ABSTRACT
Transjugular intrahepatic portosystemic shunt (TIPS) is a medical procedure that has been used to manage variceal bleeding and ascites in patients with cirrhosis. It can prevent further decompensation and improve the survival of high-risk decompensated patients. Recent research indicates that TIPS could increase the possibility of recompensation of decompensated cirrhosis when it is combined with adequate suppression of the causative factor of liver disease. However, the results of the studies have been based on retrospective analysis, and further validation is required by conducting randomized controlled studies. In this context, we highlight the limitations of the current studies and emphasize the issues that must be addressed before TIPS can be recommended as a potential recompensating tool.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. While it was previously believed that men have greater susceptibility to CVD, recent research suggests that women face an increased risk of CVD after the onset of menopause, primarily due to the loss of the protective effects of estrogens. Premature ovarian insufficiency (POI), polycystic ovarian syndrome (PCOS), and gestational factors, such as gestational diabetes mellitus (GDM), recurrent pregnancy loss, preterm delivery, and preeclampsia, are specific reproductive disorders that may contribute to an elevated risk of CVD at earlier ages, i.e., before the onset of menopause. This suggests that women with these conditions should be closely monitored for CVD risk factors even before reaching menopause. Such early intervention may help reduce the incidence of CVD and improve overall cardiovascular health in this population. The precise pathophysiological mechanism underlying the development of CVD in women with menopause, premature POI, PCOS, and gestational factors remains elusive. This review article seeks to elucidate the latest research on the relationship between these conditions and CVD in women, aiming to explore the underlying pathogenic mechanisms contributing to this association.
ABSTRACT
The increasing prevalence of type 2 diabetes mellitus (T2DM) and its microvascular and macrovascular complications necessitate an optimal approach to prevention and management. Medical nutrition therapy serves as the cornerstone of diabetes care, reducing reliance on diabetic medications for glycemic control and mitigating cardiovascular risk. The broadening field of research in the effect of low glycemic index (GI) and/or glycemic load (GL) diets on individuals with T2DM has yielded promising results in the existing literature. Adopting low-GI and GL dietary patterns contributes to minimizing fluctuations in blood glucose levels, thus presenting a good strategy for achieving enhanced glycemic control. Furthermore, the above dietary practices may offer a viable alternative and practical approach to weight management in individuals with T2DM. However, clinical practice guidelines for diabetes dietary management show inconsistency regarding the certainty of evidence supporting the implementation of low-GI/GL nutritional patterns. This review aims to thoroughly evaluate the available data on the effectiveness of low-GI and low-GL diets in managing glycemic control and reducing cardiovascular risk factors.
ABSTRACT
BACKGROUND: Type 2 diabetes mellitus (T2DM) is often complicated by steatotic liver disease, cardiovascular disease (CVD), and extrahepatic cancer. We investigated whether FIB-4, an indicator of liver fibrosis, is associated with a higher risk of CVD and extrahepatic cancer history in T2DM. METHODS: Two hundred and nine of 244 diabetics admitted to our center in one year were included and retrospectively evaluated. RESULTS: One hundred and fifty-two (72.7%) were males and 57 (27.3%) females. The mean age and FIB-4 were 64.3 ± 11 years, and 1.15 ± 0.5, respectively. One hundred and fifty patients (71.8%) had FIB-4 ≤ 1.3, and 59 (28.2%) had FIB-4 > 1.3. A history of CVD was presented in 76 (36.4%) patients, and of extrahepatic cancer in 39 (18.7%). Patients with CVD were significantly older than those without (68.4 ± 8.5 vs. 63.2 ± 11.5 years; p = 0.002), with significantly higher FIB-4 (1.26 ± 0.5 vs. 1.08 ± 0.5; p = 0.012). Patients with cancer were older, with higher FIB-4 compared to those without (68.2 ± 9.5 vs. 64.4 ± 10.9 years; p = 0.098 and 1.37 ± 0.6 vs. 1.1 ± 0.5; p = 0.004, respectively). FIB-4 > 1.3 was associated with a 2.1-fold probability for CVD (χ2 = 5.810; p = 0.025) and 2.7-fold probability for cancer history (χ2 = 7.603; p = 0.01). CONCLUSIONS: FIB-4 ≥ 1.3 is associated with a higher probability of CVD or extrahepatic cancer history. FIB-4 could potentially discriminate patients at risk, justifying stricter surveillance.
ABSTRACT
OBJECTIVES: To systematically review the accuracy of spleen stiffness measurement (SSM) by 2D- Shear Wave Elastography (2D-SWE) in predicting high risk for bleeding varices (HRV) in cirrhotic patients. METHODS: PubMed, Embase, Web of Science, Medline, Cochrane, and Google Scholar databases were searched up to 31/05/2023 for all human studies using 2D-SWE to estimate SSM and endoscopy to detect HRV. Meta-analysis was performed using a generalized linear mixed model. Publication bias was evaluated using the funnel plot asymmetry test. The Area Under the Summarized Receiver Operating Characteristic curve (AUSROC) was estimated using the "mada" package. RESULTS: A total of 13 studies and 1970 patients were included. Of them, 27.8 % had HRV. The pooled sensitivity and polled specificity of SSM in detecting HRV were 90 % (95 %CI:87-92 %) and 68 % (95 %CI:58-77 %), respectively, with an AUSROC at 0.86 (95 %CI:0.82-0.90). The median cutoff value of SSM in detecting HRV was 34.2 kPa. In studies including exclusively HBV cirrhotic patients, SSM's polled sensitivity and specificity in predicting HRV was 88 % (95 %CI:82-92 %) and 73 % (95 %CI:68-78 %), respectively. The AUSROC was 0.84 (95 %CI:0.81-0.87). The number of repeated measurements per patient (<5 or ≥ 5) did not affect the method's capability. Using Aixplorer to evaluate SSM had a higher sensitivity in ruling out HRV than other 2D-SWE devices. CONCLUSIONS: Our meta-analysis supports that SSM by 2D-SWE has a good diagnostic performance for ruling out HRV in cirrhosis.

Chronic hepatitis C virus (HCV) infection is characterized by a variety of extra-hepatic manifestations; peripheral neuropathy (PN) is one of the most common, especially when mixed cryoglobulinemia (MCG) is present. The prevalence and risk factors of HCV-related PN in the absence of MCG are largely unknown. We conducted a prospective, single-center study, examining the prevalence and reversibility of HCV-associated neuropathy in the absence of MCG. Nerve fiber density in the epidermis was evaluated through skin biopsy and electroneurography (ENG) before HCV-treatment initiation and 1 year post sustained virological remission (SVR). Forty HCV-infected individuals (nine HIV co-infected) with no other neuron-harming factors were included; four other HCV mono- and three HIV co-infected individuals were excluded due to presence of diabetes, B12 insufficiency, or neurotoxic drugs. Twelve consecutive controls with no neuron-harming conditions were also recruited; eight more were excluded due to meeting exclusion criteria. Four patients had ENG signs of polyneuropathy (two with HCV mono- and two with HIV co-infection), while seven more (five with HCV mono- and two with HIV co-infection) had signs of mono-neuropathy, leading to PN prevalences of 22.5% and 44% for mono- and co-infection, respectively (p value 0.179). The two patients with HCV mono-infection and polyneuropathy and the one with ulnar nerve damage showed ENG improvement 1 year post SVR. Regarding intraepidermal nerve density, HCV infection, irrespective of HIV co-infection, was correlated with a lower intraepidermal neuron density that improved 1 year post SVR (p value 0.0002 for HCV and 0.0326 for HCV/HIV co-infected patients). PN is common in HCV infection; successful eradication of HCV leads to PN improvement.

Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, constitutes a metabolic disorder frequently associated with obesity and insulin resistance (IR). Furthermore, women with PCOS often suffer from excessive anxiety and depression, elicited by low self-esteem due to obesity, acne, and hirsutism. These mood disorders are commonly associated with food cravings and binge eating. Hypothalamic signaling regulates appetite and satiety, deteriorating excessive food consumption. However, the hypothalamic function is incapable of compensating for surplus food in women with PCOS, leading to the aggravation of obesity and a vicious circle. Hyperandrogenism, IR, the reduced secretion of cholecystokinin postprandially, and leptin resistance defined by leptin receptors' knockout in the hypothalamus have been implicated in the pathogenesis of hypothalamic dysfunction and appetite dysregulation. Diet modifications, exercise, and psychological and medical interventions have been applied to alleviate food disorders, interrupting the vicious circle. Cognitive-behavioral intervention seems to be the mainstay of treatment, while the role of medical agents, such as GLP-1 analogs and naltrexone/bupropion, has emerged.

It is well known that both type 1 and type 2 diabetes mellitus (DM) are related to increased risk for cardiovascular (CV) and chronic kidney disease (CKD). However, besides these prominently presented complications, DM has also been associated with reproductive dysfunctions. It seems that these disorders are met in up to 40% of women with DM and consist of delayed menarche, all types of menstrual disorders, such as amenorrhea, oligomenorrhea, menstrual irregularity, as well as menorrhagia, infertility, characteristics of polycystic ovary syndrome (PCOS) and early (or rarely late) menopause. In type 1 DM (T1DM), insulin treatment, although it has reduced the rates of insulinopenic-induced hypogonadotropic hypogonadism, an entity commonly presented in many women with the disease in the past decades, when it is used in excess it can also promote hyperandrogenism. Regarding type 2 DM (T2DM), insulin resistance (IR) and hyperinsulinemia have mainly been implicated in the pathogenesis of reproductive dysfunctions, as insulin can act as gonadotropin on the theca cells of the ovary and can lead to hyperandrogenism and inhibition of proper ovulation. This review aims to detail the reproductive dysfunctions associated with DM and provide scientific data to enlighten the underlying pathogenetic mechanisms.

Diabetic foot ulcers (DFUs) remain a major cause of morbidity. This narrative mini-review aimed to investigate the potential role of folic acid (FA) in DFUs. Individuals with DFUs exhibit lower levels of FA and lower daily intake, compared to those without DFUs. There is preliminary evidence that FA administration may contribute to improved DFUs healing. In this context, regular evaluation of dietary FA intake may prove important towards reduction or even prevention of DFUs. However, data are still limited and further research is required to enable definitive conclusions and any recommendations.
ABSTRACT
This narrative mini-review discusses vitamin E levels in subjects with diabetic foot ulcers (DFUs). Vitamin E may be reduced in subjects with DFUs, but this finding is inconsistent. Its administration appears to benefit patients with DM, delaying the onset of complications, including DFU. There is also evidence that it may promote DFU healing. Nonetheless, further studies are required to confirm these promising results and estimate vitamin E administration's cost-effectiveness.
ABSTRACT
The liver plays a critical role in several metabolic pathways, including the regulation of glucose and lipid metabolism. Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disease worldwide, is closely associated with insulin resistance (IR) and metabolic syndrome (MetS). Hepatokines, newly discovered proteins secreted by hepatocytes, have been linked to the induction of these metabolic dysregulations. Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, has been associated with NAFLD and IR, while hyperandrogenism additionally appears to be implicated in the pathogenesis of the latter. However, the potential role of hepatokines in the development of metabolic disorders in PCOS has not been fully investigated. Therefore, the aim of this review is to critically appraise the current evidence regarding the interplay of hepatokines with NAFLD, hyperandrogenism, and IR in PCOS.

Background: We estimated the frequency of cirrhotic cardiomyopathy (CCM) using all of the proposed diagnostic criteria, to describe the whole spectrum of cardiac alterations, and to investigate the role of stress in unmasking latent cases of CCM. Methods: Ninety consecutive patients were recruited. CCM was evaluated using the Montreal, the American Society of Echocardiography 2009 criteria, and the 2019 modified criteria of the CCM consortium. A dobutamine stress test was also performed. Results: Left ventricular diastolic dysfunction (LVDD) was identified in 72 (80%), 36 (40%), and 10 (11.1%) patients based on the above criteria, respectively. None of the patients had right ventricular systolic dysfunction, either at rest or after stress. The dobutamine stress test revealed left systolic dysfunction in 4 (4.5%) patients. There was agreement among the 3 criteria that the presence of LVDD was not associated with the severity of liver disease, using Child-Pugh stage. However, patients with Child-B/C had longer QTc intervals (P=0.004), higher levels of brain natriuretic peptide (P=0.016), and greater echocardiographic E/e' ratio (P<0.001) and E/e'(s) (P=0.003), compared to Child-A patients, while a significant correlation was demonstrated between Child-Pugh score and E/e' (P<0.001), or E/e'(s) (P=0.002). Conclusions: The prevalence of LVDD seems to be lower than previously considered. Right ventricular function seems to remain unimpaired. A dobutamine stress uncovered only a small percentage of patients with left systolic dysfunction. Nevertheless, the aggravation of several sonographic variables during stress, particularly in Child-B/C patients, potentially indicates a higher risk for clinical heart failure during stressful invasive interventions.
ABSTRACT
INTRODUCTION: Functional Hypothalamic Amenorrhea (FHA) has been associated with excessive-chronic stress, eating disorders, and weight loss. A common feature is the increased serum cortisol, but its measurement has many limitations. Currently, salivary cortisol (SC) has been proposed as a more sensitive and adequate index. AIM: To investigate the SC alterations through a 24-h period and the possible correlation with the severity of stress in women with FHA. METHODS: Between July 2019 and March 2021, 12 FHA women and 12 healthy controls of comparable age were included. Psychological, eating, and physical abnormalities were evaluated by applying equivalent validated self-questionnaires. RESULTS: No significant differences were found between FHA women and healthy individuals with respect to morning (8:00 am) serum cortisol and ACTH (522.5 ± 162.2 vs 442 ± 138.5 nmol/l; p = 0.204 and 37 ± 44.8 vs 17.4 ± 10.8 pg/ml; p = 0.186, respectively). Women with FHA had statistically significant higher morning SC compared to control subjects (21.8 ± 5.9 nmol/l vs 12.8 ± 3.8 nmol/l; p < 0.001), while no significant differences were found regarding the afternoon (4:00 pm) and midnight (12:00 am) SC. A significant positive correlation was found between morning SC and morning serum cortisol (rho = 0.532; p = 0.007), EAT-26 (rho = 0.527; p = 0.008) and HADS-Anxiety score (rho = 0.471; p = 0.02). Additionally, a significant negative correlation between morning SC and BMI was observed (rho = -0.53; p = 0.009). CONCLUSION: Compared to serum cortisol, SC seems to express better the hypercortisolemic state of women with FHA and correlates well with the underlying contributing factors. Larger studies are needed in order to confirm these results and validate the optimal SC cut-off value associated with the development of FHA.

INTRODUCTION: PCOS is associated with mood/eating disorders. Negative body image due to obesity, acne, hirsutism seems to play significant role, but hormonal derangements are probably implicated. AIM: To investigate the relation between insulin resistance (IR), obesity and hyperandrogenism with mood and eating disorders in women with PCOS. METHODS: Forty-nine (60.5%) PCOS women and 32(39.5%) age- and BMI-matched healthy controls were enrolled. Emotional/food disorders were evaluated by using self-administered questionnaires: Eating Attitudes Test (EAT)-26, Beck Depression Inventory-II (BDI-II), Hamilton anxiety scale (HAS) and Food Craving Questionnaire-Trait (FCQ-T). RESULTS: The two groups had no significant differences regarding age, BMI and HOMA2-IR. PCOS women had significantly higher DHEA-S (p < 0.0001), Δ4Α (p < 0.0001) and Testosterone (p < 0.0001). When the two groups were subclassified according to the BMI, in lean (BMI < 25 kg/m2) or overweight (BMI ≥ 25 kg/m2), no significant differences were found with respect to EAT-26 and HAS. BDI-II was associated with obesity (overweight vs lean PCOS: 20.5 ± 6.4 vs 9.8 ± 3.9; p = 0.037) and hyperandrogenism (overweight PCOS vs overweight controls: 20.5 ± 6.4 vs 14.8 ± 8.1; p < 0.0001; lean PCOS vs overweight controls: 16.7 ± 4.7 vs 14.8 ± 8.1; p = 0.01). Additionally, a significant correlation between BDI-II and DHEA-S (rho = 0.305; p = 0.006), Δ4Α (rho = 0.259; p = 0.02) and Testosterone (rho = 0.328; p = 0.003) was reported. FCQ-T was associated with obesity (overweight PCOS vs lean PCOS: 47.6 ± 9.9 vs 29.3 ± 8.9; p < 0.0001; overweight controls vs lean PCOS: 45.5 ± 15.7 vs 29.3 ± 8.9; p < 0.0001), whereas a correlation between FCQ-T and BMI (rho = 0.593; p = 0.0001), waist circumference (rho = 0.554; p = 0.0001) and HOMA2-IR (rho = 0.328; p = 0.003) was documented. CONCLUSIONS: Obesity and hyperandrogenism increase the risk of depression and food cravings in women with PCOS, leading to a vicious circle of further aggravation of obesity and metabolic syndrome.

Portal hypertension (PH) is a major complication of liver cirrhosis, as it predisposes to the development of serious clinical manifestations such as ascites, hepatic encephalopathy and variceal bleeding, aggravating the prognosis of patients. Hepatic vein pressure gradient (HVPG) is considered the reference method for the estimation of the presence and severity of PH, but this procedure is available only in specialized centers. Alternatively, many non-invasive methods have been proposed in order to substitute HVPG. Among them, liver stiffness measurement (LSM) has been widely used, as it has been shown to correlate well with HVPG, though this relationship seems to weaken in values of HVPG higher than 12 mmHg, the threshold of serious complications development. Several studies supported the use of spleen stiffness measurement (SSM) instead of LSM, anticipating to a more adequate assessment of this advanced stage of PH. The aim of this paper is to critically appraise and summarize the literature about the role of SSM as a predictive tool of liver decompensation and prognosis, highlighting the strengths and the potential limitations of the studies published so far. EXPERT'S OPINION: The utility of SSM in ruling out high risk for bleeding varices in cirrhotic patients has been demonstrated, driving the Baveno VII consensus to encompass SSM in its last recommendations, though its use in patients with non-viral cirrhosis remains to be validated. We believe that in the near future, SSM alone or combined with other tests, will being used not only for sparing upper endoscopies, but also for predicting decompensation and prognosis in advanced compensated cirrhotic patients, regardless of liver disease's etiology. Herein, we present the data that support this consideration, pointing out these issues that should further be investigated in order to elucidate and intensify the value of SSM in the management of patients with liver cirrhosis.

BACKGROUND AND AIM: Liver stiffness measurement (LSM) has been predicting liver decompensation and survival in cirrhotics. The aim of our study was to investigate if spleen stiffness measurement (SSM) by 2D shear-wave elastography could predict better the probability of decompensation and mortality, compared with LSM and other parameters. METHODS: Consecutive cirrhotic patients were recruited between 1/2017 and 12/2021. LSM and SSM were performed at baseline and epidemiological, clinical, and laboratory data were collected. Clinical events were recorded every 3 months. RESULTS: Totally, 177 patients were followed for a mean period of 31 ± 18 months. In Cox regression analysis, only SSM was independently associated with the probability of decompensation (HR: 1.063, 95% CI: 1.009-1.120; P = 0.021), offering an AUROC of 0.710 (P = 0.003) for predicting 1-year liver decompensation (NPV: 81.1% for the cut-off point of 37 kPa). The occurrence of death/liver transplantation was independently associated only with higher SSM (HR: 1.043; 95% CI:1.003-1.084; P = 0.034). The AUROC of SSM for predicting 1-year death/liver transplantation was 0.72 (P = 0.006) (NPV: 95% for the cut-off of 38.8 kPa). The performance of SSM to predict the 1-year death/liver transplantation increased in high-risk patients (CTP: B/C plus MELD >10 plus LSM > 20 kPa), giving an AUROC of 0.80 (P < 0.001). Only 1/26 high-risk patients with SSM < 38.8 kPa died during the first year of follow-up (NPV: 96.4%). CONCLUSIONS: SSM was the only factor independently associated with the probability of decompensation and occurrence of death, showing better diagnostic accuracy for the prediction of 1-year decompensation or death compared with LSM and MELD score.

In cirrhotic patients, non-selective b-blockers (NSBBs) constitute the reference treatment of choice as monotherapy or combined with band ligation for the prevention of first variceal bleeding and rebleeding, respectively. Furthermore, the last Baveno VII guidelines recommended carvedilol, a b-blocker with additional anti-a1 receptor activity, in all compensated cirrhotics with clinically significant portal hypertension, to prevent liver decompensation. Interestingly enough, NSBBs have been reported to have a potentially positive impact on the short-term mortality of patients with acute-on-chronic liver failure. However, concerns remain about the use of b-blockers in the presence of severe complications, such as refractory ascites, hepatorenal syndrome, spontaneous bacterial peritonitis, or established cirrhotic cardiomyopathy. In addition, it has not been verified yet whether carvedilol supersedes all the other NSBBs in every stage of liver disease, even when severe complications have developed. Therefore, this review aims to illustrate recent data regarding the potential role of b-blockers across all stages of liver disease, beyond the primary and secondary prophylaxis of variceal bleeding, and address the authors' proposals on the use of NSBBs concerning the severity of liver disease and the patient's performance status.
ABSTRACT
Hepatocellular carcinoma (HCC) represents an entity of poor prognosis, especially in cases of delayed diagnosis. According to the Barcelona Clinic Liver Cancer (BCLC) staging system, patients in BCLC-A are the most suitable for potentially curative treatments (surgery or radiofrequency ablation), whereas those in BCLC-C should be treated only with systemic treatment, as locoregional interventions are ineffective due to the tumor's extensiveness. For patients in the BCLC-B stage, trans-arterial chemoembolization (TACE) is the reference treatment, but the role of systemic treatment has been constantly increasing. As this group of patients is extremely heterogeneous, a case-by-case therapeutic strategy instead of a one-fits-all treatment is certainly required to achieve adequate results against HCC. The decision of selecting among immune checkpoint inhibitors (ICIs), tyrosine kinase inhibitors (TKIs), TACE, or a combination of them depends on the patient's tumor load, the severity of liver dysfunction, the general performance status, and the presence of concomitant extrahepatic diseases. The objective of this review is to critically appraise the recent data regarding the systemic treatment of BCLC-B HCCs, aiming to emphasize its potential role in the management of these difficult-to-treat patients.
ABSTRACT
BACKGROUND AND AIM: The aim of this study is to evaluate the performance of 2D-shear wave elastography (2D-SWE) in patients with nonalcoholic fatty liver disease (NAFLD) and compare it to transient elastography. METHODS: Over 6 months, 552 patients with NAFLD underwent liver stiffness measurement (LSM) by both 2D-SWE and transient elastography with controlled attenuation parameter (CAP) at the same visit. RESULTS: LSM was not feasible by transient elastography (M/XL probe) in 18 (3.3%) and by 2D-SWE in 26 (4.7%) patients. The median LSM of transient elastography was 5.5 (2.8-75) kPa and of 2D-SWE 6.2 (3.7-46.2) kPa. LSMs by transient elastography and 2D-SWE were correlated regardless of the obesity status (r, 0.774; P < 0.001; r, 0.774; P < 0.001; r, 0.75; P < 0.001 in BMI <25, 25-30 and ≥30 kg/m2 respectively), or the degree of liver steatosis (r = 0.63; P < 0.001 and r = 0.743; P < 0.001 in mild and moderate/severe steatosis, respectively). According to transient elastography, 88 (15.9%) patients were classified with at least severe fibrosis (≥F3) and 55 (10%) with cirrhosis. By using the 2D-SWE, 85 (15.4%) patients had at least severe fibrosis and 52 (9.4%) cirrhosis. The correlation between the two methods was strong in patients with at least severe fibrosis (r, 0.84; P < 0.001) or cirrhosis (r, 0.658; P < 0.001). When transient elastography was used as reference, 2D-SWE showed an excellent accuracy of 98.8 and 99.8% in diagnosing severe fibrosis and cirrhosis, respectively. CONCLUSIONS: In NAFLD, 2D-SWE and transient elastography have comparable feasibility and clinical applicability providing LSMs with strong correlation, even in overweight/obese patients, independently of the severity of liver steatosis and fibrosis. Thus, either of the two methods can be effectively used for the assessment of fibrosis in this setting.

The aim of the study was to investigate the feasibility and correlation of liver stiffness measurements (LSM) between 2D-shear wave elastography (2D-SWE) and transient elastography (TE) in patients with chronic liver disease. Over 4 months, 421 patients with chronic liver disease of any cause underwent LSM by 2D-SWE and TE (M and/or XL probe) and controlled attenuation parameter at the same visit. LSM was not feasible by TE in 16 (3.8%) and by 2D-SWE in 17 (4.0%) patients. Median LSM were 8.9 and 8.7 kPa with TE and 2D-SWE, respectively, having a strong correlation (r = 0.774, p < 0.001) in the total cohort and in any cause of liver disease (r = 0.747-0.806, p < 0.001). There was a strong agreement on diagnosis of severe fibrosis (k-statistic: 0.841, p < 0.001) or cirrhosis (k-statistic: 0.823, p < 0.001). Both methods had increased failure rates in patients with obesity and/or increased waist circumference. Among 104 obese patients, TE was more feasible than 2D-SWE (92.3% vs 85.6%, p < 0.001]. LSM by 2D-SWE are strongly correlated to LSM by TE independently of the etiology of chronic liver disease, stage of fibrosis, degree of liver steatosis, and patients' characteristics. TE with the XL probe may be superior in a minority of obese patients.
