Portal vein thrombosis compromises the performance of MELD and MELD-Na scores in patients with cirrhosis.

BACKGROUND AND AIMS: The accuracy of model for end-stage liver disease (MELD) and MELD with sodium (MELD-Na) scores in reflecting the clinical outcomes of patients with cirrhosis and portal vein thrombosis (PVT) remains unclear. This study aimed to evaluate the performance of scores in predicting 90-day mortality in patients with cirrhosis and PVT. METHODS: Post hoc analysis was performed in two prospective cohorts (NCT02457637 and NCT03641872). The correlation between the MELD/MELD-Na score and 90-day liver transplantation (LT)-free mortality was investigated in patients with cirrhosis with and without PVT. RESULTS: In this study, 2826 patients with cirrhosis were included, and 255 (9.02%) had PVT. The cumulative incidence of 90-day LT-free mortality did not significantly differ between patients with and without PVT (log-rank P = 0.0854). MELD [area under the receiver operating curve (AUROC), 0.649 vs. 0.842; P = 0.0036] and MELD-Na scores (AUROC, 0.691 vs. 0.851; P = 0.0108) were compared in patients with and without PVT, regarding the prediction of 90-day LT-free mortality. In MELD < 15 and MELD-Na < 20 subgroups, patients with PVT had a higher 90-day LT-free mortality than those without PVT (7.91% vs. 2.64%, log-rank P = 0.0011; 7.14% vs. 3.43%, log-rank P = 0.0223), whereas in MELD ≥ 15 and MELD-Na ≥ 20 subgroups, no significant difference was observed between patients with and without PVT. CONCLUSIONS: The performance of MELD and MELD-Na scores in predicting 90-day LT-free mortality of patients with cirrhosis was compromised by PVT. MELD < 15 or MELD-Na < 20 may underestimate the 90-day LT-free mortality in patients with PVT.

Prevalence and clinical significance of serum sodium variability in patients with acute-on-chronic liver diseases: a prospective multicenter study in China.

BACKGROUND: No reports exist regarding the prevalence of different Na levels and their relationship with 90-day prognosis in hospitalized patients with acute-on-chronic liver disease (AoCLD) in China. Therefore, the benefit of hyponatremia correction in AoCLD patients remains unclear. METHODS: We prospectively collected the data of 3970 patients with AoCLD from the CATCH-LIFE cohort in China. The prevalence of different Na levels (≤ 120; 120-135; 135-145; > 145) and their relationship with 90-day prognosis were analyzed. For hyponatremic patients, we measured Na levels on days 4 and 7 and compared their characteristics, based on whether hyponatremia was corrected. RESULTS: A total of 3880 patients were involved; 712 of those developed adverse outcomes within 90 days. There were 80 (2.06%) hypernatremic, 28 (0.72%) severe hyponatremic, and 813 (20.95%) mild hyponatremic patients at admission. After adjusting for all confounding factors, the risk of 90-day adverse outcomes decreased by 5% (odds ratio [OR] 0.95; 95% confidence interval [CI] 0.93-0.97; p < 0.001), 24% (OR 0.76; 95% CI 0.70-0.84; p < 0.001), and 42% (OR 0.58; 95% CI 0.49-0.70; p < 0.001) as Na level increased by 1, 5, and 10 mmol/L, respectively. Noncorrection of hyponatremia on days 4 and 7 was associated with 2.05-fold (hazard ratio [HR], 2.05; 95% CI, 1.50-2.79; p < 0.001) and 1.46-fold (HR 1.46; 95% CI 1.05-2.02; p = 0.028) higher risk of adverse outcomes. CONCLUSIONS: Hyponatremia was an independent risk factor for a poor 90-day prognosis in patients with AoCLD. Failure to correct hyponatremia in a week after admission was often associated with increased mortality. (ClinicalTrials.gov number: NCT02457637, NCT03641872).

Lower platelet counts were associated with 90-day adverse outcomes in acute-on-chronic liver disease patients.

BACKGROUND: Chronic liver diseases (CLD), including cirrhosis and non-cirrhotic liver diseases, are globally widespread and create a serious disease burden. Platelet count is a clinically accessible and affordable prognostic indicator of liver disease. We investigated the relationship between platelet count and 90-day prognosis in patients with acute-on-chronic liver diseases (AoCLD). METHODS: A total of 3,970 patients with AoCLD from the Chinese Acute-on-Chronic Liver Failure (CATCH-LIFE) study, which included two prospective multi-center cohorts, were included in the study. We grouped the patients according to the platelet count and analyzed the 90-day adverse outcome (death or liver transplantation). RESULTS: In the final analysis, 3,939 patients with AoCLD were included, of whom 2,802 had definite liver cirrhosis. The cumulative incidence of 90-day adverse outcomes in patients increased with the change of platelet group (log-rank P<0.001). From univariate and multivariate analyses, platelet count was inversely associated with the incidence of 90-day adverse outcomes in patients (P for trend <0.001). The group with platelet count <20×109/L had the highest risk (odds ratio, 3.15; 95% confidence interval, 1.59-6.25), with 21 (36.8%) of these patients having adverse outcomes within 90 days. The risk of a 90-day adverse outcome in patients increased by 5% for every 10×109/L decrease in platelet count below 210×109/L. CONCLUSIONS: Lower platelet count was associated with a higher incidence of 90-day adverse outcomes in patients with AoCLD. Even within the normal platelet count range, the risk of a 90-day adverse outcome in patients increased with decreases in platelet count. TRIAL REGISTRATION: NCT02457637, NCT03641872.

Spontaneous Fungal Ascites Infection in Patients with Cirrhosis: An Analysis of 10 Cases.

INTRODUCTION: Spontaneous fungal ascites infection is a rare but devastating complication of cirrhosis. We aimed to analyse the clinical features, short-term mortality, and treatment of spontaneous fungal ascites infection in patients with cirrhosis. METHODS: We retrospectively studied ten patients with cirrhosis and spontaneous fungal ascites infections, and the clinical characteristics and outcomes were obtained. RESULT: The patients' mean age was 64 ± 13 years, and seven of the ten patients were men. Cirrhosis was primarily caused by infection with the hepatitis B virus. Candida albicans was the most frequently isolated fungus isolated from the ascites fluid. Three of the ten patients fulfilled the criteria of acute-on-chronic liver failure (ACLF) at baseline, and three of the remaining seven patients developed ACLF during hospitalisation. Of the ten patients, six had acute kidney injury (AKI), and six died within 28 days. Three patients did not receive antifungal treatment during hospitalisation because they died undiagnosed because of delays in the reporting of laboratory results. CONCLUSION: Patients with spontaneous fungal ascites infection had high incidence of AKI and 28-day mortality. Fungal cultures of ascitic fluid from patients with cirrhosis should be recommended to ensure optimal clinical management, especially in patients with severe liver disease and who received inadequate empirical antibacterial therapy. Hence, future studies should focus on the early diagnosis of fungal infection in patients with cirrhosis.
