INTRODUCTION: In the 1930-50s, before the introduction of antimicrobial drugs and development of techniques of pulmonary resssection, collapse therapy was the mainstream of treatment for cavitary pulmonary tuberculosis. The methods to achieve the collapse included artificial pneumothorax with air refills, phrenic nerve crush, thoracoplasty and extrapleural plombage. The plombage involves creating a cavity surgically under the ribs in the upper chest wall and filling the space with inert material, such fat, paraffin wax, rubber ballons, oil and methyl-methacrylate (Lucite) balls...

Tuberculosis (TB) treatment regimens have been extrapolated from adults to children. However, pediatric disease merits different treatment strategies to avoid under- or over-treatment. While animal models have been pivotal in identifying effective regimens for adult disease, pediatric TB is heterogeneous and cannot be represented by a single preclinical model. Infants and young children most commonly have disseminated disease or tuberculous meningitis (TBM), school-aged children have paucibacillary disease, and adolescents have adult-like cavitary lung disease...

BACKGROUND: Although active tuberculosis (TB) is considered a contraindication for liver transplantation (LT), this is the only treatment in patients with liver failure and concurrent active TB. We report a case with successful urgent living-donor LT for irreversible liver failure in the presence of active TB. CASE PRESENTATION: A 48-year-old man, with a history of decompensated alcoholic liver cirrhosis, was presented with stupor. At admission, his consciousness had deteriorated to semi-coma, and his renal function also rapidly deteriorated to hepatorenal syndrome...

Echinococcosis is a common cause of pulmonary cavities. Aspergillus fumigatus, a saprophytic fungus, can colonise pulmonary cavities caused by tuberculosis, sarcoidosis, echinococcosis, bronchiectasis and neoplasms. Infection by Aspergillus is often seen in immunosuppressed cases. However, co-infection of Aspergillus with pulmonary echinococcosis is unexpected and very unusual, especially in an immunocompetent patient. We present the case of a 45-year-old immunocompetent male who came with non-resolving pneumonia and fever for 8 months and dyspnoea since 15 days accompanied by recurrent episodes of hemoptysis since 5 days...

In clinical trials of two rifamycin antibiotics (rifampin and rifapentine) for treating tuberculosis (TB), patients with cavitary lung lesions did not appear to derive benefit from rifapentine. Rifapentine was found not to outperform rifampin, despite a lower minimum inhibitory concentration against Mycobacterium tuberculosis in mouse models of TB. To understand these findings, we have developed a rabbit model of TB that reliably develops lung cavities with features similar to those of patients with pulmonary cavitary TB...

BACKGROUND: Cough frequency, and its duration, is a lab-free biomarker that can be used in low-resource settings and has been associated with transmission and treatment response. Radiological characteristics associated with increased cough frequency may be important in understanding transmission. The relationship between cough frequency and cavitary lung disease has never been studied. METHODS: We analyzed 41 human immunodeficiency virus-negative adults with culture-confirmed, drug-susceptible pulmonary tuberculosis throughout treatment...

Background: Cavitation is a serious consequence of tuberculosis. We tested the hypothesis that repetitive exposure to the same total bacterial burden of Mtb drives greater lung destruction than a single exposure. We also tested whether inhibition of endogenous MMP1 may inhibit cavitation during TB. Methods: Over a three weeks interval we infected rabbits with either 5 aerosols of 500 CFU of Mtb or a single aerosol of 2500 CFU plus four sham aerosols. We administered the MMP1 inhibitor cipemastat (100 mg/kg daily) from week 5-10 to a subset of the animals...

Introduction: Blastomyces dermatitidis is a dimorphic fungus endemic to the Mississippi River valley. We describe a rare case of chronic pulmonary blastomycosis complicated by large pulmonary cavitation in a young service member who was misdiagnosed with active pulmonary tuberculosis. Case Presentation: A 25-year-old active duty male presented to his primary care provider with complaints of hemoptysis, fatigue, weight loss, and fever. Computed tomography chest with contrast identified a large cavitary lesion in the right upper lobe (RUL)...

Background/Aims: Patients with diabetes mellitus (DM) and tuberculosis (TB) have increased morbidity and a high risk of treatment failure or recurrence. It is important to manage both diseases simultaneously. Among anti-diabetic drugs, metformin inhibits intracellular growth of mycobacteria. Therefore, we examined the effects of metformin on TB treatment, especially in patients with DM. Methods: This retrospective cohort study included patients with culture-positive pulmonary TB diagnosed between 2011 and 2012...

INTRODUCTION: Spontaneous pneumothorax (SP) is a frequent complication of pulmonary tuberculosis (TB) and a severe form of the disease. In spite of the fact that TB is a common cause of pneumothorax, a very few series, have been reported. METHODS: We retrospectively analysed the experience of SP secondary to TB in patients who were hospitalized in our department between 2005 and 2015. RESULTS: The mean age of patients was 38,5±19 years. Two patients had a history of pulmonary tuberculosis...

Treatment monitoring is an essential aspect for tuberculosis (TB) disease management. Sputum smear microscopy is the only available tool for monitoring, but it suffers from demerits. Therefore, we sought to evaluate markers and cellular subsets of T regulatory (Treg) cells and T helper (Th) 17 cells in pulmonary TB patients (PTB) for TB treatment monitoring. Peripheral blood mononuclear cells (PBMCs) were stimulated in vitro (with purified protein derivative (PPD)) overnight which was followed by a polychromatic flow cytometry approach to study Treg and Th17 markers and cellular subsets in PTB ( n  = 12) undergoing antituberculous treatment (ATT)...

Mycobacterium celatum is a slow-growing, non-tuberculous mycobacterium (NTM) and a rare cause of infection in humans. Infection occurs primarily by inhalation or direct inoculation from environmental sources, and this pathogen has been reported to cause localized infections in the lungs and lymph nodes of both immunocompetent and immunocompromised patients, and disseminated disease in immunocompromised patients. Here, we present a case of pulmonary infection with M. celatum in an immunocompetent 68-year-old male with clinical features similar to tuberculosis...

Background: Prior research suggests that diabetes mellitus (DM) is associated with increasing risk for developing cavitary lung disease in patients with pulmonary tuberculosis (TB). Additionally, chest computed tomography (CT) scan may be more sensitive than chest X-ray in detecting cavitary disease in such patients. The aim of this study was to compare the performance of chest CT to chest X-ray in detecting cavitary lung disease and to compare the frequency of cavities between TB patients with DM and without DM...

Hypercalcaemia occurs in many granulomatous diseases. Among them, sarcoidosis and tuberculosis are the most common causes. Other causes include berylliosis, coccidioidomycosis, histoplasmosis, Crohn's disease, silicone-induced granulomas, cat-scratch disease, Wegener's granulomatosis and Pneumocystis carinii pneumonia. Hypercalcaemia in granulomatous disease occurs as a consequence of dysregulated production of 1,25-(OH)2 D3 (calcitriol) by activated macrophages in granulomas. Hypercalcaemia in patients with Mycobacterium tuberculosis infection has been reported in 0%-28% of cases...

We performed a systematic review and meta-analyses of studies assessing tuberculosis (TB) patient-related risk factors for transmission of Mycobacterium tuberculosis infection. Meta-analyses were conducted for sputum smear-positivity, lung cavitation and HIV seropositivity of index patients with both crude and adjusted odds ratios (AORs) pooled using random effect models. Thirty-seven studies were included in the review. We found that demographic characteristics such as age and sex were not significant risk factors, while behaviours such as smoking and alcohol intake were associated with infectiousness although inconsistently...
