Biological Anti-IL-5/IL-5R Therapeutics for Chronic Obstructive Pulmonary Disease (COPD) with Specific Treatable Traits: A Real-World Retrospective Analysis.

Introduction: We describe the use of anti-IL-5 monoclonal antibodies from a COPD clinic, a source other than traditional clinical trials. The objectives were to characterize the patient subgroup prescribed anti-IL-5 monoclonal antibodies and to report potential benefits. Methods: This is a retrospective case series study of 17 patients treated in a COPD subspecialty clinic. All patients had a diagnosis of COPD (post-bronchodilator FEV1/FVC <0.7) and had been prescribed an anti-IL-5 biologic for at least 8 months. Acute exacerbations of COPD (AECOPDs) were collected as reported in electronic medical records. Results: All patients (17) enrolled were treated with biologics for ≥8 months, and 13 (76%) for ≥1 year. Patients were characterized by severe disease traits, FEV1 <50% predicted, recurrent exacerbations (3.5 moderate-to-severe AECOPDs in the year before treatment), high peripheral blood eosinophil counts (≥250 cells/µL in the previous year), all on inhaled triple therapy, and only 1 patient with a diagnosis of asthma prior to smoking. There was a statistically significant decrease in the exacerbation rate compared with baseline after 8 and 12 months of anti-IL-5 treatment, respectively, yielding the equivalent of a 2-3x reduction in exacerbation rate. Absolute FEV1 decreased, and the decline in FEV1 % of predicted reached statistical significance (p<0.05); CAT score improved (p<0.05). Discussion: This real-world evidence data aligns with existing studies suggesting the potential benefit of anti-IL-5 treatment for specific patients with COPD and therefore advocates for further investigation of RCTs on the use of anti-IL-5 biologics for well-characterized patients with COPD.

Exploring the advance care planning needs of moderately to severely ill people with COPD.

BACKGROUND: There is no clear consensus on how to approach advance care planning (ACP) with people with chronic obstructive pulmonary disease (COPD). AIM: This study aimed to explore the perceived ACP needs of people with COPD and to investigate the usefulness of a DVD in meeting these needs. METHODS: A qualitative descriptive design was used. Twelve people with moderate to severe COPD were interviewed in an outpatient clinic. RESULTS: From the themes elicited, a mental model was created to demonstrate how the participants engaged in a process of mental work to accept their own mortality and subsequently engage in ACP. CONCLUSIONS: Health professionals should not rely solely on illness severity to initiate ACP. Rather, patients from different illness categories should be approached, but with sensitivity to their emotional cues. Participants who were receptive to end-of-life issues enjoyed the DVD. The DVD is a good medium to facilitate discussion, but would be more effective if patients were screened for readiness prior to viewing.

Innovating the treatment of COPD exacerbations: a phone interactive telesystem to increase COPD Action Plan adherence.

Introduction: Self-management interventions with Written Action Plans and case management support have been shown to improve outcomes in patients with chronic obstructive pulmonary disease (COPD). Novel telehealth technologies may improve self-management interventions. The objectives of this study were to determine whether the use of an interactive phone telesystem increases Action Plan adherence, improves exacerbation recovery and reduces healthcare use in a real-life practice of a COPD clinic. Methods: Initially, 40 patients were followed by a COPD telesystem for 1 year. Detailed data from patients' behaviours during exacerbations was recorded. The telesystem use was then extended to 256 patients from a real-life COPD clinic. Healthcare utilisation for the year before and after telesystem enrolment was then assessed through hospital administrative databases. Results: Thirty-three of the 40 patients completed the initial 1-year study. Eighty-one exacerbations were reported in the 1-year follow-up. Action Plan adherence was observed for 72% of the exacerbations and those who were adherent had a significantly faster exacerbation recovery time. The large-scale implementation of the telesystem resulted in a significant decrease in the proportion of patients with ≥1 respiratory-related emergency room (ER) visits (120 before vs 110 after enrolment, p<0.001) and with ≥1 COPD-related hospitalisations (75 before vs 65 after enrolment, p<0.001). Discussion: COPD Written Action Plan adherence was further enhanced with the use of telehealth technologies in a specialised clinic with experience in COPD self-management. Patients followed by the telesystem recovered faster from exacerbations and had a further decrease in COPD-related ER visits and hospitalisations. Trial registration number: NCT02275078.

Long-term azithromycin therapy to reduce acute exacerbations in patients with severe chronic obstructive pulmonary disease.

RATIONALE: According to clinical trials, azithromycin taken daily for 1 year, decreased exacerbations of chronic obstructive pulmonary disease (COPD). OBJECTIVES: Effectiveness evaluation of long-term azithromycin to reduce exacerbations in severe COPD patient on optimal therapy in real-life practice. METHODS: We conducted a retrospective observational study of severe COPD patients who were prescribed azithromycin (PA)(250 mg, at least 3 times weekly for at least 6 months). Comparison group included severe COPD patients not prescribed azithromycin (NPA). Data were extracted from clinical chart review. MAIN RESULTS: Study included 126 PA and 69 NPA patients. They had severe airflow obstruction, mostly emphysema and one-third bronchiectasis. A predominant feature in the PA group was respiratory tract colonization with Pseudomonas aeruginosa. The mean number of exacerbations per patient per year in the PA group was 3.2 ±â€¯2.1 before initiating azithromycin, and 2.3 ±â€¯1.6 during following year on therapy (p < 0.001). Patients in the NPA group had 1.7 ±â€¯1.3 and 2.5 ±â€¯1.7 exacerbations during first and second follow-up year respectively (p < 0.001). Exacerbation changes from pre to post differed between groups (p < 0.001). Decrease in emergency visits and hospital admissions was significant in PA group. Exacerbation reductions and patient proportions having ≥2 exacerbations extended to the second year of treatment. CONCLUSION: These data showed that long-term azithromycin reduces exacerbation numbers in severe COPD patients, and benefits persist beyond one year. Desirable effects are more likely to outweigh the risks and adverse events in patients colonized with Pseudomonas aeruginosa.

Making collaborative self-management successful in COPD patients with high disease burden.

BACKGROUND: Exacerbations in severe COPD patients lead to challenges in terms of self-management. This study is a "real-life" situation aiming to assess whether or not it is possible for COPD patients with high burden of disease to self-manage acute exacerbations and to reduce hospital use. METHODS: 100 randomly selected charts of patients followed in a specialised COPD clinic in 2006 and 2009 (patients with higher burden of disease) were reviewed. Data on patients' characteristics, COPD severity and exacerbation management were extracted. RESULTS: Compared to the 2006 cohort, patients from the 2009 cohort had lower (0.85 L), but not statistically significant different FEV1 (L) than the 2006 cohort (0.98 L) and more exacerbations (2.6 exacerbations/pt vs 3. 6 exacerbations/pt, p = 0.03). Despite having a higher burden of disease, patients in the 2009 cohort as compared to 2006 had more appropriate self-management behaviours in the event of an exacerbation (60% vs 42%, p = 0.05) and fewer emergency room visits and/or hospital admissions (39% vs 57%, p = 0.02). There were more phone calls to the case managers (590 vs 382, p < 0.001) and fewer physician office visits (167 vs 179, p = 0.024). CONCLUSIONS: This study of a real life situation adds to the current body of literature that a more severe COPD patient population can be taught self-management skills in the event of exacerbations, leading to fewer health care visits and hospital admissions.
