Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States and worldwide. Though nonalcoholic fatty liver per se may not be independently associated with an increased risk for all-cause mortality, it is associated with a number of harmful metabolic risk factors, such as type 2 diabetes mellitus, hyperlipidemia, obesity, a sedentary lifestyle, and an unhealthy diet. The fibrosis stage is a predictor of all-cause mortality in NAFLD. Mortality in individuals with NAFLD has been steadily increasing, and the most common cause-specific mortality for NAFLD is cardiovascular disease, followed by extra-hepatic cancer, liver-related mortality, and diabetes. High-risk profiles for mortality in NAFLD include PNPLA3 I148M polymorphism, low thyroid function and hypothyroidism, and sarcopenia. Achieving weight loss through adherence to a high-quality diet and sufficient physical activity is the most important predictor of improvement in NAFLD severity and the benefit of survival. Given the increasing health burden of NAFLD, future studies with more long-term mortality data may demonstrate an independent association between NAFLD and mortality.

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and encompasses a spectrum of pathology from simple steatosis to inflammation and significant fibrosis that leads to cirrhosis. NAFLD and its comorbid conditions extend well beyond the liver. It is a multisystemic clinical disease entity with extrahepatic manifestations such as cardiovascular disease, type 2 diabetes, chronic kidney disease, hypothyroidism, polycystic ovarian syndrome, and psoriasis. Indeed, the most common causes of mortality in subjects with NAFLD are cardiovascular disease, followed by malignancies and then liver-related complications as a distant third. This review focuses on several of the key extrahepatic manifestations of NAFLD and areas for future investigation. Clinicians should learn to screen and initiate treatment for these extrahepatic manifestations in a prompt and timely fashion before they progress to end-organ damage.

Nonalcoholic fatty liver disease (NAFLD) is a multisystemic disease and a rapidly growing cause of chronic liver disease in children and adults worldwide. Diagnosis and management of extrahepatic manifestations of NAFLD, including cardiovascular disease (CVD), type 2 diabetes mellitus, metabolic syndrome, chronic kidney disease, obstructive sleep apnea, polycystic ovarian syndrome, hypothyroidism, psoriasis, and extrahepatic malignancy are crucial for the treatment of patients with NAFLD. The leading cause of death in NAFLD is primarily from CVD, followed by liver-related mortality, extrahepatic cancer, liver cancer, and diabetes-related mortality. Therefore, clinicians need to identify high-risk patients earlier in the disease course and be aware of the extrahepatic manifestations of NAFLD to improve liver disease outcomes. In this review, we focus on the monitoring and management of the extrahepatic manifestations of NAFLD.

The ongoing obesity epidemic and the increasing recognition of metabolic syndrome have contributed to the growing prevalence of nonalcoholic fatty liver disease (NAFLD), the most common form of liver disease worldwide. It is imperative to understand the incidence and prevalence of NAFLD as it is associated with a profound economic burden of hospitalizations, including the shifting trends in liver transplantation. The long-term cumulative healthcare cost of NAFLD patients has been shown to be 80% higher than that of non-NAFLD patients. We explore diagnostic challenges in identifying those with NAFLD who have a higher predilection to progress to end-stage liver disease. We aim to assess all-cause and cause-specific mortality as it relates to NAFLD.

Background:
s/Aims: The trends in mortality of hepatocellular carcinoma (HCC) and biliary tract cancers stratified by sex and race/ethnicity in the US continue to evolve. We estimated the sex- and race/ethnicity-based trends in HCC and biliary tract cancers-related mortality in US adults with a focus on disease burden.
Methods:
We performed a population-based analysis using the US national mortality records from 2018 to 2023. We identified HCC and biliary tract cancer using appropriate ICD-10 codes. Temporal trends in mortality were calculated by joinpoint analysis with annual percentage change (APC).
Results:
Annual age-standardized mortality from HCC decreased steadily with an APC of –1.4% (95% confidence interval [CI]: –2.0% to –0.7%). While there was a linear increase in intrahepatic cholangiocarcinoma-related mortality (APC: 3.1%, 95% CI: 1.2–4.9%) and ampulla of Vater cancer-related mortality (APC: 4.1%, 95% CI: 0.5–7.9%), gallbladder cancer-related mortality decreased (APC: –1.9%, 95% CI: –3.8% to –0.0%). Decreasing trends in mortality from HCC were noted in males, not females. HCC-related mortality decreased more steeply in racial and ethnic minority individuals compared with non-Hispanic White individuals. Racial and ethnic differences in trends in mortality for biliary tract cancers depended on the malignancy’s anatomical site.
Conclusions
While the annual mortality for HCC and gallbladder cancer demonstrated declining trends, ICC- and AVC-related mortality continued to increase from 2018 to 2023. Although racial and ethnic minority individuals in the US experienced disproportionately higher HCC and biliary tract cancer, recent declines in HCC may be primarily due to declines among racial and ethnic minority individuals and males.
