Pattern of rifampicin resistance and gene xpert based molecular typing of tuberculosis patients in tertiary care hospitals

Pak J Pharm Sci. 2022 Nov;35(6(Special)):1719-1724.

Abstract

Mycobacterium tuberculosis associated morbidity, mortality and drug resistance is a global health issue. The Gene Xpert is used for early diagnosis of TB and simultaneous detection of Rifampicin (RIF) resistance. We aimed to determine situation analysis of clinical TB in tertiary care hospitals of Faisalabad and to find out frequency of TB and drug resistance pattern by Gene Xpert. A total of 220 samples from suspected patients of TB were included in this study and 214 samples were detected as positive by Gene Xpert. Samples were classified on the basis of gender, age group (<30, 30-50 and >50 years), type of sample (sputum and pleural) and number of M. tuberculosis by ct value (cycle threshold). The results of present study showed high positive frequency of TB in male patients and in 30-50 years of age groups by Gene Xpert. High number of M. tuberculosis was found in low and medium category in TB patients. Out of 214 positive TB patients, rifampicin resistance was detected in 16 patients. In conclusion, our study identified that Gene Xpert is an effective approach for diagnosing TB by detection of M. tuberculosis and rifampicin resistance in <2 hours for rapid diagnosis and management of TB.
