INTRODUCTION: The mechanisms of mononuclear phagocyte death have been associated with the permissiveness and resistance to mycobacterial replication, but it remains unknown whether or not they help predict the risk of developing TB. OBJECTIVE: To describe the factors associated with the induction of monocyte mitochondrial and membrane damage in response to PPD as well as determine if this type of damage might predict the susceptibility of developing active tuberculosis in a cohort of household contacts (HHCs) from Medellin, Colombia from 2005 to 2008...

Elderly individuals with tuberculosis (TB) are more likely to have a non-specific clinical presentation of TB and high mortality. However, factors associated with mortality in elderly TB patients have not been extensively studied. This retrospective cohort study aimed to identify factors associated with death among elderly Taiwanese with TB. All elderly patients with TB from 2006 to 2014 in Taipei, Taiwan, were included in a study. Multiple logistic regression was used to identify the factors associated with death in elderly TB patients...

BACKGROUND: HIV-infected adults initiating antiretroviral therapy (ART) in sub-Saharan Africa continue to experience high rates of morbidity and mortality during the initial months of treatment. Observational studies in high-income and resource-limited settings indicate that HIV-infected adults with low vitamin D levels may be at increased risk of mortality, HIV disease progression, and incidence of pulmonary tuberculosis (TB). As a result, vitamin D3 supplementation may improve survival and treatment outcomes for HIV-infected adults initiating ART...

Portal vein embolization (PVE) is increasingly performed worldwide to reduce the possibility of liver failure after extended hepatectomy, by inducing future liver remnant (FLR) hypertrophy and atrophy of the liver planned for resection. The procedure is known to be very safe and to have few procedure-related complications.In this study, we described 2 elderly patients with Bismuth-Corlette type IV Klatskin tumor who underwent right trisectional PVE involving the embolization of the right portal vein, the left medial sectional portal branch, and caudate portal vein...

Tuberculosis (TB) is still a major health problem and TB hospital readmission could increase health system costs. In a retrospective study in a tertiary referral hospital for TB in Tehran, Iran, TB patients with readmission were evaluated. These TB patients in the index year who were then readmitted were compared with TB patients in the same year who were not readmitted during the follow-up period. One hundred and forty-six patients had hospital readmission within three-year follow-up with mean age of 51.6 years old of whom 78 patients (53...

Immunology is a central theme when it comes to tuberculosis (TB). The outcome of human infection with Mycobacterium tuberculosis is dependent on the ability of the immune response to clear or contain the infection. In cases where this fails, the bacterium replicates, disseminates within the host, and elicits a pathologic inflammatory response, and disease ensues. Clinical presentation of TB disease is remarkably heterogeneous, and the disease phenotype is largely dependent on host immune status. Onward transmission of M...

INTRODUCTION: Multi-drug-resistant tuberculosis (MDR-TB) has emerged as a challenge to global tuberculosis (TB) control and remains a major public health concern in many countries. Diabetes mellitus (DM) is an increasingly recognized comorbidity that can both accelerate TB disease and complicate its treatment. The aim of this study is to summarize available evidence on the association of DM and MDR-TB among TB patients and to provide a pooled estimate of risks. METHODS: All studies published in English before October 2016 will be searched using comprehensive search strings through PubMed, EMBASE, Web of Science, and WHO Global Health Library databases which have reported the association of DM and MDR-TB in adults with TB (age > =15)...

Several studies have been done in relation to recurrence of tuberculosis (TB) following completion of treatment. However, recurrence of TB is still a major problem from a public health perspective in high-burden countries, where no special attention is being given to this issue. Disease recurrence is an important indicator of the efficacy of antituberculosis treatment. The rate of recurrence is highly variable and has been estimated to range from 4.9% to 25%. This variability is not only a reflection of regional epidemiology of recurrence but differences in the definitions used by the TB control programs...

Tuberculosis (TB) causes 1.3 million deaths annually. There are 0.5 million cases of multidrug resistant TB (MDR-TB) and the number of cases is rising globally. The current status quo of the lengthy treatment duration and poor treatment outcomes associated with MDR/extensively drug-resistant TB, and those with comorbidity of TB with human immunodeficiency virus and noncommunicable diseases in sub-Saharan Africa is unacceptable. The TB drug pipeline remains sparse. New innovations for shortening the duration of therapy and improving treatment outcomes (cure and long-term functional disability due to lung damage) are urgently required...

Tuberculosis (TB) and diabetes mellitus (DM) have synergetic relationship. People with diabetes are 2-3 times at higher risk of getting active TB disease. On the other hand, TB or anti-TB treatment may cause glucose intolerance. The dual disease of DM and TB is more likely to be associated with atypical disease presentation, higher probability of treatment failure and complications. In most of the health-care delivery systems of the world, DM and TB are managed separately by two vertical health-care delivery programs in spite of clear interaction between the two diseases...

BACKGROUND: Nutritional assessment is important in patients with pulmonary nontuberculous mycobacterial (PNTM) disease. The therapeutic effect of a cholesterol-rich diet in tuberculosis (TB) patients has been demonstrated, but the role of cholesterol in PNTM disease is unclear. This study evaluated the sequential changes in nutritional markers, including cholesterol, total lymphocyte count and visceral fat volume, according to the PNTM disease course. METHODS: This was an age-, sex- and number of comorbid diseases-matched case-control analysis of 89 patients with PNTM disease and 356 controls, who were participants in a Korean national survey...

PURPOSE: The association between asthma-chronic obstructive pulmonary diseases (COPD) overlap syndrome (ACOS) and tuberculosis (TB) has yet to be studied. METHODS: The newly diagnosed TB patients (age > 20 y) treated from January 2000 to December 2008 were included (ACOS cohort, n = 10 751; non-ACOS cohort, n = 42 966). The non-ACOS cohort involved patients with confirmed absence of ACOS. We calculated incidence rate ratios (IRRs) for TB in the ACOS and non-ACOS cohorts by using poisson regression analysis...

Increasing evidence indicates that the risk of nontuberculous mycobacteria (NTM) disease is elevated in patients with rheumatoid arthritis (RA). However, the risk factors and outcomes for NTM disease among RA patients remain unclear. We conducted a case-control study and estimated odds ratios (ORs) for RA patients with NTM disease according to comorbidities and anti-rheumatic medications by using conditional logistic regression. Prior tuberculosis history (adjusted OR (aOR) =5.58, p < 0.001), hypertension (aOR = 2...

The link between chronic kidney disease (CKD) and tuberculosis (TB) has been known for more than 40 years, but the interaction between these 2 diseases is still poorly understood. Dialysis and renal transplant patients appear to be at a higher risk of TB, in part related to immunosuppression along with socioeconomic, demographic, and comorbid factors. Meanwhile, TB screening and diagnostic test performance is suboptimal in the CKD population, and there is limited evidence to guide protocols. Given the increasing prevalence of CKD in TB endemic areas, a merging of CKD and TB epidemics could have significant public health implications, especially in low- to middle-income countries such as India and China, that are experiencing rapid increases in CKD prevalence and account for more than one-third of global TB prevalence...

BACKGROUND: The rapid diagnosis of bacterium-negative pulmonary TB and extra pulmonary TB is a significant problem in clinical practice. METHODS: 466 individuals were prospectively enrolled, 247 patients with TB, 147 with non-tuberculous pulmonary disease, and 65 healthy controls. Whole blood was stimulated in vitro with rCFP10/ESAT6 antigen of Mycobacterium tuberculosis. A chemiluminescence immunoassay was used to detect the stimulated release of interferon-gamma inducible protein 10 (IP-10), and a receiver operating characteristic (ROC) curve was drawn to determine cutoff value for diagnosing TB and to evaluate the diagnostic efficacy of the IP-10 assay...
