Anti-tuberculosis drugs have been used for many decades but resistance to them is now widespread. Globally 5% of tuberculosis cases and in India 3% among new TB cases. This study was planned to know the pattern of first line anti-tuberculosis drug resistance in south Gujarat, Surat region in newly diagnosed patients of tuberculosis. Material and Methods: 350 samples were processed for homogenisation and concentration using 4% NAOH-2.9% trisodium citrate. Processed samples were inoculated in liquid medium that is MGIT (Mycobacterial growth indicator tube). Positive samples for M. tbwere processed further for first line anti-tuberculosis drugs sensitivity testing (DST). Reading was taken by using MicroMGIT system. Result: Out of 350 samples 59 (17%) were positive samples, of which 48 (13%) were M. tb and 11 (3%) were non tuberculous mycobacteria. Out of 48 samples 2% (1 isolate) was resistant to isoniazid and Rifampicin while 2% were monoresistant to isoniazide, 2% monoresistant to streptomycin. No rifampicin monoresistant was detected. Conclusion: Such study may help in control of tuberculosis at regional and national level which would in turn help in planning of measures to control Multi-drug resistance tuberculosis. Continuous surveillance should be applied to know the periodic changing patterns and trend in Drug resistant tuberculosis.展开更多

Cases of MDR-TB are now increasing with 30,000 cases of MDR-TB reported in 2013 by national TB programme. Rapid diagnosis of MDR-TB is extremely important for rapid treatment of patient and to prevent spread of MDR-TB to other. BACTEC 960 system helps in rapid diagnosis but purchase of expensive instrument for the same is the limitation. However, the same purpose can be solved by use of semi-automated MGIT system. Aims and Objectives: Aim of this study is to do drug sensitivity testing of the first line anti-tuberculosis drugs with the use of semi-automated MGIT systems. 350 newly registered and suspected cases of tuberculosis in tertiary care hospital were included. Samples were processed for digestion and decontamination and inoculated in MGIT tubes and also on LJ medium. Reading was taken using semi-automated MGIT system. Positive tubes were confirmed by rapid test for M. tuberculosis and then drug sensitivity was performed. Result: Out of 350 samples, 62% were sputum;33% were pleural fluid and rest 5% were lymph node, Ascetic fluid, CSF, pus. Average day of positivity by MGIT was 13 - 20 days as compared to 25 - 37 days by solid medium, which was statistically significant with p value Conclusion: Manual MGIT System is a simple, efficient, safe to use diagnostic system. It does not require any expensive/special instrumentation other than the UV lamp for detection of fluorescence. The rapidity by which mycobacteria are detected is the most important advantage of the Manual MGIT. In areas with limited resources where purchase of expensive instruments such as the MGIT960 is out of scope, the use of manual MGIT for rapid susceptibility testing for MDR-TB could be a possibility.展开更多

Drug resistance is difficult to treat due to its associated cost and side effects. The objective of this study was to assess the drug resistance pattern and assess risk factor associated with MDR-TB among pulmonary tuberculosis patients attending National Tuberculosis Center. Methodology: The comparative cross sectional study was conducted at National Tuberculosis Center during August 2015 to February 2015. Early morning sputum samples were collected from pulmonary tuberculosis suspected patients and subjected to Ziehl-Neelsen staining and fluorochrome staining and culture on Lowenstein-Jensen (LJ) medium. Drug Susceptibility test was performed on culture positive isolates by using proportion method. Univariate and multivariate analysis was computed to assess the risk factors of MDR-TB. Results: Out of 223 sputum samples, 105 were fluorochrome staining positive, 85 were ZN staining positive and 102 were culture positive. Out of 102 culture positive isolates, 37.2% were resistance to any four anti-TB drugs. 11 (28.9%) were initial drug resistance and 28 (43.7%) were acquired drug resistance. The overall prevalence of MDR-TB was 11.7%, of which 2 (5.3%) were initial MDR-TB and 10 (15.6%) were acquired MDR-TB. Univariate and multivariate analysis showed female were significantly associated (P = 0.05) with MDR-TB. Conclusion: Drug resistance TB particularly MDR-TB is high. The most common resistance pattern observed in this study was resistance to both isoniazid and rifampicin. Female were found to be associated with MDR-TB. Thus, early diagnosis of TB and provision of culture and DST are crucial in order to combat the threat of DR-TB.展开更多

The level of peroxynitrite (ONOO^(-)) generated in liver has long been regarded as a biomarker for the prediction and measurement of drug-induced liver injury (DILI). In this article, we constructed a BODIPY-based fluorescent probe (BDP-Py^(+)) that enabled quickly and sensitively detect and image ONOO^(-) in vivo. Utilizing this probe, we demonstrated the change of ONOO^(-) content in cells and mice model of DILI induced by acetaminophen (APAP), and for the first time revealed the mechanism of liver injury induced by antituberculosis drug PZA. Moreover, BDP-Py^(+) could be applied to screen out and evaluate the hepatotoxicity of different anti-tuberculosis drugs. Comparing with the existing serum enzymes detection and H&E staining, the probe could achieve early diagnosis of DILI before solid lesions in liver via monitoring the up-regulation of ONOO^(-) levels. Collectively, this work will promote the understanding of the pathogenesis of anti-tuberculosis drug induced liver injury (ATB-DILI), and provide a powerful tool for the early diagnosis and treatment of DILI.展开更多

Aims of the study: This study examined risk factors associated with poor response to initial treatment with four anti-TB drug regimens or three drug regimens with steroids as adjuvant therapy. Methods: This study analyzed medical records from two tertiary hospitals in Busan, Korea, between January 2009 and March 2012. The subjects were non-human immunodeficiency virus (HIV)-infected patients aged ≥16 years with clinical CNS TB. The subjects were divided into two groups according to response to treatment. Results: In totally, 52 patients with CNS TB were included. Of these, 14 (26%) and 38 (73%) showed poor and good responses, respectively. Of the patients with poor response, nine had stage III disease (64.3%) according to the British Medical Research Council (BMRC) staging system. A significantly higher proportion was seen in the good response group (p < 0.05). Patients with positive cerebrospinal fluid (CSF) acid-fast bacillus (AFB) culture, positive sputum AFB culture, positive CSF TB polymerase chain reaction (PCR) results, and brain tuberculoma had poorer responses (p < 0.05). Multivariate analysis to determine risk factors associated with poor response to anti-TB therapy revealed that a poor response was associated with stage III clinical signs upon diagnosis (odds ratio [OR] 32.122;95% confidence interval [CI] 2.221 - 464.605), positive sputum AFB culture (OR 13.624;95% CI 1.066 - 174.149), and tuberculoma on brain images (OR 45.714;95% CI 1.893 - 1104.018). Conclusions: The results demonstrate the importance of identifying the severity of CNS TB and promptly administering anti-TB drugs. It is necessary to perform drug susceptibility testing for anti-TB drugs. Further studies are needed to confirm the correlations between risk factors associated with poor response and anti-TB drug resistance and the other risk factors.展开更多
