Insights from Social Media on the Patient Experience of Living With Rare Eosinophil-Driven Diseases.

Eosinophilic granulomatosis with polyangiitis (EGPA) and hypereosinophilic syndrome (HES) are driven by persistently high eosinophil numbers, causing damage to tissues and organs. As rare diseases, they are often underappreciated by healthcare professionals. Using a social listening analysis, we collected patient and caregiver comments relating to EGPA and HES made on online social platforms between 1 January 2019 and 31 May 2020, in English, French, and German. Results were classified into key areas of interest. In total, 746 comments with consent to publish were collected mentioning EGPA, and 39 were identified mentioning HES. The most common theme was sharing of personal experiences (EGPA: 77%; HES: 100%). Diagnosis, including diagnosis delays and misdiagnosis, was mentioned in 33% of comments for EGPA, and 82% for HES. Other common themes included seeking and giving advice, symptoms, and treatments. These insights highlight the views and unmet needs of people living with EGPA and HES. Further work should improve disease awareness and effective communications among healthcare professionals and patients with these conditions.

Management of acute COPD exacerbations in France: A qualitative survey in a private practice setting.

BACKGROUND: The current prevalence of chronic obstructive pulmonary disease (COPD) in France is estimated to be 2.6 million and is predicted to increase to 2.8 million by 2025. Presently, there is a lack of data on COPD management within the private healthcare setting. The aim of this study was to investigate the management of COPD exacerbations by pulmonologists within private practices in France. METHODS: A prospective, online, qualitative survey was distributed to private practice pulmonologists in France. The survey covered all aspects of COPD management from diagnosis and therapeutic management, to secondary prevention and organization of care. Survey responses were collected between 27 January 2018 and 18 June 2018 and all data were summarized descriptively. RESULTS: The survey had a response rate of 20.6%, with 116 out of 563 pulmonologists providing responses. Overall, 87.4% of respondents stated that the management of COPD represented over 15% of their total clinical activity. Most respondents indicated that they work closely with general practitioners and a large multidisciplinary team to manage patients with numerous comorbidities. Following a COPD exacerbation, the majority of respondents (78.4%) were in favor of using respiratory-connected devices (class 2a-connected medical device according to the French HAS classification and available on medical prescription) to assist with patient follow-up at home. CONCLUSIONS: COPD management forms part of the core clinical activity for pulmonologists within the private practice setting in France. Patients with COPD generally have multiple comorbidities and are managed by a multidisciplinary team in line with French guidelines. The use of respiratory-connected devices was highlighted as an important new strategy for improving patient care following a COPD exacerbation.

Efficacy and safety of once-daily fluticasone furoate/vilanterol (FF/VI) versus twice-daily inhaled corticosteroids/long-acting ß2-agonists (ICS/LABA) in patients with uncontrolled asthma: An open-label, randomized, controlled trial.

BACKGROUND: A variety of different fixed-dose combinations of inhaled corticosteroids/long-acting ß2-agonists (ICS/LABA) are available for the treatment of asthma. The aim of this 24-week, open-label, multicenter, Phase IIIb randomized controlled trial was to evaluate the efficacy and safety of once-daily fluticasone furoate/vilanterol (FF/VI; 100/25 or 200/25 µg) compared with twice-daily fixed combinations of ICS/LABA (fluticasone propionate/salmeterol [FP/S] and budesonide/formoterol [BUD/F]) as maintenance therapy in patients with uncontrolled asthma treated with ICS alone. METHODS: Adult patients with documented physician-diagnosed asthma ≥1 year with an Asthma Control Test (ACT) score ≥15 and < 20 were included. The primary study endpoint was change from baseline in ACT total score at Week 12. RESULTS: Overall, 423 patients were randomized to receive study medication in France and Germany. The least-squares mean change (standard error) in ACT total score at Week 12 was 3.6 units with FF/VI and 2.8 with usual ICS/LABA, giving a treatment difference of 0.8 (95% confidence interval 0.1, 1.5; p = 0.033). Non-inferiority of FF/VI to usual ICS/LABA was confirmed at Weeks 6, 18 and 24. The observed safety profile for FF/VI in this study was in line with previous experience with FF/VI. CONCLUSIONS: These findings suggest that, in a tightly controlled randomized controlled trial setting, once-daily FF/VI provides similar asthma control over 24 weeks to usual, twice-daily ICS/LABA in patients with asthma that is uncontrolled on ICS alone. FF/VI was well tolerated.

Collection of human biological samples for research purpose: Key challenges and patients' perspectives.

The development and the access to collections of human biological samples is one of the major challenges for health research. In recent years, biological resource centres (BRCs) have developed in such a way that they provide all activities relating to the handling of samples. In this context, France is undoubtedly a pioneering country, because most of the biological collections available were created on the basis of themed research projects, which involved a particular donor phenotype. The round table was an opportunity to emphasise the persistence of some pitfalls particularly in relation to ensuring the consistency of different regulatory pathways. It also gave the opportunity to question and make recommendations on aspects of governance of biological collections and the BRCs, to state the challenges linked to scientific and economic valorisation and to consider the place of patients and the general public. The development of specific education in public health and research is essential to underline that these initiatives are necessary for developing new diagnostic and therapeutic procedures.

Stereoselective Rearrangement of (Trifluoromethyl)prolinols to Enantioenriched 3-Substituted 2-(Trifluoromethyl)piperidines.

3-Substituted 2-(trifluoromethyl)piperidines B were synthesized by ring expansion of (trifluoromethyl)prolinols A, which were obtained from L-proline via an aziridinium intermediate C. The ring opening of the (trifluoromethyl)aziridinium intermediate by different nucleophiles is regio- and diastereoselective.

Genotypic resistance analysis of the virological response to fosamprenavir-ritonavir in protease inhibitor-experienced patients in CONTEXT and TRIAD clinical trials.

The aim of this study was to identify human immunodeficiency virus (HIV) protease mutations associated with virological response (VR) to fosamprenavir-ritonavir (FPV/r) in 113 protease inhibitor (PI)-experienced patients randomized in both CONTEXT and TRIAD clinical trials and receiving the same dose (700/100 mg twice daily) of FPV/r. The impact of each protease mutation on the VR to FPV/r, defined as the decrease in HIV RNA at week 12, was investigated with nonparametric analyses. A step-by-step procedure was done using a Jonckheere-Terpstra (JT) test that retains the group of mutations most strongly associated with the VR. Mutations at the following 14 codons were associated with a reduced VR to FPV/r: 10, 15, 33, 46, 54, 60, 62, 63, 72, 73, 82, 84, 89, and 90. The JT procedure led to selecting the CONTEXT/TRIAD genotypic set of mutations, I15V, M46I/L, I54L/M/V, D60E, L63P/T, and I84V, as providing the strongest association with the VR (P = 1.45 x 10(-11)). In the nine patients with zero mutations within this set, the median decrease in HIV RNA was -2.63 log copies/ml, and was -2.22 (n = 45), -1.50 (n = 26), -0.58 (n = 23), -0.47 (n = 6), -0.13 (n = 3), and 0.04 (n = 1) log copies/ml in those with one, two, three, four, five, and six mutations, respectively. This study identified six mutations associated with VR to FPV/r. Some of these mutations are shared with the current FPV/r Agence Nationale de Recherches sur le SIDA (ANRS) resistance score, which has been cross-validated in the CONTEXT/TRIAD data set, suggesting that the current ANRS FPV/r score is a useful tool for the prediction of VR to FPV/r in PI-experienced patients.

Comparison of metabolic abnormalities and clinical lipodystrophy 48 weeks after switching from HAART to Trizivir versus continued HAART: the Trizal study.

PURPOSE: To analyze the evolution of clinical lipodystrophy (LD) and metabolic abnormalities in patients continuing to receive HAART versus patients switched to Trizivir (zidovudine, lamivudine, abacavir) after 48 weeks. METHOD: Patients treated with HAART >6 months with plasma HIV-1 RNA viral load (VL) <400 copies/mL and <50 copies/mL at screening were randomly assigned to continue HAART (103 patients) or to receive Trizivir (106 patients). Clinical LD was evaluated using a standardized patient questionnaire only at baseline, weeks 4 and 8, and then every 8 weeks until Week 48. Laboratory evaluation was performed every 4 weeks. RESULTS: The proportion of patients exhibiting >or=1 LD symptom at baseline was 40% in the Trizivir arm and 50% in HAART arm (difference not significant). After 48 weeks, the prevalence was 28% and 42% respectively (p =.03), and the median number of LD symptoms per patient was 2 in the Trizivir arm and 4 in the continued HAART arm (p =.016). Median decreases in cholesterol levels over the 48-week study period were greater in the Trizivir arm than in the continued HAART arm (-0.80 vs. -0.44 mmol/L; p lt.001). Median triglyceride levels decreased in the Trizivir arm but increased in the continued HAART arm (-0.17 and +0.01 mmol/L; p =.006). Suppression of VL was maintained in most patients with no differences between the two arms. CONCLUSION: A switch from "standard" HAART to Trizivir was associated with an improvement in clinical LD and blood lipid abnormalities after 48 weeks.
