Introduction: Medico-social significance of osteoarthritis is due to a number of factors, one of which is associated with the need for long-term anti-inflammatory therapy, which is associated with undesirable side effects. The aim: Identify the features of the course of chronic gastritis in patients taking selective NSAIDs for osteoarthritis. Materials and methods: Were examined 122 patients with osteoarthrosis, who had verified chronic gastritis in the anamnesis (50 males and 72 females), aged from 42 to 64. Control group included 40 patients with osteoarthrosis without gastroduodenal zone pathology in the anamnesis. For arthralgia relief, patients were prescribed to intake meloxicam (average dose - 12.5±1.39 mg/day) or nimesulide (average dose - 150±14.91 mg/day). Results: It was determined that prescription of selective NSAIDs (meloxicam and nimesulide) raised the risk of NSAIDs gastropathy/dyspepsia in 2.9 times (P<0.03) in patients with chronic gastritis in the anamnesis than in patients without associated gastroduodenal zone pathology. Atrophy of gastric mucous membrane was associated with higher risks (P>0.05) of erosive gastropathy. Conclusions: With the purpose of gastropathy prevention upon taking NSAIDs, patients with chronic gastritis in the anamnesis are recommended to undergo gastroprotective therapy.
