A full 0.5-mL dose of inactivated influenza vaccine was as safe and effective as a was a half dose of 0.25 mL, with slightly higher immunogenicity, according to data from a randomized trial of nearly 2,000 children aged 6-35 months.

Data from previous studies have suggested that a full dose of vaccine may be more immunogenic in young children compared with a half dose, and Sanofi Pasteur has submitted a supplemental Biologics License Application to the Food and Drug Administration to allow use of the full 0.5-mL dose in children as young as 6 months, Monica Mercer, MD, of Sanofi Pasteur, said at a meeting of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices in Atlanta.

Dr. Mercer presented findings from a phase IV randomized, observer-blinded study, in which the researchers assigned healthy children aged 6-35 months to receive Fluzone quadrivalent vaccine at a dose of 0.25 mL or 0.5 mL.

A total of 1,941 children (949 for the 0.25-mL dose and 992 for the 0.5-mL dose) were included in the safety analysis.

The most important safety outcome was to compare the rate of any fever, Dr. Mercer said at the meeting.

Overall, at 7 days after vaccination, the rate of fever was 11% for the half dose and 12% for the full dose, she said. The resulting difference of 0.84% met the criteria for noninferiority (less than 5%), she added.

In terms of safety, tenderness was the most frequently reported injection site reaction, noted in 47% of the half-dose group and 50% of the full-dose group. The rates of unsolicited adverse events were similar in both groups, the most common included diarrhea and cough, Dr. Mercer said.

No subjects in the full-dose group and three in the half-dose group discontinued the study because of adverse events. The only reported serious adverse event was one case of chronic urticaria in the half-dose group; no deaths were reported in either group.

As for efficacy, the full dose demonstrated noninferiority, compared with the half dose, against each of four strains: influenza A H1N1, influenza A H3N2, influenza B Victoria, and influenza B Yamagata. The geometric mean titers of the full and half doses for each of the four strains were, respectively, 310 and 214, 332 and 221, 348 and 261, and 349 and 243.

The potential action date for the supplemental Biologics License Application is January 2019, noted Dr. Mercer, who is employed by Sanofi Pasteur.

A review of more than 1,000 hospitalizations revealed a 40% influenza vaccine effectiveness against laboratory-confirmed influenza-associated hospitalizations during pregnancy, Mark Thompson, MD, said at a meeting of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices in Atlanta.

To date, no study has examined influenza vaccine effectiveness (IVE) against hospitalizations among pregnant women, said Dr. Thompson, of the CDC’s influenza division.

He presented results of a study based on data from the Pregnancy Influenza Vaccine Effectiveness Network (PREVENT), which included public health or health care systems with integrated laboratory, medical, and vaccination records in Australia, Canada (Alberta and Ontario), Israel, and three states (California, Oregon, and Washington). The study included women aged 18-50 years who were pregnant during local influenza seasons from 2010 to 2016. Most of the women were older than 35 years (79%), and in the third trimester (65%), and had no high risk medical conditions (66%). The study was published in Clinical Infectious Diseases (2018 Oct 11. doi: 10.1093/cid/ciy737).

The researchers identified 19,450 hospitalizations with an acute respiratory or febrile illness discharge diagnosis and clinician-ordered real-time reverse transcription polymerase chain reaction (rRT-PCR) testing for flu viruses. Of these, 1,030 (6%) of the women underwent rRT-PCR testing, 54% were diagnosed with either influenza or pneumonia, and 58% had detectable influenza A or B virus infections.

Overall, the adjusted IVE was 40%; 13% of rRT-PCR-confirmed influenza-positive pregnant women and 22% of influenza-negative pregnant women were vaccinated; IVE was adjusted for site, season, season timing, and high-risk medical conditions.

“The takeaway is this is the average performance of the vaccine across multiple countries and different seasons,” and the vaccine effectiveness appeared stable across high-risk medical conditions and trimesters of pregnancy, Dr. Thompson said.

The generalizability of the study findings was limited by the lack of data from low- to middle-income countries, he said during the meeting discussion. However, the ICU admission rate is “what we would expect” and similar to results from previous studies. The consistent results showed the need to increase flu vaccination for pregnant women worldwide and to include study populations from lower-income countries in future research.

Dr. Thompson had no financial conflicts to disclose.

The recent rise in pertussis rates may have peaked, but the experts are responding by reinstating a working group.

The new working group for pertussis was announced at a meeting of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices. The ACIP’s new group, led by Fiona Havers, MD, of the CDC, heard data on the currently available pertussis vaccines and solicited ideas from ACIP members about what other data they would like before the February meeting.

One question on the agenda is whether the current recommendation that nonpregnant adults receive a single lifetime dose of Tdap and then tetanus-diphtheria (Td) boosters every 10 years be expanded to allow either Tdap or Td as the booster. Reasons for considering the change include possible changes in the circulating pertussis strain, improved diagnosis and reporting, and the waning of protection under the current guidelines, as well as the potential economic impact, Dr. Havers said.

This change could make booster administration easier for many physicians who do not routinely stock Td, some committee members noted. In addition, the Food and Drug Administration has approved a label change for one Tdap manufacturer to remove “single use” language.

In a study presented by David P. Greenberg, MD, associate vice president of Sanofi Pasteur, seroprotection rates to tetanus and diphtheria were similar in a comparison between groups of adults aged 18 years and older, receiving either Tdap (Adacel) or Td as a booster. “Seroprotection was greater than 99% in both groups,” he said.

Pain was the most common injection site reaction in both groups, rates of serious adverse events were similarly low (0.8% and 0.3%, respectively), and no deaths occurred in patients given either vaccine.

The postvaccination antipertussis geometric mean concentrations were noninferior in the Tdap group, compared with the Td group, Dr. Greenberg said.

A phase III open label study presented by Leonard Silverstein, MD, of GlaxoSmithKline also showed similar seroprotection rates for adults revaccinated with Tdap after an initial vaccination with either of two different Tdap vaccines.

Also at the February meeting, the committee will address whether any vaccine that contained Td should be allowed for use as tetanus prophylaxis in the setting of wound management, said Dr. Havers.

The committee members expressed interest in more information on several topics including pregnancy and pertussis, whether manufacturers could discuss vaccines in the pipeline, data on responses to multiple doses and if there is a point of diminishing returns, and whether some states are covering Tdap for adults.

The committee members had no financial conflicts to disclose.

The Food and Drug Administration has cleared Xyrem (sodium oxybate) oral solution to treat cataplexy and excessive daytime sleepiness in patients ages 7-17 with narcolepsy.

The central nervous system depressant previously had been approved to treat cataplexy in adults with narcolepsy.

The current approval was granted by the FDA under a Priority Review designation. Xyrem also received the FDA’s Orphan Drug designation, which is intended to encourage the development of drugs for rare diseases.

The agency noted in a press release, however, that the drug would continue to be available only through risk evaluation mitigation strategy (REMS) programs because of “the risk of serious outcomes resulting from inappropriate prescribing, misuse, abuse and diversion.” Xyrem either alone or in combination with other CNS depressants may be associated with reactions including seizure, respiratory depression, decreases in the level of consciousness, coma, and death, the FDA said.

The most common adverse reactions in pediatric patients were enuresis, nausea, headache, vomiting, weight decrease, decreased appetite, and dizziness.

The antipsychotic medications haloperidol and ziprasidone are no better than placebo in altering the duration of delirium in patients in intensive care, new research has found.

copyright Andrei Malov/Thinkstock

In a paper published in the New England Journal of Medicine, researchers reported the results of a randomized, double-blind, placebo-controlled trial in 566 patients with acute respiratory failure or shock and hypoactive or hyperactive delirium. Participants were randomized either to a maximum of 20 mg IV haloperidol daily, maximum 40 mg ziprasidone daily, or placebo.

At the end of the 14-day intervention period, the placebo group had a median of 8.5 days alive without delirium or coma, the haloperidol group had a median of 7.9 days, and the ziprasidone group had a median of 8.7 days. The difference between groups was not statistically significant.

There were also no significant differences between the three groups in the secondary end point of duration of delirium and coma, 30-day and 90-day survival, time to freedom from mechanical ventilation, ICU discharge, ICU readmission, or hospital discharge.

Timothy D. Girard, MD, from the department of critical care at the University of Pittsburgh, and his coauthors wrote that their findings echoed those of two previous placebo-controlled trials in smaller numbers of ICU patients.

“One possible reason that we found no evidence that the use of haloperidol or ziprasidone resulted in a fewer days with delirium or coma than placebo is that the mechanism of brain dysfunction that is considered to be targeted by antipsychotic medications – increased dopamine signaling – may not play a major role in the pathogenesis of delirium during critical illness,” they wrote.

“In the current trial, approximately 90% of the patients received one or more doses of sedatives or analgesics, and the doses of sedatives and offtrial antipsychotic medications and the durations of exposures to those agents were similar in all trial groups,” the authors added.

Most of the patients in the trial had hypotensive delirium, which made it difficult to assess the effects of antipsychotics on hypertensive delirium.

The authors also commented that the patients enrolled were a mixed group, so their findings did not rule out the possibility that certain subgroups of patients – such as nonintubated patients with hyperactive delirium, those with alcohol withdrawal, or with other delirium phenotypes – may still benefit from antipsychotics.

Patients treated with ziprasidone were more likely to experience prolongation of the corrected QT interval. Two patients in the haloperidol group developed torsades de pointes but neither had received haloperidol in the 4 days preceding the onset of the arrhythmia.

One patient in each group – including the placebo group – experienced extrapyramidal symptoms and had treatment withheld. One patient in the haloperidol group also had the trial drug withheld because of suspected neuroleptic malignant syndrome, but this was later ruled out, and one patient had haloperidol withheld because of dystonia.

The dose of haloperidol used in the study was considered high, the authors said, but they left open the possibility that even higher doses might help. However, they also noted that doses of 25 mg and above were known to have adverse effects on cognition, which is why they chose the 20-mg dosage.

The study was supported by the National Institutes of Health and the Department of Veterans Affairs Geriatric Research Education and Clinical Center. Most authors declared support from the NIH or VA during the course of the study. Four authors also reported fees and grants from private industry outside the context of the study.

“One possible reason that we found no evidence that the use of haloperidol or ziprasidone resulted in a fewer days with delirium or coma than placebo is that the mechanism of brain dysfunction that is considered to be targeted by antipsychotic medications – increased dopamine signaling – may not play a major role in the pathogenesis of delirium during critical illness,” they wrote.

“In the current trial, approximately 90% of the patients received one or more doses of sedatives or analgesics, and the doses of sedatives and offtrial antipsychotic medications and the durations of exposures to those agents were similar in all trial groups,” the authors added.

Most of the patients in the trial had hypotensive delirium, which made it difficult to assess the effects of antipsychotics on hypertensive delirium.

The authors also commented that the patients enrolled were a mixed group, so their findings did not rule out the possibility that certain subgroups of patients – such as nonintubated patients with hyperactive delirium, those with alcohol withdrawal, or with other delirium phenotypes – may still benefit from antipsychotics.

Patients treated with ziprasidone were more likely to experience prolongation of the corrected QT interval. Two patients in the haloperidol group developed torsades de pointes but neither had received haloperidol in the 4 days preceding the onset of the arrhythmia.

One patient in each group – including the placebo group – experienced extrapyramidal symptoms and had treatment withheld. One patient in the haloperidol group also had the trial drug withheld because of suspected neuroleptic malignant syndrome, but this was later ruled out, and one patient had haloperidol withheld because of dystonia.

The dose of haloperidol used in the study was considered high, the authors said, but they left open the possibility that even higher doses might help. However, they also noted that doses of 25 mg and above were known to have adverse effects on cognition, which is why they chose the 20-mg dosage.

The study was supported by the National Institutes of Health and the Department of Veterans Affairs Geriatric Research Education and Clinical Center. Most authors declared support from the NIH or VA during the course of the study. Four authors also reported fees and grants from private industry outside the context of the study.

The Influenza A & B 2 assay can detect and differentiate influenza A and B in 13 minutes, with a call-out of positive results at 5 minutes. It can be stored at room temperature, simplifying storage and ordering. The Strep A 2 assay detects group A streptococcus bacterial nucleic acid in 6 minutes, with a call-out of positive results at 2 minutes. Both will be the fastest tests currently on the market in their respective fields, according to a corporate press release.

The assays will be available in a variety of inpatient and outpatient settings, particularly in locations where patients commonly access health care services, such as EDs, physician offices, walk-in clinics, and urgent care centers. This will allow health care providers to make a fast, informed diagnosis and provide appropriate treatment within the span of a single patient visit.

“The ability to obtain early call outs for positive test results with molecular accuracy in as little as 5 minutes for influenza and 2 minutes for strep A is a game-changing development that allows prompt treatment decisions at the point of care. Rapid testing may also help reduce improper antibiotic usage, which can occur when treatment is based exclusively on a patient’s symptoms, and contributes to antibiotic resistance,” Gregory J. Berry, PhD, director of molecular diagnostics at Northwell Health Laboratories in Lake Success, N.Y., said in the press release.

Clinicians consulting the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices vaccination schedules for children, adolescents, and adults in 2019 will find a simpler design and more useful product, according to David Kim, MD, of the Immunization Services Division of the Centers for Disease Control and Prevention, Atlanta.

In a single vote to cover both adult and child/adolescent schedules, the committee voted unanimously in favor of a redesign of the schedules and several clinical updates.

In 2016, the working group for vaccination schedules conducted an ad hoc evaluation of the adult schedule to assess its usability, Dr. Kim said at a meeting of the CDC’s ACIP.

The design of the adult schedule was fully evaluated in 2018 via a three-step process – interviews with 48 health care providers, a redesign of the schedule, and a survey after the redesign. Design changes to the child/adolescent schedule were harmonized with the adult schedule, Dr. Kim explained.

The adult vaccination schedule itself includes several updates in ACIP recommendations in addition to the aesthetic design changes.

The 2019 Adult Immunization Schedule includes the option of the live attenuated influenza vaccine (LAIV) for influenza, the addition of homelessness as an indication for hepatitis A vaccination, and the use of CpG-adjuvanted hepatitis B vaccine, Dr. Kim said.

The additions to the 2019 Child and Adolescent Immunization Schedule are the optional use of the LAIV for influenza, the addition of homelessness as an indication for hepatitis A vaccination, the use of CpG-adjuvanted hepatitis B vaccine (a cytosine phosphoguanosine oligodeoxynucleotide adjuvant), and the addition of the Tdap vaccination of individuals who received Tdap at age 7-10 years.

Some of the key design changes include the use of bright purple on the child/adolescent schedule to more easily distinguish it from the adult version, said Dr. Kim.

Other changes to both schedules include shorter titles, lists of vaccines and trade names, and compartmentalized information for easier reference. Figures have been replaced by tables, and footnotes are simply “Notes” at the end of the schedule, compartmentalized for easier reading, he said. In addition, the schedules include resources for vaccination in outbreak situations and a section on how to report vaccine preventable disease outbreaks.

The ACIP committee members had no relevant financial conflicts to disclose.

SAN ANTONIO – Obstructive sleep apnea (OSA) in children is associated with an abnormal metabolic profile, but not with body mass index (BMI), according to new research.

Tara Haelle/MDedge News

“Screening for metabolic dysfunction in obese children with obstructive sleep apnea can help identify those at risk for cardiovascular complications,” Kanika Mathur, MD, of the Albert Einstein College of Medicine and the Children’s Hospital at Montefiore, both in New York, told attendees at the annual meeting of the American College of Chest Physicians. Dr. Mathur explained that no consensus currently exists regarding routine cardiac evaluation of children with OSA.

“The American Academy of Pediatrics does not mention any sort of cardiac evaluation in children with OSA while the most recent guidelines from the American Heart Association and the American Thoracic Society recommend echocardiographic evaluation in children with severe obstructive sleep apnea, specifically to evaluate for pulmonary hypertension and right ventricular dysfunction,” Dr. Mathur told attendees.

OSA’s association with obesity, diabetes, and hypertension is well established in adults. It is an independent risk factor for coronary artery disease, heart failure, stroke and atrial fibrillation, and research has suggested OSA treatment can reduce cardiovascular risk in adults, Dr. Mathur explained, but little data on children exist. She and her colleagues set out to understand the relationship of OSA in children with various measures of cardiovascular and metabolic health.

“Despite similar degrees of obesity and systemic blood pressure, pediatric patients with OSA had significantly higher diastolic blood pressure, heart rate, and abnormal metabolic profile, including elevated alanine transaminase, aspartate transaminase, triglycerides and hemoglobin A_1c,” they found.

Their study included patients aged 3-21 years with a BMI of at least the 95th percentile who had undergone sleep study and an echocardiogram at the Children’s Hospital at Montefiore between November 2016 and November 2017.

They excluded those with comorbidities related to cardiovascular morbidity: heart disease, neuromuscular disease, sickle cell disease, rheumatologic diseases, significant cranial facial abnormalities, tracheostomy, and any lung disease. However, 7% of the patients had trisomy 21.

Among the 81 children who met their criteria, 37 were male and 44 were female, with an average age of 14 years old and a mean BMI of 39.4 kg/m² (mean BMI z score of 2.22). Most of the patients (53.1%) had severe OSA (apnea-hypopnea index of at least 10), 21% had moderate OSA (AHI 5-9.9), 12.3% had mild OSA (AHI 2-4.9), and 13.6% did not have OSA. The median AHI of the children was 10.3.

Among all the children, “about half had elevated systolic blood pressure, which is already a risk factor for cardiovascular morbidity,” Mathur reported.

BMI, BMI z score, systolic blood pressure z score, oxygen saturation and cholesterol (overall and both HDL and LDL cholesterol levels) did not significantly differ between children who had OSA and those who did not, but diastolic blood pressure and heart rate did. Those with OSA had a diastolic blood pressure of 65 mm Hg, compared with 58 mm Hg without OSA (P = .008). Heart rate was 89 bpm in the children with OSA, compared with 78 bpm in those without (P = .004).

The children with OSA also showed higher mean levels of several other metabolic biomarkers:

• Alanine transaminase: 26 U/L with OSA vs. 18 U/L without (P = .01).
• Aspartate transaminase: 23 U/L with OSA vs. 18 U/L without (P = .03).
• Triglycerides: 138 mg/dL with OSA vs 84 mg/dL without (P = .004).
• Hemoglobin A_1c: 6.2% with OSA vs. 5.4% without (P = .002).

Children with and without OSA did not have any significant differences in left atrial indexed volume, left ventricular volume, left ventricular ejection fraction, or left ventricular mass (measured by M-mode or 5/6 area length formula). Though research has shown these measures to differ in adults with and without OSA, evidence on echocardiographic changes in children has been conflicting, Dr. Mathur noted.

The researchers also conducted subanalyses according to OSA severity, but BMI, BMI Z-score, systolic or diastolic blood pressure Z-score, heart rate and oxygen saturation did not differ between those with mild OSA vs those with moderate or severe OSA. No differences in echocardiographic measurements existed between these subgroups, either.

However, children with moderate to severe OSA did have higher alanine transaminase (27 U/L with moderate to severe vs. 17 U/L with mild OSA; P = .005) and higher triglycerides (148 vs 74; P = .001).

“Certainly we need further evaluation to see the efficacy of obstructive sleep apnea therapies on metabolic dysfunction and whether weight loss needs to be an adjunct therapy for these patients,” Dr. Mathur told attendees. She also noted the need to define the role of echocardiography in managing children with OSA.

The study had several limitations, including its retrospective cross-sectional nature at a single center and its small sample size.

“Additionally, we have a wide variety of ages, which could represent different pathophysiology of the associated metabolic dysfunction in these patients,” Mathur said. “There is an inherent difficulty to performing echocardiograms in a very obese population as well.”

Both the moderators of the pediatrics section, Christopher Carroll, MD, FCCP, of Connecticut Children’s Medical Center in Hartford, and Shahid Sheikh, MD, FCCP, of Nationwide Children’s Hospital in Columbus, Ohio, were impressed with the research. Dr. Carroll called it a “very elegant” study, and Dr. Sheikh noted the need for these studies in pediatrics “so that we don’t have to rely on grown-up data,” which may or may not generalize to children.

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.”

“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.”

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 Food and Drug Administration has extended the indication for a quadrivalent influenza vaccine (Afluria, marketed by Seqirus) to include infants and younger children.

The expanded approval now includes persons aged 6-59 months; the quadrivalent vaccine had previously been approved for ages 5 years and up. A trivalent version of the Afluria influenza vaccine also now is indicated for people aged 6 months and up, according to an Oct. 4 communication from the FDA.

A total of 172 pediatric influenza-related deaths occurred in the United States during the 2017-2018 season, representing a new high in nonpandemic influenza seasons. About half of the pediatric influenza deaths occurred in otherwise healthy children, and about 22% of children who died were fully vaccinated, according to the Centers for Disease Control and Prevention, reporting U.S. data from 2010 to 2016.

“As we enter a new flu season, we are reminded of the enormous impact that influenza can have on public health,” Seqirus’ vice president of medical affairs Gregg Sylvester, MD, said in a press release announcing the extended indication. “Having another option to fight this disease can translate to saved lives and fewer flu-related hospitalizations this season and going forward.”

According to the CDC, the 2018-2019 influenza vaccine has been updated to provide a better match – and more protection against – viruses circulating in this influenza season. Specifically, says the CDC, the influenza B Victoria lineage and the influenza A(H3N2) components were updated.

In addition to providing protection against these two strains of influenza, trivalent vaccines for the 2018-2019 season are recommended to include protection against H1N1 influenza as well. Quadrivalent vaccines protect against a second influenza B lineage.

Most people will receive a quadrivalent vaccine this year, according to the CDC.
