For a small proportion of patients with respiratory disorders, the regular medical care provided by general practitioners
and chest physicians does not result in control of respiratory symptoms.
In the Dutch Asthma Center, Davos, Switzerland, two conditions not available in routine medical settings are instrumental
in treating patients with severe respiratory illness. The treatment center is located at 1560 m above sea level in a high
altitude climate (low air humidity, low allergen concentration) which helps stabilize respiratory symptoms. Second, an interdisciplinary
treatment plan encompasses optimal medical care and psychological interventions (patient education, self-management training).
In this treatment facility, we carry out a cohort study on the determinants of the course of respiratory disorders in the
adult patients. At admission, at discharge, and at 6-month follow-up, patient are assessed on medical, psychological, and
medical outcome variables. At 6-month follow-up, 35% of the patients were readmitted to a hospital for exacerbations of respiratory
symptoms. Multivariate analyses point out that both pulmonary function and psychological factors (particularly state anxiety
and agoraphobia) predicted admission. Additional data will be presented and the implications for the multidisciplinary treatment
will be discussed. 相似文献

Objective: Ongoing airway inflammation measured by fractional exhaled nitric oxide (FENO) and airway hyperresponsiveness (AHR) to mannitol are associated in selected asthma patients, but no evidence exists of this association in unselected asthma patients. The aim was to investigate the association between FENO and AHR to mannitol in unselected individuals with possible asthma. Methods: A real-life study on patients with possible asthma referred to a specialized asthma clinic. Data on asthma history, FEV1, FENO, atopy, smoking, treatment and AHR to mannitol were collected. Results: In 217 unselected patients with symptoms suggestive of asthma, FENO and response to mannitol were tested. Of the 141 who underwent both tests, 32 (23%) had FENO >?25?ppb, and 58 (41%) had AHR to mannitol. A significant association between high FENO and AHR was found (p?0.001); 26% responded to mannitol despite a normal NO, and 8% had a high FENO but no AHR. Additionally, a weak association was found between log FENO and log response to mannitol (r?=?0.32, p?0.01). The area under the ROC curve for FENO as a predictor of AHR was 0.66 (95% CI 0.6–0.8) and for mannitol for having high FENO was 0.73 (95%CI 0.6–0.9). Conclusion: In a large sample of patients referred to an asthma clinic, an association was found between FENO and AHR to mannitol. However, a significant proportion of asthma patients had a normal FENO despite having AHR, suggesting that in some patients, AHR to mannitol is not driven by eosinophilic airway inflammation. 相似文献

Background
Mold sensitivity in asthmatic patients has recently attracted clinical interest; however the links between mold sensitivity and asthma severity in the Chinese population have been poorly characterized. In this study, we assess the relationship between asthma severity and airborne mold sensitivity in a cohort of northern Chinese patients.Methods
Ninety-three non-smoking adult outpatients with asthma completed a questionnaire and underwent skin prick testing with five aeroallergens. For all patients, eosinophil cell counts, total serum IgE (sIgE) levels, and pulmonary function were measured. An asthma severity score was calculated based on the patient’s forced expiratory volume in one second (FEV1), number of asthma attacks, number of hospital admissions, and use of inhaled or oral corticosteroids in the past year.Results
Ninety-three patients were divided into three groups based on the results of their allergy tests: negative results for all tested allergens (group A, n=32); positive reactions to aeroallergens including mold antigens (group B, n=41); and positive reactions to aeroallergens other than molds (group C, n=20). Patients in group B had a lower FEV1 (74.46%±23.09% predicted) compared with group A (85.52%±19.53%, P=0.023). Patients in both group B and C had elevated absolute eosinophil count (AEC) (group A: 3.12%±2.71%, group B: 5.41%±2.85%, group C: 6.1%±4.49%; group A vs. group B, P=0.008; group A vs. group C, P=0.002), and total sIgE values (group A: 117.36±144.90 IU/mL, group B: 195.86±155.87 IU/mL, group C: 253.31±152.41 IU/mL; group A vs. group B, P=0.031; group A vs. group C, P=0.002) compared with patients in group A. Asthma severity scores were higher in patients in group B compared to patients in group C (7 vs. 5.5, P<0.05). Patients allergic to molds were more likely to have severe asthma [odds ratio 3.636, 95% confidence interval (CI): 1.394 to 9.484; for severe versus mild asthma, P<0.05]. There was no association between asthma severity and sensitisation to house mites or weeds.Conclusions
Mold sensitivity is positively correlated with asthma severity in our cohort of northern Chinese patients. 相似文献6.

In order to ascertain the relative impact of coercion by a welfare program on retention in an ambulatory alcoholism program, records of 178 consecutive admissions to an inner-city alcoholism clinic were reviewed. Patients who came to the clinic via coerced referral from a public assistance agency were as likely to remain in treatment for at least nine sessions as self-referred patients. 相似文献

ObjectivesTo perform a third evaluation of therapeutic compliance in asthma patients managed in our department by using identical methodology to that employed in two prior evaluations (1995 and 1993). To study the possible association between correct inhalation technique and the patient's degree of knowledge about asthma.Material and methodsA random sample with a fixed rate was obtained, comprising 54 adult patients with asthma (aged more than 18 years old) managed in our department in an outpatient regime.Patients who reported that they habitually failed to comply with the treatment duration, the number of dosage times per day, or the dose at each specific dosage time were classified as noncompliers with the medication in question. The study was performed during October and November, 2003. First visits were excluded. The same categories of medications and procedures as those employed in the 1993 and 1995 studies were used.ResultsOf the 54 patients studied, 19 % revealed some type of pharmacological noncompliance. The overall percentage of incorrectly used medication was 8%. Among noncompliers, clinical course was poor in 44 % and additional visits to specialists or the emergency room were required in 45 %. Incorrect use was most frequent with the turbuhaler (32.1%), and faulty technique was also most common with this device (67.9 %).ConclusionsIn this evaluation, overall therapeutic compliance was clearly better than that in 1995 (81 % compared with 54 %), indicating a positive tendency over time. These results were more positive than those reported in the scientific literature on therapeutic compliance. Nevertheless, correct inhalation technique was markedly less frequent than in our previous studies.The most incorrectly used pharmacological groups continue to be the controller medications. A nonsignificant tendency among noncompliers to require more additional visits and to have worse clinical course and less knowledge about their disease than compliers was maintained.This type of evaluation continues to be useful in the clinical monitoring of therapeutic complicance in daily clinical practice. 相似文献

The objectives of this study were to determine the prevalence of asthma, atopy and COPD in Rwanda and to identify risk factors. The survey was conducted in Kigali, the Capital of Rwanda, and in Huye District, a rural area located in southern Rwanda.
Methods
A total of 2138 subjects were invited to participate in the study.1920 individuals (90%) answered to questionnaires on respiratory symptoms and performed spirometry, 1824 had acceptable spirograms and performed skin-prick test. In case of airflow obstruction (defined as pre-bronchodilator ratio FEV1/FVC < LLN) a post bronchodilator spirometry was performed. Reversibility was defined as an increase in FEV1 of 200 ml and 12% above baseline FEV1 after inhalation of 400 mcg of salbutamol.Results
The mean age was 38.3 years; 48.1% of participants were males and 51.9% females. Airflow obstruction was found in 256 participants (14%); 163(8.9%) subjects were asthmatics and 82 (4.5%) had COPD. COPD was found in 9.6% of participants aged 45 years and above. 484 subjects had positive skin-prick tests (26.5%); house dust mite and grass pollen mix were the main allergens. Risk factors for asthma were allergy, female gender and living in Kigali. COPD was associated with cigarette smoking, age and male sex.Conclusion
this is the first study which shows the prevalence of atopy, asthma and COPD in Rwanda. Asthma and COPD were respectively diagnosed in 8.9% and 4.5% of participants. COPD was diagnosed in 9.6% of subjects aged ≥45 years.The prevalence of asthma was higher in urban compared to rural area. 相似文献16.

To compare the perception of airway narrowing of nonasthmatic subjects with those having wheeze or mild asthma (doctor-diagnosed), the relationship between FEV1 and breathlessness was examined in 123 subjects from a general population sample. Scores for breathlessness, using the Borg scale, were recorded before and after inhaling incremental doses of methacholine to a maximal dose of 196 mcmol or a maximum change in FEV1 of 50%. A history of asthma symptoms, including wheeze in the previous 12 months, and doctor-diagnosed asthma was obtained by questionnaire. At any given level of FEV1 there was wide variation in Borg scores between subjects, however median Borg scores and the mean slope of Borg score on FEVI was greater in the asthmatic subjects or those with wheeze compared with nonasthmatic subjects or those without wheeze. In both nonasthmatic and asthmatic subjects, those with airway hyperresponsiveness had increased maximum symptom scores and maximum changes in FEVI, but similar Borg scores relative to change in FEVI, compared with those without hyperresponsiveness. We conclude that the perception of mild and moderate degrees of airway narrowing varies widely between individuals but is increased in subjects with a history of mild asthma or wheeze in the last 12 months, independently of airway responsiveness. 相似文献
