All patients received a combination of tolvaptan(15 mg/d for 5-14 d) and diuretics(40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B(69.2%), hepatitis C(7.7%) and alcohol-in-duced(23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan.RESULTS: Tolvaptan increased the mean urine excretion volume(1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment(from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis.展开更多

METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity.展开更多

It is caused by an impairment in the renal capacity to eliminate solute-free water and is considered to be related to persistent secretionof vasopressin despite low serum osmolality. This nonosmotic release of vasopressin is mediated by the autonomic nervous system, which senses the underfilling of arterial vascular component. This reduction of effective arterial blood volume is closely related to the development of ascites. Although the short-time effects of vasopressin V2 receptor antagonists(vaptans) on hyponatremia and ascites have been repeatedly reported, their effects on the long-term management of cirrhotic ascites have not been established yet. Considering that their effects on water diuresis and their safety are limited by severe underfilling state of patients, cautious approaches with adequate monitoring are needed to advanced cirrhosis. Proper indication, adequate doses and new possibility of combination therapy should be explored in the future controlled study. As hyponatremia is frequent obstacle to ascites management, judicious combination with low-dose diuretics may decrease the incidence of refractory ascites. Although vaptans show much promise in the treatment of advanced cirrhosis, the problem of high cost should be solved for the future.展开更多

METHODS: We retrospectively enrolled 120 refractory ascites patients between January 1, 2009 and September 31, 2014. Sixty patients were treated with oral TLV at a starting dose of 3.75 mg/d in addition to sodium restriction(> 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-60 mg/d furosemide and 25-50 mg/d spironolactone) and 60 patients with large volume paracentesis in addition to sodium restriction(less than 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-120 mg/d furosemide and 25-150 mg/d spironolactone). Patient demographics and laboratory data, including liver function, were not matched due to the small number of patients. Continuous variables were analyzed by unpaired t-test or paired t-test. Fisher's exact test was applied in cases comparing two nominal variables. We analyzed factors affecting clinical outcomes using receiver operating characteristic curves and multivariate regression analysis. We also used multivariate Cox's proportional hazard regression analysis to elucidate the risk factors that contributed to the increased incidence of ascites.RESULTS: TLV was effective in 38(63.3%) patients. The best cut-off values for urine output and reduced urine osmolality as measures of refractory ascites improvement were > 1800 mL within the first 24 h and > 30%, respectively. Multivariate regression analysis indicated that > 25% reduced urine osmolality [odds ratio(OR) = 20.7; P < 0.01] and positive hepatitis C viral antibodies(OR = 5.93; P = 0.05) were positively correlated with an improvement of refractory ascites, while the total bilirubin level per 1.0 mg/dL(OR = 0.57;P = 0.02) was negatively correlated with improvement. In comparing the TLV group and controls, only the serum sodium level was significantly lower in the TLV group(133 mE q/L vs 136 mE q/L; P = 0.02). However, there were no significant differences in the other parameters between the two groups. The cumulative incidence rate was significantly higher in the control group with a median incidence time of 30 d in the TLV group and 20 d in the control group(P = 0.01). Cox hazard proportional multivariate analysis indicated that the use of TLV(OR = 0.58; P < 0.01), uncontrolled liver neoplasms(OR = 1.92; P < 0.01), total bilirubin level per 1.0 mg/dL(OR = 1.10; P < 0.01), and higher sodium level per 1.0 m Eq/L(OR = 0.94; P < 0.01) were independent factors that contributed to incidence. CONCLUSION: Administration of TLV results in better control of refractory ascites and reduced the incidence of additional invasive procedures or hospitalization compared with conventional ascites treatments.展开更多

It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.展开更多

Earlydiagnosis and timely antibiotic administration have successfully decreased themortality rate to 20%-25%. However, many patients cannot be diagnosed in theearly stages due to the absence of classical SBP symptoms. Early diagnosis ofasymptomatic SBP remains a great challenge in the clinic.AIMTo establish a multivariate predictive model for early diagnosis of asymptomaticSBP using positive microbial cultures from liver cirrhosis patients with ascites.METHODSA total of 98 asymptomatic SBP patients and 98 ascites liver cirrhosis patients withnegative microbial cultures were included in the case and control groups,respectively. Multiple linear stepwise regression analysis was performed toidentify potential indicators for asymptomatic SBP diagnosis. The diagnosticperformance of the model was estimated using the receiver operatingcharacteristic curve.RESULTSPatients in the case group were more likely to have advanced disease stages,cirrhosis related-complications, worsened hematology and ascites, and higher mortality. Based on multivariate analysis, the predictive model was as follows: y (P) = 0.018 + 0.312 × MELD (model of end-stage liver disease) + 0.263 × PMN(ascites polymorphonuclear) + 0.184 × N (blood neutrophil percentage) + 0.233 ×HCC (hepatocellular carcinoma) + 0.189 × renal dysfunction. The area under thecurve value of the established model was 0.872, revealing its high diagnosticpotential. The diagnostic sensitivity was 73.5% (72/98), the specificity was 86.7%(85/98), and the diagnostic efficacy was 80.1%.CONCLUSIONOur predictive model is based on the MELD score, polymorphonuclear cells,blood N, hepatocellular carcinoma, and renal dysfunction. This model mayimprove the early diagnosis of asymptomatic SBP.展开更多

METHODS:Eighty-one patients with liver cirrhosis and consequential portal hypertension had TIPS implantation (bare metal) for either refractory ascites (RA) (n= 27) or variceal bleeding (VB) (n = 54). Endpoints for the study were:technical success, stent occlusion and stent stenosis, rebleeding, RA and mortality. Clinical records of patients were collected and analysed. Baseline characteristics [e.g., age, sex, CHILD score and the model for end-stage liver disease score (MELD score), underlying disease] were retrieved. The Kaplan-Meier method was employed to calculate survival from the time of TIPS implantation and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model. Results were expressed as medians and ranges. Comparisons between groups were performed by using the Mann-Whitney Utest and the χ 2 test as appropriate. RESULTS:No difference could be seen in terms of age, sex, underlying disease or degree of portal pressure gradient (PPG) reduction between the ascites and the bleeding group. The PPG significantly decreased from 23.4 ± 5.3 mmHg (VB) vs 22.1 ± 5.5 mmHg (RA) before TIPS to 11.8 ± 4.0 vs 11.7 ± 4.2 after TIPS implantation (P = 0.001 within each group). There was a tendency towards more patients with stage CHILD A in the bleeding group compared to the ascites group (24 vs 6, P = 0.052). The median survival for the ascites group was 29 mo compared to > 60 mo for the bleeding group (P = 0.009). The number of radiological controls for stent patency was 6.3 for bleeders and 3.8 for ascites patients (P = 0.029). Kaplan-Meier calculation indicated that stent occlusion at first control (P = 0.027), ascites prior to TIPS implantation (P = 0.009), CHILD stage (P = 0.013), MELD score (P = 0.001) and those patients not having undergone liver transplantation (P = 0.024) were significant predictors of survival. In the Cox regression model, stent occlusion (P = 0.022), RA (P = 0.043), CHILD stage (P = 0.015) and MELD score (P = 0.004) turned out to be independent prognostic factors of survival. The anticoagulation management (P = 0.097), the porto-systemic pressure gradient (P= 0.460) and rebleeding episodes (P = 0.765) had no significant effect on the overall survival. CONCLUSION:RA, stent occlusion, initial CHILD stage and MELD score are independent predictors of survival in patients with TIPS, speaking for a close follow-up in these circumstances.展开更多

METHODS: Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol (PEG) 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-α concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay (ELISA) and Greiss reaction method,respectively. RESULTS: The intestinal permeability index wassignif icantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites (0.88 ± 0.12 vs 0.52 ± 0.05 or 0.53 ± 0.03,P < 0.05) and correlated with urine nitrite excretion (r = 0.98). Interestingly,the serum TNF-α concentra-tion was significantly higher in LC without ascites than in control subjects or in LC with ascites (198.9 ± 55.8 pg/mL vs 40.9 ± 12.3 pg/mL or 32.1 ± 13.3 pg/mL,P < 0.05). Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites (1170.9 ± 28.7 μmol/L vs 903.1 ± 55.1 μmol/L or 956.7 ± 47.7 μmol/L,P < 0.05). CONCLUSION: Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites,but the serum TNF-α concentration was not related to LC with ascites.展开更多

HH was defined as pleural effusion in the absence ofcardiopulmonary disease. The primary outcomes were overall and transplant-freesurvival at 12-mo after the index admission. Cox proportional hazards analysiswas used to determine factors associated with the primary outcomes.RESULTSOverall, 84 patients were included (mean age, 58 years) with a mean model forend-stage liver disease score of 29. Management with diuretics alone achievedlong-term resolution of HH in only 12% patients. At least one thoracocentesis wasperformed in 73.8% patients, transjugular intrahepatic portosystemic shuntinsertion in 11.9% patients and 33% patients received liver transplantation within12-mo of index admission. Overall patient survival and transplant-free survival at12 mo were 68% and 41% respectively. At multivariable analysis, current smoking [hazard ratio (HR) = 8.65, 95% confidence interval (CI): 3.43-21.9, P < 0.001) and acute kidneyinjury (AKI) (HR = 2.91, 95%CI: 1.21-6.97, P = 0.017) were associated with a significantly increasedrisk of mortality.CONCLUSIONCirrhotic patients with HH are a challenging population with a poor 12-mo survival despitecurrent treatments. Current smoking and episodes of AKI are potential modifiable factors affectingsurvival. HH is often refractory of diuretic therapy and transplant assessment should beconsidered in all cases.展开更多
文摘BACKGROUND Cirrhosis is a common liver disease,and ascites is one of the common clinical conditions.However,the clinical manifestations of ascites combined with hyponatremia as a high-risk condition and its relationship to patient prognosis have not been fully studied.AIM To explore the clinical manifestations,prognostic factors,and relationships of ascites with hyponatremia in patients with cirrhosis to provide better diagnostic and treatment strategies.METHODS In this study,we retrospectively analyzed the clinical data of 150 patients diagnosed with cirrhosis and ascites between 2017 and 2022.Patients were divided into two groups:ascites combined with hyponatremia group and ascites group.We compared the general characteristics,degree of hyponatremia,complications,treatment,and prognosis between the two groups.RESULTS In the study results,patients in the ascites combined with hyponatremia group showed an older average age(58.2±8.9 years),64.4%were male,and had a significantly longer hospitalization time(12.7±5.3 d).Hyponatremia was more severe in this group,with a mean serum sodium concentration of 128.5±4.3 mmol/L,which was significantly different from the ascites group of 137.6±2.1 mmol/L.Patients with ascites and hyponatremia were more likely to develop hepatic encephalopathy(56.2%vs 39.0%),renal impairment(45.2%vs 28.6%)and infection(37.0%vs 23.4%).Regarding treatment,this group more frequently used diuretics(80.8%vs 62.3%)and salt supplements(60.3%vs 38.9%).Multiple logistic regression analysis identified older age[Odds ratio(OR)=1.06,P=0.025]and male gender(OR=1.72,P=0.020)as risk factors for hyponatremia combined with ascites.Overall,patients with ascites and hyponatremia present a clear high-risk status,accompanied by severe complications and poor prognosis.CONCLUSION In patients with cirrhosis,ascites with hyponatremia is a high-risk condition that is often associated with severe complications.
文摘BACKGROUND The lymphatic system is crucial in maintaining the body fluid homeostasis.A dysfunctional lymphatic system may contribute to the refractoriness of ascites and edema in cirrhosis patients.Therefore,assessment of lymphatic dysfunction in cirrhosis patients with refractory ascites(RA)can be crucial as it would call for using different strategies for fluid mobilization.AIM To assessing the magnitude,spectrum,and clinical associations of lymphatic dysfunction in liver cirrhosis patients with RA.METHODS This observational study included 155 consecutive cirrhosis patients with RA.The presence of clinical signs of lymphedema,such as peau d’orange appearance and positive Stemmer sign,intestinal lymphangiectasia(IL)on duodenal biopsy seen as dilated vessels in the lamina propria with strong D2-40 immunohistochemistry,and chylous ascites were used to diagnose the overt lymphatic dysfunctions.RESULTS A total of 69(44.5%)patients out of 155 had evidence of lymphatic dysfunction.Peripheral lymphedema,found in 52(33.5%)patients,was the most common manifestation,followed by IL in 42(27.0%)patients,and chylous ascites in 2(1.9%)patients.Compared to patients without lymphedema,those with lymphedema had higher mean age,median model for end-stage liver disease scores,mean body mass index,mean ascitic fluid triglyceride levels,and proportion of patients with hypoproteinemia(serum total protein<5 g/dL)and lymphocytopenia(<15%of total leukocyte count).Patients with IL also had a higher prevalence of lymphocytopenia and hypoproteinemia(28.6%vs.9.1%,P=0.004).Seven(13%)patients with lymphedema had lower limb cellulitis compared to none in those without it.On multivariate regression analysis,factors independently associated with lymphatic dysfunction included obesity[odds ratio(OR):4.2,95%confidence intervals(95%CI):1.1–15.2,P=0.027],lymphocytopenia[OR:6.2,95%CI:2.9–13.2,P<0.001],and hypoproteinemia[OR:3.7,95%CI:1.5–8.82,P=0.003].CONCLUSION Lymphatic dysfunction is common in cirrhosis patients with RA.Significant indicators of its presence include hypoproteinemia and lymphocytopenia,which are likely due to the loss of lymphatic fluid from the circulation.Future efforts to mobilize fluid in these patients should focus on methods to improve lymphatic drainage.

文摘AIM: To evaluate the efficacy and safety of tolvaptan to treat refractory ascites in decompensated liver cirrhosis patients with or without further complications, such as hepatorenal syndrome and/or hepatocellular carcinoma.METHODS: Thirty-nine patients(mean age 55 years, males: 32) with decompensated liver cirrhosis and refractory ascites were enrolled. All patients received a combination of tolvaptan(15 mg/d for 5-14 d) and diuretics(40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B(69.2%), hepatitis C(7.7%) and alcohol-in-duced(23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan.RESULTS: Tolvaptan increased the mean urine excretion volume(1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment(from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis.
文摘BACKGROUND Individuals with refractory ascites in the context of liver cirrhosis typically face an adverse prognosis.The transjugular intrahepatic portosystemic shunt(TIPS)is an efficacious intervention,but there is a lack of reliable tools for postoperative pro-gnosis assessment.Previously utilized clinical biochemical markers,such as the serum albumin concentration(Alb),sodium(Na+)concentration,and serum creatinine(Scr),have limited predictive value.Therefore,the quest for novel,specific biomarkers to evaluate the post-TIPS prognosis in patients with liver cirrhosis and refractory ascites holds significant practical importance.A retrospective analysis was conducted on 75 patients with liver cirrhosis and refractory ascites who underwent TIPS at our institution from August 2019 to August 2021.These patients were followed up regularly for two years,and the death toll was meticulously documented.The patients were allocated into a survival group(n=45 patients)or a deceased group(n=30 patients)based on their prognosis status.The clinical data of the two groups were collected,and Child-Pugh scores and MELD scores were calculated for analysis.Spearman correlation analysis was carried out to evaluate the correlation of prognosis with Child-Pugh grade,MELD score,and Cys C level.Additionally,a multiple-factor analysis utilizing the Cox proportional hazard model was used to identify independent risk factors affecting the post-TIPS prognosis of patients with liver cirrhosis and refractory ascites.The receiver operating characteristic curve(ROC)ascertained the predictive value of the Cys C concen-tration,Child-Pugh grade,and MELD score for the prognosis of liver cirrhosis with refractory ascites in post-TIPS patients.RESULTS During a 2-year follow-up period,among 75 patients with liver cirrhosis and refractory ascites who underwent TIPS treatment,30 patients(40.00%)passed away.The deceased cohort exhibited heightened aspartate aminotrans-ferase,alanine aminotransferase,total bilirubin,Scr,prothrombin time,Cys C,international normalized ratio,Child-Pugh,and MELD scores compared to those of the survival cohort,while Alb and Na+levels were attenuated in the deceased group(P<0.05).Spearman analysis revealed moderate to high positive correlations between prognosis and Child-Pugh score,MELD score,and Cys C level(r=0.709,0.749,0.671,P<0.05).Multivariate analysis using the Cox proportional hazard model demonstrated that the independent risk factors for post-TIPS prognosis in patients with liver cirrhosis and refractory ascites were Cys C(HR=3.802;95%CI:1.313-11.015),Child-Pugh(HR=3.030;95%CI:1.858-4.943),and MELD(HR=1.222;95%CI:1.073-1.393)scores.ROC analysis confirmed that,compared to those of the classic prognostic models for Child-Pugh and MELD scores,the predictive accuracy of Cys C for post-TIPS prognosis in patients with liver cirrhosis and refractory ascites was slightly lower.This analysis yielded sensitivity and specificity values of 83.33%and 82.22%,respectively.The area under the curve value at this juncture was 0.883,with an optimal cutoff value set at 1.95 mg/L.CONCLUSION Monitoring the serum Cys C concentration is valuable for assessing the post-TIPS prognosis in patients with liver cirrhosis and refractory ascites.Predictive models based on serum Cys C levels,as opposed to Scr levels,are more beneficial for evaluating the condition and prognosis of patients with ascites due to cirrhosis.

文摘BACKGROUND Chylous ascites is caused by disruption of the lymphatic system,which is characterized by the accumulation of a turbid fluid containing high levels of triglycerides within the abdominal cavity.The two most common causes are cirrhosis and tuberculosis,and colon signer ring cell carcinoma(SRCC)due to the use of immunosuppressants is extremely rare in cirrhotic patients after liver transplantation,making it prone to misdiagnosis and missed diagnosis.CASE SUMMARY A 52-year-old man who underwent liver transplantation and was administered with immunosuppressants for 8 months was admitted with a 3-month history of progressive abdominal distention.Initially,based on lymphoscintigraphy and lymphangiography,lymphatic obstruction was considered,and cystellar chyli decompression with band lysis and external membrane stripping of the lymphatic duct was performed.However,his abdominal distention was persistent without resolution.Abdominal paracentesis revealed allogenic cells in the ascites,and immunohistochemistry analysis revealed adenocarcinoma cells with phenotypic features suggestive of a gastrointestinal origin.Gastrointestinal endoscopy was performed,and biopsy showed atypical signet ring cells in the ileocecal valve.The patient eventually died after a three-month follow-up due to progression of the tumor.CONCLUSION Colon SRCC,caused by immunosuppressants,is an unusual but un-neglected cause of chylous ascites.
文摘AIM: To measure plasma D-dimer levels in cirrhotic patients with and without ascites, assessing the effect of ascites resolution in D-dimer concentration. METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity.
文摘BACKGROUND Refractory ascites is a rare complication following orthotopic liver transplantation(OLT).The broad spectrum of differential diagnosis often leads to delay in diagnosis.Therapy depends on recognition and treatment of the underlying cause.Constrictive pericarditis is a condition characterized by clinical signs of right-sided heart failure.In the advanced stages of the disease,hepatic congestion leads to formation of ascites.In patients after OLT,cardiac etiology of ascites is easily overlooked and it requires a high degree of clinical suspicion.CASE SUMMARY We report a case of a 55-year-old man who presented with a refractory ascites three months after liver transplantation for alcoholic cirrhosis.Prior to transplantation the patient had a minimal amount of ascites.The transplant procedure and the early postoperative course were uneventful.Standard posttransplant work up failed to reveal any typical cause of refractory post-transplant ascites.The function of the graft was good.Apart from atrial fibrillation,cardiac status was normal.Eighteen months post transplantation the patient developed dyspnea and severe fatigue with peripheral edema.Ascites was still prominent.The presenting signs of right-sided heart failure were highly suggestive of cardiac etiology.Diagnostic paracentesis was suggestive of cardiac ascites,and further cardiac evaluation showed typical signs of constrictive pericarditis.Pericardiectomy was performed followed by complete resolution of ascites.On the follow-up the patient remained symptom-free with no signs of recurrent ascites and with normal function of the liver graft.CONCLUSION Refractory ascites following liver transplantation is a rare complication with many possible causes.Broad differential diagnosis needs to be considered.
文摘The objective of this study was to investigate the clinical effect of combination treatment of Chinese medicine Baogan Lishui decoction and western medicine on hepatitis B(Hep B)cirrhosis-related refractory ascites.The control group was given conventional western medicine therapy while the observation group was given same conventional western medicine therapy with additional of Chinese medicine Baogan Lishui decoction.The total effective of clinical treatment on Hep B cirrhosis-related refractory ascites in observation group was higher than that of the control group which was 88.89%compared to 71.11%,respectively,and it was significant different(P<0.05).The combination treatment of Chinese medicine Baogan Lishui decoction and conventional western medicine can significantly increase the treatment effect on Hep B cirrhosis refractory ascites,and thus increases the quality and safety of life.

文摘BACKGROUND Rifaximin has been shown to reduce the incidence of hepatic encephalopathy and other complications in patients with cirrhosis.However,few studies have investigated the effect of rifaximin in cirrhotic patients with refractory ascites.AIM To evaluate the effects of rifaximin in the treatment of refractory ascites and to preliminarily explore its possible mechanism.METHODS A total of 75 cirrhotic patients with refractory ascites were enrolled in the study(50 in a rifaximin and 25 in a control group).Patients in the rifaximin group were divided into two subgroups according to the presence of spontaneous bacterial peritonitis and treatment with or without other antibiotics(19 patients treated with rifaximin and 31 patients treated with rifaximin plus intravenous antibiotics).All patients received conventional treatment for refractory ascites,while patients in the rifaximin group received oral rifaximin-α200 mg four times daily for at least 2 wk.The ascites grade,fasting weight,liver and kidney function,and inflammatory factors in the plasma were evaluated before and after treatment.In addition,the gut microbiota was determined by metagenomics sequencing to analyse the changes in the characteristics of the gut microbiota before and after rifaximin treatment.The patients were followed for 6 mo.RESULTS Compared with the control group,the fasting weight of patients significantly decreased and the ascites significantly subsided after treatment with rifaximin(P=0.011 and 0.009,respectively).The 6-mo survival rate of patients in the rifaximin group was significantly higher than that in the control group(P=0.048).The concentration of interferon-inducible protein 10 decreased significantly in the rifaximin group compared with that in the control group(P=0.024).The abundance of Roseburia,Haemophilus,and Prevotella was significantly reduced after rifaximin treatment,while the abundance of Lachnospiraceae_noname,Subdoligranulum,and Dorea decreased and the abundance of Coprobacillus increased after treatment with rifaximin plus intravenous antibiotics.The gene expression of virulence factors was significantly reduced after treatment in both subgroups treated with rifaximin or rifaximin plus intravenous antibiotics.CONCLUSION Rifaximin mitigates ascites and improves survival of cirrhotic patients with refractory ascites.A possible mechanism is that rifaximin regulates the structure and function of intestinal bacteria,thus improving the systemic inflammatory state.
文摘Hyponatremia is a frequent complication of advanced cirrhosis with ascites associated with increased morbidity and mortality. It is caused by an impairment in the renal capacity to eliminate solute-free water and is considered to be related to persistent secretionof vasopressin despite low serum osmolality. This nonosmotic release of vasopressin is mediated by the autonomic nervous system, which senses the underfilling of arterial vascular component. This reduction of effective arterial blood volume is closely related to the development of ascites. Although the short-time effects of vasopressin V2 receptor antagonists(vaptans) on hyponatremia and ascites have been repeatedly reported, their effects on the long-term management of cirrhotic ascites have not been established yet. Considering that their effects on water diuresis and their safety are limited by severe underfilling state of patients, cautious approaches with adequate monitoring are needed to advanced cirrhosis. Proper indication, adequate doses and new possibility of combination therapy should be explored in the future controlled study. As hyponatremia is frequent obstacle to ascites management, judicious combination with low-dose diuretics may decrease the incidence of refractory ascites. Although vaptans show much promise in the treatment of advanced cirrhosis, the problem of high cost should be solved for the future.
文摘BACKGROUND Proton pump inhibitors(PPIs)are widely prescribed,often without clear indications.There are conflicting data on its association with mortality risk and hepatic decompensation in cirrhotic patients.Furthermore,PPI users and PPI exposure in some studies have been poorly defined with many confounding factors.AIM To examine if PPI use increases mortality and hepatic decompensation and the impact of cumulative PPI dose exposure.METHODS Data from patients with decompensated liver cirrhosis were extracted from a hospital database between 2013 to 2017.PPI users were defined as cumulative defined daily dose(cDDD)≥28 within a landmark period,after hospitalisation for hepatic decompensation.Cox regression analysis for comparison was done after propensity score adjustment.Further risk of hepatic decompensation was analysed by Poisson regression.RESULTS Among 295 decompensated cirrhosis patients,238 were PPI users and 57 were non-users.PPI users had higher mortality compared to non-users[adjusted HR=2.10,(1.20-3.67);P=0.009].Longer PPI use with cDDD>90 was associated with higher mortality,compared to non-users[aHR=2.27,(1.10-5.14);P=0.038].PPI users had a higher incidence of hospitalization for hepatic decompensation[aRR=1.61,(1.30-2.11);P<0.001].CONCLUSION PPI use in decompensated cirrhosis is associated with increased risk of mortality and hepatic decompensation.Longer PPI exposure with cDDD>90 increases the risk of mortality.
文摘AIM: To elucidate the efficacies of tolvaptan(TLV) as a treatment for refractory ascites compared with conventional treatment. METHODS: We retrospectively enrolled 120 refractory ascites patients between January 1, 2009 and September 31, 2014. Sixty patients were treated with oral TLV at a starting dose of 3.75 mg/d in addition to sodium restriction(> 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-60 mg/d furosemide and 25-50 mg/d spironolactone) and 60 patients with large volume paracentesis in addition to sodium restriction(less than 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-120 mg/d furosemide and 25-150 mg/d spironolactone). Patient demographics and laboratory data, including liver function, were not matched due to the small number of patients. Continuous variables were analyzed by unpaired t-test or paired t-test. Fisher's exact test was applied in cases comparing two nominal variables. We analyzed factors affecting clinical outcomes using receiver operating characteristic curves and multivariate regression analysis. We also used multivariate Cox's proportional hazard regression analysis to elucidate the risk factors that contributed to the increased incidence of ascites.RESULTS: TLV was effective in 38(63.3%) patients. The best cut-off values for urine output and reduced urine osmolality as measures of refractory ascites improvement were > 1800 mL within the first 24 h and > 30%, respectively. Multivariate regression analysis indicated that > 25% reduced urine osmolality [odds ratio(OR) = 20.7; P < 0.01] and positive hepatitis C viral antibodies(OR = 5.93; P = 0.05) were positively correlated with an improvement of refractory ascites, while the total bilirubin level per 1.0 mg/dL(OR = 0.57;P = 0.02) was negatively correlated with improvement. In comparing the TLV group and controls, only the serum sodium level was significantly lower in the TLV group(133 mE q/L vs 136 mE q/L; P = 0.02). However, there were no significant differences in the other parameters between the two groups. The cumulative incidence rate was significantly higher in the control group with a median incidence time of 30 d in the TLV group and 20 d in the control group(P = 0.01). Cox hazard proportional multivariate analysis indicated that the use of TLV(OR = 0.58; P < 0.01), uncontrolled liver neoplasms(OR = 1.92; P < 0.01), total bilirubin level per 1.0 mg/dL(OR = 1.10; P < 0.01), and higher sodium level per 1.0 m Eq/L(OR = 0.94; P < 0.01) were independent factors that contributed to incidence. CONCLUSION: Administration of TLV results in better control of refractory ascites and reduced the incidence of additional invasive procedures or hospitalization compared with conventional ascites treatments.
文摘Ascites is one of the major complications of liver cirrhosis and is associated with a poor prognosis. It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.

文摘BACKGROUNDSpontaneous bacterial peritonitis (SBP) is a detrimental infection of the asciticfluid in liver cirrhosis patients, with high mortality and morbidity. Earlydiagnosis and timely antibiotic administration have successfully decreased themortality rate to 20%-25%. However, many patients cannot be diagnosed in theearly stages due to the absence of classical SBP symptoms. Early diagnosis ofasymptomatic SBP remains a great challenge in the clinic.AIMTo establish a multivariate predictive model for early diagnosis of asymptomaticSBP using positive microbial cultures from liver cirrhosis patients with ascites.METHODSA total of 98 asymptomatic SBP patients and 98 ascites liver cirrhosis patients withnegative microbial cultures were included in the case and control groups,respectively. Multiple linear stepwise regression analysis was performed toidentify potential indicators for asymptomatic SBP diagnosis. The diagnosticperformance of the model was estimated using the receiver operatingcharacteristic curve.RESULTSPatients in the case group were more likely to have advanced disease stages,cirrhosis related-complications, worsened hematology and ascites, and higher mortality. Based on multivariate analysis, the predictive model was as follows: y (P) = 0.018 + 0.312 × MELD (model of end-stage liver disease) + 0.263 × PMN(ascites polymorphonuclear) + 0.184 × N (blood neutrophil percentage) + 0.233 ×HCC (hepatocellular carcinoma) + 0.189 × renal dysfunction. The area under thecurve value of the established model was 0.872, revealing its high diagnosticpotential. The diagnostic sensitivity was 73.5% (72/98), the specificity was 86.7%(85/98), and the diagnostic efficacy was 80.1%.CONCLUSIONOur predictive model is based on the MELD score, polymorphonuclear cells,blood N, hepatocellular carcinoma, and renal dysfunction. This model mayimprove the early diagnosis of asymptomatic SBP.
文摘Objective:Ascites in patients with hepatic cirrhosis is caused by cirrhosis in most cases.For most malignant ascites,the primary malignancy could be readily identified using conventional imaging methods,e.g.,computer tomography (CT) and magnetic resonance imaging (MRI).However,in a small fraction of the patients,the primary malignancy remains occult even with these examinations.In this retrospective study,we assessed the usefulness of 18F-FDG PET/CT in patients with hepatic cirrhosis and malignant ascites of otherwise unknown origin.Methods:Twenty-eight patients with malignant ascites of unknown primary sites after CT,MRI and ultrasound during the period of five years between January 2008 and December 2012 had received 18F-FDG PET/CT.Medical records of these patients were reviewed and analyzed.Results:Elevated 18F-FDG absorption was found in 23 of 28 cases in the following sites:gastrointestinal tract (n=10,43.5%),prostate (n=5,21.7%),peritoneum (n=4,13.3%),and ovary (n=4,13.3%).Cancer was confirmed by pathology in 20 cases after open or laparoscopic surgeries.Five patients were found to have benign ascites,among which,3 were found to be false positive due to tuberculosis.SUV values were significantly higher for tumors than for benign lesions (mean values,6.95 vs.2.94; P=0.005).Conclusions:The 18F-FDG PET/CT can be as a powerful imaging tool in identifying tissue origin in liver cirrhosis patients suspected of cancers or with cancers of unknown primary sites.

文摘AIM:To determine the clinical outcome and predictors of survival after transjugular intrahepatic portosystemic stent shunt (TIPS) implantation in cirrhotic patients. METHODS:Eighty-one patients with liver cirrhosis and consequential portal hypertension had TIPS implantation (bare metal) for either refractory ascites (RA) (n= 27) or variceal bleeding (VB) (n = 54). Endpoints for the study were:technical success, stent occlusion and stent stenosis, rebleeding, RA and mortality. Clinical records of patients were collected and analysed. Baseline characteristics [e.g., age, sex, CHILD score and the model for end-stage liver disease score (MELD score), underlying disease] were retrieved. The Kaplan-Meier method was employed to calculate survival from the time of TIPS implantation and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model. Results were expressed as medians and ranges. Comparisons between groups were performed by using the Mann-Whitney Utest and the χ 2 test as appropriate. RESULTS:No difference could be seen in terms of age, sex, underlying disease or degree of portal pressure gradient (PPG) reduction between the ascites and the bleeding group. The PPG significantly decreased from 23.4 ± 5.3 mmHg (VB) vs 22.1 ± 5.5 mmHg (RA) before TIPS to 11.8 ± 4.0 vs 11.7 ± 4.2 after TIPS implantation (P = 0.001 within each group). There was a tendency towards more patients with stage CHILD A in the bleeding group compared to the ascites group (24 vs 6, P = 0.052). The median survival for the ascites group was 29 mo compared to > 60 mo for the bleeding group (P = 0.009). The number of radiological controls for stent patency was 6.3 for bleeders and 3.8 for ascites patients (P = 0.029). Kaplan-Meier calculation indicated that stent occlusion at first control (P = 0.027), ascites prior to TIPS implantation (P = 0.009), CHILD stage (P = 0.013), MELD score (P = 0.001) and those patients not having undergone liver transplantation (P = 0.024) were significant predictors of survival. In the Cox regression model, stent occlusion (P = 0.022), RA (P = 0.043), CHILD stage (P = 0.015) and MELD score (P = 0.004) turned out to be independent prognostic factors of survival. The anticoagulation management (P = 0.097), the porto-systemic pressure gradient (P= 0.460) and rebleeding episodes (P = 0.765) had no significant effect on the overall survival. CONCLUSION:RA, stent occlusion, initial CHILD stage and MELD score are independent predictors of survival in patients with TIPS, speaking for a close follow-up in these circumstances.

文摘AIM: To determine intestinal permeability,the serum tumor necrosis factor (TNF)-α level and urine nitric oxide (NO) metabolites are altered in liver cirrhosis (LC) with or without ascites. METHODS: Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol (PEG) 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-α concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay (ELISA) and Greiss reaction method,respectively. RESULTS: The intestinal permeability index wassignif icantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites (0.88 ± 0.12 vs 0.52 ± 0.05 or 0.53 ± 0.03,P < 0.05) and correlated with urine nitrite excretion (r = 0.98). Interestingly,the serum TNF-α concentra-tion was significantly higher in LC without ascites than in control subjects or in LC with ascites (198.9 ± 55.8 pg/mL vs 40.9 ± 12.3 pg/mL or 32.1 ± 13.3 pg/mL,P < 0.05). Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites (1170.9 ± 28.7 μmol/L vs 903.1 ± 55.1 μmol/L or 956.7 ± 47.7 μmol/L,P < 0.05). CONCLUSION: Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites,but the serum TNF-α concentration was not related to LC with ascites.
文摘Refractory ascites(RA)is a frequent and life-threatening complication of cirrhosis.In selected patients with RA,transjugular intrahepatic portosystemic shunt(TIPS)placement and liver transplantation(LT)are currently considered the best therapeutic alternatives to repeated large volume paracentesis.In patients with a contraindication to TIPS or LT,the alfapump®system(Sequana Medical,Ghent,Belgium)has been developed to reduce the need for iterative paracentesis,and consequently to improve the quality of life and nutritional status.We report here recent data on technical progress made since the first implantation,the efficacy and tolerance of the device,the position of the pump in the therapeutic arsenal for refractory ascites,and the grey areas that remain to be clarified regarding the optimal selection of patients who are potential candidates for this treatment.

文摘BACKGROUNDHepatic hydrothorax (HH) is an uncommon and difficult-to-manage complicationof cirrhosis with limited treatment options.AIMTo define the clinical outcomes of patients presenting with HH managed withcurrent standards-of-care and to identify factors associated with mortality.METHODSCirrhotic patients with HH presenting to 3 tertiary centres from 2010 to 2018 wereretrospectively identified. HH was defined as pleural effusion in the absence ofcardiopulmonary disease. The primary outcomes were overall and transplant-freesurvival at 12-mo after the index admission. Cox proportional hazards analysiswas used to determine factors associated with the primary outcomes.RESULTSOverall, 84 patients were included (mean age, 58 years) with a mean model forend-stage liver disease score of 29. Management with diuretics alone achievedlong-term resolution of HH in only 12% patients. At least one thoracocentesis wasperformed in 73.8% patients, transjugular intrahepatic portosystemic shuntinsertion in 11.9% patients and 33% patients received liver transplantation within12-mo of index admission. Overall patient survival and transplant-free survival at12 mo were 68% and 41% respectively. At multivariable analysis, current smoking [hazard ratio (HR) = 8.65, 95% confidence interval (CI): 3.43-21.9, P < 0.001) and acute kidneyinjury (AKI) (HR = 2.91, 95%CI: 1.21-6.97, P = 0.017) were associated with a significantly increasedrisk of mortality.CONCLUSIONCirrhotic patients with HH are a challenging population with a poor 12-mo survival despitecurrent treatments. Current smoking and episodes of AKI are potential modifiable factors affectingsurvival. HH is often refractory of diuretic therapy and transplant assessment should beconsidered in all cases.
