Pulmonary Infections

The Food and Drug Administration has approved Xofluza (baloxavir marboxil) for the treatment of acute uncomplicated influenza in people aged 12 years or older who have been symptomatic for 48 hours or less.

The FDA approval is based on results from two randomized, clinical trials. In both trials, patients who received Xofluza experienced a shorter duration until alleviation of symptoms, compared with patients who received a placebo. In the second trial, patients who received Xofluza and patients who received another approved antiviral influenza medication experienced similar durations until symptom alleviation.

“When treatment is started within 48 hours of becoming sick with flu symptoms, antiviral drugs can lessen symptoms and shorten the time patients feel sick. Having more treatment options that work in different ways to attack the virus is important because flu viruses can become resistant to antiviral drugs,” Debra Birnkrant, MD, director of the Division of Antiviral Products in the FDA’s Center for Drug Evaluation and Research, said in a press release.

The most common adverse events associated with Xofluza were diarrhea and bronchitis.

“This is the first new antiviral flu treatment with a novel mechanism of action approved by the FDA in nearly 20 years,” FDA Commissioner Scott Gottlieb, MD, added. “With thousands of people getting the flu every year, and many people becoming seriously ill, having safe and effective treatment alternatives is critical. This novel drug provides an important, additional treatment option.”

san francisco – A new tuberculosis vaccine showed promise in a phase 2b trial, including efficacy in adults and subjects who were already exposed to TB. The vaccine showed efficacy in young adults – an important finding because models suggest that inducing immunity in adolescents and young adults would be the fastest and most cost-effective approach to dealing with the global TB epidemic.

CDC/Janice Carr

The study recruited adults who had previously been exposed to Mycobacterium tuberculosis, a population that receives no benefit from the long-standing bacillus Calmette-Guérin (BCG) vaccine. The overall efficacy of protection was 54%. “There isn’t any vaccine that’s been demonstrated to work in people who are already infected. It’s also the first vaccine to show this level of statistically significant protection in adults, and it’s adults who are the major transmitters of tuberculosis. The modeling has shown that even a vaccine that could protect infected adults at 20% vaccine efficacy would have a substantial impact on the epidemic and be cost effective,” said Ann Ginsberg, MD, PhD, chief medical officer at Aeras, which developed the vaccine and is now testing it in partnership with GlaxoSmithKline.

The results of the study were presented at ID Week 2018 and published in the New England Journal of Medicine (2018 Sep 25. doi: 10.1056/NEJMoa1803484).

The results address a major weakness of the BCG vaccine, which is that some studies have shown it offers little benefit to subjects who are already infected with the disease, which is the case for about a quarter of the world’s population, according to Dr. Ginsberg. The probable explanation is that previous infection with M. tuberculosis or a related bacteria is common in some populations and that this exposure grants some protection against progression to active disease.

The researchers tested the M72/AS01E vaccine, which includes two M. tuberculosis antigens that were identified from patients who had controlled their infection and also the AS01 adjuvant, which contains two immunostimulating agents and is a component of a developmental malaria vaccine and the recombinant zoster vaccine Shingrix.

In Kenya, South Africa, and Zambia, the researchers randomized 3,330 participants (mean age, 28.9 years; 43% female) to receive two doses 1 month apart of either vaccine or placebo. After a mean follow-up of 2.3 years, the protocol efficacy analysis showed that the vaccine had an efficacy rate of 54.0% (P = .04) for pulmonary tuberculosis.

The vaccine had greater efficacy in men (75.2%; P = .03) than it did in women (27.4%; P = .52) and among individuals aged 25 years or younger (84.4%; P = .01) than it did among older subjects (10.2%, P = .82).

The frequency of serious adverse events was similar between the vaccine (1.6%) and the placebo group (1.8%). Unsolicited reports of adverse events were more common in the vaccine group than the placebo group (67.4% vs. 45.4%, respectively), driven largely by more reports of injection site reactions and flu-like symptoms. Solicited reports of adverse events were highlighted by a greater frequency of injection site pain in the vaccine group (81.8% vs. 34.4%). A total of 24.3% of the vaccine recipients reported grade 3 pain, compared with 3.3% in the placebo arm. Rates of fatigue, headache, malaise, or myalgia were also higher in the vaccine group, as was fever.

All of the subjects in the vaccine group had seroconversion at month 2, and 99% remained seroconverted at 12 months.

Next, the researchers plan to conduct studies in HIV-infected individuals and to proceed with phase III trials.

The trial was funded by GlaxoSmithKline Biologicals and Aeras. Dr. Ginsberg is an employee of Aeras.

Psoriasis patients are more vulnerable to systemic infections, including influenza-related pneumonia, but a new study shows that they are less likely to receive the influenza vaccine than patients with RA.

Jovanmandic/Thinkstock

Vaccination rates were higher in psoriasis patients aged over 50 years, those who were female, and those with other chronic medical conditions, however.

Megan H. Noe, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, and her coauthors referred to recent evidence suggesting that psoriasis involves systemic inflammation that increase the risk of comorbidities and that hospitalization rates for serious infections, including lower respiratory tract infections and pneumonia, are higher among adults with psoriasis than those who do not have psoriasis.

To compare influenza vaccination rates in psoriasis patients with those among patients with other chronic diseases, they conducted a cohort study, drawing from administrative and commercial claims data from OptumInsight Clinformatics Data Mart. They examined all adult patients with psoriasis, RA, or chronic hypertension who required oral antihypertensive medication. The study population included individuals tracked during the 2010-2011 flu season and 24 months prior (September 2008 to March 2011). This year was chosen because it was labeled as a “typical” season by the Centers for Disease Control and Prevention.

The primary outcome was a claim for an influenza vaccine, and covariates included age, length of residency, gender, and a clinical history of a range of conditions known to be associated with greater risk of influenza complications.

The population included 17,078 patients with psoriasis, 21,832 with RA, and 496,972 with chronic hypertension. After controlling for sex and age, the probability of getting a flu vaccine was similar between psoriasis and hypertension patients, but RA patients were more likely to be vaccinated than patients with psoriasis (odds ratio, 1.08; 95% confidence interval, 1.03-1.13). But the likelihood varied with age: 30-year-old patients with RA were more likely than a 30-year-old psoriasis patient to get a flu shot (OR, 1.30; 95% CI, 1.18-1.45), while a 70-year-old patient with RA was about as likely to get the flu vaccine as a 70-year-old patient with psoriasis.

Female psoriasis patients were more likely to get a flu shot than males (OR, 1.29; 95% CI, 1.20-1.38). Among the psoriasis patients, having some medical comorbidities were linked to a greater likelihood of being vaccinated, including asthma (OR, 1.58; 95% CI, 1.40-1.77), chronic liver disease (OR, 1.23; 95%, 1.03-1.47), diabetes (OR, 1.48; 95% CI, 1.36-1.63), HIV (OR, 3.68; 95% CI, 2.06-6.57), history of malignancy (OR, 1.21; 95% CI, 1.09-1.34), and psoriatic arthritis (OR, 1.40; 95% CI, 1.25-1.58).

There was no association between the use of an oral systemic therapy or biologic treatment and vaccination rates.

The authors suggested that psoriasis patients, especially younger ones, may not get adequate counseling on the value of the flu vaccine from their physicians. Studies have shown that, among the American public, health care providers are the most influential source of information about the flu vaccine. Among younger patients, the dermatologist may be a psoriasis patient’s primary health care provider, so it is important for dermatologists to counsel patients about the recommended vaccines, the authors wrote.

“Further research understanding why adults with psoriasis do not receive recommended vaccinations will help to create targeted interventions to improve vaccination rates and decrease hospitalizations in adults with psoriasis,” they concluded.

The study relied on administrative claims, so the results may not be generalizable to patients with insurance types other than those in the database or who are uninsured, the authors noted.

This study was funded by the National Psoriasis Foundation, the Dermatology Foundation, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Noe and three other authors did not report any disclosures, the fifth author reported multiple disclosures related to various pharmaceutical companies.

SAN FRANCISCO – An adjuvanted trivalent flu vaccine cuts the risk of hospitalizations in nursing home residents by about 6%, according to a new study presented at an annual scientific meeting on infectious diseases.

“It’s one thing to say you have a more immunogenic vaccine, it’s another thing to be able to say it offers clinical benefit, especially in the oldest old and the frailest frail,” says Stefan Gravenstein, MD, professor of medicine and health services, policy and practice at the Brown University School of Public Health, Providence, R.I. Dr. Gravenstein presented a poster outlying a randomized, clinical trial of the Fluad vaccine in nursing homes.

The study randomized the nursing homes so that some facilities would offer Fluad as part of their standard of care. The design helped address the problem of consent. Any clinical trial that requires individual consent would likely exclude many of the frailest patients, leading to an unrepresentative sample. “So if you want to have a generalizable result, you’d like to have it applied to the population the way you would in the real world, so randomizing the nursing homes rather than the people makes a lot of sense,” said Dr. Gravenstein.

Dr. Gravenstein chose to test the vaccine in nursing home residents, hoping to see a signal in a population in which flu complications are more common. “If you can get a difference in a nursing home population, that’s clinically important, that gives you hope that you can see it in all the other populations, too,” he said.

SAN FRANCISCO – Influenza season is upon us, and Helen Chu, MD, MPH, is here at ID Week 2018 to talk vaccines, especially for pregnant women.

They are at greater risk for more severe illness, and influenza can lead to adverse outcomes in infants. The good news is that recent studies have shown that flu vaccines are safe and effective in pregnant women.

The bad news is that many women are hesitant to be vaccinated out of concerns over safety, in a trend that reflects broader societal worries over vaccination, said Dr. Chu, of the University of Washington, Seattle. In a video interview at an annual scientific meeting on infectious diseases, Dr. Chu advised steps to ensure that pregnant women are aware of the safety and efficacy of flu vaccines, and the benefits to the infant who acquires immunity through the mother. It’s also a good idea to have vaccine on hand to be able to offer it immediately during an office visit.

ATLANTA – The 13-valent pneumococcal conjugate vaccine (PCV13) shows moderate overall effectiveness for preventing invasive pneumococcal disease (IPD) caused by PCV13 vaccine serotypes in adults aged 65 years and older, according to a case-control study involving Medicare beneficiaries.

Conversely, the 23-valent pneumococcal polysaccharide vaccine (PPSV23) showed limited effectiveness against serotypes unique to that vaccine in the study, which included 699 cases and more than 10,000 controls, Olivia Almendares, an epidemiologist at the Centers for Disease Control and Prevention, Atlanta, and her colleagues reported in a poster at the International Conference on Emerging Infectious Diseases.

“Vaccine efficacy against PCV13 [plus 6C type, which has cross-reactivity with serotype 6A] was 47% in those who received PCV13 vaccine only,” Ms. Almendares said in an interview, noting that efficacy was 26% against serotype 3 and 67% against other PCV13 serotypes (plus 6C). “Vaccine efficacy against PPSV23-unique types was 36% for those who received only PPSV23.”

Neither vaccine showed effectiveness against serotypes not included in the respective vaccines, she said.

The findings are timely given that the Advisory Committee on Immunization Practices (ACIP) is reevaluating its PCV13 recommendation for adults aged 65 years and older, she added.

“Specifically, ACIP is addressing whether PCV13 should be recommended routinely for all immunocompetent adults aged 65 and older given sustained indirect effects,” she said, explaining that, in 2014 when ACIP recommended routine use of the vaccine in series with PPSV23 for adults aged 65 years and older, the committee recognized that herd immunity effects from PCV13 use in children might eventually limit the utility of this recommendation, and therefore it proposed reevaluation and revision as needed after 4 years.

For the current study, she and her colleagues linked IPD cases in persons aged 65 years and older, which were identified through Active Bacterial Core surveillance during 2015-2016, to records for Centers for Medicare & Medicaid Services (CMS) beneficiaries. Vaccination and medical histories were obtained through medical records, and vaccine effectiveness was estimated as one minus the odds ratio for vaccination with PCV13 only or PPSV23 only versus neither vaccine using conditional logistic regression, with adjustment for sex and underlying medical conditions.

Of 2,246 IPD cases, 1,017 (45%) were matched to Medicare beneficiaries, and 699 were included in the analysis after those with noncontinuous enrollment in Medicare, long-term care residence, and missing census tract data were excluded. The cases were matched based on age, census tract of residence, and length of Medicare enrollment to 10,152 matched controls identified through CMS.

IPD associated with PCV13 (plus type 6C) accounted for 164 (23% of cases), of which 88 (12% of cases) involved serotype 3, and invasive pneumococcal disease associated with PPSV23 accounted for 350 cases (50%), she said.

PCV13 vaccine was given alone in 14% and 18% of cases and controls, respectively; PPSV23 alone was given in 22% and 21% of case patients and controls, respectively; and both vaccines were given in 8% of cases and controls.

Compared with controls, case patients were more likely to be of nonwhite race (16% vs. 11%), to have more than one chronic medical condition (88% vs. 58%), and to have one or more immunocompromising conditions (54% vs. 32%), she and her colleagues reported.

“PCV13 showed moderate overall effectiveness in preventing IPD caused by PCV13 (including 6C), but effectiveness may be lower for serotype 3 than for other PCV13 types,” she said.

“These results are in agreement with those from CAPiTA – a large clinical trial conducted in the Netherlands, which showed PCV13 to be effective against IPD caused by vaccine serotypes among community-dwelling adults aged 65 and older,” she noted. “Additionally, data from CDC surveillance suggest that PCV13-serotype [invasive pneumococcal disease] among children and adults aged 65 and older has declined dramatically following PCV13 introduction for children in 2010, as predicted.”

In fact, among adults aged 65 years and older, PCV13-serotype invasive pneumococcal disease declined by 40% after the vaccine was introduced in children. This corresponds to a change in the annual PCV13-serotype incidence from 14 cases per 100,000 population in 2010 to five cases per 100,000 population in 2014, she said; she added that IPD incidence plateaued in 2014-2016 with vaccine serotypes contributing to a small proportion of overall IPD burden among adults aged 65 years and older.

ACIP’s reevaluation of the PCV13 recommendation is ongoing and will be addressed at upcoming meetings.

“As part of the review process, we look at changes in disease incidence focusing primarily on invasive pneumococcal disease and noninvasive pneumonia, vaccine efficacy and effectiveness, and vaccine safety,” she said. She noted that ACIP currently has no plans to consider revising PCV13 recommendations for adults who have immunocompromising conditions, for whom PCV13 has been recommended since 2012.

PARIS – Using a point-of-care test for viral pathogens, hospital admissions were avoided in about a third of emergency department patients with suspected respiratory infection when other clinical signs also suggested a low risk of a bacterial pathogen, according to a single-center experience presented at the annual congress of the European Respiratory Society.

“We found that when patients had point-of-care respiratory viral testing soon after they were admitted to the emergency department, we were able to reduce unnecessary admission and improve bed flow in our center,” reported Kay Roy, MBBS, consultant physician in respiratory medicine, West Hertfordshire (England) Hospital NHS Trust.

In a protocol that was launched at Dr. Kay’s institution in January 2018, the point-of-care viral test was combined with other clinical factors, particularly chest x-rays and elevated C-reactive protein (CRP), to determine whether patients had a viral pathogen and whether they could be discharged without antibiotics.

“Clinical judgment will always be required in individual patient decisions regarding antibiotic avoidance and early discharge,” Dr. Roy maintained. “But the point-of-care viral assay can be integrated into a strategy that permits more informed and rapid decision-making.”

This assertion is supported by the experience using a protocol anchored with the point-of-care viral test over a 4-month period. During this time, 901 patients with respiratory symptoms suspected of having a viral etiology were evaluated with the proprietary point-of-care device called FilmArray (bioMérieux).

From a sample taken with a nasopharyngeal swab, the test can identify a broad array of viruses using polymerase chain reaction technology in less than 45 minutes. However, the ED protocol for considering discharge without antibiotics requires additional evidence that the pathogen is viral, including a normal chest x-ray and a CRP less than 50 mg/L.

Of the 901 patients tested, a substantial proportion of whom had chronic obstructive pulmonary disease (COPD) or asthma, 507 (56%) tested positive for at least one virus, including influenza, rhinoviruses, coronaviruses, and adenovirus. Of these, 239 had normal chest x-rays and CRPs less than 50 mg/L. Because of the severity of symptoms or other clinical considerations, 154 patients were admitted, but 85 (36% of those meeting protocol criteria) were discharged without an antibiotic prescription.

“Antibiotics were continued in 90% of the patients who had an abnormal chest x-ray and abnormal CRP,” Dr. Roy reported. However, an objective strategy that permits clinicians to discharge patients at very low risk of a bacterial infection has many advantages even if it applies to a relatively modest proportion of those tested, according to Dr. Roy.

“Each respiratory admission can cost around [2,000 pounds] at our center,” reported Dr. Kay, referring to a figure equivalent to more than $2,600. In addition, she said that avoiding hospitalization frees up hospital beds and facilitates improved antimicrobial stewardship, which is vital to stem resistance.

Avoiding antibiotic use in patients with viral respiratory infections also is relevant to improved antibiotic stewardship in the community. For this reason, a randomized trial with a similar protocol involving the point-of-care viral test is planned in the outpatient setting. According to Dr. Roy, this will involve a community hub to which patients can be referred for testing and clinical evaluation.

“We hope that the quality of care can be improved with the point-of-care test for respiratory viruses as well as helping to reduce antibiotic resistance,” Dr. Roy said.

This approach is promising, according to Tobias Welte, MD, of the department of respiratory medicine at Hannover (Germany) Medical School, but he cautioned that it is not a standard approach.

“The protocol described by Dr. Roy will have to be compared to guidelines and recommended best clinical practice to confirm its usefulness,” he said, while conceding that any strategy that reduces unnecessary hospitalizations deserves further evaluation.

Most in-hospital deaths from community-acquired pneumonia are not preventable with current medical therapy, according to an analysis of deaths at five U.S. hospitals with expertise in pneumonia care.

Adults who are hospitalized with community-acquired pneumonia (CAP) are at high risk for short-term mortality but it is unclear whether an improvement in care could lower this risk, noted the study authors led by Grant W. Waterer, MBBS, PhD, of Northwestern University, Chicago.

“Understanding the circumstances in which CAP patients die could facilitate improvements in the management of CAP by enabling future improvement efforts to focus on common preventable causes of death,” they wrote. Their report was published in CHEST^®.

They therefore performed a secondary analysis of the Etiology of Pneumonia in the Community (EPIC) study involving adults hospitalized with CAP between January 2010 and June 2012 across five tertiary-care hospitals in the United States.

The clinical characteristics of patients who died in the hospital were compared with those of patients who survived to hospital discharge. Chronic heart failure, chronic obstructive pulmonary disease, coronary artery disease, chronic liver disease, cerebrovascular disease, cancer (excluding skin cancer), and diabetes were considered as severe chronic comorbidities based on their association with increased mortality and ICU admission in CAP severity scores.

Deaths caused by septic shock, respiratory failure, multisystem organ failure, cardiopulmonary arrest prior to stabilization of CAP, and endocarditis, were considered to be directly related to CAP.

Conversely, causes of death indirectly related to CAP included acute cardiovascular disease, stroke, acute renal failure, and secondary infections developed after hospitalization. Deaths caused by cancer, cirrhosis, and chronic neurologic conditions were considered unrelated to CAP.

Medical notes were assessed to determine whether the patient received management consistent with current recommendations; for example, antibiotics consistent with guidelines from the Infectious Diseases Society of America.

End-of-life limitations in care, such as patient/family decision not to proceed with full medical treatment, also were considered by the research team.

Results showed that among the 2,320 patients with radiographically confirmed CAP, 52 died during initial hospitalization, 33 of whom were aged 65 years or older, and 32 of whom had two or more chronic comorbidities.

Most of the in-hospital deaths occurred early in the hospitalization: 35 within the first 10 days of admission, and 5 after 30 days in hospital.

CAP was judged by an expert physician review panel to be the direct cause of death in 27 of the patients, 10 with CAP having an indirect role with major contribution, 9 with CAP having an indirect role with minor contribution, and 6 with CAP having no role in death.

Do-not-resuscitate orders were present at the time of death for 21 of the patients.

Forty-five of the patients were admitted to an ICU, with 37 dying in the ICU. The eight patients who died on the ward after transfer out of the ICU had end-of-life limitations of care in place.

The researchers noted that the number of patients dying in the ICU was greater in the United States, possibly because in Europe fewer patients are admitted to an ICU.

“This discrepancy likely reflects cultural differences between the U.S. and Europe in the role of intensive care for patients with advanced age and/or advanced comorbid conditions,” they noted.

Overall, the physician review panel identified nine patients who had a lapse in quality of in-hospital CAP care, with four of the deaths potentially linked to this lapse in care.

However, two of the patients had end-of-life limitations of care in place, which according to the authors meant that “only two patients undergoing full medical treatment without end-of-life limitations of care had an identified lapse in quality of in-hospital pneumonia care potentially contributing to in-hospital death, including one with a delay in antibiotics for over an hour in the presence of shock and one with initial antibiotics not consistent with IDSA/ATS guidelines.”

The research team concluded that most in-hospital deaths among adult patients admitted with CAP in their study would not have been preventable with higher quality in-hospital pneumonia care.

“Many of the in-hospital deaths among patients admitted with CAP occurred in older patients with severe comorbidities and end-of-life limitations in care,” they noted.

They said the influence of end-of-life limitations on care short of full palliation was an important finding, with all patients who died outside the ICU having end-of-life limitations in care.

“Current diagnostic related group (DRG) and international classification of diseases (ICD) coding systems do not have the necessary nuances to capture these limitations of care, yet they are clearly important factors in determining whether patients experience in-hospital death,” they added.

Dr. Waterer reported no conflicts. Two coauthors reported potential conflicts of interest in relation to consulting fees from several pharmaceutical companies.

Adults who are hospitalized with community-acquired pneumonia (CAP) are at high risk for short-term mortality but it is unclear whether an improvement in care could lower this risk, noted the study authors led by Grant W. Waterer, MBBS, PhD, of Northwestern University, Chicago.

“Understanding the circumstances in which CAP patients die could facilitate improvements in the management of CAP by enabling future improvement efforts to focus on common preventable causes of death,” they wrote. Their report was published in CHEST^®.

They therefore performed a secondary analysis of the Etiology of Pneumonia in the Community (EPIC) study involving adults hospitalized with CAP between January 2010 and June 2012 across five tertiary-care hospitals in the United States.

The clinical characteristics of patients who died in the hospital were compared with those of patients who survived to hospital discharge. Chronic heart failure, chronic obstructive pulmonary disease, coronary artery disease, chronic liver disease, cerebrovascular disease, cancer (excluding skin cancer), and diabetes were considered as severe chronic comorbidities based on their association with increased mortality and ICU admission in CAP severity scores.

Deaths caused by septic shock, respiratory failure, multisystem organ failure, cardiopulmonary arrest prior to stabilization of CAP, and endocarditis, were considered to be directly related to CAP.

Conversely, causes of death indirectly related to CAP included acute cardiovascular disease, stroke, acute renal failure, and secondary infections developed after hospitalization. Deaths caused by cancer, cirrhosis, and chronic neurologic conditions were considered unrelated to CAP.

Medical notes were assessed to determine whether the patient received management consistent with current recommendations; for example, antibiotics consistent with guidelines from the Infectious Diseases Society of America.

End-of-life limitations in care, such as patient/family decision not to proceed with full medical treatment, also were considered by the research team.

Results showed that among the 2,320 patients with radiographically confirmed CAP, 52 died during initial hospitalization, 33 of whom were aged 65 years or older, and 32 of whom had two or more chronic comorbidities.

Most of the in-hospital deaths occurred early in the hospitalization: 35 within the first 10 days of admission, and 5 after 30 days in hospital.

CAP was judged by an expert physician review panel to be the direct cause of death in 27 of the patients, 10 with CAP having an indirect role with major contribution, 9 with CAP having an indirect role with minor contribution, and 6 with CAP having no role in death.

Do-not-resuscitate orders were present at the time of death for 21 of the patients.

Forty-five of the patients were admitted to an ICU, with 37 dying in the ICU. The eight patients who died on the ward after transfer out of the ICU had end-of-life limitations of care in place.

The researchers noted that the number of patients dying in the ICU was greater in the United States, possibly because in Europe fewer patients are admitted to an ICU.

“This discrepancy likely reflects cultural differences between the U.S. and Europe in the role of intensive care for patients with advanced age and/or advanced comorbid conditions,” they noted.

Overall, the physician review panel identified nine patients who had a lapse in quality of in-hospital CAP care, with four of the deaths potentially linked to this lapse in care.

A concerted international effort is planned to eradicate tuberculosis, a lethal disease affecting one-quarter of the world’s population by the year 2030.

On September 26 the United Nations General Assembly will convene a high-level meeting of global stakeholders to solidify the eradication plan, addressing the global crisis of tuberculosis (TB), the world’s most deadly infectious disease.

“We must seize the moment,” said Tereza Kasaeva, MD, director of the World Health Organization’s global TB program, speaking at a telebriefing and press conference accompanying the release of the World Health Organization’s annual global tuberculosis report. “It’s unacceptable in the 21st century that millions lose their lives to this preventable and curable disease.”

TB caused 1.6 million deaths globally in 2017, and the World Health Organization (WHO) estimates that of the 10 million new cases of TB last year, 558,000 are multi-drug resistant (MDR) infections.

Though death rates and new cases are falling globally each year, significantly more resources are needed to boost access to preventive treatment for latent TB infection; “Most people needing it are not yet accessing care,” according to the press briefing accompanying the report.

A review and commentary on TB incubation and latency published in BMJ (2018;362:k2738 doi: 10.1136/bmj.k2738; e-pub 23 Aug 2018) has called into question the focus preventive treatment of latent cases at the expense of reaching those most likely to die from TB (e.g., HIV patients, children of individuals living with active TB). The authors state that “latent” TB  is identified by indirect evidence of present or past infection with Mycobacterium tuberculosis as inferred by a detectable adaptive immune response to M tuberculosis antigens. Active TB infection is overwhelmingly the result of a primary infection and almost always occurs within two years.

In order to meet the ambitious goal of TB eradication by the year 2030, treatment coverage must rise to 90% globally from the current 64%, according to the report.

Progress in southern Africa and in the Russian Federation, where efforts have led to a 30% reduction in TB mortality and a decrease in incidence of 5% per year, show that steep reductions in TB are possible when resources are brought to bear on the problem, said Dr. Kasaeva. “We should acknowledge that actions in some countries and regions show that progress can accelerate,” she said. Still, she noted, “Four thousand lives per day are lost to TB. Tuberculosis is the leading killer of people living with HIV, and the major cause of deaths related to antimicrobial resistance” at a global level.

Two thirds of all TB cases occur in eight countries, with India, China, and Indonesia leading this group. About half of the cases of MDR TB occur in India, China, and Russia, said Dr. Kasaeva, and globally only one in four individuals with MDR TB who need access to treatment have received it. “We need to urgently tackle the multidrug resistant TB public health crisis,” she said.

Major impediments to successful public health efforts against TB are underdiagnosis and underreporting: It is estimated that 3.6 million of 2017’s 10 million new cases were not officially recorded or reported. Countries where these problems are most serious include India, Indonesia, and Nigeria. Fewer than half of the children with TB are reported globally, according to the report.

People living with HIV/AIDS who are also infected with TB number nearly 1,000,000, but only about half of these were officially reported in 2017.

In terms of prevention priorities, WHO has recommended targeting treatment of latent TB in two groups: People living with HIV/AIDS, and children under the age of 5 years who live in households with TB-infected individuals.

“To enable these actions,” said Dr. Kasaeva, “we need strengthened commitments not just for TB care, but for overall health services. So the aim for universal coverage is real.” Underreporting is particularly prevalent in lower income countries with large unregulated private sectors, she said, though India and Indonesia have taken corrective steps to increase reporting.

A meaningful global initiative will not come cheap: The current annual shortfall in funding for TB prevention, diagnosis, and treatment is about $3.5 billion. By the year 2022, the gap between funding and what’s needed to stay on track for the 2030 target will be over $6 billion, said Dr. Kasaeva.

The best use of increased resources for TB eradication will be in locally focused efforts, said Irene Koek, MD, the United States Agency for International Development’s deputy administrator for global health. “It is likely that each region requires a tailored response.” Further, “to improve quality of care we need to ensure that services are patient centered,” she said at the press conference.

To that end, Dr. Koek expects that at the upcoming high-level meeting, the United Nations member states will be called on to develop an open framework, with clear accountability for monitoring and reviewing progress. The road forward should “celebrate accomplishments and acknowledge shortcomings,” she said. Some recent studies have shown that treatment success rates above 80% for patients with MDR TB can be achieved.

“Lessons learned from these experiences should be documented and shared in order to replicate success globally,” said Dr. Koek.

The United States, said Dr. Koek, is the leading global investor in TB research and treatment. “We welcome increased partnerships, especially with countries with the highest burden, to end global suffering from this disease.”

Eric Goosby, MD, the United Nations special envoy on TB, used his speaking time to lend some perspective to the social framework around TB’s longtime lethality.

There are aspects of TB infection that differentiate it from HIV/AIDS, said Dr. Goosby, who has spent most of his clinical and public health career on HIV/AIDS treatment and prevention. In contrast to an infection that at present requires a lifetime of treatment, TB can ordinarily be treated in 6 months, making it an unpleasant episode that an individual may be eager to move past. Additionally, the fact that TB has had a “hold on the world since the time of the ancient Egyptians” may paradoxically have served to lessen urgency in research and treatment efforts, he noted.

Dr. Goosby also spoke of the stigma surrounding TB, whose sufferers are likely to be facing dire poverty, malnutrition, and other infectious disease burdens. Civil society concerned with TB, he said, has spoken up “for those without a voice, for those who have difficulty advocating for themselves.”

Dr. Kasaeva agreed, noting that TB “affects the poorest of the poor, which makes it extraordinarily difficult for activism to come from that population.”

However, others have spoken for those affected, said Dr. Goosby. “The TB civil society has put its heart and soul this last year into gathering political will from leaders around the world…. It’s not a passive effort; it involves a lot of work.” During the past year of concerted effort, he said, “All of us have known the difficulty of pushing a political leader up that learning curve.”

As the upcoming high-level meeting approaches, those who have been working on the effort can feel the momentum, said Dr. Goosby. Still, he noted, “While there’s a significant step forward, this is not the time for a victory dance. This is really the time for a reflection...Do we understand the burden in our respective countries, and has the response been adequate?”

The goal for the meeting is to have leaders “step up to commit, not for one day, or for one meeting, but for the duration of the effort,” said Dr. Goosby. “We must make sure that the words that we hear next week from our leaders translate into action...Next week the world will say, ‘No more. No longer. No one is immune to TB. Tuberculosis is preventable; tuberculosis is treatable; tuberculosis is curable.’”

The BMJ commentary, by Marcel A. Behr, MD, of McGill International TB Centre, Infectious Diseases and Immunity in Global Health Program, McGill University Health Centre Research Institute, and his colleagues, recommend caution when building a prevention strategy around treating many millions of individuals with “latent” TB. They wrote, “Immunoreactivity to TB does not necessarily indicate the presence of live bacteria, as reactivity can persist after infection has been cleared. Classifying two billion people with evidence of immunoreactivity as having latent TB infection may divert fundamental research and public health interventions away from transmissible active TB disease and newly infected people at highest risk of progression to disease.”

Still, he noted, “While there’s a significant step forward, this is not the time for a victory dance. This is really the time for a reflection...Do we understand the burden in our respective countries, and has the response been adequate?”

The goal for the meeting is to have leaders “step up to commit, not for one day, or for one meeting, but for the duration of the effort,” said Dr. Goosby. “We must make sure that the words that we hear next week from our leaders translate into action...Next week the world will say, ‘No more. No longer. No one is immune to TB. Tuberculosis is preventable; tuberculosis is treatable; tuberculosis is curable.’”

The BMJ commentary, by Marcel A. Behr, MD, of McGill International TB Centre, Infectious Diseases and Immunity in Global Health Program, McGill University Health Centre Research Institute, and his colleagues, recommend caution when building a prevention strategy around treating many millions of individuals with “latent” TB. They wrote, “Immunoreactivity to TB does not necessarily indicate the presence of live bacteria, as reactivity can persist after infection has been cleared. Classifying two billion people with evidence of immunoreactivity as having latent TB infection may divert fundamental research and public health interventions away from transmissible active TB disease and newly infected people at highest risk of progression to disease.”
