Can AI Help Us Stop Missing Fatty Liver?

Artificial intelligence gets thrown around so much now that it can start to sound meaningless. Every industry is supposedly being transformed by it. A lot of that is hype.

But in fatty liver disease, AI may actually be starting to matter in more practical ways.

For years, one of the hardest things to accept in this field has been how many people with fatty liver disease are still missed until the damage is already well underway. We already know a lot about who is at risk. We know the strong links with obesity, insulin resistance, type 2 diabetes, and metabolic dysfunction. We know millions of people are affected. And we know many patients still move through the healthcare system for years without anyone taking a closer look at their liver risk.

That is why the recent growth of AI-related work in MASLD and MASH is worth paying attention to. Not because AI is some miracle solution, but because it may help with one of the biggest practical failures in this space: an overloaded healthcare system that keeps missing too many people who are right in front of it.

One place AI is starting to show up is in MASH clinical trials. A recent development in this area was the FDA qualification of an AI-assisted pathology tool designed to help make liver biopsy readings more consistent in trials. That may sound technical, but the basic idea is simple. When specialists look at biopsy slides, there can be disagreement about how much inflammation, scarring, or liver damage is really there. Those differences matter. They can affect who gets into a trial, how sick a patient is judged to be, and whether a drug appears to be helping. If AI can make those readings more consistent, it could help make trials more reliable.

“This is the first AI-powered pathology tool to receive FDA qualification through the Drug Development Tool (DDT) Biomarker Qualification Program.”

PathAI, 2026

Even more interesting, at least from a patient and public health perspective, is the possibility that AI could help with earlier diagnosis and risk stratification outside of trials.

Researchers are looking at whether AI can help identify at-risk patients using data and imaging that health systems already generate. That could mean using AI to analyze existing CT scans for signs of steatosis or fibrosis instead of letting those clues go unnoticed. It could mean automatically calculating fibrosis scores from routine lab data. It could mean flagging high-risk patients with diabetes or metabolic dysfunction in electronic health records so that liver risk is not treated like an afterthought.

“AI is also being applied to imaging, helping detect incidental fatty liver on scans performed for other reasons.”

Adam Myer, MD, via University of Cincinnati, 2026

One recent example of that showed up in a Bloomberg report about an AI model developed to help with early detection of fatty liver disease using routine CT scans. Patients are already getting scans for all kinds of reasons. If those same scans can help flag possible liver disease earlier, that could help catch at least some of the people who currently slip through the cracks.

That kind of support matters because one of the biggest problems in fatty liver disease is not simply lack of awareness. It is lack of follow-through.

People with obvious metabolic risk factors still move through primary care without anyone calculating a fibrosis score like FIB-4. Incidental fatty liver findings still get buried in radiology reports. Patients with abnormal liver enzymes still get vague advice to lose weight and come back later. Many people do not see a specialist until fibrosis is already advanced enough to become frightening. As I wrote recently, the problem is no longer just diagnosis. It is implementation.

AI may be one way to help close that gap.

There is also growing interest in whether AI-based screening approaches could make economic sense at scale. That matters because healthcare systems do not just need tools that sound promising. They need tools that can be used in the real world without overwhelming clinicians, specialists, or budgets. If AI can help identify which patients are most likely to have advanced fibrosis and need more workup, it could help create smarter referral pathways instead of simply sending every at-risk patient straight to hepatology.

“MAOSS enhanced the detection rate of high-risk cases from 16.6% to 52.4%.”

Alibaba Cloud summary of Nature Communications paper, 2026

That point matters too. I have heard hepatologists say for years that if broad screening suddenly started working perfectly and every at-risk patient got referred directly to their clinics, the system would be overwhelmed in a hurry. That is not an argument against screening. It is an argument for better triage. If AI can help health systems do a better first pass, then it may become part of a more workable solution.

There are still good reasons to be cautious. AI is already one of the most overhyped ideas in healthcare. Bad data can lead to bad recommendations. Tools that perform well in one setting may not work as well in another. Poorly designed systems could even reinforce disparities instead of reducing them. There are also real privacy concerns whenever sensitive medical data is being collected, analyzed, and shared at scale. And no algorithm is going to fix a healthcare system that is too rushed, fragmented, or inconsistent to act on the information it already has.

Still, it is not hard to imagine where this could go. Routine lab work could automatically generate liver risk alerts. CT scans done for unrelated reasons could flag steatosis or fibrosis instead of burying those findings in the fine print. Electronic medical records could identify high-risk patients with diabetes, obesity, and metabolic dysfunction before advanced liver disease develops. Clinical trials could become more consistent through better pathology tools. Over time, that could help move liver disease care away from late discovery and toward earlier detection and smarter management.

That future is not here yet. But for the first time in a while, there are signs that AI in fatty liver disease may be moving beyond buzzwords and toward something more practical.

The real test will be simple. Not whether AI sounds impressive. Not whether companies issue flashy announcements. The real test is whether it helps the healthcare system stop missing people with fatty liver disease before it is too late.

FibroScan device used for non-invasive liver stiffness testing

Fatty liver disease is common. So why are we still catching it so late?

Back in 2019, I wrote about the challenge of diagnosing NASH and the frustrating reality that tools like FibroScan, MRE, blood-based scores, and other non-invasive diagnostics were promising but still too disconnected from everyday care. At the time, the problem felt largely technological. We needed better tools, clearer answers, and a path away from relying so heavily on liver biopsy.

That is still true, but it is no longer the whole story.

Today, the more uncomfortable reality is that we do not just have a diagnostics problem. We have an implementation problem.

We already have more tools than we used to. FibroScan is no longer some exotic research device. Risk scores like FIB-4 are simple and inexpensive. Doctors know a lot more now about who is at risk. They have also spent years showing that fatty liver disease is closely tied to obesity, insulin resistance, prediabetes, type 2 diabetes, and broader metabolic dysfunction.

“This consensus report is a call to action to screen for liver fibrosis and risk stratify people with prediabetes or type 2 diabetes.”

American Diabetes Association consensus report, 2025

That is a very different mindset from the older era, when liver disease screening still felt like a side issue in routine metabolic care.

And yet far too many people are still being missed.

For years, the conversation around fatty liver disease sounded like the main problem was scientific uncertainty. We did not know enough. We did not have enough precision. We did not have enough ways to identify the right patients without putting a needle in their liver.

Now the problem looks different. It looks less like a lack of options and more like a lack of follow-through.

Patients with obvious metabolic risk factors still move through primary care without anyone calculating a fibrosis score. People with abnormal liver enzymes are still too often told to lose weight and come back later. Fatty liver findings on imaging still get buried in reports or treated like background noise. Many patients do not reach a hepatologist until fibrosis is already advanced enough to become frightening.

That is not because the medical community has no tools. It is because the tools are still not being used consistently where they matter most.

That matters because the burden is not small. The ADA consensus report notes that liver steatosis affects approximately two out of three people with type 2 diabetes. If a risk this common is still being treated like a specialty issue, then the system is not built around where the disease actually shows up.

I have heard versions of the same concern from hepatologists for years: if widespread screening suddenly started working the way it should, and every at-risk patient got referred straight to hepatology, the system would be overwhelmed almost immediately. That is not an argument against screening. It is an argument for building smarter front-line risk stratification, clearer referral pathways, and better tools in primary care so specialists are not forced to absorb the entire burden alone.

One of the biggest shifts in recent years is that fatty liver disease is finally being treated as part of the larger metabolic health crisis, not just a niche issue for hepatologists. If MASLD and MASH are closely tied to diabetes, obesity, insulin resistance, cardiovascular risk, and metabolic dysfunction, then earlier identification should be happening in the same places where those problems are already being managed.

That disconnect is dangerous because awareness without action is mostly theater. It is good to publish guidance. It is encouraging to talk about better diagnostics and treatment progress. But none of that means much for the person who is never identified in the first place.

To be fair, there are real reasons this has been hard. Primary care is overloaded. Many clinicians are juggling too many priorities. Reimbursement and workflow do not always reward deeper liver risk assessment. There is still uncertainty about exactly who should be screened, how often, and with which tools.

But those realities cannot keep serving as an excuse for inertia.

What should happen next is not mysterious. Checking liver risk needs to become a more normal part of caring for patients with metabolic dysfunction. That does not mean every primary care office suddenly becomes a liver specialty center. It does mean clinicians need practical ways to identify who needs more workup and who does not.

“More awareness about the health risks associated with MASLD and broad adoption of screening for liver fibrosis as a new standard of care hold promise for a future without cirrhosis…”

American Diabetes Association consensus report abstract, 2025

And those paths are clearer now than they used to be. Doctors now recommend starting with a simple first-line score like FIB-4, then following borderline or elevated results with a better second-line test such as liver stiffness measurement by transient elastography. The problem is not that no path exists. The problem is that it still is not routine enough.

One possible way to ease that burden is to use AI tools more intelligently in primary care. Not as a substitute for clinical judgment, and not as hype, but as a way to flag risk patterns, calculate fibrosis scores automatically, and make it harder for obvious warning signs to get missed. Emerging work on machine learning for advanced fibrosis screening in MASLD at the primary care level points in that direction. So does the broader case for AI-augmented stratification when current workflows depend too heavily on provider awareness and follow-through. If primary care is too overloaded to catch every case manually, then part of the answer may be building better systems that do more of that first-pass triage automatically.

That would not solve everything. But it would be better than pretending that an overloaded system will somehow start identifying patients earlier on its own.

I wrote years ago about the challenge of diagnosing NASH because it was obvious even then that delayed recognition was costing people precious time. What is striking now is how much the challenge has changed. We are no longer waiting for diagnostic science to begin. We are at a stage where many of the right pieces already exist, but they are still not being used consistently enough to protect patients.

That is the real test now. Not whether we can keep talking about MASLD and MASH, but whether the healthcare system will actually build screening and follow-up into routine care before it is too late.

AHRQ chart showing NAFLD-related inpatient stays rising from 370,900 in 2016 to 702,500 in 2022

Federal eyes are finally on NAFLD. It’s about time.

Federal eyes are finally on NAFLD. It’s about time.

In May 2024, I traveled to Washington, D.C. to meet with AHRQ Director Robert Valdez and talk about the need for the federal government to take NAFLD seriously. The American Liver Foundation and many patient advocates had been pushing for that kind of attention for years, because you cannot address a disease affecting nearly 100 million Americans if you are not even measuring it properly. That mission has been central to why I started writing here in the first place.

You cannot address a disease affecting nearly 100 million Americans if you are not even measuring it properly.

That is why AHRQ’s newly released report, Inpatient Stays Related to Nonalcoholic Fatty Liver Disease, 2016–2022, is such an important milestone. It is the first federal report of its kind focused specifically on NAFLD, and while it looks at only one part of the picture—hospitalizations—it still tells us something important. The government is finally beginning to quantify the burden of this disease.

The headline number is striking: NAFLD-related inpatient stays increased 88.1% from 2016 to 2022, rising from 370,900 to 702,500 stays. That kind of increase should be setting off alarm bells, especially for a disease that remains so poorly understood outside liver and metabolic health circles.

AHRQ chart showing NAFLD-related inpatient stays rising from 370,900 in 2016 to 702,500 in 2022
AHRQ data show NAFLD-related inpatient stays rising sharply from 2016 to 2022.

But the most revealing finding may be that NAFLD usually showed up as a secondary diagnosis, not the main reason a patient was admitted. In fact, hospital stays where NAFLD was the principal diagnosis stayed essentially flat, between 5,300 and 5,500 cases per year. The big increase came from patients being hospitalized for other serious conditions while NAFLD sat in the background as a coexisting disease.

That is exactly why this illness has remained so easy to miss. NAFLD often hides in plain sight. It is frequently not the headline diagnosis, but part of the larger metabolic dysfunction that contributes to a patient’s declining health over time.

AHRQ also found that 93.4% of NAFLD-related stays had at least one comorbidity, compared with 78.2% of stays without NAFLD. The most common were hypertension, obesity, and diabetes with chronic complications. Patients with secondary NAFLD were also far more likely to be hospitalized with conditions like hepatitis, hepatic failure, pancreatic disorders, obesity, and other liver disease.

NAFLD often hides in plain sight. It is frequently not the headline diagnosis, but part of the larger metabolic dysfunction that contributes to a patient’s declining health over time.

None of that is surprising to those of us who have been advocating in this space. NAFLD does not exist in isolation. It sits at the center of the broader metabolic health crisis, intersecting with obesity, diabetes, cardiovascular risk, and liver-related complications in ways the healthcare system still does a poor job of recognizing early. I have written before about the stigma surrounding liver disease and about how metabolic health conversations are often distorted by denial, confusion, and bad assumptions.

The report also found that patients with NAFLD-related stays were more likely to be between 45 and 64 years old than patients without NAFLD. That matters because it reinforces that this is not some niche condition affecting only the very old or very sick. It is hitting people in the middle of their lives, often while they are still working, raising families, and assuming that fatigue, weight gain, or abnormal labs are someone else’s problem.

For me, this report matters not just because of what it says, but because of what it represents. For years, fatty liver disease has existed in a strange policy blind spot. The prevalence is enormous, the complications are serious, and yet the public-health response has lagged badly behind. We have had growing awareness among specialists, more patient advocacy, and finally the beginning of treatment progress, but federal attention has not kept pace.

This report does not solve that problem by itself, but it does mark a turning point. Once the federal government starts measuring something, it becomes much harder to pretend it does not exist.

The American Liver Foundation recently applauded the report and said a more comprehensive AHRQ study is expected later this year. That is exactly what needs to happen next. Hospitalization data is only one slice of the story. We also need better federal data on prevalence, diagnosis, treatment, complications, and cost.

The most important takeaway here is not just that NAFLD-related hospital stays are rising sharply. It is that the federal government has finally begun to put its eyes on a disease that has remained everywhere and nowhere at the same time. That is overdue, but it is also real progress, and for patients and advocates who have been pushing for years, it is a meaningful step in the right direction.

Wegovy Receives Accelerated FDA Approval To Treat MASH

For many years doctors have told me that the best treatment for NAFLD/NASH (now referred to medically as MAFLD/MASH) was simply losing weight. That’s because we did not have any pharmaceutical treatments (until ezdiffra (resmetirom) from Madrigal in 2024), and until late stage fibrosis & cirrhosis develops, most liver disease is fully reversible.

On August 15, 2025, the FDA granted accelerated approval to Wegovy (semaglutide 2.4 mg) for treating adults with non-cirrhotic MASH and moderate to advanced liver fibrosis. This is an enormous milestone in the treatment of this disease. This makes Wegovy the first GLP‑1 receptor agonist to earn that distinction, and only the second overall drug to treat MASH.

GLP-1 drugs have obviously been all the rage for weight loss, and there has been some off-label use of them to treat liver disease like MASH, but in the Phase III ESSENCE trial, after 72 weeks, 63% of patients on Wegovy saw their steatohepatitis resolved without any worsening of fibrosis, compared to just 34% with placebo. And 37% saw an improvement in fibrosis with no worsening of inflammation, versus 22% in the placebo group. So it is not just helping patients lose weight but showing meaningful improvement for liver disease.

Dr. Martin Holst Lange, Novo Nordisk’s Chief Scientific Officer, put it bluntly: “Wegovy is now uniquely positioned as the first and only GLP‑1 treatment approved for MASH, complementing the already proven weight loss, cardiovascular benefits and extensive body of evidence linked to semaglutide”

Living with liver disease will still require lifestyle changes; these are foundational to the process. But now, there’s medicine that can resolve inflammation and heal fibrosis, beyond just nudging the scale downward. A tremendous step forward!

Our healthcare system is failing us

The energy in the room was electric. Packed to standing-room-only capacity, it held diverse representatives from nations as far afield as Qatar, Africa, and Brazil. These were not just academics or clinicians—they were heavy hitters in global health, some of whom had spent decades shaping the fight against diseases like HIV, malaria, and obesity. And yet, amidst this impressive gathering, a dark truth emerged: our healthcare system is failing millions of people with fatty liver diseases, including Non-Alcoholic Fatty Liver Disease (NAFLD) and its more severe form, Non-Alcoholic Steatohepatitis (NASH).

Dr. Christoph Benn, an influential early leader of the world-renowned Global Fund, did not mince words. During the discussion, he bluntly stated that until invited to this event, he’d never heard of NAFLD or NASH—not by these names, nor by their newer terminology, MASLD and MASH. His message was painfully clear: if a disease impacts an estimated 100 million Americans and remains largely invisible on the global stage, then the system designed to promote awareness and action has failed. What’s more, the 2024 Lancet publication on global health—an agenda-setting document for the next decade that for the first time is making a major shift from infectious diseases to non-communicable diseases (NCDs) —makes no mention of liver disease at all. Zero.

Let that sink in. Our healthcare policymakers are flying blind on an epidemic of massive proportions.

“100 million Americans are impacted by NAFLD, yet it remains invisible on the global stage.”

It was late September 2024, and for the first time in history there was a United Nations General Assembly (UNGA) sidelines event focused on liver disease, specifically MAFLD/MASH. UNGA Week is an important series of side events that include panel discussions, focus groups, and gatherings of global leaders and experts, often taking place in parallel to the formal UNGA sessions and are organized by UN member states, UN agencies, non-governmental organizations (NGOs), and private sector groups. These UNGA sidelines are key opportunities for advocacy, coalition-building, and policy discussions on pressing global issues like health, climate change, education, and sustainable development.

I have attended many NASH-related conferences and panel discussions in the years since I started NASHAWARE and began working with ALF, but they were also from a US-centric standpoint, and so the global viewpoints that were expressed during this amazing UNGA session hosted by The Economist Impact were refreshing and invigorating. The real eye-opener for me was how far we really have to go to make an impact in global health policy. You may have thought that with NASH drugs being a hot multi-billion dollar industry that there would be at least some action on the policy front, but other than ALF’s recent success in helping secure funding for the first US government-funded NAFLD study there really hasn’t been anything of note, and as the participants pointed out, plenty of missed opportunities.

The stakes have ever been higher or more clear, as illustrated by a sobering statistic from Dr. Arun Sanyal. “When a person shows up a emergency room for the first time with a complication of cirrhosis, two out of three individuals, it is the first day their liver disease has been diagnosed.” This is not just an oversight; it’s a systemic failure—a glaring indictment of our approach to prevention, early detection, and education. As Dr. Jeffrey Lazarus put it: “For everyone working in public health, global health, even health economics…it’s not that we’re not on their agenda. Some of them don’t even know this disease exists.”

For 20 or more years, the entire healthcare system has failed that patient.” – Dr. Arun Sanyal

Globally, countries like Qatar offer a blueprint for action. Their Minister of Health, Her Excellency Al Kuwari, spoke about how liver testing has been integrated into national health screenings. By embedding obesity and diabetes monitoring into the fight against liver disease, Qatar has not only halted the growth of obesity but also set a bold target to reduce it by 8% by 2030. “Yes we need to continue to study this, but we have enough data to take action” she declared. While they have the benefit of a small and affluent population, they can still inspire other nations through action.

Johanna Ralston, CEO of the World Obesity Foundation, made the observation that NAFLD is both “everywhere and nowhere.” Her point was clear: the disease is ubiquitous, affecting millions, yet remains absent from critical discussions on high-priority non-communicable diseases by organizations like the WHO. “It’s an exciting time for all of us working in this metabolic health space,” she mentioned, highlighting the ways that all of the various disease communities are coming together. “The timing is now,” Dr Sanyal added, echoing the call for action and collaboration to combat this invisible epidemic.

Contrast this with the fragmented and often lethargic approach in the U.S., where red tape, special interests, and stigma hinder progress. For instance, stigma around liver diseases being linked to alcohol persists, leading to misconceptions even within families. This stigma discourages both patients and policymakers from engaging in meaningful discussions, let alone action. We are also facing an uphill battle on messaging, which is hindered by a lack of clear and concise messages, even around the basic facts like what to call it (several panelists misstated the new terminology). Advocacy groups like the American Liver Foundation are pushing against this tide but are hindered by limited budgets and an uphill battle for donor dollars.

So, what’s the solution? The answer lies in disruptive advocacy—moving beyond just raising awareness to shaking the very foundations of our healthcare and political systems. As a former UK NHS legal counsel argued at the event, awareness campaigns often fall victim to shifting political winds. Instead, we must demand accountability by presenting stark, undeniable truths: “The healthcare system is failing millions of Americans. Here are the X lives lost and Y economic costs of inaction. Here’s what we need to fix it, and here’s how politicians can be remembered for saving lives, not abandoning them.”

It’s also about partnership and focus. We need to stop seeing liver disease in isolation and address the elephant in the room: metabolic dysfunction. NAFLD and NASH are intrinsically tied to obesity, diabetes, and poor nutrition. Advocacy must break through silos and unite stakeholders across fields—from obesity-focused NGOs to diabetes organizations—to tackle the root causes. As one speaker put it, we need to see “the elephant in the room, not the individual trunk or legs.”

The medical community must also adapt its approach to address the growing burden of NAFLD and NASH. Overspecialization within healthcare often creates silos that hinder a comprehensive approach to these diseases. Specialists in hepatology, gastroenterology, endocrinology, and cardiology need to collaborate more effectively, sharing knowledge and resources to tackle the interconnected nature of metabolic dysfunction. Medical training and research funding must emphasize cross-disciplinary education and solutions, ensuring that future healthcare providers are equipped to address these complex, multifaceted conditions.

Yet even the most compelling arguments won’t resonate without clarity of messaging. Attendees mentioned using visuals that elicit emotional responses; imagine a basketball court: ten kids playing a game. Now imagine telling those watching that one of these kids will develop MASLD or MASH before adulthood. One in ten. That’s the kind of visceral imagery we need to cut through the noise and make statistics real.

And then there’s the power of technology. A young doctor from Africa highlighted how AI tools could amplify these efforts, from translating advocacy materials into multiple languages to identifying high-risk individuals. These tools are there; we just need the vision and will to use them.

The harsh reality is that the healthcare system—both in the U.S. and globally—has left millions to fall through the cracks. But we can change this narrative. By simplifying our message, demanding specific actions, and rallying patients, advocates, and healthcare professionals to disrupt the status quo, we can force the system to do better.

Because the stakes are too high, and the cost of inaction is measured in lives lost—a price we cannot afford to keep paying.

Liverfast offers a quick and non-invasive blood test to identify nafld/nash

One of the biggest challenges in tackling the NAFLD/NASH epidemic is that there has traditionally been no easy non-invasive way to detect it in patients. This is a large reason why there are tens of millions of people in the United States alone that are impacted but do not even know it.

That has changed significantly in the last year as a company called Fibronastics has released widely a simple blood screening test that can be used to detect levels of steatosis, inflammation activity, and fibrosis. The LIVERFASt test uses a machine learning algorithm to examine 10 separate biomarkers from the blood draw and uses a scoring system to provide results which normally cannot be identified without a biopsy.

This means that physicians now have a powerful non-invasive tool to help screen for liver illnesses or gauge the severity of diagnosed liver conditions without biopsy (huge!). Fibronastics has recently announced a partnership with The American Liver Foundation to provide free LIVERFASt tests for individuals who qualify, and most insurance companies as well as Medicare will now cover the tests as well.

The accuracy of the test has been well established with medical studies going back to 2019 concluding that it is both “reliable and reproducible”. The scoring system is easy-to-understand and arms patients with clear & concise information to utilize over the course of their journey with liver disease.

“It is a reliable, and reproducible tool which provides grading or staging of the three elementary features of NASH: steatosis, inflammatory activity and fibrosis”

As biopharma continues to search for effective medical treatments, LIVERFASt will become a critical tool in the early detection of NAFLD & NASH.

The Covid-19 Vaccine & Liver Disease

Covid-19 Vaccine

Many people living with Liver Disease have questions about the Covid-19 vaccine, including how effective it is and if there are any risks associated with it specifically related to Liver Disease. This article will attempt to summarize some of the publicly available information on vaccine efficacy and safety for those with Liver Disease. As always, you should consult with your doctor if you have specific questions or concerns.

Obesity is a Major Risk Factor in Covid-19 Cases – Perhaps the Largest

Obesity linked to increased severity in Covid-19

Strong evidence that obesity is a major risk factor in Covid-19 severity and poses an increased risk of death has now been demonstrated across multiple studies around the world. The evidence all points to obesity as the preexisting condition with the largest impact on unfavorable outcomes, across all age groups.

The data is especially striking for younger adults, long thought to be at a much lower risk for serious illness from Covid-19. One NYU Langone study of 3,615 Covid patients under 60 years of age showed that “Patients with a BMI of 30-34 were twice as likely to get admitted to the hospital or to be admitted to acute care. Patients with a BMI of 35 or higher were twice as likely to be admitted to the hospital, and three times as likely to end up in the intensive care unit.”

A CDC study found that of its patients, “89% had at least one underlying condition, with obesity being the most common for those between 18 and 64.” A Chinese study showed that obesity tripled the risk of a severe case versus those of normal weights.

Data from UK hospitalizations is even more stark, showing that obesity and metabolic syndrome are associated with a 10 times increase in death. In an article entitled “Covid 19 and the elephant in the room”, Dr. Aseem Malhotra states it bluntly; “OBESITY, THE REAL KILLER BEHIND COVID”

72.7% of patients admitted to ICU are overweight or obese and that those with the related metabolic syndrome have a tenfold increase in mortality from the virus.

Dr. Asseem Malhotra, NHS

Data from a set of studies in France recently published in The Lancet looked at the percentage of ICU patients with Covid that were obese versus the percentage of non-Covid ICU patients. It found a clearly higher rate of ICU admissions among obese patients for Covid vs other causes. This research is also anecdotally supported out of the NYC hospital data.

This blog has discussed the Obesity Epidemic many times before, and I’ve started examining some of the causes of it that are easier to control for. It was always clear that obesity & metabolic syndrome are important for far more than NASH, but this pandemic should serve as a clear wake-up call for the tens of millions of obese individuals around the world. We cannot hide from our health behind the well-intentioned shield of the Body Positivity movement. The warnings are now being shouted loud and clear:

“[P]eople with a body mass index of 30 or more should be taking the same precautions as someone over 65, regardless of their age.”

Dr. Carlos Galvani, Tulane Bariatric Center

NASH: 2020 Outlook

Around this time last year there were a number of news articles declaring 2019 “The Year of NASH” . Four companies were due to release Phase 3 trial results. Optimism was surging and awareness was beginning to catch on. So how did 2019 turn out, and what does the outlook for NASH in 2020 look like?

A year later:

  • Gilead had several Phase 3 studies end that failed to live up to expectations, eliminating Selonsertib as a serious treatment option
  • Intercept released mixed results for Ocaliva, but is pushing ahead for FDA Approval. If granted, it would be the first approved NASH treatement. Decision on approval should come after April 2020.
  • Abbvie (acquired Allergan) pushed their Phase 3 results for cenicriviroc from 2019 to late 2020.
  • Genfit delayed Phase 3 elafibranor results to Q1 2020. It remains a promising undercard.

So while we didn’t get any truly amazing results for treatment in 2019, we did make progress. The 2nd International NASH Day helped reach people across the globe. Awareness has been steadily growing.

And while we have yet to hear from Genfit on their treatment data, they did recently announce tremendeous progress in their quest for a non-invasive diagnostic test. Using a unique 4-biomarker algorithm they have been able to accurately identify NASH and significant fibrosis. Genfit plans to file for FDA approval of the test in 2020.

A reliable non-invasive test for NASH is in some ways even more important than a medical treatment. The danger from NASH comes from years of undiagnosed progression, and we already know that the liver damage NASH can cause is reversible in earlier stages of the disease.

The Stigma of Liver Disease

I do a lot of volunteer work with the American Liver Foundation. This frequently puts me in social settings at food & drink events where, upon hearing the name of the organization, I’m immediately confronted with the biggest stigma of Liver Disease. “Isn’t it a little odd to be talking about liver disease while holding a beer?”

I love these conversations, because the juxtaposition creates a teachable moment that is more likely than not to be remembered.

My response blows up their preconceptions. “Actually, there are over one-hundred types of liver disease that have nothing to do with alcohol. NASH is a serious progressive liver disease affecting over twenty million American’s alone”.
