Background Tuberculosis (TB) remains a major public health threat in Ghana. The impact of COVID-19 resulted in a 15% decline of TB case notification in 2020 compared to 2019. To mitigate the impact on TB services, the Ghana National Tuberculosis Programme (NTP) introduced the bidirectional screening and testing for TB and COVID-19 in 2021. Objective To evaluate the yield of bidirectional screening and testing for TB and COVID-19 among facility attendees in the Greater Accra region. Method We used secondary data obtained from the initial implementation stage of the bidirectional testing for TB and COVID-19 among COVID-19 and/or TB presumed cases in five health facilities in the Greater Accra Region from January to March 2021. To mitigate the impact of COVID-19 on TB services and accelerate TB case detection, the NTP of Ghana introduced bidirectional screening and testing for TB and COVID-19 in Greater Accra Region before scaling up at national level. Results A total of 208 presumed TB or COVID-19 cases were identified: 113 were tested for COVID-19 only, and 94 were tested for both TB and COVID-19, 1 was tested for TB only. Among presumed cases tested for COVID-19, 9.7% (95% CI, 5.6-13.7%) were tested positive. Whilst among the total presumed tested for TB, 13.7% (95% CI, 6.8-20.6%) were confirmed to have TB. Among the total 94 presumed cases tested for both TB and COVID-19, 11.7% (95% CI, 5.2-18.2%) were confirmed to have TB and 13.8% (95% CI, 6.9-20.8%) participants were COVID-19 positive and one participant (1.1%) had both COVID-19 and TB. Conclusion Bidirectional screening and testing for TB and COVID-19 shows significant potential for improving overall case detection for the two diseases. The bidirectional screening and testing could be applicable to address a similar respiratory epidemic in the future that might have a masking effect on the response to TB disease.

Background In many low and middle-income countries, Tuberculosis (TB) surveillance systems miss out on reporting on detected cases suggesting gaps in the TB case detection and documentation systems. The World Health Organisation estimates that less than half of TB cases in Ghana are notified. Capture-recapture (CR) techniques that involve data linkages have been applied in various settings to estimate the total number of tuberculosis cases, including those unreported. This study evaluated the completeness of reporting of TB in a region of Ghana using CR techniques. Methods We evaluated the completeness of TB case notification data reported between 2016 and 2017 by performing record linkage in five out of 26 districts in the Eastern Region of Ghana. We linked data of all bacteriologically confirmed pulmonary TB (PTB) cases recorded in three registries, namely the district, laboratory, and treatment centre registers, to identify gaps in notification. Regression analysis was used to assess linkages of the three records based on name, age and sex. We estimated overall completeness with log-linear modelling. Results There were 2,035 cases across the three registers, of which 773 (38%) were bacteriologically confirmed. The district, laboratory and treatment centre registers had recorded 369 (47.7%), 368 (47.6%) and 404 (52.3%) of the confirmed cases respectively. Only 82 (10.6%) cases were consistent across all three registers. There were 115 (14.9%), 238 (30.8%) and 134 (17.3%) cases that were exclusively in the district, laboratory and treatment centre registers. Log-linear capture-recapture model estimated 2,483 (95%CI: 1,797; 3,813) as expected number of confirmed cases. On that basis, overall completeness of reporting of the district TB registry was 14.9% (369/2,483; 95%CI: 13.5, 16.3). Conclusion We found low levels of completeness of TB case reporting in the study area. A more wider assessment of the surveillance system in Ghana is needed to identify gaps in reporting.

Introduction Tuberculosis (TB) remains a major cause of morbidity and mortality, especially in sub-Saharan Africa. We qualitatively evaluated the implementation of an Evidence-Based Multiple Focus Integrated Intensified TB Screening package (EXIT-TB) in the East African region, aimed at increasing TB case detection and number of patients receiving care. Objective We present the accounts of participants from Tanzania, Kenya, Uganda, and Ethiopia regarding the implementation of EXIT-TB, and suggestions for scaling up. Methods A qualitative descriptive design was used to gather insights from purposefully selected healthcare workers, community health workers, and other stakeholders. A total of 27, 13, 14, and 19 in-depth interviews were conducted in Tanzania, Kenya, Uganda, and Ethiopia respectively. Data were transcribed and translated simultaneously and then thematically analysed. Results The EXIT-TB project was described to contribute to increased TB case detection, improved detection of Multidrug-resistant TB patients, reduced delays and waiting time for diagnosis, raised the index of TB suspicion, and improved decision-making among HCWs. The attributes of TB case detection were: (i) free X-ray screening services; (ii) integrating TB case-finding activities in other clinics such as Reproductive and Child Health clinics (RCH), and diabetic clinics; (iii), engagement of CHWs, policymakers, and ministry level program managers; (iv) enhanced community awareness and linkage of clients; (v) cooperation between HCWs and CHWs, (vi) improved screening infrastructure, (vii) the adoption of the new simplified screening criteria and (viii) training of implementers. The supply-side challenges encountered ranged from disorganized care, limited space, the COVID-19 pandemic, inadequate human resources, inadequate knowledge and expertise, stock out of supplies, delayed maintenance of equipment, to absence of X-ray and GeneXpert machines in some facilities. The demand side challenges ranged from delayed care seeking, inadequate awareness, negative beliefs, fears towards screening, to financial challenges. Suggestions for scaling up ranged from improving service delivery, access to diagnostic equipment and supplies, and infrastructure, to addressing client fears and stigma. Conclusion The EXIT-TB package appears to have contributed towards increasing TB case detection and reducing delays in TB treatment in the study settings. Addressing the challenges identified is needed to maximize the impact of the EXIT-TB intervention.

Background Liberia is among the three west African countries which were crippled by the Ebola Virus Disease (EVD) outbreak of 2014. One of the programs which was affected by the EVD outbreak was the National Leprosy and Tuberculosis Control Program (NLTCP). Determining the magnitude of the impact of EVD on the NLTCP performance is crucial in restoring the service and in devising effective post EVD strategies. The purpose of the study was to analyse the impact of EVD outbreak on the performance of the NLTCP of the Ministry of Health (MOH) OF Liberia. Methods A cross sectional study design was conducted in 2016 using both quantitative and qualitative methods. Quantitative data was used for the Tuberculosis (TB) program evaluation before EVD (2012–2013) and during EVD (2014–2015). Qualitative data was used to complement the data obtained for the quantitative study. Descriptive statistical analyses of quantitative data were conducted using Microsoft Excel. Results Notified TB cases of all forms decreased from 7822 in 2013 to 4763 and 6118 in 2014 and 2015 respectively. The number increased to 7180 and 7728 in 2016 and 2017 respectively. The TB treatment success rate was 71 and 61% in 2014 and 2015 respectively compared to the 83% in 2013. The treatment success rate was 77% in 2016. The loss to follow up (LTFU) was as high as 47% in some regions which were highly affected by the EVD outbreak. The national average LTFU was 5–10% in 2012–2013 and 16 and 21% in 2014 and 2015 respectively. The percentage of TB patients with known HIV result decreased from 75% in 2013 to 74 and 42% in 2014 and 2015 respectively. TB culture and drug susceptibility testing service was interrupted throughout the outbreak. The results of the focal group discussions and interviews conducted in our study also indicated that the TB case finding and the TB treatment outcome was significantly affected by the EVD outbreak. Conclusion Notified TB cases and treatment outcome was significantly affected by the EVD outbreak which occurred in 2014 and 2015 in Liberia. Effective restoration strategies should be developed in order to improve the TB case finding and treatment outcome.

Background Ethiopia has highly diversified population with notable socioeconomic and cultural differences. Regardless of the differences, short course directly observed treatment,where patients should take drugs under direct observasion of health care providers, is uniformly applied all over the country. Evidences are scarce on how well does this uniform approach fits with the pastoral community setting. The purpose of this study was to explore lived experiences of TB patients in the pastoral community under the uniform approach, and their implications to early case identification and management. Method Qualitative method with phenomenological study design was undertaken to explore lived experiences of TB patients. Patients from all levels of health care (hospital, health center and health post) were included. Experience of both drug susceptible and drug resistant TB patients were documented. Twenty one patients, who consented to in the study, were selected by a convenience sampling method. In-depth interview was conducted using a semi-structured interview guide and the interview ended subsequent to information saturation. The interview was audio recorded; and field notes were also taken. Data analysis was done concurrently with the data collection using a word processor designed for qualitative text analysis. InductiveThematic analysis was undertaken to identify key themes. Results Twenty one patients (eight from hospitals, nine from health centers and four from health posts) were interviewed. Three of the eight hospital patients were on drug resistant tuberculosis (TB) treatment. Sixty two codes, five code categories and three themes emerged from the interviews. The three themes were health system, stigma and discrimination, and socioeconomic problem related experiences. Inaccessibility to health facilities due to scattered settlement and mobility, delay in care seeking TB symptoms, low index of suspecting TB by care providers, fear of stigma and indirect treatment related costs were some of the codes identified. Conclusion TB patients in the pastoral setting were experiencing multifaceted challenges with the current application of ‘ one-size-fits-all’ approach which implied hampered timely case identification and compromised patient management. Therefore, designing context appropriate intervention approach is required to ensure unprejudiced services.

Background: Pediatric osteoarticular tuberculosis (TB) remains a significant global health challenge, particularly in resource-limited settings, where delayed diagnosis and treatment frequently lead to severe long-term complications. Despite advancements in TB control, skeletal TB in children is often misdiagnosed due to its non-specific clinical presentation, contributing to poor outcomes such as joint deformities, growth disturbances, and chronic pain. The complexity of diagnosing osteoarticular TB is further exacerbated by the limited sensitivity of conventional diagnostic tools and the overlap with other musculoskeletal conditions. This study seeks to evaluate the impact of early detection and multidisciplinary management on treatment outcomes in pediatric patients with osteoarticular TB. Methods: A retrospective review was conducted at the Pediatric Orthopedics Department of the “Grigore Alexandrescu” Children’s Hospital in Romania from 2009 to 2023. Case data included clinical, imaging, and microbiological findings, and treatment outcomes in children aged 0–18 years diagnosed with tuberculous osteomyelitis. Results: The study identified varied clinical presentations, with delayed diagnosis often linked to misinterpretation of symptoms as non-TB infections. Multimodal diagnostic approaches combining imaging, microbiological testing, and histopathology improved diagnostic accuracy. Early surgical intervention alongside anti-TB therapy proved effective in reducing long-term complications. Conclusions: Timely, accurate diagnosis and multidisciplinary treatment are critical to improving outcomes in pediatric osteoarticular TB. Vaccination status and comprehensive diagnostic tools significantly influence disease progression and treatment success. The study underscores the need for enhanced screening and diagnostic methods to prevent delays in treatment.

Finding individuals with drug-resistant tuberculosis (DR-TB) is important to control the pandemic and improve patient clinical outcomes. To our knowledge, systematic reviews assessing the effectiveness, cost-effectiveness, acceptability, and feasibility of different DR-TB case-finding strategies to inform research, policy, and practice, have not been conducted and the scope of primary research is unknown. We therefore assessed the available literature on DR-TB case-finding strategies. We looked at systematic reviews, trials, qualitative studies, diagnostic test accuracy studies, and other primary research that sought to improve DR-TB case detection specifically. We excluded studies that included patients seeking care for tuberculosis (TB) symptoms, patients already diagnosed with TB, or were laboratory-based. We searched the academic databases of MEDLINE, Embase, The Cochrane Library, Africa-Wide Information, CINAHL (Cumulated Index to Nursing and Allied Health Literature), Epistemonikos, and PROSPERO (The International Prospective Register of Systematic Reviews) using no language or date restrictions. We screened titles, abstracts, and full-text articles in duplicate. Data extraction and analyses were carried out in Excel (Microsoft Corp). We screened 3646 titles and abstracts and 236 full-text articles. We identified 6 systematic reviews and 61 primary studies. Five reviews described the yield of contact investigation and focused on household contacts, airline contacts, comparison between drug-susceptible tuberculosis and DR-TB contacts, and concordance of DR-TB profiles between index cases and contacts. One review compared universal versus selective drug resistance testing. Primary studies described (1) 34 contact investigations, (2) 17 outbreak investigations, (3) 3 airline contact investigations, (4) 5 epidemiological analyses, (5) 1 public-private partnership program, and (6) an e-registry program. Primary studies were all descriptive and included cross-sectional and retrospective reviews of program data. No trials were identified. Data extraction from contact investigations was difficult due to incomplete reporting of relevant information. Existing descriptive reviews can be updated, but there is a dearth of knowledge on the effectiveness, cost-effectiveness, acceptability, and feasibility of DR-TB case-finding strategies to inform policy and practice. There is also a need for standardization of terminology, design, and reporting of DR-TB case-finding studies.

Abstract We report 2 cases for whom Xpert MTB/RIF falsely signaled rifampicin-resistant tuberculosis, based on unusually low cycle threshold and 3 of 5 probes missing. Other mycobacterial tests were negative. Further optimization of the Xpert MTB/RIF algorithm is warranted.

In this study, copper, zinc, magnesium, manganese, selenium, and iron of urine and hair were measured in the patients with tuberculous (TB) pleurisy (n = 24) and in the control group (n = 20). Selenium, magnesium, and zinc of hair were found to be significantly lower in TB pleurisy cases than those in the control group (p < 0.05, p < 0.001, and p < 0.01, respectively). On the contrary, selenium and magnesium of urine were found to be significantly elevated in TB pleurisy cases than those in the control group (p < 0.05 and p < 0.001, respectively). There was no significant difference in the value of manganese and iron between TB pleurisy and the control group (p > 0.05). Copper level were significantly increased in hair and decreased in urine of the patients (p < 0.01). The occurrence of these abnormalities constitutes new information regarding trace elements in TB pleurisy patients. These results may provide an additional disease correlate for assessing TB pleurisy risk.

Case detection of an infectious individual and differentiation of infectiveness of a treated patient during two different stages of treatment are recognized as among key factors for the successful control and management of tuberculosis (TB) transmission. In this paper, a dynamic compartmental model is developed that incorporates these factors, and proofs are provided to show that the model's global dynamics are completely characterized by the control reproduction number, and in particular the disease eradication condition in terms of the case detection fraction is obtained, along with some numerical simulations.
