ABSTRACT

INTRODUCTION AND OBJECTIVES: Most epidemiological data on hepatocellular carcinoma (HCC) originate from resource-rich countries. We have previously described the epidemiology of HCC in South America through the South American Liver Research Network. Here, we provide an update on the changing epidemiology of HCC in the continent seven years since that report. MATERIALS AND METHODS: We evaluated all cases of HCC diagnosed between 2019 to 2021 in centers from six countries in South America. A templated, retrospective chart review of patient characteristics at the time of HCC diagnosis, including basic demographic, clinical and laboratory data, was completed. Diagnosis of HCC was made radiologically or histologically for all cases via institutional standards. RESULTS: Centers contributed to a total of 339 HCC cases. Peru accounted for 37% (n=125) of patients; Brazil 16% (n=57); Chile 15% (n=51); Colombia 14% (n=48); Argentina 9% (n=29); and Ecuador 9% (n=29). The median age at HCC diagnosis was 67 years (IQR 59-73) and 61% were male. The most common risk factor was nonalcoholic fatty liver disease (NAFLD, 37%), followed by hepatitis C (17%), alcohol use disorder (11%) and hepatitis B (12%). The majority of HCCs occurred in the setting of cirrhosis (80%). HBV-related HCC occurred at a younger age compared to other causes, with a median age of 46 years (IQR 36-64). CONCLUSIONS: We report dramatic changes in the epidemiology of HCC in South America over the last decade, with a substantial increase in NAFLD-related HCC. HBV-related HCC still occurs at a much younger age when compared to other causes.

ABSTRACT

AIM: To assess the impact of the different stages of acute kidney injury (AKI) on the prognosis of patients hospitalized with decompensated cirrhosis. METHODS: This was a prospective cohort study of consecutive patients admitted in two tertiary hospitals in southern Brazil. Participants were considered eligible if they were admitted for acute decompensation of cirrhosis. The main exposure factor was the onset of AKI. AKI stages were defined according the European recommendations. The outcomes evaluated were survival time and death rates at 28 and 90 days from hospital admission. A χ2 test was used to compare mortality between groups. Kaplan-Meier survival analyses were undertaken assessing time to event as days from AKI diagnosis to death or liver transplant. RESULTS: Two hundred and five patients were included in the study, and 121 met the criteria for AKI. Patients with AKI 1b, AKI 2 and AKI 3 had higher 90-day mortality than patients without AKI (P = 0.008, P < 0.001 and P < 0.001, respectively). However, there was no difference in 90-day mortality when patients with AKI 1a were compared with those without AKI (P = 0.742). The mean survival of patients without AKI was higher than that of patients with AKI 1b (591.4 and 305.4 days, respectively, P = 0.015), while there was no significant difference between the mean survival of patients without AKI and that of patients with AKI 1a (591.4 and 373.6 days, respectively, P = 0.198). CONCLUSION: Only AKI ≥1b seems to substantially impact mortality of patients hospitalized for acute decompensation of cirrhosis.
