Dietary and pharmacological treatment in patients with metabolic-dysfunction associated steatotic liver disease

Protective effects of Ginkgo biloba supplementation on clinical outcomes in metabolic dysfunction-associated steatotic liver disease

BACKGROUND

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern linked to increased risks of cardiovascular disease, chronic kidney disease (CKD), and premature mortality. Ginkgo biloba has shown potential therapeutic benefits in conditions characterized by metabolic dysfunction. This study aimed to evaluate the potential protective effects of Ginkgo biloba supplementation on overall survival (OS) and the incidence of cardiovascular and renal outcomes specifically in MASLD patients.

METHODS

This cohort study included 402,476 participants from the UK Biobank, categorized into MASLD and No steatotic liver disease (SLD) cohorts. Ginkgo biloba users and non-users were compared using inverse probability of treatment weighting to balance baseline characteristics. Clinical outcomes were assessed using Cox proportional hazards models, with subgroup analyses.

RESULTS

Ginkgo biloba supplementation was associated with significantly improved OS [hazard ratio (HR) = 0.79, 95 % confidence interval (CI): 0.64-0.98, p = 0.034) and reduced risks of cardiovascular events (HR = 0.82, 95 % CI: 0.66-1.00, p = 0.012) and CKD (HR = 0.73, 95 % CI: 0.56-0.96, p = 0.012) in the MASLD cohort, while no significant benefits were observed in the No SLD cohort. Subgroup analyses indicated enhanced benefits in older adults, males, individuals with BMI ≥ 25 kg/m², and diabetic patients. The beneficial effects were pronounced in patients with advanced fibrosis.

CONCLUSION

Ginkgo biloba supplementation is associated with improved survival and reduced cardiovascular and renal risks in MASLD patients, particularly in high-risk subgroups. These findings highlight the potential of Ginkgo biloba as an adjunctive therapy in MASLD management. This is the first large-scale study to examine the potential impact of Ginkgo biloba supplementation on clinical outcomes in MASLD, with fibrosis-stratified analyses providing insights into its differential effects across disease severity.

Comparative efficacy and safety of pharmacologic therapies for metabolic dysfunction-associated steatotic liver disease over 24 weeks in reducing liver steatosis and fibrosis: A network meta-analysis

AIMS

Metabolic-associated steatotic liver disease (MASLD) is a prevalent chronic liver condition associated with significant morbidity and mortality. Effective pharmacological interventions targeting liver steatosis and fibrosis are essential to improving patient outcomes. This study aims to systematically compare the efficacy and safety of various pharmacologic therapies for MASLD over 24 weeks using a comprehensive network meta-analysis.

MATERIALS AND METHODS

A systematic review and network meta-analysis were conducted on randomized controlled trials (RCTs) evaluating pharmacologic treatments for MASLD. The primary outcomes were changes in liver steatosis (measured by magnetic resonance imaging proton density fat fraction) and fibrosis (measured by magnetic resonance elastography-derived liver stiffness measurement), with safety assessed through adverse events. A Bayesian framework was employed to integrate and compare data across treatments, generating rankings for efficacy and safety.

RESULTS

A systematic search was conducted across databases, identifying 23 RCTs from 10 144 initial records. For steatosis reduction, resmetirom showed the most significant improvement (mean difference: -3.86, 95% confidence interval [CI]: -7.33 to -0.39) compared with placebo. In terms of fibrosis improvement, pegozafermin demonstrated the greatest effect (-4.85, 95% CI: -5.50 to -4.19). Most treatments showed acceptable safety profiles, with efruxifermin showing slightly higher adverse events (0.32, 95% CI: 0.06-0.70) compared with placebo.

CONCLUSIONS

This comprehensive network meta-analysis demonstrates the varying efficacy of pharmacologic interventions for MASLD, with resmetirom and pegozafermin emerging as particularly promising treatments for steatosis and fibrosis, respectively. While most treatments exhibited favourable safety profiles, careful monitoring is warranted, particularly with efruxifermin due to its slightly elevated adverse event profile. These findings provide valuable evidence to guide clinical decision-making in MASLD management, though longer-term studies are needed to confirm the durability of these therapeutic effects and further establish safety profiles.

Expanding the Use of SGLT2 Inhibitors in T2D Patients Across Clinical Settings

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are currently recommended in patients with type 2 diabetes (T2D) to reduce serum glucose levels. Moreover, robust evidence has clearly demonstrated their beneficial cardiovascular and renal effects, making this class of drugs pivotal for the treatment of T2D, especially when complicated by diabetic kidney disease or heart failure. However, several other comorbidities are frequently encountered in T2D patients beyond these long-term diabetes complications, especially in the internal medicine setting. For some of these comorbidities, such as MAFLD and cognitive impairment, the association with diabetes is increasingly recognized, with the hypothesis of a common pathophysiologic background, whereas, for others, a coincident epidemiology linked to the ageing of populations, including that of T2D subjects, may be advocated. In the effort of personalizing T2D treatment, evidence on the potential effects of SGLT2i in these different clinical conditions is accumulating. The purpose of this narrative review is to update current literature on the effects of SGLT2i for the treatment of T2D in different clinical settings beyond glycaemic control, and to elucidate potential molecular mechanisms by which they exert these effects.

Advancing precision medicine in metabolic dysfunction-associated steatotic liver disease

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), has become a pressing global health concern. The complexity of MASLD and the lack of universally effective treatments expose the limitations of current interventions, which focus mainly on lifestyle modifications. Here, we explore the multilayered nature of MASLD, emphasizing its pathophysiology in shaping future medical and lifestyle interventions from a personalized medicine perspective, based on individual molecular profiles. Additionally, we address the limitations of current animal models in reflecting human metabolic syndrome and sex-specific differences. We argue that a holistic approach, integrating social determinants of health, patient preferences, and adherence patterns, is essential for advancing MASLD management effectively.

Cell Homeostasis or Cell Death-The Balancing Act Between Autophagy and Apoptosis Caused by Steatosis-Induced Endoplasmic Reticulum (ER) Stress

Metabolic-dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver condition with potential progression to cirrhosis and impaired regeneration post-resection. A key mechanism underlying lipotoxicity is endoplasmic reticulum (ER) stress, particularly the activation of the unfolded protein response (UPR). This study investigates the interplay between lipid accumulation, endoplasmic reticulum (ER) stress, and cellular outcomes, focusing on the balance between autophagy and apoptosis. We cultured primary human hepatocytes (PHH) in a free fatty acid (FFA)-enriched medium for 120 h, assessing lipid accumulation, metabolism, and the expression of selected UPR markers. Additionally, we investigated the effects of lipid load on cell activity and growth in proliferating HepG2 cells. We observed that FFA uptake consistently induced ER stress, shifting cellular responses toward apoptosis under high lipid loads. Donor-specific differences were evident, particularly in lipid storage, excretion, and sensitivity to lipotoxicity. Some donors exhibited limited triglyceride (TAG) storage and excretion, leading to an excess of FFA whose metabolic fate remains unclear. Proliferation was more sensitive to lipid accumulation than overall cell activity, with even low FFA concentrations impairing growth, highlighting the vulnerability of regenerative processes to steatosis. The study elucidates how ER stress pathways, such as PERK-CHOP and IRE1α-JNK, are differentially activated in response to lipid overload, tipping the balance toward apoptosis in severe cases. The limited activation of repair mechanisms, such as autophagy, further emphasizes the critical role of ER stress in determining hepatocyte fate. The donor-dependent variability highlights the need for personalized strategies to mitigate lipotoxic effects and enhance liver regeneration in steatosis-related conditions.

Nutritional Strategies for Battling Obesity-Linked Liver Disease: the Role of Medical Nutritional Therapy in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) Management

PURPOSE OF REVIEW

This narrative review explores the role of Medical Nutritional Therapy (MNT) in managing Metabolic-Associated Steatotic Liver Disease (MASLD), previously known as nonalcoholic fatty liver disease. It aims to examine the effectiveness of specific nutritional strategies in preventing and treating this obesity-linked liver disease.

RECENT FINDINGS

Emerging evidence underscores the benefits of the Mediterranean diet, low-carbohydrate diets, and intermittent fasting in reducing liver fat, improving insulin sensitivity, and mitigating inflammation. Supplementing with vitamin E, omega-3 fatty acids, and silymarin can potentially reduce liver fibrosis and promote liver health. MNT is a key intervention for MASLD management, emphasizing dietary patterns, caloric restriction, and nutraceutical supplementation. Integrating these strategies with lifestyle modifications, including regular physical activity, offers a comprehensive approach to improving metabolic and liver outcomes in patients with MASLD. Further research is needed to refine and personalize these therapeutic interventions.

An updated overview on hepatocellular carcinoma in patients with Metabolic dysfunction-Associated Steatotic Liver Disease: Trends, pathophysiology and risk-based surveillance

Hepatocellular carcinoma (HCC) is a relevant complication occurring in individuals with advanced Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD). Recent epidemiological data suggest an alarming increase in the HCC burden worldwide, with a relevant proportion attributable to MASLD (up to 38 %), either in cirrhotic or non-cirrhotic livers. In view of the changing landscape of metabolic syndrome as "silent pandemic", this narrative review aims to provide an updated picture of the burden of HCC in individuals with MASLD. In the complex pathophysiological pathways linking insulin resistance to MASLD and cardiometabolic syndrome, metabolic inflammation appears a relevant driver of systemic as well as organ-specific complications. Novel insights from the field of immunology, gut-derived liver damage, and association with extra-hepatic cancers will be discussed. Finally, strategies for risk-based HCC surveillance (circulating biomarkers, prognostic models and polygenic risk scores) will be provided and the potential impact of novel drug targeting fibrosing Metabolic dysfunction-Associated Steatohepatitis (MASH) on incident HCC will be discussed.

Valorizing Agro‐Food Waste for Nutraceutical Development: Sustainable Approaches for Managing Metabolic Dysfunction‐Associated Steatotic Liver Disease and Related Co‐Morbidities

This comprehensive investigation delves into the interconnectedness of different features of cardiometabolic syndrome, such as metabolic dysfunction‐associated steatotic liver disease (MASLD), atherosclerotic cardiovascular disease (ASCVD), and gut dysbiosis, highlighting the crucial role of nutraceuticals in their management and prevention. Given the significant overlap in the pathophysiology of these conditions, the treatment with nutraceuticals, especially those derived from agro‐food waste, offers a promising, sustainable, and innovative approach to healthcare. The 2030 Agenda for Sustainable Development and the One Health concept are key frameworks for selecting the most interesting supply chain for the production of nutraceuticals from agro‐food waste, ensuring environmental sustainability, and innovative agricultural practices. In this review, the therapeutic potential of kiwifruit and apples has been explored, detailing how their bioactive compounds, like polyphenols, fiber, pectin, kaempferol, phloretin, and phlorizin, may contribute to the management of MASLD, ASCVD, and gut dysbiosis. Various extraction methods for active ingredients, including chemical, water, and enzyme extractions, are analyzed for their respective benefits and drawbacks. By integrating scientific research, sustainable agricultural practices, and innovative extraction methods, we can develop effective strategies to combat these pervasive health issues. This holistic approach not only enhances individual health outcomes but also supports broader environmental and societal goals, promoting a healthier future for all.

Association Between Percent Body Fat Reduction and Changes of the Metabolic Score for Insulin Resistance in Overweight/Obese People with Metabolic Dysfunction-Associated Steatotic Liver Disease

Purpose

This study investigated the relationship between the difference in percent body fat (∆PBF) decrease and the change in the metabolic score for insulin resistance (METS-IR) in Chinese overweight/obese people with combined metabolic dysfunction-associated steatotic liver disease (MASLD) after weight loss.

Patients and Methods

A total of 357 overweight/obese MASLD patients were included using a retrospective study method. The subjects were divided into two groups (< 5% and ≥ 5%) based on the ∆PBF. The changes in METS-IR (∆METS-IR) and metabolic indices before and after fat loss were compared between the two groups. Spearman correlation analysis was employed to investigate the correlation between METS-IR changes and the decrease in PBF. A linear regression model was fitted using a restricted cubic spline (RCS) curve to investigate the dynamic relationship between ∆METS-IR and ∆PBF.

Results

Following the fat reduction, both groups' body measurements and liver fat content exhibited a notable reduction, accompanied by a decline in METS-IR. In particular, the decrease in METS-IR was more pronounced in the group with a ≥5% decrease in PBF. Significant correlations were observed between ∆PBF and various insulin resistance indices. The correlation between ΔPBF and ∆METS-IR was noteworthy (r = 0.438, p < 0.001). RCS analysis revealed that when ΔPBF exceeded 3.2%, ∆METS-IR exhibited an upward trend with further reduction in PBF.

Conclusion

The reduction of PBF was closely associated with changes in METS-IR, indicating that fat loss is an effective method for improving insulin resistance in overweight/obese MASLD patients.

Diagnosis and management of metabolic dysfunction- associated steatotic liver disease in South Asians- A clinical review

Background

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed as nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of obesity and metabolic syndrome. It is mainly caused by insulin resistance. With the increased risk of visceral obesity in South Asians, the prevalence of MASLD is on the rise. The morbidity associated with MASLD and its complications, including hepatocellular carcinoma is projected to increase in this South Asian population.

Methods

In this narrative review we explore the diagnosis and management of MASLD in the South Asian population. We summarize the findings from the recent literature on the diagnostic methods and management options for MASLD in this population.

Results

Through our search we found no specific guidelines for the diagnosis and management of MASLD in the South Asian population. The existing general guidelines may not be applied to South Asian populations due to the differences in phenotype, genotype, social and cultural aspects. South Asian countries also have limited resources with the non-availability of newer pharmacotherapeutic agents.

Conclusion

The goal of this review is to guide obesity physicians and primary care providers to have a stepwise approach to treat patients at risk for MASLD with a main focus on interdisciplinary management most applicable to South Asian patients. More research is needed to formulate guidelines and algorithm that are specific for the South Asian population.

Protective Effect of High Adherence to Mediterranean Diet on the Risk of Incident Type-2 Diabetes in Subjects with MAFLD: The Di@bet.es Study

Background/Objectives: Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) increases the risk of Type-2 Diabetes (T2DM). The Mediterranean diet (MD) has shown advantages in the management of MAFLD and preventing co-morbidities; however, its relationship with T2DM development in MAFLD has been less investigated. We aimed to evaluate the association of MD adherence with the risk of incident T2DM in the Spanish adult population with MAFLD and according to their weight gain at 7.5 years follow-up. Methods: A cohort of 714 participants (without weight increment: 377; with weight increment: 337) from the Di@bet.es cohort study with MAFLD and without T2DM at baseline were investigated. Anthropometric, sociodemographic, clinical data, and a survey on habits were recorded. OGTT and fasting blood biochemistry determinations were made. Baseline adherence to MD was estimated by the adapted 14-point MEDAS questionnaire and categorized as high and low adherence. Results: In total, 98 people developed T2DM at follow-up. The high adherence to MD was inversely associated with the development of T2DM in both the overall population (0.52 [0.31-0.87]) and subjects without weight gain at follow-up (0.35 [0.16-0.78]). Conclusions: Our results suggest the protective effect of high adherence to MD regarding the risk of T2DM in subjects with MAFLD, with this health benefit being more evident in men with the absence of weight gain. These results support the recommendations for MD use in these patients.

Prevention and control of risk factors in metabolic and alcohol-associated steatotic liver disease

Steatotic liver disease (SLD), including metabolic dysfunction-associated steatotic liver disease (MASLD) and alcohol-associated liver disease (ALD), is the primary cause of illness and mortality. In particular, MASLD affects more than 30% of the global population, while ALD accounts for 5.1% of all diseases and injuries worldwide. The SLD spectrum includes a variety of clinical conditions, from mild fatty liver and inflammation to different stages of liver fibrosis. Additionally, both conditions (MASLD and ALD) can be complicated by hepatocellular carcinoma (HCC), while around one-third of ALD patients can also develop at least one alcohol‐associated hepatitis (AH) episode. Both of these diseases are also associated with multiple extrahepatic complications, such as cardiovascular disease, chronic kidney disease, and malignancies. In MASLD, the rapid rise in global obesity and type 2 diabetes mellitus (T2DM) prevalence due to Westernized lifestyles has led to an increase in the prevalence of MASLD. Thus, the prevention and control of cardiometabolic risk factors (CMRFs) are the cornerstone of its treatment. Hypertension and atherogenic dyslipidemia are also important CMRFs associated with MASLD. Susceptible individuals with MASLD are adversely affected by even a small amount of alcohol consumption (though there is no agreed definition of a small amount), increasing the risk of severe outcomes and a faster progression of liver disease. This review explores factors that play a role in the development of SLD, especially focusing on the management of CMRFs and levels of alcohol use to prevent liver disease progression.

Exploring Varied Treatment Strategies for Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a liver disorder characterized by steatosis with underlying metabolic risk factors. The prevalence of MASLD continues to rise, leading to increased patient risk of various complications. Recent research has been focused on new therapeutic strategies to reduce the incidence of MASLD and provide effective treatment plans to prevent further irreversible liver damage. The treatment approach is multifactorial, with a primary focus on weight loss and management of underlying comorbidities through lifestyle modifications, pharmacotherapy, or surgical options. Ongoing research is exploring new pharmacological therapies that could enhance the treatment of MASLD.

Metabolic-Dysfunction-Associated Steatotic Liver Disease (MASLD) after Liver Transplantation: A Narrative Review of an Emerging Issue

The development of steatotic liver disease after liver transplant (LT) is widely described, and epidemiological data have revealed an increased incidence in recent times. Its evolution runs from simple steatosis to steatohepatitis and, in a small proportion of patients, to significant fibrosis and cirrhosis. Apparently, post-LT steatotic disease has no impact on the recipient's overall survival; however, a higher cardiovascular and malignancy burden has been reported. Many donors' and recipients' risk factors have been associated with this occurrence, although the recipient-related ones seem of greater impact. Particularly, pre- and post-LT metabolic alterations are strictly associated with steatotic graft disease, sharing common pathophysiologic mechanisms that converge on insulin resistance. Other relevant risk factors include genetic variants, sex, age, baseline liver diseases, and immunosuppressive drugs. Diagnostic evaluation relies on liver biopsy, although non-invasive methods are being increasingly used to detect and monitor both steatosis and fibrosis stages. Management requires a multifaceted approach focusing on lifestyle modifications, the optimization of immunosuppressive therapy, and the management of metabolic complications. This review aims to synthesize the current knowledge of post-LT steatotic liver disease, focusing on the recent definition of metabolic-dysfunction-associated steatotic liver disease (MASLD) and its metabolic and multisystemic concerns.

A prospective study on the prevalence of at-risk MASH in patients with type 2 diabetes mellitus in the United States

BACKGROUND

There are limited data on the prevalence and treatment of at-risk metabolic dysfunction-associated steatohepatitis (MASH) among patients with type 2 diabetes (T2DM) in the United States.

AIM

To estimate the prevalence of at-risk MASH in a prospectively recruited cohort of adults with T2DM using new nomenclature endorsed by multiple societies.

METHODS

This prospective study enrolled adults aged ≥50 with T2DM from primary care and endocrinology clinics in southern California from 2016 to 2023. Metabolic dysfunction-associated steatotic liver disease (MASLD) was defined by an magnetic resonance imaging proton density fat fraction ≥5% and at least one metabolic risk factor without any other chronic liver disease or secondary cause for hepatic steatosis.

RESULTS

We included 530 adult patients with T2DM. The mean (±SD) age and body mass index (BMI) were 64.4 (±8.1) years and 31.5 (±6.1) kg/m2, respectively. Among patients with T2DM, the prevalence of MASLD, at-risk MASH and cirrhosis was 69.6%, 13.6% and 6.8%, respectively. Among patients with co-existing T2DM and obesity, the prevalence of MASLD, at-risk MASH and cirrhosis was 77.8%, 15.9% and 9.0%, respectively, and was higher than in participants without obesity (p < 0.0001, 0.0543 and 0.0128, respectively).

CONCLUSION

Among adults aged ≥50 years with T2DM, the prevalence of MASLD, at-risk MASH and cirrhosis is high, posing a significant risk for liver-related morbidity and mortality. Approximately 14% of patients with T2DM may be candidates for pharmacologic therapies specific to MASH-related fibrosis.

Metformin and the Liver: Unlocking the Full Therapeutic Potential

Metformin is a highly effective medication for managing type 2 diabetes mellitus. Recent studies have shown that it has significant therapeutic benefits in various organ systems, particularly the liver. Although the effects of metformin on metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction-associated steatohepatitis are still being debated, it has positive effects on cirrhosis and anti-tumoral properties, which can help prevent the development of hepatocellular carcinoma. Furthermore, it has been proven to improve insulin resistance and dyslipidaemia, commonly associated with liver diseases. While more studies are needed to fully determine the safety and effectiveness of metformin use in liver diseases, the results are highly promising. Indeed, metformin has a terrific potential for extending its full therapeutic properties beyond its traditional use in managing diabetes.
