INTRODUCTION

Tuberculosis (TB) remains a major public health challenge worldwide, necessitating updated guidelines to enhance case detection, treatment, and prevention. The 2024 National Tuberculosis Guidelines provide a structured approach to TB case management, ensuring improved patient outcomes while adhering to global best practices. This article presents a crisp and structured overview of the latest TB guidelines, offering healthcare professionals and policymakers a quick yet comprehensive reference.

1. Introduction to TB Case Management

TB case management involves the detection, diagnosis, treatment, and follow-up of TB patients. The 2024 guidelines prioritize early diagnosis, patient-centered care, and improved treatment adherence.

Key Objectives:

• Strengthen diagnostic services with rapid molecular testing.
• Improve treatment adherence through patient-centered approaches.
• Enhance TB preventive strategies.
• Integrate digital tools for case management and surveillance.

2. TB Diagnosis and Screening

2.1 Who Should Be Screened?

Screening is recommended for:

• Individuals with persistent cough (>2 weeks), weight loss, fever, or night sweats.
• High-risk populations: HIV-positive individuals, healthcare workers, prisoners, diabetics, and immunocompromised patients.
• Household contacts of confirmed TB cases.

2.2 Diagnostic Tools

The 2024 guidelines emphasize molecular testing as the primary diagnostic tool.

• GeneXpert MTB/RIF – First-line rapid molecular test.
• Line Probe Assay (LPA) – For drug resistance testing.
• Culture and Drug Sensitivity Testing (DST) – Gold standard for complex cases.
• Chest X-ray & Tuberculin Skin Test (TST) – Supplementary tools for special cases.

3. TB Treatment Guidelines

3.1 Drug-Sensitive TB (DS-TB) Treatment

• Standard 6-month regimen:
  • Intensive phase (2 months): Isoniazid (H), Rifampicin (R), Pyrazinamide (Z), and Ethambutol (E) (HRZE).
  • Continuation phase (4 months): Isoniazid (H) and Rifampicin (R) (HR).

3.2 Drug-Resistant TB (DR-TB) Treatment

The 2024 guidelines prioritize all-oral shorter treatment regimens for multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB).

• MDR-TB: 6-9 months Bedaquiline-based regimens.
• XDR-TB: Tailored all-oral regimens with Delamanid, Pretomanid, and Bedaquiline.
• Monitoring: Monthly sputum testing & clinical assessment.

4. TB Preventive Therapy (TPT)

Preventive therapy is essential in stopping TB progression, especially in high-risk groups.

• First-line preventive therapy: 3HP (Isoniazid + Rifapentine for 3 months).
• Alternative regimens: 6H (Isoniazid for 6 months) or 1HP (Isoniazid + Rifapentine for 1 month).
• Eligibility: Household contacts, HIV-positive individuals, immunosuppressed patients.

5. TB Case Management and Patient Support

5.1 Patient-Centered Care Approach

• Counseling & Education: Ensuring treatment adherence.
• Nutritional Support: Addressing malnutrition to improve recovery.
• Psychosocial Support: Managing mental health challenges.

5.2 Adherence Monitoring & Digital Health

• 99DOTS, VOT (Video Observed Therapy): Digital tools for tracking medication adherence.
• Electronic TB Registries: Improved tracking and reporting.

6. TB Surveillance & Programmatic Management

6.1 Strengthening TB Notification

• Mandatory notification of TB cases in all settings.
• Private sector engagement to improve case reporting.

6.2 Drug-Resistance Monitoring & Supply Chain Management

• Continuous surveillance for emerging drug-resistant strains.
• Uninterrupted drug supply to prevent stockouts.

7. Special Considerations in TB Management

7.1 TB & HIV Co-Infection

• Routine HIV testing for TB patients.
• Antiretroviral therapy (ART) initiation within 2 weeks of TB treatment.
• Co-trimoxazole preventive therapy (CPT) for opportunistic infection prevention.

7.2 Pediatric TB

• Shorter pediatric-friendly regimens.
• Improved dosing accuracy using fixed-dose combinations.

7.3 TB in Pregnant Women

• Safe first-line TB treatment during pregnancy.
• Bedaquiline & Delamanid safety evaluations for DR-TB cases.

8. Future Directions & Recommendations

• Scaling up GeneXpert testing for early detection.
• Integration of AI-based diagnostics.
• Public-private partnerships for better TB control.
• Community engagement programs for awareness and stigma reduction.

Conclusion

The 2024 National Tuberculosis Guidelines emphasize rapid diagnosis, effective treatment, and robust surveillance. By leveraging innovative digital health tools, patient-centered approaches, and preventive therapy, TB management is set to improve significantly. A coordinated effort from healthcare providers, policymakers, and communities is crucial to achieving TB elimination goals.
