Active clinical trials for "Tuberculosis, Meningeal"

INTENSE-TBM is randomized controlled, phase III, multicenter, 2 x 2 factorial plan superiority trial assessing the efficacity of two interventions to reduce mortality from tuberculous meningitis (TBM) in adolescents and adults with or without HIV-infection in sub-Saharan Africa: Intensified TBM treatment with high-dose rifampicin and linezolid, compared to WHO standard TBM treatment. Aspirin, compared to not receiving aspirin. The trial will be open-label for anti-TB treatment and placebo-controlled for aspirin treatment.

The primary objective is to determine whether Leukotriene A4 hydrolase (LTA4H) genotype, defined at randomisation, determines dexamethasone's clinical effectiveness when added to the first 6-8 weeks of anti-tuberculosis treatment of TBM. The investigators will conduct a LTA4H genotype stratified, parallel group, randomised, double blind, placebo-controlled multi-centre Phase III non-inferiority trial evaluating dexamethasone versus placebo for 6-8 weeks in addition to standard anti-tuberculosis drugs. The investigators will take a hybrid trial-design approach which assumes a modest harm of dexamethasone and aims to prove non-inferiority of placebo first but also allows claiming superiority of placebo in case dexamethasone causes substantial harm. Moreover, as it is possible that harm of dexamethasone only applies to the LTA4H CC genotype, the trial will allow dropping the CT group at an interim analysis but continue randomization of the CC group. In making this assessment the investigators not only determine whether dexamethasone influences survival and the incidence of new neurological events (the primary endpoint), but also whether it influences disability assessed by the modified Rankin score 12 months after the start of treatment. The secondary objective is to investigate alternative management strategies in a subset of patients who develop drug-induced liver injury that will enable the safe continuation of rifampicin and isoniazid therapy whenever possible.

Randomized phase II clinical trial which aims to assess the impact on 3-month mortality and safety of adding adalimumab to standard treatment (anti-tuberculosis drugs and corticosteroids) in HIV patients with tuberculosis meningitis in 3 countries (Brazil, Mozambique, and Zambia).

This is a phase II randomized open-label trial of high versus standard dose rifampin (RIF) with or without linezolid (LZD) for the first 4 weeks of treatment for Tuberculosis Meningitis (TBM) at Masaka Regional Referral Hospital in Uganda. Initial randomization will be to high (35 mg/kg/day) versus standard (10 mg/kg/day) dose oral rifampin for the first 4 weeks of intensive therapy. Participants will then undergo a second randomization to linezolid 1200 mg daily versus no linezolid for the first 4 weeks of therapy. The primary aims are (1) to determine the cerebrospinal fluid and plasma pharmacokinetics of adjunctive LZD 1200 mg daily in TBM patients receiving high or standard dose RIF and (2) to evaluate the tolerability of a 4-week course of LZD in TBM patients.

The investigators will conduct a randomized, double blind, placebo controlled trial of adjunctive dexamethasone in the initial (6-8 weeks) treatment of tuberculous meningitis in Vietnamese adults. The trial will address a primary hypothesis in all enrolled patients, and a secondary hypothesis in a sub-group of enrolled patients who develop anti-tuberculosis drug-induced liver injury (DILI). The primary hypothesis is adjunctive dexamethasone increases survival from TBM in HIV co-infected adults. The secondary hypothesis is current guidelines for the management of anti-tuberculosis drug-induced liver injury in those with TBM result in the premature interruption of rifampicin and isoniazid (the critical active drugs in early therapy) and are thereby placing participants at risk of poor outcomes.

The rapid diagnosis of tuberculosis (TB) in children remains a serious challenge owing to limitations in the existing diagnostic tests. TB meningitis (TBM), an extrapulmonary form of TB, is the most severe manifestation of paediatric TB. TBM results in high morbidity and mortality in children, despite the availability of chemotherapy, mainly due to diagnostic delay. Most tests required for proper TBM diagnosis including analysis of cerebrospinal fluid (CSF) and brain imaging are not available in resource-limited settings e.g., in most of Africa including South Africa. New tests for TBM are urgently needed. The main goal of this proposal is to develop a point-of-care (POC) diagnostic test for TBM, based on CSF and bloodbiomarkers. Aim 1: Evaluate the diagnostic potentials of 51 host inflammatory biomarkers that the investigators recently identified in CSF and blood samples from children with suspected meningitis in a repository of 100 stored CSF and serum samples using a multiplex platform. After statistical analysis including multi-marker modelling by linear discriminant analysis, random forest, and other modelling techniques, the investigators will select the best combination of up to four biomarkers for incorporation into the prototype diagnostic test (Aim 2). Aim 2: Incorporate the best performing CSF and serum biomarkers into a novel, patented biosensor-based POC diagnostic test. The investigators will develop a multi-biomarker prototype test for detecting up to 4 biomarkers in serum or CSF. Aim 3: Evaluate the newly developed POC test on 300 children prospectively. This will be done at the Tygerberg Academic Hospital. The diagnostic yield of the POC test will be compared to the routine diagnostic tests.

The purpose of this study is to compare a 6-month regimen of high-dose rifampicin (RIF), high-dose isoniazid (INH), linezolid (LZD), and pyrazinamide (PZA) versus the World Health Organization (WHO) standard of care (SOC) treatment for tuberculosis meningitis (TBM).

Tuberculous meningitis (TBM) is the most lethal form of extra pulmonary tuberculosis. This devastating disease kills almost a third of its sufferers and disables a significant proportion of the survivors. TBM poses one of the most difficult diagnostic and therapeutic challenges in modern clinical practice. High-quality robust clinical trials have made a considerable contribution to the treatment of pulmonary tuberculosis in the last four decades. However, evidence from such clinical trials is lacking in TBM and the treatment remains uncertain. There is a significant variation in the choice, dose and duration of drugs between countries, institutions and clinicians. Investigators propose a multi-centric open-label clinical trial to assess the efficacy of short-course anti-TB drugs with high dose rifampicin, and moxifloxacin along with conventional anti-TB drugs and adjuvant therapy with aspirin and corticosteroids. Controls will receive standard treatment as per national guidelines for TBM. The investigators also aim to assess the safety and tolerability of high-dose Rifampicin and Moxifloxacin and the Pharmacodynamics and Pharmacokinetics parameters of ATT (Rifampicin, INH, Moxifloxacin and Pyrazinamide) in CSF between the two groups

Tubercular meningitis occurs in around 10% of those with extrapulmonary tuberculosis and is a major cause of mortality and morbidity. Inspite of effective Anti-tubercular drugs, still around 30% of patients develop complications due to arachnoiditis such as spinal tubercular radiculomyelitis, optico-chiasmatic arachnoiditis, development of new tuberculomas after starting therapy etc. which are probably immune mediated inflammatory responses due to paradoxical reaction to ATT. The management of arachnoiditis is far from satisfactory. High dose methylprednisolone, intrathecal hyaluronic acid, thalidomide have been tried in small case series and case reports. However, the results have not been satisfactory. There are two published reports of cyclophosphamide usage in TBM related vasculitis and stroke The investigators tried cyclophosphamide in four patients after consent, and found remarkable improvement in all of them. (Under peer review) In order to test this hypothesis, a randomized controlled trial is needed.

The goal of this Diagnostic accuracy study is To study sensitivity and specificity of sulcal tuberculomas in the diagnosis of tubercular meningitis and To study the correlation of imaging findings in tubercular meningitis and spinal tubercular arachnoiditis with clinical outcomes after completion of therapy Secondary objectives To study the proportion of patients having clinical or imaging features of spinal tubercular arachnoiditis To study the factors determining outcomes in patients with spinal tubercular arachnoiditis To study the treatment trends in patients with spinal tubercular arachnoiditis The investigators will include [study Population] Patients with chronic meningitis as per criteria listed below Chronic meningitis : Case definition Headache with or without fever, nuchal stiffness and systemic symptoms AND CSF suggestive of meningitis Pleocytosis (>20 cells per μL) with lymphocyte predominance (>50%) OR Protein concentration greater than age-specific normal value; especially >1•0 g/L OR Glucose concentration less than 60% of concentration in blood OR MRI suggestive of meningeal enhancement on contrast enhanced T1 sequences AND Deemed by the treating physician that the syndrome is consistent with chronic meningitis Patients who are positive for antibodies to HIV and pregnant females will also be included. Willing to undergo periodic assessment clinically and with MRI as per clinical condition demands. The sensitivity and specificity of the finding of sulcal tuberculomas will be compared to the reference standard diagnostic criteria for the diagnosis of TB meningitis.
