Integrative Review of Co-Occurring Symptoms Across Etiologies of Chronic Liver Disease and Implications for Symptom Management Research and Practice

Distinct Longitudinal Trajectories of Symptom Burden Predict Clinical Outcomes in End-Stage Liver Disease

INTRODUCTION

Little has been reported about the clinical relevance and trajectories of symptoms in end-stage liver disease (ESLD). The purpose of this prospective study was to identify trajectories of change in symptom burden over the course of 12 months in adults with ESLD.

METHODS

Patients were recruited from hepatology clinics at 2 healthcare systems. Validated measures were used to assess physical and psychological symptoms. Latent growth mixture modeling and survival and growth modeling were used to analyze the survey data.

RESULTS

Data were available for 192 patients (mean age 56.5 ± 11.1 years, 64.1% male, mean Model for ESLD (MELD) 3.0 19.2 ± 5.1, ethyl alcohol as primary etiology 33.9%, ascites 88.5%, encephalopathy 70.8%); there were 38 deaths and 39 liver transplantations over 12 months. Two symptom trajectories were identified: 62 patients (32.3%) had high and unmitigated symptoms, and 130 (67.7%) had lower and improving symptoms. Patients with high and unmitigated symptoms had twice the hazard of all-cause mortality (subhazard ratio 2.53, 95% confidence interval: 1.32-4.83) and had worse physical ( P < 0.001) and mental quality of life ( P = 0.012) compared with patients with lower and improving symptoms. Symptom trajectories were not associated with MELD 3.0 scores ( P = 0.395). Female sex, social support, and level of religiosity were significant predictors of symptom trajectories ( P < 0.05 for all).

DISCUSSION

There seems to be 2 distinct phenotypes of symptom experience in patients with ESLD that is independent of disease severity and associated with sex, social support, religiosity, and mortality. Identifying patients with high symptom burden can help optimize their care.

A qualitative patient interview study to understand the experience of patients with nonalcoholic steatohepatitis

NASH is a potentially progressive form of NAFLD characterized by hepatocyte injury and liver inflammation which can cause fibrosis. Currently, there are limited data on the patient experience of NASH. Our aim was to use both literature review and patient interviews to understand the signs/symptoms and life impacts of NASH fibrosis stages F1-F4 that are important to patients, as well as begin to investigate the applicability of an instrument (ie, questionnaire) that may be used to capture patients' experiences. The literature review identified concepts (signs/symptoms and impacts) related to NASH fibrosis stages F1-F4 and the NASH-specific patient-reported outcome instrument (NASH-CHECK) for reporting patient experience of NASH. Interviews with 22 patients from Canada and the USA with NASH fibrosis stages F1-F4 revealed 27 signs/symptoms and 32 impacts that they felt were important, including fatigue, pain in the abdomen, worry, and frustration. Three concepts reported during patient interviews were not identified in the literature review. No concepts appeared to be exclusive to a specific fibrosis stage or presence/absence of obesity and no linear trends were identified between fibrosis stage or presence/absence of obesity and level of disturbance reported for concepts. The patient interviews supported the concepts included in the NASH-CHECK overall, demonstrating that it could be used to report the patient experience of NASH fibrosis stages F1-F4. Interviews with patients with NASH fibrosis stages F1-F4 revealed patients can self-report and elaborate on signs/symptoms and impacts related to the disease regardless of fibrosis stage. The NASH-CHECK was identified as a suitable instrument that could be used by patients with fibrosis stages F1-F4.

Symptom Classes in Decompensated Liver Disease

BACKGROUND & AIMS

Patients with decompensated liver disease have been categorized by disease severity. This analysis sought to classify patients with end-stage liver disease based on symptoms rather than disease state and to identify distinct severity classes of physical and psychological symptoms.

METHODS

Patients with a model for end-stage liver disease-sodium score of 15 or higher were recruited from liver clinics in 2 health care organizations. They completed the Condensed Memorial Symptom Assessment Scale, Revised Ways of Coping Checklist, Patient Health Questionnaire, Life Orientation Test-Revised, and the Short-Form Health Survey. Cross-sectional data were analyzed using latent class mixture modeling.

RESULTS

The sample (N = 191; age, 56.6 ± 11.1 y; 33.5% ETOH; 28.3% nonalcoholic fatty liver disease; 13.1% autoimmune/primary biliary cholangitis/primary sclerosing cholangitis) was predominantly male (64.2%), Child-Turcotte-Pugh class C (49.5%), with an average model for end-stage liver disease-sodium score of 18.7 ± 4.9. Three distinct classes of symptoms were identified, as follows: mild (26.7%), moderate (41.4%), or severe (31.9%) symptoms. Symptom classes were independent of disease severity and demographic characteristics, except age. All Condensed Memorial Symptom Assessment Scale symptoms and Patient Health Questionnaire scores were significantly different across the 3 classes (P < .05). The symptom classes also differed significantly in physical and mental quality of life, optimism, and avoidance coping behaviors (all P < .001).

CONCLUSIONS

Patient-reported symptom severity occurred independent of disease severity, contrary to common assumptions. Focusing on the moderate and severe symptom classes as well as patient history of end-stage liver disease complications may enhance providers' ability to improve symptom management for this population.

Home-care nurses' community involvement activities and preference regarding the place for end-of-life period among single older adults: A cross-sectional study in Japan

Older adults' preference regarding where they want to spend their end-of-life (EOL) has been reported to be a significant predictor of the actual EOL location. Home-care nurses have often been reported to try involving single older adults' neighbours in the support network of the older adults (community involvement activities) to allow them to stay at home. Hence, nurses' community involvement activities may be among the significant factors of older adults' preference to stay at home during EOL. Therefore, this study explored home-care nurses' community involvement activities and its association with single older adults' EOL preference. A cross-sectional questionnaire survey was conducted with older adults (aged 65 years or older) who lived alone and used home-care nursing services for more than 6 months, their home-care nurses, and managers of their home-care nursing agencies. Questions included participants' characteristics, nurses' community involvement activities and older adults' preference to remain at home during EOL. We conducted multiple logistic regression analyses to explore the relationship between nurses' community involvement activities and older adults' preference to remain at home during EOL while controlling for their demographic variables. In total, 103 pairs of home-care nurses and single older adults from 27 home-care nursing agencies participated. Approximately 70% of older adults preferred to remain at home during EOL, and 50% of nurses implemented community involvement activities. Older adults' preference to remain at home during EOL was associated with implementation of community involvement activities (Odds Ratio [OR]: 3.4; 95% Confidence Interval [95%CI]:1.1-9.8), home-care nurses' higher practical clinical ability (OR: 1.4, 95%CI:1.0-1.8), and older adult's longer use of home-care nursing service (OR: 2.2, 95%CI:1.2-4.1). Community involvement activities may be essential in helping single older adults to stay at home as per their preference for EOL.

AGA Clinical Practice Update on Palliative Care Management in Cirrhosis: Expert Review

Care with palliative care principles (aka Palliative Care, PC) is an approach to care that focuses on improving the quality of life of patients and their caregivers who are facing life-limiting illness. It encompasses the assessment and management of symptoms and changes in functional status, the provision of advance care planning and goals of care discussions, prognostication and caregiver support. PC is applicable across the spectrum of cirrhosis regardless of transplant eligibility. Although a common misconception, PC is not synonymous with hospice care. Unfortunately, despite a high symptom burden and challenges with predicting disease course and mounting evidence to support the benefits of PC in patients with cirrhosis, comprehensive PC and referral to hospice are carried out infrequently and very late in the course of disease. In order to meet the needs of our increasingly prevalent cirrhosis population, it is important that all clinicians who care for these patients are able to work together to deliver PC as a standard of care. To date there are limited guidelines/guidance statements to direct clinicians in the area of PC and cirrhosis. Herein we present an evidence-based review of ten Best Practice Advice statements that address key issues pertaining to PC in patients with cirrhosis.

PBC-10: a short quality of life measure for clinical screening in primary biliary cholangitis

BACKGROUND

Current guidelines in primary biliary cholangitis ( PBC) recommend routine screening for symptoms. However, at present there are no validated practical tools suitable for screening use in practice.

AIM

To develop a short quality of life questionnaire for PBC METHODS: The short PBC HRQL questionnaire was derived and validated by analysing the PBC-40 questionnaires from the UK-PBC Research Cohort. Construct validity was assessed using the European Quality of Life Five Dimensions (EQ5D) questionnaire. Test-retest analysis was done by asking a subgroup of patients to complete the questionnaire twice within 2-4 weeks.

RESULTS

A total of 2219 patients completed PBC-40 questionnaire in 2013. Stepwise regression identified 10 questions that contributed to more than 95% of the PBC-40 score variance and covered the main domains of PBC. The short HRQL questionnaire, PBC-10, had good internal consistency (Cronbach's α 0.905) and item-total correlations. PBC-10 demonstrated no ceiling effects but a floor effect was noted. Further validation on 2502 patients who completed the PBC questionnaire in 2017 confirmed the psychometric properties of PBC-10. Further analysis on 186 patients showed that PBC-10 demonstrated good internal consistency (Cronbach's α = 0.936), had good reproducibility (intra-class correlation coefficient = 0.945), good correlation with the EQ5D (r = .736), and was responsive to change. A change of 4 points in the PBC-10 score would be considered clinically important.

CONCLUSION

PBC-10 is a short and valid questionnaire for assessing the HRQL in patients with PBC in clinical practice.

Association of CTRP13 With Liver Enzymes and Cognitive Symptoms in Nonalcoholic Fatty Liver Disease

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease in which patients present with metabolic dysregulation and obesity as well as fat accumulation in the liver. Those with NAFLD frequently have symptoms of fatigue, sleep disturbance, depression, and cognitive dysfunction. C1q/TNF-related protein 13 (CTRP13) regulates glucose metabolism and obesity in mice, yet the role of CTRP13 in human NAFLD has not been elucidated.

AIMS

Our aims were to examine whether the plasma levels of CTRP13 are (a) increased in patients with NAFLD; (b) associated with metabolic dysregulation, obesity, liver enzymes, and dyslipidemia; and (c) associated with putative symptoms of NAFLD.

METHODS

An observational study was conducted with 23 adults with confirmed NAFLD. Plasma levels of CTRP13, insulin resistance, insulin sensitivity, HbA1C, lipid profile, and liver enzymes were collected. Anthropometric analysis (body mass index, waist-hip circumference ratio) and bioelectrical impedance analysis of body composition were used to assess obesity. Symptom questionnaires were used to assess putative symptoms of NAFLD. Plasma levels of CTRP13 were measured in 21 age- and sex-matched control samples from a biobank. Paired t test was used for comparison of the CTRP13 between NAFLD and controls. Pearson's correlation coefficients were used to examine associations among variables.

RESULTS

Plasma levels of CTRP13 were significantly higher in patients with NAFLD than in normal controls (p < .001), were associated with higher levels of aspartate aminotransferase, alanine aminotransferase (both p < .05), triglycerides (p < .001), and poorer cognitive function, particularly visuospatial memory (p < .001).

CONCLUSIONS

CTRP13 may be a surrogate biomarker of NAFLD symptoms and associated with hepatocellular damage, dyslipidemia, and cognitive dysfunction.

Fatigue in chronic liver disease: New insights and therapeutic approaches

The management of fatigue associated with chronic liver disease is a complex and major clinical challenge. Although fatigue can complicate many chronic diseases, it is particularly common in diseases with an inflammatory component. Fatigue can have both peripheral (i.e., neuromuscular) and central (i.e., resulting from changes in neurotransmission within the brain) causes. However, fatigue in chronic liver disease has strong social/contextual components and is often associated with behavioural alterations including depression and anxiety. Given the increasing awareness of patient-reported outcomes as important components of treatment outcomes and clinical research, there is a growing need to better understand and manage this poorly understood yet debilitating symptom. Although several pathophysiological mechanisms for explaining the development of fatigue have been generated, our understanding of fatigue in patients with chronic liver disease remains incomplete. A better understanding of the pathways and neurotransmitter systems involved may provide specific directed therapies. Currently, the management of fatigue in chronic liver disease can involve a combined use of methods to beneficially alter behavioural components and pharmacological interventions, of which several treatments have potential for the improved management of fatigue in chronic liver disease. However, evidence and consensus are lacking on the best approach and the most appropriate biochemical target(s) whilst clinical trials to address this issue have been few and limited by small sample size. In this review, we outline current understanding of the impact of fatigue and related symptoms in chronic liver disease, discuss theories of pathogenesis, and examine current and emerging approaches to its treatment.

Palliative care in end-stage liver disease: Time to do better?

Optimal involvement of palliative care (PC) services in the management of patients with decompensated cirrhosis and end-stage liver disease (ESLD) is limited. This may result from both ignorance and the failure to recognize the spectrum and unpredictability of the underlying liver condition. Palliative care is a branch of medicine that focuses on quality of life (QoL) by optimizing symptom management and providing psychosocial, spiritual, and practical support for both patients and their caregivers. Historically, palliative care has been underutilized for patients with decompensated liver disease. This review provides an evidence-based analysis of the benefits of the integration of palliative care into the management of patients with ESLD. Liver Transplantation 24 961-968 2018 AASLD.

Fatigued Patients with Chronic Liver Disease Have Subtle Aberrations of Sleep, Melatonin and Cortisol Circadian Rhythms

AIMS

We sought to examine whether disturbances in central and peripheral circadian rhythms were related to the experience of fatigue in patients with chronic liver disease (CLD).

METHODS

Fatigued and non-fatigued patients with compensated CLD were enrolled in a prospective pilot study. Patients underwent a one week evaluation of free-living sleep and physical activity patterns, followed by a 24-hour admission, during which they underwent serial blood sampling, polysomnography, a 6-minute walk test and continuous core temperature measurements under standardized conditions. Blood samples were analyzed for liver tests, melatonin levels, lipids, and cortisol. Circadian rhythms were analyzed using single cosinor analyses.

RESULTS

Six fatigued and six non-fatigued patients were studied; five participants had cirrhosis. Fatigue severity was positively associated higher peak melatonin levels (rho=0.59, p=0.04) and a delay in night-time melatonin peak and inversely associated with sleep efficiency (rho=-0.63, p=0.04). Polysomnography, 6-minute walk test, and core temperature measurements did not differ significantly between the fatigued and non-fatigued patients. Although liver enzymes, bilirubin and albumin demonstrated a circadian pattern, it was not associated with fatigue. Fatigued patients showed a blunted and delayed cortisol rhythm and fatigue was strongly correlated with cortisol amplitude (rho=-0.77, p=0.004) and phase (r=-0.66, p=0.02).

CONCLUSION

Subtle aberrations in melatonin and adrenal circadian rhythms, as well as reduced sleep efficiency, likely contribute to fatigue in patients with CLD. These abnormalities may ultimately be a therapeutic target to improve quality of life for fatigued patients with CLD.

Assessment of Educational Needs and Quality of Life of Chronic Hepatitis Patients

Background

Patient education is crucial in improving the health-related quality of life (HRQOL) of patients. At the same, understanding the concerns and needs of patients is essential in providing appropriate education. This study assessed the educational needs and HRQOL experienced by chronic hepatitis patients.

Methods

We developed structured questionnaires with satisfactory validity and reliability to assess the educational needs of patients. HROQL was measured using a generic Short Form 36 (SF-36) and a liver disease-specific Chronic Liver Disease Questionnaire (CLDQ). Descriptive statistic measures and Pearson’s correlation analysis were applied for data analysis.

Results

A total of 135 subjects were recruited from two regional teaching hospitals in Taiwan. “Disease characteristics and management” exhibited the highest mean score (3.17) among all the subscales of educational needs. In comparison with those without antiviral therapy, chronic hepatitis patients undergoing antiviral treatment scored significantly higher on all subscales of educational needs, especially on “side effects of antiviral treatment” (p < 0.010). The median range of the physical component summary score was 45.94, the mental component summary score was 49.37, and the mean CLDQ was 5.70. Several domains of educational needs were significantly inversely correlated with the CLDQ and SF-36 subscales.

Conclusions

Education is highly required by chronic hepatitis patients, especially those receiving antiviral therapy and patients with poor HRQOL. These findings can serve as a useful reference for nursing personnel who perform needs assessment to develop individual nursing instruction and thereby improve the quality of care for chronic hepatitis patients.
