Article Synopsis
  • * Specific cytokines such as IL-1b, IL-6, and TNF-a were associated with both higher levels of harmful gut bacteria and the severity of cirrhosis symptoms like ascites, suggesting a connection between gut health and liver disease progression.
  • * The results indicate that certain gut bacteria populations correlate directly with inflammatory cytokine levels, pointing to a potential link between gut dysbiosis and systemic inflammation in cirrhosis patients.

Background: The gut-liver axis and bacterial translocation are important in cirrhosis, but there is no available universal biomarker of cellular bacterial translocation, for which presepsin may be a candidate.

Aim: To evaluate the relationship of the blood presepsin levels with the state of the gut microbiota in cirrhosis in the absence of obvious infection.

Methods: This study included 48 patients with Child-Pugh cirrhosis classes B and C and 15 healthy controls.

Gut dysbiosis and subclinical intestinal damage are common in cirrhosis. The aim of this study was to examine the association of intestinal damage biomarkers (diamine oxidase [DAO], claudin 3, and intestinal fatty acid binding protein [I-FABP; FABP2]) with the state of the gut microbiota in cirrhosis. The blood levels of DAO were inversely correlated with blood levels of claudin 3, lipopolysaccharide (LPS), presepsin, TNF-α, and the severity of cirrhosis according to Child-Pugh scores.

Our aim was to study the association of endothelial dysfunction biomarkers with cirrhosis manifestations, bacterial translocation, and gut microbiota taxa. The fecal microbiome was assessed using 16S rRNA gene sequencing. Plasma levels of nitrite, big endothelin-1, asymmetric dimethylarginine (ADMA), presepsin, and claudin were measured as biomarkers of endothelial dysfunction, bacterial translocation, and intestinal barrier dysfunction.

(1) : The aim was to evaluate the effectiveness of the probiotic containing in the treatment of small intestinal bacterial overgrowth (SIBO) in patients with decompensated cirrhosis. (2) : This was a blinded, randomized, placebo-controlled study. (3) : After 3 months of treatment, SIBO was absent in 80.

Article Synopsis
  • The study evaluated how gut bacteria imbalances (dysbiosis) affect blood circulation changes (hyperdynamic circulation) in patients with cirrhosis and how these changes relate to disease complications.
  • It involved 47 cirrhosis patients whose stool microbiomes were examined, revealing patients with hyperdynamic circulation had more severe liver conditions and specific blood marker changes compared to those with normal circulation.
  • Key findings showed changes in gut bacteria, with increased levels of Proteobacteria and decreased levels of Bacteroidetes, were linked to blood flow dynamics, suggesting that certain gut bacteria may influence systemic vascular resistance and heart function.

Article Synopsis
  • Small intestinal bacterial overgrowth (SIBO) occurs when there is an abnormal increase in bacteria in the small intestine, affecting around 33.8% of patients with gastrointestinal issues, and is linked to smoking and symptoms like bloating and abdominal pain.
  • * SIBO can complicate various diseases (like IBS, Crohn's disease, and diabetes) and is notably influenced by factors like age, motor dysfunction in the intestine, and the use of proton pump inhibitors.
  • * The connection between SIBO and the severity of certain diseases highlights the need for further research on how treating SIBO could improve patient outcomes.

Background: Small intestinal bacterial overgrowth (SIBO) is associated with numerous manifestations of cirrhosis. To determine whether the presence of SIBO affects the prognosis in cirrhosis was the aim of the study.

Methods: This prospective cohort study included 50 patients.

Background: Bacterial translocation exacerbates the hyperdynamic circulation observed in cirrhosis and contributes to a more severe disease course. Probiotics may reduce bacterial translocation and may therefore be useful to redress the circulatory imbalance.

Aim: To investigate the effect of probiotics on hemodynamic parameters, systemic inflammation, and complications of cirrhosis in this randomized placebo-controlled trial.

Background: Gut dysbiosis and small intestinal bacterial overgrowth (SIBO) are commonly observed in patients with cirrhosis. Despite the substantial number of articles describing the relations between disorders of gut microbiota and various manifestations of cirrhosis, dysbiosis and SIBO were always studied separately.

Aim: To study the relationship of gut dysbiosis and SIBO in cirrhosis.

Recent evidence suggests that the condition of the gut and its microbiota greatly influence the course of liver disease, especially cirrhosis. This introduces the concept of the gut-liver axis, which can be imagined as a chain connected by several links. Gut dysbiosis, small intestinal bacterial overgrowth, and intestinal barrier alteration lead to bacterial translocation, resulting in systemic inflammation.

Diarrhea is one of the manifestations of the novel coronavirus disease (COVID-19), but it also develops as a complication of massive antibiotic therapy in this disease. This study aimed to compare these types of diarrhea.We included patients with COVID-19 in a cohort study and excluded patients with chronic diarrhea, laxative use, and those who died during the first day of hospitalization.

The gut-liver axis plays an important role in the pathogenesis of various liver diseases. Probiotics are living bacteria that may be used to correct disorders of this axis. Notable progress has been made in the study of probiotic drugs for the treatment of various liver diseases in the last decade.

Article Synopsis
  • * Chronic hepatitis B and C have a well-documented relationship with these autoimmune disorders, while connections for hepatitis A are limited and for hepatitis E, largely controversial.
  • * It's recommended that patients presenting symptoms like uveitis or arthritis undergo testing for viral hepatitis, as the presence of these viruses could warrant antiviral treatment to address both infections and associated disorders.

Methods: The retrospective study included COVID-19 patients with C-reactive protein (CRP) levels of 60-150 mg/L.

As it was established in our previous studies, the proteins of human serum γ-globulin fraction could interact with copper or zinc ions distributed in the periglobular space, form metal complexes, and become able to perform effector functions differing due to the conformational shifts from those mediated by them in native conformation of their Fc regions. In the present work we have evaluated ability of the γ-globulin metal complexes formed with copper or zinc ions in the conditions like to the physiological ones to induce production or to regulate induction in the culture of freshly isolated human peripheral blood cells (PBC) of granulocyte (G) and granulocyte-macrophage (GM) colony-stimulating factors (CSF) as well as of vascular endothelial growth factor (VEGF). The γ-globulin metal complexes formed with both copper and zinc ions were found to similarly reduce production of GM-CSF, G-CSF, and VEGF induced in normal human PBC cultures by the control γ-globulins or by copper and zinc ions used alone.

This paper describes a teaching/service model that integrates inpatient, partial hospital, and intensive outpatient treatment. In this model, individual multidisciplinary treatment teams retain responsibility for a patient's care for any or all of three levels of intensity of services accessed during an episode of illness. This teaching/service model allows residents to follow patients for an average of 2.
