Histoplasma capsulatum is a saprophytic fungus that in immunocompetent individuals causes self-limited pulmonary infection; however, in immunosuppressed patients involvement of the reticuloendothelial system, alimentary tract, urinary tract, and central nervous system is fairly common. Rarely patients present with bilateral adrenal masses which mimic tuberculosis and metastasis on radiology because of associated central necrosis. Ultrasound guided FNAC aided by special stains like Periodic Acid Schiff (PAS) and Gomori Methenamine Silver (GMS) may help in early diagnosis in such dubious cases...

Type 2 diabetes mellitus (DM) is a major risk factor for the development of active pulmonary tuberculosis, with development of DM pandemic in countries where tuberculosis (TB) is also endemic. Understanding the impact of DM on TB and the determinants of co-morbidity is essential in responding to this growing public health problem with improved therapeutic approaches. Despite the clinical and public health significance posed by the dual burden of TB and DM, little is known about the immunological and biochemical mechanisms of susceptibility...

BACKGROUND: The impact of tuberculosis (TB) is exacerbated in Africa because of the human immunodeficiency virus (HIV) pandemic. Pulmonary tuberculosis (PTB) diagnosis is difficult in HIV-infected patients and negative sputum results are more common which leads to diagnostic delay and increases morbidity and mortality. Extra-pulmonary samples such as stool may be easier to obtain and our approach may therefore significantly improve PTB detection in people living with HIV. OBJECTIVE: To detect Mycobacterium tuberculosis from the stool of HIV sero-positive individuals suspected of pulmonary TB...

In resource-limited countries, the diagnosis of pulmonary tuberculosis (TB) is based on clinical findings, chest radiography and the demonstration of acid-fast bacilli in sputum. Few data are available on the use of ultrasound (US) to diagnose pulmonary TB. Chest US was performed in patients with lung TB from a rural African setting, to look for signs of the disease and to clarify the role US may have in the diagnosis of pulmonary TB. Sixty adult patients diagnosed with lung TB underwent chest US. All patients had abnormal findings...

Genitourinary Tuberculosis (GUTB) is the second most common extra-pulmonary manifestation of tuberculosis (Tb) and an isolated involvement of genital organs is reported in 5-30% of the cases. Genital involvement results from primary reactivation of latent bacilli either in the epididymis or the prostate or by secondary spread from the already infected urinary organs. The epididymis are the commonest involved organs affected primarily by a hematogenous mode of spread. Tb is characterized by extensive destruction and fibrosis, thus an early diagnosis may prevent function and organ loss...

BsmI (rs1544410) polymorphism located in intron 8 at the 3' end of the VDR gene is known to be involved in the regulation of mRNA stability. Many studies evaluated the possible correlation between VDR Bsm I polymorphism and the risk of pulmonary tuberculosis (PTB), and reported conflicting results. In this study, an updated meta-analysis was performed to evaluate the above said association. PubMed, EMBASE, and Google Scholar web-databases were searched for the relevant studies and a meta-analysis was performed by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for all the genetic models...

Tuberculous involvement of the spinal cord parenchyma is an exceedingly rare clinical entity; even more so is concurrent intracranial tuberculosis (TB). Spinal intramedullary TB presents with a characteristic subacute myelopathy, with slowly progressive paraplegia, sensory deficits, and/or bowel and bladder dysfunction. Diagnosis is strongly suspected with a clinical history of known TB in conjunction with characteristic findings on magnetic resonance imaging. Management involves multi-agent antitubercular chemotherapy without or with operative intervention...

Bacillus Calmette-Guérin (BCG) is the only available vaccine against tuberculosis. Although its protective efficacy against pulmonary tuberculosis is still under debate, it provides protection against other mycobacterial diseases. BCG is also an effective therapy against superficial bladder cancer and potentially decreases overall childhood mortality. Areas covered. The purpose of this paper is to provide a state-of-the-art summary of the beneficial effects of BCG in inflammatory and auto-immune diseases. As a strong inducer of Th1 type immunity, BCG has been reported to protect against atopic conditions, such as allergic asthma, a Th2-driven disorder...

Currently available Interferon-γ release assay (IGRA) cannot reliably differentiate active TB (ATB) from non-active TB (non-ATB). A study was performed to evaluate the value of Mycobacterium tuberculosis (MTB) specific Th1 cell immune responses which test IFN-γ and IL-2 simultaneous for differentiating ATB from non-ATB. Forty-nine newly diagnosed inpatients with ATB (26 pulmonary TB and 23 extrapulmonary TB) were enrolled as the ATB group. Forty-five volunteers with latent tuberculosis infection (LTBI) and twenty with evidence of previous TB were enrolled during the same period as the non-ATB group...

BACKGROUND: Hepcidin is a 25-amino acid peptide produced by the liver in response to inflammation and iron overload. It is encoded by the hepcidin antimicrobial peptide (HAMP) gene and plays a key role in innate immunity. Previous studies have reported that a -582 A>G polymorphism in the HAMP promoter (HAMP-P) affects hepcidin expression, causing susceptibility to various bacterial and viral pathogens. However, it is not known whether the HAMP-P -582 A>G polymorphism is associated with tuberculosis (TB) susceptibility...
