For more than 50 years, small airways disease has been considered a key feature of chronic obstructive pulmonary disease (COPD) and a major cause of airway obstruction. Both preventable and treatable, small airways disease has important clinical consequences if left unchecked. Small airways disease is associated with poor spirometry results, increased lung hyperinflation, and poor health status, making the small airways an important treatment target in COPD. The early detection of small airways disease remains the key barrier; if detected early, treatments designed to target small airways may help reduce symptoms and allow patients to maintain their activities. Studies are needed to evaluate the possible role of new drugs and novel drug formulations, inhalers, and inhalation devices for treating small airways disease. These developments will help to improve our management of small airways disease in patients with COPD.

Objectives. To synthesize existing knowledge about the effectiveness and harms of pharmacologic and nonpharmacologic treatments for exacerbations of chronic obstructive pulmonary disease (ECOPD).

Data sources. Embase®, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, MEDLINE® Daily, MEDLINE, Cochrane Central Registrar of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus from database inception to January 2, 2019.

Review methods. We included randomized controlled trials (RCTs) that evaluated pharmacologic intervention or nonpharmacologic interventions for ECOPD. The strength of evidence (SOE) was graded for critical final health outcomes.

Results. We included 98 RCTs (13,401 patients, mean treatment duration 9.9 days, mean followup 3.7 months). Final health outcomes, including mortality, resolution of exacerbation, hospital readmissions, repeat exacerbations, and need for intubation, were infrequently evaluated and often showed no statistically significant differences between groups. Antibiotic therapy increases the clinical cure rate and reduces the clinical failure rate regardless of the severity of ECOPD (moderate SOE). There is insufficient evidence to support a particular antibiotic regimen. Oral and intravenous corticosteroids improve dyspnea and reduce the clinical failure rate (low SOE). Despite the ubiquitous use of inhaled bronchodilators in ECOPD, we found only a small number of trials that assessed lung function tests, and not final health outcomes. The evidence is insufficient to support the effect of aminophyllines, magnesium sulfate, mucolytics, inhaled corticosteroids, inhaled antibiotics, 5-lipoxygenase inhibitor, and statins on final health outcomes. Titrated oxygen reduces mortality compared with high flow oxygen (low SOE). Low SOE suggested benefit from some nonpharmacologic interventions such as chest physiotherapy using vibration/percussion/massage or breathing technique (on dyspnea), resistance training (on dyspnea and quality of life), early pulmonary rehabilitation commenced before hospital discharge during the initial most acute phase of exacerbation rather than the convalescence period (on dyspnea) and whole body vibration training (on quality of life). Vitamin D supplementation may improve quality of life (low SOE).

Conclusions. Although chronic obstructive pulmonary disease is a common condition, the evidence base for most interventions in ECOPD remains limited. Systemic antibiotics and corticosteroids are associated with improved outcomes in mild and moderate to severe ECOPD. Titrated oxygen reduces mortality. Future research is required to assess the effectiveness of several emerging nonpharmacologic and dietary treatments.

BACKGROUND:

The efficacy and safety of benralizumab, an interleukin-5 receptor alpha-directed cytolytic monoclonal antibody, for the prevention of exacerbations in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) are not known.

METHODS:

In the GALATHEA and TERRANOVA trials, we enrolled patients with COPD (at a ratio of approximately 2:1 on the basis of eosinophil count [≥220 per cubic millimeter vs. <220 per cubic millimeter]) who had frequent exacerbations despite receiving guideline-based inhaled treatment. Patients were randomly assigned to receive benralizumab (30 or 100 mg in GALATHEA; 10, 30, or 100 mg in TERRANOVA) every 8 weeks (every 4 weeks for the first three doses) or placebo. The primary end point was the treatment effect of benralizumab, measured as the annualized COPD exacerbation rate ratio (benralizumab vs. placebo) at week 56 in patients with baseline blood eosinophil counts of 220 per cubic millimeter or greater. Safety was also assessed.

RESULTS:

In GALATHEA, the estimates of the annualized exacerbation rate were 1.19 per year (95% confidence interval [CI], 1.04 to 1.36) in the 30-mg benralizumab group, 1.03 per year (95% CI, 0.90 to 1.19) in the 100-mg benralizumab group, and 1.24 per year (95% CI, 1.08 to 1.42) in the placebo group; the rate ratio as compared with placebo was 0.96 for 30 mg of benralizumab (P = 0.65) and 0.83 for 100 mg of benralizumab (P = 0.05). In TERRANOVA, the estimates of the annualized exacerbation rate for 10 mg, 30 mg, and 100 mg of benralizumab and for placebo were 0.99 per year (95% CI, 0.87 to 1.13), 1.21 per year (95% CI, 1.08 to 1.37), 1.09 per year (95% CI, 0.96 to 1.23), and 1.17 per year (95% CI, 1.04 to 1.32), respectively; the corresponding rate ratios were 0.85 (P = 0.06), 1.04 (P = 0.66), and 0.93 (P = 0.40). At 56 weeks, none of the annualized COPD exacerbation rate ratios for any dose of benralizumab as compared with placebo reached significance in either trial. Types and frequencies of adverse events were similar with benralizumab and placebo.

CONCLUSIONS:

Add-on benralizumab was not associated with a lower annualized rate of COPD exacerbations than placebo among patients with moderate to very severe COPD, a history of frequent moderate or severe exacerbations, and blood eosinophil counts of 220 per cubic millimeter or greater (Funded by AstraZeneca [GALATHEA and TERRANOVA] and Kyowa Hakko Kirin [GALATHEA]; GALATHEA and TERRANOVA ClinicalTrials.gov numbers, NCT02138916 and NCT02155660.).

In adults with acute COPD exacerbations, serum CRP-based decision-making led to fewer antibiotic prescriptions with no adverse consequences. Physicians and patients in the intervention group were advised to consider all clinically relevant information. However, they were advised to consider that CRP levels < 4omg/L indicated that antibiotics were probably not needed, levels between 20 and 40 mg/L were indeterminant, and levels above 40 mg/L suggested that antibiotics were probably necessary. Note: In this study, physicians were able to obtain CRP levels at the point of care. James W. Mold, MD, MPH

BACKGROUND

Point-of-care testing of C-reactive protein (CRP) may be a way to reduce unnecessary use of antibiotics without harming patients who have acute exacerbations of chronic obstructive pulmonary disease (COPD).

METHODS

We performed a multicenter, open-label, randomized, controlled trial involving patients with a diagnosis of COPD in their primary care clinical record who consulted a clinician at 1 of 86 general medical practices in England and Wales for an acute exacerbation of COPD. The patients were assigned to receive usual care guided by CRP point-of-care testing (CRP-guided group) or usual care alone (usual-care group). The primary outcomes were patient-reported use of antibiotics for acute exacerbations of COPD within 4 weeks after randomization (to show superiority) and COPD-related health status at 2 weeks after randomization, as measured by the Clinical COPD Questionnaire, a 10-item scale with scores ranging from 0 (very good COPD health status) to 6 (extremely poor COPD health status) (to show noninferiority).

RESULTS

A total of 653 patients underwent randomization. Fewer patients in the CRP-guided group reported antibiotic use than in the usual-care group (57.0% vs. 77.4%; adjusted odds ratio, 0.31; 95% confidence interval [CI], 0.20 to 0.47). The adjusted mean difference in the total score on the Clinical COPD Questionnaire at 2 weeks was −0.19 points (two-sided 90% CI, −0.33 to −0.05) in favor of the CRP-guided group. The antibiotic prescribing decisions made by clinicians at the initial consultation were ascertained for all but 1 patient, and antibiotic prescriptions issued over the first 4 weeks of follow-up were ascertained for 96.9% of the patients. A lower percentage of patients in the CRP-guided group than in the usual-care group received an antibiotic prescription at the initial consultation (47.7% vs. 69.7%, for a difference of 22.0 percentage points; adjusted odds ratio, 0.31; 95% CI, 0.21 to 0.45) and during the first 4 weeks of follow-up (59.1% vs. 79.7%, for a difference of 20.6 percentage points; adjusted odds ratio, 0.30; 95% CI, 0.20 to 0.46). Two patients in the usual-care group died within 4 weeks after randomization from causes considered by the investigators to be unrelated to trial participation.

CONCLUSIONS

CRP-guided prescribing of antibiotics for exacerbations of COPD in primary care clinics resulted in a lower percentage of patients who reported antibiotic use and who received antibiotic prescriptions from clinicians, with no evidence of harm.

Inhaler Technique Education and Exacerbation Risk in Older Adults with Asthma or Chronic Obstructive Pulmonary Disease: A Meta‐Analysis

The meta-analysis of 4 RCTs found that patients with COPD and 25-hydroxy Vitamin D levels below 25 had fewer moderate and severe COPD exacerbations if they were supplemented with Vitamin D. It suggests that COPD patients should have their Vitamin D levels measured periodically, and if their levels are below 25, they should be supplemented.

BACKGROUND:

Randomised controlled trials (RCTs) of vitamin D to prevent COPDexacerbations have yielded conflicting results.Individual participant data meta-analysis could identify factors that explain this variation.

METHODS:

PubMed, Embase, the Cochrane Central Register of Controlled Trials and Web of Science were searched from inception up to and including 5 October 2017 to identify RCTs of vitamin D supplementation in patients with COPD that reported incidence of acute exacerbations. Individual participant data meta-analysis was performed using fixed effects models adjusting for age, sex, Global Initiative for Chronic Obstructive Lung Disease spirometric grade and trial.

RESULTS:

Four eligible RCTs (total 560 participants) were identified; individual participant datawere obtained for 469/472 (99.4%) participants in three RCTs. Supplementation did not influence overall rate of moderate/severe COPD exacerbations (adjusted incidence rate ratio (aIRR) 0.94, 95% CI 0.78 to 1.13). Prespecified subgroup analysis revealed that protective effects were seen in participants with baseline 25-hydroxyvitamin D levels <25 nmol/L (aIRR 0.55, 95% CI 0.36 to 0.84) but not in those with baseline 25-hydroxyvitamin D levels ≥25 nmol/L (aIRR 1.04, 95% CI 0.85 to 1.27; p for interaction=0.015). Vitamin D did not influence the proportion of participants experiencing at least one serious adverse event (adjusted OR 1.16, 95% CI 0.76 to 1.75).

CONCLUSIONS:

Vitamin D supplementation safely and substantially reduced the rate of moderate/severe COPD exacerbations in patients with baseline 25-hydroxyvitamin D levels <25 nmol/L but not in those with higher levels.

This meta-analysis, focused on COPD patients, is a reminder of the importance of training patients to use their inhalers properly. That suggests that practices have at least one inhaler trainer and placebo inhalers or that patients requiring inhalers should be referred to a respiratory therapist or pharmacist for training.

Objectives

To evaluate the effect of inhaler education programs on clinical outcomes and exacerbation rates in older adults with asthma or chronic obstructive pulmonary disease (COPD).

Design

Systematic review and meta‐analysis.

Setting and Participants

Older adults with asthma or COPD, either in primary or secondary health care and pharmacy setting.

Measurements

We searched the Medline, Embase, and Central databases according to the main eligibility criteria for inclusion: systematic reviews, meta‐analysis, clinical trials and quasi‐experimental studies; participants aged 65 and older; education on inhaler technique and reporting of disease control and exacerbation rates. We used the Grading of Recommendations, Assessment, Development and Evaluations scale for quality assessment and used a random‐effect model with Mantel–Haenszel adjustment to perform a meta‐analysis.

Results

We included 8 studies (4 randomized, 4 quasi‐experimental) with a total of 1,812 participants. The most frequent type of intervention was physical demonstration of inhaler technique, training with placebo devices. Five studies showed significant reduction in exacerbation rates (pooled risk ratio=0.71, 95% confidence interval=0.59–0.86; p < .001), although effect on disease control and quality of life showed high discrepancy in the reported results, and all randomized studies revealed uncertainty in their risk of bias assessment.

Conclusion

All interventions seemed to improve inhaler performance and clinically relevant outcomes, but a placebo device could be the most effective. There is evidence that interventions reduce exacerbation risk in older adults, although to an overall moderate degree.
