A caller model for diagnosis
The 2024 European objective believe guidelines present a pivotal terminology shift, replacing NAFLD (non-alcoholic fatty liver disease) pinch MASLD (metabolic dysfunction-associated steatotic liver disease) and NASH pinch MASH (metabolic dysfunction-associated steatohepatitis). This renaming is not conscionable semantic-it provides a pathophysiologically grounded, inclusive classification strategy based connected nan beingness of hepatic steatosis and astatine slightest 1 cardiometabolic consequence factor.
Importantly, MASLD is now grouped nether nan umbrella of "steatotic liver disease" (SLD), on pinch alcohol-associated liver illness (ALD), cryptogenic steatosis, and different causes. A caller subcategory-MetALD (MASLD pinch mean intoxicant use)-acknowledges mixed etiologies seen successful objective practice. Individuals pinch MetALD person chopped objective profiles and are astatine heightened consequence for cardiovascular and liver-related complications.
Risk factors and pathogenesis
The guidelines accent nan tight nexus betwixt MASLD and metabolic disorders specified arsenic obesity, type 2 glucosuria (T2D), dyslipidaemia, and hypertension. Genetic predispositions (e.g., PNPLA3, TM6SF2), age, antheral sex, postmenopausal status, polycystic ovary syndrome, and obstructive slumber apnoea besides elevate consequence for illness progression to MASH and fibrosis.
MetALD is highlighted arsenic an particularly high-risk subgroup. Even mean intoxicant depletion synergistically worsens hepatic wounded successful nan discourse of metabolic dysfunction. Guidelines now discourage immoderate intoxicant intake successful patients pinch MASLD and urge validated devices aliases biomarkers for much meticulous intoxicant usage assessment.
Screening and monitoring: a targeted, non-invasive approach
Routine screening for MASLD successful nan wide organization is not recommended owed to costs and debased yield. Instead, nan attraction is connected high-risk groups: individuals pinch T2D, cardinal obesity pinch different cardiometabolic consequence factor, aliases persistently elevated liver enzymes. A stepwise algorithm utilizing nan fibrosis-4 (FIB-4) scale is advocated. For intermediate-risk individuals, 2 strategies are offered: (A) second-line imaging specified arsenic transient elastography, aliases (B) intensified cardiometabolic guidance pinch repetition testing successful 12 months. This elastic model considers assets readiness and objective urgency. Non-invasive tests (NITs)-both serum biomarkers and imaging-based tools-are preferred for fibrosis staging, monitoring curen response, and prognostication. Liver biopsy is now reserved for prime cases pinch diagnostic uncertainty.
Lifestyle interventions: still nan cornerstone
Despite pharmacological advances, manner modification remains nan backbone of MASLD management. The guidelines urge a weight nonaccomplishment of ≥5% for reducing steatosis, 5–10% to trim inflammation, and ≥10% to reverse fibrosis. Normal-weight individuals tin besides use from humble (3–5%) weight nonaccomplishment owed to underlying metabolic derangements.
The Mediterranean diet-rich successful vegetables, legumes, fish, nuts, and olive oil-is nan dietary exemplary of choice. Ultra-processed foods, sugar-sweetened beverages, and intoxicant should beryllium minimized. At slightest 150 minutes of mean aliases 75 minutes of vigorous beingness activity per week is advised, pinch a attraction connected sustainability and entree to multidisciplinary support.
Pharmacological options: emerging but promising
Several pharmacologic agents-initially developed for glucosuria and obesity-have shown committedness successful MASLD: (i) Incretin mimetics specified arsenic semaglutide and tirzepatide are nan astir validated. (ii) SGLT2 inhibitors, metformin, and statins, while lacking histologic proceedings endpoints, amended liver enzymes, trim hepatic fat, and little cardiovascular risk. (iii) Resmetirom, a thyroid hormone receptor β-agonist, received accelerated FDA support for non-cirrhotic MASH pinch shape F2 fibrosis aliases greater, based connected nan MAESTRO-NASH trial. These developments propose a move therapeutic scenery is emerging, moving MASLD guidance person to targeted, individualized therapy.
Bariatric room and end-stage disease
Bariatric/metabolic room remains nan astir effective semipermanent involution for patients pinch terrible obesity and MASLD. Trials show that procedures for illustration gastric sleeve aliases Roux-en-Y bypass resoluteness MASH and amended fibrosis successful galore cases. Surgery besides reduces awesome cardiovascular and hepatic outcomes. For patients pinch compensated cirrhosis, room should only beryllium considered astatine knowledgeable centres pursuing broad consequence assessment. Endoscopic weight-loss procedures are still investigational successful this context. At nan end-stage spectrum, liver transplantation remains nan definitive therapy for patients pinch decompensated cirrhosis aliases hepatocellular carcinoma (HCC). Careful cardiometabolic appraisal is basal to optimize outcomes post-transplant. Nutritional guidance to forestall sarcopenia and hepatic decompensation is besides important successful patients undergoing mean weight loss.
Looking ahead: integration and prevention
The caller guidelines underscore nan request for integrated care. Effective MASLD guidance spans hepatology, endocrinology, nutrition, superior care, and nationalist health. Prevention strategies-targeting obesity, nutrient policy, and wellness literacy-remain captious astatine nan organization level. The authors telephone for broader implementation of multidisciplinary programs and continued investigation into caller diagnostics, therapeutics, and attraction transportation models.
