Studies suggest 20%–70% of patients with sarcoidosis have abnormal liver chemistries or abdominal imaging. Hepatic sarcoidosis may be complicated by portal hypertension (portal HTN) with or without cirrhosis. Few studies have reviewed the liver histopathology of sarcoidosis.</div></div><div><h3>Methods</h3><div>Searching the pathology database using the terms “sarcoidosis” and “liver,” patients were identified and cross-referenced to patients in the Sarcoidosis Clinic. Patients met the diagnostic criteria for sarcoidosis. Those with isolated granulomatous hepatitis were excluded. Demographics, abdominal imaging, biochemistries, and detailed histological features were cataloged.</div></div><div><h3>Results</h3><div>Patients were separated into 2 groups: those with portal HTN with or without cirrhosis (pHTN+) and those without portal HTN (pHTN-). Fifty-three patients had biopsies available for review (pHTN+, n = 33; pHTN-, n = 20). The groups did not differ in the location, type, or number of granulomas. The pHTN + group had more bile duct damage (<em>P</em> = .025) and loss (<em>P</em> = .019). Patients in the pHTN + group also had biliary cirrhosis, nodular regenerative hyperplasia, or outflow obstruction.</div></div><div><h3>Conclusion</h3><div>There are several causes for portal HTN in sarcoidosis. Thus, liver biopsy is essential in its evaluation. Bile duct damage and loss are associated with the presence of portal HTN and cirrhosis. Biliary abnormalities may occur independently of granulomatous inflammation, and can thus identify a subset of patients at risk for progressive liver disease.</div></div>","PeriodicalId":73130,"journal":{"name":"Gastro hep advances","volume":"4 2","pages":"Article 100561"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11757786/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review article, we aimed to define malnutrition in patients with chronic liver disease (CLD), elucidate the pathogenesis of malnutrition, discuss the advantages and disadvantages of current screening methods, and highlight the latest evidence-based dietary recommendations. Emerging evidence suggests that CLD-specific tools such as the Liver Disease Undernutrition Screening Tool and the Royal Free Hospital-Nutritional Prioritizing Tool can accurately identify patients at high risk for malnutrition and should be used in conjunction with more standard tools such as subjective global assessments. The pathogenesis of malnutrition in CLD is multifactorial but seems to arise in large from altered metabolism, namely a reduction in protein synthesis and an increase in resting energy expenditure. However, decreased nutrient intake, impaired nutrient absorption and increased nutrient losses have also been shown to contribute. Key findings in this review argue against protein-restricted diets in patients with CLD and support the use of plant-based proteins over dairy and meat proteins for those with liver cirrhosis complicated by hepatic encephalopathy. Frequent small meals are recommended in patients with liver cirrhosis in addition to the avoidance of prolonged fasts >12 hours due to their hypercatabolic state. CLD covers a wide spectrum of diseases, and this review calls for an individualized approach to addressing the specific nutritional needs, depending on the etiology of CLD, its severity, associated complications, and comorbid conditions. This can be best achieved by close, longitudinal follow-up with a multidisciplinary team including a registered dietitian who can obtain a comprehensive, accurate nutritional assessment.</div></div>","PeriodicalId":73130,"journal":{"name":"Gastro hep advances","volume":"4 5","pages":"Article 100613"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
