MONTREAL – Systemic treatment of atopic dermatitis (AD) boosts mood in addition to relieving skin symptoms, according to a prospective, real-world, clinical cohort study presented at the annual meeting of the International Society of Atopic Dermatitis.

“Randomized, controlled, phase 3 studies have shown that systemic treatment of AD reduces depressive symptoms, but whether this holds true in real-world cohorts remains to be shown,” said study investigator Lina Ivert, MD, PhD, of the dermatology and venereology unit in the department of medicine at the Karolinska Institutet, Stockholm.

The study used data from SwedAD, a newly launched web-based Swedish national registry of patients with AD on systemic treatment between June 2017 and August 2021. Participants were followed at 6 and 12 months for the primary outcome of depressive symptoms using the Montgomery–Åsberg Depression Rating Scale–self-report (MADRS-S). Secondary outcomes included the Eczema Area and Severity Index (EASI) score, Patient-Oriented Eczema Measure (POEM), the Dermatology Life Quality Index (DLQI), and pruritus visual analog scale/numeric rating scale (VAS/NRS).

At baseline, 120 patients (median age, 39 years; 57.5% men) were started on dupilumab (n = 91), methotrexate (26), or cyclosporin (3). Although almost half had no depression at baseline, mild depression was present in 29.2%, with moderate and severe depression in 20% and 4.2%, respectively.

Among 59 patients with 6-month follow-up data (48 on dupilumab, 10 on methotrexate, 1 on cyclosporin), all nine depressive symptoms in MADRS-S improved significantly, with reduced sleep improving the most (from a median of 3 points to a median of 1 point). Similarly, overall MADRS-S scores improved (from a median of 14 points to a median of 5; P < .001), as did EASI scores (from a median of 20.5 to 2), POEM scores (from a median of 22 to 6), DLQI (from a median of 15 to 3), and pruritus scores (from a median of 7.1 to 1.8; all P < .001).

The analysis also found a strong correlation between the MADRS-S score and all of the secondary outcomes (P < .001 for all). All these improvements remained significant among the 36 patients with 12-month follow-up data.

“The median MADRS-S reduction also remained when we excluded eight patients who were on antidepressants during the study period, so these results cannot be explained by psychiatric medication,” noted Dr. Ivert, adding that three patients with severe suicide ideation at baseline improved their MADRS-S suicide item to less than 2 points. “So, this study taught us to look at the suicide item score and not only the total MADRS-S score,” she commented.

Comparing patients treated with dupilumab with those treated with methotrexate, the analysis showed that though baseline median MADRS-S scores did not differ significantly between them, there was a significant 6-month reduction in the dupilumab group but not in the methotrexate group.

Asked to comment on the findings, moderator Marissa Joseph, MD, a pediatric dermatologist at the University of Toronto, said that “the mental health effects of inflammatory skin conditions like atopic dermatitis are well known, but whether or not they are well explored in the patient-physician interaction is a whole other scenario.” There are time constraints, she said, adding, “it sometimes takes some deep-diving ... but exploring those types of symptoms is something we need to do more of, and the severity of the disease and reasons for treatment are not just what you can see.”

WASHINGTON – Ridinilazole, a novel, highly specific antibiotic, was safe and showed a sustained clinical response in patients with Clostridioides difficile infection (CDI), according to phase 3 trial results presented at an annual scientific meeting on infectious diseases.

According to the Centers for Disease Control and Prevention, CDI is the top cause of antibiotic-associated diarrhea and one of the most common health care–associated infections in the United States. About 200,000 people in the United States are infected with C. difficile every year in the hospital or clinical care setting.

Most infections are currently treated with vancomycin. Although vancomycin has been shown to be more than 80% effective, it has been linked with recurrence rates ranging from 20% to 30% and interferes with the protective role of the gut microbiome against infection. The current study compared ridinilazole with vancomycin.

Results of the global, double-blinded, randomized trial were presented by Pablo C. Okhuysen, MD, professor of infectious disease at the University of Texas MD Anderson Cancer Center, Houston.

Participants with CDI received a 10-day course of ridinilazole 200 mg twice a day plus placebo or vancomycin 125 mg four times a day. The primary endpoint was sustained clinical response, defined as a clinical response with no recurrent CDI through 30 days after the end of treatment. Recurrent CDI was defined as a new episode of diarrhea with confirmed positive free toxin test requiring additional therapy.

Of the 759 patients enrolled, 745 were included in the modified intention-to-treat  population (ridinilazole, n = 370; vancomycin, n = 375). Ridinilazole achieved a numerically higher rate of sustained clinical response than vancomycin (73.0% vs. 70.7%; P = .467), although the difference was not significant. Ridinilazole also resulted in a significant reduction in recurrence rate (8.1% vs. 17.3%; P < .001).

Ridinilazole’s effect was most notable in a subgroup of patients who were not receiving other antibiotics at time of enrollment – about 70% of participants. In that subgroup, the recurrence rate was 6.7% with ridinilazole versus 16.5% with vancomycin (P < .001), Dr. Okhuysen reported.

“That resulted in a relative risk reduction of 60%,” Dr. Okhuysen told this news organization.

Dr. Okhuysen pointed out that there are currently very few treatment options for CDI other than vancomycin.

“We need new agents to treat C. difficile,” he said, “particularly for those at risk of recurrence. In our study, we found that those exposed to vancomycin had very dramatic shifts in their microbiome.”

Vancomycin depletes the gut microbiome, which decreases the conversion of primary acids to secondary bile acids, the researchers noted.

“A dysbiotic microbiome is fertile ground for C. difficile to grow,” Dr. Okhuysen said. Ridinilazole does not disrupt the microbiome, he added.

Ridinilazole was well-tolerated in the study. The proportion of patients with at least one treatment-emergent adverse effect was 36.4% versus 35.5%, respectively, in the ridinilazole and vancomycin groups. And the proportion who stopped treatment because of treatment-related side effects was 0.8% versus 2.9%.

Mary Hayden, MD, pathology director in the division of infectious diseases at Rush University Medical Center, Chicago, who was not involved with the study, said the results are encouraging as “alternative agents or strategies to prevent recurrence are important to reduce CDI morbidity.”

Its double-blind, randomized, multicenter design strengthens the findings, she explained, adding that “the secondary outcomes of higher concentrations of secondary bile acids and microbiota diversity and composition lend biological plausibility.”

Ridinilazole’s narrow spectrum of activity “should result in less disruption of the colonic microbiota, which has theoretical benefit for both reducing CDI recurrence and for reducing risk of acquisition of multidrug-resistant organisms,” Dr. Hayden said.

Dr. Okhuysen shared that the team is in talks with the Food and Drug Administration and is preparing a manuscript for publication.

The study was supported by Summit Pharmaceuticals and funded by the Biomedical and Advanced Research and Development Authority. Dr. Okhuysen has reported receiving research support from and/or consulting for Summit, Merck, Deinove, Melinta, and Ferring Pharmaceuticals. Some of the coauthors have financial relationships with or received research support from Summit. Dr. Hayden has reported no relevant financial relationships.

VIENNA – The investigational agent xanomeline-trospium (KarXT, Karuna Therapeutics) achieves significant and clinically meaningful improvements in schizophrenia symptom scores without causing problematic adverse effects, new research suggests.

Results from the phase 3 EMERGENT-2 trial, which included more than 250 patients with schizophrenia, showed that those who received xanomeline-trospium for 5 weeks achieved a significant reduction in Positive and Negative Syndrome Scale (PANSS) total scores of more than nine points compared with their peers who received placebo. In addition, the improvements started at week 2.

Alongside significant reductions in both positive and negative symptoms, the results suggest the agent was well tolerated, with treatment-emergent adverse events (TEAEs) largely mild to moderate and transient in nature.

Lead investigator Christoph U. Correll, MD, professor of psychiatry at the Zucker School of Medicine at Hofstra/Northwell, Uniondale, New York, told this news organization that the upcoming EMERGENT-3 study will have a “European component” and that the “readout is expected most likely in the first quarter of next year.”

Dr. Correll suggested that if leads to “two positive studies and reasonable safety,” the novel agent may become part of the “next generation of antipsychotics that are not related to postsynaptic dopamine blockade.”

The findings for EMERGENT-2, presented at the 35th European College of Neuropsychopharmacology (ECNP) Congress as a poster and as an oral presentation, were an update of topline results released earlier this year.
 

Novel compound

Xanomeline-trospium is a novel compound that combines the dual M1/M4-preferring muscarinic receptor agonist effect of xanomeline with the peripherally restricted muscarinic receptor antagonist effect of trospium.

A previous phase 2 trial that compared the drug with placebo in almost 200 patients suggested it significantly reduced psychosis symptoms, leading to the current phase 3 trial.

Dr. Correll noted that xanomeline-trospium reduces psychosis via a “bottom up and top down approach.”

He said that on one hand, M4 agonism decreases acetylcholine in the ventral tegmental area and the associated stratum, “which then decreases dopamine levels from the bottom up,” while the M1 agonism stimulates GABA and decreases dopamine from the “top down.”

M1 agonism, however, also stimulates the cholinergic system peripherally, “which can give you nausea, vomiting, and also some blood pressure and pulse” problems, Dr. Correll said.

That was the limitation when this approach was studied by Lilly as a treatment for patients with Alzheimer’s disease, but the addition of trospium means “you’re buffering somewhat the cholinergic peripheral effects,” he said.

While that can conversely lead to dyspepsia, dry mouth, and constipation, Dr. Correll noted that the adverse effects of the novel agent are “mitigated by titration,” with patients taking up to 8 days to reach the full dose.

The result is that the drug was “overall tolerated, and the effect sizes were quite astounding,” he reported.
 

Intermittent, time limited TEAEs

The current trial included 252 patients aged 18-65 years (mean age, 45 years) who were confirmed to have schizophrenia and who had recently experienced a worsening of psychotic symptoms that warranted hospitalization. Three-quarters of the participants were men, and a similar proportion were Black. Approximately one quarter were White.

All were randomly assigned in a 1:1 ratio to receive either xanomeline-trospium or placebo following a 2-week screening period.

Xanomeline and trospium were titrated from 50 mg/20 mg twice daily to 125 mg/30 mg twice daily, and patients were treated for a total of 5 weeks. Efficacy and safety analyses were conducted in those who had received at least one dose of the study drug.

At the end of the treatment period, xanomeline-trospium was associated with a significant 9.6-point reduction in PANSS total scores relative to placebo; scores fell by 21.2 points with the active treatment, vs. 11.6 points with placebo (P < .0001).

The significant improvement in PANSS total score began at week 2 (P < .05) and continued to accrue over the course of the study.

Xanomeline-trospium was also associated with significant reductions in PANSS positive subscale scores in comparison with placebo (P < .0001), as well as with reductions in PANSS negative subscale scores (P < .01) and PANSS Marder negative subscale scores (P < .01).

Although 75.4% of patients who received xanomeline-trospium experienced a TEAE, in comparison with 58.4% of the placebo group, very few experienced a serious TEAE (just 1.6% in both groups).

TEAEs leading to discontinuation occurred in 7.1% of the active-treatment group, vs. 5.6% of the placebo group. The overall discontinuation rates from the trial were 25% and 21%, respectively.

The most common TEAEs with xanomeline-trospium were constipation (21.4%), dyspepsia (19.0%), nausea (19.0%), vomiting (14.3%), and headache (13.5%).

The results showed that cholinergic TEAEs typically began within the first 2 weeks of treatment and were “intermittent and time limited in nature,” the investigators noted. Moreover, average blood pressure levels were “similar” between the xanomeline-trospium and placebo groups “at each time point throughout the trial,” they added.

Dr. Correll reported that whereas the EMERGENT studies are testing xanomeline-trospium as a monotherapy, the ARISE program will be examining it as an “augmentation” treatment. “And that’s relevant because, let’s face it, patients do not switch” treatments, he said.

He suggested that if xanomeline-trospium is able to have a synergistic effect with other drugs, “we might be able to treat people who are currently not benefiting enough from postsynaptic dopamine blockade to maybe get a little bit closer” to the benefits seen with clozapine, which “also has problematic side effects.”
 

‘Really revolutionary’

Following the oral presentation of the study by coauthor Stephen K. Brannan, MD, chief medical officer, Karuna Therapeutics, Boston, the results were warmly received.

Session cochair Mark Weiser, MD, chairman at the department of psychiatry, Sackler School of Medicine, Tel Aviv University, Israel, said the agent is “really revolutionary in the field.

“It’s a non-dopamine compound which helps for schizophrenia, so we’re all very optimistic about it,” Dr. Weiser added.

Nevertheless, he asked Dr. Brannan whether the occurrence of gastrointestinal adverse effects with xanomeline-trospium led to “functional unblinding of the study.”

Dr. Brannan answered that the investigators were “really worried about this prior to EMERGENT-1” but that formal testing suggested it was not a problem.

Dr. Brannan said that although this has not yet been formally tested for the current trial, he believes that it is “highly unlikely” that functional unblinding occurred, inasmuch as the “percentages are about in the same range as we saw in EMERGENT-1.”

Speaking to ECNP Congress Daily in a conference roundup video, session cochair Andreas Reif, MD, PhD, professor of psychiatry, psychosomatic medicine, and psychotherapy at the University Hospital of Frankfurt (Germany), also highlighted the study.

He said that along with a study of dexmedetomidine sublingual film for agitation associated with schizophrenia or bipolar disorder that was also presented in the session, the current trial is “pivotal.”

Dr. Reif noted that the effect size shown with xanomeline-trospium was “really amazing.”

“We are in a really exciting time in treating mental disorders,” he said. “Industry is finally investing again, and really has new compounds that will make it to the market.”

Karuna plans to submit a new drug application with the Food and Drug Administration for KarXT in mid-2023. The drug is also in development for the treatment of psychiatric and neurologic conditions other than schizophrenia, including Alzheimer’s disease.

The study was funded by Karuna Therapeutics. Dr. Correll has reported relationships with Karuna, as well as AbbVie, Acadia, Alkermes, Allergan, Angelini, Aristo, Axsome, Boehringer-Ingelheim, Cardio Diagnostics, Cerevel, CNX Therapeutics, Compass Pathways, Damitsa, Gedeon Richter, Hikma, Holmusk, IntraCellular Therapies, Janssen/J&J, LB Pharma, Lundbeck, MedAvante-ProPhase, MedInCell, Medscape, Merck, Mindpax, Mitsubishi Tanabe Pharma, Mylan, Neurocrine, Newron, Noven, Otsuka, Pfizer, Pharmabrain, PPD Biotech, Recordati, Relmada, Reviva, Rovi, Seqirus, Servier, SK Life Science, Sumitomo Dainippon, Sunovion, Sun Pharma, Supernus, Takeda, Teva, Viatris, Otsuka, and UpToDate.

Results from the phase 3 EMERGENT-2 trial, which included more than 250 patients with schizophrenia, showed that those who received xanomeline-trospium for 5 weeks achieved a significant reduction in Positive and Negative Syndrome Scale (PANSS) total scores of more than nine points compared with their peers who received placebo. In addition, the improvements started at week 2.

Alongside significant reductions in both positive and negative symptoms, the results suggest the agent was well tolerated, with treatment-emergent adverse events (TEAEs) largely mild to moderate and transient in nature.

Lead investigator Christoph U. Correll, MD, professor of psychiatry at the Zucker School of Medicine at Hofstra/Northwell, Uniondale, New York, told this news organization that the upcoming EMERGENT-3 study will have a “European component” and that the “readout is expected most likely in the first quarter of next year.”

Dr. Correll suggested that if leads to “two positive studies and reasonable safety,” the novel agent may become part of the “next generation of antipsychotics that are not related to postsynaptic dopamine blockade.”

The findings for EMERGENT-2, presented at the 35th European College of Neuropsychopharmacology (ECNP) Congress as a poster and as an oral presentation, were an update of topline results released earlier this year.
 

Novel compound

Xanomeline-trospium is a novel compound that combines the dual M1/M4-preferring muscarinic receptor agonist effect of xanomeline with the peripherally restricted muscarinic receptor antagonist effect of trospium.

A previous phase 2 trial that compared the drug with placebo in almost 200 patients suggested it significantly reduced psychosis symptoms, leading to the current phase 3 trial.

Dr. Correll noted that xanomeline-trospium reduces psychosis via a “bottom up and top down approach.”

He said that on one hand, M4 agonism decreases acetylcholine in the ventral tegmental area and the associated stratum, “which then decreases dopamine levels from the bottom up,” while the M1 agonism stimulates GABA and decreases dopamine from the “top down.”

M1 agonism, however, also stimulates the cholinergic system peripherally, “which can give you nausea, vomiting, and also some blood pressure and pulse” problems, Dr. Correll said.

That was the limitation when this approach was studied by Lilly as a treatment for patients with Alzheimer’s disease, but the addition of trospium means “you’re buffering somewhat the cholinergic peripheral effects,” he said.

While that can conversely lead to dyspepsia, dry mouth, and constipation, Dr. Correll noted that the adverse effects of the novel agent are “mitigated by titration,” with patients taking up to 8 days to reach the full dose.

The result is that the drug was “overall tolerated, and the effect sizes were quite astounding,” he reported.
 

Intermittent, time limited TEAEs

The current trial included 252 patients aged 18-65 years (mean age, 45 years) who were confirmed to have schizophrenia and who had recently experienced a worsening of psychotic symptoms that warranted hospitalization. Three-quarters of the participants were men, and a similar proportion were Black. Approximately one quarter were White.

All were randomly assigned in a 1:1 ratio to receive either xanomeline-trospium or placebo following a 2-week screening period.

Xanomeline and trospium were titrated from 50 mg/20 mg twice daily to 125 mg/30 mg twice daily, and patients were treated for a total of 5 weeks. Efficacy and safety analyses were conducted in those who had received at least one dose of the study drug.

At the end of the treatment period, xanomeline-trospium was associated with a significant 9.6-point reduction in PANSS total scores relative to placebo; scores fell by 21.2 points with the active treatment, vs. 11.6 points with placebo (P < .0001).

The significant improvement in PANSS total score began at week 2 (P < .05) and continued to accrue over the course of the study.

Xanomeline-trospium was also associated with significant reductions in PANSS positive subscale scores in comparison with placebo (P < .0001), as well as with reductions in PANSS negative subscale scores (P < .01) and PANSS Marder negative subscale scores (P < .01).

Although 75.4% of patients who received xanomeline-trospium experienced a TEAE, in comparison with 58.4% of the placebo group, very few experienced a serious TEAE (just 1.6% in both groups).

TEAEs leading to discontinuation occurred in 7.1% of the active-treatment group, vs. 5.6% of the placebo group. The overall discontinuation rates from the trial were 25% and 21%, respectively.

The most common TEAEs with xanomeline-trospium were constipation (21.4%), dyspepsia (19.0%), nausea (19.0%), vomiting (14.3%), and headache (13.5%).

The results showed that cholinergic TEAEs typically began within the first 2 weeks of treatment and were “intermittent and time limited in nature,” the investigators noted. Moreover, average blood pressure levels were “similar” between the xanomeline-trospium and placebo groups “at each time point throughout the trial,” they added.

Dr. Correll reported that whereas the EMERGENT studies are testing xanomeline-trospium as a monotherapy, the ARISE program will be examining it as an “augmentation” treatment. “And that’s relevant because, let’s face it, patients do not switch” treatments, he said.

He suggested that if xanomeline-trospium is able to have a synergistic effect with other drugs, “we might be able to treat people who are currently not benefiting enough from postsynaptic dopamine blockade to maybe get a little bit closer” to the benefits seen with clozapine, which “also has problematic side effects.”
 

‘Really revolutionary’

Following the oral presentation of the study by coauthor Stephen K. Brannan, MD, chief medical officer, Karuna Therapeutics, Boston, the results were warmly received.

Session cochair Mark Weiser, MD, chairman at the department of psychiatry, Sackler School of Medicine, Tel Aviv University, Israel, said the agent is “really revolutionary in the field.

“It’s a non-dopamine compound which helps for schizophrenia, so we’re all very optimistic about it,” Dr. Weiser added.

Nevertheless, he asked Dr. Brannan whether the occurrence of gastrointestinal adverse effects with xanomeline-trospium led to “functional unblinding of the study.”

Dr. Brannan answered that the investigators were “really worried about this prior to EMERGENT-1” but that formal testing suggested it was not a problem.

Dr. Brannan said that although this has not yet been formally tested for the current trial, he believes that it is “highly unlikely” that functional unblinding occurred, inasmuch as the “percentages are about in the same range as we saw in EMERGENT-1.”

Speaking to ECNP Congress Daily in a conference roundup video, session cochair Andreas Reif, MD, PhD, professor of psychiatry, psychosomatic medicine, and psychotherapy at the University Hospital of Frankfurt (Germany), also highlighted the study.

He said that along with a study of dexmedetomidine sublingual film for agitation associated with schizophrenia or bipolar disorder that was also presented in the session, the current trial is “pivotal.”

Dr. Reif noted that the effect size shown with xanomeline-trospium was “really amazing.”

“We are in a really exciting time in treating mental disorders,” he said. “Industry is finally investing again, and really has new compounds that will make it to the market.”

Karuna plans to submit a new drug application with the Food and Drug Administration for KarXT in mid-2023. The drug is also in development for the treatment of psychiatric and neurologic conditions other than schizophrenia, including Alzheimer’s disease.

The study was funded by Karuna Therapeutics. Dr. Correll has reported relationships with Karuna, as well as AbbVie, Acadia, Alkermes, Allergan, Angelini, Aristo, Axsome, Boehringer-Ingelheim, Cardio Diagnostics, Cerevel, CNX Therapeutics, Compass Pathways, Damitsa, Gedeon Richter, Hikma, Holmusk, IntraCellular Therapies, Janssen/J&J, LB Pharma, Lundbeck, MedAvante-ProPhase, MedInCell, Medscape, Merck, Mindpax, Mitsubishi Tanabe Pharma, Mylan, Neurocrine, Newron, Noven, Otsuka, Pfizer, Pharmabrain, PPD Biotech, Recordati, Relmada, Reviva, Rovi, Seqirus, Servier, SK Life Science, Sumitomo Dainippon, Sunovion, Sun Pharma, Supernus, Takeda, Teva, Viatris, Otsuka, and UpToDate.

Pediatric patients with epilepsy have an increased risk of cardiovascular complications later in life, but little is known about how they progress. A new study finds that abnormalities in electrocardiograms are linked to an earlier age of diagnosis and longer epilepsy duration.

The findings could help researchers in the search for biomarkers that could predict later problems in children with epilepsy. “In pediatric neurology I think we’re a little bit removed from some of the cardiovascular complications that can happen within epilepsy, but cardiovascular complications are well established, especially in adults that have epilepsy. Adults with epilepsy are more likely to have coronary artery disease, atherosclerosis, arrhythmias, heart attacks, and sudden cardiac death. It’s a pretty substantial difference compared with their nonepileptic peers. So knowing that, the big question is, how do these changes develop, and how do we really counsel our patients in regards to these complications?” said Brittnie Bartlett, MD, during her presentation of the research at the 2022 annual meeting of the Child Neurology Society.

Identifying factors that increase cardiac complications

Previous studies suggested that epilepsy duration might be linked to cardiovascular complications. In children with Dravet syndrome, epilepsy duration has been shown to be associated with cardiac complications. Pathological T wave alternans, which indicates ventricular instability, has been observed in adults with longstanding epilepsy but not adults with newly diagnosed epilepsy.

“So our question in this preliminary report of our data is: What factors in our general pediatric epilepsy cohort can we identify that put them at a greater risk for having EKG changes, and specifically, we wanted to verify these findings from the other studies that epilepsy duration is, in fact, a risk factor for these EKG changes in general [among children] with epilepsy aside from channelopathies,” said Dr. Bartlett, who is an assistant professor at Baylor College of Medicine and a child neurologist at Texas Children’s Hospital, both in Houston.

She presented a striking finding that cardiovascular changes appear early. “The most important thing I want you all to make note of is the fact that, in this baseline study that we got on these kids, 47% already had changes that we were seeing on their EKGs,” said Dr. Bartlett.

The researchers also looked for factors associated with EKG changes, and found that duration of epilepsy and age at diagnosis were the two salient factors. “Our kids that did have EKG changes present had an average epilepsy duration of 73 months, as opposed to [the children] that did not have EKG changes and had an average epilepsy duration of 46 months,” said Dr. Bartlett.

Other factors, such epilepsy type, etiology, refractory epilepsy, and seizure frequency had no statistically significant association with EKG changes. They also saw no associations with high-risk seizure medications, even though some antiseizure drugs have been shown to be linked to EKG changes.

“We were able to confirm our hypothesis that EKG changes were more prevalent with longer duration of epilepsy. Unfortunately, we weren’t able to find any other clues that would help us counsel our patients, but this is part of a longitudinal prospective study that we’ll be following these kids over a couple of years’ time, so maybe we’ll be able to tease out some of these differences. Ideally, we’d be able to find some kind of a biomarker for future cardiovascular complications, and right now we’re working with some multivariable models to verify some of these findings,” said Dr. Bartlett.

Implications for clinical practice

During the Q&A, Dr. Bartlett was asked if all kids with epilepsy should undergo an EKG. She recommended against it for now. “At this point, I don’t think we have enough clear data to support getting an EKG on every kid with epilepsy. I do think it’s good practice to do them on all kids with channelopathies. As a general practice, I tend to have a low threshold towards many kids with epilepsy, but a lot of these cardiovascular risk factors tend to pop up more in adulthood, so it’s more preventative,” she said.

Grace Gombolay, MD, who moderated the session where the poster was presented, was asked for comment on the study. “What’s surprising about it is that up to half of patients actually had EKG changes, different what from what we see in normal population, and it’s interesting to think about the implications. One of the things that our epilepsy patients are at risk for is SUDEP – sudden, unexplained death in epilepsy. It’s interesting to think about what these EKG changes mean for clinical care. I think it’s too early to say at this time, but this might be one of those markers for SUDEP,” said Dr. Gombolay, who is an assistant professor at Emory University, Atlanta, and director of the Pediatric Neuroimmunology and Multiple Sclerosis Clinic at Children’s Healthcare of Atlanta.

The researchers prospectively studied 213 patients who were recruited. 46% were female, 42% were white, 41% were Hispanic, and 13% were African American. The mean age at enrollment was 116 months, and mean age of seizure onset was 45 months.

The researchers found that 47% had abnormal EKG readings. None of the changes were pathologic, but they may reflect changes to cardiac electrophysiology, according to Dr. Bartlett. Those with abnormal readings were older on average (11.6 vs. 8.3 years; P < .005) and had a longer epilepsy duration (73 vs. 46 months; P = .004).

Dr. Gombolay has no relevant financial disclosures.

CINCINNATI – Cerebral palsy affects about 3 in every 1,000 children, but there is usually little sign of the condition at birth. Instead, it usually shows clinical manifestation between ages 2 and 5, and a diagnosis can trigger early interventions that can improve long-term outcomes.

Physicians and patients would benefit from a screening method for cerebral palsy at birth, but that has so far eluded researchers.

At the 2022 annual meeting of the Child Neurology Society, researchers presented evidence that respiratory rate measured in the last 24 hours of residence in the neonate intensive care unit (NICU) predicts later onset of cerebral palsy, with higher variability associated with increased cerebral palsy risk.

The study results were promising, according to Marc Patterson, MD, who comoderated the session. “It gives us more confidence in predicting the children at risk and making sure that they’re going to be followed closely to get the interventions they need to help them,” said Dr. Patterson, who is a professor of neurology, pediatrics, and medical genetics at Mayo Medical School in Rochester, Minn.

“By the time a child is 5 or 6, the symptoms are usually very obvious, but you really want to intervene as soon as possible before their brain’s plasticity decreases over time, so the earlier you can intervene in general, the better your results are going to be,” said Dr. Patterson.

There are tools available to diagnose cerebral palsy at an earlier age, including the Prechtl General Movements Assessment (GMA), which can be done up to 5 months of corrected age. It has 97% sensitivity and 89% specificity for cerebral palsy. The Hammersmith Infant Neurological Examination (HINE), which can be used in the same age range, and has 72-91% sensitivity and 100% specificity.

Both of the available tools are resource intensive and require trained clinicians, and may be unavailable in many areas. Despite these tools, early diagnosis of cerebral palsy is still underemployed, according to Arohi Saxena, a third-year medical student at Washington University in St. Louis, who presented the study results.
 

Respiratory rate variability may indicate increased risk

The researchers set out to identify objective metrics that correlated with HINE and GMA scores. They looked at kinematic data from practical assessments carried out by their physical therapists, as well as vital sign instability obtained at NICU discharge, which was based on suggestions that hemodynamic instability may be linked to later risk of cerebral palsy, according to Ms. Saxena.

They analyzed data from 31 infants with a corrected age of 8-25 weeks at a tertiary NICU follow-up clinic. Of these, 18 displayed fidgety movements on their Prechtl assessment, and 13 did not.

They used DeepLabCut software to analyze data from videos of the Prechtl assessment, with a focus on range and variance of hand and foot movements normalized to nose-to-umbilicus distance. They also analyzed pulse and respiratory data from the final 24 hours before NICU discharge.

They found that infants without fidgety movements had decreased hand and foot movement ranges (P = .04). There was no significant difference between the two groups with respect to pulse measurements. However, the respiratory rate range and variance was significantly higher in infants without fidgety movements. “Infants who are at higher risk for developing cerebral palsy had more respiratory instability early on in life,” said Ms. Saxena during her talk.

When they compared values to HINE scores, they found a correlation with less foot movement and a predisposition to develop cerebral palsy, but no correlation with hand movement. A lower HINE sore also correlated to larger respiratory rate range and variance (P < .01 for both).

“Our hypothesis to explain this link is that respiratory rate variability is likely driven by neonatal injury in the brainstem, where the respiratory centers are located. In some infants, this may correlate with more extensive cerebral injury that could predict the development of cerebral palsy,” said Ms. Saxena.

The group plans to increase its sample size as well as to conduct long-term follow-up on the infants to see how many receive formal diagnoses of cerebral palsy.

After her talk, asked by a moderator why motor assessments were not a reliable predictor in their study, Ms. Saxena pointed to the inexperience of assessors at the institution, where Prechtl testing had only recently begun.

“I think a lot of it is to do with the more subjective nature of the motor assessment. We definitely saw kind of a trend where in the earlier data that was collected, right when our institutions started doing these Prechtls, it was even less of a reliable effect. So I think possibly as clinicians continue to get more familiar with this assessment and there’s more like a validated and robust scoring system, maybe we’ll see a stronger correlation,” she said.

CINCINNATI – Cerebral palsy affects about 3 in every 1,000 children, but there is usually little sign of the condition at birth. Instead, it usually shows clinical manifestation between ages 2 and 5, and a diagnosis can trigger early interventions that can improve long-term outcomes.

Physicians and patients would benefit from a screening method for cerebral palsy at birth, but that has so far eluded researchers.

At the 2022 annual meeting of the Child Neurology Society, researchers presented evidence that respiratory rate measured in the last 24 hours of residence in the neonate intensive care unit (NICU) predicts later onset of cerebral palsy, with higher variability associated with increased cerebral palsy risk.

The study results were promising, according to Marc Patterson, MD, who comoderated the session. “It gives us more confidence in predicting the children at risk and making sure that they’re going to be followed closely to get the interventions they need to help them,” said Dr. Patterson, who is a professor of neurology, pediatrics, and medical genetics at Mayo Medical School in Rochester, Minn.

Visits to the emergency department for asthma increase more than a year before a failed inspection by the U.S. Department of Housing and Urban Development (HUD), according to a new study presented at the annual meeting of the American College of Emergency Physicians.

While links between asthma and low-quality housing prone to harboring allergens have been well-documented, the current study takes the extra step of looking at housing down to the level of individual land parcels and suggests that asthma hospital visits can be used to identify hazardous housing earlier.

“Emergency department visits for asthma provide a leading indicator that can be used by health departments or housing authorities to direct housing inspections and remediation of poor housing conditions, track improvements in housing quality, measure housing department performance, support resident grievances, and inform funding allocation decisions,” said the study’s lead researcher, Elizabeth Samuels, MD, who is assistant professor of epidemiology and emergency medicine at Brown University, Providence, R.I.

Researchers retrospectively looked at cases of children and adults in the Greater New Haven area of Connecticut seen at the Yale New Haven Hospital ED for asthma-related problems between March 2013 and August 2017. The region has the fifth-highest prevalence of asthma in the United States, the researchers point out, due to its air quality, pollens, and quality of its housing. More than half of residences were built before 1,940, compared with about 13% nationally. Patient addresses were matched with HUD inspection records.

The review encompassed 11,429 ED visits by 6,366 individuals; 54% were insured by Medicaid, and 42% were Black. Controlling for patient and neighborhood data, researchers found that increased asthma ED visits at the parcel level were associated with decreased HUD inspection scores to a highly significant degree (P < .001).

They also found that there was a relationship in terms of timing between asthma ED visits and inspection scores: asthma ED visits increased more than 1 year before a failed HUD inspection. They also found that asthma ED visits were not elevated at housing units that passed inspection. Using asthma ED visits to predict failed housing inspections produced a specificity rate of 92.3% in an adjusted model, Dr. Samuels noted.

“This approach represents a novel method of early identification of dangerous housing conditions, which could aid in the prevention of asthma-related morbidity and mortality,” Dr. Samuels said.

The investigators noted that, of the parcels with the top three incidence rates of asthma ED visits, “all of them have been closed or demolished.”

In addition to limiting exposure of patients with asthma to the allergens of mold, mice and rats, and cockroaches, improving poor-quality housing earlier could help asthma by reducing stress, she said.

“There is also an increasing evidence base that psychosocial stress increases the risk of asthma attacks, and it’s therefore possible that living in poor housing conditions – often highly stressful situations – drives exacerbation risk via this pathway,” she said. “Synergistic effects between these pathways are also possible or even likely.”

Neeta Thakur, MD, associate professor of medicine at the University of California, San Francisco, who researches asthma, said the findings could lead to a strategy for improving poor-quality housing more quickly. As it is, inspections are too infrequent, often prompted by resident complaints.

“Once the complaints get to a certain threshold, then there might be an inspection that happens, and if there is a periodic review of the buildings, they often happen few and far between,” she said. “We could actually use some of the information that we’re already getting from something like ED visits and see if there is a pattern.”

An important follow-up would be to see whether asthma outcomes improve after housing deficiencies are addressed and whether the predictive capacity of ED visits occurs in other places.

“Would you then see a decline in the ED visit rates from individuals living in those buildings?” Dr. Thakur said. “It’s important to find a leading indicator, but you want to be sure that that leading indicator is useful as something that can be intervened upon.”

Dr. Samuels and Dr. Thakur have reported no relevant financial relationships.

NASHVILLE, TENN. – In a growing number of states, pulmonologists face serious legal consequences for advising women who have an underlying medical condition that places them at risk for life-threatening complications from pregnancy or childbirth, according to a panel of experts assembled for a special session at the annual meeting of the American College of Chest Physicians.

Following the June 24 decision by the U.S. Supreme Court to overturn Roe v. Wade, several states were swift to enact tight restrictions on abortion. These restrictions include bans on elective abortions for almost any reason. Worded in various ways, the new laws typically include exceptions when the health of the mother is threatened, but these exceptions must be navigated carefully.

As a general rule, “there is no clear and specific definition of when the mother’s life is at risk. These laws are vague on purpose,” said Rebecca Cohen, MD, division chief, Complex Family Planning, University of Colorado at Denver, Aurora.

The remarks were relevant to any clinician who advises women regarding pregnancy termination, but Dr. Cohen’s advice was tailored to pulmonologists. Advances have reduced the proportion of women with severe lung diseases, such as pulmonary arterial hypertension or interstitial lung disease, that make pregnancy untenable, but serious risks persist.

Clinicians need to assume a defensive posture, and the first step is to understand the laws, according to Dr. Cohen. For this, she recommended the nongovernmental Guttmacher Institute as a resource. With a focus on sexual and reproductive health, this research institute maintains a state-by-state summary of laws that govern pregnancy termination. The laws are being reconsidered across the country, and Dr. Cohen said the website updates its summaries accordingly.

In states with the most rigorous restrictions, the risks to physicians are substantial. Pulmonologists need to recognize that they might face legal consequences from merely advising a patient to terminate her pregnancy if the medical need is ambiguous or unclear, according to Dr. Cohen.

“If the advice is interpreted as aiding and abetting an elective abortion, it is a felony offense in some states,” Dr. Cohen said.

In states with restrictive laws, pregnancy prevention is the safest approach for women of childbearing age who face life-threatening complications in the event of pregnancy, according to Dr. Cohen. This might reasonably include a step beyond standard contraception. Dr. Cohen mentioned such approaches as period tracking to double down.

In addition, for women of childbearing age with health problems that might result in complications in the event of a pregnancy, it is appropriate to establish this fact in the medical record. This history could prove useful for maximizing options when making decisions in the best interest of the mother’s health in the event of contraception failure.

In addition, pulmonologists who counsel women about the potential for pregnancy termination should consider establishing a relationship with the legal department at the institution where they work, according to Dr. Cohen. In specific cases in which termination is recommended, she further advised building documentation with participation from additional medical specialists, such as an obstetrician who manages high-risk pregnancies.

“There is no guarantee that any given documentation is adequate,” Dr. Cohen warned. She indicated that consensus from multiple clinicians can strengthen the legal defense if one is necessary.

For some serious lung conditions that are incompatible with pregnancy, the threat to the mother’s life can occur early, according to Deborah Jo Levine, MD, a clinical instructor in the division of pulmonary, allergy, and critical care medicine, Stanford (Calif.) University.

As a result, “you need to identify at-risk patients early and develop a plan promptly,” said Dr. Levine, who joined Dr. Cohen on the special panel at the CHEST 2022 meeting. Even when termination is medically appropriate, restrictive laws are making these services harder to find.

In the case of a pregnancy likely to pose a high risk of complications owing to the patient’s having lung disease, “it is important to involve a high-risk ob quickly,” Dr. Levine warned. “In some cases, termination poses less risk if performed early.”

Sunjay R. Devarajan, MD, assistant professor of pulmonary medicine and critical care, Baylor College of Medicine, Houston, has faced this issue in a state that has some of the most restrictive laws. Even when there is no debate about the necessity of a medically indicated abortion, he cautioned that abortion services are becoming harder to find.

“A recent patient who had a complicated unintentional pregnancy on our service had to go out of state for pregnancy termination,” Dr. Devarajan said. He noted that this option is not available to all women, particularly in states such as his own in which most bordering states also now have highly restrictive abortion laws.

On the basis of this experience, he is thinking more defensively. Now that clinicians can be drawn into legal proceedings even when pregnancy termination is indicated, he agreed that clinicians must become familiar with the local laws.

“We are doing better in managing pregnancies in women with serious lung diseases, but termination is still the prudent approach in some cases,” Dr. Devarajan said. He indicated that he considered the advice offered by Dr. Cohen helpful in avoiding complications for the patient and the physician.

Dr. Cohen, Dr. Levine, and Dr. Devarajan have disclosed no relevant financial relationships.

“We are doing better in managing pregnancies in women with serious lung diseases, but termination is still the prudent approach in some cases,” Dr. Devarajan said. He indicated that he considered the advice offered by Dr. Cohen helpful in avoiding complications for the patient and the physician.

NASHVILLE, TENN. – In a growing number of states, pulmonologists face serious legal consequences for advising women who have an underlying medical condition that places them at risk for life-threatening complications from pregnancy or childbirth, according to a panel of experts assembled for a special session at the annual meeting of the American College of Chest Physicians.

Following the June 24 decision by the U.S. Supreme Court to overturn Roe v. Wade, several states were swift to enact tight restrictions on abortion. These restrictions include bans on elective abortions for almost any reason. Worded in various ways, the new laws typically include exceptions when the health of the mother is threatened, but these exceptions must be navigated carefully.

As a general rule, “there is no clear and specific definition of when the mother’s life is at risk. These laws are vague on purpose,” said Rebecca Cohen, MD, division chief, Complex Family Planning, University of Colorado at Denver, Aurora.

The remarks were relevant to any clinician who advises women regarding pregnancy termination, but Dr. Cohen’s advice was tailored to pulmonologists. Advances have reduced the proportion of women with severe lung diseases, such as pulmonary arterial hypertension or interstitial lung disease, that make pregnancy untenable, but serious risks persist.

Clinicians need to assume a defensive posture, and the first step is to understand the laws, according to Dr. Cohen. For this, she recommended the nongovernmental Guttmacher Institute as a resource. With a focus on sexual and reproductive health, this research institute maintains a state-by-state summary of laws that govern pregnancy termination. The laws are being reconsidered across the country, and Dr. Cohen said the website updates its summaries accordingly.

In states with the most rigorous restrictions, the risks to physicians are substantial. Pulmonologists need to recognize that they might face legal consequences from merely advising a patient to terminate her pregnancy if the medical need is ambiguous or unclear, according to Dr. Cohen.

“If the advice is interpreted as aiding and abetting an elective abortion, it is a felony offense in some states,” Dr. Cohen said.

In states with restrictive laws, pregnancy prevention is the safest approach for women of childbearing age who face life-threatening complications in the event of pregnancy, according to Dr. Cohen. This might reasonably include a step beyond standard contraception. Dr. Cohen mentioned such approaches as period tracking to double down.

In addition, for women of childbearing age with health problems that might result in complications in the event of a pregnancy, it is appropriate to establish this fact in the medical record. This history could prove useful for maximizing options when making decisions in the best interest of the mother’s health in the event of contraception failure.

In addition, pulmonologists who counsel women about the potential for pregnancy termination should consider establishing a relationship with the legal department at the institution where they work, according to Dr. Cohen. In specific cases in which termination is recommended, she further advised building documentation with participation from additional medical specialists, such as an obstetrician who manages high-risk pregnancies.

“There is no guarantee that any given documentation is adequate,” Dr. Cohen warned. She indicated that consensus from multiple clinicians can strengthen the legal defense if one is necessary.

For some serious lung conditions that are incompatible with pregnancy, the threat to the mother’s life can occur early, according to Deborah Jo Levine, MD, a clinical instructor in the division of pulmonary, allergy, and critical care medicine, Stanford (Calif.) University.

As a result, “you need to identify at-risk patients early and develop a plan promptly,” said Dr. Levine, who joined Dr. Cohen on the special panel at the CHEST 2022 meeting. Even when termination is medically appropriate, restrictive laws are making these services harder to find.

In the case of a pregnancy likely to pose a high risk of complications owing to the patient’s having lung disease, “it is important to involve a high-risk ob quickly,” Dr. Levine warned. “In some cases, termination poses less risk if performed early.”

Sunjay R. Devarajan, MD, assistant professor of pulmonary medicine and critical care, Baylor College of Medicine, Houston, has faced this issue in a state that has some of the most restrictive laws. Even when there is no debate about the necessity of a medically indicated abortion, he cautioned that abortion services are becoming harder to find.

“A recent patient who had a complicated unintentional pregnancy on our service had to go out of state for pregnancy termination,” Dr. Devarajan said. He noted that this option is not available to all women, particularly in states such as his own in which most bordering states also now have highly restrictive abortion laws.

On the basis of this experience, he is thinking more defensively. Now that clinicians can be drawn into legal proceedings even when pregnancy termination is indicated, he agreed that clinicians must become familiar with the local laws.

“We are doing better in managing pregnancies in women with serious lung diseases, but termination is still the prudent approach in some cases,” Dr. Devarajan said. He indicated that he considered the advice offered by Dr. Cohen helpful in avoiding complications for the patient and the physician.

There does not appear to be a definitive clinical link between new-onset parkinsonism and SARS-CoV-2 (COVID-19) infection, a multinational team of researchers reported at the International Congress of Parkinson’s Disease and Movement Disorders.

SARS-CoV-2 led to numerous discussions about a potential post–COVID-19 emergence of new-onset parkinsonism in susceptible individuals, often referred to in the literature as a “perfect storm” or a “wave” of parkinsonism, according to lead study author Iro Boura, MD.
 

Postviral precedence

“Although pathogens have been associated both with parkinsonism cases and Parkinson’s disease pathogenesis, the main concern of a potential connection between COVID-19 and new-onset parkinsonism arose from the historically documented parkinsonism cases appearing with encephalitis lethargica,” said Dr. Boura, a PhD candidate with the University of Crete in Greece and ex-fellow at King’s College London.

Encephalitis lethargica appeared between 1916 and 1930 and has been epidemiologically related to the Spanish influenza pandemic, “although this link has been strongly debated by other researchers,” she added.

Because the connection of COVID-19 and parkinsonism seemed highly speculative, Dr. Boura and movement disorder specialist Kallol Ray Chaudhuri DSc, FRCP, MD, decided to search for any data supporting this notion. “Such a possibility would have a significant impact on everyday practice, including long follow-up neurological assessments of COVID-19 patients, along with greater vigilance in recognizing potential symptoms,” said Dr. Boura.  

They found no organized research exploring this link, aside from published case reports.
 

Scant evidence of a parkinsonism wave

The investigators conducted a review of the literature up to February 2022 to identify and analyze published cases of new-onset parkinsonism following a confirmed SARS-CoV-2 infection in otherwise healthy individuals. They ended up with 20 such cases.

Although some cases presented during or shortly after a COVID-19 infection, “the numbers are currently quite low to draw safe conclusions and generalize these findings as a risk of parkinsonism for the general population,” said Dr. Boura. Overall, parkinsonism appeared in the context of encephalopathy in 11 patients. Four patients developed postinfectious parkinsonism without encephalopathy. Another four had phenotypic similarities to idiopathic Parkinson’s disease. 

Nine patients were responsive to levodopa, while four required immunomodulatory treatment.

Although cases have already been reported, current data do not yet justify the concept of a post–COVID-19 parkinsonism wave. However, long-term surveillance is crucial to ensure that reports of further cases are carefully documented and analyzed.

Dr. Chaudhuri’s research team recently wrote a book exploring the numerous aspects of COVID-19 and parkinsonism, including Parkinson’s disease, said Dr. Boura.

“Moreover, the COVID-19 Clinical Neuroscience Study (COVID-CNS), with serial follow-up visits for COVID-19 patients, including imaging, is currently running in the United Kingdom with the active participation of Prof Chaudhuri’s team, aiming at revealing any potential parkinsonism cases after a COVID-19 infection,” she said.

Researchers have developed a computer program to identify drugs for other diseases that might be repurposed to treat type 2 diabetes and/or obesity by targeting genetic pathways for these two conditions.

The scientists identified four pathways with known drug targets for type 2 diabetes and five with known drug targets for obesity.

Their findings suggest that:

• Palbociclib (used to treat breast cancer) and cardiac glycosides (used to treat heart failure and heart rhythm disorders) might be repurposed to treat type 2 diabetes.
• Baclofen (a muscle relaxant) and carfilzomib (a chemotherapy) could potentially be used to treat obesity.
• Fostamatinib (used to treat thrombocytopenia), sucralfate (used to treat stomach ulcers), and regorafenib (used to treat cancer) might be used to treat type 2 diabetes and obesity.
• Baclofen and sucralfate would have favorable safety profiles as repurposed treatments.

Sahar El Shair, a PhD student at the Faculty of Health and Medicine, University of Newcastle, New South Wales, Australia, presented the research during an oral session at the International Congress on Obesity, the biennial congress of the World Obesity Federation, in Melbourne.

“New treatments with higher activity and specificity are urgently needed to tackle a pandemic of chronic illness associated with type 2 diabetes and obesity,” senior coauthor Murray Cairns, PhD, said in a press release from the ICO.   

“Our technology harnesses genetically informed precision medicine to identify and target new treatments for these complex disorders,” said Dr. Cairns, from the school of biomedical sciences and pharmacy at the University of Newcastle.

Matchmaking between individual, their genetic traits, and drugs

Dr. Cairns and senior coauthor William Reay, PhD, also from the school of biomedical sciences and pharmacy, have cofounded a company called PolygenRx.

The company website explains that they have developed a propriety platform termed the pharmagenic enrichment score (PES), which is “essentially a matchmaking service between patients and drugs, allowing treatment to be optimized for each individual using their unique combination of genetic risk factors.”

It is important to note the genetic risk from complex traits, such as type 2 diabetes and obesity, “are quite different [from] the rare genetic disorders caused mostly by a devastating mutation in a single gene,” Dr. Cairns explained in an email.

“Complex traits,” he noted, “are associated with thousands of [genetic] variants that are common in people and have a cumulative effect.”

For this specific research, the investigators obtained genetic data from genome-wide association studies of obesity and type 2 diabetes.

“By using very large cohorts (hundreds of thousands of individuals) and comparing the frequency of millions of genetic variants in subjects with these conditions with controls, these studies have revealed regions of the genome and genes associated with the condition,” Dr. Cairns noted.

The pharmagenic enrichment score integrates a person’s genetics with drug pharmacology to determine if a person would respond more readily to a certain drug.

“We are investigating the potential of thousands of drugs across a broad spectrum of complex traits (the list is almost endless),” Dr. Cairns explained.

From the PES score, “we have an estimate of each individual’s likelihood of a positive response to said drug,” he noted. “We all have variants that increase (and decrease) the risk of these conditions to various degrees as they are common (high frequency) genetic variants.”

With this research, “we can implement this precision medicine strategy to match the right [repurposed] drugs for individuals based on their specific burden of genetic risk” for obesity and type 2 diabetes.

“Drug repurposing can be a fast track to new medicines because there is existing knowledge about their safety and activity in humans,” he said.

Next steps: Raising funds for clinical trials

“We would like to progress some of these compounds to preclinical and clinical trials,” Dr. Cairns said, “but need to raise the funds for this expensive research. With limited government research funding opportunities, we have recently spun out a startup company to attract commercial investment in our platform and the development of new drug candidates.”

The authors have reported no relevant financial relationships. Dr. Reay and Dr. Cairns are cofounders of PolygenRx.

Patients with iron deficiency anemia who developed bacterial pneumonia showed improved outcomes compared to those without iron deficiency anemia, based on data from more than 450,000 individuals in the National Inpatient Sample.

Iron deficiency is the most common nutritional deficiency worldwide, and can lead to anemia, but iron also has been identified as essential to the survival and growth of pathogenic organisms, Mubarak Yusuf, MD, said in a presentation at the annual meeting of the American College of Chest Physicians (CHEST).

However, the specific impact of iron deficiency anemia (IDA) on outcomes in patients hospitalized with acute bacterial infections has not been explored, said Dr. Yusuf, a third-year internal medicine resident at Lincoln Medical Center in New York.

In the study, Dr. Yusuf and colleagues reviewed data from the Nationwide Inpatient Sample (NIS) Database for 2016-2019. They identified 452,040 adults aged 18 or older with a primary diagnosis of bacterial pneumonia based on ICD-10 codes. Patients with a principal diagnosis other than bacterial pneumonia were excluded.

Of these, 5.5% had a secondary diagnosis of IDA. The mean age of the study population was similar between the IDA and non-IDA groups (68 years) and racial distribution was similar, with a White majority of approximately 77%. Slightly more patients in the IDA group were women (58.5% vs. 51.6%) and this difference was statistically significant (P < .00001). Most of the patients (94.6%) in the IDA group had at least three comorbidities, as did 78.1% of the non-IDA group.

The primary outcome was mortality, and the overall mortality in the study population was 2.89%. Although the mortality percentage was higher in the IDA group compared to the non-IDA group (3.25% vs. 2.87%), “when we adjusted for confounders, we noticed a decreased odds of mortality in the IDA group” with an adjusted odds ratio of 0.74 (P = .001), Dr. Yusuf said.

In addition, secondary outcomes of septic shock, acute respiratory failure, and cardiac arrest were lower in the IDA group in a regression analysis, with adjusted odds ratios of 0.71, 0.78, and 0.57, respectively.

The mean length of stay was 0.3 days higher in the IDA group, and the researchers found a nonsignificant increase in total hospital costs of $402.5 for IDA patients compared to those without IDA, said Dr. Yusuf.

The take-home message from the study is actually a question to the clinician, Dr. Yusuf said. “Should you consider a delay in treatment [of iron deficiency anemia] if the patient is not symptomatic?” he asked.

More research is needed to investigate the improved outcomes in the iron deficient population, but the large sample size supports an association that is worth exploring, he concluded.

“The findings of this research may suggest a protective effect of iron deficiency in acute bacterial pneumonia,” Dr. Yusuf said in a press release accompanying the meeting presentation. “More research is needed to elucidate the improved outcomes found in this population, but this research may lead clinicians to consider a delay in treatment of nonsymptomatic iron deficiency in acute bacterial infection,” he added.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Most of the patients (94.6%) in the IDA group had at least three comorbidities, as did 78.1% of the non-IDA group.

The primary outcome was mortality, and the overall mortality in the study population was 2.89%. Although the mortality percentage was higher in the IDA group compared to the non-IDA group (3.25% vs. 2.87%), “when we adjusted for confounders, we noticed a decreased odds of mortality in the IDA group” with an adjusted odds ratio of 0.74 (P = .001), Dr. Yusuf said.

In addition, secondary outcomes of septic shock, acute respiratory failure, and cardiac arrest were lower in the IDA group in a regression analysis, with adjusted odds ratios of 0.71, 0.78, and 0.57, respectively.

The mean length of stay was 0.3 days higher in the IDA group, and the researchers found a nonsignificant increase in total hospital costs of $402.5 for IDA patients compared to those without IDA, said Dr. Yusuf.

The take-home message from the study is actually a question to the clinician, Dr. Yusuf said. “Should you consider a delay in treatment [of iron deficiency anemia] if the patient is not symptomatic?” he asked.

More research is needed to investigate the improved outcomes in the iron deficient population, but the large sample size supports an association that is worth exploring, he concluded.

“The findings of this research may suggest a protective effect of iron deficiency in acute bacterial pneumonia,” Dr. Yusuf said in a press release accompanying the meeting presentation. “More research is needed to elucidate the improved outcomes found in this population, but this research may lead clinicians to consider a delay in treatment of nonsymptomatic iron deficiency in acute bacterial infection,” he added.

The study received no outside funding. The researchers had no financial conflicts to disclose.
