Drug-resistant tuberculosis in the 1990s

W W Yew¹, C H Chau

¹Tuberculosis & Chest Unit, Grantham Hospital, Aberdeen, Hong Kong.

The European Respiratory Journal

|July 1, 1995

Summary

Tuberculosis is surging globally, with alarming rates of drug resistance, especially multidrug-resistant strains. Effective control requires new treatments and robust national programs to prevent resistance and ensure patient compliance.

Background:

Global resurgence of tuberculosis (TB) in the last decade.
Alarming rise in drug-resistant TB, particularly multidrug-resistant strains of Mycobacterium tuberculosis.
Nosocomial and healthcare-associated outbreaks of multidrug-resistant TB in the USA and Europe.

Purpose of the Study:

Highlight the impact of factors like HIV, poverty, and noncompliance on TB drug resistance.
Emphasize the urgent need for rapid drug susceptibility tests and effective chemotherapy regimens.
Advocate for preventative measures and robust national TB control programs.

Main Methods:

Literature review and synthesis of current trends in tuberculosis epidemiology and drug resistance.
Analysis of contributing factors to the rise of drug-resistant TB.
Evaluation of current and proposed therapeutic and control strategies.

Main Results:

Multidrug-resistant tuberculosis poses a significant global health threat.
Noncompliance, often linked to HIV, poverty, and substance abuse, is a key driver of drug resistance.
Existing control strategies are insufficient to curb the epidemic.

Conclusions:

Urgent need for novel therapeutic strategies, including new drugs and combination therapies.
Development and implementation of rapid drug susceptibility tests are critical.
Strengthening national tuberculosis control programs with a focus on short-course chemotherapy and ensuring patient compliance is essential to combat TB resurgence and drug resistance.
