What’s the opposite of an antibiotic?

Everyone knows that LOTME loves a good dichotomy: yin/yang, good/evil, heads/tails, particle/wave, peanut butter/jelly. They’re all great. We’re also big fans of microbiomes, particularly the gut microbiome. But what if we could combine the two? A healthy and nutritious story about the gut microbiome, with a dash of added dichotomy for flavor. Is such a thing even possible? Let’s find out.

First, we need an antibiotic, a drug designed to fight bacterial infections. If you’ve got strep throat, otitis media, or bubonic plague, there’s a good chance you will receive an antibiotic. That antibiotic will kill the bad bacteria that are making you sick, but it will also kill a lot of the good bacteria that inhabit your gut microbiome, which results in side effects like bloating and diarrhea.

It comes down to diversity, explained Elisa Marroquin, PhD, of Texas Christian University (Go Horned Frogs!): “In a human community, we need people that have different professions because we don’t all know how to do every single job. And so the same happens with bacteria. We need lots of different gut bacteria that know how to do different things.”

She and her colleagues reviewed 29 studies published over the last 7 years and found a way to preserve the diversity of a human gut microbiome that’s dealing with an antibiotic. Their solution? Prescribe a probiotic.

The way to fight the effects of stopping a bacterial infection is to provide food for what are, basically, other bacterial infections. Antibiotic/probiotic is a prescription for dichotomy, and it means we managed to combine gut microbiomes with a dichotomy. And you didn’t think we could do it.
 

The earphone of hearing aids

It’s estimated that up to 75% of people who need hearing aids don’t wear them. Why? Well, there’s the social stigma about not wanting to appear too old, and then there’s the cost factor.

Is there a cheaper, less stigmatizing option to amplify hearing? The answer, according to otolaryngologist Yen-fu Cheng, MD, of Taipei Veterans General Hospital and associates, is wireless earphones. AirPods, if you want to be brand specific.

Airpods can be on the more expensive side – running about $129 for AirPods 2 and $249 for AirPods Pro – but when compared with premium hearing aids ($10,000), or even basic aids (about $1,500), the Apple products come off inexpensive after all.

The team tested the premium and basic hearing aids against the AirPods 2 and the AirPod Pro using Apple’s Live Listen feature, which helps amplify sound through the company’s wireless earphones and iPhones and was initially designed to assist people with normal hearing in situations such as birdwatching.

The AirPods Pro worked just as well as the basic hearing aid but not quite as well as the premium hearing aid in a quiet setting, while the AirPods 2 performed the worst. When tested in a noisy setting, the AirPods Pro was pretty comparable to the premium hearing aid, as long as the noise came from a lateral direction. Neither of the AirPod models did as well as the hearing aids with head-on noises.

Wireless earbuds may not be the perfect solution from a clinical standpoint, but they’re a good start for people who don’t have access to hearing aids, Dr. Cheng noted.

So who says headphones damage your hearing? They might actually help.
 

Now I lay me down to sleep, I pray the computer my soul to keep

Radiation is the boring hazard of space travel. No one dies in a space horror movie because they’ve been slowly exposed to too much cosmic radiation. It’s always “thrown out the airlock” this and “eaten by a xenomorph” that.

Radiation, however, is not something that can be ignored, but it turns out that a potential solution is another science fiction staple: artificial hibernation. Generally in sci-fi, hibernation is a plot convenience to get people from point A to point B in a ship that doesn’t break the laws of physics. Here on Earth, though, it is well known that animals naturally entering a state of torpor during hibernation gain significant resistance to radiation.

The problem, of course, is that humans don’t hibernate, and no matter how hard people who work 100-hour weeks for Elon Musk try, sleeping for months on end is simply something we can’t do. However, a new study shows that it’s possible to induce this torpor state in animals that don’t naturally hibernate. By injecting rats with adenosine 5’-monophosphate monohydrate and keeping them in a room held at 16° C, an international team of scientists successfully induced a synthetic torpor state.

That’s not all they did: The scientists also exposed the hibernating rats to a large dose of radiation approximating that found in deep space. Which isn’t something we’d like to explain to our significant other when we got home from work. “So how was your day?” “Oh, I irradiated a bunch of sleeping rats. … Don’t worry they’re fine!” Which they were. Thanks to the hypoxic and hypothermic state, the tissue was spared damage from the high-energy ion radiation.

Obviously, there’s a big difference between a rat and a human and a lot of work to be done, but the study does show that artificial hibernation is possible. Perhaps one day we’ll be able to fall asleep and wake up light-years away under an alien sky, and we won’t be horrifically mutated or riddled with cancer. If, however, you find yourself in hibernation on your way to Jupiter (or Saturn) to investigate a mysterious black monolith, we suggest sleeping with one eye open and gripping your pillow tight.

PHILADELPHIA – Hydroxychloroquine (HCQ) isn’t any more effective at preventing or delaying the onset of rheumatoid arthritis than placebo, based on interim results of a randomized clinical trial reported at the annual meeting of the American College of Rheumatology. Despite that futility, the percentage of patients who actually went on to develop clinical RA was lower than investigators expected, and the trial supports the use of a key biomarker for identifying RA.

While the StopRA trial was halted early because of futility of the treatment, investigators are continuing to mine the gathered data to deepen their understanding of disease progression and the potential of HCQ to improve symptoms in RA patients, said lead study author Kevin D. Deane, MD, PhD, of the University of Colorado at Denver, Aurora.

Richard Mark Kirkner/MDedge News

Overall, around 35% of the study participants on average developed RA, Dr. Deane said. “We were expecting somewhat more,” he said. “Teasing out who’s really going to progress to RA during a study and who’s not is going to be incredibly important.”

StopRA enrolled 144 adults who had elevated anti–cyclic citrullinated peptide antibodies (CCP3) levels of at least 40 units (about twice the normal level) but no history if inflammatory arthritis, randomizing them on a 1:1 basis to either HCQ (200-400 mg a day based on weight) or placebo for a 1-year treatment regimen.

The study identified participants through rheumatology clinics, testing of first-degree relatives with established RA, health fairs, blood donors, and biobanks. The interim findings are based on 2 years of follow-up after the last dose.

The study focused on HCQ because it has a relatively low risk profile with good safety and tolerability, is easy to administer, and is relatively low cost, Dr. Deane said.

StopRA study failed to meet its primary endpoint: to determine if 1 year of treatment with HCQ reduced the risk of developing inflammatory arthritis and classifiable RA at the end of 3 years in the study population. At the time of the interim analysis, 34% of patients in the HCQ arm and 36% in the placebo arm had developed RA (P = .844), Dr. Deane said. Baseline characteristics were balanced in both treatment arms.

The findings also support the use of CCP3 as a biomarker for RA, Dr. Deane said.

Now that the trial has been terminated, Dr. Deane said investigators are going to review the final data and perform secondary analyses for further clarity on the impact HCQ may have on RA.

“The future analysis should hopefully say if this treatment actually changes symptoms,” he said in an interview. “Because, if somebody felt better on the drug or had a milder form of rheumatoid arthritis once they developed it, that could potentially be a benefit.”

Dr. Deane noted the TREAT EARLIER trial similarly found that a 1-year course of methotrexate didn’t prevent the onset of clinical arthritis, but it did alter the disease course as measured in MRI-detected inflammation, related symptoms, and impairment.

“We’re hoping to look at those things and hopefully look at biologic changes over time,” Dr. Deane said of the extended analysis. “We’re not sure if the drug was associated with changes in biomarkers yet still didn’t halt progression to RA. That might be interesting, because those biomarkers might not be fundamentally related to the disease, but other mechanisms may be. That could give us some insights.”

Richard Mark Kirkner/MDedge News

Session moderator Ted Mikuls, MD, a professor of rheumatology at the University of Nebraska Medical Center, Omaha, said further mining of the study data is warranted.

“It’s common in a study like that, which took a lot of time and investment, to really take a deep dive into the data to make sure there aren’t signals that we’re missing,” he said in an interview.

One of the challenges with the study may have been patient enrollment, Dr. Mikuls noted. “I wonder about the study population in terms of where they recruit patients from. Who’s more likely to get RA? Is it patients who already have symptoms? Is it asymptomatic patients from biobanks? If it’s arthralgia joint pain patients, maybe by the time you have joint and autoantibody positivity it’s too late to have an intervention.”

The National Institute of Allergy and Infectious Diseases sponsored the study. Dr. Deane disclosed a relationship with Werfen. Dr. Mikuls has no relevant disclosures.

Roughly 7% of all adult Americans may currently have had long COVID, with symptoms that have lasted 3 months or longer, according to the latest U.S. government survey done in October. More than a quarter say their condition is severe enough to significantly limit their day-to-day activities – yet the problem is only barely starting to get the attention of employers, the health care system, and policymakers.

With no cure or treatment in sight, long COVID is already burdening not only the health care system, but also the economy – and that burden is set to grow. Many experts worry about the possible long-term ripple effects, from increased spending on medical care costs to lost wages due to not being able to work, as well as the policy implications that come with addressing these issues.

“At this point, anyone who’s looking at this seriously would say this is a huge deal,” says senior Brookings Institution fellow Katie Bach, the author of a study that analyzed long COVID’s impact on the labor market.

“We need a real concerted focus on treating these people, which means both research and the clinical side, and figuring out how to build a labor market that is more inclusive of people with disabilities,” she said.

It’s not only that many people are affected. It’s that they are often affected for months and possibly even years.

The U.S. government figures suggest more than 18 million people could have symptoms of long COVID right now. The latest Household Pulse Survey by the Census Bureau and the National Center for Health Statistics takes data from 41,415 people.

A preprint of a study by researchers from City University of New York, posted on medRxiv in September and based on a similar population survey done between June 30 and July 2, drew comparable results. The study has not been peer reviewed.

More than 7% of all those who answered said they had long COVID at the time of the survey, which the researchers said corresponded to approximately 18.5 million U.S. adults. The same study found that a quarter of those, or an estimated 4.7 million adults, said their daily activities were impacted “a lot.”

This can translate into pain not only for the patients, but for governments and employers, too.

In high-income countries around the world, government surveys and other studies are shedding light on the extent to which post-COVID-19 symptoms – commonly known as long COVID – are affecting populations. While results vary, they generally fall within similar ranges.

The World Health Organization estimates that between 10% and 20% of those with COVID-19 go on to have an array of medium- to long-term post-COVID-19 symptoms that range from mild to debilitating. The U.S. Government Accountability Office puts that estimate at 10% to 30%; one of the latest studies published at the end of October in The Journal of the American Medical Association found that 15% of U.S. adults who had tested positive for COVID-19 reported current long COVID symptoms. Elsewhere, a study from the Netherlands published in The Lancet in August found that one in eight COVID-19 cases, or 12.7%, were likely to become long COVID.

“It’s very clear that the condition is devastating people’s lives and livelihoods,” WHO Director-General Tedros Adhanom Ghebreyesus wrote in an article for The Guardian newspaper in October.

“The world has already lost a significant number of the workforce to illness, death, fatigue, unplanned retirement due to an increase in long-term disability, which not only impacts the health system, but is a hit to the overarching economy … the impact of long COVID for all countries is very serious and needs immediate and sustained action equivalent to its scale.”
 

Global snapshot: Lasting symptoms, impact on activities

Patients describe a spectrum of persistent issues, with extreme fatigue, brain fog or cognitive problems, and shortness of breath among the most common complaints. Many also have manageable symptoms that worsen significantly after even mild physical or mental exertion.

Women appear almost twice as likely as men to get long COVID. Many patients have other medical conditions and disabilities that make them more vulnerable to the condition. Those who face greater obstacles accessing health care due to discrimination or socioeconomic inequity are at higher risk as well. 

While many are older, a large number are also in their prime working age. The Census Bureau data show that people ages 40-49 are more likely than any other group to get long COVID, which has broader implications for labor markets and the global economy. Already, experts have estimated that long COVID is likely to cost the U.S. trillions of dollars and affect multiple industries.

“Whether they’re in the financial world, the medical system, lawyers, they’re telling me they’re sitting at the computer screen and they’re unable to process the data,” said Zachary Schwartz, MD, medical director for Vancouver General Hospital’s Post-COVID-19 Recovery Clinic.

“That is what’s most distressing for people, in that they’re not working, they’re not making money, and they don’t know when, or if, they’re going to get better.”

Nearly a third of respondents in the Census Bureau’s Household Pulse Survey who said they have had COVID-19 reported symptoms that lasted 3 months or longer. People between the ages of 30 and 59 were the most affected, with about 32% reporting symptoms. Across the entire adult U.S. population, the survey found that 1 in 7 adults have had long COVID at some point during the pandemic, with about 1 in 18 saying it limited their activity to some degree, and 1 in 50 saying they have faced “a lot” of limits on their activities. Any way these numbers are dissected, long COVID has impacted a large swath of the population.

Yet research into the causes and possible treatments of long COVID is just getting underway.

“The amount of energy and time devoted to it is way, way less than it should, given how many people are likely affected,” said David Cutler, PhD, professor of economics at Harvard University, Cambridge, Mass., who has written about the economic cost of long COVID. “We’re way, way underdoing it here. And I think that’s really a terrible thing.”

Population surveys and studies from around the world show that long COVID lives up to its name, with people reporting serious symptoms for months on end.

In October, Statistics Canada and the Public Health Agency of Canada published early results from a questionnaire done between spring and summer 2022 that found just under 15% of adults who had a confirmed or suspected case of COVID-19 went on to have new or continuing symptoms 3 or more months later. Nearly half, or 47.3%, dealt with symptoms that lasted a year or more. More than one in five said their symptoms “often or always” limited their day-to-day activities, which included routine tasks such as preparing meals, doing errands and chores, and basic functions such as personal care and moving around in their homes.

Nearly three-quarters of workers or students said they missed an average of 20 days of work or school. 

“We haven’t yet been able to determine exactly when symptoms resolve,” said Rainu Kaushal, MD, the senior associate dean for clinical research at Weill Cornell Medicine in New York. She is co-leading a national study on long COVID in adults and children, funded by the National Institutes of Health RECOVER Initiative.

“But there does seem to be, for many of the milder symptoms, resolution at about 4-6 weeks. There seems to be a second point of resolution around 6 months for certain symptoms, and then some symptoms do seem to be permanent, and those tend to be patients who have underlying conditions,” she said.
 

Reducing the risk

Given all the data so far, experts recommend urgent policy changes to help people with long COVID.

“The population needs to be prepared, that understanding long COVID is going to be a very long and difficult process,” said Alexander Charney, MD, PhD, associate professor and the lead principal investigator of the RECOVER adult cohort at Icahn School of Medicine at Mount Sinai in New York. He said the government can do a great deal to help, including setting up a network of connected clinics treating long COVID, standardizing best practices, and sharing information.

“That would go a long way towards making sure that every person feels like they’re not too far away from a clinic where they can get treated for this particular condition,” he said.

But the only known way to prevent long COVID is to prevent COVID-19 infections in the first place, experts say. That means equitable access to tests, therapeutics, and vaccines.

“I will say that avoiding COVID remains the best treatment in the arsenal right now,” said Dr. Kaushal. This means masking, avoiding crowded places with poor ventilation and high exposure risk, and being up to date on vaccinations, she said.

A number of papers – including a large U.K. study published in May 2022, another one from July, and the JAMA study from October – all suggest that vaccinations can help reduce the risk of long COVID.

“I am absolutely of the belief that vaccination has reduced the incidence and overall amount of long COVID … [and is] still by far the best thing the public can do,” said Dr. Schwartz.

Roughly 7% of all adult Americans may currently have had long COVID, with symptoms that have lasted 3 months or longer, according to the latest U.S. government survey done in October. More than a quarter say their condition is severe enough to significantly limit their day-to-day activities – yet the problem is only barely starting to get the attention of employers, the health care system, and policymakers.

With no cure or treatment in sight, long COVID is already burdening not only the health care system, but also the economy – and that burden is set to grow. Many experts worry about the possible long-term ripple effects, from increased spending on medical care costs to lost wages due to not being able to work, as well as the policy implications that come with addressing these issues.

“At this point, anyone who’s looking at this seriously would say this is a huge deal,” says senior Brookings Institution fellow Katie Bach, the author of a study that analyzed long COVID’s impact on the labor market.

“We need a real concerted focus on treating these people, which means both research and the clinical side, and figuring out how to build a labor market that is more inclusive of people with disabilities,” she said.

It’s not only that many people are affected. It’s that they are often affected for months and possibly even years.

The U.S. government figures suggest more than 18 million people could have symptoms of long COVID right now. The latest Household Pulse Survey by the Census Bureau and the National Center for Health Statistics takes data from 41,415 people.

A preprint of a study by researchers from City University of New York, posted on medRxiv in September and based on a similar population survey done between June 30 and July 2, drew comparable results. The study has not been peer reviewed.

More than 7% of all those who answered said they had long COVID at the time of the survey, which the researchers said corresponded to approximately 18.5 million U.S. adults. The same study found that a quarter of those, or an estimated 4.7 million adults, said their daily activities were impacted “a lot.”

This can translate into pain not only for the patients, but for governments and employers, too.

In high-income countries around the world, government surveys and other studies are shedding light on the extent to which post-COVID-19 symptoms – commonly known as long COVID – are affecting populations. While results vary, they generally fall within similar ranges.

The World Health Organization estimates that between 10% and 20% of those with COVID-19 go on to have an array of medium- to long-term post-COVID-19 symptoms that range from mild to debilitating. The U.S. Government Accountability Office puts that estimate at 10% to 30%; one of the latest studies published at the end of October in The Journal of the American Medical Association found that 15% of U.S. adults who had tested positive for COVID-19 reported current long COVID symptoms. Elsewhere, a study from the Netherlands published in The Lancet in August found that one in eight COVID-19 cases, or 12.7%, were likely to become long COVID.

“It’s very clear that the condition is devastating people’s lives and livelihoods,” WHO Director-General Tedros Adhanom Ghebreyesus wrote in an article for The Guardian newspaper in October.

“The world has already lost a significant number of the workforce to illness, death, fatigue, unplanned retirement due to an increase in long-term disability, which not only impacts the health system, but is a hit to the overarching economy … the impact of long COVID for all countries is very serious and needs immediate and sustained action equivalent to its scale.”
 

Global snapshot: Lasting symptoms, impact on activities

Patients describe a spectrum of persistent issues, with extreme fatigue, brain fog or cognitive problems, and shortness of breath among the most common complaints. Many also have manageable symptoms that worsen significantly after even mild physical or mental exertion.

Women appear almost twice as likely as men to get long COVID. Many patients have other medical conditions and disabilities that make them more vulnerable to the condition. Those who face greater obstacles accessing health care due to discrimination or socioeconomic inequity are at higher risk as well. 

While many are older, a large number are also in their prime working age. The Census Bureau data show that people ages 40-49 are more likely than any other group to get long COVID, which has broader implications for labor markets and the global economy. Already, experts have estimated that long COVID is likely to cost the U.S. trillions of dollars and affect multiple industries.

“Whether they’re in the financial world, the medical system, lawyers, they’re telling me they’re sitting at the computer screen and they’re unable to process the data,” said Zachary Schwartz, MD, medical director for Vancouver General Hospital’s Post-COVID-19 Recovery Clinic.

“That is what’s most distressing for people, in that they’re not working, they’re not making money, and they don’t know when, or if, they’re going to get better.”

PHILADELPHIA – For patients with rheumatoid arthritis who are already at increased risk for major adverse cardiovascular events (MACE), NSAIDs may be safer than opioids, results of a new-user active comparator study suggest.

Among 6,866 patients with RA who started on opioids and 13,698 patients who started on NSAIDs for pain, the use of both weak and strong opioids was associated with a 33% increase in risk for all-cause mortality and a trend toward higher rates of venous thromboembolism (VTE), compared with NSAID use, reported Gulsen Ozen, MD, of the University of Nebraska Medical Center, Omaha.

Neil Osterweil/MDedge News

“Pain in RA is a very complex process, and we know that it’s not solely dependent on the disease activity, but there is no evidence that opioids have any benefit in long-term pain management, and it can even cause hyperalgesia. And as we show, it’s not safer than NSAIDs,” she said in an oral abstract session at the annual meeting of the American College of Rheumatology.

She stressed that patients should be assessed for non-RA causes of pain and should use nonpharmacologic methods when possible.

“If a pharmacological treatment is needed and NSAIDs are contraindicated, the lowest possible dose of weak opioids can be used for a very limited time for acute pain only,” she said.
 

Pain despite disease control

Even when their disease is well controlled, approximately 60% of patients with RA still report pain. NSAIDs are commonly used to treat pain in patients with RA, but they are associated with modest increases in risk for cardiovascular disease (CVD), gastrointestinal bleeding, renal injury, and hypertension.

Some providers are leery of NSAIDs and will instead prescribe either regular or intermittent opioids for pain control in their patients.

Disease-modifying antirheumatic drugs have only minimal pain-relieving benefits, “and even worse, opioids can delay initiation of DMARDs in RA,” Dr. Ozen said.

Opioids have been shown to increase oxidative stress, platelet aggregation, and myocardial fibrosis, as well as hypogonadism, weight gain, and CVD risk factors.

There is little evidence, however, on whether opioids are associated with cardiovascular events in patients with RA. This dearth of data prompted Dr. Ozen and colleagues to study the relative risks for MACE in patients with RA starting on opioids or NSAIDs for pain.

Matched cohorts

They used data from FORWARD, a joint Canadian and U.S. databank for rheumatic diseases, to conduct a new-user active comparator cohort study. The cohort included adults with RA without cancer who participated in FORWARD for a minimum of 1 year between 1998 and 2021.

The patients were followed either from drug initiation until 3 months after the end of treatment, defined as either discontinuation or a switch to a different analgesic, end of study follow-up, or the development of a MACE outcome.

The investigators used propensity score matching to compare each opioid initiator with two NSAID initiators. The participants were matched by age, sex, body mass index, smoking, alcohol, RA duration, disease activity, Health Assessment Questionnaire, visual analog scale for pain, joint surgeries, prior CVD and VTE, hypertension, diabetes, rheumatic diseases comorbidity index, osteoporosis/fractures, thyroid, chronic liver, kidney, lung and mental health diseases, hospitalizations, 36-Item Short Form Health Survey scores, and sleep scores.

The two groups were well matched, except for a slightly higher incidence of VTE in opioid initiators, although incidence rates were low in both groups (0.9% vs. 0.6% of NSAID initiators).
 

Higher death rate in opioid users

The incidence rate of MACE among opioid initiators was 20.6% versus18.9% among NSAID initiators, a difference that was not statistically significant. There were also no significant differences in incidence rates of the individual components of the MACE composite outcome: myocardial infarction, stroke, heart failure, CVD death, or VTE.

There were, however, significantly more deaths from any cause among patients in the opioid group, with an incidence rate of 13.5% versus 10.8% in the NSAID group.

An analysis of the associaion of drug type with outcomes, adjusted for propensity score weight and prior VTE showed that patients on opioids had a statistically significant hazard ratio for death from any cause of 1.33 (95% confidence interval, 1.06-1.67).

The increased risk for all-cause mortality occurred both in patients starting on weak opioids (hydrocodone, tramadol, codeine, pentazocine, and propoxyphene) and on strong opioids (hydromorphone, dihydromorphinone, oxymorphone, butorphanol, methadone, morphine, oxycodone, meperidine, and fentanyl).

As noted before, there was a trend toward an increased risk for VTE among opioid initiators, but this was not statistically significant.

The increase in risk was higher among patients on strong versus weak opioids, suggesting a dose-dependent relationship, Dr. Ozen said.

A comparison of opioid-associated risk for all-cause mortality vs. NSAIDs according to type (nonselective or selective) showed that most of the increase in risk was relative to selective cycloxygenase-2 inhibitors.

‘Beautiful’ analysis

“This is a beautiful piece of analysis on a really difficult question to address because the confounding is really hard to unpick,” commented James Galloway, MBBS, deputy head of the center for rheumatic diseases at King’s College London and consulting rheumatologist at King’s College Hospital, also in London.

“The headline message is that there didn’t appear to be a clear signal that NSAIDs were worse, which is what I thought the preexisting view might have been. And so, people may have paradoxically prescribed opioids in favor of NSAIDs in a person with cardiovascular risk,” he said in an interview. Dr. Galloway attended the oral abstract session but was not involved in the study.

The study was supported by a grant to Dr. Ozen from the Rheumatology Research Foundation. Dr. Galloway reported having no relevant disclosures.

And as we show, it’s not safer than NSAIDs,” she said in an oral abstract session at the annual meeting of the American College of Rheumatology.

She stressed that patients should be assessed for non-RA causes of pain and should use nonpharmacologic methods when possible.

“If a pharmacological treatment is needed and NSAIDs are contraindicated, the lowest possible dose of weak opioids can be used for a very limited time for acute pain only,” she said.
 

Pain despite disease control

Even when their disease is well controlled, approximately 60% of patients with RA still report pain. NSAIDs are commonly used to treat pain in patients with RA, but they are associated with modest increases in risk for cardiovascular disease (CVD), gastrointestinal bleeding, renal injury, and hypertension.

Some providers are leery of NSAIDs and will instead prescribe either regular or intermittent opioids for pain control in their patients.

Disease-modifying antirheumatic drugs have only minimal pain-relieving benefits, “and even worse, opioids can delay initiation of DMARDs in RA,” Dr. Ozen said.

Opioids have been shown to increase oxidative stress, platelet aggregation, and myocardial fibrosis, as well as hypogonadism, weight gain, and CVD risk factors.

There is little evidence, however, on whether opioids are associated with cardiovascular events in patients with RA. This dearth of data prompted Dr. Ozen and colleagues to study the relative risks for MACE in patients with RA starting on opioids or NSAIDs for pain.

Matched cohorts

They used data from FORWARD, a joint Canadian and U.S. databank for rheumatic diseases, to conduct a new-user active comparator cohort study. The cohort included adults with RA without cancer who participated in FORWARD for a minimum of 1 year between 1998 and 2021.

The patients were followed either from drug initiation until 3 months after the end of treatment, defined as either discontinuation or a switch to a different analgesic, end of study follow-up, or the development of a MACE outcome.

The investigators used propensity score matching to compare each opioid initiator with two NSAID initiators. The participants were matched by age, sex, body mass index, smoking, alcohol, RA duration, disease activity, Health Assessment Questionnaire, visual analog scale for pain, joint surgeries, prior CVD and VTE, hypertension, diabetes, rheumatic diseases comorbidity index, osteoporosis/fractures, thyroid, chronic liver, kidney, lung and mental health diseases, hospitalizations, 36-Item Short Form Health Survey scores, and sleep scores.

The two groups were well matched, except for a slightly higher incidence of VTE in opioid initiators, although incidence rates were low in both groups (0.9% vs. 0.6% of NSAID initiators).
 

Higher death rate in opioid users

The incidence rate of MACE among opioid initiators was 20.6% versus18.9% among NSAID initiators, a difference that was not statistically significant. There were also no significant differences in incidence rates of the individual components of the MACE composite outcome: myocardial infarction, stroke, heart failure, CVD death, or VTE.

There were, however, significantly more deaths from any cause among patients in the opioid group, with an incidence rate of 13.5% versus 10.8% in the NSAID group.

An analysis of the associaion of drug type with outcomes, adjusted for propensity score weight and prior VTE showed that patients on opioids had a statistically significant hazard ratio for death from any cause of 1.33 (95% confidence interval, 1.06-1.67).

The increased risk for all-cause mortality occurred both in patients starting on weak opioids (hydrocodone, tramadol, codeine, pentazocine, and propoxyphene) and on strong opioids (hydromorphone, dihydromorphinone, oxymorphone, butorphanol, methadone, morphine, oxycodone, meperidine, and fentanyl).

As noted before, there was a trend toward an increased risk for VTE among opioid initiators, but this was not statistically significant.

The increase in risk was higher among patients on strong versus weak opioids, suggesting a dose-dependent relationship, Dr. Ozen said.

A comparison of opioid-associated risk for all-cause mortality vs. NSAIDs according to type (nonselective or selective) showed that most of the increase in risk was relative to selective cycloxygenase-2 inhibitors.

‘Beautiful’ analysis

“This is a beautiful piece of analysis on a really difficult question to address because the confounding is really hard to unpick,” commented James Galloway, MBBS, deputy head of the center for rheumatic diseases at King’s College London and consulting rheumatologist at King’s College Hospital, also in London.

“The headline message is that there didn’t appear to be a clear signal that NSAIDs were worse, which is what I thought the preexisting view might have been. And so, people may have paradoxically prescribed opioids in favor of NSAIDs in a person with cardiovascular risk,” he said in an interview. Dr. Galloway attended the oral abstract session but was not involved in the study.

The study was supported by a grant to Dr. Ozen from the Rheumatology Research Foundation. Dr. Galloway reported having no relevant disclosures.

Boston dietitian Katarina Mollo, MEd, RDN, LDN, has virtually no memory of life without celiac disease (CD). Diagnosed at age 4, Dr. Mollo has been on a gluten-free diet for 41 years, which she says has kept her healthy and may also be why she hasn’t developed other autoimmune diseases. It’s also played a part in her thinking about screening patients with CD.

“I think [physicians] should definitely be screening people with celiac disease for autoimmune disorders, especially if they see things like anemia or if a child has dropped on the growth chart and has nutrient deficiencies,” said Dr. Mollo, whose daughter also has the disease. “I would recommend that they see someone who specializes in celiac disease so they can get monitored and have regular follow-up checks for nutrient deficiencies and other autoimmune disorders.”

Dr. Mollo’s views on screening are echoed by many CD specialists and physicians, who cite multiple studies that have found that people with the disease face higher risks for diabetes, thyroid conditions, arthritis, and other autoimmune disorders.

Gastroenterologist Alessio Fasano, MD, with Massachusetts General Hospital, Boston, said there has been a “shift in the paradigm in thinking” about cross-screening for CD and autoimmune disorders. As result, he believes the answer to the question of whether to routinely do so is a no-brainer.

“The bottom line is, if you have CD, it [should be] routine that during your annual follow-ups you check for the possibility of the onset of other autoimmune disease. And people with other autoimmune diseases, like type 1 diabetes, should also be screened for CD because of the comorbidity,” said Dr. Fasano, professor of pediatrics and gastroenterology at Harvard Medical School and professor of nutrition at the Harvard School of Public Health, both in Boston. “This is what we call good clinical practice.”
 

Screening, despite lack of consensus guidelines

Other CD specialists differ on the need for universal cross-screening but agree that, at least in some cases, people with one autoimmune disorder should be tested for others.

Jolanda Denham, MD, a pediatric gastroenterologist affiliated with Nemours Children’s Hospital in Orlando, routinely recommends that her patients with CD be screened for certain autoimmune disorders – such as type 1 diabetes and autoimmune thyroid and liver diseases – even though medical organizations have not developed clear consensus or standard guidelines on cross-screening.

“There currently is no evidence to support the screening of celiac patients for all autoimmune and rheumatologic disorders,” she said. “It is true that celiac disease is an autoimmune disorder, and as such, there is a definite increased risk of these disorders in patients with celiac disease and vice versa.”

Echoing Dr. Denham, New York–based gastroenterologist Benjamin Lebwohl, MD, president of the Society for the Study of Celiac Disease, urges physicians to look beyond consensus guidelines and to err on the side of caution and make the best decisions for their patients on a case-by-case basis.

“Given the increased risk of certain autoimmune conditions in people with celiac disease, it behooves physicians to have a low threshold to evaluate for these conditions if any suggestive symptoms are present,” said Dr. Lebwohl, director of clinical research at the Celiac Disease Center at Columbia University, New York.

“Whether to screen for these conditions among people who are entirely without symptoms is less certain, and there is no consensus on that. But it is reasonable and common to include some basic tests with annual blood work, such as thyroid function and a liver profile, since both autoimmune thyroid disease and autoimmune liver disease can be silent early on and the patient would potentially benefit from identification and treatment of these conditions,” he said.

The American Diabetes Association and the International Society of Pediatric and Adolescent Diabetes do recommend that people with diabetes be screened for CD years after diagnosis, noted Robert Rapaport, MD, a pediatric endocrinologist, with Kravis Children’s Hospital, New York. But in a study published in 2021, he and colleagues found that this wasn’t occurring, which prompted them to recommend yearly screening.

“There is a consensus that in children with type 1 diabetes, we screen them for other autoimmune disorders, specifically for thyroid disease and celiac disease,” said Dr. Rapaport, who is also Emma Elizabeth Sullivan Professor of Pediatric Endocrinology and Diabetes at Icahn School of Medicine at Mount Sinai, New York. “But there is no consensus going the other way – for patients with celiac disease, what other autoimmune conditions they should be screened for.”

This hasn’t kept some doctors from extending cross-screening efforts to their patients.

“At our center, we screen ... for thyroid disease and autoimmune liver disease as part of routine healthcare maintenance for our celiac disease patients. We discuss symptoms of diabetes and send screening with [hemoglobin] A1c for anyone who has symptoms,” said Lui Edwin, MD, a pediatric gastroenterologist with Children’s Hospital Colorado, Aurora, and director of the Colorado Center for Celiac Disease, who delivered a lecture on CD-autoimmune screening at the International Celiac Disease Symposium in October.

“It is definitely worth screening for celiac disease in [those with] other autoimmune disorders,” Dr. Edwin added.

“The symptoms can be very heterogeneous. Diagnosing and treating celiac disease can make a huge impact with respect to symptoms, quality of life, and preventing disease-related complications,” he said.
 

Mounting evidence linking CD to autoimmune disorders

Many studies have linked CD to a variety of other autoimmune disorders. The association could be due to common genetic factors or because CD might lead to such conditions. Researchers have found that people diagnosed with CD later in life are more likely to develop other autoimmune disorders.

Going gluten free has preventive advantages

In a landmark 2012 study, researchers with the Celiac Disease Center at Columbia University stopped short of recommending routine screening for the general public or asymptomatic individuals in high-prevalence groups. But they concluded that more screening of symptomatic individuals – and close relatives – would speed treatment for those with more than one autoimmune disorder.

They also noted that some studies have found that a gluten-free diet might help prevent the development of other autoimmune disorders.

Marisa Gallant Stahl, MD, a gastroenterologist with Children’s Hospital Colorado, agreed that it is important that physicians keep gluten-free diets in mind when determining which patients to cross-screen.

“The literature is mixed, but some studies suggest that treating celiac disease with a gluten-free diet actually augments the treatment and control of other autoimmune disorders [and] adherence to a gluten-free diet does reduce the risk of cancer associated with celiac disease,” she said.

Dr. Denham agreed. “Strict adherence to a gluten-free diet definitely protects against the development of enteropathy-associated T-cell lymphoma but may be protective against non-Hodgkin’s lymphoma and adenocarcinoma of the small intestine as well. All three are associated with long-term nonadherence to a gluten-free diet.”

She also noted that a gluten-free diet may help people with CD manage other autoimmune disorders, which can be complicated by CD.

“Good control of celiac disease will help prevent complications that can worsen symptoms and outcomes of concomitant autoimmune and rheumatologic disorders,” she said.
 

Other factors to consider

Dr. Fasano added that autoimmune disorders can be complicated by CD in cases in which oral medications or healthful foods are not properly absorbed in the intestines.

“For example, with Hashimoto’s disease, if you have hormone replacement with oral treatments and your intestines are not 100% functional because you have inflammation, then you may have a problem [with] the absorption of medications like levothyroxine,” he said.

“It’s the same story with diabetes. You don’t take insulin by mouth, but glucose [control] strongly depends on several factors, mostly what comes from the diet, and if it’s erratic, that can be a problem. ... So, the treatment of autoimmune diseases can be influenced by celiac disease,” he said.

In addition, Dr. Fasano and others believe that people with CD and other autoimmune disorders should be managed by a team of experts who can personalize the care on the basis of specific needs of the individual patient. These should include specialists, dietitians, mental health counselors, and family social workers.

“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

In most cases, passengers on an airline flight are representative of the general population, which means that anyone could have an emergency at any time.

A study published in the New England Journal of Medicine in 2013 showed that a medical emergency occurred in 1 per 604 flights, as determined on the basis of in-flight medical emergencies that resulted in calls to a physician-directed medical communications center, said Amy Faith Ho, MD, MPH of Integrative Emergency Services, Dallas–Fort Worth, in a presentation at the annual meeting of the American College of Emergency Physicians.

The study authors reviewed records of 11,920 in-flight medical emergencies between Jan. 1, 2008, and Oct. 31, 2010. The data showed that physician passengers provided medical assistance in nearly half of in-flight emergencies (48.1%) and that flights were diverted because of the emergency in 7.3% of cases.

The majority of the in-flight emergencies involved syncope or presyncope (37.4% of cases), followed by respiratory symptoms (12.1%) and nausea or vomiting (9.5%), according to the study.

The in-flight medical bag

Tools in a physician’s in-flight toolbox start with the first-aid kit. Airplanes also have an emergency medical kit (EMK), an oxygen tank, and an AED.

The minimum EMK contents are mandated by the Federal Aviation Administration, said Dr. Ho. The standard equipment includes a stethoscope, a sphygmomanometer, and three sizes of oropharyngeal airways. Other items include self-inflating manual resuscitation devices and CPR masks in thee sizes, alcohol sponges, gloves, adhesive tape, scissors, a tourniquet, as well as saline solution, needles, syringes, and an intravenous administration set consisting of tubing and two Y connectors.

An EMK also should contain the following medications: nonnarcotic analgesic tablets, antihistamine tablets, an injectable antihistamine, atropine, aspirin tablets, a bronchodilator, and epinephrine (both 1:1000; 1 injectable cc and 1:10,000; two injectable cc). Nitroglycerin tablets and 5 cc of 20 mg/mL injectable cardiac lidocaine are part of the mandated kit as well, according to Dr. Ho.

Some airlines carry additional supplies on all their flights, said Dr. Ho. Notably, American Airlines and British Airways carry EpiPens for adults and children, as well as opioid reversal medication (naloxone) and glucose for managing low blood sugar. American Airlines and Delta stock antiemetics, and Delta also carries naloxone. British Airways is unique in stocking additional cardiac medications, both oral and injectable.
 

How to handle an in-flight emergency

Physicians should always carry a copy of their medical license when traveling for documentation by the airline if they assist in a medical emergency during a flight, Dr. Ho emphasized. “Staff” personnel should be used. These include the flight attendants, medical ground control, and other passengers who might have useful skills, such as nursing, the ability to perform CPR, or therapy/counseling to calm a frightened patient. If needed, “crowdsource additional supplies from passengers,” such as a glucometer or pulse oximeter.

Legal lessons

Physicians are not obligated to assist during an in-flight medical emergency, said Dr. Ho. Legal jurisdiction can vary. In the United States, a bystander who assists in an emergency is generally protected by Good Samaritan laws; for international airlines, the laws may vary; those where the airline is based usually apply.

The Aviation Medical Assistance Act, passed in 1998, protects individuals from being sued for negligence while providing medical assistance, “unless the individual, while rendering such assistance, is guilty of gross negligence of willful misconduct,” Dr. Ho noted. The Aviation Medical Assistance Act also protects the airline itself “if the carrier in good faith believes that the passenger is a medically qualified individual.”

Dr. Ho disclosed no relevant financial relationships.

The majority of the in-flight emergencies involved syncope or presyncope (37.4% of cases), followed by respiratory symptoms (12.1%) and nausea or vomiting (9.5%), according to the study.

The in-flight medical bag

Tools in a physician’s in-flight toolbox start with the first-aid kit. Airplanes also have an emergency medical kit (EMK), an oxygen tank, and an AED.

The minimum EMK contents are mandated by the Federal Aviation Administration, said Dr. Ho. The standard equipment includes a stethoscope, a sphygmomanometer, and three sizes of oropharyngeal airways. Other items include self-inflating manual resuscitation devices and CPR masks in thee sizes, alcohol sponges, gloves, adhesive tape, scissors, a tourniquet, as well as saline solution, needles, syringes, and an intravenous administration set consisting of tubing and two Y connectors.

An EMK also should contain the following medications: nonnarcotic analgesic tablets, antihistamine tablets, an injectable antihistamine, atropine, aspirin tablets, a bronchodilator, and epinephrine (both 1:1000; 1 injectable cc and 1:10,000; two injectable cc). Nitroglycerin tablets and 5 cc of 20 mg/mL injectable cardiac lidocaine are part of the mandated kit as well, according to Dr. Ho.

Some airlines carry additional supplies on all their flights, said Dr. Ho. Notably, American Airlines and British Airways carry EpiPens for adults and children, as well as opioid reversal medication (naloxone) and glucose for managing low blood sugar. American Airlines and Delta stock antiemetics, and Delta also carries naloxone. British Airways is unique in stocking additional cardiac medications, both oral and injectable.
 

How to handle an in-flight emergency

Physicians should always carry a copy of their medical license when traveling for documentation by the airline if they assist in a medical emergency during a flight, Dr. Ho emphasized. “Staff” personnel should be used. These include the flight attendants, medical ground control, and other passengers who might have useful skills, such as nursing, the ability to perform CPR, or therapy/counseling to calm a frightened patient. If needed, “crowdsource additional supplies from passengers,” such as a glucometer or pulse oximeter.

Legal lessons

Physicians are not obligated to assist during an in-flight medical emergency, said Dr. Ho. Legal jurisdiction can vary. In the United States, a bystander who assists in an emergency is generally protected by Good Samaritan laws; for international airlines, the laws may vary; those where the airline is based usually apply.

The Aviation Medical Assistance Act, passed in 1998, protects individuals from being sued for negligence while providing medical assistance, “unless the individual, while rendering such assistance, is guilty of gross negligence of willful misconduct,” Dr. Ho noted. The Aviation Medical Assistance Act also protects the airline itself “if the carrier in good faith believes that the passenger is a medically qualified individual.”

Dr. Ho disclosed no relevant financial relationships.

In most cases, passengers on an airline flight are representative of the general population, which means that anyone could have an emergency at any time.

A study published in the New England Journal of Medicine in 2013 showed that a medical emergency occurred in 1 per 604 flights, as determined on the basis of in-flight medical emergencies that resulted in calls to a physician-directed medical communications center, said Amy Faith Ho, MD, MPH of Integrative Emergency Services, Dallas–Fort Worth, in a presentation at the annual meeting of the American College of Emergency Physicians.

ORLANDO – Hospitalization rates were higher in patients with advanced chronic kidney disease (CKD) treated with dialysis than those treated with conservative management, among those with an estimated glomerular filtration rate (eGFR) less than 25 mL/min/1.73m² and in most racial/ethnic groups, new research shows.

“Patients mostly start dialysis because of unpleasant symptoms that cause suffering, including high potassium levels and high levels of uremic toxins in the blood,” senior author Kamyar Kalantar-Zadeh, MD, PhD, MPH, told this news organization.

“Conservative management serves to address and manage these symptoms and levels of toxicities without dialysis, so conservative management is an alternative approach, and patients should always be given a choice between [the two],” stressed Dr. Kalantar-Zadeh, professor of medicine at the University of California, Irvine.

The results were presented during the annual meeting of the American Society of Nephrology.

“There has been growing recognition of the importance of conservative nondialytic management as an alternative patient-centered treatment strategy for advanced kidney disease. However, conservative management remains under-utilized in the United States, which may in part be due to uncertainties regarding which patients will most benefit from dialysis versus nondialytic treatment,” said first author Connie Rhee, MD, also of the University of California, Irvine.

“We hope that these findings and further research can help inform treatment options for patients, care partners, and providers in the shared decision-making process of conservative management versus dialysis,” added Dr. Rhee, in a press release from the American Society of Nephrology.

Asked for comment, Sarah Davison, MD, noted that part of the Society’s strategy is, in fact, to promote conservative kidney management (CKM) as a key component of integrated care for patients with kidney failure. Dr. Davison is professor of medicine and chair of the International Society Working Group for Kidney Supportive Care and Conservative Kidney Management.

“We’ve recognized for a long time that there are many patients for whom dialysis provides neither a survival advantage nor a quality of life advantage,” she told this news organization.

“These patients tend to be those who have multiple morbidities, who are more frail, and who tend to be older, and in fact, the patients can live as long, if not longer, with better symptom management and better quality of life by not being on dialysis,” she stressed.
 

Study details

In the study, using data from the Optum Labs Data Warehouse, patients with advanced CKD were categorized according to whether or not they received conservative management, defined as those who did not receive dialysis within 2 years of the index eGFR (first eGFR < 25 mL/min/1.73m²) versus receipt of dialysis parsed as late versus early dialysis transition (eGFR < 15 vs. ≥ 15 mL/min/1.73m² at dialysis initiation).

Hospitalization rates were compared between those treated with conservative management, compared with late or early dialysis.

“Among 309,188 advanced CKD patients who met eligibility [criteria], 55% of patients had greater than or equal to 1 hospitalization(s) within 2 years of the index eGFR,” the authors report. The most common causes of hospitalization among all patients were congestive heart failure, respiratory symptoms, or hypertension.

In most racial groups (non-Hispanic White, non-Hispanic Black, and Hispanic patients), patients on dialysis had higher hospitalization rates than those who received conservative management, and patients who started dialysis early (transitioned to dialysis at higher levels of kidney function) demonstrated the highest rates across all age groups, compared with those who started dialysis late (transitioned to dialysis at lower levels of kidney function) or were treated with conservative management.

Among Asian patients, those on dialysis also had higher hospitalization rates than those receiving conservative management, but patients who started dialysis late had higher rates than those on early dialysis, especially in older age groups, possibly because they were sicker, Dr. Kalantar-Zadeh suggested.
 

Conservative care has pros and cons, but Canada has embraced it

As Dr. Kalantar-Zadeh explained, conservative management has its pros and cons, compared with dialysis. “Conservative management requires that patients work with the multidisciplinary team including nephrologists, nutritionists, and others to try to manage CKD without dialysis, so it requires patient participation.”

On the other hand, dialysis is both easier and more lucrative than conservative management, at least for nephrologists, as they are well-trained in dialysis care, and it can be systematically applied. As to which patients with CKD might be optimal candidates for conservative management, Dr. Kalantar-Zadeh agreed this requires further study.

But he acknowledged that most nephrologists are not hugely supportive of conservative management because they are less well-trained in it, and it is more time-consuming. The one promising change is a new model introduced in 2022, a value-based kidney care model, that, if implemented, will be more incentivizing for nephrologists to offer conservative care more widely.

Dr. Davison meanwhile believes the “vast majority” of nephrologists based in Canada – as she is – are “highly supportive” of CKM as an important modality.

“The challenge, however, is that many nephrologists remain unsure as to how to best deliver or optimize all aspects of CKM, whether that is symptom management, advanced care planning, or how they must manage symptoms to align with a patient’s goals,” Dr. Davison explained.

“But it’s not that they do not believe in the value of CKM.”

Indeed, in her province, Alberta, nephrologists have been offering CKM for decades, and while they are currently standardizing care to make it easier to deliver, there is no financial incentive to offer dialysis over CKM.

“We are now seeing those elements of kidney supportive care as part of core competencies to manage any person with chronic illness, including CKD,” Dr. Davison said.

“So it’s absolutely doable, and contrary to one of the myths about CKM, it is not more time-consuming than dialysis – not when you know how to do it. You are just shifting your focus,” she emphasized.

The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Kalantar-Zadeh has reported receiving honoraria and medical directorship fees from Fresenius and DaVita. Dr. Davison has reported no relevant financial relationships.

PHILADELPHIA – Prednisone appears to have the edge over colchicine for control of pain in patients with acute calcium pyrophosphate (CPP) crystal arthritis, an intensely painful rheumatic disease primarily affecting older patients.

Among 111 patients with acute CPP crystal arthritis randomized to receive either prednisone or colchicine for control of acute pain in a multicenter study, 2 days of therapy with the oral agents provided equivalent pain relief on the second day, and patients generally tolerated each agent well, reported Tristan Pascart, MD, from the Groupement Hospitalier de l’Institut Catholique de Lille (France).

Neil Osterweil/MDedge News

“Almost three-fourths of patients are considered to be good responders to both drugs on day 3, and, maybe, safety is the key issue distinguishing the two treatments: Colchicine was generally well tolerated, but even with this very short time frame of treatment, one patient out of five had diarrhea, which is more of a concern in this elderly population at risk of dehydration,” he said in an oral abstract session at the annual meeting of the American College of Rheumatology.

In contrast, only about 6% of patients assigned to prednisone had diarrhea, and other adverse events that occurred more frequently with the corticosteroid, including hypertension, hyperglycemia, and insomnia all resolved after the therapy was stopped.
 

Common and acutely painful

Acute CPP crystal arthritis is a common complication that often occurs during hospitalization for primarily nonrheumatologic causes, Dr. Pascart said, and “in the absence of clinical trials, the management relies on expert opinion, which stems from extrapolated data from gap studies” primarily with prednisone or colchicine, Dr. Pascart said.

To fill in the knowledge gap, Dr. Pascart and colleagues conducted the COLCHICORT study to evaluate whether the two drugs were comparable in efficacy and safety for control of acute pain in a vulnerable population.

The multicenter, open-label trial included patients older than age 65 years with an estimated glomerular filtration rate above 30 mL/min per 1.73 m² who presented with acute CPP deposition arthritis with symptoms occurring within the previous 36 hours. CPP arthritis was defined by the identification of CPP crystals on synovial fluid analysis or typical clinical presentation with evidence of chondrocalcinosis on x-rays or ultrasound.

Patients with a history of gout, cognitive decline that could impair pain assessment, or contraindications to either of the study drugs were excluded.

The participants were randomized to receive either colchicine 1.5 mg (1 mg to start, then 0.5 mg one hour later) at baseline and then 1 mg on day 1, or oral prednisone 30 mg at baseline and on day 1. The patients also received 1 g of systemic acetaminophen, and three 50-mg doses of tramadol during the first 24 hours.

Of the 111 patients randomized, 54 were assigned to receive prednisone, and 57 were assigned to receive colchicine. Baseline characteristics were similar between the groups, with a mean age of about 86 years, body mass index of around 25 kg/m², and blood pressure in the range of 130/69 mm Hg.

For nearly half of all patients in study each arm the most painful joint was the knee, followed by wrists and ankles.

There was no difference between the groups in the primary efficacy outcome of a change at 24 hours over baseline in visual analog scale (VAS) (0-100 mm) scores, either in a per-protocol analysis or modified intention-to-treat analysis. The mean change in VAS at 24 hours in the colchicine group was –36.6 mm, compared with –37.7 mm in the prednisone group. The investigators had previously determined that any difference between the two drugs of less than 13 mm on pain VAS at 24 hours would meet the definition for equivalent efficacy.

In both groups, a majority of patients had either an improvement greater than 50% in pain VAS scores and/or a pain VAS score less than 40 mm at both 24 and 48 hours.

At 7 days of follow-up, 21.8% of patients assigned to colchicine had diarrhea, compared with 5.6% of those assigned to prednisone. Adverse events occurring more frequently with prednisone included hyperglycemia, hypertension, and insomnia.

Patients who received colchicine and were also on statins had a trend toward a higher risk for diarrhea, but the study was not adequately powered to detect an association, and the trend was not statistically significant, Dr. Pascart said.

“Taken together, safety issues suggest that prednisone should be considered as the first-line therapy in acute CPP crystal arthritis. Future research is warranted to determine factors increasing the risk of colchicine-induced diarrhea,” he concluded.
 

Both drugs are used

Sara K. Tedeschi, MD, from Brigham & Women’s Hospital in Boston, who attended the session where the data were presented, has a special clinical interest in CPP deposition disease. She applauded Dr. Pascart and colleagues for conducting a rare clinical trial in CPP crystal arthritis.

In an interview, she said that the study suggests “we can keep in mind shorter courses of treatment for acute CPP crystal arthritis; I think that’s one big takeaway from this study.”

Asked whether she would change her practice based on the findings, Dr. Tedeschi replied: “I personally am not sure that I would be moved to use prednisone more than colchicine; I actually take away from this that colchicine is equivalent to prednisone for short-term use for CPP arthritis, but I think it’s also really important to note that this is in the context of quite a lot of acetaminophen and quite a lot of tramadol, and frankly I don’t usually use tramadol with my patients, but I might consider doing that, especially as there were no delirium events in this population.”

Dr. Tedeschi was not involved in the study.

Asked the same question, Michael Toprover, MD, from New York University Langone Medical Center, a moderator of the session who was not involved in the study, said: “I usually use a combination of medications. I generally, in someone who is hospitalized in particular and is in such severe pain, use a combination of colchicine and prednisone, unless I’m worried about infection, in which case I’ll start colchicine until we’ve proven that it’s CPPD, and then I’ll add prednisone.”

The study was funded by PHRC-1 GIRCI Nord Ouest, a clinical research program funded by the Ministry of Health in France. Dr. Pascart, Dr. Tedeschi, and Dr. Toprover all reported having no relevant conflicts of interest.

Of the 111 patients randomized, 54 were assigned to receive prednisone, and 57 were assigned to receive colchicine. Baseline characteristics were similar between the groups, with a mean age of about 86 years, body mass index of around 25 kg/m², and blood pressure in the range of 130/69 mm Hg.

For nearly half of all patients in study each arm the most painful joint was the knee, followed by wrists and ankles.

There was no difference between the groups in the primary efficacy outcome of a change at 24 hours over baseline in visual analog scale (VAS) (0-100 mm) scores, either in a per-protocol analysis or modified intention-to-treat analysis. The mean change in VAS at 24 hours in the colchicine group was –36.6 mm, compared with –37.7 mm in the prednisone group. The investigators had previously determined that any difference between the two drugs of less than 13 mm on pain VAS at 24 hours would meet the definition for equivalent efficacy.

In both groups, a majority of patients had either an improvement greater than 50% in pain VAS scores and/or a pain VAS score less than 40 mm at both 24 and 48 hours.

At 7 days of follow-up, 21.8% of patients assigned to colchicine had diarrhea, compared with 5.6% of those assigned to prednisone. Adverse events occurring more frequently with prednisone included hyperglycemia, hypertension, and insomnia.

Patients who received colchicine and were also on statins had a trend toward a higher risk for diarrhea, but the study was not adequately powered to detect an association, and the trend was not statistically significant, Dr. Pascart said.

“Taken together, safety issues suggest that prednisone should be considered as the first-line therapy in acute CPP crystal arthritis. Future research is warranted to determine factors increasing the risk of colchicine-induced diarrhea,” he concluded.
 

Both drugs are used

Sara K. Tedeschi, MD, from Brigham & Women’s Hospital in Boston, who attended the session where the data were presented, has a special clinical interest in CPP deposition disease. She applauded Dr. Pascart and colleagues for conducting a rare clinical trial in CPP crystal arthritis.

In an interview, she said that the study suggests “we can keep in mind shorter courses of treatment for acute CPP crystal arthritis; I think that’s one big takeaway from this study.”

Asked whether she would change her practice based on the findings, Dr. Tedeschi replied: “I personally am not sure that I would be moved to use prednisone more than colchicine; I actually take away from this that colchicine is equivalent to prednisone for short-term use for CPP arthritis, but I think it’s also really important to note that this is in the context of quite a lot of acetaminophen and quite a lot of tramadol, and frankly I don’t usually use tramadol with my patients, but I might consider doing that, especially as there were no delirium events in this population.”

Dr. Tedeschi was not involved in the study.

Asked the same question, Michael Toprover, MD, from New York University Langone Medical Center, a moderator of the session who was not involved in the study, said: “I usually use a combination of medications. I generally, in someone who is hospitalized in particular and is in such severe pain, use a combination of colchicine and prednisone, unless I’m worried about infection, in which case I’ll start colchicine until we’ve proven that it’s CPPD, and then I’ll add prednisone.”

The study was funded by PHRC-1 GIRCI Nord Ouest, a clinical research program funded by the Ministry of Health in France. Dr. Pascart, Dr. Tedeschi, and Dr. Toprover all reported having no relevant conflicts of interest.

PHILADELPHIA – Prednisone appears to have the edge over colchicine for control of pain in patients with acute calcium pyrophosphate (CPP) crystal arthritis, an intensely painful rheumatic disease primarily affecting older patients.

Among 111 patients with acute CPP crystal arthritis randomized to receive either prednisone or colchicine for control of acute pain in a multicenter study, 2 days of therapy with the oral agents provided equivalent pain relief on the second day, and patients generally tolerated each agent well, reported Tristan Pascart, MD, from the Groupement Hospitalier de l’Institut Catholique de Lille (France).

“Almost three-fourths of patients are considered to be good responders to both drugs on day 3, and, maybe, safety is the key issue distinguishing the two treatments: Colchicine was generally well tolerated, but even with this very short time frame of treatment, one patient out of five had diarrhea, which is more of a concern in this elderly population at risk of dehydration,” he said in an oral abstract session at the annual meeting of the American College of Rheumatology.

In contrast, only about 6% of patients assigned to prednisone had diarrhea, and other adverse events that occurred more frequently with the corticosteroid, including hypertension, hyperglycemia, and insomnia all resolved after the therapy was stopped.
 

Common and acutely painful

Acute CPP crystal arthritis is a common complication that often occurs during hospitalization for primarily nonrheumatologic causes, Dr. Pascart said, and “in the absence of clinical trials, the management relies on expert opinion, which stems from extrapolated data from gap studies” primarily with prednisone or colchicine, Dr. Pascart said.

To fill in the knowledge gap, Dr. Pascart and colleagues conducted the COLCHICORT study to evaluate whether the two drugs were comparable in efficacy and safety for control of acute pain in a vulnerable population.

The multicenter, open-label trial included patients older than age 65 years with an estimated glomerular filtration rate above 30 mL/min per 1.73 m² who presented with acute CPP deposition arthritis with symptoms occurring within the previous 36 hours. CPP arthritis was defined by the identification of CPP crystals on synovial fluid analysis or typical clinical presentation with evidence of chondrocalcinosis on x-rays or ultrasound.

Patients with a history of gout, cognitive decline that could impair pain assessment, or contraindications to either of the study drugs were excluded.

The participants were randomized to receive either colchicine 1.5 mg (1 mg to start, then 0.5 mg one hour later) at baseline and then 1 mg on day 1, or oral prednisone 30 mg at baseline and on day 1. The patients also received 1 g of systemic acetaminophen, and three 50-mg doses of tramadol during the first 24 hours.

PHILADELPHIA – Women with spondyloarthritis (SpA) who are desiring pregnancy may want to consider decreasing use or discontinuing use (with supervision) of nonsteroidal anti-inflammatory drugs before conception, new data suggest.

Researchers have found a connection between NSAID use and age and a significantly longer time to conception among women with spondyloarthritis. Sabrina Hamroun, MMed, with the rheumatology department at the University Hospital Cochin, Paris, presented the findings during a press conference at the annual meeting of the American College of Rheumatology.

Subfertility group took an average of 16 months to get pregnant

Subfertility was observed in 40 (45.4%) of the women, with an average time to conception of 16.1 months. A woman was considered subfertile if her time to conception was more than 12 months or if she did not become pregnant.

The average preconception Bath Ankylosing Spondylitis Disease Activity Index score was 2.9 (+/- 2.1), the authors noted. The average age of the participants was 32 years.

Twenty-three patients were treated with NSAIDs, eight with corticosteroids, 12 with conventional synthetic disease-modifying antirheumatic drugs, and 61 with biologics.

Researchers adjusted for factors including age, body mass index, disease duration and severity, smoking, form of SpA (axial, peripheral, or both), and medication in the preconception period.

They found significant associations between longer time to conception and age (hazard ratio, 1.22; 95% confidence interval, 1.08-1.40; P < .001), and a much higher hazard ratio with the use of NSAIDs during preconception (HR, 3.01; 95% CI, 2.15-3.85; P = .01).

Some data unavailable

Ms. Hamroun acknowledged that no data were available on the frequency of sexual intercourse or quality of life, factors that could affect time to conception. Women were asked when they discontinued contraceptive use and actively began trying to become pregnant.

She stated that information on the dose of NSAIDs used by the patients was incomplete, noting, “We were therefore unable to adjust the results of our statistical analyses on the dose used by patients.”

Additionally, because the study participants were patients at tertiary centers in France and had more severe disease, the results may not be generalizable to all women of childbearing age. Patients with less severe SpA are often managed in outpatient settings in France, she said.

When asked about alternatives to NSAIDs, Ms. Hamroun said that anti–tumor necrosis factor agents with low placental passage may be a good alternative “if a woman with long-standing difficulties to conceive needs a regular use of NSAIDs to control disease activity, in the absence of any other cause of subfertility.”

The patient’s age must also be considered, she noted.

“A therapeutic switch may be favored in a woman over 35 years of age, for example, whose fertility is already impaired by age,” Ms. Hamroun said.

As for the mechanism that might explain the effects of NSAIDs on conception, Ms. Hamroun said that prostaglandins are essential to ovulation and embryo implantation and explained that NSAIDs may work against ovulation and result in poor implantation (miscarriage) by blocking prostaglandins.

She pointed out that her results are in line with the ACR’s recommendation to discontinue NSAID use during the preconception period in women with SpA who are having difficulty conceiving.
 

Control before conception is important

Sinead Maguire, MD, a clinical and research fellow in the Spondylitis Program at Toronto (Ont.) Western Hospital who was not part of the study, said the study highlights the importance of optimizing disease control before conception.

“There are a number of things rheumatologists can do to support our SpA patients when they are trying to conceive,” she told this news organization. “One of the most important issues to address is ensuring their SpA is in remission and continues to remain so. For that reason, if a woman is requiring regular NSAIDs for symptom control, the results of this study might encourage me to consider a biologic agent sooner to ensure remission.”

She urged women who want to become pregnant to discuss medications with their rheumatologist before trying to conceive.

“It is very exciting to see studies such as this so that rheumatologists can provide answers to our patients’ questions with evidence-based advice,” she said.

Ms. Hamroun and several coauthors had no disclosures. Other coauthors disclosed relationships with companies including Merck/MSD, Novartis, Janssen, AbbVie/Abbott, Amgen, AstraZeneca, Biogen, Bristol-Myers Squibb, Galapagos, Eli Lilly, Novartis, and/or UCB. Dr. Maguire reports no relevant financial relationships.

PHILADELPHIA – Combining the immunomodulatory agent mycophenolate with the antifibrotic pirfenidone led to more rapid improvement and showed a trend to be more effective than mycophenolate mofetil alone for treating the signs and symptoms of scleroderma-related interstitial lung disease, but the combination therapy came with an increase in side effects, according to results from the Scleroderma Lung Study III.

Dinesh Khanna, MBBS, MSc, of the University of Michigan, Ann Arbor, presented the results at the annual meeting of the American College of Rheumatology. He noted some problems with the study – namely its small size, enrolling only 51 patients, about one-third of its original goal. But he also said it showed a potential signal for efficacy and that the study itself could serve as a “template” for future studies of combination mycophenolate mofetil (MMF) plus pirfenidone therapy for scleroderma-related interstitial lung disease (SSc-ILD).

“The pirfenidone patients had quite a bit more GI side effects and photosensitivity, and those are known side effects,” Dr. Khanna said in an interview. “So the combination therapy had more side effects but trends to higher efficacy.”

The design of SLS-III, a phase 2 clinical trial, was a challenge, Dr. Khanna explained. The goal was to enroll 150 SSc-ILD patients who hadn’t had any previous treatment for their disease. Finding those patients proved difficult. “In fact, if you look at the recent history, 70% of the patients with early diffuse scleroderma are on MMF,” he said in his presentation. Compounding low study enrollment was the intervening COVID-19 pandemic, he added.
 

Testing a faster-acting combination

Nonetheless, the trial managed to enroll 27 patients in the combination therapy group and 24 in the MMF-plus-placebo group and compared their outcomes over 18 months. Study dosing was 1,500 mg MMF twice daily and pirfenidone 801 mg three times daily, titrated to the tolerable dose.

Despite the study’s being underpowered, Dr. Khanna said, it still reported some notable outcomes that merit further investigation. “I think what was intriguing in the study was the long-term benefit in the patient-reported outcomes and the structural changes,” he said in the interview.

Among those notable outcomes was a clinically significant change in forced vital capacity (FVC) percentage for the combination vs. the placebo groups: 2.24% vs. 2.09%. He also noted that the combination group saw a somewhat more robust improvement in FVC at six months: 2.59% (± 0.98%) vs. 0.92% (± 1.1%) in the placebo group.

The combination group showed greater improvements in high-resolution computed tomography-evaluated lung involvement and lung fibrosis and patient-reported outcomes, including a statistically significant 3.67-point greater improvement in PROMIS-29 physical function score (4.42 vs. 0.75).

The patients on combination therapy had higher rates of serious adverse events (SAEs), and seven discontinued one or both study drugs early, all in the combined arm. Four combination therapy patients had six SAEs, compared to two placebo patients with three SAEs. In the combination group, SAEs included chest pain, herpes zoster ophthalmicus, nodular basal cell cancer, marginal zone B cell lymphoma, renal crisis, and dyspnea. SAEs in the placebo group were colitis, COVID-19 and hypoxic respiratory failure.

Study design challenges

Nonetheless, Dr. Khanna said the SLS-III data are consistent with the SLS-II findings, with mean improvements in FVC of 2.24% and 2.1%, respectively.

“The next study may be able to replicate what we tried to do, keeping in mind that there are really no MMF-naive patients who are walking around,” Dr. Khanna said. “So the challenge is about the feasibility of recruiting within a trial vs. trying to show a statistical difference between the drug and placebo.”

This study could serve as a foundation for future studies of MMF in patients with SSc-ILD, Robert Spiera, MD, of the Hospital for Special Surgery in New York, said in an interview. “There are lessons to be learned both from the study but also from prior studies looking at MMF use in the background in patients treated with other drugs in clinical trials,” he said.

Dr. Spiera noted that the study had other challenges besides the difficulty in recruiting patients who hadn’t been on MMF therapy. “A great challenge is that the benefit with regard to the impact on the lungs from MMF seems most prominent in the first 6 months to a year to even 2 years that somebody is on the drug,” he said.

The other challenge with this study is that a large proportion of patients had limited systemic disease and relatively lower levels of skin disease compared with other studies of patients on MMF, Dr. Spiera said.

“The optimal treatment of scleroderma-associated lung disease remains a very important and not-adequately met need,” he said. “Particularly, we’re looking for drugs that are tolerable in a patient population that are very prone to GI side effects in general. This study and others have taught us a lot about trial design, and I think more globally this will allow us to move this field forward.”

Dr. Khanna disclosed relationships with Actelion, Boehringer Ingelheim, Bristol-Myers Squibb, CSL Behring, Horizon Therapeutics USA, Janssen Global Services, Prometheus Biosciences, Mitsubishi Tanabe Pharma Corp., Genentech/Roche, Theraly, and Pfizer. Genentech provided funding for the study and pirfenidone and placebo drugs at no cost.

Dr. Spiera disclosed relationships with GlaxoSmithKline, Boehringer-Ingelheim, Corbus Pharmaceutical, InflaRx, AbbVie/Abbott, Sanofi, Novartis, Chemocentryx, Roche and Vera.

“The optimal treatment of scleroderma-associated lung disease remains a very important and not-adequately met need,” he said. “Particularly, we’re looking for drugs that are tolerable in a patient population that are very prone to GI side effects in general. This study and others have taught us a lot about trial design, and I think more globally this will allow us to move this field forward.”

PHILADELPHIA – Combining the immunomodulatory agent mycophenolate with the antifibrotic pirfenidone led to more rapid improvement and showed a trend to be more effective than mycophenolate mofetil alone for treating the signs and symptoms of scleroderma-related interstitial lung disease, but the combination therapy came with an increase in side effects, according to results from the Scleroderma Lung Study III.

Dinesh Khanna, MBBS, MSc, of the University of Michigan, Ann Arbor, presented the results at the annual meeting of the American College of Rheumatology. He noted some problems with the study – namely its small size, enrolling only 51 patients, about one-third of its original goal. But he also said it showed a potential signal for efficacy and that the study itself could serve as a “template” for future studies of combination mycophenolate mofetil (MMF) plus pirfenidone therapy for scleroderma-related interstitial lung disease (SSc-ILD).

“The pirfenidone patients had quite a bit more GI side effects and photosensitivity, and those are known side effects,” Dr. Khanna said in an interview. “So the combination therapy had more side effects but trends to higher efficacy.”

The design of SLS-III, a phase 2 clinical trial, was a challenge, Dr. Khanna explained. The goal was to enroll 150 SSc-ILD patients who hadn’t had any previous treatment for their disease. Finding those patients proved difficult. “In fact, if you look at the recent history, 70% of the patients with early diffuse scleroderma are on MMF,” he said in his presentation. Compounding low study enrollment was the intervening COVID-19 pandemic, he added.
 

Testing a faster-acting combination

Nonetheless, the trial managed to enroll 27 patients in the combination therapy group and 24 in the MMF-plus-placebo group and compared their outcomes over 18 months. Study dosing was 1,500 mg MMF twice daily and pirfenidone 801 mg three times daily, titrated to the tolerable dose.

Despite the study’s being underpowered, Dr. Khanna said, it still reported some notable outcomes that merit further investigation. “I think what was intriguing in the study was the long-term benefit in the patient-reported outcomes and the structural changes,” he said in the interview.

Among those notable outcomes was a clinically significant change in forced vital capacity (FVC) percentage for the combination vs. the placebo groups: 2.24% vs. 2.09%. He also noted that the combination group saw a somewhat more robust improvement in FVC at six months: 2.59% (± 0.98%) vs. 0.92% (± 1.1%) in the placebo group.

The combination group showed greater improvements in high-resolution computed tomography-evaluated lung involvement and lung fibrosis and patient-reported outcomes, including a statistically significant 3.67-point greater improvement in PROMIS-29 physical function score (4.42 vs. 0.75).

The patients on combination therapy had higher rates of serious adverse events (SAEs), and seven discontinued one or both study drugs early, all in the combined arm. Four combination therapy patients had six SAEs, compared to two placebo patients with three SAEs. In the combination group, SAEs included chest pain, herpes zoster ophthalmicus, nodular basal cell cancer, marginal zone B cell lymphoma, renal crisis, and dyspnea. SAEs in the placebo group were colitis, COVID-19 and hypoxic respiratory failure.

Study design challenges

Nonetheless, Dr. Khanna said the SLS-III data are consistent with the SLS-II findings, with mean improvements in FVC of 2.24% and 2.1%, respectively.

“The next study may be able to replicate what we tried to do, keeping in mind that there are really no MMF-naive patients who are walking around,” Dr. Khanna said. “So the challenge is about the feasibility of recruiting within a trial vs. trying to show a statistical difference between the drug and placebo.”

This study could serve as a foundation for future studies of MMF in patients with SSc-ILD, Robert Spiera, MD, of the Hospital for Special Surgery in New York, said in an interview. “There are lessons to be learned both from the study but also from prior studies looking at MMF use in the background in patients treated with other drugs in clinical trials,” he said.

Dr. Spiera noted that the study had other challenges besides the difficulty in recruiting patients who hadn’t been on MMF therapy. “A great challenge is that the benefit with regard to the impact on the lungs from MMF seems most prominent in the first 6 months to a year to even 2 years that somebody is on the drug,” he said.
