Intensified Tuberculosis Treatment to Reduce the Mortality of Patients With Tuberculous Meningitis (INTENSE-TBM)
Tuberculous Meningitis
About this trial
This is an interventional treatment trial for Tuberculous Meningitis focused on measuring Tuberculous Meningitis, Intensified treatment, High dose Rifampicin, Linezolid, Aspirin, Subsaharan Africa
Eligibility Criteria
Inclusion criteria:
- Age ≥ 15 years
- TBM defined as "definite", "probable" or "possible"
Signed Informed Consent
- Definite TBM = at least one of the following criteria: acid-fast bacilli seen in CSF microscopy, positive CSF M. tuberculosis culture, or positive CSF M. tuberculosis commercial nucleic acid amplification test.
- Probable TBM = total modified Marais score ≥12 when neuroimaging is available, or ≥10 when neuroimaging is not available (at least 2 points should come from CSF or cerebral imaging criteria).
- Possible TBM = total modified Marais 6-11 when neuroimaging is available, or 6-9 when neuroimaging is not available.
Exclusion criteria:
- > 5 days of TB treatment
- Renal failure (eGFR<30 ml/min, CKD-EPI formula).
- Neutrophil count < 0.6 x 109/L.
- Hemoglobin concentration < 8 g/dL.
- Total bilirubin > 2.6 times the Upper Limit of Normal
- Platelet count < 50 x 109/L.
- ALT > 5 times the Upper Limit of Normal.
- Clinical evidence of liver failure or decompensated cirrhosis.
- For women: more than 17 weeks pregnancy or breastfeeding.
- For patients without decrease level of consciousness (Glasgow Coma Scale = 15): Peripheral neuropathy scoring Grade 3 or above on the Brief Peripheral Neuropathy Score (BPNS).
- Documented M. tuberculosis resistance to rifampicin.
- Positive gram-stain, bacterial culture or cryptococcal antigen in the Cerebral Spinal Fluid.
- Evidence of active bleeding (hemoptysis, gastrointestinal bleeding, hematuria, intracranial bleeding).
- Inability to collect Cerebral Spinal Fluid, except for patients with confirmed tuberculosis (by rapid molecular test or culture) from another biological sample and clinical and/or CT scan evidence of meningitis.
- Major surgery within the last two weeks prior to inclusion.
- Ongoing chronic aspirin treatment (eg for cardiovascular risk).
- Current use of drugs contraindicated with study drugs and that cannot be safely stopped (see Appendix 1: Drugs contra-indicated with study drugs).
In available history from patients:
- Evidence of past intracranial bleeding.
- Evidence of past of peptic ulceration.
- Evidence of recent (< 3 month) gastrointestinal bleeding.
- Known hypersensitivity contraindicating the use of study drugs .
- Evidence of porphyria.
- Evidence of hyperuricemia or gout.
- Any reason which at the discretion of the investigator would compromise safety and cooperation in the trial.
