ABSTRACTObjective: GenoType MTBDRplus line probe assay (LPA) is developed for performing drug susceptibility testing (DST) for Rifampicin (RIF) andisoniazid in sputum specimens from smear-positive pulmonary tuberculosis (TB) patients and revised national TB control Programme (RNTCP)has endorsed LPA for the diagnosis of multi drug resistant TB (MDR-TB). This study was conducted to assess the potential utility of LPA for MDR-TBpatient management.Methods: MDR-TB suspects under RNTCP PMDT criteria C referred from different districts in Delhi state were included in the study January 2013 toDecember 2014. Sputum specimens found acid-fast bacilli positive by fluorescent microscopy were processed for LPA.Results: Out of 3062 specimens, 2055 (67.1%) MDR-TB suspects were read as positive and specimens from 1007 (32.9%) suspects were read asnegative in sputum smear microscopy. Out of 2019 specimens valid LPA results, 1427 were found to be pan-sensitive, 280 were MDR-TB, 40 were RIFmonoresistant, 183 were Isoniazid (INH) monoresistant, and 89 specimens were found negative for Mycobacterium tuberculosis.Conclusion: Routine use of LPA can substantially reduce the time to diagnosis of RIF and/or INH-resistant TB and can hence potentially enable earliercommencement of appropriate drug therapy and thereby facilitate prevention of further transmission of drug resistant strains.Keywords: Multi drug resistant tuberculosis, Line probe assay, Rifampicin, Isoniazid.

Background. This study aims to evaluate GenoType MTBDRplusand GenoType MTBDRslfor their ability to detect drug-resistant tuberculosis in a Chinese population.Methods. We collected 112Mycobacteria tuberculosisstrains from Jiangsu province, China. The conventional DST and line probe assay were used to detect drug resistance to rifampicin (RFP), isoniazid (INH), ofloxacin (OFX), kanamycin (Km), and ethambutol (EMB).Results. The sensitivity and specificity were 100% and 50% for RFP and 86.11% and 47.06% for INH, respectively. The most common mutations observed in MTBDRpluswererpoBWT8 omission + MUT3 presence,katGWT omission + MUT1 presence, andinhAWT1 omission + MUT1 presence. For drug resistance to OFX, Km, and EMB, the sensitivity of MTBDRslwas 94.74%, 62.50%, and 58.82%, respectively, while the specificity was 92.59%, 98.81%, and 91.67%, respectively. The most common mutations weregyrAWT3 omission + MUT3C presence,rrsMUT1 presence,embBWT omission + MUT1B presence, andembBWT omission + MUT1A presence. Sequencing analysis found several uncommon mutations.Conclusion. In combination with DST, application of the GenoType MTBDRplusand GenoType MTBDRslassays might be a useful additional tool to allow for the rapid and safe diagnosis of drug resistance to RFP and OFX.

Multi Drug Resistant Tuberculosis

BACKGROUND Ethiopia is one of among thirty high burden countries of multi-drug resistant tuberculosis (MDR-TB) in the regions of world health organization. Contextual evidence on the emergence of the disease is limited at a program level. OBJECTIVE The aim of the study is to explore patient-provider factors that may facilitate the emergence of multi-drug resistant tuberculosis. METHODS We used a phenomenological study design of qualitative approach from June to July, 2015. We conducted ten in-depth interviews and 4 focus group discussions with purposely selected patients and providers. We designed and used an interview guide to collect data. Verbatim transcribes were exported to open code 3.4 for emerging thematic analysis. Domain summaries were used to support core interpretation. RESULTS The study explored patient-provider factors facilitating the emergence of multi-drug resistant tuberculosis. These factors as underlying, health system and patient-related factors. Especially, the a shows conflicting finding between having a history of discontinuing drug-susceptible tuberculosis and emergence of multi-drug resistant tuberculosis. CONCLUSIONS The patient-provider factors may result in poor early case identification, adherence to and treatment success in drug sensitive or multi-drug resistant tuberculosis. Our study implies the need for awareness creation about multi-drug resistant tuberculosis for patients and further familiarization for providers. This study also shows that patients developed multi-drug resistant tuberculosis though they had never discontinued their drug-susceptible tuberculosis treatment. Therefore, further studies may require for this discording finding.
