Tuberculous empyema in lung transplantation recipients is a rare entity, with only a handful of cases reported in the English-language literature. We are reporting a case of tuberculous empyema 3 months after uncomplicated bilateral lung transplantation. The recipient underwent video-assisted thoracic surgery for diagnosis and decortication. Both the recipient and donor lacked a history of tuberculosis or tuberculosis exposure.

BACKGROUND: Diagnosis of pulmonary (PTB) and extra-pulmonary tuberculosis (EPTB) in smear-negative patients can be difficult. We assessed retrospectively the performance of Xpert MTB/RIF system (Xpert, Cepheid) in diagnosing smear-negative tuberculosis (TB), which represents the most common form of TB in a low incidence setting. METHODS: Performance of Xpert was compared to acid-fast microscopic examination using Ziehl-Neelsen (ZN) stain in patients with culture-confirmed TB...

IFN-γ release assays (IGRAs) based on region of difference 1 (RD1) antigens have improved diagnosis of Mycobacterium tuberculosis (M. tb) infection. However, IGRAs with these antigens cannot discriminate between active tuberculosis (ATB) and latent tuberculosis infection (LTBI). M. tb heparin-binding-hemagglutinin (HBHA) induces relatively high IFN-γ responses in LTBI individuals and low responses in ATB patients, but purification of the native methylated HBHA from cultures of M. tb for immunological tests is complex and time-consuming...

An 80-year-old man developed dysarthria, quadriplegia, sensory disturbance and ataxia in all limbs. Brain and spinal magnetic resonance imaging (MRI) revealed multiple enhanced lesions. Cerebrospinal fluid (CSF) levels of adenosine deaminase (ADA) remarkably elevated. Tuberculosis DNA was not detected, and tuberculosis was not cultured either in the CSF. Brain biopsy revealed the inflammatory demyelinating lesions. With the diagnosis of multiple sclerosis, corticosteroid therapy resulted in rapid improvement of his symptoms and MRI abnormalities...

BACKGROUND: In the European Union and European Economic Area only 38% of multidrug-resistant tuberculosis patients notified in 2011 completed treatment successfully at 24 months' evaluation. Socio-economic factors and patient factors such as demographic characteristics, behaviour and attitudes are associated with treatment outcomes. Characteristics of healthcare systems also affect health outcomes. This study was conducted to identify and better understand the contribution of health system components to successful treatment of multidrug-resistant tuberculosis...

Although tuberculosis (TB) is a curable disease, it continues to be one of the leading infections associated with death in the world. Extra-pulmonary TB (EPTB) occurs in approximately 10% of the total cases, presenting with lymph nodes, pleura, bone and genitourinary tract as the most common locations. Genitourinary tuberculosis, the second most common EPTB, is very difficult to diagnose unless there is a high index of suspicion. Isolated TB orchitis or prostatitis without clinical evidence of renal involvement is a rare entity among genitourinary tuberculosis...

Chronic necrotizing pulmonary aspergillosis (CNPA), a form of chronic pulmonary aspergillosis (CPA), affects immunocompetent or mildly immunocompromised persons with underlying pulmonary disease. These conditions are associated with high morbidity and mortality and often require long-term antifungal treatment. The long-term prognosis for patients with CNPA and the potential complications of CNPA have not been well documented. The aim of this study was to review published papers that report cases of CNPA complications and to highlight risk factors for development of CNPA...

Tuberculosis (TB) has severely threatened public health via emerging multidrug-resistant (MDR) and extensively drug-resistant (XDR) Mycobacterium tuberculosis (MTB) strains. For effective TB treatment, rapid, accurate, and multiplex detection of drug resistance is extremely important. However, conventional methods for TB diagnosis are time consuming and have a limited effect on treatment. Nucleic acid-based molecular detection methods have been developed as an effective MDR/XDR-TB diagnosis technology. Among the nucleic acid-based methods, ligation-dependent methods are attractive as MDR/XDR-MTB detection technologies, but multiplex analysis is limited by the detection method...

Congenital tuberculosis is rare, even where tuberculosis (TB) is endemic. A 14-day-old girl presented with a 3-day history of fever and respiratory distress. Her mother was diagnosed with a disseminated TB infection immediately after the delivery which was confirmed by a positive TB-polymerase chain reaction (TB-PCR) and subsequent culture from ascites and sputum. The infant was separated from her mother at birth. Her chest radiograph showed bilateral miliary nodules. Congenital TB was strongly suspected because of the symptoms, signs and maternal TB history, and was confirmed by TB-PCR and culture from the gastric lavage...

Tuberculosis (TB) remains a major health problem, affecting approximately one-third of the world׳s population. The tubercle bacillus can affect virtually any organ of the human body and if left untreated can lead to severe morbidity and death. Diagnosis of active TB is challenging, especially in children. As a "great imitator," the disease can mimic numerous other pathologies, both clinically and at imaging. Although recognition of active TB is crucial to initiate adequate treatment in a timely fashion, thereby preventing transmission of disease, differentiation of active and quiescent disease is not always straightforward...

Immunoglobulin G (IgG) based tests for the diagnosis of active tuberculosis (TB) disease often show a lack of specificity in TB endemic regions, which is mainly due to a high background prevalence of LTBI. Here, we investigated the combined performance of the responses of different Ig classes to selected mycobacterial antigens in primary healthcare clinic attendees with signs and symptoms suggestive of TB. The sensitivity and specificity of IgA, IgG and/or IgM to LAM and 7 mycobacterial protein antigens (ESAT-6, Tpx, PstS1, AlaDH, MPT64, 16kDa and 19kDa) and 2 antigen combinations (TUB, TB-LTBI) in the plasma of 63 individuals who underwent diagnostic work-up for TB after presenting with symptoms and signs compatible with possible active TB were evaluated...
