Patient’S Perception

Tuberculosis (TB) is an infectious disease which is transmitted by air. This disease damages the lungs and other organs in the human body. It is still one of the leading causes of morbidity and mortality despite the fact that it can be cured with adequate treatment. The emergence of multidrug resistant tuberculosis (MDR-TB) or extensively drug resistant (XDR-TB) is one of the challenges in our effort to control the disease complications. The aim of the study was to assess the Patient’s Perception on emergence of MDR and XDR-Tuberculosis in the Pulmonology Department of teaching Hospital.

Multidrug-resistant tuberculosis (MDR-TB) and lately, extensively drug-resistant TB (XDR-TB) are increasing global health concerns. Here, we present the genome sequences of two MDR-TB isolates from Myanmar, one of 27 countries with a high MDR-TB burden, and describe a number of mutations consistent with these being XDR-TB isolates.

INTRODUCTION: The emergence of multidrug-resistant tuberculosis (MDR-TB) and, more recently, extensively drug-resistant TB (XDR-TB) is widely considered a serious threat to global TB control. Over 400,000 new cases of MDR-TB occur each year and, although their rates are currently unknown, XDR-TB cases have been detected in every country where there is capacity to detect them (including Canada).METHODS: The present article provides a narrative overview of the various diagnostic options available for XDR-TB, including conventional tools and newer rapid tests for drug resistance. Available data suggest that automated liquid cultures are highly accurate and their use is rapidly expanding. Newly developed phenotypic tests include TK Medium (Salubris Inc, USA), microscopic-observation drug-susceptibility assay, FASTPlaque-Response bacteriophage assay (Biotec Laboratories Ltd, UK), colorimetric redox indicator methods and the microcolony method. These tests are usually cheaper but not always simple to perform, with some requiring high standards of biosafety and quality control. Among the newly developed phenotypic methods, reverse hybridization-based assays, referred to as line probe assays, represent a useful tool because of their superior accuracy and cost-effectiveness.CONCLUSIONS: To effectively address the threats of MDR-TB and XDR-TB, global initiatives are required to scale-up culture and drug susceptibility testing capacities, especially in high-burden countries where such capacity is scarce. In parallel, efforts are needed to expand the use of novel and emerging technologies (ie, molecular diagnostics) for the rapid determination of drug resistance.

AbstractObjectivesCycloserine is crucial in multidrug-resistant tuberculosis (MDR-TB) treatment. Although extensive research has been carried out on MDR-TB, most researchers have not treated cycloserine in much detail. Therefore, we evaluate the efficacy and safety of cycloserine and seek to clarify the role of cycloserine for treatment of simple MDR-TB, pre-extensively drug-resistant tuberculosis (pre-XDR-TB), and extensively drug-resistant tuberculosis (XDR-TB).Patients and methodsA retrospective observational study was performed in China. We determined the treatment outcome as the primary outcome for 144 cycloserine-treated and 181 cycloserine-nontreated patients according to the definitions of WHO. The proportion of patients with sputum-culture conversion and the frequency of adverse drug reactions related to cycloserine were assessed as well.ResultsAmong 325 MDR-TB patients, 144 were treated with cycloserine and 100 (69.4%) out of 144 successfully completed treatment. Compared with patients in non-cycloserine group, the hazard ratio of any unfavorable treatment outcome was 0.53 (95%CI: 0.35-0.81, P=0.003). Culture conversion rate at the intensive phase was similar whether cycloserine was administered or not (P=0.703). Of the 144 patients treated with cycloserine, a total of 16 (11.1%) patients experienced side-effects related to cycloserine, including 7 patients who discontinued cycloserine permanently.ConclusionsCycloserine could be an attractive agent to treat MDR-TB. Its safety profile warrants use in the most of MDR-TB cases. Cycloserine significantly improved the chance of favorable outcome for patients with simple MDR-TB but not pre-XDR-TB and XDR-TB. More aggressive regimens might be required for pre-XDR-TB or XDR-TB patients.

OBJECTIVE: To describe the extent of the problem of multidrug-resistant tuberculosis (MDR-TB) in Alberta and British Columbia from 1989 to 1998.DESIGN: A retrospective, population-based descriptive study of all notified MDR-TB cases in the context of all notified TB cases, all notified culture-positive TB cases and all notified drug-resistant TB cases.SETTING: Provinces of Alberta and British Columbia, and their TB registries.PATIENTS: All people with TB reported to the TB registries of Alberta and British Columbia between January 1, 1989 and June 30, 1998.MAIN OUTCOME MEASURES: Drug susceptibility testing was performed in all cases of culture-positive TB. Demographic, clinical and laboratory data on all cases of MDR-TB were recorded.RESULTS: Of 4606 notified cases of TB, 3553 (77.1%) were culture positive. Of these, 365 (10.3%) were drug resistant; of the drug-resistant cases, 24 (6.6%) were MDR. Most MDR-TB patients were foreign-born; of the four Canadian-born patients, two were infected while travelling abroad. Although foreign-born patients were significantly more likely to harbour drug-resistant strains, 14.3% versus 4.8%, respectively (P<0.001), among those who were harbouring a drug-resistant strain, the proportion of Canadian-born versus foreign-born patients with an MDR strain was the same (6.7% versus 6.6%, respectively). From 1994 to 1998 versus 1989 to 1993, the proportion of all drug-resistant strains that were MDR was greater (9.0% versus 4.3%, respectively), but the difference was not statistically significant. Isolates from 16 of the 24 MDR-TB cases had been archived. Each of these was fingerprinted and found to be unique. Most MDR-TB cases (88%) were respiratory. Of those tested for human immunodeficiency virus (n=17), only one was seropositive. MDR-TB was ‘acquired’ in 67% and ‘primary’ in 33% of cases. Eight (33%) of the MDR-TB cases received curative courses of treatment, six (25%) are still being treated, and the remainder have either died (five, 21%), transferred out (four, 17%) or become ‘chronic’ (one, 4%). No secondary case of MDR-TB has been identified in Alberta and British Columbia.CONCLUSIONS: Most MDR-TB in Alberta and British Columbia is imported. The proportion of all drug-resistant cases that are MDR appears to be increasing, but not because of disease acquired from recent contact with MDR-TB in Canada.

AbstractChina is one of the top 30 countries with high multidrug-resistant tuberculosis (MDR-TB) and rifampin-resistant tuberculosis (RR-TB) burden. Chongqing is a southwest city of China with a large rural population. A retrospective observational study has been performed based on routine tuberculosis (TB) surveillance data in Chongqing from 2010 to 2017. The MDR/RR-TB notification rate increased from 0.03 cases per 100,000 population in 2010 to 2.09 cases per 100,000 population in 2017. The extensively drug-resistant TB (XDR-TB) notification rate has increased to 0.09 cases per 100,000 population in 2017. There was a decreasing detection gap between the number of notified MDR/RR-TB cases and the estimate number of MDR/RR-TB cases among all notified TB cases. The treatment success rate of MDR/RR-TB was 50.66% in this period. The rate of MDR/RR-TB in new TB cases was 6.23%, and this rate in previously treated TB cases was 32.7%. Despite the progress achieved, the prevalence of MDR/RR-TB was still high facing challenges including detection gaps, the regional disparity, and the high risk for MDR/RR-TB in elderly people and farmers. Sustained government financing and policy support should be guaranteed in the future.
