Aggressive lowering of LDL cholesterol: Is it a good idea?

Article Type

– Powerful drugs now make it possible to lower LDL cholesterol levels to dramatically low levels. But is this a good idea? There are risks, and a cardiologist urged diabetes professionals to not overdo cholesterol reduction. But a colleague argued in favor of aggressively targeting “bad” cholesterol.

“We used to say you can’t be too rich or too thin. We now say you can’t be too rich or too thin or have a too-low LDL cholesterol,” said cardiologist Steven E. Nissen, MD, chairman of cardiovascular medicine at the Cleveland Clinic Foundation, who spoke at the annual scientific sessions of the American Diabetes Association about the wisdom of extreme LDL cholesterol lowering.

Dr. Nissen faced off in a debate with cardiologist Sanket Dhruva, MD, of the University of California, San Francisco, who doesn’t support aggressive LDL cholesterol lowering.

It is fine, Dr. Dhruva said, to treat patients so their LDL cholesterol levels drop below 100 mg/dL. “I don’t think there’s any argument there.”

But Dr. Dhruva questioned whether it’s a good idea to generally decrease LDL cholesterol well below 70 mg/dL, as is now possible with the use of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors.

Dr. Sanket Dhruva


He pointed to a 2010 study that found aggressively lowering LDL cholesterol led to a mean net gain of 4.1 quality-adjusted life-years in high-risk patients, but less than 1 quality-adjusted life-year in low-risk patients. According to him, the study also found that the biggest benefits in both high- and low-risk patients came from the initial lower statin dose (Arch Intern Med. 2010 Jun 28;170[12]:1037-44).

“It’s really the statin initiation that provides the most benefit to our patients with diabetes,” Dr. Dhruva said.

Also, he added, a 2016 study questioned the value of aggressively lowering LDL cholesterol. It found that, although patients on statins with LDL cholesterol levels of 70-100 mg/dL had a lower risk of adverse cardiac outcomes than did those with levels between 100 and 130 mg/dL, no additional benefit was gained by achieving an LDL cholesterol level below 70 mg/dL (JAMA Intern Med. 2016 Aug 1;176[8]:1105-13)


As for risks, Dr. Dhruva highlighted a 2016 pooled analysis of 14 trials that linked the PCSK9 inhibitor alirocumab (Praluent) and LDL cholesterol levels below 25 mg/dL to significantly higher levels of cataracts, compared with levels of at least 25 mg/dL (hazard ratio, 3.4).

There are other reasons to be cautious of aggressive LDL cholesterol lowering. For one, many patients are not on statins when they’re prescribed PCSK-9 inhibitors. “We’re sometimes missing the building blocks before getting to expensive medications,” he said.

He added that PCSK-9 inhibitors are pricey, and some patients can’t get access to them. “Lipid control is incredibly important, but what about the stress or anxiety of our patients who are told this medication will reduce their cardiac risk but they can’t afford it? That’s not good for their cardiovascular risk.”

For his part, Dr. Nissen challenged Dr. Dhruva’s concerns about the cost of the drugs. “It’s not like they’re way out of line in terms of expense,” he said, noting that their cost – several thousand dollars a year – is similar to the cost of diabetes drugs known as glucagonlike peptide–1 receptor agonists and sodium-glucose transporter 2 inhibitors.

According to Dr. Nissen, multiple studies have supported aggressive LDL cholesterol lowering. “You’re going to see this over and over again in clinical trials: Every time we lower LDL by more, we get more reductions in morbidity and mortality.”

For example, he said, the FOURIER trial of the PCSK9 inhibitor evolocumab (Repatha) found that it lowered LDL cholesterol levels to a median 30 mg/dL “and reduced the risk of cardiovascular events. These findings show that patients with atherosclerotic cardiovascular disease benefit from lowering of LDL cholesterol levels below current targets [N Engl J Med 2017;376:1713-22].”

Dr. Nissen pointed to another study, this one also from 2017, that reported “in individuals with 5-year risk of major vascular events lower than 10%, each 1 mmol/L reduction in LDL cholesterol produced an absolute reduction in major vascular events of about 11 per 1,000 over 5 years. This benefit greatly exceeds any known hazards of statin therapy.”

In regard to adverse effects, he said, research has hinted at a slight uptick in blood sugar levels “that does not take away the major cardiovascular benefits of the drugs.”

Overall, he said, “compelling evidence from trials in hundreds of thousands of patients demonstrates that reducing LDL cholesterol to very low levels reduces cardiovascular events in broad populations and is extremely safe.”

Dr. Nissen reported consulting for many pharmaceutical companies and performing clinical trials for Amgen, AbbVie, AstraZeneca, Cerenis Therapeutics, Esperion Therapeutics, Lilly, Novartis, Novo Nordisk, the Medicines Company, Orexigen Therapeutics, Takeda, and Pfizer. He does not receive income for honoraria, speaking fees, or consulting fees as they are paid directly to charity.

Genetic analysis links PCSK9 inhibition and CV mortality

Analysis first to show cardiovascular mortality benefit
Article Type
Changed

 

Long-term genetically low levels of LDL cholesterol, by means of functional variants in the PCSK9 gene, were associated with a reduced risk of CV mortality, but not all-cause mortality, in a large cohort of individuals.

“We tested the hypothesis that genetically low LDL cholesterol due to PCSK9 [proprotein convertase subtilisin/kexin type 9] variation is causally associated with low cardiovascular and all-cause mortality in a general population of Northern European ancestry,” wrote Marianne Benn, MD, DMSc, and colleagues. The findings were published in the Journal of the American College of Cardiology.

The researchers conducted a large-scale genetic analysis of 109,566 persons from the Copenhagen City Heart Study and Copenhagen General Population Study. In addition, the team included a validation cohort of 431,043 individuals from the UK Biobank.

The median duration of follow-up was 10 years (0-42 years), and the median age at study entry was 57 years.

Study participants were genotyped for several PCSK9 variants and a weighted allele score based the effects of LDL cholesterol, individual allele frequency, and number of variant alleles was calculated for each subject.



Weighted scores were categorized into five stepwise noncontinuous score ranges, with lower levels of LDL cholesterol linked to higher allele scores.

After analysis, the researchers found that a growing number of PCSK9 alleles were associated with lower levels of LDL cholesterol up to 0.61 mmol/L (P for trend less than .001) and reduced CV mortality (P = .001), but not with reduced all-cause mortality (P = .11).

“Our genetic data did not show a reduction in risk of all-cause mortality, and only showed a reduction in risk of all-cause mortality in statin trials and not in the PCSK9-inhibitor trials meta-analyzed,” the researchers wrote. “This may be explained by the low frequency of cardiovascular disease in the 2 populations studied,” they explained.

One key limitation was the homogeneous makeup of the study population. Dr. Benn and colleagues acknowledged this could limit the generalizability of the results.

“Long-term LDL cholesterol treatment (e.g., with PCSK9 inhibitors), may translate into reductions in cardiovascular mortality,” they concluded.

The study was supported by the Danish Council for Independent Research, Medical Sciences, Johan Boserup, and the Lise Boserup’s Fund. The authors reported no conflicts of interest.

One question that remains from the current study is whether prolonged inhibition of PCSK9 in patients with increased LDL cholesterol levels will reduce cardiovascular mortality in the context of primary and secondary prevention.

The recent development of PCSK9 inhibitors was heavily influenced by genetic analyses showing that person-specific variants in the PCSK9 gene could lower LDL levels and reduce rates of coronary heart disease. Because of the rarity of these gene variants, their impact on mortality on a large-scale basis remains unclear.

Although numerous clinical trials have shown that PCSK9 inhibition can reduce CVD-related events in both chronic and high-risk patients, no study has clearly shown an effect on cardiovascular death. However, the relationship between lipid levels and clinical outcomes is difficult to assess owing to the presence of confounding factors. Certain types of genetic analysis may help eliminate these challenges by analyzing large populations over extended periods of time.

The genetic analysis by Dr. Benn and colleagues showed an association between long-term exposure to lower levels of LDL cholesterol, by means of functional variants in the PCSK9 gene, and reduced cardiovascular mortality. These findings, alongside other studies, provide further support for the relationship between PCSK9 inhibition and prevention of cardiovascular mortality.

Three out of five ain’t bad? Some diabetes measures improved over 17 years

Article Type
Changed

 

– New research suggests that the health of Americans with diabetes changed markedly in the past 2 decades, improving on three out of five fronts.

As the age of statins dawned, cholesterol levels dipped dramatically, while blood pressure levels and smoking prevalence also fell. But hemoglobin A1c levels stubbornly stayed steady, and obesity rates ballooned.

In light of the not entirely impressive numbers, “maybe we need to follow the model of team collaboration we see in the heart care setting,” said study lead author Carla I. Mercado, PhD, an epidemiologist with the Centers for Disease Control & Prevention. She spoke in an interview at the annual scientific sessions of the American Diabetes Association, where she presented the study findings.

For the new study, Dr. Mercado and colleagues used data from the National Health and Nutrition Examination Survey (NHANES) to track the health of adults with diabetes in the United States during 1999-2016. “With all the efforts on diabetes care management, we wanted to see if our efforts are making a difference in the population,” Dr. Mercado said.



The 5,534 participants had self-reported diabetes, were not pregnant, and underwent a physical examination. Throughout the periods examined (1999-2004, 2005-2010, and 2011-2016), the proportion of women remained steady at about one-half. So did the racial makeup, which ranged from 59% to 63% non-Hispanic white, 15% to 18% black, 7% to 10% Mexican-American, and 12% to 15% “other.”

Nearly half were aged 45-64, and 89%-90% had health insurance. There was a significant change in the education levels among those aged 25 and older: The percentage with at least a college degree grew from 14% in 1999-2004 to 21% in 2011-2016, while those with less than a high-school diploma fell from 34% to 23% over that period.

From 1999-2004 to 2011-2016

  • Cholesterol: Most notably, the percentage of participants with non-HDL cholesterol levels below 130 mg/dL soared, from 30% to 54%. The CDC considers levels less than 100 mg/dL to be ideal. “I’m sure this is driven by medication use,” Dr. Mercado said.
  • Smoking: The percentage of never smokers rose, from 44% to 47% of the subjects, while that of current smokers dropped, from 26% to 21%, a significant difference.
  • Hypertension: The percentages with blood pressure levels less than 120/80 mm Hg – considered normal levels by the CDC – rose significantly, from 26% to 30%. “People are a lot more aware of blood pressure,” Dr. Mercado said.
  • Glycemic control: HbA1c levels stayed roughly steady. About 10% had levels at or above 10% in both 1999-2004 and 2011-2016, and the number with A1c levels below 6% dipped slightly from 19% to 17%.
  • Obesity: The proportion of participants with body mass index levels at or above 30 kg/m2, the line between overweight and obese, rose from 54% to 61%. The percentage of those with BMIs below 25 kg/m2 – considered to have normal weights – fell significantly, from 17% to 12%.

The researchers also looked at the percentage who reached ABCS goals (A1c at or below 9%, blood pressure below 140/90 mm Hg, non-HDL cholesterol under 160 mg/dL, and current nonsmoking status). The percentage who met all of these criteria grew from 26% to 40%, while those who met three of them stayed steady (40%-39%).

The study was funded by the CDC. The study authors report no relevant disclosures.

In light of the not entirely impressive numbers, “maybe we need to follow the model of team collaboration we see in the heart care setting,” said study lead author Carla I. Mercado, PhD, an epidemiologist with the Centers for Disease Control & Prevention. She spoke in an interview at the annual scientific sessions of the American Diabetes Association, where she presented the study findings.

For the new study, Dr. Mercado and colleagues used data from the National Health and Nutrition Examination Survey (NHANES) to track the health of adults with diabetes in the United States during 1999-2016. “With all the efforts on diabetes care management, we wanted to see if our efforts are making a difference in the population,” Dr. Mercado said.



The 5,534 participants had self-reported diabetes, were not pregnant, and underwent a physical examination. Throughout the periods examined (1999-2004, 2005-2010, and 2011-2016), the proportion of women remained steady at about one-half. So did the racial makeup, which ranged from 59% to 63% non-Hispanic white, 15% to 18% black, 7% to 10% Mexican-American, and 12% to 15% “other.”

Nearly half were aged 45-64, and 89%-90% had health insurance. There was a significant change in the education levels among those aged 25 and older: The percentage with at least a college degree grew from 14% in 1999-2004 to 21% in 2011-2016, while those with less than a high-school diploma fell from 34% to 23% over that period.

From 1999-2004 to 2011-2016

  • Cholesterol: Most notably, the percentage of participants with non-HDL cholesterol levels below 130 mg/dL soared, from 30% to 54%. The CDC considers levels less than 100 mg/dL to be ideal. “I’m sure this is driven by medication use,” Dr. Mercado said.
  • Smoking: The percentage of never smokers rose, from 44% to 47% of the subjects, while that of current smokers dropped, from 26% to 21%, a significant difference.
  • Hypertension: The percentages with blood pressure levels less than 120/80 mm Hg – considered normal levels by the CDC – rose significantly, from 26% to 30%. “People are a lot more aware of blood pressure,” Dr. Mercado said.
  • Glycemic control: HbA1c levels stayed roughly steady. About 10% had levels at or above 10% in both 1999-2004 and 2011-2016, and the number with A1c levels below 6% dipped slightly from 19% to 17%.
  • Obesity: The proportion of participants with body mass index levels at or above 30 kg/m2, the line between overweight and obese, rose from 54% to 61%. The percentage of those with BMIs below 25 kg/m2 – considered to have normal weights – fell significantly, from 17% to 12%.

The researchers also looked at the percentage who reached ABCS goals (A1c at or below 9%, blood pressure below 140/90 mm Hg, non-HDL cholesterol under 160 mg/dL, and current nonsmoking status). The percentage who met all of these criteria grew from 26% to 40%, while those who met three of them stayed steady (40%-39%).

The study was funded by the CDC. The study authors report no relevant disclosures.

Which antidiabetic for elderly patients? It depends on their CV risk

Article Type
Changed

 

– SGLT2 inhibitors did a better job than GLP-1 receptor agonists at preventing heart failure hospitalizations in elderly patients with type 2 diabetes, but at the cost of more strokes, myocardial infarctions, and deaths among those without preexisting cardiovascular disease, according to Harvard University investigators.

Using Medicare claims data and propensity scoring, they matched 43,609 elderly patients who started a sodium-glucose cotransporter 2 (SGLT2) inhibitor for type 2 diabetes, 77% of whom were taking canagliflozin (Invokana), to 43,609 who started a glucagonlike peptide–1 (GLP-1)–receptor agonist, 60% of whom were taking liraglutide (Victoza).

Patients were paired by age, comorbidities, diabetes severity, and dozens of other variables, more than 120 in all. The data window ran from April 2013 through December 2016.

The idea was to compare the drugs directly in order to help clinicians decide which class to choose for older patients as second-line therapy, an important consideration at a time when there’s not much guidance specifically for the elderly, and manufacturers are issuing dueling placebo-controlled trials.

Both classes have shown cardiovascular benefits, but studies were mostly in younger people with preexisting cardiovascular disease (CVD). “The comparative impact of these agents in the older population has not yet been established,” lead investigator Elisabetta Patorno, MD, DrPH, of Harvard University, Boston, said at the annual scientific sessions of the American Diabetes Association.

General themes are emerging from Dr. Patorno’s work; it seems that deciding between the two classes has a lot to do with whether the main concern is heart failure or cardiovascular events. Even so, she said, it’s too early to incorporate the observations into guidelines. The analysis is ongoing, and there are plans to compare impacts on renal disease and other problems.



In the meantime, she and her colleagues found that initiating an SGLT2 inhibitor versus a GLP-1 receptor agonist in the elderly was associated with a 34% decreased risk of heart failure hospitalization (2.5 fewer hospitalizations per 1,000 patient years), with an even larger drop among people who had preexisting CVD.

There was, however, a 41% increased risk of lower limb amputations (0.8 more events per 1,000 patient years) and a 62% increase in diabetic ketoacidosis (DKA, 1 more event), problems previously associated with the class.

Results were comparable – fewer heart failure hospitalizations but more amputations and DKA – when SGLT2 initiation was compared to initiation with dipeptidyl peptidase-4 (DPP-4) inhibitors, another second-line option for type 2 diabetes that includes sitagliptin (Januvia), among others.

There was a 25% increased relative risk of the composite primary outcome of myocardial infarction, stroke, and all-cause mortality when patients without baseline CVD were started on an SGLT2 inhibitor instead of a GLP-1 receptor agonist (3.7 more events per 1,000 patient years). There was no increased risk among patients who already had CVD.

SGLT2 initiation actually had a protective effect, compared with dipeptidyl peptidase-4 inhibitors, with a 23% decreased risk of the composite outcome (6.5 fewer events) among patients both with and without baseline CVD. The findings were all statistically significant.

The average age in the study was 71.5 years; 45% of the subjects were men; 40% had a history of cardiovascular disease; and 60% were on metformin and 24% on insulin at study entry.

The work was funded by the National Institutes of Health. Dr. Patorno disclosed research grants form Boehringer Ingelheim and GlaxoSmithKline. Other investigators reported relationships with numerous pharmaceutical companies.

GLP-1 RA dulaglutide yields cardiac gains, even in non–at-risk patients

Article Type
Changed

– A large, long-term study is linking yet another glucagon-like peptide–1 receptor agonist diabetes drug to positive cardiovascular outcomes: Patients with type 2 diabetes and heart disease risk factors who took dulaglutide for about 5 years during the REWIND study had a 12% lower risk of major adverse cardiovascular events, compared with those who took placebo.

These new findings on cardiac risk are unusual compared with other newer-generation diabetes drugs, because a high percentage of the participants did not have existing cardiovascular disease. In addition, the study population had a higher percentage of women, compared with previous studies.

“We feel very strongly that the participants were similar to the ... ambulatory patients with type 2 diabetes with cardiovascular risk who are routinely seen in clinical practice,” study coauthor Jeffrey L. Probstfield, MD, of the University of Washington, Seattle, saidin a presentation at the annual scientific sessions of the American Diabetes Association. The findings were published simultaneously in The Lancet (2019 Jun 10. doi: 10.1016/S0140-6736(19)31149-3.

Dulaglutide’s serious adverse-effect profile was similar to that of placebo, the study authors noted, and the drug also showed benefits in renal outcomes, as reported in a separate study (Gerstein HC et al. Lancet. 2019 Jun 10. doi: 10.1016/S0140-6736(19)31150-3.

The Food and Drug Administration has mandated that six glucagon-like peptide–1 receptor agonists (GLP-1 RAs) – albiglutide (Tanzeum), exenatide (Byetta), liraglutide (Victoza), lixisenatide (Adlyxin), semaglutide (Ozempic) and dulaglutide (Trulicity) – undergo testing of cardiovascular outcomes. Dulaglutide is the fourth, following albiglutide, liraglutide, and semaglutide, to show consistent, statistically significant reduction in major adverse cardiovascular events (MACE).

For the double-blind, randomized, placebo-controlled REWIND study, researchers recruited 9,901 participants who were at least 50 years old with type 2 diabetes, a hemoglobin A1c (HbA1c) level of 9.5% or less, and a body mass index of more than 23 kg/m2. The participants came from 371 sites in 24 countries, including the United States and Canada. More than 80% were taking an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker, and other blood pressure drugs were also common.

The average mean age was 66 years; 46% of the participants were women, three-quarters were white, and 31% had previous cardiovascular disease. Previous GLP-1 RA studies of this type had markedly lower percentages of women – the other studies comprised 30%-39% women – and included higher percentages of participants with previous cardiovascular disease (73%-100%).

Of the participants in the current study, 4,949 were assigned to receive dulaglutide and 4,952 to receive placebo. They were followed for a median 5.4 years. About 57% never stopped using the drug, and 11% of those in the drug group and 7.5% in the placebo group stopped use because of adverse effects.

In regard to diabetes outcomes, HbA1c levels fell in the drug group by a mean –0.61% (95% confidence interval, –0.65 to –0.58; P less than .0001), compared with placebo. Their weight decreased by a mean –1.5 kg (95% CI, -1.7 to -1.3; P less than .0001) Systolic blood pressure and LDL cholesterol levels were slightly lower in the drug group, but heart rate was higher.

On the heart front, MACE fell by 12% in the drug group, compared with placebo (hazard ratio, 0.88; 95% CI, 0.79-0.99; P = .026). “The effect of the intervention begins [within] the first year and continued in a progressive, proportional fashion throughout the follow-up period,” said study lead author Hertzel C. Gerstein, MD, of McMaster University and Hamilton Health Sciences, Hamilton, Ont.

There was an especially large decline in the number of nonfatal stroke cases in the drug group, compared with placebo (135 vs. 175, respectively; HR, 0.76; 95% CI, 0.61-0.95; P = .017). The drug did not have a statistically significant effect on cardiovascular death.

The researchers found no difference in the drug’s effects on MACE in subgroups including age, gender, ethnicity, duration of diabetes, and history of cardiovascular disease.

They also reported a decline in a renal composite outcome (first macroalbuminuria, sustained decline in estimated glomerular filtration rate of 30% or more, chronic renal replacement) in the drug group (HR, 0.85; 95% CI, 0.77-0.93; P = .0004).

Rates of serious adverse effects were similar in the drug and placebo groups. Gastrointestinal adverse effects – including nausea, constipation, and diarrhea – were as expected, Dr. Gerstein said.

“The addition of dulaglutide could be considered for both primary and secondary cardiovascular prevention in middle-aged patients with type 2 diabetes and cardiovascular risk factors,” Dr. Gerstein said.

In an independent commentary at the meeting presentation, Sophia Zoungas, MBBS (Hons), FRCP, PhD, of Monash University, Melbourne, praised the study and applauded the findings.

However, she called attention to the results that pinpointed higher levels of microvascular-related eye outcomes (HR, 1.24; 95% CI, 0.92-1.68) and fatal myocardial infarction (HR, 1.29; 95% CI, 0.72-2.30) in the dulaglutide group. Both of those outcomes were rare – 171 eye outcomes and 46 fatal myocardial infarctions overall. She also questioned whether the adherence rates would be as high in a real-world setting.

Eli Lilly funded the study. Three of the authors were employees of Eli Lilly, eight reported financial relationships with the company, five reported financial relationships with other firms, and the remaining authors reported no competing interests.

The findings were published simultaneously in The Lancet (2019 Jun 10. doi: 10.1016/S0140-6736(19)31149-3.

Dulaglutide’s serious adverse-effect profile was similar to that of placebo, the study authors noted, and the drug also showed benefits in renal outcomes, as reported in a separate study (Gerstein HC et al. Lancet. 2019 Jun 10. doi: 10.1016/S0140-6736(19)31150-3.

The Food and Drug Administration has mandated that six glucagon-like peptide–1 receptor agonists (GLP-1 RAs) – albiglutide (Tanzeum), exenatide (Byetta), liraglutide (Victoza), lixisenatide (Adlyxin), semaglutide (Ozempic) and dulaglutide (Trulicity) – undergo testing of cardiovascular outcomes. Dulaglutide is the fourth, following albiglutide, liraglutide, and semaglutide, to show consistent, statistically significant reduction in major adverse cardiovascular events (MACE).

For the double-blind, randomized, placebo-controlled REWIND study, researchers recruited 9,901 participants who were at least 50 years old with type 2 diabetes, a hemoglobin A1c (HbA1c) level of 9.5% or less, and a body mass index of more than 23 kg/m2. The participants came from 371 sites in 24 countries, including the United States and Canada. More than 80% were taking an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker, and other blood pressure drugs were also common.

The average mean age was 66 years; 46% of the participants were women, three-quarters were white, and 31% had previous cardiovascular disease. Previous GLP-1 RA studies of this type had markedly lower percentages of women – the other studies comprised 30%-39% women – and included higher percentages of participants with previous cardiovascular disease (73%-100%).

Of the participants in the current study, 4,949 were assigned to receive dulaglutide and 4,952 to receive placebo. They were followed for a median 5.4 years. About 57% never stopped using the drug, and 11% of those in the drug group and 7.5% in the placebo group stopped use because of adverse effects.

In regard to diabetes outcomes, HbA1c levels fell in the drug group by a mean –0.61% (95% confidence interval, –0.65 to –0.58; P less than .0001), compared with placebo. Their weight decreased by a mean –1.5 kg (95% CI, -1.7 to -1.3; P less than .0001) Systolic blood pressure and LDL cholesterol levels were slightly lower in the drug group, but heart rate was higher.

On the heart front, MACE fell by 12% in the drug group, compared with placebo (hazard ratio, 0.88; 95% CI, 0.79-0.99; P = .026). “The effect of the intervention begins [within] the first year and continued in a progressive, proportional fashion throughout the follow-up period,” said study lead author Hertzel C. Gerstein, MD, of McMaster University and Hamilton Health Sciences, Hamilton, Ont.

There was an especially large decline in the number of nonfatal stroke cases in the drug group, compared with placebo (135 vs. 175, respectively; HR, 0.76; 95% CI, 0.61-0.95; P = .017). The drug did not have a statistically significant effect on cardiovascular death.

The researchers found no difference in the drug’s effects on MACE in subgroups including age, gender, ethnicity, duration of diabetes, and history of cardiovascular disease.

They also reported a decline in a renal composite outcome (first macroalbuminuria, sustained decline in estimated glomerular filtration rate of 30% or more, chronic renal replacement) in the drug group (HR, 0.85; 95% CI, 0.77-0.93; P = .0004).

Rates of serious adverse effects were similar in the drug and placebo groups. Gastrointestinal adverse effects – including nausea, constipation, and diarrhea – were as expected, Dr. Gerstein said.

“The addition of dulaglutide could be considered for both primary and secondary cardiovascular prevention in middle-aged patients with type 2 diabetes and cardiovascular risk factors,” Dr. Gerstein said.

In an independent commentary at the meeting presentation, Sophia Zoungas, MBBS (Hons), FRCP, PhD, of Monash University, Melbourne, praised the study and applauded the findings.

However, she called attention to the results that pinpointed higher levels of microvascular-related eye outcomes (HR, 1.24; 95% CI, 0.92-1.68) and fatal myocardial infarction (HR, 1.29; 95% CI, 0.72-2.30) in the dulaglutide group. Both of those outcomes were rare – 171 eye outcomes and 46 fatal myocardial infarctions overall. She also questioned whether the adherence rates would be as high in a real-world setting.

Eli Lilly funded the study. Three of the authors were employees of Eli Lilly, eight reported financial relationships with the company, five reported financial relationships with other firms, and the remaining authors reported no competing interests.

Updated systematic review of aspirin primary prevention shows benefits, risks

Aspirin prophylaxis depends on individual decisions
Article Type
Changed

Using daily aspirin treatment for the primary prevention of cardiovascular events remains an individualized decision that needs to balance a person’s risks for ischemic events and bleeding, according to results from a new systematic review of 15 randomized, aspirin-prevention trials, including results from 3 major trials that researchers reported during 2018.

“The findings suggest that the decision to use aspirin for primary prevention should be tailored to the individual patients based on estimated atherosclerotic cardiovascular disease risk and perceived bleeding risk, as well as patient preferences regarding the types of event prevented versus potential bleeding caused,” Jawahar L. Mehta, MD, and his associates wrote in an article published on June 10 in the Journal of the American College of Cardiology.

The authors also concluded that if a person decides to use aspirin for primary prevention, then a low dose of 100 mg/day or less is recommended.


This new systematic review follows two reviews published earlier in 2019 that reached roughly similar conclusions after analyzing largely the same randomized trial data, including the same three major trials from 2018. One of these prior reviews included data from 13 trials and a total of 164,225 people (JAMA. 2019 Jan 22;321[3]:277-87). The second review had data from 11 trials with 157,248 people (Eur Heart J. 2019 Feb 14;40[7]:607-17). The newly published review used data collected by 15 trials from 165,502 people.

The three 2018 trials that triggered the updated data assessments were the ARRIVE trial, with 12,546 people randomized (Lancet. 2018 Sep 22;392[10152]:1036-46), the ASPREE trial, with 19,114 people randomized (New Engl J Med. 2018 Oct 18;379[16]:1509-18), and the ASCEND trial, with 15,480 people randomized (New Engl J Med. 2018 Oct 18;379[16]:1529-39).

As stated in the new report from Dr. Mehta, a professor of medicine at the University of Arkansas for Medical Sciences in Little Rock, and his associates, the recent trial results from 2018 added new data from more than 45,000 additional subjects, a development that warranted a reappraisal of the evidence for aspirin’s efficacy and safety for primary prevention in contemporary practice.

The major findings from the analysis by Dr. Mehta and his associates were that in adults without a history of cardiovascular disease, daily aspirin use reduced the incidence of MIs, with a number needed to treat (NNT) of 357; reduced ischemic stroke (NNT, 500), reduced transient ischemic attack (NNT, 370), and reduced the overall, combined rate of all major adverse cardiovascular events (NNT, 263). But on the safety side, daily aspirin led to an increased rate of major bleeding episodes, with a number needed to harm (NNH) of 222, increased intracranial bleeds (NNH, 1,000), and an increase in gastrointestinal bleeds (NNH, 385).

The analysis “demonstrates a potential reduction of net benefit with aspirin in the contemporary era,” the authors concluded. They also noted that the benefits from aspirin prevention were, as expected, “more pronounced” among people with a higher estimated risk from atherosclerotic cardiovascular disease.

The systematic review findings came against the backdrop of a recently released primary prevention guideline from the American College of Cardiology and American Heart Association (J Am Coll Card. 2019 Mar. doi: 10.1016/j.jacc.2019.03.010). The guideline said that aspirin prophylaxis for primary prevention “might be considered” for adults aged 40-70 years, but should not be used for people who are older than 70, and also should not be given to people with an increased risk for bleeding. In general, the experts who produced this guideline said that aspirin prophylaxis should be infrequent.

The new analysis also found no reduction in the incidence of cancer or cancer-related death linked with aspirin use for primary prevention. The systematic review published earlier in 2019 in JAMA also found no link between aspirin use and cancer incidence or mortality. The review from the European Heart Journal did not report on the link between aspirin use and cancer incidence or mortality.

Dr. Mehta has been a consultant to AstraZeneca, Bayer, Boehringer Ingelheim, Medimmune, and Pfizer, and has received grant support from AstraZeneca, Bayer, and Boehringer Ingelheim.

The three trials published in 2018 that added important new data on primary prevention for cardiovascular disease with aspirin must ideally be interpreted within the context of the totality of evidence on this subject. This was achieved in the analysis reported by Dr. Mehta and his associates, as well as in other more recent publications.

Making a decision about using aspirin for primary prevention in individuals based on trial data is very challenging because it requires weighing a modest potential benefit that people gain from daily aspirin for preventing a first cardiovascular event against the modest risk of an adverse bleeding event. It does not suffice simply to compare the number of cardiovascular and bleeding events, because those two types of events do not have the same immediate or long-term consequences. Each patient must make a personal choice between the risks and benefits.

The greatest potential benefit from aspirin prophylaxis seems to be in people with increased cardiovascular risk but with no increased bleeding risk. In general, this means people aged 50-59 years old, and also possibly those aged 60-69 years old if their estimated 10-year cardiovascular disease risk is more than 10%. It may make more sense to first focus on other risk-reducing steps, such as smoking cessation, blood pressure control, and statin treatment. After that, prophylactic aspirin may be reasonable for people who retain a 10-year cardiovascular disease risk of more than 10% who are also not at increased bleeding risk. That seems to make it prudent to avoid aspirin for primary prevention once people reach the age of 70 years, although people who have been taking aspirin safely for a period of time before reaching 70 might reasonably consider continuing the prophylaxis for a period of time.

This and similar reviews continue to have major limitations. The duration of the trials they reviewed, a mean of 6.4 years, is insufficient to understand the full effect from aspirin prophylaxis. Also, none of the recent reviews used a patient-level meta-analysis, which could better help us understand aspirin’s action in key subgroups, such as women, patients with diabetes, and patients on treatments such as statins that reduce their cardiovascular risk.

How to reverse type 2 diabetes with a crash diet: the DiRECT approach

A new approach
Article Type
Changed

Seventy-percent of type 2 diabetes patients who lost more than 33 pounds on a liquid diet over a few months, and kept it off, were free of the disease at 2 years, according to United Kingdom investigators.

M. Alexander Otto/MDedge News
Dr. Roy Taylor

The odds of remission – meaning a hemoglobin A1c below 6.5% on repeat testing, off all medications – were directly related to the amount of weight patients lost; 60% of subjects who lost 22-33 pounds were free of type 2 disease at 2 years, versus 29% who lost 11-21 pounds, and 5% who lost less than 11 pounds.

“If people lose” around 30 pounds “and keep it off for 2 years, there’s a two-thirds chance of them escaping type 2 [diabetes]. People want to understand their options, and this is an option. This is very good news for people with diabetes,” said senior investigator Roy Taylor, MD, a professor of medicine and metabolism at the University of Newcastle, Newcastle upon Tyne, England, who presented the findings of the Diabetes Remission Clinical Trial (DiRECT) at the annual scientific sessions of the American Diabetes Association (Lancet Diabetes Endocrinol. 2019 May;7(5):344-355).

A subgroup analysis he also presented found that beta cell function rebounds rapidly after weight loss and is pretty much normal at 2 years, so long as people keep the weight off.


The study is rooted in previous work by Dr. Taylor and his colleagues that found that very low-calorie diets normalized fasting plasma glucose in just 7 days in patients with type 2 diabetes due to a rapid fall in liver fat content and subsequent restoration of insulin sensitivity. That and other findings suggested that fast weight loss – instead of the traditional gradual approach – might help.

He and his team randomized 149 volunteers from primary care practices in the United Kingdom to standard care, and 149 others to rapid weight loss; more than a quarter of the patients who were asked agreed to participate.

 

 


Patients had diabetes for less than 6 years and were not insulin dependent. The baseline mean body mass index was 35 kg/m2, mean age 54 years, mean hemoglobin A1c 7.6%, and mean duration of disease 3 years; 176 subjects were men.

Diabetes drugs, anti-hypertensives, and diuretics were stopped in the weight loss group; the program consisted of three Optifast meal replacement shakes or soups per day – Optifast is one of many commercially available options – for a daily intake of 825-853 kcal. There was no other food, and alcohol was not permitted. The weight loss goal was 33 pounds or more over 3-5 months; almost 90% of the intervention group made it. The protocol did not include exercise.

Next came a 2-8 week stepped reintroduction to normal food, followed by counseling and other supportive care out to 2 years, plus some extra packets of Optifast, just in case.

“People [had] panic attacks when they [went] back into the kitchen, but that’s marvelous: we [had] a blank slate on which to write new dietary habits, building up knowledge of portion size and what to eat.” Dr. Taylor said.

At 1 year, 68 (46%) of the intervention participants were in remission off all drugs, and 36 (24%) had maintained at least a 33-pound weight loss. At 2 years, 53 (36%) were in remission, and 17 (11%) had maintained. Percent remission was linked to the extent of sustained weight loss.

Strokes, heart attacks, and other serious adverse outcomes were less common in the diet group, versus standard care, at both 1 and 2 years.

Among those who went into remission, the rapid initial response to a glucose bolus came back to near normal soon after food reintroduction, and “was sufficient to get nondiabetic blood glucose control,” with a mean hemoglobin A1c of 6% at 2 years. “We [also] saw, quite remarkably, was a slow steady return to almost completely normal” maximum beta cell capacity over the first 12 months, Dr. Taylor said.

The most likely explanation is that beta cells are overwhelmed and shut down in a milieu of too much fat and glucose, but are able to reconstitute their specialist function and come back online once it’s addressed, he added.

The study was funded by Diabetes UK. Dr. Taylor reported financial relationships with Self, Wilmington Healthcare, Lilly Diabetes, and Novartis AG.

This study really proposes a new approach to people who have recent-onset type 2 diabetes. Our current approach is to recommend reduced caloric intake, exercise, and medication.

This study really proposes a new approach to people who have recent-onset type 2 diabetes. Our current approach is to recommend reduced caloric intake, exercise, and medication. It’s usually viewed as a progressive disease, with some individuals eventually requiring insulin. These remarkable results were obtained in the real world of clinical practice, not in a research study.

A new approach

Seventy-percent of type 2 diabetes patients who lost more than 33 pounds on a liquid diet over a few months, and kept it off, were free of the disease at 2 years, according to United Kingdom investigators.

The odds of remission – meaning a hemoglobin A1c below 6.5% on repeat testing, off all medications – were directly related to the amount of weight patients lost; 60% of subjects who lost 22-33 pounds were free of type 2 disease at 2 years, versus 29% who lost 11-21 pounds, and 5% who lost less than 11 pounds.

“If people lose” around 30 pounds “and keep it off for 2 years, there’s a two-thirds chance of them escaping type 2 [diabetes]. People want to understand their options, and this is an option. This is very good news for people with diabetes,” said senior investigator Roy Taylor, MD, a professor of medicine and metabolism at the University of Newcastle, Newcastle upon Tyne, England, who presented the findings of the Diabetes Remission Clinical Trial (DiRECT) at the annual scientific sessions of the American Diabetes Association (Lancet Diabetes Endocrinol. 2019 May;7(5):344-355).

A subgroup analysis he also presented found that beta cell function rebounds rapidly after weight loss and is pretty much normal at 2 years, so long as people keep the weight off.


The study is rooted in previous work by Dr. Taylor and his colleagues that found that very low-calorie diets normalized fasting plasma glucose in just 7 days in patients with type 2 diabetes due to a rapid fall in liver fat content and subsequent restoration of insulin sensitivity. That and other findings suggested that fast weight loss – instead of the traditional gradual approach – might help.

He and his team randomized 149 volunteers from primary care practices in the United Kingdom to standard care, and 149 others to rapid weight loss; more than a quarter of the patients who were asked agreed to participate.

 

 


Patients had diabetes for less than 6 years and were not insulin dependent. The baseline mean body mass index was 35 kg/m2, mean age 54 years, mean hemoglobin A1c 7.6%, and mean duration of disease 3 years; 176 subjects were men.

Diabetes drugs, anti-hypertensives, and diuretics were stopped in the weight loss group; the program consisted of three Optifast meal replacement shakes or soups per day – Optifast is one of many commercially available options – for a daily intake of 825-853 kcal. There was no other food, and alcohol was not permitted. The weight loss goal was 33 pounds or more over 3-5 months; almost 90% of the intervention group made it. The protocol did not include exercise.

Next came a 2-8 week stepped reintroduction to normal food, followed by counseling and other supportive care out to 2 years, plus some extra packets of Optifast, just in case.

“People [had] panic attacks when they [went] back into the kitchen, but that’s marvelous: we [had] a blank slate on which to write new dietary habits, building up knowledge of portion size and what to eat.” Dr. Taylor said.

At 1 year, 68 (46%) of the intervention participants were in remission off all drugs, and 36 (24%) had maintained at least a 33-pound weight loss. At 2 years, 53 (36%) were in remission, and 17 (11%) had maintained. Percent remission was linked to the extent of sustained weight loss.

Strokes, heart attacks, and other serious adverse outcomes were less common in the diet group, versus standard care, at both 1 and 2 years.

Among those who went into remission, the rapid initial response to a glucose bolus came back to near normal soon after food reintroduction, and “was sufficient to get nondiabetic blood glucose control,” with a mean hemoglobin A1c of 6% at 2 years. “We [also] saw, quite remarkably, was a slow steady return to almost completely normal” maximum beta cell capacity over the first 12 months, Dr. Taylor said.

The most likely explanation is that beta cells are overwhelmed and shut down in a milieu of too much fat and glucose, but are able to reconstitute their specialist function and come back online once it’s addressed, he added.

The study was funded by Diabetes UK. Dr. Taylor reported financial relationships with Self, Wilmington Healthcare, Lilly Diabetes, and Novartis AG.

Carotid ultrasound may aid cardiovascular risk stratification of patients with psoriatic disease

Article Type
Changed

 

Subclinical atherosclerosis in the carotid arteries as measured by ultrasound appears to nearly triple the risk of a first cardiovascular event among patients with psoriatic disease, according to findings from a retrospective study.

pixologicstudio/Thinkstock.com

When added to the Framingham risk score, the measurement significantly improved its predictive ability, Curtis Sobchak, MD, and colleagues wrote in Arthritis & Rheumatology.

The findings indicate that carotid ultrasound could be a useful addition to cardiovascular risk stratification among these patients.

“Traditional algorithms do not consider other factors that may contribute to increased cardiovascular risk in rheumatic disease patients and tend to underestimate cardiovascular risk,” wrote Dr. Sobchak of the University of Toronto and coauthors.

“The advantage of ultrasound over other modalities for vascular imaging includes lack of radiation, low cost of the examination, and its widespread use in rheumatology for joint evaluation. Thus, this assessment could potentially be performed ‘at the bedside’ during consultation to provide immediate valuable information to complement clinical data from history, physical examination, and laboratory data,” they added.

The study retrospectively examined a prospective, observational cohort of 559 patients with psoriasis alone or psoriasis and psoriatic arthritis enrolled in the University of Toronto Psoriatic Disease Program. The investigators evaluated five ultrasound measures of atherosclerosis, including total plaque area (TPA), mean carotid intima-media thickness (cIMT), maximal cIMT, plaque category, and TPA category. Then they analyzed the risk relationship with major cardiovascular events (CVEs) classified as myocardial infarction, unstable angina, ischemic stroke, revascularization procedures, or cardiovascular-related death. Minor CVEs included stable angina, exacerbation of congestive heart failure, and transient ischemic attack over a mean follow-up close to 4 years.

The mean baseline TPA was 0.18 cm2 and mean cIMT was 639 mcm. Most patients had plaques, including 27.0% with unilateral and 31.5% with bilateral plaques.

The rate of a first CVE during the study period was 1.11 per 100 patient-years, and the rate of a first major CVE was 0.91 per 100 patient-years. The risk of each was significantly related to a higher baseline burden of atherosclerosis.



A multivariate analysis determined that increased TPA at baseline increased the risk of an event by nearly 200% (hazard ratio, 2.85). Mean cIMT was not an independent predictor in the final analysis, “suggesting that TPA is a stronger predictor for CVE than cIMT,” the authors wrote.

Finally, they examined the predictive value of atherosclerosis alone, as well as combined with the Framingham risk score. The 5-year model indicated that the bivariate model was slightly more accurate than the Framingham score alone (area under the curve, 0.84 vs. 0.81), although this was not a significant difference. The predictive value of the Framingham risk score plus maximal cIMT, mean cIMT, or TPA all significantly improved when they were calculated using only high-risk patients (those above the treatment threshold for dyslipidemia).

“To the best of our knowledge this is the first study to assess the utility of various measures of carotid atherosclerosis to predict CVE in patients with psoriasis and PsA [psoriatic arthritis]. ... Combining vascular imaging data with clinical and laboratory measures of traditional cardiovascular risk factors could improve accuracy of cardiovascular risk stratification in patients with psoriatic disease and facilitate earlier initiation of appropriate treatment to reduce CVE in this population,” the investigators wrote.

The study was supported in part by a Young Investigator Operating Grant from the Arthritis Society. Dr. Sobchak had no financial disclosures.

Lipoprotein(a) levels can guide CV risk assessment and treatment

Article Type
Changed

 

Lipoprotein(a) is an independent risk factor for atherosclerotic cardiovascular disease–related events, and plasma levels of Lp(a) could help refine risk assessment and influence treatment decisions, say the authors of a scientific statement from the National Lipid Association.

Don P. Wilson, MD, of Cook Children’s Medical Center, Fort Worth, Tex., and coauthors reviewed the evidence around testing of Lp(a) in clinical practice and its use in guiding treatment for both primary and secondary prevention. Their report is in the Journal of Clinical Lipidology.

Prospective, population-based studies point to a clear link between high Lp(a) levels and high risk of myocardial infarction, coronary heart disease, coronary artery stenosis, carotid stenosis, valvular aortic stenosis, ischemic stroke, cardiovascular mortality, and all-cause mortality, the authors wrote. This association was independent of the effect of other risk factors, including LDL cholesterol.

However, existing Lp(a) assays have not been globally standardized, and there is only incomplete evidence for age, sex, or ethnicity-specific cutoff points for high risk.

The authors suggested Lp(a) levels greater than 50 mg/dL (100 nmol/L) could be considered a risk factor that justifies the initiation of statin therapy. However ,they pointed out this level corresponded to the 80th population percentile in predominantly white populations, while in African American populations the equivalent cutoff was around 150 nmol/L.



On the issue of whom to test for Lp(a) serum levels, the authors said testing could reasonably be used to refine risk assessment for atherosclerotic cardiovascular disease in adults with first-degree relatives who experienced premature atherosclerotic cardiovascular disease, those with a personal history of the disease, or in those with severe hypercholesterolemia or suspected familial hypercholesterolemia.

However, statin therapy does not decrease Lp(a) levels, and there is also evidence that patients with high Lp(a) levels may not show as much LDL-C lowering in response to statin therapy.

“There is a lack of current evidence demonstrating that lowering Lp(a), independently of LDL-C, reduces ASCVD events in individuals with established ASCVD,” the authors wrote. “It appears that large absolute reductions in Lp(a) may be needed to demonstrate a significant clinical benefit.”

Despite this, the authors argued that in primary prevention, it was reasonable to use a Lp(a) level greater than 50 mg/dL (100 nmol/L) as a “risk-enhancing factor,” and in high-risk or very-high-risk patients with elevated LDL-C, it could prompt use of more intensive therapies.

Five authors disclosed honorarium or advisory board positions with the pharmaceutical sector. No other conflicts of interest were declared.

FDA grants Priority Review to Vascepa for cardiovascular risk reduction

Article Type
Changed

 

The Food and Drug Administration has granted a Priority Review to the supplemental new drug application for icosapent ethyl (Vascepa).

Wikimedia Commons/FitzColinGerald/Creative Commons License

If approved, Vascepa – which is produced by Amarin – would be the first drug indicated to reduce residual cardiovascular risk in patients with LDL cholesterol managed by statins who still have persistent elevated triglycerides. The drug is now approved for reducing triglyceride levels in patients with baseline values of 500 mg/dL or greater.

The Priority Review is based on results of REDUCE-IT, a landmark cardiovascular outcomes trial whose primary results were presented at the American Heart Association scientific sessions last November and published in the New England Journal of Medicine. Vascepa achieved the primary study endpoint, reducing the relative risk for the first occurrence of a major adverse cardiovascular event significantly, by 25%.

The drug also met the study’s key secondary endpoint, reducing the incidence of a composite of cardiovascular death, nonfatal heart attack, and nonfatal stroke by 26%. Significant adverse events associated with Vascepa in the trial were peripheral edema, constipation, and atrial fibrillation.



Vascepa is currently indicated as an adjunct to diet to reduce triglyceride in adults with severe hypertriglyceridemia, a significantly smaller population than that represented in REDUCE-IT.

“We expect earlier approval of an expanded indication for Vascepa to lead to faster improvements in care for millions of patients with residual cardiovascular risk after statin therapy,” John F. Thero, president and CEO of Amarin, said in the statement.

The FDA is expected to issue a complete response by the end of September. Find the full press release on the Amarin website.

“We expect earlier approval of an expanded indication for Vascepa to lead to faster improvements in care for millions of patients with residual cardiovascular risk after statin therapy,” John F. Thero, president and CEO of Amarin, said in the statement.

The FDA is expected to issue a complete response by the end of September. Find the full press release on the Amarin website.

If approved, Vascepa – which is produced by Amarin – would be the first drug indicated to reduce residual cardiovascular risk in patients with LDL cholesterol managed by statins who still have persistent elevated triglycerides. The drug is now approved for reducing triglyceride levels in patients with baseline values of 500 mg/dL or greater.

The Priority Review is based on results of REDUCE-IT, a landmark cardiovascular outcomes trial whose primary results were presented at the American Heart Association scientific sessions last November and published in the New England Journal of Medicine. Vascepa achieved the primary study endpoint, reducing the relative risk for the first occurrence of a major adverse cardiovascular event significantly, by 25%.

The drug also met the study’s key secondary endpoint, reducing the incidence of a composite of cardiovascular death, nonfatal heart attack, and nonfatal stroke by 26%. Significant adverse events associated with Vascepa in the trial were peripheral edema, constipation, and atrial fibrillation.
