METHOD FOR PREDICTING RISK OF DEVELOPING COMPLICATED GASTRIC ULCER BASED ON DETERMINING EXPRESSION LEVEL OF MICRORNA-155 Russian patent published in 2024 - IPC G01N33/58 C12Q1/6806 C12Q1/686 G16H50/30 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to medical diagnostics, and can be used for prediction of risk of complicated gastric ulcer. Gastric biopsy is carried out with sampling of two biopsy materials: in the body region and in the antrum along the greater curvature, one biopsy material along the lesser curvature in the body region. Expression level of microRNA-155 is determined, the arithmetic mean is calculated based on the results of three repetitions. If value is 4.286±0.261, a high risk of developing complicated gastric ulcer is predicted.

EFFECT: method provides more accurate prediction of a high risk of developing complicated gastric ulcer by determining the expression level of microRNA-155 in gastric biopsy materials.
