Hypertonic seawater solution with brown algae extract Ascophillum nodosum in the treatment of acute rhinosinusitis

The article presents modern approaches to the modulation of cellular factors of innate immunity, oxidative stress factors when using a hypertonic seawater solution with Ascophillum nodosum brown algae extract (NaCl 15 g/l) in patients with acute rhinosinusitis. Characteristics of the children and research methods. The authors examined 102 children aged from 5 to 8 years, with a history of more than 5 episodes of acute rhinosinusitis per year. We evaluated the quantitative and qualitative composition of neutrophilic granulocytes in washes from the mucous membrane of the nasal cavity, the production of reactive oxygen species (ROS) by neutrophilic granulocytes, the content of lipid peroxidation products, enzymes of the antioxidant system - superoxide dismutase and catalase in nasal washes. Results. The authors found that the nasal spray of a hypertonic seawater solution with Ascophillum nodosum brown algae extract helps to normalize clinical picture, reduce number of relapses, restore functional and metabolic status of neutrophils of the nasal mucosa surface, restore balance of lipid peroxidation factors, antioxidant sustem enzymes - superoxide dismutase and catalase. © 2020 National Academy of Pediatric Science and Innovation.
