Prescriptions for cough, cold medicine dropping for children
with evidence suggesting replacement by off-label antihistamines, according to analysis of two national databases.
Compared with older children, declines in both opioid and nonopioid cold and cough medicine (CCM) use “appeared to accelerate in children younger than 2 years … and among children younger than 6 years for opioid-containing CCM” after the Food and Drug Administration’s 2008 public health advisory on use of OTC forms of CCM, Daniel B. Horton, MD, of the Robert Wood Johnson Medical School, New Brunswick, N.J., and his associates wrote in JAMA Pediatrics.
Meanwhile, recommendations for single-agent antihistamines rose – for some age groups significantly – over the 14-year study period, which was divided into two eras: 2002-2008 and 2009-2015.
When the two eras were compared, trends for decreased use of CCM in children under 2 years of age (nonopioid) and under 4 years (opioid) approached – both were P = .05 – but did not quite reach the less than .05 considered statistically significant. Adjusted odds ratios for the other age groups were further off the mark. For antihistamines, the upward trend between the two eras was significant for children aged under 2 years, 2-3 years, and 6-11 years, Dr. Horton and associates reported.
The two youngest groups, under 2 years and 2-3, were combined for the opioid CCM analyses to avoid a population under 30, which would have yielded unreliable estimates. The investigators used data from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey, with the sample representing 3.1 billion pediatric visits from 2002 to 2015.

Best inhaler for COPD is the one the patient will use
ORLANDO –
That’s according to Gabriel Ortiz, MPAS, PA-C, DFAAPA, a speaker at the Cardiovascular & Respiratory Summit by Global Academy for Medical Education.
There are several treatment options available in inhaler form for patients with COPD, including short-acting and long-acting beta2-agonists (SABA/LABA), short-acting and long-acting antimuscarinics (SAMA/LAMA), combination therapy, and triple therapy. But education and training on how to use an inhaler is also important, Mr. Ortiz said in his presentation.
Providers should help a patient choose an inhaler they are most likely to use. “It’s difficult to actuate and inhale, so there’s a lot of education that goes into that,” said Mr. Ortiz, of Pediatric Pulmonary Services in El Paso, Texas. “What we do for our patients is, we educate them, we tell them to demonstrate it, then bring [the] inhaler back on the next visit and demonstrate to us every time.”
“Make sure that they demonstrate because, as patients get older, they may lose their ability to actuate and inhale,” he added.
Adherence to therapy should also be considered before changing from a current therapy, he added. Mr. Ortiz described a scenario in which a prescription was filled, but because of the cost, the patient reduced the dose by half to make the therapy last longer.
“We could be the best providers in the world, prescribing the best medication in the world. If the medication doesn’t get to where we need it, it’s not going to help anybody,” he said.
Providers should also use nonpharmacological treatments to prevent or keep COPD from progressing. Smoking cessation is key to reducing the risk of developing COPD, and it is not clear whether e-cigarettes aid in smoking cessation, despite companies that market these products making that claim. “We have a huge e-cigarette epidemic here,” he said.
Instead, Mr. Ortiz recommended identifying which patients are current tobacco users, encouraging them to quit, determining whether the patient is willing to make a commitment to cut down on tobacco use or stop entirely, helping draft a quit plan and obtaining intra- and extratreatment social support for smoking cessation, and scheduling follow-up. Providers should discuss smoking cessation at each visit, and it may take multiple visits before a patient is willing to consider quitting, he said.
Another measure providers can take is making sure patients with COPD have received influenza and pneumococcal vaccinations because this can lower the risk of respiratory tract infections. Physical activity, training in exercise, nutritional support, and pulmonary rehabilitation can improve their health status, dyspnea, and exercise tolerance. While C-level evidence shows education alone is not effective according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, providers working with patients through self-management interventions have been shown to improve health status and decrease COPD-related hospitalizations.
Oxygen therapy has been effective for patients with severe resting chronic hypoxia and improves survival, said Mr. Ortiz. For patients who gradually decline in health despite treatment, palliative, hospice, and end-of-life care may be an option. “Remember that as acute exacerbations continue, that increases the risk of death,” he said. “We want to try and prevent [those] exacerbations and improve quality of life.”
During follow-up visits, providers should continue performing spirometry tests annually to measure decline in forced expiratory volume in 1 second, information on symptoms that have presented since the previous visit, details of any exacerbations that occurred, and current smoking status. When making decisions to adjust therapy, providers should examine the effectiveness of the current regimen and consider the dose of prescribed medications, whether the patient is adhering to the regimen, inhaler technique, and any side effects.
Mr. Ortiz reports also being a paid employee for Thermo Fisher, a biotechnology product development company based in Waltham, Mass. Global Academy for Medical Education and this news organization are owned by the same parent company.

EXPERT ANALYSIS FROM CARPS 2019
FDA advisors recommend nintedanib for SSc interstitial lung disease
The Food and Drug Administration Arthritis Advisory Committee recommended approval of nintedanib for the treatment of interstitial lung disease in patients with systemic sclerosis by a 10-7 vote on July 25, 2019. If the FDA acts in accord with the panel’s recommendation, it would make nintedanib (Ofev) the first drug to receive marketing approval for this indication.
Nintedanib has had FDA approval for treating idiopathic pulmonary fibrosis since 2014, and the manufacturer, Boehringer Ingelheim, designed the current pivotal trial with 576 patients to broaden the indication to patients with a different but similar fibrotic lung disease, interstitial lung disease (ILD), that is a common and eventually lethal complication of systemic sclerosis. The results of the pivotal study, the SENSCIS (Safety and Efficacy of Nintedanib in Systemic Sclerosis) trial, recently appeared in print and showed that patients randomized to receive 150 mg of nintedanib orally twice daily had an average 41-mL cut in the rate of loss of forced vital capacity (FVC) during 52 weeks on treatment, compared with those randomized to placebo. This was a 44% relative reduction in rate of FVC loss that was statistically significant for the study’s primary endpoint (N Engl J Med. 2019 June 27;380[26]:2518-28).
Votes in favor of FDA approval for many on the panel seemed to stem from a combination of the fact that nintedanib met the pivotal trial’s primary endpoint; which had been developed in consultation with the FDA, as well as the absence of any new safety signals when compared with prior experience using the drug; the lack of any treatment specifically recognized as beneficial to systemic sclerosis patients who develop the terminal complication of ILD; and the challenge of running a second trial in an orphan disease with an estimated U.S. prevalence of no more than 100,000 patients. Several committee members who voted in favor of nintedanib’s approval also voiced concern that the case in favor of its benefit/risk balance was not open and shut.
“I have a fair amount of apprehension,” admitted the committee’s chair, Daniel H. Solomon, MD, a rheumatologist and professor of medicine at Harvard Medical School, Boston. “I support the needs of patients, but we don’t want to give them false hope. We need to be able to say who will benefit, and the single study [SENSCIS] results don’t tell us how to use the drug. I want to understand which patient subgroups benefit.” He suggested that the FDA mandate further data collection through postmarketing studies.
Comments from panel members who voted against recommending approval generally focused on what was generally agreed to be a very modest treatment effect with a 41-mL average difference in FVC decline that has marginal clinical meaningfulness. Although the SENSCIS results met the study’s primary endpoint it was neutral for all prespecified secondary endpoints, including a measure of quality of life, although many on the panel agreed that a good measure of quality of life in the target patient population is lacking. Some sensitivity analyses run by FDA staffers also failed to confirm the primary result. Fewer questions arose about safety, although some panelists expressed concern about gastrointestinal effects, especially diarrhea, that seemed to link with treatment, as well as a signal for an increased incidence of pneumonia among patients on nintedanib. The data also showed a possible signal of reduced efficacy among patients who also received treatment with the immunosuppressive agent mycophenolate mofetil, often used off label to treat systemic sclerosis patients with ILD. However, a statistician involved in the discussion warned against overinterpreting this or other subgroup analyses.
Dr. Solomon has received research support from AbbVie, Amgen, Bristol-Myers Squibb, Genentech, Janssen, and Pfizer.

PHiD-CV with 4CMenB safe, effective for infants
Concomitant administration of pneumococcal and meningococcal vaccines is not only safe but also offers the potential to improve vaccine uptake and reduce the number of doctors’ visits required for routine vaccination, advised Marco Aurelio P. Safadi, MD, PhD, of Santa Casa de São Paulo School of Medical Sciences, Brazil, and associates.
In a post hoc analysis of a phase 3b open-label study, Dr. Safadi and associates sought to evaluate immune response in pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) administered concomitantly with either meningococcal serogroup B (4CMenB) vaccine and CRM-conjugated meningococcal serogroup C vaccine (MenC-CRM) or with MenC-CRM alone using reduced schedules in 213 healthy infants aged 83-104 days. Study participants were enrolled and randomized to one of two groups between April 2011 and December 2014 at four sites in Brazil (Vaccine. 2019 Jul 18. doi: 10.1016/j.vaccine.2019.07.021).
Similar immune response was seen with vaccine serotypes and vaccine-related pneumococcal serotypes 6A and 19A in children who had received concomitant administration of PHiD-CV, 4CMenB, and MenC-CRM without 4CMenB.
Dr. Safadi and associates pointed out that PHiD-CV was given in accordance with a 3+1 dosing schedule, while 4CMenB used a reduced 2+1 schedule, which was observed to produce an immune response and provide an acceptable safety profile.
The findings yielded valuable information for the 2+1 PHiD-CV vaccination schedule, which was recently introduced in Brazil, the researchers said. The post-booster results further reflect the “immunogenicity following 3-dose priming.”
The post hoc nature of this study design effectively demonstrated that or with MenC-CRM alone, they explained.
The study was supported by GlaxoSmithKline (GSK) Biologicals. Three authors are employees of the GSK group of companies, and three others received a grant from the GSK companies, two of whom received compensation from other pharmaceutical companies. The institution of one of the authors received clinical trial fees from the GSK companies, and received personal fees/nonfinancial support/grants/other from the GSK companies and many other pharmaceutical companies.

The post hoc nature of this study design effectively demonstrated that or with MenC-CRM alone, they explained.
The study was supported by GlaxoSmithKline (GSK) Biologicals. Three authors are employees of the GSK group of companies, and three others received a grant from the GSK companies, two of whom received compensation from other pharmaceutical companies. The institution of one of the authors received clinical trial fees from the GSK companies, and received personal fees/nonfinancial support/grants/other from the GSK companies and many other pharmaceutical companies.

Air pollution levels correlated with cardiorespiratory mortality, reduced life expectancy
particularly among lower-income populations, research suggests.
A study published in PLOS Medicine used vital registration and population data from across the United States for 1999-2015 to estimate the number of deaths and loss of life expectancy associated with four different models of concentrations of fine particulate matter pollution, and examine how that has changed over time.
While the current national ambient air quality standard for particle pollution is 12 mcg/m3 in almost all counties, the study found that in 1999, 59% of the 1,339 county units had concentrations above this level. At that time, the population-weighted average fine particulate matter pollution concentration for the entire country was 13.6mcg/m3. The highest level was seen in Fresno county in California, which had a fine particulate pollution concentration of 22.1 mcg/m3.
By 2015, national concentrations had declined to 8.0 mcg/m3, and the lowest observed concentration was 2.8 mcg/m3.
The investigators wrote, “Each model was applied to county-level cardiorespiratory death rates separately by sex and age group (5-year age groups from birth to 85 years and 85 years and older) because death rates vary by age group and sex, as might their associations with air pollution. From each model we estimated age-specific proportional increases in death rates (i.e. rate ratios) for each 1 mcg/m3 of PM2.5 [fine particulate matter].” The analysis revealed that fine particulate matter pollution above the lowest observed concentration of 2.8 mcg/m3 was associated with higher death rates from cardiorespiratory diseases.
Overall, researchers estimated that these higher levels contributed to 15,612 deaths from cardiorespiratory diseases in women and 14,757 deaths in men, representing 2.8% and 2.7% of all cardiorespiratory deaths, respectively. This amounted to 0.15 years of life expectancy lost in women and 0.13 years lost in men.
There was significant variation in the cost to life expectancy around the country. In the midwestern and Rocky Mountain counties in states such as New Mexico, Colorado, and Arizona, which had lower levels of air pollution, life expectancy loss was less than 0.05 years. But in southern states where the air pollution levels were highest, such as Arkansas, Oklahoma, Alabama, and around Los Angeles, the life expectancy loss was greater than 0.3 years.
“While current PM2.5 pollution is responsible for a significant mortality burden and loss of longevity, reductions in pollution since the late 1990s have benefited virtually the entire country, with the exception of 14 counties where PM2.5 increased slightly over this period,” wrote James E. Bennett, PhD, of the School of Public Health at Imperial College London and coauthors.
The primary limitation of the study is that this association between air pollution and cardiorespiratory health or life expectancy cannot be shown to be causal. Other pollutants and other environmental and behavioral factors that impact cardiorespiratory health may be significant. For example, including ozone and nitrogen dioxide levels in the models could result in different results in terms of the impact of PM2.5 on cardiorespiratory health.
The data highlighted that life expectancy loss associated with air pollution was larger in lower-income counties, those where a higher proportion of the population had a family income below the poverty line, and those where a higher proportion of the population were black or African American.
“This inequality in mortality burden occurs because lower-income counties, those with more poverty, with a greater proportion who are of black or African American race, or with a lower proportion who have graduated high school tend to have higher baseline death rates at any pollution level because of conditions associated with these covariates and hence experience a larger absolute number of deaths as a result of air pollution,” the authors wrote.

New measles outbreaks reported in Los Angeles and El Paso
according to the Centers for Disease Control and Prevention.
The total number of confirmed cases of measles in the United States is now up to 1,148 for the year, which is 25 more than the previous week, the CDC said on July 22. The highest 1-week total for the year was the 90 cases reported during the week of April 11.
The number of outbreaks is back up to five as California returned to the list after a 1-week absence and El Paso, Tex., made its first appearance of the year. The current outbreak in California – the state’s fifth – is occurring in Los Angeles, which is now up to 16 total cases in 2019. El Paso just reported its fourth case on July 17, and the city’s health department noted that “it had been more than 25 years since El Paso saw its last case of measles before these four recent cases.” Outbreaks also are ongoing in Rockland County, N.Y.; New York City; and three counties in Washington State.
States that joined the ranks of the measles-infected during this most recent reporting week were Alaska and Ohio, which brings the total number to 30 for the year, the CDC said.
The Alaska Department of Health and Social Services said that it “has confirmed a single case of measles in an unvaccinated teenager from the Kenai Peninsula who recently traveled out of state to Arizona via Seattle.” The Ohio case is a “young adult from Stark County [who] recently traveled to a state with confirmed measles cases,” according to the state’s health department.

Atherosclerotic disease risk persists decades after smoking cessation
Adults who quit smoking reduced their risk for peripheral artery disease in the short term, but remained at increased risk for up to 30 years, compared with never-smokers, based on data from more than 13,000 adults in a community-based study.
Most reports on the impact of smoking cessation on cardiovascular disease have focused on coronary heart disease (CHD), and stroke, while data on the effects of smoking cessation on peripheral artery disease (PAD) are limited, wrote Ning Ding, MBBS, SCM, of the Johns Hopkins Bloomberg School of Public Health, Baltimore, Md., and colleagues.
To compare the impact of smoking on PAD, CHD, and stroke, the researchers used data from the Atherosclerosis Risk in Communities (ARIC) study, which included 15,792 adults aged 45-64 years in four communities. The findings were published in the Journal of the American College of Cardiology.
The study population of 13,355 individuals had no baseline history of PAD, CHD, or stroke. Over a median 26 years of follow-up, the researchers identified 492 cases of PAD, 1,798 cases of CHD, and 1,106 cases of stroke.
The risk of all three conditions began to decline within 5 years of smoking cessation, which could be encouraging to smokers who wish to quit, the researchers noted. In addition, the longer the duration of smoking cessation, the lower the risk for all three conditions (See central illustration).
However, a significantly elevated risk remained for PAD for up to 30 years after smoking cessation and for CHD for up to 20 years after smoking cessation, compared with never-smokers.
The researchers also found a roughly fourfold increased risk for PAD for smokers who smoked for 40 or more pack-years, compared with never-smokers, which was greater than the 2.1 hazard ratio for CHD and 1.8 HR for stroke. In addition, current smokers of at least one pack per day had a significantly greater risk of PAD, compared with never-smokers (HR, 5.36) that was higher than the risk for CHD or stroke (HR, 2.38 and HR, 1.88, respectively).
The study findings were limited by several factors including the reliance on self-reports, potential misclassification of data, and the potential exclusion of mild PAD cases that did not require hospitalization, the researchers noted. However, the results support the value of encouraging smokers to quit and support the need to include PAD risk in public health information, they said. “Although public statements about smoking and [cardiovascular disease] have been focusing on CHD and stroke, our results indicate the need to take account of PAD as well for comprehensively acknowledging the effect of smoking on overall cardiovascular health,” they added.
The ARIC study was funded by the National Heart, Lung, and Blood Institute, National Institutes of Health. Lead author Dr. Ding had no financial conflicts to disclose; coauthors disclosed relationships with Bristol-Myers Squibb and Fukuda Denshi.

Although the pathophysiology of smoking and cardiovascular disease has yet to be teased out, the current study findings support the public health message that any and all smokers can improve their health by quitting any time: “It is never too early or too late to benefit from quitting,” wrote Nancy A. Rigotti, MD, and Mary M. McDermott, MD, in an accompanying editorial. The editorialists questioned whether the findings were generalizable to patients with mild PAD or those who are not hospitalized. However, they found the data consistent with previous studies suggesting that atherosclerosis is not homogeneous. “Differences in shear stress and hemodynamic forces among the femoral, coronary, and carotid arterial beds may also explain variability in associations of smoking and smoking cessation with the incidence of PAD versus myocardial infarction or stroke,” they said.
The findings also support the need to emphasize PAD in public health messages and provide an opportunity to educate patients about the risks of limb loss and impaired mobility associated with PAD, they said.
Many clinicians put a low priority on smoking cessation, the editorialists wrote, but “long-term tobacco abstinence is achievable using a chronic disease management approach resembling the strategies used to manage other risk factors,” they said. They cited the American College of Cardiology’s recently released “Expert Consensus Decision Pathway on Tobacco Cessation Treatment.” The pathway outlines advice for clinicians, including how to provide a brief intervention and resources along with advice to quit smoking.

Adjuvanted flu vaccine performs better than others in young children
according to an industry-funded synthesis of six studies.
The vaccine “offers significant advances over conventional inactivated influenza vaccines and presents an acceptable safety profile in children 6 months through 5 years of age,” Sanjay S. Patel, PhD, of Novartis Vaccines and Diagnostics, Cambridge, Mass., and associates wrote in the analysis, published in the International Journal of Infectious Diseases. “The noteworthy increases in antibody responses and decreases in influenza cases following vaccination suggest an alternative for use in a population that is heavily impacted by influenza disease.”
Children are, of course, vulnerable to flu. The Centers for Disease Control and Prevention reported that 186 children died of flu during the landmark 2017-2018 flu season. That’s the highest number of pediatric flu deaths since they became a notifiable condition in 2004 (exclusive of the 2009 pandemic, when 358 pediatric deaths were reported from April 15, 2009, to October 2, 2010).The CDC said the vaccine during that flu season had an overall effectiveness level of 40%. According to research of others, however, flu vaccines are less effective in younger children than in adolescents and adults (Vaccine. 2014;32[31]:3886-94; Cochrane Database Syst Rev. 2008. doi: 10.1002/14651858.CD004879.pub3).
Fluad – a MF59-adjuvanted inactivated trivalent seasonal influenza vaccine – is used in adults over 65 in the United States and 29 other countries, and it is approved for children aged 6 months through 23 months in Canada.
Dr. Patel and associates examined the results of six studies – one phase 1b, three phase 2, and two phase 3 – that tested Fluad with or without other vaccines in 11,942 children aged 6 months to 5 years. The studies, mostly multicenter, were conducted in various countries, mainly in Europe and South and Central America, from 2006 to 2012.
In general, children in the intervention groups in the studies received two doses of the Fluad vaccine 4 weeks apart: two 0.25-mL doses for children aged 6-35 months and two 0.5-mL doses for those aged 3 years or older. In most of the studies, parallel control groups received nonadjuvanted trivalent or quadrivalent influenza vaccines.
Most participants (93%-94%) completed the studies. Solicited adverse effects were common in all groups (72% in the Fluad group vs. 67% who received IIV3 vaccines), and generally mild to moderate and resolved in 1-3 days. Unsolicited adverse effects were similar (55% and 62%, respectively) in the two flu vaccine groups. The authors wrote that “these data reflect a safety profile consistent with other licensed inactivated influenza vaccines administered to children.”
As for results, Dr. Patel and colleagues said, “HI [hemagglutination inhibition] antibody responses to both homologous and heterologous influenza strains are higher following vaccination with aIIV3, and this increase in immunogenicity is observed across all age subgroups in children aged 6 months through 5 years, and most profound in the children 6 to 36 months.”
For example, in one of the phase 3 studies when the influenza viruses were antigenically matched (homologous) for A/H1N1 among the children aged 6-35 months seroconversion was 100% for allV3 (Fluad) and 38% for IIV3-1/IIV3-4 (trivalent/quadrivalent flu vaccines); among children aged 3-5 years seroconversion was 100% for allV3 and 82% for IIV3-1/IIV3-4. For AH3N2 homologous among children aged 6-35 months, seroconversion was 98% for allV3 and 44% for IIV3-1/IIV3-4. For the B strain homologous among children aged 6-35 months, seroconversion was 88% for allV3 and 19% for IIV3-1/IIV3-4; among children aged 3-5 years seroconversion for B was 99% for allV3 and 59% for IIV3-1/IIV3-4.
In the same study when the influenza viruses were antigenically mismatched (heterologous) for A/H1N1 among children of all ages 6 months to greater than 72 months, seroconversion was 96% for allV3 (Fluad) and 44% for IIV3-1/IIV3-4; for A/H3N2 it was 98% for allV3 and 49% for IIV3-1/IIV3-4, and for the B strain it was 10% for allV3 and 3% for IIV3-1/IIV3-4.
They added that “in addition, aIIV3 had the fastest onset of immunogenicity and longest persistence of immune response, which has implications for the real-world clinical setting, where the influenza season might start earlier than expected or last longer, and second (follow-up) vaccinations may be missed.”
Dr. Patel and associates said the MF59 adjuvant in Fluad “recruits immune cells (primarily monocytes, macrophages, neutrophils, and dendritic cells) at the site of injection and differentiates them into antigen-presenting cells. With an MF59-adjuvanted vaccine, more antigen is transported from the injection site to the draining lymph node, wherein MF59 leads to T-cell activation and an increased B-cell expansion and a greater number and diversity of antibodies.”
According to goodrx.com, one syringe of Fluad 0.5 mL costs $45-$74 with coupon. The same dose of Fluzone Quadrivalent, a flu vaccine recently approved by the Food and Drug Administration for use in young children aged 6-35 months, costs $31 with coupon.

according to an industry-funded synthesis of six studies.
The vaccine “offers significant advances over conventional inactivated influenza vaccines and presents an acceptable safety profile in children 6 months through 5 years of age,” Sanjay S. Patel, PhD, of Novartis Vaccines and Diagnostics, Cambridge, Mass., and associates wrote in the analysis, published in the International Journal of Infectious Diseases. “The noteworthy increases in antibody responses and decreases in influenza cases following vaccination suggest an alternative for use in a population that is heavily impacted by influenza disease.”
Children are, of course, vulnerable to flu. The Centers for Disease Control and Prevention reported that 186 children died of flu during the landmark 2017-2018 flu season. That’s the highest number of pediatric flu deaths since they became a notifiable condition in 2004 (exclusive of the 2009 pandemic, when 358 pediatric deaths were reported from April 15, 2009, to October 2, 2010).The CDC said the vaccine during that flu season had an overall effectiveness level of 40%. According to research of others, however, flu vaccines are less effective in younger children than in adolescents and adults (Vaccine. 2014;32[31]:3886-94; Cochrane Database Syst Rev. 2008. doi: 10.1002/14651858.CD004879.pub3).

Adjuvanted influenza vaccine appears safe for at-risk children
according to a study in the International Journal of Infectious Diseases.
Sanjay S. Patel, PhD, of Novartis Vaccines and Diagnostics, Cambridge, Mass., and colleagues performed a retrospective analysis on an integrated dataset that drew from six randomized clinical trials comparing aIIV3 with nonadjuvanted trivalent inactivated influenza vaccine (IIV3). The dataset comprised 10,794 patients aged 6 months through 5 years, of whom 373 (3%) were deemed at risk of influenza complications after review of their medical history for conditions such as heart disease, asthma, and endocrine disorders.
The rates of solicited adverse events (such as erythema, diarrhea, fever, and localized swelling) were 74% in the aIIV3 group and 73% in the IIV3 group. The rates for any unsolicited adverse events (such as upper respiratory tract infection) for aIIV3 and IIV3 were 54% and 59%, respectively (Int J Infect Dis. 2019. doi: 10.1016/j.ijid.2019.04.023).
One of the six studies included in the dataset randomized 2,655 children for immunogenicity analyses, of whom 103 (4%) were deemed at risk. Hemagglutination inhibition assay geometric mean titers against homologous A/H1N1, A/H3N2, and B strains 21 days after the second of two doses of vaccines were two to three times higher in the aIIV3 than in the IIV3 group, which suggests that aIIV3 is more immunogenic than IIV3. As the investigators noted, this is likely because the adjuvanted vaccine induces a greater magnitude of immune response to the vaccine, something already lower in children than in adults, as well as more breadth of response, meaning the response goes beyond strains included in the vaccines.
The small number of at-risk children in the study poses a limitation on its findings. Dr. Patel and associates said that, regardless, the results of immunogenicity analyses were strong. “Overall, this analysis indicates that aIIV3 has a similar safety profile in young children with underlying medical conditions, consistent with other licensed inactivated influenza vaccines.”
Novartis Vaccines and Diagnostics originally funded the study, but was later acquired by CSL Group and now operates as Seqirus, which continued funding for the study. The authors were employees of one or the other of these companies.
