Background and aims: Increases in both the prevalence and severity of metabolic dysfunction-associated steatotic liver disease (MASLD) and obesity are closely related. Type 2 diabetes (T2DM) has been associated with metabolic dysfunction-associated steatohepatitis (MASH)-related cirrhosis and hepatocellular carcinoma. Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist approved for the treatment of T2DM and has an important role in weight loss. Also, it may represent a new therapeutic option for the treatment of MASH in obese diabetic patients. The main outcomes were changes from baseline in liver steatosis and fibrosis at week 24. Material and methods: A total of one hundred eighty-seven patients with T2DM were eligible for this prospective study; ninety-five subjects were treated with oral semaglutide, and ninety-two patients were treated with dapagliflozin as an add-on to metformin. All the subjects were evaluated using Vibration Controlled Transient Elastography (VCTE) from June to December 2022. Results: From our cohort, 54% of the patients were females, with a mean age of 59.92 ± 11.89 years and a mean body mass index (BMI) of 29.53 ± 5.33 kg/m2. Following a six-month medication period, we observed a substantial reduction in anthropometric measurements, including the BMI, waist circumference (WC), and waist-to-hip ratio (WtHr), in both groups. Regarding HbA1c, a notable decrease was observed in the semaglutide group (p < 0.001) when compared to the dapagliflozin group (p = 0.011). In addition, the liver stiffness measurement (LSM) according to VCTE improved significantly in the semaglutide group participants from 8.07 ± 2.90 kPa at baseline to 6.51 ± 3.09 kPa after medication (p < 0.001). Conclusion: The superior metabolic effects of semaglutide, correlated to dapagliflozin, may contribute to a more efficient decrease in hepatic stress and injury, leading to a substantial enhancement of liver function in T2DM patients. Further investigations conducted over an ideal timeframe are necessary to confirm the evidence presented in this study. [ABSTRACT FROM AUTHOR]

Introduction: Alcohol consumption (AC) represents a widespread cause of liver diseases affecting 10–20% of the population. The study aimed to evaluate the relationship between advanced liver fibrosis (ALF) measured by transient elastography (TE), laboratory parameters, and the amount of AC depending on non-modifiable risk factors such as age and gender. Methods: We examined 689 patients with an average age of 49.32 ± 14.31 years, 72.9% males, without liver pathology, who admitted a moderate/high consumption (female ≤ 7 versus > 7 drinks/week; male ≤ 14 versus > 14 drinks/week) for at least five years. The fibrosis level was adjusted according to transaminase levels. Predictive factors were established using univariate regression analysis. Results: ALF (≥F3) was detected in 19.30% of subjects, predominantly males (14.1%) and patients over 55 years (12.5%). Excessive consumption of distilled spirits is associated with ALF in females (OR = 4.5), males (OR = 6.43) and patients over 55 years (OR = 3.73). A particularity highlighted in both genders, regardless of the age group, was the negative correlation between the decrease in the number of platelets, the albumin concentration, and the appearance of AFL. Conclusions: Screening using TE represents an approach for early detection of ALF in asymptomatic populations and the development of a risk stratification scheme. [ABSTRACT FROM AUTHOR]

Although high mortality is associated with liver cirrhosis, patients usually have a good quality of life in the compensated phase, and the disease may progress undiagnosed for many years. Vibration-controlled transient elastography with controlled attenuation parameter is a useful noninvasive tool used to estimate both the severity of fibrosis and steatosis. Hence, we aimed to establish the prevalence of significant liver fibrosis diagnosed by vibration-controlled transient elastography in an apparently healthy population. Between December 2021 and March 2022, we conducted a prospective screening of liver fibrosis in apparently healthy participants from different counties of Northeastern Romania. All subjects' medical history was recorded through a comprehensive questionnaire and underwent a liver stiffness measurement. Participants with abnormal liver stiffness measurement values were further evaluated by laboratory tests to identify the etiology of chronic liver disease. A total of 127 apparently healthy subjects were enrolled, mainly females (59.8%), with a mean age of 56 ± 11 years. Overall, 12.6% of participants were found to have significant to advanced fibrosis, and 5.4% had liver cirrhosis. Among 184 participants with clinically significant fibrosis (= 8.0 kPa), 26.1% had a history of heavy alcohol intake, 22.3% tested positive for hepatitis B and C infection, and 2.1% with other etiologies. The remaining 49.5% participants with clinically significant fibrosis were diagnosed with NAFLD, with a mean controlled attenuation parameter value of 282±34 dB/m. The high prevalence of significant liver fibrosis in the general population of Romania is alarming and should raise awareness among clinicians and public health systems. Vibration-controlled transient elastography has demonstrated its usefulness as a screening tool to identify advanced liver fibrosis in general population and should be used in liver disease prevention strategies.

Background and Aims: Inflammatory bowel diseases (IBD) are frequently associated with extraintestinal manifestations, hepatic injury being of concern in these patients. Current literature reports an increased prevalence of liver steatosis and fibrosis in subjects with IBD and the pathophysiology is yet to be completely understood. The aim of this study was to assess the prevalence of non-alcoholic fatty liver disease (NAFLD) in patients with IBD, as well as to determine the factors that connect these two disorders. Methods: From September 2021 to June 2022, 82 consecutive IBD patients were enrolled from a tertiary care center hospital in Iasi. Vibration-Controlled Transient Elastography with Controlled Attenuation Parameter (CAP) was used to assess the presence of NAFLD, with a cut-off score for CAP of 248 dB/m. Significant liver fibrosis was considered at a cut-off for liver stiffness measurements (LSM) of 7.2 kPa. Results: In total, 82 IBD patients (54.8% men, mean age of 49 ± 13 years) were included, 38 (46.3%) of them being diagnosed with NAFLD, with a mean CAP score of 286 ± 35.4 vs. 203 ± 29.7 in patients with IBD only. Age (β = 0.357, p = 0.021), body mass index (BMI) (β = 0.185, p = 0.048), disease duration (β = 0.297, p = 0.041), C—reactive protein (β = 0.321, p = 0.013), fasting plasma glucose (β = 0.269, p = 0.038), and triglycerides (β = 0.273, p = 0.023) were strongly associated with the presence of liver steatosis. The multivariate analysis showed that older age, BMI, and disease duration were strongly associated with significant liver fibrosis in our group. Conclusions: NAFLD is a multifaced pathology with growing prevalence among IBD patients. Additional studies are needed to completely understand this problem and to create a solid evidence-based framework for more effective preventative and intervention strategies. [ABSTRACT FROM AUTHOR]

Non-alcoholic fatty liver disease (NAFLD) is a common finding among patients with type 2 diabetes mellitus (T2DM). Between NAFLD and T2DM exist a bidirectional relationship. Patients with T2DM are at high risk for NAFLD, and evidence suggests that T2DM is linked to progressive NAFLD and poor liver outcomes. NAFLD promotes the development of T2DM and leads to a substantial increase in the risk of T2DM complications. This study aimed to assess the prevalence of liver steatosis and fibrosis in patients with T2DM from north-eastern Romania by using Vibration-Controlled Transient Elastography (VCTE) with Controlled Attenuation Parameter (CAP), which is a non-invasive method and can assess simultaneously liver steatosis and fibrosis. In total, 424 consecutive patients with T2DM were enrolled and evaluated using VCTE with CAP from January 2020 to January 2022. Clinical and laboratory data were recorded in all patients. For the CAP score, we used the following cut-offs: mild steatosis (S1)—274 dB/m, moderate steatosis (S2)—290 dB/m, and severe steatosis (S3)—302 dB/m. For liver fibrosis, to differentiate between fibrosis stages, the cut-off values were F ≥ 8.2 kPa for significant fibrosis (F2), F ≥ 9.7 kPa for advanced fibrosis (F3), and F ≥ 13.6 kPa for cirrhosis (F4). In total, 380 diabetic patients (72.6%) had liver steatosis (51.3% females, the mean age of 55.22 ± 10.88 years, mean body mass index (BMI) 29.12 ± 5.64 kg/m2). Among them, 26 (8.4%) patients had moderate liver steatosis (S2) and 242 (78.5%) patients had severe hepatic steatosis (S3). According to VCTE measurements, 176 (57.14%) patients had liver fibrosis, 36 (11.7%) of them had advanced fibrosis (F3), and 42 (13.6%) diabetic patients had cirrhosis (F4). Univariate analyses showed that severe steatosis was significantly associated with ferritin (β = 0.223, p = 0.022), total cholesterol (β = 0.159, p = 0.031), and HDL-cholesterol (β = −0.120, p = 0.006). In multivariate analyses, BMI (β = 0.349, p < 0.001), fasting plasma glucose (β = 0.211, p = 0.006), and triglycerides (β = 0.132, p = 0.044) were predictors of S3. Patients with T2DM have a high prevalence of severe steatosis and advanced fibrosis which can lead to the development and progression of complications with high morbidity and mortality rates. Hence, it is necessary to implement screening strategies to prevent advanced liver disease in patients with T2DM. [ABSTRACT FROM AUTHOR]

Non-alcoholic fatty liver disease (NAFLD) has had, over the past few decades, a progressively growing prevalence among the general population all over the world, in parallel with metabolic conditions such as type 2 diabetes mellitus (T2DM), dyslipidemia, and obesity. However, NAFLD is also detected in 10–13% of subjects with a body mass index (BMI) ≤ 25 kg/m² (lean-NAFLD), whose major risk factors remain unknown. In this study, we aimed to characterize the clinical features and associated risk factors of lean-NAFLD in comparison with obese-NAFLD patients. Consecutive patients diagnosed with NAFLD by vibration-controlled transient elastography and controlled attenuation parameter were prospectively enrolled. Biological and clinical data obtained from the participants were stratified according to their BMI in two groups: lean-NAFLD and obese-NAFLD. In total, 331 patients (56.8% males) were included in the final analysis. Most of the subjects were obese-NAFLD (n = 258, 77.9%) and had a higher prevalence of T2DM, dyslipidemia, and components of the metabolic syndrome, together with abnormal biological parameters. Regarding liver stiffness measurements, the proportion of subjects with at least significant fibrosis (≥F2) was approximately twofold higher among obese-NAFLD (43.81%) in comparison with lean-NAFLD patients (23.29%). Moreover, obese individuals had a higher risk for liver fibrosis (OR = 2.6, 95%, CI 1.5–4.42, p < 0.001) than lean individuals. Although associated metabolic conditions and at least significant liver fibrosis were present in approximately one-quarter of the patients, these were more frequent among obese-NAFLD patients. Therefore, individualized screening strategies for NAFLD should be established according to BMI. [ABSTRACT FROM AUTHOR]

Chronic hepatitis C virus (HCV) infection induces hepatic steatosis due to viral and host factors. However, information regarding the effects of direct-acting antivirals (DAAs) therapy on liver steatosis and fibrosis is limited. Vibration-controlled transient elastography (VCTE) with a controlled attenuation parameter (CAP) represents a non-invasive method, which has been used in the last few years for the detection of hepatic steatosis and fibrosis before and at a sustained virological response at 12 weeks (SVR12). The aim of this study was to assess the modifications of liver steatosis and fibrosis in HCV-infected patients who achieved SVR12. Consecutive patients with chronic HCV infection that were treated with DAAs in a tertiary gastroenterology center from Romania were included. Demographics, laboratory data, and VCTE evaluation were recorded in all patients. Patients with previous hepatic decompensation and those who did not achieve SVR were excluded. Two hundred and eighty patients (67.1% females) who achieved SVR12 were included. Regarding the changes in biological parameters, including liver enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), reduced to normal levels at SVR12 compared to the baseline (28.72 ± 24.71 U/L vs. 40.72 ± 27.34 U/L for ALT, p < 0.013 and 27.21 ± 11.15 U/L vs. 33.35 ± 23.37 U/L for AST, p = 0.029). On the contrary, the levels of triglycerides increased significantly from the baseline to SVR12 (124.03 ± 113.49 mg/dL to 153.78 ± 94.53, p = 0.004). Regarding hepatic steatosis by CAP evaluation, at SVR12, 186 (66.4%) of the individuals had a CAP score of ≥248 dB/m, an increase of 4.6% from the baseline. After viral eradication with DAAs, we observed an increase in hepatic steatosis. Hence, a long-term follow-up is mandatory to identify HCV-infected patients with hepatic steatosis post-SVR and the risk factors for more severe outcomes. [ABSTRACT FROM AUTHOR]

Vibration-Controlled Transient Elastography (VCTE) with Controlled Attenuation Parameter (CAP) is a widely used non-invasive technique for concomitant assessment of liver steatosis and fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). We aimed to evaluate the level both of hepatic steatosis and fibrosis as well as the associated risk factors in patients referred to our unit with clinically suspected NAFLD or diagnosed by abdominal ultrasonography. Two hundred four patients were prospectively included in this study and assessed by VCTE with CAP. The final analysis included 181 patients with reliable liver stiffness measurements (LSMs) (53% female, mean age 57.62 ± 11.8 years and BMI 29.48 ± 4.85 kg/m2). According to the cut-off values for steatosis grading, there were 10 (5.5%) patients without steatosis (S0), 30 (16.6%) with mild (S1), 45 (24.9%) moderate (S2), and 96 (53%) severe (S3) steatosis. Based on LSM, there were 73 (40.3%) patients without fibrosis (F0), 42 (23.2%) with mild (F1), 32 (17.7%) significant (F2), 19 (10.5%) advanced (F3) fibrosis, and 15 (8.3%) with cirrhosis (F4). In addition, we found an association between several metabolic components and hepatic steatosis and fibrosis. Thus, in the multivariate analysis, higher BMI, fasting plasma glucose, triglycerides, low-density lipoprotein cholesterol, and serum uric were associated with increased CAP. Furthermore, higher serum uric acid and alpha-fetoprotein together with lower platelets count and albumin levels were associated with increased LSM. The assessment of steatosis and fibrosis using VCTE and CAP should be performed in all patients with suspected or previously diagnosed NAFLD in units with available facilities.

Introduction. Non-alcoholic fatty liver disease (NAFLD) is usually associated with type 2 diabetes mellitus (T2DM). The limited number of NAFLD treatment options is well known. Semaglutide, a GLP-1 receptor agonist approved to treat T2DM, is crucial for obtaining a healthy weight. Additionally, may constitute a cutting-edge therapy option for T2DM patients with NAFLD. In this study, liver steatosis and fibrosis in T2DM patients are measured using vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP). Material and Methods. Fifty-seven consecutive patients with T2DM and NAFLD receiving oral semaglutide were enrolled from September 2022 to February 2023 and evaluated by VCTE with CAP. Clinical and analytical data for every subject were recorded. Oral semaglutide was initiated at a dose of 3 mg once daily and subsequently increased to 7 mg at 4 weeks, and 14 mg at 8 weeks in accordance with the diabetologist's recommendations. Results. VCTE analysis showed that 40 diabetic people (70.2%) had significantly lower CAP levels after 24 weeks compared to baseline. Only 14 (24.5%) diabetic patients experienced a significant decrease in liver fibrosis. Regarding body mass index (BMI), aspartate aminotransferase (AST) and alanine aminotransferase (ALT), have improved significantly compared to the baseline (mean BMI 28.72±5.43 kg/m2 to 25.67 ±6.11 kg/m2, mean AST 58.17 ± 16.33 IU/L to 34.54 ± 13.8 IU/L, mean ALT 63.31 ± 12.66 IU/L to 39.17 ± 14.3 IU/L). The mean hemoglobin A1c (HbA1c) value reduced significantly from baseline to 24 weeks (from 8.9% to 7.4%). A significant correlation existed between changes in CAP values and fasting plasma glucose (p=0.31, p=0.52), as well as AST (p=0.188, p=0.48), and BMI (p=0.274, p=0.44). Nausea and diarrhea were the most often reported side effects. Conclusion. In individuals with T2DM with NAFLD, oral semaglutide therapy has improved glycemic control, liver enzymes, body weight, and liver steatosis. These findings suggest that semaglutide may be useful in the treatment of NAFLD patients, therefore more studies concerning liver fibrosis are necessary. [ABSTRACT FROM AUTHOR]

Background and Aims. Inflammatory bowel diseases (IBD) are caused by a dysregulated immune response in the hosts, favored by genetic susceptibility. In addition to symptoms related to the digestive tract, about 40% of patients with IBD also experience extraintestinal manifestations. Although, non-alcoholic fatty liver disease (NAFLD) has been frequently associated with IBDs, the relationship between these two pathologies remains unclear. The aim of this study was to investigate the prevalence of NAFLD among IBD patients, as well as the factors that connect these two conditions. Material and methods. From January 2022 to November 2022, consecutive IBD patients were enrolled from a tertiary care center hospital in Iasi. Patients' demographic information, clinical characteristics including blood pressure, biological parameters, and anthropometric measurements were collected. Following informed consent, participants underwent a fibroscan evaluation for liver stiffness measurement (LSM) and controlled attenuation parameter (CAP). Results. 93 patients with IBD were enrolled (65,3% men, 55,6% with ulcerative colitis). 45 (48,3%) of them were diagnosed with NAFLD, with a mean CAP score of 283 ± 33.4 vs. 215 ± 23.7 in patients with IBD only. Regarding liver fibrosis, mean LSM value in the NAFLD group was 6.8 ± 1.9 kPa vs. 5.7 ± 2.3 kPa in the non-NALFD group. Subjects with NAFLD exhibited higher body mass indexes than those with IBD only (26.2 vs. 33.1, p<0.05). In addition, the prevalence of diabetes was much greater among this group (27.5% vs. 0%; p=0.0001), as was the prevalence of elevated HbA1c levels in the absence of a diabetes diagnosis (14% vs. 7.35%; p=0.23). They also had a non-significantly higher mean systolic blood pressure and greater incidences of hypertension. Compared to those without NAFLD, the NAFLD cohort had higher rates of diagnosed hypercholesterolaemia, were older with a higher mean disease duration and had a higher nonsignificant level of triglycerides. The 10-year risk of myocardial infarction or death estimated by the Framingham risk scores for hard coronary heart disease was higher in the NAFLD group (2.32% vs. 4.27%, p=0.0024). Conclusions. NAFLD is a multifaceted condition that is becoming more common in IBD patients. Although the present evidences in the literature suggest a small risk for the advance of liver fibrosis, the cardiovascular risk seems to be of a greater interest. Considering the above data, patients with IBD should be evaluated with a multidisciplinary approach. [ABSTRACT FROM AUTHOR]

Background and Aims. Non-alcoholic fatty liver disease (NAFLD) and obesity are independently related to an increased risk for atherosclerotic cardiovascular disease (ASCVD), the primary cause of mortality in NAFLD patients. Even though many subjects with NAFLD are normal weight, it still remains uncertain whether their ASCVD risk is of major importance. The aim of this study is to assess and compare the ASCVD risk between lean and obese patients with NAFLD. Methods. Normal weight and obese patients were evaluated between January 2020 and February 2023 and their data was analyzed. NAFLD was diagnosed by vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP) and the American College of Cardiology/American Heart Association guidelines was used to evaluate the ASCVD risk. Results. In the obese group, 104 (63.8%) patients were diagnosed with NAFLD, compared to 32 (12.3%) in the lean population. In comparison to those with obese NAFLD, subjects with lean NAFLD had significantly higher ASCVD scores (mean 15.3% vs 22.7%, p<0.001). Moreover, subjects with lean NAFLD and significant liver fibrosis had a higher risk of ASCVD events, compared to their obese counterparts (OR, 2.51 vs 1.95, p=0.034). Regarding the presence of the components of the metabolic syndrome, the prevalence of type 2 diabetes mellitus was higher the obese group, while changes in the lipid profile and higher systolic blood pressure were more frequently found in lean subjects. Conclusions: Subjects with lean NAFLD had an ASCVD score that were significantly higher than those with obese NAFLD. In both study groups, the presence of significant liver fibrosis was an essential risk factor associated with an ASCVD event, but the effects were more pronounced in lean individuals.

Introduction. Metabolic syndrome (MS) patients are at increased risk for severe liver fibrosis and nonalcoholic fatty liver disease. However, there aren't any recommendations until this moment for screening MS patients. This study aimed to evaluate the diagnostic precision of non-invasive tests in identifying advanced liver fibrosis (F3) and cirrhosis (F4) in MS patients using vibration-controlled transient elastography (VCTE) as a standard quantification method. Materials and Methods. Between September 2022 to March 2023, we prospectively enrolled MS patients at the Gastroenterology and Hepatology Institute Iasi who had undergone evaluation using noninvasive tests like the aspartate aminotransferase to platelet ratio index (APRI) score, fibrosis-4 (FIB-4) index, and NAFLD fibrosis score (NFS). When compared to liver stiffness measures (LSM), we assessed the specificity, sensitivity, negative predictive value (NPV), and positive predictive value (PPV) for each of these indicators in the identification of at least advanced liver fibrosis (=F3). Results. Of the 116 MS patients included in this study, who had a mean BMI of 27.82±4.62 kg/m2 and at least three metabolic conditions, 69 individuals (59.5%) were females. Using a cut-off of 9.7 kPa, 35 (30.2%) patients had at least advanced fibrosis (=F3) according to LSM measurements. VCTE examinations present a higher correlation with the FIB-4 index (r=0.566), NFS (r=0.585), and APRI score (r=0.624) (p< 0.001). The NPV for the FIB-4 index was the highest (90.38%), followed by the NPV for the NFS score (87.84%). The main result of our research showed that all the biomarkers had reasonably high NPV (>85%) and accuracy (>83%) for predicting advanced liver fibrosis, with moderate specificity (80%) and PPV (75%). Conclusion. To prevent progressive fibrosis in MS patients, the FIB-4 index and NFS score seem to be the most suitable surrogate VCTE biomarkers. It may be necessary to take action and further evaluation of liver fibrosis in a tertiary care center for populations at risk after these non-invasive and affordable screening tests are used in primary care settings.
