Motivation and Confidence about Physical Activity in Chronic Obstructive Pulmonary Disease Patients: Health Benefits Matter to Patients.

INTRODUCTION: Physical activity (PA) has shown great benefits in patients with chronic obstructive pulmonary disease (COPD); however, their PA is below average. Motivational factors associated with PA in COPD have not been widely studied and could be a target for improving adherence to PA. The objective of our study was to identify and understand the different motivational and confidence factors related to low levels of PA in a COPD cohort. METHOD: Observational, prospective, multicenter study of COPD patients. Sociodemographic data, respiratory symptoms, comorbidities, spirometry, and exercise capacity were collected. PA was measured using the Dynaport accelerometer and patient motivation and confidence in PA were assessed by a questionnaire previously used in a COPD population in the USA. RESULTS: Eighty six COPD patients were included, 68.6% being male, with a mean (SD) age of 66.6 (8.5) years and a mean forced expiratory volume in the first second (%) of 50.9% (17.3%). The mean walking time was 82.8 (37.8) minutes/day. Questions related to health benefits and enjoying exercise were ranked highest in the motivation questionnaire and statistically significant differences were found in PA measures between patients with low and high motivation. A lack of confidence regarding hot weather and health-related issues significantly influenced PA levels. Advice from third parties, including healthcare providers, was not associated with higher PA levels. CONCLUSIONS: Improving the health of COPD patients is their main motivation to perform PA. Lack of confidence when it is hot or when they fear for their health is related to low levels of PA. Advice from third parties, including healthcare professionals, is not associated with higher PA. These results are relevant for developing strategies to increase the adherence of COPD patients to PA programs.

Personalised indication of augmentation therapy for emphysema associated with severe alpha-1 antitrypsin deficiency: a case series.

Severe alpha-1 antitrypsin deficiency (AATD) is associated with an increased risk of emphysema. However, the clinical manifestations are very heterogeneous, and an individual prognosis is very difficult to establish. Intravenous augmentation therapy with alpha-1 antitrypsin (AAT) from pooled blood donors is the only specific treatment available, but it requires weekly or biweekly administration for life. Several guidelines provide the indication criteria for the initiation of AAT augmentation therapy. However, in clinical practice, there are situations in which the decision as to when to start treatment becomes uncertain and some studies have shown great variability in the indication of this treatment even among specialists. The usual dilemma is between initiating augmentation therapy in individuals who may not develop significant lung disease or in whom disease will not progress or delaying it in patients who may otherwise rapidly and irreversibly progress. We illustrate this dilemma with five clinical cases: from the case of a patient with normal lung function who requests initiation of therapy to a moderately stable patient without augmentation or a mild patient who, after several years of remaining stable without treatment, deterioration in lung function initiated and, consequently, augmentation therapy was begun. All the nuances associated with the indication of augmentation justify a personalised approach and the decision about initiating augmentation therapy must be made after careful consideration of the pros and cons with the patient in reference centres with experience in treatment. These reference centres can work in collaboration with local hospitals where patients can be closely followed and augmentation therapy can be administered to avoid unnecessary travelling, making periodical administrations more comfortable for the patient.

Chronic Obstructive Lung Disease: Treatment Guidelines and Recommendations for Referral and Multidisciplinary Continuity of Care.

Chronic Obstructive Pulmonary Disease (COPD) constitutes a major public health problem, and it is anticipated that its prevalence will continue to increase in the future. Its progressive nature requires a continuous and well-coordinated care approach. The follow-up for COPD should primarily focus on disease screening and control, which includes monitoring of pulmonary function, prevention of exacerbations, identification of aggravating factors and comorbidities, as well as ensuring treatment adequacy and adherence. However, existing clinical practice guidelines and consensus documents offer limited recommendations for the follow-up. In this context, we undertake a review of COPD treatment and the continuity of care recommendations endorsed by several scientific societies. Moreover, we underscore the importance of the involvement of nursing and community pharmacy in this process, as well as the utilization of quality indicators in the provision of care for the disease.

Sex-Differences in Alpha-1 Antitrypsin Deficiency: Data From the EARCO Registry.

BACKGROUND: Sex and gender influence many aspects of chronic obstructive pulmonary disease (COPD). Limited data are available on this topic in alpha-1 antitrypsin deficiency (AATD). We therefore aimed to investigate sex issues in the EARCO registry, a prospective, international, observational cohort study. METHODS: Baseline data from PiZZ individuals, enrolled in the registry with complete data on sex and smoking history were analysed by group comparisons and binary logistic regression analyses. RESULTS: 1283 patients with AATD, 49.3% women were analysed. Females reported less tobacco consumption (16.8±12.2 vs. 19.6±14.5 PY, p=0.006), occupational exposures towards gases, dusts or asbestos (p<0.005 each) and consumed less alcohol (5.5±7.6 vs. 8.4±10.3u/week, p<0.001). Females reported COPD (41% vs. 57%, p<0.001) and liver disease (11% vs. 20%, p<0.001) less often. However, they had a higher prevalence of bronchiectasis (24% vs. 13%, p<0.001). Despite better lung function (FEV1%pred. 73.6±29.9 vs. 62.7±29.5, p<0.001) females reported a similar symptom burden (CAT 13.4±9.5 vs. 12.5±8.9, p=ns) and exacerbation frequency (at least one in the previous year 30% vs. 26%, p=ns) compared to males. In multivariate analyses, female sex was an independent risk factor for exacerbations in the previous year OR 1.6 p=0.001 in addition to smoking history, COPD, asthma and bronchiectasis and was also identified as risk factors for symptom burden (CAT≥10) OR 1.4 p=0.014 besides age, BMI, COPD and smoking history. CONCLUSION: Men had higher rates of COPD and liver disease, women were more likely to have bronchiectasis. Women's higher symptom burden and exacerbation frequency suggest they may need tailored treatment approaches.
