A combination of non-invasive tests for the detection of significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease is not superior to magnetic resonance elastography alone.

OBJECTIVES: The aims of the present study were to investigate a combination of magnetic resonance elastography (MRE) and vibration-controlled transient elastography (VCTE) or MRE and fibrosis score 4 (FIB-4) in the detection of significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). METHODS: Between November 5, 2021, and March 4, 2022, a total of 119 consecutive patients with MASLD were included. Liver stiffness was measured using liver biopsy, MRE, VCTE, and FIB-4. Data were collected from outpatient visit charts. Significant fibrosis was defined as ≥ stage 2 fibrosis. RESULTS: All 119 MASLD patients were Caucasian, and their median age was 55 years. MRE, VCTE, and FIB-4 demonstrated significant accuracy in the detection of significant fibrosis with an area under the ROC curve (AUC) of 0.848 ± 0.036 (p < 0.001), 0.632 ± 0.052 (p = 0.012), and 0.664 ± 0.051 (p = 0.001), respectively. However, the diagnostic performance of MRE was superior compared to that of VCTE (AUC difference: 0.216 ± 0.053, p < 0.001) and FIB-4 (AUC difference: 0.184 ± 0.058, p = 0.001). With logistic regression analysis, it was determined that when compared to MRE alone, a combination of MRE and TE (p = 0.880) or MRE and FIB-4 (p = 0.455) were not superior for detecting significant fibrosis. CONCLUSIONS: MRE alone is an accurate and non-invasive method for the identification of MASLD patients with significant fibrosis. CLINICAL RELEVANCE STATEMENT: Magnetic resonance elastography alone accurately detects significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. KEY POINTS: • In routine clinical practice, several non-invasive biochemical-based biomarkers and imaging methods are widely used to assess liver fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. • Magnetic resonance elastography (MRE) is more accurate than vibration-controlled transient elastography (VCTE) or fibrosis score 4 (FIB-4) for assessing liver fibrosis and identifying significant fibrosis in patients with metabolic dysfunction-associated steatotic liver disease. • The combination of MRE and VCTE or MRE and FIB-4 was not superior to MRE alone.

Management of Biliary Complications in Liver Transplant Recipients with Duct-To-Duct Anastomosis: A Single-Center Experience.

BACKGROUND: The aims of this study were to investigate biliary complications in liver transplant recipients with choledochocholedocho stomy anastomosis, to identify the risk factors for the development of such complications, and to evaluate the success of endoscopic approaches in liver transplant recipients. METHODS: Between January 2013 and May 2021, a total of 238 patients with liver diseases underwent liver transplantation: 174 recipients undergoing choledochocholedochostomy anastomosis were included in the analysis. RESULTS: Their median age was 54.0 years. The median posttransplant follow-up period was 29 months. Hepatitis B virus infection (33%) was the most common indication for liver transplantation. Most patients (87%) received living donor liver transplantation. The overall prevalence of posttransplant biliary complications was 31%. Anastomotic biliary strictures were the most common biliary complications (72%), followed by biliary leakage (13%). The median time between endoscopic retrograde cholangiography and liver transplantation was 4 months, with a mean of 3 ± 1.6 sessions. Endoscopic retrograde cholangiography-guided drainage and balloon dilation with or without stent placement was the most common treatment modalities for recipients with biliary strictures. The overall success rate of endoscopic treatment modalities was 83.3%, with 65% of the recipients exhibiting complete biochemical and endoscopic responses. The response did not differ significantly between living donor liver transplantation and cadaveric donor liver transplant recipients (P > .05). Three recipients required revision surgery for biliary complication repair. Six patients died due to biliary sepsis. CONCLUSION: Biliary stricture and leakages were the most common biliary complications after liver transplantation. Endoscopic treatment was successful in most recipients.

The Impact of Inflammatory Bowel Diseases and Related Medications on COVID-19 Severity and Outcome: A Tertiary Referral Center Experience from Turkey.

BACKGROUND: Coronavirus disease-2019 has become a serious pandemic, and still remains a risk despite vaccines that have been devel- oped. Among inflammatory bowel disease patients old age, inflammatory bowel disease activation, the existence of the comorbid dis- ease, and using steroids are known risk factors for severe coronavirus disease-2019. But there are different data for drugs other than corticosteroids used. The aims of the study are to evaluate the prevalence and risk factors of severe coronavirus disease-2019 and the effect of inflammatory bowel disease drugs on severe coronavirus disease-2019. METHODS: In this study among 1195 inflammatory bowel disease patients, 130 patients who were found to be positive for severe acute respiratory syndrome coronavirus-2 between March 2020 and May 2021 were evaluated. Patients were divided into 3 groups as mild, moderate, and severe coronavirus disease-2019. RESULTS: Among 130 patients, 91 (70%) had mild, 16 (12.3%) had moderate, and 23 (17.7%) had severe coronavirus disease-2019. Being 60 years of age or older (P = .009), having at least 1 comorbid disease (P = .002), and having active inflammatory bowel disease (P = .001) were factors that increased the risk for severe coronavirus disease-2019. The use of mesalazine (P = .35), biologic agents (P = .23), and corticosteroids (P = .42) did not increase the risk of severe coronavirus disease-2019. The use of azathioprine seemed to decrease the risk of severe disease with univariate regression analysis however the significance disappeared with multivariate analysis. CONCLUSION: Older age, active inflammatory bowel disease, and existence of at least 1 comorbid disease are risk factors for severe coro- navirus disease-2019. However, drugs used in inflammatory bowel disease management do not increase the risk of severe coronavirus disease-2019. But due to the small number of patients, it is difficult to reach a definite conclusion about corticosteroids.
