Yu Shen, Qiu-Xia Qu, Meng-Ni Jin, Cheng Chen
BACKGROUND: Recently, lymphoid follicle-confined and circulating CD8+ T-cells expressing the C-X-C chemokine receptor type 5 (CXCR5) were described, which was involved in anti-virus immune response. However, the dynamics and role of circulating CXCR5-expressing CD8+ T-cells during bacterial infection is unknown. So, we asked whether CXCR5+ CD8+ T cells were also generated during bacterial infections in lower respiratory tract. METHODS: The clinical data of 65 pneumonia patients were analyzed...

Bronchiectasis has historically been considered to be irreversible dilatation of the airways, but with modern imaging techniques it has been proposed that 'irreversible' be dropped from the definition. The upper limit of normal for the ratio of airway to arterial development increases with age, and a developmental perspective is essential. Bronchiectasis (and persistent bacterial bronchitis, PBB) is a descriptive term and not a diagnosis, and should be the start not the end of the patient's diagnostic journey...

Bronchiectasis has received increased attention recently, including an emphasis on preventing infective exacerbations that are associated with disease progression and lung function decline. While there are several bacteria and viruses associated with bronchiectasis, licensed vaccines are only currently available for Streptococcus pneumoniae, Haemophilus influenzae (H. influenzae protein D as a conjugate in a pneumococcal vaccine), Mycobacterium tuberculosis, Bordetella pertussis and influenza virus. The evidence for the efficacy and effectiveness of these vaccines in both preventing and managing bronchiectasis in children and adults is limited with the focus of most research being on other chronic lung disorders, such as chronic obstructive pulmonary diseases, asthma and cystic fibrosis...

Impaired lung function is common in people with a history of tuberculosis. Host-directed therapy added to tuberculosis treatment may reduce lung damage and result in improved lung function. An understanding of the pathogenesis of pulmonary damage in TB is fundamental to successfully predicting which interventions could be beneficial. In this review, we describe the different features of TB immunopathology that lead to impaired lung function, namely cavities, bronchiectasis, and fibrosis. We discuss the immunological processes that cause lung damage, focusing on studies performed in humans, and using chest radiograph abnormalities as a marker for pulmonary damage...

Background: Patients with tuberculosis-destroyed lungs (TDLs), with airflow limitation, have clinical characteristics similar to those of patients with chronic obstructive pulmonary disease (COPD). Acute exacerbation is an important factor in the management of TDL. Therefore, the aim of this study was to investigate the factors associated with acute exacerbations in patients with stable TDL with airflow limitation. Methods: We evaluated the clinical characteristics, such as lung function, image findings, and serum laboratory findings, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and interleukin (IL)-6, in patients with TDL with chronic airflow limitation (n=94)...

Antibiotics are frequently prescribed to children in the community and in nosocomial settings, mainly because of lower respiratory tract infections(LRTIs), which include influenza, bronchitis, bronchiolitis, pneumonia, and tuberculosis, in addition to bronchiectasis and cystic fibrosis lung disease. It is important to note, however, that more than 50% of these prescriptions are unnecessary or inappropriate. Areas covered: The current choice of antimicrobial therapy for etiological agents of LRTIs is examined and discussed considering each type of LRTI...

What differentiates Mycobacterium abscessus from other saprophytic mycobacteria is the ability to resist phagocytosis by human macrophages and the ability to multiply inside such cells. These virulence traits render M. abscessus pathogenic, especially in vulnerable hosts with underlying structural lung disease, such as cystic fibrosis, bronchiectasis or tuberculosis. How patients become infected with M. abscessus remains unclear. Unlike many mycobacteria, M. abscessus is not found in the environment but might reside inside amoebae, environmental phagocytes that represent a potential reservoir for M...
