Community-acquired pneumonia is currently one of the most common infectious diseases in the world. At the same time, the inflammation that occurs in community-acquired pneumonia, along with hypoxia, is one of the typical pathological processes that is associated with the introduction of an infecting agent. Under its influence, lipid peroxidation is activated through a cascade of reactions, which contributes to the formation of oxidative stress, accompanied by damage to the structures of various cells, including hepatocytes. The purpose of the study: to evaluate the clinical and functional state of the liver in the treatment of community-acquired pneumonia. Materials and methods: There were 120 people under observation, who were divided into 2 groups, receiving standard therapy for community-acquired pneumonia and patients receiving additional meglumin sodium succinate. The clinical and functional state of the liver was analyzed. Conclusions: when adding meglumin sodium succinate to the treatment of community-acquired pneumonia, the clinical and functional state of the liver in patients improves.
