Efficacy and effectiveness of omalizumab in the treatment of childhood asthma
2018
Omalizumab is a monoclonal antibody that binds and inhibits free serum immunoglobulin E, a mediator involved in the clinical manifestations of allergic asthma. Evidence for its efficacy and safety in the treatment of moderate-to-severe allergic asthma is based primarily on studies in adolescents and adults. However, there is increasing evidence of its utility in children with allergic asthma aged 6-12 years. Areas covered: This article reviews efficacy, safety, and effectiveness of omalizumab in the treatment of moderate-to-severe allergic asthma in children aged 6-12 years in clinical trials and in studies in clinical practice. Pharmacoeconomic aspects of its use among this population and …
Anti-interleukin-5 therapy (mepolizumab) in life-threatening asthma attack: A case-based discussion
2019
We report about a case of a compassionate off-label use of the anti-interleukin-5-agent mepolizumab in a ventilated patient with life-threatening asthma attack in eosinophilic asthma. The patient suffered from severe eosinophilic asthma and was transmitted to our hospital with an asthma attack and a life-threatening respiratory state under ventilation. Since high dose steroids had not yielded a sufficient respiratory improvement mepolizumab was administered subcutaneously. After administration of mepolizumab respiratory state and ventilation parameter improved significantly. Two days after administration the patient was weaned could be extubated 8 days later and recovered completely from th…
Role of menopause and hormone replacement therapy in sleep-disordered breathing
2020
There are suggestions that the loss of female sex hormones following menopause is critical for the development or progression of sleep-disordered breathing (SDB). We conducted a review of the literature on the role of menopause and hormone replacement therapy (HRT) in SDB risk. There is an increase in SDB during the menopausal transition period, but data on an effect beyond that of increasing age and changes in body habitus are weak or absent. Early community-based, observational studies reported a protective effect by HRT on SDB prevalence, but this could possibly be explained as a healthy user effect. Interventional studies of the effect of HRT on SDB are sparse, with only a few randomize…
CAT score single item analysis in patients with COPD: results from COSYCONET
2019
Abstract The COPD Assessment Test (CAT) is in widespread use for the evaluation of patients with chronic obstructive pulmonary disease (COPD). We assessed whether the CAT items carry additional information beyond the sum score regarding COPD characteristics including emphysema. Patients of GOLD grades 1 to 4 from the COPD cohort COSYCONET (German COPD and Systemic Consequences - Comorbidities Network) with complete CAT data were included (n = 2270), of whom 493 had chest CT evaluated for the presence of emphysema. Comorbidities and lung function were assessed following standardised procedures. Cross-sectional data analysis was based on multiple regression analysis of the single CAT items ag…
Effect of unilateral diaphragmatic paralysis on postpneumonectomy lung growth.
2013
Respiratory muscle-associated stretch has been implicated in normal lung development (fetal breathing movements) and postpneumonectomy lung growth. To test the hypothesis that mechanical stretch from diaphragmatic contraction contributes to lung growth, we performed left phrenic nerve transections (PNT) in mice with and without ipsilateral pneumonectomy. PNT was demonstrated by asymmetric costal margin excursion and confirmed at autopsy. In mice with two lungs, PNT was associated with a decrease in ipsilateral lung volume ( P < 0.05) and lung weight ( P < 0.05). After pneumonectomy, PNT was not associated with a change in activity level, measureable hypoxemia, or altered minute venti…
Evaluation of Health Outcomes in Elderly Patients With Asthma and COPD Using Disease-Specific and Generic Instruments
2001
Abstract Objectives To compare the effects of asthma and COPD on health status (HS) in elderly patients, and to assess the correlation between disease-specific and generic instruments assessing HS. Design Multicenter, cross-sectional, observational study. Setting The Salute Respiratoria nell'Anziano (respiratory health in the elderly) Study network of outpatient departments. Patients One hundred ninety-eight asthma patients and 230 COPD patients ≥ 65 years old. Measurements HS was assessed by the Saint George's Respiratory Questionnaire (SGRQ) and five generic outcomes: Barthel's index, 6-min walk test, mini mental state examination, geriatric depression scale (GDS), and quality-of-sleep in…
Airway inflammation in healthy smokers
2012
Cigarette smoking is a risk factor associated with lung cancer and many other neoplasms of various organs, coronary artery disease and numerous vascular disorders, Chronic Obstructive Pulmonary Disease (COPD) and other types of lung diseases [13]. Much work has been done on the in vitro and ex vivo carcinogenetic effects of tobacco smoking while the effects of smoking on innate and adaptive immune function have been studied to a lesser degree. Recent data suggests that cigarette smoke alters the functions of the immune system and increases susceptibility to viral and bacterial infections [4-6]. In the respiratory system along the last years many studies have depicted the changes induced by …
The murine bronchopulmonary microcirculation in hapten-induced inflammation
2006
ObjectiveThe clinical observation of central bronchial artery hypertrophy in chronic lung inflammation suggests the possibility that the bronchial circulation may also participate in adaptive responses in peripheral lung inflammation.MethodsTo investigate the potential role of the bronchial microcirculation in peripheral lung inflammation, we developed a murine model of lung inflammation using the intratracheal instillation of the peptide-hapten trinitrophenol in presensitized mice.ResultsClinical parameters indicated a peak inflammatory response at 96 hours. Similarly, gross and microscopic evidence of inflammation was observed 96 hours after antigen instillation. Using a forced oscillatio…
Mild obstructive sleep apnoea: clinical relevance and approaches to management
2015
Summary Obstructive sleep apnoea is highly prevalent in the general population worldwide, especially in its mild form. Clinical manifestations correlate poorly with disease severity measured by the apnoea–hypopnoea index (AHI), which complicates diagnosis. Full polysomnography might be more appropriate to assess suspected mild cases because limited ambulatory diagnostic systems are least accurate in mild disease. Treatment options in mild obstructive sleep apnoea include continuous positive airway pressure (CPAP) and oral appliance therapy, in addition to positional therapy and weight reduction when appropriate. The superior efficacy of CPAP in reducing AHI is offset by greater tolerance of…
Solitäre fibröse Pleuratumoren - Seltene Tumoren mit unvorhersehbarem klinischen Verhalten
2000
Solitary fibrous tumors of the pleura are rare tumors with unpredictable clinical behaviour. We report about two patients with an incidental finding of an intrathoracic tumor. Preoperative diagnosis was uncertain. In both patients, a solid tumor of the pleura was resected en bloc in combination with a wedge resection of the lung following anterolateral thoracotomy. The postoperative course was eventful. Six months after primary complete resection there were no signs of tumor recurrence.
