Policies increasing access to immediate postpartum long-acting reversible contraception (LARC) were associated with reductions in preterm birth and low birth weight, based on data from South Carolina’s Medicaid program.

Preterm birth and low birth weight represent the second-leading cause of infant mortality in the United States, wrote Maria W. Steenland, SD, of Brown University, Providence, R.I., and colleagues. Previous policy interventions to reduce preterm birth and low birth weight have focused on services before and during pregnancy, they said. LARC is a safe and effective postpartum intervention, but cost has been a limiting factor, they noted.

In 2012, the Medicaid program in South Carolina began reimbursing hospitals for immediate postpartum LARC independent of global maternity payments. In a previous study, the researchers found that the implementation of this policy had reduced the number of short-interval births among adolescents.

The goal of the current study, published in JAMA Pediatrics, was to analyze the association between South Carolina’s policy change and rates of preterm birth and low birth weight among individuals with Medicaid coverage during childbirth. The researchers analyzed data from 186,953 Medicaid-paid births between January 2009 and December 2015 in South Carolina. Of these, 46,414 births (24.8%) occurred in hospitals that provided immediate postpartum LARC in response to the policy change. Overall, the implementing hospitals had more annual births paid for by Medicaid compared to nonimplementing hospitals (1,105 vs. 511) and were less likely to be rural (33.3% vs. 46.8%) and had a greater share of preterm births (15.5% vs. 9.5%). Prior to the policy change, the probability of a preterm birth in the next 4 years was 4.4% for patients at implementing hospitals and 3.5% for those in nonimplementing hospitals, and the probability of a low-birth-weight birth was 3.6% and 2.9%, respectively.

The policy change was associated with a decrease of 0.4 percentage points for preterm birth and 0.3 percentage points for subsequent low-birth-weight birth.

When the results were stratified based on race and ethnicity, the policy change was associated with a decrease of 0.5 percentage points in the probability of preterm birth in both non-Hispanic Blacks and non-Hispanic Whites. No significant differences appeared in the association between the policy change and rates of preterm birth or low-birth-weight birth between non-Hispanic Black and non-Hispanic White individuals.

However, the policy was associated with a significant decrease of 0.6 percentage points in the probability of short-interval birth among non-Hispanic Blacks, and a decrease of 1.6 percentage points in the probability of another birth within 4 years overall. The policy change also was associated with a significant increase of 27 days between births among non-Hispanic Blacks, but not with any significant change among non-Hispanic Whites or the study population overall.

“In addition, although our data cannot speak to this, the policy may have affected the intendedness of subsequent pregnancies, leading to healthier behaviors before and during pregnancy, such as early initiation of prenatal care,” the researchers wrote in their discussion of the findings.

The study findings were limited by several factors including the lack of data on pregnancy intention or abortion, and the lack of data on patient-reported outcomes, notably the provision of patient-centered counseling and whether such counseling was biased, the researchers noted. Other limitations included a lack of data on infant mortality and potential confounding from risk profiles of patients in implementing vs. nonimplementing hospitals, they wrote.

Also, the study provides population-level data, which does not guide clinical decision-making about intervals between childbirth and subsequent pregnancy, the researchers emphasized.

Although the data support the value of postpartum contraception in improving birth outcomes, “it is imperative that efforts to expand access focus on assuring comprehensive access to all forms of contraception without coercion,” the researchers concluded. “Additional policy solutions are needed to improve infant health, including those that directly address structural and interpersonal racism to reduce racial disparities in infant health,” they said.

The study is important because, although immediate postpartum LARC policies were first implemented almost a decade ago in the United States, population-level evidence on the effects of these policies remains scarce, Dr. Steenland said in an interview.  

Existing barriers to improving access to immediate postpartum LARC include health professional training and logistics within hospitals, as well as ensuring correct billing and timely reimbursements, Dr. Steenland said. “Simple and clear billing procedures, and advanced reimbursement so that hospitals can have devices stocked would make it easier to provide this service,” she noted.

“This service has gone from being almost completely unavailable, to available in some hospitals, mainly those that are urban, teaching, and high volume,” said Dr. Steenland. “Additional research is needed to determine how health systems can make this service available to all birthing persons,” she said. “Also, critically, additional research is needed to identify strategies to ensure that counseling for immediate postpartum LARC, and family planning more generally, is patient-centered, so that the availability of immediate postpartum LARC increases, rather than restricts, choice,” she added. “Finally, additional research is needed to determine whether postpartum people have affordable and accessible access to LARC removal services,” Dr. Steenland emphasized.
 

Immediate post partum is critical period

The immediate postpartum period is a critical time for access to contraception because many women do not return for postpartum visits after hospital discharge, Tracey A. Wilkinson, MD, and Jeffrey F. Peipert, MD, of Indiana University, Indianapolis, wrote in an accompanying editorial. “The focus on contraception access during the postpartum period prior to hospital discharge is important because of the potential sequelae of a subsequent unintended pregnancy or short interpregnancy intervals,” they noted. These issues may be more acute in marginalized communities, and policies to expand immediate postpartum LARC are in place in a majority of states, the editorialists said.

However, they agreed with the authors’ statements that implementation of LARC must be done in a manner that supports patient choice and avoids coercion. Given the baseline disparities of the infant outcomes studied, increased access to immediate postpartum LARC must be provided in a way that does not exacerbate these disparities, they said. “This ultimately means that plans to increase access to contraception should emphasize availability while avoiding coercion, and if a patient ultimately decides to discontinue a method, enable that to occur easily and seamlessly, including LARC device removal,” they explained.

“Future studies examining patient centeredness of these postpartum LARC implementation efforts would be an important element to augment these data and show the impact in additional spheres beyond infant outcomes,” they added.
 

Overcome trust barriers and offer options

“In a time of restrictive access to abortion and contraception in many states, any additional increase in access can potentially be meaningful,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. “Additionally, given the significantly higher rates of infant and maternal morbidity and mortality among the non-Hispanic Black population, seeing an intervention that can improve outcomes for both mothers and babies is also potentially very positive,” she said.

Dr. Prager said she was not surprised by the study findings, as immediate LARC is much more common in other countries and has shown similar outcomes. “Additionally, I am reassured by the fact that the increased number of days until the next pregnancy is not higher, as this indirectly indicates that patients were able to get their LARC removed when they desired another pregnancy,” she noted.

Barriers to improving access to immediate postpartum LARC in the Medicaid population may include mistrust for any long-acting contraception, “especially if they perceive that cessation of the method will be difficult to achieve,” Dr. Prager noted. “Certainly, counseling about LARC removal should be an element of counseling prior to any initiation, and lack of access to removal of an IUD or implant can be categorized as a form of reproductive coercion,” she said. Dr. Prager said that such counseling might be more effective if it occurred during prenatal visits, “so if providers are not talking about this during routine OB visits and patients only hear about immediate postpartum LARC when they are in the hospital for delivery, they may be less likely to accept the practice,” she said. “Finally, although Medicaid will cover the cost of immediate postpartum LARC, private insurers do not do so consistently in all states, so some hospitals may find this process too difficult to navigate and therefore not offer immediate postpartum LARC,” Dr. Prager emphasized.

As for additional research, Dr. Prager said she would like to see more studies in an overall United States population of pregnant people, both Medicaid patients and others, on whether the immediate postpartum timing of LARC is desired.

“I would like to couple that with patients’ impressions or experiences of their ability to access contraception outside of the immediate postpartum time period, and also their impressions or experience with ability to have LARC removed, since they are the only contraceptives not necessarily within personal control for initiation or cessation,” Dr. Prager said.

The researchers had no financial conflicts to disclose. The editorial was supported in part by the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Field cancerization and subsequent second cancer in squamous cell carcinoma (SCC) patients was significantly associated with cigarette and alcohol use, based on data from more than 300 individuals.

Cigarette and alcohol use are established risk factors for SCCs of the esophagus, head, and neck, Manabu Moto, MD, of Kyoto University and colleagues wrote. “In addition, squamous cell carcinoma and squamous dysplastic epithelium develop multifocally in these organs,” in a phenomenon known as field cancerization, but the interaction of multiple dysplastic epithelium with other factors, notably whether cessation of cigarette and alcohol use would reduce risk of SCC, has not been well studied.

In a study published in Gastro Hep Advances, the researchers identified 331 adults with newly diagnosed superficial esophageal SCC who underwent endoscopic resection, and 1,022 healthy controls. Field cancerization was based on the number of Lugol-voiding lesions (LVLs) per endoscopic view according to three groups: grade A, 0 LVLs; grade B, 1-9; or grade C, at least 10. The primary study outcome was a measure of risk factors for the development of LVLs.

“Multiple LVLs are closely associated with inactive aldehyde dehydrogenase 2 (ALDH2) and field cancerization,” the researchers wrote. Before assessing their human subjects, they used a mouse model to investigate whether alcohol intake and abstinence would affect acetaldehyde-induced DNA damage to the esophageal epithelium among individuals with ALDH2 dysfunction.

The researchers found that DNA damage, measured by acetaldehyde-derived DNA adduct levels (via N²-ethylidene-dG), accumulated with alcohol consumption over time, but decreased with alcohol cessation in the mouse model.

For the human part of the study, participants completed a lifestyle survey at entry, with questions about alcohol consumption history, alcohol flushing response, smoking, consumption of high-temperature foods, and consumption of green and yellow vegetables and fruit. Drinking status was divided into five groups: never/rarely (of less than 1 unit/week), light (1-8.9 units/week), moderate (9-17.9 units/week), heavy (18 or more units/week), and ex-drinker, with 1 unit defined as 22 g of ethanol. Smoking was divided into three groups: never (0 pack-years), light (less than 30 pack-years), and heavy (30 or more pack-years). Patients were given educational materials at study entry about the importance of alcohol and smoking cessation, as well as verbal advice to cease these behaviors.

Participants underwent endoscopic surveillance at 3-month intervals for up to 6 months following endoscopic resection.

Overall, increased alcohol consumption was associated with increased risk in development of LVL across all LVL grades; higher grades of LVLs were positively associated with high-intensity alcohol consumption, smoking, flushing, and high-temperature foods, and negatively associated with eating vegetables and fruit.

The risk of LVL grade progression was most strongly associated with increased alcohol consumption and with reported flushing. “The greatest risk was observed in the patients with flushing reactions who consumed an average of 30 units per week in grade C LVL,” with an odds ratio of 534, compared with healthy controls. “Since flushing reaction is caused by accumulation of acetaldehyde due to ALDH2 deficient, our result also means that acetaldehyde is a strong carcinogen in field cancerization.”

Secondary outcomes included the incidence of second primary esophageal SCC and head/neck SCC; these were significantly more prevalent in patients with grade C LVL (cumulative 5-year incidence of 47.1% for ESCC and 13.3% for head and neck SCC). However, alcohol and smoking cessation significantly reduced the development of second primary esophageal SCC (adjusted hazard ratios, 0.47 for alcohol and 0.49 for smoking).

The study findings were limited by several factors including the lack of randomization to noncessation and cessation groups and the inclusion of cancer patients, but not long-term cancer survivors, the researchers noted.

“We believe that our data will be useful to establish a prevention and surveillance strategy for cancer survivors, because the overall prognosis of esophageal cancer and head and neck cancer is still poor,” with a 5-year survival rate of less than 20%, and the results highlight the need to educate cancer survivors on the value of smoking and alcohol cessation, they added.

The study was supported by the National Cancer Center Research and Development Fund 36 by the Ministry of Health, Labour, and Welfare of Japan. The researchers had no financial conflicts to disclose.

“We believe that our data will be useful to establish a prevention and surveillance strategy for cancer survivors, because the overall prognosis of esophageal cancer and head and neck cancer is still poor,” with a 5-year survival rate of less than 20%, and the results highlight the need to educate cancer survivors on the value of smoking and alcohol cessation, they added.

The study was supported by the National Cancer Center Research and Development Fund 36 by the Ministry of Health, Labour, and Welfare of Japan. The researchers had no financial conflicts to disclose.

Field cancerization and subsequent second cancer in squamous cell carcinoma (SCC) patients was significantly associated with cigarette and alcohol use, based on data from more than 300 individuals.

Cigarette and alcohol use are established risk factors for SCCs of the esophagus, head, and neck, Manabu Moto, MD, of Kyoto University and colleagues wrote. “In addition, squamous cell carcinoma and squamous dysplastic epithelium develop multifocally in these organs,” in a phenomenon known as field cancerization, but the interaction of multiple dysplastic epithelium with other factors, notably whether cessation of cigarette and alcohol use would reduce risk of SCC, has not been well studied.

In a study published in Gastro Hep Advances, the researchers identified 331 adults with newly diagnosed superficial esophageal SCC who underwent endoscopic resection, and 1,022 healthy controls. Field cancerization was based on the number of Lugol-voiding lesions (LVLs) per endoscopic view according to three groups: grade A, 0 LVLs; grade B, 1-9; or grade C, at least 10. The primary study outcome was a measure of risk factors for the development of LVLs.

“Multiple LVLs are closely associated with inactive aldehyde dehydrogenase 2 (ALDH2) and field cancerization,” the researchers wrote. Before assessing their human subjects, they used a mouse model to investigate whether alcohol intake and abstinence would affect acetaldehyde-induced DNA damage to the esophageal epithelium among individuals with ALDH2 dysfunction.

The researchers found that DNA damage, measured by acetaldehyde-derived DNA adduct levels (via N²-ethylidene-dG), accumulated with alcohol consumption over time, but decreased with alcohol cessation in the mouse model.

For the human part of the study, participants completed a lifestyle survey at entry, with questions about alcohol consumption history, alcohol flushing response, smoking, consumption of high-temperature foods, and consumption of green and yellow vegetables and fruit. Drinking status was divided into five groups: never/rarely (of less than 1 unit/week), light (1-8.9 units/week), moderate (9-17.9 units/week), heavy (18 or more units/week), and ex-drinker, with 1 unit defined as 22 g of ethanol. Smoking was divided into three groups: never (0 pack-years), light (less than 30 pack-years), and heavy (30 or more pack-years). Patients were given educational materials at study entry about the importance of alcohol and smoking cessation, as well as verbal advice to cease these behaviors.

Participants underwent endoscopic surveillance at 3-month intervals for up to 6 months following endoscopic resection.

Overall, increased alcohol consumption was associated with increased risk in development of LVL across all LVL grades; higher grades of LVLs were positively associated with high-intensity alcohol consumption, smoking, flushing, and high-temperature foods, and negatively associated with eating vegetables and fruit.

The risk of LVL grade progression was most strongly associated with increased alcohol consumption and with reported flushing. “The greatest risk was observed in the patients with flushing reactions who consumed an average of 30 units per week in grade C LVL,” with an odds ratio of 534, compared with healthy controls. “Since flushing reaction is caused by accumulation of acetaldehyde due to ALDH2 deficient, our result also means that acetaldehyde is a strong carcinogen in field cancerization.”

Secondary outcomes included the incidence of second primary esophageal SCC and head/neck SCC; these were significantly more prevalent in patients with grade C LVL (cumulative 5-year incidence of 47.1% for ESCC and 13.3% for head and neck SCC). However, alcohol and smoking cessation significantly reduced the development of second primary esophageal SCC (adjusted hazard ratios, 0.47 for alcohol and 0.49 for smoking).

The study findings were limited by several factors including the lack of randomization to noncessation and cessation groups and the inclusion of cancer patients, but not long-term cancer survivors, the researchers noted.

Older adults who avoided hospital admission with at-home geriatric assessment and home-based care incurred significantly lower costs compared with those hospitalized, in a new study.

The comprehensive geriatric assessment (CGA) is an established strategy for guiding care of older adults in a hospital setting, but its use in other settings has not been well studied, Surya Singh, PhD, of the University of Oxford (England), and colleagues wrote in their paper published in Age and Ageing. Hospital at home is active treatment by health care professionals in the patient’s home for a condition that otherwise would require acute hospital inpatient care, for a limited time period.

Interest in providing health care in the home as an alternative to hospitalization is on the rise as a way to improve patient outcomes and reduce costs, but actual cost-effectiveness data on HAH interventions are limited, the authors said. “Wide scale implementation of such services has also been constrained by the practical difficulties of designing and delivering services that cut across primary and secondary care, might involve social care and require different workforce and funding arrangements.”

In this study, the researchers conducted a cost-effectiveness analysis alongside a randomized trial of an admission avoidance CGA hospital at home (CGAHAH) service as an alternative to hospital admission. They identified individuals aged 65 years and older who were living in the community but being considered for an unplanned hospital admission in the United Kingdom. A total of 700 individuals were randomized to CGAHAH and 355 to hospital care using a 2:1 ratio. Patients were assessed at baseline in the community or in an acute care setting before being transferred to CGAHAH service. These services included access to social workers, home care, district nursing, community rehabilitation, community mental health services and acute hospital services, such as diagnostic tests and transfer to hospital. The core workforce usually included consultant geriatricians, junior doctors, nurse practitioners, health care assistants or support workers, physiotherapists, occupational therapists, and community pharmacists. There were at least daily virtual ward rounds
 

Comparison between HAH and in-hospital groups

Patients in the CGAHAH group had a mean of 7.17 days of care, and those in hospital had a mean of 4.92 hospital days. At 6 months’ follow-up, the mean number of care days was 9.47 in the CGAHAH group and 10.58 in the hospital group, which was a nonsignificant difference.

“For complete cases, we found that allocation to CGAHAH resulted in 3 fewer days in hospital, a difference that was reduced to 1 day at 6 months follow-up,” the researchers wrote.

Overall, after adjusting for baseline variables, the health and social care costs after 6 months were less for CGAHAH than admission to hospital. The average cost differences between the two were approximately $3,000 or 2,265 pounds. The cost difference remained and increased to a mean difference of 2,840 pounds in favor of HAH after adding informal care/societal costs.

In addition, patients randomized to CGAHAH were less likely to have been admitted to long-term residential care at 6 months follow-up, compared with the hospital group; the mean days in residential care at 6 months were 3.43 and 6.14, respectively.

Both groups showed an approximate 15% decrease in measures of quality of life from baseline to 6 months, and no differences were noted in quality-adjusted survival between the groups.
 

Pandemic ‘has accelerated interest’ in HAH

“Health systems around the world are exploring alternatives to hospital admission, such as hospital at home, to act as a buffer to the increasing demand for hospital care,” corresponding author Sasha Shepperd, MSc, DPhil, said in an interview. “This is partly due to a growing older population with increased health needs, but also an emphasis on providing health care that limits a decline in capacity for the older population. Inevitably, the COVID-19 pandemic has accelerated interest in hospital at home to create additional acute health care capacity.”

The take home-message supports the home service option. “If you can access a hospital-at-home service, consider this as an option for older people who would otherwise be admitted to hospital and are eligible for hospital at home care. However, is important that the provision of hospital at home is adequately resourced, and that families and caregivers are supported,” she said.

“Barriers include delivering a different type of service that requires easy access to hospital services, including admission if required; a trained workforce to provide multidisciplinary care in a patient’s home; and ensuring a good fit with existing health and social care services,” Dr. Shepperd said.

Future research areas include the demands placed on caregivers from hospital-at-home services, and how the provision of hospital at home impacts hospital and community services, she added.

Findings support use of HAH

The data from the current study support the use of a hospital at home concept, especially in the geriatric age population, for acute health conditions that could be managed at home rather than acutely in a hospital-based environment,” Noel Deep, MD, emphasized in an interview.

Dr. Deep, who is a general internist in group practice in Antigo, Wisc., said he was not surprised by the study findings.

“I am a big proponent of the hospital at home approach to taking care of patients who can be safely and appropriately managed in the familiarity and comfort of their own home environment with help from physicians, nurses, and other home health care services,” he said. “It is a valuable option for appropriately screened and selected patients to be provided this approach to management of their acute health care situations.”

Primary care physicians should explore using HAH when faced with the decision of admitting an elderly individual to the hospital for management of an acute worsening of a chronic medical condition or a reversible acute illness, said Dr. Deep, who serves on the editorial advisory board of Internal Medicine News.

The current study reinforces previous studies and data showing the benefits of managing acute health problems of elderly individuals in their home environment. These benefits include “an opportunity to free up the emergency rooms and hospitals for providing care to those individuals who truly would be best served by being admitted to the hospital,” Dr. Deep explained. Home care for the elderly “would also lead to decreased utilization of the personal protective equipment and limit exposure of the vulnerable elderly individuals to the coronavirus. Primary care physicians should always explore this possibility of providing care to the patients in their homes if it is a viable option.

“While our practice environment [in the United States] is slightly different than that referenced in this article, many, if not almost all, of our primary care physicians provide care to the geriatric age population and provide assessment and management which would be comparable to this comprehensive geriatric assessment that is discussed in the article,” and many primary care physicians have seen similar results in outcomes that the study shows, said Dr. Deep. The available research and expert opinions are quite similar and agree upon the positive outcomes in terms of providing the CGAHAH approach.
 

Study is important but raises questions

The study is important because patient-centered, effective care should be the goal of any health system, William Golden, MD, of the University of Arkansas for Medical Sciences, Little Rock, said in an interview. 

Dr. Golden also noted that the study raised a number of questions. How each patient entered the treatment protocol was not clear. “Similarly, it is not clear whether admission criteria and resource costs in England cross to the United States experience.”

“Having close follow up of patients at home as opposed to an ‘observation status’ could be a nice innovation, but more details are needed to consider implementation in a specific community setting,” he emphasized.

As for the clinical value of the study for primary care, “primary care professionals should welcome well-staffed alternatives to inpatient care for select patient presentations,” said Dr. Golden, who is also a member of the editorial advisory board of Internal Medicine News.

The current study does not identify the conditions that were treated at home and the logistics of delivering such services, which limits comparison with what experts have seen in practice in terms of outcomes using the CGAHAH, he said. “Interested practitioners would benefit from literature detailing the staffing and decision support tools that form the core framework of this innovation.”
 

Limitations and strengths of study, according to authors

The study findings were limited by several factors including the calculation of CGAHAH based on service budgets, rather than from collecting information on the actual resources used; potential errors in patients’ estimation of their informal care; and lack of data on a differential impact of CGAHAH for underserved communities, the researchers noted.

However, the results were strengthened by the large study population and randomized design, and support the value of CGAHAH, which addresses the need for management of multiple long-term conditions and the potential decline in functional and cognitive ability in older adults, they said. Providing CGAHAH as an alternative to admission to hospital for older people, with a focus on multidimensional assessment, is one option that might reduce reliance on hospitalization and residential care and at a lower cost.

The study was supported by the National Institute for Health Research, and several coauthors received individual grants from the NIHR, with no other financial conflicts to disclose. Dr. Golden and Dr. Deep had no financial conflicts to disclose.

Preschoolers who experienced community-acquired pneumonia in infancy were significantly more likely than were those with no history of pneumonia to develop chronic respiratory disorders, based on data from approximately 7,000 individuals.

“Lower respiratory tract infections (LRTI) during the first years of life cause injury to the rapidly developing lung at its most critical stage,” wrote Rotem Lapidot, MD, of Boston University, and colleagues. Previous research has linked pneumonia with subsequent chronic cough, bronchitis, and recurrent pneumonia in children, but data are needed to assess the impact of early community-acquired pneumonia (CAP) on respiratory health in otherwise healthy infants, the researchers said.

In a retrospective matched cohort study published in Respiratory Medicine , the researchers identified 1,343 infants who had CAP in the first 2 years of life, and 6,715 controls, using a large electronic health records dataset (Optum EHR dataset) for the period from Jan. 2011 through June 2018.

The primary outcomes were the development of any chronic respiratory disorders, reactive airway disease, and CAP hospitalizations between ages 2 and 5 years. Infants in the CAP group were otherwise healthy; those with congenital or other conditions that might predispose them to pneumonia were excluded. Baseline characteristics were similar between the CAP patients and controls.
 

Future risk

Overall, the rates per 100 patient-years for any chronic respiratory disorder were 11.6 for CAP patients versus 4.9 for controls (relative risk, 2.4). Rates for reactive airway disease and CAP hospitalization were 6.1 versus 1.9 per 100 patient-years (RR, 3.2) and 1.0 versus 0.2 per 100 patient-years (RR, 6.3) for the CAP patients and controls, respectively.

The distribution of CAP etiology of CAP in infants at the first hospitalization was 20% bacterial, 27% viral, and 53% unspecified. The relative rates of later respiratory illness were similar across etiologies of the initial hospitalization for CAP, which support the association between infant CAP and later respiratory disease, the researchers said.

Nearly all (97%) of the CAP patients had only one qualifying hospitalization for CAP before 2 years of age, and the mean age at the first hospitalization was 8.9 months. “Rates and relative rates of any chronic respiratory disorder, and our composite for reactive airway disease, increased with age at which the initial CAP hospitalization occurred,” and were highest for children hospitalized at close to 2 years of age, the researchers noted.
 

Persistent inflammation?

“Our findings add to the evolving hypothesis that persistent inflammation following pneumonia creates an increased risk for subsequent respiratory disease and exacerbations of underlying disease,” the researchers wrote.

The study findings were limited by several factors, including the potential for misclassification of some infants with and without underlying conditions, reliance on discharge information for etiology, and possible lack of generalizability to other populations, the researchers noted.

However, the results indicate an increased risk for respiratory illness in early childhood among infants with CAP, and support the need for greater attention to CAP prevention and for strategies to reduce inflammation after pneumonia, they said. “Further study is needed to confirm the long-term consequences of infant CAP and the underlying mechanisms that lead to such long-term sequelae,” they concluded.

Dr. Lapidot and several coauthors disclosed ties with Pfizer, the study sponsor.

In a retrospective matched cohort study published in Respiratory Medicine , the researchers identified 1,343 infants who had CAP in the first 2 years of life, and 6,715 controls, using a large electronic health records dataset (Optum EHR dataset) for the period from Jan. 2011 through June 2018.

The primary outcomes were the development of any chronic respiratory disorders, reactive airway disease, and CAP hospitalizations between ages 2 and 5 years. Infants in the CAP group were otherwise healthy; those with congenital or other conditions that might predispose them to pneumonia were excluded. Baseline characteristics were similar between the CAP patients and controls.
 

Future risk

Overall, the rates per 100 patient-years for any chronic respiratory disorder were 11.6 for CAP patients versus 4.9 for controls (relative risk, 2.4). Rates for reactive airway disease and CAP hospitalization were 6.1 versus 1.9 per 100 patient-years (RR, 3.2) and 1.0 versus 0.2 per 100 patient-years (RR, 6.3) for the CAP patients and controls, respectively.

The distribution of CAP etiology of CAP in infants at the first hospitalization was 20% bacterial, 27% viral, and 53% unspecified. The relative rates of later respiratory illness were similar across etiologies of the initial hospitalization for CAP, which support the association between infant CAP and later respiratory disease, the researchers said.

Nearly all (97%) of the CAP patients had only one qualifying hospitalization for CAP before 2 years of age, and the mean age at the first hospitalization was 8.9 months. “Rates and relative rates of any chronic respiratory disorder, and our composite for reactive airway disease, increased with age at which the initial CAP hospitalization occurred,” and were highest for children hospitalized at close to 2 years of age, the researchers noted.
 

Persistent inflammation?

“Our findings add to the evolving hypothesis that persistent inflammation following pneumonia creates an increased risk for subsequent respiratory disease and exacerbations of underlying disease,” the researchers wrote.

The study findings were limited by several factors, including the potential for misclassification of some infants with and without underlying conditions, reliance on discharge information for etiology, and possible lack of generalizability to other populations, the researchers noted.

However, the results indicate an increased risk for respiratory illness in early childhood among infants with CAP, and support the need for greater attention to CAP prevention and for strategies to reduce inflammation after pneumonia, they said. “Further study is needed to confirm the long-term consequences of infant CAP and the underlying mechanisms that lead to such long-term sequelae,” they concluded.

Preschoolers who experienced community-acquired pneumonia in infancy were significantly more likely than were those with no history of pneumonia to develop chronic respiratory disorders, based on data from approximately 7,000 individuals.

A steroid-free clinical response had no impact on multiple components of Crohn’s disease progression, based on data from 95 adults.

The therapeutic goals of Crohn’s disease have evolved from controlling symptoms to blocking disease progression and reducing complications, wrote David Laharie, MD, of Hôpital Haut-Lévêque, Pessac, France, and colleagues. The goal of steroid-free remission has been used as an endpoint of treatment, but data on the impact of such remission on long-term disease are limited, the researchers noted in a retrospective study published in Clinical Gastroenterology and Hepatology.

In the study, the researchers reviewed data from 95 adults with early Crohn’s disease (CD) who participated in the TAILORIX trial involving treatment with infliximab and immunosuppressants. The primary endpoint of the TAILORIX trial was sustained corticosteroid-free remission from week 22 to 54. In the current study, the primary endpoint was progression-free survival at 1, 3, and 5 years in patients who did or did not meet the TAILORIX primary endpoint. The median disease duration was 4.5 months, and the median follow-up was 64.2 months.

Progression-free survival was defined as a composite of luminal surgery, anal surgery, hospitalization, and the need for a new CD treatment during the follow-up period.

In the study population, 45 patients achieved corticosteroid-free remission and 50 did not. At 54 weeks, 17 patients with corticosteroid-free remission (38%) and 28 patients without remission (56%) achieved complete mucosal healing, and progression-free survival rates were similar between these groups.

Overall, the rates of progression-free survival at 1, 3, and 5 years were not significantly different between the remission and nonremission groups: 86% versus 91%, respectively, at 1 year; 70% for both groups at 3 years; and 64% and 61%, respectively, at 5 years.

The researchers also compared individual components of the primary endpoint (luminal surgery, anal surgery, hospitalization, and the need for a new CD treatment), and found no significant differences in survival rates in patients who had and had not achieved steroid-free remission.

Survival rates without luminal surgery at 1, 3, and 5 years were 97% versus 96%, 93% versus 90%, and 87% versus 82%, respectively, for remission and nonremission groups. Similarly, survival rates without anal surgery were 93%, 86%, and 86% versus 96%, 88%, and 85%, respectively, for the two groups. Rates of hospitalization-free survival at 1, 3, and 5 years were 90% versus 92%, 81% versus 81%, and 78% versus 69%, respectively, in the remission and nonremission groups. Survival rates without a new systemic CD treatment also were similar at 1, 3, and 5 years: 93% versus 95%, 71% versus 93%, and 60% versus 51%, respectively, for the remission and nonremission groups.

CD progression was not associated with not achieving corticosteroid-free remission (hazard ratio, 0.861). Other factors that were not associated with disease progression in this study included CRP greater than 5 mg/L, age older than 30 years, active smoking, and B1 phenotype.

The researchers noted that, although endoscopic and clinical remission is currently recommended for CD, “there is no validated or standardized definition of this endoscopic goal.” The high rates of survival without major abdominal surgery, regardless of remission status, suggest a significant impact of early combination therapy for CD patients who were biologic naive. Other studies have shown similar improved outcomes for CD patients with early treatment.

The study findings were limited by several factors including the retrospective design and lack of power to compare long-term progression-free survival, the researchers noted. However, the results were strengthened by the robust data on hospitalizations and surgeries from the TAILORIX trial.

The results support a more flexible strategy for CD, “recommending endoscopic and clinical remission in early diagnosed patients and less stringent objectives in those with more refractory or advanced disease,” they concluded.
 

Findings may guide patient management

The current study is important to help clinicians know whether CD patients who achieve a short-term, steroid-free clinical and endoscopic remission go on to experience better long-term disease outcomes than those who do not achieve this short-term remission, Atsushi Sakuraba, MD, of the University of Chicago said in an interview.

Dr. Sakuraba said that he was surprised by the study findings. “Achieving a clinical remission off steroids with complete endoscopic remission, i.e., deep remission, is considered a treatment goal, but the fact that it did not result in less disease progression was surprising.”

The take-home message for clinicians from the study is that CD patients may still experience disease progression after achieving a single time of clinical and endoscopic remission “mainly due to loss of response to infliximab, so continued long-term disease monitoring and control are required,” Dr. Sakuraba said.

The current study was a post hoc follow-up analysis of a previous trial, Dr. Sakuraba noted. Therefore, studies primarily focused on changing the disease progression and natural course of CD are warranted.

Mutations in genes associated with cardiac and seizure disorders appear to be linked to sudden unexplained deaths in young children and may explain nearly 9% of such cases, researchers have found.

Previous studies have found de novo genetic variants – those not found in either parent but which occur for the first time in their offspring – that increase the risk of cardiac and seizure disorders, but research on sudden unexplained deaths in children (SUDC) is limited, according to Matthew Halvorsen, PhD, of the University of North Carolina at Chapel Hill, and colleagues. Most cases of SUDC occur in children aged 1-4 years, and a lack of standardized investigation systems likely leads to misclassification of these deaths, they said.

Compared with sudden infant death syndrome (SIDS), which occurs in approximately 1,400 children in the United States each year, approximately 400 children aged 1 year and older die from SUDC annually. A major obstacle to studying these cases is that so-called molecular autopsies – which incorporate genetic analysis into the postmortem examination – typically do not assess the parents’ genetic information and thus limit the ability to identify de novo mutations, they added.

In a study published in the Proceedings of the National Academy of Sciences, Dr. Halvorsen’s group obtained whole exome sequence data from 124 “trios,” meaning a dead child and two living parents. They tested for excessive de novo mutations for different genes involved in conditions that included cardiac arrhythmias and epilepsy. The average age at the time of death for the children was 34.2 months; 54% were male, and 82% were White.

Children who died of SUDC were nearly 10 times as likely to have de novo mutations in genes associated with cardiac and seizure disorders as were unrelated healthy controls (odds ratio, 9.76). Most pathogenic variants were de novo, which highlights the importance of trio studies, the researchers noted.

The researchers identified 11 variants associated with increased risk of SUDC, 7 of which were de novo. Three of the 124 cases carried mutations (two for RYR2 and 1 for TNNI3) affecting genes in the CardiacEpilepsy dataset proposed by the American College of Medical Genetics and Genomics, strengthening the connection to seizure disorders.

Another notable finding was the identification of six de novo mutations involved in altering calcium-related regulation, which suggests a cardiac susceptibility to sudden death.

The data support “novel genetic causes of pediatric sudden deaths that could be discovered with larger cohorts,” the researchers noted. Taken together, they say, the gene mutations could play a role in approximately 9% of SUDC cases.

The study findings were limited by several factors, including lack of population-based case ascertainment, exclusive focus on unexplained deaths, potentially missed mutations, and use of DNA from blood as opposed to organs, the researchers noted.

However, they concluded, “the data indicate that deleterious de novo mutations are significant genetic risk factors for childhood sudden unexplained death, and that their identification may lead to medical intervention that ultimately saves lives.”

Findings highlight impact of SUDC

“This study is important because SUDC is a much more pressing medical need than most people realize,” said Richard Tsien, PhD, of New York University Langone Medical Center, and the corresponding author of the study.

Although SUDC is less common than SIDS, SUDC has essentially no targeted research funding, Dr. Tsien said. Study coauthor Laura Gould, MA, a researcher and mother who lost a young child to SUDC, worked with Orrin Devinsky, MD, to create a registry for families with cases of SUDC. This registry was instrumental in allowing the researchers to “do the molecular detective work we need to do” to see whether a genetic basis exists for SUDC, Dr. Tsien said.

“The detective work comes up with a consistent story,” he said. “More than half of the genes that we found are involved in the normal function of the heart and brain,” performing such functions as delivering calcium ions to the inside of the heart cells and nerve cells.

The study “is the first of its kind,” given the difficulty of acquiring DNA from the child and two parents in SUDC cases, Dr. Tsien said.

Overall, approximately 10% of the cases have a compelling explanation based on the coding of DNA, Dr. Tsien said. From a clinical standpoint, that information might affect what a clinician says to a parent.

A key takeaway is that most of the genetic mutations are spontaneous and are not inherited from the parents, Dr. Tsien said. The study findings indicate that parents who suffer an SUDC loss need not be discouraged from having children, he added.

For the long term, “the more we understand about these disorders, the more information we can offer to families,” he said. Eventually, clinicians might be able to use genetics to identify signs of when SUDC might be more likely. “For example, if a child shows a very mild seizure, this would alert them that there might be potential for a more drastic outcome.”

Meanwhile, families with SUDC cases may find support and benefit in signing up for the registry and knowing that other families have been through a similar experience, Dr. Tsien said.

Genetic studies create opportunities

A significant portion of pediatric mortality remains unexplained, according to Richard D. Goldstein, MD, of Boston Children’s Hospital. One reason is the lack of a formal diagnostic code to identify these deaths.

Research to date has suggested links between SUDC and a family history of febrile seizures, as well as differences in brain structure associated with epilepsy, Dr. Goldstein said.

“An important hypothesis is that these deaths are part of a continuum that also includes stillbirths, SIDS, and sudden unexpected death in epilepsy [SUDEP],” Dr. Goldstein said. “By mandate, investigations of these deaths occur under the jurisdiction of medical examiners and coroners and have, for the most part, been insulated from developments in modern medicine like genomics and proteomics, elements of what are referred to as the molecular autopsy, and studies such as the current study bring attention to what is being missed.”

Dr. Goldstein said the new study buttresses the “conventional clinical suspicion” about the likely causes of SUDC, “but also strengthens the association between sudden unexpected death in pediatrics (SUDP) and SUDEP that we and others have been positing. I think the researchers very nicely make the point that epilepsy and cardiac arrhythmia genes are not as separated in their effects as many would believe.”

As for the clinical applicability of the findings, Dr. Goldstein said medicine needs to offer parents more: “Pediatric deaths without explanation deserve more than a forensic investigation that concerns itself mostly with whether there has been foul play,” he said. “We need to figure out how to engage families, at an incredibly vulnerable time, in helping find the cause of the child’s death and also contributing to needed research. Most of the reported variants were de novo, which means that parent participation is needed to figure out these genetic factors but also that we can offer reassurance to families that other children are not at risk.”

The study was supported by the SUDC Foundation and Finding a Cure for Epilepsy and Seizures (New York University). Dr. Tsien disclosed support from the National Institutes of Health and a grant from FACES. Dr. Goldstein reported no relevant financial relationships.

Research to date has suggested links between SUDC and a family history of febrile seizures, as well as differences in brain structure associated with epilepsy, Dr. Goldstein said.

“An important hypothesis is that these deaths are part of a continuum that also includes stillbirths, SIDS, and sudden unexpected death in epilepsy [SUDEP],” Dr. Goldstein said. “By mandate, investigations of these deaths occur under the jurisdiction of medical examiners and coroners and have, for the most part, been insulated from developments in modern medicine like genomics and proteomics, elements of what are referred to as the molecular autopsy, and studies such as the current study bring attention to what is being missed.”

Dr. Goldstein said the new study buttresses the “conventional clinical suspicion” about the likely causes of SUDC, “but also strengthens the association between sudden unexpected death in pediatrics (SUDP) and SUDEP that we and others have been positing. I think the researchers very nicely make the point that epilepsy and cardiac arrhythmia genes are not as separated in their effects as many would believe.”

As for the clinical applicability of the findings, Dr. Goldstein said medicine needs to offer parents more: “Pediatric deaths without explanation deserve more than a forensic investigation that concerns itself mostly with whether there has been foul play,” he said. “We need to figure out how to engage families, at an incredibly vulnerable time, in helping find the cause of the child’s death and also contributing to needed research. Most of the reported variants were de novo, which means that parent participation is needed to figure out these genetic factors but also that we can offer reassurance to families that other children are not at risk.”

The study was supported by the SUDC Foundation and Finding a Cure for Epilepsy and Seizures (New York University). Dr. Tsien disclosed support from the National Institutes of Health and a grant from FACES. Dr. Goldstein reported no relevant financial relationships.

Mutations in genes associated with cardiac and seizure disorders appear to be linked to sudden unexplained deaths in young children and may explain nearly 9% of such cases, researchers have found.

Previous studies have found de novo genetic variants – those not found in either parent but which occur for the first time in their offspring – that increase the risk of cardiac and seizure disorders, but research on sudden unexplained deaths in children (SUDC) is limited, according to Matthew Halvorsen, PhD, of the University of North Carolina at Chapel Hill, and colleagues. Most cases of SUDC occur in children aged 1-4 years, and a lack of standardized investigation systems likely leads to misclassification of these deaths, they said.

Compared with sudden infant death syndrome (SIDS), which occurs in approximately 1,400 children in the United States each year, approximately 400 children aged 1 year and older die from SUDC annually. A major obstacle to studying these cases is that so-called molecular autopsies – which incorporate genetic analysis into the postmortem examination – typically do not assess the parents’ genetic information and thus limit the ability to identify de novo mutations, they added.

In a study published in the Proceedings of the National Academy of Sciences, Dr. Halvorsen’s group obtained whole exome sequence data from 124 “trios,” meaning a dead child and two living parents. They tested for excessive de novo mutations for different genes involved in conditions that included cardiac arrhythmias and epilepsy. The average age at the time of death for the children was 34.2 months; 54% were male, and 82% were White.

Children who died of SUDC were nearly 10 times as likely to have de novo mutations in genes associated with cardiac and seizure disorders as were unrelated healthy controls (odds ratio, 9.76). Most pathogenic variants were de novo, which highlights the importance of trio studies, the researchers noted.

The researchers identified 11 variants associated with increased risk of SUDC, 7 of which were de novo. Three of the 124 cases carried mutations (two for RYR2 and 1 for TNNI3) affecting genes in the CardiacEpilepsy dataset proposed by the American College of Medical Genetics and Genomics, strengthening the connection to seizure disorders.

Another notable finding was the identification of six de novo mutations involved in altering calcium-related regulation, which suggests a cardiac susceptibility to sudden death.

The data support “novel genetic causes of pediatric sudden deaths that could be discovered with larger cohorts,” the researchers noted. Taken together, they say, the gene mutations could play a role in approximately 9% of SUDC cases.

The study findings were limited by several factors, including lack of population-based case ascertainment, exclusive focus on unexplained deaths, potentially missed mutations, and use of DNA from blood as opposed to organs, the researchers noted.

However, they concluded, “the data indicate that deleterious de novo mutations are significant genetic risk factors for childhood sudden unexplained death, and that their identification may lead to medical intervention that ultimately saves lives.”

Findings highlight impact of SUDC

“This study is important because SUDC is a much more pressing medical need than most people realize,” said Richard Tsien, PhD, of New York University Langone Medical Center, and the corresponding author of the study.

Although SUDC is less common than SIDS, SUDC has essentially no targeted research funding, Dr. Tsien said. Study coauthor Laura Gould, MA, a researcher and mother who lost a young child to SUDC, worked with Orrin Devinsky, MD, to create a registry for families with cases of SUDC. This registry was instrumental in allowing the researchers to “do the molecular detective work we need to do” to see whether a genetic basis exists for SUDC, Dr. Tsien said.

“The detective work comes up with a consistent story,” he said. “More than half of the genes that we found are involved in the normal function of the heart and brain,” performing such functions as delivering calcium ions to the inside of the heart cells and nerve cells.

The study “is the first of its kind,” given the difficulty of acquiring DNA from the child and two parents in SUDC cases, Dr. Tsien said.

Overall, approximately 10% of the cases have a compelling explanation based on the coding of DNA, Dr. Tsien said. From a clinical standpoint, that information might affect what a clinician says to a parent.

A key takeaway is that most of the genetic mutations are spontaneous and are not inherited from the parents, Dr. Tsien said. The study findings indicate that parents who suffer an SUDC loss need not be discouraged from having children, he added.

For the long term, “the more we understand about these disorders, the more information we can offer to families,” he said. Eventually, clinicians might be able to use genetics to identify signs of when SUDC might be more likely. “For example, if a child shows a very mild seizure, this would alert them that there might be potential for a more drastic outcome.”

Meanwhile, families with SUDC cases may find support and benefit in signing up for the registry and knowing that other families have been through a similar experience, Dr. Tsien said.

Use of a leukotriene receptor antagonist (LTRA) for asthma management did not increase the risk of neuropsychiatric disease, based on data from more than 60,000 asthma patients.

Although LTRAs are established as an effective drug for asthma, the U.S. Food and Drug Administration warnings of the risk for neuropsychiatric (NP) drug reactions – including a boxed warning for montelukast (Singulair) – has raised concerns, writes Ji-Su Shim, MD, of Ewha Womans University, Seoul, South Korea, and colleagues.

However, evidence for such an association is limited, and previous studies have focused only on children and adolescents, and on a single LTRA (montelukast), the researchers say.

In a study published Dec. 1 in the Journal of Allergy and Clinical Immunology: In Practice, the researchers used a Korean national health insurance database to identify 61,571 adult patients with asthma aged 40 years and older between Jan. 2002 and Dec. 2015 with no history of LTRA use.

The patients underwent screening examinations between Jan. 2009 and Dec. 2010, which marked the start of a follow-up period ending on Dec. 31, 2015. The median age of the study population was 61 years, and the mean follow-up period for NPs or other outcomes was approximately 47.6 months for LTRA users and 46.5 months for nonusers. Overall, 11.1% of the study population used pranlukast (Onon), 11% used montelukast, and 0.24% used zafirlukast (Accolate).

A total of 12,168 patients took an LTRA during the follow-up period. The hazard ratio for newly diagnosed neuropsychiatric diseases was not significantly different between LTRA users and nonusers (hazard ratio, 1.01; P = .952) in an adjusted model that included age, sex, pack-years of smoking, alcohol use, physical activity, body mass index, comorbid conditions, other respiratory diseases, and use of other asthma medications.

The most common NPs were dementia, mood disorders, and panic disorders, and the prevalence of each was not significantly different between LTRA users and nonusers (75.4% vs. 76.1% for dementia, 12.7% vs. 12.8% for mood disorders, and 5.6% vs. 3.5% for panic disorders).

A subgroup analysis for associations between the duration of LTRA use and NP disease risk also showed no significant difference between LTRA users and nonusers.

“The mechanism of the development of NP symptoms by LTRAs has not been identified,” the researchers write in their discussion of the study findings. “Because most of NP side effects due to montelukast occur in few patients within 2 weeks of drug administration, it also may have relation with the presence of some genetic polymorphisms involving modification of the normal action or metabolism of LTRAs,” they explained.

The FDA’s boxed warning for montelukast noting the risk of serious mental health side effects has renewed interest in the relationship between NPs and LTRAs, the researchers noted. However, the current study findings support previous randomized controlled trials and larger studies, and the current warnings are based mainly on pharmacovigilance studies, case series, and case reports, they said.

The study findings were limited by several factors, including the retrospective design, the potential for misclassification of asthma diagnosis, the exclusion of temporary NP symptoms that might prompt LTRA discontinuation, and the inability to detect possible differences in ethnicities other than Korean, the researchers note.

However, the results suggest that adverse NP symptoms should not prevent physicians from prescribing LTRAs to selected patients with asthma. Instead, the physician should accompany the prescription with “a word of caution in case any mood changes might occur,” the investigators wrote.

“Further studies, such as randomized controlled trials, are needed to reveal the association between the use of LTRAs and the risk of NP events and/or diseases,” they concluded.

Potential genetic predisposition may drive cases

The relatively rare occurrence of NP symptoms in asthma patients using LTRAs has prompted questions from the medical community on whether the relationship really exists, writes Désirée Larenas-Linnemann, MD, of Médica Sur Clinical Foundation and Hospital, Mexico City, in an accompanying editorial ).

The current study provides information about medications and possible adverse drug reactions, but “great care should be taken in the interpretation of the results from such a study,” she notes. Limitations include not only the possible misclassification of asthma and the homogeneous study population, but also the fact that some NPs, such as dementia, are already common in older adults..

Dr. Larenas-Linnemann shared a story of one of her patients, a 2½-year-old boy who began exhibiting hyperactivity and other strange behaviors while on an LRTA. The toddler’s father had previously reported “horrible nightmares, strange thoughts, and to feel upset, unsecure until he suspended the medication.” Cases such as this support a potential genetic predisposition, with drug metabolism playing a role, and clinicians should take genetic backgrounds into account, she said.

“Even though the current study did not show an association between LTRA use or duration of exposure and the occurrence of NP diseases in Korean adults with asthma, this does not imply such a relationship might be present in other age groups (children-adolescents-adults up to 50 years) or in patients with a different genetic background,” she emphasized.

However, “In the meantime, although LTRA should continue to be prescribed if indicated, an index of suspicion for possible NP effects should be maintained,” Dr. Larenas-Linnemann concluded.

“This study is timely, since the boxed warning for montelukast was issued approximately 1 year ago by the FDA,” Thomas B. Casale, MD, of the University of South Florida, Tampa, said in an interview.

Dr. Casale said he was not surprised by the findings, “since most of the data implicating a potential link between the use of montelukast and neuropsychiatric disorders have not been particularly compelling,” and much of the current information comes from case reports and retrospective studies.

“Furthermore, the data appeared to be somewhat stronger in the pediatric population,” Dr. Casale noted. “This study focused on elderly patients (mean age 61) and included two other leukotriene modifiers. The number of patients receiving montelukast was small (56), which may have also confounded the results,” he noted.

As for clinical implications, “I don’t think this study will change practice,” Dr. Casale said. “As indicated, it is in an elderly population, included only a limited number of patients receiving montelukast, and was in a Korean cohort. All of these factors could have influenced the results,” and the data may not be generalizable to patients elsewhere, including the United States, he said. “Also, the study only included patients with asthma and in the United States; the approval for rhinitis is another important indication to study,” he noted.

Additional research is needed in the form of better prospective studies examining the potential link between montelukast and neuropsychiatric disorders in both the pediatric and adult populations having either asthma or rhinitis, Dr. Casale concluded.

The study received no outside funding. The researchers and Dr. Casale have disclosed no relevant financial relationships. Dr. Larenas-Linnemann disclosed personal fees from Allakos, Armstrong, AstraZeneca, Chiesi, DBV Technologies, Grünenthal, GSK, Mylan/Viatris, Menarini, MSD, Novartis, Pfizer, Sanofi, Siegfried, UCB, Alakos, Gossamer, and Carnot, and grants from Sanofi, AstraZeneca, Novartis, Circassia, UCB, GSK, and the Purina Institute.

The Food and Drug Administration has accepted a new drug application (NDA) for roflumilast, a topical phosphodiesterase type 4 (PDE4) inhibitor for treating psoriasis in adults and adolescents, according to a statement from the manufacturer.

Roflumilast cream (also known as ARQ-151) is a small molecule inhibitor of PDE4, an enzyme that increases proinflammatory mediators and decreases anti-inflammatory mediators. PDE4 is an established treatment target in dermatology: The FDA approved PDE-4 inhibitor crisaborole (Eucrisa) as a topical treatment for mild to moderate atopic dermatitis in 2016, and an oral PDE-4 inhibitor, orismilast, is being studied for the treatment of plaque psoriasis.

Topical roflumilast, if approved, would be the first topical PDE4 inhibitor for psoriasis in particular, according to the Arcutis Biotherapeutics statement. The cream is designed for use on the entire body, including the face and sensitive intertriginous areas.

The NDA is based on data from a pair of phase 3 randomized, double-blind 8-week studies known as DERMIS 1 and DERMIS 2 (Trials of PDE4 Inhibition with Roflumilast for the Management of Plaque Psoriasis” One and Two) and a long-term phase 2b open-label study.

DERMIS 1 and DERMIS 2 were identical multinational, multicenter studies designed to assess the safety and efficacy of 0.3% roflumilast cream. In the studies, roflumilast met its primary endpoint and patients treated with it demonstrated an Investigator Global Assessment (IGA) success rate of 42.4% compared with 6.1% for the vehicle control (P < .0001), and 37.5% compared with 6.9% for the vehicle control (P < .0001), in the DERMIS 1 and 2 trials, respectively, according to Arcutis.

In the phase 2b study, the treatment effect lasted for 52-64 weeks. Roflumilast was well tolerated across the three studies.

Overall, the most common adverse events reported in the studies were diarrhea (3%), headache (2%), insomnia (1%), nausea (1%), upper respiratory tract infections (1%), and urinary tract infections (1%).

Roflumilast also showed statistically significant improvement compared to a vehicle on secondary endpoints including Intertriginous IGA (I-IGA) Success, Psoriasis Area Severity Index-75 (PASI-75), reductions in itch as measured by the Worst Itch-Numerical Rating Scale (WI-NRS), and patient perceptions of symptoms based on the Psoriasis Symptoms Diary (PSD).

The FDA has set a Prescription Drug User Fee Act (PDUFA) target action date of July 29, 2022, according to the manufacturer’s statement. An oral formulation of roflumilast was approved by the FDA in 2011, for reducing the risk of exacerbations of chronic obstructive pulmonary disease (COPD) in patients with severe COPD.

The Food and Drug Administration has accepted a new drug application (NDA) for roflumilast, a topical phosphodiesterase type 4 (PDE4) inhibitor for treating psoriasis in adults and adolescents, according to a statement from the manufacturer.

Roflumilast cream (also known as ARQ-151) is a small molecule inhibitor of PDE4, an enzyme that increases proinflammatory mediators and decreases anti-inflammatory mediators. PDE4 is an established treatment target in dermatology: The FDA approved PDE-4 inhibitor crisaborole (Eucrisa) as a topical treatment for mild to moderate atopic dermatitis in 2016, and an oral PDE-4 inhibitor, orismilast, is being studied for the treatment of plaque psoriasis.

Topical roflumilast, if approved, would be the first topical PDE4 inhibitor for psoriasis in particular, according to the Arcutis Biotherapeutics statement. The cream is designed for use on the entire body, including the face and sensitive intertriginous areas.

The NDA is based on data from a pair of phase 3 randomized, double-blind 8-week studies known as DERMIS 1 and DERMIS 2 (Trials of PDE4 Inhibition with Roflumilast for the Management of Plaque Psoriasis” One and Two) and a long-term phase 2b open-label study.

DERMIS 1 and DERMIS 2 were identical multinational, multicenter studies designed to assess the safety and efficacy of 0.3% roflumilast cream. In the studies, roflumilast met its primary endpoint and patients treated with it demonstrated an Investigator Global Assessment (IGA) success rate of 42.4% compared with 6.1% for the vehicle control (P < .0001), and 37.5% compared with 6.9% for the vehicle control (P < .0001), in the DERMIS 1 and 2 trials, respectively, according to Arcutis.

In the phase 2b study, the treatment effect lasted for 52-64 weeks. Roflumilast was well tolerated across the three studies.

Overall, the most common adverse events reported in the studies were diarrhea (3%), headache (2%), insomnia (1%), nausea (1%), upper respiratory tract infections (1%), and urinary tract infections (1%).

Roflumilast also showed statistically significant improvement compared to a vehicle on secondary endpoints including Intertriginous IGA (I-IGA) Success, Psoriasis Area Severity Index-75 (PASI-75), reductions in itch as measured by the Worst Itch-Numerical Rating Scale (WI-NRS), and patient perceptions of symptoms based on the Psoriasis Symptoms Diary (PSD).

The FDA has set a Prescription Drug User Fee Act (PDUFA) target action date of July 29, 2022, according to the manufacturer’s statement. An oral formulation of roflumilast was approved by the FDA in 2011, for reducing the risk of exacerbations of chronic obstructive pulmonary disease (COPD) in patients with severe COPD.

Spesolimab, a humanized, anti–interleukin-36 receptor monoclonal antibody, was associated with rapid improvement in pustules during flares, in a phase 2 study of 53 adults with generalized pustular psoriasis (GPP).

GPP is a life-threatening skin condition involving the widespread eruption of sterile pustules, with a clinical course that “can be relapsing with recurrent flares or persistent with intermittent flares,” Hervé Bachelez, MD, of the Université de Paris and coauthors wrote. GPP patients are often hospitalized, and mortality ranges from 2% to 16% from causes that include sepsis and cardiorespiratory failure.

“The role of the interleukin-36 pathway in GPP is supported by the finding of loss-of-function mutations in the interleukin-36 receptor antagonist gene (IL36RN) and associated genes (CARD14, AP1S3, SERPINA3, and MPO) and by the overexpression of interleukin-36 cytokines in GPP skin lesions,” therefore, IL-36 is a potential treatment target to manage flares, they explained.

In the multicenter, double-blind trial, published in the New England Journal of Medicine, the researchers randomized 35 adults with GPP flares to a single 900-mg intravenous dose of spesolimab and 18 to placebo. Patients in both groups could receive an open-label dose of spesolimab after day 8; all patients were followed for 12 weeks.

The primary study endpoint was the Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 at 1 week after treatment. The GPPGA ranges from 0 (no visible pustules) to 4 (severe pustules). At baseline, 46% spesolimab patients and 39% placebo patients had a GPPGA pustulation subscore of 3, and 37% and 33%, respectively, had a pustulation subscore of 4.

After 1 week, 54% of the spesolimab patients had no visible pustules, compared with 6% of placebo patients; the difference was statistically significant (P < .001). The main secondary endpoint was a score of 0 or 1 (clear or almost clear skin) on the GPPGA total score after 1 week. Significantly more spesolimab patients had GPPGA total scores of 0 or 1, compared with placebo patients (43% vs. 11%, respectively; P = .02).

Overall, 6 of 35 spesolimab patients (17%) and 6% of those in the placebo groups developed infections during the first week, and 24 of 51 patients (47%) who had received spesolimab at any point during the study developed infections by week 12. Infections included urinary tract infections (three cases), influenza (three), otitis externa (two), folliculitis (two), upper respiratory tract infection (two), and pustule (two).

In the first week, 6% of spesolimab patients and none of the placebo patients reported serious adverse events; at week 12, 12% of patients who had received at least one spesolimab dose reported a serious adverse event. In addition, antidrug antibodies were identified in 23 (46%) of the 50 patients who received at least one dose of spesolimab.

“Symptoms that were observed in two patients who received spesolimab were reported as a drug reaction with eosinophilia and systemic symptoms (DRESS),” the authors noted. One patient had a RegiSCAR (European Registry of Severe Cutaneous Adverse Reactions) score and the other had a score of 3; a score below 2 indicates no DRESS, and a score of 2 or 3 indicates “possible DRESS,” they added.

“Because 15 of the 18 patients who were assigned to the placebo group received open-label spesolimab, the effect of spesolimab as compared with that of placebo could not be determined after week 1,” the researchers noted.

The study findings were limited by several factors including the short randomization period and small study population, the researchers noted. However, the effect sizes for both the primary and secondary endpoints were large, which strengthened the results.

The results support data from previous studies suggesting a role for IL-36 in the pathogenesis of GPP, and support the need for longer and larger studies of the safety and effectiveness of spesolimab for GPP patients, they concluded.

No FDA-approved therapy

“GPP is a very rare but devastating life-threatening disease that presents with the sudden onset of pustules throughout the skin,” Joel Gelfand, MD, professor of dermatology and director of the psoriasis and phototherapy center at the University of Pennsylvania, Philadelphia, said in an interview. “Without rapid treatment, GPP can result in death. Currently there are no [Food and Drug Administration]–approved treatments for this orphan disease.”

Dr. Gelfand said he was surprised by the degree of efficacy and the speed of the patient response to spesolimab, compared with placebo, which he described as “truly remarkable.” Based on the current study results, “spesolimab offers a tremendous step forward for our patients,” he added. 

Looking ahead, Dr. Gelfand noted that “longer-term studies with a comparator, such as a biologic that targets IL-17, would be helpful to more fully understand the safety, efficacy, and role that spesolimab will have in real-world patients.”

On Dec. 15, Boehringer Ingelheim announced that the FDA had granted priority review for spesolimab for treating GPP flares.

The study was supported by Boehringer Ingelheim. Lead author Dr. Bachelez had no financial conflicts to disclose. Several authors are employees of Boehringer Ingelheim. Dr. Gelfand is a consultant for the study sponsor Boehringer Ingelheim and has received research grants from Boehringer Ingelheim to his institution to support an investigator-initiated study. He also disclosed serving as a consultant and receiving research grants from other manufacturers of psoriasis products.

Field cancerization and subsequent second cancer in squamous cell carcinoma (SCC) patients was significantly associated with cigarette and alcohol use, based on data from more than 300 individuals.

Cigarette and alcohol use are established risk factors for SCCs of the esophagus, head, and neck, Manabu Moto, MD, of Kyoto University, and colleagues wrote. “In addition, squamous cell carcinoma and squamous dysplastic epithelium develop multifocally in these organs,” in a phenomenon known as field cancerization, but the interaction of multiple dysplastic epithelium with other factors, notably whether cessation of cigarette and alcohol use would reduce risk of SCC, has not been well studied.

In a study published in Gastro Hep Advances, the researchers identified 331 adults with newly diagnosed superficial esophageal SCC who underwent endoscopic resection, and 1,022 healthy controls. Field cancerization was based on the number of Lugol-voiding lesions (LVLs) per endoscopic view according to three groups: grade A, 0 LVLs; grade B, 1-9; or grade C, at least 10. The primary study outcome was a measure of risk factors for the development of LVLs.

“Multiple LVLs are closely associated with inactive aldehyde dehydrogenase 2 (ALDH2) and field cancerization,” the researchers wrote. Before assessing their human subjects, they used a mouse model to investigate whether alcohol intake and abstinence would affect acetaldehyde-induced DNA damage to the esophageal epithelium among individuals with ALDH2 dysfunction.

The researchers found that DNA damage, measured by acetaldehyde-derived DNA adduct levels (via N²-ethylidene-dG), accumulated with alcohol consumption over time, but decreased with alcohol cessation in the mouse model.

For the human part of the study, participants completed a lifestyle survey at entry, with questions about alcohol consumption history, alcohol flushing response, smoking, consumption of high-temperature foods, and consumption of green and yellow vegetables and fruit. Drinking status was divided into five groups: never/rarely (of less than 1 unit/week), light (1-8.9 units/week), moderate (9-17.9 units/week), heavy (18 or more units/week), and ex-drinker, with 1 unit defined as 22 g of ethanol. Smoking was divided into three groups: never (0 pack-years), light (less than 30 pack-years), and heavy (30 or more pack-years). Patients were given educational materials at study entry about the importance of alcohol and smoking cessation, as well as verbal advice to cease these behaviors.

Participants underwent endoscopic surveillance at 3-month intervals for up to 6 months following endoscopic resection.

Overall, increased alcohol consumption was associated with increased risk in development of LVL across all LVL grades; higher grades of LVLs were positively associated with high-intensity alcohol consumption, smoking, flushing, and high-temperature foods, and negatively associated with eating vegetables and fruit.

The risk of LVL grade progression was most strongly associated with increased alcohol consumption and with reported flushing. “The greatest risk was observed in the patients with flushing reactions who consumed an average of 30 units per week in grade C LVL,” with an odds ratio of 534, compared with healthy controls. “Since flushing reaction is caused by accumulation of acetaldehyde due to ALDH2 deficient, our result also means that acetaldehyde is a strong carcinogen in field cancerization.”

Secondary outcomes included the incidence of second primary esophageal SCC and head/neck SCC; these were significantly more prevalent in patients with grade C LVL (cumulative 5-year incidence of 47.1% for ESCC and 13.3% for head and neck SCC). However, alcohol and smoking cessation significantly reduced the development of second primary esophageal SCC (adjusted hazard ratios, 0.47 for alcohol and 0.49 for smoking).

The study findings were limited by several factors including the lack of randomization to noncessation and cessation groups and the inclusion of cancer patients, but not long-term cancer survivors, the researchers noted.

“We believe that our data will be useful to establish a prevention and surveillance strategy for cancer survivors, because the overall prognosis of esophageal cancer and head and neck cancer is still poor,” with a 5-year survival rate of less than 20%, and the results highlight the need to educate cancer survivors on the value of smoking and alcohol cessation, they added.

The study was supported by the National Cancer Center Research and Development Fund 36 by the Ministry of Health, Labour, and Welfare of Japan. The researchers had no financial conflicts to disclose.

However, alcohol and smoking cessation significantly reduced the development of second primary esophageal SCC (adjusted hazard ratios, 0.47 for alcohol and 0.49 for smoking).

The study findings were limited by several factors including the lack of randomization to noncessation and cessation groups and the inclusion of cancer patients, but not long-term cancer survivors, the researchers noted.

“We believe that our data will be useful to establish a prevention and surveillance strategy for cancer survivors, because the overall prognosis of esophageal cancer and head and neck cancer is still poor,” with a 5-year survival rate of less than 20%, and the results highlight the need to educate cancer survivors on the value of smoking and alcohol cessation, they added.

The study was supported by the National Cancer Center Research and Development Fund 36 by the Ministry of Health, Labour, and Welfare of Japan. The researchers had no financial conflicts to disclose.
