Study the prevalence of rifampicin resistance among pulmonary tuberculosis patients by genexpert assay from a tertiary care hospital of North India
Background: Rifampicin (RIF) resistance (RR) tuberculosis (TB) has posed a great challenge to TB control programs globally. Evidence of RIF-RR can help as a surrogate marker to find out multidrug-resistance cases. The study aimed to determine the prevalence of RIF-RR in pulmonary TB (PTB) patients...

description | Background: Rifampicin (RIF) resistance (RR) tuberculosis (TB) has posed a great challenge to TB control programs globally. Evidence of RIF-RR can help as a surrogate marker to find out multidrug-resistance cases. The study aimed to determine the prevalence of RIF-RR in pulmonary TB (PTB) patients over the 4 years at Dr. RPGMC, Tanda, from the year 2018 to 2021. Methods: This was a retrospective study conducted at Dr. RPGMC, Tanda at Kangra, where we checked (from January 2018 to December 2021) clinically suspected PTB patients, whose samples were sent to the laboratory for GeneXpert assay to identify Mycobacterium TB/RIF (MTB/RIF) testing. Results: Of the total 11,774 clinically suspected PTB specimens were collected, and identified by GeneXpert MTB/RIF assay, in which 2358 samples were MTB positive and 9416 were MTB negative. Among 2358 MTB-positive samples, 2240 (95%) samples were RIF sensitive, in which 1553 (65.9%) were males and 687 (29.1%) were females, 76 (3.2%) samples were RIF-RR, in which 51 (2.2%) were males and 25 (1%) were females, and 42 (1.8%) samples were RIF indeterminate, in which 25 (1%) were males and 17 (0.8%) were females. Conclusion: The rate of RIF-RR was found 3.2% of total samples which was more in males. The overall positivity rate was 20%, and the rate of positivity decreased from 32% to 14% over the 4 years in sputum samples. Hence, the GeneXpert assay was found to be very important tool to detect RIF-RR among suspected PTB patients. |
