Pediatrics

It’s a typically busy Friday and the doctor is running 20 minutes behind schedule. He enters the next exam room and the sight of the patient makes him forget the apology he had prepared.

The 10 month old looks miserable. Red eyes. Snot dripping from his nose. A red rash that extends from his face and involves most of the chest, arms, and upper thighs.

“When did this start?” he asks the mother as he searches for a surgical mask in the cabinet next to the exam table.

“Two days after we returned from our vacation in France,” the worried young woman replies. “Do you think it could be measles?”

Between Jan. 1 and Aug. 8, 2019, 1,182 cases of measles had been confirmed in the United States. That’s more than three times the number of cases reported in all of 2018, and the highest number of cases reported in a single year in more than a quarter century. While 75% of the cases this year have been linked to outbreaks in New York, individuals from 30 states have been affected.

Given the widespread nature of the outbreak, it makes sense for every ambulatory office to have a plan for managing exposures to infectious diseases including measles. With measles in particular, time is limited to deliver effective postexposure prophylaxis and prevent the spread of measles in the community, making it difficult to develop a plan on the fly.

Schedule strategically. You don’t want a patient with measles hanging out in your waiting room. According to the American Academy of Pediatrics, measures to prevent the transmission of contagious infectious agents in ambulatory facilities begin at the time the visit is scheduled. When there is measles transmission in the community, consider using a standardized script when scheduling patients that includes questions about fever, rash, other symptoms typical for measles, and possible exposures. Some offices will have procedures in place that can be adapted to care for patients with suspected measles. When a patient presents for suspected chicken pox, do you advise them to come at the end of the day to minimize exposures? Enter through a side door? Perform a car visit?

Triage promptly. Mask patients with fever and rash, move to a private room, and close the door.

Once measles is suspected, only health care personnel who are immune to measles should enter the exam room. According to the Centers for Disease Control and Prevention, presumptive evidence of measles immunity in health care providers is written documentation of vaccination with two doses of live measles or MMR vaccine administered at least 28 days apart, laboratory evidence of immunity (that is, positive measles IgG), laboratory confirmation of disease, or birth before 1957.

Even though health care providers born before 1957 are presumed to have had the disease at some point and have traditionally been considered immune, the CDC suggests that health care facilities consider giving these individuals two doses of MMR vaccine unless they have prior laboratory confirmation of disease immunity. Do you know who in your office is immune or would you need to scramble if you had an exposure?

When measles is suspected, health care personnel should wear an N-95 if they have been fit tested and the appropriate mask is available. Practically, most ambulatory offices do not stock N-95 masks and the next best choice is a regular surgical mask.

Order the recommended tests to confirm the diagnosis, but do not wait for the results to confirm the diagnosis. The CDC recommends testing serum for IgM antibodies and sending a throat or nasopharyngeal swab to look for the virus by polymerase chain reaction testing. Measles virus also is shed in the urine so collecting a urine specimen for testing may increase the chances of finding the virus. Depending on where you practice, the tests may take 3 days or more to result. Contact your local health department as soon as you consider a measles diagnosis.

Discharge patients home or transferred to a higher level of care if this is necessary as quickly as possible. Fortunately, most patients with measles do not require hospitalization. Do not send patients to the hospital simply for the purpose of laboratory testing if this can be accomplished quickly in your office or for evaluation by other providers. This just creates the potential for more exposures. If a patient does require higher-level care, provider-to-provider communication about the suspected diagnosis and the need for airborne isolation should take place.

Keep the door closed. Once a patient with suspected measles is discharged from a regular exam room, the door should remain closed, and it should not be used for at least 1 hour. Remember that infectious virus can remain in the air for 1-2 hours after a patient leaves an area. The same is true for the waiting room.

Develop the exposure list. In general, patients and family members who were in the waiting room at the same time as the index patient and up to 1-2 hours after the index patient left are considered exposed. Measles is highly contagious and 9 out of 10 susceptible people who are exposed will develop disease. How many infants aged less than 1 year might be in your waiting room at any given time? How many immunocompromised patients or family members? Public health authorities can help determine who needs prophylaxis.

Don’t get anxious and start testing everyone for measles, especially patients who lack typical signs and symptoms or exposures. Ordering a test in a patient who has a low likelihood of measles is more likely to result in a false-positive test than a true-positive test. False-positive measles IgM tests can be seen with some viral infections, including parvovirus and Epstein-Barr. Some rheumatologic disorders also can contribute to false-positive tests.

Review your office procedure for vaccine counseling. The 10 month old with measles in the opening vignette should have been given an MMR vaccine before travel. The vaccine is recommended for infants aged 6-11 months who are traveling outside the United States, but it doesn’t count toward the vaccine series. Reimmunize young travelers at 12-15 months and again at 4-6 years. The CDC has developed a toolkit that contains resources for taking to parents about vaccines. It is available at https://www.cdc.gov/measles/toolkit/healthcare-providers.html.

Nebraska’s Department of Education recommended in a guidance that children be allowed to possess and use sunscreen products in school and at school-sponsored events, according to an Aug. 2 release from the American Society for Dermatologic Surgery.

American Society for Dermatologic Surgery Association (ASDSA)

The department’s guidance is based on model legislation developed by the SUNucate Coalition, which was created by the American Society for Dermatologic Surgery Association and “works to address barriers to sunscreen use in school and camps and promote sun-safe behavior.” The coalition was created in 2016 because of reports that some U.S. schools had banned sunscreen products as part of broader medication bans because of these products’ classification as an over-the-counter medication.

Twenty-three other states have moved to lift such bans; these states were joined by Arkansas, Connecticut, Illinois, Maine, Minnesota, Nevada, and now Nebraska in 2019 alone. The District of Columbia, Massachusetts, New Jersey, and Rhode Island are expected to follow suit.

LJUBLJANA, SLOVENIA – A prospective international surveillance study has provided new insights into the surprisingly substantial clinical burden of viral meningitis caused by enteroviruses and human parechoviruses in young infants, Seilesh Kadambari, MBBS, PhD, said in his ESPID Young Investigator Award Lecture at the annual meeting of the European Society for Paediatric Infectious Diseases.

This comprehensive study captured all cases of laboratory-confirmed enterovirus (EV) and human parechovirus (HPeV) meningitis in infants less than 90 days old seen by pediatricians in the United Kingdom and Ireland during a 13-month period starting in July 2014, a time free of outbreaks. Dr. Kadambari, a pediatrician at the University of Oxford (England), was first author of the study. It was for this project, as well as his earlier studies shedding light on congenital viral infections, that he received the Young Investigator honor.

Among the key findings of the U.K./Ireland surveillance study: The incidence of EV/HPeV meningitis was more than twice that of bacterial meningitis in the same age group and more than fivefold higher than that of group B streptococcal meningitis, the No. 1 cause of bacterial meningitis in early infancy. Moreover, more than one-half of infants with EV/HPeV meningitis had low levels of inflammatory markers and no cerebrospinal fluid pleocytosis, which underscores the importance of routinely testing the cerebrospinal fluid for viral causes of meningitis in such patients using modern molecular tools such as multiplex polymerase chain reaction, according to Dr. Kadambari.

“Also, not a single one of the patients with EV/HPeV meningitis had a secondary bacterial infection – and that has important implications for management of our antibiotic stewardship programs,” he observed.

The study (Arch Dis Child. 2019 Jun;104(6):552-7) identified 668 cases of EV meningitis and 35 of HPeV meningitis, for an incidence of 0.79 and 0.04 per 1,000 live births, respectively. The most common clinical presentations were those generally seen in meningitis: fever, irritability, and reduced feeding. Circulatory shock was present in 43% of the infants with HPeV and 27% of the infants with EV infections.

Of infants with EV meningitis, 11% required admission to an intensive care unit, as did 23% of those with HPeV meningitis. Two babies with EV meningitis died and four others had continued neurologic complications at 12 months of follow-up. In contrast, all infants with HPeV survived without long-term sequelae.

Reassuringly, none of the 189 infants who underwent formal hearing testing had sensorineural hearing loss.

The surveillance study data have played an influential role in evidence-based guidelines for EV diagnosis and characterization published by the European Society of Clinical Virology (J Clin Virol. 2018 Apr;101:11-7).

An earlier study led by Dr. Kadambari documented a hefty sevenfold increase in the rate of laboratory-confirmed viral meningo-encephalitis in England and Wales during 2004-2013 across all age groups (J Infect. 2014 Oct;69[4]:326-32).

He attributed this increase to improved diagnosis of viral forms of meningitis through greater use of polymerase chain reaction. The study, based upon National Health Service hospital records, showed that more than 90% of all cases of viral meningo-encephalitis in infants less than 90 days old were caused by EV, a finding that prompted the subsequent prospective U.K./Ireland surveillance study.

Dr. Kadambari closed by noting the past decade had seen a greatly improved ability to diagnose congenital viral infections, but those improvements are not good enough.

“In the decade ahead, we hope to improve the management of this poorly understood group of infections,” the pediatrician promised.

Planned efforts include a cost-effectiveness analysis of a cytomegalovirus vaccine, an ESPID-funded research project aimed at identifying which EV/HPeV strains are most responsible for outbreaks and isolated severe disease, and gaining insight into the host-immunity factors associated with a proclivity to develop EV/HPeV meningitis in early infancy.

Dr. Kadambari reported having no financial conflicts regarding his studies, which was funded largely by Public Health England and university grants.

With the perinatal history of prolonged labor and prolonged rupture of membranes, the diagnosis of halo scalp ring was made. This occurs secondary to prolonged pressure of the baby’s scalp with the mother’s pelvic bones, uterus, or cervical area, which causes decreased blood flow to the area, secondary ischemic damage, and in some cases scarring and hair loss.¹

With the perinatal history of prolonged labor and prolonged rupture of membranes, the diagnosis of halo scalp ring was made. This occurs secondary to prolonged pressure of the baby’s scalp with the mother’s pelvic bones, uterus, or cervical area, which causes decreased blood flow to the area, secondary ischemic damage, and in some cases scarring and hair loss.¹

SEATTLE – Levine Children’s Hospital, in Charlotte, N.C., dropped its central line–associated bloodstream infection rate from 1.13 per 1,000 line days to 0.67 in just a few months, with a mix of common sense steps and public accountability.

Levine Children’s was at about the 50th percentile for CLABSIs, compared with other children’s hospitals, but dropped to the 10th percentile after the changes. There were 21 CLABSIs in 2017, but only 12 in 2018. The hospital went 6 straight months without a CLABSI after the changes were made. The efforts saved about $300,000 and 63 patient days.

“We really had great success,” said Kayla S. Koch, MD, a pediatric hospitalist at Levine Children’s, who presented the findings at Pediatric Hospital Medicine.

Hospital units had been working to reduce CLABSIs, but they were each doing their own thing. “Many of our units were already dabbling, so we just sort of brought them together. We standardized the process and got everyone on the same page,” said copresenter Ketan P. Nadkarni, MD, also a pediatric hospitalist at Levine Children’s.

It wasn’t hard to get buy-in. “I don’t think the units were aware that everyone was doing it differently,” and were on board once the problem was explained. Also, using the same approach throughout the hospital made it easier for nurses and physicians moving between units, he said.

Each morning, the nurse supervisor and patient nurse would partner up at the bedside to check that central venous lines were set up correctly. They examined the alcohol disinfectant caps to make sure they were clean; determined that children were getting chlorhexidine gluconate baths; checked the dressings for bleeding and soiling; noted in the electronic medical record why the patient had a central line; and discussed with hospitalists if it were still needed. Problems were addressed immediately.

These quality processes were all tracked on wall racks placed in plain sight on each unit, including the neonatal and pediatric ICUs. Each central line patient had a card that listed what needed to be done, with a green stripe on one side and a red stripe on the other. If everything was done right, the green side faced out; if even one thing was done wrong, the red side was displayed, for all to see. It brought accountability to the process, the presenters said at the meeting sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

The wall rack also had the central line audit schedule, plus diagrams that showed every failed item, the reason for it, and the unit’s compliance rate. Anyone walking by could see at a glance how the unit was doing that day and overall.

The number of dressing options was reduced from 10 to 2, a SorbaView SHIELD and a Tegaderm-like dressing, which made it easier to standardize the efforts. A protocol also was put in place to reinforce oozing dressings, instead of automatically changing them. “We were doing too many changes,” Dr. Koch said.

Compliance with the bundle was almost 90%. Staff “really got into it, and it was great to see,” she said.

The “initial success was almost unexpected, and so dramatic.” The goal now is to sustain the improvements, and roll them out to radiology and other places were central lines are placed, Dr. Nadkarni said.

There was no external funding, and the investigators had no disclosures.

Bacteria on children’s skin was similar to their mothers’ and affected by factors that included method of delivery and breastfeeding in a study of 154 children aged 10 years and younger.

Understanding the skin microbiome is important to determine whether certain bacteria may be helpful or harmful, but skin microbiome studies in children are limited, wrote Ting Zhu of Fudan University, Shanghai, China, and colleagues.

In a study published in the Journal of Investigative Dermatology, the researchers compared the skin microbiota of the 158 children aged 1-10 years and 50 mothers using 16S rRNA gene amplicon sequencing after collecting study samples from three skin areas: face, calf, and ventral forearm. The samples were pooled into 36 groups based on age, gender, and skin site.

“We observed significant differences in alpha diversity and the most prevalent taxa and identified factors that contributed to variation at each site,” the authors reported.

Overall, the “alpha diversity” – a measure of microbial diversity used in microbiome studies – of the skin microbiome increased with age, with the highest alpha diversity seen in the 10-year-olds (n = 28), notably on the face, but differences in alpha diversity between skin sites were seen only in the 1-year-olds (n = 26). Overall, the most commonly identified bacterial phyla at all skin sites in children were Proteobacteria (42%), Firmicutes (25%), Actinobacteria (13%), and Bacteroidetes (11%). In the three sites, the genera with high relative abundance (over 3%) included Streptococcus (13%), Enhydrobacter (6%), and Propionibacterium (5%). Of these, Streptococcus and Granulicatella showed negative linear correlations with age.

The researchers found significant differences between the bacterial communities of 10-year-olds delivered by Cesarean section and those delivered vaginally, particularly in the facial samples; however the difference wasn’t observed among face samples taken from 1-year-olds, according to the authors. They found significant variation in bacteria in calf samples based on whether the children were fed breast milk, formula, or a combination.

When the researchers examined the correlations between mother/child pairs, they found that the relative abundance of most bacteria in the children were more similar to their mothers than to unrelated adults, and they found the strongest correlations for the genera Deinococcus, Microbacterium, Chryseobacterium, Klebsiella, and Enhydrobacter. The relationships between the bacterial communities of mothers and children may be influenced by the shared living environment, topical products, and daily diet, they noted.

The study findings were limited by not controlling for certain variables, including daily diet, choice of topical products, bathing habits, and daily variation in environmental factors, the researchers wrote. However, the results show “that the skin microbiome is strongly affected by the surrounding microenvironment and that the alpha diversity of the skin microbiome increases during childhood,” they concluded.

The study was fully funded by Johnson & Johnson International, and several coauthors are employees of that company. Lead author Ms. Zhu had no financial conflicts to disclose.

High levels of enterovirus (EV) peptides were found in the cerebrospinal fluid (CSF) and serum samples of individuals with acute flaccid myelitis (AFM) that were not present in a variety of control individuals, according to the results of a small study of patients with and without AFM published online in mBio.

CDC

In 2018, CSF samples from AFM patients were investigated by viral-capture high-throughput sequencing. These CSF and serum samples, as well as those from multiple controls, were tested for antibodies to human EVs using peptide microarrays, according to Nischay Mishra, PhD, of Columbia University, New York, and colleagues.

Although EV RNA was confirmed in CSF from only 1 adult AFM case and 1 non-AFM case, antibodies to EV peptides were present in 11 of 14 AFM patients (79%), which was a significantly higher rate than in control groups, including non-AFM patients (1 of 5, or 20%), children with Kawasaki disease (0 of 10), and adults with non-AFM CNS diseases (2 of 11, 18%), according to the authors.

In addition, 6 of 14 (43%) CSF samples and 8 of 11 (73%) serum samples from AFM patients were immunoreactive to an EV-D68–specific peptide, whereas samples from the three control groups were not immunoreactive in either CSF or sera. Previous studies have suggested that infection with EV-D68 and EV-A71 may contribute to AFM.

“There have been 570 confirmed cases since CDC began tracking AFM in August 2014. AFM outbreaks were reported to the CDC in 2014, 2016, and 2018. AFM affects the spinal cord and is characterized by the sudden onset of muscle weakness in one or more limbs. Spikes in AFM cases, primarily in children, have coincided in time and location with outbreaks of EV-D68 and a related enterovirus, EV-A71,” according to an NIH media advisory discussing the article.

In particular, as the study authors point out, a potential link to EV-D68 has also been based on the presence of viral RNA in some respiratory and stool specimens and the observation that EV-D68 infection can result in spinal cord infection.

“While other etiologies of AFM continue to be investigated, our study provides further evidence that EV infection may be a factor in AFM. In the absence of direct detection of a pathogen, antibody evidence of pathogen exposure within the CNS can be an important indicator of the underlying cause of disease,” Dr. Mishra and his colleagues added.

“These initial results may provide avenues to further explore how exposure to EV may contribute to AFM as well as the development of diagnostic tools and treatments,” the researchers concluded.

The study was funded by the National Institutes of Health. The authors reported that they had no competing financial interests.

Prophylactic treatment with bisphosphonates could significantly improve bone mineral density (BMD) in children and adolescents receiving steroids for chronic rheumatic disease, a study has found.

A paper published in EClinicalMedicine reported the outcomes of a multicenter, double-dummy, double-blind, placebo-controlled trial involving 217 patients who were receiving steroid therapy for juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile dermatomyositis, or juvenile vasculitis. The patients were randomized to risedronate, alfacalcidol, or placebo, and all of the participants received 500 mg calcium and 400 IU vitamin D daily.

Lumbar spine and total body (less head) BMD increased in all groups, but the greatest increase was seen in patients treated with risedronate.

After 1 year, lumbar spine and total body (less head) BMD had increased in all groups, compared with baseline, but the greatest increase was seen in patients who had been treated with risedronate.

The lumbar spine areal BMD z score remained the same in the placebo group (−1.15 to −1.13), decreased from −0.96 to −1.00 in the alfacalcidol group, and increased from −0.99 to −0.75 in the risedronate group.

The change in z scores was significantly different between placebo and risedronate groups, and between risedronate and alfacalcidol groups, but not between placebo and alfacalcidol.

“The acquisition of adequate peak bone mass is not only important for the young person in reducing fracture risk but also has significant implications for the development of osteoporosis in later life, if peak bone mass is suboptimal,” wrote Madeleine Rooney, MBBCH, from the Queens University of Belfast, Northern Ireland, and associates.

There were no significant differences between the three groups in fracture rates. However, researchers were also able to compare Genant scores for vertebral fractures in 187 patients with pre- and posttreatment lateral spinal x-rays. That showed that the 54 patients in the placebo arm and 52 patients in the alfacalcidol arm had no change in their baseline Genant score of 0 (normal). However, although all 53 patients in the risedronate group had a Genant score of 0 at baseline, at 1-year follow-up, 2 patients had a Genant score of 1 (mild fracture), and 1 patient had a score of 3 (severe fracture).

In biochemical parameters, researchers saw a drop in parathyroid hormone in the placebo and alfacalcidol groups, but a rise in the risedronate group. However, the authors were not able to see any changes in bone markers that might have indicated which patients responded better to treatment.

Around 90% of participants in each group were also being treated with disease-modifying antirheumatic drugs. The rates of biologic use were 10.5% in the placebo group, 23.9% in the alfacalcidol group, and 10.1% in the risedronate group.

The researchers also noted a 7% higher rate of serious adverse events in the risedronate group, but emphasized that there were no differences in events related to the treatment.

In an accompanying editorial, Ian R. Reid, MBBCH, of the department of medicine, University of Auckland (New Zealand) noted that the study was an important step toward finding interventions for the prevention of steroid-induced bone loss in children. “The present study indicates that risedronate, and probably other potent bisphosphonates, can provide bone preservation in children and young people receiving therapeutic doses of glucocorticoid drugs, whereas alfacalcidol is without benefit. The targeted use of bisphosphonates in children and young people judged to be at significant fracture risk is appropriate. However, whether preventing loss of bone density will reduce fracture incidence remains to be established.”

The study was funded by Arthritis Research UK. No conflicts of interest were declared.

The lumbar spine areal BMD z score remained the same in the placebo group (−1.15 to −1.13), decreased from −0.96 to −1.00 in the alfacalcidol group, and increased from −0.99 to −0.75 in the risedronate group.

The change in z scores was significantly different between placebo and risedronate groups, and between risedronate and alfacalcidol groups, but not between placebo and alfacalcidol.

“The acquisition of adequate peak bone mass is not only important for the young person in reducing fracture risk but also has significant implications for the development of osteoporosis in later life, if peak bone mass is suboptimal,” wrote Madeleine Rooney, MBBCH, from the Queens University of Belfast, Northern Ireland, and associates.

There were no significant differences between the three groups in fracture rates. However, researchers were also able to compare Genant scores for vertebral fractures in 187 patients with pre- and posttreatment lateral spinal x-rays. That showed that the 54 patients in the placebo arm and 52 patients in the alfacalcidol arm had no change in their baseline Genant score of 0 (normal). However, although all 53 patients in the risedronate group had a Genant score of 0 at baseline, at 1-year follow-up, 2 patients had a Genant score of 1 (mild fracture), and 1 patient had a score of 3 (severe fracture).

In biochemical parameters, researchers saw a drop in parathyroid hormone in the placebo and alfacalcidol groups, but a rise in the risedronate group. However, the authors were not able to see any changes in bone markers that might have indicated which patients responded better to treatment.

Around 90% of participants in each group were also being treated with disease-modifying antirheumatic drugs. The rates of biologic use were 10.5% in the placebo group, 23.9% in the alfacalcidol group, and 10.1% in the risedronate group.

The researchers also noted a 7% higher rate of serious adverse events in the risedronate group, but emphasized that there were no differences in events related to the treatment.

In an accompanying editorial, Ian R. Reid, MBBCH, of the department of medicine, University of Auckland (New Zealand) noted that the study was an important step toward finding interventions for the prevention of steroid-induced bone loss in children. “The present study indicates that risedronate, and probably other potent bisphosphonates, can provide bone preservation in children and young people receiving therapeutic doses of glucocorticoid drugs, whereas alfacalcidol is without benefit. The targeted use of bisphosphonates in children and young people judged to be at significant fracture risk is appropriate. However, whether preventing loss of bone density will reduce fracture incidence remains to be established.”

The study was funded by Arthritis Research UK. No conflicts of interest were declared.

Prophylactic treatment with bisphosphonates could significantly improve bone mineral density (BMD) in children and adolescents receiving steroids for chronic rheumatic disease, a study has found.

A paper published in EClinicalMedicine reported the outcomes of a multicenter, double-dummy, double-blind, placebo-controlled trial involving 217 patients who were receiving steroid therapy for juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile dermatomyositis, or juvenile vasculitis. The patients were randomized to risedronate, alfacalcidol, or placebo, and all of the participants received 500 mg calcium and 400 IU vitamin D daily.

Lumbar spine and total body (less head) BMD increased in all groups, but the greatest increase was seen in patients treated with risedronate.

BANGKOK – For a form of epilepsy treatment that’s been around since the 1920s, ketogenic diet therapy has lately been the focus of a surprising wealth of clinical research and development, Suvasini Sharma, MD, observed at the International Epilepsy Congress.

Bruce Jancin/MDedge News

This high-fat, low-carbohydrate diet is now well established as a valid and effective treatment option for children and adults with drug-refractory epilepsy who aren’t candidates for surgery. That’s about a third of all epilepsy patients. And as the recently overhauled pediatric ketogenic diet therapy (KDT) best practice consensus guidelines emphasize, KDT should be strongly considered after two antiepileptic drugs have failed, and even earlier for several epilepsy syndromes, noted Dr. Sharma, a pediatric neurologist at Lady Hardinge Medical College and Kalawati Saran Children’s Hospital in New Delhi, and a coauthor of the updated guidelines.

“The consensus guidelines recommend that you start thinking about the diet early, without waiting for every drug to fail,” she said at the congress, sponsored by the International League Against Epilepsy.

Among the KDT-related topics she highlighted were the recently revised best practice consensus guidelines; an expanding role for KDT in infants, critical care settings, and in epileptic encephalopathies; mounting evidence that KDT provides additional benefits beyond seizure control; and promising new alternative diet therapies. She also described the challenges of using KDT in a low-resource nation such as India, where most of the 1.3 billion people shop in markets where food isn’t packaged with the nutritional content labels essential to traditional KDTs, and low literacy is common.


 

KDT best practice guidelines

The latest guidelines, which include the details of standardized KDT protocols as well as a summary of recent translational research into mechanisms of action, replace the previous 10-year-old version. Flexibility is now the watchword. While the classic KDT was started as an inpatient intervention involving several days of fasting followed by multiday gradual reintroduction of calories, that approach is now deemed optional (Epilepsia Open. 2018 May 21;3[2]:175-92).

“By and large, the trend now is going to nonfasting initiation on an outpatient basis, but with more stringent monitoring,” according to Dr. Sharma.

The guidelines note that while the research literature shows that, on average, KDT results in about a 50% chance of at least a 50% reduction in seizure frequency in patients with drug-refractory epilepsy, there are a dozen specific conditions with 70% or greater responder rates: infantile spasms, tuberous sclerosis, epilepsy with myoclonic-atonic seizures, Dravet syndrome, glucose transporter 1 deficiency syndrome (Glut 1DS), pyruvate dehydrogenase deficiency (PDHD), febrile infection-related epilepsy syndrome (FIRES), super-refractory status epilepticus (SRSE), Ohtahara syndrome, complex I mitochondrial disorders, Angelman syndrome, and children with gastrostomy tubes. For Glut1DS and PDHD, KDTs should be considered the treatment of first choice.

Traditionally, KDTs weren’t recommended for children younger than age 2 years. There were concerns that maintaining ketosis and meeting growth requirements were contradictory goals. That’s no longer believed to be so. Indeed, current evidence shows that KDT is highly effective and well tolerated in infants with refractory epilepsy. European guidelines address patient selection, pre-KDT counseling, preferred methods of initiation and KDT discontinuation, and other key issues (Eur J Paediatr Neurol. 2016 Nov;20[6]:798-809).

The guidelines recognize four major, well-studied types of KDT: the classic long-chain triglyceride-centric diet; the medium-chain triglyceride diet; the more user-friendly modified Atkins diet; and low glycemic index therapy. Except in children younger than 2 years old, who should be started on the classic KDT, the consensus panel recommended that the specific KDT selected should be based on the family and child situation and the expertise at the local KDT center. Perceived differences in efficacy between the diets aren’t supported by persuasive evidence.
 

KDT benefits beyond seizure control

“Most of us who work in the diet scene are aware that patients often report increased alertness, and sometimes improved cognition,” said Dr. Sharma.

That subjective experience is now supported by evidence from a randomized, controlled trial. Dutch investigators who randomized 50 drug-refractory pediatric epilepsy patients to KDT or usual care documented a positive impact of the diet therapy on cognitive activation, mood, and anxious behavior (Epilepsy Behav. 2016 Jul;60:153-7).

More recently, a systematic review showed that while subjective assessments support claims of improved alertness, attention, and global cognition in patients on KDT for refractory epilepsy, structured neuropsychologic testing confirms the enhanced alertness but without significantly improved global cognition. The investigators reported that the improvements were unrelated to decreases in medication, the type of KDT or age at its introduction, or sleep improvement. Rather, the benefits appeared to be due to a combination of seizure reduction and direct effects of KDT on cognition (Epilepsy Behav. 2018 Oct;87:69-77).

There is also encouraging preliminary evidence of a possible protective effect of KDT against sudden unexpected death in epilepsy (SUDEP) in a mouse model (Epilepsia. 2016 Aug;57[8]:e178-82. doi: 10.1111/epi.13444).
 

The use of KDT in critical care settings

Investigators from the pediatric Status Epilepticus Research Group (pSERG) reported that 10 of 14 patients with convulsive refractory status epilepticus achieved EEG seizure resolution within 7 days after starting KDT. Moreover, 11 patients were able to be weaned off their continuous infusions within 14 days of starting KDT. Treatment-emergent gastroparesis and hypertriglyceridemia occurred in three patients (Epilepsy Res. 2018 Aug;144:1-6).

“It was reasonably well tolerated, but they started it quite late – a median of 13 days after onset of refractory status epilepticus. It should come much earlier on our list of therapies. We shouldn’t be waiting 2 weeks before going to the ketogenic diet, because we can diagnose refractory status epilepticus within 48 hours after arrival in the ICU most of the time,” Dr. Sharma said.

Austrian investigators have pioneered the use of intravenous KDT as a bridge when oral therapy is temporarily impossible because of status epilepticus, surgery, or other reasons. They reported that parental KDT with fat intake of 3.5-4 g/kg per day was safe and effective in their series of 17 young children with epilepsy (Epilepsia Open. 2017 Nov 16;3[1]:30-9).
 

The future: nonketogenic diet therapies

KDT in its various forms is just too demanding and restrictive for some patients. Nonketotic alternatives are being explored.

Triheptanoin is a synthetic medium-chain triglyceride in the form of an edible, odorless, tasteless oil. Its mechanism of action is by anaplerosis: that is, energy generation via replenishment of the tricarboxylic acid cycle. After demonstration of neuroprotective and anticonvulsant effects in several mouse models, Australian investigators conducted a pilot study of 30- to 100-mL/day of oral triheptanoin as add-on therapy in 12 children with drug-refractory epilepsy. Eight of the 12 took triheptanoin for longer than 12 weeks, and 5 of those 8 experienced a sustained greater than 50% reduction in seizure frequency, including 1 who remained seizure free for 30 weeks. Seven children had diarrhea or other GI side effects (Eur J Paediatr Neurol. 2018 Nov;22[6]:1074-80).

Parisian investigators have developed a nonketotic, palatable combination of amino acids, carbohydrates, and fatty acids with a low ratio of fat to protein-plus-carbohydrates that provided potent protection against seizures in a mouse model. This suggests that the traditional 4:1 ratio sought in KDT isn’t necessary for robust seizure reduction (Sci Rep. 2017 Jul 14;7[1]:5496).

“This is probably going to be the future of nutritional therapy in epilepsy,” Dr. Sharma predicted.

She reported having no financial conflicts regarding her presentation.

PHILADELPHIA – U.S. children and teens who were hospitalized because of asthma had twice the rate of migraine headache when compared with a similar pediatric population without asthma. The finding is based on an analysis of more than 11 million U.S. pediatric hospitalizations over the course of a decade.

Among children and adolescents aged 3-21 years who were hospitalized for asthma, migraine rates were significantly higher among girls, adolescents, and whites, compared with boys, children aged 12 years or younger, and nonwhites, respectively, in a trio of adjusted analyses, Riddhiben S. Patel, MD, and associates reported in a poster at the annual meeting of the American Headache Society.

“Our hope is that, by establishing an association between childhood asthma and migraine, [these children] may be more easily screened for, diagnosed, and treated early by providers,” wrote Dr. Patel, a pediatric neurologist and headache specialist at the University of Mississippi, Jackson, and associates.

Their analysis used administrative billing data collected by the Kids’ Inpatient Database, maintained by the U.S. Healthcare Cost and Utilization Project. The project includes a representative national sample of about 3 million pediatric hospital discharges every 3 years. The study used data from 11,483,103 hospitalizations of children and adolescents aged 3-21 years during 2003, 2006, 2009, and 2012, and found an overall hospitalization rate of 0.8% billed for migraine. For patients also hospitalized with a billing code for asthma, the rate jumped to 1.36%, a 120% statistically significant relative increase in migraine hospitalizations after adjustment for baseline demographic differences, the researchers said.

Among the children and adolescents hospitalized with an asthma billing code, the relative rate of also having a billing code for migraine after adjustment was a statistically significant 80% higher in girls, compared with boys, a statistically significant 7% higher in adolescents, compared with children 12 years or younger, and was significantly reduced by a relative 45% rate in nonwhites, compared with whites.

The mechanisms behind these associations are not known, but could involve mast-cell degranulation, autonomic dysfunction, or shared genetic or environmental etiologic factors, the authors said.

Dr. Patel reported no relevant disclosures.

The finding is based on an analysis of more than 11 million U.S. pediatric hospitalizations over the course of a decade.

Among children and adolescents aged 3-21 years who were hospitalized for asthma, migraine rates were significantly higher among girls, adolescents, and whites, compared with boys, children aged 12 years or younger, and nonwhites, respectively, in a trio of adjusted analyses, Riddhiben S. Patel, MD, and associates reported in a poster at the annual meeting of the American Headache Society.

“Our hope is that, by establishing an association between childhood asthma and migraine, [these children] may be more easily screened for, diagnosed, and treated early by providers,” wrote Dr. Patel, a pediatric neurologist and headache specialist at the University of Mississippi, Jackson, and associates.

Their analysis used administrative billing data collected by the Kids’ Inpatient Database, maintained by the U.S. Healthcare Cost and Utilization Project. The project includes a representative national sample of about 3 million pediatric hospital discharges every 3 years. The study used data from 11,483,103 hospitalizations of children and adolescents aged 3-21 years during 2003, 2006, 2009, and 2012, and found an overall hospitalization rate of 0.8% billed for migraine. For patients also hospitalized with a billing code for asthma, the rate jumped to 1.36%, a 120% statistically significant relative increase in migraine hospitalizations after adjustment for baseline demographic differences, the researchers said.

Among the children and adolescents hospitalized with an asthma billing code, the relative rate of also having a billing code for migraine after adjustment was a statistically significant 80% higher in girls, compared with boys, a statistically significant 7% higher in adolescents, compared with children 12 years or younger, and was significantly reduced by a relative 45% rate in nonwhites, compared with whites.

The mechanisms behind these associations are not known, but could involve mast-cell degranulation, autonomic dysfunction, or shared genetic or environmental etiologic factors, the authors said.

Dr. Patel reported no relevant disclosures.
