TB, chronic obstructive airway disease

Muhammad Irfan
Tuberculosis (TB) is among the top infectious causes of morbidity and mortality worldwide and is associated with frequent pulmonary damage despite microbiological cure. Patients with treated TB may remain lifelong sufferers of disabling structural and functional sequelae of the disease, which subsequently impair quality of life. Long-term follow-up studies have revealed that many patients with treated pulmonary TB show signs of permanent impairment of their lung function. Impairment is variable in pattern and severity, ranging from none to severe, and shows restrictive, obstructive, or mixed patterns...

There is little long-term follow-up data concerning the association between past pulmonary tuberculosis (TB), airway obstruction and mortality. We aimed to analyse a national health examination survey data from 6701 adult Finns undergoing spirometry between 1978 and 1980 (follow-up through 2013). We identified TB either through a disease history or by a TB-indicative scar on a chest x-ray. We specified obstruction using the lower limit of normal (LLN) and classified severity using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages 1-4...

BACKGROUND AND OBJECTIVES: Pneumocystis jirovecii pneumonia (PJP) is a chronic fungal infection that caused by P. jirovecii. Disease is more prevalent among the HIV-infected patients. The colonization of pneumocystis in human respiratory system is associated with the airway inflammation and obstruction. The current study was conducted to identify the prevalence of P. jirovecii among the patients with chronic pulmonary disorders in Ahvaz, Iran. MATERIALS AND METHODS: In the present study, 115 bronchoalveolar lavage (BAL) specimens were collected from patients...

Hemoptysis is the expectoration of blood from the lung parenchyma or airways. The initial step in the evaluation is determining the origin of bleeding. Pseudohemoptysis is identified through the history and physical examination. In adults, acute respiratory tract infections (e.g., bronchitis, pneumonia), bronchiectasis, asthma, chronic obstructive pulmonary disease, and malignancy are the most common causes. Tuberculosis is a major cause of hemoptysis in endemic regions of the world. Although tuberculosis rates are low in the United States, they are increased in persons who are homeless or who were born in other countries; consideration for testing should be made on an individual basis...

SESSION TITLE: Bronchology/Interventional Student/Resident Case Report Posters IISESSION TYPE: Medical Student/Resident Case ReportPRESENTED ON: Tuesday, October 28, 2014 at 01:30 PM - 02:30 PMINTRODUCTION: A broncholith is a calcified material in the bronchus. As a result of the relatively low incidence of this disease, broncholithiasis has often been neglected in the differential diagnosis of hemoptysis. As a result, patients have been wrongly tagged with more common diseases causing bronchial obstruction, thereby losing the benefit of prompt diagnosis and therapy...

UNLABELLED: The C-type lectin receptor Dectin-1 is expressed mainly on myeloid cells mediating the immune response targeting respiratory pathogens such as Aspergillus fumigatus and Mycobacterium tuberculosis. The pulmonary epithelium serves as an important interface for interactions between these pathogens and the respiratory tract. Therefore, we analyzed the expression pattern of Dectin-1 in the human lung. Immunohistochemically stained human lung sections from 17 out of 19 individuals were positive for Dectin-1, which was expressed mainly apically on bronchial and alveolar epithelium...

Collectively asthma, chronic obstructive pulmonary disorder (COPD) and cystic fibrosis (CF) are very common, important causes of disease and ill health. Filamentous fungal colonisation of the airways can occur in all three disease groups, although the clinical relevance is unclear. Allergic bronchopulmonary aspergillosis (ABPA) is a well-recognised severe complication of airway colonisation associated primarily with Aspergillus fumigatus. Fungal colonisation may have a deleterious effect without fulfilling all the diagnostic criteria of ABPA; however, a lack of standardisation in processing respiratory samples hampers comparisons...

SETTING: Aspergillus complicates the course of healed pulmonary tuberculosis (PTB), causing aspergilloma and chronic pulmonary aspergillosis. Whether Aspergillus also causes allergic sensitisation in PTB-related fibrocavitary disease and bronchiectasis remains unknown. OBJECTIVE: To investigate the prevalence of Aspergillus sensitisation in healed fibrocavitary PTB. DESIGN: In a case-control design, consecutive symptomatic new referrals with PTB-related fibrocavitary disease underwent spirometry, Aspergillus skin test and computed tomography of the chest, determination of serum IgE levels (total and Aspergillus fumigatus-specific), serum precipitins against A...

Pulmonary delivery of locally-acting drugs encapsulated in nanocarriers provides several advantages for the treatment of respiratory diseases such as asthma, chronic obstructive pulmonary diseases, cystic fibrosis, tuberculosis and lung cancer. These advantages include, among others, sustained drug delivery to the lungs, reduced therapeutic dose and improved patient compliance. The aim of this review is to give an updated overview on recent advances recorded in the last few years in this field as well as on the major challenges still existing and that remain to be overcome before any clinical application...

Retropharyngeal abscess is a rare, deep seated infection of the neck that usually affects young children. Chronic retropharyngeal abscess is rare and results from tuberculosis of the spine. Such swelling in the neck gradually increases in size and is detected during the routine radiological screening for symptoms like pain, dysphagia, fever, dyspnoea, progressive inspiratory stridor (from laryngeal obstruction), neck hyperextension etc, but rarely leads to sudden death due to airway obstruction. Thus the forensic pathologist rarely comes across such type of cases...

Until recently, little attention has been given to chronic lung disease (CLD) in HIV-infected children. As the HIV epidemic matures in sub-Saharan Africa, adolescents who acquired HIV by vertical transmission are presenting to health services with chronic diseases. The most common is CLD, which is often debilitating. This review summarizes the limited data available on the epidemiology, pathophysiology, clinical picture, special investigations and management of CLD in HIV-infected adolescents. A number of associated conditions: lymphocytic interstitial pneumonitis, tuberculosis and bronchiectasis are well described...

BACKGROUND: An association between chronic obstructive pulmonary disease (COPD) and tuberculosis (TB) has been described, mainly due to smoking and corticosteroid use. Whether inhaled corticosteroid (ICS) therapy is associated with an increased risk of TB remains unclear. METHODS: We selected COPD cases by using six diagnostic scenarios and control subjects from a nationwide health insurance database, and applied time-dependent Cox regression analysis to identify the risk factors for TB...

IL-27 is involved in inflammatory reactions. CXCL10 is an important chemokine contributing to airway inflammatory disease. In this study, we investigated whether IL-27 modulated the synthesis of CXCL10 in primary human lung fibroblasts (HLFs). HLFs were activated by IL-27 alone, or in combination with other cytokines. CXCL10 synthesis was measured by real-time PCR and ELISA. An examination of transcriptional regulation was performed via the transient transfection of promoter constructs, whereas mRNA stability was assessed by actinomycin D chase and real-time PCR...

Pneumocystis colonization has been associated with airway inflammation and obstruction. We conducted a retrospective cohort study to investigate the clinical significance of Pneumocystis in the airway of patients with active tuberculosis. Of the 108 respiratory specimens tested positive for M. tuberculosis by polymerase chain reaction (PCR), 11 (10.2%) were also positive for Pneumocystis by PCR. Compared with patients tested negative for Pneumocystis, those with Pneumocystis had a higher serum alanine transaminase level, a greater likelihood of requiring oxygen supplementation, and a worse 30-day mortality...

BACKGROUND/OBJECTIVE: Respiratory infections including atypical bacteria Mycoplasma pneumoniae (Mp) contribute to the pathobiology of asthma and chronic obstructive pulmonary disease (COPD). Mp infection mainly targets airway epithelium and activates various signaling pathways such as nuclear factor κB (NF-κB). We have shown that short palate, lung, and nasal epithelium clone 1 (SPLUNC1) serves as a novel host defense protein and is up-regulated upon Mp infection through NF-κB activation in cultured human and mouse primary airway epithelial cells...
