Children with HIV benefit from double dose of PCV13 vaccine
, while children with kidney or lung disease may need only one dose, reported Sabelle Jallow, PhD, of the University of the Witwatersrand, Johannesburg, South Africa, and associates.
An open-label study was conducted at Chris Hani Baragwanath Academic Hospital (CHBAH) in Soweto, South Africa, to determine the immunogenicity of one and two doses of PCV13 in vaccine-naive children with HIV infection, kidney disease, or lung disease. Of the 112 children in the study, there were 50 HIV-infected children, 8 children with kidney disease, 9 with lung disease, and 45 HIV-uninfected control children with no chronic illness. The average age at enrollment was 62 months, 53% of participants were female, and 96% were of black African descent. At-risk children were given two doses of PCV13, 2 months apart, while control children received only one PCV13 dose (Vaccine. 2017. doi: 10.1016/j.vaccine.2017.06.081).
“In future studies, a larger spectrum of comorbidities should be included to determine the most cost-effective vaccination regimens particularly in low income countries,” the researchers noted.

Drug combo improves RV contractility in scleroderma-PAH
A combination of ambrisentan (Letairis) and tadalafil (Cialis) improves regional and global right ventricular contractility in patients with scleroderma-associated pulmonary arterial hypertension, according to an open-label investigation of 23 patients.
The project was a follow-up to a previous report showing that the upfront combination – tadalafil 40 mg and ambrisentan 10 mg oral once daily – improved hemodynamics, right ventricular (RV) structure and function, and functional status in treatment-naive patients after 36 weeks and “may represent a very effective therapy for this patient population” (Am J Respir Crit Care Med. 2015 Nov 1;192(9):1102-10).
At baseline, the subjects had normal left ventricular (LV) size and function, with borderline left atrial enlargement and mild LV diastolic dysfunction. Their right heart chambers were significantly dilated, with RV hypertrophy. Conventional RV function parameters – tricuspid annular systolic plane excursion (TAPSE) and fractional area change (FAC) – were impaired. RV systolic pressure (RVSP) was severely elevated. There was also a marked reduction of global RV longitudinal systolic strain (RVLSS), compared with normal values mainly because of a reduction in midventricular and apical RVLSS, with relative hyperkinesis of basal RVLSS
After 36 weeks of treatment, right heart chamber sizes were significantly reduced. There was also a decrease in RV free wall thickness, which coincided with a significant reduction in RV mass on cardiac MRI. TAPSE, FAC, and global RVLSS improved significantly, and RVSP decreased significantly. LV end-diastolic and end-systolic diameters and volumes increased significantly.
The changes “may represent transition from maladaptive RV remodeling ... to a more physiological and adaptive RV remodeling;” however, “the effects of treatment should be interpreted with caution, as this was an open-label study without a placebo or a single-drug control group,” said investigators led by Valentina Mercurio, MD, a postdoc fellow at Johns Hopkins University, Baltimore.
“It is conceivable that a heterogeneous RVLSS pattern exists in [scleroderma] patients with longitudinal hyperkinetic basal segment as the predominant vector of contraction early in the disease course. As PAH develops, the ability of the basal segment to compensate decreases, and RV failure ensues, suggesting a ‘two-hit’ hypothesis, in which a preexisting RV contractile dysfunction may predispose to further RV impairment when a second insult (PAH development) occurs,” they said.
Subjects were about 60 years old on average, and most were women. The majority shifted from World Health Organization PAH functional class 3 to 2 during the original trial. Mean 6 minute walk tests increased from 341 m to 401 m.
Gilead and United Therapeutics provided the ambrisentan and tadalafil. Dr. Mercurio reported funding from both companies and Merck. The original study was sponsored by United Therapeutics.

Algorithm for identifying IPF has low PPV
ICD-9 codes were poor at picking out idiopathic pulmonary fibrosis patients from administrative databases for epidemiologic studies, but a new tool could improve diagnostic accuracy, according to Kaiser Permanente and University of California, San Francisco (UCSF), investigators.
“In the age of large administrative databases and electronic medical records, there is rich opportunity to conduct population-based studies” of disease behavior, outcomes, health care use, and other matters, but researchers first need to be able to accurately identify patients with idiopathic pulmonary fibrosis (IPF) in large data sets, said investigators led by Brett Ley, MD, an assistant professor of medicine at UCSF.
The research community has traditionally relied on claims for specific IPF diagnostic codes – ICD-9 code 516.3 or ICD-9-CM code 516.31 – to identify patients, but the approach had never been validated. To see how well it works, the investigators applied it to the nearly 5.4 million adults in the Kaiser Permanente Northern California system during 2000-2014. After patients with interstitial lung disease-associated codes entered on or after the day of the last IPF code were excluded, the algorithm identified 2,608 patients as having IPF (Ann Am Thorac Soc. 2017 Jun;14[6]:880-7).
Next, the investigators randomly selected 150 of those patients and examined their medical records, procedure codes, CTs, and other patient-level data to see how many of them really had IPF. The results weren’t good. The positive predictive value of the IPF code-based algorithm was only 42.2%, with a sensitivity 55.6%.
The widely used code-based IPF algorithm does “not generate accurate estimates of IPF incidence and prevalence. ... Over half of the patients identified as having IPF ... did not have IPF on case review. Alarmingly, whereas half of the misclassified cases had an alternative [interstitial lung disease] diagnosis, the other half had no clinical or radiologic evidence of ILD [interstitial lung disease] at all.” The algorithm also “likely misses a substantial proportion of patients who do have IPF,” Dr. Ley and his colleagues said.
“We can only speculate about the reasons. ... It seems likely to be due to a combination of misdiagnosis at the clinical level and miscoding at the administrative level,” they said.
To try to improve the situation, the team tweaked the algorithm to include only patients 50 years or older who had at least two 516.3 or 516.31 claims 1 month or more apart and a chest CT procedure code beforehand. They again excluded ILD-associated claims on or after the day of the last IPF code.
Although the sensitivity of the modified algorithm was lower than the original, it had a more robust positive predictive value of 70.4% in the derivation cohort and 61.8% in the validation cohort, both derived from the 150 patients used to validate the original algorithm.
“By making a few simple, empirically derived changes to the IPF algorithm,” it’s possible to “more reliably identif[y] patients” with IPF. “We believe the modified IPF algorithm will be useful for population-based studies of IPF ... that require high diagnostic certainty,” the investigators concluded.
The traditional algorithm found an incidence of 6.8 cases per 100,000 person-years, which was on the low end of previous reports, perhaps because of the relative health and youth of the 5.4 million patient pool. As in past studies, IPF incidence increased with older age and was highest in white patients and men.
“Whether the more specific codes provided by the ICD-10 system will allow for improved case classification of IPF requires further study,” the investigators noted.
The work was funded by the National Institutes of Health. Dr. Ley reported speaker’s fees from Genentech, and one of the authors was an employee of the company. The senior author Harold Collard, MD, an associate professor in UCSF’s Division of Pulmonary and Critical Care Medicine, reported personal fees from Takeda, ImmuneWorks, Parexel, Pharma Capital Partners, and others.
This study glaringly displays potential problems with using ICD codes for research purposes and calls into question results from a handful of studies that yielded epidemiological estimates for idiopathic pulmonary fibrosis. We are reminded that practitioner-generated diagnostic codes of IPF recorded in the medical record are subject to inaccuracies, which can be illuminated by the “gold standard” – multidisciplinary adjudication.
Moving forward, particularly as longitudinal, nationwide IPF registries come online, patient-level case validation should be employed. As we move into the era of ICD-10, the study should serve as a call to improve IPF case ascertainment accuracy for any investigators choosing to use large data analytic strategies. Doing so will mute the background noise and allow us to better hear the signals of this complex disease.

Do sleep interventions prevent atrial fibrillation?
WASHINGTON – If patients have sleep disordered breathing with obstructive sleep apnea, will its treatment have cardiovascular disease benefits, especially in terms of the incidence or severity of atrial fibrillation?
Observational evidence suggests that apnea interventions may help these patients, but no clear case yet exists to prove that a breathing intervention works, experts say, and, as a result, U.S. practice is mixed when it comes to using treatment for obstructive sleep apnea (OSA), specifically continuous positive airway pressure (CPAP), to prevent or treat atrial fibrillation.
“Only a very small number of patients with atrial fibrillation undergo a sleep study,” he said in an interview. “Before I’d send my mother for atrial fibrillation ablation, I would first look for sleep disordered breathing [SDB],” but this generally isn’t happening routinely. Patients with other types of cardiovascular disease who could potentially benefit from sleep disordered breathing diagnosis and treatment are those with hypertension, especially patients who don’t fully respond to three or more antihypertensive drugs and patients with heart failure with preserved ejection fraction, he added.
Dr. Oldenburg also echoed Dr. Mehra in saying that the evidence supporting this approach for managing atrial fibrillation is less than conclusive.
“We need more precise phenotyping of patients” to better focus on patients with cardiovascular disease and sleep disordered breathing who clearly benefit from CPAP intervention, he said.
Results from the Sleep Apnea Cardiovascular Endpoints (SAVE) trial, reported in September 2016, especially tarnished the notion that treating sleep disordered breathing in patients with various cardiovascular diseases can help avoid future cardiovascular events. The multicenter trial enrolled 2,717 adults with moderate to severe obstructive sleep apnea and cardiovascular disease to receive either CPAP plus optimal routine care or optimal routine care only. After an average follow-up of close to 4 years, the patients treated with CPAP showed no benefit in terms of reduced cardiovascular events (N Engl J Med. 2016 Sept 8;375[10]:919-31).
An editorial that ran with this report suggested that the neutral outcome may have occurred because the average nightly duration of CPAP that patients in the trial self administered was just over 3 hours, arguably an inadequate dose. Other possible reasons for the lack of benefit include the time during their sleep cycle when patients administered CPAP (at the start of sleep rather than later) and that CPAP may have a reduced ability to avert new cardiovascular events in patients with established cardiovascular disease (N Engl J Med. 2016 Sept 8;375[8]:994-6).
Regardless of the reasons, the SAVE results, coupled with the neutral results and suggestion of harm from using adaptive servo-ventilation in patients with heart failure with reduced ejection fraction and central sleep apnea in the SERVE-HF trial (N Engl J Med. 2015 Sept 17;373[12]:1095-105), have thrust the management of SDB in patients with cardiovascular disease back to the point where SDB interventions have no well-proven indications for cardiovascular disease patients.
“With the SERVE-HF and SAVE trials not showing benefit, we now have equipoise” for using or not using SDB interventions in these patients, Dr. Mehra said. “It’s not clear that treating OSA improves outcomes. That allows us to randomize patients to a control placebo arm” in future trials.
An important issue in the failure to clearly establish a role for treating OSA in patients with atrial fibrillation or other cardiovascular diseases may have been over reliance on the apnea-hypopnea index (AHI) as the arbiter of OSA severity, Dr. Oldenburg said. “Maybe there are parameters to look at aside from AHI, perhaps hypoxemia burden or desaturation time. AHI is not the whole truth; we need to look at other parameters. AHI may not be the correct metric to look at in patients with various cardiovascular diseases.”
Her analysis also showed that patients with at least 10 minutes of sleep time with an oxygen saturation rate of 90% or less had a 64% increased rate of later atrial fibrillation hospitalizations, compared with those with fewer than 10 minutes spent in this state. Nearly a quarter of the patients studied fell into this category.
“Nocturnal oxygen desaturation may be stronger than AHI for predicting atrial fibrillation development,” Dr. Kendzerska concluded. “The severity of OSA-related intermittent hypoxia may be more important than sleep fragmentation in the development of atrial fibrillation. These findings support a relationship between OSA, chronic nocturnal hypoxemia, and new onset atrial fibrillation.”
However, using oxygen desaturation instead of AHI to gauge the severity of OSA won’t solve all the challenges that sleep researchers currently face in trying to determine the efficacy of breathing interventions to prevent or treat cardiovascular disease. In the neutral SAVE trial, researchers used nocturnal oxygen saturation levels to select patients with clinically meaningful OSA.
Dr. Mehra and Dr. Kendzerska had no disclosures. Dr. Oldenburg has received consultant fees, honoraria, and/or research support from ResMed, Respicardia, and Weinmann.

An editorial that ran with this report suggested that the neutral outcome may have occurred because the average nightly duration of CPAP that patients in the trial self administered was just over 3 hours, arguably an inadequate dose. Other possible reasons for the lack of benefit include the time during their sleep cycle when patients administered CPAP (at the start of sleep rather than later) and that CPAP may have a reduced ability to avert new cardiovascular events in patients with established cardiovascular disease (N Engl J Med. 2016 Sept 8;375[8]:994-6).
Regardless of the reasons, the SAVE results, coupled with the neutral results and suggestion of harm from using adaptive servo-ventilation in patients with heart failure with reduced ejection fraction and central sleep apnea in the SERVE-HF trial (N Engl J Med. 2015 Sept 17;373[12]:1095-105), have thrust the management of SDB in patients with cardiovascular disease back to the point where SDB interventions have no well-proven indications for cardiovascular disease patients.
“With the SERVE-HF and SAVE trials not showing benefit, we now have equipoise” for using or not using SDB interventions in these patients, Dr. Mehra said. “It’s not clear that treating OSA improves outcomes. That allows us to randomize patients to a control placebo arm” in future trials.
An important issue in the failure to clearly establish a role for treating OSA in patients with atrial fibrillation or other cardiovascular diseases may have been over reliance on the apnea-hypopnea index (AHI) as the arbiter of OSA severity, Dr. Oldenburg said. “Maybe there are parameters to look at aside from AHI, perhaps hypoxemia burden or desaturation time. AHI is not the whole truth; we need to look at other parameters. AHI may not be the correct metric to look at in patients with various cardiovascular diseases.”
Her analysis also showed that patients with at least 10 minutes of sleep time with an oxygen saturation rate of 90% or less had a 64% increased rate of later atrial fibrillation hospitalizations, compared with those with fewer than 10 minutes spent in this state. Nearly a quarter of the patients studied fell into this category.
“Nocturnal oxygen desaturation may be stronger than AHI for predicting atrial fibrillation development,” Dr. Kendzerska concluded. “The severity of OSA-related intermittent hypoxia may be more important than sleep fragmentation in the development of atrial fibrillation. These findings support a relationship between OSA, chronic nocturnal hypoxemia, and new onset atrial fibrillation.”
However, using oxygen desaturation instead of AHI to gauge the severity of OSA won’t solve all the challenges that sleep researchers currently face in trying to determine the efficacy of breathing interventions to prevent or treat cardiovascular disease. In the neutral SAVE trial, researchers used nocturnal oxygen saturation levels to select patients with clinically meaningful OSA.

WASHINGTON – If patients have sleep disordered breathing with obstructive sleep apnea, will its treatment have cardiovascular disease benefits, especially in terms of the incidence or severity of atrial fibrillation?
Observational evidence suggests that apnea interventions may help these patients, but no clear case yet exists to prove that a breathing intervention works, experts say, and, as a result, U.S. practice is mixed when it comes to using treatment for obstructive sleep apnea (OSA), specifically continuous positive airway pressure (CPAP), to prevent or treat atrial fibrillation.
“Only a very small number of patients with atrial fibrillation undergo a sleep study,” he said in an interview. “Before I’d send my mother for atrial fibrillation ablation, I would first look for sleep disordered breathing [SDB],” but this generally isn’t happening routinely. Patients with other types of cardiovascular disease who could potentially benefit from sleep disordered breathing diagnosis and treatment are those with hypertension, especially patients who don’t fully respond to three or more antihypertensive drugs and patients with heart failure with preserved ejection fraction, he added.
Dr. Oldenburg also echoed Dr. Mehra in saying that the evidence supporting this approach for managing atrial fibrillation is less than conclusive.
“We need more precise phenotyping of patients” to better focus on patients with cardiovascular disease and sleep disordered breathing who clearly benefit from CPAP intervention, he said.
Results from the Sleep Apnea Cardiovascular Endpoints (SAVE) trial, reported in September 2016, especially tarnished the notion that treating sleep disordered breathing in patients with various cardiovascular diseases can help avoid future cardiovascular events. The multicenter trial enrolled 2,717 adults with moderate to severe obstructive sleep apnea and cardiovascular disease to receive either CPAP plus optimal routine care or optimal routine care only. After an average follow-up of close to 4 years, the patients treated with CPAP showed no benefit in terms of reduced cardiovascular events (N Engl J Med. 2016 Sept 8;375[10]:919-31).

EXPERT ANALYSIS FROM ATS 2017
TB meningitis cases in U.S. are fewer but more complicated
BOSTON – The number of cases of meningitis caused by tuberculosis has fallen dramatically in the United States in recent decades as TB itself has become less common, according to findings from a study presented at the annual meeting of the American Academy of Neurology.
However, these findings from patient hospitalizations during 1993-2013 in the Nationwide Inpatient Sample database also indicate that neurologic complications from TB meningitis are on the rise.
The findings suggest that neurologists need to become involved whenever a patient with TB shows signs of neurologic problems, said study lead author Alexander E. Merkler, MD, of Cornell University, New York, in an interview. “They’re at high risk, and some complications can be life threatening.”
According to Dr. Merkler, TB meningitis occurs when a patient’s case of TB invades the meninges surrounding the brain. “It can lead to seizures, stroke, hydrocephalus, and death,” he said at the meeting.
TB meningitis can affect anyone with TB, he said, but those who are immunocompromised and those with diabetes are especially vulnerable.
For their current study, Dr. Merkler and his associates used the Nationwide Inpatient Sample database to track patients hospitalized in the United States with TB meningitis from 1993 to 2013. They found 16,196 new cases over the 20-year period and uncovered a dramatic decrease in the rate of hospitalizations: The incidence fell from 6.2 to 1.9 hospitalizations per million people (rate difference, 4.3; 95% confidence interval, 2.1-6.5; P less than .001), and mortality during index hospitalization fell from 17.6% (95% CI, 12.0%-23.2%) to 7.6%, (95% CI, 2.2%-13.0%).
Dr. Merkler said that mortality appears to have declined as TB itself has become less common. According to the Centers for Disease Control and Prevention, the number of reported TB cases nationally was 9,557 in 2015, a rate of 3.0 cases per 100,000 persons. The total number of annual cases fell each year from 1993 to 2014, the CDC reported, although the rate leveled off at around 3.0/100,000 from 2013 to 2015.
“The fewer people have lung TB, the less they’ll have it going into meningitis and the brain,” Dr. Merkler said. “In terms of mortality, it is going down because we have better supportive care. We’re better at keeping these patients alive and giving them antibiotics sooner.”
However, the study found that the rates of the following complications in hospitalized TB meningitis patients rose over the 20-year period:
• Hydrocephalus, from 2.3% (95% confidence interval, 0.5%-4.2%) to 5.4% (95% CI, 2.3%-10.0%).
• Seizure, from 2.9% (95% CI, 0.3%-5.4%) to 14.1% (95% CI, 7.3%-21.0%).
• Stroke, from 2.9% (95% CI, 0.6%-5.3%) to 13.0% (95% CI, 6.3%-19.8%).
• Vision and hearing impairment, from 8.2% (95% CI, 4.8%-11.6%) to 10.9% (95% CI, 4.1%-17.6%), and from 1.1% (95% CI, 0.0%-2.3%) to 3.3% (95% CI, 0.0%-6.9%), respectively.
Dr. Merkler said it’s not clear why these rates are going up, but it may be because patients have more complications as a result of living longer. Another theory is that a form of drug-resistant TB is boosting the level of these complications, Dr. Merkler said, but he’s skeptical of that idea: “I don’t know why drug resistance would lead to more neurological complications.”
The study was funded by the National Institute of Neurological Disorders and Stroke and the Michael Goldberg Stroke Research Fund. Dr. Merkler reported no relevant financial disclosures.

Nurses help more rheumatic disease patients get vaccinated
MADRID – A nurse-led program successfully increased the uptake of pneumococcal vaccination among patients with chronic inflammatory rheumatic diseases in a single-center study.
From the start to the end of a 4-month evaluation period, the rate of vaccination of at-risk patients increased from 17.1% (13/76) to 77.6% (59/76; P less than .001).
It is well known that patients with inflammatory rheumatic diseases, such as systemic lupus erythematous (SLE) and systemic vasculitis, are at high risk for contracting pneumococcal disease, reported Tiphaine Goulenok, MD, of Bichat Hospital, Paris, at the European Congress of Rheumatology. This is particularly the case if they are receiving immunosuppressive treatments.
Although French national guidelines were introduced in 2011 that recommend that such patients routinely receive pneumococcal vaccination, the vaccination rate is often lower than is desirable, Dr. Goulenok observed at a press briefing. Her prior research suggests that only 16.2% of patients with an indication for the PCV13 vaccine actually received it.
In the current study, 126 patients with inflammatory rheumatic diseases were consecutively recruited and seen at the day unit of Bichat Hospital. Of these patients, 76 were candidates for pneumococcal vaccination because they were receiving steroids or other immunosuppressive drugs. Of these patients, 13 were already vaccinated, and, of the 63 who were not, nurses correctly identified 56 (88.9%) who needed to be vaccinated, of whom 46 agreed and 10 refused.
“We found a low rate of pneumococcal vaccination among patients,” said Dr. Goulenok, “but, thanks to high screening by the nurses, vaccination coverage was increased and the nurse-led vaccination program was very efficient”.
Robert Landewé, MD, who chaired the press briefing, observed that, despite being in an “era of guidelines,” ways of successfully implementing them in practice remained a challenge. The nurse-led program appeared to be one way to increase pneumococcal vaccination uptake, but perhaps other ways need to be sought, especially as there may be substantial resistance to vaccination among patients, he said.
“Patients are sometimes more afraid of the consequences of vaccination than [of] the disease that is prevented by vaccination,” said Dr. Landewé, who is professor of rheumatology at the Academic Medical Center in Amsterdam (the Netherlands).
Dr. Goulenok and Dr. Landewé reported no disclosures.

FDA approves betrixaban for VTE prophylaxis
Betrixaban, a factor Xa inhibitor, has been approved for the prophylaxis of venous thromboembolism (VTE) in at-risk adult patients hospitalized with an acute illness, according to an announcement from the Food and Drug Administration.
Approval was based on results from a randomized, double-blind clinical trial in which over 7,000 hospitalized patients at risk for VTE received either extended-duration betrixaban (35-42 days) or short duration enoxaparin (6-14 days), a low molecular weight heparin administered subcutaneously. The rate of deep vein thrombosis, nonfatal pulmonary embolism, or VTE-related death was 4.4% among patients receiving betrixaban and 6% among patients receiving enoxaparin (relative risk, 0.75; 95% confidence interval: 0.61, 0.91).
The recommended dosage for betrixaban is 80 mg per day for 35-42 days at the same time every day with food, after a dose of 160 mg on the first day of treatment.
Betrixaban will be marketed as Bevyxxa by Portola.

ACIP approves new influenza vaccine recommendations
FROM AN ACIP MEETING
by the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) after a lengthy debate over specifics regarding recommendations for pregnant women.
The proposed recommendation that sparked the debate would change the wording of the previous recommendation for pregnant women to receive a seasonal inactivated vaccine (IIV) to “any licensed, recommended, and age-appropriate, trivalent or quadrivalent IIV or RIV [recombinant influenza vaccine] may be used.”
“I think there’s a subtle, but important difference here between making what would appear to be an affirmative statement that RIV is safe in pregnant women, versus just staying silent on it, and saying ‘we’re not saying you shouldn’t use it, but we don’t have enough data to affirmatively say it is safe,’ ” said Cindy Pellegrini, senior vice president of Public Policy and Government Affairs at the March of Dimes Foundation.
In response, members of the committee pointed out that the responsibility of determining safety lies with the Food and Drug Administration, which has already licensed the Flublok trivalent vaccine with expectations that the quadrivalent vaccine soon will follow.
While Lisa Grohskopf, MD, MPH, medical officer of the influenza division of the CDC, did acknowledge that there were more data on the safety of inactivated influenza vaccines, she asserted to the committee that “the general overall safety profile of Flublok in comparison to inactivated vaccines is reassuring.”
“For example, one concern that arises is reactogenicity and inflammation. [In terms of] overall reactogenicity in the studies where Flublok and inactivated vaccines have been compared, rates of the adverse and systemic reactions were similar,” Dr. Grohskopf said.
A motion was made to change the wording of the recommendation; however, the motion was not passed, and the eventual vote on the approval was conducted.
The ACIP also voted unanimously to change the safe age limit noted in influenza guidelines for use of Afluria (IIV3) from 9 years and older to 5 years and older. A footnote saying that the ACIP recommends Afluria for children 9 years and older will be removed.
This change, which mirrors the licensing Afluria has with the FDA, was based on research conducted by Seqirus that showed fever levels were the same for Afluria trivalent and quadrivalent vaccines in children 5 to 9 years old, both of which were less than historical vaccine rates.
The approved recommendations will be sent to the director of the CDC and the U.S. Department of Health and Human Services. Once reviewed and approved, the final recommendations will be published in the CDC’s Morbidity and Mortality Weekly Report. The committee members had no relevant financial disclosures.

FROM AN ACIP MEETING
by the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) after a lengthy debate over specifics regarding recommendations for pregnant women.
The proposed recommendation that sparked the debate would change the wording of the previous recommendation for pregnant women to receive a seasonal inactivated vaccine (IIV) to “any licensed, recommended, and age-appropriate, trivalent or quadrivalent IIV or RIV [recombinant influenza vaccine] may be used.”
“I think there’s a subtle, but important difference here between making what would appear to be an affirmative statement that RIV is safe in pregnant women, versus just staying silent on it, and saying ‘we’re not saying you shouldn’t use it, but we don’t have enough data to affirmatively say it is safe,’ ” said Cindy Pellegrini, senior vice president of Public Policy and Government Affairs at the March of Dimes Foundation.
In response, members of the committee pointed out that the responsibility of determining safety lies with the Food and Drug Administration, which has already licensed the Flublok trivalent vaccine with expectations that the quadrivalent vaccine soon will follow.
While Lisa Grohskopf, MD, MPH, medical officer of the influenza division of the CDC, did acknowledge that there were more data on the safety of inactivated influenza vaccines, she asserted to the committee that “the general overall safety profile of Flublok in comparison to inactivated vaccines is reassuring.”

Tipoffs that an infant hospitalized with pertussis may require ICU
MADRID – Infants hospitalized for pertussis are more likely to develop severe disease requiring pediatric ICU admission if they are experiencing apnea, are unvaccinated against pertussis, or are less than 2 months old, Maria Arranz, MD, reported at the annual meeting of the European Society for Paediatric Infectious Diseases.
“The presence of these parameters on admission should warn us of possible severe disease,” said Dr. Arranz of Gregorio Maranon Hospital in Madrid.
Dr. Arranz presented a retrospective observational study of 101 children under 1 year of age who were hospitalized for pertussis at the Madrid tertiary center prior to the hospital’s 2016 shift to a strategy of maternal immunization during pregnancy as a means of preventing pertussis in infancy. Thirteen percent of the children required admission to the pediatric ICU and thus by definition had severe disease.
Half of infants in the study were not vaccinated against pertussis. That proved to be a powerful risk factor for severe disease requiring an ICU stay. Only 8% of children with severe pertussis were vaccinated, compared with a 58% vaccination rate among those who avoided the ICU.
Apneic pauses were noted in 67% of the severe disease group, compared with 28% of the infants who didn’t need the ICU.
The pertussis patients admitted to the pediatric ICU averaged 1 month of age, compared with age 2 months in the nonsevere group.
The maximum leukocyte, lymphocyte, and neutrophil counts during the hospital stay of the severe disease group averaged 23,600 cells/mm3, 18,000/mm3, and 5,000/mm3, respectively, significantly greater than the 15,300, 10,700, and 3,900 cells/mm3 in infants who did not require the ICU. Levels of all three cells also were higher at admission in the severe pertussis group than in those who didn’t make it to the ICU, albeit not statistically significantly so.
Dr. Arranz reported having no financial conflicts of interest regarding her study.

AT ESPID 2017
Key clinical point:
Major finding: Among infants hospitalized for pertussis, apneic pauses were present in two-thirds of those with severe disease, ultimately resulting in admission to the pediatric ICU, compared with 28% of those who didn’t require an ICU stay.
Data source: This retrospective observational study sought to identify factors associated with severe pertussis requiring an ICU stay in a group of 101 Spanish infants hospitalized with the disease.
Disclosures: The presenter reported having no financial conflicts of interest regarding her study.
MMR vaccine cut hospitalizations for unrelated respiratory infections
, said Giuseppe La Torre of the Sapienza University of Rome and his associates.
The 2-year retrospective database study included 11,004 children, 21% of whom did not receive the MMR vaccine; 49% received one dose, and 30% received two doses. There were 12 hospitalizations for measles (9 in unvaccinated children, 3 in those who received one dose, and none in those who received two doses), 2 hospitalizations for mumps (1 among vaccinated and 1 among unvaccinated children), and no hospitalizations for rubella (P less than .001).
There were 414 hospitalizations for all infectious diseases, 11% in unvaccinated children, 1.5% in those who had received one dose of vaccine, and 1% in those who had received two doses (P less than .001). MMR vaccine also was highly protective against hospitalizations for all infectious diseases (HR, 0.29).
Of 809 hospitalizations for respiratory diseases, 18% involved children who had not been vaccinated, 4% involved children who had received one dose, and 5.5% involved children vaccinated with two doses (P less than .001). MMR likewise was highly protective against hospitalizations for respiratory diseases (HR, 0.18).
