Nontuberculous mycobacteria (NTM) are ubiquitous organisms in the environment and are now increasingly being recognized as significant causes of chronic pulmonary infection in immunocompetent individuals (1). The most frequently encountered NTM lung disease worldwide is caused by Mycobacterium avium-intracellular complex (MAC) (2-4). In several studies with chest computed tomography (CT), researchers have demonstrated that the presence of bilateral multifocal bronchiolitis (well-defined small nodules and branching centrilobular nodules, or tree-in-bud pattern) and bronchiectasis distributed mainly in the right middle lobe and lingular segment are indicative of NTM pulmonary infection (7-11). Accordingly, it is believed that radiologic findings of bilateral bronchiolitis and bronchiectasis on chest CT scans specifically suggest NTM pulmonary infection (1). These CT findings, however, may not be specific for NTM pulmonary infection. CT patterns of bronchiectasis and bronchiolitis in the pulmonary infections caused by various NTM organisms have been reported, and these organisms include Mycobacterium kansasii, Mycobacterium xenopi, and rapidly growing mycobacteria such as Mycobacterium abscessus, Mycobacterium fortuitum, and Mycobacterium chelonae (12-14). In addition, not all patients with bronchiectasis and bronchiolitis have NTM pulmonary infection. Two recent studies showed that only about 50% of patients with such CT features have MAC pulmonary infection (9,15). To the best of our knowledge, however, there is no report about the incidence of NTM in patients with bronchiectasis or bronchiolitis in countries with low incidence of TB. Thus, the purpose of our study was to determine the frequency of NTM pulmonary infection in patients with bilateral bronchiectasis and bronchiolitis at chest CT and to investigate whether these CT findings are specifically indicative of MAC infection or other specific pathogen.
The present study investigated the influence of respiratory affections on the heart rate variability (HRV) of paediatric patients. We have hypothesised that respiratory physiotherapy would promote a beneficial effect on the cardiac autonomic modulation. Twenty-four children, who were divided into respiratory disease group (RG) and control (CG) groups, were studied. Analysis of HRV was performed with the RG in the dorsal decubitus position during four different moments: basal record (30 minutes); 5 minutes after respiratory physiotherapy by means of airway clearance techniques (10-minute record); 5 minutes after nasotracheal suction (10-minute record); and 40 minutes after nasotracheal suction (30-minute record). CG group was submitted to the same protocol, except nasotracheal suction, which was not performed due to ethical reasons.
Immunosuppression is a key intervention in patients with solid organ transplant and is usually achieved by combination therapy with systemic CsA or tacrolimus with azathioprine, mycophenolate mofetil (MMF), or corticoids. However, the outcomes after lung transplantation are poor when compared with those after heart, kidney, or liver transplantation, with a survival rate of only 55% for recipients of lung transplants. Additional application of aerosolised L-CsA should suppress T-cell activation in the lung tissue and subsequently BOS development. The overall purpose of this phase-II/III study is to obtain efficacy and safety data of L-CsA in the prevention of BOS.
[Study Objectives] - To evaluate the efficacy of azithromycin, N-acetylcystein, and inhaled corticosteroid combination therapy in patients with bronchiolitis obliterans as a complication of allogeneic hematopoietic cell transplantation in terms of response rate at 6 months after treatment initiation based on the improvement of FEV1.
The aim of this case-control study is the characterization of the bronchial and systemic inflammation of children and young adults with bronchiolitis obliterans. On the first visit subjects are asked to perform a lung function test (spirometry, body plethysmography with helium). Further levels of eNO and eCO are determined. A blood sample is drawn to describe the inflammatory status. Bronchial inflammation will be measured in induced sputum. At the second visit, a non-specific bronchial provocation testing (PD20 FEV1 methacholine) is performed.
This phase II trial studies how well giving fluticasone propionate, azithromycin, and montelukast sodium (FAM) together works in treating patients with bronchiolitis obliterans who previously underwent stem cell transplant. FAM may be an effective treatment for bronchiolitis obliterans
Acute bronchiolitis is the main cause for respiratory illness that requires hospitalization in children younger than 2 years. In the United States it has been shown that the burden of the disease is considerable, having an annual cost of more than $ 500 million and being responsible for the 17% of all infant hospitalizations . Aim of the present study was to verify the effects of nebulized 3% saline solution in comparison to normal saline in addiction to epinephrine in a large population of RSV positive cases of bronchiolitis; all patients presented a disease as much as severe to require hospitalization.The main study endpoints were the length of stay in hospital and the clinical response.
The aim of the investigators study is to compare in children aged less than 18 months and hospitalized for an acute viral bronchiolitis the efficacy of the HS 3% (Mucoclear®, sterile ampoules of 4 ml) nebulised with a conventional jet-nebulizer (particles diameter of 4-5 µm), or with a jet-nebulizer adapted for infants (particles diameter of 2-2.5 µm), or with a mesh-nebulizer adapted for infants (particles diameter of 2-2.5 µm).
Background: - Bronchiolitis obliterans or bronchiolitis obliterans syndrome is a lung disorder that occurs as a complication of either lung transplantation or bone marrow/blood stem cell transplantation. One of the complications of transplant is the occurrence of graft versus host disease (in hematopoietic stem cell transplants) and host versus graft disease (in lung transplantation). In these diseases, the cells attack the lungs and cause irreversible small airway fibrosis referred to as bronchiolitis obliterans syndrome. When a patient develops fibrosis of the lungs or bronchioles, the lungs no longer work properly, which causes difficulties with breathing that lead to a diminished quality of life and an increased risk of death. Treatment typically involves immunosuppressive therapy such as oral cyclosporine or steroid therapy, but these treatments are only marginally effective and can cause significant toxicities and increase the risk of infections. Inhaled cyclosporine (CIS) achieves higher concentrations of cyclosporine in the lungs and lower concentrations of cyclosporine in the blood than oral cyclosporine. Therefore, it could have advantages over conventional oral immunosuppressive therapies used to treat this disorder. Researchers are interested in testing whether inhaled cyclosporine therapy could be used as a safe and effective treatment for bronchiolitis obliterans or bronchiolitis obliterans syndrome occurring after bone marrow/blood stem cell or lung transplants. Objectives: - To evaluate whether inhaled cyclosporine (CIS) can improve or stabilize lung function and quality of life in individuals with bronchiolitis obliterans. Eligibility: - Individuals between 10 and 80 years of age who have been diagnosed with bronchiolitis obliterans or bronchiolitis obliterans syndrome after blood or lung transplants. Design: - Participants will be screened with a full medical history and physical examination, as well as blood and urine tests, lung function tests, imaging studies, bronchoalveolar lavage samples, and quality of life questionnaires. - Participants will take cyclosporine inhalation solution through a nebulizer. The nebulizer generates a mist of cyclosporine inhalation solution (CIS), which is then breathed in through a mouthpiece. The process takes approximately 20 minutes. The solution will be provided in single-use vials. - Participants will continue to take all medications for post-transplant care as required by their doctor and the study researchers. Attempts will be made to reduce the doses and types of immunosuppressants given to participants on the study, as long as the treatment continues to produce improved or stable lung function. - Participants will have study visits every 3 weeks with blood and urine tests, lung function tests, and imaging studies. Participants will undergo repeat bronchoalveolar sample at week 9 and 18. Participants will also complete quality of life questionnaires as directed. Treatment will continue for a minimum of 18 weeks, followed by a final follow-up visit 2 weeks after the end of the study. - Participants who benefit from the inhaled cyclosporine (CIS) may continue to receive further therapy with inhaled cyclosporine at the end of the study by participation in a separate study extension.
