Aspirin exposure fails to reduce cardiovascular event risk
The benefits of aspirin use for the primary prevention of atherosclerotic cardiovascular disease (ASCVD) have been questioned in light of data showing neutral outcomes in low-risk patients and concerns about increased bleeding risk and mortality in healthy older adults, wrote Rita Del Pinto, MD, of University of L’Aquila (Italy) and colleagues in JAMA Network Open.
In the study, Dr. Del Pinto and colleagues conducted a post hoc analysis of data from more than 2,500 participants in SPRINT (Systolic Blood Pressure Intervention Trial), a multicenter, randomized trial conducted from 2010 to 2013.
The goal of SPRINT was to compare intensive and standard blood pressure–lowering strategies for hypertension patients. The primary outcome of the current study was risk of a first cardiovascular event, which included adjudicated myocardial infarction, non–myocardial infarction acute coronary syndrome, stroke, acute heart failure, and CVD death.“There has been considerable improvement in the management of cardiovascular risk factors since the first reports on aspirin use for cardiovascular prevention,” Dr. Del Pinto said in an interview.
“As for hypertension, not only have more effective antihypertensive medications become available, but also evidence has recently emerged in support of a downwards redefinition of blood pressure targets during treatment,” she said. “In this context, in an era when great attention is paid to the personalization of treatment, no specific studies had addressed the association of aspirin use as a primary prevention strategy in a cohort of relatively old, high-risk individuals with treated systolic blood pressure steadily below the recommended target,” she added.
The researchers assessed whether aspirin use in addition to standard blood pressure management (a target of less than 140 mm Hg) decreased risk and improved survival.
The study population included 2,664 adult patients; 29.3% were women, and 24.5% were aged 75 years and older. Half of the patients (1,332) received aspirin and 1,332 did not.
In a multivariate analysis, 42 cardiovascular events occurred in the aspirin group, compared with 20 events in those not exposed to aspirin (hazard ratio, 2.30). The findings were consistent in subgroup analyses of younger individuals, current and former smokers, and patients on statins.
An additional subgroup analysis of individuals randomized to standard care or intensive care in the SPRINT study showed no significant difference in primary outcome rates between individuals who received aspirin and those who did not. The rates for aspirin use vs. non–aspirin use were 5.85% vs. 3.60% in the standard treatment group and 4.66% vs. 2.56% in the intensive treatment group.
The study findings were limited by several factors, including the post hoc design, short follow-up period, and lack of data on the initiation of aspirin and bleeding events, the researchers wrote. However, the results suggest that modern management of hypertension may have redefined the potential benefits of aspirin in patients with hypertension, they concluded.
Findings confirm value of preventive care
“The study was conducted as a post-hoc analysis on an experimental cohort, which must be considered when interpreting the results,” Dr. Del Pinto said.
Despite the limitations, the study findings affirm that effective treatment of major cardiovascular risk factors, such as hypertension, with proven drugs is “a mainstay of the primary prevention of ASCVD,” she emphasized.
As for additional research, “Testing our findings in a dedicated setting with sufficiently long follow-up, where aspirin dose and indication, as well as any possible bleeding event, are reported could expand the clinical meaning of our observations,” said Dr. Del Pinto. “Also, the clinical impact of aspirin, even in combination with novel cardiovascular drugs such as direct oral anticoagulants, in populations exposed to combinations of risk factors, deserves further investigation.”
Data support shared decision-making
“While recent evidence has not shown a benefit of aspirin in the primary prevention of ASCVD in several populations, the subpopulation of patients with hypertension as an ASCVD risk factor is also of interest to the clinician,” Suman Pal, MD, of the University of New Mexico, Albuquerque, said in an interview. “The lack of benefit of aspirin in this study, despite its limitations, was surprising, and I would be eager to see how the role of aspirin in ASCVD prevention would continue to evolve in conjunction with improvement in other therapies for modification of risk factors.”
“The decision to continue aspirin in this subgroup of patients should warrant a discussion with patients and a reexamination of risks and benefits until further data are available,” Dr. Pal emphasized.
Larger studies with long-term follow-ups would be required to further clarify the role of aspirin in primary prevention of ASCVD in patients with hypertension without diabetes or chronic kidney disease, he added.

Denosumab boosts bone strength in glucocorticoid users
Bone strength and microarchitecture remained stronger at 24 months after treatment with denosumab compared to risedronate, in a study of 110 adults using glucocorticoids.
Patients using glucocorticoids are at increased risk for vertebral and nonvertebral fractures at both the start of treatment or as treatment continues, wrote Piet Geusens, MD, of Maastricht University, the Netherlands, and colleagues.
Imaging data collected via high-resolution peripheral quantitative computed tomography (HR-pQCT) allow for the assessment of bone microarchitecture and strength, but specific data comparing the impact of bone treatment in patients using glucocorticoids are lacking, they said.
In a study published in the Journal of Bone and Mineral Research, the researchers identified a subset of 56 patients randomized to denosumab and 54 to risedronate patients out of a total of 590 patients who were enrolled in a phase 3 randomized, controlled trial of denosumab vs. risedronate for bone mineral density. The main results of the larger trial – presented at EULAR 2018 – showed greater increases in bone strength with denosumab over risedronate in patients receiving glucocorticoids.
In the current study, the researchers reviewed HR-pQCT scans of the distal radius and tibia at baseline, 12 months, and 24 months. Bone strength and microarchitecture were defined in terms of failure load (FL) as a primary outcome. Patients also were divided into subpopulations of those initiating glucocorticoid treatment (GC-I) and continuing treatment (GC-C).
Baseline characteristics were mainly balanced among the treatment groups within the GC-I and GC-C categories.
Among the GC-I patients, in the denosumab group, FL increased significantly from baseline to 12 months at the radius at tibia (1.8% and 1.7%, respectively) but did not change significantly in the risedronate group, which translated to a significant treatment difference between the drugs of 3.3% for radius and 2.5% for tibia.
At 24 months, the radius measure of FL was unchanged from baseline in denosumab patients but significantly decreased in risedronate patients, with a difference of –4.1%, which translated to a significant between-treatment difference at the radius of 5.6% (P < .001). Changes at the tibia were not significantly different between the groups at 24 months.
Among the GC-C patients, FL was unchanged from baseline to 12 months for both the denosumab and risedronate groups. However, FL significantly increased with denosumab (4.3%) and remained unchanged in the risedronate group.
The researchers also found significant differences between denosumab and risedronate in percentage changes in cortical bone mineral density, and less prominent changes and differences in trabecular bone mineral density.
The study findings were limited by several factors including the use of the HR-pQCT scanner, which limits the measurement of trabecular microarchitecture, and the use of only standard HR-pQCT parameters, which do not allow insight into endosteal changes, and the inability to correct for multiplicity of data, the researchers noted.
However, the results support the superiority of denosumab over risedronate for preventing FL and total bone mineral density loss at the radius and tibia in new glucocorticoid users, and for increasing FL and total bone mineral density at the radius in long-term glucocorticoid users, they said.
Denosumab therefore could be a useful therapeutic option and could inform decision-making in patients initiating GC-therapy or on long-term GC-therapy, they concluded.

TNF inhibitor treatment models promote personalized care in ankylosing spondylitis
A small number of patient and physician-reported outcomes, as well as laboratory and clinical factors, may help to predict the response of patients with ankylosing spondylitis (AS) to treatment with tumor necrosis factor (TNF) inhibitors when they have never taken them before, according to an analysis of data from nearly 2,000 individuals in 10 clinical trials.
TNF inhibitors are recommended for patients with AS whose symptoms persist despite use of NSAIDs, Runsheng Wang, MD, adjunct assistant professor at Columbia University Medical Center, New York, and a practicing rheumatologist at Garden State Rheumatology Consultants, Union, N.J., and colleagues wrote. Randomized, controlled clinical trials have shown that TNF inhibitors are effective in treating AS, but approximately half of patients fail to achieve notable improvement, which suggests the need for a predictive model.
“In clinical practice, before starting a treatment, physicians and patients want to know how likely a patient would be to respond to the treatment, particularly when more than one treatment option is available,” Dr. Wang said in an interview. “In this study, we developed predictive models that can potentially answer this question.”
The results suggest that the models in the study can be used to personalize clinical decision-making for patients with AS, whether to promote confidence in choosing a TNF inhibitor or to terminate treatment in nonresponders who had a higher probability of nonresponse at baseline, the researchers wrote. Similar models for other biologic treatments can help prioritize treatment options.
The predictive models are practical for clinical use because the variables in the reduced models – can be collected easily during patient visits, Dr. Wang explained. However, data from clinical practice are needed to further validate the study findings.
In a retrospective cohort study published in JAMA Network Open, the researchers analyzed data from 10 randomized, controlled clinical trials of TNF inhibitor treatment in patients with active AS conducted during 2002-2016. The study population included 1,899 adults with active AS who received an originator TNF inhibitor for at least 12 weeks, and the training set included 1,207 individuals. In the training set, the mean age of the participants was 39 years, and 75% were men.
The outcomes included major response and no response based on change in AS Disease Activity Score (ASDAS) from baseline to 12 weeks, and the researchers used machine-learning algorithms to estimate the probability of major response or no response. Major response was defined as a decrease in ASDAS of 2.0 or greater; no response was defined as a decrease in ASDAS of less than 1.1.
In the training set, a total of 407 patients (33.7%) had a major response, and 414 (34.3%) had no response.
The key features in the full, 21-variable model that increased the probability of a major response were higher C-reactive protein (CRP) levels, higher patient global assessment (PGA) of disease activity, and Bath AS Disease Activity Index (BASDAI) question 2 scores. (Question 2 asks for the overall level of back, hip, or neck pain associated with AS.) The probability of a major response decreased with higher body mass index and Bath AS Functional Index (BASFI) scores.
The key features in the model that increased the probability of no response were older age and higher BASFI scores. The probability of no response decreased with higher CRP levels, higher BASDAI question 2 scores, and higher PGA scores.
Overall, the researchers found that models using smaller subsets of variables (three or five variables in total) that would be easier to gather clinically yielded similar predictive performance.
The models were externally validated in a testing set of 692 individuals. Baseline characteristics were similar in the testing and training sets. In the testing set, the full models demonstrated moderate to high accuracy of 0.71 in the random forest model for major response and 0.76 in the random forest model for no response, with similar results in the reduced models.
At a prevalence of 25% for major response, the positive predictive values (PPVs) for random forest and logistic regression models ranged from 0.49 to 0.60, and the negative predictive values (NPVs) ranged from 0.82 to 0.84. At a prevalence of 25% for no response, PPVs ranged from 0.61 to 0.77, and NPVs ranged from 0.81 to 0.83.
The study findings were limited by several factors including the lack of data on smoking, which has been linked both to shorter treatment adherence and worse response to TNF inhibitors; the inclusion of only TNF inhibitor–naive patients; and the exclusion of NSAIDs from the models, the researchers wrote.
Dr. Wang disclosed support from the Rheumatology Research Foundation. The study’s two other authors disclosed receiving support from the Intramural Research Program of the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The study was based on an analysis of data from AbbVie and Pfizer that were made available through Vivli.

Randomized, controlled clinical trials have shown that TNF inhibitors are effective in treating AS, but approximately half of patients fail to achieve notable improvement, which suggests the need for a predictive model.
“In clinical practice, before starting a treatment, physicians and patients want to know how likely a patient would be to respond to the treatment, particularly when more than one treatment option is available,” Dr. Wang said in an interview. “In this study, we developed predictive models that can potentially answer this question.”
The results suggest that the models in the study can be used to personalize clinical decision-making for patients with AS, whether to promote confidence in choosing a TNF inhibitor or to terminate treatment in nonresponders who had a higher probability of nonresponse at baseline, the researchers wrote. Similar models for other biologic treatments can help prioritize treatment options.
The predictive models are practical for clinical use because the variables in the reduced models – can be collected easily during patient visits, Dr. Wang explained. However, data from clinical practice are needed to further validate the study findings.
In a retrospective cohort study published in JAMA Network Open, the researchers analyzed data from 10 randomized, controlled clinical trials of TNF inhibitor treatment in patients with active AS conducted during 2002-2016. The study population included 1,899 adults with active AS who received an originator TNF inhibitor for at least 12 weeks, and the training set included 1,207 individuals. In the training set, the mean age of the participants was 39 years, and 75% were men.
The outcomes included major response and no response based on change in AS Disease Activity Score (ASDAS) from baseline to 12 weeks, and the researchers used machine-learning algorithms to estimate the probability of major response or no response. Major response was defined as a decrease in ASDAS of 2.0 or greater; no response was defined as a decrease in ASDAS of less than 1.1.
In the training set, a total of 407 patients (33.7%) had a major response, and 414 (34.3%) had no response.
The key features in the full, 21-variable model that increased the probability of a major response were higher C-reactive protein (CRP) levels, higher patient global assessment (PGA) of disease activity, and Bath AS Disease Activity Index (BASDAI) question 2 scores. (Question 2 asks for the overall level of back, hip, or neck pain associated with AS.) The probability of a major response decreased with higher body mass index and Bath AS Functional Index (BASFI) scores.
The key features in the model that increased the probability of no response were older age and higher BASFI scores. The probability of no response decreased with higher CRP levels, higher BASDAI question 2 scores, and higher PGA scores.
Overall, the researchers found that models using smaller subsets of variables (three or five variables in total) that would be easier to gather clinically yielded similar predictive performance.
The models were externally validated in a testing set of 692 individuals. Baseline characteristics were similar in the testing and training sets. In the testing set, the full models demonstrated moderate to high accuracy of 0.71 in the random forest model for major response and 0.76 in the random forest model for no response, with similar results in the reduced models.
At a prevalence of 25% for major response, the positive predictive values (PPVs) for random forest and logistic regression models ranged from 0.49 to 0.60, and the negative predictive values (NPVs) ranged from 0.82 to 0.84. At a prevalence of 25% for no response, PPVs ranged from 0.61 to 0.77, and NPVs ranged from 0.81 to 0.83.
The study findings were limited by several factors including the lack of data on smoking, which has been linked both to shorter treatment adherence and worse response to TNF inhibitors; the inclusion of only TNF inhibitor–naive patients; and the exclusion of NSAIDs from the models, the researchers wrote.
Dr. Wang disclosed support from the Rheumatology Research Foundation. The study’s two other authors disclosed receiving support from the Intramural Research Program of the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The study was based on an analysis of data from AbbVie and Pfizer that were made available through Vivli.

Adolescents are undertested for STIs
Approximately 20% of sexually active high schoolers reported testing for a sexually transmitted infection in the previous year, based on data from 2,501 respondents to the 2019 national Youth Risk Behavior Survey.
Data suggest that half of all new STIs in the United States occur in youth aged 15-24 years, and that 25% of sexually active young women in the United States have an STI, wrote Nicole Liddon, PhD, of the Centers for Disease Control and Prevention, Atlanta, and colleagues.
Although organizations including the American Academy of Pediatrics and the U.S. Preventive Services Task Force recommend varying degrees of routine STI screening for adolescents, data on the prevalence of testing in this population are limited, the researchers said.
However, the addition in 2019 of a question on STI testing to the national Youth Risk Behavior Survey (YRBS) provided an opportunity to assess prevalence of STI testing, identify potential barriers, and increase screening rates, they wrote.
In a study published in Pediatrics, the researchers reviewed data from the 2019 national YRBS, an anonymous survey administered biannually to public and private high school students across the United States.
The study population included 2,501 individuals who reported sexual activity with at least one person during the 3 months prior to the survey.
Overall, 20.4% of the respondents reported being tested for an STI in the previous year, including significantly more females than males (26.1% vs. 13.7%).
The prevalence of testing among females was not significantly different according to race/ethnicity, sexual identity, or the sex of sexual contacts, but the prevalence increased with age; 12.6%, 22.8%, 28.5%, and 36.9% for females aged 15 years and younger, 16 years, 17 years, and 18 years, respectively.
Among males, no significant differences in STI testing were noted according to race/ethnicity, age, sexual identity, or sex of sexual contacts.
The researchers also analyzed prevalence of STI tested based on sexual behaviors. Among female students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: nonuse of condoms at last sexual intercourse (34.1% vs. 18.2%), substance use at last sexual intercourse (32.0% vs. 24.7%), and having four or more lifetime sex partners (31.9% vs. 24.7%).
Among male students, the prevalence of STI testing was higher among those who reported the following behaviors, compared with those who did not: sex before age 13 years (27.1% vs. 12.1%), having two or more recent sex partners (22.4% vs. 10.4%), having four or more lifetime sex partners (22.3% vs. 9.5%), and substance use at last sexual intercourse (19.2% vs. 12.1%).
The low prevalence of STI testing in teens has become more urgent in the wake of the coronavirus pandemic, the researchers wrote. “These prevalence estimates were derived before the possible profound impacts of the pandemic on adolescent sexual behavior and access to and use of health care services.”
Current guidelines allow health care providers the options for opt-out STI screening as a strategy to improve screening rates and testing; however, this option does not eliminate the need for conversations with adolescent patients about sexual activity, they emphasized.
The study findings were limited by several other factors including the inability to directly assess adherence to screening recommendations specifically, the inability to determine whether low testing rates resulted from limited access to health care or missed screening opportunities at visits, and the inclusion only of high school students but not out-of-school youth who may have more limited access to testing.
However, the results highlight the need to improve STI testing services for adolescents, and to address barriers at the individual and clinic level, they said. The addition of a question about past-year STI testing to the 2019 and future YRBS survey will promote ongoing monitoring of efforts to increase testing rates.
Teen sexual health goes beyond testing
The current study shows that routine testing for STIs according to published guidelines is low, Cynthia Holland-Hall, MD, and Andrea E. Bonny, MD, of Nationwide Children’s Hospital and Ohio State University, both in Columbus, wrote in an accompanying editorial.
Notably, sexually active females and males who had sex with male partners, two groups for whom annual testing is specifically recommended by multiple organizations, had testing rates of less than 30%, they said. The authors highlighted the study’s lack of information on which specific barriers, such as lack of access to the health care system, lack of knowledge, and fear of disclosure, contributed to overall low rates of testing.
However, STI testing is only one element of sexual and reproductive health care. Although opt-out testing may improve detection rates, the editorialists emphasized the need for patient-provider conversations about sex, citing recent studies showing that adolescents who spent some time alone with providers were more likely to receive sexual and reproductive health (SRH) services in the past year.
“Resources such as confidentiality policies, checklists, and written screening tools may facilitate SRH discussions,” Dr. Holland-Hall and Dr. Bonny said. “With a little practice, respect, and intention, a caring provider can take the awkward out of discussing sexual health but must not opt out of the conversation.”
Privacy and time issues exacerbate low testing rates
The current study is especially important at this time because many adolescents have likely missed well visits, and therefore important STI screens, because of disruptions caused by the COVID-19 pandemic, Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn., said in an interview.
“I was surprised that the rate of screening was only one in five,” said Dr. Kinsella. “I knew it would be suboptimal, but not that low.”
According to Dr. Kinsella, there are two major barriers to increasing STI testing in adolescents in primary care. One barrier is that insurance companies will often state on the bill what the testing was for, which will lead to an uncomfortable conversation at a later date for the adolescent and parent when the bill arrives in the mail. A second barrier is when to test during a visit,. “If we obtain urine samples on all adolescents and many of them are not sexually active, we are wasting a lot of time in the short visit to obtain urine,” she explained. “If testing is scheduled for the end of the visit, they often leave without providing a urine sample.”
Overall, the study is an important reminder to general pediatricians about STI testing for sexually active teens, she emphasized.
The study received no outside funding. The researchers had no financial conflicts to disclose. The editorialists had no financial conflicts to disclose. Dr. Kinsella had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Restless legs syndrome occurs often in X-linked adrenoleukodystrophy
Patients with X-linked adrenoleukodystrophy (ALD), a neurodegenerative disease, often experience gait and balance problems, as well as leg discomfort, sleep disturbances, and pain, wrote John W. Winkelman, MD, of Massachusetts General Hospital, Boston, and colleagues. Restless legs syndrome (RLS) has been associated with neurological conditions including Parkinson’s disease, but the prevalence of RLS in ALD patients has not been examined, they said.
In a pilot study published in Sleep Medicine, the researchers identified 21 women and 11 men with ALD who were treated at a single center. The median age of the patients was 45.9 years. Twenty-seven patients had symptoms of myelopathy, with a median age of onset of 34 years.
The researchers assessed RLS severity using questionnaires and the Hopkins Telephone Diagnostic Interview (HTDI), a validated RLS assessment tool. They also reviewed patients’ charts for data on neurological examinations, functional gait measures, and laboratory assessments. Functional gait assessments included the 25-Foot Walk test (25-FW), the Timed Up and Go test (TUG), and Six Minute Walk test (6MW).
Thirteen patients (10 women and 3 men) met criteria for RLS based on the HTDI. The median age of RLS onset was 35 years. Six RLS patients (46.2%) reported using medication to relieve symptoms, and eight RLS patients had a history of antidepressant use.
In addition, six patients with RLS reported a history of anemia or iron deficiency. Ferritin levels were available for 14 patients: 8 women with RLS and 4 women and 2 men without RLS; the mean ferritin levels were 74.0 mcg/L in RLS patients and 99.5 mcg/L in those without RLS.
Of the seven ALD patients with brain lesions, all were men, only two were diagnosed with RLS, and all seven cases were mild, the researchers noted.
Overall, patients with RLS had more neurological signs and symptoms than those without RLS; the most significant were pain and gait difficulty. However, patients with RLS also were more likely than were those without RLS to report spasticity, muscle weakness, impaired coordination, hyperreflexia, impaired sensation, and paraesthesia, as well as bladder, bowel, and erectile dysfunction.
The 40.6% prevalence of RLS in patients with ALD is notably higher than that of the general population, in which the prevalence of RLS is 5%-10%, the researchers wrote in their discussion.
“Consistent with patterns observed in the general population, risk factors for RLS in this cohort of adults with ALD included female gender, increased age, lower iron indices, and use of serotonergic antidepressants,” they said.
The study findings were limited by several factors including the small size and the possible contribution of antidepressant use to the high rate of RLS, the researchers noted.
“Awareness of RLS in patients with ALD would allow for its effective treatment, which may improve the functional impairments as well as quality of life, mood, and anxiety issues in those with ALD,” they concluded.
The study received no outside funding.
Dr. Winkelman disclosed ties with Advance Medical, Avadel, Disc Medicine, Eisai, Emalex, Idorsia, Noctrix, UpToDate, and Merck Pharmaceuticals, as well as research support from the National Institute on Drug Abuse and the Baszucki Brain Research Foundation.

Pneumonia shows strong connection to chronic otitis media
Individuals with a prior diagnosis of pneumonia were significantly more likely to develop chronic otitis media (COM) than were those without a history of pneumonia, based on data from a nationwide cohort study of more than 100,000 patients.
“Recently, middle ear diseases, including COM, have been recognized as respiratory tract diseases beyond the pathophysiological concepts of ventilation dysfunction, with recurrent infection that occurs from anatomically adjacent structures such as the middle ear, mastoid cavity, and eustachian tube,” but the potential link between pneumonia and chronic otitis media and adults in particular has not been examined, wrote Sung Kyun Kim, MD, of Hallym University, Dongtan, South Korea, and colleagues.
In a study recently published in the International Journal of Infectious Diseases, the researchers identified 23,436 adults with COM and 93,744 controls aged 40 years and older from a Korean health insurance database between 2002 and 2015.
The overall incidence of pneumonia in the study population was significantly higher in the COM group compared with controls (9.3% vs. 7.2%, P <.001). The odds ratios of pneumonia were significantly higher in the COM group compared with controls, and a history of pneumonia increased the odds of COM regardless of sex and across all ages.
Pneumonia was defined as when a patient had a diagnosis of pneumonia based on ICD-10 codes and underwent a chest x-ray or chest CT scan. Chronic otitis media was defined as when a patient had a diagnosis based on ICD-10 codes at least two times with one of the following conditions: chronic serous otitis media, chronic mucoid otitis media, other chronic nonsuppurative otitis media, unspecified nonsuppurative otitis media, chronic tubotympanic suppurative otitis media, chronic atticoantral suppurative otitis media, other chronic suppurative otitis media, or unspecified suppurative otitis media.
Age groups were divided into 5-year intervals, and patients were classified into income groups and rural vs. urban residence.
In a further sensitivity analysis, individuals who were diagnosed with pneumonia five or more times before the index date had a significantly higher odds ratio for COM compared with those with less than five diagnoses of pneumonia (adjusted odds ratio, 1.34; P < .001).
Microbiome dysbiosis may explain part of the connection between pneumonia and COM, the researchers wrote in their discussion. Pathogens in the lungs can prompt changes in the microbiome dynamics, as might the use of antibiotics, they said. In addition, “Mucus plugging in the airway caused by pneumonia induces hypoxic conditions and leads to the expression of inflammatory markers in the eustachian tube and middle ear mucosa,” they noted.
The study findings were limited by several factors, including the retrospective design and lack of data on microbiological cultures for antibiotic susceptibility, radiologic findings on the severity of pneumonia, results of pulmonary function tests, and hearing thresholds, the researchers noted. Other limitations were the exclusion of the frequency of upper respiratory infections and antibiotic use due to lack of data, they said.
However, the results show an association between pneumonia diagnoses and increased incidence of COM, which suggests a novel perspective that “infection of the lower respiratory tract may affect the function of the eustachian tube and the middle ear to later cause COM,” they concluded.
The study received no outside funding. The researchers have disclosed no relevant financial relationships.

Tebipenem pivoxil hydrobromide offers oral option for complex UTIs
“No new oral antibiotic alternative has emerged to treat these conditions in more than 25 years,” corresponding author Angela K. Talley, MD, said in an interview. The new research was published in the New England Journal of Medicine.
Patients with complicated urinary tract infection (cUTI), including acute pyelonephritis (AP), are often hospitalized and treated with intravenous therapy because of the lack of oral options, especially in cases of antibiotic-resistant pathogens, explained Dr. Talley, of Spero Therapeutics.
In their new phase 3, double-blind randomized trial, the researchers evaluated the safety and effectiveness of oral TBP-PI-HBr, compared with intravenous ertapenem in hospitalized patients with cUTIs or AP. Oral tebipenem is an investigational carbapenem with demonstrated activity against uropathogenic Enterobacterales, and it has shown effectiveness in animal models, the researchers noted in their paper.
Methods and results
The researchers randomized 1,372 adult patients. The microbiologic intent-to-treat population included 449 patients who received TBP-PI-HBr (600 mg every 8 hours) and 419 who received ertapenem (1 g every 24 hours) for 7-10 days or up to 14 days for patients with bacteremia.
The primary endpoint was a composite of clinical cure and favorable microbiologic response, assessed at a test-of-cure visit on day 19. Clinical cure was defined as “complete resolution or clinically significant alleviation of baseline signs and symptoms of complicated urinary tract infection or acute pyelonephritis and no new symptoms, such that no further antimicrobial therapy was warranted,” the researchers wrote. Microbiologic response was defined as a reduction to less than 103 CFU per milliliter in uropathogen levels from baseline at day 19.
Overall, the clinical response occurred in 58.8% of patients who received TBP-PI-HBr and 61.6% of those who received ertapenem at the test-of-cure visit.
Clinical cure rates were similar in the TBP-PI-HBr and ertapenem groups (93.1% vs. 93.6%) at the test-of-cure visit.
Both treatment groups showed similar responses to Enterobacterales pathogens at the test-of-cure visit (62.7% for TBP-PI-HBr and 65.2% for ertapenem).
Among patients with bacteremia at baseline, overall response rates were 72.3% and 66.0% for TBP-PI-HBr and ertapenem, respectively, at the test-of-cure visit, and 93.6% and 96.2%, respectively, at the end-of-treatment visit on or around day 25.
The overall incidence of adverse events was approximately 26% in both treatment groups. Most adverse events were mild or moderate in severity and did not limit treatment, the researchers wrote.
The mean age of the patients was 58.1 years; 46.1% were aged 65 and older, and 11.5% had bacteremia at baseline.
The study findings were limited by several factors, including the mandated 7- to 10-day course of antibiotics, which may not reflect the standard of care in other settings in the United States. The study’s trial sites were located in the United States, South Africa, and Europe. The study population was primarily White and from Central and Eastern Europe. Other limitations included the randomization of patients before confirming the baseline pathogen, although this was done to limit potential confounding from previous antibiotics, the researchers noted.
Safety and efficacy support application for approval
“To our knowledge, this is the first head-to-head evaluation of an IV vs. an oral drug for the treatment of cUTI and acute pyelonephritis,” Dr. Talley said in an interview.
“The findings demonstrate that almost all patients in the study achieved complete resolution of the signs and symptoms of their infection,” she said.
TBP-PI-HBr has not been approved by the Food and Drug Administration, but a new drug application that included data from the current study was submitted to the FDA and is currently under review, Dr. Talley noted.
As for additional research, the current study was conducted in hospitalized patients, and the use of TBP-PI-HBr in the outpatient setting has not yet been evaluated, she said.
Approval and use of oral carbapenem will change practice
The current study is very important because it provides a viable and effective alternative form of antibiotic delivery for the patients with complicated UTI, Noel N. Deep, MD, emphasized in an interview.
“Currently these patients have to be treated with IV carbapenem antibiotics either in a hospital or through a home health nurse,” Dr. Deep, a general internist in group practice in Antigo, Wisc., explained.
Current IV strategies also carry the inherent risk associated with the insertion of an IV catheter that is left in place for several days or replaced periodically. “The oral antibiotic eliminates these risks and higher health care costs and provides a safer and equally efficacious option,” Dr. Deep said.
In the current study, “I was definitely surprised at the effectiveness of the oral carbapenem,” Dr. Deep said. “I am absolutely delighted with this new treatment option that physicians can now add to their armamentarium [assuming FDA approval] as we provide care to our patients,” he said.
If approved, TBP-PI-HBr will definitely change the treatment spectrum for the multidrug-resistant bacterial UTIs, said Dr. Deep. “Carbapenems have continued to be effective and low antibiotic resistance to carbapenems has been recorded.”
As for additional research, “I would like to see studies done in other ethnicities and different countries to ascertain the effectiveness of this antibiotic in those populations and against other bacterial strains with potentially different resistance mechanisms,” Dr. Deep said.
The study was supported by Spero Therapeutics and the Department of Health and Human Services. Lead author Paul B. Eckburg, MD, of Stanford (Calif.) University, and Dr. Talley are employees of Spero Therapeutics. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News.

Postmenopausal women may benefit from vaginal estradiol for treatment of symptoms
Vaginal estradiol tablets promoted significant changes in the vaginal microbiota in postmenopausal women compared with vaginal moisturizer or placebo, but reduction in bothersome symptoms were similar, based on data from 144 individuals.
“In the Menopause Strategies–Finding Lasting Answers and Health (MsFLASH) trial network’s Vaginal Health Trial of treatment for moderate to severe vaginal symptoms of menopause, there were no significant differences in reduction of vaginal symptoms among women using the estradiol vaginal tablet or vaginal moisturizer compared to women using the placebo regimen; all three groups had a reduction in vaginal symptoms,” lead author Sujatha Srinivasan, PhD, of the Fred Hutchinson Cancer Center, Seattle, said in an interview.
“However, the impact of these treatments on the vaginal microenvironment are poorly understood,” she said.
In a study published in JAMA Network Open, Dr. Srinivasan and colleagues conducted a secondary analysis to examine the effects of estradiol or a low-pH vaginal moisturizer on the vaginal microbiota, metabolome, and pH after 12 weeks of treatment vs. a low-pH placebo.
“Changes, or lack thereof, in the vaginal microenvironment might have implications beyond symptoms, and might be linked to risk for cervical cancer, genital infections, or other outcomes, though our study did not evaluate those associations,” Dr. Srinivasan said in an interview. Dr. Srinivasan’s comments were corroborated by coauthor Caroline M. Mitchell, MD, of Massachusetts General Hospital, Boston.
The study population included postmenopausal women with moderate to severe genitourinary symptoms who were enrolled in a randomized, controlled trial between April 2016 and February 2017. The average age of the women was 61 years, and 90% were White. The women were randomized to 10 mcg vaginal estradiol plus placebo gel, placebo tablet plus vaginal moisturizer, or a dual placebo.
The primary outcome in the original study was a change in the reported most bothersome symptoms (MBS) selected by the participants at the time of study enrollment; these included pain with penetration, vaginal dryness, and vulvovaginal irritation, itching, and pain. The main outcomes in the secondary analysis were changes in the diversity and composition of the vaginal microbiota, changes in the metabolome, and pH. Microbiota diversity was calculated via the Shannon Diversity Index (SDI).
After 12 weeks, the bacterial microbiota were dominated by Lactobacillus and Bifidobacterium in 80% of the estradiol group, 36% of the moisturizer group, and 26% of the placebo group (P < .001).
In addition, diversity analysis showed significant changes in bacterial composition in women in the estradiol group compared with the placebo group, but no significant differences between the moisturizer and placebo groups.
The composition of vaginal fluid small molecule metabolites changed significantly in 90 of 171 metabolites measured in the estradiol group from baseline to 12 weeks. Changes in the moisturizer and placebo groups were not significant.
Vaginal pH among women in the estradiol group was significantly lower than placebo at 12 weeks, with a median of 5 vs. 6 (P = .005). No significant difference in pH occurred for women in the moisturizer group. “However, pH significantly decreased over 12 weeks within each treatment group, reflecting the low-pH formulations of both the moisturizer and the placebo,” the researchers wrote.
Overall, women with high-diversity bacterial communities at baseline showed a greater median change in pH compared with women with low-diversity communities (median change of −1 vs. −0.3, P = .007).
Improvement in MBS symptoms by at least 2 points occurred in 53% of the estradiol group, 44% of the moisturizer group, and 49% of the placebo group. The similarity in severe symptom improvement among the groups confirms the lack of a causal association between microbiota and postmenopausal vaginal symptom severity, the researchers wrote.
“This study demonstrated that a decrease in vaginal pH alone was insufficient to change the vaginal microbiota,” Dr. Srinivasan said. “While the changes with estrogen were somewhat expected, the observation that low-pH vaginal products don’t change the vaginal microbiota is contrary to some expectations, and suggests that “low-pH” products may not be as helpful as their marketing claims,” she added. “A vaginal microbiota with an abundance of lactobacilli, a vaginal microenvironment with high concentrations of lactate, and a low vaginal pH is associated with health in premenopausal women. We also know that such a microenvironment is typically associated with low inflammation,” said Dr. Srinivasan. “At this time, we don’t have specific information as to how this is beneficial to postmenopausal women,” she noted. However, “If we extrapolate from the data on premenopausal women, the data from this secondary analysis suggests that vaginal estradiol may have positive impacts on the vaginal microenvironment regardless of impact on symptoms,” she said.
“Future areas of investigation should focus on understanding potential benefits of a Lactobacillus-dominant microbiota in postmenopausal women,” Dr. Srinivasan said.
The study findings were limited by several factors including the relatively small number of participants, and collection of data samples at only three time periods, as well as the lack of data on whether the observed changes are durable over longer treatment times, the researchers noted.
“The need to increase participant diversity in studies of postmenopausal women is highlighted by our finding that the 6 Black women in our analysis were all categorized in the low-diversity subgroup; data from premenopausal women suggest that Black women have diverse bacterial communities,” they added.
However, the results suggest that “a significant decrease in pH over the course of a trial may not reflect the same underlying biological processes among different interventions, and thus, lowering pH should not be a primary goal,” they concluded.
Estradiol may have limited clinical impact
“For postmenopausal women with dyspareunia, vaginal dryness, and/or burning/itching/irritation, the question of appropriate treatment is common,” Constance Bohon, MD, a gynecologist in private practice in Washington, said in an interview. “It is helpful to have a study that focuses on the benefit of a moisturizer as compared with vaginal estrogen for these women,” she said.
Dr. Bohon said she was not surprised with the benefits of the moisturizer for dyspareunia and vaginal dryness. “What did surprise me was that the complaint of vaginal itch, burn, or irritation was not significantly improved in the vaginal estrogen group compared with the moisturizer group. I assumed that estrogen would have been more beneficial in this group because these symptoms are more likely to be caused by a vaginal infection that would not be improved with moisturizer alone,” she said. “I expected that the change in the vaginal flora to increase Lactobacillus would have had a greater impact on an infection than the moisturizer, which did not significantly change the flora.”
For clinicians, the take-home message is that, for these patients, use of a moisturizer may be sufficient, Dr. Bohon said.
“Additional research should be done to assess each issue,” she noted. “For example, in the women who have pain with sex, what is the frequency of intercourse?” she asked. Other research should address the questions of whether women who have intercourse at least once a week have less dyspareunia than those who have less frequent sex, and whether a lubricant decreases dyspareunia as well as a moisturizer or vaginal estrogen, she added.

Vaginal estradiol tablets promoted significant changes in the vaginal microbiota in postmenopausal women compared with vaginal moisturizer or placebo, but reduction in bothersome symptoms were similar, based on data from 144 individuals.
“In the Menopause Strategies–Finding Lasting Answers and Health (MsFLASH) trial network’s Vaginal Health Trial of treatment for moderate to severe vaginal symptoms of menopause, there were no significant differences in reduction of vaginal symptoms among women using the estradiol vaginal tablet or vaginal moisturizer compared to women using the placebo regimen; all three groups had a reduction in vaginal symptoms,” lead author Sujatha Srinivasan, PhD, of the Fred Hutchinson Cancer Center, Seattle, said in an interview.
“However, the impact of these treatments on the vaginal microenvironment are poorly understood,” she said.
In a study published in JAMA Network Open, Dr. Srinivasan and colleagues conducted a secondary analysis to examine the effects of estradiol or a low-pH vaginal moisturizer on the vaginal microbiota, metabolome, and pH after 12 weeks of treatment vs. a low-pH placebo.
“Changes, or lack thereof, in the vaginal microenvironment might have implications beyond symptoms, and might be linked to risk for cervical cancer, genital infections, or other outcomes, though our study did not evaluate those associations,” Dr. Srinivasan said in an interview. Dr. Srinivasan’s comments were corroborated by coauthor Caroline M. Mitchell, MD, of Massachusetts General Hospital, Boston.
The study population included postmenopausal women with moderate to severe genitourinary symptoms who were enrolled in a randomized, controlled trial between April 2016 and February 2017. The average age of the women was 61 years, and 90% were White. The women were randomized to 10 mcg vaginal estradiol plus placebo gel, placebo tablet plus vaginal moisturizer, or a dual placebo.
The primary outcome in the original study was a change in the reported most bothersome symptoms (MBS) selected by the participants at the time of study enrollment; these included pain with penetration, vaginal dryness, and vulvovaginal irritation, itching, and pain. The main outcomes in the secondary analysis were changes in the diversity and composition of the vaginal microbiota, changes in the metabolome, and pH. Microbiota diversity was calculated via the Shannon Diversity Index (SDI).
After 12 weeks, the bacterial microbiota were dominated by Lactobacillus and Bifidobacterium in 80% of the estradiol group, 36% of the moisturizer group, and 26% of the placebo group (P < .001).
In addition, diversity analysis showed significant changes in bacterial composition in women in the estradiol group compared with the placebo group, but no significant differences between the moisturizer and placebo groups.
The composition of vaginal fluid small molecule metabolites changed significantly in 90 of 171 metabolites measured in the estradiol group from baseline to 12 weeks. Changes in the moisturizer and placebo groups were not significant.
Vaginal pH among women in the estradiol group was significantly lower than placebo at 12 weeks, with a median of 5 vs. 6 (P = .005). No significant difference in pH occurred for women in the moisturizer group. “However, pH significantly decreased over 12 weeks within each treatment group, reflecting the low-pH formulations of both the moisturizer and the placebo,” the researchers wrote.
Overall, women with high-diversity bacterial communities at baseline showed a greater median change in pH compared with women with low-diversity communities (median change of −1 vs. −0.3, P = .007).
Improvement in MBS symptoms by at least 2 points occurred in 53% of the estradiol group, 44% of the moisturizer group, and 49% of the placebo group. The similarity in severe symptom improvement among the groups confirms the lack of a causal association between microbiota and postmenopausal vaginal symptom severity, the researchers wrote.
“This study demonstrated that a decrease in vaginal pH alone was insufficient to change the vaginal microbiota,” Dr. Srinivasan said. “While the changes with estrogen were somewhat expected, the observation that low-pH vaginal products don’t change the vaginal microbiota is contrary to some expectations, and suggests that “low-pH” products may not be as helpful as their marketing claims,” she added. “A vaginal microbiota with an abundance of lactobacilli, a vaginal microenvironment with high concentrations of lactate, and a low vaginal pH is associated with health in premenopausal women. We also know that such a microenvironment is typically associated with low inflammation,” said Dr. Srinivasan. “At this time, we don’t have specific information as to how this is beneficial to postmenopausal women,” she noted. However, “If we extrapolate from the data on premenopausal women, the data from this secondary analysis suggests that vaginal estradiol may have positive impacts on the vaginal microenvironment regardless of impact on symptoms,” she said.
“Future areas of investigation should focus on understanding potential benefits of a Lactobacillus-dominant microbiota in postmenopausal women,” Dr. Srinivasan said.
The study findings were limited by several factors including the relatively small number of participants, and collection of data samples at only three time periods, as well as the lack of data on whether the observed changes are durable over longer treatment times, the researchers noted.
“The need to increase participant diversity in studies of postmenopausal women is highlighted by our finding that the 6 Black women in our analysis were all categorized in the low-diversity subgroup; data from premenopausal women suggest that Black women have diverse bacterial communities,” they added.
However, the results suggest that “a significant decrease in pH over the course of a trial may not reflect the same underlying biological processes among different interventions, and thus, lowering pH should not be a primary goal,” they concluded.
Estradiol may have limited clinical impact
“For postmenopausal women with dyspareunia, vaginal dryness, and/or burning/itching/irritation, the question of appropriate treatment is common,” Constance Bohon, MD, a gynecologist in private practice in Washington, said in an interview. “It is helpful to have a study that focuses on the benefit of a moisturizer as compared with vaginal estrogen for these women,” she said.
Dr. Bohon said she was not surprised with the benefits of the moisturizer for dyspareunia and vaginal dryness. “What did surprise me was that the complaint of vaginal itch, burn, or irritation was not significantly improved in the vaginal estrogen group compared with the moisturizer group. I assumed that estrogen would have been more beneficial in this group because these symptoms are more likely to be caused by a vaginal infection that would not be improved with moisturizer alone,” she said. “I expected that the change in the vaginal flora to increase Lactobacillus would have had a greater impact on an infection than the moisturizer, which did not significantly change the flora.”
For clinicians, the take-home message is that, for these patients, use of a moisturizer may be sufficient, Dr. Bohon said.
“Additional research should be done to assess each issue,” she noted. “For example, in the women who have pain with sex, what is the frequency of intercourse?” she asked. Other research should address the questions of whether women who have intercourse at least once a week have less dyspareunia than those who have less frequent sex, and whether a lubricant decreases dyspareunia as well as a moisturizer or vaginal estrogen, she added.

Atypical anxiety offers intervention target in Parkinson’s disease
Anxiety is common in Parkinson’s disease (PD) and has been shown to increase functional disability and decrease quality of life, but atypical presentations of anxiety are underrecognized and often undertreated in PD patients, wrote Nadeeka N. Dissanayaka, PhD, of the University of Queensland, Brisbane, Australia, and colleagues.
In a study published in the American Journal of Geriatric Psychiatry , the researchers conducted a systematic review of 60 studies to better characterize atypical PD-related anxiety. Fourteen studies involved Anxiety Not Otherwise Specified (NOS), 31 included fluctuating anxiety symptoms, and 22 included Fear of Falling (FOF).
Overall, the average prevalence rate for anxiety disorders in the PD population was 31%.
Anxiety NOS, fluctuating anxiety, and FOF accounted for a weighted mean prevalence of 14.9%, 34.19%, and 51.5%, respectively.
The symptomatology of anxiety NOS included psychological distress about the PD diagnosis, insecurity about the future, fear of losing control of motor and bodily functions, and social embarrassment. Clinically, anxiety NOS was associated with a range of factors including minor depression, on-off motor symptoms, muscle cramps, poor quality of life, and gait impairment.
The symptomatology of fluctuating anxiety was assessed in 9 studies of the “on” motor state and 16 studies of both “on” and “off.” Symptoms associated with the off state included panic attacks, feeling anxious or sad, and avoiding situations, as well as palpitations, dizziness, chills, and hot flashes.
Clinically, studies showed that anxiety was more severe in the off-medication state, and symptoms were reduced in the on state. Data from some studies showed that fluctuating anxiety was more common in PD patients who were female, and who had a younger age of PD onset and longer disease duration.
The symptomatology of FOF included associations between FOF and difficulty with walking and gait: Using a walker or other device, more frequent freezing in place, hesitation when turning, and slower speed while walking. Clinically, characteristics associated with FOF included older age, needing assistance for activities of daily living, a history of falls, and reduced quality of life.
The results of the review were limited by several factors including the varying assessment techniques, and the lack of data on treatment for atypical anxiety in PD, the researchers noted. “To our knowledge there are no treatment trials focused on Anxiety NOS,” and studies on the treatment of fluctuating anxiety and FOF are preliminary, they said.
However, the results support the need for early identification and classification of PD-related anxiety to improve treatment strategies and long-term outcomes, the researchers concluded. In the absence of evidence-based treatment strategies, “Given the heterogeneity of anxiety presentations in PD, the importance of tailoring interventions to meet the specific needs and unique symptom profiles of each individual cannot be overstated,” and routine screening of PD patients for anxiety every 6-12 months is recommended, they emphasized.

Pneumococcal pneumonia outcomes worse than those of Legionnaires disease
Outcomes for patients with bacteremic Streptococcus pneumoniae were significantly worse than those for patients with Legionnaires disease (LD), based on data from 106 individuals.
Reported cases of LD in the United States have increased in recent decades, but they are likely under-reported, wrote Sima Salahie, MD, of Wayne State University School of Medicine, Detroit, and Central Michigan University College of Medicine, Grosse Pointe Woods, and colleagues.
Clinical presentations may be similar for both conditions, but different antimicrobial therapies are needed; therefore, identifying distinguishing factors can promote better management of hospitalized patients, they reported.
In a retrospective case companion study published in the American Journal of the Medical Sciences, the researchers reviewed data from 51 adults with LD and 55 with bacteremic S. pneumoniae pneumonia (SP) who were hospitalized at a single center between 2013 and 2018. Diagnoses were confirmed by laboratory and radiology results. In addition, data were collected on clinical features including body mass index, systolic and diastolic blood pressure, pulse, respiratory rate, and temperature.
Overall, patients with SP were significantly more likely than those with LD to require mechanical ventilation (P = .04), intensive care unit stay (P = .004), and to die (P = .002). Patients with SP also had higher rates of septic shock compared to LD patients, although this difference fell short of statistical significance (49.1% vs. 30.4%; P = .06).
In a multivariate analysis, male sex, diarrhea, higher body mass index, hyponatremia, and lower Charleston Weighted Index of Comorbidity (CWIC) score were significant independent predictors of LD, with odds ratios of 21.6, 4.5, 1.13, 5.6, and 0.61, respectively.
The incidence of LD peaked in summer, while the incidence of SP peaked in the winter, the researchers noted. “Seasonality is a variable that has not always been included in previous scoring systems but should be considered in future modeling,” they said.
“Noteworthy is that LD represented almost as many cases as documented bacteremic pneumococcal pneumonia,” the researchers wrote in their discussion. “This occurred at a time when there was no outbreak of L. pneumophila in our community, and as these were all community acquired, there was no evidence of a nosocomial outbreak in our institution,” they said.
The study findings were limited by several factors, including the possible underestimation of SP because of the requirement for positive blood cultures and the lack of other methods of diagnosing SP, the researchers noted.
“However, the data suggest variables to distinguish LD from SP,” they said. “Establishing reliable clinical and laboratory parameters embedded in a simple diagnostic score that can accurately identify patients with LD may be helpful in aiding physicians’ early diagnosis in distinguishing LD from SP but will need to be defined.”
The study received no outside funding. The researchers disclosed no financial conflicts.
