Clinician Reviews

A common food dye found in candy, soft drinks, and some cereals, known as Allura Red, can lead to inflammatory bowel diseases, Crohn’s disease, and other health problems, new research shows.

Long-term ingestion of the dye disrupts gut function, causing a series of changes that lead to a higher risk of colitis, according to the research from McMaster University, Hamilton, Ont. The findings were published in Nature Communications.

The dye is also known as FD&C Red 40 and Food Red 17. It adds color and texture and is often used to attract children, according to a press release on Eurekalert.

“This study demonstrates significant harmful effects of Allura Red on gut health and identifies gut serotonin as a critical factor mediating these effects. These findings have important implications in the prevention and management of gut inflammation,” said senior author Waliul Khan, MBBS, PhD, a professor in the McMaster department of pathology and molecular medicine.

“What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs,” he said. “The literature suggests that the consumption of Allura Red also affects certain allergies, immune disorders, and behavioural problems in children, such as attention deficit hyperactivity disorder.”

The human diet in Western cultures, with its reliance on processed fats, red and processed meat, and low fiber, contributes to IBDs as well, Dr. Khan said.

Food dyes such as Allura Red have been used more and more in recent years. Their effect on gut health hasn’t been studied much.

A year ago in December, mapping specialist Whitney Tyshynski, 35, was working out 5 days a week with a personal trainer near her home in Alberta, Canada, doing 5k trail runs, lifting heavy weights, and feeling good. Then, in January she got COVID-19. The symptoms never went away.
 

Nowadays, Ms. Tyshynski needs a walker to retrieve her mail, a half-block trip she can’t make without fear of fainting. Because she gets dizzy when she drives, she rarely goes anywhere in her car. Going for a dog walk with a friend means sitting in a car and watching the friend and the dogs in an open field. And since fainting at Costco during the summer, she’s afraid to shop by herself.

Because she lives alone and her closest relatives are an hour and a half away, Ms. Tyshynski is dependent on friends. But she’s reluctant to lean on them because they already have trouble understanding how debilitating her lingering symptoms can be.

“I’ve had people pretty much insinuate that I’m lazy,” she says.

There’s no question that COVID-19 cut people off from one another. But for those like Ms. Tyshynski who have long COVID, that disconnect has never ended. It’s not just that symptoms including extreme fatigue and brain fog make it difficult to socialize; it’s that people who had COVID-19 and recovered are often skeptical that the condition is real.

At worst, as Ms. Tyshynski has discovered, people don’t take it seriously and accuse those who have it of exaggerating their health woes. In that way, long COVID can be as isolating as the original illness.

“Isolation in long COVID comes in various forms and it’s not primarily just that physical isolation,” says Yochai Re’em, MD, a psychiatrist in private practice in New York who has experienced long COVID and blogs about the condition for Psychology Today. “A different yet equally challenging type of isolation is the emotional isolation, where you need more emotional support, connection with other people who can appreciate what it is you are going through without putting their own needs and desires onto you – and that can be hard to find.”

It’s hard to find in part because of what Dr. Re’em sees as a collective belief that anyone who feels bad should be able to get better by exercising, researching, or going to a doctor.

“Society thinks you need to take some kind of action and usually that’s a physical action,” he says. “And that attitude is tremendously problematic in this illness because of the postexertional malaise that people experience: When people exert themselves, their symptoms get worse. And so the action that people take can’t be that traditional action that we’re used to taking in our society.”

Long COVID patients often have their feelings invalidated not just by friends, loved ones, and extended family, but by health care providers. That can heighten feelings of isolation, particularly for people who live alone, says Jordan Anderson, DO, a neuropsychiatrist and assistant professor of psychiatry at Oregon Health & Science University in Portland.

The first patients Dr. Anderson saw as part of OHSU’s long COVID program contracted the virus in February 2020. Because the program addresses both the physical and mental health components of the condition, Dr. Anderson has seen a lot of people whose emotional challenges are similar to those Ms. Tyshynski faces.

“I think there’s a lack of understanding that leads to people just not necessarily taking it seriously,” he says. “Plus, the symptoms of long COVID do wax and wane. They’re not static. So people can be feeling pretty good one day and be feeling terrible the next. There’s some predictability to it, but it’s not absolutely predictable. It can be difficult for people to understand.”

Both Dr. Anderson and Dr. Re’em stress that long COVID patients need to prioritize their own energy regardless of what they’re being told by those who don’t understand the illness. Dr. Anderson offers to speak to his patients’ spouses to educate them about the realities of the condition because, he says, “any kind of lack of awareness or understanding in a family member or close support could potentially isolate the person struggling with long COVID.”

Depending on how open-minded and motivated a friend or relative is, they might develop more empathy with time and education, Dr. Re’em says. But for others, dealing with a confusing, unfamiliar chronic illness can be overwhelming and provoke anxiety.

“The hopelessness is too much for them to sit with, so instead they say things like ‘just push through it,’ or ‘just do X, Y, and Z,’ because psychologically it’s too much for them to take on that burden,” he says.

The good news is that there are plenty of web-based support groups for people with long COVID, including Body Politic (which Dr. Re’em is affiliated with), Survivor Corps, and on Facebook. “The patient community with this illness is tremendous, absolutely tremendous,” Dr. Re’em says. “Those people can be found and they can support each other.”

Some long COVID clinics run groups, as do individual practitioners such as Dr. Re’em, although those can be challenging to join. For instance, Dr. Re’em’s are only for New York state residents.

The key to finding a group is to be patient, because finding the right one takes time and energy.

“There are support groups that exist, but they are not as prevalent as I would like them to be,” Dr. Anderson says.

OHSU had an educational support group run by a social worker affiliated with the long COVID hub, but when the social worker left the program, the program was put on hold.

There’s a psychotherapy group operating out of the psychiatry department, but the patients are recruited exclusively from Dr. Anderson’s clinic and access is limited.

“The services exist, but I think that generally they’re sparse and pretty geographically dependent,” Dr. Anderson says. “I think you’d probably more likely be able to find something like this in a city or an area that has an academic institution or a place with a lot of resources rather than out in a rural community.”

Ms. Tyshynski opted not to join a group for fear it would increase the depression and anxiety that she had even before developing long COVID. When she and her family joined a cancer support group when her father was ill, she found it more depressing than helpful. Where she has found support is from the cofounder of the animal rescue society where she volunteers, a woman who has had long COVID for more than 2 years and has been a source of comfort and advice.

It’s one of the rare reminders Ms. Tyshynski has that even though she may live alone, she’s not completely alone. “Other people are going through this, too,” she says. “It helps to remember that.”

The U.S. Food and Drug Administration has approved the medication lenacapavir (Sunlenca) for adults living with multidrug resistant HIV-1 infection. After the initial doses are completed – given both orally and via subcutaneous injection – the drug is administered by injection every 6 months.
 

“Following today’s decision from the FDA, lenacapavir helps to fill a critical unmet need for people with complex prior treatment histories and offers physicians a long-awaited twice-yearly option for these patients who otherwise have limited therapy choices,” said site principal investigator Sorana Segal-Maurer, MD, a professor of clinical medicine at Weill Cornell Medicine, New York, in a statement.

HIV drug regimens generally consist of two or three HIV medicines combined in a daily pill. In 2021, the FDA approved the first injectable complete drug regimen for HIV-1, Cabenuva, which can be administered monthly or every other month. Lenacapavir is administered only twice annually, but it is also combined with other antiretrovirals. The injections and oral tablets of lenacapavir are estimated to cost $42,250 in the first year of treatment and then $39,000 annually in the subsequent years, Reuters reported.

Lenacapavir is the first of a new class of drug called capsid inhibitors to be FDA-approved for treating HIV-1. The drug blocks the HIV-1 virus’s protein shell and interferes with essential steps of the virus’s evolution. The approval, announced today, was based on a multicenter clinical trial of 72 patients with multidrug resistant HIV-1 infection. After a year of the medication, 30 (83%) of the 36 patients randomly assigned to take lenacapavir, in combination with other HIV medications, had undetectable viral loads.

“Today’s approval ushers in a new class of antiretroviral drugs that may help patients with HIV who have run out of treatment options,” said Debra Birnkrant, MD, director of the division of antivirals in the FDA’s Center for Drug Evaluation and Research, in a press release. “The availability of new classes of antiretroviral medications may possibly help these patients live longer, healthier lives.”

NEW ORLEANS – Addressing an audience of hematologists, an immunologist and a thrombosis specialist presented insights on two hot COVID-19 topics: strategies the virus uses to breach the immune system and the diagnosis and treatment of vaccine-related blood clots.

In a presidential symposium at the annual meeting of the American Society of Hematology, La Jolla Institute of Immunology scientist Shane Crotty, PhD, explained that COVID-19 has a “superpower” that allows it to be “extraordinarily stealthy.”

The virus, he said, can sneak past the body’s innate immune system, which normally responds to viral invaders within minutes to hours. “This is why you have people with high viral loads who are presymptomatic. Their innate immune system hasn’t even recognized that these people are infected.”

The adaptive immune system kicks in later. As Dr. Crotty noted, adaptive immunity is composed of three branches: B cells (the source of antibodies), CD4 “helper” T cells, and CD8 “killer” T cells. In the first year of COVID-19, his team tracked 188 subjects post infection in what he said was the largest study of its kind ever for any viral infection.

“In 8 months, 95% of people who had been infected still had measurable immune memory. In fact, most of them had multiple different compartments of immune memory still detectable, and it was likely that these individuals would still have that memory years into the future. Based on that, we made the prediction that most people who have had COVID-19 would likely be protected from reinfection – at least by severe infections – for 3 years into the future. That prediction has widely held up even in the presence of variants which weren’t around at the time.”

How do vaccines fit into the immunity picture? Dr. Crotty’s lab has tracked subjects who received 4 vaccines – Moderna, Pfizer/BioNTech, Janssen/Johnson & Johnson, and Novavax. Researchers found that the mRNA vaccines, Moderna and Pfizer/BioNTech, “are fantastic at eliciting neutralizing antibodies quickly, but then they drop off rapidly at two doses and actually continue to drop for 10 months.”

Still, he said, “when we take a look at 6 months, actually the vaccines are doing pretty incredibly well. If we compare them to an average infected individual, the mRNA vaccines all have higher neutralizing antibody titers.”

What’s happening? According to Dr. Crotty, B cells are “making guesses about what other variants might look like.” But he said research suggests that an important component of this process – germinal centers – aren’t made in some vaccinated people who are immunocompromised. (Germinal centers have been described as “microbial boot camps” for B cells.)

The good news, Dr. Crotty noted, is that a greater understanding of how COVID-19 penetrates various layers of adaptive immune defenses will lead to better ways to protect the immunocompromised. “If you think about immunity in this layered defense way, there are various ways that it could be enhanced for individuals in different categories,” he said.

Hematologist Beverley J. Hunt, MD, OBE, of St. Thomas’ Hospital/King’s Healthcare Partners in London, spoke at the ASH presidential symposium about blood clots and COVID-19. As she noted, concern arose about vaccine-related blood clots. A British team “managed quickly to come up with a diagnostic criteria,” she said. “We looked at nearly 300 patients and essentially came up with a scoring system.”

The diagnostic criteria was based on an analysis of definite or probable cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) – all related to the AstraZeneca vaccine. The criteria appeared in a 2021 study in the New England Journal of Medicine.

The report’s data didn’t allow it to compare the efficacy of anticoagulants. However, Dr. Hunt noted that clinicians turned to plasma exchange in patients with low platelet counts and extensive thrombosis. The report stated “survival after plasma exchange was 90%, considerably better than would be predicted given the baseline characteristics.”

NEW ORLEANS – Addressing an audience of hematologists, an immunologist and a thrombosis specialist presented insights on two hot COVID-19 topics: strategies the virus uses to breach the immune system and the diagnosis and treatment of vaccine-related blood clots.

In a presidential symposium at the annual meeting of the American Society of Hematology, La Jolla Institute of Immunology scientist Shane Crotty, PhD, explained that COVID-19 has a “superpower” that allows it to be “extraordinarily stealthy.”

The virus, he said, can sneak past the body’s innate immune system, which normally responds to viral invaders within minutes to hours. “This is why you have people with high viral loads who are presymptomatic. Their innate immune system hasn’t even recognized that these people are infected.”

The adaptive immune system kicks in later. As Dr. Crotty noted, adaptive immunity is composed of three branches: B cells (the source of antibodies), CD4 “helper” T cells, and CD8 “killer” T cells. In the first year of COVID-19, his team tracked 188 subjects post infection in what he said was the largest study of its kind ever for any viral infection.

“In 8 months, 95% of people who had been infected still had measurable immune memory. In fact, most of them had multiple different compartments of immune memory still detectable, and it was likely that these individuals would still have that memory years into the future. Based on that, we made the prediction that most people who have had COVID-19 would likely be protected from reinfection – at least by severe infections – for 3 years into the future. That prediction has widely held up even in the presence of variants which weren’t around at the time.”

How do vaccines fit into the immunity picture? Dr. Crotty’s lab has tracked subjects who received 4 vaccines – Moderna, Pfizer/BioNTech, Janssen/Johnson & Johnson, and Novavax. Researchers found that the mRNA vaccines, Moderna and Pfizer/BioNTech, “are fantastic at eliciting neutralizing antibodies quickly, but then they drop off rapidly at two doses and actually continue to drop for 10 months.”

Still, he said, “when we take a look at 6 months, actually the vaccines are doing pretty incredibly well. If we compare them to an average infected individual, the mRNA vaccines all have higher neutralizing antibody titers.”

What’s happening? According to Dr. Crotty, B cells are “making guesses about what other variants might look like.” But he said research suggests that an important component of this process – germinal centers – aren’t made in some vaccinated people who are immunocompromised. (Germinal centers have been described as “microbial boot camps” for B cells.)

The good news, Dr. Crotty noted, is that a greater understanding of how COVID-19 penetrates various layers of adaptive immune defenses will lead to better ways to protect the immunocompromised. “If you think about immunity in this layered defense way, there are various ways that it could be enhanced for individuals in different categories,” he said.

Hematologist Beverley J. Hunt, MD, OBE, of St. Thomas’ Hospital/King’s Healthcare Partners in London, spoke at the ASH presidential symposium about blood clots and COVID-19. As she noted, concern arose about vaccine-related blood clots. A British team “managed quickly to come up with a diagnostic criteria,” she said. “We looked at nearly 300 patients and essentially came up with a scoring system.”

The diagnostic criteria was based on an analysis of definite or probable cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) – all related to the AstraZeneca vaccine. The criteria appeared in a 2021 study in the New England Journal of Medicine.

The report’s data didn’t allow it to compare the efficacy of anticoagulants. However, Dr. Hunt noted that clinicians turned to plasma exchange in patients with low platelet counts and extensive thrombosis. The report stated “survival after plasma exchange was 90%, considerably better than would be predicted given the baseline characteristics.”

“Now we’re following up,” Dr. Hunt said. One question to answer: Is long-term anticoagulation helpful? “We have many patients,” she said, “who are taking an anti-platelet factor out of habit.”

Fecal microbiota transplantation (FMT) does not appear to contribute to weight loss for patients who undergo bariatric surgery, according to results of a randomized controlled trial.

The small study by Perttu Lahtinen, MD, with Päijät-Häme Central Hospital in Lahti, Finland, and colleagues was published online in JAMA Network Open.

Bariatric surgery remains the most effective strategy for treating severe obesity. Yet some patients achieve only minimal weight loss or regain weight after surgery, the researchers noted.

There is much interest in the gut microbiota as a potential target for the treatment of obesity. FMT from a lean donor has shown promise in treating obesity in mouse models (Science. 2013 Sep 6. doi: 10.1126/science.1241214).

The Finnish trial, however, does not support that conclusion.

The study included 41 adults (71% women; mean age, 48.7 years) with severe obesity (mean body mass index, 42.5 kg/m²). Twenty-one received FMT from a lean donor, and 20 received FMT from their own feces (autologous placebo). FMT was administered by gastroscopy into the duodenum 6 months before laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy. All patients also consumed a very-low-calorie diet approximately 4 weeks before the surgery.

Bariatric surgery led to equal weight reductions for both groups, but there was no additive benefit in terms of weight loss with FMT.

Six months after the administration of FMT, and before the surgery was performed, the percentage of total weight loss, the main outcome, was 4.8% (P < .001) in the FMT group and 4.6% (P = .006) in the placebo group. There was no statistically significant difference between the groups (absolute difference, 0.2%).

At 18 months (12 months after surgery), the percentage of total weight loss was 25.3% (P < .001) in the FMT group and 25.2% (P < .001) in the placebo group – an absolute difference of 0.1%.

The researchers said the main limitation of their study is the small number of patients. Because there were few patients, the study may be inadequate to show possible minor effects of FMT on weight; it’s unclear whether a much larger sample size would have yielded any differences between the groups.

Nonetheless, the study suggests that FMT does not affect weight loss for patients who undergo bariatric surgery, the researchers said.

The study was supported by governmental research grants and the Sigrid Juselius Foundation. The authors disclosed no relevant financial relationships.

Nonheavy alcohol use – fewer than 14 drinks per week for women and fewer than 21 drinks per week for men – is associated with liver fibrosis and nonalcoholic steatohepatitis (NASH), according to a new report.

An analysis of current drinkers in the Framingham Heart Study found that a higher number of drinks per week and higher frequency of drinking were associated with increased odds of fibrosis among patients whose consumption fell below the threshold for heavy alcohol use.

“Although the detrimental effects of heavy alcohol use are well accepted, there is no consensus guideline on how to counsel patients about how nonheavy alcohol use may affect liver health,” Brooke Rice, MD, an internal medicine resident at Boston University, said in an interview.

“Current terminology classifies fatty liver disease as either alcoholic or nonalcoholic,” she said. “Our results call this strict categorization into question, suggesting that even nonheavy alcohol use should be considered as a factor contributing to more advanced nonalcoholic fatty liver disease [NAFLD] phenotypes.”

The study was published online in Clinical Gastroenterology and Hepatology.
 

Analyzing associations

NAFLD and alcohol-related liver disease, which are the most common causes of chronic liver disease worldwide, are histologically identical but distinguished by the presence of significant alcohol use, the study authors wrote.

Heavy alcohol use, based on guidelines from the American Association for the Study of Liver Diseases, is defined as more than 14 drinks per week for women or more than 21 drinks per week for men.

Although heavy alcohol use is consistently associated with cirrhosis and steatohepatitis, studies of nonheavy alcohol use have shown conflicting results, the authors wrote. However, evidence suggests that the pattern of alcohol consumption – particularly increased weekly drinking and binge drinking – may be an important predictor.

Dr. Rice and colleagues conducted a cross-sectional study of 2,629 current drinkers in the Framingham Heart Study who completed alcohol-use questionnaires and vibration-controlled transient elastography between April 2016 and April 2019. They analyzed the association between fibrosis and several alcohol-use measures, including total consumption and drinking patterns, among nonheavy alcohol users whose liver disease would be classified as “nonalcoholic” by current nomenclature.

The research team defined clinically significant fibrosis as a liver stiffness measurement of 8.2 kPa or higher. For at-risk NASH, the researchers used two FibroScan-AST (FAST) score thresholds – greater than 0.35 or 0.67 and higher. They also considered additional metabolic factors such as physical activity, body mass index, blood pressure, glucose measures, and metabolic syndrome.

Participants were asked to estimate the frequency of alcohol use (average number of drinking days per week during the past year) and the usual quantity of alcohol consumed (average number of drinks on a typical drinking day during the past year). Researchers multiplied the figures to estimate the average total number of drinks per week.

Among the 2,629 current drinkers (53% women, 47% men), the average age was 54 years, 7.2% had diabetes, and 26.9% met the criteria for metabolic syndrome. Participants drank about 3 days per week on average with a usual consumption of two drinks per drinking day, averaging a total weekly alcohol consumption of six drinks.

The average liver stiffness measurement was 5.6 kPa, and 8.2% had significant fibrosis.

At the FAST score threshold of 0.67 or greater, 1.9% of participants were likely to have at-risk NASH, with a higher prevalence in those with obesity (4.5%) or diabetes (9.5%). At the FAST score threshold of greater than 0.35, the prevalence of at-risk NASH was 12.4%, which was higher in those with obesity (26.3%) or diabetes (34.4%).

Overall, an increased total number of drinks per week and higher frequency of drinking days were associated with increased odds of fibrosis.

Almost 17.5% of participants engaged in risky weekly drinking, which was defined as 8 or more drinks per week for women and 15 or more drinks per week for men. Risky weekly drinking was also associated with higher odds of fibrosis.

After excluding 158 heavy drinkers, the prevalence of fibrosis was unchanged at 8%, and an increased total of drinks per week remained significantly associated with fibrosis.

In addition, multiple alcohol-use measures were positively associated with a FAST score greater than 0.35 and were similar after excluding heavy alcohol users. These measures include the number of drinks per week, the frequency of drinking days, and binge drinking.

“We showed that nonheavy alcohol use is associated with fibrosis and at-risk NASH, which are both predictors of long-term liver-related morbidity and mortality,” Dr. Rice said.
 

Implications for patient care

The findings have important implications for both NAFLD clinical trials and patient care, the study authors wrote. For instance, the U.S. Dietary Guidelines for Americans recommend limiting alcohol use to one drink per day for women and two drinks per day for men.

“Our results reinforce the importance of encouraging all patients to reduce alcohol intake as much as possible and to at least adhere to current U.S. Dietary Guidelines recommended limits,” Dr. Rice said. “Almost half of participants in our study consumed in excess of these limits, which strongly associated with at-risk NASH.”

Additional long-term studies are needed to determine the benefits of limiting alcohol consumption to reduce liver-related morbidity and mortality, the authors wrote.

The effect of alcohol consumption on liver health “has been controversial, since some studies have suggested that nonheavy alcohol use can even have some beneficial metabolic effects and has been associated with reduced risk of fatty liver disease, while other studies have found that nonheavy alcohol use is associated with increased risk for liver-related clinical outcomes,” Fredrik Åberg, MD, PhD, a hepatologist and liver transplant specialist at Helsinki University Hospital, said in an interview.

Dr. Åberg wasn’t involved with this study but has researched alcohol consumption and liver disease. Among non–heavy alcohol users, drinking more alcohol per week is associated with increased hospitalization for liver disease, hepatocellular carcinoma, and liver-related death, he and his colleagues have found.

“We concluded that the net effect of non-heavy drinking on the liver is harm,” he said. “Overall, this study by Rice and colleagues supports the recommendation that persons with mild liver disease should reduce their drinking, and persons with severe liver disease (cirrhosis and advanced fibrosis) should abstain from alcohol use.”

The study authors are supported in part by the National Institute of Diabetes and Digestive and Kidney Diseases, a Doris Duke Charitable Foundation Grant, a Gilead Sciences Research Scholars Award, the Boston University Department of Medicine Career Investment Award, and the Boston University Clinical Translational Science Institute. The Framingham Heart Study is supported in part by the National Heart, Lung, and Blood Institute. The authors and Dr. Åberg reported no relevant financial relationships.

“Our results reinforce the importance of encouraging all patients to reduce alcohol intake as much as possible and to at least adhere to current U.S. Dietary Guidelines recommended limits,” Dr. Rice said. “Almost half of participants in our study consumed in excess of these limits, which strongly associated with at-risk NASH.”

Additional long-term studies are needed to determine the benefits of limiting alcohol consumption to reduce liver-related morbidity and mortality, the authors wrote.

The effect of alcohol consumption on liver health “has been controversial, since some studies have suggested that nonheavy alcohol use can even have some beneficial metabolic effects and has been associated with reduced risk of fatty liver disease, while other studies have found that nonheavy alcohol use is associated with increased risk for liver-related clinical outcomes,” Fredrik Åberg, MD, PhD, a hepatologist and liver transplant specialist at Helsinki University Hospital, said in an interview.

Dr. Åberg wasn’t involved with this study but has researched alcohol consumption and liver disease. Among non–heavy alcohol users, drinking more alcohol per week is associated with increased hospitalization for liver disease, hepatocellular carcinoma, and liver-related death, he and his colleagues have found.

“We concluded that the net effect of non-heavy drinking on the liver is harm,” he said. “Overall, this study by Rice and colleagues supports the recommendation that persons with mild liver disease should reduce their drinking, and persons with severe liver disease (cirrhosis and advanced fibrosis) should abstain from alcohol use.”

The study authors are supported in part by the National Institute of Diabetes and Digestive and Kidney Diseases, a Doris Duke Charitable Foundation Grant, a Gilead Sciences Research Scholars Award, the Boston University Department of Medicine Career Investment Award, and the Boston University Clinical Translational Science Institute. The Framingham Heart Study is supported in part by the National Heart, Lung, and Blood Institute. The authors and Dr. Åberg reported no relevant financial relationships.

A smartphone chatbot that gives lifestyle advice may help people with nonalcoholic steatohepatitis (NASH) improve their liver health, researchers say.

After 48 weeks, nonalcoholic fatty liver disease activity scores (NAS) improved in 13 out of 19 patients who used the NASH app developed by CureApp, according to Masaya Sato of the University of Tokyo and colleagues.

If confirmed by a controlled trial, these preliminary results could show promise for digital therapeutics, the researchers stated in an article published in The American Journal of Gastroenterology.

“The widespread use of smartphones, which can process and communicate data in real time, makes them an ideal platform for therapeutic interventions,” they said.

Although lifestyle changes can reduce NASH activity, many patients have difficulty keeping up these changes. Not enough counselors are available to guide patients in healthy practices, and hiring the counselors is expensive, the researchers wrote.

Smartphone applications aimed at instilling healthy behavior have been tried in diabetes, smoking, hypertension, alcoholism, and even cancer, they noted. They wanted to see whether something similar could be done with NASH.

The researchers recruited 19 patients with biopsy-confirmed NASH who consumed no more than moderate amounts of alcohol and had a body mass index (BMI) of at least 25 kg/m². Their mean age was 52 years, mean BMI was 32, and mean NAS was 5.0.

The patients downloaded the NASH app onto their phones and entered their baseline profile information, including age, gender, diet and exercise practices, and social characteristics. On the basis of this information and daily weight measurements, the system proposed lifestyle improvement programs tailored to each individual. Its chatbot presented them in the form of behavioral goals and lectures from virtual nurses.

While patients used the app for 48 weeks, they also received standard outpatient care for NASH from live physicians, who also promoted the use of the app and provided additional education related to NASH.

The patients underwent liver biopsies within 90 days prior to beginning the study and at the end of 48 weeks. The researchers compared the changes in these patients versus those in a hypothetical control group, which they based on the placebo group in a previous study.

In the patients who used the app, the mean NAS change from baseline to week 48, the main endpoint, was –2.05 (95% confidence interval, –3.00 to –1.11). This result was statistically significant compared with the hypothetical control group, in which the mean change in NAS was –0.7 (P < .001).

In 11 of the patients, NAS decreased by at least 2 points without worsening of liver fibrosis. In eight patients, the researchers observed resolution of steatohepatitis, which they defined as disappearance of hepatocyte ballooning.

In 12 patients with stage F2 or F3 fibrosis, the average stage went from 2.5 to 2.0 (P = .02). No patient with stage F1 fibrosis showed a reduction in fibrosis stage. The scores for steatosis decreased in 11 patients, for lobular inflammation in 9 patients, and for ballooning in 10 patients.

The patients lost an average of 8.3% of their body weight, which was significant, compared with their baseline (P < .001). The patients also notched significant reductions in average serum levels of AST, ALT, gamma-glutamyltransferase, alkaline phosphatase, and triglycerides.

The researchers noted that the lack of a real control group and the small size of the study population limited the importance of their findings. A larger randomized, controlled trial is needed to confirm their results.

During the study, physicians browsed the patients’ data and provided them with feedback about it, the researchers wrote. But the study did not measure the amount of time the physicians spent on this activity.

CureApp founded the study, and one of the authors is a consultant for the company.

Some solid food diets may aid in the treatment of inflammatory bowel disease (IBD), though the overall quality of evidence remains low and additional data are needed, according to a new report.

For Crohn’s disease, a diet low in refined carbohydrates and a symptoms-guided diet appeared to help with remission, yet reduction of refined carbohydrates or red meat didn’t reduce the risk of relapse. For ulcerative colitis, solid food diets were similar to control measures.

“The Internet has a dizzying array of diet variants touted to benefit inflammation and IBD, which has led to much confusion among patients, and even clinicians, over what is truly effective or not,” Berkeley Limketkai, MD, PhD, director of clinical research at the Center for Inflammatory Bowel Disease at the University of California, Los Angeles, said in an interview.

“Even experiences shared by well-meaning individuals might not be generalizable to others,” he said. “The lack of clarity on what is or is not effective motivated us to perform this systematic review and meta-analysis.”

The study was published online in Clinical Gastroenterology and Hepatology.
 

Analyzing diets

Some nutritional therapies, such as exclusive enteral nutrition, have good evidence to support their use in the treatment of IBD, Dr. Limketkai said. However, patients often find maintaining a liquid diet difficult, particularly over a long period of time, so clinicians and patients have been interested in solid food diets as a treatment for IBD.

In 2019, Dr. Limketkai and colleagues conducted a systematic review and meta-analysis of randomized controlled trials focused on solid food diets for IBD that was published with the Cochrane Collaboration. At that time, the data were considered sparse, and the certainty of evidence was very low or low. Since then, several high-quality trials have been published.

For this study, Dr. Limketkai and colleagues conducted an updated review of 36 studies and a meta-analysis of 27 studies that compared a solid food diet with a control diet in patients with Crohn’s disease or ulcerative colitis. The intervention arm had to involve a well-defined diet, not merely a “usual” diet.

Among the studies, 12 evaluated dietary interventions for inducing clinical remission in patients with active Crohn’s disease, and 639 patients were involved. Overall, a low–refined carbohydrate diet was superior to a high-carbohydrate diet or a low-fiber diet. In addition, a symptoms-guided diet, which sequentially eliminated foods that aggravated a patient’s symptoms, was superior to conventional nutrition advice. However, the studies had serious imprecisions and very low certainty of evidence.

Compared with respective controls, a highly restrictive organic diet, a low-microparticle diet, and a low-calcium diet were ineffective at inducing remission of Crohn’s disease. Studies focused on immunoglobulin G-based measures were also inconsistent.

When comparing diets touted to benefit patients with Crohn’s disease, the Specific Carbohydrate Diet was similar to the Mediterranean diet and the whole-food diet, though the certainty of evidence was low. Partial enteral nutrition was similar to exclusive enteral nutrition, though there was substantial statistical heterogeneity between studies and very low certainty of evidence.

For maintenance of Crohn’s disease remission, researchers evaluated 14 studies that included 1,211 patients with inactive disease. Partial enteral nutrition appeared to reduce the risk of relapse, although evidence certainty was very low. In contrast, reducing red meat or refined carbohydrates did not lower the risk of relapse.

“These findings seemingly contradict our belief that red meat and refined carbohydrates have proinflammatory effects, although there are other studies that appear to show inconsistent, weak, or no association between consumption of unprocessed red meat and disease,” Dr. Limketkai said. “The caveat is that our findings are based on weak evidence, which may change as more studies are performed over time.”

For induction of remission in ulcerative colitis, researchers evaluated three studies that included 124 participants with active disease. When compared with participants’ usual diet, there was no benefit from a diet that excluded symptom-provoking foods, fried foods, refined carbohydrates, additives, preservatives, most condiments, spices, and beverages other than boiled water. Other studies found no benefit from eliminating cow milk protein or gluten.

For maintenance of ulcerative colitis remission, they looked at four studies that included 101 patients with inactive disease. Overall, there was no benefit from a carrageenan-free diet, anti-inflammatory diet, or cow milk protein elimination diet.
 

Helping patients

Although the certainty of evidence remains very low or low for most dietary trials in IBD, the emerging data suggest that nutrition plays an important role in IBD management and should be considered in the overall treatment plan for patients, the study authors wrote.

“Patients continue to look for ways to control their IBD, particularly with diet. Providers continue to struggle with making evidence-based recommendations about dietary interventions for IBD. This systematic review is a useful tool for providers to advise their patients,” James D. Lewis, MD, associate director of the inflammatory bowel diseases program at the University of Pennsylvania, Philadelphia, said in an interview.

Dr. Lewis, who wasn’t involved with this study, has researched dietary interventions for IBD. He and his colleagues have found that reducing red meat does not lower the rate of Crohn’s disease flares and that the Mediterranean diet and Specific Carbohydrate Diet appear to be similar for inducing clinical remission.

Based on this review, partial enteral nutrition could be an option for patients with Crohn’s disease, Dr. Lewis said.

“Partial enteral nutrition is much easier than exclusive enteral nutrition for patients,” he said. “However, there remains uncertainty as to whether the solid food component of a partial enteral nutrition approach impacts outcomes.”

As more dietary studies become available, the certainty of evidence could improve and lead to better recommendations for patients, Dr. Limketkai and colleagues wrote. They are conducting several studies focused on the concept of precision nutrition.

“While certain diets may be helpful and effective for IBD, different diets work differently in different people. This concept is no different than the fact that different IBD medications work differently in different individuals,” Dr. Limketkai said. “However, given the current state of evidence for dietary interventions in IBD, we still have a long path of research ahead of us.”

The study received no funding. The study authors reported no conflicts of interest. Dr. Lewis reported no relevant disclosures.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
 

Influenza

Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.

RSV

In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.²

COVID-19

Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.

There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.

If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.³

With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.

Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
 

In summary

Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
 

Influenza

Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.

RSV

In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.²

COVID-19

Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.

There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.

If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.³

With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.

Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
 

In summary

Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

Cardiac injury caused by COVID-19 may be much less common than suggested previously, a new study has found.

The study examined cardiac MRI scans in 31 patients before and after having COVID-19 infection and found no new evidence of myocardial injury in the post-COVID scans relative to the pre-COVID scans.

“To the best of our knowledge this is the first cardiac MRI study to assess myocardial injury pre- and post-COVID-19,” the authors stated.

They say that while this study cannot rule out the possibility of rare events of COVID-19–induced myocardial injury, “the complete absence of de novo late gadolinium enhancement lesions after COVID-19 in this cohort indicates that outside special circumstances, COVID-19–induced myocardial injury may be much less common than suggested by previous studies.”

The study was published online in JACC: Cardiovascular Imaging.

Coauthor Till F. Althoff, MD, Cardiovascular Institute, Clínic–University Hospital Barcelona, said in an interview that previous reports have found a high rate of cardiac lesions in patients undergoing imaging after having had COVID-19 infection.

“In some reports, this has been as high as 80% of patients even though they have not had severe COVID disease. These reports have been interpreted as showing the majority of patients have some COVID-induced cardiac damage, which is an alarming message,” he commented.

However, he pointed out that the patients in these reports did not undergo a cardiac MRI scan before they had COVID-19 so it wasn’t known whether these cardiac lesions were present before infection or not.

To try and gain more accurate information, the current study examined cardiac MRI scans in the same patients before and after they had COVID-19.

The researchers, from an arrhythmia unit, made use of the fact that all their patients have cardiac MRI data, so they used their large registry of patients in whom cardiac MRI had been performed, and cross referenced this to a health care database to identify those patients who had confirmed COVID-19 after they obtaining a cardiac scan at the arrhythmia unit. They then conducted another cardiac MRI scan in the 31 patients identified a median of 5 months after their COVID-19 infection.

“These 31 patients had a cardiac MRI scan pre-COVID and post COVID using exactly the same scanner with identical sequences, so the scans were absolutely comparable,” Dr. Althoff noted.

Of these 31 patients, 7 had been hospitalized at the time of acute presentation with COVID-19, of whom 2 required intensive care. Most patients (29) had been symptomatic, but none reported cardiac symptoms.

Results showed that, on the post–COVID-19 scan, late gadolinium enhancement lesions indicative of residual myocardial injury were encountered in 15 of the 31 patients (48%), which the researchers said is in line with previous reports.

However, intraindividual comparison with the pre–COVID-19 cardiac MRI scans showed all these lesions were preexisting with identical localization, pattern, and transmural distribution, and thus not COVID-19 related.

Quantitative analyses, performed independently, detected no increase in the size of individual lesions nor in the global left ventricular late gadolinium enhancement extent.

Comparison of pre- and post COVID-19 imaging sequences did not show any differences in ventricular functional or structural parameters.

“While this study only has 31 patients, the fact that we are conducting intra-individual comparisons, which rules out bias, means that we don’t need a large number of patients for reliable results,” Dr. Althoff said.

“These types of lesions are normal to see. We know that individuals without cardiac disease have these types of lesions, and they are not necessarily an indication of any specific pathology. I was kind of surprised by the interpretation of previous data, which is why we did the current study,” he added.

Dr. Althoff acknowledged that some cardiac injury may have been seen if much larger numbers of patients had been included. “But I think we can say from this data that COVID-induced cardiac damage is much less of an issue than we may have previously thought,” he added.

He also noted that most of the patients in this study had mild COVID-19, so the results cannot be extrapolated to severe COVID-19 infection.

However, Dr. Althoff pointed out that all the patients already had atrial fibrillation, so would have been at higher risk of cardiac injury from COVID-19.

“These patients had preexisting cardiac risk factors, and thus they would have been more susceptible to both a more severe course of COVID and an increased risk of myocardial damage due to COVID. The fact that we don’t find any myocardial injury due to COVID in this group is even more reassuring. The general population will be at even lower risk,” he commented.

“I think we can say that, in COVID patients who do not have any cardiac symptoms, our study suggests that the incidence of cardiac injury is very low,” Dr. Althoff said.

“Even in patients with severe COVID and myocardial involvement reflected by increased troponin levels, I wouldn’t be sure that they have any residual cardiac injury. While it has been reported that cardiac lesions have been found in such patients, pre-COVID MRI scans were not available so we don’t know if they were there before,” he added.

“We do not know the true incidence of cardiac injury after COVID, but I think we can say from this data that it is definitely not anywhere near the 40%-50% or even greater that some of the previous reports have suggested,” he stated.

Dr. Althoff suggested that, based on these data, some of the recommendations based on previous reports such the need for follow-up cardiac scans and caution about partaking in sports again after COVID-19 infection, are probably not necessary.

“Our data suggest that these concerns are unfounded, and we need to step back a bit and stop alarming patients about the risk of cardiac damage after COVID,” he said. “Yes, if patients have cardiac symptoms during or after COVID infection they should get checked out, but I do not think we need to do a cardiac risk assessment in patients without cardiac symptoms in COVID.”

This work is supported in part by grants from Instituto de Salud Carlos III, the Spanish government, Madrid, and Fundació la Marató de TV3 in Catalonia. Dr. Althoff has received research grants for investigator-initiated trials from Biosense Webster.
