Project description:To evaluate clinical characteristics and factors associated with survival among liver transplantation (LT) recipients with Budd-Chiari syndrome (BCS), with or without transjugular intrahepatic portosystemic shunt (TIPS), in the post-Model for End-stage Liver Disease era.MethodsWe extracted data from the United Network for Organ Sharing database on all adult (≥18 y old) waitlisted candidates and recipients of LT with BCS in the United States between 2002 and 2019. Multivariable Cox regression was used to determine predictors of mortality and hazard ratios (HRs).ResultsA total of 647 BCS patients were waitlisted between 2002 and 2019. BCS was an indication for LT in 378 (0.2%) of all adult LT recipients during the study period. Of BCS patients who received LT, approximately three-fourths (72.3%) were alive for up to 10 y. We found no significant difference in LT outcomes in BCS patients with or without TIPS. Longer length of hospital stay following LT (HR, 1.32; 95% confidence interval [CI], 1.19-1.47), Black/African American race (HR, 2.24; 95% CI, 1.38-3.64), diabetes (HR, 3.17; 95% CI, 1.62-6.21), donor risk index (HR, 1.44; 95% CI, 1.05-1.99), and lower albumin levels at the time of transplantation (HR, 0.66; 95% CI, 0.50-0.88) were negatively associated with survival after LT. Interestingly, neither the Model for End-stage Liver Disease nor prior TIPS showed a significant association with survival after LT.ConclusionsThese findings demonstrate good comparable survival among TIPS versus no TIPS in LT recipients with BCS. The decision for TIPS versus LT should be individualized on a case-by-case basis.

Project description:To analyse the risk of pregnancy (a prothrombotic state) in patients with Budd-Chiari Syndrome (BCS).Retrospective study of pregnancy in women with known BCS at single center from January 2001 to December 2015.Out of 53 females with BCS, 7 women had 16 pregnancies. Median age at diagnosis of BCS in these women was 25 years (range 21-34 years). At least one causal factor for BCS was identified in 6 women (86%). Six women had undergone radiological decompressive treatment. All patients had anticoagulation. Six fetuses were lost before 20 wk gestation in 2 women. There were 9 deliveries over 32 wk gestation and one delivery at 27 wk. All infants did well. Seven babies were born by emergency caesarean section. There were no cases of thrombosis. Two patients had notable vaginal (PV) bleeding in 3 pregnancies. None of the patients had variceal haemorrhage. Two patients were diagnosed with pulmonary hypertension, one during pregnancy and the other in the post-partum period. There was no maternal mortality.Maternal outcomes in patients with treated BCS are favourable and fetal outcomes beyond 20 wk gestation are good. There has been increased rate of caesarean section. Pulmonary hypertension is an important finding that needs further validation. These patients should be managed in centers experienced in treating high-risk pregnancies.

Project description:Gut microbiota is associated with liver diseases. However, gut microbial characteristics of Budd-Chiari syndrome (B-CS) have not been reported. Here, by MiSeq sequencing, gut microbial alterations were characterized among 37 health controls, 20 liver cirrhosis (LC) patients, 31 initial B-CS patients (B-CS group), 33 stability patients after BCS treatment (stability group) and 23 recurrent patients after BCS treatment (recurrence group). Gut microbial diversity was increased in B-CS versus LC. Bacterial community of B-CS clustered with controls but separated from LC. Operational taxonomic units (OTUs) 421, 502 (Clostridium IV) and 141 (Megasphaera) were unique to B-CS. Genera Escherichia/Shigella and Clostridium XI were decreased in B-CS versus controls. Moreover, nine genera, mainly including Bacteroides and Megamonas, were enriched in B-CS versus LC. Notably, Megamonas could distinguish B-CS from LC with areas under the curve (AUCs) of 0.7904. Microbial function prediction revealed that L-amino acid transport system activity was decreased in B-CS versus both LC and controls. Furthermore, OTUs 27 (Clostridium XI), 137 (Clostridium XIVb) and 40 (Bacteroides) were associated with B-CS stability. Importantly, genus Clostridium XI was enriched in stability group versus both recurrence group and B-CS group. Also, PRPP glutamine biosynthesis was reduced in stability group versus recurrence group, but was enriched in stability group versus B-CS group. In conclusion, specific microbial alterations associated with diagnosis and prognosis were detected in B-CS patients. Correction of gut microbial alterations may be a potential strategy for B-CS prevention and treatment.

Project description:Myeloproliferative neoplasms (MPNs) are the leading cause of Budd-Chiari syndrome (BCS), and the C allele of JAK2 rs4495487 was reported to be an additional candidate locus that contributed to MPNs. In the present study, we examined the role of JAK2 rs4495487 in the etiology and clinical presentation of Chinese BCS patients. 300 primary BCS patients and 311 healthy controls were enrolled to evaluate the association between JAK2 rs4495487 polymorphism and risk of BCS. All subjects were detected for JAK2 rs4495487 by real-time PCR. Results. The JAK2 rs4495487 polymorphism was associated with JAK2 V617F-positive BCS patients compared with controls (P < 0.01). The CC genotype increased the risk of BCS in patients with JAK2 V617F mutation compared with individuals presenting TT genotype (OR = 13.60, 95% CI = 2.04-90.79) and non-CC genotype (OR = 12.00, 95% CI = 2.07-69.52). We also observed a significantly elevated risk of combined-type BCS associated with CC genotype in the recessive model (OR = 4.44, 95% CI = 1.31-15.12). This study provides statistical evidence that the JAK2 rs4495487 polymorphism is susceptibility factor JAK2 V617F positive BCS and combined BCS in China. Further larger studies are required to confirm these findings.

Project description:Budd-Chiari syndrome (BCS) results in sinusoidal congestion and hepatocyte apoptosis, which can further progress to liver fibrosis, cirrhosis, and hepatocellular carcinoma. Endovascular (EV) treatment has been the primary therapeutic method and achieved excellent outcomes. However, whether EV treatment could reverse liver cirrhosis in patients with BCS is still unclear. To investigate the effect of endovascular treatment on liver cirrhosis in patients with Budd-Chiari syndrome, we performed gene expression profiling analysis of the liver from patients with or without EV treatment.

Project description:BackgroundBudd-Chiari syndrome (BCS) results when the outflow of the hepatic vein (HV) is obstructed. BCS patients exhibiting an accessory HV (AHV) that is dilated but obstructed can achieve significant alleviation of liver congestion after undergoing AHV recanalization. This meta-analysis was developed to explore the clinical efficacy of AHV recanalization in patients with BCS.Materials and methodsPubMed, Embase, and Wanfang databases were searched for relevant studies published as of November 2022, and RevMan 5.3 and Stata 12.0 were used for pooled endpoint analyses.ResultsTwelve total studies were identified for analysis. Pooled primary clinical success, re-stenosis, 1- and 5-year primary patency, 1- and 5-year secondary patency, 1-year overall survival (OS), and 5-year OS rates of patients in these studies following AHV recanalization were 96%, 17%, 91%, 75%, 98%, 91%, 97%, and 96%, respectively. Patients also exhibited a significant reduction in AHV pressure after recanalization relative to preoperative levels (P < 0.00001). Endpoints exhibiting significant heterogeneity among these studies included, AHV pressure (I2 = 95%), 1-year primary patency (I2 = 51.2%), and 5-year primary patency (I2 = 62.4%). Relative to HV recanalization, AHV recanalization was related to a lower rate of re-stenosis (P = 0.002) and longer primary patency (P < 0.00001), but was not associated with any improvements in clinical success (P = 0.88) or OS (P = 0.29) relative to HV recanalization.ConclusionsThe present meta-analysis highlights AHV recanalization as an effective means of achieving positive long-term outcomes in patients affected by BCS, potentially achieving better long-term results than those associated with HV recanalization.

Project description:Women during pregnancy or puerperium are likely to develop Budd-Chiari syndrome (BCS). However, the reported prevalence of pregnancy-related BCS varied considerably among studies. Our study aims to systematically review this issue. Overall, 817 papers were initially identified via the PubMed, EMBASE, China National Knowledge Infrastructure, and Chinese Scientific and Technological Journal databases. Twenty of them were eligible. The prevalence of pregnancy-related BCS varied from 0% to 21.5%. The pooled prevalence was 6.8% (95% CI: 3.9-10.5%) in all BCS patients, 6.3% (95% CI: 3.8-9.4%) in primary BCS patients, and 13.1% (95% CI: 7.1-20.7%) in female BCS patients. Among them, one study was carried out in Africa with a prevalence of 10.6%; 14 studies in Asian countries with a pooled prevalence of 7.1% (95% CI: 3.1-12.6%); and 5 studies in European countries with a pooled prevalence of 5.0% (95% CI: 3.1-7.3%). The pooled prevalence was 6.7% (95% CI: 2.6-12.3%) in studies published before 2005 and 7.3% (95% CI: 4.2-12.5%) in those published after 2005. In conclusion, pregnancy is a relatively common risk factor for BCS, but there is a huge variation in the prevalence among studies. Physicians should be aware of pregnancy-related BCS.

Project description:Background & Aims:Hepatobiliary phase (HBP) images can discriminate between benign and malignant liver lesions, but it is unclear if this approach can be used in patients with Budd-Chiari syndrome (BCS). Thus, we aimed to assess the diagnostic utility of HBP images in patients with BCS. Methods:This retrospective study included all patients admitted to our institution with a diagnosis of BCS and focal liver lesions on hepatobiliary contrast agent-enhanced MR imaging (HBCA-MRI) from 2000 to 2019. MR images were reviewed by 2 radiologists blinded to the diagnosis of the lesions. Patient and lesion characteristics were recorded, focusing on HBP imaging features. Results:Twenty-six patients (mean 35 ± 11 years old [13-65]; 21 women [81%] 35 ± 12 years old [13-65]; 5 men [19%] 36 ± 10 years old [19-44]) with 99 benign liver lesions and 12 hepatocellular carcinomas (HCCs) were analyzed. Patients with HCC were significantly older than those with benign lesions (mean 50 ± 10 vs. 33 ± 9 years old, p = 0.003), with higher alpha-fetoprotein (AFP) levels (3/4 [75%] vs. 1/22 [5%] with AFP >15 ng/ml, p <0.001). Homogeneous hypointense signals were identified on HBP in 14 lesions, including 12/12 (100%) HCCs, and 2/99 (2%) benign lesions (p <0.001). Most benign liver lesions showed either peripheral (n = 52/99 [53%]) or homogeneous hyperintensity (n = 23/99 [23%]) on HBP. Lesions with signal hypointensity on HBP in patients with AFP serum levels >15 ng/ml were all HCCs. Conclusion:Most benign lesions showed homogeneous or peripheral hyperintensity on HBP images while all HCCs were homogeneously hypointense. HBP images are helpful to differentiate between benign lesions and HCCs and outperform other sequences. They should be systematically acquired for the characterization of focal lesions in patients with BCS. Lay summary:Hepatobiliary phase imaging is an approach that has recently been shown to discriminate between benign and malignant lesions in the liver. However, it was not known whether this imaging approach could be used effectively in patients with Budd-Chiari syndrome. Herein, we have shown that hepatobiliary phase imaging appears to be useful for differentiating between benign and malignant liver lesions in patients with Budd-Chiari syndrome.

Project description:We investigated the effects of gut microbiota and serum metabolite levels in patients with Budd-Chiari syndrome (B-CS) and their importance for guiding clinical management strategies. In total, 214 B-CS patients (93 untreated and 121 treated) and 41 healthy controls were enrolled. Gut microbiota and serum metabolome were analysed using shotgun metagenomics and liquid chromatography-mass spectrometry. The gut microbiota of the patients showed abundance of Campylobacter and low levels of Saccharomyces, Deinococcus, and Thiomonas (P < 0.05). Thirty metabolites, including taurocholate and (R)-3-hydroxybutyric acid, were identified in the patients (VIP > 1, P < 0.05 and FC > 1.2 or FC < 0.83). Random forest (RF) models showed that serum metabolome could effectively identify B-CS from healthy controls and RF-metabolomics exhibited perfect discrimination (AUC = 100%, 95% CI: 100% – 100%), which was significantly higher than that achieved by RF-metagenomics (AUC = 58.48%, 95% CI: 38.46% – 78.5%). Campylobacter concisus and taurocholate showed significant positive correlation in patients with clinical manifestations (P < 0.05). Actinobacteria levels were significantly higher in untreated patients than in treated patients (P < 0.05). Campylobacter and Veillonella levels were significantly higher in treated patients than in healthy controls (P < 0.05). We identified major alterations in the gut microbiota and serum metabolome of patients with B-CS. Faecal metagenomics- and serum metabolomics-guided management strategies are required for patients with B-CS.

Project description:For management of Budd-Chiari syndrome (BCS), a step-wise therapeutic approach starting with medical treatment, followed by endovascular recanalization, transjugular intrahepatic portosystemic shunt, and finally liver transplantation has been adopted. We retrospectively analyzed 51 patients with symptomatic short segment (≤ 30 mm) hepatic vein (HV)-type BCS who underwent percutaneous transluminal balloon angioplasty (PTBA) with/without stenting to determine the feasibility, clinical effectiveness, and long-term outcomes. The intervention was technically successful in 94.1% of cases (48/51)-32 patients underwent PTBA and 16 patients underwent HV stenting. Procedure-related complications occurred in 14 patients (29.1%). The clinical success rate at 4 weeks was 91.7% (44/48). Nine patients underwent reintervention, six patients due to restenosis/occlusion and three patients with clinical failure. The mean primary patency duration was 64.6 ± 19.9 months (CI, 58.5-70.8; range, 1.2-81.7 months). The cumulative 1-, 2-, and 5-year primary patency rates were 85.4, 74.5, and 58.3%, respectively. The cumulative 1-, 2-, and 5-year secondary patency rates were 93.8, 87.2, and 75%, respectively. The cumulative 1-, 2-, and 5-year survival rates were 97.9, 91.5, and 50%, respectively. Percutaneous transluminal angioplasty with and without stenting is effective and achieves excellent long-term patency and survival rates in patients with symptomatic HV-type BCS. With its lower incidence of re-occlusion and higher clinical success rate, HV angioplasty combined with stenting should be the preferred option especially in patients with segmental HV-type BCS.
