入排标准

性别
All

入选标准

  • •1. Age = 18 years
  • •2. Provision of written informed consent by participant or surrogate
  • •3. Clinical diagnosis of TBM: meningitis symptoms, clinical signs of meningism and antituberculous chemotherapy planned by the attending physician
  • •4. Bedside CSF glucose to plasma ratio <50%, or absolute CSF glucose <40mg/dl or 2.2 mmol/L
  • •5. Positive CSF AFB smear or Xpert MTB/ Rif or Ultra

排除标准

  • •1. Presence of jaundice or known liver cirrhosis (Due to emergent need to begin TBM therapy to reduce mortality, enrolment will not be delayed and participants will be replaced a posteriori if baseline ALT>3x ULN)
  • •2. Greater than 3 doses of TB treatment received within the previous 3 days (induction of cytochrome P450 enzymes occurs after 3-5 days of rifampicin therapy which would affect PK data)
  • •3. Discontinued TB treatment in the prior 14 days (induction of cytochrome P450 enzymes persists for up to 2-weeks after cessation of R and would make interpretation of the PK data challenging)
  • •4. Known allergy to Rifamycins, H, Z, E or study drug excipients
  • •5. Known current/previous rifampicin drug-resistant M. tuberculosis infection
  • •6. Current cryptococcal meningitis: India ink stain positive or culture positive or cryptococcal antigen positive in the absence of prior effective treatment and prophylaxis.
  • •7. Use of any drug that has a clinically relevant interaction with rifampicin or other first-line TB drugs, including ritonavir, atazanavir or darunavir (see appendix 2 for further detail)
  • •8. Cannot or unlikely to attend regular clinic visits
  • •9. Pregnancy / Breastfeeding. Women of childbearing potential must agree to use barrier contraception or abstinence for 8 weeks. Hormonal contraception is unacceptable as rifampicin induces metabolism.
  • •10. Lack of consent from participant or family member
  • •11. Known porphyria
  • •12. Known chronic renal failure with eGFR <10 ml/min
