Effect of a monitored exercise protocol in cerebral and hepatic hemodynamics in patients with cirrhosis and portal hypertension.

BACKGROUND: Physical exercise (PE) has been proven to be beneficial in patients with cirrhosis; effects in cognitive function and cerebral hemodynamics, are yet to be explored. AIM: To evaluate the effects of a PE program (LFN-exercise protocol) in hepatic/cerebral hemodynamics. METHODS: Randomized open clinical trial in patients with cirrhosis; Control: Diet(n = 13),Intervention: Diet + exercise(n = 14) for 12 weeks. Patients received an educational session, mental exercises (printed book and sudoku), and high-protein diet. Exercise intervention consisted of walking 4 times/week with an intensity rated between 12 and 14 on the Borg scale, monitored through bracelet accelerometers. Patients received weekly text messages to encourage adherence and had monthly in-person visits. RESULTS: Patients were mainly Child-Pugh A(88.9 %), median MELD 8(8-10), mean age 53±8 years. In the exercise group the number of steps increased from 9667±3008 to 11,931±4463 (p = 0.002), vs 8004±3224 to 8903±3504 (p = 0.053) in controls. Exercise decreased HVPG from 11(8-14) to 8(6-11)mmHg (p = 0.032) vs no change in the control group from 14(12-16) to 15(11-17)mmHg (p = 0.959). Intervention group showed better cerebral hemodynamics, cognitive function, nutritional status and quality of life after the intervention. Adherence was >90 %, with no adverse events. CONCLUSION: The LFN-exercise protocol improves portal hypertension, cerebral hemodynamics and cognitive function, as well as nutritional status and quality of life. GOV NUMBER: NCT03932552.

Liver fibrosis in patients with metabolic associated fatty liver disease is a risk factor for adverse outcomes in COVID-19.

BACKGROUND: Metabolic diseases are risk factors for severe Coronavirus disease (COVID-19), which have a close relationship with metabolic dysfunction-associated fatty liver disease (MAFLD). AIMS: To evaluate the presence of MAFLD and fibrosis in patients with COVID-19 and its association with prognosis. METHODS: Retrospective cohort study. In hospitalized patients with COVID-19, the presence of liver steatosis was determined by computed tomography scan (CT). Liver fibrosis was assessed using the NAFLD fibrosis score (NFS score), and when altered, the AST to platelet ratio index (APRI) score. Mann-Whitney U, Student´s t-test, logistic regression analysis, Kaplan-Meier curves and Cox regression analysis were used. RESULTS: 432 patients were analyzed, finding steatosis in 40.6%. No differences in pulmonary involvement on CT scan, treatment, or number of days between the onset of symptoms and hospital admission were found between patients with and without MAFLD. The presence of liver fibrosis was associated with higher severity scores, higher levels of inflammatory markers, requirement of mechanical ventilation, incidence of acute kidney injury (AKI), and higher mortality than patients without fibrosis. CONCLUSION: The presence of fibrosis rather than the presence of MAFLD is associated with increased risk for mechanical ventilation, development of AKI, and higher mortality in COVID-19 patients.

Hepatic manifestations in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a multi-organic autoimmune disease with a wide variety of clinical manifestations. However, hepatic dysfunction is not included in the diagnostic criteria for the disease and has not been recognized properly. The spectrum of hepatic involvement described in these patients ranges from abnormalities in liver function tests (LFTs) to fulminant hepatic failure. Usually, abnormalities in LFTs are only mild and transient, have a hepatocellular pattern and are not related to SLE but rather are mostly drug related. The most frequent finding on liver biopsy is steatosis (non-alcoholic fatty liver disease). Patients do not frequently progress to advanced chronic liver disease, and their outcome is favourable. Those who develop cirrhosis have traditional risk factors, such as other non-SLE-related conditions. In this work, we aim to review hepatic manifestations in patients with SLE, as well as the diagnostic and therapeutic approaches used for different liver diseases in these patients.

Clinical characteristics and treatment outcomes in patients with liver cirrhosis and lymphoma.

BACKGROUND: A significant number of patients with liver cirrhosis concomitantly develop some type of solid or hematological cancer, including lymphoma. Treatment of patients with lymphoma and cirrhosis is challenging for physicians due to the clinical characteristics related to cirrhosis, including biochemical and functional abnormalities, as well as portal hypertension and lack of scientific evidence, limiting the use of chemotherapy. Currently, experts recommend only offering oncological treatment to patients with compensated cirrhosis. AIM: To evaluate the clinical characteristics and treatment outcomes in patients with cirrhosis and lymphoma treated with chemotherapy. METHODS: This was a case-control study conducted at a tertiary care center in Mexico. Data was recorded from medical files and from 8658 possible candidates with cirrhosis and/or lymphoma (2000 to 2018). Only 23 cases had both diseases concomitantly; 10 patients with cirrhosis and lymphoma (cases) met the selection criteria and were included, and 20 patients with lymphoma (controls) were included and matched according to age, sex, and date of diagnosis, type and clinical stage of lymphoma. All patients received treatment with chemotherapy. For statistical analysis, descriptive statistics, Shapiro-Wilk test, Mann-Whitney U test, chi-square test and Fisher's exact test were used. Survival was evaluated using Kaplan-Meier curves and Log-rank test. RESULTS: There were differences in biochemical variables inherent to liver disease and portal hypertension in patients with cirrhosis. The most frequent etiology of cirrhosis was hepatitis C virus (50%); 80% were decompensated, the median Child-Turcotte-Pugh score was 7.5 (6.75-9.25), and mean Model for End-stage Liver Disease was 11.5 ± 4.50. Regarding lymphomas, non-Hodgkin's were the most common (90%), and diffuse large B cell subtype was the most frequent, with a higher International Prognostic Index in the cases (3 vs 2, P = 0.049). The chemotherapy regimens had to be adjusted more frequently in the case group (50% vs 5%, P = 0.009). The complications derived from chemotherapy were similar between both groups (80% vs 90%, P = 0.407); however, non-hematological toxicities were more common in the case group (30% vs 0%, P = 0.030). There was no difference in the response to treatment between groups. Survival was higher in the control group (56 wk vs 30 wk, P = 0.269), although it was not statistically significant. CONCLUSION: It may be possible to administer chemotherapy in selected cirrhotic patients, regardless of their severity, obtaining satisfactory clinical outcomes. Prospective clinical trials are needed to generate stronger recommendations.
