BACKGROUND: Research has been going on to formulate diagnostic criteria for TBM. Two criteria that have been studied and validated in high TB prevalence areas are the Youssef criteria (Rule 1) and Thwaites criteria (Rule 2). In our study we aimed to compare the different features of TBM and acute bacterial meningitis. METHODS: This retrospective study was done at Northwest General Hospital & Research Centre (NWGH&RC), Peshawar, Pakistan. Patients who were clinically diagnosed with TB meningitis or bacterial meningitis at the time of presentation were included in the study...

OBJECTIVE: We validated the accuracy of host selected signature gene set using unstimulated whole blood (WB), and peripheral blood mononuclear cells (PBMC) in the diagnosis of tuberculosis (TB). METHODS: The unstimulated WB and PBMC from 1417 individuals with active pulmonary TB patients, other lung diseases and healthy participants were analyzed using real time polymerase chain reaction (RT-PCR). RESULTS: The WB cohort test demonstrates that the combination of GBP5 and KLF2 can differentiate active TB versus HC with sensitivity and specificity of 77...

Although tuberculosis (TB) remains a worldwide epidemic, isolated hepatic TB is an extremely rare entity and poorly described in the literature. Isolated hepatic TB may pose a diagnostic dilemma due to the non-specific clinical symptoms and imaging features. We present a case of a 54-year-old female with an isolated caseating granulomatous lesion at the caudate lobe of liver involving the pancreatic head.

Tuberculosis (TB) in young children differs from adult TB in that the risk of rapid progression to active TB (aTB) is higher in children than in adults. The reasons for this increased risk are not fully understood. Early differentiation remains difficult between children at risk to develop aTB from those who will remain healthy and develop a latent TB infection (LTBI). Biomarkers to differentiate aTB from LTBI in children, especially in very young children, are urgently needed. To identify M. tuberculosis-specific functional T cell subsets related to clinical manifestations in children, we enrolled 87 children exposed to M...

Mycobacteria are subdivided into three groups: the Mycobacterium tuberculosis complex, the non-tuberculous mycobacteria called NTM or MOTT (Mycobacteria Other Than Tuberculosis) and Mycobacterium leprae. Over the past few decades, the incidence of infections caused by NTM has increased world wide. The differentiation of Mycobacterium tuberculosis complex from NTM is of primary importance for infection control and choice of antimicrobial therapy. However, there is so far no report in Bangladesh about the detection of NTM and hence differentiation of MTB and NTM...

Splenic tuberculosis (TB) in the form of multiple splenic cold abscesses with perisplenic extensions is a rare disease, especially in an immunocompetent host. It demonstrates diagnostic complexity, which makes identification of the disease difficult. We report a case of an immunocompetent adult male who presented with fever, pain in the left lower chest, decreased appetite, and significant weight loss. On physical examination, he had tenderness in the left lower infra-axillary region and Traube's space dullness without palpable spleen...

The incidence of tuberculosis (TB) is rising worldwide, despite the efficacy of the BCG vaccination. Populations at greatest risk of contracting TB are migrant communities, as well as immunocompromised individuals. The diagnosis of extrapulmonary TB (EPTB) can often present as a diagnostic conundrum, due to its nonspecific and varied presentation, often mimicking inflammatory bowel disease or malignancy. We present a case of caecal TB in pregnancy, which resulted in caecal perforation, a right hemicolectomy, and severe preterm delivery...

In recent years, most of the focus on improving the quality of paediatric care in low-income countries has been on improving primary care using the Integrated Management of Childhood Illness, and improving triage and emergency treatment in hospitals aimed at reducing deaths in the first 24 hours. There has been little attention paid to improving the quality of care for children with chronic or complex diseases. Children with complicated forms of tuberculosis (TB), including central nervous system and chronic pulmonary TB, provide examples of acute and chronic multisystem paediatric illnesses that commonly present to district-level and second-level referral hospitals in low-income countries...

A biosensor based on localized surface plasmon resonance (LSPR) was developed to detect the antibody of Mycobacterium tuberculosis using the fusion protein CFP10-ESAT6 as an antigen. To explore the diagnostic potential of the biosensor for tuberculosis (TB), the fusion protein CFP10-ESAT6 was immobilized on gold nanorods (Au NRs) by chemical modification, and the functionalized Au NRs were subsequently incubated with serums collected from TB patients, non-tuberculous pulmonary disease patients or healthy individuals...

Bacteriological confirmation of Mycobacterium tuberculosis is achieved in the minority of young children with tuberculosis (TB), as specimen collection is resource-intensive and respiratory secretions are mostly paucibacillary, leading to limited sensitivity of available diagnostic tests. Although molecular tests are increasingly available globally, mycobacterial culture remains the gold standard for diagnosis and determination of drug susceptibility and is more sensitive than molecular methods for paucibacillary TB...
