ABSTRACT
BACKGROUND: Discrepancies exist between guidelines and real-life practice in severe asthma. Objectives: To establish profiles for severe asthma patients according to their maintenance therapies and identify unmet needs. METHODS: 2432 French lung specialists and allergists were invited to participate in a severe asthma survey between March and April 2018. Retrospective data were collected using an electronic case report form developed by IQVIA. RESULTS: 71 respiratory physicians and/or allergists participated in the study, providing data for 736 severe asthma patients. The annual mean rates of hospitalization and exacerbation in the previous year were 0.65 (SD = 0.5) and 2.25 (SD = 1.0), respectively. One hundred one (13.7%) patients were treated with oral steroids; the mean dosage regimen was 16.1 mg per day (SD = 11.2). ICS-LABA-LAMA triple inhaled therapy was reported for 288 patients (39%); 231 patients (31.4%) had one biologic in their maintenance treatment. Among patients hospitalized at least once in the previous year (n = 311), 89 (28.5%) were currently treated with biologics, and 61 (19.6%) with oral steroids. One hundred sixty-six patients with uncontrolled asthma and no current biologic therapy had data for "T2 status"; 78 (47%), 89 (53.6%) and 137 (82.5%) of them had treatment criteria respectively for an anti-IgE, anti-IL5-pathway or anti-IL-4/IL-13 pathway therapy; 22 (13.2%) were ineligible for any current biologic according to biomarkers. CONCLUSION: Our study updated "real-life" therapeutic management data for severe asthma in France in 2018. We highlighted a need for improved patient-phenotyping. This work also gives a striking insight of the position of current and forthcoming biologics.
ABSTRACT
PURPOSE: Patients with atrial fibrillation are at increased risk for stroke and thus require anticoagulant prophylaxis with vitamin K antagonists. However, many such patients fail to achieve target coagulation status. The objective of this study was to evaluate time in the therapeutic range and its relationship to clinical outcomes in patients with nonvalvular atrial fibrillation prescribed a vitamin K antagonist in everyday clinical practice in 4 European countries (France, Germany, Italy and the United Kingdom). METHODS: Data were extracted from the European electronic primary care database, the Longitudinal Patient Database. Included in the analysis were 6250 adult patients for whom data on monitoring of coagulation time and international normalized ratio were available. The time within the therapeutic range was estimated by using the Rosendaal method. Patients spending >70% of time within the therapeutic range were considered to have well-controlled treatment. Data on stroke and bleeding events occurring during the study period were taken from patient records. Stroke risk was calculated by using the CHA2DS2-VASc score (i.e. 2 points for a history of stroke or TIA and age >75 years, and 1 point for age between 65 and 74 years, hypertension, diabetes mellitus, a recent cardiac failure, vascular disease and female sex). FINDINGS: The proportion of patients with poorly controlled treatment varied from 34.6% in the United Kingdom to 55.8% in Germany. The incidence of stroke was 0.5/100 person-years in well-controlled patients, compared with 1.0/100 in poorly controlled patients. After adjustment for stroke risk factors, the odds ratio was 1.38 (95% CI, 0.93-2.06; P = 0.110). The incidence of hemorrhage was 1.1 and 1.3 events/100 person-years, respectively (odds ratio, 0.91 [95% CI, 0.72-1.16]). IMPLICATIONS: Many patients receiving prophylaxis with vitamin K antagonists in everyday community care have poorly controlled anticoagulation treatment with vitamin K antagonists. Their international normalized ratio is frequently outside the therapeutic range, and they are thus exposed to an unnecessary risk of stroke or bleeding complications.
