Central nervous system (CNS) tuberculosis should be considered in patients from endemic nations with worsening neurological symptoms. If imaging reveals possible CNS tuberculomas, potentially life-threatening lesions should be excised and analyzed. When disease is less severe, other tissues possibly infected should be biopsied first for diagnosis to avoid neurosurgery.

INTRODUCTION: Central nervous system tuberculosis (CNS-TB) is a devastating manifestation of TB. The most common form of CNS-TB is tuberculous meningitis (TBM). Drug-resistant TB poses a major threat to the control of TB worldwide. Timely treatment dramatically improves the outcome. Colorimetric techniques based on oxidation-reduction principle for drug susceptibility testing gives results quick and less expensive. OBJECTIVE: The objectives were to compare four first-line drugs' susceptibility of Mycobacterium tuberculosis isolated from cerebrospinal fluid by Mycobacteria growth indicator tube (MGIT) and resazurin assay (RA), also to estimate the minimum inhibitory concentration values by RA...

Levofloxacin is a widely used fluoroquinolone, mainly as a respiratory antimicrobial agent. It is employed as a second line therapeutic modality in pulmonary tuberculosis as well. The drug has been in use for ages, and is known to be both efficacious and safe. However, it is not free of adverse effects. The most dangerous ones are those involving the Central Nervous System (CNS). Although rare, levofloxacin can cause involuntary movements like chorea and myoclonus. Here by, we present a case of an elderly male patient who developed reversible myoclonus/chorea after a course of levofloxacin (which was initiated as part of his anti-tubercular therapy) following the development of peripheral neuropathy secondary to isoniazid...

OBJECTIVES: CNS infections like meningitis and encephalitis pose enormous healthcare challenges due to mortality, sequelae and socioeconomic burden. In tertiary setting, clinical, microbiological, cytological and radiological investigations are not distinctive enough for diagnosing microbial etiology. Molecular diagnostics is filling this gap. We evaluated the clinical impact of a commercially available multiplex molecular diagnostic system - SES for diagnosing suspected CNS infections...

BACKGROUND: Tuberculosis (TB) has been the scourge of the human race for many decades, claiming countless number of lives along the way. This is further complicated by the ability of Mycobacterium tuberculosis (M.tb) to infect extra-pulmonary sites, more specifically the brain. These forms of TB are difficult to treat due to the problems associated with drug delivery across the blood brain barrier (BBB). Linezolid (LZD and clofazimine (CFZ) are two of the more promising anti-TB antibiotics in recent times...

Central nervous system (CNS) tuberculosis (TB) is a rare but catastrophic event in patients with systemic lupus erythematosus (SLE). Here we report a case of cerebral TB in a patient with lupus myocarditis and nephritis, following cyclophosphamide immunosuppression. To our knowledge this is the first reported case of cerebral TB in SLE in a non-endemic country. A 31-year-old female with SLE and a history of regular travel to Kenya presented to our centre with clinical features of acute heart failure. She was diagnosed with severe lupus myocarditis, and a renal biopsy also confirmed lupus nephritis...

AIMS: Specific genotypes of Mycobacterium tuberculosis (MTB) have been reported to cause outbreaks of pulmonary tuberculosis (TB) in geographical areas that are endemic to TB. However, since there is little epidemiological evidence on the association of particular genotypes that cause tuberculous meningitis (TBM), we sought to investigate the association of specific MTB strains with infection of the central nervous system (CNS). MATERIALS AND METHODS: We carried out a genetic characterisation of 89 MTB isolates from TBM patients at a Southern Indian tertiary neurocare centre and compared the genotypes with strains of pulmonary TB isolated from Indian immigrants in New York City...

INTRODUCTION: Tuberculous meningitis is an infection of the meninges caused by Mycobacterium tuberculosis. It is one of the most common infectious diseases of the Central Nervous System (CNS) and a major health problem in developing countries like India. If there is delay in diagnosis and initiation of specific treatment, it causes significant morbidity and mortality. CSF-ADA 10 U/l is the standard cut off value that is used for differentiation between Tuberculous (TBM) and Non-Tuberculous Meningitis (non-TBM)...

INTRODUCTION: Tuberculous Meningitis (TBM) is the most severe form of Central Nervous System Tuberculosis (CNS-TB) and constitutes about 6% of all Extrapulmonary TB (EPTB) cases. Most guidelines for the diagnosis and management of TBM agree on the use of simple Cerebrospinal Fluid (CSF) analysis using molecular tools like Polymerase Chain Reaction (PCR). However, the sensitivity of PCR varies while using a CSF sample. In the present study, we have compared the diagnostic utility of PCR assay in both peripheral blood and CSF sample collected from TBM cases...

There is currently no convenient way to effectively evaluate whether a miliary tuberculosis patient is complicated with central nervous system (CNS) tuberculosis. We aimed to find such a way by analyzing the clinical data of these patients. Fifty patients with confirmed miliary tuberculosis and 31 patients with confirmed miliary tuberculosis complicated with CNS tuberculosis from 2010 to 2014 were selected. Their general conditions, clinical features and laboratory tests were analyzed. Factors that were significantly different between them were chosen to performed multivariate and univariate logistic regression analyses, and factors with significant P values were used to establish a scoring system...

Central nervous system (CNS) tuberculosis commonly manifests as tubercular meningitis. CNS tuberculomas are more common intracranially and less frequently involve the spinal cord. Combination of intramedullary with intracranial tuberculomas is extremely rare. We report a case of concurrent occurrence of intramedullary tuberculoma with multiple intracranial tuberculomas in a young 16-year-old boy, who presented with two weeks history of paresthesias and weakness of the lower limbs and diminution of vision in left eye, who had been treated for pulmonary tuberculosis...

INTRODUCTION: Tuberculous meningitis remains a major health issue in the community affecting young adults of both genders predominantly from rural background. In India, the disease continues to kill 2 people every 3 min or nearly 1000 daily, according to the Tuberculosis Control Society India. Tuberculosis (TB) of central nervous system (CNS) is the most devastating form of TB. As this disease is associated with very high prevalence in young adults and will ultimately contribute to great workforce loss, we decided to assess the factors deciding the disease and its course in our patients...

BACKGROUND: Untreated, miliary tuberculosis (TB) has a mortality approaching 100%. As it is uncommon there is little specific data to guide its management. We report detailed data from a UK cohort of patients with miliary tuberculosis and the associations and predictive ability of admission blood tests with clinical outcomes. METHODS: Routinely collected demographic, clinical, blood, imaging, histopathological and microbiological data were assessed for all patients with miliary TB identified from the London TB register from 2008 to 2012 from Northwest London Hospitals NHS Trust...

Infections of the central nervous system (CNS) are often acute, with significant morbidity and mortality. Routine diagnosis of such infections is limited in developing countries and requires modern equipment in advanced laboratories that may be unavailable to a number of patients in sub-Saharan Africa. We developed a TaqMan array card (TAC) that detects multiple pathogens simultaneously from cerebrospinal fluid. The 21-pathogen CNS multiple-pathogen TAC (CNS-TAC) assay includes two parasites (Balamuthia mandrillaris and Acanthamoeba), six bacterial pathogens (Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Mycoplasma pneumoniae, Mycobacterium tuberculosis, and Bartonella), and 13 viruses (parechovirus, dengue virus, Nipah virus, varicella-zoster virus, mumps virus, measles virus, lyssavirus, herpes simplex viruses 1 and 2, Epstein-Barr virus, enterovirus, cytomegalovirus, and chikungunya virus)...

Risk assessment of central nervous system (CNS) infection patients is of key importance in predicting likely pathogens. However, data are lacking on the epidemiology globally. We performed a multicenter study to understand the burden of community-acquired CNS (CA-CNS) infections between 2012 and 2014. A total of 2583 patients with CA-CNS infections were included from 37 referral centers in 20 countries. Of these, 477 (18.5%) patients survived with sequelae and 227 (8.8%) died, and 1879 (72.7%) patients were discharged with complete cure...

The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years makes the disease a topic of universal concern. It has insidious onset and can affect virtually any organ system in the body, including the central nervous system (CNS). CNS tuberculosis (TB) is becoming more and more complex and atypical with onset of multidrug-resistant TB. Routine diagnostic techniques using serology and body tissue are time consuming and may delay the definitive management...

Central nervous system tuberculosis (CNS-TB) takes three clinical forms: meningitis (TBM), intracranial tuberculoma, and spinal arachnoiditis. TBM predominates in the western world and presents as a subacute to chronic meningitis syndrome with a prodrome of malaise, fever, and headache progressing to altered mentation and focal neurologic signs, followed by stupor, coma, and death within five to eight weeks of onset. The CSF formula typically shows a lymphocytic pleocytosis, and low glucose and high protein concentrations...

Tuberculosis of the central nervous system (CNS-TB) is a devastating complication of tuberculosis, and tumor necrosis factor (TNF) is crucial for innate immunity and controlling the infection. TNF is produced by many cell types upon activation, in particularly the myeloid and T cells during neuroinflammation. Here we used mice with TNF ablation targeted to myeloid and T cell (MT-TNF(-/-)) to assess the contribution of myeloid and T cell-derived TNF in immune responses during CNS-TB. These mice exhibited impaired innate immunity and high susceptibility to cerebral Mycobacterium tuberculosis infection, a similar phenotype to complete TNF-deficient mice...
