The company developing tirzepatide, Lilly, announced these results in a series of four press releases issued during December 2020–May 2021. Scientific reports on the outcomes from four of these trials are scheduled during the American Diabetes Association’s Scientific Sessions being held virtually in late June 2021, with results from the fifth on track for a report during the annual meeting of the European Association for the Study of Diabetes in September 2021.

Tirzepatide is a “twincretin” because it combines in a single molecule two different gut-hormone activities. It works as both a glucagonlike peptide–1 receptor agonist (GLP-1 RA) and as an agent that mimics the glucose-dependent insulinotropic polypeptide (GIP).

While diabetologists qualified their comments on these results because of the limited scope and format of the five reports to date, they also expressed enthusiasm over what the press releases said.
 

Results give hope

“It’s quite exciting, but of course we would like to go by the data that’s presented” at upcoming meetings, commented Robert A. Gabbay, MD, PhD, chief science and medical officer of the American Diabetes Association in Arlington, Va. “The idea of GLP-1 and GIP activities working together has been out there for a while, but without any therapeutic options that leverage this,” he said in an interview.

“The preliminary results give us hope that tirzepatide will be a very effective glucose-lowering agent, perhaps the most effective among all options currently available, including insulin,” commented Ildiko Lingvay, MD, a diabetologist and professor at the University of Texas Southwestern Medical Center, Dallas. “Tirzepatide might have the added benefit of clinically meaningful weight loss,” and “the adverse event profile seems to be in line with what we are accustomed to with the GLP-1 RA class. I look forward to seeing the full results. Tirzepatide promises to be a great addition for type 2 diabetes,” Dr. Lingvay said in an interview.
 

A rare head-to-head against semaglutide

The five phase 3, randomized controlled trials described by Lilly in its four press releases all belong to the SURPASS series of studies for this agent. Perhaps the most intriguing of the five were results from SURPASS-2, announced in a release on March 4. This trial randomized 1,879 patients from the United States or any of seven other countries to 40 weeks of open-label treatment with one of three different dosages of tirzepatide administered by injection once weekly, or to the control group that received a weekly 1-mg injection of semaglutide (Ozempic), the highest dosage approved for controlling glycemia in patients with type 2 diabetes at the time the study launched.

In SURPASS-2 all three tested dosages of tirzepatide led to a significantly larger reduction, from baseline in A1c, compared with semaglutide, after 40 weeks, according to the Lilly release. Each of the three tirzepatide dosages also led to significantly greater weight loss from baseline, compared with semaglutide, and significantly greater percentages of patients who achieved an A1c of less than 7%, compared with semaglutide.

As an example, the highest tested tirzepatide dosage of 15 mg weekly led to an average A1c reduction from baseline of 2.46% and an average weight loss from baseline of 12.4 kg; 92% of patients achieved an A1c of less than 7%, and 51% had their A1c fall below 5.7% which indicates completely normalization of glycemic control. By comparison, the patients randomized to treatment with semaglutide had an average 1.86% reduction in their A1c level from baseline and a 6.2-kg average cut in body weight from baseline; 81% achieved an A1c of less than 7%, and 20% reached an A1c of less than 5.7%.
 

There are caveats

While these findings are notable as a rare example of an industry-sponsored head-to-head comparison of two new agents, the study comes with a few important asterisks.

First, it was open label, a curious limitation given that both agents are delivered by the same delivery method and schedule. “I cannot conclude based on this study that tirzepatide is superior because it was open label,” commented Anastassia Amaro, MD, medical director of Penn Metabolic Medicine at the University of Pennsylvania, Philadelphia.

“The gold standard is the double-blind study. An open-label design is a limitation,” agreed Dr. Gabbay.

A second caveat is that the Food and Drug Administration recently approved a higher dosage of semaglutide (2.4 g once/week) for treating overweight or obesity in patients with type 2 diabetes and in those without diabetes but a different weight-related condition such as hypertension of hypercholesterolemia. This means that the tested comparator dosage of 1 mg/week is no longer the maximum that most patients treated with semaglutide for glycemic control can receive.

“The inevitable question” about this comparison study is “what about a higher semaglutide dose,” and how might tirzepatide perform relative to that, said Dr. Gabbay. The recently approved higher dosage of semaglutide “adds an interesting wrinkle.”

Lilly has launched a series of studies testing tirzepatide as a treatment for overweight or obesity in people without diabetes, but the results are not expected until sometime in 2022 or 2023.

And there’s a third caveat: Semaglutide has already shown its value for cardiovascular risk reduction in patients with type 2 diabetes in the SUSTAIN 6 trial with nearly 3,300 randomized patients followed for 2 years and reported in 2016. The cardiovascular outcomes trial for tirzepatide, SURPASS-CVOT with more than 12,000 patients with type 2 diabetes, is underway but its results are not expected until 2024.

Despite these important limitations, a blinded comparison of tirzepatide and higher-dose semaglutide is unlikely, Dr. Amaro predicted. “It’s not worth the expense,” she said in an interview. A more likely scenario will be that, if tirzepatide enters the U.S. market, decisions on whether to treat patients with it or semaglutide will pivot on factors like the cost for treatment to individual patients based on their insurance coverage and tolerability, suggested both Dr. Amaro and Dr. Gabbay. “Physicians will need to develop a sense for tirzepatide: Do patients tolerate it and are they happy using it?” Dr. Amaro said.
 

Tirzepatide versus insulin, or on top of insulin

The other four trials in patients with type 2 diabetes reported by Lilly in releases included SURPASS-1, which randomized 478 patients to treatment with tirzepatide or placebo as monotherapy; SURPASS-3, which randomized 1,444 patients to tirzepatide or insulin degludec (Tresiba) on top of background treatment with metformin; SURPASS-4, which randomized 2,002 patients with high cardiovascular disease risk to treatment with tirzepatide or insulin glargine (Lantus) on top of background treatment with one to three different oral drugs; and SURPASS-5, which randomized 475 patients to treatment with tirzepatide or placebo on top of background treatment with insulin glargine and optional addition of metformin. Altogether, the five trials randomized nearly 6,300 patients.

The studies that compared tirzepatide against two different types of insulin, and the third that tested tirzepatide on top of insulin glargine, are especially notable. “It’s good to see that the combination [of tirzepatide and insulin glargine] works without causing major adverse events,” said Dr. Amaro.

“These are fair and helpful comparisons. I applaud Lilly for doing the right kind of comparisons,” said Dr. Gabbay.

In total, the five studies “provide evidence that tirzepatide will be effective at all stages of type 2 diabetes and can safely be used in combination with other glucose-lowering agents, including insulin,” said Dr. Lingvay. The studies with active comparator agents “allow us to compare tirzepatide’s efficacy against established therapies.”

The SURPASS trials were sponsored by Lilly, which is developing tirzepatide. Dr. Gabbay had no relevant disclosures. Dr. Lingvay has received research funds, consulting and advisory fees, or other support from Lilly as well as from several other companies including Novo Nordisk, which markets semaglutide (Ozempic) and insulin degludec (Tresiba), and Sanofi, which markets insulin glargine (Lantus). Dr. Amaro has received research funding from Lilly and from Fractyl, and has been a consultant to and received research funding from Novo Nordisk.

The Diagnosis: Paraneoplastic Acanthosis Nigricans 

Histopathologic examination demonstrated verrucous epidermal hyperplasia (Figure, A). Fungal organisms were identified with an Alcian blue and periodic acid-Schiff stain (Figure, B). The organisms demonstrated a vertical orientation in relation to the mucosal surface, which was consistent with candidal organisms.  

Given the rapid eruption of these plaques, the distribution on the oral and palmar surfaces (tripe palms), and the minimal improvement with both systemic steroids and antifungal treatment, a diagnosis of paraneoplastic acanthosis nigricans with secondary candidal infection was made. Drug-induced cheilitis was considered; however, improvement with discontinuation of the suspected offending drug would have been expected. Although chronic mucocutaneous candidiasis was possible, more prompt improvement upon initiation of systemic antifungal therapy would have been observed. Oral Crohn disease should be included in the differential, but it was unlikely given the lack of granulomas on pathology and absence of history of gastrointestinal tract symptoms. Melkersson-Rosenthal syndrome also was unlikely given the lack of facial nerve palsy as well as the lack of granulomas on pathology. Furthermore, none of these options would be associated with tripe palms, as seen in our patient.  

Acanthosis nigricans is a localized skin disorder characterized by hyperpigmented velvety plaques arising in flexural and intertriginous regions. Although most cases (80%) are associated with idiopathic or benign conditions, the link between acanthosis nigricans and an underlying malignancy has been well documented.^1-3 Most commonly associated with an underlying intra-abdominal malignancy (often gastric carcinoma), the lesions of paraneoplastic acanthosis nigricans are indistinguishable from their benign counterparts^.1,4 When the condition presents abruptly and extensively in a nonobese patient, prompt workup for malignancy should be initiated. Rapid onset and atypical distribution (ie, palmar, perioral, or mucosal) more commonly is associated with a paraneoplastic etiology.^5,6 

Histopathology for acanthosis nigricans shows hyperkeratosis and epidermal papillomatosis. Horn pseudocyst formation is possible, but usually no hyperpigmentation is observed. The findings typically are indistinguishable from seborrheic keratoses, epidermal nevi, or lesions of confluent and reticulated papillomatosis of Gougerot and Carteaud.² 

The underlying pathogenesis of acanthosis nigricans is poorly understood. In the benign subtype, insulin resistance commonly has been described. In the paraneoplastic subtype, it is proposed that the tumor produces a transforming growth factor that mimics epidermal growth factor and leads to keratinocyte proliferation.^7,8 Paraneoplastic acanthosis nigricans has the potential to arise at any point of tumor development, further contributing to the diagnostic challenge. Treatment of the skin lesions involves management of the underlying malignancy. Unfortunately, many such malignancies often are at an advanced stage, and subsequent prognosis is poor.²

Experts assessed different chemopreventive agents meant to reduce the incidence of colorectal neoplasia and associated mortality based on whether these agents were effective and safe, but they found few fit both criteria, according to a new clinical practice update from the American Gastroenterological Association.

That said, the update does advise that clinicians use low-dose aspirin therapy in patients who are younger than 70 years with at least a 10-year life expectancy, are not at high risk for bleeding, and have at least a 10% cardiovascular disease risk over the next decade.

This best practice advice statement reflects “high-quality trial data” for this patient population and also echoes U.S. Preventive Services Task Force recommendations, wrote Peter S. Liang, MD, MPH, and his associates on behalf of the American Gastroenterological Association. However, they note that low-dose aspirin therapy has shown inconsistent results for older patients and that its chemopreventive benefits always should be weighed against an individual’s bleeding risk.

Published in Clinical Gastroenterology and Hepatology, the clinical practice update also recommends considering low-dose aspirin therapy for patients with a history of colorectal neoplasia, based on data from several trials in which daily doses of 81-325 mg were associated with a significantly lower likelihood of recurrence of earlier-stage adenomas (the findings did not extend to patients with more advanced lesions). Evidence on sessile serrated polyps is sparser, but there is some indication for a benefit in this setting, the experts noted.

Their best-practice advice also covers nonaspirin nonsteroidal anti-inflammatory drugs, metformin, calcium, vitamin D, folic acid, and statins. Among these agents, only metformin receives even a conditional green light. “Because of the results of a large number of observational studies, a small adenoma trial, as well as a favorable safety profile, metformin may be considered for chemoprevention against colorectal neoplasia in individuals with diabetes,” the experts concluded. Support for this best-practice advice includes a meta-analysis of colorectal cancer–specific survival in 17 observational studies, a meta-analysis of colorectal cancer incidence in 14 observational studies, and a randomized, placebo-controlled trial in which 250 mg daily metformin was safe and associated with a 40% lower risk of recurrent adenoma.

For calcium, study findings have been mixed, and a recent large clinical trial found no overall benefit for adenoma prevention. Because high-dose calcium has been linked to kidney toxicity, hypercalcemia, and prostate cancer, its risks likely outweigh any benefits, the experts concluded. Vitamin D (as monotherapy or with calcium) also has shown no overall benefit for preventing adenomas or sessile serrated lesions. A large ongoing, randomized trial will examine colorectal cancer incidence among adults receiving 5 years of oral vitamin D or placebo, but its results will not be available until at least 2025.

Nonsteroidal anti-inflammatory drugs are not recommended to prevent colorectal neoplasia among average-risk individuals. Cyclooxygenase-2 inhibitors pose “substantial cardiovascular risks,” while nonselective NSAIDs are associated with a significantly increased risk for gastrointestinal bleeding. Meta-analyses have shown no benefit of folic acid for preventing colorectal neoplasia, and observational studies on statins have produced only mixed results.

No funding sources were reported. The experts reported having no conflicts of interest.

Tumor necrosis factor inhibitors reduce both spinal and sacroiliac radiographic progression in early axial spondyloarthritis (axSpA), but the effects take time.

According to data from the German Spondyloarthritis Inception Cohort (GESPIC), it could take 2-4 years after the initiation of TNF inhibitor treatment before x-rays will show any sign of a benefit in either the spine or sacroiliac joints (SIJ).

“The association between anti-TNF treatment and the retardation of radiographic spinal progression in spondyloarthritis appears to be time-shifted,” GESPIC study investigator Denis Poddubnyy, MD, said at the annual European Congress of Rheumatology.

Reporting the spinal findings, Dr. Poddubnyy, who is head of the rheumatology department at Campus Benjamin Franklin of the Charité University Hospital in Berlin noted that “at least 4 years of observation is required” to see an effect of TNF inhibitors on new bone formation. “This might be related to the intermediate and long-lasting process of bone repair that follows the resolution of inflammation and precedes the development of new bone,” he suggested.

The effect on the SIJ may precede the spinal damage, so it’s important to look at how anti-inflammatory treatment might affect the SIJ, Dr. Poddubnyy said in an interview. Results from the SIJ analysis, which were presented by Murat Torgutalp, MD, suggested that there might be a 2-year time lag between TNFi treatment and being able to see something on x-rays.

“Everybody in the past focused on the spine, considering that spinal changes are functionally more relevant than changes in the SIJ,” Dr. Poddubnyy observed.

Structural damage in the spine and SIJ in radiographic axSpA probably occur by different processes, he explained. While it’s more to do with new bone formation in the spine, it’s more to do with erosive damage followed by repair in the SIJ. “It is very likely that in the majority of patients we see that those two processes are somehow disconnected in time,” he suggested.

The GESPIC cohort provides a good base from which to examine the effects of TNF inhibitors on radiographic progression in patients with axSpA for several reasons, observed Dr. Poddubnyy. For one it was established in 2000, so “well before the introduction of TNF-alpha inhibitors.” That means that almost all patients would have been put on TNF inhibitors while enrolled in the cohort, he said, “so we could really follow up them prospectively for a few years.” In fact, just nine patients had been treated with TNF inhibitors at baseline.

Spinal findings

Although TNF inhibitors are widely accepted to be effective anti-inflammatory drugs that can relieve patients’ spinal symptoms, there were inconclusive data on whether they can also have an impact on radiographic progression.

To look at the possible immediate or later effect of TNF inhibitors on spinal radiographic progression, the GESPIC investigators looked at sets of radiographs, taken at least 2 years apart over a 10-year period, from 266 patients, 77 of whom who had been treated with a TNF inhibitor for at least 12 months or more. Overall, there were 103 2-year intervals covered by TNF inhibitor treatment of any duration, and 78 intervals in which treatment had lasted for at least 12 months.

“This cohort included patients with quite early disease, including both nonradiographic and radiographic forms,” Dr. Poddubnyy said, adding that some patients had been treated with a TNF inhibitor for up to 10 years.

While there were no significant changes in radiographic progression as measured using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) between patients who had and who had not received at least 12 months’ TNF inhibitor therapy in the first 2 years, there was a substantial difference after 4 years.

The mSASSS change in scores over 2 years in patients who were and were not treated with a TNF inhibitor for 12 months or more were a respective 0.35 and 0.81 (P = .047) considering treatment in the previous 2-year treatment period, and 0.33 and 0.77 (also P = .047) considering treatment in the prior 2-year treatment period and the current 2-year period.

“Our interpretation is that within the first 2 years we see a resolution of inflammation, a process of repair, maybe even a process of bone formation, but then if you continue this inflammation control for longer than 2 years, then we see the effect on structural damage,” Dr. Poddubnyy said.

SIJ findings

The SIJ analysis included 301 patients who had at least two sets of radiographs taken every 2 years over a 10-year follow-up period, 87 (28.9%) of whom had been treated with at least one TNF inhibitor during follow-up.

Radiographic SIJ progression was defined as the change in the sacroiliitis sum score over 2 years. Calculations considered both the current 2-year period and the previous 2-year period, as well as any use of TNF inhibitors or more than 12 months’ use.

There were no significant differences in sacroiliitis sum scores comparing people who were and were not treated with TNF inhibitors for at least 12 months in the current 2-year period. However, when the previous 2-year period was looked at there was a significant difference in the score between those who had and had not been treated for 12 or more months (0.15 vs. 0.27, respectively; P = .024).

“These data indicate that TNF inhibitors have a late effect,” Dr. Torgutalp said. “You cannot observe the effect of the TNF inhibitor on radiographic progression in the same interval, you have to wait to see this effect in the next interval,” he explained. That means that when a patient uses a TNF inhibitor, you must wait to see the effect on SIJ progression in the subsequent 2 years, he qualified.

Lessons for practice

“If we control inflammation, we might control structural damage progression,” Dr. Poddubnyy said.

If this is the case, then it is likely that other drugs that control inflammation in axSpA will have a similar effect, such as those that target interleukin-17 or Janus kinases. This is something in the future to look at in the GESPIC cohort once enough patient-years of data are available.

Early treatment is probably important, Dr. Poddubnyy suggested, “because in patients with early disease we can expect not that much structural damage at baseline.” Starting treatment early, at the inflammatory stage rather than at the stage where there was a lot of damage already there, could yield better results, he proposed.

“As a clinician, as a researcher, I would be really interested in demonstrating in a prospective, clinical trial that treating patients to target, achieving a remission, would be associated with retardation of structural damage progression. This has only been shown in observational studies so far, so this is an open question.”

Questions on adjustments made for confounding factors

Questions on the spinal presentation included whether there were any differences in NSAID use, to which Dr. Poddubnyy responded, “Patients on TNF inhibitors normally reduce NSAIDs. We adjusted, therefore, for NSAID use.”

The SIJ presentation garnered more questioning. Dr. Torgutalp qualified that both radiographic and nonradiographic patients had been included in the analysis, and “we observe the same effect.”

Asked how clinically relevant the findings were, he noted that, “to the best of our knowledge, this is the first data for sacroiliac joint progression.” The data for spinal progression seem to “reconcile the results from previous investigators,” where there had been some conflicting data on whether 2 or 4 years’ TNF-inhibitor therapy had any effect on radiographic progression.

“I don’t think you’ve adjusted for the baseline level of damage of the SIJ?” queried Pedro Machado, MD, of University College London Hospital. “As you know, in the spine, but also at the SIJ level, the baseline level of damage is usually one of the strongest predictors of further damage.”

This is not something that was adjusted for, Dr. Torgutalp conceded. “We will do it for further analysis,” he said.

Since 2010, GESPIC has been supported by grants from AbbVie. Dr. Poddubnyy reported financial relationships with AbbVie and numerous other pharmaceutical companies. Dr. Torgutalp had no relevant disclosures.

Three or more weeks of oral anticoagulation (OAC) sometimes isn’t up to the job of clearing any potentially embolic left atrial (LA) thrombi before procedures like cardioversion or catheter ablation in patients with atrial fibrillation (AF). Such OAC-defiant LA thrombi aren’t common, nor are they rare enough to ignore, suggests a new meta-analysis that might also have identified features that predispose to them.

Such predictors of LA clots that persist despite OAC could potentially guide selective use of transesophageal echocardiography (TEE) instead of more routine policies to either use or not use TEE for thrombus rule-out before rhythm-control procedures, researchers propose.

Their prevalence was about 2.7% among the study’s more than 14,000 patients who received at least 3 weeks of OAC with either vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) before undergoing TEE.

But OAC-resistant LA thrombi were two- to four-times as common in patients with than without certain features, including AF other than paroxysmal and higher CHADS2 and CHA2DS2-VASc stroke risk-stratification scores.

“TEE imaging in select patients at an elevated risk of LA thrombus, despite anticoagulation status, may be a reasonable approach to minimize the risk of thromboembolic complications following cardioversion or catheter ablation,” propose the study’s authors, led by Antony Lurie, BMSC, Population Health Research Institute, Hamilton, Ont. Their report was published in the June 15 issue of the Journal of the American College of Cardiology.

Guidelines don’t encourage TEE before cardioversion in patients who have been on OAC for at least 3 weeks, the group notes, and policies on TEE use before AF ablation vary widely regardless of anticoagulation status.

The current study suggests that 3 weeks of OAC isn’t enough for a substantial number of patients, who might be put at thromboembolic risk if TEE were to be skipped before rhythm-control procedures.

Conversely, many patients unlikely to have LA thrombi get preprocedure TEE anyway. That can happen “irrespective of how long they’ve been anticoagulated, their pattern of atrial fibrillation, or their stroke risk,” senior author Jorge A. Wong, MD, MPH, Population Health Research Institute and McMaster University, Hamilton, Ont., told this news organization.

But “TEE is an invasive imaging modality, so it is associated with small element of risk.” The current study, Dr. Wong said, points to potential risk-stratification tools clinicians might use to guide more selective TEE screening.

“At sites where TEEs are done all the time for patients undergoing ablation, one could use several of these risk markers to perhaps tailor use of TEE in individuals,” Dr. Wong said. “For example, in people with paroxysmal atrial fibrillation, we found that the risk of left atrial appendage clot was approximately 1% or less.” Screening by TEE might reasonably be avoided in such patients.

“Fortunately, continued oral anticoagulation already yields low peri-procedural stroke rates,” observes an accompanying editorial from Paulus Kirchhof, MD, and Christoph Sinning, MD, from the University Heart & Vascular Center and German Centre of Cardiovascular Research, Hamburg.

“Based on this new analysis of existing data, a risk-based use of TEE imaging in anticoagulated patients could enable further improvement in the safe delivery of rhythm control interventions in patients with AF,” the editorialists agree.

The meta-analysis covered 10 prospective and 25 retrospective studies with a total of 14,653 patients that reported whether LA thrombus was present in patients with AF or atrial flutter (AFL) who underwent TEE after at least 3 weeks of VKA or DOAC therapy. Reports for 30 of the studies identified patients by rhythm-control procedure, and the remaining five didn’t specify TEE indications.

The weighted mean prevalence of LA thrombus at TEE was 2.73% (95% confidence interval, 1.95%-3.80%). The finding was not significantly changed in separate sensitivity analyses, the report says, including one limited to studies with low risk of bias and others excluding patients with valvular AF, interrupted OAC, heparin bridging, or subtherapeutic anticoagulation, respectively.

Patients treated with VKA and DOACs showed similar prevalences of LA thrombi, with means of 2.80% and 3.12%, respectively (P = .674). The prevalence was significantly higher in patients:

• with nonparoxysmal than with paroxysmal AF/AFL (4.81% vs. 1.03%; P < .001)
• undergoing cardioversion than ablation (5.55% vs. 1.65; P < .001)
• with CHA2DS2-VASc scores of at least 3 than with scores of 2 or less (6.31% vs. 1.06%; P < .001).

A limitation of the study, observe Dr. Kirchhof and Dr. Sinning, “is that all patients had a clinical indication for a TEE, which might be a selection bias. When a thrombus was found on TEE, clinical judgment led to postponing of the procedure,” thereby avoiding potential thromboembolism.

“Thus, the paper cannot demonstrate that presence of a thrombus on TEE is related to peri-procedural ischemic stroke,” they write.

The literature puts the risk for stroke or systemic embolism at well under 1% for patients anticoagulated with either VKA or DOACs for at least 3 weeks prior to cardioversion, in contrast to the nearly 3% prevalence of LA appendage thrombus by TEE in the current analysis, Dr. Wong observed.

“So we’re seeing a lot more left atrial appendage thrombus than we would see stroke,” but there wasn’t a way to determine whether that increases the stroke risk, he agreed.Dr. Wong, Dr. Lurie, and the other authors report no relevant conflicts. Dr. Kirchhof discloses receiving partial support “from several drug and device companies active in atrial fibrillation” and to being listed as inventor on two AF-related patents held by the University of Birmingham. Dr. Sinning reports no relevant relationships.

Three or more weeks of oral anticoagulation (OAC) sometimes isn’t up to the job of clearing any potentially embolic left atrial (LA) thrombi before procedures like cardioversion or catheter ablation in patients with atrial fibrillation (AF). Such OAC-defiant LA thrombi aren’t common, nor are they rare enough to ignore, suggests a new meta-analysis that might also have identified features that predispose to them.

Graduates of international medical schools died from COVID-19 in disproportionate numbers in the United States in 2020, researchers report.

“I’ve always felt that international medical graduates [IMGs] in America are largely invisible,” said senior author Abraham Verghese, MD, MFA, an infectious disease specialist at Stanford (Calif.) University. “Everyone is aware that there are foreign doctors, but very few are aware of how many there are and also how vital they are to providing health care in America.”

IMGs made up 25% of all U.S. physicians in 2020 but accounted for 45% of those whose deaths had been attributed to COVID-19 through Nov. 23, 2020, Deendayal Dinakarpandian, MD, PhD, clinical associate professor of medicine at Stanford (Calif.) University, and colleagues report in JAMA Network Open.

IMGs are more likely to work in places where the incidence of COVID-19 is high and in facilities with fewer resources, Dr. Verghese said in an interview. “So, it’s not surprising that they were on the front lines when this thing came along,” he said.

To see whether their vulnerability affected their risk for death, Dr. Dinakarpandian and colleagues collected data from Nov. 23, 2020, from three sources of information regarding deaths among physicians: MedPage Today, which used investigative and voluntary reporting; Medscape, which used voluntary reporting of verifiable information; and a collaboration of The Guardian and Kaiser Health News, which used investigative reporting.

The Medscape project was launched on April 1, 2020. The MedPage Today and The Guardian/Kaiser Health News projects were launched on April 8, 2020.

Dr. Verghese and colleagues researched obituaries and news articles referenced by the three projects to verify their data. They used DocInfo to ascertain the deceased physicians’ medical schools.

After eliminating duplications from the lists, the researchers counted 132 physician deaths in 28 states. Of these, 59 physicians had graduated from medical schools outside the United States, a death toll 1.8 times higher than the proportion of IMGs among U.S. physicians (95% confidence interval, 1.52-2.21; P < .001).

New York, New Jersey, and Florida accounted for 66% of the deaths among IMGs but for only 45% of the deaths among U.S. medical school graduates.

Within each state, the proportion of IMGs among deceased physicians was not statistically different from their proportion among physicians in those states, with the exception of New York.

Two-thirds of the physicians’ deaths occurred in states where IMGs make up a larger proportion of physicians than in the nation as a whole. In these states, the incidence of COVID-19 was high at the start of the pandemic.

In New York, IMGs accounted for 60% of physician deaths, which was 1.62 times higher (95% CI, 1.26-2.09; P = .005) than the 37% among New York physicians overall.

Physicians who were trained abroad frequently can’t get into the most prestigious residency programs or into the highest paid specialties and are more likely to serve in primary care, Dr. Verghese said. Overall, 60% of the physicians who died of COVID-19 worked in primary care.

IMGs often staff hospitals serving low-income communities and communities of color, which were hardest hit by the pandemic and where personal protective equipment was hard to obtain, said Dr. Verghese.

In addition to these risks, IMGs sometimes endure racism, said Dr. Verghese, who obtained his medical degree at Madras Medical College, Chennai, India. “We’ve actually seen in the COVID era, in keeping with the sort of political tone that was set in Washington, that there’s been a lot more abuses of both foreign physicians and foreign looking physicians – even if they’re not foreign trained – and nurses by patients who have been given license. And I want to acknowledge the heroism of all these physicians.”

The study was partially funded by the Presence Center at Stanford. Dr. Verghese is a regular contributor to Medscape. He served on the advisory board for Gilead Sciences, serves as a speaker or a member of a speakers bureau for Leigh Bureau, and receives royalties from Penguin Random House and Simon & Schuster.

Swelling of the heart appears to be a very rare side effect that primarily strikes young people after vaccination for COVID-19, a Centers for Disease Control and Prevention expert reported on June 10, detailing data on cases of myocarditis and pericarditis detected through a government safety system.

The side effect seems to be more common in teen boys and young men than in older adults and women and may occur in 16 cases for every 1 million people who got a second dose, said Tom Shimabukuro, MD, MPH, deputy director of the CDC’s Immunization Safety Office, who presented information on the cases at a meeting of an expert panel that advises the U.S. Food and Drug Administration on vaccines.

Telltale symptoms include chest pain, shortness of breath, and fever.

William Schaffner, MD, an infectious diseases specialist from Vanderbilt University, Nashville, Tenn., thinks certain characteristics are pointing toward a “rare, but real” signal. First, the events are clustering, occurring within days of vaccination. Second, they tend to be more common in males and younger people. Third, he says, the number of events is above the so-called “background rate” – the cases that could be expected in this age group even without vaccination.

“I don’t think we’re quite there yet. We haven’t tied a ribbon around it, but I think the data are trending in that direction,” he said.

The issue of myocarditis weighed heavily on the Vaccines and Related Biological Products Advisory Committee’s considerations of what kind and how much data might be needed to green light use of a vaccine for COVID in children. 

Because the rates of hospitalization for COVID are low in kids, some felt that the FDA should require at least a year of study of the vaccines in clinical trials, the amount of data typically required for full approval, instead of the 2 months currently required for emergency use authorization.  Others wondered whether the risks of vaccination – as low as they are – might outweigh the benefits in this age group.

“I don’t really see this as an emergency in children,” said committee member Michael Kurilla, MD, PhD, the director of clinical innovation at the National Institutes of Health. Dr. Kurilla, however, did say he thought having an expanded access program for children at high risk might make sense.

Most of the young adults who experienced myocarditis recovered quickly, though three needed intensive care and rehabilitation after their episodes. Among cases with known outcomes, 81% got better and 19% still have ongoing symptoms.
 

Adverse events reports

The data on myocarditis come from the Vaccine Adverse Events Reporting System, or VAERS, a database of health problems reported after vaccination. This reporting system, open to anyone, has benefits and limits. It gives the CDC and FDA the ability to rapidly detect potential safety issues, and it is large enough that it can detect rare events, something that’s beyond the power of even large clinical trials. 

But it is observational, so that there’s no way to know if problems reported were caused by the vaccines or a coincidence.

But because VAERS works on an honor system, it can also be spammed, and it carries the bias of the person who’s doing the reporting, from clinicians to average patients. For that reason, Dr. Shimabukuro said they are actively investigating and confirming each report they get. 

Out of more than 12 million doses administered to youth ages 16-24, the CDC says it has 275 reports of heart inflammation following vaccination in this age group. The CDC has analyzed a total 475 cases of myocarditis after vaccination in people under age 30 that were reported to VAERS.

The vaccines linked to the events are the mRNA vaccines made by Pfizer and Moderna. The only vaccines currently authorized for use in adolescents are made by Pfizer. Because the Pfizer vaccine was authorized for use in kids as young as 12 last month, there’s not yet enough data to draw conclusions about the risk of myocarditis in kids ages 12-15.

Younger age groups have only received about 9% of the total doses of the vaccine so far, but they represent about 50% of the myocarditis cases reported after vaccination. “We clearly have an imbalance there,” Dr. Shimabukuro said.

The number of events in this age group appears to be above the rate that would be expected for these age groups without vaccines in the picture, he said, explaining that the number of events are in line with similar adverse events seen in young people in Israel and reported by the Department of Defense. Israel found the incidence of myocarditis after vaccination was 50 cases per million for men ages 18-30.
 

More study needed

Another system tracking adverse events through hospitals, the Vaccine Safety Datalink, didn’t show reports of heart inflammation above numbers that are normally seen in the population, but it did show that inflammation was more likely after a second dose of the vaccine.

“Should this be included in informed consent?” asked Cody Meissner, MD, a pediatric infectious disease specialist at Tufts University, Boston, and a member of the FDA committee. 

“I think it’s hard to deny there seem to be some [events that seem] to be occurring in terms of myocarditis,” he said.

Dr. Meissner said later in the committee’s discussion that his own hospital had recently admitted a 12-year-old boy who developed heart swelling 2 days after the second dose of vaccine with a high level of troponin, an enzyme that indicates damage to the heart. His level was over 9. “A very high level,” Dr. Meissner said.

“Will there be scarring to the myocardium? Will there be a predisposition to arrhythmias later on? Will there be an early onset of heart failure? We think that’s unlikely, but [we] don’t know that,” he said.

The CDC has scheduled an emergency meeting next week to convene an expert panel on immunization practices to further review the events.

In addition to the information presented at the FDA’s meeting, doctors at Oregon Health & Science University, Portland, recently described seven cases in teens – all boys – who developed heart inflammation within 4 days of getting the second dose of the Pfizer vaccine.

The study was published June 10 in Pediatrics. All the boys were hospitalized and treated with anti-inflammatory medications including NSAIDs and steroids. Most were discharged within a few days and all recovered from their symptoms.

Swelling of the heart appears to be a very rare side effect that primarily strikes young people after vaccination for COVID-19, a Centers for Disease Control and Prevention expert reported on June 10, detailing data on cases of myocarditis and pericarditis detected through a government safety system.

The side effect seems to be more common in teen boys and young men than in older adults and women and may occur in 16 cases for every 1 million people who got a second dose, said Tom Shimabukuro, MD, MPH, deputy director of the CDC’s Immunization Safety Office, who presented information on the cases at a meeting of an expert panel that advises the U.S. Food and Drug Administration on vaccines.

Telltale symptoms include chest pain, shortness of breath, and fever.

William Schaffner, MD, an infectious diseases specialist from Vanderbilt University, Nashville, Tenn., thinks certain characteristics are pointing toward a “rare, but real” signal. First, the events are clustering, occurring within days of vaccination. Second, they tend to be more common in males and younger people. Third, he says, the number of events is above the so-called “background rate” – the cases that could be expected in this age group even without vaccination.

“I don’t think we’re quite there yet. We haven’t tied a ribbon around it, but I think the data are trending in that direction,” he said.

The issue of myocarditis weighed heavily on the Vaccines and Related Biological Products Advisory Committee’s considerations of what kind and how much data might be needed to green light use of a vaccine for COVID in children. 

Because the rates of hospitalization for COVID are low in kids, some felt that the FDA should require at least a year of study of the vaccines in clinical trials, the amount of data typically required for full approval, instead of the 2 months currently required for emergency use authorization.  Others wondered whether the risks of vaccination – as low as they are – might outweigh the benefits in this age group.

“I don’t really see this as an emergency in children,” said committee member Michael Kurilla, MD, PhD, the director of clinical innovation at the National Institutes of Health. Dr. Kurilla, however, did say he thought having an expanded access program for children at high risk might make sense.

Most of the young adults who experienced myocarditis recovered quickly, though three needed intensive care and rehabilitation after their episodes. Among cases with known outcomes, 81% got better and 19% still have ongoing symptoms.
 

Adverse events reports

The data on myocarditis come from the Vaccine Adverse Events Reporting System, or VAERS, a database of health problems reported after vaccination. This reporting system, open to anyone, has benefits and limits. It gives the CDC and FDA the ability to rapidly detect potential safety issues, and it is large enough that it can detect rare events, something that’s beyond the power of even large clinical trials. 

But it is observational, so that there’s no way to know if problems reported were caused by the vaccines or a coincidence.

But because VAERS works on an honor system, it can also be spammed, and it carries the bias of the person who’s doing the reporting, from clinicians to average patients. For that reason, Dr. Shimabukuro said they are actively investigating and confirming each report they get. 

Out of more than 12 million doses administered to youth ages 16-24, the CDC says it has 275 reports of heart inflammation following vaccination in this age group. The CDC has analyzed a total 475 cases of myocarditis after vaccination in people under age 30 that were reported to VAERS.

The vaccines linked to the events are the mRNA vaccines made by Pfizer and Moderna. The only vaccines currently authorized for use in adolescents are made by Pfizer. Because the Pfizer vaccine was authorized for use in kids as young as 12 last month, there’s not yet enough data to draw conclusions about the risk of myocarditis in kids ages 12-15.

Younger age groups have only received about 9% of the total doses of the vaccine so far, but they represent about 50% of the myocarditis cases reported after vaccination. “We clearly have an imbalance there,” Dr. Shimabukuro said.

The optimal first step to address mild to moderately elevated blood pressure and cholesterol in otherwise healthy adults is a “prescription” to sit less and move more, the American Heart Association says in a new scientific statement.

“The current American Heart Association guidelines for diagnosing high blood pressure and cholesterol recognize that otherwise healthy individuals with mildly or moderately elevated levels of these cardiovascular risk factors should actively attempt to reduce these risks,” Bethany Barone Gibbs, PhD, chair of the statement writing group, said in an AHA news release.

“The first treatment strategy for many of these patients should be healthy lifestyle changes beginning with increasing physical activity,” said Dr. Gibbs, from the University of Pittsburgh.

The 12-page AHA scientific statement – Physical Activity as a Critical Component of First-Line Treatment for Elevated Blood Pressure or Cholesterol: Who, What, and How? – was published online June 2 in Hypertension.
 

Every little bit helps

According to the AHA, about 21% of American adults have systolic blood pressure between 120 and 139 mm Hg, or diastolic blood pressure between 80 and 89 mm Hg, which meets the criteria for lifestyle-only treatment for elevated BP outlined in the American College of Cardiology (ACC)/AHA high blood pressure guideline.

In addition, about 28% of American adults have LDL cholesterol above 70 mg/dL and otherwise meet the low-risk criteria for heart disease or stroke. These individuals would meet the criteria for lifestyle-only treatment outlined in the 2018 ACC/AHA cholesterol treatment guidelines, which include increased physical activity, weight loss, better diet, smoking cessation, and moderating alcohol intake.

“Of the recommended lifestyle changes, increasing physical activity has extensive benefits, including improving both blood pressure and blood cholesterol, that are comparable, superior, or complementary to other healthy lifestyle changes,” the writing group says.

“Physical activity assessment and prescription are an excellent lifestyle behavior treatment option for all patients, including for the large population of mild-moderate-risk patients with elevated blood pressure and blood cholesterol,” they note.

Research has shown that increasing physical activity can lead to clinically meaningful 3 or 4 mm Hg reductions in systolic and diastolic blood pressure, and 3 to 6 mg/dL decreases in LDL cholesterol, the authors point out.

Previous evidence also shows that physically active people have a 21% lower risk of developing cardiovascular disease and a 36% lower risk for death from cardiovascular diseases than those who are not physically active.

Physical activity also has benefits beyond heart health, including a lower risk for some cancers; improved bone, brain, and mental health; and better sleep, they note.

The U.S. Department of Health and Human Services 2018 physical activity guidelines advise Americans to log 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous aerobic activity each week and to participate in two or more weekly strength training sessions.

However, there is no minimum amount of time to receive benefits from physical activity.

“Every little bit of activity is better than none. Even small initial increases of 5 to 10 minutes a day can yield health benefits,” Dr. Gibbs said.
 

Translational advice for clinicians

The AHA statement encourages clinicians to ask patients about their physical activity at every interaction; provide ideas and resources to help patients improve and sustain regular life-long physical activity; and encourage and celebrate small increases in activity, such as walking more or taking the stairs, to help with motivation.

“In our world where physical activity is increasingly engineered out of our lives and the overwhelming default is to sit – and even more so now as the nation and the world is practicing quarantine and isolation to reduce the spread of coronavirus – the message that we must be relentless in our pursuit to ‘sit less and move more’ throughout the day is more important than ever,” said Dr. Gibbs.

The statement was prepared by a volunteer writing group on behalf of the AHA Council on Lifestyle and Cardiometabolic Health; the Council on Cardiovascular and Stroke Nursing; and the Council on Clinical Cardiology.

This research had no commercial funding. A list of disclosures for the writing group is available with the original article.

For many people, being told that they are HIV positive is no longer a death sentence. But for Robert Suttle, a Black gay man and social justice educator, it is a life sentence.

Unexpectedly caught up in the HIV criminalization web at the age of 30, Mr. Suttle spent 6 months in a Louisiana state prison for a consensual sexual relationship with an adult partner. The crime? Not disclosing his HIV-positive status, a charge that Mr. Suttle says is untrue.

“I did disclose my status to my partner; however, I can’t really answer how they might have received it,” he said.

Today, at the age of 42, Mr. Suttle still carries the indelible stain of a conviction and of being a registered sex offender. “After their diagnosis, criminal charge, and/or conviction, many people think they’re done – either ‘I’ve gotten out of prison’ or ‘I’m still on probation’ – whatever the case may be,” he explained. “But we’re still living out these collateral consequences, be it with housing, moving to another state, or finding a job.”

The same is true for HIV-positive people who are charged and tried but manage to dodge prison for one reason or another. Monique Howell, a straight, 40-year-old former army soldier and single mother of five children, said that she was afraid to disclose her HIV status to a sexual partner but did advise him to wear a condom.* She points to her DD14 discharge papers (i.e., forms that verify that someone served in the military) that were issued when her military duty was rescinded following the dismissal of her court case.

“I was going to reenlist, but I got in trouble,” she said. She explained that although a DD14 separation helps to ensure that she can receive benefits and care, the papers were issued with a caveat stating “serious offense,” an indelible stain that, like Mr. Suttle’s, will follow her for the rest of her life.
 

Laws criminalize myths and misconceptions

HIV criminalization laws subject persons whose behaviors may expose others to HIV to felony or misdemeanor charges. Depending on the state, they can carry prison terms ranging from less than 10 years to life, according to the Centers for Disease Control and Prevention.

Originally enacted at the height of the AIDS epidemic in 1986, when fear was rampant and hundreds were dying, the laws were intended to reduce HIV transmission. But they’ve had unintended consequences: Amplifying stigmatization and discrimination and perpetuating HIV myths and misconceptions, including how HIV is transmitted.

Decades of scientific advances challenge the most basic reasoning behind laws (for example, that transmission is possible via biting or spitting or through a single sexual act, which studies have shown poses a risk as low as 0%-1.4%). In addition, few laws reflect one of the most important HIV research findings of the past decade: undetectable equals untransmittable, meaning that the virus cannot be sexually transmitted by people who are taking antiretroviral therapy and whose viral loads are undetectable.

In most of these cases, individuals who are positive for HIV are charged and punished for unintentional exposure, not deliberate intent to harm. Moreover, for the charge to stick, sexual partners don’t need to have acquired the virus or prove the transmission source if they do become HIV positive.

Ms. Howell noted that it was the Army that brought the charges against her, not her sexual partner at that time (who, incidentally, tested negative). He even testified on her behalf at the trial. “I’ll never forget it,” she said. “He said, ‘I don’t want anything to happen to Monique; even if you put her behind bars, she’s still HIV-positive and she’s still got those children. She told me to get a condom, and I chose not to.’ ”
 

Criminal vs. clinical fallout

In 2018, 20 scientists across the world issued a consensus statement underscoring the fact that HIV criminalization laws are based on fallacies and faulty science. The statement (which remains one of the most accessed in the Journal of the International AIDS Society) also points out that 33 countries (including the United States) use general criminal statutes such as attempted murder or reckless endangerment to lengthen sentences when people with HIV commit crimes.

When the laws were created, “many were the equivalent [to general criminal laws], because HIV was seen as a death sentence,” explained Chris Beyrer MD, MPH, professor of public health and human rights at Johns Hopkins Bloomberg School of Public Health, Baltimore. “So, failure to disclose your status, to wear a condom was seen as risking someone else’s life, which is no longer the case,” he added.

In fact, “from the perspective of the kinds of impact that these laws have had on transmission, or risk, or behavior, what you find is that they really have no public health benefit and they have real public harms,” said Dr. Beyrer.

Claire Farel, MD, assistant professor and medical director of the UNC Infectious Diseases Clinic at the University of North Carolina at Chapel Hill, concurs. “Because of the criminalization undercurrent, there are people who don’t get tested, meaning that they are at risk for worse health outcomes, such as cancer, vascular disease, and of course HIV-related poor outcomes, including progression to AIDS.”

Farel also points to the residual stigma associated with HIV. “Much of this is inextricable from that surrounding homophobia, especially among young men of color who have sex with men. It opens up a larger conversation that a lot of people don’t want to engage in,” she said.
 

Laws broaden existing disparities even further

The CDC released a study June 4 showing substantial declines in the overall incidence of HIV in the United States, with an important caveat: There’s been a worsening disparity in cases. Access to care and engagement with care remain poor among certain populations. For example, Black individuals accounted for 41% of new HIV infections in 2019, but they represent only 12% of the U.S. population; Hispanic/Latinx persons accounted for 29% of new infections, although they represent only 17% of the entire population.

The same is true for HIV criminalization: In 2020, more than 50% of defendants were people of color, according to U.S. case data collated by the HIV Justice Network.

Still, the momentum to change these antiquated laws is gaining speed. In May, the Illinois State Senate passed a bill repealing HIV criminalization, and this past March, Virginia’s Governor Ralph Northam signed a bill lowering HIV-related criminalization charges from a felony to a misdemeanor and changing the wording of its law to include both intent and transmission.** California, Colorado, Iowa, Michigan, Nevada, and North Carolina have also modernized or repealed their laws.
 

Ending the U.S. HIV epidemic: Patients first

Without true HIV criminalization reform, efforts to change the public and clinical mindset regarding HIV from its being a highly stigmatized disease to a preventable, treatable infection are likely to fall short. Dr. Beyrer emphasized that the onus lies with the scientific and activist communities working together. “I don’t know how you can end the epidemic if you are still stigmatizing the people who are actually acquiring these infections,” he said.

There are steps that patients can take while these forces push for change.

“As people first process their diagnosis, they need to learn as much about HIV and the science behind it as possible,” advised Mr. Suttle. He said that to protect oneself, it’s essential to learn about HIV criminalization and the laws in one’s state.

“Find someone you can trust, starting with your medical provider if possible, and if you have a significant other, bring that person to your appointments so they can see that you are in care and doing all that you can do to lower viral loads and protect others,” he added.

Ms. Howell said that although people should be in treatment and care, attitudes also need to change on the clinician side. “We’re just given these meds, told to take them, and are sent on our merry ways, but they don’t tell us how to live our lives properly; nobody grabs us and says, hey, these are the laws and you need to know this or that.”

When a person who is HIV positive does get caught up in the system, if possible, that person should consult an attorney who understands these laws.

For many people, being told that they are HIV positive is no longer a death sentence. But for Robert Suttle, a Black gay man and social justice educator, it is a life sentence.

Unexpectedly caught up in the HIV criminalization web at the age of 30, Mr. Suttle spent 6 months in a Louisiana state prison for a consensual sexual relationship with an adult partner. The crime? Not disclosing his HIV-positive status, a charge that Mr. Suttle says is untrue.

“I did disclose my status to my partner; however, I can’t really answer how they might have received it,” he said.

Today, at the age of 42, Mr. Suttle still carries the indelible stain of a conviction and of being a registered sex offender. “After their diagnosis, criminal charge, and/or conviction, many people think they’re done – either ‘I’ve gotten out of prison’ or ‘I’m still on probation’ – whatever the case may be,” he explained. “But we’re still living out these collateral consequences, be it with housing, moving to another state, or finding a job.”

The same is true for HIV-positive people who are charged and tried but manage to dodge prison for one reason or another. Monique Howell, a straight, 40-year-old former army soldier and single mother of five children, said that she was afraid to disclose her HIV status to a sexual partner but did advise him to wear a condom.* She points to her DD14 discharge papers (i.e., forms that verify that someone served in the military) that were issued when her military duty was rescinded following the dismissal of her court case.

“I was going to reenlist, but I got in trouble,” she said. She explained that although a DD14 separation helps to ensure that she can receive benefits and care, the papers were issued with a caveat stating “serious offense,” an indelible stain that, like Mr. Suttle’s, will follow her for the rest of her life.
 

Laws criminalize myths and misconceptions

HIV criminalization laws subject persons whose behaviors may expose others to HIV to felony or misdemeanor charges. Depending on the state, they can carry prison terms ranging from less than 10 years to life, according to the Centers for Disease Control and Prevention.

Originally enacted at the height of the AIDS epidemic in 1986, when fear was rampant and hundreds were dying, the laws were intended to reduce HIV transmission. But they’ve had unintended consequences: Amplifying stigmatization and discrimination and perpetuating HIV myths and misconceptions, including how HIV is transmitted.

Decades of scientific advances challenge the most basic reasoning behind laws (for example, that transmission is possible via biting or spitting or through a single sexual act, which studies have shown poses a risk as low as 0%-1.4%). In addition, few laws reflect one of the most important HIV research findings of the past decade: undetectable equals untransmittable, meaning that the virus cannot be sexually transmitted by people who are taking antiretroviral therapy and whose viral loads are undetectable.

In most of these cases, individuals who are positive for HIV are charged and punished for unintentional exposure, not deliberate intent to harm. Moreover, for the charge to stick, sexual partners don’t need to have acquired the virus or prove the transmission source if they do become HIV positive.

Ms. Howell noted that it was the Army that brought the charges against her, not her sexual partner at that time (who, incidentally, tested negative). He even testified on her behalf at the trial. “I’ll never forget it,” she said. “He said, ‘I don’t want anything to happen to Monique; even if you put her behind bars, she’s still HIV-positive and she’s still got those children. She told me to get a condom, and I chose not to.’ ”
 

Criminal vs. clinical fallout

In 2018, 20 scientists across the world issued a consensus statement underscoring the fact that HIV criminalization laws are based on fallacies and faulty science. The statement (which remains one of the most accessed in the Journal of the International AIDS Society) also points out that 33 countries (including the United States) use general criminal statutes such as attempted murder or reckless endangerment to lengthen sentences when people with HIV commit crimes.

When the laws were created, “many were the equivalent [to general criminal laws], because HIV was seen as a death sentence,” explained Chris Beyrer MD, MPH, professor of public health and human rights at Johns Hopkins Bloomberg School of Public Health, Baltimore. “So, failure to disclose your status, to wear a condom was seen as risking someone else’s life, which is no longer the case,” he added.

In fact, “from the perspective of the kinds of impact that these laws have had on transmission, or risk, or behavior, what you find is that they really have no public health benefit and they have real public harms,” said Dr. Beyrer.

Claire Farel, MD, assistant professor and medical director of the UNC Infectious Diseases Clinic at the University of North Carolina at Chapel Hill, concurs. “Because of the criminalization undercurrent, there are people who don’t get tested, meaning that they are at risk for worse health outcomes, such as cancer, vascular disease, and of course HIV-related poor outcomes, including progression to AIDS.”

Farel also points to the residual stigma associated with HIV. “Much of this is inextricable from that surrounding homophobia, especially among young men of color who have sex with men. It opens up a larger conversation that a lot of people don’t want to engage in,” she said.
 

Laws broaden existing disparities even further

The CDC released a study June 4 showing substantial declines in the overall incidence of HIV in the United States, with an important caveat: There’s been a worsening disparity in cases. Access to care and engagement with care remain poor among certain populations. For example, Black individuals accounted for 41% of new HIV infections in 2019, but they represent only 12% of the U.S. population; Hispanic/Latinx persons accounted for 29% of new infections, although they represent only 17% of the entire population.

The same is true for HIV criminalization: In 2020, more than 50% of defendants were people of color, according to U.S. case data collated by the HIV Justice Network.

Still, the momentum to change these antiquated laws is gaining speed. In May, the Illinois State Senate passed a bill repealing HIV criminalization, and this past March, Virginia’s Governor Ralph Northam signed a bill lowering HIV-related criminalization charges from a felony to a misdemeanor and changing the wording of its law to include both intent and transmission.** California, Colorado, Iowa, Michigan, Nevada, and North Carolina have also modernized or repealed their laws.
 

Ending the U.S. HIV epidemic: Patients first

Without true HIV criminalization reform, efforts to change the public and clinical mindset regarding HIV from its being a highly stigmatized disease to a preventable, treatable infection are likely to fall short. Dr. Beyrer emphasized that the onus lies with the scientific and activist communities working together. “I don’t know how you can end the epidemic if you are still stigmatizing the people who are actually acquiring these infections,” he said.

There are steps that patients can take while these forces push for change.

“As people first process their diagnosis, they need to learn as much about HIV and the science behind it as possible,” advised Mr. Suttle. He said that to protect oneself, it’s essential to learn about HIV criminalization and the laws in one’s state.

“Find someone you can trust, starting with your medical provider if possible, and if you have a significant other, bring that person to your appointments so they can see that you are in care and doing all that you can do to lower viral loads and protect others,” he added.

Ms. Howell said that although people should be in treatment and care, attitudes also need to change on the clinician side. “We’re just given these meds, told to take them, and are sent on our merry ways, but they don’t tell us how to live our lives properly; nobody grabs us and says, hey, these are the laws and you need to know this or that.”

When a person who is HIV positive does get caught up in the system, if possible, that person should consult an attorney who understands these laws. Mr. Suttle suggested reaching out to organizations in the movement to end HIV criminalization (e.g., the Sero Project, the Center for HIV Law and Policy, or the Positive Women’s Network) for further support, help with cases (including providing experts to testify), social services, and other resources. Mr. Suttle also encourages people who need help and direction to reach out to him directly at [email protected].

Forty years ago, the CDC published its first report of an illness in five healthy gay men living in Los Angeles. The first cases in women were reported shortly thereafter. Over the years, there have been many scientific advances in prevention and treatment. But as Dr. Beyrer aptly noted in an editorial published January 2021 in The Lancet HIV, “time has not lessened the sting of the early decades of AIDS.”

“We should not have to be afraid of who we are because we are HIV positive,” said Ms. Howell.

A new clinical score has been developed, and externally validated, to identify patients at risk of bleeding after transcatheter aortic valve replacement (TAVR).

“Despite the TAVR iterations, we recognize that bleeding remains a very important and perhaps also neglected issue. Indeed, no specifically developed standard algorithm existed before this to assess bleeding risk post-TAVR,” lead author Eliano Pio Navarese, MD, PhD, said in an interview.

Although bleeding rates can be as high as 9% at 30 days and between 3% and 11% in the first year, only a few studies have applied existing scores to TAVR patients, he noted.

The PREDICT-TAVR score includes six common variables and can be calculated by hand using a simple nomogram or a web-based calculator, with a dedicated website in the works, said Dr. Navarese, Nicolaus Copernicus University and SIRO MEDICINE Network, Bydgoszcz, Poland, and the University of Alberta, Edmonton.

A strength of the score is that machine-learning methods were used and the choice of variables optimized through recursive feature elimination and cross validation to remove the weakest variables, he said. Artificial intelligence, including use of random forest, naïve Bayes, and logistic regression classifiers, was also applied to the algorithms and the results cross-checked with standard multivariate analysis.

“It was a tremendous effort in terms of the analytics conducted,” Dr. Navarese said. “This is not a simple score but the integration of the most sophisticated machine learning methods and algorithms.”

Details are published in the June 14 issue of JACC: Cardiovascular Interventions.

The six variables used to calculate 30-day bleeding risk after TAVR and the points assigned to each are:

• blood hemoglobin (0-10 points)
• serum iron concentration (0-5 points)
• common femoral artery diameter (0-3 points)
•  (0-3 points)
• dual antiplatelet therapy (DAPT; 0-2 points)
• oral anticoagulation therapy (0-2 points)

The six items were selected among 104 baseline variables from 5,185 consecutive patients undergoing transfemoral TAVR in the prospective RISPEVA (Registro Italiano GISE sull’Impianto di Valvola Aortica Percutanea) registry between March 2012 and December 2019, then validated in 5,043 patients in the prospective POL-TAVI (Polish Registry of Transcatheter Aortic Valve Implantation) between January 2013 and December 2019.

In the derivation cohort, 216 patients (4.2%) experienced bleeding events at 1 year, with 169 events (78%) occurring during the first 30 days.

PREDICT-TAVR exhibited high discriminatory power for bleeding events at 30 days, as reflected by an area under the curve (AUC) of 0.80 (95% confidence interval, 0.75-0.83). Internal validation by optimism bootstrap-corrected AUC was consistent at 0.79 (95% CI, 0.75-0.83).

PREDICT-TAVR also outperformed scores not developed for TAVR, such as the PARIS score for patients undergoing percutaneous coronary intervention (AUC, 0.69) and the well-validated HAS-BLED for patients receiving anticoagulation (AUC, 0.58; P < .001 for both).

In the validation cohort, the AUC for bleeding complications at 30 days was 0.78 (95% CI, 0.72-0.82) versus an AUC of 0.68 for PARIS and 0.66 for HAS-BLED.

A HAS-BLED score of 4 predicted a higher rate of severe bleeding and mortality in the year after transfemoral TAVR in the 2018 Japanese OCEAN-TAVI study.
 

Bleeding events by risk categories

Risk score quartiles identified as low risk were 8 points or less, as moderate risk were 8 to less than 10 points, as high risk were 10 to less than 12 points, and as very-high-risk score were above 12 points.

In the derivation cohort, 30-day bleeding events across quartiles were 0.8%, 1.1%, 2.5%, and 8.5%, respectively (overall P < .001).

Compared with the lowest quartile, bleeding risk was numerically higher for the second quartile (odds ratio, 1.75) and significantly higher in the third (OR, 2.0) and fourth (OR, 2.49) quartiles (P < .001 for both).

A landmark cumulative-event analysis showed a significantly greater risk of bleeding for the two highest quartiles up to 30 days; however, these differences were no longer significant from 30 days to 1 year, likely because of a limited number of events, the authors suggest. Similar results were seen in the validation cohort.

The number of patients in the high- and very-high-risk groups isn’t trivial, and bleeding rates reached as high as 12.6% in the highest quartile, Dr. Navarese observed. Guidelines recommend DAPT for 3 to 6 months after TAVR; however, emerging data, including a recent meta-analysis, suggest monotherapy may be a very good option.

“So, if you had a high bleeding risk and are considering postprocedural DAPT or anticoagulation, I would think twice rather than administering dual antiplatelet therapy or anticoagulation for a long time, or at least, I would consider the impact of this score on this choice,” he said.

Subgroup analyses showed AUCs ranging from 0.77 to 0.81 for subgroups such as age older than 80 years, diabetes, obesity, female sex, previous PCI, and New York Heart Association class III or IV.

Serum iron showed the highest AUC in the primary PREDICT-TAVR model; however, should iron levels be unavailable, a simplified score modeled without iron levels retained predictive power, yielding AUCs for 30-day bleeding of 0.78 in the derivation cohort and 0.75 in the validation cohort.

“PREDICT-TAVR score can impact clinical practice, not only selecting the optimal thrombotic regimen in certain high bleeding-risk populations but also to treat pre-TAVR anemia and iron deficiencies, which may affect outcomes,” Dr. Navarese said. “Of course, future prospective biological and clinical investigations are needed to elucidate the score and the role of the score’s treatable risk traits in reducing post-TAVR bleeding complications.”

Commenting for this news organization, Sunil Rao, MD, Duke University, Durham, N.C., said anemia is a covariant in many risk models for bleeding and vascular complications in PCI and acute coronary syndrome, but hemoglobin and iron levels are collinear.

“The problem I think is when you throw hemoglobin and iron in the same model, just by play of chance, one variable can knock out the other one,” he said. “So I don’t know necessarily if we need to start measuring iron on everyone. We certainly should be measuring hemoglobin, which I think most people will have, and if a patient has pre-existing anemia, that should be a red flag for us.”

Age and Society of Thoracic Surgeons (STS) risk score did not reach statistical significance in the model – likely reflecting the high-/extremely-high-risk patient population with an average STS score of 7.7 and average age of 82 years – but may become more important as TAVR is applied more widely, Dr. Rao and Zachary Wegermann, MD, Duke Clinical Research Institute, write in an accompanying editorial.

They also point out that the study was limited by a low rate of bleeding events, and, importantly, the score can’t distinguish between minor or major bleeding.

“It’s worth trying to repeat the analyses in lower-risk patients because we may find other covariates that are important,” Dr. Rao said in an interview. “The other thing we need to get to is probably being a little bit more sophisticated. The variables included in these models are the ones that are measured; they’re also the ones that are clinically apparent.”

“But there’s a whole area of genomic medicine, proteomic medicine, metabolomic medicine that, as it starts developing and becomes more and more sophisticated, my suspicion is that we’re going to get even more precise and accurate about patients’ risk, and it’s going to become more individualized, rather than just measuring variables like age and lab values,” he said.

In the meantime, having variables documented in the electronic health record, with hard stops deployed if variables aren’t measured, is “a step in the right direction,” he added.

Dr. Navarese has received research grants from Abbott, Amgen, and Medtronic and received lecture fees and honoraria from Amgen, AstraZeneca, Bayer, Pfizer, and Sanofi-Regeneron, outside the submitted work. Dr. Rao and Dr. Wegermann report no relevant financial disclosures.

“So, if you had a high bleeding risk and are considering postprocedural DAPT or anticoagulation, I would think twice rather than administering dual antiplatelet therapy or anticoagulation for a long time, or at least, I would consider the impact of this score on this choice,” he said.

Subgroup analyses showed AUCs ranging from 0.77 to 0.81 for subgroups such as age older than 80 years, diabetes, obesity, female sex, previous PCI, and New York Heart Association class III or IV.

Serum iron showed the highest AUC in the primary PREDICT-TAVR model; however, should iron levels be unavailable, a simplified score modeled without iron levels retained predictive power, yielding AUCs for 30-day bleeding of 0.78 in the derivation cohort and 0.75 in the validation cohort.

“PREDICT-TAVR score can impact clinical practice, not only selecting the optimal thrombotic regimen in certain high bleeding-risk populations but also to treat pre-TAVR anemia and iron deficiencies, which may affect outcomes,” Dr. Navarese said. “Of course, future prospective biological and clinical investigations are needed to elucidate the score and the role of the score’s treatable risk traits in reducing post-TAVR bleeding complications.”

Commenting for this news organization, Sunil Rao, MD, Duke University, Durham, N.C., said anemia is a covariant in many risk models for bleeding and vascular complications in PCI and acute coronary syndrome, but hemoglobin and iron levels are collinear.

“The problem I think is when you throw hemoglobin and iron in the same model, just by play of chance, one variable can knock out the other one,” he said. “So I don’t know necessarily if we need to start measuring iron on everyone. We certainly should be measuring hemoglobin, which I think most people will have, and if a patient has pre-existing anemia, that should be a red flag for us.”

Age and Society of Thoracic Surgeons (STS) risk score did not reach statistical significance in the model – likely reflecting the high-/extremely-high-risk patient population with an average STS score of 7.7 and average age of 82 years – but may become more important as TAVR is applied more widely, Dr. Rao and Zachary Wegermann, MD, Duke Clinical Research Institute, write in an accompanying editorial.

They also point out that the study was limited by a low rate of bleeding events, and, importantly, the score can’t distinguish between minor or major bleeding.

“It’s worth trying to repeat the analyses in lower-risk patients because we may find other covariates that are important,” Dr. Rao said in an interview. “The other thing we need to get to is probably being a little bit more sophisticated. The variables included in these models are the ones that are measured; they’re also the ones that are clinically apparent.”

“But there’s a whole area of genomic medicine, proteomic medicine, metabolomic medicine that, as it starts developing and becomes more and more sophisticated, my suspicion is that we’re going to get even more precise and accurate about patients’ risk, and it’s going to become more individualized, rather than just measuring variables like age and lab values,” he said.

In the meantime, having variables documented in the electronic health record, with hard stops deployed if variables aren’t measured, is “a step in the right direction,” he added.

A new clinical score has been developed, and externally validated, to identify patients at risk of bleeding after transcatheter aortic valve replacement (TAVR).

“Despite the TAVR iterations, we recognize that bleeding remains a very important and perhaps also neglected issue. Indeed, no specifically developed standard algorithm existed before this to assess bleeding risk post-TAVR,” lead author Eliano Pio Navarese, MD, PhD, said in an interview.

Although bleeding rates can be as high as 9% at 30 days and between 3% and 11% in the first year, only a few studies have applied existing scores to TAVR patients, he noted.

The PREDICT-TAVR score includes six common variables and can be calculated by hand using a simple nomogram or a web-based calculator, with a dedicated website in the works, said Dr. Navarese, Nicolaus Copernicus University and SIRO MEDICINE Network, Bydgoszcz, Poland, and the University of Alberta, Edmonton.

A strength of the score is that machine-learning methods were used and the choice of variables optimized through recursive feature elimination and cross validation to remove the weakest variables, he said. Artificial intelligence, including use of random forest, naïve Bayes, and logistic regression classifiers, was also applied to the algorithms and the results cross-checked with standard multivariate analysis.

“It was a tremendous effort in terms of the analytics conducted,” Dr. Navarese said. “This is not a simple score but the integration of the most sophisticated machine learning methods and algorithms.”

Details are published in the June 14 issue of JACC: Cardiovascular Interventions.

The six variables used to calculate 30-day bleeding risk after TAVR and the points assigned to each are:

• blood hemoglobin (0-10 points)
• serum iron concentration (0-5 points)
• common femoral artery diameter (0-3 points)
•  (0-3 points)
• dual antiplatelet therapy (DAPT; 0-2 points)
• oral anticoagulation therapy (0-2 points)

The six items were selected among 104 baseline variables from 5,185 consecutive patients undergoing transfemoral TAVR in the prospective RISPEVA (Registro Italiano GISE sull’Impianto di Valvola Aortica Percutanea) registry between March 2012 and December 2019, then validated in 5,043 patients in the prospective POL-TAVI (Polish Registry of Transcatheter Aortic Valve Implantation) between January 2013 and December 2019.

In the derivation cohort, 216 patients (4.2%) experienced bleeding events at 1 year, with 169 events (78%) occurring during the first 30 days.

PREDICT-TAVR exhibited high discriminatory power for bleeding events at 30 days, as reflected by an area under the curve (AUC) of 0.80 (95% confidence interval, 0.75-0.83). Internal validation by optimism bootstrap-corrected AUC was consistent at 0.79 (95% CI, 0.75-0.83).

PREDICT-TAVR also outperformed scores not developed for TAVR, such as the PARIS score for patients undergoing percutaneous coronary intervention (AUC, 0.69) and the well-validated HAS-BLED for patients receiving anticoagulation (AUC, 0.58; P < .001 for both).

In the validation cohort, the AUC for bleeding complications at 30 days was 0.78 (95% CI, 0.72-0.82) versus an AUC of 0.68 for PARIS and 0.66 for HAS-BLED.

A HAS-BLED score of 4 predicted a higher rate of severe bleeding and mortality in the year after transfemoral TAVR in the 2018 Japanese OCEAN-TAVI study.
 

Bleeding events by risk categories

Risk score quartiles identified as low risk were 8 points or less, as moderate risk were 8 to less than 10 points, as high risk were 10 to less than 12 points, and as very-high-risk score were above 12 points.

In the derivation cohort, 30-day bleeding events across quartiles were 0.8%, 1.1%, 2.5%, and 8.5%, respectively (overall P < .001).

Compared with the lowest quartile, bleeding risk was numerically higher for the second quartile (odds ratio, 1.75) and significantly higher in the third (OR, 2.0) and fourth (OR, 2.49) quartiles (P < .001 for both).

A landmark cumulative-event analysis showed a significantly greater risk of bleeding for the two highest quartiles up to 30 days; however, these differences were no longer significant from 30 days to 1 year, likely because of a limited number of events, the authors suggest. Similar results were seen in the validation cohort.

The number of patients in the high- and very-high-risk groups isn’t trivial, and bleeding rates reached as high as 12.6% in the highest quartile, Dr. Navarese observed. Guidelines recommend DAPT for 3 to 6 months after TAVR; however, emerging data, including a recent meta-analysis, suggest monotherapy may be a very good option.
