LAS VEGAS – The Melody transcatheter pulmonary valve showed durable efficacy out to 5 years after placement in a mandated U.S. postapproval study that followed 65 patients, a majority of whom were children or teenagers.

After 5 years, 69% of the replacement valve recipients had no valvular hemodynamic dysfunction, compared with a 67% rate among patients enrolled in the original Investigational Device Exemption (IDE) study that led to Food and Drug Administration marketing approval for the Melody valve in 2010 under a humanitarian device exemption. (Full approval followed in 2017.)

The 5-year rate of any reintervention, including explants, was 78% in the postapproval study, again similar to the 76% rate reported in the IDE study after a median 4.5 year follow-up (Circulation. 2015 Jun 2;131[22]:1960-70), Aimee K. Armstrong, MD, said at the Society for Cardiovascular Angiography & Interventions annual scientific sessions.

The new 5-year postapproval study findings “confirm that the hemodynamic effectiveness achieved by real-world providers is equivalent to the historical control established in the IDE study,” concluded Dr. Armstrong, professor of pediatrics at the Ohio State University and director of cardiac catheterization and interventional therapies at Nationwide Children’s Hospital, both in Columbus.

The postapproval study ran at 10 U.S. centers, none of which were among the five U.S. centers that ran the IDE study. Today, the Melody transcatheter pulmonary valve “is very commonly used” at many additional U.S. sites, Dr. Armstrong said in an interview. And the outcomes achieved using the valve likely surpass those seen in the IDE and postapproval studies because of innovations in technique, such as more routine use of “prestenting,” placing a stent in the vascular site where the pulmonary valve conduit will sit to address stenosis at this location and prevent subsequent conduit fracture (JACC Cardiovasc Interv. 2017 Sep;10[17]:1760-2).

“In 2010 [when the postapproval study began], we didn’t understand the importance of prestenting the way we do now. In 2010, I did not prestent every patient; now I do,” she said. The results reported by Dr. Armstrong included a 5% cumulative rate of major stent fractures in the Melody devices.

The postapproval study results also documented a concerning 4.5% annualized incidence of endocarditis among pulmonary valve recipients, with a nearly 300% increased rate of endocarditis among patients aged 12 years or younger, compared with older patients. Dr. Armstrong cautioned that this age association may be confounded by other factors, such as a residual pressure gradient in the right ventricular outflow tract of 15 mm Hg or greater. “We are discovering that we need to reduce the pressure gradient as much as we can, to perhaps less than 15 mm Hg, to reduce endocarditis, and that is something we did not know even a year ago. Practice is still evolving.”

The Melody Transcatheter Pulmonary Valve Postapproval Study performed cardiac catheterization for valve placement in 121 patients, and successfully implanted the valve for at least 24 hours in 99 of these patients. Patient age ranged from 5 to 45 years, with a median of 17 years; two-thirds were boys or men. The median age of the patients in the postapproval study was about 2 years younger than in the IDE study. Dr. Armstrong and her associates had previously published the 1-year outcomes from the postapproval study (JACC Cardiovasc Interv. 2014 Nov;7[11]:1254-62).

The enrolled patients usually needed a new right ventricular outflow tract because of a congenital heart defect, such as tetralogy of Fallot with pulmonary atresia and truncus arteriosus. Patients also included those who underwent a Ross operation. These patients often receive surgical placement of a right ventricular-to-pulmonary artery conduit, which can over time develop stenosis, insufficiency, or both because of calcification, intimal proliferation, and graft degeneration.

Multiple conduit reoperations to restore right ventricular outflow tract function are usually needed over a patient’s lifetime because of conduit degeneration. This makes a transcatheter procedure in a child or adolescent an attractive option because the prosthetic conduit will need replacement relatively quickly, and the transcatheter approach avoids an episode of open-heart surgery.

The Melody system is not the only transcatheter option for treating a leak or stenosis in a right ventricular outflow tract. The Sapien XT Transcatheter Heart Valve, marketed by Edwards, has FDA labeling for replacement of a dysfunctional right ventricular outflow tract.

Because the Sapien XT system was designed for replacing an aortic valve it’s challenging to place the conduit in the pulmonary valve position, Dr. Armstrong said. Operators find the Sapien 3 valve, a more modern design of the XT model that’s also primarily intended for aortic valve replacement, easier to position than the XT for pulmonary valve replacement, but Sapien 3 does not have FDA labeling for the right ventricular outflow tract indication. The Sapien valves are attractive because they don’t fracture, but Melody is easier to place and operators can reduce the fracture risk by prestenting, she noted.

Overall, the 5-year results from the postapproval study represented success, because 78% of patients who received the Melody device avoided any further interventions during follow-up. “That’s a big deal to a 12, 15, or 18 year old,” said Dr. Armstrong. “A surgically placed valve won’t last long in a teen, so it’s nice to do something noninvasively. It’s great if you can delay surgery for a few years” and avoid having the patient grow out of a surgically placed conduit or developing lots of calcification in the conduit during a growth spurt.

The postapproval study was funded by Medtronic, the company that sells the Melody valve. Dr. Armstrong has received research funding from Medtronic as well as Abbott, Edwards, and Siemens, and she has been a consultant to Abbott.

CHICAGO – Administering CPX-351 prior to a three-drug regimen produced a high response rate in pediatric patients with acute myeloid leukemia (AML) in first relapse.

Jennifer Smith/MDedge News

In a phase 1/2 trial, CPX-351 followed by fludarabine, cytarabine, and filgrastim (FLAG) produced an overall response rate of 81%, and 70% of responders had their best response while receiving CPX-351.

“This is the best response rate published in North America for those [pediatric AML patients] in first relapse,” said Todd Cooper, DO, of Seattle Children’s Hospital in Washington.

Dr. Cooper presented results from the phase 1/2 AAML1421 trial (NCT02642965) at the annual meeting of the American Society of Clinical Oncology.

The primary objective of phase 1 was to determine the recommended phase 2 dose and toxicities of CPX-351, a liposomal preparation of cytarabine and daunorubicin. The primary objective of phase 2 was to assess the best response in patients who received CPX-351 in cycle 1 and FLAG in cycle 2.

The trial enrolled 38 AML patients, 6 in the dose-finding phase and 32 in the efficacy phase. The patients’ median age at study entry was 11.91 years (range, 1.81-21.5). Most patients (88.9%) had CNS 1 disease, and most (73.7%) had not received a transplant.

Half of patients had a first complete response (CR) that lasted 180 to 365 days, 13.2% had a first CR lasting less than 180 days, and 36.8% had a first CR lasting more than 1 year.

Dosing and toxicity

During the dose-finding portion of the study, the first dose level of CPX-351 was 135 units/m² on days 1, 3, and 5. There was one dose-limiting toxicity — grade 3 decrease in ejection fraction — so 135 units/m² was deemed the recommended phase 2 dose.

The most common grade 3 or higher adverse events observed with CPX-351 in cycle 1 were infections and infestations (47.4%), febrile neutropenia (44.7%), maculopapular rash (39.5%), and prolonged QT interval (18.4%).

The most common grade 3 or higher adverse events observed with FLAG in cycle 2 were febrile neutropenia (23.1%), prolonged QT interval (23.1%), and infections and infestations (19.2%).

Response and survival

There were 37 patients evaluable for response. The overall response rate was defined as CR plus CR without platelet recovery (CRp) plus CR with incomplete hematologic recovery (CRi).

The overall response rate was 81.1% (n = 30), which included 20 CRs (54.1%), 5 CRps (13.5%), and 5 CRis (13.5%). Five patients had a partial response (13.5%), and two patients had treatment failure (5.4%).

During CPX-351 treatment (n = 37), the CR rate was 37.8% (n = 14), the CRp rate was 5.4% (n = 2), and the CRi rate was 32.4% (n = 12).

During FLAG treatment (n = 27), the CR rate was 48.1% (n = 13), the CRp rate was 25.9% (n = 7), and the CRi rate was 7.4% (n = 2).

Of the 25 patients who achieved a CR or CRp at any time, 21 (84%) were minimal residual disease negative by flow cytometry. Twelve patients were minimal residual disease negative after cycle 1.

Most patients who achieved a CRi or better (83.3%) went on to hematopoietic stem cell transplant.

The 2-year overall survival was 47% for all patients and 60% for responders. None of the non-responders were still alive 2 years after therapy.

“The results certainly warrant a phase 3 study of CPX-351,” Dr. Cooper said. “In fact, it is the lead molecule that’s going to be incorporated into the next COG phase 3 study.”

AAML1421 was sponsored by the Children’s Oncology Group in collaboration with the National Cancer Institute. Dr. Cooper disclosed relationships with Juno Therapeutics and Celgene.

Of the 25 patients who achieved a CR or CRp at any time, 21 (84%) were minimal residual disease negative by flow cytometry. Twelve patients were minimal residual disease negative after cycle 1.

Most patients who achieved a CRi or better (83.3%) went on to hematopoietic stem cell transplant.

The 2-year overall survival was 47% for all patients and 60% for responders. None of the non-responders were still alive 2 years after therapy.

Managing agitation—verbal and/or motor restlessness that often is accompanied by irritability and a predisposition to aggression or violence—can be challenging in any patient, but particularly so in children and adolescents. In the United States, the prevalence of children and adolescents presenting to an emergency department (ED) for treatment of psychiatric symptoms, including agitation, has been on the rise.^1,2

Similar to the multitude of causes of fever, agitation among children and adolescents has many possible causes.³ Because agitation can pose a risk for harm to others and/or self, it is important to manage it proactively. Other than studies that focus on agitation in pediatric anesthesia, there is a dearth of studies examining agitation and its treatment in children and adolescents. There is also a scarcity of training in the management of acute agitation in children and adolescents. In a 2017 survey of pediatric hospitalists and consultation-liaison psychiatrists at 38 academic children’s hospitals in North America, approximately 60% of respondents indicated that they had received no training in the evaluation or management of pediatric acute agitation.⁴ In addition, approximately 54% of participants said they did not screen for risk factors for pediatric agitation, even though 84% encountered the condition at least once a month, and as often as weekly.⁴

This article reviews evidence on the causes and treatments of agitation in children and adolescents. For the purposes of this review, child refers to a patient age 6 to 12, and adolescent refers to a patient age 13 to 17.

Identifying the cause

Addressing the underlying cause of agitation is essential. It’s also important to manage acute agitation while the underlying cause is being investigated in a way that does not jeopardize the patient’s emotional or physical safety.

Agitation in children or teens can be due to psychiatric causes such as autism, attention-deficit/hyperactivity disorder (ADHD), or posttraumatic stress disorder (PTSD), or due to medical conditions such as delirium, traumatic brain injury, or other conditions (Table 1).

In a 2005 study of 194 children with agitation in a pediatric post-anesthesia care unit, pain (27%) and anxiety (25%) were found to be the most common causes of agitation.³ Anesthesia-related agitation was a less common cause (11%). Physiologic anomalies were found to be the underlying cause of agitation in only 3 children in this study, but were undiagnosed for a prolonged period in 2 of these 3 children, which highlights the importance of a thorough differential diagnosis in the management of agitation in children.³

Assessment of an agitated child should include a comprehensive history, physical exam, and laboratory testing as indicated. When a pediatric patient comes to the ED with a chief presentation of agitation, a thorough medical and psychiatric assessment should be performed. For patients with a history of psychiatric diagnoses, do not assume that the cause of agitation is psychiatric.

Continue to: Psychiatric causes

Autism spectrum disorder. Children and teens with autism often feel overwhelmed due to transitions, changes, and/or sensory overload. This sensory overload may be in response to relatively subtle sensory stimuli, so it may not always be apparent to parents or others around them.

Research suggests that in general, the ability to cope effectively with emotions is difficult without optimal language development. Due to cognitive/language delays and a related lack of emotional attunement and limited skills in recognizing, expressing, or coping with emotions, difficult emotions in children and adolescents with autism can manifest as agitation.

Attention-deficit/hyperactivity disorder. Children with ADHD may be at a higher risk for agitation, in part due to poor impulse control and limited coping skills. In addition, chronic negative feedback (from parents, teachers, or both) may contribute to low self-esteem, mood symptoms, defiance, and/or other behavioral difficulties. In addition to standard pharmacotherapy for ADHD, treatment involves parent behavior modification training. Setting firm yet empathic limits, “picking battles,” and implementing a developmentally appropriate behavioral plan to manage disruptive behavior in children or adolescents with ADHD can go a long way in helping to prevent the emergence of agitation.

Posttraumatic stress disorder. In some young children, new-onset, unexplained agitation may be the only sign of abuse or trauma. Children who have undergone trauma tend to experience confusion and distress. This may manifest as agitation or aggression, or other symptoms such as increased anxiety or nightmares.⁵ Trauma may be in the form of witnessing violence (domestic or other); experiencing physical, sexual, and/or emotional abuse; or witnessing/experiencing other significant threats to the safety of self and/or loved ones. Re-establishing (or establishing) a sense of psychological and physical safety is paramount in such patients.⁶ Psychotherapy is the first-line modality of treatment in children and adolescents with PTSD.⁶ In general, there is a scarcity of research on medication treatments for PTSD symptoms among children and adolescents.⁶

Oppositional defiant disorder/conduct disorder. Oppositional defiant disorder (ODD) can be comorbid with ADHD. The diagnosis of ODD requires a pervasive pattern of anger, defiance, vindictiveness, and hostility, particularly towards authority figures. However, these symptoms need to be differentiated from the normal range of childhood behavior. Occasionally, children learn to cope maladaptively through disruptive behavior or agitation. Although a parent or caregiver may see this behavior as intentionally malevolent, in a child with limited coping skills (whether due to young age, developmental/cognitive/language/learning delays, or social communication deficits) or one who has witnessed frequent agitation or aggression in the family environment, agitation and disruptive behavior may be a maladaptive form of coping. Thus, diligence needs to be exercised in the diagnosis of ODD and in understanding the psychosocial factors affecting the child, particularly because impulsiveness and uncooperativeness on their own have been found to be linked to greater likelihood of prescription of psychotropic medications from multiple classes.⁷ Family-based interventions, particularly parent training, family therapy, and age-appropriate child skills training, are of prime importance in managing this condition.⁸ Research shows that a shortage of resources, system issues, and cultural roadblocks in implementing family-based psychosocial interventions also can contribute to the increased use of psychotropic medications for aggression in children and teens with ODD, conduct disorder, or ADHD.⁸ The astute clinician needs to be cognizant of this before prescribing.

Continue to: Hallucinations/psychosis

Hallucinations/psychosis. Hallucinations (whether from psychiatric or medical causes) are significantly associated with agitation.⁹ In particular, auditory command hallucinations have been linked to agitation. Command hallucinations in children and adolescents may be secondary to early-onset schizophrenia; however, this diagnosis is rare.¹⁰ Hallucinations can also be an adverse effect of amphetamine-based stimulant medications in children and adolescents. Visual hallucinations are most often a sign of an underlying medical disorder such as delirium, occipital lobe mass/infection, or drug intoxication or withdrawal. Hallucinations need to be distinguished from the normal, imaginative play of a young child.¹⁰

Bipolar mania. In adults, bipolar disorder is a primary psychiatric cause of agitation. In children and adolescents, the diagnosis of bipolar disorder can be complex and requires careful and nuanced history-taking. The risks of agitation are greater with bipolar disorder than with unipolar depression.^11,12

Disruptive mood dysregulation disorder. Prior to DSM-5, many children and adolescents with chronic, non-episodic irritability and severe outbursts out of proportion to the situation or stimuli were given a diagnosis of bipolar disorder. These symptoms, in combination with other symptoms, are now considered part of disruptive mood dysregulation disorder when severe outbursts in a child or adolescent occur 3 to 4 times a week consistently, for at least 1 year. The diagnosis of disruptive mood dysregulation disorder requires ruling out other psychiatric and medical conditions, particularly ADHD.¹³

Substance intoxication/withdrawal. Intoxication or withdrawal from substances such as alcohol, stimulant medications, opioids, methamphetamines, and other agents can lead to agitation. This is more likely to occur among adolescents than children.¹⁴

Adjustment disorder. Parental divorce, especially if it is conflictual, or other life stressors, such as experiencing a move or frequent moves, may contribute to the development of agitation in children and adolescents.

Continue to: Depression

Depression. In children and adolescents, depression can manifest as anger or irritability, and occasionally as agitation.

Medical causes

Delirium. Refractory agitation is often a manifestation of delirium in children and adolescents.¹⁵ If unrecognized and untreated, delirium can be fatal.¹⁶ Therefore, it is imperative that clinicians routinely assess for delirium in any patient who presents with agitation.

Because a patient with delirium often presents with agitation and visual or auditory hallucinations, the medical team may tend to assume these symptoms are secondary to a psychiatric disorder. In this case, the role of the consultation-liaison psychiatrist is critical for guiding the medical team, particularly to continue a thorough exploration of underlying causes while avoiding polypharmacy. Noise, bright lights, frequent changes in nursing staff or caregivers, anticholinergic or benzodiazepine medications, and frequent changes in schedules should be avoided to prevent delirium from occurring or getting worse.¹⁷ A multidisciplinary team approach is key in identifying the underlying cause and managing delirium in pediatric patients.

Traumatic brain injury. Agitation may be a presenting symptom in youth with traumatic brain injury (TBI).¹⁸ Agitation may present often in the acute recovery phase.¹⁹ There is limited evidence on the efficacy and safety of pharmacotherapy for agitation in pediatric patients with TBI.¹⁸

Autoimmune conditions. In a study of 27 patients with anti-N-methyl-d-aspartate receptor encephalitis, Mohammad et al²⁰ found that agitation was a common symptom.

Continue to: Medication-induced/iatrogenic

Medication-induced/iatrogenic. Agitation can be an adverse effect of medications such as amantadine (often used for TBI),¹⁸ atypical antipsychotics,²¹ selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors.

Infection. Agitation can be a result of encephalitis, meningitis, or other infectious processes.²²

Metabolic conditions. Hepatic or renal failure, diabetic ketoacidosis, and thyroid toxicosis may cause agitation in children or adolescents.²²

Start with nonpharmacologic interventions

Few studies have examined de-escalation techniques in agitated children and adolescents. However, verbal de-escalation is generally viewed as the first-line technique for managing agitation in children and adolescents. When feasible, teaching and modeling developmentally appropriate stress management skills for children and teens can be a beneficial preventative strategy to reduce the incidence and worsening of agitation.²³

Clinicians should refrain from using coercion.²⁴ Coercion could harm the therapeutic alliance, thereby impeding assessment of the underlying causes of agitation, and can be particularly harmful for patients who have a history of trauma or abuse. Even in pediatric patients with no such history, coercion is discouraged due to its punitive connotations and potential to adversely impact a vulnerable child or teen.

Continue to: Establishing a therapeutic rapport...

Establishing a therapeutic rapport with the patient, when feasible, can facilitate smoother de-escalation by offering the patient an outlet to air his/her frustrations and emotions, and by helping the patient feel understood.²⁴ To facilitate this, ensure that the patient’s basic comforts and needs are met, such as access to a warm bed, food, and safety.²⁵

The psychiatrist’s role is to help uncover and address the underlying reason for the patient’s agony or distress. Once the child or adolescent has calmed, explore potential triggers or causes of the agitation.

There has been a significant move away from the use of restraints for managing agitation in children and adolescents.²⁶ Restraints have a psychologically traumatizing effect,²⁷ and have been linked to life-threatening injuries and death in children.²⁴

Pharmacotherapy: Proceed with caution

There are no FDA-approved medications for the treatment of agitation in the general pediatric population, and any medication use in this population is off-label. There is also a dearth of research examining the safety and efficacy of using psychotropic medications for agitation in pediatric patients. Because children and adolescents are more susceptible to adverse effects and risks associated with the use of psychotropic medications, special caution is warranted. In general, pharmacologic interventions are not recommended without the use of psychotherapy-based modalities.

In the past, the aim of using medications to treat patients with agitation was to put the patient to sleep.²⁵ This practice did not help clinicians to assess for underlying causes, and was often accompanied by a greater risk of adverse effects and reactions.²⁴ Therefore, the goal of medication treatment for agitation is to help calm the patient instead of inducing sleep.²⁵

Continue to: Pharmacotherapy should...

Pharmacotherapy should be used only when behavioral interventions have been unsuccessful. Key considerations for using psychotropic medications to address agitation in children and adolescents are summarized in Table 2.²⁵

Antipsychotics, particularly second-generation antipsychotics (SGAs), have been commonly used to manage acute agitation in children and adolescents, and there has been an upswing in the use of these medications in the United States in the last several years.²⁸ Research indicates that males, children and adolescents in foster care, and those with Medicaid have been the more frequent youth recipients of SGAs.²⁹ Of particular concern is the prevalence of antipsychotic use among children younger than age 6. In the last few decades, there has been an increase in the prescription of antipsychotics for children younger than age 6, particularly for disruptive behavior and aggression.³⁰ In a study of preschool-age Medicaid patients in Kentucky, 70,777 prescriptions for SGAs were given to 6,915 children <6 years of age; 73% of these prescriptions were for male patients.³⁰ Because there is a lack of controlled studies examining the safety and efficacy of SGAs among children and adolescents, especially with long-term use, further research is needed and caution is warranted.²⁸

The FDA has approved risperidone (for patients age 5 to 16) and oral aripiprazole (for patients age 6 to 17) for treating irritability related to autism spectrum disorder; irritability can contribute to or exacerbate agitation. The FDA has also approved several antipsychotic medications for treating schizophrenia or bipolar disorder in adolescents of varying ages. However, SGAs have also been found to be used commonly among young patients who do not meet criteria for autism, schizophrenia, or bipolar disorder. Aggression is the most common symptom for which SGAs are used among the pediatric population.²⁹ Careful and judicious weighing of the risks and benefits is warranted before using antipsychotic medications in a child or adolescent.

Externalizing disorders among children and adolescents tend to get treated with antipsychotics.²⁸ A Canadian study examining records of 6,916 children found that most children who had been prescribed risperidone received it for ADHD or conduct disorder, and most patients had not received laboratory testing for monitoring the antipsychotic medication they were taking.³¹ In a 2018 study examining medical records of 120 pediatric patients who presented to an ED in British Columbia with agitation, antipsychotics were the most commonly used medications for patients with autism spectrum disorder; most patients received at least 1 dose.¹⁴

For children and adolescents with agitation or aggression who were admitted to inpatient units, IM olanzapine and ziprasidone were found to exhibit similar efficacy when used to treat agitation.^14,21,32

Continue to: In case reports...

In case reports, a combination of olanzapine with CNS-suppressing agents has resulted in death. Therefore, do not combine olanzapine with agents such as benzodiazepines.²⁵ In a patient with a likely medical source of agitation, insufficient evidence exists to support the use of olanzapine, and additional research is needed.²⁵

Low-dose haloperidol has been found to be effective for delirium-related agitation in pediatric studies.¹⁵ Before initiating an antipsychotic for any child or adolescent, review the patient’s family history for reports of early cardiac death and the patient’s own history of cardiac symptoms, palpitations, syncope, or prolonged QT interval. Monitor for QT prolongation. Among commonly used antipsychotics, the risk of QT prolongation is higher with IV administration of haloperidol and with ziprasidone. Studies show that compared with oral or IM haloperidol, the IV formulation has a higher risk of increased QTc interval, torsades de pointes, and sudden death.³³ The FDA recommends continuous cardiac monitoring in adults receiving IV haloperidol. Data for its safety in children and adolescents are insufficient.

A few studies have found risperidone to be efficacious for treating ODD and conduct disorder; however, this use is off-label, and its considerable adverse effect and risk profile needs to be weighed against the potential benefit.⁸

Antipsychotic polypharmacy should be avoided because of the higher risk of adverse effects and interactions, and a lack of robust, controlled studies evaluating the safety of using antipsychotics for non-FDA-approved indications in children and adolescents.⁷ All patients who receive antipsychotics require monitoring for extrapyramidal symptoms, tardive dyskinesia, neuroleptic malignant syndrome, orthostatic hypotension, sedation, metabolic syndrome, and other potential adverse effects. Patients receiving risperidone need to have their prolactin levels monitored periodically, and their parents should be made aware of the potential for hyperprolactinemia and other adverse effects. Aripiprazole and quetiapine may increase the risk of suicidality.

Antiepileptics. A meta-analysis of 7 randomized controlled trials examining the use of antiepileptic medications (valproate, lamotrigine, levetiracetam, and topiramate) in children with autism spectrum disorder found no significant difference between placebo and these medications for addressing agitation.³⁴

Continue to: In a retrospective case series...

In a retrospective case series of 30 pedi­atric patients with autism spectrum disorder who were given oxcarbazepine, Douglas et al³⁵ found that 47% of participants experienced significant improvement in irritability/agitation. However, 23% of patients reported significant adverse effects leading to discontinuation. Insufficient evidence exists for the safety and efficacy of oxcarbazepine in this population.³⁵

Benzodiazepines. The use of benzodiazepines in pediatric patients has been associated with paradoxical disinhibition reactions, particularly in children with autism and other developmental or cognitive disabilities or delays.²¹ There is a lack of data on the safety and efficacy of long-term use of benzodiazepines in children, especially in light of these patients’ developing brains, the risk of cognitive impairment, and the potential for dependence with long-term use. Despite this, some studies show that the use of benzodiazepines is fairly common among pediatric patients who present to the ED with agitation.¹⁴ In a recent retrospective study, Kendrick et al¹⁴ found that among pediatric patients with agitation who were brought to the ED, benzodiazepines were the most commonly prescribed medications.

Other medications. Clonidine and guanfacine have been used off-label to treat agitation in children and adolescents, particularly among those with ADHD or autism. Some small pediatric trials have also shown their benefit in decreasing symptoms of aggression, impulsivity, and hyper-arousal in PTSD.³⁶ In addition to adverse effects that include but are not limited to lowered blood pressure, bradycardia, and risk of atrioventricular block, clinicians need to be vigilant for potentially serious rebound hypertension that may occur if doses of these medications are missed; this risk is greater with clonidine.

Diphenhydramine, in both oral and IM forms, has been used to treat agitation in children,³² but has also been associated with a paradoxical disinhibition reaction in pediatric patients²¹ and therefore should be used only sparingly and with caution. Diphenhydramine has anticholinergic properties, and may worsen delirium.¹⁵ Stimulant medications can help aggressive behavior in children and adolescents with ADHD.³⁷

Bottom Line

Agitation among children and adolescents has many possible causes. A combination of a comprehensive assessment and evidence-based, judicious treatment interventions can help prevent and manage agitation in this vulnerable population.

Aggression is the most common symptom for which SGAs are used among the pediatric population.²⁹ Careful and judicious weighing of the risks and benefits is warranted before using antipsychotic medications in a child or adolescent.

Externalizing disorders among children and adolescents tend to get treated with antipsychotics.²⁸ A Canadian study examining records of 6,916 children found that most children who had been prescribed risperidone received it for ADHD or conduct disorder, and most patients had not received laboratory testing for monitoring the antipsychotic medication they were taking.³¹ In a 2018 study examining medical records of 120 pediatric patients who presented to an ED in British Columbia with agitation, antipsychotics were the most commonly used medications for patients with autism spectrum disorder; most patients received at least 1 dose.¹⁴

For children and adolescents with agitation or aggression who were admitted to inpatient units, IM olanzapine and ziprasidone were found to exhibit similar efficacy when used to treat agitation.^14,21,32

Continue to: In case reports...

In case reports, a combination of olanzapine with CNS-suppressing agents has resulted in death. Therefore, do not combine olanzapine with agents such as benzodiazepines.²⁵ In a patient with a likely medical source of agitation, insufficient evidence exists to support the use of olanzapine, and additional research is needed.²⁵

Low-dose haloperidol has been found to be effective for delirium-related agitation in pediatric studies.¹⁵ Before initiating an antipsychotic for any child or adolescent, review the patient’s family history for reports of early cardiac death and the patient’s own history of cardiac symptoms, palpitations, syncope, or prolonged QT interval. Monitor for QT prolongation. Among commonly used antipsychotics, the risk of QT prolongation is higher with IV administration of haloperidol and with ziprasidone. Studies show that compared with oral or IM haloperidol, the IV formulation has a higher risk of increased QTc interval, torsades de pointes, and sudden death.³³ The FDA recommends continuous cardiac monitoring in adults receiving IV haloperidol. Data for its safety in children and adolescents are insufficient.

A few studies have found risperidone to be efficacious for treating ODD and conduct disorder; however, this use is off-label, and its considerable adverse effect and risk profile needs to be weighed against the potential benefit.⁸

Antipsychotic polypharmacy should be avoided because of the higher risk of adverse effects and interactions, and a lack of robust, controlled studies evaluating the safety of using antipsychotics for non-FDA-approved indications in children and adolescents.⁷ All patients who receive antipsychotics require monitoring for extrapyramidal symptoms, tardive dyskinesia, neuroleptic malignant syndrome, orthostatic hypotension, sedation, metabolic syndrome, and other potential adverse effects. Patients receiving risperidone need to have their prolactin levels monitored periodically, and their parents should be made aware of the potential for hyperprolactinemia and other adverse effects. Aripiprazole and quetiapine may increase the risk of suicidality.

Antiepileptics. A meta-analysis of 7 randomized controlled trials examining the use of antiepileptic medications (valproate, lamotrigine, levetiracetam, and topiramate) in children with autism spectrum disorder found no significant difference between placebo and these medications for addressing agitation.³⁴

Continue to: In a retrospective case series...

In a retrospective case series of 30 pedi­atric patients with autism spectrum disorder who were given oxcarbazepine, Douglas et al³⁵ found that 47% of participants experienced significant improvement in irritability/agitation. However, 23% of patients reported significant adverse effects leading to discontinuation. Insufficient evidence exists for the safety and efficacy of oxcarbazepine in this population.³⁵

Benzodiazepines. The use of benzodiazepines in pediatric patients has been associated with paradoxical disinhibition reactions, particularly in children with autism and other developmental or cognitive disabilities or delays.²¹ There is a lack of data on the safety and efficacy of long-term use of benzodiazepines in children, especially in light of these patients’ developing brains, the risk of cognitive impairment, and the potential for dependence with long-term use. Despite this, some studies show that the use of benzodiazepines is fairly common among pediatric patients who present to the ED with agitation.¹⁴ In a recent retrospective study, Kendrick et al¹⁴ found that among pediatric patients with agitation who were brought to the ED, benzodiazepines were the most commonly prescribed medications.

Other medications. Clonidine and guanfacine have been used off-label to treat agitation in children and adolescents, particularly among those with ADHD or autism. Some small pediatric trials have also shown their benefit in decreasing symptoms of aggression, impulsivity, and hyper-arousal in PTSD.³⁶ In addition to adverse effects that include but are not limited to lowered blood pressure, bradycardia, and risk of atrioventricular block, clinicians need to be vigilant for potentially serious rebound hypertension that may occur if doses of these medications are missed; this risk is greater with clonidine.

Diphenhydramine, in both oral and IM forms, has been used to treat agitation in children,³² but has also been associated with a paradoxical disinhibition reaction in pediatric patients²¹ and therefore should be used only sparingly and with caution. Diphenhydramine has anticholinergic properties, and may worsen delirium.¹⁵ Stimulant medications can help aggressive behavior in children and adolescents with ADHD.³⁷

Bottom Line

Agitation among children and adolescents has many possible causes. A combination of a comprehensive assessment and evidence-based, judicious treatment interventions can help prevent and manage agitation in this vulnerable population.

Managing agitation—verbal and/or motor restlessness that often is accompanied by irritability and a predisposition to aggression or violence—can be challenging in any patient, but particularly so in children and adolescents. In the United States, the prevalence of children and adolescents presenting to an emergency department (ED) for treatment of psychiatric symptoms, including agitation, has been on the rise.^1,2

Similar to the multitude of causes of fever, agitation among children and adolescents has many possible causes.³ Because agitation can pose a risk for harm to others and/or self, it is important to manage it proactively. Other than studies that focus on agitation in pediatric anesthesia, there is a dearth of studies examining agitation and its treatment in children and adolescents. There is also a scarcity of training in the management of acute agitation in children and adolescents. In a 2017 survey of pediatric hospitalists and consultation-liaison psychiatrists at 38 academic children’s hospitals in North America, approximately 60% of respondents indicated that they had received no training in the evaluation or management of pediatric acute agitation.⁴ In addition, approximately 54% of participants said they did not screen for risk factors for pediatric agitation, even though 84% encountered the condition at least once a month, and as often as weekly.⁴

This article reviews evidence on the causes and treatments of agitation in children and adolescents. For the purposes of this review, child refers to a patient age 6 to 12, and adolescent refers to a patient age 13 to 17.

Identifying the cause

Addressing the underlying cause of agitation is essential. It’s also important to manage acute agitation while the underlying cause is being investigated in a way that does not jeopardize the patient’s emotional or physical safety.

Agitation in children or teens can be due to psychiatric causes such as autism, attention-deficit/hyperactivity disorder (ADHD), or posttraumatic stress disorder (PTSD), or due to medical conditions such as delirium, traumatic brain injury, or other conditions (Table 1).

In a 2005 study of 194 children with agitation in a pediatric post-anesthesia care unit, pain (27%) and anxiety (25%) were found to be the most common causes of agitation.³ Anesthesia-related agitation was a less common cause (11%). Physiologic anomalies were found to be the underlying cause of agitation in only 3 children in this study, but were undiagnosed for a prolonged period in 2 of these 3 children, which highlights the importance of a thorough differential diagnosis in the management of agitation in children.³

Assessment of an agitated child should include a comprehensive history, physical exam, and laboratory testing as indicated. When a pediatric patient comes to the ED with a chief presentation of agitation, a thorough medical and psychiatric assessment should be performed. For patients with a history of psychiatric diagnoses, do not assume that the cause of agitation is psychiatric.

Continue to: Psychiatric causes

Autism spectrum disorder. Children and teens with autism often feel overwhelmed due to transitions, changes, and/or sensory overload. This sensory overload may be in response to relatively subtle sensory stimuli, so it may not always be apparent to parents or others around them.

Research suggests that in general, the ability to cope effectively with emotions is difficult without optimal language development. Due to cognitive/language delays and a related lack of emotional attunement and limited skills in recognizing, expressing, or coping with emotions, difficult emotions in children and adolescents with autism can manifest as agitation.

Attention-deficit/hyperactivity disorder. Children with ADHD may be at a higher risk for agitation, in part due to poor impulse control and limited coping skills. In addition, chronic negative feedback (from parents, teachers, or both) may contribute to low self-esteem, mood symptoms, defiance, and/or other behavioral difficulties. In addition to standard pharmacotherapy for ADHD, treatment involves parent behavior modification training. Setting firm yet empathic limits, “picking battles,” and implementing a developmentally appropriate behavioral plan to manage disruptive behavior in children or adolescents with ADHD can go a long way in helping to prevent the emergence of agitation.

Posttraumatic stress disorder. In some young children, new-onset, unexplained agitation may be the only sign of abuse or trauma. Children who have undergone trauma tend to experience confusion and distress. This may manifest as agitation or aggression, or other symptoms such as increased anxiety or nightmares.⁵ Trauma may be in the form of witnessing violence (domestic or other); experiencing physical, sexual, and/or emotional abuse; or witnessing/experiencing other significant threats to the safety of self and/or loved ones. Re-establishing (or establishing) a sense of psychological and physical safety is paramount in such patients.⁶ Psychotherapy is the first-line modality of treatment in children and adolescents with PTSD.⁶ In general, there is a scarcity of research on medication treatments for PTSD symptoms among children and adolescents.⁶

Oppositional defiant disorder/conduct disorder. Oppositional defiant disorder (ODD) can be comorbid with ADHD. The diagnosis of ODD requires a pervasive pattern of anger, defiance, vindictiveness, and hostility, particularly towards authority figures. However, these symptoms need to be differentiated from the normal range of childhood behavior. Occasionally, children learn to cope maladaptively through disruptive behavior or agitation. Although a parent or caregiver may see this behavior as intentionally malevolent, in a child with limited coping skills (whether due to young age, developmental/cognitive/language/learning delays, or social communication deficits) or one who has witnessed frequent agitation or aggression in the family environment, agitation and disruptive behavior may be a maladaptive form of coping. Thus, diligence needs to be exercised in the diagnosis of ODD and in understanding the psychosocial factors affecting the child, particularly because impulsiveness and uncooperativeness on their own have been found to be linked to greater likelihood of prescription of psychotropic medications from multiple classes.⁷ Family-based interventions, particularly parent training, family therapy, and age-appropriate child skills training, are of prime importance in managing this condition.⁸ Research shows that a shortage of resources, system issues, and cultural roadblocks in implementing family-based psychosocial interventions also can contribute to the increased use of psychotropic medications for aggression in children and teens with ODD, conduct disorder, or ADHD.⁸ The astute clinician needs to be cognizant of this before prescribing.

Continue to: Hallucinations/psychosis

Hallucinations/psychosis. Hallucinations (whether from psychiatric or medical causes) are significantly associated with agitation.⁹ In particular, auditory command hallucinations have been linked to agitation. Command hallucinations in children and adolescents may be secondary to early-onset schizophrenia; however, this diagnosis is rare.¹⁰ Hallucinations can also be an adverse effect of amphetamine-based stimulant medications in children and adolescents. Visual hallucinations are most often a sign of an underlying medical disorder such as delirium, occipital lobe mass/infection, or drug intoxication or withdrawal. Hallucinations need to be distinguished from the normal, imaginative play of a young child.¹⁰

Bipolar mania. In adults, bipolar disorder is a primary psychiatric cause of agitation. In children and adolescents, the diagnosis of bipolar disorder can be complex and requires careful and nuanced history-taking. The risks of agitation are greater with bipolar disorder than with unipolar depression.^11,12

Disruptive mood dysregulation disorder. Prior to DSM-5, many children and adolescents with chronic, non-episodic irritability and severe outbursts out of proportion to the situation or stimuli were given a diagnosis of bipolar disorder. These symptoms, in combination with other symptoms, are now considered part of disruptive mood dysregulation disorder when severe outbursts in a child or adolescent occur 3 to 4 times a week consistently, for at least 1 year. The diagnosis of disruptive mood dysregulation disorder requires ruling out other psychiatric and medical conditions, particularly ADHD.¹³

Substance intoxication/withdrawal. Intoxication or withdrawal from substances such as alcohol, stimulant medications, opioids, methamphetamines, and other agents can lead to agitation. This is more likely to occur among adolescents than children.¹⁴

Adjustment disorder. Parental divorce, especially if it is conflictual, or other life stressors, such as experiencing a move or frequent moves, may contribute to the development of agitation in children and adolescents.

Continue to: Depression

Depression. In children and adolescents, depression can manifest as anger or irritability, and occasionally as agitation.

Medical causes

Delirium. Refractory agitation is often a manifestation of delirium in children and adolescents.¹⁵ If unrecognized and untreated, delirium can be fatal.¹⁶ Therefore, it is imperative that clinicians routinely assess for delirium in any patient who presents with agitation.

Because a patient with delirium often presents with agitation and visual or auditory hallucinations, the medical team may tend to assume these symptoms are secondary to a psychiatric disorder. In this case, the role of the consultation-liaison psychiatrist is critical for guiding the medical team, particularly to continue a thorough exploration of underlying causes while avoiding polypharmacy. Noise, bright lights, frequent changes in nursing staff or caregivers, anticholinergic or benzodiazepine medications, and frequent changes in schedules should be avoided to prevent delirium from occurring or getting worse.¹⁷ A multidisciplinary team approach is key in identifying the underlying cause and managing delirium in pediatric patients.

Traumatic brain injury. Agitation may be a presenting symptom in youth with traumatic brain injury (TBI).¹⁸ Agitation may present often in the acute recovery phase.¹⁹ There is limited evidence on the efficacy and safety of pharmacotherapy for agitation in pediatric patients with TBI.¹⁸

Autoimmune conditions. In a study of 27 patients with anti-N-methyl-d-aspartate receptor encephalitis, Mohammad et al²⁰ found that agitation was a common symptom.

Continue to: Medication-induced/iatrogenic

Medication-induced/iatrogenic. Agitation can be an adverse effect of medications such as amantadine (often used for TBI),¹⁸ atypical antipsychotics,²¹ selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors.

Infection. Agitation can be a result of encephalitis, meningitis, or other infectious processes.²²

Metabolic conditions. Hepatic or renal failure, diabetic ketoacidosis, and thyroid toxicosis may cause agitation in children or adolescents.²²

Start with nonpharmacologic interventions

Few studies have examined de-escalation techniques in agitated children and adolescents. However, verbal de-escalation is generally viewed as the first-line technique for managing agitation in children and adolescents. When feasible, teaching and modeling developmentally appropriate stress management skills for children and teens can be a beneficial preventative strategy to reduce the incidence and worsening of agitation.²³

Clinicians should refrain from using coercion.²⁴ Coercion could harm the therapeutic alliance, thereby impeding assessment of the underlying causes of agitation, and can be particularly harmful for patients who have a history of trauma or abuse. Even in pediatric patients with no such history, coercion is discouraged due to its punitive connotations and potential to adversely impact a vulnerable child or teen.

Continue to: Establishing a therapeutic rapport...

Establishing a therapeutic rapport with the patient, when feasible, can facilitate smoother de-escalation by offering the patient an outlet to air his/her frustrations and emotions, and by helping the patient feel understood.²⁴ To facilitate this, ensure that the patient’s basic comforts and needs are met, such as access to a warm bed, food, and safety.²⁵

The psychiatrist’s role is to help uncover and address the underlying reason for the patient’s agony or distress. Once the child or adolescent has calmed, explore potential triggers or causes of the agitation.

There has been a significant move away from the use of restraints for managing agitation in children and adolescents.²⁶ Restraints have a psychologically traumatizing effect,²⁷ and have been linked to life-threatening injuries and death in children.²⁴

Pharmacotherapy: Proceed with caution

There are no FDA-approved medications for the treatment of agitation in the general pediatric population, and any medication use in this population is off-label. There is also a dearth of research examining the safety and efficacy of using psychotropic medications for agitation in pediatric patients. Because children and adolescents are more susceptible to adverse effects and risks associated with the use of psychotropic medications, special caution is warranted. In general, pharmacologic interventions are not recommended without the use of psychotherapy-based modalities.

In the past, the aim of using medications to treat patients with agitation was to put the patient to sleep.²⁵ This practice did not help clinicians to assess for underlying causes, and was often accompanied by a greater risk of adverse effects and reactions.²⁴ Therefore, the goal of medication treatment for agitation is to help calm the patient instead of inducing sleep.²⁵

Continue to: Pharmacotherapy should...

Pharmacotherapy should be used only when behavioral interventions have been unsuccessful. Key considerations for using psychotropic medications to address agitation in children and adolescents are summarized in Table 2.²⁵

Antipsychotics, particularly second-generation antipsychotics (SGAs), have been commonly used to manage acute agitation in children and adolescents, and there has been an upswing in the use of these medications in the United States in the last several years.²⁸ Research indicates that males, children and adolescents in foster care, and those with Medicaid have been the more frequent youth recipients of SGAs.²⁹ Of particular concern is the prevalence of antipsychotic use among children younger than age 6. In the last few decades, there has been an increase in the prescription of antipsychotics for children younger than age 6, particularly for disruptive behavior and aggression.³⁰ In a study of preschool-age Medicaid patients in Kentucky, 70,777 prescriptions for SGAs were given to 6,915 children <6 years of age; 73% of these prescriptions were for male patients.³⁰ Because there is a lack of controlled studies examining the safety and efficacy of SGAs among children and adolescents, especially with long-term use, further research is needed and caution is warranted.²⁸

The FDA has approved risperidone (for patients age 5 to 16) and oral aripiprazole (for patients age 6 to 17) for treating irritability related to autism spectrum disorder; irritability can contribute to or exacerbate agitation. The FDA has also approved several antipsychotic medications for treating schizophrenia or bipolar disorder in adolescents of varying ages. However, SGAs have also been found to be used commonly among young patients who do not meet criteria for autism, schizophrenia, or bipolar disorder. Aggression is the most common symptom for which SGAs are used among the pediatric population.²⁹ Careful and judicious weighing of the risks and benefits is warranted before using antipsychotic medications in a child or adolescent.

Externalizing disorders among children and adolescents tend to get treated with antipsychotics.²⁸ A Canadian study examining records of 6,916 children found that most children who had been prescribed risperidone received it for ADHD or conduct disorder, and most patients had not received laboratory testing for monitoring the antipsychotic medication they were taking.³¹ In a 2018 study examining medical records of 120 pediatric patients who presented to an ED in British Columbia with agitation, antipsychotics were the most commonly used medications for patients with autism spectrum disorder; most patients received at least 1 dose.¹⁴

In case reports, a combination of olanzapine with CNS-suppressing agents has resulted in death. Therefore, do not combine olanzapine with agents such as benzodiazepines.²⁵ In a patient with a likely medical source of agitation, insufficient evidence exists to support the use of olanzapine, and additional research is needed.²⁵

Low-dose haloperidol has been found to be effective for delirium-related agitation in pediatric studies.¹⁵ Before initiating an antipsychotic for any child or adolescent, review the patient’s family history for reports of early cardiac death and the patient’s own history of cardiac symptoms, palpitations, syncope, or prolonged QT interval. Monitor for QT prolongation. Among commonly used antipsychotics, the risk of QT prolongation is higher with IV administration of haloperidol and with ziprasidone. Studies show that compared with oral or IM haloperidol, the IV formulation has a higher risk of increased QTc interval, torsades de pointes, and sudden death.³³ The FDA recommends continuous cardiac monitoring in adults receiving IV haloperidol.

LJUBLJANA, SLOVENIA – A high body mass index in pregnant women who receive a seasonal influenza vaccine doesn’t impair their vaccine response; indeed, it might actually improve their seroconversion rate, Michelle Clarke reported at the annual meeting of the European Society for Paediatric Infectious Diseases.

Bruce Jancin/MDedge News

She presented a prospective cohort study of 90 women vaccinated against influenza during pregnancy, 24 of whom had a BMI of 30 kg/m² or more. The impetus for the study was the investigators’ understanding that influenza in pregnancy carries an increased risk of severe complications, obesity is a known risk factor for more severe episodes of influenza, and vaccine responses could potentially be adversely affected by obesity, either because of the associated inflammatory state and altered cytokine profile or inadequate vaccine delivery via the intramuscular route. Yet the impact of obesity on vaccine responses in pregnancy has been unclear.

Blood samples obtained before and 1 month after vaccination showed similarly high-titer postvaccination seropositivity rates against influenza B, H3N2, and H1N1 regardless of the women’s weight status. Indeed, the seropositivity rate against all three influenza viruses was higher in the obese subgroup, by a margin of 92%-74%. Also, postvaccination geometric mean antibody titers were significantly higher in the obese group. Particularly impressive was the difference in H1N1 seroconversion, defined as a fourfold increase in titer 28 days after vaccination: 79% versus 55%, noted Ms. Clarke of the University of Adelaide.

Of note, influenza vaccination in the first trimester resulted in a significantly lower seropositive antibody rate than vaccination in the second or third trimesters. The implication is that gestational age at vaccination, regardless of BMI, may be an important determinant of optimal vaccine protection for mothers and their newborns. However, this tentative conclusion requires confirmation in an independent larger sample, because the patient numbers in the study were small: Seropositive antibodies to all three vaccine antigens were documented in just 7 of 12 women (58%) vaccinated in the first trimester, compared with 47 of 53 (89%) vaccinated in the second trimester and 18 of 25 (72%) in the third.

Ms. Clarke reported having no financial conflicts regarding the study, which was supported by the Women’s and Children’s Hospital Research Foundation.

For children who are or are at risk of being overweight or obese, weight-based teasing was associated with further weight and fat gain, according to Natasha A. Schvey, PhD, of the Uniformed Services University of the Health Sciences, Bethesda, Md., and her associates.

BananaStock / Getty Images Plus

The investigators conducted a longitudinal, observational study of 110 children who were either in the 85th body mass index (BMI) percentile or greater or had two parents with a BMI of at least 25 kg/m². Children were recruited between July 12, 1996, and July 6, 2009, administered the Perception of Teasing Scale at baseline and during follow-up, and followed for up to 15 years. Children were aged a mean of 12 years at baseline, and attended an average of nine visits.

At baseline, 53% of children were overweight, with overweight being more common in girls and in non-Hispanic whites. A total of 62% of children who were overweight at baseline reported at least one incidence of weight-based teasing (WBT), compared with 21% of children at risk. WBT at baseline was associated with BMI throughout the study (P less than .001). In addition, children who reported more WBT showed a steeper gain in BMI (P = .007). Overall, children who reported high levels of WBT had 33% greater gains in BMI per year than those with no WBT.

Fat mass was associated with WBT in a similar manner, but to an increased extent, as children who reported high levels of WBT gained 91% more fat per year than those with no WBT.

“As adolescence marks a critical period for the study of weight gain, it will be important to further explore the effects of WBT and weight‐related pressures on indices of weight and health throughout development and to identify both risk and protective factors. The present findings ... may provide a foundation upon which to initiate clinical pediatric interventions to determine whether reducing WBT affects weight and fat gain trajectory,” the investigators concluded.

The study was supported by a grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The investigators did not report any conflicts of interest.

For children who are or are at risk of being overweight or obese, weight-based teasing was associated with further weight and fat gain, according to Natasha A. Schvey, PhD, of the Uniformed Services University of the Health Sciences, Bethesda, Md., and her associates.

The investigators conducted a longitudinal, observational study of 110 children who were either in the 85th body mass index (BMI) percentile or greater or had two parents with a BMI of at least 25 kg/m². Children were recruited between July 12, 1996, and July 6, 2009, administered the Perception of Teasing Scale at baseline and during follow-up, and followed for up to 15 years. Children were aged a mean of 12 years at baseline, and attended an average of nine visits.

At baseline, 53% of children were overweight, with overweight being more common in girls and in non-Hispanic whites. A total of 62% of children who were overweight at baseline reported at least one incidence of weight-based teasing (WBT), compared with 21% of children at risk. WBT at baseline was associated with BMI throughout the study (P less than .001). In addition, children who reported more WBT showed a steeper gain in BMI (P = .007). Overall, children who reported high levels of WBT had 33% greater gains in BMI per year than those with no WBT.

BALTIMORE – Experiencing panic-fear during asthma exacerbations predicted several beneficial outcomes in Mexican and Puerto Rican children with asthma, according to new research.

Tara Haelle/MDedge News

“When kids are anxious specifically during their asthma attacks, that can be a good thing because it means that they’re more vigilant,” lead author Jonathan M. Feldman, PhD, of the Albert Einstein College of Medicine’s Children’s Hospital at Montefiore and of Yeshiva University in the New York said in an interview. “They may be more likely to react during the early stages of an attack, and they may be more likely to be using self-management strategies at home and using their controller medications on a daily basis.”

He said pediatric providers can ask their patients with asthma how they feel during asthma attacks, such as whether they ever feel scared or worried.

“If a kid says no, not at all, then I would be concerned as a provider because they may not be paying attention to their asthma symptoms and they may not be taking it seriously,” Dr. Feldman said.

Past research has suggested that “illness-specific panic-fear” – the amount of anxiety someone experiences during asthma exacerbations – helps adults develop adaptive asthma management strategies, so Dr. Feldman and his colleagues examined the phenomenon as a potential protective factor in children. They shared their findings at the annual meeting of the Pediatric Academic Societies.

The research focused on Puerto Rican (n = 79) and Mexican (n = 188) children because of the substantial disparity in asthma prevalence and control between these two different Latino populations. Puerto Rican children have the highest asthma prevalence and morbidity among American children, whereas Mexican children have the lowest rates.

The 267 participants, aged 5-12 years, included 110 children from two inner-city hospitals in the New York and 157 children from two school-based health clinics and a Breathmobile in Phoenix. Nearly all the Arizona children were Mexican, and most (71%) of the Bronx children were Puerto Rican.

The authors collected the following measures at baseline and at 3, 6, 9, and 12 months follow-up: spirometry (forced expiratory volume in 1 second [FEV₁]), Childhood Asthma Control Test (CACT) for children 5-11 years old, the Asthma Control Test (ACT) for 12-year-olds, adherence to inhaled corticosteroids (ICS), and acute health care utilizations (clinic sick visits, ED visits, and hospitalizations).

The authors also queried patients on four illness-specific panic-fear measures from the Childhood Asthma Symptoms Checklist: how often they felt frightened, panicky, afraid of being alone, and afraid of dying during an asthma attack (Likert 1-5 scale).

Mexican children reported higher levels of illness-specific panic-fear at the start of the study. They also tended to have lower severity of asthma, better asthma control, and better adherence to ICS, compared with Puerto Rican children.

Also at baseline, the Mexican children’s caregivers tended to be younger, poorer, and more likely to be married and to speak Spanish. The Puerto Rican caregivers, on the other hand, had a higher educational level, including 61% high school graduates, and had more depressive symptoms on the Center for Epidemiologic Studies Depression Scale (CES-D).

One-year data revealed several links between baseline reports of panic-fear and better outcomes. Mexican children who reported experiencing panic-fear at baseline were more likely to have higher FEV₁ measures at 1 year of follow-up than were those who didn’t experience panic-fear (P = .02). Similarly, Puerto Rican children initially reporting panic-fear had better asthma control at 1 year, compared with those who didn’t report panic-fear (P = .007).

The researchers reported their effect sizes in terms of predicted variance in a model that accounted for the child’s age, sex, asthma duration, asthma severity, social support, acculturation, health care provider relationship, and number of family members with asthma. The model also factored in the caregiver’s age, sex, marital status, poverty level, education, and depressive symptoms.

For example, in their model, experiencing panic-fear accounted for 67% of the variance in FEV₁ levels in Mexican children and 53% of the variance in asthma control in Puerto Rican children.

Less acute health care utilization also was associated with children’s baseline levels of illness-specific panic-fear. In the model, 12% of the variance in acute health care utilization among Mexican children (P = .03) and 41% of the variance among Puerto Rican children (P = .02) was explained by child-reported panic-fear. No association was seen with medication adherence.

Although caregivers’ reports of children feeling panic-fear were linked to better FEV₁ outcomes in Mexican children (P = .02), the association was only slightly significant in Puerto Rican children (P = .05). Caregiver reports of children’s panic-fear were not associated with asthma control, acute health care utilization, or medication adherence.

“Providers should be aware that anxiety focused on asthma may be beneficial and facilitate adaptive asthma management strategies,” the authors concluded.

The research was funded by the National Institutes of Health. The authors reported no relevant financial disclosures.

LJUBLJANA, SLOVENIA – Pediatricians in the south of England are so concerned about the recent national increase in the diagnosis of syphilis in adults and its ramifications for neonates that they’ve ditched the traditional TORCH newborn screen because the acronym doesn’t specifically remind clinicians to think about congenital syphilis, Mildred A. Iro, MD, PhD, said at the annual meeting of the European Society for Paediatric Infectious Diseases.

Bruce Jancin/MDedge News

“We recommend a relabeling of the TORCH screen to ‘the congenital infection screen’ in order to include syphilis, which is now our local practice,” explained Dr. Iro of the University of Southampton (England).

She highlighted salient features of three recent cases of congenital syphilis managed at Southampton Children’s Hospital.

“The key message that we’d like to share is that we just need to be more aware about congenital syphilis. Retest mothers if their risk factor status changes, and test suspected infants and children,” Dr. Iro said.

As a practical matter, however, even though current guidelines recommend retesting mothers whose risk factor status becomes heightened following an initial negative syphilis serology result early in pregnancy, clinicians often are unaware that a mother’s risk status has changed. And retesting all mothers during pregnancy isn’t attractive from a cost-benefit standpoint. This makes scrupulous screening of newborns all the more important. And yet TORCH, which stands for Toxoplasmosis, Other, Rubella, Cytomegalovirus, and Herpes infections, isn’t an acronym that promotes awareness of congenital syphilis, a disease which occupies an obscure position in TORCH under the “O” for “Other” heading. That’s why the term “congenital infection screen” has become the new norm in the south of England, she explained.

However, one pediatrician who didn’t consider congenital infection screen to be an improvement in terminology over TORCH had an alternative suggestion, which struck a favorable chord with his fellow audience members: Simply change the acronym to TORCHS, with the S standing for syphilis.

Dr. Iro noted that two of the three affected children were diagnosed at age 7-8 weeks. The third wasn’t diagnosed until age 15 months, when the mother tested positive for syphilis in a subsequent pregnancy. As is typical of the disease known as “the great masquerader,” while all three of the affected children were unwell early in infancy, they presented with a wide range of symptoms. Among the more prominent features were prolonged irritability, respiratory distress, odd rashes, anemia, hepatomegaly, and tachypnea. One infant had reduced movement and pain in one arm.

All three children underwent extensive testing. None had neurosyphilis. All achieved good outcomes on standard guideline-directed therapy.

As for the mothers, they were aged 19, 21, and 23 years when diagnosed with syphilis. All were Caucasian, and antenatal blood testing was negative in all three. None were retested during pregnancy, even though two of them had a male partner or former partner who was positive for syphilis, and the partner of the third disclosed to her that he had sex with men.

At diagnosis, all three women had a strongly positive Treponema pallidum particle agglutination assay, a high rapid plasma reagin, and a positive syphilis IgM assay.

Dr. Iro reported having no financial conflicts regarding her presentation.

As I watched my grandson and his team warm up for their Saturday morning lacrosse game, a long parade of mostly purple-shirted adults and children of all ages began to weave its way around the periphery of the athletic field complex. A quick reading of the hand-lettered and machine-printed shirts made it clear that I was watching a charity walk for cystic fibrosis. There must have been several hundred walkers strolling by, laughing and chatting with one another. It lent a festive atmosphere to the park. I suspect that for most of the participants this was not their first fundraising event for cystic fibrosis.

Salima Senyavskaya/iStock Unreleased

The motley mix of marchers probably included several handfuls of parents of children with cystic fibrosis. I wonder how many of those parents realized how fortunate they were. Cystic fibrosis isn’t a great diagnosis. But at least it is a diagnosis, and with the diagnosis comes a community.

Reading a front-page article on DNA testing in a recent Wall Street Journal issue had primed me to reconsider how even an unfortunate diagnosis can be extremely valuable for a family (“The Unfulfilled Promise of DNA Testing,” by Amy Dockser Marcus, May 18, 2019).The focus of the article was on the confusion and disappointment that are the predictable consequences of our current inability to accurately correlate genetic code “mistakes” with phenotypic abnormalities. Of course there have been a few successes, but we aren’t even close to the promise that many have predicted in the wake of sequencing the human genome. The family featured in the article has a ridden roller coaster ride through two failed attributions of genetic syndromes that appeared to provide their now 8-year-old daughter with a diagnosis for her epilepsy and developmental delay.

In each case, the mother had searched out other families with children who shared the same genetic code errors. She formed support groups and created foundations to promote research for these rare disorders only to learn that her daughter didn’t really fit into the phenotype exhibited by the other children. As the article indicates this mother had “found a genetic home, only to feel that she no longer belonged.” She had made “intense friendships” and for “2 years, the community was her main emotional support.” Since the second diagnosis has evaporated, she has struggled with whether to remain with that community, having already left one behind. She has been encouraged to stay involved by another mother whose son does have the diagnosis. Understandably, she is still seeking the correct diagnosis, and I suspect will form or join a new community when she finds it.

We all want to belong to a community. Having a diagnosis, even if there is no reasonable hope for cure in the near future, is the ticket into that community. And with that ticket comes the opportunity to share the frustrations and difficulties unique to children with that diagnosis, and the comfort that there are other people who look, behave, and feel the way we do. We hear repeatedly about the value of diversity and how wonderful it is to be all inclusive. And certainly we should continue to be as accepting as we can of people who are different. But the truth is that we will always fall short because we seem to be hardwired to notice what is different. And the power of the longing to belong is often stronger than our will to be inclusive.

The revolution that resulted in the disappearance of the label “mental retardation” and the widespread adoption of the diagnosis of autism are examples of how a community can form around a diagnosis. But not every child who is labeled as autistic will actually fit the diagnosis. Yet even a less-than-perfect attribution can provide a place where a family and a patient can feel that they belong.

Reading a front-page article on DNA testing in a recent Wall Street Journal issue had primed me to reconsider how even an unfortunate diagnosis can be extremely valuable for a family (“The Unfulfilled Promise of DNA Testing,” by Amy Dockser Marcus, May 18, 2019).The focus of the article was on the confusion and disappointment that are the predictable consequences of our current inability to accurately correlate genetic code “mistakes” with phenotypic abnormalities. Of course there have been a few successes, but we aren’t even close to the promise that many have predicted in the wake of sequencing the human genome. The family featured in the article has a ridden roller coaster ride through two failed attributions of genetic syndromes that appeared to provide their now 8-year-old daughter with a diagnosis for her epilepsy and developmental delay.

In each case, the mother had searched out other families with children who shared the same genetic code errors. She formed support groups and created foundations to promote research for these rare disorders only to learn that her daughter didn’t really fit into the phenotype exhibited by the other children. As the article indicates this mother had “found a genetic home, only to feel that she no longer belonged.” She had made “intense friendships” and for “2 years, the community was her main emotional support.” Since the second diagnosis has evaporated, she has struggled with whether to remain with that community, having already left one behind. She has been encouraged to stay involved by another mother whose son does have the diagnosis. Understandably, she is still seeking the correct diagnosis, and I suspect will form or join a new community when she finds it.

We all want to belong to a community. Having a diagnosis, even if there is no reasonable hope for cure in the near future, is the ticket into that community. And with that ticket comes the opportunity to share the frustrations and difficulties unique to children with that diagnosis, and the comfort that there are other people who look, behave, and feel the way we do. We hear repeatedly about the value of diversity and how wonderful it is to be all inclusive. And certainly we should continue to be as accepting as we can of people who are different. But the truth is that we will always fall short because we seem to be hardwired to notice what is different. And the power of the longing to belong is often stronger than our will to be inclusive.

The revolution that resulted in the disappearance of the label “mental retardation” and the widespread adoption of the diagnosis of autism are examples of how a community can form around a diagnosis. But not every child who is labeled as autistic will actually fit the diagnosis. Yet even a less-than-perfect attribution can provide a place where a family and a patient can feel that they belong.

As I watched my grandson and his team warm up for their Saturday morning lacrosse game, a long parade of mostly purple-shirted adults and children of all ages began to weave its way around the periphery of the athletic field complex. A quick reading of the hand-lettered and machine-printed shirts made it clear that I was watching a charity walk for cystic fibrosis. There must have been several hundred walkers strolling by, laughing and chatting with one another. It lent a festive atmosphere to the park. I suspect that for most of the participants this was not their first fundraising event for cystic fibrosis.

Researchers have found they can screen pediatric cancer patients for genetic alterations and match those patients to appropriate targeted therapies.

Thus far, 24% of the patients screened have been matched and assigned to a treatment, and 10% have been enrolled on treatment protocols.

The patients were screened and matched as part of the National Cancer Institute–Children’s Oncology Group Pediatric MATCH (Molecular Analysis for Therapy Choice) trial.

Results from this trial are scheduled to be presented at the annual meeting of the American Society of Clinical Oncology.

Donald Williams Parsons, MD, PhD, of Baylor College of Medicine in Houston, Tex., presented some results at a press briefing in advance of the meeting. “[T]he last 10 years have been an incredible time in terms of learning more about the genetics and underlying molecular basis of both adult and pediatric cancers,” Dr. Parsons said.

He pointed out, however, that it is not yet known if this information will be useful in guiding the treatment of pediatric cancers. Specifically, how many pediatric patients can be matched to targeted therapies, and how effective will those therapies be?

The Pediatric MATCH trial (NCT03155620) was developed to answer these questions. Researchers plan to enroll at least 1,000 patients in this trial. Patients are eligible if they are 1-21 years of age and have refractory or recurrent solid tumors, non-Hodgkin lymphomas, or histiocytic disorders.

After patients are enrolled in the trial, their tumor samples undergo DNA and RNA sequencing, and the results are used to match each patient to a targeted therapy. At present, the trial can match patients to one of 10 drugs:

• larotrectinib (targeting NTRK fusions).
• erdafitinib (targeting FGFR1/2/3/4).
• tazemetostat (targeting EZH2 or members of the SWI/SNF complex).
• LY3023414 (targeting the PI3K/MTOR pathway).
• selumetinib (targeting the MAPK pathway).
• ensartinib (targeting ALK or ROS1).
• vemurafenib (targeting BRAF V600 mutations).
• olaparib (targeting defects in DNA damage repair).
• palbociclib (targeting alterations in cell cycle genes).
• ulixertinib (targeting MAPK pathway mutations).

Early results

From July 2017 through December 2018, 422 patients were enrolled in the trial. The patients had more than 60 different diagnoses, including brain tumors, sarcomas, neuroblastoma, renal and liver cancers, and other malignancies.

The researchers received tumor samples from 390 patients, attempted sequencing of 370 samples (95%), and completed sequencing of 357 samples (92%).

A treatment target was found in 112 (29%) patients, 95 (24%) of those patients were assigned to a treatment, and 39 (10%) were enrolled in a protocol. The median turnaround time from sample receipt to treatment assignment was 15 days.

“In addition to the sequencing being successful, the patients are being matched to the different treatments,” Dr. Parsons said. He added that the study is ongoing, so more of the matched and assigned patients will be enrolled in protocols in the future.

Dr. Parsons also presented results by tumor type. A targetable alteration was identified in 26% (67/255) of all non–central nervous system solid tumors, 13% (10/75) of osteosarcomas, 50% (18/36) of rhabdomyosarcomas, 21% (7/33) of Ewing sarcomas, 25% (9/36) of other sarcomas, 19% (5/26) of renal cancers, 16% (3/19) of carcinomas, 44% (8/18) of neuroblastomas, 43% (3/7) of liver cancers, and 29% (4/14) of “other” tumors.

Drilling down further, Dr. Parsons presented details on specific alterations in one cancer type: astrocytomas. Targetable alterations were found in 74% (29/39) of astrocytomas. This includes NF1 mutations (18%), BRAF V600E (15%), FGFR1 fusions/mutations (10%), BRAF fusions (10%), PIK3CA mutations (8%), NRAS/KRAS mutations (5%), and other alterations.

“Pretty remarkably, in this one diagnosis, there are patients who have been matched to nine of the ten different treatment arms,” Dr. Parsons said. “This study is allowing us to evaluate targeted therapies – specific types of investigational drugs – in patients with many different cancer types, some common, some very rare. So, hopefully, we can study these agents and identify signals of activity where some of these drugs may work for our patients.”

The Pediatric MATCH trial is sponsored by the National Cancer Institute. Dr. Parsons has patents, royalties, and other intellectual property related to genes discovered through sequencing of several adult cancer types.
