CBNAAT: Advantage and Efficacy in Pulmonary Tuberculosis (PTB) atop on Traditional Methods for Diagnosis in a Tertiary Care Hospital in India

Background: Mycobacterium Tuberculosis (MTB) is one of the most ancient diseases of mankind. Pulmonary tuberculosis (PTB) is the most common, despite the diagnosis and treatment of TB. Many studies reported, a collaboration between PTB susceptibility. In our research study, we report meantime findings after enrolling 732 of a planned 212 participants.

Study Design: A descriptive cross-sectional study.

Methods: The study conducted on patients with TB in west India was conducted in the Department of Microbiology, Index Medical College; Indore Madhya Pradesh. Patients suspected of PTB were qualified for screening if their age varied from 25 to 60 years and with both gender, signs and symptoms associated with PTB such as cough for more than 2 weeks, fever, weight loss, chest pain, and abnormal chest X-ray findings in results and cartridge-based nucleic acid amplification test (CBNAAT) positive. All Patients were monitored monthly while they visited in TB and chest clinic for TB treatment.

Results: A total of 937 patients were selected for the study. Out of which only 732 patients were enrolled. About 212 patents were positive for CBNAAT and 520 were found negative. The confirmed positive CBNAAT patients do not have a history of tuberculosis. In this study about 21.72% were ZN stain positive, 33.46% were culture positive and 28.96% were CBNAAT positive.

Conclusion: The current scenario of traditionally AFB-negative PTB is not sensitive enough to establish the diagnosis of active tuberculosis without CBNAAT. They underdiagnose PTB and over-treat people without PTB.
