Genetic risk score for low vitamin D may affect MS relapse rate
BALTIMORE – A genetic scoring system for identifying individuals at high risk for low vitamin D levels also detected multiple sclerosis patients with an increased risk for relapse in a multicenter cohort study.
The findings could have clinical significance in multiple sclerosis (MS) treatment and patient counseling, Jennifer S. Graves, MD, PhD, of the University of California, San Francisco, said in a brief oral and poster presentation of the study at the annual meeting of the American Neurological Association.
The investigators compared the SNP profile of a discovery cohort of 181 patients with MS or high-risk clinically isolated syndrome (the discovery cohort) who were enrolled at two pediatric MS centers in California between 2006 and 2011 against a replication cohort of 110 patients of comparable age, race, and median vitamin D serum level who were enrolled at nine MS centers elsewhere in the United States from 2011 to 2015.
Three of the SNPs were strongly associated with the vitamin D levels in the discovery cohort after a statistical correction that revealed individual influences of genes among the 29 different mutations. The researchers used these three SNPs to generate risk scores for vitamin D levels. A comparison of the lowest and highest scores revealed a linear association with vitamin D levels. The highest scores were associated with serum vitamin D levels that were nearly 15 ng/mL lower in both the discovery and replication cohorts (P = .00000052 and .002, respectively).
The risk of MS relapse for individuals with the highest risk score in the discovery cohort was nearly twice as high as it was for individuals with the lowest risk score (hazard ratio, 1.94; 95% confidence interval, 1.19-3.15; P = .007).
“A genetic score of three functional SNPs captures risk of low vitamin D level and identifies those who may be at risk of relapse related to this risk factor. These findings support a causal association of vitamin D with relapse rate,” Dr. Graves said.
The study may potentially be important beyond MS. “This risk score may also have some utility in other disease states where vitamin D deficiency may be contributing to disease course,” she said.
The study was funded by The Race to Erase MS, the National Multiple Sclerosis Society, and the National Institute of Neurological Disorders and Stroke. Dr. Graves had no disclosures.

CD64 validated as biomarker for pediatric Crohn’s disease
MONTREAL – Blood levels of a neutrophil receptor protein, CD64, proved to be a reliable, noninvasive marker of both Crohn’s disease activity and the risk for relapse from remission in children and adolescents in a pair of single-center studies with a total of 140 patients.
An elevation in blood levels of CD64, a marker for inflammation, in asymptomatic patients with Crohn’s disease “is a significant risk factor for treatment failure or complications during infliximab maintenance,” Phillip Minar, MD, said at the World Congress of Pediatric Gastroenterology, Hepatology and Nutrition. Although Dr. Minar acknowledged that larger validation studies are still needed, neutrophil CD64 levels can potentially serve as a “treat-to-target” biomarker of disease status in selected pediatric Crohn’s disease patients.
Dr. Minar cautioned that in some pediatric patients with Crohn’s disease CD64 is not an effective marker for inflammation and a change in their Crohn’s disease status. In his study, the sensitivity of an elevated CD64 level was 64% as a surrogate marker for mucosal damage seen with endoscopy.
“I get a CD64 level at the time we diagnose Crohn’s disease. If it is elevated, then I will follow it; if it is not elevated, then I won’t use it for that patient. It’s patient specific,” he explained in an interview.
Dr. Minar and his associates first established the prognostic value of elevated CD64 levels in patients with Crohn’s disease in a study with 208 pediatric patients with inflammatory bowel disease and 43 controls (Inflam Bowel Dis. 2014, Jun;20[6]:1037-48). His new validation study included 105 pediatric patients with Crohn’s disease, of whom 54 were newly diagnosed. Among the 51 previously diagnosed patients, 18 had inactive disease. The patients averaged 14 years old, and all 105 underwent endoscopy to directly examine their Crohn’s disease activity.
The results showed clear and statistically significant correlations among the average CD64 levels in the patients and the blinded endoscopic evaluations that categorized the patients as having inactive Crohn’s disease, mild disease, or moderate to severe disease. The results also suggested that a useful dichotomous cut point for CD64 was an index of 1. Among patients with a level above 1, diagnostic sensitivity for mucosal damage was 64% and specificity was 100%, he reported. In these studies as well as their routine practice, Dr. Minar and his associates use a commercially available immunoassay for quantifying blood levels of CD64.
The second study he reported on assessed the ability of CD64 levels to predict a patient’s status on infliximab (Remicade) maintenance treatment. This study enrolled 35 pediatric patients, who averaged about 15 years old, had been diagnosed with Crohn’s disease for an average of about 2 years and were in remission after having received at least four serial infliximab doses. During 1 year of follow-up, 15 patients relapsed and 21 remained in remission.
The researchers measured CD64 levels at baseline and found that, during the next year, those who had a CD64 index of less than 1 at baseline had a relapse rate of less than 40% during follow-up, while those with a CD64 index of 1 or greater at baseline had a relapse rate of more than 70% during follow-up, a statistically significant difference between the two subgroups. The analysis also showed that lower CD64 levels linked with higher trough levels of infliximab.
A multivariate analysis showed that a CD64 index level of 1 or greater at baseline linked with a statistically significant, 4.5-fold increased risk for relapse, compared with patients with a baseline CD64 level below 1. This analysis identified three additional significant correlates of an elevated risk for relapse: nonwhite race, a baseline serum albumin level of less than 3.9 g/dL, and a baseline infliximab serum level of less than 5 mcg/mL.
The CD64 test that his group has been using typically has a work week turnaround time of about an hour, and costs less than $100 per test per patient. Blood levels of CD64 are stable for 48 hours in the refrigerator, so specimens can sit over a weekend without compromising results. The Cincinnati group is planning to soon change to an in-house test that will cost about $10-$20 per test per patient, Dr. Minar said.
Dr. Minar had no relevant financial disclosures.

We are in desperate need of more reliable biomarkers of disease activity in patients with Crohn’s disease. Identifying effective noninvasive biomarkers has been a holy grail that we have pursued for many years because what we currently have is imperfect. CD64 appears to be a very reliable and specific biomarker of disease activity.
I think pediatric gastroenterologists will pay attention to Dr. Minar’s report. The entire community is very interested in this and will be watching the evolution of the science behind CD64 assessment.

Beta-blockers curb death risk in patients with primary prevention ICD
ROME – Beta-blocker therapy reduces the risks of all-cause mortality as well as cardiac death in patients with a left ventricular ejection fraction below 35% who get an implantable cardioverter-defibrillator for primary prevention, Laurent Fauchier, MD, PhD, reported at the annual congress of the European Society of Cardiology.
Some physicians have recently urged reconsideration of current guidelines recommending routine use of beta-blockers for prevention of cardiovascular events in certain groups of patients with coronary artery disease, including those with chronic heart failure who have received an ICD for primary prevention of sudden death. And indeed it’s true that the now–relatively old randomized trials of ICDs for primary prevention in patients with chronic heart failure don’t provide any real evidence that beta-blockers reduce mortality in this setting. In fact, the guideline recommendation for beta-blockade has been based upon expert opinion. This was the impetus for Dr. Fauchier and coinvestigators to conduct a large retrospective observational study in a contemporary cohort of heart failure patients who received an ICD for primary prevention during a recent 10-year period at the 12 largest centers in France.
Fifteen percent of the 3,975 French ICD recipients did not receive a beta-blocker. They differed from those who did in that they were on average 2 years older, had an absolute 5% lower ejection fraction, and were more likely to also receive cardiac resynchronization therapy. Propensity score matching based on these and 19 other baseline characteristics enabled investigators to assemble a cohort of 541 closely matched patient pairs, explained Dr. Fauchier, professor of cardiology at Francois Rabelais University in Tours, France.
During a mean follow-up of 3.2 years, the risk of all-cause mortality in ICD recipients not on a beta-blocker was 34% higher than in those who were. Moreover, their risk of cardiac death was 50% greater.
In contrast, beta-blocker therapy had no effect on the risks of sudden death or of appropriate or inappropriate shocks.
The finding that beta-blocker therapy doesn’t prevent sudden death in patients with an ICD for primary prevention has not previously been reported. However, it makes sense. The device prevents such events so effectively that a beta-blocker adds nothing further in that regard, according to Dr. Fauchier.
“Beta-blockers should continue to be used widely, as currently recommended, for heart failure in the specific setting of patients with prophylactic ICD implantation. You do not have the benefit for prevention of sudden death, but you still have all the benefit from preventing cardiac death,” the electrophysiologist concluded.
This study was supported by French governmental research grants. Dr. Fauchier reported serving as a consultant to Bayer, Pfizer, Boehringer Ingelheim, Medtronic, and Novartis.

High-risk deliveries much more likely to be C-sections
Cesarean section rates for low-risk deliveries are 4.7 times lower than for deliveries that had a medical indication for the procedure listed in the record, according to the Agency for Healthcare Research and Quality.
The C-section rate for non–low-risk deliveries (deliveries with a medical indication that excluded them from the low-risk category) was 76.1% in 2013, compared with 16.2% for low-risk deliveries. Conversely, 23.9% of non–low-risk deliveries that year were performed vaginally, compared with 83.8% of low-risk deliveries, the AHRQ reported.
The AHRQ analysis combined a new definition of low-risk delivery developed by the Society for Maternal-Fetal Medicine (Am J Obstet Gynecol. 2016;214[2]:153-63) with data from the State Inpatient Databases of 43 states and the District of Columbia. This approach allowed AHRQ researchers to apply the new definition to actual counts of deliveries from 2,719 hospitals – representing 95% of the population – instead of national estimates based on a much smaller sample.

Conversely, 23.9% of non–low-risk deliveries that year were performed vaginally, compared with 83.8% of low-risk deliveries, the AHRQ reported.
The AHRQ analysis combined a new definition of low-risk delivery developed by the Society for Maternal-Fetal Medicine (Am J Obstet Gynecol. 2016;214[2]:153-63) with data from the State Inpatient Databases of 43 states and the District of Columbia. This approach allowed AHRQ researchers to apply the new definition to actual counts of deliveries from 2,719 hospitals – representing 95% of the population – instead of national estimates based on a much smaller sample.
Health care workers at risk for mild MERS-CoV infections
Health care workers directly caring for patients with Middle East respiratory syndrome coronavirus (MERS-CoV) are more highly predisposed to contracting the virus, but in a milder form than that of their patients, thus making it difficult to diagnose and treat.
In a study published in Emerging Infectious Diseases, health care professionals (HCP) from the King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, were examined to determine their likelihood for getting MERS-CoV based on their proximity to patients who already had it. 
“Healthcare settings are important amplifiers of transmission,” explained the investigators, led by Basem M. Alraddadi, MD. “Current MERS-CoV infection control recommendations are based on experience with other viruses rather than on a complete understanding of the epidemiology of MERS-CoV transmission.”
Dr. Alraddadi and his coinvestigators identified 363 HCP, all of whom would be placed into one of three cohorts based on the department in which they worked most extensively: the Medical Intensive Care Unit (MICU), the emergency department (ED), and the neurology unit. A total of 292 HCP were ultimately enrolled in the study: 131 in MICU, 127 in ED, and 34 in neurology. After 9 subjects were excluded because of unavailability of serum specimens, 128 MICU, 122 ED, and 33 neurology unit workers remained.
While none of the neurology unit workers contracted the virus, 15 MICU workers (11.7%) and 5 ED workers (4.1%) did, for a total of 20 out of the 250 subjects in those two cohorts (8%). Radiology technicians were the most susceptible, as 5 of 17 (29.4%) got the virus, followed by 13 of 138 nurses (9.4%), 1 of 31 respiratory therapists (3.2%), and 1 of 41 physicians (2.4%).
“HCP who reported always covering their nose and mouth with either a medical mask or N95 respirator had lower risk for infection than did HCP reporting not always or never doing so, [while] those who reported always using N95 respirators for direct patient contact were less likely to be seropositive, a trend that approached statistical significance (P = .07),” the authors noted.
The most frequent symptoms reported by those surveyed were muscle pain, fevers, headaches, dry cough, and shortness of breath. In the 20-case HCP sample, however, 12 subjects (60%) only had mild illness while 3 (15%) were asymptomatic, making it very hard to diagnose and treat their infection. Three subjects (15%) had severe illness, while another two (10%) had moderate illness, meaning they were admitted to hospital but did not require any mechanical ventilation.
“Our study did not identify strong associations with underlying chronic illnesses, most likely because the prevalence of such conditions was low ([less than] 10%) in this population, [but] HCPs with a history of smoking had a risk for infection almost 3 times that of nonsmokers,” the authors wrote (Emerg Infect Dis. 2016 Nov. doi: 10.3201/eid2211.160920).
The Ministry of Health of Saudi Arabia and the Centers for Disease Control and Prevention funded the study. Dr. Alraddadi and his coauthors did not report any disclosures.

FALCON airs PFS edge for fulvestrant in ER+ breast cancer
COPENHAGEN – Fulvestrant continues to show superiority over anastrozole in treatment of hormone receptor-positive breast cancer, particularly in women with lower-volume disease, reported investigators in the phase III FALCON trial.
At a median follow-up of 25 months, median progression-free survival (PFS) for women assigned to receive the selective estrogen-receptor degrader fulvestrant (Faslodex) was 16.6 months, compared with 13.8 months for women assigned to receive the aromatase inhibitor anastrozole (Arimidex), reported Matthew J. Ellis, PhD, of the Lester and Sue Smith Breast Center at Baylor College of Medicine in Houston.
“These results are consistent with data from the FIRST study and confirm that fulvestrant is more efficacious than anastrozole in postmenopausal women with hormone receptor–positive locally advanced or metastatic breast cancer who have not received prior endocrine therapy,” he said at the European Society for Medical Oncology Congress.
The benefit of fulvestrant appeared to be only among patients who did not have visceral metastases, however.
In the FIRST study, results of which were reported at the San Antonio Breast Cancer Symposium in 2014, median overall survival at a median follow-up of 48.8 months was 54.1 months in patients on fulvestrant, vs. 48.4 months with anastrozole (hazard ratio [HR] 0.70, P = .04). The median PFS durations were 23.4 months vs. 13.1 months, respectively (HR 0.66, P = .01).
The FALCON (Fulvestrant and Anastrozole Compared in Hormonal Therapy-Naive Advanced Breast Cancer) trial was a phase III study designed to confirm the PFS benefit seen with fulvestrant in the earlier trial.
Postmenopausal women with locally advanced or metastatic breast cancer positive for the estrogen and/or progesterone receptor and negative for HER2 who had not previously received endocrine therapy were enrolled. They were randomly assigned to receive fulvestrant 500 mg intramuscularly on days 0, 14, and 28 then every 28 days plus an anastrozole placebo (232 patients), or oral anastrozole 1 mg daily plus fulvestrant placebo (230 patients).
Women with life-threatening visceral metastases, systemic estrogen-containing hormone replacement therapy within 6 months of randomization, or prior systemic treatment for breast cancer other than one line of chemotherapy or radiotherapy within 28 days of randomization (except radiation for control of bone pain) were excluded.
As noted, the primary endpoint of PFS was 16.6 months in the fulvestrant arm vs. 13.8 months in the anastrozole arm, translating into an HR for progression on fulvestrant of 0.797 (P = .0486).
Among the 208 patients with no visceral disease, median PFS with fulvestrant was 22.3 months, vs. 13.8 months (HR 0.59, P less than .01). In contrast, among the 254 patients with visceral disease, the respective median PFS durations were 13.8 and 15.9 months (nonsignificant).
For the secondary endpoint of overall survival, at 31% maturity (longest follow-up out to 39 months), there was no significant difference between the study arms.
There were also no significant differences in the secondary endpoints of overall response rate (among patients with measurable disease at baseline), clinical benefit rate, median duration of response, median duration of clinical benefit, or median time to deterioration of total score on the Functional Assessment of Cancer Therapy–Breast (FACT-B) patient-reported outcomes instrument.
Only estimated duration of response (11.4 vs. 7.5 months) and estimated duration of clinical benefit (21.9 vs. 17.5 months) were significantly better with fulvestrant (P less than .001 for each).
Grade 3 or greater adverse events occurred in 22.4% vs. 17.7%. Deaths from adverse events occurred in six patients on fulvestrant vs. seven on anastrozole. None of these deaths were considered to be related.
The FALCON results, which showed a benefit for fulvestrant only for those patients without visceral disease, point to a need for investigating whether patients with visceral metastases should receive other therapies, but this observation is hypothesis-generating only, said invited discussant Peter Schmid, MD, PhD, of Barts Cancer Institute at St. Bartholomew’s Hospital at Queen Mary University of London.

Missed Adult Vaccines Cost U.S. Nearly $9 Billion in 2015
Just how important are adult vaccines? According to a new study from Health Affairs missed vaccines cost the U.S. economy $8.95 billion in 2015. “This review not only estimated the direct costs and productivity losses due to inpatient and outpatient visits associated with vaccine-preventable diseases…but [it also] examined this across all vaccines recommended for US adults,” authors Sachiko Ozawa, Allison Portnoy, Hiwote Getaneh, Samantha Clark, Maria Knoll, David Bishai, H. Keri Yang, and Pallavi D. Patwardhan explained.
“Low rates of vaccine uptake lead to costs to individuals and society in terms of deaths and disabilities, which are avoidable, and they create economic losses from doctor visits, hospitalizations, and lost income,” the authors argued. “To identify the magnitude of this problem, we calculated the current economic burden that is attributable to vaccine-preventable diseases among US adults.
Not surprisingly, preventable influenza exacted the highest cost, estimated to be $5.8 billion. Pneumococcal disease was second, with an estimated cost of $1.9 billion, followed by herpes zoster ($782 million), human papillomavirus, and hepatitis B ($173 million).
Researchers were from University of North Carolina at Chapel Hill, Harvard T. H. Chan School of Public Health, in Boston, Massachusetts, MRDC in New York City, Johns Hopkins Bloomberg School of Public Health, in Baltimore, Maryland, and Merck. This study was funded by Merck. The study “highlights the need for US adults to better appreciate the value of vaccines to prevent economic burden,” they said.

Earlier ischemic stroke presentation may sometimes mean delayed tPA
BALTIMORE – Going to the hospital soon after the development of symptoms of acute ischemic stroke may not guarantee quick treatment.
A study of 1,865 patients treated within the past decade at a large urban comprehensive stroke center has revealed delayed treatment with tissue plasminogen activator, compared with patients who came to the emergency room hours after symptom development, Dr. Kyle C. Rossi said at the annual meeting of the American Neurological Association.
Treatment with tissue plasminogen activator (tPA) within 3 hours after the first symptoms of acute ischemic stroke definitely improves long-term outcomes, but meeting this target time remains a challenge. Patients who present to the emergency room soon after symptom development would seemingly have an advantage, yet Dr. Rossi’s preliminary scrutiny of patient records at Mount Sinai raised doubts about this and prompted the present study.
The hypothesis was that cases with a shorter time between symptom development and diagnosis of stroke (last known well-to-stroke code time, or LKW-to-code) will have a longer time between diagnosis and tPA administration (code-to-tPA), “possibly due to the perception on the part of evaluating physicians of sufficient remaining time before the end of the tPA window.”
The researchers examined patient records from the American Heart Association/American Stroke Association’s “Get with the Guidelines” stroke program, a voluntary observational registry for patients with acute stroke. Of the 1,865 ischemic stroke patients treated during 2009-2015, 122 who received intravenous tPA were allocated to three LKW-to-code groups: within an hour (38 patients), within the next hour (49 patients), or 2 hours or more (35 patients).
The patients tended to be in their late 60s. Just over half were female, and about 40% were white.
Overall, the average LKW-to-code time was 91 ± 48 minutes and the average code-to-tPA time was 67 ± 26 minutes.
Average code-to-tPA times were 80, 67, and 52 minutes, respectively, for the three groups (P less than .0001). On average, it took 28 minutes longer to give tPA to patients who presented within an hour than to patients presenting 2 hours or longer after their first stroke symptom. There was an increase in code-to-tPA time of 1 minute for every decrease in LKW-to-code time of 4 minutes (P less than .0001).
The delay in the time to treat patients who arrive sooner after development of stroke symptoms may result from a decision made by the evaluating neurologist to conduct additional testing prior to administering tPA. Sometimes other staff may be unaware of the decision to delay treatment, according to Dr. Rossi and his colleagues.
“Absolutely, folks coming in soon after symptoms develop should be treated early. But treatment needs to balance rapid delivery with adequate testing. Sometimes, when there is some time to spare before the optimum treatment window closes we can do a more thorough examination and address lingering questions,” Dr. Rossi said.
The decision to get more information about the patient’s condition reflects the goal to give tPA as soon as safely possible to the right patients. While laudable, the study highlights that the timing of treatment can be improved.
Dr. Rossi reported having no financial disclosures.

The patients tended to be in their late 60s. Just over half were female, and about 40% were white.
Overall, the average LKW-to-code time was 91 ± 48 minutes and the average code-to-tPA time was 67 ± 26 minutes.
Average code-to-tPA times were 80, 67, and 52 minutes, respectively, for the three groups (P less than .0001). On average, it took 28 minutes longer to give tPA to patients who presented within an hour than to patients presenting 2 hours or longer after their first stroke symptom. There was an increase in code-to-tPA time of 1 minute for every decrease in LKW-to-code time of 4 minutes (P less than .0001).
The delay in the time to treat patients who arrive sooner after development of stroke symptoms may result from a decision made by the evaluating neurologist to conduct additional testing prior to administering tPA. Sometimes other staff may be unaware of the decision to delay treatment, according to Dr. Rossi and his colleagues.
“Absolutely, folks coming in soon after symptoms develop should be treated early. But treatment needs to balance rapid delivery with adequate testing. Sometimes, when there is some time to spare before the optimum treatment window closes we can do a more thorough examination and address lingering questions,” Dr. Rossi said.
The decision to get more information about the patient’s condition reflects the goal to give tPA as soon as safely possible to the right patients. While laudable, the study highlights that the timing of treatment can be improved.

BALTIMORE – Going to the hospital soon after the development of symptoms of acute ischemic stroke may not guarantee quick treatment.
A study of 1,865 patients treated within the past decade at a large urban comprehensive stroke center has revealed delayed treatment with tissue plasminogen activator, compared with patients who came to the emergency room hours after symptom development, Dr. Kyle C. Rossi said at the annual meeting of the American Neurological Association.
Treatment with tissue plasminogen activator (tPA) within 3 hours after the first symptoms of acute ischemic stroke definitely improves long-term outcomes, but meeting this target time remains a challenge. Patients who present to the emergency room soon after symptom development would seemingly have an advantage, yet Dr. Rossi’s preliminary scrutiny of patient records at Mount Sinai raised doubts about this and prompted the present study.
The hypothesis was that cases with a shorter time between symptom development and diagnosis of stroke (last known well-to-stroke code time, or LKW-to-code) will have a longer time between diagnosis and tPA administration (code-to-tPA), “possibly due to the perception on the part of evaluating physicians of sufficient remaining time before the end of the tPA window.”

Novel Messenger RNA Vaccine in Development for Zika
A novel anti-Zika vaccine based on messenger RNA (mRNA) technology received financial backing from HHS. Moderna Therapeutics, Cambridge, Massachusetts, will get $8.2 million to accelerate the development of the vaccine.
Messenger RNA carries specific genetic codes to parts of the cell. The vaccine uses mRNA containing the genetic sequence of the Zika virus to generate an immune response.
This technology produces vaccine faster than other methods, which require the growth and purification of an attenuated or inactivated virus, HHS says. Moderna also is designing the vaccine to be easy to administer by not requiring any specialized delivery devices.
Under the initial 4-year agreement, HHS’ Biomedical Advanced Research and Development Authority (BARDA) will support a phase 1 clinical trial, toxicology studies, vaccine formulation, and manufacturing. If additional funding is identified the agreement could be extended to 5 years, with a total of $125.5 million to cover phase 2 and 3 clinical trials and large-scale manufacturing.
The funding is part of an obligated $85 million BARDA “reprogrammed” for Zika work. The funds are also being used to develop other Zika vaccines, blood screening tests, and pathogen reduction technologies.
