Abstract

Introduction: Worldwide tuberculosis is most common infectious cause of death. India bears one-fourth
of the global tuberculosis burden. Despite all national & international efforts to control & eliminate
tuberculosis, more than 10 million active tuberculosis cases occur each year. The problem of tuberculosis
has been further compounded by the emergence of multi drug resistant (MDR) and extensively drug
resistant(XDR) tuberculosis. Previously treated tuberculosis is most important risk factor for drug resistant
TB but treatment na¨?ve patients are also at risk due to transmission of drug resistant strain or spontaneous
mutation.
Materials and Methods: Study was conducted in Department Of Respiratory Medicine, GMC Nagpur
between May 2017 to October 2018.It was prospective observational study. All sputum smear positive cases
were subjected to mycobacterial culture and LPA testing in IRL.
Results: Total 250 patients whose sputum smear was positive for acid fast bacilli were included in study.
Maximum patients were in age group of 18-30 years of age with mean age 36.43+/-14.05.Out of 250 patient
188 were males and 62 were females. Isoniazid monoresistance was found in 6 patients and isoniazid with
rifampicin resistance was found in 9 patients.We did not find any case of rifampicin monoresistance in our
study.
Conclusion: Prevalence of isoniazid monoresistance was 2.4 % in our study while prevalence of isoniazid
and rifampicin resistance (MDR TB) was 3.6%. Thus prevalence of drug resistant TB is low amongst newly
diagnosed sputum smear positive cases. This shows success of tuberculosis control programme.

Keywords: multidrug resistant extensively drug resistant isoniazid monoresistance India.
