[PMID: 37821256 DOI: 10.1016/j.transproceed.2023.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 06/21/2023] [Accepted: 08/01/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND If chronic allograft nephropathy can be detected early and treated, the long-term survival rate of the transplanted kidney may be effectively improved. PURPOSE To compare the application value of real-time sound touch elastography (STE), strain elastography, and color Doppler flow imaging in evaluating chronic kidney disease of transplanted kidneys. MATERIALS AND METHODS A total of 101 patients with renal transplantation were divided into a normal group (serum creatinine <134 mol/L, 58 patients) and a chronic allograft nephropathy group after renal transplantation over 6 months (serum creatinine >134 mol/L, 43 patients). The maximum elastic modulus (Emax) was determined, and receiver operator characteristics were used to compare the diagnostic efficacy of STE ultrasound. RESULTS Emean, Emax, B/A (the strain rate of the internal oblique muscle tissue/ the strain rate of the central renal cortex) of cortical standard strain ratio in strain elastography, and resistance index (RI) between normal and chronic allograft nephropathy groups have statistical significance (P < .05). Emax is superior to B/A and arcuate artery RI in the chronic cortex in the diagnosis of renal dysfunction, and the area under the receiver operator characteristics curve is 0.88. The estimated glomerular filtration rate was negatively correlated with renal cortex Emax, B/A, and arcuate artery RI, among which Emax was the strongest (r = - 0.713, P < .001). The renal cortical Emax cut-off was 30.95 kPa, the sensitivity was 92%, the specificity was 88%, and the accuracy was 88%. CONCLUSION The STE technique to evaluate chronic renal dysfunction after renal transplantation is more sensitive than traditional strain-type elastography and hemodynamic parameters, with renal function decline, renal cortex Emax, renal cortical B/A, and arcuate artery RI gradually increased, and renal cortex Emax was particularly obvious.

Abstract
The serological diagnostic criteria for the immune-tolerant (IT) phase have not been strictly defined and it is hard to determine an accurate rate for significant histologic changes among IT patients. The aim of this study was to establish a baseline rate of significant histologic changes and to determine the main characteristics of IT patients. We systematically searched PubMed, Embase, and Web of Science. Studies reporting liver biopsy results (inflammation grade or fibrosis stage) for adults with chronic hepatitis B virus (HBV) infection in the IT phase diagnosed by serological criterion were included to pool the rate of significant histologic changes. Studies that enrolled subjects with confirmed chronic HBV infection in the IT phase diagnosed by serological and liver biopsy criteria (dual criteria) were included to pool the mean values of main characteristics among IT patients. Of 319 studies screened, 15 were eventually included in the meta-analysis. The pooled rates of significant liver fibrosis and inflammatory activity for 10 studies were 10% (95% confidence interval [CI] 0.06-0.18) and 16% (95% CI 0.07-0.31), respectively. The pooled mean values of age, alanine aminotransferase level, HBV DNA level, and HBsAg level for another 5 studies with IT patients diagnosed by dual criteria were 30.7 years (95% CI 27.31-34.09), 26.64 IU/mL (95% CI 24.45-28.83), 8.41 log10 cp/mL (95% CI 7.59-9.23), and 4.24 log10 IU/mL (95% CI 3.67-4.82), respectively. Significant histologic changes were not rare events among IT patients. Strictly defined serological diagnostic criteria for the IT phase are warranted.

Abstract
OBJECTIVE We aimed to evaluate the agreement/accuracy of point shear-wave elastography (p-SWE) and 2D-shear-wave elastography (2D-SWE) for liver fibrosis staging using transient elastography (TE) as the reference. METHODS This retrospective study analyzed data from people with chronic liver diseases submitted to TE, p-SWE, and 2D-SWE. Liver fibrosis stages were defined using the TE's 'rule of five': normal (<5 kPa); suggestive of compensated-advanced chronic liver disease (cACLD) (10-15 kPa); highly suggestive of cACLD (15-20 kPa); suggestive of clinically significant portal hypertension (>20 kPa). Agreement and accuracy of p-SWE and 2D-SWE were assessed. Optimal cutoffs for p-SWE and 2D-SWE were identified using the point nearest to the upper left corner of the ROC curves. RESULTS A total of 289 participants were included. The correlation between TE and 2D-SWE (rho = 0.59; P < 0.001) or p-SWE (rho = 0.69; P < 0.001) was satisfactory. The AUROCs (95% CI) of 2D-SWE and p-SWE for TE ≥ 5 kPa; TE ≥ 10 kPa; TE ≥ 15 kPa and TE ≥ 20 kPa were 0.757 (0.685-0.829) and 0.741 (0.676-0.806); 0.819 (0.770-0.868) and 0.870 (0.825-0.915); 0.848 (0.803-0.893) and 0.952 (0.927-0.978); 0.851 (0.806-0.896) and 0.951 (0.920-0.982), respectively. AUROCs of 2D-SWE were significantly lower compared with p-SWE for detecting cACLD. Optimal thresholds of 2D-SWE and p-SWE for TE ≥ 15 kPa were 8.82 kPa (sensitivity = 86% and specificity = 79%) and 8.86 kPa (sensitivity = 90% and specificity = 92%), respectively. CONCLUSION LSM by p-SWE and 2D-SWE techniques were correlated with TE. LSM by p-SWE seems to be more accurate than 2D-SWE to identify patients with more advanced fibrosis.

Abstract
BACKGROUND AND AIMS Chronic hepatitis B virus (CHB) infection remains a major global health burden and the non-invasive and accurate diagnosis of significant liver fibrosis (≥ F2) in CHB patients is clinically very important. This study aimed to assess the potential of the joint use of ultrasound images of liver parenchyma, liver stiffness values, and patients' clinical parameters in a deep learning model to improve the diagnosis of ≥ F2 in CHB patients. METHODS Of 527 CHB patients who underwent US examination, liver elastography and biopsy, 284 eligible patients were included. We developed a deep learning-based data integration network (DI-Net) to fuse the information of ultrasound images of liver parenchyma, liver stiffness values and patients' clinical parameters for diagnosing ≥ F2 in CHB patients. The performance of DI-Net was cross-validated in a main cohort (n = 155) of the included patients and externally validated in an independent cohort (n = 129), with comparisons against single-source data-based models and other non-invasive methods in terms of the area under the receiver-operating-characteristic curve (AUC). RESULTS DI-Net achieved an AUC of 0.943 (95% confidence interval [CI] 0.893-0.973) in the cross-validation, and an AUC of 0.901 (95% CI 0.834-0.945) in the external validation, which were significantly greater than those of the comparative methods (AUC ranges: 0.774-0.877 and 0.741-0.848 for cross- and external validations, respectively, ps < 0.01). CONCLUSION The joint use of ultrasound images of liver parenchyma, liver stiffness values, and patients' clinical parameters in a deep learning model could significantly improve the diagnosis of ≥ F2 in CHB patients.

Abstract
AIM The aim of the study was to demonstrate the liver stiffness (LS) change in chronic hepatitis C (CHC) patients obtained by elastography point quantification technique in before and after antiviral treatment (AVT). MATERIAL AND METHODS This prospective study included 84 patients diagnosed with CHC who had not previously received treatment for CHC and who had an indication for using direct-acting AVT. Necessary measurements were recorded with noninvasive liver fibrosis (LF) examinations. Posttreatment control of patients was carried out (ombitasvir + paritaprevir + ritonavir) + 3 months after the start of treatment for those treated with dasabuvir and 6 months after the start of treatment for patients treated with sofosbuvir + ribavirin. Liver stiffness changed after AVT is accepted as (Δ-LS), LS before AVT-LS after AVT. RESULTS Basal LS was found to decrease significantly after AVT (8.00 ± 2.56 kPa vs 6.95 ± 2.86 kPa, P < 0.05). Similar aspartate aminotransferase-to-platelet ratio index and platelet number fibrosis 4 indices were observed before and after AVT (P > 0.05). It was observed that Δ-LS value after AVT was lower in patients with Child-Pugh class A cirrhosis than patients without cirrhosis (P < 0.05). In the comparison between Δ-LS value after AVT and LF score determined by liver biopsy, it was seen that the greatest Δ-LS value was in patients with fibrosis score of 3. An independent relationship was found between Δ-LS after AVT and LF score determined by biopsy (P < 0.05). CONCLUSIONS The LS value determined by the elastography point quantification technique is more effective than other noninvasive laboratory methods in demonstrating the CHC treatment response in clinical practice.

Abstract
PURPOSE OF REVIEW In 2015, as a consequence of the high development in noninvasive tests, Baveno VI consensus recommended for the first time the use of a prediction rule (liver stiffness <20kPa and platelet count > 150000) to identify patients at low risk of having varices and that could circumvent endoscopy. These became known as the Baveno VI criteria. We review here the data validating Baveno VI criteria and we discuss the attempts of expanding these criteria. RECENT FINDINGS We report 28 studies assessing the performance of Baveno VI criteria showing a pooled 99% negative predictive value for ruling out high-risk varices. Performance is not affected by the cause of cirrhosis. Different attempts at expanding these criteria show suboptimal performance. Nonelastography-based criteria require further validation. SUMMARY Baveno VI criteria can be safely used to avoid endoscopy in a substantial proportion of patients with compensated cirrhosis. The progressive change in approach to the management of compensated cirrhosis, progressively focusing on treating portal hypertension with beta-blockers independently of the presence of varices, might render these criteria less relevant.

Abstract
Chronic viral hepatitis is a major cause of chronic liver disease leading to liver fibrosis. This study aimed to assess the diagnostic performance of elastography point quantification (ElastPQ), transient elastography (TE), and aspartate aminotransferase-to-platelet count ratio index (APRI) for the staging of liver fibrosis in patients with chronic viral hepatitis using histopathological findings as a reference standard. For 122 patients with chronic viral hepatitis, diagnostic performance was evaluated using area under the receiver operating characteristic curve (AUROC) analysis and correlations were determined using Spearman’s correlation coefficient. The AUROC of ElastPQ for the diagnosis of the fibrosis stage ≥ F2 was 0.917 with a cut-off value of 3.935. There was a significant positive correlation between the different stages of histologic liver fibrosis and stiffness values obtained using ElastPQ, TE, and APRI (ρ = 0.556, ρ = 0.657, ρ = 0.375, respectively; p < 0.001). ElastPQ showed a higher diagnostic accuracy than APRI, resembling that of TE; AUROC values of ElastPQ, TE, and APRI were 0.917, 0.964, and 0.896, respectively, for a fibrosis stage ≥ F2. ElastPQ is a promising noninvasive technique with a diagnostic accuracy comparable with that of TE for the evaluation of liver fibrosis in patients with chronic viral hepatitis.

Abstract
Chronic pancreatitis (CP) is pathologically characterized by the loss of exocrine pancreatic parenchyma, irregular fibrosis, cellular infiltration, and ductal abnormalities. Diagnosing CP objectively is difficult because standard diagnostic criteria are insufficient. The change of parenchymal hardness is the key factor for the diagnosis and understanding of the severity of CP. The ultrasonography (US) or endoscopic ultrasonography (EUS) elastography have been used to diagnose pancreatic diseases. Both strain elastography (SE) and shear wave elastography are specific diagnostic techniques for measuring tissue hardness. Most previous studies were conducted with SE. There are three methods of interpreting SE; the method of recognizing the patterns in SE distribution images in the region of interest, the method of using strain ratio to compare the hardness of adipose tissue or connective tissue with that of the lesion, and the method of evaluating the hardness distribution of a target by histogram analysis. These former two methods have been used primarily for neoplastic diseases, and histograms analysis has been used to assess hardness distribution in the evaluation of CP. Since the hardness of the pancreas increases with aging, it is necessary to consider the age in the diagnosis of pancreatic disorders using US or EUS elastography.

Abstract
BACKGROUND AND AIMS To date, no study has explored the potential role of ElastPQ, a novel point-SWE technique, in the assessment of clinically significant portal hypertension. The aim of our study was to determine a liver stiffness (LS) cut-off value measured by ElastPQ and laboratory parameters that could help to identify those patients who can safely avoid screening endoscopy. METHODS Data were collected on 1422 patients who underwent ElastPQ measurement from January 2013 to January 2016 in our Department. Inclusion criteria were a LS value of ≥7 kPa, an upper gastrointestinal endoscopy within 12 months and a diagnosis of compensated chronic liver disease. Exclusion criteria were history of decompensated liver disease, evidence of porto-spleno-mesenteric vein thrombosis and non-cirrhotic portal hypertension. Varices were graded as low-risk varices (grade <2) or varices needing treatment (VNT, grade ≥2). RESULTS The study included 195 patients (120 [61%] HCV, 171 [88%] Child-Pugh A). Varices were present in 35% cases, with 10% prevalence of VNT. According to ROC curve analysis, LS measurement and platelet count were evaluated as predictors of VNT. Overall, 75/195 (38%) met the 'BAVElastPQ' criteria (that is, LS < 12 kPa and platelet count >150 000/μL). Within this group, 11/75 (15%) had any grade of varices and only 1/75 (1%) had VNT. The BAVElastPQ criteria gave sensitivity of 0.95, specificity of 0.42, positive predictive value of 0.15 and negative predictive value of 0.99. CONCLUSIONS The BAVElastPQ criteria correctly identified 99% of patients without VNT. By applying such criteria, we could have potentially avoided 38% of surveillance endoscopies in our cohort.

Abstract
Background & aims: Biopsy is the gold standard for staging liver fibrosis, but it may be accompanied by complications. As an alternative, non-invasive markers such as transient elastography (for liver fibrosis) and certain combinations of routine blood markers (liver function tests, full blood count) have been developed although their clinical significance remains controversial. Here, we compare the diagnostic values of non-invasive markers for liver fibrosis in patients with chronic hepatitis B infection. Methods: Transient elastography and routine laboratory tests were performed in 196 patients. Diagnostic performances were compared and were assessed based on the area under the curve (AUC) of a receiver operating characteristic (ROC) analysis. Results: Elevated GGT to platelet ratio (GPR), the fibrosis index FIB-4 [based on age, AST, platelets and ALT], platelet to lymphocyte ratio (PLR) and total bilirubin were independent predictors of liver stiffness defined by transient elastography (all P < 0.001). The AUCs of GPR in predicting both advanced fibrosis and cirrhosis were significantly larger than that of FIB-4 (P = 0.037 and P = 0.008, respectively) and AST-to-platelet ratio index (APRI) (P = 0.008 and P = 0.005). FIB-4, APRI and red cell volume distribution width-to-platelet ratio (RPR) had similar diagnostic values in discriminating different levels of liver fibrosis. Conclusions: GPR showed the best diagnostic value and RPR and PLR are easily available and inexpensive markers in evaluating fibrosis and cirrhosis. The diagnostic values of these laboratory markers are useful in diagnosing advanced fibrosis or cirrhosis, and in confirming the different levels of liver fibrosis.

Koc AS, Sumbul HE. Renal cortical stiffness obtained by shear wave elastography imaging is increased in patients with type 2 diabetes mellitus without diabetic nephropathy. J Ultrasound 2018; 21:279-285. [PMID: 30051234 DOI: 10.1007/s40477-018-0315-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2018] [Accepted: 07/18/2018] [Indexed: 12/31/2022] Open
Abstract
PURPOSE It is known that patients with type 2 diabetes mellitus (DM) who develop diabetic nephropathy have increased renal cortical stiffness (CS) determined by shear wave elastography (SWE). However, there is no data in the literature to our knowledge related to CS values determined by SWE in type 2 DM patients with normal renal function. In this study, we aimed to investigate the change of renal CS obtained by SWE examination in type 2 DM patients with normal renal function compared to non DM patients. METHODS A total of 103 patients (86 males, 17 females and mean age 63.2 ± 11.8 years) with or without type 2 DM were included in the study. The eGFR value of all patients was > 60 ml/kg/1.732. Routine history, physical examination and laboratory examinations were performed. In addition to routine renal ultrasonography (USG), renal resistive index (RRI), renal pulsatility index (RPI), accelerated time (AT), and CS were measured. RESULTS Fifty patients with type 2 DM and 53 patients without type 2 DM were included in the study. Patients with type 2 DM had higher blood glucose, blood urea nitrogen and HbA1c levels (p < 0.05 each one). Renal length and width and echogenicity were similar between two groups with conventional renal USG. Renal parenchyma thickness was higher in patients with type 2 DM. When the findings of renal Doppler USG were examined, RRI was similar between two groups. RPI and AT were higher in patients with type 2 DM. CS values obtained with renal SWE were significantly higher in patients with type 2 DM (p < 0.05). CONCLUSION Cortical stiffness value obtained by SWE is significantly higher in type 2 DM patients with normal renal function compared to patients without DM. We recommend CS measurement as part of routine screening of nephropathy in patients with type 2 DM and normal renal function to guide management and treatment plan.
