Abstract This study is the first to report a clinical case of simultaneously acquired resistance to bedaquiline (BDQ) and delamanid (DLM). Whole genome sequencing revealed two nucleotide insertions (Rv0678 and fbiC) in the Mycobacterium tuberculosis isolate. The minimum inhibitory concentrations for BDQ and DLM were 0.25 µg/ml and >2.0 µg/ml, respectively.

AbstractWe report on the first six cases of acquired resistance to bedaquiline in Pakistan. Seventy sequential culture isolates from 30 drug-resistant tuberculosis patients on bedaquiline-containing regimen were tested for minimum inhibitory concentration (MIC) and whole genome sequencing. An increase in MICs associated with cross-resistance to clofazimine and appearance of specific mutations was documented in six cases. The study underlines that appropriate monitoring is mandatory for the introduction of new drugs.

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.
