Why do some people escape infection that sickens others?
During the COVID-19 pandemic, we’ve seen this play out time and time again when whole families get sick except for one or two fortunate family members. And at so-called superspreader events that infect many, a lucky few typically walk away with their health intact. Did the virus never enter their bodies? Or do some people have natural resistance to pathogens they’ve never been exposed to before encoded in their genes?
Resistance to infectious disease is much more than a scientific curiosity and studying how it works can be a path to curb future outbreaks.
“In the event that we could identify what makes some people resistant, that immediately opens avenues for therapeutics that we could apply in all those other people who do suffer from the disease,” says András Spaan, MD, a microbiologist at Rockefeller University in New York.
Dr. Spaan is part of an international effort to identify genetic variations that spare people from becoming infected with SARS-CoV-2, the virus that causes COVID-19.
There’s far more research on what drives the tendency to get infectious diseases than on resistance to them. But a few researchers are investigating resistance to some of the world’s most common and deadly infectious diseases, and in a few cases, they’ve already translated these insights into treatments.
Perhaps the strongest example of how odd genes of just a few people can inspire treatments to help many comes from research on the human immunodeficiency virus (HIV), the virus that causes acquired immune deficiency syndrome (AIDS).
A genetic quirk
In the mid-1990s, several groups of researchers independently identified a mutation in a gene called CCR5 linked to resistance to HIV infection.
The gene encodes a protein on the surface of some white blood cells that helps set up the movement of other immune cells to fight infections. HIV, meanwhile, uses the CCR5 protein to help it enter the white blood cells that it infects.
The mutation, known as delta 32, results in a shorter than usual protein that doesn’t reach the surface of the cell. People who carry two copies of the delta 32 form of CCR5 do not have any CCR5 protein on the outside of their white blood cells.
Researchers, led by molecular immunologist Philip Murphy, MD, at the National Institute of Allergy and Infectious Diseases in Bethesda, Md, showed in 1997 that people with two copies of the mutation were unusually common among a group of men who were at especially high risk of HIV exposure, but had never contracted the virus. And out of more than 700 HIV-positive people, none carried two copies of CCR5 delta 32.
Pharmaceutical companies used these insights to develop drugs to block CCR5 and delay the development of AIDS. For instance, the drug maraviroc, marketed by Pfizer, was approved for use in HIV-positive people in 2007.
Only a few examples of this kind of inborn, genetically determined complete resistance to infection have ever been heard of. All of them involve cell-surface molecules that are believed to help a virus or other pathogen gain entry to the cell.
Locking out illness
“The first step for any intracellular pathogen is getting inside the cell. And if you’re missing the doorway, then the virus can’t accomplish the first step in its life cycle,” Dr. Murphy says. “Getting inside is fundamental.”
Changes in cell-surface molecules can also make someone more likely to have an infection or severe disease. One such group of cell-surface molecules that have been linked to both increasing and decreasing the risk of various infections are histo-blood group antigens. The most familiar members of this group are the molecules that define blood types A, B, and O.
Scientists have also identified one example of total resistance to infection involving these molecules. In 2003, researchers showed that people who lack a functional copy of a gene known as FUT2 cannot be infected with Norwalk virus, one of more than 30 viruses in the norovirus family that cause illness in the digestive tract.
The gene FUT2 encodes an enzyme that determines whether or not blood group antigens are found in a person’s saliva and other body fluids as well as on their red blood cells.
“It didn’t matter how many virus particles we challenged an individual with, if they did not have that first enzyme, they did not get infected,” says researcher Lisa Lindesmith, a virologist at the University of North Carolina in Chapel Hill.
No norovirus
Norwalk is a relatively rare type of norovirus. But FUT2 deficiency also provides some protection against the most common strains of norovirus, known as GII.4, which have periodically swept across the world over the past quarter-century. These illnesses take an especially heavy toll on children in the developing world, causing malnutrition and contributing to infant and child deaths.
But progress in translating these insights about genetic resistance into drugs or other things that could reduce the burden of noroviruses has been slow.
“The biggest barrier here is lack of ability to study the virus outside of humans,” Lindesmith says.
Noroviruses are very difficult to grow in the lab, “and there’s no small animal model of gastrointestinal illness caused by the viruses.”
We are clearly making giant strides in improving those skills,” says Lindesmith. “But we are just not quite there yet.”
In the years before COVID-19 emerged, tuberculosis was responsible for the largest number of annual worldwide deaths from an infectious disease. It’s a lung disease caused by the bacterium Mycobacterium tuberculosis, and it has been a pandemic for thousands of years.
Some 85%-95% of people with intact immune systems who are infected with TB control the infection and never get active lung disease. And some people who have intense, continuing exposure to the bacterium, which is spread through droplets and aerosols from people with active lung disease, apparently never become infected at all.
Thwarting uberculosis
Understanding the ways of these different forms of resistance could help in the search for vaccines, treatments, and other ways to fight tuberculosis, says Elouise Kroon, MD, a graduate student at Stellenbosch University in Cape Town, South Africa.
“What makes it particularly hard to study is the fact that there is no gold standard to measure infection,” she says. “So, what we do is infer infection from two different types of tests” -- a skin test and a blood test that measure different kinds of immune response to molecules from the bacterium.
Dr. Kroon and other researchers have studied resistance to infection by following people living in the same household as those with active lung disease or people who live and work in crowded conditions in high-risk communities. But not all such studies have used the same definition of so-called resisters, documented exposure in the same way, or followed up to ensure that people continue to test negative over the long term.
The best clue that has emerged from studies so far links resistance to infection to certain variations in immune molecules known as HLA class II antigens, says Marlo Möller, PhD, a professor in the TB Host Genetics Research Group at Stellenbosch University.
“That always seems to pop up everywhere. But the rest is not so obvious,” she says. “A lot of the studies don’t find the same thing. It’s different in different populations,” which may be a result of the long evolutionary history between tuberculosis and humans, as well as the fact that different strains of the bacterium are prevalent in different parts of the world.
COVID-19 is a much newer infectious disease, but teasing out how it contributes to both severe illness and resistance to infection is still a major task.
Overcoming COVID
Early in the pandemic, research by the COVID Human Genetic Effort, the international consortium that Dr. Spaan is part of, linked severe COVID-19 pneumonia to the lack of immune molecules known as type I interferons and to antibodies produced by the body that destroy these molecules. Together, these mechanisms explain about one-fifth of severe COVID-19 cases, the researchers reported in 2021.
A few studies by other groups have explored resistance to COVID-19 infection, suggesting that reduced risk of contracting the virus is tied to certain blood group factors. People with Type O blood appear to be at slightly reduced risk of infection, for example.
But the studies done so far are designed to find common genetic variations, which generally have a small effect on resistance. Now, genetic researchers are launching an effort to identify genetic resistance factors with a big effect, even if they are vanishingly rare.
The group is recruiting people who did not become infected with COVID-19 despite heavy exposure, such as those living in households where all the other members got sick or people who were exposed to a superspreader event but did not become ill. As with tuberculosis, being certain that someone has not been infected with the virus can be tricky, but the team is using several blood tests to home in on the people most likely to have escaped infection.
They plan to sequence the genomes of these people to identify things that strongly affect infection risk, then do more laboratory studies to try to tease out the means of resistance.
Their work is inspired by earlier efforts to uncover inborn resistance to infections, Dr. Spaan says. Despite the lack of known examples of such resistance, he is optimistic about the possibilities. Those earlier efforts took place in “a different epoch,” before there were rapid sequencing technologies, Dr. Spaan says.
“Now we have modern technologies to do this more systematically.”
The emergence of viral variants such as the Delta and Omicron COVID strains raises the stakes of the work, he continues.
“The need to unravel these inborn mechanisms of resistance to COVID has become even more important because of these new variants and the anticipation that we will have COVID with us for years.”

Comments & Controversies
A broken system
I was relieved to see your article “I have a dream … for psychiatry” (From the Editor,
Psychiatry does need better treatments. On the other hand, we do have many effective treatments that simply are not available to many.
This brings me to ask, how is it that overall psychiatric care is actually worse now than in, say, the late 20th century? There might have been fewer psychopharmacologic treatments available back then, but there was overall better access to care, and a largely intact system. For lower-functioning patients, such as those who are homeless or in jail, I do believe this is the case, as I will explain. But even higher-functioning private practice patients are affected by the shortage of psychiatrists.
In 2022, the system is broken. Funding is abysmal, and numerous psychiatric hospital closures across the United States have led to simply no reasonable local access for many.
Prisons and jails are the new treatment centers! As you have rightly pointed out, by being housed in prisons with violent criminals, severely mentally ill patients are subjected to physical and sexual abuse daily.
Laws meant to protect mentally ill individuals, such as psychiatric holds, are often not implemented. Severely mentally ill patients can meet the criteria to be categorized as a danger to self, danger to others, or gravely disabled, but can’t get crisis intervention. Abandoning these patients to the streets is, in part, fueling homelessness and drug addiction.
In my opinion, the broken system is the fundamental problem that needs to be solved. Although I long for novel treatments, if there were such breakthrough treatments available—as exciting as that may be—how could they be delivered effectively in our current broken system? In other words, how can these patients be treated with neuroscientific breakthrough treatments without the necessary psychiatric infrastructure? We are at such an extreme, I worry for our specialty.
In Karl Menninger’s The Crime of Punishment, one passage stuck with me: “I suspect that all the crimes committed by all the jailed criminals do not equal in total social damage that of the crimes committed against them.”1 I have often wondered how that relates to the criminalized mentally ill, who are punished daily by being in horrific, abusive, unsafe settings. What truly is their crime? Being mentally ill?
Given how the system is now engineered to throw these patients in prison and allow them to be abused instead of admitting them to a psychiatric hospital, one must wonder: How did this come to be? Could it go beyond stigma to actual hatred and contempt for these people? After all, as psychiatrists, the abuse is in plain sight.
Finally, I have often wondered why there has not been a robust psychiatric organizational response to the breakdown in access to patient care. I can only hope that one day there can be.
Dr. Nasrallah responds
Thank you for your comments on my editorial. I sense that you are quite frustrated with the current status of psychiatry, and are longing for improvements.
I do share some of your concerns about: 1) society turning a blind eye to the mentally ill (and I have written about that from the angle of tragically high suicide rate1); 2) the hatred and contempt embedded within stigma of serious mental disorders; 3) the deplorable criminalization and trans-institutionalization of our patients from state hospitals to jails and prisons; 4) the shortage of acute psychiatric beds in many communities because the wards were converted to highly lucrative, procedure-oriented programs; 5) the dysfunctional public mental health system; and 6) the need for new and novel treatments.
However, despite those challenges, I remain optimistic that the future of psychiatry is bright because I keep abreast of the stunning neuroscience advances every day that will be translated into psychiatric treatments in the future. I envision a time when these brain research breakthroughs will lead to important clinical applications, such as a better diagnostic system using biomarkers (precision psychiatry), not just a cluster of clinical symptoms, and to brave new therapeutic interventions with superior efficacy and better safety. I would not be surprised if psychiatry and neurology will again merge after decades of separation, and that will certainly erase much of the stigma of disorders of the mind, which is the virtual brain.
Please hang in there, and do not let your patients perceive a sense of resignation and pessimism about psychiatry. Both our patients and psychiatrists need to be uplifted by hope for a better future.

I do share some of your concerns about: 1) society turning a blind eye to the mentally ill (and I have written about that from the angle of tragically high suicide rate1); 2) the hatred and contempt embedded within stigma of serious mental disorders; 3) the deplorable criminalization and trans-institutionalization of our patients from state hospitals to jails and prisons; 4) the shortage of acute psychiatric beds in many communities because the wards were converted to highly lucrative, procedure-oriented programs; 5) the dysfunctional public mental health system; and 6) the need for new and novel treatments.
However, despite those challenges, I remain optimistic that the future of psychiatry is bright because I keep abreast of the stunning neuroscience advances every day that will be translated into psychiatric treatments in the future. I envision a time when these brain research breakthroughs will lead to important clinical applications, such as a better diagnostic system using biomarkers (precision psychiatry), not just a cluster of clinical symptoms, and to brave new therapeutic interventions with superior efficacy and better safety. I would not be surprised if psychiatry and neurology will again merge after decades of separation, and that will certainly erase much of the stigma of disorders of the mind, which is the virtual brain.
Please hang in there, and do not let your patients perceive a sense of resignation and pessimism about psychiatry. Both our patients and psychiatrists need to be uplifted by hope for a better future.
A broken system
I was relieved to see your article “I have a dream … for psychiatry” (From the Editor,
Psychiatry does need better treatments. On the other hand, we do have many effective treatments that simply are not available to many.
This brings me to ask, how is it that overall psychiatric care is actually worse now than in, say, the late 20th century? There might have been fewer psychopharmacologic treatments available back then, but there was overall better access to care, and a largely intact system. For lower-functioning patients, such as those who are homeless or in jail, I do believe this is the case, as I will explain. But even higher-functioning private practice patients are affected by the shortage of psychiatrists.
In 2022, the system is broken. Funding is abysmal, and numerous psychiatric hospital closures across the United States have led to simply no reasonable local access for many.
Prisons and jails are the new treatment centers! As you have rightly pointed out, by being housed in prisons with violent criminals, severely mentally ill patients are subjected to physical and sexual abuse daily.
Laws meant to protect mentally ill individuals, such as psychiatric holds, are often not implemented. Severely mentally ill patients can meet the criteria to be categorized as a danger to self, danger to others, or gravely disabled, but can’t get crisis intervention. Abandoning these patients to the streets is, in part, fueling homelessness and drug addiction.
In my opinion, the broken system is the fundamental problem that needs to be solved. Although I long for novel treatments, if there were such breakthrough treatments available—as exciting as that may be—how could they be delivered effectively in our current broken system? In other words, how can these patients be treated with neuroscientific breakthrough treatments without the necessary psychiatric infrastructure? We are at such an extreme, I worry for our specialty.
In Karl Menninger’s The Crime of Punishment, one passage stuck with me: “I suspect that all the crimes committed by all the jailed criminals do not equal in total social damage that of the crimes committed against them.”1 I have often wondered how that relates to the criminalized mentally ill, who are punished daily by being in horrific, abusive, unsafe settings. What truly is their crime? Being mentally ill?
Given how the system is now engineered to throw these patients in prison and allow them to be abused instead of admitting them to a psychiatric hospital, one must wonder: How did this come to be? Could it go beyond stigma to actual hatred and contempt for these people? After all, as psychiatrists, the abuse is in plain sight.
Finally, I have often wondered why there has not been a robust psychiatric organizational response to the breakdown in access to patient care. I can only hope that one day there can be.

‘Deaths of despair’ rising, but only in the U.S.
In the United States,
This is not the case in 16 other industrialized nations, however, including Canada, Australia, and Japan, where mortality rates are actually decreasing.
One likely reason is that other countries take better care of their citizens from cradle to grave, authors Peter Sterling, PhD, and Michael Platt, PhD, of the University of Pennsylvania, Philadelphia, wrote in a special communication in JAMA Psychiatry published online Feb. 2.
In the United States, individuals and families often struggle in isolation to navigate the life cycle, whereas other countries offer communal assistance to every life stage, and this support protects individuals and families in the long term, they noted.
The United States could solve this “health crisis” by adopting the best practices of these other nations, they wrote.
U.S. is an outlier
From an anthropological perspective, Dr. Sterling and Dr. Platt point out that “hunter-gatherers” prioritized food, comfort, and companionship. When one of these needs is unexpectedly met, the surprise triggers a pulse of the feel-good hormone dopamine.
However, much of modern life offers few opportunities for surprise and dopamine pulses.
“It is the difference between a day’s hard walk to finally encounter and kill a wild pig to feed the family and community versus a quick trip to aisle 7 to select a pork roast in plastic wrap,” Dr. Sterling and Dr. Platt noted.
The hunter-gatherers were far more physically active, and cardiovascular disease, diabetes, obesity, and hypertension were virtually unknown.
The small-scale societies of hunters and gatherers depended on strong family bonds and cooperation with community members.
Modern life is more isolating, often with hours spent alone in front of a computer screen.
Yet the lack of natural dopamine producers in modern society and the increased social isolation is not unique to the United States but holds across the board for industrialized nations.
So why has the United States suffered more deaths of despair?
Dr. Sterling and Dr. Platt assert that it comes down to public support other countries provide their citizens across the life span, from prenatal care and quality preschool and elementary school to affordable (or free) education beyond high school.
This support did not require “bloody revolutions, just simple agreements to prepay basic human needs from public funds collected as taxes,” Dr. Sterling and Dr. Platt noted.
By adopting some of the best practices pioneered by other wealthy nations, the United States could reduce despair and restore to many the will to live, they added.
However, they caution against the “medicalization” of every identified cause of rising death rates.
“Every symptom of despair has been defined as a disorder or dysregulation within the individual. This incorrectly frames the problem, forcing individuals to grapple on their own,” they wrote.
“It also emphasizes treatment by pharmacology, providing innumerable drugs for anxiety, depression, anger, psychosis, and obesity, plus new drugs to treat addictions to the old drugs. We cannot defeat despair solely with pills – to the contrary, pills will only deepen it,” they added.
Dr. Platt reported receiving grant support from the National Institutes of Health, the National Science Foundation, and the Charles E. Kaufman Foundation. He is cofounder of Cogwear and a scientific adviser to Neuroflow, Amplio, Blue Horizon International, and Progenity. Dr. Sterling has disclosed no relevant financial relationships.

“I didn’t want to meet you.” Dispelling myths about palliative care
The names of health care professionals and patients cited within the dialogue text have been changed to protect their privacy.
but over the years I have come to realize that she was right – most people, including many within health care, don’t have a good appreciation of what palliative care is or how it can help patients and health care teams.
A recent national survey about cancer-related health information found that of more than 1,000 surveyed Americans, less than 30% professed any knowledge of palliative care. Of those who had some knowledge of palliative care, around 30% believed palliative care was synonymous with hospice.1 Another 15% believed that a patient would have to give up cancer-directed treatments to receive palliative care.1
It’s not giving up
This persistent belief that palliative care is equivalent to hospice, or is tantamount to “giving up,” is one of the most commonly held myths I encounter in everyday practice.
I knock on the exam door and walk in.
A small, trim woman in her late 50s is sitting in a chair, arms folded across her chest, face drawn in.
“Hi,” I start. “I’m Sarah, the palliative care nurse practitioner who works in this clinic. I work closely with Dr. Smith.”
Dr. Smith is the patient’s oncologist.
“I really didn’t want to meet you,” she says in a quiet voice, her eyes large with concern.
I don’t take it personally. Few patients really want to be in the position of needing to meet the palliative care team.
“I looked up palliative care on Google and saw the word hospice.”
“Yeah,” I say. “I hear that a lot. Well, I can reassure you that this isn’t hospice.
In this clinic, our focus is on your cancer symptoms, your treatment side effects, and your quality of life.”
She looks visibly relieved. “Quality of life,” she echoes. “I need more of that.”
“OK,” I say. “So, tell me what you’re struggling with the most right now.”
That’s how many palliative care visits start. I actually prefer if patients haven’t heard of palliative care because it allows me to frame it for them, rather than having to start by addressing a myth or a prior negative experience. Even when patients haven’t had a negative experience with palliative care per se, typically, if they’ve interacted with palliative care in the past, it’s usually because someone they loved died in a hospital setting and it is the memory of that terrible loss that becomes synonymous with their recollection of palliative care.
Many patients I meet have never seen another outpatient palliative care practitioner – and this makes sense – we are still too few and far between. Most established palliative care teams are hospital based and many patients seen in the community do not have easy access to palliative care teams where they receive oncologic care.2 As an embedded practitioner, I see patients in the same exam rooms and infusion centers where they receive their cancer therapies, so I’m effectively woven into the fabric of their oncology experience. Just being there in the cancer center allows me to be in the right place at the right time for the right patients and their care teams.
More than pain management
Another myth I tend to dispel a lot is that palliative care is just a euphemism for “pain management.” I have seen this less lately, but still occasionally in the chart I’ll see documented in a note, “patient is seeing palliative/pain management,” when a patient is seeing me or one of my colleagues. Unfortunately, when providers have limited or outdated views of what palliative care is or the value it brings to patient-centered cancer care, referrals to palliative care tend to be delayed.3
“I really think Ms. Lopez could benefit from seeing palliative care,” an oncology nurse practitioner says to an oncologist.
I’m standing nearby, about to see another patient in one of the exam rooms in our clinic.
“But I don’t think she’s ready. And besides, she doesn’t have any pain,” he says.
He turns to me quizzically. “What do you think?”
“Tell me about the patient,” I ask, taking a few steps in their direction.
“Well, she’s a 64-year-old woman with metastatic cancer.
She has a really poor appetite and is losing some weight.
Seems a bit down, kind of pessimistic about things.
Her scan showed some new growth, so guess I’m not surprised by that.”
“I might be able to help her with the appetite and the mood changes.
I can at least talk with her and see where she’s at,” I offer.
“Alright,” he says. “We’ll put the palliative referral in.”
He hesitates. “But are you sure you want to see her?
She doesn’t have any pain.” He sounds skeptical.
“Yeah, I mean, it sounds like she has symptoms that are bothering her, so I’d be happy to see her. She sounds completely appropriate for palliative care.”
I hear this assumption a lot – that palliative care is somehow equivalent to pain management and that unless a patient’s pain is severe, it’s not worth referring the patient to palliative care. Don’t get me wrong – we do a lot of pain management, but at its heart, palliative care is an interdisciplinary specialty focused on improving or maintaining quality of life for people with serious illness. Because the goal is so broad, care can take many shapes.4
In addition to pain, palliative care clinicians commonly treat nausea, shortness of breath, constipation or diarrhea, poor appetite, fatigue, anxiety, depression, and insomnia.
Palliative care is more than medical or nursing care
A related misconception about palliative care held by many lay people and health care workers alike is that palliative care is primarily medical or nursing care focused mostly on alleviating physical symptoms such as pain or nausea. This couldn’t be further from the truth.
We’ve been talking for a while.
Ms. Lopez tells me about her struggles to maintain her weight while undergoing chemotherapy. She has low-grade nausea that is impacting her ability and desire to eat more and didn’t think that her weight loss was severe enough to warrant taking medication.
We talk about how she may be able to use antinausea medication sparingly to alleviate nausea while also limiting side effects from the medications—which was a big concern for her.
I ask her what else is bothering her.
She tells me that she has always been a strong Catholic and even when life has gotten tough, her faith was never shaken – until now.
She is struggling to understand why she ended up with metastatic cancer at such a relatively young age—why would God do this to her?
She had plans for retirement that have since evaporated in the face of a foreshortened life.
Why did this happen to her of all people? She was completely healthy until her diagnosis.
Her face is wet with tears.
We talk a little about how a diagnosis like this can change so much of a person’s life and identity. I try to validate her experience. She’s clearly suffering from a sense that her life is not what she expected, and she is struggling to integrate how her future looks at this point.
I ask her what conversations with her priest have been like.
At this point you may be wondering where this conversation is going. Why are we talking about Ms. Lopez’s religion? Palliative care is best delivered through high functioning interdisciplinary teams that can include other supportive people in a patient’s life. We work in concert to try to bring comfort to a patient and their family.4 That support network can include nurses, physicians, social workers, and chaplains. In this case, Ms. Lopez had not yet reached out to her priest. She hasn’t had the time or energy to contact her priest given her symptoms.
“Can I contact your priest for you?
Maybe he can visit or call and chat with you?”
She nods and wipes tears away.
“That would be really nice,” she says. “I’d love it if he could pray with me.”
A few hours after the visit, I call Ms. Lopez’s priest.
I ask him to reach out to her and about her request for prayer.
He says he’s been thinking about her and that her presence has been missed at weekly Mass. He thanks me for the call and says he’ll call her tomorrow.
I say my own small prayer for Ms. Lopez and head home, the day’s work completed.
Sarah D'Ambruoso was born and raised in Maine. She completed her undergraduate and graduate nursing education at New York University and UCLA, respectively, and currently works as a palliative care nurse practitioner in an oncology clinic in Los Angeles.

Her scan showed some new growth, so guess I’m not surprised by that.”
“I might be able to help her with the appetite and the mood changes.
I can at least talk with her and see where she’s at,” I offer.
“Alright,” he says. “We’ll put the palliative referral in.”
He hesitates. “But are you sure you want to see her?
She doesn’t have any pain.” He sounds skeptical.
“Yeah, I mean, it sounds like she has symptoms that are bothering her, so I’d be happy to see her. She sounds completely appropriate for palliative care.”
I hear this assumption a lot – that palliative care is somehow equivalent to pain management and that unless a patient’s pain is severe, it’s not worth referring the patient to palliative care. Don’t get me wrong – we do a lot of pain management, but at its heart, palliative care is an interdisciplinary specialty focused on improving or maintaining quality of life for people with serious illness. Because the goal is so broad, care can take many shapes.4
In addition to pain, palliative care clinicians commonly treat nausea, shortness of breath, constipation or diarrhea, poor appetite, fatigue, anxiety, depression, and insomnia.
Palliative care is more than medical or nursing care
A related misconception about palliative care held by many lay people and health care workers alike is that palliative care is primarily medical or nursing care focused mostly on alleviating physical symptoms such as pain or nausea. This couldn’t be further from the truth.
We’ve been talking for a while.
Ms. Lopez tells me about her struggles to maintain her weight while undergoing chemotherapy. She has low-grade nausea that is impacting her ability and desire to eat more and didn’t think that her weight loss was severe enough to warrant taking medication.
We talk about how she may be able to use antinausea medication sparingly to alleviate nausea while also limiting side effects from the medications—which was a big concern for her.
I ask her what else is bothering her.
She tells me that she has always been a strong Catholic and even when life has gotten tough, her faith was never shaken – until now.
She is struggling to understand why she ended up with metastatic cancer at such a relatively young age—why would God do this to her?
She had plans for retirement that have since evaporated in the face of a foreshortened life.
Why did this happen to her of all people? She was completely healthy until her diagnosis.
Her face is wet with tears.
We talk a little about how a diagnosis like this can change so much of a person’s life and identity. I try to validate her experience. She’s clearly suffering from a sense that her life is not what she expected, and she is struggling to integrate how her future looks at this point.
I ask her what conversations with her priest have been like.
At this point you may be wondering where this conversation is going. Why are we talking about Ms. Lopez’s religion? Palliative care is best delivered through high functioning interdisciplinary teams that can include other supportive people in a patient’s life. We work in concert to try to bring comfort to a patient and their family.4 That support network can include nurses, physicians, social workers, and chaplains. In this case, Ms. Lopez had not yet reached out to her priest. She hasn’t had the time or energy to contact her priest given her symptoms.
“Can I contact your priest for you?
Maybe he can visit or call and chat with you?”
She nods and wipes tears away.
“That would be really nice,” she says. “I’d love it if he could pray with me.”
A few hours after the visit, I call Ms. Lopez’s priest.
I ask him to reach out to her and about her request for prayer.
He says he’s been thinking about her and that her presence has been missed at weekly Mass. He thanks me for the call and says he’ll call her tomorrow.
I say my own small prayer for Ms. Lopez and head home, the day’s work completed.

The names of health care professionals and patients cited within the dialogue text have been changed to protect their privacy.
but over the years I have come to realize that she was right – most people, including many within health care, don’t have a good appreciation of what palliative care is or how it can help patients and health care teams.
A recent national survey about cancer-related health information found that of more than 1,000 surveyed Americans, less than 30% professed any knowledge of palliative care. Of those who had some knowledge of palliative care, around 30% believed palliative care was synonymous with hospice.1 Another 15% believed that a patient would have to give up cancer-directed treatments to receive palliative care.1
It’s not giving up
This persistent belief that palliative care is equivalent to hospice, or is tantamount to “giving up,” is one of the most commonly held myths I encounter in everyday practice.
I knock on the exam door and walk in.
A small, trim woman in her late 50s is sitting in a chair, arms folded across her chest, face drawn in.
“Hi,” I start. “I’m Sarah, the palliative care nurse practitioner who works in this clinic. I work closely with Dr. Smith.”
Dr. Smith is the patient’s oncologist.
“I really didn’t want to meet you,” she says in a quiet voice, her eyes large with concern.
I don’t take it personally. Few patients really want to be in the position of needing to meet the palliative care team.
“I looked up palliative care on Google and saw the word hospice.”
“Yeah,” I say. “I hear that a lot. Well, I can reassure you that this isn’t hospice.
In this clinic, our focus is on your cancer symptoms, your treatment side effects, and your quality of life.”
She looks visibly relieved. “Quality of life,” she echoes. “I need more of that.”
“OK,” I say. “So, tell me what you’re struggling with the most right now.”
That’s how many palliative care visits start. I actually prefer if patients haven’t heard of palliative care because it allows me to frame it for them, rather than having to start by addressing a myth or a prior negative experience. Even when patients haven’t had a negative experience with palliative care per se, typically, if they’ve interacted with palliative care in the past, it’s usually because someone they loved died in a hospital setting and it is the memory of that terrible loss that becomes synonymous with their recollection of palliative care.
Many patients I meet have never seen another outpatient palliative care practitioner – and this makes sense – we are still too few and far between. Most established palliative care teams are hospital based and many patients seen in the community do not have easy access to palliative care teams where they receive oncologic care.2 As an embedded practitioner, I see patients in the same exam rooms and infusion centers where they receive their cancer therapies, so I’m effectively woven into the fabric of their oncology experience. Just being there in the cancer center allows me to be in the right place at the right time for the right patients and their care teams.
More than pain management
Another myth I tend to dispel a lot is that palliative care is just a euphemism for “pain management.” I have seen this less lately, but still occasionally in the chart I’ll see documented in a note, “patient is seeing palliative/pain management,” when a patient is seeing me or one of my colleagues. Unfortunately, when providers have limited or outdated views of what palliative care is or the value it brings to patient-centered cancer care, referrals to palliative care tend to be delayed.3
“I really think Ms. Lopez could benefit from seeing palliative care,” an oncology nurse practitioner says to an oncologist.
I’m standing nearby, about to see another patient in one of the exam rooms in our clinic.
“But I don’t think she’s ready. And besides, she doesn’t have any pain,” he says.
He turns to me quizzically. “What do you think?”
“Tell me about the patient,” I ask, taking a few steps in their direction.
“Well, she’s a 64-year-old woman with metastatic cancer.
She has a really poor appetite and is losing some weight.
Seems a bit down, kind of pessimistic about things.
Her scan showed some new growth, so guess I’m not surprised by that.”

Lipedema: A potentially devastating, often unrecognized disease
” according to C. William Hanke, MD, MPH.
“This disease is well known in Europe, especially in the Netherlands, Germany, and Austria, but in this country, I believe most dermatologists have never heard of it,” Dr. Hanke said at the ODAC Dermatology, Aesthetic & Surgical Conference.
Clinically, patients with lipedema – also known as “two-body syndrome” – present with a symmetric, bilateral increase in subcutaneous fat, with “cuffs of fat” around the ankles. It usually affects the legs and thighs; the hands and feet are not affected.
“From the waist on up, the body looks like one person, and from the waist on down, it looks like an entirely different person,” said Dr. Hanke, a dermatologist who is program director for the micrographic surgery and dermatologic oncology fellowship training program at Ascension St. Vincent Hospital in Indianapolis. “Just think of the difficulty that the person has with their life in terms of buying clothes or social interactions. This is a devastating problem.”
Lipedema almost always affects women and is progressive from puberty. “Characteristically, patients have pain and bruise easily in the areas of lipedema,” said Dr. Hanke, who has served as president of the American Academy of Dermatology, the American Society for Dermatologic Surgery, the American College of Mohs Surgery, and the International Society for Dermatologic Surgery. The affected areas are painful to touch, making exercise uncomfortable for patients, he said.
Lipedema can be masked by obesity, “so, if you superimpose generalized obesity on lipedema, you have an even more difficult problem,” he added. “A physician who doesn’t understand the disease may perform standard nontumescent liposuction under general anesthesia, with cannulas, which traumatize lipedematous fat. Thereby, a patient with lipedema can then be inadvertently transformed into a patient with lympholipedema. Then you’ve got even an even worse problem.”
One might think that the rate of diabetes would be high among lipedema patients, “but diabetes is essentially nonexistent in this group,” he continued. However, patients with lipedema “may develop hypothyroidism, venous disease, joint pain, and fibrosis in the fat as the disease progresses.”
Lipedema stages, treatment
Lipedema is defined by three clinical stages: Stage one is characterized by an enlarged subcutaneous fat department, but the skin surface is smooth. In stage 2, the skin surface becomes wavy with irregularities and dents, and in stage 3, patients develop large deforming nodules and hanging flaps.
“If we can diagnose lipedema in the early stages and perform tumescent liposuction using tumescent local anesthesia, we can prevent the progression of the disease,” Dr. Hanke said. For patients who meet criteria for tumescent liposuction, three to six treatments may be required for stage 3 disease. “Tumescent local anesthesia should be used, because liposuction using tumescent local anesthesia is atraumatic to fat,” he said. “Usually, the most painful areas are treated first.”
In a single-center study from Germany that followed 85 patients who underwent tumescent liposuction for lipedema, researchers found that improvements in pain, bruising, and mobility were sustained at 4 and 8 years following the procedure. Patient quality of life and cosmetic appearance were also sustained.
In terms of liposuction’s cosmetic effects, “the goal of liposuction in lipedema patients is different,” Dr. Hanke said. “The goal is to get these people moving again, stabilize their weight, and minimize progression of the disease. Cosmetic improvement is secondary.”
A more recent follow-up study of 60 patients from the same single-center German study showed that the positive effects of liposuction lasted 12 years postoperatively without relevant progression of disease.
Following the first International Consensus Conference on Lipedema in Vienna in 2017, Dr. Hanke and colleagues published guidelines on preventing progression of lipedema with liposuction using tumescent local anesthesia.
“If patients with lipedema gain weight, the problem becomes even worse,” he said. “A sensible diet and nontraumatic exercise like water aerobics is ideal. If patients pursue yo-yo dieting, more and more fat stays in the legs after each cycle. Sometimes I’ll refer overweight patients with lipedema for a bariatric surgery consult.”
Dr. Hanke noted that Karen Herbst, MD, PhD, an endocrinologist at the University of Arizona, Tucson, who is widely considered an expert on the medical management of lipedema, has a website on lipedema care.
Dr. Hanke reported having no financial conflicts related to his presentation.

Scleral Plaques in Nephrogenic Systemic Fibrosis
To the Editor:
A 44-year-old man with a history of systemic lupus erythematosus (SLE) complicated by lupus nephritis, end-stage renal disease, and antiphospholipid syndrome was evaluated for progressive skin tightening over the last 3 years, predominantly on the hands but also involving the feet, legs, and arms. Physical examination revealed multiple flesh-colored to hypopigmented, bound-down, indurated, fissured plaques over the distal upper and lower extremities, most prominent over the hands (Figure 1). Yellow plaques appeared on the lateral sclera of both eyes (Figure 2). A diagnosis of nephrogenic systemic fibrosis (NSF) was supported by typical findings on punch biopsy, including a proliferation of dermal fibroblasts with thickened collagen bundles and mucin deposition.
Nephrogenic systemic fibrosis, also known as nephrogenic fibrosing dermopathy, is characterized by fibrotic plaques and nodules that tend to be bilateral.1 The chronic course of this disease often is accompanied by flexion contractures. Yellow scleral plaques caused by calcium phosphate deposition are present in up to 75% of cases and are more specific to a diagnosis of NSF in patients younger than 45 years.1,2 A strong association exists between NSF and gadolinium contrast agents in patients with acute renal failure; our patient later confirmed multiple gadolinium exposures years prior. Deposits of gadolinium have even been found in NSF skin lesions.2

Men with hypersexual disorder may have oxytocin overload
Men with hypersexual disorder showed higher levels of oxytocin in their blood than did healthy control men without the disorder, in a study with 102 participants.
Hypersexual disorder (HD) is characterized by “excessive and persistent sexual behaviors in relation to various mood states, with an impulsivity component and experienced loss of control,” John Flanagan, MD, of the Karolinska Institutet in Stockholm and colleagues wrote. Although HD is not included as a separate diagnosis in the current DSM, the similar disorder of compulsive sexual behavior is included in the ICD.
Data on the pathophysiology of HD are limited, although a previous study by corresponding author Andreas Chatzittofis, MD, and colleagues showed evidence of neuroendocrine dysregulation in men with HD, and prompted the current study to explore the possible involvement of the oxytocinergic system in HD.
In the current study, published in the Journal of Clinical Endocrinology & Metabolism, the researchers identified 64 men with HD and 38 healthy male controls. The patients were help-seeking men older than 18 years diagnosed with HD who presented to a single center in Sweden during 2013-2014. The men were included in a randomized clinical trial of cognitive-behavioral therapy for HD, and 30 of them participated in a 7-week CBT program.
Oxytocin, secreted by the pituitary gland, is known to play a role in sexual behavior, but has not been examined in HD men, the researchers said. At baseline, the mean plasma oxytocin was 31.0 pM in the HD patients, which was significantly higher than the mean 16.9 pM in healthy controls (P < .001). However, the 30 HD men who underwent CBT showed significant improvement in oxytocin levels, from a mean pretreatment level of 30.5 to a mean posttreatment level of 20.2 pM (P = .0000019).
The study findings were limited by several factors, including the lack of data on oxytocin for a wait list or control group, as well as the inability to control for confounding factors such as diet, physical activity, ethnicity, and stress, and a lack of data on sexual activity prior to oxytocin measurements, the researchers noted.
However, “although there is no clear consensus at this point, previous studies support the use of oxytocin plasma levels as a surrogate variable for [cerebrospinal fluid] oxytocin activity,” the researchers wrote in their discussion. The current study findings support the potential of oxytocin as a biomarker for HD diagnostics and also as a measure of disease severity. Larger studies to confirm the findings, especially those that exclude potential confounders, would be valuable.
Oxytocin may be treatment target
The study is important because of the lack of knowledge regarding the pathophysiology underlying hypersexual disorder, Dr. Chatzittofis of the University of Cyprus, Nicosia, said in an interview. “This is the first study to indicate a role for oxytocin’s involvement” in hypersexual disorder in men. Dr. Chatzittofis led a team in a previous study that showed an association between HD in men and dysregulation of the hypothalamic pituitary adrenal axis.
In the current study, “we discovered that men with compulsive sexual behavior disorder had higher oxytocin levels, compared with healthy men,” said Dr. Chatzittofis, adding that the take-home message for clinicians is the potential of CBT for treatment. “Cognitive-behavior therapy led to a reduction in both hypersexual behavior and oxytocin levels.” The results suggest that oxytocin plays an important role in sex addiction.
Consequently, oxytocin may be a potential drug target for future pharmacologic treatment of hypersexual disorder, he added.
The study was supported by the Swedish Research Council, the Stockholm County Council, and by a partnership between Umeå University and Västerbotten County Council. The researchers had no financial conflicts to disclose.
Men with hypersexual disorder showed higher levels of oxytocin in their blood than did healthy control men without the disorder, in a study with 102 participants.
Hypersexual disorder (HD) is characterized by “excessive and persistent sexual behaviors in relation to various mood states, with an impulsivity component and experienced loss of control,” John Flanagan, MD, of the Karolinska Institutet in Stockholm and colleagues wrote. Although HD is not included as a separate diagnosis in the current DSM, the similar disorder of compulsive sexual behavior is included in the ICD.
Data on the pathophysiology of HD are limited, although a previous study by corresponding author Andreas Chatzittofis, MD, and colleagues showed evidence of neuroendocrine dysregulation in men with HD, and prompted the current study to explore the possible involvement of the oxytocinergic system in HD.
In the current study, published in the Journal of Clinical Endocrinology & Metabolism, the researchers identified 64 men with HD and 38 healthy male controls. The patients were help-seeking men older than 18 years diagnosed with HD who presented to a single center in Sweden during 2013-2014. The men were included in a randomized clinical trial of cognitive-behavioral therapy for HD, and 30 of them participated in a 7-week CBT program.

Cancer, infection risk higher in transplant patients than rejection
“It’s important to have immunosuppression to protect people from rejection, but we wanted to be able to say, ‘What are the other causes of kidney failure that we might be able to identify that help improve longer-term outcomes’,” coauthor Andrew Bentall, MBChB, MD, a Mayo Clinic nephrologist, told this news organization.
“And I think the main thing we found is that we need to differentiate people into two groups,” he said, including younger, nondiabetic patients who develop graft failure due to alloimmunity and older often diabetic patients “who are less likely to have a rejection episode but who are still at high risk for death from a malignancy or infection so maybe we can modify their immunosuppression, for example, and reduce their mortality risk which could be very helpful.”
The study was published online Jan. 17 in Transplantation Direct.
Cohort study
The cohort was made up of 5,752 consecutive kidney transplant recipients treated at one of three Mayo Clinic sites. The mean age of recipients was 53.8 years and one-quarter were 65 years of age or older. “At the time of transplantation, 69.8% were on dialysis, and 10.3% had received a prior kidney,” of which half were from a deceased donor, the authors note.
Almost all patients received tacrolimus as part of their maintenance immunosuppressive regimen. At a median follow-up of 3.5 years, overall graft failure occurred in 21.6% of patients, including death with a functioning graft (DWFG) in 12% and graft failure in 9.6% of patients. The most common causes of DWFG included malignancy at 20.0%, followed closely by infection at 19.7%, investigators note.
Cardiac disease was the cause of DWFG in 12.6% of patients, and the cause was unknown in 37%. Of those patients who died with a functioning graft, 12.3% died within the first year of transplantation. Roughly 45% died between 1 and 5 years later, and 42% died more than 5 years after transplantation.
On multivariable analysis, independent predictors of DWFG included:
- Older age at transplantation (hazard ratio, 1.75; P < .001)
- Male sex (HR, 1.34; P < .001)
- Dialysis prior to transplant (HR, 1.49; P < .001)
- Diabetes as a cause of end-stage renal disease (ESRD) (HR, 1.88; P < .001)
- Prednisone use as maintenance therapy (HR, 1.34; P = .008)
Graft failure
Of patients who had graft failure, almost one-quarter occurred within the first year of transplantation, about 42% occurred 1 to 5 years later, and a third occurred more than 5 years later.
Most patients (39%) who went on to graft failure did so as a result of “alloimmunity”, a term investigators used to cover all types of rejection, with a smaller number of graft failures being caused by glomerular diseases, at 18.6%, and renal tubular injury, at 13.9%.
“In the first year after transplantation, surgical complications and primary nonfunction of the allograft caused 60.3% ... of graft losses,” the authors point out. Beyond the first year, alloimmunity accounted for approximately half of the cases of graft failure, investigators note.
In the multivariable analysis for overall graft failure, risk factors included:
- Young recipient age (HR, 0.80; P < .001)
- History of a previous kidney transplant (HR, 1.33; P = .042)
- Dialysis at time of transplantation (HR, 1.54; P < .001)
- Black recipient race (HR, 1.40; P = .006)
- Black donor race (HR, 1.35; P = .038)
- Diabetes as a cause of ESRD (HR, 1.40; P = .002)
- HLA mismatch (HR, 1.27; P < .001)
- Delayed graft function (HR, 2.20; P < .001)
“Over time, DWFG was more common than graft failure,” the authors note.
Modifiable risk factors
As Dr. Bentall acknowledged, not all risk factors contributing to DWFG or graft failure are modifiable. However, diabetes – which stood out as a risk factor for both DWFG and graft failure – is potentially modifiable before patients reach ESRD, as he suggested. Diabetes is currently a cause for up to 40% of all ESRD cases in the United States.
“We can’t necessarily always reverse the diabetes, but there are significant new medications that can be used along with weight loss strategies to improve diabetes control,” he noted.
Similarly, it’s well established that patients who come into transplantation with a body mass index in excess of 30 kg/m2 have more scarring and damage to the kidney 5- and 10-years post-transplantation than healthy weight patients, as Dr. Bentall observed. “Again, this is a key modifiable component, and it fits into diabetes intervention strategies as well,” he emphasized. The use of prednisone as maintenance immunosuppressive therapy similarly emerged as a risk factor for DWFG.
Transplant recipients who receive prednisone may well be a higher risk population to begin with, “but we are also using prednisone in our older patients because we try to use less induction immunosuppression at the time of transplantation. So if we can try and get people off prednisone, that may lessen their risk of infection and subsequent mortality,” Dr. Bentall noted.

FROM TRANSPLANTATION DIRECT
Vitamin D shows no survival benefit in nondeficient elderly
, including mortality linked to cardiovascular disease, new results from a large, placebo-controlled trial show.
“The take-home message is that routine vitamin D supplementation, irrespective of the dosing regimen, is unlikely to be beneficial in a population with a low prevalence of vitamin D deficiency,” first author Rachel E. Neale, PhD, of the Population Health Department, QIMR Berghofer Medical Research Institute, in Brisbane, Australia, told this news organization.
Despite extensive previous research on vitamin D supplementation, “mortality has not been the primary outcome in any previous large trial of high-dose vitamin D supplementation,” Dr. Neale and coauthors noted. The results, published online in Lancet Diabetes & Endocrinology, are from the D-Health trial.
With more than 20,000 participants, this is the largest intermittent-dosing trial to date, the authors noted. The primary outcome was all-cause mortality.
In an accompanying editorial, Inez Schoenmakers, PhD, noted that “the findings [are] highly relevant for population policy, owing to the study’s population-based design, large scale, and long duration.”
This new “research contributes to the concept that improving vitamin D status with supplementation in a mostly vitamin D-replete older population does not influence all-cause mortality,” Dr. Schoenmakers, of the Faculty of Medicine and Health Sciences, University of East Anglia, Norwich, England, said in an interview.
“This is not dissimilar to research with many other nutrients showing that increasing intake above the adequate intake has no further health benefits,” she added.
D-Health Trial
The D-Health Trial involved 21,315 participants in Australia, enrolled between February 2014 and June 2015, who had not been screened for vitamin D deficiency but were largely considered to be vitamin D replete. They were a mean age of 69.3 years and 54% were men.
Participants were randomized 1:1 to a once-monthly oral vitamin D3 supplementation of 60,000 IU (n = 10,662) or a placebo capsule (n = 10,653).
They were permitted to take up to 2,000 IU/day of supplemental vitamin D in addition to the study protocol and had no history of kidney stones, hypercalcemia, hyperparathyroidism, osteomalacia, or sarcoidosis.
Over a median follow-up of 5.7 years, there were 1,100 deaths: 562 in the vitamin D group (5.3%) and 538 in the placebo group (5.1%). With a hazard ratio (HR) for all-cause mortality of 1.04, the difference was not significant (P = .47).
There were also no significant differences in terms of mortality from cardiovascular disease (HR, 0.96; P = .77), cancer (HR, 1.15; P = .13), or other causes (HR, 0.83; P = .15).
Rates of total adverse events between the two groups, including hypercalcemia and kidney stones, were similar.
An exploratory analysis excluding the first 2 years of follow-up in fact showed a numerically higher hazard ratio for cancer mortality in the vitamin D group versus no supplementation (HR, 1.24; P = .05). However, the authors noted that the effect was “not apparent when the analysis was restricted to deaths that were coded by the study team and not officially coded.”
Nevertheless, “our findings, from a large study in an unscreened population, give pause to earlier reports that vitamin D supplements might reduce cancer mortality,” they underscored.
Retention and adherence in the study were high, each exceeding 80%. Although blood samples were not collected at baseline, samples from 3,943 randomly sampled participants during follow-up showed mean serum 25-hydroxy-vitamin D concentrations of 77 nmol/L in the placebo group and 115 nmol/L in the vitamin D group, both within the normal range of 50-125 nmol/L.
Findings supported by previous research
The trial results are consistent with those of prior large studies and meta-analyses of older adults with a low prevalence of vitamin D deficiency showing that vitamin D3 supplementation, regardless of whether taken daily or monthly, is not likely to have an effect on all-cause mortality.
In the US VITAL trial, recently published in the New England Journal of Medicine, among 25,871 participants administered 2,000 IU/day of vitamin D3 for a median of 5.3 years, there was no reduction in all-cause mortality.
The ViDA trial of 5,110 older adults in New Zealand, published in 2019 in the Journal of Endocrinological Investigation, also showed monthly vitamin D3 supplementation of 100,000 IU for a median of 3.3 years was not associated with a benefit in people who were not deficient.
“In total, the results from the large trials and meta-analyses suggest that routine supplementation of older adults in populations with a low prevalence of vitamin D deficiency is unlikely to reduce the rate of all-cause mortality,” Dr. Neale and colleagues concluded.
Longer-term supplementation beneficial?
The population was limited to older adults and the study had a relatively short follow-up period, which Dr. Neale noted was necessary for pragmatic reasons.
“Our primary outcome was all-cause mortality, so to have sufficient deaths we either needed to study older adults or a much larger sample of younger adults,” she explained.
“However, we felt that [the former] ... had biological justification, as there is evidence that vitamin D plays a role later in the course of a number of diseases, with potential impacts on mortality.”
She noted that recent studies evaluating genetically predicted concentrations of serum 25(OH)D have further shown no link between those levels and all-cause mortality, stroke, or coronary heart disease.
“This confirms the statement that vitamin D is unlikely to be beneficial in people who are not vitamin D deficient, irrespective of whether supplementation occurs over the short or longer term,” Dr. Neale said.
The source of vitamin D, itself, is another consideration, with ongoing speculation of differences in benefits between dietary or supplementation sources versus sunlight exposure.
“Exposure to ultraviolet radiation, for which serum 25(OH)D concentration is a good marker, might confer benefits not mediated by vitamin D,” Dr. Neale and coauthors noted.
They added that the results in the older Australian population “cannot be generalized to populations with a higher prevalence of vitamin D deficiency, or with a greater proportion of people not of White ancestry, than the study population.”
Ten-year mortality rates from the D-Health trial are expected to be reported in the future.
Strategies still needed to address vitamin D deficiency
Further commenting on the findings, Dr. Schoenmakers underscored that “vitamin D deficiency is very common worldwide, [and] more should be done to develop strategies to address the needs of those groups and populations that are at risk of the consequences of vitamin D deficiency.”
That said, the D-Health study is important in helping to distinguish when supplementation may – and may not – be of benefit, she noted.
“This and other research in the past 15 years have contributed to our understanding [of] what the ranges of vitamin D status are [in which] health consequences may be anticipated.”
The D-Health Trial was funded by the National Health and Medical Research Council. Dr. Neale and Dr. Schoenmakers have reported no relevant financial relationships.

With more than 20,000 participants, this is the largest intermittent-dosing trial to date, the authors noted. The primary outcome was all-cause mortality.
In an accompanying editorial, Inez Schoenmakers, PhD, noted that “the findings [are] highly relevant for population policy, owing to the study’s population-based design, large scale, and long duration.”
This new “research contributes to the concept that improving vitamin D status with supplementation in a mostly vitamin D-replete older population does not influence all-cause mortality,” Dr. Schoenmakers, of the Faculty of Medicine and Health Sciences, University of East Anglia, Norwich, England, said in an interview.
“This is not dissimilar to research with many other nutrients showing that increasing intake above the adequate intake has no further health benefits,” she added.
D-Health Trial
The D-Health Trial involved 21,315 participants in Australia, enrolled between February 2014 and June 2015, who had not been screened for vitamin D deficiency but were largely considered to be vitamin D replete. They were a mean age of 69.3 years and 54% were men.
Participants were randomized 1:1 to a once-monthly oral vitamin D3 supplementation of 60,000 IU (n = 10,662) or a placebo capsule (n = 10,653).
They were permitted to take up to 2,000 IU/day of supplemental vitamin D in addition to the study protocol and had no history of kidney stones, hypercalcemia, hyperparathyroidism, osteomalacia, or sarcoidosis.
Over a median follow-up of 5.7 years, there were 1,100 deaths: 562 in the vitamin D group (5.3%) and 538 in the placebo group (5.1%). With a hazard ratio (HR) for all-cause mortality of 1.04, the difference was not significant (P = .47).
There were also no significant differences in terms of mortality from cardiovascular disease (HR, 0.96; P = .77), cancer (HR, 1.15; P = .13), or other causes (HR, 0.83; P = .15).
Rates of total adverse events between the two groups, including hypercalcemia and kidney stones, were similar.
An exploratory analysis excluding the first 2 years of follow-up in fact showed a numerically higher hazard ratio for cancer mortality in the vitamin D group versus no supplementation (HR, 1.24; P = .05). However, the authors noted that the effect was “not apparent when the analysis was restricted to deaths that were coded by the study team and not officially coded.”
Nevertheless, “our findings, from a large study in an unscreened population, give pause to earlier reports that vitamin D supplements might reduce cancer mortality,” they underscored.
Retention and adherence in the study were high, each exceeding 80%. Although blood samples were not collected at baseline, samples from 3,943 randomly sampled participants during follow-up showed mean serum 25-hydroxy-vitamin D concentrations of 77 nmol/L in the placebo group and 115 nmol/L in the vitamin D group, both within the normal range of 50-125 nmol/L.
Findings supported by previous research
The trial results are consistent with those of prior large studies and meta-analyses of older adults with a low prevalence of vitamin D deficiency showing that vitamin D3 supplementation, regardless of whether taken daily or monthly, is not likely to have an effect on all-cause mortality.
In the US VITAL trial, recently published in the New England Journal of Medicine, among 25,871 participants administered 2,000 IU/day of vitamin D3 for a median of 5.3 years, there was no reduction in all-cause mortality.
The ViDA trial of 5,110 older adults in New Zealand, published in 2019 in the Journal of Endocrinological Investigation, also showed monthly vitamin D3 supplementation of 100,000 IU for a median of 3.3 years was not associated with a benefit in people who were not deficient.
“In total, the results from the large trials and meta-analyses suggest that routine supplementation of older adults in populations with a low prevalence of vitamin D deficiency is unlikely to reduce the rate of all-cause mortality,” Dr. Neale and colleagues concluded.
Longer-term supplementation beneficial?
The population was limited to older adults and the study had a relatively short follow-up period, which Dr. Neale noted was necessary for pragmatic reasons.
“Our primary outcome was all-cause mortality, so to have sufficient deaths we either needed to study older adults or a much larger sample of younger adults,” she explained.
“However, we felt that [the former] ... had biological justification, as there is evidence that vitamin D plays a role later in the course of a number of diseases, with potential impacts on mortality.”
She noted that recent studies evaluating genetically predicted concentrations of serum 25(OH)D have further shown no link between those levels and all-cause mortality, stroke, or coronary heart disease.
“This confirms the statement that vitamin D is unlikely to be beneficial in people who are not vitamin D deficient, irrespective of whether supplementation occurs over the short or longer term,” Dr. Neale said.
The source of vitamin D, itself, is another consideration, with ongoing speculation of differences in benefits between dietary or supplementation sources versus sunlight exposure.
“Exposure to ultraviolet radiation, for which serum 25(OH)D concentration is a good marker, might confer benefits not mediated by vitamin D,” Dr. Neale and coauthors noted.
They added that the results in the older Australian population “cannot be generalized to populations with a higher prevalence of vitamin D deficiency, or with a greater proportion of people not of White ancestry, than the study population.”
Ten-year mortality rates from the D-Health trial are expected to be reported in the future.
Strategies still needed to address vitamin D deficiency
Further commenting on the findings, Dr. Schoenmakers underscored that “vitamin D deficiency is very common worldwide, [and] more should be done to develop strategies to address the needs of those groups and populations that are at risk of the consequences of vitamin D deficiency.”
That said, the D-Health study is important in helping to distinguish when supplementation may – and may not – be of benefit, she noted.
“This and other research in the past 15 years have contributed to our understanding [of] what the ranges of vitamin D status are [in which] health consequences may be anticipated.”
The D-Health Trial was funded by the National Health and Medical Research Council. Dr. Neale and Dr. Schoenmakers have reported no relevant financial relationships.
