Heart failure and acute renal dysfunction in the cardiorenal syndrome

Just under 1 million people in the UK have symptomatic heart failure. Decompensated heart failure is associated with a particularly poor prognosis with in-hospital mortality at around 10%. Over the last 30 years renin-angiotensin-aldosterone system antagonists have been shown to have incremental benefit on improved quality of life, reduced hospitalisation and mortality rates in those with heart failure with reduced ejection fraction. Concomitant chronic kidney disease and 'acute kidney injury' are common and associated with adverse outcomes.In patients with decompensated heart failure, congestion is a key driver of deterioration in renal function. Decongestion is fundamental to successful management. Yet it is not uncommon to see prognostically important medication (such as angiotensin converting enzyme inhibitors and mineralocorticoid antagonists) inappropriately stopped, along with under-diuresis of the patient. This leaves the patient still in a state of congestion without the prognostic medication at discharge, with resultant adverse outcome. The British Society for Heart Failure and the Renal Association have produced consensus guidance to help guide management in a more consistent fashion based on heart failure classification, whether the patient is congested and the degree of renal impairment. Early heart failure specialist review is associated with improved patient outcomes.

Two Hearts at Risk: Emergency Alcohol Septal Ablation in a Pregnant Woman With Decompensated HOCM

Hypertrophic obstructive cardiomyopathy (HOCM) increases the risk for mother and fetus during pregnancy. Alcohol septal ablation (ASA) is an established procedure in nonpregnant patients with HOCM. In this report, we present a case of a 29-year-old woman in her 29th gestational week with decompensated HOCM undergoing a successful ASA. (Level of Difficulty: Advanced.).

Functional Status at Liver Transplant Waitlisting Correlates With Greater Odds of Encephalopathy, Ascites, and Spontaneous Bacterial Peritonitis

BACKGROUND & AIMS

Whether higher liver transplant (LT) waitlist mortality in patients with poor functional status (FS) is mediated by higher prevalence of cirrhosis complications is not clear. We aim to evaluate the impact of FS on risk of hepatic encephalopathy (HE), ascites, and spontaneous bacterial peritonitis (SBP) among adults listed for LT.

METHODS

Using 2005-2018 United Network for Organ Sharing LT data, we retrospectively evaluated the impact of FS on prevalence of ascites, HE, and SBP among adults listed for LT using Karnofsky Performance Status Score categories (KPSS-1: FS 80-100%, KPSS-2: 60-70%, KPSS-3: 40-50%, KPSS-4: 10-30%), stratified by underlying liver disease etiology. Between-group comparisons used chi-squared methods and adjusted multivariate logistic regression.

RESULTS

Among 100,618 adults listed for LT (68.8% male, 72.4% non-Hispanic white) 35.2% were KPSS-1, 36.6% KPSS-2, 15.7% KPSS-3, and 12.6% KPSS-4 at time of LT waitlist registration. Patients with worse FS were significantly more likely to have ascites, HE, and SBP at time of waitlist registration (KPSS-1 vs. KPSS-4: ascites, 66% vs. 93%; HE, 81% vs. 49%; SBP, 4% vs. 16%, p < 0.001 for all). On multivariate regression, compared with patients with KPSS-1, those with KPSS-4 had significantly higher odds of ascites (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.37-1.62, p < 0.01), HE (OR: 1.69, 95% CI: 1.59-1.80, p < 0.01), and SBP (OR: 2.17, 95% CI: 1.98-2.38, p < 0.01), which was observed across all liver disease etiologies.

CONCLUSION

Worse FS is associated with higher odds of cirrhosis complications including ascites, HE, and SBP, which was observed across all liver disease etiologies.

The impact of HBV flare on the outcome of HBV-related decompensated cirrhosis patients with bacterial infection

BACKGROUND

Hepatitis B virus (HBV) flare can occur in HBV patients either naïve or have interruption to treatment. Bacterial infection (BI) is a common complication of cirrhosis with potential severe outcomes. We aimed to assess the impact of HBV flare on the outcome of patients with HBV-related decompensated cirrhosis and BI.

METHODS

This was a retrospective study from 2 tertiary academic hospitals in Shanghai, China of HBV patients admitted with or developed BI during admission. The characteristics of BI, prevalence of HBV flare, its impact on organ failure, acute-on-chronic liver failure (ACLF) and 90-day survival were evaluated.

RESULTS

A total of 360 hospitalized patients (median age: 50 years, male: 79%, BI: at admission: 58.6%; during admission: 41.4%) were included. All patients including those with HBV flare (21%) received antiviral therapy after admission. Patients with HBV flare and BI had significantly higher percentage of liver (93.3% vs 48.8%), coagulation (64.0% vs 39.6%), cerebral (40.0% vs 21.8%) (all P < 0.01), and kidney failure (38.7% vs 26.3%, P < 0.05) compared to BI alone, associated with a higher risk of developing ACLF with a subdistribution hazard ratio (sHR) of 2.23 (95% confidence interval [CI]: 1.68-2.96). Multivariate analysis showed that ACLF development was the strongest risk factor for 90-day mortality (sHR, 95%CI: 7.36, 4.12-13.16).

CONCLUSIONS

In HBV-related decompensated cirrhosis patients admitted with BI, HBV flare increased the risk of additional organ failures and ACLF, raising the risk of 90-day mortality by seven-fold. Optimization of HBV treatment in these patients should minimize the risk of HBV flare with improved outcomes.

Advanced heart failure: A review

Heart failure (HF) has been recognized as a pandemic and is a serious clinical and health problem associated with significant mortality, morbidity and expenditure on healthcare, especially among older people. Progress in medicine has made it possible for an increasing number of people with HF to live longer than ever before. Therefore, a new and serious clinical problem has appeared - advanced heart failure (AHF). A better understanding of this issue is very important, because there are many more patients waiting for transplantations than there are available hearts. The role of the medical team is to keep the patient in the best condition until the heart transplant/implantation of left ventricular assist devices or at least to ensure the best possible quality of life. This article reviews the available data on AHF. The authors have succinctly presented different definitions and methods of the AHF diagnosis established by medical societies, as well as epidemiological data, methods of assessment, and possible treatment strategies.

Risk and outcome of hepatocellular carcinoma in liver cirrhosis in Southern Sweden: a population-based study

Background and aims: Liver cirrhosis is a risk factor for hepatocellular carcinoma (HCC). While the HCC risk is thought to be highest in hepatitis B and hepatitis C, the risk in other cirrhosis etiologies is not fully established. Therefore, we aimed to study the risk and outcome of HCC in alcoholic cirrhosis compared to cirrhosis of other etiologies, in Sweden. Material and methods: We used population-based medical registries to identify patients diagnosed with cirrhosis in the Scania region in southern Sweden between 2001 and 2010. Medical records were reviewed to identify all HCC cases and to register clinical parameters. All patients were followed until death, emigration or December 2017. Results: The cohort comprised 1317 patients with cirrhosis. A total of 200 patient developed HCC, including 75 with prevalent HCC. The annual incidence of HCC after six months was 1.5% in alcoholic cirrhosis and 4.7% in hepatitis C cirrhosis. In alcoholic cirrhosis, 40 patients were diagnosed with HCC during follow-up, of which 15 patients fulfilled the Milan criteria and 10 received treatment, curative or palliative. The overall median survival after HCC diagnosis was 7.7 months, with 4.5, 11 and 9.3 months, in cirrhosis due to alcohol, hepatitis C or remaining causes, respectively. Conclusion: We find an annual incidence of HCC in alcoholic cirrhosis of 1.5% indicating need for surveillance in these patients. Survival after HCC diagnosis was worst in alcoholic cirrhosis due to more advanced stage at diagnosis with few patients eligible for treatment.

Hepatic decompensation associated with an interferon-free antiviral therapy in patients with HCV-cirrhosis

Today, there is no complete clarity about the pathogenetic mechanisms of the hepatic decompensation in patients with HCV-cirrhosis during the course of direct-acting antiviral (DAAs) therapy. The current article describes several clinical observations of decompensation (with the development of liver failure and portal hypertension) in cirrhotic patients during the course of DAAs-therapy of hepatitis C. The authors present contemporary views and their own assumptions about the possible mechanisms of the hepatic decompensation associated with DAAs-therapy in patients with liver cirrhosis.

Ascites control by TIPS is more successful in patients with a lower paracentesis frequency and is associated with improved survival

Background & Aims

Refractory ascites is the main reason for the implantation of a transjugular intrahepatic portosystemic shunt (TIPS) in liver cirrhosis, but ascites control by TIPS fails in a relevant proportion of cases. Here, we investigated whether routine parameters pre-TIPS can predict persistent ascites after TIPS implantation and whether persistent ascites predicts long-term clinical outcome.

Methods

A detailed retrospective analysis of 128 patients receiving expanded polytetrafluoroethylene-covered stents for the treatment of refractory ascites was performed. Persistent ascites post-TIPS was defined as the prolonged need for paracentesis >3 months after TIPS. The influence of demographics, laboratory results, pre-TIPS heart and liver ultrasound results, and invasive hemodynamic parameters on persistent ascites was evaluated by univariable and multivariable logistic regression. Predictors of the composite endpoint liver transplantation/death were analyzed using a multivariable Cox regression.

Results

Ascites control post-TIPS was achieved in 95/128 patients (74%), whereas ascites remained persistent in 33/128 cases (26%). On multivariable analysis, a lower paracentesis frequency pre-TIPS (odds ratio 1.672; 95% CI 1.253–2.355) and lower baseline creatinine levels (odds ratio 2.640; CI 1.201–6.607) were associated with ascites control. Patients with persistent ascites post-TIPS had and impaired transplant-free survival (median 10.0 vs. 25.8 months), for which persistent ascites was the only independent predictor (hazard ratio 5.654; CI 3.019–10.59).

Conclusion

TIPS-placement in patients with lower paracentesis frequency and creatinine levels is associated with superior ascites control. Thus, TIPS implantation should be considered in moderate decompensation and not as a last resort. Persistent ascites post-TIPS seems to be the only predictor of liver transplantation and death.

Lay summary

The insertion of a transjugular intrahepatic portosystemic shunt (TIPS) in patients with refractory ascites should be considered in patients with moderate decompensation and not as a last resort, as lower paracentesis frequency and creatinine levels pre-TIPS are associated with superior ascites control. In turn, failure to control ascites seems to be the only predictor of liver transplantation and death.

•

Ascites control post-TIPS is superior if the TIPS is placed at lower paracentesis frequency and creatinine levels.

•

Transplant-free survival is decreased in patients with a failed ascites control post-TIPS.

•

TIPS-placement should be considered “early” in ascitic decompensation.

•

Close monitoring and prioritized organ allocation should be considered in patients with failed ascites control post-TIPS.

Collagen proportionate area is an independent predictor of long-term outcome in patients with non-alcoholic fatty liver disease

BACKGROUND

Collagen proportionate area (CPA) measurement is a technique that quantifies fibrous tissue in liver biopsies by measuring the amount of collagen deposition as a proportion of the total biopsy area. CPA predicts clinical outcomes in patients with HCV and can sub-classify cirrhosis.

AIM

To test the ability of CPA to quantify fibrosis and predict clinical outcomes in patients with NAFLD.

METHODS

We assessed consecutive patients with biopsy-proven NAFLD from three European centres. Clinical and laboratory data were collected at baseline and at the time of the last clinical follow-up or death. CPA was performed at two different objective magnifications, whole biopsy macro and ×4 objective magnification, named standard (SM) and high (HM) magnification respectively. The correlation between CPA and liver stiffness was assessed in a sub-group of patients.

RESULTS

Of 437 patients, 32 (7.3%) decompensated and/or died from liver-related causes during a median follow-up of 103 months. CPA correlated with liver stiffness and liver fibrosis stage across the whole spectrum of fibrosis. HM CPA was significantly higher than SM CPA in stages F0-F3 but similar in cirrhosis, reflecting a higher ability to capture pericellular/perisinusoidal fibrosis at early stages. Age at baseline (HR: 1.04, 95% CI: 1.01-1.08), HM CPA (HR: 1.04 per 1% increase, 95% CI: 1.01-1.08) and presence of advanced fibrosis (HR: 15.4, 95% CI: 5.02-47.84) were independent predictors of liver-related clinical outcomes at standard and competing risk multivariate Cox-regression analysis.

CONCLUSIONS

CPA accurately measures fibrosis and is an independent predictor of clinical outcomes in NAFLD; hence it merits further evaluation as a surrogate endpoint in clinical trials.

Temporal Trends in the Prevalence of Diabetes Decompensation (Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic State) Among Adult Patients Hospitalized with Diabetes Mellitus: A Nationwide Analysis Stratified by Age, Gender, and Race

Background

Disproportionate change in the burden of diabetes mellitus across various subgroups has been reported in the United States. However, changing landscape of the prevalence and mortality of decompensated diabetes (diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS)) remains indistinct across various age, gender, and racial groups of hospitalized diabetics.

Methods

The National Inpatient Sample (NIS) datasets (2007-2014) were sought to assess the prevalence and temporal trends in decompensated diabetes stratified by age, gender, and race and related in-hospital outcomes among the adult patients hospitalized with diabetes using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Discharge weights were used to obtain national estimates.

Results

Of 56.7 million hospitalizations with diabetes, 0.5 (0.9%) million patients revealed decompensated diabetes from 2007 to 2014. The decompensated diabetics consisted of younger (~52 vs. 66 yrs), more often black (24.2% vs. 17.3%) and Hispanic (12.9% vs. 10.9%) patients as compared to those without decompensation (p<0.001). Younger diabetes patients demonstrated the highest prevalence of in-hospital decompensation (18-44 yrs; 3.7%) with a relative increase of 32.4% (from 3.4% to 4.5%) from 2007 to 2014 (p_trend<0.001). Older diabetics (≥65 years) with decompensation suffered the highest in-hospital mortality (12.8%). The overall rate of decompensation was similar (0.9%) among male and female diabetes patients. However, over a period of 8 years, the rates of decompensation rose to 1.1% (p_trend<0.001) in males and 1.2% (p_trend<0.001) in females, respectively. All-cause in-hospital mortality among females with decompensated diabetes declined from 6.6% in 2007 to 5.9% in 2014 (p_trend=0.019). However, there was no significant drop in in-hospital mortality among male diabetics with acute decompensation (6.7% in 2007 to 6.8% in 2014, p_trend=0.811). We observed significantly increasing trends in decompensated diabetes among all race groups between 2007 and 2014 (p_trend<0.001). The in-hospital mortality was highest among Asian or Pacific Islander (0.9%) diabetes patients with decompensation from 2007 to 2014. There was a declining trend in the inpatient mortality among Asian or Pacific Islander (p_trend=0.029) and Hispanic (p_trend<0.001) patients with decompensated diabetes, whereas other race groups did not observe any significant decline in mortality over the study period. Diabetes hospitalizations with decompensation demonstrated significantly higher in-hospital mortality (6.3% vs. 2.6%; p<0.001), average length of stay (7.7 vs. 5.4 days; p<0.001), hospital charges ($65,904 vs. $42,889, p<0.001), and more frequent transfers to short-term hospitals (3.9% vs. 2.9%; p<0.001) in comparison to those without decompensation. The rates of acute myocardial infarction (AMI) (10.4% vs. 4.8%; p<0.001), stroke (4.0% vs. 3.3%; p<0.001) and venous thromboembolism (3.5% vs. 2.6%; p<0.001) were substantially higher among diabetics with decompensation compared to those without.

Conclusions

There was an increasing trend in the prevalence of decompensated diabetes from 2007 to 2014, most remarkable among younger black male diabetics. The patients with decompensated diabetes suffered higher in-hospital mortality and rates of AMI, stroke and venous thromboembolism, there was no significant decline in the mortality between 2007 and 2014.

Long-term Prognosis of Acute-on-Chronic Liver Failure Survivors

GOALS

We aimed to investigate significant factors influencing the long-term prognosis of patients who survived acute-on-chronic liver failure (ACLF).

BACKGROUND

The mortality of ACLF is predominantly affected by the organ failure severity. However, long-term outcomes of patients who survive ACLF are not known.

STUDY

A cohort of 1084 cirrhotic patients who survived for more than 3 months following acute deterioration of liver function was prospectively followed. ACLF was defined by the European Association for the Study of the Liver Chronic Liver Failure Consortium definition.

RESULTS

The mean follow-up duration was 19.4±9.9 months. In the subgroup of patients without previous acute decompensation (AD), ACLF occurrence did not affect long-term outcomes. However, in patients with previous AD, ACLF negatively affected long-term transplant-free survival even after overcoming ACLF (hazard ratio, 2.00, P=0.012). Previous AD was the significant predictive factor of long-term mortality and was independent of the Model for End-stage Liver Disease score in these ACLF-surviving patients. Organ failure severity did not affect transplant-free survival in patients who survived an ACLF episode.

CONCLUSIONS

A prior history of AD is the most important factor affecting long-term outcomes following an ACLF episode regardless of Model for End-stage Liver Disease score. Prevention of a first AD episode may improve the long-term transplant-free survival of liver cirrhosis patients.

How I treat… alcohol-related liver disease

Age-standardised mortality from liver disease in the United Kingdom has risen by 400% since 1970, with three-quarters of deaths from alcohol-related liver disease (ARLD). The 2013 National Confidential Enquiry into Patient Outcome and Death report found that only 47% of the patients dying in hospital from liver disease experienced 'good' care. We discuss common complications in the care of patients with ARLD and the evidence-based best practice that can improve patient outcomes, with a focus on the initial management of patients presenting acutely to the medical take.

The Value of Liver Transplantation for Methylmalonic Acidemia

Introduction: MMA is a rare autosomal recessive disorder with the manifestation of recurrent and severe episodes of acute metabolic decompensation or a variety of long-term complications that require timely treatment. While conventional long-term medical and dietary management cannot prevent rapid progression of conditions in patients with severe complications, LT, or CKLT has become an option. Methods: We reviewed the literature for MMA patients undergoing LT/CKLT published since 2006, and data on metabolic decompensation status, protein dietary, neurological damage, renal insufficiency, and developmental delay before and after transplantations were compared to evaluate the clinical value of the procedure in the treatment of MMA. Results: To date, some successful LTs/CKLT procedures have prolonged survival and resulted in better quality of life in patients (lowered urine/plasma MMA levels but still much higher than normal, reduced onset of metabolic stroke, occasional improved developmental delay, and relaxed protein diet), although these procedures cannot reverse neurological damage or thoroughly stop the progress of complications, such as renal dysfunction. Conclusion: LT is the only effective treatment for MMA patients with recurrent metabolic decompensation. However, it is still possible that neurological and renal damage remains irreversible. Metabolism-correcting medications should be administered even after surgery.

Complicated Complication: How Interventional Radiologists Should Manage Acute Iatrogenic Cardiac Tamponade

Computed tomography guided biopsies are common interventional procedures that are necessary for confirmation of imaging findings. Additionally, percutaneous biopsies are necessary for the elucidation of a patient’s clinical findings with disease pathology. Though interventionists perform these procedures regularly without consequence, various complications may arise depending on the tissues biopsied. Examples of such complications may include hemorrhage, hematoma formation, or perforation of surrounding vessels. In the case of mediastinal biopsies, less common but higher-risk complications may include pneumothorax, perforation of arterial vessels, and damage to the cardiac tissues resulting in decompensation. Interventionists should understand the risks of performing these procedures and should be prepared to intervene if life-threatening complications arise. As interventional cardiologists are often prepared to manage decompensating cardiac complications, interventional radiologists must likewise anticipate the same to occur when conducting procedures that may affect cardiac tissues. The following case demonstrates a technique for correcting a complicated complication arising from a mediastinal biopsy, which resulted in a pericardial effusion and patient decompensation.

[Hepatic decompensation associated with an interferon-free antiviral therapy in patients with HCV-cirrhosis]

Today, there is no complete clarity about the pathogenetic mechanisms of the hepatic decompensation in patients with HCV-cirrhosis during the course of direct-acting antiviral (DAAs) therapy. The current article describes several clinical observations of decompensation (with the development of liver failure and portal hypertension) in cirrhotic patients during the course of DAAs-therapy of hepatitis C. The authors present contemporary views and their own assumptions about the possible mechanisms of the hepatic decompensation associated with DAAs-therapy in patients with liver cirrhosis.

Care of Patients Following Cure of Hepatitis C Virus Infection

The vast majority of persons with chronic hepatitis C virus (HCV) infection will achieve virologic cure with the current direct-acting antiviral therapies. Prevention of reinfection is an important aspect of postcure management and key to the elimination of HCV infection globally. Equally important aspects of postcure care are the prevention of liver disease progression and the management of complications in patients who have significant fibrosis at the time of achieving cure. Patients with advanced fibrosis need to remain under surveillance for liver complications, including hepatocellular carcinoma. All patients are potentially at risk for liver disease progression if other factors causing liver injury are present, such as harmful levels of alcohol use or risk factors for fatty liver including obesity, diabetes, and other metabolic comorbidities. Fatty liver is a particular threat to the long-term well-being of patients after HCV cure due to the high prevalence of its risk factors in this population. Strong counseling messages and ongoing monitoring are key.

Outcome of endoscopic retrograde cholangiopancreatography in patients with clinically defined decompensated liver cirrhosis

OBJECTIVE

Decompensated liver cirrhosis (LC) can negatively affect the outcome of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to compare the efficacy and safety of ERCP in patients with clinically defined compensated and decompensated LC.

METHODS

In a single tertiary hospital, 146 endoscopic sphincterotomy-naive patients with LC who underwent ERCP between 2005 and 2016 were reviewed. Patients with LC who had experienced variceal bleeding, ascites or hepatic encephalopathy were included in the decompensated LC group. Cannulation, technical and clinical successes, and major post-ERCP adverse events including bleeding, pancreatitis, cholangitis and perforation were compared between the two groups.

RESULTS

Patients were divided into compensated and decompensated LC groups. Their baseline characteristics were not different, except for comorbid malignancy (22.3 % vs 38.5%, P = 0.038) and preprocedural transfusion (7.4% vs 36.5%, P < 0.001). The cannulation (97,9% vs 94.2%, P = 0.348) and technical (95.7% vs 88.5%, P = 0.167) success rates were not different. The clinical success rate was lower in the decompensated LC group (95.7% and 78.8%, P = 0.003), mainly due to comorbid hepatobiliary malignancy. Post-ERCP pancreatitis (6.4% vs 30.8%, P = 0.008) and cholangitis (18.1% vs 32.7%, P = 0.046) rates were higher in the decompensated LC group.

CONCLUSIONS

Despite lower clinical success rates due to comorbid hepatobiliary malignancy, ERCP in patients with decompensated LC is technically feasible. Because postprocedural cholangitis and pancreatitis are more frequent in patients with decompensated LC, greater procedural precautions are needed in these patients.

Rifaximin has the potential to prevent complications of cirrhosis

BACKGROUND

Cirrhosis-related complications are associated with poor prognosis. With our analyses, we examined the potential benefit of rifaximin in reducing the risk of developing cirrhosis-related complications.

METHODS

Adults with cirrhosis and hepatic encephalopathy (HE) in remission were randomly assigned to receive rifaximin 550 mg twice daily or placebo for 6 months with concomitant lactulose permitted. Post hoc analyses examined time to cirrhosis-related complications (HE, spontaneous bacterial peritonitis (SBP), variceal bleeding, acute kidney injury/hepatorenal syndrome). Subgroup analyses evaluated efficacy for select baseline disease characteristics.

RESULTS

Of patients receiving rifaximin (n = 140) and placebo (n = 159), 53.6% and 49.1%, respectively, had baseline Model for End-Stage Liver Disease (MELD) score ⩾ 12 and international normalized ratio (INR) ⩾ 1.2. Baseline ascites was observed in 36.4% (rifaximin) and 34.6% (placebo) of patients. In patients with MELD score ⩾ 12 and INR ⩾ 1.2, rifaximin reduced the relative risk (RR) of any first complication experienced during trial by 59% [hazard ratio (HR) = 0.41, 95% confidence interval (CI): 0.25-0.67; p < 0.001] versus placebo. For patients with baseline ascites, rifaximin reduced the RR of any first complication experienced during trial by 42% versus placebo (HR = 0.58, 95% CI: 0.34-1.0; p = 0.045). For some subgroups, there was a decrease in RR of complications of SBP, variceal bleeding, and acute kidney injury/hepatorenal syndrome with rifaximin versus placebo, although there were few events reported in the study.

CONCLUSION

Rifaximin may reduce the incidence of cirrhosis-related complications and the recurrence of overt HE.[ClinicalTrials.gov identifier: NCT00298038.].

Impact of previous hepatitis B infection on the clinical outcomes from chronic hepatitis C? A population-level analysis

Chronic coinfection with hepatitis C virus (HCV) and hepatitis B virus (HBV) is associated with adverse liver outcomes. The clinical impact of previous HBV infection on liver disease in HCV infection is unknown. We aimed at determining any association of previous HBV infection with liver outcomes using antibodies to the hepatitis B core antigen (HBcAb) positivity as a marker of exposure. The Scottish Hepatitis C Clinical Database containing data for all patients attending HCV clinics in participating health boards was linked to the HBV diagnostic registry and mortality data from Information Services Division, Scotland. Survival analyses with competing risks were constructed for time from the first appointment to decompensated cirrhosis, hepatocellular carcinoma (HCC) and liver-related mortality. Records of 8513 chronic HCV patients were included in the analyses (87 HBcAb positive and HBV surface antigen [HBsAg] positive, 1577 HBcAb positive and HBsAg negative, and 6849 HBcAb negative). Multivariate cause-specific proportional hazards models showed previous HBV infection (HBcAb positive and HBsAg negative) significantly increased the risks of decompensated cirrhosis (hazard ratio [HR]: 1.29, 95% CI: 1.01-1.65) and HCC (HR: 1.64, 95% CI: 1.09-2.49), but not liver-related death (HR: 1.02, 95% CI: 0.80-1.30). This is the largest study to date showing an association between previous HBV infection and certain adverse liver outcomes in HCV infection. Our analyses add significantly to evidence which suggests that HBV infection adversely affects liver health despite apparent clearance. This has important implications for HBV vaccination policy and indications for prioritization of HCV therapy.

Preliminary experience with a novel Multisensor algorithm for heart failure monitoring: The HeartLogic index

We report the first case of a patient in whom an implantable cardioverter-defibrillator (ICD) endowed with HeartLogic, a novel algorithm for heart failure (HF) monitoring, was implanted in clinical practice. The good temporal association between HeartLogic index threshold crossings and HF hospitalizations confirms the high sensitivity in detecting gradual worsening of HF.

Serum Wisteria floribunda agglutinin-positive Mac-2-binding protein evaluates liver function and predicts prognosis in liver cirrhosis

OBJECTIVE

Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA⁺ -M2BP) is a novel glycobiomarker for evaluating liver fibrosis, but less is known about its role in liver cirrhosis (LC). This study aimed to investigate the utility of WFA⁺ -M2BP in evaluating liver function and predicting prognosis of cirrhotic patients.

METHODS

We retrospectively included 197 patients with LC between 2013 and 2016. Serum WFA⁺ -M2BP and various biochemical parameters were measured in all patients. With a median follow-up of 23 months, liver-related complications and deaths of 160 patients were recorded. The accuracy of WFA⁺ -M2BP in evaluating liver function, predicting decompensation and mortality were measured by the receiver operating characteristic (ROC) curve, logistic and Cox's regression analyses, respectively.

RESULTS

WFA⁺ -M2BP levels increased with elevated Child-Pugh classification, especially in patients with hepatitis B virus (HBV) infection. ROC analysis confirmed the high reliability of WFA⁺ -M2BP for the assessment of liver function using Child-Pugh classification. WFA⁺ -M2BP was also significantly positively correlated with the model for end-stage liver disease (MELD) score. Multivariate logistic regression analysis indicated WFA⁺ -M2BP as an independent predictor of clinical decompensation for compensated patients (odds ratio 11.958, 95% confidence interval [CI] 1.876-76.226, P = 0.009), and multivariate Cox's regression analysis verified WFA⁺ -M2BP as an independent risk factor for liver-related death in patients with HBV infection (hazards ratio 10.596, 95% CI 1.356-82.820, P = 0.024).

CONCLUSION

Serum WFA⁺ -M2BP is a reliable predictor of liver function and prognosis in LC and could be incorporated into clinical surveillance strategies for LC patients, especially those with HBV infection.

Bacterial infection-triggered acute-on-chronic liver failure is associated with increased mortality

BACKGROUND & AIMS

Acute-on-chronic liver failure (ACLF) is characterized by an acute deterioration of liver function in patients with cirrhosis in combination with recently defined organ failures. Our aim was to independently validate the prognostic value of the recently established EASL-CLIF-Consortium definition of ACLF and to identify new predictors of short-term mortality.

METHODS

Patients with cirrhosis and the International Classification of Diseases, Tenth Revision diagnosis of (sub)acute liver failure were retrospectively categorized according to the EASL-CLIF-Consortium definition. Logistic regression analyses were performed to identify clinical and epidemiological predictors of 30- and 90-day mortality.

RESULTS

From 2008 to 2015, 257 patients were included. Overall, 173 (67%) patients met the EASL criteria for ACLF (grade 1: n = 43 [25%], grade 2: n = 52 [30%], grade 3: n = 79 [45%]). Mortality within 30 days in patients without ACLF was 3.6%, and 18.6%, 37.3% and 62.0% in patients with ACLF grades 1, 2 and 3 respectively. Outcome of patients with bacterial infection-triggered ACLF was distinct from non-infection-triggered ACLF (71.6% vs 33.8% 30-day survival, P < .001), and infection-triggered ACLF was independently associated with increased mortality (odds ratio [OR] = 4.28, P < .001). Pneumonia was a particularly frequent infection and burdened with high mortality. In addition, infections with multidrug-resistant organisms were frequent and independently associated with mortality (P = .030, OR = 4.41), as was glycopeptide antibiotic therapy as initial empirical antibiotic therapy (P = .005).

CONCLUSIONS

This study confirmed the EASL-CLIF-Consortium definition of ACLF as strong predictor of mortality in patients with acute decompensation of cirrhosis. However, we have observed a remarkably higher mortality in infection-triggered ACLF compared to other precipitating events.

[Observation on effect of retraining therapy in patients with chronic tinnitus]

Objective:To analyze the curative effect of tinnitus retraining therapy on patients with chronic decompensated tinnitus and to explore an effective method to treat patients with chronic decompensated tinnitus.Method:Thirty patients were treated for tinnitus retraining therapy for 12 months. The content of retraining therapy includes: tinnitus counseling,low intensity natural sound therapy, shift attention, and relaxation training.Result:The severity of tinnitus was compared in grading before treatment and after 12 months treatment: 56.7%(17/30) of grade Ⅲ before treatment, 36.7%(11/30) of grade Ⅳ and 6.7% (2/30) of grade Ⅴ;16.7%(5/30) of grade Ⅰ after treatment, 60.0% (18/30) of grade Ⅱ,16.7%(5/30) of grade Ⅲ,6.7% (2/30) of grade Ⅳ, where compensatory tinnitu was 76.7%(23/30), and decompensated tinnitus was 23.3%(7/30). The composition ratio of 30 subjects compensated tinnitus and decompensated tinnitus before and after treatment has significant changes, with statistical differences(P<0.01). The mean score of tinnitus severity before treatment was 14.40±2.60 in 30 subjects and 9.00±2.82 after treatment in assessment scale. There was a significant difference between the both groups(P<0.01).Conclusion:Tinnitus retraining therapy is an effective treatment of chronic decompensated tinnitus.
