As cannabis use increases, physicians need to be familiar with the effects of both cannabis and tobacco on the lungs. However, there have been very few long-term studies of cannabis smoking, mostly due to legality issues and the confounding effects of tobacco. It was previously thought that cannabis and tobacco had similar long-term effects as both cause chronic bronchitis. However, recent large studies have shown that, instead of reducing forced expiratory volume in 1 s and forced vital capacity (FVC), marijuana smoking is associated with increased FVC...

BACKGROUND AND OBJECTIVE: There is growing evidence for anti-inflammatory activities of macrolides in chronic respiratory diseases, such as diffuse panbronchiolitis, cystic fibrosis, or chronic bronchitis. The long-term effect of macrolides in idiopathic pulmonary fibrosis (IPF) is unknown. This study was aimed to investigate the effect of macrolide therapy on the frequency of acute exacerbation (AE) and the mortality in IPF. METHODS: A total 52 IPF patients who were treated by combination of conventional agents with or without macrolides were retrospectively reviewed...

Better use of current antibiotics is warranted to curb increasing antimicrobial resistance rates. Procalcitonin guidance can safely reduce antibiotic usage when used to initiate or discontinue antibiotics in adult patients with a respiratory tract infection. However, the claimed reductions in antibiotic usage are mainly achieved in patients with acute bronchitis and exacerbations of COPD, conditions for which guidelines already discourage antibiotic treatment. Sequential procalcitonin measurements can also reduce the treatment duration of community-acquired pneumonia from 10-12 to 5-7 days, which is, however, already the recommended treatment duration for in- and outpatients under the current Dutch guidelines...

Pesticides are a family of compounds which have brought many benefits to mankind in the agricultural, industrial, and health areas, but their toxicities in both humans and animals have always been a concern. Regardless of acute poisonings which are common for some classes of pesticides like organophosphoruses, the association of chronic and sub-lethal exposure to pesticides with a prevalence of some persistent diseases is going to be a phenomenon to which global attention has been attracted. In this review, incidence of various malignant, neurodegenerative, respiratory, reproductive, developmental, and metabolic diseases in relation to different routes of human exposure to pesticides such as occupational, environmental, residential, parental, maternal, and paternal has been systematically criticized in different categories of pesticide toxicities like carcinogenicity, neurotoxicity, pulmonotoxicity, reproductive toxicity, developmental toxicity, and metabolic toxicity...

The direct toxicity of cigarette smoke and the body's subsequent response to this lung injury leads to a wide array of pathologic manifestations and disease states that lead to both reversible and irreversible injury to the large airways, small airways, alveolar walls, and alveolar spaces. These include emphysema, bronchitis, bronchiolitis, acute eosinophilic pneumonia, pulmonary Langerhans cell histiocytosis, respiratory bronchiolitis, desquamative interstitial pneumonia, and pulmonary fibrosis. Although these various forms of injury have different pathologic and imaging manifestations, they are all part of the spectrum of smoking-related diffuse parenchymal lung disease...

The club cell secretory protein (CCSP) is a regulator of lung inflammation following acute respiratory infection or lung injury. Recently, the relationship between CCSP and COPD has been reported. Since COPD results from an abnormal inflammatory response, we hypothesized that CCSP could have a protective role against chronic inflammation-induced lung damage. To address this issue, the pathophysiology of chronic lung inflammation induced by Pseudomonas aeruginosa in CCSP-deficient mice was determined. A tube of 5 mm in length was soaked in a fluid containing P...

Henoch Schonlein purpura (HSP) is an immune mediated disease associated Immunoglobulin A (IgA) deposition within the affected organs. While the disease is commonly seen in the pediatric age group, it is rarely seen in adults. We report the case of a 93-year-old Caucasian lady who presented with nonthrombocytopenic purpuric rash and acute kidney injury after an episode of bronchitis. Rapid and progressive deterioration of renal function prompted a kidney biopsy, which showed findings consistent with IgA nephropathy confirming the diagnosis of HSP...

Infectious bronchitis virus (IBV) causes major losses in the poultry industry. The safe and effective vaccine to control IBV spread is imperative. In the present study, we developed IBV S1 glycoprotein poly-epitope-based DNA vaccine pV-S1B+S1T consisting of SH1208 and Holte strain BF2-restricted T cell epitopes and Australian T strain dominant B cell neutralization epitopes. Specific pathogen-free chickens were vaccinated with pV-S1B+S1T and control plasmids twice to elicit strong humoral and cellular immune response, as indicated by viral neutralization titers and results of CD8(+) T cell proliferation assays...

The common respiratory tract infections of acute bacterial sinusitis, acute exacerbation of chronic bronchitis, and community-acquired pneumonia are responsible for millions of physician office visits every year. Despite advances in diagnostic testing and the development of new antimicrobial agents, these infections continue to contribute significantly to patient morbidity and mortality worldwide. Physicians are faced with multiple challenges in the management of patients with these diseases. These challenges include the selection of appropriate empiric therapy, the increasing emergence of resistant pathogens, patient noncompliance with therapeutic regimens, and the pressure to use costeffective agents...

Xanthium strumarium L. (Asteraceae), a traditional Chinese medicine, is prescribed to treat arthritis, bronchitis, and rhinitis. Although the plant has been used for many years, the mechanism by which it ameliorates various inflammatory diseases is not yet fully understood. To explore the anti-inflammatory mechanism of methanol extracts of X. strumarium (Xs-ME) and its therapeutic potential, we used lipopolysaccharide (LPS)-stimulated murine macrophage-like RAW264.7 cells and human monocyte-like U937 cells as well as a LPS/D-galactosamine (GalN)-induced acute hepatitis mouse model...

Background. The clinical diagnosis of pneumonia is sometimes difficult since chest radiographs are often indeterminate. In this study, we aimed to assess whether serum C-reactive protein (CRP) could assist in identifying patients with pneumonia. Methods. For one winter, all consecutive patients with acute respiratory symptoms admitted to the emergency ward of a single center were prospectively enrolled. In addition to chest radiographs, basic laboratory tests, and microbiology, serum levels of CRP were measured at entry...

Infectious bronchitis (IB) is an acute and highly contagious viral respiratory disease of chickens and vaccination is the main method for disease control. The S1 protein, which contains several virus neutralization epitopes, is considered to be a target site of vaccine development. However, although protective immune responses could be induced by recombinant S1 protein, the protection rate in chickens was still low (<50%). Here, we generated fused S1 proteins with HA2 protein (rS1-HA2) or transmembrane domain and cytoplasmic tail (rS1-H3(TM)) from hemagglutinin of H3N2 influenza virus...
