Nonmenstruating women were more likely to experience unexpected vaginal bleeding after receiving COVID-19 vaccinations, according to a new study.

The researchers suggested it could have been connected to the SARS-CoV-2 spike protein in the vaccines. The study was published in Science Advances.

After vaccinations became widely available, many women reported heavier menstrual bleeding than normal. Researchers at the Norwegian Institute of Public Health in Oslo examined the data, particularly among women who do not have periods, such as those who have been through menopause or are taking contraceptives.

The researchers used an ongoing population health survey called the Norwegian Mother, Father, and Child Cohort Study, Nature reported. They examined more than 21,000 responses from postmenopausal, perimenopausal, and nonmenstruating premenopausal women. Some were on long-term hormonal contraceptives.

They learned that 252 postmenopausal women, 1,008 perimenopausal women, and 924 premenopausal women reported having unexpected vaginal bleeding.

About half said the bleeding occurred within 4 weeks of the first or second shot or both. The risk of bleeding was up three to five times for premenopausal and perimenopausal women, and two to three times for postmenopausal women, the researchers found.

Postmenopausal bleeding is usually serious and can be a sign of cancer. “Knowing a patient’s vaccination status could put their bleeding incidence into context,” said Kate Clancy, a biological anthropologist at the University of Illinois at Urbana-Champaign.

The study received funding through the Norwegian Institute of Public Health and Research Council of Norway. The researchers reported no conflicts of interest.

TOPLINE:

Ultrasonography may serve as an alternative to radiography for diagnosing pediatric forearm fractures, thus reducing the number of children undergoing radiography at initial emergency department presentation, as well as their waiting time in ED.

METHODOLOGY:

• After the World Health Organization reported a lack of access to any diagnostic imaging in approximately two-thirds of the world population in 2010, ultrasonography has gained popularity in low- and middle-income countries.
• The initial use of ultrasonography is in accordance with the principle of maintaining radiation levels as low as reasonably achievable.
• The BUCKLED trial was conducted, including 270 pediatric patients (age, 5-15 years) who presented to the ED with isolated, acute, clinically nondeformed distal forearm fractures.
• The participants were randomly assigned to receive initial point-of-care ultrasonography (n = 135) or radiography (n = 135) in the ED.
• The primary outcome was the physical function of the affected arm at 4 weeks evaluated using the Pediatric Upper Extremity Short Patient-Reported Outcomes Measurement Information System (PROMIS) tool.

TAKEAWAY:

• At 4 weeks, mean PROMIS scores were 36.4 and 36.3 points in ultrasonography and radiography groups, respectively (mean difference, 0.1 point; 95% confidence interval, − 1.3 to 1.4), indicating noninferiority of ultrasonography over radiography.
• Ultrasonography and radiography groups showed similar efficacy in terms of PROMIS scores at 1 week (MD, 0.7 points; 95% CI, − 1.4 to 2.8) and 8 weeks (MD, 0.1 points; 95% CI, − 0.5 to 0.7).
• Participants in the ultrasonography group had a shorter length of stay in the ED (median difference, 15 minutes; 95% CI, 1-29) and a shorter treatment time (median difference, 28 minutes; 95% CI, 17-40) than those in the radiography group.
• No important fractures were missed with ultrasonography, and no significant difference was observed in the frequency of adverse events or unplanned returns to the ED between the two groups.

IN PRACTICE:

Noting the benefit-risk profile of an ultrasound-first approach in an ED setting, the lead author, Peter J. Snelling, MB, BS, MPH&TM, from Menzies Health Institute Queensland, Gold Coast, Australia, said: “It is highly unlikely that any important fractures would be missed using the protocol that we trained clinicians. The risk is low and the benefit is moderate, such as reducing length of stay and increased level of patient satisfaction.”

He further added that, “with an ultrasound-first approach, clinicians can scan the patient at time of review and may even be able to discharge them immediately (two-thirds of instances in our NEJM trial). This places the patient at the center of care being provided.”
 

SOURCE: 

Authors from the BUCKLED Trial Group published their study in the New England Journal of Medicine.

LIMITATIONS:

PROMIS scores may have been affected by variations in subsequent therapeutic interventions rather than the initial diagnostic method. PROMIS tool was not validated in children younger than 5 years of age.

DISCLOSURES:

The study was funded by the Emergency Medicine Foundation and others. The authors have declared no relevant interests to disclose.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study.

If you run into a health care provider these days and ask, “How are you doing?” you’re likely to get a response like this one: “You know, hanging in there.” You smile and move on. But it may be time to go a step further. If you ask that next question – “No, really, how are you doing?” Well, you might need to carve out some time.

It’s been a rough few years for those of us in the health care professions. Our lives, dominated by COVID-related concerns at home, were equally dominated by COVID concerns at work. On the job, there were fewer and fewer of us around as exploitation and COVID-related stressors led doctors, nurses, and others to leave the profession entirely or take early retirement. Even now, I’m not sure we’ve recovered. Staffing in the hospitals is still a huge problem, and the persistence of impersonal meetings via teleconference – which not only prevent any sort of human connection but, audaciously, run from one into another without a break – robs us of even the subtle joy of walking from one hallway to another for 5 minutes of reflection before sitting down to view the next hastily cobbled together PowerPoint.

I’m speaking in generalities, of course.

I’m talking about how bad things are now because, in truth, they’ve never been great. And that may be why health care workers – people with jobs focused on serving others – are nevertheless at substantially increased risk for suicide.

Analyses through the years have shown that physicians tend to have higher rates of death from suicide than the general population. There are reasons for this that may not entirely be because of work-related stress. Doctors’ suicide attempts are more often lethal – we know what is likely to work, after all.

But a focus on physicians fails to acknowledge the much larger population of people who work in health care, are less well-compensated, have less autonomy, and do not hold as respected a position in society. And, according to this paper in JAMA, it is those people who may be suffering most of all.

The study is a nationally representative sample based on the 2008 American Community Survey. Records were linked to the National Death Index through 2019.

Survey respondents were classified into five categories of health care worker, as you can see here. And 1,666,000 non–health care workers served as the control group.

People with long COVID have specific biomarkers in their blood, according to results of a study published in Nature. 

The findings may be a step toward creating blood tests to positively identify people with long COVID so specialized treatments can be employed, researchers said.

 “This is a decisive step forward in the development of valid and reliable blood testing protocols for long COVID,” said David Putrino, PhD., lead author and professor of rehabilitation and human performance and director of the Abilities Research Center at Icahn Mount Sinai Health System, New York.

Researchers from the Icahn School of Medicine at Mount Sinai and Yale School of Medicine looked at blood samples from about 270 people between January 2021 and June 2022. The people had never been infected with COVID, had fully recovered from an infection, or still showed symptoms at least four months after infection.

Using machine learning, the research teams were able to differentiate between people with and without long COVID with 96% accuracy based on distinctive features in the blood samples, according to a news release from Mount Sinai.

People with long COVID had abnormal T-cell activity and low levels of the hormone cortisol. Cortisol helps people feel alert and awake, which would explain why people with long COVID often report fatigue, NBC News said in a report on the study.

“It was one of the findings that most definitively separated the folks with long Covid from the people without long Covid,” Dr. Putrino told NBC News.

The study also found that long COVID appears to reactivate latent viruses including Epstein-Barr and mononucleosis, the study said.

The blood tests could allow doctors to come up with specialized treatments in people who report a wide variety of long COVID symptoms, Dr. Putrino said. 

“There is no ‘silver bullet’ for treating long COVID, because it is an illness that infiltrates complex systems such as the immune and hormonal regulation,” he said.

The Centers for Disease Control and Prevention says about one in five Americans who had COVID still have long COVID. Symptoms include fatigue, brain fog, dizziness, digestive problems, and loss of smell and taste.

The antiviral COVID medication made by Merck can cause mutations in the coronavirus that occasionally spread to other people, according to a study published in the online journal Nature.

There’s no evidence that molnupiravir, sold under the brand name Lagevrio, has caused the creation of more transmissible or severe variants of COVID, the study says, but researchers called for more scrutiny of the drug.

Researchers looked at 15 million COVID genomes and discovered that hallmark mutations linked to molnupiravir increased in 2022, especially in places where the drug was widely used, such as the United States and the United Kingdom. Levels of the mutations were also found in populations where the drug was heavily prescribed, such as seniors.

Molnupiravir is an antiviral given to people after they show signs of having COVID-19. It interferes with the COVID-19 virus’s ability to make copies of itself, thus stopping the spread of the virus throughout the body and keeping the virus level low.

The study found the virus can sometimes survive molnupiravir, resulting in mutations that have spread to other people.

Theo Sanderson, PhD, the lead author on the study and a postdoctoral researcher at the Francis Crick Institute in London, told The Guardian that the implications of the mutations were unclear.

“The signature is very clear, but there aren’t any widely circulating variants that have the signature. At the moment there’s nothing that’s transmitted very widely that’s due to molnupiravir,” he said.

The study doesn’t say people should not use molnupiravir but calls for public health officials to scrutinize it.

“The observation that molnupiravir treatment has left a visible trace in global sequencing databases, including onwards transmission of molnupiravir-derived sequences, will be an important consideration for assessing the effects and evolutionary safety of this drug,” the researchers concluded.

When reached for comment, Merck questioned the evidence.

“The authors assume these mutations were associated with viral spread from molnupiravir-treated patients without documented evidence of that transmission. Instead, the authors rely on circumstantial associations between the region from which the sequence was identified and time frame of sequence collection in countries where molnupiravir is available to draw their conclusions,” the company said.

The Food and Drug Administration authorized the use of molnupiravir for the treatment of mild to moderate COVID-19 in adults in December 2021. The FDA has also authorized the use of nirmatrelvir/ritonavir (Paxlovid), an antiviral made by Pfizer.

Molnupiravir is an antiviral given to people after they show signs of having COVID-19. It interferes with the COVID-19 virus’s ability to make copies of itself, thus stopping the spread of the virus throughout the body and keeping the virus level low.

The study found the virus can sometimes survive molnupiravir, resulting in mutations that have spread to other people.

Theo Sanderson, PhD, the lead author on the study and a postdoctoral researcher at the Francis Crick Institute in London, told The Guardian that the implications of the mutations were unclear.

“The signature is very clear, but there aren’t any widely circulating variants that have the signature. At the moment there’s nothing that’s transmitted very widely that’s due to molnupiravir,” he said.

The study doesn’t say people should not use molnupiravir but calls for public health officials to scrutinize it.

“The observation that molnupiravir treatment has left a visible trace in global sequencing databases, including onwards transmission of molnupiravir-derived sequences, will be an important consideration for assessing the effects and evolutionary safety of this drug,” the researchers concluded.

When reached for comment, Merck questioned the evidence.

“The authors assume these mutations were associated with viral spread from molnupiravir-treated patients without documented evidence of that transmission. Instead, the authors rely on circumstantial associations between the region from which the sequence was identified and time frame of sequence collection in countries where molnupiravir is available to draw their conclusions,” the company said.

The Food and Drug Administration authorized the use of molnupiravir for the treatment of mild to moderate COVID-19 in adults in December 2021. The FDA has also authorized the use of nirmatrelvir/ritonavir (Paxlovid), an antiviral made by Pfizer.

It was just a routine checkup – or so she thought. But this time, Marnina Miller’s love interest came along. The pair headed to an STD clinic in Houston, where Ms. Miller worked, to get tested for syphilis and HIV. With an already compromised immune system because of an HIV diagnosis 9 years ago, it is critical for Ms. Miller to ensure she is clear of any other diseases. She tested negative for syphilis. Her partner, on the other hand, tested positive for latent (or stage 3) syphilis. 

Syphilis has been on the rise in the United States for more than 2 decades. From 2017 to 2021, the number of cases shot up 75% (to 176,713), according to the Centers for Disease Control and Prevention. Houston – the fourth-largest city in the United States – seems to be at the epicenter. Between 2019 and 2022, there was a 128% rise in syphilis cases there, particularly among women and people of color, according to the Houston Health Department. This summer, drugmaker Pfizer reported a widespread shortage of the antibiotic penicillin, which is used to cure early-stage syphilis and treat latent syphilis. 

“I was immediately scared,” Ms. Miller said. “I was nervous about what that meant for me because we did kiss before. And, although I am openly living with HIV, there is little education around syphilis and how it is contracted.”

The Houston Health Department has been warning Houstonites to take this public health crisis seriously by practicing safe sex and getting tested if they’re sexually active. There has also been a ninefold increase in congenital syphilis in Houston and Harris County, Tex. To help curb the spread, residents can now get free testing for sexually transmitted diseases at Houston health clinics. 

“It is crucial for pregnant women to seek prenatal care and syphilis testing to protect themselves from an infection that could result in the deaths of their babies,” said Marlene McNeese Ward, deputy assistant director of the Houston Health Department’s Bureau of HIV/STI and Viral Hepatitis Prevention. She said a pregnant woman needs to get tested for syphilis three times during her pregnancy.

There are four stages of syphilis: primary, secondary, latent, and tertiary. Oral, anal, and vaginal sex are some of the ways the disease can spread. Some people who contract syphilis never have symptoms and could have the disease for years without knowing.

Penicillin can cure both syphilis and congenital syphilis. The antibiotic cannot reverse damage done to organs via infection, especially if the disease has greatly progressed before treatment. 

Sergino Nicolas, MD, creates TikTok videos and Instagram reels to raise awareness about the outbreak. The Pittsburgh-based emergency medical doctor said there is often a “nonchalant” attitude toward STDs among some people in their 20s and 30s. Being unaware of the consequences of syphilis could drive that attitude. “With thoughts like ‘I can just get treated,’ I think there is danger in that, because when you have these infections, [irreversible] complications can occur,” he said.

Preconceived notions among this age group that oral sex is a safer alternative to vaginal or anal sex is also common, Dr. Nicolas said. “Any time you might have infected secretions or be exposed to mucosa, including the vaginal mucosa, that can result in spreading the infection.”

Women of color have been particularly impacted by the outbreak. Syphilis has a wide range of signs and symptoms, and that could play a major role, Dr. Nicolas said. Lack of education on the dangers of unprotected sex, particularly with multiple sexual partners, could be another reason, as this increases rates of yeast infections and STDs, he said.

Another potential factor: Sexually explicit music and entertainment can also cloud judgment on whether to engage in sexual activity, Dr. Nicolas said. Younger generations can especially fall prey to this. “There have been new artists over the past few months that have really been pushing for ‘female empowerment’ in a sense,” he said. “At the same time, they can also push a narrative more so pertaining to promiscuity, which could result in certain psychological effects” that could lead to unsafe sex practices.

Public health activists in Houston are spreading the word on the importance of getting tested for STDs. Kevin Anderson is the founder of the T.R.U.T.H. Project, a Houston-based nonprofit that educates and mobilizes LGBTQ communities of color through social arts that promote sexual, mental, and physical health.

While celebrating its 10th anniversary, T.R.U.T.H. Project is creatively promoting syphilis education and awareness. The organization’s recent events have included an open-mic night called “Heart and Soul,” with free STD testing on site for attendees. It also hosted a sex-positive night aiming to educate attendees about STDs and safe sex practices. Self-love, self-care, and self-awareness of one’s body is one of the group’s most prominent messages. “If something feels or looks different, love yourself enough to be proactive in following up to find out what’s going on – because avoidance leads to outbreaks,” Mr. Anderson said.

A real-world study published in  JAMA Open Network found that Pfizer’s COVID-19 antiviral Paxlovid is now less effective at preventing hospitalization or death in high-risk patients, compared with earlier studies. But when looking at death alone, the antiviral was still highly effective. 

Paxlovid was about 37% effective at preventing death or hospitalization in high-risk patients, compared with no treatment. The study also looked at the antiviral Lagevrio, made by Merck, and found it was about 41% effective. In preventing death alone, Paxlovid was about 84% effective, compared with no treatment, and Lagevrio was about 77% effective.

The investigators, of the University of North Carolina at Chapel Hill and the Cleveland Clinic, examined electronic health records of 68,867 patients at hospitals in Cleveland and Florida who were diagnosed with COVID from April 1, 2022, to Feb. 20, 2023.

For Paxlovid, the effectiveness against death and hospitalization was lower than the effectiveness rate of about 86% found in clinical trials in 2021, according to Bloomberg. 

The difference in effectiveness in the real-world and clinical studies may have occurred because the early studies were conducted with unvaccinated people. Also, the virus has evolved since those first studies, Bloomberg reported. 

The researchers said Paxlovid and Lagevrio are recommended for use because they reduce hospitalization and death among high-risk patients who get COVID, even taking recent Omicron subvariants into account.

“These findings suggest that the use of either nirmatrelvir (Paxlovid) or molnupiravir (Lagevrio) is associated with reductions in mortality and hospitalization in patients infected with Omicron, regardless of age, race and ethnicity, virus strain, vaccination status, previous infection status, or coexisting conditions,” the researchers wrote. “Both drugs can, therefore, be used to treat nonhospitalized patients who are at high risk of progressing to severe COVID-19.”

Both drugs should be taken within 5 days of the onset of COVID symptoms.

The study was supported by the National Institutes of Health. Three coauthors reported conflicts of interest with various companies and organizations.

Taking creatine as a supplement for 6 months appears to significantly improve clinical features of post–COVID-19 fatigue syndrome (PVFS or long COVID), a small randomized, placebo-controlled, double-blinded study suggests.

Researchers, led by Jelena Slankamenac, with Applied Bioenergetics Lab, Faculty of Sport and PE, University of Novi Sad, Serbia, published their findings in Food, Science & Nutrition .

“This is the first human study known to the authors that evaluated the efficacy and safety of supplemental creatine for fatigue, tissue bioenergetics, and patient-reported outcomes in patients with post–COVID-19 fatigue syndrome,” the authors write.

They say the findings may be attributed to creatine’s “energy-replenishing and neuroprotective activity.”
 

Significant reductions in symptoms

Researchers randomized the 12 participants into two groups of 6 each. The creatine group received 4 g creatine monohydrate per day, while the placebo group received the same amount of inulin.

At 3 months, dietary creatine supplements produced a significant reduction in fatigue, compared with baseline values ( P = .04) and significantly improved scores for several long COVID–related symptoms, including loss of taste, breathing difficulties, body aches, headache, and difficulties concentrating) ( P < .05), the researchers report.

Intervention effect sizes were assessed by Cohen statistics, with a d of at least 0.8 indicating a large effect.

Among highlights of the results were that patients reported a significant 77.8% drop in scores for concentration difficulties at the 3-month follow-up (Cohen’s effect, d = 1.19) and no concentration difficulties at the 6-month follow-up (Cohen’s effect, d = 2.46).

Total creatine levels increased in several locations across the brain (as much as 33% for right parietal white matter). No changes in tissue creatine levels were found in the placebo group during the trial.

“Since PVFS is characterized by impaired tissue bioenergetics ..., supplemental creatine might be an effective dietary intervention to uphold brain creatine in post–COVID-19 fatigue syndrome,” the authors write.

The authors add that creatine supplements for long COVID patients could benefit organs beyond the brain as participants saw “a significant drop in lung and body pain after the intervention.”
 

Unanswered questions

Some experts said the results should be interpreted with caution.

“This research paper is very interesting,” says Nisha Viswanathan, MD, director of the long COVID program at University of California, Los Angeles, “but the limited number of patients makes the results difficult to generalize.”

Dr. Viswanathan, who was not part of the study, pointed out that the patients included in this study had a recent COVID infection (under 3 months).

“Acute COVID infection can take up to 3 months to resolve,” she says. “We define patients with long COVID as those with symptoms lasting greater than 3 months. Therefore, these patients could have had improvements in their fatigue due to the natural course of the illness rather than creatine supplementation.”

Alba Azola, MD, assistant professor in the department of physical medicine and rehabilitation at Johns Hopkins University, Baltimore, said she also was troubled by the window of 3 months for recent COVID infection.

She said she would like to see results for patients who have ongoing symptoms for at least 6 months after infection, especially given creatine supplements’ history in research.

Creatine supplements for other conditions, such as fibromyalgia and chronic fatigue syndrome, have been tested for nearly 2 decades, she pointed out, with conflicting findings, something the authors acknowledge in the paper.

“I think it’s premature to say (creatine) is the key,” she says. She added that the small sample size is important to consider given the heterogeneity of patients with long COVID.

That said, Dr. Azola says, she applauds all efforts to find treatments for long COVID, especially randomized, controlled studies like this one.
 

No major side effects

No major side effects were reported for either intervention, except for transient mild nausea reported by one patient after taking creatine.

Compliance with the intervention was 90.6% ± 3.5% in the creatine group and 95.3% ± 5.0% in the control group (P = .04).

Participants were eligible for inclusion if they were 18-65 years old, had a positive COVID test within the last 3 months (documented by a valid polymerase chain reaction [PCR] or antigen test performed in a COVID-19–certified lab); had moderate to severe fatigue; and at least one additional COVID-related symptom, including loss of taste or smell, breathing trouble, lung pain, body aches, headaches, or difficulties concentrating.

The authors acknowledge that they selected a sample of young to middle-aged adults experiencing moderate long COVID symptoms, and it’s unknown whether creatine is equally effective in other PVFS populations, such as elderly people, children, or patients with less or more severe disease.

At 3 months, dietary creatine supplements produced a significant reduction in fatigue, compared with baseline values ( P = .04) and significantly improved scores for several long COVID–related symptoms, including loss of taste, breathing difficulties, body aches, headache, and difficulties concentrating) ( P < .05), the researchers report.

Intervention effect sizes were assessed by Cohen statistics, with a d of at least 0.8 indicating a large effect.

Among highlights of the results were that patients reported a significant 77.8% drop in scores for concentration difficulties at the 3-month follow-up (Cohen’s effect, d = 1.19) and no concentration difficulties at the 6-month follow-up (Cohen’s effect, d = 2.46).

Total creatine levels increased in several locations across the brain (as much as 33% for right parietal white matter). No changes in tissue creatine levels were found in the placebo group during the trial.

“Since PVFS is characterized by impaired tissue bioenergetics ..., supplemental creatine might be an effective dietary intervention to uphold brain creatine in post–COVID-19 fatigue syndrome,” the authors write.

The authors add that creatine supplements for long COVID patients could benefit organs beyond the brain as participants saw “a significant drop in lung and body pain after the intervention.”
 

Unanswered questions

Some experts said the results should be interpreted with caution.

“This research paper is very interesting,” says Nisha Viswanathan, MD, director of the long COVID program at University of California, Los Angeles, “but the limited number of patients makes the results difficult to generalize.”

Dr. Viswanathan, who was not part of the study, pointed out that the patients included in this study had a recent COVID infection (under 3 months).

“Acute COVID infection can take up to 3 months to resolve,” she says. “We define patients with long COVID as those with symptoms lasting greater than 3 months. Therefore, these patients could have had improvements in their fatigue due to the natural course of the illness rather than creatine supplementation.”

Alba Azola, MD, assistant professor in the department of physical medicine and rehabilitation at Johns Hopkins University, Baltimore, said she also was troubled by the window of 3 months for recent COVID infection.

She said she would like to see results for patients who have ongoing symptoms for at least 6 months after infection, especially given creatine supplements’ history in research.

Creatine supplements for other conditions, such as fibromyalgia and chronic fatigue syndrome, have been tested for nearly 2 decades, she pointed out, with conflicting findings, something the authors acknowledge in the paper.

“I think it’s premature to say (creatine) is the key,” she says. She added that the small sample size is important to consider given the heterogeneity of patients with long COVID.

That said, Dr. Azola says, she applauds all efforts to find treatments for long COVID, especially randomized, controlled studies like this one.
 

No major side effects

No major side effects were reported for either intervention, except for transient mild nausea reported by one patient after taking creatine.

Compliance with the intervention was 90.6% ± 3.5% in the creatine group and 95.3% ± 5.0% in the control group (P = .04).

Participants were eligible for inclusion if they were 18-65 years old, had a positive COVID test within the last 3 months (documented by a valid polymerase chain reaction [PCR] or antigen test performed in a COVID-19–certified lab); had moderate to severe fatigue; and at least one additional COVID-related symptom, including loss of taste or smell, breathing trouble, lung pain, body aches, headaches, or difficulties concentrating.

The authors acknowledge that they selected a sample of young to middle-aged adults experiencing moderate long COVID symptoms, and it’s unknown whether creatine is equally effective in other PVFS populations, such as elderly people, children, or patients with less or more severe disease.

The American College of Physicians has issued an updated version of its living, rapid practice point guideline on the best treatment options for outpatients with confirmed COVID-19 in the era of the dominant Omicron variant of SARS-CoV-2. The recommendations in version 2 apply to persons presenting with mild to moderate infection and symptom onset in the past 5 days who are at high risk for progression to severe disease and potential hospitalization or death.

Version 1 appeared in late 2022.

While outpatient management is appropriate for most patients, treatment should be personalized and based on careful risk stratification and informed decision-making, said the guideline authors, led by Amir Qaseem, MD, PhD, MHA, vice president of clinical policy and the Center for Evidence Reviews at the ACP in Philadelphia.
 

Practice points

• Consider the oral antivirals nirmatrelvir-ritonavir (Paxlovid) or molnupiravir (Lagevrio) for symptomatic outpatients with confirmed mild to moderate COVID-19 who are within 5 days of the onset of symptoms and at high risk for progressing to severe disease.

New evidence for the Omicron variant suggests a possible net benefit of the antiviral molnupiravir versus standard or no treatment in terms of reducing recovery time if treatment is initiated within 5 days of symptom onset. Nirmatrelvir-ritonavir was associated with reductions in COVID-19 hospitalization and all-cause mortality.

“The practice points only address [whether] treatments work compared to placebo, no treatment, or usual care,” cautioned Linda L. Humphrey, MD, MPH, MACP, chair of the ACP’s Population Health and Medical Science Committee and a professor of medicine at Oregon Health and Science University VA Portland Health Care System. The ACP continues to monitor the evidence. “Once enough evidence has emerged, it will be possible to compare treatments to each other. Until that time we are unable to determine if there is an advantage to using one treatment over another.”

• Do not use the antiparasitic ivermectin (Stromectol) or the monoclonal antibody sotrovimab (Xevudy) to treat this patient population. “It is not expected to be effective against the Omicron variant,” Dr. Humphrey said.

There was no evidence to support the use of medications such as corticosteroids, antibiotics, antihistamines, SSRIs, and multiple other agents.

“The guideline is not a departure from previous knowledge and reflects what appears in other guidelines and is already being done generally in practice,” said Mirella Salvatore, MD, an associate professor of medicine and population health sciences at Weill Cornell Medicine, New York, who was not involved in the ACP statement. It is therefore unlikely the recommendations will trigger controversy or negative feedback, added Dr. Salvatore, who is also a spokesperson for the Infectious Diseases Society of America. “We believe that our evidence-based approach, which considers the balance of benefits and harms of various treatments, will be embraced by the physician community,” Dr. Humphrey said.

The updated recommendations are based on new data from the evidence review of multiple treatments, which concluded that both nirmatrelvir-ritonavir and molnupiravir likely improve outcomes for outpatients with mild to moderate COVID-19. The review was conducted after the emergence of the Omicron variant by the ACP Center for Evidence Reviews at Cochrane Austria/University for Continuing Education Krems (Austria).


 

Review details

Inclusion criteria were modified to focus on the Omicron variant by limiting eligible studies to only those enrolling patients on or after Nov. 26, 2021. The investigators included two randomized controlled trials and six retrospective cohort studies and ranked quality of evidence for the effectiveness of the following treatments, compared with usual care or no treatment: azithromycin, camostat mesylate, chloroquine-hydroxychloroquine, chlorpheniramine, colchicine, convalescent plasma, corticosteroids, ensitrelvir, favipiravir, fluvoxamine, ivermectin, lopinavir-ritonavir, molnupiravir, neutralizing monoclonal antibodies, metformin, niclosamide, nitazoxanide, nirmatrelvir-ritonavir, and remdesivir.

It compared results for all-cause and COVID-specific mortality, recovery, time to recovery, COVID hospitalization, and adverse and serious adverse events.

Nirmatrelvir-ritonavir was associated with a reduction in hospitalization caused by COVID-19 of 0.7% versus 1.2% (moderate certainty of evidence [COE]) and a reduction in all-cause mortality of less than 0.1% versus 0.2% (moderate COE).

Molnupiravir led to a higher recovery rate of 31.8% versus 22.6% (moderate COE) and a reduced time to recovery of 9 versus 15 median days (moderate COE). It had no effect, however, on all-cause mortality: 0.02% versus 0.04% (moderate COE). Nor did it affect the incidence of serious adverse events: 0.4% versus 0.3% (moderate COE).

“There have been no head-to-head comparative studies of these two treatments, but nirmatrelvir-ritonavir appears to be the preferred treatment,” Dr. Salvatore said. She noted that molnupiravir cannot be used in pregnant women or young persons under age 18, while nirmatrelvir-ritonavir carries the risk of drug interactions. Viral rebound and recurrence of symptoms have been reported in some patients receiving nirmatrelvir-ritonavir.

In other review findings, ivermectin had no effect on time to recovery (moderate COE) and adverse events versus placebo (low COE). Sotrovimab resulted in no difference in all-cause mortality, compared with no treatment (low COE). There were no eligible studies for all of the other treatments of interest nor were there any that specifically evaluated the benefits and harms of treatments for the Omicron variant.

The panel pointed to the need for more evaluation of the efficacy, effectiveness, and comparative effectiveness, as well as harms of pharmacologic and biologic treatments of COVID-19 in the outpatient setting, particularly in the context of changing dominant SARS-CoV-2 variants and subvariants.

Another area requiring further research is the effectiveness of retreatment in patients with previous COVID-19 infection. Subgroup analyses are also needed to assess whether the efficacy and effectiveness of outpatient treatments vary by age, sex, socioeconomic status, and comorbid conditions – or by SARS-CoV-2 variant, immunity status (prior SARS-CoV-2 infection, vaccination status, or time since infection or vaccination), symptom duration, or disease severity.

Dr. Salvatore agreed that more research is needed in special convalescent groups. “For instance, those with cancer who are immunocompromised may need longer treatment and adjunctive treatment with convalescent plasma. But is difficult to find a large enough study with 5,000 immunocompromised patients.”

Financial support for the development of the practice points came exclusively from the ACP operating budget. The evidence review was funded by the ACP. The authors disclosed no relevant high-level competing interests with regard to this guidance, although several authors reported intellectual interests in various areas of research. Dr. Salvatore disclosed no conflicts of interest relevant to her comments but is engaged in influenza research for Genentech.

The frequency of medication errors among children who take drugs to treat attention-deficit/hyperactivity disorder reported to U.S. poison control centers increased by nearly 300% over a 22-year period, according to results of a study published in the journal Pediatrics.

The dramatic jump is likely attributable to an increase in the prescribing of ADHD medications for children. According to the study authors, in 2019, nearly 10% of children in the United States had been diagnosed with ADHD, and some 3.3 million – or about 5% of all children in the country – had received a prescription for an ADHD medication.

“Because therapeutic errors are preventable, more attention should be given to patient and caregiver education and development of improved child-resistant medication dispensing and tracking systems,” the authors commented.

The investigators analyzed data from the National Poison Data System from 2000 through 2021 for therapeutic errors associated with ADHD medication among patients younger than 20 years.

“As medicine changes, it’s nice to look back at some of these things and see how some of these problems have changed,” said Natalie I. Rine, PharmD, a coauthor of the study and director of the Central Ohio Poison Center at Nationwide Children’s Hospital in Columbus.

The researchers identified 124,383 such errors reported to U.S. poison centers during the study period. The frequency increased by 299%.

Two-thirds (66.6%) of the exposures involved children aged 6-12 years, three-fourths (76.4%) were among males, and half (50.5%) involved amphetamines and related compounds. Most (79.7%) therapeutic errors were linked to exposure to a single substance. Nearly 83% of patients did not receive treatment at a health care facility; however, 2.3% were admitted to the hospital, and 4.2% had a “serious medical outcome,” the researchers found.

The most common scenarios were “inadvertently took or given medication twice” (53.9%), followed by “inadvertently took or given someone else’s medication” (13.4%) and “wrong medication taken or given” (12.9%), according to the researchers. Two percent involved mistakes by a pharmacist or nurse.
 

Easily preventable

Dr. Rine attributed the errors to simple mistakes and said they were likely the product of busy households and distracted caregivers. She added that the errors are easily avoided by storing the medication properly, keeping a sheet with the medication to document what was taken and when, and using a pillbox or one of many apps that can assist in documenting the dispensing of medications.

“I think the biggest thing is that a lot of these errors are preventable, more than anything else,” Dr. Rine said.

The increase in ADHD diagnoses among children and the subsequent prescribing of medications are reasons for the nearly 300% increase in poison control calls. A 2018 study showed that the estimated prevalence of ADHD diagnoses among U.S. children and adolescents increased from 6.1% in 1997-1998 to 10.2% in 2015-2016. The Centers for Disease Control and Prevention states that 6 million children and adolescents aged 3-17 years have been diagnosed with ADHD, and 62% have received ADHD medication.

Colleen Kraft, MD, a pediatrician at Children’s Hospital Los Angeles, said she was not surprised by the reported increase in errors. In addition to the simple uptick in ADHD diagnoses and prescriptions in the past 2 decades, Dr. Kraft said the growing variety of ADHD medication is a cause for more errors.

“Because we have so many more different types of these medications, it’s easy to confuse them, and it’s easy to make an error when you give this to a child,” she said in an interview.

Dr. Kraft also hypothesized that because ADHD can have a genetic component, some parents with undiagnosed and untreated ADHD are responsible for their child’s medication, a scenario ripe for mistakes.
 

Potential dangers

Not all ADHD medicinal overdosing is created equal, Dr. Kraft pointed out. Doubling up on a stimulant such as methylphenidate (Ritalin) or the combination of amphetamine and dextroamphetamine (Adderall) may cause headaches, suppress appetite, and cause an upset stomach, although those symptoms usually clear up in a few hours.

However, she noted, the use of alpha-1 adrenergic blockers is more concerning. Also used to treat high blood pressure, medications such as guanfacine and clonidine cause sedation. A double dose can cause blood pressure to decrease to dangerous levels.

The study’s primary limitation was bias in self-reporting, which may have led to underreporting of incidences, according to the researchers. Not every case in which an error occurs that involves a child’s taking ADHD medication gets reported to poison control, because some will take a wait-and-see approach and may not call if their child is asymptomatic.

“Our data is only as good as what the callers report to us,” Dr. Rine said.

The frequency of medication errors among children who take drugs to treat attention-deficit/hyperactivity disorder reported to U.S. poison control centers increased by nearly 300% over a 22-year period, according to results of a study published in the journal Pediatrics.

The dramatic jump is likely attributable to an increase in the prescribing of ADHD medications for children. According to the study authors, in 2019, nearly 10% of children in the United States had been diagnosed with ADHD, and some 3.3 million – or about 5% of all children in the country – had received a prescription for an ADHD medication.

“Because therapeutic errors are preventable, more attention should be given to patient and caregiver education and development of improved child-resistant medication dispensing and tracking systems,” the authors commented.

The investigators analyzed data from the National Poison Data System from 2000 through 2021 for therapeutic errors associated with ADHD medication among patients younger than 20 years.

“As medicine changes, it’s nice to look back at some of these things and see how some of these problems have changed,” said Natalie I. Rine, PharmD, a coauthor of the study and director of the Central Ohio Poison Center at Nationwide Children’s Hospital in Columbus.

The researchers identified 124,383 such errors reported to U.S. poison centers during the study period. The frequency increased by 299%.

Two-thirds (66.6%) of the exposures involved children aged 6-12 years, three-fourths (76.4%) were among males, and half (50.5%) involved amphetamines and related compounds. Most (79.7%) therapeutic errors were linked to exposure to a single substance. Nearly 83% of patients did not receive treatment at a health care facility; however, 2.3% were admitted to the hospital, and 4.2% had a “serious medical outcome,” the researchers found.

The most common scenarios were “inadvertently took or given medication twice” (53.9%), followed by “inadvertently took or given someone else’s medication” (13.4%) and “wrong medication taken or given” (12.9%), according to the researchers. Two percent involved mistakes by a pharmacist or nurse.
 

Easily preventable

Dr. Rine attributed the errors to simple mistakes and said they were likely the product of busy households and distracted caregivers. She added that the errors are easily avoided by storing the medication properly, keeping a sheet with the medication to document what was taken and when, and using a pillbox or one of many apps that can assist in documenting the dispensing of medications.

“I think the biggest thing is that a lot of these errors are preventable, more than anything else,” Dr. Rine said.

The increase in ADHD diagnoses among children and the subsequent prescribing of medications are reasons for the nearly 300% increase in poison control calls. A 2018 study showed that the estimated prevalence of ADHD diagnoses among U.S. children and adolescents increased from 6.1% in 1997-1998 to 10.2% in 2015-2016. The Centers for Disease Control and Prevention states that 6 million children and adolescents aged 3-17 years have been diagnosed with ADHD, and 62% have received ADHD medication.

Colleen Kraft, MD, a pediatrician at Children’s Hospital Los Angeles, said she was not surprised by the reported increase in errors. In addition to the simple uptick in ADHD diagnoses and prescriptions in the past 2 decades, Dr. Kraft said the growing variety of ADHD medication is a cause for more errors.

“Because we have so many more different types of these medications, it’s easy to confuse them, and it’s easy to make an error when you give this to a child,” she said in an interview.

Dr. Kraft also hypothesized that because ADHD can have a genetic component, some parents with undiagnosed and untreated ADHD are responsible for their child’s medication, a scenario ripe for mistakes.
 

Potential dangers

Not all ADHD medicinal overdosing is created equal, Dr. Kraft pointed out. Doubling up on a stimulant such as methylphenidate (Ritalin) or the combination of amphetamine and dextroamphetamine (Adderall) may cause headaches, suppress appetite, and cause an upset stomach, although those symptoms usually clear up in a few hours.

However, she noted, the use of alpha-1 adrenergic blockers is more concerning. Also used to treat high blood pressure, medications such as guanfacine and clonidine cause sedation. A double dose can cause blood pressure to decrease to dangerous levels.

The study’s primary limitation was bias in self-reporting, which may have led to underreporting of incidences, according to the researchers. Not every case in which an error occurs that involves a child’s taking ADHD medication gets reported to poison control, because some will take a wait-and-see approach and may not call if their child is asymptomatic.

“Our data is only as good as what the callers report to us,” Dr. Rine said.
