, based on a large-scale meta-analysis of longitudinal data.
These findings emphasize the multisystemic nature of MASLD, suggesting that broader treatment targets are needed to reduce systemic events and end organ complications, reported lead author Kai En Chan, MBBS, of the National University of Singapore, and colleagues.
“[D]espite the substantial impact of MASLD, with direct medical costs estimated to reach $103 billion in the United States alone, a comprehensive umbrella meta-analysis of the longitudinal complications associated with MASLD has yet to be conducted,” the investigators wrote in Clinical Gastroenterology and Hepatology, noting that key outcomes associated with sex and disease severity have yet to be elucidated. “A comprehensive understanding of the spectrum of clinical complications associated with MASLD is thus crucial in developing effective disease management strategies and optimizing the allocation of limited healthcare resources.”
To this end, the investigators analyzed data from 129 studies reporting longitudinal risks of clinical outcomes among adults with MASLD. Assessed complications spanned a broad array of organ systems and pathologies. Cardiovascular and oncologic conditions predominated, while chronic kidney disease, liver-related outcomes, gallstone formation, dementia, and reflux esophagitis were also considered.
The analysis revealed significant associations between MASLD and — in ascending level of risk — chronic kidney disease (hazard ratio [HR], 1.38), cardiovascular diseases (HR, 1.43), cancer (HR, 1.54), prediabetes (HR, 1.69), hypertension (HR, 1.75), diabetes (HR, 2.56), and metabolic syndrome (HR, 2.57).
Across cardiovascular diseases, MASLD raised risk of hypertension the most, by 75%. Among cancer types, MASLD increased risk of hepatocellular carcinoma to the greatest degree, by more than fourfold.
No significant sex-specific differences in MASLD-associated risk were detected for cancer, chronic kidney disease, diabetes, or cardiovascular disease, although the investigators urged a cautious interpretation of these findings, since relevant data were scarce.
“It is imperative to understand that MASLD is a complex and multifaceted condition that requires a comprehensive approach to recognition and treatment beyond that of the hepatologist alone,” the investigators wrote.
They also suggested that the link between MASLD and cancer deserves particular attention.
“Although the mechanism by which MASLD gives rise to cardiovascular disease and diabetes has been thoroughly researched, the pathophysiology of MASLD leading to extrahepatic carcinogenesis is less well understood and has been postulated to be linked to chronic inflammation and dysregulation of the gut microbiome in MASLD,” they wrote.
Lastly, considering the multiprong association between MASLD and so many complications, the investigators recommended broader clinical metrics for measuring outcomes in patients with MASLD.
“With the synergistic increases of metabolic diseases globally, treatment targets should in turn act beyond the resolution of fibrosis but also to reduce systemic end organ complications,” they concluded.The investigators disclosed relationships with AbbVie, Echosens, Gilead Sciences, and others.
In a massive meta-analysis of 129 studies that included over 6 million participants, Chan and colleagues evaluated the associations of MASLD with incident hepatic and extrahepatic outcomes. They report numerous associations for MASLD with metabolic, cardiovascular, and renal events as well as with gastrointestinal, hepatobiliary, and other types of cancers.
The unimpeded pace of the obesity pandemic remains a steady driver of the rise in the burden of metabolic syndrome and its components, including MASLD. Thus, approaches to tackle the rising burden of metabolic diseases including MASLD should start with the root driver, obesity. It is also imperative to consider addressing the cardiometabolic milieu in any approach designed to specifically target MASLD/MASH. Lifestyle modifications that include weight loss, smoking cessation, and avoidance of alcohol use may help reduce risks of cardiovascular disease and cancer, the leading causes of death in patients with MASLD. Anticipated pharmacologic therapies for MASH should not only improve liver endpoints but also have a beneficial or, at minimum, neutral extrahepatic effects on coexisting cardiometabolic conditions.
