STOWE, VT. – “The eye is intimately involved in the migraine process,” said Kathleen Digre, MD, at the annual meeting of the Headache Cooperative of New England. Specifically, she said, dry eye and photophobia are two symptoms that have biologic underpinnings, can be diagnosed, and can be treated. Dr. Digre is a professor of neurology and ophthalmology at the University of Utah, Salt Lake City, and is the current president of the American Headache Society.

Dr. Digre explained that dry eyes and migraine could have a cyclical relationship where dry eyes provoke the migraine, and the migraine may provoke the feeling of dry eye, regardless of whether it can be objectively measured.

Regarding photophobia, Dr. Digre stressed the importance of an accurate diagnosis that rules out eye disorders and other causes of photophobia. She discussed the problem of patient overreliance on dark glasses and encourages a return to light to break the cycle of dark adapting the retina.

Finally, Dr. Digre discussed how proper treatment of migraine and any associated anxiety or depression can help resolve eye issues that may be contributing to migraine.

STOWE, VT. – These are the early days of the “CGRP monoclonal antibody era,” Peter McAllister, MD, said in a summary of the current status of calcitonin gene-related peptide monoclonal antibodies for migraine prevention. He discussed what has been learned in the clinical trials of these drugs as well as in the first 10 months of having them on the market.

In an interview at the annual meeting of the Headache Cooperative of New England, Dr. McAllister said, “We are comforted that we have now 1-year, 3-year, and 5-year data” from clinical trials, but the sample size is small.

In the time since the first three drugs were approved, “we have probably in the ballpark of over 200,000 patients who have received a monoclonal antibody, and so far there has been nothing that makes us stop cold in our tracks and say there’s something wrong here. That is very comforting,” he said. Dr. McAllister is the medical director of the New England Institute for Neurology and Headache in Stamford, Conn.

What is still unknown, however, is the long-term safety and efficacy; what happens in a larger pool of patients taking these drugs; what happens in pregnancy and effects on the fetus; how and when to safely switch from one monoclonal antibody to another; the systemic effects of these drugs; and other concerns that may arise in postmarketing studies.

DALLAS – Systemic lupus erythematosus, depression, hyperthyroidism, and anxiety are among the comorbidities that most affect health-related quality of life in patients with multiple sclerosis (MS), according to an analysis presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. In addition, comorbidities account for about 18% of the variance in health-related quality of life, and a higher number of comorbidities correlates with lower health-related quality of life in a “clear dose–response” manner, the researchers said.

The “magnitude of effect emphasizes the need for recognition and appropriate management of comorbidities,” said presenting author Lara Marie Pangan Lo, a researcher at Menzies Institute for Medical Research at the University of Tasmania, Australia, and her research colleagues. “The individual effect sizes may assist with the prioritizing of comorbidities that require more or less aggressive treatment in order to minimize” their impact.

Prior studies have found that patients with MS have lower health-related quality of life, compared with the general population, and that comorbidities affect patients’ quality of life, but few studies have looked at the effects of individual comorbidities on quality of life, Ms. Lo and her colleagues said. To examine the total impact and relative importance of comorbidities on psychosocial, physical, and overall health-related quality of life in people with MS, the investigators analyzed survey data from 902 participants in the survey-based Australian MS Longitudinal Study. They used linear regression and dominance analysis to assess relationships between comorbidities and participants’ Assessment of Quality of Life-8 Dimensions scores, which can range from 0 (death) to 1 (perfect health).

The predicted health-related quality of life for patients without comorbidities was 0.74. After the researchers adjusted for age, sex, and education, they found that systemic lupus erythematosus (reported by 1.56% of patients), depression (41.25%), hyperthyroidism (3.01%), and anxiety (38.35%) were associated with the greatest estimated decreases in health-related quality of life (–0.16, –0.15, –0.12, and –0.11, respectively). Depression and anxiety had the largest effect on psychosocial health–related quality of life, whereas systemic lupus erythematosus, rheumatoid arthritis, and hyperthyroidism had the largest impact on physical health–related quality of life. Other comorbidities that significantly correlated with quality of life included osteoporosis, type 2 diabetes, migraine, and inflammatory bowel disease.

HONOLULU – During the first month after a new cancer diagnosis, patients face a substantially elevated risk for an arterial thromboembolic event – an MI or stroke – consistent with the well-described increased risk newly diagnosed cancer patients face from venous thromboembolism, based on findings from a prospective study of more than 4,000 people.

In the new study, 836 patients newly diagnosed with cancer had a 480% increased rate of a fatal or nonfatal MI or stroke during the 30 days following their diagnosis, compared with 3,339 matched people without cancer and after adjustment for baseline differences in demographics and cardiovascular risk factors, Babak B. Navi, MD, said while presenting a poster at the International Stroke Conference sponsored by the American Heart Association.

An additional analysis that focused on 210 of the 836 patients with incident cancer who had any of seven of the cancers known to pose the highest venous thromboembolism risk (lymphoma; gynecologic cancer; or cancer of the pancreas, stomach, lung, bladder, or testes) showed an 1,750% greater rate of incident MI or stroke during the first 30 days after diagnosis, compared with matched people without cancer, reported Dr. Navi, chief of the stroke and hospital neurology at Weill Cornell Medicine, New York.

In contrast, during both the period 1-3 months after the cancer diagnosis and more than 3 months after, the rate of MI or stroke among recently diagnosed cancer patients was not significantly different from the rate in comparator individuals, although the data showed modest trends toward more arterial thromboembolic events after a month, and the lack of statistically significant differences may have been a power issue, Dr. Navi suggested.

Dr. Navi and his associates designed this study to validate previously reported findings of increased arterial thromboembolic events in newly diagnosed cancer patients from studies of insurance claims databases. Although the increased risk for venous thromboembolism in cancer patients is already well established, documenting a similar risk for arterial events is important because they are “generally more impactful for patients than venous thromboembolism,” Dr. Navi said.

HONOLULU – Acute ischemic stroke patients who underwent endovascular thrombectomy and then had a peak systolic blood pressure of greater than 158 mm Hg during the next 24 hours had worse 90-day outcomes than did patients whose peak systolic pressure remained at or below 158 mm Hg in a prospective, multicenter, observational study with 485 patients.

Mitchel L. Zoler/MDedge News

The results hint that maintaining a lower systolic blood pressure after thrombectomy in acute ischemic stroke patients may improve outcomes, but because the current study was observational, the hypothesis that patients benefit when treatment keeps their systolic pressure at or below 158 mm Hg must undergo testing in a prospective, randomized trial, Eva A. Mistry, MBBS, said at the International Stroke Conference, sponsored by the American Heart Association.

The finding from this study that 158 mm Hg provided the best dichotomous division between systolic blood pressures linked with good or bad outcomes is a first step toward trying to devise a more systematic and evidence-based approach to blood pressure management in acute ischemic stroke patients following endovascular thrombectomy, said Dr. Mistry, a neurologist at Vanderbilt University in Nashville, Tenn.

Neither Vanderbilt nor any of the other 11 major U.S. stroke centers that participated in the current study currently have an established protocol for blood pressure management after thrombectomy, Dr. Mistry said in an interview.

“We usually treat to reduce blood pressure, but we don’t have a [broadly agreed on] threshold” to trigger treatment. “It depends on a collective decision” by the various medical specialists who care for an individual acute stroke patient. In addition, no consensus yet exists for the best treatment strategy for blood pressure lowering in acute ischemic stroke patients. Intravenous nicardipine is often the top choice because it is fast-acting and easy to administer and control as an intravenous agent. Those same properties make the beta blocker labetalol a frequently used second drug, she said.

The BEST (Blood Pressure After Endovascular Stroke Therapy) study ran at 12 U.S. centers and enrolled 485 patients who underwent endovascular thrombectomy to treat an acute ischemic stroke. The patients averaged 69 years old, and 48% also underwent thrombolytic treatment. The study’s primary outcome was the percentage of patients with a modified Rankin Scale score of 0-2 at 90 days after their stroke, an outcome reached by 39% of all patients in the study.

Statistical analysis of the collected data showed that a peak systolic blood pressure of 158 mm Hg reached during the 24 hours following thrombectomy best divided patients with good 90-day outcomes from those with worse outcomes. Patients with a postthrombectomy peak systolic pressure above 158 mm Hg had a 2.2-fold increased rate of having a modified Rankin Scale score of 3 or higher after 90 days, a statistically significant relationship, Dr. Mistry reported. However, in an analysis that also adjusted for age, baseline stroke severity, glucose level, time to reperfusion, ASPECTS score, history of hypertension, and recanalization status, the elevated risk for a bad outcome linked with higher systolic pressure dropped to 39% greater than that for patients with systolic pressures that did not rise above 158 mm Hg, a difference that was not statistically significant. This suggests that these adjustments were unable to account for all confounders and further highlighted the need for a prospective, randomized trial to test the value of controlling blood pressure following thrombectomy, Dr. Mistry said. The unadjusted results confirmed a prior report from Dr. Mistry and her associates that found a link between higher blood pressure after stroke thrombectomy and worse outcomes (J Am Heart Assoc. 2017 May 18. doi: 10.1161/JAHA.117.006167).

The analysis also showed that patients who were successfully recanalized by thrombectomy, achieving a thrombolysis in cerebral infarction (TICI) score of 2b or 3, had lower peak systolic blood pressures than did patients who failed to get this level of restored cerebral blood flow from thrombectomy.

“We want our patients to feel comfortable when they come to us in their 20s or 30s and they get diagnosed, they’re scared, and it’s all new to them,” one of the study authors, Casey E. Engel said in an interview at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. “We want them to know that family planning is something to consider and that they can proceed with having a family with our help and guidance.”

In an effort to collect patient-experience data around family planning, pregnancy, and breastfeeding post-MS diagnosis, Ms. Engel and senior author Myla D. Goldman, MD, mailed a survey to 1,000 women with confirmed MS diagnosis who had received care at the University of Virginia Medical Center in Charlottesville. The researchers reported findings from 173 respondents, of whom 70% were receiving specialty care for MS. Most of the survey participants (137) did not become pregnant following their diagnosis, while 36 did.

Of the 137 respondents who did not become pregnant following diagnosis, 22 (16%) indicated that their decision was driven by MS-related concerns, including MS worsening with pregnancy (64%), ability to care for child secondary to MS (46%), lack of knowledge about options for pregnancy and MS (18%), passing MS onto child (18%), and stopping disease-modifying therapy (DMT) to attempt pregnancy (9%).

Of the 36 women who had a pregnancy following diagnosis, 20% reported postpartum depression or anxiety, higher than the national average of 10%-15%. In addition, 79% reported not being on DMT at the time of conception, 9% were on either glatiramer acetate injection or interferon beta-1a at time of conception, and 3% were on fingolimod (Gilenya) at time of conception. The majority reported receiving inconsistent advice about when to discontinue DMT before attempting pregnancy (a range from 0 to 6 months).

“It’s also noteworthy that 20% took a year to achieve pregnancy,” said Dr. Goldman, a neurologist who directs the university’s MS clinic. “If these women stop [their DMT] 6 months in advance and they take a year to achieve pregnancy, that’s 18 months without therapeutic coverage. That’s a concern to bring to light.”

Breastfeeding was reported in 71% of mothers in postdiagnosis pregnancy with a range between 1 week and 10 months, driven in part by variable guidelines regarding DMT reinitiation. In the meantime, respondents who did not breastfeed made this decision due to fear of relapse, glucocorticoids, or desire to reinitiate medication.

“Though our study was limited by low survey response, we hope that our work may highlight the difficulty our patients face and foster discussions within the MS community around these issues to improve the individual patient experience,” the researchers wrote in their poster.

Ms. Engel worked on the study while an undergraduate at the University of Virginia. The study was supported by the ziMS Foundation.

DALLAS – Low or undetectable levels of teriflunomide (Aubagio) occur in women who are sexually active with men taking the drug for relapsing multiple sclerosis, results from a small study demonstrated.

Doug Brunk/MDedge News

“One of the issues with this particular drug is that it carries a strong pregnancy warning because in animal studies the drug has been teratogenic,” Joseph B. Guarnaccia, MD, said in an interview at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. “The other issue is that it remains detectable in the body for some time. The issue of females taking this drug and conception are well known. There are strong warnings that, if a woman wants to become pregnant, the drug should be removed quickly from the system. But if their male partner is on the drug, does that pose a risk to their female partner? That question has never been addressed in a human study.”

The Food and Drug Administration prescribing information recommends that men wishing to father a child should discontinue use of teriflunomide and undergo the accelerated elimination procedure. It also recommends that female partners wishing to become pregnant should discontinue the drug and undergo an accelerated elimination procedure to verify that the plasma teriflunomide concentration is less than 0.020 mcg/mL.

In an effort to test the risk of female exposure to potentially teratogenic levels of teriflunomide through sexual intercourse, Dr. Guarnaccia, a neurologist with the Multiple Sclerosis Treatment Center at Griffin Hospital in Derby, Conn., and his colleagues recruited 10 couples and compared serum levels of teriflunomide in men with relapsing multiple sclerosis with those of their female partners. Enrollment criteria for men included a diagnosis of relapsing multiple sclerosis, age between 18 and 55 years, treatment with teriflunomide for at least 2 months prior to study entry, and frequency of sexual intercourse with their female partners at least twice a month. Pregnancy was excluded in females, and couples could not use barrier or withdrawal methods of contraception. The couples completed a brief questionnaire and underwent a one-time blood draw for teriflunomide levels either at the investigator’s office or at a LabCorp facility.

The mean age of study participants was 47 years and the mean frequency of intercourse was seven episodes per month. The mean teriflunomide concentration in men was 42.30 mcg/mL (ranged from 10.07 to 142.84 mcg/mL). Six women had teriflunomide below detection levels (0.020 mcg/mL). However, four women had detectable levels that averaged 0.045 mcg/mL (ranging from 0.022 to 0.077 mcg/mL).

“This small study demonstrates that low or undetectable levels of teriflunomide occur in females who are sexually active with males taking teriflunomide for relapsing multiple sclerosis,” the researchers wrote in their poster. They found that women who had low detectable levels of teriflunomide, compared with women with undetectable levels, did not engage in more frequent sexual intercourse nor were their levels associated with higher levels of teriflunomide in their male partners.

“Indeed, one might have expected a positive correlation between serum levels of teriflunomide in females and the frequency or concentration of inoculation in semen from their partners,” the researchers wrote. “While semen levels of teriflunomide were not measured in this study, it might be assumed that serum and semen concentrations of small molecules like teriflunomide are similar.”

The study was supported by a investigator-sponsored research grant from Sanofi-Genzyme. Dr. Guarnaccia reported that he has received speaking honoraria and educational grants from Sanofi-Genzyme, Biogen, Teva, Acorda Therapeutics, Bayer, EMD Serono, and Genentech.

Clinical trials represent future hope for patients seeking better care, and there is no disease more in need of better care than Alzheimer’s disease. While death rates among most cancers, as well as heart disease, HIV-related illness, and other categories, have declined in the past decade, there has been no progress for Alzheimer’s disease. Better health and wellness overall may be having a beneficial effect that has produced a reduction in age-adjusted dementia rates, but with the aging of the population there are a greater absolute number of dementia cases than ever before, and that number is expected to continue rising. Finding a disease-modifying therapy seems to be the best hope for changing this dim outlook. Clinical trials intend to do just that but are hampered by patient enrollment rates that remain low. Far fewer eligible patients enroll than are needed, causing studies to take longer to complete, driving up their costs and essentially slowing progress. There is a need to increase patient enrollment, and there has been a variety of efforts intended to address this, not the least of which has been an explosion of media coverage of Alzheimer’s disease.

The Global Alzheimer’s Platform (GAP) Foundation, a nonprofit, self-described patient-centric entity dedicated to reducing the time and cost of Alzheimer’s disease clinical trials, recently announced an initiative to increase participation in Alzheimer’s clinical trials by supporting and collaborating with “memory fitness programs” through select Medicare Advantage plans. At worst, this seems a harmless way to increase attention and hopefully interest in clinical trial participation. At best, this may be a cost-effective way to increase enrollment and even improve dementia care. Dementia is notoriously underdiagnosed, especially by overworked, busy primary care providers who simply lack the time to perform the time-consuming testing that is typically required to diagnose and follow such patients.

There are some caveats to consider. First, memory fitness programs are of dubious benefit. They generally fit the description of being harmless, but there is little compelling evidence that they preserve or improve memory.

Second, enrollment in a clinical trial, for a patient, is not always a winning proposition. To date, there has been little success and in the absence of benefit, any downside – even if simply an inconvenience – is a net negative. Recently at the 2018 Clinical Trials on Alzheimer’s Disease meeting, Merck reported that patients with mild cognitive impairment receiving active treatment in the BACE1 inhibitor verubecestat trial actually declined at a more rapid rate than did those on placebo. While the absolute difference was small, and one could argue whether it was clinically significant or simply a random occurrence, it was a reminder that intervention with an experimental agent is not necessarily benign.

Third, Medicare Advantage plans, while popular in some circles, are not considered advantageous to providers so that the proliferation of inadequate reimbursement will potentially fuel the accelerating number of providers who opt out of insurance plans altogether. This is not necessarily an issue for the GAP Foundation specifically but is nonetheless an issue for anything that promotes MA plans).

Finally, it remains important to help patients and families maintain a positive outlook, especially when we have nothing better to offer. Alzheimer’s disease is not a death sentence for every patient affected. While many have difficult and heartbreaking courses, some have slowly progressive courses with relatively little impairment for an extended period of time. There are also the dementia-phobic, cognitively unimpaired individuals (or who simply have normal age-associated cognitive changes) in whom the continued drumbeat of dementia awareness and memory testing raises their paranoia ever higher. We treat deficits (or try to), but we have to live based on our preserved skills. The challenge clinicians must face with patients and families is how to maximize function while compensating for deficits and making sure that patients and families maintain their hope.

A recently developed blood-based signature can help predict the status of an early Alzheimer’s disease risk indicator with high accuracy, investigators are reporting.

By analyzing as few as four proteins, the machine learning-derived test can predict the status of cerebrospinal fluid (CSF) amyloid beta_1-42 (Abeta1-42), according to Noel G. Faux, PHD, of IBM Australia and the University of Melbourne, and co-investigators.

While shifts in Abeta1-42 may signal the presence of disease long before significant cognitive decline is clinically apparent, collection of CSF is highly invasive and expensive, Faux and investigators said in their report.

By contrast, blood biomarkers could prove to be a useful alternative not only to invasive lumbar punctures, they said, but also to the positron emission tomography (PET) evaluation of Abeta1-42, which is expensive and limited in some regions.

“In conjunction with biomarkers for neocortical amyloid burden, the CSF Abeta1-42biomarkers presented in this work may help yield a cheap, non-invasive tool for both improving clinical trials targeting amyloid and population screening,” Dr. Faux and co-authors said in Scientific Reports.

Dr. Faux and colleagues used a Random Forest approach to build models for CSF Abeta1-42 using blood biomarkers and other variables.

They found that a model incorporating age, APOEe4 carrier status, and a number of plasma protein levels predicted Abeta1-42 normal/abnormalstatus with an AUC, sensitivity and specificity of 0.84, 0.78 and 0.73 respectively.

In a model they said was more suitable for clinical application, they narrowed down the variables to 4 plasma analytes and APOEe4 carrier status, which had an AUC, sensitivity, and specificity of 0.81, 0.81 and 0.64 respectively.

They validated the models on a cohort of individuals in the Alzheimer’s Disease Neuroimaging Initiative (ADNI), a large, longitudinal, multicenter study.

Patients with mild cognitive impairment with predicted abnormal CSF Abeta1-42 levels indeed did transition to a diagnosis of Alzheimer’s disease more quickly than those with predicted normal levels, according to investigators.

That helps provide “strong evidence” that the blood-based model is generalizable, robust, and could help stratify patients based on risk of progressing to Alzheimer’s disease, they said in their report.

Dr. Faux and colleagues declared no conflicts of interest related to the research.

By analyzing as few as four proteins, the machine learning-derived test can predict the status of cerebrospinal fluid (CSF) amyloid beta_1-42 (Abeta1-42), according to Noel G. Faux, PHD, of IBM Australia and the University of Melbourne, and co-investigators.

While shifts in Abeta1-42 may signal the presence of disease long before significant cognitive decline is clinically apparent, collection of CSF is highly invasive and expensive, Faux and investigators said in their report.

By contrast, blood biomarkers could prove to be a useful alternative not only to invasive lumbar punctures, they said, but also to the positron emission tomography (PET) evaluation of Abeta1-42, which is expensive and limited in some regions.

“In conjunction with biomarkers for neocortical amyloid burden, the CSF Abeta1-42biomarkers presented in this work may help yield a cheap, non-invasive tool for both improving clinical trials targeting amyloid and population screening,” Dr. Faux and co-authors said in Scientific Reports.

Dr. Faux and colleagues used a Random Forest approach to build models for CSF Abeta1-42 using blood biomarkers and other variables.

They found that a model incorporating age, APOEe4 carrier status, and a number of plasma protein levels predicted Abeta1-42 normal/abnormalstatus with an AUC, sensitivity and specificity of 0.84, 0.78 and 0.73 respectively.

In a model they said was more suitable for clinical application, they narrowed down the variables to 4 plasma analytes and APOEe4 carrier status, which had an AUC, sensitivity, and specificity of 0.81, 0.81 and 0.64 respectively.

They validated the models on a cohort of individuals in the Alzheimer’s Disease Neuroimaging Initiative (ADNI), a large, longitudinal, multicenter study.

Patients with mild cognitive impairment with predicted abnormal CSF Abeta1-42 levels indeed did transition to a diagnosis of Alzheimer’s disease more quickly than those with predicted normal levels, according to investigators.

That helps provide “strong evidence” that the blood-based model is generalizable, robust, and could help stratify patients based on risk of progressing to Alzheimer’s disease, they said in their report.

Dr. Faux and colleagues declared no conflicts of interest related to the research.

DALLAS – Of 95 patients referred to two multiple sclerosis (MS) centers for a possible diagnosis of MS, 74% did not have MS, according to a study presented at ACTRIMS Forum 2019. A majority had clinical syndromes or imaging findings that are atypical for MS, which “underscores the importance of familiarity with typical MS clinical and imaging findings in avoiding misdiagnosis,” said Marwa Kaisey, MD, and her research colleagues. Dr. Kaisey is a neurologist at Cedars-Sinai Medical Center in Los Angeles.

Physicians often refer patients to academic MS centers to determine whether patients have MS or one of its many mimics. To study the characteristics and final diagnoses of patients referred to MS centers for evaluation of possible MS, the investigators reviewed electronic medical records and MRI from all new patient evaluations at the Cedars-Sinai Medical Center and University of California, Los Angeles MS clinics between July 2016 and June 2017. The researchers excluded patients referred with a previously established diagnosis of MS.

There were 366 new patients evaluated, including 236 patients with previously established MS diagnoses and 35 patients whose evaluations were not related to MS. Of the 95 patients referred for a question of MS diagnosis, 60% had clinical syndromes that were atypical for MS, 22% had normal neurologic exams, and a third had pain or sensory changes that were not localizable to the CNS.

Sixty-seven percent had MRI that was atypical for MS, and nearly half of the patients without MS had nonspecific MRI changes. “Often, these MRI changes alone prompted referral for an MS evaluation,” Dr. Kaisey and colleagues reported. “This suggests that novel, specific imaging tools may increase diagnostic confidence in the clinical setting.”

In all, the referred patients received 28 diagnoses other than MS, most commonly migraine (10 patients), anxiety or conversion disorder (9), postinfectious or idiopathic transverse myelitis (8), compression myelopathy or spondylopathy (8), and peripheral neuropathy or radiculopathy (7).

The researchers did not have any relevant disclosures.
