Prevalence, patterns, characteristics and challenges in management of multi-drug resistant tuberulosis cases under...

Area of Science:

• Public Health
• Infectious Diseases
• Tuberculosis Research

Background:

• The Revised National Tuberculosis Control Programme (RNTCP) has achieved success in tuberculosis control in India.
• However, drug-resistant tuberculosis (MDR-TB) remains a significant public health challenge.
• This study investigates MDR-TB prevalence, drug resistance patterns, and patient characteristics in Amritsar, Punjab, alongside challenges in DOTS-PLUS implementation.

Purpose of the Study:

• To determine the prevalence of multidrug-resistant tuberculosis (MDR-TB).
• To analyze drug resistance patterns among tuberculosis patients.
• To identify characteristics of MDR-TB patients and challenges in DOTS-PLUS program implementation.

Main Methods:

• A retrospective study was conducted analyzing patient records from November 2011 to April 2013.
• Data included MDR-TB suspects identified according to RNTCP criteria.
• Patient treatment initiation for Category IV regimens was assessed.

Main Results:

• Prevalence of drug resistance was 22.50% in Category I failures and 36.25% in Category II patients positive at the fourth month or later.
• Out of 67 identified MDR-TB cases eligible for Category IV treatment (resistant to H and R, or R), 55 were initiated on treatment.
• The average time from MDR-TB case identification to Category IV regimen initiation was 17.89 days.

Conclusions:

• Early referral, rapid diagnosis, and prompt initiation of Category IV treatment are essential for managing MDR-TB.
• These interventions are critical to reduce morbidity, mortality, and transmission of multidrug-resistant tuberculosis.
• Addressing challenges in DOTS-PLUS implementation is vital for effective MDR-TB control.
