Imaging links insula and frontal cortex to anxiety in Parkinson’s disease

Article Type
Changed

The insula and frontal cortex are involved in the development of anxiety in adults with Parkinson’s disease, according to imaging data from 108 individuals.

Anxiety occurs in approximately 31% of Parkinson’s disease patients, but the underlying mechanisms are not well understood, wrote Nacim Betrouni, MD, of the University of Lille, France, and colleagues. Previous research has shown associations between anxiety severity and increased activity in brain areas of emotion processing, based on MRI and positron emission tomography, but electroencephalography (EEG) has not been widely used, they said.

In a study published in Neurophysiologie Clinique , the researchers compared EEG spectral patterns and functional resting-state networks in Parkinson’s disease patients with and without anxiety disorders. They identified data from 33 PD patients who met criteria for anxiety, and 75 without anxiety. The average age of the patients was 65 years, and the average disease duration was 9.76 years in anxiety patients and 7.83 years in patients without anxiety.

Overall, findings on spectral analysis showed an association between anxiety and changes in the alpha activity in the right frontal cortex, the researchers said. They also found the relative power in the alpha1 frequency band in the right prefrontal cortex was lower in patients with anxiety than without; this finding was significantly associated with avoidance behavior on a subscale of the Parkinson’s Anxiety Scale (PAS_C, P = .035). A trend toward a significant association with episodic anxiety was noted (PAS_B, P = .06), but no significant associations were noted for persistent anxiety or the total scale score.

The imaging also showed an increased connectivity between the insula and the posterior cingulate cortex in several frequency bands in the anxiety patients, the researchers said. “The increased connectivity observed here may be a marker of the maintenance of avoidance behaviors that characterize anxiety in PD,” they noted.

The study findings were limited by several factors including the small and unbalanced proportion of the study population with anxiety, and the consideration of global anxiety only, without distinguishing anxiety subtypes, the researchers noted. Another limitation was the use only of static EEC patterns, without using dynamic patterns, they said.

The study is the first known to use EEG to explore the mechanisms of PD-related anxiety and “the reported results provide new insights, supporting findings of previous studies using other modalities, mainly rs-fMRI, and show that EEG could be a relevant technique to explore these disorders,” the researchers wrote.

However, more research is needed to confirm the findings in patients with a larger panel of anxiety disorders, they concluded.

The study was supported by the Michael J. Fox Foundation. The researchers had no financial conflicts to disclose.

Seizure phobia stands out in epilepsy patients

Article Type
Changed

Seizure phobia occurs in nearly one-third of people with epilepsy (PWE), but was mainly associated with variables not related to epilepsy, based on data from 69 adults.

Anxiety and depression are known to affect quality of life in epilepsy patients, and previous studies have shown that anticipatory anxiety of epileptic seizures (AAS) was present in 53% of patients with focal epilepsy, wrote lead author Aviva Weiss of Psychiatric Hostels affiliated with Kidum Rehabilitation Projects, Jerusalem, and colleagues.

“Although recognized by the epilepsy and the psychiatric communities, seizure phobia as a distinct anxiety disorder among PWE is insufficiently described in the medical literature,” they said.

Seizure phobia has been defined as an anxiety disorder in which patients experience fear related to anticipation of seizures in certain situations.

In a study published in Seizure: European Journal of Epilepsy, the researchers recruited 69 PWE who were treated at an outpatient clinic. Data were collected from interviews, questionnaires, and medical records. The average age of the participants was 36.8 years, 41 were women, and 41 were married.

Overall, 19 individuals (27.5%) were diagnosed with seizure phobia. Compared with PWE without seizure phobia, the seizure phobia patients were significantly more likely to be women (84.2% vs. 44.2%; P = .005) and to have comorbid anxiety disorders (84.2% vs. 34.9%; P = .01). Individuals with seizure phobia also were significantly more likely than those without seizure phobia to have a past major depressive episode (63.2% vs. 20.9%; P = .003), and posttraumatic stress disorder (26.3% vs. 7%; P = .05).

Seizure phobia was significantly associated with comorbid psychogenic nonepileptic seizures (PNES) (36.8% vs. 11.6%; P = .034). PNES have been significantly associated with panic attacks, and “all patients with both panic attacks and comorbid PNES were diagnosed with seizure phobia,” the researchers noted. However, no significant association was found with epilepsy-related variables, they said.

A multivariate logistic regression model to predict seizure phobia showed that anxiety and a past MDE were significant predictors; the odds of seizure phobia were 10.45 times higher if a patient reported any anxiety disorder, and 6.85 times higher if the patient had a history of MDE.

The study findings were limited by several factors, including the use of semistructured interviews to diagnose seizure phobia, which are subject to interviewer bias, and by the small study population with a high proportion of comorbid PNES and epilepsy, the researchers noted. However, the results support seizure phobia as a distinct clinical entity worthy of management with education, psychosocial interventions, and potential medication changes, they said.

“Development of appropriate screening tools and implementation of effective treatment interventions is warranted for individual patients, combined with large-scale population-targeted psychoeducation, aimed to mitigate the risk of developing seizure phobia in PWE,” they concluded.

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

Early-onset severe COPD: Similar physical symptoms, but higher depression rates

Article Type
Changed

 

Younger and older patients with severe chronic obstructive pulmonary disease have similar pulmonary and physical health limitations, based on data from 1,058 adults.

Although chronic obstructive pulmonary disease (COPD) generally appears in older patients, the prevalence among adults aged 45-55 years was 6.5% in 2014-2015, wrote Rosanne J.H.C.G. Beijers, PhD, of Maastricht (the Netherlands) University Medical Center, and colleagues. However, data on the early-onset COPD phenotype are limited. In particular, the extent to which younger patients with early-onset severe COPD experienced the same physical and mental health problems as older patients with similar degree of airflow limitation has not been examined, they said.

In a study published in Clinical Nutrition, the researchers analyzed data from adults with COPD who were referred for pulmonary rehabilitation at a single center between July 2013 and August 2018. Severe disease was defined as FEV1< 50%, and early onset was defined as younger than 55 years. The mean age difference between older and younger patient groups was 15.8 years.

The study population included 79 individuals with early-onset severe disease, 54 with early-onset mild to moderate disease, 158 older adults with severe disease, and 103 older adults with mild to moderate disease. The researchers compared disease markers including body composition, physical performance, and mental health between the groups. A significantly greater proportion of the early-onset group were women, compared to the older group (64% vs. 44%).

In comparing early-onset and older patients with severe COPD, the researchers found that clinical characteristics were similar for body composition, skeletal muscle index, fat percentage, and bone mineral content, and for physical performance factors including the percent predicted maximal work capacity (Wmax), 6-minute walk test, and isokinetic strength. However, a higher prevalence of depression appeared in the early-onset severe-disease patients, compared with the older severe-disease patients (51.9% vs. 32.7%; P = .029).

Although the prevalence of depression was not based on a clinical diagnosis, this finding should prompt health care professionals to pay more attention to psychosocial and emotional well-being in early-onset severe COPD patients, the researchers noted.

In comparing early-onset severe-disease patients and early-onset patients with mild to moderate disease, patients with early-onset severe COPD had significantly lower exercise performance, based on a 6-minute walk test and percent predicted Wmax. However, body composition and isokinetic muscle strength were not significantly different between both early-onset groups.

The findings were limited by several factors including the relatively small number of early-onset patients and the lack of data on whether older patients were diagnosed with severe COPD at a younger age, and more research using age and lung function at the time of diagnosis is needed, the researchers noted. However, the results highlight the importance of early identification of patients at risk for early-onset severe COPD, they said. “Within these individuals at risk, special attention should also be paid to the development of extrapulmonary disease manifestations such as exercise limitations, impaired body composition, and psychological and emotional problems,” the researchers said. “Subsequently, intervention strategies need to be applied that not only focus on the regular advice of quitting smoking but also include decreasing the exposure to air pollutants and promoting a healthy lifestyle including physical activity and a healthy diet,” they added.

The study received no outside funding. Lead author Dr. Beijers had no financial conflicts to disclose.

Autism, ADHD linked to increased mortality risk

Article Type
Changed

All-cause mortality is significantly higher for individuals with autism spectrum disorder or attention-deficit/hyperactivity disorder than for the general population, based on data from more than 600,000 individuals.

Studies of individuals with mental disorders have suggested an increased mortality risk, compared with the general population, but similar studies of individuals with autism spectrum disorder (ASD) or ADHD have yielded inconsistent results, Ferrán Catalá-López, PhD, of the Institute of Health Carlos III, Madrid, and colleagues wrote.

In a systematic review and meta-analysis published in JAMA Pediatrics, the researchers examined 27 studies including 642,260 individuals; 154,238 with ASD and 396,488 with ADHD. The studies were published up to April 1, 2021, and included deaths from natural causes (such as respiratory illness or cancer) and unnatural (external) causes, such as accident, injury, or poisoning. The proportion of females in the studies ranged from 14% to 100%; the follow-up ranged from 3 to 33 years; and three studies included first-degree relatives.

Overall, all-cause mortality was significantly higher among individuals with ASD (rate ratio, 2.37) and ADHD (RR, 2.13), compared with the general population. Among individuals with ASD, deaths from natural causes and unnatural causes were significantly increased, compared with the general population (RR, 3.80 and RR, 2.50, respectively). Among individuals with ADHD, deaths from natural causes were not significantly increased (RR, 1.62), but deaths from unnatural causes were significantly increased, compared with the general population (RR, 2.81).

Potential mechanisms to explain the excess mortality among individuals with ASD and ADHD include health determinants and biological pathways, but the complex nature of the associations make the establishment of causality a challenge, the researchers wrote in their discussion of the findings. In general, “severe mental and behavioral disorders appear to be associated with reduced life expectancy, both in terms of mortality from external causes and mortality from other medical conditions or diseases.” With regard to ASD/ADHD in particular, these individuals often experience emotional and social problems as they enter adulthood. “Behaviors such as impulsivity and/or inattention can be contributing factors for injuries and unintentional incidents in children with ASD/ADHD,” they added.

The study findings were limited by several factors including the possible omission of studies and the use of study-level data rather than individual participant data, as well as the limitation of electronic health records, the researchers noted. Also, the studies were mostly conducted in Western countries and the results may not be generalizable to other countries.

Although ASD and ADHD were associated with a significant increased risk of all-cause mortality, “the results should be interpreted with caution because there was evidence of heterogeneity between study estimates of the mortality risks,” the researchers said. However, the results were strengthened by the large study sample, and offer a comprehensive look at the evidence supporting increased mortality risk among individuals with ASD or ADHD, and highlight the need to identify modifiable risk factors.

“Understanding the mechanisms of these associations may lead to targeted strategies to prevent avoidable deaths in high-risk groups of children and young people as an approach to improve public health,” they said.
 

 

 

Recent research support associations

The study was important because ASD and ADHD may persist into adulthood, but data from previous epidemiological studies on the impact of these disorders on mortality are inconsistent, lead author Dr. Catalá-López said in an interview.

“We conducted a systematic review and meta-analysis to evaluate all available studies of mortality associations in people with these disorders, which provide the most updated and evidence-based approach,” he explained. “Our study has only become possible in the past few years because several large population-based epidemiological studies have been available reporting similar mortality-related outcomes.”

Dr. Catalá-López said that the study findings have value in clinical practice. “We found that people with autism or attention-deficit/hyperactivity disorders would have an increased risk of mortality when compared to the general population. In our opinion, understanding the causes and mechanisms of these associations can lead to specific strategies to prevent avoidable deaths.

“Autism and attention-hyperactivity/deficit disorder are problems that can be managed with adequate and concrete programs at an early age, and most premature deaths, at least deaths from unnatural causes, can be prevented,” Dr. Catalá-López said.

“Furthermore, we believe that these results may shed some light for future research. For example, more prospective studies would be needed, particularly to examine cause-specific mortality, in larger populations of children and youth with autism/attention-deficit/hyperactivity disorder, including some of the more common comorbidities,” Dr. Catalá-López added.
 

Findings support need for screening and prevention strategies

The clear message that individuals with ASD or ADHD often die of preventable or unnatural causes demands attention and “demands widespread recognition and the implementation of systematic screening and preventive approaches,” Russell A. Barkley, PhD, of Virginia Commonwealth University, Richmond, and Geraldine Dawson, PhD, of Duke University, Durham, N.C., wrote in an accompanying editorial.

The studies included in the review also demonstrate that ADHD is associated with more than a twofold risk of early mortality in children and a more than a fourfold risk in mortality by age 45 years, they said.

The editorialists noted that the increased mortality risk may explain the ongoing conundrum among clinicians as to why the prevalence of ADHD seems to decline with age, “such that 5%-8% of children may meet diagnostic criteria for ADHD while that figure falls to 4%-5% of adults and 2%-3% of older adults,” despite evidence that a majority of childhood cases will be rediagnosed in adulthood. However, the current study offers an alternative. “This systematic review and meta-analysis and the studies included within it make plain that another explanation is the greater loss of individuals with these conditions from the population over time owing to heightened mortality, compared with typical peers,” they said.

“In addition to ADHD diagnosis, ASD diagnosis is also associated with other psychiatric comorbidities that are correlated with increased risk for mortality, including anxiety and affective disorders,” the editorialists noted. Other considerations for increased mortality among individuals with ASD include different protective and risk factors associated with suicide risk, compared with the general population, as well as poorer social and daily living skills compared to the general population.

The study findings “argue for individuals with ADHD and individuals with ASD being viewed through a public health lens with screening and prevention strategies offered beginning in early childhood. These findings should also give impetus to efforts to try to reduce the first order risk factors that are predisposing to reduced life expectancy, such as obesity, substance use, poor diet, poor sleep, and limited exercise among children and adults with ASD and ADHD,” they said.

“A preventive strategy would necessitate primary care physicians becoming more aware of the linkage between both ASD diagnosis and ADHD diagnosis and early mortality as well as their link to reduced [estimated life expectancy],” and such an approach could potentially reduce the higher mortality risk identified in the current review, they concluded.

All-cause mortality is significantly higher for individuals with autism spectrum disorder or attention-deficit/hyperactivity disorder than for the general population, based on data from more than 600,000 individuals.

Studies of individuals with mental disorders have suggested an increased mortality risk, compared with the general population, but similar studies of individuals with autism spectrum disorder (ASD) or ADHD have yielded inconsistent results, Ferrán Catalá-López, PhD, of the Institute of Health Carlos III, Madrid, and colleagues wrote.

In a systematic review and meta-analysis published in JAMA Pediatrics, the researchers examined 27 studies including 642,260 individuals; 154,238 with ASD and 396,488 with ADHD. The studies were published up to April 1, 2021, and included deaths from natural causes (such as respiratory illness or cancer) and unnatural (external) causes, such as accident, injury, or poisoning. The proportion of females in the studies ranged from 14% to 100%; the follow-up ranged from 3 to 33 years; and three studies included first-degree relatives.

Overall, all-cause mortality was significantly higher among individuals with ASD (rate ratio, 2.37) and ADHD (RR, 2.13), compared with the general population. Among individuals with ASD, deaths from natural causes and unnatural causes were significantly increased, compared with the general population (RR, 3.80 and RR, 2.50, respectively). Among individuals with ADHD, deaths from natural causes were not significantly increased (RR, 1.62), but deaths from unnatural causes were significantly increased, compared with the general population (RR, 2.81).

Potential mechanisms to explain the excess mortality among individuals with ASD and ADHD include health determinants and biological pathways, but the complex nature of the associations make the establishment of causality a challenge, the researchers wrote in their discussion of the findings. In general, “severe mental and behavioral disorders appear to be associated with reduced life expectancy, both in terms of mortality from external causes and mortality from other medical conditions or diseases.” With regard to ASD/ADHD in particular, these individuals often experience emotional and social problems as they enter adulthood. “Behaviors such as impulsivity and/or inattention can be contributing factors for injuries and unintentional incidents in children with ASD/ADHD,” they added.

The study findings were limited by several factors including the possible omission of studies and the use of study-level data rather than individual participant data, as well as the limitation of electronic health records, the researchers noted. Also, the studies were mostly conducted in Western countries and the results may not be generalizable to other countries.

Although ASD and ADHD were associated with a significant increased risk of all-cause mortality, “the results should be interpreted with caution because there was evidence of heterogeneity between study estimates of the mortality risks,” the researchers said. However, the results were strengthened by the large study sample, and offer a comprehensive look at the evidence supporting increased mortality risk among individuals with ASD or ADHD, and highlight the need to identify modifiable risk factors.

“Understanding the mechanisms of these associations may lead to targeted strategies to prevent avoidable deaths in high-risk groups of children and young people as an approach to improve public health,” they said.
 

 

 

Recent research support associations

The study was important because ASD and ADHD may persist into adulthood, but data from previous epidemiological studies on the impact of these disorders on mortality are inconsistent, lead author Dr. Catalá-López said in an interview.

“We conducted a systematic review and meta-analysis to evaluate all available studies of mortality associations in people with these disorders, which provide the most updated and evidence-based approach,” he explained. “Our study has only become possible in the past few years because several large population-based epidemiological studies have been available reporting similar mortality-related outcomes.”

Dr. Catalá-López said that the study findings have value in clinical practice. “We found that people with autism or attention-deficit/hyperactivity disorders would have an increased risk of mortality when compared to the general population. In our opinion, understanding the causes and mechanisms of these associations can lead to specific strategies to prevent avoidable deaths.

“Autism and attention-hyperactivity/deficit disorder are problems that can be managed with adequate and concrete programs at an early age, and most premature deaths, at least deaths from unnatural causes, can be prevented,” Dr. Catalá-López said.

“Furthermore, we believe that these results may shed some light for future research. For example, more prospective studies would be needed, particularly to examine cause-specific mortality, in larger populations of children and youth with autism/attention-deficit/hyperactivity disorder, including some of the more common comorbidities,” Dr. Catalá-López added.
 

Findings support need for screening and prevention strategies

The clear message that individuals with ASD or ADHD often die of preventable or unnatural causes demands attention and “demands widespread recognition and the implementation of systematic screening and preventive approaches,” Russell A. Barkley, PhD, of Virginia Commonwealth University, Richmond, and Geraldine Dawson, PhD, of Duke University, Durham, N.C., wrote in an accompanying editorial.

The studies included in the review also demonstrate that ADHD is associated with more than a twofold risk of early mortality in children and a more than a fourfold risk in mortality by age 45 years, they said.

The editorialists noted that the increased mortality risk may explain the ongoing conundrum among clinicians as to why the prevalence of ADHD seems to decline with age, “such that 5%-8% of children may meet diagnostic criteria for ADHD while that figure falls to 4%-5% of adults and 2%-3% of older adults,” despite evidence that a majority of childhood cases will be rediagnosed in adulthood. However, the current study offers an alternative. “This systematic review and meta-analysis and the studies included within it make plain that another explanation is the greater loss of individuals with these conditions from the population over time owing to heightened mortality, compared with typical peers,” they said.

“In addition to ADHD diagnosis, ASD diagnosis is also associated with other psychiatric comorbidities that are correlated with increased risk for mortality, including anxiety and affective disorders,” the editorialists noted. Other considerations for increased mortality among individuals with ASD include different protective and risk factors associated with suicide risk, compared with the general population, as well as poorer social and daily living skills compared to the general population.

Clinical data affirm dupilumab for chronic nasal polyps

Article Type
Changed

In a specialty clinic, dupilumab (Dupixent) injections significantly improved symptoms for patients with chronic rhinosinusitis with nasal polyps, based on provisional data from more than 100 adults.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a significant burden among working-age adults. Symptom control remains a challenge for many of these patients, and the cost in lost productivity and health care consumption can be substantial, write Rik J.L. van der Lans, MD, of the University of Amsterdam, and colleagues.

Dupilumab, a biologic that targets components of the type 2 inflammatory pathway, represents a new option that has shown effectiveness in clinical trials for regulatory approval, they said.

A new observational study tests dupilumab in patients who met criteria for biological treatment proposed in a recent major systematic review. The findings were published in the journal Allergy.

In the study, the researchers identified 131 adults older than 18 years (mean age 51.7) with CRSwNP treated at a single tertiary care center. Participants received 300 mg of dupilumab subcutaneous injection every 2 weeks for at least 12 weeks.

The primary outcomes were scores on several measures, including the SinoNasal Outcome Test-22 (SNOT-22, scale of 0-110), the bilateral Nasal Polyp Score (NPS, scale of 0-8), and the Sniffin’ Sticks-12 identification test (SSIT-12, scale of 0-6 anosmia, 7-10 hyposmia, 11-12 normosmia).

The mean scores on all three outcomes improved significantly from baseline to both 24 weeks and 48 weeks. Scores on the SNOT-22 improved from 52.4 at baseline to 18.5 and 16.8 at weeks 24 and 48, respectively. NPS improved from 5.4 at baseline to 1.6 and 1.0, respectively. SSIT-12 scores improved from 3.6 at baseline to 7.3 and 8.3, respectively.

At baseline, 95.8% of the patients had uncontrolled chronic rhinosinusitis, but at 24 and 48 weeks, respectively, 24.3% and 6.2% were uncontrolled.

Approximately half of the patients experienced treatment-emergent adverse events, but these were “mild and decreased in occurrence and intensity throughout treatment,” the researchers say.

For patients with a strong response, the researchers also tested an extension of the interval between doses to 4 weeks and 6 weeks, in a provisional indication of continued established control at these timepoints.

The study findings were limited by several factors, including the potential for selection bias, and data from only the first patient cohort, the researchers noted. However, the results were strengthened by the real-life context, standardized indications, and long-term follow up for almost a year, they said.

More research is needed on nonacademic patient cohorts, but the current data confirm the effectiveness of dupilumab as an add-on for difficult-to-treat CRSwNP, they concluded. The findings also validate the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS2020) inclusion criteria for biologic treatment, they said.

The new study is important because of the need for verification of results from randomized controlled trials using real-world data, Dr. Van der Lans told this news organization.

“For example, differences in treatment efficacy might result from differing indication criteria, and the inclusion/exclusion criteria in the RCTs might have excluded patients one would encounter in daily practice,” he said. “With our prospective observational cohort, we are seeking to verify efficacy, monitor pharmacovigilance, and evaluate and advance the indication criteria and positioning of biologicals registered for CRSwNP, such as dupilumab.”

These cross-sectional results suggest dupilumab is more effective in preventing possibly harmful escape treatments, such as oral corticosteroids and/or surgery, than reported by the registration trials.

“Additionally, it appears possible to maintain established CRS-control during response-dependent, stepwise, interdose interval prolongation of up to 6 weeks, which is officially an off-label dosing interval,” he said. “This would greatly benefit patients’ treatment burden and direct costs,” he said. However, both findings require corroboration by anticipated longitudinal results in 2022, he noted.

The key message for clinicians in practice: “Biologicals like dupilumab are a potent and promising treatment for severe CRSwNP when conventional medical and surgical therapy fails,” he emphasized.

Looking ahead, important research objectives include head-on comparison studies of the diverse biological agents, establishing biomarkers to guide preferential therapy, and evaluating the economics of biologics compared with conventional therapy, Dr. Van der Lans added. Such research is vital not only for improving patient-centered care but to sustain the use of biologicals in a health-economic perspective.

One of the greatest criticisms of biologic therapy for CRSwNP is cost, particularly in a setting of ever-increasing health care costs. A recent review noted the average cost per year is greater than $30,000.
 

 

 

Real-life study verifies effectiveness

“As the authors pointed out, this is a real-life, prospective observational cohort with a decently large size, evaluating the therapeutic efficacy of add-on dupilumab,” said Seong H. Cho, MD, of the University of South Florida, Tampa, in an interview.

“Dupilumab is the first FDA-approved biologic to treat severe chronic rhinosinusitis with nasal polyps based on two phase 3 clinical trials,” said Dr. Cho, who was not involved with the study. “It has been more than 2 years since dupilumab was approved for severe CRSwNP by the FDA and EMA. This real-life, prospective, observational study with a decent size verified the efficacy of dupilumab as an add-on treatment when used with a proper indication such as EPOS2020 indication criteria.

“I am not surprised by the efficacy of dupilumab on severe CRSwNP, based on my clinical experience. My clinical observation is similar to the results of this study. This study verifies that dupilumab is highly efficacious in treating refractory and severe CRSwNP in a real-life setting by improving all subjective and objective clinical outcomes such as SNOT-22, NPS, and smell test score,” he said. The study also confirms that a stepwise, interdose interval prolongation from every 2-4 weeks for CRSwNP patients with good response should be a consideration for clinical practice, he added. 

The cost-effectiveness of dupilumab is the main barrier to more consistent use, Dr. Cho said. “There is no evidence that dupilumab can change the course of the disease, and we don’t know how long patients need to be on this drug. Therefore, nasal polyps need to be refractory and severe enough to use dupilumab and other biologics,” he explained.

Consequently, proper indication criteria, such as the EPOS2020 indication criteria for biologics, should be established before initiating dupilumab, Dr. Cho noted.

“Generally, endoscopic sinus surgery would be preferred in sinus-surgery naive CRSwNP patients, unless surgery is contraindicated or refused by patients because of cost-effectiveness rather than the superior efficacy,” he said. “If surgery fails, then dupilumab can be considered. In addition, proper evaluation of nasal polyp severity would be important.”

“One should establish an objective NPS by endoscopic exam before initiation of dupilumab. This baseline score would be an important marker to assess the efficacy of dupilumab in the course of treatment.”

Monitoring of the NPS together with the patient’s symptom improvement would be essential to implementing a stepwise, interdose interval prolongation to reduce the cost, he emphasized. 

“The most crucial additional research is establishing suitable biomarkers for the response of dupilumab and other biologics,” said Dr. Cho. “Overall, the performance of dupilumab seems to be good. But there are patients unresponsive to dupilumab, even more to other recently FDA-approved biologics for CRSwNP.”

Blood eosinophils and exhaled nitric oxide can be a good biomarker for type 2 asthma, Dr. Cho added. “Still, there is no evidence that these biomarkers are decent for CRSwNP, even though CRSwNP is mostly considered as type 2 disease. Therefore, it would be essential to find promising biomarkers for severe CRSwNP.”

Dr. Van der Lans disclosed serving as a consultant for GlaxoSmithKline, and several coauthors disclosed relationships with companies including Sanofi and Novartis. The patient registry from which the study population was drawn is cofunded by Sanofi and Novartis. Dr. Cho has disclosed no relevant financial relationships.

Symptom control remains a challenge for many of these patients, and the cost in lost productivity and health care consumption can be substantial, write Rik J.L. van der Lans, MD, of the University of Amsterdam, and colleagues.

Dupilumab, a biologic that targets components of the type 2 inflammatory pathway, represents a new option that has shown effectiveness in clinical trials for regulatory approval, they said.

A new observational study tests dupilumab in patients who met criteria for biological treatment proposed in a recent major systematic review. The findings were published in the journal Allergy.

In the study, the researchers identified 131 adults older than 18 years (mean age 51.7) with CRSwNP treated at a single tertiary care center. Participants received 300 mg of dupilumab subcutaneous injection every 2 weeks for at least 12 weeks.

The primary outcomes were scores on several measures, including the SinoNasal Outcome Test-22 (SNOT-22, scale of 0-110), the bilateral Nasal Polyp Score (NPS, scale of 0-8), and the Sniffin’ Sticks-12 identification test (SSIT-12, scale of 0-6 anosmia, 7-10 hyposmia, 11-12 normosmia).

The mean scores on all three outcomes improved significantly from baseline to both 24 weeks and 48 weeks. Scores on the SNOT-22 improved from 52.4 at baseline to 18.5 and 16.8 at weeks 24 and 48, respectively. NPS improved from 5.4 at baseline to 1.6 and 1.0, respectively. SSIT-12 scores improved from 3.6 at baseline to 7.3 and 8.3, respectively.

At baseline, 95.8% of the patients had uncontrolled chronic rhinosinusitis, but at 24 and 48 weeks, respectively, 24.3% and 6.2% were uncontrolled.

Approximately half of the patients experienced treatment-emergent adverse events, but these were “mild and decreased in occurrence and intensity throughout treatment,” the researchers say.

For patients with a strong response, the researchers also tested an extension of the interval between doses to 4 weeks and 6 weeks, in a provisional indication of continued established control at these timepoints.

The study findings were limited by several factors, including the potential for selection bias, and data from only the first patient cohort, the researchers noted. However, the results were strengthened by the real-life context, standardized indications, and long-term follow up for almost a year, they said.

More research is needed on nonacademic patient cohorts, but the current data confirm the effectiveness of dupilumab as an add-on for difficult-to-treat CRSwNP, they concluded. The findings also validate the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS2020) inclusion criteria for biologic treatment, they said.

The new study is important because of the need for verification of results from randomized controlled trials using real-world data, Dr. Van der Lans told this news organization.

“For example, differences in treatment efficacy might result from differing indication criteria, and the inclusion/exclusion criteria in the RCTs might have excluded patients one would encounter in daily practice,” he said. “With our prospective observational cohort, we are seeking to verify efficacy, monitor pharmacovigilance, and evaluate and advance the indication criteria and positioning of biologicals registered for CRSwNP, such as dupilumab.”

These cross-sectional results suggest dupilumab is more effective in preventing possibly harmful escape treatments, such as oral corticosteroids and/or surgery, than reported by the registration trials.

“Additionally, it appears possible to maintain established CRS-control during response-dependent, stepwise, interdose interval prolongation of up to 6 weeks, which is officially an off-label dosing interval,” he said. “This would greatly benefit patients’ treatment burden and direct costs,” he said. However, both findings require corroboration by anticipated longitudinal results in 2022, he noted.

The key message for clinicians in practice: “Biologicals like dupilumab are a potent and promising treatment for severe CRSwNP when conventional medical and surgical therapy fails,” he emphasized.

Looking ahead, important research objectives include head-on comparison studies of the diverse biological agents, establishing biomarkers to guide preferential therapy, and evaluating the economics of biologics compared with conventional therapy, Dr. Van der Lans added. Such research is vital not only for improving patient-centered care but to sustain the use of biologicals in a health-economic perspective.

One of the greatest criticisms of biologic therapy for CRSwNP is cost, particularly in a setting of ever-increasing health care costs. A recent review noted the average cost per year is greater than $30,000.
 

 

 

Real-life study verifies effectiveness

“As the authors pointed out, this is a real-life, prospective observational cohort with a decently large size, evaluating the therapeutic efficacy of add-on dupilumab,” said Seong H. Cho, MD, of the University of South Florida, Tampa, in an interview.

“Dupilumab is the first FDA-approved biologic to treat severe chronic rhinosinusitis with nasal polyps based on two phase 3 clinical trials,” said Dr. Cho, who was not involved with the study. “It has been more than 2 years since dupilumab was approved for severe CRSwNP by the FDA and EMA. This real-life, prospective, observational study with a decent size verified the efficacy of dupilumab as an add-on treatment when used with a proper indication such as EPOS2020 indication criteria.

“I am not surprised by the efficacy of dupilumab on severe CRSwNP, based on my clinical experience. My clinical observation is similar to the results of this study. This study verifies that dupilumab is highly efficacious in treating refractory and severe CRSwNP in a real-life setting by improving all subjective and objective clinical outcomes such as SNOT-22, NPS, and smell test score,” he said. The study also confirms that a stepwise, interdose interval prolongation from every 2-4 weeks for CRSwNP patients with good response should be a consideration for clinical practice, he added. 

The cost-effectiveness of dupilumab is the main barrier to more consistent use, Dr. Cho said. “There is no evidence that dupilumab can change the course of the disease, and we don’t know how long patients need to be on this drug. Therefore, nasal polyps need to be refractory and severe enough to use dupilumab and other biologics,” he explained.

Consequently, proper indication criteria, such as the EPOS2020 indication criteria for biologics, should be established before initiating dupilumab, Dr. Cho noted.

“Generally, endoscopic sinus surgery would be preferred in sinus-surgery naive CRSwNP patients, unless surgery is contraindicated or refused by patients because of cost-effectiveness rather than the superior efficacy,” he said. “If surgery fails, then dupilumab can be considered. In addition, proper evaluation of nasal polyp severity would be important.”

“One should establish an objective NPS by endoscopic exam before initiation of dupilumab. This baseline score would be an important marker to assess the efficacy of dupilumab in the course of treatment.”

Monitoring of the NPS together with the patient’s symptom improvement would be essential to implementing a stepwise, interdose interval prolongation to reduce the cost, he emphasized. 

“The most crucial additional research is establishing suitable biomarkers for the response of dupilumab and other biologics,” said Dr. Cho. “Overall, the performance of dupilumab seems to be good. But there are patients unresponsive to dupilumab, even more to other recently FDA-approved biologics for CRSwNP.”

Blood eosinophils and exhaled nitric oxide can be a good biomarker for type 2 asthma, Dr. Cho added. “Still, there is no evidence that these biomarkers are decent for CRSwNP, even though CRSwNP is mostly considered as type 2 disease. Therefore, it would be essential to find promising biomarkers for severe CRSwNP.”

Dr. Van der Lans disclosed serving as a consultant for GlaxoSmithKline, and several coauthors disclosed relationships with companies including Sanofi and Novartis. The patient registry from which the study population was drawn is cofunded by Sanofi and Novartis. Dr. Cho has disclosed no relevant financial relationships.

Restless legs syndrome surged early during pandemic

Article Type
Changed

Individuals with restless legs syndrome showed an increase in symptom severity in the early phase of the COVID-19 pandemic in the United States in 2020, but this increase had waned by 2021, according to data from 500 participants in the National Restless Legs Syndrome Opioid Registry.

Sufferers of restless legs syndrome (RLS) experience not only sleep disturbance, but also daytime sleepiness, and high levels of depression, anxiety, and panic, wrote Benjamin Wipper of Harvard Medical School, Boston, and colleagues.

“Considering the link between RLS and psychiatric illness, it has been speculated that there may have been increases in RLS symptom severity alongside the recent rise in depression and anxiety,” but this association has not been explored, they said.

In a study published in Sleep Medicine , the researchers reviewed data from 500 adult participants in the National RLS Opioid Registry, a longitudinal observational study. Participants reported RLS symptom severity before and during the COVID-19 pandemic at 6-month intervals. Survey responses were collected from the early phase of the pandemic in the United States in January/February 2020, then in April/May 2020, and then 6 months later, from September 2020 through February 2021, and also 1 year later, in March 2021 through June 2021.

Participants completed a baseline phone interview and online survey, with symptoms assessed via the International Restless Legs Syndrome Study Group severity scale (IRLS), the Insomnia Severity Index (ISI), the General Anxiety Disorder-7 scale (GAD-7), and the Patient Health Questionnaire (PHQ-9).

In all, 153 participants completed surveys during January and February 2020, and 155 completed surveys during April and May 2020. Baseline characteristics were similar for all participants.

In a between-subjects analysis for these time periods, symptom scores on the IRLS were significantly higher in January/February 2020; participants were approximately twice as likely to have IRLS scores of 20 or higher compared to April/May 2020 (37.7% vs. 20.9%).

The researchers also compared responses by the same participants at baseline and 6 months later, from September 2020 through February 2021, and 1 year later, from March 2021 through June 2021. In this within-subjects analysis, 51.3% of the participants had increased IRLS scores in spring 2020. Participants were significantly more likely to have IRLS scores of 20 or above in the early COVID-19 period in April and May 2020 compared with baseline (37.7% vs. 26.6%). Both PHQ-9 and GAD-7 scores were higher during early COVID-19 in April and May 2020 than at baseline.

“Changes in IRLS were also significantly correlated with changes in both PHQ-9 and GAD-7 scores, providing further support for the associations of RLS to both depression and anxiety,” the researchers wrote. “Notably, individuals who completed surveys in January and February 2020 did not see increases in RLS severity or other mental health questionnaire values on subsequent six-month surveys completed during the pandemic or on the following iteration of surveys 1 year later. We suspect that these findings may be at least partially related to the timing of the surveys,” the researchers said. Six-month survey data for most patients were collected during a decline in cases and hospitalizations, and 1-year data in early 2021 may have reflected optimism with the availability of vaccines, they said. 

The study findings were limited by several factors including the observational design, which prevented conclusions about causality, and the lack of data on the effect of COVID-19 infection on RLS symptoms, which should be investigated in future studies, the researchers said.

However, the results are the first evidence of increased RLS symptom severity during the COVID-19 pandemic, and elevated scores were associated with sleep disturbance, depression, and anxiety, they wrote. “These data suggest that clinicians should attend to RLS symptoms during the current pandemic and in future instances of socioeconomic and/or political uncertainty. Future studies need to confirm these findings in other populations of patients with RLS,” they concluded.

The National RLS Opioid Registry has received research funding from the RLS Foundation, the Baszucki Brain Research Fund, Florence Petrlik Family Foundation, Diane and Richard Brainerd, Steven Silin, and Jerry Blakeley. The researchers had no financial conflicts to disclose.

Biomarkers predict cardiovascular risk in chronic kidney disease patients

Article Type
Changed

Models using novel kidney and cardiac biomarkers were the most effective predictors of 10-year risk for atherosclerotic cardiovascular disease in chronic kidney disease patients, in a new study.

Chronic kidney disease (CKD) patients may be at increased risk for atherosclerotic cardiovascular disease, but no ASCVD risk prediction models are currently in place to inform clinical care and prevention strategies, Joshua Bundy, PhD, of Tulane University, New Orleans, and colleagues wrote in their paper, published in the Journal of the American Society of Nephrology.

Dr. Joshua Bundy

To improve the accuracy of ASCVD risk prediction, the researchers developed several models using data from the Chronic Renal Insufficiency Cohort (CRIC) study. This longitudinal cohort study included more than 2,500 adult CKD patients. The participants’ ages ranged from 21-74 years, with the mean age having been 55.8 years, and 52.0% of the cohort was male.

Kidney function was defined using the glomerular filtration rate; the mean estimated glomerular filtration rate (eGFR) of the study participants was 56.0 mL/min per 1.73m2. The primary endpoint for the prediction models was incident ASCVD, defined as a composite of incident fatal or nonfatal stroke or MI.

A total of 252 incident ASCVD events occurred during the first 10 years of follow-up from baseline (1.9 events per 1,000 person-years). Patients with ASCVD events were more likely to be older, Black, and current smokers. They also were more likely than those who did not experience ASCVD events to have less than a college level education, to have a history of diabetes, and to use blood pressure–lowering medications.

“In our study, we created two new prediction tools for patients with CKD: the first is a simple model that includes factors routinely measured by health care providers and the second is an expanded model with additional variables particularly important to patients with CKD, including measures of long-term blood sugar, inflammation, and kidney and heart injury,” he explained. “We found that the new models are better able to classify patients who will or will not have a stroke or heart attack within 10 years, compared with the standard models. The new tools may better assist health care providers and patients with CKD in shared decision-making for prevention of heart disease.”
 

Results

The area under the curve for a prediction model using coefficients estimated within the CRIC sample was 0.736. This represented an accuracy higher than the American College of Cardiology/American Heart Association Pooled Cohort Equations (PCE), which have shown an AUC of 0.730 (P = .03). The PCE were developed by the ACC and the AHA in 2013 to estimate ASCVD risk in the primary prevention population.

The second CRIC model that was developed using clinically available variables had an AUC of 0.760. However, the third CRIC biomarker-enriched model was even more effective, with an AUC of 0.771 – significantly higher than the clinical model (P = .001).

Model 1 included the ACC/AHA PCE variables with coefficients recalculated in the CRIC study sample. Model 2 (the CRIC Clinical Model) included age, HDL cholesterol, systolic BP, current smoking, urinary albumin-to-creatinine ratio (ACR), hemoglobin A1c, and hemoglobin. Model 3 (the CRIC Enriched Model) included age, total cholesterol, HDL cholesterol, current smoking, urinary ACR, A1c, apolipoprotein B, high-sensitivity C-reactive protein (hsCRP), troponin T, and N-terminal of the prohormone brain natriuretic peptide (NT-proBNP).

Both the clinical and biomarker models improved reclassification of non-ASCVD events, compared with the PCEs (6.6% and 10.0%, respectively).

Several factors not included in prior prediction models were important for atherosclerotic CVD prediction among patients with CKD, the researchers noted. These included variables routinely measured in clinical practice as well as biomarkers: measures of long-term glycemia (A1c), inflammation (hsCRP), kidney injury (urinary ACR), and cardiac injury (troponin T and NT-proBNP).

Patients who had an ASCVD event had higher levels of A1c, systolic and diastolic BP, urinary ACR, troponin T, and NT-proBNP; these patients also had lower levels of HDL cholesterol, eGFR, and hemoglobin, compared with those who did not have an event.

The study findings were limited by several factors including the selection of study participants based on a single assessment of kidney function, who had an above average baseline ASCVD risk, the researchers noted. Other limitations included the inability to include imaging variables in the models, and the overestimated risk in the highest predicted probability groups in the CRIC study.

However, the models significantly improve prediction beyond the ACC/AHA PCE in patients with CKD, they concluded.

 

 

 

Models may inform shared decision-making

The development of new prediction models is important, because cardiovascular disease is the leading cause of death among U.S. adults and preventing CVD is a major public health challenge, lead author Dr. Bundy said in an interview.

“In an effort to prevent CVD, risk prediction equations can help identify patients who are at high risk for developing CVD and who may benefit from initiation or intensification of preventive and/or therapeutic measures. Simultaneously, chronic kidney disease is prevalent and those with CKD are often considered at high risk for CVD,” he said.

“However, common risk prediction tools were developed for the general population and may not work as well in patients with CKD, who may have different risk factors. Improving risk prediction in patients with CKD may help identify those among this growing population who are truly at high risk, as well as identify those who are at low risk and less likely to benefit from invasive procedures,” Dr. Bundy explained.
 

Glomerular filtration rate was not a strong predictor of atherosclerotic CVD

“One of the surprising findings was that estimated glomerular filtration rate was not a strong predictor and was not included in our final models,” Dr. Bundy said.

“We know that eGFR is a very important measurement in this population, but our results suggest that, at least in our sample, urinary albumin-to-creatinine ratio and cardiac biomarkers like troponin T and NT-proBNP are stronger predictors of atherosclerotic CVD in a population with reduced kidney function,” he said.

“Patient characteristics like age, blood pressure, and cholesterol are used by health care providers to predict whether a person will have a heart attack or stroke. However, most currently available prediction tools were not made for use in patients with CKD, which is a condition that is becoming more common and is likely to be seen by more health care providers in family practice,” said Dr. Bundy. “These people with CKD may have different risk factors for heart disease.”
 

Models are useful for clinical practice

“We are seeing rising numbers of patients with CKD in the population because of increasing age, rising rates of diabetes, and hypertension,” Noel Deep, MD, said in an interview. “The current practice of medicine does not have CKD-specific prediction models for ASCVD development, and current risks are calculated based on prediction models developed for the general population.”

“Having a prediction model that incorporates criteria/variables associated with CKD improves our ability to accurately identify and address the risk of ASCVD in this particular patient population,” said Dr. Deep, who is a general internist in a multispecialty group practice with Aspirus Antigo (Wisc.) Clinic and the chief medical officer and a staff physician at Aspirus Langlade Hospital, also in Antigo.

“We always knew that CKD does place the individual at higher risk for developing ASCVD, but I was impressed by the significant improvement in the prediction models using CKD specific tools, such as cardiac biomarkers (NT-proBNP), intensity of diabetes control (A1c), tobacco use, urinary albuminuria, in addition to advancing age,” he said. “Many of the laboratory tests listed in this study are commonly available and can be easily incorporated into our evaluation for and management of ASCVD in our patients with CKD.”

“As a practicing primary care physician, I would say that this study emphasizes the importance of identifying and working toward mitigating the associated health risks that our patients with CKD might have coexisting and that significantly contribute to progression of CKD,” said Dr. Deep, who is also assistant clinical professor at the Medical College of Wisconsin, Wausau. “By addressing these risk factors, we can positively impact the health of our patients with CKD and decrease the morbidity and mortality, and health care costs. These predictive models can hopefully help us more accurately identify the risk of ASCVD thereby decreasing unnecessary diagnostic procedures and interventions which carry their own risks and morbidity.”

Looking ahead, “these predictive models should be assessed and validated in large studies in diverse populations and those with different risk factors for ASCVD because CKD can be caused by several different medical conditions each with potential to contribute to ASCVD,” Dr. Deep added.
 

 

 

Limitations and next steps

“Although we externally validated our models in two population-based cohort studies, the individuals in these datasets were selected based on only one assessment of kidney function,” Dr. Bundy noted. “Furthermore, the best practices for implementing risk prediction models in the clinic remain to be determined, especially as new models are developed.

“While our models show promising performance for predicting 10-year risk of atherosclerotic CVD, more clinical trials are needed to test implementation of these models for improving patient care and disease prevention.”

The new tools may better assist health care providers and patients with CKD in shared decision-making for prevention of heart disease.”
 

Results

The area under the curve for a prediction model using coefficients estimated within the CRIC sample was 0.736. This represented an accuracy higher than the American College of Cardiology/American Heart Association Pooled Cohort Equations (PCE), which have shown an AUC of 0.730 (P = .03). The PCE were developed by the ACC and the AHA in 2013 to estimate ASCVD risk in the primary prevention population.

The second CRIC model that was developed using clinically available variables had an AUC of 0.760. However, the third CRIC biomarker-enriched model was even more effective, with an AUC of 0.771 – significantly higher than the clinical model (P = .001).

Model 1 included the ACC/AHA PCE variables with coefficients recalculated in the CRIC study sample. Model 2 (the CRIC Clinical Model) included age, HDL cholesterol, systolic BP, current smoking, urinary albumin-to-creatinine ratio (ACR), hemoglobin A1c, and hemoglobin. Model 3 (the CRIC Enriched Model) included age, total cholesterol, HDL cholesterol, current smoking, urinary ACR, A1c, apolipoprotein B, high-sensitivity C-reactive protein (hsCRP), troponin T, and N-terminal of the prohormone brain natriuretic peptide (NT-proBNP).

Both the clinical and biomarker models improved reclassification of non-ASCVD events, compared with the PCEs (6.6% and 10.0%, respectively).

Several factors not included in prior prediction models were important for atherosclerotic CVD prediction among patients with CKD, the researchers noted. These included variables routinely measured in clinical practice as well as biomarkers: measures of long-term glycemia (A1c), inflammation (hsCRP), kidney injury (urinary ACR), and cardiac injury (troponin T and NT-proBNP).

Patients who had an ASCVD event had higher levels of A1c, systolic and diastolic BP, urinary ACR, troponin T, and NT-proBNP; these patients also had lower levels of HDL cholesterol, eGFR, and hemoglobin, compared with those who did not have an event.

The study findings were limited by several factors including the selection of study participants based on a single assessment of kidney function, who had an above average baseline ASCVD risk, the researchers noted. Other limitations included the inability to include imaging variables in the models, and the overestimated risk in the highest predicted probability groups in the CRIC study.

However, the models significantly improve prediction beyond the ACC/AHA PCE in patients with CKD, they concluded.

 

 

 

Models may inform shared decision-making

The development of new prediction models is important, because cardiovascular disease is the leading cause of death among U.S. adults and preventing CVD is a major public health challenge, lead author Dr. Bundy said in an interview.

“In an effort to prevent CVD, risk prediction equations can help identify patients who are at high risk for developing CVD and who may benefit from initiation or intensification of preventive and/or therapeutic measures. Simultaneously, chronic kidney disease is prevalent and those with CKD are often considered at high risk for CVD,” he said.

“However, common risk prediction tools were developed for the general population and may not work as well in patients with CKD, who may have different risk factors. Improving risk prediction in patients with CKD may help identify those among this growing population who are truly at high risk, as well as identify those who are at low risk and less likely to benefit from invasive procedures,” Dr. Bundy explained.
 

Glomerular filtration rate was not a strong predictor of atherosclerotic CVD

“One of the surprising findings was that estimated glomerular filtration rate was not a strong predictor and was not included in our final models,” Dr. Bundy said.

“We know that eGFR is a very important measurement in this population, but our results suggest that, at least in our sample, urinary albumin-to-creatinine ratio and cardiac biomarkers like troponin T and NT-proBNP are stronger predictors of atherosclerotic CVD in a population with reduced kidney function,” he said.

“Patient characteristics like age, blood pressure, and cholesterol are used by health care providers to predict whether a person will have a heart attack or stroke. However, most currently available prediction tools were not made for use in patients with CKD, which is a condition that is becoming more common and is likely to be seen by more health care providers in family practice,” said Dr. Bundy. “These people with CKD may have different risk factors for heart disease.”
 

Models are useful for clinical practice

“We are seeing rising numbers of patients with CKD in the population because of increasing age, rising rates of diabetes, and hypertension,” Noel Deep, MD, said in an interview. “The current practice of medicine does not have CKD-specific prediction models for ASCVD development, and current risks are calculated based on prediction models developed for the general population.”

“Having a prediction model that incorporates criteria/variables associated with CKD improves our ability to accurately identify and address the risk of ASCVD in this particular patient population,” said Dr. Deep, who is a general internist in a multispecialty group practice with Aspirus Antigo (Wisc.) Clinic and the chief medical officer and a staff physician at Aspirus Langlade Hospital, also in Antigo.

“We always knew that CKD does place the individual at higher risk for developing ASCVD, but I was impressed by the significant improvement in the prediction models using CKD specific tools, such as cardiac biomarkers (NT-proBNP), intensity of diabetes control (A1c), tobacco use, urinary albuminuria, in addition to advancing age,” he said. “Many of the laboratory tests listed in this study are commonly available and can be easily incorporated into our evaluation for and management of ASCVD in our patients with CKD.”

“As a practicing primary care physician, I would say that this study emphasizes the importance of identifying and working toward mitigating the associated health risks that our patients with CKD might have coexisting and that significantly contribute to progression of CKD,” said Dr. Deep, who is also assistant clinical professor at the Medical College of Wisconsin, Wausau. “By addressing these risk factors, we can positively impact the health of our patients with CKD and decrease the morbidity and mortality, and health care costs. These predictive models can hopefully help us more accurately identify the risk of ASCVD thereby decreasing unnecessary diagnostic procedures and interventions which carry their own risks and morbidity.”

Looking ahead, “these predictive models should be assessed and validated in large studies in diverse populations and those with different risk factors for ASCVD because CKD can be caused by several different medical conditions each with potential to contribute to ASCVD,” Dr. Deep added.
 

 

 

Limitations and next steps

“Although we externally validated our models in two population-based cohort studies, the individuals in these datasets were selected based on only one assessment of kidney function,” Dr. Bundy noted. “Furthermore, the best practices for implementing risk prediction models in the clinic remain to be determined, especially as new models are developed.

“While our models show promising performance for predicting 10-year risk of atherosclerotic CVD, more clinical trials are needed to test implementation of these models for improving patient care and disease prevention.”

Models using novel kidney and cardiac biomarkers were the most effective predictors of 10-year risk for atherosclerotic cardiovascular disease in chronic kidney disease patients, in a new study.

Chronic kidney disease (CKD) patients may be at increased risk for atherosclerotic cardiovascular disease, but no ASCVD risk prediction models are currently in place to inform clinical care and prevention strategies, Joshua Bundy, PhD, of Tulane University, New Orleans, and colleagues wrote in their paper, published in the Journal of the American Society of Nephrology.

Dr. Joshua Bundy

To improve the accuracy of ASCVD risk prediction, the researchers developed several models using data from the Chronic Renal Insufficiency Cohort (CRIC) study. This longitudinal cohort study included more than 2,500 adult CKD patients. The participants’ ages ranged from 21-74 years, with the mean age having been 55.8 years, and 52.0% of the cohort was male.

Kidney function was defined using the glomerular filtration rate; the mean estimated glomerular filtration rate (eGFR) of the study participants was 56.0 mL/min per 1.73m2. The primary endpoint for the prediction models was incident ASCVD, defined as a composite of incident fatal or nonfatal stroke or MI.

A total of 252 incident ASCVD events occurred during the first 10 years of follow-up from baseline (1.9 events per 1,000 person-years). Patients with ASCVD events were more likely to be older, Black, and current smokers. They also were more likely than those who did not experience ASCVD events to have less than a college level education, to have a history of diabetes, and to use blood pressure–lowering medications.

“In our study, we created two new prediction tools for patients with CKD: the first is a simple model that includes factors routinely measured by health care providers and the second is an expanded model with additional variables particularly important to patients with CKD, including measures of long-term blood sugar, inflammation, and kidney and heart injury,” he explained. “We found that the new models are better able to classify patients who will or will not have a stroke or heart attack within 10 years, compared with the standard models.

Review finds anti-staphylococcus treatments have little impact on eczema

Article Type
Changed

Current interventions to tackle Staphylococcus aureus in patients with atopic eczema have little impact on symptoms, based on data from a Cochrane Review of 41 studies published in Clinical and Experimental Allergy.

Eczema remains a huge disease burden worldwide, and colonization with S. aureus in eczema patients is common, but no standard intervention exists to relieve symptoms, wrote Nandini Banerjee, MD, of Addenbrooke’s Hospital, Cambridge, England. “While antibiotic treatment of clinically obvious infections such as cellulitis is beneficial, it is not clear whether antibiotic treatment of eczema influences eczema severity,” Dr. Banerjee noted.

The 41 studies included 1,753 participants and 10 treatment categories. Most of the studies were conducted in secondary care centers in Western Europe, North America, and the Far East. Twelve studies included children, four included only adults, 19 included children and adults, and in six studies, the participant age range was unclear. Among the studies with reported ages, the mean age ranged from 1.1 to 34.6 years. Eczema severity ranged from mild to severe, and treatment durations ranged from 10 minutes to 3 months.

The review presented comparisons of topical steroid/antibiotic combinations, oral antibiotics, and bleach baths. In 14 studies that compared topical steroid/antibiotic combinations to topical steroids alone, patients showed slightly greater global improvement in symptoms with the combination, but the impact on quality of life was not significantly different. Severe adverse events, including flare of dermatitis, worsening of eczema, and folliculitis, were reported by the patients who received the combination and the topical steroid–only patients. One study reported similar rates of antibiotic resistance in children treated with steroid only and with an antibiotic/steroid combination at 3 months’ follow-up.



In four studies, oral antibiotics “may make no difference in terms of good or excellent global improvement in infants and children at 14 to 28 days follow-up compared to placebo,” according to the review. The reviewers said that there was likely little or no difference in quality of life for infants and children given oral antibiotics, although they noted the low quality of evidence on this topic.

Five studies evaluated the impact of bleach baths on eczema patients with and without S. aureus infections. These studies showed no difference in global improvement measures compared with placebo and little or no difference in quality of life. Also, patients who underwent bleach baths compared with placebo patients reported similar adverse events of burning/stinging or dry skin at 2 months’ follow-up.

“Low-quality evidence, due to risk of bias, imprecise effect estimates, and heterogeneity, made pooling of results difficult,” Dr. Banerjee wrote. “Topical steroid/antibiotic combinations may be associated with possible small improvements in good or excellent signs/symptoms compared with topical steroid alone. High-quality trials evaluating efficacy, QOL, and antibiotic resistance are required,” she concluded.

In a commentary section after the review, Dr. Banerjee and colleagues noted that the United Kingdom’s NICE guidelines for managing atopic eczema in children younger than 12 years of age, published in March 2021, include evidence from the current updated Cochrane Review. The NICE guidelines emphasize that “in people who are not systemically unwell, clinicians should not routinely offer either a topical or oral antibiotic for secondary bacterial infection of eczema,” the Cochrane authors said. They added in their commentary that the use of antibiotics in cases of nonsevere infections can worsen eczema. Also, “the risk of antimicrobial resistance is high with topical antibiotics, and therefore extended doses of the same antibiotics should be avoided to prevent resistance,” they said. However, the authors acknowledged a role for antibiotics in certain situations. “In patients with systemic signs of infection such as cellulitis, systemic antibiotics have an important role in helping clear infection,” they noted.

 

 

Reasons for varying disease severity elude research

The current study is important because of the abundance of preclinical and clinical data that implicate S. aureus in atopic dermatitis pathogenesis, Brian Kim, MD, of the Icahn School of Medicine at Mount Sinai, New York, said in an interview.

Dr. Kim said that he was surprised by some of the study findings but not others. “On the one hand, I thought there would be data supporting antimicrobial therapy, albeit not strong support,” he said. “However, AD is a very complex disease, and understanding what a disease modifier does to it is hard to capture across studies of various different designs,” he said.

“The data supporting antimicrobial therapy for S. aureus in AD is not as clear as our clinical impressions may indicate,” said Dr. Kim. “We need to understand the relationship better, perhaps in particular subsets of patients,” he emphasized. In addition, “We need a better understanding of why some people are colonized with S. aureus, yet with little effect on AD itself, while others experience severe exacerbation of disease,” said Dr. Kim. Therefore, a key research question for future studies is whether the exacerbation is caused by the particular strain of the bug, the host susceptibility, or both, he said.

The review received no outside funding. Dr. Banerjee and Dr. Kim have disclosed that they had no relevant financial relationships.

Dupilumab under FDA review for atopic dermatitis in children aged 6 months to 5 years

Article Type
Changed

The Food and Drug Administration has accepted a supplemental Biologics License Application (sBLA) for Priority Review of dupilumab to treat moderate to severe atopic dermatitis (AD) in children aged 6 months to 5 years, according to a statement from the manufacturers, Regeneron and Sanofi.

If approved, dupilumab would be the first biologic approved for children in this age group in the United States, according to the statement. The proposed indication is as add-on therapy for children with moderate to severe AD not adequately controlled with topical prescription therapies or for whom topical therapies are not advised. The FDA granted breakthrough therapy designation for dupilumab for the treatment of severe AD in children aged 6 months to 11 years in 2016.

Approximately 85%-95% of atopic dermatitis patients develop symptoms before 5 years of age, and these symptoms often continue into adulthood, with an increased risk of skin infections and a significant impact on quality of life, according to the statement.

The sBLA is based on data from a phase 3 pivotal study of 162 children aged 6 months to 5 years in which dupilumab was added to standard-of-care topical corticosteroids, presented in December 2021. In the study, dupilumab plus standard of care significantly improved skin clearance and reduced overall disease severity and itch at 16 weeks compared with standard of care alone. Overall, 28% of the children randomized to dupilumab achieved the primary endpoint of clear or almost-clear skin, compared with 4% with those on standard of care alone (P < .0001), according to the manufacturers. Patients in the dupilumab group received either 200 mg (for children weighing ≥ 5 to < 15 kg) or 300 mg (for children weighing ≥ 15 to < 30 kg) every 4 weeks. Safety results were similar to those seen with dupilumab for children aged 6 years and older.

Conjunctivitis and herpes infections were among the most common adverse events associated with dupilumab in the study, according to the statement.

The target action date for the FDA decision on this application is June 9, 2022.

E-cigarettes don’t help smokers quit, suggests new research

Article Type
Changed

Use of e-cigarettes was not more effective than other methods at helping cigarette smokers quit, authors of new research found.

From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.

In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.

“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.

Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.

*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.

The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.

More research needed

The researchers acknowledged the need to review more recent data.

“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.

Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.

The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
 

 

 

Several findings surprised study author

Dr. Pierce said he was surprised by several aspects of the study findings.

“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.

“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.

The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.

“We don’t know about the high-nicotine versions,” he added. 
 

New review advises against e-cigarettes for cessation

A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.

“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.

The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.

Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.

With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.

In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.

The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.

Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”

“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
 

 

 

Findings may guide patient conversations

The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.

“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.

Dr. Girgis also said she was not surprised by the findings.

“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.

“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.

With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.

Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.

“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”

“To continue to use e-cigarettes indefinitely should not be the goal,” she added.

The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.

The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group. Lead author Dr. Rigotti disclosed funding from the National Heart, Lung, and Blood Institute and Achieve Life Sciences and personal fees from UpToDate and Achieve Life Sciences. Dr. Girgis had no financial conflicts to disclose.
