Investigation of variations of pyrazinamide resistance and gene Xpert-based molecular typing in tuberculosis patients

The morbidity, death, and medication resistance caused by Mycobacterium tuberculosis are global health concern. The Gene Xpert is employed to diagnose TB early and find pyrazinamide (PYR) resistance at the same time. Our goal was to examine the clinical TB situation at Faisalabad's tertiary care institutions and to use Gene Xpert to determine the prevalence of TB and the drug resistance pattern. In this research, 135 samples from probable TB patients were included, and Gene Xpert identified 127 samples as positive. The gender, age group (50 years), sample type (sputum and pleural), and number of M. tuberculosis by ct value (cycle threshold) were all taken into consideration when categorizing the samples. The findings of the current investigation revealed a significant positive frequency of TB in male patients and in the 31-50 years age ranges. Patients with TB had a high prevalence of M. tuberculosis in the low and medium categories. 16 of the 127 TB patients who tested positive for the disease had pyrazinamide resistance. Our study concluded that Gene Xpert is a useful method for quickly diagnosing and treating TB since it can quickly detect M. tuberculosis and pyrazinamide resistance.
