RESUMO

AIMS AND OBJECTIVES: This study aimed to explore the experiences of liver transplant recipients during their journey through the treatment and their need for psychotherapeutic support related to this process. BACKGROUND: Over time, measures of survival and quality of life in liver transplant recipients have continued to improve but their emotional needs remain under explored. In the longer-term recovery from transplantation, the focus shifts from physical health to psychological health. In the UK, there are no known embedded adult psychological services in liver transplant centres to react to this need. DESIGN: A qualitative descriptive design was used. METHODS: Grounded theory analysis was used to study the narratives of six adult liver transplant recipients. Through a process of coding, conceptual categories were established to describe the participant experiences. The study adhered to the EQUATOR checklist, SRQR. RESULTS: Four categories emerged that were related to the experience of liver transplantation for the recipients. These were a process of adjustment, the phenomenon of waiting, liver transplant as a transformative experience and on the value of support. The participants identified a lack of psychotherapeutic support provided by the liver transplant service and felt that an embedded psychotherapeutic service would promote accessing such support during challenging times. CONCLUSION: Through the process of liver transplantation, recipients experience challenges with adjustment, waiting, feeling transformed and they value support with these feelings. In correlation with other studies, the findings of this study highlight the need for providing psychotherapeutic support within liver transplant services. RELEVANCE TO CLINICAL PRACTICE: The study provides evidence to support recommendations for a conjoined psychotherapy service within liver transplant services to support patients with their holistic needs.

RESUMO

OBJECTIVE: Sorafenib is the standard of care for patients with advanced hepatocellular carcinoma (HCC), but data on its use in the elderly are inconclusive. METHODS: All consecutive HCC patients who were treated in our institution with sorafenib since its licensing were included in the analysis. Patients were divided into two groups: (A) up to 75 and (B) older than 75 years old. Our endpoints were overall survival (OS) and time to treatment failure (TTF) because of disease progression or toxicity. Safety parameters and the prognostic effect of HCC characteristics were also investigated. RESULTS: Data from 190 patients (157 men), median age 66 (26-87) years, were studied (A=151 and B=39). No significant difference in OS and TTF was detected between the two groups [7.1 (5.5-8.7) vs. 10.4 (6.5-14.3) months, P=0.360 and 4.2 (2.3-6.2) vs. 5.6 (3.1-8.1) months, P=0.369, respectively]. Incidence of toxicities at all grades and dose reductions were comparable between groups A and B. In a multivariate setting, patients with Child-Pugh B score at baseline were associated with a higher risk of death (adjusted hazard ratio=2.17, 95% confidence interval:1.24-3.79, P=0.007) and treatment failure (adjusted hazard ratio=4.64, 95% confidence interval: 2.55-8.42, P=0.001) and had shorter OS and TTF compared with patients with a Child-Pugh A (P=0.004 and P<0.001, respectively). CONCLUSION: Elderly patients with advanced HCC, when treated with sorafenib, have an equivalent clinical outcome with similar toxicity rates as their younger counterparts. Age alone should not be a discriminating factor for the management of advanced HCC with sorafenib.

RESUMO

Young people (YP) with chronic illness have higher rates of mental health problems than the general population, with psychosocial complexity associated with nonadherence and poorer health outcomes. This study aimed to describe the prevalence of anxiety and depression in YP after liver transplantation, with autoimmune liver disease and other chronic liver diseases, identify the factors YP attribute their distress to and the relationship between anxiety/depression, and describe YP's beliefs about their illness and treatment. An electronically administered questionnaire battery was given routinely to YP attending an outpatient liver transition clinic; 187 YP participated, of which 17.7% screened positive for anxiety or depression. There were no significant differences between disease groups. This is significantly higher than the prevalence of common mental health problems in the general adolescent population. Patients most frequently attributed their distress to fatigue, sleep difficulties, financial concerns, problems at work/school, worry, and low self-esteem. Higher levels of depression and anxiety were significantly associated with specific illness and treatment beliefs but not with perceived understanding of illness or treatment control. In conclusion, the increased prevalence of mental health problems in YP and the intertwined nature of these with their physical health outcomes provide evidence that holistic care should be delivered as standard for this age group.

RESUMO

The first application of high field NMR spectroscopy (800 MHz for (1)H observation) to human hepatic bile (as opposed to gall bladder bile) is reported. The bile sample used for detailed investigation was from a donor liver with mild fat infiltration, collected during organ retrieval prior to transplantation. In addition, to focus on the detection of bile acids in particular, a bile extract was analysed by 800 MHz (1)H NMR spectroscopy, HPLC-NMR/MS and UPLC-MS. In the whole bile sample, 40 compounds have been assigned with the aid of two-dimensional (1)H-(1)H TOCSY and (1)H-(13)C HSQC spectra. These include phosphatidylcholine, 14 amino acids, 10 organic acids, 4 carbohydrates and polyols (glucose, glucuronate, glycerol and myo-inositol), choline, phosphocholine, betaine, trimethylamine-N-oxide and other small molecules. An initial NMR-based assessment of the concentration range of some key metabolites has been made. Some observed chemical shifts differ from expected database values, probably due to a difference in bulk diamagnetic susceptibility. The NMR spectra of the whole extract gave identification of the major bile acids (cholic, deoxycholic and chenodeoxycholic), but the glycine and taurine conjugates of a given bile acid could not be distinguished. However, this was achieved by HPLC-NMR/MS, which enabled the separation and identification of ten conjugated bile acids with relative abundances varying from approximately 0.1% (taurolithocholic acid) to 34.0% (glycocholic acid), of which, only the five most abundant acids could be detected by NMR, including the isomers glycodeoxycholic acid and glycochenodeoxycholic acid, which are difficult to distinguish by conventional LC-MS analysis. In a separate experiment, the use of UPLC-MS allowed the detection and identification of 13 bile acids. This work has shown the complementary potential of NMR spectroscopy, MS and hyphenated NMR/MS for elucidating the complex metabolic profile of human hepatic bile. This will be useful baseline information in ongoing studies of liver excretory function and organ transplantation.

RESUMO

Increasing rates of success in liver transplantation have increased the number of cases considered. However, liver post-transplant graft dysfunction of liver transplants (TXs) is not fully understood and by applying holistic approaches we can investigate metabolic change deriving from confounding factors such as liver fat content, ischaemia time, donor age, recipient's health, etc. Twenty-six hepatic bile samples taken from liver donors and recipients were retrieved from a total of six TXs, from these one recipient underwent post-graft dysfunction. CE was employed to fingerprint bile collected at 10 min increments in the donors and in the recipients. The electropherograms of these samples were aligned and normalised using correlation optimised warping algorithms and modelled with multivariate techniques. The resulting metabolic signatures were compared; in general donors and recipients showed distinct fingerprints and clustered separately. When a partial least square discriminant analysis (PLS-DA) model was constructed between donor and recipient's samples, a recipient of a 32 year old liver with normal steatosis, and shortest cold ischaemia time showed as the observation nearest to its donor observation, denoting minimal metabolic change. This study proposes CE fingerprinting of human bile as a promising technique to help unravel the complex metabolic pathways involved during transplantation.

RESUMO

BACKGROUND: Adult orthotopic liver transplantation is associated with significant use of allogenic blood products, which places considerable demands on finite resources. This could be reduced by autologous red cell salvage use, and we evaluated its cost effectiveness in this prospective study. METHODS: Intraoperative autotransfusion was used in 660 adult liver transplant patients between January 1997 and July 2002. These included 134 with acute liver failure, 62 retransplants, 90 alcohol-related, 183 viral, 98 cholestatic chronic liver diseases, and 93 with other etiologies. RESULTS: The total volume of red blood cells transfused was 3641+/-315 ml, 2805+/-234 ml, 2603+/-443 ml, and 2785+/-337 ml for alcohol-related, viral, cholestatic, and others, respectively. Low preoperative hemoglobin was significantly associated with higher intraoperative transfusion requirements. Blood volumes transfused at retransplantation were significantly higher (7077+/-1110 ml vs. 2864+/-138 ml; P<0.001) than for acute liver failure and chronic liver disease. Autologous blood volumes transfused were similar in all diagnostic groups, but were significantly greater in retransplantation (2754+/-541 ml vs. 1524+/-77 ml; P<0.01). Venovenous bypass was significantly associated with higher transfusion requirements. Total savings per case were similar for all diagnostic groups but were greater in cases of retransplantation (864+/-222 pounds (1235+/-317 US dollars) vs. 238+/-24 pounds (340+/-34 US dollars; P<0.001). With the use of autologous transfusion over the study period, a cost saving of 131,901 pounds (188,618 US dollars) was achieved. CONCLUSIONS: Intraoperative red blood cell salvage and autologous transfusion is cost effective in adult liver transplantation. Currently, where optimum resource utilization and fiscal constraint are paramount in healthcare delivery, autologous transfusion is an important adjunct in liver transplantation.
