  • Sharpening India’s anti-tuberculosis fight     

    Why in the News?

    In the present context, in India, there are groundbreaking new treatments available, but we need to rethink and update the program to eliminate TB.

    Current status of TB in India: 

    • Incidence Rate: As of 2022, the incidence rate of TB in India was reported at 199 cases per 100,000 population, a decline from 237 per lakh population in 2015. This reflects a 16% decrease in new TB cases since 2015.
    • Prevalence: The estimated prevalence of tuberculosis infection (TBI) among individuals over 15 years of age was around 31% according to a national survey conducted from 2019 to 2021. 
    • Global Contribution: India accounted for approximately 26% of the global incidence of TB cases in 2020. In that year, India also represented 38% of global TB deaths among HIV-negative individuals.
    • Mortality Rate: The mortality rate due to TB decreased from 28 per lakh population in 2015 to 23 per lakh population in 2022, indicating progress in managing the disease.
    • Total Cases: Estimates suggest that the total number of TB cases in India has increased from 2.2 million to 2.6 million in recent years, reflecting ongoing challenges in detection and treatment.

    What were the problems with previous Extended Treatment Regimen?

    • Lengthy and Complex: Traditional TB treatment regimens are long and require patients to take 13 to 14 tablets daily for 9 to 11 months, or 4 to 5 tablets daily for 18 to 24 months.
    • Severe Side Effects: These regimens are physically and psychologically draining, causing side effects like loss of hearing and psychosis.
    • Economic Impact: Prolonged treatment leads to loss of employment and drives many families into poverty due to the need for frequent clinic visits.

    WHO-Recommended Effective Regimen:

    • BPaL/M Regimen: WHO has recommended a shorter, safer, and more effective regimen called BPaL/M for drug-resistant TB patients.
    • Advantages: This regimen requires only 3 to 4 tablets daily for six months, with fewer side effects and higher success rates (89% compared to 68% for traditional treatments).
      • Close to 80 countries have procured the BPaL/M regimen, and 20 high-burden countries are already rolling it out.

     

    Present TB Elimination Policy in India:

    • The deficiency in the NTP was identified in 1963 and the Revised National TB Control Programme was developed.
    • Presently, India’s National TB Elimination Programme 2023 is leading the effort to meet the goal of eliminating TB by 2025, five years ahead of the SDGs.
    • Ending the TB epidemic by 2030 is among the health targets of the UN’s Sustainable Development Goals.

    How India can make the best use of new treatments?

    • Proactive Screening and Diagnosis: Focus on modernizing health datasets, GIS mapping, and conducting targeted multi-disease screening drives, especially in vulnerable populations (e.g., those with comorbidities, slum dwellers, and prisoners).
    • Advanced Diagnostic Tools: Expand the use of portable X-ray machines with AI-driven tools and rapid molecular tests for faster and more accurate detection and drug resistance profiling.
    • Early Detection and Treatment: Leveraging new technologies and proactive measures will help improve TB detection rates, reduce delays, and enhance treatment outcomes, ultimately aiding in the elimination of TB in India.

    Conclusion: India need to invest in advanced diagnostic tools like AI-driven portable X-ray machines and rapid molecular tests to ensure early and accurate detection of TB, particularly in high-risk and underserved populations, to support timely treatment and reduce TB incidence.
