Summary
Tuberculosis treatment with isoniazid in hemodialysis patients can cause cerebellar dysfunction. Supplemental pyridoxine is recommended to prevent this isoniazid-related neurotoxicity.
Area of Science:
- Nephrology
- Neurology
- Infectious Diseases
Background:
- Tuberculosis (TB) treatment requires careful management in patients with chronic kidney disease undergoing hemodialysis.
- Standard anti-TB regimens may pose unique risks in patients with renal impairment.
Observation:
- A hemodialysis patient developed acute cerebellar dysfunction during treatment with isoniazid, rifampin, and pyrazinamide.
- Symptoms resolved upon dose adjustment of isoniazid and addition of pyridoxine.
Findings:
- The observed neurotoxicity was strongly suspected to be linked to isoniazid.
- Pyridoxine supplementation may mitigate isoniazid-induced neurotoxicity in patients with renal failure.
Implications:
- Clinicians should consider routine pyridoxine supplementation for hemodialysis patients undergoing isoniazid therapy.
- This proactive measure can help prevent isoniazid-related neurotoxicity and improve patient outcomes.
