Objective: Household contacts (HHCs) of persons with tuberculosis (TB) including rifampicin-resistant or multi-drug-resistant TB (RR/MDR-TB) are at risk for TB infection. We investigated whether index patient-level clinical and socio-demographic factors of persons with MDR-TB are associated with TB disease among their HHCs in Uganda.
Methods: We designed an unmatched case-control study. Cases were HHCs of persons with MDR-TB that had TB disease while controls were a random sample of HHCs of persons with MDR-TB that had no TB disease. The case-to-control ratio was 1:3. We identified the factors that significantly differed between the cases and controls in a multivariable binary logistic regression analysis and reported the odds ratio (OR) and 95% confidence interval (CI).
Results: We found similar demographic and clinical characteristics among the 11 cases and 33 controls. In a multivariable analysis, malnutrition was significantly associated with being a case than a control (adjusted OR 5.01; 95% CI 1.18-24.83).
Conclusion: Therefore, TB Control Programs should focus on identifying malnutrition among persons with MDR-TB and providing nutritional counseling and support to improve recovery, and potentially reduce household TB transmission and optimize treatment success. Additionally, rapid screening for TB and preventive therapy should be prioritized to reduce transmission.

This study investigated the characteristics and outcomes of drug-resistant tuberculosis patients in selected rural healthcare facilities in the Eastern Cape, South Africa. A retrospective review of clinical records from 456 patients, covering the period from January 2018 to December 2020, revealed a statistically significant relationship between DR-TB types and age groups (Chi-square statistic: 30.74, -value: 0.

In Ethiopia, extrapulmonary tuberculosis (EPTB) is a significant public health challenge, and drug resistance (DR) in EPTB is often overlooked. In a cross-sectional study conducted between August 2022 and October 2023, we aimed to explore the magnitude of phenotypic drug resistance and identify genetic mutations linked to resistance using 189 Mycobacterium tuberculosis (MTB) isolates cultured from extrapulmonary clinical specimens.

Tuberculosis is a highly infectious disease and it is a global threat in particular affecting people from developing countries. It is thought that nearly one-third of the global population lives with this causative bacterium in its dominant form. The spread of HIV and the development of resistance to both multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) aggravates the spread of the disease and needs novel drugs which combat this disease effectively.

Bedaquiline is a drug used for the treatment of multidrug-resistant TB in adults and children that is currently only commercially available in tablet form. The present study was aimed at preparing nanoemulsion (NE) of BDQ using natural vegetable oils to deliver BDQ. The optimisation of surfactant mixtures was undertaken using Design of Experiments (DoE), specifically an optimal mixture design.

Background: Early evaluation of culture conversion after 6-month treatment of multidrug-resistant tuberculosis (MDR-TB) is vital for outcome prediction. This study aims to merge the maximum lesion cross-sectional area observed via computed tomography (CT) imaging during treatment to predict therapeutic response.
Methods: We retrospectively involved MDR-TB patients who completed 6 months of treatment from two hospitals.
