Be cautious with HBV drug withdrawal
More than half of chronic hepatitis B e antigen–negative patients who withdraw from nucleoside or nucleotide analogue therapy experienced relapse within 4 years, according to a new study that looked at patients from 11 centers in Europe, North America, and Asia.
“We wanted to see if the patients stabilize after that year. Are they just having relapses within the first year, and then they’re inactive carriers? Especially patients who don’t achieve [hepatitis B surface antigen; HBsAg] loss. Is that mildly active disease? Would they have been better off being retreated, or are they better off [staying off] therapy? It is important to look at what happens among these patients who stop and if there is a way to tell which way they’re going to go,” said Grishma Hirode, who is a PhD candidate at the University of Toronto. Ms. Hirode presented the multinational study at the annual meeting of the American Association for the Study of Liver Diseases.
The study provided a clear picture: “They do not stabilize after 1 year. They have relapses, and these relapses aren’t mild fluctuations,” said Ms. Hirode. Another study, which was presented during the same session and investigated a national cohort in Taiwan, also found a high rate of flareups and retreatment out to 4 years.
The RETRACT-B study presented by Ms. Hirode collected data on 945 patients from 11 centers in North America, Europe, and Asia. Overall, 66% had at least one relapse within 1 year of drug withdrawal. At 2 years, 40% had a sustained remission without HBsAg loss, as had 20% at 4 years; 44% had sustained remission or HBsAg loss at 2 years, as did 30% at 4 years.
Subgroup analyses found differences between some populations: 48% of Whites and 28% of Asians had sustained remission or HBsAg loss, and 30% of Whites and 20% of Asians had sustained remission without HBsAg loss. Patients who were HBsAg positive at start of therapy were more likely to have a sustained remission or HBsAg loss (36% vs. 28%; P < .05) and to have a sustained remission without HBsAg loss (31% vs. 19%; P < .05). HBsAg levels below 100 IU/mL at cessation was also associated with a greater chance of sustained remission or HBsAg loss (58% vs. 24%; P < .05) and sustained remission without HBsAg loss (24% vs. 20%; P < .05). Not having a relapse within the first year after cessation was also associated with greater chance of sustained remission or HBsAg loss (50% versus 19%; P < .05) and sustained remission without HBsAg loss (37% vs. 13%; P < .05).
The Taiwan cohort study examined the repercussions of a government policy that limited reimbursement of nucleotide/nucleoside analogues to a fixed duration of time. Among 10,192 eligible patients, researchers at I-SHOU University found a 6.58% 4-year cumulative incidence of severe flare-ups after discontinuation (95% confidence interval, 5.91%-7.30%), defined as serum ALT levels higher than five times the upper limit of normal plus serum bilirubin levels above 2 mg/dL.
The overall incidence of flare-ups was 30.66% over 4 years (95% CI, 29.37%-31.96%). Higher risk of flareup was associated with older age (hazard ratio for each 10 years, 1.19; P<.0001), male sex (HR, 1.76; P < .0001), a diagnosis of cirrhosis (HR, 1.84; P < .0001), and a history of hepatic decompensation (HR, 1.45; P = .044).
The 4-year incidence of retreatment was 48.74% (95% CI, 46.55-50.90%)
The mortality rate was 0.63% at 4 years after a flareup (95% CI, 0.44-0.87%), and the combined rate of mortality or liver transplant was 0.79% (95% CI, 0.58-1.05%). Risk factors for higher mortality included older age (per 10 years; HR, 1.70; P < .0001), a diagnosis of cirrhosis (HR, 6.12; P < .0001), and hypertension (HR, 2.29; P = .029).
Selecting patients safely?
The results of both studies suggest that withdrawal from medication should be done cautiously, and patients monitored for relapse and retreatment, according to Anna Lok, MD, who was asked for comment. Dr. Lok is a professor of internal medicine, director of clinical hematology, and assistant dean for clinical research at the University of Michigan, Ann Arbor.
Between the two studies, “the message is that this approach can benefit some patients, but if the goal of treatment withdrawal is to increase the rate of hepatitis B surface antigen loss, only a small percentage of patients would benefit. Contrary to studies in Europe, the rates of HBsAg loss in studies with predominantly Asian patients are much lower,” said Dr. Lok.
The new studies provide guidance as for which patients might safely stop treatment; specifically, she suggested, young White patients who have a low HBsAg level when treatment is stopped. “But you probably shouldn’t be trying it in older Asian patients who still have high HBsAg titer, because the chance of them relapsing is very high and the chance of benefit is very low,” she said.
“One has to be very careful in selecting which patients you’re going to try this on. And if you do want to try, you’ve got to make sure that you monitor patients very carefully so treatment can be promptly resumed if necessary because some of the patients can have a severe flare and they can even develop liver failure, and this should never be tried in patients with cirrhosis” said Dr. Lok.

Virtual center boosts liver transplant listings in rural area
A “virtual” liver transplant center servicing Vermont and New Hampshire has improved access to liver transplant listing among patients in rural areas of the region, according to a new analysis.
The virtual center was established in 2016 at Dartmouth Hitchcock Medical Center, and it allows patients to receive pre–liver transplant evaluations, testing, and care and posttransplant follow-up there rather than at the liver transplant center that conducts the surgery. The center includes two hepatologists, two associate care providers, and a nurse liver transplant coordinator at DHMC, and led to increased transplant listing in the vicinity, according to Margaret Liu, MD, who presented the study at the virtual annual meeting of the American Association for the Study of Liver Diseases.
“The initiation of this Virtual Liver Transplant Center has been able to provide patients with the ability to get a full liver transplant workup and evaluation at a center near their home rather than the often time-consuming and costly process of potentially multiple trips to a liver transplant center up to 250 miles away for a full transplant evaluation,” said Dr. Liu in an interview. Dr. Liu is an internal medicine resident at Dartmouth Hitchcock Medical Center.
“Our results did show that the initiation of a virtual liver transplant center correlated with an increased and sustained liver transplant listing rate within 60 miles of Dartmouth over that particular study period. Conversely there was no significant change in the listing rate of New Hampshire zip codes that were within 60 miles of the nearest transplant center during the same study period,” said Dr. Liu.
The center receives referrals of patients who are potential candidates for liver transplant listing from practices throughout New Hampshire and Vermont, or from their own center. Their specialists conduct full testing, including a full liver transplant workup that includes evaluation of the patient’s general health and social factors, prior to sending the patient to the actual liver transplant center for their evaluation and transplant surgery. “We essentially do all of the pre–liver transplant workup, a formal liver transplant evaluation, and then the whole packet gets sent to an actual liver transplant center to expedite the process of getting listed for liver transplant. We’re able to streamline the process, so they get everything done here at a hospital near their home. If that requires multiple trips, it’s a lot more doable for the patients,” said Dr. Liu.
The researchers defined urban areas as having more than 50,000 people per square mile and within 30 miles of the nearest hospital, and rural as fewer than 10,000 and more than 60 miles from the nearest hospital. They used the Scientific Registry of Transplant Recipients to determine the number of liver transplant listings per zip code.
Between 2015 and 2019, the frequency of liver transplant listings per 10,000 people remained nearly unchanged in the metropolitan area of southern New Hampshire, ranging from around 0.36 to 0.75. In the rural area within 60 miles of DHMC, the frequency increased from about 0.7 per 10,000 in 2015 to about 1.4 in 2016 and 0.9 in 2017. There was an increase to nearly 3 in 10,000 in 2018, and the frequency was just over 2 in 2019.
The model has the potential to be used in other areas, according to Dr. Liu. “This could potentially be implemented in other rural areas that do not have a transplant center or don’t have a formal liver transplant evaluation process,” said Dr. Liu.
While other centers may have taken on some aspects of liver transplant evaluation and posttransplant care, the Virtual Liver Transplant Center is unique in that a great deal of effort has gone into covering all of a patient’s needs for the liver transplant evaluation. “It’s really the formalization that, from what I have researched, has not been done before,” said Dr. Liu.
The model addresses transplant-listing disparity, as well as improves patient quality of life through reduction in travel, according to Mayur Brahmania, MD, of Western University, London, Ont., who moderated the session. “They’ve proven that they can get more of their patients listed over the study period, which I think is amazing. The next step, I think, would be about whether getting them onto the transplant list actually made a difference in terms of outcome – looking at their wait list mortality, looking at how many of these patients actually got a liver transplantation. That’s the ultimate outcome,” said Dr. Brahmania.
He also noted the challenge of setting up a virtual center. “You have to have allied health staff – addiction counselors, physical therapists, dietitians, social workers. You need to have the appropriate ancillary services like cardiac testing, pulmonary function testing. It’s quite an endeavor, and if the program isn’t too enthusiastic or doesn’t have a local champion, it’s really hard to get something like this started off. So kudos to them for taking on this challenge and getting this up and running over the last 5 years,” said Dr. Brahmania.

FROM THE LIVER MEETING
Opioids for headache?
Some believe that the medications, though risky, can be a useful tool in the neurologist’s treatment arsenal, while others argue that opioids are just too risky when there are other, safer alternatives available.
Those were the cruxes of arguments put forward by Paul Rizzoli, MD, and Christopher H. Gottschalk, MD, who conducted individual talks at the 2021 Scottsdale Headache Symposium. Dr. Rizzoli, associate professor of neurology at Harvard Medical School, Boston, argued in favor of the use of opioids and butalbital-containing medications. Dr. Gottschalk, assistant professor of neurology at Yale University, New Haven, Conn., argued against their use.
In certain situations opioids are worth the risk
Whether or not to use opioids in the treatment of headache is “a reasonable question, because these medications can clearly be seen as having risk. So perhaps another way to frame this question is as a risk-benefit issue. Are these medications worth the risk? How useful is the benefit of opioids, if the consequence is dependence or addiction?” Dr. Rizzoli began.
Although reviews show effectiveness of opioids in treating migraine, a three-part review in 2012 found greater efficacy of dihydroergotamine (DHE), ketorolac, and chlorpromazine. That’s not surprising, said Dr. Rizzoli, since those competing drugs are migraine-specific.
Dr. Rizzoli quoted a 2014 review indicating that there were incomplete data on the relative efficacy of opioids versus other analgesics, and for some patients opioids would likely be the optimal treatment, such as those who have contraindications to ergot-type medications or neuroleptic medications, pregnant women, or patients who don’t respond to other medications.
Dr. Rizzoli noted that The International Association for the Study of Pain has concluded that no other oral medications provide immediate and effective pain relief, and that short-term use rarely leads to addiction.
“So, to me, the answer is not to avoid opioids or outlaw them but instead to use them judiciously and infrequently, and in a short term or rescue fashion,” said Dr. Rizzoli.
He pointed out that physicians accept risks of other medications, and act to mitigate those risks. He said that risk mitigation with opioids can take the form of avoiding prescriptions in some situations, like when patients have a personal or family history of substance abuse, or in cases of some behavioral or emotional disorders.
Dr. Rizzoli went on to discuss the use of butalbital, which acts as a CNS depressant and has a variety of effects, including sedation, anxiolytic, hypnotic, and antiepileptic effects, but it is only a weak analgesic, but it nevertheless works in headache, said Dr. Rizzoli, citing patient reports and personal experience.
“It’s difficult to appreciate this theme of efficacy behind all the hype in the literature and in the press against butalbital, and the fact that it has not been adequately studied. But I would submit that the fact that we are even having this discussion is support enough for the use of butalbital. If butalbital either didn’t work or was simply a drug of abuse, it would likely have faded away by now,” said Dr. Rizzoli. He conceded that butalbital can be overused and may lead episodic headache to become chronic daily headache, but he noted that Seymour Solomon, MD, professor emeritus at Albert Einstein College of Medicine, New York, has estimated that removal of butalbital from the market would reduce chronic headache in the general population by only a small fraction of one percent.
Butalbital also has another interesting effect, which is that patients may quickly return to normal functioning after the headache resolves. “Maybe this is all due to management of anxiety, the presumed mechanism of action of barbiturates. So, instead of lobbying for its removal, I would propose that we should take a closer look at what’s going on here, and what the mechanism of action of this fairly interesting compound might be,” said Dr. Rizzoli.
Dr. Rizzoli also said there is some evidence that migraine-specific drugs also affect the tolerance to opioid drugs. “Somehow, they seem to interact with the opioid pain system. If that’s true, the implication is that you probably cannot escape the opioid receptors in the management of migraine,” said Dr. Rizzoli.
Ultimately, he supports the judicious use of opioids and butalbital containing-medications for headache relief. “My argument is that it is just too simplistic to cease use of these meds. Yes, they should be used in a restricted and careful way, but not abandoned,” said Dr. Rizzoli.
Opiates should be avoided
Following Dr. Rizzoli’s presentation, Dr. Gottschalk presented an argument against the use of opioids in the treatment of headache.
He began by quoting the ABIM Choosing Wisely Campaign of 2012, which concluded that fioricet and narcotics should be avoided in headache unless the patient is desperate. “As a headache specialist, I can tell you that I have not faced situations sufficiently desperate to use any of these. The American Headache Society in a series of evidence assessments has concluded similarly, that they are of no use,” said Dr. Gottschalk.
Opiates and barbiturates may also increase risk of migraine chronification. One study found that triptans are associated with low rates of chronification, at just a few percent when used fewer than 4 days a month, and about 20% per year when used 10-14 days per month. Opiate use showed a broadly similar pattern, while barbiturates showed a particularly alarming pattern: “Every level of use was associated with astronomically high rates and measurably higher at the highest level of use. For opiates, the odds ratio was about 2 – statistically significant. For barbiturates it was clearly greater than 2, whereas with triptans, the odds ratio showed a nonsignificant, slight increase in risk. And for NSAIDs, the odds ratio was, if anything, less than 1,” said Dr. Gottschalk.
He also discussed aspects of behavioral pharmacology, in which positive reinforcement associated with decreased headache may encourage repeated use of the drug. “Given these, it should be no surprise to anyone that emergency room treatment with opiates for acute migraine is clearly associated with increased recidivism for patients given those drugs,” said Dr. Gottschalk.
Opiate use is associated with increased pain sensitivity, and in the case of migraine, it may interfere with the activity of other treatments.
As for butalbital-containing compounds, they are positive-reinforcing drugs, and they are not indicated for migraine, only tension headache. There is no evidence of benefit in migraine, but butalbital is anxiolytic, which could lead an individual to increase its use.
A recent meta-analysis of therapies for episodic migraine found that hydromorphone and meperidine are less effective than standard therapies such as prochlorperazine or metoclopramide. Another study suggested that opioid use may interfere with the efficacy of NSAIDs in the emergency room environment, while a post hoc analysis of rizatriptan clinical trials found that recent opiate use was associated with a lower response rate, and the effect was more pronounced in women.
Among patients with chronic migraine, a 2004 study found that opiates were the most commonly used medication, and other studies found that chronic migraine does not arise in nonmigraine patients treated with opiates, “suggesting that migraine is specifically prone to opiate-induced hyperalgesia of migraine itself,” said Dr. Gottschalk.
Even under careful monitoring, misuse occurs in more than 50% of patients, “suggesting that even under the best circumstances, it is difficult to use this class of drugs safely in long term,” said Dr. Gottschalk.
He pointed out that the risk of drug addiction rises with various clinical and socioeconomic factors, including living in impoverished environments, adverse childhood experiences, low socioeconomic status, exposure to pollutants, and stressors. “In other words, all features associated with systemic racism are clearly associated with an increased risk of addiction,” said Dr. Gottschalk. Other factors include availability of the drug, such as whether or not a physician prescribes it, and repeated use.
These concerns, combined with positive-reinforcing properties of opiates and association with migraine progression and refractoriness, and the lack of progression risk found with use of NSAIDs and triptans, and the fact that effective acute therapy is associated with a lower risk of progression, argue against the use of opiates, said Dr. Gottschalk.
There is even a potential risk that the experience of migraine and its relief due to self-administration may become a rewarding experience that propagates the problem. It’s possible that anticipatory anxiety related to fear stressors could lead to migraine, or to physical sensations interpreted as migraine prodrome. “[It] raises the question of whether or not positive reinforcement by drugs makes migraine itself a rewarding experience and therefore more likely to occur as a cue for drug self-administration. The question I pose is: Is there any reason to test this theory in drugs of no proven benefit in the treatment of migraine? I would say very clearly, No,” said Dr. Gottschalk.
Clarifying the finer points of the debate
In the Q&A session after the talk, Dr. Rizzoli said that he doesn’t advocate for long-term use of opiates, except in rare cases where the diagnosis gets changed to a chronic pain syndrome. “We’re talking about intermittent use for treatment of an acute event. Do we put limits on them? I think the answer is clearly Yes, and the limits are more strict than those for triptans. My own sense as a clinician is I want all of the available tools. From a clinical perspective, there are a large number of people who do just fine with intermittent use of these medicines, and so I wouldn’t restrict them,” said Dr. Rizzoli.
Dr. Gottschalk agreed that opiates may make sense for some patients, but expressed concerns about any and all physicians prescribing them. “The part about the tools is partly a question of: Who gets to use them? In the hands of a headache specialist in those isolated cases with careful restrictions, sure. But what I’m making is a slippery slope argument: What we know is that in emergency rooms, these are used routinely, and that [those] patients are precisely the ones who are at higher risk of addiction. So in some sense, I’m just saying I think we need to have much clearer boundaries,” he said.
Dr. Rizzoli has no relevant financial disclosures. Dr. Gottschalk has been on the advisory boards of Alder, AbbVie, Amgen/Novartis, Biohaven, Theranica, Upsher-Smith, Axsome, Vorso, Currax, and Impel. He has been a consultant for Alder, Alexion, and Spherix Global Insights. He has received research support from Relivion.
Some believe that the medications, though risky, can be a useful tool in the neurologist’s treatment arsenal, while others argue that opioids are just too risky when there are other, safer alternatives available.
Those were the cruxes of arguments put forward by Paul Rizzoli, MD, and Christopher H. Gottschalk, MD, who conducted individual talks at the 2021 Scottsdale Headache Symposium. Dr. Rizzoli, associate professor of neurology at Harvard Medical School, Boston, argued in favor of the use of opioids and butalbital-containing medications. Dr. Gottschalk, assistant professor of neurology at Yale University, New Haven, Conn., argued against their use.
In certain situations opioids are worth the risk
Whether or not to use opioids in the treatment of headache is “a reasonable question, because these medications can clearly be seen as having risk. So perhaps another way to frame this question is as a risk-benefit issue. Are these medications worth the risk? How useful is the benefit of opioids, if the consequence is dependence or addiction?” Dr. Rizzoli began.
Although reviews show effectiveness of opioids in treating migraine, a three-part review in 2012 found greater efficacy of dihydroergotamine (DHE), ketorolac, and chlorpromazine. That’s not surprising, said Dr. Rizzoli, since those competing drugs are migraine-specific.

FROM 2021 SCOTTSDALE HEADACHE SYMPOSIUM
Visual snow: Alarming and not uncommon
“This is a symptom of vision where patients describe numerous flickering dots throughout their vision. Sometimes they’ll use the term grainy or pixelated vision. Many times there’s a dynamic moving component to this. Many patients will describe this as like a TV static overlay on their vision,” Carrie Robertson, MD, said during a presentation on the topic at the 2021 Scottsdale Headache Symposium. Dr. Robertson is a neurologist at the Mayo Clinic in Rochester, Minn.
“It turns out that a little over 3% of us probably see this in our vision. So even if you haven’t seen this in the clinic yet, it’s likely that you will in the future,” said Dr. Robertson.
The first report describing visual snow appeared in 1995, among migraine patients. As of 2014 there were only 10 cases described in the literature. Although the condition was initially thought of as an unusual feature of migraine, a 2014 combined chart review and survey found that 15 of 22 patients had additional visual symptoms, such as photophobia or difficulty with night vision. Twenty of the 22 patients had comorbid migraine. Other symptoms include visual ghosts that persist after looking away from an object, as well as a higher frequency of experiencing floaters.
Symptoms aren’t restricted to the visual domain. Migraine, tinnitus, dizziness, and impaired concentration also occur.
The condition is more common than many suspect. “We used to think it was very rare. Now we assume that this was just under recognized,” said Dr. Robertson. One survey in the United Kingdom found that 3.7% of respondents reported visual snow, and 2.2% met the criteria for the syndrome.
A common and typically benign problem
It is a common clinical problem, according to Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program. “Almost every week I personally see somebody and then in our group, we have a whole host of them,” he said.
“When you see these patients in clinic, it’s important to remember that this is a heterogeneous disorder,” said Dr. Robertson. “Some patients will say, ‘Oh yeah, I’ve seen visual snow for as long as I can remember, I didn’t even know it was abnormal.’ Some will describe a family history of visual snow. Others will show up in clinic panicked because their visual snow just started or sometimes it’ll start after a triggering events like a head injury or hallucinogen use, and they’re worried that they’re going to go blind.”
It’s important to rule out other potential causes. Dr. Robertson’s group examined 248 cases of visual snow and found that 89 had a comorbidity that explained the condition. Issues within the retina, cornea, and the optical nerve can cause visual snow, which makes it critical that patients be seen by an ophthalmologist.
Some patients reported improvement when they stopped a new medication. “I always ask if there was a specific medicine that they started at the onset of their symptoms,” said Dr. Robertson. Other rare conditions associated with visual snow include idiopathic intracranial hypertension, posterior cortical atrophy, and even the Heidenhain variant of Creutzfeldt-Jakob disease.
In the absence of a secondary cause, and the if condition doesn’t worsen, physicians should reassure patients that the condition is typically benign. “Many of these patients are panicked that they’re going to lose their vision, and that’s what brings them to your office. It’s important to stress that visual snow is real, that you believe them, that they’re seeing what they say that they’re seeing. It’s not a migraine aura, but it’s typically benign. I like to give the analogy that it’s similar to tinnitus because I think that that’s helpful for patients to put it in that category of benign but very annoying,” said Dr. Robertson.
Limited treatment options
Unfortunately, there is little evidence on medications to treat the problem. According to Dr. Robertson, the best available evidence – from case reports – is for lamotrigine. Nearly 20% of patients achieve a partial response, and complete responses are rare.
Clinical trials are a possibility, but patients should be made aware that medications have the potential to worsen visual snow.
Nonpharmaceutical approaches include visual and mental distraction, along with manipulation of lighting at work and at home. Stress reduction may help, and Dr. Robertson may send patients with dizziness for visual vestibular therapy to work on visual motion desensitization exercises.
There are visual snow relief videos available on YouTube, which may provide temporary relief. “It’s probably similar to white noise therapy for tinnitus,” said Dr. Robertson.
Colored glass lenses may be helpful. “I’m having the best success at this point with FL-41 lenses. Some prefer amber, and others prefer the rose-tinted, just like migraine. I usually start with that,” said Dr. Robertson. Yellow lenses may help with nyctalopia.
She recommends that patients avoid consuming too much caffeine, and that they avoid stimulants, especially attention-deficit disorder (ADD) medications. “I’ve had a lot of patients worsen with ADD medication,” said Dr. Robertson. She also warns patients away from marijuana and hallucinogens.
There is a large community available for patients with visual snow, including more than 60 Facebook groups, and many YouTube videos of patients describing their experiences. There is even a visual snow simulator that neurologists can show patients to confirm what they are seeing. “It’s very validating for the patient,” said Dr. Robertson.
Dr. Charles noted the relatively few treatment options and poor understanding of the mechanisms behind the condition. “It’s incredibly frustrating that we have to tell them that we have so little understanding of basic mechanisms, and no really clear therapeutic strategy that we can apply across all patients and expect results,” said Dr. Charles.
The heightened interest in the condition does represent some hope. “It’s very much reassuring to people that, number one, we’re starting to understand it – but number two, that they’re not crazy. It’s very much validating to hear that it’s now a topic of much more rigorous investigation,” said Dr. Charles.

“This is a symptom of vision where patients describe numerous flickering dots throughout their vision. Sometimes they’ll use the term grainy or pixelated vision. Many times there’s a dynamic moving component to this. Many patients will describe this as like a TV static overlay on their vision,” Carrie Robertson, MD, said during a presentation on the topic at the 2021 Scottsdale Headache Symposium. Dr. Robertson is a neurologist at the Mayo Clinic in Rochester, Minn.
“It turns out that a little over 3% of us probably see this in our vision. So even if you haven’t seen this in the clinic yet, it’s likely that you will in the future,” said Dr. Robertson.
The first report describing visual snow appeared in 1995, among migraine patients. As of 2014 there were only 10 cases described in the literature. Although the condition was initially thought of as an unusual feature of migraine, a 2014 combined chart review and survey found that 15 of 22 patients had additional visual symptoms, such as photophobia or difficulty with night vision. Twenty of the 22 patients had comorbid migraine. Other symptoms include visual ghosts that persist after looking away from an object, as well as a higher frequency of experiencing floaters.
Symptoms aren’t restricted to the visual domain. Migraine, tinnitus, dizziness, and impaired concentration also occur.
The condition is more common than many suspect. “We used to think it was very rare. Now we assume that this was just under recognized,” said Dr. Robertson. One survey in the United Kingdom found that 3.7% of respondents reported visual snow, and 2.2% met the criteria for the syndrome.
A common and typically benign problem
It is a common clinical problem, according to Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program. “Almost every week I personally see somebody and then in our group, we have a whole host of them,” he said.
“When you see these patients in clinic, it’s important to remember that this is a heterogeneous disorder,” said Dr. Robertson. “Some patients will say, ‘Oh yeah, I’ve seen visual snow for as long as I can remember, I didn’t even know it was abnormal.’ Some will describe a family history of visual snow. Others will show up in clinic panicked because their visual snow just started or sometimes it’ll start after a triggering events like a head injury or hallucinogen use, and they’re worried that they’re going to go blind.”
It’s important to rule out other potential causes. Dr. Robertson’s group examined 248 cases of visual snow and found that 89 had a comorbidity that explained the condition. Issues within the retina, cornea, and the optical nerve can cause visual snow, which makes it critical that patients be seen by an ophthalmologist.
Some patients reported improvement when they stopped a new medication. “I always ask if there was a specific medicine that they started at the onset of their symptoms,” said Dr. Robertson. Other rare conditions associated with visual snow include idiopathic intracranial hypertension, posterior cortical atrophy, and even the Heidenhain variant of Creutzfeldt-Jakob disease.
In the absence of a secondary cause, and the if condition doesn’t worsen, physicians should reassure patients that the condition is typically benign. “Many of these patients are panicked that they’re going to lose their vision, and that’s what brings them to your office. It’s important to stress that visual snow is real, that you believe them, that they’re seeing what they say that they’re seeing. It’s not a migraine aura, but it’s typically benign. I like to give the analogy that it’s similar to tinnitus because I think that that’s helpful for patients to put it in that category of benign but very annoying,” said Dr. Robertson.
Limited treatment options
Unfortunately, there is little evidence on medications to treat the problem. According to Dr. Robertson, the best available evidence – from case reports – is for lamotrigine. Nearly 20% of patients achieve a partial response, and complete responses are rare.
Clinical trials are a possibility, but patients should be made aware that medications have the potential to worsen visual snow.
Nonpharmaceutical approaches include visual and mental distraction, along with manipulation of lighting at work and at home. Stress reduction may help, and Dr. Robertson may send patients with dizziness for visual vestibular therapy to work on visual motion desensitization exercises.
There are visual snow relief videos available on YouTube, which may provide temporary relief. “It’s probably similar to white noise therapy for tinnitus,” said Dr. Robertson.
Colored glass lenses may be helpful. “I’m having the best success at this point with FL-41 lenses. Some prefer amber, and others prefer the rose-tinted, just like migraine. I usually start with that,” said Dr. Robertson. Yellow lenses may help with nyctalopia.

FROM 2021 SCOTTSDALE HEADACHE SYMPOSIUM
Headache is a common post–COVID-19 complaint
The Centers for Disease Control and Prevention has identified it as a sentinel symptom of COVID-19 disease. “A lot of the recommendations surrounding post-COVID headache is that if you identify a patient who has headaches associated with fever, and myalgia, and other systemic symptoms, the specificity of a COVID-19 diagnosis goes up. So [COVID-19] is a really important feature to look out for in patients with headache,” Deena Kuruvilla, MD, said during a presentation on post–COVID-19 headache at the 2021 Scottsdale Headache Symposium.
Estimates of the prevalence of headache in COVID-19 range widely, from 6.5% to 71%, but Dr. Kuruvilla has plenty of personal experience with it. “During my stint on the inpatient neurology service during the peak of COVID, I saw patients with headache being one of the most frequent complaints, [along with] dizziness, stroke, and seizure among many other neurological manifestations,” said Dr. Kuruvilla, director of the Westport (Conn.) Headache Institute.
One meta-analysis showed that 47% of patients with COVID-19 complain of headache within 30 days of diagnosis, and this drops to around 10% at 60-90 days, and around 8% at 180 days.
A survey of 3,458 patients, published in the Journal of Headache Pain, found that migraine is the most common type of post–COVID-19 headache phenotype, and patients reporting anosmia-ageusia were more likely to have post–COVID-19 headache (odds ratio [OR], 5.39; 95% confidence interval, 1.66-17.45).
A case-control study of post–COVID-19 headache patients with and without a history of migraine found that those with a history of migraine were more likely to have post–COVID-19 symptoms (OR, 1.70; P < .001) and fatigue (OR, 2.89; P = .008). “Interestingly, they found no difference in headache as post-COVID symptoms in people who had a history of migraine compared with people without a history of migraine,” said Dr. Kuruvilla.
Headache and COVID-19: What is the connection?
Several mechanisms have been proposed for direct invasion of the central nervous system, either via infection through the angiotensin-converting enzyme 2 (ACE-2) receptor, which is expressed in brain regions including the motor cortex, the posterior cingulate cortex, and the olfactory bulb, among other locations. Another potential mechanism is direct entry through the olfactory nerve and the associated olfactory epithelium. There are various potential mechanisms for spread among the peripheral nervous system, and the blood-brain barrier can be compromised by infection of vascular endothelial cells. According to the literature, neuronal damage seems to occur directly from viral damage rather than from the immune response, said Dr. Kuruvilla.
The virus may also gain entry to the CNS indirectly, as a result of hypoxia and metabolic disturbances, as well as dehydration and systematic inflammation. The cytokine storm associated with COVID-19 infection can activate C-reactive protein and calcitonin gene-related peptide (CGRP), which plays a key role in migraine pathology. The CGRP receptor antagonist vazegepant is being studied in a phase 2 clinical trial for the treatment of COVID-19–related lung inflammation.
Testing and treatment
“If I see patients with new headache, worsening headache from their baseline, or headache with systemic symptoms, I often consider screening them for COVID. If that screening is positive, I proceed with PCR testing. I also consider an MRI of the brain with and without gadolinium just to rule out any secondary causes for headache,” said Dr. Kuruvilla, noting that she has diagnosed patients with venous sinus thrombosis, ischemic stroke, and meningitis following COVID-19.
The existing literature suggests that lumbar puncture in patients with SARS-CoV-2 typically returns normal results, but Dr. Kuruvilla proceeds with it anyway with viral, bacterial, fungal, and autoimmune studies to rule out potential secondary causes for headache.
There are few studies on how to treat post–COVID-19 headache, and the general recommendation is that headache phenotype should drive treatment decisions.
In a case series, three patients with persistent headache following mild COVID-19 infection were treated with onabotulinumtoxinA and amitriptyline. They had daily headaches, along with post–COVID-19 symptoms including fatigue and insomnia. After treatment, each patient converted to episodic headaches.
One retrospective study of 37 patients found that a 5-day course of indomethacin 50 mg twice per day and pantoprazole 40 mg once per day was associated with a 50% or greater improvement in headache on the third day in 36 of the 37 patients. Five patients were free of pain by day 5.
A common problem
Neurologists have been involved in the treatment of COVID-19 since the beginning, and post–COVID-19 headache has added another layer. “It’s been a remarkably common clinical problem. And the fact that it’s actually reached the level of headache specialist actually shows that in some cases, it’s really quite a significant problem, in both its severity and persistence. So I think it’s a very, very significant issue,” said Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program.
Dr. Kuruvilla also discussed the question of whether neurological damage is due to direct damage from the virus, or indirect damage from an immune response. This was debated during the Q&A session following Dr. Kuruvilla’s talk, and it was pointed out that headache is a frequent side effect of the Pfizer and Moderna vaccines.
“It’s a huge open question about how much is direct invasion or damage or not even damage, but just change in function with the viral infection, as opposed to inflammation. The fact that very often the response to the vaccine is similar to what you see with COVID suggests that at least some component of it is inflammation. I wouldn’t commit to one mechanism or the other, but I’d say that it’s possible that it’s really both,” said Dr. Charles.
Dr. Kuruvilla has consulted for Cefaly, Neurolief, Theranica, Now What Media, and KX advisors. She has been on the speakers bureau for Abbvie/Allergan, Amgen/Novartis, and Lilly. She has been on advisory boards for Abbvie/Allergan, Lilly, Theranica, and Amgen/Novartis. Dr. Charles has no relevant financial disclosures.

FROM 2021 SCOTTSDALE HEADACHE SYMPOSIUM
Predicting cardiac shock mortality in the ICU
Addition of echocardiogram measurement of biventricular dysfunction improved the accuracy of prognosis among patients with cardiac shock (CS) in the cardiac intensive care unit.
In patients in the cardiac ICU with CS, biventricular dysfunction (BVD), as assessed using transthoracic echocardiography, improves clinical risk stratification when combined with the Society for Cardiovascular Angiography and Interventions shock stage.
No improvements in risk stratification was seen with patients with left or right ventricular systolic dysfunction (LVSD or RVSD) alone, according to an article published in the journal Chest.
Ventricular systolic dysfunction is commonly seen in patients who have suffered cardiac shock, most often on the left side. Although echocardiography is often performed on these patients during diagnosis, previous studies looking at ventricular dysfunction used invasive hemodynamic parameters, which made it challenging to incorporate their findings into general cardiac ICU practice.
Pinning down cardiac shock
Although treatment of acute MI and heart failure has improved greatly, particularly with the implementation of percutaneous coronary intervention (primary PCI) for ST-segment elevation MI. This has reduced the rate of future heart failure, but cardiac shock can occur before or after the procedure, with a 30-day mortality of 30%-40%. This outcome hasn’t improved in the last 20 years.
Efforts to improve cardiac shock outcomes through percutaneous mechanical circulatory support devices have been hindered by the fact that CS patients are heterogeneous, and prognosis may depend on a range of factors.
SCAI was developed as a five-stage classification system for CS to improve communication of patient status, as well as to improve differentiation among patients participation in clinical trials. It does not include measures of ventricular dysfunction.
Simple measure boosts prognosis accuracy
The new work adds an additional layer to the SCAI shock stage. “Adding echocardiography allows discrimination between levels of risk for each SCAI stage,” said David Baran, MD, who was asked for comment. Dr. Baran was the lead author on the original SCAI study and is system director of advanced heart failure at Sentara Heart Hospital, as well as a professor of medicine at Eastern Virginia Medical School, both in Norfolk.
The work also underscores the value of repeated measures of prognosis during a patient’s stay in the ICU. “If a patient is not improving, it may prompt a consideration of whether transfer or consultation with a tertiary center may be of value. Conversely, if a patient doesn’t have high-risk features and is responding to therapy, it is reassuring to have data supporting low mortality with that care plan,” said Dr. Baran.
The study may be biased, since not every patient undergoes an echocardiogram. Still, “the authors make a convincing case that biventricular dysfunction is a powerful negative marker across the spectrum of SCAI stages,” said Dr. Baran.
Echocardiography is simple and generally available, and some are even portable and used with a smartphone. But patient body size interferes with echocardiography, as can the presence of a ventilator or multiple surgical dressings. “The key advantage of echo is that it is completely noninvasive and can be brought to the patient in the ICU, unlike other testing which involves moving the patient to the testing environment,” said Dr. Baran.
The researchers analyzed data from 3,158 patients admitted to the cardiac ICU at the Mayo Clinic Hospital St. Mary’s Campus in Rochester, Minn., 51.8% of whom had acute coronary syndromes. They defined LVSD as a left ventricular ejection fraction less than 40%, and RVSD as at least moderate systolic dysfunction determined by semiquantitative measurement. BVD constituted the presence of both LVSD and RVSD. They examined the association of in-hospital mortality with these parameters combined with SCAI stage.
BVD a risk factor
Overall in-hospital mortality was 10%. A total of 22.3% of patients had LVSD and 11.8% had RVSD; 16.4% had moderate or greater BVD. There was no association between LVSD or RVSD and in-hospital mortality after adjustment for SCAI stage, but there was a significant association for BVD (adjusted hazard ratio, 1.815; P = .0023). When combined with SCAI, BVC led to an improved ability to predict hospital mortality (area under the curve, 0.784 vs. 0.766; P < .001). Adding semiquantitative RVSD and LVSD led to more improvement (AUC, 0.794; P < .01 vs. both).
RVSD was associated with higher in-hospital mortality (adjusted odds ratio, 1.421; P = .02), and there was a trend toward greater mortality with LVSD (aOR, 1.336; P = .06). There was little change when SCAI shock stage A patients were excluded (aOR, 1.840; P < .001).
Patients with BVD had greater in-hospital mortality than those without ventricular dysfunction (aOR, 1.815; P = .0023), but other between-group comparisons were not significant.
The researchers performed a classification and regression tree analysis using left ventricular ejection fraction (LVEF) and semiquantitative RVSD. It found that RVSD was a better predictor of in-hospital mortality than LVSD, and the best cutoff for LVSD was different among patients with RVSD and patients without RVSD.
Patients with mild or greater RVD and LVEF greater than 24% were considered high risk; those with borderline or low RVSD and LVEF less than 33%, or mild or greater RVSD with LVEF of at least 24%, were considered intermediate risk. Patients with borderline or no RVSD and LVEF of at least 33% were considered low risk. Hospital mortality was 22% in the high-risk group, 12.2% in the intermediate group, and 3.3% in the low-risk group (aOR vs. intermediate, 0.493; P = .0006; aOR vs. high risk, 0.357; P < .0001).

Addition of echocardiogram measurement of biventricular dysfunction improved the accuracy of prognosis among patients with cardiac shock (CS) in the cardiac intensive care unit.
In patients in the cardiac ICU with CS, biventricular dysfunction (BVD), as assessed using transthoracic echocardiography, improves clinical risk stratification when combined with the Society for Cardiovascular Angiography and Interventions shock stage.
No improvements in risk stratification was seen with patients with left or right ventricular systolic dysfunction (LVSD or RVSD) alone, according to an article published in the journal Chest.
Ventricular systolic dysfunction is commonly seen in patients who have suffered cardiac shock, most often on the left side. Although echocardiography is often performed on these patients during diagnosis, previous studies looking at ventricular dysfunction used invasive hemodynamic parameters, which made it challenging to incorporate their findings into general cardiac ICU practice.
Pinning down cardiac shock
Although treatment of acute MI and heart failure has improved greatly, particularly with the implementation of percutaneous coronary intervention (primary PCI) for ST-segment elevation MI. This has reduced the rate of future heart failure, but cardiac shock can occur before or after the procedure, with a 30-day mortality of 30%-40%. This outcome hasn’t improved in the last 20 years.
Efforts to improve cardiac shock outcomes through percutaneous mechanical circulatory support devices have been hindered by the fact that CS patients are heterogeneous, and prognosis may depend on a range of factors.
SCAI was developed as a five-stage classification system for CS to improve communication of patient status, as well as to improve differentiation among patients participation in clinical trials. It does not include measures of ventricular dysfunction.
Simple measure boosts prognosis accuracy
The new work adds an additional layer to the SCAI shock stage. “Adding echocardiography allows discrimination between levels of risk for each SCAI stage,” said David Baran, MD, who was asked for comment. Dr. Baran was the lead author on the original SCAI study and is system director of advanced heart failure at Sentara Heart Hospital, as well as a professor of medicine at Eastern Virginia Medical School, both in Norfolk.
The work also underscores the value of repeated measures of prognosis during a patient’s stay in the ICU. “If a patient is not improving, it may prompt a consideration of whether transfer or consultation with a tertiary center may be of value. Conversely, if a patient doesn’t have high-risk features and is responding to therapy, it is reassuring to have data supporting low mortality with that care plan,” said Dr. Baran.

Cirrhosis comorbidities tied to worse outcomes
Multiple comorbidities appear to worsen mortality outcomes in patients with cirrhosis: Those with compensated cirrhosis and three comorbid conditions have a mortality rate similar to patients with decompensated cirrhosis, according to a new analysis of a population-based cohort in the Dallas-Fort Worth metroplex.
“I think it’s a pretty strong message that just the presence of these chronic diseases has such a strong effect in the long run. They at least contribute to mortality to some extent. It’s really important to focus on these chronic diseases as targets early during the care that we provide to these to cirrhotic patients to make sure that we control them so that, in the long run, we can decrease the premature death and mortality in these patients,” said Mohammad Amin Fallahzadeh, MD, MPH, who presented the results at the annual meeting of the American Association for the Study of Liver Diseases.
The study included 35,361 patients with cirrhosis. The mean age of participants was 59.5 years, 41.8% were female, 29.7% were non-White, and 17.5% were Hispanic. Comorbidities were common, occurring in about 25% of patients. Forty-five percent of comorbidities were cardiovascular diseases (CVD); 28.9% of subjects had one comorbidity, 17.5% had two comorbidities, and 12.6% had three comorbidities.
A Kaplan-Meier curve showed that patients with compensated cirrhosis and no comorbidities had the highest survival over time, while decompensated patients with comorbidities had the lowest survival (P = .01). The curve showed similar survival between patients with compensated cirrhosis and three comorbidities and decompensated patients with no comorbidities.
The risk of death increased with one comorbidity (hazard ratio, 2.5; 95% confidence interval, 2.23-2.8), two comorbidities (HR, 3.27; 95% CI, 2.9-3.69), and three comorbidities (HR, 4.52; 95% CI, 3.99-5.12).
Mortality increased with the number of comorbidities in both compensated and decompensated patients; patients with hepatitis C, alcoholic liver disease, and nonalcoholic fatty liver disease; by race (White, Black, and other); and in different age groups. A stronger effect of comorbidities was seen in compensated patients (HR, 6.4 vs. 4.1), female patients (HR, 5.2 vs. 4.1), and in patients older than age 65 years (HR, 7.2 vs. 3.7 in those aged 45-64 years and 5.0 in those younger than age 45 years).
The researchers also found an apparent synergistic effect of chronic kidney disease (CKD) and CVD. Both conditions were associated with increased risk on their own, but when a patient had both CVD and CKD, mortality was higher than just the added risk of the two conditions.
The findings confirm that patients with cirrhosis and comorbidities seem to have worse quality of life and higher mortality. “I didn’t expect that it would have such a major effect, to make a compensated patient as if they are decompensated, but we definitely see that in our daily practice,” said Dr. Fallahzadeh, who is a 2nd-year internal medicine resident at Baylor University Medical Center, Dallas.
“When a hepatologist or an internist has a visit with a patient who is diagnosed with cirrhosis, they need to screen them for the other chronic diseases like diabetes, CKD, and cardiovascular disease to make sure that if they have any of these conditions, they’ll be under control, or if they need any referral for better management. For example, if they need a nephrology referral, it [should] be done as early as possible so that we can minimize the burden of these diseases in the long run for these patients. And we need to educate the patients as well about controlling these chronic problems,” said Dr. Fallahzadeh.
The findings might make researchers reconsider how to classify compensated and decompensated cirrhosis. “When we talk about decompensated liver disease, we’re talking about variceal hemorrhage, ascites, and encephalopathy. In this case, they’re saying that if you’re compensated and you [have] three of these associated medical conditions, that you could be worse off than decompensated cirrhosis. It’s really challenging the status quo and how we think about these two disease entities. They’re thought of a lot differently in terms of the mortality. That needs to be further elucidated,” said Mayur Brahmania, MD, assistant professor of medicine at Western University, London, Ont., who moderated the session.
A key limitation to the study was that the researchers did not have access to data about medication use, so it could not be determined if comorbidities were being controlled. Body mass index and most lifestyle factors were also uncontrolled.

FROM THE LIVER MEETING
In diabetes, fast-growing pancreatic cysts may be a red flag
LAS VEGAS – New results from a single center, retrospective analysis suggest that individuals with diabetes and pancreatic cysts have larger cyst sizes at diagnosis, and a faster subsequent cyst growth rate. Smoking was independently associated with faster growth rate.
Most pancreatic cancer patients were previously diagnosed with hyperglycemia and diabetes, and pancreatic cancer can cause diabetes. “This sort of dual causality raises questions as to whether or not hyperglycemia, or the new diagnosis of diabetes itself, could be a harbinger of cancer or precancer. And should these patients be more closely monitored?” David Robbins, MD, said in an interview.
Dr. Robbins, associate professor of medicine and program director in gastroenterology in the Northwell Health System, New York, presented the study at the annual meeting of the American College of Gastroenterology.
Faster growth rates of pancreatic cysts in the presence of diabetes are important because they represent a potential mark for cyst aggressiveness. “So the question really is, in the setting of diabetes, are there factors perhaps circulating in the bloodstream, or other intrinsic factors, that make these cysts more dangerous and require a different surveillance approach than someone who doesn’t have diabetes? We have (surveillance) guidelines that address the average population, but they don’t really hone in on what do you do with (individuals with diabetes),” Dr. Robbins said during the presentation.
The study could have implications for screening, said session moderator Dayna Early, MD, professor of medicine at Washington University and director of endoscopy at Barnes Jewish Hospital, both in St. Louis. “I think this is important information to guide us to look more closely at patients with diabetes who do have pancreatic cysts,” she said in an interview.
The study included 177 adults with pancreatic cysts or abnormal imaging results between 2013 and 2020. Sixty-five percent were female, and the mean age was 65.4 years; 64% were White, 10% were Black, and 8.5% were Asian. Among the participants, 24.8% were smokers and 32.2% had type 2 diabetes.
Patients with diabetes had larger cyst sizes (2.23 cm versus 2.76 cm), as well as a higher annual cyst growth rate (1.90 cm versus 1.30 cm). Cyst size and growth rate were similar between patients with controlled and uncontrolled diabetes. Smoking was associated with a larger cyst size overall (2.2 cm versus 1.81 cm), and were larger still among patients with diabetes who smoked (2.35 cm).
Seventy-one patients went on to have pathologic confirmation by endoscopic ultrasound-guided fine needle aspiration. “In the diabetic group, two developed adenocarcinoma, six of the nondiabetics developed adenocarcinoma, and there was no difference in CEA or serum CA 19-9,” Dr. Robbins said during his presentation.
Of 28 patients diagnosed with pancreatic cancer, 13 had type 2 diabetes.
Defining danger
There remains uncertainty about what cyst growth rate is most dangerous. Some guidelines recommend that individuals with new-onset or worsening diabetes and intraductal papillary mucinous neoplasm or mucinous cystic neoplasm cysts, or cysts alone that are growing faster than 3 mm per year, may be at significantly increased risk of pancreatic cancer. These guidelines recommend that they be screened with short-interval magnetic resonance imaging or endoscopic ultrasound (EUS) fine needle aspiration. However, this recommendation is conditional and is backed by a very low level of evidence.
Other reports have shown varying risks at different growth rates. “It’s not really clear at this point. And that’s why I think, while our study is small and exploratory, this is a particular area that is relatively easy to evaluate. We have huge databases of pancreatic cyst evolution, and we know that 30 million Americans have diabetes. So, the next obvious study is to do a more systematic look at that, and work towards refining and making sense of these divergent guidelines, all of which are saying the same thing but using different threshold numbers,” said Dr. Robbins.
The next step is do larger, multicenter studies in the context of other risk factors such as family history and smoking, but the current finding represents an opportunity to catch at least some pancreatic cancers earlier, according to Dr. Robbins. He suggested that individuals with diabetes who are diagnosed with a pancreatic cyst should be referred to a gastroenterologist or another specialist to track cyst growth. “That is going to miss a lot of folks who didn’t get imaging for whatever reason (and so don’t have a cyst identified), but it is an early opportunity, and it’s better than what we’re doing now.”
During the talk, Dr. Robbins said, “Given the ease, availability and low cost of diabetes screening in the general clinic population, we encourage the inclusion of HbA1c and fasting glucose in algorithms for pancreatic cyst surveillance.”
Dr. Early found the suggestion intriguing, but wasn’t ready to lend full support. “I think looking at the suggestion of possibly monitoring hemoglobin A1c levels was novel. I don’t know that we’ll necessarily adopt that as standard practice, but that’s something I think that could be looked at in the future as a way to help risk stratify whether patients need to be surveyed more frequently,” she said.

Most pancreatic cancer patients were previously diagnosed with hyperglycemia and diabetes, and pancreatic cancer can cause diabetes. “This sort of dual causality raises questions as to whether or not hyperglycemia, or the new diagnosis of diabetes itself, could be a harbinger of cancer or precancer. And should these patients be more closely monitored?” David Robbins, MD, said in an interview.
Dr. Robbins, associate professor of medicine and program director in gastroenterology in the Northwell Health System, New York, presented the study at the annual meeting of the American College of Gastroenterology.
Faster growth rates of pancreatic cysts in the presence of diabetes are important because they represent a potential mark for cyst aggressiveness. “So the question really is, in the setting of diabetes, are there factors perhaps circulating in the bloodstream, or other intrinsic factors, that make these cysts more dangerous and require a different surveillance approach than someone who doesn’t have diabetes? We have (surveillance) guidelines that address the average population, but they don’t really hone in on what do you do with (individuals with diabetes),” Dr. Robbins said during the presentation.
The study could have implications for screening, said session moderator Dayna Early, MD, professor of medicine at Washington University and director of endoscopy at Barnes Jewish Hospital, both in St. Louis. “I think this is important information to guide us to look more closely at patients with diabetes who do have pancreatic cysts,” she said in an interview.
The study included 177 adults with pancreatic cysts or abnormal imaging results between 2013 and 2020. Sixty-five percent were female, and the mean age was 65.4 years; 64% were White, 10% were Black, and 8.5% were Asian. Among the participants, 24.8% were smokers and 32.2% had type 2 diabetes.
Patients with diabetes had larger cyst sizes (2.23 cm versus 2.76 cm), as well as a higher annual cyst growth rate (1.90 cm versus 1.30 cm). Cyst size and growth rate were similar between patients with controlled and uncontrolled diabetes. Smoking was associated with a larger cyst size overall (2.2 cm versus 1.81 cm), and were larger still among patients with diabetes who smoked (2.35 cm).
Seventy-one patients went on to have pathologic confirmation by endoscopic ultrasound-guided fine needle aspiration. “In the diabetic group, two developed adenocarcinoma, six of the nondiabetics developed adenocarcinoma, and there was no difference in CEA or serum CA 19-9,” Dr. Robbins said during his presentation.
Of 28 patients diagnosed with pancreatic cancer, 13 had type 2 diabetes.
Defining danger
There remains uncertainty about what cyst growth rate is most dangerous. Some guidelines recommend that individuals with new-onset or worsening diabetes and intraductal papillary mucinous neoplasm or mucinous cystic neoplasm cysts, or cysts alone that are growing faster than 3 mm per year, may be at significantly increased risk of pancreatic cancer. These guidelines recommend that they be screened with short-interval magnetic resonance imaging or endoscopic ultrasound (EUS) fine needle aspiration. However, this recommendation is conditional and is backed by a very low level of evidence.
Other reports have shown varying risks at different growth rates. “It’s not really clear at this point. And that’s why I think, while our study is small and exploratory, this is a particular area that is relatively easy to evaluate. We have huge databases of pancreatic cyst evolution, and we know that 30 million Americans have diabetes. So, the next obvious study is to do a more systematic look at that, and work towards refining and making sense of these divergent guidelines, all of which are saying the same thing but using different threshold numbers,” said Dr. Robbins.
The next step is do larger, multicenter studies in the context of other risk factors such as family history and smoking, but the current finding represents an opportunity to catch at least some pancreatic cancers earlier, according to Dr. Robbins. He suggested that individuals with diabetes who are diagnosed with a pancreatic cyst should be referred to a gastroenterologist or another specialist to track cyst growth. “That is going to miss a lot of folks who didn’t get imaging for whatever reason (and so don’t have a cyst identified), but it is an early opportunity, and it’s better than what we’re doing now.”
During the talk, Dr. Robbins said, “Given the ease, availability and low cost of diabetes screening in the general clinic population, we encourage the inclusion of HbA1c and fasting glucose in algorithms for pancreatic cyst surveillance.”
Dr. Early found the suggestion intriguing, but wasn’t ready to lend full support. “I think looking at the suggestion of possibly monitoring hemoglobin A1c levels was novel. I don’t know that we’ll necessarily adopt that as standard practice, but that’s something I think that could be looked at in the future as a way to help risk stratify whether patients need to be surveyed more frequently,” she said.

Automated duodenoscope cleaner clears out contamination
LAS VEGAS – An automated cleaning system outperformed manual cleaning of duodenoscopes in a comparative study. The results included measurements of residual proteins and carbohydrates in all duodenoscope working channels and elevators.
The new automated cleaning system, called the MACH 1, can be added to existing reprocessing areas and is about the size of a commercial washing machine. Cleaning alone takes about 30 minutes, and clean plus high-level disinfection (HLD) takes about an hour, according to Michael O’Donnell, MD, who is a gastroenterology fellow at NYU Langone Health. “Data from prior studies of other automated endoscope reprocessors indicate that MACH 1 more consistently delivers cleaning results that meet or exceed Food and Drug Administration/AAMI (Association for the Advancement of Medical Instrumentation) guidelines,” Dr. O’Donnell said in an interview. He presented the study at the annual meeting of the American College of Gastroenterology.
Outbreaks of multidrug resistant organism (MDRO) transmission have been linked to inadequately cleaned duodenoscopes, which has led to greater attention being paid to duodenoscope reprocessing, including prewash, manual cleaning, and disinfection or sterilization, according to Dr. O’Donnell. Postmarketing surveillance by duodenoscope manufacturers Fujifilm, Olympus, and Pentax found a contamination rate of 5.4% for any high-concern organisms – far higher than the initially assumed 0.4%.
The researchers used FDA standard maximum allowed contaminant threshold of < 6.4 mcg/cm2 protein and < 2.2 mcg/cm2 carbohydrate. Sampling sites on the duodenoscopes included the elevator wire channel port when present, the biopsy port, the elevator wire channel, the instrument channel, and the elevator recess.
The study included Olympic TJF-Q180V duodenoscopes used in 48 endoscopic retrograde cholangiopancreatography (ERCP) procedures. Each instrument went through standard bedside precleaning; 21 were then cleaned manually by trained technicians following manufacturing instructions, and 27 were cleaned using the automated cleaning system.
In the manually cleaned duodenoscopes, the average level of residual protein was 4.88 mcg/cm2, versus 0.16 mcg/cm2 in the automated clean group. The average carbohydrate residues were 1.09 mcg/cm2 and 0.14 mcg/cm2, respectively. In all, 2 of the 21 manually cleaned devices had protein levels higher than the FDA threshold, versus none in the automated clean group. In addition, 3 of 21 in the manually cleaned group had higher than threshold carbohydrate levels, versus none in the automated clean group. Overall, 4 of the 27 manually cleaned devices and none of the 21 automated clean devices had protein or carbohydrate levels above FDA thresholds.
Removing variability from cleaning
The cleaning step is critical because failure to remove bioburden can reduce the efficacy of later HLD or sterilization. Cleaning is typically done manually, but the physical complexity of the duodenoscope makes it challenging to do it thoroughly. Manual cleaning is also susceptible to human error or insufficient training, and an observational study found that at least one error occurred in more than 90% of observed cleaning operations.
The MACH 1 uses turbulent flow and resultant shearing forces to clean the duodenoscope. The device is currently used at the medical device company Parametrik as part of a program that delivers clean duodenoscopes and ultrasound scopes to its customers. The service is currently available only in the New York metro area, but the company intends to expand to other cities in 2022. The company also has plans to sell the MACH 1 in the near future at prices comparable to automated endoscope reprocessors that don’t clean, according to Dr. O’Donnell.
“This is a huge issue, not only practically for patient care, but it’s very much in the public eye. As people who do ERCP, this is a question that patients will come to us with, so we want to be as diligent as possible to drive the bioburden in the scope as low as we can. At least intuitively, that makes sense,” said Patrick Young, MD, who comoderated the session and is a professor of medicine at the Uniformed Services University, Bethesda, Md.
He noted that the system has an advantage in that it can be applied to duodenoscopes already in house. Other approaches to the issue of improperly cleaned duodenoscopes include scopes that can be returned to the manufacturer for cleaning, or removable end cap to facilitate access to difficult to clean parts. And then there are disposal duodenoscopes. “If you’re throwing a scope away every time you use it, you worry about landfill issues and some of the long term effects of that,” said Dr. Young.
Perhaps the most important attribute of the automated cleaning device is that it allows the user to eliminate variation in the cleaning procedure. High-reliability organizations aspire to eliminating variability. “This will probably make it easier to be consistent across technicians – for example, maybe there’s one tech that cleans great and one tech that doesn’t. This may take some of that out of the equation and give you a more thorough cleaning regardless of circumstance or personnel working on it. So I think it’s exciting to have another option that might be less costly than buying new scopes,” said Dr. Young.

Alcohol-related liver disease severity increased during COVID-19 pandemic
LAS VEGAS – Over the course of the COVID-19 pandemic, alcohol-related liver disease has increased in severity, a finding that is likely related to higher consumption of alcohol and reduced care. The difference was notable in higher Model for End-Stage Liver Disease–sodium (MELD-Na) scores, more signs of hepatic decompensation, and higher mortality rates.
“Alcohol consumption during the COVID-19 pandemic led to increased morbidity and mortality, specifically in patients that already had underlying liver disease. The importance of alcohol cessation, counseling, and close physician monitoring is emphasized, given continued or relapsed alcohol consumption can significantly affect quality of life, life expectancy, and liver transplantation candidacy,” research team member Lindsay A. Sobotka, DO, said in an interview. Dr. Sobotka is an assistant professor of gastroenterology, hepatology, and nutrition at the Ohio State University Wexner Medical Center, Columbus.
The research was presented by Ayushi Jain, MD, at the annual meeting of the American College of Gastroenterology. Dr. Jain is a resident at the Ohio State University Wexner Medical Center.
Dr. Jain noted that alcohol sales have gone up during the pandemic, with monthly sales up 14%-44% between February and September 2020, compared with the same months in previous years.
Decompensation rates rose
The researchers analyzed data from patients with alcoholic cirrhosis or alcoholic hepatitis who were seen at the Ohio State University Medical Center between March and August 2019, and between March and August 2020.
During the pandemic, the number of hospital admissions nearly doubled among alcoholic hepatitis patients (86 to 162), but declined slightly among patients with alcoholic cirrhosis (613 to 528), possibly because of efforts to manage decompensation and avoid hospitalizations during the pandemic, according to Dr. Jain. In total, 4 of 162 patients with alcoholic hepatitis and 14 of 528 patients with alcoholic cirrhosis had COVID-19 at the time of admission.
Higher mortality rates were seen during the pandemic, although this was only significant for alcoholic cirrhosis: 14.8% versus 7% for alcoholic hepatitis (P = .06) and 13.5% versus 7.4% for alcoholic cirrhosis (P = .001).
Among those with alcoholic hepatitis, there was no significant change in median Maddrey’s Discriminant Function during the pandemic (P = .51), but the researchers noted a significant decrease in steroid use, from 27 patients to 23 (P = .001). “This may be due to a statistically significant increase in GI bleeds and renal dysfunction that we noted during the pandemic,” said Dr. Jain.
Hepatic decompensation and critical care needs increased among patients admitted with alcoholic hepatitis, including hepatic encephalopathy (P = .037), gastrointestinal bleeding (P = .01), a need for increased oxygen (P = .024), vasopressor support (P = .005), and initiation of hemodialysis (P = .007). The median highest MELD-Na score during admission was also higher during the pandemic (24 vs. 23, P = .04).
Patients with alcoholic cirrhosis had greater decompensation as measured by ascites (P = .01), therapeutic paracentesis (P = .04), titration of diuretics (P = .005), acute kidney injury (P = .005), hepatorenal syndrome (P = .002), and spontaneous bacterial peritonitis (P = .04). They also had greater need for vasopressor support (9% to 14%; P = .006), were more likely to initiate hemodialysis (7% to 11%; P = .015), and had greater mortality (7% to 14%; P = .001).
In all, 212 patients reported increased alcohol intake, 161 reported little change over the past year, and 253 said they were abstinent. MELD-Na scores were highest in the increased group (27), compared with the unchanged group (24) and abstinent group (23) (P = .001).
More robust support needed
“This highlights that the increase in alcohol use seems to be associated with higher rates of more severe alcoholic hepatitis, and we are going to need to all be aware of and intervene in these individuals, and try to not only make health care more accessible, but help those with alcohol use disorder to reengage in some support systems [and] harm-reduction measures, to try to reduce the number of these episodes of admissions with severe alcoholic hepatitis,” said Paul Kwo, MD, who comoderated the session. Dr. Kwo is a professor of medicine at Stanford (Calif.) University.
Dr. Kwo suggested that the pandemic has presented dual challenges to patients with alcohol-related liver disease. One is that hospitals have filled up because of an influx of COVID-19 cases, which makes it hard for them to compete for limited resources. The other is that lockdowns and social interruptions may have interfered with the support systems that normally help them to keep sober and maintain health care. “The pandemic really disrupted everybody’s ecosystem substantially, and some of these individuals, as their ecosystems crumble, they don’t have other resources to engage in care, and then they present with far more advanced comorbidities than we might have seen prior to the pandemic,” said Dr. Kwo.
The findings underscore at least one lesson that can be drawn from the pandemic. “We now know that we have to develop more robust systems to provide support for all of these individuals,” said Dr. Kwo.
Comoderator Patricia D. Jones, MD, agreed, and expressed optimism. “We were forced develop more remote or virtual networks, so I think there are a lot of people that are taking advantage maybe of virtual [Alcoholics Anonymous], and that wasn’t something that they necessarily did [before the pandemic]. And so at least we’ve developed some parallel systems that hopefully people will benefit from,” said Dr. Jones, who is an assistant professor of medicine at the University of Miami.
She suggested that physicians should make inquiries about patients with alcohol-related liver disease and their social situations, and might consider trying to connect them to a social worker if called for. “I think that really speaking to the person about where they are would be beneficial,” said Dr. Jones.

They also had greater need for vasopressor support (9% to 14%; P = .006), were more likely to initiate hemodialysis (7% to 11%; P = .015), and had greater mortality (7% to 14%; P = .001).
In all, 212 patients reported increased alcohol intake, 161 reported little change over the past year, and 253 said they were abstinent. MELD-Na scores were highest in the increased group (27), compared with the unchanged group (24) and abstinent group (23) (P = .001).
More robust support needed
“This highlights that the increase in alcohol use seems to be associated with higher rates of more severe alcoholic hepatitis, and we are going to need to all be aware of and intervene in these individuals, and try to not only make health care more accessible, but help those with alcohol use disorder to reengage in some support systems [and] harm-reduction measures, to try to reduce the number of these episodes of admissions with severe alcoholic hepatitis,” said Paul Kwo, MD, who comoderated the session. Dr. Kwo is a professor of medicine at Stanford (Calif.) University.
Dr. Kwo suggested that the pandemic has presented dual challenges to patients with alcohol-related liver disease. One is that hospitals have filled up because of an influx of COVID-19 cases, which makes it hard for them to compete for limited resources. The other is that lockdowns and social interruptions may have interfered with the support systems that normally help them to keep sober and maintain health care. “The pandemic really disrupted everybody’s ecosystem substantially, and some of these individuals, as their ecosystems crumble, they don’t have other resources to engage in care, and then they present with far more advanced comorbidities than we might have seen prior to the pandemic,” said Dr. Kwo.
The findings underscore at least one lesson that can be drawn from the pandemic. “We now know that we have to develop more robust systems to provide support for all of these individuals,” said Dr. Kwo.
Comoderator Patricia D. Jones, MD, agreed, and expressed optimism. “We were forced develop more remote or virtual networks, so I think there are a lot of people that are taking advantage maybe of virtual [Alcoholics Anonymous], and that wasn’t something that they necessarily did [before the pandemic]. And so at least we’ve developed some parallel systems that hopefully people will benefit from,” said Dr. Jones, who is an assistant professor of medicine at the University of Miami.
She suggested that physicians should make inquiries about patients with alcohol-related liver disease and their social situations, and might consider trying to connect them to a social worker if called for. “I think that really speaking to the person about where they are would be beneficial,” said Dr. Jones.

LAS VEGAS – Over the course of the COVID-19 pandemic, alcohol-related liver disease has increased in severity, a finding that is likely related to higher consumption of alcohol and reduced care. The difference was notable in higher Model for End-Stage Liver Disease–sodium (MELD-Na) scores, more signs of hepatic decompensation, and higher mortality rates.
“Alcohol consumption during the COVID-19 pandemic led to increased morbidity and mortality, specifically in patients that already had underlying liver disease. The importance of alcohol cessation, counseling, and close physician monitoring is emphasized, given continued or relapsed alcohol consumption can significantly affect quality of life, life expectancy, and liver transplantation candidacy,” research team member Lindsay A. Sobotka, DO, said in an interview. Dr. Sobotka is an assistant professor of gastroenterology, hepatology, and nutrition at the Ohio State University Wexner Medical Center, Columbus.
The research was presented by Ayushi Jain, MD, at the annual meeting of the American College of Gastroenterology. Dr. Jain is a resident at the Ohio State University Wexner Medical Center.
Dr. Jain noted that alcohol sales have gone up during the pandemic, with monthly sales up 14%-44% between February and September 2020, compared with the same months in previous years.
Decompensation rates rose
The researchers analyzed data from patients with alcoholic cirrhosis or alcoholic hepatitis who were seen at the Ohio State University Medical Center between March and August 2019, and between March and August 2020.
During the pandemic, the number of hospital admissions nearly doubled among alcoholic hepatitis patients (86 to 162), but declined slightly among patients with alcoholic cirrhosis (613 to 528), possibly because of efforts to manage decompensation and avoid hospitalizations during the pandemic, according to Dr. Jain. In total, 4 of 162 patients with alcoholic hepatitis and 14 of 528 patients with alcoholic cirrhosis had COVID-19 at the time of admission.
Higher mortality rates were seen during the pandemic, although this was only significant for alcoholic cirrhosis: 14.8% versus 7% for alcoholic hepatitis (P = .06) and 13.5% versus 7.4% for alcoholic cirrhosis (P = .001).
Among those with alcoholic hepatitis, there was no significant change in median Maddrey’s Discriminant Function during the pandemic (P = .51), but the researchers noted a significant decrease in steroid use, from 27 patients to 23 (P = .001). “This may be due to a statistically significant increase in GI bleeds and renal dysfunction that we noted during the pandemic,” said Dr. Jain.
Hepatic decompensation and critical care needs increased among patients admitted with alcoholic hepatitis, including hepatic encephalopathy (P = .037), gastrointestinal bleeding (P = .01), a need for increased oxygen (P = .024), vasopressor support (P = .005), and initiation of hemodialysis (P = .007). The median highest MELD-Na score during admission was also higher during the pandemic (24 vs. 23, P = .04).
Patients with alcoholic cirrhosis had greater decompensation as measured by ascites (P = .01), therapeutic paracentesis (P = .04), titration of diuretics (P = .005), acute kidney injury (P = .005), hepatorenal syndrome (P = .002), and spontaneous bacterial peritonitis (P = .04). They also had greater need for vasopressor support (9% to 14%; P = .006), were more likely to initiate hemodialysis (7% to 11%; P = .015), and had greater mortality (7% to 14%; P = .001).
In all, 212 patients reported increased alcohol intake, 161 reported little change over the past year, and 253 said they were abstinent. MELD-Na scores were highest in the increased group (27), compared with the unchanged group (24) and abstinent group (23) (P = .001).
