Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study. Methods: This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. Results: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4). Conclusions: Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

Non-alcoholic fatty liver disease is currently the most common chronic liver disease, affecting up to 25% of the global population. Simple fatty liver, in which fat is deposited in the liver without fibrosis, has been regarded as a benign disease in the past, but it is now known to be prognostic. In the future, more emphasis should be placed on the quantification of liver fat. Traditionally, fatty liver has been assessed by histological evaluation, which requires an invasive examination; however, technological innovations have made it possible to evaluate fatty liver by non-invasive imaging methods, such as ultrasonography, computed tomography, and magnetic resonance imaging. In addition, quantitative as well as qualitative measurements for the detection of fatty liver have become available. In this review, we summarize the currently used qualitative evaluations of fatty liver and discuss quantitative evaluations that are expected to further develop in the future.
Nonalcoholic Fatty Liver Disease as a Systemic Disease and the Need for Multidisciplinary Care

Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease, and there has been a rapid increase in cases worldwide. NAFLD is rapidly becoming the leading cause of hepatocellular carcinoma and is also associated with an increased risk of cardiovascular disease or exacerbation of other organ diseases, thus posing a significant health problem from both a medical and a socioeconomic perspective. NAFLD is a systemic disease and requires the involvement of numerous medical professionals. Multidisciplinary collaboration, in which different professionals within different specialties come together and work together toward a common goal, supports better patient care by integrating perspectives of multiple experts and facilitating the exchange of opinions. Due to the large number of potential patients, gastroenterologists and hepatologists cannot manage the patients alone, and collaboration between specialists in various fields, including family doctors, dentists, nutritionists, and pharmacists is required for treatment of NAFLD. This review will discuss NAFLD from the perspective of various specialties and introduce multidisciplinary collaboration.

Background/AimsNatural history of chronic intestinal pseudo-obstruction (CIPO), a rare disease characterized by episodes of non-mechanical obstruction, is unclear in adults. This study evaluates the clinical course of CIPO and palliative care needs of patients. MethodsFrom October 2010 to September 2021, 74 patients who underwent cine MRI and had a definitive diagnosis of CIPO were prospectively included. We investigated disease etiology and outcomes, age at onset, nutritional status at consultation (body mass index and serum albumin), hydrogen breath test results, and total parenteral nutrition (TPN) during the disease course. ResultsForty-seven patients (64%) were women, with a mean age of 44 years at onset and 49 years at diagnosis. Primary CIPO was observed in 48 patients (65%). Secondary CIPO was observed in 26 cases (35%), of whom 18 (69%) had scleroderma. The mean body mass index, serum albumin level, and hydrogen breath test positivity rate were 17 kg/m2, 3.8 mg/dL, and 60%, respectively. TPN and invasive decompression therapy were required by 23 (31%) and 18 (24%) patients, respectively. Intestinal sterilization was performed in 51 (69%) patients and was effective in 33 (65%); of these, 28 (85%) were taking metronidazole. Seven (9%) patients used opioids. There were 9 deaths (12%), including 5 (56%) from infection and 2 (22%) from suicide. Of the deaths, 6 (67%) and 4 (44%) underwent TPN management and decompression therapy, respectively. Fifty-one patients (69%) wanted palliative care. ConclusionCIPO is a rare, severe, and under-recognized disease. Standardization of treatment strategies, including palliative care and psychiatric interventions, is desired.
