1. Introduction
“When you have cancer, everyone
will feel sorry for you. But when you have tuberculosis, people
are afraid, people look down on you.”
Olga Klymenko, former tuberculosis
patient
1.1. Procedure
1. On 11 October 2016, the Committee
on Social Affairs, Health and Sustainable Development tabled a motion
for a resolution on “Inquiry into growing antimicrobial resistance
in Europe”. The motion was referred to the committee for report,
and, as its initiator, I was appointed rapporteur on 26 January 2017.
2. Antimicrobial resistance (AMR) is the process by which bacteria
evolve to become resistant to medicines used to treat the infections
they cause, thus rendering these medicines ineffective. In an introductory memorandum
presented in April 2017, I stressed that tuberculosis was at the
origin of one third of deaths from AMR worldwide, and that Europe
was home to the world’s fastest growing drug-resistant tuberculosis
(DR-TB) epidemic. In September 2017, the committee held a hearing
with the participation of a former TB patient from Ukraine, Ms Olga
Klymenko, experts from the Organisation for Economic Cooperation
and Development, and the Global TB Caucus.
The hearing revealed the true
magnitude of the suffering caused by the disease and in particular
its social, economic and psychological impact on patients. In December
2017, in view of the increasing political exposure in recent and
upcoming years of the fight against TB (see below) and Europe’s particularly
high disease burden with regard to multidrug-resistant tuberculosis
(MDR-TB), I proposed focusing on drug-resistant TB in the report,
which the committee ultimately agreed to.
3. In preparing the report, I carried out fact-finding visits
to Azerbaijan and Norway, where I held meetings with a range of
stakeholders working in the national TB response, including parliamentarians,
government and civil society representatives, and medical experts.
These visits allowed me to grasp how these two countries with very
different levels of TB incidence are addressing this issue and to
identify some best practices. I should like to thank all the parties
involved in the discussions for their valuable contributions, and
the delegations of both parliaments and their secretariats for the
excellent organisation of my visits.
1.2. Tuberculosis on the political
agenda
4. In September 2016, world leaders
met to discuss the response to AMR at a United Nations high-level meeting,
and agreed that the international community must take urgent action
to prevent its advance, as it threatens effective treatment for
many common infections, including TB. A few months later, noting
the impact of AMR, in particular on the treatment of TB, the United
Nations General Assembly decided to hold a high-level meeting on
the fight against TB in 2018.
5. In November 2017, the World Health Organization (WHO) convened
a global ministerial conference on “Ending TB in the Sustainable
Development Era”, at which Ministers of Health from across the world
met to discuss how to respond to the epidemic. The conference resulted
in collective commitment to ramp up action on four fronts: achieving
universal health coverage by strengthening health systems and improving
access to people-centred TB prevention and care; mobilising sufficient
and sustainable financing to close gaps in implementation and research;
advancing research and development of new tools to diagnose, treat
and prevent TB; and build accountability through a framework to
track and review progress on ending TB.
6. The upcoming United Nations high-level meeting on TB is an
unprecedented step forward by governments and all partners engaged
in the fight against TB. It is a historic opportunity to push for
a strong and ambitious political declaration which would give the
necessary impetus for concrete action to end TB, thus saving millions
of lives. This report is designed as the Parliamentary Assembly’s
contribution to this first-ever United Nations high-level meeting
on TB.
2. Tuberculosis – the world’s
leading infectious killer
“Tuberculosis is a disease that
affects all aspects of your life, not just your health.”
Stefan Radut, tuberculosis patient
2.1. Facts about tuberculosis
7. TB is an airborne infectious
disease, caused by the bacterium Mycobacterium Tuberculosis, which
is spread by coughing or sneezing and mostly affects the lungs,
although TB bacteria can be present and cause illness in any part
of the body. Symptoms can include a persistent cough, weight loss,
fever, pain and fatigue, although other non-specific symptoms can
be present, especially in children. In 2016, TB caused 1.7 million deaths
worldwide, amongst which were 250 000 children, making it the world’s
leading infectious killer.
8. The treatment for standard (or drug-susceptible) TB lasts
at least six months, and comprises a combination of antibiotics
(a regimen). Multidrug-resistant tuberculosis (MDR-TB) is a form
of TB caused by bacteria that do not respond to isoniazid and rifampicin,
the two most powerful first-line anti-TB drugs. MDR-TB is treatable
and curable by using second-line drugs. However, the treatment is
much longer (up to two years of treatment), much more challenging
for patients, and far more expensive than the treatment for standard
TB. Patients not only face up to 14 000 pills over two years, but
also painful intravenous injections, and difficult side-effects,
including nausea, digestive issues and weakness, permanent disabilities
such as blindness and deafness, and psychological difficulties such
as depression, anxiety and even psychosis. Extensively drug-resistant
tuberculosis (XDR-TB) is a more serious form of MDR-TB caused by
bacteria that do not respond to the most effective second-line anti-TB
drugs, often leaving patients without any further treatment options.
9. It is estimated that about one quarter of the world's population
has been infected by TB bacteria. However, they are not ill (this
is known as latent TB) and cannot transmit the disease, as the TB
bacteria can only be transmitted by people with active TB. Only
a small proportion of those with latent TB (roughly 10%) will develop
the disease during their lifetime, the likelihood of developing
an active TB being higher for those with compromised immune systems.
Thus, people living with HIV
and other chronic illnesses that
impact the immune system, such as diabetes, are the groups with
a higher risk of falling ill. Moreover, while anyone can contract
the disease, people living in poverty, homeless people, people who
use drugs, prisoners and detainees, refugees and mobile populations
in general, face higher risks of exposure and infection compared to
the general population, mainly as a result of their living conditions.
10. A vaccine against TB (the Bacillus Calmette-Guérin vaccine
– BCG) is available, but it is only partially effective at protecting
infants and young children, and poorly protective against pulmonary
TB in adolescents and adults. There are also relatively efficient
preventive treatments for managing latent TB, which can prevent the
disease from activating, with an efficacy ranging between 60% to
90%.
2.2. What went wrong?
11. Why does a disease that is
preventable and curable still remain humanity’s deadliest infectious
killer, despite having been declared a global health emergency by
the WHO more than twenty years ago?
Something must have
gone terribly wrong.
12. While it is true that TB bacteria can hide in the body for
years, undetected, without developing into active TB; that it can
be mistaken for other illnesses that affect the lungs and respiratory
system, such as the flu or a cold, and that this leads to considerable
rates of misdiagnosis and delayed diagnosis; and that it is the
only major airborne drug-resistant infection – which makes it difficult
to control its spread –, these peculiarities cannot explain the
world’s collective failure in addressing TB.
13. In fact, national health-care systems’ failure to deliver
good quality TB treatment is one of the main reasons why the disease
continues to take so many lives. Inadequate and erratic treatment
made it possible for the disease to mutate into drug-resistant forms,
while large gaps in detecting TB,
out-dated health policies and weak
health-care infrastructures contributed to its transmission. Inextricably
linked with poverty, TB has continued to thrive disproportionally
in certain parts of the world, as regional and global inequalities
have increased. The constant lack of investment in research and
development for new drugs, vaccines and diagnostic tools, despite
a pressing need as the disease evolved into drug-resistant forms,
has exacerbated the problem. Today, the world is still far from
achieving target 3.3 of the Sustainable Development Goals – “end the
TB epidemic by 2030”. At current rates of progress, it will be 180
years before this target is achieved.
3. Europe: home to the world’s
highest rates of multidrug-resistant tuberculosis
14. TB was thought to be a disease
of the past in Europe.
Yet, the reality
is different, as the region sees around 900 new cases of TB each
day. The TB burden is, however, unequally distributed across the
region, new cases being highly concentrated in eastern and central
European countries. Europe also has the highest rates of MDR-TB
in the world, with an estimated one in five cases of MDR-TB worldwide
in 2015. Indeed, of the 30 countries identified by WHO as the highest
priority for tackling MDR-TB, nine are within the European Region.
Of
newly registered TB cases, 45% are among people between the ages
of 25 and 44, which has an impact on national economies, as this
demographic are the most economically productive.
15. Europe is also seeing the highest rates of MDR-TB in those
who have contracted TB for the first time, meaning that people are
contracting drug-resistant strains of the disease.
This is a trend which
should be cause for urgent concern, as the development of new tools
to treat MDR-TB significantly lags behind the rate at which it is
developing and spreading.
3.1. Underlying factors
16. There are a range of factors
contributing to the high rates of MDR-TB in Europe, amongst them
the continued out-dated practice of excessive hospitalisation
and
a lack of a people-centred approach to care – a model of care which
takes into account not only medication, but everything a patient
may need to complete their treatment, such as social, psychological
and financial support. TB patients are often kept in hospital for an
unnecessarily long time, despite most of them ceasing to be infectious
within two weeks of starting treatment. Many hospitals have poor
airborne infection-control measures, thus increasing the likelihood
of cross-infection between patients with different strains of TB
(including drug-resistant strains). Isolation in hospitals disrupts
patients’ social relations, in particular with their families,
negatively impacting
their psycho-social well-being which is critically important for
their recovery. Long-term hospitalisation is often incompatible with
work life, eventually leading to loss of income and disastrous financial
consequences.
17. Stigma associated with the disease and the resulting social
isolation also contribute to the high rates of MDR-TB in Europe,
as they seriously impact effective TB detection and treatment. In
fact, people with TB are often marginalised or rejected by their
community, employer, family or friends. Without any psycho-social support
to counter the effects of such stigma, people may be unwilling to
be diagnosed, or once diagnosed, can interrupt or stop their treatment
due to social difficulties and an inability to cope. The latter
is particularly problematic as non-adherence to treatment is one
of the main drivers of drug resistance, the reason being that unfinished
courses of medication have not destroyed the TB bacteria in the
body, meaning that the infection remains, or returns, and the bacteria
is then likely to have evolved to be resistant to the medication
used to treat it. Furthermore, as MDR-TB can only be detected by
laboratory tests, which remain underused, especially in the eastern
part of the region, it is estimated that there is a substantial
number of missing cases, which may also contribute to the transmission
of MDR-TB.
3.2. Region-specific challenges
3.2.1. Access to anti-TB drugs
18. In some eastern and central
European countries, patients encounter difficulties in accessing
the few existing new and promising second-line anti-TB drugs that
are available on the market, such as Bedaquiline® and Delamanid®,
which have been seen to be effective in treating DR-TB, and could
help reduce the use of painful and toxic drugs.
This is
due to a number of legal and bureaucratic obstacles, as well as
out-dated procurement policies which mean that States cannot procure
these drugs, which therefore cannot be used in treatment regimens.
19. Some difficulties also result from the geopolitical context.
For example, just a small number of TB patients in Ukraine can currently
access the above-mentioned two drugs because the regional distributor authorised
to request their registration and supply is a Russian-owned company.
The sanctions put in place since the Russian aggression prohibit
the procurement of goods and services from Russia paid for by public funds,
including for foreign goods supplied through Russian companies. Despite
efforts by the Ukrainian authorities, who have approached the relevant
pharmaceutical companies requesting them to change their distributor,
the problem has not yet been solved, leading to an unacceptable
delay for TB patients in Ukraine.
3.2.2. Conflict areas
20. Another specific challenge
for the European Region is the likely increase of TB incidence and
spread in conflict areas.
For obvious reasons, there
are delays in diagnosing and treating TB patients in these areas, where
health infrastructure is often severely weakened. This may lead
to the emergence of MDR-TB and complicate the management of the
disease. Experience shows that in conflict areas, if TB is neglected
it may quickly result in increased morbidity and mortality.
3.2.3. Vulnerable groups
21. Throughout Europe, in particular
people living with HIV, prisoners, refugees and migrants have a
higher probability than the general population of getting infected
with TB, developing the active disease and dying from it. As far
as HIV/AIDS is concerned, more than 160 000 people were newly diagnosed
with the disease in Europe in 2016, the highest number of people
ever newly diagnosed in one year since HIV case reporting began
in the 1980s.
Against
the background of a sharp increase in the HIV/TB co-infection rate
in the European Region (from 5.5% to 9% between 2011 and 2015),
efforts to tackle these two epidemics are critical, and in this
context, further integration of TB and HIV services should be explored.
As resistance to anti-TB drugs increases, the likelihood that those
TB patients who are also HIV positive will succumb to their illness
will increase as well.
22. As for migrants, those with latent TB are more likely to develop
the active disease in the country of destination due to a number
of factors, including their legal and employment situation, and
problems with access to health care. In some cases, migrants move
across borders after being diagnosed with active TB in their country
of origin.
23. For refugees and migrants with active and latent TB, it is
crucial to be diagnosed and receive the appropriate TB treatment
in the country of destination. It is also crucial for the country
of destination to detect those TB cases early enough so as to avoid
transmission amongst the population. To this end, a consensus paper
describing the minimum package of cross-border TB control and care
was prepared with input from the national TB control programme managers
of the WHO European Region and the Wolfheze 2011 Conference.
The package addresses the shortcomings
in this area and intends to improve the situation by covering several
aspects: political commitment (including the implementation of a
legal framework for TB cross-border collaboration), financial mechanisms
and adequate health-service delivery (prevention, infection control,
contact management, diagnosis and treatment and psycho-social support).
3.2.4. Health-care funding
24. As countries in eastern Europe
and central Asia become wealthier, they become ineligible for development
assistance and are expected to fully fund their health-care system,
including the national TB response. However, transitioning from
donor funding for health care is a complex process, and a number
of countries in the region do not have properly developed, funded
and implemented national TB strategies. Coupled with the problem
of already weak health-care infrastructures, it is very likely that
once external donors withdraw, valuable programmes to address TB
will cease to exist, perpetuating the chain of transmission, and undoing
any progress already made.
3.3. Examples of best practice
3.3.1. Azerbaijan
25. TB is a major health problem
in many of the world’s prisons, where infection rates can be more
than 10 times higher than in the general population. Europe is no
exception. During my visit to Azerbaijan, I had the opportunity
to meet representatives of the Ministry of Justice and the Ministry
of Health. Working in close collaboration, the two ministries have
put in place a successful TB programme in prisons. The programme includes,
amongst others, a routine screening of prisoners/detainees for TB,
raising awareness amongst prisoners/detainees and the prison staff
about the disease, and a specialised TB hospital for confirmed cases (including
a special laboratory) with separate wards for regular and resistant
forms of the disease to prevent transmission of resistant TB to
those people with drug-susceptible TB.
26. One of the most important objectives of the programme is to
ensure that the TB treatment is completed. When the treatment cannot
be completed within the penitentiary system (because of the release
of the prisoner/detainee), it is continued through a three-party
agreement between the Ministry of Justice, the Ministry of Health
and a local non-governmental organisation (NGO). The latter provides
different services, including follow-up of newly released TB patients,
to ensure that they complete their treatment, psychological support, and
sample collection for TB tests. Azerbaijan has achieved solid TB
cure rates through this prison programme, which has been internationally
recognised, including by an award from the International Corrections
and Prisons Association in 2013.
3.3.2. Norway
27. Norway has very few TB cases
every year (about 350-400) and an overwhelming majority of TB patients are
foreign-born. Against this background, the country has put in place
a strong and humane TB control programme, by introducing, amongst
others, an obligatory TB screening for all asylum seekers, as well
as all other migrants coming from countries where TB incidence is
high. TB treatment is free of charge for everyone, including all
migrants, independent of their legal status.
28. Norway has adopted an integrated approach whereby there is
effective collaboration between all stakeholders involved in the
fight against TB, including local authorities, civil society organisations
and health-care personnel. This collaboration between different
TB actors facilitated by “TB co-ordinators” is essential for a co-ordinated
and effective TB response. TB co-ordinators also follow patients
all the way through their treatment, provide them with emotional
support, and organise and facilitate the treatment plan meeting,
which is considered to be the cornerstone of treatment success.
In fact, all TB patients have an individual treatment plan setting
out the rules on where and when they will meet a health worker to
take their medicines.
The plan is established
so as to make it as convenient as possible for the patient to get
through the treatment period.
29. Norway is an excellent example demonstrating that TB can be
efficiently fought through the development and maintenance of a
strong, humane, integrated and people-centred TB control programme,
in particular for other high-income countries in Europe where TB
incidence is low.
4. Research and development
for new medicines, diagnostic tools and vaccines
30. There is a significant lack
of investment in research and development (R&D) for new TB medicines, diagnostic
tools and vaccines. The TB drug development field suffers from a
prolonged period of disinvestment by the pharmaceutical industry,
other than a few exceptions, leaving a thin pipeline of products
under development.
31. In fact, the current system of R&D does not work well
for a disease like TB, where there is little commercial incentive
for the production of new tools, because the greatest burden of
the disease falls on the poorest parts of the world. Even in low-
and middle-income countries, the groups most at risk of contracting
the disease tend to be the most marginalised and the poorest section
of society. In addition, TB treatments must be delivered as combination
therapies, usually using three or more antibiotics together. The
complex interaction of medicines means that the individual drugs
making up these regimens should ideally be developed as combinations
from early on during clinical testing, rather than once they are
finished and licensed single products. This poses technical and
commercial challenges.
Hence,
pharmaceutical producers are reluctant to invest the significant
R&D costs in order to bring new TB drugs onto the market.
32. While it is a global problem, Europe has a specific role in
changing this overall market failure for TB drugs, diagnostic tools
and vaccines, to avoid not only a significant number of unnecessary
deaths, but also a huge cost to national economies due to the expense
of treating MDR-TB and XDR-TB. Moreover, it should not be forgotten
that solutions that increase R&D for TB could also benefit the
problem of wider AMR, due to the need to develop multiple drugs
in order to treat TB, which could likely also be used to treat a
range of other illnesses.
33. European governments should invest more in R&D, by offering
incentives for innovation through sustained funding of early clinical
work, as well as through the so-called pull incentives that rewards
products for achieving market entry or important milestones along
the drug development pipeline.
34. Governments should also strengthen existing, and create new,
public-private partnerships for encouraging R&D. A major achievement
of the European Union in this context is the New Drugs for Bad Bugs programme,
the world’s biggest public-partnership in the field of AMR. The
programme, which was launched under the innovative medicines initiative
in 2012, has contributed to increasing the number of large European pharmaceutical
companies active in the AMR research area from 4 to 11 in the past
five years. Through calls-for-research specifically targeted at
small and medium-sized enterprises (SMEs), the European Commission has
also strengthened European SMEs involved in AMR-related research.
In the past decade, the number of SMEs working on AMR in the biopharmaceutical
companies from Europe innovating in AMR (BEAM Alliance) increased
from just a few to around 50.
35. In addition to new drugs, diagnostic tools and vaccines, there
is also a need to invest in new technologies that can simplify TB
treatment for patients, with a view to increasing treatment adherence
and success, considering that incomplete and erratic treatment is
one of the main drivers of drug resistance. An encouraging example
of such technology was presented to the participants of the 48th
World Conference on Lung Heath held in Guadalajara (Mexico), in
October 2017. The so-called
Wireless
Observed Therapy (WOT) is a digital, ingestible alternative to DOT, which
is the current gold standard for ensuring treatment adherence. Under WOT,
patients swallow an ingestible sensor made of minerals found in
food which breaks down in the body, releasing a sensor the size
of a grain of sand that sends data to a patch worn on the patient’s
chest. The patch stores the data (it provides a date and time-stamped
recording of medication ingestions) until it comes into contact
with a mobile device – a tablet or any mobile phone with Bluetooth
capacity. The mobile device encrypts the data and sends it via wireless
internet to the patients’ health-care provider, facilitating remote monitoring
and greatly relieving the burden of treatment on the patient.
5. The way forward for Europe
and the world
36. 2018 is a critically important
year for addressing the TB response at the global level, with increased political
momentum building as a result of governments coming together in
realisation of the growing threat to global public health posed
by TB. As the international community steps up efforts to tackle
the threat of TB, the European Region has a critical role to play
in addressing its own epidemic and showing global leadership in efforts
by the international community.
37. As far as the MDR-TB epidemic is concerned, experience shows
that a well-crafted public health response can improve things rapidly.
In fact,
The Lancet reports
that, following a rise in TB and MDR-TB in New York City in the
1980s, swift public health action caused MDR-TB incidence to drop
precipitously and more rapidly than drug-susceptible TB. “Such an
effective response to MDR-TB cannot focus on treating DR-TB alone
but include strong surveillance systems, drugs susceptibility testing
for all patients with TB, rapid linkage to effective treatment and
patient-centred care throughout the treatment course”.
38. Diagnosing TB quickly and accurately, so that people receive
appropriate treatment, is an imperative first step. Therefore, countries
should invest in actively looking for TB cases among high-risk populations,
such as people living with HIV.
Preventive therapy
to stop people with latent TB infection from developing active TB disease
should also be oriented towards these key populations.
39. Once diagnosed, it is crucial to ensure that patients are
adequately treated and monitored so that they finish their course
of medication. Completing treatment is crucial with a view to ensuring
recovery and preventing the development of resistant bacteria. As
the Azerbaijani example clearly shows, the involvement of civil
society in patient follow-up, treatment adherence and psycho-social
support can contribute to increasing TB cure rates. An effective
TB response should therefore involve civil society actors who can
provide TB education, treatment support and counselling to patients.
In order to combat the social isolation and stigma attached to TB,
in addition to providing psycho-social support, countries should
raise awareness about the disease amongst the general public and
work to debunk myths about the disease.
40. Moreover, countries should replace out-dated TB policies with
an efficient and people-centred model of TB care that is in line
with international guidelines from WHO. To this end, there should
be a shift in TB management from a centralised hospital-dominated
model to one embedded within communities and led by the primary-care
system. TB care should be provided mainly in the ambulatory and
community settings, together with appropriate infection control
measures to avoid cross-infection, and treatment support to facilitate adherence
to treatment.
Limiting hospitalisation
and prioritising treatment in ambulatory settings will reduce the
social and economic impact of the disease on patients, be less costly
for the State, and improve treatment outcomes.
41. In the coming years, the fragility of national health systems
in some countries in the region may be worsened by an overall reduction
in external donor funding for TB. Governments concerned should maintain sustained
action against TB, ensure sufficient and sustainable financing for
TB care in their national budget plans and focus their resources
on cost-effective and evidence-based solutions, in order not to
undo progress made in this area. International donors should be
involved in the planning and implementation of the transition, by
providing political and technical assistance and guidance to governments.
42. In order to effectively address the TB epidemic, the response
at the national level should involve all stakeholders, including
patients themselves (or those who have been affected by the disease),
health workers, caregivers and different service providers (e.g.
civil society organisations), and provide opportunities to work with
national decision-makers, such as government representatives and
members of national parliaments. This would allow accountability
and efficacy in the TB response, as the involvement of those who
have first-hand experience of the disease will help identify areas
where change is needed, as well as the appropriate action to be
taken in response to it.
43. All European countries should develop, fund and implement
a tailored national TB strategy, as is recommended by WHO.
The Lancet reports that the sustained
progress in declining TB incidence in the United Kingdom (30% decline
between 2011 and 2015) follows a combination of local, national,
and global action, as well as changes in migration patterns. A collaborative
national TB strategy was developed by Public Health England and
NHS (National Health Service) England between 2013 and 2015, while
concurrently implementing local and national TB control initiatives,
such as active case finding. The strategy involved ten areas of
action including two particular priorities: latent TB testing and
treatment of new entrants to the United Kingdom and targeted case
finding supported by management for vulnerable groups such as people
who are homeless, drug and alcohol users, and those in contact with
the criminal justice system.
44. If the ambitious vision articulated in Sustainable Development
Goal 3.3 is to be achieved, with many unnecessary deaths and huge
costs to the regional and global economy averted, European States
must work together, with low TB incidence countries showing greater
solidarity with high TB incidence countries. Low TB incidence countries
should also maintain awareness and commitment to TB control, with
a view to ensuring the further elimination of TB. We cannot afford
to be complacent when it comes to TB control. If we fail to sustain action,
re-emergence of TB is one of the few certainties.
45. The United Nations high-level meeting on TB will provide a
platform for these commitments to be made. This is the first time
TB has been prioritised for the attention of Heads of State from
across the world, and every effort should therefore be made to maximise
the impact of this meeting. Therefore, every Head of State from the
Council of Europe member States should attend the United Nations
high-level meeting on TB in New York in September 2018, and support
the agreement of an independent, multi-sectoral accountability framework
to ensure that all governments and stakeholders deliver on the commitments
made.
