A smartphone app that combines passively collected physiologic data from wearable devices, such as fitness trackers, and self-reported symptoms can discriminate between COVID-19–positive and –negative individuals among those who report symptoms, new data suggest.

After analyzing data from more than 30,000 participants, researchers from the Digital Engagement and Tracking for Early Control and Treatment (DETECT) study concluded that adding individual changes in sensor data improves models based on symptoms alone for differentiating symptomatic persons who are COVID-19 positive and symptomatic persons who are COVID-19 negative.

The combination can potentially identify infection clusters before wider community spread occurs, Giorgio Quer, PhD, and colleagues report in an article published online Oct. 29 in Nature Medicine. DETECT investigators note that marrying participant-reported symptoms with personal sensor data, such as deviation from normal sleep duration and resting heart rate, resulted in an area under the curve (AUC) of 0.80 (interquartile range [IQR], 0.73-0.86) for differentiating between symptomatic individuals who were positive and those who were negative for COVID-19.

“By better characterizing each individual’s unique baseline, you can then identify changes that may indicate that someone has a viral illness,” said Dr. Quer, director of artificial intelligence at Scripps Research Translational Institute in La Jolla, Calif. “In previous research, we found that the proportion of individuals with elevated resting heart rate and sleep duration compared with their normal could significantly improve real-time detection of influenza-like illness rates at the state level,” he said in an interview.

Thus, continuous passively captured data may be a useful adjunct to bricks-and-mortar site testing, which is generally a one-off or infrequent sampling assay and is not always easily accessible, he added. Furthermore, traditional screening with temperature and symptom reporting is inadequate. An elevation in temperature is not as common as frequently believed for people who test positive for COVID-19, Dr. Quer continued. “Early identification via sensor variables of those who are presymptomatic or even asymptomatic would be especially valuable, as people may potentially be infectious during this period, and early detection is the ultimate goal,” Dr. Quer said.

According to his group, adding these physiologic changes from baseline values significantly outperformed detection (P < .01) using a British model described in an earlier study by by Cristina Menni, PhD, and associates. That method, in which symptoms were considered alone, yielded an AUC of 0.71 (IQR, 0.63-0.79).

According to Dr. Quer, one in five Americans currently wear an electronic device. “If we could enroll even a small percentage of these individuals, we’d be able to potentially identify clusters before they have the opportunity to spread,” he said.
 

DETECT study details

During the period March 15 to June 7, 2020, the study enrolled 30,529 participants from all 50 states. They ranged in age from younger than 35 years (23.1%) to older than 65 years (12.8%); the majority (63.5%) were aged 35-65 years, and 62% were women. Sensor devices in use by the cohort included Fitbit activity trackers (78.4%) and Apple HealthKit (31.2%).

Participants downloaded an app called MyDataHelps, which collects smartwatch and activity tracker information, including self-reported symptoms and diagnostic testing results. The app also monitors changes from baseline in resting heart rate, sleep duration, and physical activity, as measured by steps.

Overall, 3,811 participants reported having at least one symptom of some kind (e.g., fatigue, cough, dyspnea, loss of taste or smell). Of these, 54 reported testing positive for COVID-19, and 279 reported testing negative.

Sleep and activity were significantly different for the positive and negative groups, with an AUC of 0.68 (IQR, 0.57-0.79) for the sleep metric and 0.69 (IQR, 0.61-0.77) for the activity metric, suggesting that these parameters were more affected in COVID-19–positive participants.

When the investigators combined resting heart rate, sleep, and activity into a single metric, predictive performance improved to an AUC of 0.72 (IQR, 0.64-0.80).

The next step, Dr. Quer said, is to include an alert to notify users of possible infection.
 

Alerting users to possible COVID-19 infection

In a similar study, an alert feature was already incorporated. The study, led by Michael P. Snyder, PhD, director of the Center for Genomics and Personalized Medicine at Stanford (Calif.) University, will soon be published online in Nature Biomedical Engineering. In that study, presymptomatic detection of COVID-19 was achieved in more than 80% of participants using resting heart rate.

“The median is 4 days prior to symptom formation,” Dr. Snyder said in an interview. “We have an alarm system to notify people when their heart rate is elevated. So a positive signal from a smartwatch can be used to follow up by polymerase chain reaction [testing].”

Dr. Snyder said these approaches offer a roadmap to containing widespread infections. “Public health authorities need to be open to these technologies and begin incorporating them into their tracking,” he said. “Right now, people do temperature checks, which are of limited value. Resting heart rate is much better information.”

Although the DETECT researchers have not yet received feedback on their results, they believe public health authorities could recommend the use of such apps. “These are devices that people routinely wear for tracking their fitness and sleep, so it would be relatively easy to use the data for viral illness tracking,” said co–lead author Jennifer Radin, PhD, an epidemiologist at Scripps. “Testing resources are still limited and don’t allow for routine serial testing of individuals who may be asymptomatic or presymptomatic. Wearables can offer a different way to routinely monitor and screen people for changes in their data that may indicate COVID-19.”

The marshaling of data through consumer digital platforms to fight the coronavirus is gaining ground. New York State and New Jersey are already embracing smartphone apps to alert individuals to possible exposure to the virus.

More than 710,000 New Yorkers have downloaded the COVID NY Alert app, launched in October to help protect individuals and communities from COVID-19 by sending alerts without compromising privacy or personal information. “Upon receiving a notification about a potential exposure, users are then able to self-quarantine, get tested, and reduce the potential exposure risk to family, friends, coworkers, and others,” Jonah Bruno, a spokesperson for the New York State Department of Health, said in an interview.

And recently the Mayo Clinic and Safe Health Systems launched a platform to store COVID-19 testing and vaccination data.

Both the Scripps and Stanford platforms are part of a global technologic response to the COVID-19 pandemic. Prospective studies, led by device manufacturers and academic institutions, allow individuals to voluntarily share sensor and clinical data to address the crisis. Similar approaches have been used to track COVID-19 in large populations in Germany via the Corona Data Donation app.

The study by Dr. Quer and colleagues was funded by a grant from the National Center for Advancing Translational Sciences at the National Institutes of Health. One coauthor reported grants from Janssen and personal fees from Otsuka and Livongo outside of the submitted work. The other authors have disclosed no relevant financial relationships. Dr. Snyder has ties to Personalis, Qbio, January, SensOmics, Protos, Mirvie, and Oralome.

Black patients may be significantly less likely to receive eradication testing after treatment for Helicobacter pylori infection than patients of other races/ethnic groups, based on a retrospective analysis of more than 1,700 individuals.

This disparity may exacerbate the already increased burden of H. pylori infection and gastric cancer among Black individuals, according to principal author David A. Leiman, MD, MSHP, of Duke University Medical Center in Durham, N.C.

“H. pylori infection disproportionately affects racial/ethnic minorities and those of lower socioeconomic status,” Dr. Leiman, coauthor Julius Wilder, MD, PhD, of Duke University in Durham, and colleagues wrote in their abstract presented at the annual meeting of the American College of Gastroenterology. “ACG guidelines recommend treatment for H. pylori infection followed by confirmation of cure. Adherence to these recommendations varies and its impact on practice patterns is unclear. This study characterizes the management of H. pylori infection and predictors of guideline adherence.”

The investigators analyzed electronic medical records from 1,711 patients diagnosed with H. pylori infection through the Duke University Health System between June 2016 and June 2018, most often (71%) via serum antibody test. Approximately two-thirds of those diagnosed were non-White (66%) and female (63%). Out of 1,711 patients, 622 (36%) underwent eradication testing, of whom 559 (90%) were cured.

Despite publication of the ACG H. pylori guideline midway through the study (February 2017), testing rates dropped significantly from 43.1% in 2016 to 35.9% in 2017, and finally 25.5% in 2018 (P < .0001).

“These findings are consistent with other work that has shown low rates of testing to confirm cure in patients treated for H. pylori,” Dr. Leiman said. “There remains a disappointingly low number of patients who are tested for cure.”

Across the entire study period, patients were significantly more likely to undergo eradication testing if they were treated in the gastroenterology department (52.4%), compared with rates ranging from 33% to 34.6% for internal medicine, family medicine, and other departments (P < .001).

Across all departments, Black patients underwent eradication testing significantly less often than patients of other races/ethnicities, at a rate of 30.5% versus 32.2% for White patients, 35.1% for Asian patients, and 36.7% for patients who were of other backgrounds (P < .001). Compared with White patients, Black patients were 38% less likely to undergo eradication testing (odds ratio, 0.62; 95% confidence interval, 0.48-0.79).

Dr. Leiman noted that these findings contrast with a study by Dr. Shria Kumar and colleagues from earlier this year, which found no racial disparity in eradication testing within a Veterans Health Affairs cohort.

“Black patients are significantly less likely to undergo testing for eradication than [patients of other races/ethnicities],” Dr. Leiman said. “More work is needed to understand the mechanisms driving this disparity.” He suggested a number of possible contributing factors, including provider knowledge gaps, fragmented care, and social determinants of health.

“It is clear that a greater emphasis on characterizing and addressing the social determinants of health, including poverty, education, and location, are needed,” Dr. Leiman said. “Although health systems are not solely responsible for the known and ongoing observations of disparities in care, interventions must be identified and implemented to mitigate these issues.” Such interventions would likely require broad participation, he said, including policy makers, health systems, and individual practitioners.

“We plan to perform a prospective mixed methods study to contextualize which social determinants are associated with a decreased likelihood of receiving appropriate eradication testing by exploring barriers at patient, practitioner, and health-system levels,” Dr. Leiman said. “Ultimately, we aim to leverage these findings to develop an evidence-based intervention to circumnavigate those identified barriers, thereby eliminating the observed disparities in H. pylori care.”

According to Gregory L. Hall, MD, of Northeast Ohio Medical University, Rootstown, and Case Western Reserve University, Cleveland, and codirector of the Partnership for Urban Health Research, Atlanta, the higher rate of H. pylori infection in Black individuals may stem partly from genetic factors.

“Studies have shown that African Americans with a higher proportion of African ancestry have higher rates of H. pylori, suggesting a genetic component to this increased risk,” he said.

Still, Dr. Hall, who is the author of the book Patient-Centered Clinical Care for African Americans, went on to emphasize appropriate H. pylori management and recognition of racial disparities in medicine.

“The ability to test for, treat, and confirm eradication of H. pylori infections represents a great opportunity to improve quality of life through decreased gastritis, gastric ulcers, and gastric cancer,” he said. “[The present findings] show yet another disparity in our clinical care of African Americans that needs increased awareness among providers to these communities.”

Rotonya Carr, MD, of the Hospital of the University of Pennsylvania, Philadelphia, and lead author of a recent publication addressing racism and health disparities in gastroenterology, said the findings of the present study add weight to a known equity gap.

“These data are concerning in view of the twofold higher prevalence of H. pylori seropositivity and twofold higher incidence of gastric cancer in Black patients, compared with White patients,” Dr. Carr said. “These and other data support a comprehensive approach to reduce GI disparities that includes targeted education of both GI specialists and referring providers.”

According to Dr. Leiman, individual practitioners may work toward more equitable outcomes through a comprehensive clinical approach, regardless of patient race or ethnicity.

“Clinicians should consider H. pylori therapy an episode of care that spans diagnosis, treatment, and confirmation of cure,” he said. “Closing the loop in that episode by ensuring eradication is vital to conforming with best practices, and to reduce patients’ long-term risks.”The investigators disclosed relationships with Exact Sciences, Guardant Health, and Phathom Pharmaceuticals. Dr. Hall and Dr. Carr reported no relevant conflicts of interest.

The investigators analyzed electronic medical records from 1,711 patients diagnosed with H. pylori infection through the Duke University Health System between June 2016 and June 2018, most often (71%) via serum antibody test. Approximately two-thirds of those diagnosed were non-White (66%) and female (63%). Out of 1,711 patients, 622 (36%) underwent eradication testing, of whom 559 (90%) were cured.

Despite publication of the ACG H. pylori guideline midway through the study (February 2017), testing rates dropped significantly from 43.1% in 2016 to 35.9% in 2017, and finally 25.5% in 2018 (P < .0001).

“These findings are consistent with other work that has shown low rates of testing to confirm cure in patients treated for H. pylori,” Dr. Leiman said. “There remains a disappointingly low number of patients who are tested for cure.”

Across the entire study period, patients were significantly more likely to undergo eradication testing if they were treated in the gastroenterology department (52.4%), compared with rates ranging from 33% to 34.6% for internal medicine, family medicine, and other departments (P < .001).

Across all departments, Black patients underwent eradication testing significantly less often than patients of other races/ethnicities, at a rate of 30.5% versus 32.2% for White patients, 35.1% for Asian patients, and 36.7% for patients who were of other backgrounds (P < .001). Compared with White patients, Black patients were 38% less likely to undergo eradication testing (odds ratio, 0.62; 95% confidence interval, 0.48-0.79).

Dr. Leiman noted that these findings contrast with a study by Dr. Shria Kumar and colleagues from earlier this year, which found no racial disparity in eradication testing within a Veterans Health Affairs cohort.

“Black patients are significantly less likely to undergo testing for eradication than [patients of other races/ethnicities],” Dr. Leiman said. “More work is needed to understand the mechanisms driving this disparity.” He suggested a number of possible contributing factors, including provider knowledge gaps, fragmented care, and social determinants of health.

“It is clear that a greater emphasis on characterizing and addressing the social determinants of health, including poverty, education, and location, are needed,” Dr. Leiman said. “Although health systems are not solely responsible for the known and ongoing observations of disparities in care, interventions must be identified and implemented to mitigate these issues.” Such interventions would likely require broad participation, he said, including policy makers, health systems, and individual practitioners.

“We plan to perform a prospective mixed methods study to contextualize which social determinants are associated with a decreased likelihood of receiving appropriate eradication testing by exploring barriers at patient, practitioner, and health-system levels,” Dr. Leiman said. “Ultimately, we aim to leverage these findings to develop an evidence-based intervention to circumnavigate those identified barriers, thereby eliminating the observed disparities in H. pylori care.”

According to Gregory L. Hall, MD, of Northeast Ohio Medical University, Rootstown, and Case Western Reserve University, Cleveland, and codirector of the Partnership for Urban Health Research, Atlanta, the higher rate of H. pylori infection in Black individuals may stem partly from genetic factors.

“Studies have shown that African Americans with a higher proportion of African ancestry have higher rates of H. pylori, suggesting a genetic component to this increased risk,” he said.

Still, Dr. Hall, who is the author of the book Patient-Centered Clinical Care for African Americans, went on to emphasize appropriate H. pylori management and recognition of racial disparities in medicine.

“The ability to test for, treat, and confirm eradication of H. pylori infections represents a great opportunity to improve quality of life through decreased gastritis, gastric ulcers, and gastric cancer,” he said. “[The present findings] show yet another disparity in our clinical care of African Americans that needs increased awareness among providers to these communities.”

Rotonya Carr, MD, of the Hospital of the University of Pennsylvania, Philadelphia, and lead author of a recent publication addressing racism and health disparities in gastroenterology, said the findings of the present study add weight to a known equity gap.

“These data are concerning in view of the twofold higher prevalence of H. pylori seropositivity and twofold higher incidence of gastric cancer in Black patients, compared with White patients,” Dr. Carr said. “These and other data support a comprehensive approach to reduce GI disparities that includes targeted education of both GI specialists and referring providers.”

According to Dr. Leiman, individual practitioners may work toward more equitable outcomes through a comprehensive clinical approach, regardless of patient race or ethnicity.

“Clinicians should consider H. pylori therapy an episode of care that spans diagnosis, treatment, and confirmation of cure,” he said. “Closing the loop in that episode by ensuring eradication is vital to conforming with best practices, and to reduce patients’ long-term risks.”The investigators disclosed relationships with Exact Sciences, Guardant Health, and Phathom Pharmaceuticals. Dr. Hall and Dr. Carr reported no relevant conflicts of interest.

Editors in chief at 10 leading family medicine journals have banded together to address systemic racism in research, health care, and the medical profession.

Sumi Sexton, MD, editor in chief of American Family Physician (AFP), said in an interview she had been working on changes at her journal that would answer the need for action that was made clear by this summer’s Black Lives Matter protests and realized the issue was much bigger than one journal. She proposed the collaboration with the other editors.

The editors wrote a joint statement explaining what they plan to do collectively. It was published online Oct. 15 ahead of print and will be published in all 10 journals at the beginning of the year.

Following the action by family medicine editors, the American College of Physicians issued a statement expressing commitment to being an antiracist organization. It calls on all doctors to speak out against hate and discrimination and to act against institutional and systemic racism. The statement also apologizes for the organization’s own past actions: “ACP acknowledges and regrets its own historical organizational injustices and inequities, and past racism, discrimination and exclusionary practices throughout its history, whether intentional or unintentional, by act or omission.”


 

Family medicine journals plan changes

Changes will differ at each family medicine publication, according to Sexton and other interviewees. Some specific changes at AFP, for example, include creating a medical editor role dedicated to diversity, equity, and inclusion to ensure that content is not only accurate but also that more content addresses racism, Dr. Sexton said.

AFP is creating a Web page dedicated to diversity and will now capitalize the word “Black” in racial and cultural references. Recent calls for papers have included emphasis on finding authors from underrepresented groups and on mentoring new authors.

“We really need to enable our colleagues,” Dr. Sexton said.

The journals are also pooling their published research on topics of racism and inclusion and have established a joint bibliography.

The steps are important, Dr. Sexton said, because reform in research will start a “cascade of action” that will result in better patient care.

“Our mission is to care for the individual as a whole person,” Dr. Sexton said. “This is part of that mission.”
 

Increasing diversity on editorial boards

Family physician Kameron Leigh Matthews, MD, chief medical officer for the Veterans Health Administration, praised the journals’ plan.

She noted that the groups are addressing diversity on their editorial boards, as well as evaluating content. Effective change must also happen regarding the people reviewing the content, she said in an interview. “It has to be both.

“I’m very proud as a family physician that our editors came together and are giving the right response. It’s not enough to say we stand against racism. They’re actually offering concrete actions that they will take as editors, and that will influence health care,” she said.

Dr. Matthews pointed to an example of what can happen when the editorial process fails and racism is introduced in research.

She cited the retraction of an article in the Journal of the American Heart Association entitled, “Evolution of Race and Ethnicity Considerations for the Cardiology Workforce.” The article advocated for ending racial and ethnic preferences in undergraduate and medical school admissions.

The American Heart Association said the article concluded “incorrectly that Black and Hispanic trainees in medicine are less qualified than White and Asian trainees.” The article had “rightfully drawn criticism for its misrepresentations and conclusions,” the AHA said, adding that it would launch an investigation into how the article came to be published.

Dr. Matthews says that’s why it’s so important that, in their statement, the family medicine editors vow to address not only the content but also the editing process to avoid similar systemic lapses.

Dr. Matthews added that, because the proportion of physicians from underrepresented groups is small – only 5% of physicians are Black and 6% are Hispanic – it is vital, as recommended in the editors’ statement, to mentor researchers from underrepresented groups and to reach out to students and residents to be coauthors.

“To sit back and say there’s not enough to recruit from is not sufficient,” Dr. Matthews said. “You need to recognize that you need to assist with expanding the pool.”

She also said she would like to see the journals focus more heavily on solutions to racial disparities in health care rather than on pointing them out.

At the Journal of Family Practice (JFP), Editor in Chief John Hickner, MD, said adding diversity to the editorial board is a top priority. He also reiterated that diversity in top leadership is a concern across all the journals, inasmuch as only 1 of the 10 editors in chief is a person of color.

As an editor, he said, he will personally, as well as through family medicine department chairs, be seeking authors who are members of underrepresented groups and that he will be assisting those who need help.

“I’m committed to giving them special attention in the editorial process,” he said.

Dr. Hickner said the 10 journals have also committed to periodically evaluate whether their approaches are making substantial changes. He said the editors have vowed to meet at least once a year to review progress “and hold each other accountable.”

Statement authors, in addition to Dr. Sexton and Dr. Hickner, include these editors in chief: Caroline R. Richardson, MD, Annals of Family Medicine; Sarina B. Schrager, MD, FPM; Marjorie A. Bowman, MD, The Journal of the American Board of Family Medicine; Christopher P. Morley, PhD, PRiMER; Nicholas Pimlott, MD, PhD, Canadian Family Physician; John W. Saultz, MD, Family Medicine; and Barry D. Weiss, MD, FP Essentials.

The authors have disclosed no relevant financial relationships. The Journal of Family Practice is owned by the same news organization as this publication.

When selecting pharmacotherapy for patients with bipolar disorder, clinical and prognostic correlates will ultimately influence what treatments make the most sense for a patient – but the process is a balancing act, according to Joseph F. Goldberg, MD.

“Everything we do in medicine in general, and psychiatry, and bipolar disorder in particular is a risk-benefit analysis,” Dr. Goldberg said at the virtual Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “Everything has its side effects. We’re always balancing risks and benefits.”

Patients with bipolar disorder often present with three common subtypes of the illness: Those who have associated psychosis, comorbid anxiety disorders, and comorbid ADHD. “These are three common presentations of the many, many kinds of presentations,” said Dr. Goldberg, clinical professor of psychiatry at the Icahn School of Medicine at Mount Sinai in New York.

Bipolar disorder with associated psychosis

In the case of bipolar I disorder, more than 50% of manic episodes have some element of psychosis, with as many as 10% of patients showing signs of delusions 2 years after an episode, Dr. Goldberg explained. In these patients, mania relapse is predicted by mood-incongruent psychosis – a condition usually associated with schizophrenia, he said.

“If [they] have unusual beliefs and ideas, and they’re not consistent with a particular mood state, we sometimes clinically think this sounds more like a primary psychotic process,” he said. “Maybe, but not necessarily. So just because the patient may say, ‘The FBI is after me,’ or, ‘My thoughts are being read over the Internet,’ and they don’t connect that with a grandiose theme, it doesn’t negate a diagnosis of bipolar disorder.”

Psychotic mania is also associated with comorbid anxiety disorder. About half of patients with bipolar I disorder will also experience impairments of attention, executive functioning, and verbal memory separately from ADHD. “The cognitive symptoms of bipolar disorder that are part of what’s inherited doesn’t seem to be the case, that there’s a clear greater degree of neuropsychological impairment in psychotic than nonpsychotic mania,” Dr. Goldberg said.

Lithium has a poor response in the presence of psychosis in patients with bipolar disorder but performs better when the patient receives it alongside an antipsychotic. “Lithium does have value in psychotic mania,” Dr. Goldberg said. “Psychosis would be a negative prognostic sign, and certainly an indication for including an antipsychotic.”

In contrast to lithium, divalproex has shown evidence in reducing manic and psychotic symptoms similarly to haloperidol. “Divalproex may reduce mania symptoms, whether or not it’s helping psychosis. You’d think you have to get both reduced at the same time, but actually can see that even if there’s baseline psychosis, that does not diminish the chance of seeing a reduction in core mania symptoms,” Dr. Goldberg said.

Carbamazepine may also be advantageous to use over lithium when patients present with delusions, and a combination of carbamazepine and lithium may be comparable to haloperidol in combination with lithium when treating psychotic mania. “What we do know is, at least in some studies, there may be some greater value in treating psychotic mania with carbamazepine as compared to lithium, particularly when there are delusions present, more so than hallucinations or formal thought disorder,” Dr. Goldberg said.

In patients with bipolar disorder and associated psychotic mania, clinicians should avoid dopamine agonists such as amphetamine and pramipexole, as well as ketamine. While some evidence has shown that second-generation antipsychotics work to treat bipolar depression, “there’s not really an evidence base to suggest that first-generation antipsychotics are protective against depression,” Dr. Goldberg said.
 

Bipolar disorder with anxiety

An association exists between comorbid anxiety disorders in patients with bipolar disorder and having a younger age of onset, in people who are less likely to recover from an initial mood episode, in people with poorer quality of life and role functioning, and in people who are less euthymic and more likely to attempt suicide, Dr. Goldberg said.

In addition, some patients may demonstrate symptoms of anxiety that aren’t part of the DSM-5 criteria for an anxiety disorder. Dr. Goldberg said he asks his patients to specify what they mean when they say they feel anxious.

“I always ask patients to tell me in very basic terms what [they] mean by anxiety. If they say, ‘I just I can’t sit still; I’m very fidgety,’ maybe that’s akathisia,” he said. “Or maybe if they say they’re very anxious, what they mean is they have so much energy they can’t contain it. This is mania or hypomania that they’re misconstruing as anxiety. We have to be very diligent and vigilant in clarifying the language here.”

To treat comorbid anxiety in patients with bipolar disorder, consider adjunctive olanzapine or lamotrigine, as both have evidence of anxiolytic efficacy. “Olanzapine does count as an antianxiety agent. Would you use it just as an antianxiety agent? Probably not in and of itself, but there’s other compelling reasons to use it,” he said. Before assuming you need to add another medication to address anxiety in a patient, “step back and think perhaps their anxiety symptoms will in themselves remit with olanzapine,” he said. Olanzapine can also be potentially used in cases where a patient has mania and anxiety to treat both conditions, he added.

Divalproex is another option for patients that has anxiolytic efficacy. “In the context of bipolar depression, divalproex does have antianxiety properties,” Dr. Goldberg said. Other anxiolytic options include lurasidone, cariprazine, quetiapine, and combination olanzapine–fluoxetine.
 

Bipolar disorder and ADHD

Among patients with bipolar disorder and comorbid adult ADHD, cognitive dysfunction inherent to bipolar disorder may be difficult to distinguish from signs of ADHD, Dr. Goldberg explained, with about 20% of people with bipolar I disorder and about 30% of people with bipolar II disorder have deficits of attentional processing, verbal memory, and executive functioning.

“Some researchers are very intrigued by the notion that cognitive problems and attentional problems aren’t necessarily a sign of [ADHD] comorbidities. They might be, but they may just be part of the endophenotype or the non-overt, genetically driven phenomenology that makes bipolar disorder so heterogeneous,” he said.

Patients with bipolar disorder and comorbid ADHD are more likely to have mania than depression, the condition is more common in men, and these patients are more likely to have substance use problems, increased risk of suicide attempts, problems in school, lower socioeconomic status, greater unemployment history, higher divorce rates, and low family history of bipolar disorder. Clinicians should check a patient’s history if they suspect comorbid adult ADHD in their patients with bipolar disorder, as there is a good chance evidence of ADHD will be present around the time of adolescence.

“You don’t wake up with [ADHD] at age 40, at least that’s not the prevailing perspective,” Dr. Goldberg said.

Focus on the ADHD symptoms that do not overlap with bipolar disorder, such as nondiscrete, chronic symptoms; lack of psychosis and suicidality; no evidence of grandiose beliefs; lack of hypersexuality; and depression that is not prominent. “You really need to go back in time and get some clarity as to the longitudinal course. If this was present earlier on and it persists into adulthood and it’s not better accounted for by either what we think of as the cognitive pervasive problems that emerge in bipolar disorder, or in relatives as a collaborator for attentional problems and bipolar disorder, we can then contemplate [whether] there’s a plausible basis for using a stimulant or [other ADHD] treatment,” he said.

In patients who are found to have adult comorbid ADHD and are nonmanic and nonpsychotic, stimulants do have an effect. Studies suggest that amphetamines such as adjunctive lisdexamfetamine added to a mood stabilizer show an improvement in ADHD symptoms after 4 weeks (Hum Psychopharmacol. 2013; 28[5]:421-7).

Adjunctive methylphenidate added to a mood stabilizer has also shown evidence of not causing treatment-emergent mania. “If you’re going to use methylphenidate, make sure it’s in the context of an antimanic mood stabilizer,” Dr. Goldberg said. In one study, methylphenidate without a mood stabilizer caused an increase in manic episodes within 3 months (Am J Psychiatry. 2017 Apr 1;174:341-8).

“All may pose safe and effective evidence-based, albeit provisional, but evidence-based options to consider in targeting the attentional symptoms in patients with bipolar disorder,” Dr. Goldberg said.

He reported that he has been a consultant for BioXcel Therapeutics, Medscape/WebMD, Otsuka, and Sage Therapeutics. In addition, Dr. Goldberg is on the speakers bureau for Allergan, Neurocrine, Otsuka, and Sunovion; and receives royalties from American Psychiatric Publishing.

Would you use it just as an antianxiety agent? Probably not in and of itself, but there’s other compelling reasons to use it,” he said. Before assuming you need to add another medication to address anxiety in a patient, “step back and think perhaps their anxiety symptoms will in themselves remit with olanzapine,” he said. Olanzapine can also be potentially used in cases where a patient has mania and anxiety to treat both conditions, he added.

Divalproex is another option for patients that has anxiolytic efficacy. “In the context of bipolar depression, divalproex does have antianxiety properties,” Dr. Goldberg said. Other anxiolytic options include lurasidone, cariprazine, quetiapine, and combination olanzapine–fluoxetine.
 

Bipolar disorder and ADHD

Among patients with bipolar disorder and comorbid adult ADHD, cognitive dysfunction inherent to bipolar disorder may be difficult to distinguish from signs of ADHD, Dr. Goldberg explained, with about 20% of people with bipolar I disorder and about 30% of people with bipolar II disorder have deficits of attentional processing, verbal memory, and executive functioning.

“Some researchers are very intrigued by the notion that cognitive problems and attentional problems aren’t necessarily a sign of [ADHD] comorbidities. They might be, but they may just be part of the endophenotype or the non-overt, genetically driven phenomenology that makes bipolar disorder so heterogeneous,” he said.

Patients with bipolar disorder and comorbid ADHD are more likely to have mania than depression, the condition is more common in men, and these patients are more likely to have substance use problems, increased risk of suicide attempts, problems in school, lower socioeconomic status, greater unemployment history, higher divorce rates, and low family history of bipolar disorder. Clinicians should check a patient’s history if they suspect comorbid adult ADHD in their patients with bipolar disorder, as there is a good chance evidence of ADHD will be present around the time of adolescence.

“You don’t wake up with [ADHD] at age 40, at least that’s not the prevailing perspective,” Dr. Goldberg said.

Focus on the ADHD symptoms that do not overlap with bipolar disorder, such as nondiscrete, chronic symptoms; lack of psychosis and suicidality; no evidence of grandiose beliefs; lack of hypersexuality; and depression that is not prominent. “You really need to go back in time and get some clarity as to the longitudinal course. If this was present earlier on and it persists into adulthood and it’s not better accounted for by either what we think of as the cognitive pervasive problems that emerge in bipolar disorder, or in relatives as a collaborator for attentional problems and bipolar disorder, we can then contemplate [whether] there’s a plausible basis for using a stimulant or [other ADHD] treatment,” he said.

In patients who are found to have adult comorbid ADHD and are nonmanic and nonpsychotic, stimulants do have an effect. Studies suggest that amphetamines such as adjunctive lisdexamfetamine added to a mood stabilizer show an improvement in ADHD symptoms after 4 weeks (Hum Psychopharmacol. 2013; 28[5]:421-7).

Adjunctive methylphenidate added to a mood stabilizer has also shown evidence of not causing treatment-emergent mania. “If you’re going to use methylphenidate, make sure it’s in the context of an antimanic mood stabilizer,” Dr. Goldberg said. In one study, methylphenidate without a mood stabilizer caused an increase in manic episodes within 3 months (Am J Psychiatry. 2017 Apr 1;174:341-8).

“All may pose safe and effective evidence-based, albeit provisional, but evidence-based options to consider in targeting the attentional symptoms in patients with bipolar disorder,” Dr. Goldberg said.

He reported that he has been a consultant for BioXcel Therapeutics, Medscape/WebMD, Otsuka, and Sage Therapeutics. In addition, Dr. Goldberg is on the speakers bureau for Allergan, Neurocrine, Otsuka, and Sunovion; and receives royalties from American Psychiatric Publishing. Global Academy and this news organization are owned by the same parent company.

When selecting pharmacotherapy for patients with bipolar disorder, clinical and prognostic correlates will ultimately influence what treatments make the most sense for a patient – but the process is a balancing act, according to Joseph F. Goldberg, MD.

“Everything we do in medicine in general, and psychiatry, and bipolar disorder in particular is a risk-benefit analysis,” Dr. Goldberg said at the virtual Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “Everything has its side effects. We’re always balancing risks and benefits.”

Patients with bipolar disorder often present with three common subtypes of the illness: Those who have associated psychosis, comorbid anxiety disorders, and comorbid ADHD. “These are three common presentations of the many, many kinds of presentations,” said Dr. Goldberg, clinical professor of psychiatry at the Icahn School of Medicine at Mount Sinai in New York.

Bipolar disorder with associated psychosis

In the case of bipolar I disorder, more than 50% of manic episodes have some element of psychosis, with as many as 10% of patients showing signs of delusions 2 years after an episode, Dr. Goldberg explained. In these patients, mania relapse is predicted by mood-incongruent psychosis – a condition usually associated with schizophrenia, he said.

“If [they] have unusual beliefs and ideas, and they’re not consistent with a particular mood state, we sometimes clinically think this sounds more like a primary psychotic process,” he said. “Maybe, but not necessarily. So just because the patient may say, ‘The FBI is after me,’ or, ‘My thoughts are being read over the Internet,’ and they don’t connect that with a grandiose theme, it doesn’t negate a diagnosis of bipolar disorder.”

Psychotic mania is also associated with comorbid anxiety disorder. About half of patients with bipolar I disorder will also experience impairments of attention, executive functioning, and verbal memory separately from ADHD. “The cognitive symptoms of bipolar disorder that are part of what’s inherited doesn’t seem to be the case, that there’s a clear greater degree of neuropsychological impairment in psychotic than nonpsychotic mania,” Dr. Goldberg said.

Lithium has a poor response in the presence of psychosis in patients with bipolar disorder but performs better when the patient receives it alongside an antipsychotic. “Lithium does have value in psychotic mania,” Dr. Goldberg said. “Psychosis would be a negative prognostic sign, and certainly an indication for including an antipsychotic.”

In contrast to lithium, divalproex has shown evidence in reducing manic and psychotic symptoms similarly to haloperidol. “Divalproex may reduce mania symptoms, whether or not it’s helping psychosis. You’d think you have to get both reduced at the same time, but actually can see that even if there’s baseline psychosis, that does not diminish the chance of seeing a reduction in core mania symptoms,” Dr. Goldberg said.

Carbamazepine may also be advantageous to use over lithium when patients present with delusions, and a combination of carbamazepine and lithium may be comparable to haloperidol in combination with lithium when treating psychotic mania. “What we do know is, at least in some studies, there may be some greater value in treating psychotic mania with carbamazepine as compared to lithium, particularly when there are delusions present, more so than hallucinations or formal thought disorder,” Dr. Goldberg said.

In patients with bipolar disorder and associated psychotic mania, clinicians should avoid dopamine agonists such as amphetamine and pramipexole, as well as ketamine. While some evidence has shown that second-generation antipsychotics work to treat bipolar depression, “there’s not really an evidence base to suggest that first-generation antipsychotics are protective against depression,” Dr. Goldberg said.
 

Bipolar disorder with anxiety

An association exists between comorbid anxiety disorders in patients with bipolar disorder and having a younger age of onset, in people who are less likely to recover from an initial mood episode, in people with poorer quality of life and role functioning, and in people who are less euthymic and more likely to attempt suicide, Dr. Goldberg said.

In addition, some patients may demonstrate symptoms of anxiety that aren’t part of the DSM-5 criteria for an anxiety disorder. Dr. Goldberg said he asks his patients to specify what they mean when they say they feel anxious.

“I always ask patients to tell me in very basic terms what [they] mean by anxiety. If they say, ‘I just I can’t sit still; I’m very fidgety,’ maybe that’s akathisia,” he said. “Or maybe if they say they’re very anxious, what they mean is they have so much energy they can’t contain it. This is mania or hypomania that they’re misconstruing as anxiety. We have to be very diligent and vigilant in clarifying the language here.”

To treat comorbid anxiety in patients with bipolar disorder, consider adjunctive olanzapine or lamotrigine, as both have evidence of anxiolytic efficacy. “Olanzapine does count as an antianxiety agent. Would you use it just as an antianxiety agent? Probably not in and of itself, but there’s other compelling reasons to use it,” he said.

Cirrhosis may increase the risk of complications from endoscopic retrograde cholangiopancreatography (ERCP), according to a retrospective study involving almost 700 patients.

The study also showed that Child-Pugh class was a better predictor of risk than Model for End-Stage Liver Disease (MELD) score, reported lead author Michelle Bernshteyn, MD, a third-year internal medicine resident at State University of New York, Syracuse , and colleagues.

“There remains a scarcity in the literature regarding complications and adverse effects after ERCP in cirrhotic patients, particularly those incorporating Child-Pugh class and MELD score or type of intervention as predictors,” Dr. Bernshteyn said during a virtual presentation at the American College of Gastroenterology annual meeting. “Furthermore, literature review demonstrates inconsistency among results.”

To gain clarity, Dr. Bernshteyn and colleagues reviewed electronic medical records from 692 patients who underwent ERCP, of whom 174 had cirrhosis and 518 did not. For all patients, the investigators analyzed demographics, comorbidities, indications for ERCP, type of sedation, type of intervention, and complications within a 30-day period. Complications included bleeding, pancreatitis, cholangitis, perforation, mortality caused by ERCP, and mortality from other causes. Patients with cirrhosis were further analyzed based on etiology of cirrhosis, Child-Pugh class, and MELD score.

The analysis revealed that complications were significantly more common in patients with cirrhosis than in those without cirrhosis (21.30% vs. 13.51%; P = .015). No specific complications were significantly more common in patients with cirrhosis than in those without cirrhosis.

In patients with cirrhosis, 41.18% of Child-Pugh class C patients had complications, compared with 15.15% of class B patients and 19.30% of class A patients (P = .010). In contrast, MELD scores were not significantly associated with adverse events.

Further analysis showed that, in patients without cirrhosis, diagnostic-only ERCP and underlying chronic obstructive pulmonary disease were associated with high rates of complications (P = .039 and P = .003, respectively). In patients with cirrhosis, underlying chronic obstructive pulmonary disease and hypertension predicted adverse events (P = .009 and P = .003, respectively).

“The results of our study reaffirm that liver cirrhosis has an impact on the occurrence of complications during ERCP,” Dr. Bernshteyn said. “Child-Pugh class seems to be more reliable as compared to MELD score in predicting complications of ERCP in cirrhosis patients,” she added. “However, we are also aware that Child-Pugh and MELD scores are complementary to each other while evaluating outcomes of any surgery in patients with cirrhosis.”

In 2017, Udayakumar Navaneethan, MD, a gastroenterologist at AdventHealth Orlando’s Center for Interventional Endoscopy, and an assistant professor at the University of Central Florida, Orlando, and colleagues published a national database study concerning the safety of ERCP in patients with liver cirrhosis.

“[The present] study is important as it highlights the fact that ERCP is associated with significant complications in cirrhotic patients compared to those without cirrhosis,” Dr. Navaneethan said when asked to comment. “Also, Child-Pugh score appeared to be more reliable than MELD score in predicting complications of ERCP in cirrhotic patients.”

He went on to explain relevance for practicing clinicians. “The clinical implications of the study are that a detailed risk-benefit discussion needs to be done with patients with liver cirrhosis, particularly with advanced liver disease Child-Pugh class C, irrespective of the etiology,” Dr. Navaneethan said. “ERCP should be performed when there is clear evidence that the benefits outweigh the risks.” The investigators and Dr. Navaneethan reported no conflicts of interest.

A short course of radiation therapy followed by neoadjuvant chemotherapy resulted in a clinical complete response (CR) in almost half of 90 patients with locally advanced rectal cancer, allowing the majority of responders to skip surgical resection, a retrospective study indicates.

Specifically, at a median follow-up of 16.6 months for living patients, the initial clinical CR rate was 48% overall.

“While we do not have enough follow-up yet to know the late side-effect profile of this regimen, our preliminary results are promising,” Re-I Chin, MD, of Washington University School of Medicine, St. Louis, Missouri, told Medscape Medical News in an email.

The study was presented at the virtual 2020 meeting of the American Society of Radiation Oncology (ASTRO).

“Certainly, longer follow-up will be needed in this study, but none of the observed patients to date has experienced an unsalvageable failure,” said meeting discussant Amol Narang, MD, of Johns Hopkins University, Baltimore, Maryland.

He reminded conference attendees that, despite good evidence supporting equivalency in oncologic outcomes between short-course radiation and long-course chemoradiation, the former is “highly underutilized in the US” with a mere 1% usage rate between 2004 and 2014.

The current study’s short-course treatment approach was compared in this setting to long-course chemoradiation and adjuvant chemotherapy in the RAPIDO trial reported at the 2020 annual meeting of the American Society of Clinical Oncology (ASCO), Narang pointed out.

Short-course patients had a higher rate of pathological complete response (pCR) and a lower rate of treatment failure compared with patients who received long-course chemoradiation and adjuvant chemotherapy; both patient groups underwent total mesorectal excision — which is different from the current analysis. The RAPIDO investigators concluded that the approach featuring the short course “can be considered as a new standard of care.”

Narang said the data collectively “begs the question as to whether the superiority of long-course chemoradiation should really have to be demonstrated to justify its use.”

But Chin highlighted toxicity issues. “Historically, there have been concerns regarding toxicity with short-course radiation therapy since it requires larger doses of radiation given over a shorter period of time,” Chin explained. “But [the short course] is particularly convenient for patients since it saves them more than a month of daily trips to the radiation oncology department.”
 

Seven local failures

The single-center study involved patients with newly diagnosed, nonmetastatic rectal adenocarcinoma treated with short-course radiation therapy followed by chemotherapy in 2018 and 2019. Nearly all (96%) had locally advanced disease, with either a T3/T4 tumor or node-positive disease. Median tumor size was 4.6 cm.

“Many of the patients in the study had low lying tumors,” Chin reported, with a median distance from the anal verge of 7 cm.

Radiation therapy was delivered in 25 Gy given in five fractions over 5 consecutive days, with the option to boost the dose to 30 Gy or 35 Gy in five fractions if extra-mesorectal lymph nodes were involved. Conventional 3D or intensity-modulated radiation was used and all patients completed treatment.

The median interval between diagnosis of rectal cancer and initiation of radiation therapy was 1.4 months, while the median interval between completion of radiation to initiation of chemotherapy was 2.7 weeks.

The most common chemotherapy regimen was FOLFOX – consisting of leucovorin, fluorouracil (5-FU), and oxaliplatin – or modified FOLFOX. For patients who received six or more cycles of chemotherapy, the median time spent on treatment was 3.9 months.

For those who completed at least six cycles of chemotherapy, the overall clinical CR was 51%, and, for patients with locally advanced disease, the clinical CR rate was 49%. Five of the 43 patients who achieved an initial clinical CR still underwent surgical resection because of patient or physician preference. Among this small group of patients, 4 of the 5 achieved a pCR, and the remaining patient achieved a pathological partial response (pPR).

A total of 42 patients (47% of the group) achieved a partial response following the radiation plus chemotherapy paradigm, and one patient had progressive disease. All underwent surgical resection. One patient did not complete chemotherapy and did not get surgery and subsequently died.

This left 38 patients to be managed nonoperatively. In this nonoperative cohort, 79% of patients continued to have a clinical CR at the end of follow-up. Of the 7 patients with local failure, 6 were salvaged by surgery, one was salvaged by chemotherapy, and all 7 treatment failures had no evidence of disease at last follow-up.

Of the small group of 5 patients who achieved an initial clinical CR following short-course radiation therapy and neoadjuvant chemotherapy, there were no further events in this group, whereas, for patients who achieved only an initial partial response or who had progressive disease, 72% remained event-free.

Approximately half of those who achieved a clinical CR to the treatment regimen had no late gastrointestinal toxicities, and no grade 3 or 4 toxicities were observed. “Surgical resection of tumors — even without a permanent stoma — can result in significantly decreased bowel function, so our goal is to treat patients without surgery and maintain good bowel function,” Chin noted.

“For rectal cancer, both short-course radiation therapy and nonoperative management are emerging treatment paradigms that may be more cost-effective and convenient compared to long-course chemoradiation followed by surgery, [especially since] the COVID-19 pandemic...has spurred changes in clinical practices in radiation oncology,” she said.

Chin has disclosed no relevant financial relationships. Narang reports receiving research support from Boston Scientific.

“For rectal cancer, both short-course radiation therapy and nonoperative management are emerging treatment paradigms that may be more cost-effective and convenient compared to long-course chemoradiation followed by surgery, [especially since] the COVID-19 pandemic...has spurred changes in clinical practices in radiation oncology,” she said.

A short course of radiation therapy followed by neoadjuvant chemotherapy resulted in a clinical complete response (CR) in almost half of 90 patients with locally advanced rectal cancer, allowing the majority of responders to skip surgical resection, a retrospective study indicates.

Specifically, at a median follow-up of 16.6 months for living patients, the initial clinical CR rate was 48% overall.

“While we do not have enough follow-up yet to know the late side-effect profile of this regimen, our preliminary results are promising,” Re-I Chin, MD, of Washington University School of Medicine, St. Louis, Missouri, told Medscape Medical News in an email.

The study was presented at the virtual 2020 meeting of the American Society of Radiation Oncology (ASTRO).

“Certainly, longer follow-up will be needed in this study, but none of the observed patients to date has experienced an unsalvageable failure,” said meeting discussant Amol Narang, MD, of Johns Hopkins University, Baltimore, Maryland.

He reminded conference attendees that, despite good evidence supporting equivalency in oncologic outcomes between short-course radiation and long-course chemoradiation, the former is “highly underutilized in the US” with a mere 1% usage rate between 2004 and 2014.

The current study’s short-course treatment approach was compared in this setting to long-course chemoradiation and adjuvant chemotherapy in the RAPIDO trial reported at the 2020 annual meeting of the American Society of Clinical Oncology (ASCO), Narang pointed out.

Short-course patients had a higher rate of pathological complete response (pCR) and a lower rate of treatment failure compared with patients who received long-course chemoradiation and adjuvant chemotherapy; both patient groups underwent total mesorectal excision — which is different from the current analysis. The RAPIDO investigators concluded that the approach featuring the short course “can be considered as a new standard of care.”

Narang said the data collectively “begs the question as to whether the superiority of long-course chemoradiation should really have to be demonstrated to justify its use.”

But Chin highlighted toxicity issues. “Historically, there have been concerns regarding toxicity with short-course radiation therapy since it requires larger doses of radiation given over a shorter period of time,” Chin explained. “But [the short course] is particularly convenient for patients since it saves them more than a month of daily trips to the radiation oncology department.”
 

Seven local failures

The single-center study involved patients with newly diagnosed, nonmetastatic rectal adenocarcinoma treated with short-course radiation therapy followed by chemotherapy in 2018 and 2019. Nearly all (96%) had locally advanced disease, with either a T3/T4 tumor or node-positive disease. Median tumor size was 4.6 cm.

“Many of the patients in the study had low lying tumors,” Chin reported, with a median distance from the anal verge of 7 cm.

Radiation therapy was delivered in 25 Gy given in five fractions over 5 consecutive days, with the option to boost the dose to 30 Gy or 35 Gy in five fractions if extra-mesorectal lymph nodes were involved. Conventional 3D or intensity-modulated radiation was used and all patients completed treatment.

The median interval between diagnosis of rectal cancer and initiation of radiation therapy was 1.4 months, while the median interval between completion of radiation to initiation of chemotherapy was 2.7 weeks.

The most common chemotherapy regimen was FOLFOX – consisting of leucovorin, fluorouracil (5-FU), and oxaliplatin – or modified FOLFOX. For patients who received six or more cycles of chemotherapy, the median time spent on treatment was 3.9 months.

For those who completed at least six cycles of chemotherapy, the overall clinical CR was 51%, and, for patients with locally advanced disease, the clinical CR rate was 49%. Five of the 43 patients who achieved an initial clinical CR still underwent surgical resection because of patient or physician preference. Among this small group of patients, 4 of the 5 achieved a pCR, and the remaining patient achieved a pathological partial response (pPR).

A total of 42 patients (47% of the group) achieved a partial response following the radiation plus chemotherapy paradigm, and one patient had progressive disease. All underwent surgical resection. One patient did not complete chemotherapy and did not get surgery and subsequently died.

This left 38 patients to be managed nonoperatively. In this nonoperative cohort, 79% of patients continued to have a clinical CR at the end of follow-up. Of the 7 patients with local failure, 6 were salvaged by surgery, one was salvaged by chemotherapy, and all 7 treatment failures had no evidence of disease at last follow-up.

Of the small group of 5 patients who achieved an initial clinical CR following short-course radiation therapy and neoadjuvant chemotherapy, there were no further events in this group, whereas, for patients who achieved only an initial partial response or who had progressive disease, 72% remained event-free.

Approximately half of those who achieved a clinical CR to the treatment regimen had no late gastrointestinal toxicities, and no grade 3 or 4 toxicities were observed. “Surgical resection of tumors — even without a permanent stoma — can result in significantly decreased bowel function, so our goal is to treat patients without surgery and maintain good bowel function,” Chin noted.

Plagued by false starts, a few dashed hopes, but with perhaps a glimmer of light on the horizon, the race to find an effective treatment for COVID-19 continues. At last count, more than 300 treatments and 200 vaccines were in preclinical or clinical development (not to mention the numerous existing agents that are being evaluated for repurposing).

There is also a renewed interest in cannabinoid therapeutics — in particular, the nonpsychoactive agent cannabidiol (CBD) and the prospect of its modulating inflammatory and other disease-associated clinical indices, including SARS-CoV-2–induced viral load, hyperinflammation, the cytokine storm, and acute respiratory distress syndrome (ARDS).

Long hobbled by regulatory, political, and financial barriers, CBD’s potential ability to knock back COVID-19–related inflammation might just open doors that have been closed for years to CBD researchers.
 

Why CBD and why now?

CBD and the resulting therapeutics have been plagued by a complicated association with recreational cannabis use. It’s been just 2 years since CBD-based therapeutics moved into mainstream medicine — the US Food and Drug Administration (FDA) approved Epidiolex oral solution for the treatment of Lennox-Gastaut syndrome and Dravet syndrome, and in August, the FDA approved it for tuberous sclerosis complex.

CBD’s mechanism of action has not been fully elucidated, but on the basis of its role in immune responses — well described in research spanning more than two decades — it›s not surprising that cannabinoid researchers have thrown their hats into the COVID-19 drug development ring.

The anti-inflammatory potential of CBD is substantial and appears to be related to the fact that it shares 20 protein targets common to inflammation-related pathways, Jenny Wilkerson, PhD, research assistant professor at the University of Florida School of Pharmacy, Gainesville, Florida, explained to Medscape Medical News.

Among the various trials that are currently recruiting or are underway is one that is slated for completion this fall. CANDIDATE (Cannabidiol for COVID-19 Patients With Mild-to-Moderate COVID-19) is a randomized, controlled, double-blind study led by Brazilian researchers at the University of São Paulo. The study, which began recruitment this past August, enrolled 100 patients, 50 in the active treatment group (who received capsulated CBD 300 mg daily for 14 days plus pharmacologic therapy [antipyretics] and clinical measures) and 50 who received placebo.

The primary outcome is intended to help clarify the potential role of oral CBD for preventing COVID-19 disease progression, modifying disease-associated clinical indices, and modulating inflammatory parameters, such as the cytokine storm, according to lead investigator Jose Alexandre de Souza Crippa, MD, PhD, professor of neuropsychology at the Ribeirao Preto Medical School at the University of São Paulo in Brazil, in the description of the study on clinicaltrials.gov. Crippa declined to provide any additional information about the trial in an email to Medscape Medical News.
 

Calming or preventing the storm

While Crippa and colleagues wrap up their CBD trial in South America, several North American and Canadian researchers are seeking to clarify and address one of the most therapeutically challenging aspects of SARS-CoV-2 infection — the lung macrophage–orchestrated hyperinflammatory response.

Although hyperinflammation is not unique to SARS-CoV-2 infection, disease severity and COVID-19–related mortality have been linked to this rapid and prolonged surge of inflammatory cytokines (eg, interleukin 6 [IL-6], IL-10, tumor necrosis factors [TNF], and chemokines) and the cytokine storm.

“When you stimulate CB2 receptors (involved in fighting inflammation), you get a release of the same inflammatory cytokines that are involved in COVID,” Cecilia Costiniuk, MD, associate professor and researcher at the Research Institute of the McGill University Health Center, Montreal, Canada, told Medscape Medical News.

“So, if you can act on this receptor, you might be able to reduce the release of those damaging cytokines that are causing ARDS, lung damage, etc,” she explained. Targeting these inflammatory mediators has been a key strategy in research aimed at reducing COVID-19 severity and related mortality, which is where CBD comes into play.

“CBD is a very powerful immune regulator. It keeps the [immune] engine on, but it doesn’t push the gas pedal, and it doesn’t push the brake completely,” Babak Baban, PhD, professor and immunologist at the Dental College of Georgia at Augusta University, told Medscape Medical News.

To explore the effectiveness of CBD in reducing hyperactivated inflammatory reactions, Baban and colleagues examined the potential of CBD to ameliorate ARDS in a murine model. The group divided wild-type male mice into sham, control, and treatment groups.

The sham group received intranasal phosphate buffered saline; the treatment and control groups received a polyriboinosinic:polycytidylic acid (poly I:C) double-stranded RNA analogue (100 mcg daily for 3 days) to simulate the cytokine storm and clinical ARDS symptoms.

Following the second poly I:C dose, the treatment group received CBD 5 mg/kg intraperitoneally every other day for 6 days. The mice were sacrificed on day 8.

The study results, published in July in Cannabis and Cannabinoid Research, first confirmed that the poly I:C model simulated the cytokine storm in ARDS, reducing blood oxygen saturation by as much as 10% (from ±81.6% to ±72.2%).

Intraperitoneally administered CBD appeared to reverse these ARDS-like trends. “We observed a significant improvement in severe lymphopenia, a mild decline in the ratio of neutrophils to T cells, and significant reductions in levels of [inflammatory and immune factors] IL-6, IFN-gamma [interferon gamma], and in TNF-alpha after the second CBD dose,” Baban said.

There was also a marked downregulation in infiltrating neutrophils and macrophages in the lung, leading to partial restoration of lung morphology and structure. The investigators write that this suggests “a counter inflammatory role for CBD to limit ARDS progression.”

Additional findings from a follow-up study published in mid-October “provide strong data that CBD may partially assert its beneficial and protective impact through its regulation of the apelin peptide,” wrote Baban in an email to Medscape Medical News.

“Apelin may also be a reliable biomarker for early diagnosis of ARDS in general, and in COVID-19 in particular,” he wrote.

Questions remain concerning dose response and whether CBD alone or in combination with other phytocannabinoids is more effective for treating COVID-19. Timing is likewise unclear.

Baban explained that as a result of the biphasic nature of COVID-19, the “sweet spot” appears to be just before the innate immune response progresses into an inflammation-driven response and fibrotic lung damage occurs.

But Wilkerson isn’t as convinced. She said that as with a thermostat, the endocannabinoid system needs tweaking to get it in the right place, that is, to achieve immune homeostasis. The COVID cytokine storm is highly unpredictable, she added, saying, “Right now, the timing for controlling the COVID cytokine storm is really a moving target.”
 

Is safety a concern?

Safety questions are expected to arise, especially in relation to COVID-19. CBD is not risk free, and one size does not fit all. Human CBD studies report gastrointestinal and somnolent effects, as well as drug-drug interactions.

Findings from a recent systematic review of randomized, controlled CBD trials support overall tolerability, suggesting that serious adverse events are rare. Such events are believed to be related to drug-drug interactions rather than to CBD itself. On the flip side, it is nonintoxicating, and there does not appear to be potential for abuse.

“It’s generally well tolerated,” Wilkerson said. “There’ve now been several clinical trials in numerous patient population settings where basically the only time you really start to have issues is where you have patients on very select agents. But this is where a pharmacist would come into play.”

Costiniuk agreed: “Just because it’s cannabis, it doesn’t mean that there’s going to be strange or unusual effects; these people [ie, those with severe COVID-19] are in the hospital and monitored very closely.”
 

Delving into the weeds: What’s next?

Although non-COVID-19 cannabinoid researchers have encountered regulatory roadblocks, several research groups that have had the prescience to dive in at the right time are gaining momentum.

Baban’s team has connected with one of the nation’s few academic laboratories authorized to work with the SARS-CoV-2 virus and are awaiting protocol approval so that they can reproduce their research, this time using two CBD formulations (injectable and inhaled).

If findings are positive, they will move forward quickly to meet with the FDA, Baban said, adding that the team is also collaborating with two organizations to conduct human clinical trials in hopes of pushing up timing.

The initial article caught the eye of the World Health Organization, which included it in its global literature on the coronavirus resource section.

Israeli researchers have also been quite busy. InnoCan Pharma and Tel Aviv University are collaborating to explore the potential for CBD-loaded exosomes (minute extracellular particles that mediate intracellular communication, including via innate and adaptive immune responses). The group plans to use these loaded exosomes to target and facilitate recovery of COVID-19–damaged lung cells.

From a broader perspective, the prospects for harnessing cannabinoids for immune modulation will be more thoroughly explored in a special issue of Cannabis and Cannabinoid Research, which has extended its current call for papers, studies, abstracts, and conference proceedings until the end of December.

Like many of the therapeutic strategies under investigation for the treatment of COVID-19, studies in CBD may continue to raise more questions than answers.

Still, Wilkerson is optimistic. “Taken together, these studies along with countless others suggest that the complex pharmacophore of Cannabis sativa may hold therapeutic utility to treat lung inflammation, such as what is seen in a COVID-19 cytokine storm,» she told Medscape Medical News. “I’m very excited to see what comes out of the research.”

Baban, Wilkerson, and Costiniuk have disclosed no relevant financial relationships.

The initial article caught the eye of the World Health Organization, which included it in its global literature on the coronavirus resource section.

Israeli researchers have also been quite busy. InnoCan Pharma and Tel Aviv University are collaborating to explore the potential for CBD-loaded exosomes (minute extracellular particles that mediate intracellular communication, including via innate and adaptive immune responses). The group plans to use these loaded exosomes to target and facilitate recovery of COVID-19–damaged lung cells.

From a broader perspective, the prospects for harnessing cannabinoids for immune modulation will be more thoroughly explored in a special issue of Cannabis and Cannabinoid Research, which has extended its current call for papers, studies, abstracts, and conference proceedings until the end of December.

Like many of the therapeutic strategies under investigation for the treatment of COVID-19, studies in CBD may continue to raise more questions than answers.

Still, Wilkerson is optimistic. “Taken together, these studies along with countless others suggest that the complex pharmacophore of Cannabis sativa may hold therapeutic utility to treat lung inflammation, such as what is seen in a COVID-19 cytokine storm,» she told Medscape Medical News. “I’m very excited to see what comes out of the research.”

Baban, Wilkerson, and Costiniuk have disclosed no relevant financial relationships.

Apomorphine sublingual film (Kynmobi, Sunovion Pharmaceuticals) was efficacious and generally safe and well tolerated for the on-demand treatment of off episodes in Parkinson’s disease, long-term follow-up of a phase 3 study has shown. Besides the usual adverse effects with apomorphine, the sublingual film was associated with more oral adverse effects than seen with the injectable drug. However, it may have some advantages over subcutaneous apomorphine injections in terms of administration during off episodes.

The study was presented at the Movement Disorder Society 23rd International Congress of Parkinson’s Disease and Movement Disorders (Virtual) 2020.

For example, the new formulation is more convenient than carrying an injection. It comes in a small, tear-open packet that contains a medication strip patients place under their tongues.

“When a patient is in the off state, depending on how off they are, they could have a little difficulty opening the strip [packet], but anyone can open the strip for them,” said lead author Rajesh Pahwa, MD, professor of neurology and chief of the Parkinson and Movement Disorder Division at the University of Kansas Medical Center in Kansas City. “On the other hand with the subcutaneous, they have to give the injection themselves and a stranger or someone is not going to help them with that.”
 

Open-label safety and efficacy study

The aims of this open-label, 48-week follow-up were to add new patients to assess safety and tolerability over the long term and to see if continued benefit from a previous 12-week double-blind study was still present at 1 year for patients in the earlier study.

This multicenter study (NCT02542696) included “rollover” patients (n = 78 for safety; n = 70 for efficacy) from the previous phase 2/3 double-blind trial, as well as new patients with no prior exposure to apomorphine sublingual film (n = 347 for safety; n = 275 for efficacy).

New patients experienced one or more off episodes per day with a daily off time of 2 hours or more per day while on stable doses of levodopa/carbidopa. All had clinically meaningful responses to levodopa/carbidopa and were judged by the investigator to be Stage 1-3 by modified Hoehn and Yahr scale rating during ON periods.

Rollover patients completed the prior study and had no major changes in their anti-Parkinson’s medications since then. Mouth cankers or sores were exclusion criteria for either group. New subjects could not have received subcutaneous apomorphine within 7 days of a screening visit.

The demographics and baseline characteristics of the new and rollover groups were similar (approximately 64 years; 65%-71% male; 96% White; 8.3-9.6 years since diagnosis; 3.9 to 4.1 off episodes/day, and total mean daily levodopa dose of 1120 to 1478 mg).

Assessing only the group of new patients, the investigators reported that 80% had a Hoehn and Yahr score of 2 or 2.5 when in the ON state and a Movement Disorder Society–Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part III predose score of 41.8.

At the beginning of this study, patients in an off period received titrated doses of 10-35 mg of sublingual apomorphine in 5 mg increments during sequential office visits until they achieved a tolerable full ON within 45 minutes of a dose. They then entered a 48-week safety and efficacy phase, during which they self-administered the drug at home up to five times daily for off episodes with a minimum of 2 hours between doses. The investigators could adjust the doses for safety or lack of efficacy.

Two-thirds of new patients and three-quarters of rollovers received doses in the 10-20 mg range. The highest dose in the study of 35 mg was used by only 8%-9% of patients, but the highest approved and marketed dose is 30 mg.
 

Long-term benefits

Onset of efficacy was achieved by 15 minutes after dose for both new and rollover patients, and maximal efficacy occurred by 30 minutes. Results were very similar at 24, 36, and 48 weeks. The investigators did not perform statistical analyses.

Across study weeks 1, 12, 24, 36, and 48, between 77% and 92% of new patients and between 65% and 77% of rollover patients self-reported full ON within 30 minutes. “The long-term benefits are maintained over a year as far as the speed of onset and the duration,” Dr. Pahwa said.

Treatment-emergent adverse events occurred in about half of the new and the rollover patient groups in the titration phase and in 71%-81% of patients during the long-term safety phase. Nearly all were mild to moderate in severity.

A large number of participants withdrew from this long-term safety phase because of adverse events – 90 (33%) of new enrollees and 16 (23%) of rollover patients. Only 4% dropped out for lack of efficacy, all in the new enrollee group. Because the sublingual formulation is delivered under the tongue, patients in that group had more oral side effects, Dr. Pahwa said. Otherwise, “the side effects were very similar to the subcutaneous delivery.”

Treatment-emergent adverse events specific to sublingual apomorphine included oral mucosal erythema, lip or tongue swelling, and mouth ulceration (6% to 7% of patients each). Occurring less often were glossodynia, oral candidiasis, stomatitis, and tongue ulceration (2% each).

These were in addition to adverse events typically occurring with subcutaneous apomorphine, which are nausea, falls, dizziness, somnolence, dyskinesia, syncope, and yawning.

There are no head-to-head comparisons of sublingual versus subcutaneous delivery of apomorphine. But based on experience, Dr. Pahwa said, “With the subcutaneous, you have a slightly faster onset of action compared to the sublingual. However, sublingual has a slightly longer duration of benefit.”

He predicted that patients may prefer using an injection for a faster benefit or a sublingual for a slightly longer benefit.
 

More therapeutic options are welcome

Commenting on the study, Ray Dorsey, MD, professor of neurology at the University of Rochester (N.Y.), said that, for people with more advanced Parkinson’s disease “there’s usually a caregiver who’s injecting someone with an off period, as opposed to sublingual, which seems like a much easier way of administering a drug, especially for people with motor fluctuations.”

He noted that adverse events that led to premature discontinuation from the study “are concerning about the overall tolerability of the drug, which also will be determined in clinical practice, and will likely influence its overall utility.”

However, more therapeutic options are welcome because “the number of people with advanced Parkinson’s disease is going to grow and grow substantially,” he said. “So having therapies that help people with more advanced Parkinson’s disease ... many of whom don’t reach the clinic ... are going to be increasingly important.”

The study was supported by Sunovion. Dr. Pahwa and Dr. Dorsey reported conflicts of interest with numerous sources in industry.
