Preventive treatment for latent tuberculosis from Indian perspective

Area of Science:

• Public Health
• Infectious Diseases
• Global Health

Background:

• Tuberculosis (TB) continues to cause significant morbidity and mortality worldwide.
• The increasing incidence of drug-resistant TB exacerbates the existing public health crisis.
• Low-income countries bear the brunt of the TB burden, necessitating robust detection, notification, and treatment strategies.

Purpose of the Study:

• To discuss the implications of treating latent tuberculosis infection (LTBI) within the Indian context.
• To review the adaptation of World Health Organization (WHO) guidelines for LTBI treatment in India.
• To explore strategies for TB elimination beyond current practices.

Main Methods:

• Review of existing WHO guidelines for LTBI treatment.
• Analysis of the adaptation of these guidelines into Indian national guidelines in 2021.
• Discussion of the potential impact and challenges of LTBI treatment in India.

Main Results:

• WHO has provided guidelines for LTBI treatment, aiming for future TB elimination.
• Indian guidelines for LTBI treatment were adapted in 2021, incorporating WHO recommendations.
• The long-term impact of LTBI treatment in India is yet to be determined.

Conclusions:

• Treating latent TB infection (LTBI) is a key strategy to prevent active disease and contribute to TB elimination efforts.
• The adaptation of WHO guidelines into national policies, such as in India, is crucial for implementing effective LTBI management.
• Further evaluation is needed to understand the long-term outcomes of LTBI treatment programs in specific national contexts like India.
