A combination of liver stiffness and international normalized ratio is an ideal prognostic predictor of portosystemic shunt occlusion in patients with portal hypertension. J Gastroenterol 2023; 58:246-256. [PMID: 36583759 DOI: 10.1007/s00535-022-01947-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 12/22/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND We previously reported liver stiffness (LS) as a prognostic predictor of portosystemic shunt (PSS) occlusion. This study aims to reinvestigate the predictive factors of the model for end-stage liver disease-sodium (MELD-Na) score amelioration following balloon-occluded retrograde transvenous obliteration (BRTO) and to evaluate the postoperative prognoses of patients with portal hypertension by using newly identified factors. METHODS Seventy-five patients who underwent BRTO between 2008 and 2021 were retrospectively enrolled. The MELD-Na scores were calculated preoperatively and one month postoperatively. We monitored long-term outcomes and analyzed postoperative survival. RESULTS At one month postoperatively, the MELD-Na score decreased in 46 (61.3%) patients. Univariate analyses revealed a significant association of the score amelioration with nine factors, including lower LS levels and a higher international normalized ratio (INR). A multivariate logistic regression analysis with receiver operating characteristic curve analyses identified preoperative LS levels and INR as significant independent predictors of the postoperative MELD-Na score amelioration, with optimal cutoffs of 28.1 kPa and 1.06, respectively. The combination of LS < 28.1 kPa and INR ≥ 1.06 showed a sensitivity and specificity of 84.8% and 75.9% for the prediction of the score amelioration, respectively. For the propensity score model, we matched 24 patients with similar age, sex, MELD-Na score, and concomitant hepatocellular carcinoma. Kaplan-Meier analysis determined significantly higher cumulative survival rates in patients with LS < 28.1 kPa and INR ≥ 1.06 than in other populations. CONCLUSIONS A combination of LS and INR can predict the MELD-Na score amelioration and prognosis improvement following PSS occlusion.

Direct Differentiation of Human Embryonic Stem Cells to 3D Functional Hepatocyte-like Cells in Alginate Microencapsulation Sphere. Cells 2022; 11:3134. [PMID: 36231094 PMCID: PMC9562699 DOI: 10.3390/cells11193134] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 09/19/2022] [Accepted: 09/30/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND The lack of a stable source of hepatocytes is one of major limitations in hepatocyte transplantation and clinical applications of a bioartificial liver. Human embryonic stem cells (hESCs) with a high degree of self-renewal and totipotency are a potentially limitless source of a variety of cell lineages, including hepatocytes. Many techniques have been developed for effective differentiation of hESCs into functional hepatocyte-like cells. However, the application of hESC-derived hepatocyte-like cells (hESC-Heps) in the clinic has been constrained by the low yield of fully differentiated cells, small-scale culture, difficulties in harvesting, and immunologic graft rejection. To resolve these shortcomings, we developed a novel 3D differentiation system involving alginate-microencapsulated spheres to improve current hepatic differentiation, providing ready-to-use hESC-Heps. METHODS In this study, we used alginate microencapsulation technology to differentiate human embryonic stem cells into hepatocyte-like cells (hESC-Heps). Hepatic markers of hESC-Heps were examined by qPCR and Western blotting, and hepatic functions of hESC-Heps were evaluated by indocyanine-green uptake and release, and ammonia removal. RESULTS The maturity and hepatic functions of the hESC-Heps derived from this 3D system were better than those derived from 2D culture. Hepatocyte-enriched genes, such as HNF4α, AFP, and ALB, were expressed at higher levels in 3D hESC-Heps than in 2D hESC-Heps. 3D hESC-Heps could metabolize indocyanine green and had better capacity to scavenge ammonia. In addition, the 3D sodium alginate hydrogel microspheres could block viral entry into the microspheres, and thus protect hESC-Heps in 3D microspheres from viral infection. CONCLUSION We developed a novel 3D differentiation system for differentiating hESCs into hepatocyte-like cells by using alginate microcapsules.

Screening for portopulmonary hypertension using computed tomography-based measurements of the main pulmonary artery and ascending aorta diameters in patients with portal hypertension. Hepatol Res 2022; 52:255-268. [PMID: 34822208 DOI: 10.1111/hepr.13735] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 11/10/2021] [Accepted: 11/23/2021] [Indexed: 12/12/2022]
Abstract
AIM This study aimed to demonstrate the feasibility of identifying candidates of portopulmonary hypertension (PoPH) from general portal hypertension patients based on chest computed tomography (CT) results. METHODS One hundred and thirty patients with portal hypertension who had undergone interventional radiology therapies at our hospital between August 2011 and July 2021 were included, and preoperative clinical data were collected. Suspicious PoPH was defined as main pulmonary artery diameter (mPA-D) ≥ 29 mm or the ratio of mPA-D to ascending aorta diameter (mPA-D/aAo-D) ≥ 1.0, and probable PoPH as mPA-D ≥ 33 mm based on the chest CT. Prevalence of suspicious and probable PoPH was evaluated, and the differences in clinical characteristics of each population were compared. RESULTS Overall, 29 (22.3%) and 5 (3.8%) patients were categorized as suspicious and probable PoPH, respectively. Univariate analyses revealed that female sex, higher shortest diameter of inferior vena cava, presence of portosystemic shunts ≥ 5 mm, and lower blood urea nitrogen levels were significantly associated with suspicious PoPH (p < 0.05). Multivariate analyses identified all four factors as significantly independent determinants of suspicious PoPH (p < 0.05). In addition, among the population of suspicious PoPH, there were significant differences in seven parameters, including total bilirubin levels and spleen volume between patients with and without probable PoPH (p < 0.05). However, no significant independent indicators of probable PoPH were found. CONCLUSIONS CT-based measurements of mPA-D and mPA-D/aAo-D have the potential to screen patients with suspicious PoPH in clinical practice focused on portal hypertension.

Short-term Effects of Hepatic Arterial Buffer Responses Induced by Partial Splenic Embolization on the Hepatic Function of Patients with Cirrhosis According to the Child-Pugh Classification. Intern Med 2021; 60:1331-1342.

Abstract
Objective This study primarily aimed to investigate the short-term effects of partial splenic embolization (PSE) on the Child-Pugh score and identify predictive factors for changes in the score caused by PSE. The secondary aim was to analyze changes in various parameters at one month postoperatively using these identified factors. Methods Between September 2007 and December 2019, 118 patients with cirrhosis and hypersplenism underwent PSE at our hospital. Testing was conducted preoperatively and at one month after PSE. Results Overall, the Child-Pugh score was not significantly changed postoperatively. The Child-Pugh score before PSE was identified as the strongest independent predictor of ameliorated and deteriorated Child-Pugh scores after PSE. Higher pretreatment Child-Pugh scores were correlated with higher posttreatment amelioration rates of the score. A significant decrease in the portal vein diameter and a significant increase in the common hepatic artery diameter were evident at the same level postoperatively in 64 patients with Child-Pugh class A (group A) and in 54 patients with Child-Pugh class B or C (group B/C) preoperatively. According to Murray's Law, PSE resulted in decreased portal venous flow and increased hepatic arterial flow, suggesting a hepatic arterial buffer response (HABR) induced by the procedure. Despite equivalent splenic infarction rates and similar posttreatment changes in hepatic hemodynamics, PSE significantly increased the Child-Pugh score of group A; however, the procedure significantly decreased the score of group B/C. Conclusion Considering original portal venous-hepatic arterial hemodynamics, PSE is expected to produce HABR-mediated hepatic functional improvements in cirrhosis patients with Child-Pugh class B/C.

Splenic non-infarction volume determines a clinically significant hepatic venous pressure gradient response to partial splenic embolization in patients with cirrhosis and hypersplenism. J Gastroenterol 2021; 56:382-394. [PMID: 33629147 DOI: 10.1007/s00535-021-01762-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Accepted: 01/17/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND This study aimed to investigate changes in the hepatic venous pressure gradient (HVPG) by partial splenic embolization (PSE) and to identify the determinants of a clinically meaningful postoperative HVPG reduction. METHODS Sixty-eight patients with cirrhosis and hypersplenism who underwent PSE at our department between September 2007 and June 2020 were included. The HVPG was evaluated pre- and immediately post-PSE. The patients were divided into three groups according to their preprocedural HVPG: low-HVPG (< 10 mmHg, n = 22), intermediate-HVPG (10 mmHg ≤ HVPG < 16 mmHg, n = 33), and high-HVPG (≥ 16 mmHg, n = 13). RESULTS Overall, PSE significantly reduced HVPG from 12.2 ± 4.0 to 9.4 ± 3.6 mmHg (p < 0.01) with a relative decrease of 22.2 ± 20.4%. In addition, HVPG reductions were 19.4 ± 28.7%, 24.0 ± 15.9%, and 22.5 ± 13.3% in the low-, intermediate-, and high-HVPG groups, respectively, indicating no significant difference in HVPG reduction between the groups. An HVPG decrease of ≥ 20% from the baseline, defined in this study as a clinically significant HVPG response to PSE, was achieved in 55.9% of all patients. Multivariate logistic regression and receiver operating characteristic curve analyses identified splenic non-infarction volume as an independent determinant of a 20% decrease in HVPG (p < 0.05), with a cut-off of 139.2 cm3 (sensitivity, 76.3%; specificity, 60.0%; p < 0.05). CONCLUSIONS The splenic non-infarction volume, namely the residual functional spleen volume, independently determines a clinically significant HVPG response to PSE in patients with cirrhosis and hypersplenism.

Abstract
PURPOSE To evaluate the efficacy and intermediate-term outcome of balloon-occluded retrograde transvenous obliteration (BRTO) for the treatment of hepatic encephalopathy (HE) secondary to portosystemic shunt (PSS) in cirrhotic patients. MATERIALS AND METHODS Institutional review board (IRB) approval was obtained for this study and hospital records of patients who underwent BRTO, from August 2011 to August 2015, were analyzed. Based on the inclusion and exclusion criteria, 39 patients (age, 54.07 ± 9.1 years (37-67 years); 33 males and 6 females) with cirrhosis and spontaneous PSS were included. Clinical and laboratory parameters and HE grade were evaluated in all patients before and after the procedure. RESULTS Forty sessions of BRTO were attempted in 39 patients. Follow-up imaging revealed complete obliteration of the treated PSS in all patients with clinical success in 37 patients (94.9%). The 1-, 2-, 3-, 4-, 5-, 6-, and 7-year HE-free survival rates among responders were 91.7%, 91.7%, 88.8%, 85.5%, 80.8%, 80.8%, and 80.8% respectively and overall survival rates were 89.7%, 82.1%, 76.9%, 74.4%, 74.4%, 64.8%, and 64.8% respectively. Logistic regression highlighted Child-Turcotte-Pugh (CTP) score at 6 months as a positive predictive factor of HE recurrence with a cutoff of ≥ 9. Five patients (12.8%) had fever and leukocytosis and 1 (2.6%) patient developed spontaneous bacterial peritonitis after the procedure. CONCLUSION BRTO is an effective treatment for refractory HE in cirrhotics secondary to large PSS with a few possible complications. KEY POINTS • BRTO is an effective and safe treatment for refractory HE, arising from PSS in cirrhotic patients. • Patients with preserved liver function show better outcome and CTP score is the most important predictor of relapse during follow-up.

Abstract
Variceal hemorrhage may cause high rebleeding and mortality rates. Preventing the first episode of variceal bleeding is mandatory in patients with high-risk esophageal varices (EV). This study aimed to identify factors that predict the recurrence of EV after endoscopic treatment (ET), and to develop a reasonable therapeutic strategy for EV in cirrhosis. From January 2012 to December 2014, 45 patients with cirrhosis and high-risk EV underwent ET, including sclerotherapy and/or ligation. Statistical analyses identified factors associated with the recurrence of EV after ET, and the Kaplan-Meier method determined the cumulative variceal recurrence rates. The 1-, 2-, and 3-year cumulative posttreatment recurrence rates for EV were 13.3%, 29.5%, and 32.2%, respectively. No significant differences were evident between the patients with and without variceal recurrences at 1-year posttreatment. The multivariate regression analyses identified a history of partial splenic embolization (PSE) and the pretreatment Child-Pugh classification as independent predictors of variceal recurrences at 2 years (p < 0.05) and 3 years (p < 0.05) posttreatment. While EV did not recur after ET and splenic artery embolization in cases with Child-Pugh class A, the overall posttreatment variceal recurrence rates were 0% and 66.7% when PSE was performed before and after ET, respectively, in those with Child-Pugh class B or C. Splenic artery embolization significantly reduced the hepatic venous pressure gradient and markedly lowered the Child-Pugh score in 15 patients. Adjunctive PSE and pretreatment Child-Pugh class A could be independently associated with reduced cumulative recurrence rates of EV post-ET. From the perspectives of portal hemodynamics and hepatic function, splenic artery embolization before or after ET could prevent posttreatment variceal recurrence in patients with Child-Pugh class A, and PSE before ET could achieve the long-term eradication of EV following ET in those with Child-Pugh class B or C.

BACKGROUND AND AIM This study aimed to identify predictors of model for end-stage liver disease sodium score reductions and improvements in vital prognoses following portosystemic shunt occlusion in portal hypertension patients. METHODS Seventy cirrhotic patients with major portosystemic shunts and a mean model for end-stage liver disease sodium score of 10.5 underwent balloon-occluded retrograde transvenous obliteration between February 2008 and March 2017. We calculated the scores before and 1 month after shunt occlusion. The long-term outcomes were monitored, and vital prognoses were analyzed. RESULTS The model for end-stage liver disease sodium score did not change significantly 1 month post-balloon-occluded retrograde transvenous obliteration, and the score decreased postoperatively in 31 (44.3%) patients. Univariate analyses showed that decline in the score after portosystemic shunt occlusion was strongly associated with hepatic encephalopathy as a procedural indication, lower liver volumes, and lower liver stiffness levels measured by transient elastography before treatment (P < 0.05). Multivariate logistic regression analysis identified preoperative liver stiffness level as an independent predictor of model for end-stage liver disease sodium score amelioration following balloon-occluded retrograde transvenous obliteration (P < 0.05), and receiver operating characteristic curve analysis determined a liver stiffness cutoff value of 21.6 kPa, with a sensitivity of 76.0% and specificity of 69.6%. The Kaplan-Meier method determined that overall survival rates after treatment in patients with liver stiffness < 21.6 kPa were significantly higher than in patients with liver stiffness ≥ 21.6 kPa (P < 0.05). CONCLUSIONS Liver stiffness measured by transient elastography may predict improvements in model for end-stage liver disease sodium scores and in survival rates after portosystemic shunt occlusion in portal hypertension patients.

Comparison of patients with hepatic encephalopathy and those with gastric varices before and after balloon-occluded retrograde transvenous obliteration. Hepatol Res 2018; 48:1020-1030.

Abstract
AIM To compare the clinical characteristics of patients with hepatic encephalopathy (HE) and those with gastric varices (GV) before and after balloon-occluded retrograde transvenous obliteration (BRTO). METHODS Eighty cirrhotic patients who underwent BRTO, including 42 men and 38 women, and whose mean age was 68 years, comprised the HE (n = 18) and GV (n = 62) groups. The patients' data before and 1 month after BRTO were analyzed. RESULTS Before BRTO, the groups did not differ in their portal flow volume (PFV) or hepatic venous pressure gradient (HVPG). The portal vein (PV) was narrower and the splenic vein (SpV) was wider in the HE group than in the GV group. The SpV flow was hepatofugal in 75.0% of HE patients and hepatopetal in 92.6% of GV patients. The Child-Pugh (CP) score of the HE group was significantly higher than that of the GV group pre-BRTO. After BRTO, the PFV and HVPG increases in the HE group equaled those in the GV group, and the PV dilation was similar in both groups. Conversely, the SpV was significantly contracted for HE patients, but significantly dilated for GV patients. Postoperatively, the SpV flow was hepatopetal in all patients. Compared to that in the GV group, the CP score decreased markedly in the HE group, and no significant increases in complications occurred post-BRTO for HE patients. CONCLUSIONS The HE patients showed distinct portal-splenic hemodynamics before and after BRTO. Balloon-occluded retrograde transvenous obliteration markedly improved hepatic function in the HE group compared with the GV group.
