New Study Links Erythritol to Increased Stroke Risk

editorial

Published

on

Research from the University of Colorado Boulder indicates that erythritol, a widely used sugar substitute, may elevate the risk of stroke. The findings suggest that this popular sweetener, often found in low-carb products and sugar-free beverages, could negatively impact brain cells, leading to serious health concerns. The study was published in the Journal of Applied Physiology.

Erythritol, first approved by the Food and Drug Administration in 2001, is a sugar alcohol produced through the fermentation of corn. It contains minimal calories and is about 80% as sweet as table sugar, making it a preferred choice for individuals managing weight or blood sugar levels. Recent research, however, has raised alarms regarding its safety.

A significant study involving 4,000 people across the U.S. and Europe revealed that those with elevated erythritol levels in their bloodstream faced a higher likelihood of experiencing a heart attack or stroke within three years. To delve deeper into the mechanisms behind this correlation, Christopher DeSouza, a professor of integrative physiology, and graduate student Auburn Berry conducted laboratory experiments.

The researchers exposed human cells that line blood vessels in the brain to erythritol at concentrations comparable to those found in a standard sugar-free drink. The results highlighted several alarming changes: the cells produced significantly less nitric oxide, a vital molecule that relaxes blood vessels, while increasing levels of endothelin-1, a protein known to constrict blood vessels. Moreover, when exposed to thrombin, a compound that promotes clot formation, the cells showed a marked reduction in the production of t-PA, a natural clot-dissolving agent.

These findings suggest that if blood vessels are more constricted and the body’s ability to dissolve clots is compromised, the risk of stroke can increase significantly. Berry stated, “Our research demonstrates not only that, but how erythritol has the potential to increase stroke risk.”

While the study utilized a single serving of erythritol, DeSouza noted that individuals consuming multiple servings daily could face even greater risks. Although the research was conducted in a controlled laboratory setting and further studies on humans are necessary, DeSouza urges consumers to be vigilant.

He recommends reading product labels for erythritol or other “sugar alcohols.” “Given the epidemiological study that inspired our work, and now our cellular findings, we believe it would be prudent for people to monitor their consumption of non-nutritive sweeteners such as this one,” DeSouza emphasized.

As the conversation around dietary choices continues to evolve, these findings highlight the importance of understanding the potential health implications associated with popular food additives.

New Therapy Offers Hope for Cystic Fibrosis Patients in UK

editorial

Published

on

A new treatment for cystic fibrosis (CF) patients has received official approval in the United Kingdom, marking a significant advancement in the management of this challenging genetic condition. The National Institute for Health and Care Excellence (NICE) has approved the use of Alyftrek, a modulator therapy that targets the underlying cause of cystic fibrosis. This decision paves the way for hundreds of patients to access what health experts describe as a “life-changing” medication.

Alyftrek, also known as vanza triple, is designed for patients aged six and older who have the most common form of cystic fibrosis. It is expected to be an alternative to another treatment, Kaftrio, and has been developed to improve lung function and overall health outcomes for individuals living with CF.

Significant Approval for Rare Patient Populations

The approval of Alyftrek is particularly noteworthy as it also extends treatment options to patients with rare forms of cystic fibrosis who have not previously qualified for modulator therapies. According to NHS England, approximately 95 percent of cystic fibrosis patients in England will now be eligible for modulator therapy, a significant increase in access to vital treatments.

David Ramsden, chief executive of the Cystic Fibrosis Trust, expressed optimism about the announcement, stating, “Today’s announcements are another positive step in the journey to better treatments for everyone with cystic fibrosis – a lifelong, life-limiting condition without a cure.” This sentiment reflects the ongoing advocacy and efforts of the cystic fibrosis community, which has campaigned tirelessly for better treatment options.

Ludovic Fenaux, senior vice president at Vertex International, emphasized that this milestone represents a commitment to ongoing innovation aimed at enhancing the lives of individuals with cystic fibrosis.

Transformative Impact on Patients’ Lives

NHS officials have highlighted the potential of Alyftrek to significantly transform life expectancy and quality of life for patients. John Stewart, NHS England’s director for specialised commissioning, noted that the availability of a once-daily oral treatment can alleviate the burden of frequent hospital visits, allowing patients, especially children and young people, to live more freely.

Cystic fibrosis is a genetic disorder characterized by the accumulation of thick mucus in the lungs and digestive system, which leads to severe respiratory issues and chronic infections. The introduction of Alyftrek, alongside other modulator therapies, brings new hope to patients and families affected by this condition.

The Medicines and Healthcare products Regulatory Agency (MHRA) approved the triple combination medicine, which includes the active ingredients deutivacaftor, tezacaftor, and vanzacaftor, for use in the UK in March 2023. Clinical trials have shown that Alyftrek is as effective as Kaftrio in improving and maintaining lung function in individuals with cystic fibrosis.

As the NHS continues to embrace innovative treatments, the rollout of Alyftrek represents a significant advancement in cystic fibrosis care, providing patients with renewed hope for a better quality of life.

Men Turn to Ozempic After Study Links Drug to Higher Testosterone

editorial

Published

A recent study has revealed that medications like Ozempic, primarily used for managing blood sugar levels and promoting weight loss, may also boost testosterone levels in men. Researchers from SSM Health St. Louis University Hospital observed that men undergoing treatment with GLP-1 medications, which include semaglutide (Ozempic) and tirzepatide (Mounjaro), experienced a remarkable average increase of 24 percent in testosterone levels after 18 months of therapy.

Testosterone is crucial for male sexual development, muscle mass, bone density, and overall health. Low testosterone levels are frequently seen in men with obesity or Type 2 diabetes, contributing to fatigue, decreased libido, and a lowered quality of life. The findings from this study suggest that GLP-1 medications may not only help with weight management but could also positively influence reproductive health in affected individuals.

Significant Findings on Hormone Levels

The study involved an analysis of medical records from 110 adult men diagnosed with obesity or Type 2 diabetes. All participants were treated with semaglutide (Ozempic or Wegovy), dulaglutide (Trulicity), or tirzepatide (Zepbound) for an average of 18 months. Notably, none of the men were receiving testosterone or any hormonal therapy during this period. The results indicated an average weight loss of 10 percent, alongside a significant rise in testosterone levels from 53 percent to 77 percent.

Dr. Shellsea Portillo Canales, the lead author of the study and an endocrinology fellow at SSM Health St. Louis University Hospital, emphasized that while weight loss from lifestyle changes or bariatric surgery is known to increase testosterone levels, the impact of anti-obesity medications on hormone levels has not been extensively studied. She stated, “Our study is among the first to provide compelling evidence that low testosterone can be reversed with the use of commonly prescribed anti-obesity medications.”

Implications for Men’s Health

The correlation between weight loss and increased testosterone can be attributed to the reduction of body fat, which often leads to improved insulin sensitivity and lower overall inflammation. Both of these factors are essential for enhancing testosterone production and preventing its conversion into estrogen, which is a female hormone.

Despite the promising results, the authors of the study noted that further research is necessary to establish a definitive link between GLP-1 medications and increased testosterone levels. Dr. Fatima Cody Stanford, an obesity medicine physician scientist at Massachusetts General Hospital, commented on the study’s implications, highlighting the intersection between metabolic health and hormonal balance. She remarked, “This dual benefit underscores the potential of these medications to enhance overall health outcomes, including reproductive health, in this population.”

Average testosterone levels in men typically range from 300 to 1,000 nanograms per deciliter, and they tend to decline gradually with age. By the age of 75, the average male testosterone level is approximately 65 percent of that seen in younger adults, according to Dr. Portillo Canales.

These findings were presented at the ENDO 2025 conference, organized by the Endocrine Society in San Francisco. As interest in the multifaceted benefits of GLP-1 medications grows, it is clear that they may play a significant role in addressing both obesity and hormonal health in men.
