The optimal follow-up for patients with metabolic dysfunction-associated steatotic liver disease (MASLD) has not yet been determined. Monitoring should include routine biochemistry, assessment of comorbidities, and noninvasive monitoring of fibrosis. European guidelines advise that patients with metabolic dysfunction-associated steatohepatitis (MASH), without worsening of metabolic risk factors, should be monitored at 2- to 3-year intervals. Patients with MASH and/or fibrosis should be monitored annually, and those with MASH cirrhosis at 6-month intervals.[40]European Association for the Study of the Liver; European Association for the Study of Diabetes; European Association for the Study of Obesity. EASL-EASD-EASO clinical practice guidelines for the management of non-alcoholic fatty liver disease. J Hepatol. 2016 Jun;64(6):1388-402.

Liver biopsy should not be repeated routinely, but may be considered on a case-by-case basis.[3]Rinella ME, Neuschwander-Tetri BA, Siddiqui MS, et al. AASLD practice guidance on the clinical assessment and management of nonalcoholic fatty liver disease. Hepatology. 2023 May 1;77(5):1797-835.

Given its association with the development of SLD and fibrosis, there are various recommendations for monitoring when long-term methotrexate treatment is required. The American College of Rheumatology recommends laboratory monitoring at baseline and then at regular intervals during treatment (every 2-4 weeks for the first 3 months, every 8-12 weeks for 3-6 months, every 12 weeks after 6 months).[173]Saag KG, Teng GG, Patkar NM, et al. American College of Rheumatology 2008 recommendations for the use of nonbiologic and biologic disease-modifying antirheumatic drugs in rheumatoid arthritis. Arthritis Rheum. 2008 Jun 15;59(6):762-84.

They also recommend restricting the use of methotrexate in patients with suspected MASLD to those who have normal liver biochemistry and do not have advanced fibrosis, as detected by noninvasive testing. The American College of Dermatology recommends patients with psoriasis undergo fibrosis-4 serologic testing and transient elastography at baseline and yearly during treatment if they are at risk for hepatotoxicity.[174]Menter A, Gelfand JM, Connor C, et al. Joint American Academy of Dermatology-National Psoriasis Foundation guidelines of care for the management of psoriasis with systemic nonbiologic therapies. J Am Acad Dermatol. 2020 Jun;82(6):1445-86.

Laboratory monitoring at baseline and every 3-6 months is recommended, with liver biopsy used in case of abnormal transient elastography results or persistently abnormal liver biochemistry findings.[30]Fontana RJ, Liou I, Reuben A, et al. AASLD practice guidance on drug, herbal, and dietary supplement-induced liver injury. Hepatology. 2022 Jul 27 [Epub ahead of print].

Transient elastography and/or liver biopsy are also recommended once 3.5 to 4.0 g of cumulative methotrexate exposure has been reached.
Patients with cirrhosis, and patients who have evidence of advanced fibrosis or cirrhosis on noninvasive testing, should be offered screening for hepatocellular carcinoma.[32]Wattacheril JJ, Abdelmalek MF, Lim JK, et al.

Screening is initially performed with ultrasound, with or without serum alpha-fetoprotein.[175]Heimbach J, Kulik LM, Finn R, et al. AASLD guidelines for the treatment of hepatocellular carcinoma. Hepatology. 2018 Jan;67(1):358-80.

All patients with cirrhosis should also undergo surveillance for portal hypertension with esophagogastroduodenoscopy when cirrhosis is first diagnosed.[176]Garcia-Tsao G, Sanyal AJ, Grace ND, et al. Prevention and management of gastroesophageal varices and variceal hemorrhage in cirrhosis. Hepatology. 2007 Sep;46(3):922-38.

http://www.ncbi.nlm.nih.gov/pubmed/17879356?tool=bestpractice.com
Patients with varices should be treated with prophylactic measures.
All patients with MASH cirrhosis should be referred to a transplant center after the development of the first complication of liver disease (ascites, encephalopathy, variceal bleeding, and primary liver cancer).
