High obesity rates in Southern states magnify COVID threats

In January, as Mississippi health officials planned for their incoming shipments of COVID-19 vaccine, they assessed the state’s most vulnerable: health care workers, of course, and elderly people in nursing homes. But among those who needed urgent protection from the virus ripping across the Magnolia State were 1 million Mississippians with obesity.

Obesity and weight-related illnesses have been deadly liabilities in the COVID era. A report released this month by the World Obesity Federation found that increased body weight is the second-greatest predictor of COVID-related hospitalization and death across the globe, trailing only old age as a risk factor.

As a fixture of life in the American South – home to 9 of the nation’s 12 heaviest states – obesity is playing a role not only in COVID outcomes, but in the calculus of the vaccination rollout. Mississippi was one of the first states to add a body mass index of 30 or more (a rough gauge of obesity tied to height and weight) to the list of qualifying medical conditions for a shot. About 40% of the state’s adults meet that definition, according to federal health survey data, and combined with the risk group already eligible for vaccination – residents 65 and older – that means fully half of Mississippi’s adults are entitled to vie for a restricted allotment of shots.

At least 29 states have green-lighted obesity for inclusion in the first phases of the vaccine rollout, according to KFF – a vast widening of eligibility that has the potential to overwhelm government efforts and heighten competition for scarce doses.

“We have a lifesaving intervention, and we don’t have enough of it,” said Jen Kates, PhD, director of global health and HIV policy for Kaiser Family Foundation. “Hard choices are being made about who should go first, and there is no right answer.”

The sheer prevalence of obesity in the nation – two in three Americans exceed what is considered a healthy weight – was a public health concern well before the pandemic. But COVID-19 dramatically fast-tracked the discussion from warnings about the long-term damage excess fat tissue can pose to heart, lung and metabolic functions to far more immediate threats.

In the United Kingdom, for example, overweight COVID patients were 67% more likely to require intensive care, and obese patients three times likelier, according to the World Obesity Federation report. A Centers for Disease Control and Prevention study released Monday found a similar trend among U.S. patients and noted that the risk of COVID-related hospitalization, ventilation and death increased with patients’ obesity level.

The counties that hug the southern Mississippi River are home to some of the most concentrated pockets of extreme obesity in the United States. Coronavirus infections began surging in Southern states early last summer, and hospitalizations rose in step.

Deaths in rural stretches of Arkansas, Louisiana, Mississippi, and Tennessee have been overshadowed by the sheer number of deaths in metropolitan areas like New York, Los Angeles, and Essex County, N.J. But as a share of the population, the coronavirus has been similarly unsparing in many Southern communities. In sparsely populated Claiborne County, Miss., on the floodplains of the Mississippi River, 30 residents – about 1 in 300 – had died as of early March. In East Feliciana Parish, La., north of Baton Rouge, with 106 deaths, about 1 in 180 had died by then.

“It’s just math. If the population is more obese and obesity clearly contributes to worse outcomes, then neighborhoods, cities, states and countries that are more obese will have a greater toll from COVID,” said Dr. James de Lemos, MD, a professor of internal medicine at UT Southwestern Medical Center in Dallas who led a study of hospitalized COVID patients published in the medical journal Circulation.

And, because in the U.S. obesity rates tend to be relatively high among African Americans and Latinos who are poor, with diminished access to health care, “it’s a triple whammy,” Dr. de Lemos said. “All these things intersect.”

Poverty and limited access to medical care are common features in the South, where residents like Michelle Antonyshyn, a former registered nurse and mother of seven in Salem, Ark., say they are afraid of the virus. Ms. Antonyshyn, 49, has obesity and debilitating pain in her knees and back, though she does not have high blood pressure or diabetes, two underlying conditions that federal health officials have determined are added risk factors for severe cases of COVID-19.

Still, she said, she “was very concerned just knowing that being obese puts you more at risk for bad outcomes such as being on a ventilator and death.” As a precaution, Ms. Antonyshyn said, she and her large brood locked down early and stopped attending church services in person, watching online instead.

“It’s not the same as having fellowship, but the risk for me was enough,” said Ms. Antonyshyn.

Governors throughout the South seem to recognize that weight can contribute to COVID-19 complications and have pushed for vaccine eligibility rules that prioritize obesity. But on the ground, local health officials are girding for having to tell newly eligible people who qualify as obese that there aren’t enough shots to go around.

In Port Gibson, Miss., Mheja Williams, MD, medical director of the Claiborne County Family Health Center, has been receiving barely enough doses to inoculate the health workers and oldest seniors in her county of 9,600. One week in early February, she received 100 doses.

Obesity and extreme obesity are endemic in Claiborne County, and health officials say the “normalization” of obesity means people often don’t register their weight as a risk factor, whether for COVID or other health issues. The risks are exacerbated by a general flouting of pandemic etiquette: Dr. Williams said that middle-aged and younger residents are not especially vigilant about physical distancing and that mask use is rare.

The rise of obesity in the United States is well documented over the past half-century, as the nation turned from a diet of fruits, vegetables and limited meats to one laden with ultra-processed foods and rich with salt, fat, sugar, and flavorings, along with copious amounts of meat, fast food, and soda. The U.S. has generally led the global obesity race, setting records as even toddlers and young children grew implausibly, dangerously overweight.

Well before COVID, obesity was a leading cause of preventable death in the United States. The National Institutes of Health declared it a disease in 1998, one that fosters heart disease, stroke, type 2 diabetes, and breast, colon, and other cancers.

Researchers say it is no coincidence that nations like the United States, the United Kingdom, and Italy, with relatively high obesity rates, have proved particularly vulnerable to the novel coronavirus.

They believe the virus may exploit underlying metabolic and physiological impairments that often exist in concert with obesity. Extra fat can lead to a cascade of metabolic disruptions, chronic systemic inflammation, and hormonal dysregulation that may thwart the body’s response to infection.

Other respiratory viruses, like influenza and SARS, which appeared in China in 2002, rely on cholesterol to spread enveloped RNA virus to neighboring cells, and researchers have proposed that a similar mechanism may play a role in the spread of the novel coronavirus.

There are also practical problems for coronavirus patients with obesity admitted to the hospital. They can be more difficult to intubate because of excess central weight pressing down on the diaphragm, making breathing with infected lungs even more difficult.

Physicians who specialize in treating patients with obesity say public health officials need to be more forthright and urgent in their messaging, telegraphing the risks of this COVID era.

“It should be explicit and direct,” said Fatima Stanford, MD, an obesity medicine specialist at Massachusetts General Hospital, Boston, and a Harvard Medical School instructor.

Dr. Stanford denounces the fat-shaming and bullying that people with obesity often experience. But telling patients – and the public – that obesity increases the risk of hospitalization and death is crucial, she said.

“I don’t think it’s stigmatizing,” she said. “If you tell them in that way, it’s not to scare you, it’s just giving information. Sometimes people are just unaware.”

Colchicine before PCI for acute MI fails to improve major outcomes

Article Type
Changed

 

In a placebo-controlled randomized trial, a preprocedural dose of colchicine administered immediately before percutaneous coronary intervention (PCI) for an acute ST-segment elevated myocardial infarction (STEMI) did not reduce the no-reflow phenomenon or improve outcomes.

No-reflow, in which insufficient myocardial perfusion is present even though the coronary artery appears patent, was the primary outcome, and the proportion of patients experiencing this event was exactly the same (14.4%) in the colchicine and placebo groups, reported Yaser Jenab, MD, at CRT 2021 sponsored by MedStar Heart & Vascular Institute.

The hypothesis that colchicine would offer benefit in this setting was largely based on the Colchicine Cardiovascular Outcomes Trial (COLCOT). In that study, colchicine was associated with a 23% reduction in risk for major adverse cardiovascular events (MACE) relative to placebo when administered within 30 days after a myocardial infarction (hazard ratio, 0.77; P = .02).

The benefit in that trial was attributed to an anti-inflammatory effect, according to Dr. Jenab, associate professor of cardiology at Tehran (Iran) Heart Center. In particular as it relates to vascular disease, he cited experimental studies associating colchicine with a reduction in neutrophil activation and adherence to vascular endothelium.

The rationale for a preprocedural approach to colchicine was supplied by a subsequent time-to-treatment COLCOT analysis. In this study, MACE risk reduction for colchicine climbed to 48% (HR 0.52) for those treated within 3 days of the MI but largely disappeared (HR 0.96) if treatment was started at least 8 days post MI.
 

PodCAST-PCI trial

In the preprocedural study, called the PodCAST-PCI trial, 321 acute STEMI patients were randomized. Patients received a 1-mg dose of oral colchicine or placebo at the time PCI was scheduled. Another dose of colchicine (0.5 mg) or placebo was administered 1 hour after the procedure.

Of secondary outcomes, which included MACE at 1 month and 1 year, ST-segment resolution at 1 month, and change in inflammatory markers at 1 month, none were significant. Few even trended for significance.

For MACE, which included cardiac death, stroke, nonfatal MI, new hospitalization due to heart failure, or target vessel revascularization, the rates were lower in the colchicine group at 1 month (4.3% vs. 7.5%) and 1 year (9.3% vs. 11.2%), but neither approached significance.

For ST-segment resolution, the proportions were generally comparable among the colchicine and placebo groups, respectively, for the proportion below 50% (18.6% vs. 23.1%), between 50% and 70% (16.8% vs. 15.6%), and above 70% (64.6% vs. 61.3%).

The average troponin levels were nonsignificantly lower at 6 hours (1,847 vs. 2,883 ng/mL) in the colchicine group but higher at 48 hours (1,197 vs. 1,147 ng/mL). The average C-reactive protein (CRP) levels at 48 hours were nonsignificantly lower on colchicine (176.5 vs. 244.5 mg/L).

There were no significant differences in postprocedural perfusion, as measured with TIMI blood flow, or in the rate of stent thrombosis, which occurred in roughly 3% of each group of patients.

The small sample size was one limitation of this study, Dr. Jenab acknowledged. For this and other reasons, he cautioned that these data are not definitive and do not preclude a benefit on clinical outcomes in a study with a larger size, a different design, or different dosing.
 

 

 

Timing might be the issue

However, even if colchicine has a potential benefit in this setting, timing might be a major obstacle, according to Binata Shah, MD, associate director of research for the Cardiac Catheterization Laboratory at New York University.

Dr. Binita Shah

“We have learned from our rheumatology colleagues that peak plasma levels of colchicine are not achieved for at least 1 hour after the full loading dose,” Dr. Shah said. “With us moving so quickly in a primary PCI setting, it is hard to imagine that colchicine would have had time to really kick in and exert its anti-inflammatory effect.”

Indeed, the problem might be worse than reaching the peak plasma level.

“Even though peak plasma levels occur as early as 1 hour after a full loading dose, we see that it takes about 24 hours to really see the effects translate downstream into more systemic inflammatory markers such as CRP and interleukin-6,” she added. If lowering these signals of inflammation is predictive of benefit, than this might be the biggest obstacle to benefit from colchicine in an urgent treatment setting.

Dr. Jenab and Dr. Shah reported no potential conflicts of interest.

No-reflow, in which insufficient myocardial perfusion is present even though the coronary artery appears patent, was the primary outcome, and the proportion of patients experiencing this event was exactly the same (14.4%) in the colchicine and placebo groups, reported Yaser Jenab, MD, at CRT 2021 sponsored by MedStar Heart & Vascular Institute.

The hypothesis that colchicine would offer benefit in this setting was largely based on the Colchicine Cardiovascular Outcomes Trial (COLCOT). In that study, colchicine was associated with a 23% reduction in risk for major adverse cardiovascular events (MACE) relative to placebo when administered within 30 days after a myocardial infarction (hazard ratio, 0.77; P = .02).

The benefit in that trial was attributed to an anti-inflammatory effect, according to Dr. Jenab, associate professor of cardiology at Tehran (Iran) Heart Center. In particular as it relates to vascular disease, he cited experimental studies associating colchicine with a reduction in neutrophil activation and adherence to vascular endothelium.

The rationale for a preprocedural approach to colchicine was supplied by a subsequent time-to-treatment COLCOT analysis. In this study, MACE risk reduction for colchicine climbed to 48% (HR 0.52) for those treated within 3 days of the MI but largely disappeared (HR 0.96) if treatment was started at least 8 days post MI.
 

PodCAST-PCI trial

In the preprocedural study, called the PodCAST-PCI trial, 321 acute STEMI patients were randomized. Patients received a 1-mg dose of oral colchicine or placebo at the time PCI was scheduled. Another dose of colchicine (0.5 mg) or placebo was administered 1 hour after the procedure.

Of secondary outcomes, which included MACE at 1 month and 1 year, ST-segment resolution at 1 month, and change in inflammatory markers at 1 month, none were significant. Few even trended for significance.

For MACE, which included cardiac death, stroke, nonfatal MI, new hospitalization due to heart failure, or target vessel revascularization, the rates were lower in the colchicine group at 1 month (4.3% vs. 7.5%) and 1 year (9.3% vs. 11.2%), but neither approached significance.

For ST-segment resolution, the proportions were generally comparable among the colchicine and placebo groups, respectively, for the proportion below 50% (18.6% vs. 23.1%), between 50% and 70% (16.8% vs. 15.6%), and above 70% (64.6% vs. 61.3%).

The average troponin levels were nonsignificantly lower at 6 hours (1,847 vs. 2,883 ng/mL) in the colchicine group but higher at 48 hours (1,197 vs. 1,147 ng/mL). The average C-reactive protein (CRP) levels at 48 hours were nonsignificantly lower on colchicine (176.5 vs. 244.5 mg/L).

There were no significant differences in postprocedural perfusion, as measured with TIMI blood flow, or in the rate of stent thrombosis, which occurred in roughly 3% of each group of patients.

The small sample size was one limitation of this study, Dr. Jenab acknowledged. For this and other reasons, he cautioned that these data are not definitive and do not preclude a benefit on clinical outcomes in a study with a larger size, a different design, or different dosing.
 

 

 

Timing might be the issue

However, even if colchicine has a potential benefit in this setting, timing might be a major obstacle, according to Binata Shah, MD, associate director of research for the Cardiac Catheterization Laboratory at New York University.

Dr. Binita Shah

“We have learned from our rheumatology colleagues that peak plasma levels of colchicine are not achieved for at least 1 hour after the full loading dose,” Dr. Shah said. “With us moving so quickly in a primary PCI setting, it is hard to imagine that colchicine would have had time to really kick in and exert its anti-inflammatory effect.”

Indeed, the problem might be worse than reaching the peak plasma level.

“Even though peak plasma levels occur as early as 1 hour after a full loading dose, we see that it takes about 24 hours to really see the effects translate downstream into more systemic inflammatory markers such as CRP and interleukin-6,” she added. If lowering these signals of inflammation is predictive of benefit, than this might be the biggest obstacle to benefit from colchicine in an urgent treatment setting.

Dr. Jenab and Dr. Shah reported no potential conflicts of interest.

‘Major update’ of BP guidance for kidney disease; treat to 120 mm Hg

Article Type
Changed

The new 2021 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline for blood pressure management for adults with chronic kidney disease (CKD) who are not receiving dialysis advises treating to a target systolic blood pressure of less than 120 mm Hg, provided measurements are “standardized” and that blood pressure is “measured properly.”

This blood pressure target – largely based on evidence from the Systolic Blood Pressure Intervention Trial (SPRINT) – represents “a major update” from the 2012 KDIGO guideline, which advised clinicians to treat to a target blood pressure of less than or equal to 130/80 mm Hg for patients with albuminuria or less than or equal to 140/90 mm Hg for patients without albuminuria.

The new goal is also lower than the less than 130/80 mm Hg target in the 2017 American College of Cardiology/American Heart Association guideline.

In a study of the public health implications of the guideline, Kathryn Foti, PhD, and colleagues determined that 70% of U.S. adults with CKD would now be eligible for treatment to lower blood pressure, as opposed to 50% under the previous KDIGO guideline and 56% under the ACC/AHA guideline.

“This is a major update of an influential set of guidelines for chronic kidney disease patients” at a time when blood pressure control is worsening in the United States, Dr. Foti, a postdoctoral researcher in the department of epidemiology at Johns Hopkins Bloomberg School of Public Health, Baltimore, said in a statement from her institution.

The 2021 KDIGO blood pressure guideline and executive summary and the public health implications study are published online in Kidney International.
 

First, ‘take blood pressure well’

The cochair of the new KDIGO guidelines, Alfred K. Cheung, MD, from the University of Utah, Salt Lake City, said in an interview that the guideline has “two important points.”

First, “take that blood pressure well,” he said. “That has a lot to do with patient preparation rather than any fancy instrument,” he emphasized.

Second, the guideline proposes a systolic blood pressure target of less than 120 mm Hg for most people with CKD not receiving dialysis, except for children and kidney transplant recipients. This target is “contingent on ‘standardized’ blood pressure measurement.”

The document provides a checklist for obtaining a standardized blood pressure measurement, adapted from the 2017 ACC/AHA blood pressure guidelines. It starts with the patient relaxed and sitting on a chair for more than 5 minutes.

In contrast to this measurement, a “routine” or “casual” office blood pressure measurement could be off by plus or minus 10 mm Hg, Dr. Cheung noted.

In a typical scenario, he continued, a patient cannot find a place to park, rushes into the clinic, and has his or her blood pressure checked right away, which would provide a “totally unreliable” reading. Adding a “fudge factor” (correction factor) would not provide an accurate reading.

Clinicians “would not settle for a potassium measurement that is 5.0 mmol/L plus or minus a few decimal points” to guide treatment, he pointed out.
 

Second, target 120, properly measured

“The very first chapter of the guidelines is devoted to blood pressure measurement, because we recognize if we’re going to do 120 [mm Hg] – the emphasis is on 120 measured properly – so we try to drive that point home,” Tara I. Chang, MD, guideline second author and a coauthor of the public health implications study, pointed out in an interview.

“There are a lot of other things that we base clinical decisions on where we really require some degree of precision, and blood pressure is important enough that to us it’s kind of in the same boat,” said Dr. Chang, from Stanford (Calif.) University.

“In SPRINT, people were randomized to less than less than 120 vs. less than 140 (they weren’t randomized to <130),” she noted.

“The recommendation should be widely adopted in clinical practice,” the guideline authors write, “since accurate measurements will ensure that proper guidance is being applied to the management of BP, as it is to the management of other risk factors.”
 

Still need individual treatment

Nevertheless, patients still need individualized treatment, the document stresses. “Not every patient with CKD will be appropriate to target to less than 120,” Dr. Chang said. However, “we want people to at least consider less than 120,” she added, to avoid therapeutic inertia.

“If you take the blood pressure in a standardized manner – such as in the ACCORD trial and in the SPRINT trial – even patients over 75 years old, or people over 80 years old, they have very little side effects,” Dr. Cheung noted.

“In the overall cohort,” he continued, “they do not have a significant increase in serious adverse events, do not have adverse events of postural hypotension, syncope, bradycardia, injurious falls – so people are worried about it, but it’s not borne out by the data.

“That said, I have two cautions,” Dr. Cheung noted. “One. If you drop somebody’s blood pressure rapidly over a week, you may be more likely to get in trouble. If you drop the blood pressure gradually over several weeks, several months, you’re much less likely to get into trouble.”

“Two. If the patient is old, you know the patient has carotid stenosis and already has postural dizziness, you may not want to try on that patient – but just because the patient is old is not the reason not to target 120.”
 

ACE inhibitors and ARBs beneficial in albuminuria, underused

“How do you get to less than 120? The short answer is, use whatever medications you need to – there is no necessarily right cocktail,” Dr. Chang said.

“We’ve known that angiotensin-converting enzyme (ACE) inhibitors and ARBs [angiotensin II receptor blockers] are beneficial in patients with CKD and in particular those with heavier albuminuria,” she continued. “We’ve known this for over 20 years.”

Yet, the study identified underutilization – “a persistent gap, just like blood pressure control and awareness,” she noted. “We’re just not making much headway.

“We are not recommending ACE inhibitors or ARBs for all the patients,” Dr. Cheung clarified. “If you are diabetic and have heavy proteinuria, that’s when the use of ACE inhibitors and ARBs are most indicated.”
 

Public health implications

SPRINT showed that treating to a systolic blood pressure of less than 120 mm Hg vs. less than 140 mm Hg reduced the risk for cardiovascular disease by 25% and all-cause mortality by 27% for participants with and those without CKD, Dr. Foti and colleagues stress.

They aimed to estimate how the new guideline would affect (1) the number of U.S. patients with CKD who would be eligible for blood pressure lowering treatment, and (2) the proportion of those with albuminuria who would be eligible for an ACE inhibitor or an ARB.

The researchers analyzed data from 1,699 adults with CKD (estimated glomerular filtration rate, 15-59 mL/min/1.73 m2 or a urinary albumin-to-creatinine ratio of ≥30 mg/g) who participated in the 2015-2018 National Health and Nutrition Examination Survey.

Both the 2021 and 2012 KDIGO guidelines recommend that patients with albuminuria and blood pressure higher than the target value who are not kidney transplant recipients should be treated with an ACE inhibitor or an ARB.

On the basis of the new target, 78% of patients with CKD and albuminuria were eligible for ACE inhibitor/ARB treatment by the 2021 KDIGO guideline, compared with 71% by the 2012 KDIGO guideline. However, only 39% were taking one of these drugs.

These findings show that “with the new guideline and with the lower blood pressure target, you potentially have an even larger pool of people who have blood pressure that’s not under control, and a potential larger group of people who may benefit from ACE inhibitors and ARBs,” Dr. Chang said.

“Our paper is not the only one to show that we haven’t made a whole lot of progress,” she said, “and now that the bar has been lowered, there [have] to be some renewed efforts on controlling blood pressure, because we know that blood pressure control is such an important risk factor for cardiovascular outcomes.”

Target-lesion failure reduced 2 years after MI with biodegradable stent

Article Type
Changed

 

For a primary composite target-lesion failure outcome, a biodegradable polymer sirolimus-eluting stent showed superiority at 2 years over a durable polymer everolimus-eluting stent in patients undergoing percutaneous intervention (PCI) for an ST-segment elevated acute myocardial infarction (STEMI), according to a late-breaking trial presentation at CRT 2021.

As in the previously reported 1-year results from the BIOSTEMI trial, the advantage of the biodegradable device was “driven by lower rates of target-lesion revascularization,” reported Thomas Pilgrim, MD, of the University of Bern (Switzerland).

Drug-eluting stents have already been established as superior to bare-metal stents, but the question asked in this study is whether the polymer that carries antiproliferative drugs, such as sirolimus or everolimus, improves lesion-based outcomes if it is biodegradable rather than durable, Dr. Pilgrim explained.

The composite primary outcome was target-lesion failure defined by cardiac death, target-lesion MI, or clinically indicated target-lesion revascularization.

After 2 years of follow-up, the rates of target-lesion failure were 5.1% and 8.1% for the biodegradable and durable polymer stents, respectively. This 0.58 rate ratio was statistically significant, favoring the biodegradable stent.

The investigator-initiated BIOSTEMI trial randomized 1,300 patients to one of two drug-eluting stents with ultrathin struts. One was the Orsiro stent that employs a biodegradable polymer to deliver sirolimus. The other was the Xience Prime/Xpedition that uses a durable polymer stent to deliver everolimus.

The strut thicknesses of the Orsiro stent are 60 mcm for stents of 3.0 mm in diameter or smaller and 80 mcm for those with a larger diameter. The strut thickness of the Xience stent is 81 mcm regardless of diameter.

“Patients with an acute myocardial infarction are at increased risk of stent-related events due to exacerbated inflammatory response and delayed arterial healing,” Dr. Pilgrim said. The theoretical advantages of polymer that biodegrades include “mitigation of the arterial injury, facilitation of endothelialization, and reduced intimal hyperplasia,” he explained at the meeting sponsored by MedStar Heart & Vascular Institute.

The rates of cardiac death (2.9% vs. 3.2%) and target-vessel MI (2.9% vs. 3.2%) were lower for the biodegradable polymer stent, but not significantly. However, the rates of target-vessel revascularization at 2 years were 2.5% versus 5.1%. The associated rate ratio of 0.52 favoring the biodegradable stent was significant.

Similar results favoring the biodegradable polymer stent were observed at 1 year, but those earlier results factored in historical data from the BIOSCIENCE trial, using a Bayesian analysis, to improve the power of the comparison. In this 2-year analysis, the superiority of the biodegradable polymer stent to the durable polymer stent remained statistically significant even when excluding those historical controls.

The advantage of the biodegradable polymer stent was confined to “device-oriented” outcomes, according to Dr. Pilgrim. When compared for important patient-oriented outcomes at 2 years, there were no significant differences. Rather, several were numerically more common, including death (4.2% vs. 3.8%) and MI (3.7% vs. 3.1%) in those who were randomized to the biodegradable polymer stent.

But these types of clinical outcomes are not necessarily related to stent assignment because “up to one-half of all events over the 2 years of follow-up were unrelated to the stent implanted,” Dr. Pilgrim said. He noted that high rates of events unrelated to the implanted stent have also been seen in follow-up of other comparative stent trials.

The superiority of the biodegradable stent is noteworthy. Although Dr. Pilgrim described the BIOSTEMI trial as “the first head-to-head comparison of two new-generation drug-eluting stents in patients undergoing a primary percutaneous intervention for acute myocardial infarction,” there have been several studies comparing stents for other indications. Significant differences have been uncommon.

“Over the last 10 years, we have seen a number of noninferiority stent trials, but only now are we seeing some superiority differences. This is a move in the right direction,” commented Sripal Bangalore, MD, director of the cardiovascular outcomes group, New York University.

However, he, like others, questioned whether the difference in outcomes in this trial could be fully attributed to the type of polymer. He noted that all stents could be characterized by multiple small and large differences in design and composition. Any specific characteristic, such as biodegradable polymer, might be an important contributor but not an isolated factor in the outcomes observed.

On the day that the 2-year results of the BIOSTEMI trial were presented at the CRT 2021 meeting they were simultaneously published in JACC: Cardiovascular Interventions.

For a primary composite target-lesion failure outcome, a biodegradable polymer sirolimus-eluting stent showed superiority at 2 years over a durable polymer everolimus-eluting stent in patients undergoing percutaneous intervention (PCI) for an ST-segment elevated acute myocardial infarction (STEMI), according to a late-breaking trial presentation at CRT 2021.

As in the previously reported 1-year results from the BIOSTEMI trial, the advantage of the biodegradable device was “driven by lower rates of target-lesion revascularization,” reported Thomas Pilgrim, MD, of the University of Bern (Switzerland).

Drug-eluting stents have already been established as superior to bare-metal stents, but the question asked in this study is whether the polymer that carries antiproliferative drugs, such as sirolimus or everolimus, improves lesion-based outcomes if it is biodegradable rather than durable, Dr. Pilgrim explained.

The composite primary outcome was target-lesion failure defined by cardiac death, target-lesion MI, or clinically indicated target-lesion revascularization.

After 2 years of follow-up, the rates of target-lesion failure were 5.1% and 8.1% for the biodegradable and durable polymer stents, respectively. This 0.58 rate ratio was statistically significant, favoring the biodegradable stent.

Eating fish tied to fewer CVD events in high-risk people

Article Type
Changed

 

People with cardiovascular disease who regularly ate fish had significantly fewer major CVD events and there were fewer total deaths, compared with similar individuals who didn’t eat fish, but there was no beneficial link from eating fish among the general population in prospective data collected from more than 191,000 people from 58 countries.

Despite the neutral finding among people without CVD, the finding that eating fish was associated with significant benefit for those with CVD or who were at high risk for CVD confirms the public health importance of regular fish or fish oil consumption, said one expert.

A little over a quarter of those included in the new study had a history of CVD or were at high risk for CVD. In this subgroup of more than 51,000 people, those who consumed on average at least two servings of fish weekly (at least 175 g, or about 6.2 ounces per week) had a significant 16% lower rate of major CVD events during a median follow-up of about 7.5 years.

The rate of all-cause death was a significant 18% lower among people who ate two or more fish portions weekly, compared with those who didn’t, Deepa Mohan, PhD, and associates wrote in their report in JAMA Internal Medicine.

The researchers saw no additional benefit when people regularly ate greater amounts of fish.

“There is a significant protective benefit of fish consumption in people with cardiovascular disease,” said Andrew Mente, PhD, a senior investigator on the study and an epidemiologist at McMaster University, Hamilton, Ont..

“This study has important implications for guidelines on fish intake globally. It indicates that increasing fish consumption and particularly oily fish in vascular patients may produce a modest cardiovascular benefit,” he said in a statement released by McMaster.
 

‘A large body of evidence’ for CVD benefit

The neutral finding of no significant benefit (as well as no harm) regarding either CVD events or total mortality among people without CVD “does not alter the large body of prior observational evidence supporting the cardiac benefits of fish intake in general populations,” noted Dariush Mozaffarian, MD, DrPH, in a commentary that accompanies the report by Dr. Mohan and colleagues.

Although the new analysis failed to show a significant association between regular fish consumption and fewer CVD events for people without established CVD or CVD risk, “based on the cumulative evidence from prospective observational studies, randomized clinical trials, and mechanistic and experimental studies, modest fish consumption appears to have some cardiac benefits,” he added.

“Adults should aim to consume about two servings of fish per week, and larger benefits may accrue from nonfried oily (dark meat) fish,” wrote Dr. Mozaffarian, a professor of medicine and nutrition at Tufts University, Boston.

Oily, dark fishes include salmon, tuna steak, mackerel, herring, and sardines. Species such as these contain the highest levels of long-chain omega-3 fatty acids, eicosapentaenoic acid, and docosapentaenoic acid; these nutrients likely underlie the CVD benefits from fish, Dr. Mozaffarian said in an interview with JAMA Internal Medicine that accompanied his commentary. (Dr. Mente also participated.)

Fish oil lowers heart rate, blood pressure, and triglycerides (at high dosages), increases adiponectin, improves endothelial function, and in some studies improves oxygen consumption in myocardium. If there is benefit from fish it’s from the omega 3s, and all in all the evidence supports this,” but because the evidence is primarily observational, it can only show linkage and cannot prove causation, he explained.

Given the potential benefit and limited risk, “I think everyone should aim to eat two servings of fish each week, preferentially oily fish. That’s very solid,” said Dr. Mozaffarian, who is also a cardiologist and dean of the Tufts Friedman School of Nutrition Science.

The investigators did not have adequate data to compare the associations between outcomes and a diet with oily fish versus less oily fish.
 

 

 

OTC fish oil capsules are ‘very reasonable’

For people who either can’t consume two fish meals a week or want to ensure their omega 3 intake is adequate, “it’s very reasonable for the average person to take one OTC [over-the-counter] fish oil capsule a day,” Dr. Mozaffarian added.

He acknowledged that several studies of fish oil supplements failed to show benefit, but several others have. “It’s a confusing field, but the evidence supports benefit from omega 3s,” he concluded.

He discounted the new finding that only people with established CVD or who are at high-risk benefit. “I’m not sure we should make too much of this, because many prior studies showed a lower CVD risk in fish-eating people without prevalent CVD,” he said. The new study “provides important information given its worldwide breadth.”

The new report used data regarding 191,558 people enrolled prospectively in any of four studies. The average age of the participants was 54 years, and 52% were women.

During follow-up, death from any cause occurred in 6% of those without CVD or CVD risk and in 13% of those with these factors. Major CVD events occurred in 5% and 17% of these two subgroups, respectively. To calculate the relative risks between those who ate fish and those who did not, the investigators used standard multivariate adjustment for potential confounders and adjusted for several dietary variables, Dr. Mente said.

Dr. Mohan and Dr. Mente disclosed no relevant financial relationships. Dr. Mozaffarian has received personal fees from Acasti Pharma, Amarin, America’s Test Kitchen, Barilla, Danone, GEOD, and Motif Food Works, and he has been an adviser to numerous companies.

Inpatient sodium imbalances linked to adverse COVID-19 outcomes

Article Type
Changed

 

Both high and low serum sodium levels are associated with adverse outcomes for hospitalized patients with COVID-19, new research suggests.

In the retrospective study of 488 patients hospitalized with COVID-19 at one of two London hospitals between February and May 2020, hypernatremia (defined as serum sodium level >145 mmol/L) at any time point during hospital stay was associated with a threefold increase in inpatient mortality.

Hyponatremia (serum sodium level <135 mmol/L) was associated with twice the likelihood of requiring advanced ventilatory support. In-hospital mortality was also increased among patients with hypovolemic hyponatremia.

“Serum sodium values could be used in clinical practice to identify patients with COVID-19 at high risk of poor outcomes who would benefit from more intensive monitoring and judicious rehydration,” Ploutarchos Tzoulis, MD, PhD, and colleagues wrote in their article, which was published online on Feb. 24, 2021, in the Journal of Clinical Endocrinology and Metabolism.

The findings will be presented at the upcoming news conference held by the Endocrine Society
 

Should sodium be included in a risk calculator for COVID-19?

Dr. Tzoulis, professor of endocrinology at the University College London Medical School, said in an interview that “sodium could be incorporated in risk calculators across other routine biomarkers, such as white cell count, lymphocytes, and CRP [C-reactive protein], in order to provide a tool for dynamic risk stratification throughout the clinical course of COVID-19 and assist clinical decision-making.”

Moreover, he said, “we should follow less conservative strategies in the rate and amount of fluid resuscitation in order to prevent hypernatremia, which is induced by negative fluid balance and can often be iatrogenic.”

Dr. Steven Q. Simpson

Asked to comment, Steven Q. Simpson, MD, professor of medicine in the division of pulmonary, critical care, and sleep medicine at the University of Kansas, Kansas City, said that the article is missing key results that would assist in interpreting of the findings.

“Data regarding diuretic use and sparing of fluid administration are not in the paper. ... It is simply not possible to tell whether serum sodium is a ‘predictor’ ... or if it is a side effect of other issues or actions taken by physicians in patients who are progressing poorly.

“To say that sodium needs to be included in a risk calculator is to subtly suggest that there is some causal association with mortality, and that has quite clearly not been established,” stressed Dr. Simpson, who is president of the American College of Chest Physicians but was not speaking for the organization.

He added: “The data are interesting, but not actionable. It is common practice in critical care medicine to adjust water and salt intake to maintain serum sodium within the normal range, so the paper really doesn’t change any behavior.”

Dr. Tzoulis said in an interview that, despite not having electronic medical record data on diuretic use or fluid input and output, “our acute physicians and intensivists at both study sites have been adamant that they’ve not routinely used diuretics in COVID-19 patients. Diuretics have been sparingly used in our cohort, and also the frequency of pulmonary edema was reported as below 5%.”

Regarding volume of fluid intake, Dr. Tzoulis noted, “At our hospital sites, the strategy has been that of cautious fluid resuscitation. In fact, the amount of fluid given has been reported by our physicians and intensivists as ‘on purpose much more conservative than the usual one adopted in patients with community-acquired pneumonia at risk of respiratory failure.’ ”
 

 

 

Hyper- and hyponatremia linked to adverse COVID-19 outcomes

In the study, 5.3% of the 488 patients had hypernatremia at hospital presentation, and 24.6% had hyponatremia. Of note, only 19% of those with hyponatremia underwent laboratory workup to determine the etiology. Of those, three quarters had hypovolemic hyponatremia, determined on the basis of a urinary sodium cutoff of 30 mmol/L.

The total in-hospital mortality rate was 31.1%. There was a strong, although nonsignificant, trend toward higher mortality in association with sodium status at admission. Death rates were 28.4%, 30.8%, and 46.1% for those who were normonatremic, hyponatremic, and hypernatremic, respectively (P = .07). Baseline serum sodium levels didn’t differ between survivors (137 mmol/L) and nonsurvivors (138 mmol/L).

In multivariable analysis, the occurrence of hypernatremia at any point during the first 5 days in the hospital was among three independent risk factors for higher in-hospital mortality (adjusted hazard ratio, 2.74; P = .02). The other risk factors were older age and higher CRP level.

Overall, hyponatremia was not associated with death (P = .41).

During hospitalization, 37.9% of patients remained normonatremic; 36.9% experienced hyponatremia; 10.9% had hypernatremia; and 14.3% had both conditions at some point during their stay.

In-hospital mortality was 21% among those with normonatremia, compared with 56.6% for those with hypernatremia (odds ratio, 3.05; P = .0038) and 45.7% for those with both (OR, 2.25; P < .0001).

The 28.3% mortality rate in the overall group that experienced hyponatremia didn’t differ significantly from the 21.1% in the normonatremic group (OR, 1.34; P = .16). However, the death rate was 40.9% among the subgroup that developed hypovolemic hyponatremia, significantly higher than the normonatremic group (OR, 2.59, P = .0017).

The incidence of hyponatremia decreased from 24.6% at admission to 14.1% 5 days later, whereas the frequency of hypernatremia rose from 5.3% to 13.8%.
 

Key finding: Link between hospital-acquired hypernatremia and death

“The key novel finding of our study was that hospital-acquired hypernatremia, rather than hypernatremia at admission, was a predictor for in-hospital mortality, with the worst prognosis being reported in patients with the largest increase in serum sodium in the first 5 days of hospitalization,” noted Dr. Tzoulis and colleagues.

Hypernatremia was present in 29.6% of nonsurvivors, compared with 5.2% in survivors.

Among 120 patients with hyponatremia at admission, 31.7% received advanced respiratory support, compared with 17.5% and 7.7% of those with normonatremia or hypernatremia, respectively (OR, 2.18; P = .0011).

In contrast, there was no difference in the proportions needing ventilatory support between those with hypernatremia and those with normonatremia (16.7% vs. 12.4%; OR, 1.44; P = .39).

Acute kidney injury occurred in 181 patients (37.1%). It was not related to serum sodium concentration at any time point.

Dr. Tzoulis and Dr. Simpson disclosed no relevant financial relationships.

Both high and low serum sodium levels are associated with adverse outcomes for hospitalized patients with COVID-19, new research suggests.

In the retrospective study of 488 patients hospitalized with COVID-19 at one of two London hospitals between February and May 2020, hypernatremia (defined as serum sodium level >145 mmol/L) at any time point during hospital stay was associated with a threefold increase in inpatient mortality.

Hyponatremia (serum sodium level <135 mmol/L) was associated with twice the likelihood of requiring advanced ventilatory support. In-hospital mortality was also increased among patients with hypovolemic hyponatremia.

“Serum sodium values could be used in clinical practice to identify patients with COVID-19 at high risk of poor outcomes who would benefit from more intensive monitoring and judicious rehydration,” Ploutarchos Tzoulis, MD, PhD, and colleagues wrote in their article, which was published online on Feb. 24, 2021, in the Journal of Clinical Endocrinology and Metabolism.

The findings will be presented at the upcoming news conference held by the Endocrine Society
 

Should sodium be included in a risk calculator for COVID-19?

Dr. Tzoulis, professor of endocrinology at the University College London Medical School, said in an interview that “sodium could be incorporated in risk calculators across other routine biomarkers, such as white cell count, lymphocytes, and CRP [C-reactive protein], in order to provide a tool for dynamic risk stratification throughout the clinical course of COVID-19 and assist clinical decision-making.”

Moreover, he said, “we should follow less conservative strategies in the rate and amount of fluid resuscitation in order to prevent hypernatremia, which is induced by negative fluid balance and can often be iatrogenic.”

Dr. Steven Q. Simpson

Asked to comment, Steven Q. Simpson, MD, professor of medicine in the division of pulmonary, critical care, and sleep medicine at the University of Kansas, Kansas City, said that the article is missing key results that would assist in interpreting of the findings.

“Data regarding diuretic use and sparing of fluid administration are not in the paper. ... It is simply not possible to tell whether serum sodium is a ‘predictor’ ... or if it is a side effect of other issues or actions taken by physicians in patients who are progressing poorly.

“To say that sodium needs to be included in a risk calculator is to subtly suggest that there is some causal association with mortality, and that has quite clearly not been established,” stressed Dr. Simpson, who is president of the American College of Chest Physicians but was not speaking for the organization.

He added: “The data are interesting, but not actionable. It is common practice in critical care medicine to adjust water and salt intake to maintain serum sodium within the normal range, so the paper really doesn’t change any behavior.”

Dr. Tzoulis said in an interview that, despite not having electronic medical record data on diuretic use or fluid input and output, “our acute physicians and intensivists at both study sites have been adamant that they’ve not routinely used diuretics in COVID-19 patients. Diuretics have been sparingly used in our cohort, and also the frequency of pulmonary edema was reported as below 5%.”

Regarding volume of fluid intake, Dr. Tzoulis noted, “At our hospital sites, the strategy has been that of cautious fluid resuscitation. In fact, the amount of fluid given has been reported by our physicians and intensivists as ‘on purpose much more conservative than the usual one adopted in patients with community-acquired pneumonia at risk of respiratory failure.’ ”

Obesity: A ‘double hit’ in pregnant women with heart disease

Article Type
Changed

 

Being obese and pregnant raises the risk for cardiac complications in women with preexisting heart disease, new research suggests, highlighting the need for earlier interventions in this high-risk population.

The analysis of 790 pregnancies revealed that 23% of women with obesity, defined as body mass index greater than 30 kg/m2, had a cardiac event during pregnancy versus 14% of women with normal body weight (P = .006).

The difference was driven largely by an increase in heart failure (8% vs. 3%; P = .02), although arrhythmias also trended higher in obese women (14% vs. 10%; P = .19).

Nearly half of the women with obesity and a cardiac event presented in the postpartum period (47%).

In multivariate analysis, both obesity and Canadian Cardiac Disease in Pregnancy Study (CARPREG) II risk score were independent predictors of cardiac events (odds ratios for both, 1.7), the investigators, led by Birgit Pfaller, MD, University of Toronto, reported in the Journal of the American College of Cardiology.

Although obesity has been linked to worse pregnancy outcomes and higher cardiovascular risk after delivery in the general population, the authors noted that this is the first study to examine its effect on outcomes in women with heart disease.

“We wanted to look at this high-risk group of women that had preexisting heart disease, but in addition had obesity, to try and find out if there was a kind of double hit for these women – and that, in the end, is what we found. It’s not just simply having heart disease, not simply having obesity, but the combination that’s problematic,” senior author and cardiologist Candice Silversides, MD, University of Toronto, said in an interview.

The findings are concerning given the rising prevalence of obesity worldwide. National data from 2018 show that slightly more than half of women who gave birth in the United States were significantly overweight or obese before becoming pregnant.

Similarly, in the present analysis of 600 women in the CARPREG study who gave birth from 2004 to 2014, nearly 1 in 5 pregnancies (19%) occurred in women with obesity and 25% were in overweight women.

Obese women were significantly more likely than those without obesity to have coronary artery disease (6% vs. 2%), cardiomyopathies (19% vs. 8%) and left ventricular dysfunction (19% vs. 12%) and to be hypertensive or have a hypertensive disorder of pregnancy (13% vs. 3%).

Preeclampsia developed in 32 women during the index pregnancy and 69% of these women were obese or overweight. Cardiac event rates were similar in women with or without preeclampsia but trended higher in women with preeclampsia with versus without obesity (36% vs. 14%; P = .20).

The ill effects of obesity were also reflected in fetal and neonatal events. Overall, 43% of women with obesity and 33% of normal-weight women had at least one fetal event (P = .02), with higher rates of preterm birth (19% vs. 10%; P = .005) and respiratory distress syndrome (8% vs. 3%; P = .02) in women with obesity. Congenital cardiac malformations were present in 6% of women in both groups.

Taken together, the composite of cardiac events, preeclampsia, or fetal events was significantly more common in women with obesity than in normal-weight women (56% vs. 41%; P = .002).

“We’ve spent the last number of years trying to research and understand what the drivers of these adverse outcomes are in this high-risk pregnant cohort, but on a bigger picture the real issue is how do we start intervening in a meaningful way,” Dr. Silversides said.

Like many in the burgeoning field of cardio-obstetrics, the team proposed a multidisciplinary approach that stresses preconception counseling, educating pregnant women with heart disease and obesity about their risks, ensuring that dietary advice, weight-gain recommendations, and comorbidities are addressed as part of routine care, and providing postpartum surveillance.

Preconception screening “has been the recommendation for a long, long time; it’s just that it doesn’t always happen in reality,” she said. “Many pregnancies aren’t planned and not all women are filtered into preconception counseling. So sometimes you’ll do it at the first antenatal visit and try to ensure women are educated but optimally you want to do it well in advance of pregnancy.”

Part of that preconception counseling “should also include giving them appropriate advice for contraception, if what they want to do is avoid pregnancy,” added Dr. Silversides.

Garima Sharma, MD, Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University, Baltimore, and colleagues wrote in an accompanying editorial that the adverse events observed in this high-risk cohort have “important implications for cardio-obstetricians and should be incorporated in routine prepregnancy and antenatal counseling, monitoring, and risk stratification for women with existing cardiovascular disease.”

They pointed to a paucity of data incorporating maternal prepregnancy obesity and gestational weight gain in risk prediction and called for larger population-based studies on the additive impact of obesity severity on predicting adverse cardiac events in women with existing cardiovascular disease.

Randomized trials are also urgently needed to evaluate the effect of nutritional and behavioral interventions in pregnancy on short- and long-term outcomes in mother and child.

“As the obesity epidemic continues to grow and public health interventions promoting lifestyle changes for obesity management remain a major challenge, maternal obesity may prove to be the ‘Achilles’ heel’ of sustainable national efforts to reduce maternal mortality and improve health equity. This is a call to action,” Dr. Sharma and colleagues concluded.

The investigators noted that the study was conducted at a single center and used self-reported pregnancy weight collected at the first antenatal visit, which may have underestimated obesity rates. Other limitations are that weight changes over the course of pregnancy were not studied and there was a limited number of women with a body mass index of 40 or higher.

The study was supported by a grant from the Allan E. Tiffin Trust, Toronto General and Western Hospital Foundation, and by a donation from Mrs. Josephine Rogers, Toronto General Hospital. Dr. Silversides is supported by the Miles Nadal Chair in Pregnancy and Heart Disease. Dr. Sharma and colleagues disclosed no relevant financial relationships.

Preeclampsia developed in 32 women during the index pregnancy and 69% of these women were obese or overweight. Cardiac event rates were similar in women with or without preeclampsia but trended higher in women with preeclampsia with versus without obesity (36% vs. 14%; P = .20).

The ill effects of obesity were also reflected in fetal and neonatal events. Overall, 43% of women with obesity and 33% of normal-weight women had at least one fetal event (P = .02), with higher rates of preterm birth (19% vs. 10%; P = .005) and respiratory distress syndrome (8% vs. 3%; P = .02) in women with obesity. Congenital cardiac malformations were present in 6% of women in both groups.

Taken together, the composite of cardiac events, preeclampsia, or fetal events was significantly more common in women with obesity than in normal-weight women (56% vs. 41%; P = .002).

“We’ve spent the last number of years trying to research and understand what the drivers of these adverse outcomes are in this high-risk pregnant cohort, but on a bigger picture the real issue is how do we start intervening in a meaningful way,” Dr. Silversides said.

Like many in the burgeoning field of cardio-obstetrics, the team proposed a multidisciplinary approach that stresses preconception counseling, educating pregnant women with heart disease and obesity about their risks, ensuring that dietary advice, weight-gain recommendations, and comorbidities are addressed as part of routine care, and providing postpartum surveillance.

Preconception screening “has been the recommendation for a long, long time; it’s just that it doesn’t always happen in reality,” she said. “Many pregnancies aren’t planned and not all women are filtered into preconception counseling. So sometimes you’ll do it at the first antenatal visit and try to ensure women are educated but optimally you want to do it well in advance of pregnancy.”

Part of that preconception counseling “should also include giving them appropriate advice for contraception, if what they want to do is avoid pregnancy,” added Dr. Silversides.

Garima Sharma, MD, Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University, Baltimore, and colleagues wrote in an accompanying editorial that the adverse events observed in this high-risk cohort have “important implications for cardio-obstetricians and should be incorporated in routine prepregnancy and antenatal counseling, monitoring, and risk stratification for women with existing cardiovascular disease.”

They pointed to a paucity of data incorporating maternal prepregnancy obesity and gestational weight gain in risk prediction and called for larger population-based studies on the additive impact of obesity severity on predicting adverse cardiac events in women with existing cardiovascular disease.

Randomized trials are also urgently needed to evaluate the effect of nutritional and behavioral interventions in pregnancy on short- and long-term outcomes in mother and child.

“As the obesity epidemic continues to grow and public health interventions promoting lifestyle changes for obesity management remain a major challenge, maternal obesity may prove to be the ‘Achilles’ heel’ of sustainable national efforts to reduce maternal mortality and improve health equity. This is a call to action,” Dr. Sharma and colleagues concluded.

The investigators noted that the study was conducted at a single center and used self-reported pregnancy weight collected at the first antenatal visit, which may have underestimated obesity rates. Other limitations are that weight changes over the course of pregnancy were not studied and there was a limited number of women with a body mass index of 40 or higher.

The study was supported by a grant from the Allan E. Tiffin Trust, Toronto General and Western Hospital Foundation, and by a donation from Mrs. Josephine Rogers, Toronto General Hospital. Dr. Silversides is supported by the Miles Nadal Chair in Pregnancy and Heart Disease. Dr. Sharma and colleagues disclosed no relevant financial relationships.

CDC data strengthen link between obesity and severe COVID

Article Type
Changed

 

Officials have previously linked being overweight or obese to a greater risk for more severe COVID-19. A report today from the U.S. Centers for Disease Control and Prevention adds numbers and some nuance to the association.

Data from nearly 150,000 U.S. adults hospitalized with COVID-19 nationwide indicate that risk for more severe disease outcomes increases along with body mass index (BMI). The risk of COVID-19–related hospitalization and death associated with obesity was particularly high among people younger than 65.

“As clinicians develop care plans for COVID-19 patients, they should consider the risk for severe outcomes in patients with higher BMIs, especially for those with severe obesity,” the researchers note. They add that their findings suggest “progressively intensive management of COVID-19 might be needed for patients with more severe obesity.”

People with COVID-19 close to the border between a healthy and overweight BMI – from 23.7 kg/m2 to 25.9 kg/m2 – had the lowest risks for adverse outcomes.

The study was published online today in Morbidity and Mortality Weekly Report.
 

Greater need for critical care

The risk of ICU admission was particularly associated with severe obesity. For example, those with a BMI in the 40-44.9 kg/m2 category had a 6% increased risk, which jumped to 16% higher among those with a BMI of 45 or greater.

Compared to people with a healthy BMI, the need for invasive mechanical ventilation was 12% more likely among overweight adults with a BMI of 25-29.2. The risked jumped to 108% greater among the most obese people, those with a BMI of 45 or greater, lead CDC researcher Lyudmyla Kompaniyets, PhD, and colleagues reported.

Moreover, the risks for hospitalization and death increased in a dose-response relationship with obesity.

For example, risks of being hospitalized were 7% greater for adults with a BMI between 30 and 34.9 and climbed to 33% greater for those with a BMI of 45. Risks were calculated as adjusted relative risks compared with people with a healthy BMI between 18.5 and 24.9.

Interestingly, being underweight was associated with elevated risk for COVID-19 hospitalization as well. For example, people with a BMI of less than 18.5 had a 20% greater chance of admission vs. people in the healthy BMI range. Unknown underlying medical conditions or issues related to nutrition or immune function could be contributing factors, the researchers note.
 

Elevated risk of dying

The risk of death in adults with obesity ranged from 8% higher in the 30-34.9 range up to 61% greater for those with a BMI of 45.

Chronic inflammation or impaired lung function from excess weight are possible reasons that higher BMI imparts greater risk, the researchers note.

The CDC researchers evaluated 148,494 adults from 238 hospitals participating in PHD-SR database. Because the study was limited to people hospitalized with COVID-19, the findings may not apply to all adults with COVID-19.

Another potential limitation is that investigators were unable to calculate BMI for all patients in the database because about 28% of participating hospitals did not report height and weight.

The study authors had no relevant financial relationships to disclose.

Missed visits during pandemic cause ‘detrimental ripple effects’

Article Type
Changed

 

More than one-third of adults aged 18-64 years in the United States delayed or went without medical care because of efforts by patients or providers to reduce the spread of COVID-19, according to a new report from the Urban Institute.

Among the adults who postponed or missed care, 32.6% said the gap worsened one or more health conditions or limited their ability to work or perform daily activities. The findings highlight “the detrimental ripple effects of delaying or forgoing care on overall health, functioning, and well-being,” researchers write.

The survey, conducted among 4,007 U.S. adults aged 18-64 in September 2020, found that adults with one or more chronic conditions were more likely than adults without chronic conditions to have delayed or missed care (40.7% vs. 26.4%). Adults with a mental health condition were particularly likely to have delayed or gone without care, write Dulce Gonzalez, MPP, a research associate in the Health Policy Center at the Urban Institute, and colleagues.

Doctors are already seeing the consequences of the missed visits, says Jacqueline W. Fincher, MD, president of the American College of Physicians.

Two of her patients with chronic conditions missed appointments last year. By the time they resumed care in 2021, their previsit lab tests showed significant kidney deterioration.

“Lo and behold, their kidneys were in failure. … One was in the hospital for 3 days and the other one was in for 5 days,” said Dr. Fincher, who practices general internal medicine in Georgia.

Dr. Fincher’s office has been proactive about calling patients with chronic diseases who missed follow-up visits or laboratory testing or who may have run out of medication, she said.

In her experience, delays mainly have been because of patients postponing visits. “We have stayed open the whole time now,” Dr. Fincher said. Her office offers telemedicine visits and in-person visits with safety precautions.

Still, some patients have decided to postpone care during the pandemic instead of asking their primary care doctor what they should do.

“We do know that chronic problems left without appropriate follow-up can create worse problems for them in terms of stroke, heart attack, and end organ damage,” Dr. Fincher said.
 

Lost lives

Future studies may help researchers understand the effects of delayed and missed care during the pandemic, said Russell S. Phillips, MD, director of the Center for Primary Care at Harvard Medical School, Boston.

“Although it is still early, and more data on patient outcomes will need to be collected, I anticipate that the ... delays in diagnosis, in cancer screening, and in management of chronic illness will result in lost lives and will emphasize the important role that primary care plays in saving lives,” Dr. Phillips said.

During the first several months of the pandemic, there were fewer diagnoses of hypertension, diabetes, and depression, Dr. Phillips said.

“In addition, and most importantly, the mortality rate for non-COVID conditions increased, suggesting that patients were not seeking care for symptoms of stroke or heart attack, which can be fatal if untreated,” he said. “We have also seen substantial decreases in cancer screening tests such as colonoscopy, and modeling studies suggest this will cost more lives based on delayed diagnoses of cancer.”

Vaccinating patients against COVID-19 may help primary care practices and patients get back on track, Dr. Phillips suggested.

In the meantime, some patients remain reluctant to come in. “Volumes are still lower than prepandemic, so it is challenging to overcome what is likely to be pent-up demand,” he told this news organization in an email. “Additionally, the continued burden of evaluating, testing, and monitoring patients with COVID or COVID-like symptoms makes it difficult to focus on chronic illness.”
 

 

 

Care most often skipped

The Urban Institute survey asked respondents about delays in prescription drugs, general doctor and specialist visits, going to a hospital, preventive health screenings or medical tests, treatment or follow-up care, dental care, mental health care or counseling, treatment or counseling for alcohol or drug use, and other types of medical care.

Dental care was the most common type of care that adults delayed or did not receive because of the pandemic (25.3%), followed by general doctor or specialist visits (20.6%) and preventive health screenings or medical tests (15.5%).

Black adults were more likely than White or Hispanic/Latinx adults to have delayed or forgone care (39.7% vs. 34.3% and 35.5%), the researchers found. Compared with adults with higher incomes, adults with lower incomes were more likely to have missed multiple types of care (26.6% vs. 20.3%).

The report by the Urban Institute researchers was supported by the Robert Wood Johnson Foundation. Dr. Phillips is an adviser to two telemedicine companies, Bicycle Health and Grow Health. Dr. Fincher has disclosed no relevant financial disclosures.

Semaglutide for meaningful weight loss in obesity and diabetes?

Article Type
Changed

A 2.4-mg weekly injection of the glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide led to a clinically meaningful 5% loss in weight for roughly two-thirds of patients with both overweight/obesity and type 2 diabetes, researchers report.

These findings from the Semaglutide Treatment Effect in People With Obesity 2 (STEP 2) trial, one of four phase 3 trials of this drug, which is currently under regulatory review for weight loss, were published March 2 in The Lancet.

More than 1,000 patients (mean initial weight, 100 kg [220 pounds]) were randomly assigned to receive a lifestyle intervention plus a weekly injection of semaglutide 2.4 mg or semaglutide 1.0 mg or placebo. At 68 weeks, they had lost a mean of 9.6%, 7.0%, and 3.4%, respectively, of their starting weight.

In addition, 69% of patients who had received semaglutide 2.4 mg experienced a clinically meaningful 5% loss of weight, compared with 57% of patients who had received the lower dose and 29% of patients who had received placebo.

The higher dose of semaglutide was associated with a greater improvement in cardiometabolic risk factors. The safety profile was similar to that seen with other drugs in this class.
 

“By far the best results with any weight loss medicine in diabetes”

Importantly, “more than a quarter of participants lost over 15% of their body weight,” senior author Ildiko Lingvay, MD, stressed. This “is by far the best result we had with any weight loss medicine in patients with diabetes,” Dr. Lingvay, of the University of Texas, Dallas, said in a statement from the university.

“The drug works by suppressing appetite centers in the brain to reduce caloric intake,” she explained. “The medication continually tells the body that you just ate, you’re full.”

Similarly, lead author Melanie J. Davies, MD, said that the STEP 2 results “are exciting and represent a new era in weight management in people with type 2 diabetes.

“They mark a real paradigm shift in our ability to treat obesity,” with results closer to those achieved with bariatric surgery, Dr. Davies, of the University of Leicester, England, said in a statement from her institution.

“It is really encouraging,” she continued, “that along with the weight loss we saw real improvements in general health, with significant improvement in physical functioning scores, blood pressure, and blood glucose control.”

Dr. Lingvay noted that on average, patients in the four STEP clinical trials lost 10%-17% of their body weight, “which is a huge step forward compared with all other medications currently available to treat obesity.” She stressed that these results are comparable to the 20%-30% weight loss seen with bariatric surgery.
 

One of four trials under review

More than 90% of people with type 2 diabetes are overweight or have obesity, and more than 20% of people with obesity have diabetes, wrote Dr. Davies and colleagues.

Semaglutide (Ozempic), administered subcutaneously at a dose of 0.5 mg to 1 mg weekly, is approved by the Food and Drug Administration for the treatment of type 2 diabetes. Dosing studies indicated that it is associated with weight loss.

As previously reported, four trials of the use of semaglutide for weight loss (STEP 1, 2, 3, and 4) have been completed. The combined data were submitted to the FDA on Dec. 4, 2020 (a decision is expected within 6 months) and to the European Medicines Agency on Dec. 18, 2020.

The STEP 1 and STEP 3 trials of semaglutide 2.4 mg vs. placebo were recently published. The STEP 1 trial involved 1,961 adults with obesity or overweight; the STEP 3 trial, 611 adults with obesity or overweight. In each of the trials, some patients also underwent an intensive lifestyle intervention, and some did not. In both trials, patients with type 2 diabetes were excluded.

Topline results from STEP 2 were reported in June 2020.

STEP 2 involved 1,210 adults in 149 outpatient clinics in 12 countries in Europe, North America, South America, the Middle East, South Africa, and Asia. All participants had type 2 diabetes.

For all patients, the body mass index was ≥27 kg/m2, and the A1c concentration was 7%-10%. The mean BMI was 35.7 kg/m2, and the mean A1c was 8.1%.

The mean age of the patients was 55 years, and 51% were women; 62% were White, 26% were Asian, 13% were Hispanic, 8% were Black, and 4% were of other ethnicity.

Participants were managed with diet and exercise alone or underwent treatment with a stable dose of up to three oral glucose-lowering agents (metformin, sulfonylureas, SGLT2 inhibitors, or thiazolidinediones) for at least 90 days. They were then randomly assigned in 1:1:1 ratio to receive semaglutide 2.4 mg, semaglutide 1.0 mg, or placebo.

The starting dose of semaglutide was 0.25 mg/wk; the dose was escalated every 4 weeks to reach the target dose.

All patients received monthly counseling from a dietitian about calories (the goal was a 500-calorie/day deficit) and activity (the goal was 150 minutes of walking or stair climbing per week).

The mean A1c dropped by 1.6% and 1.5% in the semaglutide groups and by 0.4% in the placebo group.

Adverse events were more frequent among the patients who received semaglutide (88% and 82%) than in the placebo group (77%).

Gastrointestinal events that were mainly mild to moderate in severity were reported by 64% of patients in the 2.4-mg semaglutide group, 58% in the 1.0-mg semaglutide group, and 34% in the placebo group.

Semaglutide (Rybelsus) is approved in the United States as a once-daily oral agent for use in type 2 diabetes in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.

The study was supported by Novo Nordisk. The authors’ relevant financial relationships are listed in the original article.

A 2.4-mg weekly injection of the glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide led to a clinically meaningful 5% loss in weight for roughly two-thirds of patients with both overweight/obesity and type 2 diabetes, researchers report.

These findings from the Semaglutide Treatment Effect in People With Obesity 2 (STEP 2) trial, one of four phase 3 trials of this drug, which is currently under regulatory review for weight loss, were published March 2 in The Lancet.

More than 1,000 patients (mean initial weight, 100 kg [220 pounds]) were randomly assigned to receive a lifestyle intervention plus a weekly injection of semaglutide 2.4 mg or semaglutide 1.0 mg or placebo. At 68 weeks, they had lost a mean of 9.6%, 7.0%, and 3.4%, respectively, of their starting weight.

In addition, 69% of patients who had received semaglutide 2.4 mg experienced a clinically meaningful 5% loss of weight, compared with 57% of patients who had received the lower dose and 29% of patients who had received placebo.

The higher dose of semaglutide was associated with a greater improvement in cardiometabolic risk factors. The safety profile was similar to that seen with other drugs in this class.
 

“By far the best results with any weight loss medicine in diabetes”

Importantly, “more than a quarter of participants lost over 15% of their body weight,” senior author Ildiko Lingvay, MD, stressed. This “is by far the best result we had with any weight loss medicine in patients with diabetes,” Dr. Lingvay, of the University of Texas, Dallas, said in a statement from the university.

“The drug works by suppressing appetite centers in the brain to reduce caloric intake,” she explained. “The medication continually tells the body that you just ate, you’re full.”

Similarly, lead author Melanie J. Davies, MD, said that the STEP 2 results “are exciting and represent a new era in weight management in people with type 2 diabetes.

“They mark a real paradigm shift in our ability to treat obesity,” with results closer to those achieved with bariatric surgery, Dr. Davies, of the University of Leicester, England, said in a statement from her institution.

“It is really encouraging,” she continued, “that along with the weight loss we saw real improvements in general health, with significant improvement in physical functioning scores, blood pressure, and blood glucose control.”

Dr. Lingvay noted that on average, patients in the four STEP clinical trials lost 10%-17% of their body weight, “which is a huge step forward compared with all other medications currently available to treat obesity.” She stressed that these results are comparable to the 20%-30% weight loss seen with bariatric surgery.
 

One of four trials under review

More than 90% of people with type 2 diabetes are overweight or have obesity, and more than 20% of people with obesity have diabetes, wrote Dr. Davies and colleagues.

Semaglutide (Ozempic), administered subcutaneously at a dose of 0.5 mg to 1 mg weekly, is approved by the Food and Drug Administration for the treatment of type 2 diabetes. Dosing studies indicated that it is associated with weight loss.

As previously reported, four trials of the use of semaglutide for weight loss (STEP 1, 2, 3, and 4) have been completed. The combined data were submitted to the FDA on Dec. 4, 2020 (a decision is expected within 6 months) and to the European Medicines Agency on Dec. 18, 2020.

The STEP 1 and STEP 3 trials of semaglutide 2.4 mg vs. placebo were recently published. The STEP 1 trial involved 1,961 adults with obesity or overweight; the STEP 3 trial, 611 adults with obesity or overweight. In each of the trials, some patients also underwent an intensive lifestyle intervention, and some did not. In both trials, patients with type 2 diabetes were excluded.

Topline results from STEP 2 were reported in June 2020.
