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.

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 Mycobacterium tuberculosis 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 for acid-fast bacilli after two months of compliance to 1st line anti-tuberculous therapy were included after gaining informed consent. Specimens used for drug sensitivity testing 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: Fifty children, 32 male (64%) and 18 female (36%) were included 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, rifampicin resistance was highest at 33/50 (66%), and resistance to streptomycin and ethambutol were the lowest (6/50; 12%). There were 18 (36%) 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 general population regarding the importance of preventing TB household contact, especially amongst children. With the selected method used to identify mainly older children with drug resistance, the yield for drug-resistant TB was found to be high.

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.

The Relationship

Multidrug-resistant tuberculosis (MDR-TB) is becoming major public health issues in the world. Among the causes are history of previous TB treatment and increased co-infection of TB-HIV (Human Immunodeficiency Virus). This study aimed to identify the relationship between history of previous TB treatment and HIV status with MDR-TB. This is a case control study. The sample case was patients with MDR-TB, while sample control was patient who have drug-sensitive TB. Secondary data was obtained from patient medical records and laboratory results at Rotinsulu Pulmonary Hospital Bandung. Data were analyzed using chi-square. Multiple logistic regression was used to identify the dominant factor that influence the occurrence of MDR-TB. This study showed that the history of previous TB treatment was statistically significant with MDR-TB (p value= 0.001; OR= 18.889; 95% CI= 4.093-87.172) and it is the dominant factor that influence MDR-TB (p value= 0.0001; OR= 56.84; 95% CI= 6.9- 468.87). HIV infection at control group (who contracted drug-sensitive TB) was 26.1% (p value= 0.022). This finding suggested that HIV testing should be performed to each TB and MDR-TB patients and increased collaboration TB-HIV program between the other health care facilities should ensue. Drug sensitivity testing should be conducted at the start of TB treatment for patients with previous TB treatment and TB-HIV co-infection.

Abstract Background: The aim of this study was to investigate the epidemiological characteristics and profile of drug-resistant tuberculosis (DR-TB) among children with TB in Sichuan province of China.Methods: From January 2015 to December 2018, microbiological culture-confirmed child TB cases (aged<15 years old) were enrolled retrospectively. Epidemiological and clinical information from these cases, and the drug susceptibility testing (DST) results of the isolates were collected and analyzed.Results: Of 317 culture-confirmed child TB cases, 16.7% (53/317) were aged under 5 years old. 54.9% were Tibetans, and 31.9% had clear history of contact with TB patients. More than half (53.9%) weren’t vaccinated by Calmette–Guérin bacillus (BCG). 30% (n=95) were diagnosed as severe TB, and 92.4% (n=293) were new cases. The ratio of severe TB in BCG vaccinated group was significant lower than that observed in unvaccinated group (p<0.01). Significantly higher proportion of severe TB among Tibetans than Han child TB cases was observed in BCG unvaccinated group (p<0.01). The overall rate of DR-TB in this study was 24.3% (77/317) and 17 multidrug-resistant tuberculosis (MDR-TB) cases were identified with rate of MDR-TB at 5.4% (17/317). No XDR case was found. 13 out of 17 MDR-TB cases (76.4%) were Tibetan children. The ratio of any resistance to four first-line drugs identified were: INH, 15.5%; RIF, 9.1%; EMB, 0.6% and SM, 6.0%, respectively. More than half of MDR patterns were resistant to INH+RIF (9/17), followed by at least resistance to INH+RIF+SM (n=7). Conclusions: This was the first investigation on the epidemiological characteristics and profiles of DR-TB among child TB cases in Southwest of China. Our findings indicated a potentially high risk of TB infection to Tibetan children in the concentrated Tibetan communities of Sichuan.

Background: Drug Resistant Tuberculosis (DR-TB) is a major threat to the realization of the goal of a TB free world in the near future. It is important to study the reasons for the increasing number of such cases so that effective action can be taken to control this growing epidemic.Methods: Sputum from 36 patients diagnosed with acquired pulmonary Multidrug Resistant Tuberculosis (MDR-TB) were subjected to first- and second-line Drug Sensitivity Testing (DST) after liquid culture in mycobacterium growth Indicator Tube (MGIT). Primary MDR-TB cases were excluded. The relation of the drug sensitivity profile with the history of prior treatment taken was statistically analysed.Results: Majority of the patients had received appropriate treatment, and most had adhered to prescribed treatment. Among the 36 patients, 24(66.7%) were found to be Pre-Extensively Drug Resistant (Pre-XDR-TB) and 4(11.1%) were extensively drug resistant XDR-TB cases. Inappropriate prescription of fluoroquinolone (FQ) was found to be most common. Prior intake of any drug was not found to significantly affect subsequent resistance to that drug.Conclusions: Fluoroquinolone resistance is quite common in patients with DR-TB (66.7%). This study did not find the prior use of FQ or any other drug to significantly affect subsequent resistance to the drug. Primary drug resistance is thus a major concern. 11.1% patients were found to be XDR-TB cases. Hence DST for first- and second-line drugs should be done at the time of diagnosis to avoid failure of treatment with a predesigned regimen.

Introduction. The treatment of children with multidrug-resistant and extensively drug-resistant tuberculosis (MDR / XDR-TB) is a difficult task due to many factors: the duration of treatment, the lack of drugs with children’s dosages, age restrictions (according to the drug instructions).Purpose of the study. To assess the efficacy and safety of regimen with the inclusion of bedaquiline in children and adolescent with respiratory tuberculosis with drug-resistant tuberculosis.Materials and methods. The study is prospective, cohort, non-comparative from the period 2017–2019. We included 24 patients aged 5 to 17 years with MDR-TB (established or suspected) began regimen containing bedaquiline for 24 weeks. The duration of observation of patients included in the study was 24 months.Results. We can state a sufficient level of safety of using the latter for 24 weeks: adverse events presumably associated directly with the intake of bedaquiline were noted in only 1 patient out of 24 (4.2%; 95% CI 0.7-20.3). The efficacy of a regimen containing bedaquiline in combination with other anti-tuberculosis reserve drugs is beyond doubt: positive clinical and radiological dynamics and cessation of bacterial excretion by the end of the 24-week course of treatment were noted in all patients included in the study. In the course of 2-year follow-up, no exacerbation of the tuberculous process was observed in any case. All patients achieved clinical cure of tuberculosis.Conclusion. Regimen containing bedaquiline for children aged 5–17 years with multidrug-resistant tuberculosis is effective and safe.

Background: World Health Organization (WHO) estimates that there were 558000 new cases with resistance to Rifampicin, of which 82% had multidrug-resistant tuberculosis (MDR-TB). Objectives: We aimed to identify the prevalence of MDR-TB in River Nile state, Sudan, and the risk factors contributing to its occurrence. Methods: This was a descriptive cross-sectional hospital-based study involved 200 specimens taken from patients suspected of having MDR-TB tested using an automated GeneXpert assay. Results: Results of GeneXpert assay showed that the presence of Mycobacterium tuberculosis in 81 (40.5%), and out of 81 positive test results there were 13 (16%) had MDR-TB. Additionally, 7 cases of MDR-TB were previously treated which represented about (53%) of MDR patients, the remaining 6 MDR-TB patients were new cases and represented (47%) of MDR-TB patients. Moreover, there were 4 MDR-TB patients who had a history of contact with MDR-TB patients. Conclusion: Prevalence of MDR-TB in River Nile State, Sudan was 16%, which is greater than WHO estimation for Sudan (10.1%). The results revealed that the main risk factor to develop MDR-TB was a history of contact with MDR-TB, so adherence to treatment and social awareness about the spread of MDR-TB are crucial preventive measures.

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.

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.

MDR-TB (Multidrug-Resistant Tuberculosis) adalah salah satu jenis TB yang resisten dengan OAT (Obat Anti Tuberculosis) dengan resisten terhadap 2 obat anti tuberculosis yang paling ampuh yaitu rifampisin dan isoniazid. Obat rifampisin dan isoniazid sudah tidak efektif dalam membunuh kuman mycobacterium tuberkulosis dikarenakan kuman yang sudah resisten terhadap obat tersebut. MDR-TB merupakan suatu permasalahan yang menjadi hambatan utama dunia dalam pemberantasan TB. Tujuan dari penelitian ini adalah untuk mengidentifikasi faktor risiko apa saja yang dapat berpengaruh pada kejadian tuberkulosis dengan multidrug-resistant tuberculosis (MDR-TB) di RSUD Ulin Banjarmasin dengan variabel yang ditinjau adalah pengetahuan, motivasi dan keteraturan minum obat. Metode penelitian dengaan rancangan Cross Sectional dengan metode pengambilan dengan kuesioner. Populasi dalam penelitian ini adalah seluruh pasien dengan diagnosis tuberkulosis multidrug resistant tuberculosis (MDR-TB) dan pasien TB Non MDR yang digunakan sebagai pembanding yang dipilih secara acak. Hasil pada penelitian ini menunjukkan bahwa faktor risiko yang terbukti berpengaruh pada kejadian TB-MDR adalah keteraturan minum obat (p-value< 0,05). Oleh karena itu, untuk mengurangi potensi bertambahnya penderita TB-MDR, maka perlu diperhatikan lagi keteraturan minum obat penderita, memastikan agar penderita benar-benar rutin dan teratur dalam minum obat.  MDR-TB (Multidrug-Resistant Tuberculosis) is one of tuberculosis characterized by resistant to anti-TB drug (Anti Tuberculosis Drug). An MDR-TB event is a resistance event to 2 of the most effective anti-TB drugs which are rifampicin and isoniazid. Rifampicin and isoniazid are no longer effective in killing Mycobacterium tuberculosis bacteria due to its resistant to the drug. The purpose of this study is to identify any risk factors that can affect the incidence of tuberculosis with multidrug-resistant tuberculosis (MDR-TB) in RSUD Ulin Banjarmasin. The variables in this study were knowledge, motivation and regularity of taking drugs. The research method was a cross sectional design using questionnaire to the patients. The population in this study was all patients with a diagnosis of multidrug resistant tuberculosis (MDR-TB) and non-MDR TB patients who used as a comparison which were selected randomly. The results of this study indicate that the risk factor that has been shown to influence the incidence of MDR-TB was the regularity of taking medication (p-value <0.05). Therefore, to reduce the potential of MDR-TB sufferers to increase, it is necessary to pay attention to taking drug regularity of patient, ensuring that the patient is really routine and taking medication regularly.Keywords: RSUD Ulin Banjarmasin, MDR-TB (Multidrug-Resistant Tuberculosis), Tuberculosis
