Prevalence and disparities in influenza vaccination among patients with COPD: A French nationwide population study.

INTRODUCTION: Despite concordant international recommendations, many surveys found disappointing rates of influenza vaccination in at-risk populations, ranging from 23% in overall COPD population to more than 70% in more severe COPD subjects. Therefore, we assessed the proportion of French COPD patients non-vaccinated for influenza and their clinical and socio-demographic factors. MATERIEL AND METHODS: This was a national retrospective study based on the French health insurance database. We identified "diagnosed COPD", defined as subjects hospitalized at least once in 2017 with a principal or associated diagnosis of COPD, and "suspected COPD" as those who were prescribed at least thrice long-acting bronchodilators (LAB), after exclusion of patients with a principal diagnosis or secondary associated diagnosis of asthma or cystic fibrosis, patients deceased before the influenza season and patients hospitalized in long-term or in palliative care unit. Multivariate logistic regression was used to assess the association between patients' characteristics and the lack of influenza vaccination. RESULTS: From the national database, 1 474 396 subjects were identified as "suspected COPD" of whom 528 114 were excluded because of previous diagnosis of asthma or cystic fibrosis, and 350 566 as "diagnosed COPD". Among the 1 296 848 patients included, 646 687 patients (53.3%) were vaccinated against influenza. Non-vaccinated subjects were significantly younger (62.1 vs 71.6 years old), more often women (47.9% vs 43.1%) and had fewer comorbidities assessed by Charlson's index (3.0 ± 2.2 vs 4.3 ± 2.1). Lack of vaccination was also associated with a lower LAB usage. Also, non-vaccinated subjects neither had severe exacerbation during the study period. Besides there was a significant heterogeneity in vaccination rate by geographic region, from 47% to 57%. In multivariate analysis, variables independently associated with the lack of influenza vaccination were female gender, younger age, fewer comorbidities and lower socio-economic level. CONCLUSIONS: This study using the French exhaustive health insurance database shows that influenza vaccination among COPD patients remains dramatically low and must become a high-priority public-health strategy.

[Medication management of COPD]. / Prise en charge médicamenteuse de la BPCO.

MEDICATION MANAGEMENT OF COPD. The management of chronic obstructive pulmonary disease (COPD) is based on drug and non-drug measures. Inhaled therapies are the major issues including the use of short-acting bronchodilators for respiratory symptoms. If symptoms are daily, such as disabling dyspnea or frequent exacerbations, daily treatment with a long-acting bronchodilator is proposed: anti-muscarinic (LAMA) or ß2-agonist (LABA). If there is no improvement, escalation to dual and then triple therapy is proposed. Another major issue in the management of COPD is de-escalation in the event of ineffectiveness or side effects of inhaled corticosteroids (ICS). Finally, the role of blood eosinophils and other biomarkers is even more important that biotherapies could expand the therapeutic options for some subtypes of COPD patients.

PRISE EN CHARGE MÉDICAMENTEUSE DE LA BPCO. La prise en charge de la bronchopneumopathie chronique obstructive (BPCO) repose sur des mesures médicamenteuses et non médicamenteuses. Le principe des traitements médicamenteux dans la BPCO comprend des traitements inhalés, et notamment l'utilisation de bronchodilatateurs de courte durée d'action en cas de symptômes respiratoires. Si les symptômes sont quotidiens à type de dyspnée invalidante ou en cas d'exacerbations fréquentes, un traitement de fond quotidien par un bronchodilatateur de longue durée d'action est indiqué : antimuscarinique (LAMA) ou ß2-agoniste (LABA). En l'absence d'amélioration, une escalade est proposée par bithérapie puis trithérapie. Un autre enjeu majeur de la prise en charge de la BPCO est la désescalade thérapeutique en cas d'inefficacité ou d'effets indésirables des corticostéroïdes inhalés (CSI). Enfin, la place du dosage des éosinophiles et autres biomarqueurs sanguins est d'autant plus importante que les biothérapies pourraient venir élargir l'arsenal thérapeutique pour certains soustypes de patients atteints de BPCO.

Brief Report: Severe Sotorasib-Related Hepatotoxicity and Non-Liver Adverse Events Associated With Sequential Anti-Programmed Cell Death (Ligand)1 and Sotorasib Therapy in KRASG12C-Mutant Lung Cancer.

INTRODUCTION: Sequential anti-programmed cell death protein 1 (PD-1) or anti-programmed death-ligand 1 (PD-L1) followed by small targeted therapy use is associated with increased prevalence of adverse events (AEs) in NSCLC. KRASG12C inhibitor sotorasib may trigger severe immune-mediated hepatotoxicity when used in sequence or in combination with anti-PD-(L)1. This study was designed to address whether sequential anti-PD-(L)1 and sotorasib therapy increases the risk of hepatotoxicity and other AEs. METHODS: This is a multicenter, retrospective study of consecutive advanced KRASG12C-mutant NSCLC treated with sotorasib outside clinical trials in 16 French medical centers. Patient records were reviewed to identify sotorasib-related AEs (National Cancer Institute Common Classification Criteria for Adverse Events-Version 5.0). Grade 3 and higher AE was considered as severe. Sequence group was defined as patients who received an anti-PD-(L)1 as last line of treatment before sotorasib initiation and control group as patients who did not receive an anti-PD-(L)1 as last line of treatment before sotorasib initiation. RESULTS: We identified 102 patients who received sotorasib, including 48 (47%) in the sequence group and 54 (53%) in the control group. Patients in the control group received an anti-PD-(L)1 followed by at least one treatment regimen before sotorasib in 87% of the cases or did not receive an anti-PD-(L)1 at any time before sotorasib in 13% of the cases. Severe sotorasib-related AEs were significantly more frequent in the sequence group compared with those in the control group (50% versus 13%, p < 0.001). Severe sotorasib-related AEs occurred in 24 patients (24 of 48, 50%) in the sequence group, and among them 16 (67%) experienced a severe sotorasib-related hepatotoxicity. Severe sotorasib-related hepatotoxicity was threefold more frequent in the sequence group compared with that in the control group (33% versus 11%, p = 0.006). No fatal sotorasib-related hepatotoxicity was reported. Non-liver severe sotorasib-related AEs were significantly more frequent in the sequence group (27% versus 4%, p < 0.001). Severe sotorasib-related AEs typically occurred in patients who received last anti-PD-(L)1 infusion within 30 days before sotorasib initiation. CONCLUSIONS: Sequential anti-PD-(L)1 and sotorasib therapy are associated with a significantly increased risk of severe sotorasib-related hepatotoxicity and severe non-liver AEs. We suggest avoiding starting sotorasib within 30 days from the last anti-PD-(L)1 infusion.

Pulmonary rehabilitation after severe exacerbation of COPD: a nationwide population study.

BACKGROUND: Acute exacerbations of chronic obstructive pulmonary disease (COPD) lead to a significant reduction in quality of life and an increased mortality risk. Current guidelines strongly recommend pulmonary rehabilitation (PR) after a severe exacerbation. Studies reporting referral for PR are scarce, with no report to date in Europe. Therefore, we assessed the proportion of French patients receiving PR after hospitalization for COPD exacerbation and factors associated with referral. METHODS: This was a national retrospective study based on the French health insurance database. Patients hospitalized in 2017 with COPD exacerbation were identified from the exhaustive French medico-administrative database of hospitalizations. In France, referral to PR has required as a stay in a specialized PR center or unit accredited to provide multidisciplinary care (exercise training, education, etc.) and admission within 90 days after discharge was assessed. Multivariate logistic regression was used to assess the association between patients' characteristics, comorbidities according to the Charlson index, treatment, and PR uptake. RESULTS: Among 48,638 patients aged ≥ 40 years admitted for a COPD exacerbation, 4,182 (8.6%) received PR within 90 days after discharge. General practitioner's (GP) density (number of GPs for the population at regional level) and PR center facilities (number of beds for the population at regional level) were significantly correlated with PR uptake (respectively r = 0.64 and r = 0.71). In multivariate analysis, variables independently associated with PR uptake were female gender (aOR 1.36 [1.28-1.45], p < 0.0001), age (p < 0.0001), comorbidities (p = 0.0013), use of non-invasive ventilation and/or oxygen therapy (aOR 1.52 [1.41-1.64], p < 0.0001) and administration of long-acting bronchodilators (p = 0.0038). CONCLUSION: This study using the French nationally exhaustive health insurance database shows that PR uptake after a severe COPD exacerbation is dramatically low and must become a high-priority management strategy.

Second-line lurbinectedin as a new treatment option for small-cell lung cancer: Preliminary results in real-clinical practice.

INTRODUCTION: Few strategies exist for treatment of patients with small-cell lung cancer (SCLC) extended-stage after failure of first-line platinum-based chemotherapy. Lurbinectedin is a novel RNA-polymerase-II inhibitor investigated as a second-line therapy for SCLC. However, its efficacy and safety profile in real clinical practice remain to be determined. OBJECTIVE: To determine the efficacy and safety of lurbinectedin in real-life among patients with SCLC previously treated with first-line platinum-based chemotherapy. METHODS: We retrospectively evaluated patients who received at least one dose of lurbinectedin (3.2 mg/m2 ) between March 2020 and November 2021, in the pulmonary department of Bordeaux University Hospital. Endpoints were time to treatment discontinuation, progression-free survival, overall survival, and safety profile. RESULTS: Thirteen patients were included. The median age was 60 years (range: 42-77), seven (54%) were females, nine (69%) having a performance status of 0-1. Lurbinectedin was given as second-line treatment before platinum rechallenge in four (31%) patients. After a mean follow-up of 4.1 months, the objective response rate (ORR) was 17%. The median time to treatment discontinuation (TTD) was 2.3 months (interquartile range [IQR], 1.2-3.6). The median progression-free survival (PFS) and overall survival (OS) were, respectively, 1.9 (IQR, 0.1.8) and 4.1 (IQR, 2.0-3.5) months. No significant difference regarding TTD, PFS or OS was found in the two groups according to treatment history or according to chemotherapy-free intervall (CMI) 〈1 or 〉1 month. The most common adverse events (AEs) were asthenia, nausea, and anemia in nine (70%) patients. Grade 3 AEs were reported, fatigue, vomiting, nausea, anorexia, and neutropenia. CONCLUSIONS: Lurbinectedin in real clinical practice could have had a lower efficacy than in phase II trial, but a better hematological and bioclinical tolerance than previously reported. Early relapse after platinum-based chemotherapy seems to have a lower response to lurbinectedin.
