Excess mortality among people with endogenous Cushing’s syndrome (CS) has declined in the past 20 years yet remains three times higher than in the general population, new research finds.

Among more than 90,000 individuals with endogenous CS, the overall proportion of mortality – defined as the ratio of the number of deaths from CS divided by the total number of CS patients – was 0.05, and the standardized mortality rate was an “unacceptable” three times that of the general population, Padiporn Limumpornpetch, MD, reported on March 20 at ENDO 2021: The Endocrine Society Annual Meeting.

Excess deaths were higher among those with adrenal CS, compared with those with Cushing’s disease. The most common causes of death among those with CS were cardiovascular diseases, cerebrovascular accident, infection, and malignancy, noted Dr. Limumpornpetch, of Songkla University, Hat Yai, Thailand, who is also a PhD student at the University of Leeds, United Kingdom.

“While mortality has improved since 2000, it is still significantly compromised compared to the background population ... The causes of death highlight the need for aggressive management of cardiovascular risk, prevention of thromboembolism, infection control, and a normalized cortisol level,” she said.

Asked to comment, Maria Fleseriu, MD, told this news organization that the new data show “we are making improvements in the care of patients with CS and thus outcomes, but we are not there yet ... This meta-analysis highlights the whole spectrum of acute and life-threatening complications in CS and their high prevalence, even before disease diagnosis and after successful surgery.”

She noted that although she wasn’t surprised by the overall results, “the improvement over time was indeed lower than I expected. However, interestingly here, the risk of mortality in adrenal Cushing’s was unexpectedly high despite patients with adrenal cancer being excluded.”

Dr. Fleseriu, who is director of the Pituitary Center at Oregon Health and Science University, Portland, advised, “Management of hyperglycemia and diabetes, hypertension, hypokalemia, hyperlipidemia, and other cardiovascular risk factors is generally undertaken in accordance with standard of clinical care.”

“But we should focus more on optimizing more aggressively this care in addition to the specific Cushing’s treatment,” she stressed.

In addition, she noted, “Medical therapy for CS may be needed even prior to surgery in severe and/or prolonged hypercortisolism to decrease complications ... We definitely need a multidisciplinary approach to address complications and etiologic treatment as well as the reduced long-term quality of life in patients with CS.”

Largest study in scale and scope of Cushing’s syndrome mortality

Endogenous Cushing’s syndrome occurs when the body overproduces cortisol. The most common cause of the latter is a tumor of the pituitary gland (Cushing’s disease), but another cause is a usually benign tumor of the adrenal glands (adrenal Cushing’s syndrome). Surgery is the mainstay of initial treatment of Cushing’s syndrome. If an operation to remove the tumor fails to cause remission, medications are available.

Prior to this new meta-analysis, there had been limited data on mortality among patients with endogenous CS. Research has mostly been limited to single-cohort studies. A previous systematic review/meta-analysis comprised only seven articles with 780 patients. All the studies were conducted prior to 2012, and most were limited to Cushing’s disease.

“In 2021, we lacked a detailed understanding of patient outcomes and mortality because of the rarity of Cushing’s syndrome,” Dr. Limumpornpetch noted.

The current meta-analysis included 91 articles that reported mortality among patients with endogenous CS. There was a total of 19,181 patients from 92 study cohorts, including 49 studies on CD (n = 14,971), 24 studies on adrenal CS (n = 2304), and 19 studies that included both (n = 1906).

Among 21 studies that reported standardized mortality rate (SMR) data, including 13 CD studies (n = 2160) and seven on adrenal CS (n = 1531), the overall increase in mortality compared to the background population was a significant 3.00 (range, 1.15-7.84).

This SMR was higher among patients with adrenal Cushing’s syndrome (3.3) versus Cushing’s disease (2.8) (P = .003) and among patients who had active disease (5.7) versus those whose disease was in remission (2.3) (P < .001).

The SMR was also worse among patients with Cushing’s disease with larger tumors (macroadenomas), at 7.4, than among patients with very small tumors (microadenomas), at 1.9 (P = .004).

The proportion of death was 0.05 for CS overall, with 0.04 for CD and 0.02 for adrenal adenomas.

Compared to studies published prior to the year 2000, more recent studies seem to reflect advances in treatment and care. The overall proportion of death for all CS cohorts dropped from 0.10 to 0.03 (P < .001); for all CD cohorts, it dropped from 0.14 to 0.03; and for adrenal CS cohorts, it dropped from 0.09 to 0.03 (P = .04).

Causes of death were cardiovascular diseases (29.5% of cases), cerebrovascular accident (11.5%), infection (10.5%), and malignancy (10.1%). Less common causes of death were gastrointestinal bleeding and acute pancreatitis (3.7%), active CS (3.5%), adrenal insufficiency (2.5%), suicide (2.5%), and surgery (1.6%).

Overall, in the CS groups, the proportion of deaths within 30 days of surgery dropped from 0.04 prior to 2000 to 0.01 since (P = .07). For CD, the proportion dropped from 0.02 to 0.01 (P = .25).

Preventing perioperative mortality: Consider thromboprophylaxis

Dr. Fleseriu told this news organization that she believes hypercoagulability is “the least recognized complication with a big role in mortality.” Because most of the perioperative mortality is due to venous thromboembolism and infections, “thromboprophylaxis should be considered for CS patients with severe hypercortisolism and/or postoperatively, based on individual risk factors of thromboembolism and bleeding.”

Recently, Dr. Fleseriu’s group showed in a single retrospective study that the risk for arterial and venous thromboembolic events among patients with CS was approximately 20%. Many patients experienced more than one event. Risk was higher 30 to 60 days postoperatively.

The odds ratio of venous thromoboembolism among patients with CS was 18 times higher than in the normal population.

“Due to the additional thrombotic risk of surgery or any invasive procedure, anticoagulation prophylaxis should be at least considered in all patients with Cushing’s syndrome and balanced with individual bleeding risk,” Dr. Fleseriu advised.

A recent Pituitary Society workshop discussed the management of complications of CS at length; proceedings will be published soon, she noted.

Dr. Limumpornpetch commented, “We look forward to the day when our interdisciplinary approach to managing these challenging patients can deliver outcomes similar to the background population.”

Dr. Limumpornpetch has disclosed no relevant financial relationships. Dr. Fleseriu has been a scientific consultant to Recordati, Sparrow, and Strongbridge and has received grants (inst) from Novartis and Strongbridge.

A study using data from Veterans Health Administration (VHA) electronic medical records shows a significant association between posttraumatic stress disorder (PTSD) among female veterans and an increased risk for incident ischemic heart disease (IHD).

The increased risk for IHD was highest among women younger than 40 with PTSD, and among racial and ethnic minorities.

“These women have been emerging as important targets for cardiovascular prevention, and our study suggests that PTSD may be an important psychosocial risk factor for IHD in these individuals,” wrote the researchers, led by Ramin Ebrahimi, MD, department of medicine, cardiology section, Veterans Affairs Greater Los Angeles Health Care System. “With the number of women veterans growing, it is critical to appreciate the health care needs of this relatively young and diverse patient population.”

The study results also have “important implications for earlier and more aggressive IHD risk assessment, monitoring and management in vulnerable women veterans,” they added. “Indeed, our findings support recent calls for cardiovascular risk screening in younger individuals and for the need to harness a broad range of clinicians who routinely treat younger women to maximize prevention efforts.”

The article was published online in JAMA Cardiology on March 17.
 

Increasing number of VHA users

“As an interventional cardiologist and the director of the cardiac catheterization laboratory, I noticed a significant number of the patients referred to the cath lab carried a diagnosis of posttraumatic stress disorder,” Dr. Ebrahimi said in an interview. “This intrigued me and started my journey into trying to understand how psychiatric disorders in general, and PTSD, may impact/interact with cardiovascular disorders,” he added.

The number of female veterans in the military has been increasing, and they now make up about 10% of the 20 million American veterans; that number is projected to exceed 2.2 million in the next 20 years, the authors wrote. Female veterans are also the fastest growing group of users of the VHA, they added.

IHD is the leading cause of death in women in the United States, despite the advancements in prevention and treatment. Although women are twice as likely to develop PTSD as are men, and it is even more likely in female veterans, much of the research has predominately been on male veterans, the authors wrote.

For this retrospective study, which used data from the VHA Corporate Data Warehouse, the authors examined a cohort of female veterans who were 18 years or older who had used the VHA health care system between Jan. 1, 2000, and Dec. 31, 2017.

Of the 828,997 female veterans, 151,030 had PTSD. Women excluded from the study were those who did not have any clinical encounters after their index visit, participants who had a diagnosis of IHD at or before the index visit, and those with incident IHD within 90 days of the index visit, allowing time between a PTSD diagnosis and IHD.

Propensity score matching on age at index visit, the number of previous visits, and the presence of traditional and female-specific cardiovascular risk factors, as well as mental and physical health conditions, was conducted to identify female veterans ever diagnosed with PTSD, who were matched in a 1:2 ratio to those never diagnosed with PTSD. In all, 132,923 women with PTSD and 265,846 women without PTSD were included, and data were analyzed for the period of Oct. 1, 2018, to Oct. 30, 2020.

IHD was defined as new-onset coronary artery disease, angina, or myocardial infarction–based ICD-9 and ICD-10 diagnostic codes. Age, race, and ethnicity were self-reported.

The analytic sample consisted of relatively young female veterans (mean [SD] age at baseline, 40.1 [12.2] years) of various races (White, 57.6%; Black, 29.8%) and ethnicities, the authors reported.

Of the 9,940 women who experienced incident IHD during follow-up, 5,559 did not have  PTSD (2.1% of the overall population examined) and 4,381 had PTSD (3.3%). PTSD was significantly associated with an increased risk for IHD. Over the median follow-up of 4.9 years, female veterans with PTSD had a 44% higher rate of developing incident IHD compared with the female veterans without PTSD (hazard ratio [HR], 1.44; 95% confidence interval [CI], 1.38-1.50).

In addition, those with PTSD who developed IHD were younger at diagnosis (mean [SD] age, 55.5 [9.7]) than were patients without PTSD (mean [SD] age, 57.8 [10.7]). Effect sizes were largest in the group younger than 40 years (HR, 1.72; 95% CI, 1.55-1.90) and decreased for older participants (HR for those ≥60 years, 1.24; 95% CI, 1.12-1.38)

The authors found a 49% to 66% increase in risk for IHD associated with PTSD in Black women (HR, 1.49; 95% CI, 1.38-1.62) and those identified as non-White and non-Black (HR, 1.66; 95%, 1.33-2.08).

Women of all ethnic groups with PTSD were at higher risk of developing IHD, but this was especially true for Hispanic/Latina women (HR, 1.50; 95% CI 1.22-1.84), they noted.

The authors reported some limitations to their findings. The analytic sample could result in a lower ascertainment of certain conditions, such as psychiatric disorders, they wrote. Substance disorders were low in this study, possibly because of the younger age of female veterans in the sample. Because this study used VHA electronic medical records data, medical care outside of the VHA that was not paid for by the VHA could not be considered.

In addition, although this study used a large sample of female veterans, the findings cannot be generalized to female veterans outside of the VHA system, nonveteran women, or men, the researchers wrote.


 

A call to action

In an accompanying comment, Beth E. Cohen, MD, of the University of California, San Francisco, and the San Francisco Veterans Affairs Health Care System, points out that the physical implications for psychosocial conditions, including depression and PTSD, have been recognized for quite some time. For example, results of the INTERHEART case-control study of 30,000 people showed stress, depression, and stressful life events accounted for one-third the population-attributable risk for myocardial infarction.

As was also noted by Dr. Ebrahimi and colleagues, much of the current research has been on male veterans, yet types of trauma differ among genders; women experience higher rates of military sexual trauma but lower rates of combat trauma, Dr. Cohen wrote. The PTSD symptoms, trajectory, and biological effects can differ for women and men, as can the pathogenesis, presentation, and outcomes of cardiovascular disease (CVD).

These findings, she said, “are an important extension of the prior literature and represent the largest study in female veterans to date. Although methods differ across studies, the magnitude of risk associated with PTSD was consistent with that found in prior studies of male veterans and nonveteran samples.”

The assessment of age-specific risk is also a strength of the study, “and has implications for clinical practice, because PTSD-associated risk was greatest in a younger group in whom CVD may be overlooked.”

Dr. Cohen addressed the limitations outlined by the authors, including ascertainment bias, severity of PTSD symptoms, and their chronicity, but added that “even in the context of these limitations, this study illustrates the importance of PTSD to the health of women veterans and the additional work needed to reduce their CVD risk.”

Clinical questions remain, she added. Screens for PTSD are widely used in the VHA, yet no studies have examined whether screening or early detection decrease CVD risk. In addition, no evidence suggests that screening for or treatment of PTSD improves cardiovascular outcomes.

“Given the challenges of answering these questions in observational studies, it will be important to incorporate measures of CVD risk and outcomes in trials of behavioral and medical therapies for patients with PTSD,” she wrote.

She added that collaborations among multidisciplinary patient care teams will be important. “The findings of this study represent a call to action for this important work to understand the cardiovascular effects of PTSD and improve the health and well-being of women veterans,” Dr. Cohen concluded.

This research was supported by Investigator-Initiated Research Award from the Department of Defense U.S. Army Medical Research and Material Command Congressionally Directed Medical Research Programs (Dr. Ebrahimi) and in part by grants from the VA Informatics and Computing Infrastructure and the Offices of Research and Development at the Northport, Durham, and Greater Los Angeles Veterans Affairs medical centers. Dr. Ebrahimi reported receiving grants from the Department of Defense during the conduct of the study. Disclosures for other authors are available in the paper. Dr. Cohen reports no disclosures.

The analytic sample consisted of relatively young female veterans (mean [SD] age at baseline, 40.1 [12.2] years) of various races (White, 57.6%; Black, 29.8%) and ethnicities, the authors reported.

Of the 9,940 women who experienced incident IHD during follow-up, 5,559 did not have  PTSD (2.1% of the overall population examined) and 4,381 had PTSD (3.3%). PTSD was significantly associated with an increased risk for IHD. Over the median follow-up of 4.9 years, female veterans with PTSD had a 44% higher rate of developing incident IHD compared with the female veterans without PTSD (hazard ratio [HR], 1.44; 95% confidence interval [CI], 1.38-1.50).

In addition, those with PTSD who developed IHD were younger at diagnosis (mean [SD] age, 55.5 [9.7]) than were patients without PTSD (mean [SD] age, 57.8 [10.7]). Effect sizes were largest in the group younger than 40 years (HR, 1.72; 95% CI, 1.55-1.90) and decreased for older participants (HR for those ≥60 years, 1.24; 95% CI, 1.12-1.38)

The authors found a 49% to 66% increase in risk for IHD associated with PTSD in Black women (HR, 1.49; 95% CI, 1.38-1.62) and those identified as non-White and non-Black (HR, 1.66; 95%, 1.33-2.08).

Women of all ethnic groups with PTSD were at higher risk of developing IHD, but this was especially true for Hispanic/Latina women (HR, 1.50; 95% CI 1.22-1.84), they noted.

The authors reported some limitations to their findings. The analytic sample could result in a lower ascertainment of certain conditions, such as psychiatric disorders, they wrote. Substance disorders were low in this study, possibly because of the younger age of female veterans in the sample. Because this study used VHA electronic medical records data, medical care outside of the VHA that was not paid for by the VHA could not be considered.

In addition, although this study used a large sample of female veterans, the findings cannot be generalized to female veterans outside of the VHA system, nonveteran women, or men, the researchers wrote.


 

A call to action

In an accompanying comment, Beth E. Cohen, MD, of the University of California, San Francisco, and the San Francisco Veterans Affairs Health Care System, points out that the physical implications for psychosocial conditions, including depression and PTSD, have been recognized for quite some time. For example, results of the INTERHEART case-control study of 30,000 people showed stress, depression, and stressful life events accounted for one-third the population-attributable risk for myocardial infarction.

As was also noted by Dr. Ebrahimi and colleagues, much of the current research has been on male veterans, yet types of trauma differ among genders; women experience higher rates of military sexual trauma but lower rates of combat trauma, Dr. Cohen wrote. The PTSD symptoms, trajectory, and biological effects can differ for women and men, as can the pathogenesis, presentation, and outcomes of cardiovascular disease (CVD).

These findings, she said, “are an important extension of the prior literature and represent the largest study in female veterans to date. Although methods differ across studies, the magnitude of risk associated with PTSD was consistent with that found in prior studies of male veterans and nonveteran samples.”

The assessment of age-specific risk is also a strength of the study, “and has implications for clinical practice, because PTSD-associated risk was greatest in a younger group in whom CVD may be overlooked.”

Dr. Cohen addressed the limitations outlined by the authors, including ascertainment bias, severity of PTSD symptoms, and their chronicity, but added that “even in the context of these limitations, this study illustrates the importance of PTSD to the health of women veterans and the additional work needed to reduce their CVD risk.”

Clinical questions remain, she added. Screens for PTSD are widely used in the VHA, yet no studies have examined whether screening or early detection decrease CVD risk. In addition, no evidence suggests that screening for or treatment of PTSD improves cardiovascular outcomes.

“Given the challenges of answering these questions in observational studies, it will be important to incorporate measures of CVD risk and outcomes in trials of behavioral and medical therapies for patients with PTSD,” she wrote.

She added that collaborations among multidisciplinary patient care teams will be important. “The findings of this study represent a call to action for this important work to understand the cardiovascular effects of PTSD and improve the health and well-being of women veterans,” Dr. Cohen concluded.

This research was supported by Investigator-Initiated Research Award from the Department of Defense U.S. Army Medical Research and Material Command Congressionally Directed Medical Research Programs (Dr. Ebrahimi) and in part by grants from the VA Informatics and Computing Infrastructure and the Offices of Research and Development at the Northport, Durham, and Greater Los Angeles Veterans Affairs medical centers. Dr. Ebrahimi reported receiving grants from the Department of Defense during the conduct of the study. Disclosures for other authors are available in the paper. Dr. Cohen reports no disclosures.

A study using data from Veterans Health Administration (VHA) electronic medical records shows a significant association between posttraumatic stress disorder (PTSD) among female veterans and an increased risk for incident ischemic heart disease (IHD).

The increased risk for IHD was highest among women younger than 40 with PTSD, and among racial and ethnic minorities.

“These women have been emerging as important targets for cardiovascular prevention, and our study suggests that PTSD may be an important psychosocial risk factor for IHD in these individuals,” wrote the researchers, led by Ramin Ebrahimi, MD, department of medicine, cardiology section, Veterans Affairs Greater Los Angeles Health Care System. “With the number of women veterans growing, it is critical to appreciate the health care needs of this relatively young and diverse patient population.”

The study results also have “important implications for earlier and more aggressive IHD risk assessment, monitoring and management in vulnerable women veterans,” they added. “Indeed, our findings support recent calls for cardiovascular risk screening in younger individuals and for the need to harness a broad range of clinicians who routinely treat younger women to maximize prevention efforts.”

The article was published online in JAMA Cardiology on March 17.
 

Increasing number of VHA users

“As an interventional cardiologist and the director of the cardiac catheterization laboratory, I noticed a significant number of the patients referred to the cath lab carried a diagnosis of posttraumatic stress disorder,” Dr. Ebrahimi said in an interview. “This intrigued me and started my journey into trying to understand how psychiatric disorders in general, and PTSD, may impact/interact with cardiovascular disorders,” he added.

The number of female veterans in the military has been increasing, and they now make up about 10% of the 20 million American veterans; that number is projected to exceed 2.2 million in the next 20 years, the authors wrote. Female veterans are also the fastest growing group of users of the VHA, they added.

IHD is the leading cause of death in women in the United States, despite the advancements in prevention and treatment. Although women are twice as likely to develop PTSD as are men, and it is even more likely in female veterans, much of the research has predominately been on male veterans, the authors wrote.

For this retrospective study, which used data from the VHA Corporate Data Warehouse, the authors examined a cohort of female veterans who were 18 years or older who had used the VHA health care system between Jan. 1, 2000, and Dec. 31, 2017.

Of the 828,997 female veterans, 151,030 had PTSD. Women excluded from the study were those who did not have any clinical encounters after their index visit, participants who had a diagnosis of IHD at or before the index visit, and those with incident IHD within 90 days of the index visit, allowing time between a PTSD diagnosis and IHD.

Propensity score matching on age at index visit, the number of previous visits, and the presence of traditional and female-specific cardiovascular risk factors, as well as mental and physical health conditions, was conducted to identify female veterans ever diagnosed with PTSD, who were matched in a 1:2 ratio to those never diagnosed with PTSD. In all, 132,923 women with PTSD and 265,846 women without PTSD were included, and data were analyzed for the period of Oct. 1, 2018, to Oct. 30, 2020.

Transgender people treated with gender-affirming hormone therapy show distinctive changes in blood pressure that begin soon after treatment initiation and do not subside over years of treatment, according to the largest and longest observational study to date to look at the issue.

“Many physicians may not be aware of the changes to blood pressure in trans patients who start hormone therapy,” senior author Michael S. Irwig, MD, director of transgender medicine at Beth Israel Deaconess Medical Center in Boston, told this news organization.

“The take-away message for physicians is to monitor blood pressure both before and after starting hormone therapy in transgender patients, as over a third of transgender individuals had stage 1 hypertension before starting hormone therapy, and many had their blood pressure increase after starting hormone therapy.”

Mean blood pressure increases in transgender males, decreases in females

In the study, published in Hypertension, Katherine Banks, MD, George Washington University, Washington, and colleagues, followed 470 transgender adult patients for up to 5 years.

The mean systolic blood pressure levels in transgender female patients (male at birth) significantly decreased compared with baseline within a few months of them starting gender-affirming hormone treatment.

Conversely, the systolic blood pressure levels in transgender males (females at birth) who were treated with testosterone increased over the same period.

There were no significant changes in the groups in terms of diastolic blood pressure, consistent with other studies.

“Our study is the first to describe the time course of the blood pressure effects of gender-affirming hormone therapy and to compare the rates of elevated blood pressure and stage 1 and stage 2 hypertension using blood pressure readings from gender-diverse individuals pre- and post–gender-affirming hormone therapy,” the authors note.

Gender-affirming hormone therapy – which has been prescribed to transgender patients for more than 25 years – typically involves a combination of estrogen and an anti-androgen for males transitioning to female, while the therapy for those transitioning to male generally only involves testosterone.

The therapy has previously been linked to various cardiac effects, with evidence showing transgender men have as much as a 5-times greater risk of heart attack versus cisgender women, the authors note.

Although the American Heart Association issued a 2020 Scientific Statement addressing the cardiovascular disease risk, evidence on the effects specifically on blood pressure in transgender patients has been inconsistent.

For the new study, Dr. Banks and colleagues enrolled 247 transgender females and 223 transgender males who were treated between 2007 and 2015 at two medical centers in Washington, D.C. Of the individuals, who had a mean age of 27.8, about 27% were non-White and 16% were Latinx.

They had blood pressure measurements taken at baseline and at follow-up clinical visits for up to 57 months following the initiation of gender-affirming hormone therapy.

Over the follow-up period, the transgender females had decreases in mean systolic blood pressure of 4.0 mm Hg within 2 to 4 months of starting hormone therapy (P < .0001) and mean declines of 6.0 mm Hg were further observed at 11 to 21 months compared with baseline.

In transgender males, the mean systolic blood pressure increased by 2.6 mm Hg at 2 to 4 months (P = .02), and by 2.9 mm Hg at 11 to 21 months after starting therapy.

Furthermore, “although the average increase in systolic blood pressure was 2.6 mm Hg in transgender men within 2 to 4 months, some patients had much higher increases,” Dr. Irwig noted.

As many as 40% of transgender men had stage 1 hypertension after 11 to 21 months of hormone therapy.

The blood pressure changes in transgender males and females were observed across all three racial ethnic groups of Whites, Blacks, and Latinx, and the changes remained consistent throughout the entire follow-up period of approximately 5 years while hormone therapy was continued.

In addition to the changes after therapy initiation, the researchers note that more than one-third of individuals in both groups had stage 1 hypertension even before starting hormone therapy.

The findings are a concern in light of “clear evidence linking hypertension and higher blood pressure with cardiovascular events such as stroke and heart attacks,” Dr. Irwig said.

Protective effects for transgender females?

Transgender females showed as much as a 47% decrease in the prevalence of stage 2 hypertension, from 19% to 10%, within 2 to 4 months of treatment with gender-affirming hormone therapy (P = .001), and the rate declined further to 8% at 11 to 21 months, suggesting a protective effect of the treatment.

“The rate of stage 2 hypertension did drop in transgender feminine individuals, which could be protective and lower their risk for cardiovascular events,” Dr. Irwig said.

“This was not a surprise, as lowering testosterone and the use of spironolactone can lower blood pressure,” he noted.

Exceptions in both groups

Of note, a sizable proportion of patients had blood pressure changes that were in fact the opposite of the patterns seen in the majority of their gender group.

Specifically, while 42% to 53% of the transgender females had systolic blood pressure readings of at least 5 mm Hg lower than their baseline readings, up to 32% had increases of at least 5 mm Hg compared to baseline readings.

Likewise, whereas 41% to 59% of transgender males had increases of at least 5 mm Hg compared with baseline, up to 35% had levels that were at least 5 mm Hg lower than baseline.

“It was a surprise that over a quarter of individuals had changes opposite to the mean changes,” Dr. Irwig said.

The differing blood pressure changes underscore that “more research is needed to determine which formulations of estrogen, testosterone, and antiandrogens are optimal regarding blood pressure and cardiovascular health, especially in older individuals,” the authors note.

Gender-affirming hormone therapy formulations differ

Various formulations for gender-affirming hormone regimens are available, including oral, transdermal, sublingual, and intramuscular preparations.

In the study, 77% to 91% of transgender males were on intramuscular testosterone injections, with the rest on transdermal formulations, and 92% of transgender female patients were started on oral estradiol, with mean doses generally increasing over time.  

The study’s results are consistent with evidence from other studies, with 7 of 8 involving transgender males showing mean increases in systolic blood pressure ranging from 1 to 14 mm Hg.

Previous research supports cardiovascular risk

As reported by this news organization, other emerging research on cardiovascular risks to transgender people include a recent study showing more than 10% of transgender males were found to have hematocrit levels that could put them at risk for blood clots.

And further research on transgender youth also shows concerning elevations in lipids and other cardiovascular risks.

The authors have disclosed no relevant financial relationships.

“Using interventional cardiologists in this way will help address the huge unmet need for stroke thrombectomy that currently exists,” senior author Petr Widimsky, MD, said in an interview.

Although this may be a feasible way forward in Europe, there is strong opposition to such a proposal from U.S. neurointerventionalists.  

The study, published in the April 12 issue of JACC: Cardiovascular Interventions, describes the establishment of a stroke thrombectomy program in University Hospital Kralovske Vinohrady, a large tertiary hospital in Prague, Czech Republic.

The hospital did not have a neurointerventional program until 2012 when a joint program was started involving an experienced team of cardiologists, angiologists, and one interventional radiologist who trained the cardiologists on the thrombectomy procedure.

The current paper reports on the outcomes of the 333 patients with large vessel occlusion stroke treated under this program between October 2012 and December 2019.

The decision to perform catheter-based thrombectomy was made by a neurologist and was based on acute stroke clinical symptoms and CT angiographic findings.

Results show that functional clinical outcomes, assessed via the Modified Rankin Scale (mRS) score at 3 months, did not vary significantly across years 2012 to 2019, with a favorable outcome (mRS 0 to 2) achieved in 47.9% of patients.

Symptomatic intracerebral hemorrhage occurred in 19 patients (5.7%) and embolization in a new vascular territory occurred in 6 patients (1.8%), outcomes similar to those of neuroradiology centers.

The desired clinical results were achieved from the onset of the program, without any signs of a learning curve effect, they reported.

“These findings support the potential role of interventional cardiac cath labs in the treatment of acute stroke in regions where this therapy is not readily available due to the lack of neurointerventionalists,” the authors concluded.

“Our main message is that our results were excellent from the beginning,” Dr. Widimsky said. “When centers prepare properly, they can achieve excellent results from the beginning with cardiologists who are experienced in interventional procedures and who have spent sufficient time learning about the brain.”  

The authors noted that despite thrombectomy being an extremely beneficial treatment for severe stroke, many eligible patients remain untreated, largely because of a lack of neurointerventionalists in many regions worldwide. They estimate that about 15% of all stroke patients are eligible for thrombectomy but only around 2% of stroke patients in Europe actually receive such treatment.

Dr. Widimsky, an interventional cardiologist, first thought of the idea of using cardiologists to perform stroke thrombectomies after a good friend and colleague suffered a severe stroke in 2010.

“This made us realize that our hospital needed to be more active in the stroke field,” he said. “We decided that we needed to start doing stroke interventions.”

But the major problem was the lack of neurointerventionalists.

“There are not enough neurointerventionalists in Europe. Interventional cardiologists can perform thousands of procedures every year whereas a neurointerventionalist will at best perform hundreds a year. It is quicker and simpler to train the cardiologist to do it,” Dr. Widimsky said.  

They hired one neurointerventionalist to lead the program. “He was our tutor, he taught us his skills,” Dr. Widimsky said. “The cath lab is open 24/7, but if we only have one neurointerventionalist we cannot offer a 24/7 service for stroke thrombectomy. But if we merge with cardiology then we can,” he added.

Their hospital is a very busy center for myocardial infarction, percutaneous coronary intervention, and carotid stenting, he noted. “It is not difficult to make the step from that to stroke thrombectomy. Interventional cardiologists are used to performing carotid and coronary artery stenting. Stroke thrombectomy is a similar technique. The thrombectomy procedure is different from coronary angioplasty but it is not more difficult.  Actually, I think coronary angioplasty can be more difficult.”  

Dr. Widimsky explained that cardiologists need to learn about the brain anatomy and physiology and learn the stroke imaging techniques. “I spent 1 month in the U.S. learning stroke interventions working with simulators,” he said. “I think interventional cardiologists can learn what they need to know in about 6 months. I would recommend they should watch about 50 procedures and perform at least 25 under supervision.”

He said this model is the way forward and hopes it will become routine. Thrombectomy is “tremendously effective” in improving outcomes in severe strokes, with a number needed to treat (NNT) of just 2.6 to prevent long-term disability in one patient, he said, while other procedures can have NNTs of 50 or more.  

“But millions of patients with acute severe stroke are not getting this life-changing treatment,” he added. “We must do everything we can to make this service available to as many patients as possible.”

Dr. Widimsky acknowledges that there has been opposition to this idea from the neurointerventionalist professional bodies but this has lessened recently, at least in Europe. And a program that allows interventionalists with experience in extracranial carotid and vertebral endovascular procedures to “fast-track” technical training has now been proposed.

“There is an enormous unmet need for stroke thrombectomy in Europe, with some countries needing to increase the number of procedures done by 10 or 20 times. These include the U.K., Sweden, Italy, Spain, and Portugal. This cannot be done without cardiology,” Dr. Widimsky said.

Opposition in the United States

Dr. Widimsky explained that this proposal may not be so applicable to the United States, where the need for more clinicians capable of performing stroke thrombectomies does not appear to be as critical, possibly because vascular neurosurgeons as well as neuroradiologists are qualified to undertake these procedures.

In an interview, J. Mocco, MD, director of the cerebrovascular center, department of neurological surgery, at Mount Sinai Health System, New York, confirmed that this was the case.

Patients with heart failure get pneumonia at a rate almost three times greater than expected and, once they do get pneumonia, have about a fourfold greater risk of death, investigators for a retrospective analysis of 13,000 patients from two landmark randomized HF trials have found.

Catherine Hackett/MDedge News

The investigators also found that HF patients with preserved ejection fraction (HFpEF) are at the highest risk of developing pneumonia. The findings underscore the importance of patients with HF getting a pneumonia vaccination, they found.

The analysis showed that 6.3% of patients in the PARADIGM-HF trial and 10.6% of those in the PARAGON-HF trial developed pneumonia, reported the study authors, led by John J.V. McMurray, MD, of the British Heart Foundation Cardiovascular Research Center at the University of Glasgow in Scotland (J Am Coll Cardiol. 2021;77:1961-73).

“The main reason for doing this study was the fact that many heart failure patients are not vaccinated, as they should be, against pneumonia – both pneumococcus and influenza vaccination,” Dr. McMurray said in an interview. “We wanted to document the frequency and consequences of pneumonia in patients with heart failure to help highlight this deficiency in care.”

Dr. McMurray said he believes this is the first study to document the incidence of pneumonia and pneumonia-related outcomes according to the two major ejection fraction phenotypes.
 

PARADIGM-HF and PARAGON-HF

The post hoc analysis consisted of 8,399 patients with HF with reduced ejection fraction (HFrEF) in PARADIGM-HF (Eur J Heart Fail. 2013 Sep;15[9]:1062-73) and 4,796 patients with HFpEF in PARAGON-HF (N Engl J Med. 2014 Sep 11;371[11]:993-1004). The analysis focused on the 528 and 510 patients in each study, respectively, who developed pneumonia. Those rates translated to an incidence rate of 29 per 1,000 patient-years (95% confidence interval, 27-31) in PARADIGM-HF and 39 per 1,000 patient-years (95% CI, 36-42) in PARAGON-HF.

After pneumonia, the risk of death in patients increased substantially. In PARADIGM-HF, the adjusted hazard ratio for the risk of death from any cause after pneumonia was 4.34 (95% CI, 3.73-5.05). In PARAGON-HF, it was 3.76 (95% CI, 3.09-4.58). HF patients who contracted pneumonia also tended to have HF longer than their counterparts who didn’t develop pneumonia, but the frequency of previous hospitalization for HF didn’t vary between the pneumonia and no-pneumonia groups.

Patients who developed pneumonia tended to be older (average age of 66.9 years vs. 64.6 years, P < .001) and male (83.9% vs. 77.8%, P < .001). The mean age of patients in PARADIGM-HF was almost a decade younger than those in PARAGON-HF, 64 vs. 73 years.

Pneumonia patients also had worse Kansas City Cardiomyopathy Questionnaire scores (76 vs. 80 on average), but no difference in New York Heart Association functional class. “In general, patients who developed pneumonia had more symptoms and signs and HF than those who did not develop pneumonia,” Dr. McMurray and colleagues wrote.

Pneumonia patients also had higher rates of chronic obstructive pulmonary disease (26% vs. 12%), diabetes (43% vs. 34%), and atrial fibrillation (46% vs. 36%).

Another reason for conducting the study, Dr. McMurray said, “was the prior findings in patients with coronary disease and acute myocardial infarction that the risk associated with an episode of pneumonia [e.g., in subsequent vascular events and deaths] persisted long after the acute event. We wanted to see if this was also the case for heart failure, and indeed it was.”

For example, the adjusted HR for cardiovascular death or hospitalization in the first month following an episode of pneumonia was 9.48 (range of 6.85-13.12, P < .001), leveling off to 1.59 after 3 months or more.
 

Vaccination crucial in HF patients

Dr. McMurray noted that this study emphasizes the importance of pneumonia vaccination for patients with HF. “Given that we have so few treatments to offer patients with HFpEF, this makes the potential value of vaccination in these patients all the greater,” he said.

The COVID-19 pandemic, Dr. McMurray said, is a “good reminder of the dangers of a respiratory infection and the importance of vaccination in these patients. COVID-19 has interesting parallels in being a systemic disease and one with postacute, persisting effects.”

The persistent risk for adverse cardiovascular events 3 months and later after pneumonia is a novel finding of the study, wrote Donna Mancini, MD, and Gregory Gibson, MD, in an invited commentary (J Am Coll Cardiol. 2021;77:1974-6). Both are with the Icahn School of Medicine at Mt. Sinai in New York. The post hoc study also “serves as an important reminder” of pneumonia risk in patients with HF, especially during the pandemic, they wrote.

“Although vaccination alone appears unlikely to be a panacea, it is a readily accessible tool for mitigating disease severity and improving outcomes,” Dr. Mancini and Dr. Gibson wrote. “After all, an ounce of prevention is worth a pound of cure.”

Novartis provided funding for the PARADIGM-HF and PARAGON-HF trials, and Dr. McMurray and coauthors disclosed financial relationships with Novartis. Dr. Mancini and Dr. Gibson have no relevant financial relationships to disclose.

Pneumonia patients also had worse Kansas City Cardiomyopathy Questionnaire scores (76 vs. 80 on average), but no difference in New York Heart Association functional class. “In general, patients who developed pneumonia had more symptoms and signs and HF than those who did not develop pneumonia,” Dr. McMurray and colleagues wrote.

Pneumonia patients also had higher rates of chronic obstructive pulmonary disease (26% vs. 12%), diabetes (43% vs. 34%), and atrial fibrillation (46% vs. 36%).

Another reason for conducting the study, Dr. McMurray said, “was the prior findings in patients with coronary disease and acute myocardial infarction that the risk associated with an episode of pneumonia [e.g., in subsequent vascular events and deaths] persisted long after the acute event. We wanted to see if this was also the case for heart failure, and indeed it was.”

For example, the adjusted HR for cardiovascular death or hospitalization in the first month following an episode of pneumonia was 9.48 (range of 6.85-13.12, P < .001), leveling off to 1.59 after 3 months or more.
 

Vaccination crucial in HF patients

Dr. McMurray noted that this study emphasizes the importance of pneumonia vaccination for patients with HF. “Given that we have so few treatments to offer patients with HFpEF, this makes the potential value of vaccination in these patients all the greater,” he said.

The COVID-19 pandemic, Dr. McMurray said, is a “good reminder of the dangers of a respiratory infection and the importance of vaccination in these patients. COVID-19 has interesting parallels in being a systemic disease and one with postacute, persisting effects.”

The persistent risk for adverse cardiovascular events 3 months and later after pneumonia is a novel finding of the study, wrote Donna Mancini, MD, and Gregory Gibson, MD, in an invited commentary (J Am Coll Cardiol. 2021;77:1974-6). Both are with the Icahn School of Medicine at Mt. Sinai in New York. The post hoc study also “serves as an important reminder” of pneumonia risk in patients with HF, especially during the pandemic, they wrote.

“Although vaccination alone appears unlikely to be a panacea, it is a readily accessible tool for mitigating disease severity and improving outcomes,” Dr. Mancini and Dr. Gibson wrote. “After all, an ounce of prevention is worth a pound of cure.”

Novartis provided funding for the PARADIGM-HF and PARAGON-HF trials, and Dr. McMurray and coauthors disclosed financial relationships with Novartis. Dr. Mancini and Dr. Gibson have no relevant financial relationships to disclose.

Case

An 88-year-old woman with history of osteoporosis, hyperlipidemia, and a remote myocardial infarction presents to the ED with altered mental status and agitation. The patient is admitted to the medicine service for further management. Her current medications include a thiazide and a statin. Psychiatry is consulted and recommends administering intravenous haloperidol. A baseline EKG shows a corrected QT interval (QTc) of 486 milliseconds (ms). How often should subsequent EKGs be ordered?

Overview of issue

A prolonged QT interval can predispose a patient to dangerous arrhythmias such as Torsades de pointes (TdP), which results in sudden cardiac death in about 10% of cases.^1,2 A prolonged QTc interval can be caused by cardiac, renal, or hepatic dysfunction; congenital Long QT Syndrome (LQTS)²; electrolyte abnormalities; or as a result of many drugs, including most antipsychotic medications such as quetiapine, olanzapine, risperidone and haloperidol.

To diminish risk of TdP while taking these medications, it is necessary to monitor the QTc interval. Before commencing a QT-prolonging medication, it is recommended to get a baseline EKG, then perform EKG monitoring after administering the medication.

According to American Heart Association guidelines, a prolonged QT interval is considered more than 460 ms in women or above 450 ms in men.³ If an abnormal rhythm and/or prolonged QTc is detected via EKG monitoring, then the drug dosage can be changed or an alternative therapy selected.⁴ However, there are no current guidelines recommending how often EKG monitoring should be performed after a QT-prolonging antipsychotic medication is administered on an inpatient medicine unit. Without guidelines, there is potential for health care providers to under- or over-order EKG monitoring, possibly putting patients at risk of TdP or wasting hospital resources, respectively.

Overview of the data

There are currently no universally accepted guidelines regarding inpatient EKG monitoring for patients started on QTc prolonging antipsychotic medications. A 2018 review of the literature surrounding assessment and management of patients on QTc prolonging medications was performed to analyze the available data and make recommendations; notably the evidence was limited as none of the studies were randomized controlled trials.

The authors recommend assessing the drug for QTc prolonging potential, and if possible, choosing alternative treatment in patients with baseline prolonged QTc. If the QT prolonging medication is the best or only option, then the next step is assessing the patient’s risk for QTc prolongation based on that person’s current condition and medical history.⁵ They recommend using the QTc prolonging risk point system developed by Tisdale and colleagues, which identified patient risk factors for elevated QTc intervals based on EKG findings in cardiac care units at a large tertiary hospital center.⁶

Based on the patient’s demographics, current condition, and medication list, the score can be used to stratify patients into low-, medium-, and high-risk categories (see Table 1).

Risk factors include age over 68 years, female sex, prior MI, concurrent use of other QTc prolonging medications, and sepsis, all of which have differing ability to cause QTc prolongation and thus are weighted differentially. This scoring system is helpful in identifying high risk patients; however, the review does not include recommendations for management of these patients beyond removing the offending drug or monitoring EKGs more aggressively in higher risk patients once identified.⁶

Low-risk patients can be managed expectantly. If the baseline QTc is < 500 ms, then the provider may administer the medication, but should obtain follow-up EKG monitoring to ensure the QTc does not rise above 500 ms; if it does, a management change is necessitated. For moderate- to high-risk patients with a baseline QTc > 500 ms, they recommend not administering the medication and consulting a cardiologist. The review does not provide a recommendation on how often EKG monitoring should be performed after prescribing an antipsychotic medication in an inpatient setting.⁵

A 2018 review article explored patient risk factors for a prolonged QTc in the setting of prescribing potentially QTc prolonging antipsychotics.⁷ The authors reiterate that QTc prolonging risk factors are important considerations when prescribing antipsychotics that can lead to adverse events, though they note that much of the literature associating antipsychotics with negative outcomes consists of case reports in which patients had independent risk factors for development of TdP, such as preexisting ventricular arrhythmias.

Providers should assess their patients’ risk factors for QTc prolongation and order a baseline EKG to help quantify the cardiac risk associated with prescribing the drug. In patients with many risk factors or complicated medication regimens, a follow-up EKG should be performed to assess the new QTc baseline. If the subsequent QTc is > 500 ms, then an alternative medication should be strongly considered. The majority of patients, however, will not have a clinically significant increase in their QTc, in which case there is no need for a change in medication and monitoring frequency can be deescalated.
 

Application of data to the case

Our 88-year-old patient has multiple risk factors for a prolonged QTc, and according to the Tisdale scoring system is at moderate risk (7-10 points). Her risk of developing TdP increases with the addition of IV haloperidol to her regimen.

Because of her increased risk, it is reasonable to consider alternative management. If she can cooperate with PO medications, then olanzapine could be given, which has a lesser effect on the QTc interval. If unable to take oral medications, she could be given haloperidol intramuscularly, which causes less QTc prolongation than the IV formulation. If an antipsychotic is administered, she should receive EKG monitoring.

Given the lack of evidence on the optimal monitoring strategy, a protocol should be utilized that balances the ability to capture a clinically meaningful increase in the QTc with appropriate stewardship of resources. Our practice is to initially monitor the EKG every 3 days in moderate- to high-risk patients with baseline QTc < 500 ms. If the QTc remains below 500 ms over three EKGs, then treatment may continue with EKG monitoring weekly while the patient is hospitalized. If the QTc rises above 500 ms, then a management change would be indicated (either dose reduction or a change of agents). If antipsychotic medications are continued, we check the EKG daily while the QTc is >500 ms until there are three unchanged EKGS, and then consider deescalating monitoring to every 3 days.

Bottom line

Prior to prescribing, perform a baseline EKG and assess the patient’s risk of QTc prolongation. If the patient is at increased risk, avoid prescribing QTc prolonging medications where alternatives exist. If a QTc prolonging medication is used in a patient with a moderate- to high-risk score, check an EKG every 3 days or daily if the QTc increases to > 500 ms.

Key points

• An increased QTc interval can lead to TdP, ventricular fibrillation and cardiac death.
• The relative risk of each antipsychotic medication should be determined based on available data and the Tisdale scoring system can provide a system to assess a patient’s risk of QTc prolongation.
• Low-risk patients with a baseline QTc <500 ms should receive a baseline EKG and inpatient EKG monitoring weekly while moderate- to high-risk patients should receive EKG monitoring every 3 days.
• A QTc > 500 ms suggests the need for a management change (drug discontinuation, dose reduction, or a switch to another agent). If the antipsychotic is absolutely necessary, perform daily EKG monitoring until there are three unchanged EKGs, and then consider deescalating monitoring to every 3 days.

Key points

• An increased QTc interval can lead to TdP, ventricular fibrillation and cardiac death.
• The relative risk of each antipsychotic medication should be determined based on available data and the Tisdale scoring system can provide a system to assess a patient’s risk of QTc prolongation.
• Low-risk patients with a baseline QTc <500 ms should receive a baseline EKG and inpatient EKG monitoring weekly while moderate- to high-risk patients should receive EKG monitoring every 3 days.
• A QTc > 500 ms suggests the need for a management change (drug discontinuation, dose reduction, or a switch to another agent). If the antipsychotic is absolutely necessary, perform daily EKG monitoring until there are three unchanged EKGs, and then consider deescalating monitoring to every 3 days.

Quiz

A 70-year-old male inpatient on furosemide with last known potassium level of 3.3 is going to be started on olanzapine. His baseline EKG has a QTc of 470 ms.

How often should he receive EKG monitoring?

A. Daily

B. Every 3 days

C. Weekly

D. Monthly

Answer (C): He is a low risk patient (6 points: over 70 yrs, loop diuretic, K+< 3.5, QTc > 450 ms), so he should receive weekly EKG monitoring.

An advisory committee to the Centers for Disease Control and Prevention is addressing the safety of the Johnson & Johnson COVID-19 vaccine on April 14, 2021, after the CDC and Food and Drug Administration recommended that states hold off on using it pending a detailed review of six cases of the same kind of rare but serious event – a blood clot in the vessels that drain blood from the brain combined with a large drop in platelets, which increases the risk for bleeding.

This combination can lead to severe strokes that can lead to brain damage or death. Among the six cases reported, which came to light over the past 3 weeks, one person died, according to the CDC. All six were women and ranged in age from 18 to 48 years.

According to a report from the Vaccine Adverse Event Reporting System (VAERS), which is maintained by the Department of Health & Human Services, the woman who died was 45. She developed a gradually worsening headache about a week after receiving the Johnson & Johnson vaccine.

On March 17, the day she came to the hospital, she was dry heaving. Her headache had suddenly gotten much worse, and the left side of her body was weak, which are signs of a stroke. A CT scan revealed both bleeding in her brain and a clot in her cortical vein. She died the following day.

In addition to VAERS, which accepts reports from anyone, the CDC and FDA are monitoring at least eight other safety systems maintained by hospitals, research centers, long-term care facilities, and insurance companies for signs of trouble with the vaccines. VAERS data is searchable and open to the public. Most of these systems are not publicly available to protect patient privacy. It’s unclear which systems detected the six cases cited by federal regulators.

“These are very serious and potentially fatal problems occurring in a healthy young adult. It’s serious and we need to get to the bottom of it,” said Ed Belongia, MD, director of the Center for Clinical Epidemiology and Population Health at the Marshfield (Wis.) Clinic Research Institute. Dr. Belongia leads a research team that helps the CDC monitor vaccine safety and effectiveness. 

“Safety is always the highest priority, and I think what we’ve seen here in the past 24 hours is our vaccine safety monitoring system is working,” he said.

Others agree. “I think what CDC and FDA have detected is a rare, but likely real adverse event associated with this vaccine,” said Paul Offit, MD, director of vaccine education at Children’s Hospital of Philadelphia.

Although much is still unknown about these events, they follow a similar pattern of blood clots reported with the AstraZeneca vaccine in Europe. That vaccine is now sold under the brand name Vaxzevria. 

This has experts questioning whether all vaccines of this type may cause these rare clots.

“I think it’s likely a class effect,” said Dr. Offit, who was a member of the FDA advisory committee that reviewed clinical trial data on the J&J vaccine before it was authorized for use.
 

Adenovirus vaccines scrutinized

Both the Johnson & Johnson and Vaxzevria vaccines use an adenovirus to ferry genetic instructions for making the coronaviruses spike protein into our cells.

Adenoviruses are common, relatively simple viruses that normally cause mild cold or flu symptoms. The ones used in the vaccine are disabled so they can’t make us sick. They’re more like Trojan horses. 

Once inside our cells, they release the DNA instructions they carry to make the spike protein of the new coronavirus. Those cells then crank out copies of the spike protein, which then get displayed on the outer surface of the cell membrane where they are recognized by the immune system. 

The immune system then makes antibodies and other defenses against the spike so that, when the real coronavirus comes along, our bodies are ready to fight the infection.

There’s no question the vaccine works. In clinical trials, the Johnson & Johnson vaccine was 66% percent effective at preventing against moderate to severe COVID-19 infection, and none of the patients who got COVID-19 after vaccination had to be admitted to the hospital or died.

The idea behind using adenoviruses in vaccines isn’t a new one. In a kind of fight-fire-with-fire approach, the idea is to use a virus, which is good at infecting us, to fight a different kind of virus.

Researchers have been working on the concept for about 10 years, but the COVID-19 vaccines that use this technology are some of the first adenovirus-vector vaccines deployed in humans. 

Only one other adenovirus vaccine, for Ebola, has been approved for use in humans. It was approved in Europe last year. Before the Johnson & Johnson vaccine, no other adenovirus vector has been available for use in humans in the United States.

There are six adenovirus-vector vaccines for COVID-19. In addition to AstraZeneca and Johnson & Johnson, there’s the Russian-developed vaccine Sputnik V, along with CanSino from China, and the Covishield vaccine in India.

Adenovirus vaccines are more stable than the mRNA vaccines. That makes them easier to store and transport. 

But they have a significant downside, too. Because adenoviruses infect humans out in the world, we already make antibodies against them. So there’s always a danger that our immune systems might recognize and react to the vaccine, rendering it ineffective. For that reason, scientists try to carefully select the adenovirus vectors, or carriers, they use.

The two vaccines under investigation for blood clots are slightly different. The Johnson & Johnson vaccine uses the vector AD26, because most of the population lacks preexisting immunity to it. Vaxzevria uses an adenovirus that infects chimpanzees, called ChAdOx1. 

Vaxzevria has been widely used in Europe but has not yet been authorized in the United States.

On April 7, the European Medicines Agency, Europe’s counterpart to the FDA, ruled that unusual blood clots with low blood platelets should be listed as rare side effects on the Vaxzevria vaccine.

The decision came after reviewing 62 cases of cerebral venous sinus thrombosis (CVST) linked to the vaccine and 25 cases of another rare type of clot, called a splanchnic vein thrombosis. Splanchnic veins drain blood from the major organs in the digestive system, including the stomach, liver, and intestines; 18 of those events were fatal.

The reports were culled from reporting in Europe and the United Kingdom, where around 25 million people have received the Vaxzevria vaccine, making these clots exceptionally rare, but serious.

So far, six cases of CVST have been reported in the United States, after more than 7 million doses of the Johnson & Johnson vaccines have been administered.

A key question for U.S. regulators will be the background rate for these types of rare combinations of clots and deplenished platelets. The background rate is the number of events that would be expected to occur naturally in a population of unvaccinated people. On a press call on April 13, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, was asked about the frequency of this dangerous combination. He said the combination of low platelets and clots was so rare that it was hard to pinpoint, but might be somewhere between 2 and 14 cases per million people over the course of a year.

The first Johnson & Johnson doses were given in early March. That means the six cases came to light within the first few weeks of use of the vaccine in the United States, a very short amount of time.

“These were six cases per million people for 2 weeks, which is the same thing as 25 million per year, so it’s clearly above the background rate,” Dr. Offit said.
 

Studies suggest possible mechanism

On April 9, the New England Journal of Medicine published a detailed evaluation of the 11 patients in Germany and Austria who developed the rare clots after their Vaxzevria vaccines.

The study detected rare antibodies to a signaling protein called platelet factor 4, which helps to coordinate clot formation.

These same type of antibodies form in some people given the blood thinning drug heparin. In those reactions, which are also exceptionally rare, the same type of syndrome develops, leading to large, devastating clots that consume circulating platelets.

It’s not yet clear whether people who develop reactions to the vaccines already have some platelet factor 4 antibodies before they are vaccinated, or whether the vaccines somehow spur the body to make these antibodies, which then launch a kind of autoimmune attack.

The researchers on the paper gave the syndrome a name, vaccine-induced thrombotic thrombocytopenia (VITT).

It’s also not clear why more cases seem to be in women than in men. Andrew Eisenberger, MD, an associate professor of hematology and oncology at Columbia University, New York, said the most common causes of cerebral venous sinus thrombosis have to do with conditions that raise estrogen levels, like pregnancy and hormonal contraception.

“Estrogen naturally leads to changes in several clotting proteins in the blood that may predispose to abnormal blood clotting in a few different sites in the body,” he said. “The clotting changes we are encountering with some of COVID-19 vaccines are likely to be synergistic with the effects of estrogen on the blood.”

No matter the cause, the CDC on April 13 alerted doctors to keep a high index of suspicion for VITT in patients who have received the Johnson & Johnson vaccination within the last 2 weeks. In those patients, the usual course of treatment with blood thinning drugs like heparin may be harmful.

Symptoms to watch for include severe headache or backache, new neurologic symptoms, severe abdominal pain, shortness of breath, leg swelling, tiny red spots on the skin, or easy bruising. 
 

Grappling with evidence

The CDC’s Advisory Committee on Immunization Practices will meet today in an emergency session to review the cases and see if any changes are needed to use of the J&J vaccine in the United States.

Last week, for example, the United Kingdom restricted the use of the AstraZeneca vaccine in people aged younger than 30 years, saying the risks and benefits of vaccination are “more finely balanced” for this age group.

With cases of COVID-19 rising again in the United States, and the Johnson & Johnson vaccine currently the most convenient form of protection against the virus, the committee will have to weigh the risks of that infection against the risk of rare clots caused by vaccination.

They will also likely have to rule out whether any of the cases had COVID. At least one study has reported CVST clots in three patients with confirmed COVID infections. In Europe, COVID infection did not seem to play a role in the formation of the clots with low platelets.

Hilda Bastian, PhD, a clinical trials expert who cofounded the Cochrane Collaboration, said it won’t be an easy task. Much will depend on how certain the committee members feel they know about all the events linked to the vaccine.

“That’s the really, really hard issue from my point of view for them right this moment. Have we missed any? Or how many are we likely to have missed?” asked Dr. Bastian, who lives in Australia.

“In a country that size with that fragmented [of] a health care system, how sure can you be that you know them all? That’s going to be a really difficult situation for them to grapple with, the quality of information that they’ve got,” she said.

It’s not yet clear whether people who develop reactions to the vaccines already have some platelet factor 4 antibodies before they are vaccinated, or whether the vaccines somehow spur the body to make these antibodies, which then launch a kind of autoimmune attack.

The researchers on the paper gave the syndrome a name, vaccine-induced thrombotic thrombocytopenia (VITT).

It’s also not clear why more cases seem to be in women than in men. Andrew Eisenberger, MD, an associate professor of hematology and oncology at Columbia University, New York, said the most common causes of cerebral venous sinus thrombosis have to do with conditions that raise estrogen levels, like pregnancy and hormonal contraception.

“Estrogen naturally leads to changes in several clotting proteins in the blood that may predispose to abnormal blood clotting in a few different sites in the body,” he said. “The clotting changes we are encountering with some of COVID-19 vaccines are likely to be synergistic with the effects of estrogen on the blood.”

No matter the cause, the CDC on April 13 alerted doctors to keep a high index of suspicion for VITT in patients who have received the Johnson & Johnson vaccination within the last 2 weeks. In those patients, the usual course of treatment with blood thinning drugs like heparin may be harmful.

Symptoms to watch for include severe headache or backache, new neurologic symptoms, severe abdominal pain, shortness of breath, leg swelling, tiny red spots on the skin, or easy bruising. 
 

Grappling with evidence

The CDC’s Advisory Committee on Immunization Practices will meet today in an emergency session to review the cases and see if any changes are needed to use of the J&J vaccine in the United States.

Last week, for example, the United Kingdom restricted the use of the AstraZeneca vaccine in people aged younger than 30 years, saying the risks and benefits of vaccination are “more finely balanced” for this age group.

With cases of COVID-19 rising again in the United States, and the Johnson & Johnson vaccine currently the most convenient form of protection against the virus, the committee will have to weigh the risks of that infection against the risk of rare clots caused by vaccination.

They will also likely have to rule out whether any of the cases had COVID. At least one study has reported CVST clots in three patients with confirmed COVID infections. In Europe, COVID infection did not seem to play a role in the formation of the clots with low platelets.

Hilda Bastian, PhD, a clinical trials expert who cofounded the Cochrane Collaboration, said it won’t be an easy task. Much will depend on how certain the committee members feel they know about all the events linked to the vaccine.

“That’s the really, really hard issue from my point of view for them right this moment. Have we missed any? Or how many are we likely to have missed?” asked Dr. Bastian, who lives in Australia.

“In a country that size with that fragmented [of] a health care system, how sure can you be that you know them all? That’s going to be a really difficult situation for them to grapple with, the quality of information that they’ve got,” she said.

Early use of tocilizumab (Actemra) does not reduce myocardial infarct size but modestly increases myocardial salvage in patients with acute ST-segment elevation MI (STEMI), results of the ASSAIL-MI trial suggest.

“We’re among the first to show that you can actually affect the reperfusion injury through anti-inflammatory treatment – it’s sort of a new attack point for treatments in STEMI,” lead author Kaspar Broch, MD, PhD, Oslo University Hospital Rikshospitalet, said in an interview. “What we do now is reperfuse as soon as we can and then add drugs in order to prevent new events, but we don’t really attack the reperfusion injury that occurs when you perform PCI [percutaneous coronary intervention], which has been shown to actually account for some 50% of the final injury.”

The phase 2, proof-of-concept study was prompted by the team’s earlier work in non-STEMI patients, in which a single dose of the interleukin-6 receptor antagonist cut C-reactive protein (CRP) levels by more than 50% during hospitalization and reduced troponin T release after PCI.

For ASSAIL-MI, Dr. Broch and colleagues randomly assigned 199 patients presenting with acute STEMI within 6 hours of symptom onset to a single intravenous injection of 280 mg tocilizumab or placebo during PCI. Patients, study personnel, and caretakers were blinded to treatment. Data were available for 195 patients for the primary endpoint of myocardial salvage index.

As reported in the Journal of the American College of Cardiology, tocilizumab was associated with a higher adjusted myocardial salvage index on cardiac MRI 3-7 days after PCI than placebo (69.3% vs. 63.6%; P = .04).

The extent of microvascular obstruction was less with tocilizumab (0% vs. 4%; P = .03), as was the area under the curve of CRP during hospitalization (1.9 vs. 8.6 mg/L per hour; P < .001).

The final infarct size at 6 months was 21% lower in the tocilizumab group but the difference did not reach statistical significance (7.2% vs. 9.1% of left ventricular mass; P = .08).

There were no between-group differences in troponin T area under the curve during hospitalization (1,614 vs. 2,357 ng/L per hour; P = .13), N-terminal of the prohormone brain natriuretic peptide concentrations at 6 months (79 vs. 63 ng/L; P = .25), or baseline-adjusted left ventricular end-diastolic volume at 6 months (157 vs. 160 mL; P = .54).

Subgroup analyses suggested the positive effect of tocilizumab on myocardial salvage index is limited to patients presenting at least 3 hours after symptom onset versus 3 hours or less (P = .034), with a trend for greater benefit among men versus women (P = .053).

Dr. Broch noted that the absolute effect of tocilizumab on myocardial necrosis was smaller than anticipated when the trial was designed, which may explain the lack of significant reduction in infarct size.

“We were aiming for patients with larger infarctions than we actually ended up with, which is partly due to the strict inclusion criteria and the fact that, with modern treatments, patients don’t end up with large myocardial infarctions,” he said. “But if they had been larger, I think that 20% absolute reduction would have meant a lot in terms of clinical events.”

The study also used a very modest dose of tocilizumab, compared with that used for inflammatory diseases, to minimize a potential negative effect on myocardial healing, for instance, myocardial ruptures, Dr. Broch said. “I’m not sure whether you gain anything by giving a larger dose.”

Serious adverse events were similar in the tocilizumab and placebo groups (19 vs. 15; P = .57). There were no myocardial ruptures, and no patient died or developed heart failure. LDL cholesterol, triglycerides, and liver enzymes increased in the tocilizumab group but were similar at 3 and 6 months.

“IL-6 is a central cytokine involved in all stages of plaque growth, progression, and rupture,” Paul Ridker, MD, MPH, of the Brigham and Women’s Hospital in Boston, and a long-standing investigator in inflammation and atherothrombosis, said in an interview. “These preliminary data in STEMI, like the authors’ prior data in non-STEMI, are consistent with the idea that inhibiting IL-6 could have clinical benefit, a concept that will be taken into a major cardiovascular outcomes trial later this year.”

The cardiovascular outcomes trial, known as ZEUS, will test the novel IL-6 inhibitor ziltivekimab among more than 6,000 very-high-risk atherosclerosis patients who have moderate to severe chronic kidney disease and high sensitivity CRP greater than 2 mg/L, he noted.

Moving beyond IL-1b blockade as done in CANTOS to direct downstream inhibition of IL-6 represents a “logical next scientific step” in the development of anti-inflammatory therapies for acute ischemia and chronic atherosclerosis, Dr. Ridker, who led the CANTOS trial, noted in an accompanying editorial.

“Preventive cardiologists, however, need not wait until outcome trials are complete to use this evolving biological knowledge to their patient’s advantage,” he wrote. “As recently confirmed in the pages of the Journal, exercise, smoking cessation, and a healthy diet reduce both C-reactive protein and IL-6, and clearly have lifelong benefits. Our immediate task is thus to incorporate inflammation inhibition through lifestyle management into our daily practice.”

The study was supported by the South-Eastern Norway Regional Health Authority, Central Norway Regional Health Authority, and Roche, which provided the medicinal products and an unrestricted grant. Dr. Broch has disclosed no relevant financial relationships. Dr. Ridker has received investigator-initiated research grant support from Kowa, Novartis, Amarin, Pfizer, and the National Heart, Lung, and Blood Institute; and has served as a consultant to Novartis, Janssen, Agepha, Flame, Civi Biopharma, Inflazome, Corvidia, Novo Nordisk, SOCAR, IQVIA, and AstraZeneca.

The Food and Drug Administration has declared Medtronic’s recall of seven models of defibrillating cardiac rhythm devices, caused by a risk for premature battery depletion, as class I, which implies a potential risk for serious injury or death. A total of 444 complaints, but no deaths, have been reported in association with the 239,171 affected devices, the agency said in a statement on April 12, 2021.

Physicians were notified of the company’s recall in early February. It covered implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy–defibrillator (CRT-D) models Evera, Viva, Brava, Claria, Amplia, Compia, and Visia distributed from Aug. 31, 2012 to May 9, 2018.

The devices could be subject to “an unexpected and rapid decrease in battery life” because of a possible short circuit that could lead to a device-replacement alert “earlier than expected.” Some devices may experience full battery depletion “within as little as 1 day” after such an alert.

“If the user does not respond to the first warning, the device may stop functioning. The likelihood that this issue will occur is constant after approximately 3 years after device use,” the announcement said.

Medtronic recommends device replacement no more than 1 week after such an early warning for patients who are not pacing dependent or who have them for primary prevention, but right away for pacing-dependent patients.

Remote cardiology clinic visits during COVID-19 were used more often by certain traditionally underserved patient groups, but were also associated with less frequent testing and prescribing, new research shows.

“The COVID-19 pandemic has led to an unprecedented shift in ambulatory cardiovascular care from in-person to remote visits,” lead author Neal Yuan, MD, a cardiology fellow at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

Their findings were published online April 5 in JAMA Network Open.

“We wanted to explore whether the transition to remote visits was associated with disparities in how patients accessed care, and also how this transition affected diagnostic test ordering and medication prescribing,” Dr. Yuan said.

The researchers used electronic health records data for all ambulatory cardiology visits at an urban, multisite health system in Los Angeles County during two periods: April 1 to Dec. 31, 2019, the pre-COVID era; and April 1 to Dec. 31, 2020, the COVID era.

The investigators compared patient characteristics and frequencies of medication ordering and cardiology-specific testing across four visit types: pre-COVID in person, used as reference; COVID-era in person; COVID-era video; and COVID-era telephone.

The study looked at 176,781 ambulatory cardiology visits. Of these visits, 87,182 were conducted in person in the pre-COVID period; 74,498 were conducted in person in the COVID era; 4,720 were COVID-era video visits; and 10,381 were COVID-era telephone visits.

In the study cohort, 79,572 patients (45.0%) were female, 127,080 patients (71.9%) were non-Hispanic White, and the mean age was 68.1 years (standard deviation, 17.0).

Patients accessing COVID-era remote visits were more likely to be Asian, Black, or Hispanic, to have private insurance, and to have cardiovascular comorbidities, such as hypertension and heart failure.

Also, patients whose visits were conducted by video were significantly younger than patients whose visits were conducted in person or by telephone (P < .001).

In addition, the study found that clinicians ordered fewer diagnostic tests, such as electrocardiograms and echocardiograms, and were less likely to order any medication, in the pre-COVID era than during the COVID era.

“If you don’t have a patient in front of you, it’s much more difficult to get a physical exam or obtain reliable vital signs,” said Dr. Yuan. Communication can sometimes be difficult, often because of technical issues, like a bad connection. “You might be more reticent to get testing or to prescribe medications if you don’t feel confident knowing what the patient’s vital signs are.”

In addition, he added, “a lot of medications used in the cardiology setting require monitoring patients’ kidney function and electrolytes, and if you can’t do that reliably, you might be more cautious about prescribing those types of medications.”
 

An eye-opening study

Cardiologist Nieca Goldberg, MD, medical director of the New York University Langone womens’ heart program and spokesperson for the American Heart Association, recounted her experience with telemedicine at the height of the pandemic in New York, when everything, including medical outpatient offices, had to close.

“We were experienced with telemedicine because we had started a virtual urgent care program well ahead of the pandemic,” she said. “We started using that to screen people with potential COVID symptoms so that they wouldn’t have to come into the hospital, the medical center, or to the offices and expose people. We learned that it was great to have the telemedicine option from the infectious disease standpoint, and I did visits like that for my own patient population.”

An equally if not more important finding from the study is the fact that telemedicine increased access to care among traditionally underserved demographics, she said.

“This is eye-opening, that you can actually improve access to care by doing telemedicine visits. It was really important to see that telemedicine has added benefit to the way we can see people in the health care system.”

Telemedicine visits had a positive impact at a time when people were isolated at home, Dr. Goldberg said.

“It was a way for them to connect with their doctor and in some ways it was more personal,” she added. “I actually got to meet some of my patients’ family members. It was like making a remote house call.”

Stable cardiology patients can take their blood pressure at home, weigh themselves, and take their own pulse to give an excellent set of vital signs that will indicate how they are doing, said Dr. Goldberg.

“During a remote visit, we can talk to the patient and notice whether or not they are short of breath or coughing, but we can’t listen to their heart or do an EKG or any of the traditional cardiac testing. Still, for someone who is not having symptoms and is able to reliably monitor their blood pressure and weight, a remote visit is sufficient to give you a good sense of how that patient is doing,” she said. “We can talk to them about their medications, any potential side effects, and we can use their blood pressure information to adjust their medications.”

Many patients are becoming more savvy about using tech gadgets and devices to monitor their health.

“Some of my patients were using Apple watches and the Kardia app to address their heart rate. Many had purchased inexpensive pulse oximeters to check their oxygen during the pandemic, and that also reads the pulse,” Dr. Goldberg said.

In-person visits were reserved for symptomatic cardiac patients, she explained.

“Initially during the pandemic, we did mostly telemedicine visits and we organized the office so that each cardiologist would come in 1 day a week to take care of symptomatic cardiac patients. In that way, we were able to socially distance – they provided us with [personal protective equipment]; at NYU there was no problem with that – and nobody waited in the waiting room. To this day, office issues are more efficient and people are not waiting in the waiting room,” she added. “Telemedicine improves access to health care in populations where such access is limited.”

Dr. Yuan’s research is supported by a grant from the National Institutes of Health. Dr. Goldberg reported no relevant financial relationships.

In addition, he added, “a lot of medications used in the cardiology setting require monitoring patients’ kidney function and electrolytes, and if you can’t do that reliably, you might be more cautious about prescribing those types of medications.”
 

An eye-opening study

Cardiologist Nieca Goldberg, MD, medical director of the New York University Langone womens’ heart program and spokesperson for the American Heart Association, recounted her experience with telemedicine at the height of the pandemic in New York, when everything, including medical outpatient offices, had to close.

“We were experienced with telemedicine because we had started a virtual urgent care program well ahead of the pandemic,” she said. “We started using that to screen people with potential COVID symptoms so that they wouldn’t have to come into the hospital, the medical center, or to the offices and expose people. We learned that it was great to have the telemedicine option from the infectious disease standpoint, and I did visits like that for my own patient population.”

An equally if not more important finding from the study is the fact that telemedicine increased access to care among traditionally underserved demographics, she said.

“This is eye-opening, that you can actually improve access to care by doing telemedicine visits. It was really important to see that telemedicine has added benefit to the way we can see people in the health care system.”

Telemedicine visits had a positive impact at a time when people were isolated at home, Dr. Goldberg said.

“It was a way for them to connect with their doctor and in some ways it was more personal,” she added. “I actually got to meet some of my patients’ family members. It was like making a remote house call.”

Stable cardiology patients can take their blood pressure at home, weigh themselves, and take their own pulse to give an excellent set of vital signs that will indicate how they are doing, said Dr. Goldberg.

“During a remote visit, we can talk to the patient and notice whether or not they are short of breath or coughing, but we can’t listen to their heart or do an EKG or any of the traditional cardiac testing. Still, for someone who is not having symptoms and is able to reliably monitor their blood pressure and weight, a remote visit is sufficient to give you a good sense of how that patient is doing,” she said. “We can talk to them about their medications, any potential side effects, and we can use their blood pressure information to adjust their medications.”

Many patients are becoming more savvy about using tech gadgets and devices to monitor their health.

“Some of my patients were using Apple watches and the Kardia app to address their heart rate. Many had purchased inexpensive pulse oximeters to check their oxygen during the pandemic, and that also reads the pulse,” Dr. Goldberg said.

In-person visits were reserved for symptomatic cardiac patients, she explained.

“Initially during the pandemic, we did mostly telemedicine visits and we organized the office so that each cardiologist would come in 1 day a week to take care of symptomatic cardiac patients. In that way, we were able to socially distance – they provided us with [personal protective equipment]; at NYU there was no problem with that – and nobody waited in the waiting room. To this day, office issues are more efficient and people are not waiting in the waiting room,” she added. “Telemedicine improves access to health care in populations where such access is limited.”

Remote cardiology clinic visits during COVID-19 were used more often by certain traditionally underserved patient groups, but were also associated with less frequent testing and prescribing, new research shows.

“The COVID-19 pandemic has led to an unprecedented shift in ambulatory cardiovascular care from in-person to remote visits,” lead author Neal Yuan, MD, a cardiology fellow at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

Their findings were published online April 5 in JAMA Network Open.

“We wanted to explore whether the transition to remote visits was associated with disparities in how patients accessed care, and also how this transition affected diagnostic test ordering and medication prescribing,” Dr. Yuan said.

The researchers used electronic health records data for all ambulatory cardiology visits at an urban, multisite health system in Los Angeles County during two periods: April 1 to Dec. 31, 2019, the pre-COVID era; and April 1 to Dec. 31, 2020, the COVID era.

The investigators compared patient characteristics and frequencies of medication ordering and cardiology-specific testing across four visit types: pre-COVID in person, used as reference; COVID-era in person; COVID-era video; and COVID-era telephone.

The study looked at 176,781 ambulatory cardiology visits. Of these visits, 87,182 were conducted in person in the pre-COVID period; 74,498 were conducted in person in the COVID era; 4,720 were COVID-era video visits; and 10,381 were COVID-era telephone visits.

In the study cohort, 79,572 patients (45.0%) were female, 127,080 patients (71.9%) were non-Hispanic White, and the mean age was 68.1 years (standard deviation, 17.0).

Patients accessing COVID-era remote visits were more likely to be Asian, Black, or Hispanic, to have private insurance, and to have cardiovascular comorbidities, such as hypertension and heart failure.

Also, patients whose visits were conducted by video were significantly younger than patients whose visits were conducted in person or by telephone (P < .001).

In addition, the study found that clinicians ordered fewer diagnostic tests, such as electrocardiograms and echocardiograms, and were less likely to order any medication, in the pre-COVID era than during the COVID era.

“If you don’t have a patient in front of you, it’s much more difficult to get a physical exam or obtain reliable vital signs,” said Dr. Yuan. Communication can sometimes be difficult, often because of technical issues, like a bad connection. “You might be more reticent to get testing or to prescribe medications if you don’t feel confident knowing what the patient’s vital signs are.”
