The objective of this study was to compare the efficacy and safety of the second controller medications (long-acting beta2-agonist, leukotriene receptor antagonist and sustained-release theophylline) used in addition to inhaler corticosteroid treatment in moderate persistent asthma. A total of 64 patients with asthma, in the moderate persistent asthma category, were divided into three groups. Patients, all of whom were concurrently using inhaled corticosteroid (Budesonide 400 microg twice daily), were treated for 3 months with either inhaled formoterol 9 microg twice daily (first group), oral zafirlukast 20 mg twice daily (second group), or sustained-release theophylline 400 mg once daily (third group). All of the patients were subjected to assessments on the subject of peak expiratory flow (PEF) variability, forced expiratory volume in 1 sec (FEV1), asthma symptom scores (daytime and night-time), supplemental terbutalin use, asthma exacerbations and adverse events. Over the 3-month treatment period. In all of the three groups, significant improvements were recorded in the lung function, asthma symptom scores and supplemental terbutalin use criteria, as a result oftreatments applied. Formoterol treatment resulted in significantly greater and earlier improvements compared with the other two groups in several criteria: PEF variability (17.9 +/- 2.5; 21.9 +/- 3.2; 23.7 +/- 3.3; P < 0.001); asthma symptom score (daytime) (1.6 +/- 0.5; 1 +/- 0.5; 2.0 +/- 0,5; P < 0.05); asthma symptom score (night-time) (1.2 +/- 0.4; 2.2 +/- 0.5; 16 +/- 0.6; P < 0001); and supplement alter butalin use (1.2 +/- 0.3; 1.8 +/- 0.5; 1.7 +/- 0.5; P < 0.05). However, at the end of the treatment, in all of the three groups studied, improvements were attained in overall asthma control and there was no statistical difference among the groups. Although there were no side effects which required the discontinuation of the treatment, it was observed that the maximum side effect was in the second group (20%, 31.6% and 20%, respectively). In conclusion, in patients who still have symptoms on treatment with inhaled corticosteroids, the addition of a long-acting beta2-agonist, leukotriene antagonists or sustained-release theophylline to the treatment is a logical approach, and, in addition to inhaled corticosteroids, any one of these second controller medications may be chosen in patients with moderate asthma.
Exposure to cockroach has been identified as an important source of indoor allergens in patients with asthma and allergic rhinitis. We evaluated the relationship between cockroach sensitivity and other allergens in patients with asthma. A total of 114 patients, defined asthma according to GINA, were enrolled in this study. A questionnaire including age, sex, duration of asthma, history of cockroach presence at home, and total IgE, blood eosinophil count, pulmonary function tests, standard skin prick test additional cockroach and shrimp allergen were performed. There were 84 (73.7%) female and 30 (26.3%) male patients with a mean age of 38.1+10.1 years. The average duration of asthma was 7.7+7.2 years. Sixty five (57%) patients were determined atopic and 49 (43%) nonatopic. Pollen allergen was the most common allergen in 59 (51.8%) patients with asthma, and second common allergen was mite allergen in 43 (37.7%) patients. Cockroach sensitivity were detected in 23 (20.2%) of 114 all asthmatics and 23 (35%) of atopic asthmatics. High rates of house-dust-mite allergy (73.9%) was determined in patients with cockroach sensitivity (P<0.05), while we found no relationship with other allergens. There was no difference for cockroach sensitivity between rural and urban population. Cockroach sensitivity was more common in mild bronchial asthmatics and a female predominance was observed. In addition, there was no association between shrimp and cockroach sensitivity. As a result, a high rate of cockroach sensitivity alone or with mite sensitivity was seen in patients with bronchial asthma in Turkish population. Because of cross-reactivity between mites and cockroach, cockroach sensitivity should be investigated in patients with house-dust-mite allergy. In addition, a high rate of cockroach sensitivity, in terms of IgE sensitization, may be important for the development of new sensitizations.
Foreign body aspiration has a wide range of outcomes, including immediate resolution, acute asphyxia, recurrent pulmonary disease and death. A 52-year-old man was misdiagnosed with asthma and pneumonia for 6 months. A thoracic computed tomography (CT) scan showed an endobronchial lesion in the right main bronchus. Fiberoptic bronchoscopy was performed and the teeth were detected in the right main bronchus, in addition to tracheal bronchus. Aspirated teeth were removed using a rigid bronchoscope under general anesthesia. The patient having a trauma should always be carefully and systematically examined for foreign bodies. A rapid diagnosis depends on high clinical suspicion, clinical signs and radiological findings and the clinician must be aware of all complications of foreign body aspiration.
We have shown that the methacholine challenge test is the most valuable diagnostic tool for asthma. In addition, there is a significant correlation between the methacholine challenge test and some patient symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
