As the COVID-19 pandemic surged, lockdowns led to the cancellation of essential health services. As part of our Zero TB activities in Karachi, we adapted our approach to integrate activities for TB and COVID-19 to decrease the impact on diagnosis and linkage to care for TB treatment. We implemented the following: (1) integrated COVID-19 screening and testing within existing TB program activities, along with the use of an artificial intelligence (AI) software reader on digital chest X-rays; (2) home delivery of medication; (3) use of telehealth and mental health counseling; (4) provision of PPE; (5) burnout monitoring of health workers; and (6) patient safety and disinfectant protocol. We used programmatic data for six districts of Karachi from January 2018 to March 2021 to explore the time trends in case notifications, the impact of the COVID-19 pandemic, and service adaptations in the city. The case notifications in all six districts in Karachi were over 80% of the trend-adjusted expected notifications with three districts having over 90% of the expected case notifications. Overall, Karachi reached 90% of the expected case notifications during the COVID-19 pandemic. The collaborative efforts by the provincial TB program and private sector partners facilitated this reduced loss in case notifications.

Abstract Background Tuberculosis case-finding interventions often involve several activities to enhance patient pathways, and it is unclear which activity defines the type of case-finding intervention. When conducting studies to identify the most effective case-finding intervention it is important to have a clear understanding of these interventions for meaningful comparisons. This review aimed to construct a systems-based logic model of all pathways to tuberculosis case detection through a synthesis of intervention designs. Methods We identified an existing systematic review on the effectiveness of interventions to increase tuberculosis case detection and updated the search from December 2016 to October 2020. We included randomized controlled trials, as these designs encourage detailed description of interventions. Taking each study in turn, intervention descriptions were read in detail. The texts were analysed qualitatively by constantly comparing emerging codes to construct patient journeys, visualized as logical chains. Actions taken as part of interventions were positioned along patient journeys to theorize the sequence of outcomes. Patient journeys formed the basis of the model, which was refined through discussion. Results Based on intervention descriptions from 17 randomized controlled trials, our model distinguishes two care-seeking pathways and four screening pathways. An open invitation to people with tuberculosis symptoms creates care-seeking pathways. On care-seeking pathways, systematic screening can be conducted at general health services, but not at specific TB care services. People invited to tuberculosis services regardless of symptoms follow tuberculosis screening pathways and may be identified with presumptive tuberculosis even if they do not seek care for tuberculosis symptoms. Tuberculosis screening pathways include screening offered to all people accessing care at general health services, screening at a mobile clinic or health facility with open invitation to a whole population or tuberculosis contacts, screening personally offered to a whole population or tuberculosis contacts at home, work or school, and screening offered to people receiving care for human immunodeficiency virus or other clinical risk-group care. Conclusion This systems-based logic model of tuberculosis case-finding pathways may support standardized terminology, consistency, transparency and improved communication among researchers, policy-makers, health workers and community members when implementing and evaluating interventions to improve tuberculosis case detection.

Tuberculosis is an infectious disease that can infect one person to another caused by the bacterium Mycobacterium tuberculosis. This disease is not only transmitted to people of productive age (15-45), but teenagers or children under 15 years can also be infected with the bacteria. Every year new cases are found in Indonesia, such as in the work area of the Paninggaran Health Center, Paninggaran District. Public Health Centers and Hospitals are health facilities for the community that have the facilities and infrastructure to determine how large the coverage of health figures for the community is. From this analysis, it can be found the obstacles that must be faced, namely how to provide information to the public about the spread of Tuberculosis in Paninggaran District. This is what underlies this research to create an Android-based Geographic Information System application for the distribution of tuberculosis in Paninggaran District with menus that are useful for the wider community and easy to use. The method used in this research is the Waterfall Method. The final result of this study is a "Geographical Information System for the Distribution of Tuberculosis in Paninggaran District" in the form of an android application for the community and a website for admins, namely Paninggaran Health Center officers, so that it can facilitate the distribution of information about Tuberculosis to the community and related health services, this application can also displays a map of the distribution of Tuberculosis disease, the location of where Tuberculosis patients live, the number of Tuberculosis case data and educational news about Tuberculosis disease.

Background Tuberculosis (TB) and COVID-19 pandemics are both diseases of public health threat globally. Both diseases are caused by pathogens that infect mainly the respiratory system, and are involved in airborne transmission; they also share some clinical signs and symptoms. We, therefore, took advantage of collected sputum samples at the early stage of COVID-19 outbreak in Ghana to conduct differential diagnoses of long-standing endemic respiratory illness, particularly tuberculosis. Methodology Sputum samples collected through the enhanced national surveys from suspected COVID-19 patients and contact tracing cases were analyzed for TB. The sputum samples were processed using Cepheid’s GeneXpert MTB/RIF assay in pools of 4 samples to determine the presence of Mycobacterium tuberculosis complex. Positive pools were then decoupled and analyzed individually. Details of positive TB samples were forwarded to the NTP for appropriate case management. Results Seven-hundred and seventy-four sputum samples were analyzed for Mycobacterium tuberculosis in both suspected COVID-19 cases (679/774, 87.7%) and their contacts (95/774, 12.3%). A total of 111 (14.3%) were diagnosed with SARS CoV-2 infection and six (0.8%) out of the 774 individuals tested positive for pulmonary tuberculosis: five (83.3%) males and one female (16.7%). Drug susceptibility analysis identified 1 (16.7%) rifampicin-resistant tuberculosis case. Out of the six TB positive cases, 2 (33.3%) tested positive for COVID-19 indicating a coinfection. Stratifying by demography, three out of the six (50%) were from the Ayawaso West District. All positive cases received appropriate treatment at the respective sub-district according to the national guidelines. Conclusion Our findings highlight the need for differential diagnosis among COVID-19 suspected cases and regular active TB surveillance in TB endemic settings.

Aim: To demonstrate the need for routine active TB case finding in Nigerian correctional centers through a TB case surveillance intervention at the largest correctional centre in the most populous state in Nigeria by KNCV Tuberculosis Foundation Nigeria. Study Design: It was a retrospective review of public health intervention data derived from the mass TB screening of Kano central correctional centre inmates in Kano state, Nigeria. Methodology: A digital X-ray with artificial intelligence (AI) was used for mass TB screening of 1,967 consenting inmates at the Kano central correctional centre in Kano state, Nigeria, from 21st September to 2nd October 2020. Participants with CAD4TB score ≥ 60 had a GeneXpert assessment of their sputa for TB diagnosis. Where sputum production was not possible, or GeneXpert result was negative, expert clinical evaluation of the presumptive radiogram was carried out by experienced radiologist. Data from the project were extracted and analysed for this report. Proportions and means were compared with Fisher Exact test and Student t-test, respectively. A p-value of < 0.05 was considered statistically significant. Results: Overall, 1,967 inmates were screened for TB and 92 (4.7%) presumptive were identified - males (4.8%, 91/92), females (1.9%, 1/92). Out of the 92 presumptive, 21 males were diagnosed as TB cases giving a TB prevalence of 1.1% among the inmates and 22.8% among presumptive. One of the TB cases had multi-drug resistant TB. The number needed to screen (NNS) was 94. All TB cases were enrolled in treatment. Conclusion: The prevalence of TB at the Kano central correctional centre during the mass TB screening project was high. The National Tuberculosis Control Programme of Nigeria should accelerate the planned paradigm shift from passive to active case-finding for TB in Nigerian correctional centers.

Abstract Background Tuberculosis continues to be a worldwide public health problem. Despite the noted gradual decline in tuberculosis case rates in the UK, clinicians should still be aware of these unusual presentations. Sternal tuberculosis is an uncommon form of extrapulmonary tuberculosis and it can initially be a diagnostic challenge for paediatricians. These lesions can present with nonspecific signs and symptoms that may mimic malignancy. Case presentation We present a case of a 3-year-old African descent girl with a sternal swelling that was confirmed to be Mycobacterium tuberculosis complex DNA on gastric aspirate. The child had additional radiological investigations that corresponded accordingly. She was started on quadruple antituberculosis therapy with good outcome. Conclusion Tuberculosis sternal abscess is as rare finding, especially in developed countries where tuberculosis is not endemic. Tuberculosis may not always present with pulmonary symptoms in children. There should be a high suspicion of tuberculosis, especially in immigrant population presenting with unusual presentations. Our aim is to increase awareness around atypical presentations of tuberculosis in children. Although, tuberculosis is endemic to underdeveloped countries, clinicians should still be aware of presentations in view of current global migration.

Introdução: A doença de Crohn é uma doença inflamatória intestinal (DII) que inicia um processo inflamatório crônico idiopático intestinal, levando a um quadro clínico variávelcujo principal sintoma é a diarreia crônica. O diagnóstico é feito a partir da combinação de dados clínicos, laboratoriais e exames endoscópicos. Após confirmado o diagnóstico, otratamento pode envolver classes medicamentosas como imunobiológicos. Em relação ao uso de imunobiológicos, como o adalimumabe, deve-se ter cautela pelo seu efeitoimunossupressor, que pode, em indivíduos susceptíveis, ativar focos latentes de infecção, como os de tuberculose (TB). Objetivo: Relatar um caso de tuberculose miliar como reação adversa ao uso de adalimumabe e conscientizar a comunidade médica quanto aos riscos da administração de terapia imunobiológica. Relato de caso: Paciente do sexo masculino, 31 anos, com diagnóstico de Doença de Crohn em acompanhamento ambulatorial com terapia imunobiológica com adalimumab, é admitido na emergência com quadro agudo de sintomas respiratórios e sistêmicos. Durante a investigação hospitalar, apesar de pesquisa do bacilo álcool- -ácido resistente (BAAR) no escarro ter apresentado três amostras negativas, a tomografia computadorizada (TC) de tórax apresentava padrão sugestivo de tuberculose miliar, além de um lavado broncoalveolar com pesquisa positiva para Mycobacterium tuberculosis. Confirmado o diagnóstico de TB miliar, o tratamento foi iniciado com  rifampicina, isoniazida, pirazinamida e etambutol. Conclusão: Levando em consideração a alta mortalidade e os impactos negativos da tuberculose miliar, é imprescindível que todos os pacientes com DII em uso de imunobiológicos sejam rastreados para infecção latente, através da radiografia de tórax e teste tuberculínico (PPD). Entretanto, mesmo com o rastreio regular e registro de vacinação prévia, a possibilidade de tuberculose miliar ainda não pode ser descartada em quadros clínicos inespecíficos neste perfil de pacientes.Palavras chave: Adalimumab, Tuberculose, Efeitos colaterais e reações adversas relacionados a medicamentosABSTRACTIntroduction: Crohn’s disease is an inflammatory bowel disease (IBD) that initiates a chronic idiopathic intestinal inflammatory process, leading to a variety of clinical symptoms with chronic diarrhea as the main one. Diagnosis is built from a combination of clinical, laboratory and endoscopic data. The treatment involves immunobiological drugs, such as adalimumab and due to its immunosuppressive effect, it must be administered with caution, because it isable to activate latent foci of infection, such as tuberculosis (TB), in susceptible individuals. Objective: To report a miliary tuberculosis case originated as an adverse reaction to the use of adalimumab and to make the medical community aware of the risks of administering immunobiological therapy. Case report: A 31-year-old male, diagnosed with Crohn’s Disease, undergoing immunobiological treatment with adalimumab, is admitted in the emergency department with acute respiratory and systemic symptoms. During hospitalization, despite the investigation of alcohol-acid resistant bacillus (BAAR) in sputum showing three different samples with negative results, the computerized tomography (CT) of the chest showed a pattern suggestive of miliary tuberculosis, in addition to a bronchoalveolar lavage with a positive test for Mycobacterium tuberculosis. After the diagnosis of miliary TB was confirmed, treatment with rifampicin, isoniazid, pyrazinamide and ethambutol was started. Conclusion: Considering the high mortality and negative impacts of miliary tuberculosis, it is essentialthat all patients with IBD on immunobiological treatment are screened for latent infection through chest radiograph and PPD. However, even with regular screening and registration of previous vaccinations, the possibility of miliary tuberculosis cannot be ruled out in this profile of patients with unspecific clinical conditions.Keywords: Adalimumab, Tuberculosis, Drug-related side effects and adverse reactions

Background: Globally, tuberculosis remains a major cause of mortality, with an estimated 1.3 million deaths per annum. The Xpert MTB/RIF assay is used as the initial diagnostic test in the tuberculosis diagnostic algorithm. To extend the national tuberculosis testing programme in South Africa, mobile units fitted with the GeneXpert equipment were introduced to high-burden peri-mining communities.Objective: This study sought to assess the cost of mobile testing compared to traditional laboratory-based testing in a peri-mining community setting.Methods: Actual cost data for mobile and laboratory-based Xpert MTB/RIF testing from 2018 were analysed using a bottom-up ingredients-based approach to establish the annual equivalent cost and the cost per result. Historical cost data were obtained from supplier quotations and the local enterprise resource planning system. Costs were obtained in rand and reported in United States dollars (USD).Results: The mobile units performed 4866 tests with an overall cost per result of $49.16. Staffing accounted for 30.7% of this cost, while reagents and laboratory equipment accounted for 20.7% and 20.8%. The cost per result of traditional laboratory-based testing was $15.44 US dollars (USD). The cost for identifying a tuberculosis-positive result using mobile testing was $439.58 USD per case, compared to $164.95 USD with laboratory-based testing.Conclusion: Mobile testing is substantially more expensive than traditional laboratory services but offers benefits for rapid tuberculosis case detection and same-day antiretroviral therapy initiation. Mobile tuberculosis testing should however be reserved for high-burden communities with limited access to laboratory testing where immediate intervention can benefit patient outcomes.

The objective: to study the degree of specific sensitization according to the results of intradermal immunodiagnostic tests in children with different manifestations of tuberculosis infection under the current epidemic situation.Subjects and Methods. The degree of tuberculin sensitization was studied in 299 children from different age groups (0-14 years old) who were registered for dispensary follow-up in 2018-2019.Based on the results of a tuberculosis recombinant allergen test (TRA), the degree of specific sensitization was studied in children with tuberculin tests conversion (n = 102) and infected with Mycobacterium tuberculosis (MTB) for 2 years or more (n = 165) exposed to tuberculous infection in their families and from healthy environment, and 145 patients under 14 years old with local respiratory tuberculosis.Results. Moderate sensitization to tuberculin predominated in children with converted tuberculin test exposed to tuberculous infection in their families and those from healthy environments. According to the results of TRA test, a high degree of sensitization was observed 4.7 times more frequently in children with tuberculin test conversion exposed to tuberculosis in their families. In children from healthy environments, negative responses to TRA test were registered 2.4 times more frequently. In 73% of children infected with MTB, results of annual Mantoux tests didn’t differ much. Hyperergic reactions to TRA test in infected children exposed to tuberculous infection were 10 times more frequent than in those from healthy environments. A direct correlation was found between the high degree of sensitization to active M. tuberculosis and exposure to a tuberculosis case with a positive result of sputum test (χ2 < 0.001, p < 0.05). In the case of converted tuberculin test and infection with M. tuberculosis for 2 years or more, pronounced and hyperergic reactions to TRA test were registered with equal frequency and did not depend on the timing and duration of infection. A high risk factor and predictor of the disease development is high sensitization of the host to active M. tuberculosis which is found in patients with tuberculosis using TRA test six times more frequently versus Mantoux test (OR 5.951, 95% CI 3.548 and 9.981). The demonstrated results are important for the identification of children facing a high risk to develop active tuberculosis and preventive treatment prescription.
