VANCOUVER – A new calculator that predicts short-term fracture risk at both 1 year and 3 years in patients on dialysis performed well in a study presented at the annual meeting of the American Society for Bone and Mineral Research.

The tool will soon be available on QxMD Calculate, which provides free decision-support tools for physicians, said presenter Andrea Cowan, MD, an assistant professor of medicine at the University of Western Ontario, London.

Dialysis patients have an approximately fivefold increased risk for fracture, Dr. Cowan noted, compared with the general population. However, treatments to prevent fracture risk are relatively limited and can have significant side effects. Therefore, “you really want to make sure that the person you’re targeting for treatment is actually going to be at a reasonable risk of fracture,” she said.

The Fracture Risk Assessment Tool (FRAX) is useful, but it estimates 10-year fracture risk, which is too long of a time frame to be useful for dialysis patients who experience a 50% 5-year mortality, according to Dr. Cowan. It does not take kidney failure or severe hyperparathyroidism into account, and it also requires information like bone mineral density, which poses an additional burden for a dialysis patient already undergoing multiple tests.

The new calculator could also be useful for research because it doesn’t rely on clinical data that might not be generally available, such as parental fracture, smoking status, or body mass index. “There’s a move towards things like pragmatic trials, which use more routinely collected data, have broader inclusion criteria, and are often more cost efficient to run. This calculator should be relatively easy to implement in trials using routinely collected data to perhaps define a subgroup of patients who may be at high risk of fracture without having to apply really cumbersome tools,” Dr. Cowan said.

The researchers included 11,599 patients between ages 40 and 89 years who were treated at a single center in Ontario between 2010 and 2017. The mean age was 66.18 years, 38.6% were women, 64.1% had diabetes, 11.9% had liver disease, and median time on dialysis was 0.81 years. The patients’ median parathyroid hormone level was 30 pmol/L.

At 3 years, the cumulative incidence of any fracture was 7.36% (95% confidence interval, 6.89-7.85), including 2.62% for hip fracture (95% CI, 2.34-2.93), 1.36% for spine fracture (95% CI, 1.16-1.59), 1.93% for wrist or forearm (95% CI, 1.69-2.20), and 2.15% for the pelvis (95% CI, 1.89-2.43). The incidence for all fractures at 1 year was 2.93 (95% CI, 2.62-3.26).

Variables associated with fracture risk included female sex (hazard ratio, 1.46; 95% CI, 1.27-1.67), a previous fracture more than 1 year in the past (HR, 1.65; 95% CI, 1.37-2.00), a fracture in the past year (HR, 3.63; 95% CI, 2.86-4.60), and proton pump inhibitor use (HR, 1.23; 95% CI, 1.04-1.45). After inclusion of vitamin D use, steroid use, time on dialysis, calcium levels, phosphate levels, presence of diabetes, rheumatoid arthritis, and chronic liver disease, the full model had an area under the curve of 77.7 at 1 year (95% CI, 73.3-84.4) and 69.9 at 3 years (95% CI, 68.0-72.2). For hip fracture, the model had an AUC of 80.1 at 1 year (95% CI, 77.0-83.5) and 71.9 at 3 years (95% CI, 70.1-74.2).

During the Q&A session, Dr. Cowan was asked how the tool could be implemented clinically. She said that it could have value in discussing fracture prediction and prevention with patients, but it could also increase fracture risk awareness among nephrologists. “I need to convince a lot of my colleagues because they’re focused on other things, so having this [calculator] I think is both good from a patient as well as a practitioner perspective. And the treatments that we have in people with end-stage renal disease are limited, so you want to know that you’re really targeting the high-risk person before you potentially put them on denosumab and increase the risk of severe hypercalcemia and things like that,” Dr. Cowan said.

The study points out the challenges of predicting fracture risk for specific populations, according to session comoderator Evelyn Hsieh, MD. She noted that the study needs follow-up. “I don’t think they had gotten to a validation [in a separate cohort] yet,” said Dr. Hsieh, an associate professor of medicine (rheumatology) and epidemiology (chronic diseases) at Yale University, New Haven, Conn.

Dr. Cowan and Dr. Hsieh have no relevant financial disclosures.

Hospitalized patients with both asthma and eosinophilic esophagitis (EoE) were a younger average age than those hospitalized with asthma alone, according to a new analysis of data from HCA Healthcare.

Not much work has been done on the overlap between the two conditions, both of which are believed to be driven by the action of both eosinophils and helper T cells, according to Linda Pham, DO, who presented the research at the annual meeting of the American College of Chest Physicians (CHEST).

“I have a colleague who is interested in GI and he’s really interested in EOE. We thought it would be nice to look at those populations of patients to see if there’s a correlation between them aside from just the atopic disease,” said Dr. Pham, who is an internal medicine resident at Riverside (Calif.) Community Hospital.

The findings underscore the need for assessing individual patient risk. “Having another concomitant disease like EoE, or maybe like atopic dermatitis, might cause you to have more severe [asthma] exacerbations causing you to go into the hospital more. I think if patients have more of these diseases, doctors can be more cognizant that they need to really be on top of treatment and make sure that [their patients] are aware of themselves so that if their symptoms exacerbate, they can go to the hospital and seek care,” said Dr. Pham.

The study was a retrospective analysis of 3,678,812 patients with asthma and 5,823 patients with both EoE and asthma. The data was drawn from 185 HCA hospitals, with records between 2016 and 2021.

The incidence of both asthma and asthma with EoE remained stable between 2016 and 2021. Dr. Pham pointed out that there are good methods to diagnose both conditions, which suggests that existing treatments are effective enough to be limiting the need for emergency treatment, according to Dr. Pham.

Among patients hospitalized with asthma alone, 72.55% were female, while 27.45% were male (P < .001). The numbers were much more evenly split among those with asthma and EoE, at 51.78% and 48.22%, respectively. The differing gender statistics aren’t easy to explain. “It’s not quite clear whether it’s because they just have more severe symptoms, or if it is other factors causing women to seek care more than their male counterparts. It could be personal biases, or it could be the asthma itself that is more severe in women,” said Dr. Pham.

When they broke down the analysis by sex, the researchers found that male EoE patients without asthma were a mean value of 5.517 years older than male EoE patients with asthma, and the mean difference was 5.480 years in female patients (P < .001 for both).

Although the direct cause of earlier hospitalization among patients with concomitant EoE and asthma is unclear, Dr. Pham speculated that the combination of atopic diseases may be leading to a stronger inflammatory response.

It remains to be seen if a similar relationship occurs with other atopic diseases, and future research could examine other factors. “I think it’d be good to look at not just age and gender, but BMI and occupation, things like that,” said Dr. Pham.

The study was of particular interest to Michelle Robertson, MD, who was in the audience. She is the director for clinical services at the Airborne Hazards and Burn Pits Center of Excellence at the New Jersey War-Related Illness and Injury Study Center. “We see a significant number of [veterans] who have been diagnosed with both asthma and eosinophilic esophagitis, and our thinking is that that is likely related to some of the military exposures: In particular, [what the] deployed veterans encountered in the Gulf War, [such as] the smoke from burn pits, sand and dust storms, and smoke from oil well fires. Our thinking is that the particulate matter, the PM 2.5, the very, very tiny particles, may be either sensitizing the lung area and/or esophagus and predisposing them to having those symptoms when they return home,” said Dr. Robertson, in an interview.

Particles in this size range may be able to bypass the protected areas of the nose and the lungs to reach the alveoli, where they could potentially interfere with the transfer of air between the lungs and the rest of the body, which could in turn lead to a variety of inflammatory conditions, according to Dr. Robertson.

She noted that particle exposure varies with a soldier’s wartime occupation, with higher exposures among mechanics and burn pit managers, for example. However, the highest levels of exposure do not predict later illness, which is a natural prompt for future research. “The second part of this whole pathophysiology is susceptibility. Is there something about those people that do get sick that makes them more susceptible than folks that don’t, even though they both have the same jobs?”

MILAN – The news about multiple sclerosis (MS) and child-bearing in women is largely good, a researcher told colleagues at the 9th Joint ECTRIMS-ACTRIMS Meeting. Evidence suggests that MS doesn’t disrupt fertility, pregnancy, birth, or lactation. However, there are still uncertainties about the timing of medical treatment for MS before, during, and after pregnancy.

Epidemiologist Emmanuelle Leray, PhD, of French School of Public Health in Rennes, urged neurologists to not be too eager to take women off medication – or too slow to put them back on it. “MS should not be undertreated due to a desire for pregnancy, as there are several options that are possible and compatible with pregnancy,” she said. As for after pregnancy, when women face a well-known high risk of MS rebound, “we can reasonably assume that women with active MS need to be advised to restart rapid, highly effective DMT [disease-modifying therapy] soon after delivery,” she said.

Women are more likely than men to develop MS, and they often do so during child-bearing years. Pregnancy among women with MS has become more common over the years: A 2018 Neurology study examined U.S. data from 2006 to 2014 and reported that the annual adjusted proportion of women with MS and pregnancy increased from 7.91% to 9.47%.

While it appears that women with MS get pregnant less often than the age-matched general population, that “doesn’t mean that fertility is impaired. It probably rather reflects the impact of an early diagnosis of MS on associated consequences regarding psychological and physical impact,” Dr. Leray said. “Regarding pregnancy outcomes, there is no evidence of an increased risk of prematurity or adverse neonatal outcomes. That’s why we can assume that multiple sclerosis will not impact the course of pregnancy and does not make a pregnancy at-risk.”

But some treatments may be harmful to the fetus, she said. Teriflunomide must be stopped before pregnancy. Natalizumab and fingolimod-siponimod raise the risk of rebound, and alternate drugs should be considered before pregnancy. However, anti–CD 20 drugs and cladribine “may be a relevant option because their use before pregnancy may provide effective disease control without exposing the fetus or the baby.”

Should women be on MS drugs at all during pregnancy, a period when MS typically wanes? “The recommendation is to discontinue disease-modifying therapy before conception,” Dr. Leray said. “However, we know now that some DMTs can be used safely during pregnancy, especially injectables.” Specifically, beta interferon and glatiramer acetate can be used safely during pregnancy, she said.

The biggest hurdle comes after pregnancy, when women face a high risk of MS rebound. The relapse rate has fallen in recent years from about 30% to 11%-14%, Dr. Leray said, possibly because of the rise of more effective treatment. But the risk, she said, is still significant.

What can clinicians do to avert relapse? According to Dr. Leray, research has failed to support several possible alternatives to DMTs – high-dose corticosteroids, intravenous immunoglobulin, and hormonal treatment. “There was no evidence of efficacy of any of these strategies, both in randomized clinical trials and in real-world studies.”

For now, it seems best to restart DMTs as soon as possible after delivery, Dr. Leray said. She urged colleagues to keep in mind that it takes about 3 months for DMTs to reach full efficacy – and research suggests the highest risk of relapse is during the first 3 months after delivery. “That has to be taken into account in the therapeutic strategy,” she said.

Dr. Leray reports consulting/lecture/travel grants from Biogen, Genzyme, MedDay, Merck, Novartis, and Roche.

Pregnancy among women with MS has become more common over the years: A 2018 Neurology study examined U.S. data from 2006 to 2014 and reported that the annual adjusted proportion of women with MS and pregnancy increased from 7.91% to 9.47%.

While it appears that women with MS get pregnant less often than the age-matched general population, that “doesn’t mean that fertility is impaired. It probably rather reflects the impact of an early diagnosis of MS on associated consequences regarding psychological and physical impact,” Dr. Leray said. “Regarding pregnancy outcomes, there is no evidence of an increased risk of prematurity or adverse neonatal outcomes. That’s why we can assume that multiple sclerosis will not impact the course of pregnancy and does not make a pregnancy at-risk.”

But some treatments may be harmful to the fetus, she said. Teriflunomide must be stopped before pregnancy. Natalizumab and fingolimod-siponimod raise the risk of rebound, and alternate drugs should be considered before pregnancy. However, anti–CD 20 drugs and cladribine “may be a relevant option because their use before pregnancy may provide effective disease control without exposing the fetus or the baby.”

Should women be on MS drugs at all during pregnancy, a period when MS typically wanes? “The recommendation is to discontinue disease-modifying therapy before conception,” Dr. Leray said. “However, we know now that some DMTs can be used safely during pregnancy, especially injectables.” Specifically, beta interferon and glatiramer acetate can be used safely during pregnancy, she said.

The biggest hurdle comes after pregnancy, when women face a high risk of MS rebound. The relapse rate has fallen in recent years from about 30% to 11%-14%, Dr. Leray said, possibly because of the rise of more effective treatment. But the risk, she said, is still significant.

What can clinicians do to avert relapse? According to Dr. Leray, research has failed to support several possible alternatives to DMTs – high-dose corticosteroids, intravenous immunoglobulin, and hormonal treatment. “There was no evidence of efficacy of any of these strategies, both in randomized clinical trials and in real-world studies.”

For now, it seems best to restart DMTs as soon as possible after delivery, Dr. Leray said. She urged colleagues to keep in mind that it takes about 3 months for DMTs to reach full efficacy – and research suggests the highest risk of relapse is during the first 3 months after delivery. “That has to be taken into account in the therapeutic strategy,” she said.

MILAN – The news about multiple sclerosis (MS) and child-bearing in women is largely good, a researcher told colleagues at the 9th Joint ECTRIMS-ACTRIMS Meeting. Evidence suggests that MS doesn’t disrupt fertility, pregnancy, birth, or lactation. However, there are still uncertainties about the timing of medical treatment for MS before, during, and after pregnancy.

Epidemiologist Emmanuelle Leray, PhD, of French School of Public Health in Rennes, urged neurologists to not be too eager to take women off medication – or too slow to put them back on it. “MS should not be undertreated due to a desire for pregnancy, as there are several options that are possible and compatible with pregnancy,” she said. As for after pregnancy, when women face a well-known high risk of MS rebound, “we can reasonably assume that women with active MS need to be advised to restart rapid, highly effective DMT [disease-modifying therapy] soon after delivery,” she said.

MADRID – Research presented at the European Society for Medical Oncology (ESMO) Annual Meeting 2023 underline the benefit of adding immunotherapy to chemotherapy in advanced or recurrent endometrial cancer, and question whether adding the PARP inhibitor olaparib to the chemo-immunotherapy combination could provide further benefit.

In the AtTEnd trial, presented on Oct. 21, more than 550 patients with advanced newly diagnosed or recurrent disease were randomized to the antiprogrammed death–ligand 1 (PD-L1) antibody atezolizumab (Tecentriq) or placebo plus chemotherapy followed by maintenance atezolizumab or placebo.

Adding immunotherapy to chemotherapy improved progression-free survival (PFS) among all-comers – 28.1% vs. 17% at 2 years. The PFS benefit was much more pronounced among patients with mismatch repair-deficient (dMMR) disease – 50.4% vs. 16% at 2 years. Mismatch repair-deficient disease patients receiving atezolizumab also demonstrated an early overall survival benefit, according to findings from the interim analysis.

In the DUO-E trial, presented during the same Oct. 21 session, nearly 720 patients with newly diagnosed advanced or recurrent endometrial cancer were randomized to one of three groups: Chemotherapy alone with maintenance placebo, chemotherapy plus durvalumab (Imfinzi) with maintenance durvalumab, or chemotherapy plus durvalumab with maintenance durvalumab and the PARP inhibitor olaparib.

The results, published simultaneously in the Journal of Clinical Oncology, showed that adding durvalumab to chemotherapy followed by maintenance durvalumab with or without olaparib led to a significant improvement in PFS, compared with chemotherapy alone. As in the AtTEnd trial, this PFS was also more pronounced in dMMR patients.

Overall, Andrés Cervantes, MD, PhD, from the University of Valencia, Spain, and president of ESMO, explained that this research marks “very positive data for women with gynecological cancers,” with immunotherapy now incorporated into the standard of care.

However, an expert questioned whether the DUO-E trial clearly demonstrated the benefit of adding olaparib to immuno- and chemotherapy and whether certain subsets of patients may be more likely to benefit from the PARP inhibitor.
 

Inside AtTEnd

A growing body of research has shown that single agent immunotherapy is effective in treating endometrial cancer, particularly in tumors with dMMR, and that immunotherapy and chemotherapy may have a synergistic effect.

David S. P. Tan, MD, PhD, National University Cancer Institute, Singapore, who was not involved in the studies, commented that “the molecular classification of endometrial cancer is now leading us to areas that we didn’t think before [were] possible.”

The rationale for combining immunotherapy with chemotherapy, Dr. Tan explained, is that “the cytotoxicity you get from chemotherapy is partly dependent on immune activity within the tumor, and so it makes sense” to combine them.

This approach was borne out by recent positive PFS results from the NRG-GY018 trial of pembrolizumab plus chemotherapy in advanced endometrial cancer as well as from the RUBY trial of dostarlimab in primary advanced or recurrent disease.

To further investigate this chemo-immunotherapy strategy, the AtTEnd team enrolled patients with newly diagnosed or recurrent stage III-IV disease who had received no prior systemic chemotherapy for recurrence within the previous 6 months.

Overall, 551 patients from 89 sites across 10 countries were randomized to standard first-line chemotherapy – carboplatin plus paclitaxel – with either atezolizumab or placebo, followed by maintenance atezolizumab or placebo, which continued until confirmed disease progression.

The median age in the intention-to-treat population was 64-67 years. Nearly 23% of patients had dMMR tumors, and 67.2% had recurrent disease.

The baseline characteristics were well balanced and distributed between arms in the dMMR and all-comers population, said Nicoletta Colombo, MD, University of Milan–Bicocca, European Institute of Oncology Istituto di Ricovero e Cura a Carattere Scientifico, Italy, who presented the findings at ESMO.

Over a median follow up of 26.2 months, Dr. Colombo and colleagues observed a statistically significant improvement in PFS in the dMMR arm in favor of atezolizumab (hazard ratio, 0.36; P = .0005). At 2 years, 50.4% of patients receiving the immunotherapy were progression-free, compared with 16.0% in the placebo arm.

In all-comers, the PFS improvement with atezolizumab was less pronounced but remained significant (HR, 0.74; P = .0219).

A secondary analysis revealed, among dMMR patients, atezolizumab was associated with an overall survival advantage over placebo (HR, 0.41), with 75% of patients still alive at 2 years vs. 54.2% in the placebo arm. Dr. Colombo also noted a “clear trend” for improved overall survival with atezolizumab as well (HR, 0.82; P = .0483), but no PFS or overall survival benefit was seen with atezolizumab in MMR proficient (pMMR) patients.

Dr. Colombo said the safety profile of atezolizumab plus chemotherapy was “manageable,” with no differences in the rates of “major side effects,” although there was an increase in the rate of treatment-related grade ≥ 3 adverse events in the atezolizumab group (25.8% vs. 14.1%).

Dr. Tan noted that the AtTEnd trial revealed comparable results to earlier trials in this space but underlined that the survival curves in the interim analysis revealed a “red zone” of dMMR patients who do not respond to the combination and in whom immunotherapy is “not sufficient.”

Alongside this, Dr. Tan flagged a “blue zone” of dMMR patients who plateaued in both PFS and overall survival after 2 years. The question for these patients at this point is whether they need to continue immunotherapy beyond 24 months, he said.

But overall, Dr. Tan noted, the AtTEnd data “continue to validate practice-changing therapy for dMMR endometrial cancer patients” with immunotherapy plus chemotherapy, with the lack of benefit in pMMR disease underscoring an “unmet medical need.”
 

Inside DUO-E

The burning question, however, was whether adding a PARP inhibitor to immunotherapy and chemotherapy would boost the survival outcomes further.

The DUO-E trial involved patients with newly diagnosed stage III/IV or recurrent endometrial cancer who had not received systematic therapy for advanced disease and were naive to both PARP inhibitors and immune-mediated therapy.

Overall, 718 patients were randomized to one of three arms: Chemotherapy alone followed by maintenance placebo, chemotherapy plus durvalumab with maintenance durvalumab, or chemotherapy plus durvalumab with maintenance durvalumab plus olaparib.

Maintenance was continued until disease progression or unacceptable toxicity, or the patients met another discontinuation criteria.

About half of patients were newly diagnosed, half had recurrent disease, and approximately one-fifth had dMMR disease, said Shannon Westin, MD, from the University of Texas MD Anderson Cancer Center, Houston, who presented the findings.

Compared with placebo plus chemotherapy, patients in both the durvalumab alone and durvalumab plus olaparib arms experienced a significant improvement in PFS (HR, 0.71; P = .003; and HR, 0.55; P < .0001, respectively).

This effect was amplified in dMMR patients with durvalumab (HR, 0.42) as well as with durvalumab plus olaparib (HR, 0.41).

In pMMR patients, PFS benefit was stronger in the durvalumab-olaparib arm vs. durvalumab (HR, 0.57 vs. 0.77).

Although the overall survival analysis remains exploratory, Dr. Westin noted a trend toward better overall survival in the two treatment arms vs. placebo (HR, 0.77 with durvalumab, and HR, 0.59 with durvalumab plus olaparib).

However, adding olaparib to the equation increased the rate of grade ≥ 3 adverse events – 67.2% vs. 54.9% with durvalumab and 56.4% with chemotherapy alone in the overall analysis. The addition of olaparib also led to treatment discontinuation in 24.4% of patients vs. 20.9% in the durvalumab arm and 18.6% in the chemotherapy alone arm.

Domenica Lorusso, MD, PhD, who was not involved in the study, commented that the marginal PFS benefit of adding olaparib in DUO-E is “not surprising” because the bar set by immunotherapy is “so high in this population that it’s very difficult” to go any higher.

But the results in pMMR patients reveal “a clear additional benefit” to olaparib, said Dr. Lorusso, from Fondazione IRCCS Istituto Nazionale dei Tumori, Milan.

“The main limitation of the trial,” she continued, “is that it was not powered to make a formal comparison between the two experimental arms.”

So, what then is the added benefit of olaparib? “Unfortunately, that remains an unanswered question,” Dr. Lorusso said.

However, adding olaparib to the equation increased the rate of grade ≥ 3 adverse events – 67.2% vs. 54.9% with durvalumab and 56.4% with chemotherapy alone in the overall analysis. The addition of olaparib also led to treatment discontinuation in 24.4% of patients vs. 20.9% in the durvalumab arm and 18.6% in the chemotherapy alone arm.

Domenica Lorusso, MD, PhD, who was not involved in the study, commented that the marginal PFS benefit of adding olaparib in DUO-E is “not surprising” because the bar set by immunotherapy is “so high in this population that it’s very difficult” to go any higher.

But the results in pMMR patients reveal “a clear additional benefit” to olaparib, said Dr. Lorusso, from Fondazione IRCCS Istituto Nazionale dei Tumori, Milan.

“The main limitation of the trial,” she continued, “is that it was not powered to make a formal comparison between the two experimental arms.”

So, what then is the added benefit of olaparib? “Unfortunately, that remains an unanswered question,” Dr. Lorusso said.

DALLAS – Researchers identified behavioral, psychological, and environmental predictors of continued weight loss maintenance vs. weight regain in a large cohort of members of WeightWatchers who had successful long-term weight loss.

On average, the participants had lost 25.5 kg (56 lb) and kept it off for 3.5 years, when they entered the 1-year study.

At study entry and 1 year later, the participants replied to several questionnaires that asked about predictors of weight loss maintenance.

Compared with people who gained weight over the 1-year study, those who maintained their weight within 2.3 kg (5 lb) reported more consistent monitoring of their diet and weight and greater acceptance of uncomfortable food cravings.

They also had reduced disinhibition (tendency to overeat) when faced with food cues, as well as less pain and a more positive body image “at any weight, shape, or size,” Suzanne Phelan, MD, PhD, reported.

Dr. Phelan, from the department of kinesiology and public health, California Polytechnic State University, San Luis Obispo, presented the study in an Obesity symposium at the annual meeting of the Obesity Society, and it was simultaneously published in the journal. The study was selected as one of five top papers submitted to the journal to coincide with the meeting.

Future interventions to prevent weight regain should target overeating in response to internal and external food cues and declines in self-monitoring and body image, Dr. Phelan said.

The study aimed to identify behaviors that might predict who might “beat the odds” and sustain long-term weight loss, she said in an interview.

The findings suggest that the people who maintained their weight loss had developed skills to help them cope with cravings and not respond by eating, she said. Continued self-monitoring and body acceptance and appreciation (all body sizes are beautiful) were key elements of successful weight-loss maintenance.
 

No antiobesity drugs or surgery; don’t forget behavioral stuff

Importantly, although 43% of the study participants regained more than five pounds during this 1-year study, they still remained at 18% below their starting weight, “indicating that they were largely successful at weight loss,” Dr. Phelan said.

Michael D. Jensen, MD, editor-in-chief of Obesity, echoed this.

The researchers “did find some weak predictors of success,” said Dr. Jensen, from Mayo Clinic, Rochester, Minn. “But perhaps as important,” he said, “was that at the end of the trial, even those who had regained some slight weight still had 18% weight loss – which is not trivial – after, on average, 4.5 years with a standard commercial weight management program.

“At every talk I go to here,” the message is, “Let’s stampede towards use of the drugs and skip diet and exercise and behavioral stuff,” he observed. “I would argue,” he said, “that when it works, it works really well, and it’s free. So this idea that we shouldn’t even try it, because we know it’s going to fail, is wrong.

“If you have the right group, they have a decent chance of having a sufficiently good response that you don’t have to give the medications and you don’t have to send them for bariatric surgery.

“Once you learn from these programs what to do, you’re not paying $1,000 a month for a drug and you haven’t had bariatric surgery,” Dr. Jensen noted. “Their 3 years of follow-up of WeightWatchers cost less than 1 month worth of one of these [antiobesity medications].”

The predictive findings were like ‘”icing on the cake,” he said. Anybody can find five people who’ve done well with therapy, but this study was in more than 2,800 people who did well with a commercial program that is not expensive.
 

Study design and findings

Between 2019 and 2020, WeightWatchers invited adult members who had maintained weight loss of at least 9.1 kg (20 lb) for at least 1 year to participate in this study.

Of 7,025 participants who entered the study, 4,004 individuals (57%) who did not complete the 1-year questionnaires and others with implausible weight were excluded, leaving a final sample of 2,843 participants.

Most participants were women (92%), non-Hispanic White (95%), married (92%), and college educated. They had a mean age of 56 years.

On average, the participants had a body mass index (BMI) of 35.9 kg/m² (grade 2 obesity) at the start of the WeightWatchers program and a BMI of 26.7 when they entered the current study.

At the 1-year follow-up, 57% of the participants had maintained the same weight (within 2.3 kg) as when they enrolled in the study, and 43% had gained ≥ 2.3 kg.

On average, the weight-loss maintainers had gained 0.4 kg (0.88 lb). The weight gainers had gained 7.2 kg (15.9 lb) but were still 19.1 kg (42.1 lb) below the weight they had when they started the WeightWatchers program.

At baseline, compared with the weight gainers, the weight-loss maintainers were on average older (58 vs. 52 years), had a lower initial BMI (26 vs. 28), and had longer duration of weight loss maintenance (4 vs. 3 years).

At 1 year, those who had maintained their weight loss had greater self-monitoring, psychological coping, physical activity strategies, dietary choice strategies, and eating and physical activity habits, and they had less eating initiation in the absence of hunger.

They also had less disinhibition, more willingness to ignore cravings and accept food urges, more future orientation, more mindfulness, more positive body image and body satisfaction, better general health and mental health, and less bodily pain.

This research was supported by a grant to Dr. Phelan from WeightWatchers (WW) International, and three study authors are employees and shareholders of the company. Dr. Jensen discloses consulting for Biohaven Pharmaceuticals and for Seattle Gummy Co.

MILAN – A tool kit combining a wearable device with automated algorithms allows for the passive monitoring of disease parameters in people with multiple sclerosis (MS) and may even be able to predict the course of the disease, suggests a pilot study.

Twenty patients were enrolled, only half of whom correctly completed all of the assessments and wore the included smartwatch regularly. Importantly, the data reported back for analysis was in line with expectations, and the patient feedback was positive.

The tool kit “seems feasible and usable to remotely monitor multiple domains of health status in people with multiple sclerosis,” conclude Ludovico Pedullà, PhD, Italian Multiple Sclerosis Foundation, Genoa, and colleagues.

Further analysis of the dataset, including the artificial intelligence and machine-learning algorithms, may allow the prediction of “relevant changes throughout the course of multiple sclerosis” and anticipate the need for therapeutic interventions.

The findings were presented at the 9th Joint ECTRIMS-ACTRIMS meeting.
 

Leveraging big data to improve outcomes

The authors note that the primary aim of the pan-European ALAMEDA project is to leverage “big data” through artificial intelligence and machine learning to provide “clinically actionable information” on patients with brain disorders that “complements medical recommendations” and thus improves treatment.

For the current pilot study, the researchers developed an integrated platform to collect patient-centered data from wearables and mobile devices using digital patient-reported outcomes (ePROs), with the aim of testing the resulting tool kit’s feasibility and usability in people with MS.

Dr. Pedullà said that they wanted to have “passive monitoring” of patients over the course of their daily lives and therefore searched for the best devices and the most relevant patient reported outcomes as well as used “innovative algorithms” to analyze the data to try to predict the disease course.

To reduce dropouts and increase adherence to the tool kit, they described the project to patients with MS and asked for their feedback to determine whether what they had designed was feasible from the patient perspective, Dr. Pedullà said.

This led to some changes in the way data were collected, and the team developed a social network channel so patients would be able to ask for support and stay engaged in the study.
 

Feasible with high levels of confidence

Twenty people with relapsing-remitting MS were enrolled, of whom 14 were women. The mean age was 37.8 years, and the mean disease duration was 9.1 years. The mean Expanded Disability Status Scale was 2.2.

The participants were asked to use the tool kit for 1 year, with half reaching the 6-month milestone. Participants correctly completed 53% of the scheduled ePROs and regularly wore the smartwatch without reporting discomfort.

The team reports that the data from the tool kit “are in line with those reported in the literature.”

It showed that participants took an average of 8,415 steps per day and completed 9.8 minutes of vigorous activity and 14.5 minutes of moderate activity daily. Daily sedentary minutes were 705.1.

Patients had a mean Perceived Deficit Questionnaire score of 25.2, a Beck Anxiety Inventory score of 17.3, a score on the 12-Item Multiple Sclerosis Walking Scale of 37.2, and an arm function on the Multiple Sclerosis Questionnaire of 47.4.

The mean Modified Fatigue Impact Scale score was 18.5, and the Pittsburgh Sleep Quality Index score was 25.2. The System Usability Scale revealed “high levels of confidence” with the tool kit, the team says, as well as “very high” intention of using it in the future.

Dr. Pedullà said that the researchers now want to evaluate the feasibility of the tool kit further by analyzing the adherence and usability data and targeting it to the patients who are most likely to use it.

They also want to determine not only whether the use of wearables in this way can predict relapse in multiple sclerosis but also disease progression, particularly as the current definitions are evolving.
 

Reducing daily step count

Approached for comment, Riley M. Bove, MD, MSc, Assistant Professor, UCSF Weill Institute for Neurosciences, San Francisco, said that the study is “very interesting and in line with what has been previously published.”

She pointed to a recent study that she co-authored, in which remote monitoring via a continuous step counter revealed that a decreasing average daily step count was associated with the worsening of standard ambulatory measures.

“There are nice benefits of an integrated platform” such as what was used in the current study, Dr. Bove noted, adding that it is “even better if it can also send the data to clinicians.”

The ALAMEDA project has received funding from the European Union’s Horizon 2020 research and innovation program. No relevant financial relationships declared.

GLASGOW – ChatGPT failed to pass the U.K.’s National Primary Care examinations in a new study, highlighting how artificial intelligence (AI) does not necessarily match human perceptions of medical complexity.

ChatGPT also provided novel explanations – it frequently “hallucinates” – by describing inaccurate information as if they were facts, according to Shathar Mahmood, BA, a fifth-year medical student at the University of Cambridge, England, who presented the findings at the annual meeting of the Royal College of General Practitioners. The study was published in JMIR Medical Education earlier this year.

“Artificial intelligence has generated impressive results across medicine, and with the release of ChatGPT there is now discussion about these large language models taking over clinicians’ jobs,” Arun James Thirunavukarasu, MB BChir, of the University of Oxford, England, and Oxford University Hospitals NHS Foundation Trust, who is the lead author of the study, told this news organization.

Performance of AI on medical school examinations has prompted much of this discussion, often because performance does not reflect real-world clinical practice, he said. “We used the Applied Knowledge Test instead, and this allowed us to explore the potential and pitfalls of deploying large language models in primary care and to explore what further development of medical large language model applications is required.”

The researchers investigated the strengths and weaknesses of ChatGPT in primary care using the Membership of the Royal College of General Practitioners Applied Knowledge Test. The computer-based, multiple-choice assessment is part of the U.K.’s specialty training to become a general practitioner (GP). It tests knowledge behind general practice within the context of the United Kingdom’s National Health Service.

The researchers entered a series of 674 questions into ChatGPT on two occasions, or “runs.” “By putting the questions into two separate dialogues, we hoped to avoid the influence of one dialogue on the other,” Ms. Mahmood said. To validate that the answers were correct, the ChatGPT responses were compared with the answers provided by the GP self-test and past articles.

Overall performance of the algorithm was good across both runs (59.94% and 60.39%); 83.23% of questions produced the same answer on both runs.

But 17% of the answers didn’t match, Ms. Mahmood reported, a statistically significant difference. “And the overall performance of ChatGPT was 10% lower than the average RCGP pass mark in the last few years, which informs one of our conclusions about it not being very precise at expert level recall and decision-making,” she said.

Also, a small percentage of questions (1.48% and 2.25% in each run) produced an uncertain answer or there was no answer.
 

Say what?

Novel explanations were generated upon running a question through ChatGPT that then provided an extended answer, Ms. Mahmood said. When the accuracy of the extended answers was checked against the correct answers, no correlation was found. “ChatGPT can hallucinate answers, and there’s no way a nonexpert reading this could know it is incorrect,” she said.

Regarding the application of ChatGPT and similar algorithms to clinical practice, Ms. Mahmood was clear. “As they stand, [AI systems] will not be able to replace the health care professional workforce, in primary care at least,” she said. “I think larger and more medically specific datasets are required to improve their outputs in this field.”

Sandip Pramanik, MBcHB, a GP in Watford, Hertfordshire, England, said the study “clearly showed ChatGPT’s struggle to deal with the complexity of the exam questions that is based on the primary care system. In essence, this in indicative of the human factors involved in decision-making in primary care.”

The applied knowledge test is designed to test the knowledge required to be a generalist in the primary care setting, and as such, there are lots of nuances reflecting this within the questions, Dr. Pramanik said.

“ChatGPT may look at these in a more black and white way, whereas the generalist needs to be reflective of the complexities involved and the different possibilities that can present rather than take a binary ‘yes’ or ‘no’ stance,” he said. “In fact, this highlights a lot about the nature of general practice in managing uncertainty, and this is reflected in the questions asked in the exam,” he remarked. He noted, “Being a generalist is about factoring in human emotion and human perception as well as knowledge.”

Ms. Mahmood, Dr. Thirunavukarasu, and Dr. Pramanik have disclosed no relevant financial relationships.

Playing chess or other board games slows cognitive decline and improves quality of life in older patients, results of a new systematic review suggest.
 

“For patients who are elderly and suffer from social isolation and mild cognitive issues, I would definitely recommend board games,” study investigator Frederico Emanuele Pozzi, MD, a neurology resident at Fondazione IRCCS San Gerardo dei Tintori in Monza, Italy, told this news organization.

The findings were presented at the virtual XXVI World Congress of Neurology (WCN).

After searching the published literature, Dr. Pozzi and his colleagues selected 15 studies for the review. The studies assessed the impact of board games on older individuals at risk of or with cognitive impairment, or those with mild cognitive impairment (MCI) at any age.

The studies included different board games including chess, Mah-jongg, and Go, a two-player game popular in China, Japan, and Korea that involves moving board pieces to surround and capture as much territory as possible.

Most interventions lasted about an hour and were held once or twice per week for 3-4 months.
 

Which games are best?

Researchers found that board games improved cognitive function, as measured by improved scores on the Montreal Cognitive Assessment (P = .003) and Mini-Mental State Examination (P = .02).

Playing Go was linked with improved working memory, as measured by the Trail Making Test-A. Those who played Mah-jongg reported improved executive functioning and a temporary decrease in depressive symptoms. And chess players reported improved quality of life on the World Health Organization Quality of Life scale from playing chess (P < .00001).

In general, cognition improved across different populations. For example, some studies looked at unimpaired elderly while others looked at MCI, said Dr. Pozzi.

Playing board games in a social context appeared to be especially good at boosting brain power. One Japanese study included a control group that just did tai chi, a group that did Go alone on tablets, and another group that did Go in groups. Both Go groups improved cognitively, but participants who played together improved the most.

The results also seemed to suggest that Go and chess have different biological effects. “For example, Go increased [brain-derived neurotrophic factor] (BDNF) levels and metabolism in areas key for cognition like the middle temporal gyrus,” Dr. Pozzi said.

He noted that the methodology of the studies was generally “not bad,” although in some cases the analyses were per protocol and in others intention-to-treat. Outcomes varied across studies, there were a lot of dropouts, and some were not randomized, meaning reverse causality can’t be ruled out.

Dr. Pozzi has started a randomized controlled trial at a Go and chess club in Italy. He’s enrolling patients aged 60 and over with subjective cognitive decline or MCI and separating participants into a control group, a group that plays chess, another that plays Go, and another that plays both Go and chess.

In addition to the standard cognitive tests, and measures of depression and quality of life, Dr. Pozzi aims to assess cognitive reserve and is in the process of validating a questionnaire that will look at leisure activities and lifestyle.
 

Social and cognitive value

Commenting on the research for this news organization, Vladimir Hachinski, MD, a professor of clinical neurological sciences at Western University in London, Ont., said the results make sense.

Playing a board game involves concentration, strategy, and intermittent rewards – all of which are good for the brain and may involve the prefrontal cortex, he noted. Board games are also typically timed, which involves brain speed processing, and they have a winner and loser so emotions can run high, which also affects the brain, Dr. Hachinski added.

There may also be social value in playing a board game with someone else, added Dr. Hachinski.

“It’s encouraging that people can improve what they’re doing, and the longer they’re at it, the more of the brain they use,” he said. “There might be a long-term effect because players are building up networks.”

But Dr. Hachinski cautioned that playing a lot of chess does not necessarily make you a better thinker, just as learning to play one instrument doesn’t mean you can automatically play others.

“Learning one skill will translate only partially to another, and only if it’s related,” he said. “It increases cognition in the area you’re practicing in, but it doesn’t spread to other areas.”

Dr. Pozzi and Dr. Hachinski report no relevant financial relationships.

VANCOUVER – With treatment with a bisphosphonate following sequential use of teriparatide (Forteo) and denosumab (Prolia) for premenopausal women with idiopathic osteoporosis, bone mineral density (BMD) was maintained over the first year following denosumab cessation, according to results from a small, nonrandomized extension of a phase 2 study.

Bisphosphonates are recommended for patients after they have completed a course of denosumab because cessation of the bone resorption blocker is known to increase bone turnover markers, decrease BMD, and raise the risk of vertebral fractures. Although there is evidence to support this treatment sequence for postmenopausal women, there was no evidence regarding premenopausal women with idiopathic osteoporosis, said Adi Cohen, MD, who presented the results of the study at the annual meeting of the American Society for Bone and Mineral Research.

In the extension study, neither length of treatment with denosumab nor transition to menopause affected BMD results. Weekly doses of alendronate (ALN) better suppressed C-terminal telopeptide (CTX) than did zoledronic acid (ZOL) and led to better maintenance of BMD than did a single dose of ZOL. The researchers suggested that single-dose ZOL may not prevent bone loss for an entire year.

It is too early to call the results practice changing, said Dr. Cohen, professor of medicine and endocrinology at Columbia University Irving Medical Center, New York, but she noted, “It’s important just to provide information about how sequences of osteoporosis medications might be used in a rare but certainly understudied group of premenopausal women with osteoporosis who need treatment, and these data hopefully will help make some treatment decisions.”

In the early 2000s, researchers initially believed that premenopausal women with low BMD had experienced some kind of temporary event and that they would likely improve on their own over time. “I think we now recognize that whatever it is that causes this is an ongoing issue and that this is a problem they’re going to have to deal with for the rest of their lives. This is something that they have to stay on top of,” said coauthor Elizabeth Shane, MD, who is a professor of medicine at CUIMC.

However, there are no practice guidelines for the management of osteoporosis in premenopausal women, according to Dr. Shane. She noted that there is controversy as to whether to treat women with low bone density who do not have a history of fractures. “I think that there’s pretty much agreement that anybody who has a lot of fractures has an early-onset form of osteoporosis. The controversy is what to do about the person who just has a low bone density and hasn’t yet fractured and what is the utility of trying to treat them at that point and perhaps prevent a fracture. I don’t think we have enough data to address that,” Dr. Shane said.

Still, the research has provided some clarity in her own practice. “I think if somebody would come to my office who had very low bone density, I would probably treat them. If they have fractures, I would definitely treat them. I think that our work has provided a framework for people to approach that,” she said.

The study was an extension of a sequential treatment approach that began with 2 years of teriparatide (20 mcg daily) followed by an extension study of 2–3 years of treatment with denosumab (60 mg every 6 months). Seven months after the last dose of denosumab, patients underwent 1 year of treatment with ALN (70 mg weekly; n = 18) or a single dose of ZOL (5 mg IV; n = 6), according to patient choice.

The original phase 2 study started with 41 women. At 24 months, teriparatide treatment led to BMD increases of 13% in the lumbar spine (LS), 5% in the total hip (TH), and 5% in the femoral neck (FN). There was a 2% decline in BMD in the forearm (distal radius [DR]). A group of 32 of the women participated in an extension study and took denosumab for 12 months. Of those patients, 29 continued to take it for another 12 months. At 12 months, BMD increased 5% in the LS, 3% in the TH, 3% in the FN, and 1% in the DR (P < .05 for all). At 24 months, BMD rose by 22%, 10%, and 10% at the first three of those locations. BMD in the DR remained stable, compared with the baseline after taking teriparatide.

The bisphosphonate phase of the extension study included 24 women (mean age, 43 years). The mean body mass index of the patients was 23.0 kg/m². The patients had experienced a mean of 3.0 fractures in adulthood, and 38% of patients had a history of vertebral fracture.

Over 12 months of follow-up, the researchers found no statistically significant difference in BMD in the LS, TH, or FN, compared with bisphosphonate extension baseline. There was also no statistically significant change in serum CTX. There was evidence that, among patients with higher rates of bone turnover, there were higher rates of LS and FN bone loss during bisphosphonate treatment.

Among patients taking ZOL, at 12 months there was a statistically significant rise in CTX levels, but not among patients taking ALN. There were no new vertebral fractures among any participants during the bisphosphonate extension period.

The results represent critical data for an understudied population, according to Yumie Rhee, MD, PhD, who was comoderator of the session in which the study was presented. “They are showing that by using a bisphosphonate [patients] have this just slight decrease, but within error, so it’s maintaining the BMD, at least. I think it’s very important. It will be fascinating to see next year’s follow-up,” said Dr. Rhee, a professor of endocrinology at Yonsei University College of Medicine in Seoul, South Korea. “The problem with premenopausal osteoporosis is that we don’t have good evidence. Even though this study is very small, we’re just following that data, all of us.”

Comoderator Maria Zanchetta, MD, a professor of osteology at the Institute of Diagnostics and Metabolic Research, Universidad del Salvador, Buenos Aires, agreed. “We know what to do when we stop denosumab in postmenopausal women. We didn’t have any work about what to do when we stopped in premenopausal women. You can think that probably it’s going to be the same, but this is the first time you have the evidence that if you give bisphosphonate, you will maintain BMD.”

Limitations to the study include its small size and the lack of a placebo-treated control group. In addition, the bisphosphonate extension was not randomized.

The studies were funded by the U.S. Food and Drug Administration and Amgen. Dr. Cohen and Dr. Shane received research funding from Amgen. Dr. Rhee and Dr. Zanchetta have disclosed no relevant financial relationships.

This is something that they have to stay on top of,” said coauthor Elizabeth Shane, MD, who is a professor of medicine at CUIMC.

However, there are no practice guidelines for the management of osteoporosis in premenopausal women, according to Dr. Shane. She noted that there is controversy as to whether to treat women with low bone density who do not have a history of fractures. “I think that there’s pretty much agreement that anybody who has a lot of fractures has an early-onset form of osteoporosis. The controversy is what to do about the person who just has a low bone density and hasn’t yet fractured and what is the utility of trying to treat them at that point and perhaps prevent a fracture. I don’t think we have enough data to address that,” Dr. Shane said.

Still, the research has provided some clarity in her own practice. “I think if somebody would come to my office who had very low bone density, I would probably treat them. If they have fractures, I would definitely treat them. I think that our work has provided a framework for people to approach that,” she said.

The study was an extension of a sequential treatment approach that began with 2 years of teriparatide (20 mcg daily) followed by an extension study of 2–3 years of treatment with denosumab (60 mg every 6 months). Seven months after the last dose of denosumab, patients underwent 1 year of treatment with ALN (70 mg weekly; n = 18) or a single dose of ZOL (5 mg IV; n = 6), according to patient choice.

The original phase 2 study started with 41 women. At 24 months, teriparatide treatment led to BMD increases of 13% in the lumbar spine (LS), 5% in the total hip (TH), and 5% in the femoral neck (FN). There was a 2% decline in BMD in the forearm (distal radius [DR]). A group of 32 of the women participated in an extension study and took denosumab for 12 months. Of those patients, 29 continued to take it for another 12 months. At 12 months, BMD increased 5% in the LS, 3% in the TH, 3% in the FN, and 1% in the DR (P < .05 for all). At 24 months, BMD rose by 22%, 10%, and 10% at the first three of those locations. BMD in the DR remained stable, compared with the baseline after taking teriparatide.

The bisphosphonate phase of the extension study included 24 women (mean age, 43 years). The mean body mass index of the patients was 23.0 kg/m². The patients had experienced a mean of 3.0 fractures in adulthood, and 38% of patients had a history of vertebral fracture.

Over 12 months of follow-up, the researchers found no statistically significant difference in BMD in the LS, TH, or FN, compared with bisphosphonate extension baseline. There was also no statistically significant change in serum CTX. There was evidence that, among patients with higher rates of bone turnover, there were higher rates of LS and FN bone loss during bisphosphonate treatment.

Among patients taking ZOL, at 12 months there was a statistically significant rise in CTX levels, but not among patients taking ALN. There were no new vertebral fractures among any participants during the bisphosphonate extension period.

The results represent critical data for an understudied population, according to Yumie Rhee, MD, PhD, who was comoderator of the session in which the study was presented. “They are showing that by using a bisphosphonate [patients] have this just slight decrease, but within error, so it’s maintaining the BMD, at least. I think it’s very important. It will be fascinating to see next year’s follow-up,” said Dr. Rhee, a professor of endocrinology at Yonsei University College of Medicine in Seoul, South Korea. “The problem with premenopausal osteoporosis is that we don’t have good evidence. Even though this study is very small, we’re just following that data, all of us.”

Comoderator Maria Zanchetta, MD, a professor of osteology at the Institute of Diagnostics and Metabolic Research, Universidad del Salvador, Buenos Aires, agreed. “We know what to do when we stop denosumab in postmenopausal women. We didn’t have any work about what to do when we stopped in premenopausal women. You can think that probably it’s going to be the same, but this is the first time you have the evidence that if you give bisphosphonate, you will maintain BMD.”

Limitations to the study include its small size and the lack of a placebo-treated control group. In addition, the bisphosphonate extension was not randomized.

The studies were funded by the U.S. Food and Drug Administration and Amgen. Dr. Cohen and Dr. Shane received research funding from Amgen. Dr. Rhee and Dr. Zanchetta have disclosed no relevant financial relationships.

VANCOUVER – With treatment with a bisphosphonate following sequential use of teriparatide (Forteo) and denosumab (Prolia) for premenopausal women with idiopathic osteoporosis, bone mineral density (BMD) was maintained over the first year following denosumab cessation, according to results from a small, nonrandomized extension of a phase 2 study.

Bisphosphonates are recommended for patients after they have completed a course of denosumab because cessation of the bone resorption blocker is known to increase bone turnover markers, decrease BMD, and raise the risk of vertebral fractures. Although there is evidence to support this treatment sequence for postmenopausal women, there was no evidence regarding premenopausal women with idiopathic osteoporosis, said Adi Cohen, MD, who presented the results of the study at the annual meeting of the American Society for Bone and Mineral Research.

In the extension study, neither length of treatment with denosumab nor transition to menopause affected BMD results. Weekly doses of alendronate (ALN) better suppressed C-terminal telopeptide (CTX) than did zoledronic acid (ZOL) and led to better maintenance of BMD than did a single dose of ZOL. The researchers suggested that single-dose ZOL may not prevent bone loss for an entire year.

It is too early to call the results practice changing, said Dr. Cohen, professor of medicine and endocrinology at Columbia University Irving Medical Center, New York, but she noted, “It’s important just to provide information about how sequences of osteoporosis medications might be used in a rare but certainly understudied group of premenopausal women with osteoporosis who need treatment, and these data hopefully will help make some treatment decisions.”

HONOLULU – The diversity of species in the sputum of patients undergoing therapy for nontuberculosis mycobacterial pulmonary disease (NTM-PD) could be a marker for treatment efficacy, authors of a small prospective study suggest.

Neil Osterweil/MDedge

Among 14 patients treated for NTM-PD, 7 of whom had treatment-refractory disease and 7 of whom had microbiological cures after antibiotic therapy, the diversity of the microbiome in sputum was greater for those patients who were cured, indicating that the variety of species found in sputum during treatment could help clinicians evaluate the efficacy of therapy and guide patient management, said Noeul Kang, MD, PhD, from Samsung Medical Center in Seoul, South Korea.

“What we found was that in NTM-PD patients, the sputum of the patients who remained in long-time stabilization without recurrence exhibited higher microbiome diversity than that of treatment-refractory patients, and several genera were identified in the samples of the cured group. We hope to do more research on this, and we are planning to compare the patients who have never been treated with those who respond to treatment,” she said at the annual meeting of the American College of Chest Physicians (CHEST).
 

NTM-PD on the rise

The incidence and prevalence of NTM-PD in both South Korea and the United States have been rising steadily since 2007, with the highest incidence occurring among those 65 and older.

“NTM-PD is becoming a global burden,” Dr. Kang said.

Across the world the most commonly occurring organisms in NTM-PD patients are Mycobacterium avium complex (MAC), with other mycobacteria species varying in frequency by region.

Outcomes of treatment differ according to the etiologic organism, with M. avium complex infections being successfully treated in about 60% of patients, compared with 70% of patients’ infections with the M. abscessus massiliense, and 30%-40% of infections yielding to antibiotics in patients with M. abscessus abscessus, Dr. Kang said.

To compare the characteristics of the sputum microbiota of NTM-PD patients based on their treatment outcomes, Dr. Kang and colleagues looked at sputum from all patients with NTM-PD who agreed to provide samples at their center from 2018 through 2022.

After excluding those who did not receive antibiotics, those who were on treatment but did not have refractory disease, and those who were lost to follow-up or whose samples did not pass quality control, they identified seven patients who had microbiological cures, and seven whose disease remained refractory to treatment.

They defined culture conversion at three or more consecutive negative sputum cultures after treatment, collected at least 4 weeks apart, and microbiological cures at maintenance of multiple consecutive negative cultures without any positive cultures of the causative species from respiratory samples.

Infections were deemed to be refractory if there were sustained positive cultures from respiratory samples of causative NTM species after at least 1 year of antibiotic therapy.
 

Diversity analysis

Samples from 8 of the 14 participants had M. abscessus-PD, with the proportion higher among those who had a sustained microbiological cure (71.4% vs. 42.9%).

At baseline, patients with refractory disease were found to have significantly lower alpha diversity, a measure of microbial diversity within a single sample, compared with those whose infections were cured (P = .025).

In addition, samples at 6-month follow-up from those with baseline ­refractory infections ­had differences in the species level of beta-diversity (that is, differences among samples), compared with both baseline and follow-up samples from the cured group (P = .022 and .024, respectively).

The investigators also used linear discriminant analysis to look at taxonomic biomarkers, and observed that several species were more abundant in samples from the microbiological cure group than from the refractory disease group (P < .05) These species included organisms in the Streptococcus pneumoniae group, Prevotella melaninogenica, and Haemophilus parahaemolyticus group.
 

Promising start

A pulmonologist who was not involved in the study commented in an interview that, although the findings need further study, the microbiome of sputum samples has the potential for predictive value.

“I think this will be clinically useful, actually, if we’re able to identify and diagnose patients with MAC disease and then we identify their sputum microbiome, it might give us an idea whether these patients are more sensitive or refractory to treatment,” said Muhammad U. Khawar, MD, from the University of Cincinnati.

Dr. Khawar moderated the session where Dr. Kang reported her data.

The investigators did not report a funding source. Dr. Kang and Dr. Khawar reported that they had no relevant disclosures.
