Sharpening India’s anti-tuberculosis fight

Tuberculosis (TB) remains a significant health issue worldwide, with India shouldering a large share of the global burden. Recent progress in TB management includes the diagnosis of 25.1 lakh TB patients in 2023, highlighting improved case-finding efforts. Despite these advancements, challenges persist in TB treatment and detection, necessitating further innovations and effective deployment of new tools.

Treatment Innovations

• Introduction of Shorter Regimens: India is set to adopt the WHO-recommended BPaL/M regimen for drug-resistant TB, which offers a shorter, six-month treatment duration compared to the current regimens that last up to 24 months.
• Benefits of BPaL/M Regimen: The BPaL/M regimen is noted for its higher efficacy, with a success rate of 89% compared to the 68% success rate of existing treatments. It requires fewer tablets per day, minimizing the physical and psychological strain on patients.
• Cost Savings: Implementing the BPaL/M regimen could lead to global savings of about $740 million annually. This new regimen is cost-effective, reducing treatment costs by 40% to 90% compared to current regimens.

Enhancing Diagnosis

• Importance of Efficient Screening: To improve TB diagnosis, health systems must modernize screening methods and leverage health datasets, including GIS mapping, to identify high-risk populations such as those with comorbidities or in vulnerable settings.
• Role of Advanced Technology: Portable X-ray machines with AI-driven tools are recommended for faster and more accurate diagnosis, especially in remote and under-resourced areas. These tools can help detect a significant portion of TB cases that would otherwise be missed.
• Shifting to Rapid Molecular Tests: Expanding the use of rapid molecular tests over traditional microscopy methods is crucial. This shift will enable quicker detection and drug resistance profiling, facilitating timely and appropriate treatment.

Strategic Approach for TB Elimination

• Proactive Case Finding: A proactive approach is necessary to reduce diagnostic delays by targeting multi-disease focused screening drives, especially for populations at higher risk or those without typical TB symptoms.
• Utilization of Data and Technology: Integrating technological advancements and comprehensive health data can significantly enhance TB detection rates and treatment outcomes. This approach will also aid in reducing delays in diagnosis.
• Investment in New Treatments and Diagnostics: Investing in innovative treatments and diagnostic tools is vital for achieving TB elimination. Prioritizing these areas will ensure a healthier future by improving detection and treatment efficacy.
