New Dem Health Panel Chair Took More Pharma Money Than Any Other Rep


The Democratic rep who will lead the Energy and Commerce Subcommittee on Health in the new session of Congress has taken more money from the pharmaceuticals and health products industry over her career than any other member of the House.
Rep. Anna Eshoo of California’s 18th Congressional District will chair the subcommittee after accepting more than $1.6 million in campaign contributions from PACs and individuals affiliated with pharmaceutical and health products companies over the course of her career, according to data compiled by the Center for Responsive Politics. In the 2018 election cycle, Eshoo received $153,450 from the industry, including contributions from the PACs of AbbVie, BioMarin pharmaceuticals, Bristol-Myers Squibb, Pfizer, Merck, and many other drug companies.
The Energy and Commerce Health Subcommittee has jurisdiction over the regulation of the drug industry, among other things. While many Democrats, and even some Republicans, including President Trump, have been advocating action to address the rapid increase in the prices of some drugs, Eshoo has taken a softer tone.
“I’m going to be fair. I’m not out to punish or to do things out of vengeance,” she said when asked by reporters recently if she would be tough on drug companies in her role at the helm of the health subcommittee.
Eshoo has a record of working to advance legislation that benefits the pharmaceuticals industry. In 2009, she introduced legislation, along with Texas Republican Joe Barton, to give pharmaceutical companies 12-year exclusivity periods for biologic drugs, beyond the length of their patents, to protect them from competition by the generic drug industry. Biologics are a class of drugs that target the genetic source of diseases such as multiple sclerosis, rheumatoid arthritis, and Crohn’s disease. Standard chemical drugs get exclusivity periods of five years.
The Eshoo-Barton bill, which was supported by the Biotechnology Industry Organization, a trade group that lobbies the government on behalf of hundreds of biotechnology and pharmaceuticals companies, was passed into law as part of the Affordable Care Act, despite opposition from President Obama and many of her Democratic colleagues.
Following the enactment of the Eshoo-Barton bill, the Biotechnology Industry Organization named Eshoo “legislator of the year” in 2010. The organization had previously given Eshoo the honor in 2002.
Eshoo has also sponsored pharmaceuticals industry-backed legislation to protect a program under which drug companies pay fees to the Food and Drug Administration (FDA) to help speed up the drug approval process. This program has been criticized as a source of regulatory capture by watchdog groups like the Project on Government Oversight. “This arrangement gives the pharmaceutical industry extraordinary influence over its government overseer,” POGO wrote in a 2016 report. “It leaves the regulator beholden to the regulated.”
When it comes to bills that address the issue of rising drug prices, Eshoo has not been a supporter. The most prominent of such bills is the Fair Accountability and Innovative Research Drug Pricing Act (H.R. 2439), a 2017 bipartisan measure that would require drug companies to provide notice and justification for price increases that result in a 10 percent or more increase in the cost of a drug over a 12-month period or a 25 percent or more increase over a 36-month period. The bill had 25 co-sponsors in the 115th Congress, but Eshoo was not one of them.
And on Medicare for All, which would likely reduce drug prices because of the immense buying power the government would yield, Eshoo recently backed away from her own suggestion that the subcommittee might hold a hearing on the policy. On Jan. 17 she changed her tune and told Politico that it was unlikely the committee would be able to find “spare time” to discuss Medicare for All.
In response to an August 2018 campaign ad criticizing her record on drug prices, Eshoo’s campaign issued a statement noting that the Representative “supports price negotiations in Medicare Part D to drive down costs,” a policy change that President Trump also favors and partially accomplished in a November 2018 rule proposal.
Eshoo’s bid to lead to the Health Subcommittee received critical early supportfrom Rep. Frank Pallone (D-N.J.), the Chairman of the Energy and Commerce Committee. Pallone also counts the pharmaceuticals and health products industry among his top donors, having pulled in $252,450 from PACs and individuals in the industry in the 2018 election cycle, according to the Center for Responsive Politics.

7 biopharma trends to watch in 2019


Bristol-Myers Squibb’s splashy $74 billion Celgene buy is set to reset the top ranks of pharma, but the industry’s year ahead will be shaped more directly by larger trends impacting the sector’s perception, investment and future growth.
Public criticism and scrutiny from lawmakers will likely remain, keeping biotech and pharma under pressure. At the same time, a cooperative FDA and scientific advances in oncology, cell and gene therapy should continue to serve as a tailwind, generating new approvals and investor optimism.
Digital opportunities, including in artificial intelligence, have also proved attractive to drugmakers, spurring changes among executive teams.
Here are seven trends to watch as 2019 unfolds:

Political pressure on drugmakers rises

Among Elijah Cummings’ first acts as chairman of the House Oversight Committee was announcement of a broad investigation into prescription drug prices.
After two weeks as head of the powerful committee with broad subpoena powers, the Maryland Democrat has made clear rising pharmaceutical costs will be an early target. That attention, and House Democrats’ focus on healthcare in their retaking of the House of Representatives, are among the signs that political pressure on drugmakers could ramp up over the next two years.
Congress has periodically put the industry’s pricing practices at the center of its scrutiny in years past. But that spotlight will likely be fixed more permanently under Democratic control of the House.
Making that attention more dangerous for pharma is the Trump administration’s actions to push forward policies anathema to drugmakers. Plans to require list prices in television ads and link Medicare payments to what’s paid abroad remain in early stages, but criticism of the industry has flowed freely from the Republican White House.
Democrats may be reluctant to hand the president a major domestic policy win on drug pricing. But that doesn’t rule out some bipartisan cooperation, potentially resulting in tangible policy losses for an industry used to wielding its political clout.
“We are willing to work with Democrats and Republicans to accomplish what was set forth in @POTUS’s drug pricing blueprint—lower list prices and reduced out-of-pocket costs for Americans,” Health and Human Services Secretary Alex Azar wrote in a Jan. 15 tweet.

Price hikes remain, but companies become more selective

Jan. 1 brought fresh price increases on dozens of major drugs, marking a return to what Pfizer CEO Ian Read last year termed “business as normal.”
Upping prices at the start of a new year is standard practice for the industry. This year, however, was a test of how drugmakers would proceed after a confrontation between President Donald Trump and Pfizer led many to announce price freezes or temporary roll-backs of previous price hikes.
Unsurprisingly, drugmakers were largely undeterred, with many moving ahead with increases ranging between low- to mid-single digits. While seemingly a provocative move, the underlying rationale is clear: biotech and pharma companies depend on price increases for revenue growth, particularly for older products.
Investment bank Raymond James did, however, track fewer hikes in the key Dec. 1 to Jan. 1 period than it did in 2017, suggesting pharma companies are becoming more selective in which drugs they take increases on.
That idea is borne out by moves from Pfizer, Merck & Co., Eli Lilly and Biogen. Price increases taken by each were largely kept to products crucial to future growth, or limited to a select basket of products.
Merck, for example, in November increased the prices of its top-selling cancer drug Keytruda and its vaccine Gardasil, along with three other products. In announcing late last year price increases for 41 drugs, Pfizer emphasized that for about 90% of its product portfolio, prices would remain the same.
Such an approach could reflect pharma efforts to walk a fine line between limiting their exposure to criticism, while retaining pricing as a lever to pull for higher revenue and profit.
“We suspect many of these firms are simply taking more of a wait-and-see approach, with a greater number of increases anticipated in the weeks ahead,” wrote Raymond James analyst Elliot Wilbur in a Jan. 1 note to investors.

Oncology remains a top draw for biopharma

In recent years, pharmaceutical companies have consistently prioritized investment into cancer drug development, making for an industry-wide turn toward oncology.
Ninety billion dollars in cancer-focused dealmaking between December and the opening weeks of 2019 show that emphasis hasn’t waned.
Uniting deals by Bristol-Myers SquibbEli Lilly and GlaxoSmithKline is a shared desire to deepen cancer drug pipelines and strengthen commercial presence in what has become the industry’s hottest field.
AstraZeneca, Gilead Sciences, Regeneron and Sanofi, meanwhile, have all made a concerted effort in the space than in the past.
Scientific and clinical advances have catalyzed drug development, but so too has a cooperative regulator and a market accepting of price tags stretching past $100,000 per year.
Those tailwinds look likely to persist in 2019.
Companies remain eager to invest, even as competition increases and pipelines swell. The FDA, meanwhile, waved through 17 cancer drugs last year — adding to a five-year total of nearly 60 new treatments.
And while cancer drug prices have faced scrutiny, criticism to date has fallen most heavily on drugs in other therapeutic areas. Payers, meanwhile, appear generally willing to cover newly approved therapies.

FDA keeps pace of approvals high — presuming shutdown doesn’t linger

The Food and Drug Administration set a record last year for the number of new drugs approved, greenlighting 59 novel therapies — well above the regulator’s 10-year average of 33 per year.
That rising tempo looks likely to continue in 2019, provided a government shutdown that’s hampered the agency doesn’t continue for much longer.
Part of that upward trajectory is due to the increasing use of expedited development and review pathways by FDA. Last year, 41% of OK’d medicines were granted Fast Track status, while 73% had Priority Review tags. (Some medicines were approved via Priority Review due to a sponsor using a special regulatory voucher.)
Surging investment in cancer and rare disease research is likely helping as well, since many medicines in either field are able to reach regulators with smaller datasets and genetically defined patient populations.
As long as the government shutdown continues, however, the FDA is unable to accept new drug applications and user fees. The agency has been able to continue work on applications already submitted, but an enduring lapse in funding could have a large impact on the number of new medicines reaching patients in 2019.

Rise of the pharma chief digital officer

This month, Albert Bourla took over the reins as CEO of Pfizer, bringing with him several changes to the leadership of America’s largest pharmaceutical company.
Among them is the appointment of Lidia Fonseca as the company’s first chief digital and technology officer. In announcing the role, Pfizer offered few details beyond noting Fonseca would help create a strategy that helps improve the drugmaker’s “digital capabilities.”
Fonseca joins a growing group of chief digital officers in the ranks of pharma executive committees.
Last October, Merck & Co. appointed a former Nike executive as the company’s chief information and digital officer, expanding the role and elevating it for the first time to rank on the executive committee. The year before, GlaxoSmithKline, Novartis and Eli Lilly all added similar positions to their respective executive committees, signaling a growing emphasis pharma on upgrading digital infrastructure.
The industry’s largely operated behind the curve in its adoption and use of digital technologies like artificial intelligence. Expectations, though, are high that such tools could help raise productivity in drug development, or help manage increasingly complex clinical trials.
“In every area — from where we innovate and find new medicines to how we operate, how we think about manufacturing and supply chain to how our sales reps do their work every single day — we are working on major projects to scale our digital capabilities,” said Novartis CEO Vas Narasimhan to a room full of investors as the J.P. Morgan Healthcare Conference earlier this month.
Chief digital officers aren’t yet omnipresent in pharma boardrooms, with many companies going without or keeping the role at a senior vice president level. Pfizer and Merck, though, make for powerful examples.

Biosimilars begin to bite in the U.S.

This year could prove a major test of how well biosimilars can live up to the lofty expectations surrounding the copycat biologic drugs.
To date, biosimilars have had little impact in the U.S., posting modest sales and price discounts to their branded counterparts that fall well short of generic levels.
Some signs, however, suggest that could begin to shift.
Seven of the 16 approved biosimilars in the U.S. garnered FDA OKs last year and the agency appears ready to add rapidly to that total. A recent tweet by FDA Commissioner Scott Gottlieb, for example, noted 70 currently ongoing biosimilar development programs.
More biosimilars are launching as well, with copies from Pfizer, Mylan and Coherus BioSciences reaching patients over the past 12 months. Roche expects a copy of its cancer drug Rituxan to become available earlier this year, while key patents for its other top biologic Herceptin expire this year in the U.S.
Three branded drugs — Neulasta, J&J’s Remicade and Amgen’s Neupogen — now face two biosimilar competitors. FDA research on generic marketshas shown discounts begin to climb as more copies enter, suggesting the hoped-for savings from biosimilars will come only as more are approved and launched.
Still, the impact on prices and spending on biologic drugs will likely remain small relative to Europe, where the copycat drugs have been available for longer. Stronger patent defenses and exclusionary contracting with insurers have proved tall hurdles to climb, and will continue to pose challenges.

Ecosystem supporting cell and gene therapy grows

Approval of Spark Therapeutics’ Luxturna in late 2017 marked the first time a gene therapy for an inherited disorder was cleared for commercial use in the U.S.
By 2025, the FDA predicts it will be approving between 10 and 20 cell or gene therapy products each year.
That expected boom reflects the significant progress of the science surrounding the use of genetic tools to construct new therapeutics. Delivery platforms like adeno-associated viruses help enable the replacement of defective genes, while technologies such as CRISPR/cas9 hold the promise of direct genetic editing.
All of this makes for what the FDA calls a “turning point” in the field, one akin to the turn toward monoclonal antibodies in the 1990s.
Just as investment in monoclonal antibody research spurred a surge in biologic drug manufacturing, gene therapy advances have led to rapid build-out of support services.
Contract manufacturers as well as drugmakers have invested in expanding production capacity for both cell and gene therapies. Swiss giant Lonza, for instance, last spring opened a sprawling, 300,000-square-foot facility that it says is the world’s largest dedicated to production of the complex treatments.
Also enjoying the field’s expansion are suppliers of viral vectors and plasmids as well as cold chain shippers like Cryoport.
For biotechs like Sarepta, the growth in contractors capable in gene therapy enables a hybrid model mixing internal capabilities with external support — a model Sarepta argues enables it to move faster.
“Manufacturing for gene therapy is going to be the significant rate-limiting step for folks who are really interested,” said Sarepta CEO Doug Ingram in a recent interview. “We are committing hundreds of millions of dollars to ensure that we are getting manufacturing correct.”

Aspirin for Primary Prevention


A new meta-analysis of trials evaluating aspirin for primary prevention of cardiovascular disease has found no overall benefit, with aspirin use associated with a lower risk of cardiovascular events but an increased risk of major bleeding, and no effect of aspirin on cancer risk.
However, there still appears to be some disagreement on how to apply these findings.
“A review of the evidence for use of aspirin in primary prevention was last looked at 5 or 6 years ago but now we have additional data from three new trials published last year — ARRIVE in people at higher CV risk, ASCEND in people with diabetes, and ASPREE in older individuals,” lead author of the new meta-analysis, Sean Zheng, BM, BCh, King’s College Hospital, London, United Kingdom, told Medscape Medical News.
“This new analysis was done to bring together the total evidence on aspirin in primary prevention of cardiovascular disease now available in a mixed population,” he said.
“We found that aspirin did reduce cardiovascular events by a modest 11%, with a number needed to treat to prevent one event of 265, but it also increased major bleeding, such as serious GI bleed, intracranial bleed or bleed needing hospitalization or transfusion by 43%. That is a number needed to harm of 210,” Zheng reported.
“These numbers needed to treat for benefit and harm are of similar magnitude,” he said. “So there isn’t a clear-cut benefit, and in order to make a decision each patient would have to be considered individually with their own personal view of how they value these benefits and risks. But at the population level, we can say this is not strong enough evidence to recommend use of aspirin routinely.”
The meta-analysis was published online in JAMA yesterday.
Zheng explained that the earlier trials of aspirin for primary prevention tended to include all levels of cardiovascular risk — true population studies — but as these did not show a clear benefit, the later trials have tried to select out higher risk groups.
“But the results are similar across the board — aspirin appears to reduce cardiovascular events but increases bleeding to a similar degree in all groups,” he said. “We can never disengage the benefit from the risk.”

Guidelines Not Consistent

What effect will this latest meta-analysis have on guidelines? Zheng noted that UK and European guidelines generally do not recommend aspirin for primary prevention, but some of the US guidelines still recommend it based on age or cardiovascular risk, and there are a large number of patients in the US still taking aspirin for primary prevention.
“I think the US guidelines should change to not routinely recommending aspirin in primary prevention for any group, and our data should help in that regard,” he said.
In an accompanying editorial, however, Michael Gaziano, MD, Brigham and Women’s Hospital, Boston, Massachusetts, says this is not so clear-cut, pointing out that the cancer benefit of aspirin is not seen until much longer follow-up — and suggesting that there may still be a role for aspirin in some patients for primary prevention.
The new meta-analysis included a total of 13 trials randomizing 164,225 participants with a total of 1,050,511 participant-years of follow-up.
The median age of trial participants was 62 years (range 53-74), 47% were men, 19% had diabetes, and the median baseline risk of the primary cardiovascular outcome (cardiovascular mortality, nonfatal MI and nonfatal stroke) was 9.2% (range 2.6%-15.9%).
Aspirin use was associated with significant reductions in the composite cardiovascular outcome: 57.1 per 10,000 participant-years with aspirin vs 61.4 with no aspirin (hazard ratio [HR] 0.89; number needed to treat 265).
Aspirin use was also associated with an increased risk of major bleeding events, 23.1 per 10,000 participant-years with aspirin vs 16.4 with no aspirin (HR 1.43; number needed to harm, 210).
Aspirin use was associated with reductions in the primary cardiovascular composite outcome and increases in major bleeding risks in both low and high cardiovascular risk populations and in participants with diabetes.
“Compared with aspirin use in patients with established atherosclerotic cardiovascular disease, aspirin use for primary prevention has been controversial,” Zheng and colleagues write. “This uncertainty has been reflected in contradictory guideline recommendations. The current study demonstrates that when considering the totality of evidence, cardiovascular benefits associated with aspirin were modest and equally balanced by major bleeding events.”
They note that co-prescription of aspirin with a proton pump inhibitor (PPI) may limit the risk of significant gastrointestinal bleeding and, therefore, shift the risk-benefit ratio toward an overall benefit of aspirin use for primary prevention; however, the use of PPIs was inconsistently reported in the studies included in this analysis. Furthermore, this strategy has not been adequately tested in randomized trials and is of uncertain cost effectiveness, they add.

No Effect on Cancer Risk?

Another interesting finding from the meta-analysis was a neutral effect of aspirin on cancer — both cancer death and new cancer diagnosis. “From our data there doesn’t appear to be any benefit of aspirin on cancer risk,” Zheng said.
However, in his editorial, Gaziano says the finding of no overall association between aspirin use and incident cancer or cancer mortality is “consistent with previous studies that did not detect an effect of aspirin on reduction in risk of total cancer until much longer follow-up.”
Gaziano describes the new meta-analysis as “well conducted,” and says it shows that the best estimates for the effects of aspirin on cardiovascular events and bleeding have not materially changed after the results of the three new trials published in 2018.
He notes that the similarity of the number needed to treat and the number needed to harm has been the rationale for some guidelines that recommend not using aspirin for primary prevention but rather waiting to initiate aspirin until there is manifest cardiovascular disease (secondary prevention), when the separation between benefit and risk is clearer.
On the other hand, Gaziano points out that the US Preventive Services Task Force (USPSTF) takes into consideration the longer-term potential effects of aspirin in reducing the risk of colorectal cancer, and recommends aspirin for primary prevention based on a patient’s risk of future vascular disease, bleeding events, and longevity, as well as personal preferences.
This new meta-analysis “demonstrates that the estimates for aspirin preventing vascular events and for increasing bleeding risk that support this USPSTF approach are largely unchanged after the addition of the new trials,” Gaziano states.
He cautions, however, that assessing cardiovascular risk is complicated, with risk calculators tending to overestimate risk for populations in which risk is declining, such as in the United States and Europe. In addition, risk will change if patients change their lifestyles, and when applying these results to an individual patient, clinicians must consider other interventions such as smoking cessation and control of blood pressure and lipid levels, to lower risk.
“In places of the world in which cardiovascular risk is rising or where other preventive strategies, such as statins, are less available, aspirin as a low-cost intervention may have a more important role,” he writes.
“Aspirin remains an important medication for acute management of vascular events; for use after certain procedures; for secondary prevention; and, after careful selection of the right patients, for primary prevention,” Gaziano concludes.
The authors of the meta-analysis have disclosed no relevant financial relationships. Gaziano reports serving on the executive committee of the ARRIVE trial and serving as a consultant and receiving honoraria for speaking for Bayer.

Key protein in insulin production discovered


The crucial hormone insulin needs help acquiring the right structure. A protein that assists in the process of insulin folding has just been discovered in a new study conducted by researchers at the Department of Biomedical Sciences, University of Copenhagen. They hope the new research results can be used to develop treatments for conditions such as increased level of insulin in the blood known as hyperinsulinemia.
Even though researchers have been familiar with and studied the hormone insulin for more than a hundred years, especially in connection with diabetes, they still make new discoveries concerning the hormone. Now researchers from the Faculty of Health and Medical Sciences at the University of Copenhagen have uncovered a hitherto unknown process in the production of insulin. The new research results have just been published in the scientific journal Diabetes.
Insulin is produced in the beta cells of the pancreas. The hormone is produced as a precursor called proinsulin. For proinsulin to mature into functional insulin, it needs to be folded and processed correctly to acquire the right structure with assistance from proteins that are termed chaperones. The researchers have now discovered and identified such a chaperone. A proinsulin chaperone termed glucose-regulated protein GRP94.
‘Even though proinsulin has a relatively short sequence, it still needs help acquiring the right structure to become mature, functional insulin. However, several other studies have shown that proinsulin can be folded without help from proteins in artificial cell-free conditions. Yet, our study conducted in live cells shows that proinsulin is not folded correctly and does not acquire the right structure without help from GRP94,’ says last author of the study, Associate Professor Michal Tomasz Marzec from the Department of Biomedical Sciences at the University of Copenhagen.

Impaired Insulin Production and Secretion

In the study the researchers removed or inhibited the protein GRP94 in to see what happened with the proinsulin and the cells. They observed that the proinsulin was not folded correctly and the beta cells did not secrete sufficient amounts of insulin. The researchers were surprised though to learn that removal of GRP94 did not affect cell viability. Nothing happened to the cells after they had removed the protein.
‘This is surprising, because one would anticipate that the beta cells would die from stress when huge amounts of misfolded proinsulin accumulate inside the cells. It is like removing the bearing beam without weakening the construction. This indicates that the GRP94 protein plays a very specialized function and that beta cells are well-prepared to mount effective responses to deal with consequences of misfolding of proinsulin. We are currently working to understand these responses and their biological and pathological consequences,’ says Associate Professor Michal Tomasz Marzec.
According to the researchers, the research results may make it possible in the future to manipulate the process from proinsulin to insulin in the body’s beta cells. If you can use medicine to inhibit the assistant protein, the result would be reduced insulin secretion. This would be useful in connection with conditions like hyperinsulinemia, where the body produces too much insulin. In the long term, they also hope the new knowledge will be useful in connection with types 1 and 2 diabetes.
‘We hope this new discovery will guide the development of novel drugs. Understanding the biological processes behind the production of insulin in the cells will enable us to modify the processes. We thus hope we will be able to inhibit overproduction of insulin as it occurs in children and adults with hyperinsulinemia. In the long term we also hope we will be able to increase the production of insulin, ease the large production burden of beta cells in connection with type 2 diabetes and to maintain their secretion function for longer without the need for insulin injections,’ says Associate Professor Michal Tomasz Marzec.

Elevated BP in Young Adults Tied to Gray Matter Shrinkage


Target Audience and Goal Statement:
Neurologists, internists, family medicine practitioners, cardiologists, and radiologists
The goal was to determine whether changes in blood pressure (BP) are related to gray matter volume changes in young adults who had not previously been diagnosed with hypertension (≥140/90 mm Hg).
Questions Addressed:
Is there an association between even modestly elevated BP with gray matter volume in young adults (ages 19 to 40) who had not previously been diagnosed with hypertension?
Study Synopsis and Perspective:
Elevated BP was tied to lower gray matter volume in young adults ages 19 t0 40, researchers found.
Gray matter volumes in adults ages 20 to 30 decreased as BP increased, with changes occurring in the same brain regions seen in previous studies of older people with hypertension, reported Arno Villringer, MD, of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and colleagues, writing in Neurology.
“Previously, brain damage related to hypertension has been assumed to result over years of BP elevation, but our study suggests that subtle decreases in the brain’s gray matter volume can be seen in young adults between 20 and 40 years of age who have never been diagnosed with hypertension, and who have BP only slightly above 120/80 mm Hg,” Villringer told MedPage Today.
“While the study shows correlational relationships between above-normal BP and lower gray matter volumes, we did not yet uncover a causal link which proves that higher BP causes the observed brain alterations,” he said.
The findings add to previous research tying BP to brain changes, noted Rafael Llinas, MD, of Johns Hopkins Bayview Medical Center in Baltimore, who was not involved with the study.
Villringer and co-authors analyzed structural 3T T1-weighted magnetic resonance imaging (MRI) scans of 423 healthy young adults (mean age of 27.7) who had not previously been diagnosed with hypertension. MRI data originated from four unpublished cross-sectional studies in Leipzig from 2010 to 2015. The researchers performed voxel-based morphometry on each study separately and combined results in image-based meta-analyses.
All participants had at least one BP reading, with the levels as follows:
  • 41% had BP lower than 120/80 mm Hg (defined as normal)
  • 29% had BP 120/80 to 129/84
  • 19% had BP between 130/85 and 139/89
  • 11% had BP above 140/90 (defined as hypertension in the study, but which is now stage II hypertension, according to U.S. guidelines).
The meta-analyses showed that, across a range of BP levels above 120/80 mm Hg, gray matter alterations emerged continuously in the hippocampus, amygdala, thalamus, frontal, and parietal structures. Differences in gray matter volume were even evident between people with BP lower than 120/80 and those with the next two levels of elevated blood pressure.
Gray matter volume differences between participants in the highest versus the lowest BP categories totaled 581 voxels (voxel size=2x2x2 mm3), with the biggest variance in the left inferior frontal gyrus (107 voxels).
The fact that associations were found in young people “suggests that BP management should be taken seriously early on and that even being ‘prehypertensive’ can have a long-term impact on the development of neurological diseases such as dementia and stroke,” noted Sun Kim, MD, of NYU Langone Hospital in New York City. “It will be interesting to see if longitudinal data can be collected and correlated with the actual development of these diseases and others.”
Villringer and co-authors concluded that the study shows that “blood pressure-associated gray matter alterations emerge continuously across the range of BP and earlier in adulthood than previously assumed.”
This suggests, the team said, that treating hypertension or maintaining lower BP in early adulthood “might be essential for preventing the pathophysiologic cascade of asymptomatic cerebrovascular disease to symptomatic end-organ damage, such as stroke or dementia.”

Study Highlights: Explanation of Findings
“As we debate whether to treat systolic BP in the 120-130 mm Hg range, a new study has found that a BP greater than 120/80 mm Hg in young adults ages 19 to 40 was associated with reduced gray matter volume not only in cortical areas — frontal, parietal, and hippocampal-temporal areas — but also in subcortical structures, the thalamus and amygdala,” observed Gayatri Devi, MD, MS, of Lenox Hill Hospital in New York City, who was also not involved in the research.
These regions are affected clinically and pathologically in neurodegenerative disorders like Alzheimer’s disease, and hypertension is a well-known risk factor for dementia, she explained. “Vascular and neurologic health are intricately intertwined and better control of hypertension as early in life as possible is one key way to reduce risk for brain disease later in life.”
Llinas told MedPage Today that there have already been papers that show that high BP reduces the grey matter in the brain and affects the deeper white matter, known risk factors for dementia in older patients. “There is evidence that your health at middle age predicts brain health as you age. But this is one of the first studies that show that changes in the brain can occur even in young age — and that hypertension may not be a disorder that harms over time, but may need to be screened for and treated much earlier than people expected,” he said.
Villringer and co-authors noted that raised midlife BP is known to be a major risk factor for vascular dementia, and some reports have suggested a link between hypertension and Alzheimer’s disease-type pathophysiology.
The researchers explained that in neuropathologic studies, elevated midlife BP has been associated with lower postmortem brain weight, increased numbers of hippocampal neurofibrillary tangles, and higher numbers of hippocampal and cortical neuritic plaques. Similar results with MRI studies show a pathophysiologic link between hypertension and Alzheimer’s disease (AD).
“In light of these previous results, our findings of lower BP gray matter volume in AD signature regions may be indicative of a link to AD pathology at an even earlier age; however, this cannot be causally inferred from our cross-sectional data,” the team wrote, adding that other studies have shown that blood pressure predicted volume loss in non-AD-typical brain regions, such as frontal lobe and subcortical gray matter.
“Contrary to assumptions that BP-related brain damage arises over years of manifest disease, our data suggest that subtle pressure-related gray matter alterations can be observed in young adults without previously diagnosed hypertension,” the researchers continued. “Considering our results, large-scale cohort studies should investigate whether subhypertensive BP and related brain changes in early adulthood increase the risk for subsequent development of cerebrovascular disease later in life.”
Understanding how the brain is globally affected by vascular change or if these are region-specific could help identify neuroimaging biomarkers for the earliest stages of cerebrovascular disease, the team stated.
Lastly, the authors noted that some previous studies did not find correlations between hypertension and lower brain volumes, but rather with other forms of structural or functional brain alterations, such as white matter injury or reduced cerebral perfusion.
The study was limited by its cross-sectional design, Villringer and colleagues noted, and it was not possible to assess causality between BP and potential brain damage. In addition, the four study samples used in the analysis differed in recruitment and data collection; in one sample, blood pressure measurements were recorded only once. Also, because the study included only gray matter measures, the mediating effects of white matter injury on gray matter volume differences could not be measured.
