A randomized multicenter trial of a chronic disease management intervention for decompensated cirrhosis. The Australian Liver Failure (ALFIE) trial.

BACKGROUND AND AIMS: Improving the care of decompensated cirrhosis is a significant clinical challenge. The primary aim of this trial was to assess the efficacy of a chronic disease management (CDM) model to reduce liver-related emergency admissions (LREA). The secondary aims were to assess model effects on quality-of-care and patient-reported outcomes. APPROACH AND RESULTS: The study design was a 2-year, multicenter, randomized controlled study with 1:1 allocation of a CDM model versus usual care. The study setting involved both tertiary and community care. Participants were randomly allocated following a decompensated cirrhosis admission. The intervention was a multifaceted CDM model coordinated by a liver nurse. A total of 147 participants (intervention=75, control=71) were recruited with a median Model for End-Stage Liver Disease score of 19. For the primary outcome, there was no difference in the overall LREA rate for the intervention group versus the control group (incident rate ratio 0.89; 95% CI: 0.53-1.50, p=0.666) or in actuarial survival (HR=1.14; 95% CI: 0.66-1.96, p=0.646). However, there was a reduced risk of LREA due to encephalopathy in the intervention versus control group (HR=1.87; 95% CI: 1.18-2.96, p=0.007). Significant improvement in quality-of-care measures was seen for the performance of bone density (p<0.001), vitamin D testing (p<0.001), and HCC surveillance adherence (p=0.050). For assessable participants (44/74 intervention, 32/71 controls) significant improvements in patient-reported outcomes at 3 months were seen in self-management ability and quality of life as assessed by visual analog scale (p=0.044). CONCLUSIONS: This CDM intervention did not reduce overall LREA events and may not be effective in decompensated cirrhosis for this end point.

Acute on chronic liver failure: A South Australian experience.

Background and Aim: Acute on chronic liver failure (ACLF) is a clinical syndrome described in patients with acute decompensation (AD) of cirrhosis, characterized by organ failures and high mortality. Intensive management, including liver transplantation (LT), has been shown to improve survival. To address the limited Australian data on ACLF, we describe the prevalence, clinical profile, and outcome of ACLF in an Australian cohort of hospitalized patients. Methods: A retrospective review of hepatology admissions in a tertiary hospital from 1 January 2017 to 31 December 2019 identified AD and ACLF cohorts, as defined by the European Association for Study of the Liver definition. Patient characteristics, clinical course, survival at 28- and 90-day survival, and feasibility of LT were analyzed. Results: Among the 192 admissions with AD, 74 admissions (39%) met ACLF criteria. A prior diagnosis of alcohol-related cirrhosis was highly prevalent in both cohorts. Grade-1 ACLF was the most frequent (60%), with renal failure being the commonest organ failure; 28-day (23% vs 2%, P = <0.001) and 90-day mortality (36% vs 16%, P = 0.002) were higher in ACLF than AD. Due to ongoing alcohol use disorder (AUD), only six patients underwent LT assessment during ACLF admission. Conclusion: ACLF was common in our cohort of cirrhosis with AD and was associated with high mortality. AUD despite prior cirrhosis diagnosis was a barrier to LT. Prioritization of ACLF patients for LT after addressing AUD and relaxation of the 6-month abstinence rule may improve ACLF survival and should be addressed in prospective studies.

Integrating smart phone applications in the management of cirrhotic patients: A scoping review.

Background and Aim: Chronic liver disease and cirrhosis is a significant cause of healthcare utilization and patient morbidity and mortality worldwide. Smartphone applications have high uptake in most communities and therefore have great potential to provide remote support solutions to this patient population. The aim of this scoping review was therefore to provide a comprehensive overview using narrative synthesis on the use of smartphone-application-based digital interventions in cirrhotic populations. Materials and Methods: PRISMA guidelines were followed, with two independent researchers identifying 10 relevant studies. Patients studied were predominantly those with decompensated cirrhosis, and hepatic encephalopathy was the most common complication studied. Results: Smartphones were the most common platform used, but training periods, prior to commencement of the study, were rarely offered. Patient engagement rates with the technology were reported only in three studies, but all reported high (>50%) rates of engagement. Only one study examined the clinical effects of their digital intervention, with a 38% reduction in readmission rate reported. Conclusion: Overall, the use of smartphone apps in cirrhosis is in an early phase of development and evaluation but preliminary studies suggest significant potential as an adjunct to routine medical care. Further high-quality studies of well-designed digital interventions are needed to advance this promising early experience.

Prevalence of Risk Factors for Nonalcoholic Fatty Liver Disease in Middle-Aged and Elderly Patients With Cryptogenic Cirrhosis.

Aim of the study: To study the prevalence of risk factors for nonalcoholic fatty liver disease (NAFLD) in middle-aged (40-59 years) and elderly patients (≥60 years) with cryptogenic cirrhosis as compared to those with hepatitis B or C virus (HBV or HCV) related cirrhosis. Methods and materials: Between August 2013 and December 2014, cases (cryptogenic cirrhosis) and controls (HBV/HCV cirrhosis) above 40 years of age were prospectively recruited and assessed for the cause and prevalence of risk factors for NAFLD. Results: One hundred eighteen cases (male-74%; age 55 (40-74) years; median (range); Child's class A:B:C-46:38:16) and 59 controls (male-80%; age 55.5 (40-69) years; Child's class A:B:C-56:30:14) were enrolled. Obesity (53% v/s 39%, P-0.081), diabetes mellitus (DM) (52% v/s 27%; P-0.002), family history of DM (30% v/s 13%; P-0.016), family history of Obesity (21% v/s 3.5%; P-0.002) and metabolic syndrome (65% v/s 44%; P-0.01) were more among cases than controls. Lifetime weight as obese was also longer in cases than in controls (5.9 ± 6.2 years v/s 3.2 ± 5.1 years, P-0.002). On subgroup analysis, in elderly age group, DM (55% v/s 17%, P-0.006), family history of DM (40% v/s 11%, P-0.025), metabolic syndrome (76% v/s 44%, P-0.017) and family history of obesity (19% v/s 0, P-0.047) were more common in cases as compared to controls, where as in the middle-age group, family history of obesity was the only significant factor (22% v/s 5%, P-0.025). Lifetime weight as obese was longer in cases than controls in both middle and elderly age groups. Conclusion: Among middle-aged and elderly patients with cirrhosis, there was a higher prevalence of risk factors for NAFLD in those with cryptogenic cirrhosis, compared to those with HBV or HCV cirrhosis.

Impact of cardiac dysfunction on morbidity and mortality in liver transplant candidates.

The prognostic role of cardiac dysfunction in cirrhotic patients is increasingly recognized. We studied its impact on morbidity and mortality before and after liver transplantation (LT) including development of post-transplant cardiovascular disease (CVD). In this retrospective study, cirrhotic patients who underwent LT assessment from January 2010 to December 2020 were reviewed. Demographics, cardiac investigations and clinical courses were analyzed to identify the prevalence of cardiac dysfunction and its role in LT outcomes. Survival analysis was performed using Cox proportional hazard regression modelling, with LT as a time-varying covariate and as an interaction variable with cardiac dysfunction. Three hundred and eight patients (70% male) were studied. The median (interquartile range) age at LT assessment was 56 (12) years. Cardiac dysfunction was found in 178 (58%) patients (diastolic, 169; systolic, 26; both, 17) and was significantly associated with hepatorenal syndrome/acute kidney injury and peri- and post-transplant morbidity (adjusted odds ratio [aOR] 1.94, 95% CI 1.06-3.52, P < .001; aOR 2.01, 95% CI 1.06-3.82, P = .033; aOR 1.9, 95% CI 1.01-3.65, P = .023, respectively). Cardiac dysfunction was not associated with mortality before (adjusted hazard ratio [aHR] 1.01, 95% CI .99-1.01) or after LT (aHR .74, 95% CI .4-1.05. Post-transplant CVD (61% cardiac failure) occurred in 36 patients, and there was no significant association with cardiac dysfunction (P = .11). Cardiac dysfunction was common in LT candidates and was significantly associated with morbidity before and after LT. Studies on the role of advanced echocardiographic parameters to improve diagnosis of cardiac dysfunction and optimize LT outcomes are needed.

Association of physiological reserve measures with adverse outcomes following liver transplantation.

BACKGROUND AND AIM: The comparative utility of physiological reserve measures in predicting important clinical outcomes following liver transplantation (LT) requires further study. The aim of this work was therefore to compare the utility of physiological reserve measures in predicting early adverse clinical outcomes post-LT. METHODS: A single-center, retrospective cohort study of LT patients consecutively recruited between 1 January 2015, and 31 August 2020. Outcomes measured were sepsis and death within 12 months of LT, hospital length of stay (LOS), and intensive care LOS. Physiological reserve measures were handgrip strength, mid-arm muscle circumference, and cardiopulmonary exercise testing (CPET) measures. Analysis was performed using univariate and multivariate logistic regression for sepsis and death, and univariate and multivariate Cox regression for hospital and intensive care LOS. RESULTS: Data were obtained for 109 subjects. Patients were predominantly (64%) male with a median (interquartile range [IQR]) age of 57 (49-63) and median (IQR) Model for End-Stage Liver Disease score of 16 (11-21). In multivariate analysis, the odds of sepsis were lower in patients in the highest versus lowest tertile (odds ratio = 0.004; 95% confidence interval [CI] 0.00-0.13; P = 0.002). Hospital LOS was linearly associated with handgrip strength (hazard ratio [HR] = 1.03; 95% CI 1.00-1.06; P = 0.03) in multivariate analysis. Intensive care LOS was associated with peak VO2 (HR 1.83; 95% CI 1.06-3.16; P = 0.03) and VE/VCO2 slope (HR 0.71; 95% CI 0.58-0.88; P = 0.002) in multivariate analysis. CONCLUSION: Handgrip strength and CPET both identify candidates at high risk of adverse outcomes after LT.

Measuring quality of hepatitis B care in a remote Australian Aboriginal community: opportunities for improvement.

BACKGROUND: Chronic hepatitis B (CHB) infection remains a significant public health issue for Indigenous Australians, in particular for remote communities. AIM: To evaluate the spectrum of hepatitis B virus (HBV) care provided to a remote Aboriginal community. Measures studied included screening, seroprevalence, vaccination rates and efficacy, and HCC risk and surveillance adherence. METHODS: A retrospective audit of HBV care received by all permanent residents currently attending a remote Aboriginal Health service. This study was endorsed by both the local Aboriginal Health service and the Aboriginal Health Council of South Australia. RESULTS: A total of 208 patients attended the clinic, of whom 52% (109) were screened for HBV. Of these, 12% (13) had CHB and 20% (22) had evidence of past infection. Similarly, of the 208 attending patients, complete vaccination was documented in 48% (99). Of the 33 patients with post-vaccination serology, 24% (8) had subtherapeutic (<10 IU/mL) levels of HBsAb. Subtherapeutic HBsAb was independently associated with higher Charlson Comorbidity scores (odds ratio = 17.1; 95% confidence interval 1.2-243.3; P = 0.036). Definitive breakthrough infection was identified in 6% (2) patients. One HBsAg positive patient was identified as needing HCC surveillance, but had not undertaken HCC surveillance. CONCLUSION: Opportunities to improve the quality of CHB care through increased HBV vaccination, screening and adherence to HCC surveillance were identified. High rates of subtherapeutic vaccine responses and documented breakthrough infection raises concerns about the effectiveness of current CHB vaccines in this population.

Nurse Led Clinics; a Novel Model of Care for Compensated Liver Cirrhosis: A Qualitative Analysis.

A nurse-led cirrhosis clinic model for management of stable, compensated cirrhotic patients is practised in our unit since 2013, wherein these patients are reviewed every six months by specialist nurses in community clinics under remote supervision of hepatologists. We evaluated the experiences of patients and healthcare providers involved in the model to understand the acceptability, strengths, and limitations of the model and obtain suggestions to improve. A qualitative design using in-depth interviews was employed, followed by thematic analysis of eight patients, one attending physician both nurse and hospital clinics, four hepatologists, and three experienced specialist nurses running the nurse-led cirrhosis clinic. Patients expressed satisfaction and a good understanding of the nurse-led cirrhosis clinic, preferring it to hospital clinics for better accessibility and the unique nurse-patient relationship. Upskilling and provision of professional care in a holistic manner were appreciated by specialist nurses. The hepatologists expressed confidence and satisfaction, although they acknowledged the difference between the medical training of specialist nurses and hepatologists. The greater availability of hospital clinic time for sick patients was welcomed. Increased specialist nurse staffing, regular forums to promote specialist nurse learning, and formalization of the referral process were suggested. No adverse experiences were reported by patients or staff. The nurse-led cirrhosis clinic model for compensated liver cirrhosis was well received by patients, hepatologists, and specialist nurses. Wider implementation of the model could be considered after further investigations in other settings.

Outcomes of transjugular intrahepatic portosystemic shunt procedures: a 10-year experience.

INTRODUCTION: Transjugular intrahepatic portosystemic shunt (TIPSS) is an effective modality in reducing portal pressure, and its current main indications are for the management of recurrent ascites and variceal bleeding. The demand and indications for TIPSS are growing. However, it is a complicated and technically demanding procedure with poorer outcomes associated with low volume centres. The aim of this study was, therefore, to review the outcomes of TIPSS at a 'low volume' single centre. Outcomes assessed included indications, safety, efficacy and survival. METHODS: A retrospective study was undertaken of all patients who underwent a TIPSS procedure over 10 years at tertiary referral centre for complex liver disease and transplantation. Kaplan-Meier method was used to calculate actuarial survival and log-rank analysis was used to determine significant differences in survival. RESULTS: Thirty-eight patients underwent the TIPSS procedure between January 2008 and December 2018. Technical, haemodynamic and clinical success were 95%, 92% and 92% respectively. Cumulative survival at one month, one year and five years were 86.8%, 72% and 44.7% respectively. Results achieved standards published in practice parameters to evaluate TIPSS safety and efficacy. CONCLUSION: At a low volume centre, TIPSS usage was associated with high rates of technical, haemodynamic (HPVG reduction) and clinical success. Low volume should not be a contraindication to providing a TIPSS service; however, auditing outcomes and understanding specific institutional factors that influence quality are important requirements for low volume centres.

Psychometric validation of the Partners in Health scale as a self-management tool in patients with liver cirrhosis.

BACKGROUND AND AIM: Liver cirrhosis is a chronic disease complicated by recurrent hospital admissions. Self-management skills could facilitate optimal disease management. At present there is no validated instrument for measuring self-management in these patients. Hence, we evaluated the internal reliability and construct validity of the Partners in Health (PIH) scale, a chronic condition self-management tool in cirrhotic patients. METHODS: In this prospective cohort study, the PIH scale was administered to 133 consenting patients within a Chronic Liver Failure Program of a tertiary hospital from February 2017 to May 2018. A Bayesian confirmatory factor analysis was used to evaluate a priori four-factor structure. Omega coefficients and 95% credible intervals (CrI) were used to assess internal reliability. Known-group validity was assessed in patients receiving active case management (n = 60) versus those without (n = 73). RESULTS: The mean (± standard deviation (SD)) age of the participants was 62 (±11) years. Model fit for the hypothesised model was adequate (posterior predictive P-value = 0.073) and all hypothesised factor loadings were substantial (>0.6) and significant (P < 0.001). Omega coefficients (95% CrI) for the PIH subscales of Knowledge, Partnership, Management and Coping were 0.88 (0.82-0.91), 0.68 (0.57-0.76), 0.92 (0.89-0.94) and 0.89 (0.85-0.92) respectively. The mean (±SD) overall PIH score was higher in patients receiving case management compared to those without case management (81 ± 12 vs 73 ± 17, P < 0.001). CONCLUSION: The dimensionality, known-group validity and reliability of the PIH scale for measuring self-management in patients with liver cirrhosis were confirmed. Its clinical predictive value requires further assessment.

Outcomes of community-based hepatitis C treatment by general practitioners and nurses in Australia through remote specialist consultation.

BACKGROUND: A unique model of care was adopted in Australia following introduction of universal subsidised direct-acting antiviral (DAA) access in 2016 in order to encourage rapid scale-up of treatment. Community-based medical practitioners and integrated hepatitis nurses initiated DAA treatment with remote hepatitis specialist approval of the planned treatment without physical review. AIMS: To evaluate outcomes of community-based treatment of hepatitis C virus (HCV) through this remote consultation process in the first 12 months of this model of care. METHODS: A retrospective chart review of patients undergoing community-based HCV treatment from general practitioners and integrated hepatitis nurse consultants through the remote consultation model in three state jurisdictions in Australia from 1 March 2016 to 28 February 2017. RESULTS: Sustained virological response at 12 weeks (SVR12) was confirmed in 383 (65.1%) of 588 subjects intended for treatment with a median follow-up time of 12 months (interquartile range 9-14 months). The SVR12 test was not performed in 159 (27.0%) of 588 and 307 (52.2%) of 588 did not have liver biochemistry rechecked following treatment. Subjects who completed follow up exhibited high SVR12 rates (383/392; 97.7%). Nurse-led treatment was associated with higher confirmation of SVR12 (73.7% vs 62.4%; P = 0.01) and liver biochemistry testing post treatment (57.5% vs 45.0%; P = 0.01). CONCLUSIONS: Community-based management of HCV through remote specialist consultation may be an effective model of care. Failure to check SVR12, recheck liver biochemistry and appropriate surveillance in patients with cirrhosis may emerge as significant issues requiring further support, education and refinement of the model to maximise effectiveness of future elimination efforts.

Cost effectiveness of treatment models of care for hepatitis C: the South Australian state-wide experience.

AIM: The objective was to study the long-term (lifetime) cost effectiveness of four different hepatitis C virus (HCV) treatment models of care (MOC) with directly acting antiviral drugs. METHODS: A cohort Markov model-based probabilistic cost-effectiveness analysis (CEA) was undertaken extrapolating to up to 30 years from cost and outcome data collected from a primary study involving a real-life Australian cohort. In this study, noncirrhotic patients treated for HCV from 1 March 2016 to 28 February 2017 at four major public hospitals and liaising sites in South Australia were studied retrospectively. The MOC were classified depending on the person providing patient workup, treatment and monitoring into MOC1 (specialist), MOC2 (mixed specialist and hepatitis nurse), MOC3 (hepatitis nurse) and MOC4 (general practitioner, GP). Incremental costs were estimated from the Medicare perspective. Incremental outcomes were estimated based on the quality-adjusted life years (QALY) gained by achieving a sustained virological response. A cost-effectiveness threshold of Australian dollar 50 000 per QALY gained, the implicit criterion used for assessing the cost-effectiveness of new pharmaceuticals and medical services in Australia was assumed. Net monetary benefit (NMB) estimates based on this threshold were calculated. RESULTS: A total of 1373 patients, 64% males, mean age 50 (SD ±11) years, were studied. In the CEA, MOC4 and MOC2 clearly dominated MOC1 over 30 years with lower costs and higher QALYs. Similarly, NMB was the highest in MOC4, followed by MOC2. CONCLUSION: Decentralized care using GP and mixed consultant nurse models were cost-effective ways of promoting HCV treatment uptake in the setting of unrestricted access to new antivirals.

Validation of Knowledge Questionnaire for Patients With Liver Cirrhosis.

BACKGROUND & AIMS: There is no validated questionnaire to assess disease knowledge and self-management in patients with liver cirrhosis. We developed and validated a Cirrhosis Knowledge Questionnaire (CKQ). METHODS: We created a preliminary CKQ comprising 10 questions relevant to self-management of cirrhosis, based on publications and clinical experiences. The CKQ was given to a pilot sample of 17 patients with decompensated cirrhosis to assess its face validity. In consultation with experts, we developed a second version of CKQ, comprising 14 multiple choice questions, and administered it to 116 patients with cirrhosis participating in a Chronic Liver Failure Program. The dimensionality of the construct was assessed using exploratory factor analysis and internal consistency was assessed with Cronbach's alpha. Known-group validity of the resulting instrument was assessed by comparing the performance of the CKQ in 69 patients with decompensated cirrhosis (mean age, 62 ± 13 years; 109 responses), with (n = 42) vs without (n = 67) case management. RESULTS: A 3-factor model with 7 questions related to variceal bleeding, ascites, and hepatic encephalopathy was considered the optimal dimensionality with excellent internal consistency (Cronbach's alpha = 0.82). The mean knowledge score was higher in patients with case management (5.6 ± 1.1) than in patients without case management (4.3 ± 2.1) (P = .002). CONCLUSIONS: We developed and validated a questionnaire with 7 questions on ascites, variceal bleeding, and hepatic encephalopathy to assess knowledge and self-management in patients with liver cirrhosis. Studies are needed to confirm its dimensionality and assess association of scores with patient outcomes.

The impact of liver transplant recipient and donor genetic variability on tacrolimus exposure and transplant outcome.

This study investigated the effect of recipient and donor genetic variability on dose-adjusted steady-state tacrolimus concentrations (Css ) and clinical outcomes 3 and 6 months after liver transplant. Twenty-nine recipients and matched donor blood samples were genotyped for 27 single nucleotide polymorphisms including CYP3A5*3 (rs776746), ABCB1 haplotype and immune genes. Associations between genetic variability and clinical parameters and Css and the occurrence of rejection and nephrotoxicity were analysed by multivariate and multinomial logistic regression modelling and Jonckheere-Terpstra tests examined the impact of combined donor/recipient CYP3A5 expression on Css . At 3 months post-transplant modelling revealed an association between tacrolimus Css and recipient CASP1 rs580523 genotype (P = 0.005), accounting for 52% Css variance. Jonckheere-Terpstra tests revealed that as combined donor/recipient CYP3A5 expression increased, Css decreased (P = 0.010 [3 months], 0.018 [6 months]). As this is the first report of CASP1 genetic variability influencing tacrolimus Css , further validation in larger cohorts is required.

High rates of indeterminate interferon-gamma release assays for the diagnosis of latent tuberculosis infection in liver transplantation candidates.

BACKGROUND AND AIMS: Screening for latent tuberculosis infection (LTBI) is recommended prior to solid organ transplantation. Interferon-gamma release assays (IGRAs) are the most widely used test for LTBI screening; however, assessment of IGRA performance in patients with end-stage liver disease is limited. The purpose of this study was to evaluate the prevalence and predictors of indeterminate (INDT) IGRA results in liver transplantation candidates. METHODS: Between March 2011 and May 2018, we retrospectively analyzed 155 patients undergoing liver transplantation assessment, who underwent IGRA testing (Quantiferon-TB Gold, QFT-G) to exclude LTBI. Characteristics of patients, including age, gender, etiology of liver disease, MELD score, and absolute lymphocyte counts, were compared by QFT-G result (determinate vs INDT). RESULTS: Of the 155 patients screened, the rate of positive, negative, and INDT results were 5.2%, 69.8%, and 25%, respectively. The only variable independently associated with an indeterminate test on multivariate analysis was MELD score (odds ratio = 1.07, 95% CI = 1.01-1.14 per unit increase; P = 0.014). In 95% of INDT tests, both TB antigen tube and the positive control tube were negative and repeat testing gave the same indeterminate result, suggestive of anergy rather than laboratory error. CONCLUSIONS: Our study suggests a high rate of INDT IGRA results during screening of liver transplant candidates for LTBI, associated with severity of liver disease and anergy. Because of the high rate of INDT QFT-G testing in this setting, individualized risk assessment is required including a thorough assessment of clinical risk factors and knowledge of local TB prevalence.

Efficacy of High-Dose, Rapid, Hepatitis A and B Vaccination Schedules in Patients With Cirrhosis.

Patients with cirrhosis have increased morbidity from hepatitis A virus (HAV) and hepatitis B virus (HBV) infections, and vaccination against these infections is an important standard of care.1,2 However, vaccination in patients with cirrhosis is hindered by immune dysfunction and there is limited high-quality literature available. The aim of this work therefore was to compare immune responses of standard dose (SD) with high-dose accelerated (HDA) vaccination in cirrhotic patients.

Hepatitis C virus infection in Australian psychiatric inpatients: A multicenter study of seroprevalence, risk factors and treatment experience.

Screening and treatment for hepatitis C virus (HCV) infection were not prioritised in psychiatric patients due to adverse neuropsychiatric effects of interferon therapy despite reports of high prevalence. However, with the safe new antiviral drugs, HCV eradication has become a reality in these patients. The aim of this study was to report HCV seroprevalence, risk factors and treatment model in an Australian cohort. This prospective study involved patients admitted to four inpatient psychiatric units, from December 2016 to December 2017. After pretest counselling and consent, HCV testing was done; information on risk factors collected. A total of 260 patients (70% male), median age 44 years (IQR 24), were studied. The HCV seroprevalence was 10.8% (28/260) with 95% CI 7-15. Independent predictors of HCV positivity were injection drug use (P < 0.001, OR 44.05, 95% CI 7.9-245.5), exposure to custodial stay (P = 0.011, OR 7.34, 95% CI 1.6-33.9) and age (P = 0.011, OR 1.09, 95% CI 1.02-1.16). Eight of the 16 HCV RNA-positive patients were treated. Hepatitis nurses liaised with community mental health teams for treatment initiation and follow-up under supervision of hepatologists. Seven patients achieved sustained viral response, one achieved end of treatment response. The remaining eight patients were difficult to engage with. In conclusion, HCV prevalence was high in our cohort of psychiatric inpatients. Although treatment uptake was achieved only in 50% patients, it was successfully completed in all, with innovative models of care. These findings highlight the need to integrate HCV screening with treatment linkage in psychiatry practice.

Coordinated care for patients with cirrhosis: fewer liver-related emergency admissions and improved survival.

OBJECTIVES: To compare the incidence of liver-related emergency admissions and survival of patients after hospitalisation for decompensated cirrhosis at two major hospitals, one applying a coordinated chronic disease management model (U1), the other standard care (U2); to examine predictors of mortality for these patients. DESIGN: Retrospective observational cohort study. SETTING: Two major tertiary hospitals in an Australian capital city. PARTICIPANTS: Patients admitted with a diagnosis of decompensated cirrhosis during October 2013 - October 2014, identified on the basis of International Classification of Diseases (ICD-10) codes. MAIN OUTCOME MEASURES: Incident rates of liver-related emergency admissions; survival (to 3 years). RESULTS: Sixty-nine patients from U1 and 54 from U2 were eligible for inclusion; the median follow-up time was 530 days (range, 21-1105 days). The incidence of liver-related emergency admissions was lower for U1 (mean, 1.14 admissions per person-year; 95% CI, 0.95-1.36) than for U2 (mean, 1.55 admissions per person-year; 95% CI, 1.28-1.85; adjusted incidence rate ratio [U1 v U2], 0.52; 95% CI, 0.28-0.98; P = 0.042). The adjusted probabilities of transplantation-free survival at 3 years were 67.7% (U1) and 37.2% (U2) (P = 0.009). Independent predictors of reduced transplantation-free free survival were Charlson comorbidity index score (per point: hazard ratio [HR], 1.27; 95% CI, 1.05-1.54, P = 0.014), liver-related emergency admissions within 90 days of discharge (HR, 3.60; 95% CI, 1.87-6.92; P < 0.001), and unit (U2 v U1: HR, 2.54, 95% CI, 1.26-5.09; P = 0.009). CONCLUSIONS: A coordinated care model for managing patients with decompensated cirrhosis was associated with improved survival and fewer liver-related emergency admissions than standard care.

Raised plasma levels of H2S and nitrate predict intrapulmonary vascular dilations: A preliminary report in patients with cryptogenic cirrhosis.

BACKGROUND AND AIMS: The role of vasoactive chemicals in the pathogenesis of hepatopulmonary syndrome (HPS), a disorder characterized by intrapulmonary vascular dilation (IPVD), is only vaguely elucidated. We aimed to study the association between plasma H2S, nitrate levels, and presence and severity of IPVD and HPS. METHODS: Consecutive adult patients with cryptogenic cirrhosis were evaluated for IPVD (by contrast echocardiography) and for hypoxemia (by arterial blood gas analysis). Plasma H2S and nitrate levels were measured in these patients. RESULTS: Fifty-eight patients with cryptogenic cirrhosis (male, 45; median age, range, 45, 16-74 years; Child's class; A, 30; B, 18; C, 10) were enrolled in this study. Thirty-four of the 58 (59%) patients had IPVD and 13 (22%) had HPS (mild, 4; moderate, 5; severe, 2; very severe, 2). Plasma H2S levels were significantly higher in patients with IPVD (19.6, 5.7-83 µmol/L) as compared to patients who had no IPVD (12.3, 0-47 µmol/L; p-value 0.03) with an area under receiver operating characteristic curve of 0.68 (95% CI 0.53-0.84). Plasma H2S levels were higher in patients with IPVD irrespective of liver disease severity. There was a trend for higher plasma nitrate levels in patients with IPVD (47, 15.8-126.4 nmol/mL) as compared to patients who had no IPVD (32.3, 6.9-51.4 nmol/mL; p-value 0.1). Raised plasma H2S and nitrate levels had an additive effect on the presence of IPVD. Neither plasma H2S nor plasma nitrate levels correlated with the degree of hypoxemia. CONCLUSION: Raised plasma H2S and nitrate levels predict the presence of IPVD in patients with cryptogenic cirrhosis.
