Abstract
Background The existence of Type 2 Diabetes Mellitus (DM) in tuberculosis (TB) patients is very dangerous for the health of patients. One of the major concerns is the emergence of MDR-TB in such patients. It is suspected that the development of MDR-TB further worsens the treatment outcomes of TB such as treatment failure and thus, causes disease progression. Aim To investigate the impact of DM on the Emergence of MDR-TB and Treatment Failure in TB-DM comorbid patients. Methodology The PubMed database was systematically searched until April 03, 2022 (date last searched). Thirty studies met the inclusion criteria and were included in this study after a proper selection process. Results Tuberculosis-Diabetes Mellitus patients were at higher risk to develop MDR-TB as compared to TB-non-DM patients (HR 0.81, 95% CI: 0.60-0.96, p < 0.001). Heterogeneity observed among included studies was moderate (I2 = 38%). No significant change was observed in the results after sub-group analysis by study design (HR 0.81, 95% CI: 0.61-0.96, p < 0.000). In the case of treatment failure, TB-DM patients were at higher risk to experience treatment failure rates as compared to TB-non-DM patients (HR 0.46, 95% CI: 0.27-0.67, p < 0.001). Conclusion The results showed that DM had a significant impact on the emergence of MDR-TB in TB-diabetes comorbid patients as compared to TB-non-DM patients. DM enhanced the risk of TB treatment failure rates in TB-diabetes patients as compared to TB-non-DM patients. Our study highlights the need for earlier screening of MDR-TB, thorough MDR-TB monitoring, and designing proper and effective treatment strategies to prevent disease progression.

Abstract
BACKGROUND: Past tuberculosis therapy has been linked to an increased chance of developing multidrug-resistant tuberculosis (MDR-TB). Indonesia is placed 8th among the 27 nations with "high-burden" MDR-TB.
AIM: The purpose of this study was to determine the risk factors associated of multidrug-resistance tuberculosis among minangkabau ethnicity in Indonesia.
METHODS: The authors conducted a case control study. Data were gathered in Dr. M Djamil General Hospital Padang, Lubuk Alung Hospital Pariaman and Primary Health Care in Padang Pariaman District from December 2019-March 2020. In this study, there were 73 cases (MDR-TB) and 219 controls (Tuberculosis) who were matched by age and sex. The sampling technique in this research was convenience sampling. Data were gathered from medical records. Bivariate and multivariate analysis were investigated using chi-square and logistic binary regression test. The data were analyzed using STATA version 14.2.
Results: The risk factors for MDR-TB, cavitary pulmonary had the highest odds ratio (OR = 113.54 [95% CI 15.02-858.54]), followed by TB outside the lung (OR = 38,68 [95% CI 4.89-305.43]), nutritional status (OR = 10.92 [95% CI 5.79-20.56]), alcohol consumption (OR = 6.45 [95% CI 1.57-26.48]), working status (OR = 4.08 [95% CI 2.33-7.17]), level of education (OR = 2.79 [95% CI 1.61-4.85]), history of close contact to patients with MDR-TB and TB (OR = 2.35 [95% CI 1.30-4.22]) and diabetes mellitus (OR = 2.12 [95% CI 1.15-3.91]). Multivariate analysis found that patients with a cavitary pulmonary was significant dominant factors for MDR-TB.
Conclusion: MDR-TB was predicted by previous tuberculosis therapy and cavitary pulmonary disease.

Infect Drug Resist 2022; 15:4137-4147. [PMID: 35937782 PMCID: PMC9348136 DOI: 10.2147/idr.s373125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 07/13/2022] [Indexed: 12/03/2022] Open
Abstract
Purpose The emergence of drug-resistant tuberculosis (DR-TB) represents a threat to the control of tuberculosis. This study aimed to estimate the patterns and trends of DR-TB in patients with suspected DR-TB. In addition, risk factors for multidrug-resistant tuberculosis (MDR-TB) were identified among suspected DR-TB patients in Dalian, China. Patients and Methods A total of 5661 patients with suspected DR-TB from Jan 1, 2013 to Dec 31, 2020 were included in the final analysis. The resistance pattern of all resistant strains was determined by drug susceptibility testing (DST) using the conventional Lowenstein-Jensen Proportion Method (LJ). DR-TB trends were estimated from 2013 to 2020. During the research period, the chi-square test was employed to analyze the significance of linear drug-resistance trends across time. Bivariate and multivariate logistic regression were performed to assess factors associated with MDR-TB. Results From 2013 to 2020, the resistance rates of rifampicin (RFP) and isoniazid (INH) decreased significantly, whereas the resistance rates of ethambutol (EMB) and streptomycin (SM) increased in patients with suspected DR-TB. From 2013 to 2020, the prevalence of DR-TB decreased in all patients from 34.71% to 28.01% with an average annual decrease of 3.02%. Among new cases, from 2013 to 2020, the prevalence of DR-TB (from 26.67% to 24.75%), RFP-resistant TB (RR-TB) (from 15.09% to 3.00%) and MDR-TB (from 6.08% to 2.62%) showed a significant downward trend. Among patients with a previous treatment history, DR-TB (from 54.70% to 37.50%), RR-TB (from 44.16% to 11.49%) and MDR-TB (from 26.90% to 10.34%) showed a significant downward trend from 2013 to 2020. Males (AOR 1.28, 95% CI 1.035–1.585), patients 45 to 64 years of age (AOR 1.75, 95% CI 1.342–2.284), patients 65 years and older (AOR 1.65, 95% CI 1.293–2.104), rural residents (AOR 1.24, 95% CI 1.014–1.519) and a previous treatment history (AOR 3.94, 95% CI 3.275–4.741) were risk factors for MDR-TB. Conclusion The prevalence of DR-TB, RR-TB and MDR-TB was significantly reduced from 2013 to 2020. Considerable progress has been made in the prevention and treatment of DR-TB during this period. However, the increasing rate of drug resistance in EMB and SM should be taken seriously. Suspected DR-TB patients who are male, older than 45 years of age, live in rural areas, and have a history of TB treatment should be given priority by health care providers.

Abstract
Diabetes mellitus (DM) has been frequently associated with an impaired immune response against infectious agents, making affected patients at risk for more severe disease and sometimes causing worse outcomes. The recent COVID-19 pandemic has seriously affected patients with both diabetes, in particular those carrying comorbidities or with poor glycemic control. As regards pediatric diabetes mellitus, the availability of more accurate and technological tools for glycemic management and the improved markers of metabolic control might mitigate the negative impact of infections. Notably, good metabolic control of diabetes since its diagnosis reduces not only the risk of microangiopathic complications but also of impaired immune response to infectious diseases. Therefore, vaccinations are strongly recommended. Our paper aims to provide the most updated evidence regarding infectious diseases in type 1 pediatric DM.

Abstract
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 26–45 years 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.

Abstract
Background Drug resistant tuberculosis (DR-TB) infringes substantial burden in terms of longer treatment duration, morbidity and mortality. Timely identification of patients at risks of DR-TB will aid individualized treatment. Current study was aimed to ascertain several factors associated with DR-TB among patients attending a tertiary care hospital. Methods This retrospective study was conducted among patients with confirmed diagnosis of DR-TB and drug susceptible TB (DS-TB) seeking medical care from a tertiary care hospital during 2014–2019. The types of DR-TB included were rifampicin resistant tuberculosis (RR-TB), Multidrug resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB). Appropriate statistical methods were implied to evaluate the factors associated with DR-TB. Results Out of 580 patients, DS-TB was diagnosed in 198 (34.1%) patients while DR-TB was present in 382 patients. Of resistance cases, RR-TB, MDR-TB and XDR-TB were diagnosed in 176 (30.3%), 195 (33.6%) and 11 (1.9%) patients, respectively. Significant differences (P < 0.05) in demographics and clinico-laboratory characteristics were observed between patients with DS-TB and DR-TB. Logistic regression analysis revealed age ≤38 years (OR: 2.5), single marital status (OR: 11.1), tobacco use (OR: 2.9), previous treatment (OR: 19.2), treatment failure (OR: 9.2) and cavity on chest X-ray (OR: 30.1) as independent risk factors for MDR-TB. However, XDR-TB was independently associated with age group of ≤38 years (OR: 13.6), students (OR: 13.0), previous treatment (OR: 12.5), cavity on chest X-ray (OR: 59.6). The independent risk factors associated with RR-TB are age ≤38 years (OR: 2.8), females (OR: 5.7), unemployed (OR: 41.5), treatment failure (OR: 4.9), previous treatment (OR: 38.2) and cavity on chest X-ray (OR: 4.3). ROC curve analysis accentuate the excellent predictive accuracy of all logistic regression models as shown by AUC (0.968, P < 0.001) for MDR-TB, AUC (0.941, P < 0.001) for XDR-TB and AUC (0.962, P < 0.001) for RR-TB. Conclusions Current study demonstrates a sizeable extent of resistant cases among pulmonary TB patients. This study presaged significant risk of DR-TB among females, young adults, unemployed, smokers, patients with previous treatment failure and cavitation on chest X-ray. Timely identification of high risk patients will give pronounced advantages regarding appropriate choices of prevention, treatment and disease control.

Abstract
Tuberculosis is a prime example of a social disease that requires social, economic and environmental interventions. However, research on social determinants of Multidrug-Resistant (MDR-TB) is limited. The five-stage scoping review showed the most common association of MDR-TB with multidimensional poverty (income, nutrition, education and social support) both as a contributing factor and a consequence of it. The review also found that physical environment (inadequate housing, overcrowding, poor physical environment, and smoking), health care needs, cultural determinants (race, ethnicity and gender), comorbidities had a strong influence on the development and transmission of MDR-TB. Since, epidemiology and care for MDR-TB are greatly influenced by socioeconomic factors, social, environmental and economic actions are needed in addition to the implementation of novel diagnostic techniques and treatments.

Abstract
Introducción. Se estima que el tratamiento para la tuberculosis multidrogorresistente (TB-MDR) fracasa en el 46% de los pacientes, situación que representa una crisis para la salud pública. En Perú, 6 personas se enferman de tuberculosis (TB) cada hora y de los 27 000 casos notificados de enfermedad activa por año, el 10% corresponde a TB-MDR.Objetivo. Determinar la distribución geográfica de la TB-MDR y los factores de riesgo de esta enfermedad en la región de Junín, ubicada en el centro de Perú. Materiales y métodos. Estudio longitudinal retrospectivo de casos y controles que incluyó 3 602 personas con diagnóstico de tuberculosis confirmado con cultivo positivo para Mycobacterium tuberculosis entre enero y diciembre de 2016. Los casos fueron los pacientes con diagnóstico de TB-MDR y los controles, los demás pacientes.Resultados. Se encontró una mayor prevalencia de casos de TB-MDR en la selva central de Perú, zona con alta incidencia de TB. Al realizar el análisis multivariado, se encontraron los siguientes factores de riesgo de multidrogorresistencia: antecedente de tratamiento de la TB (OR: 1.61, IC95%: 1.14-3.26), fracaso del tratamiento previo (OR: 5.84, IC95%: 4.03-8.21) y contacto intradomiciliario con personas con TB-MDR (OR: 91.57, IC95%: 34.56-289.14).Conclusiones. La distribución geográfica de la TB-MDR es de tipo no heterogéneo con alta incidencia en la selva central. En pacientes con diagnóstico reciente de TB, se debe considerar la posibilidad de TB-MDR si presentan alguno de los factores de riesgo identificados aquí y proceden de alguna zona de alta prevalencia de esta enfermedad.

Drug sensitivity patterns in Xpert-positive spinal tuberculosis: an observational study of 252 patients. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2020; 29:1476-1482. [PMID: 32055960 DOI: 10.1007/s00586-020-06305-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 12/31/2019] [Accepted: 01/18/2020] [Indexed: 10/25/2022]
Abstract
PURPOSE To evaluate the sensitivity patterns of anti-tubercular drugs in Xpert MTB-positive spinal tuberculosis (TB) patients and to formulate the guidelines for early start of empiric anti-tubercular treatment (ATT) in MDR-TB spine based on resistance pattern in this large series. METHODS It was a cross-sectional observational study of 252 consecutive patients who were Xpert MTB-proven spinal TB cases with retrospective analysis of prospective data. The Xpert MTB/RIF (Mycobacterium tuberculosis/rifampicin) assay was used to diagnose spinal TB and RIF resistance. All patients underwent drug sensitivity testing (DST) to 13 commonly used anti-tubercular drugs using BACTEC MGIT-960 system. The drug sensitivity pattern of primary and secondary anti-tubercular drugs was recorded and compared. RESULTS The DST study revealed 110 (43.6%) cases of multi-drug resistant (MDR-resistance to both isoniazid and rifampicin) and 24 (9.5%) cases of non-MDR-TB spine. The widespread resistance was found for both isoniazid (91%) and rifampicin (85%), followed by streptomycin (61.9%). The least resistance was found for kanamycin, amikacin and capreomycin and no resistance found for clofazimine. CONCLUSION The Xpert MTB/RIF assay is an efficient technique for the rapid diagnosis of spinal TB and suspected MDR-TB; however, it is recommended to do culture and DST in all patients with spinal TB to guide the selection of appropriate second-line drugs when required. In cases of non-availability of culture and DST, it is suggested to use data from large series such as this to plan the best empirical ATT regimen.

Abstract
Ethiopia is one of 30-high burden multidrug-resistant tuberculosis (MDR-TB) countries globally. The aim of this study was to describe the characteristics of patients with MDR-TB and to investigate risk factors for MDR-TB relative to having drug-susceptible tuberculosis (TB), in northwest Ethiopia. A hospital-based, unmatched case-control study was conducted. Cases were all MDR-TB patients (i.e., resistant to at least rifampicin and isoniazid) who were confirmed by culture and drug-susceptibility testing whilst enrolled on treatment at Gondar University Hospital. Controls were all drug-susceptible tuberculosis (DS-TB) patients who were confirmed by Gene Xpert MTB/RIF at Gondar University Hospital. Univariable and multivariable logistic regression models were used for comparisons, and odds ratios with 95% confidence intervals (CI) were computed to measure the strength of association between the dependent and independent variables. A total of 452 patients (242 MDR-TB and 210 DS-TB) were included in this study. The mean age of the study participants was 33 years (SD ± 14 years). Approximately one-fifth (78, 17%) of all study participants were human immunodeficiency virus (HIV) positive; 21% (51) of cases and 13% (27) of controls. Risk factors associated with MDR-TB were a history of previous TB treatment (Adjusted Odds Ratio (AOR): 83.8; 95% CI: 40.7, 172.5), low educational status (AOR: 5.32; 95% CI: 1.43, 19.81); and ages less than 20 years (AOR: 9.01; 95% CI: 2.30, 35.25) and 21-30 years (AOR: 2.61; 95% CI: 1.02, 6.64). HIV infection was also significantly associated with MDR-TB among new TB patients (AOR: 5.55; 95% CI: 1.17, 26.20). This study shows that clinical and demographic features can be used to indicate higher risks of drug resistance in this setting.

Tegegne BS, Mengesha MM, Teferra AA, Awoke MA, Habtewold TD. Association between diabetes mellitus and multi-drug-resistant tuberculosis: evidence from a systematic review and meta-analysis. Syst Rev 2018; 7:161. [PMID: 30322409 PMCID: PMC6190557 DOI: 10.1186/s13643-018-0828-0] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 10/01/2018] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Diabetes mellitus (DM) poses a significant risk for the development of active tuberculosis (TB) and complicates its treatment. However, there is inconclusive evidence on whether the TB-DM co-morbidity is associated with a higher risk of developing multi-drug-resistant tuberculosis (MDR-TB). The aim of this meta-analysis was to summarize available evidence on the association of DM and MDR-TB and to estimate a pooled effect measure. METHODS PubMed, Excerpta Medica Database (EMBASE), Web of Science, World Health Organization (WHO), and Global Health Library database were searched for all studies published in English until July 2018 and that reported the association of DM and MDR-TB among TB patients. To assess study quality, we used the Newcastle-Ottawa Scale for cohort and case-control studies and the Agency for Healthcare Research and Quality tool for cross-sectional studies. We checked the between-study heterogeneity using the Cochrane Q chi-squared statistic and I2 and examined a potential publication bias by visual inspection of the funnel plot and Egger's regression test statistic. The random-effect model was fitted to estimate the summary effects, odds ratios (ORs), and 95% confidence interval (CIs) across studies. RESULTS This meta-analysis of 24 observational studies from 15 different countries revealed that DM has a significant association with MDR-TB (OR = 1.97, 95% CI = 1.58-2.45, I2 = 38.2%, P value for heterogeneity = 0.031). The significant positive association remained irrespective of country income level, type of DM, how TB or DM was diagnosed, and design of primary studies. A stronger association was noted in a pooled estimate of studies which adjusted for at least one confounding factor, OR = 2.43, 95% CI 1.90 to 3.12. There was no significant publication bias detected. CONCLUSIONS The results suggest that DM can significantly increase the odds of developing MDR-TB. Consequently, a more robust TB treatment and follow-up might be necessary for patients with DM. Efforts to control DM can have a substantial beneficial effect on TB outcomes, particularly in the case of MDR-TB. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42016045692 .

Prevalence of Multidrug-Resistant Tuberculosis and Associated Factors in Ethiopia: A Systematic Review. J Pathog 2018; 2018:7104921. [PMID: 29850257 PMCID: PMC5903304 DOI: 10.1155/2018/7104921] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2017] [Revised: 02/22/2018] [Accepted: 02/28/2018] [Indexed: 11/24/2022] Open
Abstract
Background Multidrug-resistant tuberculosis (MDR-TB) has continued to be a challenge for tuberculosis (TB) control globally. Ethiopia is one of the countries with high MDR-TB burden. Objective The main purpose of this study was to determine the prevalence of MDR-TB and associated factors in Ethiopia. Methods A systematic review of the literatures on prevalence of MDR-TB and associated factors was conducted in the country. Results In our electronic search, 546 citations were depicted. Among the total 546 citations described, a total of 22 articles met eligibility criteria and were included in the review article. According to our review, the prevalence of MDR-TB ranged from 0 to 46.3%. The average mean rate of MDR-TB in Ethiopia was found to be 12.6 ± 15.9%. The overall prevalence of MDR-TB in all TB cases was estimated to be 1.4%. From a total of 3849 patients studied, 527 had MDR-TB. Previous exposure to antituberculosis treatment was the most commonly identified risk factor of MDR-TB in Ethiopia. Conclusion Despite relative decline in incidence of MDR-TB, the distribution and prevalence of MDR-TB continued to be a serious challenge for TB control in Ethiopia. Previous exposure to antituberculosis treatment was also the most common risk factor for MDR-TB. Therefore, strong TB and MDR-TB treatment along with tight introduction of follow-up strategies should be applied for better TB control.

Abstract
OBJECTIVES The aim of this study was to describe the secular trends in drug-resistant tuberculosis (DR-TB) and to identify unique characteristics of multidrug-resistant tuberculosis (MDR-TB) in rural China. METHODS A retrospective study was conducted using TB data collected from 36 TB prevention and control institutions serving rural populations in Shandong Province, China, for the period 2006-2015. RESULTS Approximately 8.3% of patients suffered from MDR-TB, among whom 70% were newly treated patients; this rate increased by 1.3% annually during the 10-year study period. An increase in the percentage of overall first-line drug resistance against isoniazid, rifampicin, ethambutol, and streptomycin was confirmed (p<0.05). The percentage of MDR-TB in new and previously treated cases increased at yearly rates of 9.9% and 11.1%, respectively. MDR-TB patients were more likely to be female (odds ratio (OR) 1.58, 95% confidence interval (CI) 1.32-1.89), smokers (OR 1.75, 95% CI 1.47-2.07), to have had recent TB contact (OR 1.58, 95% CI 1.04-2.42), or to have been retreated (OR 2.89, 95% CI 2.46-3.41). CONCLUSIONS Increasing MDR-TB and rates of primary MDR-TB characterize DR-TB cases in rural China. Persistent efforts need to be made among MDR-TB patients in future TB control strategies.

Sociodemographic correlates of HIV drug resistance and access to drug resistance testing in British Columbia, Canada. PLoS One 2017; 12:e0184848.

Abstract
Sociodemographic correlates of engagement in human immunodeficiency virus (HIV) care are well studied, however the association with accessing drug resistance testing (DRT) and the development of drug resistance have not been characterized. Between 1996-2014, 11 801 HIV patients accessing therapy in British Columbia were observed longitudinally. A subset of 9456 patients had testable viral load; of these 8398 were linked to census data. Sociodemographic (census tract-level) and clinical (individual-level) correlates of DRT were assessed using multivariable General Estimating Equation logistic regression adjusted odds ratios (aOR). The mean number of tests per patient was 2.1 (Q1-Q3; 0-3). Separately, any drug resistance was determined using IAS-USA (2013) list for 5703 initially treatment naïve patients without baseline resistance; 5175 were census-linked (mean of 1.5 protease-reverse transcriptase sequences/patient, Q1-Q3; 0-2). Correlates of detecting drug resistance in this subset were analyzed using Cox PH regression adjusted hazard ratios (aHR). Our results indicate baseline CD4 <200 cells/μL (aOR: 1.5, 1.3-1.6), nRTI-only baseline regimens (aOR: 1.4, 1.3-1.6), and unknown (therapy initiation before routine pVL in BC) baseline pVL (aOR: 1.8, 1.5-2.1) were among individual-level clinical covariates strongly associated with having accessed DRT; while imperfect adherence (aHR: 2.2, 1.9-2.5), low baseline CD4 count (aHR: 1.9, 1.6-2.3), and high baseline pVL (aHR: 2.0, 1.6-2.6) were associated with a higher likelihood of developing drug resistance. A higher median income (aOR: 0.83, 0.77-0.89) and higher percentage of those with aboriginal ancestry (aOR: 0.85, 0.76-0.95) were census tract-level sociodemographic covariates associated with decreased access to DRT. Similarly, aboriginal ancestry (aHR: 1.2, 1.1-1.5) was associated with development of drug resistance. In conclusion, clinical covariates continue to be the strongest correlates of development of drug resistance and access to DRT for individuals. Regions of high median income and high aboriginal ancestry were weak census-level sociodemographic indicators of reduced DRT uptake, however high aboriginal ancestry was the only sociodemographic indicator for development of drug resistance.

Abstract
The various aspects of MDR-TB, type of pathogen, different drug sensitive methods and mutation (s) in specific genes were determined. The histone-like protein (hupB) gene of M. tuberculosis was targeted by using primer sets: N & S and M & S (produced 645 bp & 318 bp fragment respectively). The most significant risk factors were the poverty and male gender of ages 11-25 years. All samples were detected as M. tuberculosis. By Drug Proportion method, the highest percentage (37%) was found resistant to only Rifampin. By MGIT method, the highest percentage (82.2%) was found resistant with the triple combination (Rifampin-RIF + Isoniazid-INH + Ethambutol-EMB) of the drugs. The highest mutations (76.92%) were found in gene rpoB (codon 531) in MDR TB patients. By, MAS-PCR, the highest percentage (34%) were found resistant to combination (INH + RIF) of the drugs. Minimum samples were resistant to RIF and RIF + INH drugs by MGIT, while proportionate results were observed from MAS-PCR and DP. Moreover, by MAS-PCR mutation in gene embB (306) caused EMB resistance (51.64%). We found that M. tuberculosis was the main cause of MDR-TB. Our findings may further be used for an early diagnosis of multi-drug resistant tuberculosis.

Abstract
The high prevalence of diabetes mellitus (DM) among multidrug resistant tuberculosis (MDR-TB) patients is a serious cause for concern. We conducted a meta-analysis to determine whether DM is an independent risk factor for MDR-TB. Electronic literature searches of the PubMed, Web of Science and EMBASE databases up to July 12, 2016 were conducted. The pooled adjusted odds ratio (OR) and 95% confidence intervals (CIs) were calculated using the random effects model with STATA 12.0 software. In total 13 studies, including 9289 individuals with TB, were included in this meta-analysis. Significant association between DM and MDR-TB (OR = 1.71; 95% CI = 1.32, 2.22) was identified. Subgroup analyses showed that: 1) Pooled OR was 1.25 (95% CI: 0.82-1.91) for cross-sectional studies, and was 2.14 (95% CI: 1.51-3.02) for longitudinal studies; 2) The pooled OR was 1.69 (95% CI:1.09-2.62) for primary MDR-TB, 1.94 (95% CI:1.42-2.65) for any MDR-TB, and 0.85 for secondary MDR-TB (95% CI: 0.29-2.54); 3) DM was significantly associated with MDR-TB in both Caucasian (OR = 2.26, 95% CI: 1.66-3.07) and Asian (OR = 1.40, 95% CI: 1.01-1.95) subgroups. No evidence of publication bias was identified. In conclusion, the pooling analysis indicated that DM was an independent risk factor for MDR-TB, especially for primary MDR-TB.

Abstract
Background Understanding the geographical distribution of multidrug-resistant tuberculosis (MDR-TB) in high TB burden countries such as Ethiopia is crucial for effective control of TB epidemics in these countries, and thus globally. We present the first spatial analysis of multidrug resistant tuberculosis, and its relationship to socio-economic, demographic and household factors in northwest Ethiopia. Methods An ecological study was conducted using data on patients diagnosed with MDR-TB at the University of Gondar Hospital MDR-TB treatment centre, for the period 2010 to 2015. District level population data were extracted from the Ethiopia National and Regional Census Report. Spatial autocorrelation was explored using Moran’s I statistic, Local Indicators of Spatial Association (LISA), and the Getis-Ord statistics. A multivariate Poisson regression model was developed with a conditional autoregressive (CAR) prior structure, and with posterior parameters estimated using a Bayesian Markov chain Monte Carlo (MCMC) simulation approach with Gibbs sampling, in WinBUGS. Results A total of 264 MDR-TB patients were included in the analysis. The overall crude incidence rate of MDR-TB for the six-year period was 3.0 cases per 100,000 population. The highest incidence rate was observed in Metema (21 cases per 100,000 population) and Humera (18 cases per 100,000 population) districts; whereas nine districts had zero cases. Spatial clustering of MDR-TB was observed in districts located in the Ethiopia-Sudan and Ethiopia-Eritrea border regions, where large numbers of seasonal migrants live. Spatial clustering of MDR-TB was positively associated with urbanization (RR: 1.02; 95%CI: 1.01, 1.04) and the percentage of men (RR: 1.58; 95% CI: 1.26, 1.99) in the districts; after accounting for these factors there was no residual spatial clustering. Conclusion Spatial clustering of MDR-TB, fully explained by demographic factors (urbanization and percent male), was detected in the border regions of northwest Ethiopia, in locations where seasonal migrants live and work. Cross-border initiatives including options for mobile TB treatment and follow up are important for the effective control of MDR-TB in the region.

Abstract
INTRODUCTION Multi-drug-resistant tuberculosis (MDR-TB) has emerged as a challenge to global tuberculosis (TB) control and remains a major public health concern in many countries. Diabetes mellitus (DM) is an increasingly recognized comorbidity that can both accelerate TB disease and complicate its treatment. The aim of this study is to summarize available evidence on the association of DM and MDR-TB among TB patients and to provide a pooled estimate of risks. METHODS All studies published in English before October 2016 will be searched using comprehensive search strings through PubMed, EMBASE, Web of Science, and WHO Global Health Library databases which have reported the association of DM and MDR-TB in adults with TB (age > =15). Two authors will independently collect detailed information using structured data abstraction form. The quality of studies will be checked using Newcastle-Ottawa Scale for cohort and case-control studies and the Agency for Healthcare Research and Quality tool for cross-sectional studies. Heterogeneity between included studies will be assessed using the I2 statistic. We will check potential publication bias by visual inspection of the funnel plot and Egger's regression test statistic. We will use the random effects model to compute a pooled estimate. DISCUSSION Increases in the burden of non-communicable diseases and aging populations are changing the importance of different risk factors for TB, and the profile of comorbidities and clinical challenges for people with TB. Although classic risk factors and comorbidities such as overcrowding, under-nutrition, silicosis, and HIV infection are crucial to address, chronic conditions like diabetes are important factors that impair host defenses against TB. Thus, undertaking integrated multifaceted approach is remarkably necessary for reducing the burden of DM and successful TB treatment outcome. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42016045692 .

Abstract
Background Drug-resistant tuberculosis (TB) is a significant public health problem. Greater than 90% of rifampicin (RIF)-resistant isolates were also isoniazid resistant, and hence, rifampicin resistance (RR) is frequently used as a surrogate for multidrug-resistant TB. Setting This study was conducted at Infectious Disease Hospital Kano in North-Western Nigeria. Objectives The aim of this study was to determine the prevalence of RR among patients previously treated for pulmonary TB (PTB). Materials and Methods A total of 120 patients previously treated for PTB with current clinical features of PTB were recruited into this study. Relevant clinical information were obtained using a questionnaire. The sputum was collected and analyzed by the Gene Xpert MTB/RIF® machine to detect RR tuberculosis infection and blood screened for HIV infection. Results The mean (±standard deviation) age of the participants was 35.9 ± 14.3 years and they comprised 73 (60.8%) males and 47 (39.2%) females. HIV-seropositive rate was 11.7% among the participants. Of the 120 participants, PTB was detected in 35 (29.2%) of the participants by Gene Xpert MTB/RIF and 29 of them were cases of relapse. Five patients (4.2%) had RR tuberculosis and 80% of them were below the age of 45 years. Conclusion The prevalence of RR is not high among previously treated PTB patients in this study when compared with other previous studies. This finding is a window for evaluating the efficacy of current interventions in the region and evidence for the consolidation of existing control policies.

Abstract
INTRODUCTION The emergence of multi-drug resistant tuberculosis (MDR-TB) has become a major public health concern that threatens advances made in global TB control efforts. Though the problem is prevalent, it did not receive major attention to generate supportive evidence for the prevention and control of MDR-TB. The aim of this study was to identify predictors of MDR-TB in a national TB referral centre in Ethiopia. METHODS An unmatched, case-control study was conducted at St. Peter Hospital to assess risk factors associated with MDR-TB. The study included 103 culture proven, MDR-TB patients referred to the hospital during the study period (cases) and 103 randomly-selected TB patients with confirmed TB who turned negative after treatment (controls). Regressions analyses were used to determine the association of variables. RESULTS The mean age among cases and controls was 30.5 (±9.26) and 34.73 (±11.28) years, respectively. The likelihood of having MDR-TB was 20.3 times higher among those who had a any previous history of TB treatment (AOR=20.3 [CI 5.13, 80.58]), 15.7 times higher among those who had TB more than once (AOR=15.7 [CI 4.18, 58.71]) compared those who had once, 6.8 times higher among those who had pulmonary TB (AOR=6.8 [CI 1.16, 40.17]) and 16.1 times higher for those who had experienced treatment with a Category II regimen (AOR=16.1 [CI 2.40, 108.56]). HIV infection was less common among cases than controls. CONCLUSION This study concluded that special attention should be given to patients with a history of the following: TB more than once, presence of pulmonary TB, and used a Category II treatment regimen, as these were all determining factors for MDR-TB. Thus, this study urges the development and implementation of well-planned and integrated strategies for MDR-TB control and prevention in Ethiopia.

Abstract
Introduction L'objectif de cette étude était de déterminer les facteurs de risque associés à la tuberculose multi résistance à Kinshasa en République Démocratique du Congo. Méthodes Il s'agissait d'une étude cas témoins. Les cas comprenaient tous les patients tuberculeux résistants à la rifampicine et à l'isoniazide notifiés à Kinshasa de janvier 2012 à juin 2013. Les témoins étaient les patients tuberculeux traités durant la même période que les cas et qui à la fin du traitement étaient déclarés guéris. Pour cette étude, nous avons obtenu une clairance éthique. Résultats L’échantillon était constitué de 213 participants dont 132 hommes (62%) et 81 femmes (38%). L’âge médian était de 31ans (16-73 ans). Les facteurs associés significatifs (p< 0,05) à la tuberculose multi résistante étaient le non-respect des heures de prise de médicaments (0R = 111) (80% chez les cas et 4% chez les témoins), l’échec au traitement (0R = 20) (76% chez les cas et 13% chez les témoins); la notion de tuberculose multi résistante dans la famille (0R = 6.4) (28% chez les cas et 6% chez les témoins); la méconnaissance de la tuberculose multi résistante (0R = 3.2) (31% chez les cas et 59% chez les témoins); un séjour en prison (0R = 7.6) (10% chez les cas et 1% chez les témoins) et l'interruption du traitement (0R = 6.1) ( 59% chez les cas et 19% chez les témoins). Conclusion L’émergence de la tuberculose multi résistante peut être évitée par la mise en place des stratégies de diagnostic et de traitement appropriées.

Abstract
The objectives of this study were to determine the impact of diabetes mellitus (DM) on antituberculosis drug resistance in new cases of tuberculosis (TB). A case-control study was conducted on all newly diagnosed pulmonary TB adult patients with DM as cases and without DM as controls who were hospitalised from May 2013 to October 2013 in Iran. A molecular resistance test for rapid detection of resistance to isoniazid and rifampicin was done. Multivariate analysis was performed to determine the impact of DM on any anti-TB drug resistance. In total, 62 TB cases with DM and 64 TB cases without DM were included. TB cases with DM were more likely to be older (59 years vs. 43 years; P=0.001). Two TB-DM patients had multidrug-resistant TB (MDR-TB) (3.2%) compared with no cases of MDR-TB in the control group, and more TB-DM cases had isolates that were resistant to at least one drug (12.9% vs. 10.9%). DM [odds ratio (OR)=4.82, 95% confidence interval (CI) 1-23.57], age <40 years (OR=5.48, 95% CI 1.19-25.29) and history of TB contact (OR=5.86, 95% CI 1.69-20.36) remained significantly associated with any drug resistance in the multivariate analysis. In conclusion, new TB patients with DM are at increased risk of anti-TB drug resistance. More studies are needed to confirm these results.

Abstract
To find out the reason why some people get infected directly with multidrug-resistant tuberculosis (MDR-TB), whereas some get infected with drug-susceptible tuberculosis (DS-TB), a 1:1:1 matched-pairs case-control study was conducted to identify predictors associated with primary MDR-TB and primary DS-TB against the control in Jiangsu Province, China. All three groups were geographically matched (by neighborhood) and matched on sex and age (±5 years). In total, 110 participants were enrolled in each of three matched groups. Conditional logistic regression analysis showed that predictors independently associated with primary MDR-TB were illiteracy or primary school education, annual per capita income ≤ US$2,000, per capita living space < 40 m2, and interval ≥ 7 days of eating fruits; predictors with primary DS-TB were body mass index ≤ 20 and feeling higher life pressure. This indicates that there are different predictors impacting the transmission range of primary MDR-TB and primary DS-TB in the general population.

Abstract
The objective of this study was to investigate the drug resistance characteristics of Mycobacterium tuberculosis isolates to four first-line antituberculous drugs (ATDs) from tuberculosis (TB) patients with AIDS in Beijing, China. All M. tuberculosis strains were isolated from specimens from TB patients with AIDS hospitalised between April 2010 and October 2012. Isolates were cultured by mycobacterial culture methods and were identified by multilocus PCR. Drug sensitivity testing was performed by the proportion method with the following first-line ATDs: isoniazid; rifampicin; streptomycin; and ethambutol. Results were compared with the drug resistance status of M. tuberculosis strains isolated from TB patients without HIV infection in Beijing. Among 41 M. tuberculosis isolates from TB patients with AIDS, the rates of total drug resistance (58.5%), initial drug resistance (46.7%) and acquired drug resistance (90.9%) were significantly higher than in TB patients without HIV infection (34.1%, 24.5% and 48.5%, respectively; P<0.05). In TB patients with AIDS, the rates of acquired drug resistance (90.9%) and acquired multidrug-resistant TB (MDR-TB) (54.5%) were significantly higher than the rates of initial drug resistance (46.7%) and initial MDR-TB (10.0%) (P<0.05). In patients with TB without HIV infection, the rate of acquired drug resistance (48.5%) was significantly higher than the rate of initial drug resistance (24.5%) (P<0.05). M. tuberculosis drug resistance in TB patients with AIDS is significantly more serious than in TB patients without HIV infection. These results showed that more attention should be paid to M. tuberculosis drug resistance in AIDS patients.

Abstract
The emergence of drug-resistant tuberculosis (TB), particularly multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB, is a major public health problem. The purpose of this review is to describe the current status of MDR-TB and factors that increase the risk of this infection. We conducted a systematic review of the literature on MDR-TB in Ethiopia. Out of 766 articles, 23 were found to meet eligibility criteria and included in this review. Among the 23 papers, six of them reported high prevalence of MDR-TB in the range of 3.3%-46.3%. Likewise, two studies reported XDR-TB in the range of 1% - 4.4% in Ethiopia. The most powerful predictor of the emergence of MDR-TB reported in Ethiopia is previous exposure to anti-TB drug treatment. This review indicated that MDR-TB in Ethiopia is a serious public health problem that needs to be addressed urgently. Strengthening early case detection and proper treatment of drug-susceptible TB in accordance with World Health Organization (WHO) treatment guidelines to ensure adequate treatment success rates is critical. Consequently, efforts have been made to a rapidly increase MDR-TB diagnosis as well as the number of treatment sites to implement a directly observed treatment, short-course (DOTS) plus strategy to interrupt transmission of MDR-TB.

Abstract
Objective To determine the risk factors for developing multidrug resistant tuberculosis in Bangladesh. Methods This case-control study was set in central, district and sub-district level hospitals of rural and urban Bangladesh. Included were 250 multidrug resistant tuberculosis (MDR-TB) patients as cases and 750 drug susceptible tuberculosis patients as controls. We recruited cases from all three government hospitals treating MDR-TB in Bangladesh during the study period. Controls were selected randomly from those local treatment units that had referred the cases. Information was collected through face-to-face interviews and record reviews. Unadjusted and multivariable logistic regression were used to analyse the data. Results Previous treatment history was shown to be the major contributing factor to MDR-TB in univariate analysis. After adjusting for other factors in multivariable analysis, age group “18–25” (OR 1.77, CI 1.07–2.93) and “26–45” (OR 1.72, CI 1.12–2.66), some level of education (OR 1.94, CI 1.32–2.85), service and business as occupation (OR 2.88, CI 1.29–6.44; OR 3.71, CI 1.59–8.66, respectively), smoking history (OR 1.58, CI 0.99–2.5), and type 2 diabetes (OR 2.56 CI 1.51–4.34) were associated with MDR-TB. Previous treatment was not included in the multivariable analysis as it was correlated with multiple predictors. Conclusion Previous tuberculosis treatment was found to be the major risk factor for MDR-TB. This study also identified age 18 to 45 years, some education up to secondary level, service and business as occupation, past smoking status, and type 2 diabetes as comorbid illness as risk factors. National Tuberculosis programme should address these risk factors in MDR-TB control strategy. The integration of MDR-TB control activities with diabetes and tobacco control programmes is needed in Bangladesh.

Abstract
BACKGROUND India is one of the high tuberculosis (TB)-burden countries in the world. Resistance to anti-tuberculosis (anti-TB) drugs has already become an important and alarming threat in most of the regions worldwide. India ranks second in the world in harbouring multi-drug resistant cases (MDRTB). Prevalence of MDR-TB mirrors the functional state and efficacy of TB control programmes and realistic attitude of the community towards implementation of such programmes. The most important risk factor in the development of MDRTB is improper implementation in the guidelines in the management of TB, and high rate of defaults on the part of the patients. The study was carried out to evaluate the drug resistance pattern to first line anti-TB drugs in Northern Karnataka region, India. MATERIALS AND METHODS A prospective study was conducted at J. N. Medical College and its associated Hospitals, Belgaum. Between January 2011 and December 2012, 150 sputum samples of suspected pulmonary TB patients based on the history were examined for the AFB culture by Lowenstein-Jensen (LJ) culture technique. A total of two early morning samples were collected for the smear [Ziehl-Neelsen (ZN) staining] and culture methods. It was observed that ZN staining for AFB was positive in 113 patients (75%), while AFB culture by LJ medium yielded growth in 66 cases (44%). Thus, a total of 66 AFB culture-positive samples by LJ medium were subjected for AFB drug-sensitivity testing (DST). DST was done for Isoniazid (INH), Rifampicin (RIF), Pyrazinamide (PZA), Ethambutol (EMB) and Streptomycin (SM) after isolation by using the resistance proportion method. RESULTS A total of 66 AFB culture-positive specimens, 20 (30.3%) cases were sensitive to all the five drugs while 46 (69.7%) cases showed resistance to one or more drugs. Among these, the resistance to rifampicin was highest (80.4%), while resistance to isoniazid, pyrazinamide, ethambutol and streptomycin were observed to be 60%, 58.7%, 52.1% and 63%, respectively. It was also observed that, resistance to all five drugs was highest (39.18%). MDR isolates were obtained in 52.2% of the cases. Illiteracy, low socio-economic status, previous history of TB and alcoholism were found to have statistically significant association for the development of MDR. CONCLUSIONS The prevalence of drug resistance in the present study was observed to be 69.7%. More than half of the cases were multi-drug resistant. The most common resistant pattern observed in this study was resistance to all the first-line drugs. Therefore, during initiation of new case proper explaining and completion of the treatment is very important to avoid the development of future drug resistance in the society.

Abstract
Multidrug-resistant tuberculosis (MDR-TB) poses a serious challenge to the global control of the disease. The purpose of this study was to characterize MDR-TB patients from Poland and to determine the extent of MDR-TB disease attributable to recent transmission. The study included all 46 patients diagnosed with MDR-TB in Poland in 2004 and followed up for 6 years (until 2011). For each patient, sociodemographic and clinical characteristics, treatment outcomes, and bacteriological data were collected by the review of medical and laboratory records. Mycobacterium tuberculosis isolates from all patients were characterized using spoligotyping, mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) typing, IS6110 restriction fragment length polymorphism (RFLP) analysis, and sequencing analysis of drug resistance-associated loci (katG, mabA-inhA, rpoβ, rpsL, and embB). The majority of patients were male (86.9%), 40-64 years of age (60.8%), with a history of TB treatment (84.8%), and producing smear-positive sputa (86.9%). Twenty-two (47.8%) patients suffered from concomitant diseases and 28 (60.8%) were alcohol abusers. Treatment outcome assessment revealed that 8 (17.4%) patients were cured or completed therapy, while 15 (32.6%) died of TB, 11 (23.9%) defaulted, 8 (17.4%) failed, and 1 (2.2%) was transferred and lost to follow-up. Upon genotyping, 10 (21.7%) isolates were allocated in four clusters. These were further subdivided by mutational profiling. Overall, in 6 (13%) patients, MDR-TB was a result of recent transmission. For 4 (8.7%) of these patients, a direct epidemiological link was established. The study shows that the transmission of MDR-TB occurs at a low rate in Poland. Of urgent need is the implementation of a policy of enforced treatment of MDR-TB patients in Poland.

Abstract
Multi-drug resistant tuberculosis (MDR-TB) represents a threat to health and development in countries with high TB burden. China’s MDR-TB prevalence rate of 6.8% is the highest in the world. Interventions to remove barriers against effective TB control, and prevention of MDR-TB are urgently needed in the country. This paper reports a cross-sectional questionnaire survey of 513 pulmonary TB (PTB) patients, and qualitative interviews of 10 healthcare workers (HCWs), and 15 PTB patients. The objective was to assess barriers against effective control of PTB and prevention of MDR-TB by elucidating the perspectives of patients and healthcare providers. Results showed that more than half of the patients experienced patient delay of over 12.5 days. A similar proportion also experienced detection delay of over 30 days, and delay in initiating treatment of over 31 days. Consulting a non-TB health facility ≥3 times before seeking care at TB dispensary was a risk factor for both detection delay [AOR (95% CI): 1.89(1.07, 3.34) and delay in initiating treatment[AOR (95% CI): 1.88 (1.06, 3.36). Results revealed poor implementation of Directly Observed Therapy (DOT), whereby treatment of 34.3% patients was never monitored by HCWs. Only 31.8% patients had ever accessed TB health education before their TB diagnosis. Qualitative data consistently disclosed long patient delay, and indicated that patient’s poor TB knowledge and socioeconomic barriers were primary reasons for patient delay. Seeking care and being treated at a non-TB hospital was an important reason for detection delay. Patient’s long work hours and low income increased risk for treatment non-adherence. Evidence-based measures to improve TB health seeking behavior, reduce patient and detection delays, improve the quality of DOT, address financial and system barriers, and increase access to TB health promotion are urgently needed to address the burgeoning prevalence of MDR-TB in China.

Abstract
Background Young children exposed to Mycobacterium tuberculosis have a high risk of disease progression following infection. This study aimed to determine risk factors for M. tuberculosis infection and disease in children following exposure to adults with multidrug-resistant (MDR) tuberculosis (TB). Methods Cross-sectional study; all children aged < 5 years, routinely referred per local guidelines to the provincial specialist MDR-TB clinic, Western Cape Province, South Africa, following identification as contacts of adult MDR-TB source cases, were eligible for enrolment from May 2010 through April 2011. Demographic, clinical and social characteristics were collected. All children underwent HIV and tuberculin skin testing. Results Of 228 children enrolled (median age: 30 months), 102 (44.7%) were classified as infected. Of these, 15 (14.7%) had TB disease at enrolment. Of 217 children tested for HIV, 8 (3.7%) were positive. In adjusted analysis, child’s age (AOR: 1.43; 95% CI: 1.13-1.91; p = 0.002) and previous TB treatment history (AOR: 2.51; 95% CI: 1.22-5.17; p = 0.01) were independent risk factors for infection. Increasing age of the MDR-TB source case (AOR: 0.67; 95% CI: 0.45-1.00; p = 0.05) was protective and source case alcohol use (AOR: 2.59; 95% CI: 1.29-5.22; p = 0.007) was associated with increased odds of infection in adjusted analysis. Decreasing age of the child (p = 0.01) and positive HIV status (AOR: 25.3; 95% CI: 1.63-393; p = 0.01) were associated with prevalent TB disease. Conclusion A high proportion of children exposed to MDR-TB are infected or diseased. Early contact tracing might provide opportunities to prevent the progression to TB disease in children identified as having been exposed to MDR-TB.

Abstract
Background There is a lack of information on the clinical characteristics of multidrug-resistant (MDR) tuberculosis (TB) and extensively drug-resistant (XDR) TB in the Jiangxi Province of China; furthermore, data have not been reported on the utility of mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) analyses in genotyping Mycobacterium tuberculosis strains isolated from this region. The aim of this study was to analyse the clinical features of patients with MDR and XDR TB from Jiangxi Province and to evaluate the discriminatory power of the 15-loci MIRU-VNTR method. Methods A retrospective study was conducted on patients diagnosed with MDR and XDR TB at the Jiangxi Chest Hospital from July 2010 to June 2011. The RD105 deletion-targeted multiplex PCR (DTM-PCR) and the 15-loci MIRU-VNTR method were used to determine the genetic background of the identified MDR and XDR M. tuberculosis clinical isolates. Results Of 804 M. tuberculosis clinical isolates, 159 (159/804, 19.8%) of the isolates were identified as MDR with first-line drug susceptibility testing. Of the 123 available MDR isolates, 13 (13/123, 10.6%) were XDR. The RD105 deletion-targeted multiplex PCR method identified 85 (85/110, 77.3%) MDR and 12 (12/13, 92.3%) XDR isolates as the Beijing genotype. MIRU-VNTR cluster analysis demonstrated that 101 MDR and 13 XDR strains had unique genotype patterns; the remaining 9 MDR strains were in 4 clusters, namely 1 cluster with 3 strains and 3 clusters with 2 strains, resulting in a low clustering rate (4.06%). The Hunter-Gaston discriminatory index (HGDI) of the 15-loci MIRU-VNTR method was as high as 0.992. In addition, clinical surveys showed that 87 (87/110, 79.1%) MDR TB patients and 10 (10/13, 76.9%) XDR TB patients had been previously treated. Diabetes mellitus was the most common comorbidity in both MDR TB (16/110, 14.5%) and XDR TB (2/13, 15.4%) patients. Conclusions Based on our preliminary data, the MDR and XDR M. tuberculosis clinical isolates identified at the Jiangxi Chest Hospital were genetically diverse and clustered at a low frequency. The 15-loci MIRU-VNTR method showed high discriminatory power and may be used as a first-line genotyping tool in investigating the molecular epidemiology of M. tuberculosis in Jiangxi, China. Decisive measures are urgently needed to effectively prevent and manage MDR and XDR tuberculosis in this province.

Abstract
BACKGROUND People who inject drugs (PWID) are at increased risk of tuberculosis (TB) and reduced retention in treatment. There is a need to document strategies for integrated delivery of HIV, TB and drug dependency care. METHODS This article reviews the literature on rates of TB mono- and co-infection, and published and grey literature descriptions of TB and HIV-TB care, among PWID. RESULTS Latent TB infection prevalence was high and active disease more common among HIV-positive PWID. Data on multidrug-resistant TB and co-infections among PWID were scarce. Models of TB care fell into six categories: screening and prevention within HIV-risk studies; prevention at TB clinics; screening and prevention within needle-and-syringe-exchange (NSP) and drug treatment programmes; pharmacy-based TB treatment; TB service-led care with harm reduction/drug treatment programmes; and TB treatment within drug treatment programmes. Co-location with NSP and opioid substitution therapy (OST), combined with incentives, consistently improved screening and prevention uptake. Small-scale combined TB treatment and OST achieved good adherence in diverse settings. Successful interventions involved collaboration across services; a client-centred approach; and provision of social care. No peer-reviewed studies described models of integrated HIV-TB care for PWID but grey literature highlighted key components: co-located services, provision of drug treatment, multidisciplinary staff training; and remaining barriers: staffing inefficiencies, inadequate funding, police interference, and limited OST availability. CONCLUSIONS Integration with drug treatment improves PWID engagement in TB services but there is a need to document approaches to HIV-TB care, improve surveillance of TB and co-infections among PWID, and advocate for improved OST availability.

Abstract
BACKGROUND Data on alcohol abuse as a risk factor for the development of multidrug-resistant tuberculosis (MDR-TB) are scarce. OBJECTIVE To describe the patterns of alcohol use in MDR-TB patients and to determine whether alcohol use is associated with the development of MDR-TB in Botswana. METHODS We compared the level of alcohol use among MDR-TB patients against three control groups: 1) non-MDR-TB patients, 2) human immunodeficiency virus (HIV) infected patients without a history of TB, and 3) the general population. Alcohol use and abuse was measured with the Alcohol Use Disorders Identification Test 10 (AUDIT) questionnaire. RESULTS Of a total national population of 164 MDR-TB cases, 114 (70%) were interviewed. MDR-TB cases had a lifetime prevalence of alcohol use of 35.1%, which was lower than that of all control groups (P < 0.001). MDR-TB cases had higher 1-month prevalence of alcohol dependence symptoms and a lower 1-year period prevalence of alcohol dependence symptoms (P < 0.01 and P = 0.01 respectively). Among patients with TB, alcohol abuse was found to be a risk factor for the development of MDR-TB. CONCLUSION MDR-TB patients in Botswana have high rates of alcohol use and abuse. Among TB patients, alcohol abuse is associated with the diagnosis of MDR-TB, and could be an important modifiable factor.

Abstract
Operations research (OR) is well established in India and is also a prominent feature of the global and local agendas for tuberculosis (TB) control. India accounts for a quarter of the global burden of TB and of new cases. Multidrug-resistant TB is a significant problem in Mumbai, India's most populous city, and there have been recent reports of totally resistant TB. Much thought has been given to the role of OR in addressing programmatic challenges, by both international partnerships and India's Revised National TB Control Programme. We attempt to summarize the major challenges to TB control in Mumbai, with an emphasis on drug resistance. Specific challenges include diagnosis of TB and defining cure, detecting drug resistant TB, multiple sources of health care in the private, public and informal sectors, co-infection with human immunodeficiency virus (HIV) and a concurrent epidemic of non-communicable diseases, suboptimal prescribing practices, and infection control. We propose a local agenda for OR: modeling the effects of newer technologies, active case detection, and changes in timing of activities, and mapping hotspots and contact networks; modeling the effects of drug control, changing the balance of ambulatory and inpatient care, and adverse drug reactions; modeling the effects of integration of TB and HIV diagnosis and management, and preventive drug therapy; and modeling the effects of initiatives to improve infection control.

Abstract
SETTING Alcohol use increases the risk of multidrug-resistant tuberculosis (MDR-TB) and poses challenges for successful MDR-TB treatment, including the potential for additional adverse events. AIM To investigate the association between alcohol consumption during MDR-TB treatment and adverse events and treatment outcomes in a cohort of patients in Tomsk, Russia. DESIGN From 2000 to 2004, retrospective data were collected on 407 MDR-TB patients in Tomsk. Factors associated with treatment outcomes were assessed using logistic regression. RESULTS Of the 407 patients, 253 (62.2%) consumed alcohol during treatment ('drinkers'), and 367 (90.2%) had at least one documented adverse advent. No significant differences were noted in frequency of adverse events in drinkers vs. non-drinkers. Drinkers had less favourable treatment outcomes (OR 0.28, 95%CI 0.18-0.45). Among drinkers, favourable treatment outcome was associated with adherence to at least 80% of prescribed doses (OR 2.89, 95%CI 1.30-6.43) and the occurrence of an adverse event requiring treatment interruption (OR 2.49, 95%CI 1.11-5.59). CONCLUSIONS Alcohol use did not appear to increase the risk of adverse events during MDR-TB treatment; however, alcohol consumption was associated with poor outcome. Our findings suggest that individuals who drink alcohol should receive aggressive attention to optimise treatment adherence and manage adverse events.

Abstract
The objective of this is quantitative, descriptive, retrospective and sectional study was to describe the sociodemographic and clinical-epidemiological profile of the patients with Multidrug-Resistant Tuberculosis (MRTB) enrolled in the State of São Paulo Reference Center for Tuberculosis (TB). Data was collected from notification forms and medical records of subjects registered between August 2002 and December 2009. Data collection was performed February to June 2010, using a structured instrument, and then systematized using Excel and Epi Info. It was identified 188 people, 74.2% from the municipality of São Paulo; 93.1% in the productive age group; 61.6% were unemployed; 64.4% men; 34.6% had 4 to 7 years of education; 98.9% with prior TB treatment; 98.4% with pulmonary MRTB; 71.4% with bilateral lesion cavity and all tested for antimicrobial sensitivity. The findings evidenced that subjects developed MRTB mainly due to living conditions and accessibility to health services. Insufficient data from notification forms and files limited an extensive approach as required by TB, a disease proven to be socially determined.

Abstract
The incidence and prevalence of diabetes mellitus (DM) is rapidly increasing across the globe. Tuberculosis (TB), meanwhile, remains a significant problem in low and middle income countries fuelled by high rates of HIV/AIDS. This article explores the long recognised but underappreciated connection between the two, revealing that DM makes a substantial contribution to the burden of incident TB around the world and may also worsen TB severity and treatment outcome. The dual management of the diseases may be challenging but must be addressed, both in low and high income settings, because the rising worldwide diabetes burden poses a threat to global TB control.

Abstract
Multidrug-resistant (MDR) tuberculosis (TB), or TB caused by strains of Mycobacterium tuberculosis resistant to at least isoniazid and rifampicin, represents a major threat to global TB control. Comprising more than 5% of all TB cases annually worldwide, these cases require treatment duration of 2 years on average with expensive and toxic second-line anti-TB drugs. Cure rates are far lower and mortality far higher than for drug-susceptible TB, particularly if patients are coinfected with HIV. Use of rapid diagnostic tools and assessment of risk factors for MDR TB, as well as rapid initiation of MDR TB treatment as recommended by the World Health Organization, including use of appropriate empiric regimens as necessary, is essential to achieving good outcomes from treatment. Rapid initiation of antiretroviral therapy (ART) for those with HIV coinfection, as well as strategic management of overlapping side effects from ART and first and second-line drugs for treating MDR TB to maintain patients on treatment are critical to patient survival and achieving good treatment outcomes. Employing sensible infection control practices in the context of diagnosis and treatment is essential to reducing transmission of MDR TB strains among patient populations and healthcare personnel.

Abstract
Background Drug resistance has been a cause of concern for tuberculosis (TB) control in both developed and developing countries. Careful monitoring of the patterns and trends of drug resistance should remain a priority. Methods Strains were collected from 1824 diagnosed sputum smear positive pulmonary TB patients in Jiangsu province of China and then tested for drug susceptibility against rifampicin, isoniazid, ethambutol and streptomycin. The prevalence and patterns of drug resistance in mycobacterium tuberculosis (MTB) isolates were investigated. Multiple logistic regression analysis was performed to identify the risk factors for multidrug resistant (MDR) bacterial infection. The strength of association was estimated by odds ratio (OR) and 95% confidence interval (95% CI). Results The drug susceptibility tests showed that 1077(59.05%) MTB strains were sensitive to all the four antibiotics and the other 747(40.95%) strains were resistant to at least one drug. The proportions of mono-drug resistance were 28.73% for isoniazid, 19.41% for rifampicin, 29.33% for streptomycin, and 13.98% for ethambutol, respectively. The prevalence of MDR-TB was 16.61%, which was significantly different between new cases (7.63%) and those with previous treatment history (33.07%). Geographical variation of drug resistance was observed, where the proportion of MDR-TB among new cases was higher in the central (9.50%) or north part (9.57%) than that in the south area (4.91%) of Jiangsu province. The age of patients was significantly associated with the risk of drug resistance (P < 0.001) and the adjusted OR (95% CI) was 1.88(1.26-2.81) for patients aged 35-44 years when compared with those 65 years or older. Patients with previous treatment history had a more than 5-fold increased risk of MDR-TB (adjusted OR: 6.14, 95% CI: 4.61-8.17), compared with those previously not having been treated. Conclusions The high prevalence of drug resistance has been a major challenge for TB control. Prevention and control of drug-resistant TB should be emphasized by the revised DOTS (direct observed therapy, short course) program through prompt case detection, routine and quality-assured drug susceptibility test for patients at high risk of resistance, programmatic treatment with both first and second-line medicines, and systematic treatment observation, with priority for high MDR-TB settings.

Abstract
Information about the changing epidemiology of drug-resistant tuberculosis (TB) in hospitals in China over the past decade remains largely unknown. This study examined the susceptibility patterns and trends of drug-resistant TB cases in the 309 Hospital in Beijing, China. Mycobacterium tuberculosis isolates were retrospectively identified, drug susceptibility test (DST) results and clinical data were analysed for the period 1997-2009. Of the 5523 culture-positive TB patients, 47·1% had resistance to any anti-TB drug, 14·8% had mono-resistant TB, 19·8% had poly-resistant TB, 19·4% had multidrug-resistant TB (MDR-TB), and 1·3% had extensively drug-resistant TB (XDR-TB). Drug-resistant TB was significantly associated with age group, residential situation, and TB treatment history (P<0·001). During 1997-2000, the percentage of TB patients with any resistance, mono-resistant TB, poly-resistant TB, MDR-TB and XDR-TB all increased significantly (P<0·001). During 2000-2003, the increasing trends of MDR-TB and XDR-TB cases were reversed. During 2004-2009, the percentage of TB patients with any resistance, mono-resistant TB, poly-resistant TB, MDR-TB and XDR-TB all declined significantly (P<0·001), but the prevalence of MDR-TB and poly-resistant TB cases remained high. Our study provides evidence demonstrating that intensive TB control measures have helped reverse the increasing trends of drug-resistant TB in China, but continuous surveillance of drug-resistant TB and better case management are still needed to further reduce the remaining high prevalence of drug-resistant TB.

Abstract
The link between diabetes mellitus and tuberculosis has been recognised for centuries. In recent decades, tuberculosis incidence has declined in high-income countries, but incidence remains high in countries that have high rates of infection with HIV, high prevalence of malnutrition and crowded living conditions, or poor tuberculosis control infrastructure. At the same time, diabetes mellitus prevalence is soaring globally, fuelled by obesity. There is growing evidence that diabetes mellitus is an important risk factor for tuberculosis and might affect disease presentation and treatment response. Furthermore, tuberculosis might induce glucose intolerance and worsen glycaemic control in people with diabetes. We review the epidemiology of the tuberculosis and diabetes epidemics, and provide a synopsis of the evidence for the role of diabetes mellitus in susceptibility to, clinical presentation of, and response to treatment for tuberculosis. In addition, we review potential mechanisms by which diabetes mellitus can cause tuberculosis, the effects of tuberculosis on diabetic control, and pharmacokinetic issues related to the co-management of diabetes and tuberculosis.
