Goodbye ‘diabetes insipidus’, hello ‘AVP-D’ and ‘AVP-R’

An international group representing leading endocrinology associations has recommended that the name “diabetes insipidus” – which in some cases has led to harm – be changed to eliminate confusion with “diabetes mellitus” and to reflect the former condition’s pathophysiology.

The new proposed names are arginine vasopressin deficiency (AVP-D) for central (also called “cranial”) etiologies and arginine vasopressin resistance (AVP-R) for nephrogenic (kidney) etiologies.

“What we’re proposing is to rename the disease according to the pathophysiology that defines it,” statement co-author Joseph G. Verbalis, MD, professor of medicine and chief of endocrinology and metabolism at Georgetown University Medical Center, Washington, told this news organization.

The statement advises that henceforth the new names be used in manuscripts and the medical literature while keeping the old names in parentheses during a transition period, as in “AVP-deficiency (cranial diabetes insipidus)” and “AVP-resistance (nephrogenic diabetes insipidus).”

The condition formerly known as diabetes insipidus is relatively rare, occurring in about 1 person per 10-15,000 population. It is caused by either deficient production or resistance in the kidney to the hormone AVP, normally produced by the hypothalamus and stored in the pituitary gland. AVP, also called antidiuretic hormone, regulates the body’s water level and urine production by the kidney.

Both etiologies lead to extreme thirst and excessive production of urine. Common causes of the deficiency include head trauma or brain tumor, while resistance in the kidney is often congenital. It is currently treated with a synthetic form of AVP called desmopressin and fluid replacement.
 

What’s in a name?

The proposal to change the name by the Working Group for Renaming Diabetes Insipidus is endorsed by The Endocrine Society, European Society of Endocrinology, Pituitary Society, Society for Endocrinology, European Society for Paediatric Endocrinology, Endocrine Society of Australia, Brazilian Endocrine Society, and Japanese Endocrine Society and is under review by several other societies. It was published as a position statement in several of those society’s journals, with more to follow.

Historically, the word “diabetes,” a Greek word meaning “siphon,” was used in the 1st and 2nd century BC to describe excess flow of urine. The Latin word “mellitus” or “honey” was added in the late 17th century to describe the sweetness of the urine in the dysglycemic condition.

A century later, the Latin word “insipidus,” meaning insipid or tasteless, was coined to distinguish between the two types of polyuria, the position statement details.

In the late 19th to early 20th century, the vasopressor and antidiuretic actions of posterior pituitary extracts were discovered and used to treat people with both the central and nephrogenic etiologies, which were also recognized around that time, yet the name “diabetes insipidus” has persisted.

“From a historical perspective, the name is perfectly appropriate. At the time it was identified, and it was realized that it was different from diabetes mellitus, that was a perfectly appropriate terminology based on what was known in the late 19th century – but not now. It has persisted through the years simply because in medicine there’s a lot of inertia for change ... It’s just always been called that. If there’s not a compelling reason to change a name, generally there’s no move to change it,” Dr. Verbalis observed.  
 

 

 

‘Dramatic cases of patient mismanagement’ due to name confusion

Unfortunately, the urgency for the change arose from tragedy. In 2009, a 22-year-old man was admitted to the orthopedics department of a London teaching hospital for a hip replacement. Despite his known panhypopituitarism and diabetes insipidus, the nurses continually checked his blood glucose but didn’t give him desmopressin or sufficient fluids. Laboratory testing showed normal glucose, but his serum sodium was 149 mmol/L. The morning after his operation, he had a fatal cardiac arrest with a serum sodium of 169 mmol/L. 

“The nurses thought he had diabetes mellitus ... So that was death due to failure to recognize that diabetes insipidus is not diabetes mellitus,” Dr. Verbalis said. “If he had been admitted to endocrinology, this wouldn’t have happened. But he was admitted to orthopedics. Non-endocrinologists are not so aware of diabetes insipidus, because it is a rare disease.”

In 2016, National Health Service England issued a patient safety alert about the “risk of severe harm or death when desmopressin is omitted or delayed in patients with cranial diabetes insipidus,” citing at least four incidents within the prior 7 years where omission of desmopressin had resulted in severe dehydration and death, with another 76 cases of omission or delay that were acted on before the patients became critically ill.

Further impetus for the name change came from the results of an anonymous web-based survey of 1,034 adult and pediatric patients with central diabetes insipidus conducted between August 2021 and February 2022. Overall, 80% reported encountering situations in which their condition had been confused with diabetes mellitus by health care professionals, and 85% supported renaming the disease.

There was some divergence in opinion as to what the new name(s) should be, but clear agreement that the term “diabetes” should not be part of it.  

“We’ve only become recently aware that there are dramatic cases of patient mismanagement due to the confusion caused by the word ‘diabetes.’ We think patients should have a voice. If a legitimate patient survey says over 80% think this name should be changed, then I think we as endocrinologists need to pay attention to that,” Dr. Verbalis said.

But while endocrinologists are the ones who see these patients the most often, Dr. Verbalis said a main aim of the position statement “is really to change the mindset of non-endocrinologist doctors and nurses and other health care professionals that this is not diabetes mellitus. It’s a totally different disease. And if we give it a totally different name, then I think they will better recognize that.”

As to how long Dr. Verbalis thinks it will take for the new names to catch on, he pointed out that it’s taken about a decade for the rheumatology field to fully adopt the name “granulomatosis with polyangiitis” as a replacement for “Wegener’s granulomatosis” after the eponymous physician’s Nazi ties were revealed.

“So we’re not anticipating that this is going to change terminology tomorrow. It’s a long process. We just wanted to get the process started,” he said.

Dr. Verbalis has reported consulting for Otsuka.

Two-year dupilumab data: Continued response for moderate to severe pediatric asthma

. – For children with uncontrolled asthma on standard therapies and meeting criteria of a type 2 (T2) inflammatory phenotype, a prospective 1-year extension from a phase 3 trial supports the biologic dupilumab as a potential treatment standard, according to the investigator who presented the findings at the annual meeting of the American College of Chest Physicians (CHEST).

“The appropriate candidate is a child with the T2 inflammatory phenotype who is still experiencing exacerbations on at least a medium dose of inhaled corticosteroids plus a second controller medication,” said Leonard B. Bacharier, MD, section chief, division of pediatric allergy, immunology, and pulmonary medicine, Vanderbilt University Medical Center, Nashville, Tenn.

By T2 inflammatory phenotype, Dr. Bacharier specified that key features include an eosinophil count of at least 150 cells/mL and a FENO level of at least 20 ppb. If children meet these and inadequate standard-therapy response criteria, Dr. Bacharier thinks the extension data support dupilumab as a routine therapy despite the cost.

“As a pediatrician, I think it is really important that children with asthma finish their childhood with the best bone health and the lowest risk of other steroid-associated adverse events,” Dr. Bacharier said.

Over the course of the 1-year extension, called EXCURSION, there was no evidence of diminished efficacy nor of any new safety signal. In other words, patients have remained well controlled for 2 years with a well-tolerated therapy. Dr. Bacharier pointed out, however, that one of the most compelling reasons to consider this as a potential standard was the very low rates at which patients required a course of steroids.

At the end of 1 year in the extension trial, called VOYAGE, the unadjusted annualized total number of steroid courses per patient was 0.414 in the dupilumab group vs. 0.816 in the placebo group. At the end of EXCURSION, following an additional year of therapy, the rate was 0.152.

“This means that fewer than 2 patients out of 10 required prednisone in the previous year,” Dr. Bacharier said.

The EXCURSION extension study did not capture data on steroid-related adverse events, but Dr. Bacharier said that these data are reassuring for both acute and long-term risks of steroid exposure.

“We know that the adverse effects associated with oral steroids are related to cumulative exposure. The more you receive, the greater the risk of adverse effects,” he said.

In patients who were randomly assigned to placebo in the VOYAGE trial and then switched to dupilumab in the EXCURSION extension, steroid exposure was also very low, but whether evaluated as annualized total courses (0.152 vs. 0.181) or by proportion of patients with any steroid intake (10.5% vs. 13.2%), there was a numerical advantage for starting and remaining on dupilumab over the 2-year follow-up.

In VOYAGE, which was published last year in the New England Journal of Medicine, 408 children from ages 6 to 11 years were randomly assigned in a 2:1 ratio to dupilumab or matching placebo. For children weighing less than 30 kg, the dose was 200 mg. For those who weighed less, the dose was 100 mg. Both doses were administered every 2 weeks.

As previously reported, the study met the primary endpoint of annualized rate of severe asthma exacerbations, which was 0.31 in the dupilumab group vs. 0.75 in the placebo group, a relative reduction of 59.3% (P < .001). Dupilumab was also superior on several secondary endpoints, including measures of lung function and asthma control.

The EXCURSION extension study enrolled 365 of the patients who participated in VOYAGE. This included 125 of the 135 randomly assigned to placebo and 240 of the 273 randomly assigned to dupilumab. Those initially randomly assigned to placebo were transitioned to dupilumab. The same weight-based dosing was employed.

At baseline, the children enrolled in VOYAGE had an annualized rate of 2.560 severe exacerbations. At the end of VOYAGE, this rate was 0.330. At the end of EXCURSION after 2 years on dupilumab, the rate was 0.118. In the group switched from placebo to dupilumab, the rate was 0.124.

During EXCURSION, treatment-emergent adverse events occurred in 2.5% of those who remained on dupilumab and 0.8% of those switched from placebo to dupilumab. Three patients (1.3%) permanently discontinued therapy because of a treatment-related event. The most common adverse events involved upper respiratory complaints, such as nasopharyngitis, pharyngitis, upper respiratory tract infections, and rhinitis influenza, but all were reported in fewer than 10% of patients. Other reported side effects, such as injection-site reactions and diarrhea, occurred in 5% or fewer of patients.

“Over the 2 years, dupilumab was well tolerated, and there was evidence of an increased risk of adverse events for longer exposure,” Dr. Bacharier reported.

It is for this reason that Dr. Bacharier concluded that children with repeated exacerbations requiring steroids despite standard therapies should be considered for dupilumab if they also meet criteria for the T2 inflammatory phenotype. This last point is important.

“In children with low levels of eosinophil and low phenol, we are not seeing these kinds of response,” Dr. Bacharier said. Rather, in the absence of eosinophilia, “there is probably no difference between dupilumab and placebo.”

An important steroid-sparing effect is “suggested” by the data, but Sally E. Wenzel, MD, director of the University of Pittsburgh Asthma and Environmental Lung Health Institute in Pittsburgh, characterized the idea that dupilumab is emerging to be a standard in uncontrolled asthma in children with the T2 phenotype as “a bit premature.”

She challenged the conclusion that the EXCURSION data associated dupilumab with a reduction in annualized steroid courses over time. While the number was lower after 2 years of treatment than after 1, Dr. Wenzel pointed out that all patients were on dupilumab in the second year, “so we don’t know what really happens without treatment.” She said there are other potential explanations, including the possibility that aging children have less active disease.

More importantly, Dr. Wenzel said in an interview that she would also hesitate to urge biologics in every child who meets the criteria that Dr. Bacharier outlined.

“The most important concern is that we do not know how long one should continue the dupilumab and if the long-term treatment adversely or positively affects a growing immune system,” she said.

There is reason to be concerned that blockage of an entire immune pathway with a biologic could adversely affect autoimmunity as well as susceptibility to cancer, according to Dr. Wenzel. She hopes this does not prove to be the case, but she encouraged prudence until there are more data to judge.

While extension data for dupilumab “sound good,” she thinks moving toward any type of standard of care with biologics in children “has to be done with caution and constant evaluation and reevaluation.”

Dr. Bacharier disclosed relationships with AstraZeneca, GlaxoSmithKline, Regeneron and Sanofi. The two latter companies collaborated on the development and marketing of dupilumab. Dr. Wenzel disclosed relationships with AstraZeneca, GlaxoSmithKline, Knopp Pharmaceuticals, Pieris, and Sanofi-Regeneron.

While the number was lower after 2 years of treatment than after 1, Dr. Wenzel pointed out that all patients were on dupilumab in the second year, “so we don’t know what really happens without treatment.” She said there are other potential explanations, including the possibility that aging children have less active disease.

More importantly, Dr. Wenzel said in an interview that she would also hesitate to urge biologics in every child who meets the criteria that Dr. Bacharier outlined.

“The most important concern is that we do not know how long one should continue the dupilumab and if the long-term treatment adversely or positively affects a growing immune system,” she said.

There is reason to be concerned that blockage of an entire immune pathway with a biologic could adversely affect autoimmunity as well as susceptibility to cancer, according to Dr. Wenzel. She hopes this does not prove to be the case, but she encouraged prudence until there are more data to judge.

While extension data for dupilumab “sound good,” she thinks moving toward any type of standard of care with biologics in children “has to be done with caution and constant evaluation and reevaluation.”

Dr. Bacharier disclosed relationships with AstraZeneca, GlaxoSmithKline, Regeneron and Sanofi. The two latter companies collaborated on the development and marketing of dupilumab.

. – For children with uncontrolled asthma on standard therapies and meeting criteria of a type 2 (T2) inflammatory phenotype, a prospective 1-year extension from a phase 3 trial supports the biologic dupilumab as a potential treatment standard, according to the investigator who presented the findings at the annual meeting of the American College of Chest Physicians (CHEST).

“The appropriate candidate is a child with the T2 inflammatory phenotype who is still experiencing exacerbations on at least a medium dose of inhaled corticosteroids plus a second controller medication,” said Leonard B. Bacharier, MD, section chief, division of pediatric allergy, immunology, and pulmonary medicine, Vanderbilt University Medical Center, Nashville, Tenn.

By T2 inflammatory phenotype, Dr. Bacharier specified that key features include an eosinophil count of at least 150 cells/mL and a FENO level of at least 20 ppb. If children meet these and inadequate standard-therapy response criteria, Dr. Bacharier thinks the extension data support dupilumab as a routine therapy despite the cost.

“As a pediatrician, I think it is really important that children with asthma finish their childhood with the best bone health and the lowest risk of other steroid-associated adverse events,” Dr. Bacharier said.

Over the course of the 1-year extension, called EXCURSION, there was no evidence of diminished efficacy nor of any new safety signal. In other words, patients have remained well controlled for 2 years with a well-tolerated therapy. Dr. Bacharier pointed out, however, that one of the most compelling reasons to consider this as a potential standard was the very low rates at which patients required a course of steroids.

At the end of 1 year in the extension trial, called VOYAGE, the unadjusted annualized total number of steroid courses per patient was 0.414 in the dupilumab group vs. 0.816 in the placebo group. At the end of EXCURSION, following an additional year of therapy, the rate was 0.152.

“This means that fewer than 2 patients out of 10 required prednisone in the previous year,” Dr. Bacharier said.

The EXCURSION extension study did not capture data on steroid-related adverse events, but Dr. Bacharier said that these data are reassuring for both acute and long-term risks of steroid exposure.

“We know that the adverse effects associated with oral steroids are related to cumulative exposure. The more you receive, the greater the risk of adverse effects,” he said.

In patients who were randomly assigned to placebo in the VOYAGE trial and then switched to dupilumab in the EXCURSION extension, steroid exposure was also very low, but whether evaluated as annualized total courses (0.152 vs. 0.181) or by proportion of patients with any steroid intake (10.5% vs. 13.2%), there was a numerical advantage for starting and remaining on dupilumab over the 2-year follow-up.

In VOYAGE, which was published last year in the New England Journal of Medicine, 408 children from ages 6 to 11 years were randomly assigned in a 2:1 ratio to dupilumab or matching placebo. For children weighing less than 30 kg, the dose was 200 mg. For those who weighed less, the dose was 100 mg. Both doses were administered every 2 weeks.

As previously reported, the study met the primary endpoint of annualized rate of severe asthma exacerbations, which was 0.31 in the dupilumab group vs. 0.75 in the placebo group, a relative reduction of 59.3% (P < .001). Dupilumab was also superior on several secondary endpoints, including measures of lung function and asthma control.

The EXCURSION extension study enrolled 365 of the patients who participated in VOYAGE. This included 125 of the 135 randomly assigned to placebo and 240 of the 273 randomly assigned to dupilumab. Those initially randomly assigned to placebo were transitioned to dupilumab. The same weight-based dosing was employed.

At baseline, the children enrolled in VOYAGE had an annualized rate of 2.560 severe exacerbations. At the end of VOYAGE, this rate was 0.330. At the end of EXCURSION after 2 years on dupilumab, the rate was 0.118. In the group switched from placebo to dupilumab, the rate was 0.124.

During EXCURSION, treatment-emergent adverse events occurred in 2.5% of those who remained on dupilumab and 0.8% of those switched from placebo to dupilumab. Three patients (1.3%) permanently discontinued therapy because of a treatment-related event. The most common adverse events involved upper respiratory complaints, such as nasopharyngitis, pharyngitis, upper respiratory tract infections, and rhinitis influenza, but all were reported in fewer than 10% of patients. Other reported side effects, such as injection-site reactions and diarrhea, occurred in 5% or fewer of patients.

“Over the 2 years, dupilumab was well tolerated, and there was evidence of an increased risk of adverse events for longer exposure,” Dr. Bacharier reported.

It is for this reason that Dr. Bacharier concluded that children with repeated exacerbations requiring steroids despite standard therapies should be considered for dupilumab if they also meet criteria for the T2 inflammatory phenotype. This last point is important.

“In children with low levels of eosinophil and low phenol, we are not seeing these kinds of response,” Dr. Bacharier said. Rather, in the absence of eosinophilia, “there is probably no difference between dupilumab and placebo.”

An important steroid-sparing effect is “suggested” by the data, but Sally E. Wenzel, MD, director of the University of Pittsburgh Asthma and Environmental Lung Health Institute in Pittsburgh, characterized the idea that dupilumab is emerging to be a standard in uncontrolled asthma in children with the T2 phenotype as “a bit premature.”

She challenged the conclusion that the EXCURSION data associated dupilumab with a reduction in annualized steroid courses over time.

Life expectancy 6.3 years shorter for Black MSM with HIV

Article Type
Changed
Tue, 10/25/2022 - 11:31

The life expectancy of non-Hispanic Black men who have sex with men (MSM) and are infected with HIV lags their White counterparts by 6.3 years under standard HIV care, new data from simulation modeling suggest.

Lead author Katherine Rich, MPH, a student at Harvard Medical School, Boston, presented the data during an annual scientific meeting on infectious diseases.

“Substantial disparities in care exist between Black and White MSM here in the United States,” she said. “The 2030 goals of the EHE [Ending the HIV Epidemic in the U.S. initiative] won’t be met until HIV-related disparities are reduced.”

Using modeling, the team was able to measure both the gaps and the potential of interventions to address those gaps.

  • The team found that improving engagement in care had the largest benefit in narrowing the gap. Improving engagement and retention in care, they write, would result in a gain of 1.4 life-years for Black MSM and 1 year for White MSM.
  • Annual testing would add 0.6 life-years for Black MSM and 0.3 life-years for White MSM, compared with standard care.
  • In simulating viral suppression, the model-predicted gain would be 1.1 years for Black MSM and 0.3 for White.

Furthermore, a combination of annual testing, 95% engagement in care, and 95% virologic suppression would add 3.4 years for Black MSM (more than double the increase in life-years for any one intervention) and 1.6 years for their White counterparts, the research suggests.

The researchers projected life expectancy from age 15 to be 52.2 years for Black MSM (or 67.2 years old) and 58.5 years from age 15 for White MSM (or 73.5 years old), a difference of 6.3 years.

Kathleen McManus, MD, assistant professor of medicine in infectious diseases and international health at the University of Virginia, Charlottesville, said in an interview that the projected gap in years of life should be a call to action. Dr. McManus was not involved with the study.
 

Life expectancy gap ‘alarming’

“It is alarming that with current usual HIV care Black MSM with HIV have 6.3 fewer years of life expectancy than White MSM,” she said. “Black MSM having lower retention in care and a lower rate of viral suppression than White MSM demonstrates that there is a problem with our current health care delivery to Black MSM.”

With qualitative, community-engaged research, she said, “we need to ask the Black MSM community what care innovations they need – and then we need clinics and organizations to make the identified changes.”

Researchers used the validated CEPAC (Cost-Effectiveness of Preventing AIDS Complications) microsimulation HIV model to project life expectancy. Using data from the United States Centers for Disease Control and Prevention, they estimated the average age at HIV infection to be 26.8 years for Black MSM and 35 years for White MSM.

They estimated the proportion of time that MSM with diagnosed HIV are retained in care to be 75.2% for Black MSM and 80.6% for White MSM. They calculated the proportion who achieve virologic suppression to be 82% for Black MSM and 91.2% for White MSM.

Senior author Emily P. Hyle, MD, associate professor of medicine at Harvard and infectious diseases physician at Massachusetts General Hospital, both in Boston, said in a press conference before the presentation that strategies to narrow the gap will look different by region.

“Our study highlights that if you can find effective interventions, the effect can be incredibly large. These are very large differences in life-years and life expectancies,” she said.

Ms. Rich gave an example of promising interventions by pointing to work by study coauthor Aima Ahonkhai, MD, MPH, assistant professor of medicine at Vanderbilt University, Nashville, Tenn., who has received federal funding to pursue research on whether preventive care outreach in barbershops can improve prevention for Black men with HIV.

Ms. Rich noted that the modeling has limitations in that it focused on health outcomes and did not simulate transmissions. Results also reflect national data and not local HIV care continuums, which, she acknowledged, differ substantially.

Dr. McManus and the study authors have reported no relevant financial relationships.

Achieving diversity, equity and inclusion: Invite everyone and build a team

Article Type
Changed
Wed, 10/26/2022 - 11:14

What you really don’t want to do, if you want to improve diversity, equity, and inclusion (DEI) at your academic institution, is to recruit diverse people to your program and then have them come and feel not included, said Vivian Asare, MD. “That can work against your efforts,” she stated in an oral presentation at the annual meeting of the American College of Chest Physicians (CHEST). Dr. Asare is assistant professor and vice chief of DEI for Yale Pulmonary, Critical Care, and Sleep Medicine, and associate medical director of Yale Centers for Sleep Medicine, New Haven, Conn.

In offering a path to successful DEI, Dr. Asare said: “The first step is to build a team and discuss your mission. Invite everyone to participate and include your leadership because they’re the ones who set the stage, ensure sustainability, and can be a liaison with faculty.” Then a DEI leader should be elected, she added.

The next and very important step is to survey the current institutional climate. “You need to tap into how people feel about DEI in your program.” That entails speaking directly with the stakeholders (faculty, staff, trainees) and identifying their specific concerns and what they think is lacking. Retreats, serious group discussions, and self-reflecting (asking “what initiatives would be good for us?”), and meeting one-on-one with individuals for a truly personalized approach are among potentially productive strategies for identifying the priorities and DEI-related topics specific to a particular academic sleep program.

Dr. Asare offered up a sample DEI survey (Am J Obstet Gynecol. 2020 Nov;223[5]:715.e1-715.e7), that made direct statements inviting the respondent to check off one of the following responses: Yes, No, Somewhat, Do not know, and Not applicable. Among sample statements:

  • Our department is actively committed to issues of diversity, equity, and inclusion.
  • Faculty searches in the department regularly attract a diverse pool of highly qualified candidates and/or attract a pool that represents the availability of MDs in this field.
  • Our outreach and recruitment processes employ targeted practices for attracting diverse populations.

Dr. Asare said that a survey can be a simple approach for garnering information that can be useful for prioritizing DEI topics of concern and igniting interest in them. Engagement requires regular DEI committee meetings with minutes or a newsletter and with updates and topics brought to faculty meetings.
 

Key DEI areas of focus

Dr. Asare listed several key DEI areas: Recruitment/retention, mentorship, scholarship, and inclusion and community engagement. Under scholarship, for example, she cited topics for potential inclusion in a DEI curriculum: Unconscious bias and anti-racism training, racism, discrimination and microaggression education (bystander/deescalation training), cultural competency and awareness, workplace civility, and health disparities. “We all know that implicit bias in providers is a reality, unfortunately,” Dr. Asare said. Being aware of these implicit biases is a start, but instruction on how to actively overcome them has to be provided. Tools may include perspective-taking, exploring common identity, and self-reflection.

To create an inclusive environment for all faculty, trainees, and staff may involve establishing a “welcome committee” for new faculty, perhaps with designating a “peer buddy,” creating social events and other opportunities for all opinions and ideas to be heard and valued. Particularly for underserved and disadvantaged patient populations, patient advocacy and community service need to be fostered through support groups and provision of resources.

Summarizing, Dr. Asare reiterated several key elements for a successful DEI program: Build a team and discuss the mission, survey the current climate allowing open communication and dialogue, plan and engage, organize, and form areas of DEI focus. Find out where you are and where you want to be with respect to DEI, she concluded.

Dr. Asare declared that she had no conflicts of interest.

Blind to Problems: How VA’s Electronic Record System Shuts Out Visually Impaired Patients

Sarah Sheffield, a nurse practitioner at a Veterans Affairs clinic in Eugene, Oregon, had a problem. Her patients — mostly in their 70s and beyond — couldn’t read computer screens. It’s not an unusual problem for older people, which is why you might think Oracle Cerner, the developers of the agency’s new digital health record system, would have anticipated it.

But they didn’t.

Federal law requires government resources to be accessible to patients with disabilities. But patients can’t easily enlarge the text. “They all learned to get strong reading glasses and magnifying glasses,” said Sheffield, who retired in early October.

The difficulties are everyday reminders of a dire reality for patients in the VA system. More than a million patients are blind or have low vision. They rely on software to access prescriptions or send messages to their doctors. But often the technology fails them. Either the screens don’t allow users to zoom in on the text, or screen-reader software that translates text to speech isn’t compatible.

“None of the systems are accessible” to these patients, said Donald Overton, executive director of the Blinded Veterans Association.

Patients often struggle even to log into websites or enter basic information needed to check in for hospital visits, Overton said: “We find our community stops trying, checks out, and disengages. They become dependent on other individuals; they give up independence.”

Now, the developing VA medical record system, already bloated by outsize costs, has been delayed until June 2023. So far, the project has threatened to exacerbate those issues.

While users in general have been affected by numerous incidents of downtime, delayed care, and missing information, barriers to access are particularly acute for blind and low-vision users — whether patients or workers within the health system. At least one Oregon-based employee has been offered aid — a helper assigned to read and click buttons — to navigate the system.

Over 1,000 Section 508 complaints are in a backlog to be assessed, or assigned to Oracle Cerner to fix, Veterans Affairs spokesperson Terrence Hayes confirmed. That section is part of federal law guaranteeing people with disabilities access to government technology.

Hayes said the problems described by these complaints don’t prevent employees and patients with disabilities from using the system. The complaints — 469 of which have been assigned to Oracle Cerner to fix, he said — mean that users’ disabilities make it more difficult, to the point of requiring mitigation.

The project is under new management with big promises. North Kansas City, Missouri-based developer Cerner, which originally landed the VA contract, was recently taken over by database technology giant Oracle, which plans to overhaul the software, company executive Mike Sicilia said during a September Senate hearing. “We intend to rewrite” the system, he said. “We have found nothing that can’t be addressed in relatively short order.”

But that will happen under continued scrutiny. Rep. Mark Takano (D-Calif.), chair of the House Veterans Affairs Committee, said his panel would continue to oversee the department’s compliance with accessibility standards. “Whether they work for VA or receive health care and benefits, the needs of veterans must be addressed by companies that want to work with the VA,” he said.

Takano, along with fellow Democrats Sens. Bob Casey of Pennsylvania and Jon Tester of Montana, sent a letter Oct. 7 to VA Secretary Denis McDonough noting the significant gaps in the agency’s systems, and urging VA to engage with all disabled veterans, not merely those who are blind.

VA was alerted early and often that Cerner’s software posed problems for blind- and low-vision users, interviews and a review of records show. As early as 2015, when the Department of Defense and VA were exploring purchasing new systems, the National Federation of the Blind submitted letters to both departments, and Cerner, expressing concerns that the product would be unusable for clinicians and patients.

Alerts also came from inside VA. “We pointed out to Cerner that their system was really dependent on vision and that it was a major problem. The icons are really, really small,” said Dr. Art Wallace, a VA anesthesiologist who participated in one of the agency’s user groups to provide input for the eventual design of the system.

The Cerner system, he told the agency and KHN, is user-unfriendly. On the clinician side, it requires multiple high-resolution monitors to display a patient’s entire record, and VA facilities don’t always enjoy that wealth of equipment. “It would be very hard for visually impaired people, or normal people wearing bifocals, to use,” he concluded.

Before the software was rolled out, the system also failed a test with an employee working with a team at Oregon’s White City VA Medical Center devoted to helping blind patients develop skills and independence, said Carolyn Schwab, president of the American Federation of Government Employees Local 1042.

In the testing, the system didn’t work with adaptive equipment, like text-to-speech software, she said. Despite receiving these complaints about the system, VA and Cerner “implemented it anyway.” Recently, when a regional AFGE president asked VA why they used the software — despite the federal mandates — he received no response, Schwab said.

Some within the company also thought there would be struggles. Two former Cerner employees said the standard medical record system was getting long in the tooth when VA signed an agreement to purchase and customize the product.

Because it was built on old code, the software was difficult to patch when problems were discovered, the employees said. What’s more, according to the employees, Cerner took a doggedly incremental approach to fixing errors. If someone complained about a malfunctioning button on a page filled with other potholes, the company would fix just that button — not the whole page, the employees said.

VA spokesperson Hayes denied the claims, saying the developer and department try to address problems holistically. Cerner did not respond to multiple requests for comment.

Accessibility errors are as present in private sector medical record systems as public. Cerner patched up a bug with the Safari web browser’s rendering of its patient portal when the Massachusetts Institute of Technology’s student clinic threatened legal action, the former employees said. (“MIT Medical does not, as a general practice, discuss individual vendor contracts or services,” said spokesperson David Tytell.)

Legal threats — with hospital systems and medical record systems routinely facing lawsuits — are the most obvious symptom of a lack of accessibility within the U.S. health care system.

Deep inaccessibility plagues the burgeoning telehealth sector. A recent survey from the American Federation for the Blind found that 57% of respondents struggled to use providers’ proprietary telehealth platforms. Some resorted to FaceTime. Many said they were unable to log in or couldn’t read information transmitted through chat sidebars.

Existing federal regulations could, in theory, be used to enforce higher standards of accessibility in health technology. The Department of Health and Human Services Office for Civil Rights issued guidance during the pandemic on making telehealth technologies easier to use for patients with disabilities. And other agencies could start leaning on hospitals, because they are recipients of government dollars or federal vendors, to make sure their offerings work for such patients.

That might not happen. These regulations could prove toothless, advocates warn. While there are several laws on the books, the advocates argue that enforcement and tougher regulations have not been forthcoming. “The concern from stakeholders is: Are you going to slow-walk this again?” said Joe Nahra, director of government relations at Powers Law, a Washington, D.C., law firm.

Building in accessibility has historically benefited all users. Voice assistance technology was originally developed to help blind- and low-vision users before winning widespread popularity with gadgets like Siri and Alexa.

Disability advocates believe vendors often push technology ahead without properly considering the impact on the people who will rely on it. “In the rush to be the first one, they put accessibility on the back burner,” said Eve Hill, a disability rights attorney with Brown, Goldstein & Levy, a civil rights law firm.

FDA approves new immunotherapy combo for liver cancer

The Food and Drug Administration has approved a new immunotherapy combination for use in the treatment of unresectable hepatocellular carcinoma (HCC), the most common type of liver cancer.

The new combination comprises a single dose of tremelimumab (Imjudo, AstraZeneca) followed by treatment with durvalumab (Imfinzi, AstraZeneca) in what is known as the STRIDE (single-tremelimumab regular-interval durvalumab) regimen.

This marks the first worldwide approval for tremelimumab, which is a CTLA-4 antibody.



The other drug in the combination, durvalumab, is an anti-PDL1 antibody and is already approved by the FDA for use in several tumor types, including lung cancer, bladder cancer, and biliary tract cancers.

The STRIDE regimen is composed of a single 300-mg dose of tremelimumab followed by durvalumab 1,500 mg given every 4 weeks.

This regimen was used in the HIMALAYA phase 3 trial, which was published in June 2022 in the New England Journal of Medicine.

Results from this trial showed that 30% of patients treated with that combination were still alive at 3 years, compared with 20% of patients who were treated with the standard regimen, sorafenib.

“In addition to this regimen demonstrating a favorable 3-year survival rate in the HIMALAYA trial, safety data showed no increase in severe liver toxicity or bleeding risk for the combination, important factors for patients with liver cancer who also have advanced liver disease,” commented the principal investigator of this trial, Ghassan Abou-Alfa, MD, MBA, attending physician at Memorial Sloan Kettering Cancer Center, New York.

“Patients with unresectable liver cancer are in need of well-tolerated treatments that can meaningfully extend overall survival,” he commented in a press release from the drug’s manufacturer, AstraZeneca.

When the results from this trial were presented earlier this year at the ASCO Gastrointestinal Cancers meeting, the discussant for that abstract, Anthony B. El-Khoueiry, MD, from the University of Southern California, Norris Comprehensive Cancer Center, Los Angeles, suggested that the STRIDE regimen offers a new first-line treatment option for patients with advanced HCC.

He also made several comments about the design of the HIMALAYA trial, which has a third treatment arm in which patients received durvalumab alone. Dr. El-Khoueiry noted that single-agent durvalumab was noninferior to sorafenib, but he added that no conclusions could be drawn about the STRIDE regimen in comparison with durvalumab as a single agent, because the trial was not powered for that.

The STRIDE regimen showed a lower risk of bleeding in comparison with combinations that include VEGF inhibitors (such as bevacizumab), he said, but he also pointed out that this trial excluded patients with main portal vein thrombosis, who are at high risk of bleeding.

Details of adverse events

In the NEJM article, the trialists report that grade 3/4 treatment-emergent adverse events occurred in 50.5% of patients with STRIDE, 37.1% with durvalumab alone, and 52.4% of patients with sorafenib.

The manufacturer noted that severe and fatal immune-mediated adverse reactions may occur, including immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, dermatologic reactions, and others.

The company also noted that among the patients with unresectable HCC in the HIMALAYA study who received the STRIDE regimen, the most common adverse reactions (occurring in ≥ 20% of patients) were rash, diarrhea, fatigue, pruritus, musculoskeletal pain, and abdominal pain.

Serious adverse reactions occurred in 41% of patients and included hemorrhage (6%), diarrhea (4%), sepsis (2.1%), pneumonia (2.1%), rash (1.5%), vomiting (1.3%), acute kidney injury (1.3%), and anemia (1.3%).

Fatal adverse reactions occurred in 8% of patients who received the combination, including death (1%), intracranial hemorrhage (0.5%), cardiac arrest (0.5%), pneumonitis (0.5%), hepatic failure (0.5%), and immune-mediated hepatitis (0.5%).

Permanent discontinuation of the treatment regimen because of an adverse reaction occurred in 14% of patients.

Results from this trial showed that 30% of patients treated with that combination were still alive at 3 years, compared with 20% of patients who were treated with the standard regimen, sorafenib.

“In addition to this regimen demonstrating a favorable 3-year survival rate in the HIMALAYA trial, safety data showed no increase in severe liver toxicity or bleeding risk for the combination, important factors for patients with liver cancer who also have advanced liver disease,” commented the principal investigator of this trial, Ghassan Abou-Alfa, MD, MBA, attending physician at Memorial Sloan Kettering Cancer Center, New York.

“Patients with unresectable liver cancer are in need of well-tolerated treatments that can meaningfully extend overall survival,” he commented in a press release from the drug’s manufacturer, AstraZeneca.

When the results from this trial were presented earlier this year at the ASCO Gastrointestinal Cancers meeting, the discussant for that abstract, Anthony B. El-Khoueiry, MD, from the University of Southern California, Norris Comprehensive Cancer Center, Los Angeles, suggested that the STRIDE regimen offers a new first-line treatment option for patients with advanced HCC.

He also made several comments about the design of the HIMALAYA trial, which has a third treatment arm in which patients received durvalumab alone. Dr. El-Khoueiry noted that single-agent durvalumab was noninferior to sorafenib, but he added that no conclusions could be drawn about the STRIDE regimen in comparison with durvalumab as a single agent, because the trial was not powered for that.

The STRIDE regimen showed a lower risk of bleeding in comparison with combinations that include VEGF inhibitors (such as bevacizumab), he said, but he also pointed out that this trial excluded patients with main portal vein thrombosis, who are at high risk of bleeding.

Details of adverse events

In the NEJM article, the trialists report that grade 3/4 treatment-emergent adverse events occurred in 50.5% of patients with STRIDE, 37.1% with durvalumab alone, and 52.4% of patients with sorafenib.

The manufacturer noted that severe and fatal immune-mediated adverse reactions may occur, including immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, dermatologic reactions, and others.

The company also noted that among the patients with unresectable HCC in the HIMALAYA study who received the STRIDE regimen, the most common adverse reactions (occurring in ≥ 20% of patients) were rash, diarrhea, fatigue, pruritus, musculoskeletal pain, and abdominal pain.

Serious adverse reactions occurred in 41% of patients and included hemorrhage (6%), diarrhea (4%), sepsis (2.1%), pneumonia (2.1%), rash (1.5%), vomiting (1.3%), acute kidney injury (1.3%), and anemia (1.3%).

Fatal adverse reactions occurred in 8% of patients who received the combination, including death (1%), intracranial hemorrhage (0.5%), cardiac arrest (0.5%), pneumonitis (0.5%), hepatic failure (0.5%), and immune-mediated hepatitis (0.5%).

Permanent discontinuation of the treatment regimen because of an adverse reaction occurred in 14% of patients.

Ready or not, hands-free devices are coming

– When Anne Chapas, MD, was asked to help conduct a clinical trial of a wearable, hands-free device for remodeling of the face and submental area, she responded with a healthy dose of skepticism.

Dr. Anne Chapas

“My first thought was, ‘this is crazy. It looks like a Storm Trooper helmet,’ ” Dr. Chapas, founder and medical director of UnionDerm, New York, said at the annual meeting of the American Society for Dermatologic Surgery. “But it’s the first FDA-cleared device that uses bipolar radiofrequency to target the lower third of the face and the submental area of the face. We wanted to see how it works.”

The device, Evoke, is the first cleared thermal facial and submental remodeling platform in the industry. Its bipolar radiofrequency (RF) component reaches 4 mm in depth and travels from central to outer electrodes. The device features real-time temperature monitoring and the ability to delivery energy at lower temps for longer periods of time compared with hands-on approaches. No cooling is required.



“It is able to treat a large surface area simultaneously to achieve maximal tissue contraction,” Dr. Chapas said. “What we’ve learned in decades of RF technology is that it’s not just about heat. It has to be the right amount of heat for the right amount of time. That’s what’s difficult when we’re doing our own individual treatments. How many pulses do we need? How is that heat dissipating? Are we getting the amount of heat we need? Is the patient in pain? We need to take that data from the individual provider and come up with an automated system. That’s what this device is trying to accomplish.”

In a prospective trial, she and her colleagues enrolled 40 patients between the ages of 36 and 75 years with visible signs of facial aging who were seeking skin tightening treatments at one of three centers in the United States. They underwent three biweekly treatments with the Evoke device to the lower face and submental area where a target temperature of 42°-43° C was maintained for 41 minutes, or about 20 minutes for each site.

For the primary safety endpoint, investigators and blinded evaluators used a 4-point Likert scale before treatment, and 1, 3, and 6 months post-treatment. Follow-up visit satisfaction metrics were the patient’s skin appearance evaluation and overall satisfaction, and the investigator improvement rating based on an analysis of volumetric data from 3D imaging software. Chin and cheek discomfort metrics were assessed at all treatments. The subject satisfaction metrics were measured on an 11-point scale where 0 is most comfortable and 10 is most uncomfortable.

In terms of safety, patients tolerated the treatments well and rated their average discomfort from 0.643 to 1.45 on the 11-point Likert scale. “The subject satisfaction rate was about 80%, which is in line with other devices, such as microfocused ultrasound,” said Dr. Chapas, who is also a clinical instructor of dermatology at the Mount Sinai Medical Center, New York.

“The physicians were a little tougher on their assessments. We felt there was about a 65%-70% success rate after the three treatment timepoints.” One possible reason for the disparity between the patient and physician assessments is that patients “may be more accepting of meager results from a hands-free treatment.”

Expect to see more hands-free devices hit the dermatology market in the coming months and years ahead, Dr. Chapas said. Before clinicians incorporate such systems into their practices, she advises them to review existing evidence for the technology, including published data and asking for demonstrations. “If it’s not efficacious, you’ve just wasted everybody’s time,” she said. “Also, is it practical for your office? Do you have the space for it? What staff training is involved? Is it truly automated?”

She added, “If you have a device that’s hands-free but someone must stay in the room with the patient for an hour, does that really help the flow of your practice? And finally, what do your patients want? Do they want to come back multiple times, or do they prefer one-and-done treatments?”

Other questions to consider, she said, include, who benefits from these treatments. Does it fill an unmet need for patients, and for clinicians? Does it help with operator fatigue? How are more consistent treatments achieved? Can the technology be applied to broad body areas?

“The hands-free revolution has been building,” Dr. Chapas commented. “The next generation of lasers and energy devices are going to be coming into our offices, so we should think carefully about how to incorporate them.”

Dr. Chapas disclosed that she is an investigator for InMode (the manufacturer of Evoke), Cutera, and Galderma, and a speaker for Allergan.

Vaginal estrogen not recommended with aromatase inhibitors

Article Type
Changed
Thu, 12/15/2022 - 17:16

Women with breast cancer who are taking adjuvant endocrine therapy to reduce the risk for recurrence often report that the side effects of dampening down estrogen, such as hot flashes and vaginal dryness, spoil their quality of life, and these side effects can lead to discontinuation of therapy.

But medical measures to address these side effects carry risks, as shown in the results of a new study from Denmark.

The use of vaginal estrogen therapy (VET) increased the risk for breast cancer recurrence by 39% in women with early estrogen receptor–positive breast cancer who were taking aromatase inhibitors (AIs).

There was no increase in the risk for recurrence in women who were using VET and taking tamoxifen or in women who were using VET and not taking any adjuvant endocrine therapy.

The finding was published in the Journal of the National Cancer Institute.

“Patients who are taking aromatase inhibitors should try alternative strategies for management of genitourinary symptoms because (VET) will likely increase their risk for breast cancer recurrence,” warn the authors of an accompanying editorial, Elizabeth J. Cathcart-Rake, MD, and Kathryn J. Ruddy, MD, oncologists at the Mayo Clinic, Rochester, Minn.

The use of oral estrogen treatment, known as menopausal hormone therapy (MHT), is also not recommended in breast cancer survivors being treated with AIs, the editorialists added.

The study did not find an increase in the risk for recurrence with MHT added onto AIs, but that finding comes from a very small subgroup of only 37 women.

“The absence of an obvious detrimental impact of MHT on breast cancer recurrence or mortality” in this study “is not particularly reassuring,” especially given higher systemic estrogen levels seen with MHT, Dr. Cathcart-Rake and Dr. Ruddy commented.
 

Differences between endocrine therapies

“Our study is, to our knowledge, the first to report a potential increased risk of recurrence in patients receiving AIs treated with VET,” say the investigators, led by Søren Cold, MD, an oncology researcher at Odense University Hospital, Denmark.

They suggest that women who are taking VET and AIs should be switched to tamoxifen after 2-3 years.

Speculating as to the apparent safety differences between the two endocrine therapies, Dr. Cold and colleagues explained that “AIs lower or nearly eliminate estrogen. As such, even a modest increase in circulating estrogens may” increase recurrence risk.

Tamoxifen, on the other hand, competes for estrogen receptor binding, so “a modest elevation of the very low serum estrogen levels” with hormone therapy “is not assumed to counteract the receptor blockade,” they said.
 

Study details

Study participants, obtained from a nationwide registry in Denmark, were diagnosed with early-stage, invasive, estrogen receptor–positive breast cancer from 1997 to 2004. Upfront treatment included surgery plus, in the majority of women, radiation.

The review identified 8,461 such women. After initial treatment for breast cancer, 2,410 went on to adjuvant endocrine therapy, including 2,007 with tamoxifen and 403 with an AI.

Across the entire study population, nearly 2,000 women took VET and 133 women took MHT, as assessed by having redeemed at least two prescriptions. The hormone therapies were used in women who were both on and those who were not on endocrine therapy.

Overall, breast cancer recurred in 1,333 women (16%) over a median follow-up of 9.8 years.

The investigators then analyzed the risk for recurrence in various subgroups.

The 39% higher risk for recurrence was found among the 822 women who used VET while taking an AI, compared with 2,520 women who received AIs alone.

Findings in the study were adjusted for numerous potential confounders, including age, tumor biology, and comorbidities.

Women were a median of 61 years of age (range, 35-91 years). Seventy-seven percent had invasive ductal carcinoma, and 43% were node-positive. Women on hormone therapy tended to be younger, have smaller tumors, and be less likely to have lymph node metastases.

The investigators excluded women who had taken hormone replacement before their breast cancer diagnosis.

The work was funded by the Danish Cancer Society. Dr. Cold reports no disclosures, but some co-authors reported relationships with Samsung, Novartis, Pfizer, and other companies. Dr. Cathcart-Rake and Dr. Ruddy report no disclosures.

Worse COVID outcomes seen with gout, particularly in women

Article Type

Wed, 10/26/2022 - 20:51

People with gout, especially women, appear to be at higher risk for poor COVID-19 outcomes, including hospitalization and death, regardless of COVID-19 vaccination status, researchers suggest.

“We found that the risks of SARS-CoV-2 infection, 30-day hospitalization, and 30-day death among individuals with gout were higher than the general population irrespective of the vaccination status,” lead study author Dongxing Xie, MD, PhD, Xiangya Hospital, Central South University, Changsha, China, and his colleagues write in their large population study. “This finding informs individuals with gout, especially women, that additional measures, even after vaccination, should be considered in order to mitigate the risk of SARS-CoV-2 infection and its severe sequelae.”

People with gout, the most common inflammatory arthritis, often have other conditions that are linked to higher risk for SARS-CoV-2 infection and poor outcomes as well, including obesity, cardiovascular disease, and chronic kidney disease, the authors write. And elevated serum urate may contribute to inflammation and possible COVID-19 complications. But unlike in the case of diseases such as lupus and rheumatoid arthritis, little is known about SARS-CoV-2 infection risk among patients with gout.

As reported in Arthritis & Rheumatology, Dr. Xie and his research team used the Health Improvement Network ([THIN], now called IQVIA Medical Research Database) repository of medical conditions, demographics, and other details of around 17 million people in the United Kingdom to estimate the risk for SARS-CoV-2 infection, hospitalization, and death in people with gout. They compared those outcomes with outcomes of people without gout and compared outcomes of vaccinated vs. nonvaccinated participants.

From December 2020 through October 2021, the researchers investigated the risk for SARS-CoV-2 breakthrough infection in vaccinated people between age 18 and 90 years who had gout and were hospitalized within 30 days after the infection diagnosis or who died within 30 days after the diagnosis. They compared these outcomes with the outcomes of people in the general population without gout after COVID-19 vaccination. They also compared the risk for SARS-CoV-2 infection and its severe outcomes between individuals with gout and the general population among unvaccinated people.

They weighted these comparisons on the basis of age, sex, body mass index, socioeconomic deprivation index score, region, and number of previous COVID-19 tests in one model. A more fully adjusted model also weighted the comparisons for lifestyle factors, comorbidities, medications, and healthcare utilization.

The vaccinated cohort consisted of 54,576 people with gout and 1,336,377 without gout from the general population. The unvaccinated cohort included 61,111 individuals with gout and 1,697,168 individuals without gout from the general population.
 

Women more likely to be hospitalized and die

The risk for breakthrough infection in the vaccinated cohort was significantly higher among people with gout than among those without gout in the general population, particularly for men, who had hazard ratios (HRs) ranging from 1.22 with a fully adjusted exposure score to 1.30 with a partially adjusted score, but this was not seen in women. The overall incidence of breakthrough infection per 1,000 person-months for these groups was 4.68 with gout vs. 3.76 without gout.

The researchers showed a similar pattern of a higher rate of hospitalizations for people with gout vs. without (0.42/1,000 person-months vs. 0.28); in this case, women had higher risks than did men, with HRs for women ranging from 1.55 with a fully adjusted exposure score to 1.91 with a partially adjusted score, compared with 1.22 and 1.43 for men, respectively.

People with gout had significantly higher mortality than did those without (0.06/1,000 person-months vs. 0.04), but the risk for death was only higher for women, with HRs calculated to be 2.23 in fully adjusted exposure scores and 3.01 in partially adjusted scores.

These same comparisons in the unvaccinated cohort all went in the same direction as did those in the vaccinated cohort but showed higher rates for infection (8.69/1,000 person-months vs. 6.89), hospitalization (2.57/1,000 person-months vs. 1.71), and death (0.65/1,000 person-months vs. 0.53). Similar sex-specific links between gout and risks for SARS-CoV-2 infection, hospitalization, and death were seen in the unvaccinated cohort.
 

 

 

Patients with gout and COVID-19 need close monitoring

Four experts who were not involved in the study encourage greater attention to the needs of patients with gout.

Dr. Pamela B. Davis


Pamela B. Davis, MD, PhD, research professor at Case Western Reserve University, Cleveland, told this news organization, “This study brings to attention yet another potentially vulnerable group for physicians to monitor closely if they are infected with SARS-CoV-2.

“It is not clear why women with gout are more vulnerable, but fewer women than men were in the cohort with gout, and the confidence intervals for the results in women were, in general, larger,” she said.

“The authors suggest that women with gout tend to be older and have more comorbidities than men with gout,” Dr. Davis added. “The excess risk diminishes when the model is fully adjusted for comorbidities, such as obesity, hypertension, or heart disease, suggesting that already-known antecedents of infection severity account for a great deal of the excess risk.”

Kevin D. Deane, MD, PhD, associate professor of medicine and chair in rheumatology research at the University of Colorado at Denver, Aurora, advises physicians to keep in mind other conditions linked with increased risk for severe COVID-19, including advanced age; heart, lung, or kidney problems; and autoimmune diseases.

Dr. Kevin D. Deane
“It will be of interest to know if treating gout leads to improved COVID-19 outcomes,” he said.

“I would be very cautious about the finding that there was not a difference in outcomes in individuals with gout based on vaccination status,” he cautioned, urging clinicians to “still strongly recommend vaccines according to guidelines.”

Sarah E. Waldman, MD, associate clinical professor of infectious diseases at UC Davis Health in Sacramento, Calif., called the study interesting but not surprising.

“The reason for increased risk for COVID-19 infection among those with gout may have to do with their underlying inflammatory state. Additional research needs to be done on this topic.

“Retrospective population-based cohort studies can be difficult to interpret due to biases,” she added. Associations identified in this type of study do not determine causation.

“As the researchers noted, those with gout tend to have additional comorbidities as well as advanced age,” she said. “They may also seek medical care more often and be tested for SARS-CoV-2 more frequently.”

Dr. Waldman advises clinicians to counsel patients with gout about their potential increased infection risk and ways they can protect themselves, including COVID-19 vaccinations.

Dr. Thanda Aung
Thanda Aung, MD, MS, a rheumatologist and assistant clinical professor of medicine at in the University of California, Los Angeles, said that women with gout appearing to be at greater risk than are men for serious COVID-19 complications is interesting, but more research to explore the link is needed.

“The strong association between gout and COVID-19 infection could involve coexisting conditions such as diabetes, hypertension, cardiovascular disease, and chronic kidney disease,” Dr. Aung added.
 

 

 

Earlier studies show links between gout and severe COVID-19 outcomes

Lead author Kanon Jatuworapruk, MD, PhD, of Thammasat University in Pathumthani, Thailand, and his colleagues investigated characteristics and outcomes of people with gout who were hospitalized for COVID-19 between March 2020 and October 2021, using data from the COVID-19 Global Rheumatology Alliance registry.

“This cohort of people with gout and COVID-19 who were hospitalized had high frequencies of ventilatory support and death,” the authors write in ACR Open Rheumatology . “This suggests that patients with gout who were hospitalized for COVID-19 may be at risk of poor outcomes, perhaps related to known risk factors for poor outcomes, such as age and presence of comorbidity.”

In their study, the average age of the 163 patients was 63 years, and 85% were men. Most lived in the Western Pacific Region and North America, and 46% had two or more comorbidities, most commonly hypertension, cardiovascular disease, diabetes, chronic kidney disease, and obesity. The researchers found that:

  • Sixty-eight percent of the cohort required supplemental oxygen or ventilatory support during hospitalization.
  • Sixteen percent of deaths were related to COVID-19, with 73% of deaths occurring in people with two or more comorbidities.

Ruth K. Topless, assistant research fellow in the department of biochemistry at the University of Otago in Dunedin, New Zealand, is the lead author on a study she and her colleagues are conducting using the UK Biobank databases of 459,837 participants in the United Kingdom, including 15,871 people with gout, through April 6, 2021, to investigate whether gout is a risk factor for diagnosis of COVID-19 and COVID-19–related death.

“Gout is a risk factor for COVID-19-related death in the UK Biobank cohort, with an increased risk in women with gout, which was driven by risk factors independent of the metabolic comorbidities of gout,” the researchers conclude in The Lancet Rheumatology.

In their study, gout was linked with COVID-19 diagnosis (odds ratio, 1.20; 95% confidence interval, 1.11-1.29) but not with risk for COVID-19–related death in the group of patients with COVID-19 (OR, 1.20; 95% CI, 0.96-1.51). In the entire cohort, gout was linked with COVID-19–related death (OR, 1.29; 95% CI, 1.06-1.56); women with gout were at increased risk for COVID-19–related death (OR, 1.98; 95% CI, 1.34-2.94), but men with gout were not (OR, 1.16; 95% CI, 0.93-1.45). The risk for COVID-19 diagnosis was significant in the nonvaccinated group (OR, 1.21; 95% CI, 1.11-1.30) but not in the vaccinated group (OR, 1.09; 95% CI, 0.65-1.85).
 

Editorial authors join in recommending further related research

In a commentary in The Lancet Rheumatology about the UK Biobank and other related research, Christoffer B. Nissen, MD, of University Hospital of Southern Denmark in Sonderborg, and his co-authors call the Topless and colleagues study “an elegantly conducted analysis of data from the UK Biobank supporting the hypothesis that gout needs attention in patients with COVID-19.”

Further studies are needed to investigate to what degree a diagnosis of gout is a risk factor for COVID-19 and whether treatment modifies the risk of a severe disease course,” they write. “However, in the interim, the results of this study could be considered when risk stratifying patients with gout in view of vaccination recommendations and early treatment interventions.”

Each of the three studies received grant funding. Several of the authors of the studies report financial involvements with pharmaceutical companies. All outside experts commented by email and report no relevant financial involvements.

People with gout, especially women, appear to be at higher risk for poor COVID-19 outcomes, including hospitalization and death, regardless of COVID-19 vaccination status, researchers suggest.

“We found that the risks of SARS-CoV-2 infection, 30-day hospitalization, and 30-day death among individuals with gout were higher than the general population irrespective of the vaccination status,” lead study author Dongxing Xie, MD, PhD, Xiangya Hospital, Central South University, Changsha, China, and his colleagues write in their large population study. “This finding informs individuals with gout, especially women, that additional measures, even after vaccination, should be considered in order to mitigate the risk of SARS-CoV-2 infection and its severe sequelae.”

People with gout, the most common inflammatory arthritis, often have other conditions that are linked to higher risk for SARS-CoV-2 infection and poor outcomes as well, including obesity, cardiovascular disease, and chronic kidney disease, the authors write. And elevated serum urate may contribute to inflammation and possible COVID-19 complications. But unlike in the case of diseases such as lupus and rheumatoid arthritis, little is known about SARS-CoV-2 infection risk among patients with gout.

As reported in Arthritis & Rheumatology, Dr. Xie and his research team used the Health Improvement Network ([THIN], now called IQVIA Medical Research Database) repository of medical conditions, demographics, and other details of around 17 million people in the United Kingdom to estimate the risk for SARS-CoV-2 infection, hospitalization, and death in people with gout. They compared those outcomes with outcomes of people without gout and compared outcomes of vaccinated vs. nonvaccinated participants.

From December 2020 through October 2021, the researchers investigated the risk for SARS-CoV-2 breakthrough infection in vaccinated people between age 18 and 90 years who had gout and were hospitalized within 30 days after the infection diagnosis or who died within 30 days after the diagnosis. They compared these outcomes with the outcomes of people in the general population without gout after COVID-19 vaccination. They also compared the risk for SARS-CoV-2 infection and its severe outcomes between individuals with gout and the general population among unvaccinated people.

They weighted these comparisons on the basis of age, sex, body mass index, socioeconomic deprivation index score, region, and number of previous COVID-19 tests in one model.

New electrodes made of sugar more effectively monitor mom’s health

Article Type

Mon, 10/24/2022 - 15:55

A new type of electrode made from sugar could help doctors and researchers more effectively monitor contractions during preterm labor, a condition that precedes almost half of preterm births and is the leading cause of U.S. neonatal deaths.

The sensors, developed by engineers at the McKelvey School of Engineering at Washington University, St. Louis, could help us understand why some patients experience preterm labor, improve medical interventions, and save lives. In the experiment, the researchers built an array of the new electrodes and successfully tested it on a pregnant person in a lab.

The goal is a home-monitoring belt that is comfortable enough for patients to wear and accurate enough to be clinically useful. Built off a framework of sugar and conductive polymers, the thin electrodes have a sponge-like quality that allows them to hold more gel than standard electrodes, measure for 3 hours instead of 1, and resist artifacts created by patient movement. When tested on a pregnant woman, the new electrodes picked up clean signals even when the patient moved, said electrical engineer and article co-author Chuan Wang, PhD.

There is current technology that exists to monitor and map contractions during early labor, but the tests require hundreds of wire electrodes. Patients must sit still for half an hour while the electrodes are applied, then remain immobile for the test itself, which has a high sensitivity to movement.

“It’s very uncomfortable. In the clinical setting, the recording typically lasts for 15 minutes to half an hour. During that time, doctors want the patient to be still,” said Dr. Wang. “If the patient has to move, it’s going to introduce some artifacts, which is going to ruin the imaging process.”

Dr. Wang and colleagues wanted to develop an inexpensive new electrode that would be more comfortable for patients to wear for longer periods of time, yet sensitive enough to detect electrical signals in the body during preterm labor.

To do this, they used sugar structures to create a pliable electrode with a spongy structure. The new electrodes have micropores that hold conductive gel, increasing the amount of electrified surface area touching the skin.

“With the porous structure, we are effectively increasing the area by many, many times,” Dr. Wang said. “Because all those voids also contact the skin, increasing the contact area can boost the strength of the signal.”

With conventional electrodes, the gel dries quickly on the flat surface, causing signal quality to plummet. But the new electrodes can be used for “many hours” before drying out, according to Dr. Wang.

Additionally, the soft material of the new electrode acts “like a buffer” that absorbs motion and prevents the electrode from sliding around, according to Dr. Wang. That means patients can move while wearing the spongy electrodes without disturbing the recording of electrical signals in the body.
 

From sugar cube to spongy electrode

To create the new electrode, the researchers began by molding sugar into an electrode-shaped template. The template was then dipped into a liquid polymer, which oozed in between the grains of sugar. Next, the template underwent oven curing, emerging as a solid yet spongy structure. Hot water was then applied to dissolve the sugar.

 

 

The sugar structure is useful here because of the negative space around the grains, which is filled by the polymer – and then because of the negative space left when the sugar dissolves.

“When the sugar grains are removed, that’s where the pores are located,” Dr. Wang explained.

The sponge surface was then converted from hydrophobic to hydrophilic, thanks to an oxygen plasma treatment. Next, the sponge was blanketed in a layer of conductive polymer – a liquid that Dr. Wang likens to black ink – transforming it into an electrode. (Without the oxygen plasma step, the sponge wouldn’t have absorbed the conductive material.) After another oven-curing session, the device was affixed with wires and ready to be used.

The researchers are continuing to refine the concept and hope to develop a wireless wearable device with many spongy electrodes that record signals simultaneously – and that patients can use at home.

In addition to monitoring maternal and fetal health during labor, the researchers say the belt-like device could be used for other types of imaging and diagnosis.

“Depending on the scenario, different signals can be recorded,” Dr. Wang said. “It could be an EMG for a pregnant woman, or an ECG for an athlete or a patient with chronic cardiovascular disease that needs monitoring.”

A new type of electrode made from sugar could help doctors and researchers more effectively monitor contractions during preterm labor, a condition that precedes almost half of preterm births and is the leading cause of U.S. neonatal deaths.

The sensors, developed by engineers at the McKelvey School of Engineering at Washington University, St. Louis, could help us understand why some patients experience preterm labor, improve medical interventions, and save lives. In the experiment, the researchers built an array of the new electrodes and successfully tested it on a pregnant person in a lab.

The goal is a home-monitoring belt that is comfortable enough for patients to wear and accurate enough to be clinically useful. Built off a framework of sugar and conductive polymers, the thin electrodes have a sponge-like quality that allows them to hold more gel than standard electrodes, measure for 3 hours instead of 1, and resist artifacts created by patient movement. When tested on a pregnant woman, the new electrodes picked up clean signals even when the patient moved, said electrical engineer and article co-author Chuan Wang, PhD.
