ABSTRACT

PURPOSE: Indications for liver transplantation (LT) vary across age groups. We identified predictors of outcomes for teenage LT waitlisted candidates and recipients in the United States from 2008 to 2022. METHODS: The Scientific Registry of Transplant Recipients 2008-2022 provided data (clinical, sociodemographic, indications for LT, outcomes) for all teenagers (13-19 years) waitlisted for LT in the United States. Sociodemographic and clinical characteristics, including primary listing diagnoses, were evaluated and compared by age group (13-16 vs. 17-19 years) among waitlisted teenage candidates. RESULTS: There were 2,813 teenage LT candidates listed between 2008 and 2022. The most common LT indication was acute liver disease (23.5%), followed by biliary atresia or hypoplasia (11.9%), autoimmune hepatitis (11.1%), and primary sclerosing cholangitis (9.7%). In contrast, chronic viral hepatitis, metabolic dysfunction-associated steatotic liver disease, and alcohol-related liver disease (the most common indications in adults) did not exceed 1% each; 2.8% had hepatocellular carcinoma. Excluding the two most recent years, 67.2% of candidates received a transplant; mean time to transplant was 217.0 days (standard deviation 371.6). Independent predictors of receiving a transplant were a more recent calendar year, younger age, higher model for end-stage liver disease score, and an acute liver disease diagnosis (all p < .05). Among the LT group, 3-year survival was 90%, with an improving survival trend. Higher post-transplant mortality was associated with earlier years of transplantation, older age, having Medicaid, being retransplanted, and having hepatocellular carcinoma (adjusted hazard ratios >1, all p < .05). DISCUSSION: Indications for LT among US teenagers are different from adults or younger children. There is a trend toward improved post-transplant outcomes.

ABSTRACT

Meckel diverticulum is the most common congenital variation of the gastrointestinal tract arising from incomplete obliteration of the vitelline duct during gestation. In most cases, individuals are asymptomatic. This is a case of a 38-year-old patient with hematochezia in whom Meckel diverticulum was diagnosed. A mass was identified within the diverticulum. Histopathological and immunohistochemical studies revealed a well-differentiated neuroendocrine tumor. The development of tumors in Meckel diverticulum is rare, and when identified, only 0.5%-3.2% of these tumors are found to be malignant. Furthermore, gastrointestinal bleeding is an infrequent clinical feature of neuroendocrine tumors. A unique aspect of this case was that numerous imaging studies and endoscopic procedures were unable to definitively identify the presence of Meckle diverticulum and underlying neuroendocrine tumor. Through a high clinical suspicion and collaboration with surgical colleagues, an exploratory laparotomy was performed, which ultimately led to the identification and diagnosis of the underlying pathology.

ABSTRACT

BACKGROUND: The high prevalence of obesity in the United States drives the burden of NASH, recently renamed as metabolic dysfunction-associated steatohepatitis (MASH). We assessed the most recent trends in liver transplantation in the United States. METHODS: The Scientific Registry of Transplant Recipients (SRTR 2013-2022) was used to select adult (18 years or above) candidates who underwent liver transplant. RESULTS: There were 116,292 candidates who underwent liver transplant with known etiology of chronic liver disease. In candidates without HCC, the most common etiology was alcohol-associated liver disease (ALD), increasing from 23% (2013) to 48% (2022), followed by NASH/MASH, which increased from 19% to 27%; the rates of viral hepatitis decreased (chronic hepatitis C: 28%-4%; chronic hepatitis B: 1.8%-1.1%) (all trend p<0.01). The proportion of HCC decreased from 25% (2013-2016) to 17% (2021-2022). Among HCC cohort, the proportion of chronic hepatitis C decreased from 60% (2013) to 27% (2022), NASH/MASH increased from 10% to 31%, alcohol-associated liver disease increased from 9% to 24% (trend p<0.0001), and chronic hepatitis B remained stable between 5% and 7% (trend p=0.62). The rapid increase in the proportion of NASH/MASH in HCC continued during the most recent study years [20% (2018), 28% (2020), 31% (2022)]; the trend remained significant after adjustment for age, sex, ethnicity, obesity, and type 2 diabetes. CONCLUSIONS: Liver transplant etiologies in the United States have changed over the last decade. Alcohol-associated liver disease and NASH/MASH remain the 2 most common indications for transplantation among those without HCC, and NASH/MASH is the most common in patients with HCC.

ABSTRACT

As the prevalence of obesity and type 2 diabetes increases around the world, the prevalence of nonalcoholic fatty liver disease (NAFLD) has grown proportionately. Although most patients with NAFLD do not experience progressive liver disease, about 15% to 20% of those with nonalcoholic steatohepatitis can and do progress. Because liver biopsy's role in NAFLD has become increasingly limited, efforts have been undertaken to develop non-invasive tests (NITs) to help identify patients at high risk of progression. The following article discusses the NITs that are available to determine the presence of NAFLD as well as high-risk NAFLD.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Data about 30-day readmission for patients with chronic liver disease (CLD) and their contribution to CLD healthcare burden are sparse. Patterns, diagnoses, timing and predictors of 30-day readmissions for CLD from 2010-2017 were assessed. MATERIALS AND METHODS: Nationwide Readmission Database (NRD) is an all-payer, all-ages, longitudinal administrative database, representing 35 million discharges in the US population yearly. We identified unique patients discharged with CLD including hepatitis B (HBV) and C (HCV), alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) from 2010 through 2017. Survey-weight adjusted multivariable analyses were used. RESULTS: From 2010 to 2017, the 30-day readmission rate for CLD decreased from 18.4% to 17.8% (p=.008), while increasing for NAFLD from 17.0% to 19. 9% (p<.001). Of 125,019 patients discharged with CLD (mean age 57.4 years, male 59.0%) in 2017, the most common liver disease was HCV (29.2%), followed by ALD (23.5%), NAFLD (17.5%), and HBV (4.3%). Readmission rates were 20.5% for ALD, 19.9% for NAFLD, 16.8% for HCV and 16.7% for HBV. Compared to other liver diseases, patients with NAFLD had significantly higher risk of 30-day readmission in clinical comorbidities adjusted model (Hazard ratio [HR]=1.08 [95% confidence interval 1.03-1.13]). In addition to ascites, hepatic encephalopathy, higher number of coexisting comorbidities, comorbidities associated with higher risk of 30-day readmission included cirrhosis for NALFD and HCV; acute kidney injury for NAFLD, HCV and ALD; HCC for HCV, and peritonitis for ALD. Cirrhosis and cirrhosis-related complications were the most common reasons for 30-day readmission, followed by sepsis. However, a large proportion of patients (43.7% for NAFLD; 28.4% for HCV, 39.0% for HBV, and 29.1% for ALD) were readmitted for extrahepatic reasons. Approximately 20% of those discharged with CLD were readmitted within 30 days but the majority of readmissions occurred within 15 days of discharge (62.8% for NAFLD, 63.7% for HCV, 74.3% for HBV, and 72.9% for ALD). Among readmitted patients, patients with NAFLD or HCV readmitted ≤30-day had significantly higher costs and risk of in-hospital mortality (NAFLD +5.69% change [95% confidence interval, 2.54%-8.93%] and odds ratio (OR)=1.58 [1.28-1.95]; HCV +9.85% change [95%CI:6.96%-12.82%] and OR=1.31, 1.08-1.59). CONCLUSIONS: Early readmissions for CLD are prevalent causing economic and clinical burden to the US healthcare system, especially NAFLD readmissions. Closer surveillance and attention to both liver and extrahepatic medical conditions immediately after CLD discharge is encouraged.

ABSTRACT

BACKGROUND: Mortality benefits of vigorous leisure time physical activity (LTPA) among adults with NAFLD is not known. AIM: To investigate association between LTPA and reduction in all-cause mortality among adults with NAFLD. METHODS: We used NHANES (1999-2006) self-reported PA data for adults (≥40 years) with mortality follow-up through December 31, 2015. US-Fatty Liver Index in absence of secondary causes identified NAFLD. Moderate and vigorous LTPA were calculated by the 2018 PA Guidelines for Americans. RESULTS: NAFLD prevalence among 5211 adults (46.2% male; 75.8% white; mean age 53.2 years) was 32.7%. Adults with NAFLD were less likely to report the recommended minimal PA (≥ 150 min/week, 55.5% vs 64.8%) or highly active PA (≥300 min/week, 39.2% vs 48.5%) compared to adults without NAFLD. Over a median follow-up of 12.3 years, 355 deaths among adults with NAFLD and 510 deaths among adults without NAFLD were registered. In the metabolic comorbidities-adjusted model, adults with NAFLD who reported ≥50% of their total PA as vigorous activity had a 56% reduction in all-cause mortality risk (HR:0.44, 95%CI: 0.25-0.76) and cancer-specific mortality risk (HR: 0.21, 0.06-0.66) but not cardiac-specific mortality (p > 0.05) compared to adults with NAFLD who did not report any LTPA. This association remained significant even among adults with NAFLD who met the recommended minimal PA, among adults with NAFLD who reported any LTPA, and among adults with NAFLD who had metabolic abnormalities and in sensitivity analysis. CONCLUSIONS: Engaging in vigorous activity is beneficial for adults with NAFLD - especially those with metabolic abnormalities.

ABSTRACT

BACKGROUND AND AIM: The causes of chronic liver disease (CLD) among adults have changed. Data are lacking on trends among youth. We determined the trends and changes in the global burden of CLD among adolescents and young adults using Global Burden of Disease (GBD) data (2009-2019). APPROACH AND RESULTS: The GBD study estimation methods were used to assess CLD prevalence, incidence, and deaths (21 GBD regions). Annual percent change (APC) calculation by joinpoint regression modeling. Age groups were 15-19, 20-24, and 25-29 years old. Globally in 2019, the 15-29 group accounted for 17.2% (0.29 billion) of CLD prevalent cases, 11.2% (n = 232,072) CLD incident cases, and 3.8% (n = 55,515) CLD deaths. Between 2009 and 2019, CLD prevalence rate increased annually among 25-29 (APC = +0.41%, p < 0.001); remained stable among 20-24 (APC = +0.02%, p = 0.582); and decreased among 15-19 (APC = -2.13%, p < 0.001). CLD prevalence increases were driven by the proportion with NAFLD (15-19: 40.8% to 52.9%, p < 0.001); 20-24: 57.6% to 62.7%, p < 0.001); and 25-29: 66.9% to 70.1%, p < 0.001); the proportion with HBV decreased across all age groups. NAFLD prevalence worsening trend (APC ≥ 0%) was global. Overall CLD death rate decreased annually in all age groups, driven by the decrease in the proportion with HBV [aged 15-19 (from 5.90% to 5.20%, p < 0.001); aged 20-24 (from 18.62% to 16.37%, p < 0.001); and aged 25-29 (from 28.69% to 25.28%, p < 0.001)]; from 2015 to 2019, CLD death rate for HCV (APC = +1.46%) and NAFLD (APC = +2.26%) increased. CONCLUSIONS: Over the past decade, the causes of CLD among 15-29-year-olds have shifted: viral hepatitis remains the most common cause of CLD deaths, but the global burden of HBV incidence is decreasing, whereas NAFLD is the main driver for increased CLD incidence.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Cause of mortality in patients with chronic liver diseases (CLDs) may differ based on underlying etiology of liver disease. Our aim was to assess different causes of death in patients with the most common types of CLD using a national database from the United States. MATERIALS AND METHODS: Death data from 2008 and 2018 from the National Vital Statistics System (NVSS) by the National Center for Health Statistics (NCHS) were used. The rank of cause-of-death for each etiology of CLDs was assessed. Causes of death were classified by the ICD-10 codes. Liver-related deaths included liver cancer, cirrhosis and CLDs. RESULTS: Among a total of 2,826,531 deaths in 2018, there were 85,807 (3.04%) with underlying CLD (mean age at death 63.0 years, 63.8% male, 70.8% white). Liver-related mortality was the leading cause of death for all types of CLD [45.8% in non-alcoholic fatty liver disease (NAFLD), 53.0% in chronic hepatitis C (CHC), 57.8% in chronic hepatitis B (CHB), 81.8% in alcoholic liver disease (ALD)]. This was followed by death from cardiac causes (NAFLD 10.3%, CHC 9.1%, CHB 4.6%, ALD 4.2%) and extrahepatic cancer (NAFLD 7.0%, CHC 11.9%, CHB 14.9%, ALD 2.1%). Although liver cancer was the leading cause of cancer death, lung, colorectal and pancreatic cancer were also common causes of cancer death. CONCLUSIONS: Among deceased patients with CLD, underlying liver disease was the leading cause of death. Among solid cancers, liver cancer was the leading cause of cancer-related mortality.
