Abstract Background Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. The emergence of Mono or multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis (XDR-TB), poses a considerable challenge to Mycobacterium tuberculosis control programs in the worldwide; however, there has been no reliable and organized data on trends and prevalence drug resistance of Mycobacterium tuberculosis in study area; Therefore, aim of this study to determine the trends of Mycobacterium tuberculosis and prevalence of Rifampicin resistance in eastern zone, Tigray, Northern Ethiopia. Methods Hospital based retrospective cross-sectional study was conducted at Adigrat General Hospital from June 01 to August 30, 2019.Data was collected retrospectively from the registration books using data extraction format commence January 01, 2015, December 30, 2018. Data was entered into Epi-Info 3.1 and exported and analyzed using SPSS Version 20. The results were summarized using descriptive statistics, tables, and figures. P values < 0.05 would be considered statistically significant. Result A total of 5,944 Mycobacterium tuberculosis presumptive patients were included in the study. The majority of the study participants were male (58.1%). The median age of the participants was 40.0 (IQR 57, 26) years, the majority age-group was 30-44 years. The overall prevalence of Mycobacterium tuberculosis was 1446 (24.3%). Of the total confirmed cases, 132 (9.1%) were resistant to rifampicin. From total Rifampicin resistant 129 (97.7%) new cases and the rest were previously treated tuberculosis patients. Age, reason for diagnosis, site of presumptive tuberculosis, being HIV infected was found a significant association with our dependent variable; however, only Age and being HIV infected associated with rifampicin resistance. Conclusion In our study, the overall trends of Mycobacterium tuberculosis and prevalence of rifampicin resistance were found high and increased; therefore, maximizing early detection of drug-resistant Mycobacterium tuberculosis and strengthening TB infection control activities and proper implementation of directly observed treatment are recommended reducing the burden of this contagious disease.

P values < 0.05 were considered statistically significant.Result: A total of 5,944 Mycobacterium tuberculosis presumptive patients were included in the study. The majority of the study participants were male (58.1%) with participants’ median age of 40.0 (IQR 57, 26) years, the majority were 30-44 years. The overall positive cases of Mycobacterium tuberculosis was 24.3% (1446) with a total of 132 (9.1%) found to be resistant to rifampicin. Within the total Rifampicin resistant sub-group, 129/132 (97.7 %) were newly identified cases and the rest were previously treated, tuberculosis patients. Age, the reason for diagnosis, site of presumptive tuberculosis, and/or being HIV infected showed significant association with our dependent variable; however, only age and being HIV infected were associated with rifampicin resistance.Conclusion: In our study, the overall trends of Mycobacterium tuberculosis and rifampicin resistance were found to be high and gradually increasing. HIV co-infected and previously treated patients were more likely to develop rifampicin resistance. Therefore, maximizing early detection of drug-resistant Mycobacterium tuberculosis and strengthening tuberculosis infection control activities are recommended to reduce the burden of this contagious and potentially deadly disease.

Abstract Background: Tuberculosis (TB) is the second leading cause of mortality from an infectious disease worldwide. Multidrug-resistant tuberculosis (MDR-TB), where rifampicin-resistant TB is the most contributor, remains a global health threat. There is scant data on MTB and rifampicin resistance (RR-MTB) using Gene Xpert MTB/RIF assay in Ethiopia, particularly in the study area. This study aimed at determining the prevalence of MTB and RR-MTB among presumptive TB patients in Tigray, Northern Ethiopia.Methods: A multi-center retrospective cross-sectional study was conducted from October 2019 to December 2019 among presumptive MTB patients from four governmental hospitals in Tigray regional state. Records of sputum sample results of presumptive MTB patients with Gene Xpert MTB/RIF assay from January 2016 to December 2019 were investigated. Data-extraction tool was used to collect data from registration books and analyzed using SPSS ver.21 statistical software. Statistically significant was set at P-value ≤ 0.05. Results: Out of the total 17,329 presumptive adult MTB patients who had submitted sputum samples for TB diagnosis, 16,437 (94.9%) had complete data and were included in the study. More than half (60.2%) of them were males and the age of the patients ranged from 18-98 years, with a mean age of 44.2 (±16.4 SD) years. The majority, 15,047(91.5%) and 11,750 (71.5%) of the participants were new cases and with unknown HIV status, respectively. Prevalence of MTB was 9.7% (95% CI: 9.2-10.2%) of these, rifampicin resistant-MTB was 8.7% (95% CI: 7.32-10.09%). Age (being greater than 29 years) [p < 0.001] and new cases [AOR= 0.46; 95%CI = 0.39, 0.53, p < 0.001] were associated with low TB infection. Whereas age groups of 18-29 years were associated with higher RR-MTB [AOR= 3.08; 95% CI= 1.07, 8.72, p = 0.036]. Gender (being male) [AOR= 0.68; 95 % CI= 0.47, 0.96, p= 0.032] and having no history of previous treatment [AOR= 0.29; 95 % CI= 0.202, 0.44, p < 0.001] were associated with lower RR-MTB. Conclusion: Nearly one-tenth of the presumptive tuberculosis patients tested positive for MTB; out of those, 8.7% were positive rifampicin-resistant-MTB. The high prevalence of TB and RR-MTB at a young age and previously treated cases calls for a concerted effort to improve and monitor TB treatment to reduce the problem.

Introduction: Multidrug resistant tuberculosis (MDR-TB) is defined as a case of tuberculosis resistant to rifampicin and isoniazid which are the first line anti tuberculosis drugs. Globally emergences of MDR-TB possess a challenge to TB control. In Bhutan, the proportion of MDR-TB is high at par with the global level. This study will explore the predictors of MDR-TB and the trend at Samtse General Hospital which has high burden of tuberculosis. Methods: This was a retrospective cross sectional study. The data was extracted from TB treatment cards maintained at TB unit of Samtse General Hospital TB from January 2012 to June 2018. Results: The study showed the prevalence of drug resistant to at least one drug at 21% and MDR-TB prevalence at 16%. The patients with previous treatments (AOR: 4.59; 95% CI .03-.18) and patients under the age of 30 years (AOR: 2.7; 95% CI 1.01- 7.42) were significantly associated with MDR-TB. Conclusion: This study shows high prevalence of MDR-TB in Samtse. Better strategies and concrete actions need to be developed to combat the increase of MDR-TB.

Background: Drug resistant tuberculosis threatens global TB control and is a major public health problem in several countries and India has the highest tuberculosis in the world. The rifampicin resistance is a good predictor of multidrug resistant tuberculosis. The aim of this study was to determine the prevalence of rifampicin resistance M. tuberculosis and associated factor among presumptive tuberculosis patients in eastern Uttar Pradesh.Methods: A cross-sectional study was conducted from October 2016 to September 2017. Detection of M. tuberculosis and resistance to rifampicin was performed using Gene Xpert MTB/RIF assay. Data was collected using pre-structured questionnaire by face to face interview. The chi-square test was used to assess the statistical significance of each ratio, p<0.05 was considered significant.Results: Out of 510 patients, Mycobacterium tuberculosis was detected in 168 (32.9%). Out of these 168 patients, the prevalence of rifampicin resistance tuberculosis was 44 (26.1%). It was higher among male 38 (30.6%) than female 6 (13.6%). Regarding age distribution, maximum numbers of rifampicin resistance patients were in the age group of 20-40 years 36.7%. The prevalence of rifampicin resistance was 36 (27.6%) and 8 (21.0%) in pulmonary and extra-pulmonary respectively. Out of 44 rifampicin resistant cases, 39 (37.8%) were previously treated and 5 (7.6%) cases were treatment naïve patients. In this study, among presumptive DRTB cases, new 2 (11.7%), relapse 13 (39.3%), failure 23 (46.0%), loss to follow-up 1 (10.0%) and MDR contact 1 (20.0%) respectively were rifampicin resistant and one HIV seropositive patient was found to be rifampicin resistant.Conclusions: Previously treated cases were significantly associated with rifampicin resistance tuberculosis. The Gene Xpert is a good equipment for rapid detection and management of drug resistant tuberculosis for both pulmonary as well as extra-pulmonary tuberculosis.

Objective: Drug resistant tuberculosis has long been a common problem prevailing in developing countries including Bangladesh. Present study focused on the rapid identification of live Mycobacterium tuberculosis among treatment failure cases.Materials and Methods: Sputum samples from a total of 100 category-I and category-II treatment failure cases, assumed as multidrug resistant tuberculosis, were studied through fluorescein diacetate (FDA) staining under light emitting diode (LED) fluorescence microscope. Considering culture method as gold standard, we also compared the results of FDA staining with that of auramine O staining.Results: A total of 85% acid-fast bacilli were detected by FDA staining, 82% by auramine O staining and a total of 85% isolates were detected in Lowenstein-Jensen (LJ) culture. The sensitivity of FDA staining (96.47%) was estimated to be slightly higher than that of auramine O staining (91.76%). Moreover,76.47% cases were detected as multidrug resistant tuberculosis (MDR-TB). Conclusion: Taken together, FDA staining method has been proposed to be appropriate for the rapid diagnosis of drug resistant tuberculosis.
