Abstract:
We present a patient acutely ill from severe tuberculous meningo-encephalitis, in whom acute hepatic and renal failure, due to intercurrent septic shock, precluded the administration of full systemic dosage of antituberculous drugs. Daily direct intraventricular administration of 5 mg rifampicin, via a subcutaneous Ommaya reservoir connected to a catheter placed in the right lateral cerebral ventricle, resulted in rapid improvement without neurological sequelae. Intraventricular rifampicin administration for 50 consecutive days was well-tolerated without local or systemic side-effects. In well-selected patients with severe tuberculous meningo-encephalitis, intraventricular rifampicin may safely and highly effectively be added to systemic antituberculous therapy.
Insights
Direct intraventricular administration of rifampicin safely and effectively treated severe tuberculous meningo-encephalitis in a patient unable to receive systemic drugs due to organ failure. This targeted approach offers a promising alternative therapy.
Area of Science:
- Neuroscience
- Infectious Diseases
- Pharmacology
Background:
- Tuberculous meningo-encephalitis is a severe central nervous system infection.
- Systemic antituberculous drug administration can be limited by organ failure, such as hepatic and renal impairment.
- Alternative drug delivery methods are crucial for effective treatment in complex cases.
Observation:
- A patient with severe tuberculous meningo-encephalitis developed acute hepatic and renal failure, preventing standard systemic drug therapy.
- Direct intraventricular administration of rifampicin (5 mg daily) was initiated via an Ommaya reservoir.
- The patient received intraventricular rifampicin for 50 consecutive days.
Findings:
- Intraventricular rifampicin led to rapid clinical improvement.
- The treatment was well-tolerated, with no local or systemic side-effects observed.
- The patient experienced no neurological sequelae.
Implications:
- Intraventricular rifampicin is a safe and highly effective adjunctive therapy for severe tuberculous meningo-encephalitis, particularly when systemic administration is contraindicated.
- This targeted drug delivery method can overcome systemic drug limitations in critical care settings.
- Further research into intraventricular drug delivery for CNS infections is warranted.
