BACKGROUND: Exacerbations of asthma and COPD are a major cause of morbidity and mortality and are responsible for significant health care costs. This study further investigates interleukin (IL)-1 pathway activation and its relationship with exacerbations of asthma and COPD. METHODS: In this prospective cohort study, 95 participants with stable asthma (n=35) or COPD (n=60) were recruited and exacerbations recorded over the following 12 months. Gene expressions of IL-1 pathway biomarkers, including the IL-1 receptors (IL1R1, IL1R2, and IL1RN), and signaling molecules (IRAK2, IRAK3, and PELI1), were measured in sputum using real-time quantitative polymerase chain reaction...

BACKGROUND: Lung clearance index (LCI), a measure of ventilation inhomogeneity derived from a multiple-breath washout test, is a promising tool for assessing airway function in patients with non-cystic fibrosis bronchiectasis. However, it is unknown whether ventilation inhomogeneity could improve after successful elimination of excessive secretions within bronchiectasis. The objective of this work was to assess the short-term effects of lung secretion clearance using the autogenic drainage technique on standard lung function tests and LCI in subjects with non-cystic fibrosis bronchiectasis...

Lung infections with multiresistant pathogens are a major problem of patients suffering from cystic fibrosis (CF). N-chlorotaurine (NCT), a microbicidal active chlorine compound with no resistance development, is well tolerated upon inhalation. The aim of this study was to investigate NCT on its bactericidal and fungicidal activity in vitro in artificial sputum medium (ASM) mimicking the composition of cystic fibrosis mucus.The medium was inoculated with bacteria (Staphylococcus aureus including some MRSA strains, Pseudomonas aeruginosa, Escherichia coli) or spores of fungi (Aspergillus fumigatus, Aspergillus terreus, Candida albicans, Scedosporium apiospermum, Scedosporium boydii, Lomentospora prolificans, Scedosporium aurantiacum, Scedosporium minutisporum, Exophiala dermatitidis, Geotrichum sp...

RATIONALE: Previous work indicates that ivacaftor improves CFTR activity and lung function in people with cystic fibrosis (CF) and G551D-CFTR mutations, but does not reduce density of bacteria or markers of inflammation in the airway. These findings raise the possibility that infection and inflammation may progress independently of CFTR activity once CF lung disease is established. OBJECTIVES: To better understand the relationship between CFTR activity, airway microbiology and inflammation, and lung function in subjects with CF and chronic airway infections...

Current US guidelines recommend longer treatment for tuberculosis (TB) caused by pyrazinamide-resistant organisms (e.g., Mycobacterium bovis) than for M. tuberculosis TB. We compared treatment response times for patients with M. bovis TB and M. tuberculosis TB reported in the United States during 2006-2013. We included culture-positive, pulmonary TB patients with genotyping results who received standard 4-drug treatment at the time of diagnosis. Time to sputum-culture conversion was defined as time between treatment start date and date of first consistently culture-negative sputum...

The increased expression of placental growth factor (PlGF) in chronic obstructive pulmonary disease and allergy-related asthma suggests its role in the pathogenesis of these diseases. In asthmatic smokers, airway remodelling is accompanied by an accelerated decline in lung function. However, whether PlGF contributes to the persistent airflow obstruction and vascular remodelling typically seen in asthmatic smokers is unknown. In this study we measured lung function, airway-wall thickening, and PlGF levels in serum and induced sputum in 74 asthmatic and 42 healthy smokers and never-smokers...

Supportive care and pharmacological treatment can improve the quality of life of people with end-stage chronic obstructive pulmonary disease (COPD) who cope on a daily basis with substantial physical, psychological, social and spiritual morbidity. Smoking cessation is the only intervention that reduces the rate of progression of COPD, but evidence-based drug treatments and non-pharmacological strategies can relieve symptoms and reduce the impact of exacerbations. People with severe COPD live with increasingly troublesome breathlessness and other symptoms such as fatigue, pain, sputum production and weight loss...

Since severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronaviruses (CoVs) share similar characteristics with respect to clinical signs, etiology, and transmission, methods for a rapid and accurate differential diagnosis are important. Therefore, the aim of this study was to develop a duplex real-time reverse transcription (RT)-PCR method for the simultaneous detection of these viruses. Primers and probes that target the conserved spike S2 region of human SARS-CoV, MERS-CoV, and their related bat CoVs were designed...

BACKGROUND: Congenital tuberculosis is a rare manifestation of tuberculosis. The diagnosis is often delayed, especially in preterm neonates because of the non-specific clinical presentation and the lack of awareness of maternal disease prior to pregnancy. CASE PRESENTATION: We report a case of congenital tuberculosis in an infant born at 24 weeks of gestation to a mother who presented with uncontrolled seizures during preterm labor. Maternal diagnosis was initially made by placental pathology, and later confirmed by isolation of Mycobacterium tuberculosis in urine, gastric aspirates and sputum...

BACKGROUND: Anti-inflammatory therapy is a logical approach to slowing the inevitable lung function deterioration in cystic fibrosis (CF) patients. This study's aim was to evaluate inflammatory markers and disease progression in paediatric CF patients chronically treated with azithromycin or low-dose prednisolone. METHODS: The study included 204 patients with CF and 100 healthy controls; 102 CF patients were treated with basic therapy only (without anti-inflammatory treatment; WAT), and 102 individuals received basic therapy along with azithromycin (n = 59) or low-dose prednisolone (n = 43)...

BACKGROUND: Non-invasive ventilation may be a means to temporarily reverse or slow the progression of respiratory failure in cystic fibrosis by providing ventilatory support and avoiding tracheal intubation. Using non-invasive ventilation, in the appropriate situation or individuals, can improve lung mechanics through increasing airflow and gas exchange and decreasing the work of breathing. Non-invasive ventilation thus acts as an external respiratory muscle. This is an update of a previously published review...

BACKGROUND Kaposi sarcoma (KS) is known to involve the mucocutaneous tissues and the aero-digestive tracts. In acquired immune deficiency syndrome (AIDS) patients, KS has an aggressive course and carries poor prognosis. We present a case of pulmonary KS with osseous metastases as the first presentation of human immunodeficiency virus (HIV) infection in a young male. The lesions impressively decreased in size and numbers following initiation of highly active antiretroviral therapy (HAART). CASE REPORT A 34-year-old heterosexual male presented with a one month history of cough and 15-20 pound weight loss within six months...

Currently, the data on pneumococcal invasive disease in the Indonesian population are limited. In this study, we investigated the serotype distribution and antimicrobial susceptibility of Streptococcus pneumoniae. These samples were isolated from the sputum of adult patients with non-specific clinical symptoms aged 18-87 years in Jakarta, Indonesia, from August to October 2014. Of the 349 sputum specimens, thirteen isolates were identified as S. pneumoniae strains (4%), with two strains each for serotype 19F, 3, and 15A, and one strain each for serotype/serogroup 13, 23A, 6, 34, 17F, 16F, and untypeable...
