They can provide new insights into complex physiological mechanisms and potential therapeutic targets, increasing our knowledge of NAFLD. Furthermore, they represent a suitable alternative to in vivo models at early stages of drug development (Romualdo et al., 2021; Beisner et al., 2021; Eilenberger et al., 2020). The main 3D in vitro models used for NAFLD –spheroids, organoids, and microfluidic devices– are detailed in the following section. Primary human hepatocytes (PHH), primary non-parenchymal cells (PNPC), stem cells and tumor-derived cell lines (cyan panel) can all be used to create two-dimensional (2D) and three-dimensional (3D) models for NAFLD (pink panel). 2D cultures (e.g., monocultures and co-culture) are denoted by a single or several cell types growing in a monolayer.
I Have Liver Cancer, But You Don’t Have To
Cirrhosis is severe and permanent scarring in your liver that prevents it from working properly. It’s estimated to occur in 0.15% to 0.27% of people in the United States. It’s often caused by viral infection or heavy alcohol consumption.
How should a patient be followed/monitored after diagnosis?
As the information that the biopsy delivers cannot entirely be replaced by accurate NITs, the efficacy of a drug will need to be proven by repeat liver biopsy. A study can rely on NITs like liver blood tests or liver stiffness or markers of fibrosis in the early phases of the investigation of a drug. These alcoholic liver disease early studies help to decide whether it is interesting to go on with that drug to the next phase. But in a later phase of development of a drug, before a drug can be approved by the authorities and be brought to the market, you need a phase III trial proving, on a liver biopsy, that the drug works.
Why is NAFLD/NASH important?
Because of these strands of fibrosis and zones of liver cell regeneration, the liver becomes very scarred and the surface becomes irregular and bumpy or “nodular” (See Section 1.b). This irregular and bumpy appearance of the liver is a hallmark of cirrhosis. In cirrhosis, the main functions of the liver can initially be preserved (compensated cirrhosis, Fig. 2). The liver will, however, struggle more and more to function properly as the disease progresses.
- This 3D model also captured antifibrotic effects following exposure to the compounds liraglutide and elafibranor.
- The diagnosis of NAFLD is usually based on the abnormal LFTs and scan being compatible with NAFLD, and ruling out other causes of liver problems.
- Fibrosis can lead to cirrhosis, which means that large strands of scar tissue alter the liver structure, with regenerating liver tissue in between.
- (A) The fat that is inside the abdominal cavity and in close contact with both the gut and the liver is called intra-abdominal or visceral fat.
- More recently, spheroids and organoids have become the 3D in vitro models of choice for studying NAFLD (Soret et al., 2021).

Because most people don’t have symptoms, these conditions aren’t easy to diagnose. Ultrasound examination using a Two-Dimensional Shear Wave Elastography and Attenuation Imaging has the potential to identify fibrosis stage. Coronary artery disease and malignancy followed by liver-related mortality are the most common causes of death in people with NASH. Patient advocacy groups and patient self-help groups are excellent contact points. All of them have very well-educated consultants and those groups are available in many European countries. Most groups have a helpline which you can use without the time limitations you normally have at your doctor’s appointment.
- In Figure 2B the distribution of the hallmarks of NAFLD/NASH across the studies is reported.
- This is called simple or isolated fatty liver, or non-alcoholic fatty liver (NAFL, without the “D” for disease).
- Although it’s very similar to alcohol-related liver disease (ARLD), NAFLD is not caused by drinking too much alcohol.
What Monitoring Is Recommended for NAFLD?
When you have NAFLD, the goal is to manage your symptoms, and to prevent your health from getting worse. Although NAFLD progresses very slowly, it is important to eat healthily and increase your physical activity/exercise levels (see Section 6). This will help to improve the health of your liver and lower your risk of worsening health. It is also important to consider adding a psychologist into the multidisciplinary team. Up to 20% of all patients with NASH have depression, which can be severe. This should not be managed in isolation but in line with the NASH treatment.
- People with cirrhosis are at risk of developing end stage liver failure or liver cancer.
- If they occur, they can include fatigue or discomfort in the upper right abdomen.
- To diagnose MASLD, your care team may use blood tests, imaging tests or a liver biopsy.
- We explored whether this shift in the field was promoted by a greater involvement of pharma, but did not observe any direct link, as most of the investigations remain hosted in academic settings.
Blood specimens, collected by the hospital nurse, were promptly sent to the medical laboratory center by the staff and processed within 2 h. Plasma glucose was determined using a blood glucose biochemical analyzer. Routine measurements of biochemical parameters, including serum lipids, liver enzymes, bilirubin, and renal function index, were conducted using enzymatic methods. Additionally, information regarding a patient’s history of hypertension, hypoglycemic agents, and lipid-lowering drugs was obtained by the attending physician upon admission.
Questions to Ask Your Doctor
Here, FFA induces hepatic IR, gluconeogenesis, very low-density lipoprotein (VLDL) release, as well as an increase of pro-inflammatory adipokines. Some sphingolipids, besides being correlated with IR, are also linked to hepatic oxidative stress and inflammation, suggesting their importance in NASH progression (Apostolopoulou et al., 2018). Many people with chronic liver disease live for years after receiving a diagnosis. Your degree of liver damage plays a large role in determining how likely it is to affect your life expectancy. Cirrhosis is the top risk factor for the development of the most common type of liver cancer called hepatocellular carcinoma. About 80% to 90% of people who develop hepatocellular carcinoma have cirrhosis.
