ABSTRACT
BACKGROUND - Multi-drug resistant tuberculosis (MDR-TB) is an increasing health problem in India. Globally,3.5% of new TB cases and 18% of previously treated cases had MDR/RR-TB.(GLOBAL TUBERCULOSIS REPORT 2018). As per the India TB Report 2018 the estimated incidence of MDRTB/RR in India was approximately 1,47,000.Outcome of MDR patient put on MDR regime is poor due to high cost, long duration of treatment, and various side effect of second line ATT. MATERIAL & METHOD - Study comprised patients who were diagnosed MDR by culture and DST method from RNTCP accredited lab and initiated CAT–IV treatment in D.R.TB Centre, Department of Tuberculosis & Chest Diseases, S. N. Medical College, Agra. Detailed history and pre clinical evaluation as per guideline were done and at the end of 3rd ,4th,5th and 6th month sputum were send for AFB staining and culture. RESULT – Out of 109 MDR patient put on CAT-IV, culture conversion at 3rd month occur in 52(47.70%) patients, at 4th month in 58 patients (53.21%), and in 5th month 66 patients (60.55%). Out of 109 MDR TB patients 12 patients (11.01%) were found suspected XDR. CONCLUSION – MDR TB is major health problem worldwide. Due to less efficacy and more side effect of second line ATT, longer duration of treatment, MDR TB is difficult to treat even with free supply of ATT through DOTS PLUS. Close attention is needed for early diagnosis of MDR TB , and adequate clinically monitoring of during treatment is essential.
ABSTRACT
Tuberculosis is a major public health problem worldwide and remains one of the most significant causes of death from an infectious agent. India contributes to 25.5% of the global new TB case detection. In recent times, emphasis has shifted from older phenotypically and biochemical methods of diagnosis to molecular methods such as GeneXpert MTB/RIF, a real time PCR that can detect MTB and rifampicin resistence simultaneously. Methods: This study aims at assessing the performance of acid fast bacilli (AFB) smear microscopy in comparison with GeneXpert MTB RIF, in the diagnosis of pulmonary tuberculosis. Study was a cross-sectional study carried out at the Department of Pulmonary Medicine, Muzaffarnagar Medical College, from January 2018 to April 2019. Result: The detection of MTB and rifampicin resistance using the Xpert MTB/RIF assay was assessed in 67 specimens from patients suspected of having pulmonary tuberculosis and compared with conventional smear microscopy. Out of these 67 sputum specimens, 38 samples were MTB positive by smear microscopy while 56 samples were MTB detected by Gene Xpert assay. Gene Xpert detected 18 additional tubercular cases and identify two cases of Rifampicin resistant MTB. Conclusion: Study show that there was no statistically significance in diagnostic value between GeneXpert and AFB smear microscopy in sputum samples however Gene Xpert MTB/RIF is useful method for rapid detection of MTB and Rifampicin resistance simultaneously.
ABSTRACT
Background: Multidrug-resistant tuberculosis (MDR-TB) prevalence is increasing throughout the world. Although, most important risk factor for development of MDR-TB is inadequate and irregular previous treatment for tuberculosis, but newly treated patients are also at risk due to either spontaneous mutations or transmission of drug-resistant strains. The conventional tuberculosis drug susceptibility tests are sensitive and specific but they are not rapid. Newer molecular methods help in rapid diagnosis. GeneXpert MTB/RIF is a rapid method to detect MTB and rifampicin resistance. Rifampicin resistance is an initial indicator of multidrug resistance. We have tried to ascertain the prevalence of Rifampicin resistance in newly diagnosed and previously treated pulmonary tuberculosis patients. Methods: This study was a prospective cross sectional study that involved all newly diagnosed and previously treated pulmonary tuberculosis patients attending the Department of Pulmonary Medicine, Muzaffarnagar Medical College, Muzaffarnagar from January 2018 to Dec 2018. In the District Hospital, Muzaffarnagar,the sputum specimens were sent for GeneXpert MTB/RIF .On the basis of the result, the patients were labelled as Rifampicin resistance. Results: A total no of 118 sputum samples were sent to District Hospital,Muzaffarnagar for GeneXpert MTB/RIF . Among these 118 patients, 102 patients were newly diagnosed pulmonary tuberculosis and 16 patients were previously treated pulmonary tuberculosis . Prevalence of Rifampicin resistance TB was found to be 0.98 % among newly diagnosed pulmonary tuberculosis, and 25 % among previously treated pulmonary tuberculosis patients. Conclusion: In conclusion, our results showed that the prevalence of Rifampicin resistance TB was high in previously treated pulmonary tuberculosis patient in comparison to newly diagnosed pulmonary tuberculosis patient. Proper administration of first line drugs for susceptible cases is most efficient method in preventing drug resistance.
