Abstract:
Sepsis is characterized by a dysregulated immune response to infection leading to life-threatening organ dysfunction. Sepsis-induced liver injury is recognized as a powerful independent predictor of mortality in the intensive care unit. During systemic infections, the liver regulates immune defenses via bacterial clearance, production of acute-phase proteins (APPs) and cytokines, and metabolic adaptation to inflammation. Increased levels of inflammatory cytokines and impaired bacterial clearance and disrupted metabolic products can cause gut microbiota dysbiosis and disruption of the intestinal mucosal barrier. Changes in the gut microbiota play crucial roles in liver injury during sepsis. Bacterial translocation and resulting intestinal inflammation lead to a systemic inflammatory response and acute liver injury. The gut-liver crosstalk is a potential target for therapeutic interventions. This review analyzes the underlying mechanisms for the gut-liver crosstalk in sepsis-induced liver injury.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
