Summary

Tuberculosis drug toxicity was studied in 47 patients. 15% experienced adverse events, with 8.5% requiring drug withdrawal due to severe reactions like hepatitis and hypersensitivity.

Area of Science:

  • Pharmacology and Toxicology
  • Infectious Diseases
  • Hepatology

Background:

  • Tuberculosis (TB) treatment relies on combination anti-TB drugs.
  • Understanding drug-induced toxicity is crucial for patient safety and treatment adherence.
  • Hepatotoxicity is a significant concern with anti-TB regimens.

Purpose of the Study:

  • To describe the hepatotoxicity and other adverse events associated with anti-tuberculosis drug combinations.
  • To determine the incidence of drug withdrawal due to toxicity in patients undergoing TB therapy.

Main Methods:

  • Observational study of 47 patients completing 6-9 months of anti-tuberculosis therapy.
  • Monitoring and documentation of adverse events, including signs of toxicity and drug withdrawal.

Main Results:

  • Seven out of 47 patients (15%) exhibited signs of drug toxicity.
  • Four patients (8.5%) required discontinuation of anti-TB drugs.
  • Hepatitis (with jaundice or deranged liver function) and severe hypersensitivity reactions were observed.

Conclusions:

  • Combination anti-tuberculosis therapy can lead to significant hepatotoxicity and hypersensitivity reactions.
  • Close monitoring for adverse events is essential during TB treatment to manage toxicity and prevent drug withdrawal.
