Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease worldwide and can progress to serious complications, including metabolic dysfunction-associated steatohepatitis (MASH), cirrhosis, end-stage liver disease, and hepatocellular carcinoma. Predisposing risk factors for MASH include obesity, type 2 diabetes, dyslipidemia, and metabolic syndrome. Patients with MASH often experience significant impairments in their health-related quality of life and other patient-reported outcomes (PROs), particularly in physical functioning domains, fatigue, and vitality.

Article Synopsis
  • Several scientific associations suggest using a combination of non-invasive tests to identify high-risk patients for metabolic dysfunction-associated steatohepatitis (MASLD), but the cost-effectiveness of these methods is not yet known.
  • A cost-utility model was created to evaluate the cost-effectiveness of various screening strategies for high-risk MASLD patients, particularly those with type 2 diabetes or obesity, comparing the use of initial and secondary testing methods.
  • The study found that while all screening strategies involve additional costs, they lead to significant long-term savings and are deemed cost-effective, reinforcing the recommendation to implement these screening methods in primary care settings.

Alcohol-related liver disease and metabolic-dysfunction-associated steatotic liver disease are the most common causes of chronic liver disease. Globally, alcohol intake, and metabolic syndrome driven by excessive caloric intake and sedentary lifestyle have steadily increased over the past decades. Given the high prevalence rates of both excessive alcohol consumption and components of metabolic syndrome, both can frequently coexist in the same individuals and impact their lives.

Integrating biomarkers into a comprehensive strategy is crucial for precise patient management, especially considering the significant healthcare costs associated with diseases. Current studies emphasize the urgent need for a paradigm shift in conceptualizing nonalcoholic fatty liver disease (NAFLD), now renamed metabolic dysfunction-associated steatotic liver disease (MASLD). Biomarkers are emerging as indispensable tools for accurate diagnosis, risk stratification, and monitoring disease progression.

Metabolic-dysfunction associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is a growing global health concern with significant implications for oncogenesis. This review synthesizes current evidence on the association between MASLD and cancer risk, highlighting its role as a risk factor for both intrahepatic and extrahepatic malignancies. MASLD is increasingly recognized as a major cause of hepatocellular carcinoma (HCC), with its incidence rising in parallel with the prevalence of metabolic dysfunction.

Background: A recent name change of nonalcoholic fatty liver disease (NAFLD) or metabolic dysfunction-associated fatty liver disease (MAFLD) to metabolic dysfunction-associated steatotic liver disease was primarily driven by potential stigma associated with the terminology. This stigma can be different between patients and healthcare providers and differ according to geographic regions of the world. Our aim was to better understand stigma and disease burden among patients with NAFLD enrolled in the global survey from Saudi Arabia (SA).

Liver disease prevalence, severity, outcomes and hepatic risk factors (for example, unhealthy diet) are heavily affected by socioeconomic status and food insecurity. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disease globally and is likely to co-occur with other liver diseases associated with food insecurity. Though weight reduction and adopting a healthy diet can reverse the course of MASLD, gaps between recommendations and practice transcend individual responsibility and preference.
