An experimental drug that combines fixed doses of extended-release (ER) formulations of existing medications can significantly reduce symptoms in patients with untreated early-stage Parkinson’s disease, new research suggests. Results from a phase 3 trial of P2B001, a combination of pramipexole and rasagiline at currently unavailable low doses, showed the drug was more effective than its individual components and as effective as higher-dose pramipexole ER – with far less daytime sleepiness.

The combination drug is taken once per day and does not require titration, which investigators say make it a good option for first-line treatment of Parkinson’s disease.

“I don’t think people, including me, expected intuitively that if you used small doses and combined it with a little rasagiline it would be equal to full doses of pramipexole, but it appears that it is,” said lead investigator Warren Olanow, MD, professor and chair emeritus of neurology and professor emeritus of neuroscience at Icahn School of Medicine at Mount Sinai, New York.

The findings were presented at the 2022 annual meeting of the American Academy of Neurology.
 

‘Synergistic effects’

Levodopa is considered to be the most effective treatment for Parkinson’s disease, but long-term use is associated with increased risk for motor complications, such as dyskinesia. Dopamine agonists such as pramipexole have been linked in previous research to excessive daytime sleepiness and impulse control disorders. In addition, monoamine oxidase-B inhibitors such as rasagiline are not as effective at controlling Parkinson’s disease as other treatment options.

“There is no consistent agreement on how to initiate treatment because no one treatment is ideal,” Dr. Olanow said.

P2B001, developed by Pharma Two B, is a combination of 0.6 mg of pramipexole and 0.75 mg of rasagiline. The drugs work by dual mechanisms, which investigators suspected might have “synergistic effects.”

Following promising results from an earlier trial, researches launched a phase 3, 12-week, international, randomized, double-blind trial to study the efficacy, safety, and tolerability of P2B001, compared with its individual components and with a calibration arm of pramipexole ER in 519 patients with early Parkinson’s disease.

Participants received P2B001, 0.6 mg of pramipexole ER, 0.75 mg of rasagiline ER, or pramipexole ER titrated to an optimal dose for each patient (1.5-4.5 mg).
 

New first-line treatment?

Results showed that the adjusted mean change from baseline in total Unified Parkinson’s Disease Rating Scale (UPDRS) score was -2.66 points for P2B001 versus pramipexole (P = .0018) and -3.30 points for P2B001 versus rasagiline (P = .0001).

There was no significant difference in UPDRS scores between P2B001 and pramipexole ER, but patients who received P2B001 reported significantly less daytime sleepiness.

The adjusted mean change from baseline in Epworth Sleepiness Scale score for P2B001 versus pramipexole ER was -2.66 points (P < .0001).

In addition, fewer dopaminergic adverse events were reported with the combination drug versus pramipexole ER (44.7% vs. 66.2%), including somnolence (14.7% vs. 31.1%) and orthostatic hypotension (2.7% vs. 12.2%).

As a first-line treatment, P2B001 could offer an effective option instead of levodopa, Dr. Olanow said. “It could be really good for patients because it would delay the introduction of levodopa and allow levodopa to be used in lower doses when the time comes and hopefully reduce the risk of complications,” he added.
 

Questions, cost concerns

Commenting on the study, Alfonso Fasano, MD, PhD, professor of neurology and chair in neuromodulation, University of Toronto, agreed that better therapeutic options are needed for Parkinson’s disease.

Combining available treatments into one pill “might help patients’ adherence, although this can compromise our ability to dose each compound individually,” said Dr. Fasano, who was not involved with the research.

He added that there are also questions about dosage modification as a patient’s disease progresses and whether a higher dose might pose safety problems. There is also the issue of cost. “Conducting large clinical trials like this one is expensive, and I wonder about the cost of the drug when approved,” Dr. Fasano noted. “Do we really need to invest in combination pills containing two already well-known compounds?”

Dr. Olanow, who is not directly involved with Pharma Two B, the developer of P2B001, said he has no information on what the drug might cost or how it might be marketed if approved for use.

“The advantage of the combination is the component doses are not replicable, they are both in an extended-release formulation, it doesn’t require titration, and it has been tested and proven to work,” he said.

The study was funded by Pharma Two B. Dr. Olanow is employed by Clintrex Research Corporation and owns stock in Clintrex Research Corporation. Dr. Fasano reported no relevant financial relationships.

BOSTON – The use of carbon dioxide (CO2) laser excision therapy for hidradenitis suppurativa (HS) is not associated with an increased risk for the development of keloids, new research shows.

“With keloids disproportionately affecting Black and other skin of color patients, denying treatment on a notion that lacks evidentiary support further potentiates the health disparities experienced by these marginalized groups,” the researchers reported at the Annual Meeting of the Skin of Color Society Scientific Symposium (SOCS) 2022. In their retrospective study of 129 patients with HS treated with CO2 laser, “there were no cases of keloid formation,” they say.

HS, a potentially debilitating chronic inflammatory condition that involves painful nodules, boils, and abscesses, is often refractory to standard treatment. CO2 laser excision therapy has yielded favorable outcomes in some studies.

Although CO2 laser therapy is also used to treat keloids, some clinicians hesitate to use this treatment in these patients because of concerns that its use for treating HS could trigger the development of keloids.

“Many patients come in telling us they were denied [CO2 laser] surgery due to keloids,” senior author Iltefat Hamzavi, MD, a senior staff physician in the Department of Dermatology at the Henry Ford Health System, Detroit, told this news organization.

Regarding patient selection, he noted that “the disease should be medically stable with reduction in drainage to help control postop bleeding risk.”

The findings of the study are supported by a recent systematic review that compared outcomes and adverse effects of treatment with ablative laser therapies with nonablative lasers for skin resurfacing. The review included 34 studies and involved 1,093 patients. The conditions that were treated ranged from photodamage and acne scars to HS and post-traumatic scarring from basal cell carcinoma excision.

That review found that overall, rates of adverse events were higher with nonablative therapies (12.2%, 31 events), compared with ablative laser therapy, such as with CO2 laser (8.28%, 81 events). In addition, when transient events were excluded, ablative lasers were associated with fewer complications overall, compared with nonablative lasers (2.56% vs. 7.48%).

The authors conclude: “It is our hope that this study will facilitate continued research in this domain in an effort to combat these inequities and improve access to CO2 excision or standardized excisional therapy for hidradenitis suppurativa treatment.”

Dr. Hamzavi and the other authors have disclosed no relevant financial relationships.

The Diagnosis: Cutaneous B-cell Lymphoma

Shave biopsies of 3 lesions revealed a dense, diffuse, atypical lymphoid infiltrate occupying the entirety of the dermis and obscuring the dermoepidermal junction. The infiltrate consisted predominantly of largesized lymphoid cells with fine chromatin and conspicuous nucleoli (Figure). Immunohistochemistry was positive for CD45 and CD20, indicating B-cell lineage. Bcl-2, multiple myeloma oncogene 1, and forkhead box protein P1 also were expressed in the vast majority of lesional cells, distinguishing the lesion from other forms of cutaneous B-cell lymphomas.¹ These findings were consistent with large B-cell lymphoma with a high proliferation index, consistent with primary cutaneous diffuse large B-cell lymphoma, leg type, which often presents on the lower leg.² The patient had a negative systemic workup including bone marrow biopsy. He was started on the R-CEOP (rituximab, cyclophosphamide, etoposide, vincristine, prednisone) chemotherapy regimen.

Primary cutaneous diffuse large B-cell lymphoma, leg type, is an intermediately aggressive and rare form of B-cell lymphoma with a poor prognosis that primarily affects elderly female patients. Primary cutaneous diffuse large B-cell lymphoma, leg type, accounts for only 1% to 3% of cutaneous lymphomas and approximately 10% to 20% of primary cutaneous B-cell lymphomas.² It typically presents as multiple red-brown or bluish nodules on the lower extremities or trunk. Presentation as a solitary nodule also is possible.^1,2 Histologic analysis of primary cutaneous diffuse large B-cell lymphoma, leg type, reveals large cells with round nuclei (immunoblasts and centroblasts), and the immunohistochemical profile shows strong Bcl-2 expression often accompanied by the multiple myeloma oncogene 1 protein.³ The 5-year survival rate is approximately 50%, which is lower than other types of primary cutaneous B-cell lymphomas, and the progression of disease is characterized by frequent relapses and involvement of extracutaneous regions such as the lymph nodes, bone marrow, and central nervous system.^1,2,4 Patients with multiple tumors on the leg have a particularly poor prognosis; in particular, having 1 or more lesions on the leg results in a 43% 3-year survival rate while having multiple lesions has a 36% 3-year survival rate compared with a 77% 3-year survival rate for patients with the non–leg subtype or a single lesion.3 Treatment with rituximab has been shown to be effective in at least short-term control of the disease, and the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen is the standard of treatment.^3,4

Primary cutaneous diffuse large B-cell lymphoma, leg type, can mimic multiple other cutaneous presentations of disease. Myeloid sarcoma (leukemia cutis) is a rare condition that presents as an extramedullary tumor often simultaneously with the onset or relapse of acute myeloid leukemia.⁵ Our patient had no history of leukemia, but myeloid sarcoma may predate acute myeloid leukemia in about a quarter of cases.⁵ It most commonly presents histologically as a diffuse dermal infiltrate that splays between collagen bundles and often is associated with an overlying Grenz zone. A nodular, or perivascular and periadnexal, pattern also may be seen. Upon closer inspection, the infiltrate is composed of immature myeloid cells (blasts) with background inflammation occasionally containing eosinophils. The immunohistochemical profile varies depending on the type of differentiation and degree of maturity of the cells. The histologic findings in our patient were inconsistent with myeloid sarcoma.

Erythema elevatum diutinum (EED) usually presents as dark red, brown, or violaceous papules or plaques and often is found on the extensor surfaces. It often is associated with hematologic abnormalities as well as recurrent bacterial or viral infections.⁶ Histologically, EED initially manifests as leukocytoclastic vasculitis with a mixed inflammatory infiltrate typically featuring an abundance of neutrophils, making this condition unlikely in this case. As the lesion progresses, fibrosis and scarring ensue as inflammation wanes. The fibrosis often is described as having an onion skin–like pattern, which is characteristic of established EED lesions. Our patient had no history of vasculitis, and the histologic findings were inconsistent with EED.

Angiosarcoma can present as a central nodule surrounded by an erythematous plaque. Although potentially clinically similar to primary cutaneous diffuse large B-cell lymphoma, leg type, angiosarcoma was unlikely in this case because of an absence of lymphedema and no history of radiation to the leg, both of which are key historical features of angiosarcoma.⁷ Additionally, the histology of cutaneous angiosarcoma is marked by vascular proliferation, which was not seen in the lesion biopsied in our patient. The histology of angiosarcoma is that of an atypical vascular proliferation, and a hallmark feature is infiltration between collagen, often referred to as giving the appearance of dissection between collagen bundles. The degree of atypia can vary widely, and epithelioid variants exist, producing a potential diagnostic pitfall. Lesional cells are positive for vascular markers, which can be used for confirmation of the endothelial lineage.

Sarcoidosis is notorious for its mimicry, which can be the case both clinically and histologically. Characteristic pathology of sarcoidosis is that of well-formed epithelioid granulomas with minimal associated inflammation and lack of caseating necrosis. Our patient had no known history of systemic sarcoidosis, and the pathologic features of noncaseating granulomas were not present. As a diagnosis of exclusion, correlation with special stains and culture studies is necessary to exclude an infectious process. The differential diagnosis for sarcoidal granulomatous dermatitis also includes foreign body reaction, inflammatory bowel disease, and granulomatous cheilitis, among others.

He was started on the R-CEOP (rituximab, cyclophosphamide, etoposide, vincristine, prednisone) chemotherapy regimen.

Primary cutaneous diffuse large B-cell lymphoma, leg type, is an intermediately aggressive and rare form of B-cell lymphoma with a poor prognosis that primarily affects elderly female patients. Primary cutaneous diffuse large B-cell lymphoma, leg type, accounts for only 1% to 3% of cutaneous lymphomas and approximately 10% to 20% of primary cutaneous B-cell lymphomas.² It typically presents as multiple red-brown or bluish nodules on the lower extremities or trunk. Presentation as a solitary nodule also is possible.^1,2 Histologic analysis of primary cutaneous diffuse large B-cell lymphoma, leg type, reveals large cells with round nuclei (immunoblasts and centroblasts), and the immunohistochemical profile shows strong Bcl-2 expression often accompanied by the multiple myeloma oncogene 1 protein.³ The 5-year survival rate is approximately 50%, which is lower than other types of primary cutaneous B-cell lymphomas, and the progression of disease is characterized by frequent relapses and involvement of extracutaneous regions such as the lymph nodes, bone marrow, and central nervous system.^1,2,4 Patients with multiple tumors on the leg have a particularly poor prognosis; in particular, having 1 or more lesions on the leg results in a 43% 3-year survival rate while having multiple lesions has a 36% 3-year survival rate compared with a 77% 3-year survival rate for patients with the non–leg subtype or a single lesion.3 Treatment with rituximab has been shown to be effective in at least short-term control of the disease, and the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen is the standard of treatment.^3,4

Primary cutaneous diffuse large B-cell lymphoma, leg type, can mimic multiple other cutaneous presentations of disease. Myeloid sarcoma (leukemia cutis) is a rare condition that presents as an extramedullary tumor often simultaneously with the onset or relapse of acute myeloid leukemia.⁵ Our patient had no history of leukemia, but myeloid sarcoma may predate acute myeloid leukemia in about a quarter of cases.⁵ It most commonly presents histologically as a diffuse dermal infiltrate that splays between collagen bundles and often is associated with an overlying Grenz zone. A nodular, or perivascular and periadnexal, pattern also may be seen. Upon closer inspection, the infiltrate is composed of immature myeloid cells (blasts) with background inflammation occasionally containing eosinophils. The immunohistochemical profile varies depending on the type of differentiation and degree of maturity of the cells. The histologic findings in our patient were inconsistent with myeloid sarcoma.

Erythema elevatum diutinum (EED) usually presents as dark red, brown, or violaceous papules or plaques and often is found on the extensor surfaces. It often is associated with hematologic abnormalities as well as recurrent bacterial or viral infections.⁶ Histologically, EED initially manifests as leukocytoclastic vasculitis with a mixed inflammatory infiltrate typically featuring an abundance of neutrophils, making this condition unlikely in this case. As the lesion progresses, fibrosis and scarring ensue as inflammation wanes. The fibrosis often is described as having an onion skin–like pattern, which is characteristic of established EED lesions. Our patient had no history of vasculitis, and the histologic findings were inconsistent with EED.

Angiosarcoma can present as a central nodule surrounded by an erythematous plaque. Although potentially clinically similar to primary cutaneous diffuse large B-cell lymphoma, leg type, angiosarcoma was unlikely in this case because of an absence of lymphedema and no history of radiation to the leg, both of which are key historical features of angiosarcoma.⁷ Additionally, the histology of cutaneous angiosarcoma is marked by vascular proliferation, which was not seen in the lesion biopsied in our patient. The histology of angiosarcoma is that of an atypical vascular proliferation, and a hallmark feature is infiltration between collagen, often referred to as giving the appearance of dissection between collagen bundles. The degree of atypia can vary widely, and epithelioid variants exist, producing a potential diagnostic pitfall. Lesional cells are positive for vascular markers, which can be used for confirmation of the endothelial lineage.

Sarcoidosis is notorious for its mimicry, which can be the case both clinically and histologically. Characteristic pathology of sarcoidosis is that of well-formed epithelioid granulomas with minimal associated inflammation and lack of caseating necrosis. Our patient had no known history of systemic sarcoidosis, and the pathologic features of noncaseating granulomas were not present. As a diagnosis of exclusion, correlation with special stains and culture studies is necessary to exclude an infectious process. The differential diagnosis for sarcoidal granulomatous dermatitis also includes foreign body reaction, inflammatory bowel disease, and granulomatous cheilitis, among others.

U.K. scientists said microplastics may pose even more of a threat than previously thought after confirming their presence in lung tissue taken from living people.

Microplastics were identified in all lung regions, but significantly higher levels were found in the lower lung.

The results supported inhalation as an exposure risk, according to the team from the University of Hull and Hull York Medical School (England), who said their findings could support further investigations into the effects of airborne microplastics on respiratory health.

The study, published in Science of the Total Environment, used lung tissue collected from surgical procedures on patients during routine medical care at Castle Hill Hospital in East Yorkshire.
 

Polypropylene and polyethylene

It found 39 microplastics in 11 of the 13 lung tissue samples tested using micro-Fourier-transform infrared (μFTIR) analysis, which the scientists said was considerably higher than results from previous laboratory tests.

Of microplastics detected, 12 polymer types were identified, of which the most common were polypropylene, (23%) polyethylene terephthalate (18%), and resin (15%). The fibers are commonly found in packaging, bottles, clothing, rope and twine manufacture, and other industries, the scientists said.

Microplastics with dimensions as small as 4 μm were found, but the scientists said they were surprised to discover samples as large as greater than 2 mm within all lung region samples, with the majority being fibrous and fragmented.

The study identified 11 microplastics in the upper part of the lung, seven in the mid part, and 21 in the lower part of the lung.

Laura Sadofsky, the study’s lead author, said: “Microplastics have previously been found in human cadaver autopsy samples. This is the first robust study to show microplastics in lungs from live people. It also shows that they are in the lower parts of the lung. Lung airways are very narrow, so no one thought they could possibly get there, but they clearly have.”

There were also considerably higher levels of microplastics found in male patients, compared with female patients.
 

Future investigations into health implications

“The characterization of types and levels of microplastics we have found can now inform realistic conditions for laboratory exposure experiments with the aim of determining health impacts,” said Laura Sadofsky, who is a senior lecturer in respiratory medicine in the Centre for Atherothrombotic and Metabolic Research at Hull York Medical School.

The latest investigation followed previous research by the medical school and the University of Hull, which found high levels of atmospheric microplastics within the Humber region.

That study, published in Atmosphere, identified resins, which could have originated from degraded roads, paint marking, or tire rubber, as well as polyethylene fibers.

When Sigmund Freud claimed that “anatomy is destiny” he was referring to anatomical sex as a determinant of personality traits. Expert consensus statements have previously offered some recommendations for managing these syndromes, but clinical data are scarce, so the present review “is intended to establish a starting point for future research,”

That notion has been widely discredited, but Freud appears to be inadvertently right in one respect: When it comes to chronic obstructive pulmonary disease (COPD), anatomy really is destiny, and sex may be as well, pulmonary researchers say.

There is a growing body of evidence to indicate that COPD affects men and women differently, and that men and women patients with COPD require different clinical management. Yet women are often underdiagnosed or misdiagnosed, partly because of poorly understood sex differences, but also because of cultural biases.

But plunging any farther into the weeds, it’s important to define terms. Although various investigators have used the terms “sex” and “gender” interchangeably, sex is the preferred term when referring to biological attributes of individual patients, while gender refers to personal identity.

These distinctions are important, contended Amik Sodhi, MBBS, MPH, from the division of allergy, pulmonology, and critical care medicine at the University of Wisconsin–Madison.

“Sex is essentially a biologic construct, so it’s got to do with the sex chromosomes, the genetics of that person, and it refers to the anatomic variations that can change susceptibility to different diseases,” she said in an interview.

An example of sex differences or “sexual dimorphism” can be found in a recent meta-analysis of sex-based genetic associations by Megan Hardin, MD, MPH from Brigham & Women’s Hospital in Boston and colleagues.

They reported that CELSR1, a gene involved in fetal lung development, was expressed more among women than among men and that a single nucleotide polymorphism in the gene was associated with COPD among women smokers, but not among men smokers.

The finding points to a potential risk locus for COPD in women, and could help shed light on sexual dimorphism in COPD, Dr. Hardin and colleagues said.

In contrast to sex, “gender is more of a psychosocial construct which can impact how diseases manifest themselves, how they are potentially managed, and what outcomes might occur for that particular disease,” Dr. Sodhi said.

She and her colleagues recently published a review of sex and gender in common lung disorders and sleep in the journal CHEST, where they wrote that the “influence of sex and gender is portrayed in epidemiological data, disease pathogenesis and pathophysiology, clinical manifestations, response to treatment, access to care, and health outcomes. Hence, sex and gender should be considered in all types of research, clinical practice and educational curricula.”

For example, as previously reported at the 2021 annual meeting of the American Thoracic Society, sex-specific differences in the severity of symptoms and prevalence of comorbidities in patients with COPD may point to different criteria for diagnosing cardiac comorbidities in women and men.

Those conclusions came from a retrospective analysis of data on 795 women and 1,251 men with GOLD (Global Initiative for Chronic Obstructive Lung Disease) class 1-3 disease.

The investigators looked at the patients’ clinical history, comorbidities, lung function, COPD Assessment Test scores, and modified Medical Research Council (mMRC) dyspnea score, and found significant differences between men and women for most functional parameters and comorbidities, and for CAT items of cough, phlegm, and energy.

In logistic regression analysis, predictors for cardiac disease in men were energy, mMRC score, smoking status, body mass index, age, and spirometric lung function, but in women only age was significantly predictive for cardiac disease.

An example of gender effects on COPD differences in men and women is the increase in cigarette advertising aimed at women in the 1960s and the advent of women-targeted brands such as Virginia Slims, which in turn lead to increased smoking rates among women. In addition, in the developing world, where the sex/gender gap in COPD is narrowing, women tend to have greater exposure to wood smoke and cooking fuels in unventilated or poorly ventilated spaces, compared with men.
 

Increasing incidence among women

According to the Centers for Disease Control and Prevention, chronic lower respiratory diseases, primarily COPD, were the fourth-leading cause of death in women in the United States in 2018, following only heart disease, cancer, and accidents/injuries.

And as a CDC analysis of data from the 2013 Behavioral Risk Factor Surveillance System showed, women were more likely to report being told by a physician that they had COPD than did men (6.6%, compared with 5.4%).

Dr. Sodhi and colleagues noted that, at all time points examined from 2005 to 2014, women had a higher proportion than men of COPD hospitalizations and in-hospital deaths. They also noted that female sex is associated with a threefold risk for severe early-onset COPD, and that women with COPD have lower diffusion capacity of lungs for carbon monoxide, despite having higher predicted forced expiratory volume in 1 second, compared with men.

“Historically, COPD wasn’t a disease that was so prevalent in women. It’s been in the past 20 years that the trends have changed,” said Patricia Silveyra, MSc, PhD, ATSF, associate professor of environmental and occupational health at Indiana University, Bloomington.

The increasing prevalence of COPD among women cannot be explained by smoking alone, she said in an interview.

“It used to be thought that it was because more women smoked, but actually a lot of women who don’t smoke can develop COPD, so it appears to be probably something environmental, but because it used to be a disease of older men, in the clinic there was also a bias to diagnose men with COPD, and women with asthma, so a lot of women went underdiagnosed,” Dr. Silveyra said.

In their review, Dr. Sodhi and colleagues noted that women with COPD “may be underdiagnosed as a result of having different symptoms from those classically recognized. Reasons for underdiagnosis or a delay in diagnosis may also be due to lack of a formal evaluation with spirometry, women seeking care later in the course of disease, physician bias, or associated fatigue or depression misdirecting diagnostic strategies. Underdiagnosis may be associated with psychological distress and worse health-related quality of life.”

Although the evidence is mixed, women tend to present more frequently with the chronic bronchitis phenotype of COPD, compared with the emphysema phenotype, and women tend to have greater degrees of pulmonary function impairment when exposed to tobacco smoke, even after controlling for differences in height and weight.

“For the same amount of exposure to tobacco smoke, females are likely to develop more severe airflow limitation at an earlier age than males, and have more exacerbation,” Dr. Sodhi and colleagues wrote.

Both Dr. Silveyra and Dr. Sodhi said that reason why men and women differ in their physiological reactions to smoke are still unknown.
 

Sex differences in drug responses

There is only limited evidence to indicate that women and men respond differently to various therapeutic agents, but what is clear is that more research into this area is needed, Dr. Sodhi and Dr. Silveyra said.

For example, among the few studies that have documented sex differences, one showed no sex differences in the efficacy of salmeterol/fluticasone combination therapy for reducing exacerbations or improving quality of life, whereas another showed that women were more likely than men to experience COPD symptoms or exacerbations after stopping inhaled corticosteroids, Dr. Sodhi and colleagues noted.

Both Dr. Sodhi and Dr. Silveyra emphasized the need for clinical trials that study the effects of sex on treatment outcomes in COPD, which could lead to better, more personalized therapeutic regimens that take sex and gender into account.

Dr. Sodhi and colleagues offered the following advice to clinicians: “Interaction with female patients should take into account that their symptoms may not conform to traditionally accepted presentations. Challenges exist for female patients at all levels of health care interaction and as clinicians we need to acknowledge the bias and willfully work toward recognition and elimination of unconscious and conscious bias. Empowering our patients to have frank discussions with their health care team when they perceive bias is another step to help promote equity.”

The review by Dr. Sodhi and colleagues was supported by grants from the National Institutes of Health. Dr. Sodhi and Dr. Silveyra reported having no conflicts of interest to disclose.

Both Dr. Silveyra and Dr. Sodhi said that reason why men and women differ in their physiological reactions to smoke are still unknown.
 

Sex differences in drug responses

There is only limited evidence to indicate that women and men respond differently to various therapeutic agents, but what is clear is that more research into this area is needed, Dr. Sodhi and Dr. Silveyra said.

For example, among the few studies that have documented sex differences, one showed no sex differences in the efficacy of salmeterol/fluticasone combination therapy for reducing exacerbations or improving quality of life, whereas another showed that women were more likely than men to experience COPD symptoms or exacerbations after stopping inhaled corticosteroids, Dr. Sodhi and colleagues noted.

Both Dr. Sodhi and Dr. Silveyra emphasized the need for clinical trials that study the effects of sex on treatment outcomes in COPD, which could lead to better, more personalized therapeutic regimens that take sex and gender into account.

Dr. Sodhi and colleagues offered the following advice to clinicians: “Interaction with female patients should take into account that their symptoms may not conform to traditionally accepted presentations. Challenges exist for female patients at all levels of health care interaction and as clinicians we need to acknowledge the bias and willfully work toward recognition and elimination of unconscious and conscious bias. Empowering our patients to have frank discussions with their health care team when they perceive bias is another step to help promote equity.”

The review by Dr. Sodhi and colleagues was supported by grants from the National Institutes of Health. Dr. Sodhi and Dr. Silveyra reported having no conflicts of interest to disclose.

The decline in new cases of child COVID-19 in the last week continued at about the same, somewhat slower pace as the week before, but admissions have moved upward slightly, according to the most recent data.

The total number of new cases came to 25,915 for the week of April 1-7, down by 5.8% from the previous week’s 27,521, which, in turn, was 5.2% lower than a week earlier, according to the American Academy of Pediatrics and the Children’s Hospital Association, which have been collecting COVID-related data from state and territorial health departments since the early stages of the pandemic. New case declines in previous weeks had ranged from 9.3% to 46%.

The nearly 26,000 cases reported during the first week of April represent a fall of 97.7% from the peak of the Omicron surge in mid-January, when weekly cases hit 1.15 million, and they represent the lowest weekly count since mid-July of 2021. Cumulative cases in children now number close to 12.9 million over the course of the pandemic, which is 19.0% of cases among all ages, the AAP and CHA said in their weekly COVID report.

Data on new-case rates from the Centers for Disease Control and Prevention show the same continued decline, but the CDC acknowledges the possibility of reporting delays in recent weeks. The numbers for the latest week, April 3-9, maintain the larger overall decline, but there have been a couple of small, temporary increases over the last month, the CDC reported on its COVID Data Tracker.

Daily new admissions of children aged 0-17 years with confirmed COVID were right around 0.14 per 100,000 population for April 3-9, compared with 0.13 per 100,000 during the week ending April 2, the CDC said, with reporting delays making it possible that the 0.14 figure could be revised upward in the near future. The highest admission rate, 1.25 children per 100,000 population, occurred on Jan. 15 and 16.

The latest on vaccination

New vaccinations slipped a bit in the last week, with the drop slightly larger among those aged 12-17 years – from 47,000 for the week of March 24-30 to 43,000 during March 31 to April 6 – than in children aged 5-11, who went from 70,000 initial doses to 69,000 over the same 2-week period, the AAP said in its weekly report on vaccination trends.

Among the states, Vermont has fully vaccinated more children aged 5-11 (58%) than any other state, while Hawaii is the leader in fully vaccinated 12- to 17-year-olds at 86%. The lowest comparable figures for both groups can be found in Alabama, where 10% of children aged 5-11 are fully vaccinated and 34% of those aged 12-17 have received both doses of the Pfizer-BioNTech vaccine, the AAP said.

National figures show equally large COVID vaccination gaps between the two age groups. As of April 11, 68% of all children aged 12-17 years had received at least one dose, compared with 34.6% of those aged 5-11, and 58.5% of the older group was fully vaccinated, versus 28.0% of the 5- to 11-year-olds, the CDC reported.

When benzodiazepines were first introduced, they were greeted with enthusiasm. Librium came first, in 1960, followed by Valium in 1962, and they were seen as an improvement over barbiturates for the treatment of anxiety, insomnia, and seizures. From 1968 to 1982, Valium (diazepam) was the No. 1–selling U.S. pharmaceutical: 2.3 billion tablets of Valium were sold in 1978 alone. Valium was even the subject of a 1966 Rolling Stones hit, “Mother’s Little Helper.”

By the 1980s, it became apparent that there was a downside to these medications: patients became tolerant, dependent, and some became addicted to the medications. In older patients an association was noted with falls and cognitive impairment. And while safe in overdoses when they are the only agent, combined with alcohol or opioids, benzodiazepines can be lethal and have played a significant role in the current overdose crisis.

Because of the problems that are associated with their use, benzodiazepines and their relatives, the Z-drugs used for sleep, have become stigmatized, as have the patients who use them and perhaps even the doctors who prescribe them. Still, there are circumstances where patients find these medications to be helpful, where other medications don’t work, or don’t work quickly enough. They provide fast relief in conditions where there are not always good alternatives.

In the Facebook group, “Psychiatry for All Physicians,” it’s not uncommon for physicians to ask what to do with older patients who are transferred to them on therapeutic doses of benzodiazepines or zolpidem. These are outpatients coming for routine care, and they find the medications helpful and don’t want to discontinue them. They have tried other medications that were not helpful. I’ve been surprised at how often the respondents insist the patient should be told he must taper off the medication. “Just say no,” is often the advice, and perhaps it’s more about the doctor’s discomfort than it is about the individual patient. For sleep issues, cognitive-behavioral therapy is given as the gold-standard treatment, while in my practice I have found it difficult to motivate patients to engage in it, and of those who do, it is sometimes helpful, but not a panacea. Severe anxiety and sleepless nights, however, are not benign conditions.

This “just say no, hold the line” sentiment has me wondering if our pendulum has swung too far with respect to prescribing benzodiazepines. Is this just one more issue that has become strongly polarized? Certainly the literature would support that idea, with some physicians writing about how benzodiazepines are underused, and others urging avoidance.

I posted a poll on Twitter: Has the anti-benzo movement gone too far? In addition, I started a Twitter thread of my own thoughts about prescribing and deprescribing these medications and will give a synopsis of those ideas here.

Clearly, benzodiazepines are harmful to some patients, they have side effects, can be difficult to stop because of withdrawal symptoms, and they carry the risk of addiction. That’s not in question. Many medications, however, have the potential to do more harm than good, for example ibuprofen can cause bleeding or renal problems, and Fosamax, used to treat osteoporosis, can cause osteonecrosis of the jaw and femur, to name just two.

It would be so much easier if we could know in advance who benzodiazepines will harm, just as it would be good if we could know in advance who will get tardive dyskinesia or dyslipidemia from antipsychotic medications, or who will have life-threatening adverse reactions from cancer chemotherapy with no tumor response. There are risks to both starting and stopping sedatives, and if we insist a patient stop a medication because of potential risk, then we are cutting them off from being a partner in their own care. It also creates an adversarial relationship that can be draining for the doctor and upsetting for the patient.

By definition, if someone needs hospitalization for a psychiatric condition, their outpatient benzodiazepine is not keeping them stable and stopping it may be a good idea. If someone is seen in an ED for a fall, it’s common to blame the benzodiazepine, but older people who are not on these medications also fall and have memory problems. In his book, “Being Mortal: Illness, Medicine, and What Matters Most in the End” (New York: Picador, 2014), Atul Gawande, MD, makes the point that taking more than four prescriptions medications increases the risk for falls in the elderly. Still, no one is suggesting patients be taken off their antidepressants, antihypertensives, or blood thinners.

Finally, the question is not should we be giving benzodiazepines out without careful consideration – the answer is clearly no. Physicians don’t pass out benzodiazepines “like candy” for all the above reasons. They are initiated because the patient is suffering and sometimes desperate. Anxiety, panic, intractable insomnia, and severe agitation are all miserable, and alternative treatments may take weeks to work, or not work at all. Yet these subjective symptoms may be dismissed by physicians.

So what do I do in my own practice? I don’t encourage patients to take potentially addictive medications, but I do sometimes use them. I give ‘as needed’ benzodiazepines to people in distress who don’t have a history of misusing them. I never plan to start them as a permanent standing medication, though once in a while that ends up happening. As with other medications, it is best to use the minimally effective dose.

There is some controversy as to whether it is best to use anxiety medications on an “as-needed” basis or as a standing dosage. Psychiatrists who prescribe benzodiazepines more liberally often feel it’s better to give standing doses and prevent breakthrough anxiety. Patients may appear to be ‘medication seeking’ not because they are addicted, but because the doses used are too low to adequately treat their anxiety.

My hope is that there is less risk of tolerance, dependence, or addiction with less-frequent dosing, and I prescribe as-needed benzodiazepines for panic attacks, agitated major depression while we wait for the antidepressant to “kick in,” insomnia during manic episodes, and to people who get very anxious in specific situations such as flying or for medical procedures. I sometimes prescribe them for people with insomnia that does not respond to other treatments, or for disabling generalized anxiety.

For patients who have taken benzodiazepines for many years, I continue to discuss the risks, but often they are not looking to fix something that isn’t broken, or to live a risk-free life. A few of the patients who have come to me on low standing doses of sedatives are now in their 80’s, yet they remain active, live independently, drive, travel, and have busy social lives. One could argue either that the medications are working, or that the patient has become dependent on them and needs them to prevent withdrawal.

These medications present a quandary: by denying patients treatment with benzodiazepines, we are sparing some people addictions (this is good, we should be careful), but we are leaving some people to suffer. There is no perfect answer.

What I do know is that doctors should think carefully and consider the patient in front of them. “No Benzos Ever For Anyone” or “you must come off because there is risk and people will think I am a bad doctor for prescribing them to you” can be done by a robot.

So, yes, I think the pendulum has swung a bit too far; there is a place for these medications in acute treatment for those at low risk of addiction, and there are people who benefit from them over the long run. At times, they provide immense relief to someone who is really struggling.

So what was the result of my Twitter poll? Of the 219 voters, 34.2% voted: “No, the pendulum has not swung too far, and these medications are harmful”; 65.8% voted: “Yes, these medications are helpful.” There were many comments expressing a wide variety of sentiments. Of those who had taken prescription benzodiazepines, some felt they had been harmed and wished they had never been started on them, and others continue to find them helpful. Psychiatrists, it seems, see them from the vantage point of the populations they treat.

People who are uncomfortable search for answers, and those answers may come in the form of meditation or exercise, medicines, or illicit drugs. It’s interesting that these same patients can now easily obtain “medical” marijuana, and the Rolling Stones’ “Mother’s Little Helper” is often replaced by a gin and tonic.

I give ‘as needed’ benzodiazepines to people in distress who don’t have a history of misusing them. I never plan to start them as a permanent standing medication, though once in a while that ends up happening. As with other medications, it is best to use the minimally effective dose.

There is some controversy as to whether it is best to use anxiety medications on an “as-needed” basis or as a standing dosage. Psychiatrists who prescribe benzodiazepines more liberally often feel it’s better to give standing doses and prevent breakthrough anxiety. Patients may appear to be ‘medication seeking’ not because they are addicted, but because the doses used are too low to adequately treat their anxiety.

My hope is that there is less risk of tolerance, dependence, or addiction with less-frequent dosing, and I prescribe as-needed benzodiazepines for panic attacks, agitated major depression while we wait for the antidepressant to “kick in,” insomnia during manic episodes, and to people who get very anxious in specific situations such as flying or for medical procedures. I sometimes prescribe them for people with insomnia that does not respond to other treatments, or for disabling generalized anxiety.

For patients who have taken benzodiazepines for many years, I continue to discuss the risks, but often they are not looking to fix something that isn’t broken, or to live a risk-free life. A few of the patients who have come to me on low standing doses of sedatives are now in their 80’s, yet they remain active, live independently, drive, travel, and have busy social lives. One could argue either that the medications are working, or that the patient has become dependent on them and needs them to prevent withdrawal.

These medications present a quandary: by denying patients treatment with benzodiazepines, we are sparing some people addictions (this is good, we should be careful), but we are leaving some people to suffer. There is no perfect answer.

What I do know is that doctors should think carefully and consider the patient in front of them. “No Benzos Ever For Anyone” or “you must come off because there is risk and people will think I am a bad doctor for prescribing them to you” can be done by a robot.

So, yes, I think the pendulum has swung a bit too far; there is a place for these medications in acute treatment for those at low risk of addiction, and there are people who benefit from them over the long run. At times, they provide immense relief to someone who is really struggling.

So what was the result of my Twitter poll? Of the 219 voters, 34.2% voted: “No, the pendulum has not swung too far, and these medications are harmful”; 65.8% voted: “Yes, these medications are helpful.” There were many comments expressing a wide variety of sentiments. Of those who had taken prescription benzodiazepines, some felt they had been harmed and wished they had never been started on them, and others continue to find them helpful. Psychiatrists, it seems, see them from the vantage point of the populations they treat.

People who are uncomfortable search for answers, and those answers may come in the form of meditation or exercise, medicines, or illicit drugs. It’s interesting that these same patients can now easily obtain “medical” marijuana, and the Rolling Stones’ “Mother’s Little Helper” is often replaced by a gin and tonic.

Since the start of the pandemic, supply-chain problems have permeated just about every industry sector. While most of the media attention has focused on toilet paper and retail shipment delays, a darker, more sinister supply chain disruption has been unfolding, one that entails a sophisticated criminal enterprise that has been operating at scale to distribute and profit from counterfeit HIV drugs.

Recently, news has emerged – most notably in the Wall Street Journal – with reports of a Justice Department investigation into what appears to be a national drug trafficking network comprising more than 70 distributors and marketers.

The details read like a best-selling crime novel.

Since last year, authorities have seized 85,247 bottles of counterfeit HIV drugs, both Biktarvy (bictegravir 50 mg, emtricitabine 200 mg, and tenofovir alafenamide 25 mg tablets) and Descovy (emtricitabine 200 mg and tenofovir alafenamide 25 mg tablets). Law enforcement has conducted raids at 17 locations in eight states. Doctored supply chain papers have provided cover for the fake medicines and the individuals behind them.

But unlike the inconvenience of sparse toilet paper, this crime poses life-threatening risks to millions of patients with HIV who rely on Biktarvy to suppress the virus or Descovy to prevent infection from it. Even worse, some patients have been exposed to over-the-counter painkillers or the antipsychotic drug quetiapine fumarate masquerading as HIV drugs in legitimate but repurposed bottles.

Gilead Sciences (Foster City, Calif.), which manufactures both Biktarvy and Descovy, declined to comment when contacted, instead referring this news organization to previous press statements.
 

Falsified HIV medications, illicit purchases over 2 Years

On Aug. 5, 2021, Gilead first warned the public that it had become aware of tampered and counterfeit Biktarvy and Descovy tablets. In coordination with the Food and Drug Administration, it alerted pharmacies to “investigate the potential for counterfeit or tampered Gilead medication sold by [unauthorized] distributors that may be within their recent supply.”

On Jan. 19, 2022, Gilead issued a second statement outlining ongoing actions in coordination with U.S. marshals and local law enforcement to remove these illegal medications from circulation and prevent further distribution.

The timing of the most recent announcement was not accidental. The day before, a federal judge serving the U.S. District Court for the Eastern District of New York unsealed documents detailing the company’s lawsuit against dozens of individuals and entities who they alleged had engaged in a highly coordinated effort to defraud pharmacies and consumers. The suit followed two prior Gilead filings that ultimately resulted in court-issued ex parte seizure orders (orders that allow a court to seize property without the property owner’s consent) and the recovery of more than 1,000 bottles containing questionable Gilead medications.

The lawsuit centered on Cambridge, Mass.–based wholesale pharmaceutical distributor Safe Chain Solutions and its two cofounders. The document is peppered with terms such as “shifting series of fly-by-night corporate entities,” “gray market” distributors, a “dedicated sales force,” and “shell entities,” along with accusations that the defendants were believed to have made purchases of gold bullion, jewelry, and other luxury items for conversion into cash.

In a curious twist of fate, this sinister effort appeared to have been first revealed not by a pharmacist but by a patient who had returned a bottle of Biktarvy with “foreign medication inside” to the California pharmacy that dispensed it.

“Specifically with HIV medications, there’s no point in which the pharmacy is actually opening the bottle, breaking the seal, and counting out pills to put into a smaller prescription bottle,” Emily Heil, PharmD, BCIDP, AAHIVP, associate professor of infectious diseases in the department of pharmacy practice and science at the University of Maryland School of Pharmacy, Baltimore, told this news organization.

“But that’s also why pharmacies work with these centralized groups of distributors that maintain a chain of command and fidelity with drug manufacturers so that we don’t run into these situations,” she said.

This is the link in the chain where that tightly coordinated and highly regulated process was broken.

Although Gilead and Safe Chain Solutions were informed of the incident as early as August 2020, the distributor repeatedly refused to identify the supplier and the pedigree (the record demonstrating the chain of all sales or transfers of a specific drug, going back to the manufacturer, as required by the FDA’s Drug Supply Chain Security Act in 2013).

Later that year, Janssen Pharmaceutical Companies of Johnson & Johnson issued a media statement saying that they had been alerted to the distribution of counterfeit Symtuza (darunavir/cobicistat/emtricitabine/tenofovir alafenamide) to three pharmacies in the United States.

A spokesperson for the FDA declined to comment on the ongoing investigation when contacted by this news organization and instead wrote in an email that the agency “will continue to use all available tools to ensure consumers and patients have access to a safe and effective medical product supply.”
 

Old dog, new tricks

This is not the first time that HIV drugs have been targeted for criminal benefit. An analysis published in September 2014 in JAMA highlighted a federal investigation that year into a $32 million dollar scheme to defraud Medicare’s Part D program for HIV drugs and divert them for resale on the black market.

What’s more, prior research and news reports highlight the attractiveness of HIV drug diversion both for the buyer and the seller – not only because of the cost of the drugs themselves but also because of institutional or systemic deficiencies that exclude certain individuals from obtaining treatment through federal initiatives such as the Ryan White/AIDS Drug Assistance program.

In its most recent statement, Gilead reinforced that this practice remains alive and well.

On the buyer side, the company stated, many of the counterfeits originated from suppliers who purchased Gilead HIV medication from individuals after it was first dispensed to them. Unfortunately, the exploitation of individuals with low incomes who experience homelessness or substance use/abuse echoes a pattern whereby HIV patients sell medications to cover personal needs or are forced to buy them on the black market to keep up with their treatment regimens.

On the supply side, Gilead explained that individuals’ medications “are unlawfully resold ... on the secondary market by way of counterfeit supply chain documentation, concealing and fraudulently misrepresenting its origin. All of these counterfeits were sold as though they were legitimate Gilead products.”

But counterfeit pedigrees make it impossible to verify where the products came from, how they have been handled and stored, and what pills are in the bottles – all of which can have dire consequences for patients who ingest them.

The ramifications can be devastating.

“With HIV meds specifically, the worst case scenario would be if the medication is not actually the medication they’re supposed to be on,” said Dr. Heil, reinforcing that the increased safety net provided with viral suppression and against transmission is lost.

Dr. Heil pointed to another significant risk: resistance.

“In a situation like this, where maybe it’s not the full strength of the medication, maybe it’s expired and lost potency or was not stored correctly or is not even the accurate medication, changing those drug level exposures potentially puts the patient at risk for developing resistance to their regimen without them knowing.”

Yet another risk was posed by the replacement of HIV drugs with other medications, such as quetiapine, which increased the risk for life-threatening and irreversible side effects. The lawsuit included a story of a patient who unknowingly took quetiapine after receiving a counterfeit bottle of Biktarvy and could not speak or walk afterward.

Where this tale will ultimately end is unclear. There’s no telling what other activities or bad actors the Justice Department investigation will uncover as it works to unravel the counterfeit network’s activities and deal with its aftermath.

Regardless, clinicians are encouraged to inform HIV patients about the risks associated with counterfeit medications, how to determine whether the drugs they’ve been dispensed are authentic, and to report any product they believe to be counterfeit or to have been tampered with to their doctors, pharmacies, and to Gilead or other drug manufacturers.

“It’s okay to ask questions of your pharmacy about where they get their medications from,” noted Dr. Heil. “If patients have access to an independent pharmacy, it’s a great way for them to have a relationship with their pharmacist.

“We went into this profession to be able to have those conversations with patients,” Dr. Heil said.

The FDA recommends that patients receiving these medications who believe that their drugs may be counterfeit or who experience any adverse effects report the event to FDA’s MedWatch Safety Information and Adverse Event Reporting Program (1-800-FDA-1088 or www.fda.gov/medwatch).

Dr. Heil reported having no relevant financial relationships.

A popular fitness tracker company has received approval from the Food and Drug Administration for a new software algorithm to detect atrial fibrillation (AFib), Fitbit announced on April 11.

The algorithm will be the basis of an upcoming Fitbit feature called Irregular Heart Rhythm Notifications, the company said in a press release.

The approval was based on data from the Fitbit Heart Study, which was conducted entirely virtually in more than 455,000 U.S. adults. Participants who had an irregular heart rhythm detected by the software algorithm were notified and invited to meet with a telehealth doctor. They then received a 1-week ECG patch monitor to wear along with the smartwatch or fitness tracker.

Results, presented at the annual scientific sessions of the American Heart Association in November 2021, showed that the positive predictive value of the Fitbit algorithm for detecting undiagnosed AFib with a range of wearable devices was 98%. Notably, irregular heart rhythm detection occurred in 1% of participants overall and 4% of those older than 65 years.

The algorithm works by using an optical measurement method called photoplethysmography (PPG), along with heart rate input from the Fitbit’s photodetector device.

It operates only when the user is still or at rest, so overnight use is important for detection, the company noted.

The upcoming Irregular Heart Rhythm Notifications feature will complement the existing ECG app, providing two ways to detect AFib. The ECG app provides a “spot-check approach” in which the users can screen themselves, and the PPG-based feature will allow for long-term heart rhythm assessment, the statement explained.

“Undiagnosed atrial fibrillation can lead to strokes, and early detection of atrial fibrillation may allow doctors to prescribe medications that are effective at preventing strokes,” said Steven A. Lubitz, MD, MPH, a cardiologist at Harvard University and Massachusetts General Hospital, both in Boston, at the AHA meeting.

What causes the dramatic alterations in subjective awareness experienced during a psychedelic “trip?” A new study maps anatomical changes in specific neurotransmitter systems and brain regions that may be responsible for these effects.

Investigators gathered more than 6,800 accounts from individuals who had taken one of 27 different psychedelic compounds. Using a machine learning strategy, they extracted commonly used words from these testimonials, linking them with 40 different neurotransmitter subtypes that had likely induced these experiences.

The investigators then linked these subjective experiences with specific brain regions where the receptor combinations are most commonly found and, using gene transcription probes, created a 3D whole-brain map of the brain receptors and the subjective experiences linked to them.

“Hallucinogenic drugs may very well turn out to be the next big thing to improve clinical care of major mental health conditions,” senior author Danilo Bzdok, MD, PhD, associate professor, McGill University, Montreal, said in a press release.

“Our study provides a first step, a proof of principle, that we may be able to build machine-learning systems in the future that can accurately predict which neurotransmitter receptor combinations need to be stimulated to induce a specific state of conscious experience in a given person,” said Dr. Bzdok, who is also the Canada CIFAR AI Chair at Mila-Quebec Artificial Intelligence Institute.

The study was published online  in Science Advances.
 

‘Unique window’

Psychedelic drugs “show promise” as treatments for various psychiatric disorders, but subjective alterations of reality are “highly variable across individuals” and this “poses a key challenge as we venture to bring hallucinogenic substances into medical practice,” the investigators note.

Although the 5-HT2A receptor has been regarded as a “putative essential mechanism” of hallucinogenic experiences, it is unclear whether the experiential differences are explained by functional selectivity at the 5-HT2A receptor itself or “orchestrated by the vast array of neurotransmitter receptor subclasses on which these drugs act,” they add.

Lead author Galen Ballentine, MD, psychiatry resident, SUNY Downstate Medical Center, Brooklyn, told this news organization that he was “personally eager to find novel ways to identify the neurobiological underpinnings of different states of conscious awareness.”

Psychedelics, he said, offer a “unique window into a vast array of unusual states of consciousness and are particularly useful because they can point toward underlying mechanistic processes that are initiated in specific areas of receptor expression.”

The investigators wanted to understand “how these drugs work in order to help guide their use in clinical practice,” Dr. Ballentine said.

To explore the issue, they undertook the “largest investigation to date into the neuroscience of psychedelic drug experiences,” Dr. Ballentine said. “While most studies are limited to a single drug on a handful of subjects, this project integrates thousands of experiences induced by dozens of different hallucinogenic compounds, viewing them through the prism of 40 receptor subtypes.”
 

Unique neurotransmitter fingerprint

The researchers analyzed 6,850 experience reports of people who had taken 1 of 27 psychedelic compounds. The reports were drawn from a database hosted by the Erowid Center, an organization that collects first-hand accounts of experiences elicited by psychoactive drugs.

The researchers constructed a “bag-of-words” encoding of the text descriptions in each testimonial. Using linguistic calculation methods, they derived a final vocabulary of 14,410 words that they analyzed for descriptive experiential terms.

To shed light on the spatial distribution of these compounds that modulate neuronal activity during subjective “trips,” they compared normalized measurements of their relative binding strengths in 40 sites.

• 5-HT (5-HT2A, 5-HT2C, 5-HT2B, 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E, 5-HT5A, 5-HT6, 5-HT7)
• Dopamine (D1, D2, D3, D4, D5)
• Adrenergic (a-1A, a-1B, a-2A, a-2B, a-2C, b-1, b-2)
• Serotonin transporter (SERT)
• Dopamine transporter (DAT)
• Norepinephrine transporter (NET)
• Imidazoline-1 receptor (I1)
• Sigma receptors (s-1, s-2)
• d-opioid receptor (DOR)
• k-opioid receptor (KOR)
• m-opioid receptor (MOR)
• Muscarinic receptors (M1, M2, M3, M4, M5)
• Histamine receptors (H1, H2)
• Calcium ion channel (CA+)
• NMDA glutamate receptor

To map receptor-experience factors to regional levels of receptor gene transcription, they utilized human gene expression data drawn from the Allen Human Brain Atlas, as well as the Shafer-Yeo brain atlas.

Via a machine-learning algorithm, they dissected the “phenomenologically rich anecdotes” into a ranking of constituent brain-behavior factors, each of which was characterized by a “unique neurotransmitter fingerprint of action and a unique experiential context” and ultimately created a dimensional map of these neurotransmitter systems.
 

Data-driven framework

Cortex-wide distribution of receptor-experience factors was found in both deep and shallow anatomical brain regions. Regions involved in genetic factor expressions were also wide-ranging, spanning from higher association cortices to unimodal sensory cortices.

The dominant factor “elucidated mystical experience in general and the dissolution of self-world boundaries (ego dissolution) in particular,” the authors report, while the second- and third-most explanatory factors “evoked auditory, visual, and emotional themes of mental expansion.”

Ego dissolution was found to be most associated with the 5-HT2A receptor, as well as other serotonin receptors (5-HT2C, 5-HT1A, 5-HT2B), adrenergic receptors a-2A and b-2, and the D2 receptor.

Alterations in sensory perception were associated with expression of the 5-HT2A receptor in the visual cortex, while modulation of the salience network by dopamine and opioid receptors were implicated in the experience transcendence of space, time, and the structure of self. Auditory hallucinations were linked to a weighted blend of receptors expressed throughout the auditory cortex.

“This data-driven framework identifies patterns that undergird diverse psychedelic experiences such as mystical bliss, existential terror, and complex hallucinations,” Dr. Ballentine commented.

“Simultaneously subjective and neurobiological, these patterns align with the leading hypothesis that psychedelics temporarily diminish top-down control of the most evolutionarily advanced regions of the brain, while at the same time amplifying bottom-up sensory processing from primary sensory cortices,” he added.
 

Forging a new path

Scott Aaronson, MD, chief science officer, Institute for Advanced Diagnostics and Therapeutics and director of the Centre of Excellence at Sheppard Pratt, Towson, Md., said, “As we try to get our arms around understanding the implications of a psychedelic exposure, forward-thinking researchers like Dr. Bzdok et al. are offering interesting ways to capture and understand the experience.”

Dr. Aaronson, an adjunct professor at the University of Maryland School of Medicine who was not involved with the study, continued: “Using the rapidly developing field of natural language processing (NLP), which looks at how language is used for a deeper understanding of human experiences, and combining it with effects of psychedelic compounds on neuronal pathways and neurochemical receptor sites, the authors are forging a new path for further inquiry.” 

In an accompanying editorial, Daniel Barron, MD, PhD, medical director, Interventional Pain Psychiatry Program, Brigham and Women’s Hospital, Boston, and Richard Friedman, MD, professor of clinical psychiatry, Weill Cornell Medical College, New York, call the work “impressive” and “clever.”

“Psychedelics paired with new applications of computational tools might help bypass the imprecision of psychiatric diagnosis and connect measures of behavior to specific physiologic targets,” they write.
