An updated consensus guideline on routine clinical use of magnetic resonance imaging in multiple sclerosis (MS) has been released collaboratively by three international expert groups.

The guideline represents a collaboration between the Consortium of Multiple Sclerosis Centers, the European-based Magnetic Resonance Imaging in Multiple Sclerosis, and North American Imaging in Multiple Sclerosis.

Among its recommendations for improving diagnosis and management of MS is the establishment of much-needed ways to boost protocol adherence. “The key part of these recommendations that we want to emphasize is how important it is for them to be used,” said David Li, MD, University of British Columbia, Vancouver, and cochair of the MRI guideline committee.

Dr. Li noted that there was a widespread lack of adherence among MRI centers to compliance with the 2018 CMSC guidelines in imaging for MS. This potentially compromised clinicians’ ability to identify lesions that allow for earlier and confident diagnoses and to monitor for disease changes that may necessitate the initiation or change of therapy, he said.

“The key to being able to know that brain changes have occurred in patients over time is to have scans that have been performed using standardized protocols – to be certain that the change is truly the result of a change in disease activity and progression and not erroneously due to differences resulting from different MRI scanning procedures,” he said to attendees at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

The guideline was also published this summer as a position paper in Lancet Neurology.

Key recommendations

The new guideline covers a broad range of imaging topics, with key areas of focus including the use of three-dimensional imaging, when and when not to use gadolinium contrast, and spinal cord imaging.

For example, a 3 Tesla magnet strength is preferred when imaging the brain with MRI because of its increased sensitivity for detecting lesions – but a minimum magnet strength of at least 1.5 T can also be used. For the spinal cord, there is no advantage of 3 T over 1.5 T, the guideline notes.

Other recommendations include:

• Core sequences for the brain should include sagittal and axial T2-weighted 3D fluid-attenuated inversion recovery (FLAIR), along with axial T2-weighted and diffusion-weighted sequences.
• 3D acquisition, which is now available on most scanners, is preferable to 2D acquisitions.
• Use of the subcallosal plane for consistent and reproducible alignment of axial scans is again emphasized, as it allows for easier and more confident comparison of follow-up studies to detect changes over time.
• At least two of three sagittal sequences are recommended for spinal cord MRI.
• The judicious use of macrocyclic gadolinium-based contrast agents (GBCA) is reemphasized because of its invaluable role in specific circumstances.
• However, for routine follow-up monitoring for subclinical disease activity, high-quality nonenhanced scans will allow for identification of new or enlarging T2 lesions without the need for GBCA.
• A new baseline brain MRI scan without gadolinium is recommended at least 3 months after treatment initiation, with annual follow-up scans without gadolinium.

For the diagnosis of MS, imaging of the entire spinal cord, as opposed to only the cervical segments, is recommended for the detection of lesions in the lower thoracic spinal segments and conus. However, 1.5-T scans are acceptable in that imaging, as 3-T scans provide no advantage. For routine follow-up monitoring, spinal cord MRI is optional.

“The current guidelines do not recommend routine follow-up spinal cord MRI, as it remains technically challenging and would disproportionately increase the scanning time, however experienced centers have the option to do so as a small number of asymptomatic spinal cord lesions do develop on follow-up,” the authors noted.

“However, follow up spinal cord MRI is recommended in special circumstances, including unexpected disease worsening and the possibility of a diagnosis other than multiple sclerosis,” they added.

Although the central vein sign has gained significant interest as a potential biomarker of inflammatory demyelination to help distinguish between MS and non-MS lesions, the 2021 protocol does not currently recommend imaging for the feature. However, those recommendations may change in future guidelines, the authors noted.

Low protocol adherence

The ongoing lack of adherence to guidelines that has resulted in frustrating inconsistencies in imaging was documented in no less than four studies presented at the meeting. They showed compliance with standard protocols to be strikingly poor.

Among the studies was one presented by Anthony Traboulsee, MD, professor and research chair of the MS Society of Canada, and from the University of British Columbia in Vancouver. Findings showed that only about half of scans acquired in a real-world dataset satisfied 2018 CMSC Standardized Brain MRI recommendations.

“Of note was that all the scans that were compliant were acquired in 3D while none of the 2D-acquired sequences were adherent,” Dr. Li commented.

Another study assessed use of standardized MRI protocols in a pragmatic, multisite MS clinical trial, the Traditional vs. Early Aggressive Therapy in Multiple Sclerosis (TREAT-MS) trial. Results showed that, upon enrollment, only 10% of scans followed CMSC guidelines for all three structural contrasts.

In that study, when the images provided by Johns Hopkins University Medical School were excluded, that figure dropped to 2.75% of remaining scans that met the criteria.

“Despite the importance of standardization of high-quality MRIs for the monitoring of people with MS, adoption of recommended imaging remains low,” the investigators wrote.

Resistance to change?

Commenting on the research and new guideline, Blake E. Dewey, PhD student, department of electrical and computer engineering at Johns Hopkins University, Baltimore, speculated that the noncompliance is often simply a matter of resistance to change.

“There are a number of reasons that are given for the retention of older, noncompliant MRI scans at different institutions, such as timing and patient throughput; but in my mind the issue is institutional inertia,” he said.

“It is difficult in many instances to get the clinician [radiologist] and institutional buy-in to make these kinds of changes across the board,” Mr. Dewey noted.

“The most common protocol that we see acquired is a set of 2D, low-resolution images with gaps between slices. These are simply not sufficient given modern MRI technology and the needs of MS clinicians,” he added.

Importantly, Mr. Dewey noted that, through direct communication with imaging staff and practitioners in the trial, compliance increased substantially – nearly 20-fold, “indicating a real possibility for outreach, including to commonly used outpatient radiology facilities.”

The updated MAGNIMS-CMSC-NAIMS MRI protocol is beneficial in providing “simple, reasonable guidelines that can be easily acquired at almost any imaging location in the U.S., and much of the rest of the world,” he said.

“As imaging researchers, we often reach for more that is needed clinically to properly diagnose and monitor a patient’s disease,” Mr. Dewey added. “This updated protocol has ‘trimmed the fat’ and left some discretion to institutions, which should help with compliance.”

Mr. Dewey said he also encourages imaging professionals to consider performing the sequences described as “optional” as well.

“Some of these are useful in measuring potential biomarkers currently under extensive validation, such as brain volumetrics and the central vein sign, that may help patient populations that are currently underserved by more traditional imaging, such as progressive patients and patients that could be potentially misdiagnosed,” he said.

Spreading the word

In the meantime, as part of its own outreach efforts, the CMSC is providing laminated cards that detail in simplified tables the 2021 updated MRI protocol. This makes it easy for centers to access the information and patients to help improve awareness of the protocol.

“We are urging clinicians to provide the cards to their MS patients and have them present the cards to their imaging center,” Dr. Li said. “This effort could make such an important difference in helping to encourage more to follow the protocol.”

Clinicians and patients alike can download the MRI protocol card from the CMSC website.

Many years ago, drug development in psychiatry turned to control of specific symptoms across disorders rather than within disorders, but regulatory agencies are still not yet on board, according to an expert psychopharmacologist outlining the ongoing evolution at the virtual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists, sponsored by Medscape Live.

If this reorientation is going to lead to the broad indications the newer drugs likely deserve, which is control of specific types of symptoms regardless of the diagnosis, “we have to move the [Food and Drug Administration] along,” said Stephen M. Stahl, MD, PhD, chairman of the Neuroscience Institute and an adjunct professor of psychiatry at the University of California, San Diego.

On the side of drug development and clinical practice, the reorientation has already taken place. Dr. Stahl described numerous brain circuits known to produce symptoms when function is altered that are now treatment targets. This includes the ventral medial prefrontal cortex where deficient information processing leads to depression and the orbital frontal cortex where altered function leads to impulsivity.

“It is not like each part of the brain does a little bit of everything. Rather, each part of the brain has an assignment and duty and function,” Dr. Stahl explained. By addressing the disturbed signaling in brain circuits that lead to depression, impulsivity, agitation, or other symptoms, there is an opportunity for control, regardless of the psychiatric diagnosis with which the symptom is associated.

For example, Dr. Stahl predicted that pimavanserin, a highly selective 5-HT_2A inverse agonist that is already approved for psychosis in Parkinson’s disease, is now likely to be approved for psychosis associated with other conditions on the basis of recent positive clinical studies in these other disorders.

Brexpiprazole, a serotonin-dopamine activity modulator already known to be useful for control of the agitation characteristic of schizophrenia, is now showing the same type of activity against agitation when it is associated with Alzheimer’s disease. Again, Dr. Stahl thinks this drug is on course for an indication across diseases once studies are conducted in each disease individually.

Another drug being evaluated for agitation, the N-methyl-D-aspartate receptor antagonist dextromethorphan bupropion, is also being tested for treatment of symptoms across multiple disorders, he reported.

However, the FDA has so far taken the position that each drug must be tested separately for a given symptom in each disorder for which it is being considered despite the underlying premise that it is the symptom, not the disease, that is important.

“Psychiatric disorders are syndromes, categorized by a collection of symptoms defined descriptively but not neurobiologically,” Dr. Stahl said. Unlike physiological diseases where symptoms, like a fever or abdominal cramps, are the product of a disease, psychiatric symptoms are the disease and a fundamental target – regardless of the DSM-based diagnosis.

To some degree, the symptoms of psychiatric disorders have always been the focus of treatment, but a pivot toward developing therapies that will control a symptom regardless of the underlying diagnosis is an important conceptual change. It is being made possible by advances in the detail with which the neuropathology of these symptoms is understood .

“By my count, 79 symptoms are described in DSM-5, but they are spread across hundreds of syndromes because they are grouped together in different ways,” Dr. Stahl observed.

He noted that clinicians make a diagnosis on the basis symptom groupings, but their interventions are selected to address the manifestations of the disease, not the disease itself.

“If you are a real psychopharmacologist treating real patients, you are treating the specific symptoms of the specific patient,” according to Dr. Stahl.

So far, the FDA has not made this leap, insisting on trials in these categorical disorders rather than permitting trial designs that allow benefit to be demonstrated against a symptom regardless of the syndrome with which it is associated.

Of egregious examples, Dr. Stahl recounted a recent trial of a 5-HT₂ antagonist that looked so promising against psychosis in Alzheimer’s disease that the trialists enrolled patients with psychosis regardless of type of dementia, such as vascular dementia and Lewy body disease. The efficacy was impressive.

“It worked so well that they stopped the trial, but the FDA declined to approve it,” Dr. Stahl recounted. Despite clear evidence of benefit, the regulators insisted that the investigators needed to show a significant benefit in each condition individually.

While the trial investigators acknowledged that there was not enough power in the trial to show a statistically significant benefit in each category, they argued that the overall benefit and the consistent response across categories required them to stop the trial for ethical reasons.

“That’s your problem, the FDA said to the investigators,” according to Dr. Stahl.

The failure of the FDA to recognize the efficacy of psychopharmacologic therapies across symptoms regardless of the associated disease is a failure to stay current with an important evolution in medicine, Dr. Stahl indicated.

“What we have come to understand is the neurobiology of any given symptom is likely to be the same across disorders,” he said.
 

Agency’s arbitrary decisions cited

“I completely agree with Dr. Stahl,” said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience, University of Cincinnati.

In addition to the fact that symptoms are present across multiple categories, many patients manifest multiple symptoms at one time, Dr. Nasrallah pointed out. For neurodegenerative disorders associated with psychosis, depression, anxiety, aggression, and other symptoms, it is already well known that the heterogeneous symptoms “cannot be treated with a single drug,” he said. Rather different drugs targeting each symptom individually is essential for effective management.

Dr. Nasrallah, who chaired the Psychopharmacology Update meeting, has made this point many times in the past, including in his role as the editor of Current Psychiatry. In one editorial 10 years ago, he wrote that “it makes little sense for the FDA to mandate that a drug must work for a DSM diagnosis instead of specific symptoms.”

“The FDA must update its old policy, which has led to the widespread off-label use of psychiatric drugs, an artificial concept, simply because the FDA arbitrarily decided a long time ago that new drugs must be approved for a specific DSM diagnosis,” Dr. Nasrallah said.

Dr. Stahl reported financial relationships with more than 20 pharmaceutical companies, including those that are involved in the development of drugs included in his talk. Medscape Live and this news organization are owned by the same parent company.

If this reorientation is going to lead to the broad indications the newer drugs likely deserve, which is control of specific types of symptoms regardless of the diagnosis, “we have to move the [Food and Drug Administration] along,” said Stephen M. Stahl, MD, PhD, chairman of the Neuroscience Institute and an adjunct professor of psychiatry at the University of California, San Diego.

On the side of drug development and clinical practice, the reorientation has already taken place. Dr. Stahl described numerous brain circuits known to produce symptoms when function is altered that are now treatment targets. This includes the ventral medial prefrontal cortex where deficient information processing leads to depression and the orbital frontal cortex where altered function leads to impulsivity.

“It is not like each part of the brain does a little bit of everything. Rather, each part of the brain has an assignment and duty and function,” Dr. Stahl explained. By addressing the disturbed signaling in brain circuits that lead to depression, impulsivity, agitation, or other symptoms, there is an opportunity for control, regardless of the psychiatric diagnosis with which the symptom is associated.

For example, Dr. Stahl predicted that pimavanserin, a highly selective 5-HT_2A inverse agonist that is already approved for psychosis in Parkinson’s disease, is now likely to be approved for psychosis associated with other conditions on the basis of recent positive clinical studies in these other disorders.

Brexpiprazole, a serotonin-dopamine activity modulator already known to be useful for control of the agitation characteristic of schizophrenia, is now showing the same type of activity against agitation when it is associated with Alzheimer’s disease. Again, Dr. Stahl thinks this drug is on course for an indication across diseases once studies are conducted in each disease individually.

Another drug being evaluated for agitation, the N-methyl-D-aspartate receptor antagonist dextromethorphan bupropion, is also being tested for treatment of symptoms across multiple disorders, he reported.

However, the FDA has so far taken the position that each drug must be tested separately for a given symptom in each disorder for which it is being considered despite the underlying premise that it is the symptom, not the disease, that is important.

“Psychiatric disorders are syndromes, categorized by a collection of symptoms defined descriptively but not neurobiologically,” Dr. Stahl said. Unlike physiological diseases where symptoms, like a fever or abdominal cramps, are the product of a disease, psychiatric symptoms are the disease and a fundamental target – regardless of the DSM-based diagnosis.

To some degree, the symptoms of psychiatric disorders have always been the focus of treatment, but a pivot toward developing therapies that will control a symptom regardless of the underlying diagnosis is an important conceptual change. It is being made possible by advances in the detail with which the neuropathology of these symptoms is understood .

“By my count, 79 symptoms are described in DSM-5, but they are spread across hundreds of syndromes because they are grouped together in different ways,” Dr. Stahl observed.

He noted that clinicians make a diagnosis on the basis symptom groupings, but their interventions are selected to address the manifestations of the disease, not the disease itself.

“If you are a real psychopharmacologist treating real patients, you are treating the specific symptoms of the specific patient,” according to Dr. Stahl.

So far, the FDA has not made this leap, insisting on trials in these categorical disorders rather than permitting trial designs that allow benefit to be demonstrated against a symptom regardless of the syndrome with which it is associated.

Of egregious examples, Dr. Stahl recounted a recent trial of a 5-HT₂ antagonist that looked so promising against psychosis in Alzheimer’s disease that the trialists enrolled patients with psychosis regardless of type of dementia, such as vascular dementia and Lewy body disease. The efficacy was impressive.

“It worked so well that they stopped the trial, but the FDA declined to approve it,” Dr. Stahl recounted. Despite clear evidence of benefit, the regulators insisted that the investigators needed to show a significant benefit in each condition individually.

While the trial investigators acknowledged that there was not enough power in the trial to show a statistically significant benefit in each category, they argued that the overall benefit and the consistent response across categories required them to stop the trial for ethical reasons.

“That’s your problem, the FDA said to the investigators,” according to Dr. Stahl.

The failure of the FDA to recognize the efficacy of psychopharmacologic therapies across symptoms regardless of the associated disease is a failure to stay current with an important evolution in medicine, Dr. Stahl indicated.

“What we have come to understand is the neurobiology of any given symptom is likely to be the same across disorders,” he said.
 

Agency’s arbitrary decisions cited

“I completely agree with Dr. Stahl,” said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience, University of Cincinnati.

In addition to the fact that symptoms are present across multiple categories, many patients manifest multiple symptoms at one time, Dr. Nasrallah pointed out. For neurodegenerative disorders associated with psychosis, depression, anxiety, aggression, and other symptoms, it is already well known that the heterogeneous symptoms “cannot be treated with a single drug,” he said. Rather different drugs targeting each symptom individually is essential for effective management.

Dr. Nasrallah, who chaired the Psychopharmacology Update meeting, has made this point many times in the past, including in his role as the editor of Current Psychiatry. In one editorial 10 years ago, he wrote that “it makes little sense for the FDA to mandate that a drug must work for a DSM diagnosis instead of specific symptoms.”

“The FDA must update its old policy, which has led to the widespread off-label use of psychiatric drugs, an artificial concept, simply because the FDA arbitrarily decided a long time ago that new drugs must be approved for a specific DSM diagnosis,” Dr. Nasrallah said.

Unvaccinated people who had a recent infection were five times more likely to be reinfected with the coronavirus compared to those who were fully vaccinated and didn’t have a prior infection, according to a new study published recently in the CDC’s Morbidity and Mortality Weekly Report.

The research team concluded that vaccination can provide a higher, stronger, and more consistent level of immunity against COVID-19 hospitalization than infection alone for at least six months.

“We now have additional evidence that reaffirms the importance of COVID-19 vaccines, even if you have had prior infection,” Rochelle Walensky, MD, director of the CDC, said in a statement.

“This study adds more to the body of knowledge demonstrating the protection of vaccines against severe disease from COVID-19,” she said. “The best way to stop COVID-19, including the emergence of variants, is with widespread COVID-19 vaccination and with disease prevention actions such as mask wearing, washing hands often, physical distancing and staying home when sick.”

Researchers looked at data from the VISION Network, which included more than 201,000 hospitalizations for COVID-like illness at 187 hospitals across nine states between Jan. 1 to Sept. 2. Among those, more than 94,000 had rapid testing for the coronavirus, and 7,300 had a lab-confirmed test for COVID-19.

The research team found that unvaccinated people with a prior infection within 3 to 6 months were about 5-1/2 times more likely to have laboratory-confirmed COVID-19 than those who were fully vaccinated within 3 to 6 months with the Pfizer or Moderna shots. They found similar results when looking at the months that the Delta variant was the dominant strain of the coronavirus.

Protection from the Moderna vaccine “appeared to be higher” than for the Pfizer vaccine, the study authors wrote. The boost in protection also “trended higher” among older adults, as compared to those under age 65.

Importantly, the research team noted, these estimates may change over time as immunity wanes. Future studies should consider infection-induced and vaccine-induced immunity as time passes during the pandemic, they wrote.

Additional research is also needed for the Johnson & Johnson vaccine, they wrote. Those who have received the Johnson & Johnson vaccine are currently recommended to receive a booster shot at least two months after the first shot.

Overall, “all eligible persons should be vaccinated against COVID-19 as soon as possible, including unvaccinated persons previously infected,” the research team concluded.

Oral drug administration was significantly associated with a shorter length of stay for patients treated for headache in the emergency department setting, based on data from approximately 7,000 patients.

Headache is the fourth-most common chief complaint in the ED, accounting for approximately 3% of all ED visits, said Philip Wang, a medical student at the Cleveland Clinic, in a presentation at the annual meeting of the American College of Emergency Physicians.

A variety of pharmacotherapies are used to manage headache, which leads to a range of resource use, he said.

To understand the association between route of drug administration and length of ED stay, Mr. Wang and colleagues reviewed data from 7,233 visits by 6,715 patients at any of the 21 Cleveland Clinic Health System EDs in 2018 with headache as the primary discharge diagnosis. Patients admitted to the hospital were excluded; those treated with opioids, antiemetics, and/or NSAIDs were included. The average age of the study population was 31 years, 57% were White, and approximately half were Medicaid or Medicare patients.

Approximately 68% of patients received antiemetics, 66.8% received NSAIDs, and 9.8% received opioids. Approximately 42% of patients received parenteral-only treatment and 42% received oral-only treatment; 15% received mixed treatment. The average length of ED stay was 202 minutes.

In a multivariate analysis adjusted for sex, age, income, race, insurance status, ED type, and arrival time, treatment with oral drugs only was associated with an 11% reduction of length of stay, compared with treatment with parenteral medication only (P < .001). However, the length of stay for patients treated with mixed route of administration was 10% longer, compared with parenteral only (P < .001).

In terms of drug class (a secondary outcome), patients treated with opioids had a 10% increase in length of stay (P < .01) and those treated with antiemetics had a 14% increase in length of stay; however, patients treated with NSAIDs had a 7% decrease in length of stay.

The study findings were limited in part by the challenge of isolating patients presenting with a primary headache diagnosis, Mr. Wang noted in the presentation.

The challenge of controlling for all the potential factors impacting length of stay, which is “provider, resource, and situation dependent,” is an additional limitation, he said.

However, the results show that route of administration has a significant impact on length of ED stay in patients presenting with headache, he concluded.

The study received no outside funding. The researchers disclosed no relevant financial relationships.

Influenza infection is linked to a subsequent diagnosis of Parkinson’s disease (PD) more than 10 years later, resurfacing a long-held debate about whether infection increases the risk for movement disorders over the long term.

In a large case-control study, investigators found the odds of PD were elevated by approximately 90% for PD that occurred more than 15 years after influenza infection and by more than 70% for PD occurring more than 10 years after the flu.

“This study is not definitive by any means, but it certainly suggests there are potential long-term consequences from influenza,” study investigator Noelle M. Cocoros, DSc, research scientist at Harvard Pilgrim Health Care Institute and Harvard Medical School, Boston, said in an interview.

The study was published online Oct. 25 in JAMA Neurology.

Ongoing debate

The debate about whether influenza is associated with PD has been going on as far back as the 1918 influenza pandemic, when experts documented parkinsonism in affected individuals.

Using data from the Danish patient registry, researchers identified 10,271 subjects diagnosed with PD during a 17-year period (2000-2016). Of these, 38.7% were female, and the mean age was 71.4 years.

They matched these subjects for age and sex to 51,355 controls without PD. Compared with controls, slightly fewer individuals with PD had chronic obstructive pulmonary disease (COPD) or emphysema, but there was a similar distribution of cardiovascular disease and various other conditions.

Researchers collected data on influenza diagnoses from inpatient and outpatient hospital clinics from 1977 to 2016. They plotted these by month and year on a graph, calculated the median number of diagnoses per month, and identified peaks as those with more than threefold the median.

They categorized cases in groups related to the time between the infection and PD: More than 10 years, 10-15 years, and more than 15 years.

The time lapse accounts for a rather long “run-up” to PD, said Dr. Cocoros. There’s a sometimes decades-long preclinical phase before patients develop typical motor signs and a prodromal phase where they may present with nonmotor symptoms such as sleep disorders and constipation.

“We expected there would be at least 10 years between any infection and PD if there was an association present,” said Dr. Cocoros.

Investigators found an association between influenza exposure and PD diagnosis “that held up over time,” she said.

For more than 10 years before PD, the likelihood of a diagnosis for the infected compared with the unexposed was increased 73% (odds ratio [OR] 1.73; 95% confidence interval, 1.11-2.71; P = .02) after adjustment for cardiovascular disease, diabetes, chronic obstructive pulmonary disease, emphysema, lung cancer, Crohn’s disease, and ulcerative colitis.

The odds increased with more time from infection. For more than 15 years, the adjusted OR was 1.91 (95% CI, 1.14 - 3.19; P =.01).

However, for the 10- to 15-year time frame, the point estimate was reduced and the CI nonsignificant (OR, 1.33; 95% CI, 0.54-3.27; P = .53). This “is a little hard to interpret,” but could be a result of the small numbers, exposure misclassification, or because “the longer time interval is what’s meaningful,” said Dr. Cocoros.
 

Potential COVID-19–related PD surge?

In a sensitivity analysis, researchers looked at peak infection activity. “We wanted to increase the likelihood of these diagnoses representing actual infection,” Dr. Cocoros noted.

Here, the OR was still elevated at more than 10 years, but the CI was quite wide and included 1 (OR, 1.52; 95% CI, 0.80-2.89; P = .21). “So the association holds up, but the estimates are quite unstable,” said Dr. Cocoros.

Researchers examined associations with numerous other infection types, but did not see the same trend over time. Some infections – for example, gastrointestinal infections and septicemia – were associated with PD within 5 years, but most associations appeared to be null after more than 10 years.

“There seemed to be associations earlier between the infection and PD, which we interpret to suggest there’s actually not a meaningful association,” said Dr. Cocoros.

An exception might be urinary tract infections (UTIs), where after 10 years, the adjusted OR was 1.19 (95% CI, 1.01-1.40). Research suggests patients with PD often have UTIs and neurogenic bladder.

“It’s possible that UTIs could be an early symptom of PD rather than a causative factor,” said Dr. Cocoros.

It’s unclear how influenza might lead to PD but it could be that the virus gets into the central nervous system, resulting in neuroinflammation. Cytokines generated in response to the influenza infection might damage the brain.

“The infection could be a ‘primer’ or an initial ‘hit’ to the system, maybe setting people up for PD,” said Dr. Cocoros.

As for the current COVID-19 pandemic, some experts are concerned about a potential surge in PD cases in decades to come, and are calling for prospective monitoring of patients with this infection, said Dr. Cocoros.

However, she noted that infections don’t account for all PD cases and that genetic and environmental factors also influence risk.

Many individuals who contract influenza don’t seek medical care or get tested, so it’s possible the study counted those who had the infection as unexposed. Another potential study limitation was that small numbers for some infections, for example, Helicobacter pylori and hepatitis C, limited the ability to interpret results.
 

‘Exciting and important’ findings

Commenting on the research for this news organization, Aparna Wagle Shukla, MD, professor, Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, said the results amid the current pandemic are “exciting and important” and “have reinvigorated interest” in the role of infection in PD.

However, the study had some limitations, an important one being lack of accounting for confounding factors, including environmental factors, she said. Exposure to pesticides, living in a rural area, drinking well water, and having had a head injury may increase PD risk, whereas high intake of caffeine, nicotine, alcohol, and nonsteroidal anti-inflammatory drugs might lower the risk.

The researchers did not take into account exposure to multiple microbes or “infection burden,” said Dr. Wagle Shukla, who was not involved in the current study. In addition, as the data are from a single country with exposure to specific influenza strains, application of the findings elsewhere may be limited.

Dr. Wagle Shukla noted that a case-control design “isn’t ideal” from an epidemiological perspective. “Future studies should involve large cohorts followed longitudinally.”

The study was supported by grants from the Lundbeck Foundation and the Augustinus Foundation. Dr. Cocoros has disclosed no relevant financial relationships. Several coauthors have disclosed relationships with industry. The full list can be found with the original article.

In addition, as the data are from a single country with exposure to specific influenza strains, application of the findings elsewhere may be limited.

Dr. Wagle Shukla noted that a case-control design “isn’t ideal” from an epidemiological perspective. “Future studies should involve large cohorts followed longitudinally.”

Influenza infection is linked to a subsequent diagnosis of Parkinson’s disease (PD) more than 10 years later, resurfacing a long-held debate about whether infection increases the risk for movement disorders over the long term.

In a large case-control study, investigators found the odds of PD were elevated by approximately 90% for PD that occurred more than 15 years after influenza infection and by more than 70% for PD occurring more than 10 years after the flu.

“This study is not definitive by any means, but it certainly suggests there are potential long-term consequences from influenza,” study investigator Noelle M. Cocoros, DSc, research scientist at Harvard Pilgrim Health Care Institute and Harvard Medical School, Boston, said in an interview.

The study was published online Oct. 25 in JAMA Neurology.

Ongoing debate

The debate about whether influenza is associated with PD has been going on as far back as the 1918 influenza pandemic, when experts documented parkinsonism in affected individuals.

Using data from the Danish patient registry, researchers identified 10,271 subjects diagnosed with PD during a 17-year period (2000-2016). Of these, 38.7% were female, and the mean age was 71.4 years.

They matched these subjects for age and sex to 51,355 controls without PD. Compared with controls, slightly fewer individuals with PD had chronic obstructive pulmonary disease (COPD) or emphysema, but there was a similar distribution of cardiovascular disease and various other conditions.

Researchers collected data on influenza diagnoses from inpatient and outpatient hospital clinics from 1977 to 2016. They plotted these by month and year on a graph, calculated the median number of diagnoses per month, and identified peaks as those with more than threefold the median.

They categorized cases in groups related to the time between the infection and PD: More than 10 years, 10-15 years, and more than 15 years.

The time lapse accounts for a rather long “run-up” to PD, said Dr. Cocoros. There’s a sometimes decades-long preclinical phase before patients develop typical motor signs and a prodromal phase where they may present with nonmotor symptoms such as sleep disorders and constipation.

“We expected there would be at least 10 years between any infection and PD if there was an association present,” said Dr. Cocoros.

Investigators found an association between influenza exposure and PD diagnosis “that held up over time,” she said.

For more than 10 years before PD, the likelihood of a diagnosis for the infected compared with the unexposed was increased 73% (odds ratio [OR] 1.73; 95% confidence interval, 1.11-2.71; P = .02) after adjustment for cardiovascular disease, diabetes, chronic obstructive pulmonary disease, emphysema, lung cancer, Crohn’s disease, and ulcerative colitis.

The odds increased with more time from infection. For more than 15 years, the adjusted OR was 1.91 (95% CI, 1.14 - 3.19; P =.01).

However, for the 10- to 15-year time frame, the point estimate was reduced and the CI nonsignificant (OR, 1.33; 95% CI, 0.54-3.27; P = .53). This “is a little hard to interpret,” but could be a result of the small numbers, exposure misclassification, or because “the longer time interval is what’s meaningful,” said Dr. Cocoros.
 

Potential COVID-19–related PD surge?

In a sensitivity analysis, researchers looked at peak infection activity. “We wanted to increase the likelihood of these diagnoses representing actual infection,” Dr. Cocoros noted.

Here, the OR was still elevated at more than 10 years, but the CI was quite wide and included 1 (OR, 1.52; 95% CI, 0.80-2.89; P = .21). “So the association holds up, but the estimates are quite unstable,” said Dr. Cocoros.

Researchers examined associations with numerous other infection types, but did not see the same trend over time. Some infections – for example, gastrointestinal infections and septicemia – were associated with PD within 5 years, but most associations appeared to be null after more than 10 years.

“There seemed to be associations earlier between the infection and PD, which we interpret to suggest there’s actually not a meaningful association,” said Dr. Cocoros.

An exception might be urinary tract infections (UTIs), where after 10 years, the adjusted OR was 1.19 (95% CI, 1.01-1.40). Research suggests patients with PD often have UTIs and neurogenic bladder.

“It’s possible that UTIs could be an early symptom of PD rather than a causative factor,” said Dr. Cocoros.

It’s unclear how influenza might lead to PD but it could be that the virus gets into the central nervous system, resulting in neuroinflammation. Cytokines generated in response to the influenza infection might damage the brain.

“The infection could be a ‘primer’ or an initial ‘hit’ to the system, maybe setting people up for PD,” said Dr. Cocoros.

As for the current COVID-19 pandemic, some experts are concerned about a potential surge in PD cases in decades to come, and are calling for prospective monitoring of patients with this infection, said Dr. Cocoros.

However, she noted that infections don’t account for all PD cases and that genetic and environmental factors also influence risk.

Many individuals who contract influenza don’t seek medical care or get tested, so it’s possible the study counted those who had the infection as unexposed. Another potential study limitation was that small numbers for some infections, for example, Helicobacter pylori and hepatitis C, limited the ability to interpret results.
 

‘Exciting and important’ findings

Commenting on the research for this news organization, Aparna Wagle Shukla, MD, professor, Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, said the results amid the current pandemic are “exciting and important” and “have reinvigorated interest” in the role of infection in PD.

However, the study had some limitations, an important one being lack of accounting for confounding factors, including environmental factors, she said. Exposure to pesticides, living in a rural area, drinking well water, and having had a head injury may increase PD risk, whereas high intake of caffeine, nicotine, alcohol, and nonsteroidal anti-inflammatory drugs might lower the risk.

The researchers did not take into account exposure to multiple microbes or “infection burden,” said Dr. Wagle Shukla, who was not involved in the current study.

Sleeping too much or too little can lead to cognitive decline over time, but new research suggests there could be a sleep time “sweet spot” that stabilizes cognitive function.

In a longitudinal study, investigators found older adults who slept less than 4.5 hours or more than 6.5 hours a night reported significant cognitive decline over time, but cognitive scores for those with sleep duration in between that range remained stable.

“This really suggests that there’s this middle range, a ‘sweet spot,’ where your sleep is really optimal,” lead author Brendan Lucey, MD, MSCI, associate professor of neurology and director of the Washington University Sleep Medicine Center, St. Louis, said in an interview.

The study, published online Oct. 20, 2021, in the journal Brain, is part of a growing body of research that seeks to determine if sleep can be used as a marker of Alzheimer’s disease progression.
 

A complex relationship

Studies suggest a strong relationship between sleep patterns and Alzheimer’s disease, which affects nearly 6 million Americans. The challenge, Dr. Lucey said, is unwinding the complex links between sleep, AD, and cognitive function.

An earlier study by Dr. Lucey and colleagues found that poor sleep quality is associated with early signs of AD, and a report published in September found that elderly people who slept less than 6 hours a night had a greater burden of amyloid-beta, a hallmark sign of AD.

For this new study, researchers monitored sleep-wake activity over 4-6 nights in 100 participants who underwent annual cognitive assessments and clinical studies, including APOE genotyping, as part of a longitudinal study at the Knight Alzheimer Disease Research Center at Washington University.

Participants also provided cerebrospinal fluid (CSF) total tau and amyloid-beta 42 and wore a small EEG device on their forehead while they slept.

The majority of participants had a clinical dementia rating (CDR) score of 0, indicating no cognitive impairment. Twelve individuals had a CDR greater than 0, with most reporting mild cognitive impairment.

As expected, CSF analysis showed greater evidence of AD pathology in those with a baseline CDR greater than 0.

Changes in cognitive function were measured using a Preclinical Alzheimer Cognitive Composite (PACC) score, a composite of results from a neuropsychological testing battery that included the Free and Cued Selective Reminding Test, the Logical Memory Delayed Recall Test from the Wechsler Memory Scale–Revised, the Digit Symbol Substitution Test from the Wechsler Adult Intelligence Scale–Revised, and the Mini-Mental State Examination.

Researchers found an upside-down U-shaped relationship between PACC scores and sleep duration, with dramatic cognitive decline in those who slept less than 4.5 hours or more than 6.5 hours a night (P < .001 for both).

The U-shaped relationship was also found with measures of sleep phases, including time spent in rapid eye movement and in non-REM sleep (P < .001 for both).

The findings persisted even after controlling for confounders that can affect sleep and cognition, such as age, CSF total tau/amyloid-beta ₄₂ ratio, apo E four-allele carrier status, years of education, and sex.

Understanding how sleep changes at different stages of AD could help researchers determine if sleep can be used as a marker of disease progression, Dr. Lucey said. That could lead to interventions to slow that process.

“We’re not at the point yet where we can say that we need to monitor someone’s sleep time and then do an intervention to see if it would improve their risk for cognitive decline,” said Dr. Lucey, who plans to repeat this sleep study with the same cohort to track changes in sleep patterns and cognitive function over time. “But that’s a question I’m very excited to try to answer.”
 

A component of cognitive health

Commenting on the findings for this news organization, Heather Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, noted that the study adds to a body of evidence linking sleep and cognition, especially how sleep quality can optimize brain function.

“We’ve seen previous research that’s shown poor sleep contributes to dementia risk, as well as research showing sleep duration may play a role in cognition,” she said.

“We also need studies that look at sleep as an intervention for cognitive health,” Dr. Snyder said. “Sleep is an important aspect of our overall health. Clinicians should have conversations with their patients about sleep as part of standard discussions about their health habits and wellness.”

The study was funded by the National Institutes of Health, the American Sleep Medicine Foundation, the Roger and Paula Riney Fund, and the Daniel J. Brennan, MD Fund. Dr. Lucey consults for Merck and Eli Lilly. Dr. Snyder has disclosed no relevant financial relationships.

James Nicholas Brenton, M.D., is the director of the University of Virginia’s Pediatric and Young Adult MS and Related Disorders Clinic. He is also associate professor of neurology and pediatrics for clinical research and performs collaborative clinical research within the field of pediatric MS. His research focuses on pediatric demyelinating disease and autoimmune epilepsies.

As the director of a clinic focusing on pediatric and young adults MS and related disorders, how do modifiable risk factors such as obesity, smoking, et cetera, increase the risk of MS in general?

Dr. Brenton: There are several risk factors for pediatric-onset MS. When I say pediatric-onset, I'm referring to patients with clinical onset of MS prior to the age of 18 years. Some MS risk factors are not considered “modifiable,” such as genetic risks. The greatest genetic risk for MS is related to specific haplotypes in the HLA-DRB1 gene. Another risk factor that is less amenable to modification is early exposure to certain viruses, like the Epstein-Barr virus (Makhani, et al 2016).

On the other hand, there are several potentially modifiable risk factors for MS. This includes smoking - either first or second-hand smoke. In the case of pediatric MS patients, it is most often related to second-hand (or passive) smoke exposure (Lavery, et al 2019). Another example of a modifiable MS risk factor is vitamin D deficiency. Vitamin D levels are influenced significantly by duration and intensity of direct exposure to sunlight, which depends (in part) on the geographic location of where you grow up. For example, those who live at higher latitudes (e.g. live further away from the equator) have less exposure to direct sunlight than a child who lives at lower latitudes (e.g. closer to the equator) (Banwell, et al  2011).

Obesity during childhood or adolescence is another modifiable risk factor for MS. Obesity’s risk for MS (like smoking) is dose-dependent – meaning, the more obese that you are, the higher your overall risk for future development of MS. In fact, the BMI in children with MS is markedly higher than their non-MS peers, and begins in early childhood, years before the clinical onset of the disease (Brenton, et al 2019).

There is mixed evidence regarding the impact of certain perinatal factors on future risk for MS. For example, some literature suggests that Caesarean delivery increases the risk of MS (Maghzi, et al 2012). Our research has found that infantile breastfeeding is associated with a lower future risk of pediatric-onset MS (Brenton, et al 2017).

Children are two to three times more likely to experience MS relapses compared with adults. How likely is it for the childhood obesity epidemic to lead to increased morbidity from MS or CIS, particularly in adolescent girls?

Dr. Brenton:  Obesity is a systemic disease that manifests as excessive or abnormal accumulation of body fat. We know that chronic obesity leads to higher overall morbidity, lower quality of life, and reduced life expectancy. There are several common co-morbidities associated with obesity - like cardiovascular disease, type II diabetes mellitus, hypertension, polycystic ovarian syndrome, dyslipidemia, infertility, and some cancers (Abdelaal, et al 2017). Certainly, all these implications for the general population would pertain to those with MS who exhibit chronic obesity.

While we have fairly good evidence that obesity is a causal risk factor for the development of MS, there actually is a paucity of literature that has studied the impact of persistent obesity on an already established MS disease state. Several recent studies show that obesity is associated with a pro-inflammatory state in the blood and cerebrospinal fluid of MS patients (Stampanoni, et al 2019). There are other studies that shown a direct association between MS-related neurologic disability and obesity – such that those with a greater waist circumference exhibit higher rates of neurologic disability (Fitzgerald, et al 2019).

Recent studies have assessed whether SNAP factors are associated with health outcomes. How does a modifiable SNAP risk score in people with multiple sclerosis impacts the likelihood of disability worsening??

Dr. Brenton: SNAP factors may not be as well known to some people in this field. SNAP factors refer to smoking (“S”), poor nutrition (“N”), alcohol consumption (“A”) and insufficient physical activity (“P”). These four factors appear to be the most preventable causes of morbidity within the general population. SNAP factors are common in people with MS. The most common SNAP factors in MS patients are poor nutrition and insufficient physical activity. Cross-sectionally, these factors appear to be associated with worsening neurologic disability (Marck, et al 2019).

There is data suggesting that SNAP factors, particularly those that increase over time, can associate with worsening disability when followed over several years. Importantly, your baseline SNAP score does not appear to predict your future level of disability (Marck, et al 2019). Collective SNAP scores have not yet been well-studied in pediatric MS patients, but are important to study - particularly given that children with MS reach maximum neurologic disability at a younger age than adult-onset MS patients (Renoux, et al 2007).

What are some of the best practices MS health care providers can engage in to promote exercise and rehabilitative protocols to significantly impact the physical and cognitive performance of MS patients?

Dr. Brenton: Even though pediatric MS patients exhibit relatively low levels of physical neurologic disability early in their disease, the physical activity levels of youth with MS are quite low. These patients engage in less moderate and vigorous physical activity when you compare them to their non-MS peers (Grover, et al 2016), but we still don't fully understand why this is the case. In fact, it may be related to several different factors - including pain, fatigue, sleep quality, MS disease activity, and psychological factors (such as depression, social anxiety, and perceptions of self-efficacy). In order to truly provide patient-specific interventions that positively impact physical activity we need to better understand what factors to study and how these factors play into the individual patient. For example, if high levels of fatigue are inhibiting a patient from being physically active, the provider should explore sources of fatigue: “how are sleep patterns?”, “are they napping throughout the day?”, “does the fatigue occur only after a period of physical activity, or is it persistent despite how active they are?” These are examples of questions that may lead a neurologist to different approaches for managing reduced physical activity.

Generally speaking however, pediatric and adult MS providers would ideally provide healthy nutrition guidance and counseling to all patients, regardless of their weight. Though there is no particular proven “MS diet,” in general, we recommend a balanced diet that is lower in saturated fats and processed sugars and higher in fruits and vegetables. In the case of a pediatric MS patient, it's important to have the family on board with consuming a healthier diet, as parental involvement increases the likelihood of healthy behavioral changes in the child.

It is important to ask patients targeted questions about their physical activity and assist with goal setting toward achievable targets. If the patient is receptive, a provider can advise on the use of digital interventions, like apps or internet-based social groups that incorporate education, accountability, and self-monitoring. What we do not know yet, but hope to know soon, is if physical activity and/or reducing obesity/improving diet can serve as a modifier of disease in kids and adults with MS. My current research is focused on studying the role of obesity and diet on the clinical course of children with MS. Many others are studying the role of physical activity on the disease course of children with MS. Suffice to say, there is much more to learn on the role of diet, body composition, and physical activity in youth with MS.

For example, if high levels of fatigue are inhibiting a patient from being physically active, the provider should explore sources of fatigue: “how are sleep patterns?”, “are they napping throughout the day?”, “does the fatigue occur only after a period of physical activity, or is it persistent despite how active they are?” These are examples of questions that may lead a neurologist to different approaches for managing reduced physical activity.

Generally speaking however, pediatric and adult MS providers would ideally provide healthy nutrition guidance and counseling to all patients, regardless of their weight. Though there is no particular proven “MS diet,” in general, we recommend a balanced diet that is lower in saturated fats and processed sugars and higher in fruits and vegetables. In the case of a pediatric MS patient, it's important to have the family on board with consuming a healthier diet, as parental involvement increases the likelihood of healthy behavioral changes in the child.

It is important to ask patients targeted questions about their physical activity and assist with goal setting toward achievable targets. If the patient is receptive, a provider can advise on the use of digital interventions, like apps or internet-based social groups that incorporate education, accountability, and self-monitoring. What we do not know yet, but hope to know soon, is if physical activity and/or reducing obesity/improving diet can serve as a modifier of disease in kids and adults with MS. My current research is focused on studying the role of obesity and diet on the clinical course of children with MS. Many others are studying the role of physical activity on the disease course of children with MS. Suffice to say, there is much more to learn on the role of diet, body composition, and physical activity in youth with MS.

James Nicholas Brenton, M.D., is the director of the University of Virginia’s Pediatric and Young Adult MS and Related Disorders Clinic. He is also associate professor of neurology and pediatrics for clinical research and performs collaborative clinical research within the field of pediatric MS. His research focuses on pediatric demyelinating disease and autoimmune epilepsies.

As the director of a clinic focusing on pediatric and young adults MS and related disorders, how do modifiable risk factors such as obesity, smoking, et cetera, increase the risk of MS in general?

Dr. Brenton: There are several risk factors for pediatric-onset MS. When I say pediatric-onset, I'm referring to patients with clinical onset of MS prior to the age of 18 years. Some MS risk factors are not considered “modifiable,” such as genetic risks. The greatest genetic risk for MS is related to specific haplotypes in the HLA-DRB1 gene. Another risk factor that is less amenable to modification is early exposure to certain viruses, like the Epstein-Barr virus (Makhani, et al 2016).

On the other hand, there are several potentially modifiable risk factors for MS. This includes smoking - either first or second-hand smoke. In the case of pediatric MS patients, it is most often related to second-hand (or passive) smoke exposure (Lavery, et al 2019). Another example of a modifiable MS risk factor is vitamin D deficiency. Vitamin D levels are influenced significantly by duration and intensity of direct exposure to sunlight, which depends (in part) on the geographic location of where you grow up. For example, those who live at higher latitudes (e.g. live further away from the equator) have less exposure to direct sunlight than a child who lives at lower latitudes (e.g. closer to the equator) (Banwell, et al  2011).

Obesity during childhood or adolescence is another modifiable risk factor for MS. Obesity’s risk for MS (like smoking) is dose-dependent – meaning, the more obese that you are, the higher your overall risk for future development of MS. In fact, the BMI in children with MS is markedly higher than their non-MS peers, and begins in early childhood, years before the clinical onset of the disease (Brenton, et al 2019).

There is mixed evidence regarding the impact of certain perinatal factors on future risk for MS. For example, some literature suggests that Caesarean delivery increases the risk of MS (Maghzi, et al 2012). Our research has found that infantile breastfeeding is associated with a lower future risk of pediatric-onset MS (Brenton, et al 2017).

Children are two to three times more likely to experience MS relapses compared with adults. How likely is it for the childhood obesity epidemic to lead to increased morbidity from MS or CIS, particularly in adolescent girls?

Dr. Brenton:  Obesity is a systemic disease that manifests as excessive or abnormal accumulation of body fat. We know that chronic obesity leads to higher overall morbidity, lower quality of life, and reduced life expectancy. There are several common co-morbidities associated with obesity - like cardiovascular disease, type II diabetes mellitus, hypertension, polycystic ovarian syndrome, dyslipidemia, infertility, and some cancers (Abdelaal, et al 2017). Certainly, all these implications for the general population would pertain to those with MS who exhibit chronic obesity.

While we have fairly good evidence that obesity is a causal risk factor for the development of MS, there actually is a paucity of literature that has studied the impact of persistent obesity on an already established MS disease state. Several recent studies show that obesity is associated with a pro-inflammatory state in the blood and cerebrospinal fluid of MS patients (Stampanoni, et al 2019). There are other studies that shown a direct association between MS-related neurologic disability and obesity – such that those with a greater waist circumference exhibit higher rates of neurologic disability (Fitzgerald, et al 2019).

Recent studies have assessed whether SNAP factors are associated with health outcomes. How does a modifiable SNAP risk score in people with multiple sclerosis impacts the likelihood of disability worsening??

Dr. Brenton: SNAP factors may not be as well known to some people in this field. SNAP factors refer to smoking (“S”), poor nutrition (“N”), alcohol consumption (“A”) and insufficient physical activity (“P”). These four factors appear to be the most preventable causes of morbidity within the general population. SNAP factors are common in people with MS. The most common SNAP factors in MS patients are poor nutrition and insufficient physical activity. Cross-sectionally, these factors appear to be associated with worsening neurologic disability (Marck, et al 2019).

There is data suggesting that SNAP factors, particularly those that increase over time, can associate with worsening disability when followed over several years. Importantly, your baseline SNAP score does not appear to predict your future level of disability (Marck, et al 2019). Collective SNAP scores have not yet been well-studied in pediatric MS patients, but are important to study - particularly given that children with MS reach maximum neurologic disability at a younger age than adult-onset MS patients (Renoux, et al 2007).

What are some of the best practices MS health care providers can engage in to promote exercise and rehabilitative protocols to significantly impact the physical and cognitive performance of MS patients?

Dr. Brenton: Even though pediatric MS patients exhibit relatively low levels of physical neurologic disability early in their disease, the physical activity levels of youth with MS are quite low. These patients engage in less moderate and vigorous physical activity when you compare them to their non-MS peers (Grover, et al 2016), but we still don't fully understand why this is the case. In fact, it may be related to several different factors - including pain, fatigue, sleep quality, MS disease activity, and psychological factors (such as depression, social anxiety, and perceptions of self-efficacy). In order to truly provide patient-specific interventions that positively impact physical activity we need to better understand what factors to study and how these factors play into the individual patient. For example, if high levels of fatigue are inhibiting a patient from being physically active, the provider should explore sources of fatigue: “how are sleep patterns?”, “are they napping throughout the day?”, “does the fatigue occur only after a period of physical activity, or is it persistent despite how active they are?” These are examples of questions that may lead a neurologist to different approaches for managing reduced physical activity.

Inside the emergency department at Sparrow Hospital in Lansing, Mich., staff members are struggling to care for patients showing up much sicker than they’ve ever seen.

Tiffani Dusang, the ER’s nursing director, practically vibrates with pent-up anxiety, looking at patients lying on a long line of stretchers pushed up against the beige walls of the hospital hallways. “It’s hard to watch,” she said in a warm Texas twang.

But there’s nothing she can do. The ER’s 72 rooms are already filled.

“I always feel very, very bad when I walk down the hallway and see that people are in pain, or needing to sleep, or needing quiet. But they have to be in the hallway with, as you can see, 10 or 15 people walking by every minute,” Ms. Dusang said.

The scene is a stark contrast to where this emergency department — and thousands of others — were at the start of the pandemic. Except for initial hot spots like New York City, in spring 2020 many ERs across the country were often eerily empty. Terrified of contracting COVID-19, people who were sick with other things did their best to stay away from hospitals. Visits to emergency rooms dropped to half their typical levels, according to the Epic Health Research Network, and didn’t fully rebound until this summer.

But now, they’re too full. Even in parts of the country where covid isn’t overwhelming the health system, patients are showing up to the ER sicker than before the pandemic, their diseases more advanced and in need of more complicated care.

Months of treatment delays have exacerbated chronic conditions and worsened symptoms. Doctors and nurses say the severity of illness ranges widely and includes abdominal pain, respiratory problems, blood clots, heart conditions and suicide attempts, among other conditions.

But they can hardly be accommodated. Emergency departments, ideally, are meant to be brief ports in a storm, with patients staying just long enough to be sent home with instructions to follow up with primary care physicians, or sufficiently stabilized to be transferred “upstairs” to inpatient or intensive care units.

Except now those long-term care floors are full too, with a mix of covid and non-covid patients. People coming to the ER get warehoused for hours, even days, forcing ER staffers to perform long-term care roles they weren’t trained to do.

At Sparrow, space is a valuable commodity in the ER: A separate section of the hospital was turned into an overflow unit. Stretchers stack up in halls. A row of brown reclining chairs lines a wall, intended for patients who aren’t sick enough for a stretcher but are too sick to stay in the main waiting room.

Forget privacy, Alejos Perrientoz learned when he arrived. He came to the ER because his arm had been tingling and painful for over a week. He couldn’t hold a cup of coffee. A nurse gave him a full physical exam in a brown recliner, which made him self-conscious about having his shirt lifted in front of strangers. “I felt a little uncomfortable,” he whispered. “But I have no choice, you know? I’m in the hallway. There’s no rooms.

“We could have done the physical in the parking lot,” he added, managing a laugh.

Even patients who arrive by ambulance are not guaranteed a room: One nurse runs triage, screening those who absolutely need a bed, and those who can be put in the waiting area.

“I hate that we even have to make that determination,” MS. Dusang said. Lately, staff members have been pulling out some patients already in the ER’s rooms when others arrive who are more critically ill. “No one likes to take someone out of the privacy of their room and say, ‘We’re going to put you in a hallway because we need to get care to someone else.’”

ER patients have grown sicker

“We are hearing from members in every part of the country,” said Dr. Lisa Moreno, president of the American Academy of Emergency Medicine. “The Midwest, the South, the Northeast, the West … they are seeing this exact same phenomenon.”

Although the number of ER visits returned to pre-COVID levels this summer, admission rates, from the ER to the hospital’s inpatient floors, are still almost 20% higher. That’s according to the most recent analysis by the Epic Health Research Network, which pulls data from more than 120 million patients across the country.

“It’s an early indicator that what’s happening in the ED is that we’re seeing more acute cases than we were pre-pandemic,” said Caleb Cox, a data scientist at Epic.

Less acute cases, such as people with health issues like rashes or conjunctivitis, still aren’t going to the ER as much as they used to. Instead, they may be opting for an urgent care center or their primary care doctor, Mr. Cox explained. Meanwhile, there has been an increase in people coming to the ER with more serious conditions, like strokes and heart attacks.

So, even though the total number of patients coming to ERs is about the same as before the pandemic, “that’s absolutely going to feel like [if I’m an ER doctor or nurse] I’m seeing more patients and I’m seeing more acute patients,” Mr. Cox said.

Dr. Moreno, the AAEM president, works at an emergency department in New Orleans. She said the level of illness, and the inability to admit patients quickly and move them to beds upstairs, has created a level of chaos she described as “not even humane.”

At the beginning of a recent shift, she heard a patient crying nearby and went to investigate. It was a paraplegic man who’d recently had surgery for colon cancer. His large post-operative wound was sealed with a device called a wound vac, which pulls fluid from the wound into a drainage tube attached to a portable vacuum pump.

But the wound vac had malfunctioned, which is why he had come to the ER. Staffers were so busy, however, that by the time Dr. Moreno came in, the fluid from his wound was leaking everywhere.

“When I went in, the bed was covered,” she recalled. “I mean, he was lying in a puddle of secretions from this wound. And he was crying, because he said to me, ‘I’m paralyzed. I can’t move to get away from all these secretions, and I know I’m going to end up getting an infection. I know I’m going to end up getting an ulcer. I’ve been laying in this for, like, eight or nine hours.’”

The nurse in charge of his care told Dr. Moreno she simply hadn’t had time to help this patient yet. “She said, ‘I’ve had so many patients to take care of, and so many critical patients. I started [an IV] drip on this person. This person is on a cardiac monitor. I just didn’t have time to get in there.’”

“This is not humane care,” Dr. Moreno said. “This is horrible care.”

But it’s what can happen when emergency department staffers don’t have the resources they need to deal with the onslaught of competing demands.

“All the nurses and doctors had the highest level of intent to do the right thing for the person,” Dr. Moreno said. “But because of the high acuity of … a large number of patients, the staffing ratio of nurse to patient, even the staffing ratio of doctor to patient, this guy did not get the care that he deserved to get, just as a human being.”

The instance of unintended neglect that Dr. Moreno saw is extreme, and not the experience of most patients who arrive at ERs these days. But the problem is not new: Even before the pandemic, ER overcrowding had been a “widespread problem and a source of patient harm, according to a recent commentary in NEJM Catalyst Innovations in Care Delivery.

“ED crowding is not an issue of inconvenience,” the authors wrote. “There is incontrovertible evidence that ED crowding leads to significant patient harm, including morbidity and mortality related to consequential delays of treatment for both high- and low-acuity patients.”

And already-overwhelmed staffers are burning out.

Burnout feeds staffing shortages, and vice versa

Every morning, Tiffani Dusang wakes up and checks her Sparrow email with one singular hope: that she will not see yet another nurse resignation letter in her inbox.

“I cannot tell you how many of them [the nurses] tell me they went home crying” after their shifts, she said.

Despite Ms. Dusang’s best efforts to support her staffers, they’re leaving too fast to be replaced, either to take higher-paying gigs as a travel nurse, to try a less-stressful type of nursing, or simply walking away from the profession entirely.

Kelly Spitz has been an emergency department nurse at Sparrow for 10 years. But, lately, she has also fantasized about leaving. “It has crossed my mind several times,” she said, and yet she continues to come back. “Because I have a team here. And I love what I do.” But then she started to cry. The issue is not the hard work, or even the stress. She struggles with not being able to give her patients the kind of care and attention she wants to give them, and that they need and deserve, she said.

She often thinks about a patient whose test results revealed terminal cancer, she said. Ms. Spitz spent all day working the phones, hustling case managers, trying to get hospice care set up in the man’s home. He was going to die, and she just didn’t want him to have to die in the hospital, where only one visitor was allowed. She wanted to get him home, and back with his family.

Finally, after many hours, they found an ambulance to take him home.

Three days later, the man’s family members called Ms. Spitz: He had died surrounded by family. They were calling to thank her.

“I felt like I did my job there, because I got him home,” she said. But that’s a rare feeling these days. “I just hope it gets better. I hope it gets better soon.”

Around 4 p.m. at Sparrow Hospital as one shift approached its end, Ms. Dusang faced a new crisis: The overnight shift was more short-staffed than usual.

“Can we get two inpatient nurses?” she asked, hoping to borrow two nurses from one of the hospital floors upstairs.

“Already tried,” replied nurse Troy Latunski.

Without more staff, it’s going to be hard to care for new patients who come in overnight — from car crashes to seizures or other emergencies.

But Mr. Latunski had a plan: He would go home, snatch a few hours of sleep and return at 11 p.m. to work the overnight shift in the ER’s overflow unit. That meant he would be largely caring for eight patients, alone. On just a few short hours of sleep. But lately that seemed to be their only, and best, option.

Ms. Dusang considered for a moment, took a deep breath and nodded. “OK,” she said.

“Go home. Get some sleep. Thank you,” she added, shooting Mr. Latunski a grateful smile. And then she pivoted, because another nurse was approaching with an urgent question. On to the next crisis.

Lately, staff members have been pulling out some patients already in the ER’s rooms when others arrive who are more critically ill. “No one likes to take someone out of the privacy of their room and say, ‘We’re going to put you in a hallway because we need to get care to someone else.’”

ER patients have grown sicker

“We are hearing from members in every part of the country,” said Dr. Lisa Moreno, president of the American Academy of Emergency Medicine. “The Midwest, the South, the Northeast, the West … they are seeing this exact same phenomenon.”

Although the number of ER visits returned to pre-COVID levels this summer, admission rates, from the ER to the hospital’s inpatient floors, are still almost 20% higher. That’s according to the most recent analysis by the Epic Health Research Network, which pulls data from more than 120 million patients across the country.

“It’s an early indicator that what’s happening in the ED is that we’re seeing more acute cases than we were pre-pandemic,” said Caleb Cox, a data scientist at Epic.

Less acute cases, such as people with health issues like rashes or conjunctivitis, still aren’t going to the ER as much as they used to. Instead, they may be opting for an urgent care center or their primary care doctor, Mr. Cox explained. Meanwhile, there has been an increase in people coming to the ER with more serious conditions, like strokes and heart attacks.

So, even though the total number of patients coming to ERs is about the same as before the pandemic, “that’s absolutely going to feel like [if I’m an ER doctor or nurse] I’m seeing more patients and I’m seeing more acute patients,” Mr. Cox said.

Dr. Moreno, the AAEM president, works at an emergency department in New Orleans. She said the level of illness, and the inability to admit patients quickly and move them to beds upstairs, has created a level of chaos she described as “not even humane.”

At the beginning of a recent shift, she heard a patient crying nearby and went to investigate. It was a paraplegic man who’d recently had surgery for colon cancer. His large post-operative wound was sealed with a device called a wound vac, which pulls fluid from the wound into a drainage tube attached to a portable vacuum pump.

But the wound vac had malfunctioned, which is why he had come to the ER. Staffers were so busy, however, that by the time Dr. Moreno came in, the fluid from his wound was leaking everywhere.

“When I went in, the bed was covered,” she recalled. “I mean, he was lying in a puddle of secretions from this wound. And he was crying, because he said to me, ‘I’m paralyzed. I can’t move to get away from all these secretions, and I know I’m going to end up getting an infection. I know I’m going to end up getting an ulcer. I’ve been laying in this for, like, eight or nine hours.’”

The nurse in charge of his care told Dr. Moreno she simply hadn’t had time to help this patient yet. “She said, ‘I’ve had so many patients to take care of, and so many critical patients. I started [an IV] drip on this person. This person is on a cardiac monitor. I just didn’t have time to get in there.’”

“This is not humane care,” Dr. Moreno said. “This is horrible care.”

But it’s what can happen when emergency department staffers don’t have the resources they need to deal with the onslaught of competing demands.

“All the nurses and doctors had the highest level of intent to do the right thing for the person,” Dr. Moreno said. “But because of the high acuity of … a large number of patients, the staffing ratio of nurse to patient, even the staffing ratio of doctor to patient, this guy did not get the care that he deserved to get, just as a human being.”

The instance of unintended neglect that Dr. Moreno saw is extreme, and not the experience of most patients who arrive at ERs these days. But the problem is not new: Even before the pandemic, ER overcrowding had been a “widespread problem and a source of patient harm, according to a recent commentary in NEJM Catalyst Innovations in Care Delivery.

“ED crowding is not an issue of inconvenience,” the authors wrote. “There is incontrovertible evidence that ED crowding leads to significant patient harm, including morbidity and mortality related to consequential delays of treatment for both high- and low-acuity patients.”

And already-overwhelmed staffers are burning out.

Burnout feeds staffing shortages, and vice versa

Every morning, Tiffani Dusang wakes up and checks her Sparrow email with one singular hope: that she will not see yet another nurse resignation letter in her inbox.

“I cannot tell you how many of them [the nurses] tell me they went home crying” after their shifts, she said.

Despite Ms. Dusang’s best efforts to support her staffers, they’re leaving too fast to be replaced, either to take higher-paying gigs as a travel nurse, to try a less-stressful type of nursing, or simply walking away from the profession entirely.

Kelly Spitz has been an emergency department nurse at Sparrow for 10 years. But, lately, she has also fantasized about leaving. “It has crossed my mind several times,” she said, and yet she continues to come back. “Because I have a team here. And I love what I do.” But then she started to cry. The issue is not the hard work, or even the stress. She struggles with not being able to give her patients the kind of care and attention she wants to give them, and that they need and deserve, she said.

She often thinks about a patient whose test results revealed terminal cancer, she said. Ms. Spitz spent all day working the phones, hustling case managers, trying to get hospice care set up in the man’s home. He was going to die, and she just didn’t want him to have to die in the hospital, where only one visitor was allowed. She wanted to get him home, and back with his family.

Finally, after many hours, they found an ambulance to take him home.

Three days later, the man’s family members called Ms. Spitz: He had died surrounded by family. They were calling to thank her.

“I felt like I did my job there, because I got him home,” she said. But that’s a rare feeling these days. “I just hope it gets better. I hope it gets better soon.”

Around 4 p.m. at Sparrow Hospital as one shift approached its end, Ms. Dusang faced a new crisis: The overnight shift was more short-staffed than usual.

“Can we get two inpatient nurses?” she asked, hoping to borrow two nurses from one of the hospital floors upstairs.

“Already tried,” replied nurse Troy Latunski.

Without more staff, it’s going to be hard to care for new patients who come in overnight — from car crashes to seizures or other emergencies.

But Mr. Latunski had a plan: He would go home, snatch a few hours of sleep and return at 11 p.m. to work the overnight shift in the ER’s overflow unit. That meant he would be largely caring for eight patients, alone. On just a few short hours of sleep. But lately that seemed to be their only, and best, option.

Ms. Dusang considered for a moment, took a deep breath and nodded. “OK,” she said.

“Go home. Get some sleep. Thank you,” she added, shooting Mr. Latunski a grateful smile. And then she pivoted, because another nurse was approaching with an urgent question. On to the next crisis.

My office’s storage room has an old bankers box, which has been there since I moved 8 years ago. Before that it was at my other office, behind an old desk. I had no idea what was in it, I always assumed office supplies, surplus drug company pens and sticky notes, who-knows-whats.

Last week I had one of those days where everyone cancels, so I decided to investigate the box.

It was packed with 10 years worth (2000-2010) of my secretary’s MRI scheduling sheets that had somehow escaped occasional shredding purges. So I sat down next to the office shredder to get rid of them.

As I fed the sheets in, the names jumped out at me. Some I have absolutely no recollection of. Others I still see today.

There were names of the long-deceased, bringing them back to me for the first time in years. There were others that I have no idea what happened to – they must have just stopped seeing me at some point, though for the life of me I can’t remember when, or why. Yet, in my mind, there they were, as if I’d just seen them yesterday. A few times I got curious enough to turn back to my computer and look up their charts, trying to remember their stories.

Then there were those I still remember clearly, every single detail of, in spite of the elapsed time. Something about their case or personality had indelibly etched them in my memory. A valuable lesson learned from them that had something or nothing to do with medicine that’s still with me.

Looking back, I’d guess I’ve seen roughly 15,000-20,000 patients over my career. Not nearly as many as my colleagues in general practice, but still quite a few. A decent sized basketball arena full.

The majority don’t stick with you. That’s the way it is in life. We meet a lot of people as we walk down the road, but generally only remember those walking with us for a good part of it.

The ones we didn’t know long – but who are still clearly remembered – are also valuable. In their own way, perhaps unknowingly, they made an impact that hopefully makes us better.

For that I’ll always be grateful to them.

Women who take a wide variety of disease-modifying therapies (DMTs) for multiple sclerosis (MS) – not just those on a few types – may be especially susceptible to hair loss via alopecia, a new study finds.

From 2009 to 2019, the Food and Drug Administration received 7,978 reports of new-onset alopecia in patients taking DMTs, particularly teriflunomide (3,255, 40.8%; 90% female), dimethyl fumarate (1,641, 20.6%; 89% female), natalizumab (955, 12.0%; 92% female), and fingolimod (776, 9.7% of the total reports; 93% female), several researchers reported at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC). Of these, only teriflunomide had previously been linked to alopecia, study coauthor Ahmed Obeidat, MD, PhD, a neurologist at the Medical College of Wisconsin, Milwaukee, said in an interview.

“Our finding of frequent reports of alopecia on DMTs studied calls for further investigation into the subject,” Dr. Obeidat said. “Alopecia can cause deep personal impacts and can be a source of significant psychological concern for some patients.”

According to Dr. Obeidat, alopecia has been linked to the only a few DMTs – cladribine and the interferons – in addition to teriflunomide. “To our surprise, we received anecdotal reports of hair thinning from several of our MS patients treated with various other [DMTs]. Upon further investigation, we could not find substantial literature to explain this phenomenon which led us to conduct our investigation.”

Dr. Obeidat and colleagues identified DMT-related alopecia cases (18.3%) among 43,655 reports in the skin and subcutaneous tissue disorder category in the FDA Adverse Event Reporting System. Other DMTs with more than 1 case report were interferon beta-1a (635, 8.0%; 92% female), glatiramer acetate (332, 4.2%; 87% female), ocrelizumab (142, 1.8%; 94% female), interferon beta-1b (126, 1.6%; 95% female), alemtuzumab (86, 1.1%; 88% female), cladribine (17, 0.2%; 65% female), and rituximab (10, 0.1%; 90% female).

The average age for the case reports varied from 42 to 51 years for most of the drugs except alemtuzumab (mean age, 40 years) and cladribine (average age, 38 years), which had low numbers of cases.

Siponimod (three cases) and ozanimod (no cases) were not included in the age and gender analyses.

Why do so many women seem to be affected, well beyond their percentage of MS cases overall? The answer is unclear, said medical student Mokshal H. Porwal, the study’s lead author. “There could be a biological explanation,” Mr. Porwal said, “or women may report cases more often: “Earlier studies suggested that alopecia may affect women more adversely in terms of body image as well as overall psychological well-being, compared to males.”

The researchers also noted that patients – not medical professionals – provided most of the case reports in the FDA database. “We believe this indicates that alopecia is a patient-centered concern that may have a larger impact on their lives than what the health care teams may perceive,” Mr. Porwal said. “Oftentimes, we as health care providers, look for the more acute and apparent adverse events, which can overshadow issues such as hair thinning/alopecia that could have even greater psychological impacts on our patients.”

Dr. Obeidat said there are still multiple mysteries about DMT and alopecia risk: the true incidence of cases per DMT or DMT class, the mechanism(s) behind a link, the permanent or transient nature of the alopecia cases, and the risk factors in individual patients.

Going forward, he said, “we advise clinicians to discuss hair thinning or alopecia as a possible side effect that has been reported in association with all DMTs in the real-world, postmarketing era.”

No study funding was reported. Dr. Obeidat reported various disclosures; the other authors reported no disclosures.
