Paxlovid does not significantly alleviate symptoms of COVID-19 compared with placebo among nonhospitalized adults, a new study published April 3 in The New England Journal of Medicine found. 

The results suggest that the drug, a combination of nirmatrelvir and ritonavir, may not be particularly helpful for patients who are not at high risk for severe COVID-19. However, although the rate of hospitalization and death from any cause was low overall, the group that received Paxlovid had a reduced rate compared with people in the placebo group, according to the researchers. 

“Clearly, the benefit observed among unvaccinated high-risk persons does not extend to those at lower risk for severe COVID-19,” Rajesh T. Gandhi, MD, and Martin Hirsch, MD, of Massachusetts General Hospital in Boston, wrote in an editorial accompanying the journal article. “This result supports guidelines that recommend nirmatrelvir–ritonavir only for persons who are at high risk for disease progression.”

The time from onset to relief of COVID-19 symptoms — including cough, shortness of breath, body aches, and chills — did not differ significantly between the two study groups, the researchers reported. The median time to sustained alleviation of symptoms was 12 days for the Paxlovid group compared with 13 days in the placebo group (P = .60).

However, the phase 2/3 trial found a 57.6% relative reduction in the risk for hospitalizations or death among people who took Paxlovid and were vaccinated but were at high risk for poor outcomes, according to Jennifer Hammond, PhD, head of antiviral development for Pfizer, which makes the drug, and the corresponding author on the study.

Paxlovid has “an increasing body of evidence supporting the strong clinical value of the treatment in preventing hospitalization and death among eligible patients across age groups, vaccination status, and predominant variants,” Dr. Hammond said. 

She and her colleagues analyzed data from 1250 adults with symptomatic COVID-19. Participants were fully vaccinated and had a high risk for progression to severe disease or were never vaccinated or had not been in the previous year and had no risk factors for progression to severe disease.

More than half of participants were women, 78.5% were White and 41.4% identified as Hispanic or Latinx. Almost three quarters underwent randomization within 3 days of the start of symptoms, and a little over half had previously received a COVID-19 vaccination. Almost half had one risk factor for severe illness, the most common of these being hypertension (12.3%). 

In a subgroup analysis of high-risk participants, hospitalization or death occurred in 0.9% of patients in the Paxlovid group and 2.2% in the placebo group (95% CI, -3.3 to 0.7). 

The study’s limitations include that the statistical analysis of COVID-19–related hospitalizations or death from any cause was only descriptive, “because the results for the primary efficacy end point were not significant,” the authors wrote. 

Participants who were vaccinated and at high risk were also enrolled regardless of when they had last had a vaccine dose. Furthermore, Paxlovid has a telltale taste, which may have affected the blinding. Finally, the trial was started when the B.1.617.2 (Delta) variant was predominant.

Dr. Gandhi and Dr. Hirsch pointed out that only 5% of participants in the trial were older than 65 years and that other than risk factors such as obesity and smoking, just 2% of people had heart or lung disease. 

“As with many medical interventions, there is likely to be a gradient of benefit for nirmatrelvir–ritonavir, with the patients at highest risk for progression most likely to derive the greatest benefit,” Dr. Gandhi and Dr. Hirsch wrote in the editorial. “Thus, it appears reasonable to recommend nirmatrelvir–ritonavir primarily for the treatment of COVID-19 in older patients (particularly those ≥ 65 years of age), those who are immunocompromised, and those who have conditions that substantially increase the risk of severe COVID-19, regardless of previous vaccination or infection status.”

The study was supported by Pfizer.

TOPLINE: 

There were few cases of SARS-CoV-2 infections among emergency department (ED) healthcare personnel and no substantial changes in the delivery of emergency medical care during the initial phase of the COVID-19 pandemic.

METHODOLOGY:

• This multicenter prospective cohort study of US ED healthcare personnel called Project COVERED was conducted from May to December 2020 to evaluate the following outcomes:
• The possibility of infected ED personnel reporting to work
• The burden of COVID-19 symptoms on an ED personnel’s work status
• The association between SARS-CoV-2 infection levels and ED staffing
• Project COVERED enrolled 1673 ED healthcare personnel with 29,825 person weeks of observational data from 25 geographically diverse EDs.
• The presence of any SARS-CoV-2 infection was determined using reverse transcription polymerase chain reaction or IgG antibody testing at baseline, week 2, week 4, and every four subsequent weeks through week 20.
• Investigators also collected weekly data on ED staffing and the incidence of SARS-CoV-2 infections in healthcare facilities.

TAKEAWAY:

• Despite the absence of widespread natural immunity or COVID-19 vaccine availability during the time of this study, only 4.5% of ED healthcare personnel tested positive for SARS-CoV-2 infections, with more than half (57.3%) not experiencing any symptoms.
• Most personnel (83%) who experienced symptoms associated with COVID-19 reported working at least one shift in the ED and nearly all of them continued to work until they received laboratory confirmation of their infection.
• The working time lost as a result of COVID-19 and related concerns was minimal, as 89 healthcare personnel reported 90 person weeks of missed work (0.3% of all weeks).
• During this study, physician-staffing levels ranged from 98.7% to 102.0% of normal staffing, with similar values noted for nursing and nonclinical staffs. Reduced staffing was rare, even during COVID-19 surges.

IN PRACTICE:

“Our findings suggest that the cumulative interaction between infected healthcare personnel and others resulted in a negligible risk of transmission on the scale of public health emergencies,” the authors wrote.

SOURCE:

This study was led by Kurt D. Weber, MD, Department of Emergency Medicine, Orlando Health, Orlando, Florida, and published online in Annals of Emergency Medicine.

LIMITATIONS:

Data regarding the Delta variant surges that occurred toward the end of December and the ED status after the advent of the COVID-19 vaccine were not recorded. There may also have been a selection bias risk in this study because the volunteer participants may have exhibited behaviors like social distancing and use of protective equipment, which may have decreased their risk for infections.

DISCLOSURES:

This study was funded by a cooperative agreement from the Centers for Disease Control and Prevention and the Institute for Clinical and Translational Science at the University of Iowa through a grant from the National Center for Advancing Translational Sciences at the National Institutes of Health. The authors declared no conflicts of interest.

Weight loss drugs have surged in popularity — in part because they work. Patients on glucagon-like peptide 1 (GLP-1) agonists like liraglutide, semaglutide, and tirzepatide (which is technically also a glucose-dependent insulinotropic polypeptide agonist) can lose 10%, 20%, or even 25% of their body weight.

But if those patients stop taking GLP-1s, they tend to regain most of that weight within a year, studies showed.

“These drugs work inside the person from a biologic point of view to alter appetite,” said Robert Kushner, MD, an endocrinologist and professor at Northwestern University Feinberg School of Medicine, Chicago, Illinois, who specializes in obesity medicine. “And when the drug is gone, that disease comes back.” 

Ongoing treatment may seem like the obvious solution, but reality can complicate that. High costs, supply shortages, and faltering insurance coverage can render the drugs inaccessible.

Often, “patients are told by their insurers that they are no longer going to cover a GLP-1 for obesity,” said Carolyn Bramante, MD, MPH, an assistant professor at the University of Minnesota Medical School, Minneapolis, Minnesota, who sees patients at the M Health Fairview weight management clinic.

Other barriers include side effects like nausea, diarrhea, stomach pain, and vomiting. Some patients simply don’t want to take a medication forever, instead choosing to take their chances keeping the weight off sans drug.

If your patient must stop GLP-1s, or really wants to, here’s how to help.

Find out why the patient wants to go off the GLP-1. Ask them to help you understand, suggested Jaime Almandoz, MD, associate professor of internal medicine and medical director of the University of Texas Southwestern Medical Center’s Weight Wellness Program. Sometimes, the patient or family members worry about safety, Dr. Almandoz said. “They may be concerned about the risks and may not have had an opportunity to ask questions.” Dr. Almandoz reviews the drug safety data and tells patients that studies show, on average, people gain back two-thirds of the weight they’ve lost within a year. You’re not trying to persuade them, only to equip them to make a well-informed choice.

Don’t let bias affect treatment decisions. Patients on GLP-1s often ask: How long will I have to take this? The reason: “We’re biased to believe that this is not a disease state, that this is a character flaw,” said Sean Wharton, MD, PharmD, medical director of the Wharton Medical Clinic for weight management in Burlington, Ontario, Canada. Remind your patient that obesity is not a personal failure but rather a complex mix of genetic and biological factors.

Give patients a primer on the biology of obesity. Science shows that when we lose weight, our bodies fight back, trying to return to our highest-ever fat mass. Changes in neurohormones, gut hormones, satiety mechanisms, metabolism, and muscle function all converge to promote weight recurrence, Dr. Almandoz said. To explain this to patients, Dr. Almandoz compares gaining fat to depositing money in a savings account. “When we try to lose weight, it isn’t as simple as withdrawing this money,” he’ll tell them. “It is almost like the money that we put into the savings account is now tied up in investments that we can’t liquidate easily.”

Prepare patients for an uptick in appetite. When patients stop GLP-1s, their hunger and food cravings tend to increase. “I explain that GLP-1 medications mimic a hormone that is released from our intestines when they sense we have eaten,” said Dr. Almandoz. This signals the brain and body that food is on board, decreasing appetite and cravings. Ask patients what hungry and full feel like on the medication, Dr. Almandoz suggested. “Many will report that their hunger and cravings are low, that they now have an indifference to foods,” said Dr. Almandoz. Such probing questions can help patients be more aware of the medication’s effects. “This positions a more informed conversation if medications are to be discontinued,” Dr. Almandoz said.

Help their body adjust. “Slowly wean down on the dose, if possible, to avoid a big rebound in hunger,” said Dr. Bramante. If your patient has the time — say, they received a letter from their insurance that coverage will end in 3 months — use it to taper the dose as low as possible before stopping. The slower and more gradual, the better. Dr. Almandoz checks in with patients every 4-8 weeks. If they›re maintaining weight well, he considers decreasing the dose again and repeating with follow-up visits.

Substitute one intervention for another. In general, maintaining weight loss requires some intervention, Dr. Wharton said. “But that intervention does not need to be the same as the intervention that got the weight down.” If the patient can›t continue a GLP-1, consider an alternate medication, cognitive behavioral therapy, or a combination of the two. When patients lose coverage for GLP-1s, Dr. Bramante sometimes prescribes an older, less-expensive weight loss drug, such as phentermine, topiramate, or metformin. And sometimes, insurers that don’t cover GLP-1s (like Medicare), do cover bariatric surgery, a potential option depending on the patient›s body mass index, overall health, and comorbidities, said Dr. Almandoz.

Create a habit template. Dr. Kushner asks patients who have successfully lost weight to take an inventory of everything they’re doing to support their efforts. He’ll have them describe how they plan their diet, what types of food they’re eating, how much they eat, and when they eat it. He’ll also ask about physical activity, exercise patterns, and sleep. He logs all the habits into a bulleted list in the patient’s after-visit summary and hands them a printout before they leave. “That’s your template,” he’ll tell them. “That’s what you’re going to try to maintain to the best of your ability because it’s working for you.”

Prescribe exercise. “Increasing exercise is not usually effective for initial weight loss, but it is important for maintaining weight loss,” said Dr. Bramante. Tell patients to start right away, ideally while they’re still on the drug. In a study published last month, patients on liraglutide (Saxenda) who exercised 4 days a week were much more likely to keep weight off after stopping the drug than those who didn’t work out. (The study was partially funded by Novo Nordisk Foundation, the charitable arm of Saxenda’s maker, also the maker of semaglutide meds Ozempic and Wegovy.) By establishing strong exercise habits while on the medication, they were able to sustain higher physical activity levels after they stopped. Ask your patient to identify someone or something to help them stick to their plan, “whether it’s seeing a personal trainer or being accountable to a friend or family member or to themselves through record keeping,” said Dr. Kushner. Learn more about how to prescribe exercise to patients here.

Help them create a “microenvironment” for success. Dr. Kushner asks patients which of the recommended dietary habits for weight loss are hardest to follow: Eating more plant-based foods? Cutting back on ultra-processed foods, fatty foods, fast foods, and/or sugary beverages? Depending on the patient’s answers, he tries to recommend strategies — maybe going meatless a few days a week or keeping tempting foods out of the house. “If you go off medication, food may become more enticing, and you may not feel as content eating less,” Dr. Kushner said. “Make sure your own what we call microenvironment, your home environment, is filled with healthy foods.”

Rely on multidisciplinary expertise. Obesity is a complex, multifactorial disease, so call in reinforcements. “When I see someone, I’m always evaluating what other team members they would benefit from,” said Dr. Kushner. If the patient lacks nutrition knowledge, he refers them to a registered dietitian. If they struggle with self-blame, low self-esteem, and emotional eating, he’ll refer them to a psychologist. It can make a difference: A 2023 study showed that people who lost weight and received support from professionals like trainers, dietitians, and mental health therapists regained less weight over 2 years than those who did not receive the same help.

Reassure patients you will help them no matter what. Ask patients to follow-up within the first month of quitting medication or to call back sooner if they gain 5 pounds. People who stop taking GLP-1s often report less satisfaction with eating, or that they think about food more. That’s when Dr. Kushner asks whether they want to go back on the medication or focus on other strategies. Sometimes, patients who gain weight feel embarrassed and delay their follow-up visits. If that happens, welcome them back and let them know that all chronic conditions ebb and flow. “I constantly remind them that I am here to help you, and there are many tools or resources that will help you,” Dr. Kushner said. “And dispel the notion that it’s somehow your fault.”

Dr. Kushner reported participation on the medical advisory board or consultancy with Novo Nordisk, WeightWatchers, Eli Lilly and Company, Boehringer Ingelheim, Structure Therapeutics, and Altimmune. He added he does not own stock or participate in any speaker’s bureau. Dr. Almandoz reported participation on advisory boards with Novo Nordisk, Boehringer Ingelheim, and Eli Lilly and Company. Dr. Wharton reported participation on advisory boards and honoraria for academic talks and clinical research with Novo Nordisk, Eli Lilly and Company, Boehringer Ingelheim, Amgen, Regeneron, and BioHaven.

Substitute one intervention for another. In general, maintaining weight loss requires some intervention, Dr. Wharton said. “But that intervention does not need to be the same as the intervention that got the weight down.” If the patient can›t continue a GLP-1, consider an alternate medication, cognitive behavioral therapy, or a combination of the two. When patients lose coverage for GLP-1s, Dr. Bramante sometimes prescribes an older, less-expensive weight loss drug, such as phentermine, topiramate, or metformin. And sometimes, insurers that don’t cover GLP-1s (like Medicare), do cover bariatric surgery, a potential option depending on the patient›s body mass index, overall health, and comorbidities, said Dr. Almandoz.

Create a habit template. Dr. Kushner asks patients who have successfully lost weight to take an inventory of everything they’re doing to support their efforts. He’ll have them describe how they plan their diet, what types of food they’re eating, how much they eat, and when they eat it. He’ll also ask about physical activity, exercise patterns, and sleep. He logs all the habits into a bulleted list in the patient’s after-visit summary and hands them a printout before they leave. “That’s your template,” he’ll tell them. “That’s what you’re going to try to maintain to the best of your ability because it’s working for you.”

Prescribe exercise. “Increasing exercise is not usually effective for initial weight loss, but it is important for maintaining weight loss,” said Dr. Bramante. Tell patients to start right away, ideally while they’re still on the drug. In a study published last month, patients on liraglutide (Saxenda) who exercised 4 days a week were much more likely to keep weight off after stopping the drug than those who didn’t work out. (The study was partially funded by Novo Nordisk Foundation, the charitable arm of Saxenda’s maker, also the maker of semaglutide meds Ozempic and Wegovy.) By establishing strong exercise habits while on the medication, they were able to sustain higher physical activity levels after they stopped. Ask your patient to identify someone or something to help them stick to their plan, “whether it’s seeing a personal trainer or being accountable to a friend or family member or to themselves through record keeping,” said Dr. Kushner.

Help them create a “microenvironment” for success. Dr. Kushner asks patients which of the recommended dietary habits for weight loss are hardest to follow: Eating more plant-based foods? Cutting back on ultra-processed foods, fatty foods, fast foods, and/or sugary beverages? Depending on the patient’s answers, he tries to recommend strategies — maybe going meatless a few days a week or keeping tempting foods out of the house. “If you go off medication, food may become more enticing, and you may not feel as content eating less,” Dr. Kushner said. “Make sure your own what we call microenvironment, your home environment, is filled with healthy foods.”

Rely on multidisciplinary expertise. Obesity is a complex, multifactorial disease, so call in reinforcements. “When I see someone, I’m always evaluating what other team members they would benefit from,” said Dr. Kushner. If the patient lacks nutrition knowledge, he refers them to a registered dietitian. If they struggle with self-blame, low self-esteem, and emotional eating, he’ll refer them to a psychologist. It can make a difference: A 2023 study showed that people who lost weight and received support from professionals like trainers, dietitians, and mental health therapists regained less weight over 2 years than those who did not receive the same help.

Reassure patients you will help them no matter what. Ask patients to follow-up within the first month of quitting medication or to call back sooner if they gain 5 pounds. People who stop taking GLP-1s often report less satisfaction with eating, or that they think about food more. That’s when Dr. Kushner asks whether they want to go back on the medication or focus on other strategies. Sometimes, patients who gain weight feel embarrassed and delay their follow-up visits. If that happens, welcome them back and let them know that all chronic conditions ebb and flow. “I constantly remind them that I am here to help you, and there are many tools or resources that will help you,” Dr. Kushner said. “And dispel the notion that it’s somehow your fault.”

Dr. Kushner reported participation on the medical advisory board or consultancy with Novo Nordisk, WeightWatchers, Eli Lilly and Company, Boehringer Ingelheim, Structure Therapeutics, and Altimmune. He added he does not own stock or participate in any speaker’s bureau. Dr. Almandoz reported participation on advisory boards with Novo Nordisk, Boehringer Ingelheim, and Eli Lilly and Company. Dr. Wharton reported participation on advisory boards and honoraria for academic talks and clinical research with Novo Nordisk, Eli Lilly and Company, Boehringer Ingelheim, Amgen, Regeneron, and BioHaven.

Weight loss drugs have surged in popularity — in part because they work. Patients on glucagon-like peptide 1 (GLP-1) agonists like liraglutide, semaglutide, and tirzepatide (which is technically also a glucose-dependent insulinotropic polypeptide agonist) can lose 10%, 20%, or even 25% of their body weight.

But if those patients stop taking GLP-1s, they tend to regain most of that weight within a year, studies showed.

“These drugs work inside the person from a biologic point of view to alter appetite,” said Robert Kushner, MD, an endocrinologist and professor at Northwestern University Feinberg School of Medicine, Chicago, Illinois, who specializes in obesity medicine. “And when the drug is gone, that disease comes back.” 

Ongoing treatment may seem like the obvious solution, but reality can complicate that. High costs, supply shortages, and faltering insurance coverage can render the drugs inaccessible.

Often, “patients are told by their insurers that they are no longer going to cover a GLP-1 for obesity,” said Carolyn Bramante, MD, MPH, an assistant professor at the University of Minnesota Medical School, Minneapolis, Minnesota, who sees patients at the M Health Fairview weight management clinic.

Other barriers include side effects like nausea, diarrhea, stomach pain, and vomiting. Some patients simply don’t want to take a medication forever, instead choosing to take their chances keeping the weight off sans drug.

If your patient must stop GLP-1s, or really wants to, here’s how to help.

Find out why the patient wants to go off the GLP-1. Ask them to help you understand, suggested Jaime Almandoz, MD, associate professor of internal medicine and medical director of the University of Texas Southwestern Medical Center’s Weight Wellness Program. Sometimes, the patient or family members worry about safety, Dr. Almandoz said. “They may be concerned about the risks and may not have had an opportunity to ask questions.” Dr. Almandoz reviews the drug safety data and tells patients that studies show, on average, people gain back two-thirds of the weight they’ve lost within a year. You’re not trying to persuade them, only to equip them to make a well-informed choice.

Don’t let bias affect treatment decisions. Patients on GLP-1s often ask: How long will I have to take this? The reason: “We’re biased to believe that this is not a disease state, that this is a character flaw,” said Sean Wharton, MD, PharmD, medical director of the Wharton Medical Clinic for weight management in Burlington, Ontario, Canada. Remind your patient that obesity is not a personal failure but rather a complex mix of genetic and biological factors.

Give patients a primer on the biology of obesity. Science shows that when we lose weight, our bodies fight back, trying to return to our highest-ever fat mass. Changes in neurohormones, gut hormones, satiety mechanisms, metabolism, and muscle function all converge to promote weight recurrence, Dr. Almandoz said. To explain this to patients, Dr. Almandoz compares gaining fat to depositing money in a savings account. “When we try to lose weight, it isn’t as simple as withdrawing this money,” he’ll tell them. “It is almost like the money that we put into the savings account is now tied up in investments that we can’t liquidate easily.”

Prepare patients for an uptick in appetite. When patients stop GLP-1s, their hunger and food cravings tend to increase. “I explain that GLP-1 medications mimic a hormone that is released from our intestines when they sense we have eaten,” said Dr. Almandoz. This signals the brain and body that food is on board, decreasing appetite and cravings. Ask patients what hungry and full feel like on the medication, Dr. Almandoz suggested. “Many will report that their hunger and cravings are low, that they now have an indifference to foods,” said Dr. Almandoz. Such probing questions can help patients be more aware of the medication’s effects. “This positions a more informed conversation if medications are to be discontinued,” Dr. Almandoz said.

Help their body adjust. “Slowly wean down on the dose, if possible, to avoid a big rebound in hunger,” said Dr. Bramante. If your patient has the time — say, they received a letter from their insurance that coverage will end in 3 months — use it to taper the dose as low as possible before stopping. The slower and more gradual, the better. Dr. Almandoz checks in with patients every 4-8 weeks. If they›re maintaining weight well, he considers decreasing the dose again and repeating with follow-up visits.

Substitute one intervention for another. In general, maintaining weight loss requires some intervention, Dr. Wharton said. “But that intervention does not need to be the same as the intervention that got the weight down.” If the patient can›t continue a GLP-1, consider an alternate medication, cognitive behavioral therapy, or a combination of the two. When patients lose coverage for GLP-1s, Dr. Bramante sometimes prescribes an older, less-expensive weight loss drug, such as phentermine, topiramate, or metformin. And sometimes, insurers that don’t cover GLP-1s (like Medicare), do cover bariatric surgery, a potential option depending on the patient›s body mass index, overall health, and comorbidities, said Dr. Almandoz.

TOPLINE: 

The spices and aromatic herbs of the Mediterranean diet with significant benefits in improving glycemic health in type 2 diabetes are limited to ginger, cinnamon, black cumin, turmeric, and saffron, with ginger, black cumin, and cinnamon having the strongest effects on fasting glucose, according to a systematic review and meta-analysis of research.

The meta-analysis also evaluated clove, thyme, turmeric, and various other spices and herbs common in the diet but showed no other correlations with glycemic benefits. 

METHODOLOGY:

• In the analysis of 77 studies, 45, involving 3050 participants, were included in the meta-analysis and 32 studies in the systematic review.
• The studies’ inclusion criteria included adult patients with type 2 diabetes, with data on fasting glucose and/or A1c and/or , and involving any supplementation with black cumin, clove, , saffron, thyme, ginger, black pepper, , curcumin, cinnamon, basil, and/or oregano.
• The number of studies involving clove, parsley, thyme, black pepper, rosemary, basil, or oregano and their association with glycemic factors in people with type 2 diabetes was insufficient, hence the analysis primarily focused on the remaining five ingredients of cinnamon, curcumin, ginger, black cumin, saffron, and rosemary.

TAKEAWAY: 

• Improvements in fasting glucose of subjects with type 2 diabetes were observed with all five ingredients of cinnamon, turmeric, ginger, black cumin, and saffron.
• However, the most significant decreases in fasting glucose, between 17 mg/dL and 27 mg/dL, occurred after supplementation with black cumin, followed by cinnamon and ginger.
• Notably, only ginger and black cumin were associated with a significant improvement in A1c.
• Only cinnamon and ginger were associated with a significant decrease in insulin values.
• Of the 11 studies including cinnamon in the meta-analysis, 6 reported significant differences in fasting glucose, while 4 had differences in A1c after the supplementation.
• However, ginger was the only component associated with a significant decrease in each of the 3 outcomes examined of fasting glucose, A1c, and insulin.

IN PRACTICE:

“The Mediterranean Diet is the dietary pattern par excellence for managing and preventing metabolic diseases, such as type 2 diabetes,” the authors reported.

“As far as we are aware, this is the first systematic review and meta-analysis aiming to evaluate the effect of aromatic herbs and spices included in the Mediterranean Diet, such as black cumin, clove [and others], on the glycemic profile of individuals with type 2 diabetes,” they added.

“When focusing on HbA1c, only ginger and black cumin demonstrated therapeutic effects,” the authors noted. “However, our meta-analysis highlights ginger as an herb with substantial translational potential for diabetes treatment, impacting all three glycemic parameters.”

“Regarding clove, parsley, thyme, black pepper, rosemary, basil, and oregano, more studies are needed to analyze the effect of these herbs on the glycemic profile in type 2 diabetes subjects,” the authors concluded.

SOURCE:

The study was published on March 7, 2024, in Nutrients. The first author was Maria Carmen Garza, PhD, of the Department of Human Anatomy and Histology, School Medicine, University of Zaragoza, Zaragoza, Spain.

LIMITATIONS:

Despite the results, a variety of other factors can affect fasting glucose levels, including changes in body weight or body mass index, as well as the combination of spice or aromatic herb supplementation with physical activity or lifestyle changes, the authors noted.

Due to the studies’ differences, the determination of effective dosages of the herbs and spices was not possible.

Furthermore, the studies had wide variations in quality, with few studies including adequate statistical analysis.

DISCLOSURES:

The authors had no disclosures to report.

A new study from the United Kingdom provides greater clarity on how SARS-CoV-2 infection can affect cognition and memory, including novel data on how long brain fog may last after the illness resolves and which cognitive functions are most vulnerable. 

In a large community sample, researchers found that on average, people who had recovered from COVID-19 showed small cognitive deficits equivalent to a 3-point loss in IQ for up to 1 year or more after recovering from the acute illness compared with peers who never had COVID-19.

However, people who had more severe cases, requiring treatment in a hospital intensive care unit, had cognitive deficits equivalent to a 9-point drop in IQ.

“People with ongoing persistent symptoms, indicative of long COVID, had larger cognitive deficits than people whose symptoms had resolved,” first author Adam Hampshire, PhD, with Imperial College London, London, England, told this news organization. 

The largest deficits among cognitive tasks were in memory, reasoning, and executive function, he added.

“That is, people who had had COVID-19 were both slower and less accurate when performing tasks that measure those abilities,” Dr. Hampshire said. “The group with the largest cognitive deficits were patients who had been in intensive care for COVID-19.”

The study was published online in The New England Journal of Medicine. 
 

Lingering Brain Fog

Cognitive symptoms after SARS-CoV-2 infection are well recognized, but whether objectively measurable cognitive deficits exist and how long they persist remains unclear. 

To investigate, researchers invited 800,000 adults from the REACT study of SARS-CoV-2 transmission in England to complete an online assessment for cognitive function with eight domains.

Altogether, 141,583 participants started the cognitive battery by completing at least one task, and 112,964 completed all eight tasks.

The researchers estimated global cognitive scores among participants who had been previously infected with SARS-CoV-2 with symptoms that persisted for at least 12 weeks, whether or not resolved, and among uninfected participants. 

Compared with uninfected adults, those who had COVID-19 that resolved had a small cognitive deficit, corresponding to a 3-point loss in IQ, the researchers found. 

Adults with unresolved persistent COVID-19 symptoms had the equivalent of a 6-point loss in IQ, and those who had been admitted to the intensive care unit had the equivalent of a 9-point loss in IQ, in line with previous findings of cognitive deficits in patients hospitalized in a critical care unit, the researchers report. 

Larger cognitive deficits were evident in adults infected early in the pandemic by the original SARS-CoV-2 virus or the B.1.1.7 variant, whereas peers infected later in the pandemic (eg., in the Omicron period), showed smaller cognitive deficits. This finding is in line with other studies suggesting that the association between COVID-19–associated cognitive deficits attenuated as the pandemic progressed, the researchers noted. 

They also found that people who had COVID-19 after receiving two or more vaccinations showed better cognitive performance compared with those who had not been vaccinated. 

The memory, reasoning, and executive function tasks were among the most sensitive to COVID-19–related cognitive differences and performance on these tasks differed according to illness duration and hospitalization. 

Dr. Hampshire said that more research is needed to determine whether the cognitive deficits resolve with time. 

“The implications of longer-term persistence of cognitive deficits and their clinical relevance remain unclear and warrant ongoing surveillance,” he said.

 

Larger Cognitive Deficits Likely?

These results are “a concern and the broader implications require evaluation,” wrote Ziyad Al-Aly, MD, with Washington University School of Medicine in St. Louis, Missouri, and Clifford Rosen, MD, with Tufts University School of Medicine in Boston, Massachusetts, in an accompanying editorial. 

In their view, several outstanding questions remain, including what the potential functional implications of a 3-point loss in IQ may be and whether COVID-19–related cognitive deficits predispose to a higher risk for dementia later in life. 

“A deeper understanding of the biology of cognitive dysfunction after SARS-CoV-2 infection and how best to prevent and treat it are critical for addressing the needs of affected persons and preserving the cognitive health of populations,” Drs. Al-Aly and Rosen concluded. 

Commenting on the study for this news organization, Jacqueline Becker, PhD, clinical neuropsychologist and assistant professor of medicine, Icahn School of Medicine at Mount Sinai, New York City, noted that “one important caveat” is that the study used an online assessment tool for cognitive function and therefore the findings should be taken with “a grain of salt.”

“That said, this is a large sample, and the findings are generally consistent with what we’ve seen in terms of cognitive deficits post-COVID,” Dr. Becker said. 

It’s likely that this study “underestimates” the degree of cognitive deficits that would be seen on validated neuropsychological tests, she added.

In a recent study, Dr. Becker and her colleagues investigated rates of cognitive impairment in 740 COVID-19 patients who recovered and were treated in outpatient, emergency department, or inpatient hospital settings. 

Using validated neuropsychological measures, they found a relatively high frequency of cognitive impairment several months after patients contracted COVID-19. Impairments in executive functioning, processing speed, category fluency, memory encoding, and recall were predominant among hospitalized patients. 

Dr. Becker noted that in her experience, cognition typically will improve in some patients 12-18 months post COVID. 

Support for the study was provided by the National Institute for Health and Care Research and UK Research and Innovation and by the Department of Health and Social Care in England and the Huo Family Foundation.

In their view, several outstanding questions remain, including what the potential functional implications of a 3-point loss in IQ may be and whether COVID-19–related cognitive deficits predispose to a higher risk for dementia later in life. 

“A deeper understanding of the biology of cognitive dysfunction after SARS-CoV-2 infection and how best to prevent and treat it are critical for addressing the needs of affected persons and preserving the cognitive health of populations,” Drs. Al-Aly and Rosen concluded. 

Commenting on the study for this news organization, Jacqueline Becker, PhD, clinical neuropsychologist and assistant professor of medicine, Icahn School of Medicine at Mount Sinai, New York City, noted that “one important caveat” is that the study used an online assessment tool for cognitive function and therefore the findings should be taken with “a grain of salt.”

“That said, this is a large sample, and the findings are generally consistent with what we’ve seen in terms of cognitive deficits post-COVID,” Dr. Becker said. 

It’s likely that this study “underestimates” the degree of cognitive deficits that would be seen on validated neuropsychological tests, she added.

In a recent study, Dr. Becker and her colleagues investigated rates of cognitive impairment in 740 COVID-19 patients who recovered and were treated in outpatient, emergency department, or inpatient hospital settings. 

Using validated neuropsychological measures, they found a relatively high frequency of cognitive impairment several months after patients contracted COVID-19. Impairments in executive functioning, processing speed, category fluency, memory encoding, and recall were predominant among hospitalized patients. 

Dr. Becker noted that in her experience, cognition typically will improve in some patients 12-18 months post COVID. 

Support for the study was provided by the National Institute for Health and Care Research and UK Research and Innovation and by the Department of Health and Social Care in England and the Huo Family Foundation.

A new study from the United Kingdom provides greater clarity on how SARS-CoV-2 infection can affect cognition and memory, including novel data on how long brain fog may last after the illness resolves and which cognitive functions are most vulnerable. 

In a large community sample, researchers found that on average, people who had recovered from COVID-19 showed small cognitive deficits equivalent to a 3-point loss in IQ for up to 1 year or more after recovering from the acute illness compared with peers who never had COVID-19.

However, people who had more severe cases, requiring treatment in a hospital intensive care unit, had cognitive deficits equivalent to a 9-point drop in IQ.

“People with ongoing persistent symptoms, indicative of long COVID, had larger cognitive deficits than people whose symptoms had resolved,” first author Adam Hampshire, PhD, with Imperial College London, London, England, told this news organization. 

The largest deficits among cognitive tasks were in memory, reasoning, and executive function, he added.

“That is, people who had had COVID-19 were both slower and less accurate when performing tasks that measure those abilities,” Dr. Hampshire said. “The group with the largest cognitive deficits were patients who had been in intensive care for COVID-19.”

The study was published online in The New England Journal of Medicine. 
 

Lingering Brain Fog

Cognitive symptoms after SARS-CoV-2 infection are well recognized, but whether objectively measurable cognitive deficits exist and how long they persist remains unclear. 

To investigate, researchers invited 800,000 adults from the REACT study of SARS-CoV-2 transmission in England to complete an online assessment for cognitive function with eight domains.

Altogether, 141,583 participants started the cognitive battery by completing at least one task, and 112,964 completed all eight tasks.

The researchers estimated global cognitive scores among participants who had been previously infected with SARS-CoV-2 with symptoms that persisted for at least 12 weeks, whether or not resolved, and among uninfected participants. 

Compared with uninfected adults, those who had COVID-19 that resolved had a small cognitive deficit, corresponding to a 3-point loss in IQ, the researchers found. 

Adults with unresolved persistent COVID-19 symptoms had the equivalent of a 6-point loss in IQ, and those who had been admitted to the intensive care unit had the equivalent of a 9-point loss in IQ, in line with previous findings of cognitive deficits in patients hospitalized in a critical care unit, the researchers report. 

Larger cognitive deficits were evident in adults infected early in the pandemic by the original SARS-CoV-2 virus or the B.1.1.7 variant, whereas peers infected later in the pandemic (eg., in the Omicron period), showed smaller cognitive deficits. This finding is in line with other studies suggesting that the association between COVID-19–associated cognitive deficits attenuated as the pandemic progressed, the researchers noted. 

They also found that people who had COVID-19 after receiving two or more vaccinations showed better cognitive performance compared with those who had not been vaccinated. 

The memory, reasoning, and executive function tasks were among the most sensitive to COVID-19–related cognitive differences and performance on these tasks differed according to illness duration and hospitalization. 

Dr. Hampshire said that more research is needed to determine whether the cognitive deficits resolve with time. 

“The implications of longer-term persistence of cognitive deficits and their clinical relevance remain unclear and warrant ongoing surveillance,” he said.

Scientists at the University of California, San Francisco, have discovered that remnants of the COVID-19 virus can linger in blood and tissue for more than a year after a person is first infected.

In their research on long COVID, the scientists found COVID antigens in the blood for up to 14 months after infection, and in tissue samples for more than 2 years after infection. 

“These two studies provide some of the strongest evidence so far that COVID antigens can persist in some people, even though we think they have normal immune responses,” Michael Peluso, MD, an infectious disease researcher in the UCSF School of Medicine, who led both studies, said in a statement. 

Scientists don’t know what causes long COVID, in which symptoms of the illness persist months or years after recovery. The most common symptoms are extreme fatigue, shortness of breath, loss of smell, and muscle aches.

The UCSF research team examined blood samples from 171 infected people and found the COVID “spike” protein was still present up to 14 months after infection in some people. The antigens were found more often in people who were hospitalized with COVID or who reported being very sick but were not hospitalized.

Researchers next looked at the UCSF Long COVID Tissue Bank, which contains samples donated by patients with and without long COVID. 

They found portions of viral RNA in the tissue up to 2 years after people were infected, though there was no evidence of reinfection. Those viral fragments were found in connective tissue where immune cells are, suggesting that the fragments caused the immune system to attack, according to the researchers. 

The UCSF team is running clinical trials to find out if monoclonal antibodies or antiviral drugs can remove the virus. 

The findings were presented in Denver this week at the Conference on Retroviruses and Opportunistic Infections.

Letícia Soares was infected with COVID-19 in April 2020, in the final year of postdoctoral studies in disease ecology at a Canadian University. What started with piercing migraines and severe fatigue in 2020 soon spiraled into a myriad of long COVID symptoms: Gastrointestinal issues, sleep problems, joint and muscle pain, along with unexpected menstrual changes.

After an absence of menstrual bleeding and its usual signs, she later suffered from severe periods and symptoms that worsened her long COVID condition. “It just baffled me,” said Soares, now 39. “It was debilitating.”

Cases like Soares’s are leading scientists to spend more time trying to understand the biological sex disparity in chronic illnesses such as long COVID that until recently have all but been ignored. According to the Centers for Disease Control and Prevention, long COVID affects nearly twice as many women as men.

What’s more, up to two thirds of female patients with long COVID report an increase in symptoms related to menstruation, which suggests a possible link between sex hormone fluctuations and immune dysfunction in the illness.

“These illnesses are underfunded and understudied relative to their disease burdens,” said Beth Pollack, a research scientist at the Massachusetts Institute of Technology, Cambridge, Massachusetts, who studies complex chronic illnesses.

Addressing knowledge gaps, especially around sex differences, could significantly improve our understanding of complex chronic illnesses, said Pollack, who coauthored a 2023 literature review of female reproductive health impacts of long COVID.

Emerging ‘Menstrual Science’ Could Be Key

There is a critical need, she said, for studies on these illnesses to include considerations of sex differences, hormones, reproductive phases, and reproductive conditions. This research could potentially inform doctors and other clinicians or lead to treatments, both for reproductive symptoms and for the illnesses themselves.

Pollack noted that reproductive symptoms are prevalent across a group of infection-associated chronic illnesses she studies, all of which disproportionately affect women. These associated conditions, traditionally studied in isolation, share pathologies like reproductive health concerns, signaling a need for focused research on their shared mechanisms.

Recognizing this critical gap, “menstrual science” is emerging as a pivotal area of study, aiming to connect these dots through focused research on hormonal influences.

Researchers at the University of Melbourne, Melbourne, Australia, for example, are studying whether hormones play a role in causing or worsening the symptoms of long COVID. By comparing hormone levels in people with these conditions with those in healthy people and by tracking how symptoms change with hormone levels over time and across menstrual cycles, scientists hope to find patterns that could help diagnose these conditions more easily and lead to new treatments. They’re also examining how hormonal life phases such as puberty, pregnancy, or perimenopause and hormone treatments like birth control might affect these illnesses.

How Gender and Long COVID Intertwine

The pathologies of long COVID, affecting at least 65 million people worldwide, currently focus on four hypotheses: Persistent viral infection, reactivation of dormant viruses (such as common herpes viruses), inflammation-related damage to tissues and organs, and autoimmunity (the body attacking itself).

It’s this last reason that holds some of the most interesting clues on biological sex differences, said Akiko Iwasaki, PhD, a Yale University, New Haven, Connecticut, immunologist who has led numerous research breakthroughs on long COVID since the start of the pandemic. Women have two X chromosomes, for example, and although one is inactivated, the inactivation is incomplete.

Some cells still express genes from the “inactivated genes” on the X chromosome, Iwasaki said. Those include key immune genes, which trigger a more robust response to infections and vaccinations but also predispose them to autoimmune reactions. “It comes at the cost of triggering too much immune response,” Iwasaki said.

Sex hormones also factor in. Testosterone, which is higher in males, is immunosuppressive, so it can dampen immune responses, Iwasaki said. That may contribute to making males more likely to get severe acute infections of COVID-19 but have fewer long-term effects.

Estrogen, on the other hand, is known to enhance the immune response. It can increase the production of antibodies and the activation of T cells, which are critical for fighting off infections. This heightened immune response, however, might also contribute to the persistent inflammation observed in long COVID, where the immune system continues to react even after the acute infection has resolved.

Sex-Specific Symptoms and Marginalized Communities

Of the more than 200 symptoms long haulers experience, Iwasaki said, several are also sex-specific. A recent draft study by Iwasaki and another leading COVID researcher, David Putrino, PhD, at Mount Sinai Health System in New York City, shows hair loss as one of the most female-dominant symptoms and sexual dysfunction among males.

In examining sex differences, another question is why long COVID rates in the trans community are disproportionately high. One of the reasons Iwasaki’s lab is looking at testosterone closely is because anecdotal evidence from female-to-male trans individuals indicates that testosterone therapy improved their long COVID symptoms significantly. It also raises the possibility that hormone therapy could help.

However, patients and advocates say it’s also important to consider socioeconomic factors in the trans community. “We need to start at this population and social structure level to understand why trans people over and over are put in harm’s way,” said JD Davids, a trans patient-researcher with long COVID and the cofounder and codirector of Strategies for High Impact and its Long COVID Justice project.

For trans people, said Davids, risk factors for both severe COVID and long COVID include being part of low-income groups, belonging to marginalized racial and ethnic communities, and living in crowded environments such as shelters or prisons.

The disproportionate impact of long COVID on marginalized communities, especially when seen through the lens of historical medical neglect, also demands attention, said Iwasaki. “Women used to be labeled hysteric when they complained about these kinds of symptoms.”

Where It All Leads

The possibility of diagnosing long COVID with a simple blood test could radically change some doctors’ false perceptions that it is not a real condition, Iwasaki said, ensuring it is recognized and treated with the seriousness it deserves.

“I feel like we need to get there with long COVID. If we can order a blood test and say somebody has a long COVID because of these values, then suddenly the diseases become medically explainable,” Iwasaki added. This advancement is critical for propelling research forward, she said, refining treatment approaches — including those that target sex-specific hormone, immunity, and inflammation issues — and improving the well-being of those living with long COVID.

This hope resonates with scientists like Pollack, who recently led the first National Institutes of Health-sponsored research webinar on less studied pathologies in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID, and with the experiences of individuals like Soares, who navigates through the unpredictable nature of both of these conditions with resilience.

“This illness never ceases to surprise me in how it changes my body. I feel like it’s a constant adaptation,” said Soares. Now living in Salvador, Brazil, her daily life has dramatically shifted to the confines of her home.

“It’s how I have more predictability in my symptoms,” she said, pointing out the pressing need for the scientific advancements that Iwasaki envisions and a deepening of our understanding of the disease’s impacts on patients’ lives.

TOPLINE:

A diet with a low glycemic index (GI) had protective effects against diabetes and other chronic diseases similar to those of a diet high in fiber and whole grains.

METHODOLOGY:

• A 2019 Lancet report from the World Health Organization promoted fiber and whole grains to manage type 2 diabetes, cardiovascular disease, and cancer but rejected GI as a relevant dietary factor to prevent chronic diseases.
• This meta-analysis assessed the evidence of how GI and glycemic load are associated with four main outcomes and did the same for diets high in fiber and whole grain.
• Researchers identified 10 large prospective cohort studies (each including ≥ 100,000 participants) that assessed associations of GI, glycemic load, and fiber and whole grains with the outcomes of interest.
• The mean age was 56 years, and the mean follow-up duration was 12.6 years.
• The primary outcomes were incidence of type 2 diabetes, cardiovascular diseases and its components, diabetes-related cancers, and all-cause mortality.

TAKEAWAY:

• Compared with low-GI diets, high-GI diets were associated with an increased risk for:
• Type 2 diabetes (relative risk [RR], 1.27; P < .0001)
• Total cardiovascular disease (RR, 1.15; P < .0001)
• Diabetes-related cancers (RR, 1.05; P = .0001)
• All-cause mortality (RR, 1.08; P < .0001), statistically significant in women only.
• Foods with high glycemic load were associated with an increased risk for incident type 2 diabetes (RR, 1.15; P < .0001) and total cardiovascular disease (RR, 1.15; P < .0001) than foods with a low glycemic load.
• A diet high in fiber and whole grains reduced the risk for all four outcomes, with the association being similar to that observed for low-GI diet.

IN PRACTICE:

“These findings justify the combination of GI with fiber and whole grains in dietary recommendations to reduce the risk of diabetes and related chronic diseases,” the authors wrote.

SOURCE:

This study was led by David J.A. Jenkins, MD, Department of Nutritional Sciences, Temerty Faculty of Medicine, University of Toronto, Ontario, Canada, and published online in The Lancet Diabetes & Endocrinology.

LIMITATIONS:

The lack of evaluation or absence of positive effects in some analyses may have led to a paucity of reported studies for some outcomes. Moreover, the findings for some outcomes may have had limited robustness because of a small difference in RR. Furthermore, only one or two cohorts were included to compare most disease outcomes related to GI with fiber and wholegrain exposure.

DISCLOSURES:

This study was funded by Banting and Best and the Karuna Foundation. The authors declared receiving research grants, payments, honoraria, and travel support from and having other ties with food and beverage growers, processors and manufacturers, as well as with foundations, chronic disease advocacy and research groups, professional societies, government organizations, and other sources.

TOPLINE:

A diet with a low glycemic index (GI) had protective effects against diabetes and other chronic diseases similar to those of a diet high in fiber and whole grains.

METHODOLOGY:

• A 2019 Lancet report from the World Health Organization promoted fiber and whole grains to manage type 2 diabetes, cardiovascular disease, and cancer but rejected GI as a relevant dietary factor to prevent chronic diseases.
• This meta-analysis assessed the evidence of how GI and glycemic load are associated with four main outcomes and did the same for diets high in fiber and whole grain.
• Researchers identified 10 large prospective cohort studies (each including ≥ 100,000 participants) that assessed associations of GI, glycemic load, and fiber and whole grains with the outcomes of interest.
• The mean age was 56 years, and the mean follow-up duration was 12.6 years.

Swiss scientists have identified immune system abnormalities in patients with long COVID that might open the door to new diagnostic tests and treatments.

The researchers found that a group of proteins in the blood that are part of the body’s immune response called the “complement system” are not working properly in patients with long COVID.

Blood samples turned up important differences between those who recovered from COVID and those who did not. These differences might be used as biomarkers to diagnose long COVID and might even point the way to new treatments for the condition, the researchers said.

By testing for 6500 blood proteins in about 300 patients, the Swiss researchers found that dysfunctional complement system proteins could possibly explain fatigue and “smoldering inflammation,” said Onur Boyman, MD, a professor of immunology from University Hospital Zurich in Zurich, Switzerland.

Long COVID has been linked to hundreds of symptoms including brain fog, chronic fatigue, pain, and digestive issues. Various factors drive the condition and likely work with one another other, said David Putrino, PhD, from the Icahn School of Medicine at Mount Sinai in New York City. The Swiss study is useful because “we’re trying to best understand how we can explain all of this far-reaching pathobiology,” he said.
 

Testing Across Continents

Dr. Boyman’s team collected blood samples from people with COVID in Europe and New York and tracked them. They compared those who developed long COVID with those who did not. One protein that was most unique to patients with long COVID is a blood complement that activates the immune system, Dr. Boyman said. But in people with long COVID, the immune response stays activated after the virus is gone. He described the response as “smoldering inflammation” in multiple organs, including the lungs and the gastrointestinal system.

The complement system also plays a role in clearing the body of dead cells. If the cells “lie around too much,” they can trigger an immune response, he said.

That may explain exercise intolerance in people with long COVID, Dr. Boyman said. Some people with long COVID have inflammation in the epithelium — the inner layer of their blood vessels. This would make it harder for the circulatory systems to recover from exercise, Dr. Boyman said.

“We think this regulated complement system is actually quite a central piece of the puzzle,” he said.
 

The Microclot Connection

The findings also support past research linking blood clots to long COVID. He suggested that clinicians and researchers consider testing drugs that regulate or inhibit the complementary system as a treatment of long COVID. Dr. Boyman said they are currently used for rare immune diseases.

Resia Pretorius, PhD, a professor of physiological sciences at Stellenbosch University in Stellenbosch, South Africa, said scientists studying the role of microclots in patients with long COVID often see complementary proteins inside the clots, so it has already been associated with long COVID. But she likened this clotting process to a garbage can that “just rolls along and collects everything that gets in its way. I think they are actively driving inflammation and disease.”

One factor complicating long COVID diagnosis and treatment is that it is a complex condition that involves multiple organ systems. That’s why the latest research suggests an underlying driver for the multiple symptoms of long COVID, Dr. Putrino said.

“Not every person has every symptom; not every person has every organ system affected,” Dr. Putrino said. “Whatever is happening is decided across the whole body.”
 

Research Offers New Direction

The Swiss paper contributes to the effort to identify systemic issues contributing to long COVID. It gives researchers one more thing to test for and link to specific, long COVID symptoms, opening the door to new treatments, Dr. Putrino said.

He doesn’t think the study supports treating the complement dysfunction if researchers don’t know what’s driving it. It may be complicated by the body’s failure to clear the virus completely, he said.

Dr. Pretorius recommended doctors test patients with long COVID for specific symptoms that may be treated using existing therapies. “If you think your patient had vascular pathology, you can test for it,” she said.

Some patients have found certain supplements and over-the-counter products helpful, she said. Among them: Coenzyme Q 10 and clot-busters such as streptokinase and Nattokinase (though she noted some doctors may not be comfortable with supplements).

“It’s the only thing we have until we’ve got trials,” she said.

Dr. Putrino said more research is needed to identify potential root causes and symptoms. A common refrain, but the only thing that will lead to specific treatments.

TOPLINE:

Gargling with mouthwash two to three times a day can reduce periodontopathic bacteria and possibly improve glycemic control in people with type 2 diabetes (T2D), especially younger adults.

METHODOLOGY:

• A total of 173 patients with T2D who had at least six total periodontopathic bacteria in their mouths and  ≥ 6.5% were instructed to gargle with water three times a day for 6 months, followed by gargling with chlorhexidine gluconate mouthwash three times a day for the next 6 months.
• Saliva specimens were collected every 1-2 months at clinic visits totaling 6-12 samples per study period and bacterial DNA examined for three red complex species, namely, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia.

TAKEAWAY:

• Twelve individuals who gargled once a day or less showed no significant reductions in red complex species after mouthwash or water gargling.
• By contrast, significant decreases in red complex bacteria were seen after 6 months of mouthwash gargling (P < .001) in the 80 who gargled twice a day and the 81 who did so three times a day compared with no changes after water gargling.
• Among the 161 individuals who gargled at least twice a day, the decrease in red species with mouthwash vs water gargling was highly significant (P < .0001).
• After adjustment for A1c seasonal variation, neither water gargling nor mouthwash gargling led to significant overall reduction in A1c levels.
• However, A1c levels were significantly lower in the 83 individuals aged ≤ 68 years than among the 78 aged ≥ 69 years after gargling with mouthwash (P < .05), with no change in either group after water gargling.
• Similarly, A1c levels were significantly reduced (P < .05) after mouthwash in the 69 with baseline A1c ≥ 7.5% compared with the 92 whose baseline A1c levels were ≤ 7.4%, with no changes in either after water.

IN PRACTICE:

“A bidirectional relationship between periodontitis and T2D has been reported. Patients with T2D are more susceptible to severe periodontitis than subjects without diabetes, and inflammatory periodontitis aggravates hyperglycemia, leading to inadequate glycemic control.” “Recently, it has been reported that patients with T2D treated for periodontitis have reduced periodontopathic bacteria and improved glycemic control. Patients with T2D complicated by periodontitis have more red complex species, and poor glycemic control is thought to be associated with increased levels of red complex species in the oral cavity.” “Further studies should be planned, taking into account various patient factors to determine the effect of mouthwash gargling on the amount of red complex species and A1c levels in patients with T2D.”

SOURCE:

This study was conducted by Saaya Matayoshi, of the Joint Research Laboratory of Science for Oral and Systemic Connection, Osaka University Graduate School of Dentistry, Osaka, Japan, and colleagues and published in Scientific Reports.

LIMITATIONS:

Only polymerase chain reaction used to detect periodontopathic bacteria so not quantified. No assessment of periodontal pocket depth. Saliva sampling conditions not standardized. Study conducted during COVID-19 pandemic; all patients wore masks. Heterogeneity in patient responses to the mouthwash.
