Background and Aims: We investigated feasibility and value of a real‐time electronic monitoring system adapted for early detection of cystic fibrosis (CF) pulmonary exacerbations (P Exs). Methods: This was a 6‐month prospective study. Patients recorded once daily their symptom score and spirometry using an electronic diary. The data were sent daily to the research team in real time. P Ex was considered to be present when change in symptoms and lung function values met a preset criteria. Number of P Exs during the study was compared with a parallel period of the previous and of the following years. Results: Only 19 patients (37.2%) completed recording that could be evaluated. A total of 53 P Exs were identified, 26 (49.0%) of which needed intravenous (IV) antibiotics. The number of total P Exs in the study year did not differ from the previous or the following year, but the number of courses of oral antibiotics was greater than those given during the previous year. Conclusion: Remote daily monitoring of symptoms and spirometry had a poor uptake among CF patients. For those who completed the study, this method early detected P Exs that were treated with oral antibiotics that might otherwise required IV antibiotics.

The effects of a pulmonary rehabilitation program on 44 patients with chronic obstructive pulmonary disease (COPD) were compared to a control group. The treated group was admitted to the program for a period of three months. The program consisted of several parts, such as physical training, health education, and psychological and social matters. Before participation, the patients were thoroughly examined and provided with optimal medical treatment. Both groups were assessed by means of biometrical tests and questionnaires for a period of 2 years. The rehabilitation group improved significantly in endurance, psychological parameters, and consumption of medical care. Working days increased and their way of life became more active. Smoking habits and body fat percentage decreased. Bronchial hyperreactivity, need for pulmonary drugs, and coughing and sputum production did not improve in the rehabilitation group compared to the control group. Airway obstruction, expressed as forced expiratory volume in one second, and complaints of dyspnea, allergy and hyperreactivity scores on questionnaires improved only in the short term (<1 year), but did not improve significantly in the long term. This study shows that pulmonary rehabilitation can result in improvements in patients with asthma or COPD who have many complaints despite the fact that their pulmonary function is not severely disturbed. 相似文献

The objective of this 1-week cross-sectional survey was to assess the clinical features of outpatients with chronic obstructive pulmonary disease (COPD). A one-page questionnaire was used to collect demographic data, smoking status, and COPD-related variables. Ten or 20 consecutive patients were selected from Primary care or specialised setting during a week. Pulmonary function (FEV1) was measured using an electronic device (Piko-1). The study sample comprised 11,973 COPD patients (83% men) with a mean (sd) age of 67 (10.7) years. Thirty-five percent of patients were current smokers and smoked a mean of 17.4 (9.9) cigarettes daily. COPD severity according to GOLD stages was mild in 20% of patients, moderate in 38%, severe in 30%, and very severe in 12%. A higher percentage of men showed severe (33%) or very severe (14%) disease compared to women (16% and 6%, respectively) (P<0.005). Forty-two percent of patients had severe functional impairment and 35% continued smoking. Moreover, 11% of patients with very severe COPD smoked more than 20 cigarettes a day. The mean frequency of visits in the previous year was every 4.6 (4.1) months, with cough as the main reason for consultation. The most commonly used drugs were long-acting beta2-agonists (78%) and inhaled steroids (77%). Inhaled steroids were used by 84% of patients with very severe, 82% with severe disease, 73% with moderate disease, and 69% with mild disease (chi2 for trend, P<0.0001). This survey carried out in a real life setting shows that 42% of the patients who completed the questionnaire had severe COPD, 35% of them continued smoking, and 69% of patients with mild COPD used inhaled steroids. 相似文献

Background Known inflammatory markers have limited sensitivity and specificity to differentiate viral respiratory tract infections from other causes of acute exacerbation of COPD (AECOPD). To overcome this, we developed a multi‐factorial prediction model combining viral symptoms with inflammatory markers.
Methods Interleukin‐6 (IL‐6), serum amyloid A (SAA) and viral symptoms were measured in stable COPD and at AECOPD onset and compared with the viral detection rates on multiplex PCR. The predictive accuracy of each measure was assessed using logistic regression and receiver operating characteristics curve (ROC) analysis.
Results There was a total of 33 viruses detected at the onset of 148 AECOPD, the majority 26 (79%) were picornavirus. Viral symptoms with the highest predictive values were rhinorrhoea [Odds ratio (OR) 4·52; 95% CI 1·99–10·29; P < 0·001] and sore throat (OR 2·64; 95% CI 1·14–6·08; P = 0·022), combined the AUC ROC curve was 0·67. At AECOPD onset patients experienced a 1·6‐fold increase in IL‐6 (P = 0·008) and 4·5‐fold increase in SAA (P < 0·001). The addition of IL‐6 to the above model significantly improved diagnostic accuracy compared with symptoms alone (AUC ROC 0·80 (P = 0·012).
Conclusion The addition of inflammatory markers increases the specificity of a clinical case definition for viral infection, particularly picornavirus infection. 相似文献

Background and objective
Chronic obstructive pulmonary disease (COPD) represents an increasing healthcare concern as a leading cause of morbidity and mortality worldwide. Our objective was to predict the outcome of COPD patients associated with multiple organ dysfunction syndrome (MODS) by scoring models.Methods
A retrospective study was performed on severe COPD patients within 24 hours of the onset of MODS. The Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE III, Multiple Organ Dysfunction Score (MODS), Simplified Acute Physiology Score II (SAPS II), and Sepsis-related Organ Failure Assessment (SOFA) scores were calculated for patients.Results
A total of 153 elderly patients were recruited. Compared to 30-day survivors, the number of failing organs and all of the scoring models were significantly higher in 30-day non-survivors. The SOFA showed the highest sensitivity and area under the curve (AUC) for predicting the prognosis of patients with MODS induced by acute exacerbation of COPD. The results of logistic regression indicated that factors that were correlated with the prognosis of COPD included the exacerbation history, SOFA score, number of failing organs, and duration of ICU stay. The value of exacerbation frequency for predicting the outcome of COPD was excellent (AUC: 0.892), with a sensitivity of 0.851 and a specificity of 0.797.Conclusions
The SOFA score, determined at the onset of MODS in elderly patients with COPD, was a reliable predictor of the prognosis. The exacerbation frequency, number of failing organs, and the SOFA score were risk factors of a poor prognosis, and the exacerbation frequency could also effectively predict the outcome of COPD. 相似文献13.
BACKGROUND: There has been no direct comparison between an incremental and endurance walking test to detect the relative oxygen desaturation in patients with chronic obstructive pulmonary disease (COPD). This is of some importance as current guidelines have suggested that ambulatory oxygen should only be prescribed after a standard assessment and desaturation documented. No clear advice about the nature of the required exercise task is given. This study therefore compared the relative desaturation between the incremental shuttle walking test (ISWT) and the constant speed walking test (ESWT) and response to ambulatory oxygen. METHODS: Forty-one patients (29 male), mean (SD), age 71.18 (7.48) yrs, FEV(1) 0.85 (0.29) l with stable COPD were recruited after completion of a 7-week pulmonary rehabilitation programme. Patients completed a baseline (without carrying a cylinder) ISWT and ESWT and then, in random order in double blind fashion, completed the walk tests with a cylinder of air or a cylinder of oxygen. Measurements included distance walked, oxygen saturation, heart rate, perceived breathlessness and exertion (Borg scale). RESULTS: All patients desaturated (<4% below 90%). There was no significant difference in desaturation between the ISWT and the ESWT. There was a significant improvement in performance with supplementary oxygen compared to cylinder air (p<0.05) for both tests. However, compared to the baseline walk, supplementary oxygen did not enhance the distance walked for either test. There was a significant decrease in walking performance on both the ISWT and the ESWT when carrying an air cylinder compared with the control walk. When comparing the percentage difference between oxygen and air for responders (i.e. those that achieve a 10% or more increase), the ESWT showed a greater percentage change 42.1% compared to 26.1% for the ISWT. CONCLUSIONS: This study identifies that incremental and endurance walking provokes significant desaturation and that there is a short-term benefit of oxygen versus air in enhancing exercise performance. There was no significant difference in the level of desaturation between tests. Therefore the ISWT is a suitable exercise test that can be used to evaluate desaturation and is practically more realistic. 相似文献

Background
Poor adherence leads to a high rate of exacerbation and poor health-related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD). However, few strategies are acceptable and effective in improving medication adherence. We investigated whether pharmaceutical care by clinical pharmacists could reinforce medication adherence to reduce exacerbation and improve HRQoL.Methods
A randomized controlled study was carried out at The First Affiliated Hospital of Guangzhou Medical University from February 2012 to January 2014. Non-adherence patients were randomly assigned to receive pharmaceutical care or to usual care. The pharmaceutical care consisted of individualized education and a series of telephone counseling for 6 months provided by clinical pharmacists. Medication adherence was measured by pill counts plus direct interview at 1- and 6-month pharmaceutical care and one-year follow-up. Severe exacerbations were defined as events that led to hospitalization for acute COPD attack. An interview was conducted to investigate hospital admissions and evaluate severe exacerbations at one-year follow-up. HRQoL was measured by St George’s Respiratory Questionnaire at 6 months.Results
At 6-month pharmaceutical care and one-year follow-up, the pharmaceutical care group exhibited higher medication adherence than the usual care group (73.4±11.1 vs. 55.7±11.9, P=0.016 and 54.4±12.5 vs. 66.5±8.6, P=0.039, respectively). There are 60 acute exacerbations resulted in a hospital admission in the usual group while 37 ones in the pharmaceutical care group during one-year follow-up (P=0.01). Hospital admissions due to acute exacerbation in the pharmaceutical care group were 56.3% less than the usual care group (P=0.01). There was a significant difference in the symptoms and impact subscales respectively at 6-month pharmaceutical care between two groups (P=0.032, P=0.018).Conclusions
Individualized pharmaceutical care improved medication adherence, reduced hospitalization and elevated HRQoL in patients with COPD. 相似文献17.

Background
In South Korea, chronic obstructive pulmonary disease (COPD) is one of the ten leading causes of death. COPD exacerbations are significantly associated with mortality in COPD patients. This study was conducted to investigate the epidemiology of COPD in South Korea, specifically the clinical characteristics of South Korean COPD patients, the COPD exacerbation rate and the risk factors associated with COPD exacerbations.Methods
This study covers a 2-year interval. One year was data collected retrospectively and the second year was prospectively obtained data.Results
A total of 1,114 subjects were enrolled in the study. These subjects were observed for a period of 1 year from the enrollment, and a total of 920 subjects completed the study. A total of 1,357 COPD exacerbations occurred in 711 subjects (63.8%) out of the total of 1,114 subjects during the study period of 2 years. Multivariate logistic regression results showed that if patients had had a pneumonia before the retrospective year of analysis, they had a 18 times greater chance of having an exacerbation during the prospective year when other variables were controlled. Also, the subjects who had a history of two or more exacerbations during the retrospective year were approximately 6 times more likely to experience the COPD exacerbation compared to those who did not.Conclusions
This study examined the demographic and clinical characteristics of South Korean COPD patients and found that a history of pneumonia and two or more occurrences of exacerbation within 1 year was significantly associated with a higher rate of COPD exacerbation. 相似文献19.

The standard respiratory function test for case detection of chronic obstructive pulmonary disease (COPD) is spirometry. The criterion for diagnosis defined in guidelines is based on the FEV1/FVC ratio forced expiratory ratio (FER) and its severity is based on forced expiratory volume in one second (FEV1) from measurements obtained during maximal forced expiratory manoeuvres. Spirometry is a safe and practical procedure, and when conducted by a trained operator using a spirometer that provides quality feedback, the majority of patients can be coached to provide acceptable and repeatable results. This allows potentially wide application of testing to improve recognition and diagnosis of COPD, such as for case finding in primary care. However, COPD remains substantially under diagnosed in primary care and a major reason for this is underuse of spirometry. The presence of symptoms is not a reliable indicator of disease and diagnosis is often delayed until more severe airflow obstruction is present. Early diagnosis is worthwhile, as it allows risk factors for COPD such as smoking to be addressed promptly and treatment optimised. Paradoxically, investigation of the patho-physiology in COPD has shown that extensive small airway disease exists before it is detectable with conventional spirometric indices, and methods to detect airway disease earlier using the flow-volume curve are discussed. 相似文献
