Pediatric bronchiolitis: Less is more

A common cause of infant morbidity and hospitalization in developed countries, infant viral bronchiolitis, has long been bedeviled by treatment uncertainty beyond supportive care.

Dr. Matthew J. Lipshaw

Rationales for most pharmacologic treatments continue to be debated, and clinical practice guidelines generally advise respiratory and hydration support, discouraging the use of chest radiography, albuterol, glucocorticoids, antibiotics, and epinephrine.

Despite evidence that the latter interventions are ineffective, they are still too often applied, according to two recent studies, one in Pediatrics, the other in JAMA Pediatrics.

“The pull of the therapeutic vacuum surrounding this disease has been noted in the pages of this journal for at least 50 years, with Wright and Beem writing in 1965 that ‘energies should not be frittered away by the annoyance of unnecessary or futile medications and procedures’ for the child with bronchiolitis,” said emergency physicians Matthew J. Lipshaw, MD, MS, of the Cincinnati Children’s Hospital Medical Center, and Todd A. Florin, MD, MSCE, of Ann and Robert H. Lurie Children’s Hospital of Chicago.

These remarks came in their editorial in Pediatrics wryly titled: “Don’t Just Do Something, Stand There” and published online to accompany a recent study of three network meta-analyses.

Led by Sarah A. Elliott, PhD, of the Alberta Research Centre for Health Evidence at the University of Alberta in Edmonton, this analysis amalgamated 150 randomized, controlled trials comparing a placebo or active comparator with any bronchodilator, glucocorticoid steroid, hypertonic saline solution, antibiotic, helium-oxygen therapy, or high-flow oxygen therapy. It then looked at the following outcomes in children aged 2 years and younger: hospital admission rate on day 1, hospital admission rate within 7 days, and total hospital length of stay.

Few treatments seemed more effective than nebulized placebo (0.9% saline) for short-term outcomes, the authors found. While nebulized epinephrine and nebulized hypertonic saline plus salbutamol appeared to reduce admission rates during the index ED presentation, and hypertonic saline, alone or in combination with epinephrine, seemed to reduce hospital stays, such treatment had no effect on admissions within 7 days of initial presentation. Furthermore, most benefits disappeared in higher-quality studies.

Concluding, albeit with weak evidence and low confidence, that some benefit might accrue with hypertonic saline with salbutamol to reduce admission rates on initial presentation to the ED, the authors called for well-designed studies on treatments in inpatients and outpatients.

According to Dr. Lipshaw, assistant professor of clinical pediatrics, the lack of benefit observed in superior studies limits the applicability of Dr. Elliott and colleagues’ results to immediate clinical practice. “These findings could be used, however, to target future high-quality studies toward the medications that they found might be useful,” he said in an interview.

For the present, other recent research augurs well for strategically reducing unnecessary care. In a paper published online in JAMA Pediatrics, Libby Haskell, MN, of the ED at Starship Children’s Hospital in Auckland, New Zealand, and associates reported on a cluster-randomized, controlled trial of targeted interventions.

Conducted in 2017 at 26 hospitals and with 3,727 babies in New Zealand and Australia, the study addressed drivers of non–evidence-based approaches with behavior-modifying approaches such as on-site clinical leads, stakeholder meetings, a train-the-trainer workshop, education, and audit and feedback.

The authors reported a 14.1% difference in rates of compliance during the first 24 hours of hospitalization favoring the intervention group for all five bronchiolitis guideline recommendations. The greatest change was seen in albuterol and chest radiography use, with other improvements in ED visits, inpatient consultations, and throughout hospitalization.

“These results provide clinicians and hospitals with clear implementation strategies to address unnecessary treatment of infants with bronchiolitis,” Dr. Haskell’s group wrote. Dr. Lipshaw agreed that multifaceted deimplementation packages including clinician and family education, audit and feedback, and clinical decision support have been successful. “Haskell et al. demonstrated that it is possible to successfully deimplement non–evidence-based practices for bronchiolitis with targeted inventions,” he said. “It would be wonderful to see their success replicated in the U.S.”


 

 

 

Why the slow adoption of guidelines?

The American Academy of Pediatrics issued bronchiolitis guidelines for babies to 23 months in 2014 and updated them in 2018. Why, then, has care in some centers been seemingly all over the map and counter to guidelines? “Both parents and clinicians are acting in what they believe to be the best interests of the child, and in the absence of high-value interventions, can feel the need to do something, even if that something is not supported by evidence,” Dr. Lipshaw said. 

Furthermore, with children in obvious distress, breathing fast and with difficulty, and sometimes unable to eat or drink, “we feel like we should have some way to make them feel better quicker. Unfortunately, none of the medications we have tried seem to be useful for most children, and we are left with supportive care measures such as suctioning their noses, giving them oxygen if their oxygen is low, and giving them fluids if they are dehydrated.”

Dr. Diana S. Lee

Other physicians agree that taking a less-is-more approach can be challenging and even counterintuitive. “To families, seeing their child’s doctor ‘doing less’ can be frustrating,” admitted Diana S. Lee, MD, assistant professor of pediatrics at Icahn School of Medicine at Mount Sinai, New York.

Beyond that, altering practice behavior will need more than guidelines, Dr. Lee said in an interview. “Haskell et al. showed targeted behavior-change interventions improved compliance with bronchiolitis guidelines, but such change requires motivation and resources, and the sustainability of this effect over time remains to be seen.”

At Dr. Lipshaw’s institution, treatment depends on the attending physician, “but we have an emergency department care algorithm, which does not recommend any inhaled medications or steroids in accordance with the 2014 AAP guidelines,” he said.

Similarly at Mount Sinai, practitioners strive to follow the AAP guidelines, although their implementation has not been immediate, Dr. Lee said. “This is a situation where we must make the effort to choose not to do more, given current evidence.”

Dr. Michelle R. Dunn

But Michelle Dunn, MD, an attending physician in the division of general pediatrics at the Children’s Hospital of Philadelphia, said the American practice norm already tends more to the observance than the breach of the guidelines, noting that since 2014 quality improvement efforts have been made throughout the country. “At our institution, we have effectively reduced the use of albuterol in patients with bronchiolitis and we use evidence-based therapy as much as possible, which in the case of bronchiolitis generally involves supportive management alone,” she said in an interview.

Still, Dr. Dunn added, many patients receive unnecessary diagnostic testing and ineffective therapies, with some providers facing psychological barriers to doing less. “However, with more and more evidence to support this, hopefully, physicians will become more comfortable with this.”

To that end, Dr. Lipshaw’s editorial urges physicians to “curb the rampant use of therapies repeatedly revealed to be ineffective,” citing team engagement, clear practice guidelines, and information technology as key factors in deimplementation. In the meantime, his mantra remains: “Don’t just do something, stand there.”

The study by Dr. Elliot and colleagues was supported by the Canadian Institutes of Health Research Knowledge Synthesis grant program. One coauthor is supported by a University of Ottawa Tier I Research Chair in Pediatric Emergency Medicine. Another is supported by a Tier 1 Canada Research Chair in Knowledge Synthesis and Translation and the Stollery Science Laboratory. Dr. Lipshaw and Dr. Florin disclosed no financial relationships relevant to their commentary. Dr. Haskell and colleagues were supported, variously, by the National Health and Medical Research Council of New Zealand, the Center of Research Excellence for Pediatric Emergency Medicine, the Victorian Government’s Operational Infrastructure Support Program, Cure Kids New Zealand, the Royal Children’s Hospital Foundation, and the Starship Foundation. Dr. Lee and Dr. Dunn had no competing interests to disclose with regard to their comments.

Hospitalization not rare for children with COVID, study says

About 12% of U.S. children who presented to an emergency department or received inpatient care for COVID-19 in a hospital network and were included in the Premier Healthcare Database Special COVID-19 Release were hospitalized in 2020. Nearly a third of those had severe disease that required mechanical ventilation or admission to an intensive care unit, according to a new study published in JAMA Network Open on April 9.*

That means about 1 in 9 kids with COVID-19 in this cohort needed hospitalization, and about 1 in 28 had severe COVID-19.

“Although most children with COVID-19 experience mild illness, some children develop serious illness that leads to hospitalization, use of invasive mechanical ventilation, and death,” the researchers wrote.

The research team analyzed discharge data from 869 medical facilities in the Premier Healthcare Database Special COVID-19 Release. They looked for COVID-19 patients ages 18 and under who had an in-patient or emergency department visit between March and October 2020.

More than 20,700 children with COVID-19 had an in-patient or an emergency department visit, and 2,430 were hospitalized with COVID-19. Among those, 756 children had severe COVID-19 and were admitted to an intensive care unit or needed mechanical ventilation.

About 53% of the COVID-19 patients were girls, and about 54% were between ages 12-18. In addition, about 29% had at least one chronic condition.

Similar to COVID-19 studies in adults, Hispanic, Latino and Black patients were overrepresented. About 39% of the children were Hispanic or Latino, and 24% were Black. However, the researchers didn’t find an association between severe COVID-19 and race or ethnicity.

The likelihood of severe COVID-19 increased if the patient had at least one chronic condition, was male, or was between ages 2-11.

“Understanding factors associated with severe COVID-19 disease among children could help inform prevention and control strategies,” they added. “Reducing infection risk through community mitigation strategies is critical for protecting children from COVID-19 and preventing poor outcomes.”

As of April 8, more than 3.54 million U.S. children have tested positive for COVID-19, according to the latest report from the American Academy of Pediatrics and Children’s Hospital Association. Cases among children are increasing slightly, with about 73,000 new cases reported during the first week of April.

Children represent about 13.5% of the COVID-19 cases in the country, according to the report. Among the 24 states that provide data, children represented 1% to 3% of all COVID-19 hospitalizations, and less than 2% of all child COVID-19 cases resulted in hospitalization.

“At this time, it appears that severe illness due to COVID-19 is rare among children,” the two groups wrote.

“However, there is an urgent need to collect more data on longer-term impacts of the pandemic on children, including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects,” they added.

*CORRECTION, 6/7/21 – This story has been corrected to clarify that the patient sample study reflects only those children who presented to an emergency department or received inpatient care for COVID-19 in a hospital network and were included in the Premier Healthcare Database Special COVID-19 Release.

A previous version of the story incorrectly implied that 12% of all U.S. children with COVID-19 had required inpatient care.

Prospective data support delaying antibiotics for pediatric respiratory infections

For pediatric patients with respiratory tract infections (RTIs), immediately prescribing antibiotics may do more harm than good, based on prospective data from 436 children treated by primary care pediatricians in Spain.

Dr. Feghaly

In the largest trial of its kind to date, children who were immediately prescribed antibiotics showed no significant difference in symptom severity or duration from those who received a delayed prescription for antibiotics, or no prescription at all; yet those in the immediate-prescription group had a higher rate of gastrointestinal adverse events, reported lead author Gemma Mas-Dalmau, MD, of the Sant Pau Institute for Biomedical Research, Barcelona, and colleagues.

“Most RTIs are self-limiting, and antibiotics hardly alter the course of the condition, yet antibiotics are frequently prescribed for these conditions,” the investigators wrote in Pediatrics. “Antibiotic prescription for RTIs in children is especially considered to be inappropriately high.”

This clinical behavior is driven by several factors, according to Dr. Mas-Dalmau and colleagues, including limited diagnostics in primary care, pressure to meet parental expectations, and concern for possible complications if antibiotics are withheld or delayed.

In an accompanying editorial, Jeffrey S. Gerber, MD, PhD and Bonnie F. Offit, MD, of Children’s Hospital of Philadelphia, noted that “children in the United States receive more than one antibiotic prescription per year, driven largely by acute RTIs.”

Dr. Gerber and Dr. Offit noted that some RTIs are indeed caused by bacteria, and therefore benefit from antibiotics, but it’s “not always easy” to identify these cases.

“Primary care, urgent care, and emergency medicine clinicians have a hard job,” they wrote.

According to the Centers for Disease Control and Prevention, delayed prescription of antibiotics, in which a prescription is filled upon persistence or worsening of symptoms, can balance clinical caution and antibiotic stewardship.

“An example of this approach is acute otitis media, in which delayed prescribing has been shown to safely reduce antibiotic exposure,” wrote Dr. Gerber and Dr. Offit.

In a 2017 Cochrane systematic review of both adults and children with RTIs, antibiotic prescriptions, whether immediate, delayed, or not given at all, had no significant effect on most symptoms or complications. Although several randomized trials have evaluated delayed antibiotic prescriptions in children, Dr. Mas-Dalmau and colleagues described the current body of evidence as “scant.”

The present study built upon this knowledge base by prospectively following 436 children treated at 39 primary care centers in Spain from 2012 to 2016. Patients were between 2 and 14 years of age and presented for rhinosinusitis, pharyngitis, acute otitis media, or acute bronchitis. Inclusion in the study required the pediatrician to have “reasonable doubts about the need to prescribe an antibiotic.” Clinics with access to rapid streptococcal testing did not enroll patients with pharyngitis.

Patients were randomized in approximately equal groups to receive either immediate prescription of antibiotics, delayed prescription, or no prescription. In the delayed group, caregivers were advised to fill prescriptions if any of following three events occurred:

  • No symptom improvement after a certain amount of days, depending on presenting complaint (acute otitis media, 4 days; pharyngitis, 7 days; acute rhinosinusitis, 15 days; acute bronchitis, 20 days).
  • Temperature of at least 39° C after 24 hours, or at least 38° C but less than 39° C after 48 hours.
  • Patient feeling “much worse.”
 

 

Primary outcomes were severity and duration of symptoms over 30 days, while secondary outcomes included antibiotic use over 30 days, additional unscheduled visits to primary care over 30 days, and parental satisfaction and beliefs regarding antibiotic efficacy.

In the final dataset, 148 patients received immediate antibiotic prescriptions, while 146 received delayed prescriptions, and 142 received no prescription. Rate of antibiotic use was highest in the immediate prescription group, at 96%, versus 25.3% in the delayed group and 12% among those who received no prescription upon first presentation (P < .001).

Although the mean duration of severe symptoms was longest in the delayed-prescription group, at 12.4 days, versus 10.9 days in the no-prescription group and 10.1 days in the immediate-prescription group, these differences were not statistically significant (P = .539). Median score for greatest severity of any symptom was also similar across groups. Secondary outcomes echoed this pattern, in which reconsultation rates and caregiver satisfaction were statistically similar regardless of treatment type.

In contrast, patients who received immediate antibiotic prescriptions had a significantly higher rate of gastrointestinal adverse events (8.8%) than those who received a delayed prescription (3.4%) or no prescription (2.8%; P = .037).

“Delayed antibiotic prescription is an efficacious and safe strategy for reducing inappropriate antibiotic treatment of uncomplicated RTIs in children when the doctor has reasonable doubts regarding the indication,” the investigators concluded. “[It] is therefore a useful tool for addressing the public health issue of bacterial resistance. However, no antibiotic prescription remains the recommended strategy when it is clear that antibiotics are not indicated, like in most cases of acute bronchitis.”

“These data are reassuring,” wrote Dr. Gerber and Dr. Offit; however, they went on to suggest that the data “might not substantially move the needle.”

“With rare exceptions, children with acute pharyngitis should first receive a group A streptococcal test,” they wrote. “If results are positive, all patients should get antibiotics; if results are negative, no one gets them. Acute bronchitis (whatever that is in children) is viral. Acute sinusitis with persistent symptoms (the most commonly diagnosed variety) already has a delayed option, and the current study ... was not powered for this outcome. We are left with acute otitis media, which dominated enrollment but already has an evidence-based guideline.”

Still, Dr. Gerber and Dr. Offit suggested that the findings should further encourage pediatricians to prescribe antibiotics judiciously, and when elected, to choose the shortest duration and narrowest spectrum possible.

Dr. Jackson

In a joint comment, Rana El Feghaly, MD, MSCI, director of outpatient antibiotic stewardship at Children’s Mercy, Kansas City, and her colleague, Mary Anne Jackson, MD, noted that the findings are “in accordance” with the 2017 Cochrane review.

Dr. Feghaly and Dr. Jackson said that these new data provide greater support for conservative use of antibiotics, which is badly needed, considering approximately 50% of outpatient prescriptions are unnecessary or inappropriate .

Delayed antibiotic prescription is part of a multifaceted approach to the issue, they said, joining “communication skills training, antibiotic justification documentation, audit and feedback reporting with peer comparison, diagnostic stewardship, [and] the use of clinician education on practice-based guidelines.”

“Leveraging delayed antibiotic prescription may be an excellent way to combat antibiotic overuse in the outpatient setting, while avoiding provider and parental fear of the ‘no antibiotic’ approach,” Dr. Feghaly and Dr. Jackson said.

Karlyn Kinsella, MD, of Pediatric Associates of Cheshire, Conn., suggested that clinicians discuss these findings with parents who request antibiotics for “otitis, pharyngitis, bronchitis, or sinusitis.”

“We can cite this study that antibiotics have no effect on symptom duration or severity for these illnesses,” Dr. Kinsella said. “Of course, our clinical opinion in each case takes precedent.”

According to Dr. Kinsella, conversations with parents also need to cover reasonable expectations, as the study did, with clear time frames for each condition in which children should start to get better.

“I think this is really key in our anticipatory guidance so that patients know what to expect,” she said.

The study was funded by Instituto de Salud Carlos III, the European Union, and the Spanish Ministry of Health, Social Services, and Equality. The investigators and interviewees reported no conflicts of interest.

Arthritis drugs ‘impressive’ for severe COVID but not ‘magic cure’

Article Type
Changed
Thu, 08/26/2021 - 15:52

New findings suggest that monoclonal antibodies used to treat RA could improve severe COVID-19 outcomes, including risk for death.

Given within 24 hours of critical illness, tocilizumab (Actemra) was associated with a median of 10 days free of respiratory and cardiovascular support up to day 21, the primary outcome. Similarly, sarilumab (Kevzara) was linked to a median of 11 days. In contrast, the usual care control group experienced zero such days in the hospital.

However, the Randomized, Embedded, Multifactorial Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP) trial comes with a caveat. The preprint findings have not yet been peer reviewed and “should not be used to guide clinical practice,” the authors stated.

The results were published online Jan. 7 in MedRxiv.

Nevertheless, the trial also revealed a mortality benefit associated with the two interleukin-6 antagonists. The hospital mortality rate was 22% with sarilumab, 28% with tocilizumab, and almost 36% with usual care.

“That’s a big change in survival. They are both lifesaving drugs,” lead coinvestigator Anthony Gordon, an Imperial College London professor of anesthesia and critical care, commented in a recent  story by Reuters.
 

Consider the big picture

“What I think is important is ... this is one of many trials,” Paul Auwaerter, MD, MBA, said in an interview. Many other studies looking at monoclonal antibody therapy for people with COVID-19 were halted because they did not show improvement.

Dr. Paul Auwaerter

One exception is the EMPACTA trial, which suggested that tocilizumab was effective if given before a person becomes ill enough to be placed on a ventilator, said Dr. Auwaerter, clinical director of the division of infectious diseases at Johns Hopkins Medicine and a contributor to this news organization. “It appeared to reduce the need for mechanical ventilation or death.”

“These two trials are the first randomized, prospective trials that show a benefit on a background of others which have not,” Dr. Auwaerter added.
 

Interim findings

The REMAP-CAP investigators randomly assigned adults within 24 hours of critical care for COVID-19 to 8 mg/kg tocilizumab, 400 mg sarilumab, or usual care at 113 sites in six countries. There were 353 participants in the tocilizumab arm, 48 in the sarilumab group, and 402 in the control group.

Compared with the control group, the 10 days free of organ support in the tocilizumab cohort was associated with an adjusted odds ratio of 1.64 (95% confidence interval, 1.25-2.14). The 11 days free of organ support in the sarilumab cohort was likewise superior to control (adjusted odds ratio, 1.76; 95% CI, 1.17-2.91).

“All secondary outcomes and analyses supported efficacy of these IL-6 receptor antagonists,” the authors note. These endpoints included 90-day survival, time to intensive care unit discharge, and hospital discharge.
 

Cautious optimism?

“The results were quite impressive – having 10 or 11 fewer days in the ICU, compared to standard of care,” Deepa Gotur, MD, said in an interview. “Choosing the right patient population and providing the anti-IL-6 treatment at the right time would be the key here.”

Dr. Deepa Gotur

In addition to not yet receiving peer review, an open-label design, a relatively short follow-up of 21 days, and steroids becoming standard of care about halfway through the trial are potential limitations, said Dr. Gotur, an intensivist at Houston Methodist Hospital and associate professor of clinical medicine at Weill Cornell Medicine, New York.

“This is an interesting study,” Carl J. Fichtenbaum, MD, professor of clinical medicine at the University of Cincinnati, said in a comment.

Additional detail on how many participants in each group received steroids is warranted, Dr. Fichtenbaum said. “The analysis did not carefully adjust for the use of steroids that might have influenced outcomes.”

Dr. Carl J. Fichtenbaum

Dr. Fichtenbaum said it’s important to look at what is distinctive about REMAP-CAP because “there are several other studies showing opposite results.”

Dr. Gotur was an investigator on a previous study evaluating tocilizumab for patients already on mechanical ventilation. “One of the key differences between this and other studies is that they included more of the ICU population,” she said. “They also included patients within 24 hours of requiring organ support, cardiac, as well as respiratory support.” Some other research included less-acute patients, including all comers into the ED who required oxygen and received tocilizumab.

The prior studies also evaluated cytokine or inflammatory markers. In contrast, REMAP-CAP researchers “looked at organ failure itself ... which I think makes sense,” Dr. Gotur said.

Cytokine release syndrome can cause organ damage or organ failure, she added, “but these markers are all over the place. I’ve seen patients who are very, very sick despite having a low [C-reactive protein] or IL-6 level.”
 

Backing from the British

Citing the combined 24% decrease in the risk for death associated with these agents in the REMAP-CAP trial, the U.K. government announced Jan. 7 it will work to make tocilizumab and sarilumab available to citizens with severe COVID-19.

Experts in the United Kingdom shared their perspectives on the REMAP-CAP interim findings through the U.K. Science Media Centre.

“There are few treatments for severe COVID-19,” said Robin Ferner, MD, honorary professor of clinical pharmacology at the University of Birmingham (England) and honorary consultant physician at City Hospital Birmingham. “If the published data from REMAP-CAP are supported by further studies, this suggests that two IL-6 receptor antagonists can reduce the death rate in the most severely ill patients.”

Dr. Ferner added that the findings are not a “magic cure,” however. He pointed out that of 401 patients given the drugs, 109 died, and with standard treatment, 144 out of 402 died.

Peter Horby, MD, PhD, was more optimistic. “It is great to see a positive result at a time that we really need good news and more tools to fight COVID. This is great achievement for REMAP-CAP,” he said.



“We hope to soon have results from RECOVERY on the effect of tocilizumab in less severely ill patients in the hospital,” said Dr. Horby, cochief investigator of the RECOVERY trial and professor of emerging infectious diseases at the Centre for Tropical Medicine and Global Health at the University of Oxford (England).

Stephen Evans, BA, MSc, FRCP, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said, “This is a high-quality trial, and although published as a preprint, is of much higher quality than many non–peer-reviewed papers.”

Dr. Evans also noted the addition of steroid therapy for many participants. “Partway through the trial, the RECOVERY trial findings showed that the corticosteroid drug dexamethasone had notable mortality benefits. Consequently, quite a number of the patients in this trial had also received a corticosteroid.”

“It does look as though these drugs give some additional benefit beyond that given by dexamethasone,” he added.

 

 

Awaiting peer review

“We need to wait for the final results and ensure it was adequately powered with enough observations to make us confident in the results,” Dr. Fichtenbaum said.

“We in the United States have to step back and look at the entire set of studies and also, for this particular one, REMAP-CAP, to be in a peer-reviewed publication,” Dr. Auwaerter said. Preprints are often released “in the setting of the pandemic, where there may be important findings, especially if they impact mortality or severity of illness.”

“We need to make sure these findings, as outlined, hold up,” he said.

In the meantime, Dr. Auwaerter added, “Exactly how this will fit in is unclear. But it’s important to me as another potential drug that can help our critically ill patients.”

The REMAP-CAP study is ongoing and updated results will be provided online.

Dr. Auwaerter disclosed that he is a consultant for EMD Serono and a member of the data monitoring safety board for Humanigen. Dr. Gotur, Dr. Fichtenbaum, Dr. Ferner, and Dr. Evans disclosed no relevant financial relationships. Dr. Horby reported that Oxford University receives funding for the RECOVERY trial from U.K. Research and Innovation and the National Institute for Health Research. Roche Products and Sanofi supported REMAP-CAP through provision of tocilizumab and sarilumab in the United Kingdom.

One exception is the EMPACTA trial, which suggested that tocilizumab was effective if given before a person becomes ill enough to be placed on a ventilator, said Dr. Auwaerter, clinical director of the division of infectious diseases at Johns Hopkins Medicine and a contributor to this news organization. “It appeared to reduce the need for mechanical ventilation or death.”

“These two trials are the first randomized, prospective trials that show a benefit on a background of others which have not,” Dr. Auwaerter added.
 

Interim findings

The REMAP-CAP investigators randomly assigned adults within 24 hours of critical care for COVID-19 to 8 mg/kg tocilizumab, 400 mg sarilumab, or usual care at 113 sites in six countries. There were 353 participants in the tocilizumab arm, 48 in the sarilumab group, and 402 in the control group.

Compared with the control group, the 10 days free of organ support in the tocilizumab cohort was associated with an adjusted odds ratio of 1.64 (95% confidence interval, 1.25-2.14). The 11 days free of organ support in the sarilumab cohort was likewise superior to control (adjusted odds ratio, 1.76; 95% CI, 1.17-2.91).

“All secondary outcomes and analyses supported efficacy of these IL-6 receptor antagonists,” the authors note. These endpoints included 90-day survival, time to intensive care unit discharge, and hospital discharge.
 

Cautious optimism?

“The results were quite impressive – having 10 or 11 fewer days in the ICU, compared to standard of care,” Deepa Gotur, MD, said in an interview. “Choosing the right patient population and providing the anti-IL-6 treatment at the right time would be the key here.”

In addition to not yet receiving peer review, an open-label design, a relatively short follow-up of 21 days, and steroids becoming standard of care about halfway through the trial are potential limitations, said Dr. Gotur, an intensivist at Houston Methodist Hospital and associate professor of clinical medicine at Weill Cornell Medicine, New York.

“This is an interesting study,” Carl J. Fichtenbaum, MD, professor of clinical medicine at the University of Cincinnati, said in a comment.

Additional detail on how many participants in each group received steroids is warranted, Dr. Fichtenbaum said. “The analysis did not carefully adjust for the use of steroids that might have influenced outcomes.”

Dr. Carl J. Fichtenbaum

Dr. Fichtenbaum said it’s important to look at what is distinctive about REMAP-CAP because “there are several other studies showing opposite results.”

Dr. Gotur was an investigator on a previous study evaluating tocilizumab for patients already on mechanical ventilation. “One of the key differences between this and other studies is that they included more of the ICU population,” she said. “They also included patients within 24 hours of requiring organ support, cardiac, as well as respiratory support.” Some other research included less-acute patients, including all comers into the ED who required oxygen and received tocilizumab.

The prior studies also evaluated cytokine or inflammatory markers. In contrast, REMAP-CAP researchers “looked at organ failure itself ... which I think makes sense,” Dr. Gotur said.

Cytokine release syndrome can cause organ damage or organ failure, she added, “but these markers are all over the place. I’ve seen patients who are very, very sick despite having a low [C-reactive protein] or IL-6 level.”
 

Backing from the British

Citing the combined 24% decrease in the risk for death associated with these agents in the REMAP-CAP trial, the U.K. government announced Jan. 7 it will work to make tocilizumab and sarilumab available to citizens with severe COVID-19.

Experts in the United Kingdom shared their perspectives on the REMAP-CAP interim findings through the U.K. Science Media Centre.

“There are few treatments for severe COVID-19,” said Robin Ferner, MD, honorary professor of clinical pharmacology at the University of Birmingham (England) and honorary consultant physician at City Hospital Birmingham. “If the published data from REMAP-CAP are supported by further studies, this suggests that two IL-6 receptor antagonists can reduce the death rate in the most severely ill patients.”

Dr. Ferner added that the findings are not a “magic cure,” however. He pointed out that of 401 patients given the drugs, 109 died, and with standard treatment, 144 out of 402 died.

Peter Horby, MD, PhD, was more optimistic. “It is great to see a positive result at a time that we really need good news and more tools to fight COVID. This is great achievement for REMAP-CAP,” he said.



“We hope to soon have results from RECOVERY on the effect of tocilizumab in less severely ill patients in the hospital,” said Dr. Horby, cochief investigator of the RECOVERY trial and professor of emerging infectious diseases at the Centre for Tropical Medicine and Global Health at the University of Oxford (England).

Stephen Evans, BA, MSc, FRCP, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said, “This is a high-quality trial, and although published as a preprint, is of much higher quality than many non–peer-reviewed papers.”

Dr. Evans also noted the addition of steroid therapy for many participants. “Partway through the trial, the RECOVERY trial findings showed that the corticosteroid drug dexamethasone had notable mortality benefits. Consequently, quite a number of the patients in this trial had also received a corticosteroid.”

“It does look as though these drugs give some additional benefit beyond that given by dexamethasone,” he added.

 

 

Awaiting peer review

“We need to wait for the final results and ensure it was adequately powered with enough observations to make us confident in the results,” Dr. Fichtenbaum said.

“We in the United States have to step back and look at the entire set of studies and also, for this particular one, REMAP-CAP, to be in a peer-reviewed publication,” Dr. Auwaerter said. Preprints are often released “in the setting of the pandemic, where there may be important findings, especially if they impact mortality or severity of illness.”

“We need to make sure these findings, as outlined, hold up,” he said.

In the meantime, Dr. Auwaerter added, “Exactly how this will fit in is unclear. But it’s important to me as another potential drug that can help our critically ill patients.”

The REMAP-CAP study is ongoing and updated results will be provided online.

Dr. Auwaerter disclosed that he is a consultant for EMD Serono and a member of the data monitoring safety board for Humanigen. Dr. Gotur, Dr. Fichtenbaum, Dr. Ferner, and Dr. Evans disclosed no relevant financial relationships. Dr. Horby reported that Oxford University receives funding for the RECOVERY trial from U.K. Research and Innovation and the National Institute for Health Research. Roche Products and Sanofi supported REMAP-CAP through provision of tocilizumab and sarilumab in the United Kingdom.

New findings suggest that monoclonal antibodies used to treat RA could improve severe COVID-19 outcomes, including risk for death.

Given within 24 hours of critical illness, tocilizumab (Actemra) was associated with a median of 10 days free of respiratory and cardiovascular support up to day 21, the primary outcome. Similarly, sarilumab (Kevzara) was linked to a median of 11 days. In contrast, the usual care control group experienced zero such days in the hospital.

However, the Randomized, Embedded, Multifactorial Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP) trial comes with a caveat. The preprint findings have not yet been peer reviewed and “should not be used to guide clinical practice,” the authors stated.

The results were published online Jan. 7 in MedRxiv.

Nevertheless, the trial also revealed a mortality benefit associated with the two interleukin-6 antagonists. The hospital mortality rate was 22% with sarilumab, 28% with tocilizumab, and almost 36% with usual care.

“That’s a big change in survival. They are both lifesaving drugs,” lead coinvestigator Anthony Gordon, an Imperial College London professor of anesthesia and critical care, commented in a recent  story by Reuters.
 

Consider the big picture

COVID-19 symptoms persist months after acute infection

Article Type
Changed
Thu, 08/26/2021 - 15:52

Three-quarters of patients hospitalized with COVID-19 were still experiencing at least one symptom of the infection 6 months after being discharged, according to a follow-up study involving 1,733 patients.

“Patients with COVID-19 had symptoms of fatigue or muscle weakness, sleep difficulties, and anxiety or depression,” and those with “more severe illness during their hospital stay had increasingly impaired pulmonary diffusion capacities and abnormal chest imaging manifestations,” Chaolin Huang, MD, of Jin Yin-tan Hospital in Wuhan, China, and associates wrote in the Lancet.

Fatigue or muscle weakness, reported by 63% of patients, was the most common symptom, followed by sleep difficulties, hair loss, and smell disorder. Altogether, 76% of those examined 6 months after discharge from Jin Yin-tan hospital – the first designated for patients with COVID-19 in Wuhan – reported at least one symptom, they said.

Symptoms were more common in women than men: 81% vs. 73% had at least one symptom, and 66% vs. 59% had fatigue or muscle weakness. Women were also more likely than men to report anxiety or depression at follow-up: 28% vs. 18% (23% overall), the investigators said.



Patients with the most severe COVID-19 were 2.4 times as likely to report any symptom later, compared with those who had the least severe levels of infection. Among the 349 participants who completed a lung function test at follow-up, lung diffusion impairment was seen in 56% of those with the most severe illness and 22% of those with the lowest level, Dr. Huang and associates reported.

In a different subset of 94 patients from whom plasma samples were collected, the “seropositivity and median titres of the neutralising antibodies were significantly lower than at the acute phase,” raising concern for reinfection, they said.

The results of the study, the investigators noted, “support that those with severe disease need post-discharge care. Longer follow-up studies in a larger population are necessary to understand the full spectrum of health consequences from COVID-19.”

Seeking new vaccines against whooping cough: The PERISCOPE project

Article Type
Changed
Tue, 01/05/2021 - 11:17

Although there is an effective vaccine against Bordetella pertussis, whooping cough remains a leading cause of death. Cases are increasing, and scientists face challenges in developing new vaccines.

In a key research session at the start of the annual meeting of the European Society for Paediatric Infectious Diseases, held virtually this year, Dimitri Diavatopoulos, PhD, associate professor at the Radboud University Medical Centre Nijmegen, the Netherlands, summarized the pertussis vaccination problem and what the Pertussis Correlates of Protection Europe (PERISCOPE) project seeks to achieve. Dr. Diavatopoulos has a longstanding interest in pertussis and immunity and will soon take over as the scientific coordinator of PERISCOPE.

Pertussis is a highly contagious infectious disease that causes uncontrollable coughing. The disease begins with an atypical cough and rhinorrhea before entering a paroxysmal stage characterized by cyanosis, lymphocytosis, vomiting, and whoops. Generally, fever is absent and coughing increases at night. Finally, after weeks to months, the patient enters a convalescent stage. The World Health Organization estimates that there are 16 million pertussis cases annually and approximately 195,000 deaths in children. Most cases are caused by Bordetella pertussis and are preventable by vaccination.

In the United States, following the introduction of a national immunization program using a whole-cell vaccine in the 1950s, cases fell significantly. After a lag phase, the adoption of an acellular vaccine in the United States in 1997 and the Netherlands in 2005 – usually in combination with diphtheria and tetanus via DTaP – saw an increase in case numbers. Dr. Diavatopoulos stated that control is no longer as good, compared with other infectious diseases prevented by the MMR vaccine, such as mumps, measles, and rubella.

In the face of increasing numbers, how do we move to the next generation of vaccines to improve control? There are several barriers to licensure, including the following:

• Universal recommendation for pertussis prevention means that more than 90% of the population will have received DTaP (usually in combination with polio and Haemophilus influenzae B) and be protected for several years after vaccination.

• Because DTaP vaccines are only efficacious for a limited time, the problem is not immediately apparent.

• Pertussis epidemics are cyclical, occurring every 3-5 years. These peaks and troughs complicate the development of epidemiological studies.

What this means is that large-scale Phase III efficacy studies, in which disease is used as the endpoint, are not feasible. Also, formal correlates of protection have not been identified.

The PERISCOPE Project started in March 2016 and is designed to respond to some of these issues. Funding is made available by a public private consortium involving the Bill & Melinda Gates foundation, the European Union, and European Federation of Pharmaceutical Industries and Associations (EFPIA) partners, and in this case, GlaxoSmithKline and Sanofi Pasteur. In total, there are 22 partners in this project.

The strategic objectives of this partnership include the following:

• Foster expertise and increase capacity in Europe to evaluate new pertussis vaccines both in clinical and preclinical models.

• Identify early biomarkers of long-lasting protective immunity to pertussis in humans. (This step will accelerate and de-risk clinical development of next generation pertussis vaccines.)

• Investigate the impact of maternal vaccination on infant response to pertussis vaccination.

The problem is that there is no one single study design that addresses all questions about the pertussis vaccine. For example, in PERISCOPE, the results of preclinical studies using the baboon or mouse models and addressing disease and colonization endpoints or immunogenicity do not perfectly model human infection and disease.

By comparison, controlled human infection studies provide information on colonization but not disease endpoints. Such studies, however, do provide information on immunogenicity endpoints. Also available are booster vaccination studies and infant vaccination studies providing data on immunogenicity, as well as safety information.

Finally, there are patient studies, such as household contact studies where immunogenicity can be correlated to disease endpoints. From these studies, it will be seen that what is needed is integration of evidence from clinical and preclinical studies to support a new vaccine registration.

PERISCOPE addresses these issues by developing novel, functional antibody and cellular assays and employing cutting-edge methods to characterize innate immune responses and cell-mediated systemic and mucosal immunity. PERISCOPE combines two major industrial partners with public researchers from academic and public health institutes and small and medium-sized enterprises with expertise in clinical trials, vaccinology, immunology, molecular microbiology, challenge models, and bioinformatics.

Andrew Gorringe, PhD, from Public Health England and the Research and Development Institute at Porton Down, Wiltshire, England, said, “Vaccines have greatly reduced the incidence of pertussis, but it remains the most prevalent ‘vaccine preventable’ disease. This is an exciting period for pertussis vaccine research as we find new ways to understand the immunity that protects from both infection and disease. The PERISCOPE project provides a collaborative environment that combines expertise across Europe to provide a route to the development of new, more effective vaccines.”

GSK and Sanofi Pasteur have cofunded the PERISCOPE Project. Dr. Diavatopoulos made no other financial disclosures.

After a lag phase, the adoption of an acellular vaccine in the United States in 1997 and the Netherlands in 2005 – usually in combination with diphtheria and tetanus via DTaP – saw an increase in case numbers. Dr. Diavatopoulos stated that control is no longer as good, compared with other infectious diseases prevented by the MMR vaccine, such as mumps, measles, and rubella.

In the face of increasing numbers, how do we move to the next generation of vaccines to improve control? There are several barriers to licensure, including the following:

• Universal recommendation for pertussis prevention means that more than 90% of the population will have received DTaP (usually in combination with polio and Haemophilus influenzae B) and be protected for several years after vaccination.

• Because DTaP vaccines are only efficacious for a limited time, the problem is not immediately apparent.

• Pertussis epidemics are cyclical, occurring every 3-5 years. These peaks and troughs complicate the development of epidemiological studies.

What this means is that large-scale Phase III efficacy studies, in which disease is used as the endpoint, are not feasible. Also, formal correlates of protection have not been identified.

The PERISCOPE Project started in March 2016 and is designed to respond to some of these issues. Funding is made available by a public private consortium involving the Bill & Melinda Gates foundation, the European Union, and European Federation of Pharmaceutical Industries and Associations (EFPIA) partners, and in this case, GlaxoSmithKline and Sanofi Pasteur. In total, there are 22 partners in this project.

The strategic objectives of this partnership include the following:

• Foster expertise and increase capacity in Europe to evaluate new pertussis vaccines both in clinical and preclinical models.

• Identify early biomarkers of long-lasting protective immunity to pertussis in humans. (This step will accelerate and de-risk clinical development of next generation pertussis vaccines.)

• Investigate the impact of maternal vaccination on infant response to pertussis vaccination.

The problem is that there is no one single study design that addresses all questions about the pertussis vaccine. For example, in PERISCOPE, the results of preclinical studies using the baboon or mouse models and addressing disease and colonization endpoints or immunogenicity do not perfectly model human infection and disease.

By comparison, controlled human infection studies provide information on colonization but not disease endpoints. Such studies, however, do provide information on immunogenicity endpoints. Also available are booster vaccination studies and infant vaccination studies providing data on immunogenicity, as well as safety information.

Finally, there are patient studies, such as household contact studies where immunogenicity can be correlated to disease endpoints. From these studies, it will be seen that what is needed is integration of evidence from clinical and preclinical studies to support a new vaccine registration.

PERISCOPE addresses these issues by developing novel, functional antibody and cellular assays and employing cutting-edge methods to characterize innate immune responses and cell-mediated systemic and mucosal immunity. PERISCOPE combines two major industrial partners with public researchers from academic and public health institutes and small and medium-sized enterprises with expertise in clinical trials, vaccinology, immunology, molecular microbiology, challenge models, and bioinformatics.

Andrew Gorringe, PhD, from Public Health England and the Research and Development Institute at Porton Down, Wiltshire, England, said, “Vaccines have greatly reduced the incidence of pertussis, but it remains the most prevalent ‘vaccine preventable’ disease. This is an exciting period for pertussis vaccine research as we find new ways to understand the immunity that protects from both infection and disease. The PERISCOPE project provides a collaborative environment that combines expertise across Europe to provide a route to the development of new, more effective vaccines.”

GSK and Sanofi Pasteur have cofunded the PERISCOPE Project. Dr. Diavatopoulos made no other financial disclosures.

Metapneumovirus infections clinically indistinguishable from flu, RSV

Article Type
Changed
Fri, 11/20/2020 - 10:00

 

The all-consuming news about SARS-CoV-2 and COVID-19 has overshadowed other viral pathogens that are the cause of severe or fatal lower respiratory infections (LRI) including human metapneumovirus (HMPV).

“MPV is really a leading cause of LRI not just in children but in adults, with high mortality rates in the frail elderly, long-term care facilities, and cancer patients with pneumonia, “ said John Williams, MD, from the department of pediatric infectious diseases at the University of Pittsburgh Medical Center.

“Right now we have no effective antivirals. There are monoclonal antibodies in development that my group and others have discovered. In fact, some of these treat MPV and RSV [respiratory syncytial virus], so we may have good options,” he said in an online presentation during an annual scientific meeting on infectious diseases.

The virus preys, wolf-like, on the most vulnerable patients, including children and frail elderly adults, as well as other adults with predisposing conditions, he said.

HMPV causes acute respiratory illnesses in approximately 2%-11% of hospitalized adults, 3%-25% of organ transplant recipients or cancer patients, 4%-12% of chronic obstructive pulmonary disease exacerbations, 5%-20% of asthma exacerbations, and it has been identified in multiple outbreaks at long-term care facilities.


 

Relative newcomer

Metapneumovirus was isolated and discovered from children with respiratory tract disease in the early 2000s. Once included in the family of paramyxoviruses (including measles, mumps, Nipah virus, and parainfluenza virus 1-4), HMPV and RSV are now classified as pneumoviruses, based on gene order and other characteristics, Dr. Williams explained.

Various studies have consistently placed the prevalence of HMPV ranging from 5%-14% in young children with LRI, children hospitalized for wheezing, adults with cancer and LRI, adults with asthma admissions, children with upper respiratory infections, and children hospitalized in the United States and Jordan for LRI, as well as children hospitalized in the United States and Peru with acute respiratory infections.

A study tracking respiratory infections in a Rochester, N.Y., cohort from 1999 through 2003 showed that healthy elderly patients had and annual incidence of HMPV infections of 5.9%, compared with 9.1% for high-risk patients, 13.1% for young patients, and 8.5% among hospitalized adult patients.

“These percentages are virtually identical to what has been seen in the same cohort for respiratory syncytial virus, so in this multiyear prospective cohort, metapneumovirus was as common as RSV,” Dr. Williams said.

Although the incidences of both HMPV and RSV were lower among hospitalized adults “clinically, we can’t tell these respiratory viruses apart. If we know it’s circulating we can make a guess, but we really can’t discriminate them,” he added.

In the Rochester cohort the frequency of clinical symptoms – including congestion, sore throat, cough, sputum production, dyspnea, and fever – were similar among patients infected with HMPV, RSV, or influenza A, with the exception of a slightly higher incidence of wheezing (80%) with HMPV, compared with influenza.

“I can tell you as a pediatrician, this is absolutely true in children, that metapneumovirus is indistinguishable from other respiratory viruses in kids,” he said.
 

Fatalities among older adults

As noted before, HMPV can cause severe and fatal illness in adults. For example, during an outbreak in North Dakota in 2016, 3 of 27 hospitalized adults with HMPV (median age, 69 years) died, and 10 required mechanical or noninvasive ventilation.

In a study from Korea comparing outcomes of severe HMPV-associated community-acquired pneumonia (CAP) with those of severe influenza-associated CAP, the investigators found that 30- and 60-day mortality rates were similar between the groups, at 24% of patients with HMPV-associated CAP and 32.1% for influenza-associated CAP, and 32% versus 38.5%, respectively.

Patients at high risk for severe disease or death from HMPV infection include those over 65 years, especially frail elderly, patients with chronic obstructive pulmonary disease, immunocompromised patients, and those with cardiopulmonary diseases such as congestive heart failure.
 

Supportive care only

“Do we have anything for treatment? The short answer is, No,” Dr. Williams.

Supportive care is currently the only effective approach for patients with severe HMPV infection.

Ribavirin, used to treat patients with acute RSV infection, has poor in vitro activity against HMPV and poor oral bioavailability and hemolysis, and there are no randomized controlled trials to support its use in this situation.

“It really can’t be recommended, and I don’t recommend it,” he said.
 

Virology may still help

Mark J. Siedner, MD, an infectious diseases physician at Mass General and associate professor of medicine at Harvard Medical School, both in Boston, who was not involved in the study, said that, despite the inability to clinically distinguish HMPV from RSV or influenza A, there is still clinical value to identifying HMPV infections.

“We spend millions of dollar each year treating people for upper respiratory tract infections, often with antibacterials, sometimes with antivirals, but those have costs to the health care system, and they also have costs in terms of drug resistance,” he said in an interview seeking objective commentary.

“Diagnostic tests that determine the actual source or the cause of these upper respiratory tract infections and encourage both patients and physicians not to be using antibiotics have value,” he said.

Identifying the pathogen can also help clinicians take appropriate infection-control precautions to prevent patient-to-clinician or patient-to-patient transmission of viral infections, he added.

Dr. Williams’ research is supported by the National Institutes of Health, Henry L. Hillman Foundation, and Asher Krop Memorial Fund of Children’s Hospital of Pittsburgh. Dr. Williams and Dr. Siedner reported no relevant conflict of interest disclosures.

Potentially practice-changing bacterial therapy trials analyzed

Article Type

Mon, 11/02/2020 - 08:38

 

A new formulation of an existing antibacterial agent and a potential therapeutic approach to a challenging clinical problem were the focus of a session on potentially practice-changing clinical trials in antimicrobial therapy presented during IDWeek 2020, an annual scientific meeting on infectious diseases.

“I know it has been a big year for viral disease of course, with COVID, but there has been some really good work that has gone on in the bacterial space, and of course as those of you who are on service know, you may have your fair share of COVID patients, but these are infections that we still deal with on a daily basis,” said Michael Satlin, MD, an infectious disease specialist at Weill Cornell Medicine in New York.

He combed through studies published during the previous 12 months in leading medical journals, including the New England Journal of Medicine, JAMA network publications, Lancet Infectious Diseases, Lancet Respiratory Medicine, Clinical Infectious Diseases, and Clinical Microbiology and Infection, looking for randomized trials of interventions to treat bacterial infections, and selecting those most likely to change practice of U.S. infectious diseases practitioners.

He excluded meta-analyses, post hoc analyses, evaluations of diagnostic tests, stewardship, or any studies presented previously at IDWeek.

Two of the trials he highlighted are described here.
 

Fosfomycin for injection

In the United States, fosfomycin, the only antibiotic in its class, is currently available only in an oral sachet formulation (Monurol), “and typically we’ve only given this for patients with cystitis because we know that we don’t achieve significant levels [of drug] in the kidney or in the bloodstream for other types of infections,” Dr. Satlin said.

In Europe, however fosfomycin for injection (ZTI-01) has been available for several years.

“There’s been a lot of interest in fosfomycin because it has a different mechanism of action from other agents. It’s an epoxide antibiotic that inhibits early peptidoglycan synthesis by binding to MurA,” he explained.

The phase 2/3 randomized ZEUS trial compared ZTI-01 with piperacillin/tazobactam (pip/taz) for treatment of complicated urinary tract infection (UTI) including acute pyelonephritis.

A total of 465 hospitalized adults with suspected or microbiologically confirmed complicated UTI or acute pyelonephritis were randomized to 6 g of ZTI-01 every 8 hours or 4.5 g of intravenous pip/taz every 8 hours for a fixed 7-day course with no oral switch; patients with concomitant bacteremia (about 9% of the study population) could receive the assigned therapy for up to 14 days.

The primary endpoint of noninferiority of ZTI-01 was met and clinical cure rates were high and similar between the treatments, at approximately 91% each. Treatment-emergent adverse events, including hypokalemia and elevated serum aminotransferases, were mostly mild and transient.

The hypokalemia seen in the trial may be attributable to the high salt load of fosfomycin relative to pip/taz, Dr. Satlin said.

“How might this change your practice? Well, if IV fosfomycin is ever FDA [Food and Drug Administration] approved – and my understanding is that the delays have been more related to manufacturing than scientific quality of data – it could potentially be an alternative to beta-lactams and fluoroquinolones” and has activity against most extend spectrum beta-lactamase (ESBL)–producing Enterobacteriaceae, he said.

Fosfomycin susceptibility testing is challenging, however, with no Clinical & Laboratory Standards Institute (CLSI) or FDA breakpoints for Enterobacterales other than Escherichia coli, and there are questions about the step-down therapy.

“Do you just give a 3-gram sachet chaser when they walk out the door? Do you switch to another agent? I think that needs to be worked out,” he said.
 

 

 

Inhaled amikacin

“We know that some IV antibiotics, particularly for resistant organisms, may not achieve sufficient concentrations in the lung to treat pneumonia. We know that inhaled antibiotics can give a lot of concentration of that drug right at the at the site of infection, but we don’t really have [randomized controlled trial] data to see whether it really helps,” Dr. Satlin said.

The INHALE trial was a double-blind, placebo-controlled superiority trial to see whether adding inhaled amikacin to IV standard-of-care antibiotics could improve outcomes for mechanically ventilated patients with gram-negative pneumonia.

The investigators enrolled 725 adults who were receiving mechanical ventilation for pneumonia, 45% of who had ventilator-associated pneumonia (VAP). Of the total cohort, 508 patients analyzed for efficacy had gram-negative pathogens, including 32% with Pseudomonas aeurginosa, 29% with Acinetobacter baumannii, 30% with E. coli, and the remainder with Klebsiella pneumoniae.

Patients were randomized to standard-of-care intravenous antibiotics plus either inhaled amikacin 400 mg twice daily for 10 days or inhaled saline placebo.

“Of note, the median standard-of-care antibiotics in this study was 18 days, which is certainly longer than what our guidelines recommend.”

There was no significant difference between study arms in the primary endpoint of survival at days 28-32 for all patients who had received at least one dose of study drug, were infected with a gram-negative pathogen, and an Acute Physiology and Chronic Health Evaluation (APACHE) II score of at 10 or higher at diagnosis. The respective survival rates for the inhaled amikacin and placebo groups were 75% and 77%. The incidence of treatment-emergent adverse events or serious treatment-emergent adverse events were similar between the two treatment arms.

“No matter how you sliced and diced it – days of mechanical ventilation, duration of ICU stay – essentially they looked the same. Even for [extensively drug resistant] pathogens where you might expect that you’d see the benefit of inhaled amikacin, they didn’t really see a mortality benefit in this study,” Dr. Satlin said.

The study is practice changing, he said “because I think inhaled aminoglycosides should not be routinely added to the standard of care IV antibiotics for pneumonia in ventilated patients,” he said.

It’s still unclear whether inhaled aminoglycosides might play a role in the treatment of select patients infected with organisms resistant to all beta-lactams and fluoroquinolones, he added.
 

Tempting strategy

“Adding inhaled antibiotics is a tempting strategy for treatment of ventilated pneumonia, which often has poor outcomes,” commented Thomas Holland, MD, a hospitalist and infectious disease specialist at Duke University Hospital in Durham, N.C. “This is valuable and practical information as clinicians choose antibiotics regimens for this difficult-to-treat syndrome,” he said in an interview.

Dr. Holland comoderated the session in which Dr. Satlin presented the study findings and opinions.

No funding source for the presentation was reported. Dr. Satlin reported consulting for Shionogi and Achaogen and research grants from Allergan, Merck, and BioFire Diagnostics. Dr. Holland disclosed consulting fees and other material support from Basilea Pharmaceutica, Genetech, Karius and Theravance.

The respective survival rates for the inhaled amikacin and placebo groups were 75% and 77%. The incidence of treatment-emergent adverse events or serious treatment-emergent adverse events were similar between the two treatment arms.

“No matter how you sliced and diced it – days of mechanical ventilation, duration of ICU stay – essentially they looked the same. Even for [extensively drug resistant] pathogens where you might expect that you’d see the benefit of inhaled amikacin, they didn’t really see a mortality benefit in this study,” Dr. Satlin said.

The study is practice changing, he said “because I think inhaled aminoglycosides should not be routinely added to the standard of care IV antibiotics for pneumonia in ventilated patients,” he said.

It’s still unclear whether inhaled aminoglycosides might play a role in the treatment of select patients infected with organisms resistant to all beta-lactams and fluoroquinolones, he added.
 

Tempting strategy

“Adding inhaled antibiotics is a tempting strategy for treatment of ventilated pneumonia, which often has poor outcomes,” commented Thomas Holland, MD, a hospitalist and infectious disease specialist at Duke University Hospital in Durham, N.C. “This is valuable and practical information as clinicians choose antibiotics regimens for this difficult-to-treat syndrome,” he said in an interview.

Dr. Holland comoderated the session in which Dr. Satlin presented the study findings and opinions.

No funding source for the presentation was reported. Dr. Satlin reported consulting for Shionogi and Achaogen and research grants from Allergan, Merck, and BioFire Diagnostics. Dr. Holland disclosed consulting fees and other material support from Basilea Pharmaceutica, Genetech, Karius and Theravance.

 

A new formulation of an existing antibacterial agent and a potential therapeutic approach to a challenging clinical problem were the focus of a session on potentially practice-changing clinical trials in antimicrobial therapy presented during IDWeek 2020, an annual scientific meeting on infectious diseases.

“I know it has been a big year for viral disease of course, with COVID, but there has been some really good work that has gone on in the bacterial space, and of course as those of you who are on service know, you may have your fair share of COVID patients, but these are infections that we still deal with on a daily basis,” said Michael Satlin, MD, an infectious disease specialist at Weill Cornell Medicine in New York.

He combed through studies published during the previous 12 months in leading medical journals, including the New England Journal of Medicine, JAMA network publications, Lancet Infectious Diseases, Lancet Respiratory Medicine, Clinical Infectious Diseases, and Clinical Microbiology and Infection, looking for randomized trials of interventions to treat bacterial infections, and selecting those most likely to change practice of U.S. infectious diseases practitioners.

He excluded meta-analyses, post hoc analyses, evaluations of diagnostic tests, stewardship, or any studies presented previously at IDWeek.

Two of the trials he highlighted are described here.
 

Fosfomycin for injection

In the United States, fosfomycin, the only antibiotic in its class, is currently available only in an oral sachet formulation (Monurol), “and typically we’ve only given this for patients with cystitis because we know that we don’t achieve significant levels [of drug] in the kidney or in the bloodstream for other types of infections,” Dr. Satlin said.

In Europe, however fosfomycin for injection (ZTI-01) has been available for several years.

“There’s been a lot of interest in fosfomycin because it has a different mechanism of action from other agents. It’s an epoxide antibiotic that inhibits early peptidoglycan synthesis by binding to MurA,” he explained.

The phase 2/3 randomized ZEUS trial compared ZTI-01 with piperacillin/tazobactam (pip/taz) for treatment of complicated urinary tract infection (UTI) including acute pyelonephritis.

A total of 465 hospitalized adults with suspected or microbiologically confirmed complicated UTI or acute pyelonephritis were randomized to 6 g of ZTI-01 every 8 hours or 4.5 g of intravenous pip/taz every 8 hours for a fixed 7-day course with no oral switch; patients with concomitant bacteremia (about 9% of the study population) could receive the assigned therapy for up to 14 days.

The primary endpoint of noninferiority of ZTI-01 was met and clinical cure rates were high and similar between the treatments, at approximately 91% each. Treatment-emergent adverse events, including hypokalemia and elevated serum aminotransferases, were mostly mild and transient.

The hypokalemia seen in the trial may be attributable to the high salt load of fosfomycin relative to pip/taz, Dr. Satlin said.

“How might this change your practice? Well, if IV fosfomycin is ever FDA [Food and Drug Administration] approved – and my understanding is that the delays have been more related to manufacturing than scientific quality of data – it could potentially be an alternative to beta-lactams and fluoroquinolones” and has activity against most extend spectrum beta-lactamase (ESBL)–producing Enterobacteriaceae, he said.

Fosfomycin susceptibility testing is challenging, however, with no Clinical & Laboratory Standards Institute (CLSI) or FDA breakpoints for Enterobacterales other than Escherichia coli, and there are questions about the step-down therapy.

“Do you just give a 3-gram sachet chaser when they walk out the door? Do you switch to another agent? I think that needs to be worked out,” he said.
 

 

 

Inhaled amikacin

“We know that some IV antibiotics, particularly for resistant organisms, may not achieve sufficient concentrations in the lung to treat pneumonia. We know that inhaled antibiotics can give a lot of concentration of that drug right at the at the site of infection, but we don’t really have [randomized controlled trial] data to see whether it really helps,” Dr. Satlin said.

The INHALE trial was a double-blind, placebo-controlled superiority trial to see whether adding inhaled amikacin to IV standard-of-care antibiotics could improve outcomes for mechanically ventilated patients with gram-negative pneumonia.

The investigators enrolled 725 adults who were receiving mechanical ventilation for pneumonia, 45% of who had ventilator-associated pneumonia (VAP). Of the total cohort, 508 patients analyzed for efficacy had gram-negative pathogens, including 32% with Pseudomonas aeurginosa, 29% with Acinetobacter baumannii, 30% with E. coli, and the remainder with Klebsiella pneumoniae.

Patients were randomized to standard-of-care intravenous antibiotics plus either inhaled amikacin 400 mg twice daily for 10 days or inhaled saline placebo.

“Of note, the median standard-of-care antibiotics in this study was 18 days, which is certainly longer than what our guidelines recommend.”

There was no significant difference between study arms in the primary endpoint of survival at days 28-32 for all patients who had received at least one dose of study drug, were infected with a gram-negative pathogen, and an Acute Physiology and Chronic Health Evaluation (APACHE) II score of at 10 or higher at diagnosis. The respective survival rates for the inhaled amikacin and placebo groups were 75% and 77%. The incidence of treatment-emergent adverse events or serious treatment-emergent adverse events were similar between the two treatment arms.

“No matter how you sliced and diced it – days of mechanical ventilation, duration of ICU stay – essentially they looked the same.

Survey: Acceptance of COVID-19 vaccine dips below 50%

Article Type
Changed
Thu, 08/26/2021 - 15:58

Less than half of Americans now say that they would get a coronavirus vaccine if one became available, according to a survey conducted Oct. 8-10.

Only 48% of the 2,200 adults participating in the national tracking poll said that they would choose to get vaccinated against the coronavirus, the lowest number since the weekly survey began at the end of February, digital media company Morning Consult reported.

Americans’ willingness to receive such a vaccine reached its high point, 72%, in early April but has been steadily dropping. “Overall willingness has hovered around 50% throughout September, fueled primarily by a sharp drop among Democrats since mid-August, around the time reports of White House interference at the Food and Drug Administration and other federal health agencies began to command more public attention,” Morning Consult noted.

Despite that drop, a majority of Democrats (55%) are still willing to get a COVID-19 vaccine, compared with 48% of Republicans and just 41% of independents. The willingness gap between the two parties was quite a bit wider in the previous poll, conducted Oct. 1-4: 60% of Democrats versus 48% for Republicans, the company said.

“Keeping with longstanding trends, the survey also shows women were less likely to say they’d seek a vaccine than men (42% to 55%), as were people with lower education levels and those who live in rural areas,” the news outlet added.

The latest poll results also show that 33% of respondents (43% of Republicans/25% of Democrats) are socializing in public places. The overall number was just 8% in mid-April but was up to 27% by mid-June. The proportion of all adults who believe in the effectiveness of face masks has been around 80% since April, but there is a significant gap between those who strongly approve of President Trump (66%) and those who strongly disapprove (95%), Morning Consult said.

Proton pump inhibitors tied to COVID-19 risk

Article Type
Changed
Thu, 08/26/2021 - 16:03

People who use proton pump inhibitors (PPIs) may be more likely to get COVID-19, researchers say.

In light of this finding, physicians should consider which patients truly need these powerful acid-lowering drugs, said Brennan Spiegel, MD, MSHS, AGAF, professor of medicine and public health at Cedars Sinai Medical Center in Los Angeles, Calif.

“All it means is that we’re going to have a conversation with our patients,” he said in an interview. “We don’t normally have that conversation because we don’t live in an environment with a high risk of enteric infection. But now we’re in a pandemic.”

The study by Dr. Spiegel and his colleagues was published online on July 7 in the American Journal of Gastroenterology.

Use of PPIs has skyrocketed over the past 2 decades. For ambulatory care visits, their use increased from 1.6% in 1998 to 7.6% in 2015. The increase raised questions about overprescription.

Although studies have not borne out many of the other concerns raised about adverse reactions, they have shown that the drugs increase the risk for enteric infections, including infections by SARS-CoV-1, a virus that is related to the COVID-19 virus, SARS-CoV-2, Dr. Spiegel said.

SARS-CoV-2 uses the angiotensin-converting enzyme–2 receptor to invade enterocytes. Dr. Spiegel theorized that an increase in stomach pH above 3 as a result of use of PPIs might allow the virus to enter the GI tract more easily, leading to enteritis, colitis, and systemic spread to other organs, including the lungs. “There is a reason we have acid in our stomachs,” Dr. Spiegel said.

To see how PPI use relates to COVID-19 infections, Dr. Spiegel and his colleagues surveyed online a nationally representative sample of Americans between May 3 and June 24, 2020, as part of a larger survey on gastroenterologic health.

Participants answered questions about gastrointestinal symptoms, current use of PPIs, and COVID-19 test results. They also answered questions about histamine-2 receptor agonists (H2RAs), also known as H2 blockers, which are used to treat some of the same conditions as PPIs but that do not reduce stomach acid as much.

The surveying firm, Cint, contacted 264,058 people. Of the 86,602 eligible participants who completed the survey, 53,130 said they had experienced abdominal discomfort, acid reflux, heartburn, or regurgitation. These survey participants were subsequently asked about PPI and H2RA use.

Of these, 6.4% reported testing positive for SARS-CoV-2. The researchers adjusted for age, sex, race/ethnicity, education, marital status, household income, body mass index, smoking, alcohol consumption, U.S. region, insurance status, and the presence of irritable bowel syndromeceliac diseasegastroesophageal reflux disease, liver cirrhosisCrohn’s diseaseulcerative colitis, diabetes, and HIV/AIDS.

After adjusting for these factors, the researchers found that those who took PPIs up to once a day were twice as likely to have had a positive COVID-19 test result than those who did not take the drugs (odds ratio, 2.15; 95% confidence interval, 1.90-2.44).

Those who took PPIs twice a day were almost four times as likely to have tested positive for the disease (OR, 3.67; 95% CI, 2.93-4.60).

By contrast, those taking H2RA drugs once daily were 15% less likely to report a positive COVID-19 test result (OR, 0.85; 95% CI, 0.74-0.99). Research is currently underway to determine whether H2RAs might protect against the disease for reasons unrelated to pH balance.

Dr. Spiegel cautioned that the current data show only an association between PPI use and COVID-19 positivity; it cannot prove cause and effect.

Nevertheless, Dr. Spiegel said the findings should encourage physicians to prescribe PPIs only when clearly indicated. “If somebody is not yet on a PPI and you’re considering whether to start them on a PPI, it’s a good idea to consider H2 blockers,” he said.

People who need a daily dose of a PPI to control a severe condition can safely continue doing so, but such patients should take care to follow standard public health recommendations for avoiding exposure to the virus. These recommendations include wearing a mask, maintaining social distance, and washing hands frequently.

“People who are older, comorbid, or smokers – if they get infected, it could be severe,” he said. “[For] someone like that, it’s reasonable to ask, do we really need to be on twice-daily PPIs? There is good evidence that they are no better off than if they are taking once-daily doses.”

Brian Lacy, MD, PhD, a professor of medicine at the Mayo Clinic in Jacksonville, Fla., agreed that the study should prompt physicians to take a second look at their patients’ PPI prescriptions. “My view is that PPIs are frequently overused, and maybe this is one more piece of data that, if someone is on PPIs, maybe they don’t need to be on this medication.”

On the other hand, the drugs are important for treating conditions such as erosive esophagitis and healing ulcers, he said. The overall risk of contracting COVID-19 is low, so even this finding of a 3.7-fold increased risk should not lead patients or providers to stop taking or prescribing PPIs.

The study also lends support to the idea that the gastrointestinal tract could be involved in SARS-CoV-2 transmission, and it supports warnings about aerosols emitted from flushing toilets and through exhalation, Dr. Spiegel said. There is less evidence of the virus being transmitted through food. “It may not be fecal-oral; it may be fecal-respiratory,” he said.

The study was part of a larger project funded by Ironwood Pharmaceuticals. Dr. Spiegel reported relationships with Alnylam Pharmaceuticals, Arena Pharmaceuticals, Ironwood Pharmaceuticals, Salix Pharmaceuticals, Shire Pharmaceuticals, Synergy Pharmaceuticals, and Takeda Pharmaceuticals. Dr. Lacy has disclosed no relevant financial relationships.
