For Richer, for Poorer: Low-Carb Diets Work for All Incomes
For 3 years, Ajala Efem’s type 2 diabetes was so poorly controlled that her blood sugar often soared northward of 500 mg/dL despite insulin shots three to five times a day. She would experience dizziness, vomiting, severe headaches, and the neuropathy in her feet made walking painful. She was also — literally — frothing at the mouth. The 47-year-old single mother of two adult children with mental disabilities feared that she would die.
Ms. Efem lives in the South Bronx, which is among the poorest areas of New York City, where the combined rate of prediabetes and diabetes is close to 30%, the highest rate of any borough in the city.
She had to wait 8 months for an appointment with an endocrinologist, but that visit proved to be life-changing. She lost 28 pounds and got off 15 medications in a single month. She did not join a gym or count calories; she simply changed the food she ate and adopted a low-carb diet.
“I went from being sick to feeling so great,” she told her endocrinologist recently: “My feet aren’t hurting; I’m not in pain; I’m eating as much as I want, and I really enjoy my food so much.”
Ms. Efem’s life-changing visit was with Mariela Glandt, MD, at the offices of Essen Health Care. One month earlier, Dr. Glandt’s company, OwnaHealth, was contracted by Essen to conduct a 100-person pilot program for endocrinology patients. Essen is the largest Medicaid provider in New York City, and “they were desperate for an endocrinologist,” said Dr. Glandt, who trained at Columbia University in New York. So she came — all the way from Madrid, Spain. She commutes monthly, staying for a week each visit.
Dr. Glandt keeps up this punishing schedule because, as she explains, “it’s such a high for me to see these incredible transformations.” Her mostly Black and Hispanic patients are poor and lack resources, yet they lose significant amounts of weight, and their health issues resolve.
“Food is medicine” is an idea very much in vogue. The concept was central to the landmark White House Conference on Hunger, Nutrition, and Health in 2022 and is now the focus of a number of a wide range of government programs. Recently, the Senate held a hearing aimed at further expanding food as medicine programs.
Still, only a single randomized controlled clinical trial has been conducted on this nutritional approach, with unexpectedly disappointing results. In the mid-Atlantic region, 456 food-insecure adults with type 2 diabetes were randomly assigned to usual care or the provision of weekly groceries for their entire families for about 1 year. Provisions for a Mediterranean-style diet included whole grains, fruits and vegetables, lean protein, low-fat dairy products, cereal, brown rice, and bread. In addition, participants received dietary consultations. Yet, those who got free food and coaching did not see improvements in their average blood sugar (the study’s primary outcome), and their low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol levels appeared to have worsened.
“To be honest, I was surprised,” the study’s lead author, Joseph Doyle, PhD, professor at the Sloan School of Management at MIT in Cambridge, Massachusetts, told me. “I was hoping we would show improved outcomes, but the way to make progress is to do well-randomized trials to find out what works.”
I was not surprised by these results because a recent rigorous systematic review and meta-analysis in The BMJ did not show a Mediterranean-style diet to be the most effective for glycemic control. And Ms. Efem was not in fact following a Mediterranean-style diet.
Ms. Efem’s low-carb success story is anecdotal, but Dr. Glandt has an established track record from her 9 years’ experience as the medical director of the eponymous diabetes center she founded in Tel Aviv. A recent audit of 344 patients from the center found that after 6 months of following a very low–carbohydrate diet, 96.3% of those with diabetes saw their A1c fall from a median 7.6% to 6.3%. Weight loss was significant, with a median drop of 6.5 kg (14 pounds) for patients with diabetes and 5.7 kg for those with prediabetes. The diet comprises 5%-10% of calories from carbs, but Dr. Glandt does not use numeric targets with her patients.
Blood pressure, triglycerides, and liver enzymes also improved. And though LDL cholesterol went up by 8%, this result may have been offset by an accompanying 13% rise in HDL cholesterol. Of the 78 patients initially on insulin, 62 were able to stop this medication entirely.
Although these results aren’t from a clinical trial, they’re still highly meaningful because the current dietary standard of care for type 2 diabetes can only slow the progression of the disease, not cause remission. Indeed, the idea that type 2 diabetes could be put into remission was not seriously considered by the American Diabetes Association (ADA) until 2009. By 2019, an ADA report concluded that “[r]educing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia.” In other words, the best way to improve the key factor in diabetes is to reduce total carbohydrates. Yet, the ADA still advocates filling one quarter of one’s plate with carbohydrate-based foods, an amount that will prevent remission. Given that the ADA’s vision statement is “a life free of diabetes,” it seems negligent not to tell people with a deadly condition that they can reverse this diagnosis.
A 2023 meta-analysis of 42 controlled clinical trials on 4809 patients showed that a very low–carbohydrate ketogenic diet (keto) was “superior” to alternatives for glycemic control. A more recent review of 11 clinical trials found that this diet was equal but not superior to other nutritional approaches in terms of blood sugar control, but this review also concluded that keto led to greater increases in HDL cholesterol and lower triglycerides.
Dr. Glandt’s patients in the Bronx might not seem like obvious low-carb candidates. The diet is considered expensive and difficult to sustain. My interviews with a half dozen patients revealed some of these difficulties, but even for a woman living in a homeless shelter, the obstacles are not insurmountable.
Jerrilyn, who preferred that I use only her first name, lives in a shelter in Queens. While we strolled through a nearby park, she told me about her desire to lose weight and recover from polycystic ovary syndrome, which terrified her because it had caused dramatic hair loss. When she landed in Dr. Glandt’s office at age 28, she weighed 180 pounds.
Less than 5 months later, Jerrilyn had lost 25 pounds, and her period had returned with some regularity. She said she used “food stamps,” known as the Supplemental Nutrition Assistance Program (SNAP), to buy most of her food at local delis because the meals served at the shelter were too heavy in starches. She starts her day with eggs, turkey bacon, and avocado.
“It was hard to give up carbohydrates because in my culture [Latina], we have nothing but carbs: rice, potatoes, yuca,” Jerrilyn shared. She noticed that carbs make her hungrier, but after 3 days of going low-carb, her cravings diminished. “It was like getting over an addiction,” she said.
Jerrilyn told me she’d seen many doctors but none as involved as Dr. Glandt. “It feels awesome to know that I have a lot of really useful information coming from her all the time.” The OwnaHealth app tracks weight, blood pressure, blood sugar, ketones, meals, mood, and cravings. Patients wear continuous glucose monitors and enter other information manually. Ketone bodies are used to measure dietary adherence and are obtained through finger pricks and test strips provided by OwnaHealth. Dr. Glandt gives patients her own food plan, along with free visual guides to low-carbohydrate foods by dietdoctor.com.
Dr. Glandt also sends her patients for regular blood work. She says she does not frequently see a rise in LDL cholesterol, which can sometimes occur on a low-carbohydrate diet. This effect is most common among people who are lean and fit. She says she doesn’t discontinue statins unless cholesterol levels improve significantly.
Samuel Gonzalez, age 56, weighed 275 pounds when he walked into Dr. Glandt’s office this past November. His A1c was 9.2%, but none of his previous doctors had diagnosed him with diabetes. “I was like a walking bag of sugar!” he joked.
A low-carbohydrate diet seemed absurd to a Puerto Rican like himself: “Having coffee without sugar? That’s like sacrilegious in my culture!” exclaimed Mr. Gonzalez. Still, he managed, with SNAP, to cook eggs and bacon for breakfast and some kind of protein for dinner. He keeps lunch light, “like tuna fish,” and finds checking in with the OwnaHealth app to be very helpful. “Every day, I’m on it,” he said. In the past 7 months, he’s lost 50 pounds, normalized his cholesterol and blood pressure levels, and lowered his A1c to 5.5%.
Mr. Gonzalez gets disability payments due to a back injury, and Ms. Efem receives government payments because her husband died serving in the military. Ms. Efem says her new diet challenges her budget, but Mr. Gonzalez says he manages easily.
Mélissa Cruz, a 28-year-old studying to be a nail technician while also doing back office work at a physical therapy practice, says she’s stretched thin. “I end up sad because I can’t put energy into looking up recipes and cooking for me and my boyfriend,” she told me. She’ll often cook rice and plantains for him and meat for herself, but “it’s frustrating when I’m low on funds and can’t figure out what to eat.”
Low-carbohydrate diets have a reputation for being expensive because people often start eating pricier foods, like meat and cheese, to replace cheaper starchy foods such as pasta and rice.
A 2019 cost analysis published in Nutrition & Dietetics compared a low-carbohydrate dietary pattern with the New Zealand government’s recommended guidelines (which are almost identical to those in the United States) and found that it cost only an extra $1.27 in US dollars per person per day. One explanation is that protein and fat are more satiating than carbohydrates, so people who mostly consume these macronutrients often cut back on snacks like packaged chips, crackers, and even fruits. Also, those on a ketogenic diet usually cut down on medications, so the additional $1.27 daily is likely offset by reduced spending at the pharmacy.
It’s not just Bronx residents with low socioeconomic status (SES) who adapt well to low-carbohydrate diets. Among Alabama state employees with diabetes enrolled in a low-carbohydrate dietary program provided by a company called Virta, the low SES population had the best outcomes. Virta also published survey data in 2023 showing that participants in a program with the Veteran’s Administration did not find additional costs to be an obstacle to dietary adherence. In fact, some participants saw cost reductions due to decreased spending on processed snacks and fast foods.
Ms. Cruz told me she struggles financially, yet she’s still lost nearly 30 pounds in 5 months, and her A1c went from 7.1% down to 5.9%, putting her diabetes into remission. Equally motivating for her are the improvements she’s seen in other hormonal issues. Since childhood, she’s had acanthosis, a condition that causes the skin to darken in velvety patches, and more recently, she developed severe hirsutism to the point of growing sideburns. “I had tried going vegan and fasting, but these just weren’t sustainable for me, and I was so overwhelmed with counting calories all the time.” Now, on a low-carbohydrate diet, which doesn’t require calorie counting, she’s finally seeing both these conditions improve significantly.
When I last checked in with Ms. Cruz, she said she had “kind of ghosted” Dr. Glandt due to her work and school constraints, but she hadn’t abandoned the diet. She appreciated, too, that Dr. Glandt had not given up on her and kept calling and messaging. “She’s not at all like a typical doctor who would just tell me to lose weight and shake their head at me,” Ms. Cruz said.
Because Dr. Glandt’s approach is time-intensive and high-touch, it might seem impractical to scale up, but Dr. Glandt’s app uses artificial intelligence to help with communications thus allowing her, with help from part-time health coaches, to care for patients.
This early success in one of the United States’ poorest and sickest neighborhoods should give us hope that type 2 diabetes need not to be a progressive irreversible disease, even among the disadvantaged.
OwnaHealth’s track record, along with that of Virta and other similar low-carbohydrate medical practices also give hope to the food-is-medicine idea. Diabetes can go into remission, and people can be healed, provided that health practitioners prescribe the right foods. And in truth, it’s not a diet. It’s a way of eating that must be maintained. The sustainability of low-carbohydrate diets has been a point of contention, but the Virta trial, with 38% of patients sustaining remission at 2 years, showed that it’s possible. (OwnaHealth, for its part, offers long-term maintenance plans to help patients stay very low-carb permanently.)
Given the tremendous costs and health burden of diabetes, this approach should no doubt be the first line of treatment for doctors and the ADA. The past two decades of clinical trial research have demonstrated that remission of type 2 diabetes is possible through diet alone. It turns out that for metabolic diseases, only certain foods are truly medicine.

While we strolled through a nearby park, she told me about her desire to lose weight and recover from polycystic ovary syndrome, which terrified her because it had caused dramatic hair loss. When she landed in Dr. Glandt’s office at age 28, she weighed 180 pounds.
Less than 5 months later, Jerrilyn had lost 25 pounds, and her period had returned with some regularity. She said she used “food stamps,” known as the Supplemental Nutrition Assistance Program (SNAP), to buy most of her food at local delis because the meals served at the shelter were too heavy in starches. She starts her day with eggs, turkey bacon, and avocado.
“It was hard to give up carbohydrates because in my culture [Latina], we have nothing but carbs: rice, potatoes, yuca,” Jerrilyn shared. She noticed that carbs make her hungrier, but after 3 days of going low-carb, her cravings diminished. “It was like getting over an addiction,” she said.
Jerrilyn told me she’d seen many doctors but none as involved as Dr. Glandt. “It feels awesome to know that I have a lot of really useful information coming from her all the time.” The OwnaHealth app tracks weight, blood pressure, blood sugar, ketones, meals, mood, and cravings. Patients wear continuous glucose monitors and enter other information manually. Ketone bodies are used to measure dietary adherence and are obtained through finger pricks and test strips provided by OwnaHealth. Dr. Glandt gives patients her own food plan, along with free visual guides to low-carbohydrate foods by dietdoctor.com.
Dr. Glandt also sends her patients for regular blood work. She says she does not frequently see a rise in LDL cholesterol, which can sometimes occur on a low-carbohydrate diet. This effect is most common among people who are lean and fit. She says she doesn’t discontinue statins unless cholesterol levels improve significantly.
Samuel Gonzalez, age 56, weighed 275 pounds when he walked into Dr. Glandt’s office this past November. His A1c was 9.2%, but none of his previous doctors had diagnosed him with diabetes. “I was like a walking bag of sugar!” he joked.
A low-carbohydrate diet seemed absurd to a Puerto Rican like himself: “Having coffee without sugar? That’s like sacrilegious in my culture!” exclaimed Mr. Gonzalez. Still, he managed, with SNAP, to cook eggs and bacon for breakfast and some kind of protein for dinner. He keeps lunch light, “like tuna fish,” and finds checking in with the OwnaHealth app to be very helpful. “Every day, I’m on it,” he said. In the past 7 months, he’s lost 50 pounds, normalized his cholesterol and blood pressure levels, and lowered his A1c to 5.5%.
Mr. Gonzalez gets disability payments due to a back injury, and Ms. Efem receives government payments because her husband died serving in the military. Ms. Efem says her new diet challenges her budget, but Mr. Gonzalez says he manages easily.
Mélissa Cruz, a 28-year-old studying to be a nail technician while also doing back office work at a physical therapy practice, says she’s stretched thin. “I end up sad because I can’t put energy into looking up recipes and cooking for me and my boyfriend,” she told me. She’ll often cook rice and plantains for him and meat for herself, but “it’s frustrating when I’m low on funds and can’t figure out what to eat.”
Low-carbohydrate diets have a reputation for being expensive because people often start eating pricier foods, like meat and cheese, to replace cheaper starchy foods such as pasta and rice.
A 2019 cost analysis published in Nutrition & Dietetics compared a low-carbohydrate dietary pattern with the New Zealand government’s recommended guidelines (which are almost identical to those in the United States) and found that it cost only an extra $1.27 in US dollars per person per day. One explanation is that protein and fat are more satiating than carbohydrates, so people who mostly consume these macronutrients often cut back on snacks like packaged chips, crackers, and even fruits. Also, those on a ketogenic diet usually cut down on medications, so the additional $1.27 daily is likely offset by reduced spending at the pharmacy.
It’s not just Bronx residents with low socioeconomic status (SES) who adapt well to low-carbohydrate diets. Among Alabama state employees with diabetes enrolled in a low-carbohydrate dietary program provided by a company called Virta, the low SES population had the best outcomes. Virta also published survey data in 2023 showing that participants in a program with the Veteran’s Administration did not find additional costs to be an obstacle to dietary adherence. In fact, some participants saw cost reductions due to decreased spending on processed snacks and fast foods.
Ms. Cruz told me she struggles financially, yet she’s still lost nearly 30 pounds in 5 months, and her A1c went from 7.1% down to 5.9%, putting her diabetes into remission. Equally motivating for her are the improvements she’s seen in other hormonal issues. Since childhood, she’s had acanthosis, a condition that causes the skin to darken in velvety patches, and more recently, she developed severe hirsutism to the point of growing sideburns. “I had tried going vegan and fasting, but these just weren’t sustainable for me, and I was so overwhelmed with counting calories all the time.” Now, on a low-carbohydrate diet, which doesn’t require calorie counting, she’s finally seeing both these conditions improve significantly.
When I last checked in with Ms. Cruz, she said she had “kind of ghosted” Dr. Glandt due to her work and school constraints, but she hadn’t abandoned the diet. She appreciated, too, that Dr. Glandt had not given up on her and kept calling and messaging. “She’s not at all like a typical doctor who would just tell me to lose weight and shake their head at me,” Ms. Cruz said.
Because Dr. Glandt’s approach is time-intensive and high-touch, it might seem impractical to scale up, but Dr. Glandt’s app uses artificial intelligence to help with communications thus allowing her, with help from part-time health coaches, to care for patients.
This early success in one of the United States’ poorest and sickest neighborhoods should give us hope that type 2 diabetes need not to be a progressive irreversible disease, even among the disadvantaged.
OwnaHealth’s track record, along with that of Virta and other similar low-carbohydrate medical practices also give hope to the food-is-medicine idea. Diabetes can go into remission, and people can be healed, provided that health practitioners prescribe the right foods. And in truth, it’s not a diet. It’s a way of eating that must be maintained. The sustainability of low-carbohydrate diets has been a point of contention, but the Virta trial, with 38% of patients sustaining remission at 2 years, showed that it’s possible. (OwnaHealth, for its part, offers long-term maintenance plans to help patients stay very low-carb permanently.)
Given the tremendous costs and health burden of diabetes, this approach should no doubt be the first line of treatment for doctors and the ADA. The past two decades of clinical trial research have demonstrated that remission of type 2 diabetes is possible through diet alone. It turns out that for metabolic diseases, only certain foods are truly medicine.

Does An Elevated Lp(a) Call for Low-dose Aspirin?
Should a patient with high lipoprotein (a), or Lp(a), be started on low-dose aspirin?
This is the conundrum facing many physicians and patients, but even getting to that point will require more availability and coverage of tests and a greater appreciation of the risk associated with Lp(a), said cardiologists.
Lp(a): The Silent Risk
On Lp(a) Awareness Day, C. Michael Gibson, MD, MA, CEO of the Baim Institute for Clinical Research, Boston, Massachusetts, and PERFUSE took the opportunity to talk about his experiences with testing on X.
The professor of medicine at Harvard Medical School, also in Boston, said he was surprised to find that he had a very high calcium score, despite a low-density lipoprotein (LDL) cholesterol level of just 70 mg/dL. Eventually, he found out that he had a “very, very high Lp(a),” which was particularly concerning because his grandfather died of a heart attack at 45 years of age.
But how much risk does that represent?
A 2022 consensus statement from the European Atherosclerosis Society (EAS) highlighted that epidemiologic and genetic studies “strongly support a causal and continuous association between Lp(a) concentration and cardiovascular outcomes,” even at very low LDL cholesterol levels.
This is because Lp(a) has proinflammatory and proatherosclerotic properties, and high levels are associated with both micro- and macrocalcification of the aortic valve. Findings from a US registry study also suggest the threshold related to increased cardiovascular risk may differ for primary and secondary prevention populations (J Am Coll Cardiol. 2024 Mar 5;83[9]:873-886).
Lp(a) is, however, genetically determined, and there are no drugs available that directly lower levels, although some are on the horizon. In the meantime, the experts behind the consensus statement recommend that all adults be tested at least once in their lifetime.
Testing Cost and Availability
This recommendation has been translated into guidelines in “many, many” countries, said lead author Florian Kronenberg, MD, MAE, Institute of Genetic Epidemiology, Medical University of Innsbruck, Innsbruck, Austria, but “we are far away from reaching that goal.”
“We’ve got a real problem,” added Stephen Nicholls, MD, PhD, director of the Victorian Heart Institute and a professor of cardiology at Monash University, Melbourne, Australia, as there is “not a country in the world where there’s good access to Lp(a) testing.”
Dr. Kronenberg said that the consensus statement “created a kind of momentum” toward universal testing.
Ulrich Laufs, MD, PhD, professor and chair, Department of Cardiology, University Hospital Leipzig, Leipzig, Germany, agreed, saying that, overall, Lp(a) testing has “increased dramatically,” albeit from “extremely low levels.”
Dr. Kronenberg believes that “we have to be really patient.” He cited a lack of knowledge among physicians as one of the biggest barriers to greater uptake of testing.
“There is still no appreciation of the role of Lp(a),” agreed Alberico L. Catapano, MD, PhD, director of Cardiovascular Research and of the Lipoproteins and Atherosclerosis Laboratory of IRCCS Multimedica, Milan, Italy, and past president of the EAS.
“That’s why it’s not mentioned” to patients, he said. “What is really needed is to inform physician colleagues that Lp(a) is not only a risk factor but is the cause” of atherosclerotic cardiovascular disease (ASCVD).
Dr. Kronenberg said that the pressure for testing can often come from the patient themselves.
Physicians then question why the patient wants to be tested when there are no medications to treat it, he added. “We really tried very hard when we did the consensus paper to say that we should perform the test and give people advice on what to do.”
Dr. Catapano believes that another major obstacle is the cost of the test, which remains high “because very few people do it,” and there is some debate over which test to use.
Taken together, these issues have meant that “payers are really struggling with the idea of funding Lp(a),” said Dr. Nicholls, adding that “there seems to be this fixation on: ‘Well, if you can’t lower Lp(a), why measure it?’ ”
Rather than blame the payers, he says there is a need to educate about the science behind testing and underline that Lp(a) is an “important risk enhancer” for cardiovascular disease.
“Because if we’re going to make people pay out of pocket, then you’re creating a massive equity issue in that only those who can afford the test have it.”
High Lp(a) Now What?
But once the test has been performed, there then comes the question as to what to do about the result.
“Before we get anywhere near an agent that effectively lowers Lp(a) and get it into the clinic, there are lots of things that we can do today,” said Dr. Nicholls.
If someone has an intermediate or high background cardiovascular risk and they have got a high Lp(a) level, they “should be treated more intensively, as we know that high Lp(a) patients do better if their LDL cholesterol and their blood pressure is lower.”
For Dr. Catapano, this means having the “same mindset as you do with [a patient with] high blood pressure, high LDL cholesterol, and so on, because it’s exactly the same thing: It’s interacting with your other risk factors to increase your overall risk.”
Dr. Gibson agreed. Through a range of measures, including weight loss and statin therapy, he was able to reduce his overall cardiovascular risk, and his LDL cholesterol level dropped to just 20 mg/dL.
A Role for Aspirin?
It gained added momentum when Pablo Corral, MD, a lipidologist and a professor in the School of Medicine, Pharmacology Department, FASTA University, Mar del Plata, Buenos Aires, Argentina, highlighted the issue on X.
He pointed to a recent study, which showed that regular aspirin use was associated with a significantly lower rate of ASCVD mortality in adults without clinical ASCVD but who had elevated Lp(a).
Dr. Nicholls said that, when you “peel away the layers” of the current evidence, there is some suggestion that Lp(a)may be prothrombotic. “So in theory, perhaps aspirin might be maybe more intuitively useful there.”
He noted that the ASPREE primary prevention study found that low-dose aspirin in older adults resulted in a significantly higher risk for major hemorrhage over placebo and did not significantly reduce the risk for cardiovascular disease.
But an analysis he and his colleagues did suggest that aspirin may indeed benefit older individuals if they have elevated Lp(a) genotypes.
An Individual Decision
For Dr. Kronenberg and Dr. Laufs, there is currently a lack of appropriate data to make a recommendation either way, particularly for primary prevention.
They warned that the risk for thrombosis in patients with mildly elevated Lp(a) cannot be discounted, and in most cases either “the existing risk of bleeding exceeds the beneficial effects [of aspirin], or it’s not indicated,” said Dr. Laufs.
“When we make a recommendation, we should have evidence-based data,” Dr. Kronenberg said, but, at the moment, people “somehow put their finger in the air and see” which way the wind is blowing.
Dr. Catapano urged patients to talk to their physician, as even low-dose aspirin is “very potent” at inhibiting platelets.
Dr. Gibson agreed, saying that he is in two minds, as the potential benefit has to be weighed against the bleeding risk.
He personally takes low-dose aspirin because “I know I have a low bleeding risk,” but it is a decision “that has to be taken individually between a patient and their physician.”
Dr. Gibson, Dr. Kronenberg, Dr. Nicholls, and Dr. Catapano all reported conflicts of interest with numerous pharmaceutical companies and organizations.

Sex Hormones Linked to Fatty Liver in Men With T2D
TOPLINE:
In men with type 2 diabetes (T2D), higher serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were associated with a lower risk for metabolic dysfunction–associated fatty liver disease (MAFLD), whereas higher progesterone levels were associated with a higher risk. In women with T2D, sex- or thyroid-related hormones were not independently associated with the risk for MAFLD.
METHODOLOGY:
- People with T2D may have FLD, and this study explored the link between sex-related and thyroid-related hormone levels and MAFLD to explore and confirm risk factors.
- The researchers used a 2020 definition of MAFLD, now defined in patients as both hepatic steatosis and the presence of overweight/obesity, T2D, or evidence of metabolic dysfunction in lean individuals.
- This cross-sectional study conducted in one hospital in China included 432 patients hospitalized because of T2D and its complications from January 2018 to April 2020 (median T2D duration, 6 years; mean age, 55.8 years; 247 men and 185 postmenopausal women).
- Researchers measured and later adjusted for potential confounding factors, including weight, height, waist circumference, arterial blood pressure, glycemic parameters, liver function, and lipid profiles.
- They assessed blood levels of sex and thyroid hormones by chemiluminescent immunoassays; MAFLD was diagnosed by either ultrasonography findings of hepatic steatosis or a high liver fat index score (fatty liver index > 60).
TAKEAWAY:
- Overall, 275 (63.7%) patients were diagnosed with MAFLD; after adjusting for potential confounding factors, none of the sex- and thyroid-related hormones were independently associated with the risk for MAFLD in all patients with T2D.
- In men with T2D, higher serum levels of FSH (adjusted odds ratio [aOR], 0.919; P = .019) and LH (aOR, 0.888; P = .022) were associated with a reduced risk for MAFLD.
- Higher serum levels of progesterone were associated with an increased risk for MAFLD in men with T2D (aOR, 8.069; P = .003).
- In women with T2D, sex hormones and thyroid hormones were not significantly linked to the risk of developing MAFLD.
IN PRACTICE:
“Our findings could be used to imply that screening for MAFLD and monitoring sex-related hormones are important for T2D patients, especially in men,” the authors wrote.
SOURCE:
This study was led by Weihong Lu, Xiamen Clinical Research Center for Cancer Therapy, Xiamen, China; Shangjian Li, Zhongshan Hospital (Xiamen), Fudan University, Xiamen, China; and Yuhua Li, China University of Mining & Technology-Beijing, Beijing, and was published online in BMC Endocrine Disorders.
LIMITATIONS:
Temporal sequences of the associations between sex-related and thyroid-related hormones and MAFLD were not evaluated because of the cross-sectional nature of the study. The small sample size from a single institution may have introduced selection bias. Serum levels of sex hormone-binding globulin and free testosterone were not assessed. The postmenopausal status of women in the study may have affected the ability to find sex-hormone related associations. The findings can only be limitedly extrapolated to similar patients with T2D but not the general population.
DISCLOSURES:
The study was supported by the Fujian Province Nature Science Foundations, China, and the Guiding Project on Medicine and Health in Xiamen, China. The authors declared no conflicts of interest.

METHODOLOGY:
- People with T2D may have FLD, and this study explored the link between sex-related and thyroid-related hormone levels and MAFLD to explore and confirm risk factors.
- The researchers used a 2020 definition of MAFLD, now defined in patients as both hepatic steatosis and the presence of overweight/obesity, T2D, or evidence of metabolic dysfunction in lean individuals.
- This cross-sectional study conducted in one hospital in China included 432 patients hospitalized because of T2D and its complications from January 2018 to April 2020 (median T2D duration, 6 years; mean age, 55.8 years; 247 men and 185 postmenopausal women).
- Researchers measured and later adjusted for potential confounding factors, including weight, height, waist circumference, arterial blood pressure, glycemic parameters, liver function, and lipid profiles.
- They assessed blood levels of sex and thyroid hormones by chemiluminescent immunoassays; MAFLD was diagnosed by either ultrasonography findings of hepatic steatosis or a high liver fat index score (fatty liver index > 60).
TAKEAWAY:
- Overall, 275 (63.7%) patients were diagnosed with MAFLD; after adjusting for potential confounding factors, none of the sex- and thyroid-related hormones were independently associated with the risk for MAFLD in all patients with T2D.
- In men with T2D, higher serum levels of FSH (adjusted odds ratio [aOR], 0.919; P = .019) and LH (aOR, 0.888; P = .022) were associated with a reduced risk for MAFLD.
- Higher serum levels of progesterone were associated with an increased risk for MAFLD in men with T2D (aOR, 8.069; P = .003).
- In women with T2D, sex hormones and thyroid hormones were not significantly linked to the risk of developing MAFLD.
IN PRACTICE:
“Our findings could be used to imply that screening for MAFLD and monitoring sex-related hormones are important for T2D patients, especially in men,” the authors wrote.

Novel PCSK9 Drives High-Risk Patients to Target LDL
LYON, France – Lerodalcibep, a novel, third-generation anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, helps high-risk patients already receiving maximally tolerated statins to achieve guideline lipid targets, reported investigators.
In the randomized, placebo-controlled LIBerate-CVD trial of more than 900 patients, lerodalcibep led to reductions from baseline in low-density lipoprotein (LDL) cholesterol levels of more than 60%.
“We believe that lerodalcibep offers a novel, effective alternative to current PCSK9 inhibitors for patients with cardiovascular disease or at very high risk for cardiovascular disease,” said Evan Stein, MD, PhD, chief scientific officer and cofounder of LIB Therapeutics in Chicago, who presented the findings at the European Atherosclerosis Society (EAS) 2024.
Moreover, it leads to “substantial additional LDL cholesterol reductions on top of existing oral agents” and allows more than 90% of patients to achieve the latest European Society of Cardiology (ESC) guideline targets, he said.
Lerodalcibep has “tolerability and safety similar to placebo,” Dr. Stein said, and requires only “a small monthly injection, which takes about 12 seconds.”
“The drug doesn’t require refrigeration” and is “stable, so far, over 9 months,” he reported.
The latest data “confirm the efficacy of lerodalcibep,” said Giuseppe Danilo Norata, PhD, from the Department of Pharmacological and Biomolecular Sciences at the University of Milan, Milan, Italy, who was not involved in the study.
The LDL cholesterol reduction in this phase 3 trial is “in line with what was observed in LIBerate-FH,” and the high proportion of patients achieving their LDL cholesterol target is “impressive,” he added.
Effective and Well Tolerated
The safety results are “suggestive of a drug that is well tolerated, with injection-site reactions being the only remarkable adverse event increased in the treatment group,” Dr. Norata reported.
Only a “limited number” of patients developed neutralizing antidrug antibodies, which did not affect the efficacy of lerodalcibep. However, “given that the therapy is expected to be administered for years,” a longer analysis is needed to exclude the concern that a small percentage of neutralizing antidrug antibodies could reduce the efficacy, he said.
If approved, lerodalcibep could end up as a first-line option in the treatment pathway for high-risk cardiovascular disease because the efficacy “is similar to that of other injectable PCSK9 inhibitors,” he said, adding that its position in the market will “largely depend on the price.”
As the mechanism of action is similar to that of other monoclonal antibodies, “there is no pharmacological rationale to use it after another PSCK9 inhibitor,” he explained.
Lerodalcibep is a small recombinant fusion protein that combines a PCSK9-binding domain with human serum albumin.
The binding domain blocks the interaction between PCSK9 and the LDL cholesterol receptor, and the albumin linkage increases the half-life to 12-15 days, allowing low-volume injections to be given every 4 weeks.
A prior phase 2 study suggested that lerodalcibep substantially decreases LDL cholesterol levels in patients already taking maximally tolerated statins. The 300-mg dose was associated with an average reduction from baseline in LDL cholesterol levels of 77% over 12 weeks, whereas free PCSK9 levels decreased by 88%.
The current phase 3 study enrolled individuals at 65 centers in 100 countries who had or were at a very high risk for cardiovascular disease and who had an LDL cholesterol level of ≥ 1.8 mmol/L despite being on maximally tolerated statins.
Study participants were randomized in a 2:1 ratio to receive monthly subcutaneous lerodalcibep (n = 614) or placebo (n = 308) for 52 weeks and were assessed for the co-primary endpoints of the percentage change in LDL cholesterol levels from baseline to week 52 and the mean of levels at weeks 50 and 52.
The mean age was similar in the lerodalcibep and placebo groups (63.3 vs 64.5 years), as were the proportion of female (30% vs 30%) and White (80% vs 79%) participants.
The vast majority of participants in the lerodalcibep and placebo groups had a documented cardiovascular event (85.3% vs 86.4%) and were receiving secondary prevention, and 87% and 82%, respectively, were receiving a statin (any dose).
In a modified intention-to-treat analysis, the mean placebo-adjusted reduction in LDL cholesterol levels from baseline with lerodalcibep was 62% at week 52 (P < .0001), and the mean of levels at weeks 50 and 52 was 69.4% (P < .0001).
Similar results were seen in a per protocol analysis and an intention-to-treat analysis with imputation, which is a US Food and Drug Administration measure introduced in 2021 that assumes patients who discontinue the study treatment have an outcome similar to that in the placebo patients.
Moreover, 98.2% of patients in the lerodalcibep group achieved the ESC and European Atherosclerosis Society recommended reduction in LDL cholesterol levels of ≥ 50%, whereas only 8.8% in the placebo group did.
Hitting the LDL Cholesterol Target
More patients in the lerodalcibep group than in the placebo group achieved the LDL cholesterol target of < 1.4 mmol/L (95.3% vs 18.5%), and more patients in the lerodalcibep group achieved both that target and the ≥ 50% target (94.5% and 6.8%).
Lerodalcibep was also associated with significant reductions from baseline in levels of non–high-density lipoprotein (HDL) cholesterol, apolipoprotein B, very LDL cholesterol, and triglycerides, as well as an increase in HDL cholesterol levels (P < .0001 for all).
In terms of safety, lerodalcibep was associated with an adverse event rate leading to withdrawal similar to that seen with placebo (4.2% vs 3.6%), and 15.9% and 14.8% of patients, respectively, experienced at least one serious adverse event.
In-stent restenosis occurred more often in the lerodalcibep group than in the placebo group (5.4% vs 2.0%).
The study drug was associated with low levels of transient and sporadic antidrug antibodies and a low rate of neutralizing antidrug antibodies (0.9%), which were not associated with restenosis, a reduction in free PCSK9 levels, or the ability of lerodalcibep to lower LDL cholesterol levels.

FROM EAS 2024
Akira Endo, the Father of Statins, Dies
Akira Endo, PhD, the Japanese microbiologist and biochemist known as the father of statins, died at the age of 90 on June 5. His research led to the discovery and rise of a class of drugs that revolutionized the prevention and treatment of cardiovascular diseases. This scientific journey began over half a century ago.
Inspired by Alexander Fleming
Born into a family of farmers in northern Japan, Dr. Endo was fascinated by natural sciences from a young age and showed a particular interest in fungi and molds. At the age of 10, he already knew he wanted to become a scientist.
He studied in Japan and the United States, conducting research at the Albert Einstein College of Medicine in New York City. He was struck by the high number of elderly and overweight individuals in the United States and realized the importance of developing a drug to combat cholesterol. It was upon his return to Japan, when he joined the Sankyo laboratory, that the development of statins began.
Inspired by Alexander Fleming, who discovered penicillin in the mold Penicillium, he hypothesized that fungi could produce antibiotics inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the enzyme that produces cholesterol precursors.
After a year of research on nearly 3800 strains, his team found a known substance, citrinin, that strongly inhibited HMG-CoA reductase and lowered serum cholesterol levels in rats. The research was halted because of its toxicity to the rodents’ kidneys. “Nevertheless, the experience with citrinin gave us hope and courage to quickly discover much more effective active substances,” said Dr. Endo in an article dedicated to the discovery of statins.
First Statin Discovered
In the summer of 1972, researchers discovered a second active culture broth, Penicillium citrinum Pen-51, which was isolated from a sample of rice collected in a grain store in Kyoto.
In July 1973, they isolated three active metabolites from this mold, one of which was compactin, which had structural similarities to HMG-CoA, the substrate of the HMG-CoA reductase reaction.
In 1976, they published two articles reporting the discovery and characterization of compactin (mevastatin), the first statin.
Several Setbacks
Unfortunately, when Sankyo biologists assessed the effectiveness of compactin by giving rats a diet supplemented with compactin for 7 days, no reduction in serum cholesterol was observed.
Only later did an unpublished study show that the statin significantly decreased plasma cholesterol after a month of treatment in laying hens. The hypocholesterolemic effects of compactin were then demonstrated in dogs and monkeys.
However, researchers faced a second challenge in April 1977. Microcrystalline structures were detected in the liver cells of rats that had been fed extremely high amounts of compactin (over 500 mg/kg per day for 5 weeks). Initially deemed toxic, the structures were ultimately found to be nontoxic.
A phase 2 trial began in the summer of 1979 with very encouraging preliminary results, but in August 1980, clinical development of compactin was halted, as the drug was suspected of causing lymphomas in dogs given very high doses: 100 or 200 mg/kg per day for 2 years.
This suspicion also led to the termination of trials on another statin, the closely related lovastatin, which was discovered simultaneously from different fungi by the Merck laboratory and Dr. Endo in February 1979.
First Statin Marketed
It was confirmed that the drug significantly reduced cholesterol levels and was well tolerated. No tumors were detected.
Lovastatin received approval from the Food and Drug Administration to become the first marketed statin in September 1987.
Dr. Endo received numerous awards for his work, including the Albert Lasker Award for Clinical Medical Research in 2008 and the Outstanding Achievement Award from the International Atherosclerosis Society in 2009.

Akira Endo, PhD, the Japanese microbiologist and biochemist known as the father of statins, died at the age of 90 on June 5. His research led to the discovery and rise of a class of drugs that revolutionized the prevention and treatment of cardiovascular diseases. This scientific journey began over half a century ago.
Inspired by Alexander Fleming
Born into a family of farmers in northern Japan, Dr. Endo was fascinated by natural sciences from a young age and showed a particular interest in fungi and molds. At the age of 10, he already knew he wanted to become a scientist.
He studied in Japan and the United States, conducting research at the Albert Einstein College of Medicine in New York City. He was struck by the high number of elderly and overweight individuals in the United States and realized the importance of developing a drug to combat cholesterol. It was upon his return to Japan, when he joined the Sankyo laboratory, that the development of statins began.
Inspired by Alexander Fleming, who discovered penicillin in the mold Penicillium, he hypothesized that fungi could produce antibiotics inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the enzyme that produces cholesterol precursors.
After a year of research on nearly 3800 strains, his team found a known substance, citrinin, that strongly inhibited HMG-CoA reductase and lowered serum cholesterol levels in rats. The research was halted because of its toxicity to the rodents’ kidneys. “Nevertheless, the experience with citrinin gave us hope and courage to quickly discover much more effective active substances,” said Dr. Endo in an article dedicated to the discovery of statins.
First Statin Discovered
In the summer of 1972, researchers discovered a second active culture broth, Penicillium citrinum Pen-51, which was isolated from a sample of rice collected in a grain store in Kyoto.
In July 1973, they isolated three active metabolites from this mold, one of which was compactin, which had structural similarities to HMG-CoA, the substrate of the HMG-CoA reductase reaction.
In 1976, they published two articles reporting the discovery and characterization of compactin (mevastatin), the first statin.
Several Setbacks
Unfortunately, when Sankyo biologists assessed the effectiveness of compactin by giving rats a diet supplemented with compactin for 7 days, no reduction in serum cholesterol was observed.
Only later did an unpublished study show that the statin significantly decreased plasma cholesterol after a month of treatment in laying hens. The hypocholesterolemic effects of compactin were then demonstrated in dogs and monkeys.
However, researchers faced a second challenge in April 1977. Microcrystalline structures were detected in the liver cells of rats that had been fed extremely high amounts of compactin (over 500 mg/kg per day for 5 weeks). Initially deemed toxic, the structures were ultimately found to be nontoxic.
A phase 2 trial began in the summer of 1979 with very encouraging preliminary results, but in August 1980, clinical development of compactin was halted, as the drug was suspected of causing lymphomas in dogs given very high doses: 100 or 200 mg/kg per day for 2 years.
This suspicion also led to the termination of trials on another statin, the closely related lovastatin, which was discovered simultaneously from different fungi by the Merck laboratory and Dr. Endo in February 1979.
First Statin Marketed
It was confirmed that the drug significantly reduced cholesterol levels and was well tolerated. No tumors were detected.
Lovastatin received approval from the Food and Drug Administration to become the first marketed statin in September 1987.
Dr. Endo received numerous awards for his work, including the Albert Lasker Award for Clinical Medical Research in 2008 and the Outstanding Achievement Award from the International Atherosclerosis Society in 2009.

Study Finds Mace Risk Remains High in Patients with Psoriasis, Dyslipidemia
Over a period of 5 years, the, even after adjusting for covariates, results from a large retrospective study showed.
“It is well-established that psoriasis is an independent risk factor for the development of MACE, with cardiometabolic risk factors being more prevalent and incident among patients with psoriasis,” the study’s first author Ana Ormaza Vera, MD, a dermatology research fellow at Eastern Virginia Medical School, Norfolk, said in an interview after the annual meeting of the Society for Investigational Dermatology, where the study was presented during a late-breaking abstract session.
Current guidelines from the joint American Academy of Dermatology/National Psoriasis Foundation and the American Academy of Cardiology/American Heart Association Task Force recommend statins, a lipid-lowering and anti-inflammatory therapy, “for patients with psoriasis who have additional risk-enhancing factors, similar to recommendations made for the general population without psoriasis,” she noted. But how the incidence of MACE differs between patients with and without psoriasis while on statin therapy “has not been explored in real-world settings,” she added.
To address this question, the researchers used real-world data from the TriNetX health research network to identify individuals aged 18-90 years with a diagnosis of both psoriasis and lipid disorders who were undergoing treatment with statins. Those with a prior history of MACE were excluded from the analysis. Patients with lipid disorders on statin therapy, but without psoriatic disease, were matched 1:1 by age, sex, race, ethnicity, common risk factors for MACE, and medications shown to reduce MACE risk. The researchers then assessed the cohorts 5 years following their first statin prescription and used the TriNetX analytics tool to calculate the odds ratio (OR) with 95% CI to evaluate the likelihood of MACE in the presence of statin therapy.
Dr. Ormaza Vera and colleagues identified 20,660 patients with psoriasis and 2,768,429 patients without psoriasis who met the criteria for analysis. After propensity score matching, each cohort included 20,660 patients with a mean age of 60 years. During the 5-year observation period, 2725 patients in the psoriasis cohort experienced MACE compared with 2203 patients in the non-psoriasis cohort (OR, 1.40; 95% CI, 1.317-1.488).
“This was an unexpected outcome that challenges the current understanding and highlights the need for further research into tailored treatments for cardiovascular risk in psoriasis patients,” Dr. Ormaza Vera told this news organization.
She acknowledged certain limitations of the study, including its retrospective design, the inherent limitations of an observational study, and the use of electronic medical record data.
Lawrence J. Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”
The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

FROM SID 2024
Another Reason to Control Lp(a): To Protect the Kidneys Too
LYON, FRANCE — High levels of lipoprotein(a) [Lp(a)] in the blood are associated with a significantly increased risk for chronic kidney disease, report investigators who are studying the link in a two-part study of more than 100,000 people.
There is already genetic evidence showing that Lp(a) can cause cardiovascular conditions, including myocardial infarction, aortic valve stenosis, peripheral artery disease, and ischemic stroke.
Now, researchers presenting at the European Atherosclerosis Society (EAS) 2024 Congress are adding new organs – the kidneys – to the list of those that can be damaged by elevated Lp(a).
“This is very important,” said lead investigator Anne Langsted, MD, PhD, DMSc, from the Department of Clinical Biochemistry at the Rigshospitalet in Denmark. And “hopefully, we’ll have a treatment for Lp(a) on the market very soon. Until then, I think individuals who have kidney disease would benefit a lot from reducing other risk factors, if they also have high levels” of Lp(a).
Using data gathered from the Copenhagen General Population Study, the study involved 108,439 individuals who had a range of tests including estimated glomerular filtration rate (eGFR), plasma Lp(a) levels, and LPA genotyping. The patients were then linked to a series of national registries to study outcomes.
The researchers conducted two separate analyses: an observational study of Lp(a) levels in 70,040 individuals and a Mendelian randomization study of LPA kringle IV–type 2 domain repeats in 106,624 individuals. The number of those repeats is inversely associated with median Lp(a) plasma levels.
The observational study showed that eGFR decreased with increasing median plasma Lp(a) levels; the Mendelian randomization study indicated that eGFR decreased KIV-2 repeat numbers dropped.
Across both parts of the study, it was found that each 50 mg/dL increase in plasma Lp(a) levels was associated with an increased risk of at least 25% for chronic kidney disease.
Lp(a) and Chronic Kidney Disease
When high plasma levels of Lp(a) have been spotted before in patients with kidney disease, “we’ve kind of assumed that it was probably the kidney disease that caused the higher levels,” Dr. Langsted said. But her team hypothesized that the opposite was at play and that Lp(a) levels are genetically determined, and increased plasma Lp(a) levels may be causally associated with rising risk for chronic kidney disease.
Gerald F. Watts, MD, PhD, DSc, Winthrop Professor of cardiometabolic and internal medicine at the University of Western Australia in Perth, and co-chair of the study, said in an interview that “although Mendelian randomization is a technique that allows you to infer causality, it’s probably a little bit more complex than that in reality,” adding that there is likely a bidirectional relationship between Lp(a) and chronic kidney disease.
Having increased Lp(a) levels on their own is not sufficient to trigger chronic kidney disease. “You probably need another event and then you get into a vicious cycle,” Dr. Watts said.
The mechanism linking Lp(a) with chronic kidney disease remains unclear, but Dr. Watts explained that the lipoprotein probably damages the renal tubes when it is reabsorbed after it dissociates from low-density lipoprotein cholesterol.
The next step will be to identify the people who are most susceptible to this and figure out what treatment might help. Dr. Watts suggested that gene silencing, in which Lp(a) is “completely obliterated,” will lead to an improvement in renal function.

Counting Steps or Watching the Clock for a Longer Life?
Exercise recommendations typically focus on the duration of physical activity. For example, the World Health Organization advises at least 150 minutes of moderate physical activity per week. A new analysis of data from the Women’s Health Study, published in JAMA Internal Medicine, suggested that step count could also be a useful metric. For some, such a recommendation might be easier to follow.
“It’s not so easy to keep track of how long you’ve been moderately active in a given week,” Cary P. Gross, MD, from the Department of Medicine at Yale University in New Haven, Connecticut, wrote in an editorial. “Counting steps might be easier for some people, especially since most carry a phone that can serve as a pedometer.”
The 10,000-Step Recommendation
However, there are no well-founded recommendations for step counts, partly due to a lack of scientific evidence linking steps with mortality and cardiovascular diseases. The often-cited 10,000 steps per day originated from a marketing campaign in Japan in the 1960s.
The research team led by Rikuta Hamaya, MD, from the Division of Preventive Medicine at Brigham and Women’s Hospital in Boston, analyzed data from participants in the Women’s Health Study. This clinical trial in the United States from 1992 to 2004 investigated the use of aspirin and vitamin E for cancer and cardiovascular disease prevention.
The current analysis included 14,399 women who were aged ≥ 62 years and had not developed cardiovascular disease or cancer. Between 2011 and 2015, they measured their physical activity and step count over 7 days using an accelerometer. They were followed-up for an average of 9 years.
Risk Reduction With Both Parameters
Moderate physical activity among the participants amounted to a median of 62 minutes per week, with a median daily step count of 5183. Hamaya and his colleagues found that both physical activity parameters were associated with lower mortality and reduced risk for cardiovascular diseases.
Participants who engaged in more than the recommended 150 minutes of moderate-intensity activity per week had a 32% lower mortality risk than those who were the least physically active. Women with > 7000 steps per day had a 42% lower mortality risk than those with the lowest daily step count.
Women in the top three quartiles of physical activity outlived those in the lowest quartile by an average of 2.22 months (time) or 2.36 months (steps), according to Hamaya and his team. The survival advantage was independent of body mass index.
For the endpoint of cardiovascular diseases (heart attack, stroke, and cardiovascular mortality), the researchers observed similar results as for mortality.
More Ways to Reach the Goal
Dr. Hamaya emphasized the importance of offering multiple ways to meet exercise recommendations: “For some, especially younger people, physical activity includes sports like tennis, soccer, walking, or jogging. All these can be tracked well with step counting. But for others, activity means cycling or swimming, which is easier to measure by duration.”
For Dr. Gross, the new findings provide a basis for using step counts to set physical activity goals — both in individual patient counseling and in formal guidelines. However, he stressed that further studies are necessary.
“The results need to be replicated in various populations, not just among men and younger people but also among ethnic minorities and lower-income populations, who often have less time and space for structured physical activity.”

“The results need to be replicated in various populations, not just among men and younger people but also among ethnic minorities and lower-income populations, who often have less time and space for structured physical activity.”

Discussing a Silent Problem: Communicating Effectively About Lipid Risks and Management
This transcript has been edited for clarity.
Jorge Plutzky, MD: Hi. I'm Dr Jorge Plutzky, director of preventive cardiology at the Brigham and Women's Hospital, and in that setting I direct our lipid clinic. I'm pleased to be here today to talk about how we communicate about cholesterol. And I'm pleased to be able to do that today with a patient of mine, Brian McMahon.
Brian, thank you for being here.
Brian McMahon: Thank you, Doctor.
Plutzky: Why don't you tell people listening how we came to connect in the first place.
McMahon: Well, it was around statins. I had been prescribed one probably 10 years ago, and I had an adverse reaction to it — a violent reaction. And the doctor just told me to stop taking it. So I did. And I never asked another question.
And then 10 years later, my GP in Connecticut said, "You should go get a calcium score exam. Insurance doesn't cover it. It's 90 bucks, and it'll be the best 90 bucks you ever spent." And then the numbers were not good. That led me to come and talk to you about what do I do now? What are my options? I had an adverse reaction to statins. I didn't think I could even take them.
Plutzky: That's so important. Really, the failure was in your physician not getting that initial follow-up: Okay, so you had this reaction; what are the potential explanations for that, and what could be the next steps?
It really should not fall upon you as a patient to have to push that. But in fact, when people are better educated about the issues in our system, sometimes you do have to be your own advocate and ask, "What's next?" And it's important for us in communicating these issues during that first encounter, which might be with a primary care physician or a cardiologist, but more often it's with a primary care physician.
We're more motivated when someone's already had an event — secondary prevention. Let's not have another one because the patient has now been through something scary: a heart attack or a stent or even bypass surgery or a stroke. Those really motivate people. But even in that setting, we often find that patients don't necessarily stay on treatment or don't necessarily get treated aggressively enough to the right LDL level.
So that becomes important to set the stage early about why we are doing this, and let's come up with options that are safe, usually well tolerated, and have been extensively studied.
McMahon: I think the key is that it is a silent killer, so you don't feel bad, you don't have a rash, you don't have a scratch. It's not painful, but it could kill you. But the very fact that it's just that the statin doesn't agree with you — that was a real mess, in my estimation.
Plutzky: Often in settings of primary prevention, you're trying to conjure up the future for someone, saying, "You know what? If we don't do something, we're going to run into issues." But those patients don't feel bad. You're right that it is silent, but that's where the huge opportunity exists: early intervention — identifying what that risk is and how many different options we have, like if someone doesn't succeed on or has an issue with a statin. We know that's uncommon, but people often do well with some of these other alternatives, including just a different statin, which was the case with you.
McMahon: Right. And I had no idea that that was even available to me. That was an eye-opener, that there are options available to me, that I can find different things that work; but for goodness' sake, you should be on it.
Plutzky: Yes, we often have patients do well on a statin. Some patients really can't take a statin.
We'll go through a couple different options. I often will lay out for people who think they're having an issue with the statin that there are three possibilities: One, it's not the statin, because in the clinical trials we see people who quit the placebo as often as they quit the statin. Sharing that with patients matters. It's possible that what one felt wasn't even related to the statin. Two, sometimes reactions are statin specific. We try a different statin and then someone does well. Sometimes that may be influenced by the fact that we've laid out the data and explained to a patient, "We know that statins are safe, effective, and well tolerated, and here's the benefit for you down the road."
Is that part of why that second statin now works? It's hard to know. I've had many physician patients who say, "I didn't feel great on that one, but now I'm on a different statin and I'm feeling, much better." So, everyone reacts differently.
McMahon: I love that you walked me into it too. It wasn't just, "Here's 20 mg. We started at 5 mg, then we went to 10 mg, now we're at 20 mg." You took the time to say, "I hear you and I heard what happened to you. So, let's walk into this." I lost 10 years of taking statins, which would have put me in a different place.
Plutzky: The fact is that the first dose of the statin has the biggest impact on reducing your LDL. And then as you titrate it up, which we do all the time — we have with you — the effect on the lowering of LDL is less impactful. That's why it can be a way in with people to say, "Let's start with this low dose." At least they're on something. And people often say, "Wow! I really feel completely fine on this." There are people who either just can't take a statin at all or who, once they're on the statin, aren't getting to a low enough or appropriate LDL number, and it's good to have those alternatives.
One of them is specifically theoretically designed for people who think they've had muscle issues with statin. Your issues were different, but bempedoic acid is an alternative. And even going beyond that, we now have injectable medicines that really are very effective at bringing down LDL.
When people hear injections, they're like, "Oh my gosh, I don't want to take an injection," but explain to people how easy it is to do those injections. It's basically just a pen against your skin. That really reduces their fear and their anxiety. But it's important to realize that we do have many tools for lowering LDL. If someone runs into a problem with the statin that you can't overcome, then it's important to move on.
So we should recognize how important it is to lower LDL. Realizing how many tools we have allows people to begin working through the process where the objective is: I want to get my LDL down, and if we can do it with a statin, then we're taking advantage of all this data we have about their benefits. But if that turns out not to work for a given patient, even after trying and explaining things, then let's move on. But let's get to that ultimate goal of lowering LDL as one component of risk.
I think there's nothing more empowering for the person you're dealing with than to share with them what it is that you know; that you know, based upon medical science and clinical trials, what that rationale is, because no one is trying to hurt themselves. If someone comes in who doesn't want to take a statin, it's not because they're trying to have a heart attack. They're not trying to hurt themselves. There's some barrier to what's motivating them, to what's keeping them from this therapy. We just have to better communicate what the goal is and what the basis is for pursuing this, and then finding your way through the woods of saying, "Well, that worked great and we've made it" vs "We've run into something, so let's go on a different path."
McMahon: I think that to me was the light-bulb moment, which was that experience with statin: Don't take it anymore. And then 10 years go by and now I'm in trouble. And then I find out that there is a wealth of opportunities. There are so many arrows in your quiver — not to make a Cupid joke, but there are so many arrows available to fix this, and I didn't know it. Now I do.
Plutzky: Yes, it's empowering. I think there's a challenge for us as caregivers to more broadly share what we know so that people are motivated and empowered to say, "I want to get treated. I want to do better. And I understand the extent to which this is a risk for me if I don't do better."
McMahon: Right.
Plutzky: So often there's a family history associated with that, too. Sometimes when I'm communicating with patients the idea of "You need to do this," especially patients with young kids, I'm communicating, "How you eat and your activity level is sending a very powerful message to your kids."
McMahon: Yes.
Plutzky: We're trying to eat healthy. We're more oriented toward vegetables. We're being active. Let's go for a walk. Let's go for a family run. Let's have a sport that we do together. Or even just the kids seeing you leave the house to say, "I'm off." "Where are you going, Dad?" "I'm going to play tennis." "Can I come with you?" And then…
McMahon: It creates a lifestyle.
Plutzky: Yes.
McMahon: Well, it comes back to: You have one heart.
Plutzky: Yes. Well, it's been a pleasure to have a chance to discuss what are really important topics. I mean, this is really impactful. Far beyond just your experience, it's the chance for other people to realize that these are issues that need to be recognized, dealt with; that people need to be empowered; and that ultimately it comes down to us about how to better communicate.
I'm always very focused on how can a patient know what I know and what I think matters based upon evidence, data, clinical trials. How do we share that and share that in very limited time windows? It's been a privilege to work with you, Brian, in a clinical setting, and I'm very appreciative of your taking the time to join us today.
McMahon: Thank you for getting me on the right path. I'm grateful.
Plutzky: Well, you've done that for yourself. Good talking to you.
McMahon: Likewise.

Roche Blood Test for Lp(a) Designated Breakthrough Device
The Tina-quant Lp(a) RxDx assay, developed by Roche in partnership with Amgen, is designed to identify adults with elevated Lp(a) levels who may benefit from lipid-lowering therapies currently in development.
Lp(a) is a type of lipoprotein that is genetically inherited. Elevated levels have been associated with an increased risk for heart disease, stroke, and other blood vessel diseases.
Worldwide, about 1 in 5 people have high Lp(a) levels that are not significantly affected by lifestyle changes, such as diet and exercise. Elevated Lp(a) is particularly prevalent among women and people of African descent.
Lp(a) testing is “an important tool for clinicians, enabling them to make a more accurate assessment of [cardiovascular] risk, and it is expected to become a part of regular diagnostic testing in the coming years,” Roche said in a news release announcing the breakthrough designation for the Lp(a) blood test.
If approved, the Tina-quant Lp(a) RxDx assay will be available on select Roche cobas platforms, the company reported.
Although low-density-lipoprotein (LDL) cholesterol particles are much more abundant than Lp(a) particles and carry the greatest overall risk for heart disease, on a per-particle basis, atherogenic risk associated with Lp(a) is about six times higher than that associated with LDL cholesterol, a recent study showed.
There currently are no approved pharmacologic therapies to lower Lp(a) levels in the United States, but several hopefuls are in development.
One is zerlasiran (Silence Therapeutics), a short interfering RNA (siRNA) agent, or “gene silencing” therapy, which binds to and temporarily blocks the action of the LPA gene, which encodes for apolipoprotein A, a dominant and rate-limiting component in the hepatic synthesis of the Lp(a) particle.
Treatment with zerlasiran produced significant and sustained reductions in Lp(a) concentrations in adults with elevated Lp(a) in the phase 1 APOLLO trial and the phase 2 ALPACAR-360 trial.
Other siRNA agents in development to lower Lp(a) levels include pelacarsen, lepodisiran, olpasiran, and muvalaplin.

The Tina-quant Lp(a) RxDx assay, developed by Roche in partnership with Amgen, is designed to identify adults with elevated Lp(a) levels who may benefit from lipid-lowering therapies currently in development.
Lp(a) is a type of lipoprotein that is genetically inherited. Elevated levels have been associated with an increased risk for heart disease, stroke, and other blood vessel diseases.
Worldwide, about 1 in 5 people have high Lp(a) levels that are not significantly affected by lifestyle changes, such as diet and exercise. Elevated Lp(a) is particularly prevalent among women and people of African descent.
