RESUMO
BACKGROUND AND AIMS: Pre-liver transplant (LT) functional status is an important determinant of prognosis post LT. There is insufficient data on how functional status affects outcomes of transplant recipients based on the specific etiology of liver disease. We stratified LT recipients by etiology of liver disease to evaluate the effects of functional status on post-LT prognosis in each subgroup. METHODS: 2005-2019 United Network for Organ Sharing (UNOS) Standard Transplant Analysis and Research (STAR) was used to select patients with liver transplant. A total of 14,290 patients were included in the analysis. These patients were stratified by functional status according to Karnofsky Performance Scale (KPS) score: no assistance, some assistance, or total assistance. They were then further divided into six diagnosis categories: metabolic dysfunction-associated steatotic liver disease (MASLD), hereditary disorders, hepatitis C, hepatitis B, autoimmune disease (AID), and alcoholic liver disease (ALD). Primary endpoints included all-cause mortality and graft failure, while secondary endpoints included organ-specific causes of death. Those under the age of 18 and those with non-whole liver or prior liver transplantation were excluded. RESULTS: Patients with MASLD requiring some assistance (aHR: 1.57, 95% CI 1.03-2.39, p = 0.04) and those requiring total assistance (aHR: 2.32, 95% CI 1.48-3.64, p < 0.001) had higher incidences of graft failure compared to those requiring no assistance. Those with MASLD requiring total assistance had a higher all-cause mortality rate than those needing no assistance (aHR: 1.62, 95% CI 1.38-1.89, p < 0.001). Patients with hereditary causes of liver disease showed a lower incidence of all-cause mortality in recipients needing some assistance compared with those needing no assistance (aHR: 0.52, 95% CI 0.34-0.80, p = 0.003). LT recipients with hepatitis C, AID, and ALD all showed higher incidences of all-cause mortality in the total assistance cohort when compared to the no assistance cohort. For the secondary endpoints of specific cause of death, transplant recipients with MASLD needing total assistance had higher rates of death due to general cardiac causes, graft rejection, general infectious causes, sepsis, general renal causes, and general respiratory causes. CONCLUSION: Patients with MASLD cirrhosis demonstrated the worst overall outcomes, suggesting that this population may be particularly vulnerable. Poor functional status in patients with end-stage liver disease from hepatitis B or hereditary disease was not associated with a significantly increased rate of adverse outcomes, suggesting that the KPS score may not be broadly applicable to all patients awaiting LT.
RESUMO
BACKGROUND AND AIMS: This study evaluates the cost burdens of inpatient care for chronic hepatitis B (CHB). We aimed to stratify the patients based on the presence of cirrhosis and conduct subgroup analyses on patient demographics and medical characteristics. METHODS: The 2016-2019 National Inpatient Sample was used to select individuals diagnosed with CHB. The weighted charge estimates were derived and converted to admission costs, adjusting for inflation to the year 2016, and presented in United States Dollars. These adjusted values were stratified using select patient variables. To assess the goodness-of-fit for each trend, we graphed the data across the respective years, expressed in a chronological sequence with format (R2, p-value). Analysis of CHB patients was carried out in three groups: the composite CHB population, the subset of patients with cirrhosis, and the subset of patients without cirrhosis. RESULTS: From 2016 to 2019, the total costs of hospitalizations in CHB patients were $603.82, $737.92, $758.29, and $809.01 million dollars from 2016 to 2019, respectively. We did not observe significant cost trends in the composite CHB population or in the cirrhosis and non-cirrhosis cohorts. However, we did find rising costs associated with age older than 65 (0.97, 0.02), white race (0.98, 0.01), Hispanic ethnicity (1.00, 0.001), and Medicare coverage (0.95, 0.02), the significance of which persisted regardless of the presence of cirrhosis. Additionally, inpatients without cirrhosis who had comorbid metabolic dysfunction-associated steatotic liver disease (MASLD) were also observed to have rising costs (0.96, 0.02). CONCLUSIONS: We did not find a significant increase in overall costs with CHB inpatients, regardless of the presence of cirrhosis. However, certain groups are more susceptible to escalating costs. Therefore, increased screening and nuanced vaccination planning must be optimized in order to prevent and mitigate these growing cost burdens on vulnerable populations.

BACKGROUND AND AIMS: The presence of steatosis in a donor liver and its relation to post-transplantation outcomes are not well defined. This study evaluates the effect of the presence and severity of micro- and macro-steatosis of a donor graft on post-transplantation outcomes. METHODS: The UNOS-STAR registry (2005-2019) was used to select patients who received a liver transplant graft with hepatic steatosis. The study cohort was stratified by the presence of macro- or micro-vesicular steatosis, and further stratified by histologic grade of steatosis. The primary endpoints of all-cause mortality and graft failure were compared using sequential Cox regression analysis. Analysis of specific causes of mortality was further performed. RESULTS: There were 9184 with no macro-steatosis (control), 150 with grade 3 macro-steatosis, 822 with grade 2 macro-steatosis and 12 585 with grade 1 macro-steatosis. There were 10 320 without micro-steatosis (control), 478 with grade 3 micro-steatosis, 1539 with grade 2 micro-steatosis and 10 404 with grade 1 micro-steatosis. There was no significant difference in all-cause mortality or graft failure among recipients who received a donor organ with any evidence of macro- or micro-steatosis, compared to those receiving non-steatotic grafts. There was increased mortality due to cardiac arrest among recipients of a grade 2 macro-steatosis donor organ. CONCLUSION: This study shows no significant difference in all-cause mortality or graft failure among recipients who received a donor liver with any degree of micro- or macro-steatosis. Further analysis identified increased mortality due to specific aetiologies among recipients receiving donor organs with varying grades of macro- and micro-steatosis.

BACKGROUND AND AIM: In this study, we used a national cohort of patients with Wilson's disease (WD) to investigate the admissions, mortality rates, and costs over the captured period to assess specific subpopulations at higher burden. METHODS: Patients with WD were selected using 2016-2019 National Inpatient Sample (NIS). The weighted estimates and patient data were stratified using demographics and medical characteristics. Regression curves were graphed to derive goodness-of-fit for each trend from which R2 and P values were calculated. RESULTS: Annual total admissions per 100â 000 hospitalizations due to WD were 1075, 1180, 1140, and 1330 ( R2 â =â 0.75; P â =â 0.13) from 2016 to 2019. Within the demographics, there was an increase in admissions among patients greater than 65 years of age ( R2 â =â 0.90; P â =â 0.05) and White patients ( R2 â =â 0.97; P â =â 0.02). Assessing WD-related mortality rates, there was an increase in the mortality rate among those in the first quartile of income ( R2 â =â 1.00; P â <â 0.001). The total cost for WD-related hospitalizations was $20.90, $27.23, $24.20, and $27.25 million US dollars for the years 2016, 2017, 2018, and 2019, respectively ( R2 â =â 0.47; P â =â 0.32). There was an increasing total cost trend for Asian or Pacific Islander patients ( R2 â =â 0.90; P â =â 0.05). Interestingly, patients with cirrhosis demonstrated a decreased trend in the total costs ( R2 â =â 0.97; P â =â 0.02). CONCLUSION: Our study demonstrated that certain ethnicity groups, income classes and comorbidities had increased admissions or costs among patients admitted with WD.

BACKGROUND AND AIMS: Primary sclerosing cholangitis (PSC) can result in hepatic decompensation and require liver transplantation (LT). This study investigates the effect of the sex of the donor and recipient as a prognostic risk factor for adverse outcomes after LT in patients with PSC. METHODS: UNOS registry was used to select LT patients with PSC from 1987 to 2019. The study cohort was stratified based on the sex of the recipient and further subdivided based on the sex of the donor. The primary endpoints of this study were all-cause mortality and graft failure, which were evaluated using a sequential Cox regression analysis. RESULTS: This study included 2829 patients; 906 female recipients were transplanted from 441 male donors and 465 female donors. 1923 male recipients were transplanted from 1194 male donors and 729 female donors. Within the mismatch analyses, the male-to-male recipients also had a significantly reduced hazard ratio of graft failure compared to female-to-male transplants [aHR 0.51, 95% confidence interval (CI) 0.33-0.79, P â =â 0.003]. No difference in graft failure was observed in the mismatched female recipient subgroup. The mismatched male recipient group also showed a decreased hazard ratio of mortality from graft rejection and respiratory causes. No differences in specific mortality causes were identified in the mismatched female recipient group. CONCLUSION: This study demonstrated an increase in the risk of graft failure and mortality secondary to graft failure in male recipients of female donor livers. No differences in mortality or graft failure were identified in female recipients of male livers.
