Delamanid (OPC-67683, Deltyba(TM) , nitro-dihydro-imidazooxazoles derivative) is approved for the treatment of adult pulmonary multidrug-resistant tuberculosis. The absorption, distribution, and excretion of delamanid-derived radioactivity were investigated after a single oral administration of (14) C-delamanid at 3 mg/kg to rats. In both male and female rats, radioactivity in blood and all tissues reached peak levels by 8 or 24 hours postdose, and thereafter decreased slowly. Radioactivity levels were 3- to 5-fold higher in lung tissue at time to maximum concentration compared with plasma...

Urogenital tuberculosis is the second most frequent form of extrapulmonary tuberculosis. Starting with a pulmonary focus, 2 to 20% of patients develop urogenital tuberculosis through hematogenous spread to the kidneys, prostate, and epididymis; through the descending collecting system to the ureters, bladder, and urethra; and through the ejaculatory ducts to the genital organs. Urogenital tuberculosis occurs at all age ranges, but it is predominant in males in their fourth and fifth decades. It is a serious, insidious disease, generally developing symptoms only at a late stage, which leads to a diagnostic delay with consequent urogenital organ destruction; there are reports of patients with renal failure as their initial clinical presentation...

A 66-year-old Caucasian female presented with insidious sciatic pain leading to an uncommon diagnosis of tuberculous osteomyelitis with unknown portal entry. The patient did not report a history of a previous tuberculosis (TB) infection and her chest X-ray was negative for TB. Considering TB in the differential diagnosis of a 'bone abscess', it is of paramount importance to come to a correct diagnosis. Conventional radiographs still remain the first-line imaging modality for evaluation of skeletal symptomatology...

BACKGROUND: The effects of antiretroviral therapy on risk of severe bacterial infections in people with high CD4 cell counts have not been well described. In this study, we aimed to quantify the effects of immediate versus deferred ART on the risk of severe bacterial infection in people with high CD4 cell counts in a preplanned analysis of the START trial. METHODS: The START trial was a randomised controlled trial in ART-naive HIV-positive patients with CD4 cell count of more than 500 cells per μL assigned to immediate ART or deferral until their CD4 cell counts were lower than 350 cells per μL...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) has been declared as a global emergency by the World Health Organization in 1993 and still remains one of the world's biggest threats. Worldwide, 9.6 million people have been estimated to have fallen ill with TB in 2014: 5.4 million men, 3.2 million women, and 1.0 million children. To reduce this burden, detection and treatment gaps must be addressed and new tools developed (Global TB report 2015). METHODS: Seroreactivity of the purified excretory secretory (ES) antigens ES-31, ES-43, ES-41, and ES-6 have been assessed in pulmonary TB (fresh, relapse, chronic, and latent), extrapulmonary TB, and in human immunodeficiency virus-TB coinfection...

OBJECTIVE/BACKGROUND: Molecular methods for the detection of Mycobacterium tuberculosis (MTB) are widely used for the early diagnosis of tuberculosis (TB). The objectives of this study were to evaluate the performance of two molecular techniques for the detection of MTB for both pulmonary and extrapulmonary specimens in comparison with conventional culture techniques in Kuwait and to correlate the results with clinical and histopathological diagnosis. METHODS: A total of 9,594 consecutive pulmonary (n=5,597) and extrapulmonary (n=3,997) specimens received by the Kuwait National TB Reference Laboratory from November 2011 to December 2015 were processed for direct smear microscopy for acid-fast bacilli using a Zhiel-Neelsen stain, Xpert MTB/RIF assay, ProbTec polymerase chain reaction (PCR), and growth in fully automated MGIT 960 system tubes...

Expanding tuberculosis (TB)-diagnostic services, including access to rapid tests, is a World Health Organization (WHO) strategy to accelerate progress toward ending TB. Faster and more sensitive molecular tests capable of diagnosing TB and drug-resistant TB have the technical capacity to address limitations associated with smears and cultures by increasing accuracy and shortening turnaround times as compared with those of these conventional laboratory methods. Nucleic acid amplification assays used to detect and analyze Mycobacterium tuberculosis (MTB)-complex nucleic acids can be used directly on specimens from patients suspected of having TB...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) remains the leading cause of AIDS-related deaths among adults in countries with resource limitations. The emergence of the Xpert MTB/RIF rapid molecular assay and its subsequent World Health Organization endorsement in 2010 transformed the TB-diagnostic landscape. Xpert provided diagnostic accuracy that was far superior to that of the sputum-smear microscopy test previously used. The detection of mycobacterial lipoarabinomannan (LAM) antigen in urine has emerged as a potential point-of-care test for TB...

BACKGROUND: Central nervous system (CNS) infections caused by Mycobacterium tuberculosis (MTB) are the most severe forms of extrapulmonary TB (EPTB) due to high levels of mortality and neurological morbidity. Limited studies are available on CNS-TB animal-model development, despite the steady rise in cerebral-TB cases in India over the past decade. This study describes the development of a murine model of CNS-TB using a clinical strain (C3) isolated from the cerebrospinal fluid (CSF) of CNS-TB patients...

Childhood tuberculosis (TB) has been long neglected but has gained attention in recent years. In 2012, the World Health Organization annual report included an estimate for childhood TB for the first time, and in the following year, the TB Alliance received a grant from UNITAID (International Drug Purchase Facility) to develop pediatric TB formulations. Qatar is a low-incidence country. In this observational study, laboratory-confirmed cases of TB were analyzed from 2013 to 2015 and included patients aged ⩽14years...

AIMS AND OBJECTIVES: Extrapulmonary disease accounts for a significant proportion of all cases of tuberculosis (TB) in endemic areas. With increasing prevalence of human immunodeficiency virus (HIV), the case numbers are rising; extrapulmonary involvement can be seen in >50% of patients with concurrent AIDS and TB. In both HIV-positive and HIV-negative cases, due to diagnostic difficulties, extrapulmonary disease is often recognized late and, hence, although completely curable in many cases, as far as bacterial eradication is concerned, is not without consequence...

Tuberculosis is a common infectious mycobacterial disease having a wide range of clinical and serological manifestations that are similar to rheumatic disease. Differential diagnosis is a crucial aspect in any rheumatic disease as many other infectious diseases portray clinical similarities and autoantibody positivity. Our case report illustrates of a young woman just after the delivery of a child presented an unusual case of extrapulmonary tuberculosis infection initially misdiagnosed as systemic lupus erythematosus (SLE)...

Papua New Guinea is one of the 14 highest-burden countries for tuberculosis (TB) infection, but few community-based studies exist. We evaluated a low-cost method of active community case finding in Kabwum and Wasu in Morobe Province, Papua New Guinea. Over 3 months we visited 26 villages and screened adults and children for symptoms and signs of TB. Sputum samples were examined using smear microscopy. A total of 1700 people had chronic symptoms, of which 267 were suspicious for TB on further examination. Sputum from 230 symptomatic adults yielded 97 samples that were positive for acid-fast bacilli...

INTRODUCTION: Extrapulmonary tuberculosis (EPTB) accounts for less than 6% of all tuberculosis (TB) cases in Poland, although in other countries (European in particular) this proportion is much higher. The study was undertaken to evaluate the clinical and epidemiological differences in patients hospitalized in one of Otolaryngology Departments in Poland during 36 years. MATERIAL AND METHODS: In a retrospective study, 71 patients were identified and divided into three groups according to the study period: I - 1978-1989 (30 patients, 42%), II - 1990-2001 (19 patients, 27%) and III - 2002-2013 (22 patients, 31% of all cases)...
