Clinical and Morphological Evaluation of Erosive and Ulcerative Gastric Lesions in Patients with Rheumatoid Arthritis.

Background: One of the most important problems associated with the treatment of Rheumatoid Arthritis (RA) is erosive-ulcerative lesions (EUL) of the gastroduodenal zone, which is associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs).

Aims: Our research aims to study the clinical and histo-morphological criteria for forming the EUL of the gastroduodenal zone in patients with RA.

Methods: Patients were divided into 3 groups, depending on the presence of an EUL, according to Fibrogastroduodenoscopy (FGDS) data with a negative test for H.
