FDA okays terlipressin (Terlivaz) injection for hepatorenal syndrome
The Food and Drug Administration has approved terlipressin (Terlivaz), the first and only drug approved for patients with hepatorenal syndrome (HRS).
HRS is characterized by progressive deterioration in kidney function in people with advanced liver disease.
Terlipressin is an injectable synthetic vasopressin analogue indicated for patients with HRS who are experiencing rapid deterioration of kidney function (type 1 HRS). The condition affects an estimated 35,000 Americans annually.
The safety and efficacy of terlipressin for type 1 HRS was assessed in the phase 3 CONFIRM trial, which involved 300 patients in the United States and Canada.
Patients received an injection of terlipressin (0.85 mg) or placebo every 6 hours for a maximum of 14 days. The dose was adjusted on the basis of changes in kidney function.
Twenty-nine percent of patients in the terlipressin group experienced improvement in kidney function, vs. 16% in the placebo group.
The CONFIRM trial met its primary endpoint of verified HRS reversal, defined as renal function improvement, avoidance of dialysis, and short-term survival (P = .012).
To achieve this endpoint, patients had to have two consecutive serum creatinine (SCr) values of ≤ 1.5 mg/dL at least 2 hours apart by day 14 or be discharged from the hospital.
The most commonly observed adverse reactions that occurred in at least 4% of patients treated with terlipressin were abdominal pain (19.5%), nausea (16%), respiratory failure (15.5%), diarrhea (13%), and dyspnea (12.5%).
Results of the CONFIRM trial were published in The New England Journal of Medicine.
“Diagnosing and treating HRS can be challenging, and every minute counts when managing patients who have it,” said Steven Romano, MD, executive vice president and chief scientific officer at Mallinckrodt, which makes the drug.
“Terlivaz gives physicians the first FDA-approved option for treating HRS patients with rapid reduction in kidney function that may help them improve kidney function and lessen the associated need for renal replacement therapy, such as dialysis,” Dr. Romano said.
The company plans to launch the product in the coming weeks.
The application for terlipressin for HRS was granted priority review and fast-track status, as well as orphan drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.

Cell-killing cancer therapy treats lupus successfully
In a first-of-its-kind clinical trial, researchers in Germany used a cancer-killing cell therapy to successfully treat lupus in a small number of patients.
Their study, published online in Nature Medicine, included five patients with systemic lupus erythematosus (SLE). All of the patients were treated with chimeric antigen receptor (CAR) T-cell therapy, a treatment regularly used to kill cancer cells. Researchers harvested the patients’ immune cells and engineered them to destroy dysfunctional cells when infused back into the body.
The five patients – all of whom had an aggressive form of the autoimmune disease – underwent a single infusion of the experimental treatment. All five patients were able to stop their standard treatments for as long as 17 months following the therapy, the study found. The patients also stopped experiencing severe symptoms such as lung inflammation, fibrosis of the heart valves, arthritis, and fatigue. The patients have not relapsed.
“Our data reveal unexpected insights for a role of CAR T cells in nonmalignant diseases that could provide new opportunities for the treatment of autoimmune disease,” the study authors wrote.
Lupus is a chronic inflammatory disease in which the immune system attacks the body’s own cells. Both antibody-producing B and T cells in individuals with lupus become overactive, which can lead to a flare of symptoms that range from mild pain and fatigue to life-threatening inflammation and tissue damage. They are often treated with medications that deplete their B cells or change the way they function to help wipe out infected cells.
The approach used by the study researchers is similar to monoclonal antibody therapies that destroy dysfunctional B cells, such as rituximab (Rituxan and biosimilars) and obinutuzumab (Gazyva), according to Michael Belmont, MD, codirector of New York University’s Lupus Center and medical director of Bellevue Hospital Lupus Clinic, also in New York.
“Previously, this has been accomplished with monoclonal antibodies that target surface markers on B cells and results in their removal,” said Dr. Belmont, who was not connected to the study. “The report describes a novel approach that harnesses a patient’s own T cells, another type of white blood cell, to eliminate that patient’s own B cells.”
Preclinical studies involving mice previously showed that CAR T-cell therapy could help to reset the immune system. However, this latest study also found that patients did not need to continue any of their previous therapies, even after they regained their B cells about 4 months after the therapy.
“A deep depletion of CD19+ B cells and plasmablasts in the tissues could trigger an immune reset in SLE that could allow the cessation of immunosuppressive treatment,” said Mehrnaz Hojjati, MD, a rheumatologist and director of rheumatology operations at Loma Linda (Calif.) University Health. Dr. Hojjati was not affiliated with the study.
While the single-treatment therapy is promising, transfused T cells do carry risks. Some of the patients in the study experienced fever and muscle pain following the procedure, the authors noted. Dr. Belmont said more serious risks for this kind of therapy may include organ injury.
“This treatment can [also] increase incidence, for example, of pneumonia or shingles,” he said.
The study authors initially documented their work in a correspondence published in August 2021 in the New England Journal of Medicine. At that time, they reported that a 20-year-old woman with a severe refractory SLE went into remission following the treatment.
The five patients in the current study – four women and one man – were aged 18-24 years. All of the patients had previously been treated with several immunosuppressive medications, the study authors noted.
“This is an exciting approach, but many more patients need to be treated to really understand the efficacy and safety,” Dr. Belmont said.
Experts, including Dr. Belmont, also said the procedure is also costly and requires access to labs that can engineer a patient’s own T cells after they’ve been donated.
“The entire process must maintain sterility to avoid contamination, which would be harmful when reinfused into the patient,” he said.
According to Arthur Kavanaugh, MD, professor of medicine at UC San Diego Health, this form of therapy may be an option for severe refractory patients who have not responded well to other more established therapies.
“[It’s] exciting data, but very intense and so not likely to be something for an average patient in the near future,” said Dr. Kavanaugh, who was not affiliated with the study.
The study authors say they intend to create a larger trial to further explore which type of patient may benefit the most from this treatment, and for how long.
The study was supported by the German Research Foundation, the German Federal Ministry of Education and Research, the European Union, and the Innovative Medicines Initiative–funded project, Rheuma Tolerance for Cure. The study received no commercial funding, and the authors said they had no competing interests related to the study. None of the experts interviewed reported relevant financial relationships.

FDA OKs sodium thiosulfate injection to reduce ototoxicity risk in children with cancer
This approval makes sodium thiosulfate the first and only treatment FDA-approved in this area.
“Historically, there have been no approved treatments for preventing cisplatin-induced hearing loss,” said David R. Freyer, DO, of Children’s Hospital Los Angeles and primary investigator of one of the two trials, COG ACCL0431. The FDA’s approval “addresses an enormous unmet need for many children and young adults.”
The approval was based on safety and efficacy data from two multicenter open-label, randomized controlled phase 3 trials – SIOPEL 6 and COG ACCL0431 – comparing sodium thiosulfate plus a cisplatin-based regimen to a cisplatin-based regimen alone in pediatric patients. SIOPEL 6 included patients with standard risk hepatoblastoma, and COG ACCL0431 included pediatric patients with solid tumors.
In both studies, the incidence of hearing loss was significantly lower in the sodium thiosulfate group, compared with the cisplatin-only group. In SIOPEL 6, hearing loss of grade 1 or higher occurred in 33% of children (18 of 55) in the cisplatin–sodium thiosulfate group and 63% (29 of 46) in the cisplatin-only group, indicating a 48% lower incidence of hearing loss for those receiving sodium thiosulfate. In COG ACCL0431, hearing loss was identified in 28.6% of patients (14 of 49) receiving sodium thiosulfate, compared with 56.4% (31 of 55) in the control group, indicating a 69% lower risk for hearing loss in the sodium thiosulfate group.
The FDA reported the same overall trend but highlighted slightly different figures. In SIOPEL 6, hearing loss incidence occurred in 39% of patients (24 of 61) in the sodium thiosulfate arm versus 68% (36 of 53) in the control group; in COG ACCL0431, hearing loss incidence occurred among 44% of patients (17 of 39) in the sodium thiosulfate group versus 58% (22 of 38) in the control group.
The recommended dose is based on surface area according to body weight. Sodium thiosulfate is administered as an intravenous infusion over 15 minutes following cisplatin infusions that are 1 to 6 hours in duration.
Serious adverse reactions occurred in 40% of patients who received cisplatin–sodium thiosulfate in SIOPEL 6 and 36% of these patients in COG ACCL0431. The most common adverse reactions in the trials included vomiting, infection, nausea, decreased hemoglobin, hypernatremia, and hypokalemia.

Genetic tests create treatment opportunities and confusion for breast cancer patients
The past decade has witnessed a rapid expansion of genetic tests, including new instruments to inform patients who have been diagnosed with breast cancer about the risk of recurrence and to guide their treatment.
Patients are sometimes left paying out-of-pocket for exams that are not yet the standard of care, and even the most up-to-date oncologists may be uncertain how to incorporate the flood of new information into what used to be standard treatment protocols.
A quarter-century ago, Myriad Genetics introduced the first breast cancer genetic test for BRCA mutations, two genes associated with a substantially elevated risk of getting breast cancer, opening the door to a new era in genetic testing. BRCA1 and BRCA2 mutations account for as many as half of all hereditary breast cancers, and people with a problematic mutation on one of those genes have a 45%-72% chance of developing breast cancer during their lifetimes. They may also be at higher risk for ovarian and other cancers than people without harmful BRCA mutations.
But the clinical significance is murkier for many other genetic tests.
Testing for BRCA1 and BRCA2 genes used to cost thousands of dollars. Now, for a fraction of that, doctors can order multigene test panels from commercial labs that look for mutations in dozens of genes. Some direct-to-consumer companies offer screening panels for a few hundred dollars, though their reliability varies.
When Jen Carbary was diagnosed with breast cancer in 2017 at age 44, genetic testing identified a mutation in a gene called PALB2 that significantly increases the risk of developing breast cancer. Guidelines suggest that breast cancer patients with a PALB2 mutation, much like those with BRCA1 and BRCA2 mutations, consider having a mastectomy to reduce the chance of a breast cancer recurrence.
“I wish genetic testing was the standard of care,” said Ms. Carbary, who owed nothing for the test because her insurer covered the cost.
Ms. Carbary, who lives in Sterling Heights, Mich., said the test results affirmed the decision she had already made to have a double mastectomy and provided important information for family members, including her 21-year-old daughter and 18-year-old son, who will likely be tested in their mid-20s or early 30s.
But some breast cancer experts are concerned that widespread testing may also identify genetic mutations whose impact is unclear, creating anxiety and leading to further testing and to treatment of questionable value that could raise costs for the health care system.
It can also confuse patients.
“It happens a lot, that patients find their way to us after getting confusing results elsewhere,” said Mark Robson, MD, chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York. Robson said the cancer center has a clinical genetics service, staffed by doctors and genetic counselors, that helps people make decisions about how to manage genetic testing results.
For people diagnosed with breast cancer, many professional groups, including the influential National Comprehensive Cancer Network, recommend limiting testing to certain people, including those with high-risk factors, such as a family history of breast cancer; those who are 45 or younger when they’re diagnosed; and those with Ashkenazi Jewish ancestry.
But in 2019, the American Society of Breast Surgeons recommended a different approach: Offer genetic testing to all patients who are diagnosed with or have a personal history of breast cancer. The recommendation was controversial.
“The NCCN guidelines [cover] most of the women who needed testing, but we wanted to get them all,” said Eric Manahan, MD, a general surgeon in Dalton, Georgia, and a member of the surgeons group’s board of directors.
Mutations on other genes that are associated with breast cancer are much less common than BRCA1 and BRCA2 mutations and generally don’t increase the risk of developing breast cancer as much. The cancer-causing impact of these genes may be less clear than that of the BRCA genes, which have been tested for since the mid-1990s.
And the appropriate response to the less common mutations – whether to consider a risk-reducing mastectomy or stepped-up screening – is often unclear.
“Things get sloppier and sloppier when you look at other genes,” said Steven Katz, MD, MPH, a professor of medicine and health management and policy at the University of Michigan. “The risks tend to be lower for different cancers, and less certain and more variable. You might walk away wondering: ‘Why’d I have to know that?’ ”
After people are diagnosed with breast cancer, genetic testing can help inform their decisions about the types of surgery to pursue – for example, a high risk of recurrence or a new breast cancer might persuade some to opt for more extensive surgery, such as a double mastectomy. Testing can also provide important information to family members about their potential cancer risk.
(This type of “germline” genetic testing, as it’s called, looks at mutations in the genes that people inherit from their parents. It is different from genomic tumor tests that look at specific genes or proteins in the cancer cells and can help doctors understand the rate at which the cancer cells are dividing, for example, and the likelihood of a cancer recurrence.)
Increasingly, germline genetic testing can also help guide other treatment decisions. Some patients with metastatic breast cancer who have BRCA1 or BRCA2 mutations may be good candidates for poly (ADP-ribose) polymerase inhibitors, cancer drugs that target tumors with mutations in those genes.
But genetic testing that uncovers inherited mutations in many other genes yields less clearly actionable information, even though positive results may alarm people.
At Memorial Sloan Kettering, cancer specialists focus on “therapeutic actionability,” said Dr. Robson. Will testing help someone decide whether she should get a double mastectomy or provide other important guidance? “A policy of testing everyone will identify very few additional BRCA breast mutations but will cost a lot.”
As a result, doctors are debating how best to deploy and incorporate new genetic knowledge. Insurers are trying to figure out which to pay for.
There is both underuse of tests that science says are relevant and overuse of tests that experts say provide information that can’t be interpreted with any scientific certainty.
The result may be confusion for patients newly diagnosed with breast cancer as they confront the expense of genetic tests and sometimes little guidance on the proper treatment.
Some doctors say the first step is to make sure that the small group of people who would clearly benefit are getting the genetic tests whose meaning is clearly understood. Only 15% of breast cancer patients who met select NCCN testing guidelines for inherited cancer received genetic testing, according to a 2017 study that examined data from a national household health survey between 2005 and 2015.
“I would argue that our focus needs to be on the people who are at high risk for breast cancer that aren’t even identified yet,” said Tuya Pal, MD, associate director for cancer health disparities at Vanderbilt-Ingram Cancer Center and vice chair of the NCCN guidelines panel for genetic/familial high-risk assessment of breast, ovarian, and pancreatic cancers.
Patients may fall through the cracks because no one tells them they should be tested. In one analysis, 56% of high-risk breast cancer patients who didn’t get genetic testing said their doctors didn’t recommend it.
Even if doctors recommend genetic testing, they may lack the expertise to determine which tests people need and how to interpret the results. That’s the role of genetic counselors, but their ranks are stretched thin.
The consequences can be serious. In a study of 666 breast cancer patients who received genetic testing, half of those at average risk for inherited cancer got double mastectomies based on test results that found “variants of uncertain significance,” which aren’t clinically actionable. As many as half of surgeons reported managing such patients the same way as those with cancer-causing mutations.
“The bulk of our research would say that there is still room for improvement in terms of clinicians getting the understanding they need,” said Allison Kurian, MD, director of the women’s clinical cancer genetics program at Stanford (Calif.) University and a coauthor of the study.

The past decade has witnessed a rapid expansion of genetic tests, including new instruments to inform patients who have been diagnosed with breast cancer about the risk of recurrence and to guide their treatment.
Patients are sometimes left paying out-of-pocket for exams that are not yet the standard of care, and even the most up-to-date oncologists may be uncertain how to incorporate the flood of new information into what used to be standard treatment protocols.
A quarter-century ago, Myriad Genetics introduced the first breast cancer genetic test for BRCA mutations, two genes associated with a substantially elevated risk of getting breast cancer, opening the door to a new era in genetic testing. BRCA1 and BRCA2 mutations account for as many as half of all hereditary breast cancers, and people with a problematic mutation on one of those genes have a 45%-72% chance of developing breast cancer during their lifetimes. They may also be at higher risk for ovarian and other cancers than people without harmful BRCA mutations.
But the clinical significance is murkier for many other genetic tests.
Testing for BRCA1 and BRCA2 genes used to cost thousands of dollars. Now, for a fraction of that, doctors can order multigene test panels from commercial labs that look for mutations in dozens of genes. Some direct-to-consumer companies offer screening panels for a few hundred dollars, though their reliability varies.
When Jen Carbary was diagnosed with breast cancer in 2017 at age 44, genetic testing identified a mutation in a gene called PALB2 that significantly increases the risk of developing breast cancer. Guidelines suggest that breast cancer patients with a PALB2 mutation, much like those with BRCA1 and BRCA2 mutations, consider having a mastectomy to reduce the chance of a breast cancer recurrence.
“I wish genetic testing was the standard of care,” said Ms. Carbary, who owed nothing for the test because her insurer covered the cost.
Ms. Carbary, who lives in Sterling Heights, Mich., said the test results affirmed the decision she had already made to have a double mastectomy and provided important information for family members, including her 21-year-old daughter and 18-year-old son, who will likely be tested in their mid-20s or early 30s.
But some breast cancer experts are concerned that widespread testing may also identify genetic mutations whose impact is unclear, creating anxiety and leading to further testing and to treatment of questionable value that could raise costs for the health care system.
It can also confuse patients.
“It happens a lot, that patients find their way to us after getting confusing results elsewhere,” said Mark Robson, MD, chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York. Robson said the cancer center has a clinical genetics service, staffed by doctors and genetic counselors, that helps people make decisions about how to manage genetic testing results.
For people diagnosed with breast cancer, many professional groups, including the influential National Comprehensive Cancer Network, recommend limiting testing to certain people, including those with high-risk factors, such as a family history of breast cancer; those who are 45 or younger when they’re diagnosed; and those with Ashkenazi Jewish ancestry.
But in 2019, the American Society of Breast Surgeons recommended a different approach: Offer genetic testing to all patients who are diagnosed with or have a personal history of breast cancer. The recommendation was controversial.
“The NCCN guidelines [cover] most of the women who needed testing, but we wanted to get them all,” said Eric Manahan, MD, a general surgeon in Dalton, Georgia, and a member of the surgeons group’s board of directors.
Mutations on other genes that are associated with breast cancer are much less common than BRCA1 and BRCA2 mutations and generally don’t increase the risk of developing breast cancer as much. The cancer-causing impact of these genes may be less clear than that of the BRCA genes, which have been tested for since the mid-1990s.
And the appropriate response to the less common mutations – whether to consider a risk-reducing mastectomy or stepped-up screening – is often unclear.
“Things get sloppier and sloppier when you look at other genes,” said Steven Katz, MD, MPH, a professor of medicine and health management and policy at the University of Michigan. “The risks tend to be lower for different cancers, and less certain and more variable. You might walk away wondering: ‘Why’d I have to know that?’ ”
After people are diagnosed with breast cancer, genetic testing can help inform their decisions about the types of surgery to pursue – for example, a high risk of recurrence or a new breast cancer might persuade some to opt for more extensive surgery, such as a double mastectomy. Testing can also provide important information to family members about their potential cancer risk.
(This type of “germline” genetic testing, as it’s called, looks at mutations in the genes that people inherit from their parents. It is different from genomic tumor tests that look at specific genes or proteins in the cancer cells and can help doctors understand the rate at which the cancer cells are dividing, for example, and the likelihood of a cancer recurrence.)
Increasingly, germline genetic testing can also help guide other treatment decisions. Some patients with metastatic breast cancer who have BRCA1 or BRCA2 mutations may be good candidates for poly (ADP-ribose) polymerase inhibitors, cancer drugs that target tumors with mutations in those genes.
But genetic testing that uncovers inherited mutations in many other genes yields less clearly actionable information, even though positive results may alarm people.

Could cold exposure, especially shivering, combat type 2 diabetes?
STOCKHOLM – Shivering upon repeated short exposures to cold improves glucose tolerance, decreases fasting blood glucose and lipid levels, and markedly reduces blood pressure, show new study results in adults with obesity and overweight.
Presenting the preliminary findings at the annual meeting of the European Association for the Study of Diabetes, Adam Sellers, a PhD student from Maastricht (the Netherlands) University, said: “The results are highly promising and may eventually suggest an alternative treatment or preventative measure for type 2 diabetes.”
Dr. Sellers found that 10 daily 1-hour sessions of shivering at 10° C led to 85% of participants showing a drop in fasting glucose, and a 32% drop in lipid levels, as well as a blood pressure drop of around 8% overall.
Although cold exposure is known to increase brown fat, Dr. Sellers doesn’t believe this explains his findings. “This research, in addition to two other prior studies, suggest that shivering and skeletal muscle may play a more important role than brown fat,” he said.
“Muscle can contract mechanically – [the concept of the] shivers – thereby generating heat, and there is considerably more muscle than brown fat in a human, so shivering can burn more calories and produce more heat,” he explained.
He added that, in the future, “in a similar way to saunas and steam rooms, there might be cold rooms where people go and sit in the cold room and shiver, or possibly patients attend hospital and shivering is induced.”
Audience member Anna Krook, PhD, professor of integrative physiology at the Karolinska Institute, Stockholm, commented on the work, saying the results are “potent” and demonstrate the metabolic effect of shivering. “One thing that struck me was, given the time the subject had to spend – 1 hour shivering over 10 days, I wonder if 1 hour of exercise would show similarly potent effects, and perhaps for those people who cannot perform exercise for whatever reason this might be a good alternative.”
She pointed out that, in terms of translation into practice, it “really depends on how tolerable this is. It also shows how important our muscle is in regulating metabolism. The study showed that you had to be shivering, and it wasn’t just enough to be cold, which has implications for the role of brown fat, especially when we consider the small amount of brown fat we have compared to muscle, which can be half of body weight.”
And Denis P. Blondin, PhD, said: “The reality is that we know it can be difficult and even painful for individuals with obesity to perform exercise, and therefore, cold exposure offers a passive way of improving our metabolic profile and cardiovascular health.”
“Some will argue that it is unrealistic to propose cold exposure as a therapy, but people overlook the fact that cold exposure [mostly through cold-water immersion] has increased in popularity over the past 5 years and has also been a cultural staple for many Nordic countries, albeit often performed with heat exposure as well [see the use of saunas and cold-water swimming in Finland and other Nordic countries],” added Dr. Blondin, of the faculty of medicine and health sciences, University of Sherbrooke (Que.)
“While it can certainly be uncomfortable at first (like starting an exercise program), we adapt very quickly,” he added.
1 hour in a cold-water suit to induce shivering
In the current study, Dr. Sellers exposed adults (aged 40-75 years; 11 men and 4 postmenopausal women) with overweight/obesity (body mass index, 27-35 kg/m2) to 10 consecutive cold exposures of at least 1 hour of shivering per cold exposure.
“The shivering in this new research was more intense [than in prior studies] and was induced with a different cold exposure method – a 10° C water-perfused suit [compared with a prior study of 14-15° C, 6 hours/day]. This facilitated a shorter cold exposure duration, deemed feasible for the participants,” explained Dr. Sellers.
“At baseline, participants had glucose and A1c levels at the upper end of the normal criteria [5.5 mmol/l and 5.4%, respectively],” he said, referring to measurements that were suggestive of possible progression to type 2 diabetes.
He explained how the cold exposure was applied. “We induced the cold with a water-perfused suit worn by the participant, through which water flows at 10° C, and this cools the participant. Eventually, the participant starts to shiver, and does so for at least 1 hour every morning for 10 days.”
Participants’ shivering-induced heat production was measured via surface electromyography and visual observation to confirm the presence of shivering. Both before and after the 10-day course of shivering, physiological measurements were taken in the morning while participants were at rest in an overnight fasted state, and under thermoneutral conditions. Blood pressure and fasting blood glucose were measured.
A 2-hour oral glucose tolerance test (OGTT) was conducted twice for each participant: on the morning before the 10-day course of shivering and again on the morning after the final 10th day of shivering.
The primary endpoint was change from before to after the 10-day shivering intervention, as represented by the total area under the curve of glucose levels over time during the OGTT.
“This provides a measure of the glucose concentrations in the blood before and after the 10 shivering sessions over the 10 days.”
Fasting glucose and blood lipids fall, glucose tolerance improves
After 10 shivering sessions, mean fasting plasma glucose decreased significantly in 13 out of the 15 participants, compared with before the first session (from 5.84 mmol/L to 5.67 mmol/L; P = .013).
Glucose tolerance during the OGTT improved by 6% (P = .041). “We can see that this was not due to a change in their insulin concentrations in the blood,” remarked Dr. Sellers, referring to the finding that plasma insulin concentrations at baseline and during the OGTT did not change.
Fasting plasma triglyceride and free-fatty acid concentrations also decreased significantly by 32% (P = .001) and 11% (P = .036), respectively.
“This is important because free-fatty acids are involved in the role of insulin resistance,” said Dr. Sellers. “In addition, the large reduction in serum triglycerides could have implications for atherosclerosis, which may also be beneficial.”
Dr. Sellers also found that systolic blood pressure decreased by 10 mm Hg or 7.4% (P < .001), while diastolic blood pressure decreased by 7 mm Hg or 8.1% (P < .001) on average. This lowering was seen in all participants.
“Again, quite strikingly, all participants showed” a reduction in blood pressure, said Dr. Sellers, which he noted relates to a decrease in resting heart rate (P = .062).
Brown fat or skeletal muscle contraction?
Dr. Sellers pointed out that, despite nonshivering thermogenesis being involved in mild cold acclimation, the data so far suggest that some level of mild muscle activity or shivering appears crucial in provoking the beneficial metabolic effects of cold acclimation.
“Brown fat is a metabolic heating system inside our bodies, burning calories”, explained Dr. Sellers. “This generates heat and prevents calories from being deposited as normal white fat. Brown fat is activated during cold and when we eat, but its activity is less in older adults and in individuals with obesity and diabetes.”
“Going forward, we might investigate the effects of shorter duration – so more intense shivering – to try and elucidate more precisely the optimum duration and intensity of shivering needed,” said Dr. Sellers.
“Our findings are promising and may have important health implications. In future studies, we plan to assess the effect of shivering in adults with type 2 diabetes,” he concluded.
Dr. Seller and Dr. Krook have reported no relevant financial relationships.

He added that, in the future, “in a similar way to saunas and steam rooms, there might be cold rooms where people go and sit in the cold room and shiver, or possibly patients attend hospital and shivering is induced.”
Audience member Anna Krook, PhD, professor of integrative physiology at the Karolinska Institute, Stockholm, commented on the work, saying the results are “potent” and demonstrate the metabolic effect of shivering. “One thing that struck me was, given the time the subject had to spend – 1 hour shivering over 10 days, I wonder if 1 hour of exercise would show similarly potent effects, and perhaps for those people who cannot perform exercise for whatever reason this might be a good alternative.”
She pointed out that, in terms of translation into practice, it “really depends on how tolerable this is. It also shows how important our muscle is in regulating metabolism. The study showed that you had to be shivering, and it wasn’t just enough to be cold, which has implications for the role of brown fat, especially when we consider the small amount of brown fat we have compared to muscle, which can be half of body weight.”
And Denis P. Blondin, PhD, said: “The reality is that we know it can be difficult and even painful for individuals with obesity to perform exercise, and therefore, cold exposure offers a passive way of improving our metabolic profile and cardiovascular health.”
“Some will argue that it is unrealistic to propose cold exposure as a therapy, but people overlook the fact that cold exposure [mostly through cold-water immersion] has increased in popularity over the past 5 years and has also been a cultural staple for many Nordic countries, albeit often performed with heat exposure as well [see the use of saunas and cold-water swimming in Finland and other Nordic countries],” added Dr. Blondin, of the faculty of medicine and health sciences, University of Sherbrooke (Que.)
“While it can certainly be uncomfortable at first (like starting an exercise program), we adapt very quickly,” he added.
1 hour in a cold-water suit to induce shivering
In the current study, Dr. Sellers exposed adults (aged 40-75 years; 11 men and 4 postmenopausal women) with overweight/obesity (body mass index, 27-35 kg/m2) to 10 consecutive cold exposures of at least 1 hour of shivering per cold exposure.
“The shivering in this new research was more intense [than in prior studies] and was induced with a different cold exposure method – a 10° C water-perfused suit [compared with a prior study of 14-15° C, 6 hours/day]. This facilitated a shorter cold exposure duration, deemed feasible for the participants,” explained Dr. Sellers.
“At baseline, participants had glucose and A1c levels at the upper end of the normal criteria [5.5 mmol/l and 5.4%, respectively],” he said, referring to measurements that were suggestive of possible progression to type 2 diabetes.
He explained how the cold exposure was applied. “We induced the cold with a water-perfused suit worn by the participant, through which water flows at 10° C, and this cools the participant. Eventually, the participant starts to shiver, and does so for at least 1 hour every morning for 10 days.”
Participants’ shivering-induced heat production was measured via surface electromyography and visual observation to confirm the presence of shivering. Both before and after the 10-day course of shivering, physiological measurements were taken in the morning while participants were at rest in an overnight fasted state, and under thermoneutral conditions. Blood pressure and fasting blood glucose were measured.
A 2-hour oral glucose tolerance test (OGTT) was conducted twice for each participant: on the morning before the 10-day course of shivering and again on the morning after the final 10th day of shivering.
The primary endpoint was change from before to after the 10-day shivering intervention, as represented by the total area under the curve of glucose levels over time during the OGTT.
“This provides a measure of the glucose concentrations in the blood before and after the 10 shivering sessions over the 10 days.”
Fasting glucose and blood lipids fall, glucose tolerance improves
After 10 shivering sessions, mean fasting plasma glucose decreased significantly in 13 out of the 15 participants, compared with before the first session (from 5.84 mmol/L to 5.67 mmol/L; P = .013).
Glucose tolerance during the OGTT improved by 6% (P = .041). “We can see that this was not due to a change in their insulin concentrations in the blood,” remarked Dr. Sellers, referring to the finding that plasma insulin concentrations at baseline and during the OGTT did not change.
Fasting plasma triglyceride and free-fatty acid concentrations also decreased significantly by 32% (P = .001) and 11% (P = .036), respectively.
“This is important because free-fatty acids are involved in the role of insulin resistance,” said Dr. Sellers. “In addition, the large reduction in serum triglycerides could have implications for atherosclerosis, which may also be beneficial.”
Dr. Sellers also found that systolic blood pressure decreased by 10 mm Hg or 7.4% (P < .001), while diastolic blood pressure decreased by 7 mm Hg or 8.1% (P < .001) on average. This lowering was seen in all participants.
“Again, quite strikingly, all participants showed” a reduction in blood pressure, said Dr. Sellers, which he noted relates to a decrease in resting heart rate (P = .062).
Brown fat or skeletal muscle contraction?
Dr. Sellers pointed out that, despite nonshivering thermogenesis being involved in mild cold acclimation, the data so far suggest that some level of mild muscle activity or shivering appears crucial in provoking the beneficial metabolic effects of cold acclimation.
“Brown fat is a metabolic heating system inside our bodies, burning calories”, explained Dr. Sellers. “This generates heat and prevents calories from being deposited as normal white fat. Brown fat is activated during cold and when we eat, but its activity is less in older adults and in individuals with obesity and diabetes.”
“Going forward, we might investigate the effects of shorter duration – so more intense shivering – to try and elucidate more precisely the optimum duration and intensity of shivering needed,” said Dr. Sellers.
“Our findings are promising and may have important health implications. In future studies, we plan to assess the effect of shivering in adults with type 2 diabetes,” he concluded.
Dr. Seller and Dr. Krook have reported no relevant financial relationships.

House passes prior authorization bill, Senate path unclear
The path through the U.S. Senate is not yet certain for a bill intended to speed the prior authorization process of insurer-run Medicare Advantage plans, despite the measure having breezed through the House.
House leaders opted to move the Improving Seniors’ Timely Access to Care Act of 2021 (H.R. 3173) without requiring a roll-call vote. The measure was passed on Sept. 14 by a voice vote, an approach used in general with only uncontroversial measures that have broad support. The bill has 191 Democratic and 135 Republican sponsors, representing about three-quarters of the members of the House.
“There is no reason that patients should be waiting for medically appropriate care, especially when we know that this can lead to worse outcomes,” Rep. Earl Blumenauer (D-Ore.) said in a Sept. 14 speech on the House floor. “The fundamental promise of Medicare Advantage is undermined when people are delaying care, getting sicker, and ultimately costing Medicare more money.”
Rep. Greg Murphy, MD (R-N.C.), spoke on the House floor that day as well, bringing up cases he has seen in his own urology practice in which prior authorization delays disrupted medical care. One patient wound up in the hospital with abscess after an insurer denied an antibiotic prescription, Rep. Murphy said.
The Senate currently appears unlikely to move the prior authorization bill as a standalone measure. Instead, the bill may become part of a larger legislative package focused on health care that the Senate Finance Committee intends to prepare later this year.
The House-passed bill would require insurer-run Medicare plans to respond to expedited requests for prior authorization of services within 24 hours and to other requests within 7 days. This bill also would establish an electronic program for prior authorizations and mandate increased transparency as to how insurers use this tool.
CBO: Cost of change would be billions
In seeking to mandate changes in prior authorization, lawmakers likely will need to contend with the issue of a $16 billion cumulative cost estimate for the bill from the Congressional Budget Office. Members of Congress often seek to offset new spending by pairing bills that add to expected costs for the federal government with ones expected to produce savings.
Unlike Rep. Blumenauer, Rep. Murphy, and other backers of the prior authorization streamlining bill, CBO staff estimates that making the mandated changes would raise federal spending, inasmuch as there would be “a greater use of services.”
On Sept. 14, CBO issued a one-page report on the costs of the bill. The CBO report concerns only the bill in question, as is common practice with the office’s estimates.
Prior authorization changes would begin in fiscal 2025 and would add $899 million in spending, or outlays, that year, CBO said. The annual costs from the streamlined prior authorization practices through fiscal 2026 to 2032 range from $1.6 billion to $2.7 billion.
Looking at the CBO estimate against a backdrop of total Medicare Advantage costs may provide important context.
The increases in spending estimated by CBO may suggest that there would be little change in federal spending as a result of streamlining prior authorization practices. These estimates of increased annual spending of $1.6 billion–$2.7 billion are only a small fraction of the current annual cost of insurer-run Medicare, and they represent an even smaller share of the projected expense.
The federal government last year spent about $350 billion on insurer-run plans, excluding Part D drug plan payments, according to the Medicare Advisory Payment Commission (MedPAC).
As of 2021, about 27 million people were enrolled in these plans, accounting for about 46% of the total Medicare population. Enrollment has doubled since 2010, MedPAC said, and it is expected to continue to grow. By 2027, insurer-run Medicare could cover 50% of the program’s population, a figure that may reach 53% by 2031.
Federal payments to these plans will accelerate in the years ahead as insurers attract more people eligible for Medicare as customers. Payments to these private health plans could rise from an expected $418 billion this year to $940.6 billion by 2031, according to the most recent Medicare trustees report.
Good intentions, poor implementation?
Insurer-run Medicare has long enjoyed deep bipartisan support in Congress. That’s due in part to its potential for reducing spending on what are considered low-value treatments, or ones considered unlikely to provide a significant medical benefit, but Rep. Blumenauer is among the members of Congress who see insurer-run Medicare as a path for preserving the giant federal health program. Traditional Medicare has far fewer restrictions on services, which sometimes opens a path for tests and treatments that offer less value for patients.
“I believe that the way traditional fee-for-service Medicare operates is not sustainable and that Medicare Advantage is one of the tools we can use to demonstrate how we can incentivize value,” Rep. Blumenauer said on the House floor. “But this is only possible when the program operates as intended. I have been deeply concerned about the reports of delays in care” caused by the clunky prior authorization processes.
He highlighted a recent report from the internal watchdog group for the Department of Health & Human Services that raises concerns about denials of appropriate care. About 18% of a set of payment denials examined by the Office of Inspector General of HHS in April actually met Medicare coverage rules and plan billing rules.
“For patients and their families, being told that you need to wait longer for care that your doctor tells you that you need is incredibly frustrating and frightening,” Rep. Blumenauer said. “There’s no comfort to be found in the fact that your insurance company needs time to decide if your doctor is right.”
Trends in prior authorization
The CBO report does not provide detail on what kind of medical spending would increase under a streamlined prior authorization process in insurer-run Medicare plans.
From trends reported in prior authorization, though, two factors could be at play in what appear to be relatively small estimated increases in Medicare spending from streamlined prior authorization.
The work already underway to create less burdensome electronic systems for these requests, such as the Fast Prior Authorization Technology Highway initiative run by the America’s Health Insurance Plans trade association.
The other factor could be the number of cases in which prior authorization merely causes delays in treatments and tests and thus simply postpones spending while adding to clinicians’ administrative work.
An analysis of prior authorization requests for dermatologic practices affiliated with the University of Utah may represent an extreme example. In a report published in JAMA Dermatology in 2020, researchers described what happened with requests made during 1 month, September 2016.
The approval rate for procedures was 99.6% – 100% (95 of 95) for Mohs surgery, and 96% (130 of 131, with 4 additional cases pending) for excisions. These findings supported calls for simplifying prior authorization procedures, “perhaps first by eliminating unnecessary PAs [prior authorizations] and appeals,” Aaron M. Secrest, MD, PhD, of the University of Utah, Salt Lake City, and coauthors wrote in the article.
Still, there is some evidence that insurer-run Medicare policies reduce the use of low-value care.
In a study published in JAMA Health Forum, Emily Boudreau, PhD, of insurer Humana Inc, and coauthors from Tufts University, Boston, and the University of Pennsylvania, Philadelphia investigated whether insurer-run Medicare could do a better job in reducing the amount of low-value care delivered than the traditional program. They analyzed a set of claims data from 2017 to 2019 for people enrolled in insurer-run and traditional Medicare.
They reported a rate of 23.07 low-value services provided per 100 people in insurer-run Medicare, compared with 25.39 for those in traditional Medicare. Some of the biggest differences reported in the article were in cancer screenings for older people.
As an example, the U.S. Preventive Services Task Force recommends that women older than 65 years not be screened for cervical cancer if they have undergone adequate screening in the past and are not at high risk for cervical cancer. There was an annual count of 1.76 screenings for cervical cancer per 100 women older than 65 in the insurer-run Medicare group versus 3.18 for those in traditional Medicare.
The Better Medicare Alliance issued a statement in favor of the House passage of the Improving Seniors’ Timely Access to Care Act.
In it, the group said the measure would “modernize prior authorization while protecting its essential function in facilitating safe, high-value, evidence-based care.” The alliance promotes use of insurer-run Medicare. The board of the Better Medicare Alliance includes executives who serve with firms that run Advantage plans as well as medical organizations and universities.
“With studies showing that up to one-quarter of all health care expenditures are wasted on services with no benefit to the patient, we need a robust, next-generation prior authorization program to deter low-value, and even harmful, care while protecting access to needed treatment and effective therapies,” said A. Mark Fendrick, MD, director of the University of Michigan’s Center for Value-Based Insurance Design in Ann Arbor, in a statement issued by the Better Medicare Alliance. He is a member of the group’s council of scholars.
On the House floor on September 14, Rep. Ami Bera, MD (D-Calif.), said he has heard from former colleagues and his medical school classmates that they now spend as much as 40% of their time on administrative work. These distractions from patient care are helping drive physicians away from the practice of medicine.
Still, the internist defended the basic premise of prior authorization while strongly appealing for better systems of handling it.
“Yes, there is a role for prior authorization in limited cases. There is also a role to go back and retrospectively look at how care is being delivered,” Rep. Bera said. “But what is happening today is a travesty. It wasn’t the intention of prior authorization. It is a prior authorization process gone awry.”

As an example, the U.S. Preventive Services Task Force recommends that women older than 65 years not be screened for cervical cancer if they have undergone adequate screening in the past and are not at high risk for cervical cancer. There was an annual count of 1.76 screenings for cervical cancer per 100 women older than 65 in the insurer-run Medicare group versus 3.18 for those in traditional Medicare.
The Better Medicare Alliance issued a statement in favor of the House passage of the Improving Seniors’ Timely Access to Care Act.
In it, the group said the measure would “modernize prior authorization while protecting its essential function in facilitating safe, high-value, evidence-based care.” The alliance promotes use of insurer-run Medicare. The board of the Better Medicare Alliance includes executives who serve with firms that run Advantage plans as well as medical organizations and universities.
“With studies showing that up to one-quarter of all health care expenditures are wasted on services with no benefit to the patient, we need a robust, next-generation prior authorization program to deter low-value, and even harmful, care while protecting access to needed treatment and effective therapies,” said A. Mark Fendrick, MD, director of the University of Michigan’s Center for Value-Based Insurance Design in Ann Arbor, in a statement issued by the Better Medicare Alliance. He is a member of the group’s council of scholars.
On the House floor on September 14, Rep. Ami Bera, MD (D-Calif.), said he has heard from former colleagues and his medical school classmates that they now spend as much as 40% of their time on administrative work. These distractions from patient care are helping drive physicians away from the practice of medicine.
Still, the internist defended the basic premise of prior authorization while strongly appealing for better systems of handling it.
“Yes, there is a role for prior authorization in limited cases. There is also a role to go back and retrospectively look at how care is being delivered,” Rep. Bera said. “But what is happening today is a travesty. It wasn’t the intention of prior authorization. It is a prior authorization process gone awry.”
AGA’s stance: This is a huge victory for patients! Advocating for prior authorization reform has been AGA’s top priority. Learn more about prior authorization and how it impacts gastroenterology on the AGA website.

Mothers’ diabetes linked to ADHD in their children
Children born to women who develop diabetes either before or during their pregnancy could be at risk for developing attention-deficit/hyperactivity disorder, data from a large multinational cohort study appear to show.
Considering more than 4.5 million mother-child pairs, it was found that children whose mothers had diabetes around the time of their pregnancy were 16% more likely to have ADHD diagnosed than were those whose mothers did not.
An increased risk was seen regardless of the type of diabetes, and regardless of whether or not the diabetes was present before or appeared during the pregnancy.
“We found a small increased risk of ADHD in children born to mothers with diabetes, including pregestational diabetes and gestational diabetes,” Carolyn Cesta, PhD, reported at the annual meeting of the European Association for the Study of Diabetes.
Dr. Cesta, a postdoctoral researcher in the Centre for Pharmacoepidemiology at the Karolinska Institutet in Stockholm noted that the effect sizes seen were lower than had been reported previously.
“This may be because we adjusted for a large number of covariates, including maternal ADHD and psychiatric disorders,” Dr. Cesta said.
ADHD and diabetes
“Previous studies have reported an increase in the risk of ADHD in children born to mothers with diabetes,” explained Dr. Cesta.
However, “these studies have been limited by the use of self-reported data, small sample sizes, lack of adjustment for important confounders, and they’re often limited to [White] populations,” she added. “There’s a lot of heterogeneity between these studies,” she said.
To try to iron out the differences seen in the prior studies, Dr. Cesta and associates looked at data from several databases based in Hong Kong (Clinical Data Analysis and Reporting System), four Nordic countries (Population Health Registers for Finland, Iceland, Norway, and Sweden), and Taiwan (National Health Insurance Database).
To create the matched mother-child pairs, the databases were searched to find women who had children born between 2001 and 2018, and who had follow-up data available up to 2020 on not only their diabetes status and child’s ADHD status, but also other parameters, such as other maternal diagnoses, maternal medications, and a host of sociodemographic factors.
More than 24 potentially confounding or covariates were considered in the analysis, which used Cox proportional hazard regression modeling and propensity score analysis to calculate hazard ratios with 95% confidence intervals.
“We looked at whether [mothers] had a diagnosis of ADHD themselves, or other psychiatric disorders, because there is high heritability for these disorders,” Dr. Cesta said, indicating that all bases had endeavored to be covered.
Main findings
Results showed some differences in the prevalence of diabetes and ADHD between the three cohorts used in the analysis. The prevalence of any maternal diabetes ranged from 8.8% in the Hong Kong cohort to 3.3% in the Taiwan cohort, with a prevalence of 6.8% for the Nordic cohort.
Rates of pregestational diabetes were lowest in the Taiwan and Hong Kong cohorts, at 0.2% and 0.5%, respectively, and 2.2% in the Nordic cohort. Gestational diabetes rates were a respective 3.1%, 7.8%, and 4.6%.
The highest rate of ADHD in children was seen in the Taiwan cohort, at 9.6%, followed by 4.2% for the Hong Kong cohort, and 2.6% for the Nordic cohort.
The hazard ratio for having childhood ADHD was 1.16 when comparing any maternal diabetes to no maternal diabetes, 1.40 comparing mothers with and without pregestational diabetes, and a respective 1.36 and 1.37 comparing those with and without type 1 diabetes, and those with and without type 2 diabetes.
The HR for childhood ADHD comparing mothers with and without gestational diabetes was 1.13.
“Within the analysis for gestational diabetes, we had enough numbers to look at siblings that are discordant for maternal gestational diabetes,” Dr. Cesta said. Essentially “we’re comparing two siblings from the same mother, one that was exposed to gestational diabetes, one that wasn’t,” she explained.
Interestingly there was no association between ADHD and maternal gestational diabetes in the sibling analysis (HR, 1.0).
“When it comes to gestational diabetes, the evidence from our sibling analysis indicate that the association may actually be confounded by shared genetics and environmental factors,” said Dr. Cesta.
“So, future studies should explore the role of specific genetic factors in glycemic control during pregnancy and the relationship between maternal diabetes and ADHD.”
Answering long-standing questions
These data will help a lot in answering questions that clinicians have been asking themselves a long time, commented Jardena Puder, MD, who chaired the session.
“It still remains a bit puzzling that genetic and environmental factors could be responsible, if you see the same effect in type 1 [diabetes], and in type 2 [diabetes], and gestational diabetes,” said Dr. Puder, who is an endocrinologist and diabetologist at the woman-mother-child department at the Vaud University Hospital Center, Lausanne, Switzerland.
Type 1 and type 2 are “very distinct” in terms of the genetic and environmental factors involved, “so, the fact that you see [the effect] in both remains a bit puzzling,” said Dr. Puder.
“I wish we had the numbers to be able to do the sibling analysis for type 1 and type 2, just to see if we could tease anything out,” said Dr. Cesta.
“I do think this is part of the bigger question of what the relationship is between, like, metabolic disorders and psychiatric disorders, because even outside of pregnancy, we see that there’s often a comorbidity with them. So, it’s a good point.”
The next step is to look at the role of treatment and what effects glycemic control might have on the small, but still apparent, association between maternal diabetes and ADHD.
The study had multiple funders including the Hong Kong Research Grant Council, NordForsk, the Research Council of Norway, the Norwegian ADHD Research Network, the Hong Kong Innovation and Technology Commission, and European Horizon 2020.
Dr. Cesta had no conflicts of interest to disclose. Dr. Puder chaired the session in which the findings were presented and made no specific disclosures.

FDA warns against cooking chicken in NyQuil
Called the “sleepy chicken challenge,” the trend tells people to cook chicken in NyQuil or similar over-the-counter cough and cold medications, which include ingredients such as acetaminophen, dextromethorphan, and doxylamine.
“The challenge sounds silly and unappetizing – and it is. But it could also be very unsafe,” the FDA said. “Boiling a medication can make it much more concentrated and change its properties in other ways.”
Even if someone doesn’t plan to eat the chicken, inhaling the vapors of the medication while it cooks could cause high levels of the drug to enter the body.
“It could also hurt your lungs,” the FDA said. “Put simply: Someone could take a dangerously high amount of the cough and cold medicine without even realizing it.”
This isn’t the first time that social media challenges involving medicine have gone viral. In a 2020 TikTok challenge, people were encouraged to take large doses of the allergy medicine diphenhydramine, called the “Benadryl challenge,” to cause hallucinations. The FDA received several reports of teens who were hospitalized or died, and it issued a warning about taking high doses of the drug.
“These video challenges, which often target youths, can harm people – and even cause death,” the FDA said. “Nonprescription (also called over-the-counter or OTC) drugs are readily available in many homes, making these challenges even more risky.”
In the latest warning, the FDA provided several ways for parents to make it less likely for children to do the social media challenges, such as locking up prescription and over-the-counter medications to prevent accidental overdoses. The FDA also encouraged parents and guardians to have open conversations with their children.
“Sit down with your children and discuss the dangers of misusing drugs and how social media trends can lead to real, sometimes irreversible, damage,” the FDA said. “Remind your children that overdoses can occur with OTC drugs as well as with prescription drugs.”
Following the FDA warning, the American Academy of Pediatrics also issued an advisory about social media trends. Some challenges, such as the ALS ice bucket challenge or the mannequin challenge, can be fun and positive activities. But medication-related challenges, such as the sleepy chicken and Benadryl challenges, can cause serious heart problems, seizures, coma, and even death.
“Teens’ brains are still developing. The part of the brain that handles rational thought, the prefrontal cortex, is not fully developed until the mid-20s,” the American Academy of Pediatrics said. “This means teens are naturally more impulsive and likely to act before thinking through all of the ramifications.”
Social media rewards outrageous behavior, it wrote, and the more outrageous the behavior, the more likely someone will get more engagement online.
“It’s a quick moving, impulsive environment, and the fear of losing out is real for teens,” the academy said. “What they will focus on is that a popular kid in class did this and got hundreds of likes and comments.”
The academy suggested that parents and guardians talk with teens about which challenges are trending on social media and at school.
“Sometimes kids are more willing to talk about their peers than themselves,” it said. “Asking questions about school trends, friends and fads may yield more answers than direct questions about their own activities.”

Telehealth effective in managing patients with movement disorders
Researchers presented their findings at the International Congress of Parkinson’s Disease and Movement Disorders.
Serving the underserved
One of the studies – from Kenya, Africa – documented a 2-year experience with telemedicine in a rural patient population.
Kenya suffers from a dearth of neurologists and movement disorder specialists. Most are based in the capital city of Nairobi, “leaving regions with a population of more than 30 million without access to their care,” wrote the study’s investigators. Internists with an interest in neurology usually manage the bulk of these patients.
Telemedicine has helped to bridge gaps between providers in this part of Africa.
Investigators in their study reviewed all cases of movement disorders at Meru Teaching and Referral Hospital and an affiliated clinic, Oregon Health Services, Meru, Kenya, during 2020 and 2021.
They also reviewed WhatsApp messaging, video calls via WhatsApp, patient videos, and phone calls to see how final diagnoses were arrived at using these platforms.
“For instance, a relative would send a video of a patient experiencing a tremor,” explained lead study author Bundi Karau, MD, a consultant physician. “We also shared the diagnostic challenges with experienced neurologists in Kenya and abroad by forwarding WhatsApp and recorded videos of the patients,” he added.
Telemedicine bridged the gap between rural doctors and patients in several ways. It enabled physicians to discuss cases with neurologists in and out of Kenya. “We were able to advise on medical management or further investigations in a more structured pattern and without spending months to make a diagnosis,” said Dr. Karau.
Patients no longer had to travel to Nairobi for care. “Where a direct link could be expensive or out of reach, we bridged this and consequently brought care closer to the patient,” he added.
More than 100 patients were diagnosed with a movement disorder and enrolled in care and follow-up during this 2-year time. Patients averaged about 62 years of age and more than 60% were male. Parkinson’s disease was the most common diagnosed condition (38.9%) followed by drug-induced movement disorders (30.6%), dystonia (11.1%), and functional movement disorders (11.1%).
Investigators found 3 cases of diabetic striatopathy, 8 cases of myoclonus, and 2 cases of Sydenham’s chorea.
Looking ahead, Dr. Karau and colleagues plan to do a cost benefit analysis vis-a-vis traditional physician visits and a trial model for follow-up visits for other neurological diseases.
Wearable devices and apps improve care
Moving from Africa to Greece, investigators in another study assessed the feasibility of using wearable devices to monitor symptoms in patients with Parkinson’s disease.
Such devices may enhance physical exams during virtual visits. Studies have shown that patients can commit to using such devices or mobile apps. What’s lacking is real-world data from everyday device usage, noted lead author George Rigas, PhD, and colleagues.
Fifty-two private physicians instructed a total of 133 patients to wear a device for Parkinson’s disease motor symptom telemonitoring for 1 week per month during waking hours.
Patients used a mobile app to report symptoms, medication, and nutrition adherence and to message their doctor.
The study team noticed that adherence rates stayed above 70% over a 12-month period. Medication and nutrition were among the most popular app features, an encouraging finding given that patients averaged 67 years of age.
“The high adherence percentage is significant, considering the target population and the early stage of telemedicine in Greece,” they concluded. Additional real-world data could help better inform longer-term adherence.
“These studies from all over the world demonstrate that we are only scratching the surface of the telehealth’s potential to improve care and the lives of individuals with Parkinson’s disease,” said Ray Dorsey, MD, a professor of neurology with the Center for Health + Technology at the University of Rochester (N.Y.).
Dr. Dorsey was not involved with the studies but has written and researched extensively on this topic.
Dr. Dorsey is a consultant for and has equity interests in Mediflix and Included Health, two digital health companies.

“For instance, a relative would send a video of a patient experiencing a tremor,” explained lead study author Bundi Karau, MD, a consultant physician. “We also shared the diagnostic challenges with experienced neurologists in Kenya and abroad by forwarding WhatsApp and recorded videos of the patients,” he added.
Telemedicine bridged the gap between rural doctors and patients in several ways. It enabled physicians to discuss cases with neurologists in and out of Kenya. “We were able to advise on medical management or further investigations in a more structured pattern and without spending months to make a diagnosis,” said Dr. Karau.
Patients no longer had to travel to Nairobi for care. “Where a direct link could be expensive or out of reach, we bridged this and consequently brought care closer to the patient,” he added.
More than 100 patients were diagnosed with a movement disorder and enrolled in care and follow-up during this 2-year time. Patients averaged about 62 years of age and more than 60% were male. Parkinson’s disease was the most common diagnosed condition (38.9%) followed by drug-induced movement disorders (30.6%), dystonia (11.1%), and functional movement disorders (11.1%).
Investigators found 3 cases of diabetic striatopathy, 8 cases of myoclonus, and 2 cases of Sydenham’s chorea.
Looking ahead, Dr. Karau and colleagues plan to do a cost benefit analysis vis-a-vis traditional physician visits and a trial model for follow-up visits for other neurological diseases.
Wearable devices and apps improve care
Moving from Africa to Greece, investigators in another study assessed the feasibility of using wearable devices to monitor symptoms in patients with Parkinson’s disease.
Such devices may enhance physical exams during virtual visits. Studies have shown that patients can commit to using such devices or mobile apps. What’s lacking is real-world data from everyday device usage, noted lead author George Rigas, PhD, and colleagues.
Fifty-two private physicians instructed a total of 133 patients to wear a device for Parkinson’s disease motor symptom telemonitoring for 1 week per month during waking hours.
Patients used a mobile app to report symptoms, medication, and nutrition adherence and to message their doctor.
The study team noticed that adherence rates stayed above 70% over a 12-month period. Medication and nutrition were among the most popular app features, an encouraging finding given that patients averaged 67 years of age.
“The high adherence percentage is significant, considering the target population and the early stage of telemedicine in Greece,” they concluded. Additional real-world data could help better inform longer-term adherence.
“These studies from all over the world demonstrate that we are only scratching the surface of the telehealth’s potential to improve care and the lives of individuals with Parkinson’s disease,” said Ray Dorsey, MD, a professor of neurology with the Center for Health + Technology at the University of Rochester (N.Y.).
Dr. Dorsey was not involved with the studies but has written and researched extensively on this topic.

Serving the underserved
One of the studies – from Kenya, Africa – documented a 2-year experience with telemedicine in a rural patient population.
Kenya suffers from a dearth of neurologists and movement disorder specialists. Most are based in the capital city of Nairobi, “leaving regions with a population of more than 30 million without access to their care,” wrote the study’s investigators. Internists with an interest in neurology usually manage the bulk of these patients.
Telemedicine has helped to bridge gaps between providers in this part of Africa.
