“Chronic HBV coinfection is common among people with HIV, but the determinants of HBV-associated HCC are not well characterized,” said presenter H. Nina Kim MD, MSc, of the University of Washington, Seattle. “We sought to identify factors that contribute to HCC development in persons with HIV/HBV coinfection to guide early detection and prevention measures.”

The researchers conducted a longitudinal cohort study within the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), a collaboration of single-site and multisite cohorts throughout the United States and Canada; 22 cohorts from NA-ACCORD were included in the analysis.

Potential HIV and HBV risk factors were examined, including viremia and CD4 percentage, as well as HBV DNA levels. Traditional risk factors for liver disease progression, including age, sex, and heavy alcohol use, were also assessed.

Eligible patients were 18 years of age or older who were followed for at least 6 months, had evidence of chronic HBV, and had HIV RNA or CD4+ cell measurement during this period. Persons with prevalent HCC at baseline were excluded.

The primary outcome was first occurrence of HCC, which was adjudicated by medical chart review and/or cancer registry. Multivariable Cox regression was used to determine adjusted hazard ratios of risk factors.
 

Results

Among 9,383 HIV/HBV-coinfected individuals identified, 8,354 (89%) were included in the analysis. The median age of participants was 43 years and 93.1% were male. Heavy alcohol use (35.3%) and chronic hepatitis C virus (HCV) coinfection (21.6%) were common among participants.

Among 8,354 eligible participants, 115 developed HCC over a median 6.9 years of follow-up (incidence rate, 1.8 events per 1,000 person-years; 95% confidence interval [CI], 1.5-2.1).

Independent risk factors for HCC were chronic HCV coinfection (adjusted hazard ratio [aHR], 1.60 [95% confidence interval, 1.07-2.39]), age 40 years and older (aHR, 2.14 [1.36-3.37]), and heavy alcohol use (aHR, 1.51 [1.03-2.21]); however, time-updated CD4+ percentage less than 14% (aHR, 1.03 [0.56-1.90]) and time-updated HIV RNA level over 500 copies/mL (aHR, 0.88 [0.55-1.41]) were not associated with HCC risk.

In a second model, among 3,054 patients who had HBV DNA measured, the risk of HCC was higher with HBV DNA levels greater than 200 IU/mL (aHR, 2.70 [1.23-5.93]), and the risk was particularly elevated at levels greater than 200,000 IU/mL (aHR, 4.34 [1.72-10.94]).

The researchers also found that the risk of HCC was significantly lower in patients with HBV DNA suppression less than 200 IU/mL receiving HBV-active ART for 1 year or more (aHR, 0.42 [0.24-0.73]). In addition, a dose-response relationship was observed between the duration of suppression and this protective effect.

Dr. Nina Kim acknowledged that a key limitation of the study was inconsistent monitoring of HBV DNA level while patients were on treatment. Furthermore, given the demographics of the cohort, these results may not be generalizable outside of North America.

“Our study was the first to show that any level of HBV viremia using 200 as a threshold of detection was associated with HCC risk in a large regionally diverse cohort of adults outside of Asia,” Dr. Kim said. “To gain maximal protective benefit from antiviral therapy for HCC prevention, sustained and ideally uninterrupted suppression of HBV may be necessary over years.”

“HIV/HBV coinfected patients can take much longer than a year to achieve less than 200 copies on HBV DNA due to their baseline levels, but we still don’t know if HBV therapy intensification could hasten this process,” said moderator Robert T. Schooley, MD, of the University of California, San Diego.

Dr. Kim disclosed no conflicts of interest. The study was supported by multiple sources, including the National Institutes of Health, the Centers for Disease Control and Prevention, and the National Cancer Institute.

MYTH: I shouldn’t get the vaccine because of potential long-term side effects

We know that 68 million people in the United States and 244 million people worldwide have already received messenger RNA (mRNA) SARS-CoV-2 vaccines (Pfizer/BioNTech and Moderna). So for the short-term side effects we already know more than we would know about most vaccines.

What about the long-term side effects? There are myths that these vaccines somehow could cause autoimmunity. This came from three publications where the possibility of mRNA vaccines to produce autoimmunity was brought up as a discussion point.^1-3 There was no evidence given in these publications, it was raised only as a hypothetical possibility.

There’s no evidence that mRNA or replication-defective DNA vaccines (AstraZeneca/Oxford and Johnson & Johnson) produce autoimmunity. Moreover, the mRNA and replication-defective DNA, once it’s inside of the muscle cell, is gone within a few days. What’s left after ribosome processing is the spike (S) protein as an immunogen. We’ve been vaccinating with proteins for 50 years and we haven’t seen autoimmunity.
 

MYTH: The vaccines aren’t safe because they were developed so quickly

These vaccines were developed at “warp speed” – that doesn’t mean they were developed without all the same safety safeguards that the Food and Drug Administration requires. The reason it happened so fast is because the seriousness of the pandemic allowed us, as a community, to enroll the patients into the studies fast. In a matter of months, we had all the studies filled. In a normal circumstance, that might take 2 or 3 years. And all of the regulatory agencies – the National Institutes of Health, the FDA, the Centers for Disease Control and Prevention – were ready to take the information and put a panel of specialists together and immediately review the data. No safety steps were missed. The same process that’s always required of phase 1, of phase 2, and then at phase 3 were accomplished.

The novelty of these vaccines was that they could be made so quickly. Messenger RNA vaccines can be made in a matter of days and then manufactured in a matter of 2 months. The DNA vaccines has a similar timeline trajectory.
 

MYTH: There’s no point in getting the vaccines because we still have to wear masks

Right now, out of an abundance of caution, until it’s proven that we don’t have to wear masks, it’s being recommended that we do so for the safety of others. Early data suggest that this will be temporary. In time, I suspect it will be shown that, after we receive the vaccine, it will be shown that we are not contagious to others and we’ll be able to get rid of our masks.

MYTH: I already had COVID-19 so I don’t need the vaccine

Some people have already caught the SARS-CoV-2 virus that causes this infection and so they feel that they’re immune and they don’t need to get the vaccine. Time will tell if that’s the case. Right now, we don’t know for sure. Early data suggest that a single dose of vaccine in persons who have had the infection may be sufficient. Over time, what happens in the vaccine field is we measure the immunity from the vaccine, and from people who’ve gotten the infection, and we find that there’s a measurement in the blood that correlates with protection. Right now, we don’t know that correlate of protection level. So, out of an abundance of caution, it’s being recommended that, even if you had the disease, maybe you didn’t develop enough immunity, and it’s better to get the vaccine than to get the illness a second time.

MYTH: The vaccines can give me SARS-CoV-2 infection

The new vaccines for COVID-19, released under emergency use Authorization, are mRNA and DNA vaccines. They are a blueprint for the Spike (S) protein of the virus. In order to become a protein, the mRNA, once it’s inside the cell, is processed by ribosomes. The product of the ribosome processing is a protein that cannot possibly cause harm as a virus. It’s a little piece of mRNA inside of a lipid nanoparticle, which is just a casing to protect the mRNA from breaking down until it’s injected in the body. The replication defective DNA vaccines (AstraZeneca/Oxford and Johnson & Johnson) are packaged inside of virus cells (adenoviruses). The DNA vaccines involve a three-step process:

• 1. The adenovirus, containing replication-defective DNA that encodes mRNA for the Spike (S) protein, is taken up by the host cells where it must make its way to the nucleus of the muscle cell.
• 2. The DNA is injected into the host cell nucleus and in the nucleus the DNA is decoded to an mRNA.
• 3. The mRNA is released from the nucleus and transported to the cell cytoplasm where the ribosomes process the mRNA in an identical manner as mRNA vaccines.

MYTH: The COVID-19 vaccines can alter my DNA

The mRNA and replication-defective DNA vaccines never interact with your DNA. mRNA vaccines never enter the nucleus. Replication-defective DNA vaccines cannot replicate and do not interact with host DNA. The vaccines can’t change your DNA.

Here is a photo of me receiving my first SARS-CoV-2 shot (Moderna) in January 2021. I received my second shot in February. I am a lot less anxious. I hope my vaccine card will be a ticket to travel in the future.

Skin microbiome therapy to protect against Staphylococcus aureus in patients with atopic dermatitis (AD) proved safe in a phase 1 randomized clinical trial that also demonstrated “encouraging clinical and mechanistic results,” Richard L. Gallo, MD, PhD, and his coinvestigators have reported in Nature Medicine.

Findings from the 1-week, 54-patient trial of a topical formulation containing Staphylococcus hominis A9 (ShA9) offer evidence that the strain directly kills S. aureus, inhibits the production of S. aureus–generated toxins, and enables expansion of a healthy bacterial community, “allowing the rest of the microbiome to start to recover to normal,” Dr. Gallo, professor and chairman of the department of dermatology at the University of California, San Diego, said in an interview.

“And perhaps most exciting,” Dr. Gallo added, is the finding that the subset of patients with AD who were most responsive to the ShA9 compound – approximately two-thirds of the participants who were randomized to receive it – showed improvement in local EASI (Eczema Area and Severity Index) and SCORAD (Scoring Atopic Dermatitis) scores used to assess inflammation. Plans are underway for a larger and longer trial, he said.

S. aureus commonly colonizes patients with AD and exacerbates disease by causing inflammation. In recent years, Dr. Gallo and other investigators have come to believe that AD is a cyclic disease in which the skin’s microbiome affects the host, and the host affects the microbiome. The goal of bacteriotherapy is to break the cycle of S. aureus colonization and improve the skin immune and barrier dysfunction characteristics of AD, Dr. Gallo said.

ShA9, a bacterium isolated from healthy human skin, was chosen as a potential topical therapy for AD based on its capacity both to selectively kill S. aureus and to inhibit toxin production by S. aureus. Dr. Gallo’s team’s preclinical work involved screening thousands of isolates of coagulase-negative staphylococci for gene products that perform these two functions by expressing both antimicrobial peptides (AMPs) and autoinducing peptides (AIPs), the latter of which inhibit the S. aureus quorum-sending system that leads to toxin production. Most patients with AD lack protective strains of coagulase-negative staphylococci, including S. hominis, prior research has found.

The double-blind phase 1 trial randomized 54 adults with moderate-severe AD affecting the ventral forearms in a 2:1 fashion to receive the proprietary lyophilized preparation of ShA9 or an ShA9-free formulation twice daily for 1 week. All participants were culture positive for S. aureus.

Clinical assessments and skin swabs were obtained before and within an hour after the first application of day 1, and swabs were collected on days 4 and 7 within 4 hours of the first application.

Blinded physician assessments and skin swabs were also obtained at 24, 48, and 96 hours after the final dose on day 7.

Based on structured daily diaries, there were no serious adverse events, and significantly fewer adverse events in those treated with ShA9, compared with the vehicle alone; 55.6% versus 83.3%, respectively, were considered to have adverse events.

The adverse event–reporting system captured the normal fluctuation of eczema and considered any report of fluctuation above baseline to be an adverse event. “Patients treated with the [placebo formulation] had the expected high frequency of itching, burning, and pain that you see with AD but it was encouraging that the frequency of reporting these events was significantly less in those treated with the active [formulation],” Dr. Gallo said in the interview.

Their report describes a decrease in S. aureus in participants treated with ShA9, and increases in ShA9 DNA. Not all S. aureus strains were directly killed by ShA9, but all strains had reduced expression of mRNA for psm-alpha, an important virulence factor. That reduced expression correlated with ShA9 AIPs and improved EASI scores, the latter of which was observed in a post-hoc analysis. “Participants with S. aureus not killed by ShA9 were still sensitive to inhibition of toxin production, a mechanistic outcome that predicted clinical improvement in mice and may require longer therapy to observe clinical improvement in humans,” the investigators wrote.

Local eczema severity was not significantly different between the bacteriotherapy and control groups. But the post-hoc analysis showed that after 7 days of treatment, and up to 4 days after treatment was discontinued, the patients with S. aureus that was sensitive to killing by ShA9 (21 out of 35 total who received the bacteriotherapy) showed improvement in EASI and SCORAD scores, compared with control patients.

Future research will assess the compound in both S. aureus culture-positive and culture-negative patients, and in patients with mild disease, Dr. Gallo said.

The trial was conducted at USCD and the National Jewish Health General Clinical Research Center in Denver, and was sponsored by the National Institute of Allergy and Infectious Diseases. The ShA9 formulation and related technology are licensed to MatriSys Bioscience, of which Dr. Gallo is the cofounder and an advisory board member. Dr. Gallo holds equity interest in the company.

Skin microbiome therapy to protect against Staphylococcus aureus in patients with atopic dermatitis (AD) proved safe in a phase 1 randomized clinical trial that also demonstrated “encouraging clinical and mechanistic results,” Richard L. Gallo, MD, PhD, and his coinvestigators have reported in Nature Medicine.

Findings from the 1-week, 54-patient trial of a topical formulation containing Staphylococcus hominis A9 (ShA9) offer evidence that the strain directly kills S. aureus, inhibits the production of S. aureus–generated toxins, and enables expansion of a healthy bacterial community, “allowing the rest of the microbiome to start to recover to normal,” Dr. Gallo, professor and chairman of the department of dermatology at the University of California, San Diego, said in an interview.

“And perhaps most exciting,” Dr. Gallo added, is the finding that the subset of patients with AD who were most responsive to the ShA9 compound – approximately two-thirds of the participants who were randomized to receive it – showed improvement in local EASI (Eczema Area and Severity Index) and SCORAD (Scoring Atopic Dermatitis) scores used to assess inflammation. Plans are underway for a larger and longer trial, he said.

S. aureus commonly colonizes patients with AD and exacerbates disease by causing inflammation. In recent years, Dr. Gallo and other investigators have come to believe that AD is a cyclic disease in which the skin’s microbiome affects the host, and the host affects the microbiome. The goal of bacteriotherapy is to break the cycle of S. aureus colonization and improve the skin immune and barrier dysfunction characteristics of AD, Dr. Gallo said.

ShA9, a bacterium isolated from healthy human skin, was chosen as a potential topical therapy for AD based on its capacity both to selectively kill S. aureus and to inhibit toxin production by S. aureus.

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.

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.

“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.

A third COVID-19 vaccine is now in circulation and states are starting to drop mask mandates, but the latest decline in weekly child cases barely registers as a decline, according to new data from the American Academy of Pediatrics and the Children’s Hospital Association.

The number of new COVID-19 cases in children fell from 64,264 (Feb. 19-25) to 63,562 (Feb. 26 to March 4). That’s only 702 cases – a drop of just 1.1% – the smallest by far since weekly cases peaked in mid-January, the AAP and CHA said in their weekly COVID-19 report. Since that peak, the last 7 weeks of declines have looked like this: 21.7%, 15.3%, 16.2%, 15.7%, 28.7%, 9.0%, and 1.1%.

Meanwhile, children’s share of the COVID-19 burden increased to its highest point ever: 18.0% of all new cases occurred in children during the week ending March 4, climbing from 15.7% the week before and eclipsing the previous high of 16.9%. Cumulatively, the 3.23 million cases in children represent 13.2% of all COVID-19 cases reported in 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

At the state level, the new leader in cumulative share of cases is Vermont at 19.4%, which just edged past Wyoming’s 19.3% as of the week ending March 4. The other states above 18% are Alaska (19.2%) and South Carolina (18.2%). The lowest rates can be found in Florida (8.1%), New Jersey (10.2%), Iowa (10.4%), and Utah (10.5%), the AAP and CHA said.

The overall rate of COVID-19 cases nationwide was 4,294 cases per 100,000 children as of March 4, up from 4,209 per 100,000 the week before. That measure had doubled between Dec. 3 (1,941 per 100,000) and Feb. 4 (3,899) but has only risen about 10% in the last month, the AAP/CHA data show.

Perhaps the most surprising news of the week involves the number of COVID-19 deaths in children, which went from 256 the previous week to 253 after Ohio made a downward revision of its mortality data. So far, children represent just 0.06% of all coronavirus-related deaths, a figure that has held steady since last summer in the 43 states (along with New York City and Guam) that are reporting mortality data by age, the AAP and CHA said.

Hundreds of thousands of deaths worldwide from COVID-19 could have been avoided if obesity rates were lower, a new report says.

An analysis by the World Obesity Federation found that of the 2.5 million COVID-19 deaths reported by the end of February 2021, almost 90% (2.2 million) were in countries where more than half the population is classified as overweight.

The report, released to coincide with World Obesity Day, calls for obesity to be recognized as a disease in its own right around the world, and for people with obesity to be included in priority lists for COVID-19 testing and vaccination.

“Overweight is a highly significant predictor of developing complications from COVID-19, including the need for hospitalization, for intensive care and for mechanical ventilation,” the WOF notes in the report.

It adds that in countries where less than half the adult population is classified as overweight (body mass index > 25 mg/kg²), for example, Vietnam, the likelihood of death from COVID-19 is a small fraction – around one-tenth – of the level seen in countries where more than half the population is classified as overweight.

And while it acknowledges that figures for COVID-19 deaths are affected by the age structure of national populations and a country’s relative wealth and reporting capacity, “our findings appear to be independent of these contributory factors. Furthermore, other studies have found that overweight remains a highly significant predictor of the need for COVID-19 health care after accounting for these other influences.”

As an example, based on the U.K. experience, where an estimated 36% of COVID-19 hospitalizations have been attributed to lack of physical activity and excess body weight, it can be suggested that up to a third of the costs – between $6 trillion and $7 trillion over the longer period – might be attributable to these predisposing risks.

The report said the prevalence of obesity in the United Kingdom is expected to rise from 27.8% in 2016 to more than 35% by 2025.

Rachel Batterham, lead adviser on obesity at the Royal College of Physicians, commented: “The link between high levels of obesity and deaths from COVID-19 in the U.K. is indisputable, as is the urgent need to address the factors that lead so many people to be living with obesity.

“With 30% of COVID-19 hospitalizations in the U.K. directly attributed to overweight and obesity, and three-quarters of all critically ill patients having overweight or obesity, the human and financial costs are high.”
 

Window of opportunity to prioritize obesity as a disease

WOF says that evolving evidence on the close association between COVID-19 and underlying obesity “provides a new urgency … for political and collective action.”

“Obesity is a disease that does not receive prioritization commensurate with its prevalence and impact, which is rising fastest in emerging economies. It is a gateway to many other noncommunicable diseases and mental-health illness and is now a major factor in COVID-19 complications and mortality.”

The WOF also shows that COVID-19 is not a special case, noting that several other respiratory viruses lead to more severe consequences in people living with excess bodyweight, giving good reasons to expect the next pandemic to have similar effects. “For these reasons we need to recognize overweight as a major risk factor for infectious diseases including respiratory viruses.”

“To prevent pandemic health crises in future requires action now: we call on all readers to support the World Obesity Federation’s call for stronger, more resilient economies that prioritize investment in people’s health.”

There is, it stresses, “a window of opportunity to advocate for, fund and implement these actions in all countries to ensure better, more resilient and sustainable health for all, “now and in our postCOVID-19 future.”

It proposes a ROOTS approach:

• Recognize that obesity is a disease in its own right.
• Obesity monitoring and surveillance must be enhanced.
• Obesity prevention strategies must be developed.
• Treatment of obesity.
• Systems-based approaches should be applied.

Despite recent advances in the diagnosis, treatment, and prevention of pediatric tuberculosis in children living with HIV (CLHIV) and HIV-exposed uninfected children (HEU), several unmet needs remain, including studies evaluating the feasibility of shortened TB treatment regimens.

“Children living with HIV contribute disproportionately to pediatric TB mortality rates, accounting for 16% of child TB deaths, and many cases are underdiagnosed and underreported,” said Nicole Salazar-Austin, MD, of Johns Hopkins University in Baltimore. She provided an update on pediatric TB prevention and treatment during an educational symposium at this year’s virtual Conference on Retroviruses & Opportunistic Infections.

Dr. Salazar-Austin summarized current diagnostics for pediatric TB and reviewed options for the prevention and treatment of TB in CLHIV and HEU.
 

TB and CLHIV

Presently, TB is the most common opportunistic infection among CLHIV, and those with severe immune suppression have a fivefold greater risk of TB disease. While antiretroviral therapy (ART) is highly protective against TB disease in CLHIV, only about 50% of eligible children receive ART.

Dr. Salazar-Austin explained that many individuals with TB/HIV coinfection are unaware of their coinfection and not receiving treatment. Despite recommendations, TB preventive therapy is poorly implemented in CLHIV, especially in high-burden settings.
 

Pediatric TB diagnosis

Smear microscopy, culture, and Xpert MTB/RIF Ultra are the main diagnostic modalities for pediatric TB. The Xpert MTB/RIF test is an automated PCR-based assay that simultaneously and rapidly detects Mycobacterium tuberculosis complex and resistance to rifampin. The test is currently recommended by the World Health Organization as the initial diagnostic method for presumptive TB cases in both adults and children.

However, under optimal conditions, only 40% of TB cases will be detected. This is in part due to limited implementation of sputum collection procedures, but recent evidence has shown that collection of multiple specimens improves sensitivity for both culture and Xpert MTB/RIF Ultra across all specimen types, Dr. Salazar-Austin explained.

In 2020, the WHO endorsed the use of stool samples for the diagnosis of pediatric pulmonary TB. Stool Xpert is an emerging alternative, noninvasive method for ruling in pediatric TB disease, and has shown sensitivity and specificity similar to that of Xpert MTB/RIF Ultra.

“TB diagnostics have limited sensitivity in children, and efforts are ongoing to maximize current diagnostics, but new diagnostics are needed,” said Dr. Salazar-Austin.
 

Pediatric TB treatment

Despite the high frequency of TB as an opportunistic infection in CLHIV, current data on co-treatment strategies are limited.

Dolutegravir-based regimens are the preferred first-line regimen for CLHIV. In June 2020, the Food and Drug Administration approved the dispersible dolutegravir tablet, and it is expected to become widely available in 2021.

In children with TB/HIV coinfection who receive dolutegravir and rifampicin, dolutegravir is typically dosed twice daily because of a known drug interaction, based on data from the ODYSSEY study. The WHO recommendations for treatment of pediatric TB/HIV coinfection were recently updated to reflect twice-daily dosing of dolutegravir.

Despite these new recommendations, data are currently limited, and observational pharmacokinetic studies evaluating twice daily dolutegravir with TB treatment in young children are needed.

“More work is needed to evaluate the drug-drug interactions and proper dosing of rifamycins with dolutegravir for the treatment and prevention of TB in CLHIV,” Dr. Salazar-Austin said.

Based on data from TBTC Study 31/ACTG A5349, high-dose rifapentine (a rifamycin) with moxifloxacin (a fluoroquinolone) was noninferior to rifapentine alone in newly diagnosed, culture positive, drug-susceptible TB in children 12 years and older.

Whether rifapentine and moxifloxacin (RPT-Mox) can be used in children under 12 years remains unknown, but future studies may help answer this question, Dr. Salazar-Austin noted. The FDA has restricted the use of fluoroquinolones in children because of a possible effect on cartilage development, she explained.

Furthermore, recent data from the SHINE trial suggested that shortened treatment regimens may hold promise for children with TB.

“While shortened TB treatment regimens hold promise, much work needs to be done in children to implement RPT-Mox, but the results from SHINE can be implemented rapidly,” Dr. Salazar-Austin said.

Dr. Salazar-Austin disclosed no conflicts of interest. The presentation was funded by NICHD, UNITAID, Fogarty Institute, and the IMPAACT network.

Despite these new recommendations, data are currently limited, and observational pharmacokinetic studies evaluating twice daily dolutegravir with TB treatment in young children are needed.

“More work is needed to evaluate the drug-drug interactions and proper dosing of rifamycins with dolutegravir for the treatment and prevention of TB in CLHIV,” Dr. Salazar-Austin said.

Based on data from TBTC Study 31/ACTG A5349, high-dose rifapentine (a rifamycin) with moxifloxacin (a fluoroquinolone) was noninferior to rifapentine alone in newly diagnosed, culture positive, drug-susceptible TB in children 12 years and older.

Whether rifapentine and moxifloxacin (RPT-Mox) can be used in children under 12 years remains unknown, but future studies may help answer this question, Dr. Salazar-Austin noted. The FDA has restricted the use of fluoroquinolones in children because of a possible effect on cartilage development, she explained.

Furthermore, recent data from the SHINE trial suggested that shortened treatment regimens may hold promise for children with TB.

“While shortened TB treatment regimens hold promise, much work needs to be done in children to implement RPT-Mox, but the results from SHINE can be implemented rapidly,” Dr. Salazar-Austin said.

Dr. Salazar-Austin disclosed no conflicts of interest. The presentation was funded by NICHD, UNITAID, Fogarty Institute, and the IMPAACT network.

Long-acting injectable (LAI) drug formulations represent a promising new strategy for the prevention and treatment of tuberculosis in women and children, according to an online presentation at the Conference on Retroviruses & Opportunistic Infections, held virtually.

“As a delivery strategy, LAIs hold the potential to unlock a vast chemical space of lipophilic compounds with very potent anti-TB activity that would otherwise not be developed due to poor predicted oral bioavailability,” explained presenter Eric Nuermberger, MD.

He summarized current preventive treatment options for TB and reviewed the potential impact of LAI formulations on TB therapy. In addition, he identified key challenges for future LAI development and proposed a new development path for clinical implementation.
 

Current TB preventive therapies

Despite widespread availability, the uptake of TB preventive therapy is poor and currently lags behind global targets. One key barrier to widespread uptake is the long duration of treatment, which may hinder patient adherence to therapy.

While shorter preventive regimens, such as 1 month of daily isoniazid plus rifapentine, show similar efficacy and higher completion rates, further shortening of therapy and reducing clinic visits are the most direct methods to increase adherence and treatment completion rates, Dr. Nuermberger said.
 

LAI drugs

LAI drug formulations allow for slow release of suitable drugs from a depot injected subcutaneously or intramuscularly.

The goal of LAI formulations is to free patients from the daily burden of oral administration. Other potential benefits include better adherence and efficacy, drug exposure, and the potential to overcome intrinsic poor oral bioavailability by bypassing the GI tract entirely.

Potential indications for LAIs include treatment of latent tuberculosis infection (LTBI), and as continuous therapy in people living with HIV in high-burden settings. There is also potential for treating younger children, such as household contacts, who have difficulty taking oral medications.

“We’ve already seen LAIs revolutionize other areas, such as psychiatry and contraception, and we appear to have another revolution in HIV prevention and treatment,” Dr. Nuermberger explained.

Not all existing TB drugs are suitable for LAI formulations, but drugs such as rifapentine, rifabutin, delamanid, and bedaquiline, show more promise than isoniazid or rifampin because of their physiochemical composition. Of all, bedaquiline may offer the best profile for LAI formulation, Dr. Nuermberger said.

Early proof-of-concept in vivo studies have shown potential use of LAI bedaquiline for TB prevention in both drug-sensitive and drug-resistant TB contacts. Translational PK modeling and simulation predicted that a 1-g intramuscular injection of LAI bedaquiline could maintain therapeutic plasma concentrations in humans for greater than 1 month.

Dr. Nuermberger noted that novel diarylquinoline-based therapies, currently in phase 1 studies, may be even better candidates for LAI-based TB preventive therapy. Early data suggests these compounds may be 10-20 times more potent and have a lower CV risk profile than that of bedaquiline.
 

Considerations for development and implementation

“Despite the promising potential of long-acting injectables for TB, we are still in the very early stages,” said Dr. Nuermberger.

Ensuring and optimizing acceptance of LAI formulations, especially in at-risk populations, will be very important, he explained. Early involvement of children and pregnant women in studies of who may benefit most from LAI drugs will also be essential.

Other important considerations include cost-effectiveness, particularly in at-risk and vulnerable populations. Furthermore, new dedicated research and development programs are needed to continue to develop more drug candidates suitable for LAI.

“Long-acting formulations hold enormous promise to be transformative for combating TB, through simplification of delivery and overcoming issues of adherence that can compromise success of current interventions,” said Andrew Owen, PhD, of the University of Liverpool (England).

“The ability to deliver an entire course of drug in a single visit promises to ensure missed doses don’t compromise outcomes or place unnecessary selective pressure in favor of drug resistance,” Dr. Owen said.

“Recent studies showing the value of one-month oral treatment regimens for LTBI make long-acting formulations seem more realistic and drugs such as long-acting bedaquiline put a one-shot regimen within reach,” Charles W. Flexner, MD, of Johns Hopkins University, Baltimore, said in an interview.

While no LAIs have been approved for TB, Dr. Nuermberger was optimistic that the recent success of LAI formulations for HIV treatment and prevention will catalyze further efforts in the TB landscape.

Another coronavirus surge may be on the way in the United States as daily COVID-19 cases continue to plateau around 60,000, states begin to lift restrictions, and people embark on spring break trips this week, according to CNN.

Outbreaks will likely stem from the B.1.1.7 variant, which was first identified in the United Kingdom, and gain momentum during the next 6-14 weeks.

“Four weeks ago, the B.1.1.7 variant made up about 1%-4% of the virus that we were seeing in communities across the country. Today it’s up to 30%-40%,” Michael Osterholm, PhD, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, told NBC’s Meet the Press on March 7.

Dr. Osterholm compared the current situation with the “eye of the hurricane,” where the skies appear clear but more storms are on the way. Across Europe, 27 countries are seeing significant B.1.1.7 case increases, and 10 are getting hit hard, he said.

“What we’ve seen in Europe, when we hit that 50% mark, you see cases surge,” he said. “So right now, we do have to keep America as safe as we can from this virus by not letting up on any of the public health measures we’ve taken.”

In January, the CDC warned that B.1.1.7 variant cases would increase in 2021 and become the dominant variant in the country by this month. The United States has now reported more than 3,000 cases across 46 states, according to the latest CDC tally updated on March 7. More than 600 cases have been found in Florida, followed by more than 400 in Michigan.

The CDC has said the tally doesn’t represent the total number of B.1.1.7 cases in the United States, only the ones that have been identified by analyzing samples through genomic sequencing.

“Where it has hit in the U.K. and now elsewhere in Europe, it has been catastrophic,” Celine Gounder, MD, an infectious disease specialist with New York University Langone Health, told CNN on March 7.

The variant is more transmissible than the original novel coronavirus, and the cases in the United States are “increasing exponentially,” she said.

“It has driven up rates of hospitalizations and deaths and it’s very difficult to control,” Dr. Gounder said.

Vaccination numbers aren’t yet high enough to stop the predicted surge, she added. The United States has shipped more than 116 million vaccine doses, according to the latest CDC update on March 7. Nearly 59 million people have received at least one dose, and 30.6 million people have received two vaccine doses. About 9% of the U.S. population has been fully vaccinated.

States shouldn’t ease restrictions until the vaccination numbers are much higher and daily COVID-19 cases fall below 10,000 – and maybe “considerably less than that,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, told CNN on March 4.

Several states have already begun to lift COVID-19 safety protocols, with Texas and Mississippi removing mask mandates last week. Businesses in Texas will be able to reopen at full capacity on March 10. For now, public health officials are urging Americans to continue to wear masks, avoid crowds, and follow social distancing guidelines as vaccines roll out across the country.

“This is sort of like we’ve been running this really long marathon, and we’re 100 yards from the finish line and we sit down and we give up,” Dr. Gounder told CNN on Sunday. ‘We’re almost there, we just need to give ourselves a bit more time to get a larger proportion of the population covered with vaccines.”
