These findings suggest that health care systems should prepare for “large increases” in cases of hepatocellular carcinoma (HCC) and need for liver transplants, reported lead author Phuc Le, PhD, MPH, of the Cleveland Clinic, and colleagues.
“Following the alarming rise in prevalence of obesity and diabetes, NAFLD is projected to become the leading indication for liver transplant in the United States in the next decade,” Dr. Le and colleagues wrote in their abstract for the annual meeting of the American Association for the Study of Liver Diseases. “A better understanding of the clinical burden associated with NAFLD will enable health systems to prepare to meet this imminent demand from patients.”
To this end, Dr. Le and colleagues developed an agent-based state transition model to predict future prevalence of NAFLD and associated outcomes.
In the first part of the model, the investigators simulated population growth in the United States using Census Bureau data, including new births and immigration, from the year 2000 onward. The second part of the model simulated natural progression of NAFLD in adults via 14 associated conditions and events, including steatosis, nonalcoholic steatohepatitis (NASH), HCC, liver transplants, liver-related mortality, and others.
By first comparing simulated findings with actual findings between 2000 and 2018, the investigators confirmed that their model could reliably predict the intended epidemiological parameters.
Next, they turned their model toward the future.
It predicted that the prevalence of NAFLD among US adults will rise from 27.8% in 2020 to 34.3% in 2050. Over the same timeframe, prevalence of NASH is predicted to increase from 20.0% to 21.8%, proportion of NAFLD cases developing cirrhosis is expected to increase from 1.9% to 3.1%, and liver-related mortality is estimated to rise from 0.4% to 1% of all deaths.
The model also predicted that the burden of HCC will increase from 10,400 to 19,300 new cases per year, while liver transplant burden will more than double, from 1,700 to 4,200 transplants per year.
“Our model forecasts substantial clinical burden of NAFLD over the next three decades,” Dr. Le said in a virtual press conference. “And in the absence of effective treatments, health systems should plan for large increases in the number of liver cancer cases and the need for liver transplant.”
During the press conference, Norah Terrault, MD, president of the AASLD from the University of Southern California, Los Angeles, noted that all of the reported outcomes, including increasing rates of liver cancer, cirrhosis, and transplants are “potentially preventable.”
Dr. Terrault went on to suggest ways of combating this increasing burden of NAFLD, which she referred to as metabolic dysfunction–associated steatotic liver disease (MASLD), the name now recommended by the AASLD.
“There’s no way we’re going to be able to transplant our way out of this,” Dr. Terrault said. “We need to be bringing greater awareness both to patients, as well as to providers about how we seek out the diagnosis. And we need to bring greater awareness to the population around the things that contribute to MASLD.”
Rates of obesity and diabetes continue to rise, Dr. Terrault said, explaining why MASLD is more common than ever. To counteract these trends, she called for greater awareness of driving factors, such as dietary choices and sedentary lifestyle.
“These are all really important messages that we want to get out to the population, and are really the cornerstones for how we approach the management of patients who have MASLD,” Dr. Terrault said.
In discussion with Dr. Terrault, Dr. Le agreed that increased education may help stem the rising tide of disease, while treatment advances could also increase the odds of a brighter future.
“If we improve our management of NAFLD, or NAFLD-related comorbidities, and if we can develop an effective treatment for NAFLD, then obviously the future would not be so dark,” Dr. Le said, noting promising phase 3 data that would be presented at the meeting. “We are hopeful that the future of disease burden will not be as bad as our model predicts.”
The study was funded by the Agency for Healthcare Research and Quality. The investigators disclosed no conflicts of interest.
