Monoclonal antibody combo treatment reduces viral load in mild to moderate COVID-19

Thu, 08/26/2021 - 15:52

A combination treatment of neutralizing monoclonal antibodies bamlanivimab and etesevimab was associated with a statistically significant reduction in SARS-CoV-2 at day 11 compared with placebo among nonhospitalized patients who had mild to moderate COVID-19, new data indicate.

However, bamlanivimab alone in three different single-infusion doses showed no significant reduction in viral load, compared with placebo, according to the phase 2/3 study by Robert L. Gottlieb, MD, PhD, of the Baylor University Medical Center and the Baylor Scott & White Research Institute, both in Dallas, and colleagues.

Findings from the Blocking Viral Attachment and Cell Entry with SARS-CoV-2 Neutralizing Antibodies (BLAZE-1) study were published online Jan. 21 in JAMA. The results represent findings through Oct. 6, 2020.

BLAZE-1 was funded by Eli Lilly, which makes both of the antispike neutralizing antibodies. The trial was conducted at 49 U.S. centers and included 613 outpatients who tested positive for SARS-CoV-2 and had one or more mild to moderate symptoms.

Patients were randomized to one of five groups (four treatment groups and a placebo control), and researchers analyzed between-group differences.

All four treatment arms suggest a trend toward reduction in viral load, which was the primary endpoint of the trial, but only the combination showed a statistically significant reduction.

The average age of patients was 44.7 years, 54.6% were female, 42.5% were Hispanic, and 67.1% had at least one risk factor for severe COVID-19 (aged ≥55 years, body mass index of at least 30, or relevant comorbidity such as hypertension).

Among secondary outcomes, there were no consistent differences between the monotherapy groups or the combination group versus placebo for the other measures of viral load or clinical symptom scores.

The proportion of patients who had COVID-19–related hospitalizations or ED visits was 5.8% (nine events) for placebo; 1.0% (one event) for the 700-mg group; 1.9% (two events) for 2,800 mg; 2.0% (two events) for 7,000 mg; and 0.9% (one event) for combination treatment.

“Combining these two neutralizing monoclonal antibodies in clinical use may enhance viral load reduction and decrease treatment-emergent resistant variants,” the authors concluded.
 

Safety profile comparison

As for adverse events, immediate hypersensitivity reactions were reported in nine patients (six bamlanivimab, two combination treatment, and one placebo). No deaths occurred during the study.

Serious adverse events unrelated to SARS-CoV-2 infection or considered related to the study drug occurred in 0% (0/309) of patients in the bamlanivimab monotherapy groups; in 0.9% (1/112) of patients in the combination group; and in 0.6% (1/156) of patients in the placebo group.

The serious adverse event in the combination group was a urinary tract infection deemed unrelated to the study drug, the authors wrote.

The two most frequently reported side effects were nausea (3.0% for the 700-mg group; 3.7% for the 2,800-mg group; 5.0% for the 7,000-mg group; 3.6% for the combination group; and 3.8% for the placebo group) and diarrhea (1.0%, 1.9%, 5.9%, 0.9%, and 4.5%, respectively).

The authors included in the study’s limitations that the primary endpoint at day 11 may have been too late to best detect treatment effects.

“All patients, including those who received placebo, demonstrated substantial viral reduction by day 11,” they noted. “An earlier time point like day 3 or day 7 could possibly have been more appropriate to measure viral load.”

Currently, only remdesivir has been approved by the Food and Drug Administration for treating COVID-19, but convalescent plasma and neutralizing monoclonal antibodies have been granted emergency-use authorization.

In an accompanying editor’s note, Preeti N. Malani, MD, with the division of infectious diseases at the University of Michigan, Ann Arbor, and associate editor of JAMA, and Robert M. Golub, MD, deputy editor of JAMA, pointed out that these results differ from an earlier interim analysis of BLAZE-1 data.

previous publication by Peter Chen, MD, with the department of medicine at Cedars Sinai Medical Center, Los Angeles, compared the three monotherapy groups (no combination group) with placebo, and in that study the 2,800-mg dose of bamlanivimab versus placebo achieved statistical significance for reduction in viral load from baseline at day 11, whereas the other two doses did not.

The editors explain that, in the study by Dr. Chen, “Follow-up for the placebo group was incomplete at the time of the database lock on Sept. 5, 2020. In the final analysis reported in the current article, the database was locked on Oct. 6, 2020, and the longer follow-up for the placebo group, which is now complete, resulted in changes in the primary outcome among that group.”

They concluded: “The comparison of the monotherapy groups against the final results for the placebo group led to changes in the effect sizes,” and the statistical significance of the 2,800-mg group was erased.

The editors pointed out that monoclonal antibodies are likely to benefit certain patients but definitive answers regarding which patients will benefit and under what circumstances will likely take more time than clinicians have to make decisions on treatment.

Meanwhile, as this news organization reported, the United States has spent $375 million on bamlanivimab and $450 million on Regeneron’s monoclonal antibody cocktail of casirivimab plus imdevimab, with the promise to spend billions more.

However, 80% of the 660,000 doses delivered by the two companies are still sitting on shelves, federal officials said in a press briefing last week, because of doubts about efficacy, lack of resources for infusion centers, and questions on reimbursement.

“While the world waits for widespread administration of effective vaccines and additional data on treatments, local efforts should work to improve testing access and turnaround time and reduce logistical barriers to ensure that monoclonal therapies can be provided to patients who are most likely to benefit,” Dr. Malani and Dr. Golub wrote.

This trial was sponsored and funded by Eli Lilly. Dr. Gottlieb disclosed personal fees and nonfinancial support (medication for another trial) from Gilead Sciences and serving on an advisory board for Sentinel. Several coauthors have financial ties to Eli Lilly. Dr. Malani reported serving on the National Institute of Allergy and Infectious Diseases COVID-19 Preventive Monoclonal Antibody data and safety monitoring board but was not compensated. Dr. Golub disclosed no relevant financial relationships.

ACEIs, ARBs safe to continue in COVID-19: Trial published

Article Type
Changed
Thu, 08/26/2021 - 15:52

The BRACE-CORONA trial, the first randomized trial to address the question of whether patients with COVID-19 should continue to take ACE inhibitors (ACEIs) or angiotensin-receptor blockers (ARBs) – has now been published.

The study, which was conducted in patients hospitalized with COVID-19 who were taking ACEIs or ARBs before hospitalization, showed no significant difference in the mean number of days alive and out of the hospital for those assigned to discontinue versus those assigned to continue these medications.

There were, however, hints that continuing to take ACEIs or ARBs may be beneficial for patients with more severe COVID-19.

The study was first presented at last year’s European Society of Cardiology Congress and was reported by this news organization at that time. The study was published online in JAMA on Jan. 19, 2021.

“These findings do not support routinely discontinuing ACEIs or ARBs among patients hospitalized with mild to moderate COVID-19 if there is an indication for treatment,” the authors concluded.

Led by Renato D. Lopes, MD, Duke Clinical Research Institute, Durham, N.C., the researchers explained that there has been conflicting speculation about the effect of renin-angiotensin-aldosterone system (RAAS) inhibitors on the course of COVID-19.

On the one hand, observations from animal models suggest that ACEIs and ARBs up-regulate the expression of ACE2, a receptor involved in SARS-CoV-2 infection of host target cells. This led to suggestions that these medications may enhance viral binding and cell entry. Conversely, RAAS inhibitors could benefit patients with COVID-19 through effects on angiotensin II expression and subsequent increases in angiotensin 1-7 and 1-9, which have vasodilatory and anti-inflammatory effects that might attenuate lung injury.

The BRACE-CORONA trial included 659 patients hospitalized in Brazil with mild to moderate COVID-19 who were taking ACEIs or ARBs prior to hospitalization. The median age of the patients was 55 years. Of these patients, 57.1% were considered to have mild cases at hospital admission, and 42.9% were considered to have moderate cases.

Results showed no significant difference in the number of days alive and out of the hospital for patients in the discontinuation group (mean, 21.9 days) in comparison with patients in the continuation group (mean, 22.9 days). The mean ratio was 0.95 (95% confidence interval, 0.90-1.01).

There also was no statistically significant difference in deaths (2.7% of the discontinuation group vs. 2.8% for the continuation group); cardiovascular death (0.6% vs. 0.3%), or COVID-19 progression (38.3% vs. 32.3%).

The most common adverse events were respiratory failure requiring invasive mechanical ventilation (9.6% in the discontinuation group vs. 7.7% in the continuation group), shock requiring vasopressors (8.4% vs. 7.1%), acute MI (7.5% vs. 4.6%), new or worsening heart failure (4.2% vs. 4.9%), and acute kidney failure requiring hemodialysis (3.3% vs. 2.8%).

The authors note that hypertension is an important comorbidity in patients with COVID-19. Recent data suggest that immune dysfunction may contribute to poor outcomes among patients who have COVID-19 and hypertension.

It has been shown that, when use of long-term medications is discontinued during hospitalization, the use of those medications is often not resumed, owing to clinical inertia. Long-term outcomes worsen as a result, the authors reported. In the current study, all patients had hypertension, and more than 50% were obese; both of these comorbidities increase the risk for poor outcomes with COVID-19.

The investigators pointed out that a sensitivity analysis in which site was regarded as a random effect showed a statistically significant finding in favor of the group that continued ACEIs or ARBs. This finding was similar to that of the on-treatment analysis. There were also statistically significant interactions between treatment effect and some subgroups, such as patients with lower oxygen saturation and greater disease severity at hospital admission. For these patients, continuing ACEIs or ARBs may be beneficial.

“The primary analyses with the null results but wide 95% confidence intervals suggest that the study might have been underpowered to detect a statistically significant benefit of continuing ACEIs or ARBs,” they said.

Dr. Lopes has received grant support from Bristol-Myers Squibb, GlaxoSmithKline, Medtronic, Pfizer, and Sanofi and consulting fees from Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Daiichi Sankyo, GlaxoSmithKline, Medtronic, Merck, Pfizer, Portola, and Sanofi.

On the one hand, observations from animal models suggest that ACEIs and ARBs up-regulate the expression of ACE2, a receptor involved in SARS-CoV-2 infection of host target cells. This led to suggestions that these medications may enhance viral binding and cell entry. Conversely, RAAS inhibitors could benefit patients with COVID-19 through effects on angiotensin II expression and subsequent increases in angiotensin 1-7 and 1-9, which have vasodilatory and anti-inflammatory effects that might attenuate lung injury.

The BRACE-CORONA trial included 659 patients hospitalized in Brazil with mild to moderate COVID-19 who were taking ACEIs or ARBs prior to hospitalization. The median age of the patients was 55 years. Of these patients, 57.1% were considered to have mild cases at hospital admission, and 42.9% were considered to have moderate cases.

Results showed no significant difference in the number of days alive and out of the hospital for patients in the discontinuation group (mean, 21.9 days) in comparison with patients in the continuation group (mean, 22.9 days). The mean ratio was 0.95 (95% confidence interval, 0.90-1.01).

There also was no statistically significant difference in deaths (2.7% of the discontinuation group vs. 2.8% for the continuation group); cardiovascular death (0.6% vs. 0.3%), or COVID-19 progression (38.3% vs. 32.3%).

The most common adverse events were respiratory failure requiring invasive mechanical ventilation (9.6% in the discontinuation group vs. 7.7% in the continuation group), shock requiring vasopressors (8.4% vs. 7.1%), acute MI (7.5% vs. 4.6%), new or worsening heart failure (4.2% vs. 4.9%), and acute kidney failure requiring hemodialysis (3.3% vs. 2.8%).

The authors note that hypertension is an important comorbidity in patients with COVID-19. Recent data suggest that immune dysfunction may contribute to poor outcomes among patients who have COVID-19 and hypertension.

It has been shown that, when use of long-term medications is discontinued during hospitalization, the use of those medications is often not resumed, owing to clinical inertia. Long-term outcomes worsen as a result, the authors reported. In the current study, all patients had hypertension, and more than 50% were obese; both of these comorbidities increase the risk for poor outcomes with COVID-19.

The investigators pointed out that a sensitivity analysis in which site was regarded as a random effect showed a statistically significant finding in favor of the group that continued ACEIs or ARBs. This finding was similar to that of the on-treatment analysis. There were also statistically significant interactions between treatment effect and some subgroups, such as patients with lower oxygen saturation and greater disease severity at hospital admission. For these patients, continuing ACEIs or ARBs may be beneficial.

“The primary analyses with the null results but wide 95% confidence intervals suggest that the study might have been underpowered to detect a statistically significant benefit of continuing ACEIs or ARBs,” they said.

President Joe Biden signed 10 new executive orders on his second day in office that are designed to help roll out his broader plan to fight COVID-19.

“For the past year, we couldn’t rely on the federal government to act with the urgency and focus and coordination we needed, and we have seen the tragic cost of that failure,” Mr. Biden said in remarks from the White House, unveiling his 198-page National Strategy for the COVID-19 Response and Pandemic Preparedness.

He said as many as 500,000 Americans will have died by February. “It’s going to take months for us to turn things around,” he said.

“Our national strategy is comprehensive – it’s based on science, not politics; it’s based on truth, not denial,” Mr. Biden said. He also promised to restore public trust, in part by having scientists and public health experts speak to the public. “That’s why you’ll be hearing a lot more from Dr. Fauci again, not from the president,” he said, adding that the experts will be “free from political interference.”

While the president’s executive orders can help accomplish some of the plan’s proposals, the majority will require new funding from Congress and will be included in the $1.9 trillion American Rescue package that Mr. Biden hopes legislators will approve.
 

Ten new orders

The 10 new pandemic-related orders Biden signed on Jan. 21 follow two he signed on his first day in office.

One establishes a COVID-19 Response Office responsible for coordinating the pandemic response across all federal departments and agencies and also reestablishes the White House Directorate on Global Health Security and Biodefense, which was disabled by the Trump administration.

The other order requires masks and physical distancing in all federal buildings, on all federal lands, and by federal employees and contractors.

Among the new orders will be directives that:

  • Require individuals to also wear masks in airports and planes, and when using other modes of public transportation including trains, boats, and intercity buses, and also require international travelers to produce proof of a recent negative COVID-19 test prior to entry and to quarantine after entry.
  • Federal agencies use all powers, including the Defense Production Act, to accelerate manufacturing and delivery of supplies such as N95 masks, gowns, gloves, swabs, reagents, pipette tips, rapid test kits, and nitrocellulose material for rapid antigen tests, and all equipment and material needed to accelerate manufacture, delivery, and administration of COVID-19 vaccine.
  • Create a Pandemic Testing Board to expand supply and access, to promote more surge capacity, and to ensure equitable access to tests.
  • Facilitate discovery, development, and trials of potential COVID-19 treatments, as well as expand access to programs that can meet the long-term health needs of those recovering from the disease.
  • Facilitate more and better data sharing that will allow businesses, schools, hospitals, and individuals to make real-time decisions based on spread in their community.
  • Direct the Education and Health & Human Services departments to provide schools and child-care operations guidance on how to reopen and operate safely.
  • Direct the Occupational Safety and Health Administration (OSHA) to immediately release clear guidance for employers to help keep workers safe and to enforce health and safety requirements.
 

 

The plan also sets goals for vaccination – including 100 million shots in the administration’s first 100 days. President Biden had already previewed his goals for vaccination, including setting up mass vaccination sites and mobile vaccination sites. During his remarks, Mr. Biden said that he had already directed the Federal Emergency Management Agency (FEMA) to begin setting up the vaccination centers.

The administration is also going to look into improving reimbursement for giving vaccines. As a start, the HHS will ask the Centers for Medicare & Medicaid Services to consider if a higher rate “may more accurately compensate providers,” according to the Biden plan.

“But the brutal truth is it will take months before we can get the majority of Americans vaccinated,” said Mr. Biden.

As part of the goal of ensuring an equitable pandemic response, the president will sign an order that establishes a COVID-19 Health Equity Task Force. The task force is charged with providing recommendations for allocating resources and funding in communities with inequities in COVID-19 outcomes by race, ethnicity, geography, disability, and other considerations.

Finally, the administration has committed to being more transparent and sharing more information. The national plan calls for the federal government to conduct regular, expert-led, science-based public briefings and to release regular reports on the pandemic. The administration said it will launch massive science-based public information campaigns – in multiple languages – to educate Americans on masks, testing, and vaccines, and also work to counter misinformation and disinformation.

The American Academy of Family Physicians (AAFP) applauded Mr. Biden’s initiative. “If enacted, this bold legislative agenda will provide much-needed support to American families struggling during the pandemic – especially communities of color and those hardest hit by the virus,” Ada D. Stewart, MD, AAFP president, said in a statement.

Dr. Stewart also noted that family physicians “are uniquely positioned in their communities to educate patients, prioritize access, and coordinate administration of the COVID-19 vaccines,” and urged the administration to ensure that family physicians and staff be vaccinated as soon as possible, to help them “more safely provide care to their communities.”

Metformin treatment again linked to fewer deaths from COVID-19

Article Type
Changed
Thu, 08/26/2021 - 15:52

People with type 2 diabetes who develop COVID-19 show a substantially reduced risk of dying if they are taking metformin, shows a study that adds to prior research indicating the drug might somehow play a role in reducing the severity of infection.

“Unlike several previous analyses, this was a study in a racially diverse population with a high proportion of Blacks/African Americans and [it] revealed that metformin treatment of diabetes prior to diagnosis with COVID-19 was associated with a dramatic threefold reduced mortality in subjects with type 2 diabetes, even after correcting for multiple covariates,” first author Anath Shalev, MD, of the Comprehensive Diabetes Center at the University of Alabama at Birmingham, said in an interview.

But Anne Peters, MD, a professor of clinical medicine at the University of Southern California, Los Angeles, said caution is needed when interpreting these findings.

“It’s hard to tease out the true effects because, for instance, those treated with insulin may be a sicker subset of patients with diabetes than those on metformin, or those with comorbidities such as renal insufficiency may not be treated with metformin” she said in an interview.

“In general, though, treatment obviously matters and people who are better treated tend to do better, so while I think this study raises the question of what role metformin plays in the risk of mortality and COVID-19, I don’t think it necessarily proves the association,” Dr. Peters asserted.
 

Diverse population

The new study, published this month in Frontiers of Endocrinology, included 25,326 individuals who were tested for COVID-19 at the University of Alabama at Birmingham Hospital between February and June 2020.

Overall, 2.4% tested positive for COVID-19 (n = 604), which the authors note is likely a low figure because screening included asymptomatic hospital staff and patients having elective procedures.

Black/African American patients had a significantly higher risk of COVID-19 positivity, compared with White patients (odds ratio, 2.6; P < .0001). Rates were also higher among those with hypertension (OR, 2.46), diabetes (OR, 2.11), and obesity (OR, 1.93), compared with those without each condition (all P < .0001).

The overall mortality rate in COVID-19-positive patients was 11%. Diabetes was associated with a dramatically increased risk of death (OR, 3.62; P < .0001), and remained an independent risk factor even after adjusting for age, race, sex, obesity, and hypertension.

Notably, the reduction in mortality among those with diabetes taking metformin prior to COVID-19 diagnosis was significant: 11% of those patients died, compared with 23% of those with diabetes not taking metformin (OR, 0.33; P = .021).
 

Similar findings reported across varied populations

The study adds to mounting research suggesting metformin could have a protective effect on COVID-19 mortality, including an early report from Wuhan, China, findings from the French CORONADO study, and a U.S. study linking treatment with decreased mortality among women with COVID-19.

Of note, the effects of metformin on mortality in the current study were observed in men and women alike, as well as in high-risk subgroups including African Americans.

“The fact that such similar results were obtained in different populations from around the world suggests that the observed reduction in mortality risk, associated with metformin use in subjects with type 2 diabetes and COVID-19, might be generalizable,” the authors wrote.

“Furthermore, these findings underline the importance of following general diabetes treatment and prevention guidelines and not delaying or discontinuing any metformin treatment,” they add.
 

 

 

Speculation of mechanisms includes anti-inflammatory effects

While the mechanisms behind metformin’s potential role in reducing mortality risk in COVID-19 are unknown, the authors note that the most obvious assumption – that improved glycemic control may be a key factor – is disputed by the study’s finding that blood glucose levels and hemoglobin A1c were not significantly different among COVID-19 survivors taking versus not taking metformin.

They point instead to metformin’s known anti-inflammatory and antithrombotic properties.

“We therefore hypothesize that, by exerting some of these effects, metformin might improve outcomes and we are now in the process of investigating this possibility further,” Dr. Shalev said.

Dr. Peters noted that anti-inflammatory properties, themselves, are not necessarily unique to metformin in the treatment of diabetes.

“Many other agents, such as sodium-glucose cotransporter 2 (SGLT2) inhibitors can reduce inflammation, so I don’t know if that would explain it, but it certainly could help,” she said. “[Reducing inflammation] is a hypothesis you see commonly with diabetes drugs, but I think there are also a lot of metabolic benefits from metformin.”

“It was fascinating that they had the A1c data and that survival with metformin didn’t appear to be as related to A1c levels as one might think,” she added.

Notably, a key advantage, should the effects and mechanisms be validated, is metformin’s high accessibility, Dr. Peters added.

“This doesn’t necessarily tell us what we can do to reduce the health care disparities surrounding COVID-19, but the fact that metformin is low cost and easily available is very important, so maybe it will help as we try to grapple with other risk factors.”

The authors have reported no relevant financial relationships.

Of note, the effects of metformin on mortality in the current study were observed in men and women alike, as well as in high-risk subgroups including African Americans.

“The fact that such similar results were obtained in different populations from around the world suggests that the observed reduction in mortality risk, associated with metformin use in subjects with type 2 diabetes and COVID-19, might be generalizable,” the authors wrote.

“Furthermore, these findings underline the importance of following general diabetes treatment and prevention guidelines and not delaying or discontinuing any metformin treatment,” they add.
 

 

 

Speculation of mechanisms includes anti-inflammatory effects

While the mechanisms behind metformin’s potential role in reducing mortality risk in COVID-19 are unknown, the authors note that the most obvious assumption – that improved glycemic control may be a key factor – is disputed by the study’s finding that blood glucose levels and hemoglobin A1c were not significantly different among COVID-19 survivors taking versus not taking metformin.

They point instead to metformin’s known anti-inflammatory and antithrombotic properties.

“We therefore hypothesize that, by exerting some of these effects, metformin might improve outcomes and we are now in the process of investigating this possibility further,” Dr. Shalev said.

Dr. Peters noted that anti-inflammatory properties, themselves, are not necessarily unique to metformin in the treatment of diabetes.

“Many other agents, such as sodium-glucose cotransporter 2 (SGLT2) inhibitors can reduce inflammation, so I don’t know if that would explain it, but it certainly could help,” she said. “[Reducing inflammation] is a hypothesis you see commonly with diabetes drugs, but I think there are also a lot of metabolic benefits from metformin.”

“It was fascinating that they had the A1c data and that survival with metformin didn’t appear to be as related to A1c levels as one might think,” she added.

Notably, a key advantage, should the effects and mechanisms be validated, is metformin’s high accessibility, Dr. Peters added.

“This doesn’t necessarily tell us what we can do to reduce the health care disparities surrounding COVID-19, but the fact that metformin is low cost and easily available is very important, so maybe it will help as we try to grapple with other risk factors.”

Seven ways President Biden could now change health care

Article Type

Thu, 08/26/2021 - 15:52

President Joe Biden has come into office after an unexpected shift in Congress. On Jan. 5, Democrats scored an upset by winning two U.S. Senate seats in runoff elections in Georgia, giving them control of the Senate.

Now the Democrats have control of all three levers of power – the Senate, the House, and the presidency – for the first time since the early years of the Obama administration.

How will President Biden use this new concentration of power to shape health care policy?

Democrats’ small majorities in both houses of Congress suggest that moderation and bipartisanship will be necessary to get things done. Moreover, Mr. Biden himself is calling for bipartisanship. “On this January day,” he said in his inauguration speech, “my whole soul is in this: Bringing America together, uniting our people, uniting our nation.”

Key health care actions that Mr. Biden could pursue include the following.
 

1. Passing a new COVID-19 relief bill

Above all, Mr. Biden is focused on overcoming the COVID-19 pandemic, which has been registering record deaths recently, and getting newly released vaccines to Americans.

“Dealing with the coronavirus pandemic is one of the most important battles our administration will face, and I will be informed by science and by experts,” the president said.

“There is no question that the pandemic is the highest priority for the Biden administration,” said Larry Levitt, executive vice president for health policy at the Henry J. Kaiser Family Foundation. “COVID will dominate the early weeks and months of this administration. His success rests, in particular, on improving the rollout of vaccines.”

Five days before his inauguration, the president-elect unveiled the American Rescue Plan, a massive, $1.9 trillion legislative package intended to hasten rollout of COVID-19 vaccines, improve COVID-19 testing, and provide financial help to businesses and individuals, among many other things.

The bill would add $1,400 to the recently passed $600 government relief payments for each American, amounting to a $2,000 check. It would also enact many non-COVID-19 measures, such as a $15-an-hour minimum wage and measures to bolster the Affordable Care Act (ACA).

If Democrats cannot reach a deal with the Republicans, they might turn the proposal into a reconciliation bill, which could then be passed with a simple majority. However, drafting a reconciliation bill is a long, complicated process that would require removing provisions that don’t meet the requirements of reconciliation, said Hazen Marshall, a Washington lobbyist and former staffer for Sen. Mitch McConnell.

Most importantly, Mr. Marshall said, reconciliation bills bring out diehard partisanship. “They involve a sledgehammer mentality,” he says. “You’re telling the other side that their views aren’t going to matter.” The final version of the ACA, for example, was passed as a reconciliation bill, with not one Republican vote.

In the Trump years, “the last four reconciliation bills did not get any votes from the minority,” added Rodney Whitlock, PhD, a political consultant at McDermott+Consulting, who worked 21 years for Republicans in the House. “When the majority chooses to use reconciliation, it is an admission that it has no interest in working with the minority.”

Hammering out a compromise will be tough, but Robert Pearl MD, former CEO of the Permanente Medical Group and a professor at Stanford (Calif.) University, said that if anyone can do it, it would be President Biden. Having served in the Senate for 36 years, “Biden knows Congress better than any president since Lyndon Johnson,” he said. “He can reach across the aisle and get legislation passed as much as anyone could these days.”
 

 

 

2. Restoring Obamacare

Mr. Biden has vowed to undo a gradual dismantling of the ACA that went on during the Trump administration through executive orders, rule-making, and new laws. “Reinvigorating the ACA was a central part of Biden’s platform as a candidate,” Mr. Levitt said.

Each Trump action against the ACA must be undone in the same way. Presidential orders must be met with presidential orders, regulations with regulations, and legislation with legislation.

The ACA is also being challenged in the Supreme Court. Republicans under Trump passed a law that reduced the penalty for not buying health insurance under the ACA to zero. Then a group of 20 states, led by Texas, filed a lawsuit asserting that this change makes the ACA unconstitutional.

The lawsuit was heard by the Supreme Court in November. From remarks made by the justices then, it appears that the court might well uphold the law when a verdict comes down in June.

But just in case, Mr. Biden wants Congress to enact a small penalty for not buying health insurance, which would remove the basis of the lawsuit.

Mr. Biden’s choice for secretary of Health and Human Services shows his level of commitment to protecting the ACA. His HHS nominee is California Attorney General Xavier Becerra, who led a group of 17 states defending the ACA in the current lawsuit.

In addition to undoing Trump’s changes, Mr. Biden plans to expand the ACA beyond the original legislation. The new COVID-19 bill contains provisions that would expand subsidies to buy insurance on the exchanges and would lower the maximum percentage of income that anyone has to pay for health insurance to 8.5%.

Dealing with Medicaid is also related to the ACA. In 2012, the Supreme Court struck down a mandate that states expand their Medicaid programs, with substantial funding from the federal government.

To date, 12 states still do not participate in the Medicaid expansion. To lure them into the expansion, the Democrat-controlled House last session passed a bill that would offer to pay the entire bill for the first 3 years of Medicaid expansion if they chose to enact an expansion.
 

3. Undoing other Trump actions in health care

In addition to changes in the ACA, Trump also enacted a number of other changes in health care that President Biden could undo. For example, Mr. Biden says he will reenter the World Health Organization (WHO) so that the United States could better coordinate a COVID-19 response with other nations. Trump exited the WHO with the stroke of a pen, and Mr. Biden can do the same in reverse.

Under Trump, the Centers for Medicare & Medicaid Services used waivers to weaken the ACA and allow states to alter their Medicaid programs. One waiver allows Georgia to leave the ACA exchanges and put brokers in charge of buying coverage. Other waivers allow states to transform federal Medicaid payments into block grants, which several states are planning to do.

The Trump CMS has allowed several states to use Medicaid waivers to add work requirements for Medicaid recipients. The courts have blocked the work rules so far, and the Biden CMS may decide to reverse these waivers or modify them.

“Undoing waivers is normally a fairly simple thing,” Mr. Levitt said. In January, however, the Trump CMS asked some waiver states to sign new contracts in which the CMS pledges not to end a waiver without 9 months’ notice. It’s unclear how many states signed such contracts and what obligation the Biden CMS has to enforce them.

The Trump CMS also stopped reimbursing insurers for waiving deductibles and copayments for low-income customers, as directed by the ACA. Without federal reimbursement, some insurers raised premiums by as much as 20% to cover the costs. It is unclear how the Biden CMS would tackle this change.
 

 

 

4. Negotiating lower drug prices

Allowing Medicare to negotiate drug prices, a major plank in Mr. Biden’s campaign, would seem like a slam dunk for the Democrats. This approach is backed by 89% of Americans, including 84% of Republicans, according to a Kaiser Family Foundation survey in December.

“With that level of support, it’s hard to go wrong politically on this issue,” Mr. Levitt said.

Many Republicans, however, do not favor negotiating drug prices, and the two parties continue to be far apart on how to control drug prices. Trump signed an action that allows Americans to buy cheaper drugs abroad, an approach that Mr. Biden also supports, but it is now tied up in the courts.

“A drug pricing bill has always been difficult to pass,” Dr. Whitlock said. “The issue is popular with the public, but change does not come easily. The drug lobby is one the strongest in Washington, and now it may be even stronger, since it was the drug companies that gave us the COVID vaccines.”

Dr. Whitlock said Republicans will want Democrats to compromise on drug pricing, but he doubts they will do so. The House passed a bill to negotiate drug prices last year, which never was voted on in the Senate. “It is difficult to imagine that the Democrats will be able to move rightward from that House bill,” Dr. Whitlock said. “Democrats are likely to stand pat on drug pricing.”
 

5. Introducing a public option

President Biden’s campaign proposal for a public option – health insurance offered by the federal government – and to lower the age for Medicare eligibility from 65 years to 60 years, resulted from a compromise between two factions of the Democratic party on how to expand coverage.

Although Mr. Biden and other moderates wanted to focus on fixing the ACA, Democrats led by Sen. Bernie Sanders of Vermont called for a single-payer system, dubbed “Medicare for all.” A public option was seen as the middle ground between the two camps.

“A public option would be a very controversial,” Dr. Whitlock said. Critics say it would pay at Medicare rates, which would reduce doctors’ reimbursements, and save very little money compared with a single-payer system.

Dr. Pearl sees similar problems with lowering the Medicare age. “This would be an expensive change that the federal government could not afford, particularly with all the spending on the pandemic,” he said. “And it would be tough on doctors and hospitals, because Medicare pays less than the private insurance payment they are now getting.”

“The public option is likely to get serious discussion within the Democratic caucus and get onto the Senate floor,” Mr. Levitt said. “The party won’t ignore it.” He notes that in the new Senate, Sen. Sanders chairs the budget committee, and from that position he is likely to push for expanding access to care.

Mr. Levitt says the Biden CMS might allow states to experiment with a statewide public option or even a single-payer model, but he concedes that states, with their budgets ravaged by COVID-19, do not currently have the money to launch such programs.
 

 

 

6. Reviving the CMS

Under President Obama, the CMS was the engine that implemented the ACA and shepherded wider use of value-based reimbursements, which reward providers for quality and outcomes rather than volume.

Under the Trump administration, CMS leadership continued to uphold value-based reimbursement, Dr. Pearl observed. “CMS leadership championed value-based payments, but they encountered a lot of pushback from doctors and hospitals and had to scale back their goals,” he said.

On the other hand, the Trump CMS took a 180-degree turn on the ACA and worked to take it apart. This took a toll on staff morale, according to Donald M. Berwick, MD, who ran the CMS under President Obama. “Many people in CMS did not feel supported during the Trump administration, and some of them left,” Dr. Berwick said.

The CMS needs experienced staff on board to write comprehensible rules and regulations that can overcome court challenges.

Having a fully functioning CMS also requires consistent leadership, which was a problem for Obama. When Mr. Obama nominated Dr. Berwick, 60 Senate votes were needed to confirm him, and Republicans would not vote for him. Mr. Obama eventually brought Dr. Berwick in as a recess appointment, but it meant he could serve for only 17 months.

Since then, Senate confirmation rules have changed so that only a simple majority is needed to confirm appointments. This is important for Biden’s nominees, Dr. Berwick said. “For a president, having your team in place means you are able to execute the policies you want,” he said. “You need to have consistent leadership.”
 

7. Potentially changing health care without Congress

Even with their newly won control of the Senate, the Democrats’ thin majorities in both houses of Congress may not be enough to pass much legislation if Republicans are solidly opposed.

Democrats in the House also have a narrow path this session in which to pass legislation. The Democratic leadership has an 11-vote majority, but it must contend with 15 moderate representatives in purple districts (where Democrats and Republicans have about equal support).

A bigger problem looms before the Democrats. In 2022, the party may well lose its majorities in both houses. Mr. Whitlock notes that the party of an incoming president normally loses seats in the first midterm election. “The last incoming president to keep both houses of Congress in his first midterm was Jimmy Carter,” he said.

If this happens, President Biden would have to govern without the support of Congress, which is what Barack Obama had to do through most of his presidency. As Mr. Obama’s vice president, Mr. Biden is well aware how that goes. Governing without Congress means relying on presidential orders and decrees.

In health care, Mr. Biden has a powerful policy-making tool, the Center for Medicare & Medicaid Innovation (CMMI). The CMMI was empowered by the ACA to initiate pilot programs for new payment models.

So far, the CMMI’s work has been mainly limited to accountable care organizations, bundled payments, and patient-centered medical homes, but it could also be used to enact new federal policies that would normally require Congressional action, Mr. Levitt said.
 

Conclusion

Expectations have been very high for what President Joe Biden can do in health care. He needs to unite a very divided political system to defeat a deadly pandemic, restore Obamacare, and sign landmark legislation, such as a drug-pricing bill.

But shepherding bills through Congress will be a challenge. “You need to have accountability, unity, and civility, which is a Herculean task,” Mr. Whitlock said. “You have to keep policies off the table that could blow up the bipartisanship.”

The new COVID-19 bill contains provisions that would expand subsidies to buy insurance on the exchanges and would lower the maximum percentage of income that anyone has to pay for health insurance to 8.5%.

Dealing with Medicaid is also related to the ACA. In 2012, the Supreme Court struck down a mandate that states expand their Medicaid programs, with substantial funding from the federal government.

To date, 12 states still do not participate in the Medicaid expansion. To lure them into the expansion, the Democrat-controlled House last session passed a bill that would offer to pay the entire bill for the first 3 years of Medicaid expansion if they chose to enact an expansion.
 

3. Undoing other Trump actions in health care

In addition to changes in the ACA, Trump also enacted a number of other changes in health care that President Biden could undo. For example, Mr. Biden says he will reenter the World Health Organization (WHO) so that the United States could better coordinate a COVID-19 response with other nations. Trump exited the WHO with the stroke of a pen, and Mr. Biden can do the same in reverse.

Under Trump, the Centers for Medicare & Medicaid Services used waivers to weaken the ACA and allow states to alter their Medicaid programs. One waiver allows Georgia to leave the ACA exchanges and put brokers in charge of buying coverage. Other waivers allow states to transform federal Medicaid payments into block grants, which several states are planning to do.

The Trump CMS has allowed several states to use Medicaid waivers to add work requirements for Medicaid recipients. The courts have blocked the work rules so far, and the Biden CMS may decide to reverse these waivers or modify them.

“Undoing waivers is normally a fairly simple thing,” Mr. Levitt said. In January, however, the Trump CMS asked some waiver states to sign new contracts in which the CMS pledges not to end a waiver without 9 months’ notice. It’s unclear how many states signed such contracts and what obligation the Biden CMS has to enforce them.

The Trump CMS also stopped reimbursing insurers for waiving deductibles and copayments for low-income customers, as directed by the ACA. Without federal reimbursement, some insurers raised premiums by as much as 20% to cover the costs. It is unclear how the Biden CMS would tackle this change.
 

 

 

4. Negotiating lower drug prices

Allowing Medicare to negotiate drug prices, a major plank in Mr. Biden’s campaign, would seem like a slam dunk for the Democrats. This approach is backed by 89% of Americans, including 84% of Republicans, according to a Kaiser Family Foundation survey in December.

“With that level of support, it’s hard to go wrong politically on this issue,” Mr. Levitt said.

Many Republicans, however, do not favor negotiating drug prices, and the two parties continue to be far apart on how to control drug prices. Trump signed an action that allows Americans to buy cheaper drugs abroad, an approach that Mr. Biden also supports, but it is now tied up in the courts.

“A drug pricing bill has always been difficult to pass,” Dr. Whitlock said. “The issue is popular with the public, but change does not come easily. The drug lobby is one the strongest in Washington, and now it may be even stronger, since it was the drug companies that gave us the COVID vaccines.”

Dr. Whitlock said Republicans will want Democrats to compromise on drug pricing, but he doubts they will do so. The House passed a bill to negotiate drug prices last year, which never was voted on in the Senate. “It is difficult to imagine that the Democrats will be able to move rightward from that House bill,” Dr. Whitlock said. “Democrats are likely to stand pat on drug pricing.”
 

5. Introducing a public option

President Biden’s campaign proposal for a public option – health insurance offered by the federal government – and to lower the age for Medicare eligibility from 65 years to 60 years, resulted from a compromise between two factions of the Democratic party on how to expand coverage.

Although Mr. Biden and other moderates wanted to focus on fixing the ACA, Democrats led by Sen. Bernie Sanders of Vermont called for a single-payer system, dubbed “Medicare for all.” A public option was seen as the middle ground between the two camps.

“A public option would be a very controversial,” Dr. Whitlock said. Critics say it would pay at Medicare rates, which would reduce doctors’ reimbursements, and save very little money compared with a single-payer system.

Dr. Pearl sees similar problems with lowering the Medicare age. “This would be an expensive change that the federal government could not afford, particularly with all the spending on the pandemic,” he said. “And it would be tough on doctors and hospitals, because Medicare pays less than the private insurance payment they are now getting.”

“The public option is likely to get serious discussion within the Democratic caucus and get onto the Senate floor,” Mr. Levitt said. “The party won’t ignore it.” He notes that in the new Senate, Sen. Sanders chairs the budget committee, and from that position he is likely to push for expanding access to care.

Mr. Levitt says the Biden CMS might allow states to experiment with a statewide public option or even a single-payer model, but he concedes that states, with their budgets ravaged by COVID-19, do not currently have the money to launch such programs.
 

 

 

6. Reviving the CMS

Under President Obama, the CMS was the engine that implemented the ACA and shepherded wider use of value-based reimbursements, which reward providers for quality and outcomes rather than volume.

Under the Trump administration, CMS leadership continued to uphold value-based reimbursement, Dr. Pearl observed. “CMS leadership championed value-based payments, but they encountered a lot of pushback from doctors and hospitals and had to scale back their goals,” he said.

On the other hand, the Trump CMS took a 180-degree turn on the ACA and worked to take it apart. This took a toll on staff morale, according to Donald M. Berwick, MD, who ran the CMS under President Obama. “Many people in CMS did not feel supported during the Trump administration, and some of them left,” Dr. Berwick said.

The CMS needs experienced staff on board to write comprehensible rules and regulations that can overcome court challenges.

Having a fully functioning CMS also requires consistent leadership, which was a problem for Obama. When Mr. Obama nominated Dr. Berwick, 60 Senate votes were needed to confirm him, and Republicans would not vote for him. Mr. Obama eventually brought Dr. Berwick in as a recess appointment, but it meant he could serve for only 17 months.

Since then, Senate confirmation rules have changed so that only a simple majority is needed to confirm appointments. This is important for Biden’s nominees, Dr. Berwick said. “For a president, having your team in place means you are able to execute the policies you want,” he said. “You need to have consistent leadership.”
 

7. Potentially changing health care without Congress

Even with their newly won control of the Senate, the Democrats’ thin majorities in both houses of Congress may not be enough to pass much legislation if Republicans are solidly opposed.

Democrats in the House also have a narrow path this session in which to pass legislation. The Democratic leadership has an 11-vote majority, but it must contend with 15 moderate representatives in purple districts (where Democrats and Republicans have about equal support).

A bigger problem looms before the Democrats. In 2022, the party may well lose its majorities in both houses. Mr. Whitlock notes that the party of an incoming president normally loses seats in the first midterm election. “The last incoming president to keep both houses of Congress in his first midterm was Jimmy Carter,” he said.

If this happens, President Biden would have to govern without the support of Congress, which is what Barack Obama had to do through most of his presidency. As Mr. Obama’s vice president, Mr. Biden is well aware how that goes. Governing without Congress means relying on presidential orders and decrees.

In health care, Mr. Biden has a powerful policy-making tool, the Center for Medicare & Medicaid Innovation (CMMI). The CMMI was empowered by the ACA to initiate pilot programs for new payment models.

So far, the CMMI’s work has been mainly limited to accountable care organizations, bundled payments, and patient-centered medical homes, but it could also be used to enact new federal policies that would normally require Congressional action, Mr. Levitt said.
 

Conclusion

Expectations have been very high for what President Joe Biden can do in health care. He needs to unite a very divided political system to defeat a deadly pandemic, restore Obamacare, and sign landmark legislation, such as a drug-pricing bill.

But shepherding bills through Congress will be a challenge. “You need to have accountability, unity, and civility, which is a Herculean task,” Mr. Whitlock said. “You have to keep policies off the table that could blow up the bipartisanship.”

On receiving the COVID-19 vaccine

This moment, for which I am so grateful and fortunate, represents a link in a remarkable chain of events that spans decades and represents the acme of human achievement.

Dr. Barry Aaronson receives his COVID-19 vaccine.

My gratitude starts with scientists who years before this pandemic, perfected the ability to extract DNA from viruses, sequence it, and transcribe it to RNA. From there my gratitude goes to scientists who years ago developed an ingenious animal model for mRNA vaccines. The next link of gratitude is for scientists who at the start of this year quickly identified a deadly novel coronavirus and to scientists who rapidly sequenced its villainous DNA.

Next, I give thanks to scientists who promptly identified the segment of that DNA that codes for the spike proteins that the virus uses to invade our cells. And then I am grateful to the scientists who made the mRNA that corresponds to that specific DNA sequence, and to the scientists who figured out how create a lipid womb to protect that precious mRNA payload during its perilous journey from factory floor to the depths of our deltoid musculature.

I am no less grateful to the brave people who volunteered for the Pfizer trial, taking the risk of being the first humans ever to participate in an mRNA trial with stakes so high, and to the investigators who ran that trial and the scientists at Pfizer, the Food and Drug Administration, and the Western Coalition who reviewed the data and approved the vaccine without bowing to political pressure.

My gratitude extends to the factory workers who manufactured the vaccine in mass quantities, and the workers who manufactured the equipment that those factories rely on, and the pilots of planes and drivers of trucks who transported the vaccine to my hospital in Seattle, and to the workers who made those planes and trucks that carried that precious cargo. And the workers who devised super-cold storage systems and the workers who built those systems, and the people who fed them and clothed them and housed them so that they could do this life-saving work.

And to the leaders at my hospital who devised our immunization plan, and the ethicists who figured out who should go first (thanks Nancy), and the workers who made the glass vials to hold the vaccine, the plastic syringes to deliver it precisely, and surgically sharp needles so that there would be no pain whatsoever when those beautiful little mRNA filled lipid particles got injected into my left deltoid muscle by a highly skilled and compassionate nurse.

From there, the miracle of nature takes hold causing my cells to transcribe that RNA into spike proteins which will trigger my magical B-cells and T-cells to recognize that nasty spike protein as foreign in case it ever shows its ugly head to my respiratory mucosa, where these cells and the antibodies and chemicals they produce would stomp that wretched virus down without me ever knowing it or missing a beat, and keep me safe not only to live and thrive another day but also hopefully prevent me from spreading the virus to those I love and others I don’t even know but pass within just feet of.

For these miracles of nature and the chain of human toil and genius involving innumerable individuals over many years, many whom will never be thanked or recognized, I am truly and forever grateful.

Limiting antibiotic therapy after surgical drainage for native joint bacterial arthritis

Article Type
Changed
Thu, 01/21/2021 - 12:15

Background: Currently the recommended duration of antibiotic therapy for native joint bacterial arthritis is 3-6 weeks based on expert opinion.

Study design: Prospective, unblinded, randomized, noninferiority.

Setting: Single center in Geneva.

Synopsis: In total, 154 patients were randomized to either 2 weeks or 4 weeks of antibiotic regimen selected in consultation with infectious disease specialists after surgical drainage of native joint bacterial arthritis.

The study population was 38% women with a median age of 51 years. Sites of infection were majority hand and wrist arthritis (64%). The most frequent pathogen was Staphylococcus aureus (31%) with no methicillin-resistant strains. There was a low incidence of patients with bacteremia (4%) and chronic immune compromise (10%). Antibiotic regimen varied with 13 different initial intravenous regimens and 11 different oral regimens.

The primary study outcome was rate of recurrent infection within 2 years, which was low with only one recurrence in the 2-week arm and two recurrences in the 4-week arm. This difference was well within the 10% noninferiority margin selected by the authors.

The study was underpowered for nonhand and nonwrist cases, limiting generalizability.

Bottom line: Consider a shorter duration of antibiotic therapy after surgical drainage for native joint bacterial arthritis of the hand and wrist in an otherwise healthy patient.

The state of inpatient COVID-19 care

Article Type
Changed
Thu, 08/26/2021 - 15:52

A brief evidence-based review of everything we have learned

Evidence on emerging treatments for COVID-19 has been incomplete, often disappointing, and rapidly changing. The concept of a practice-changing press release is as novel as the coronavirus. The pandemic has created an interdependent set of inpatient challenges: keeping up with evolving science and operationalizing clinical workflows, technology, and therapeutics to adapt what we are learning. 

At Dell Medical School, we have created a Therapeutics and Informatics Committee to put evidence into practice in real-time, and below is a brief framework of what we have learned to date:

The COVID-19 disease course can be broken down into 3 stages, and workup and interventions should be targeted to those stages.1–3

Stage 1 is the viral phase following a median 5-day pre-symptomatic phase from exposure; this is indistinguishable from an influenza-like illness with the typical fever, cough, GI symptoms, and the more specific anosmia, ageusia, and orthostasis.

Stage 2 is the pulmonary phase where patients develop COVID-19 pneumonia and will have diffuse chest infiltrates on imaging. This stage usually represents the tail end of the viral phase prior to recovery, but for the ~15% of patients who present to the hospital needing admission because of hypoxemia (the definition of severe COVID-19, typically 5-7 days from symptom onset) this phase is characterized by elevated inflammatory markers and an exuberant host-immune response.

Stage 3 is the dreaded thrombo-inflammatory phase, which is a late manifestation usually >10 days from symptom onset and appears to be independent of viral replication. The morbidity and mortality associated with COVID-19 is likely a result of diffuse microthrombosis, and critical disease should no longer be thought of as a “cytokine storm,” but as life-threatening organ dysfunction caused by a dysregulated host response to infection. Unlike sepsis, the predominant pathology is not vasodilation and shock, but a hypercoagulable state with diffuse endothelial damage.4,5

Workup on presentation to the hospital should focus on identifying which phase of illness the patient is in, based on timing of symptom onset, inflammatory markers, and end-organ damage. CBC, CMP, D-dimer, troponin, and CRP are likely sufficient baseline labs in addition to a chest X-ray. There are many risk stratification tools, but to date, the 4C Mortality 4C Deterioration Scores are recommended due to their large derivation cohort and reliance on only 8 practical variables.6

Dr. W. Michael Brode

Remdesivir and convalescent plasma (CVP) disrupt viral replication in stages 1 and 2 of the illness. Remdesivir has shown efficacy reducing hospital length of stay and a small trend towards decreasing mortality, especially if given within 10 days of symptom onset, although its effectiveness in general use is very small, if it exists at all.7,8 CVP efficacy has been disappointing and should not be the standard of care: multiple RCTs do not show any clinical benefit, although the Mayo Clinic registry data suggests that high-titer CVP given within 3 days from diagnosis decreases mortality compared to low-titer plasma.9-11 Monoclonal antibodies are theoretically “supercharged” high-titer CVP, but are approved for outpatient use only. Trials for hospitalized patients requiring oxygen were stopped due to futility. By the time the patient is hospitalized, it is probably too late in the disease course for CVP or monoclonal antibodies to be effective.

Dexamethasone is the only treatment with a proven mortality benefit. The RECOVERY trial showed the greatest mortality benefit (number needed to treat [NNT] of 8) in mechanically ventilated patients > 7 days from symptom onset. While there is a benefit to patients requiring any oxygen (NNT of 35), early administration to patients in the viral phase is associated with higher mortality as corticosteroids can reduce viral clearance.12 Corticosteroids should therefore be targeted to a therapeutic window to reduce the dysregulated host immune response and treat ARDS in phases 2 and 3; earlier is not necessarily better.

Incidence of venous thromboembolism (VTE) increases linearly with disease severity (one metanalysis showing a rate of 24% in the ICU13) and autopsy studies demonstrate diffuse microthrombosis even when VTE was not suspected5. Observational studies have shown VTE pharmacoprophylaxis reduces mortality, but the optimal agent, timing, and intensity of regimens is not yet clear.14-15 A recent press release from the NIH reported that full dose prophylactic anticoagulation in moderately ill patients reduced disease progression and trended toward lower mortality. Interestingly, for critically ill patients requiring high-flow nasal cannula (HFNC) or mechanical ventilation, intensified anticoagulation regiments had potential harm, and enrollment was stopped in this cohort.16 This announcement is a hopeful sign that intensified anticoagulation regimens can prevent thrombo-inflammation, but until the data of multiple ongoing trials is published it remains expert opinion only.

The most important treatment remains delivering oxygen with fidelity, correcting the much-observed “silent” or “happy hypoxemic.”17 Given the high mortality associated with mechanical ventilation and that hypoxemia can be out of proportion to respiratory distress, arbitrary thresholds should not be used to decide when to intubate and instead should evaluate work of breathing, hypercapnia, mentation, or progression of end-organ damage rather than a single cutoff.18 High-flow nasal cannula (HFNC) can correct severe hypoxemia in addition to self-proning, and while there is scant outcomes data for this strategy, it has been adopted widely as ICU capacity is strained nationally. A ventilator can add PEEP for alveolar recruitment or perform the work of breathing for a patient, but a patient will receive 100% FiO2 whether it is delivered through the nares on HFNC or 10 inches lower by an endotracheal tube.

In the absence of a single therapeutic cure or breakthrough, caring for a COVID-19 patient requires the hospital system to instead do a thousand things conscientiously and consistently. This is supportive care: most patients will get better with time and attentive evaluation for end-organ complications like myocarditis, encephalopathy, or pressure ulcers. It requires nursing to patient ratios that allows for this type of vigilance, with shared protocols, order sets, and close communication among team members that provides this support. The treatment of COVID-19 continues to evolve, but as we confront rising hospital volumes nationally, it is important to standardize care for patients throughout each of the 3 stages of illness until we find that single breakthrough.

Dr. Brode is a practicing internal medicine physician at Dell Seton Medical Center and assistant professor in the Department of Internal Medicine at Dell Medical School, both in Austin, Texas. He is a clinician educator who emphasizes knowing the patient as a person first, evidence-based diagnosis, and comprehensive care for the patients who are most vulnerable.

A brief evidence-based review of everything we have learned

A brief evidence-based review of everything we have learned

Evidence on emerging treatments for COVID-19 has been incomplete, often disappointing, and rapidly changing. The concept of a practice-changing press release is as novel as the coronavirus. The pandemic has created an interdependent set of inpatient challenges: keeping up with evolving science and operationalizing clinical workflows, technology, and therapeutics to adapt what we are learning. 

At Dell Medical School, we have created a Therapeutics and Informatics Committee to put evidence into practice in real-time, and below is a brief framework of what we have learned to date:

The COVID-19 disease course can be broken down into 3 stages, and workup and interventions should be targeted to those stages.1–3

Stage 1 is the viral phase following a median 5-day pre-symptomatic phase from exposure; this is indistinguishable from an influenza-like illness with the typical fever, cough, GI symptoms, and the more specific anosmia, ageusia, and orthostasis.

Stage 2 is the pulmonary phase where patients develop COVID-19 pneumonia and will have diffuse chest infiltrates on imaging. This stage usually represents the tail end of the viral phase prior to recovery, but for the ~15% of patients who present to the hospital needing admission because of hypoxemia (the definition of severe COVID-19, typically 5-7 days from symptom onset) this phase is characterized by elevated inflammatory markers and an exuberant host-immune response.

Stage 3 is the dreaded thrombo-inflammatory phase, which is a late manifestation usually >10 days from symptom onset and appears to be independent of viral replication. The morbidity and mortality associated with COVID-19 is likely a result of diffuse microthrombosis, and critical disease should no longer be thought of as a “cytokine storm,” but as life-threatening organ dysfunction caused by a dysregulated host response to infection. Unlike sepsis, the predominant pathology is not vasodilation and shock, but a hypercoagulable state with diffuse endothelial damage.4,5

Workup on presentation to the hospital should focus on identifying which phase of illness the patient is in, based on timing of symptom onset, inflammatory markers, and end-organ damage. CBC, CMP, D-dimer, troponin, and CRP are likely sufficient baseline labs in addition to a chest X-ray. There are many risk stratification tools, but to date, the 4C Mortality 4C Deterioration Scores are recommended due to their large derivation cohort and reliance on only 8 practical variables.6

Dr. W. Michael Brode

Remdesivir and convalescent plasma (CVP) disrupt viral replication in stages 1 and 2 of the illness. Remdesivir has shown efficacy reducing hospital length of stay and a small trend towards decreasing mortality, especially if given within 10 days of symptom onset, although its effectiveness in general use is very small, if it exists at all.7,8 CVP efficacy has been disappointing and should not be the standard of care: multiple RCTs do not show any clinical benefit, although the Mayo Clinic registry data suggests that high-titer CVP given within 3 days from diagnosis decreases mortality compared to low-titer plasma.9-11 Monoclonal antibodies are theoretically “supercharged” high-titer CVP, but are approved for outpatient use only. Trials for hospitalized patients requiring oxygen were stopped due to futility. By the time the patient is hospitalized, it is probably too late in the disease course for CVP or monoclonal antibodies to be effective.

Dexamethasone is the only treatment with a proven mortality benefit. The RECOVERY trial showed the greatest mortality benefit (number needed to treat [NNT] of 8) in mechanically ventilated patients > 7 days from symptom onset. While there is a benefit to patients requiring any oxygen (NNT of 35), early administration to patients in the viral phase is associated with higher mortality as corticosteroids can reduce viral clearance.12 Corticosteroids should therefore be targeted to a therapeutic window to reduce the dysregulated host immune response and treat ARDS in phases 2 and 3; earlier is not necessarily better.

Incidence of venous thromboembolism (VTE) increases linearly with disease severity (one metanalysis showing a rate of 24% in the ICU13) and autopsy studies demonstrate diffuse microthrombosis even when VTE was not suspected5. Observational studies have shown VTE pharmacoprophylaxis reduces mortality, but the optimal agent, timing, and intensity of regimens is not yet clear.14-15 A recent press release from the NIH reported that full dose prophylactic anticoagulation in moderately ill patients reduced disease progression and trended toward lower mortality. Interestingly, for critically ill patients requiring high-flow nasal cannula (HFNC) or mechanical ventilation, intensified anticoagulation regiments had potential harm, and enrollment was stopped in this cohort.16 This announcement is a hopeful sign that intensified anticoagulation regimens can prevent thrombo-inflammation, but until the data of multiple ongoing trials is published it remains expert opinion only.

The most important treatment remains delivering oxygen with fidelity, correcting the much-observed “silent” or “happy hypoxemic.”17 Given the high mortality associated with mechanical ventilation and that hypoxemia can be out of proportion to respiratory distress, arbitrary thresholds should not be used to decide when to intubate and instead should evaluate work of breathing, hypercapnia, mentation, or progression of end-organ damage rather than a single cutoff.18 High-flow nasal cannula (HFNC) can correct severe hypoxemia in addition to self-proning, and while there is scant outcomes data for this strategy, it has been adopted widely as ICU capacity is strained nationally. A ventilator can add PEEP for alveolar recruitment or perform the work of breathing for a patient, but a patient will receive 100% FiO2 whether it is delivered through the nares on HFNC or 10 inches lower by an endotracheal tube.

In the absence of a single therapeutic cure or breakthrough, caring for a COVID-19 patient requires the hospital system to instead do a thousand things conscientiously and consistently. This is supportive care: most patients will get better with time and attentive evaluation for end-organ complications like myocarditis, encephalopathy, or pressure ulcers. It requires nursing to patient ratios that allows for this type of vigilance, with shared protocols, order sets, and close communication among team members that provides this support. The treatment of COVID-19 continues to evolve, but as we confront rising hospital volumes nationally, it is important to standardize care for patients throughout each of the 3 stages of illness until we find that single breakthrough.

He is a clinician educator who emphasizes knowing the patient as a person first, evidence-based diagnosis, and comprehensive care for the patients who are most vulnerable.

President Biden kicks off health agenda with COVID actions, WHO outreach

Article Type
Changed
Thu, 08/26/2021 - 15:52

 

President Joe Biden kicked off his new administration Jan. 20 with an immediate focus on attempts to stop the spread of COVID-19, including closer coordination with other nations.

Mr. Biden signed 17 executive orders, memoranda, and directives addressing not only the pandemic but also economic concerns, climate change, and racial inequity.

At the top of the list of actions was what his transition team called a “100 Days Masking Challenge.” Mr. Biden issued an executive order requiring masks and physical distancing in all federal buildings, on all federal lands, and by federal employees and contractors.

The president also halted the Trump administration’s process of withdrawing from the World Health Organization. Instead, Mr. Biden named Anthony Fauci, MD, the director of the National Institute for Allergy and Infectious Diseases, as the head of a delegation to participate in the WHO executive board meeting that is being held this week.

Mr. Biden also signed an executive order creating the position of COVID-19 response coordinator, which will report directly to the president and be responsible for coordinating all elements of the COVID-19 response across government, including the production and distribution of vaccines and medical supplies.

The newly inaugurated president also intends to restore the National Security Council’s Directorate for Global Health Security and Biodefense, which will aid in the response to the pandemic, his transition team said.

The American Medical Association was among the first to commend the first-day actions.

“Defeating COVID-19 requires bold, coordinated federal leadership and strong adherence to the public health steps we know stop the spread of this virus – wearing masks, practicing physical distancing, and washing hands,” said AMA President Susan R. Bailey, MD in a news release. “We are pleased by the Biden administration’s steps today, including universal mask wearing within federal jurisdictions, providing federal leadership for COVID-19 response, and reengaging with the World Health Organization. Taking these actions on day 1 of the administration sends the right message – that our nation is laser focused on stopping the ravages of COVID-19.”

COVID-19 may damage blood vessels in the brain

Article Type

Thu, 08/26/2021 - 15:52

Until now, the neurological manifestations of COVID-19 have been believed to be a result of direct damage to nerve cells. However, a new study suggests that the virus might actually damage the brain’s small blood vessels rather than nerve cells themselves.

A postmortem analysis found abnormalities in the brains of a small sample of patients with COVID-19, suggesting inflammation and vascular damage to the brain stem and olfactory bulb. The findings add further weight to previous research into neurological complications from COVID-19, according to Anna Cervantes, MD. Dr. Cervantes is assistant professor of neurology at the Boston University and has been studying the neurological effects of COVID-19, though she was not involved in this study. “I can tell from my personal experience, and things we’ve published on and the literature that’s out there – there are patients that are having complications like stroke that aren’t even critically ill from COVID. We’re seeing that not in just the acute setting, but also in a delayed fashion. Even though most of the coagulopathy is largely venous and probably microvascular, this does affect the brain through a myriad of ways,” Dr. Cervantes said.

The research was published online Jan. 12 in the New England Journal of Medicine. Myoung‑Hwa Lee, PhD, was the lead author.

The study included high resolution magnetic resonance imaging and histopathological examination of 13 individuals with a median age of 50 years. Among 10 patients with brain alterations, the researchers conducted further studies in 5 individuals using multiplex fluorescence imaging and chromogenic immunostaining in all 10.

The team conducted conventional histopathology on the brains of 18 individuals. Fourteen had a history of chronic illness, including diabetes, and hypertension, and 11 had died unexpectedly or been found dead. Magnetic resonance microscopy revealed punctuate hypo-intensities in nine subjects, indicating microvascular injury and fibrinogen leakage. Histopathology using fluorescence imaging showed the same features. Collagen IV immunostaining showed thinning of the basal lamina of the endothelial cells in five patients. Ten patients had congested blood vessels and surrounding fibrinogen leakage, but comparatively intact vasculature. The researchers interpreted linear hypo-intensities as micro-hemorrhages.

The researchers found little perivascular inflammation, and no vascular occlusion. Thirteen subjects had perivascular-activated microglia, macrophage infiltrates, and hypertrophic astrocytes. Eight had CD3+ and CD8+ T cells in the perivascular spaces and in lumens next to endothelial cells, which could help explain vascular injury.

The researchers found no evidence of the SARS-CoV-2 virus itself, despite efforts using polymerase chain reaction with multiple primer sets, RNA sequencing within the brain, or RNA in situ hybridization and immunostaining. Subjects may have cleared the virus by the time they died, or viral copy numbers could have been below the detection limit of the assays.

The researchers also obtained a convenience sample of subjects who had died from COVID-19. Magnetic resonance microscopy, histopathology, and immunohistochemical analysis of sections revealed microvascular injury in the brain and olfactory bulb, despite no evidence of viral infection. The authors stressed that they could not draw conclusions about the neurological features of COVID-19 because of a lack of clinical information.

Dr. Cervantes noted that limitation: “We’re seeing a lot of patients with encephalopathy or alterations in their mental status. A lot of things can cause that, and some are common in patients who are critically ill, like medications and metabolic derangement.”

Still, the findings could help to inform future medical management. “There’s going to be a large number of patients who don’t have really bad pulmonary disease but still may have encephalopathy. So if there is small vessel involvement because of inflammation that we might not necessarily catch in a lumbar puncture or routine imaging, there’s still somebody we can make better (using) steroids. Having more information on what’s happening on a pathophysiologic level and on pathology is really helpful.”

The study was supported by internal funds from the National Institute of Neurological Disorders and Stroke. Dr. Cervantes has no relevant financial disclosures.

Until now, the neurological manifestations of COVID-19 have been believed to be a result of direct damage to nerve cells. However, a new study suggests that the virus might actually damage the brain’s small blood vessels rather than nerve cells themselves.
