PURPOSE: XpertMycobacterium tuberculosis/rifampicin (Xpert MTB/RIF) assay has been endorsed by the World Health Organization (WHO) for diagnosis of extrapulmonary tuberculosis (EPTB), while the sensitivity and specificity have not been fully evaluated. We aimed to evaluate the performance of Xpert MTB/RIF assay in the detection of different extrapulmonary specimens. METHODS: A total of 420 nonrespiratory specimens were detected with acid-fast bacilli (AFB) smear microscopy, solid culture, conventional drug susceptibility testing (DST) and Xpert MTB/RIF assay...

Tuberculous mastititis is a rare clinical entity and usually affects women from the Indian subcontinent. It often mimics breast carcinoma and pyogenic breast abscess. Fine needle aspiration cytology (FNAC) is a very essential diagnostic tool when other routine laboratory investigations are not helpful in reaching to the conclusion. Tuberculosis (TB) of the breast is an uncommon presentation of TB even in countries where the incidence of pulmonary and extrapulmonary TB is high. Radiological imaging is not diagnostic...

Tuberculosis (TB) remains one of the leading causes of morbidity and mortality worldwide. Extrapulmonary tuberculosis (EPTB) constitutes around 15-20% of TB cases in immunocompetent individuals. Extrapulmonary sites that are affected by TB include bones, lymph nodes, meningitis, pleura, and genitourinary tract. Whole genome sequencing has emerged as a powerful tool to map genetic diversity among Mycobacterium tuberculosis (MTB) isolates and identify the genomic signatures associated with drug resistance, pathogenesis, and disease transmission...

INTRODUCTION: Chronic immune activation due to ongoing HIV replication may lead to impaired immune responses against opportunistic infections such as tuberculosis (TB). We studied the role of HIV replication as a risk factor for incident TB after starting antiretroviral therapy (ART). METHODS: We included all HIV-positive adult patients (≥16 years) in care between 2000 and 2014 at three ART programmes in South Africa. Patients with previous TB were excluded. Missing CD4 cell counts and HIV-RNA viral loads at ART start (baseline) and during follow-up were imputed...

Tuberculosis (TB) is the second leading cause of death from infectious disease globally with its impact more dramatic in resource limited settings. Individuals with human immunodeficiency virus (HIV) infection who also develop tuberculosis represent a significant challenge to TB control. This study was carried out to determine the prevalence of TB-HIV coinfection and pattern of infection among TB patients. We also compared treatment outcome among coinfected patients with those not coinfected. A six-year retrospective review of records of patients managed at the Tuberculosis Treatment Center of the LAUTECH Teaching Hospital, South-Western Nigeria from January 2009 to December 2014 was carried out...

STUDY DESIGN: Retrospective observational study. PURPOSE: The aim of this study was to assess the distribution of age and site of infection in patients with musculoskeletal tuberculosis (TB) and determine the number of TB/human immunodeficiency virus (HIV) coinfections as well as the incidence of multidrugresistant (MDR) TB. OVERVIEW OF LITERATURE: Of all TB cases, 1%-3% show skeletal system involvement and 30% are HIV coinfected. Although the reported distribution of skeletal TB is majorly in the spine, followed by the hip, knee, and foot/ankle, the epidemiology of extrapulmonary TB and especially musculoskeletal TB remains largely unknown, particularly in areas with a high prevalence of the disease...

Extrapulmonary tuberculosis affects an isolated organ or presents secondary to pulmonary involvement. Lymph nodes are the common sites for extrapulmonary tuberculosis. Primary extrapulmonary tuberculosis involving parietal wall is an unusual presentation. Tubercular abscess of the abdominal wall perforating to large bowel has not been reported. Here, we are reporting a very rare case of anterior abdominal wall abscess of tubercular origin in a 57-year-old female patient who presented with complaints of pain in upper abdomen for four months...

In this study, we investigated the role of a matricellular protein galectin-9 (Gal-9) in pleural effusion related to tuberculosis (TB). Plasma and pleural fluid of a patient with extrapulmonary TB were analyzed for cytokine content by ELISA and Luminex. Peripheral blood mononuclear cells (PBMCs) and pleural fluid cells (PFCs) were examined for interferon-γ (IFN-γ) secretion by the enzyme-linked immunospot (ELISPOT) assay or IFN-γ ELISA, for apoptosis and necrosis by Cell Death Detection ELISA, and also underwent cell sorting...

Tuberculous meningitis (TBM) is a severe form of extrapulmonary tuberculosis. The aims of this study were to evaluate in-house molecular diagnostic protocols of DNA extraction directly from CSF samples and the targets amplified by qPCR as an accurate and fast diagnosis of TBM. One hundred CSF samples from 68 patients suspected of TBM were studied. Four DNA extraction techniques (phenol-chloroform-thiocyanate guanidine, silica thiocyanate guanidine, resin, and resin with ethanol) were compared and CSF samples were used to determine the best target (IS6110, MPB64, and hsp65 KDa) by qPCR...

INTRODUCTION: Tuberculosis (TB) of the ankle is an uncommon presentation of extrapulmonary infection. The early diagnosis of TB arthritis of the ankle is difficult because of the uncommon site, the ability of TB to mimic other disorders and, all too common, lack of awareness of about this infection in ankle joint. CASE REPORT: A 30-year-old male presented with a 1-year history of right ankle pain and swelling. He denied any history of recent infection but had had recurrent ankle pain that had been treated accordingly...

INTRODUCTION: Tuberculosis is a major health problem worldwide. Extrapulmonary tuberculosis is often secondary to some primary foci in lungs. There are reports of tuberculous osteomyelitis involving maxilla, ulna, femur, and shoulder joint but none have reported pathological fracture in humeral diaphysis due to tuberculosis osteomyelitis without shoulder joint involvement. We report a case of pathological fracture of humerus diaphysis due to tuberculous osteomyelitis with normal articular space...

BACKGROUND: Infectious and malignant events are responsible for morbidity and mortality in patients with Immune-Mediated Inflammatory Diseases (IMIDs). Anti-tumor necrosis factor (Anti-TNF) agents appear to have an impact, however the individual effect of these agents in the different conditions is still unclear. OBJECTIVE: The goal of this study is to estimate the Incidence Rates (IR) of infections and malignancies in patients treated with anti-TNFs across different IMIDs, as well as potential risk factors...

In 2014, an estimated 1.8 million people died from Mycobacterium tuberculosis (MTB); moreover, 680,000 people developed multidrug-resistant TB (MDR-TB). Currently available anti-MDR and XDR regimens are long-lasting and expensive, need high adherence and are undermined by a high frequency of adverse drug events, thus leading to a low success rate; moreover, in the last 50 years only two new molecules, bedaquiline (BDQ) and delamanid, have been approved and released for treatment of MDR-TB. BDQ is a diarylquinoline anti-mycobacterial drug, active regardless the state of MTB; in fact, its efficacy is conserved against replicating and non-replicating bacilli, despite extracellular or intracellular location...

Peritoneal tuberculosis was diagnosed in a 38-year-old man from Curaçao, a 42-year-old Dutch man and a 38-year-old woman from Surinam. All patients had been living in the Netherlands for over a decade at the time of diagnosis. Time to diagnosis and treatment varied between patients. Factors contributing to delayed diagnosis were nonspecific symptoms, failure to consider tuberculosis exposure, consulting of more than one physician and delay in obtaining adequate material for histopathologic and microbiologic tests...

Tuberculous pleurisy (PLTB) is a common form of extrapulmonary tuberculosis. It often resolves without chemotherapy being hence considered a rather benign manifestation of the disease. Patients with PLTB mount an effective anti-mycobacterial response, unlike those with active pulmonary TB (pTB) that were shown to present an imbalance in plasma immune and endocrine mediators. In this work, we explored whether expression of the active isoform of the glucocorticoid receptor (hGRα) in the context of the inflammatory-anti-inflammatory responses of TB patients may be associated to microRNA levels...

OBJECTIVES: T-SPOT.TB is a promising diagnosis tool to identify both pulmonary tuberculosis and extrapulmonary tuberculosis, as well as latent tuberculosis; however, the factors that affect the results of T-SPOT.TB remains unclear. In this study, we aim to figure out the risk factor of T-SPOT.TB for active TB. METHODS: A total of 349 patients were recruited between January 1st, 2016 and January 22st, 2017 at Renmin Hospital of Wuhan University, including 98 subjects with TB and 251 subjects with non-TB disease, and received T-SPOT...

(18)F-fluorodeoxyglucose positron emission/computed tomography ((18)F-FDG PET/CT) imaging, an established procedure for evaluation of malignancy, reports an increased (18)F-FDG uptake in acute or chronic inflammatory condition. Lymph node tuberculosis (LNTB) is the most common form of extrapulmonary tuberculosis. However, the absence of clinical symptoms and bacteriological basis makes it difficult to diagnose. In the current case report, two patients with LNTB mimicking malignant lymphoma are presented by (18)F-FDG PET/CT...
