Progress and challenges in achieving tuberculosis elimination in India by 2025: A systematic review and meta-analysis.

BACKGROUND: Tuberculosis (TB) continues to pose a significant public health challenge in India, which is home to one of the highest TB burdens worldwide. This systematic review and meta-analysis will aim to synthesize the anticipated progress and potential challenges in achieving TB elimination in India by 2025. METHODS: A comprehensive search will be conducted across multiple databases, including PubMed, Scopus, and Web of Science, to identify relevant studies. The eligibility criteria will encompass individuals diagnosed with TB in India, interventions targeting TB treatment, prevention, or control, and various comparator groups. Outcomes of interest will include incidence reduction, mortality rate, treatment success rate, barriers to TB care, and more. Both quantitative and qualitative data will be synthesized, and the risk of bias will be assessed using established tools. OUTCOMES: The review is expected to provide a holistic understanding of the TB landscape in India, highlighting the effective interventions and potential challenges in the journey towards TB elimination. CONCLUSIONS: While it is anticipated that significant progress will be made in the fight against TB in India, challenges are likely to persist. This review will offer a comprehensive roadmap for researchers, policymakers, and healthcare professionals, emphasizing the importance of continued efforts, innovative strategies, and a multi-pronged approach in achieving the goal of TB elimination in India by 2025.

Phosphatidylinositolmannoside vaccination induces lipid-specific Th1-responses and partially protects guinea pigs from Mycobacterium tuberculosis challenge.

The concept of donor-unrestricted T cells (DURTs) comprises a heterogeneity of lymphoid cells that respond to an abundance of unconventional epitopes in a non-MHC-restricted manner. Vaccinologists strive to harness this so far underexplored branch of the immune system for new vaccines against tuberculosis. A particular division of DURTs are T cells that recognize their cognate lipid antigen in the context of CD1-molecules. Mycobacteria are characterized by a particular lipid-rich cell wall. Several of these lipids have been shown to be presented to T cells via CD1b-molecules. Guinea pigs functionally express CD1b and are hence an appropriate small animal model to study the role of CD1b-restricted, lipid-specific immune responses. In the current study, guinea pigs were vaccinated with BCG or highly-purified, liposome-formulated phosphatidylinositol-hexa-mannoside (PIM6) to assess the effect of CD1-restricted DURTs on the course of infection after virulent Mycobacterium tuberculosis (Mtb) challenge. Robust PIM6-specific T cell-responses were observed both after BCG- and PIM6-vaccination. The cellular response was significantly reduced in the presence of monoclonal, CD1b-blocking antibodies, indicating that a predominant part of this reactivity was CD1b-restricted. When animals were challenged with Mtb, BCG- and PIM6-vaccinated animals showed significantly reduced pathology, smaller necrotic granulomas in lymph node and spleen and reduced bacterial loads. While BCG conferred an almost sterile protection in this setting, compared to control animals' lesions were reduced roughly by two thirds in PIM6-vaccinated. Comprehensive histological and transcriptional analyses in the draining lymph node revealed that protected animals showed reduced transcription-levels of inflammatory cyto- and chemokines and higher levels of CD1b-expression on professional antigen cells compared to controls. Although BCG as a comparator induced by far stronger effects, our observations in the guinea pig model suggest that CD1b-restricted, PIM6-reactive DURTs contribute to immune-mediated containment of virulent Mtb.

Holistic Approach to Enhance Airborne Infection Control Practices in Health Care Facilities Involved in the Management of Tuberculosis in a Metropolitan City in India - An Implementation Research.

Background: Airborne infection control (AIC) is a less focused aspect of tuberculosis (TB) prevention. We describe AIC practices in primary health care centres, awareness and practices of AIC among health care providers (HCPs) and TB patients. We implemented a package of interventions to improve awareness and practices among them and assessed its impact. Methodology: The study used a quasi-experimental study design. A semi-structured checklist was used for health facility assessment and a self-administered questionnaire of HCPs. Pre- and postintervention assessments were made in urban primary health centers (UPHCs), HCPs, and patients. Interventions included sharing facility-specific recommendations, AIC plans and guidelines, HCP training, and patient education. Statistical difference between the two time periods was assessed using the Chi-square test. Results: A total of 23 and 25 UPHCs were included for pre- and postintervention assessments. All 25 centers participated in interventions. Open areas were >20% of ground area in all facilities. No AIC committee was present in any of the facilities at both pre- and postintervention. Of all HCPs, 7% (23/337) versus 65% (202/310) had undergone AIC training. Good awareness improved from 24% (81/337) to 71% (220/310) after intervention (P < 0.001). Appropriate cough hygiene was known to 20% (51/262) versus 58% (152/263) patients at two assessments (P < 0.001). Conclusion: Comprehensive intervention, including supportive supervision of health centers, training of HCPs, and patient education, can improve AIC practices.

Vitamin D supplementation to prevent tuberculosis infection in South African schoolchildren: multicenter phase 3 double-blind randomized placebo-controlled trial (ViDiKids).

OBJECTIVES: To determine whether weekly oral supplementation with 10,000 IU vitamin D3 for 3 years reduces the risk of sensitization to M. tuberculosis in South African schoolchildren aged 6-11 years with negative QuantiFERON-tuberculosis (TB) Gold Plus (QFT-Plus) assay results at baseline. METHODS: We conducted a phase 3 randomized placebo-controlled trial in 1682 children attending 23 primary schools in Cape Town. The primary outcome was a positive end-trial QFT-Plus result, analyzed using a mixed effects logistic regression model with the school of attendance included as a random effect. RESULTS: 829 vs. 853 QFT-Plus-negative children were randomized to receive vitamin D3 vs. placebo, respectively. Mean end-study 25(OH)D concentrations in participants randomized to vitamin D vs. placebo were 104.3 vs 64.7 nmol/l, respectively (95% confidence interval for difference, 37.6 to 41.9 nmol/l). A total of 76/667 (11.4%) participants allocated to vitamin D vs. 89/687 (13.0%) participants allocated to placebo tested QFT-Plus positive at 3-year follow-up (adjusted odds ratio 0.86, 95% confidence interval 0.62-1.19, P = 0.35). CONCLUSION: Weekly oral supplementation with 10,000 IU vitamin D3 for 3 years elevated serum 25(OH)D concentrations among QFT-Plus-negative Cape Town schoolchildren but did not reduce their risk of QFT-Plus conversion.

--Eleven tips for operational researchers working with health programmes: our experience based on implementing differentiated tuberculosis care in south India.

Due to the workload and lack of a critical mass of trained operational researchers within their ranks, health systems and programmes may not be able to dedicate sufficient time to conducting operational research (OR). Hence, they may need the technical support of operational researchers from research/academic organisations. Additionally, there is a knowledge gap regarding implementing differentiated tuberculosis (TB) care in programme settings. In this 'how we did it' paper, we share our experience of implementing a differentiated TB care model along with an inbuilt OR component in Tamil Nadu, a southern state in India. This was a health system initiative through a collaboration of the State TB cell with the Indian Council of Medical Research institutes and the World Health Organisation country office in India. The learnings are in the form of eleven tips: four broad principles (OR on priority areas and make it a health system initiative, implement simple and holistic ideas, embed OR within routine programme settings, aim for long-term engagement), four related to strategic planning (big team of investigators, joint leadership, decentralised decision-making, working in advance) and three about implementation planning (conducting pilots, smart use of e-tools and operational research publications at frequent intervals). These may act as a guide for other Indian states, high TB burden countries that want to implement differentiated care, and for operational researchers in providing technical assistance for strengthening implementation and conducting OR in health systems and programmes (TB or other health programmes). Following these tips may increase the chances of i) an enriching engagement, ii) policy/practice change, and iii) sustainable implementation.

Levantamento epidemiológico dos casos de tuberculose no Brasil e ações alternativas para auxiliar no tratamento / Epidemiological survey of tuberculosis cases in Brazil and alternative actions to aid in treatment / Estudio epidemiológico de los casos de tuberculosis en Brasil y acciones alternativas para ayudar al tratamiento

tuberculose é uma das doenças infectocontagiosas de maior importância no Brasil e no mundo. Afeta de forma importante populações em situação de vulnerabilidade social e econômica. O objetivo deste estudo foi realizar um levantamento do número de casos notificados de tuberculose no Brasil nos últimos 10 anos (2011 a 2021), avaliar os fatores que afetam a transmissão, bem como discutir o tratamento padrão e com fitoterápicos. O levantamento epidemiológico dos casos de tuberculose no Brasil de janeiro de 2011 a dezembro de 2021 foi realizado dentre os notificados pelo Sistema de Informação de Agravos de Notificação (SINAN). Os resultados indicaram um aumento linear de casos a partir de 2017 com 90.776 casos diagnosticados, em 2018 (94.720) e 2019 (96.655). Acredita-se que o aumento linear da tuberculose neste período pode estar relacionado principalmente com o aumento da pobreza, contudo o compartilhamento de utensílios durante o uso de narguilé podem representar fatores de risco para tuberculose. Seis plantas medicinais afetam diretamente as micobactérias (Chenopodium ambrosioides, Tetradenia riparia, Physalis angulata, Origanum vulgare, Eucalyptus globulus, Mikania glomerata) e cinco plantas com atividade antibacteriana auxiliam no trato respiratório (Nasturtium officinale, Allium sativum, Schinus terebinthifolius, Adiantum capillus-veneris, Allium cepa). Contudo, a tuberculose é uma doença reemergente sendo necessária a adoção de políticas públicas que intensifiquem e implementem medidas sócio-educativas para a implantação do uso de fitoterápicos como medida complementar.

Tuberculosis is one of the most important infectious diseases in Brazil and worldwide. It significantly affects populations in situations of social and economic vulnerability. This study aimed to survey the number of reported tuberculosis cases in Brazil in the last 10 years (2011 to 2021) to assess the factors that affect the transmission and discuss standard and herbal treatments. The epidemiological survey of tuberculosis cases in Brazil from January 2011 to December 2021 was carried out among those notified by the Notifiable Diseases Information System (SINAN). The results indicated a linear increase in cases from 2017, with 90,776 diagnosed cases, in 2018 (94,720) and 2019 (96,655). It is believed that the linear increase in tuberculosis in this period may be mainly related to the increase in poverty. However, the sharing of utensils during the use of hookah may represent risk factors for tuberculosis. Six medicinal plants directly affect mycobacteria (Chenopodium ambrosioides, Tetradenia riparia, Physalis angulata, Origanum vulgare, Eucalyptus globulus, Mikania glomerata), and five plants with antibacterial activity help in the respiratory tract (Nasturtium officinale, Allium sativum, Schinus terebinthifolius, Adiantum capillus-veneris, Allium cepa). However, tuberculosis is a re-emerging disease, and it is necessary to adopt public policies that intensify and implement socio-educational measures for using herbal medicines as a complementary measure.

Sin embargo, la tuberculosis es una enfermedad reemergente siendo necesaria la adopción de políticas públicas que intensifiquen e implementen medidas socioeducativas para la implementación del uso de fitoterápicos como medida complementaria.

[Tuberculosis: the counterpoint of progress]. / Tuberculosis: el contrapunto del progreso.

Along history, infectious diseases have had a direct influence in the development of humanity, with tuberculosis showing a leading role. Despite this disease being the main cause of mortality among infectious diseases, it remains neglected and constitutes a serious public health problem, especially among the poorest countries in the world. Tuberculosis greatest importance goes beyond Medicine, and a holistic view of the disease allows us to comprehend the economic and social development of a nation. Despite a historically successful control program in Chile, current figures are not auspicious and force upon us the need to address this problem with a multidisciplinary approach. The medical physician is required to put again into practice the fundamental principle of Medicine, Semiology to contribute to the control of tuberculosis.

Risk of Reactivation of Latent Tuberculosis in Psoriasis Patients on Biologic Therapies: A Retrospective Cohort from a Tertiary Care Centre in Northern Italy.

Psoriatic patients with latent tuberculosis infection and properly treated active tuberculosis need careful management when prescribing modern biological drugs. Although data and guidelines regarding tumour necrosis factor-α inhibitors advise caution and initiation of prophylactic therapy in patients with latent tuberculosis infection, the same indications do not seem to find equal force for interleukin (IL)-23 and IL-17 inhibitors. In order to evaluate the risk of reactivation in patients with latent tuberculosis infection or properly treated active tuberculosis, an observational retrospective study was conducted on the population referred to our centre at Dermatologic Clinic of University of Turin, Italy. In the last 10 years at the clinic 19 psoriatic patients were found to be at risk of tuberculosis reactivation: 10 patients were QuantiFERON- TB-positive at baseline, 2 became positive during treatment, 6 reported prior tuberculous infection, and 1 was QuantiFERON-TB-negative at baseline and developed disseminated tuberculosis during treatment with anti-tumour necrosis factor-α. Overall, 10.5% of this group of patients developed active tuberculosis; however, stratifying by biologic therapy, zero cases were observed among patients treated with anti-IL-17, -23, or -12/23 over a relatively long follow-up (48.1 months) A review of the available literature following our experience confirms the increased risk of tuberculosis reactivation with tumour necrosis factor-α inhibitors. Concerning anti-IL-23 and IL-17 drugs, available data showed high safety in patients at risk of tuberculosis reactivation. Screening of patients who should be taking IL-17 and IL-23 inhibitors is recommended for public health purposes. In case of a positive result with these therapies, consulting with an infectious diseases specialist is suggested in order to weigh up the risks and benefits of prophylactic treatment.

Tuberculosis: el contrapunto del progreso / Tuberculosis: the counterpoint of progress

Resumen A lo largo de la historia, las enfermedades infecciosas han influido directamente en el desarrollo de la humanidad y en este proceso, la tuberculosis ha tenido un rol protagónico. Esta enfermedad mata más seres humanos que cualquier otra de causa infecciosa y, a pesar de esto, continúa siendo una entidad olvidada y un grave problema de salud pública, sobre todo en las naciones más pobres. La trascendencia de la tuberculosis va más allá del ámbito médico y una visión holística de ella nos permite comprender el grado de desarrollo económico y social de un Estado. Si bien Chile mantenía un programa de control históricamente exitoso, las cifras actuales no son auspiciosas y obligan a analizar el problema desde una mirada multidisciplinaria. Es en este marco que planteamos que el médico clínico, para aportar en el control de la enfermedad, debe poner nuevamente en práctica uno de los principios básicos de la Medicina: la semiología.

Impact of Vitamin D in Prophylaxis and Treatment in Tuberculosis Patients.

Vitamin D plays a crucial role in many infectious diseases, such as tuberculosis (TB), that remains one of the world's top infectious killers with 1.5 million deaths from TB in 2021. Vitamin D suppresses the replication of Mycobacterium tuberculosis in vitro and showed a promising role in TB management as a result of its connection with oxidative balance. Our review encourages the possible in vivo benefit of a joint administration with other vitamins, such as vitamin A, which share a known antimycobacterial action with vitamin D. However, considering the low incidence of side effects even at high dosages and its low cost, it would be advisable to assess vitamin D level both in patients with active TB and high-risk groups and administer it, at least to reach sufficiency levels.

WHO target product profiles for TB preventive treatment.

BACKGROUND: The WHO has developed target product profiles (TPPs) describing the most appropriate qualities for future TPT regimens to assist developers in aligning the characteristics of new treatments with programmatic requirements.METHODS: A technical consultation group was convened by the WHO to determine regimen attributes with greatest potential impact for patients (i.e., improved risk/benefit profile) and populations (i.e., reduction in transmission and TB prevalence). The group categorised regimen attributes as 'priority´ or 'desirable´; and defined for each attribute the minimum requirements and optimal targets.RESULTS: Nine priority attributes were defined, including efficacy, treatment duration, safety, drug-drug interactions, barrier to emergence of drug resistance, target population, formulation, dosage, frequency and route of administration, stability and shelf life. Regimens meeting optimal targets were characterised, for example, as having superior efficacy, treatment duration of ≤2 weeks, and improved tolerability and safety profile compared with current regimens. The four desirable attributes included regimen cost, safety in special populations, treatment adherence and need for drug susceptibility testing in the index patient.DISCUSSION: It may be difficult for a single regimen to satisfy all characteristics so regimen developers may have to consider trade-offs. Additional operational aspects may be relevant to the feasibility and public health impact of new TPT regimens.

Vitamin D and tuberculosis in children: a role in the prevention or treatment of the disease?

Despite the growing number of published studies, the role of vitamin D in the prevention or treatment of tuberculosis remains unclear. In this review we analyze current scientific literature to provide evidence about the relationship between vitamin D and TB, with a special focus on the pediatric population. While in vitro studies have shown relevant antimycobacterial immune-stimulatory and immunosuppressive effects of vitamin D, this has not panned out in vivo with active TB. On the contrary, there is some evidence that this tool could work as prevention - both against TB infection as well as progression from latent to active infection. However, only a few studies have evaluated this correlation in children. The potential link between tuberculosis and vitamin D levels is promising. If effective, vitamin D supplementation of at-risk populations would be an affordable public health intervention, particularly in light of the worldwide increase in identified TB cases and drug-resistance. Vitamin D might represent a new, affordable, safe and easy to access drug for the prevention and treatment of TB. For stronger evidence, considering the features of infection (relative low incidence of reactivation of latent infection in immunocompetent patients) we need clinical trials with large numbers of participants conducted in endemic regions with a prolonged follow-up time.

TB free India: Reaching the unreached tribal population under National Tuberculosis Elimination Programme.

India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Tuberculosis and Diabetes in India: Stakeholder Perspectives on Health System Challenges and Opportunities for Integrated Care.

BACKGROUND: India has a dual burden of tuberculosis (TB) and diabetes mellitus (DM). Integrated care for TB/DM is still in the early phase in the country and can be considerably enhanced by understanding and addressing the challenges identified from stakeholders' perspectives. This study explored the challenges and opportunities at individual, health system and policy level for integrated care of TB/DM comorbidities in India. METHODS: We used an outlier case study approach and conducted stakeholder interviews and focus group discussions with relevant program personnel including field staff and program managers of TB and DM control programs as well as officials of partners in Indian states, Kerala and Bihar. RESULTS: The integrated management requires strengthening the laboratory diagnosis and drug management components of the two individual programs for TB and DM. Focused training and sensitization of healthcare workers in public and private sector across all levels is essential. A district level management unit that coordinates the two vertical programs with a horizontal integration at the primary care level is the way forward. Substantial improvement in data infrastructure is essential to improve decision-making process. CONCLUSION: Bi-directional screening and management of TB/DM comorbidities in India requires substantial investment in human resources, infrastructure, drug availability, and data infrastructure.

Nutritional Supplementation Would Be Cost-Effective for Reducing Tuberculosis Incidence and Mortality in India: The Ration Optimization to Impede Tuberculosis (ROTI-TB) Model.

BACKGROUND: Undernutrition is the leading cause of tuberculosis (TB) in India and is associated with increased TB mortality. Undernutrition also decreases quality of life and economic productivity. METHODS: We assessed the cost-effectiveness of providing augmented rations to undernourished Indians through the government's Targeted Public Distribution System (TPDS). We used Markov state transition models to simulate disease progression and mortality among undernourished individuals in 3 groups: general population, household contacts (HHCs) of people living with TB, and persons living with human immunodeficiency virus (HIV). The models calculate costs and outcomes (TB cases, TB deaths, and disability-adjusted life years [DALYs]) associated with a 2600 kcal/day diet for adults with body mass index (BMI) of 16-18.4 kg/m2 until they attain a BMI of 20 kg/m2 compared to a status quo scenario wherein TPDS rations are unchanged. We employed deterministic and probabilistic sensitivity analyses to test result robustness. RESULTS: Over 5 years, augmented rations could avert 81% of TB cases and 88% of TB deaths among currently undernourished Indians. Correspondingly, this intervention could forestall 78% and 48% of TB cases and prevent 88% and 70% of deaths among undernourished HHCs and persons with HIV, respectively. Augmented rations resulted in 10-fold higher resolution of undernutrition and were highly cost-effective with (incremental cost-effectiveness ratio [ICER] of $470/DALY averted). ICER was lower for HHCs ($360/DALY averted) and the HIV population ($250/DALY averted). CONCLUSIONS: A robust nutritional intervention would be highly cost-effective in reducing TB incidence and mortality while reducing chronic undernutrition in India.

Improving child tuberculosis contact identification and screening in Lesotho: Results from a mixed-methods cluster-randomized implementation science study.

BACKGROUND: Child tuberculosis (TB) contact management is recommended for preventing TB in children but its implementation is suboptimal in high TB/HIV-burden settings. The PREVENT Study was a mixed-methods, clustered-randomized implementation study that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve child TB contact management in Lesotho, a high TB burden country. METHODS: Ten health facilities were randomized to CBI or standard of care (SOC). CBI holistically addressed the complex provider-, patient-, and caregiver-related barriers to prevention of childhood TB. Routine TB program data were abstracted from TB registers and cards for all adult TB patients aged >18 years registered during the study period, and their child contacts. Primary outcome was yield (number) of child contacts identified and screened per adult TB patient. Generalized linear mixed models tested for differences between study arms. CBI acceptability was assessed via semi-structured in-depth interviews with a purposively selected sample of 20 healthcare providers and 28 caregivers. Qualitative data were used to explain and confirm quantitative results. We used thematic analysis to analyze the data. RESULTS: From 01/2017-06/2018, 973 adult TB patients were recorded, 490 at CBI and 483 at SOC health facilities; 64% male, 68% HIV-positive. At CBI and SOC health facilities, 216 and 164 child contacts were identified, respectively (p = 0.16). Screening proportions (94% vs. 62%, p = 0.13) were similar; contact yield per TB case (0.40 vs. 0.20, p = 0.08) was higher at CBI than SOC health facilities, respectively. CBI was acceptable to caregivers and healthcare providers. CONCLUSION: Identification and screening for TB child contacts were similar across study arms but yield was marginally higher at CBI compared with SOC health facilities. CBI scale-up may enhance the ability to reach and engage child TB contacts, contributing to efforts to improve TB prevention among children.
