A 60-day oral LOLA course was not better than placebo in treating MHE, but was useful in preventing further episodes of OHE.

Introduction. Spontaneous bacterial peritonitis (SBP) has a deleterious clinical impact in end-stage liver disease, and multidrug resistance has increased, raising concern about effectiveness of traditional antibiotic regimens. Patients and Methods. Single-center retrospective study of ascitic fluid infections in cirrhotic patients. Results. We analyzed medical records related to 2129 culture-positive ascitic fluid and found 183 samples from cirrhotic patients. There were 113 monobacterial SBP cases from 97 cirrhotic patients; 57% of patients were male; hepatitis C and alcohol were the main etiologies for cirrhosis. Multidrug resistant bacteria were isolated in 46.9% of SBP samples, and third-generation cephalosporin and quinolone resistant reached 38.9% and 25.7% of SBP cases. Conclusion. SBP due to multidrug resistant bacteria is a growing problem, and one should consider reported resistance profiles for the decision-making process of empirical first-line treatment prescription.

Introduction. Acute-on-chronic liver failure (ACLF) is an acute liver decompensation in cirrhotic patients, which leads to organ failures and high short-term mortality. The treatment is based on the management of complications and, in severe cases, liver transplantation. Since specific treatment is unavailable, we aimed to evaluate the safety and initial efficacy of bone marrow mesenchymal stem cells (BM-MSC) in patients with ACLF Grades 2 and 3, a population excluded from previous clinical trials. Methods. This is a randomized placebo-controlled phase I-II single center study, which enrolled 9 cirrhotic patients from 2018 to 2020, regardless of the etiology. The control group (n = 5) was treated with standard medical therapy (SMT) and placebo infusion of saline. The intervention group (n = 4) received SMT plus 5 infusions of 1 × 106 cells/kg of BM-MSC for 3 weeks. Both groups were monitored for 90 days. A Chi-square test was used for qualitative variables, and the t-test and Mann–Whitney U test for quantitative variables. The Kaplan–Meier estimator was used to build survival curves. In this study, we followed the intention-to-treat analysis, with a significance of 5%. Results. Nine patients with a mean Child–Pugh (CP) of 12.3, MELD of 38.4, and CLIF-C score of 50.7 were recruited. Hepatitis C and alcohol were the main etiologies. The average infusion per patient was 2.9 and only 3 patients (2 in control and 1 in the BM-MSC group) received all the protocol infusions. There were no infusion-related side effects, although one patient in the intervention group presented hypernatremia and a gastric ulcer, after the third and fifth infusions, respectively. The survival rate after 90 days was 20% (1/5) for placebo versus 25% (1/4) for the BM-MSC. The patient who completed the entire MSC protocol showed a significant improvement in CP (C-14 to B-9), MELD (32 to 22), and ACLF (grade 3 to 0). Conclusion. BM-MSC infusion is safe and feasible in patients with ACLF Grades 2 and 3.

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.

BACKGROUND: Acute kidney injury (AKI) is a common and severe complication of cirrhosis. OBJECTIVE: To evaluate the impact of AKI staging on 30-day mortality of patients with cirrhosis. METHODS: We performed a retrospective cohort study of hospitalized patients with cirrhosis. Acute kidney injury (AKI) was diagnosed according to the International Club of Ascites recommendations and staged according to the European Association for the Study of the Liver guidelines. Comparisons between groups were made by one-way analysis of variance and Tukey test. Chi-square was calculated for dichotomous variables. Comparisons of renal impairment status among patients were performed using Kaplan-Meier statistics and differences between groups were analyzed using the log-rank test. A P-value <0.05 was considered to be statistically significant. RESULTS: Two hundred and thirty-two patients were included in the study. The diagnosis of AKI was performed in 98 (42.2%) of them. The overall 30-day mortality was 19.8% (46/232). Mortality increased as the degree of AKI progressed. Among patients who did not have AKI, mortality was 5.2% (7/134). When compared to patients without AKI, patients diagnosed with AKI stage 1a had mortality of 12.1% (4/33, P=0.152); patients with AKI stage 1b had mortality of 45% (18/40, P<0.001); and patients with AKI stages 2 or 3 had mortality of 68% (17/25, P<0.001). Moreover, it is noteworthy that full response to treatment was associated to a decreased mortality when compared to patients who did not show complete recovery of renal function (14.3% vs 57.9%, P<0.001). CONCLUSION: AKI stages 1b or greater, but not AKI stage 1a, are associated to higher 30-day mortality of patients with cirrhosis.
