Summary

Monitoring transaminase levels is crucial for managing antitubercular drug hepatotoxicity. Chronological observation aids in determining drug discontinuation and guides treatment for patients with elevated liver enzymes.

Area of Science:

  • Hepatology
  • Pharmacology
  • Infectious Diseases

Background:

  • Antitubercular drugs can cause drug-induced liver injury (DILI).
  • Elevated transaminases are common indicators of hepatotoxicity.
  • Establishing preventive measures for DILI is essential for tuberculosis treatment.

Purpose of the Study:

  • To analyze the clinical course of antitubercular drug-induced hepatotoxicity.
  • To establish preventive measures for elevated transaminases.
  • To guide clinical decisions regarding drug management in patients with liver dysfunction.

Main Methods:

  • Retrospective study design.
  • Inclusion of 446 patients with normal liver function at admission.
  • Analysis of clinical courses and transaminase levels over time.

Main Results:

  • Over 50% of 113 patients with abnormal transaminases worsened by week 4, and 80% by week 8.
  • Initial elevated transaminase values did not correlate with recovery rates.
  • Higher peak transaminase levels and exacerbation were associated with delayed normalization.

Conclusions:

  • Chronological monitoring of transaminases is vital for managing antitubercular drug-induced hepatotoxicity.
  • Patients with severe pulmonary tuberculosis may continue chemotherapy with careful liver function monitoring, even with transaminase levels exceeding 100.
  • These findings support informed decisions on drug discontinuation or continuation based on liver enzyme trends.
