Younossi Z, Henry L. Systematic review: patient-reported outcomes in chronic hepatitis C--the impact of liver disease and new treatment regimens. Aliment Pharmacol Ther 2015; 41:497-520. [PMID: 25616122 DOI: 10.1111/apt.13090] [Citation(s) in RCA: 112] [Impact Index Per Article: 12.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2014] [Revised: 11/07/2014] [Accepted: 01/03/2015] [Indexed: 12/18/2022]
Abstract
BACKGROUND Treatment for chronic hepatitis C (CH-C) is rapidly changing and moving away from an interferon and ribavirin-based therapy to interferon-free ribavirin-free all oral regimens. These regimens are simpler and shorter to administer with very high efficacy rates and better side effect profiles. As advances in the treatment of CH-C occur, it is imperative to capture both clinical outcomes (efficacy and safety) as well as patient-reported outcomes (PROs). In fact, PROs assesses and quantifies the impact of these regimens on patient experience. PROs assess patients' health-related quality of life (HRQOL) especially in the realms of fatigue and neuropsychiatric issues such as depression which can affect treatment adherence and work productivity. AIM To review the literature related to PRO's in HCV patients and summarise the impact of CH-C and its treatment on PROs. METHODS Databases Ovid MEDLINE and PubMed were searched from 1990 to October 2014 using a combination of MEsh, thesaurus terms and relevant text words: hepatitis C, CH-C, treatment, quality of life, health-related quality of life, fatigue, work productivity, adherence, patient-reported outcomes, direct acting anti-viral agents and second generation direct acting anti-viral agents. Each manuscript was assessed for pertinence to the issue of PROs in CH-C as well as the quality of study design and publications. RESULTS From the literature, it is evident that CH-C patients have baseline PRO impairment. Furthermore, treatment with interferon with or without ribavirin and first generation DAAs causes additional PRO burden which can negatively impact treatment adherence and indirectly, treatment efficacy and work productivity. The new treatment regimens with interferon- and ribavirin-free regimens not only have very high efficacy, but also result in the improvement of PRO scores as early as 2 weeks into treatment as well as possibly better adherence to treatment regimens. CONCLUSIONS CH-C and its treatment have been associated with patient-reported outcome impairment. The new IF-free and RBV-free regimens are associated with high efficacy and substantial improvement of patient-reported outcomes in clinical trial setting. Although very encouraging, more data are needed to assess patient-reported outcomes, adherence and work productivity of CH-C patients in the real world setting of clinical practice.

The Stroop smartphone application is a short and valid method to screen for minimal hepatic encephalopathy. Hepatology 2013; 58:1122-32.

Abstract
UNLABELLED Minimal hepatic encephalopathy (MHE) detection is difficult because of the unavailability of short screening tools. Therefore, MHE patients can remain undiagnosed and untreated. The aim of this study was to use a Stroop smartphone application (app) (EncephalApp_Stroop) to screen for MHE. The app and standard psychometric tests (SPTs; 2 of 4 abnormal is MHE, gold standard), psychometric hepatic encephalopathy score (PHES), and inhibitory control tests (ICTs) were administered to patients with cirrhosis (with or without previous overt hepatic encephalopathy; OHE) and age-matched controls from two centers; a subset underwent retesting. A separate validation cohort was also recruited. Stroop has an "off" state with neutral stimuli and an "on" state with incongruent stimuli. Outcomes included time to complete five correct runs as well as number of trials needed in on (Ontime) and off (Offtime) states. Stroop results were compared between controls and patients with cirrhosis with or without OHE and those with or without MHE (using SPTs, ICTs, and PHES). Receiver operating characteristic analysis was performed to diagnose MHE in patients with cirrhosis with or without previous OHE. One hundred and twenty-five patients with cirrhosis (43 previous OHE) and 134 controls were included in the original cohort. App times were correlated with Model for End-Stage Liver Disease (Offtime: r = 0.57; Ontime: r = 0.61; P < 0.0001) and were worst in previous OHE patients, compared to the rest and controls. Stroop performance was also significantly impaired in those with MHE, compared to those without MHE, according to SPTs, ICTs, and PHES (all P < 0.0001). A cutoff of >274.9 seconds (Ontime plus Offtime) had an area under the curve of 0.89 in all patients and 0.84 in patients without previous OHE for MHE diagnosis using SPT as the gold standard. The validation cohort showed 78% sensitivity and 90% specificity with the >274.9-seconds Ontime plus Offtime cutoff. App result patterns were similar between the centers. Test-retest reliability in controls and those without previous OHE was good; a learning effect on Ontime in patients with cirrhosis without previous OHE was noted. CONCLUSION The Stroop smartphone app is a short, valid, and reliable tool for screening of MHE.

Loss of tyrosine hydroxylase expression within the nigro-striato-cortical pathways in the cirrhotic rat: the possible restorative effect of the neurosteroid dehydroepiandrosterone sulfate. Acta Histochem 2013; 115:637-45. [PMID: 23453752 DOI: 10.1016/j.acthis.2013.01.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2012] [Revised: 01/21/2013] [Accepted: 01/23/2013] [Indexed: 12/25/2022]
Abstract
Hepatic encephalopathy (HE) is a neuropsychiatric disorder occurring as a consequence of both acute and chronic liver failure. Advanced HE is generally accompanied with extrapyramidal symptoms including rigidity and tremor, which may reflect alterations of the dopaminergic system. Recently we reported a beneficial effect of the neuroactive steroid dehydroepiandrosterone sulfate (DHEAS) in cirrhotic rats, however the mechanisms of such an effect by DHEAS were not addressed. In the present study, we describe the changes of the dopaminergic system occurring in the cirrhotic rats and concomitantly we investigated the effect of DHEAS on this system in Sprague-Dawley rats using the expression of tyrosine hydroxylase (TH) as a neuronal marker. Rats were submitted to bile duct ligation (BDL) surgery and TH immunohistochemistry was assessed in the Substantia nigra pars compacta (SNc), striatum, ventral tegmental area (VTA) and the cortex. TH immunoreactivity showed a significant diminution in both SNc and VTA concomitantly with the cortical and the striatal outputs in the BDL rats vs. controls. Three daily injections of 5mg/kg of DHEAS to BDL rats significantly normalized TH expression decrease in both SNc and VTA as well as dopaminergic projections to the striatum and the cortex of BDL rats. The present data support an involvement of the dopaminergic system in mild HE and a possible beneficial effect of the neurosteroid DHEAS as a potential pharmacological treatment of mild HE.

Abstract
BACKGROUND Hepatic encephalopathy (HE) is a brain disorder that often results from cirrhosis due to viral hepatitis, metabolic and alcohol-related liver disease, and is characterised by cognitive, psychiatric and motor impairments. Recurrent bouts of overt HE negatively impact daily functioning and quality of life. AIM To evaluate the effect of rifaximin on health-related quality of life (HRQL) in cirrhotic patients with HE. METHODS Patients with cirrhosis in remission from HE (Conn score = 0 or 1) and a documented history of recurrent HE episodes (≥2 within 6 months of screening) were randomised to rifaximin 550 mg twice daily (N = 101) or placebo (N = 118) for 6 months. Concomitant lactulose was permitted during the study. The Chronic Liver Disease Questionnaire (CLDQ) was administered every 4 weeks, and time for occurrence of HE breakthrough was recorded. A longitudinal analysis using time-weighted averages of the CLDQ scores normalised by days on study therapy was used to evaluate the effect of treatment on HRQL, and between HE outcomes (HE recurrence, yes/no) irrespective of treatment. RESULTS The time-weighted averages of the overall CLDQ score and each domain score were significantly higher in the rifaximin group vs. placebo (P-values ranged from 0.0087 to 0.0436); and were significantly lower in patients who experienced HE breakthrough compared to those who remained in remission (P-values were <0.0001). CONCLUSION Rifaximin significantly improved HRQL in patients with cirrhosis and recurrent hepatic encephalopathy. A lower HRQL may predict recurrence of hepatic encephalopathy.
