Harris RC, Sumner T, Knight GM, Zhang H, White RG. Potential impact of tuberculosis vaccines in China, South Africa, and India. Sci Transl Med 2020; 12:eaax4607. [PMID: 33028708 DOI: 10.1126/scitranslmed.aax4607] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 11/12/2019] [Accepted: 09/16/2020] [Indexed: 12/11/2022]
Abstract
More effective tuberculosis vaccines are needed to help reach World Health Organization tuberculosis elimination goals. Insufficient evidence exists on the potential impact of future tuberculosis vaccines with varying characteristics and in different epidemiological settings. To inform vaccine development decision making, we modeled the impact of hypothetical tuberculosis vaccines in three high-burden countries. We calibrated Mycobacterium tuberculosis (M.tb) transmission models to age-stratified demographic and epidemiological data from China, South Africa, and India. We varied vaccine efficacy to prevent infection or disease, effective in persons M.tb uninfected or infected, and duration of protection. We modeled routine early-adolescent vaccination and 10-yearly mass campaigns from 2025. We estimated median percentage population-level tuberculosis incidence rate reduction (IRR) in 2050 compared to a no new vaccine scenario. In all settings, results suggested vaccines preventing disease in M.tb-infected populations would have greatest impact by 2050 (10-year, 70% efficacy against disease, IRR 51%, 52%, and 54% in China, South Africa, and India, respectively). Vaccines preventing reinfection delivered lower potential impact (IRR 1, 12, and 17%). Intermediate impact was predicted for vaccines effective only in uninfected populations, if preventing infection (IRR 21, 37, and 50%) or disease (IRR 19, 36, and 51%), with greater impact in higher-transmission settings. Tuberculosis vaccines have the potential to deliver substantial population-level impact. For prioritizing impact by 2050, vaccine development should focus on preventing disease in M.tb-infected populations. Preventing infection or disease in uninfected populations may be useful in higher transmission settings. As vaccine impact depended on epidemiology, different development strategies may be required.

Abstract
BACKGROUND The prevalence, incidence, and mortality rates of tuberculosis (TB) have declined steadily in Korea since 1965. This study aimed to identify the characteristics and provide quantitative analysis of published medical literatures on TB written by researchers based in Korea. METHODS We conducted a systematic literature search via the Web of Science database for articles in Science Citation Index (Expanded) journals, on TB, and published by researchers based in Korea, from inception to 2017. All articles were analyzed by publication year, publishing journal, article type, study design, research institutes, and research funds. RESULTS During the study period, we identified 1,101 articles and included them for analysis. The first was published in 1979, while 105 were published in 2017. Between 1979 and 2017, the compound annual growth rate of TB articles by researchers based in Korea was 13.0%. Among 1,101 articles, 682 (61.9%) were clinical research and 383 (34.8%) were basic research. Studies with cross-sectional design were the most common type among the clinical research, while biochemistry was the most common field among the basic research. The number of articles dealing with diagnostics or treatment has increased significantly, although the number of articles on vaccines, and on operational and public health, has only a slight increase. The Ministry of Health and Welfare of Korea funded studies yielding 178 (20.1%) articles. CONCLUSION Articles on TB, especially those on clinical aspects, and published by researchers based in Korea have been increasing rapidly since 1979.

Abstract
OBJECTIVES To assess a multicomponent intervention to improve private practitioners (PPs) involvement in referral of presumptive pulmonary TB (PTB) cases to the Revised National TB Control Programme (RNTCP) for sputum examination. METHODS Randomised controlled trial. We randomly allocated all 189 eligible PPs in Tumkur city, South India, to intervention or control arm. The intervention, implemented between December 2014 and January 2016, included two sets of activities, one targeted at health system strengthening (building RNTCP staff capacity to collaborate with PPs, provision of feedback on referrals through SMS) and one targeted at intervention PPs (training in RNTCP, provision of referral pads and education materials and monthly visits to PPs by RNTCP staff). Crude and adjusted referral and PTB case-finding rate ratios were calculated with negative binomial regression. RESULTS PPs referred 836 individuals (548 from intervention and 169 from control arm PPs) of whom 176 were diagnosed with bacteriologically confirmed PTB. The proportion (95% confidence interval) of referring PPs [0.59 (0.49, 0.68) vs. 0.42 (0.32, 0.52) in the intervention and control arm, respectively], mean referral rate per PP-year [(5.7 (3.8, 8.7) vs. 1.8 (1.2, 2.8)] and smear-positive PTB case-finding rate per PP-year [(1.5 (0.9, 2.2) vs. 0.6 (0.3, 0.9)] were significantly higher in the intervention than the control arm. Stratifying by qualification, a statistically significant difference in the above indicators remained only among GPs and internists. Overall, surgeons, paediatricians and gynaecologists referred few patients. PP referrals contributed to 20% of the sputum smear positive PTB cases detected by RNTCP in Tumkur city (14% were from intervention arm PPs). CONCLUSIONS We demonstrated the effectiveness of a health system-oriented intervention to improve PP's referrals of presumptive PTB cases to RNTCP.

Abstract
Since 2003, the Lilly Foundation has supported the noncommercial Lilly MDR-TB Partnership, which involves more than 45 local, national, global, and nongovernmental organizations and governments. The aim of the Lilly MDR-TB Partnership is to achieve significant global impact on multidrug-resistant tuberculosis (MDR-TB) by addressing a series of important local health care needs in highly affected countries: China, India, Russia, and South Africa. The main focus of activities during 2012–2016 was on community needs in primary care. Supported projects seek to make meaningful and measurable progress toward global and national TB objectives. The partnership programs share an overall conceptual approach known as “research, report, advocate”, based on the piloting of novel approaches on a small scale, with outcomes assessed at early stages. The results are analyzed and communicated to governments, health-policy experts, and local and national stakeholders, including those in other countries facing similar MDR-TB challenges. For successful, cost-effective initiatives, the analysis is used as support when advocating for the scaling up of initiatives to regional or national levels. This article discusses representative examples of projects supported by the Lilly MDR-TB Partnership in the time period 2012–2016. The examples illustrate the potential for globally informed, locally designed primary-care collaborations to strengthen health care systems and support TB policies and offer observations to inform future health care public–private partnerships.

Abstract
Tuberculosis case management practices of private practitioners in low- and middle-income countries are commonly not in compliance with treatment guidelines, thus increasing the risk of drug resistance. National Tuberculosis control programs have long been encouraged to collaborate with private providers to improve compliance, but there is no example yet of a sustained, large scale collaborations with private practitioners in these settings. Regulations have long been realized as a potential response to poor quality care, however there has been a lack of interest from the international actors to invest in stronger regulation of private providers in these countries due to limited evidence and many implementation challenges. Regulatory strategies have now evolved beyond the costly conventional form of command and control. These new strategies need to be tested for addressing the challenge of poor quality care among private providers. Multilateral and bilateral funding agencies committed to tuberculosis control need to invest in facilitating strengthening government’s capacity to effectively regulate private providers.

Abstract
BACKGROUND Public-private mix (PPM), recommended by the World Health Organization (WHO), was introduced to cope with the tuberculosis (TB) epidemic worldwide. In many developing countries, PPM has played a powerful role in TB control, while in others it has failed to meet expectations. Thus we performed a systematic review to determine the mechanisms used by global PPM programs implemented in different countries and to evaluate their performance. METHODS A comprehensive search of the current literature for original studies published up to May 2014 was done using electronic databases and online resources; these publications were then screened using rigorous criteria. Descriptive information and evaluative outcomes data were extracted from eligible studies for synthesis and analysis. RESULTS A total of 78 eligible studies were included in the final review. These assessed 48 PPM TB programs worldwide, subsequently categorized into three mechanisms based on collaborative characteristics: support, contract, and multi-partner group. Furthermore, we assessed the effectiveness of PPM programs against six health system themes, including utilization of the directly observed treatment strategy (DOTS), case detection, treatment outcomes, case management, costs, and access and equity, under the different collaborative mechanisms. Analysis of the comparative studies suggested that PPM could improve overall outcomes of a TB service, and multiple collaborative mechanisms may significantly promote case detection, treatment, referral, and service accessibility, especially in resource-limited areas. However, the less positive outcomes of several programs indicated limited funding and poor governance to be the predominant reasons. CONCLUSIONS PPM is a promising strategy to strengthen global TB care and control, but is affected by contextual characteristics in different areas. The scaling-up of PPM should contain essential commonalities, particularly substantial financial support and continuous material input. Additionally, it is important to improve program governance and training for the health providers involved, through integrated collaborative mechanisms.

Abstract
Background Research investments are essential to address the burden of disease, however allocation of limited resources is poorly documented. We systematically reviewed the investments awarded by funding organisations to UK institutions and their global partners for infectious disease research. Methodology/Principal Findings Public and philanthropic investments for the period 1997 to 2010 were included. We categorised studies by infectious disease, cross-cutting theme, and by research and development value chain, reflecting the type of science. We identified 6165 funded studies, with a total research investment of UK £2.6 billion. Public organisations provided £1.4 billion (54.0%) of investments compared with £1.1 billion (42.4%) by philanthropic organisations. Global health studies represented an investment of £928 million (35.7%). The Wellcome Trust was the leading investor with £688 million (26.5%), closely followed by the UK Medical Research Council (MRC) with £673 million (25.9%). Funding over time was volatile, ranging from ∼£40 million to ∼£160 million per year for philanthropic organisations and ∼£30 million to ∼£230 million for public funders. Conclusions/Significance Infectious disease research funding requires global coordination and strategic long-term vision. Our analysis demonstrates the diversity and inconsistent patterns in investment, with volatility in annual funding amounts and limited investment for product development and clinical trials.

Abstract
The vision of Nigeria’s immunization program is to reach and sustain routine immunization coverage of greater than 90% for all vaccines by 2020. In order to achieve this, Abia state embarked on a unique private-public partnership (PPP) between private health facilities and the Abia state ministry of health. The aim of this partnership was to collaborate with private health facilities to provide free childhood immunization services in the state - the first of its kind in Nigeria. This is a retrospective study of the 2011 Abia state, Nigeria monthly immunization data. In the 4 local governments operating the PPP, 45% (79/175) of the health facilities that offered immunization services in 2011 were private health facilities and 55% (96/175) were public health facilities. However, 21% of the immunization services took place in private health facilities while 79% took place in public health facilities. Private health facilities were shown to have a modest contribution to immunization in the 4 local governments involved in the PPP. Efforts should be made to expand PPP in immunization nationally to improve immunization services in Nigeria.

Abstract
Multidrug-resistant (MDR) tuberculosis (TB) denotes bacillary resistance to at least isoniazid and rifampicin. Extensively drug-resistant (XDR) TB is MDR-TB with additional bacillary resistance to any fluoroquinolone and at least one second-line injectable drugs. Rooted in inadequate TB treatment and compounded by a vicious circle of diagnostic delay and improper treatment, MDR-TB/XDR-TB has become a global epidemic that is fuelled by poverty, human immunodeficiency virus (HIV) and neglect of airborne infection control. The majority of MDR-TB cases in some settings with high prevalence of MDR-TB are due to transmission of drug-resistant bacillary strains to previously untreated patients. Global efforts in controlling MDR-TB/XDR-TB can no longer focus solely on high-risk patients. It is difficult and costly to treat MDR-TB/XDR-TB. Without timely implementation of preventive and management strategies, difficult MDR-TB/XDR-TB can cripple global TB control efforts. Preventive strategies include prompt diagnosis with adequate TB treatment using the directly observed therapy, short-course (DOTS) strategy and drug-resistance programmes, airborne infection control, preventive treatment of TB/HIV, and optimal use of antiretroviral therapy. Management strategies for established cases of difficult MDR-TB/XDR-TB rely on harnessing existing drugs (notably newer generation fluoroquinolones, high-dose isoniazid, linezolid and pyrazinamide with in vitro activity) in the best combinations and dosing schedules, together with adjunctive surgery in carefully selected cases. Immunotherapy may also have a role in the future. New diagnostics, drugs and vaccines are required to meet the challenge, but science alone is insufficient. Difficult MDR-TB/XDR-TB cannot be tackled without achieving high cure rates with quality DOTS and beyond, and concurrently addressing poverty and HIV.

Acceptability and effectiveness of the storekeeper-based TB referral system for TB suspects in sub-districts of Lilongwe in Malawi. PLoS One 2012; 7:e39746.

Abstract
BACKGROUND Early access to tuberculosis diagnosis and treatment remains a challenge in developing countries. General use of informal providers such as storekeepers is common. The aim of this study was to determine the effectiveness and acceptability of a storekeeper-based referral system for TB suspects in urban settings of Lilongwe, Malawi. METHODS The referral system intervention was implemented in two sub-districts. This was evaluated using a pre and post comparison as well as comparison with a third sub-district designated as the control. The intervention included training of storekeepers to detect and refer clients with chronic cough using predesigned referral letters along with monitoring and supervision. Data from a community based chronic cough survey and an audit of health centre records were used to measure its effectiveness. Focus group discussions and in-depth interviews were carried out to document acceptability of the intervention with the different stakeholders. RESULTS Following the intervention, the mean patient delay appeared lower in the intervention than comparison areas (2.14 weeks (SD 5.8) vs 8.8 weeks (SD 15.1)). However, after adjusting for confounding variables this difference was not significant (p = 0.07). After the intervention the proportion of the population diagnosed with smear positive TB in the intervention sites (1.2 per 1000) was significantly higher than in the comparison area (0.6 per 1000, p<0.01) even after adjusting for sex and age. Qualitative findings suggested that (a) the referral letters triggered health workers to ask patients to submit sputum for TB diagnosis (b) the approach may be sustainable as the referral role was linked to the livelihood of the storekeepers. CONCLUSION The study suggests that the referral system with storekeepers is sustainable and effective in increasing smear positive TB case notification. Studies that assess this approach for control of other diseases along with collection of specimens by storekeepers or similar providers are needed.

Abstract
India and China are two Asian super-powers with developing economies carried on the shoulders of their booming populations. This growth can only be sustained by nurturing their "human resource". However increasing reports of insufficient public health (PH) initiatives in India when compared to the aggressive PH system of China may prove to be the Achilles' heels for India. This review compares the PH system in India and China for combating Tuberculosis (TB), the disease responsible for maximum mortality and morbidity by a single infectious agent. While China has acknowledged the disease load and thereafter has methodically improved its reporting, detection, diagnosis and treatment, India is still in denial of the imminent health risk. The Indian PH system still considers TB as a "facultative" disease for which the required control measures are already in place and functioning. Globally, India and China recorded the highest Multi-Drug Resistant TB (MDR) cases notified in 2010 (64000 and 63000, respectively). Additionally non-government sources reported extremely high proportions of MDR in India. Here we have compared the medical, social and economic approaches of the two nations towards better management and control of TB. Does India have lessons to learn from China?

Abstract
Background The Global Plan to Stop TB estimates funding required in low- and middle-income countries to achieve TB control targets set by the Stop TB Partnership within the context of the Millennium Development Goals. We estimate the contribution and impact of Global Fund investments under various scenarios of allocations across interventions and regions. Methodology/Principal Findings Using Global Plan assumptions on expected cases and mortality, we estimate treatment costs and mortality impact for diagnosis and treatment for drug-sensitive and multidrug-resistant TB (MDR-TB), including antiretroviral treatment (ART) during DOTS for HIV-co-infected patients, for four country groups, overall and for the Global Fund investments. In 2015, China and India account for 24% of funding need, Eastern Europe and Central Asia (EECA) for 33%, sub-Saharan Africa (SSA) for 20%, and other low- and middle-income countries for 24%. Scale-up of MDR-TB treatment, especially in EECA, drives an increasing global TB funding need – an essential investment to contain the mortality burden associated with MDR-TB and future disease costs. Funding needs rise fastest in SSA, reflecting increasing coverage need of improved TB/HIV management, which saves most lives per dollar spent in the short term. The Global Fund is expected to finance 8–12% of Global Plan implementation costs annually. Lives saved through Global Fund TB support within the available funding envelope could increase 37% if allocations shifted from current regional demand patterns to a prioritized scale-up of improved TB/HIV treatment and secondly DOTS, both mainly in Africa − with EECA region, which has disproportionately high per-patient costs, funded from alternative resources. Conclusions/Significance These findings, alongside country funding gaps, domestic funding and implementation capacity and equity considerations, should inform strategies and policies for international donors, national governments and disease control programs to implement a more optimal investment approach focusing on highest-impact populations and interventions.

Abstract
INTRODUCTION Despite concerted efforts to scale up tuberculosis control with large amounts of international financing in the last 2 decades, tuberculosis continues to be a social issue affecting the world's most marginalized and disadvantaged communities. This includes prisoners, estimated at about 10 million globally, for whom tuberculosis is a leading cause of mortality and morbidity. The Global Fund to Fight AIDS, Tuberculosis and Malaria has emerged as the single largest international donor for tuberculosis control, including funding support in delivering tuberculosis treatment for the confined population. METHODS The Global Fund grants database, with an aggregate approved investment of $21.7 billion in 150 countries by the end of 2010, was reviewed to identify tuberculosis and human immunodeficiency virus/tuberculosis grants and activities that monitored the delivery of tuberculosis treatment and support activities in penitentiary settings. The distribution and trend of number of countries with tuberculosis prison support was mapped by year, geographic region, tuberculosis or multidrug-resistant tuberculosis burden, and prison population rate. We examined the types of grant recipients managing program delivery, their performance, and the nature and range of services provided. RESULTS Fifty-three of the 105 countries (50%) with Global Fund-supported tuberculosis programs delivered services within prison settings. Thirty-two percent (73 of 228) of tuberculosis grants, representing $558 million of all disbursements of Global Fund tuberculosis support by the end of 2010, included output indicators related to tuberculosis services delivered in prisons. Nearly two-thirds (64%) of these grants were implemented by governments, with the remaining by civil society and other partners. In terms of services, half (36 of 73) of grants provided diagnosis and treatment and an additional 27% provided screening and monitoring of tuberculosis for prisoners. The range of services tracked was limited in scope and scale, with 69% offering only 1 type of service and less than one-fifth offering 2 types of service. CONCLUSIONS This study is a preliminary attempt to examine Global Fund investments in the fight against tuberculosis in prison settings. Tuberculosis services delivered in prisons have increased in the last decade, but systematic information on funding levels and gaps, services provided, and cost-effective delivery models for delivering tuberculosis services in prisons are lacking.
