Dried blood spot testing showed sensitivity comparable to saliva as a screening method for congenital cytomegalovirus infection in newborns, based on data from more than 12,000 newborns.

Congenital cytomegalovirus (cCMV) is a common congenital virus in the United States, but remains underrecognized, wrote Sheila C. Dollard, PhD, of the Centers for Disease Control and Prevention in Atlanta, and colleagues.

“Given the burden associated with cCMV and the proven benefits of treatment and early intervention for some affected infants, there has been growing interest in universal newborn screening,” but an ideal screening strategy has yet to be determined, they said.

In a population-based cohort study published in JAMA Pediatrics, the researchers screened 12,554 newborns in Minnesota, including 56 with confirmed CMV infection. The newborns were screened for cCMV via dried blood spots (DBS) and saliva collected 1-2 days after birth. The DBS were tested for CMV DNA via polymerase chain reaction (PCR) at the University of Minnesota (UMN) and the CDC.

The overall sensitivity rate was 85.7% for a combination of laboratory results from the UMN and the CDC, which had separate sensitivities of 73.2% and 76.8%, respectively.

The specificity of the combined results was 100.0% (100% from both UMN and CDC), the combined positive predictive value was 98.0% (100.0% from UMN, 97.7% from CDC), and the combined negative predictive value was 99.9% (99.9% from both UMN and CDC).

By comparison, saliva swab test results showed sensitivity of 92.9%, specificity of 99.9%, positive predictive value of 86.7%, and negative predictive value of 100.0%.

The study findings were limited by several factors including the false-positive and false-negative results from saliva screening. Overall, the false-positive rate was 0.06%, which is comparable to rates from other screening techniques, the researchers said. “The recent Food and Drug Administration approval of a point-of-care neonatal saliva CMV test (Meridian Bioscience), underscores the importance of further clarifying the role of false-positive saliva CMV test results and underscores the requirement for urine confirmation for diagnosis of cCMV,” they added.

However, the study findings support the acceptability and feasibility of cCMV screening, as parents reported generally positive attitudes about the process, the researchers said.

The study is ongoing, and designed to follow infants with confirmed cCMV for up to age 4 years to assess clinical outcomes, they added. “Diagnostic methods are always improving, and therefore, our results show the potential of DBS to provide low-cost CMV screening with smooth integration of sample collection, laboratory testing, and follow-up,” they concluded.
 

Findings lay foundation for widespread use

“By using enhanced PCR methods, Dollard et al. have rekindled the hope that NBDBS [newborn dried blood spots] testing may be a viable method for large-scale, universal newborn screening for congenital CMV,” Gail J. Demmler-Harrison, MD, of Texas Children’s Hospital, Houston, wrote in an accompanying editorial. Congenital CMV is a common infection, but accurate prevalence remains uncertain because not all newborns are tested, she noted. Detection of CMV currently may involve urine, saliva, and blood, but challenges to the use of these methods include “a variety of constantly evolving DNA detection methods,” she said.

Although urine and saliva samples have been proposed for universal screening, they would require the creation of new sample collection and testing programs. “The routine of collecting the NBDBS samples on all newborns and the logistics of routing them to central laboratories and then reporting results to caregivers is already in place and are strengths of NBDBS samples for universal newborn screening,” but had been limited by a less sensitive platform than urine or saliva, said Dr. Demmler-Harrison.

“The results in the study by Dollard et al. may be a total game changer for the NBDBS proponents,” she emphasized. “Furthermore, scientists who have adapted even more sensitive DNA detection assays, such as the loop-mediated isothermal assay for detection of DNA in clinical samples from newborns, may be able to adapt loop-mediated isothermal assay methodology to detect CMV DNA in NBDBS,” she added.

“By adapting the collection methods, by using optimal filter paper to enhance DNA adherence, by improving DNA elution procedures, and by developing novel amplification and detection methods, NBDBS may soon meet the challenge and reach the sensitivity and specificity necessary for universal screening for congenital CMV,” she concluded.

The study was supported by the CDC, the Minnesota Department of Health, the National Vaccine Program Office (U.S. federal government), and the University of South Carolina Disability Research and Dissemination Center.

Dr. Dollard and Dr. Demmler-Harrison had no financial conflicts to disclose.

The proportion of family physicians providing care to children from 2017 to 2018 has dropped again, according to new research.

This the latest sign of a long-term decline, and it “poses a broader concern for a specialty that defines itself by its comprehensive scope of practice,” said the study investigators of the Robert Graham Center in Washington, D.C., in a written statement. “This is consistent with previous Robert Graham Center research that reported a similar steady decline from 1992 to 2002.”

Self-reported data from family physicians indicate that 84.3% cared for children aged 18 years and under in 2017, compared with 83.0% in 2018, based on a cross-sectional analysis of data gathered from 11,674 family physicians who completed the practice demographic questionnaire attached to the American Board of Family Medicine’s certification exam in 2017 and 2018.

“This current trend is unsettling, because family physicians provide the majority of pediatric care in rural and pediatrically underserved areas of the United States,” study author Anuradha Jetty, MPH, and coauthors said in the statement.

The analysis also offers a snapshot of the current state of pediatric care offered by family physicians. In 2017 and 2018, FPs were more likely to see patients aged 5-18 years than those under age 5 (83.0% vs. 67.0%), with variation by age, location, and race/ethnicity, said Ms. Jetty and colleagues, in their new paper.

FPs aged 60 years and older were much less likely to see pediatric patients, compared with those under age 40: odds ratios were 0.52 for children under 5 and 0.56 for children 5-18. Regional variation was even more pronounced: Compared with their colleagues in the Southern states, Midwestern FPs were 1.52 times as likely to treat children aged 5-18 and 2.52 times as likely to treat children under age 5, the investigators reported.

Non-Hispanic Asian and Hispanic family physicians had significantly lower odds of seeing pediatric patients, relative to non-Hispanic White family physicians, as did FPs who were international medical graduates (OR, 0.74), compared with those who trained in the United States, they said.

“Female gender was associated with seeing pediatric patients in a prior study using 2006-2009 [American Board of Family Medicine] data; however, we found no such association in 2017-2018,” Ms. Jetty and associates noted.

“Many diverse drivers likely influence the findings we observed, including organizational, personal, social, and economic factors,” they wrote, suggesting that the policies of some HMOs “may limit scope of practice for employed physicians,” while those who practice in areas of low pediatrician density might “capitalize on a market opportunity ... more than physicians in pediatrician-saturated areas with greater competition for young patients.”

The overall shortage of primary pediatric care may be a matter of debate, the investigators said, but “there is undoubtedly significant variability in the regional supply of pediatric primary care physicians and thus areas where family physicians are needed to meet current pediatric workforce demand.”

New COVID-19 cases in children continue to drop each week, but the total number of cases has now surpassed 3 million since the start of the pandemic, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

There were just over 99,000 new cases reported during the week of Feb. 5-11, the lowest number since early November and the fourth consecutive week with a decline. It was still enough, though, to bring the total to 3.03 million children infected with SARS-CoV-19 in the United States, the AAP and the CHA said in their weekly report.

The nation also hit a couple of other ignominious milestones. The cumulative rate of COVID-19 infection now stands at 4,030 per 100,000, so 4% of all children have been infected. Also, children represented 16.9% of all new cases for the week, which equals the highest proportion seen throughout the pandemic, based on data from health departments in 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

There have been 241 COVID-19–related deaths in children so far, with 14 reported during the week of Feb. 5-11. Kansas just recorded its first pediatric death, which leaves 10 states that have had no fatalities. Texas, with 39 deaths, has had more than any other state, among the 43 that are reporting mortality by age, the AAP/CHA report showed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A Zika virus vaccine candidate prompted antibody responses in 80% of individuals who received two doses in a phase 1 study.

Although Zika cases have declined in recent years, “geographic expansion of the Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” wrote Nadine C. Salisch, PhD, of Janssen Vaccines and Prevention, Leiden, the Netherlands, and colleagues in a paper published in Annals of Internal Medicine.

No vaccine against Zika is yet available, although more than 10 candidates have been studied in preclinical trials to date, they said.

The researchers randomized 100 healthy adult volunteers to an experimental Zika vaccine candidate known as Ad26.ZIKV.001 in either one-dose or two-dose regimens of 5x10¹⁰ viral particles (low dose) or 1x10¹¹ viral particles (high dose) or placebo. Approximately half (55%) of the participants were women, and 72% were White.

Approximately 80% of patients in both two-dose groups showed antibody responses for a year after vaccination. Geometric mean titers (GMTs) reached peak of 823.4 in the low-dose/low-dose group and 961.5 in the high-dose/high-dose group. At day 365, the GMTs for these groups were 68.7 and 87.0, respectively.

A single high-dose vaccine achieved a similar level of neutralizing antibody titers, but lower peak neutralizing responses than the two-dose strategies, the researchers noted.

Most of the reported adverse events were mild to moderate, and short lived; the most common were injection site pain or tenderness, headache, and fatigue, the researchers said. After the first vaccination, 75% of participants in the low-dose groups, 88% of participants in high-dose groups, and 45% of participants receiving placebo reported local adverse events. In addition, 73%, 83%, and 40% of the participants in the low-dose, high-dose, and placebo groups, respectively, reported systemic adverse events. Reports were similar after the second vaccination. Two serious adverse events not related to vaccination were reported; one case of right lower lobe pneumonia and one case of incomplete spontaneous abortion.

The researchers also explored protective efficacy through a nonlethal mouse challenge model. “Transfer of 6 mg of IgG from Ad26.ZIKV.001 vaccines conferred complete protection from viremia in most recipient animals, with statistically significantly decreased breakthrough rates and cumulative viral loads per group compared with placebo,” they said.

The study findings were limited by the inability to assess safety and immunogenicity in an endemic area, the researchers noted. However, “Ad26.ZIKV.001 induces potent ZIKV-specific neutralizing responses with durability of at least 1 year, which supports further clinical development if an unmet medical need reemerges,” they said. “In addition, these data underscore the performance of the Ad26 vaccine platform, which Janssen is using for different infectious diseases, including COVID-19,” they noted.
 

Ad26 vector platform shows consistency

“Development of the investigational Janssen Zika vaccine candidate was initiated in 2015, and while the incidence of Zika virus has declined since the 2015-2016 outbreak, spread of the ‘carrier’ Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” lead author Dr. Salisch said in an interview. For this reason, researchers say the vaccine warrants further development should the need reemerge, she said.

“Our research has found that while a single higher-dose regimen had lower peak neutralizing responses than a two-dose regimen, it achieved a similar level of neutralizing antibody responses at 1 year, an encouraging finding that shows our vaccine may be a useful tool to curb Zika epidemics,” Dr. Salisch noted. “Previous experience with the Ad26 vector platform across our investigational vaccine programs have yielded similarly promising results, most recently with our investigational Janssen COVID-19 vaccine program, for which phase 3 data show a single-dose vaccine met all primary and key secondary endpoints,” she said.

“The biggest barrier [to further development of the candidate vaccine] is one that we actually consider ourselves fortunate to have: The very low incidence of reported Zika cases currently reported worldwide,” Dr. Salisch said. “However, the current Zika case rate can change at any time, and in the event the situation demands it, we are open to alternative regulatory pathways to help us glean the necessary insights on vaccine safety and efficacy to further advance the development of this candidate,” she emphasized.

As for additional research, “there are still questions surrounding Zika transmission and the pathomechanism of congenital Zika syndrome,” said Dr. Salisch. “Our hope is that a correlate of protection against Zika disease, and in particular against congenital Zika syndrome, can be identified,” she said.  

Consider pregnant women in next phase of research

“A major hurdle in ZIKV vaccine development is the inability to conduct large efficacy studies in the absence of a current outbreak,” Ann Chahroudi, MD, of Emory University, Atlanta, and Sallie Permar, MD, of Weill Cornell Medicine, New York, wrote in an accompanying editorial.

The current study provided some efficacy data using a mouse model, but “these data are obviously not conclusive for human protection,” they said.

“A further challenge for ZIKV vaccine efficacy trials will be to demonstrate fetal protection from [congenital Zika syndrome] after adult immunization. There should be a clear plan to readily deploy phase 3 trials for the most promising vaccines to emerge from phase 1 and 2 in the event of an outbreak, as was implemented for Ebola, including infant follow-up,” they emphasized.

The editorialists noted that the study did not include pregnant women, who represent a major target for immunization, but they said that vaccination of pregnant women against other neonatal pathogens such as influenza and tetanus has been effective. “Candidate ZIKV vaccines proven safe in phase 1 trials should immediately be assessed for safety and efficacy in pregnant women,” they said. Although Zika infections are not at epidemic levels currently, resurgence remains a possibility and the coronavirus pandemic “has taught us that preparedness for emerging infections is crucial,” they said.
 

Zika vaccine research is a challenge worth pursuing

“It is important to continue Zika vaccine research because of the unpredictable nature of that infection,” Kevin Ault, MD, of the University of Kansas, Kansas City, said in an interview. “Several times Zika has gained a foothold in unexposed and vulnerable populations,” Dr. Ault said.  “Additionally, there are some data about using this vector during pregnancy, and eventually this vaccine may prevent the birth defects associated with Zika infections during pregnancy, he noted.

Dr. Ault said he was not surprised by the study findings. “This is a promising early phase vaccine candidate, and this adenovirus vector has been used in other similar trials,” he said. Potential barriers to vaccine development include the challenge of conducting late phase clinical trials in pregnant women, he noted. “The relevant endpoint is going to be clinical disease, and one of the most critical populations is pregnant women,” he said. In addition, “later phase 3 trials would be conducted in a population where there is an ongoing Zika outbreak,” Dr. Ault emphasized.   

The study was supported by Janssen Vaccines and Infectious Diseases.

As for additional research, “there are still questions surrounding Zika transmission and the pathomechanism of congenital Zika syndrome,” said Dr. Salisch. “Our hope is that a correlate of protection against Zika disease, and in particular against congenital Zika syndrome, can be identified,” she said.  

Consider pregnant women in next phase of research

“A major hurdle in ZIKV vaccine development is the inability to conduct large efficacy studies in the absence of a current outbreak,” Ann Chahroudi, MD, of Emory University, Atlanta, and Sallie Permar, MD, of Weill Cornell Medicine, New York, wrote in an accompanying editorial.

The current study provided some efficacy data using a mouse model, but “these data are obviously not conclusive for human protection,” they said.

“A further challenge for ZIKV vaccine efficacy trials will be to demonstrate fetal protection from [congenital Zika syndrome] after adult immunization. There should be a clear plan to readily deploy phase 3 trials for the most promising vaccines to emerge from phase 1 and 2 in the event of an outbreak, as was implemented for Ebola, including infant follow-up,” they emphasized.

The editorialists noted that the study did not include pregnant women, who represent a major target for immunization, but they said that vaccination of pregnant women against other neonatal pathogens such as influenza and tetanus has been effective. “Candidate ZIKV vaccines proven safe in phase 1 trials should immediately be assessed for safety and efficacy in pregnant women,” they said. Although Zika infections are not at epidemic levels currently, resurgence remains a possibility and the coronavirus pandemic “has taught us that preparedness for emerging infections is crucial,” they said.
 

Zika vaccine research is a challenge worth pursuing

“It is important to continue Zika vaccine research because of the unpredictable nature of that infection,” Kevin Ault, MD, of the University of Kansas, Kansas City, said in an interview. “Several times Zika has gained a foothold in unexposed and vulnerable populations,” Dr. Ault said.  “Additionally, there are some data about using this vector during pregnancy, and eventually this vaccine may prevent the birth defects associated with Zika infections during pregnancy, he noted.

Dr. Ault said he was not surprised by the study findings. “This is a promising early phase vaccine candidate, and this adenovirus vector has been used in other similar trials,” he said. Potential barriers to vaccine development include the challenge of conducting late phase clinical trials in pregnant women, he noted. “The relevant endpoint is going to be clinical disease, and one of the most critical populations is pregnant women,” he said. In addition, “later phase 3 trials would be conducted in a population where there is an ongoing Zika outbreak,” Dr. Ault emphasized.   

The study was supported by Janssen Vaccines and Infectious Diseases.

Dr. Chahroudi had no financial conflicts to disclose. Dr. Permar disclosed grants from Merck and Moderna unrelated to the current study. Dr. Ault had no relevant financial conflicts to disclose; he has served as an adviser to the Centers for Disease Control and Prevention, the World Medical Association, the National Vaccine Program Office, and the National Institute for Allergy and Infectious Diseases.

It is well established that LGBTQ individuals experience more health disparities compared with their cisgender, heterosexual counterparts. In general, LGBTQ adolescents and young adults have higher levels of depression, suicide attempts, and substance use than those of their heterosexual peers. However, a key protective factor is family acceptance and support. By encouraging families to modify and change behaviors that are experienced by their LGBTQ children as rejecting and to engage in supportive and affirming behaviors, providers can help families to decrease risk and promote healthy outcomes for LGBTQ youth and young adults.

To reduce risk, pediatricians should ask LGBTQ patients about family rejecting behaviors and help parents and caregivers to identify and understand the effect of such behaviors to reduce health risks and conflict that can lead to running away, expulsion, and removal from the home. Even decreasing rejecting behaviors to moderate levels can significantly improve negative outcomes.⁵

Caitlin Ryan, PhD, and her team also identified and measured more than 50 family accepting behaviors that help protect against risk and promote well-being. They found that young adults who experience high levels of family acceptance during adolescence report significantly higher levels of self-esteem, social support, and general health with much lower levels of depression, suicidality, and substance abuse.⁷ Family accepting and supportive behaviors include talking with the child about their LGBTQ identity; advocating for their LGBTQ child when others mistreat them; requiring other family members to treat their LGBTQ child with respect; and supporting their child’s gender identity.⁵ FAP has developed an evidence-informed family support model and multilingual educational resources for families, providers, youth and religious leaders to decrease rejection and increase family support. These are available in print copies and for download at familyproject.sfsu.edu.

In addition, Dr. Ryan and colleagues^1,4,8 recommend the following guidance for providers:

• Ask LGBTQ adolescents about family reactions to their sexual orientation, gender identity, and expression, and refer to LGBTQ community support programs and for supportive counseling, as needed.
• Identify LGBTQ community support programs and online resources to educate parents about how to help their children. Parents need culturally relevant peer support to help decrease rejection and increase family support.
• Advise parents that negative reactions to their adolescent’s LGBTQ identity may negatively impact their child’s health and mental health while supportive and affirming reactions promote well-being.
• Advise parents and caregivers to modify and change family rejecting behaviors that increase their child’s risk for suicide, depression, substance abuse ,and risky sexual behaviors.
• Expand anticipatory guidance to include information on the need for support and the link between family rejection and negative health problems.
• Provide guidance on sexual orientation and gender identity as part of normative child development during well-baby and early childhood care.
• Use FAP’s multilingual family education booklets and Healthy Futures poster series in family and patient education and provide these materials in clinical and community settings. FAP’s Healthy Futures posters include a poster guidance, a version on family acceptance, a version on family rejection and a family acceptance version for conservative families and settings. They are available in camera-ready art in four sizes in English and Spanish and are forthcoming in five Asian languages: familyproject.sfsu.edu/poster.

“What kind of parent are you? Why don’t you straighten him out!” rants the woman being jostled in the grocery store by your patient. “Easy for you to say,” thinks your patient’s frazzled and now insulted parent.

Blaming the parent for an out-of-control child has historically been a common refrain of neighbors, relatives, and even strangers. But considering child behavior as resulting from both parent and child factors is central to the current transactional model of child development. In this model, mismatch of the parent’s and child’s response patterns is seen as setting them up for chronically rough interactions around parent requests/demands. A parent escalating quickly from a briefly stated request to a tirade may create more tension paired with an anxious child who takes time to act, for example. Once a parent (and ultimately the child) recognize patterns in what leads to conflict, they can become more proactive in predicting and negotiating these situations. Ross Greene, PhD, explains this in his book “The Explosive Child,” calling the method Collaborative Problem Solving (now Collaborative & Proactive Solutions or CPS).

While there are general principles parents can use to modify what they consider “mis”behaviors, these methods often do not account for the “missing” skills of the individual child (and parent) predisposing to those “mis”takes. Thinking of misbehaviors as being because of a kind of “learning disability” in the child rather than willful defiance can help cool off interactions by instead focusing on solving the underlying problem.

What kinds of “gaps in skills” set a child up for defiant or explosive reactions? If you think about what features of children, and parent-child relationships are associated with harmonious interactions this becomes evident. Children over 3 who are patient, easygoing, flexible or adaptable, and good at transitions and problem-solving can delay gratification and tolerate frustration, regulate their emotions, explain their desires, and multitask. They are better at reading the parent’s needs and intent and tend to interpret requests as positive or at least neutral and are more likely to comply with parent requests without a fuss.

What? No kid you know is great at all of these? These skills, at best variable, develop with maturation. Some are part of temperament, considered normal variation in personality. For example, so-called difficult temperament includes low adaptability, high-intensity reactions, low regularity, tendency to withdraw, and negative mood. But in the extreme, weaknesses in these skills are core to or comorbid with diagnosable mental health disorders. Defiance and irritable responses are criteria for oppositional defiant disorder (ODD), and less severe categories called aggressive/oppositional problem or variation. ODD is often found in children diagnosed with ADHD (65%), Tourette’s (15%-65%), depression (70% if severe), bipolar disorder (85%), OCD, anxiety (45%), autism, and language-processing disorders (55%), or trauma. These conditions variably include lower emotion regulation, poorer executive functioning including poor task shifting and impulsivity, obsessiveness, lower expressive and receptive communication skills, and less social awareness that facilitates harmonious problem solving.

The basic components of the CPS approach to addressing parent-child conflict sound intuitive but defining them clearly is important when families are stuck. There are three levels of plans. If the problem is an emergency or nonnegotiable, e.g., child hurting the cat, it may call for Plan A – parent-imposed solutions, sometimes with consequences or rewards. As children mature, Plan A should be used less frequently. If solving the problem is not a top life priority, Plan C – postponing action, may be appropriate. Plan C highlights that behavior change is a long-term project and “picking your fights” is important.

The biggest value of CPS for resolving behavior problems comes from intermediate Plan B. In Plan B the first step of problem solving for parents facing child defiance or upset is to empathically and nonjudgmentally figure out the child’s concern. Questions such as “I’ve noticed that when I remind you that it is trash night you start shouting. What’s up with that?” then patiently asking about the who, what, where, and when of their concern and checking to ensure understanding. Specificity is important as well as noting times when the reaction occurs or not.

Once the child’s concern is clear, e.g., feeling that the demand to take out the trash now interrupts his games during the only time his friends are online, the parents should echo the child’s concern then express their own concern about how the behavior is affecting them and others, potentially including the child; e.g., mother is so upset by the shouting that she can’t sleep, and worry that the child is not learning responsibility, and then checking for child understanding.

Finally, the parent invites brainstorming for a solution that addresses both of their concerns, first asking the child for suggestions, aiming for a strategy that is realistic and specific. Children reluctant to make suggestions may need more time and the parent may be wondering “if there is a way for both of our concerns to be addressed.” Solutions chosen are then tried for several weeks, success tracked, and needed changes negotiated.

For parents, using a collaborative approach to dealing with their child’s behavior takes skills they may not have at the moment, or ever. Especially under the stresses of COVID-19 lockdown, taking a step back from an encounter to consider lack of a skill to turn off the video game promptly when a Zoom meeting starts is challenging. Parents may also genetically share the child’s predisposing ADHD, anxiety, depression, OCD, or weakness in communication or social sensitivity.

Sometimes part of the solution for a conflict is for the parent to reduce expectations. This requires understanding and accepting the child’s cognitive or emotional limitations. Reducing expectations is ideally done before a request rather than by giving in after it, which reinforces protests. For authoritarian adults rigid in their belief that parents are boss, changing expectations can be tough and can feel like losing control or failing as a leader. One benefit of working with a CPS coach (see livesinthebalance.org or ThinkKids.org) is to help parents identify their own limitations.

Predicting the types of demands that tend to create conflict, such as to act immediately or be flexible about options, allows parents to prioritize those requests for calmer moments or when there is more time for discussion. Reviewing a checklist of common gaps in skills and creating a list of expectations and triggers that are difficult for the child helps the family be more proactive in developing solutions. Authors of CPS have validated a checklist of skill deficits, “Thinking Skills Inventory,” to facilitate detection of gaps that is educational plus useful for planning specific solutions.

CPS has been shown in randomized trials with both parent groups and in home counseling to be as effective as Parent Training in reducing oppositional behavior and reducing maternal stress, with effects lasting even longer.

CPS Plan B notably has no reward or punishment components as it assumes the child wants to behave acceptably but can’t; has the “will but not the skill.” When skill deficits are worked around the child is satisfied with complying and pleasing the parents. The idea of a “function” of the misbehavior for the child of gaining attention or reward or avoiding consequences is reinterpreted as serving to communicate the problem the child is having trouble in meeting the parent’s demand. When the parent understands and helps the child solve the problem his/her misbehavior is no longer needed. A benefit of the communication and mutual problem solving used in CPS is on not only improving behavior but empowering parents and children, building parental empathy, and improving child skills.

In this model, mismatch of the parent’s and child’s response patterns is seen as setting them up for chronically rough interactions around parent requests/demands. A parent escalating quickly from a briefly stated request to a tirade may create more tension paired with an anxious child who takes time to act, for example. Once a parent (and ultimately the child) recognize patterns in what leads to conflict, they can become more proactive in predicting and negotiating these situations. Ross Greene, PhD, explains this in his book “The Explosive Child,” calling the method Collaborative Problem Solving (now Collaborative & Proactive Solutions or CPS).

While there are general principles parents can use to modify what they consider “mis”behaviors, these methods often do not account for the “missing” skills of the individual child (and parent) predisposing to those “mis”takes. Thinking of misbehaviors as being because of a kind of “learning disability” in the child rather than willful defiance can help cool off interactions by instead focusing on solving the underlying problem.

What kinds of “gaps in skills” set a child up for defiant or explosive reactions? If you think about what features of children, and parent-child relationships are associated with harmonious interactions this becomes evident. Children over 3 who are patient, easygoing, flexible or adaptable, and good at transitions and problem-solving can delay gratification and tolerate frustration, regulate their emotions, explain their desires, and multitask. They are better at reading the parent’s needs and intent and tend to interpret requests as positive or at least neutral and are more likely to comply with parent requests without a fuss.

What? No kid you know is great at all of these? These skills, at best variable, develop with maturation. Some are part of temperament, considered normal variation in personality. For example, so-called difficult temperament includes low adaptability, high-intensity reactions, low regularity, tendency to withdraw, and negative mood. But in the extreme, weaknesses in these skills are core to or comorbid with diagnosable mental health disorders. Defiance and irritable responses are criteria for oppositional defiant disorder (ODD), and less severe categories called aggressive/oppositional problem or variation. ODD is often found in children diagnosed with ADHD (65%), Tourette’s (15%-65%), depression (70% if severe), bipolar disorder (85%), OCD, anxiety (45%), autism, and language-processing disorders (55%), or trauma. These conditions variably include lower emotion regulation, poorer executive functioning including poor task shifting and impulsivity, obsessiveness, lower expressive and receptive communication skills, and less social awareness that facilitates harmonious problem solving.

The basic components of the CPS approach to addressing parent-child conflict sound intuitive but defining them clearly is important when families are stuck. There are three levels of plans. If the problem is an emergency or nonnegotiable, e.g., child hurting the cat, it may call for Plan A – parent-imposed solutions, sometimes with consequences or rewards. As children mature, Plan A should be used less frequently. If solving the problem is not a top life priority, Plan C – postponing action, may be appropriate. Plan C highlights that behavior change is a long-term project and “picking your fights” is important.

The biggest value of CPS for resolving behavior problems comes from intermediate Plan B. In Plan B the first step of problem solving for parents facing child defiance or upset is to empathically and nonjudgmentally figure out the child’s concern. Questions such as “I’ve noticed that when I remind you that it is trash night you start shouting. What’s up with that?” then patiently asking about the who, what, where, and when of their concern and checking to ensure understanding. Specificity is important as well as noting times when the reaction occurs or not.

Once the child’s concern is clear, e.g., feeling that the demand to take out the trash now interrupts his games during the only time his friends are online, the parents should echo the child’s concern then express their own concern about how the behavior is affecting them and others, potentially including the child; e.g., mother is so upset by the shouting that she can’t sleep, and worry that the child is not learning responsibility, and then checking for child understanding.

Finally, the parent invites brainstorming for a solution that addresses both of their concerns, first asking the child for suggestions, aiming for a strategy that is realistic and specific. Children reluctant to make suggestions may need more time and the parent may be wondering “if there is a way for both of our concerns to be addressed.” Solutions chosen are then tried for several weeks, success tracked, and needed changes negotiated.

For parents, using a collaborative approach to dealing with their child’s behavior takes skills they may not have at the moment, or ever. Especially under the stresses of COVID-19 lockdown, taking a step back from an encounter to consider lack of a skill to turn off the video game promptly when a Zoom meeting starts is challenging. Parents may also genetically share the child’s predisposing ADHD, anxiety, depression, OCD, or weakness in communication or social sensitivity.

Sometimes part of the solution for a conflict is for the parent to reduce expectations. This requires understanding and accepting the child’s cognitive or emotional limitations. Reducing expectations is ideally done before a request rather than by giving in after it, which reinforces protests. For authoritarian adults rigid in their belief that parents are boss, changing expectations can be tough and can feel like losing control or failing as a leader. One benefit of working with a CPS coach (see livesinthebalance.org or ThinkKids.org) is to help parents identify their own limitations.

Predicting the types of demands that tend to create conflict, such as to act immediately or be flexible about options, allows parents to prioritize those requests for calmer moments or when there is more time for discussion. Reviewing a checklist of common gaps in skills and creating a list of expectations and triggers that are difficult for the child helps the family be more proactive in developing solutions. Authors of CPS have validated a checklist of skill deficits, “Thinking Skills Inventory,” to facilitate detection of gaps that is educational plus useful for planning specific solutions.

CPS has been shown in randomized trials with both parent groups and in home counseling to be as effective as Parent Training in reducing oppositional behavior and reducing maternal stress, with effects lasting even longer.

CPS Plan B notably has no reward or punishment components as it assumes the child wants to behave acceptably but can’t; has the “will but not the skill.” When skill deficits are worked around the child is satisfied with complying and pleasing the parents. The idea of a “function” of the misbehavior for the child of gaining attention or reward or avoiding consequences is reinterpreted as serving to communicate the problem the child is having trouble in meeting the parent’s demand. When the parent understands and helps the child solve the problem his/her misbehavior is no longer needed. A benefit of the communication and mutual problem solving used in CPS is on not only improving behavior but empowering parents and children, building parental empathy, and improving child skills.

In this column in September 2020, you read how common respiratory viruses’ seasons are usually so predictable, each virus arising, peaking, and then dying out in a predictable virus parade (Figure 1).¹ Well, the predictable virus seasonal pattern was lost in 2020. Since March of 2020, it is striking how little activity was detected for the usual seasonal viruses in Kansas City after mid-March 2020 (Figure 2).² So, my concern in September 2020 for possible rampant coinfections of common viruses with or in tandem with SARS-CoV-2 did not pan out. That said, the seasons for non–SARS-CoV-2 viruses did change; I just didn’t expect they would nearly disappear.

Dr. Christoper Harrison

The 2020 winter-spring. In the first quarter (the last part of the overall 2019-2020 respiratory viral season), viral detections were chugging along as usual up to mid-March (Figure 2); influenza, respiratory syncytial virus (RSV), and rhinovirus were the big players.

Influenza. In most years, influenza type B leads off and is quickly replaced by type A only to see B reemerge to end influenza season in March-April. In early 2020, both influenza type A and influenza type B cocirculated nearly equally, but both dropped like a rock in mid-March (Figure 2).² Neither type has been seen since with the exception of sporadic detections – perhaps being false positives.

RSV. In the usual year in temperate mid-latitudes of the northern hemisphere, RSV season usually starts in early December, peaks in January-March, and declines gradually until the end of RSV season in April (Figure 1). In southern latitudes, RSV is less seasonal, being present most of the year, but peaking in “winter” months.³ But in 2020, RSV also disappeared in mid-March and has yet to reappear.

Other viruses. Small bumps in detection of parainfluenza of varying types usually frame influenza season, one B bump in early autumn and another in April-May. In most years, human metapneumovirus is detected on and off, with worse years at 2- to 3-year intervals. Adenovirus occurs year-round with bumps as children get back to school in autumn. Yet in 2020, almost no parainfluenza, adenovirus, common coronaviruses, or human metapneumovirus were detected in either spring or autumn. This was supposed to be a banner summer-autumn for EV-D68 – but almost none was detected. Interestingly, the cockroach of viruses, rhinovirus, has its usual year (Figure 2).

Dr. Christopher Harrison

What happened? Intense social mitigation interventions, including social distancing and closing daycares and schools, were likely major factors.⁴ For influenza, vaccine may have helped but uptake was not remarkably better than most prior years. There may have been “viral competition,”where a new or highly transmissible virus outcompetes less-transmissible viruses with lower affinity for respiratory receptors.^5,6 Note that SARS-CoV-2 has very high affinity for the ACE2 receptor and has been highly prevalent. So, SARS-CoV-2 could fit the theoretical mold for a virus that outcompetes others.

Does it matter for the future? Blunted 2019-2020 and nearly absent 2020-2021 respiratory virus season may have set the stage for intense 2021-2022 rebounds for the non–SARS-CoV-2 viruses. We now have two whole and one partial birth cohort with no experience with seasonal respiratory viruses, including EV-D68 (and nonrespiratory viruses too – like norovirus, parechovirus, and other enteroviruses). Most viruses have particularly bad seasons every 2-3 years, thought to be caused by increasing accumulation of susceptible individuals in consecutive birth cohorts until a critical mass of susceptible individuals is achieved. The excess in susceptible individuals means that each contagious case is likely to expose one or more susceptible individuals, enhancing transmission and infection numbers in an ever-extending ripple effect. We have never had this many children aged under 3 years with no immunity to influenza, RSV, etc. So unless mother nature is kind (when has that happened lately?), expect rebound years for seasonal viruses as children return to daycare/schools and as social mitigation becomes less necessary in the waning pandemic.

Options? If you ramped up telehealth visits for the pandemic, that may be a saving grace, i.e., more efficiency so more “visits” can be completed per day, and less potential contact in reception rooms between well and ill children. And if there was ever a time to really intensify efforts to immunize all our pediatric patients, the next two seasons are just that. Adding a bit of a warning to families with young children also seems warranted. If they understand that, while 2021-2022 will be better for SARS-CoV-2, it is likely going to be worse for the other viruses.

Exposure to antibiotics in mid- to late pregnancy was associated with childhood asthma in vaginally born children, in a Danish birth cohort study.

The reason behind the correlation is unclear. Maternal infections, rather than antibiotics, “could explain the observed association,” said study author Cecilie Skaarup Uldbjerg, a researcher in the department of public health at Aarhus University in Denmark.

Still, the “results are in keeping with the hypothesis that effects of antibiotics impact the maternally derived microbiome in vaginally born children and that this may increase the odds of childhood asthma,” Ms. Uldbjerg and coauthors wrote in their study, which was published online Feb. 9 in Archives of Disease in Childhood . “However, this observational study did not address underlying mechanisms, and this interpretation, while plausible, remains speculative.”
 

Antibiotic use in pregnancy likely to continue

Patrick Duff, MD, who was not involved in the research, does not expect the findings will alter clinical practice.

The association was relatively weak, and the study does not account for factors such as antibiotic exposure during early childhood or tobacco smoke in the house, said Dr. Duff, professor of maternal-fetal medicine at University of Florida, Gainesville.

“Although I agree that we should not use antibiotics indiscriminately during pregnancy, we definitely need to treat certain infections,” Dr. Duff said. “Thus we cannot avoid some degree of antibiotic exposure.”

Although prior research has indicated that antibiotic use in pregnancy may increase the risk of asthma in children, results have been inconsistent.

To study whether antibiotic exposure during pregnancy is associated with childhood asthma and whether the timing of antibiotic exposure or mode of delivery influence the relationship, the investigators analyzed data from more than 32,000 children in the Danish National Birth Cohort, which was established in 1996.
 

Children of mothers who took and did not take antibiotics compared

In all, 17% of the children were born to mothers who used antibiotics during pregnancy. Compared with mothers who did not take antibiotics, those who did reported more maternal asthma, smoking during pregnancy, and having overweight or obesity. In addition, they were less likely to have been in their first pregnancy.

During follow-up at age 11 years, 4,238 children (13%) had asthma, including 12.7% of those whose mothers had not been exposed to antibiotics, and 14.6% of those whose mothers had used antibiotics during pregnancy.

In adjusted analyses, children born to mothers who received antibiotics were more likely to have asthma (OR, 1.14).

Antibiotic exposure in the second to third trimester, but not in the first trimester, was associated with asthma. The association was observed in vaginally born children, but not in children born by cesarean section.

The study is limited by its reliance on maternal reporting for data about antibiotics and asthma diagnoses, the authors noted. Mothers completed telephone interviews twice during pregnancy and once at 6 months postpartum. They completed online questionnaires to provide follow-up information at 11 years.
 

Mode of delivery may matter

The researchers said their analysis indicates that mode of delivery may modify the association between antibiotic exposure during pregnancy and childhood asthma.

Fourteen percent of the children in the study were delivered by cesarean section. Further research may clarify the relationship between antibiotics in pregnancy, mode of delivery, and asthma risk, another doctor who was not involved the study added.

“I do not think that the evidence indicates that mode of delivery clearly has an impact,” said Santina J. G. Wheat, MD, MPH, associate professor of family and community medicine at Northwestern University in Chicago, “as the number of cesarean deliveries was not large enough to fully support such a statement.

“It will be interesting to see if an association holds in future studies with increased cesarean deliveries,” Dr. Wheat said.

How and why antibiotics were used may be other important factors to investigate, Dr. Duff suggested.

“The authors did not provide any specific information about which antibiotics were used by the mothers, duration of use, and indication for use. Those are very important confounders,” Dr. Duff said. “Perhaps the key exposure is to a particular maternal infection rather than to the antibiotic per se.”

The Danish National Birth Cohort was established with a grant from the Danish National Research Foundation and support from regional committees and other organizations. Its biobank has been supported by the Novo Nordisk Foundation and the Lundbeck Foundation, and follow-up of mothers and children has been supported by the Danish Medical Research Council, the Lundbeck Foundation, Innovation Fund Denmark, the Nordea Foundation, Aarhus Ideas, a University of Copenhagen strategic grant, and the Danish Council for Independent Research. The study was partially funded by the Health Research Fund of Central Denmark Region, which supported one of the authors. Other authors were supported by the DHB Foundation and the Australian National Health and Medical Research Council. One author is affiliated with Murdoch Children’s Research Institute in Australia, where the Victorian Government’s Operational Infrastructure Support Program supports research.

Exposure to antibiotics in mid- to late pregnancy was associated with childhood asthma in vaginally born children, in a Danish birth cohort study.

The reason behind the correlation is unclear. Maternal infections, rather than antibiotics, “could explain the observed association,” said study author Cecilie Skaarup Uldbjerg, a researcher in the department of public health at Aarhus University in Denmark.

Still, the “results are in keeping with the hypothesis that effects of antibiotics impact the maternally derived microbiome in vaginally born children and that this may increase the odds of childhood asthma,” Ms. Uldbjerg and coauthors wrote in their study, which was published online Feb. 9 in Archives of Disease in Childhood . “However, this observational study did not address underlying mechanisms, and this interpretation, while plausible, remains speculative.”
 

Antibiotic use in pregnancy likely to continue

Patrick Duff, MD, who was not involved in the research, does not expect the findings will alter clinical practice.

The association was relatively weak, and the study does not account for factors such as antibiotic exposure during early childhood or tobacco smoke in the house, said Dr. Duff, professor of maternal-fetal medicine at University of Florida, Gainesville.

“Although I agree that we should not use antibiotics indiscriminately during pregnancy, we definitely need to treat certain infections,” Dr. Duff said. “Thus we cannot avoid some degree of antibiotic exposure.”

Although prior research has indicated that antibiotic use in pregnancy may increase the risk of asthma in children, results have been inconsistent.

To study whether antibiotic exposure during pregnancy is associated with childhood asthma and whether the timing of antibiotic exposure or mode of delivery influence the relationship, the investigators analyzed data from more than 32,000 children in the Danish National Birth Cohort, which was established in 1996.
 

Children of mothers who took and did not take antibiotics compared

In all, 17% of the children were born to mothers who used antibiotics during pregnancy. Compared with mothers who did not take antibiotics, those who did reported more maternal asthma, smoking during pregnancy, and having overweight or obesity. In addition, they were less likely to have been in their first pregnancy.

During follow-up at age 11 years, 4,238 children (13%) had asthma, including 12.7% of those whose mothers had not been exposed to antibiotics, and 14.6% of those whose mothers had used antibiotics during pregnancy.

In adjusted analyses, children born to mothers who received antibiotics were more likely to have asthma (OR, 1.14).

Antibiotic exposure in the second to third trimester, but not in the first trimester, was associated with asthma. The association was observed in vaginally born children, but not in children born by cesarean section.

The study is limited by its reliance on maternal reporting for data about antibiotics and asthma diagnoses, the authors noted. Mothers completed telephone interviews twice during pregnancy and once at 6 months postpartum. They completed online questionnaires to provide follow-up information at 11 years.
 

Mode of delivery may matter

The researchers said their analysis indicates that mode of delivery may modify the association between antibiotic exposure during pregnancy and childhood asthma.

Fourteen percent of the children in the study were delivered by cesarean section. Further research may clarify the relationship between antibiotics in pregnancy, mode of delivery, and asthma risk, another doctor who was not involved the study added.

“I do not think that the evidence indicates that mode of delivery clearly has an impact,” said Santina J. G. Wheat, MD, MPH, associate professor of family and community medicine at Northwestern University in Chicago, “as the number of cesarean deliveries was not large enough to fully support such a statement.

“It will be interesting to see if an association holds in future studies with increased cesarean deliveries,” Dr. Wheat said.

How and why antibiotics were used may be other important factors to investigate, Dr. Duff suggested.

“The authors did not provide any specific information about which antibiotics were used by the mothers, duration of use, and indication for use. Those are very important confounders,” Dr. Duff said. “Perhaps the key exposure is to a particular maternal infection rather than to the antibiotic per se.”

The Danish National Birth Cohort was established with a grant from the Danish National Research Foundation and support from regional committees and other organizations. Its biobank has been supported by the Novo Nordisk Foundation and the Lundbeck Foundation, and follow-up of mothers and children has been supported by the Danish Medical Research Council, the Lundbeck Foundation, Innovation Fund Denmark, the Nordea Foundation, Aarhus Ideas, a University of Copenhagen strategic grant, and the Danish Council for Independent Research. The study was partially funded by the Health Research Fund of Central Denmark Region, which supported one of the authors.

Case

Max was a 17-year-old boy and avid video gamer who, predating COVID-19, was within a major depressive episode and continued to meet criteria through the duration of COVID-19 quarantine. He lives with his mother, who is a single mom and is working hard in a variety of jobs through the pandemic. Max had little motivation to engage in sports or other activities, and despite doing well enough in school, he spent much of his days escaping into video games and social media, where his friends communicated and bonded the most. He has had very little response to complete trials of two different selective serotonin reuptake inhibitors (SSRIs), and the off-label attempts at a serotonin-norepinephrine reuptake inhibitor and bupropion augmentation of an SSRI, as extrapolated by his pediatrician from adult data on treatment-resistant depression. He had ongoing supportive psychotherapy and his mother and pediatrician were wary of changing that relationship, as they were just happy he would engage at all. His shy nature made him very wary of attending any programs or groups. He had no other diagnosis including anxiety, substance abuse disorder, or learning disorder.

Case discussion

As a child and adolescent psychiatrist embedded in primary care practices, I (like you) am seeing more and more parents, children, and families struggling with depression through the course of this unprecedented and challenging year.

Max presented to me with his mother at the request of his primary care physician because within the course of many medication trials, it had been over 6 months of persistent symptoms without an end in sight for him, his family, or his primary care provider (PCP).

His diagnosis was treatment-resistant depression and his PCP was grasping at adult strategies to manage this all with additional psychopharmacology. As a consulting child-and-adolescent psychiatrist in primary care, how could I help the PCP? I too worry if there is anything that I can do to shift depression once standard treatments fail, and when the idea of engaging in behavioral activation or other pro-health activities is just too much for a depressed adolescent to bear. I weigh that with what is known about the evidence, and the good data driving us beyond medication solutions. I often find that it can be helpful to reiterate the following points to providers and families.
 

First, what to know about depression in kids

Depression looks different at different ages in children. In school-aged children, it’s widely known that irritability or psychosomatic symptoms (frequent headaches and stomach aches) can be the first preverbal signs of an emerging anxiety and depressive disorder in children. In adolescents, one would maybe expect more typical melancholic adult-like symptoms of depression; however, there is mounting evidence that adolescents actually present with more classically “atypical symptoms” of depression (low motivation, weight gain, escapism to sleep or video games, as with Max) with less persistence across setting (home, work, school) compared with adults (“Diagnosing Depression in Children and Adolescents” by Glen R. Elliott, PhD, MD, from The Carlat Child Psychiatry Report, November 2015, Antidepressant Use in Children).In addition, major life stressors (the breakup of a romantic relationship, failing a class, bullying) can be perceived as more permanent, and suicidal thinking can be acute and lethal in these contexts. With Max, it was accepted by all who were supporting him that he was struggling with depression, which is the first step in managing this well.

The idea of the designated patient

Often left out in a discussion of pediatric patients is the family. As a designated patient, much of our focus is on improving the symptoms of the patient in front of us. Parents direct their gaze at the child as the one with the condition who needs support. First following identification of depression, I find that a reframe of a diagnosis can be useful. Family systems theory approaches a child with a depression diagnosis, and says, that if one family member changes, even in a small way, a family as a system is forced to change. With a sense of an external locus of control, we often are left with a patient and parent feeling stuck. To provide a reorientation to the parents, ask how they are feeling. Can they get treatment for depression knowing the biology of the condition or consider making behavioral changes of their own and as a family? Can they consider family psychotherapy so they can cope better and break some cycles of maladaptive engagement shared across a family? These kinds of reorientations can be useful to shift the idea of treatment from the designated patient (the child) and medication options (limited data for kids who aren’t responding to them) to a family approach. Making the depression management strategy a family affair can help the entire family shift from seeing the only option as medications or interventions exclusively directed at a child. The Vermont Center for Children, Youth, and Families at the University of Vermont Medical Center has many pioneering developments in addressing family-based approaches to mental health concerns in the pediatric population, and can serve as a source of inspiration for this shift in discussing depression.

Practical strategies for the pediatrician

Medications can be useful for treating child and adolescent depression, but there is also strong evidence for psychotherapy, working with the child’s school and family, and different forms of behavioral activation (exercise, mindfulness, yoga, and other positive activities). Medications, if one is looking at standard of care treatment and Food and Drug Administration approval exclusively, is limited in scope and should not be the only intervention considered, as described in the case above.

In “The Use of Medication in Treating Childhood and Adolescent Depression: Information for Patients and Families,” which is a practical guide prepared by the American Psychiatric Association and the American Academy of Child and Adolescent Psychiatry, it is noted that Prozac and Lexapro are approved medications, as follows:

• Antidepressant medications can be effective in relieving the symptoms of depression for some children and adolescents. One antidepressant – fluoxetine, or Prozac – a medicine in the category of SSRIs, has been approved by the FDA for treating depression in children 8 years of age and older. Escitalopram, or Lexapro, has also been approved by the FDA for treating adolescents 12 years of age and older.
• About “60 percent of children and adolescents will respond to initial treatment with medication,” which leaves many children needing further interventions. “Of those who don’t [respond], a significant number may respond to another medication but also may respond to the addition of a form of psychotherapy called cognitive behavioral therapy (CBT).”

It is common, as in the case above, that a connection with a therapist or support is valued over the specific modality even if it’s not showing improvement or outcomes. It is important to consider CBT as a form of evidence-based treatment for children with depression and to cite the famous “Treatment for Adolescents with Depression Study (TADS)” funded by the National Institute of Mental Health, published in 2004, that shows the following findings: “After 12 weeks of treatment, 71 percent of the patients who received the combination of medication and CBT were much improved.” In looking at the group that does not improve with medications alone, adolescents in particular can have more gains with the addition of CBT.
 

Tracking progress, little by little

Often we reflexively ask parents of depressed children: Are they better? And we ask the child: How do you feel? It can be difficult for parents to reflect on that, or see progress or gains from appointment to appointment. I suggest trying to use structured measures and tools to frame a discussion with progress on medication and treatment such as what is available at the Mood Treatment Center website.I also suggest apps such as Mood Kit,which is for mood tracking with some CBT exercises in addition to behavioral activation strategies for children and parents. It can be useful to have families take some ownership of tracking their moods and what may be playing into them. In particular with the pandemic, we can reflect on how much isolation or socialization, activities, sleep, eating habits, and exercise can affect us and make corresponding behavioral changes as a family to improve our own coping. Depression itself can be like glasses clouding one’s vision in gray, and that can also cloud one’s review of progress. When we hear comments such as “nothing gets better” from a child or parent, it may be helpful to try to track any contributing factors to a persistent low mood and acknowledge any slow and steady progress.

In summary, we can strive as providers to maximize our approach to depression in children and adolescents beyond the limited FDA-approved medications, or extrapolating adult data to children. If we emphasize the evidence-based practice of CBT and other interventions in addition to encouraging a tracking and review of outcomes measures with parents and families, we can empower them to make meaningful change in both perspectives and behaviors that can perpetuate depressive states.
