COPD

Triple therapy with an inhaled corticosteroid is particularly helpful for patients with chronic obstructive pulmonary disease (COPD) who have high baseline eosinophil counts, a trial involving more than 10,000 patients found.

Former smokers received greater benefit from inhaled corticosteroids (ICS) than did current smokers, reported lead author Steven Pascoe, MBBS, of GlaxoSmithKline and colleagues. The investigators noted that these findings can help personalize therapy for patients with COPD, which can be challenging to treat because of its heterogeneity. The study was published in Lancet Respiratory Medicine.

The phase 3 IMPACT trial compared single-inhaler fluticasone furoate–umeclidinium–vilanterol with umeclidinium-vilanterol and fluticasone furoate–vilanterol in patients with moderate to very severe COPD at high risk of exacerbation. Of the 10,333 patients involved, approximately one-quarter (26%) had one or more severe exacerbations in the previous year and half (47%) had two or more moderate exacerbations in the same time period. All patients were symptomatic and were aged 40 years or older. A variety of baseline and demographic patient characteristics were recorded, including blood eosinophil count, smoking status, and others. Responses to therapy were measured with trough forced expiratory volume in 1 second (FEV₁), symptom scoring, and a quality of life questionnaire.

After 52 weeks, results showed that higher baseline eosinophil counts were associated with progressively greater benefits in favor of triple therapy. For patients with baseline blood eosinophil counts of at least 310 cells per mcL, triple therapy was associated with about half as many moderate and severe exacerbations as treatment with umeclidinium-vilanterol (rate ratio = 0.56; 95% confidence interval, 0.47-0.66). For patients with less than 90 cells per mcL at baseline, the rate ratio for the same two regimens was 0.88, but with a confidence interval crossing 1 (0.74-1.04). For fluticasone furoate–vilanterol vs. umeclidinium-vilanterol, high baseline eosinophil count again demonstrated its predictive power for ICS efficacy, again with an associated rate ratio of 0.56 (0.47-0.66), compared with 1.09 (0.91-1.29) for patients below the lower threshold. Symptom scoring, quality of life, and FEV₁ followed a similar trend, although the investigators noted that this was “less marked” for FEV₁. Although the trend held regardless of smoking status, benefits were more pronounced among former smokers than current smokers.

“In former smokers, ICS benefits were observed at all blood eosinophil counts when comparing triple therapy with umeclidinium-vilanterol, whereas in current smokers no ICS benefit was observed at lower eosinophil counts, less than approximately 200 eosinophils per [mcL],” the investigators wrote.

“Overall, these results show the potential use of blood eosinophil counts in conjunction with smoking status to predict the magnitude of ICS response within a dual or triple-combination therapy,” the investigators concluded. “Future approaches to the pharmacological management of COPD should move beyond the simple dichotomization of each clinical or biomarker variable, toward more complex algorithms that integrate the interactions between important variables including exacerbation history, smoking status, and blood eosinophil counts.”

The study was funded by GlaxoSmithKline. The investigators disclosed additional relationships with AstraZeneca, Boehringer Ingelheim, Chiesi, CSA Medical, and others.

Chronic obstructive pulmonary disease (COPD) is often heterogeneous in its presentation and prognosis, and neither pulmonary function tests nor CT alone are always adequate to characterize a patient’s disease. Combining visual and quantitative information from these clinical tests, however, can allow physicians to more precisely subtype COPD and assess patients’ risk, a study has found.

In a paper published in CHEST, Jinkyeong Park, MD, PhD, of Dongguk University Ilsan Hospital in Goyang, South Korea, and colleagues looked at data from 9,080 subjects enrolled in the COPDGene study, an observational cohort of longtime smokers with and without COPD. By assessing visually defined patterns of emphysema with quantitative imaging features and spirometry data, the researchers identified 10 distinct subtypes of COPD (including no disease) and noted significant differences in mortality and progression among them.

Dr. Park and colleagues found that patients in the subgroups with quantitative but no visual emphysema and those with visual but not quantitative emphysema represented unique groups with mild COPD that were both at risk for progression – but with likely different underlying mechanisms. Current smokers, women, and whites were more common among subjects showing visually defined emphysema without quantitative evidence. “Many of the subjects in the visual-only emphysema subtype have areas of low lung density due to emphysema masked by smoking-induced lung inflammation,” the researchers wrote.

Overall 5-year mortality differed significantly among the groups (P less than .01) and was highest in the three groups with moderate to severe centrilobular emphysema. Patients with paraseptal and moderate to severe centrilobular emphysema showed substantial progression of emphysema over 5 years, compared with individuals with no CT abnormality (P less than .05).

“These results suggest that the combination of visual and quantitative CT features, which may reflect different underlying pathobiological processes in COPD, may provide a superior approach to classify individuals with COPD, compared to the use of visual or quantitative CT features alone,” the researchers wrote.

The study received funding from the National Heart, Lung and Blood Institute. Three of the study’s coauthors reported conflicts of interest in the form of patent applications or financial support from pharmaceutical firms.

Patients with chronic obstructive pulmonary disease are at a significantly increased risk for hospitalization for community-acquired pneumonia (CAP), compared with patients without COPD, a large prospective study has found.

Jose Bordon, MD, and colleagues aimed to define incidence and outcomes of COPD patients hospitalized with pneumonia in the city of Louisville, Ky., and to extrapolate the burden of disease in the U.S. population. They conducted a secondary analysis of data from the University of Louisville Pneumonia Study, a prospective population-based cohort study of all hospitalized adults with CAP who were residents in the city of Louisville, Ky., from June 1, 2014, to May 31, 2016.

COPD prevalence in the city of Louisville was derived via data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) as well as from the 2014 National Health Interview Survey (NHIS). In addition, the researchers analyzed clinical outcomes including time to clinical stability (TCS), length of hospital stay (LOS), and mortality, according to Dr. Bordon, an infectious disease specialist at Providence Health Center, Washington, and colleagues on behalf of the University of Louisville Pneumonia Study Group.

The researchers found an 18-fold greater incidence of community-acquired pneumonia in patients with COPD, compared with non-COPD patients.

A total of 18,246 individuals aged 40 and older with COPD were estimated to live in Louisville, Ky. The researchers found that 3,419 COPD patients were hospitalized due to CAP in Louisville during the 2-year study period. COPD patients, compared with non-COPD patients, were more likely to have a history of heart failure, more ICU admissions, and use of mechanical ventilation, compared with patients without COPD. The two groups had similar pneumonia severity index scores, and 17% received oral steroids prior to admission. COPD patients had more pneumococcal pneumonia, despite receiving pneumococcal vaccine significantly more often than non-COPD patients.

The annual incidence of hospitalized CAP was 9,369 cases per 100,000 COPD patients in the city of Louisville. In the same period, the incidence of CAP in patients without COPD was 509 per 100,000, a more than 18-fold difference.

Although the incidence of CAP in COPD patients was much higher than in those without, the difference didn’t appear to have an impact on clinical outcomes. There were no clinical differences among patients with vs. without COPD in regard to time to reach clinical improvement and time of hospital discharge, and in-hospital mortality was not statistically significantly different between the groups, the authors reported. The mortality of COPD patients during hospitalization, at 30 days, at 6 months, and at 1 year was 5.6% of patients, 11.9%, 24.3%, and 33.0%, respectively vs. 6.6%, 14.2%, 24.2%, and 30.1% in non-COPD patients. However, 1-year all-cause mortality was a significant 25% greater among COPD patients, as might be expected by the progression and effects of the underlying disease.

“[Our] observations mean that nearly 1 in 10 persons with COPD will be hospitalized annually due to CAP. This translates into approximately 500,000 COPD patients hospitalized with CAP every year in the U.S., resulting in a substantial burden of approximately 5 billion U.S. dollars in hospitalization costs,” the researchers stated.

“Modifiable factors associated with CAP such as tobacco smoking and immunizations should be health interventions to prevent the burden of CAP in COPD patients,” even though “pneumococcal vaccination was used more often in the COPD population than in other CAP patients, but pneumococcal pneumonia still occurred at a numerically higher rate,” they noted.

The study was supported by the University of Louisville, Ky., with partial support from Pfizer. The authors reported having no conflicts.

For primary care patients with acute exacerbations of chronic obstructive pulmonary disease (COPD), point-of-care C-reactive protein testing reduced antibiotic use with no evidence of harm, according to a recent randomized, controlled trial.

Point-of-care C-reactive protein (CRP) testing led to fewer antibiotic prescriptions at the initial consultation, according to investigators participating in the PACE study, a multicenter, open-label trial of more than 600 patients with COPD enrolled at one of 86 general practices in the United Kingdom.

Patient-reported antibiotic use over the next 4 weeks was more than 20 percentage points lower for the group managed with the point-of-care strategy, compared with those who received usual care, according to the investigators, led by Christopher C. Butler, FMedSci, of the Nuffield Department of Primary Care Health Sciences at the University of Oxford (England).

Less antibiotic use and fewer prescriptions did not compromise patient-reported, disease-specific quality of life, added Dr. Butler and colleagues. Their report appears in the New England Journal of Medicine.

In the United States and in Europe, more than 80% of COPD patients with acute exacerbations will receive an antibiotic prescription, according to Dr. Butler and coauthors.

“Although many patients who have acute exacerbations of COPD are helped by these treatments, others are not,” wrote the investigators, noting that in one hospital-based study, about one in five such exacerbations were thought to be due to noninfectious causes.

The present study included patients at least 40 years of age who presented to a primary care practice with an acute exacerbation and at least one of the three Anthonisen criteria (increased dyspnea, sputum production, and sputum purulence) intended to guide antibiotic therapy in COPD. A total of 325 were randomly assigned to the CRP testing group, and 324 to a group that received just usual care.

Antibiotic use was reported by fewer patients in the CRP testing group, compared with the usual-care group (57.0% vs. 77.4%; adjusted odds ratio, 0.31, 95% confidence interval, 0.20-0.47), the investigators reported.

Only 47.7% of patients in the CRP-guided group received antibiotic prescriptions at the initial consultation, vs. 69.7% of patients in the usual care group.

Hospitalizations over 6 months of follow-up were reported for 8.6% and 9.3% of patients in the CRP-guided and usual-care groups, respectively, while diagnoses of pneumonia were recorded for 3.0% and 4.0%. There was no clinically important difference between groups in the rate of antibiotic-related adverse effects.

“The evidence from our trial suggests that CRP-guided antibiotic prescribing for COPD exacerbations in primary care clinics may reduce patient-reported use of antibiotics and the prescribing of antibiotics by clinicians,” Dr. Butler and colleagues said in a discussion of these results.

Findings from the study by Dr. Butler and colleagues are “compelling enough” to support C-reactive protein (CRP) testing to guide antibiotic use in patient who have acute exacerbations of COPD, wrote the authors of an accompanying editorial.

“The trial achieved its objective, which was to show that CRP testing safely reduces antibiotic use,” stated Allan S. Brett, MD, and Majdi N. Al-Hasan, MB,BS, of the department of medicine at the University of South Carolina, Columbia.

Point-of-care testing of CRP could be applied even more broadly in clinical practice, Dr. Brett and Dr. Al-Hasan wrote, since testing has been shown to reduce prescribing of antibiotics for suspected lower respiratory tract infections and other common presentations in patients with no COPD.

“Whether primary care practices in the United States would embrace point-of-care CRP testing is another matter, given the regulatory requirements for in-office laboratory testing and uncertainty about reimbursement,” they noted.

Reduced antibiotic prescribing in patients with COPD likely has certain benefits, including reducing risk of Clostridioides difficile colitis, according to the authors.

By contrast, the current study did not determine which COPD patients might benefit from antibiotics, if any, nor which antibiotic might be warranted for those patients.

The study was supported by the Health Technology Assessment Program of the UK National Institute for Health Research. Dr. Butler reported disclosures related to Roche Molecular Systems and Roche Molecular Diagnostics, among others.

Butler, FMedSci, of the Nuffield Department of Primary Care Health Sciences at the University of Oxford (England).

Less antibiotic use and fewer prescriptions did not compromise patient-reported, disease-specific quality of life, added Dr. Butler and colleagues. Their report appears in the New England Journal of Medicine.

In the United States and in Europe, more than 80% of COPD patients with acute exacerbations will receive an antibiotic prescription, according to Dr. Butler and coauthors.

“Although many patients who have acute exacerbations of COPD are helped by these treatments, others are not,” wrote the investigators, noting that in one hospital-based study, about one in five such exacerbations were thought to be due to noninfectious causes.

The present study included patients at least 40 years of age who presented to a primary care practice with an acute exacerbation and at least one of the three Anthonisen criteria (increased dyspnea, sputum production, and sputum purulence) intended to guide antibiotic therapy in COPD. A total of 325 were randomly assigned to the CRP testing group, and 324 to a group that received just usual care.

Antibiotic use was reported by fewer patients in the CRP testing group, compared with the usual-care group (57.0% vs. 77.4%; adjusted odds ratio, 0.31, 95% confidence interval, 0.20-0.47), the investigators reported.

Only 47.7% of patients in the CRP-guided group received antibiotic prescriptions at the initial consultation, vs. 69.7% of patients in the usual care group.

Hospitalizations over 6 months of follow-up were reported for 8.6% and 9.3% of patients in the CRP-guided and usual-care groups, respectively, while diagnoses of pneumonia were recorded for 3.0% and 4.0%. There was no clinically important difference between groups in the rate of antibiotic-related adverse effects.

“The evidence from our trial suggests that CRP-guided antibiotic prescribing for COPD exacerbations in primary care clinics may reduce patient-reported use of antibiotics and the prescribing of antibiotics by clinicians,” Dr. Butler and colleagues said in a discussion of these results.

Findings from the study by Dr. Butler and colleagues are “compelling enough” to support C-reactive protein (CRP) testing to guide antibiotic use in patient who have acute exacerbations of COPD, wrote the authors of an accompanying editorial.

“The trial achieved its objective, which was to show that CRP testing safely reduces antibiotic use,” stated Allan S. Brett, MD, and Majdi N. Al-Hasan, MB,BS, of the department of medicine at the University of South Carolina, Columbia.

Point-of-care testing of CRP could be applied even more broadly in clinical practice, Dr. Brett and Dr. Al-Hasan wrote, since testing has been shown to reduce prescribing of antibiotics for suspected lower respiratory tract infections and other common presentations in patients with no COPD.

“Whether primary care practices in the United States would embrace point-of-care CRP testing is another matter, given the regulatory requirements for in-office laboratory testing and uncertainty about reimbursement,” they noted.

Reduced antibiotic prescribing in patients with COPD likely has certain benefits, including reducing risk of Clostridioides difficile colitis, according to the authors.

By contrast, the current study did not determine which COPD patients might benefit from antibiotics, if any, nor which antibiotic might be warranted for those patients.

The study was supported by the Health Technology Assessment Program of the UK National Institute for Health Research. Dr. Butler reported disclosures related to Roche Molecular Systems and Roche Molecular Diagnostics, among others.

For primary care patients with acute exacerbations of chronic obstructive pulmonary disease (COPD), point-of-care C-reactive protein testing reduced antibiotic use with no evidence of harm, according to a recent randomized, controlled trial.

Point-of-care C-reactive protein (CRP) testing led to fewer antibiotic prescriptions at the initial consultation, according to investigators participating in the PACE study, a multicenter, open-label trial of more than 600 patients with COPD enrolled at one of 86 general practices in the United Kingdom.

Among Medicare patients with chronic obstructive pulmonary disease (COPD), those who had at least one exacerbation and had a COPD-related hospitalization were most likely to receive nebulized arformoterol, according to study to identify predictors of its use. In addition to being sicker, being treated by a pulmonologist rather than a primary care physician and being white were factors that increased a patient’s likelihood of receiving nebulized arformoterol.

Patients less likely to receive the nebulized version of this long-acting beta2 adrenoreceptor agonist (LABA) were African Americans, patients with psychiatric comorbidities, and patients eligible for both Medicare and Medicaid.

“Studies have shown that 40% to 71% of Medicare beneficiaries receive no maintenance treatment for COPD. Although a recent longitudinal study on Medicare populations reported that use of maintenance medications has been improving, in general, it is recognized that Medicare beneficiaries with COPD remain undertreated,” Todd P. Gilmer, PhD, from the department of family medicine and public health at the University of California, San Diego, and colleagues wrote.

The investigators identified patients with COPD using Medicare administrative data; of these patients, 11,887 were arformoterol users, and 450,178 were control patients who did not use arformoterol. Patients were included in the study if they had at least one claim for COPD medication and were continuously enrolled in Medicare Parts A, B, and D. The cohort consisted of mostly white women aged 70 years or older, and 47% were dual-eligible to receive both Medicare and Medicaid benefits. A subgroup of 1,778 arformoterol users were also identified for analysis who were hospitalized and discharged within 30 days of using arformoterol, as well as a subgroup of 21,910 control patients with hospitalizations.

The researchers found COPD-related hospitalization (odds ratio, 1.31; 95% confidence interval, 1.24-1.39; P less than .001), exacerbation (OR, 1.33; 95% CI, 1.26-1.41; P less than .001), use of a systemic corticosteroid (OR, 1.50; 95% CI, 1.43-1.57; P less than .001) or methylxanthine (OR, 1.37; 95% CI, 1.28-1.47; P less than .001), use of oxygen therapy (OR, 2.01; 95% CI, 1.93-2.09; P less than .001), pulmonologist care (OR, 1.40; 95% CI, 1.34-1.46; P less than .001), and respiratory therapist care (OR, 1.23; 95% CI, 1.11-1.36; P less than .001) strongly predicted arformoterol use, while racial/ethnic minority status, psychiatric comorbidity (OR, 0.65; 95% CI, 0.56-0.76; P less than .001), acquired immune deficiency syndrome (OR, 0.69; 95% CI, 0.52-0.94; P less than .01), and dual-eligibility for Medicare and Medicaid (OR, 0.73; 95% CI, 0.70-0.77; P less than .001) lowered the odds of arformoterol use (P less than .001). In the subgroup of patients with hospitalizations, COPD-related admission (OR, 1.83; 95% CI, 1.55-2.14; P less than .001), exacerbation (OR, 2.62; 95% CI, 1.88-3.63; P less than .001)m and inpatient care from a pulmonologist (OR, 1.78; 95% CI, 1.58-2.01; P less than .001) predicted arformoterol use.

“Given the results of this study, increasing access to nebulized maintenance therapy is warranted for select populations with COPD including racial/ethnic minorities, the dual-eligible, and those with certain comorbidities, such as psychiatric disorders,” Dr. Gilmer and colleagues wrote in their study. “Future studies are needed to explore the optimal time to initiate nebulized maintenance therapy, and the potential differential impact of early versus late initiation on patient outcomes.”

Researchers noted that, although their results may seem initially counterintuitive given that COPD has a higher prevalence in men, 56% of the beneficiaries in their Medicare data were women who were 65 years or older, and the results are consistent with other studies that show similar gender distribution findings for maintenance treatment patterns among COPD patients receiving Medicare.

“Since most Medicare beneficiaries with COPD are older than 70 years of age, the higher percentage of women than men in our two cohorts can be explained by the age distributions that ensued as a result of applying our various inclusion and exclusion criteria,” they said.

Acute exacerbations in chronic obstructive pulmonary disease could also trigger a cardiac event such as MI or stroke, particularly in older individuals, new research has found.

In Respirology, researchers report the outcomes of a nationwide, register-based study involving 118,807 patients with chronic obstructive pulmonary disease (COPD) who experienced a major adverse cardiac event after an exacerbation.

They found that the risk of any major cardiac adverse event increased 270% in the 4 weeks after the onset of an exacerbation (95% confidence interval, 3.60-3.80). The strongest association was seen for cardiovascular death, for which there was a 333% increase in risk, but there was also a 257% increase in the risk of acute MI and 178% increase in the risk of stroke.

The risk of major adverse cardiac events was even higher among individuals who were hospitalized because of their COPD exacerbation (odds ratio, 5.92), compared with a 150% increase in risk among those who weren’t hospitalized but were treated with oral corticosteroids and 108% increase among those treated with amoxicillin with enzyme inhibitors.

The risk of a major cardiac event after a COPD exacerbation also increased with age. Among individuals younger than 55 years, there was a 131% increase in risk, but among those aged 55-69 years there was a 234% increase, among those aged 70-79 years the risk increased 282%, and among those aged 80 years and older it increased 318%.

Mette Reilev, from the department of public health at the University of Southern Denmark, Odense, and coauthors suggested that acute exacerbations were associated with elevated levels of systemic inflammatory markers such as fibrinogen and interleukin-6, which were potently prothrombotic and could potentially trigger cardiovascular events.

“Additionally, exacerbations may trigger type II myocardial infarctions secondary to an imbalance in oxygen supply and demand,” they wrote.

The authors raised the question of whether cardiovascular prevention strategies should be part of treatment recommendations for people with COPD, and suggested that prevention of COPD exacerbations could be justified even on cardiovascular grounds alone.

“Studies investigating the effect of cardiovascular treatment on the course of disease among COPD exacerbators are extremely scarce,” they wrote. “Thus, it is currently unknown how to optimize treatment and mitigate the increased risk of [major adverse cardiovascular events] following the onset of exacerbations.”

However, they noted that prednisolone treatment for more severe exacerbations may have a confounding effect, as oral corticosteroids could induce dyslipidemia, hypertension, and hyperglycemia, and increase long-term cardiovascular risk.

Six authors declared funding from the pharmaceutical industry – three of which were institutional support – unrelated to the study.

The ratio of the forced expiratory volume in 1 second to the forced vital capacity (FEV₁:FVC) at the recommended threshold of 0.70 effectively diagnosed individuals at risk for clinically significant COPD, a longitudinal study of more than 24,000 individuals has found.

Guidelines from respiratory societies have long recommended a diagnosis of airflow obstruction when the FEV₁:FVC is less than 0.70, but no rigorous, population-based studies have been conducted to support this recommendation, wrote Surya P.

“The selection of a threshold for defining airflow obstruction has major implications for patient care and public health as the prevalence of airflow obstruction can vary by as much as 33% depending on which threshold is selected,” they said.

In a study published in JAMA, the researchers reviewed data from 24,207 participants in the National Heart, Lung, and Blood Institute Pooled Cohorts Study to assess the accuracy of different thresholds in predicting COPD events in a large, multiethnic, U.S. population. All participants underwent spirometry; the average age at spirometry was 63 years, and 54% of the patients were women. Patients were enrolled during 1987-2000 and received follow-up longitudinally through 2016.

Overall, 3,925 participants experienced COPD-related events during an average of 15 years of follow-up (more than 340,757 person-years). These events included 3,563 hospitalizations and 447 deaths related to COPD.

The researchers compared three thresholds for FEV₁:FVC ratios: a fixed optimal threshold of 0.71, a lower limit of normal (LLN) defined as 0.034, and the currently recommended 0.70.

The optimal 0.71 was not significantly different from the recommended 0.70 but was significantly more accurate than the LLN of 0.034. In addition, the 0.70 value was the optimal predictor in a subgroup analysis of ever-smokers and in multivariate analysis.

The findings were limited by several factors including the use of prebronchodilator spirometry, lack of adjustment for medication use, and limitation of outcomes to COPD mortality or clinical events mainly caused by COPD, which might exclude patients with mild to moderate disease, the researchers noted.

However, the study “provides population-based evidence to support 0.70 as the optimal FEV₁:FVC threshold for defining clinically significant airflow obstruction,” to help clinicians identify patients at increased risk for significant COPD, they said.

The ratio of the forced expiratory volume in 1 second to the forced vital capacity (FEV₁:FVC) at the recommended threshold of 0.70 effectively diagnosed individuals at risk for clinically significant COPD, a longitudinal study of more than 24,000 individuals has found.

Guidelines from respiratory societies have long recommended a diagnosis of airflow obstruction when the FEV₁:FVC is less than 0.70, but no rigorous, population-based studies have been conducted to support this recommendation, wrote Surya P.

Use of inhaled corticosteroids may lower the risk of lung cancer in patients with chronic obstructive pulmonary disease, and continued use may also reduce lung cancer risk, recent research from the European Respiratory Journal has shown.

“The appropriate use of [inhaled corticosteroids] ICS in [chronic obstructive pulmonary disease] COPD patients is often debated and not all patients might benefit from the use of ICS. The clinical benefits and risk of use in an individual patient must be weighed by the physician,” wrote Adam J.N. Raymakers, MSc, PhD, of the University of British Columbia’s Collaboration for Outcomes Research and Evaluation (CORE), Vancouver, B.C., and colleagues.

“This study, however, indicates that potential benefits may accrue from ICS use in COPD patients in terms of reduced lung cancer risk, and that sustained use may be associated with reduced risk of lung cancer.”

Dr. Raymakers and colleagues did an analysis of 39,676 patients with COPD (mean age, 70.7 years; 53% female) who received ICS between 1997 and 2007 and linked those patients to a registry of cancer patients in British Columbia. The linked databases included the Medical Services Plan (MSP) payment information file, Discharge Abstract Database (DAD), PharmaNet data file, and the British Columbia Cancer Registry (BCCR). The researchers determined a patient had COPD if he or she received three or more prescriptions related to COPD, while ICS exposure was analyzed in the context of a patient’s ICS exposure, cumulative duration, cumulative dose, and weighted cumulative duration and dose.

The analysis revealed 372,075 prescriptions for ICS were dispensed and 71.2% of the patients were “distinct users” of ICS, with patients filling a median of eight prescriptions at mean 5.2 years of follow-up. Fluticasone propionate was the most common ICS prescribed at a dose of 0.64 mg per day, and patients had median 60 days of ICS supplied per person.

Overall, there were 994 cases of lung cancer (2.5%), and exposure to ICS was linked to a 30% reduction in lung cancer risk (hazard ratio, 0.70; 95% confidence interval, 0.61-0.80), while recency-weighted duration of ICS exposure was linked to a 26% reduction in lung cancer risk (HR, 0.74; 95% CI, 0.66-0.87). There was a 43% reduced risk of lung cancer per gram of ICS when the data were measured by recency-weighted cumulative dosage.

In a multivariate analysis, ICS use was associated with a 30% reduction in risk of non–small cell lung cancer (HR, 0.70; 95% CI, 0.60-0.82), which the researchers said suggests ICS provides a protective effect for patients against lung cancer. “These results highlight the importance of properly identifying which patients might be at the highest risk of lung cancer, to enhance the therapeutic benefits of ICS in these COPD patients,” they wrote.

This study received funding from the Canadian Institutes of Health Research. The authors report no conflicts of interest.

Chronic obstructive pulmonary disease (COPD) prevalence among adults is strongly correlated with their state’s current smoking prevalence, according to a Centers for Disease Control and Prevention analysis of respondents to a behavioral risk factor survey.

“Population-based strategies for smoking prevention and control have the potential to decrease the prevalence of COPD in the United States,” wrote Anne G. Wheaton, PhD, of the CDC’s National Center for Chronic Disease Prevention and Health Promotion and coauthors. The study was published in the Morbidity and Mortality Weekly Report.

Dr. Wheaton and her fellow researchers analyzed data from 418,378 adult respondents to the 2017 Behavioral Risk Factor Surveillance System survey. Responses came from all 50 states and Washington, D.C.; respondents who had smoked less than 100 lifetime cigarettes were categorized as “never smoked,” while those who had smoked at least 100 cigarettes but no longer smoked were categorized as “former smokers.” Anyone who had smoked at least 100 cigarettes and currently smoked was categorized as a “current smoker.”

The age-adjusted prevalence of COPD among U.S. adults was 6.2% (95% confidence interval, 6.0%-6.3%) in 2017. Current cigarette smokers had a prevalence of 15.2% (95% CI, 14.7%-15.7%); this dipped to 7.6% (95% CI, 7.3%-8.0%) among former smokers and 2.8% (95% CI, 2.7%-2.9%) among adults who had never smoked. Patterns were visible within states: Current smokers had a state-level prevalence of COPD that was strongly correlated with state-level current smoking prevalence (Pearson correlation coefficient, 0.69; P less than .001). State-level COPD prevalence among former smokers (Pearson correlation coefficient, 0.71; P less than .001) and those who never smoked (Pearson correlation coefficient, 0.64; P less than .001) were also strongly correlated with the current smoking prevalence, indicating secondhand smoke as a risk factor for COPD.

The coauthors acknowledged the study’s limitations, including relying on self-reporting for both COPD and smoking status. They also noted that there was no way to measure exposure to secondhand smoke, other indoor or outdoor air pollutants, or respiratory infection history, “all of which might contribute to COPD risk.”

No conflicts of interest were reported.

SAN ANTONIO – People who smoke and have opioid use disorder have a lower likelihood of drug use several months after initiating smoking cessation treatment if they are treated with nicotine replacement therapy rather than varenicline, new research suggests.

“Differences were not due to the pretreatment differences in drug use, which were covaried,” wrote Damaris J. Rohsenow, PhD, and colleagues at Brown University’s Center for Alcohol and Addiction Studies, Providence, R.I. “Results suggest it may be preferable to offer smokers with opioid use disorder [nicotine replacement therapy] rather than varenicline, given their lower adherence and more illicit drug use days during follow-up when given varenicline compared to [nicotine replacement therapy].”

They shared their research poster at the annual meeting of the College on Problems of Drug Dependence.

About 80%-90% of patients with OUD smoke, and those patients have a particularly difficult time with smoking cessation partly because of nonadherence to cessation medications, the authors noted. Smoking increases the risk of relapse from any substance use disorder, and pain – frequently comorbid with smoking – contributes to opioid use, they added.

Though smoking treatment has been shown not to increase drug or alcohol use, varenicline and nicotine replacement therapy have different effects on a4b2 nicotinic acetylcholinergic receptors (nAChRs). The authors noted that nicotine offers greater pain inhibition via full agonist effects across multiple nAChRs, whereas varenicline has only a partial agonist effect on a single nAChR.

“Smokers may receive more rewarding dopamine effects from the full nicotine agonist,” they wrote. The researchers therefore aimed to compare responses to nicotine replacement therapy and varenicline among smokers with and without OUD.

Ninety patients without OUD and 47 patients with it were randomly assigned to receive transdermal nicotine replacement therapy with placebo capsules or varenicline capsules with a placebo patch for 12 weeks with 3- and 6-month follow-ups. At baseline, those with OUD were significantly more likely to be white and slightly younger and have twice as many drug use days than those without the disorder.

Differences also existed between those with and without OUD for comorbid alcohol use disorder (55% vs. 81%), marijuana use disorder (32% vs. 19%) and cocaine use disorder (70% vs. 55%).

Those without OUD had slightly greater medication adherence, but with only borderline significance just among those taking varenicline. Loss to follow-up, meanwhile, was significantly greater for those with OUD in both treatment groups.

Most striking was the significantly higher number of drug use days among those with OUD who took varenicline vs. all other groups. Those patients had 16.5 drug use days at 4-6 months’ follow-up, compared with 0.13 days among those with OUD using nicotine replacement therapy (P less than .026). Among those without OUD, nicotine replacement therapy patients had 5 drug use days, and varenicline patients had 2.5 drug use days.

“Given interactions between nicotine and the opioid system and given that [nicotine replacement therapy] binds to more types of nAChRs than varenicline does, it is possible that [nicotine replacement therapy] dampens desire to use opiates compared to varenicline by stimulating more nAChRs,” the authors wrote. “Increasing nicotine dose may be better for smokers with opioid use disorder,” they added, though they noted the small size of the study and the need for replication with larger populations.

The research was funded by the National Institute on Drug Abuse and the Department of Veterans Affairs. The authors reported no disclosures.

Most striking was the significantly higher number of drug use days among those with OUD who took varenicline vs. all other groups. Those patients had 16.5 drug use days at 4-6 months’ follow-up, compared with 0.13 days among those with OUD using nicotine replacement therapy (P less than .026). Among those without OUD, nicotine replacement therapy patients had 5 drug use days, and varenicline patients had 2.5 drug use days.

“Given interactions between nicotine and the opioid system and given that [nicotine replacement therapy] binds to more types of nAChRs than varenicline does, it is possible that [nicotine replacement therapy] dampens desire to use opiates compared to varenicline by stimulating more nAChRs,” the authors wrote. “Increasing nicotine dose may be better for smokers with opioid use disorder,” they added, though they noted the small size of the study and the need for replication with larger populations.

The research was funded by the National Institute on Drug Abuse and the Department of Veterans Affairs. The authors reported no disclosures.
