One monoclonal dose gives preterm neonates season-long RSV protection
WASHINGTON – A single dose of a novel monoclonal antibody against a respiratory syncytial virus surface protein safely protected preterm infants against severe infections for 150 days during their first winter season in a randomized trial with more than 1,400 children.
One intramuscular injection of nirsevimab (also known as MEDI8897) administered to infants born at 29-35 weeks’ gestation at the start of the local respiratory syncytial virus (RSV) season (November in the Northern hemisphere) led to a 70% relative reduction in the rate of medically attended lower respiratory tract infections with RSV during the subsequent 150 days, compared with placebo, the study’s primary efficacy outcome, M. Pamela Griffin, MD, said at an annual scientific meeting on infectious diseases.
In a secondary efficacy measure, the rate of hospitalizations for RSV-caused lower respiratory tract infections, a single injection of nirsevimab dropped the incidence by 78%, relative to placebo. Both effects were statistically significant. The rate of total adverse events and serious adverse events was similar in the two treatment arms, reported Dr. Griffin, a clinical development lead with AstraZeneca.
These positive results for a single intramuscular injection of nirsevimab are the first findings from a series of studies aimed at getting the monoclonal antibody onto the U.S. market as a superior alternative to palivizumab (Synagis), which acts in a similar way to block RSV infection (albeit by targeting a different viral surface protein) but which requires administration every 30 days. This need for serial dosing of palivizumab in children younger than 1 year old for complete seasonal protection against RSV is probably a reason why the American Academy of Pediatrics, as well as other medical societies, have targeted using palivizumab only on certain types of high-risk infants: those born before 29 weeks’ gestational age, with chronic lung disease of prematurity, or with hemodynamically significant congenital heart disease (Pediatrics. 2014 Aug;134[2]:415-20). “It’s not feasible for most infants to come for five treatments during RSV season,” Dr. Griffin noted. A tweak in the structure of nirsevimab gives it a much longer blood half-life than palivizumab and allows a single dose to maintain efficacy for 5 months, the duration of RSV season.
“The big advantage of nirsevimab is one dose instead of five,” she said in an interview.
The study randomized 969 preterm infants to nirsevimab and 484 to placebo when the children averaged 3 months old and 4.5 kg. The incidence of the primary endpoint was 2.6% in the nirsevimab-treated infants and 9.5% in those who received placebo. The incidence of hospitalizations associated with an RSV lower respiratory tract infection was 0.8% in the nirsevimab group and 4.1% on placebo. Nirsevimab was equally effective regardless of RSV subtype, infant age, or sex. The rate of hypersensitivity reactions was low, less than 1%, and similar in the two treatment arms, as was the rate of detection of antidrug antibody, 3.8% with placebo and 5.6% with nirsevimab.
Two other large trials are underway to document the performance of nirsevimab in other types of infants. One study is examining the drug’s performance compared with placebo in term infants with a gestational age of at least 36 weeks, while another is comparing nirsevimab against a five-dose regimen of palivizumab in high-risk infants who are recommended to receive palivizumab by local medical societies. In the United States, this would be infants born at less than 29 weeks’ gestation, and those with either hemodynamically significant congenital heart disease or chronic lung disease of prematurity. In these studies, the researchers also will assess the cost effectiveness of nirsevimab relative to the costs for medical care needed by infants who receive comparator treatments, Dr. Griffin said.
The study was funded by AstraZeneca, the company developing nirsevimab. Dr. Griffin is an employee of and shareholder in AstraZeneca.

REPORTING FROM ID WEEK 2019
Inspector General: NIH must improve conflict of interest reviews
the Department of Health & Human Services’ Office of Inspector General reported.
In highlighting the improvement in a September 2019 report, “NIH has made strides in reviewing financial conflicts of interest in extramural research, but could do more,” the OIG noted that, in the past 10 years, “NIH has strengthened its reporting requirements and developed an online system for collecting, reviewing, and storing financial conflicts of interest (FCOIs) that institutions report. These changes resulted in improvements in how NIH tracks and reviews FCOIs that institutions report.”
That being said, OIG also highlighted some ongoing issues with NIH’s FCOI oversight.
“Across the three NIH Institutes and Centers (ICs) that we reviewed, staff differed in the level of scrutiny they applied to their review of FCOIs,” the report states.
For example, the report notes that 15 of the 25 ICs have written procedures related to FCOI reviews and the documentation shared by the three ICs showed different levels of detail and instruction.
“Only one of the three guidance documents provided IC staff with specific criteria aimed at standardizing the review of FCOIs,” the report stated. Two of the three ICs also reported using external resources to aid in the review.
Review times also varied significantly, with two of the three ICs reporting that they spend generally 5-30 minutes per review, while the third said staff spends several hours on reviews.
The OIG also reported that “NIH lacks quality assurance procedures in its review process. Specifically, NIH central management and the three ICs that we reviewed do not perform any systematic analyses or even ad hoc checks to determine whether staff accurately and consistently review reported FCOIs, and OIG found a small number of inconsistencies in the FCOI data that institutions reported, which might highlight the need for more oversight of the review process.”
The report notes that there is a process in place to provide oversight of ICs’ review of reported FCOIs, but there is no longer sufficient staff to continue this oversight.
The “OER [Office of Extramural Research] now relies on IC staff to seek guidance when needed and does not conduct regular oversight of the ICs. Similarly, none of the three ICs we reviewed perform quality checks to ensure the thoroughness or consistency of review by program officials. Staff members from one IC stated that while they do not conduct quality checks, the IC provides new program officials more guidance during their first few reviews.”
The HHS watchdog also noted that NIH cannot identify whether FCOIs involve foreign entities even though investigators must disclose financial interests from foreign investments.
“The HHS regulations on FCOI do not require institutions to designate whether FCOIs involve foreign entities, and NIH reported that it has no plans to expand these regulations to include such a requirement,” the OIG reported.
The OIG recommended that NIH perform periodic quality assurance reviews of FCOI information to ensure adequacy of oversight and suggested it use “information regarding foreign affiliations and support that it collects during the pre-award process to decide whether to revise its FCOI review process to address concerns regarding foreign influence.”

Sixty-five roses
Like many of you, my wife and I took the DNA plunge for fun and spit in the cup. She is genetically perfect, but I, however, am a carrier for alpha-1 anti-trypsin deficiency, hemochromatosis, and like 1 in 19 Irish people, cystic fibrosis. Plus, I was in the top 20% for Neanderthal genes.
My Y chromosome had traveled to the United States from Europe, where it had spent several hundred years in Ireland (in the house of Neal); wandering to Ireland from the Middle East, and originating in Siberia! Fascinating stuff.
away. It is hypothesized that the very-high-frequency deleterious genes have a survival advantage in the heterozygous state, coined the “heterozygote advantage.”
Alpha-1 antitrypsin deficiency allows the body to concentrate an inflammatory response in the lungs and liver, perhaps providing protection against tuberculosis (Am J Respir Crit Care Med. 2006 May 15;173[10]:1072-7).
Hemochromatosis allows for increased iron absorption attributable to decreased iron in a grain-based diet, and facilitates thyroid-stimulating hormone release in cold environments (Am J Phys Anthropol. 2016 May;160[1]:86-101).
Cystic fibrosis carriers are more resistant to diarrheal illness, particularly cholera and typhoid fever since they have only one exudative chloride channel to switch on. Their sputum is also thicker, interfering with microdroplet generation and spread of the bacilli to others.
This topic and learning of my CF carrier status bring to mind one of my patients. When doing skin exams, I sometimes ask patients about elaborate tattoos (not the obvious youthful misadventures). “Nice ink” I will say, and I wait and see if they want to elaborate. This particular patient was enthusiastic and explained that the elaborate floral design with roses on his right leg was in memory of his daughter. I asked what had happened, expecting a tragic car wreck, or perhaps cancer or a drug overdose. He cheerfully explained she had died of cystic fibrosis at age 21, a year after a lung transplant.
My eyes started to water. My patient was upbeat and said she had lived with gusto and survived long enough to buy him a triple gin and tonic at bar. She had always had a bright outlook, despite her debilitating and eventually fatal disease.
I had to ask more about the memorial tattoo. He explained that her initials were linked with his at the bottom of the bouquet of many, many roses. “Why roses?” I asked. “Well,” he said, “when she was little, she could not pronounce cystic fibrosis, so she always said, ‘My daddy says I have 65 roses.’ ”*
Oh boy. I had to go sit in my office, turn out the lights, and cry.

Primary periodic paralysis attacks reduced with long-term dichlorphenamide
AUSTIN, TEX. – Dichlorphenamide continues to reduce attacks from primary periodic paralysis (PPP) through 1 year with mild or moderate paresthesia and cognition-related adverse events, according to new research.
“These adverse events rarely resulted in discontinuation from the study and were sometimes managed by dichlorphenamide dose reductions,” concluded Nicholas E. Johnson, MD, of Virginia Commonwealth University, Richmond, and colleagues. “Reduction in dose was frequently associated with resolution of these events, suggesting a potential intervention to hasten resolution.” Dr. Johnson presented the findings in an abstract at the annual meeting of the American Association for Neuromuscular and Electrodiagnostic Medicine.
Dichlorphenamide (Keveyis) was approved by the Food and Drug Administration in 2015 for treating primary hyperkalemic and hypokalemic periodic paralysis and similar variants. The original hyperkalemic/hypokalemic PPP trial was a phase 3 randomized, double-blind, placebo-controlled trial that lasted 9 weeks and assessed the efficacy of dichlorphenamide in reducing PPP attacks and its adverse events. In the dichlorphenamide group, 47% experienced paresthesia, compared with 14% in the placebo group, and 19% experienced cognitive disorder, compared with 7% in the placebo.
In a 52-week open-label extension, participants who had been receiving the placebo switched to receiving 50 mg of dichlorphenamide twice daily. The intervention group continued with the dose they had been receiving when the 9-week double-blind phase ended. (During the initial intervention, they took either 50 mg twice daily or the dose they had at baseline for those taking it before the study began.)
The researchers then tracked rates of attacks and their severity over the next year – through week 61 after baseline – to compare these endpoints both within the intervention groups and between them.
Among the 63 predominantly white (84.1%) male (61.9%) adults who began the trial, 36 received dichlorphenamide and 27 received placebo. Just over two-thirds (68.3%) had hypokalemic PPP. Among the 47 patients (74.6%) who completed the open-label extension phase, 26 had been in the original dichlorphenamide group and 21 had been in the placebo group.
The median weekly attack rate in the dichlorphenamide group dropped from 1.75 at baseline to 0.06 at week 61 (median decrease 1.00, 93.8%; P less than .0001). In the placebo group that switched over to dichlorphenamide at week 9, the median weekly attack rate dropped from 3.00 at baseline to 0.25 at week 61 (median decrease 0.63, 75%; P = .01).
The median attack rate weighted for severity in the dichlorphenamide group dropped from 2.25 at baseline to 0.06 at week 61 (median decrease 2.25, 97.1%; P less than .0001). In the placebo group, it dropped from 5.88 to 0.50 (median decrease 1.69, 80.8%; P = .01).
No significant difference in median weekly attack rates and severity-weighted attack rates was found between the intervention groups through week 61.
Across all patients during the extension, 39.7% patients experienced at least one paresthesia adverse event, none of which were determined to be severe and resulting in one discontinuation.
A quarter of the participants (25.4%) experienced at least one cognition-related adverse event, and four patients (6.3%) discontinued because of these side effects. Most (14.3%) were mild with 7.9% reporting moderate and 3.2% reporting severe effects.

AUSTIN, TEX. – Dichlorphenamide continues to reduce attacks from primary periodic paralysis (PPP) through 1 year with mild or moderate paresthesia and cognition-related adverse events, according to new research.
“These adverse events rarely resulted in discontinuation from the study and were sometimes managed by dichlorphenamide dose reductions,” concluded Nicholas E. Johnson, MD, of Virginia Commonwealth University, Richmond, and colleagues. “Reduction in dose was frequently associated with resolution of these events, suggesting a potential intervention to hasten resolution.” Dr. Johnson presented the findings in an abstract at the annual meeting of the American Association for Neuromuscular and Electrodiagnostic Medicine.
Dichlorphenamide (Keveyis) was approved by the Food and Drug Administration in 2015 for treating primary hyperkalemic and hypokalemic periodic paralysis and similar variants. The original hyperkalemic/hypokalemic PPP trial was a phase 3 randomized, double-blind, placebo-controlled trial that lasted 9 weeks and assessed the efficacy of dichlorphenamide in reducing PPP attacks and its adverse events. In the dichlorphenamide group, 47% experienced paresthesia, compared with 14% in the placebo group, and 19% experienced cognitive disorder, compared with 7% in the placebo.
In a 52-week open-label extension, participants who had been receiving the placebo switched to receiving 50 mg of dichlorphenamide twice daily. The intervention group continued with the dose they had been receiving when the 9-week double-blind phase ended. (During the initial intervention, they took either 50 mg twice daily or the dose they had at baseline for those taking it before the study began.)
The researchers then tracked rates of attacks and their severity over the next year – through week 61 after baseline – to compare these endpoints both within the intervention groups and between them.
Among the 63 predominantly white (84.1%) male (61.9%) adults who began the trial, 36 received dichlorphenamide and 27 received placebo. Just over two-thirds (68.3%) had hypokalemic PPP. Among the 47 patients (74.6%) who completed the open-label extension phase, 26 had been in the original dichlorphenamide group and 21 had been in the placebo group.
The median weekly attack rate in the dichlorphenamide group dropped from 1.75 at baseline to 0.06 at week 61 (median decrease 1.00, 93.8%; P less than .0001). In the placebo group that switched over to dichlorphenamide at week 9, the median weekly attack rate dropped from 3.00 at baseline to 0.25 at week 61 (median decrease 0.63, 75%; P = .01).
The median attack rate weighted for severity in the dichlorphenamide group dropped from 2.25 at baseline to 0.06 at week 61 (median decrease 2.25, 97.1%; P less than .0001). In the placebo group, it dropped from 5.88 to 0.50 (median decrease 1.69, 80.8%; P = .01).

Patients with Charcot-Marie-Tooth disease describe wide range of care
AUSTIN, TEX. – Patients with Charcot-Marie-Tooth disease (CMT) receive a range of supportive care that includes physical therapy, surgery, medications, orthoses, and walking aids, according to patient-reported data presented at the annual meeting of the American Association of Neuromuscular and Electrodiagnostic Medicine. Patients describe approaches to CMT management that are broadly consistent with guidelines, researchers said.
“The range of different CMT treatments was wide,” reported Tjalf Ziemssen, MD, PhD, a researcher at Technische Universität Dresden in Germany, and colleagues. “ These results indicate that pain may have a substantial impact on people with CMT.”
The data also suggest that “lower-limb problems and mobility issues have a considerable impact on people with CMT,” they said.
CMT is a rare, progressive neuropathy that leads to distal muscle weakness, muscle atrophy, and sensory loss. There is no cure, and patients rely on supportive care. Until recently, few studies have assessed the impact of CMT on patients’ lives.
An ongoing, international, 2-year observational study is collecting data from adults with CMT. Patients report data via an app called CMT & Me.
To examine patient-reported treatment patterns and care standards for CMT in the United States and the United Kingdom, Dr. Ziemssen and colleagues analyzed data through Aug. 5, 2019, about 9.5 months into the study. Their interim analysis included data from 439 patients, including 222 patients in the United Kingdom and 217 in the United States.
More than 70% of participants visit a family doctor each year, and a similar proportion visit a neurologist. About 40% visit physical therapists, orthotists, or podiatrists. Other health care professionals seen by patients include occupational therapists (20%), orthopedic surgeons (nearly 20%), and pain specialists (about 15%).
About 70% of participants had received rehabilitation therapy such as physical therapy or occupational therapy, and about 70% had used medications, most frequently nonopioid analgesics (about 50%) and antidepressants (about 30%).
More than 80% used orthoses or walking aids, most commonly ankle or leg braces, insoles, or walking sticks.
In addition, about half of respondents had undergone a surgery for CMT. The most common procedures were osteotomy, hammertoe correction, and plantar fascia release.
Together, patients saw about a dozen types of health care professionals. “Small proportions of participants had visited each professional, which suggests that the care requirements of CMT patients are varied,” the researchers said.
The study was sponsored by Pharnext. Dr. Ziemssen and coauthors received compensation for participating in the study. Other coauthors are employees of Pharnext or Vitaccess, the company that developed the app used in the study.

Researchers identify common reasons for misdiagnosis of ALS
AUSTIN – Lack of upper motor neuron signs on examination, presence of sensory symptoms, and absence of tongue fasciculations are common causes of amyotrophic lateral sclerosis (ALS) misdiagnosis, according to an investigation presented at the annual meeting of the American Association of Neuromuscular and Electrodiagnostic Medicine.
Because its initial presenting symptoms vary, ALS can be difficult for clinicians to diagnose. A diagnostic error may prompt clinicians and patients to pursue ineffective and potentially harmful medical or surgical interventions. Research suggests that surgery, for example, hastens the progression of ALS.
Catherine Rodriguez, a medical student at University of Missouri in Columbia, and colleagues conducted a study to identify the clinical factors and types of cognitive errors that can result in misdiagnosis of ALS. The researchers analyzed electronic medical records of 88 patients with a diagnosis of ALS who were receiving treatment at the University of Missouri Hospital during 2011-2017 with at least 1 year of follow-up. They collected demographic information and clinical characteristics (e.g., ALS Functional Rating Scale and site of symptom onset) for each patient. If a patient received an incorrect diagnosis, Ms. Rodriguez and colleagues recorded the number of physicians he or she had seen, the incorrect diagnosis, the treatment, the type of diagnostic error, the clinical factors contributing to the misdiagnosis, and the type of physician who gave the incorrect diagnosis.
The investigators classed diagnostic errors according to the four categories of cognitive bias of the Patient Safety Network. The categories are availability heuristic (i.e., the diagnosis of a current patient is biased by the clinician’s experience with previous cases), anchoring heuristic (i.e., relying on the initial impression despite the emergence of evidence that may contradict it), framing effects (i.e., subtle cues and collateral information bias the diagnosis), and blind obedience (i.e., undue reliance on test results or expert opinion). Ms. Rodriguez and colleagues used Fisher’s exact test to perform a statistical analysis of the data.
Thirty-four (39%) of the 88 patients were female, and the populations average age was about 60 years. Eighty patients (91%) were white, six (7%) were black, and two (2%) were Hispanic. Twenty patients (23%) received an incorrect diagnosis. Common incorrect diagnoses included spinal abnormality, Bell’s palsy, myasthenia gravis, ulnar neuropathy, autoimmune motor neuropathy, and stroke.
The investigators observed significant differences in the reasons for misdiagnosis, depending on patient characteristics. Veterans were misdiagnosed because of the availability heuristic, while nonveterans were misdiagnosed because of the anchoring heuristic. Lower-limb onset was most commonly misdiagnosed because of the anchoring heuristic. Bulbar onset was most commonly misdiagnosed because of the availability heuristic. Surgical intervention was the most common treatment for an incorrect diagnosis.
The data serve as a reminder of the prevalence of cognitive biases, said Ms. Rodriguez. “Common things are common, so we tend to stick with those [diagnoses]. Especially with ALS, nobody wants to give anyone that diagnosis.” Clinicians should “recognize that incorrect diagnoses have equally bad outcomes for those patients,” she concluded.
The study was supported by a University of Missouri School of Medicine Summer Research Fellowship Program.

Robot-assisted, gamelike tool effective for classifying ADHD
A novel robot-assisted, gamelike test accurately classified ADHD type in elementary school–aged children, according to Mun-Taek Choi, PhD, and associates.
A total of 326 children in the third and fourth grades were included in the study, 35 of whom had been diagnosed with ADHD and 26 of whom were at risk. For the 10- to 12-minute test, participants followed a robot on a path across a numbered mat while stimuli were shown on a TV with both images and sound, and completed a task at each numbered square, reported Dr. Choi, of Sungkyunkwan University, Suwan, South Korea, and associates. The study was published in the Journal of Intelligent & Robotic Systems.
Inattentive and hyperactive-impulsive behavior was measured by the number of omission and commission errors. Response time and task completion time contributed to the measure of inattentive and hyperactive-impulsive behavior. Working memory deficits were measured as deviations in the prescribed route.
This figure improved over the course of the study as the tool learned more, indicating that generalization errors were not a serious issue for the tool, the investigators noted.
“Unlike conventional questionnaire-based tests, the robot-assisted test increases the accuracy of ADHD diagnosis by directly reflecting the quality of children’s behavior during the activity game with the robot involved in the action. Since the test obtains behavioral patterns and levels using robotic sensing technologies, it can reliably determine the three key elements of ADHD diagnosis: hyperactivity, inattentive behavior, and working memory,” the investigators wrote. Ultimately, Dr. Choi and associates wrote, the tool could help clinicians diagnose childhood ADHD.
The study was funded by the South Korean Ministry of Trade, Industry, & Energy. No disclosures were reported.

Psychodiagnostic testing services: The elusive quest for clinicians
Assessment psychologists should be colocated in specialty practices
Imagine the clinical care consequences if patients seen in specialty or primary care practices did not have ready access to laboratory, other medical tests, and/or consultative services deemed critical to quickly establishing diagnostic status and the development of an appropriate treatment plan. For instance, what would be the implications if a dentistry practice did not employ a dental hygienist; an otolaryngology group was not staffed with an audiologist; or a gastroenterology practice had no one available for digestive/nutritional consultation support.
Consider a neurologist who suspects that a patient has a potentially life-threatening brain condition, but the patient has to wait months for brain imaging or – even worse – is tasked to find their own provider for this diagnostic test only to be told that the neuroimaging service does not take their insurance and/or there are no available appointments for several months.
Situations of this kind would not be – and should not be – tolerated by medical professionals or their patients.
A common “real-world” scenario: After evaluation, a psychiatrist needs clarification regarding a possible subtle psychotic process, or, in another instance, suspects that there is an early degenerative cognitive change underlying recent changes in mood and personality. However, the psychiatrist has no dependable access to an assessment psychologist to assist in cases of this kind.
Patients are frequently told by psychiatrists and other physicians that they should have psychodiagnostic testing to arrive at a clearer picture of their clinical status and treatment needs. However, most medical practices, in particular, psychiatry, pediatrics, neurology, and neurosurgery, who see substantial numbers of patients who could benefit from testing, do not employ psychologists. When they do, many do not possess the requisite assessment skills to address the reason(s) for referral.
If the patient needing testing services is fortunate enough, he/she is referred to a well-trained psychologist within commuting distance who takes the patient’s insurance and is able to set up a timely appointment – an unlikely set of circumstances in today’s health care environment.
Some state psychological associations allow for a “matching service” of sorts in the form of announcements in the organization’s listserv, which reviews the referral and includes a back channel for psychologists to contact the patient regarding their availability for testing.
Over the past 2 decades, significant advancements have been made in the integration of primary and mental health care. Those need to continue to include colocating assessment psychologists in medical specialty practices, such as psychiatry, which make frequent referrals for psychodiagnostic testing or would like to but have no place to turn.

Assessment psychologists should be colocated in specialty practices
Assessment psychologists should be colocated in specialty practices
Imagine the clinical care consequences if patients seen in specialty or primary care practices did not have ready access to laboratory, other medical tests, and/or consultative services deemed critical to quickly establishing diagnostic status and the development of an appropriate treatment plan. For instance, what would be the implications if a dentistry practice did not employ a dental hygienist; an otolaryngology group was not staffed with an audiologist; or a gastroenterology practice had no one available for digestive/nutritional consultation support.
Consider a neurologist who suspects that a patient has a potentially life-threatening brain condition, but the patient has to wait months for brain imaging or – even worse – is tasked to find their own provider for this diagnostic test only to be told that the neuroimaging service does not take their insurance and/or there are no available appointments for several months.
Situations of this kind would not be – and should not be – tolerated by medical professionals or their patients.
A common “real-world” scenario: After evaluation, a psychiatrist needs clarification regarding a possible subtle psychotic process, or, in another instance, suspects that there is an early degenerative cognitive change underlying recent changes in mood and personality. However, the psychiatrist has no dependable access to an assessment psychologist to assist in cases of this kind.

DNA methylation changes: An early biomarker for methotrexate response?
An investigation into a potential biomarker for response to methotrexate found that changes in DNA methylation at 4 weeks were associated with improvements in rheumatoid arthritis (RA) patients at 6 months.
“The findings in the current study are promising and appear to identify methylation patterns that are predictive of improvement of SJC [swollen joint count] and CRP [C-reactive protein],” wrote Nisha Nair, PhD, of the University of Manchester (England) and her coauthors. The study was published in Rheumatology.
The investigators analyzed DNA samples taken from patients recruited into the Rheumatoid Arthritis Medication Study (RAMS) who had RA or inflammatory polyarthritis and were beginning methotrexate for the first time. The samples were collected at baseline and at 4 weeks from patients who were classified as having good (n = 34) or poor (n = 34) responses to methotrexate after 6 months according to European League Against Rheumatism response criteria, in which good response was defined as having a 28-joint disease activity score (DAS28) of 3.2 or less and a 1.2-point improvement in DAS28 at 6 months, and poor response was defined as having DAS28 higher than 5.1 and improvement of 0.6 points or less at 6 months.
After analysis, two differentially methylated positions that differed between good and poor responders were identified in samples taken at the 4-week mark (P less than 1 × 10–6). Four CpG (cytosine-phosphate-guanine) sites also predicted improvements in RA patients at 6 months: Two sites associated increased methylation in good responders at 4 weeks with long-term SJC improvement, while two others associated increased methylation at baseline and in good responders at 4 weeks with improvement of CRP levels.
The authors acknowledged their study’s limitations, including the fact that the relapsing nature of RA could have contributed to natural variance in DAS28. In addition, the study’s lack of a control group does not allow for separating prognostic from theranostic biomarkers, although they added that “in terms of selecting treatments that will be effective, that may not necessarily matter in the clinical setting.”
The study was funded by the Medical Research Council and Versus Arthritis. The authors reported no conflicts of interest.

Research on pediatric firearms deaths is underfunded
new research has found.
For the period 2008-2017, an average of $88 million per year was granted to study motor vehicle crashes, the leading cause of death in this age group. Cancer, the third leading cause of mortality, received on average $335 million per year. However, research into mortality from firearms, the second leading cause of death in this age group, received $12 million total during the entire research period across a total of 32 research grants.
This translates to $26,136 in research funding per death for the 33,577 deaths of children and adolescents in motor vehicle crashes from 2008-2017, $195,508 per death from cancer (17,111 deaths recorded), and just $597 per death from firearm injury (20,719 deaths recorded).
Pediatric firearm injury prevention “is substantially underfunded in relation to the magnitude of the public health problem,” Rebecca Cunningham, MD, from the University of Michigan, Ann Arbor, and colleagues wrote in the October 2019 issue of Health Affairs.
“According to our analysis, federal funding for this leading cause of pediatric mortality is 3.3 percent of what would be needed for it to be commensurate with the funding for other common causes of pediatric death,” the authors continued.
Dr. Cunningham and colleagues said that the “lack of an evidence base for firearm safety prevention has likely contributed to the lack of progress on, and recent increase in, firearm deaths among children and adolescents since 2013.”
They did note that there was an increase in federal research funding following the shooting in Newtown, Conn., with an increase from $136,224 in 2012 to $4.5 million in 2017, but it clearly is not enough.
“Our analysis, using other major diseases and the country’s history of federal funding as a guide, demonstrates that approximately $37 million per year over the next decade is needed to realize a reduction in pediatric firearm mortality that is comparable to that observed for other pediatric causes of death,” the authors state.
The group also suggests the development of a group similar to the National Highway Traffic Safety Administration that is focused specifically on firearm safety that could “begin to address the large gaps in foundational epidemiological and multidisciplinary behavioral research that the nation needs. It could have a transformational impact on the reduction of firearm injuries among children and adolescents parallel to what has been seen for other major causes of pediatric death in the U.S.”
