Narrative medicine educational project to improve the care of patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is characterised by a progressive loss of pulmonary function. Often patients do not adhere to inhaled therapies and this leads clinicians to switch treatments in order to improve control of the symptoms. Narrative medicine is a useful approach that helps healthcare professionals to think over the doctor-patient relationship and how patients live with their disease. The aim of this training project was to teach pulmonologists the basics of narrative medicine: to carefully listen to patients and to practice reflective writing in their relationship with them. Training on narrative medicine and parallel charts was provided through a webinar and a weekly newsletter. Across 362 narratives, written by 74 Italian pulmonologists, 92% of patients had activity limitations at their first visit. The main factor influencing the effectiveness and adherence to therapy was a positive doctor-patient relationship; indeed, if such relationship is difficult, only 21% of patients are able to resume all their activities. After learning the narrative approach, clinicians became aware of the need to spend more time listening to patients, to reflect through writing and to understand more deeply the motivations that lead people towards adherence to new therapies.

Tiotropium is less likely to induce oxygen desaturation in stable COPD patients compared to long-acting beta2-agonists.

In a three-way crossover pilot study, the acute effects of tiotropium 18 microg inhalation on the respiratory function and arterial blood gas tensions of 30 patients with stable chronic obstructive pulmonary disease (COPD) were compared with those of salmeterol 50 microg and formoterol 12 microg. In each study day, lung function and arterial blood gas analyses were performed before and up to 180 min after inhalation. All treatments significantly improved lung function, increased DLco, decreased PaO2, and increased P(A-a)O2, with no change in PaCO2. The effects of salmeterol and tiotropium on PaO2 were slower in onset and more prolonged than those of formoterol but PaO2AUC0-180 min was significantly greater for formoterol and salmeterol than for tiotropium. It is likely that the significant but small decreases in PaO2 and increases in P(A-a)O2 have been caused by pulmonary vasodilator effects. Since the three agents were similar in inducing bronchodilation, we believe that tiotropium is preferable in patients with hypoxemia caused by stable COPD because it seems to carry a smaller risk of worsening systemic hypoxemia.

Effect of formoterol, tiotropium, and their combination in patients with acute exacerbation of chronic obstructive pulmonary disease: a pilot study.

The aim of our study was to evaluate the pharmacodynamic effects of 1-day treatment with formoterol, tiotropium and their combination in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Twenty-one (19 males, mean age 72+/-8 years, mean FEV1 38+/-14% of predicted values) patients with mild to moderate AECOPD were enrolled. Patients received formoterol (12 microg deliver via Modulite b.i.d.), tiotropium (18 microg dry powder capsules delivered via HandiHaler once daily), and their combination, in randomized sequence. Serial measurements of FEV1, FVC, IC, SpO2 and HR were performed over 24h. Formoterol, tiotropium, and their combination significantly improved the area under curves (AUCs) for FEV1, FVC and IC over 12 and 24h. The mean FEV1, FVC and IC AUC(0-12h) and AUC(0-24h) after formoterol and tiotropium combination were significantly higher than formoterol and tiotropium alone, whereas the differences between the two single drugs were not statistically significant. Formoterol, either alone or in combination with tiotropium, elicited a significantly faster onset of action, and combination elicited a greater maximum bronchodilation than both single drugs in terms of FEV1 and FVC. After 24h the bronchodilating effect of the three treatments disappeared, with the exception of the combination on FEV1. The results of this study have documented that, although the time course of the effects of evaluated drugs differs significantly from that in stable COPD, with a shorter bronchodilation both for tiotropium and formoterol, these two long-acting bronchodilators appear to also be complementary in mild to moderate AECOPD.

Anxiety and depression in COPD patients: The roles of gender and disease severity.

BACKGROUND: The aim of our study was to assess the prevalence of anxiety and depression in the whole chronic obstructive pulmonary disease (COPD) population and in subgroups according to sex and severity classification. A secondary objective was to evaluate the possible differences between patients with and without a significant high level of anxiety, depression, or both, and finally to find out a correlation between psychological aspects, symptoms, functional parameters, and quality of life (QoL). METHODS: Two hundred and two COPD patients were enrolled. Their levels of anxiety, depression, dyspnea, and QoL were assessed using specific questionnaires. One hundred and fourteen sex- and age-matched healthy subjects were used as the control population. RESULTS: The prevalences of anxiety and depression were high (28.2% and 18.8%) in COPD even when it was of mild degree, compared to the control group, in which the prevalence of anxiety and depression were 6.1% and 3.5%, respectively. Female patients had higher levels of anxiety and depression and worse symptom-related QoL. Female patients reported a higher level of dyspnea than males for the same level of ventilatory impairment. Dyspnea was more strongly correlated with depression in women than in men. CONCLUSIONS: Anxiety and depressive symptoms are common in patients affected by COPD, even when their disease is mild in terms of FEV1 and respiratory symptoms. Female patients appear to be more exposed to psychological impairment, which correlates well with some specific symptomatic aspects of the disease, such as dyspnea. Psychological aspects need to be carefully assessed in COPD patients, particularly in females.

Close correlation between anxiety, depression, and asthma control.

BACKGROUND: We investigated the correlation between patients' characteristics, including anxiety and depression, and the level of asthma control evaluated by asthma control test (ACT), a self-administered validated questionnaire. METHODS: This is a cross-sectional study on asthmatic outpatients of three Italian hospitals. Demographic data, spirometry, anxiety and depression scores as well as the level of asthma control from 315 patients were collected. RESULTS: Patients with poorly controlled asthma were more frequently women, older, with a worse pulmonary function, obese, more anxious and/or more depressed. Four different independent factors associated with poor asthma control evaluated by ACT have been found: FEV(1)<60% (odds ratio, OR: 6.52), anxiety (OR: 3.76), age > or =65 years (OR: 2.69), and depression (OR: 2.45). The presence of anxiety and depression was associated with a higher healthcare utilization. Finally, we found a high level of agreement between ACT and multidimensional GINA approach in evaluating asthma control, with a concordance in 239 patients (81% of the population). CONCLUSION: There is a close correlation between anxiety and depression, and a poor asthma. A better understanding of this association may have major clinical implications, mainly in patients with poor controlled asthma in whom the presence of anxiety and depression should be investigated.

The pharmacodynamic effects of single inhaled doses of formoterol, tiotropium and their combination in patients with COPD.

The aim of this double-blind, double-dummy, cross-over, randomized, pilot study was to compare the acute bronchodilator efficacy of a single dose of formoterol with that of tiotropium in patients with stable chronic obstructive pulmonary disease (COPD). Because the potential of tiotropium for additive effects is yet unknown, the acute effects of adding this anticholinergic agent to formoterol were also explored. A total of 20 outpatients with stable COPD were enrolled. Single doses of 12 microg formoterol, 18 microg tiotropium, and 12 microg formoterol+18 microg tiotropium were given. Serial measurements of FEV1 were performed over 24 h. Formoterol, either alone or in combination with tiotropium, elicited a significantly faster onset of action and showed a trend for a greater maximum bronchodilation than tiotropium alone. At 24 h, mean FEV1 continued to be significantly higher than pre-dosing value following tiotropium and formoterol+tiotropium. These findings indicate that formoterol and tiotropium have different profiles that make both agents attractive alternatives in the treatment of stable COPD. Since tiotropium ensures prolonged bronchodilation, whereas formoterol adds fast onset and a greater peak effect, the two drugs appear complementary.
