Background:Undifferentiated arthritis (UDA) is an inflammatory arthritis that does not meet the criteria for any rheumatologic disease. Early verification of UDA is currently one of the main goals of modern rheumatology, since a diagnosis established at an early date allows determining a therapeutic strategy. The high social significance of arthritis lies in the predominant lesion of people of working age, the steady progression of the disease, early disability and a reduction in life expectancy.Objectives:To study the gender characteristics of verification of the diagnosis of undifferentiated arthritis.Methods:A retrospective analysis of 74 case histories of patients diagnosed with UDA was carried out. The study group consisted of 26 men and 48 women, mean age 50.6 ± 4.3 years. All patients underwent a comprehensive laboratory and instrumental examination according to the standard of an articular syndrome of unclear genesis.Results:According to the data obtained, the duration of the articular syndrome averaged 2.53 ± 1.2 years. In 29 patients (21.6% of women and 17.6% of men), on average, after 1.72 ± 0.9 years, the diagnosis of NDA was clarified. Taking into account modern diagnostic criteria, the following diseases were verified: rheumatoid arthritis in 13.5% (12.2% in women and 1.3% in men), ankylosing spondylitis in 10.8% (2.7% in women and 8.1% in men). Osteoarthritis, psoriatic arthritis and APS were diagnosed in 5.4%, 1.4% and 1.4% of women, and gouty arthritis, bone tuberculosis and HIV in 4.1%, 1.4% and 1.4% of men respectively. In 60.8% (43.2% in women and 17.6% in men), the etiology of arthritis was not verified.Conclusion:In a third of patients with UDA, diagnosis verification takes about 2 years on average. In more than half of patients, the diagnosis remains the same. According to the data obtained, rheumatoid arthritis was more often verified in women, while ankylosing spondylitis in men, which is consistent with statistical data.Disclosure of Interests:None declared
