A well-known, inexpensive diabetes drug appears to cut the risk of developing long COVID, hopeful-but-early new research suggests.
The study, published Thursday in the peer-reviewed journal Lancet Infectious Diseases, found outpatient treatment with the drug metformin — a common treatment for Type 2 diabetes — reduced long COVID incidence among infected patients by 41 per cent.
Roughly six per cent of those taking metformin went on to develop the condition, compared to close to 11 per cent of those in the placebo group. Participants on metformin were also less likely to be hospitalized roughly a month after infection by SARS-CoV-2, the virus that causes COVID-19.
“Metformin has clinical benefits when used as outpatient treatment for COVID-19 and is globally available, low-cost and safe,” wrote the research team.
Lead author Dr. Carolyn Bramante, a physician-scientist with the University of Minnesota in Minneapolis, told CBC News that the effect was even larger when metformin was given quickly �— in less than four days — during someone’s infection. She said metformin may be helping patients fight off the virus, or reducing inflammation, though more research is needed to figure out why the drug appears to work.
“Our data don’t suggest anything about whether metformin would treat long COVID in someone who already has it,” she said, “so that’s an important area of research where trials should be done.”
Two other drugs, ivermectin and fluvoxamine, were also studied, but neither made a difference on the incidence of long COVID.
‘Potentially landmark’ findings
The research involved randomized, quadruple-blind trials on roughly 1,400 people at six sites in the U.S., through multiple waves of the pandemic, and looked at both vaccinated and unvaccinated individuals — though only those with first-time infections.
Outside medical experts say it’s one of the more robust studies yet on a potential preventative aimed at long COVID.
“I think it’s a significant start to having a better understanding of the role of metformin in reducing the risk of long COVID,” said Dr. Isaac Bogoch, an infectious diseases specialist with the University Health Network in Toronto. “There’s been hints of data over the last couple of years … this furthers that discussion.”
If confirmed, the findings are “profound and potentially landmark on two distinct counts,” wrote Dr. Jeremy Faust, from Harvard Medical School, in an accompanying commentary in the Lancet.
The paper offers the “first high-quality evidence” showing incidence of long COVID can be reduced through a medical intervention, he wrote, and offers an important medical contribution regarding the very existence of the condition, since “a treatment can only be effective if there is something to treat.”
In a statement, Dr. Frances Williams, professor of genetic epidemiology at King’s College London, cautioned there would need to be extensive use of metformin to realize the study’s seemingly impressive outcomes.
“In total, 564 people were exposed to the drug metformin to prevent 23 hypothetical cases. This means 24 people would need to take metformin to prevent one case of [long COVID].”
Fatigue, ‘brain fog’
Marked by a variety of lingering symptoms such as fatigue, shortness of breath and feelings of ‘brain fog’, and formally known as post COVID-19 condition, long COVID is thought to be less common by this point in the pandemic, largely thanks to widespread protection from vaccinations.
But the condition can still be debilitating for some, including millions of people around the world — including many in Canada — who became infected with earlier SARS-CoV-2 variants before the arrival of vaccines.
While physicians are hopeful the new research may fuel additional study and potentially help bring down long COVID rates even further, there were some key limitations.
For one thing, it only focused on adults between age 30 and 85 who were overweight or had obesity — so the drug’s impact on individuals of other body weights isn’t yet known.
“It’s not entirely clear how generalizable this will be,” Bogoch said.
In his comment for the Lancet, Faust also noted that since the participants were given a diabetes drug, there may be reduced symptoms linked to undiagnosed diabetes among the patients. “Furthermore, the mechanism of action by which metformin might reduce the incidence of long COVID remains unclear,” he wrote.
Dr. Lynora Saxinger, a professor in the division of infectious diseases at the University of Alberta, noted the study didn’t follow long COVID patients using any “standardized criteria.”
But, she said in an email to CBC News, “it still is really positive and encouraging that a treatment in early COVID could reduce risk of prolonged symptoms: additional studies in other patient groups and with more specific long COVID symptom followup will be really helpful.”
Bogoch stressed that, while the drug shows potential, it wouldn’t “solve all of our issues with long COVID.” However, it could become an important tool given its decades-old safety profile, he said.
“If this is something that, indeed, pans out, and if metformin truly has some properties that reduce the risk of developing long COVID, that’s wonderful because it’s a cheap, widely available [drug].”
The Key Role of Trustworthy Babysitters in Balancing Work and Family Life
Are you a busy parent in constant pursuit of the elusive work-life balance? We know firsthand how overwhelming and challenging it can be to juggle professional commitments while still having quality time with your children.
That’s why we’re here to discuss an essential ingredient that unlocks the secret to harmony: trustworthy babysitters.
What Characteristics Parents Should Look for When Choosing a Babysitter?
Parents should look for a few key characteristics when choosing a babysitter. A good babysitter should be patient, responsible, and reliable. They should also be comfortable with children and have prior experience caring for them.
Besides, the babysitter must be able to communicate effectively and follow directions well. The babysitter should be someone the parents can trust to care for their children in their absence.
Strategies for Parents to Establish Reasonable Anticipations
As a parent, finding babysitters you can trust to care for your children is vital. However, it is also important to establish reasonable expectations for your babysitters.
Some tips for establishing reasonable expectations for babysitters include:
- Set clear expectations: Sit down with your babysitter to discuss bedtime routines, dietary preferences, and any necessary medications.
- Allow flexibility: While clarity is vital, also provide room for your babysitter to use their judgment and feel comfortable in their role.
- Trust their expertise: Once expectations are set, trust your babysitter’s judgment as a professional caregiver to avoid undermining their authority and creating discomfort in their role.
Determining a Fair Payment Plan
Determine your babysitting budget, factoring in your income and family size, while researching local rates. Account for the babysitter’s experience and qualifications, giving preference to those recommended by trusted sources.
Engage in open negotiations with your chosen babysitter. This aims to find a mutually agreeable arrangement that accommodates both your budget and their needs.
Tips on Finding Trustworthy and Compassionate Caregivers
When seeking a caregiver for your child, to ensure you find the right fit:
- Seek recommendations from trusted sources such as friends, family, and neighbours who may have suggestions for caregivers in your area.
- Conduct online research to review feedback and check references to gauge candidates’ qualifications and experience.
- Request references and contact details from the caregivers’ previous employers or families they have worked with.
- Trust your instincts and ensure you feel at ease with the caregiver, ensuring they are someone you can entrust with your child’s well-being.
Being able to trust your babysitter means you can have peace of mind knowing your child is safe and cared for.
Spending some time researching online reviews or asking friends and family for recommendations will help you find the perfect fit so you can feel more at ease while juggling work commitments in today’s hectic world.
Facility-wide COVID-19 outbreak at Bethammi Nursing Home
THUNDER BAY — St. Joseph’s Care Group and the Thunder Bay District Health Unit have declared a facility-wide COVID-19 outbreak at Bethammi Nursing Home, part of the St. Joseph’s Heritage complex on Carrie Street near Red River Road.
The respiratory outbreak at the 112-bed facility was declared effective Sept. 15 but only announced publicly on Monday.
No details were provided with regard to the number of people affected to date.
Restrictions are now in place for admissions, transfers, discharges, social activities and visitation until further notice.
Alberta COVID hospitalizations up 73% since July: health minister
Three weeks after the start of the school year, Alberta’s health minister provided an update on the spread of airborne viruses in the province.
Adriana LaGrange also said more information about flu and next-generation COVID-19 vaccines will soon be released.
“Now that we will be spending more time indoors, we need to make doubly sure we are following proper hygiene protocols like handwashing and staying home when sick,” LaGrange said. “It also means respecting those who choose to wear a mask.”
Global News previously reported that influenza vaccines will be available on Oct. 16 with the new Moderna vaccine formulated to target the XBB.1.5 variant likely to be available at around the same time. On Sept. 12, Health Canada approved the use of the Moderna vaccine.
“More information on immunizations against respiratory viruses including influenza and COVID-19 will be available shortly,” the health minister said.
LaGrange said there have been 28 cases of influenza and five lab-confirmed cases of respiratory syncytial virus (RSV) since Aug. 28.
“This is consistent activity for this time of the year,” the health minister said in a statement.
The end of August or the beginning of September has typically marked the beginning of flu season for provincial health authorities.
LaGrange also provided an update on the ongoing COVID-19 pandemic in the province.
From Aug. 28 to Sept. 8, there were a total 92 new hospitalizations and three ICU admissions, bringing the total to 417 in hospital and seven in ICU, a 73 per cent increase of COVID hospitalizations from the last reported info.
On July 24 – the last update to the province’s COVID data dashboard – there were only 242 in hospital.
“Sadly, five Albertans died during that period due to COVID-19,” LaGrange said.
LaGrange said the reporting dashboard is being refreshed to include RSV, influenza and COVID-19 data, work that was originally expected to be completed on Aug. 30. The latest data on the province’s influenza statistics dashboard is dated July 22.
“This work is currently underway and will be available in the coming weeks,” LaGrange said.
She said data for the dates between July 24 and Aug. 27 will be available when the new dashboard goes online.
Amid more hospitals continent-wide reinstating masking requirements in the face of increased hospitalizations, the health minister made no mention of any such moves for Alberta hospitals. Acute care COVID-19 outbreaks in Alberta jumped from Sept. 5 to 12, with 146 per cent more healthcare workers and 55 per cent more patients testing positive for COVID.
LaGrange stressed the “collective responsibility” to prevent the spread of airborne viruses like COVID and influenza.
“As a mother and grandmother, I understand the anxiety that comes with sending your children back to school. I want to reassure you that Alberta’s government has the health and well-being of all young Albertans top of mind,” the health minister said.
