1.50 to 1.86) per copy of rs9349379-A. In a subset of 491 SCAD patients, the OR estimate was found to be higher for the association with SCAD in patients without FMD (OR: 1.89; 95% CI: 1.53 to 2.33) than in SCAD cases with FMD (OR: 1.60; 95% CI: 1.28 to 1.99). There was no effect of genotype on age at first event, P-SCAD, or recurrence. Conclusions: The first genetic risk factor for SCAD was identified in the largest study conducted to date for this condition. This genetic link may contribute to the clinical overlap between SCAD and FMD

Collaborative work in a complex case of Fontan for treating intra-atrial reentrant tachycardia and severe aortic stenosis: a case report

International audienceBACKGROUND: Intra-atrial reentrant tachycardia (IART) is a frequent arrhythmia in patients with Fontan circulation. Although its supraventricular origin, such arrhythmia can be poorly tolerated as it leads to haemodynamic impairment. Concomitant assessment of pressure/volume overload of cardiac chambers due to valvular disease or residual shunts is necessary. CASE SUMMARY: We report the case of a 33-year-old male with Fontan extracardiac conduit, suffering from IART with initial poor haemodynamic tolerance. He had a medical history of pulmonary atresia with intact ventricular septum and Type 0 bicuspid aortic valve, with a total of four cardiac surgeries. Echocardiography demonstrated a severe impairment of the univentricular ejection fraction and a critical aortic stenosis. Given the limited medical treatment options of the arrhythmia and the risks of another heart surgery, both IART ablation and transcatheter aortic valve replacement (TAVR) were performed during the same procedure. The IART critical isthmus located in the antero-lateral region of the extracardiac conduit was effectively treated with radiofrequency. Rapid pacing during TAVR was provided by a catheter placed in the unique ventricle via a transconduit puncture. The aortic valve was deployed with minimal para-valvular regurgitation and a satisfactory transvalvular gradient. At follow-up, the univentricular ejection fraction normalized and no arrhythmic episode was recorded in absence of anti-arrhythmic drugs. DISCUSSION: This case highlights the need of a collaborative approach for treating complex cases of adult congenital heart disease, suffering from both electrophysiological and haemodynamic disorders. This combination offered an elegant and safest solution for treating concomitantly a life-threatening arrhythmia and an aortic stenosis

Cyclosporine before PCI in Patients with Acute Myocardial Infarction

BACKGROUND: Experimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling. METHODS: In a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute anterior ST-segment elevation myocardial infarction (STEMI) who were undergoing percutaneous coronary intervention (PCI) within 12 hours after symptom onset and who had complete occlusion of the culprit coronary artery to receive a bolus injection of cyclosporine (administered intravenously at a dose of 2.5 mg per kilogram of body weight) or matching placebo before coronary recanalization. The primary outcome was a composite of death from any cause, worsening of heart failure during the initial hospitalization, rehospitalization for heart failure, or adverse left ventricular remodeling at 1 year. Adverse left ventricular remodeling was defined as an increase of 15% or more in the left ventricular end-diastolic volume. RESULTS: A total of 395 patients in the cyclosporine group and 396 in the placebo group received the assigned study drug and had data that could be evaluated for the primary outcome at 1 year. The rate of the primary outcome was 59.0% in the cyclosporine group and 58.1% in the control group (odds ratio, 1.04; 95% confidence interval [CI], 0.78 to 1.39; P=0.77). Cyclosporine did not reduce the incidence of the separate clinical components of the primary outcome or other events, including recurrent infarction, unstable angina, and stroke. No significant difference in the safety profile was observed between the two treatment groups. CONCLUSIONS: In patients with anterior STEMI who had been referred for primary PCI, intravenous cyclosporine did not result in better clinical outcomes than those with placebo and did not prevent adverse left ventricular remodeling at 1 year.

Concomitant drugs with low risks of drug-drug interactions for use in oncology clinical trials

International audienceBACKGROUND: Drug-drug interactions (DDIs) may occur with investigational drugs and affect patient safety, trial outcomes, and drug development. A list of preferred drugs with minimal risks of DDIs for treatment of symptoms or comorbidities frequently encountered by cancer patients would be helpful. METHODS: We reviewed the literature to assess DDIs reported for the main drugs available for treatment of symptoms/comorbidities frequently encountered by cancer patients. Reviews and relevant original articles cited were retrieved and analyzed, and the following data were collected and double-checked: pharmacological properties; effects, if any, of drugs on CYP enzymes, membrane transporters, and QT interval; and involvement in significant DDIs. RESULTS: A list of preferred drugs with minimal risks of DDIs was compiled. CONCLUSION: Acknowledging for heterogeneity in data sources, prevention of unexpected DDIs during clinical trials may be improved by using this list of preferred drugs for the management of study patient's symptoms
