Introduction: Ethiopia stood third in drug-resistant tuberculosis (TB) in Africa, and more than 5,000 MDR-TB patients are reported each year. Greater than 90% of rifampicin (RIF) resistant strains are resistant to isoniazid (INH) and hence the objective of this study was to determine the prevalence and risk factors of RIF resistant MTB among presumptive TB cases at Dubti General Hospital, Afar, Ethiopia. Methodology: In this cross-sectional study, 384 presumptive TB cases were recruited and a structured questionnaire was used to collect socio-demographic and clinical data. Sputum samples were collected and examined using X-pertMTB/RIF assay. Bivariate, multivariate logistic regressions, and fishers' exact analysis were done to assess the associations between the prevalence of TB and MDR-TB with different socio-demographic and clinical variables. Results: In the present study, the overall prevalence of pulmonary TB was 24.5% (94/384), of this 4 (4.3%) isolates were resistant to RIF. History of anti-TB treatment (AOR = 2.4, 95% CI: 1.3-4.4 and TB contact (AOR = 3.6, 95% CI: 2.1-6.2 were significantly associated with gene X-pert MTB/RIF positive TB. Moreover, resistance to rifampicin was statistically associated with the history of TB contact with multi-drug resistant TB (P = 0.027) and khat chewer cases (P = 0.04). Conclusions: The overall prevalence of TB and its drug-resistant were relatively higher than that of in the general population in Ethiopia. History of anti-TB treatment and TB contact were significantly associated with X-pert MTB/RIF positive MDR-TB.

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: In Uganda, 12% of previously treated TB cases and 1.6% of new cases have MDR-TB and require specialized treatment and care. Adherence is crucial for improving MDR-TB treatment outcomes. There is paucity of information on the extent to which these patients adhere to treatment and what the drivers of non-adherence are. Methods: We conducted a cohort study using retrospectively collected routine program data for patients treated for MDR- TB between January 2012 – May 2016 at Mulago Hospital. We extracted anonymized data on non-adherence (missing 10% or more of DOT), socio-economic, demographic, and treatment characteristics of the patients. All participants were sen- sitive to MDR-TB drugs after second line Drug Susceptible Testing (DST) at entry into the study. Factors associated with non-adherence to MDR-TB treatment were determined using generalized linear models for the binomial family with log link and robust standard errors. We considered a p- value less than 0.05 as statistically significant. Results: The records of 227 MDR- TB patients met the inclusion criteria, 39.4% of whom were female, 32.6% aged be- tween 25 – 34 years, and 54.6% living with HIV/AIDS. About 11.9% of the patients were non-adherent. The main driver for non-adherence was history of previous DR-TB treatment; previously treated DR-TB patients were 3.46 (Adjusted prev- alence ratio: 3.46, 95 % CI: 1.68 - 7.14) times more likely to be non-adherent. Conclusion: One in 10 MDR-TB patients treated at Mulago hospital is non-adherent to treatment. History of previous DR- TB treatment was significantly associated with non-adherence in this study. MDR-TB program should strengthen adherence counselling, strengthen DST surveillance, and close monitoring for previously treated DR-TB patients. Keywords: Non-adherence; multi-drug resistant tuberculosis; treatment.

Data on availability and cost of anti-tuberculosis (TB) drugs in relation to affordability at national level are scarce.We performed a cross-sectional study on availability and cost of anti-TB drugs at major TB-reference centres in 37 European countries. Costs of standardised treatment regimens used for pan-sensitive TB, multidrug-resistant (MDR) TB, pre-extensively drug-resistant (XDR) TB, and XDR-TB were compared using a purchasing power analysis. Affordability was evaluated in relation to monthly national gross domestic products per capita (GDP).At least one second-line injectable and either moxifloxacin or levofloxacin were available in all countries. Linezolid and clofazimine were available in 79% and 46% of the countries, respectively. Drug cost for XDR-TB was three-times more expensive than those for MDR-TB. The average price of treatment for pan-sensitive TB represented a maximum of 8.5% of the monthly GDP across countries, while for standard MDR-TB treatment this was <30% in only six countries and more than 100% in four countries. Treatment of XDR-TB represented more than 100% of a month's GDP in all countries where the regimen was available.High cost and limited availability of drugs for treatment of drug-resistant TB, particularly beyond resistance to first-line drugs, are a major impediment to successful TB control in Europe.

Background: Tuberculosis (TB) is the leading cause of morbidity and mortality among chronic infectious diseases. Objective: The goal of this cross-sectional study (2011-2013;2013) was to examine the patterns of TB drug resistance among HIV-negative pulmonary TB patients in regions near the Iranian border. Method: To this end, MTB isolates were harvested from 300 HIV-negative, pulmonary smear-positive TB patients from the northwest and west Iranian border provinces. Isolates were subjected to first and second-line drug susceptibility testing by the 1% proportion method. Demographic and clinical data were provided using a questionnaire and information from patient records. Results were analyzed using SPSS-18. Results: The mean age of the patients was 52.03 years and 54.3% were male. The prevalence of resistance to any TB drug was 13.6% (38 cases). Eleven percent of the new treatment TB group (28 patients) and 40.7% of the retreatment TB group (11 patients) were resistant to all TB drugs. Twelve (4.3%) patients had multidrug-resistant tuberculosis (MDR-TB) (2.38% in the new TB treatment group and 23.1% in the retreatment group). One patient had extensively drug-resistant tuberculosis (XDR-TB). There was a statistically significant relationship between TB drug resistance and smoking (p=0.02) and a history of migration from village to city (p=0.04), also between TB drug resistance and recurrence of TB in patients that had previously received treatment (p<0.001). Conclusion: Knowledge of drug resistance patterns for new and previously treated cases is critical for effective control of MDR-TB in different regions of the country. The burden of MDR-TB in retreatment cases was high. Previous TB treatment was one of the most important mokers and those who had a history of rural to urban migration were at high risk for the occurrence of TB drug resistance.

Introduction: The incidence of drug-resistant tuberculosis (TB) is rapidly increasing worldwide. Children in high TB burden countries are rapidly being reported to be affected by multidrug-resistant TB (resistant to isoniazid and rifampicin). The aim of this study is to evaluate the pattern of drug sensitivity among children suffering with TB. Methods: Known cases of pulmonary TB, with sputum smear positive even after two months of compliance to 1st line anti-tuberculous therapy were included after gaining informed consent. Specimens used for drug sensitivity analysis were either sputum or bronchoalveolar lavage. Patient age, gender, history of TB contact, and duration of treatment were also recorded. Data was entered and analyzed using SPSS v.22. Results: There were 32 male (64%) and 18 female (36%) children in the study. Their mean age was 12.84 ± 2.54 years. History of household TB contact was positive in 29 (58%) children. Among 1st line anti-tuberculous therapy, ethambutol and streptomycin were most sensitive (n=44; 88%). Rifampin was least sensitive (n=17; 34%). There were 32 (64%) children with multidrug-resistant tuberculosis (MDR-TB). A positive history of household TB contact (either resistant or non-resistant) was seen to have a statistically significant impact on incidence of MDR-TB (p value=0.03) Conclusion: Pediatric drug-resistant TB is a rising concern. Awareness programs on national and international levels are needed to educate the general population regarding the importance of preventing TB household contact, especially amongst children.

Background: India has the highest burden of tuberculosis globally while second highest in estimated MDR-TB cases after China. The prevalence of MDR-TB is estimated to be 3% among new cases and 14-17% amongst the re-treatment cases. The Objective of the study was to identify the risk factors of MDR-TB in patients registered at tuberculosis units of urban Allahabad.Methods: A cross-sectional study was carried out on TB patients registered at the urban tuberculosis units of Allahabad district in the year 2015. A total of 54 MDR-TB and 1016 non-MDR TB patients were included in the study. A pre-tested structured questionnaire was used to collect the data on the various factors. The chi-square test was used to study the association of various risk factors for MDR-TB patients.Results: MDR-TB was more common in 26-45 year age group (59.26%), males (62.96%), previously treated TB case (83.34%), positive history of contact with MDR-TB patient (5.55%), patients previously on non-DOTS treatment (37.78%), patients with associated co-morbidities (37.03%) and in substance abuse (74.07%) while Non-MDR is more common in >45 years (46.75%) age group, females (56.69%), new cases (87.20%), patients on DOTS therapy (85.16%), without any co-morbidities (83.46%) and in patients having positive history of substance abuse (60.04%).Conclusions: The younger age, male gender previous TB treatment, patients previously on Non-DOTS treatment, incomplete previous TB treatment, positive contact history of MDR-TB cases, presence of associated co-morbidities and substance abuse was significantly associated with MDR-TB patients than Non-MDR-TB patients (p<0.05).

BACKGROUND: Multi-drug Resistant Tuberculosis (MDR-TB) is found to be a major public health problem both in developed and developing countries. Ethiopia is one of the 30 high MDR-TB burden countries in the world. Although several studies were done to identify the determinants of MDR-TB, the reported findings are heterogeneous across the world.METHODS: Unmatched case-control study was conducted at Debre Markose Referral Hospital, Debre Birhan Referral Hospital, and Boru Media District Hospital in Amhara Region, Northern Ethiopia, from March 01/2019- April 30/2019. Cases were all tuberculosis patients with culture or line probe assay confirmed mycobacterium tuberculosis resistant to at least both Isoniazid and Rifampicin and registered on second-line TB treatment. Controls were all patients with Bacteriological (molecular) proven drug-susceptible TB strains and whose recent smears result were turned to negative and registered as cured from January 01/2014 – December 31/2018. A pre-tested checklist was used to collect the data.RESULT: Of the total reviewed documents (393), 98 cases and 295 controls were involved in this study. And, 54(55.1%) among cases and 162(54.9%) among controls were males. sixty nine(70.4%) among cases and 163(55.3) among controls were within the age group of 26-45 years. In the multivariable logistic regression analysis, age between 26-45years old (AOR=3.35; 95% CI: 1.15, 9.77), previous history of TB treatment (AOR= 14.2;95%CI: 7.8, 25.3) and being HIV positive (AOR=4.4; 95% CI:1.8, 10.4) were significantly associated with MDR-TB.CONCLUSION: Age between 26-45 years old, previously treated cases and TB/HIV co-infection were identified as the determinants of MDR-TB. Special attention should be given to age between 26-45 years old, previous history of TB treatment and TB/HIV co-infection to prevent and control MDR-TB in the local context.

The emergence of drug-resistant tuberculosis (DR-TB) is becoming a challenge to the national TB control programs including Ethiopia. Different risk factors are associated with the emergence of DR-TB. Identifying these risk factors in a local setting is important to strengthen the effort to prevent and control DR-TB. Thus, this study aimed to assess the risk factors associated with drug-resistant TB in Ethiopia. The Preferred Reporting Items for Systematic Reviews and Meta-analysis checklist was followed to conduct this study. We systematically searched the articles from electronic databases and gray literature sources. We used the Joanna Briggs Institute Critical Appraisal tools to assess the quality of studies. Data were analyzed using STATA version 15. We estimated the pooled OR along with 95%CI for each risk factor. The heterogeneity of the studies was assessed using the forest plot and I heterogeneity test. Besides, we explored the presence of publication bias through visual inspection of the funnel plot and Egger’s regression test. After intense searching, we found 2238 articles, and 27 eligible studies were included in the final analysis. Based on the pooled analysis of the odds ratio, unemployment (OR; 2.71, 95% CI; 1.64, 3.78), having a history of the previous TB (OR; 4.83, 95% CI; 3.02, 6.64), having contact with a known TB patient (OR; 1.72, 95% CI; 1.05, 2.40), having contact with a known MDR-TB patient (OR; 2.54, 95% CI; 1.46, 3.63), and having pulmonary TB (OR; 1.80, 95% CI; 1.14, 2.45) were found to be the risk factors of drug-resistant TB. While older age TB patients (OR; 0.77, 95% CI; 0.60, 0.95) including age above 45 years OR; (0.76, 95% CI; 0.55, 0.97), and males (OR; 0.86, 95% CI; 0.76, 0.97) were found to had lower risk of DR-TB compared to their counterparts. A previous history of TB treatment is a major risk factor for acquiring DR-TB in Ethiopia that might be due to poor adherence during the first-line anti TB treatment. Besides, having contact with a known TB patient, having contact with a known MDR-TB patient, having pulmonary TB, and being unemployed were the risk factors of DR-TB in Ethiopia. Thus, active screening of TB contacts for DR-TB might help to detect DR-TB cases as early as possible and could help to mitigate its further transmission across the community.

ObjectiveThe aim of this study was to assess the knowledge and practice of health workers about multidrug-resistant tuberculosis (MDR-TB) prevention and control.Study design and settingsA cross-sectional study was conducted at Gondar University Referral Hospital and Felege Hiwot Referral Hospital.ParticipantsRandomly selected health workers (ie, medical doctor, nurse, health officer, pharmacy, medical laboratory and midwifery) were the study participants.Outcome measuresThe main outcomes were knowledge and self-reported practice of health workers about MDR-TB.ResultsA total of 377 health workers (with a response rate of 93.7%) participated in the study. The majority of respondents were nurses (52.5%, n=198) and medical doctors (15.6%, n=59). The mean knowledge score was seven out of 10; 149 (39.5%) of respondents scored seven or more which was considered as good knowledge. MDR-TB knowledge of health workers was significantly associated with having a postgraduate degree (adjusted odds ratio (AOR)=5.78; 95% CI 2.33 to 14.33), taking infection prevention training (AOR=1.79; 95% CI 1.00, to 3.17) and having a history of tuberculosis (TB) (AOR=1.85; 95% CI 1.12, to 3.03). The mean self-reported practice score was four out of seven; one-fifth (19.6%) of respondents scored four or more which was considered as good practice. Self-reported practice of health workers was significantly associated with working at internal medicine (AOR=4.64; 95% CI 1.99, to 10.81) and paediatrics (AOR=3.85; 95% CI 1.11, to 13.34) wards, being in the age groups of 26–30 years (AOR=2.70; 95% CI 1.27, to 5.76), and 30 years and above (AOR=4.42; 95% CI 1.77, to 11.00).ConclusionsThis study found low knowledge and self-reported practice score among health workers. MDR-TB knowledge of health workers was significantly associated with educational status, infection prevention training and previous history of TB. This finding highlights the potential of providing MDR-TB training for health workers to increase their knowledge about MDR-TB.
